​ A Message from Ecolab’s Chairman and Chief Executive Officer ​

DEAR FELLOW STOCKHOLDER:

2025 was another record year for Ecolab. Thanks to our 48,000 associates, we delivered record sales, earnings per share, operating income margins and free cash flow by staying focused on what matters most: taking care of our customers and each other. This approach continues to drive strong, consistent growth across the Company.

Our team delivered strong performance across our businesses. Institutional & Specialty helped hospitality customers improve performance, address labor challenges and run efficiently. Global Water drove growth by delivering measurable value across commercial and industrial markets and advanced major opportunities in the fast-growing microelectronics and data center industries. Life Sciences delivered another strong year in biopharma as demand for high standards in contamination control and purification grew. And Pest Elimination drove strong growth as our digitally connected smart devices expanded their reach and delivered stronger outcomes for customers.

A major highlight of the year was welcoming Ovivo Electronics to the Ecolab family. Its world-leading ultrapure water technology strengthens our position across the microelectronics value chain and enables a best-in-class circular water offering for the fast-growing semiconductor market. With Ovivo, we now have the capability to serve all three industries fueling Artificial Intelligence’s (AI) growth: fabs, power systems and data centers.

Innovation continued to fuel our progress. We introduced smarter, more automated, more sustainable solutions across our portfolio — from advanced liquid cooling for data centers to AI-enabled cleaning systems in food and beverage facilities and Purolite resins for life-saving drug production. These solutions combine science-based expertise, data-driven insights, AI technologies and world-class service. This unique blend is what defines Ecolab, as we help millions of customers across 40 industries in 170 countries deliver better outcomes, higher performance and minimized environmental impact. It’s why we know what best-in-class looks like and how to help every customer reach it.

Our purpose-driven growth was also recognized globally. Ecolab was named one of the World’s Most Admired Companies by Fortune, ranking first in our industry for the 12th year. We also earned a rare Double-A rating by CDP, the world’s leading environmental rating organization, and were named on the Ethical Companies list by Ethisphere for the 20th consecutive year.

Our momentum in AI was also recognized on Fortune’s AIQ ranking, which identifies companies best prepared to lead in the age of AI. Ecolab’s number nine position reflects how we apply advanced analytics and AI technologies that help customers operate more efficiently, drive growth and conserve water and energy. We are helping shape the future of AI by combining deep technical expertise with purposeful innovation.

As we look ahead, the world is growing more complex, and our diverse portfolio positions us well to help customers stay ahead. We win by delivering better business outcomes, stronger operational performance and lower environmental impact, and we continue to raise the bar by investing in our people, technologies and One Ecolab growth strategy. The momentum we built this year gives us a strong foundation for the years ahead, and with a more connected organization, advanced portfolio and deeper customer partnerships, we are well positioned to keep delivering high performance for our customers and shareholders.

I look forward to sharing more detailed updates at our upcoming Annual Meeting of Stockholders. You can find details of the business to be addressed in our Notice of Annual Meeting and the Proxy Statement. I invite you to join the live webcast at 9:30 a.m., Central Time on May 7, 2026, and make your vote count. To attend, vote and submit questions, please visit www.virtualshareholdermeeting.com/ECL2026 and enter the 16-digit control number found in your Notice of Internet Availability of Proxy Materials, voting instruction form or proxy card.

I’m proud of what our team accomplished in 2025 and excited for what comes next. Thank you for your belief in Ecolab and in the work we do together. The best chapters of our story are ahead.

Christophe Beck

​ A Message from Ecolab’s
Lead Independent Director ​

DEAR FELLOW STOCKHOLDER:

As lead independent director, and on behalf of all Ecolab independent directors, I invite you to join the Company’s Annual Meeting of Stockholders on May 7, 2026, where you will hear important updates about Ecolab’s performance and have the opportunity to vote on the proposals included in the Notice of Annual Meeting and Proxy Statement.

As we reflect on 2025, I am pleased to share that Ecolab had another year of strong performance, disciplined execution and meaningful progress toward our long-term strategy. Ecolab continues to demonstrate resilience and innovation in a dynamic global environment, delivering results for customers while creating sustainable value for shareholders. Our performance this year once again reinforces the strength of our strategy, leadership and purpose-driven culture.

Ecolab delivered another year of strong returns while maintaining financial discipline. Together, we generated healthy top-line growth, improved margin performance and delivered strong free cash flow again in 2025. The company’s ability to consistently deliver these results — while continuing to invest in R&D, digital innovation, talent and growth opportunities — demonstrates focused leadership and a long-term mindset.

The Board remains confident in Ecolab’s financial strength and strategic direction. Maintaining a balanced and effective capital allocation framework remains a priority, including reinvesting to drive growth and announcing a 12% increase in our quarterly cash dividend — the 34th consecutive annual increase.

In May 2025, we welcomed Marion Gross to the Board as an independent director and member of the Compensation & Human Capital Management and the Safety, Health & Environment Committees. Marion’s extensive global business experience and deep knowledge of the global foodservice industry have already made her an exceptional asset to the Board.

In August 2025, we also welcomed Julie Whalen to the Board as an independent director and member of the Audit and Finance Committees. Julie’s comprehensive executive leadership experience and global perspective also had a significant impact.

In February 2026, Victoria Reich informed the Board that she would not stand for re-election at the Annual Meeting. Vicki has been a valued colleague and trusted advisor, consistently offering independent perspectives and her deep financial expertise and global leadership experience. We are deeply grateful for her 17 years of service, including seven years as Chair of the Audit Committee. We thank her for all the contributions she made to Ecolab and our team.

As Lead Independent Director, I remain committed to serving the best interests of Ecolab’s shareholders by ensuring our independent directors provide strong oversight and remain deeply engaged in the company’s most significant strategic and investment decisions. By continuing to prioritize engaging with investors, I’ve been able to incorporate their perspectives to help align Ecolab’s strategy with shareholder expectations. I’m also continuing to support ongoing Board refreshment by overseeing planned rotations of key Chair roles to bring fresh perspectives and ensure our governance remains rigorous, forward-looking and proactive.

As I look ahead, I remain confident in Ecolab’s ability to continue delivering strong performance and long-term value. I want to extend my sincere gratitude to our shareholders for their continued trust and support, which empower us to pursue our strategy with focus and ambition. I also am deeply appreciative of the Board’s steadfast leadership and their belief in Ecolab’s future. Their engagement and guidance strengthen our ability to advance our purpose, support our team and deliver sustainable growth for the years to come.

Innovation continued to fuel our progress.

These solutions combine science-based expertise, data-driven insights, AI technologies and world-class service. This unique blend is what defines Ecolab, as we help millions of customers across 40 industries in 170 countries deliver better outcomes, higher performance and minimized environmental impact.

​

​

Our team generated strong organic sales growth in Global Pest Elimination and Global Life Sciences, and good organic sales growth in Global Institutional & Specialty and Global Water.

​

Organic operating income grew by double digits, as strong value pricing and improved productivity were partially offset by investments in the business.

​

​

​

​

This solid performance reflected continued value pricing backed by leading customer value, strong new business wins, and breakthrough innovation that helps our customers improve their performance while also reducing their operating costs.

Proxy Summary

GROWING FAST, GROWING OUR IMPACT, GROWING OUR TEAM

Ecolab operates at the intersection of global macrotrends that directly influence long-term growth and risk, including public health, climate change, artificial intelligence and increasing pressure on water and energy resources. These dynamics are reshaping customer demand and investment decisions across industries. At Ecolab, they reinforce the strength and relevance of our business model.

By improving operational performance while reducing water and energy use, Ecolab delivers measurable economic value at scale. Our best-in-class, outcomes-driven partnership model integrates science-based solutions, digital insights, and service expertise to help customers lower costs, manage risk, and operate more efficiently across more than 40 industries. This performance advantage enables growth in a resource-constrained world and strengthens long-term customer relationships built on shared value.

Ecolab’s financial performance and positive impact are mutually reinforcing. Reduced water and energy use, improved productivity and smarter operations translate directly into customer value creation and sustained business growth. And as demand for AI and other resource-intensive technologies accelerates, water management is becoming a critical enabler of growth. Ecolab is well positioned to help customers navigate this transition with solutions that support resilience, performance and long-term value creation.

ENABLING CUSTOMERS TO ACHIEVE EXPONENTIAL OUTCOMES

Ecolab helps customers do more with less by improving performance, increasing operational efficiency and advancing sustainable impact. Through a powerful combination of science-based solutions, data-driven insights and world-class service, Ecolab delivers compounding outcomes, benefiting both customers and the communities in which they operate. This is eROI: the exponential return on investment customers achieve when stronger business outcomes, efficiency gains and environmental progress reinforce one another. As Ecolab grows, these outcomes scale, amplifying impact and value across industries.

Proxy Summary

OUR APPROACH

​ The Board uses a framework for key risks and opportunities considered to be most relevant to our long-term sustainability. This framework is informed by the 21 core metrics and disclosures outlined in the World Economic Forum (“WEF”) report entitled, Measuring Stakeholder Capitalism: Towards Common Metrics and Consistent Reporting of Sustainable Value Creation. Our framework aligns with the four themes in the WEF report — People, Planet, Prosperity and Principles of Governance. Responsibility for oversight of the metrics and disclosures included in the framework were assigned to the Board and its Committees through our Corporate Governance Principles, Committee Charters, and Core Agendas, based on the expertise of each Committee. Each year, the Board and its Committees review our Corporate Governance Principles, Committee Charters, and Core Agendas for alignment to the environmental stewardship, social responsibility, and sustainable business practices we aspire to achieve in accordance with this framework. ​ ​ ​

Board Oversight

Our Safety, Health and Environment (“SH&E”) Committee plays a prominent part in oversight, with responsibility for reviewing and overseeing our sustainability policies, programs, and practices that affect, or could affect, our employees, customers, stockholders and neighboring communities.

The SH&E Committee’s work is informed by our Sustainability Executive Advisory Team, led by the Senior Vice President and Chief Sustainability Officer. The Sustainability Executive Advisory Team monitors the risks and opportunities related to climate change and water stress, as well as our overall sustainability performance by collaborating with the global SH&E, supply chain, regulatory and corporate risk departments. The SH&E Committee receives regular updates from management on the Company’s sustainability goals and activities.

For example, the SH&E Committee’s sustainability reviews include: overall climate-related risks and progress towards Ecolab’s approved Science Based Climate Target aligned to a 1.5°C pathway to achieve net zero emissions by 2050, actions to implement the recommendations of the Task Force on Climate-related Financial Disclosures (“TCFD”), and water stewardship as a critical entry point to nature to inform and help guide our TCFD ambition.

Other committees of the Board, such as the Audit Committee, Governance Committee and the Compensation & Human Capital Management Committee follow a similar process for the sustainability and social responsibility topics over which they exercise oversight. The Board receives an annual presentation from members of the Sustainability Executive Advisory Team on our progress against our sustainability goals, and implementation of projects and related activities, which include management of water and climate-related issues, as appropriate. The Committees also report to the Board on their activities related to these topics. These activities contribute to the Board’s oversight of sustainability, climate- and water-related issues.

RECENT ACCOMPLISHMENTS

​ Environmental Stewardship ​

​ In 2025, management reported to the SH&E Committee on Ecolab’s progress toward its Positive Impact goals. This included performance related to improving water efficiency, reducing wastewater, mitigating water-related risks, advancing alternative energy sourcing and monitoring and managing nature and biodiversity risks as part of Ecolab’s water stewardship strategy. ​ ​ ​

Highlights of our efforts in 2025 include:

​

​

​

Reaffirming Ecolab’s commitment as a founding member of the Water Resilience Coalition (WRC), which has grown to 42 member companies representing more than $5 trillion in market capitalization. Ecolab also joined other participants in partnering with Water.org to launch Get Blue™, an initiative aimed at providing lasting access to safe water or sanitation for 200 million people by 2030.

​

​

​

​

​

Partnering with CDP to launch the Water Use Efficiency Index, a new benchmark designed to help companies measure, compare and improve operational water performance by providing sector- specific ranges for best-in-class efficiency and optimized targets.

​

​

​

​

Continuing leadership of the California Water Resilience Initiative (CWRI), convening leaders from business, government, philanthropy and civil society at the third annual California Water Resilience Forum to strengthen water resilience and address California’s projected water supply gap by 2030.

​

​

​

​

​

Supporting the scale-up of sustainable aviation fuel (SAF) through leadership in the Minnesota Sustainable Aviation Fuel Hub, applying Ecolab’s operational, water stewardship and renewable fuel expertise to help build an integrated SAF value chain and enable low-carbon aviation.

​

​

​

​

Making progress toward Positive Water Impact through achievement of Alliance for Water Stewardship (AWS) certification at 14 Ecolab facilities across Brazil, Chile, China, Mexico and the United States.

​

​

​

​

​

Deploying a geothermal field at Ecolab’s Innovation Center in Eagan, Minnesota, generating up to 56% of the campus’s energy demand from renewable sources and supporting progress toward the goal of halving operational greenhouse gas emissions by 2030 from a 2018 base year.

​

​ Social Responsibility ​

For over a century we have believed that doing the right thing, the right way, was good for business. This remains unchanged. More than ever, we believe that we will continue to grow fast by growing our net positive impact on people and the planet and by growing our teams. We believe that Ecolab’s long-term success, world-class innovation and best-in-class performance have benefited from a workplace that increasingly matches our end markets, and where individuals from all backgrounds are encouraged to reach their full potential. We believe in providing training and career development opportunities to all employees and in compensating and rewarding our employees equitably based on merit.

STOCKHOLDER OUTREACH AND ENGAGEMENT

We recognize the value of, and are committed to, engaging with our stockholders. We believe strong corporate governance includes proactive outreach and engagement with our stockholders on a regular basis and in a variety of settings throughout the year to better understand the issues that are important to them. These opportunities enable us to learn about matters important to our stockholders, driving improvements in our policies, communications and other areas. As part of our stockholder engagement program, our senior management team engaged with over 1,500 investors during 2025 on a variety of topics in a number of forums including quarterly earnings calls, investor and industry conferences, roadshows, analyst meetings, our biennial investor day, and individual corporate governance and sustainability-related discussions with stockholders.

​ PROPOSAL 1 — ELECTION OF DIRECTORS ​ ​ ​ ​ ​ The Board of Directors recommends a vote FOR the election of each of the 13 nominees named in this Proxy Statement to a one-year term ending in 2027. ​

DIRECTOR NOMINEES

The Governance Committee of our Board of Directors has nominated the 13 persons named on the following pages for election at the 2026 Annual Meeting. If elected, the nominees will hold office as directors from election until the next Annual Meeting of Stockholders or until their successors are elected and qualified or until their death, resignation or removal. All of the nominees are currently Company directors who were appointed by stockholders at the 2025 Annual Meeting, except for Ms. Whalen. Ms. Whalen was elected to the Board effective August 6, 2025, and assigned to the Audit Committee and the Finance Committee. Ms. Whalen was initially referred by an external search firm that was retained to identify potential candidates, recommended by the Governance Committee and interviewed by independent members of the Board. We would like to thank our valued colleague, Victoria J. Reich, who is not standing for re-election, for her service and valuable contributions to the Board.

DIRECTOR SELECTION PROCESS

Our Governance Committee leads all efforts related to Board refreshment. Each year, our Governance Committee reviews its Board membership qualifications and assesses the composition of the Board against these criteria, with a focus towards ensuring that the Board includes directors who possess the necessary backgrounds, experiences, and knowledge, offer a range of perspectives, and demonstrate independent judgment. The Governance Committee seeks to ensure that directors have a wide range of professional and personal skills that will support meaningful contributions to the strategic vision of the Company and oversight of business risks. We believe directors with such diversity of skills and experiences provide a deeper and better understanding of our customers and the business environments in which they operate, our end markets, and our associate experiences in the global workforce. The Governance Committee also considers possible conflicts of interest, and any other factors it determines appropriate to meeting the needs of the Board at that particular time. Accordingly, and as set forth in the Governance Committee charter and the Corporate Governance Principles, the Governance Committee will identify, evaluate and recommend, and the Board nominates, candidates for election or re-election to the Board, based on criteria including the following:

▪

the highest standards of personal and professional integrity

​

▪

the ability and judgment to serve the long-term interest of our stockholders

​

▪

relevant background, professional expertise and experience relevant to our business that will contribute to the overall effectiveness of the Board

​

▪

broad business and social perspective

​

▪

demonstrated independence of thought and judgment

​

▪

the ability to communicate openly with other directors and to meaningfully participate in the Board’s decision-making process

​

▪

commitment to serve on the Board for a period of time that ensures continuity and sufficient time to develop knowledge about our business

​

▪

willingness to devote appropriate time and effort to fulfilling the duties and responsibilities of a Board member

​

▪

the ability and willingness to objectively appraise the performance of management

​

▪

any other factors the Committee deems appropriate to meeting the needs of the Board at that particular time

​

Under our Corporate Governance Principles, the preferable size of the Board is between 11 and 15 members, in order to facilitate effective discussion and decision-making, adequate staffing of Board Committees, and a desired mix of diversified experience and background. Effective as of the Annual Meeting, the size of our Board of Directors will be 13 members.

TABLE OF CONTENTS

Corporate Governance and Board Matters

Our Board selected these 13 director nominees based on their diverse set of skills, perspective, experience, employment and background, which align with our business strategy and contribute to the effective oversight of Ecolab.

In nominating Mr. Doukeris, the Board considered his role as CEO of AB InBev and his service on the boards of two publicly traded companies that are majority owned and controlled by AB InBev. The Board recognizes that Mr. Doukeris’ other board service is an integral part of his responsibilities as CEO of AB InBev. Since joining the Board, Mr. Doukeris has been an active and engaged participant in Board and Committee meetings and is readily available to management for consultation. His extensive global business leadership, operational expertise, and deep industry experience relevant to Ecolab’s businesses are highly valued by the Company and the Board.

In nominating Mr. Zillmer, the Board has once again evaluated Mr. Zillmer’s continued service as the Non-Executive Chairman of CSX Corporation and his current role as CEO and board member of Aramark. Our Board recognizes that certain proxy advisors and stockholders have raised questions about the public company commitments for Mr. Zillmer. Mr. Zillmer has been highly engaged since joining our Board in 2006, and in 2025, attended 100% of the Board meetings and 100% of meetings of committees on which he serves. Mr. Zillmer is a fully active participant in our Board meetings and deliberations, is readily available for consultation with other independent directors, is a recognized leader among the Board for his responsiveness in between meetings, and serves an important role in the strong, independent oversight of management. Mr. Zillmer’s deep knowledge of the Company’s Institutional business, significant public company board experience and his proven leadership as CEO of three different companies over the course of his career are all highly valued by Ecolab and its Board.

Our Board strongly believes that Mr. Doukeris and Mr. Zillmer have demonstrated, and will continue to demonstrate, their ability to devote sufficient time and capacity needed to carry out the obligations as Board members for Ecolab including their respective Committee duties. After thorough consideration and assessment of their ongoing performance as an Ecolab Board member, the Board unanimously recommends the re-election of Mr. Doukeris and Mr. Zillmer at the Annual Meeting.

The Board has no reason to believe that any of the named nominees is not available or will not serve if elected. If, for any reason, any nominee becomes unavailable for election prior to our Annual Meeting, the proxies solicited by our Board of Directors will be voted for such substituted nominee as is selected by our Board of Directors, or our Board of Directors, at its option, may reduce the number of directors constituting the entire Board.

DIRECTOR INDEPENDENCE

Our Corporate Governance Principles provide that the Board will have a majority of independent directors who meet the criteria required for independence under the NYSE listing standards and our Director Independence Standards. To be considered independent, the Board must determine that a director has no material relationship with the Company (including its consolidated subsidiaries). Under these standards, the Board of Directors has affirmatively determined that each of our non-management director nominees is independent. The Board of Directors also previously affirmatively determined that Victoria J. Reich, who is not standing for re-election, is independent and, that Arthur J. Higgins, who did not stand for reelection at the 2025 Annual Meeting, was independent during the time that he served as a director.

The Board determined that Christophe Beck is not independent due to his current status as Chief Executive Officer. The Board also determined that each member of the Audit Committee and the Compensation & Human Capital Management Committee meets the heightened independence standards required for such committee members under the applicable NYSE listing and Securities and Exchange Commission (“SEC”) standards.

BOARD LEADERSHIP STRUCTURE

​		​	​	CHRISTOPHE BECK​	​	​		​	​	DAVID W. MACLENNAN​	​
			​	Chairman of the Board of Directors and Chief Executive Officer	​				​	Lead Independent Director	​

Our Board of Directors is led by Christophe Beck, our Chief Executive Officer and a member of the Board of Directors.

The Board of Directors strongly believes that independent board oversight is vital. As a result, under our corporate governance framework, our Lead Independent Director and independent directors have strong oversight of management and the Company’s governance.

As provided in our Corporate Governance Principles, the independent directors appoint a Lead Independent Director when (i) the offices of Chairman and Chief Executive Officer are held by the same person or (ii) when the Chairman is a different person than the Chief Executive Officer, but the Chairman has been determined by the Board of Directors not to be independent.

Responsibilities and powers of the Lead Independent Director, as enumerated in our Corporate Governance Principles, include:

▪

calling meetings of the independent directors;

​

▪

presiding over meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors, which occur at every regularly scheduled meeting of the Board;

​

▪

acting as a liaison between the Chairman and the independent directors;

​

▪

reviewing and approving meeting schedules to ensure there is sufficient time for discussion of all agenda items;

​

▪

reviewing and approving information sent to the directors;

​

▪

reviewing and approving meeting agendas and management participants at meetings of the Board; and

​

▪

engaging with stockholders in appropriate circumstances.

​

As stated in our Corporate Governance Principles, the Board believes it is in the best interests of our stockholders to have a flexible policy relating to the offices of Chairman and Chief Executive Officer and whether they are to be held by one person or two. Our Board evaluates its organizational structure every year, including its leadership. The Governance Committee leads this process, taking into account the results of the Board’s review of its own effectiveness, the performance and commitments of the Chairman and Lead Independent Director, and the current needs of the Board in overseeing the strategy and risks of the Company. The Governance Committee is also responsible for Board refreshment efforts and Committee assignments, ensuring that independent directors shape the Board’s membership and operation.

Mr. Beck was first appointed as Chairman in May 2022, and Mr. MacLennan was first elected as Lead Independent Director in May 2023. The Board continues to believe that at this time, combining our CEO and chairman offices under Mr. Beck, while maintaining the important role of the Lead Independent Director, is the most appropriate leadership structure for the Company and best serves the interests of our stockholders. In making this determination, the Board considered numerous factors, including:

▪

the benefits to the decision-making process with a leader who is both Chairman and Chief Executive Officer;

​

▪

the significant operating experience and qualifications of Mr. Beck, including 18 years at Ecolab where he held leadership roles within the Water, International, and Institutional businesses;

​

▪

the importance of deep Ecolab knowledge in exercising business judgment in leading the Board;

​

▪

the size and complexity of our business;

​

▪

the significant business experience and tenure of our independent directors; and

​

▪

the qualifications and role of our Lead Independent Director.

​

EXECUTIVE SESSIONS

The independent directors meet privately at every meeting of the Board and at each Committee of the Board. The independent directors also meet in executive session at other times during Board meetings at the request of any independent director.

​ Risk Management Processes and Procedures ​

The Board of Directors has established various processes and procedures for ongoing oversight of risk management. For example, annually, as a core agenda item of the full Board, management presents to the Board a comprehensive and detailed risk assessment of the Company after following a rigorous enterprise risk review and analysis.

ANNUAL ENTERPRISE RISK REVIEW & ANALYSIS

​

​

​

ANNUAL RISK ASSESSMENT

​

​

​

BOARD AND EXECUTIVE TEAM’S ONGOING REVIEW

​

​

​

IT SECURITY TRAINING & COMPLIANCE

​

▪ Conducted by internal audit services vice president ​ ▪ Consists of annual enterprise Assessment of Significant Business Risks that identifies company risks, including: ​ ▪ strategic ​ ▪ operational ​ ▪ financial ​ ▪ compliance-related ​ ▪ cybersecurity ​ ▪ Assesses risks, their likelihood, and the potential impact of their occurrence ​

​

​

​

▪ Management presents the results to the Board ​ ▪ Board approval is required for the Company’s annual strategic plan and major transactions ​

​

​

​

▪ Board reviews operating performance and strategic plan as appropriate ​ ▪ Review includes significant developments, such as: ​ ▪ acquisitions ​ ▪ financings ​ ▪ market developments ​ ▪ senior management succession ​ ▪ Independent, external third-party auditor’s findings are reviewed, relating to: ​ ▪ National Institute of Technology Cyber Security Framework and industry standards ​ ▪ cybersecurity peer benchmarking ​ ▪ periodic site security assessments ​

​

​

​

▪ Company conducts at least annually: ​ ▪ robust program for the entire company ​ ▪ awareness campaigns ​ ▪ testing and business resiliency training and drills with our supply chain ​

​

​ Strategic Risk Oversight ​

This review consists of our annual enterprise assessment of significant business risks, which provides the foundation for assessing the materiality of issues to our business and our stockholders. This comprehensive review is conducted using a survey tool designed to identify strategic, operational, financial, and compliance-related risks to the company. Risks are documented along with the likelihood and impact of their occurrence. The internal audit services vice president manages the process, and the results are presented to the Executive Management team and the Board of Directors.

This process identified key risks including:

▪

strategic risk (which relates to the Company properly defining and achieving its high-level goals and mission)

​

▪

operating risk (which relates to the effective and efficient use of resources and pursuit of opportunities)

​

These risks are monitored and managed by the full Board through the Board’s review of the Company’s operating performance and strategic plan. For example, at each of the Board’s regularly scheduled meetings throughout the year, management provided the Board presentations on the Company’s various business units as well as the Company’s performance. The Board also addresses significant developments as appropriate, such as significant acquisitions, important market developments, and senior management succession. Pursuant to the Board’s established monitoring procedures, Board approval is required for the Company’s annual strategic plan which is reported on by management at each Board meeting. Similarly, significant transactions (such as acquisitions and financings) are brought to the Board for approval.

​ Cybersecurity and AI Risk Oversight ​

Information security or cybersecurity is a strategic and operating risk for many companies. Since 2014, when the Ecolab cybersecurity program was established, the Company has continuously matured our program to proactively address cybersecurity trends and risks. Senior management provides in-depth reviews of cybersecurity matters to the Board directly and to the Audit Committee at least once a year in general. Cybersecurity is also considered in the detailed enterprise risk assessment presented to the Board each year. The Company has entered into, and plans to maintain, an information security risk insurance policy on commercially available terms.

BOARD AND COMMITTEE EVALUATIONS

Our Board continually seeks to improve its performance. A formal evaluation of the Board and its committees is conducted on an annual basis and is led by the Governance Committee. The format of the review is decided by the Governance Committee with input from directors, and it may vary from year to year depending on the needs of the Board. Each committee’s results are discussed by the respective committee, and the Board reviews the results of the Board and committee evaluations.

CODE OF CONDUCT

Our Code of Conduct is the foundation of our success and we are committed to upholding the highest legal and ethical standards, regardless of when and where we conduct business. Our Code of Conduct applies to our Chief Executive Officer, Chief Financial Officer, and our Corporate Controller, as well as to our directors and all other employees. Employees and directors receive training on the Code of Conduct annually and certify compliance. We will disclose future amendments to and any waiver that applies to any of our executive officers or a member of our Board on our website within four business days following the date of any such amendment or waiver.

POLITICAL CONTRIBUTIONS AND TRADE ASSOCIATIONS DISCLOSURES

The Company maintains a Political Contribution Policy, which is amended from time to time. The Political Contribution Policy, together with other Ecolab policies and procedures, guides Ecolab’s approach to political contributions. Among other things, the Political Contribution Policy provides that a report of contributions will be posted on Ecolab’s website semi-annually and that Ecolab will report annually on its website on its adherences to the Political Contribution Policy and related provisions in the Code of Conduct. The Governance Committee oversees the Political Contribution Policy, including reviewing the policy and a report of corporate political contributions annually. The Political Contribution Policy and current and archived political contributions are available at www.investor.ecolab.com/governance/political-contribution-reporting.

The Company also reports on its website its significant trade association memberships. We join trade associations that we believe will benefit our business and stockholders. A management committee reviews proposed and existing significant trade association memberships at least semi-annually to assess their effectiveness and to determine if continued membership is appropriate. In addition, the Governance Committee oversees significant trade association memberships and annually

COMMUNICATIONS WITH DIRECTORS

Our stakeholders and other interested parties, including our stockholders and employees, can send substantive communications to our Board using the following methods published on our website at www.investor.ecolab.com/governance/corporate-governance/contact-the-board:

​ »​ ​ ​ To correspond with the Board’s Lead Director, please complete and submit the online “Contact Lead Director” form ​ ​ ​ »​ ​ ​ To report potential issues regarding accounting, internal controls, and other auditing matters to the Board’s Audit Committee, please complete and submit the online “Contact Audit Committee” form ​

In addition to online communications, interested parties may direct correspondence to our Board of Directors, our Board Committees, to all independent directors as a group, or to individual directors, at our headquarters address referenced on page 90.

All substantive communications regarding governance matters or potential accounting, control, compliance, or auditing irregularities are promptly relayed or brought to the attention of the Lead Director or Chair of the Audit Committee following review by our management. Communications not requiring the substantive attention of our Board, such as employment inquiries, sales solicitations, questions about our products, and other such matters, are handled directly by our management. In such instances, we respond to the communicating party on behalf of the Board. Nonetheless, our management periodically updates the Board on all of the online communications received, whether or not our management believes they are substantive.

STOCKHOLDER RECOMMENDATIONS FOR DIRECTORS

Stockholders wishing to submit recommendations for director candidates for consideration by the Governance Committee must provide the following information in writing to the attention of the Corporate Secretary by certified or registered mail:

▪

the name, address, and biography of the candidate, and an indication of whether the candidate has expressed a willingness to serve;

​

▪

the name, address, and phone number of the stockholder or group of stockholders making the recommendation; and

​

▪

the number of shares of common stock beneficially owned by the stockholder or group of stockholders making the recommendation, the length of time held, and to the extent any stockholder is not a registered holder of such securities, proof of such ownership.

​

To be considered by the Governance Committee for the 2027 Annual Meeting, a director candidate recommendation must be received by the Corporate Secretary by January 7, 2027. The Governance Committee evaluates director candidates recommended by stockholders in the same way that it evaluates candidates recommended by its members, other members of the Board, or other persons.

DIRECTOR ATTENDANCE

There were five meetings of the Board of Directors during the year ended December 31, 2025. All directors attended at least 80% of the meetings held by the Board and Committees on which they served. Directors are expected to attend our Annual Meeting of Stockholders, absent unusual circumstances. All of the directors who continued to serve following the meeting attended last year’s Annual Meeting.

COMPENSATION & HUMAN CAPITAL MANAGEMENT COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The Compensation & Human Capital Management Committee is comprised of five non-employee, independent directors: Mses. Gross and McKibben, and Messrs. Green (Chair), MacLennan and Zillmer. No member of the Compensation & Human Capital Management Committee is or was formerly an officer or an employee of the Company or had any related person transaction required to be disclosed in which the Company was a participant during the last fiscal year. In addition, no executive officer of the Company serves on the Compensation & Human Capital Management Committee or board of directors of a company for which any of the Company’s directors serves as an executive officer.

RELATED PERSON TRANSACTIONS

The Governance Committee of the Board of Directors is responsible for reviewing, approving, or ratifying transactions and proposed transactions in excess of $120,000 with the Company’s executive officers or directors, including their immediate family members, or any greater than 5% stockholder known to us. The Company has written practices and procedures for identifying transactions with related persons. The Governance Committee considers the related person’s relationship to the Company and interest in the transaction; the material facts of the transaction, including the proposed aggregate value of such transaction; the benefits to the Company of the proposed related-person transaction; if applicable, the availability of other sources of comparable products or services; an assessment of whether the proposed related person transaction is on terms that are comparable to the terms available to an unrelated third party or to employees; and such other factors and information as the Governance Committee may deem appropriate. The Governance Committee determined that there were no such transactions with related persons since the beginning of 2025, nor any currently anticipated transactions.

DIRECTOR COMPENSATION FOR 2025

During 2025, members of the Board of Directors who were not employees of the Company were entitled to receive the following compensation:

​	ADDITIONAL SUPPLEMENTAL RETAINERS FOR SELECT BOARD SERVICE ($)								​
​	Lead Director	​	​	​	​	​	40,000	​	​
​	Committee Assignments:	​	​	​					​
​	▪ Audit Committee Chair ​	​	​	​	​	​	25,000	​	​
​	▪ Compensation & Human Capital Management Committee Chair ​	​	​	​	​	​	20,000	​	​
​	▪ Finance Committee Chair ​	​	​	​	​	​	20,000	​	​
​	▪ Governance Committee Chair ​	​	​	​	​	​	20,000	​	​
​	▪ Safety, Health & Environment Committee Chair ​	​	​	​	​	​	20,000	​	​
​	▪ Audit Committee Member ​	​	​	​	​	​	10,000	​	​

​

The base annual compensation of $315,000 per year, excluding lead director and committee retainers, was within the median range of our competitive market. For director compensation, we define our competitive market as a peer group of 21 companies we use for compensation benchmarking and the median range as within 10% of the median for total annual director compensation. The companies comprising our peer group are the same as the executive compensation peer group and are set forth under the heading “Compensation Benchmarking” found under the Compensation Discussion and Analysis of this Proxy Statement at page 47.

Equity awards are granted to our non-employee directors under the 2001 Non-Employee Director Stock Option and Deferred Compensation Plan (the “2001 Plan”). Under the 2001 Plan, the aggregate grant date fair value of awards denominated in shares that may be made to any non-employee director during any calendar year may not exceed $800,000, excluding such awards made at the election of a director to defer the receipt of cash compensation otherwise payable for services as a director.

Director stock option awards are granted after the Annual Meeting of Stockholders and vest in 25% installments three, six and nine months, respectively, after the grant date, and as to the last 25%, (a) twelve months after the grant date for director stock option awards granted prior to December 4, 2025, or (b) the earlier of twelve months after the grant date or the Company’s next annual meeting date for director stock option awards granted on or after December 4, 2025. A director appointed after the annual meeting will receive a pro rata grant after the next annual meeting based on the number of days in service. Stock unit awards are credited to a director’s deferred stock unit account in 25% installments on a quarterly basis, are prorated for any director who serves for only part of a quarter, based on the number of days in service, and are paid in shares of our Common Stock following cessation of Board service pursuant to the director’s distribution election for deferred stock units under the 2001 Plan. Directors are credited with dividend equivalents on their stock units, which are automatically converted into additional full or fractional stock units.

The 2001 Plan also permits non-employee directors to defer some or all of their cash retainers into accounts that provide for either interest at market rates or an investment in Company stock units, which include the right to dividend equivalents as

​ 34    CONSISTENT HIGH PERFORMANCE ​ ​ ​ ​

TABLE OF CONTENTS​​

Corporate Governance and Board Matters

described above. Upon cessation of Board service, deferred amounts are paid in a lump sum or installments over a maximum of ten years as elected by the director, with payments from the interest-bearing account made in cash and payments from the stock unit account made in shares of our Common Stock.

All reasonable travel and other expenses incurred by directors on behalf of Ecolab were reimbursed. From time to time, spouses may be invited to attend certain meetings at the request of the Board. If Spouses are invited to attend meetings, we provide transportation or cover the cost of the additional travel including tax gross-up.

​	STOCK RETENTION AND OWNERSHIP GUIDELINES​				​	​		​
​	Our stock retention and ownership guidelines encourage our directors to accumulate a significant ownership stake in the Company for alignment with long-term stockholder interests. Our guidelines provide that our directors own Company stock with a market value of at least five times the annual retainer.	​	​

Until the stock ownership guideline is met, a director should retain 100% of the net shares received from stock option exercises. Shares owned outright, legally or beneficially, by a director or his or her immediate family members residing in the same household and deferred stock units held under the director’s deferral plan count towards the guidelines. Unexercised stock options do not count towards the guidelines. Each of our directors is currently in compliance with our guidelines by either having achieved the ownership guideline or, if the guideline is not yet achieved, by retaining 100% of all net shares received from any stock option exercises.

Our directors may not pledge shares or enter into any risk hedging arrangements with respect to Company stock.

The dollar amount of retainer and fees deferred by applicable directors during 2025 is as follows: Mr. Althoff, $131,033; Ms. Ballard, $135,000; Mr. Green, $145,000; Mr. Higgins, $44,299; and Mr. MacLennan, $92,500.

The number of stock units was determined based on the average of the high and low share price of the Company’s common stock on the date of grant. The aggregate number of stock units held by each non-employee director is set forth under footnote (3) to the “Executive Officers and Directors” table in the Security Ownership section on page 37.

CHANGES EFFECTIVE IN 2026

The Compensation & HCM Committee reviews our compensation program for non-employee directors annually; however, it is our general practice to consider adjustments to our program changes less frequently than annually. Based upon the recommendation of the Compensation Committee’s independent consultant, Frederic W. Cook & Co., Inc. (“FW Cook”), we made the following changes effective as of January 1, 2026:

▪

Increased the annual cash retainer from $125,000 to $135,000;

​

▪

Increased the annual deferred stock unit award from $135,000 to $145,000;

​

▪

Increased the supplemental retainer for the Lead Director from $40,000 to $45,000;

​

▪

Increased the supplemental retainer for the Audit Committee chair from $25,000 to $30,000; and

​

▪

Increased the supplemental retainer for the other committee chairs from $20,000 to $25,000.

​

We retained all of the other components of our non-employee director compensation program, including the annual stock option grant of $55,000 and the retainer of the Audit Committee members, without change. The changes to the annual retainer and stock unit awards increase total annual compensation from $315,000 per year to $335,000 per year, excluding committee retainers, which is within the median range of our competitive market as previously defined at page 34 of this Proxy Statement. Prior to these changes, the compensation amounts under the program were last changed effective as of January 1, 2024.

​ Executive Compensation ​

​ PROPOSAL 2 — ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION​ ​ ​ ​ ​ ​ The Board of Directors recommends that you vote FOR approval of the compensation of Ecolab’s named executive officers as described in the Compensation Discussion and Analysis and the compensation tables pursuant to the compensation disclosure rules of the SEC. ​

At the 2023 Annual Meeting, we provided our stockholders with an advisory vote regarding how frequently the Company will conduct future stockholder advisory votes to approve the compensation of our named executive officers. More than 98% of the total votes cast voted in favor of an annual vote, consistent with the recommendation of the Board. Based on these results, the Board has determined to continue to hold an advisory vote on the compensation of our named executive officers on an annual basis.

​ ​ ​ Our compensation programs encourage executive decision-making that is aligned with the long-term interests of our stockholders. ​ ​ ​ ​ ​ We tie a significant portion of pay to Company performance over a multi-year period. ​

As discussed in the Compensation Discussion and Analysis contained in this Proxy Statement, we believe that our executive compensation program for 2025 was reasonable and appropriate, with payout results justified by the performance of the Company. Our compensation program is the result of a carefully considered approach, including input and advice from the Compensation & Human Capital Management Committee’s independent compensation consultant and input of stockholders through the Company’s stockholder engagement efforts.

The Company is presenting this proposal pursuant to Section 14A of the Exchange Act, which gives you as a stockholder the opportunity to endorse or not endorse our executive pay program through an advisory vote for or against the following resolution:

“RESOLVED, that the stockholders approve, on an advisory basis, the compensation of our named executive officers, as disclosed in the Company’s Proxy Statement for the 2026 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the compensation tables, and the related disclosure contained in the Proxy Statement.”

The Board of Directors encourages stockholders to approve the compensation program for our named executive officers by voting FOR the above resolution. Because your vote is advisory, it will not be binding upon the Board of Directors. However, as it has done historically, the Compensation & Human Capital Management Committee will take into account the outcome of the vote when considering future executive compensation arrangements. Our next advisory vote on the compensation program for our named executive officers will occur at our 2027 Annual Meeting.

​ ​ ​ The Board of Directors recommends that you vote FOR approval of the compensation of Ecolab’s named executive officers as described in the Compensation Discussion and Analysis and the compensation tables pursuant to the compensation disclosure rules of the SEC. Unless a contrary choice is specified, proxies solicited by our Board of Directors will be voted FOR the proposal. ​

​

In 2025, Ecolab delivered record sales, operating income margin, free cash flow, and adjusted diluted earnings per share (hereinafter “adjusted EPS” or “adjusted diluted EPS”). Organic sales grew 3% and organic operating income margin expanded by 150 basis points, resulting in 13% growth in adjusted diluted EPS. This performance was fueled by the significant total value the Ecolab team and our technologies delivered to our customers. We also continued to invest in breakthrough innovation, new digital capabilities, and developing our sales and service expertise to further strengthen Ecolab’s competitive position, enhance our customer value proposition, and expand future growth opportunities.

​ Incentive Compensation Highlights ​

The Company’s compensation programs enable us to attract and retain the leadership talent that is necessary to successfully manage our strong earnings growth and return on invested capital objectives, while balancing essential investment in our businesses to achieve attractive, long-term shareholder returns.

As a result of our 2025 performance, the payout under our Management Incentive Plan (“MIP”) versus our pre-established adjusted EPS goal was achieved at 137% of target as illustrated below.

In addition, the enterprise goal for Mr. Brown and Ms. King (which includes both adjusted EPS and commercial average components) was achieved at 113% of target. The business unit goal for Mr. Cook (which includes business unit sales and operating income components) was achieved at 138% of target. The individual goals for Mr. Kirkland and Ms. King were achieved at 113%. The Growth & Impact modifier was achieved at 8%.

Performance under our 2023-2025 performance-based restricted stock unit (PBRSU) grant cycle exceeded our pre-established adjusted ROIC performance goal and payout of shares was at 100% of target, as illustrated below:

​ Say-on-Pay Results and Stockholder Outreach ​

We recognize the value of and are committed to engaging with our stockholders, including on executive compensation matters. During 2025, we contacted stockholders holding approximately 52% of our shares and held meetings with stockholders holding approximately 41% of our shares. Our Lead Independent Director attended several of these meetings, having conversations with stockholders representing approximately 34% of our shares.

We consistently found that stockholders supported the current structure of our compensation program. At the 2025 Annual Meeting, the advisory vote on the compensation of our NEOs was approved with the support of 90% of the total votes cast. The Compensation & HCM Committee considered this favorable stockholder support in deciding to retain the overall structure and philosophy of our compensation plans and programs in 2025.

COMPENSATION PHILOSOPHY AND PROCESS

​ Our Compensation Philosophy ​

Ecolab’s executive compensation program is designed to:

​ ​ ​ Support our corporate vision and long-term financial objectives ​ ​ ​ ​ ​ Communicate the importance of business results ​ ​ ​ ​ ​ Retain and motivate executives who are critical to our success ​ ​ ​ ​ ​ Reward executives for contributions at a level reflecting our performance ​

Our program as a whole, as well as each element, is designed to be market-competitive in order to attract, motivate, and retain our executives in a manner that is in the best interests of our stockholders. The program is further designed to:

▪

reinforce and complement ethical and sustainable management practices,

​

▪

promote sound risk management, and

​

▪

align management interests (such as sustainable long-term growth) with those of our stockholders.

​

Our philosophy is to position base salary, annual cash incentives, and long-term equity incentives in the median range of our competitive market, adjusted for the Company’s size, while actual compensation may be targeted below or above the median range based on executive experience, performance, scope of responsibilities, and other relevant factors. We also design annual cash incentives such that they pay out at a level commensurate with the Company’s performance based on adjusted EPS goals developed with consideration of EPS growth in the Standard & Poor’s 500 (“S&P 500”), with lower than median compensation for lower than competitive market performance and higher than median compensation for higher than competitive market performance. This approach motivates executives without incentivizing inappropriate risk-taking to achieve payouts, as we believe the Company’s growth prospects are generally at least as favorable as the S&P 500’s average. The 2025 TDC opportunities for all our NEOs were positioned within their respective market median range.

​ Roles & Responsibilities in the Compensation Process ​

The Compensation & HCM Committee oversees the design and administration of our executive compensation program as discussed in the Corporate Governance section of this Proxy Statement. The Compensation & HCM Committee is advised by an independent compensation consultant, FW Cook.

​ 46    CONSISTENT HIGH PERFORMANCE ​ ​ ​ ​

TABLE OF CONTENTS​

Executive Compensation

As requested from time to time, FW Cook:

▪

provides the Compensation & HCM Committee with market data regarding various components of executive and director compensation,

​

▪

reviews the methodology on which compensation is based and designed, and

​

▪

informs the Compensation & HCM Committee of market trends in executive and director compensation.

​

FW Cook provides no services for us other than those performed on behalf of the Compensation & HCM Committee. The Compensation & HCM Committee has considered the independence of FW Cook in light of SEC rules and NYSE listing standards. In connection with this process, the Compensation & HCM Committee concluded that the work performed by FW Cook and its senior advisor involved in the engagement did not raise any conflict of interest during 2025.

For our NEOs, the Compensation & HCM Committee reviewed and approved all elements of 2025 compensation, considering recommendations from our CEO (other than with respect to his own compensation), as well as competitive market guidance and feedback provided by FW Cook, information from our human resources staff regarding individual performance, time in position, and internal pay comparisons. With respect to our CEO, the Compensation & HCM Committee also considered the Board’s performance assessment of the CEO. Recommendations with respect to the compensation of our CEO are not shared with our CEO until approved by the Compensation & HCM Committee.

The Committee may form and delegate authority to subcommittees as it deems appropriate. To the extent permitted by applicable law, the Committee may also delegate to one or more executive officers of the Company the authority, within guidelines established by the Committee, to approve equity compensation awards under established equity compensation plans of the Company to employees other than officers of the Company including those subject to Section 16 of the Exchange Act. The Committee may also delegate any non-discretionary administrative authority under Company compensation and benefit plans consistent with any limitations specified in the applicable plans.

​ Compensation Benchmarking ​

For benchmarking purposes, we define our competitive market for compensation data to be a simple average of median compensation from a 21-company peer group and a size-adjusted median of general industry data from third-party surveys in which we participate.

The peer group and benchmarking methodology is approved by the Compensation & HCM Committee in the spring of each year based on input from FW Cook and management. FW Cook presents an objective selection methodology as follows:

​

1

​

​

​

Focus on companies in the S&P 500 Materials, Industrials, Life Sciences, Tools & Services, or Consumer Staples sectors

​

​

​

2

​

​

​

Screen for companies with annual revenues of 1∕4 to 4x the annual revenues of our Company

​

​

3

​

​

​

Further screen for companies within a reasonable size range in various other measures, such as: ▪ EBITDA ​ ▪ total assets ​ ▪ total equity ​ ▪ total employees ​ ▪ market capitalization ​

​

​

​

4

​

​

​

Identify companies that meet several other criteria, such as: ▪ significant international operations ​ ▪ including Ecolab as a compensation benchmarking peer ​ ▪ business-to-business focus ​

​

Following this review process in 2025, the Compensation & HCM Committee determined to make no changes to the 21-company peer group for 2025.

To align pay levels for NEOs with the Company’s performance, our pay mix places the greatest emphasis on performance-based incentives. As summarized below, 91% of our CEO’s 2025 target TDC and 80% of the average target TDC of the remaining NEOs were performance-based. The greater emphasis on performance-based compensation for the CEO is designed to reward him for driving company performance and creating long-term shareholder value given his position and responsibilities in the Company.

Executive Compensation

​ Base Salaries ​

With limited exceptions, such as promotions and executive transitions, the Compensation & HCM Committee reviews base salaries for our NEOs and other executives annually in February, with any adjustments to be effective in April of the current fiscal year. Adjustments are based on:

▪

changes in our competitive market,

​

▪

changes in scope of responsibility,

​

▪

individual performance, and

​

▪

time in position.

​

Our philosophy is to pay base salaries that are within the median range of our size-adjusted competitive market. When an executive officer is new to his or her position, his or her initial base salary will typically be at the low end of the median range, but with strong performance, his or her base salary will be increased over time. The 2025 base salary levels for all our NEOs were within the median range. The merit increases for Mr. Beck, Mr. Kirkland and Mr. Brown were in line with the principles and metrics used to deliver the Company’s U.S. salary increases broadly. Consistent with our practice, Mr. Cook received a larger merit increase in 2025 to move his base salary towards the market median following his promotion to his current position in 2023.

The 2025 annualized base salary rates in effect for our NEOs before and after increases are summarized below:

​

​ Annual Cash Incentives ​

The Company maintains an annual cash incentive program for executives referred to as the Management Incentive Plan, or MIP. The Compensation & HCM Committee establishes goals under the MIP at its February meeting. In February 2026, the Compensation & HCM Committee reviewed the performance of the NEOs and other executives to determine the 2025 MIP award payments earned in 2025 (which were paid in March 2026).

TARGET AWARD OPPORTUNITIES

Under the MIP, we establish annual target award opportunities expressed as a percentage of base salary paid during the year. Our annual cash incentive targets are generally set within the median range relative to our competitive market for each position, and the annual cash incentive plan is structured so that lower performance results in below-market payouts and superior performance drives payouts above the median range. The Compensation & HCM Committee modestly increased the MIP target award (as a percentage of base salary) for Mr. Beck and Mr. Cook to maintain alignment with market. The 2025 MIP target awards for Mr. Kirkland and Mr. Brown (as a percentage of base salary) remained the same as 2024. Ms. King commenced employment with Ecolab on January 6, 2025, and her 2025 MIP target award was set in her employment offer. The 2025 target award opportunities for the NEOs are set forth below:

OVERVIEW OF PERFORMANCE MEASURES

Under the MIP, we use a mix of overall corporate performance, business unit performance, individual performance, and impact measures to foster cross-divisional cooperation and to assure that executives have a reasonable measure of control over the factors that affect their awards. This performance measure mix varies by executive position. Payout opportunities range from 0% to 200% of each NEO’s target award opportunity.

Represents Ms. King’s MIP performance measures from June 1 to December 31, 2025, reflecting her executive officer appointment. Prior to June 1, 2025, the MIP performance measures for Ms. King include the Adjusted EPS goal (weighted 30%), the Enterprise goal (weighted 50%), and her individual goals (weighted 20%), and the Growth & Impact modifier did not apply.

​

▪

ADJUSTED EPS GOAL: As in prior years, the primary measure of overall corporate performance under the 2025 MIP was adjusted diluted EPS. We believe that adjusted diluted EPS is a better measure of the Company’s underlying business performance than reported diluted EPS because it provides greater transparency with respect to our results of operations, which is more useful for period-to-period comparisons of results. We also use adjusted EPS internally in making financial and operational decisions and evaluating our own performance. Adjusted diluted EPS was a performance measure in each of our NEO’s 2025 MIP opportunities, including our NEOs who manage particular business units, because it reinforces our “One Ecolab” strategy and fosters cross-divisional cooperation.

​

▪

ENTERPRISE GOAL: For Mr. Brown, whose role has a significant impact on the performance of all the Company’s businesses, and a direct impact on the Company’s ability to meet business sales and operating income targets, the 2025 MIP was also based on an enterprise performance goal. This goal is intended to incentivize and reward the NEO based on both the financial performance of Ecolab’s various businesses and overall Ecolab performance. Prior to June 1, 2025, Ms. King’s 2025 MIP was also based in part on the enterprise performance goal. The enterprise goal is based 60% on a commercial average payout, which represents the aggregate payouts achieved for business unit sales and/or operating income goals to all employees in the commercial organization relative to the aggregate target business unit payouts. The remaining 40% of the enterprise goal is based on the company-wide adjusted EPS performance.

​

▪

BUSINESS UNIT GOAL: For Mr. Cook, who led the Global Institutional Group, the 2025 MIP incorporated goals for his business unit, comprised of year-over-year sales growth and operating income growth with equal weighting. These goals are designed to incentivize and reward the performance of the business unit for which he is responsible.

​

▪

INDIVIDUAL GOALS: For two of our NEOs who hold staff positions — Mr. Kirkland and Ms. King, we utilize strategic corporate initiatives and goals, as detailed beginning on page 52, which may include financial, human capital and/or leadership indicators, as a part of the individual performance measures to promote sustained company success.

​

▪

GROWTH & IMPACT MODIFIER: We apply a Growth & Impact modifier to the MIP for officers. The modifier is based on reducing water intensity across our operations and demonstrating progress toward team engagement, employee retention and development metrics. This modifier recognizes that delivering a net positive impact for our associates and operations, with our customers and in our communities, drives performance and innovation, and enables accelerated growth.

​

In measuring the enterprise and business unit goals and determining payouts to executives under the MIP, sales and operating income performance measures are recorded at fixed currency rates of foreign exchange. Business unit performance goal

results may also be adjusted for special gains and charges, as well as certain other exceptional items, such as the results of certain businesses acquired during the year and certain strategic initiatives not contemplated by the annual business plan when original goals were established. We include within special gains and charges items that we believe can significantly affect the period-over-period assessment of operating results and that do not necessarily reflect costs and/or income associated with historical trends and future operating results, as more fully identified on pages 33 to 36 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

PERFORMANCE MEASURES AND ACHIEVEMENT — ADJUSTED EPS

In establishing the adjusted EPS goal for 2025, we took into consideration our prior year results, overall economic and market trends, S&P 500 companies’ performance expectations, and our anticipated business opportunities, investment requirements, and the competitive situation. The minimum adjusted EPS level was set at $6.85, higher than our actual adjusted EPS of $6.65 for 2024. For 2025, the adjusted EPS goals were as follows:

​	PERCENTAGE OF THE TARGET AWARD OPPORTUNITY	​	​	​	ADJUSTED EPS ($)				​
​	40% (Minimum Level)	​	​	​	​	​	6.85	​	​
​	100% (Target Level)	​	​	​	​	​	7.27	​	​
​	140% (140% Level)	​	​	​	​	​	7.55	​	​
​	200% (Maximum Level)	​	​	​	​	​	≥7.95	​	​

Payouts for results between performance levels are interpolated on a straight-line basis. Actual 2025 adjusted EPS was $7.53, resulting in a 137% payout with respect to this performance goal.

PERFORMANCE MEASURES AND ACHIEVEMENT — ENTERPRISE GOAL

30% of Mr. Brown’s 2025 MIP target, and prior to June 1, 2025, 50% of Ms. King’s 2025 MIP target were linked to our enterprise goal. The enterprise performance goal is intended to incentivize and reward Mr. Brown and Ms. King based on the financial performance of Ecolab’s various businesses and overall Company performance.

The enterprise goal is comprised of 60% commercial average payout for sales and/or operating income performance across the Company’s business units and 40% adjusted EPS performance. Because this measure includes aggregate performance across all business units, there is no threshold payout level; however, the maximum payout of 200% of target continues to apply.

The commercial average performance was measured at 97%, and adjusted EPS was achieved at 137%, resulting in an enterprise goal payout of 113% of target.

PERFORMANCE MEASURES AND ACHIEVEMENT — BUSINESS UNIT

In his role as Executive Vice President and President — Institutional Group, 70% of Mr. Cook’s 2025 MIP target was linked to goals for the Global Institutional Group business unit. Performance against his business unit goal is measured at 50% on year-over-year sales growth and 50% on year-over-year operating income growth.

Sales and operating income performance for the Global Institutional Group were achieved at 114% and 162%, respectively, resulting in a business unit goal payout of 138% of target.

PERFORMANCE MEASURES AND ACHIEVEMENT — INDIVIDUAL

For two of our NEOs who hold staff positions — Mr. Kirkland (Chief Financial Officer) and Ms. King (Executive Vice President, Human Resources) — 30% of their MIP annual cash incentive targets are linked to individual performance goals. This individual component of staff position awards under the MIP is set at 30% of the performance measure mix for annual cash incentives, so that achievement of these goals is a component of the award but remains balanced against achievement of corporate and, as applicable, enterprise performance goals. Prior to June 1, 2025, 20% of Ms. King’s 2025 MIP was linked to her individual performance goals.

The 2025 individual performance objectives for these officers are:

▪

specific,

​

▪

qualitative,

​

▪

achievable with significant effort, and

​

▪

if achieved, provide meaningful benefit to the Company.

PERFORMANCE MEASURES AND ACHIEVEMENT — GROWTH & IMPACT MODIFIER

In assessing the achievement of the Growth & Impact modifier for 2025, we considered the necessary steps to achieve our aspirations for reducing water use intensity across our operations and advancing our team engagement, retention and development. This modifier recognizes that delivering a net positive impact for our associates and operations, with our customers and in our communities, drives performance and innovation, and enables growth. The Growth & Impact modifier increases MIP payout by 2%, 5%, 8%, or 10%, or reduces MIP payout by 10%, based on performance in Growth & Impact areas as assessed by the Compensation & HCM Committee.

For 2025, the Compensation & HCM Committee determined that the Growth & Impact modifier should increase the MIP payout by 8%, subject to the 200% payout cap under the MIP. This payout level is aligned with exceeding the targets set for reduction in water intensity across our operations and performance against applicable benchmarks for team engagement, retention and development. The assessment of performance for the Growth & Impact modifier is made for all officers in the aggregate, and not on an individual basis. Performance indicators may be adjusted for acquisitions and divestitures that have a material impact.

TABLE OF CONTENTS​

Executive Compensation

The Compensation & HCM Committee may increase or decrease an NEO’s payout, with input from the CEO (other than as to his own award), based on the individual performance of the NEO. The Compensation & HCM Committee has not historically made such discretionary adjustments to an NEO’s payout, except in new hire situations in which the amount of an executive’s annual cash incentive is guaranteed, or other exceptional circumstances. The 2025 annual cash incentive payouts were made in accordance with the overall corporate results and enterprise, business unit and individual performance results established for the NEOs without adjustment. Additionally, none of the executives had a guaranteed cash incentive for 2025.

​ Long-Term Equity Incentives ​

The Compensation & HCM Committee made annual grants of long-term equity incentives to our NEOs in December 2025, consistent with its past practice of granting these incentives at its regularly scheduled December meeting. Our philosophy is to grant long-term incentives that are within the median range of our size-adjusted competitive market. In 2025, our NEOs received long-term incentives near or within the median range. The table below sets forth each NEO’s annual long-term incentive award value at target, as well as the number of target 2026 – 2028 PBRSUs and stock options granted in December 2025.

Represents a long-term incentive grant of $1.0 million target award value in lieu of the 2024 December long-term incentive grant as Ms. King commenced employment on January 6, 2025. Consistent with our annual grant practice, this grant includes 60% PBRSUs and 40% stock options. The PBRSUs have the same vesting terms and performance goals as the PBRSUs for the 2025 – 2027 performance period approved by the Compensation & HCM Committee in December 2024, except that they are not subject to the relative TSR modifier. The number of target PBRSUs was determined based on a historical average share price. The number of stock options was determined based on a historical average share price and the binomial stock option valuation method.

​

(b)

Represents a restricted stock unit award of $1.2 million to buy out the equity and other benefits that Ms. King forfeited upon termination of her prior employment to join Ecolab.

TABLE OF CONTENTS​

Executive Compensation

The material terms of the 2025 annual long-term equity incentive awards are as follows:

​	AWARD TYPE	​	​	​	MATERIAL TERMS	​
​	PBRSUs	​	​	​	▪ Cliff-vests after three-year performance period, subject to attainment of three-year organic ROIC goals and modification based on relative TSR ​ ▪ Target three-year organic ROIC goals were set at levels that would require significant year-over-year organic growth and focus our management team on our long-term fundamentals; the relative TSR modifier balances achievement of internal goals with performance against the broader market and demonstrates value creation for our stockholders ​ ▪ Payout ranges from 0% to 200% of the target award, with a threshold payout of 40% of target ​ ▪ Set 2026 — 2028 organic ROIC target of 15.9%, with a threshold of 11.8% and a maximum of 17.8% ​ ▪ Organic ROIC is defined as the quotient of average annual net operating profit after taxes, over the average annual invested capital determined as total assets less cash and cash equivalents minus total liabilities less short- and long-term debt, as may be adjusted for acquisitions, accounting or tax changes, gains or losses from discontinued operations, and certain other unusual or infrequently occurring charges during the performance period. Invested capital is not adjusted for acquisitions completed prior to the start of the performance period ​ ▪ Includes relative TSR modifier, which may increase or reduce the payout based on the Company’s three-year TSR compared to the S&P 500 three-year TSR, with performance in the 80th percentile or higher increasing the payout percentage by 10% and performance in the 20th percentile or lower decreasing the payout percentage by 10% (subject to cap on total payout of 200% of target) ​ ▪ No dividend equivalents are paid or accrued on PBRSUs ​	​
​	STOCK OPTIONS	​	​	​	▪ Vests in equal annual installments over three years ​ ▪ Exercise price equal to the average of the high and low market price on the date of grant, which we believe lessens the impact of potential same-day stock volatility ​ ▪ 10-year term from the date of grant ​	​

PAYOUT OF 2023 – 2025 PBRSUs

Each of our NEOs, except Ms. King, held outstanding 2023 – 2025 PBRSUs granted by the Compensation & HCM Committee in December 2022, which vested on December 31, 2025. The following chart sets forth the threshold and target average annual adjusted ROIC and the Company’s actual average annual adjusted ROIC performance under the 2023 – 2025 PBRSUs, which resulted in a payout at 100% of target (the maximum potential payout for these awards).

Adjusted ROIC under the 2023 – 2025 PBRSUs is defined as the quotient of after-tax operating income divided by the sum of short-term and long-term debt and stockholders’ equity, less cash and cash equivalents. Adjusted ROIC is measured excluding the purchase accounting impact and special gains and charges relating to the Nalco and Purolite transactions considering the significant impact of these transactions on the calculation in accordance with the terms of the award.

TABLE OF CONTENTS​

Executive Compensation

​ Equity Award Grant Practices ​

Generally, long-term equity incentives for executives are granted on the same date as our Compensation & HCM Committee approval date, and in no event is the grant date prior to the approval date. Annual grants are typically made at the Compensation & HCM Committee’s regularly scheduled meeting in December. The Compensation and HCM Committee did not take material nonpublic information into account when determining the timing and terms of equity awards in 2025. We do not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. In addition, in 2025, we did not grant long-term equity incentives (including stock options) during any period beginning four business days before and ending one business day after the filing of any periodic report on Form 10-Q or Form 10-K, or the filing or furnishing of any current report on Form 8-K that discloses material nonpublic information. We may change our equity grant practices in the future.

​ Executive Benefits and Perquisites ​

Our NEOs participate in the same health care, disability, life insurance, pension, and 401(k) benefit plans made available generally to the Company’s U.S. employees, with executive supplements as described in this Proxy Statement. In addition, our NEOs are eligible to participate in:

▪

a deferred compensation program,

​

▪

a restoration plan for the tax-qualified 401(k) plan,

​

▪

a restoration pension plan, and

​

▪

with respect to certain of our NEOs, an executive disability and life benefit and a supplemental retirement benefit.

​

The non-qualified retirement plans supplement the benefits provided under our tax-qualified plans, taking into account compensation and benefits above the IRS limits for qualified plans. The NEOs also receive limited perquisites that are described in more detail in the footnotes to the “Summary Compensation Table for 2025”. Perquisites accounted for 0.7% of total compensation for the CEO and 1.2% of total compensation on average for the other NEOs in 2025. Executive benefits and perquisites are consistent with our competitive market.

The Company maintains a private aircraft use policy authorizing the use of private aircraft for business and personal purposes by the Company’s Chairman and Chief Executive Officer and, under certain circumstances, business use by its directors and certain other executives. Under the policy, personal use of private aircraft by the Chairman of the Board and Chief Executive Officer is limited to $150,000 of unreimbursed usage per year, with personal use historically falling below the limit. Additional information with respect to this perquisite is provided in more detail in the footnotes to the “Summary Compensation Table for 2025”.

Mr. Brown received an annual commuter allowance of $50,192 that is designed to offset commuting expenses incurred for travel to headquarters. Mr. Brown did not receive any tax gross-up on this allowance.

OTHER COMPENSATION POLICIES AND CONSIDERATIONS

​ Executive Change-In-Control Policy ​

The terms of our Change-In-Control Severance Compensation Policy, including the events constituting a change in control under our policy, are described in the “Potential Payments upon Termination or Change in Control” section of this Proxy Statement. Our policy applies to all elected officers, including the NEOs, except those who are covered by separate change-in-control or similar agreements with the Company or a subsidiary, a circumstance which arises only in the case of an executive having such an agreement with a company we acquire, which agreements are not renewed after they terminate or expire. The Change-In-Control Severance Compensation Policy only provides “double-trigger” severance benefits following a change-in-control, which promotes the interests of stockholders by mitigating executives’ concerns about the impact a change in control may have on them, thereby allowing the executives to focus on the best interests of stockholders under such circumstances.

​ Global Insider Trading Policy ​

Our Global Insider Trading Policy governs the trading of our securities by our directors, officers, employees, and consultants. It also requires the Company to comply with all applicable securities and state laws when engaging in transactions in its own

​ 56    CONSISTENT HIGH PERFORMANCE ​ ​ ​ ​

TABLE OF CONTENTS

Executive Compensation

securities. We believe that the policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards applicable to the Company. A copy of the Global Insider Trading Policy was filed as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended December 31, 2025.

​ Hedging and Pledging Policy ​

The Company’s Global Insider Trading Policy provides that certain short-term or speculative transactions by insiders in Company securities are prohibited at any time. These include:

(i)

short-term “in and out” trading;

​

(ii)

selling Company stock short;

​

(iii)

purchases of Company stock on margin;

​

(iv)

pledging of Ecolab stock; and

​

(v)

dealing in derivative securities (e.g., options, puts, calls) other than through the Company’s stock incentive plans.

​

Our directors, executive officers (including our NEOs), senior management team, and certain other employees designated from time to time by the General Counsel constitute the Company’s “insiders” under the policy.

​ Stock Retention and Ownership Guidelines ​

​	We maintain stock retention and ownership guidelines to encourage our NEOs and other executives to accumulate a meaningful ownership stake in the Company so they are incentivized to maximize long-term stockholder returns without taking on undue risk. Until the guideline is met, our CEO, CFO and President and COO are expected to retain 100% of net shares realized from equity awards, with other officers expected to retain 50%. Shares subject to unexercised stock options and unvested restricted stock units (RSUs) and PBRSUs are not considered owned for purposes of complying with the guidelines.	​	​
			​		​

The table below illustrates the standing of each of our NEOs in relation to their respective stock ownership guideline as of December 31, 2025, based on the closing market price of our Common Stock on December 31, 2025 of $262.52 per share.

​ Clawback and Compensation Recovery Policies ​

The Company’s Board of Directors has adopted a Policy on Reimbursement of Incentive Payments. Under this policy, if an executive has engaged in misconduct (including a material violation of the Company’s Code of Conduct), as determined by the Compensation & HCM Committee, then the Company will, in appropriate circumstances, recoup annual or long-term cash or equity-based incentives or discretionary bonuses (whether based on financial measures, stock price, TSR or non-financial measures), as well as time-based stock options or other equity-based awards (collectively, “incentive compensation”). In addition, in the event of an accounting restatement of the Company’s financial statements due to material non-compliance with any financial reporting requirement under the federal securities laws or if incentive compensation is paid based on a materially inaccurate calculation, the Compensation & HCM Committee may recoup any excess incentive compensation during the prior three fiscal years.

​ ​ ​ ​ ECOLAB PROXY STATEMENT 2026    57 ​

TABLE OF CONTENTS​

Executive Compensation

The Company’s Board of Directors has also adopted a Rule 10D-1 Clawback Policy, which is intended to comply with the requirements of NYSE Listing Standard 303A.14 implementing Rule 10D-1 under the Exchange Act. In the event the Company is required to prepare an accounting restatement of the Company’s financial statements due to material non-compliance with any financial reporting requirement under the federal securities laws, the Company will recover the excess incentive-based compensation received by any covered executive, including the NEOs, during the prior three fiscal years that exceeds the amount that the executive otherwise would have received had the incentive-based compensation been determined based on the restated financial statements.

COMPENSATION RISK ANALYSIS

The Compensation & HCM Committee has established an annual process for assessing risk in our compensation programs. The Committee has directed management to apply that process to all compensation plans and practices that have the potential to create risks that are reasonably likely to have a material adverse effect on the Company and to report the results to the Compensation & HCM Committee. Management undertakes this assessment with the assistance of the Compensation & HCM Committee’s independent advisor, FW Cook, including the review and alignment on the assessment methodology and results. The Committee maintains final authority for overseeing risk in our compensation programs.

Based on our 2025 risk assessment, we do not believe that our compensation programs create risks that are reasonably likely to have a material adverse effect on the Company. In making this determination, we took into account the compensation mix for our employees as well as various risk control and mitigation features of our programs, including:

​	COMPENSATION PROGRAM RISK CONTROL AND MITIGATION FEATURES	​	​	​		​	​	Varied and balanced performance targets	​
				​		​	​	Procedures for incentive pay calculations review	​
				​		​	​	Appropriate incentive payout caps	​
				​		​	​	Discretionary authority of the Compensation & HCM Committee to reduce award payouts	​
				​		​	​	Internal controls around customer and distributor pricing and contract terms	​
				​		​	​	Stock ownership guidelines	​
				​		​	​	Prohibition on hedging or pledging Company stock	​
				​		​	​	Compensation recovery (“clawback”) policies and the Company’s rights to cancel incentive awards for employee misconduct	​

(1)

Includes amounts deferred under Section 401(k) of the Internal Revenue Code pursuant to the Ecolab Savings Plan and ESOP, amounts deferred under a non-qualified defined contribution deferred compensation plan maintained by the Company for a select group of executives, and any salary reductions per Section 125 or Section 132(f)(4) of the Internal Revenue Code.

​

(2)

Represents the aggregate grant date fair value of PBRSU awards at target and RSU awards made during the year in accordance with FASB ASC Topic 718, in each case, adjusted for the absence of future dividends and with no discount for estimated forfeitures. For the 2026-2028 PBRSU awards, which are subject to a relative TSR modifier, the grant date fair value is determined using a Monte Carlo simulation model. For Ms. King’s RSU award and 2025-2027 PBRSU award, which are not subject to the relative TSR modifier, the grant date fair values are determined based on the average of the high and low share price of the Company’s common stock on the date of grant. See Note 11 to the Company’s Consolidated Financial Statements for the year ended December 31, 2025, located at Item 8 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, for further discussion of the assumptions used in determining these values. For additional information about these awards see the heading “Long-Term Equity Incentives” beginning at page 54 and the footnotes to the table “Grants of Plan-Based Awards for 2025” beginning at page 61. Based on the fair market value on the date of grant ($264.95 per share), the maximum values for the 2026-2028 PBRSUs granted to Messrs. Beck, Kirkland, Brown and Cook and Ms. King are $14,456,202, $3,493,631, $3,734,735, $1,927,246 and $1,445,567, respectively. Based on the fair market value on the date of grant ($257.88 per share), the maximum value for the 2025-2027 PBRSUs granted to Ms. King are $1,286,305.

​

(3)

Represents the aggregate grant date fair value of stock option grants during the year in accordance with FASB ASC Topic 718 but with no discount for estimated forfeitures. The value of grants has been determined by application of the lattice (binomial)-pricing model. Key assumptions include risk-free rate of return, expected life of the option, expected stock price volatility, and expected dividend yield. See Note 11 to the Company’s Consolidated Financial Statements for the year ended December 31, 2025, located at Item 8 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, for further discussion of the assumptions used in determining these values. The specific assumptions used in the valuation of the options granted in 2025 are summarized in the table below:

TABLE OF CONTENTS

Executive Compensation

(4)

Represents the annual cash incentive awards earned and paid in respect of 2025 under the Company’s MIP. The MIP is discussed in more detail at page 50 and as part of the table entitled “Grants of Plan-Based Awards for 2025” at page 61.

​

(5)

Represents the aggregate change in the actuarial present value of the NEO’s accumulated benefit under the Company’s defined benefit plans as of December 31, 2025 over such amount as of December 31, 2024, except as otherwise noted. The Company’s defined benefit plans include the Pension Plan, the Mirror Pension Plan, the Supplemental Executive Retirement Plan (“SERP”), and the AMP Signature Super — One Ecolab Superannuation Plan (“Australia Plan”) which are discussed beginning at page 66 as part of the table entitled “Pension Benefits for 2025.” Mr. Brown is an inactive participant in the Australia Plan, which is a broad-based pension plan covering certain Australian employees, and no other named executive officer participates in the Australia Plan. The change in the actuarial present value during 2025 of Mr. Brown’s Australia Plan benefit is primarily attributable to changes in actuarial assumptions and increases related to the passage of time and does not reflect any additional accruals for service or compensation earned or paid in 2025. Mr. Brown’s change in pension benefit attributable to this plan is accrued in Australian dollars and is reported based on a conversion rate of 1.5267AUD = 1$U.S. on November 30, 2025, a conversion rate of 1.5356AUD = 1$U.S. on November 30, 2024, and a conversion rate of 1.5140AUD = 1$U.S. on November 30, 2023, using pension measurement dates of November 30, 2025, November 30, 2024, and November 30, 2023, consistent with the Company’s assumptions under FASB ASC Topic 715 for financial reporting regarding international retirement plans. There are no “above market” earnings under the Ecolab Mirror Savings Plan, a non-qualified defined contribution plan, because all earnings under this plan are calculated at the same rate as earnings on one or more externally managed investments available to participants in Ecolab’s broad-based tax-qualified deferred compensation plans. The Ecolab Mirror Savings Plan is discussed at page 69.

​

(1)

Threshold amount is based on achievement of the minimum adjusted EPS performance measure at 40% of target (which also comprises a portion of the enterprise goal), minimum achievement of the applicable business unit goals at 40%, no achievement of the commercial average payout component, minimum achievement of individual goals, and assuming the Growth & Impact modifier is not achieved and the negative 10% modifier applies. Ms. King’s MIP performance measures for the period prior to June 1, 2025 do not include the Growth & Impact modifier.

​

(2)

Except for Ms. King’s 2025-2027 PBRSU award, threshold amount is calculated assuming the relative TSR modifier is not achieved and the negative 10% modifier applies. The relative TSR modifier does not apply to Ms. King’s 2025-2027 PBRSU award.

​

(3)

Amounts reflect the threshold (adjusted as noted in footnote 2 above), target, and maximum number of shares of Company Common Stock that may be earned pursuant to PBRSU awards granted in 2025. No PBRSUs may be earned if organic ROIC is below the threshold goal, and no more than 200% of the PBRSUs may be earned if organic ROIC is above the maximum goal. Except for Ms. King’s 2025-2027 PBRSU award, a relative TSR modifier may increase or reduce the payout percentage based on our 3-year TSR compared to the S&P 500, subject to the cap on total payout of 200% of target. Dividend equivalents are not paid or accrued during the performance period. See the discussion under the heading “Long-Term Equity Incentives” in the Compensation Discussion and Analysis for more information on these awards, including with respect to the performance goals and relative TSR modifier.

​

(4)

Represents the grant of a restricted stock unit award to Ms. King, which will vest as to one-third of the units on each of the first three anniversaries of the date of grant. Dividend equivalents are not paid or accrued on unvested units.

​

(5)

Options granted in 2025 have a ten-year contractual exercise term and vest (or will be exercisable) over three years, on a cumulative basis, as to one third of the option shares on the first and second anniversaries of the date of grant and as to the remaining option shares on the third anniversary.

​

(6)

Each of the stock options granted to our NEOs during the year ended December 31, 2025 and reported in the table above were granted on the date of approval and have an exercise price which is the average of the high and low market price on the date of grant. We believe that the use of the average of the high and low market price on the date of the grant removes the effect of potential same-day stock volatility.

Executive Compensation

(7)

Represents the grant date fair value of each equity award, computed in accordance with FASB ASC Topic 718, disregarding the effect of estimated forfeitures. The manner in which grant date fair value was determined for stock awards and option awards granted in 2025 is discussed in footnote (2) and (3), respectively, to the “Summary Compensation Table for 2025” at page 59.

​

(8)

The Company maintains an annual cash incentive program for executives referred to as the MIP, which is discussed in the Compensation Discussion and Analysis under the heading “Annual Cash Incentives.” In the case of the NEO participants, the potential payouts that could be earned under the MIP for 2025 and that would be used to guide the Committee’s discretion under the MIP are noted in the MIP row of the above table. Amounts shown are based on the base salary earned during 2025. Actual payouts to each of the NEOs with respect to 2025 are included under the Non-Equity Incentive Plan Compensation column in the “Summary Compensation Table for 2025” at page 59. Each award is subject to and interpreted in accordance with the terms and conditions of the MIP, and no amount will be paid under the MIP unless and until the Committee has determined the extent to which the applicable performance goal has been met, the corresponding amount of the award earned by the participant, and the degree to which the Committee chooses to exercise its permitted discretion under the MIP.

The table shows the actuarial present value of the accumulated benefit for each executive officer under the plans identified above as of December 31, 2025 (or November 30, 2025, for the Australia Plan).

​

▪

The actuarial present value is calculated using the same assumptions as are used by the Company for financial reporting purposes under generally accepted accounting principles, except that retirement age is assumed to be age 62. The present value is determined by using a discount rate of 5.30% for the Pension Plan and 4.80% for the Mirror Pension Plan and SERP for 2025 and assuming that benefits are vested at December 31, 2025. The present value of Mr. Brown’s current accrued benefit in the Australia Plan was determined based on a 4.53% discount rate and based on a conversion rate of 1.5267AUD = 1$U.S.

​

▪

The current accrued benefit for U.S. benefits is allocated between the tax-qualified Pension Plan and the related supplemental non-qualified plans based on the Internal Revenue Code limitations applicable to tax-qualified plans as of December 31, 2025.

​

▪

The present value of the Pension Plan, generally payable as a single life annuity, assumed mortality rates from the “Pre-2012 Mortality Table” with the MP-2021 projection scale and Endemic COVID scale. Mirror Pension and SERP annuities were valued assuming annual installment payments, or lump sums where available, using an interest rate of 5.08% and the mortality rates defined in the Mirror Pension and SERP plans as prescribed in Revenue Ruling 2001-62. Cash balance benefits were valued assuming future interest credits of 4.09% for periods after December 31, 2025. The cash balance annuity conversion for the SERP offset used the interest rate and mortality assumptions prescribed by the IRS under Internal Revenue Code Section 417(e) for pension lump-sum calculations at December 31, 2020, when the SERP benefit was frozen.

Pension Plan(1)

​

​

​

Tax-qualified defined benefit plan that covers most U.S. employees of the Company and its U.S. affiliates.

​

​

​

Cash balance account credit at the end of each year equal to 3% of the participant’s compensation for that year plus an interest credit applied to the participant’s account balance on the first day of that year. ▪ Compensation includes base salary and annual cash incentive compensation for a plan year, and excludes long-term and non-cash incentive bonuses, up to IRS qualified plan compensation limit. ​

​

​

​

Vested after 3 years of continuous service.

​

​

​

Actuarial equivalent value of account balance using mortality and interest factors prescribed by the IRS for cash balance plans. ▪ Normal form of benefit is a single life only annuity for unmarried participants; joint and 50% survivor annuity for married participants. ​ ▪ Optional forms of benefit include lump-sum and annuity options; death benefit to beneficiary if die before starting pension. ​

​

​

​

N/A — benefit payable at termination of employment; no subsidies for early retirement.

​

​

Mirror Pension Plan(1)

​

​

​

Non-qualified plan intended to restore benefits under the tax-qualified Pension Plan for certain executives whose benefits under the Pension Plan are reduced by Internal Revenue Code limits.

​

​

​

Same as Pension Plan, but only with respect to compensation and benefits that would otherwise exceed IRS qualified plan limits.

​

​

​

Vested after 3 years of continuous service and in the event of a change-in-control.

​

​

​

Actuarial equivalent value of account balance using mortality and interest factors prescribed by the IRS for cash balance plans. ▪ Normal form of benefit is 10 annual installments commencing after separation from service. ​ ▪ Optional forms of benefits available to participants include 5-year annual installments, lump sum and annuity options. ​ ▪ Payment is in a lump sum if the present value does not exceed $25,000 at time of distribution. ​ ▪ Payments of benefits subject to Internal Revenue Code Section 409A to “specified employees” are delayed until 6 months after separation from service, and further delayed in accordance with IRS rules if an executive changes the time or form of payment. ​

After December 31, 2020, Mr. Cook accrued benefits under the cash balance formula described above. From his entry into the plan through December 31, 2020, Mr. Cook earned monthly pension benefits under the “traditional” formula: 1/12 of the sum of: (a) years of credited service times 1% of “final average compensation” plus (b) years of credited service (not exceeding 35) times 0.45% of “final average compensation” minus “covered compensation.” “Final average compensation” is the average of the participant’s annual compensation for the five consecutive calendar years, that produce the highest average, counting the participant’s base salary and annual cash incentive compensation for a plan year, excluding any long-term and non-cash incentive bonuses and amounts above the IRS compensation limits for qualified plans, and taking into account only compensation earned through December 31, 2020. “Covered compensation” is the average Social Security taxable wage base over a 35-year period ending at a participant’s Social Security retirement age. Under the “traditional” formula, if Mr. Cook retires on or after age 55, his “traditional” formula benefits expressed in the form of an annuity are reduced by 1/280 for each month by which payment begins before age 62. Unreduced benefits may begin after attaining age 62. Mr. Cook is fully vested in these pension benefits. Certain other rules apply to benefits accrued prior to the effective date of IRC Section 409A.

TABLE OF CONTENTS​

Executive Compensation

Potential Payments Upon Termination or Change in Control

The Company maintains certain plans, policies, and practices covering NEOs that will require it to provide incremental compensation upon certain types of terminations, including termination due to a change in control of the Company.

​ Overview ​

The following discussion describes additional amounts that the Company would pay or provide to an NEO or his or her beneficiaries as a result of termination of employment in each of the following situations: voluntary resignation, discharge for cause, discharge without cause, resignation due to constructive discharge, death or disability, and change in control of the Company. For purposes of this discussion, estimated benefits are calculated as if the termination and/or change in control occurred on December 31, 2025; PBRSU and RSU awards are valued based on the value of a share of the Company’s stock of $262.52, which is the closing price on December 31, 2025, the last business day of the Company’s fiscal year; and option awards are valued based on the difference between $262.52 and the per share exercise price of the respective awards.

As permitted by SEC rules, the following discussion and amounts do not include the payments and benefits that are not enhanced by the termination of employment or change in control. These payments and benefits are referred to in this discussion as “vested benefits.”

​ Voluntary Resignation or Retirement ​

The Company is not obligated to pay any amounts in addition to the NEO’s vested benefits in the event of a voluntary termination of employment, unless the executive’s age and years of service qualify for special provisions applicable for retirement under the plans described below. Three of our NEOs, Mr. Beck, Mr. Brown and Mr. Cook, would have been eligible for some or all of such special retirement provisions as of December 31, 2025, as follows:

If termination is after age 55 and completion of at least five years of service, the executive would receive their earned annual cash incentive under the Company’s annual cash incentive program as reported in the Non-Equity Incentive Plan Compensation column of the “Summary Compensation Table for 2025” at page 59.

​

(2)

Certain elected corporate officers, including Mr. Beck, who terminate employment at or after: (i) attaining age 55 and completing at least ten years of service or (ii) attaining age 65, are covered by an executive life insurance policy. Under the program, the beneficiary of the retired executive is entitled to a death benefit equal to two times the executive’s average compensation for the five consecutive years of employment preceding retirement which yields the highest average compensation, subject to a maximum of $750,000.

​

(3)

If termination is after: (i) age 55 and (ii) completion of at least five years of service, the NEO would be entitled to accelerated vesting for options held at least six months and an extended, post-retirement exercise period of five years (or the remaining term of the options, if shorter). Otherwise, all options may be exercised at any time during the three months after termination of employment, but not beyond the original ten-year term of the option.

​

(4)

If termination is after: (i) age 55 and (ii) completion of at least five years of service, service-vesting conditions with respect to PBRSU awards held at least six months will be deemed satisfied, but vesting remains subject to the attainment of performance goals. The listed value of the accelerated vesting of the PBRSUs for each of the NEOs assumes attainment of target performance, payment after the end of the performance period, and a stock price of $262.52.

Certain executives who become “disabled” will, following a 180-day elimination period, receive payments from the Company equal to 60% of his or her base salary and annual cash incentive, reduced by the benefit paid under the Company’s insured long-term disability plan available to all full-time employees (which is limited to $15,000 per month). Total disability benefits are limited to $35,000 per month.

​

(2)

Mr. Beck is covered by an executive life insurance policy which provides his beneficiary with an insured basic executive death benefit equal to three times base salary and target annual cash incentive for the year preceding the death, subject to a maximum benefit of $9,000,000; for an accidental death, an additional amount equal to the lesser of the death benefit or $6,000,000; for a death while on Company business, an additional amount equal to the lesser of three times annual compensation for the year preceding the death or $6,000,000.

​

(3)

In the event of the executive’s death or disability, the NEO would receive their earned annual cash incentive under the Company’s annual cash incentive program as reported in the Non-Equity Incentive Plan Compensation column of the “Summary Compensation Table for 2025” at page 59.

​

If employment terminates as a result of death or disability, the vesting of options is accelerated and the post-death/disability exercise period is extended to five years (or the remaining term of the options, if shorter). The closing stock price on December 31, 2025, the last business day of the Company’s fiscal year, of $262.52, is below the exercise price of certain stock options that would be accelerated and which are reported as having no intrinsic value, as follows: Mr. Beck, 64,954 options; Mr. Kirkland, 15,697 options; Mr. Brown, 16,780 options; Mr. Cook, 8,661 options; and Ms. King, 12,433 options.

​

(5)

If employment terminates as a result of death or disability, service-based vesting conditions on PBRSUs will be deemed satisfied, but vesting remains subject to attainment of performance goals. The listed value of the accelerated vesting of the PBRSUs for each of the NEOs assumes attainment of target performance, payment after the end of the performance period, and a stock price of $262.52.

​

(6)

If employment terminates as a result of death or disability, the vesting of RSU awards is accelerated.

​

(7)

Amounts are with respect to PBRSUs for Messrs. Beck, Kirkland and Brown, and PBRSUs and RSUs for Mr. Cook (11,637 PBRSUs for $3,054,945 and 8,396 RSUs for $2,204,118) and Ms. King (5,222 PBRSUs for $1,370,879 and 4,988 RSUs for $1,309,450).

​

​ Discharge Not for Cause; Resignation Due to Constructive Discharge ​

The Company negotiates separation arrangements on a case-by-case basis if an executive’s employment is terminated involuntarily without cause or if the executive resigns as a result of a constructive discharge. Any such negotiated settlement would be conditioned on the executive signing a general release and waiver of claims against the Company and would typically require compliance with confidentiality and non-compete restrictions. Cash separation payments will generally be made in equal installments over regular payroll periods.

TABLE OF CONTENTS

Executive Compensation

The PBRSU awards provide that vesting of the service-based vesting conditions will be accelerated on a pro-rated basis in the event an executive’s employment is terminated without cause, with payment of the pro-rated award subject to satisfaction of applicable performance criteria. In addition, the Compensation & HCM Committee may, at its discretion, accelerate the vesting of long-term incentive awards.

The listed value of the accelerated vesting of the PBRSUs for each of the NEOs assumes attainment of target performance, payment after the end of the performance period, and a stock price of $262.52.

​

Furthermore, if an executive’s position, age, and years of service qualify at time of termination, the executive would receive benefits under the same special provisions applicable for retirement as are described in the section entitled “Voluntary Resignation or Retirement” above. As noted in that section, three of our NEOs, Mr. Beck, Mr. Brown and Mr. Cook, would have been entitled to such special retirement provisions as of December 31, 2025.

​ Change in Control (Double Trigger) ​

The Company maintains a Change-in-Control Severance Compensation Policy (the “Policy”) which applies to elected officers (other than assistant officers) of the Company, including each NEO. The Policy provides for benefits if, within two years following a change in control, the officer’s employment with the Company is terminated without Just Cause (as defined in the Policy) or the officer voluntarily terminates employment for Good Reason (as defined in the Policy), conditioned on the executive’s execution of a general release and waiver of claims. The Policy does not provide a gross-up for the 280G excise tax. However, the Policy does provide for a reduction of payments if the Policy results in higher after-tax income to the participant due to 280G excise tax.

The Company’s stock incentive plans also provide for certain benefits at change in control as defined in those plans. Unless an outstanding option, PBRSU award or RSU award is continued, assumed, or replaced by the Company or the surviving or successor entity in connection with the change in control, or if such option or award is continued, assumed or replaced but an executive’s employment or other service is terminated without Cause or is terminated by the executive for Good Reason within two years after the change in control, then:

(i)

each of the executive’s outstanding options will become exercisable in full and remain exercisable for the remaining term of the option,

​

(ii)

each of the holder’s unvested RSU awards and PBRSU awards will fully vest, and

​

(iii)

any performance goals applicable to the holder’s PBRSU awards will be deemed to have been satisfied to the target level of performance.

​

However, in the event the awards are not continued, assumed or replaced by the Company or the surviving or successor entity, the Compensation & HCM Committee may elect to terminate such options or awards in exchange for a payment with respect to each option or award in an amount equal to the excess, if any, between the fair market value of the shares subject to the option or award immediately prior to the effective date of such change in control (which may be the fair market value of the consideration to be received in the change-in-control transaction for the same number of shares) over the aggregate exercise price (if any) for the shares subject to such option or award (or, if there is not excess, such option or award may be terminated without payment).

Our non-GAAP adjusted financial measure for diluted earnings per share excludes the impact of special (gains) and charges and the impact of discrete tax items. We include items within special (gains) and charges and discrete tax items that we believe can significantly affect the period-over-period assessment of operating results and not necessarily reflect costs associated with historical trends and future results. After tax special (gains) and charges are derived by applying the applicable local jurisdictional tax rate to the corresponding pre-tax special (gains) and charges. See “Performance Measures and Achievement  —  Adjusted EPS” in our CD&A for a reconciliation of this Non-GAAP measure to its most directly comparable financial measure calculated and presented in accordance with GAAP.

FINANCIAL PERFORMANCE MEASURES

As described in greater detail in the “Compensation Discussion and Analysis,” the Company’s compensation programs are designed to enable us to attract and retain the leadership talent that is necessary to successfully manage our strong earnings growth and return on invested capital objectives, while balancing necessary investment in the businesses in order to achieve attractive, long-term shareholder returns.

PAY RATIO DISCLOSURE

For the year ended December 31, 2025, the annual total compensation for our CEO was $17,404,935, as reported in the final column of the “Summary Compensation Table for 2025” at page 59, and the annual total compensation for our identified global median employee was $53,462, calculated in accordance with the rules applicable to the “Summary Compensation Table for 2025.” For the year ended December 31, 2025, the annual total compensation for our CEO was 326 times the annual total compensation for our global median employee.

We concluded that there were no significant changes to our employee population or employee compensation arrangements since 2023 that we believe would significantly impact our pay ratio disclosure. However, the median employee we had selected for 2023 had anomalous pay characteristics for 2024, and, thus, we substituted a substantially similar alternate median employee from the previously identified median group for 2024, whom we continued to use for 2025.

For purposes of identifying our global median employee, we used our global employee population as of November 1, 2023, which consisted of 53,048 total global employees, of whom 19,418 were employed in the United States and 33,630 were employed in foreign jurisdictions. As permitted by SEC rules, we excluded leased employees and independent contractors, as well as 2,599 employees in the following foreign jurisdictions:

​	Venezuela	​	​	​	​	​	86	​	​
​	Malta	​	​	​	​	​	103	​	​
​	Vietnam	​	​	​	​	​	122	​	​
​	Egypt	​	​	​	​	​	202	​	​
​	Philippines	​	​	​	​	​	858	​	​
​	Indonesia	​	​	​	​	​	966	​	​
​	​	​	​	​	​	​	​	​	​

​

After giving effect to these exclusions, the number of global employees from which our global median employee was identified was 50,449. To identify the median employee, we first calculated the sum of base salary and target bonus for the global population. We annualized this amount for global employees who commenced employment during that period. For global employees paid in currencies other than U.S. dollars, we converted to U.S. dollars using treasury rates as of September 30, 2023. Upon calculating the median amount of compensation utilizing this methodology, we applied statistical sampling with the assistance of an outside expert to identify the population of global employees with compensation within a 5 percent range around the median. From this population of employees, we identified a median employee. The median employee we had selected for 2023 had anomalous pay characteristics for 2024, and, thus, we substituted a substantially similar median employee from this group for 2024, whom we continue to use for 2025.

We believe the pay ratio presented above is a reasonable estimate calculated in a manner consistent with applicable SEC rules. Because the SEC rules for identifying the global median employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above.

​ PROPOSAL 3 — RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ​ ​ ​ ​ ​ The Board of Directors recommends that the stockholders vote FOR the ratification of the appointment of PwC as our independent registered public accounting firm for the year ending December 31, 2026. ​

The Audit Committee is directly responsible for the appointment, compensation, retention, and oversight of our independent auditors. The Audit Committee assesses the independent auditor annually, and considers many factors, including:

▪

the firm’s independence and process for monitoring and maintaining its independence,

​

▪

the capabilities of the firm’s personnel and key members of the engagement team,

​

▪

how well the firm meets agreed objectives for the audit,

​

▪

the firm’s responsiveness,

​

▪

the firm’s objectivity,

​

▪

their knowledge of our business,

​

▪

their status as a registered public accounting firm with the Public Company Accounting Oversight Board (United States) (“PCAOB”) as required by the Sarbanes-Oxley Act of 2002 and the Rules of the PCAOB,

​

▪

the reasonableness of the fees for the engagement, and

​

▪

the quality and frequency of communication with the Company and the Audit Committee.

​

The Audit Committee requires the lead engagement partner to rotate periodically, and no less frequently than every five years, to support their independence.

After assessing the qualifications, performance, and independence of PricewaterhouseCoopers LLP (“PwC”), which has served as this Company’s independent auditor since 1970, the Audit Committee appointed PwC as our independent registered public accounting firm to audit our consolidated financial statements for the year ending December 31, 2026, and to perform other appropriate services. The Audit Committee considered a number of factors in determining whether to re-engage PwC as the Company’s independent registered public accounting firm for the year ending December 31, 2026, including:

▪

the firm’s professional qualifications and resources,

​

▪

the firm’s past performance,

​

▪

the firm’s capabilities in handling the breadth and complexity of our business,

​

▪

the length of time the firm has served in this role, and

​

▪

the potential impact of changing independent auditors which may include loss of efficiencies.

​

Representatives of PwC are expected to be present at our Annual Meeting of Stockholders. They will have an opportunity to make a statement if they desire to do so and are expected to be available to respond to appropriate questions.

PwC has provided professional services to the Company in 2025, the aggregate fees and expenses of which are reported at page 82.

​ ​ ​ The Board of Directors recommends that the stockholders vote FOR the ratification of the appointment of PwC as our independent registered public accounting firm for the year ending December 31, 2026. Although stockholder ratification of the appointment of our independent registered public accounting firm is not required, the Board believes it is a matter of good governance to submit the appointment of PwC for stockholder consideration and ratification. If the appointment of PwC is not ratified, the Audit Committee will reconsider the matter but will not be required to change its decision to appoint PwC as independent registered public accounting firm. Unless a contrary choice is specified, proxies solicited by our Board of Directors will be voted FOR the ratification of the appointment of PwC. ​

AUDIT COMMITTEE REPORT

Our Audit Committee is comprised of the members listed below, each of whom the Board has determined to be independent under the NYSE listing standards, SEC rules, and our Corporate Governance Principles, and each of whom is financially literate as defined under NYSE listing standards. The Board has determined that Ms. Reich, Mr. Nowell and Ms. Whalen each qualify as audit committee financial experts as defined by SEC rules. The Audit Committee operates under a written Charter and the functions of the Committee are described under the heading “Board Committees — Audit Committee” at page 27 hereof. The Audit Committee’s Charter recognizes that it is the responsibility of management to prepare the Company’s financial statements in accordance with Accounting Principles Generally Accepted in the United States of America and to maintain an effective system of financial control; and that it is the responsibility of the independent auditors to plan and conduct the annual audit and express their opinion on the consolidated financial statements in accordance with professional standards. As recognized in the Charter, the Committee’s responsibilities include overseeing the work of the participants in the financial reporting and control process. The Audit Committee meets periodically with management, including with the Company employee primarily responsible for preparing financial statements, the employee primarily responsible for internal audit activities, the Company’s Chief Compliance Officer, and also meets periodically with the Company’s registered public accounting firm, PwC.

The Audit Committee has:

(i)

reviewed and discussed the audited consolidated financial statements of the Company as of December 31, 2025, and for the year then ended (the “Financial Statements”) with management which has represented that the Financial Statements were prepared in accordance with Accounting Principles Generally Accepted in the United States of America,

​

(ii)

discussed the Financial Statements with PwC (our independent registered public accounting firm), including the matters required to be discussed by the applicable requirements of the PCAOB and SEC, and

​

(iii)

received the written disclosures and the letter from PwC required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence and has discussed with PwC their independence.

​

The Committee has also considered and determined that PwC’s provision of non-audit services as described below under the heading “Audit Fees” do not compromise PwC’s independence.

Based on the foregoing review and discussions, the Audit Committee recommended to the Board of Directors, and the Board has approved, that the Financial Statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, for filing with the SEC.

​ PROPOSAL 4 — STOCKHOLDER PROPOSAL REGARDING AN INDEPENDENT BOARD CHAIR POLICY​ ​ ​ ​ ​ ​ The Board of Directors unanimously recommends that the stockholders vote AGAINST this stockholder proposal. ​

Mr. John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, CA 90278, who owns no fewer than 100 shares of our Common Stock, has requested that the following proposal be included in this proxy statement and voted on at the Annual Meeting. The Company disclaims any responsibility for the accuracy or content of this proposal, which is presented in the form received from the proponent in accordance with SEC rules.

After careful consideration, the Board of Directors unanimously recommends that you vote AGAINST the stockholder proposal set forth below.

STOCKHOLDER PROPOSAL

Proposal 4 — Independent Board Chairman

Shareholders request that the Board of Directors adopt an enduring policy, and amend the governing documents as necessary including the Corporate Governance Guidelines in order that 2 separate people hold the office of the Chairman and the office of the CEO as soon as possible.

The Chairman of the Board shall be an Independent Director. An independent Lead Director shall not be a substitute for an independent Board Chairman.

The Board shall have the discretion to select an interim Chairman of the Board, who is not an Independent Director, to serve while the Board is required to seek an Independent Chairman of the Board on an accelerated basis. This policy could be phased in when there is a contract renewal for our current CEO or for the next CEO transition although it is better to adopt it now to obtain the maximum benefit.

An independent Board Chairman at all times improves corporate governance by bringing impartiality, objective oversight, and external expertise to board decisions, mitigating conflicts of interest, enhancing transparency , and boosting shareholder confidence.

This detached perspective allows the chairman to focus on shareholder interests, strengthen management accountability, and provide critical checks and balances, ultimately contributing to long-term sustainability and credibility.

An independent Board Chairman could help Ecolab deal with a relative plateau in its stock price. The Ecolab sock price was at $238 in 2021 and only at $255 in late 2025 despite a robust stock market.

An independent Board Chairman could also help Ecolab deal with headwinds like those that emerged in 2025:

Ecolab experienced market softness and declining demand in its Basic Industries and Paper segments, which represent 15% of sales.

Currency translation had a significant unfavorable impact on Ecolab’s financial results throughout 2025. This impact was estimated at 4% on adjusted earnings per share (EPS) growth for the full year.

Ecolab’s reported GAAP (Generally Accepted Accounting Principles) diluted EPS decreased in QI and Q3 of 2025. The Q3 GAAP EPS of $2.05 was down 20% year-over-year.

Ecolab faced capacity limitations in its water purification business, which constrained sales growth in its Life Sciences segment. To mitigate the impact of tariffs and increased supplier costs, Ecolab announced a 5% surcharge for all U.S. customers. This action could potentially affect customer relationships and retention.

Independent Board Chairman — Proposal 4

​

RECOMMENDATION OF THE BOARD OF DIRECTORS

​ ​ ​ After careful consideration, our Board of Directors unanimously recommends that you vote AGAINST this proposal because of our commitment to independent board leadership (including a robust Lead Independent Director role) and the Board’s belief that the Company and our stockholders are best served by a flexible policy that allows the Board to determine the leadership structure that best meets the needs of the Company and its stockholders at any given time. ​

OUR COMMITMENT TO INDEPENDENT BOARD LEADERSHIP

The Board of Directors strongly believes that independent board oversight is vital. As a result, under our corporate governance framework, our Lead Director and independent directors have strong oversight of management and the Company’s governance and effectively oversee management and key issues facing our Company.

Robust Lead Director Role. Our Corporate Governance Principles require an independent Lead Director at any time when the Chairman also holds the office of Chief Executive Officer (“CEO”) or is otherwise not independent.

Our Lead Director is elected annually by a majority of the independent directors after recommendation of the fully independent Governance Committee. The Lead Director has a clearly defined and robust role in managing the Board.

​ ​ Robust Responsibilities and Powers of the Lead Director ▪
Calling meetings of the independent directors. ​ ▪
Presiding over meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors, which occur at every regularly scheduled meeting of the Board. ​ ▪
Acting as a liaison between the Chairman and the independent directors. ​ ▪
Reviewing and approving meeting schedules to assure there is sufficient time for discussion of agenda items. ​ ▪
Reviewing and approving information sent to the directors. ​ ▪
Reviewing and approving meeting agendas and participants at meetings of the Board, as well as seeking Board input on agenda items. ​ ▪
Engaging with stockholders in appropriate circumstances. ​ ​ ​

Our Corporate Governance Principles provide that the Lead Director should rotate every four to six years, which promotes the Lead Director’s independence. David MacLennan has served as our Lead Director since May 2023.

Independent Director Oversight. Currently, all of our directors, with the exception of Mr. Beck, are independent in accordance with the listing standards of the New York Stock Exchange, the rules and regulations of the SEC, applicable law, and the Board’s independence policy. In addition, each of the Audit, Compensation & Human Capital Management, Finance, and Governance Committees is comprised solely of, and chaired by, independent directors. Additionally, the Safety, Health & Environment Committees is comprised of a majority of, and chaired by, independent directors. As a result, independent directors are responsible for overseeing key matters, including, among other items, the integrity of Ecolab’s financial statements, the evaluation of the Board’s and the Committees’ performance, Ecolab’s executive compensation, the nomination of directors, the composition and leadership of each Board committee, and the selection of the Lead Director.

​ 84    CONSISTENT HIGH PERFORMANCE ​ ​ ​ ​

TABLE OF CONTENTS

Stockholder Proposal

This robust independent oversight is supported by strong corporate governance practices.

​ ​ Strong Corporate Governance Practices Further Independent Oversight ▪
Individual directors and Board committees have direct access to Ecolab’s senior management. ​ ▪
The Board and its committees may retain independent advisors and consultants, including the Company’s public accounting firm, compensation consultant, and others. ​ ▪
Our Lead Director chairs executive sessions of independent directors without the CEO present, which occur at every regularly scheduled meeting of the Board. ​ ▪
The Governance Committee leads a review of the Board’s performance and effectiveness each year as well as evaluates the CEO’s performance with feedback from all of the independent directors. ​ ▪
The Governance Committee reviews the structure of the Board annually, including whether the current model of having a combined Chairman and CEO role is in the best interests of the Company and stockholders. ​ ▪
The Governance Committee nominates and recommends to the Board all independent directors, committee chairs and committee members, and the Chairman does not actively participate in the nomination processes. ​ ▪
The Compensation & Human Capital Management Committee reviews and approves the corporate goals and objectives relevant to CEO compensation and sets the CEO’s compensation based on the evaluation of CEO performance in light of those goals and objectives. ​ ▪
Directors are elected annually, offering stockholders an opportunity to provide input on director performance. ​ ​ ​

FLEXIBILITY IN BOARD LEADERSHIP STRUCTURE IS MORE SUITABLE THAN THE PROPOSAL’S PRESCRIPTIVE APPROACH

The Board also strongly believes that stockholders are best served by not having a fixed policy on whether the offices of Chairman and CEO are to be held by one person or not. This allows for the Board to re-evaluate the needs of the Company from time to time and make determinations regarding Board leadership based upon then-existing conditions, including business needs, stockholder preferences and feedback, and individual director skills and experiences. This proposal would remove this flexibility and narrow the governance arrangements that the Board may consider, which could in certain instances be contrary to the best interests of our stockholders.

At Ecolab, the roles of Chairman and CEO were historically combined, and then split when Mr. Beck was first appointed CEO in 2021. The Board’s decision to separate the roles of Chairman and CEO at that time enabled Mr. Beck to assume leadership of the Company while the Chairman and former CEO, Mr. Douglas Baker, managed the duties of Chairman of the Board.

In connection with Mr. Baker’s retirement from Ecolab in May 2022, the Board undertook extensive deliberations regarding the Board’s leadership structure at numerous meetings, including the merits of separating or combining the Chairman and CEO roles and whether the Chairman role should be held by an independent director. The Board gave thorough consideration to a number of factors, including the size and complexity of Ecolab’s business, the Company’s performance and strategy, the composition of the Board, Ecolab’s corporate governance practices, market practice, and Ecolab’s stockholder base and investor views and engaged third party consultants to provide additional insight and enhance the Board’s deliberations. The Board also reflected upon the Company’s strong, independent oversight function exercised by the Board, as well as the independent leadership provided by the independent Lead Director.

After considering these factors and evaluating the leadership, qualifications, and performance of Mr. Beck in his roles as CEO and a director, the Board determined that it was again in the best interests of the Company to combine the roles of Chairman and CEO under Mr. Beck, while preserving the important role of the Lead Director, for the following reasons:

​ ​ ​ ​ ECOLAB PROXY STATEMENT 2026    85 ​

TABLE OF CONTENTS

Stockholder Proposal

​ ​ ▪
the benefits to the decision-making process with a leader who is both Chairman and Chief Executive Officer; ​ ▪
the significant operating experience and qualifications of Mr. Beck, including 18 years at Ecolab where he held leadership roles within the Water, International and Institutional businesses; ​ ▪
the importance of deep Ecolab knowledge in exercising business judgment in leading the Board; ​ ▪
the size and complexity of our business; ​ ▪
the significant business experience and tenure of our independent directors; and ​ ▪
the qualifications and role of our Lead Director. ​ ​ ​

The Board re-evaluates its leadership structure each year and considers whether it remains appropriate. As set out under “Corporate Governance — Board Leadership Structure” on page 25, the Board continues to believe that at this time, combining our CEO and Chairman offices, along with an independent Lead Director, is the most appropriate leadership structure for the Company and best serves the interests of our stockholders for the reasons stated above.

Moreover, the Board believes that the appointment of Mr. Darrell Brown as the Chief Operating Officer of the Company in October 2022 further strengthens Mr. Beck’s ability to serve as CEO and Chairman, as this appointment provides Mr. Beck additional time to address his duties as Chairman and CEO of the Company.

STOCKHOLDERS REJECTED THIS PROPOSAL IN RECENT YEARS

The proponent submitted similar proposals in 2014, 2015, 2019, 2023, and 2024. Our stockholders rejected each of these proposals. In 2024, we reached out to stockholders representing over 50% of our outstanding shares and our stockholders generally supported the current Board leadership structure with a combined Chairman/CEO and a strong independent Lead Director.

In view of our highly independent board structure, strong corporate governance practices and proven track record of success, the Board believes that this stockholder proposal’s rigid approach to our Board leadership structure is not necessary and not in the best interest of our stockholders.

BOARD OF DIRECTORS’ RECOMMENDATION

​ ​ ​ For the reasons stated above, the Board of Directors unanimously recommends that you vote AGAINST this stockholder proposal. Unless a contrary choice is specified, proxies solicited by our Board of Directors will be voted AGAINST the stockholder proposal. ​

As with all proposals, if the stockholder proposal is not properly presented by the proponent at the Annual Meeting, the Company reserves the right not to hold a vote on this proposal at the Annual Meeting.

General Information

How do I Vote My Proxy?

You may vote by submitting a valid proxy prior to the Annual Meeting. We recommend you submit your proxy even if you plan to attend the Annual Meeting. If you attend the Annual Meeting, you may vote during the meeting, thereby canceling any proxy previously submitted.

Voting instructions are included on your proxy card. If you properly complete your proxy and submit it to us in time to be tabulated, one of the individuals named as your proxy will vote your Common Stock as you have directed. You may vote for or against each proposal, or you may abstain from voting on a proposal. With respect to the election of directors, you may vote for or against each nominee, or you may abstain from voting on the election of one or more nominees.

Can I Revoke My Proxy?

You may revoke your proxy at any time before it is voted by:

​ ​ ​ Timely delivery of a valid, later-dated proxy, including a proxy given by telephone or Internet ​ ​ ​ ​ ​ Timely delivery of written notice that you have revoked your proxy to: Ecolab Inc.
Attention: Corporate Secretary
1 Ecolab Place
St. Paul, MN 55102 ​ ​ ​ ​ ​ Attending our Annual Meeting and voting electronically by entering the 16-digit control number found on your proxy card, voting instruction form, or Notice, as applicable ​

QUORUM, ABSTENTIONS, AND BROKER NON-VOTES

What is a Quorum?

A quorum of stockholders is necessary to hold a valid meeting. The presence in person or by proxy at the meeting of holders of a majority of the outstanding shares of Common Stock entitled to vote at the meeting is a quorum. Abstentions and broker non-votes count as present for establishing a quorum. Common Stock held by Ecolab in our treasury does not count toward a quorum.

What does an Abstention Mean?

Shares voted “ABSTAIN” are not counted as votes cast and will have no effect on the proposals to be voted on at the Annual Meeting.

What are Broker Non-Votes?

Broker non-votes occur on a proposal when the beneficial owner of Common Stock does not submit voting instructions to a broker or bank. Under New York Stock Exchange rules, brokers, banks, and other nominees generally will have discretionary authority to vote shares in absence of instructions on “routine” matters and will not have discretion to vote shares on non-routine matters. Broker non-votes, if any, are not counted as votes cast for any purpose in determining whether a matter has been approved. In order for their views to be represented at the meeting, we strongly urge all beneficial owners to provide specific voting instructions on all matters to be considered at the meeting to their record-holding brokers.

Election of director nominees

​

FOR each director nominee

​

​

​

Each nominee will be elected to the Board if they receive a majority of the votes cast. Votes cast with respect to a nominee include votes for or against a nominee and exclude abstentions and broker non-votes. If an uncontested nominee for director does not receive an affirmative majority of FOR votes, he or she is expected to promptly offer his or her resignation to the Board’s independent Governance Committee. That committee will then make a recommendation to the Board as to whether the offered resignation should be accepted or rejected, or whether other action should be taken. The Board will publicly announce its decision regarding the offered resignation and the rationale behind it within 90 days after the election results have been certified. Any director who has so offered his or her resignation will not be permitted to vote on or participate in the recommendation of the Governance Committee or the Board’s decision with respect to his or her resignation.

What is Discretionary Voting?

We are not currently aware of any other business to be acted upon at our Annual Meeting. If, however, other matters are properly brought before the Annual Meeting, or any adjournment or postponement of the Annual Meeting, your proxy includes discretionary authority on the part of the individuals appointed to vote your Common Stock or act on those matters according to their best judgment, including to adjourn the Annual Meeting.

When Can a Meeting Adjournment Occur?

Adjournment of our Annual Meeting may be made for the purpose of, among other things, soliciting additional proxies. Any adjournment may be made from time to time by approval of the holders of Common Stock representing a majority of the votes present in person or by proxy at the Annual Meeting, whether or not a quorum exists, without further notice other than by an announcement made at the Annual Meeting. We do not currently intend to seek an adjournment of the Annual Meeting.

VOTING BY PLAN PARTICIPANTS

How do Plan Participants Vote their Shares?

Generally, you will receive only one notice, proxy card or voting instruction form covering all the shares you hold:

▪

in your own name;

​

▪

in the Dividend Reinvestment Plan sponsored by Computershare Trust Company, N.A., if any; and

​

▪

if you participate in one or more of the following Plans:

​

▪

the Ecolab Savings Plan and ESOP*; or

​

If you participate in the Ecolab Savings Plan and ESOP or the Ecolab Puerto Rico Savings Plan, you are entitled to direct the respective plan trustee to vote (or not to vote) the equivalent number of shares of Common Stock credited to your Plan account. Your proxy card will serve as a voting instruction to the Trustee and if your instructions are timely received, the Trustee will follow your voting instructions. If you do not timely submit your voting instructions, the Trustee will vote your Plan shares in the same proportion as to each respective proposal as the shares for which voting instructions have been received from other Plan participants. To allow sufficient time for voting of your shares by the Trustee, your voting instructions should be received by May 4, 2026, to ensure tabulation.

​

If you hold Ecolab shares through any other Ecolab plans, you will receive voting instructions from that plan’s administrator.

Proxy Solicitation Costs

This proxy is solicited by our Board of Directors. We will bear the cost of the preparation and solicitation of proxies, including the charges and expenses of brokerage firms, banks, or other nominees for forwarding proxy material to beneficial owners. In addition to solicitation by mail, proxies may be solicited by telephone, the Internet or personally. We have retained Innisfree M&A Incorporated, 501 Madison Avenue, 20th Floor, New York, NY 10022, to aid in the solicitation of proxies for a fee of $20,000 plus expenses. Proxies may also be solicited by certain directors, officers, and employees of the Company without extra compensation.

2027 Stockholder Proposals and Director Nomination

​ Stockholder Proposals for Inclusion in the Proxy Statement for the 2027 Annual Meeting ​

If a stockholder wishes to have a proposal formally considered at the 2027 Annual Meeting of Stockholders and included in the Company’s Proxy Statement for that meeting, the proposal must be received by the Corporate Secretary at our headquarters no later than November 23, 2026, and must comply with the other requirements of Rule 14a-8 under the Securities Exchange Act of 1934. The submission of a stockholder proposal does not guarantee that it will be included in the proxy statement.

​ Director Nominations for Inclusion in the Proxy Statement for the 2027 Annual Meeting ​

The Board has implemented a proxy access provision in our By-Laws, which allows a stockholder or group of up to 20 stockholders owning in aggregate 3% or more of our outstanding Common Stock continuously for at least three years to nominate and include in our proxy materials director nominees constituting up to 20% of the number of directors in office or two nominees, whichever is greater, provided the stockholder(s) and nominee(s) satisfy the requirements in the By-Laws. If a stockholder or group of stockholders wishes to nominate one or more director candidates to be included in the Company’s Proxy Statement for the 2027 Annual Meeting of Stockholders pursuant to these proxy access provisions in our By-Laws, proper written notice of any such nomination must be received by the Corporate Secretary at our headquarters no earlier than the close of business on October 24, 2026, and no later than the close of business on November 23, 2026, and the nomination must otherwise comply with our By-Laws.

​ Other Proposals for Director Nominations for Presentation at the 2027 Annual Meeting ​

Under our By-Laws, if a stockholder wishes to present other business or nominate a director candidate at the 2027 Annual Meeting of Stockholders without seeking to have the matter included in the proxy materials, proper written notice (including information required under Rule 14a-19) of any such business or nomination must be received by the Corporate Secretary at our headquarters no earlier than the close of business on December 8, 2026, and no later than the close of business on January 7, 2027. If, however, the 2026 Annual Meeting is not within 30 days before or after the anniversary of this year’s Annual Meeting, such notice must be received by the Corporate Secretary at our headquarters no later than the close of business on the 10th day following the day on which such notice of the date of the annual meeting was mailed or public disclosure of that date was made, whichever occurs first. If a stockholder does not meet these deadlines or does not satisfy the requirements of Rule 14a-4 of the Exchange Act, the persons named as proxies will be allowed to use their discretionary voting authority when and if the matter is raised at the Annual Meeting.

Cautionary Note about Forward-Looking Statements

This Proxy Statement contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. In particular, statements that are not historical facts, including but not limited to, statements about our anticipated financial results, capital development and growth, as well as about the development of our products, markets, and workforce, are forward-looking statements. These forward-looking statements are generally identifiable by use of the words “believe,” “expect,” “intend,” “anticipate,” “estimate,” “project” or similar expressions, whether in the negative or affirmative. Forward-looking statements are based on our current plans, expectations, and assumptions and are not guarantees of future performance. Information about factors that could cause actual results to differ materially from those in the forward-looking statements can be in Ecolab’s Annual Report on Form 10-K, Forms 10-Q, and other filings with the U.S. Securities and Exchange Commission. We caution readers not to place undue reliance on any forward-looking statements, which only speak as of the date made. We undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made.

Forward-looking and other statements in this document may also address our sustainability initiatives, goals, targets and progress, and the inclusion of such statements is not an indication that these contents are necessarily material to investors or required to be disclosed in our filings with the SEC. In addition, historical, current, and forward-looking sustainability-related statements may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future and performance against our goals and targets may differ from such forward-looking statements in such event.

The Board of Directors is not aware of any matters to be presented at the Annual Meeting other than those set forth in this Proxy Statement.

APPENDIX A​

Reconciliation of Non-GAAP Financial Measures

This Proxy Statement includes financial measures that have not been calculated in accordance with U.S. GAAP. These non-GAAP measures include organic sales, organic operating income margin and adjusted diluted EPS. We provide these measures as additional information regarding our operating results. We use these non-GAAP measures internally to evaluate our performance and in making financial and operational decisions, including with respect to incentive compensation. We believe that our presentation of these measures provides investors with greater transparency with respect to our results of operations and that these measures are useful for period-to-period comparison of results.

These non-GAAP measures are not in accordance with, or an alternative to U.S. GAAP and may be different from non-GAAP measures used by other companies. You should not rely on any single financial measure when evaluating our business. We recommend that investors view these measures in conjunction with the U.S. GAAP measures, and we have provided reconciliations of reported U.S. GAAP amounts to the non-GAAP amounts below.
