PART I

Item 1. Business

Overview

The Partnership was formed in April 2013 by SCW LLC. The Partnership owns a controlling interest comprised of 51.0% membership interest in Sisecam Wyoming, which is one of the largest and lowest cost producers of natural soda ash in the world, serving a global market from our facility in the Green River Basin of Wyoming. Our facility has been in operation for more than 50 years.

The following table sets forth certain operating data regarding our business:


	Year Ended December 31,
	2021		2020		2019		2018		2017
Operating and Other Data:	(thousands of short tons, except for ratio data)
Trona ore consumed	4,251.2		3,653.8		4,157.0		4,018.3		4,001.3
Ore to ash ratio(1)	1.56: 1.0		1.60: 1.0		1.51: 1.0		1.54: 1.0		1.50: 1.0
Ore grade(2)	86.3	%	86.6	%	86.6	%	85.8	%	88.4	%
Soda ash volume produced	2,720.5		2,279.3		2,752.0		2,613.4		2,666.9
Soda ash volume sold	2,813.5		2,221.9		2,759.1		2,613.2		2,705.4

(1)Ore to ash ratio expresses the number of short tons of trona ore used to produce one short ton of soda ash and liquor and includes our deca rehydration recovery process. In general, a lower ore to ash ratio results in lower costs and improved efficiency.

(2)Ore grade is the percentage of raw trona ore that is recoverable as soda ash free of impurities. A higher ore grade will produce more soda ash than a lower ore grade.

Trona, a naturally occurring soft mineral, is also known as sodium sesquicarbonate and consists primarily of sodium carbonate, or soda ash, sodium bicarbonate and water. We process trona ore into soda ash, which is an essential raw material in flat glass, container glass, detergents, chemicals, paper and other consumer and industrial products. The vast majority of the world’s accessible trona reserves are located in the Green River Basin. According to historical production statistics, approximately 30% of global soda ash is produced by processing trona, with the remainder being produced synthetically through chemical processes. The processing of soda ash from trona is the cheapest manner in which to produce soda ash. The costs associated with procuring the materials needed for synthetic production are greater than the costs associated with mining trona for trona-based production. In addition, trona-based production consumes less energy and produces fewer undesirable by-products than synthetic production.

Our principal executive offices are located at Five Concourse Parkway, Suite 2500, Atlanta, Georgia 30328, and our telephone number is (770) 375-2300. We make available, free of charge on our website at www.ciner.us.com our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, as soon as reasonably practicable after we electronically file such material with, or furnish such material to, the U.S. Securities and Exchange Commission (“SEC”).

Change in Control of Sisecam Chemicals

On December 21, 2021, Ciner Enterprises (which was the indirect owner of approximately 74% of the common units in the Partnership and 100% of the general partner), completed the following transactions pursuant to the definitive agreement which Ciner Enterprises entered into with Sisecam USA, a direct subsidiary of Şişecam Parent on November 20, 2021 (“Purchase Agreement”):

•Ciner Enterprises converted Ciner Resources Corporation into Sisecam Chemicals Resources LLC, a Delaware limited liability company ("Sisecam Chemicals"), and Ciner Wyoming Holding Co., a direct wholly-owned subsidiary of Sisecam Chemicals, into Sisecam Chemicals Wyoming LLC (“SCW LLC”), with SCW LLC in turn then directly owning approximately 74% of the common units in the Partnership and 100% of the general partner (collectively, the “Reorganization Transactions”);

Table of Contents

•subsequent to the Reorganization Transactions, Ciner Enterprises sold to Sisecam USA, and Sisecam USA purchased, 60% of the outstanding units of Sisecam Chemicals owned by Ciner Enterprises for a purchase price of $300 million (the “Sisecam Chemicals Sale”); and

•at the closing of the Sisecam Chemicals Sale, Sisecam Chemicals, Ciner Enterprises, and Sisecam USA entered into a unitholders and operating agreement (the “Sisecam Chemicals Operating Agreement”) (collectively such transactions, the “CoC Transaction”).

Pursuant to the terms of the Sisecam Chemicals Operating Agreement, Sisecam USA and Ciner Enterprises have a right to designate six directors and four directors, respectively, to the board of directors of Sisecam Chemicals. In addition, the Sisecam Chemicals Operating Agreement provides that (i) the board of directors of the general partner (the “MLP Board”) shall consist of six designees from Sisecam USA, two designees from Ciner Enterprises and three independent directors for as long as the general partner is legally required to appoint such independent directors and (ii) the Partnership’s right to appoint four managers to the board of managers of Sisecam Wyoming (the “Wyoming Board”) shall be comprised of three designees from Sisecam USA and one designee from Ciner Enterprises. Each of Sisecam USA and Ciner Enterprises shall vote all units over which such unitholder has voting control in Sisecam Chemicals to elect to the board of directors any individual designated by Sisecam USA and Ciner Enterprises. The Sisecam Chemicals Operating Agreement also requires the board of directors of Sisecam Chemicals to unanimously approve certain actions and commitments, including without limitation taking any action that would have an adverse effect on the master limited partnership status of the Partnership or any of its subsidiaries. As a result of Sisecam USA’s and Ciner Enterprise’s respective interests in Sisecam Chemicals and their respective rights under the Sisecam Chemicals Operating Agreement, each of Ciner Enterprises and Sisecam USA and their respective beneficial owners may be deemed to share beneficial ownership of the approximate 2% general partner interest in the Partnership and approximately 74% of the common units in the Partnership owned directly by SCW LLC and indirectly by Sisecam Chemicals as parent entity of SCW LLC.

Our Competitive Strengths

We believe that the following competitive strengths better enable us to execute our business strategies and to achieve our objective of generating and growing cash available for distribution to our unitholders:

Safety Is a Value and the Most Important Part of Our Business. We pride ourselves on our safety record, and we are continually one of the leaders in the U.S. mining industry in relation to low incident rates and workplace injuries. We maintain a rigorous safety program, which includes training, site audits and hazard identification. Sisecam Chemicals and its affiliates, our employees and all contractors who operate our assets or work at our facility are involved in our safety programs. As a direct result of this commitment, we have achieved many recognitions such as the Sentinels of Safety by the National Mining Association, The Industrial Minerals Association-North America Safety Achievement Award (Large Category) five times, most recently in September of 2021 at the Fall Industrial Minerals Association-North America Conference, Safe Sam Award by the Wyoming Mining Association two times, most recently June 2021, and the Wyoming State Mine Inspector’s Large Mine award multiple times. During the year ended December 31, 2021, our facility had one lost work day injury and three recordable injuries as reported by Mine Safety and Health Administration (“MSHA”). We also boast and support some of the best rescue teams in the country. In 2021, our Mine Rescue team competed in the Southwest Wyoming Mutual Aid competition. With 15 teams in attendance, Sisecam’s Mine Rescue team made a clean sweep of the competition including, overall champion, while also placing first in the field, team tech, bench and first aid competition. There were, however, no surface rescue contests or national mine rescue contests in 2021 due to coronavirus (“COVID-19”).

Cost Advantages of Producing Soda Ash from Trona. We believe that as a producer of soda ash from trona, we have a significant competitive advantage compared to the synthetically produced soda ash manufactured in other parts of the world. The manufacturing and processing costs for producing soda ash from trona are lower than other manufacturing techniques partly because the costs associated with procuring the materials needed for synthetic production are greater than the costs associated with mining trona for trona-based production. In addition, trona-based production consumes less energy and produces fewer undesirable by-products than synthetic production. We believe the average cost of production per short ton of soda ash (before freight and logistics costs) from trona, directly in relationship with the production methods, has a significant cost advantage when compared to synthetic production. In addition, synthetic producers of soda ash incur additional costs associated with storing or disposing of, or attempting to resell, the by-products the synthetic processes produce. Even after taking into account the higher freight costs associated with our soda ash exports, we believe we can be cost competitive with synthetic soda ash operations in most parts of the world, which are typically located closer to customers than we are. Today, we estimate that roughly 30% of global production is produced from trona-based sources, while the remainder is produced using various synthetic methods.

Synergies created from Ciner Group and Sisecam Group. The Partnership is partly owned indirectly by the Ciner Group, which is one of the largest global producers of natural soda ash derived from trona-based sources. We are one of the lowest cost producers of soda ash in the global market that has historically seen demand for soda ash exceed supply of soda ash. In addition, Şişecam Parent and its subsidiaries (the “Sisecam Group”) and the Ciner Group (collectively “Sponsors”), have international logistics experience and operating assets that assist the Partnership. As previously discussed and disclosed in the later sections of this Form 10-K, Sisecam Chemicals terminated its ANSAC membership at the end of day on December 31, 2020 to improve access to customers and gain control over placement of its sales in the international marketplace. As of January 1, 2021, Sisecam Chemicals began

Table of Contents

managing the Partnership's sales and marketing efforts for exports with the ANSAC exit being complete. With the ability to leverage our Sponsors' logistics expertise and extensive global presence and network, we have adequately replaced these net ANSAC sales.

Sisecam Group has undertaken major efforts to become an international company with its growing production power, reputable brand image, high product quality and value-creating sustainable growth approach. The company is currently one of the world's leading glass and soda ash producers with production operations located in 14 countries on four continents and more than 22,000 employees. Sisecam Group records sales in over 150 countries around the globe.

In 1969, Sisecam Group began producing soda ash and has made significant inroads to expand its investment portfolio in existing and adjacent markets ever since. Today, Sisecam Group has 2.5 million tons of soda production capacity excluding the Partnership. Sisecam Group has more than 50 years of soda production experience and nearly 85 years of industrial mining experience. It also has more than 16 years of cogeneration plant knowledge. Research and development activities conducted by Sisecam Group regarding soda and its derivatives can be utilized in the Partnership, and we believe those efforts could provide a competitive advantage for our U.S. operations. We also believe that the lean operations and continuous improvement activities of Sisecam Group can create synergies and opportunities for further optimization in the U.S.

Sisecam Group has long-standing relationships with many global customers. Sisecam Group generates 70% of its soda revenue, excluding from the Partnership, through international sales. With such extensive access to global soda markets, we believe Sisecam Group will significantly contribute to building and amplifying the sales capabilities of the Partnership. The Partnership’s customer relationships can be expanded by leveraging Sisecam Group’s existing sales networks and customer portfolios, which we believe will facilitate securing and servicing accounts, especially those in the international market.

With its extensive experience in the soda market and technical fields, along with the Sisecam Group’s significant investment history in various forms (e.g., greenfield, joint venture and sole ownership), we believe that Sisecam Group will positively contribute to the U.S. operations.

Substantial Reserve Life from Significant Reserves. Our reserve estimate, as of December 31, 2021, was prepared by Hollberg Professional Group (“HPG”), an independent mining and geological consulting firm. As of December 31, 2021, HPG estimated we had proven and probable reserves of approximately 220.0 million short tons of trona, which is equivalent to 119.1 million short tons of soda ash. Based on our current mining rate of approximately 4.0 million short tons of trona per year, we believe we have enough proven and probable trona reserves to continue mining trona using current methods in excess of 50 years. Please see Item 1, Business, “Summary of Trona Resources and Trona Reserves” and “Risk Factors-Risks Inherent in our Business and Industry - Our reserve and resource data are estimates based on assumptions that may be inaccurate and are based on existing economic and operating conditions that may change in the future, which could materially and adversely affect the quantities and value of our reserves and resources” for more information.

Certain Operational Advantages Compared to Other U.S. Trona-Based Producers. We believe we have certain operational advantages over other soda ash producers in the Green River Basin due to the operational characteristics of our facilities as described below. These advantages are manifested in our high productivity and efficiency rates.

•Location of our mining beds and high purity trona. Our mining beds are located 800 to 1,100 feet below the surface, which is significantly closer to the surface than the mining beds of other operators in the Green River Basin. The relatively shallow depth of our beds compared to other Green River Basin trona mines contributes to favorable ground conditions and improved mining efficiency. We have a competitive advantage because we can mine the trona and roof bolt simultaneously on our continuous miner equipment. In addition, the trona in our mining beds has a higher concentration of soda ash as compared to the trona mined at other locations in the Green River Basin, which is typically imbedded or mixed with greater amounts of halite and other impurities. Our trona ore is generally composed of approximately 80% to 89% pure trona.

•Advantageous facility layout. Our surface site includes a high-capacity network of ponds that we use to recapture soda ash lost in processing trona through a process we introduced in 2009 called deca rehydration (“deca”). While other producers in the Green River Basin also utilize deca rehydration, our pond complex enables us to spread deca-saturated water over a large surface area, which facilitates evaporation and access to the resulting deca. Additionally, we can transfer water from one pond to another, a process we call “de-watering,” leaving the first pond dry. De-watering enables us to use front loaders and other hauling equipment to move dry deca from that “de-watered” pond to our processing facility. Other producers in the area instead need to utilize costly dredging techniques to extract deca from their ponds, and the recovered deca is wet, and therefore requires more energy to process than dry deca. Introducing dry deca into our process has also reduced our energy consumption per short ton of soda ash produced. At our current utilization rates, we will deplete our deca supply in 2024. Please read “Risk Factors-Risks Inherent in Our Business and Industry-Our deca stockpiles will substantially deplete by 2024 and our production rates will decline approximately 200,000 short tons per year if we do not make further investments” for more information about this process.

Partly due to these operational advantages over other domestic producers, we believe we have the most efficient soda ash production facility in the Green River Basin both in terms of short tons of soda ash produced per employee and in energy

Table of Contents

consumed per short ton of soda ash produced. In 2021, we used approximately 4.0 MMBtus of energy per short ton of soda ash processed, as compared to an average of 5.5 MMBtus of energy for the other three operators in the Green River Basin according to the Wyoming Department of Environmental Quality (“WDEQ”) and our internal estimates. For the year ended December 31, 2021, we produced approximately 6,072 short tons of soda ash per employee.

Stable Domestic Customer Relationships. We have more than 70 domestic customers in industries such as flat glass, container glass, detergents, chemicals and other consumer and industrial products. We have long-term relationships with many of our customers due to our competitive pricing, reliable shipping and high-quality soda ash. For the year ended December 31, 2021, the majority of our domestic net sales were made to customers with whom we have done business for over ten years and their contracts are typically for one to three year periods. We believe that these relationships promote more stable cash flows.

Experienced Management and Workforce. Our facility has been in continuous operation for more than 50 years. We are able to build on the collective knowledge gained from our experience during this period to continually improve our operations and introduce innovative processes. In addition, many members of Sisecam Wyoming’s senior management team have more than 15 years of relevant industry experience. Our executives lead a highly productive workforce with an average tenure of approximately 12 years. We believe our institutional knowledge, coupled with the relative seniority of our workforce, engenders a strong sense of teamwork and collegiality, which has led to one of the safest and most efficient operations in the industry today.

Our Business Strategies

Our primary business objective is to generate stable cash flows through consistent growth in the production of soda ash, allowing us to make quarterly cash distributions to our common unitholders while growing our business. To achieve our objective, we intend to execute the following key business strategies:

Capitalize on Expected Growth in Demand for Soda Ash. Since 2013, we have invested just over $79.3 million for debottlenecking projects that have improved our annual production capacity by approximately 320,000 tons of soda ash per year. In connection with the CoC Transaction, we believe we have further opportunities to debottleneck our facility and are incorporating several of these in our holistic approach as we further explore whether to proceed with the Green River Expansion Project that, should we decide to proceed, we believe could increase production levels up to approximately 3.5 million tons of soda ash. We believe that as one of the leading low-cost producers of trona-based soda ash, we are well-positioned to capitalize on the expected worldwide growth of soda ash. While consumption of soda ash within the United States is expected to remain relatively flat in the near future, overall worldwide demand for soda ash, based on third-party historical production statistics and estimates, was 62.7 million metric tons (equivalent to approximately 69.1 million short tons) in 2021 and was forecasted to be 66.1 million metric tons (equivalent to approximately 72.9 million short tons) in 2022. The soda ash market is currently projected to recover from slow demand in 2020 due to the COVID-19 pandemic and grow to almost 72.0 million metric tons (equivalent to approximately 79.4 million short tons) in 2026, which represents a compounded annual growth rate of 2.8%. The ANSAC exit allowed Sisecam Chemicals to improve access to customers and gain control over placement of its sales in the international marketplace in 2021. This enhanced view of the global market allows Sisecam Chemicals to better understand supply/demand fundamentals thus allowing better decision making for its business. Sisecam Chemicals continues to optimize its distribution network leveraging strengths of existing distribution partners while expanding as our business requires in certain target areas. Please read “Customers” below for a discussion about our withdrawal from ANSAC.

Continuous Improvement Initiatives to Lower our Operating Expenses and Increase Utilization. We have been building a culture of continuous improvement. For example, several initiatives have been undertaken to reduce our overall costs to produce soda ash and increase the overall output of the facility. In 2021, the Continuous Improvement initiatives were able to transform ideas from employees into multiple projects throughout the site that resulted in an overall savings of approximately $1 million.

Leverage our Sponsors’ Capability to Build a Global Soda Ash Brand. Both of our Sponsors’ platforms include unique low cost technology, logistics assets including ports and bulk ships, and world class cost competitive production assets geographically located to serve most key markets around the world. In addition, upon Sisecam Chemicals’ termination from ANSAC (as discussed further under “Customers” below), Sisecam Chemicals is marketing soda ash directly into international markets that are currently being served by ANSAC and is utilizing the logistics expertise and extensive global presence and network that has already been established by the Sponsors.

Build a Global Soda Ash Brand. Sisecam Chemicals leveraged Ciner Group’s distribution network upon the ANSAC exit in 2021. Sisecam Chemicals adapted this model to best serve its own requirements in the target markets of our soda ash sales. Sisecam Chemicals built relationships and established its own reputation as a seller in these markets by negotiating agreements and demonstrating supply capabilities with large and midsize consumers directly selling through distribution. These direct relationships allowed Sisecam Chemicals to establish its customer base for current and future sales.

Maintain Financial Flexibility. We intend to maintain a disciplined financial policy and conservative capital structure by balancing the funding of expansion capital expenditures and acquisitions with internally generated operating cash flows and external

Table of Contents

financing sources, including commercial bank borrowings. See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources - Debt” for additional information.

Expand Operations Strategically. In addition to capacity expansions and process improvements at our current facility, we plan to grow our business through various methods as they become available to us. This would include acquisitions of other businesses that are involved in mining and processing minerals, such as soda ash, and logistics assets that could improve our efficiencies and grow our cash flows. See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Green River Expansion Project” for additional information.

We can provide no assurance that we will be able to utilize our strengths described above. For further discussion of the risks that we face, see Item 1A, “Risk Factors.”

Our Organizational Structure

The following chart depicts our ownership structure as of March 14, 2022 and approximate ownership percentages:

Our Operations

Our Green River Basin surface operations are situated on approximately 2,360 acres in Wyoming (of which, 880 acres are owned), and our mining operations consist of approximately 23,500 acres of leased and licensed subsurface mining area. Our facility is accessible by both road and rail. We use seven large continuous mining machines and fourteen underground shuttle cars in our mining operations. Our processing assets consist primarily of material sizing units, conveyors, calciners, dissolver circuits, thickener tanks, drum filters, evaporators and rotary dryers.

The following map provides an aerial overview of our surface operations:

The Green River Basin geological formation holds the largest, and one of the highest purity, known deposits of trona ore in the world. Our reserves contain trona deposits having a purity between 80% to 89% by weight, which means that insoluble impurities and water make up approximately 11% to 20% of our trona.

Our mining leases and license are located in two mining beds, designated by the U.S. Geological Survey as beds 24 and 25, at depths of 800 to 1100 feet, respectively, below the surface. Mining these beds affords us several competitive advantages. First, the

depth of our beds is shallower than other actively mined beds in the Green River Basin, which allows us to use a continuous mining technique to mine trona and roof bolt the ceiling simultaneously. In addition, mining two beds that are on top of one another allows for production efficiencies because we are able to use a single hoisting shaft to service both beds.

The following graphic shows a cross-section of the strategic areas of the Green River Basin where we mine trona:

We remove insoluble materials and other impurities by thickening and filtering the liquor. We then add activated carbon to our filters to remove organic impurities, which can cause color contamination in the final product. The resulting clear liquid is then crystallized in evaporators, producing sodium carbonate monohydrate. The crystals are then drawn off and passed through a centrifuge to remove excess water. We then dry the resulting material in a product dryer to form anhydrous sodium carbonate, or soda ash. The resulting processed soda ash is then stored in on-site storage silos to await shipment by bulk rail or truck to distributors and end customers. Our storage silos can hold up to 58,900 short tons of processed soda ash at any given time. Our facility is in good working condition and has been in service for more than 50 years.

Deca Rehydration. The evaporation stage of our trona ore processing produces a precipitate and natural by-product called deca. Deca, short for sodium carbonate decahydrate, is one part soda ash and ten parts water. Solar evaporation causes deca to crystallize and precipitate to the bottom of the four main surface ponds at our Green River Basin facility. In 2009, we implemented a process called deca rehydration, which enables us to recover soda ash from the deca-rich purged liquor as a by-product of our refining process. We capture the soda ash contained in deca by allowing the deca crystals to evaporate in the sun and separating the dehydrated crystals from the soda ash. We then blend the separated deca crystals with partially processed trona ore at the dissolving stage of our production process described above. This process enables us to reduce our waste storage needs and convert what is typically a waste product into a usable raw material. Please read “Risk Factor-Risks Inherent in Our Business and Industry-Our deca stockpiles will substantially deplete by 2024 and our production rates will decline approximately 200,000 short tons per year if we do not make further investments” for more information about this process.

Energy Consumption. We believe we have one of the most efficient mining and soda ash production surface operations in the world. During 2021, we used approximately 4.0 MMBtus of energy in the form of electricity and natural gas to produce each short ton of soda ash. In addition, we believe this to be the lowest energy consumption of any soda ash producer in North America. We and other producers of soda ash in the Green River Basin benefit from relatively low cost and stable supply of natural gas in Wyoming, which further enhances our competitive cost advantage over other regions of the world. To reduce the impact of the volatility in natural gas prices, we hedge a portion of our natural gas consumption requirements, which enables us to set the price for a portion of our forecasted natural gas purchases. During the first quarter of 2020, we completed construction of a natural gas-fired turbine co-generation facility that is capable of providing roughly one-third of our electricity and steam demands at our mine in the Green River Basin. This co-generation facility began operating in March 2020 and provided 172.6 million kWh of electricity which saved the

Table of Contents

Partnership $4.4 million in 2021 based on average purchased electricity costs and gas costs. In a normal production environment the facility is expected to provide us over 180.0 million kWh of electricity annually.

Shipping and Logistics. All of our soda ash is shipped by rail or truck from our Green River Basin operations. For the year ended December 31, 2021, we shipped over 90% of our soda ash to our customers initially via a single rail line owned and controlled by Union Pacific Railroad Company (“Union Pacific”), and our plant receives rail service exclusively from Union Pacific. Our agreement with Union Pacific expires on December 31, 2025 and there can be no assurance that it will be renewed on terms favorable to us or at all. If we do not ship at least a significant portion of our soda ash production on the Union Pacific rail line during a twelve-month period, we must pay Union Pacific a shortfall payment under the terms of our transportation agreement. For the year ended December 31, 2021, we assisted the majority of our domestic customers in arranging their freight services. During 2021, we had no shortfall payments and do not expect to make any such payments in the future. Sisecam Chemicals leases a fleet of more than 2,200 hopper cars that serve as dedicated modes of shipment to our domestic and international customers. For non ANSAC exports, we ship our soda ash on unit trains primarily to Longview, Washington for bulk shipments. For the year ended December 31, 2021, ANSAC provided logistics and support services for a portion of our export sales primarily out of Portland, Oregon and Longview, Washington. From these ports, our soda ash is loaded onto ships for delivery to ports all over the world. For domestic sales, Sisecam Chemicals provides similar services.

Customers

Our largest customer was ANSAC for the year ended December 31, 2021 and the sales to ANSAC accounted for approximately 21.1% of our net sales. The significant volume of sales to ANSAC for the year ended December 31, 2021 was primarily related to the terms of the ANSAC exit settlement agreement. No other individual customer accounted for more than 10% of our net sales.

For customers in North America, Sisecam Chemicals, on our behalf, typically enters into contracts, having terms ranging from one to three years. Under these contracts, our customers generally agree to purchase either minimum estimated volumes of soda ash or a certain percentage of their estimated soda ash requirements at a fixed price for a given calendar year. Although we do not have a “take or pay” arrangement with our customers, substantially all of our sales are made pursuant to written agreements and not through spot sales. In 2021, we had more than 70 domestic customers and in general, we have long-term relationships with the majority of our customers, meaning we have been a supplier to them for more than ten years.

Our customers, including end users to whom ANSAC makes sales overseas, consist primarily of:

•Glass manufacturing companies, which account for 50% or more of the consumption of soda ash around the world; and

•The majority of the remainder is comprised of chemical and detergent manufacturing companies.

Historically, by design and prior to Sisecam Chemicals’ exit from ANSAC, ANSAC managed most of our international sales, marketing and logistics, and as a result, was our largest customer for the years ended December 31, 2020 and 2019, accounting for 45.4% and 60.4%, respectively, of our net sales. ANSAC takes soda ash orders directly from its overseas customers and then purchases soda ash for resale from its member companies pro rata based on each member’s allocated volumes. ANSAC is the exclusive distributor for its members to the markets it serves. The ANSAC exit allowed Sisecam Chemicals to improve access to customers and gain control over placement of its sales in the international marketplace in 2021. This enhanced view of the global market allows Sisecam Chemicals to better understand supply/demand fundamentals thus allowing better decision making for its business. Sisecam Chemicals continues to optimize its distribution network leveraging strengths of existing distribution partners while expanding as our business requires in certain target areas.

Leases and License

We are party to several mining leases and one license, as noted in the table below, which give us subsurface mining rights. Some of our leases are renewable at our option upon expiration. We pay royalties to the State of Wyoming, the U.S. Bureau of Land Management and Sweetwater Royalties LLC, a subsidiary of Sweetwater Trona OpCo LLC and the successor in interest to the license with the Rock Spring Royalty Company, LLC (“RSRC”), an affiliate of Occidental Petroleum Corporation (formerly an affiliate of Anadarko Petroleum Corporation). The royalties are calculated based upon a percentage of the value of soda ash and related products sold at a certain stage in the mining process. These royalty payments may be subject to a minimum domestic production volume from our Green River Basin facility. We are also obligated to pay annual rentals to our lessors and licensor regardless of actual sales. In addition, we pay a production tax to Sweetwater County, and trona severance tax to the State of Wyoming that is calculated based on a formula that utilizes the volume of trona ore mined and the value of the soda ash produced. We have a perpetual right to continue operating under these leases and license as long as we maintain continuous mining operations and we intend to continue renewing the leases and license as has been historical practice.

licensed premises in commercial quantities; and (ii) set the production royalty rate for each sale of sodium mineral products produced from ore extracted from the licensed premises at eight percent (8%) of the net sales of such sodium mineral products. Any increase in the royalty rates we are required to pay to our lessors and licensor, or any failure by us to renew any of our leases and license, could have a material adverse impact on our results of operations, financial condition or liquidity, and, therefore, may affect our ability to distribute cash to unitholders. On December 11, 2020, the Secretary of the Interior authorized an industry-wide royalty reduction from currently set rates by establishing a 2% federal royalty rate for a period of ten years for all existing and future federal soda ash or sodium bicarbonate leases. This change by the Secretary of the Interior reduced the rates on our mineral leases with the U.S. Government from 6% to 2% as of January 1, 2021 and for the following ten years. This 4% rate reduction saved over $6.5 million in royalty fees based on our mining operations in 2021.

Trona Resources and Trona Reserves

Information concerning our mining property and estimated mineral resources and mineral reserves in this Annual Report on Form 10-K has been prepared in accordance with the requirements of subpart 1300 of Regulation S-K, which first became applicable to us for the fiscal year ended December 31, 2021. These requirements differ significantly from the previously applicable disclosure requirements of SEC Industry Guide 7. Among other differences, subpart 1300 of Regulation S-K requires us to disclose our mineral resources, in addition to our mineral reserves, at our mining property as of the end of our most recently completed fiscal year. The information that follows is derived, for the most part, from, and in some instances is an extract from the technical report summary prepared by Hollberg Professional Group (HPG) in compliance with Item 601(b)(96) and subpart 1300 of Regulation S-K. Portions of the following information are based on assumptions, qualifications and procedures, that are not fully described herein. Reference should be made to the full text of the technical report summary prepared by HPG attached as Exhibit 96.1 and incorporated herein by reference and made a part of this Report on Form 10-K. We have used the term “trona” as in “trona resources” and “trona reserves” interchangeably with “mineral.”

Hollberg Professional Group (HPG) has conducted an independent technical review of the lands held by Sisecam Chemicals referred to as the “Big Island Mine,” which is located in the area commonly referred to as the Know Sodium Lease Area (the “KSLA”) near the town of Green River, Sweetwater County. The KSLA is where trona thickness exceeds 1-meter, extends for over 300 km2, and is greater than 80% grade. The U.S. Geological Survey recognizes 25 trona beds of economic importance (at least 1 meter in thickness and 300 km2 in areal extent) within the Green River Basin. Identified in ascending order, the trona beds are numbered 1 through 25 from the oldest (stratigraphically lowest) to the youngest (stratigraphically highest). Sisecam Wyoming has approximately 23,612 acres of trona under lease made up of approximately 7,934 Federal acres, 3,079 State acres, and 12,439 private acres. Sisecam Chemicals has mineral resources and mineable reserves in the shallowest mechanically minable Trona Beds 24 and 25, at depths of 800 and 1,100 feet below the surface, respectively. See also certain maps and graphics of our property set forth under “Our Operations.”

HPG estimated the total of the Big Island Mine’s remaining leased and licensed proven and probable trona reserves as 220.0 million short tons and the total of the measured and indicated in-place trona resources inclusive of reserves as 162.3 million short tons

Table of Contents

as of December 31, 2021. The cutoff grade of greater than 75% trona and thickness greater than 6 feet is applied to estimate the trona resources based upon successful mining and processing of the lower grade trona Beds 19, 20 and 21 which were considered viable mining prospects by Texas Gulf Soda Ash (TGSA). The mineral resource inclusive of the mineral reserves is that portion of the ore body that is considered either economically viable for mining and can be converted to reserves or of economic interest but considered outside the current economic limits. This is the material considered of economic interest that has the potential to be converted to reserves. Our trona resources are categorized as “Measured mineral resources,” “Indicated mineral resources,” and “Inferred mineral resources,” which are defined as follows:

•Measured mineral resources - Mineral resources for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors, as defined in this section, in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.

• Indicated mineral resources - Mineral resources for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply the modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve. (The modifying factors are the factors that a qualified person must apply to indicated and measured mineral resources and then evaluate in order to establish the economic viability of mineral reserves. A qualified person must apply and evaluate modifying factors to convert measured and indicated mineral resources to proven and probable mineral reserves. These factors include but are not restricted to mining; processing; metallurgical; infrastructure; economic; marketing; legal; environmental compliance; plans, negotiations, or agreements with local individuals or groups; and governmental factors. The number, type and specific characteristics of the modifying factors applied will necessarily be a function of and depend upon the mineral, mine, property, or project.)

•Inferred mineral resources - Mineral resources for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project and may not be converted to a mineral reserve.

The Company has not previously disclosed estimates of measured mineral resources, indicated mineral resources or inferred mineral resources for periods prior to fiscal year 2021 for comparison.

HPG estimated proven and probable reserves of approximately 220.0 million short tons of trona, which is equivalent to 119.1 million short tons of soda ash as of December 31, 2021. Based on our current mining rate of approximately 4.0 million short tons of trona per year, we have enough proven and probable trona reserves to continue mining trona using current methods in excess of 50 years. For comparison, Sisecam Wyoming’s staff estimated proven and probable reserves of approximately 208.2 million short tons, which is equivalent to 113.4 million short tons of soda ash as of December 31, 2020. The increase of estimated proven and probable reserves of approximately 11.8 million short tons, or 5.7%, as of December 31, 2021 was primarily due to the updated staged LOM mine plan from 8-ft Isopach to 7-ft Isopach during the year ended December 31, 2021. (Isopach is a line drawn on a map connecting all points of equal thickness of a particular geologic formation.)

The mineral reserve is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. Our trona reserves are categorized as “Proven mineral reserves” and “Probable mineral reserves,” which are defined as follows:

•Proven mineral reserves - The economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource.

•Probable mineral reserves - The economically mineable part of an indicated and, in some cases, a measured mineral resource.

In determining the reserve parameters and assumptions HPG considered the following circumstances (actual results could differ from these assumptions):

•Sisecam Wyoming’s 60 year long history and economics of mining the deposit and producing soda ash;

◦The 170.1 million short tons of trona ore produced from these two beds;

•The projected long life of the mine and resulting likely changes in economics, mining, and processing methods over the projected 40-year mine life used in this technical summary. This 40-year mine life consideration is based on the specific

Table of Contents

assumptions in this technical summary, including assumptions related to projected timing and estimated cost of two-seam mining, timing of related capital expenditures and sales price projections and estimates related to future availability of deca;

•Sisecam Wyoming’s current processing facilities’ capabilities and projected future changes to these facilities.

•The economics associated with Sisecam Wyoming’s current mining equipment and history of “high grading” the thickest portions of the deposit;

•Sisecam Wyoming’s current mining equipment limitations and required future changes to these systems; and

•HPG’s knowledge of operating and managing other trona and potash mines.

In determining the reserves, HPG made certain assumptions regarding the remaining life of the Big Island Mine, including, among other things, that:

•the cost of products sold per short ton will remain consistent with Sisecam Wyoming’s cost of products sold for the five years ended December 31, 2021;

•the weighted average net sales per short ton of $188/ton will remain consistent with Sisecam Wyoming’s average net sales for the five years ended December 31, 2021;

•Sisecam Wyoming’s mining costs will remain consistent with 2021 levels with two-seam mining costs 30% higher for the two-seam production (the Partnership estimates that this increase would not impact its overall production cost by more than 1% and thus would not have a material overall impact to the Partnership’s production costs);

•Sisecam Wyoming’s processing costs will remain consistent with 2021 levels and rise in 10-years to account for lower grade material;

•Sisecam Wyoming will achieve an annual mining rate of approximately 5.0 million short tons of trona in 2024 and beyond;

•Sisecam Wyoming will process soda ash with a 90% rate of recovery, without accounting for the deca rehydration process;

•the ore to ash ratio for the stated trona reserves is 1.835:1.0 (short tons of trona run-of-mine to short tons of soda ash);

•The run-of-mine ore estimate contains dilution from the mining process;

•Sisecam Wyoming will continue to conduct only conventional mining using the room and pillar method and a non-subsidence mine design;

•Sisecam Wyoming will, in approximately 10 years, make necessary modifications to the processing facilities to allow localized mining of 75% ore grade in areas where the floor seam or insoluble disruptions have moved up into the mining horizon causing mining to be halted early due to processing facility limitations;

•Sisecam Wyoming will, within one year, conduct two-seam mining, in production panels which means to perform continuous mining on Bed 24 beneath historically mined production panels of Bed 25 with interburden thickness of approximately 35-feet;

•Sisecam Wyoming will, in approximately 20 years, make necessary equipment modifications to operate at a seam height of 7-feet, the current mining limit is 9-feet;

•Sisecam Wyoming has and will continue to have valid leases and license in place with respect to the reserves, and that these leases and license can be renewed for the life of the mine based on their extensive history of renewing leases and license;

•Sisecam Wyoming has and will continue to have the necessary permits to conduct mining operations with respect to the reserves; and

•Sisecam Wyoming will maintain the necessary tailings storage capacity to maintain tailings disposal between the mine and surface placement for the life-of-mine.

Our estimates of mineral resources and mineral reserves will change from time to time as a result of mining activities, analysis of new engineering and geologic data, modification of mining plans or mining methods and other factors. For additional information, see Item 1A, Risk Factors, “Risks Inherent in our Business and Industry” for more information regarding risks surrounding our reserves.

Internal Controls Disclosure over Trona Resources and Trona Reserves

Table of Contents

We have internal controls over the trona resources and trona reserves estimation processes that result in reasonable and reliable estimates aligned with industry practice and reporting regulations. Annually, qualified persons and other employees review the estimates of trona resources and trona reserves and the supporting documentation, and based on their review of such information recommend approval to use the trona resources and trona reserves estimates to our senior management. Our controls utilize management systems, including, but not limited to, standardized procedures, workflow processes, supervision and management approval, internal and external reviews and audits, reconciliations, and data security covering record keeping, chain of custody and data storage. Our systems also cover sample preparation and analysis, data verification, trona processing, metallurgical testing, recovery estimation, mine design and sequencing, and trona resource and reserve evaluations, with environmental, social and regulatory considerations.

These controls and other methods help to validate the reasonableness of the estimates. The effectiveness of the controls are reviewed periodically to address changes in conditions and the degree of compliance with policies and procedures. For additional information regarding the risks associated with our estimates of trona resources and reserves, see Item 1A, Risk Factors, “Risks Inherent in our Business and Industry-Our reserve and resource data are estimates based on assumptions that may be inaccurate and are based on existing economic and operating conditions that may change in the future, which could materially and adversely affect the quantities and value of our reserves and resources.”

Competition

Soda ash is a commodity natural resource traded globally with numerous producers and consumers worldwide. We compete with both North American and international soda ash producers. There are two ways to consider how we compete: (1) versus our fellow North American competitors; and (2) versus our worldwide competitors. Against our principal North American competitors, which include subsidiaries of Genesis, Solvay and Tata in the Green River Basin and Searles Valley Minerals in California, we believe we have a number of competitive advantages, including operational advantages that improve our relative cost position, life of our mineral reserves, our strong safety record, customer relationships and an experienced management team and workforce. Against our principal worldwide competitors, Solvay and various Chinese producers virtually all of their production is manufactured from synthetic processes and we believe, as a producer of soda ash from trona, we have competitive advantages when compared to synthetic producers, even after considering the fact that we generally have higher logistics costs to move the soda ash from Wyoming to regions around the world. The costs associated with procuring the materials needed for synthetic production are greater than the costs associated with mining trona. In addition, trona-based production consumes less energy and produces fewer undesirable by-products than synthetic production. See “Our Competitive Strengths” above for additional information.

Insurance

Because all of our operations are conducted at a single facility, an event such as an explosion, fire, equipment malfunction or severe weather conditions could significantly disrupt our trona mining or soda ash production operations and our ability to supply soda ash to our customers. These hazards can also cause personal injury and loss of life, pollution or environmental damage and suspension of our surface and subsurface operations. To mitigate this risk, our Sponsors and/or their affiliates maintain, on our behalf, property, casualty and business interruption insurance in amounts and with coverage and deductibles that we believe are adequate for our current operations. We regularly evaluate our policy limits and deductibles as they relate to the overall cost and scope of our insurance coverage to account for changes or growth in our business.

Environmental Matters

Our mining and processing operations, which have been conducted at our Green River Basin facility since 1962, are subject to strict regulation by federal, state, and local authorities with respect to protection of the environment. We have a rigorous compliance program to ensure that our facilities comply with environmental laws and regulations. However, we are involved from time to time in administrative and judicial proceedings and inquiries relating to environmental matters. Modifications or changes in enforcement of existing laws and regulations or the adoption of new laws and regulations in the future, particularly with respect to environmental or climate change, or changes in the operation of our business or the discovery of additional or unknown environmental contamination, could require expenditures that might be material to our results of operations or financial condition.

We summarize below certain environmental laws applicable to us that regulate discharges of substances into the air and water, the management and disposal of hazardous and non-hazardous substances and wastes, the clean-up of contaminated sites, the protection of groundwater quality and availability, plant and wildlife protection, and climate change. Our failure to comply with any of the below laws may result in the assessment of administrative, civil and criminal penalties, the imposition of clean-up and site restoration costs and liens, the issuance of injunctions to limit or cease operations, the suspension or revocation of permits and other enforcement measures that could have the effect of limiting production from our operations.

on-site sanitary landfill. The Partnership provides such assurances through a third-party surety bond (the “Surety Bond”). According to the annual recalculation and submittal, the Surety Bond amount was $41.8 million and $36.2 million at December 31, 2021 and 2020, respectively. The amount of such assurances that we are required to provide is subject to change upon annual recalculation according to Department of Environmental Quality’s Guideline 12, annual site inspection and subsequent evaluation/approval by the WDEQ’s Land Quality Division.

Clean Air Act

The federal Clean Air Act and comparable state laws restrict the emission of air pollutants from many sources. Under the Clean Air Act, our facility has been issued a Title V operating permit, which regulates emissions to air from our operations. In particular, our operations are subject to technology-based standards pursuant to the Clean Air Act’s New Source Performance Standards for Nonmetallic Mineral Processing Plants, which limit particulate matter emissions. Under associated Clean Air Act regulations our operation is also subject to Best Available Control Technology (“BACT”) requirements. In addition, our boilers are subject to technology-based standards pursuant to the Clean Air Act’s National Emission Standards for Hazardous Air Pollutants for Major Source: Industrial, Commercial and Institutional Boilers and Process Heaters, which were published in final form in November 2015. These laws and regulations may require us to obtain pre-approval for the construction or modification of certain projects or facilities expected to produce or significantly increase air emissions, obtain and strictly comply with stringent air permit requirements or utilize specific equipment or technologies to control emissions of certain pollutants.

Clean Water Act

The Federal Water Pollution Control Act, which we refer to as the Clean Water Act, and comparable state laws impose restrictions and controls regarding the discharge of pollutants into regulated waters. The discharge of pollutants into regulated waters is prohibited, except in accordance with the terms of a permit issued by the federal Environmental Protection Agency (EPA) or the state. We do not discharge any wastewater from our operations into the Green River, the nearest river system to our Green River Basin facility. However, the discharge of storm water runoff from our facility is governed by a general permit issued by the WDEQ. In particular, the general permit requires our compliance with a Storm Water Pollution Prevention Plan. We periodically monitor groundwater wells at our processing facility, most of which are proximate to our surface pond complex, for salinity, conductivity and other parameters pursuant to permits issued by the WDEQ. Permitted interceptor trenches are used to collect saline groundwater to minimize impact to the Green River.

Resource Conservation and Recovery Act

The federal Resource Conservation and Recovery Act (“RCRA”), and analogous state laws, impose requirements for the careful generation, handling, storage, treatment and disposal of nonhazardous and hazardous solid wastes. Based on the amount of hazardous waste our operations generate (less than 100 kilograms per month), we have been classified under RCRA as a conditionally exempt small quantity generator.

Comprehensive Environmental Response, Compensation, and Liability Act

The federal Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) (otherwise known as “Superfund”), and comparable state laws impose liability in connection with the release of hazardous substances into the environment. CERCLA imposes liability, without regard to fault or the legality of the original conduct, on certain classes of persons that are considered to have contributed to the release of a hazardous substance into the environment. These persons include the current and past owner or operator of the disposal site or the site where the release occurred and those who disposed or arranged for the disposal of the hazardous substances at the site where the release occurred. Under CERCLA, such persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment and for damages to natural resources. Wyoming’s Environmental Quality Act also creates the potential for liability in connection with the release of hazardous substances into the environment and has been construed to impose liability without regard to fault. We have not received notice that we are a potentially responsible party at any Superfund site.

Climate Change Legislation and Regulations

In response to findings that emissions of carbon dioxide, methane and other greenhouse gases, or GHGs, present an endangerment to public health and the environment, the EPA has adopted rules requiring the monitoring and annual reporting of GHG emissions from specified sources, including soda ash processors like us. We are monitoring and reporting GHG emissions from our operations, and we believe we are in compliance with the rules. In the past, the U.S. Congress has considered, but not enacted, legislation that would impose requirements to reduce emissions of GHGs. The State of California has enacted regulations establishing a so-called GHG “cap-and-trade” system designed to reduce GHG emissions. Our operations are not currently subject to any federal or state requirement to reduce GHG emissions. Although it is not possible at this time to predict how legislation or new regulations that may be adopted to address GHG emissions would impact our business, any such future laws and regulations limiting, or otherwise imposing a tax or financial penalty for, emissions of GHGs from our equipment and operations might be material to our results of operations or financial condition.

Mining and Workplace Safety

We believe our commitment to safety and reliability is an integral component to our fulfillment of our corporate responsibility and long term success. Through rigorous training, sharing of expertise within the Partnership, continuous monitoring and promoting a culture of excellence in operations, we continuously strive to keep our workforce, the communities in which we operate and the environment safe.

Our focus on safety is also evident in our response to the COVID-19 pandemic. We continue to closely monitor the impact of the outbreak of COVID-19 and all governmental actions in response thereto on all aspects of our business, including how it impacts our employees. We have taken strong proactive steps to keep the safety of our teams and their families as the priority. We have been executing and continue to execute on a comprehensive plan to help prevent the spread of the virus in our work locations, and it appears to be having a positive impact. This plan includes multiple layers of protection for our employees, including but not limited to, social distancing, working from home for certain employees, increased sanitation, restricted contractor and visitor access, temperature checks on employees, all contractors and third-party vendors, travel restrictions, mask wearing requirements, and daily communication with our teams. We have conducted proactive quarantining and contact tracing from the early days of this pandemic and require self-reporting of any illness, and other measures in keeping with the Centers for Disease Control and Prevention guidance and best practices. We have also prepared strong contingency plans for all our operations with specific actions based on absentee rates. While we have not utilized any such plans to date as they have not been needed, they are continuously refined in case needed. We have encouraged employees to consider getting vaccinated. We anticipate a re-opening of society when the virus plateaus and diminishes, and we have completed re-entry plans to implement as they become appropriate. We are using data to guide our actions rather than firm dates, and our teams are kept up to date on these plans. Our focus prior to and during this pandemic has been the safety of our teams and this will continue to be our priority as we scale our operations back to normal as the data guides us to do so. We continue to actively monitor and adhere to applicable local, state, federal, and international governmental guidelines and actions to better ensure the safety of our employees.

MSHA is the primary regulatory organization governing safety matters associated with trona ore mining. Accordingly, MSHA regulates underground mines and the industrial mineral processing facilities associated with trona ore mines. MSHA administers the provisions of the Federal Mine Safety and Health Act of 1977 and enforces compliance with that statute’s mandatory safety and health standards. As part of MSHA’s oversight, representatives perform at least four unannounced inspections annually for our entire facility, as well as spot check every five days in our underground facility due to our Green River Basin facility being classified as a gassy mine. For 2021, we averaged 0.55 citations per inspection day, which is below the industry average of 1.06 citations per inspection day.

We also are subject to the requirements of the U.S. Occupational Safety and Health Act (“OSHA”), and comparable state statutes that regulate the protection of the health and safety of workers. In addition, the OSHA Hazard Communication Standard requires that information be maintained about hazardous materials used or produced in operations and that this information be provided to employees, state and local government authorities and the public.

Our Green River Basin facility maintains a rigorous safety program. Sisecam Chemicals and its affiliates’ employees and contractors who operate our assets are required to complete 40 hours of initial training, as well as eight-hour annual refresher sessions. These training programs cover all of the potential site-specific hazards present at the facility. As a direct result of our commitment to safety, the Green River Basin facility has had an exceptional safety record in recent years. During the year ended December 31, 2021, our facility had one lost workday injury and three recordable injuries as reported by MSHA. During the five years ended December 31, 2021, our Green River Basin facility averaged 0.8 lost workday injuries per year and averaged 4.2 recordable injuries per year as reported by MSHA.

Human Capital

The success of our company is a direct result of our people, our values, and our culture. We believe in the potential of each individual, and we grow our potential into results through training and development.

Employees/Labor Relations

The personnel who operate our assets are employees of Sisecam Chemicals and its affiliates; and the Partnership does not have any employees. Under the joint venture agreement governing Sisecam Wyoming, Sisecam Wyoming reimburses us for the time and cost of employees who operate our assets and for support provided to Sisecam Wyoming. As of December 31, 2021 and 2020, Sisecam Chemicals and its U.S. affiliates had approximately 499 and 489 full-time employees, of which 448 and 444 are employees who operate the mine at our facility in the Green River Basin, respectively. None of these employees was covered by a collective bargaining agreement as of December 31, 2021. We consider our relations with our employees to be favorable.

In addition, under the Services Agreement, dated October 25, 2015, among the Partnership, our general partner and Sisecam Chemicals (the “Services Agreement”), Sisecam Chemicals has agreed to provide the Partnership with certain corporate, selling, marketing, and general and administrative services, in return for which the Partnership has agreed to pay Sisecam Chemicals an annual management fee and reimburse Sisecam Chemicals for certain third-party costs incurred in connection with providing such services.

Employee Development and Training

Our learning, training, and development strategy is founded upon the pillars of safety, leadership, and skills development. Each of these pillars has its own objectives, strategy, and measurements for success.

•Safety: “Safety is a value, not just a priority. It’s how we do business, it’s who we are.” We believe this, we live it, and our culture of safety training is founded on it. Every new employee participates in safety training that is specific to their work environment. Wyoming employees also participate in annual safety refresher training. Training is the vehicle we use to align our safety expectations and practices with our vision for a Zero Incident Mindset.

•Leadership: Our leaders play a critical role in building our culture. Our commitment to employee development raises employee engagement, buy-in and advances our performance. Leadership is not an assignment, a job, or a title. Leadership is a choice and we equip our leaders with tools and skills to effectively lead our employees and grow our business. These skills and tools are taught and practiced in a series of formal leadership courses that address the unique needs and challenges of our business.

•Skills Development: Skills development has 3 subcategories:

• Career Progression

• Maintenance Apprenticeships

• Education Assistance

Safety

We pride ourselves on our safety record, and we are continually one of the leaders in the U.S. mining industry in relation to low incident rates and workplace injuries. We maintain a rigorous safety program, which includes training, site audits and hazard identification. Sisecam Chemicals and its affiliates, our employees and all contractors who operate our assets or work at our facility are involved in our safety programs. As a direct result of this commitment, we have achieved many recognitions such as the Sentinels of Safety by the National Mining Association, The Industrial Minerals Association-North America Safety Achievement Award (Large Category) five times, most recently in September of 2021 at the Fall Industrial Minerals Association-North America Conference, Safe Sam Award by the Wyoming Mining Association two times, most recently June 2021, and the Wyoming State Mine Inspector’s Large Mine award multiple times. During the year ended December 31, 2021, our facility had one lost work day injury and three recordable injuries as reported by MSHA. We also boast and support some of the best rescue teams in the country. In 2021, our Mine Rescue team competed in the Southwest Wyoming Mutual Aid competition. With 15 teams in attendance, Sisecam’s Mine Rescue team made a clean sweep of the competition including, overall champion, while also placing first in the field, team tech, bench and first aid competition. There were, however, no surface rescue contests or national mine rescue contests in 2021 due to COVID-19.

ITEM 1A. Risk Factors

Limited partner interests are inherently different from the capital stock of a corporation, although many of the business risks to which we are subject are similar to those that would be faced by a corporation engaged in a similar business. You should carefully consider the following risk factors together with all of the other information included in this Report in evaluating an investment in our common units.

If any of the following risks were to occur, our business, financial condition, results of operations and our ability to distribute cash could be materially adversely affected. In that case, we might not be able to make distributions on our common units, the trading price of our common units could decline, and you could lose all or part of your investment.

Summary of Risk Factors Described Herein

Risks Inherent in our Business and Industry

•Soda ash prices have been and in the future may be volatile, which may negatively affect our financial position and operations.

•Increases in freight costs or natural gas prices or interruptions in our supply could increase our costs significantly and adversely affect our results of operations and negatively impact our competitive cost position.

•All of our operations are conducted at one facility and due to our lack of product diversification, adverse developments in the soda ash industry would adversely affect our business.

•For the year ended December 31, 2021, over 90% of our soda ash was shipped via rail, and we rely on one rail line to service our facility under a contract that expires in 2025.

•A significant portion of the demand for soda ash comes from glass manufacturers and other industrial end users whose businesses can be adversely affected by economic downturns, including due to the COVID-19 pandemic and related variants and other viruses and/or diseases.

•If the percentage of our international sales increases as a percentage of total sales, our gross margin could decrease and the average trade credit payment period of our customers could increase, which could adversely affect our financial position.

•Our deca stockpiles will be substantially depleted by 2024 and our production rates will decline by approximately 200,000 short tons per year if we do not make further investments.

•Sisecam Chemicals, on our behalf, typically enters into contracts and arrangements with our customers that have terms of one to three years, and our customers are not obligated to purchase any specific amount of soda ash from us; we are also exposed to trade credit risk in the ordinary course of business activities.

•Increased use of glass substitutes and recycled glass may affect demand for soda ash, which could adversely affect our business.

•We face intense competition, including from companies that have greater capital resources and more diversified operations.

•Our reserve data are estimates based on assumptions that may be inaccurate and are based on existing economic and operating conditions that may change in the future, which could materially and adversely affect the quantities and value of our reserves.

•A cyber-attack on or other failure of our technology infrastructure could negatively affect our operations.

•The extent to which the COVID-19 pandemic may directly or indirectly impact us is uncertain and cannot be predicted with confidence, but could have a material adverse effect on our business.

Risks Related to Our Indebtedness and Liquidity

•We may not have sufficient cash from operations following the establishment of cash reserves and payment of fees and expenses to enable us to pay any quarterly distribution on our units.

•Restrictions in the agreements governing Sisecam Wyoming’s indebtedness, including the Sisecam Wyoming Credit Facility and the Sisecam Wyoming Equipment Financing Arrangement, could limit our operations and adversely affect our business.

•Our level of indebtedness may increase, reducing our financial flexibility.

•The amount of cash we have available for distribution to holders of our units depends primarily on our cash flow and not solely on profitability, which may prevent us from making cash distributions during periods when we record net income.

Risks Inherent in an Investment in Us

•CoC Transaction could significantly and adversely affect our results of operations because of difficulties related to integration, the achievement of synergies and other challenges.

•Sisecam Chemicals, which is owned by Sisecam USA and Ciner Enterprises, indirectly owns and controls our general partner, which has sole responsibility for conducting our business and managing our operations. Our general partner and its affiliates have conflicts of interest with us and our unitholders.

•We currently do not have a majority of independent directors on the board of directors of our general partner.

•Operating performance and current and anticipated capital needs may affect the amount distributed to unitholders and our partnership agreement does not contain a requirement for us to pay distributions to our unitholders.

•Our partnership agreement restricts the remedies available to unitholders for certain actions taken by our general partner and our general partner intends to limit its liability regarding our obligations.

•Our general partner and its indirect equityholders, including Sisecam USA, and Ciner Enterprises, are not restricted in their ability to compete with us.

•Holders of our common units have limited voting rights and are not entitled to appoint our general partner or its directors.

•Even if holders of our common units are dissatisfied, they cannot initially remove our general partner without its consent.

•Our general partner interest or the control of our general partner may be transferred to a third party without unitholder consent.

•Our general partner has a limited call right that may require unitholders to sell common units at an undesirable time or price.

•We may issue additional units, including units ranking senior to common units, without unitholder approval.

•Cost reimbursements due to our general partner and its affiliates for services provided to us or on our behalf will reduce our earnings and therefore our ability to distribute cash to our unitholders.

•Your liability may not be limited if a court finds that unitholder action constitutes control of our business.

•Unitholders may have liability to repay distributions and may be personally liable for the obligations of the partnership.

•The New York Stock Exchange does not require a partnership like us to comply with certain governance requirements.

•The market price of our common units could be adversely affected by sales of substantial amounts of our common units in the public markets, including sales by our existing unitholders.

•Our unitholders who fail to furnish certain information requested by our general partner or are not eligible citizens are not entitled to receive distributions or allocations of income or loss on their common units, which will be subject to redemption.

Tax Risks to Common Unitholders

•Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, as well as our not being subject to a material amount of entity-level taxation by individual states; the tax treatment of publicly traded partnerships or an investment in our common units could be subject to potential legislative, judicial or administrative changes and differing interpretations, possibly on a retroactive basis.

•Unitholders are required to pay taxes on their respective shares of our income even if they do not receive any cash distributions.

•Tax gain or loss on the disposition of our common units could be more or less than expected.

Risks Inherent in our Business and Industry

Soda ash prices have been and in the future may be volatile, and lower soda ash prices will negatively affect our financial position and results of operations.

Our only product is soda ash, and the market price of soda ash directly affects the profitability of our operations. If the market price for soda ash declines, our revenue may decrease. Historically, the global market and, to a lesser extent, the domestic market for soda ash have been volatile, and those markets are likely to remain volatile in the future. In the past, we have reduced production to mitigate the impact of low soda ash prices. Volatility in soda ash prices can make it difficult to predict the cash we may have on hand at any given time, and a prolonged period of low soda ash prices may materially and adversely affect our financial position, liquidity (including our borrowing capacity under the $225.0 million senior secured revolving credit facility to which Sisecam Wyoming is a party (as amended, the “Sisecam Wyoming Credit Facility”)), ability to finance planned capital expenditures and results of operations.

Prices for soda ash may fluctuate in response to relatively minor changes in the supply of and demand for soda ash, market uncertainty and other factors beyond our control. These factors include, among other things:

•overall economic conditions;

•additional supply from suppliers selling into markets that we serve, including potential additional soda ash from affiliates of the Partnership;

•the level of customer demand, including in the glassmaking industry;

•changes to our customer relationships and customer sales as a result of the CoC Transaction (as defined below);

•the level of production and exports of soda ash globally;

•the level of production of materials used to produce soda ash, including trona ore or synthetic materials, globally;

•the cost of energy consumed in the production of soda ash, including the price of natural gas and electricity;

•the impact of our competitors changing their prices or increasing their capacity, exports and /or imports as applicable;

•domestic and foreign governmental relations, regulations and taxes; and

•political conditions or hostilities and unrest in regions where we export soda ash.

A substantial portion of our costs are attributable to transportation and freight costs. Increases in freight costs could increase our costs significantly and adversely affect our results of operations.

A significant amount of soda ash is sold inclusive of transportation costs, which make up a substantial portion of the total delivered cost to the customer. We transport our soda ash by rail and/or truck and, for exports, ocean vessel. As a result, our business and financial results are sensitive to increases in rail freight, trucking and ocean vessel rates. Increases in transportation costs, including increases resulting from emission control requirements, port taxes and fluctuations in the price of fuel, could make soda ash a less competitive product for glass manufacturers when compared to glass substitutes or recycled glass, or could make our soda ash less competitive than soda ash produced by competitors that have other means of transportation or are located closer to their customers. Our rail freight rates may increase year-over-year. Also, we may be unable to pass on our freight and other transportation costs in full because market prices for soda ash are generally determined by supply and demand forces.

An increase in natural gas prices, or an interruption in our natural gas supply, would negatively impact our competitive cost position when compared to other foreign and domestic soda ash producers.

We rely on natural gas as the main energy source in our soda ash production process, and therefore the cost of natural gas is a significant component of the total production cost for our soda ash. The monthly Northwest Pipeline Rocky Mountain Index natural gas settlement prices, over the past five years, have ranged between $1.29 and $6.34. For the years ended December 31, 2021, 2020, and 2019, the average monthly Northwest Pipeline Rocky Mountain Index natural gas settlement prices were $3.90, $2.07, and $2.59 per MMBtu, respectively. Furthermore, the price of natural gas could increase as a result of reduced domestic drilling and production activity. Drilling and production operations are subject to extensive federal, state, local and foreign laws and government regulations concerning, among other things, emissions of pollutants and greenhouse gases, hydraulic fracturing, and the handling of natural gas and other substances used in connection with natural gas operations, such as drilling fluids and wastewater. In addition, natural gas operations are subject to extensive federal, state and local taxation. More stringent legislation, regulation or taxation of natural gas drilling activity in the United States could directly curtail such activity or increase the cost of drilling, resulting in reduced levels of drilling activity and therefore increased natural gas prices.

Table of Contents

Any material increase in natural gas prices could adversely impact our operations by making us less competitive with other soda ash producers who do not use natural gas as a key input. If U.S. natural gas prices were to increase to a level where foreign soda ash producers were able to improve their competitive position on a unit cost basis, this would negatively affect our competitive cost position.

All of our operations are conducted at one facility. Any adverse developments at our facility could have a material adverse effect on our results of operations and therefore our ability to make cash distributions to our unitholders.

Because all of our operations are conducted at a single facility, an event such as an explosion, substantial gas leak such as methane, fire, equipment malfunction or severe weather conditions that adversely affect our facility could significantly disrupt our trona mining or soda ash production operations and our ability to supply soda ash to our customers. For example, in the fourth quarter of 2016, MSHA required us to make temporary operational modifications, which caused us to lose a significant amount of ore production. While our affiliates maintain business interruption insurance on our behalf, our policy includes a time element deductible, per occurrence, and is subject to customary limitations and exclusions. Any sustained disruption in our ability to meet our obligations under our sales agreements could have a material adverse effect on our results of operations and therefore our ability to distribute cash to unitholders.

Due to our lack of product diversification, adverse developments in the soda ash industry would adversely affect our results of operations and our ability to make cash distributions to our unitholders.

We rely exclusively on the revenues generated from the production and sale of soda ash. An adverse development in the market for soda ash in U.S. or foreign markets would have a significantly greater impact on our operations and cash available for distribution to our unitholders than it would on other companies that have a more diverse asset and product base. Some of the soda ash producers with which we compete sell a more diverse range of products to broader markets.

For the year ended December 31, 2021, over 90% of our soda ash was shipped via rail, and we rely on one rail line to service our facility under a contract that expires in 2025. Interruptions of service on this rail line could adversely affect our results of operations and our ability to make cash distributions to our unitholders.

For the year ended December 31, 2021, we shipped over 90% of our soda ash from our facility on a single rail line owned and controlled by Union Pacific. Our current transportation contract with Union Pacific expires on December 31, 2025. For the year ended December 31, 2021 and 2020, we assisted the majority of our domestic customers in arranging their freight services. Rail operations are subject to various risks that may result in a delay or lack of service at our facility, including mechanical problems, extreme weather conditions, work stoppages, labor strikes, terrorist attacks and operating hazards. Moreover, if Union Pacific’s financial condition were adversely affected, it could decide to cease or suspend service to our facility. If we are unable to ship soda ash by rail, it would be impracticable to ship all of our soda ash by truck and it would be cost-prohibitive to construct a rail connection to the closest alternative rail line that is approximately 135 miles from our facility. Any delay or failure in the rail services on which we rely could have a material adverse effect on our financial condition and results of operations and our ability to make distributions to our unitholders. Moreover, if we do not ship at least a significant portion of our soda ash production on the Union Pacific rail line during a twelve-month period, we must pay Union Pacific a shortfall payment under the terms of our transportation agreement. During the years ended December 31, 2021 and 2020, we had no shortfall payments under the transportation agreement.

A significant portion of the demand for soda ash comes from glass manufacturers and other industrial end users whose businesses can be adversely affected by economic downturns.

A significant portion of the demand for soda ash comes from glass manufacturers and other industrial customers. Companies that operate in the industries that glass manufacturers serve, including the automotive, construction and glass container industries, may experience significant fluctuations in demand for their own end products because of economic conditions, changes in consumer demand, or increases in raw material and energy costs. In addition, many large end users of soda ash depend upon the availability of credit on favorable terms to make purchases of raw materials such as soda ash. As interest rates increase or if our customers’ creditworthiness deteriorates, this credit may be expensive or difficult to obtain. If these customers cannot obtain credit on favorable terms, they may be forced to reduce their purchases of soda ash. These and other factors may lead some customers to purchase less under or seek renegotiation or cancellation of their existing arrangements with us, which could have a material adverse effect on our results of operations and our ability to distribute cash to unitholders.

If the percentage of our international sales increases as a percentage of total sales, our gross margin could decrease and the average trade credit payment period of our customers could increase, which could adversely affect our financial position and our ability to distribute cash to our unitholders.

For the year ended December 31, 2021, our international sales of soda ash as a percentage of total sales was 48.8%. Our gross margin for international sales has historically been lower than our gross margin for domestic sales most of the time because

Table of Contents

our average price of soda ash sold internationally has historically been lower than our average price of soda ash sold domestically. Lower margins could adversely affect our financial position and our ability to distribute cash to our unitholders.

We typically receive payment for our domestic sales quicker than we receive payment for our international sales. Therefore, an increase in our international sales and a decrease in domestic sales would extend the average time period for our receipt of payment for our soda ash, which could expose us to greater credit risk from our customers, increase our working capital requirements and negatively affect the amount of cash available for distribution to our unitholders.

Our deca stockpiles will be substantially depleted by 2024 and our production rates will decline by approximately 200,000 short tons per year if we do not make further investments.

In 2024, our deca stockpiles will be substantially depleted. In connection with the CoC Transaction, we are evaluating whether and when to pursue a potential Green River Expansion Project at the site that could offset this decline as well as provide additional soda ash production above our current rates. We cannot guarantee that any such investments will be executed successfully, in a timely manner or if at all to enable us to maintain our current rates of production.

Sisecam Chemicals, on our behalf, typically enters into contracts and arrangements with our customers that have terms of one to three years, and our customers are not obligated to purchase any specific amount of soda ash from us.

The terms of our customer contracts vary, including by geography. Most of our domestic contracts have terms of one to three years. Our international contracts are typically for one year or less. Moreover, some of our customer contracts are not exclusive dealing and almost none are take-or-pay arrangements. Additionally, we may lose a customer for any number of reasons, including as a result of a merger or acquisition, the selection of another provider of soda ash, business failure or bankruptcy of the customer or dissatisfaction with our performance or pricing. Loss of any of our major customers could adversely affect our business, results of operations and cash flow.

Increased use of glass substitutes and recycled glass may affect demand for soda ash, which could adversely affect our results of operations.

Increased use of glass substitutes or recycled glass in the container industry could have a material adverse effect on our results of operations and financial condition. Container glass production is one of the principal end markets for soda ash. Competition from increased use of glass substitutes, such as plastic and recycled glass, has had a negative effect on demand for soda ash. Demand for soda ash by the U.S. glass container industry has generally declined over the last ten years. However, international demand for glass containers is growing at close to World Gross Domestic Product rate. We believe that the use of containers made with alternative materials such as plastic and aluminum will continue to negatively affect the growth in domestic demand for soda ash in the U.S.

We are exposed to trade credit risk in the ordinary course of our business activities.

We extend credit to our customers as a normal part of our business and as such are subject to the credit risk of our customers, including the risk of loss resulting from nonpayment or nonperformance. Standard industry contract terms are net 30 days from the date of shipment for domestic U.S. customers and 120-150 days from the date of shipment for international customers. We have experienced nonperformance by our customers and counterparties in the past, and we may take reserves for accounts more than 90 days past due. Some of our customers and counterparties may be highly leveraged and subject to their own operating and regulatory risks. Our credit procedures and policies do not eliminate customer credit risk of existing or future customers. In addition, even if our procedures work as designed, our customers may experience unanticipated deterioration of their creditworthiness. Material nonpayment or nonperformance by our customers could have a material adverse effect on our financial condition and results of operations and on our ability to distribute cash to our unitholders.

We face intense competition, including from companies that have capital resources greater than ours and that have more diversified operations.

We face competition from a number of soda ash producers in the United States, Europe and Asia, some of which have greater market share and greater financial, production and other resources than we do. Some of our competitors are diversified global corporations that have many lines of business. For example, our affiliates are in the early stages of entering into agreements and evaluating opportunities that may result in producing new soda ash from one or more separate facilities in the U.S. in the future which may increase competition if developed. Some of our competitors have greater capital resources and may be in a better position to withstand a long-term deterioration in the soda ash market. Other competitors, even if smaller in size, may have greater experience and stronger relationships in their local markets. Competitive pressures could make it more difficult for us to retain our existing customers and attract new customers, which could have a material adverse effect on our business, financial condition, results of operations and ability to distribute cash to our unitholders. Competition could also intensify the negative impact of factors that decrease demand for soda ash in the markets we serve, such as adverse economic conditions, weather, higher fuel costs and taxes or other governmental or regulatory actions that directly or indirectly increase the cost or limit the use of soda ash. In

addition, China is the largest producer of synthetic soda ash in the world and historically has exported only a small percentage of its production. If Chinese producers, which we believe are supported by government subsidies, and other producers were to begin producing significantly more quantities of soda ash than are produced today then the supply of soda ash in the global market could materially increase and put downward pressure on pricing.

Unfavorable economic conditions may reduce demand for our products, which could adversely affect our results of operations.

Worldwide soda ash demand correlates to global economic growth. Worsening economic conditions or factors that negatively affect the economic health of the United States and other parts of the world into which we sell soda ash could reduce our revenues and adversely affect our results of operations. For example, during the COVID-19 pandemic in 2020, global economic growth and soda ash demand slowed and we experienced adverse results that resulted in our board of directors approving a suspension of our quarterly distribution for each of the quarters ended June 30, 2020, September 30, 2020, December 31, 2020, March 31, 2021, and June 30, 2021. We believe that deterioration of economic conditions or a prolonged period of economic weakness would have an adverse impact on our results of operations, business and financial condition, as well as our ability to distribute cash to our unitholders.

Our reserve and resource data are estimates based on assumptions that may be inaccurate and are based on existing economic and operating conditions that may change in the future, which could materially and adversely affect the quantities and value of our reserves and resources.

Our reserve and resource estimates may vary substantially from the actual amounts of minerals we are able to recover economically from our reserves. There are numerous uncertainties inherent in estimating quantities of reserves and resources, including many factors beyond our control. Estimates of reserves and resources necessarily depend upon a number of variables and assumptions, any one of which may, if incorrect, result in an estimate that varies considerably from actual results. These factors and assumptions relate to, among other aspects:

•future prices of soda ash, mining and production costs, capital expenditures and transportation costs;

•future mining technology and processes;

•the effects of regulation by governmental agencies; and

•geologic and mining conditions, which may not be identified by available exploration data and may differ from our experiences in areas where we currently mine.

Please read Item 1, “Business-Summary of Trona Resources and Trona Reserves” for more information including pertinent additional assumptions regarding our reserve estimates in this Report. Actual production, revenue and expenditures with respect to our reserves will likely vary from our estimates, and these variations may be material.

A cyber-attack on or other failure of our technology infrastructure could affect our business and assets, and have a material adverse effect on our financial condition, results of operations and cash flows.

We are becoming increasingly dependent on our technology infrastructure and certain critical information systems which process, transmit and store electronic information, including information we use to safely and effectively operate our respective assets and business. These information systems include data network and telecommunications, internet access, our websites, and various computer hardware equipment and software applications, including those that are critical to the safe operation of our soda ash production facility and other facilities and assets that we utilize. We have invested, and expect to continue to invest, significant time, manpower and capital in our technology infrastructure and information systems. These information systems are subject to damage or interruption from a number of potential sources including natural disasters, software viruses or other malware, power failures, cybersecurity threats to gain unauthorized access to sensitive information, cyber-attacks, which may render data systems unusable, and physical threats to the security of our assets and infrastructure or third-party facilities and infrastructure.

Additionally, our business is highly dependent on financial, accounting and other data processing systems. We process a large number of transactions on a daily basis and rely upon the proper functioning of computer systems. Furthermore, we rely on information systems across our operations, including the management of supply chain and various other processes and transactions. As a result, a disruption on any information systems at our soda ash production facility or other facilities and assets that we utilize, may cause disruptions to our operations and have a material adverse effect on our financial condition, results of operations and cash flows.

The potential for such security threats or system failures has subjected our operations to increased risks that could have a material adverse effect on our business. To the extent that these information systems are under our control, we have implemented measures such as virus protection software, vulnerability scans, 24/7 monitoring of network services and operating enterprise resource planning, payroll, and logistics systems in the cloud. However, security measures for information systems cannot be

Table of Contents

guaranteed to be failsafe and implemented measures may not prevent delays or other complications that could arise from an information systems failure. If a key system was hacked or otherwise interfered with by an unauthorized user, or was to fail or experience unscheduled downtime for any reason, even if only for a short period, or any compromise of our data security or our inability to use or access these information systems at critical points in time could unfavorably impact the timely and efficient operation of our business, damage our reputation and subject us to additional costs and liabilities.

Cyber-attacks against us or others in our industry could result in additional regulations, and U.S. government warnings have indicated that infrastructure assets may be specifically targeted by certain groups. These attacks include, without limitation, malicious software, ransomware, attempts to gain unauthorized access to data, and other electronic security breaches. These attacks may be perpetrated by state-sponsored groups, “hacktivists”, criminal organizations or private individuals (including employee malfeasance). Current efforts by the federal government, such as the Strengthening the Cybersecurity of Federal Networks and Critical Infrastructure executive order, and any potential future regulations could lead to increased regulatory compliance costs, insurance coverage cost or capital expenditures. We cannot predict the potential impact to our business, the soda ash production industry or certain infrastructure facilities, assets and services upon which we rely resulting from additional regulations.

Further, our business interruption insurance may not compensate us adequately for losses that may occur. We do not carry insurance specifically for cybersecurity events; however, certain of our insurance policies may allow for coverage for a cyber-event resulting in ensuing property damage from an otherwise insured peril. If we were to incur a significant liability for which we were not fully insured, it could have a material adverse effect on our financial position, results of operations and cash flows. In addition, the proceeds of any such insurance may not be paid in a timely manner and may be insufficient if such an event were to occur.

Our business may continue to be adversely affected by the COVID-19 outbreak or the outbreak of other contagious diseases.

Public health epidemics, pandemics or outbreaks of contagious diseases could adversely impact our business. For example, the impact of the ongoing COVID-19 pandemic (including the Delta and Omicron variants), continue to cause certain disruptions and volatility to the economy throughout the world, including the United States and markets to which our products have historically been exported, affecting changes in consumer behavior, pandemic fears and market downturns, and restrictions on business and individual activities. There have been extraordinary actions taken by international, federal, state, and local public health and governmental authorities to contain and combat the outbreak and spread of COVID-19 in regions throughout the world, including travel bans, quarantines, “stay-at-home” orders, and similar mandates for many individuals to substantially restrict daily activities and for many businesses to curtail or cease normal operations.

The extent to which COVID-19 will continue to impact our future financial condition, results of operations, liquidity and ability to make distributions to unitholders will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak, new information that may emerge concerning the severity of the COVID-19 outbreak and government mandated actions, requests or orders taken to contain the spread of COVID-19 or treat its impact, among others. In particular, the outbreak and any preventative or protective actions that governments, the Partnership or its affiliates or customers, or third parties upon which we rely for essential supplies or logistics services may take in respect of the COVID-19 outbreak, may result in a period of operational disruption and a potential reduction in the availability of our workforce. COVID-19 could also have a material impact across a variety of our customers and customer segments, which could have a negative impact on the demand for our products.

In addition, the COVID-19 outbreak may continue to impact our ability to timely develop and execute, or to ultimately realize the expected benefits from, our potential Green River Expansion Project (if undertaken), due to, among other things, a decline in the worldwide demand for soda ash, the cost or availability of debt financing or reduced cash flows from our operations to fund the project or any inability to procure the services, materials and equipment necessary to complete the project. Further, a prolonged period of disruption in worldwide economic and financial markets could constrain our available sources of liquidity to fund our operations, negatively impact our ability to service our financial obligations to lenders under our credit facilities and financing arrangements and pay distributions to our unitholders.

Any resulting financial impacts to the Partnership as a result of COVID-19, or other similar outbreaks of contagious diseases, including impacts to our results of operations, liquidity and ability to make distributions to our unitholders, are not reasonably estimable and cannot be predicted with confidence, but could be material.

If we are not able to renew our leases and licenses, it will have a material adverse effect on us. Under the terms of our subsurface mining leases, we are required to make minimum royalty payments or annual rentals, and the royalty rates we are required to pay may change with little or no notice to us.

All of our reserves are held under leases with the State of Wyoming and the U.S. Bureau of Land Management and a license with Sweetwater Royalties LLC. As of December 31, 2021, none of our leases covering our acreage expire prior to 2027.

Table of Contents

If we are not able to renew our leases, it will have a material adverse effect on our results of operations and cash available for distribution to unitholders. Each of those leases and the license requires that minimum royalties or annual rentals be paid regardless of production levels. If our operations do not meet production goals, then it could have an adverse effect on our ability to pay cash distributions due to the ongoing requirement to pay minimum royalty payments despite a lack of production and the corresponding net sales.

The royalty rates we pay to our lessors may change upon our renewal of such leases. Any increase in the royalty rates we are required to pay to our lessors, or any failure by us to renew any of our leases, could have a material adverse impact on our results of operations, financial condition, or liquidity, and, therefore, may affect our ability to distribute cash to unitholders.

Defects in title or loss of any leasehold interests in our properties could limit our ability to conduct mining operations on these properties or result in significant unanticipated costs.

All of our trona reserves are leased or licensed. A title defect in our leased, licensed or owned property or the loss of any lease or license upon expiration of its term, upon a default or otherwise could adversely affect our ability to mine the associated reserves and/or process the trona that we mine. In some cases, we rely on title information or representations and warranties provided by our lessors, licensor or grantor. We cannot rely on any such representations or warranties with respect to the surface land on which our facility is located because we acquired the surface land in 1991 by quitclaim deed. We have no title insurance for our interests in this property. Any challenge to our title or leasehold interests could delay our operations and could ultimately result in the loss of some or all of our interest in the property. From time to time we also may be in default with respect to leases or the license for properties on which we have mining operations. In such events, we may have to close down or alter significantly the sequence of such mining operations, which may adversely affect our future soda ash production and future revenues. If we mine on property that we do not own, lease or license, we could incur liability for such mining and be subject to regulatory sanction and penalties. Also, in any such case, the investigation and resolution of title issues would divert management’s time from our business, and our results of operations could be adversely affected. As a result, our results of operations, business and financial condition, as well as our ability to pay distributions to our unitholders may be materially adversely affected.

We may not achieve the acquisition component of our growth strategy.

Acquisitions are a component of our growth strategy. We can offer no assurance that we will be able to identify any acquisition opportunities, that we will be able to grow our business through acquisitions, or that any assets or business we acquire will perform in accordance with our expectations or that our assessment concerning the value, strengths and weaknesses of assets or business acquired will prove to be correct. We have not made any acquisitions in the past, and there are currently a limited number of producers in North America with businesses similar to ours and potentially legal and regulatory hurdles, such as extensive evaluation under antitrust laws to determine whether the acquisition would be permissible. In connection with future acquisitions, if any, we may incur debt and contingent liabilities, increased interest expense and amortization expense and significant charges relative to integration costs. In addition, our financial condition and results of operations would be adversely affected if we overpay for acquisitions.

Acquisitions involve a number of special risks, including:

•unforeseen difficulties extending internal control over financial reporting and performing the required assessment at the newly acquired business or assets;

•potential adverse short-term effects on operating results through increased costs or otherwise;

•diversion of management’s attention and failure to recruit new, and retain existing, key personnel of the acquired business or assets;

•failure to implement infrastructure, logistics and systems integration successfully; and

•the risks inherent in the systems of the acquired business and risks associated with unanticipated events or liabilities, any of which could have a material adverse effect on our business, financial condition and results of operations.

Mining development, exploration and processing operations pose numerous hazards and uncertainties that may negatively affect our business.

Mining and processing operations involve many hazards and uncertainties, including, among other things:

•seismic activity;

•ground failures;

•industrial accidents;

Table of Contents

•environmental contamination or leakage, including gas leaks;

•fires and explosions;

•unusual and unexpected rock formations or water conditions;

•flooding and periodic interruptions due to inclement or hazardous weather conditions or other acts of nature; and

•mechanical equipment failure and facility performance problems.

These occurrences could damage or destroy our properties or production facilities, or result in personal injury or wrongful death claims, environmental damage to our properties or the properties of others, delays in, or prohibitions on, mining or processing, increased production costs, asset write downs, monetary losses and legal liability, which could have an adverse effect on our results of operations and financial condition. In particular, underground mining and related processing activities present inherent risks of injury to persons and damage to equipment. Our insurance policies provide limited coverage for some of these risks but will not fully cover these risks. Please read “Risk Factors—Risks Inherent in our Business and Industry—Our business is subject to inherent risk, including risk relating to natural disasters, and our insurance coverage for such risks may not be adequate or available to us. If an accident or event occurs that is not fully insured, it could materially affect our business.” Significant mine accidents could occur, potentially resulting in a mine shutdown or leading to liabilities, which could have a material adverse effect on our results of operations, financial condition and cash flows.

We may be unable to obtain, maintain or renew permits necessary for our operations, which could impair our ability to conduct our operations and limit our ability to make distributions to unitholders.

Our facility and operations require us to obtain a number of permits that impose strict regulations on various environmental and operational matters in connection with mining trona ore and producing soda ash. These include permits issued by various federal, state and local agencies and regulatory bodies. The permitting rules, and the interpretations of these rules, are complex, change frequently and are subject to discretionary interpretations by our regulators, all of which may make compliance difficult or impractical and may impair our existing operations or the development of future facilities. The public, including non-governmental organizations, environmental groups and individuals, have certain statutory rights to comment upon and submit objections to requested permits and environmental impact statements prepared in connection with applicable regulations and otherwise engage in the permitting process, including bringing citizen’s lawsuits to challenge the issuance or renewal of permits, the validity of environmental impact statements or the performance of mining activities. If permits are not issued or renewed in a timely fashion or at all or are conditioned in a manner that restricts our ability to conduct our operations economically, our cash flows may decline, which could limit our ability to distribute cash to unitholders.

Equipment upgrades, equipment failures and deterioration of assets may lead to production curtailments, shutdowns or additional expenditures.

Our operations depend upon critical equipment that require scheduled upgrades and maintenance and may suffer unanticipated breakdowns or failures. As a result, our mining operations and processing may be interrupted or curtailed, which could have a material adverse effect on our results of operations.

As our mine ages and we deplete our trona reserves, in order to maintain current production rates in the near term, we expect to need to utilize a two seam mining technique, which could increase our mining cost slightly for the relevant portion of the production. In addition, our maintenance capital expenditures do not include actual or estimated capital expenditures for replacement of our trona reserves.

In addition, assets critical to our trona ore mining and soda ash production operations may deteriorate due to wear and tear or otherwise sooner than we currently estimate. Such deterioration may result in additional maintenance spending and additional capital expenditures. If these assets do not generate the amount of future cash flows that we expect, and we are not able to procure replacement assets in an economically feasible manner, our future results of operations may be materially and adversely affected.

If any of the equipment on which we depend were severely damaged or were destroyed by fire, abnormal wear and tear, flooding, or otherwise, we may be unable to replace or repair it in a timely manner or at a reasonable cost, which would impact our ability to produce and ship soda ash, which would have a material adverse effect on our results of operations, financial condition and our ability to distribute cash to our unitholders.

We may record impairment charges on our assets, including our reserves, that would adversely impact our results of operations and financial condition.

We are required to perform impairment tests on our assets, including our trona reserves, whenever events or changes in circumstances modify the estimated useful life of or estimated future cash flows from an asset that would indicate that the carrying

Table of Contents

amount of such asset may not be recoverable or whenever management’s plans change with respect to such asset. An impairment in one period may not be reversed in a later period even if prices increase. If we are required to recognize impairment charges in the future, our results of operations and financial condition may be materially and adversely affected.

A shortage of skilled workers could reduce our labor productivity and increase our costs, which could negatively affect our business.

Our mining and processing operations require personnel with specialized skills and experience. Our ability to be productive and profitable will depend upon our ability to employ and retain skilled workers. If we experience shortages of skilled workers in the future, our labor costs and overall productivity could be materially and adversely affected. If our labor costs increase or if we experience materially increased health and benefits costs, our results of operations could be materially and adversely affected.

We also depend on good relationships with our workforce generally. Any disruption in our relationships with our personnel, including as a result of potential union organizing activities, work actions or other labor issues, could substantially affect our operations and results.

Severe weather conditions could have a material adverse impact on our business.

Our business could be materially adversely affected by severe weather conditions. Severe weather conditions may affect our mining and processing operations by resulting in weather-related damage to our facility and equipment or impact our ability to transport soda ash from our facility. In addition, severe weather conditions could hinder our operations by causing us to halt or delay our operations, which could have a material adverse effect on our results of operations and financial condition.

Our business is subject to inherent risk, including risk relating to natural disasters, and our insurance coverage for such risks may not be adequate or available to us. If an accident or event occurs that is not fully insured, it could materially affect our business.

We are covered by insurance policies maintained by our affiliates on our behalf. These insurance policies provide limited coverage for some, but not all, of the potential risks and liabilities associated with our business. For some risks, we do not maintain insurance policies if we believe the cost of available insurance is excessive relative to the risks presented. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially, and certain types of insurance may become unavailable or available only for reduced amounts of coverage. As a result, we may not be able to renew applicable existing insurance policies or procure other desirable insurance on commercially reasonable terms, if at all. In addition, we cannot insure against certain environmental, safety and pollution risks. Even where insurance coverage applies, insurers may contest their obligations to make payments. Our insurance coverage may not be adequate to cover us against losses we incur, and coverage under these policies may be depleted or may not be available to us to the extent that we otherwise exhaust its coverage limits. Our results of operations, and therefore our ability to distribute cash to unitholders, could be materially and adversely affected by losses and liabilities from uninsured or under-insured events, as well as by delays in the payment of insurance proceeds or the failure by insurers to make payments.

We also may incur costs and liabilities resulting from claims for damages to property or injury to persons arising from our operations. We must compensate employees for work-related injuries. If we do not make adequate provision for our workers’ compensation liabilities, such claims could harm our future operating results. If we are required to pay for these fines, costs and liabilities, our financial condition, results of operations, and therefore our ability to distribute cash to unitholders, could be adversely affected.

We may be subject to litigation, the disposition of which could have a material adverse effect on our results of operations.

The nature of our operations exposes us to possible litigation claims, including disputes with customers and providers of shipping services. Some of the lawsuits may seek fines or penalties and damages in large amounts or seek to restrict our business activities. Because of the uncertain nature of litigation and coverage decisions, we cannot predict the outcome of these matters or whether insurance claims may mitigate any damages to us. Litigation is very costly, and the costs associated with prosecuting and defending litigation matters could have a material adverse effect on our results of operations.

Expansion or improvement of our existing facilities may not result in revenue increases and will be subject to regulatory, environmental, political, legal and economic risks, which could adversely affect our results of operations and financial condition.

One of the ways we may grow our business is through the expansion or improvement of our existing facility. The construction of additions or modifications to our existing facility involve numerous regulatory, environmental, political, legal and economic uncertainties that are beyond our control. Such expansion or improvement projects may also require the expenditure of significant amounts of capital, and financing may not be available on economically acceptable terms or at all. If we undertake

Table of Contents

expansion or improvement projects, including if we determine to proceed with the Green River Expansion Project, or undertake other or additional expansion or improvement projects, any such projects may not be completed on schedule, at the budgeted cost, or at all. Moreover, our revenue may not increase immediately upon the expenditure of funds on a particular project. As a result, we may not be able to realize our expected investment return, which could adversely affect our results of operations and financial condition.

We conduct our operations through a joint venture, which subjects us to additional risks that could have a material adverse effect on our financial condition and results of operations.

The Partnership is a holding company that conducts its primary operations through Sisecam Wyoming, a joint venture with an affiliate of NRP. The amount of cash Sisecam Wyoming can distribute to the Partnership depends primarily on cash flows generated from Sisecam Wyoming’s operations, which may fluctuate depending on, among other things, revenues it receives and costs it incurs, including for capital expenditure projects undertaken by Sisecam Wyoming.

We may also enter into other joint venture arrangements with third parties in the future. NRP has, and these third parties may have, obligations that are important to the success of the joint venture, such as the obligation to pay their share of capital and other costs of the joint venture. The performance of these third-party obligations, including the ability of our joint venture partner in Sisecam Wyoming, to satisfy their respective obligations, is outside our control. If these parties do not satisfy their obligations under the arrangement, our business may be adversely affected.

Our joint venture arrangement may involve risks not otherwise present without such partner, including, for example:

•our joint venture partner shares certain blocking rights over transactions between Sisecam Wyoming and its affiliates, including us and potential arrangements between us and Sisecam Chemicals, Ciner Enterprises and/or Sisecam USA and their respective affiliates, including Sisecam Chemicals’ ability to market our soda ash directly into international markets;

•our joint venture partner may propose changes to our capital expenditure programs;

•our joint venture partner may take actions contrary to our instructions or requests or contrary to our policies or objectives;

•although we control Sisecam Wyoming, we owe contractual duties to Sisecam Wyoming and its other owners, which may conflict with our interests and the interests of our unitholders; and

•disputes between us and our joint venture partner may result in delays, litigation or operational impasses.

The risks described above or any failure to continue our joint venture or to resolve disagreements with our joint venture partner could adversely affect our ability to transact the business that is the subject of such joint venture, which would, in turn, negatively affect our financial condition, results of operations and ability to distribute cash to our unitholders.

We are subject to stringent environmental laws and regulations that may expose us to significant costs and liabilities.

Our operations are subject to stringent and complex federal, state and local environmental laws and regulations that govern the discharge of materials into the environment or otherwise relate to environmental protection. Examples of these laws include:

•the federal Clean Air Act and analogous state laws that impose obligations related to air emissions;

•the CERCLA or the Superfund law, and analogous state laws that regulate the cleanup of hazardous substances that may be or have been released at properties currently or previously owned or operated by us or at locations to which our wastes are or have been transported for disposal;

•the federal Water Pollution Control Act, or the Clean Water Act, and analogous state laws that regulate discharges from our facilities into state and federal waters, including wetlands and the Green River;

•the RCRA, and analogous state laws that impose requirements for the storage, treatment and disposal of solid and hazardous waste from our facilities;

•the Endangered Species Act, or ESA; and

•the Toxic Substances Control Act, or TSCA, and analogous state laws that impose requirements on the use, storage and disposal of various chemicals and chemical substances at our facility.

These laws and regulations may impose numerous obligations that are applicable to our operations, including the acquisition of permits to conduct regulated activities, the incurrence of capital or operating expenditures to limit or prevent releases of materials from our facility, and the imposition of substantial liabilities and remedial obligations for pollution resulting from our

Table of Contents

operations. Numerous governmental authorities, such as the U.S. Environmental Protection Agency, or the EPA, and analogous state agencies, have the power to enforce compliance with these laws and regulations and the permits issued under them, oftentimes requiring difficult and costly corrective actions. Failure to comply with these laws, regulations and permits may result in the assessment of administrative, civil and criminal penalties, the imposition of remedial obligations and the issuance of injunctions limiting or preventing some or all of our operations. In addition, we may experience a delay in obtaining or be unable to obtain required permits or regulatory authorizations, which may cause us to lose potential and current customers, interrupt our operations and limit our growth and revenue. In addition, future changes in environmental or other laws may result in additional compliance expenditures that have not been pre-funded and which could adversely affect our business and results of operations and our ability to make cash distributions to our unitholders.

There is a risk that we may incur costs and liabilities in connection with our operations due to historical industry operations and waste disposal practices, our handling of wastes and potential emissions and discharges related to our operations. Private parties, including the owners of the properties on which we operate, may have the right to pursue legal actions to require remediation of contamination or enforce compliance with environmental requirements as well as to seek damages for personal injury or property damage. For example, an accidental release from our facility could subject us to substantial liabilities arising from environmental cleanup and restoration costs, claims made by neighboring landowners and other third parties for personal injury and property damage and fines or penalties for related violations of environmental laws or regulations. In addition, changes in environmental laws occur frequently, and any such changes that result in more stringent and costly waste handling, storage, transport, disposal or remediation requirements could have a material adverse effect on our operations or financial position. We may not be able to recover all or any of these costs from insurance. Please read Item 1, “Business—Environmental Matters” for more information.

The adoption of climate change legislation or enhanced scrutiny on environmental matters at the global, federal, state or local level could result in increased operating costs and reduced demand for the soda ash we produce.

Many nations have agreed to limit emissions of “greenhouse gases,” or GHGs, pursuant to the United Nations Framework Convention on Climate Change, also known as the “Kyoto Protocol.” Methane, a primary component of natural gas, and carbon dioxide, a by-product of the burning of coal, oil, natural gas and refined petroleum products, are GHGs regulated by the Kyoto Protocol. The United States signed, but did not ratify, the Kyoto Protocol. In August 2015, the Obama administration announced the Clean Power Plan (the “CPP”), which sets limits on GHG emissions from power plants. Further, in December 2015, the United States was one of 195 countries to sign the so-called Paris Agreement, committing to work towards addressing climate change and agreeing to a monitoring and review process for greenhouse gas emissions. The Paris Agreement came into effect in November 2016. Although the United States withdrew from the Paris Agreement in November 2020, the United States officially rejoined the Paris Agreement in February 2021 following the change in Presidential administrations and may in the future choose to join other international agreements targeting greenhouse gas emissions. In addition, in January 2021, President Biden issued an executive order directing all federal agencies to review and take action to address any federal regulations, orders, guidance documents, policies, and any similar agency actions promulgated during the prior administration that may be inconsistent with the current administration’s policies and to confront the climate crisis. President Biden also issued an executive order solely targeting climate change.

The U.S. Congress has from time to time considered adopting legislation to reduce emissions of GHGs, and almost one-half of the states have already taken legal measures to reduce emissions of GHGs, primarily through the planned development of GHG emission inventories and/or regional GHG “cap and trade” programs. Although the U.S. Congress has not adopted such legislation at this time, many states continue to pursue regulations to reduce GHG emissions. Most of these cap and trade programs work by requiring major sources of emissions, such as electric power plants, or major producers of fuels, such as refineries and natural gas processing plants, to acquire and surrender emission allowances corresponding with their annual emissions of GHGs. These programs work by reducing the number of allowances available for purchase each year until the overall GHG emission reduction goal is achieved. As the number of GHG emission allowances declines each year, the cost or value of allowances is expected to escalate significantly. Restrictions on GHG emissions that may be imposed in various states could adversely affect the soda ash industry.

In addition, there has been public discussion that climate change may be associated with extreme weather conditions, such as more intense hurricanes, thunderstorms, tornados and snow or ice storms, as well as rising sea levels. Another possible consequence of climate change is increased volatility in seasonal temperatures. Some studies indicate that climate change could cause some areas to experience temperatures substantially colder than their historical averages. Extreme weather conditions can interfere with our production and increase our costs, and damage resulting from extreme weather may not be fully insured. However, at this time, we are unable to determine the extent to which climate change may lead to increased storm or weather hazards affecting our operations.

Table of Contents

Enhanced scrutiny on environmental matters and increasing public expectations on companies to address climate change may result in increased costs, changed demand for our soda ash, increased regulations and litigation and adverse impacts on our unit price and access to capital.

We are subject to strict laws and regulations regarding employee and process safety, and failure to comply with these laws and regulations could have a material adverse effect on our results of operations, financial condition and ability to distribute cash to unitholders.

We are subject to a number of federal and state laws and regulations related to safety, including the Occupational Safety and Health Administration, or OSHA, the Mine Safety and Health Administration, or MSHA, and comparable state statutes, the purposes of which are to protect the health and safety of workers. In addition, OSHA requires that we maintain information about hazardous materials used or produced in our operations and that we provide this information to employees, state and local governmental authorities, and local residents. Failure to comply with OSHA and MSHA requirements and related state regulations, including general industry standards and record keeping requirements, and to monitor and control occupational exposure to regulated substances, could have a material adverse effect on our results of operations, financial condition and ability to make cash distributions if we are subjected to significant penalties, fines or compliance costs, including any shutdown of one or more of our miners or the shutdown of our mine.

Failure to maintain effective quality control systems at our mining, processing and production facilities could have a material adverse effect on our business and operations.

The performance and quality of our products are critical to the success of our business. These factors depend significantly on the effectiveness of our quality control systems, which, in turn, depends on a number of factors, including the design of our quality control systems, our quality-training program and our ability to ensure that employees who operate our assets adhere to our quality control policies and guidelines. Any significant failure or deterioration of our quality control systems could have a material adverse effect on our business, financial condition and results of operations.

Our inability to acquire, maintain or renew financial assurances related to the reclamation and restoration of mining property could have a material adverse effect on our business, financial condition and results of operations.

Mining operations are generally obligated under federal, state and local laws to restore property in accordance with regulatory standards and an approved reclamation plan after it has been mined, and generally must also maintain financial assurances, such as surety bonds, to secure such obligations. To fulfill the financial assurances requirement, the WDEQ historically allowed us to “self-bond,” which commits us to pay directly for reclamation costs rather than obtaining a traditional surety bond. In May 2019, the State of Wyoming enacted legislation that limits our and other mine operators’ ability to self-bond and required us to seek other acceptable financial instruments to provide alternate assurances for our reclamation obligations by November 2020.

We provided such alternate assurances by timely securing a third-party surety bond effective October 15, 2020 (the “Surety Bond”) for the then-applicable full self-bond amount. After we secured the Surety Bond, the self-bond agreement was terminated. As of December 31, 2020, the amount of our Surety Bond was $36.2 million (for the 2018 operating year), which increased to $41.8 million (for the 2019 operating year) effective March 1, 2021 and the required Surety Bond amount was $41.8 million (for the 2020 operating year) effective January 7, 2022. As of the date of this Report, the impact on our net income and liquidity due to securing the Surety Bond is immaterial and we anticipate that to continue to be the case. The amount of such assurances that we are required to provide is subject to change upon periodic re-evaluation by the WDEQ’s Land Quality Division.

Our inability to secure financial assurances satisfactory to WDEQ could subject us to fines and penalties as well as the revocation of our operating permits. Such inability could result from a variety of factors, including:

•the State of Wyoming’s future decision to require mining operations to maintain surety bonds or other types of financial assurances;

•continued increases in the amount of required financial assurance;

•the lack of availability, high expense, or unreasonable terms of financial assurances;

•the ability of future financial assurance counterparties to require collateral; and

•the exercise by financial assurance counterparties of any rights to refuse to renew the financial assurance instruments.

Our inability to acquire, maintain, or renew necessary financial assurances related to the reclamation and restoration of mining property could have a material adverse effect on our business, financial condition, and results of operations.

Federal or state regulatory agencies have the authority to order certain of our mines to be temporarily or permanently closed under certain circumstances, which could materially and adversely affect our ability to meet our customers’ demands.

Federal or state regulatory agencies have the authority under certain circumstances following significant health and safety incidents, to order a mine to be temporarily or permanently closed. If this occurred, we may also be required to incur significant operating or capital expenditures to re-open the mine. In the event that these agencies order the closing of our Green River Basin facility, our soda ash sales contracts generally permit us to issue force majeure notices which suspend our obligations to deliver soda ash under these contracts. However, our customers may challenge our issuances of force majeure notices. If these challenges are successful, we may have to purchase soda ash from third-party sources, if it is available, to fulfill these obligations, incur capital expenditures to re-open the mine and/or negotiate settlements with the customers, which may include price reductions, the reduction of commitments, the extension of time for delivery or the termination of customers’ contracts. Any of these actions could have a material adverse effect on our business and results of operations.

Risks Related to Our Indebtedness and Liquidity

We may not have sufficient cash from operations following the establishment of cash reserves and payment of fees and expenses, including cost reimbursements to our general partner and its affiliates, to enable us to pay any quarterly distribution on our units.

We may not have sufficient available cash each quarter to pay the quarterly distribution at the current distribution level of $0.65 per unit, or $2.60 per unit on an annualized basis or at all. For example, in an effort to achieve greater financial and liquidity flexibility during the COVID-19 pandemic, our board of directors approved a suspension of quarterly distributions to our unitholders for each of the quarters ended June 30, 2020, September 30, 2020, December 31, 2020, March 31, 2021, and June 30, 2021. In order to pay the quarterly distribution at the current distribution level, we will require available cash of approximately $13 million per quarter, or $52 million per year, based on the number of common and general partner units currently outstanding.

The amount of cash we can distribute on our units principally depends upon the amount of cash we generate from our operations, which will fluctuate from quarter to quarter based on several factors, some of which are beyond our control, including, among other things:

•the market prices for soda ash in the markets in which we sell;

•the volume of natural and synthetic soda ash produced worldwide;

•domestic and international demand for soda ash in the flat glass, container glass, detergent, chemical and paper industries in which our customers operate or serve;

•the freight costs we pay to transport our soda ash to customers or various delivery points;

•the cost of electricity and natural gas used to power our operations;

•the amount of royalty payments we are required to pay to our lessors and licensor and the duration of our leases and license;

•political disruptions in the markets we or our customers serve, including any changes in trade barriers;

•our relationships with our customers and our sales agent’s ability to renew contracts on favorable terms to us;

•the creditworthiness of our customers;

•a cybersecurity event;

•the short and long-term impact of the COVID-19 pandemic (including existing or future variants), including the impact of government orders on our employees, suppliers, customers and operations;

•the impact of the CoC Transaction and our transition to the utilization of our own global distribution network;

•regulatory action affecting the supply of, or demand for, soda ash, our ability to mine trona ore, our transportation logistics, our operating costs and our operating flexibility;

•new or modified statutes, regulations, governmental policies and taxes or their interpretations; and

•prevailing U.S. and international economic conditions and foreign exchange rates.

In addition, the actual amount of cash we will have available for distribution will depend on other factors, some of which are beyond our control, including, among other things:

Table of Contents

•the level and timing of capital expenditures we make;

•the level of our operating, maintenance and general and administrative expenses, including reimbursements to our general partner for services provided to us;

•the cost of acquisitions, if any;

•our debt service requirements and other liabilities;

•fluctuations in our working capital needs;

•our ability to borrow funds and access capital markets;

•restrictions on distributions contained in debt agreements to which Sisecam Wyoming is a party;

•the amount of cash reserves established by our general partner; and

•other business risks affecting our cash levels.

Restrictions in the agreements governing Sisecam Wyoming’s indebtedness, including the Sisecam Wyoming Credit Facility and the Sisecam Wyoming Equipment Financing Arrangement, could limit its operations, and therefore ours, and adversely affect our business, financial condition, results of operations and ability to make quarterly cash distributions to our unitholders.

Sisecam Wyoming is party to a $225.0 million senior secured revolving credit facility (as amended, the “Sisecam Wyoming Credit Facility”), with each of the lenders listed on the respective signature pages thereof and Bank of America, N.A., as administrative agent, swing line lender and letter of credit issuer, and an equipment financing arrangement (the “Ciner Wyoming Equipment Financing Arrangement”) with Banc of America Leasing & Capital, LLC, as lender (the “Equipment Financing Lender”) including a Master Loan and Security Agreement, dated as of March 25, 2020 (as amended to date, the “Master Agreement”) and an Equipment Security Note Number 001, dated as of March 25, 2020 (the “Initial Secured Note”), and an Equipment Security Note Number 002, dated as of December 17, 2021 (the “Second Secured Note”), which provides the terms and conditions for the debt financing of certain equipment related to Sisecam Wyoming’s new natural gas-fired turbine co-generation facility that became operational in March 2020 and certain other equipment related to Ciner Wyoming’s operations.

The Sisecam Wyoming Credit Facility provides, among other things:

•a sublimit up to $40.0 million for the issuance of standby letters of credit and a sublimit up to $20.0 million for swingline loans;

•an accordion feature that enables Sisecam Wyoming to increase the revolving borrowings under the Sisecam Wyoming Credit Facility by up to an additional $250.0 million (subject to certain conditions);

•in addition to the aforementioned revolving borrowings, an ability to incur up to $225 million of additional term loan facility indebtedness to finance Sisecam Wyoming’s capacity expansion capital expenditures; (subject to certain conditions);

•a pledge by Sisecam Wyoming of substantially all of Sisecam Wyoming’s assets (subject to certain exceptions), including: (i) all present and future shares of any subsidiaries of Sisecam Wyoming (whether now existing or hereafter created) and (ii) all personal property of Sisecam Wyoming (subject to certain conditions);

•contains various covenants and restrictive provisions that limit (subject to certain exceptions) Sisecam Wyoming’s ability to: (i) incur certain liens or permit them to exist; (ii) incur or guarantee additional indebtedness; (iii) make certain investments and acquisitions related to Sisecam Wyoming’s operations in Wyoming; (iv) merge or consolidate with another company; (v) transfer, sell or otherwise dispose of assets, (vi) make distributions; (vii) change the nature of Sisecam Wyoming’s business; and (viii) enter into certain transactions with affiliates;

•a requirement to maintain a quarterly consolidated leverage ratio of not more than 3.25:1:00; provided, however, subject to certain conditions, Sisecam Wyoming shall have the ability to increase the maximum consolidated leverage ratio to 3.75:1.00 for a year while Sisecam Wyoming is undertaking capacity expansion capital expenditures;

•a requirement to maintain a quarterly consolidated interest coverage ratio of not less than 3.00:1.00; and

Table of Contents

•customary events of default including (i) failure to make payments required under the Sisecam Wyoming Credit Facility, (ii) events of default resulting from failure to comply with covenants and financial ratios, (iii) the occurrence of a voluntary change of control, as a result of which Sisecam Wyoming is directly or indirectly controlled by persons or entities not currently directly or indirectly controlling Sisecam Wyoming, (iv) the institution of insolvency or similar proceedings against Sisecam Wyoming, and (v) the occurrence of a cross default under any other material indebtedness Sisecam Wyoming may have. Upon the occurrence of an event of default, in their discretion, the Sisecam Wyoming Credit Facility lenders may exercise certain remedies, including, among others, accelerating the maturity of any outstanding loans, accrued and unpaid interest and all other amounts owing and payable such that all amounts thereunder will become immediately due and payable, and if not timely paid upon such acceleration, to charge Sisecam Wyoming a default rate of interest on all amounts outstanding under the Sisecam Wyoming Credit Facility.

For more information please read Part II, Item 8, “Financial Statements and Supplementary Data—Note 9—Debt—Sisecam Wyoming Credit Facility.”

With respect to the Sisecam Wyoming Equipment Financing Arrangement, in order to secure the payment and performance of Sisecam Wyoming’s obligations thereunder and other debt obligations owed by Sisecam Wyoming to the Equipment Financing Lender, Sisecam Wyoming granted to the Equipment Financing Lender a continuing security interest in all of Sisecam Wyoming’s right, title and interest in and to the Equipment (as defined in the Master Agreement) and certain related collateral. The Sisecam Wyoming Equipment Financing Arrangement (1) incorporates all covenants in the Sisecam Wyoming Credit Facility, now or hereinafter existing, or in any applicable replacement credit facility accepted in writing by the Equipment Financing Lender, that are based upon a specified level or ratio relating to assets, liabilities, indebtedness, rentals, net worth, cash flow, earnings, profitability, or any other accounting-based measurement or test, and (2) includes customary events of default subject to applicable grace periods, including, among others, (i) payment defaults, (ii) certain mergers or changes in control of Sisecam Wyoming, (iii) cross defaults with certain other indebtedness (a) to which the Equipment Financing Lender is a party or (b) to third parties in excess of $10 million, and (iv) the commencement of certain insolvency proceedings or related events identified in the Master Agreement. Upon the occurrence of an event of default, in its discretion, the Equipment Financing Lender may exercise certain remedies, including, among others, the ability to accelerate the maturity of any equipment note such that all amounts thereunder will become immediately due and payable, to take possession of the Equipment identified in any equipment note, and to charge Sisecam Wyoming a default rate of interest on all then outstanding or thereafter incurred obligations under the Sisecam Wyoming Equipment Financing Arrangement.

The provisions of the Sisecam Wyoming Credit Facility and the Sisecam Wyoming Equipment Financing Arrangement may affect Sisecam Wyoming’s ability to obtain future financing and pursue attractive business opportunities and flexibility in planning for, and reacting to, changes in business conditions. In addition, Sisecam Wyoming’s failure to comply with the provisions of the Sisecam Wyoming Credit Facility could result in an event of default, which could enable its lenders, subject to the terms and conditions thereof, to terminate all outstanding commitments and declare any outstanding principal of that debt, together with accrued and unpaid interest, to be immediately due and payable. If the payment of the Sisecam Wyoming Credit Facility’s debt is accelerated, the assets of Sisecam Wyoming may be insufficient to repay such debt in full. As a result, our results of operations and, therefore, our ability to distribute cash to unitholders, could be materially and adversely affected, and our unitholders could experience a partial or total loss of their investment. Please read Part II, Item 8, “Financial Statements and Supplementary Data—Note 9—Debt—Sisecam Wyoming Credit Facility” for more information.

Our level of indebtedness may increase, reducing our financial flexibility.

In the future, we may incur significant indebtedness in order to make future acquisitions or to develop or expand our facilities and mining capabilities. Our level of indebtedness could affect our operations in several ways, including:

•a significant portion of our cash flows could be used to service our indebtedness;

•a high level of debt would increase our vulnerability to general adverse economic and industry conditions;

•the covenants contained in the agreements governing our outstanding indebtedness will limit our ability to borrow additional funds, dispose of assets, pay distributions and make certain investments;

•a high level of debt may place us at a competitive disadvantage compared to our competitors that are less leveraged, and therefore may be able to take advantage of opportunities that our indebtedness would prevent us from pursuing;

•our debt covenants may also affect our flexibility in planning for, and reacting to, changes in the economy and our industry; and

Table of Contents

•a high level of debt may impair our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, distributions or for general corporate or other purposes.

A high level of indebtedness increases the risk that we may default on our debt obligations. Our ability to meet our debt obligations and to reduce our level of indebtedness depends on our future performance. General economic conditions and financial, business and other factors affect our operations and our future performance. Many of these factors are beyond our control. We may not be able to generate sufficient cash flows to pay the interest on our debt, and future working capital, borrowings or equity financing may not be available to pay or refinance such debt. Factors that will affect our ability to raise cash through an offering of our units or a refinancing of our debt include financial market conditions, the value of our assets and our performance at the time we need capital.

The amount of cash we have available for distribution to holders of our units depends primarily on our cash flow and not solely on profitability, which may prevent us from making cash distributions during periods when we record net income.

The amount of cash we have available for distribution depends primarily upon our cash flow, including cash flow from reserves and working capital or other borrowings, and not solely on profitability, which will be affected by non-cash items. As a result, we may pay cash distributions during periods when we record net losses for financial accounting purposes and may not pay cash distributions during periods when we record net income.

Risks Inherent in an Investment in Us

The CoC Transaction could significantly and adversely affect our results of operations because of difficulties related to integration, the achievement of synergies and other challenges.

•On December 21, 2021, Sisecam Chemicals USA Inc. (“Sisecam USA”) acquired from Ciner Enterprises Inc. (“Ciner Enterprises”) a 60% interest in Sisecam Chemicals Resources LLC (formerly known as Ciner Resources Corporation) (“Sisecam Chemicals”), an entity indirectly owning approximately 72% limited partner interest in the Partnership, as well as its 2% general partner interest and related incentive distribution rights, with Ciner Enterprises Inc. retaining a 40% interest in Sisecam Chemicals (the “CoC Transaction”). Prior to the completion of the CoC Transaction, Sisecam Chemicals was solely controlled and operated by Ciner Group, and there can be no assurances that Sisecam Chemicals, and its owners Sisecam USA and Ciner Enterprises (or their respective successors), will operate in a manner that allows for the achievement of substantial benefits to us. Further, it is possible that there could be a loss of our key customers, disruption of our ongoing businesses or unexpected issues, higher than expected costs and an integration process that takes longer than originally anticipated. Potential difficulties that may be encountered in the integration process include, among others:

•not retaining existing customer or logistics relationships or commercial arrangements, including in the Ciner Group’s global logistics network;

•difficulty obtaining new customer or logistics relationships and the terms of new commercial arrangements related thereto;

•not realizing anticipated operating synergies;

•integrating personnel from the two companies and the loss of key employees;

•potential unknown liabilities and unforeseen expenses or delays associated with and following the completion of the CoC Transaction;

•integrating relationships with customers, vendors and business partners; and

•the disruption of, or the loss of momentum in our ongoing business or inconsistencies in standards, controls, procedures and policies.

•In addition, at times the attention of certain members of our management and resources may be focused on integration of Sisecam Chemicals and diverted from our day-to-day business operations, which may disrupt our ongoing business.

Sisecam Chemicals, which is owned by Sisecam USA and Ciner Enterprises, indirectly owns and controls our general partner, which has sole responsibility for conducting our business and managing our operations. Our general partner and its affiliates and related parties, including Sisecam Chemicals, Sisecam USA and Ciner Enterprises, have conflicts of interest with us and

Table of Contents

our unitholders and limited duties to us and our unitholders, and they may favor their own interests to the detriment of us and our unitholders.

Sisecam Chemicals, which is owned 60% by Sisecam USA and 40% by Ciner Enterprises, indirectly owns and controls our general partner and the owners of Sisecam Chemicals have agreed that (i) Sisecam USA and Ciner Enterprises have a right to designate six directors and four directors, respectively, to the board of directors of Sisecam Chemicals, (ii) the board of directors of our general partner shall consist of six designees from Sisecam USA, two designees from Ciner Enterprises and three independent directors for as long as our general partner is legally required to appoint such independent directors and (iii) our right to appoint four managers to the board of managers of Ciner Wyoming shall be comprised of three designees from Sisecam USA and one designee from Ciner Enterprises. In turn, the directors of our general partner appoint all of our general partner’s officers. Although our general partner has a duty to manage us in a manner that is beneficial to us and our unitholders, the directors of our general partner who are appointed to represent Sisecam USA or Ciner Enterprises have a fiduciary duty to perform their duties in a manner beneficial to Sisecam USA or Ciner Enterprises, respectively. Therefore, conflicts of interest could arise between Sisecam Chemicals, Sisecam USA, Ciner Enterprises or any of their respective affiliates, including our general partner, on the one hand, and us or any of our unitholders, on the other hand. In resolving these conflicts of interest, our general partner may favor its own interests and the interests of Sisecam Chemicals, Sisecam USA and Ciner Enterprises over the interests of our common unitholders. These conflicts include, among others, the following situations:

•neither our partnership agreement nor any other agreement requires Sisecam Chemicals, Sisecam USA or Ciner Enterprises to pursue a business strategy that favors us, and the directors and officers of Sisecam USA and Ciner Enterprises have a fiduciary duty to make these decisions in the best interests of the stockholders of their respective companies, which may be contrary to our interests. Sisecam USA or Ciner Enterprises may choose to shift the focus of their respective investment and growth to areas not served by our assets;

•our general partner is allowed to take into account the interests of parties other than us, such as Sisecam Chemicals, Sisecam USA and Ciner Enterprises, in exercising certain rights under our partnership agreement, which may effectively limit its duty to our unitholders;

•all of the officers and eight of the directors of our general partner are also officers and/or directors of either Sisecam Chemicals, Sisecam USA and/or Ciner Enterprises or their respective affiliates and will owe fiduciary duties to their respective companies. These individuals may also devote some or a significant amount of their time to the businesses of Sisecam USA, Ciner Enterprises or their affiliates and will be compensated by such other parties accordingly;

•our partnership agreement replaces the fiduciary duties that would otherwise be owed by our general partner with contractual standards governing its duties, limits our general partner’s liabilities and restricts the remedies available to our unitholders for actions that, without such limitations, might constitute breaches of fiduciary duty;

•except in limited circumstances, our general partner has the power and authority to conduct our business without unitholder approval;

•dispute may arise under any commercial agreements between us and Şişecam LLC, Sisecam USA and/or Ciner Enterprises and their respective affiliates;

•Sisecam Chemicals, Sisecam USA and Ciner Enterprises and their respective other affiliates are not limited in their ability to compete with us and may directly or indirectly compete with us for acquisition opportunities and customers. For example, we face competition from Sisecam USA and its affiliates and Ciner Group’s trona-based soda ash production in Turkey and prospective soda ash production in the U.S. through a joint venture among affiliates of both Sisecam USA and Ciner Enterprises ;

•our general partner determines the amount and timing of asset purchases and sales, borrowings, issuances of additional partnership securities and the level of reserves, each of which can affect the amount of cash that we distribute to our unitholders;

•our general partner determines the amount and timing of any capital expenditure and whether a capital expenditure is classified as a maintenance capital expenditure, which reduces operating surplus, or an expansion or investment capital expenditure, which does not reduce operating surplus. Our partnership agreement does not set a limit on the amount of

Table of Contents

maintenance capital expenditures that our general partner may determine to be necessary or appropriate. Please read Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Capital Expenditures” for a discussion regarding when a capital expenditure constitutes a maintenance capital expenditure or an expansion capital expenditure. This determination can affect the amount of cash that is distributed to our unitholders;

•our general partner may cause us to borrow funds to pay cash distributions, even if the purpose or effect of the borrowing is to make incentive distributions;

•our partnership agreement permits us to classify up to $20.0 million as operating surplus, even if it is generated from asset sales, non-working capital borrowings or other sources that would otherwise constitute capital surplus. This cash may be used to fund distributions or to our general partner in respect of the incentive distribution rights;

•our general partner generally determines which costs incurred by it and its affiliates are reimbursable by us;

•our partnership agreement does not restrict our general partner from causing us to pay our general partner or its affiliates for any services rendered to us or from entering into additional contractual arrangements with its affiliates on our behalf;

•our general partner intends to limit its liability regarding our contractual and other obligations;

•our general partner may exercise its right to call and purchase our common units if it and its affiliates own more than 80% of the common units;

•our general partner controls the enforcement of obligations that it and its affiliates owe to us, including Sisecam Chemicals’ obligations under the Services Agreement and its commercial agreement with us;

•our general partner decides whether to retain separate counsel, accountants or others to perform services for us;

•our general partner may transfer its incentive distribution rights without unitholder approval; and

•our general partner may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to our general partner’s incentive distribution rights without the approval of the conflicts committee of the board of directors of our general partner or the unitholders. Any such election may result in lower distributions to the common unitholders in certain situations.

We currently do not have a majority of independent directors on the board of directors of our general partner, which could create conflicts of interests and pose a risk from a corporate governance perspective.

Pursuant to the Sisecam Chemicals Operating Agreement, the board of directors of our general partner shall consist of six designees from Sisecam USA, two designees from Ciner Enterprises and three independent directors for as long as our general partner is legally required to appoint such independent directors. As a publicly traded limited partnership, the NYSE rules do not require, and the board of directors of our general partner does not currently have, a majority of independent directors or a compensation committee or a nominating and corporate governance committee comprised of independent directors. In addition, while our partnership agreement permits our general partner to seek review by the conflicts committee comprised of independent directors of matters involving conflicts of interest between our general partner or any of its affiliates, on the one hand, and us, our partners and any of our subsidiaries, on the other hand, our general partner is not required or obligated to seek conflicts committee approval for any such matter. As a result, the lack of control of the independent directors on the board of directors of our general partner may create the potential for conflicts of interest and deprive us of the benefits of having entirely independent director approval of various decisions. Accordingly, unitholders do not have the same protections afforded to equity holders of entities that have a board of directors comprised of a majority of independent directors or are otherwise subject to all of the NYSE corporate governance requirements.

Operating performance and current and anticipated capital needs, including investments in expansion capital expenditures and acquisitions, may affect the amount distributed to unitholders.

We intend to pay a quarterly distribution to our unitholders to the extent we have sufficient cash from our operations after establishment of cash reserves, which may include current and anticipated expansion capital expenditures and acquisitions. In connection with the CoC Transaction, our management is evaluating whether and when to develop the potential Green River Expansion Project that we believe could increase production levels up to approximately 3.5 million tons of soda ash per year. We

Table of Contents

have conducted the initial basic design, secured certain related permits and are currently evaluating the detailed cost analysis pursuant to the basic design. If we decide to proceed with this project, it will require capital expenditures materially higher than have been recently incurred by Sisecam Wyoming. To maintain a disciplined financial policy and what we believe is a conservative capital structure, we may pay for the investment should we decide to proceed with it in part through cash generated by the business and in part through debt.

Our general partner has considerable discretion in determining the amount of available cash, the amount of distributions and the decision to make any distribution. Although our partnership agreement requires that we distribute all of our available cash quarterly, there is no guarantee that we will make quarterly cash distributions to our unitholders or at any other rate, and we have no legal obligation to do so.

For example, in an effort to achieve greater financial and liquidity flexibility during the COVID-19 pandemic, our board of directors approved a suspension of quarterly distributions to our unitholders for the quarter ended June 30, 2020, that continued for each of the quarters ended September 30, 2020, December 31, 2020, March 31, 2021, and June 30, 2021.

To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution level. There are no limitations in our partnership agreement on our ability to issue additional units, including units ranking senior to the common units. The incurrence of additional commercial borrowings or other debt to finance our growth strategy will increase our interest expense, which, in turn, may impact the cash that we have available to distribute to our unitholders.

Our partnership agreement does not contain a requirement for us to pay distributions to our unitholders, and we do not guarantee that we will pay the minimum quarterly distribution (as defined in our partnership agreement) or any distribution on the units in any quarter.

Our partnership agreement does not contain a requirement for us to pay distributions to our unitholders, and we do not guarantee that we will pay any distribution on the units in any quarter. For example, in an effort to achieve greater financial and liquidity flexibility during the COVID-19 pandemic, our board of directors approved a suspension of quarterly distributions to our unitholders for the quarter ended June 30, 2020, that continued for each of the quarters ended September 30, 2020, December 31, 2020, March 31, 2021, and June 30, 2021.

Our partnership agreement replaces our general partner’s fiduciary duties to holders of our common units with contractual standards governing its duties.

Our partnership agreement contains provisions that eliminate and replace the fiduciary standards to which our general partner would otherwise be held by Delaware law regarding fiduciary duty and replaces those duties with several different contractual standards. For example, our partnership agreement permits our general partner to make a number of decisions in its individual capacity, as opposed to in its capacity as our general partner, free of any duties to us and our unitholders other than the implied contractual covenant of good faith and fair dealing, which means that a court will enforce the reasonable expectations of the partners where the language in the partnership agreement does not provide for a clear course of action. This provision entitles our general partner to consider only the interests and factors that it desires and relieves it of any duty or obligation to give any consideration to any interest of, or factors affecting, us, our affiliates or our limited partners. Examples of decisions that our general partner may make in its individual capacity include:

•how to allocate business opportunities among us and its affiliates;

•whether to exercise its limited call right or assign it to one of its affiliates;

•whether to seek approval of the resolution of a conflict of interest by the conflicts committee of the board of directors of our general partner;

•how to exercise its voting rights with respect to the units it owns;

•whether to exercise its registration rights;

•whether to elect to reset target distribution levels;

•whether to transfer the incentive distribution rights or any units it owns to a third party; and

•whether or not to consent to any merger, consolidation or conversion of the partnership or amendment to the partnership agreement.

By purchasing a common unit, a unitholder is treated as having consented to the provisions in the partnership agreement, including the provisions discussed above.

Our partnership agreement restricts the remedies available to holders of our units for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty.

Our partnership agreement contains provisions that restrict the remedies available to unitholders for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty under Delaware law regarding fiduciary duty. For example, our partnership agreement provides that:

•whenever our general partner, the board of directors of our general partner or any committee thereof (including the conflicts committee) makes a determination or takes, or declines to take, any other action in their respective capacities, our general partner, the board of directors of our general partner and any committee thereof (including the conflicts committee), as applicable, is required to make such determination, or take or decline to take such other action, in good faith, meaning that it subjectively believed that the decision was in the best interests of our partnership, and, except as specifically provided by our partnership agreement, will not be subject to any other or different standard imposed by our partnership agreement, Delaware law, or any other law, rule or regulation, or at equity;

•our general partner will not have any liability to us or our unitholders for a decision made in its capacity as a general partner so long as such decisions are made in good faith;

•our general partner and its officers and directors will not be liable for monetary damages to us or our limited partners resulting from any act or omission unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that our general partner or its officers and directors, as the case may be, acted in bad faith or engaged in fraud or willful misconduct or, in the case of a criminal matter, acted with knowledge that the conduct was criminal; and

•our general partner will not be in breach of its obligations under the partnership agreement or its duties to us or our limited partners if a transaction with an affiliate or the resolution of a conflict of interest is:

◦approved by the conflicts committee of the board of directors of our general partner, although our general partner is not obligated to seek such approval;

◦approved by the vote of a majority of the outstanding common units, excluding any common units owned by our general partner and its affiliates;

◦determined by the board of directors of our general partner to be on terms no less favorable to us than those generally being provided to or available from unrelated third parties.

◦determined by the board of directors of our general partner to be fair and reasonable to us, taking into account the totality of the relationships among the parties involved, including other transactions that may be particularly favorable or advantageous to us.

In connection with a situation involving a transaction with an affiliate or a conflict of interest, any determination by our general partner or the conflicts committee must be made in good faith. If an affiliate transaction or the resolution of a conflict of interest is not approved by our common unitholders or the conflicts committee and the board of directors of our general partner determines that the resolution or course of action taken with respect to such affiliate transaction or conflict of interest satisfies either of the standards set forth in the third and fourth bullets above, then it will be presumed that, in making its decision, the board of directors acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the partnership challenging such determination, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption.

Our general partner and its indirect equityholders, including Sisecam USA and Ciner Enterprises, are not restricted in their ability to compete with us.

Our partnership agreement provides that our general partner will be restricted from engaging in any business activities other than acting as our general partner and those activities incidental to its ownership of interests in us. Affiliates of our general partner, and its other indirect equity owners, including Sisecam USA and Ciner Enterprises and their respective other subsidiaries and affiliates, are not prohibited from owning assets or engaging in businesses that compete directly or indirectly with us. Sisecam USA and Ciner Enterprises and their respective other subsidiaries and affiliates may make investments in and purchases of entities that acquire, own and operate other soda ash producing assets and that may compete with us.

As a result, under the circumstances described above, each of Sisecam Chemicals, Sisecam USA and/or Ciner Enterprises and their respective related parties have the ability to construct or acquire assets that directly compete with our assets.

general partner or any of its affiliates, including its executive officers and directors and Sisecam USA and/or Ciner Enterprises. Any such person or entity that becomes aware of a potential transaction, agreement, arrangement or other matter that may be an opportunity for us will not have any duty to communicate or offer such opportunity to us. Any such person or entity will not be liable to us or to any limited partner for breach of any fiduciary duty or other duty by reason of the fact that such person or entity pursues or acquires such opportunity for itself, directs such opportunity to another person or entity or does not communicate such opportunity or information to us. This may create actual and potential conflicts of interest between us and affiliates of our general partner and result in less than favorable treatment of us and our common unitholders.

Our general partner, or any transferee holding a majority of the incentive distribution rights, may elect to cause us to issue common units to it in connection with a resetting of the minimum quarterly distribution (as defined in our partnership agreement) and target distribution levels related to its incentive distribution rights, without the approval of the conflicts committee of our general partner or the holders of our common units. This election could result in lower distributions to holders of our common units in certain situations.

The holder or holders of a majority of the incentive distribution rights, which is initially our general partner, have the right, at any time when there are no subordinated units outstanding and it has received incentive distributions at the highest level to which it is entitled (48.0%) for each of the prior four consecutive fiscal quarters (and the amount of each such distribution did not exceed adjusted operating surplus for each such quarter), to reset the minimum quarterly distribution and the initial target distribution levels at higher levels based on our cash distribution at the time of the exercise of the reset election. Following such a reset election, the minimum quarterly distribution will be reset to an amount equal to the average cash distribution per unit for the two fiscal quarters immediately preceding the reset election (such amount is referred to as the “reset minimum quarterly distribution”), and the target distribution levels will be reset to correspondingly higher levels based on percentage increases above the reset minimum quarterly distribution. Our general partner has the right to transfer the incentive distribution rights at any time, in whole or in part, and any transferee holding a majority of the incentive distribution rights will have the same rights as our general partner with respect to resetting target distributions.

In the event of a reset of our minimum quarterly distribution and target distribution levels, our general partner will be entitled to receive, in the aggregate, a number of common units equal to that number of common units that would have entitled the holder of such units to an aggregate quarterly cash distribution in the two-quarter period prior to the reset election equal to the distribution to our general partner on the incentive distribution rights in the quarter prior to the reset election prior two quarters. Our general partner will also be issued the number of general partner units necessary to maintain its general partner interest in us that existed immediately prior to the reset election (approximately 2.0%). We anticipate that our general partner would exercise this reset right to facilitate acquisitions or internal growth projects that would not be sufficiently accretive to cash distributions per common unit without such conversion. However, our general partner or a transferee could also exercise this reset election at a time when it is experiencing, or expects to experience, declines in the cash distributions it receives related to its incentive distribution rights and may, therefore, desire to be issued common units rather than retain the right to receive incentive distributions based on target distribution levels that are less certain in the then-current business environment. This risk could increase if our incentive distribution rights have been transferred to a third-party. As a result, a reset election may cause our common unitholders to experience dilution in the amount of cash distributions that they otherwise would have received had we not issued new common units to our general partner in connection with resetting the target distribution levels.

Holders of our common units have limited voting rights and are not entitled to appoint our general partner or its directors, which could reduce the price at which our common units will trade.

Unlike the holders of common stock in a corporation, unitholders have only limited voting rights on matters affecting our business and, therefore, limited ability to influence management’s decisions regarding our business. Unitholders will have no right on an annual or ongoing basis to appoint our general partner or its board of directors. Pursuant to the Sisecam Chemicals Operating Agreement, the board of directors of our general partner shall consist of six designees from Sisecam USA, two designees from Ciner Enterprises and three independent directors for as long as our general partner is legally required to appoint such independent directors, and not by our unitholders. As a result of these limitations, the secondary market price at which the common units will trade could decline because of the absence or reduction of a takeover premium in the trading price. Unlike publicly traded corporations, we will not conduct annual meetings of our unitholders to appoint directors or to conduct other matters routinely conducted at annual meetings of stockholders of corporations. Our partnership agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting the unitholders’ ability to influence the manner or direction of management.

Even if holders of our common units are dissatisfied, they cannot initially remove our general partner without its consent.

If our unitholders are dissatisfied with the performance of our general partner, they will have limited ability to remove our general partner. The vote of the holders of at least 66-2/3% of all outstanding common units voting together as a single class is required to remove our general partner. As of March 10, 2022, SCW LLC owned 14,551,000 common units, which constitutes an aggregate of 73.5% of the common units in us.

Our general partner interest or the control of our general partner may be transferred to a third party without unitholder consent.

Our general partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all of its assets or otherwise without the consent of our unitholders. Furthermore, our partnership agreement does not restrict the ability of Sisecam Chemicals, Sisecam USA, Ciner Enterprises or, another entity that controls any such entity, to transfer or otherwise dispose of the corresponding indirect ownership interest in our general partner to a third party. In such a situation, the new owner of our general partner could be in a position to replace the board of directors and executive officers of our general partner with its own designees and thereby exert significant control over the decisions taken by the board of directors and executive officers of our general partner. This effectively permits a “change of control” without the vote or consent of our unitholders. For example, in connection with the CoC Transaction, Ciner Enterprises transferred a 60% interest in our U.S. sponsor to Sisecam USA, and Ciner Enterprises and Sisecam agreed that Sisecam shall have the right to designate six directors to our board of directors.

The incentive distribution rights held by our general partner, or indirectly held by Sisecam Chemicals, may be transferred to a third party without unitholder consent.

Our general partner or its equityholders may transfer the incentive distribution rights to a third party at any time without the consent of our unitholders. If Sisecam Chemicals transfers the incentive distribution rights to a third party but retains its ownership interest in our general partner, our general partner may not have the same incentive to grow our partnership and increase quarterly distributions to unitholders over time as it would if Sisecam Chemicals had retained ownership of the incentive distribution rights. For example, a transfer of incentive distribution rights by Sisecam Chemicals could reduce the likelihood of Sisecam Chemicals accepting offers made by us to purchase assets owned by it, as it would have less of an economic incentive to grow our business, which in turn would impact our ability to grow our asset base.

Our general partner has a limited call right that may require unitholders to sell their common units at an undesirable time or price.

If at any time our general partner and its affiliates own more than 80% of the common units, our general partner will have the right, which it may assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price equal to the greater of (1) the average of the daily closing price of the common units over the 20 trading days preceding the date three days before notice of exercise of the call right is first mailed and (2) the highest per-unit price paid by our general partner or any of its affiliates for common units during the 90-day period preceding the date such notice is first mailed. We refer to this right in this Report as the limited call right. As a result, unitholders may be required to sell their common units at an undesirable time or price and may receive no return or a negative return on their investment. Unitholders may also incur a tax liability upon a sale of their units. Our general partner is not obligated to obtain a fairness opinion regarding the value of the common units to be repurchased by it upon exercise of the limited call right. There is no restriction in our partnership agreement that prevents our general partner from issuing additional common units and exercising its limited call right. If our general partner exercised its limited call right, the effect would be to take us private and, if the units were subsequently deregistered, we would no longer be subject to the reporting requirements of the Exchange Act. As of March 10, 2022, SCW LLC owned an aggregate of 73.5% of our common units.

We may issue additional units, including units ranking senior to common units, without unitholder approval, which would dilute existing unitholder ownership interests.

Our partnership agreement does not limit the number of additional limited partner interests we may issue at any time without the approval of our unitholders. Any additional partnership interests that we issue may be senior to the common units in right of distribution, liquidation and voting. The issuance of additional common units or other equity interests of equal or senior rank will have the following effects:

•our existing unitholders’ proportionate ownership interest in us will decrease;

•the amount of cash available for distribution on each unit may decrease;

•because the amount payable to holders of incentive distribution rights is based on a percentage of the total cash available for distribution, the distributions to holders of incentive distribution rights will increase even if the per unit distribution on common units remains the same;

•the ratio of taxable income to distributions may increase;

•the relative voting strength of each previously outstanding unit may be diminished;

•the market price of the common units may decline;

Table of Contents

•the amounts available for distributions to our common unitholders may be reduced or eliminated; and

•the claims of the common unitholders to our assets in the event of our liquidations may be subordinated.

Our general partner intends to limit its liability regarding our obligations.

Our general partner intends to limit its liability under contractual arrangements so that the counterparties to such arrangements have recourse only against our assets, and not against our general partner or its assets. Our general partner may therefore cause us to incur indebtedness or other obligations that are nonrecourse to our general partner. Our partnership agreement permits our general partner to limit its liability, even if we could have obtained more favorable terms without the limitation on liability. In addition, we are obligated to reimburse or indemnify our general partner to the extent that it incurs obligations on our behalf. Any such reimbursement or indemnification payments would reduce the amount of cash otherwise available for distribution to our unitholders.

Our partnership agreement restricts the voting rights of unitholders owning 20% or more of our common units.

Our partnership agreement restricts unitholders’ voting rights by providing that any units held by a person or group that owns 20% or more of any class of units then outstanding, other than our general partner and its affiliates, their transferees and persons who acquired such units with the prior approval of the board of directors of our general partner, cannot vote on any matter.

Cost reimbursements due to our general partner and its affiliates for services provided to us or on our behalf will reduce our earnings and therefore our ability to distribute cash to our unitholders. The amount and timing of such reimbursements will be determined by our general partner.

Prior to making any distribution on the common units, we will reimburse our general partner and its affiliates for all expenses they incur and payments they make on our behalf. Our partnership agreement does not set a limit on the amount of expenses for which our general partner and its affiliates may be reimbursed. These expenses include salary, bonus, incentive compensation and other amounts paid to persons who perform services for us or on our behalf pursuant to the Services Agreement and expenses allocated to us by our general partner or its affiliates. Our partnership agreement provides that our general partner will determine in good faith the expenses that are allocable to us, including those allocated to us pursuant to the Services Agreement. The reimbursement of expenses and payment of fees, if any, to our general partner and its affiliates will reduce our earnings and therefore our ability to distribute cash to our unitholders.

Your liability may not be limited if a court finds that unitholder action constitutes control of our business.

A general partner of a partnership generally has unlimited liability for the obligations of the partnership, except for those contractual obligations of the partnership that are expressly made without recourse to the general partner. Our partnership is organized under Delaware law, and we conduct business primarily in Wyoming and Georgia. The limitations on the liability of holders of limited partner interests for the obligations of a limited partnership have not been clearly established in some jurisdictions. You could be liable for any and all of our obligations as if you were a general partner if a court or government agency were to determine that:

•we were conducting business in a state but had not complied with that particular state’s partnership statute; or

•your right to act with other unitholders to remove or replace the general partner, to approve some amendments to our partnership agreement or to take other actions under our partnership agreement constitute “control” of our business.

Unitholders may have liability to repay distributions and in certain circumstances may be personally liable for the obligations of the partnership.

Under certain circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under Section 17-607 of the Delaware Revised Uniform Limited Partnership Act, we may not make a distribution to our unitholders if the distribution would cause our liabilities to exceed the fair value of our assets. Delaware law provides that, for a period of three years from the date of the impermissible distribution, limited partners who received a distribution and who knew at the time of such distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. Transferees of common units are liable both for the obligations of the transferor to make contributions to the partnership that were known to the transferee at the time of transfer and for those obligations that were unknown if the liabilities could have been determined from the partnership agreement. Liabilities to partners on account of their partnership interests and liabilities that are non-recourse to the partnership are not counted for purposes of determining whether a distribution is permitted.

The New York Stock Exchange does not require a publicly-traded partnership like us to comply with certain of its corporate governance requirements.

Table of Contents

Our common units are listed on the NYSE under the symbol “SIRE.” Because we are a publicly-traded partnership, the NYSE does not require us to have a majority of independent directors on our general partner’s board of directors or to establish a compensation committee or a nominating and corporate governance committee. Accordingly, unitholders do not have the same protections afforded to certain corporations that are subject to all of the NYSE corporate governance requirements.

The market price of our common units could be adversely affected by sales of substantial amounts of our common units in the public markets, including sales by our existing unitholders.

Under our partnership agreement, we have agreed to register for resale under the Securities Act and applicable state securities laws any common units or other limited partner interests proposed to be sold by our general partner or any of its affiliates or their assignees if an exemption from the registration requirements of the Securities Act is not otherwise available. These registration rights continue for two years following any withdrawal or removal of our general partner. The sale or disposition of a substantial number of our common units in the public markets could have a material adverse effect on the price of our common units or could impair our ability to obtain capital through an offering of equity securities. We do not know whether any such sales would be made in the public market or in private placements, nor do we know what impact such potential or actual sales would have on our unit price in the future.

Our unitholders who fail to furnish certain information requested by our general partner or who our general partner, upon receipt of such information, determines are not eligible citizens are not entitled to receive distributions or allocations of income or loss on their common units and their common units will be subject to redemption.

Our general partner may require each limited partner to furnish information about his nationality, citizenship or related status. If a limited partner fails to furnish information about his nationality, citizenship or other related status within 30 days after a request for the information or our general partner determines after receipt of the information that the limited partner is not an eligible citizen, the limited partner may be treated as a non-citizen assignee. A non-citizen assignee does not have the right to direct the voting of his units and may not receive distributions in kind upon our liquidation. Furthermore, we have the right to redeem all of the common units of any holder that is not an eligible citizen or fails to furnish the requested information. The redemption price will be paid in cash or by delivery of a promissory note, as determined by our general partner.

Changes in accounting standards issued by the Financial Accounting Standards Board (“FASB”) could have a material effect on our balance sheet, revenue and results of operations, and could require a significant expenditure of time, attention and resources, especially by senior management.

Our accounting and financial reporting policies conform to Generally Accepted Accounting Principles in the U.S., which are periodically revised and/or expanded. The application of accounting principles is also subject to varying interpretations over time. Accordingly, we are required to adopt new or revised accounting standards or comply with revised interpretations that are issued from time to time by various parties, including accounting standard setters and those who interpret the standards, such as the Financial Accounting Standards Board and the Securities and Exchange Commission and our independent registered public accounting firm. Such new financial accounting standards may result in significant changes that could adversely affect our financial condition and results of operations.

Refer to Note 2 “Summary of Significant Accounting Policies - Recently Issued Accounting Pronouncements” of the Notes to the Consolidated Financial Statements for further discussion of these new accounting standards, including the implementation status and potential impact to our consolidated financial statements.

Tax Risks to Common Unitholders

Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, as well as our not being subject to a material amount of entity-level taxation by individual states. If the Internal Revenue Service (“IRS”) were to treat us as a corporation for U.S. federal income tax purposes or we were otherwise subject to a material amount of entity-level taxation, then our ability to distribute cash to our unitholders could be substantially reduced.

The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for U.S. federal income tax purposes. Despite the fact that we are organized as a limited partnership under Delaware law, we will be treated as a corporation for U.S. federal income tax purposes unless we satisfy a “qualifying income” requirement. Based upon our current operations, we believe we satisfy the qualifying income requirement. Failing to meet the qualifying income requirement or a change in current law could cause us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject us to taxation as an entity.

If we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal income tax on our taxable income at the corporate tax rate and we would also likely pay additional state and local income taxes at varying rates. Distributions to our unitholders would generally be taxed again as corporate distributions, which would be taxable as dividends for

Table of Contents

U.S. federal income tax purposes to the extent paid out of our current or accumulated earnings and profits as determined for U.S. federal income tax purposes, and no income, gains, losses, deductions or credits recognized by us would flow through to our unitholders. Because tax would be imposed upon us as a corporation, our cash available for distribution to our unitholders would be substantially reduced.

At the state level, several states have been evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise or other forms of taxation. Imposition of a material amount of any of these taxes in the jurisdictions in which we own assets or conduct business could substantially reduce the cash available for distribution to our unitholders.

If we were treated as a corporation for U.S. federal income tax purposes or otherwise subjected to a material amount of entity-level taxation, there would be a material reduction in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our common units.

Our partnership agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for U.S. federal, state or local income tax purposes, the target distribution amounts may be adjusted to reflect the impact of that law on us.

The tax treatment of publicly traded partnerships or an investment in our common units could be subject to potential legislative, judicial or administrative changes and differing interpretations, possibly on a retroactive basis.

The present U.S. federal income tax treatment of publicly traded partnerships, including us, or an investment in our common units may be modified by administrative, legislative or judicial changes or differing interpretations at any time. For example, from time to time, members of Congress have proposed and considered substantive changes to the existing U.S. federal income tax laws that would affect publicly traded partnerships, including elimination of partnership tax treatment for publicly traded partnerships.

The Treasury Department has issued, and in the future may issue, regulations interpreting those laws that affect publicly traded partnerships. We believe the income that we treat as qualifying satisfies the requirements under current regulations. However, there can be no assurance that there will not be further changes to U.S. federal income tax laws or the Treasury Department’s interpretation of the qualifying income rules in a manner that could impact our ability to qualify as a partnership for U.S. federal income tax purposes in the future.

We are unable to predict whether additional legislation or any other tax-related proposals will ultimately be enacted. Any modification to the U.S. federal income tax laws may be applied retroactively and could make it more difficult or impossible to meet the exception for certain publicly traded partnerships to be treated as partnerships for U.S. federal income tax purposes. Any such change could negatively impact the value of an investment in our common units.

Unitholders are required to pay taxes on their respective shares of our income even if they do not receive any cash distributions from us.

Each unitholder is treated as a partner to whom we will allocate taxable income even if the unitholder does not receive any cash distributions from us. Unitholders are required to pay U.S. federal income taxes and, in some cases, state and local income taxes, on their respective shares of our taxable income, whether or not they receive cash distributions from us. Our unitholders may not receive cash distributions from us equal to their respective shares of our taxable income or even equal to the actual tax due from them with respect to that income.

Tax gain or loss on the disposition of our common units could be more or less than expected.

If our unitholders sell their common units, they will recognize a gain or loss equal to the difference between the amount realized and their tax basis in those common units. Because distributions in excess of their allocable share of our net taxable income result in a decrease in their tax basis in their common units, the amount, if any, of such prior excess distributions with respect to the units they sell will, in effect, become taxable income to them if they sell such units at a price greater than their tax basis in those units, even if the price they receive is less than their original cost. Furthermore, a substantial portion of the amount realized, whether or not representing gain, may be taxed as ordinary income due to potential recapture of depreciation, depletion or certain other expense deductions and certain other items. In addition, because the amount realized includes a unitholder’s share of our liabilities, if they sell their units, they may incur a tax liability in excess of the amount of cash they receive from the sale.

Unitholders may be subject to limitations on their ability to deduct interest expense we incur.

Our ability to deduct business interest expense is limited for federal income tax purposes to an amount equal to the sum of our business interest income and a specified percentage of our “adjusted taxable income” during the taxable year computed without regard to any business interest income or expense, and in the case of taxable years beginning before 2022, any deduction allowable

Table of Contents

for depreciation, amortization, or depletion. Business interest expense that we are not entitled to fully deduct will be allocated to each unitholder as excess business interest and can be carried forward by the unitholder to successive taxable years and used to offset any excess taxable income allocated by us to the unitholder. Any excess business interest expense allocated to a unitholder will reduce the unitholder’s tax basis in its partnership interest in the year of the allocation even if the expense does not give rise to a deduction to the unitholder in that year.

Tax-exempt entities face unique tax issues from owning common units that may result in adverse tax consequences to them.

Investment in common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts, or “IRAs,” raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from U.S. federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable to them. Tax-exempt entities with multiple unrelated trades or businesses cannot aggregate losses from one unrelated trade or business to offset income from another to reduce total unrelated business taxable income. As a result, it may not be possible for tax-exempt entities to utilize losses from an investment in us to offset unrelated business taxable income from another unrelated trade or business and vice versa. Tax-exempt entities should consult a tax advisor before investing in our common units.

Non-U.S. unitholders will be subject to U.S. federal income taxes and withholding with respect to income and gain from owning our common units.

Non-U.S. persons are generally taxed and subject to U.S. federal income tax filing requirements on income effectively connected with a U.S. trade or business. Income allocated to our unitholders and any gain from the sale of our units will generally be considered to be “effectively connected” with a U.S. trade or business. As a result, distributions to a non-U.S. unitholder will be subject to withholding at the highest applicable effective tax rate and a non-U.S. unitholder who sells or otherwise disposes of a common unit will also be subject to federal income tax on the gain realized from the sale or disposition of that unit.

Moreover, the transferee of an interest in a partnership that is engaged in a United States trade or business is generally required to withhold 10% of the “amount realized” by the transferor unless the transferor certifies that it is not a non-U.S. person. While the determination of a partner’s “amount realized” generally includes any decrease of a partner’s share of the partnership’s liabilities, Treasury Regulations provide that the “amount realized” on a transfer of an interest in a publicly traded partnership, such as our common units, will generally be the amount of gross proceeds paid to the broker effecting the applicable transfer on behalf of the transferor, and thus will be determined without regard to any decrease in that partner’s share of a publicly traded partnership’s liabilities. The Treasury Regulations and recent guidance from the IRS further provide that withholding on a transfer of an interest in a publicly traded partnership will not be imposed on a transfer that occurs prior to January 1, 2023, and after that date, if effected through a broker, the obligation to withhold is imposed on the transferor’s broker. Non-U.S. persons should consult a tax advisor before investing in our common units.

If the IRS contests the U.S. federal income tax positions we take, the market for our common units may be adversely impacted and our cash flow available for distribution to our unitholders might be substantially reduced.

The IRS may adopt positions that differ from the conclusions of our counsel or from the positions we take, and the IRS’s position may ultimately be sustained. It may be necessary to resort to administrative or court proceedings to sustain some or all of our counsel’s conclusions or the positions we take and such positions may not ultimately be sustained. A court may not agree with some or all of our counsel’s conclusions or the positions we take. Any contest by the IRS may materially and adversely impact the market for our common units and the price at which they trade. In addition, our costs of any contest with the IRS will be borne indirectly by our unitholders and our general partner because the costs will reduce our distributable cash flow.

Pursuant to legislation applicable for partnership tax years beginning after 2017, if the IRS makes audit adjustments to our partnership tax returns, it may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustments directly from us. To the extent possible under these rules our general partner may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS in the year in which the audit is completed or, if we are eligible, issue a revised information statement to each current and former unitholder with respect to an audited and adjusted partnership tax return. Although our general partner may elect to have our current and former unitholders take such audit adjustment into account and pay any resulting taxes (including applicable penalties or interest) in accordance with their interests in us during the tax year under audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. If we make payments of taxes and any penalties and interest directly to the IRS in the year in which the audit is completed, our cash available for distribution to our unitholders might be substantially reduced, in which case our current unitholders may bear some or all of the tax liability resulting from such audit adjustment, even if the unitholders did not own units in us during the tax year under audit.

We treat each purchaser of our common units as having the same tax benefits without regard to the actual common units purchased. The IRS may challenge this treatment, which could adversely affect the value of the common units.

Because we cannot match transferors and transferees of common units, our depreciation, depletion and amortization positions may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could

Table of Contents

adversely affect the amount of tax benefits available to our unitholders. It also could affect the timing of these tax benefits or the amount of gain from the sale of common units and could have a negative impact on the value of our common units or result in audit adjustments to a unitholder’s tax returns.

We prorate our items of income, gain, loss and deduction between transferors and transferees of our units based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our common units based upon the ownership of our common units on the first day of each month, instead of on the basis of the date a particular common unit is transferred. Although Treasury Regulations allow publicly traded partnerships to use a similar monthly simplifying convention to allocate tax items among transferor and transferee unitholders, such tax items must be prorated on a daily basis and these regulations do not specifically authorize all aspects of our proration method. If the IRS were to successfully challenge our proration method, we may be required to change the allocation of items of income, gain, loss, and deduction among our unitholders.

A unitholder whose common units are the subject of a securities loan (e.g., a loan to a “short seller” to cover a short sale of common units) may be considered as having disposed of those common units. If so, the unitholder would no longer be treated for tax purposes as a partner with respect to those common units during the period of the loan and may recognize gain or loss from the disposition.

Because there is no tax concept of loaning a partnership interest, a unitholder whose common units are the subject of a securities loan may be considered as having disposed of the loaned units. In that case, the unitholder may no longer be treated for tax purposes as a partner with respect to those common units during the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those common units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those common units could be fully taxable as ordinary income. Our unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a loan to a short seller are urged to consult a tax advisor to discuss whether it is advisable to modify any applicable brokerage account agreements to prohibit their brokers from loaning their common units.

We have adopted certain valuation methodologies in determining a unitholder’s allocations of income, gain, loss and deduction. The IRS may challenge these methodologies or the resulting allocations, and such a challenge could adversely affect the value of our common units.

In determining the items of income, gain, loss and deduction allocable to our unitholders, we must routinely determine the fair market value of our assets. Although we may from time to time consult with professional appraisers regarding valuation matters, we make many fair market value estimates ourselves using a methodology based on the market value of our common units as a means to determine the fair market value of our assets. The IRS may challenge these valuation methods and the resulting allocations of income, gain, loss and deduction.

A successful IRS challenge to these methods or allocations could adversely affect the timing, character or amount of taxable income or loss being allocated to our unitholders. It also could affect the amount of gain from our unitholders’ sale of common units and could have a negative impact on the value of the common units or result in audit adjustments to our unitholders’ tax returns without the benefit of additional deductions.

As a result of investing in our common units, our unitholders may become subject to state and local taxes and return filing requirements in jurisdictions where we operate or own or acquire properties.

In addition to U.S. federal income taxes, our unitholders may be subject to other taxes, including state and local income taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we conduct business or control property now or in the future, even if they do not live in any of those jurisdictions. Further, unitholders may be subject to penalties for failure to comply with those requirements. As we make acquisitions or expand our business, we may own assets or conduct business in additional states or foreign jurisdictions that impose a personal income tax. It is a unitholder’s responsibility to file all applicable U.S. federal, foreign, state and local tax returns.

ITEM 2. Properties

In addition to the information provided below, information regarding our properties is included in Item 1. “Business — Our Operations,” “Leases and License” and “Summary of Trona Resources and Trona Reserves,” and “Internal Controls Disclosure over Trona Resources and Trona Reserves” and is incorporated by reference in this Item.

Our Green River Basin facility is situated on approximately 880 owned acres in the Green River Basin of Wyoming. We own the surface land and its improvements in fee, which we acquired pursuant to a quitclaim deed in 1991. See Item 1A, “Risk Factors—Risks Inherent in our Business and Industry—Defects in title or loss of any leasehold interests in our properties could limit our ability to conduct mining operations on these properties or result in significant unanticipated costs” for more information. We have operated our facility since 1996, prior to which Rhône-Poulenc was the operator. In addition, we have approximately 23,500 acres of subsurface leased/licensed mining areas. Four ponds on the property of our Green River Basin facility enable us to store the by-products from our refining process. We draw the water necessary for our refining processes from the nearby Green River. Our mining assets consist of two mining beds with five active mining faces at any one given time. The mine is served by four separate mine shafts.

Sisecam Chemicals leases 12,234 square feet of office space for its headquarters in Atlanta, Georgia which it utilizes to provide management and other shared services to the Partnership, pursuant to the various shared services agreements.

We believe that the size of our facilities is adequate for our current and anticipated needs.

Item 3. Legal Proceedings

From time to time we are party to various claims and legal proceedings related to our business. Although the outcome of these proceedings cannot be predicted with certainty, management does not currently expect any legal proceedings to have a material effect on our business, financial condition and results of operations. We cannot predict the nature of any future claims or proceedings, nor the ultimate size or outcome thereof and whether any damages resulting from them will be covered by insurance.

Item 4. Mine Safety Disclosures

Information regarding mine safety violations and other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95.1 to this Report.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our common units are listed on the NYSE under the symbol “SIRE.” As of March 10, 2022, SCW LLC owned 14,551,000 common units. The closing sales price of our common units on NYSE on March 10, 2022 was $19.95. SCW LLC has approximately 74% ownership interest in the common units and the public owned 5,236,748 common units which constitutes an approximately 26% ownership interest in us. There were 8 record holders of our outstanding common units as of March 10, 2022.

Distributions of Available Cash from Operating Surplus and Capital Surplus

General

Our partnership agreement requires that, within 60 days after the end of each quarter, we distribute our available cash to unitholders of record on the applicable record date.

Definition of Available Cash

Available cash generally means, for any quarter, all cash and cash equivalents on hand at the end of that quarter:

less, the amount of cash reserves established by our general partner to:

•provide for the proper conduct of our business (including reserves for our future capital expenditures and for anticipated future credit needs subsequent to that quarter);

•comply with applicable law, any of our debt instruments or other agreements; or

•provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters (provided that our general partner may not establish cash reserves for distributions if the effect of the establishment of such reserves will prevent us from distributing the minimum quarterly distribution on all common units);

plus, if our general partner so determines, all or any portion of the cash on hand on the date of determination of available cash for the quarter, resulting from working capital borrowings made subsequent to the end of such quarter.

The purpose and effect of the above is to allow our general partner, if it so decides, to use cash received by us after the end of the quarter but on or before the date of determination of available cash for the quarter, including cash on hand from working capital borrowings made after the end of the quarter but on or before the date of determination of available cash for that quarter, to pay distributions to unitholders. Under our partnership agreement, working capital borrowings are generally borrowings that are made under a credit facility, commercial paper facility or similar financing arrangement, and in all cases are used solely for working capital purposes or to pay distributions to partners, and with the intent of the borrower to repay such borrowings within 12 months with funds other than from additional working capital borrowings.

Any distributions we make will be characterized as made from “operating surplus” or “capital surplus.” Distributions of available cash from operating surplus are made differently than distributions of available cash that we would make from capital surplus. Operating surplus distributions will be made first to our unitholders. If our quarterly distributions exceed the first target distribution level described below, then operating surplus distributions will also be made to the holder of our incentive distribution rights. We do not anticipate that we will make any distributions from capital surplus. If we do make any capital surplus distribution, however, we will distribute such amount pro rata to all unitholders. The holder of the IDRs would generally not participate in any capital surplus distributions with respect to those rights.

In determining operating surplus and capital surplus, we will only take into account our proportionate share of our interest in our consolidated subsidiaries, so long as they are not wholly owned, as well as our proportionate share of entities accounted for under the equity method.

Operating Surplus

We define operating surplus as:

•$20.0 million; plus

•all of our cash receipts, including amounts received by us from OCI Enterprises under the Omnibus Agreement for periods prior to the consummation of Ciner Enterprises’ indirect acquisition of approximately 72% limited partner interests in us, as well as, our approximate 2.0% general partner interest and all of our incentive distribution rights (the “OCI Transaction”), and, by us from Sisecam Chemicals under the Services Agreement for periods subsequent to the consummation of the OCI Transaction, in each case, to the extent such amounts offset operating expenditures or lost revenue, and excluding cash from interim capital transactions (as defined below) and, under certain circumstances, the termination of hedge contracts; plus

Table of Contents

•working capital borrowings, if any, made after the end of a period but on or before the date of determination of operating surplus for the period; plus

•cash distributions paid in respect of equity issued (including incremental distributions on IDRs), to finance all or a portion of replacement, improvement or expansion capital expenditures in respect of the period from such financing until the earlier to occur of (1) the date the related capital improvement commences commercial service and (2) the date that it is abandoned or disposed of; plus

•cash distributions paid in respect of debt or equity issued (including incremental distributions on IDRs) to pay the construction period interest on debt incurred, or to pay construction period distributions on equity issued, to finance the expansion capital expenditures referred to above, in each case, in respect of the period from such financing until the earlier to occur of (1) the date the capital asset is placed in service and (2) the date that it is abandoned or disposed of; less

•all of our operating expenditures (as defined below); less

•the amount of cash reserves or our proportionate share of cash reserves in the case of subsidiaries that are not wholly-owned established by our general partner to provide funds for future operating expenditures; less

•all working capital borrowings not repaid within twelve months after having been incurred, or repaid within such twelve-month period with the proceeds of additional working capital borrowings; less

•any cash loss realized on disposition of an investment capital expenditure.

We will include in operating surplus, when collected, cash receipts equal to our proportionate share of accounts receivable that are retained by Sisecam Chemicals.

As described above, operating surplus does not reflect actual cash on hand that is available for distribution to our unitholders and is not limited to cash generated by our operations. For example, it includes a basket of $20.0 million that will enable us, if we choose, to distribute as operating surplus cash we receive in the future from non-operating sources such as asset sales, issuances of securities and long-term borrowings that would otherwise be distributed as capital surplus. In addition, by including, as described above, certain cash distributions on equity interests in operating surplus, we will increase operating surplus by the amount of any such cash distributions. As a result, we may also distribute as operating surplus up to the amount of any such cash that we receive from non-operating sources.

The proceeds of working capital borrowings increase operating surplus, and repayments of working capital borrowings are generally operating expenditures, as described below. Therefore, we will reduce operating surplus when we repay working capital borrowings. However, if we do not repay a working capital borrowing during the twelve-month period following such borrowing, it will be deemed to be repaid at the end of such period, thereby decreasing operating surplus at such time. When such working capital borrowing is, in fact, repaid, it will be excluded from operating expenditures because operating surplus will have been previously reduced by the deemed repayment.

We define operating expenditures in our partnership agreement, which generally means all of our cash expenditures, including:

•taxes,

•reimbursement of expenses to our general partner or its affiliates,

•payments made in the ordinary course of business under interest rate hedge agreements or commodity hedge agreements (provided that (1) with respect to amounts paid in connection with the initial purchase of an interest rate hedge contract or a commodity hedge contract, we will amortize such amounts over the life of the applicable interest rate hedge contract or commodity hedge contract, and (2) we will include in operating expenditures payments made in connection with the termination of any interest rate hedge contract or commodity hedge contract prior to the expiration of its stipulated settlement or termination date of such contracts in equal quarterly installments over the remaining scheduled life of such contract),

•compensation of officers and directors of our general partner,

•repayment of working capital borrowings,

•debt service payments, and

•payments made in the ordinary course of business under any hedge contracts.

However, operating expenditures will not include:

•repayment of working capital borrowings deducted from operating surplus pursuant to the penultimate bullet point of the definition of operating surplus above when such repayment actually occurs;

Table of Contents

•payments (including prepayments and prepayment penalties) of principal of and premium on indebtedness, other than working capital borrowings;

•expansion capital expenditures;

•investment capital expenditures;

•payment of transaction expenses relating to interim capital transactions;

•distributions to our partners (including distributions in respect of our IDRs); or

•repurchases of equity interests except to fund obligations under employee benefit plans.

Capital Surplus

Capital surplus is defined in our partnership agreement as any available cash distributed in excess of our operating surplus. Accordingly, we will generate capital surplus generally only by the following (which we refer to as “interim capital transactions”):

•borrowings, refinancings or refundings of indebtedness other than working capital borrowings and other than for items purchased on open account or for a deferred purchase price in the ordinary course of business;

•sales of our equity and debt securities;

•sales or other dispositions of assets, other than inventory, accounts receivable and other assets sold in the ordinary course of business or as part of normal retirement or replacement of assets; and

•capital contributions received.

Quarterly Distributions

In an effort to achieve greater financial and liquidity flexibility during the COVID-19 pandemic, on August 3, 2020, each of the members of the board of managers of Sisecam Wyoming approved a suspension of quarterly distributions to its members. In addition, effective August 3, 2020, in connection with the quarterly distribution for the quarter ended June 30, 2020, each of the members of the board of directors of our general partner approved a suspension of quarterly distributions to our unitholders that continued for each of the quarters ended September 30, 2020, December 31, 2020, March 31, 2021, and June 30, 2021.

In March 2021, the board of managers of Sisecam Wyoming approved a special $8.0 million distribution to, amongst other things, provide the Partnership with funds to retire the Ciner Resources Credit Facility.

In October 2021, the board of managers of Sisecam Wyoming approved a $15.0 million distribution to the members of Sisecam Wyoming.

On October 29, 2021, the Partnership declared its third quarter 2021 quarterly cash distribution of $0.340 per unit to both the limited partners and general partners. The quarterly cash distribution was paid on November 19, 2021 to unitholders of record on November 9, 2021.

On January 27, 2022, the Partnership declared its fourth quarter 2021 quarterly distribution. On February 18, 2022, we paid a quarterly cash distribution of $0.650 per limited partner unit to unitholders of record on February 7, 2022. The total distribution paid was $13.4 million with $12.9 million paid to our limited partners and $0.3 million and $0.3 million paid to our general partner for its general partner interests and incentive distribution rights, respectively.

Percentage Allocations of Distributions from Operating Surplus

The following table illustrates the percentage allocations of distributions from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under the column heading “Marginal Percentage Interest in Distributions” are the approximate percentage interests of our general partner and the unitholders in any distributions from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution per Unit Target Amount.” The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution also apply to quarterly distribution amounts that are less than the minimum quarterly distribution. Under our partnership agreement, our general partner has considerable discretion to determine the amount of available cash (as defined therein) for distribution each quarter to the Partnership’s unitholders, including the discretion to establish cash reserves that would limit the amount of available cash eligible for distribution to the Partnership’s unitholders for any quarter. The Partnership does not guarantee

Table of Contents

that it will pay the target amount of the minimum quarterly distribution listed below (or any distributions) on its units in any quarter. The percentage interests set forth below for our general partner (1) include its 2.0% general partner interest, (2) assume that our general partner has contributed any additional capital necessary to maintain its 2.0% general partner interest, (3) assume that our general partner has not transferred its IDRs and (4) assume that we do not issue additional classes of equity securities.


		Marginal Percentage Interest in Distributions
	Total Quarterly Distribution per Unit Target Amount	Unitholders		General Partner
Minimum Quarterly Distribution	$0.5000	98.0	%	2.0	%
First Target Distribution	above $0.5000 up to $0.5750	98.0	%	2.0	%
Second Target Distribution	above $0.5750 up to $0.6250	85.0	%	15.0	%
Third Target Distribution	above $0.6250 up to $0.7500	75.0	%	25.0	%
Thereafter	above $0.7500	50.0	%	50.0	%

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

References

Effective as of the end of day on December 31, 2020, Sisecam Chemicals exited ANSAC. As of January 1, 2021, Sisecam Chemicals began managing the Partnership’s sales and marketing efforts for exports with the ANSAC exit being complete. Sisecam Chemicals was able to establish business relationships with distributors by leveraging the Ciner Group’s distributor network and offering its customers an improved level of service and greater certainty of supply to the Partnership’s end customers. In connection with the settlement agreement with ANSAC, the Partnership met its 2021 sales commitments to ANSAC which were at substantially lower volumes than prior years. These 2021 sales to ANSAC were for export sales purposes, and required a fixed rate per ton selling, general and administrative expense. There remains a commitment to sell additional tons to ANSAC in 2022, which are at substantially lower volumes than 2021. Additionally, in connection with the settlement agreement, the Partnership met its obligation to purchase a limited amount of export logistics services in 2021. There is not an obligation to purchase logistic services from ANSAC beyond 2021. Through in part the Partnership’s affiliates, the Partnership has amongst other things: (i) obtained its own international customer sales arrangements, (ii) obtained third-party export port services, and (iii) chartered and executed its own international product delivery.

“Kaloglu Effective Date”), and (ii) to appoint Mr. Mehmet Nedim Kulaksizoglu as Chief Financial Officer of Sisecam Chemicals and its subsidiaries, including our general partner, effective upon the receipt of all requisite U.S. immigration and corporate approvals (the “Kulaksizoglu Effective Date”). Mr. Oguz Erkan has agreed to resign as the President and Chief Executive Officer of the general partner as of the Kaloglu Effective Date in order to pursue other opportunities with the Ciner Group. After the effectiveness of the foregoing resignation Mr. Erkan is expected to remain a member of the board of directors of our general partner and continue to serve as President and Chief Executive Officer of Ciner Enterprises. Mr. Ahmet Tohma has agreed to resign as the Chief Financial Officer of the general partner as of the Kulaksizoglu Effective Date in order to pursue other opportunities with the Ciner Group and is expected to continue to serve as the WE Soda Group’s Chief Financial Officer. As of the date of this filing, neither the Kaloglu Effective Date nor the Kulaksizoglu Effective Date has occurred.

COVID-19

COVID-19, including the Omicron variant, continues to cause certain disruptions to the economy throughout the world, including the United States and markets to which our products have historically been exported. There have been extraordinary actions taken by international, federal, state, and local public health and governmental authorities to contain and combat the outbreak and spread of COVID-19 in regions throughout the world, including travel bans, many vaccine mandate policies, quarantines, “stay-at-home” orders, and similar mandates for many individuals to restrict daily activities and for many businesses to curtail or cease normal operations. Vaccines for COVID-19 become widely available globally and individuals over five years old are eligible for the vaccine in the U.S.

Our Response to COVID-19

We continue to closely monitor the impact of the COVID-19 pandemic and all governmental actions in response thereto on all aspects of our business, including how it impacts our customers, employees, supply chain, distribution network, and cash flows. As COVID-19 vaccines become broadly available, we have encouraged employees to get vaccinated. We continue to use guidance from local health organizations, including the Centers for Disease Control and Prevention, to make decisions about our return to the workplace policies. Our focus has been the safety of our teams and this will continue to be our priority as we use data to address the COVID-19 pandemic. We continue to actively monitor and adhere to applicable local, state, federal, and international governmental guideline actions to better ensure the safety of our employees.

The impact of COVID-19

As the impact of COVID-19 evolved, we saw continued recovery in both domestic and international business in 2021. The soda ash volume sold in the first, second, third, and fourth quarters for 2021 increased 21.7%, decreased 9.7%, increased 7.8%, and increased 6.0%, respectively, compared to the immediately preceding quarter. The decline in the soda ash volume sold in the second quarter of 2021 compared to the first quarter of 2021 is primarily due to the first quarter of 2021 including significant international sales volumes associated with the initial impact of selling directly to international customers as part of our December 31, 2020 ANSAC exit. The production volumes in 2021 are at pre-COVID-19 pandemic levels, which we consider to be production levels prior to the second quarter 2020. The sales volumes in the second half of 2021 are at pre-COVID-19 pandemic levels. Sales volumes for the twelve months ended December 31, 2021 and 2020 were 2.8 million short tons and 2.2 million short tons, respectively.

For the year ended December 31, 2021 and 2020, we have incurred $1.8 million and $2.4 million, respectively, in costs directly related to COVID-19 primarily in the form of costs related to employee safety and retention and additional inventory storage and logistics costs.

Quarterly Distribution

In October 2021, the board of managers of Sisecam Wyoming approved a $15.0 million distribution to the members of Sisecam Wyoming.

Table of Contents

Green River Expansion Project

In connection with the CoC Transaction, we believe we have further opportunities to debottleneck our facility and are incorporating several of these in our holistic approach as we further explore whether to proceed with the Green River Expansion Project that, should we decide to proceed, we believe could increase production levels up to approximately 3.5 million short tons of soda ash per year or up to approximately 134% of the last five-year average of soda ash produced per year. We have conducted the initial basic design and secured certain related permits and are currently evaluating the detailed cost and market analysis pursuant to the basic design. If we proceed with this project, it will require capital expenditures materially higher than have been recently incurred by Sisecam Wyoming. The timing of the new Green River Expansion Project as well as any other expansion capital expenditures may also be impacted by the Partnership’s financial results including further negative volatility caused by the ongoing COVID-19 pandemic, including resurgences or subsequent variants of the virus.

Financial Assurance Regulatory Updates by the Wyoming Department of Environmental Quality (“WDEQ”)

Our operations are subject to oversight by the Land Quality Division of Wyoming Department of Environmental Quality (“WDEQ”). Our principal mine permit issued by the Land Quality Division, requires the Partnership to provide financial assurances for our reclamation obligations for the estimated future cost to reclaim the area of our processing facility, surface pond complex and on-site sanitary landfill. The Partnership provides such assurances through a third-party surety bond (the “Surety Bond”). According to the annual recalculation and submittal, the Surety Bond amount was $41.8 million and $36.2 million at December 31, 2021 and 2020, respectively. The amount of such assurances that we are required to provide is subject to change upon annual recalculation according to Department of Environmental Quality’s Guideline 12, annual site inspection and subsequent evaluation/approval by the WDEQ’s Land Quality Division.

For a discussion of risks in connection with future legislation relating to such financial assurances that could affect our business, financial condition and liquidity, see Part I, Item 1A, “Risk Factors - Risks Inherent in our Business and Industry - Our inability to acquire, maintain or renew financial assurances related to the reclamation and restoration of mining property could have a material adverse effect on our business, financial condition and results of operations.” for additional information.

Factors Affecting Our Results of Operations

Soda Ash Supply and Demand

Our net sales, earnings and cash flow from operations are primarily affected by the global supply of, and demand for, soda ash, which, in turn, directly impacts the prices that we and other producers charge for our products.

Historically, long-term demand for soda ash in the United States has been driven in large part by general economic growth and activity levels in the end-markets that the glass-making industry serves, such as the automotive and construction industries. Long-term soda ash demand in international markets has grown in conjunction with Gross Domestic Product. We expect that over the long-term, future global economic growth will positively influence global demand, which will likely result in increased exports, primarily from the United States, Turkey and to a limited extent, from China, the largest suppliers of soda ash to international markets. Currently, and in the near and mid-term we expect customers across all segments to continue managing and mitigating the impact of COVID-19 to their operations. Soda ash demand in the U.S. as well as the global market have recovered to pre-pandemic levels in 2021. There are select markets which continue to bear the impacts, however in most cases we see recovery taking place even where the demand was impacted to a great extent for a prolonged period.

Sales Mix

We will adjust our sales mix based upon what is the best margin opportunity for the business between domestic and international. Our operations have been and continue to be sensitive to fluctuations in freight and shipping costs and changes in international prices, which have historically been more volatile than domestic prices. Our gross profit will be impacted by the mix of domestic and international sales as a result of changes in logistics costs and our average selling prices.

International Commercial Restructuring and Expansion

As previously disclosed, Sisecam Chemicals, an affiliate of the Partnership, terminated its membership in ANSAC effective December 31, 2020. As of January 1, 2021, Sisecam Chemicals began managing the Partnership’s sales and marketing efforts for exports with the ANSAC exit being complete. In connection with the settlement agreement with ANSAC, Sisecam Chemicals continued to sell, at substantially lower volumes, product to ANSAC for export sales purposes, with a fixed rate per ton selling, general and administrative expense, and also fulfilled its obligation to purchase a limited amount of export logistics services in 2021. In connection with the settlement agreement with ANSAC, there remains sales commitments to ANSAC in 2022 where Sisecam Chemicals will continue to sell, at substantially lower volumes than 2021, product to ANSAC for export sales purposes, with a fixed rate per ton selling, general and administrative expense. Further, in 2022 there are no required export logistics services with ANSAC. The ANSAC exit allowed Sisecam Chemicals to improve access to customers and gain control over placement of its sales in the international marketplace in 2021. This enhanced view of the global market allows Sisecam Chemicals to better understand supply/demand fundamentals thus allowing better decision making for its business. Sisecam Chemicals continues to optimize its distribution network leveraging strengths of existing distribution partners while expanding as our business requires in certain target areas.

Although ANSAC has historically been our largest customer, the impact of Sisecam Chemicals' exit from ANSAC on our net sales, net income and liquidity was limited. With a low-cost position and improved access to international customers and control over placement of its sales in the international marketplace and logistics, we have adequately replaced these net sales made under the former agreement with ANSAC. Sisecam Chemicals leveraged the distributor network established by the Ciner Group in 2021 and continues to evaluate the distribution network and independent third-party distribution partners to optimize our reach into each market.

Energy Costs

One of the primary impacts to our profitability is our energy costs. Because we depend upon natural gas and electricity to power our trona ore mining and soda ash processing operations, our net sales, earnings and cash flow from operations are sensitive to changes in the prices we pay for these energy sources. Due to the historic volatility of natural gas prices, we expect to continue to hedge a portion of our forecasted natural gas purchases to mitigate volatility. During the first quarter of 2020, we completed construction of a natural gas-fired turbine co-generation facility that is capable of providing roughly one-third of our electricity and steam demands at our mine in the Green River Basin. This co-generation facility began operating in March 2020 and provided 172.6 million kWh of electricity which saved the Partnership $4.4 million in 2021 based on average purchased electricity costs and gas costs. In a normal production environment the facility is expected to provide us over 180.0 million kWh of electricity annually.

Table of Contents

How We Evaluate Our Business

Productivity of Operations

Our soda ash production volume is primarily dependent on the following three factors: (1) operating rate, (2) quality of our mined trona ore and (3) recovery rates. Operating rate is a measure of utilization of the effective production capacity of our facility and is determined in large part by productivity rates and mechanical on-stream times, which is the percentage of actual run times over the total time scheduled. We implement two planned outages of our mining and surface operations each year, typically in the second and third quarters. During these outages, which are scheduled to last approximately one week each, we repair and replace equipment and parts. Periodically, we may experience minor unplanned outages or unplanned extensions to planned outages caused by various factors, including equipment failures, power outages or service interruptions. The quality of our mine ore, which we refer to as our “ore grade,” is determined by measuring the trona ore recovered as a percentage of the deposit, which includes both trona ore and insolubles. Our ore grade for the years ended December 31, 2021 and 2020 was 86.3% and 85.7%, respectively. Plant recovery rates are generally determined by calculating the soda ash produced divided by the sum of the soda ash produced plus soda ash that is not recovered from the process. All of these factors determine the amount of trona ore we require to produce one short ton of soda ash and liquor, which we refer to as our “ore to ash ratio.” Our ore to ash ratio for the years ended December 31, 2021 and 2020 was 1.56: 1.0 and 1.60: 1.0, respectively.

Freight and Logistics

The soda ash industry is logistics intensive and involves careful management of freight and logistics costs. This freight costs make up a large portion of the total delivered cost to the customer. Delivery costs to most domestic customers and ANSAC primarily relate to rail freight services. Some domestic customers may elect to arrange their own freight and logistic services. Delivered costs to non-ANSAC international customers primarily consists of both rail freight services to the port of embarkation and the additional ocean freight to the port of disembarkation.

Sisecam Chemicals enters into contracts with one railroad company for the majority of the domestic rail freight services that the Partnership receives and the related freight and logistics costs are allocated to the Partnership. For the year ended December 31, 2021 and 2020, the Partnership shipped over 90% of our soda ash to our customers initially via a single rail line owned and controlled by the railroad company. The Partnership’s plant receives rail service exclusively from the railroad company and shipments by rail accounted for over 60% and over 80% of our total freight costs for the year ended December 31, 2021 and 2020, respectively. The decrease in the percentage of freight that is related to the railroad company is due primarily to the increased ocean freight in the year ended December 31, 2021 of direct international sales and their respective delivery locations.

If Sisecam Chemicals does not ship at least a significant portion of our soda ash production on the railroad company’s rail line during a twelve-month period, it must pay the railroad company a shortfall payment under the terms of our transportation agreement. The Partnership assists the majority of its domestic customers in arranging their freight services. During the year ended December 31, 2021 and 2020, Sisecam Chemicals had no shortfall payments and does not expect to make any such payments in the future. Sisecam Chemicals renewed its agreement with the railroad company in October 2021, which now expires on December 31, 2025.

Net Sales

Net sales include the amounts we earn on sales of soda ash. We recognize revenue from our sales when we satisfy the performance obligation defined in the contract with the customer. The performance obligation is typically met when goods are delivered to the carrier for shipment, which is the point at which the customer has the ability to direct the use of and obtain substantially all remaining benefits from the asset. The time at which delivery and transfer of title occurs is the point when the product leaves our facilities for domestic customers , the point when the product reaches the port of loading for ANSAC sales, and the point when the product is placed on a vessel for other international customers, thereby rendering our performance obligation fulfilled. Until the ANSAC exit on December 31, 2020, the time at which delivery and transfer of title occurred for ANSAC sales had been the same as domestic customers. Substantially all of our sales are derived from sales of soda ash, which we sell through our exclusive sales agent, Sisecam Chemicals. A small amount of our sales is derived from sales of production purge, which is a by-product liquor solution containing soda ash that is produced during the processing of trona ore. For the purposes of our discussion below, we include these transactions in domestic sales of soda ash and in the volume of domestic soda ash sold.

Until the end of 2020, sales prices for sales through ANSAC include the cost of freight to the ports of embarkation for overseas export or to Laredo, Texas for sales to Mexico. Sales prices for other international sales may include the cost of rail freight to the port of embarkation and the cost of ocean freight to the port of disembarkation for import by the customer.

Cost of products sold

Expenses relating to employee compensation, energy, including natural gas and electricity, royalties and maintenance materials constitute the greatest components of cost of products sold. These costs generally increase in line with increases in sales volume.

Table of Contents

Energy. A major item in our cost of products sold is energy, comprised primarily of natural gas and electricity. We primarily use natural gas to fuel our above-ground processing operations, including the heating of calciners, and we use electricity to power our underground mining operations, including our continuous mining machines, or continuous miners, and shuttle cars. The monthly Northwest Pipeline Rocky Mountain Index natural gas settlement prices, over the past five years, have ranged between $1.29 and $6.34. The average monthly Northwest Pipeline Rocky Mountain Index natural gas settlement prices for the years ended December 31, 2021 and 2020, were $3.90 and $2.07 per MMBtu, respectively. In early 2020, we constructed a new natural gas-fired turbine co-generation facility that is expected to provide roughly one-third of our electricity and steam demands at our mine in the Green River Basin. This co-generation facility began operating in March 2020 and provided 172.6 million kWh of electricity which saved the Partnership $4.4 million in 2021 based on average purchased electricity costs and gas costs. In a normal production environment the facility is expected to provide us over 180.0 million kWh of electricity annually. In order to mitigate the risk of gas price fluctuations, the Partnership expects to continue to hedge a portion of its forecasted natural gas purchases by entering into physical or financial gas hedges generally ranging between 20% and 80% of our expected monthly gas requirements, on a sliding scale, for approximately the next three years. See Item 7A, “Quantitative and Qualitative Disclosures about Market Risk - Commodity Price Risks,” for additional information.

Employee Compensation. See Item 8, Financial Statements and Supplementary Data—Note 11, “Employee Compensation,” for information on the various benefit plans offered and administered by Sisecam Chemicals.

Royalties. During the year ended December 31, 2021, we paid royalties to the State of Wyoming, the U.S. Bureau of Land Management and Sweetwater Royalties LLC. The royalties are calculated based upon a percentage of the value of soda ash and related products sold at a certain stage in the mining process. These royalty payments may be subject to a minimum domestic production volume from our Green River Basin facility. We are also obligated to pay annual rentals to our lessors and licensor regardless of actual sales. In addition, we pay a production tax to Sweetwater County, and trona severance tax to the State of Wyoming that is calculated based on a formula that utilizes the volume of trona ore mined and the value of the soda ash produced.

The royalty rates we pay to our lessors and licensor may change upon our renewal or renegotiation of such leases and license. On June 28, 2018, Sisecam Wyoming amended its License Agreement, dated July 18, 1961 (the “License Agreement”), with a predecessor in interest to Sweetwater Royalties LLC, to, among other things, (i) extend the term of the License Agreement to July 18, 2061 and for so long thereafter as Sisecam Wyoming continuously conducts operations to mine and remove sodium minerals from the licensed premises in commercial quantities; and (ii) set the production royalty rate for each sale of sodium mineral products produced from ore extracted from the licensed premises at eight percent (8%) of the net sales of such sodium mineral products. Any increase in the royalty rates we are required to pay to our lessors and licensor, or any failure by us to renew any of our leases and license, could have a material adverse impact on our results of operations, financial condition or liquidity, and, therefore, may affect our ability to distribute cash to unitholders. On December 11, 2020, the Secretary of the Interior authorized an industry-wide royalty reduction from currently set rates by establishing a 2% federal royalty rate for a period of ten years for all existing and future federal soda ash or sodium bicarbonate leases. This change by the Secretary of the Interior reduced the rates on our mineral leases with the U.S. Government from 6% to 2% as of January 1, 2021 and for the following ten years. This 4% rate reduction saved over $6.5 million in royalty fees based on our mining operations in 2021.

Selling, general and administrative expenses

Selling, general and administrative expenses incurred by our affiliates on our behalf are allocated to us based on the time the employees of those companies spend on our business and the actual direct costs they incur on our behalf. The Partnership has a Services Agreement (the “Services Agreement”), with our general partner and Sisecam Chemicals. Pursuant to the Services Agreement, Sisecam Chemicals has agreed to provide the Partnership with certain corporate, selling, marketing, and general and administrative services, in return for which the Partnership has agreed to pay Sisecam Chemicals an annual management fee, subject to quarterly adjustments, and reimburse Sisecam Chemicals for certain third-party costs incurred in connection with providing such services. In addition, under the agreement governing Sisecam Wyoming, Sisecam Wyoming reimburses us for employees who operate our assets and for support provided to Sisecam Wyoming.

Consolidated Results

Net sales. Net sales increased by 37.7% to $540.1 million for the year ended December 31, 2021 from $392.2 million for the year ended December 31, 2020, primarily driven by an increase in soda ash volumes sold of 26.6% and an increase in average sales price per short ton of 8.8% primarily due to continuing recovery of domestic and international demand from the significant negative impact from the COVID-19 pandemic. We operated at normal production capacity in the year ended December 31, 2021. Domestic average price was lower than the prior year same period due to customer mix, factoring in the overall volume growth as well as lower annual market prices which were set during the slow economy in late 2020 affected by the COVID-19 pandemic. Sales prices, particularly when considering the impact of rising logistics costs, in the year ended December 31, 2021 had not fully recovered to pre-COVID-19 pandemic levels. Increase in net sales and cost of product sold from 2020 to 2021 is also impacted by an increase in non-ANSAC international sales which include ocean freight in both net sales and cost of product sold.

Cost of products sold. Cost of products sold, including depreciation, depletion and amortization expense and freight costs, increased by 36.1% to $460.1 million for the year ended December 31, 2021 from $338.1 million for the year ended December 31, 2020, primarily due to significant increases in overall soda ash sales volumes. The increase in cost of products sold is also due to supplier cost inflation as well as significant increases in ocean freight rates primarily from the high demand in the global supply chain as well as price increases in natural gas. In addition, the increases from 2020 to 2021 are also attributable to an increase in non-ANSAC international sales which include ocean freight in both net sales and cost of product sold.

Selling, general and administrative expenses. Our selling, general and administrative expenses increased 8.3% to $23.5 million for the year ended December 31, 2021, compared to $21.7 million for the year ended December 31, 2020. The increase was primarily due to developing our internal international sales, marketing, and logistics infrastructure while additionally incurring an incremental fixed rate cost per ton on sales to ANSAC in 2021.

Operating income. Operating income increased by 74.4% to $56.5 million for the year ended December 31, 2021, compared to $32.4 million for the year ended December 31, 2020. The increase is primarily due to the sales volume improvement to the pre-COVID pandemic level, the international sales price improvement to the pre-COVID pandemic level, and the domestic sales price slow recovery toward the pre-COVID pandemic level. Despite the sales recovery from the negative impact of the COVID-19

Table of Contents

pandemic, the operating income has not yet recovered to the pre-pandemic level as supply chain costs have increased at a much faster pace than sales.

Net income. As a result of the foregoing, net income increased by 91.1% to $51.4 million for the year ended December 31, 2021, compared to $26.9 million for the year ended December 31, 2020

Liquidity and Capital Resources

Sources of liquidity include cash generated from operations and borrowings under credit facilities and capital calls from partners. We use cash and require liquidity primarily to finance and maintain our operations, fund capital expenditures for our property, plant and equipment, make cash distributions to holders of our partnership interests, pay the expenses of our general partner and satisfy obligations arising from our indebtedness. Our ability to meet these liquidity requirements will depend on our ability to generate cash flow from operations.

Our sources of liquidity include:

•cash generated from our operations;

•Approximately $155.0 million ($225.0 million, less $70.0 million outstanding) was available for borrowing and undrawn under the Sisecam Wyoming Credit Facility as of December 31, 2021, subject to availability; during the year ended December 31, 2021, we had borrowings of $83.5 million under the Sisecam Wyoming Credit Facility, offset by repayments of $116.0 million; The Prior Sisecam Wyoming Credit Facility was terminated and replaced by the Sisecam Wyoming Credit Facility on October 28, 2021, with approximately $105.0 million drawn on the Sisecam Wyoming Credit Facility that was used to terminate the Prior Sisecam Wyoming Credit Facility. Please read Part II, Item 8, Financial Statements - Note 9, “Debt,” for details.

We continue to analyze all aspects of our spending in order to maintain liquidity at levels we believe are necessary in order to satisfy cash requirements over the next twelve months and beyond. We are closely reviewing maintenance capital expenditures at our Wyoming facility to adequately maintain the physical assets. In addition, we are subject to business and operational risks that could adversely affect our cash flow, access to borrowings under the Sisecam Wyoming Credit Facility, and ability to make monthly installment payments under the Sisecam Wyoming Equipment Financing Arrangement. Our ability to satisfy debt service obligations, to fund planned capital expenditures, to make acquisitions and to make distributions will depend upon our future operating performance, which, in turn, will be affected by prevailing economic conditions, our business and other factors, some of which are beyond our control.

We expect our ongoing working capital and capital expenditures to be funded by cash generated from operations and borrowings under the Sisecam Wyoming Credit Facility. The amount, timing and classification of any such capital expenditures could affect the amount of cash that is available to be distributed to our unitholders.

In addition, we are subject to business and operational risks that could adversely affect our cash flow and access to borrowings under the Sisecam Wyoming Credit Facility and the Sisecam Wyoming Equipment Financing Arrangement.

We intend to pay a quarterly distribution to unitholders of record, to the extent we have sufficient cash from our operations after establishment of cash reserves, funding of any acquisitions and expansion capital expenditures, paying debt obligations and payment of fees and expenses, including payments to our general partner and its affiliates.

Working Capital Requirements

Working capital is the amount by which current assets exceed current liabilities. Our working capital requirements have been, and will continue to be, primarily driven by changes in accounts receivable and accounts payable, which generally fluctuate with changes in volumes, contract terms and market prices of soda ash in the normal course of our business. Other factors impacting changes in accounts receivable and accounts payable could include the timing of collections from customers and payments to suppliers, and supplier cost inflation, as well as the level of spending for maintenance and growth capital expenditures. A material adverse change in operations or available financing under the Sisecam Wyoming Credit Facility could impact our ability to fund our requirements for liquidity and capital resources. Historically, we have not made working capital borrowings to finance our operations. As of December 31, 2021, we had a working capital balance of $134.2 million as compared to a working capital balance of $109.3 million as of December 31, 2020. The primary driver for the increase in our working capital balance was an increase in accounts receivable related to increases in sales in the fourth quarter ended December 31, 2021 in comparison to sales in the fourth quarter ended December 31, 2020.

Capital Expenditures

Our operations require investments to expand, upgrade or enhance existing operations and to meet evolving environmental and safety regulations. We distinguish between maintenance and expansion capital expenditures. Maintenance capital expenditures

Table of Contents

(including expenditures for the replacement, improvement or expansion of existing capital assets) are made to maintain, over the long-term, our operating income or operating capacity. Examples of maintenance capital expenditures are expenditures to upgrade and replace mining equipment and to address equipment integrity, safety and environmental laws and regulations. Our maintenance capital expenditures do not include actual or estimated capital expenditures for replacement of our trona reserves. Expansion capital expenditures are incurred for acquisitions or capital improvements made to increase, over the long-term, our operating income or operating capacity. Examples of expansion capital expenditures include the acquisition and/or construction of complementary assets to grow our business and to expand existing facilities, such as projects that increase production from existing facilities or reduce costs, to the extent such capital expenditures are expected to increase our long-term operating capacity or operating income.

The following table summarizes our capital expenditures, on an accrual basis:


	Years Ended December 31,
($ in millions)	2021		2020
Maintenance	27.0		$	22.9
Expansion	0.8		14.5
Total	$	27.8	$	37.4

During the year ended December 31, 2021, capital spending decreased $9.6 million as compared to the year ended December 31, 2020. The decrease was primarily due to the COVID-19 pandemic during which we tried to maintain sound financial liquidity by postponing capital expenditures for expansion. The decrease was also attributable to the completion of our new co-generation facility, which became operational in March 2020.

Cash Flows Discussion

The following is a summary of cash provided by or used in each of the indicated types of activities:


	Years Ended December 31,				Percent Increase/(Decrease)
($ in millions)	2021		2020			2021 vs 2020
Cash provided by (used in):
Operating activities	$	54.2	$	54.7		(0.9)	%
Investing activities	$	(24.9)	$	(42.2)		(41.0)	%
Financing activities	$	(27.1)	$	(26.9)		0.7	%

Operating Activities

Cash provided by operating activities decreased to $54.2 million during the year ended December 31, 2021 compared to $54.7 million of cash provided during the year ended December 31, 2020, primarily as a result of the following:

•an increase of 91.1% of net income of $51.4 million during the year ended December 31, 2021, compared to $26.9 million during the year ended December 31, 2020, and

•an increase of $28.0 million in working capital used by operating activities from $2.4 million during the year ended December 31, 2020 to $30.4 million year ended December 31, 2021. The increase was primarily due to higher accounts receivable balance at December 31, 2021 as a result of higher net sales for the three months ended December 31, 2021 compared to the same period ended December 31, 2020. It is partly offset by the higher balances of accounts payable and accrued expenses as of December 31, 2021.

Investing Activities

We used cash flows of $24.9 million in investing activities during the year ended December 31, 2021, compared to $42.2 million used the year ended December 31, 2020, primarily related to capital projects as described in “Capital Expenditures” above.

Financing Activities

Cash used in financing activities was $27.1 million during the year ended December 31, 2021, compared to $26.9 million used for the year ended December 31, 2020. Higher repayments than borrowings on debt offset by lower distributions for the year ended December 31, 2021 compared to 2020 resulted in slightly more cash used in financing activities during the year ended December 31, 2021

Borrowings under the Prior Sisecam Wyoming Credit Facility were at variable interest rates.

Debt

See Part II, Item 8, Financial Statements and Supplementary Data - Note 9, “Debt,” for details of our outstanding debt.

Material Cash Requirements

The following table sets forth a summary of our material cash requirements related to our significant contractual obligations as of December 31, 2021:


	Payments Due by Period

Total	$	68.3	$	16.1	$	17.5	$	11.6	$	81.6	$	180.4	$	375.5

(1) Purchase obligations primarily include agreement to purchase goods or services that are enforceable and legally binding and that specify all significant terms. We have certain long-term utility contracts with various terms extending through 2024 with year-to-year renewal options thereafter. These commitments are designed to mitigate price volatility and assure source of supply for our normal requirements. The amounts include financial natural gas hedge commitments, as well as, purchase obligations under a contract for the transportation of gas and the contract for the transportation of gas may be cancelled by either party upon twelve months’ advance written notice to the other party. Purchase obligations also include ocean freight contracts primarily for vessels with terms through December 31, 2022.

(2) Long-term debt interest payments set forth in the table above are based on our contractual rates, or in the case of variable interest rate obligations, the weighted average interest rates as of December 31, 2021.

(3) Minimum contractual rental commitments of various operating leases, including renewal periods. Not included in the table above are the operating lease contracts that Sisecam Chemicals typically enters into with various lessors for railcars to transport product to customer locations and warehouses. Rail car leases under these contractual commitments range for periods from one to ten years. Sisecam Chemicals’ obligation related to these rail car leases are $8.4 million in 2022, $5.0 million in 2023, $3.4 million in 2024, $2.2 million in 2025, $1.6 million in 2026 and $0.5 million thereafter.

(4) Asset retirement obligations are the liability for the present value of cost we estimate we will incur to retire certain assets. The amount reported in the Contractual Obligations table above, represents the undiscounted estimated cost to retire such assets. The estimated average timing of these obligations is in excess of thirty years. Based on the information about the reclamation liability recently obtained from WDEQ, the current estimated reclamation cost of $41.8 million is used to calculate the asset retirement obligation estimate. See Part II, Item 8, Financial Statements and Supplementary Data - Note 14, Commitments and Contingencies - “Mine Permit Bonding Commitment,” for more information regarding our off-balance-sheet arrangements.

Impact of Inflation

The impact of inflation has become significant in recent months and in the U.S. economy and may increase our cost to acquire or replace properties, plant and equipment. Inflation may also increase our costs of labor and supplies. To the extent permitted by competition, regulation and existing agreements, we pass along increased costs to our customers in the form of higher selling prices, and we expect to continue this practice.

Table of Contents

Non-GAAP Financial Measures

We report our financial results in accordance with generally accepted accounting principles in the United States (“GAAP”). We also present the non-GAAP financial measures of:

•Adjusted EBITDA;

•Distributable cash flow; and

•Distribution coverage ratio.

We define Adjusted EBITDA as net income (loss) plus net interest expense, income tax, depreciation, depletion and amortization, equity-based compensation expense and certain other expenses that are non-cash charges or that we consider not to be indicative of ongoing operations. Distributable cash flow is defined as Adjusted EBITDA less net cash paid for interest, maintenance capital expenditures and income taxes, each as attributable to Sisecam Resources LP. The Partnership may fund expansion-related capital expenditures with borrowings under existing credit facilities such that expansion-related capital expenditures will have no impact on cash on hand or the calculation of cash available for distribution. In certain instances, the timing of the Partnership’s borrowings and/or its cash management practices will result in a mismatch between the period of the borrowing and the period of the capital expenditure. In those instances, the Partnership adjusts designated reserves (as provided in the partnership agreement) to take account of the timing difference. Accordingly, expansion-related capital expenditures have been excluded from the presentation of cash available for distribution. Distributable cash flow will not reflect changes in working capital balances. We define distribution coverage ratio as the ratio of distributable cash flow as of the end of the period to cash distributions payable with respect to such period.

Adjusted EBITDA is a non-GAAP supplemental financial measure that management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess the Partnership’s operating performance and liquidity. Adjusted EBITDA may provide an operating performance comparison to other publicly traded partnerships in our industry, without regard to historical cost basis or financing methods. Adjusted EBITDA may also be used to assess the Partnership’s liquidity including such things as the ability of our assets to generate sufficient cash flows to make distributions to our unitholders and our ability to incur and service debt and fund capital expenditures.

Distributable cash flow and distribution coverage ratio are non-GAAP supplemental financial measures that management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess the Partnership’s liquidity, including:

•the ability of our assets to generate sufficient cash flow to make distributions to our unitholders and

•our ability to incur and service debt and fund capital expenditures.

We believe that the presentation of Adjusted EBITDA provides useful information to our investors in assessing our financial conditions, results of operations and liquidity. Distributable cash flow and distribution coverage ratio provide useful information to investors in assessing our liquidity. The GAAP measures most directly comparable to Adjusted EBITDA is net income and net cash provided by operating activities. The GAAP measure most directly comparable to distributable cash flow and distribution coverage ratio is net cash provided by operating activities. Our non-GAAP financial measures of Adjusted EBITDA, distributable cash flow and distribution coverage ratio should not be considered as alternatives to GAAP net income, operating income, net cash provided by operating activities, or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EBITDA and distributable cash flow have important limitations as analytical tools because they exclude some, but not all items that affect net income and net cash provided by operating activities. Investors should not consider Adjusted EBITDA, distributable cash flow and distribution coverage ratio in isolation or as a substitute for analysis of our results as reported under GAAP. Because Adjusted EBITDA, distributable cash flow and distribution coverage ratio may be defined differently by other companies, including those in our industry, our definition of Adjusted EBITDA, distributable cash flow and distribution coverage ratio may not be comparable to similarly titled measures of other companies, thereby diminishing its utility.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions regarding matters that are inherently uncertain and that ultimately affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. The estimates and assumptions are based on management’s experience and understanding of current facts and circumstances. These estimates may differ from actual results.

We believe our judgments and related estimates associated with transactions with our affiliates and revenue recognition are critical in the preparation of our consolidated financial statements. Management has discussed the development and selection of these critical accounting judgments and estimates with the Audit Committee of our Board of Directors, and the Audit Committee has reviewed our disclosures relating to them, which are presented below.

Transactions with Affiliates

Agreements and transactions with affiliates have a significant impact on the Partnership’s financial statements because the Partnership is a subsidiary and investee within two different global group structures. Agreements directly between the Partnership and other affiliates, or indirectly between affiliates that the Partnership does not control, can have a significant impact on recorded amounts or disclosures in the Partnership's financial statements, including any commitments and contingencies between the Partnership and affiliates, or potentially, third parties.

For instance Sisecam Chemicals, an upstream affiliate of the Partnership, acts as a shared service center for a variety of functions, including logistics and retirement benefits for Ciner Enterprises and its investee affiliates. Sisecam Chemicals is the exclusive sales agent for the Partnership and allocates costs to the Partnership for ocean freight cost, selling, general and administrative expenses, retirement and postretirement benefits, and railcar leases. For more information related to these expenses see Item 8, “Financial Statements and Supplementary Data” Note 15, “Agreements and Transactions with Affiliates.”

There may be certain items that affiliates are in the process of evaluating how the Partnership may benefit or participate in the development, including participating in the related expenditures. In addition, the general partner may contract and/or develop certain transactions or assets on its own or through affiliates. Further upstream affiliates of the Partnership, including affiliates of Şişecam Parent may enter into agreements that limit or otherwise adversely impact the Partnership.

There is judgment in the Partnership’s identification, evaluation, and disclosure of affiliate relationships, transactions, and commitments and contingencies.

Revenue Recognition

The majority of the Partnership’s revenues generated are recognized upon delivery and transfer of title to the product to our customers. Generally the time at which delivery and transfer of title occurs, for the majority of our contracts with customers, is the point when the Partnership ships product to customers, thereby rendering our performance obligation fulfilled. Additionally, the Partnership has made an accounting policy election to account for shipping and handling activities as fulfillment costs. For more information related to revenue see Item 8, “Financial Statements and Supplementary Data” - Note 2 - “Summary of Significant Accounting Policies.”

ITEM 7A. Quantitative and Qualitative Disclosures about Market Risk

Our exposure to the financial markets consists of changes in interest rates relative to the balance of our outstanding debt obligations and derivatives that we have employed from time to time to manage our exposure to changes in market interest rates, foreign currency rate and commodity prices. We do not use financial instruments or derivatives for trading or other speculative purposes.

Interest Rate Risks

The aggregate principal amount of variable rate debt we had outstanding under our debt instruments as of December 31, 2021 was $70.0 million (as of December 31, 2020: $103.5 million). We have interest rate swap contracts, designated as cash flow hedges, to mitigate our exposure to possible increases in interest rates. The swap contracts consist of three individual $12.5 million swaps with an aggregate notional value of $37.5 million at December 31, 2021 and three individual $12.5 million swaps with an aggregate notional value of $37.5 million at December 31, 2020. The swaps have various maturities through 2024. The fair value liability of these interest rate swaps was $0.4 million as of December 31, 2021. The Partnership’s variable rate debt had a weighted average interest rate, inclusive of designated interest rate swap contracts, of 2.69% as of December 31, 2021 (as of December 31, 2020: 2.88%). Based on the variable rate debt in our debt instruments as of December 31, 2021 including the impact of the interest rate swap contract discussed below, a change in interest rates of 1% would result in an increase or a decrease of our annual interest expense of approximately $0.3 million.

Foreign Exchange Rate Risks

Our sales to customers are denominated in U.S. Dollars but our sales to international customers may be denominated in a foreign currency, which exposes us to foreign currency fluctuations. As of December 31, 2021, the Partnership had no outstanding balances denominated in a foreign currency.

Commodity Price Risks

Energy costs represent a large part of our cost of products sold. Natural gas is a large component of that expense. We purchase natural gas primarily from two suppliers: BP Energy and Castleton. The purchase price we pay does not include the cost of transportation so we must arrange and pay for the cost of transporting the natural gas from the gas compressor facility approximately 20 miles from the plant to our facility. We have a separate contract for the transportation of gas. We pay a fixed amount to reserve capacity on a daily basis. In order to mitigate the risk of gas price fluctuations, we hedge a portion of our forecasted natural gas purchases by entering into physical or financial gas hedges generally ranging between 20% and 80% of our expected monthly gas requirements, on a sliding scale, for approximately the next three years. We can give no assurance that we will continue this practice. Historically, we have taken physical delivery under our physical gas contract and we intend to take physical delivery in the future. In addition, to manage our exposure to fluctuating natural gas prices, we enter into financial gas forward purchase contracts. We generally designate our financial gas forward contracts with financial counter-parties as cash flow hedges. Any outstanding contracts are valued at market with the offset going to other comprehensive income (loss), and any material hedge ineffectiveness is recognized in cost of goods sold. Any gain or loss is recognized in cost of goods sold in the same period or periods during which the hedged transaction affects earnings. The aggregate notional value of our financial gas forward purchase contracts as of December 31, 2021 was $24.1 million and net fair value asset was $6.4 million. As of December 31, 2020, the aggregate notional value and fair value liability were $25.9 million and $1.4 million, respectively.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Partners of

Sisecam Resources LP

Atlanta, Georgia

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Sisecam Resources LP (a majority-owned subsidiary of Sisecam Chemicals Wyoming LLC) and its subsidiary (the "Partnership") as of December 31, 2021 and 2020, the related consolidated statements of operations and comprehensive income, cash flows, and equity for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Partnership as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Partnership's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 14, 2022, expressed an unqualified opinion on the Partnership's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on the Partnership's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Agreements and Transactions with Affiliates – Refer to Notes 1, 9, 14, and 15 to the financial statements

Critical Audit Matter Description

The Partnership is both a subsidiary and investee within two different global group structures and agreements directly between the Partnership and affiliates, or indirectly between affiliates that the Partnership does not control, can have a significant impact on recorded amounts or disclosures in the Partnership's financial statements, including any commitments and contingencies between the Partnership and affiliates or, potentially, third parties. Performing audit procedures to evaluate the Partnership’s identification of upstream affiliate relationships, transactions, and commitments and contingencies originating outside of the Ciner Enterprises, Inc. group and the impact of such matters on the financial statements represents a critical audit matter because of the increased auditor judgment necessary to perform audit procedures related to these matters and evaluate the results of those procedures.

How the Critical Audit Matter Was Addressed in the Audit

Table of Contents

Our audit procedures related to the Partnership’s identification of upstream affiliate relationships, transactions, and commitments and contingencies originating outside of the Ciner Enterprises, Inc. group and the impact of such matters on the financial statements included the following, among others:

a.We tested the effectiveness of controls over the Partnership’s affiliate process, including controls over the identification of the Partnership’s affiliate relationships, transactions, and commitments and contingencies originating outside of the Ciner Enterprises, Inc. group.

b.We read publicly available financial filings and news sources related to the Partnership and its affiliates outside of the Ciner Enterprises, Inc. group and listened to the Partnership’s quarterly investor relations calls for information related to potential new affiliates and transactions between the Partnership and affiliates.

c.We inspected director and executive officer questionnaires from the Partnership’s directors and officers to identify any affiliate matters.

d.We searched the general ledger for potential transactions with affiliates.

e.We read significant new or amended agreements and contracts of the Partnership to identify new affiliate relationships, transactions, or commitments and contingencies, and evaluated management’s analyses regarding the accounting and disclosure of such arrangements.

f.We inquired of executive officers, key members of management, and the Audit Committee of the Board of Directors regarding affiliate relationships, transactions and commitments and contingencies.

g.We confirmed with the Partnership’s ultimate parent companies that the affiliate relationships, transactions, and commitments and contingencies identified and disclosed by the Partnership were complete.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. GENERAL

Nature of Operations

As used in this Report, the terms “Sisecam Resources LP,” “the Partnership,” “SIRE,” “we,” “us,” or “our” may refer to Sisecam Resources LP, a publicly traded Delaware limited partnership formed in April 2013 by both Sisecam Chemicals Wyoming LLC (“SCW LLC”), a wholly-owned subsidiary of Sisecam Chemicals Resources LLC (“Sisecam Chemicals”) and Sisecam Resource Partners LLC (our “general partner” or “Sisecam GP”), a wholly-owned subsidiary of SCW LLC. Sisecam Chemicals is 60% owned by Sisecam Chemicals USA Inc. (“Sisecam USA”) and 40% owned by Ciner Enterprises Inc. (“Ciner Enterprises”). Sisecam USA is a direct subsidiary of Türkiye Sise ve Cam Fabrikalari A.S (“Şişecam Parent”) which is an approximately 51%-owned subsidiary of Turkiye Is Bankasi Turkiye Is Bankasi ("Isbank").

Şişecam Parent is a global company operating in soda ash, chromium chemicals, flat glass, auto glass, glassware glass packaging and glass fiber sectors and is based in Turkey and is listed on the Istanbul exchange. Ciner Enterprises Inc. is a direct wholly-owned subsidiary of WE Soda Ltd., a U.K. Corporation (“WE Soda”). WE Soda is a direct wholly-owned subsidiary of KEW Soda Ltd., a U.K. corporation (“KEW Soda”), which is a direct wholly-owned subsidiary of Akkan Enerji ve Madencilik Anonim Şirketi (“Akkan”). Akkan is directly and wholly owned by Turgay Ciner, the Chairman of the Ciner Group (“Ciner Group”), a Turkish conglomerate of companies engaged in energy and mining (including soda ash mining), media and shipping markets.

Sisecam Wyoming LLC (“Sisecam Wyoming”) is in the business of mining trona ore to produce soda ash, and is a 51.0% majority-owned subsidiary of the Partnership. The Partnership’s operations consist solely of its investment in Sisecam Wyoming. NRP Trona LLC, a wholly owned subsidiary of Natural Resource Partners L.P. (“NRP”), currently owns a 49.0% membership interest in Sisecam Wyoming. NRP’s membership interest in Sisecam Wyoming is reflected as the noncontrolling interest in the Partnership’s financial results.

All of our soda ash processed is currently sold to various domestic and international customers. Sisecam Chemicals is the exclusive sales agent for the Partnership. Sisecam Chemicals has leveraged the distributor network established by Ciner Group while independently reviewing current and potential distribution partners to optimize the Partnership’s reach into each market.

partnership status of the Partnership or any of its subsidiaries. As a result of Sisecam USA’s and Ciner Enterprise’s respective interests in Sisecam Chemicals and their respective rights under the Sisecam Chemicals Operating Agreement, each of Ciner Enterprises and Sisecam USA and their respective beneficial owners may be deemed to share beneficial ownership of the approximate 2% general partner interest in the Partnership and approximately 74% of the common units in the Partnership owned directly by SCW LLC and indirectly by Sisecam Chemicals as parent entity of SCW LLC.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Significant Accounting Policies

The accompanying consolidated financial statements of the Partnership and its subsidiary have been prepared in conformity with U.S. generally accepted accounting principles and reflect all adjustments, consisting of normal recurring accruals, which are necessary for fair presentation of the results of operations, financial position and cash flows for the periods presented. All significant intercompany transactions, balances, revenue and expenses have been eliminated in consolidation and unless otherwise noted, the financial information for the Partnership is presented before noncontrolling interest.

Use of Estimates

The preparation of consolidated financial statements, in accordance with accounting principles generally accepted in the United States of America, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Furthermore, we considered the impact of the COVID-19 pandemic on the use of estimates and assumptions used for financial reporting. While our year-to-date production has recovered from the negative impact of the COVID-19 pandemic, given we cannot predict the duration or the scope of the COVID-19 pandemic and its impact on our operations, the potential negative financial impact to our results cannot be reasonably estimated but could be material. As a result of these uncertainties, actual results could differ from those estimates and assumptions. If the economy or markets in which we operate become weaker than pre-COVID-19 levels, our business, financial condition and results of operations might be materially and adversely impacted.

Revenue Recognition

The majority of the Partnership’s revenues are recognized upon satisfaction of our performance obligations, that is, delivery and transfer of title to the product to our customers as discussed below. Additionally, the Partnership has made an accounting policy election to account for shipping and handling activities as fulfillment costs. We have one reportable segment and our revenue is derived from the sale of soda ash which is our sole and primary good and service.

Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. At contract inception, we assess the goods and services promised in contracts with customers and identify performance obligations for each promise to transfer to the customer, a good or service that is distinct. To identify the performance obligations, the Partnership considers all goods and services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. From its analysis, the Partnership determined that the sale of soda ash is currently its only performance obligation. Many of our customer volume commitments are short-term and our performance obligations for the sale of soda ash are generally limited to single purchase orders.

•When performance obligations are satisfied. Substantially all of our revenue is recognized at a point-in-time when control of goods transfers to the customer.

•Transfer of Goods. The Partnership uses standard shipping terms across each customer contract with very few exceptions. Control transfer occurs at the point at which the customer has the ability to direct the use of and obtain substantially all remaining benefits from the asset. The time at which delivery and transfer of title, and therefore control, occurs is the point when the product leaves our facilities for domestic customers, the point when the product reaches the port of loading for ANSAC sales, and the point when the product is placed on a vessel for other international customers, thereby rendering our performance obligation fulfilled. Until the ANSAC exit on December 31, 2020, the time at which delivery and transfer of title occurred for ANSAC sales had been the same as domestic customers.

•Payment Terms. Our payment terms vary by the type and location of our customers. The term between invoicing and when payment is due is not significant and consistent with typical terms in the industry.

•Variable Consideration. We recognize revenue as the amount of consideration that we expect to receive in exchange for transferring promised goods or services to customers. We do not adjust the transaction price for the effects of a significant financing component, as the time period between control transfer of goods and services and expected payment is one year or less. At the time of sale, we estimate provisions for different forms of variable consideration (discounts, rebates, and pricing adjustments) based on historical experience, current conditions and contractual obligations, as applicable. The estimated

Table of Contents

transaction price is typically not subject to significant reversals. We adjust these estimates when the most likely amount of consideration we expect to receive changes, although these changes are typically immaterial.

•Returns, Refunds and Warranties. In the normal course of business, the Partnership does not accept returns, nor does it typically provide customers with the right to a refund.

•Freight. In accordance with FASB Accounting Standard Codification, Revenue from Contracts with Customers (Topic 606) (“ASC 606”), the Partnership made a policy election to treat freight and related costs that occur after control of the related good transfers to the customer as fulfillment activities instead of separate performance obligations. Therefore, freight is recognized at the point in which control of soda ash has transferred to the customer.

Revenue Disaggregation. In accordance with ASC 606-10-50, the Partnership disaggregates revenue from contracts with customers into geographical regions. The Partnership determined that disaggregating revenue into these categories achieved the disclosure objectives to depict how the nature, timing, amount and uncertainty of revenue and cash flows are affected by economic factors. Refer to Note 16, “Major Customers and Segment Reporting,” for revenue disaggregated into geographical regions.

Revenue Contract Balances. The timing of revenue recognition, billings and cash collections results in billed receivables, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities).

•Contract Assets. At the point of shipping, the Partnership has an unconditional right to payment generally that is only dependent on the passage of time. In general, customers are billed and a receivable is recorded as goods are shipped. These billed receivables are reported as “Accounts Receivable, net” on the Consolidated Balance Sheets as of December 31, 2021 and December 31, 2020. There were no contract assets as of December 31, 2021 and December 31, 2020.

•Contract Liabilities. There may be situations where customers are required to prepay for freight and insurance prior to shipment. The Partnership accounts for freight costs as fulfillment activities and therefore, such prepayments are considered a part of the single obligation to provide soda ash. In such instances, a contract liability for prepaid freight will be recorded.

Freight Costs

The Partnership includes freight costs billed to customers for shipments administered by the Partnership in gross sales. The related freight costs incurred by the Partnership along with cost of products sold are deducted from gross sales to determine gross profit.

Cash and Cash Equivalents

The Partnership considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents consist primarily of money market deposit accounts.

Accounts Receivable

We determine expected credit losses for recorded receivables based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount.

Inventory

Inventory is carried at the lower of cost and net realizable value. Cost is determined using the first-in, first-out method for raw material and finished goods inventory and the weighted average cost method for stores inventory. Costs include raw materials, direct labor and manufacturing overhead. Net realizable value is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.

•Raw material inventory includes material, chemicals and natural resources being used in the mining and refining process.

•Finished goods inventory is the finished product soda ash.

•Stores inventory includes parts, materials and operating supplies which are typically consumed in the production of soda ash and currently available for future use. If the inventory has been used within the preceding twelve months, it is classified as current assets and remainder is classified as non-current assets.

Table of Contents

Property, Plant, and Equipment

Property, plant, and equipment are stated at cost less accumulated depreciation. Depreciation is computed over the estimated useful lives of depreciable assets, using the straight-line method. The estimated useful lives applied to depreciable assets are as follows:


						Useful Lives
Land improvements						10 years
Depletable land						15-60 years
Buildings and building improvements						10-30 years
Computer hardware						3-5 years
Machinery and equipment						5-20 years
Furniture and fixtures						5-10 years

Mineral reserves are amortized over an estimated time period that is derived from total estimated proven and probable mineral reserves divided by our average annual tons mined which was over 50 years as of December 31, 2021.

The Partnership’s policy is to evaluate property, plant, and equipment for impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. An indicator of potential impairment would include situations when the estimated future undiscounted cash flows are less than the carrying value. The amount of any impairment then recognized would be calculated as the difference between estimated fair value and the carrying value of the asset.

Derivative Instruments and Hedging Activities

The Partnership may enter into derivative contracts from time to time to manage exposure to the risk of exchange rate changes on its foreign currency transactions, the risk of changes in natural gas prices, and the risk of the variability in interest rates on borrowings. Gains and losses on derivative contracts qualifying for hedge accounting are reported as a component of the underlying transactions. The Partnership follows hedge accounting for its hedging activities. All derivative instruments are recorded on the balance sheet at their fair values. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. The Partnership designates its derivatives based upon criteria established for hedge accounting under generally accepted accounting principles. For a derivative designated as a fair value hedge, the gain or loss is recognized in earnings in the period of change together with the offsetting gain or loss on the hedged item attributed to the risk being hedged. For a derivative designated as a cash flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of accumulated other comprehensive income (loss) and subsequently reclassified into earnings when the hedged exposure affects earnings. Any significant ineffective portion of the gain or loss is reported in earnings immediately. For derivatives not designated as hedges, the gain or loss is reported in earnings in the period of change. When the Partnership has natural gas physical forward contracts, they are accounted for under the normal purchases and normal sales scope exception.

Income Tax

We are organized as a pass-through entity for federal income tax purposes and therefore are not subject to federal or certain state income taxes. As a result, our partners are responsible for income taxes based on their respective share of taxable income. Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the partnership agreement.

Reclamation Costs

The Partnership is obligated to return the land beneath its refinery and tailings ponds to its natural condition upon completion of operations and is required to return the land beneath its rail yard to its natural condition upon termination of the various lease agreements.

The Partnership accounts for its land reclamation liability as an asset retirement obligation, which requires that obligations associated with the retirement of a tangible long-lived asset be recorded as a liability when those obligations are incurred, with the amount of the liability initially measured at fair value. Upon initially recognizing a liability for an asset retirement obligation, an entity must capitalize the cost by recognizing an increase in the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the estimated useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement.

The estimated original liability calculated in 1996 for the refinery and tailing ponds was calculated based on the estimated useful life of the mine, which was 80 years, and on external and internal estimates as to the cost to restore the land in the future and

Table of Contents

state regulatory requirements. The liability was discounted using a weighted average credit-adjusted risk-free rate of approximately 6% and is being accreted throughout the estimated life of the related assets to equal the total estimated costs with a corresponding charge being recorded to cost of products sold.

The Partnership has constructed a rail yard to facilitate loading and switching of rail cars. The Partnership is required to restore the land on which the rail yard is constructed to its natural conditions. The original estimated liability for restoring the rail yard to its natural condition was calculated based on the land lease life of 30 years and on external and internal estimates as to the cost to restore the land in the future. The liability is discounted using a credit-adjusted risk-free rate of 4.2% and is being accreted throughout the estimated life of the related assets to equal the total estimated costs with a corresponding charge being recorded to cost of products sold.

Fair Value of Financial Instruments

Fair value is determined using a valuation hierarchy, generally by reference to an active trading market, quoted market prices or model-derived valuations for the same or similar financial instruments. See Note 17, “Fair Value Measurements,” for more information.

Equity-Based Compensation

We recognize compensation expense related to equity-based awards, with service conditions, granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The grant date fair value of the equity-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. Equity-based awards with market conditions are fair valued using a Monte Carlo Simulation model. See Note 12, “Equity-Based Compensation,” for additional information.

Fair value measurements

The Partnership measures certain financial and non-financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. Fair value disclosures are reflected in a three-level hierarchy, maximizing the use of observable inputs and minimizing the use of unobservable inputs.

A three-level valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows:


			Level 1-inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market.

			Level 2-inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability.

			Level 3-inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability.

Financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, derivative financial instruments and long-term debt. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable and accrued expenses approximate their fair value because of the nature of such instruments. Our long-term debt and derivative financial instruments are measured at their fair values with Level 2 inputs based on quoted market values for similar but not identical financial instruments.

Subsequent Events

We have evaluated subsequent events through the filing of this Annual Report on Form 10-K. See Note 18, “Subsequent Events” for additional information.

Recent Accounting Guidance

Recently Adopted Accounting Guidance

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”) providing temporary guidance to ease the potential burden in accounting for reference rate reform primarily resulting from the discontinuation of the London Inter-bank Offered Rate (“LIBOR”), which occurred on December 31, 2021 except U.S. Dollar LIBOR, which is expected to occur on June 30, 2023. The amendments in ASU 2020-04 are elective and apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another

Table of Contents

reference rate expected to be discontinued. The new guidance provides the following optional expedients: (i) simplifies accounting analyses under current GAAP for contract modifications; (ii) simplifies the assessment of hedge effectiveness and allows hedging relationships affected by reference rate reform to continue; and (iii) allows a one-time election to sell or transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform. An entity may elect to apply the amendments prospectively from March 12, 2020 through December 31, 2022 by accounting topic. The Partnership evaluated ASU 2020-04 and concluded that there was no impact to the Partnership’s consolidated financial statements.

In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”) to clarify that all derivative instruments affected by changes to the interest rates used for discounting, margining or contract price alignment (commonly referred to as the discounting transition) are in the scope of ASC 848. The amendments also clarify other aspects of the guidance in ASC 848 and addresses the effects of the cash compensation adjustment provided in the discounting transition on certain aspects of hedge accounting. The guidance in ASC 848 also allows entities to make a one-time election to sell and/or transfer to available for sale or trading any held-to-maturity debt securities that refer to an interest rate affected by reference rate reform and were classified as held to maturity before January 1, 2020. The original guidance and the recently issued ASU are effective as of their issuance dates. The relief provided is temporary and generally cannot be applied to contract modifications that occur after December 31, 2022 or hedging relationships entered into or evaluated after that date. However, the FASB has indicated that it will revisit the sunset date in ASC 848 after the LIBOR administrator makes a final decision on a phaseout date. The LIBOR administrator recently extended the publication of the overnight and the one-, three-, six- and 12-month U.S. Dollar LIBOR settings through June 30, 2023, when many existing contracts that reference LIBOR will have expired. The Partnership evaluated ASU 2021-01 and concluded that there was no impact to the Partnership’s consolidated financial statements.

3. NET INCOME PER UNIT AND CASH DISTRIBUTION

Allocation of Net Income

Our net income is allocated to the general partner and limited partners in accordance with their respective partnership percentages, after giving effect to priority income allocations for incentive distributions, if any, to our general partner, pursuant to our partnership agreement. Net income per unit applicable to limited partners is computed by dividing limited partners’ interest in net income attributable to Sisecam Chemicals, after deducting the general partner’s interest and any incentive distributions, by the weighted average number of outstanding common units. Earnings in excess of distributions are allocated to the general partner and limited partners based on their respective ownership interests. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income allocations used in the calculation of net income per unit.

In addition to the common units, we have also identified the general partner interest and incentive distribution rights (“IDRs”) as participating securities and use the two-class method when calculating the net income per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Anti-dilutive units outstanding were immaterial for all periods presented.

The net income attributable to common unitholders and the weighted average units for calculating basic and diluted net income per common units were as follows:

Quarterly Distribution

Our general partner has considerable discretion in determining the amount of available cash, the amount of distributions and the decision to make any distribution. Although our partnership agreement requires that we distribute all of our available cash quarterly, there is no guarantee that we will make quarterly cash distributions to our unitholders at our current quarterly distribution level, at the minimum quarterly distribution level or at any other rate, and we have no legal obligation to do so.

The following table illustrates the total amount of available cash from operating surplus for the quarter ended December 31, 2021 that was distributed to the unitholders of limited partners and the general partner, including in respect of incentive distribution rights.


(In thousands)			Cash Distributions to General Partner

	$	12,861	$	265	$	303	$	568	$	13,430

General Partner Interest and Incentive Distribution Rights

Our partnership agreement provides that our general partner initially will be entitled to approximately 2.0% of all distributions that we make prior to our liquidation. Our general partner has the right, but not the obligation, to contribute up to a proportionate amount of capital to us in order to maintain its approximately 2.0% general partner interest if we issue additional units. Our general partner’s approximate 2.0% interest, and the percentage of our cash distributions to which our general partner is entitled from such approximate 2.0% interest, will be proportionately reduced if we issue additional units in the future (other than the issuance of common units upon a reset of the IDRs), and our general partner does not contribute a proportionate amount of capital to us in order to maintain its approximate 2.0% general partner interest. Our partnership agreement does not require that our general partner fund its capital contribution with cash. It may, instead, fund its capital contribution by contributing to us common units or other property.

IDRs represent the right to receive increasing percentages (13.0%, 23.0% and 48.0%) of quarterly distributions from operating surplus after we have achieved the minimum quarterly distribution and the target distribution levels. Our general partner currently holds the IDRs, but may transfer these rights separately from its general partner interest, subject to certain restrictions in our partnership agreement.

Percentage Allocations of Distributions from Operating Surplus

Table of Contents

The following table illustrates the percentage allocations of distributions from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under the column heading "Marginal Percentage Interest in Distributions" are the percentage interests of our general partner and the unitholders in any distributions from operating surplus we distribute up to and including the corresponding amount in the column "Total Quarterly Distribution per Unit Target Amount." The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution apply to quarterly distribution amounts for the fourth quarter of 2021. Under the Partnership agreement, our general partner has considerable discretion to determine the amount of available cash (as defined therein) for distribution each quarter to the Partnership’s unitholders, including discretion to establish cash reserves that would limit the amount of available cash eligible for distribution to the Partnership’s unitholders for any quarter. The Partnership does not guarantee that it will pay the target amount of the minimum quarterly distribution listed below (or any distributions) on its units in any quarter. The percentage interests set forth below for our general partner (1) include a 2.0% general partner interest, (2) assume that our general partner has contributed any additional capital necessary to maintain its 2.0% general partner interest, (3) assume that our general partner has not transferred its incentive distribution rights and (4) assume that we do not issue additional classes of equity securities.


		Marginal Percentage Interest in Distributions
	Total Quarterly Distribution per Unit Target Amount	Unitholders		General Partner		Incentive Distributions Rights
Minimum Quarterly Distribution	$0.5000	98.0	%	2.0	%	—	%
First Target Distribution	above $0.5000 up to $0.5750	98.0	%	2.0	%	—	%
Second Target Distribution	above $0.5750 up to $0.6250	85.0	%	15.0	%	13.0	%
Third Target Distribution	above $0.6250 up to $0.7500	75.0	%	25.0	%	23.0	%
Thereafter	above $0.7500	50.0	%	50.0	%	48.0	%

4. ACCOUNTS RECEIVABLE, NET

Accounts receivable, net consisted of the following as of December 31:


(In millions)	2021		2020
Trade receivables, net	$	109.8	$	32.6
Other receivables	7.1		8.0
Total	$	116.9	$	40.6

The increase in trade receivables, net of allowances, at December 31, 2021 compared to December 31, 2020, is primarily due to the receivables from ANSAC being included in the balance at December 31, 2021, while classified as accounts receivable (affiliates) at December 31, 2020, as well as more sales in the three months ended December 31, 2021 compared to the same period ended December 31, 2020.

5. INVENTORY

Inventory consisted of the following as of December 31:


(In millions)	2021		2020
Raw materials	$	10.5	$	9.9
Finished goods	9.3		13.4
Stores inventory, current	10.3		10.2
Total	$	30.1	$	33.5

The decrease in finished goods inventory at December 31, 2021 compared to December 31, 2020 is primarily due to the buildup of inventory to facilitate Sisecam Chemicals’ exit from ANSAC on December 31, 2020.

Total property, plant, and equipment, net	$	304.2	$	307.4

Depreciation, depletion and amortization expense on property, plant, and equipment was $30.7 million, $28.1 million, and $26.9 million for the years ended December 31, 2021, 2020, and 2019, respectively.

The increase in construction in progress from December 31, 2020 to December 31, 2021 is due to the construction of mine ventilation and housing for the switchgear.

7. OTHER NON-CURRENT ASSETS

Other non-current assets consisted of the following as of December 31:


(In millions)	2021		2020
Stores inventory, non-current	$	20.5	$	18.6
Internal-use software, net of accumulated amortization	5.7		5.7
Other	4.9		1.1
Total	$	31.1	$	25.4

During the years ended December 31, 2021, 2020, and 2019, in accordance with ASC 350-40, Internal-Use Software, we capitalized $0.9 million, $0.5 million and $0.6 million, respectively, of certain internal use software development costs. Software development activities generally consist of three stages (i) the research and planning stage, (ii) the application and infrastructure development stage, and (iii) the post-implementation stage. Costs incurred in the planning and post-implementation stages of software development, or other maintenance and development expenses that do not meet the qualification for capitalization are expensed as incurred. Costs incurred in the application and infrastructure development stage, including significant enhancements and upgrades, are capitalized. The Partnership amortizes software development costs on a straight-line basis over the estimated useful life of five to ten years under depreciation and amortization expense which is included in the cost of products sold financial statement line item of the consolidated statements of operations. During the years ended December 31, 2021, 2020, and 2019, we amortized internal use software development costs of $0.9 million, $0.7 million and $0.7 million, respectively. Amortization for these internal use software development costs are expected to be $0.8 million per year.

Sisecam Wyoming Equipment Financing Arrangement

Master Loan and Security Agreement:

On March 26, 2020, Sisecam Wyoming and Banc of America Leasing & Capital, LLC, as lender (the “Equipment Financing Lender”), entered into an equipment financing arrangement (“Sisecam Wyoming Equipment Financing Arrangement”), including a Master Loan and Security Agreement, dated as of March 25, 2020 (as amended, the “Master Agreement”) and an Equipment Security Note Number 001, dated as of March 25, 2020 (the “Sisecam Wyoming Equipment Financing Arrangement Security Note Number 001,” or the “Initial Secured Note”), which provides the terms and conditions for the debt financing of certain equipment related to Sisecam Wyoming’s natural gas-fired turbine co-generation facility that became operational in March 2020. Each equipment financing entered into under the Sisecam Wyoming Equipment Financing Arrangement will be evidenced by the execution of one or more equipment notes (including the Initial Secured Note) that incorporate the terms and conditions of the Master Agreement (each, an “Equipment Note”). In order to secure the payment and performance of Sisecam Wyoming’s obligations under the Sisecam Wyoming Equipment Financing Arrangement, Sisecam Wyoming granted to the Equipment Financing Lender a continuing security interest in all of Sisecam Wyoming’s right, title and interest in and to the Equipment (as defined in the Master Agreement) and certain related collateral.

On October 28, 2021, in connection with the entry into the Sisecam Wyoming Credit Facility (which replaced the Prior Sisecam Wyoming Credit Facility), Sisecam Wyoming and the Equipment Financing Lender entered into an amendment to the Master Agreement, in order to amend and restate all covenants that are based upon a specified level or ratio relating to assets, liabilities, indebtedness, rentals, net worth, cash flow, earnings, profitability, or any other accounting-based measurement or test to conform with the Sisecam Wyoming Credit Facility.

On December 17, 2021, Sisecam Wyoming and the Equipment Financing Lender entered into Amendment Number 001 to the Initial Secured Note (“First Amendment to the Initial Secured Note”). The First Amendment to the Initial Secured Note, provides among other things: (i) upon the occurrence of an early full payoff of the Second Secured Note (as defined below), Sisecam Wyoming shall simultaneously pay, in full, the outstanding amount of the Initial Secured Note and (ii) Sisecam Wyoming grants to Equipment Financing Lender a security interest in all collateral securing the Second Secured Note to secure Sisecam Wyoming’s obligations under the Initial Secured Note.

Upon the occurrence of an event of default, in its discretion, the Equipment Financing Lender may exercise certain remedies, including, among others, the ability to accelerate the maturity of any Equipment Note such that all amounts thereunder will become immediately due and payable, to take possession of the Equipment identified in any Equipment Note, and to charge Sisecam Wyoming a default rate of interest on all then outstanding or thereafter incurred obligations under the Sisecam Wyoming Equipment Financing Arrangement:

Among other things, Security Note Number 001:

In connection with the Second Sisecam Wyoming Amendment (as defined below), the Master Agreement was amended to incorporate, among other things, the modified covenants set forth in the Second Sisecam Wyoming Amendment related to consolidated leverage ratios of Sisecam Wyoming.

In December 2021 a waiver was obtained to accommodate the CoC Transaction.

First Amendment to Security Note Number 001:

On December 17, 2021, Sisecam Wyoming and the Equipment Financing Lender entered into Amendment Number 001 to the Initial Secured Note (“First Amendment to the Initial Secured Note”).

•upon the occurrence of full payoff of Initial Secured Note dated as of March 25, 2020 under the Master Agreement, Sisecam Wyoming shall simultaneously pay, in full, the outstanding amount of this Second Secured Note.

Sisecam Wyoming Credit Facility

On October 28, 2021, Sisecam Wyoming entered into a new $225.0 million senior secured revolving credit facility (the “Sisecam Wyoming Credit Facility”) with each of the lenders listed on the respective signature pages thereof and Bank of America, N.A., as administrative agent, swing line lender and letter of credit issuer. The Sisecam Wyoming Credit Facility matures on October 28, 2026. On closing, the amount drawn under this new Sisecam Wyoming Credit Facility approximated the amount outstanding under the Prior Sisecam Wyoming Credit Facility at September 30, 2021.

The Sisecam Wyoming Credit Facility provides, among other things:

•a sublimit up to $40.0 million for the issuance of standby letters of credit and a sublimit up to $20.0 million for swingline loans;

•contains various covenants and restrictive provisions that limit (subject to certain exceptions) Sisecam Wyoming’s ability to: (i) incur certain liens or permit them to exist; (ii) incur or guarantee additional indebtedness; (iii) make certain investments and acquisitions related to Sisecam Wyoming’s operations in Wyoming); (iv) merge or consolidate with another company; (v) transfer, sell or otherwise dispose of assets, (vi) make distributions; (vii) change the nature of Sisecam Wyoming’s business; and (viii) enter into certain transactions with affiliates;

•a requirement to maintain a quarterly consolidated interest coverage ratio of not less than 3.00:1.00; and

Table of Contents

In addition, loans under the Sisecam Wyoming Credit Facility (other than any swingline loans) will bear interest at Sisecam Wyoming’s option at either:

•a base rate, which equals the highest of (i) Bank of America’s prime rate, (ii) the federal funds rate then in effect on such day, plus 0.50%; (iii) one-month Bloomberg Short-Term Bank Yield Index (“BSBY”) adjusted daily rate, plus 1.0%; and (iv) 1.0%, plus, in each case, an applicable margin range from 0.50% to 1.75% based on the consolidated leverage ratio of Sisecam Wyoming; or

•a BSBY rate for interest periods of one, three or six months, plus, in each case, an applicable margin range from 1.50% to 2.75% based on the consolidated leverage ratio of Sisecam Wyoming.

In addition, if a BSBY rate ceases to exist for any period, loans under the Sisecam Wyoming Credit Facility will bear interest based on alternative indexes (including the secured overnight financing rate), plus an applicable margin.

The unused portion of the Sisecam Wyoming Credit Facility is subject to a per annum commitment fee and the applicable margin of the interest rate under the Sisecam Wyoming Credit Facility will be determined as follows:


Pricing Tier	Leverage Ratio	BSBY Rate Loans	Base Rate Loans	Commitment Fee
1	< 1.25:1.0	1.500%	0.500%	0.225%
2	≥ 1.25:1.0 but < 1.75:1.0	1.750%	0.750%	0.250%
3	≥ 1.75:1.0 but < 2.25:1.0	2.000%	1.000%	0.275%
4	≥ 2.25:1.0 but < 3.00:1.0	2.250%	1.250%	0.300%
5	≥ 3.00:1.0 but < 3.50:1.0	2.500%	1.500%	0.325%
6	≥ 3.50:1.0	2.750%	1.750%	0.350%

The Sisecam Wyoming Credit Facility permits the consolidated leverage ratio as of the end of each fiscal quarter of Sisecam Wyoming, commencing with the fiscal quarter ending December 31, 2021, to be greater than 3.25: 1.0; provided, however, during the Specified Capital Expansion Holiday, the lenders shall not permit the consolidated leverage ratio as of the end of each fiscal quarter of Sisecam Wyoming to be greater than 3.75:1.00. “Specified Capital Expansion Holiday” means the period consisting of four (4) full fiscal quarters after the Sisecam Wyoming has (i) made capital expenditures related to the Specified Capital Expansion (or other capital expansion project approved by the board of directors, board of managers or equivalent governing body of Sisecam Wyoming) of at least $200.0 million and (ii) provided written notice to the administrative agent that Sisecam Wyoming is electing to initiate such Specified Capital Expansion Holiday. “Specified Capital Expansion” means expansion activities related to the lenders’ soda ash operations in Wyoming which have been approved in writing by the Sisecam Wyoming’s board of directors, board of managers or equivalent governing body. The Sisecam Wyoming Credit Facility permits the consolidated interest coverage ratio as of the end of any fiscal quarter of Sisecam Wyoming, commencing with the fiscal quarter ending December 31, 2021, to be less than 3.00:1.00.

In connection with the CoC Transaction (as defined in Note 1 above), on December 17, 2021, Sisecam Wyoming entered into the First Amendment (“First Amendment”) to its $225.0 million senior secured revolving credit facility, dated as of October 28, 2021 (as amended, the “Sisecam Wyoming Credit Facility”), with each of the lenders listed on the respective signature pages thereof and Bank of America, N.A., as administrative agent, swing line lender and letter of credit issuer. Pursuant to the First Amendment, the definition of “Change of Control” under the Credit Facility was revised to reflect that the updated indirect ownership of Sisecam Resources LP and Sisecam GP as contemplated by the CoC Transaction will not cause a Change of Control under the Sisecam Wyoming Credit Facility so long as the CoC Transaction occurs prior to March 31, 2022. The CoC Transaction did not cause a change in control event under the Credit Facility.

Management is not aware of any current circumstances that would result in an event of default under the Sisecam Wyoming Credit Facility at December 31, 2021 or in the next twelve months.

Prior Sisecam Wyoming Credit Facility

On August 1, 2017, Sisecam Wyoming entered into a credit agreement (as amended, the “Prior Sisecam Wyoming Credit Facility” and together with the Sisecam Wyoming Equipment Financing Arrangement, the “Prior Sisecam Wyoming Debt Agreements”) with each of the lenders listed on the respective signature pages thereof and PNC Bank, National Association (“PNC Bank”), as administrative agent, swing line lender and a Letter of Credit (“L/C”) issuer. The Prior Sisecam Wyoming Credit Facility was a $225.0 million senior revolving credit facility with a syndicate of lenders, which matured on the fifth anniversary of the closing date of such credit facility. The Prior Sisecam Wyoming Credit Facility provided for revolving loans to fund working capital requirements, and capital expenditures, to consummate permitted acquisitions and for all other lawful partnership purposes. The Prior Sisecam Wyoming Credit Facility had an accordion feature that allowed Sisecam Wyoming to increase the available revolving borrowings under the facility by up to an additional $75.0 million, subject to Sisecam Wyoming receiving increased commitments

Table of Contents

from existing lenders or new commitments from new lenders and the satisfaction of certain other conditions. In addition, the Prior Sisecam Wyoming Credit Facility includes a sublimit up to $20.0 million for same-day swing line advances and a sublimit up to $40.0 million for letters of credit.

On July 27, 2020, the Prior Sisecam Wyoming Credit Facility was further amended (the “July 2020 Sisecam Wyoming Amendment”) to increase Sisecam Wyoming’s financial and liquidity flexibility due to COVID-19. The July 2020 Sisecam Wyoming Amendment, among other things, (i) increased, for a limited period, certain restrictive debt covenants that require Sisecam Wyoming and its subsidiaries to maintain certain leverage ratios and interest coverage ratios at the end of each period, (ii) provided a tiered interest rate structure based on applicable covenant ratios and established a 0.5% interest floor, (iii) effectuated changes to collateral restricted disbursements and covenanted to give security if covenant ratios are equal to or above certain levels. The July 2020 Sisecam Wyoming Amendment also provided for covenants to restrict certain payments and to give security in certain personal property of Ciner Wyoming following a fiscal quarter in which the leverage ratio is equal to or higher than 3.50:1.0, so long as the applicable leverage ratio limit is otherwise adhered to. Any such security would be released upon achievement of a leverage ratio less than 2.00:1.0 at the end of any quarter.

In addition, the Prior Sisecam Wyoming Credit Facility contained various covenants and restrictive provisions that limit (subject to certain exceptions) Sisecam Wyoming’s ability to:

•make distributions on or redeem or repurchase units;

•incur or guarantee additional debt;

•make certain investments and acquisitions;

•incur certain liens or permit them to exist;

•enter into certain types of transactions with affiliates of Sisecam Wyoming;

•merge or consolidate with another company; and

•transfer, sell or otherwise dispose of assets.

The July 2020 Sisecam Wyoming Amendment also required quarterly maintenance of a certain leverage ratio and an interest coverage ratio of not less than 3.00:1.0. On October 28, 2021, Sisecam Wyoming terminated the Prior Sisecam Wyoming Credit Facility and entered into the Sisecam Wyoming Credit Facility as described above.

Ciner Resources Credit Facility

On August 1, 2017, the Partnership entered into a Credit Agreement (as amended, the “Ciner Resources Credit Facility”) with each of the lenders listed on the respective signature pages thereof and PNC Bank, as administrative agent, swing line lender and an L/C issuer. The Ciner Resources Credit Facility was a $10.0 million senior secured revolving credit facility with a syndicate of lenders, that would have matured on the fifth anniversary of the closing date of such credit facility. The Ciner Resources Credit Facility provided for revolving loans to be available to fund distributions on the Partnership’s units and working capital requirements and capital expenditures, to consummate permitted acquisitions and for all other lawful partnership purposes. The Ciner Resources Credit Facility included a sublimit up to $5.0 million for same-day swing line advances and a sublimit up to $5.0 million for letters of credit. The Partnership’s obligations under the Ciner Resources Credit Facility were guaranteed by each of the Partnership’s material domestic subsidiaries other than Sisecam Wyoming. In addition, the Partnership’s obligations under the Ciner Resources Credit Facility were secured by a pledge of substantially all of the Partnership’s assets (subject to certain exceptions), including the membership interests held in Sisecam Wyoming by the Partnership.

On March 8, 2021, the Partnership terminated the Ciner Resources Credit Facility; the Partnership repaid in full its obligations thereunder.

WE Soda and Ciner Enterprises Facilities Agreement

On August 1, 2018, Ciner Enterprises, the entity that, prior to the CoC Transaction, indirectly owned and controlled the Partnership, refinanced its existing credit agreement and entered into a new facilities agreement, to which WE Soda and Ciner Enterprises (as borrowers), and KEW Soda, WE Soda, WE Soda Kimya Yatırımları Anonim Şirketi, Ciner Kimya Yatırımları Sanayi ve Ticaret Anonim Şirketi, Ciner Enterprises, SCW LLC, and Sisecam Chemicals (as original guarantors and together with the borrowers, the “Ciner Obligors”), were parties (as amended and restated or otherwise modified, the “Facilities Agreement”), and certain related finance documents.

On February 20, 2022, the Facilities Agreement was refinanced and Ciner Enterprises, SCW LLC, and Sisecam Chemicals were released from being Obligors of the Facilities Agreement and are not a party to the WE Soda refinanced agreement.

11. EMPLOYEE COMPENSATION

The Partnership participates in various benefit plans offered and administered by Sisecam Chemicals and is allocated its portions of the annual costs related thereto. The specific plans are as follows:

Retirement Plans - Benefits provided under the retirement plans for salaried employees and hourly employees (the “Retirement Plans”) are based upon years of service and average compensation for the highest 60 consecutive months of the employee’s last 120 months of service, as defined. The Retirement Plans cover substantially all full-time employees hired before May 1, 2001. Sisecam Chemicals’ Retirement Plans had a net liability balance of $32.8 million and $55.1 million at December 31, 2021 and December 31, 2020, respectively. Sisecam Chemicals’ current funding policy is to contribute an amount within the range of the minimum required and the maximum tax-deductible contribution. The Partnership’s allocated portion of the Retirement Plans’ net periodic pension (benefit) cost for the years ended December 31, 2021, 2020 and 2019 was $(2.7) million, $(1.3) million and $1.0 million, respectively. The variation in annual pension (benefit) cost was driven by a better-than-expected return on assets and lower interest expense assumptions.

Savings Plan - The 401(k) Retirement Plan (the “401(k) Plan”) covers all eligible hourly and salaried employees. Eligibility is limited to all domestic residents and any foreign expatriates who are in the United States indefinitely. The 401(k) Plan permits employees to contribute specified percentages of their compensation, while the Partnership makes contributions based upon specified percentages of employee contributions. Participants hired on or subsequent to May 1, 2001, will receive an additional contribution from the Partnership based on a percentage of the participant’s base pay. Contributions made to the 401(k) Plan for the years ended December 31, 2021, 2020 and 2019 were $3.4 million, $3.4 million and $3.0 million, respectively.

Postretirement Benefits - Most of the Partnership’s employees hired before January 2, 2017 are eligible for postretirement benefits other than pensions if they reach age 58 while still employed with at least 10 years of service.

The postretirement benefits are accounted for by Sisecam Chemicals on an accrual basis over an employee’s period of service. The postretirement plan, excluding pensions, is not funded, and Sisecam Chemicals has the right to modify or terminate the plan. The post-retirement plan had a net unfunded liability of $10.7 million and $13.1 million on December 31, 2021 and December 31, 2020, respectively.

The Partnership’s allocated portion of postretirement cost (benefit) for the years ended December 31, 2021, 2020 and 2019, was $0.9 million, $1.2 million and $(2.2) million, respectively. The postretirement benefit for the Partnership in 2019 is due to Sisecam Chemicals amending its postretirement benefit plan in prior years.

12. EQUITY - BASED COMPENSATION

In July 2013, our general partner established the Sisecam Resource Partners LLC 2013 Long-Term Incentive Plan (as amended to date, the “Plan” or “LTIP”). Under the LTIP as it existed at December 31, 2021, the Partnership is authorized to grant various unit based awards of our common units to employees, officers, consultants and non-employee directors. The Plan provides for

Table of Contents

awards in the form of common units, phantom units, distribution equivalent rights (“DERs”), cash awards and other unit-based awards.

All employees, officers, consultants and non-employee directors of us and our parents and subsidiaries are eligible to be selected to participate in the Plan. As of December 31, 2021, subject to further adjustment as provided in the Plan, a total of 0.6 million common units were available for awards under the Plan. Any common units tendered by a participant in payment of the tax liability with respect to an award, including common units withheld from any such award, will not be available for future awards under the Plan. Common units awarded under the Plan may be reserved or made available from our authorized and unissued common units or from common units reacquired (through open market transactions or otherwise). Any common units issued under the Plan through the assumption or substitution of outstanding grants from an acquired company will not reduce the number of common units available for awards under the Plan. If any common units subject to an award under the Plan are forfeited, any common units counted against the number of common units available for issuance pursuant to the Plan with respect to such award will again be available for awards under the Plan. The Partnership has made a policy election to recognize forfeitures as they occur in lieu of estimating future forfeiture activity under the Plan.

Non-employee Director Awards

During the year ended December 31, 2021, a total of 17,511 common units were granted and fully vested to non-employee directors, and 21,720 were granted during the year ended December 31, 2020. The grant date average fair value per unit of these awards was $13.20 and $9.88 for the years ended December 31, 2021 and 2020, respectively. The total fair value of these awards was approximately $0.2 million during the years ended December 31, 2021 and 2020, respectively.

Time Restricted Unit Awards

We grant restricted unit awards in the form of common units to certain employees which vest over a specified period of time, usually between one to three years, with vesting based on continued employment as of each applicable vesting date. Award recipients are entitled to distributions subject to the same restrictions as the underlying common unit. The awards are classified as equity awards, and are accounted for at fair value at grant date.

The CoC Transaction as discussed in Note 1, General, “Completed Change in Control Transaction,” triggered the change in control provisions associated with the time restricted unit awards, resulting in the remaining unvested time restricted unit awards becoming immediately vested as of the CoC Transaction date. As of December 31, 2021, there are no unvested time restricted unit awards and no unrecognized related compensation expense.

The following table presents a summary of activity on the Time Restricted Unit Awards for the years ended December 31, 2021 and 2020:


	2021			2020
(Units in whole numbers)	Number of Units	Grant-Date Average Fair Value per Unit (1)		Number of Units	Grant-Date Average Fair Value per Unit (1)

Forfeited	(1,332)	16.45		(5,715)	18.38
Unvested at the end of the year	—	$	—	21,937	$	17.57

Total Return Performance Unit Awards

Historically, we have granted TR Performance Unit Awards to certain employees. The TR Performance Unit Awards represent the right to receive a number of common units at a future date based on the achievement of market-based performance requirements in accordance with the TR Unit Performance Award agreement, and also include Distribution Equivalent Rights (“DERs”). DERs are the right to receive an amount equal to the accumulated cash distributions made during the period with respect to each common unit issued upon vesting. The TR Performance Unit Awards vest at the end of the performance period, usually between two to three years from the date of the grant. Performance is measured on the achievement of a specified level of total return, or TR, relative to the TR of a peer group comprised of other limited partnerships. The potential payout ranges from 0-200% of the grant target quantity and is adjusted based on our total return performance relative to the peer group. For purposes of the table below the number of units are included at target quantity.

Table of Contents

We utilized a Monte Carlo simulation model to estimate the grant date fair value of TR Performance Unit Awards granted to employees. These type of awards, with market conditions, require the input of highly subjective assumptions, including expected volatility and expected distribution yield. Historical and implied volatilities were used in estimating the fair value of these awards.

The following table presents a summary of activity on the TR Performance Unit Awards for the years ended December 31:


	2021			2020
(Units in whole numbers)	Number of Units	Grant-Date Average Fair Value per Unit (1)		Number of Units	Grant-Date Average Fair Value per Unit (1)
Unvested at the beginning of year	7,678	$	41.53	20,173	$	41.79

Vested	(7,678)	41.53		(7,654)	42.21

Forfeited	—	—		(4,841)	41.53
Unvested at the end of the year	—	$	—	7,678	$	41.53

(1) Determined by dividing the aggregate grant date fair value of awards by the number of awards issued.

2019 Performance Unit Awards

On September 23, 2019, the board of directors of our general partner approved a new form of performance unit award to be granted based upon the achievement of certain financial, operating and safety-related performance metrics (“2019 Performance Unit Awards”) pursuant to our LTIP, and the vesting of the 2019 Performance Unit Awards is linked to a weighted average consisting of internal performance metrics defined in the 2019 Performance Unit Award agreement (the “Performance Metrics”) during a three-year performance period (the “Measurement Period”). The vesting of the 2019 Performance Unit Awards, and number of common units of the Partnership distributable pursuant to such vesting, is dependent on our performance relative to a pre-established budget over the Measurement Period; provided, that the awardee remains continuously employed with our general partner or its affiliates or satisfies other service-related criteria through the end of the Measurement Period, except in certain cases of Changes in Control (as defined in our LTIP) or the awardee’s death or disability.

Vested 2019 Performance Unit Awards will be settled in our common units, with the number of such common units payable under the award to be calculated by multiplying the target number provided in the corresponding 2019 Performance Unit Award agreement by a payout multiplier, which may range from 0%-200% in each case, as determined by aggregating the corresponding weighted average assigned to the Performance Metrics. The 2019 Performance Unit Awards also contain DERs and grant the recipient the right to receive an amount equal to the accumulated cash distributions made during the period with respect to each common unit issued. Upon vesting of the 2019 Performance Unit Awards, the award recipient is entitled to receive a cash payment equal to the sum of the distribution equivalents accumulated with respect to vested 2019 Performance Unit Awards during the period beginning on January 1, 2019 and ending on the applicable vesting date. The 2019 Performance Unit Awards granted to award recipients during 2019 have a performance cycle that began on January 1, 2019 and will end on December 31, 2021. At December 31, 2021 and 2020, respectively, the Partnership's (i) unrecognized compensation expense for unvested performance based units was de minimis and; (ii) the weighted-average period over which compensation is expected to be recognized is de minimis and approximately one year.

The following table presents a summary of activity on the 2019 Performance Unit Awards for the years ended December 31, 2021 and 2020:


	Year Ended December 31, 2021			Year Ended December 31, 2020
(Units in whole numbers)	Number of Common Units	Grant-Date Average Fair Value per Unit(1)		Number of Common Units	Grant-Date Average Fair Value per Unit (1)
Unvested at the beginning of period	29,057	$	16.45	35,908	$	16.45
Forfeited	(3,995)	16.45		(6,851)	16.45
Unvested at the end of the period	25,062	$	16.45	29,057	$	16.45

(1) Determined by dividing the weighted average price per common unit on the date of grant.

14. COMMITMENTS AND CONTINGENCIES

Lease and License Commitments

The Partnership leases and licenses mineral rights from the U.S. Bureau of Land Management, the state of Wyoming, Rock Springs Royalty Company, LLC (“RSRC”) an affiliate of Occidental Petroleum Corporation (formerly an affiliate of Anadarko Petroleum Corporation), and other private parties which provide for royalties based upon production volume. The Partnership has a perpetual right of first refusal with respect to these leases and license and intends to continue renewing the leases and license as has been its practice.

The Partnership entered into a 10-year rail yard switching and maintenance agreement on December 1, 2011. Under the agreement, the rail-switching services are provided at the Partnership’s rail yard. The Partnership’s rail yard is constructed on land leased by the third party from Rock Springs Grazing Association and on land that the third party holds an easement from Sweetwater Surface LLC. The land lease is renewable every five years for a total period of thirty years, while the Sweetwater Surface LLC easement is perpetual. The Partnership has agreed with the third party for the assignment of the lease and easement to the Partnership at any time during the land lease term. An immaterial annual rental is paid under the easement and lease. On December 1, 2021, the Partnership entered into a new 10-year agreement for rail yard switching and maintenance services.

As of December 31, 2021, the total minimum contractual rental commitments under the Partnership’s various operating leases, including renewal periods is approximately $1.6 million with the amount due in any of the next five years being immaterial.

Sisecam Chemicals typically enters into operating lease contracts with various lessors for rail cars to transport product to customer locations and warehouses. Rail car leases under these contractual commitments range for periods from one to ten years. Sisecam Chemicals’ obligation related to these rail car leases are $8.4 million in 2022, $5.0 million in 2023, $3.4 million in 2024, $2.2 million in 2025, $1.6 million in 2026 and $0.5 million thereafter. Total lease expense allocated to the Partnership from Sisecam Chemicals was approximately $10.6 million, $11.3 million and $11.8 million for the years ended December 31, 2021, 2020 and 2019, respectively, and is recorded in freight costs.

Purchase Commitments

We have financial natural gas supply contracts to mitigate volatility in the price of natural gas. As of December 31, 2021, these contracts totaled approximately $24.1 million for the purchase of a portion of our natural gas requirements over approximately the next three years. The supply purchase agreements have specific commitments of $14.1 million in 2022, $4.3 million in 2023, and $5.7 million in 2024. The Partnership has a separate contract that expired in 2021 and renews annually thereafter, for the transportation of natural gas with an average minimum annual cost of approximately $4.0 million per year.

Legal and Environmental Matters

From time to time we are party to various claims and legal proceedings related to our business. Although the outcome of these proceedings cannot be predicted with certainty, management does not currently expect any such legal proceedings we may be involved in from time to time to have a material effect on our business, financial condition and results of operations. We cannot predict the nature of any future claims or proceedings, nor the ultimate size or outcome of any such claims and legal proceedings and whether any damages resulting from them will be covered by insurance.

15. AGREEMENTS AND TRANSACTIONS WITH AFFILIATES

Sisecam Chemicals was the exclusive sales agent for the Partnership and through its membership in ANSAC, through December 31, 2020, Sisecam Chemicals had responsibility for promoting and increasing the use and sale of soda ash and other refined or processed sodium products produced. Through December 31, 2020, ANSAC served as the primary international distribution channel for the Partnership and two other U.S. manufacturers of trona-based soda ash. ANSAC operated on a cooperative service-at-cost basis to its members such that typically any annual profit or loss is passed through to the members. As previously disclosed as part of its strategic initiative to gain better direct access and control of international customers and logistics and the ability to leverage the expertise of Ciner Group, the world’s largest natural soda ash producer, effective as of the end of day on December 31, 2020, Sisecam Chemicals exited ANSAC (the “ANSAC termination date”) and ANSAC has no longer been an affiliate since January 1, 2021. Through in part the Partnership’s affiliates, the Partnership has amongst other things: (i) obtained its own international customer sales arrangements for 2021, (ii) obtained third-party export port services, and (iii) chartered and executed its own international product delivery. For the year ended December 31, 2021, the total logistic services, which are included in cost of products sold, from affiliates were approximately $3.5 million.

Although ANSAC has historically been our largest customer, the impact of Sisecam Chemicals' exit from ANSAC on our net sales, net income and liquidity was limited. With a low-cost position and improved access to international customers and control over placement of its sales in the international marketplace and logistics, we have adequately replaced these net sales made under the former agreement with ANSAC. Since January 1, 2021, Sisecam Chemicals has managed the Partnership’s sales and marketing activities for exports with the ANSAC exit being complete. Sisecam Chemicals leveraged the distributor network established by the Ciner Group in 2021 and continues to evaluate the distribution network and independent third-party distribution partners to optimize our reach into each market.

Selling, general and administrative expenses also include amounts charged to the Partnership by its affiliates principally consisting of salaries, benefits, office supplies, professional fees, travel, rent and other costs of certain assets used by the Partnership. On October 23, 2015, the Partnership entered into a Services Agreement (the “Services Agreement”) with our general partner and Sisecam Chemicals. Pursuant to the Services Agreement, Sisecam Chemicals has agreed to provide the Partnership with certain corporate, selling, marketing, and general and administrative services, in return for which the Partnership has agreed to pay Sisecam Chemicals an annual management fee and reimburse Sisecam Chemicals for certain third-party costs incurred in connection with providing such services. In addition, under the limited liability company agreement governing Sisecam Wyoming, Sisecam Wyoming reimburses us for employees who operate our assets and for support provided to Sisecam Wyoming. These transactions do not necessarily represent arm's length transactions and may not represent all costs if Sisecam Wyoming operated on a standalone basis.

The total selling, general and administrative costs charged to the Partnership by affiliates were as follows:


	Years Ended December 31,
(In millions)	2021		2020		2019

Sisecam Chemicals	$	17.2	$	16.1	$	14.9
ANSAC (1)	N/A		1.4		3.5
Total selling, general and administrative expenses - affiliates	$	17.2	$	17.5	$	18.4

(1) ANSAC allocated its expenses to its members using a pro-rata calculation based on sales.

Net sales to affiliates were as follows:

The increase in due from Sisecam Chemicals from December 31, 2020 to December 31, 2021 is due to timing of funding of pension and postretirement plans offered and administered by Sisecam Chemicals.

16. MAJOR CUSTOMERS AND SEGMENT REPORTING

Our operations are similar in geography, nature of products we provide, and type of customers we serve. As the Partnership earns substantially all of its revenues through the sale of soda ash mined at a single location, we have concluded that we have one operating segment for reporting purposes.

The net sales by geographic area consisted of the following:


	Years Ended December 31,
(In millions)	2021		2020		2019
Domestic	$	276.8	$	208.8	$	207.0

17. FAIR VALUE MEASUREMENTS

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

Derivative Financial Instruments

We have interest rate swap contracts, designated as cash flow hedges, to mitigate our exposure to possible increases in interest rates. The swap contracts consist of three individual $12.5 million swaps with an aggregate notional value of $37.5 million at both December 31, 2021 and December 31, 2020. The swaps outstanding at December 31, 2021 have various maturities through 2024.

We enter into natural gas financial forward contracts, designated as cash flow hedges, to mitigate volatility in the price of natural gas related to a portion of the natural gas we consume. These contracts generally have various maturities through 2024. These contracts had an aggregate notional value of $24.1 million and $25.9 million at December 31, 2021 and December 31, 2020, respectively.

The following table presents the fair value of derivative assets and liability derivatives and the respective locations on our consolidated balance sheets as of December 31, 2021 and December 31, 2020:

Financial Assets and Liabilities not Measured at Fair Value

The carrying value of the Sisecam Wyoming Credit Facility materially reflects the fair value as the rate is variable and its key terms are similar to indebtedness with similar amounts, durations and credit risks. The carrying value of the borrowings under the Sisecam Wyoming Equipment Financing Arrangements materially reflects the fair value as its key terms are similar to indebtedness with similar amounts, durations and credit risks that are currently available to the Partnership. See Note 9, “Debt,” for additional information on our debt arrangements.

Item 9A. Controls and Procedures

Management’s Annual Report on Internal Control over Financial Reporting

The Partnership’s management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act. Our internal control system is designed under the supervision of the Partnership’s principal executive officer and principal financial officer to provide reasonable assurance to the Partnership’s management and our general partner’s Board of Directors regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Our management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2021. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in its 2013 Internal Control—Integrated Framework. Based on this assessment, our management has concluded that as of December 31, 2021 our internal control over financial reporting is effective.

Evaluation of Disclosure Controls and Procedures

Based on an evaluation under the supervision and with the participation of the Partnership’s management, the Partnership’s principal executive officer and principal financial officer have concluded that the Partnership’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act were effective as of December 31, 2021 to ensure that information required to be disclosed by the Partnership in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms and (ii) accumulated and communicated to the Partnership’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have not been changes in the Partnership’s internal control over financial reporting during the fourth quarter of fiscal year December 31, 2021, which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Partners of

Sisecam Resources LP

Atlanta, Georgia

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Sisecam Resources LP (a majority-owned subsidiary of Sisecam Chemicals Wyoming LLC) and its subsidiary (the “Partnership”) as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2021, of the Partnership and our report dated March 14, 2022, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Partnership’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Partnership’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Item 10. Directors, Executive Officers and Corporate Governance

Our general partner manages our operations and activities on our behalf through its directors and officers. SCW LLC, which is indirectly 60% owned by Sisecam USA and 40% owned by Ciner Enterprises, owns all of the membership interests in our general partner and has the right to appoint the entire board of directors of our general partner, including our independent directors, subject to the terms of the Sisecam Chemicals Operating Agreement, which requires the directors of our general partner shall consist of six designees from Sisecam USA, two designees from Ciner Enterprises and three independent directors for so long as our general partner is legally required to appoint independent directors. Our unitholders are not entitled to elect the directors of our general partner’s board of directors or to directly or indirectly participate in our management or operations. In addition, our general partner owes certain duties to our unitholders as well as a fiduciary duty to its owners. References to “our directors” or “our executive officers” refer to the directors or executive officers of our general partner.

The Board of Directors of Our General Partner

The board of directors of our general partner (the “Board”) oversees our operations. The Board’s directors hold office until their successors have been elected or qualified or until the earlier of their death, resignation, removal or disqualification. Executive officers serve at the discretion of the Board. There are no family relationships among any of our directors or executive officers. The Board held seven meetings during the fiscal year ended December 31, 2021.

Our common units are traded on the NYSE. The NYSE does not require publicly traded partnerships listed on its exchange, such as ours, to have, and we do not intend to have, a majority of independent directors on the Board or to establish a compensation committee or a nominating and corporate governance committee.

At the date of this Report, the Board consists of the following members: Oðuz Erkan, Huseyin Kuscu, Mustafa Gorkem Elverici, Tahsin Burhan Ergene, Abdullah Kilinc, Michael E. Ducey, Thomas W. Jasper, Alec G. Dreyer, Gokhan Guralp, Hande Eroz, and Selma Oner. The Board has determined that each of Michael E. Ducey, Thomas W. Jasper and Alec G. Dreyer qualifies as an independent director under applicable SEC rules and regulations and the rules of the NYSE. Under the NYSE's listing standards, a director will not be deemed independent unless the Board affirmatively determines that the director has no material relationship with us. Based upon information requested from and provided by each director concerning his or her background, diversity, personal characteristics, business experience and affiliations, including commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships, the Board has determined that each of its independent directors has no material relationship with Sisecam Chemicals, Ciner Enterprises, Sisecam USA or us, either directly or as a partner, stockholder or officer of an organization that has a relationship with us, and is therefore independent under the NYSE's listing standards and applicable SEC rules and regulations.

Director Experience and Qualifications

In identifying and evaluating candidates as possible director-nominees of our general partner, Sisecam Chemicals and its members will assess the experience and personal characteristics of the possible nominee against the following individual qualifications, which such parties may modify from time to time:

Committees of the Board of Directors

The Board has established an audit committee and a conflicts committee. Michael E. Ducey, Thomas W. Jasper and Alec G. Dreyer are the members of the audit committee, and Thomas W. Jasper serves as chairperson. Michael E. Ducey, Thomas W. Jasper and Alec G. Dreyer are the members of our conflicts committee; and Thomas W. Jasper serves as the chairman. The Board will determine whether to refer a matter to the conflicts committee on a case-by-case basis in accordance with our partnership agreement. We do not have a compensation committee, but rather the Board approves equity grants to and compensation of our directors, and Sisecam Chemicals approves compensation of our officers subject to our review and approval under the Services Agreement.

Audit Committee

We are required to have an audit committee of at least three members who meet the independence and experience standards established by the NYSE and the Exchange Act. In accordance with the rules of the NYSE, we have appointed three independent directors of the audit committee. The Board has determined that each director appointed to the audit committee is “financially literate,” and Michael E. Ducey and Alec G. Dreyer, who are members of the audit committee, and Thomas W. Jasper, who serves as chairperson of the audit committee, each has “accounting or related financial management expertise” and constitutes an “audit committee financial expert” in accordance with SEC and NYSE rules and regulations. The audit committee operates pursuant to a written charter, an electronic copy of which is available on our website at www.ciner.us.com under the Investor Overview - Governance Documents tab.

The audit committee assists the Board in its oversight of the integrity of our financial statements and our compliance with legal and regulatory requirements and partnership policies and controls. The audit committee operates under a written charter and has been given the sole authority to (1) retain and terminate our independent registered public accounting firm, (2) approve all auditing services and related fees and the terms thereof performed by our independent registered public accounting firm, (3) establish policies and procedures for pre-approval of all audit, non-audit and internal control related services to be rendered by our independent registered public accounting firm and (4) review and evaluate all related party transactions or dealings with parties related to us and disclosures of such transactions or dealings in our annual report on Form 10-K. The audit committee is also responsible for confirming the independence and objectivity of our independent registered public accounting firm. Our independent registered public accounting firm has been given unrestricted access to the audit committee and our management, as necessary. The audit committee met eight times during the fiscal year ended December 31, 2021.

Conflicts Committee

The conflicts committee reviews specific matters that may involve conflicts of interest between our general partner or any of its affiliates, on the one hand, and us, our partners and any of our subsidiaries, on the other hand, in accordance with the terms of our partnership agreement. The conflicts committee operates pursuant to a written charter, an electronic copy of which is available on our website at www.ciner.us.com under the Investor Overview - Governance Documents tab. The members of the conflicts committee may not be officers or employees of our general partner or directors, officers or employees of its affiliates, including SCW LLC; may not hold an ownership interest in our general partner or its affiliates other than common units or awards under any long-term incentive plan, equity compensation plan or similar plan implemented by our general partner or the partnership; and must meet the independence standards established by the NYSE and the Exchange Act to serve on an audit committee of a board of directors. Any matters approved by the conflicts committee will be conclusively deemed to be in our best interest, approved by all of our partners and not a breach by our general partner of any duties it may owe us or our unitholders. Any unitholder challenging any matter approved by the conflicts committee will have the burden of proving that the members of the conflicts committee did not believe that the matter was in the best interests of our partnership. Moreover, any acts taken or omitted to be taken in reliance upon the advice or opinions of experts such as legal counsel, accountants, appraisers, management consultants and investment bankers, where our general partner (or any members of the Board including

112

Table of Contents

any member of the conflicts committee) reasonably believes the advice or opinion to be within such person's professional or expert competence, shall be conclusively presumed to have been done or omitted in good faith. The conflicts committee did not meet in 2021.

Board Leadership Structure and Role in Risk Oversight

The Board does not mandate the separation of the offices of chairperson of the Board and chief executive officer. Instead, that relationship is defined and governed by the first amended and restated limited liability company agreement, as amended, of our general partner, which permits the same person to hold both offices. The Board believes that whether the offices of Chairperson of the Board and Chief Executive Officer are combined or separated should be decided by the Board, from time to time, in its business judgment after considering relevant circumstances. On February 11, 2022, Mr. Erkan resigned as Chairperson of the Board and effective as of the same date, Mr. Mustafa Görkem Elverici was appointed as the new Chairperson of the Board to serve until the earlier of his removal, his death or resignation. Directors of the Board are designated or elected in accordance with the terms of the limited liability company agreement of our general partner and the Sisecam Chemicals Operating Agreement. Pursuant to such arrangements, the Board shall consist of six designees from Sisecam USA, two designees from Ciner Enterprises and three independent directors for as long as our general partner is legally required to appoint such independent directors. Accordingly, unlike holders of common stock in a corporation, our unitholders have only limited voting rights on matters affecting our business or governance, subject in all cases to any specific unitholder rights contained in our partnership agreement.

Our corporate governance guidelines provide that the Board is responsible for reviewing the process for assessing the major risks facing us and the options for their mitigation. This responsibility is largely satisfied by our audit committee, which is responsible for reviewing and discussing with management and our independent registered public accounting firm our major risk exposures and the policies management has implemented to monitor such exposures, including our financial risk exposures and risk management policies.

Executive Sessions of Independent Directors and Lead Independent Director

Effective on February 10, 2017, the Board appointed Michael E. Ducey as the Board’s Lead Independent Director. Under our Corporate Governance Guidelines, the Lead Independent Director is responsible for:

•presiding at executive sessions of the independent directors of the Board;

•working with the committee chairs to set agendas and lead the discussion of regular meetings of the directors outside the presence of management;

•providing feedback regarding these meetings to the Chairperson of the Board; and

•otherwise serves as a liaison between the independent directors and the Chairperson of the Board.

The Board holds regular executive sessions in which the independent directors of the Board meet without any members of management present. The purpose of these executive sessions is to promote open and candid discussion among the independent directors. Pursuant to our Corporate Governance Guidelines, we have our Lead Independent Director preside over these executive sessions.

Communication with the Board of Directors

A holder of our units or other interested party who wishes to communicate with the non-management directors or independent directors of our general partner may do so by contacting our corporate secretary at the address or phone number appearing on the front page of this Report. Communications will be relayed to the intended recipient of the Board except in instances where it is deemed unnecessary or inappropriate to do so. Any communications withheld will nonetheless be recorded and available for any director who wishes to review them.

Delinquent Section 16(a) Reports

To our knowledge, based solely on a review of our the reports filed with the SEC and the written representations of our directors and executive officers, we believe that all reporting requirements for fiscal year 2021 were complied with by each person who at any time during the 2021 fiscal year was a director or an executive officer or held more than 10% of our common stock, except for the following: Mr. Kuscu filed a Form 3 on January 13, 2022; Mr. Elverici filed a Form 3 on January 14, 2022; Mr. Ergene filed a Form 3 on January 14, 2022; Mr. Kilinc filed a Form 3 on January 14, 2022; Mr. Guralp filed a Form 3 on January 14, 2022; Ms. Eroz filed a Form 3 on January 14, 2022; and Ms. Oner filed a Form 3 on January 14, 2022.

ITEM 11. Executive Compensation

Background

This “Compensation Discussion and Analysis” or “CD&A” sets forth an overview of the philosophy, objectives and elements of the executive compensation program for executives who perform services on our behalf and the key executive compensation decisions that were made by us or Sisecam Chemicals Resources LLC (formerly known as Ciner Resources Corporation and OCI Chemical Corporation) for 2021. This CD&A provides context and background for the compensation earned by and awarded to our general partners’ named executive officers (“NEOs”), as reflected in the compensation tables contained in the CD&A.

For 2021, our general partners’ NEOs were as follows:

Individuals Serving as Named Executive Officers as of December 31, 2021:

•Ahmet Tohma, Chief Financial Officer

•Christopher L. DeBerry, Chief Accounting Officer and Corporate Controller

On February 11, 2022, the Partnership disclosed that Turkiye Sise ve Cam Fabrikalari A.S. of Istanbul, Turkey (“Sisecam”), announced its intention (i) to appoint Mr. Ertugrul Kaloglu as President and Chief Executive Officer of Sisecam Chemicals and its subsidiaries, including our general partner, effective upon the receipt of all requisite U.S. immigration and corporate approvals (the “Kaloglu Effective Date”), and (ii) to appoint Mr. Mehmet Nedim Kulaksizoglu as Chief Financial Officer of Sisecam Chemicals and its subsidiaries, including our general partner, effective upon the receipt of all requisite U.S. immigration and corporate approvals (the “Kulaksizoglu Effective Date”). Mr. Oguz Erkan has agreed to resign as the President and Chief Executive Officer of the general partner as of the Kaloglu Effective Date in order to pursue other opportunities with the Ciner Group. After the effectiveness of the foregoing resignation Mr. Erkan is expected to remain as a member of the board of directors of the general partner and continue to serve as President and Chief Executive Officer of Ciner Enterprises. Mr. Ahmet Tohma has agreed to resign as the Chief Financial Officer of the general partner as of the Kulaksizoglu Effective Date in order to pursue other opportunities with the Ciner Group and is expected to continue to serve as the WE Soda Group’s Chief Financial Officer.

Mr. Freydel resigned as Vice President, Supply Chain and Finance of our general partner and as director and various officer roles within members of the Ciner Group, each effective as of July 27, 2021.

Executive Summary

We are managed by our general partner and neither we nor our general partner directly employs any of the persons responsible for managing our business. Instead, the executive officers of our general partner are employees of Sisecam Chemicals. Other than awards that may be granted by our Board under our general partner’s 2013 Long-Term Incentive Plan (as amended to date, the “Plan”), it is Sisecam Chemicals that has ultimate-decision making authority to determine and approve the compensation program and individual compensation of the employees who perform services on our behalf, including the NEOs. Sisecam Chemicals indirectly owns and controls our general partner and indirectly owns approximately 72% of the outstanding limited partner interests in us and all of our incentive distribution rights. We reimburse Sisecam Chemicals for such services and compensation, and our reimbursement is governed by the Services Agreement, dated as of October 23, 2015 (the “Services Agreement”), by and among us, our general partner and Sisecam Chemicals, under which we have agreed to pay

114

Table of Contents

Sisecam Chemicals an annual management fee, subject to quarterly adjustments, with estimates of such proposed annual fees and costs subject to initial review and approval by our Board. The annual management fee proposed by Sisecam Chemicals is determined based on the estimated time the employees are expected to spend on our business, and the costs for such employees, including the NEOs, are determined based on Sisecam Chemicals’ compensation policies and practices. Each of the NEOs devoted a majority of their time to our business for the year ended December 31, 2021.

Neither we nor our general partner maintains any employee benefit plans or arrangements, or any defined benefit pension plans, nonqualified deferred compensation plans or retirement plans. Rather, the NEOs are eligible to participate under the same plans that Sisecam Chemicals offers to similarly situated employees and we reimburse Sisecam Chemicals for amounts allocated to the NEOs under such plans to the extent such expenses are allocated to the Partnership under the Services Agreement.

Determination of Compensation Decisions

Other than awards that may be granted under the Plan, Sisecam Chemicals determines and sets the compensation of the employees that perform services on our behalf, including the NEOs, and, as a result, retains ultimate decision-making authority as to the compensation philosophy for its employees, including the NEOs. We reimburse Sisecam Chemicals for such services and compensation, and our reimbursement is governed by the Services Agreement, under which we have agreed to pay Sisecam Chemicals an annual management fee, subject to quarterly adjustments, with estimates of such proposed annual fees and costs subject to initial review and approval by our Board. The annual management fee proposed by Sisecam Chemicals is determined based on the estimated time the employees, including the NEOs, are expected to spend on our business, and the costs for such employees, including the NEOs, are determined based on Sisecam Chemicals’ compensation policies and practices. We have no control over and do not direct or establish Sisecam Chemicals’ executive compensation policies and practices, but instead our Board annually reviews the estimated annual management fee proposed by Sisecam Chemicals and reviews any quarterly adjustments made by Sisecam Chemicals to such fee.

Because neither we nor our general partner directly employ any of the NEOs and because Sisecam Chemicals has ultimate decision-making authority as to the compensation for the NEOs to manage our business and affairs, we did not provide traditional fixed or discretionary compensation (e.g., salary or bonus) to the NEOs in 2021. Rather, we reimburse Sisecam Chemicals for those amounts and other benefits provided by Sisecam Chemicals or its affiliates or related parties to the NEOs that are allocated to us and subject to reimbursement under our Services Agreement. At the same time, we believe that the NEOs should have an ongoing stake in our success, that their interests should be aligned with those of our unitholders and that the best interests of our unitholders may be further advanced by enabling the NEOs who are responsible for our management, growth and success, to receive compensation in the form of long-term incentive awards. Accordingly, our Board periodically grants long-term incentives in the form of awards under the Plan, which was adopted in connection with our initial public offering and is administered by our Board. The Plan provides for awards in the form of common units, phantom units, distribution equivalent rights, cash awards and other unit-based awards. All awards granted under the Plan are approved by our Board. All employees, officers, consultants and non-employee directors of us and our parents and subsidiaries are eligible to be selected to participate in the Plan.

Our Board’s decisions with respect to the amount of awards made under the Plan to the NEOs are governed by the following objectives:

•to motivate and retain our general partner’s key executives;

•to align the long-term economic interests of our general partner’s executives with those of our unitholders; and

•to reward excellence and performance by our general partner’s executives that increase the value of our units.

Our Board believes that mix of base salary, incentive cash awards and other employment benefit plan or arrangements determined by Sisecam Chemicals and allocated to us under the Services Agreement and equity-based awards granted by our Board under the Plan fit the Partnership’s overall compensation objectives. Our Board believes this mix of compensation provides competitive compensation opportunities to align and drive employee performance in support of the Partnership’s business strategies, as well as Sisecam Chemicals’, and to attract, motivate and retain high-quality talent with the skills and competencies required by the Partnership and Sisecam Chemicals.

Elements of Compensation

Overview

Sisecam Chemicals provides compensation to its executives in the form of (i) base salaries, (ii) annual performance-based cash incentive awards under an incentive compensation plan of Sisecam Chemicals (the “Short-Term Bonus”) that provides cash incentive compensation to its executive employees and salaried employees tied to our annual EBITDA and

115

Table of Contents

controllable costs, and (iii) participation in various other employment plans and arrangements, including (1) medical, dental, vision, disability and life insurance plans for its employees, (2) a 401(k) retirement plan (the “401(k) Plan”), which permits employees to contribute specified percentages of their compensation, (3) a post-retirement benefit plan (“Post-Retirement Plan”), which enables its employees to obtain postretirement benefits, other than pensions, accounted for on an accrual basis over an employee’s period of service, if such employees reach retirement age while still employed, and (4) deferred-compensation plans (“Deferred Compensation Plans”), which allow a select group of management employees to defer compensation to a future date. Other than our Board’s review of the management fee under the Services Agreement, all determinations with respect to such benefits are made by Sisecam Chemicals, or the plans, as the case may be, without input from us, our general partner or our Board, and we only bear the cost of such program or benefits that are charged back to us pursuant to the Services Agreement.

In addition to such aforementioned compensation, our Board has historically granted long-term equity awards under the Plan to the NEOs from time to time, which to date have consisted of restricted unit awards and performance-based awards that are described further below. Our Board has not adopted any formal or informal policies or guidelines for allocating compensation between long-term and current compensation, between cash and non-cash compensation or among different forms of compensation other than its belief that in addition to reimbursement of the annual management fee under the Services Agreement, equity-based compensation should be made to the NEOs for the reasons set forth above. The decision to grant awards under the Plan by our Board is strictly made on a subjective and individual basis after consideration of the relevant factors discussed herein.

The NEOs are not subject to any agreements or arrangements with us or our general partner pursuant to which they would receive any payments or benefits in connection with a termination of their employment or a change in control of us or our general partner, other than with respect to our current restricted unit awards and performance-based unit awards granted to the NEOs under the Plan which contain provisions that could accelerate vesting of the award in certain situations. In addition, we could be required to reimburse Sisecam Chemicals for amounts awarded to the NEOs and allocated to us under the Short-Term Bonus in connection with an NEO’s termination of employment or a change in control of us or our general partner.

Base Salary.

As discussed above, we reimburse Sisecam Chemicals for an annual management fee under our Services Agreement. Base salaries allocated to the NEOs under the Services Agreement are generally designed by Sisecam Chemicals to provide competitive fixed rates of pay recognizing employees’ different levels of responsibility and performance. In setting base salaries for its officers, Sisecam Chemicals considers factors including, but not limited to, the scope of the officer’s responsibilities, individual contribution, experience and sustained performance, general economic conditions, industry specific business conditions, base salaries for comparable positions in similar industries, the tenure of the officers and base salaries of the officers relative to one another. Adjustments are made generally by Sisecam Chemicals in accordance with the considerations described above and to maintain base salaries at competitive levels. The annual management fee proposed by Sisecam Chemicals is determined based on the estimated time such employees are expected to spend on our business and the compensation principles set forth above.

The allocable portion of the base salaries paid to the NEOs during the fiscal year ended December 31, 2021 are set forth in the table below and in the “Salary” column of the “Summary Compensation Table”:


Named Executive Officer						2021 Total Base Salary Allocable to Us (%)
Oğuz Erkan						88%
Ahmet Tohma						88%
Christopher L. DeBerry						82%
Raymond Katekovich						99%
Marla Nicholson						95%
Eduard Freydel (1)						85%

(1) Mr. Freydel resigned as Vice President Supply Chain and Finance of our general partner effective July 27, 2021.

Cash Incentive Awards.

In addition to reimbursing Sisecam Chemicals under the Services Agreement for allocable portions of the base salaries of the NEOs, we also reimburse Sisecam Chemicals for the amounts of annual cash incentive awards provided to the NEOs under the Short-Term Bonus that are allocated to the Partnership. The percentage of each NEO’s annual cash incentive award that is allocated to the Partnership is equal to the portion of the NEO’s base salary that is allocated to the Partnership as set forth

116

Table of Contents

above. Annual cash incentive awards are used by Sisecam Chemicals to motivate and reward its executives and employees for the achievement of objectives aligned with value creation and/or to recognize individual contributions to our performance. The amount of any annual cash incentive payment to the NEOs are generally set by Sisecam Chemicals using a target bonus amount equal to a percentage of each NEO’s annual base salary. Sisecam Chemicals then determines the actual amount of such annual cash incentive payment to the NEOs based upon the Partnership’s actual performance and such NEO’s individual performance. Other than our periodic review of the amount reimbursable under our Services Agreement, such annual incentive bonuses are determined on a discretionary basis solely by Sisecam Chemicals without input from us, our general partner or our Board. Unless otherwise determined, payments under the Short-Term Bonus have historically been subject to an individual’s continued employment through the end of the applicable calendar year.

For 2021, annual cash incentive bonuses were targeted at the percentage of each NEO’s annual base salary as shown below:


Named Executive Officer						2021 Target Bonus as a Percent of Base Salary
Oğuz Erkan						55%
Ahmet Tohma						—%
Christopher L. DeBerry						30%
Raymond Katekovich						30%
Marla Nicholson						50%
Eduard Freydel (1)						30%

(1) Mr. Freydel resigned as Vice President Supply Chain and Finance of our general partner effective July 27, 2021.

For 2021, each NEO was eligible to receive an annual cash incentive bonus based on achievement of pre-established targets for EBITDA, tons produced, and controllable costs for the Partnership of approximately $85.9 million and 2.8 tons, and $110.4 million, respectively. For the purpose of calculation under the Short-Term Bonus, EBITDA was defined as earnings before interest, taxes, depreciation and amortization. Under the Short-Term Bonus, bonus payments are based 60% on meeting or exceeding target EBITDA, 20% on meeting or exceeding tons produced target, and 20% on meeting or exceeding controllable costs target as well as individual performance in connection with achievement of such targets. An individual performance multiplier ranging from 0x to 1.25x is applied based on the NEOs 2021 performance rating. There are generally no payouts for results below 75% of the EBITDA target. The maximum payout multiplier is capped at 2.0x.

EBITDA, tons produced and controllable costs used by Sisecam Chemicals for each NEOs’ bonus calculation for the year ended December 31, 2021 was: $88.7 (“2021 EBITDA”), 2.7 million (“2021 tons produced”) and $104.7 (“2021 Controllable Costs”), respectively. In accordance with the Change in Control language, no individual performance multipliers were applied for 2021. Based on 2021 EBITDA, 2021 tons produced, and 2021 controllable costs achieved by the Partnership, Messrs. Erkan, DeBerry, Katekovich and Ms. Nicholson earned annual incentive bonuses allocable to us equal to $341,190, $114,905, $132,990 and $222,588, respectively, representing 64%, 35%, 35% and 59% of their annual 2021 base salary.

Long-Term Equity Incentive Awards.

In addition to the salaries and cash incentive awards paid by Sisecam Chemicals to the NEOs and reimbursable by us under the Services Agreement, our Board administers the Plan and approves awards granted under the Plan to the NEOs. The Plan is intended to provide incentives that will attract, motivate and retain valued employees, offering them a greater stake in our success and a closer identity with us in order to better align them with the long-term interests of our unitholders, and to reward excellence and performance that increases the value of our units. The Plan provides for awards in the form of common units, phantom units, distribution equivalent rights, cash awards and other unit-based awards.

As of December 31, 2021, and subject to adjustments as provided in the Plan, there were a total of 643,117 common units available for issuance under the Plan. Any common units tendered by a participant in payment of the tax liability with respect to an award, including common units withheld from any such award, will not be available for future awards under the Plan. Common units awarded under the Plan may be reserved or made available from our authorized and unissued common units or from common units reacquired (through open market transactions or otherwise). Any common units issued under the Plan through the assumption or substitution of outstanding grants from an acquired company will not reduce the number of common units available for awards under the Plan. If any common units subject to an award under the Plan are forfeited, any common units counted against the number of common units available for issuance pursuant to the Plan with respect to such award will again be available for awards under the Plan. To date, awards under the Plan that have been granted to the NEOs include (i) time-based vesting conditions (“restricted unit awards”), (ii) performance-based vesting conditions linked to the relative performance of the Partnership’s common units during a pre-determined performance period (“TR performance-based

117

Table of Contents

unit awards”) and (iii) performance-based vesting conditions linked to the achievement of certain financial, operating and safety-related performance metrics (“2019 performance-based unit awards”).

The restricted unit awards provide the NEOs with the rights of a unitholder in the Partnership with respect to a restricted unit, except cash distributions paid by the Partnership with respect to such a restricted unit will be credited to a separate account for such restricted unit and, subject to any tax withholding considerations, will be paid to the recipient at the time such restricted unit vests. The outstanding restricted unit awards granted to the NEOs have vested in substantially equal one-third increments so that any restricted unit award (and any related restricted cash distribution) will be 100% vested three years from the grant date, so long as the award recipient remains continuously employed by the Partnership Entities (as defined in the corresponding restricted unit award agreement) from the date of grant through each applicable vesting date, unless otherwise vesting earlier pursuant to the terms of the restricted unit award with regard to “Change in Control” (as defined in the Plan), death or disability. If an award recipient’s service with the Partnership Entities or membership on the Board, as applicable, is terminated prior to full vesting of the restricted units, then the award recipient will forfeit all unvested restricted units and related restricted cash distributions, except that upon a “Change in Control” or termination of the participant due to death or disability all unvested restricted units and related restricted cash distributions will become immediately vested in full.

The vesting of the outstanding TR performance-based unit awards, and number of common units of the Partnership distributable pursuant to such vesting, is dependent on the relative performance of the Partnership’s common units compared to an initial peer group consisting of other publicly traded partnerships (provided that the participant remains continuously employed with our general partner or its affiliates or satisfies other service-related criteria through the end of the performance period and certification of the results, except in certain cases of “Change in Control” or the participant’s death or disability). Vested TR performance-based unit awards are to be settled in the Partnership’s common units, with the number of such units payable under the award to be calculated by multiplying the target number provided in the TR performance-based unit award agreement by a performance percentage, which may range from 0% to 200%, depending on the relative performance of the Partnership’s common units over the performance period compared to common units of each member of the peer group. In addition, upon vesting of the TR performance-based unit award, the award recipient is entitled to receive a cash payment equal to the distribution equivalents accumulated with respect to the target number provided in the TR performance-based unit award agreement, multiplied by the performance percentage described in the immediately preceding sentence. The typical performance cycle has been a three-year period.

Effective July 27, 2021, Mr. Freydel resigned as Vice President Supply Chain and Finance of our general partner, and all of his restricted unit awards and TR performance-based unit awards and related cash distributions paid thereon that had not vested prior to July 27, 2021 were forfeited.

In 2021, (i) Mr. DeBerry, Mr. Freydel, and Mr. Katekovichhad had 423 restricted units, 403 restricted units, and 888 restricted units, respectively, vest on March 15, 2021, which in each case were originally granted on April 26, 2018, (ii) Mr. DeBerry, Mr. Erkan, Mr. Freydel, Mr. Katekovich and Ms. Nicholson had 1,281 restricted units, 3,284 restricted units, 1,332 restricted units, 1,815 restricted units and 463 restricted units respectively, vest on March 15, 2021, which in each case were originally granted on September 23, 2019, (iii) Mr. DeBerry, Mr. Erkan, Mr. Katekovich and Ms. Nicholson had 1,281 restricted units, 3,284 restricted units, 1,815 restricted units and 463 restricted units respectively, vest on December 21, 2021, which in each case were originally granted on September 23, 2019, and (iv) Mr. DeBerry, Mr. Freydel and Mr. Katekovich had 1,192 TR performance units, 1,135 TR performance, and 2,505 TR performance units, respectively, vest on January 21, 2021, which were originally granted on April 26, 2018.

Severance and Change in Control Arrangements

The NEOs are not parties to any agreements or arrangements with us or our general partner pursuant to which they would receive any payments or benefits in connection with a termination of their employment or a change in control of us or our general partner, except that our current restricted unit awards, TR performance-based unit awards and 2019 performance-based unit awards under the Plan contain provisions that could accelerate vesting of the award in certain situations. In the event that one of the NEOs is terminated by us or one of our affiliates prior to the vesting date of the restricted unit awards, TR performance-based unit awards or 2019 performance-based unit awards, all such restricted units, TR performance-based unit awards and 2019 performance-based unit awards will immediately be forfeited without consideration unless such termination is due to the NEO’s death or disability.

For the restricted unit awards and related cash distributions accumulated thereunder, in the event of the NEO’s death or disability, or if a “Change in Control” occurs, all restricted unit awards will become 100% vested. For the TR performance-based unit awards and the 2019 performance-based unit awards and the related cash distributions accumulated thereunder, respectively, the awards granted to the NEOs are earned and vested and/or forfeited, as the case may be, in the amounts described in further detail in the section titled “Potential Payments upon Termination or Change-in-Control” as described below.

118

Table of Contents

The Plan generally defines a “Change in Control” as occurring on one or more of the following events:

(a) the acquisition in one or more transactions by any “person” (as such term is used for purposes of Section 13(d) or Section 14(d) of the Exchange Act) but excluding, for this purpose, (i) the Partnership or any of our parents or their subsidiaries or (ii) any employee benefit plan of any entity described in clause (i) above (the entities described in clauses (i) and (ii) hereof, “Excluded Persons”), of more than fifty percent (50%) of the combined voting power of the Partnership’s or our general partner’s then outstanding voting securities;

(b) the consummation of a merger or consolidation involving the Partnership or our general partner if the owners of the Partnership or our general partner (as applicable), immediately before such merger or consolidation, do not own, directly or indirectly, immediately following such merger or consolidation, at least fifty percent (50%) of the combined voting power of the outstanding voting securities of the entity resulting from such merger or consolidation; or

(c) the acquisition by any “person” (as such term is used for purposes of Section 13(d) or Section 14(d) of the Exchange Act), other than an Excluded Person, in a single transaction or in a series of related transactions occurring during any period of 12 consecutive months, of assets from the Partnership or our general partner that have a total gross fair market value equal to or more than 51% of the total gross fair market value of all of the assets of the Partnership or our general partner (as applicable) and its subsidiaries (determined on a consolidated basis) immediately prior to such acquisition or acquisitions.

The Short-Term Bonus provided by Sisecam Chemicals also contains provisions that could accelerate vesting of the payment in certain situations. For the Short-Term Bonus, if a “change in control” occurs, those individuals associated with the business that is sold will be paid their pro-rata portion of the applicable incentive award. To be eligible, a participant must be an active employee as of the date of the change in control. The pro-rata calculation will use the participant’s annual base salary in effect as of the date of the change in control and actual business results through the change in control. The financial goals and the individual participation percentage will be pro-rated through the date of the change in control and no individual performance multiplier will apply.

The Short-Term Bonus generally describes a “change in control” as occurring in the event that Sisecam Chemicals completes a direct or indirect sale to an unrelated third party of all or substantially all of the equity interests or assets in one of the businesses covered by the Short-Term Bonus.

Other Elements of Compensation and Perquisites

Neither we nor our general partner sponsor any employee benefit plans or arrangements, any defined benefit pension plan or nonqualified deferred compensation plans or any retirement plans for the NEOs, and neither we nor our general partner provide the NEOs with any perquisites. Instead, these types of benefits are provided in certain situations to the NEOs in connection with their employment by Sisecam Chemicals and are governed in all cases by the terms of the applicable plan documents. The NEOs have been eligible to participate under the same plans that Sisecam Chemicals offers to its other employees with respect to medical, dental, vision, disability and life insurance plans, and the NEOs have participated in the Short-Term Bonus, the 401(k) Plan and the Post-Retirement Plan. The NEOs participate in these plans on the same basic terms as all other similarly situated employees. The NEOs also participate in Deferred Compensation Plans and receive certain perquisites provided by Sisecam Chemicals. For the year ended December 31, 2021, perquisites included a company car for Mr. Erkan and Mr. Tohma and a country club membership for Mr. Katekovich. All determinations with respect to such benefits are made by Sisecam Chemicals, or the plans, as the case may be, without input from us or our general partner or our Board, and we only bear the cost of such program or benefits that are charged back to us under the provisions of the Services Agreement.

Compensation Committee Interlocks and Insider Participation

As a limited partnership, we are not required by the New York Stock Exchange (“NYSE”) to establish a compensation committee. As discussed above, we do not directly employ any of the NEOs and, outside of the Plan, all compensation granted to the NEOs is under Sisecam Chemicals’ ultimate direction and control. Mr. Erkan, our general partner’s Chief Executive Officer, has participated in his capacity as a director of our general partner in the deliberations of our Board concerning previous grants under the Plan and made recommendations to our Board regarding NEO compensation provided under the Plan in 2021. Our Board does not currently intend to establish a compensation committee.

Compensation Consultants

Our Board did not retain a compensation consultant in 2021.

Unit Ownership Requirements

119

Table of Contents

Neither we nor our general partner has established unit ownership requirements for the NEOs, provided that, in order to more closely align the interests of non-management directors of our general partner and unitholders in us, we and our general partner have equity ownership guidelines that require non-management directors of our general partner to hold common units in the Partnership within five years from their initial election date to our board that have an aggregate value equivalent to three times the annual cash retainer provided by our board to such director.

Guidelines for Trading by Insiders

We and our general partner maintain policies that govern trading in our common units by the officers and directors of our general partner who are required to report under Section 16 of the Exchange Act, as well as certain other employees who may have regular access to material non-public information about us. These policies include pre-approval requirements for all trades in our common units and periodic trading “black-out” periods designed with reference to our quarterly financial reporting schedule. These policies also prohibit such persons from short selling, purchasing our common units on margin or pledging our common units.

Compensation Risk Assessment

Based on an internal review by our Board of the Plan, the Services Agreement and its understanding of the material compensation programs of Sisecam Chemicals, our general partner has concluded that there are no plans that provide meaningful incentives for employees, including the NEOs, to take risks that would be reasonably likely to have a material adverse effect on the Partnership.

CEO Pay Ratio

Neither we nor our general partner have any employees. As a result, we have no basis for disclosing the annual compensation and corresponding ratio as required under Item 402(u) of Regulation S-K.

Compensation Committee Report

Our Board has reviewed and discussed with management the compensation discussion and analysis contained in this Report as required by Item 402(b) of Regulation S-K. Based on such review and discussion, our Board has recommended that this Compensation Discussion and Analysis be included in the annual report on Form 10-K for the year ended December 31, 2021.

Summary Compensation Table

The following table summarizes the compensation paid to the NEOs and allocated to the Partnership for the fiscal years ended December 31, 2021, 2020 and 2019, as applicable. Other than for awards granted under the Plan, it is Sisecam Chemicals that has ultimate-decision making authority to determinate and approve the compensation program and individual compensation of the employees that perform services on our behalf, including the NEOs, and we reimburse Sisecam Chemicals for such services and compensation under the Services Agreement. Other than for awards granted under the Plan, the amounts reflected in the columns of the summary compensation table reflect the amounts we incurred for such services from the NEOs, in accordance with our Services Agreement with Sisecam Chemicals. We believe these expenses accurately reflect amounts paid to the NEOs as compensation for the services provided to us.

(1) The 2020 amounts in the “Bonus” column for Messrs. Erkan, DeBerry, Katekovich, Ms. Nicholson, and Mr. Freydel reflect the allocated portions of discretionary bonus payments Sisecam Chemicals made in recognition of the hard work and dedication exemplified during the unprecedented challenges faced by the organization during 2020, and for Mr. Tohma reflect a new hire bonus.

(2) The amounts shown in the “Unit Awards” column reflect the full aggregate grant date fair value of the performance-based unit awards and the restricted unit awards granted to the NEOs during the applicable period, as determined in accordance with ASC Topic 718, and as determined without regard to potential forfeitures (the amounts shown do not reflect the actual value that may be recognized by each NEO). For the restricted unit awards, the fair value per unit is equal to the closing sale price of our common units on the NYSE on the dates of the applicable grants ($16.45 on September 23, 2019). The grant date fair value for the 2019 performance-based unit awards was based on a per unit price of $16.45 on September 23, 2019. At maximum, the values of the 2019 performance-based unit awards for Mr. Erkan would be: $324,098; for Mr. DeBerry: $126,402; for Mr. Katekovich: $179,141; for Ms. Nicholson: $45,665; and for Mr. Freydel: $131,436 . For a discussion of the valuation assumptions applicable to the Unit Awards, please see Note 12 to our financial statements included in this Annual Report on Form 10-K for the year ended December 31, 2021.

(3) For the years ended December 31, 2021 and 2019, the amounts shown in this column reflect awards under Sisecam Chemicals Resources LLC’s Short-Term Bonus that were allocated to and reimbursed by us under the Services Agreement. The 2021 amounts represent payments that were earned in 2021 and paid by us in early 2022, and the 2019 amounts represent payments that were earned in 2019 and paid by us in early 2020.

The amount shown in this column for Mr. Tohma for 2020 also includes $23,932 for relocation expenses reimbursed directly to third party service providers in connection with his appointment of Chief Financial Officer and Principal Financial Officer of the Partnership in April 2020, which includes “gross-ups” for the related payment of taxes. For Mr. Freydel, the amount shown in the “All Other Compensation” column for 2021 includes $421,672 of severance paid in connection with his termination.

(5) Mr. Tohma became one of the NEOs upon appointment to Chief Financial Officer of our general partner in 2020. Consequently, compensation information was not reported for the prior years.

(6) Mr. Katekovich became one of the NEOs upon appointment to Vice President, Commercial and Corporate Strategy in 2020. Consequently, compensation information was not reported for prior years.

(7) Mr. Freydel resigned as Vice President Supply Chain and Finance of our general partner effective July 27, 2021 and as a result, outstanding unvested restricted unit awards and performance-based unit awards granted to him were forfeited.

(1) Calculated by multiplying the number of 2019 performance-based units awards, as applicable, reported in the preceding column by the closing price of our common units on the NYSE on December 31, 2021, which was $16.50, plus (i) for purposes of footnote (2) below included $2.607 in accrued distributions per common unit.

(2) These 2019 performance-based unit awards were awarded under the Plan on September 23, 2019, and vest, if at all, based on the Partnership’s performance relative to a pre-established budget over the applicable three-year performance period; provided, that the awardee remains continuously employed with our general partner or its affiliates or satisfies other service-related criteria through the end of the applicable three-year performance period and continued employment of the NEO with our general partner or its affiliates (or other service-related criteria) through the end of the applicable three-year performance period and certification of the results. Vesting fully accelerates upon a change in control of the Partnership or our general partner "(in the case of the Partnership’s 2019 performance award, vesting is also conditional upon the Partnership’s board approval), or the death or disability of the NEO. Vested 2019 performance-based unit awards are settled in our common units, with the number of units payable determined by multiplying the target number provided in the 2019 performance-based unit award agreement by a payout multiplier, which may range from 0% to 200%, in each case, determined by aggregating the corresponding weighted average assigned to the 2019 Award Performance Metrics. Upon any vesting of the 2019 performance-based unit awards, the NEO will also receive a cash payment equal to distribution equivalents that were accumulated with respect to vested 2019 performance-based unit awards during the period beginning on January 1, 2019 and ending on the applicable vesting date. The number of performance-based units that may be earned under this award.

(3) Mr. Freydel resigned as Vice President Supply Chain and Finance effective July 27, 2021 and, as a result, outstanding unvested restricted unit awards and 2019 performance-based unit awards granted to him were forfeited.

Nonqualified Deferred Compensation and Other Nonqualified Deferred Compensation Plans

Although neither we nor our general partner sponsors a nonqualified deferred compensation or other nonqualified deferred compensation plan, Sisecam Chemicals maintains a nonqualified deferred compensation plan for certain of its employees, including the NEOs, which we reimburse Sisecam Chemicals for a portion thereof allocated to us under the Services Agreement. The nonqualified deferred compensation plan allows individuals to defer up to 80% of their base pay and up to up to 100% of their Short-Term Bonus. In addition, Sisecam Chemicals contributes a matching contribution on compensation in excess of the dollar amount under Section 401(a)(17) of the IRS code ($290,000 for 2021). That matching contribution is equal to 100% of the first 4% that the NEO contributes to the plan and 50% of the next 2% that an individual contributes to the plan. Sisecam Chemicals. has historically also made an additional discretionary contribution to the plan for individuals hired on or after May 1, 2001. That additional discretionary contribution is equal to 3% of the annual base pay in excess of the dollar amount under Section 401(a)(17) of the IRS code ($290,000 for 2021), provided the individual is employed on December 31 for such year. The allocated expense for each NEO is included in the “All Other Compensation” column of the Summary Compensation Table above. The following table provides information on nonqualified deferred compensation of the NEOs as of December 31, 2021, for whom we reimburse Sisecam Chemicals under the Services Agreement.

(1) Mr. Freydel resigned as Vice President Supply Chain and Finance effective July 27, 2021 and, as a result, his entire balance in the nonqualified deferred compensation plan becomes payable in a lump sum on February 1, 2022.

Potential Payments upon Termination or Change-in-Control

In connection with the resignation by Mr. Freydel as the Vice President Supply Chain and Finance of our general partner, as a member of the Board and all committees thereof, and from other positions within the affiliates, Sisecam Chemicals entered into a Separation and Release Agreement (the “Separation Agreement”) with Mr. Freydel dated July 26, 2021. The Separation Agreement provides among other things, that Mr. Freydel’s employment with Ciner Group terminated on July 27, 2021. Subject to the terms and conditions set forth in the Separation Agreement, upon his termination, Sisecam Chemicals paid Mr. Freydel a one-time separation payment of $490,585 in the aggregate. In addition, Mr. Freydel was eligible to continue his health care coverage pursuant to the provisions of COBRA. The Separation Agreement also includes confidentiality and cooperation covenants, and a release of claims in favor of Ciner Group, the Partnership and our general partner, among other things. Other than the Separation Agreement, neither we, or general partner or Sisecam Group or Ciner Group have any employment agreements or severance agreements with the NEOs.

Our current restricted unit awards, TR performance-based unit awards and 2019 performance-based awards under the Plan and Short-Term Bonus and allocated to us contain provisions that could accelerate vesting of the award in certain situations, in the event of a (i) termination of an employee due to death or disability or (ii) a change in control (as described below). In the event of termination of employment for any other reason than described below, all restricted unit awards, TR performance-based unit awards and 2019 performance-based unit awards that are still unvested shall be forfeited.

performance-based unit awards and 2019 performance-based unit awards, in the event of the NEO’s death or disability during the three-year measurement period, then performance-based unit awards are resolved as follows:

(i) if such event occurs during the first year of the measurement period for the applicable TR performance-based unit awards or 2019 performance-based unit awards, as the case may be, all such applicable TR performance-based unit awards or 2019 performance-based unit awards and related accumulated distributions are forfeited for no consideration;

(ii) if such event occurs during second year of the measurement period for the applicable TR performance-based unit awards or 2019 performance-based unit awards, as the case may be, then such TR performance-based unit awards and 2019 performance-based unit awards and related accumulated distributions are earned and vested at 33% of the target units for such awards; and

(iii) if such event occurs, during the last year of the measurement period for the applicable TR performance-based unit awards or 2019 performance based unit awards, as the case may be, then such TR performance-based unit awards and 2019 performance-based unit awards and related accumulated distributions are earned and vested at 67% of the target units for such awards.

Pursuant to the terms of the award agreements issued under the Plan, for the TR performance-based unit awards and the 2019 performance-based unit awards, in the event of the NEO’s death or disability after the measurement period, but prior to the determination date for such TR performance-based unit awards or 2019 performance-based unit awards, as applicable, the participant’s outstanding TR performance-based unit awards or 2019 performance-based unit awards and the related distribution equivalents shall be earned and vest if at all, based on the attainment of such performance criteria, as determined by the administrator, with all remaining performance-based unit awards (and accumulated distributions associated with such performance-based unit awards) being immediately forfeited for no consideration.

The Short-Term Bonus does not provide for accelerated vesting in connection with a termination of employment for any reason.

Change in Control Benefits

Pursuant to the terms of the award agreements issued under the Plan, for the restricted unit awards and related cash distributions accumulated thereunder, in the event of a “Change in Control”, all restricted unit awards and related cash distributions accumulated thereunder shall become 100% vested. Pursuant to the terms of the award agreements issued under the Plan, for each of the TR performance-based unit awards and 2019 performance-based unit awards, in the event of a “Change in Control” then such TR performance-based unit awards or 2019 performance-based unit awards and the related cash distributions accumulated thereunder shall vest and forfeit as follows:

(i) in the event a Change of Control occurs before three-year measurement period has been completed, then the measurement period shall be deemed to end on the date of such Change in Control, and the participant’s outstanding TR performance-based unit awards or outstanding 2019 performance-based unit awards and the related distribution equivalents shall be earned and vest, if at all, based on the attainment of such performance criteria, as determined by the administrator, as if the measurement period ended on the date of the Change in Control and as if the ending unit prices were determined as of the date of the Change in Control, with all remaining TR performance-based unit awards or 2019 performance-based unit awards (and accumulated distributions associated with such TR performance-based unit awards or 2019 performance-based unit awards) being immediately forfeited for no consideration; and

(ii) in the event a Change in Control occurs after the three-year measurement period has been completed but prior to the determination date for such TR performance-based unit awards or 2019 performance-based unit awards, on the date of the Change in Control, the participant’s outstanding TR performance-based unit awards or 2019 performance-based unit awards and accumulated distributions associated with such TR performance-based unit awards or 2019 performance-based unit awards shall be earned and vest, if at all, based on the attainment of such performance criteria as described in TR performance unit awards or 2019 performance-based unit awards, as determined by the administrator of the Plan, with all remaining TR performance-based unit awards or 2019 performance-based unit awards (and accumulated distributions associated with such TR performance-based unit awards or 2019 performance-based unit awards) being immediately forfeited for no consideration; and

The Plan generally defines a “Change in Control” as occurring on one or more of the following events:

Table of Contents

clauses (i) and (ii) hereof, “Excluded Persons”), of more than fifty percent (50%) of the combined voting power of the Partnership’s or our general partner’s then outstanding voting securities;

Pursuant to the Short-Term Bonus, in the event of a “change in control” prior to the determination date thereunder, the participant’s outstanding awards under the Short-Term Bonus shall be paid their pro-rata portion of the applicable incentive award. To be eligible, a participant must be an active employee as of the date of the change in control. The pro-rata calculation will use the participant’s annual base salary in effect as of the date of the change in control and actual business results through the date of the change in control. The financial goals and the individual participation percentage will be pro-rated through the date of the change in control and no individual performance multiplier will apply. The Short-Term Bonus generally describes a “change in control” as occurring in the event that Sisecam Chemicals completes a direct or indirect sale to an unrelated third party of all or substantially all of the equity interests or assets in one of the businesses covered by the Short-Term Bonus.

The following table shows the amount of incremental value that would have been received by each of the NEOs upon certain events of termination or a “Change in Control” resulting in the accelerated vesting of our restricted units and performance based units held by the NEOs on December 31, 2021 and the amount of expense that could be allocated to us by Sisecam Chemicals under the Services Agreement in connection with certain events of termination or a “change in control” under the Short-Term Bonus, as if such event occurred on December 31, 2021. Actual amounts will be determinable only upon termination or a change in control event.

Director Compensation

Officers or employees of Sisecam Chemicals or its affiliates who also serve as directors of our general partner do not receive additional compensation for their service as a director of our general partner. Directors of our general partner who are not officers or employees of Sisecam Chemicals or its affiliates receive compensation as “non-employee directors.” For fiscal year ended December 31, 2021, our annual retainer for our non-employee directors consisted of approximately $165,000, of which $90,000 was paid in the form of an annual cash retainer and the remaining $75,000 was paid in a fully-vested grant of common units under the Plan. The lead director, audit committee chair and the conflicts committee chair were paid additional annual retainers of $10,000, $15,000 and $10,000, respectively. Each non-employee director that did not serve as a non-employee director for the entire fiscal year, received a prorated retainer reflecting their partial year of non-employee director service with us.

The following table summarizes the compensation paid to our non-employee directors for the fiscal year ended December 31, 2021.

ITEM 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information regarding the beneficial ownership of our common units as of March 10, 2022 owned by:

•each person known by us to be a beneficial owner of more than 5% of our units;

•each of the directors of our general partner;

•each of the named executive officers of our general partner; and

•all directors and executive officers of our general partner as a group.

The amounts and percentage of units beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under the rules of the SEC, a person is deemed to be a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment power,” which includes the power to dispose of or to direct the disposition of such security. Except as indicated by footnote, the persons named in the table below have sole voting and investment power with respect to all units shown as beneficially owned by them, subject to community property laws where applicable.

Percentage of total units beneficially owned is based on 19,788,208 common units and 399,000 general partner units outstanding. The list of beneficial owners is presented in the following table below:

ITEM 13. Certain Relationships and Related Transactions, and Director Independence

As of March 10, 2022, SCW LLC owned 14,551,000 common units representing an approximate 72% ownership interest in us, and owns and controls our general partner. In addition, our general partner owns general partner units representing an approximate 2% general partner interest in us and all of our incentive distribution rights.

The terms of the transactions and agreements disclosed in this section were determined by and among affiliated entities and, consequently, are not the result of arm’s length negotiations. These terms and agreements are not necessarily at least as favorable to us as the terms that could have been obtained from unaffiliated third parties.

Distributions and Payments to Our General Partner and Its Affiliates

The following table summarizes the distributions and payments to be made by us to our general partner and its affiliates in connection with the formation, ongoing operation and any liquidation of Sisecam Resources LP.

Operational Stage


Distributions to our general partner and its affiliates						We will generally make cash distributions 98.0% to our unitholders, pro rata, including our general partner and its affiliates as the holders of an aggregate of 14,551,000 common units, and approximately 2.0% to our general partner. In addition, if distributions exceed the minimum quarterly distribution and other higher target distribution levels, our general partner will be entitled to increasing percentages of the distributions, up to 48.0% of the distributions we make above the highest target distribution level.
Payments to our general partner and its affiliates						Sisecam Chemicals will receive a management fee in connection with our general partner’s management of us (as described in the section “Reimbursement of General and Administrative Expenses” below), and, prior to making any distribution on our common units, we will reimburse certain of its affiliates, including SCW LLC and Sisecam Chemicals, for all expenses they incur and payments they make on our behalf pursuant to the Services Agreement. Our partnership agreement does not set a limit on the amount of expenses for which our general partner and such affiliates may be reimbursed. These expenses may include salary, bonus, incentive compensation and other amounts paid to persons who perform services for us or on our behalf and expenses allocated to our general partner by such affiliates. Our partnership agreement provides that our general partner will determine in good faith the expenses that are allocable to us.
Withdrawal or removal of our general partner						If our general partner withdraws or is removed, its general partner interest and its incentive distribution rights will either be sold to the new general partner for cash or converted into common units, in each case for an amount equal to the fair market value of those interests.

Liquidation Stage


Liquidation						Upon our liquidation, the partners, including our general partner, will be entitled to receive liquidating distributions according to their particular capital account balances.

Indemnification Agreement

On October 23, 2015, in connection with the consummation of the Transaction, the Partnership amended and restated in its entirety, and renamed, that Omnibus Agreement (as amended and restated, the “Indemnification Agreement”), dated September 18, 2013, among the Partnership, our general partner and OCI Enterprises. Pursuant to the Indemnification Agreement, OCI Enterprises agreed to continue to indemnify the Partnership for issues arising out of, including but not limited to, certain tax liabilities relating to the period before the Partnership’s initial public offering and assets retained by OCI Enterprises and its affiliates.

Services Agreement

On October 23, 2015, Ciner Enterprises indirectly acquired OCI Enterprises Inc.’s approximately 73% limited partner interest in the Partnership, as well as its 2% general partner interest and related incentive distribution rights (the “OCI Transaction”). Further, in connection with the closing of the OCI Transaction, the Partnership entered into the Services Agreement among the Partnership, our general partner and Sisecam Chemicals. Pursuant to the Services Agreement, Sisecam Chemicals agreed to provide the Partnership with certain corporate, selling, marketing, and general and administrative services, in return for which the Partnership has agreed to pay Sisecam Chemicals an annual management fee, subject to quarterly adjustments, and reimburse Sisecam Chemicals for certain third-party costs incurred in connection with providing such services.

Trademark License Agreement

In connection with the closing of the Transaction on October 23, 2015, the Partnership also entered into the Trademark License Agreement, among Park Holding, Akkan, Ciner Enterprises, Sisecam Chemicals, SCW LLC, the Partnership, our general partner and Sisecam Wyoming. The Trademark License Agreement governs the use of “Ciner” as part of the names used by the Partnership and the other related parties thereto following the Transaction, and as a trademark and service mark, for the Partnership’s products and services.

Reimbursement of General and Administrative Expense

Under the Services Agreement, we pay Sisecam Chemicals for services provided to us, and we also reimburse Sisecam Chemicals for certain third-party costs incurred in connection with providing such services. We also reimburse Sisecam Chemicals for our allocable portion of the premiums on any insurance policies covering our assets and for any additional state income, franchise or similar tax paid by Ciner Enterprises resulting from the inclusion of us (and our subsidiaries) in a combined state income, franchise or similar tax report with Sisecam Chemicals as required by applicable law.

Transactions with Affiliates

Sisecam Chemicals and Sisecam Wyoming are party to a sales agency agreement dated June 17, 2015. Under the sales agency agreement, Sisecam Chemicals contracts with customers, including ANSAC and Ciner Group, for the sale of the soda ash that Sisecam Wyoming produces, and Sisecam Wyoming delivers soda ash directly to the customers. Though Sisecam Chemicals is the contractual party with customers, any risk of loss related to soda ash is passed directly to Sisecam Wyoming, except in circumstances where the buyer takes ownership of soda ash at the shipping point. Sisecam Wyoming invoices the customers, and risk of loss from collecting accounts receivable remains with Sisecam Wyoming. Sisecam Wyoming also bears any risk of loss from liability claims related to soda ash. Sisecam Chemicals receives sales proceeds directly from customers on behalf of Sisecam Wyoming, and Sisecam Chemicals then transfers the total proceeds of the sales directly to Sisecam Wyoming, less Sisecam Chemicals’ actual costs of sales and marketing. Sisecam Chemicals’ costs are allocated to Sisecam Wyoming by OCI Enterprises (prior to the OCI Transaction) and Sisecam Chemicals (subsequent to the OCI Transaction) based on the amount of time spent by Sisecam Chemicals providing such services. For the years ended December 31, 2021, 2020 and 2019, these charges amounted to approximately $17.2 million, $16.1 million and $14.9 million, respectively. Sisecam Chemicals also contracts with various land and sea carriers for freight transportation on behalf of Sisecam Wyoming. All such actual freight costs are charged directly to Sisecam Wyoming.

Substantially all of Sisecam Wyoming’s selling and marketing expenses and general and administrative expenses are expenses charged to Sisecam Wyoming by Sisecam Chemicals for actual expenses incurred by it on behalf of Sisecam Wyoming and include expenses relating to salaries, benefits, office supplies, professional fees, travel, computers and rent.

Prior to 2021, Sisecam Chemicals was a member company of ANSAC and had an approximate 34.9% and 38.2% participation interest at December 31, 2020 and 2019, respectively. We made approximately 21.1%, 45.4% and 60.4% of our total net sales for the years ended December 31, 2021, 2020 and 2019, respectively, to ANSAC. In addition, prior to 2021, ANSAC provided logistics and support services for all of our export sales during the period the Partnership was a member of ANSAC. On July 27,

Table of Contents

2020, ANSAC and the members thereof entered into an agreement, effective as of July 24, 2020, that, among other things, terminated Sisecam Chemicals’ membership in ANSAC effective as of December 31, 2020. The conflicts committee met three times in 2020 to deliberate on and approve proposed affiliate transactions for post-ANSAC operations that went into effect starting January 2021. See Item 1, Business, “Shipping and Logistics,” for more information.

The personnel who operate our assets are employees of Sisecam Chemicals and its affiliates. Sisecam Chemicals directly charges us for the payroll and benefit costs associated with employees and carried the obligations for other employee-related benefits in its financial statements. We are allocated a portion of Sisecam Chemicals’ defined benefit pension plan liability and postretirement benefit liability for the employees providing services to us based on an actuarial assessment of that liability. See Item 8, Financial Statements and Supplementary Data, Note 11, “Employee Compensation,” for more information. In addition, under the joint venture agreement governing Sisecam Wyoming, Sisecam Wyoming reimburses us for employees who operate our assets and for support provided to Sisecam Wyoming.

Procedures for Review, Approval and Ratification of Transactions with Related Persons

As disclosed under “Item 10. Directors, Executive Officers and Corporate Governance,” our audit committee has been given the sole authority, under the audit committee charter, to review and evaluate any related party transactions or dealings with parties related to us and disclosures of such transactions or dealings in our annual report on Form 10-K, and our conflicts committee is responsible, under the conflicts committee charter, with reviewing specific matters that may involve conflicts of interest between our general partner or any of its affiliates, on the one hand, and us, our partners and any of our subsidiaries, on the other hand, in accordance with the terms of our partnership agreement. Any matters approved by our conflicts committee in good faith will be deemed to be approved by all of our partners and not a breach by our general partner of any duties it may owe us or our unitholders.

Director Independence

GLOSSARY OF INDUSTRY TERMS

ANSAC: American Natural Soda Ash Corporation, a U.S. export cooperative organized under the provisions of the Webb-Pomerene Act of 1918.

Calciner: A large furnace used to heat and bring about thermal decomposition of trona.

Continuous Miner: A machine with a large rotating steel drum equipped with tungsten carbide teeth that scrapes trona from a mining bed seam.

Deca: Sodium carbonate decahydrate, a natural by-product of trona ore processing.

Effective Capacity: The volume of soda ash that can be generated using current operational resources, taking into account scheduled and unscheduled downtime and idled capacity.

IDRs: Incentive Distribution Rights represents the general partner’s right to receive increasing percentages of quarterly distributions from operating surplus after the Partnership has achieved the minimum quarterly distribution and the target distribution levels.

Liquor: A solution consisting of sodium carbonate dissolved in water.

Mining Bed: A layer or stratum of trona.

Mining Face: The exposed area of an underground mine from which trona is extracted.

MMBtu: Million British thermal units.

MSHA: Mine Safety and Health Administration.

Non-subsidence mining: Any one of several mining techniques designed to prevent or avoid the collapse of the surface above the mine. Room and pillar mining, which leaves “pillars” to support the roof of a mine, is a form of non-subsidence mining.

Operating Rate: The amount of soda ash produced in a given year as a percentage of effective capacity for that year.

Ore to Ash Ratio: The number of short tons of trona ore it takes to produce one short ton of soda ash.

Ore Grade: Ore grade is the percentage of raw trona ore that is recoverable as soda ash free of impurities. A higher ore grade will produce more soda ash than a lower ore grade.

Purged Liquor: Liquor expelled into collection ponds during trona ore processing.

Recovery Rate: An amount, expressed as a percentage, calculated by dividing the volume of dry soda ash produced by the sum of the volume of dry soda ash produced and the losses experienced in the refinery process.

Room and Pillar Mining: A mining method wherein underground mineral seams are mined in a network of “rooms.” As these rooms are cut and formed, continuous miners simultaneously load trona onto shuttle cars for hoisting to the surface. “Pillars” composed of trona are left behind in these rooms to support the roofs of the mines. Room and pillar mining is often used to mine smaller blocks or center seams.

Run-of-Mine: The amount of trona removed directly from the mine prior to processing.

Seam: Trona deposits occur in layers typically separated by layers of rock. Each layer of trona is called a “seam.”

Soda Ash: Sodium carbonate (Na2CO3) in a powder form.

Tailings Disposal: Disposal of materials left over after the process of separating the soluble portion of trona ore from the non-soluble portion of trona ore.

Trona: Sodium sesquicarbonate (Na2CO3-NaHCO3-2H2O), a naturally occurring soft mineral, consisting primarily of sodium carbonate, or soda ash, sodium bicarbonate and water.

Trona Ore: Trona that has been removed from the ground.
