Except where the context otherwise requires, references in this Form 10-K to (i) “Ecolab,” “Company,” “we” and “our” are to Ecolab Inc. and its subsidiaries, collectively; (ii) “Nalco” are to Nalco Company LLC, a wholly-owned subsidiary of the Company; (iii) “Nalco transaction” and “Nalco merger” are to the merger of Ecolab and Nalco Holding Company completed in December 2011; (iv) “Purolite” are to Purolite LLC, a wholly-owned subsidiary of the Company and its subsidiaries, collectively; and (v) “Purolite transaction” are to the Company’s acquisition of the shares of the subsidiaries and certain other affiliated entities of Purolite Corporation and substantially all of the assets of Purolite Corporation used or held for use in connection with its filtration and purification resins business in December 2021.

​

​

Item 1. Business.

​

General Development of Business.

​

Ecolab was incorporated as a Delaware corporation in 1924. Our fiscal year is the calendar year ending December 31. International subsidiaries are included in the consolidated financial statements on the basis of their U.S. GAAP (accounting principles generally accepted in the United States of America) November 30 fiscal year ends to facilitate the timely inclusion of such entities in our consolidated financial reporting.

​

In June 2020, we completed the separation of our Upstream Energy business (the “ChampionX business”) in a Reverse Morris Trust transaction (the “Transaction”) through the split-off of ChampionX Holding Inc. (“ChampionX”), formed by Ecolab as a wholly owned subsidiary to hold the ChampionX business, followed immediately by the merger (the “Merger”) of ChampionX with a wholly owned subsidiary of ChampionX Corporation (f/k/a Apergy Corporation, “Apergy”).

​

As discussed in Note 5 Discontinued Operations, the ChampionX business met the criteria to be reported as discontinued operations in 2020 because the separation of ChampionX was a strategic shift in business that had a major effect on our operations and financial results. Therefore, we reported the historical results of ChampionX, including the results of operations and cash flows as discontinued operations, and related assets and liabilities were retrospectively reclassified for all periods presented herein. Unless otherwise noted, the accompanying financial information has been revised to reflect the effect of the separation of ChampionX and prior year balances have been revised accordingly to reflect continuing operations only.

​

On December 1, 2021, we acquired Purolite for total consideration of $3.7 billion in cash, net of cash acquired. Purolite is a leading and fast-growing global provider of high-end ion exchange resins for the separation and purification of solutions that is highly complementary to our current offering and critical to safe, high quality drug production and biopharma product purification in the life sciences industries. It also provides purification and separation solutions for critical industrial markets like microelectronics, nuclear power and food and beverage. Headquartered in King of Prussia, Pennsylvania, Purolite operates in more than 30 countries. Purolite is reported within our Life Sciences operating segment.

​

​

Additional Information

​

International Operations

​

We directly operate in approximately 100 countries outside of the United States through wholly-owned subsidiaries or, in some cases, through a joint venture with a local partner. In certain countries, selected products are sold by our export operations to distributors, agents or licensees, although the volume of those sales is not significant in terms of our overall revenues. In general, our businesses conducted outside the United States are similar to those conducted in the United States.

​

Our business operations outside the United States are subject to the usual risks of foreign operations, including possible changes in trade and foreign investment laws, international business laws and regulations, tax laws, currency exchange rates and economic and political conditions. The profitability of our international operations is generally lower than the profitability of our businesses in the United States, due to (i) the additional cost of operating in numerous and diverse foreign jurisdictions with varying laws and regulations, (ii) higher costs of importing certain raw materials and finished goods in some regions, (iii) the smaller scale of international operations where certain operating locations are smaller in size, and (iv) the additional reliance on distributors and agents in certain countries which can negatively impact our margins. Proportionately larger investments in sales and technical support are also necessary in certain geographies in order to facilitate the growth of our international operations.

​

Table of Contents

Competition

​

In general, the markets in which the businesses in our Global Industrial reportable segment compete are led by a few large companies, with the rest of the market served by smaller entities focusing on more limited geographic regions or a smaller subset of products and services. Our businesses in this segment compete on the basis of their demonstrated value, technical expertise, innovation, digital technology, chemical formulations, global customer support, detection equipment, monitoring capabilities, and dosing and metering equipment. Through the combination of our digitally enabled end-to-end water management and hygiene solutions, data-driven insights and personalized service, our Global Industrial businesses deliver outcomes that help our customers optimize water and energy use, improve productivity, advance food safety, and achieve sustainability and net zero goals, while optimizing total cost of operations.

​

The businesses in our Global Institutional & Specialty reportable segment and Other have two significant classes of competitors. First, we compete with a small number of large companies selling directly or through distributors on a national or international scale. Second, we have numerous smaller regional or local competitors which focus on more limited geographies, product lines and/or end-use customer segments. We believe we compete principally by providing superior value, premium customer support, training, service, and innovative and differentiated products to help our customers protect their brand reputation and improve their operational efficiency.

​

Within the Global Healthcare & Life Sciences reportable segment, the Healthcare business competes geographically with companies primarily focused on a smaller range of product categories, with few globally scaled competitors. The Life Sciences business competes in the European market versus several mid-size and regional competitors and competes against two large and other mid-size or regional competitors in North America. Outside of North America and Europe competitors are much more fragmented and do not offer the same level of service or coverage as Ecolab. Our businesses in this segment compete by enabling our customers success through improved hygiene, digitally enabled programs in operating room and patient room space as well as a tailored approach to delivering key inputs that directly impact our customers patients globally.

​

Sales

​

Our products, systems and services are primarily marketed in domestic and international markets by our Company-trained direct field sales personnel who also advise and assist our customers in the proper and most efficient use of the products and systems in order to meet a full range of cleaning and sanitation, water treatment and process chemistry needs. Independent, third-party distributors and, to a lesser extent, sales agents, are utilized in several markets, as described in the segment descriptions found above.

​

Customers and Classes of Products

​

We believe our business is not materially dependent upon a single customer. Additionally, although we have a diverse customer base and no customer or distributor constituted 10 percent or more of our consolidated revenues in 2022, 2021 or 2020, we do have customers and independent third-party distributors, the loss of which could have a material adverse effect on results of operations for the affected earnings periods; however, we consider it unlikely that such an event would have a material adverse impact on our financial position. No material part of our business is subject to renegotiation or termination at the election of a governmental unit.

​

We sold one class of products within the Global Institutional & Specialty reportable segment which comprised 10% or more of consolidated net sales in the last three years. Sales of warewashing products were approximately 12%, 10%, and 11% of consolidated net sales in 2022, 2021 and 2020, respectively.

​

Human Capital

​

As of December 31, 2022, Ecolab employed approximately 47,000 employees, including approximately 26,000 sales and service and 1,100 research, development, and engineering employees. Approximately 41% of the employees are employed in North America, 21% in Europe, 7% in Asia Pacific, 17% in Latin America, 6% in India, Middle East and Africa, and 8% in Greater China.

​

We are committed to developing a culture that is diverse, equitable, inclusive, and fully leverages our employees’ talents as we work together to serve the needs of our customers. We believe in providing comprehensive training and career development opportunities and in compensating and rewarding our employees equitably. Our commitment to the safety of our employees, contractors and customers is evident in all we do, from the way we operate, to the products we develop and to the customers we serve. In addition, we are committed to promoting the health and well-being of our employees, our customers, and their customers by contributing to programs and initiatives that enhance the quality of life in the communities where they work and live. In support of these overall objectives, key areas of focus include:

​

Diversity, Equity, and Inclusion: We have a long-standing belief that a diverse, equitable, and inclusive workforce is a critical foundation for the shared success of our employees, our company, our customers, and our communities. To build that strong foundation, we have worked to embed diversity and inclusion throughout all people processes, including recruitment, promotional practices, training and development, and total rewards. To help guide our work and ensure a broad commitment to progress, Ecolab utilizes a Diversity Council made up of senior leaders throughout our company and chaired by our CEO. We review key metrics and practices, including diverse representation, hiring practices, and retention with the Council and with senior executives and business leads monthly. We set diversity goals at or above market availability and utilize diverse slates for all hiring activity.

​

We have a vibrant and growing community of Employee Resource Groups (ERGs) to help employees connect with colleagues, take part in career and leadership development experiences, and provide important insights in support of advancing our work in diversity, equity, and inclusion. These employee-led ERGs create community and focus across several dimensions of diversity, including gender, race/ethnicity, gender identity, sexual orientation, ability/disability, military service and more. All employees are welcome and encouraged to join, participate or become leaders within any of our 12 ERGs.

​

Employee Training and Development: At our core, Ecolab’s growth is rooted in decades of science, learning and innovation. We have ambitious solution-oriented teams and we continually look for ways to help our employees learn and grow. Beyond rigorous technical, functional, and business-specific training courses, our Global Corporate Flagship Development Programs are designed to deepen leadership capability and prepare successors for key leadership roles.

​

Safety, Health and Wellness: At Ecolab, the safety of our employees and contractors is a top priority and is embedded into our company values. Our safety goals are simple: zero accidents, zero injuries and zero violations. We communicate that this is a collective goal all employees commit to, own, and deliver on every day. Our leadership teams and a network of Safety, Health and Environment professionals around the world support employees with robust safety programs, processes, and platforms. Understanding underlying and potential risks is a critical component to improving safety outcomes. Our Global Safety Dashboard tracks our performance on a range of leading and lagging safety indicators and helps us measure the effectiveness of our safety programs.

​

Additionally, a Be Well Program is available to U.S. employees and their families to empower, educate and support their personal journey to overall well-being by making positive lifestyle choices while creating a culture of wellness throughout Ecolab. Over the last few years, we’ve expanded our offerings to include comprehensive child and elder caregiver resources to help employees balance the demands of work and personal responsibilities. To ensure the safety of our employees amidst an ongoing COVID-19 pandemic environment, we follow CDC and local guidance. We’ve continued to help our global employees garner access to vaccines and COVID-19 testing, have provided the option for employees who can do their work remotely to work from home on a hybrid schedule, and have implemented additional safety measures for our employees working in the field and in our plant and warehouse locations.

Patents and Trademarks

​

We own and license a number of patents, trademarks and other intellectual property, including intellectual property from our recent acquisition of Purolite. While we have an active program to protect our intellectual property by filing for patents or trademarks and pursuing legal action, when appropriate, to prevent infringement, except for the items listed below, we do not believe our overall business is materially dependent on any individual patent or trademark.

​

​

​

Seasonality

​

We experience variability in our quarterly operating results due to seasonal sales volume and business mix fluctuations in our operating segments. Part II, Item 8, Note 20, entitled “Quarterly Financial Data” of this Form 10-K is incorporated herein by reference.

​

Investments in Equipment

​

We have invested, and plan to continue to invest, in process control and monitoring equipment consisting primarily of systems used by customers to dispense our products as well as to monitor water systems. The investment in such equipment is discussed under the heading "Investing Activities" in Management's Discussion and Analysis of Financial Condition and Results of Operations of this Form 10-K.

Manufacturing and Distribution

​

We manufacture most of our products and related equipment in Company-operated manufacturing facilities. Some products are also produced for us by third-party contract manufacturers. Other products and equipment are purchased from third-party suppliers. Additional information on product/equipment sourcing is found in the segment discussions above and additional information on our manufacturing facilities is located under Part I, Item 2. “Properties,” of this Form 10-K.

​

Deliveries to customers are made from our manufacturing plants and a network of distribution centers and third-party logistics service providers. We use common carriers, our own delivery vehicles, and distributors for transport. Additional information on our plant and distribution facilities is located under Part I, Item 2. “Properties,” of this Form 10-K.

​

Raw Materials

​

Raw materials purchased for use in manufacturing our products are inorganic chemicals, including alkalis, acids, biocides, phosphonates, phosphorous materials, silicates and salts; and organic chemicals, including acids, alcohols, amines, fatty acids, surfactants, solvents, monomers and polymers. Healthcare purchases plastic films and parts to manufacture medical devices that serve the surgical and infection prevention markets. Pesticides used by Pest Elimination are purchased as finished products under contract or purchase order from the producers or their distributors. We also purchase packaging materials for our manufactured products and components for our specialized cleaning equipment and systems. We purchase more than 10,000 raw materials, with the largest single raw material representing approximately four percent of raw material purchases. Our raw materials, with the exception of a few specialized chemicals which we manufacture, are generally purchased on an annual contract basis and are ordinarily available in adequate quantities from a diverse group of suppliers globally. We have encountered supply chain disruptions with impacts of the COVID-19 pandemic, war in Ukraine and the overall energy crisis (mainly in Europe). These events have impacted the availability and cost of many raw materials. When practical, global sourcing is used so that purchasing or production locations can be shifted to control product costs.

​

Research and Development

​

Our research and development program consists principally of developing and validating the performance of new products, processes, techniques and equipment, improving the efficiency of those already existing, improving service program content, evaluating the environmental compatibility of products and technical support. Key disciplines include analytical and formulation chemistry, microbiology, data science and predictive analytics, process and packaging engineering, digital and remote monitoring engineering and product dispensing technology. Substantially all of our principal products have been developed by our research, development and engineering personnel.

​

We believe continued research and development activities are critical to maintaining our leadership position within the industry and will provide us with a competitive advantage as we seek additional business with new and existing customers.

​

Joint Ventures

​

Over time, we have entered into partnerships or joint ventures in order to meet local ownership requirements, to achieve quicker operational scale, to expand our ability to provide our customers a more fully integrated offering or to provide other benefits to our business or customers. During 2022, the impact on our consolidated net income of our joint ventures, in the aggregate, was approximately three percent. We will continue to evaluate the potential for partnerships and joint ventures that can assist us in increasing our geographic, technological and product reach.

​

Environmental and Regulatory Considerations

​

Our businesses are subject to various legislative enactments and regulations relating to the protection of the environment and public health. While we cooperate with governmental authorities and take commercially practicable measures to meet regulatory requirements and avoid or limit environmental effects, some risks are inherent in our businesses. Among the risks are costs associated with transporting and managing hazardous materials and waste disposal and plant site clean-up, fines and penalties if we are found to be in violation of law, as well as modifications, disruptions or discontinuation of certain operations or types of operations including product recalls and reformulations. Similarly, the need for certain of our products and services is dependent upon or might be limited by governmental laws and regulations. Changes in such laws and regulations, including among others, air, water, chemical and product regulations, could impact the sales of some of our products or services. In addition to an increase in costs of manufacturing and delivering products, a change in production regulations or product regulations could result in interruptions to our business and potentially cause economic or consequential losses should we be unable to meet the demands of our customers for products.

​

Additionally, although we are not currently aware of any such circumstances, there can be no assurance that future legislation or enforcement policies will not have a material adverse effect on our consolidated results of operations, financial position or cash flows. Environmental and regulatory matters most significant to us are discussed below.

​

Ingredient Legislation: Various laws and regulations have been enacted by state, local and foreign jurisdictions pertaining to the sale of products which contain phosphorous, volatile organic compounds, or other ingredients that may impact human health or the environment. Under California Proposition 65, for example, label disclosures are required for certain products containing chemicals listed by California. Chemical management initiatives that promote pollution prevention through research and development of safer chemicals and safer chemical processes are being advanced by several states.

​

Table of Contents

Environmentally preferable purchasing programs for cleaning products have been enacted in a number of states to date, and in recent years have been considered by several other state legislatures. Cleaning product ingredient disclosure legislation has been introduced in the U.S. Congress in each of the past few years but has not passed, and several states are considering further regulations in this area. In 2017, California passed the Cleaning Product Right to Know Act of 2017, that required ingredient transparency on-line and on-label by 2020 and 2021, respectively. New York has proposed similar ingredient disclosure regulation. The U.S. Government is monitoring “green chemistry” initiatives through a variety of initiatives, including its “Design for the Environment” (“DfE”)/“Safer Choice” program. DfE/Safer Choice has three broad areas of work (recognition of safer products on a DfE/Safer Choice label, development of best practices for industrial processes and evaluation of safer chemicals), and we are involved in these to varying degrees. Our Global Institutional and Global Industrial cleaning products are subject to the regulations and may incur additional stay-in-market expenses associated with conducting the required alternatives analyses for chemicals of concern. To date, we generally have been able to comply with such legislative requirements by reformulation or labeling modifications. Such legislation has not had a material adverse effect on our consolidated results of operations, financial position or cash flows to date.

​

TSCA: The nation’s primary chemicals management law, the Toxic Substances Control Act (“TSCA”), was updated for the first time in 40 years with the passage of the Frank R. Lautenberg Chemical Safety for the 21st Century Act (“LCSA”) in 2016. The LCSA modernizes the original 1976 legislation, aiming to establish greater public confidence in the safety of chemical substances in commerce and improve the U.S. Environmental Protection Agency’s (“EPA”) capability and authority to regulate existing and new chemical substances. For Ecolab, the TSCA changes mainly impact testing and submission costs for new and existing chemical substances in the United States. As a result of reform and administration changes, EPA reviews are resulting in the majority of new substances being regulated in some manner by the agency. Compliance with new requirements under TSCA are similar to the costs associated with REACH in the European Union, which is discussed below.

​

REACH: The European Union has enacted a regulatory framework for the Registration, Evaluation and Authorization of Chemicals (“REACH”), which aims to manage chemical safety risks. REACH established a European Chemicals Agency (“ECHA”) in Helsinki, Finland, which is responsible for evaluating data to determine hazards and risks and to manage this program for authorizing chemicals for sale and distribution in Europe. We met all REACH registration requirements. To help manage this program, we have been simplifying our product lines and working with chemical suppliers to comply with registration requirements. In addition, Korea, Taiwan, Turkey, India, Chile and Colombia and other countries have implemented or are implementing similar requirements. In addition, the European Green Deal will include the revision of chemical management regulation to achieve a circular economy and toxic-free environment (Chemical Strategy for Sustainability) which may impact sales in Ecolab’s raw material portfolio. Potential costs to us are not yet fully quantifiable but are not expected to have a material adverse effect on our consolidated results of operations or cash flows in any one reporting period or on our financial position.

​

GHS: In 2003, the United Nations adopted a standard on hazard communication and labeling of chemical products known as the Globally Harmonized System of Classification and Labeling of Chemicals (“GHS”). GHS is designed to facilitate international trade and increase safe handling and use of hazardous chemicals through a worldwide system that classifies chemicals based on their intrinsic hazards and communicates information about those hazards through standardized product labels and safety data sheets (“SDSs”). Most countries in which we operate have adopted or are expected to adopt GHS-related legislation by 2023. The primary cost of compliance revolves around reclassifying products and revising SDSs and product labels. We have met applicable deadlines and are working toward a phased-in approach to mitigate the costs of GHS implementation in remaining countries (e.g., Peru, Chile, India). Potential costs to us are not expected to have a material adverse effect on our consolidated results of operations or cash flows in any one reporting period or on our financial position.

​

Pesticide and Biocide Legislation: Various international, federal and state environmental laws and regulations govern the manufacture and/or use of pesticides. We manufacture and sell certain disinfecting, sanitizing and material preservation products that kill or reduce microorganisms (bacteria, viruses, fungi) on hard environmental surfaces, in process fluids and on certain food products. Such products constitute “pesticides” or “antimicrobial pesticides” under the current definitions of the Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”), as amended by the Food Quality Protection Act of 1996, the principal federal statute governing the manufacture, labeling, handling and use of pesticides. We maintain several hundred product registrations with the U.S. Environmental Protection Agency (“EPA”). Registration entails the necessity to meet certain efficacy, toxicity and labeling requirements and to pay on-going registration fees. In addition, each state in which these products are sold requires registration and payment of a fee. In general, the states impose no substantive requirements different from those required by FIFRA. However, California and certain other states have adopted additional regulatory programs, and California imposes a tax on total pesticide sales in that state. While the cost of complying with rules as to pesticides has not had a material adverse effect on our consolidated results of operations, financial condition, or cash flows to date, the costs and delays in receiving necessary approvals for these products continue to increase. Total fees paid to the EPA and the states to obtain or maintain pesticide registrations are not expected to significantly affect our consolidated results of operations or cash flows in any one reporting period or our financial position.

​

In Europe, the Biocidal Products Regulation established a program to evaluate and authorize marketing of biocidal active substances and products. We are working with suppliers and industry groups to manage these requirements and have met all relevant deadlines of the program by the timely submission of dossiers for active substances and biocide products. Anticipated registration costs, which will be incurred through the multi-year phase-in period, will be significant; however, these costs are not expected to significantly affect our consolidated results of operations or cash flows in any one reporting period or our financial position. The same is true for emerging biocide regulations in Asia.

​

In addition, Pest Elimination applies restricted-use pesticides that it generally purchases from third parties. That business must comply with certain standards pertaining to the use of such pesticides and to the licensing of employees who apply such pesticides. Such regulations are enforced primarily by the states or local jurisdictions in conformity with federal regulations. We have not experienced material difficulties in complying with these requirements.

​

FDA Antimicrobial Product Requirements: Various laws and regulations have been enacted by federal, state, local and foreign jurisdictions regulating certain products manufactured and sold by us for controlling microbial growth on humans, animals and foods. In the United States, these requirements generally are administered by the U.S. Food and Drug Administration ("FDA"). However, the U.S. Department of Agriculture and EPA also may share in regulatory jurisdiction of antimicrobials applied to food. The FDA codifies regulations for these product categories in order to ensure product quality, safety and effectiveness. The FDA also has been expanding requirements applicable to such products, including proposing regulations for over-the-counter antiseptic drug products, which may impose additional requirements associated with antimicrobial hand care products and associated costs when finalized by the FDA. FDA regulations associated with the Food Safety Modernization Act may impose additional requirements related to safety product lines. To date, such requirements have not had a material adverse effect on our consolidated results of operations, financial position or cash flows.

​

Medical Device and Drug Product Requirements: As a manufacturer, distributor and marketer of medical devices and human drugs, we also are subject to regulation by the FDA and corresponding regulatory agencies of the state, local and foreign governments in which we sell our products. These regulations govern the development, testing, manufacturing, packaging, labeling, distribution and marketing of medical devices and medicinal products, including Advanced Pharmaceutical Ingredients (“API”), excipients and resins for biopharmaceutical processing. We also are required to register with the FDA as a medical device and drug manufacturer, comply with post-market reporting (e.g., Adverse Event Reporting, MDR and Recall) requirements, and to comply with the FDA’s current Good Manufacturing Practices and Quality System Regulations which require that we have a quality system for the design and production of our products intended for commercial distribution in the United States and satisfy recordkeeping requirements with respect to our manufacturing, testing and control activities. Countries in the European Union require that certain products being sold within their jurisdictions obtain a “CE mark,” an international symbol of adherence to quality assurance standards, and be manufactured in compliance with certain requirements (e.g., Medical Device Directive 93/42/EE, Medical Device Regulation (EU) 2017/745 (“MDR”), and ISO 13485). We have CE mark approval to sell various medical device and medicinal products in Europe. Implementation of the MDR will require additional certifications and investments, including system, product and process upgrades. Our other international non-European operations also are subject to government regulation and country-specific rules and regulations. Regulators at the federal, state and local level have imposed, are currently considering and are expected to continue to impose regulations on medical devices and drug products. No prediction can be made of the potential effect of any such future regulations, and there can be no assurance that future legislation or regulations will not increase the costs of our products or prohibit the sale or use of certain products.

​

Equipment: Ecolab’s products are dispensed by equipment that is subject to state and local regulatory requirements, as well as being subject to UL, NSF, and other approval requirements. For certain digitally connected product offerings, Federal Communication Commission (“FCC”) and corresponding international requirements are applicable. We have both dedicated manufacturing facilities and third-party production of our equipment. We are developing processes to monitor and manage changing regulatory regimes and assist with equipment systems compliance. To date, such requirements have not had a material adverse effect on our consolidated results of operations, financial position or cash flows.

​

Other Environmental Legislation: Our manufacturing plants are subject to federal, state, local or foreign jurisdiction laws and regulations relating to discharge of hazardous substances into the environment and to the transportation, handling and disposal of such substances. The primary federal statutes that apply to our activities in the United States are the Clean Air Act, the Clean Water Act and the Resource Conservation and Recovery Act. We are also subject to the Superfund Amendments and Reauthorization Act of 1986, which imposes certain reporting requirements as to emissions of hazardous substances into the air, land and water. The products we produce and distribute into Europe are also subject to directives governing electrical waste (WEEE Directive 2012/19/EU) and restrictive substances (RoHS Directive 2011/65/EU). Similar legal requirements apply to Ecolab’s facilities globally. We make capital investments and expenditures to comply with environmental laws and regulations, to promote employee safety and to carry out our announced environmental sustainability principles. To date, such expenditures have not had a significant adverse effect on our consolidated results of operations, financial position or cash flows. Our capital expenditures for environmental, health and safety projects worldwide were approximately $35 million in 2022, $28 million in 2021 and $18 million in 2020. Approximately $41 million has been budgeted globally for projects in 2023. The increase in the projected spend reflects a return to historical annual expenditure levels prior to the COVID-19 pandemic.

​

Climate Change: Various laws and regulations pertaining to climate change have been implemented or are being considered for implementation at the international, national, regional and state levels, particularly as they relate to the reduction of greenhouse gas (GHG) emissions. These include proposed regulations introduced by the SEC in March 2022 relating to climate change disclosure and the European Commission’s Corporate Sustainability Reporting Directive, which came into force in December 2022 and will apply to both EU and certain non-EU companies with a phased introduction. These laws may directly impact the Company. We continue to monitor the development and implementation of such laws and regulations; however, as a matter of corporate policy, we support a balanced approach to reducing GHG emissions while sustaining economic growth.

Furthermore, climate-related risks are assessed within our Enterprise Risk Management process and Annual Business Significance Risks Assessment, which is aligned with recommendations of the Financial Stability Board (FSB) Task Force on Climate-related Financial Disclosures (TCFD). We report TCFD disclosures in our annual CDP Climate report located at https://www.ecolab.com/sustainability/sustainability-reporting-resources. We are evaluating further application of the recommendations of the TCFD in alignment with the recommended timeline from the TCFD.

​

Ecolab recognizes that climate change poses potential risks and creates potential opportunities to our organization. Ecolab has taken steps to further identify and assess the nature and magnitude of these risks and opportunities. Ecolab has been focused on assessing climate risks for the past three years, leading up to our TCFD-aligned climate risk assessment conducted in 2021. We expect to continue our efforts to assess additional climate-related risks and opportunities including, exploring our supply chain resiliency, as appropriate. Subsequently, Ecolab plans to review the results of our analysis and consider adaptation and management plans for any relevant climate change risks and to further benefit from identified opportunities for customer impact.

​

To further our climate commitment, in 2019 we announced new goals to reduce our GHG emissions by half by 2030 and achieve net zero by 2050, in alignment with the United Nations Global Compact’s Business Ambition for 1.5⁰C. In 2020, we further committed to attempt to move to 100% renewable energy by 2030 and set a science-based target (SBT) addressing our Scope 1, 2 and 3 GHG emissions. Our SBT targets reduction of absolute Scope 1 and 2 emissions by 50% by 2030 from a 2018 base year, and to work with our suppliers representing 70% of our Scope 3 emissions to set science-based reduction targets by 2024. In 2021, we invested over $1.2 million in continuous improvement projects focused on water and energy reductions at over 20 of our facilities across the globe. In all, these projects reduced annual energy consumption by almost 5.4 billion BTUs, reduced GHG emissions by 324 MT CO2e and saved 27 million gallons (~103,000 cubic meters) of water across our global supply chain manufacturing facilities. The scope of energy consumption reductions is calculated using a combination of direct measurements and estimations using best-practice methodologies. The scope of reduction in GHG emissions consumption data is an estimated annual impact and includes both Scope 1 and 2 emissions. Water reduction is calculated using the water meters and utilities data that measure the savings since our base year of calculations which was 2018.

​

In addition to managing our operational and supply chain sustainability performance, we partner with customers at more than three million customer locations around the world to reduce energy and GHG emissions through our high-efficiency solutions in cleaning and sanitation, water, paper, and energy services. Showcasing our global team’s dedication to helping our customers thrive and make a positive impact in the world, we have set a 2030 goal to help our customers reduce their GHG emissions by 6.0 million metric tons. Ecolab recognizes the climate-water nexus. As part of our 2030 Impact Goals, we have planned to restore greater than 50% of our water withdrawal and achieve Alliance for Water Stewardship Standard certification in high-risk watersheds. In addition, we aim to reduce net water withdrawals by 40% per unit of production across our enterprise. We also magnify our impact through the water-saving solutions we deliver to our customers and have set a goal to help our customers conserve more than 300 billion gallons of water annually by 2030.

​

The science of sustainability is an evolving one. For a discussion of the factors that may cause our sustainability initiatives, goals and targets to differ from those expressed above, see Item 1A of this Form 10-K, entitled “Risk Factors.”

​

Environmental Remediation and Proceedings: Along with numerous other potentially responsible parties (“PRP”), we are currently involved with waste disposal site clean-up activities imposed by the federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) or state equivalents at 17 sites in the United States. Additionally, we have similar liability at five sites outside the United States. In general, under CERCLA, we and each other PRP that actually contributed hazardous substances to a Superfund site are jointly and severally liable for the costs associated with cleaning up the site. Customarily, the PRPs will work with the EPA to agree and implement a plan for site remediation.

​

Based on an analysis of our experience with such environmental proceedings, our estimated share of all hazardous materials deposited on the sites referred to in the preceding paragraph, and our estimate of the contribution to be made by other PRPs which we believe have the financial ability to pay their shares, we have accrued our best estimate of our probable future costs relating to such known sites. In establishing accruals, potential insurance reimbursements are not included. The accrual is not discounted. It is not feasible to predict when the amounts accrued will be paid due to the uncertainties inherent in the environmental remediation and associated regulatory processes.

​

We have also been named as a defendant in a number of lawsuits alleging personal injury due to exposure to hazardous substances, including multi-party lawsuits alleging personal injury in connection with our products and services. While we do not believe that any of these suits will be material to us based upon present information, there can be no assurance that these environmental matters could not have, either individually or in the aggregate, a material adverse effect on our consolidated results of operations, financial position or cash flows.

​

We have also been named as a defendant in lawsuits where our products have not caused injuries, but the claimants wish to be monitored for potential future injuries. We cannot predict with certainty the outcome of any such tort claims or the involvement we or our products might have in such matters in the future, and there can be no assurance that the discovery of previously unknown conditions will not require significant expenditures. In each of these chemical exposure cases, our insurance carriers have accepted the claims on our behalf (with or without reservation) and our financial exposure should be limited to the amount of our deductible; however, we cannot predict the number of claims that we may have to defend in the future and we may not be able to continue to maintain such insurance.

Our worldwide net expenditures for contamination remediation were approximately $1.4 million in 2022, $0.5 million in 2021 and $0.6 million in 2020. Our worldwide accruals at December 31, 2022 for probable future remediation expenditures, excluding potential insurance reimbursements, totaled approximately $9.6 million. We review our exposure for contamination remediation costs periodically and our accruals are adjusted as considered appropriate. While the final resolution of these issues could result in costs below or above current accruals and, therefore, have an impact on our consolidated financial results in a future reporting period, we believe the ultimate resolution of these matters will not have a material effect on our consolidated results of operations, financial position or cash flows.

​

Economic & Operational Risks

​

Our results are impacted by general worldwide economic factors.

​

The COVID pandemic, geopolitical instability, including the conflict between Russia and Ukraine, and other global events have significantly increased economic and demand uncertainty. Some of the results of these events, including supply chain challenges, inflation, high interest rates, foreign currency exchange volatility, and volatility in global capital markets, have affected our business in the past and could continue to have a material adverse impact on our business in the future. Countries such as Russia, Turkey and Argentina have recently experienced economic upheaval and similar upheaval in other countries with Ecolab operations could have a material adverse impact on our consolidated results of operations, financial position and cash flows by negatively impacting economic activity, including in our key end-markets, and by further weakening the local currency versus the U.S. dollar, resulting in reduced sales and earnings from our foreign operations, which are generated in the local currency, and then translated to U.S. dollars.

​

Our results depend upon the continued vitality of the markets we serve.

​

Economic downturns, and in particular downturns in our larger markets including the foodservice, hospitality, travel, health care, food processing, refining, pulp and paper, mining and steel industries, can adversely impact our customers. In particular, we expect a more challenging macroeconomic environment, especially in Europe, as the war and the energy crisis are having a significant impact on costs and demand. Additionally, the last three years we have experienced the negative impact of the COVID-19 pandemic on the demand for our products and services provided to customers in the full-service restaurant, hospitality, lodging and entertainment industries. In prior years, the weaker global economic environment has also negatively impacted certain of our end-markets. During these periods of weaker economic activity, our customers and potential customers may reduce or discontinue their volume of purchases of cleaning and sanitizing products and water treatment and process chemicals, which has had, and may continue to have, a material adverse effect on our business, financial condition, results of operation or cash flows.

​

Our significant non-U.S. operations expose us to global economic, political and legal risks that could impact our profitability.

​

We have significant operations outside the United States, including joint ventures and other alliances. We conduct business in more than 170 countries and, in 2022, approximately 47% of our net sales originated outside the United States. There are inherent risks in our international operations, including:

​

​

In light of Russia’s invasion of Ukraine and the United States’ and other countries’ sanctions against Russia, we announced in April 2022 that we will focus our Russian business on operations that are essential to life, providing minimal support for our healthcare, life sciences, food and beverage and certain water businesses. We may further narrow our presence in Russia depending on developments in the conflict or otherwise. Our Russian operations represented approximately 1% for both our 2022 and 2021 annual sales. During 2022 we recorded pre-tax charges of $13.1 million related to recoverability risk of certain assets in both Russia and Ukraine. Depending on developments, we may incur further charges relating to our Russia and Ukraine businesses. The conflict in Ukraine may escalate and/or expand in scope and the broader consequences of this conflict, which have included and/or may in the future include sanctions, embargoes, regional instability and geopolitical shifts; potential retaliatory action by the Russian government against companies, including us, such as nationalization of foreign businesses in Russia; and increased tensions between the United States and countries in which we operate cannot be predicted, nor can we predict the conflict’s impact on the global economy and on our business and financial results. The Russia and Ukraine conflict may also heighten many other risks disclosed in our report on Form 10-K, any of which could

materially and adversely affect our business and financial results. Such risks include, but are not limited to, adverse effects on macroeconomic conditions, including increased inflation, constraints on the availability of commodities, supply chain disruption and decreased business spending; disruptions to our or our business partners’ global technology infrastructure, including through cyber-attack or cyber-intrusion; adverse changes in international trade policies and relations; claims, litigation and regulatory enforcement; our ability to implement and execute our business strategy; terrorist activities; our exposure to foreign currency fluctuations; reputational risk; and constraints, volatility, or disruption in the capital markets.

​

Additionally, changes in U.S. or foreign government policy on international trade, including the imposition or continuation of tariffs, could materially and adversely affect our business. In 2018, the U.S. imposed tariffs on certain imports from China and other countries, resulting in retaliatory tariffs by China and other countries. While the U.S. and China signed a Phase One trade agreement in January 2020, which included the suspension and rollback of tariffs, the CHIPS and Science Act of 2022 with objectives including countering China’s technical ambitions was signed into law in August 2022. Any new tariffs or policies imposed by the U.S., China or other countries or any additional retaliatory measures by any of these countries, could increase our costs, reduce our sales and earnings or otherwise have an adverse effect on our operations.

​

Further, our operations outside the United States require us to comply with a number of United States and non-U.S. laws and regulations, including anti-corruption laws such as the United States Foreign Corrupt Practices Act and the United Kingdom Bribery Act, as well as U.S. and non-U.S. economic sanctions regulations. We have internal policies and procedures relating to such laws and regulations; however, there is risk that such policies and procedures will not always protect us from the misconduct or reckless acts of employees or representatives, particularly in the case of recently acquired operations that may not have significant training in applicable compliance policies and procedures. Violations of such laws and regulations could result in disruptive investigations, significant fines and sanctions, which could have a material adverse effect on our consolidated results of operations, financial position or cash flows.

​

Also, because of uncertainties regarding the interpretation and application of laws and regulations and the enforceability of intellectual property and contract rights, we face risks in some countries that our intellectual property rights and contract rights would not be enforced by local governments. We are also periodically faced with the risk of economic uncertainty, which has impacted our business in some countries. Other risks in international business also include difficulties in staffing and managing local operations, including managing credit risk to local customers and distributors.

​

Our overall success as a global business depends, in part, upon our ability to succeed in differing economic, social, legal and political conditions. We may not continue to succeed in developing and implementing policies and strategies that are effective in each location where we do business, which could have a material adverse effect on our consolidated results of operations, financial position or cash flows.

​

Our results could be materially and adversely affected by difficulties in securing the supply of certain raw materials or by fluctuations in the cost of raw materials.

​

The prices of raw materials used in our business fluctuate, and in recent years we have experienced periods of significant increased raw material costs. Changes in raw material prices, unavailability of adequate and reasonably priced raw materials or substitutes for those raw materials, or the inability to obtain or renew supply agreements on favorable terms has materially and adversely affected our business and can in the future materially and adversely affect our consolidated results of operations, financial position or cash flows. In addition, volatility and disruption in economic activity and conditions could disrupt or delay the performance of our suppliers and thus impact our ability to obtain raw materials at favorable prices or on favorable terms, which may materially and adversely affect our business.

​

We depend on key personnel to lead our business; the labor market is very dynamic.

​

Our continued success will largely depend on our ability to attract, retain and develop a high caliber of talent and on the efforts and abilities of our executive officers and certain other key employees, particularly those with sales and sales management responsibilities to drive business growth, development and profitability. As we continue to grow our business, make acquisitions, expand our geographic scope and offer new products and services, we need the organizational talent necessary to ensure effective succession for executive officer and key employee roles in order to meet the growth, development and profitability goals of our business. Our operations could be materially and adversely affected if for any reason we were unable to attract, retain or develop such officers or key employees and successfully execute organizational change and management transitions at leadership levels. More generally, in the wake of the COVID-19 pandemic, expectations from qualified talent in many areas of the labor market have evolved. In light of this, if we are unable to attract and retain employees on terms and conditions that are consistent with our historical operating model, our business could be disrupted or our costs could increase, which may materially and adversely affect our business

​

We are subject to information technology system failures, network disruptions and breaches in data security.

​

We rely to a large extent upon information technology systems and infrastructure to operate our business. The size and complexity of our information technology systems and those of strategic vendors make them vulnerable to failure, malicious intrusion and random attack. Acquisitions have resulted in further de-centralization of systems and additional complexity in our systems infrastructure. Likewise, data security breaches by employees or others with permitted access to our systems or to the systems of strategic vendors pose a risk that sensitive data may be exposed to unauthorized persons or to the public. Geopolitical tensions or conflicts, such as Russia’s invasion of Ukraine, may further heighten the risk of cybersecurity attacks. While we have invested in protection of data and information technology, we have experienced immaterial cybersecurity attacks and incidents, and there can be no assurance that our efforts will prevent failures, cybersecurity attacks or breaches in our systems or in the systems of strategic vendors that could cause reputational damage, business

disruption or legal and regulatory costs; could result in third-party claims; could result in compromise or misappropriation of our intellectual property, trade secrets or sensitive information; or could otherwise adversely affect our business. Certain of our customer offerings include digital components, such as remote monitoring of certain customer operations. A breach of those remote monitoring systems could expose customer data giving rise to potential third-party claims and reputational damage. There may be other related challenges and risks as we complete implementation of our ERP system upgrade.

​

The COVID-19 pandemic and measures taken in response thereto have materially and adversely impacted, and we expect may continue to materially and adversely impact, our business and results of operations, and the full impact of the pandemic will depend on future developments, which are highly uncertain and cannot be predicted.

​

Beginning in March 2020, the COVID-19 pandemic had a rapid and significant negative impact on the global economy, including a significant downturn in the foodservice, hospitality and travel industries. Measures taken to alleviate the pandemic (such as stay-at-home orders and other responsive measures) significantly impacted our restaurant and hospitality customers and negatively affected demand for our products and services in these segments, resulting in a material adverse effect on our business and results of operations. There is continued uncertainty regarding the duration, scope and severity of the pandemic, particularly with the emergence of new variants of COVID-19 and periodic spikes in COVID-19 cases in various geographic regions, and the impacts on our business and the global economy from the effects of the pandemic and response measures. Travel and logistics restrictions, lockdowns, vaccine requirements and other measures from time to time implemented by foreign and domestic authorities have resulted in, and may continue to result in, supply chain and transportation disruptions, production delays and capacity limitations at Ecolab and some of its customers and suppliers, as well as reduced workforce availability or productivity at Ecolab and customer sites, and additional data, information and cyber security risks associated with an extensive workforce working remotely.

​

The degree to which the pandemic ultimately impacts our business, financial condition and results of operations and the global economy will depend on future developments beyond our control, which are highly uncertain and difficult to predict, including the severity, duration and any resurgence of the pandemic, the extent, duration and effectiveness of periodic lockdowns and other containment actions, the availability, public adoption and efficacy of COVID vaccines, how quickly and to what extent normal economic and operating activity can resume, and the severity and duration of resulting global economic volatility.

​

Besides the COVID-19 pandemic, the United States and other countries have experienced, and may experience in the future, public health outbreaks such as Zika virus, Avian Flu, SARS and H1N1 influenza. A prolonged occurrence of a contagious disease such as these could result in a significant downturn in the foodservice, hospitality and travel industries and also may result in health or other government authorities imposing restrictions on travel further impacting our end markets. Any of these events could result in a significant drop in demand for some of our products and services and materially and adversely affect our business.

​

Strategic Risks

​

If we are unsuccessful in integrating acquisitions, including Purolite, our business could be materially and adversely affected.

​

In December 2021 we acquired Purolite, which operates in the highly regulated life sciences, pharma and biopharma industries and has extensive international operations which complicate integration execution. If we have difficulty integrating Purolite operations or lose key employees or customers, our business could be materially and adversely affected. Additionally, as part of our long-term strategy, we seek to acquire complementary businesses. There can be no assurance that we will find attractive acquisition candidates or succeed at effectively managing the integration of acquired businesses into existing businesses. If the underlying business performance of such acquired businesses deteriorates, the expected synergies from such transactions do not materialize or we fail to successfully integrate new businesses into our existing businesses, our consolidated results of operations, financial position or cash flows could be materially and adversely affected.

​

If we are unsuccessful in executing on key business initiatives, including restructurings and our Enterprise Resource Planning (“ERP”) system upgrades, our business could be materially and adversely affected.

​

We continue to execute key business initiatives, including restructurings and investments to develop business systems, as part of our ongoing efforts to improve our efficiency and returns. In particular, we are undertaking the three restructuring plans, i.e. the Europe Program, the Institutional Advancement Program and Accelerate 2020 plan to simplify and automate processes and tasks, reduce complexity and management layers, consolidate facilities and focus on key long term growth areas by leveraging technology and structural improvements as discussed under Note 3 entitled “Special (Gains) and Charges” of this Form 10-K. Additionally, we are continuing implementation of our ERP system upgrades, which are expected to continue in phases over the next several years. These upgrades, which include sales, supply chain and certain finance functions, are expected to improve the efficiency of certain financial and related transactional processes. These upgrades involve complex business process design and a failure of certain of these processes could result in business disruption. If the projects in which we are investing or the initiatives which we are pursuing are not successfully executed, our consolidated results of operations, financial position or cash flows could materially and adversely be affected.

​

Our growth depends upon our ability to compete successfully with respect to value, innovation and customer support.

​

We have numerous global, national, regional and local competitors. Our ability to compete depends in part on providing high quality and high value-added products, technology and service. We must also continue to identify, develop and commercialize innovative, profitable and high value-added products for niche applications and commercial digital applications. We have made significant investments in commercial digital product offerings, and our culture and expertise must continue to evolve to develop, support and profitably deploy commercial digital offerings, which are becoming an increasingly important part of our business. There can be no assurance that we will

19

Table of Contents

be able to accomplish our technology development goals or that technological developments by our competitors will not place certain of our products, technology or services at a competitive disadvantage in the future. In addition, certain of the new products that we have under development will be offered in markets in which we do not currently compete, and there can be no assurance that we will be able to compete successfully in those new markets. If we fail to introduce new technologies or commercialize our digital offerings on a timely and profitable basis, we may lose market share and our consolidated results of operations, financial position or cash flows could be materially and adversely affected.

​

Consolidation of our customers and vendors could materially and adversely affect our results.

​

Customers and vendors in the foodservice, hospitality, travel, healthcare, energy, life sciences, food processing and pulp and paper industries, as well as other industries we serve, have consolidated in recent years and that trend may continue. This consolidation could have a material adverse impact on our ability to retain customers and on our pricing, margins and consolidated results of operations.

​

We enter into multi-year contracts with customers that could impact our results.

​

Our multi-year contracts with some of our customers include terms affecting our pricing flexibility. There can be no assurance that these restraints will not have a material adverse impact on our margins and consolidated results of operations.

​

Legal, Regulatory & Compliance Risks

​

Our business depends on our ability to comply with laws and governmental regulations and meet our contractual commitments and failure to do so could materially and adversely impact our business; and we may be materially and adversely affected by changes in laws and regulations.

​

Our business is subject to numerous laws and regulations relating to the environment, including evolving climate change standards, and to the manufacture, storage, distribution, sale and use of our products as well as to the conduct of our business generally, including employment and labor laws and anti-corruption laws. Furthermore, increasing public and governmental awareness and concern regarding the effects of climate change has led to significant legislative and regulatory efforts to limit greenhouse gas emissions and will likely result in further environmental and climate change laws and regulations. Compliance with these laws and regulations exposes us to potential financial liability and increases our operating costs. A violation of these laws and regulations could expose us to financial liability that may have a material adverse effect on our results of operations and cash flows. Regulation of our products and operations continues to increase with more stringent standards, causing increased costs of operations and potential for liability if a violation occurs. The potential cost to us relating to environmental and product registration laws and regulations is uncertain due to factors such as the unknown magnitude and type of possible contamination and clean-up costs, the complexity and evolving nature of laws and regulations, and the timing and expense of compliance. Changes to current laws (including tax laws), regulations and policies could impose new restrictions, costs or prohibitions on our current practices which would have a material adverse effect on our consolidated results of operations, financial position or cash flows. Changes to labor and employment laws and regulations, as well as related rulings by courts and administrative bodies, could materially and adversely affect our operations and expose us to potential financial liability.

​

Defense of litigation, particularly certain types of actions such as antitrust, patent infringement, personal injury, product liability, breach of contract, wage hour and class action lawsuits, can be costly and time consuming even if ultimately successful, and if not successful could have a material adverse effect on our consolidated results of operations, financial position or cash flows.

​

A chemical spill or release could materially and adversely impact our business.

​

As a manufacturer and supplier of chemical products, there is a potential for chemicals to be accidentally spilled, released or discharged, either in liquid or gaseous form, during production, transportation, storage or use. Such a release could result in environmental contamination as well as a human or animal health hazard. Accordingly, such a release could have a material adverse effect on our consolidated results of operations, financial position or cash flows.

​

Potential indemnification liabilities pursuant to the separation and split-off of our Upstream Energy business could materially and adversely affect our business and financial statements.

​

With respect to the separation and subsequent split-off of our Upstream Energy business, we entered into a separation and distribution agreement with ChampionX Holding Inc. and ChampionX Corporation (f/k/a Apergy Corporation and taken together with ChampionX Holding Inc., “ChampionX”) as well as certain other agreements to govern the separation and related transactions and our relationship with ChampionX going forward. These agreements provide for specific indemnity and certain other obligations of each party and could lead to disputes between ChampionX and us. If we are required to indemnify ChampionX under the circumstances set forth in these agreements, we may be subject to substantial related liabilities. In addition, with respect to the liabilities for which ChampionX has agreed to indemnify us under these agreements, there can be no assurance that the indemnity rights we have against ChampionX will be sufficient to protect us against the full amount of such liabilities, or that ChampionX will be able to fully satisfy its indemnification obligations. Each of these risks could negatively affect our business and our consolidated results of operations, financial position or cash flows could be materially and adversely affected.

​

Table of Contents

Extraordinary events may significantly impact our business.

​

The occurrence of (a) litigation or claims, (b) the loss or insolvency of a major customer or distributor, (c) repeated or prolonged federal government shutdowns or similar events, (d) war (including acts of terrorism or hostilities which impact our markets), (e) natural or manmade disasters, (f) water shortages or (g) severe weather conditions affecting our operations or the energy, foodservice, hospitality and travel industries may have a material adverse effect on our business.

​

While we have a diverse customer base and no customer or distributor constitutes 10 percent or more of our consolidated revenues, we do have customers and independent, third-party distributors, the loss of which could have a material adverse effect on our consolidated results of operations or cash flows for the affected earnings periods.

​

Government shutdowns can have a material adverse effect on our consolidated results of operations or cash flows by disrupting or delaying new product launches, renewals of registrations for existing products and receipt of import or export licenses for raw materials or products.

​

War (including acts of terrorism or hostilities), natural or manmade disasters, water shortages or severe weather conditions, including the effects of climate change, affecting the energy, foodservice, hospitality, travel, health care, food processing, pulp and paper, mining, steel and other industries can cause a downturn in the business of our customers, which in turn can have a material adverse effect on our consolidated results of operations, financial position or cash flows. In particular, the U.S. Gulf Coast is a region with significant refining, petrochemicals and chemicals operations which provide us raw materials, as well as being an important customer base for our Downstream and Water operating segments. Hurricanes or other severe weather events impacting the Gulf Coast, such as the winter freeze in Texas and the Gulf Coast in February 2021, can materially and adversely affect our ability to obtain raw materials at reasonable cost, or at all, and could adversely affect our business with our customers in the region.

​

Our commitments, goals, targets, objectives and initiatives related to sustainability, and our public statements and disclosures regarding them, expose us to numerous risks.

​

We have developed, and will continue to establish, goals, targets, and other objectives related to sustainability matters, including our sustainability goals in alignment with the United Nations Global Compact’s Business Ambition for 1.5⁰C and our commitments to science-based targets addressing Scope 1, 2 and 3 GHG emissions, discussed in Item 1 of Part I of this Form 10-K, entitled “Business.” Achieving these goals and commitments will require evolving our business, capital investment and the development of technology that might not currently exist. We might incur additional expense or be required to recognize impairment charges in connection with our efforts. These commitments, goals, targets and other objectives reflect our current plans and there is no guarantee that they will be achieved. Our efforts to research, establish, accomplish, and accurately report on these commitments, goals, targets, and objectives expose us to operational, reputational, financial, legal, and other risks. Our ability to achieve any stated commitment, goal, target, or objective is subject to factors and conditions, many of which are outside of our control, including the pace of changes in technology, the availability of requisite financing, and the availability of suppliers that can meet our sustainability and other standards.

​

Our business may face increased scrutiny from the investment community, other stakeholders, regulators, and the media related to our sustainability activities, including our commitments, goals, targets, and objectives, and our methodologies and timelines for pursuing them. If our sustainability practices do not meet investor or other stakeholder expectations and standards, which continue to evolve, our reputation, our ability to attract or retain employees, and our attractiveness as an investment, business partner, or as an acquiror could be negatively impacted. Similarly, our failure or perceived failure to pursue or fulfill our commitments, goals, targets, and objectives, to comply with ethical, environmental, or other standards, regulations, or expectations, or to satisfy reporting standards with respect to these matters, within the timelines we announce, or at all, could have operational, reputational, financial and legal impacts.

​

Financial Risks

​

If the separation and split-off of our Upstream Energy business or certain internal transactions undertaken in anticipation of the divestiture are determined to be taxable in whole or in part, we and our stockholders may incur significant tax liabilities.

​

In connection with the separation and split-off of our Upstream Energy business that was consummated on June 3, 2020, we obtained opinions of outside tax counsel that the related merger and exchange offer will qualify as tax-free transactions to us and our stockholders, except to the extent that cash was paid to Ecolab stockholders in lieu of fractional shares. We have not sought or obtained a ruling from the Internal Revenue Service (IRS) on the tax consequences of these transactions. An opinion of counsel is not binding on the IRS or the courts, which may disagree with the opinion. Even if the merger and exchange offer otherwise qualified as tax-free transactions, they may become taxable to us if certain events occur that affect either Ecolab or ChampionX Corporation. While ChampionX Corporation has agreed not to take certain actions that could cause the transactions not to qualify as tax-free transactions and is generally obligated to indemnify us against any tax consequences if it breaches this agreement, the potential tax liabilities could have a material adverse effect on us if we were not entitled to indemnification or if the indemnification obligations were not fulfilled. If the merger or exchange offer were determined to be taxable, we could be subject to a substantial tax liability, and each U.S. holder of our common stock who participated in the exchange offer could be treated as exchanging the Ecolab shares surrendered for ChampionX Corporation shares in a taxable transaction.

​

Changes in tax laws and unanticipated tax liabilities could materially and adversely affect the taxes we pay and our profitability.

​

We are subject to income and other taxes in the United States and foreign jurisdictions, and our operations, plans and results are affected by tax and other initiatives around the world. In particular, we are affected by the impact of changes to tax laws or related authoritative interpretations in the United States, such as the Inflation Reduction Act (IRA) signed into law on August 16, 2022, which includes a corporate alternative minimum tax on certain large corporations, incentives to address climate change mitigation and other non-income tax provisions, including an excise tax on the repurchase of corporate stock. We are also subject to changes in tax law outside the United States and actions taken with respect to tax-related matters by associations such as the Organization for Economic Co-operation and Development (“OECD”), which represents a coalition of member countries, and the European Commission which influence tax policies in countries where we operate. For example, approximately 140 countries have agreed to the OECD’s two-pillar base erosion and profit shifting project (“BEPS”). This framework, which could be implemented in some countries as early as 2023, is focused on a number of issues, including shifting taxing rights on income from residence countries to source countries and establishing a minimum 15% global tax rate. Some of the BEPS and related proposals, if enacted into law in the United States and in the foreign countries where we do business, could increase the burden and costs of our tax compliance, the amount of taxes we incur in those jurisdictions and our global effective tax rate. In addition, we are impacted by settlements of pending or any future adjustments proposed by the IRS or other taxing authorities in connection with our tax audits, all of which will depend on their timing, nature and scope. Increases in income tax rates, changes in income tax laws or unfavorable resolution of tax matters could have a material adverse impact on our financial results.

​

Future events may impact our deferred tax position, including the utilization of foreign tax credits and undistributed earnings of international affiliates that are considered to be reinvested indefinitely.

​

We evaluate the recoverability of deferred tax assets and the need for deferred tax liabilities based on available evidence. This process involves significant management judgment about assumptions that are subject to change from period to period based on changes in tax laws or variances between future projected operating performance and actual results. We are required to establish a valuation allowance for deferred tax assets if we determine, based on available evidence at the time the determination is made, that it is more likely than not that some portion or all of the deferred tax assets will not be realized. In making this determination, we evaluate all positive and negative evidence as of the end of each reporting period. Future adjustments (either increases or decreases), to the deferred tax asset valuation allowance are determined based upon changes in the expected realization of the net deferred tax assets. The realization of the deferred tax assets ultimately depends on the existence of sufficient taxable income in either the carry-back or carry-forward periods under the tax law. Due to significant estimates used to establish the valuation allowance and the potential for changes in facts and circumstances, it is reasonably possible that we will be required to record adjustments to the valuation allowance in future reporting periods. Changes to the valuation allowance or the amount of deferred tax liabilities could have a material adverse effect on our consolidated results of operations or financial position. Further, should we change our assertion regarding the permanent reinvestment of the undistributed earnings of international affiliates, a deferred tax liability may need to be established.

​

Our indebtedness may limit our operations and our use of our cash flow, and any failure to comply with the covenants that apply to our indebtedness could materially and adversely affect our liquidity and financial statements.

​

As of December 31, 2022, we had approximately $8.6 billion in outstanding indebtedness, with approximately $1.5 billion in the form of floating rate debt. Our debt level and related debt service obligations may have negative consequences, including:

​

​

​

​

​

If we add new debt, the risks described above could increase.

​

We incur significant expenses related to the amortization of intangible assets and may be required to report losses resulting from the impairment of goodwill or other assets recorded in connection with the Nalco and Purolite transactions and other acquisitions.

​

We expect to continue to complete selected acquisitions and joint venture transactions in the future. In connection with acquisition and joint venture transactions, applicable accounting rules generally require the tangible and intangible assets of the acquired business to be recorded on the balance sheet of the acquiring company at their fair values. Intangible assets other than goodwill are required to be amortized over their estimated useful lives and this expense may be significant. Any excess in the purchase price paid by the acquiring company over the fair value of tangible and intangible assets of the acquired business is recorded as goodwill. If it is later determined that the anticipated future cash flows from the acquired business may be less than the carrying values of the assets and goodwill of the acquired business, the assets or goodwill may be deemed to be impaired. In this case, the acquiring company may be required under applicable accounting rules to write down the value of the assets or goodwill on its balance sheet to reflect the extent of the impairment. This write-down of assets or goodwill is generally recognized as a non-cash expense in the statement of operations of the acquiring company for the accounting period during which the write down occurs. As of December 31, 2022, we had goodwill of $8.0 billion which

22

Table of Contents

is maintained in various reporting units, including goodwill from the Nalco and Purolite transactions. If we determine that any of the assets or goodwill recorded in connection with the Nalco transaction or any other prior or future acquisitions or joint venture transactions have become impaired, we will be required to record a loss resulting from the impairment. Impairment losses could be significant and could have a material adverse effect on our consolidated results of operations and financial position.

Item 2. Properties.

​

Our manufacturing philosophy is to manufacture products wherever an economic, process or quality assurance advantage exists or where proprietary manufacturing techniques dictate in-house production. Currently, most products that we sell are manufactured at our facilities. We position our manufacturing locations and warehouses in a manner to permit ready access to our customers.

​

Our manufacturing facilities produce chemical products as well as medical devices and equipment for all of our operating segments, although Pest Elimination purchases the majority of their products and equipment from outside suppliers. Our chemical production process consists of blending purchased raw materials into finished products in powder, liquid, and solid form. Additionally, intermediates from reaction chemistries are used in some of the blends and are also packaged directly into finished goods. Our devices and equipment manufacturing operations consist of producing chemical product dispensers and injectors and other mechanical equipment, medical devices, dishwasher racks, related sundries, dish machine refurbishment and water monitoring and maintenance equipment system from purchased components and subassemblies.

​

The following table profiles our more significant physical properties with approximately 70,000 square feet or more with ongoing production activities, as well as certain other facilities important in terms of specialization and sources of supply. In general, manufacturing facilities located in the United States serve our U.S. markets and facilities located outside of the United States serve our international markets. However, most of the United States facilities do manufacture products for export.

​

Generally, our manufacturing facilities are adequate to meet our existing in-house production needs. We continue to invest in our plant sites to maintain viable operations and to add capacity as necessary to meet business imperatives.

​

Most of our manufacturing plants also serve as distribution centers. In addition, we operate distribution centers around the world, most of which are leased, and utilize third party logistics service providers to facilitate the distribution of our products and services.

​

Our corporate headquarters is comprised of a 17-story building that we own in St. Paul, Minnesota. We also own a 115-acre campus in Eagan, Minnesota that houses a significant research and development center, a data center and training facilities as well as several of our administrative functions. We also have a significant business presence in Naperville, Illinois, where our Water and Paper operating segments maintain their principal administrative offices and research center, as well as in Greensboro, North Carolina, where our Specialty operating segment maintains its principal administrative offices and a research center. Our Downstream operating segment leases administrative and research facilities in Sugar Land, Texas and maintains additional Company-owned research facilities in Fresno, Texas.

​

Significant regional administrative and/or research facilities are located in Campinas, Brazil; Leiden, Netherlands; and Pune, India, which we own, and in Dubai, UAE; Monheim, Germany; Singapore; Shanghai, China; and Zurich, Switzerland, which we lease. We also have a network of small leased sales offices in the United States and, to a lesser extent, in other parts of the world.

Comparability of Results

​

Purolite acquisition

​

In December 2021, we acquired Purolite for total consideration of $3.7 billion in cash, net of cash acquired. Purolite is a leading and fast-growing global provider of high-end ion exchange resins for the separation and purification of solutions for pharmaceutical and industrial applications. Headquartered in King of Prussia, Pennsylvania, Purolite operates in more than 30 countries. Purolite is reported within our Life Sciences operating segment. Acquisition and integration charges are recorded within special (gains) and charges. The 2021 impacts of the Purolite acquisition including operating results, acquisition-related amortization and interest expense related to the transaction were also excluded from 2021 adjusted results.

In June 2020, we completed the previously announced separation of our Upstream Energy business (the “ChampionX business”) in a Reverse Morris Trust transaction (the “Transaction”) through the split-off of ChampionX Holding Inc. (“ChampionX”), formed by Ecolab as a wholly owned subsidiary to hold the ChampionX Business, followed immediately by the merger of ChampionX (the “Merger”) with a wholly owned subsidiary of ChampionX Corporation (f/k/a Apergy Corporation, “Apergy”).

​

The ChampionX business met the criteria to be reported as discontinued operations because the separation of ChampionX was a strategic shift in business that had a major effect on our operations and financial results. Therefore, we reported the historical results of ChampionX, including the results of operations, cash flows, and related assets and liabilities, as discontinued operations for 2020. Unless otherwise noted, the accompanying MD&A has been revised to reflect the ChampionX business as discontinued operations and 2020 balances have been revised accordingly to reflect continuing operations only.

​

Comparability of Reportable Segments

​

We have also made immaterial changes to our segment reporting, including the movement of certain customers and cost allocations between reportable segments.

​

Impact of Acquisitions and Divestitures

​

Acquisition adjusted growth rates exclude the results of our acquired businesses from the first twelve months post acquisition, the results of our divested businesses from the twelve months prior to divestiture. Further, we have excluded the results of our Purolite business for all of 2022 to remain comparable to 2021 when Purolite’s results were excluded from adjusted results. As part of the separation of the ChampionX business, we also entered into a Master Cross Supply and Product Transfer agreement with ChampionX to provide, receive or transfer certain products for a period up to 36 months. Sales of product to ChampionX under this agreement are recorded in product and equipment sales in the Corporate segment along with the related cost of sales. These transactions are removed from the consolidated results as part of the calculation of the impact of acquisitions and divestitures.

​

Fixed Currency Foreign Exchange Rates

​

Management evaluates the sales and operating income performance of our non-U.S. dollar functional currency international operations based on fixed currency exchange rates, which eliminate the impact of exchange rate fluctuations on our international operations. Fixed currency amounts are updated annually at the beginning of each year based on translation into U.S. dollars at foreign currency exchange rates established by management, with all periods presented using such rates. Public currency rate data provided within the “Segment Performance” section of this MD&A reflect amounts translated at actual public average rates of exchange prevailing during the corresponding period and is provided for informational purposes only.

EXECUTIVE SUMMARY

​

In 2022, we delivered double-digit sales growth as we accelerated our pricing and drove volume growth. Our strong pricing increases offset continued significant delivered product cost increases on a dollar basis. Our team generated double-digit sales growth in the Institutional & Specialty, Industrial and Other segments while Healthcare & Life Sciences segment sales were stable. Operating income was stable, as accelerating pricing was offset by higher delivered product costs and investments in the business.

​

Sales

​

Reported sales increased 11% to $14.2 billion in 2022 from $12.7 billion in 2021. When measured in fixed rates of foreign currency exchange, fixed currency sales increased 16% compared to the prior year. Acquisition adjusted fixed currency sales increased 13% compared to the prior year.

​

Gross Margin

​

Our reported gross margin was 37.8% of sales for 2022, compared to our 2021 reported gross margin of 40.2%. Excluding the impact of special (gains) and charges and the 2021 impacts from the Purolite transaction included in cost of sales, our adjusted gross margin was 38.2% in 2022 and 40.9% in 2021. Our gross profit increased as our strong pricing exceeded substantial delivered product cost inflation.

​

Operating Income

​

Reported operating income remained stable at $1.6 billion in 2022, compared to $1.6 billion in 2021. Adjusted operating income, excluding the impact of special (gains) and charges and the 2021 impacts of the Purolite transaction, decreased 1% in 2022, as strong pricing offset substantial delivered product inflation and investments in the business. When measured in fixed rates of foreign currency exchange, adjusted fixed currency operating income increased 4% in 2022.

​

Earnings from Continuing Operations Attributable to Ecolab Per Common Share (“EPS”)

​

Reported diluted EPS decreased 3% to $3.81 in 2022 compared to $3.91 in 2021. Special (gains) and charges had an impact on both years. Special (gains) and charges in 2022 were driven primarily by restructuring and pension settlement expense and 2021 was driven primarily by COVID-19 related charges, restructuring charges and pension settlement expense. Adjusted diluted EPS, which exclude the impact of special (gains) and charges, the 2021 impacts of the Purolite transaction and discrete tax items decreased 4% to $4.49 in 2022 compared to $4.69 in 2021, as unfavorable foreign currency translation and increases in interest expense further offset our operating income performance.

​

Balance Sheet

​

We remain committed to maintaining “A” range ratings metrics over the long-term, supported by our current credit ratings of A-/A3/A- by Standard & Poor’s, Moody’s Investor Services and Fitch, respectively. Our strong balance sheet has allowed us continued access to capital at attractive rates.

​

Cash Flow

​

Cash flow from continuing operations operating activities was $1.8 billion in 2022 compared to $2.1 billion in 2021. We continued to generate strong cash flow from operations, allowing us to fund our ongoing operations, investments in our business, acquisitions, debt repayments, pension obligations and return cash to our shareholders through share repurchases and dividend payments.

​

Dividends

​

Dividends declared per common share in 2022 was $2.06 per share. In December 2022 we increased our quarterly cash dividend by 4% to $0.53 per share, representing our 31st consecutive annual dividend rate increase. We have paid cash dividends on our common shares for 86 consecutive years. Our outstanding dividend history reflects our long term growth and development, strong cash flows, solid financial position and confidence in our business prospects for the years ahead.

CRITICAL ACCOUNTING ESTIMATES

​

Our consolidated financial statements are prepared in accordance with U.S. GAAP. We have adopted various accounting policies to prepare the consolidated financial statements in accordance with U.S. GAAP. Our significant accounting policies are disclosed in Note 2 of the Notes to the Consolidated Financial Statements (“Notes”).

​

Preparation of our consolidated financial statements, in conformity with U.S. GAAP, requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates are considered to be critical if they meet both of the following criteria: (1) the estimate requires assumptions to be made about matters that are highly uncertain at the time the accounting estimate is made, and (2) different estimates that we reasonably could have used for the accounting estimate in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, have a material impact on the presentation of our financial condition or results of operations.

​

In March 2020, COVID-19 was declared a pandemic by the World Health Organization. As the impact of the pandemic continues to evolve, estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require judgment. These estimates and assumptions may change in future periods and will be recognized in the consolidated financial information as new events occur and additional information becomes known. To the extent actual results differ materially from those estimates and assumptions, our future financial statements could be affected.

​

Besides estimates that meet the “critical” estimate criteria, we make many other accounting estimates in preparing our financial statements and related disclosures. All estimates, whether or not deemed critical, affect reported amounts of assets, liabilities, revenues or expenses as well as disclosures of contingent assets and liabilities. Estimates are based on experience and other information available prior to the issuance of the financial statements. Materially different results can occur as circumstances change and additional information becomes known, even from estimates not deemed critical. Our critical accounting estimates include the following:

​

Revenue Recognition

​

Revenue is measured as the amount of consideration expected to be received in exchange for transferring goods or providing service. Revenue from product and sold equipment is recognized when obligations under the terms of a contract with the customer are satisfied, which generally occurs with the transfer of the product or delivery of the equipment. Revenue from service and leased equipment is recognized when the services are provided, or the customer receives the benefit from the leased equipment, which is over time. Service revenue is recognized over time utilizing an input method and aligns with when the services are provided. Typically, revenue is recognized over time using costs incurred to date because the effort provided by the field selling and service organization represents services provided, which corresponds with the transfer of control. Revenue for leased equipment is accounted for under Topic 842 Leases and recognized on a straight-line basis over the length of the lease contract.

​

Our revenue policies do not provide for general rights of return. We record estimated reductions to revenue for customer programs and incentive offerings including pricing arrangements, promotions and other volume-based incentives based primarily on historical experience and anticipated performance over the contract period. Depending on market conditions, we may increase customer incentive offerings, which could reduce gross profit margins over the term of the incentive. We also record estimated reserves for product returns and credits based on specific circumstances and credit conditions. We record an allowance for uncollectible accounts based on our estimates of expected future credit losses.

​

The revenue standard can be applied to a portfolio of contracts with similar characteristics if it is reasonable that the effects of applying the standard at the portfolio would not be significantly different than applying the standard at the individual contract level. We apply the portfolio approach primarily within each operating segment by geographical region. Application of the portfolio approach was focused on those characteristics that have the most significant accounting consequences in terms of their effect on the timing of revenue recognition or the amount of revenue recognized. We determined the key criteria to assess with respect to the portfolio approach, including the related deliverables, the characteristics of the customers and the timing and transfer of goods and services, which most closely aligned within the operating segments. In addition, the accountability for the business operations, as well as the operational decisions on how to go to market and the product offerings, are performed at the operating segment level. For additional information on revenue recognition, refer to Note 18.

Litigation and Environmental Liabilities

​

Our business and operations are subject to extensive environmental laws and regulations governing, among other things, air emissions, wastewater discharges, the use and handling of hazardous substances, waste disposal and the investigation and remediation of soil and groundwater contamination. Some risk of environmental liability is inherent in our operations.

​

We record liabilities related to pending litigation, environmental claims and other contingencies when a loss is probable and can be reasonably estimated. Estimates used to record such liabilities are based on our best estimate of probable future costs. We record the amounts that represent the points in the range of estimates that we believe are most probable or the minimum amount when no amount within the range is a better estimate than any other amount. Potential insurance reimbursements generally are not anticipated in our accruals for environmental liabilities or other insured losses. Expected insurance proceeds are recorded as receivables when recovery is deemed certain. While the final resolution of litigation and environmental contingencies could result in amounts different than current accruals, and therefore have an impact on our consolidated financial results in a future reporting period, we believe the ultimate outcome will not have a significant impact on our consolidated financial position. For additional information on our commitments and contingencies, refer to Note 16.

​

Actuarially Determined Liabilities

​

Pension and Postretirement Healthcare Benefit Plans

​

The measurement of our pension and postretirement benefit obligations are dependent on a variety of assumptions determined by management and used by our actuaries. These assumptions affect the amount and timing of future pension contributions, benefit payments and expense or income recognized.

​

The significant assumptions used in developing the required estimates are the discount rates, expected returns on assets, projected salary and health care cost increases and mortality tables.

​

​

​

​

​

​

The effects of actual results differing from our assumptions, as well as changes in assumptions, are reflected in the unrecognized gains or losses and amortized into earnings in the future. Significant differences in actual experience or significant changes in assumptions may materially affect future pension and other postretirement obligations and income or expense. The unrecognized net losses on our U.S. qualified and non-qualified pension plans increased to $412 million as of December 31, 2022 from $397 million as of December 31, 2021 (both before tax), primarily due to lower actual return on assets partially offset by current year net actuarial gains.

Table of Contents

The effect of a decrease in the discount rate or decrease in the expected return on assets assumption as of December 31, 2022, on the December 31, 2022 defined benefit obligation and 2023 expense is shown below, assuming no changes in benefit levels. Expense amounts reflect the accounting for gains or losses as a component of other comprehensive income or expense and recognition of the impacts into earnings over time:

​

​

​

​

Our international pension obligations and underlying plan assets represent approximately one third of our global pension plans, with the majority of the amounts held in the U.K. and Eurozone countries. We use assumptions similar to our U.S. plan assumptions to measure our international pension obligations, however, the assumptions used vary by country based on specific local country requirements and information.

​

Refer to Note 17 for further discussion concerning our accounting policies, estimates, funded status, contributions and overall financial positions of our pension and postretirement plan obligations.

​

Self-Insurance

​

Globally we have insurance policies with varying deductible levels for property and casualty losses. We are insured for losses in excess of these deductibles, subject to policy terms and conditions and have recorded both a liability and an offsetting receivable for amounts in excess of these deductibles. We are self-insured for health care claims for eligible participating employees, subject to certain deductibles and limitations. We determine our liabilities for claims on an actuarial basis.

​

Income Taxes

​

Judgment is required to determine the annual effective income tax rate, deferred tax assets and liabilities, valuation allowances recorded against net deferred tax assets and uncertain tax positions.

​

Effective Income Tax Rate

​

Our effective income tax rate is based on annual income, statutory tax rates and tax planning available in the various jurisdictions in which we operate. Our annual effective income tax rate includes the impact of reserve provisions. We recognize the amount of tax benefit that is greater than 50% likely of being realized upon settlement with a taxing authority. We adjust these reserves in light of changing facts and circumstances.

​

Tax regulations require items to be included in our tax returns at different times than the items are reflected in our financial statements. As a result, the effective income tax rate reflected in our financial statements differs from that reported in our tax returns. Some of these differences are permanent, such as expenses that are not deductible on our tax return, and some are temporary differences, such as depreciation expense.

​

Deferred Tax Assets and Liabilities and Valuation Allowances

​

Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. Based on the evaluation of available evidence, both positive and negative, we recognize tax assets, such as net operating loss carryforwards and tax credit carryforwards, to the extent that realizing these benefits is considered to be more likely than not. Relevant factors in determining the realizability of deferred tax assets include historical results, sources of future taxable income, the expected timing of the reversal of temporary differences, tax planning strategies and the expiration dates of the various tax attributes.

Uncertain Tax Positions

​

A number of years may elapse before a particular tax matter, for which we have established a liability for uncertain tax position, is audited and finally resolved. The number of tax years with open tax audits varies depending on the tax jurisdiction. The Internal Revenue Service (“IRS”) has completed examinations of our U.S. federal income tax returns through 2016 and the years 2017 through 2020 are currently under audit. In addition to the U.S. federal examinations, we have ongoing audit activity in several U.S. state and foreign jurisdictions.

​

The tax positions we take are based on our interpretations of tax laws and regulations in the applicable federal, state and international jurisdictions. We believe our tax returns properly reflect the tax consequences of our operations, and our liabilities for uncertain tax positions are appropriate and sufficient for the positions taken. Because of the uncertainty of the final outcome of these examinations, we have estabilished a liability for potential reductions of tax benefits (including related interest and penalties) for amounts that do not meet the more-likely-than-not thresholds for recognition and measurement as required by authoritative guidance. The liability for uncertain tax positions is reviewed throughout the year, taking into account new legislation, regulations, case law and audit results. Settlement of any particular issue could result in offsets to other balance sheet accounts, cash payments or receipts and/or adjustments to tax expense. Liabilities for uncertain tax positions are presented in the Consolidated Balance Sheets within other non-current liabilities. Our gross liability for uncertain tax positions was $24.9 million and $25.1 million as of December 31, 2022 and 2021, respectively. For additional information on income taxes refer to Note 13.

​

Long-Lived Assets, Intangible Assets and Goodwill

​

Long-Lived and Amortizable Intangible Assets

​

Purchased long-lived and amortizable intangible assets not acquired as part of a business combination are recorded as of their acquisition date at cost, whereas long-lived and amortizable assets acquired as part of a business combination are recorded as of their acquisition date at their fair values based on the fair value requirements defined in U.S. GAAP. This requires us to make significant estimates and assumptions relating to the present value of its future cash flows, such as growth rates, royalty rates or discount rates.

​

We review our long-lived and amortizable intangible assets, the net value of which was $6.3 billion and $6.8 billion as of December 31, 2022 and 2021, respectively, for impairment when significant events or changes in business circumstances indicate that the carrying amount of the assets may not be recoverable. Such circumstances may include a significant decrease in the market price of an asset or asset group, a significant adverse change in the manner in which asset or asset groups are being used or history of operating or cash flow losses associated with the use of the asset or asset group. Impairment losses could occur when the carrying amount of an asset or asset group exceeds the anticipated future undiscounted cash flows expected to result from the use of the asset or asset group and its eventual disposition. The amount of the impairment loss to be recorded, if any, is calculated as the excess of the asset’s or assets group’s carrying amount over its estimated fair value.

​

We use the straight-line method to recognize amortization expense related to our amortizable intangible assets, including our customer relationships. We consider various factors when determining the appropriate method of amortization for our customer relationships, including projected sales data, customer attrition rates and length of key customer relationships.

​

Globally, we have a broad customer base. Our retention rate of significant customers has aligned with our acquisition assumptions, including the customer bases acquired from our Nalco, Anios, CID Lines and Purolite transactions, which make up the majority of our unamortized customer relationships. Our historical retention rates, coupled with our consistent track record of keeping long-term relationships with our customers, supports our expectation of consistent sales generation for the foreseeable future from the acquired customer bases. If our customer retention rates or other post-acquisition operational activities change materially, we would evaluate the financial impacts and significance of the events given rise to the change which could result in impairment of our customer relationship intangible assets, or absent an impairment, an acceleration of amortization expense.

​

In addition, we periodically reassess the estimated remaining useful lives of our long-lived and amortizable intangible assets. Changes to estimated useful lives would impact the amount of depreciation and amortization expense recorded in earnings. We have experienced no significant changes in the carrying amount or estimated remaining useful lives of our long-lived or amortizable intangible assets.

​

Goodwill and Indefinite Life Intangible Assets

​

Goodwill arises from our acquisitions and represents the excess of the fair value of the purchase consideration exchanged over the fair value of net assets acquired. We had total goodwill of $8.0 billion and $8.1 billion as of December 31, 2022 and 2021, respectively. We test our goodwill for impairment at the reporting unit level. Our reporting units are largely our operating segments. Following the acquisition of Purolite on December 1, 2021, our Life Sciences Operating Segment consists of the Purolite and Global Life Sciences Reporting Units. We assess goodwill for impairment on an annual basis during the second quarter. If circumstances change or events occur that demonstrate it is more likely than not that the carrying amount of a reporting unit exceeds its fair value, we complete an interim goodwill impairment assessment of that reporting unit prior to the next annual assessment. If the results of an annual or interim goodwill impairment assessment demonstrate the carrying amount of a reporting unit is greater than its fair value, we will recognize an impairment loss for the amount by which the reporting unit’s carrying amount exceeds its fair value, but not to exceed the carrying amount of goodwill assigned to that reporting unit.

​

32

Table of Contents

For our annual 2022 goodwill impairment assessment, we completed our impairment assessment for eleven of our twelve reporting units using discounted cash flow analyses that incorporated assumptions regarding future growth rates, terminal values and discount rates. Our goodwill impairment assessments for 2022 indicated the estimated fair values of each of these eleven reporting units exceeded the carrying amounts of the respective reporting units by a significant margin. Given the recent acquisition of Purolite, our annual goodwill impairment assessment of the Purolite Reporting Unit was qualitative in nature and considered information regarding its operations, financial performance and the macroeconomic environment. After weighting both positive and negative information, it is more likely than not that the fair value of the Purolite Reporting Unit exceeds its carrying amount. We evaluate the need to complete interim goodwill impairment assessments when significant events or changes in business circumstances indicate that it is more likely than not that the carrying amount of a reporting unit may be higher than its fair value. No events were noted during the second half of 2022 that required completion of an interim goodwill impairment assessment in the second half of 2022 for any of our twelve reporting units. There has been no impairment of goodwill in any of the periods presented.

​

The Nalco trade name is our only indefinite-lived intangible asset, which is tested for impairment on an annual basis during the second quarter. For our annual 2022 indefinite-lived intangible asset impairment assessment, we completed our impairment assessment of the Nalco trade name using the relief from royalty discounted cash flow method, which incorporates assumptions regarding future sales projections, royalty rates and discount rates. Our Nalco tradename impairment assessment for 2022 indicated the estimated fair value of the Nalco trade name exceeded its $1.2 billion carrying amount by a significant margin. No events were noted during the second half of 2022 that required completion of an interim impairment assessment of our Nalco trade name in the second half of 2022. There has been no impairment of the Nalco trade name intangible since it was acquired.

The percentage components of the year-over-year sales change are shown below:

​

​

Amounts do not necessarily sum due to rounding.

​

Cost of Sales (“COS”) and Gross Profit Margin (“Gross Margin”)

​

​

Our COS values and corresponding gross margin are shown above. Our gross margin is defined as sales less cost of sales divided by sales.

​

Table of Contents

Our reported gross margin was 37.8%, 40.2%, and 41.4% for 2022, 2021 and 2020, respectively. Our 2022, 2021 and 2020 reported gross margins were negatively impacted by special (gains) and charges of $69.9 million, $93.9 million, and $48.2 million, respectively. Special (gains) and charges items impacting COS are shown within the “Special (Gains) and Charges” table below.

​

Excluding the impact of special (gains) and charges and the 2021 impacts of the Purolite transaction, our 2022 adjusted gross margin was 38.2% compared against a 2021 adjusted gross margin of 40.9%. The decrease primarily reflected accelerating pricing that was more than offset by higher delivered product cost and unfavorable mix.

​

Excluding the impact of special (gains) and charges and the 2021 impacts of the Purolite transaction, our adjusted gross margin was 40.9% and 41.8% for 2021 and 2020, respectively. The decrease primarily reflected increased pricing and higher volumes which were more than offset by significantly higher delivered product costs and supply constraints.

​

Selling, General and Administrative Expenses (“SG&A”)

​

​

The decreased SG&A ratio (SG&A expenses as a percentage of reported net sales) comparing 2022 against 2021 was driven primarily by strong productivity including cost savings initiatives, partially offset by higher cost of compensation compared to last year. The decreased SG&A ratio (SG&A expenses as a percentage of reported net sales) comparing 2021 against 2020 was driven primarily by higher net sales, cost savings initiatives and reduction in bad debt, partially offset by higher variable compensation compared to last year.

​

Special (Gains) and Charges

​

Special (gains) and charges reported on the Consolidated Statements of Income included the following items:
