Forward-Looking Statements

This Quarterly Report on Form 10-Q includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Statements included in this quarterly report that are not historical facts (including any statements concerning plans and objectives of management for future operations or economic performance, or assumptions or forecasts related thereto), including, without limitation, the information set forth in Management’s Discussion and Analysis of Financial Condition and Results of Operations, are forward-looking statements. These statements can be identified by the use of forward-looking terminology including "forecast," "may," "believe," "will," "expect," "anticipate," "estimate," "continue," or other similar words. These statements discuss future expectations, contain projections of results of operations or of financial condition or state other "forward-looking" information. We and our representatives may from time to time make other oral or written statements that are also forward-looking statements.

These forward-looking statements are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements.

Because these forward-looking statements involve risks and uncertainties, actual results could differ materially from those expressed or implied by these forward-looking statements for a number of important reasons, including those discussed under "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the Securities and Exchange Commission (the "SEC") on March 3, 2021, and as may be updated and supplemented from time to time in our future Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.

NOTE 1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION

Martin Midstream Partners L.P. (the "Partnership") is a publicly traded limited partnership with a diverse set of operations focused primarily in the United States ("U.S.") Gulf Coast region. Its four primary business lines include: terminalling, processing, storage and packaging services for petroleum products and by-products including the refining of naphthenic crude oil; land and marine transportation services for petroleum products and by-products, chemicals, and specialty products; sulfur and sulfur-based products processing, manufacturing, marketing and distribution; and natural gas liquids marketing, distribution, and transportation services.

The Partnership’s unaudited consolidated and condensed financial statements have been prepared in accordance with the requirements of Form 10-Q and U.S. Generally Accepted Accounting Principles ("U.S. GAAP") for interim financial reporting. Accordingly, these financial statements have been condensed and do not include all of the information and footnotes required by U.S. GAAP for annual audited financial statements of the type contained in the Partnership’s annual reports on Form 10-K. In the opinion of the management of the Partnership’s general partner, all adjustments and elimination of significant intercompany balances necessary for a fair presentation of the Partnership’s financial position, results of operations, and cash flows for the periods shown have been made. All such adjustments are of a normal recurring nature. Results for such interim periods are not necessarily indicative of the results of operations for the full year. These financial statements should be read in conjunction with the Partnership’s audited consolidated financial statements and notes thereto included in the Partnership’s annual report on Form 10-K for the year ended December 31, 2020, filed with the SEC on March 3, 2021.

Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these consolidated and condensed financial statements in conformity with U.S. GAAP. Actual results could differ from those estimates.

NOTE 2. NEW ACCOUNTING PRONOUNCEMENTS

On January 1, 2021, the Partnership adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2019-12, Income Taxes (Accounting Standards Codification ("ASC") Topic 740): Simplifying the Accounting for Income Taxes, which removes certain exceptions to general principles in ASC 740 and clarifies and amends existing guidance within U.S. GAAP. Adoption of the new standard did not have a material impact on the Partnership’s consolidated financial statements.

Revenue is measured based on a consideration specified in a contract with a customer and excludes amounts collected on behalf of third parties where the Partnership is acting as an agent. The Partnership recognizes revenue when the Partnership satisfies a performance obligation, which typically occurs when the Partnership transfers control over a product to a customer or as the Partnership delivers a service.

The following is a description of the principal activities - separated by reportable segments - from which the Partnership generates revenue.

Terminalling and Storage Segment

Revenue is recognized for storage contracts based on the contracted monthly tank fixed fee. For throughput contracts, revenue is recognized based on the volume moved through the Partnership’s terminals at the contracted rate. For the Partnership’s tolling agreement, revenue is recognized based on the contracted monthly reservation fee and throughput volumes moved through the facility. When lubricants and drilling fluids are sold by truck or rail, revenue is recognized when title is transferred, which is either upon delivering product to the customer or when the product leaves the Partnership's facility, depending on the specific terms of the contract. Delivery of product is invoiced as the transaction occurs and is generally paid within a month. Throughput and storage revenue in the table above includes non-cancelable revenue arrangements that are under the scope of ASC 842, whereby the Partnership has committed certain Terminalling and Storage assets in exchange for a minimum fee.

Natural Gas Liquids Segment

Natural Gas Liquids ("NGL") revenue is recognized when product is delivered by truck, rail, or pipeline to the Partnership's NGL customers. Revenue is recognized on title transfer of the product to the customer. Delivery of product is invoiced as the transaction occurs and is generally paid within a month.

(Unaudited)

Sulfur Services Segment

Revenue from sulfur and fertilizer product sales is recognized when the customer takes title to the product. Delivery of product is invoiced as the transaction occurs and is generally paid within a month. Revenue from sulfur services is recognized as services are performed during each monthly period. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

Transportation Segment

Revenue related to land transportation is recognized for line hauls based on a mileage rate. For contracted trips, revenue is recognized upon completion of the particular trip. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

Revenue related to marine transportation is recognized for time charters based on a per day rate. For contracted trips, revenue is recognized upon completion of the particular trip. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

The table below includes estimated minimum revenue expected to be recognized in the future related to performance obligations that are unsatisfied at the end of the reporting period. The Partnership applies the practical expedient in ASC 606-10-50-14(a) and does not disclose information about remaining performance obligations that have original expected durations of one year or less.

1 Interest rate fluctuates based on LIBOR or the base prime rate (set on the date of each advance) plus an applicable margin. The margin is set every three months. All amounts outstanding at December 31, 2020 and June 30, 2021 were at LIBOR plus an applicable margin with LIBOR having a floor of 1.0% per annum. The applicable margin for revolving loans that are LIBOR loans currently ranges from 2.75% to 4.00%, and the applicable margin for revolving loans that are base prime rate loans currently ranges from 1.75% to 3.00%. The applicable margin for LIBOR borrowings at June 30, 2021 is 4.00%. The credit facility contains various covenants that limit the Partnership’s ability to make distributions; make certain investments and acquisitions; enter into certain agreements; incur indebtedness; sell assets; and make certain amendments to the Partnership's omnibus agreement with Martin Resource Management Corporation (the "Omnibus Agreement"). The credit facility was amended on July 16, 2021 to, among other things, reduce the commitments thereunder from $300,000 to $275,000.

2 The Partnership is in compliance with all debt covenants as of June 30, 2021 and December 31, 2020, respectively.

3 The indentures for each of the outstanding series of senior notes restrict the Partnership’s ability to sell assets; pay distributions or repurchase units or redeem or repurchase subordinated debt; make investments; incur or guarantee additional indebtedness or issue preferred units; and consolidate, merge or transfer all or substantially all of its assets.

4 On February 15, 2021, the 2021 Notes matured and the Partnership retired the outstanding balance of $28,790 using funds borrowed under its revolving credit facility.

The Partnership paid cash interest, net of capitalized interest, in the amount of $2,648 and $2,376 for the three months ended June 30, 2021 and 2020, respectively. The Partnership paid cash interest, net of capitalized interest, in the amount of $25,995 and $19,113 for the six months ended June 30, 2021 and 2020, respectively. Capitalized interest was $0 and $6 for the three months ended June 30, 2021 and 2020, respectively. Capitalized interest was $0 and $9 for the six months ended June 30, 2021 and 2020, respectively.

NOTE 6. LEASES

The Partnership has numerous operating leases primarily for terminal facilities and transportation and other equipment. The leases generally provide that all expenses related to the equipment are to be paid by the lessee.

Operating lease Right-of-Use assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. Because most of the Partnership's leases do not provide an implicit rate of return, the Partnership uses its imputed collateralized rate based on the information available at commencement date in determining the present value of lease payments. The estimated rate is based on a risk-free rate plus a risk-adjusted margin.

Our leases have remaining lease terms of 1 year to 15 years, some of which include options to extend the leases for up to 5 years, and some of which include options to terminate the leases within 1 year. The Partnership includes extension periods and excludes termination periods from its lease term if, at commencement, it is reasonably likely that the Partnership will exercise the option.

The components of lease expense for the three and six months ended June 30, 2021 and 2020 were as follows:


	Three Months Ended June 30,				Six Months Ended June 30,

NOTE 8. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Partnership’s results of operations could be materially impacted by changes in commodity prices and interest rates. In an effort to manage its exposure to these risks, the Partnership periodically enters into various derivative instruments, including commodity and interest rate hedges. All derivatives and hedging instruments are non-hedge derivatives and are included on the balance sheet as an asset or a liability measured at fair value, and changes in fair value are recognized as gains and losses in the earnings of the periods in which they occur.

(a) Commodity Derivative Instruments

The Partnership from time to time has used derivatives to manage the risk of commodity price fluctuation. Commodity risk is the adverse effect on the value of a liability or future purchase that results from a change in commodity price. The Partnership has established a hedging policy and monitors and manages the commodity market risk associated with potential commodity risk exposure. In addition, the Partnership has focused on utilizing counterparties for these transactions whose financial condition is appropriate for the credit risk involved in each specific transaction. The Partnership has entered into hedging transactions as of June 30, 2021, to protect a portion of its commodity price risk exposure. These hedging arrangements are in the form of swaps for NGLs. At June 30, 2021, the Partnership had instruments totaling a gross notional quantity of 390,000 barrels settling during the period from July 31, 2021 through December 31, 2021. At December 31, 2020, the Partnership had instruments totaling a gross notional quantity of 137,000 barrels settling during the period from January 31, 2021 through February 28, 2021. These instruments settle against the applicable pricing source for each grade and location.

For information regarding gains and losses on interest rate derivative instruments, see "Tabular Presentation of Gains and Losses on Derivative Instruments" below.

(b) Tabular Presentation of Gains and Losses on Derivative Instruments

The following table summarizes the fair value and classification of the Partnership’s derivative instruments in its Consolidated and Condensed Balance Sheets:

NOTE 9. PARTNERS' CAPITAL

As of June 30, 2021, Partners’ capital consisted of 38,802,750 common limited partner units, representing a 98% partnership interest, and a 2% general partner interest. Martin Resource Management Corporation, through subsidiaries, owns 6,114,532 of the Partnership's common limited partner units representing approximately 15.8% of the Partnership's outstanding common limited partner units. Martin Midstream GP LLC ("MMGP"), the Partnership's general partner, owns the 2% general partnership interest. Martin Resource Management Corporation controls the Partnership's general partner, by virtue of its 51% voting interest in MMGP Holdings, LLC ("Holdings"), the sole member of the Partnership's general partner.

The partnership agreement of the Partnership (the "Partnership Agreement") contains specific provisions for the allocation of net income and losses to each of the partners for purposes of maintaining their respective partner capital accounts.

Impact on Partners' Capital (Deficit) Related to Transactions Between Entities Under Common Control

Under ASC 805, assets and liabilities transferred between entities under common control are accounted for at the historical cost of those entities' ultimate parent, in a manner similar to a pooling of interests. Any difference in the amount paid by the transferee versus the historical cost of the assets transferred is recorded as an adjustment to equity (contribution or distribution) by the transferee. This is in contrast with a business combination between unrelated parties, where assets and liabilities are recorded at their fair values at the acquisition date, with any excess of amounts paid over the fair value representing goodwill. From time to time, the most recent being in 2019, the Partnership has entered into common control acquisitions from Martin Resource Management Corporation. The consideration transferred totaling $550,773 exceeds the historical cost of the net assets received. This excess of the purchase price over the historical cost of the net assets received has resulted in cumulative distributions of $287,734 reflected as reductions to Partners' capital.

Incentive Distribution Rights

MMGP holds a 2% general partner interest and certain incentive distribution rights ("IDRs") in the Partnership. IDRs are a separate class of non-voting limited partner interest that may be transferred or sold by the general partner under the terms of the Partnership Agreement, and represent the right to receive an increasing percentage of cash distributions after the minimum quarterly distribution and any cumulative arrearages on common units once certain target distribution levels have been achieved. The Partnership is required to distribute all of its available cash from operating surplus, as defined in the Partnership Agreement. The general partner was allocated no incentive distributions during the six months ended June 30, 2021 and 2020.

The target distribution levels entitle the general partner to receive 2% of quarterly cash distributions from the minimum of $0.50 per unit up to $0.55 per unit, 15% of quarterly cash distributions in excess of $0.55 per unit until all unitholders have received $0.625 per unit, 25% of quarterly cash distributions in excess of $0.625 per unit until all unitholders have received $0.75 per unit and 50% of quarterly cash distributions in excess of $0.75 per unit.

Distributions of Available Cash

The Partnership distributes all of its available cash (as defined in the Partnership Agreement) within 45 days after the end of each quarter to unitholders of record and to the general partner. Available cash is generally defined as all cash and cash equivalents of the Partnership on hand at the end of each quarter less the amount of cash reserves its general partner determines in its reasonable discretion is necessary or appropriate to: (i) provide for the proper conduct of the Partnership’s business; (ii) comply with applicable law, any debt instruments or other agreements; or (iii) provide funds for distributions to unitholders and the general partner for any one or more of the next four quarters, plus all cash on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.

Net Income per Unit

The Partnership follows the provisions of the FASB ASC 260-10 related to earnings per share, which addresses the application of the two-class method in determining income per unit for master limited partnerships having multiple classes of securities that may participate in partnership distributions accounted for as equity distributions. Undistributed earnings are allocated to the general partner and limited partners utilizing the contractual terms of the Partnership Agreement. Distributions to the general partner pursuant to the IDRs are limited to available cash that will be distributed as defined in the Partnership Agreement. Accordingly, the Partnership does not allocate undistributed earnings to the general partner for the IDRs because the general partner's share of available cash is the maximum amount that the general partner would be contractually entitled to receive if all earnings for the period were distributed. When current period distributions are in excess of earnings, the excess distributions for the period are to be allocated to the general partner and limited partners based on their respective sharing of income and losses specified in the Partnership Agreement. Additionally, as required under FASB ASC 260-10-45-61A, unvested share-based payments that entitle employees to receive non-forfeitable distributions are considered participating securities, as defined in FASB ASC 260-10-20, for earnings per unit calculations.

For purposes of computing diluted net income per unit, the Partnership uses the more dilutive of the two-class and if-converted methods. Under the if-converted method, the weighted-average number of subordinated units outstanding for the period is added to the weighted-average number of common units outstanding for purposes of computing basic net income per unit and the resulting amount is compared to the diluted net income per unit computed using the two-class method. The following is a reconciliation of net income allocated to the general partner and limited partners for purposes of calculating net income attributable to limited partners per unit:

Total weighted average limited partner diluted units outstanding	38,687,874	38,661,852	38,690,228	38,651,897

All outstanding units were included in the computation of diluted earnings per unit and weighted based on the number of days such units were outstanding during the periods presented. All common unit equivalents were antidilutive for the three and six months ended June 30, 2021 and the three months ended June 30, 2020 because the limited partners were allocated a net loss in this period.

NOTE 10. UNIT BASED AWARDS

The Partnership recognizes compensation cost related to unit-based awards to both employees and non-employees in its consolidated and condensed financial statements in accordance with certain provisions of ASC 718. Amounts recognized in selling, general, and administrative expense in the consolidated and condensed financial statements with respect to these plans are as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Employees	$	—	$	301	$	194	$	602
Non-employee directors	48		62		94		107
Total unit-based compensation expense	$	48	$	363	$	288	$	709

All of the Partnership's outstanding awards at June 30, 2021 met the criteria to be treated under equity classification.

Long-Term Incentive Plans

The Partnership's general partner has a long-term incentive plan for employees and directors of the general partner and its affiliates who perform services for the Partnership.

On May 26, 2017, the unitholders of the Partnership approved the Martin Midstream Partners L.P. 2017 Restricted Unit Plan (the "2017 LTIP"). The 2017 LTIP currently permits the grant of awards covering an aggregate of 3,000,000 common units, all of which can be awarded in the form of restricted units. The 2017 LTIP is administered by the compensation committee of the general partner’s board of directors (the "Compensation Committee").

A restricted unit is a unit that is granted to grantees with certain vesting restrictions, which may be time-based and/or performance-based. Once these restrictions lapse, the grantee is entitled to full ownership of the unit without restrictions. The Compensation Committee may determine to make grants under the plan containing such terms as the Compensation Committee shall determine under the plan. With respect to time-based restricted units ("TBRUs"), the Compensation Committee will determine the time period over which restricted units granted to employees and directors will vest. The Compensation Committee may also award a percentage of restricted units with vesting requirements based upon the achievement of specified pre-established performance targets ("Performance Based Restricted Units" or "PBRUs"). The performance targets may include, but are not limited to, the following: revenue and income measures, cash flow measures, net income before interest expense and income tax expense ("EBIT"), net income before interest expense, income tax expense, and depreciation and amortization ("EBITDA"), distribution coverage metrics, expense measures, liquidity measures, market measures, corporate sustainability metrics, and other measures related to acquisitions, dispositions, operational objectives and succession planning objectives. PBRUs are earned only upon our achievement of an objective performance measure for the performance period. PBRUs which vest are payable in common units. Unvested units granted under the 2017 LTIP may or may not participate in cash distributions depending on the terms of each individual award agreement.

The performance conditions related to the PBRUs awarded on March 1, 2018 were not achieved and the Partnership treated these units as forfeited at expiration on March 31, 2021. As such, the Partnership did not recognize compensation expense related to these units.

The restricted units issued to directors generally vest in equal annual installments over a four-year period. Restricted units issued to employees generally vest in equal annual installments over three years of service.

In February 2021, the Partnership issued 14,056 TBRUs to each of the Partnership's three independent directors under the 2017 LTIP. These restricted common units vest in equal installments of 3,514 units on January 24, 2022, 2023, 2024, and 2025.

The restricted units are valued at their fair value at the date of grant, which is equal to the market value of common units on such date. A summary of the restricted unit activity for the six months ended June 30, 2021 is provided below:


	Number of Units		Weighted Average Grant-Date Fair Value Per Unit
Non-vested, beginning of period	273,424		$	10.52
Granted (TBRU)	42,168		$	2.49

Vested	(117,280)		$	11.96
Forfeited	(83,436)		$	13.90
Non-Vested, end of period	114,876		$	3.65

Aggregate intrinsic value, end of period	$	347

A summary of the restricted units’ aggregate intrinsic value (market value at vesting date) and fair value of units vested (market value at date of grant) during the three and six months ended June 30, 2021 and 2020 is provided below:


	Three Months Ended June 30,				Six Months Ended June 30,

Fair value of units vested	—		—		1,418		1,427

As of June 30, 2021, there was $344 of unrecognized compensation cost related to non-vested restricted units. That cost is expected to be recognized over a weighted-average period of 2.42 years.

NOTE 11. RELATED PARTY TRANSACTIONS

As of June 30, 2021, Martin Resource Management Corporation owns 6,114,532 of the Partnership’s common units representing approximately 15.8% of the Partnership’s outstanding limited partner units. Martin Resource Management Corporation controls the Partnership's general partner by virtue of its 51% voting interest in Holdings, the sole member of the Partnership's general partner. The Partnership’s general partner, MMGP, owns a 2% general partner interest in the Partnership and the Partnership’s IDRs. The Partnership’s general partner’s ability, as general partner, to manage and operate the Partnership, and Martin Resource Management Corporation’s ownership as of June 30, 2021, effectively gives Martin Resource Management Corporation the ability to veto some of the Partnership’s actions and to control the Partnership’s management.

Services. Under the Omnibus Agreement, Martin Resource Management Corporation provides the Partnership with corporate staff, support services, and administrative services necessary to operate the Partnership’s business. The Omnibus Agreement requires the Partnership to reimburse Martin Resource Management Corporation for all direct expenses it incurs or payments it makes on the Partnership’s behalf or in connection with the operation of the Partnership’s business. There is no monetary limitation on the amount the Partnership is required to reimburse Martin Resource Management Corporation for direct expenses. In addition to the direct expenses, under the Omnibus Agreement, the Partnership is required to reimburse Martin Resource Management Corporation for indirect general and administrative and corporate overhead expenses.

Effective January 1, 2021, through December 31, 2021, the Conflicts Committee approved an annual reimbursement amount for indirect expenses of $14,386. The Partnership reimbursed Martin Resource Management Corporation for $3,652 and $4,103 of indirect expenses for the three months ended June 30, 2021 and 2020, respectively. The Partnership reimbursed Martin Resource Management Corporation for $7,193 and $8,261 of indirect expenses for the six months ended June 30, 2021 and 2020, respectively. The Conflicts Committee will review and approve future adjustments in the reimbursement amount for indirect expenses, if any, annually.

These indirect expenses are intended to cover the centralized corporate functions Martin Resource Management Corporation provides to the Partnership, such as accounting, treasury, clerical, engineering, legal, billing, information technology, administration of insurance, general office expenses and employee benefit plans and other general corporate overhead functions the Partnership shares with Martin Resource Management Corporation retained businesses. The provisions of the Omnibus Agreement regarding Martin Resource Management Corporation’s services will terminate if Martin Resource Management Corporation ceases to control the general partner of the Partnership.

Related Party Transactions. The Omnibus Agreement prohibits the Partnership from entering into any material agreement with Martin Resource Management Corporation without the prior approval of the Conflicts Committee. For purposes of the Omnibus Agreement, the term "material agreements" means any agreement between the Partnership and Martin Resource Management Corporation that requires aggregate annual payments in excess of the then-applicable agreed upon reimbursable amount of indirect general and administrative expenses. Please read "Services" above.

License Provisions. Under the Omnibus Agreement, Martin Resource Management Corporation has granted the Partnership a nontransferable, nonexclusive, royalty-free right and license to use certain of its trade names and marks, as well as the trade names and marks used by some of its affiliates.

Amendment and Termination. The Omnibus Agreement may be amended by written agreement of the parties; provided, however, that it may not be amended without the approval of the Conflicts Committee if such amendment would

The Omnibus Agreement was amended further on October 1, 2012, to permit the Partnership to provide certain lubricant packaging products and services to Martin Resource Management Corporation. Such amendments were approved by the Conflicts Committee. The Omnibus Agreement, other than the indemnification provisions and the provisions limiting the amount for which the Partnership will reimburse Martin Resource Management Corporation for general and administrative services performed on its behalf, will terminate if the Partnership is no longer an affiliate of Martin Resource Management Corporation.

Master Transportation Services Agreement

Marine Agreements

Marine Transportation Agreement. The Partnership is a party to a marine transportation agreement effective January 1, 2006, as amended, under which the Partnership provides marine transportation services to Martin Resource Management Corporation on a spot-contract basis at applicable market rates. Effective each January 1, this agreement automatically renews for consecutive one year periods unless either party terminates the agreement by giving written notice to the other party at least 60 days prior to the expiration of the then applicable term.

Terminal Services Agreements

Diesel Fuel Terminal Services Agreement. Effective January 1, 2016, the Partnership entered into a second amended and restated terminalling services agreement under which the Partnership provides terminal services to Martin Resource Management Corporation for marine fuel distribution. At such time, the per-gallon throughput fee the Partnership charged under this agreement was increased when compared to the previous agreement and may be adjusted annually based on a price index. This agreement was further amended on January 1, 2017, October 1, 2017, April 1, 2019, and January 1, 2020 to modify its minimum throughput requirements and throughput fees. The term of this agreement is currently evergreen and it will continue on a month to month basis until terminated by either party by giving 60 days’ written notice.

Miscellaneous Terminal Services Agreements. The Partnership is currently party to several terminal services agreements and from time to time the Partnership may enter into other terminal service agreements for the purpose of providing terminal services to related parties. Individually, each of these agreements is immaterial but when considered in the aggregate they could be deemed material. These agreements are throughput based with a minimum volume commitment. Generally, the fees due under these agreements are adjusted annually based on a price index.

Other Agreements

Cross Tolling Agreement. The Partnership is a party to an amended and restated tolling agreement with Cross Oil Refining and Marketing, Inc. ("Cross") dated October 28, 2014, under which the Partnership processes crude oil into finished products, including naphthenic lubricants, distillates, asphalt and other intermediate cuts for Cross. The tolling agreement expires November 25, 2031. Under this tolling agreement, Cross agreed to process a minimum of 6,500 barrels per day of crude oil at the facility at a fixed price per barrel. Any additional barrels are processed at a modified price per barrel. In addition, Cross agreed to pay a monthly reservation fee and a periodic fuel surcharge fee based on certain parameters specified in the tolling agreement. Further, certain capital improvements, to the extent requested by Cross, are reimbursed through a capital recovery fee. As of December 31, 2019, the annual capital recovery fee reimbursement of $2,088 expired. An additional $2,586 of capital recovery fee reimbursement expired on December 31, 2020. All of these fees (other than the fuel surcharge and capital recovery fee) are subject to escalation annually based upon the greater of 3% or the increase in the Consumer Price Index for a specified annual period. Also, the Partnership renegotiated a crude transportation contract set to expire in the first half of 2022, resulting in a reduction in revenue of $2,145 annually beginning January 1, 2020.

East Texas Mack Leases. MTI leases equipment, including tractors and trailers, from East Texas Mack Sales ("East Texas Mack"). Certain of our directors or officers are owners of East Texas Mack, including entities affiliated with Ruben Martin, who owns approximately 46% of the issued and outstanding stock of East Texas Mack. Amounts paid to East Texas Mack for tractor and trailer lease payments and lease residuals for the three months ended June 30, 2021 and 2020 were $282 and $154, respectively.

NOTE 12. BUSINESS SEGMENTS

The Partnership has four reportable segments: terminalling and storage, transportation, sulfur services and natural gas liquids. The Partnership’s reportable segments are strategic business units that offer different products and services. The operating income of these segments is reviewed by the chief operating decision maker to assess performance and make business decisions.

The accounting policies of the operating segments are the same as those described in Note 2 in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on March 3, 2021. The Partnership evaluates the performance of its reportable segments based on operating income. There is no allocation of administrative expenses or interest expense.

NOTE 13. COMMITMENTS AND CONTINGENCIES

Contingencies

From time to time, the Partnership is subject to various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Partnership.

On December 31, 2015, the Partnership received a demand from a customer in its lubricants packaging business for defense and indemnity in connection with lawsuits filed against it in various United States District Courts, which generally allege that the customer engaged in unlawful and deceptive business practices in connection with its marketing and advertising of its private label motor oil. The Partnership disputes that it has any obligation to defend or indemnify the customer for its conduct. Accordingly, on January 7, 2016, the Partnership filed a Complaint for Declaratory Judgment in the Chancery Court of Davidson County, Tennessee requesting a judicial determination that the Partnership does not owe the customer the demanded defense and indemnity obligations. The lawsuits against the customer have been transferred to the United States District Court for the Western District of Missouri for consolidated pretrial proceedings. On March 1, 2017, at the request of the parties, the Chancery Court of Davidson County, Tennessee administratively closed the Partnership's lawsuit pending rulings in the United States District Court for the Western District of Missouri. In the event that either party moves the Chancery Court of Davidson County, Tennessee to reopen the case, we expect the Court would grant such motion and reopen the case. Further, the same customer has made a claim under the Partnership’s insurance policy. The insurer has denied the claim. However, in the event that the customer is successful in pursuing the claim, such action would negatively impact the Partnership because the Partnership may have certain reimbursement obligations it would owe the insurance company. If the case is reopened or the insurance claim by the customer is successful, we are currently unable to determine the exposure we may have in this matter, if any.

NOTE 14. FAIR VALUE MEASUREMENTS

The Partnership uses a valuation framework based upon inputs that market participants use in pricing certain assets and liabilities. These inputs are classified into two categories: observable inputs and unobservable inputs. Observable inputs represent market data obtained from independent sources. Unobservable inputs represent the Partnership's own market assumptions. Unobservable inputs are used only if observable inputs are unavailable or not reasonably available without undue cost and effort. The two types of inputs are further prioritized into the following hierarchy:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that reflect the entity's own assumptions and are not corroborated by market data.

Commodity derivative contracts, net	$	(412)	$	(207)

The Partnership is required to disclose estimated fair values for its financial instruments. Fair value estimates are set forth below for these financial instruments. The following methods and assumptions were used to estimate the fair value of each class of financial instrument:

•Accounts and other receivables, trade and other accounts payable, accrued interest payable, other accrued liabilities, income taxes payable and due from/to affiliates: The carrying amounts approximate fair value due to the short maturity and highly liquid nature of these instruments, and as such these have been excluded from the table below. There is negligible credit risk associated with these instruments.

•Current and non-current portion of long-term debt: The carrying amount of the revolving credit facility approximates fair value due to the debt having a variable interest rate and is in Level 2. The estimated fair value of the 2021 Notes, 2024 Notes, and 2025 Notes (collectively, the "Senior Notes") is considered Level 1, as the fair value is based on quoted market prices in active markets.

NOTE 15. CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The Partnership's operations are conducted by its operating subsidiaries as it has no independent assets or operations. Martin Operating Partnership L.P. (the "Operating Partnership"), the Partnership’s wholly-owned subsidiary, and the Partnership's other operating subsidiaries have issued in the past, and may issue in the future, unconditional guarantees of senior or subordinated debt securities of the Partnership. The guarantees that have been issued are full, irrevocable and unconditional and joint and several. In addition, the Operating Partnership may also issue senior or subordinated debt securities which, if issued, will be fully, irrevocably and unconditionally guaranteed by the Partnership. Substantially all of the Partnership's operating subsidiaries are subsidiary guarantors of its Senior Notes and any subsidiaries other than the subsidiary guarantors are minor.

	2021		2020		2021		2020
Provision for income taxes	$	935	$	790	$	1,157	$	1,137

The operations of a partnership are generally not subject to income taxes, except for Texas margin tax, because its income is taxed directly to its partners. MTI, a wholly owned subsidiary of the Partnership, is subject to income taxes due to its corporate structure (the "Taxable Subsidiary"). Total income tax expense of $874 and $590, related to the operation of the Taxable Subsidiary, for the three months ended June 30, 2021 and 2020, resulted in an effective income tax rate ("ETR") of 40.22% and (472.00)%, respectively. Total income tax expense of $977 and $937, related to the operation of the Taxable Subsidiary, for the six months ended June 30, 2021 and 2020, resulted in an ETR of 38.73% and 98.32%, respectively.

June 30, 2021

(Unaudited)

The increase in the effective income tax rate during the three months ended June 30, 2021 compared to the three months ended June 30, 2020 was primarily due to pretax income recorded for the three months ended June 30, 2021 compared to pretax losses recorded for the similar period in 2020. The decrease in the effective income tax rate during the six months ended June 30, 2021, compared to the six months ended June 30, 2020, was primarily due to a decrease in permanent differences in the current period. The increase in the provision for income taxes for the three and six months ended June 30, 2021, compared to similar periods in 2020, was primarily due to an increase in income before income taxes in the current period.

A current federal income tax expense (benefit) of $108 and $(307), related to the operation of the Taxable Subsidiary, was recorded for the three months ended June 30, 2021 and 2020, respectively. A current federal income tax expense (benefit) of $123 and $(174), related to the operation of the Taxable Subsidiary, was recorded for the six months ended June 30, 2021 and 2020, respectively. A current state income tax expense of $83 and $164, related to the operation of the Taxable Subsidiary, was recorded for the three months ended June 30, 2021 and 2020, respectively. A current state income tax expense of $96 and $93, related to the operation of the Taxable Subsidiary, was recorded for the six months ended June 30, 2021 and 2020, respectively.

With respect to MTI, income taxes are accounted for under the asset and liability method pursuant to the provisions of ASC 740 related to income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

A deferred tax expense related to the MTI temporary differences of $683 and $733 was recorded for the three months ended June 30, 2021 and 2020, respectively. A deferred tax expense related to the MTI temporary differences of $758 and $1,018 was recorded for the six months ended June 30, 2021 and 2020, respectively. A net deferred tax asset of $21,495 and $22,253, related to the cumulative book and tax temporary differences, existed at June 30, 2021 and December 31, 2020, respectively.

All income tax positions taken for all open years are more likely than not to be sustained based upon their technical merit under applicable tax laws.

NOTE 17. SUBSEQUENT EVENTS

We are a publicly traded limited partnership with a diverse set of operations focused primarily in the U.S. Gulf Coast region. Our four primary business lines include:

•Terminalling, processing, storage and packaging services for petroleum products and by-products including the refining of naphthenic crude oil;

•Land and marine transportation services for petroleum products and by-products, chemicals, and specialty products;

•Sulfur and sulfur-based products processing, manufacturing, marketing, and distribution; and

•NGL marketing, distribution, and transportation services.

The petroleum products and by-products we collect, transport, store and market are produced primarily by major and independent oil and gas companies who often turn to third parties, such as us, for the transportation and disposition of these products. In addition to these major and independent oil and gas companies, our primary customers include independent refiners, large chemical companies, and other wholesale purchasers of these products. We operate primarily in the U.S. Gulf Coast region. This region is a major hub for petroleum refining, natural gas gathering and processing, and support services for the exploration and production industry.

We were formed in 2002 by Martin Resource Management Corporation, a privately-held company whose initial predecessor was incorporated in 1951 as a supplier of products and services to drilling rig contractors. Since then, Martin Resource Management Corporation has expanded its operations through acquisitions and internal expansion initiatives as its management identified and capitalized on the needs of producers and purchasers of petroleum products and by-products and other bulk liquids. Martin Resource Management Corporation is an important supplier and customer of ours. As of June 30, 2021, Martin Resource Management Corporation owned 15.8% of our total outstanding common limited partner units. Furthermore, Martin Resource Management Corporation controls Martin Midstream GP LLC ("MMGP"), our general partner, by virtue of its 51% voting interest in MMGP Holdings, LLC ("Holdings"), the sole member of MMGP. MMGP owns a 2.0% general partner interest in us and all of our incentive distribution rights. Martin Resource Management Corporation directs our business operations through its ownership interests in and control of our general partner.

We entered into the Omnibus Agreement that governs, among other things, potential competition and indemnification obligations among the parties to the agreement, related party transactions, the provision of general administration and support services by Martin Resource Management Corporation and our use of certain of Martin Resource Management Corporation’s trade names and trademarks. Under the terms of the Omnibus Agreement, the employees of Martin Resource Management Corporation are responsible for conducting our business and operating our assets.

Martin Resource Management Corporation has operated our business since our inception in 2002. Martin Resource Management Corporation began operating our NGL business in the 1950s and our sulfur business in the 1960s. It began our land transportation business in the early 1980s and our marine transportation business in the late 1980s. It entered into our fertilizer and terminalling and storage businesses in the early 1990s.

Significant Recent Developments

Amendment to Revolving Credit Facility. On July 16, 2021, the Operating Partnership and the Partnership entered into a Twelfth Amendment to Third Amended and Restated Credit Agreement (the "Twelfth Amendment") with Royal Bank of Canada, as administrative agent and collateral agent for the lenders and as an L/C Issuer and a lender, and the other lenders party thereto, which amends the Third Amended and Restated Credit Agreement, dated as of March 28, 2013, as amended (the “Credit Agreement”).

Upon the closing of the Twelfth Amendment, the Credit Agreement was amended to, among other things:

•reduce the aggregate amount of commitments under the Credit Agreement from $300.0 million to $275.0 million;

•eliminate the Partnership’s ability to increase the commitments under the Credit Agreement without the requisite consent of the lenders;

•eliminate the requirement for a $25.0 million reduction in the commitments under the Credit Agreement if the Partnership receives $25.0 million or more in net cash proceeds from any asset sale;

•require the Operating Partnership to maintain a minimum Interest Coverage Ratio (as defined in the Credit Agreement) of 1.75:1.0 with respect to the fiscal quarter ended in June of 2021, 1.6:1.0 with respect to the fiscal quarter ending in September of 2021, 1.75:1.0 with respect to the fiscal quarter ending in December of 2021, 1.85:1.0 with respect to the fiscal quarters ending in March and June of 2022, and 2.0:1.0 with respect to each fiscal quarter thereafter;

•require the Operating Partnership to maintain a maximum Total Leverage Ratio (as defined in the Credit Agreement) of not more than 5.75:1.0 with respect to the fiscal quarters ending in June and September of 2021, 5.25:1.0 with respect to the fiscal quarter ending in December of 2021, and 5.0:1.0 with respect to each fiscal quarter thereafter; and

•require the Operating Partnership to maintain a maximum First Lien Leverage Ratio (as defined in the Credit Agreement) of not more than 2.25:1.0 with respect to each fiscal quarter ending in 2021, 1.75:1.0 with respect to each fiscal quarter ending in 2022, and 1.5:1.0 with respect to each fiscal quarter thereafter.

Winter Storm Uri. In February 2021, we experienced Winter Storm Uri ("Uri"), an unprecedented storm bringing extreme cold temperatures to Texas and the surrounding areas, which resulted in gulf coast refineries running at reduced rates or halting operations entirely. The majority of the impact we experienced was centered around our transportation and sulfur services segments where we saw reduced activity due to Uri's impact on Gulf Coast refinery utilization. Additionally, our Smackover Refinery was down approximately nine days due to Uri, during which time we began preparations for the previously scheduled turnaround in March of 2021. This allowed us to minimize the amount of downtime at the Smackover Refinery which was back in operation by March 9, 2021.

COVID-19. We continue to monitor the impacts of the COVID-19 pandemic on all aspects of our business. Travel restrictions and stay-at-home orders in place during much of 2020 that were implemented by governments in many regions and countries across the globe, including the U.S., have greatly impacted the demand for refined products resulting in a significant reduction in refinery utilization, which impacted our 2020 performance and continues to impact our marine transportation business in 2021.

Looking forward, we expect to continue to experience some adverse impacts of COVID-19 in our marine transportation segment but we believe that refinery utilization will continue to increase in the second half of 2021 as a result of widespread vaccinations, government stimulus, and a rebounding economy. This should ultimately improve refined product demand as people generally return to in-person work and resume travel. We expect this will positively impact our marine transportation business as demand for our services improves.

Overall, the extent to which the duration and severity of the pandemic impacts our business, results of operations, and financial condition will depend on future developments, which are highly uncertain and cannot be predicted at this time. Accordingly, it is possible that the impact of the pandemic, including the impact of variants of COVID-19, such as the Delta variant, could have a material adverse effect on the Partnership's results of operations, financial position and cash flows for the year ended December 31, 2021 including the recoverability of long-lived assets and goodwill, the valuation of inventory, and the amount of expected credit losses.

Management considered the impact of the pandemic on the assumptions and estimates used in the preparation of the financial statements. A sustained reduction in refinery demand and utilization could lead to future asset impairments as well as adversely affect access to capital and financing to be able to meet future obligations. Management also assessed the extent to which the current macroeconomic events brought about by the pandemic and significant declines in refined product demand impacted the valuation of expected credit losses on accounts receivable and certain inventory items or resulted in modifications

to any significant contracts. Ultimately the results of these assessments did not have a material impact on our results as of June 30, 2021.

Sale of Mega Lubricants. On December 22, 2020, we entered into an asset purchase and sale agreement to sell certain assets used in connection with our Mega Lubricants shore-based terminals business ("Mega Lubricants") to John W. Stone Oil Distributor, LLC ("Stone Oil") for $22.4 million. Mega Lubricants is engaged in the business of blending, manufacturing and delivering various marine application lubricants, sub-sea specialty fluids, and proprietary commercial and industrial products. The transaction closed on December 22, 2020. The proceeds from the transaction were used to reduce outstanding borrowings under our revolving credit facility.

Subsequent Events

Quarterly Distribution. On July 22, 2021, we declared a quarterly cash distribution of $0.005 per common unit for the second quarter of 2021, or $0.020 per common unit on an annualized basis, which will be paid on August 13, 2021 to unitholders of record as of August 6, 2021.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on the historical consolidated and condensed financial statements included elsewhere herein. We prepared these financial statements in conformity with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. We routinely evaluate these estimates, utilizing historical experience, consultation with experts and other methods we consider reasonable in the particular circumstances. Our results may differ from these estimates, and any effects on our business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. Changes in these estimates could materially affect our financial position, results of operations or cash flows. See the "Critical Accounting Policies and Estimates" section in "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 2, "Significant Accounting Policies" in Notes to Consolidated Financial Statements included within our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on March 3, 2021.

Approval and Review of Related Party Transactions

If we contemplate entering into a transaction, other than a routine or in the ordinary course of business transaction, in which a related person will have a direct or indirect material interest, the proposed transaction is submitted for consideration to the board of directors of our general partner or to our management, as appropriate. If the board of directors of our general partner is involved in the approval process, it determines whether to refer the matter to the Conflicts Committee of our general partner's board of directors, as constituted under our limited partnership agreement. If a matter is referred to the Conflicts Committee, it obtains information regarding the proposed transaction from management and determines whether to engage independent legal counsel or an independent financial advisor to advise the members of the committee regarding the transaction. If the Conflicts Committee retains such counsel or financial advisor, it considers such advice and, in the case of a financial advisor, such advisor’s opinion as to whether the transaction is fair and reasonable to us and to our unitholders.

How We Evaluate Our Operations

Our management uses a variety of financial and operational measurements other than our financial statements prepared in accordance with U.S. GAAP to analyze our performance. These include: (1) net income before interest expense, income tax expense, and depreciation and amortization ("EBITDA"), (2) adjusted EBITDA, (3) distributable cash flow and (4) adjusted free cash flow. Our management views these measures as important performance measures of core profitability for our operations and the ability to generate and distribute cash flow, and as key components of our internal financial reporting. We believe investors benefit from having access to the same financial measures that our management uses.

EBITDA and Adjusted EBITDA. We define Adjusted EBITDA as EBITDA before unit-based compensation expenses, gains and losses on the disposition of property, plant and equipment, impairment and other similar non-cash adjustments. Certain items excluded from EBITDA and adjusted EBITDA are significant components in understanding and assessing an entity's financial performance, such as cost of capital and historical costs of depreciable assets. We have included information concerning EBITDA and adjusted EBITDA because it provides investors and management with additional information to better understand the following: financial performance of our assets without regard to financing methods, capital structure or historical cost basis; our operating performance and return on capital as compared to those of other similarly situated entities; and the viability of acquisitions and capital expenditure projects. Our method of computing adjusted EBITDA may not be the same method used to compute similar measures reported by other entities. The economic substance behind our use of adjusted EBITDA is to measure the ability of our assets to generate cash sufficient to pay interest costs, support our indebtedness and make distributions to our unitholders.

Distributable Cash Flow. We define Distributable Cash Flow as Adjusted EBITDA less cash paid for interest, cash paid for income taxes, maintenance capital expenditures, and plant turnaround costs. Distributable cash flow is a significant performance measure used by our management and by external users of our financial statements, such as investors, commercial banks and research analysts, to compare basic cash flows generated by us to the cash distributions it expects to pay unitholders. Distributable cash flow is also an important financial measure for our unitholders since it serves as an indicator of our success in providing a cash return on investment. Specifically, this financial measure indicates to investors whether or not we are generating cash flow at a level that can sustain or support an increase in our quarterly distribution rates. Distributable cash flow is also a quantitative standard used throughout the investment community with respect to publicly-traded partnerships because the value of a unit of such an entity is generally determined by the unit's yield, which in turn is based on the amount of cash distributions the entity pays to a unitholder.

Adjusted Free Cash Flow. Adjusted free cash flow is defined as distributable cash flow less growth capital expenditures and principle payments under finance lease obligations. Adjusted free cash flow is a significant performance measure used by our management and by external users of our financial statements and represents how much cash flow a business generates during a specified time period after accounting for all capital expenditures, including expenditures for growth and maintenance capital projects. We believe that adjusted free cash flow is important to investors, lenders, commercial banks and research analysts since it reflects the amount of cash available for reducing debt, investing in additional capital projects, paying distributions, and similar matters. Our calculation of adjusted free cash flow may or may not be comparable to similarly titled measures used by other entities.

EBITDA, adjusted EBITDA, distributable cash flow and adjusted free cash flow should not be considered alternatives to, or more meaningful than, net income, cash flows from operating activities, or any other measure presented in accordance with U.S. GAAP. Our method of computing these measures may not be the same method used to compute similar measures reported by other entities.

Reconciliation of Non-GAAP Financial Measures

The following table reconciles the non-GAAP financial measurements used by management to our most directly comparable GAAP measures for the three and six months ended June 30, 2021 and 2020.

Results of Operations

The results of operations for the three and six months ended June 30, 2021 and 2020 have been derived from our consolidated and condensed financial statements.

We evaluate segment performance on the basis of operating income, which is derived by subtracting cost of products sold, operating expenses, selling, general and administrative expenses, and depreciation and amortization expense from revenues. The following table sets forth our operating revenues and operating income by segment for the three and six months ended June 30, 2021 and 2020. The results of operations for these interim periods are not necessarily indicative of the results of operations which might be expected for the entire year.

Our consolidated and condensed results of operations are presented on a comparative basis below. There are certain items of income and expense which we do not allocate on a segment basis. These items, including interest expense and indirect selling, general and administrative expenses, are discussed following the comparative discussion of our results within each segment.

Services revenues. Services revenues decreased $1.1 million, of which $1.1 million was primarily a result of the disposition of the consigned lube business as part of the Mega Lubricants sale as well as decreases in space rent and throughput revenue of $0.2 million at our shore-based terminals. In addition, revenue at the Smackover refinery decreased $0.3 million primarily due to the expiration of the capital recovery fee . Offsetting these decreases are increases at our specialty terminals related to throughput revenue of $0.5 million.

Products revenues. The disposition of our Mega Lubricants business resulted in a $5.2 million decrease in product revenues at our shore-based terminals. Offsetting this reduction, a 14% increase in average sales price combined with 9% higher sales volumes at our blending and packaging facilities resulted in a $4.9 million increase to products revenues.

Cost of products sold. The disposition of our Mega Lubricants business resulted in a $6.0 million decrease in cost of products sold at our shore-based terminals.

Indirect selling, general and administrative expenses decreased for the three and six months ended June 30, 2021 compared to the three and six months ended June 30, 2020 primarily due to a decrease in the indirect expenses allocated from Martin Resource Management Corporation.

Martin Resource Management Corporation allocates to us a portion of its indirect selling, general and administrative expenses for services such as accounting, legal, treasury, clerical, billing, information technology, administration of insurance, engineering, general office expense and employee benefit plans and other general corporate overhead functions we share with Martin Resource Management Corporation retained businesses. This allocation is based on the percentage of time spent by Martin Resource Management Corporation personnel that provide such centralized services. GAAP also permits other methods for allocation of these expenses, such as basing the allocation on the percentage of revenues contributed by a segment. The allocation of these expenses between Martin Resource Management Corporation and us is subject to a number of judgments and estimates, regardless of the method used. We can provide no assurances that our method of allocation, in the past or in the future, is or will

be the most accurate or appropriate method of allocation for these expenses. Other methods could result in a higher allocation of selling, general and administrative expense to us, which would reduce our net income.

Under the Omnibus Agreement, we are required to reimburse Martin Resource Management Corporation for indirect general and administrative and corporate overhead expenses. The Conflicts Committee of our general partner approved the following reimbursement amounts during the three and six months ended June 30, 2021 and 2020:

The amounts reflected above represent our allocable share of such expenses. The Conflicts Committee will review and approve future adjustments in the reimbursement amount for indirect expenses, if any, annually.

Liquidity and Capital Resources

General

Our primary sources of liquidity to meet operating expenses, service our indebtedness, fund capital expenditures and pay distributions to our unitholders have historically been cash flows generated by our operations, borrowings under our revolving credit facility and access to debt and equity capital markets, both public and private. Set forth below is a description of our cash flows for the periods indicated.

Cash Flows - Six Months Ended June 30, 2021 Compared to Six Months Ended June 30, 2020

The following table details the cash flow changes between the six months ended June 30, 2021 and 2020:

Description of Our Indebtedness

Revolving Credit Facility

At June 30, 2021, we maintained a $300.0 million revolving credit facility that matures on August 31, 2023. As of June 30, 2021, we had $179.5 million outstanding under the revolving credit facility and $26.7 million of outstanding irrevocable letters of credit, leaving a maximum available to be borrowed under our credit facility for future revolving credit borrowings and letters of credit of $93.8 million. After giving effect to our then current borrowings, letters of credit (to the extent drawn), and the financial covenants contained in our revolving credit facility, we had the ability to borrow approximately $40.6 million in additional amounts thereunder as of June 30, 2021. As part of the amendment to our credit facility that closed on July 16, 2021, the lenders’ commitments were reduced from $300.0 million to $275.0 million. As a result of the financial covenants in the revolving credit facility, such reduction of the lenders’ commitments would not have impacted our available liquidity under the revolving credit facility at June 30, 2021, nor did it reduce the currently foreseeable amount that we can borrow under the revolving credit facility. See “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Significant Recent Developments – Amendment to Revolving Credit Facility” for more information regarding this amendment.

The revolving credit facility is used for ongoing working capital needs and general partnership purposes, and to finance permitted investments, acquisitions and capital expenditures. During the six months ended June 30, 2021, the level of outstanding draws on our credit facility has ranged from a low of $148.0 million to a high of $201.0 million.

The credit facility is guaranteed by substantially all of our subsidiaries. Obligations under the credit facility are secured by first priority liens on substantially all of our assets and those of the guarantors, including, without limitation, inventory, accounts receivable, bank accounts, marine vessels, equipment, fixed assets and the interests in our subsidiaries.

We may prepay all amounts outstanding under the credit facility at any time without premium or penalty (other than customary LIBOR breakage costs), subject to certain notice requirements. The credit facility requires mandatory prepayments of amounts outstanding thereunder with excess cash that exceeds $25.0 million and the net proceeds of certain asset sales, equity issuances and debt incurrences.

Indebtedness under the credit facility bears interest at our option at the Eurodollar Rate (LIBOR), with a floor for LIBOR of 1%, plus an applicable margin, or the Base Rate (the highest of the Federal Funds Rate plus 0.50%, the 30-day Eurodollar Rate plus 1.0%, or the administrative agent’s prime rate) plus an applicable margin. We pay a per annum fee on all letters of credit issued under the credit facility, and we pay a commitment fee per annum on the unused revolving credit commitments under the credit facility. The letter of credit fee, the commitment fee and the applicable margins for our interest rate vary quarterly based on our Total Leverage Ratio (as defined in the credit facility, being generally computed as the ratio of total funded debt to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges) and are as follows as of June 30, 2021:


Leverage Ratio	Base Rate Loans		Eurodollar Rate Loans		Letters of Credit
Less than 3.00 to 1.00	1.75	%	2.75	%	2.75	%
Greater than or equal to 3.00 to 1.00 and less than 3.50 to 1.00	2.00	%	3.00	%	3.00	%
Greater than or equal to 3.50 to 1.00 and less than 4.00 to 1.00	2.25	%	3.25	%	3.25	%
Greater than or equal to 4.00 to 1.00 and less than 4.50 to 1.00	2.50	%	3.50	%	3.50	%
Greater than or equal to 4.50 to 1.00 and less than 5.00 to 1.00	2.75	%	3.75	%	3.75	%
Greater than or equal to 5.00 to 1.00	3.00	%	4.00	%	4.00	%

The applicable margin for LIBOR borrowings at June 30, 2021 is 4.00%, with a 1% floor for LIBOR.

The credit facility includes financial covenants that are tested on a quarterly basis, based on the rolling four quarter period that ends on the last day of each fiscal quarter.

In addition, the credit facility contains various covenants, which, among other things, limit our and our subsidiaries’ ability to: (i) grant or assume liens; (ii) make investments (including investments in our joint ventures) and acquisitions; (iii) enter into certain types of hedging agreements; (iv) incur or assume indebtedness; (v) sell, transfer, assign or convey assets; (vi) repurchase our equity, make distributions (including a limit on our ability to make quarterly distributions to unitholders in excess of $0.005 per unit unless our Total Leverage Ratio (as defined in the credit facility) is below 3.75:1:00 and certain other restricted payments; (vii) change the nature of our business; (viii) engage in transactions with affiliates; (ix) enter into certain burdensome agreements; (x) make certain amendments to the Omnibus Agreement and our material agreements; and (xi) permit our joint ventures to incur indebtedness or grant certain liens.

The credit facility contains customary events of default, including, without limitation: (i) failure to pay any principal, interest, fees, expenses or other amounts when due; (ii) failure to meet the quarterly financial covenants; (iii) failure to observe any other agreement, obligation, or covenant in the credit facility or any related loan document, subject to cure periods for certain failures; (iv) the failure of any representation or warranty to be materially true and correct when made; (v) our, or any of our subsidiaries’ default under other indebtedness that exceeds a threshold amount; (vi) bankruptcy or other insolvency events involving us or any of our subsidiaries; (vii) judgments against us or any of our subsidiaries, in excess of a threshold amount; (viii) certain ERISA events involving us or any of our subsidiaries, in excess of a threshold amount; (ix) a change in control (as defined in the credit facility); and (x) the invalidity of any of the loan documents or the failure of any of the collateral documents to create a lien on the collateral.

The credit facility also contains certain default provisions relating to Martin Resource Management Corporation. If Martin Resource Management Corporation no longer controls our general partner, the lenders under the credit facility may declare all amounts outstanding thereunder immediately due and payable. In addition, an event of default by Martin Resource Management Corporation under its credit facility could independently result in an event of default under our credit facility if it is deemed to have a material adverse effect on us.

If an event of default relating to bankruptcy or other insolvency events occurs with respect to us or any of our subsidiaries, all indebtedness under our credit facility will immediately become due and payable. If any other event of default exists under our credit facility, the lenders may terminate their commitments to lend us money, accelerate the maturity of the indebtedness outstanding under the credit facility and exercise other rights and remedies. In addition, if any event of default exists under our credit facility, the lenders may commence foreclosure or other actions against the collateral.

Senior Secured Notes due 2025 and 2024

For a description of our 11.50% senior secured second lien notes due 2025 and 10.00% senior secured 1.5 lien notes due 2024, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Description of Our Long-Term Debt" in our Annual Report on Form 10-K for the year ended December 31, 2020.

Capital Resources and Liquidity

Historically, we have generally satisfied our working capital requirements and funded our debt service obligations and capital expenditures with cash generated from operations and borrowings under our revolving credit facility.

On June 30, 2021, we had cash and cash equivalents of $0.7 million and available borrowing capacity of $93.8 million under our revolving credit facility with $179.5 million of borrowings outstanding. After giving effect to our current borrowings, outstanding letters of credit and the financial covenants contained in our revolving credit facility, we had the ability to borrow approximately $40.6 million in additional amounts thereunder as of June 30, 2021. Our revolving credit facility matures on August 31, 2023.

We expect that our primary sources of liquidity to meet operating expenses, service our indebtedness, pay distributions to our unitholders and fund capital expenditures will be provided by cash flows generated by our operations, borrowings under our revolving credit facility and access to the debt and equity capital markets. Our ability to generate cash from operations will depend upon our future operating performance, which is subject to certain risks. For a discussion of such risks, please read "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2020, filed with the SEC on March 3, 2021. In addition, due to the covenants in our revolving credit facility, our financial and operating performance impacts the amount we are permitted to borrow under that facility.

We are in compliance with all debt covenants as of June 30, 2021 and expect to be in compliance for the next twelve months.

Interest Rate Risk

We are subject to interest rate risk on our credit facility due to the variable interest rate and may enter into interest rate swaps to reduce this variable rate risk.

Seasonality

A substantial portion of our revenues is dependent on sales prices of products, particularly NGLs and fertilizers, which fluctuate in part based on winter and spring weather conditions. The demand for NGLs is strongest during the winter heating season and refinery blending season. The demand for fertilizers is strongest during the early spring planting season. However, our Terminalling and Storage and Transportation business segments and the molten sulfur business are typically not impacted by seasonal fluctuations and a significant portion of our net income is derived from our Terminalling and Storage, Sulfur Services and Transportation business segments. Further, extraordinary weather events, such as hurricanes, have in the past, and could in the future, impact our Terminalling and Storage, Sulfur Services, and Transportation business segments.

Impact of Inflation

Inflation did not have a material impact on our results of operations for the six months ended June 30, 2021 or 2020. Although the impact of inflation has been insignificant in recent years, it is still a factor in the U.S. economy and may increase the cost to acquire or replace property, plant and equipment. It may also increase the costs of labor and supplies. In the future, increasing energy prices could adversely affect our results of operations. Diesel fuel, natural gas, chemicals and other supplies are recorded in operating expenses. An increase in price of these products would increase our operating expenses which could adversely affect net income. We cannot provide assurance that we will be able to pass along increased operating expenses to our customers.

Environmental Matters

Our operations are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which these operations are conducted. We incurred no material environmental costs, liabilities or expenditures to mitigate or eliminate environmental contamination during the six months ended June 30, 2021 or 2020.


Item 3.			Quantitative and Qualitative Disclosures about Market Risk

The Partnership is exposed to commodity risk and interest rate risk in its normal business activities. The following disclosures about market risk provide an update to, and should be read in conjunction with, “Item 7A. Quantitative and Qualitative Disclosures about Market Risk” set forth in our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on March 3, 2021.

Commodity Risk. The Partnership from time to time uses derivatives to manage the risk of commodity price fluctuation. Commodity risk is the adverse effect on the value of a liability or future purchase that results from a change in commodity price. We have established a hedging policy and monitor and manage the commodity market risk associated with potential commodity risk exposure. In addition, we focus on utilizing counterparties for these transactions whose financial condition is appropriate for the credit risk involved in each specific transaction.

We have entered into hedging transactions as of June 30, 2021 to protect a portion of our commodity price risk exposure. These hedging arrangements are in the form of swaps and options for NGLs. We have instruments totaling a gross notional quantity of 390,000 barrels settling during the period from July 31, 2021 through December 31, 2021. These instruments settle against the applicable pricing source for each grade and location. These instruments are recorded on our Consolidated and Condensed Balance Sheets at June 30, 2021 in "Fair value of derivatives" as a current liability of $0.4 million. Based on the current net notional volume hedged as of June 30, 2021, a $0.10 change in the expected settlement price of these contracts would result in an impact to our net income of approximately $1.6 million.

Interest Rate Risk. We are exposed to changes in interest rates as a result of our credit facility, which had a weighted-average interest rate of 5.00% as of June 30, 2021. Based on the amount of unhedged floating rate debt owed by us on June 30, 2021, the impact of a 100 basis point increase in interest rates on this amount of debt would result in an increase in interest expense and a corresponding decrease in net income of approximately $1.8 million annually.

We are not exposed to changes in interest rates with respect to our 2024 Notes and 2025 Notes as these obligations are fixed rate. Based on the quoted prices for identical liabilities in markets that are not active at June 30, 2021, the estimated fair value of the 2024 Notes and 2025 Notes was $55.3 million and $303.9 million, respectively. Market risk is estimated as the potential decrease in fair value of our long-term debt resulting from a hypothetical increase of a 100 basis point increase in interest rates. Such an increase in interest rates at June 30, 2021, would result in a $0.1 million decrease in the fair value of our 2024 Notes and a $8.9 million decrease in the fair value of our 2025 Notes.


Item 4.			Controls and Procedures

Evaluation of disclosure controls and procedures. In accordance with Rules 13a-15 and 15d-15 of the Exchange Act, we, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer of our general partner, carried out an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer of our general partner concluded that our disclosure controls and procedures were effective, as of the end of the period covered by this report, to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

There were no changes in our internal controls over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II - OTHER INFORMATION


Item 1.			Legal Proceedings

From time to time, we are subject to certain legal proceedings, claims and disputes that arise in the ordinary course of our business. Although we cannot predict the outcomes of these legal proceedings, we do not believe these actions, in the aggregate, will have a material adverse impact on our financial position, results of operations or liquidity. Information regarding legal proceedings is set forth in Note 13 in Part I of this Form 10-Q.


Item 1A.			Risk Factors

There have been no material changes to the Partnership's risk factors since our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on March 3, 2021.


Item 5.			Other Information

Disclosure Pursuant to Item 5.02 of Form 8-K – Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers. On July 21, 2021, the board of directors of the general partner of the Partnership and the Compensation Committee approved the Martin Midstream Partners L.P. 2021 Phantom Unit Plan (the “Plan”), effective as of the same date. The Plan permits the awards of phantom units and phantom unit appreciation rights to any employee or non-employee director of the Partnership, including its executive officers. The awards may be time-based or performance-based and will be paid, if at all, in cash.

The award of a phantom unit entitles the participant to a cash payment equal to the value of the phantom unit on the vesting date or dates, which value is the fair market value of a common unit of the Partnership (a “Unit”) on such vesting date or dates. The award of a phantom unit appreciation right entitles the recipient to a cash payment equal to the difference between the value of a phantom unit on the vesting date or dates in excess of the value assigned by the Compensation Committee to the phantom unit as of the grant date. Phantom units and phantom unit appreciation rights granted to participants do not confer upon participants any right to a Unit.

On July 21, 2021, the Compensation Committee approved forms of time-based award agreements for phantom units and phantom unit appreciation rights, both of which awards vest in full on the third anniversary of the grant date. The grant date value of a phantom unit under a phantom unit appreciate right award is equal to the average of the closing price for a Unit during the 20 trading days immediately preceding the grant date of the award.

Generally, vesting of an award is subject to a participant remaining continuously employed with the Partnership through the vesting date. However, if prior to the vesting date (i) a participant is terminated without cause (as defined in the award agreement) or terminates employment after the participant has attained age 65 and ten years of employment (“retirement-eligible”), a prorated portion of the award will vest and be paid in cash no later than the 30th day following such termination date (subject to a six-month delay in payment for certain retirement-eligible participants) or (ii) there is a change in control of the Partnership (as defined in the Plan), the award will vest in full and be paid in cash no later than the 30th day following the date of the change of control; provided, however, the participant has been in continuous employment through the termination or change in control date, as applicable.

On July 21, 2021, 620,000 phantom units and 1,245,000 phantom unit appreciation rights were granted to employees of the general partner and its affiliates who perform services for the Partnership.

The foregoing summary of the Plan is qualified in its entirety by reference to the complete text of the Plan, the form of award agreement for phantom units and the form of award agreement for phantom unit appreciation rights, copies of which are filed as Exhibits 10.1, 10.2 and 10.3 to this Form 10-Q.
