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

DEAR FELLOW STOCKHOLDER:

2023 was a year of milestones and momentum for Ecolab.

After achieving the rare honor of 100 years in business, our team of 48,000 associates went on to deliver for customers across more than 170 countries worldwide. They made 2023 our best year yet, while strengthening Ecolab’s connections with customers, partners and communities, and upholding our rich history of making the world cleaner, safer and healthier.

Our Global Industrial team reinforced Ecolab’s position as the world’s water company by helping customers deliver critical business, water and sustainability outcomes. The Institutional & Specialty team returned to its rightful place as a significant driver of Ecolab’s business, as they helped newly energized hospitality and retail customers thrive. The Healthcare & Life Sciences team continued their work to build a growth engine for the future. And our Pest Elimination team combined science-based service and expert innovation to grow at a historic pace.

Even as inflationary pressures elevated raw material, energy and transportation costs, our team worked to prove the total value delivered to customers. Their combined efforts allowed Ecolab to report historically impressive levels of new business and sales growth. That is why we finished 2023 with great momentum and full of confidence for the year ahead.

We believe that doing the right thing, the right way, is good for business. We achieved record associate engagement scores, made Ecolab safer and more inclusive, and demonstrated solid progress on our sustainability targets. And in 2024, we were once again recognized as the world’s most admired company in our industry and as one of the world’s most ethical companies for the 18th consecutive year.

2023 was a year of milestones and momentum for Ecolab. It is thanks to our global team of associates that we continue to​

grow fast and drive performance, while making a net positive impact on the world.”

These achievements are the result of all we’ve done in recent years to protect our team, our customers, and our Company. Through it all, Ecolab has remained focused on delivering strong returns for our stockholders. In 2023, we returned $604 million in cash dividends, while also investing in our business to support future growth. Our excellent cash flow and strong business momentum allowed us to announce our 32nd annual cash dividend rate increase and continue our 87-year run of common stock cash dividends.

I look forward to sharing more detailed updates on these and other matters 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 12:30 p.m. Central Time on May 2, 2024 and make your vote count. To attend, vote and submit questions, please visit www.virtualshareholdermeeting.com/ECL2024 and enter the 16-digit control number found in your Notice of Internet Availability of Proxy Materials, voting instruction form or proxy card.

As Chairman and CEO of Ecolab, I am excited about our Company’s bright future and the positive impact we can continue to make on the world. I want to thank you for your investment and your ongoing belief in our team.

We can all be proud of Ecolab’s last 100 years, and I am confident that together, we can make our next century even better.

Sincerely,

Christophe Beck
CHAIRMAN AND CEO

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 2, 2024. Here you will be able to vote on stockholder proposals, hear important updates about 2023 and how we successfully managed a year of continued business growth.

It was in 2023 that I was elected as Ecolab’s lead independent director, replacing Jeffrey M. Ettinger. I would like to acknowledge Jeff and the many contributions he made to Ecolab’s Board as my predecessor. While I bring different experiences and insights to the position, I am also focused on delivering long-term value for our stockholders.

In 2024, we were excited to welcome Judson Althoff to the Board. His global business and high-tech experience make him an excellent addition and we are sure to benefit from his artificial intelligence and cloud computing knowledge. We also thank our valued colleague, Barbara J. Beck, for her service, including in her roles as Chair of the Governance Committee and the Compensation & Human Capital Management Committee.

As I look back on the previous year, your independent directors were deeply involved in the development and oversight of Ecolab’s business strategy. We focused on the successful assessment and mitigation of Company risk, including the management of financial, business and sustainability risk. We also oversaw a renewed focus on cementing the Company’s status as an innovation powerhouse. By focusing on market, enterprise and breakthrough innovations, we see Ecolab addressing critical customer needs and realizing significant new sales opportunities in the coming years.

I have personally worked closely with our Chairman & CEO to maintain effective working relationships between the independent directors and Ecolab’s management. I also take very seriously the responsibility of reviewing and supporting the effectiveness and independence of your Board of Directors. As Chair of the Governance Committee, I have also led ongoing efforts to maintain strong Board leadership, composition and refreshment.

Ecolab’s last century was characterized by​ innovation, growth and positive impact.​

The Company has the strategy and leadership in place to continue this momentum and deliver strong returns for its stockholders.”

It is the combined effect of this work that makes me proud of Ecolab’s continued progress in 2023. This is the message that I shared as I represented your interests in many stockholder engagements during the year. These conversations were often focused on Ecolab’s executive compensation, governance structure, board composition and refreshment, and the oversight of risk.

If these topics are also of interest to you, I invite you to review the updates and ongoing changes overseen by the Board’s committees, including the Compensation & Human Capital Management Committee.

I would also like to thank you, our stockholders, for your continued confidence and investment in Ecolab. Your support underpins our commitment to continued progress and innovation in the pursuit of sustainable long-term value creation.

Sincerely,

David W. MacLennan
LEAD INDEPENDENT DIRECTOR

	Organic sales grew 9% with all segments delivering growth.		Innovation continues to drive our growth and in 2023, we launched a robust pipeline of new innovative programs including Ecolab Water for Climate. This program helps industrial customers address their need for greater water and energy efficiency while also addressing our planet’s need for more sustainable operations.
	This strong performance reflected continued robust 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.
	Our team generated double-digit sales growth in the Institutional & Specialty and Other segments while our Industrial and Healthcare & Life Sciences segments delivered good growth.		We generated double-digit operating income growth as strong pricing overcame investments in the business (including incentive compensation), unfavorable mix, and higher supply chain costs.

OUR COMMITMENT TO CORPORATE RESPONSIBILITY AND LEADERSHIP

100 YEARS OF INNOVATION	48,000​ ASSOCIATES	40​ INDUSTRIES	170+​ COUNTRIES	1,200+​ SCIENTISTS	1,000+​ DIGITAL EXPERTS

OUR APPROACH

The Board uses a framework for key risks and opportunities considered to be most relevant to our long-term sustainability. This framework aligns with 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.

ECOLAB PROXY STATEMENT 2024      3

Proxy Summary

THE FOUR PILLARS FROM THE WEF REPORT “MEASURING STAKEHOLDER CAPITALISM: TOWARDS COMMON METRICS AND CONSISTENT REPORTING OF SUSTAINABLE VALUE CREATION”
PRINCIPLES OF GOVERNANCE​	PLANET​	PEOPLE​	PROSPERITY​
The definition of governance is evolving as organizations are increasingly expected to define and embed their purpose at the center of their business. But the principles of agency, accountability, and stewardship continue to be vital for truly “good governance.”	An ambition to protect the planet from degradation, including through sustainable consumption and production, sustainably managing its natural resources and taking urgent action on climate change, so that it can support the needs of the present and future generations.	An ambition to end poverty and hunger, in all their forms and dimensions, and to ensure that all human beings can fulfil their potential in dignity and equality and in a healthy environment.	An ambition to ensure that all human beings can enjoy prosperous and fulfilling lives and that economic, social and technological progress occurs in harmony with nature.

Source: https://sustainabilityknowledgegroup.com/measuring-stakeholder-capitalism/

BOARD OVERSIGHT

Our Board has oversight of these efforts primarily through the Safety, Health and Environment (“SH&E”) Committee, which (as stated in the SH&E Committee Charter) is responsible 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 Corporate Sustainability Team, which monitors the risks and opportunities related to climate change, 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 on the implementation of and progress against sustainability and climate-related goals and activities from the Senior Vice President and Chief Sustainability Officer who leads the Corporate Sustainability team, and other members of management.

For example, the SH&E Committee’s sustainability reviews include: overall climate-related risks and progress towards the UN Global Compact Business Ambition for 1.5°C, and actions to implement the recommendations of the Task Force on Climate-related Financial Disclosures (“TCFD”) (or similar bodies), including whether the Company has set GHG emissions targets in line with the Business Ambition for 1.5°C and to achieve net-zero emissions before 2050.

The Board receives an annual presentation from the SH&E Committee on our progress against our sustainability goals, and implementation of projects and related activities, which includes management of water and climate-related issues, as appropriate. The SH&E Committee discusses these matters with the Board, which contributes to the Board’s oversight of sustainability and climate-related issues. In 2023, the SH&E Committee received updates on Ecolab’s climate-related risk and opportunity assessment, undertaken in alignment with best practices of the TCFD, the results of which are currently being used to develop adaptation and mitigation plans for relevant climate change risks. 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.

RECENT ACCOMPLISHMENTS

Environmental Stewardship

In 2023, management reported to the SH&E Committee regarding Ecolab’s progress towards its climate and water impact goals, including a step towards sourcing the electricity needs for our European sites through a renewable energy partnership with asset management firm Low Carbon, and our progress in improving the water efficiency of operations, reducing wastewater and mitigating water risks. Management also reported to the SH&E Committee regarding Ecolab’s program for monitoring key biodiversity areas. We have made great progress toward our Net Positive Water Impact and carbon emissions reduction goals while supporting a diverse and inclusive workforce and prioritizing safety in everything we do.

Here are some highlights:

	At the 2023 UN Water Conference in New York, we participated in the Open Call to Accelerate Action on Water, joining other private sector companies in a commitment to make a collective positive impact in 100 basins supporting over 3 billion people by 2030 — a key contribution to the UN’s Water Action Agenda.		We affirmed our commitment as a founding member of the Water Resilience Coalition (WRC) to work collectively to achieve Net Positive Water Impact through public/private partnerships, policy, technology, and a roadmap to reach the WRC’s goals for 100 priority basins by 2030. Through the work of the WRC, we know that 150 companies can directly impact approximately one-third of the world’s water use, which means that industry has a unique responsibility and opportunity to address the global water crisis.
	We joined Starbucks, Gap, Inc., Reckitt, and DuPont and the U.S. International Development Finance Corporation in investing nearly $140 million in the WaterEquity Global Access Fund IV. The fund aims to reach up to 5 million people with access to water, sanitation and hygiene and targets households in at least eight countries in South and Southeast Asia, sub-Saharan Africa, and Latin America.		As part of our efforts to reach Net Positive Water Impact, we achieved Alliance for Water Stewardship (AWS) certifications at two Ecolab facilities, bringing our total AWS-certified facility count to eight across Brazil, Mexico, and the U.S.

Social Responsibility

We have a long-standing belief that a diverse, equitable, and inclusive workforce is a strong foundation for the shared success of our employees, company, customers, and communities. To build that strong foundation, we have worked to embed diversity and inclusion throughout our people processes, including in the areas of recruitment, retention, and development. We strive to provide equitable employment opportunities for people of all backgrounds.

We primarily engage with the communities in which we operate through the Ecolab Foundation. Since 1986, the Ecolab Foundation has implemented community impact programs to support communities where our employees live and work, focusing on giving to local non-profit organizations in the areas of:

▪ youth and education	▪ arts and culture
▪ civic and community development	▪ environment and conservation

Our Board reviews our major governance policies, practices and processes regularly in the context of current corporate governance trends, investor feedback, regulatory changes and recognized best practices.

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 have engaged with over 2,000 investors during 2023 on a variety of topics in a number of forums including quarterly earnings calls, investor and industry conferences, roadshows, analyst meetings, our annual corporate sustainability conference and biennial Investor Day, and individual corporate governance and sustainability-related discussions with stockholders. In 2023, our Lead Independent Director and the Chair of our Compensation & Human Capital Management Committee also participated in conversations with some of our largest stockholders when appropriate.

Proxy Summary

WHO PARTICIPATED​
▪ Lead Independent Director ▪ Compensation & Human Capital Management Committee Chair ▪ Senior Management ▪ Investor Relations ▪ Corporate Secretary

WHAT WE HEARD	HOW WE RESPONDED
Long Term Incentives ▪ All of the stockholders who engaged with us asked about the composition of the equity awards granted to our NEOs and several suggested we more heavily weight performance-based restricted stock units (“PBRSUs”) to place a stronger emphasis on the performance goals underlying these awards. ▪ While stockholders generally demonstrated support for the use of an ROIC metric, a few stockholders expressed a preference for using multiple performance measures for PBRSUs, rather than a single performance measure. ▪ Some stockholders suggested including reasonable “stretch” performance metrics, with upside for executives who exceed the target goals, in order to drive superior performance. ▪ Some of our stockholders asked for more information about the rationale for specific larger, special equity awards.	▪ In response to feedback, the Compensation & Human Capital Management Committee revised the design of the equity awards granted in December to: ▪ Increase the relative weighting of PBRSUs to 60% of target equity award opportunity, with stock options making up the remaining 40%. ▪ Add a relative total stockholder return (“TSR”) modifier to the PBRSUs, which may increase or reduce the payout percentage based on our 3-year TSR compared to the S&P 500. ▪ Modify the ROIC metric for the PBRSUs and add stretch goals to the PBRSU program, allowing for above-target payouts for overperformance, with a cap at 200%. ▪ We provided enhanced disclosure about the special retention equity award made in 2023 to a named executive officer.
Annual Cash Incentives ▪ Numerous stockholders that we spoke with commented that they would like the Management Incentive Plan (“MIP”) to include metrics that reflect the achievement of sustainability goals and progress towards our aspirations for creating a diverse, equitable and inclusive workplace for all associates.	▪ The MIP for 2023 incorporates a Growth & Impact modifier which provides for a potential adjustment based on the achievement of water impact and progress towards our aspirations for creating a diverse, equitable, and inclusive workplace for all associates.
Governance Board and Leadership Structure ▪ Most of our stockholders asked about the role of the Lead Independent Director, and stressed their view that the lead independent director must play a strong role and have responsibilities designed to further the independence of the Board. ▪ While the majority of our stockholders support the current Board leadership structure that has a combined Chairman/​CEO and Lead Independent Director, many of our stockholders asked for information about the process the Board uses to assess its leadership structure.	▪ We provided information about the Lead Independent Director’s duties, as are outlined in our Corporate Governance Principles, and as described more fully in the Board Leadership Structure section on page 23. The Lead Independent Director participated in calls with stockholders representing nearly 35% of Ecolab’s outstanding stock, further demonstrating the Board’s independence. ▪ We discuss the Board’s annual process for evaluating its leadership structure on page 23.
Other Governance Items ▪ Some stockholders asked about the Board’s refreshment efforts, including how the Board achieves balanced tenure. ▪ We have some very experienced Board members, with extensive public company Board experience. Some stockholders asked about balancing director commitments. ▪ Stockholders expressed support for our sustainability focus and the resources we direct towards attracting, retaining and developing our employees.	▪ Our Lead Independent Director, who is also the Chair of our Governance Committee, participated in some of these discussions, and shared that the refreshment process is led by the Governance Committee. More detail is found on page 12. We also updated information about our Board members’ experience, expertise and skills to highlight each director’s contributions to the Board. ▪ Our Lead Independent Director shared that our directors all remain highly engaged and committed. More information about their participation in Board and Committee meetings is available on page 31 of this Proxy Statement. ▪ We remain committed to our sustainability focus and to creating an engaging and inclusive culture.

Proxy Summary

COMPENSATION ELEMENT	2023 ACTIONS AND RESULTS
BASE SALARIES	▪ Our CEO’s base salary increased to $1,300,000 effective April 1, 2023, in continuation of the phased increase of his base salary to the market median level. ▪ Merit increases to base salaries for our other NEOs for 2023 were between 5.7% and 6.8%.
ANNUAL CASH INCENTIVES	▪ Our CEO received a bonus payout which was capped at 200% of target as a result of achieving adjusted diluted EPS above the maximum performance level. ▪ Our COO received a bonus payout at 199% of target based 30% on our enterprise goal achievement and 70% on our adjusted diluted EPS achievement. Our CFO and our General Counsel each received a bonus payout at 199% of target based 30% on achieving individual goals and 70% on adjusted diluted EPS achievement. Our EVP Supply Chain received a bonus payout at 197% of target based 35% on adjusted diluted EPS achievement, 35% on the enterprise goal achievement, and 30% on achieving individual goals. These bonus payouts also include the Growth & Impact modifier described below. ▪ A Growth & Impact modifier was added to the 2023 annual cash incentive program based on Company performance against water impact goals and Ecolab’s aspirations for creating a diverse, equitable and inclusive workplace for all associates. This modifier paid out at 6% and is considered in the bonus payouts for each of the NEOs, other than the CEO, whose award was capped at 200%.
LONG-TERM INCENTIVES	▪ 60% of long-term equity incentive awards consisted of PBRSUs and 40% consisted of stock options. The overall target values of these awards were within the median range of our size-adjusted competitive market for each NEO, other than Mr. Duijser. ▪ The design of the PBRSUs granted in December 2023 for the 2024-2026 performance period was revised to: ▪ Utilize organic ROIC performance measure, rather than the adjusted ROIC performance measure utilized in previous years; ▪ Incorporate a maximum performance payout of 200% for overperformance; and ▪ Include a relative TSR modifier. ▪ The 2021 to 2023 PBRSUs paid out at 100% of target award opportunities based upon adjusted ROIC performance.

We believe that our long-term equity incentive program, which typically accounts for at least half of our NEOs’ total annual compensation, is an effective tool in aligning our executives’ interests with those of our stockholders and in incentivizing long-term value creation.

Target compensation mix does not include any grants of special long-term equity incentives. For more information on our compensation philosophy and process, see page 46.

Corporate Governance and Board
Matters​

PROPOSAL 1 — ELECTION OF DIRECTORS The Board of Directors recommends a vote FOR the election of each of the 12 nominees named in this Proxy Statement to a one-year term ending in 2025.

DIRECTOR NOMINEES

The Governance Committee of our Board of Directors has nominated the 12 persons named on the following pages for election at the 2024 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 elected by stockholders at the 2023 Annual Meeting, except for Mr. Althoff, who was elected to the Board effective February 22, 2024, and was initially referred by a non-management director, recommended by the Governance Committee and interviewed by the independent members of the Board. We would like to thank our valued colleague, Barbara J. Beck, who is not standing for re-election, for her service on the Board, including in her roles as Chair of the Compensation & Human Capital Management Committee and past Chair of the Governance Committee.

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 Committee also will consider 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, the Governance Committee will identify, evaluate and nominate candidates for election or reelection to the Board who possess the following qualifications:

▪

the highest standards of personal and professional integrity

▪

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

▪

background, experience and expertise relevant to our business and that will contribute to the overall effectiveness and diversity of the Board, including diversity of race, ethnicity, gender and sexual orientation

▪

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. Our Board of Directors currently consists of 13 members. Effective as of the Annual Meeting, the size of our Board of Directors will be reduced to 12 members.

Corporate Governance and Board Matters

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 2023 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 of Directors. Our Board strongly believes that Mr. Zillmer has demonstrated, and will continue to demonstrate, his ability to devote the sufficient time and capacity needed to carry out his obligations as a Board member for Ecolab including in his role as a member of the Compensation & Human Capital Management and Finance Committees. After thorough consideration and assessment of Mr. Zillmer’s ongoing performance as an Ecolab Board member including Board evaluations submitted by each independent director, the Board unanimously recommends the re-election of Mr. Zillmer at the Annual Meeting.

The Board considered that Ms. Beck was not standing for re-election at the Annual Meeting and determined to approve changes to certain Committees to balance the membership and expertise on such Committees following her departure. The Board determined that following the Annual Meeting, (i) Ms. McKibben will be appointed a member of the Compensation & Human Capital Management Committee and the Governance Committee and will no longer sit on the Audit and Finance Committees; (ii) Mr. MacLennan will be appointed to the Compensation & Human Capital Management Committee and will no longer sit on the Audit Committee, and (iii) Mr. Green will be Chair of the Compensation & Human Capital Management Committee.

The Board of Directors 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.

CORPORATE GOVERNANCE

OVERVIEW

Our Board of Directors and our senior leadership team believe that strong and effective corporate governance is essential to our overall success. The Board is committed to maintaining a corporate governance structure that promotes long-term stockholder value and supports Ecolab’s policies and programs that affect, or could affect, our employees, customers, stockholders, and neighboring communities. Our Board reviews our major governance policies, practices and processes regularly in the context of current corporate governance trends, investor feedback, regulatory changes and recognized best practices. The following table provides an overview of our corporate governance structure and processes, including key aspects of our Board operations.

CORPORATE GOVERNANCE BEST PRACTICES
BOARD CONDUCT & OVERSIGHT		INDEPENDENCE & PARTICIPATION		STOCKHOLDER RIGHTS
	Regular engagement with management on business strategy and approval of annual strategic plan		11 of 12 director nominees are independent based on New York Stock Exchange (“NYSE”) standards		Proxy access on market terms
	Corporate governance policies addressing retirement age		Executive sessions of independent directors held at each Board and committee meeting		Stockholder ability to request special meetings at 25% threshold
	Recently refreshed Code of Conduct that applies to all directors, executive officers, and employees		Lead director with robust duties		Stockholders can act by written consent
	Periodic review of corporate governance best practices and developments		Directors attended over 98% of the meetings of the Board and the committees on which they served		Majority voting in uncontested director elections with a director resignation policy
	Significant time devoted to succession planning and leadership development		Regular Board refreshment and mix of tenure of our directors (4 of the current independent directors elected in the last 5 years)		No “poison pill”
	Annual Board and committee evaluations		Periodic refreshment of committee chairs and Lead Director		The Certificate and Bylaws do not include supermajority voting requirements to amend

More details are available in our Corporate Governance Principles, which can be found on our website at www.investor.ecolab.com/​
corporate-governance.

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 are independent. The Board of Directors also previously affirmatively determined that Barbara J. Beck, who is not standing for re-election, is independent and that Jeffrey M. Ettinger, who resigned from the Board effective May 23, 2023, 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 Chairman and Chief Executive Officer and his former status as President and Chief Operating 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

▪

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.

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 17 years at Ecolab where he held leadership roles within the Industrial, 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

▪

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 oversight of risk management and sustainability matters. 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	ANNUAL IT SECURITY TRAINING & COMPLIANCE
▪ Conducted by an 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: ▪ 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. An 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 as a whole. The Board addressed 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 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. 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.

The Company is formally assessed by an independent third party against the National Institute of Technology (“NIST”) Cyber Security Framework (“CSF”) and industry standards, including peer benchmarking.

The Company also operates an information security training and compliance program for personnel, as well as monthly awareness campaigns and testing and business resiliency training and drills with our supply chain and other key functions. For more information, refer to the “Cybersecurity” section of our Annual Report on Form 10-K, at page 21.

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/corporate-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 shareholders. 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 reviews Ecolab’s policies and practices relating to trade association memberships. More information on Ecolab’s trade association memberships is available at www.investor.ecolab.com/corporate-governance/trade-associations.

To be considered by the Governance Committee for the 2025 Annual Meeting, a director candidate recommendation must be received by the Corporate Secretary by January 2, 2025. 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 5 meetings of the Board of Directors during the year ended December 31, 2023. Overall attendance by all directors at meetings held by the Board and all Committees on which they served was over 98%. Each director attended 100% of the Board meetings and at least 94% of meetings held by the Board and all Committees on which he or she 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 four non-employee, independent directors: Ms. Beck (Chair) and Messrs. Green, Higgins 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. Our practices and procedures for identifying transactions with related persons are located in the charter of the Governance Committee. 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 2023, nor any currently anticipated transactions.

DIRECTOR COMPENSATION FOR 2023

During 2023, members of the Board of Directors who are not employees of the Company were entitled to receive the following compensation:

ADDITIONAL SUPPLEMENTAL RETAINERS FOR SELECT BOARD SERVICE ($)
Lead Director	​	35,000
Committee Chairs:
▪ Audit Committee	​	25,000
▪ Compensation & Human Capital Management Committee	​	20,000
▪ Finance Committee	​	20,000
▪ Governance Committee	​	20,000
▪ Safety, Health & Environment Committee	​	20,000
▪ Audit Committee Member	​	10,000

The base annual compensation of $300,000 per year, excluding committee retainers, is within the median range of our competitive market, as is the total equity compensation of $180,000 comprising a portion of such base. 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.

All reasonable travel and other expenses incurred by directors on behalf of Ecolab were reimbursed.

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 2001 Plan awards denominated in shares that may be made to any non-employee director of the Company 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 grants are granted on the date of the Annual Meeting of Stockholders and vest in 25% installments three, six, nine and twelve months, respectively, after the grant date. A director appointed after the annual meeting will receive a pro rata grant at 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 following cessation of Board service pursuant to the director’s distribution election for deferred stock units in the director’s deferral plan.

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. 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.

STOCK RETENTION AND OWNERSHIP GUIDELINES

Our stock retention and ownership guidelines encourage our directors to accumulate a significant ownership stake in the Company so they are incentivized to maximize long-term stockholder returns. 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, the director is expected to 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 in the director’s deferral plan count towards meeting the guidelines. Unexercised stock options do not count towards the guidelines. Our directors may not pledge shares or enter into any risk hedging arrangements with respect to Company stock. Our directors are 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 after-tax profit shares from any stock option exercises.

CHANGES EFFECTIVE IN 2024

The 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, 2024:

▪

Increased the annual cash retainer from $120,000 to $125,000;

▪

Increased the annual deferred stock unit award from $125,000 to $135,000; and

▪

Increased the supplemental retainer for the Lead Director from $35,000 to $40,000.

We retained all of the other components of our non-employee director compensation program, including the annual stock option grant with a grant date fair value of $55,000 and the retainers of the committee chairs and the Audit Committee members, without change. The changes to the annual retainer and stock unit awards increase total annual compensation from $300,000 per year to $315,000 per year, excluding committee retainers, which is within the median range of our competitive market as previously defined at page 32 of this Proxy Statement. Prior to these changes, the compensation amounts under the program were last changed effective as of January 1, 2022.

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 2023 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 2023 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 2025 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. Proxies solicited by our Board of Directors will be voted FOR approval of the proposal unless otherwise specified.

Non-GAAP financial measures are described in our 10-K for fiscal year 2023: Organic Sales Growth, page 31; Organic OI Margin Expansion, page 34; Adjusted Diluted EPS Growth, page 36.

In 2023, Ecolab delivered very strong performance despite continued soft macro demand. Organic sales grew 9% and organic operating income margin expanded by 140 basis points, resulting in 16% growth in adjusted diluted earnings per share (hereinafter “adjusted EPS” or “adjusted diluted EPS”). These achievements are the result of the work done over the last few years to strengthen Ecolab’s key long-term growth drivers, enabling the Company to grow fast and drive performance while making a positive impact.

Executive Compensation

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 the businesses in order to achieve attractive, long-term shareholder returns.

As a result of our 2023 performance, payouts under our MIP versus our pre-established performance goals were achieved at 200% of target for corporate performance (adjusted EPS), and 160% of target for the enterprise goal (which includes both adjusted EPS and the commercial average components), as illustrated below. The Growth & Impact modifier was achieved at 6%.

Adjusted Diluted EPS is a non-GAAP financial measure that is described on page 50 under “Program Elements — Annual Cash Incentives.”

Commercial Average is a component of the Enterprise Goal, which also includes an adjusted EPS component. The Enterprise Goal was achieved at 160% and is described in more detail on page 50 under “Program Elements — Annual Cash Incentives.”

In connection with Mr. Beck’s appointment as Chief Executive Officer effective January 1, 2021, the Compensation & Human Capital Management Committee initially positioned Mr. Beck’s total direct compensation (“TDC”) below the market median range, with the intent to gradually increase towards median over the following years, subject to Mr. Beck’s performance. Accordingly, 2023 TDC for our CEO represents a 20% increase over 2022 but remains 6% below the market median, reflecting the Company’s approach to increase toward the median over a three to four year period. The following reflects each component of Mr. Beck’s TDC for 2023, as well as his aggregate target TDC for 2021, 2022 and 2023 and the relation of his target TDC to market median:

Executive Compensation

In addition to reviewing TDC, the Compensation & Human Capital Management Committee annually evaluates how total cash compensation paid aligns with the Company’s size and performance relative to the Company’s peer group, which is described in more detail under “Compensation Philosophy and Process — Compensation Benchmarking” below. For purposes of this analysis, composite size and performance is calculated based on various measures of company size, profitability, growth, and total shareholder return. Total cash compensation paid represents the sum of actual base salary and annual cash incentive paid to our CEO for each fiscal year. The chart below illustrates how total cash compensation paid to our CEO has been conservative relative to the Company’s size and performance over the last three years.

Compensation Practices

WHAT WE DO

WHAT WE DON’T DO

▪ We pay annual cash compensation to the NEOs that is conservative for our composite size and performance over the last five years relative to our peer group ▪ We grant long-term equity incentives at levels informed by market, including our peer group and other companies directly competing for our talent, using a portfolio of stock options and PBRSUs ▪ We provide an appropriate balance of short- and long-term compensation, with payouts based on our achievement of certain financial metrics and specific business objectives ▪ Our PBRSUs vest based on average annual adjusted ROIC (or organic ROIC, commencing with 2023 awards) goals over a three-year performance period ▪ We maintain maximum payout caps for annual cash incentives and long-term performance awards ▪ We have a robust stock ownership policy for officers ▪ We maintain clawback policies that go beyond minimum NYSE listing standard requirements ▪ We solicit annual “say-on-pay” stockholder votes

▪ We don’t have excessive perquisites for any of our NEOs ▪ Our compensation programs don’t encourage excessive risk-taking ▪ Our Insider Trading Policy prohibits certain short-term or speculative transactions by insiders in Company securities ▪ We don’t permit hedging or pledging of Company stock ▪ We don’t offer “single trigger” change in control benefits ▪ We don’t provide change-in-control tax gross-ups ▪ We don’t individually negotiate employment agreements with our NEOs

Say-on-Pay Results and Stockholder Outreach

At the 2023 Annual Meeting, the advisory vote on the compensation of our NEOs was approved with the support of just over 67% of the total votes cast, reflecting a decrease in the support demonstrated in prior years. Although the advisory vote received the support of well over a majority of the votes cast, the Compensation & Human Capital Management Committee, the full Board, and management were disappointed with this decline in support and took the voting outcome seriously.

After publishing our 2023 Proxy and before the 2023 Annual Meeting, we commenced a targeted shareholder outreach campaign to better understand our stockholder’s perspectives on our compensation program. We continued these efforts after the 2023 Annual Meeting. Throughout the spring outreach and late summer/fall outreach, we contacted stockholders holding approximately 53% of our shares and held meetings with stockholders holding approximately 48% of our shares. Our Lead Independent Director or the Chair of our Compensation & Human Capital Management Committee attended several of these meetings, having conversations with stockholders representing almost 36% of our shares. While stockholders generally supported the overall structure of our compensation program, we received some constructive feedback relating to the design of certain elements of our compensation program. We listened and have implemented program changes, where the Compensation & Human Capital Management Committee determined appropriate, to address this feedback.

WHAT WE HEARD	HOW WE RESPONDED
Long-Term Incentives ▪ All of the stockholders who engaged with us asked about the composition of the equity awards granted to our NEOs. Some stockholders expressed a preference to shift the historical weighting of stock options and PBRSUs (50% each) towards a higher weighting of PBRSUs, to place a stronger emphasis on the performance goals underlying these awards. ▪ While stockholders generally demonstrated support for the use of an ROIC metric, a few stockholders expressed a preference for using multiple performance measures for PBRSUs, rather than the single performance measure used historically (Adjusted ROIC). ▪ Some stockholders indicated that the Company’s historical achievement of the Adjusted ROIC metric applicable to the PBRSUs, as compared to Company performance, suggested that there may be value in incorporating reasonable “stretch” performance goals, with upside for executives who exceed the target goals, in order to drive performance. ▪ Some of our stockholders asked about the rationale for specific larger, special equity awards. Most of these stockholders agreed that such grants, including time-based grants, can be appropriate under the right circumstances, but indicated that they would like more information to enable them to assess the reasonableness of specific grants.	Long-Term Incentives ▪ In response to feedback, the Compensation & Human Capital Management Committee revised the design of the equity awards granted in December as follows: ▪ Increased the relative weighting of PBRSUs to 60% of each NEO’s target equity award opportunity, with stock options making up the remainder. ▪ Shifted from a 3-year average Adjusted ROIC metric for the PBRSUs to a 3-year average Organic ROIC metric, which excludes the impact of acquisitions and certain other adjustments as described starting on page 53 under “Long-Term Equity Incentives” during the performance period. This metric aligns the ROIC calculation with the industry standard. Target Average Organic ROIC goals for the three-year performance period were set at levels that would require significant year-over-year organic growth and focus our management team on our long-term fundamentals. ▪ Added a relative total shareholder return (“TSR”). modifier to the PBRSUs, which may increase or reduce the payout percentage based on our 3-year TSR compared to the S&P 500. If our relative TSR performance is in the 80th percentile or higher, the payout percentage will be increased by 10% and if relative TSR performance is in the 20th percentile or lower, the payout percentage will be decreased by 10%. No modification occurs for relative TSR performance between these percentiles. ▪ Added stretch goals to the PBRSU program, allowing for above-target payouts for overperformance, with payouts ranging from 40% for threshold performance to 200% for maximum performance. The payout opportunity for the 2023 PBRSUs is capped at 200% of target, inclusive of the new relative TSR modifier. ▪ We believe that our current compensation program provides competitive pay, but we recognize that special equity awards can be a meaningful tool to attract and retain key employees. We enhanced our disclosure about the special equity award made in 2023 to an NEO.
Annual Cash Incentives ▪ Numerous stockholders that we spoke with commented that they would like the MIP to include metrics that reflect the achievement of sustainability goals and progress toward our aspirations for creating a diverse, equitable and inclusive workplace for all our associates.	Annual Cash Incentives ▪ The Compensation & Human Capital Management Committee incorporated a new Growth & Impact modifier into the 2023 MIP that adjusts an executive officer’s payout percentage based on the Company’s achievement of reductions in water intensity across our operations and demonstrated progress toward our aspirations for a more diverse, equitable and inclusive workplace. The assessment of performance for the Growth & Impact modifier is made for all officers in the aggregate. The MIP payout is increased by 3%, 6%, or 10%, or reduced by 10% based on achievement of year-over-year progress in these areas as determined by the Compensation & Human Capital Management Committee. Although the modifier may result in an increase in the payout percentage otherwise achieved under the annual incentive plan, in no event will payouts exceed 200% of target.

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 important 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. We also design annual cash incentives such that they pay out at a level commensurate with the Company’s performance based on adjusted EPS compared to 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 provides motivation to executives without incentivizing inappropriate risk-taking to achieve payouts, as we believe that the Company’s prospects for growth are generally at least as favorable as the average of the S&P 500. As described above, TDC opportunity for our CEO was positioned 6% below market median. All our other NEOs were positioned in the market median range, other than Mr. Duijser whose compensation is above market median as described in more detail on page 53.

Roles & Responsibilities in the Compensation Process

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

As requested from time to time, FW Cook:

▪

provides the Compensation & Human Capital Management 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 & Human Capital Management Committee of market trends in executive and director compensation.

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

For our NEOs, the Compensation & Human Capital Management Committee reviewed and approved all elements of 2023 compensation, taking into consideration 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 & Human Capital Management Committee also took into consideration 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 & Human Capital Management 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 those subject to Section 16 of the Exchange Act and other officers of the Company. 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 size-adjusted median general industry data from third-party surveys in which we participate.

The peer group and benchmarking methodology is approved by the Compensation & Human Capital Management 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, 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: ▪ revenue ▪ 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 ▪ not highly cyclical

Following this review process in 2023, the Compensation & Human Capital Management Committee approved the following 21-company peer group for 2023.

Peer Group​	3M Co.	Dover Corp.	Illinois Tool Works Inc.
	Agilent Technologies, Inc.	Dow Inc.	Linde plc
	Air Products and Chemicals Inc.	DuPont de Nemours Inc.	PPG Industries Inc.

APPROACH TO 2023 COMPENSATION BENCHMARKING
For benchmarking 2023 base salary and target annual cash incentives, we used the average of size-adjusted median compensation data from the 2022 Aon Radford survey and 2022 Willis Towers Watson survey, as well as median compensation data from the peer group.	For benchmarking 2023 long-term incentives, we used the average of size-adjusted median compensation data from the 2023 Willis Towers Watson survey and the 2023 FW Cook survey, as well as median compensation data from the peer group.

PROGRAM ELEMENTS

The principal elements of our executive compensation programs for 2023 are illustrated below:

COMPENSATION COMPONENT			BASIC DESIGN	PURPOSE
FIXED	BASE SALARY		▪ Calibrated with the median range of the size-adjusted competitive market	▪ Designed to provide a base wage not subject to Company performance risk ▪ Recognizes individual experiences, skills, and sustained performance
AT RISK	ANNUAL CASH INCENTIVE		▪ Actual pay varies between 0% and 200% of target ▪ Uses adjusted EPS and, for Messrs. Brown and Duijser, uses enterprise goals, and for all NEOs other than CEO, individual goals ▪ Subject to Growth & Impact modifier, up to the annual cash incentive cap of 200%	▪ Incentivizes the accomplishment of annual corporate, business, and individual goals, and Impact aspirations ▪ EPS and enterprise goals reflect the performance of all of our businesses
	LONG-TERM EQUITY INCENTIVES	Stock Options	▪ Represents 40% of annual long-term incentive award opportunity ▪ Vests 1/3 per year starting on the 1st anniversary of grant date	▪ Aligns pay to performance by linking value to stock price appreciation and shareholder value creation; value of the award is driven by share price appreciation following the grant date
		PBRSUs	▪ Represents 60% of annual long-term incentive award opportunity ▪ Performance measured on 3-year average organic ROIC, subject to a relative TSR modifier ▪ Actual payout ranges from 0% to 200% of target	▪ Aligns a portion of equity compensation to a longer-term strategic financial goal coupled with a relative stock price performance measure
OTHER	CHANGE IN CONTROL SEVERANCE COMPENSATION POLICY		▪ Double trigger ▪ Severance is 2x the sum of base salary and target annual incentive, pro rata actual annual bonus in year of termination, outplacement, and continued medical and dental for up to 18 months	▪ Applies to all elected officers ▪ Promotes continuity, impartiality, and objectivity in the event of a change in control to enhance stockholder value

48      ECOLAB PROXY STATEMENT 2024

Executive Compensation

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, 89% of our CEO’s target TDC and 79% of the average target TDC (which excludes any special equity awards) of the remaining NEOs other than our CEO is performance-based. The higher 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.

Target compensation mix does not include any grants of special long-term equity incentives. For more information on our compensation philosophy and process, see page 46.

Base Salaries

With limited exceptions, such as promotions and executive transitions, the Compensation & Human Capital Management Committee reviews base salaries for our NEOs and other executives annually in February to be effective in April of the current fiscal year, and 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 a number of years to arrive at the median. Accordingly, the base salary for our CEO has gradually been increased to the market median range following his appointment as CEO effective January 1, 2021. The base salary levels were within the median range for all of our NEOs. Except as explained above for our CEO, whose increase reflects phased-in adjustments to bring his salary to market median, the merit increases for our other NEOs were in line with the principles and metrics used to deliver the Company’s U.S. salary increases broadly.

The 2023 annualized base salary rates in effect for our NEOs before and after increases are summarized below:

NAME	BEGINNING ANNUALIZED BASE SALARY RATE ($)		ANNUALIZED BASE SALARY RATE FOLLOWING 2023 ANNUAL ADJUSTMENT ($)		INCREASE PERCENTAGE
Christophe Beck	​	1,075,000	​	1,300,000	​	20.9%

Darrell R. Brown	​	750,000	​	800,000	​	6.7%
Machiel Duijser	​	585,000	​	625,000	​	6.8%

ECOLAB PROXY STATEMENT 2024      49

Executive Compensation

Annual Cash Incentives

The Company maintains an annual cash incentive program for executives referred to as the Management Incentive Plan, or MIP. The Compensation & Human Capital Management Committee establishes goals under the MIP at its February meeting. In February 2024, the Compensation & Human Capital Management Committee reviewed the performance of the NEOs and other executives to determine the 2023 MIP award payments earned in 2023 (which were paid in March 2024).

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. No changes were made to the 2023 target award opportunities for the NEOs, which are set forth below:

NAME	MIP TARGET AWARD (% OF BASE SALARY)		MIP TARGET AWARD ($)
Christophe Beck	​	150%	​	1,865,625
Scott D. Kirkland	​	100%	​	787,500
Darrell R. Brown	​	100%	​	787,500
Machiel Duijser	​	75%	​	461,250
Lanesha T. Minnix	​	85%	​	545,063

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.

▪

ADJUSTED EPS: As in prior years, the primary measure of overall corporate performance under the 2023 MIP was adjusted EPS (or “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 comparison of results. We also use adjusted EPS internally in making financial and operational decisions and evaluating our performance. In addition, a total company measure of performance such as adjusted EPS is used as one of the performance measures with respect to our NEOs who manage particular business units because it reinforces our Circle the Customer — Circle the Globe strategy and fosters cross-divisional cooperation.

▪

ENTERPRISE GOAL: For NEOs such as Messrs. Brown and Duijser, whose roles have a significant impact on the performance of all of the Company’s businesses, and a direct impact on the Company’s ability to meet business sales and operating income targets, the 2023 MIP also is based on an enterprise performance goal. This goal is intended to incentivize and reward the NEOs based on the financial performance of Ecolab’s various businesses and overall Ecolab performance. 60% is comprised of a commercial average payout, which represents the aggregate of the payouts for the achievement of business unit sales and/or operating income goals to all employees in the commercial organization over the aggregate of the business unit payouts at target. The remaining 40% of such bonuses are earned based on the Company-wide adjusted EPS, which reflects Ecolab’s overall business performance.

▪

INDIVIDUAL GOALS: We utilize strategic corporate initiatives and goals, as detailed beginning on page 52, which may include human capital and sustainability indicators such as safety and environment, as a part of the individual performance measures to promote sustained company success.

▪

GROWTH & IMPACT MODIFIER: New for 2023 and in response to stockholder feedback, the Compensation & Human Capital Management Committee added a Growth & Impact modifier to the 2023 MIP for officers. The modifier is based on reducing water intensity across our operations and demonstrating progress toward our aspirations for a more diverse, equitable and inclusive workplace. This modifier recognizes that delivering a net positive impact for our associates, in our operations and for our customers, drives performance and innovation, and enables fast growth. The Compensation & Human

50      ECOLAB PROXY STATEMENT 2024

Executive Compensation

Capital Management Committee determined to include this new goal in our annual incentive plan to measure annual progress and ensure continuous progress is made against these important objectives.

PERFORMANCE MEASURES AND ACHIEVEMENT — ADJUSTED EPS

In establishing the adjusted EPS goal for 2023, we took into consideration our prior year results, overall economic and market trends, other large companies’ performance expectations, and our anticipated business opportunities, investment requirements, and the competitive situation. The minimum adjusted EPS level was set at $4.40, slightly below our actual adjusted EPS of $4.49 for 2022; however, the target opportunity was set at a level requiring 4% growth and the maximum opportunity at a level requiring 14% growth. For 2023, the adjusted EPS goals were as follows:

PERCENTAGE OF THE TARGET AWARD OPPORTUNITY	ADJUSTED EPS ($)
40% (Minimum Level)	​	4.40
100% (Target Level)	​	4.67
140% (140% Level)	​	4.85
200% (Maximum Level)	​	≥5.12

Payouts for results between performance levels are interpolated on a straight-line basis. Actual 2023 adjusted EPS of $5.21 was above the maximum level resulting in 200% payout with respect to this performance goal.

For purposes of the adjusted EPS performance measure used in the MIP, a reconciliation of 2023 diluted EPS as reported to 2023 adjusted diluted EPS is summarized below:

2023 reported diluted EPS	$	4.79
Adjustments:	​	​
Special (gains) and charges, after tax	​	0.38
Discrete tax net (benefit) expense	​	0.04
Adjusted diluted EPS	$	5.21

Note: Per-share amounts do not necessarily sum due to rounding. Additional information regarding the composition of the adjustments identified in the table above is contained on pages 32 to 36 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

PERFORMANCE MEASURES AND ACHIEVEMENT — GROWTH & IMPACT MODIFIER

In assessing the achievement of the Growth & Impact modifier for 2023, we considered the necessary steps to achieve our 2030 aspirations for reducing water use intensity across our operations and supporting our diverse, equitable and inclusive workplace. This modifier recognizes that delivering a net positive impact for our associates, in our operations and for our customers, drives performance and innovation, and enables fast growth. The MIP payout is increased by 3%, 6%, or 10%, or reduced by 10%, based on achievement of year-over-year progress in these areas as determined by the Compensation & Human Capital Management Committee.

For 2023, the Compensation & Human Capital Management Committee determined that the Growth & Impact modifier should increase the MIP payout by 6% for NEOs, up to a cap of 200% payout under the MIP. This payout level is aligned to exceeding the target set for reduction in water intensity across our operations and the assessment that performance towards Ecolab’s aspirations for a diverse, equitable and inclusive workplace demonstrated year-over-year improvement in some, but not all areas. 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. The water impact target was adjusted by the Compensation & Human Capital Management Committee for the Purolite acquisition.

PERFORMANCE MEASURES AND ACHIEVEMENT — ENTERPRISE GOAL

30% of Mr. Brown’s and 35% of Mr. Duijser’s 2023 MIP annual cash incentive is based on the performance of our enterprise goal. Mr. Brown’s and Mr. Duijser’s roles have a significant impact on the performance of all of the Company’s businesses, and direct impact on the Company’s ability to meet business sales and operating income targets. The enterprise performance goal is intended to incentivize and reward these NEOs based on the financial performance of Ecolab’s various businesses and overall Company performance.

Performance of the Enterprise Goal is measured 60% on the commercial average payout which is calculated by dividing the sum of all annual cash incentives earned by all employees in the commercial organization by the total target annual cash incentives for such employees. The resulting average reflects the aggregate commercial performance based on the aggregate payouts for the achievement of business unit sales and/or operating income goals. 40% of the Enterprise Goal is measured

ECOLAB PROXY STATEMENT 2024      51

Executive Compensation

on Company-wide adjusted EPS, which reflects Ecolab’s overall business 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 134%, and EPS was achieved at 200%, resulting in an enterprise goal payout of 160%.

Payouts to employees outside of the United States were converted to US$ at fixed currency rates of foreign exchange. Business unit performance plan results may 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, and these adjustments are included in determining the average payouts of the business unit performance plans. 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 32 to 34 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

PERFORMANCE MEASURES AND ACHIEVEMENT — INDIVIDUAL

For three of our NEOs who hold staff positions — Mr. Kirkland (Chief Financial Officer), Mr. Duijser (Executive Vice President and Chief Supply Chain Officer), and Ms. Minnix (Executive Vice President, General Counsel and Secretary), 30% of their annual cash incentive is based upon attainment of 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 performance goals.

The 2023 individual performance objectives for these officers are:

▪

specific,

▪

qualitative,

▪

achievable with significant effort, and

▪

if achieved, provide meaningful benefit to the Company.

The CEO’s Growth & Impact modifier was paid at 0% because he achieved his maximum payout of 200%.

Although the Compensation & Human Capital Management Committee has ultimate authority to increase or decrease an NEO’s payout from the level recommended by applying the MIP performance metrics, with input from the CEO (other than as to his or her own award), based on the individual performance of the NEO, they have 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 2023 annual cash incentive payouts were made in accordance with the overall corporate results and enterprise or individual performance results established for the NEOs without adjustment.

Long-Term Equity Incentives

The Compensation & Human Capital Management Committee made annual grants of long-term equity incentives to our NEOs in December 2023, 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 2023, our NEOs received long-term incentives within the median range, other than Mr. Duijser whose long-term incentive grant was above market median, in consideration of his unique skill set and background, which includes experience with products similar to those sold by all of our businesses, as well as his success in implementing step changes in technology and efficiency within our supply chain organization. Generally, long-term equity incentives are granted on the same date as our Compensation & Human Capital Management Committee approval date and in no event is the grant date prior to the approval date. We do not have a program, plan, or practice to time long-term equity incentive grants to executives in coordination with the release of material non-public information. The table below sets forth each NEO’s annual long-term incentive award value at target, as well as the number of target PBRSUs and stock options granted in December 2023.

Executive Compensation

The material terms of the 2023 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 average annual organic ROIC goals ▪ Payout ranges from 0% to 200% of the target award, with a threshold payout of 40% of target ▪ Utilizes organic ROIC, instead of the adjusted ROIC used in previous years, to simplify and improve alignment of the ROIC calculation with the industry standard ▪ Set 2024 to 2026 average annual organic ROIC target of 13.4%, with a threshold of 10.0% and a maximum of 15.7%, which is challenging as compared to the actual three-year average annual organic ROIC of 11.2% for each of the 2020 — 2022 and 2021 — 2023 performance periods ▪ Organic ROIC is defined as the quotient of net operating profit after taxes, over the Company’s 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 made prior to the reporting 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 2021 TO 2023 PBRSUs

Each of our NEOs other than Ms. Minnix held outstanding 2021 to 2023 PBRSUs granted by the Compensation & Human Capital Management Committee in December 2020 which vested on December 31, 2023. 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 2021 to 2023 PBRSUs, which resulted in a payout at 100% of target.

Adjusted ROIC under the 2021 to 2023 PBRSUs is defined as the quotient of after-tax operating income divided by the sum of short-term and long-term debt and shareholders’ 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.

Executive Compensation

2023 SPECIAL EQUITY AWARDS

In addition to the annual equity grants, we may make special equity awards to our NEOs and other executives in connection with promotions and recruitment, and for general retention purposes. In February 2023, prior to our 2023 Annual Meeting of Stockholders, the Compensation & Human Capital Management Committee approved a grant to Mr. Duijser of 13,112 restricted stock units (‘‘RSUs’’) valued at approximately $2,000,000.

The RSUs cliff-vest after four years and were granted in recognition of Mr. Duijser’s:

▪

exceptional leadership in navigating the negative external impacts of inflation and post-Covid-19 supply chain complexity,

▪

unique skill set and background, which includes experience with products similar to those sold by all of our businesses, as well as success in implementing step changes in technology and efficiency within our supply chain organization, and

▪

for retention purposes given the exceptionally competitive market for talent in this function.

Executive Benefits and Perquisites

Our NEOs participate in all of 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”. Our perquisites account for 0.9% of total compensation for the CEO and 1.5% of total compensation on average for the other NEOs in 2023. Executive benefits and perquisites are consistent with our competitive market.

The Company has maintained a private aircraft use policy for several years authorizing the use of private aircraft for business and personal use 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 $100,000 of unreimbursed usage per year, with personal use historically falling far below the limit. Additional information with respect to this perquisite is provided in more detail in the footnotes to the “Summary Compensation Table”.

The Compensation & Human Capital Management Committee approved an annual commuter allowance of $50,000 for Mr. Brown, Mr. Duijser and Ms. Minnix that is designed to offset commuting expenses incurred by these executives for travel to headquarters. None of Mr. Brown, Mr. Duijser and Ms. Minnix receives 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.

ECOLAB PROXY STATEMENT 2024      55

Executive Compensation

Hedging Policy

The Company’s 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 significant ownership stake so they are incentivized to maximize long-term stockholder returns. 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 RSUs/PBRSUs are not considered owned for purposes of complying with the guidelines.

STOCK OWNERSHIP GUIDELINES

The table below illustrates the standing of each of our NEOs in relation to their respective stock ownership guidelines as of December 31, 2023, based on the closing market price of our Common Stock on December 29, 2023 of $198.35 per share.

Excludes shares underlying unexercised stock options and unvested RSUs/PBRSUs.

Clawback and Compensation Recovery Policies

The Company’s Board of Directors has adopted a Policy on Reimbursement of Incentive Payments, which was most recently amended in November 2023. 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 & Human Capital Management 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 & Human Capital Management Committee may recoup any excess incentive compensation.

Also in 2023, the Company’s Board of Directors 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

Executive Compensation

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 & Human Capital Management 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 & Human Capital Management Committee. The Committee maintains final authority for overseeing risk in our compensation programs.

Our risk assessment revealed that our compensation programs do not 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 & Human Capital Management 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 Company’s 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 award grants at target and, in the case of Mr. Duijser, an additional special RSU award valued at $1,972,963, made during the year in accordance with FASB ASC Topic 718, based on the average of the high and low share price of the Company’s common stock on the date of grant, adjusted for the absence of future dividends. See Note 11 to the Company’s Consolidated Financial Statements for the year ended December 31, 2023, located at Item 8 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 for further discussion of the assumptions used in determining these values. The PBRSU awards cliff-vest after three years, subject to attainment of 3-year average organic ROIC goals over the performance period, and include a 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. The special restricted stock unit award for Mr. Duijser vests as to 100% of the units on the fourth anniversary date of the grant. For additional information about these awards see the heading “Long-Term Equity Incentives” beginning at page 53 and the footnotes to the table “Grants of Plan-Based Awards for 2023” beginning at page 60. Based on the fair market value on the date of grant ($187.49 per share), the maximum values for the 2023 PBRSUs granted to Messrs. Beck, Kirkland, Brown and Duijser and Ms. Minnix are $11,749,248, $3,394,319, $3,524,812, $2,088,639, and $1,958,146, respectively.

(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, 2023, located at Item 8 of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, for further discussion of the assumptions used in determining these values. The specific assumptions used in the valuation of the options granted in 2023 are summarized in the table below:

GRANT DATE	RISK FREE RATE		EXPECTED LIFE (YEARS)		EXPECTED VOLATILITY		EXPECTED DIVIDEND YIELD
12/06/2023 (all executives)	​	4.10%	​	6.11	​	22.37%	​	1.19%

Executive Compensation

(4)

Represents the annual cash incentive awards earned and paid in respect of 2023 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 2023” at page 60.

(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, 2023 over such amount as of December 31, 2022, 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 64 as part of the table entitled “Pension Benefits for 2023.” 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 2023 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 2023. Mr. Brown’s change in pension benefit is accrued in Australian dollars and is reported based on a conversion rate of 1.5140AUD = 1$U.S. on November 30, 2023, and a conversion rate of 1.4736AUD = 1$U.S. on November 30, 2022, using pension measurement dates of November 30, 2023 and November 30, 2022, 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 67.

(6)

Except as otherwise noted, amounts reported as All Other Compensation include:

(a)

Payment by the Company of certain perquisites, including costs relating to the following:

(i)

executive physical examinations for Messrs. Kirkland, and Brown;

(ii)

the personal use of corporate aircraft by Mr. Beck, with incremental cost calculated using a method that takes into account aircraft fuel expenses and engine reserve expense per flight hour, as well as any landing and parking fees, crew travel expenses, on-board catering costs, and dead-head flight costs attributable to such use;

(iii)

in the case of Mr. Brown, the personal use of a company vehicle, as well as tax preparation fees related to his foreign citizenship and a gross up thereon of $1,193;

(iv)

in the case of Mr. Brown, Mr. Duijser and Ms. Minnix, $50,000 representing an annual commuter allowance to offset commuting expenses incurred for travel between their residences and corporate headquarters;

(viii)

business travel and accident insurance for each of the named executive officers for which no incremental cost is allocated to the named executive officers.

(b)

(c)

Payment of matching contributions made by the Company for 2023 as follows:

(ii)

matching contributions made or to be made by the Company on base salary and annual cash incentive award earned in respect of 2023 that the executive deferred under a non-qualified defined contribution deferred compensation plan maintained by the Company for a select group of executives, in the following amounts: Mr. Beck, $278,700; Mr. Kirkland, $27,450; Mr. Brown, $121,677; Mr. Duijser $71,513, and Ms. Minnix, $0.

The Company maintains a self-funded, supplemental long-term disability benefit plan for certain executives, which benefits each of the named executive officers. No specific allocation of cost is made to any named executive officer prior to the occurrence of a disability.

(7)

Mr. Duijser was not an NEO in 2022 and 2021 and Mr. Brown, Mr. Kirkland and Ms. Minnix were not NEOs in 2021.

(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), without achievement of the commercial average, assuming the Growth & Impact modifier is not achieved and the negative 10% modifier applies.

(2)

Threshold amount is calculated assuming the relative TSR modifier is not achieved and the negative 10% modifier applies.

(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 2023. 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. Payout is further subject to a relative TSR modifier which may increase or reduce the payout percentage based on our 3-year TSR compared to the S&P 500. Dividend equivalents are not paid or accrued during the performance period. See the discussion under the heading “Performance-Based Restricted Stock Units” 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 an RSU award to Mr. Duijser. The award will vest as to 100% of the units on the fourth anniversary of the date of grant. Dividend equivalents are not paid or accrued on unvested units.

(5)

If an option holder terminates employment at or after age 55 with five or more years of continuous employment, stock options held at least six months will become immediately exercisable in full and the service-based vesting conditions on PBRSU awards held at least six months will be deemed satisfied but vesting will remain subject to attainment of the performance goals; all unvested RSU awards will terminate and be forfeited. A discussion of the consequences of a change in control on outstanding options, PBRSU awards, and restricted stock awards begins at page 70 under the heading “Change in Control (Double Trigger).”

(6)

Options granted in 2023 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.

Executive Compensation

(7)

Each of the stock options granted to our NEOs during the year ended December 31, 2023 and reported in the table above were granted on the same date as our Compensation & Human Capital Management Committee approval date 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 potential same-day stock volatility.

(8)

Represents the grant date fair value of each equity award, computed in accordance with FASB ASC Topic 718. With respect to stock options, the value has been determined by application of the lattice (binomial)-pricing model, based upon the terms of the option grant and Ecolab’s stock price performance history as of the date of the grant. Key assumptions include:

▪

risk-free rate of return,

▪

expected life of the option,

▪

expected stock price volatility, and

▪

expected dividend yield.

The specific assumptions used in the valuation of these options are located in footnote (3) to the “Summary Compensation Table” at page 58. With respect to PBRSUs, the value has been determined based on the average daily share price of the Company’s Common Stock at the date of the grant, adjusted for the absence of future dividends, and assuming the target award payout, consistent with the estimate of aggregate compensation cost to be recognized over the three-year vesting period of the award. See footnote (3) above for a description of the performance goals and performance period. With respect to RSUs, the value has been determined based on the average daily share price of the Company’s Common Stock at the date of the grant, adjusted for the absence of future dividends.

(9)

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,” including detail regarding the MIP performance Growth & Impact modifier. In the case of the NEO participants, the potential payouts that could be earned under the MIP for 2023 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 2023. Actual payouts to each of the NEOs with respect to 2023 are included under the Non-Equity Incentive Plan Compensation column in the “Summary Compensation Table” at page 58. 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, 2023 (November 30, 2023, 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 4.96% for the Pension Plan and 4.79% for the Mirror Pension Plan and SERP for 2023 and assuming that benefits are vested at December 31, 2023. The present value of Mr. Brown’s current accrued benefit in the Australia Plan was determined based on a 5.77% discount rate and based on a conversion rate of 1.5140AUD = 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, 2023.

▪

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. Mirror Pension and SERP annuities were valued assuming annual installment payments, or lump sums where available, using an interest rate of 6.00% 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 3.89% for periods after December 31, 2023. 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.

Mr. Beck has past service credits valued in the above table at $282,198 for 5.10 years of past service credit.

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, 2023, PBRSU and RSU awards are valued based on the value of a share of the Company’s stock of $198.35, which is the closing price on December 29, 2023, the last business day of the Company’s fiscal year, and option awards are valued based on the difference between $198.35 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 hereafter 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. Two of our NEOs, Mr. Beck, and Mr. Brown, would have been entitled to some or all of such special retirement provisions as of December 31, 2023, as follows:

If termination is after age 55 and completion of at least three 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” at page 58.

(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 the 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. The closing stock price on December 29, 2023, the last business day of the Company’s fiscal year, of $198.35, 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, 20,083 options, and Mr. Brown, 4,686 options.

(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 full attainment of performance goals, payment after the end of the performance period, and a stock price of $198.35.

Discharge for Cause

The Company is not obligated to pay any amounts in addition to the NEO’s vested benefits in the event of a termination of employment for cause as defined under the Company’s stock incentive plans. Certain elected corporate officers, including Mr. Beck, with qualifying age and years of service would receive coverage under the retiree life insurance program described in the above section entitled “Voluntary Resignation.”

Death or Disability

In the event of a termination as a result of death or disability, the NEO or his or her beneficiaries would be entitled to the following benefits in addition to his or her vested benefits:

(1)

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” at page 58.

(4)

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 29, 2023, the last business day of the Company’s fiscal year, of $198.35, 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, 20,083 options, Mr. Brown, 4,686 options, and Mr. Duijser, 4,017 options, Mr. Kirkland, 5,858 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 full attainment of performance goals, payment after the end of the performance period, and a stock price of $198.35.

(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, Brown, and Kirkland, and PBRSUs and RSUs for Ms. Minnix (10,558 PBRSUs/​$2,094,179 and 5,382 RSUs/$1,067,520), and Mr. Duijser (14,319 PBRSUs/$2,840,174 and 13,112 RSUs/$2,600,765).

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.

In addition, the Compensation & Human Capital Management Committee may, at its discretion, accelerate the vesting of PBRSU and RSU awards. The PBRSU awards further provide that vesting of the service-based vesting conditions will be

ECOLAB PROXY STATEMENT 2024      69

Executive Compensation

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.

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, two of our NEOs, Mr. Beck and Mr. Brown, would have been entitled to such special retirement provisions as of December 31, 2023.

(1)

For purposes of this disclosure, we have assumed that the negotiated settlement includes payment of up to two years’ base salary and target annual cash incentive for each of the NEOs listed.

(2)

At the discretion of the Compensation & Human Capital Management Committee, the vesting of options may be accelerated or extended and the exercise period extended. For purposes of this disclosure, we have assumed that the negotiated settlement does not provide for accelerated vesting of stock options.

(3)

In addition, the Compensation & Human Capital Management Committee may, at its discretion, accelerate the vesting of PBRSU and RSU awards. The PBRSU awards further 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. For purposes of this disclosure, we have assumed that the negotiated settlement does not provide for any additional acceleration of vesting, other than the pro-rated vesting provided in the PBRSU awards.

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 & Human Capital Management 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).

The peer group reflected for 2023 is the S&P 500 Materials Index and the peer group reflected for 2020-2022 is our compensation peer group from those years. In an effort to provide a more general comparison to companies in our sector and minimize year-over-year variability in the peer group, we have transitioned from use of our compensation peer group to the S&P 500 Materials Index for purposes of our peer TSR calculations. The table below provides a comparison of the Company’s cumulative total return with that of both the S&P 500 Materials Index and the previous peer group.

The dollar amounts reported represent the amount of net income reflected in the Company’s audited financial statements for the applicable year. The amount of net income for 2020 reflects a loss from discontinued operations, net of tax, of $2,172.5 million.

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.

PAY RATIO DISCLOSURE

For the year ended December 31, 2023, the annual total compensation for our CEO was $15,547,055, as reported in the final column of the “Summary Compensation Table” at page 58, and the annual total compensation for our global median employee was $49,177, calculated in accordance with the rules applicable to the “Summary Compensation Table”. For the year ended December 31, 2023, the annual total compensation for our CEO was 316 times the annual total compensation for our global median employee.

For purposes of identifying our global median employee in 2023, 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:

COUNTRY	NUMBER OF EMPLOYEES
Lebanon	​	1
Suriname	​	1
Antigua and Barbuda	​	2
Jordan	​	2
Tunisia	​	4
Guam	​	7
Tanzania	​	19

COUNTRY	NUMBER OF EMPLOYEES
Uganda	​	23
El Salvador	​	26
Nicaragua	​	28
Ukraine	​	35
Honduras	​	40
Pakistan	​	74

COUNTRY	NUMBER OF EMPLOYEES
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 and then calculated their total annual compensation.

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, 2024.

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, 2024, 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, 2024, 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 2023, the aggregate fees and expenses of which are reported at page 81.

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, 2024. 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 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 Mses. McKibben and Reich and Messrs. MacLennan and Nowell 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 25 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, 2023, 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, 2023, for filing with the SEC.

Stockholder Proposal​

PROPOSAL 4 — STOCKHOLDER PROPOSAL REGARDING AN INDEPENDENT BOARD CHAIR POLICY​ The Board of Directors unanimously recommends that you 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 in order that 2 separate people hold the office of the Chairman and the office of the CEO as follows:

Whenever possible, the Chairman of the Board shall be an Independent Director.

The Board has the discretion to select a Temporary Chairman of the Board who is not an Independent Director to serve while the Board is seeking an Independent Chairman of the Board on an accelerated basis

This policy could be phased in when there is a leadership transition.

This proposal topic won 52% support at Boeing and 54% support at Baxter International. Boeing then adopted this proposal topic in June 2020. The roles of Chairman and CEO are fundamentally different and should be held by 2 directors, a CEO and a Chairman who is completely independent of the CEO and our company. This proposal won 45% shareholder support at the 2023 Ecolab annual meeting. This laws more than double the support it received previously.

Meanwhile executive pay was rejected by 32% of the vote when a 5% rejection is often the norm at well performing companies. And Mr. John Zillmer, chair of the executive pay committee was rejected by 38% of the vote. The 45% support for this proposal in 2023 and the 32% rejection of executive pay were all the more noteworthy since the Board of Directors made a special appeal to shareholders to oppose this proposal and to approve executive pay.

According to the 2023 Ecolab proxy Jeffrey Ettinger, the Ecolab Lead Director, does not originate any information, schedules or agendas that are forwarded to other Ecolab directors. A lead director is thus no substitute for an independent board chairman. With the current CEO serving as Chair this means giving up a substantial check and balance safeguard that can only occur with an independent Board Chairman. A lead director cannot call a special shareholder meeting.

A lead director can delegate many details of his lead director duties to others and then simply rubber-stamp it. The Board of Directors has not explained how shareholders can be sure of what goes on in regard to lead director delegation. The Board of Directors failed to publish any comparison of the duties of an Ecolab Chairman compared to the duties of a lead director.

82      ECOLAB PROXY STATEMENT 2024

Stockholder Proposal

One of the primary functions of an independent chairman of the Board is to manage the Board of Directors which is lacking at Ecolab since director John Zillmer, with 18 years on the ECL Board, was rejected by a 38% vote

The increased complexities of companies of more than $45 Billion in market capitalization, like Ecolab, demand that 2 persons fill the 2 most important jobs in the company.

Please vote yes:

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. Further, our Corporate Governance Principles provide that, as a guideline, the Lead Director role should rotate every four to six years to continuously bring new independent perspectives to that role.

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.

▪

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. In accordance with our Corporate Governance Principles, the independent directors appointed David MacLennan as Lead Director in 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 and Governance Committees is comprised solely of, and chaired by, independent directors. Additionally, each of the Finance and 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.

ECOLAB PROXY STATEMENT 2024      83

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 individual 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 selects all independent directors, committee chairs and committee members, and the Chairman does not actively participate in these selections.

▪

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.

In recent years, the roles of Chairman and CEO were combined, and then split when Mr. Beck was first appointed CEO. 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:

▪

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 17 years at Ecolab where he held leadership roles within the Industrial, 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.

84      ECOLAB PROXY STATEMENT 2024

Stockholder Proposal

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 23, 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 and 2023. Our stockholders rejected each of these proposals. In 2023, we reached out to stockholders representing over 50% of our outstanding shares and many of our top stockholders supported the Board’s decision to maintain flexibility concerning the structure of the Board, given the Board’s strong lead director role and independence.

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.

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.
