PROXY STATEMENT
​

​ | INFORMATION ABOUT THE ANNUAL MEETING | ​

Our 2024 Annual Meeting of Stockholders will be held on Wednesday, May 22, 2024 at 9:00 a.m., local time, at our principal executive offices located at 815 Chestnut Street, North Andover, Massachusetts 01845.

​ | Information About this Proxy Statement | ​

You have received this proxy statement because the Board of Directors of Watts Water Technologies, Inc. (which we also refer to as Watts or the Company) is soliciting your proxy to vote your shares at the 2024 Annual Meeting and at any continuation, adjournment or postponement of the 2024 Annual Meeting. This proxy statement includes information that we are required to provide to you under the rules of the Securities and Exchange Commission, or SEC, and is designed to assist you in voting your shares. Only stockholders of record at the close of business on March 27, 2024 are entitled to receive notice of and to vote at the Annual Meeting.
Beginning on or about April 8, 2024, we are mailing or making available to our stockholders of record as of March 27, 2024 a Notice of Internet Availability of Proxy Materials, or Internet Notice, containing instructions on how to access our proxy statement, proxy and annual report for the year ended December 31, 2023, as well as how to vote. Our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 is available in the Investors section of our website at https://investors.wattswater.com. If you are a stockholder and would like a copy of our Annual Report on Form 10-K or any of its exhibits sent to you, we will send it to you without charge. Please address all such requests to our Corporate Secretary at our principal executive offices.
Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be Held on May 22, 2024
This proxy statement and our 2023 annual report to security holders are available at https://materials.proxyvote.com/942749.

​ | Information About Voting | ​

Each share of our class A common stock, par value $0.10 per share, outstanding on the record date is entitled to one vote on each matter submitted, and each share of our class B common stock, par value $0.10 per share, outstanding on the record date is entitled to ten votes on each matter submitted. As of the close of business on March 27, 2024, there were outstanding and entitled to vote 27,419,704 shares of class A common stock and 5,958,290 shares of class B common stock.
Stockholders of Record
Stockholders of record may vote in person at the Annual Meeting or by proxy. There are three ways to vote by proxy:

TABLE OF CONTENTS​
•
By Internet—Stockholders of record may vote over the Internet by visiting the website listed on the Internet Notice and following the instructions;
​
•
By telephone—Stockholders of record located in the United States and Canada may vote by calling the toll-free telephone number listed at https://materials.proxyvote.com/942749 and following the instructions; or
​
•
By mail—Stockholders of record who request printed copies of our proxy materials may also vote by mail by signing and dating the proxy card and returning it in accordance with the instructions on the card.
​
If a choice is specified in a proxy, shares represented by that proxy will be voted in accordance with such choice. If no choice is specified, the proxy will be voted “FOR” the election of each of the nine nominees for director named in this proxy statement, “FOR” our named executive officer compensation, and “FOR” the ratification of the appointment of KPMG LLP.
You may revoke or change your proxy at any time before it is exercised by (i) delivering to us a signed proxy card with a date later than that of your previously delivered proxy, (ii) voting in person at the Annual Meeting, (iii) granting a subsequent proxy through the Internet or by telephone, or (iv) sending a written revocation to our Corporate Secretary at our principal executive offices. Attending the Annual Meeting will not revoke your proxy unless you specifically request that your proxy be revoked by sending a written revocation to our Corporate Secretary before the proxy is exercised or you vote in person at the Annual Meeting.
Beneficial Owners
If you are a beneficial owner and your shares are held in “street name” by a bank, broker or other holder of record, you will receive instructions from the holder of record as to how to vote your shares. You will need to follow the instructions of the holder of record in order to vote your shares. Many banks and brokers offer the option of voting over the Internet or by telephone, instructions for which would be provided by your bank or broker on a voting instruction form. If your shares are not registered in your own name and you plan to vote your shares in person at the Annual Meeting, you must contact your broker or agent to obtain a legal proxy or broker’s proxy card and bring it to the Annual Meeting in order to vote.

​ | Quorum; Required Votes; Abstentions and Broker Non-Votes | ​

The presence, in person or by proxy, of a majority of the voting power of the outstanding shares of class A common stock and class B common stock entitled to be cast at the Annual Meeting is necessary to constitute a quorum for the transaction of business. Abstentions and broker non-votes will be counted for purposes of determining whether a quorum is present for the transaction of business at the Annual Meeting. A “broker non-vote” occurs when a bank, broker or other nominee holder has not received voting instructions with respect to a particular matter and the nominee holder does not have discretionary authority to vote on that matter. A nominee holder has discretionary authority under the rules of the New York Stock Exchange, or NYSE, to vote street name shares on the ratification of the appointment of KPMG LLP as our independent registered public accounting firm, even if the nominee holder does not receive voting instructions from the beneficial owners, but will not have discretionary authority to vote on the election of directors, the approval of our named executive officer compensation, or any other proposals submitted for approval at the Annual Meeting.

TABLE OF CONTENTS​​
Proposal 1: Election of Directors
Under our by-laws, directors are elected by plurality vote. This means that the nine director nominees receiving the highest number of affirmative votes will be elected as directors. You may vote for all the director nominees, withhold your vote from all the director nominees or withhold your vote from any one or more of the director nominees. Votes that are withheld and broker non-votes will have no effect on the results of the vote.
Proposal 2: Advisory Vote on the Compensation of Our Named Executive Officers
Under our by-laws, the affirmative vote of the holders of a majority of the votes present or represented at the Annual Meeting and entitled to be cast will be required for approval on a non-binding, advisory basis, of the compensation of our named executive officers. If you submit a proxy or attend the meeting but choose to abstain from voting on this proposal, you will be considered present at the meeting and entitled to vote on such proposal. As a result, an abstention will have the same effect as if you had voted against such proposal. Broker non-votes, however, will have no effect on the proposal because they will not be considered to have been entitled to vote on such proposal.
Proposal 3: Ratification of Our Independent Registered Public Accounting Firm
Under our by-laws, the affirmative vote of the holders of a majority of the votes present or represented at the Annual Meeting and entitled to be cast will be required for approval of the ratification of the appointment of KPMG LLP as our independent registered public accounting firm. If you submit a proxy or attend the meeting but choose to abstain from voting on this proposal, you will be considered present at the meeting and entitled to vote on such proposal. As a result, an abstention will have the same effect as if you had voted against such proposal. Because brokers have discretionary authority under NYSE rules to vote street name shares on Proposal 3, we do not expect any broker non-votes in connection with this proposal.
Solicitation of Proxies
We will bear the expenses of preparing, printing and assembling the materials used in the solicitation of proxies. In addition to the solicitation of proxies by use of the mail or the Internet, we may also use the services of some of our officers and employees (who will receive no compensation for such services in addition to their regular salaries) to solicit proxies personally and by telephone and email. Brokerage houses, nominees, fiduciaries and other custodians will be requested to forward solicitation materials to the beneficial owners of shares held of record by them, and we will reimburse them for their reasonable expenses.
We intend to file a proxy statement and WHITE proxy card with the SEC in connection with our solicitation of proxies for our 2025 Annual Meeting. Stockholders may obtain our proxy statement (and any amendments and supplements thereto) and other documents as and when filed with the SEC without charge from the SEC’s website at: www.sec.gov.
Other Business to be Considered
Our management does not know of any business other than the matters set forth in the Notice of Annual Meeting of Stockholders and described above that will be presented for consideration at the Annual Meeting. If any other business should properly come before the Annual Meeting, the proxies will be voted in accordance with the direction of the proxy holders. Each of the persons appointed by the enclosed form of proxy present and acting at the meeting, in person or by substitute, may exercise all the powers and authority of the proxies in accordance with their judgment.

​ | PROPOSAL 1 ELECTION OF DIRECTORS | ​

Our entire Board is elected annually at each Annual Meeting. Our Board has nominated each of the nine individuals named below for election as a director at our 2024 Annual Meeting. If elected, each nominee will serve until our 2025 Annual Meeting and until such director’s successor has been duly elected and qualified. Proxies will be voted for each of the nominees named below unless otherwise specified in the proxy. Although we currently have 11 directors, current Board members Christopher L. Conway and W. Craig Kissel were not nominated for reelection at the 2024 Annual Meeting. We are therefore reducing the size of our Board effective upon the conclusion of the Annual Meeting and stockholders will only be able to cast votes for nine nominees at the Annual Meeting. All the nominees are currently members of our Board and were elected by our stockholders at the 2023 Annual Meeting, except for Rebecca J. Boll, who was elected to our Board on February 7, 2024, and Kenneth Napolitano, who was elected to our Board on March 12, 2024. Ms. Boll and Mr. Napolitano were identified as candidates to serve on our Board by a third-party search firm. We expect that all the nominees will be available for election, but if any of the nominees is unable to serve or for good cause will not serve at the time of the 2024 Annual Meeting, proxies solicited hereby may be voted for a substitute nominee designated by our Board or our Board may choose to reduce the number of directors serving on the Board.
Our Board of Directors recommends that stockholders vote “FOR” the election of each nominee as a director of Watts Water Technologies, Inc.
Information as to Nominees for Director
Set forth below are the names of the nominees for our Board of Directors, their ages, principal occupations for at least the past five years, the years they originally became members of our Board of Directors and certain other information. The ages of all nominees listed below are current as of May 22, 2024, the date of our 2024 Annual Meeting. All other information provided below for nominees other than Mr. Napolitano is current as of February 1, 2024, and all other information provided below for Mr. Napolitano is current as of March 12, 2024.

Our current compensation arrangements for non-employee directors were set effective as of the second quarter of 2022, informed by a comprehensive competitive analysis of non-employee director compensation performed for the Compensation Committee by its independent compensation consultant, Pearl Meyer & Partners, LLC. This review included a consideration of non-employee director

compensation practices among a peer group of companies identical to the peer group roster we used at the time for benchmarking executive pay practices, and the current compensation arrangements are intended to position our non-employee director compensation program at approximately the median of our peer group. Set forth below is a summary of the current compensation arrangements for our non-employee directors.

​ | Annual cash retainer: | ​ | ​ | ​ | $ | 85,000 | ​ | ​
​ | Additional annual cash retainer for the Lead Independent Director: | ​ | ​ | ​ | $ | 25,000 | ​ | ​
​ | Additional annual cash retainer for the Chairperson of the Audit Committee: | ​ | ​ | ​ | $ | 20,000 | ​ | ​
​ | Additional annual cash retainer for the Chairperson of the Compensation Committee: | ​ | ​ | ​ | $ | 15,000 | ​ | ​
​ | Additional annual cash retainer for the Chairperson of the Governance and Sustainability Committee: | ​ | ​ | ​ | $ | 12,500 | ​ | ​
​ | Value of annual grant of class A common stock: | ​ | ​ | ​ | $ | 130,000 | ​ | ​

We also reimburse non-employee directors for reasonable out-of-pocket expenses incurred in connection with attending Board and committee meetings. Non-employee directors do not receive any additional compensation for attendance at Board or committee meetings.
Our Board typically approves grants of stock awards to non-employee directors at its first quarterly meeting following the election of directors at our Annual Meeting of Stockholders. On July 31, 2023, we granted 713 shares of class A common stock to each of Messrs. Conway, Dubose, Dunbar, Kissel, Noonan and Reitmeier and Mses. Goeser and Raines. Such awards were not subject to vesting or any other conditions or restrictions. Under our Third Amended and Restated 2004 Stock Incentive Plan (the “2004 Stock Incentive Plan”), the maximum aggregate number of shares of class A common stock with respect to one or more awards that may be granted to a non-employee director during any one calendar year is 100,000. For the July 31, 2023 grants, our Board determined the number of shares to be awarded to our non-employee directors using a thirty-day trailing average stock price, which resulted in a grant date fair value that was slightly higher than the target value of the annual stock grant to non-employee directors.
We have instituted a program under which our non-employee directors may defer receipt of their annual grant of shares of class A common stock. If any dividends are paid on our class A common stock during the period in which the stock is deferred, the non-employee director accrues dividends in the amount he or she would have received if the shares had been issued and held by the director at the time the dividend was paid. The accrued dividends will be distributed, without interest, in cash at the end of the deferral period chosen by such director when the stock is issued to the director. Mr. Conway and Ms. Raines elected to defer receipt of their 2023 stock awards.
Our non-employee directors are subject to stock ownership guidelines. These guidelines stipulate that each non-employee director should own shares of our class A common stock with a market value of at least three times the amount of the annual cash retainer payable to non-employee directors, which market value was $255,000 for 2023. It is expected that this ownership level will generally be achieved within a three-year period beginning when a director is first elected to the Board. For purposes of determining a director’s compliance with these ownership guidelines, any deferred shares are considered held by the director. The Compensation Committee reviews each non-employee director’s compliance with these guidelines on an annual basis. Compliance is typically measured based on stock ownership as of the last day of the second fiscal quarter. At the end of the second fiscal quarter of 2023, all our non-employee directors who had been members of our Board for three or more years were in compliance with our stock ownership guidelines.
The following table contains information on compensation for the non-employee members of our Board of Directors during the fiscal year ended December 31, 2023.

​ | CORPORATE GOVERNANCE | ​

Our Commitment to Good Corporate Governance
We believe that good corporate governance and an environment of the highest ethical standards are important for us to achieve business success and to create value for our stockholders. Our Board is committed to high governance standards and continually works to improve them. We periodically review our corporate governance policies and practices and compare them to those suggested by various authorities on corporate governance and employed by other public companies. We also review guidance and interpretations provided from time to time by the SEC and the NYSE and consider changes to our corporate governance policies and practices in light of such guidance and interpretations.
Role of Our Board of Directors
Our Board monitors overall corporate performance and the integrity of our financial controls and legal compliance procedures. It appoints executive officers and oversees succession planning and our executive officers’ performance and compensation. Our Board oversees the development of fundamental operating, financial and other corporate plans, strategies and objectives, and conducts a year-long process which culminates in Board review and approval each year of a business plan, a capital expenditures budget and other key financial and business objectives. Our Board also oversees our approach to sustainability and corporate social responsibility.
Members of our Board keep informed about our business through discussions with our Chief Executive Officer and other members of our senior management team, by reviewing materials provided to them on a regular basis and in preparation for Board and committee meetings and by participating in meetings of the Board and its committees. We regularly review key portions of our business with the Board, and we introduce our executives to the Board so that the Board can become familiar with our key employees. In addition, we hold periodic strategy sessions between members of senior management and the Board, during which members of the senior management team provide in-depth reviews of various aspects of our business operations and discuss our strategy with respect to such operations.
10

TABLE OF CONTENTS
In 2023, our Board met eleven times and each incumbent director who was a member of our Board during 2023 attended at least 75% of the total number of meetings of the Board and all committees of the Board on which the director served.
The Role of Our Board in Risk Oversight
The Board’s role in our risk oversight process includes receiving regular reports from members of senior management on areas of material risk to us, including operational, financial, legal, regulatory, climate change, cybersecurity, sustainability, strategic and reputational risks, and geopolitical risks. The full Board (or the appropriate committee in the case of risks that are under the purview of a particular committee) receives these reports from senior management to enable it to understand our risk identification and assessment, risk management and risk mitigation processes and strategies. When a committee receives a report on a particular risk, the chairperson of the relevant committee reports on the committee’s discussion of such risk to the Board during a future Board meeting. This enables the Board and its committees to coordinate the risk oversight role. As part of its charter, the Audit Committee discusses the guidelines and policies that govern the process by which our exposure to risk is assessed and managed by management. The Board does not believe that its role in the oversight of our risks affects the Board’s leadership structure.
Oversight of Cybersecurity
Our Board recognizes the critical nature of cybersecurity to preserve the trust and confidence of our customers, suppliers, employees and stockholders. As part of its independent oversight of key risks facing the Company, the Board and Audit Committee receive regular updates from management on our approach to cybersecurity and our cybersecurity risk management program. The Board and Audit Committee receive reports from management, including the Chief Information Officer (“CIO”) and the Vice President (“VP”) of Information Security, on the Company’s security programs, risk management and risk profile, and the status of programs to strengthen the Company’s cybersecurity posture.
To protect the confidentiality, integrity, and availability of our critical systems and information, the Company has a cybersecurity risk management program that is overseen by our CIO and VP of Information Security. The program is planned to protect and preserve the security, integrity and up-time of the Company’s information technology systems and connected products, and also to protect the confidentiality and integrity of information maintained by the Company. Our employees receive regular education regarding relevant cybersecurity practices and how to protect information and data against cyber threats.
Our Cyber Security Council, comprised of senior leaders from many different parts of our business, also reviews and assesses security risks from a business and technology perspective across all organizations within the Company. Throughout the year, the Council receives presentations and reports on business and product security, including updates on policies and practices, risk profile, and third-party assessments.
Management Succession Planning
Our Board believes that one of its primary responsibilities is to oversee the development and retention of executive talent and to ensure that an appropriate succession plan is in place for our Chief Executive Officer and other members of senior management. Each year, the Board meets with our Chief Human Resources Officer and Chief Executive Officer to conduct a comprehensive review of management succession planning and to address potential vacancies in senior leadership, including succession planning for our Chief Executive Officer. In addition, during its quarterly meetings, the Board typically focuses on a particular business unit and/or function and conducts a comprehensive review of that business unit or function, including management succession planning and potential leadership vacancies within such business unit or function.
Our Board has also adopted an emergency succession process framework in the event of a sudden or unanticipated absence of our Chief Executive Officer. Under this framework, the Board periodically assesses and updates a prioritized list of emergency interim chief executive officer candidates
11

TABLE OF CONTENTS
and the framework outlines other high-level planning, notification and other actions with respect to the temporary or permanent absence of our Chief Executive Officer.
Commitment to Sustainability
We have demonstrated our commitment to environmental sustainability by reducing our impact on the environment in multiple areas of our global business and by providing innovative products and solutions that enable our customers to reduce their impact on the environment. We are also focused on building a sustainable company by adhering to responsible business practices, prioritizing employee safety and by providing our employees with opportunities for personal and professional growth, including through programs and initiatives to promote diversity, equity and inclusion. We also strive to have a positive impact on the communities in which we live and work and other communities in need through community involvement, educational partnerships and charitable giving.

​ | Sustainability Leadership | ​ | ​ | The Governance and Sustainability Committee of our Board of Directors has primary responsibility for the oversight of our environmental, social and governance (“ESG”) efforts and strategy. The Governance and Sustainability Committee reviews the Company’s ESG performance and strategic plans four times a year at its regularly scheduled quarterly meetings and receives additional updates from the Company’s Chief Sustainability Officer as needed. At the management level, our General Counsel and Chief Sustainability Officer, who reports directly to our Chief Executive Officer, has general oversight responsibility for all sustainability matters. Our General Counsel and Chief Sustainability Officer also chairs our global management-level Sustainability Steering Committee, which is made up of senior company leaders and is responsible for formulating our sustainability strategy and overseeing the execution of our ESG initiatives. | ​
​ | Sustainability Strategy | ​ | ​ | We conducted a materiality assessment with the assistance of an external consultant. The results of that assessment are being used by the Sustainability Steering Committee to identify our key focus areas and from there to build a strategy to address the priority ESG topics identified by the assessment. | ​
​ | Environmental Stewardship | ​ | ​ | We have made substantial progress in reducing the environmental impact of our operations. Recent initiatives have resulted in a reduction in our global water consumption and our greenhouse gas emissions, including through the implementation of smart monitoring systems in many of our high water use facilities to promote early leak and surge detection and investments in various energy reduction projects. With respect to our product handprint, we provide an extensive portfolio of products, components and systems that conserve water, save energy, reduce water waste and preserve water quality and safety. In addition, our goal is to embed sustainability throughout the lifecycle of our products to create safe, efficient, long-lasting products made with high-recycling-value materials wherever feasible. | ​

​ | Social Responsibility | ​ | ​ | We are committed to creating both economic and social value and we strive to have a positive impact on our global community. During 2023, we supported those in need through donations of money and products to several non-profit charitable organizations and through the volunteer efforts of our employees. One example was our ongoing partnership with the Planet Water Foundation. During 2023, we worked with Planet Water to fund the construction of eight AquaTowers and AquaSan systems in Cambodia, Vietnam, the Philippines and Indonesia and one AquaBlock emergency water system in Turkey to assist people impacted by the Kahramanmaras earthquake, which in total provide clean, safe drinking water for up to 24,400 people. | ​
​ | Governance, Business Ethics & Compliance | ​ | ​ | We believe that good corporate governance and an environment of high ethical standards are important for us to achieve business success and to create value for our stockholders. Our Board is committed to high governance standards and continually works to improve them. We periodically review our corporate governance policies and practices and compare them to those suggested by various authorities on corporate governance and employed by other public companies and consider changes to our corporate governance policies and practices in light of such guidance and interpretations. We have adopted a Code of Business Conduct applicable to all officers, employees and Board members worldwide that serves as the foundation for our ethics and compliance program, and drives policy development, training initiatives, and reinforcement of our values throughout the global organization. | ​
​ | Human Capital | ​ | ​ | Employee safety is one of our highest priorities and we strive for zero hazards and zero injuries by educating and training employees on safety best practices through awareness campaigns and related safety initiatives. In 2023, we reduced both our total recordable incident rate and lost time incident rate to record low rates. We are also committed to promoting an inclusive and engaging workplace. Reflecting our commitment to diversity, equity and inclusion, we have conducted a global diversity, equity and inclusion employee survey, enhanced our talent recruitment processes with a new diverse slate hiring policy in the U.S. (based on which we strive to include individuals from different backgrounds in the candidate pool for new positions), engaged with historically Black colleges and universities to attract and recruit diverse professionals, deployed training and development programs on unconscious bias, inclusive leadership and communicating about culturally sensitive issues, and we have several employee resource groups, which are open to all employees. | ​
​ | Recognition | ​ | ​ | In 2023, we were recognized for the fifth year in a row as one of Newsweek’s Most Responsible Companies and also named by Newsweek as one of America’s Greenest Companies. We were also selected as one of America’s Climate Leaders by USA Today. | ​

Additionally, in this Proxy Statement and our Sustainability Report, we may provide information that is not necessarily material for SEC reporting purposes but that is informed by various ESG standards and frameworks (including standards for the measurement of underlying data), internal controls, and assumptions or third-party information that are still evolving and subject to change. For example, our disclosures based on any standards may change due to revisions in framework requirements, availability of information, changes in our business or applicable government policies, or other factors, some of which may be beyond our control.
Board Leadership Structure
The Board’s leadership structure is designed to promote Board effectiveness and appropriately allocate authority and responsibility between the Board and management. In February 2022, in contemplation of the retirement of Mr. Kissel from the Board in May 2024 in accordance with the Board member retirement age policy set forth in our Corporate Governance Guidelines, the Board conducted a review of its leadership structure. As part of its review, the Board took into consideration the current composition of the Board, the people currently in the roles of chairperson of the Board’s committees, the Company’s circumstances, including its financial performance, trends in corporate governance practices, and current policies and practices in place to provide independent Board oversight of management. Based on its consideration of these and other factors, our Board determined that combining the roles of Chairperson and Chief Executive Officer is the most effective leadership structure for the Board at this time, and the Board unanimously elected Robert J. Pagano, Jr. as Chairperson of the Board. The Board had for many years previously separated the Chairperson and Chief Executive Officer positions and may decide to separate them again in the future if it believes that doing so would be in the best interests of the Company and its stockholders.
In conjunction with electing Mr. Pagano as Chairperson of the Board, the Board established the role of Lead Independent Director. In 2023, the Board unanimously elected David Dunbar as Lead Independent Director. In electing Mr. Dunbar as Lead Independent Director, the independent Board members considered the skills and attributes required of the role, Mr. Dunbar’s background and experience, including his position as Chief Executive Officer of Standex International Corporation, and Mr. Dunbar’s strong interpersonal skills and demonstrated independent judgment. The Lead Independent Director’s responsibilities include, among other things, presiding at executive sessions of the independent or non-management Board members, acting as a liaison between the independent directors and the Chairperson and Chief Executive Officer, providing advice and guidance to the Chief Executive Officer, advising the Chief Executive Officer of the Board’s information needs, and helping to set the agenda items for Board meetings.
The Board believes the current leadership structure is appropriate because it provides the Company and the Board with strong leadership, appropriate independent oversight of management, continuity of experience that complements ongoing Board refreshment, and the ability to communicate the Company’s business and strategy to stockholders, customers, employees and the public in a single voice.
Performance of Our Board and Committees
Our Board considers it important to continually evaluate and improve its effectiveness and that of its committees. Our Board and each of its standing committees conduct annual self-evaluations. The Governance and Sustainability Committee oversees our Board’s self-evaluation process. The results of each committee’s annual self-evaluation are reported to the Board.
Business Ethics and Compliance
We have adopted a Code of Business Conduct applicable to all officers, employees and Board members worldwide. The Code of Business Conduct is posted in the “Investors” section of our website at https://investors.wattswater.com. In addition, we intend to post on our website all disclosures that
14

TABLE OF CONTENTS​
are required by law or the NYSE listing rules concerning any amendments to, or waivers from, any provision of our Code of Business Conduct within four business days of the date of such amendment or waiver.
Director Independence
As of February 29, 2024, members of the Horne family beneficially owned 5,938,290 shares of our class B common stock that are subject to The George B. Horne Voting Trust Agreement—1997. These shares represented 68.3% of our total outstanding voting power. As trustee of The George B. Horne Voting Trust Agreement—1997, Timothy P. Horne has sole power to vote all the shares subject to the trust and effectively exercises control over voting power for the election of our directors. As a result, we are a “controlled company” under NYSE rules. As a controlled company, under NYSE rules, we are not required to have a majority of independent directors or Compensation or Governance and Sustainability committees consisting solely of independent directors. However, we strive to achieve the highest standards of corporate governance, including with respect to director independence, despite our status as a controlled company. Accordingly, we have chosen not to take advantage of the controlled company exemption under NYSE rules and are committed to having a Board with at least a majority of independent directors.
Under our Corporate Governance Guidelines, we require that at least a majority of the members of our Board meet the independence requirements of the NYSE. Under NYSE rules, a director qualifies as “independent” if the Board affirmatively determines that the director has no material relationship with the company of which he or she serves as a director. The Board is required to consider broadly all relevant facts and circumstances in making an independence determination. Material relationships can include commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships. The Governance and Sustainability Committee annually evaluates the independence of each non-employee director nominee and makes recommendations to the Board. In making its recommendations, the Governance and Sustainability Committee applies NYSE rules to determine a director’s independence and evaluates any other business, legal, accounting or family relationships between all non-employee director nominees and us.
The Governance and Sustainability Committee and our Board reviewed all relationships between us and each non-employee director nominee to determine compliance with the NYSE independence rules and our Corporate Governance Guidelines, and to evaluate whether there are any other facts or circumstances that might impair the director’s independence. Based on the results of this review and the recommendations of the Governance and Sustainability Committee, the Board determined that nine of our 11 current directors (Messrs. Conway, Dubose, Dunbar, Kissel, Napolitano and Reitmeier and Mses. Boll, Goeser and Raines) are independent under NYSE rules and that the composition of our Board therefore complies with our Corporate Governance Guidelines. Mr. Noonan is not independent because he is the son-in-law of Timothy P. Horne, our controlling stockholder. Mr. Pagano was deemed not to be independent since he serves as our Chief Executive Officer.
Dual Class Stock Structure
In recent years, certain proxy advisors have been critical of members of our Board of Directors for maintaining a dual class stock structure. In light of this, we would like to provide some background on our views regarding our dual class share structure.
Our class B common stock entitles its holders to ten votes for each share and our class A common stock entitles its holders to one vote per share. The enhanced voting rights associated with our class B common stock were established in the Company’s Certificate of Incorporation prior to the Company’s initial public stock offering in 1986. Notably, since the enhanced voting rights of the class B stock are provided for in our Certificate of Incorporation, those voting rights may only be changed by an amendment to our Certificate of Incorporation approved by the holders of a majority of each of our class A common stock and class B common stock, voting as separate classes. As such, our Board of Directors does not have the power to amend the voting rights of the class B common stock without the approval of the holders of a majority of the class B common stock.
15

TABLE OF CONTENTS​​​​
We maintain an open disclosure policy regarding the dual class structure, enabling stockholders to be well informed of the structure prior to investing. Moreover, our Board takes its fiduciary responsibility of overseeing fair and effective governance for all stockholders seriously, as demonstrated by its majority of independent directors, non-reliance on controlled company exemptions under NYSE rules and the fact that no policies providing preferential economic treatment to class B stockholders have been implemented.
Finally, Watts stock has delivered exceptionally strong total stockholder returns (TSR). For example, we have significantly outperformed relevant benchmarks over a 3, 5, and 10-year horizon for periods ending December 31, 2023.
Horne Family Board Participation
As described above, as of February 29, 2024, Timothy P. Horne controlled 68.3% of the voting power of our stock. Mr. Horne served as a member of our Board of Directors until our 2010 Annual Meeting, when he retired from the Board in compliance with the age limitation for Board members contained in our Corporate Governance Guidelines. Since his retirement from the Board, Mr. Horne has served as a director emeritus and has selectively participated in certain Board discussions at the invitation of our Board. Pursuant to our by-laws, Mr. Horne was reappointed as a director emeritus by our Board of Directors in February 2024 to serve a one-year term beginning on the date of our 2024 Annual Meeting and ending on the date of our 2025 Annual Meeting. As a director emeritus, Mr. Horne may be invited by our Board to attend Board or committee meetings, but he does not have the right to vote and he is not considered to be a member of the Board for any purpose (including quorum). Mr. Horne has an agreement with us, which provides Mr. Horne with the use of an office at our corporate headquarters and administrative support. The agreement also provides that Mr. Horne will make himself reasonably available to provide services to us at the request of our management as long as he is physically able to do so. Mr. Horne’s obligation to provide services to us will cease upon a change in control of our Company.
In May 2013, Mr. Horne’s son-in-law, Joseph T. Noonan, was elected as a member of our Board. We believe that it is strategically important for a Horne family member to be actively engaged in the oversight of our Company, including by serving on our Board of Directors. Through Mr. Noonan’s participation on the Board, the Horne family’s long-term perspective is considered in all Board decisions. Having a Horne family member on the Board serves as an effective link between the Board and the controlling Horne family stockholders. Board service also provides the controlling Horne family stockholders with an active means by which to oversee their investment.
Corporate Governance Guidelines
Our Board has adopted Corporate Governance Guidelines that govern the structure and functioning of the Board and set out the Board’s policies on governance issues. The Corporate Governance Guidelines are posted in the “Investors” section of our website at https://investors.wattswater.com.
Executive Sessions
In accordance with our Corporate Governance Guidelines, our non-management directors meet in executive session at least quarterly. The Lead Independent Director or, in his absence, a director chosen by the non-management directors in attendance, presides at such meetings.
Communications with the Board
Our Board welcomes the submission of any comments or concerns from stockholders and any interested parties. Communications should be in writing and addressed to our Corporate Secretary at our principal executive offices and marked to the attention of the Board or any of its committees, the Lead Independent Director, individual directors or non-management or independent directors as a group. All relevant and appropriate correspondence will be forwarded to the intended recipient(s).

Annual Meeting Attendance
Directors are encouraged to attend our annual meetings of stockholders. Eight of our then-nine directors attended the 2023 Annual Meeting either in person or by telephone conference call.
Committees of the Board
Our Board currently has three standing committees: the Audit Committee, the Compensation Committee and the Governance and Sustainability Committee. Each committee is composed solely of directors determined by the Board to be independent under the applicable NYSE rules. The Board has adopted a written charter for each standing committee. You may find copies of the charters of the Audit Committee, the Compensation Committee and the Governance and Sustainability Committee in the “Investors” section of our website at https://investors.wattswater.com. The Board also appoints from time to time ad hoc committees to address specific matters.

​ | Audit Committee​ The Board has made a determination that each of the members of the Audit Committee satisfies the independence requirements of the NYSE relating to service on an audit committee as well as Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act. In addition, the Board has determined that each of Ms. Raines and Messrs. Dunbar and Reitmeier is an “audit committee financial expert,” as defined by SEC rules. Our Audit Committee assists the Board in, among other things, its oversight of: ➤ the integrity of our consolidated financial statements; ​ ➤ our compliance with legal and regulatory requirements; ​ ➤ the qualifications, independence and performance of our independent registered public accounting firm; ​ ➤ the performance of our internal audit function; and ​ ➤ the effectiveness of our internal control over financial reporting. ​ The Audit Committee’s responsibilities also include: ➤ the appointment and evaluation of our independent registered public accounting firm; ​ ➤ the review of management’s assessment and management of risk; ​ ➤ the review of management’s approach to cybersecurity and information security assessments and risk mitigation; ​ ➤ the review of the annual independent audit of our consolidated financial statements; ​ ➤ the review of our Code of Business Conduct; ​ ➤ the establishment and oversight of “whistle-blowing” procedures; and ​ ➤ the oversight of other compliance matters. ​ The Audit Committee holds one regularly scheduled meeting each quarter and schedules additional meetings as often as necessary in order to perform its duties and responsibilities. During 2023, the Audit Committee held five meetings. The Chairperson of the Audit Committee works with management to establish the agenda for each meeting. Audit Committee members receive and review materials in advance of each meeting. These materials include information that management or the Company’s independent registered public accounting firm believe will be helpful to the Audit Committee as well as materials that members of the Audit Committee request. | ​ | ​ | COMMITTEE MEMBERS Merilee Raines, Chairperson Rebecca J.

​ | Compensation Committee​ Our Compensation Committee is responsible for shaping the principles, strategies and compensation philosophy that guide the design and implementation of our employee compensation programs and arrangements. Its primary responsibilities are to: ➤ evaluate the performance of our Chief Executive Officer and, either as a committee or together with the independent members of our Board of Directors, determine the compensation of our Chief Executive Officer; ​ ➤ review and approve, or recommend to the Board, the compensation of our other executive officers; ​ ➤ approve annual performance bonus targets and objectives and the annual bonus amounts paid to our executive officers under our Executive Officer Incentive Bonus Plan; ​ ➤ administer our stock incentive plans and approve all stock awards granted to our executive officers under our 2004 Stock Incentive Plan and the participants in our Management Stock Purchase Plan; ​ ➤ review and submit recommendations to our Board of Directors on compensation for non-employee directors; and ​ ➤ review and discuss with management the Compensation Discussion and Analysis to be included in the proxy statement. ​ | ​ | ​ | COMMITTEE MEMBERS Christopher L. Conway, Chairperson Michael J. Dubose Louise K. Goeser W. Craig Kissel | ​

The Board has determined that each of the members of the Compensation Committee satisfies the independence requirements of the NYSE relating to service on a compensation committee and that each member of the Compensation Committee qualifies as a “non-employee director” as defined in Rule 16b-3 of the Exchange Act.
The Compensation Committee holds one regularly scheduled meeting each quarter and schedules additional meetings as often as necessary in order to perform its duties and responsibilities.

of the Compensation Committee request. The Compensation Committee may establish and delegate authority to one or more subcommittees consisting of one or more of its members when the Compensation Committee deems it appropriate to do so in order to carry out its responsibilities.
The Compensation Committee is authorized under its charter to retain consultants to assist it in the evaluation of executive compensation and to approve the fees and other retention terms for its consultants. The Compensation Committee has retained Pearl Meyer & Partners, LLC as a compensation consultant to review our compensation programs and provide advice to the Compensation Committee with respect to executive compensation. Pearl Meyer does not provide any other services to us. The Compensation Committee has assessed the independence of Pearl Meyer and whether its work raised any conflict of interest, taking into consideration the independence factors set forth in the NYSE listing standards and SEC rules. Based on that assessment, the Compensation Committee believes that Pearl Meyer is independent and that its work does not raise any conflicts of interest. As appropriate, the Compensation Committee also looks to our human resources department to support the Compensation Committee in its work and to provide necessary information. In addition, the Compensation Committee also considers the recommendations of our Chief Executive Officer when approving the compensation of our executive officers other than the Chief Executive Officer.
In May 2023, the Compensation Committee conducted a review and assessment of risk as it relates to our compensation policies and practices and determined that our compensation policies and practices do not encourage excessive or inappropriate risk taking and are not reasonably likely to have a material adverse effect on our business.
Director Candidates
The Governance and Sustainability Committee will consider for nomination to the Board candidates recommended by stockholders. Recommendations should be sent to our Corporate Secretary at our principal executive offices and marked to the attention of the Governance and Sustainability Committee. Recommendations must be in writing and must contain the information set forth in Section IV.C of the Governance and Sustainability Committee charter, which is available in the Investors section of our website at https://investors.wattswater.com, or on written request to our Corporate Secretary at our principal executive offices.
In addition to considering candidates suggested by stockholders, the Governance and Sustainability Committee may consider potential candidates suggested by current directors, Company officers, employees, third-party search firms and others. The Governance and Sustainability Committee screens all potential candidates in the same manner regardless of the source of the recommendation. The Governance and Sustainability Committee’s review is typically based on any written materials provided with respect to the potential candidate. The Governance and Sustainability Committee determines whether the candidate meets our minimum qualifications and possesses specific qualities and skills for directors and whether requesting additional information or an initial screening interview is appropriate.
Stockholders also have the right under our by-laws to directly nominate director candidates, without any action or recommendation on the part of the Governance and Sustainability Committee or the Board, by following the procedures described later in this proxy statement under “Stockholder Proposals.”
In 2023, the Board engaged a third-party search firm to conduct a search for director candidates. After an extensive screening and interviewing process, the Board appointed Ms. Boll to the Board in February 2024 and the Board appointed Mr. Napolitano to the Board in March 2024. Ms. Boll and Mr. Napolitano are standing for election by our stockholders as members of our Board of Directors for the first time at the 2024 Annual Meeting.
Criteria and Diversity
We believe that our Board should be composed of directors who, as a group, have the experience, qualifications, attributes and skills that are collectively required to make informed Board decisions and provide effective Board oversight. The composite skills of the Board members and the ability and
20

TABLE OF CONTENTS
willingness of individual Board members to complement each other and to rely on each other’s knowledge and expertise should produce informed Board members who are not afraid to disagree and who can intelligently assess management’s performance and evaluate our strategic direction. In considering whether to recommend any candidate for nomination to the Board, including candidates recommended by stockholders, the Governance and Sustainability Committee must be satisfied that the recommended nominee has, at a minimum:
•
the highest personal and professional integrity;
​
•
sound business and strategic judgment;
​
•
the ability to devote sufficient time and energy to the Board; and
​
•
the ability and will to challenge management while refraining from assuming management’s role.
​
In addition, the nominee must not serve on more than two public company boards in addition to our Board.
The following table identifies the primary experience, qualifications, attributes and skills possessed by our director nominees, which our Board believes are relevant to our business, industry or strategy. Our Board reviewed and evaluated these experiences, qualifications, attributes and skills in nominating nine of our current directors for reelection and each contributed to the conclusion that each of these directors should serve as a member of our Board. The table does not encompass all the experience, qualifications, attributes or skills of our directors, and the fact that a particular experience, qualification, attribute or skill is not listed does not mean that a director does not possess it. In addition, the absence of a particular experience, qualification, attribute or skill does not mean that the director in question is unable to contribute to the decision-making process in that area. The type and degree of experience, qualification, attribute and skill listed below may vary among members of the Board.

Our Board also understands the importance of diversity among members of the Board to our long-term success. Diversity encompasses a wide range of individual characteristics and experiences, including such things as gender, age, race, sexual orientation, national origin, religion, political affiliation, marital status, disability, and geographic background. The Governance and Sustainability Committee believes that the backgrounds and qualifications of the members of the Board, considered as a group, should provide an appropriate mix of experience, knowledge and abilities that will allow the Board to fulfill its responsibilities. Our Board has adopted the practice that the criteria for all Board member search processes include a requirement to identify and present to our Board a substantial number of qualified

Compensation Committee Interlocks and Insider Participation
During 2023, Christopher L. Conway, Michael J. Dubose, Louise K. Goeser and W. Craig Kissel served as members of the Compensation Committee of our Board of Directors. None of the directors who served as members of the Compensation Committee during 2023 is or has ever been an officer or employee of our Company.
None of our executive officers serves as a member of the board of directors or compensation committee of any entity that has one or more of its executive officers serving as a member of our Board of Directors or Compensation Committee.
Restrictions on Hedging, Pledging and Other Transactions
We prohibit all hedging transactions and short sales involving our securities by all employees, officers and directors under our Insider Trading Compliance Policy. We also prohibit all employees, officers and directors from purchasing our securities on margin or holding any of our securities in margin accounts. In addition, no employee, officer or director may pledge any of our securities as collateral for a loan. Finally, all employees, officers and directors are prohibited from engaging in transactions in puts, calls or other derivative securities involving our securities.
Policies and Procedures for Related Person Transactions
Our Board has adopted a written Related Person Transaction Policy, which requires the review of any transaction, arrangement or relationship in which we are a participant, the amount involved exceeds $120,000, and one of our executive officers, directors, director nominees or 5% stockholders (or their immediate family members), each of whom we refer to as a “related person,” has a direct or indirect material interest.
If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a “related person transaction,” the related person must report the proposed related person transaction to our General Counsel. The policy calls for the proposed related person transaction to be reviewed and, if deemed appropriate, approved by the Board’s Governance and Sustainability Committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, the committee will review, and, in its discretion, may ratify the related person transaction. The policy also permits the chairperson of the committee to review and, if deemed appropriate, approve proposed related person transactions that arise between committee meetings, subject to ratification by the committee at its next meeting. Any related person transactions that are ongoing in nature will be reviewed annually.
A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the Governance and Sustainability Committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, the committee will review and consider:
23

TABLE OF CONTENTS
•
the related person’s interest in the related person transaction, regardless of the amount of any profit or loss;
​
•
the approximate dollar value involved in the related person transaction;
​
•
whether the transaction was undertaken in the ordinary course of our business;
​
•
whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;
​
•
the purpose of, and the potential benefits to us of, the transaction; and
​
•
any other material information regarding the related person transaction or the related person.
​
The Governance and Sustainability Committee may approve or ratify the transaction only if it determines that, under all the circumstances, the transaction is in, or is not inconsistent with, our best interests and the interests of our stockholders. The Governance and Sustainability Committee may impose any conditions on the related person transaction that it deems appropriate.
In addition to the transactions that are excluded by the instructions to the SEC’s related person transaction disclosure rule, the Board has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:
•
interests arising solely from the related person’s position as an executive officer of another entity (whether or not the person is also a director of such entity), that is a participant in the transaction, where (a) the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity, (b) the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction, (c) the amount involved in the transaction equals less than the greater of $1 million or 2% of the annual consolidated gross revenues of the other entity that is a party to the transaction, and (d) the amount involved in the transaction equals less than 2% of the annual consolidated gross revenues of our Company; and
​
•
a transaction that is specifically contemplated by provisions of our charter or by-laws.
​
The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by the Compensation Committee in the manner specified in its charter.

TABLE OF CONTENTS​

​ | PRINCIPAL STOCKHOLDERS | ​

The following table sets forth information regarding the beneficial ownership of our class A and class B common stock by:
•
each person or entity known by us to own beneficially more than 5% of either class of our common stock;
​
•
each of our directors and director nominees;
​
•
each of the executive officers named in the Summary Compensation Table; and
​
•
all our current directors and executive officers as a group.
​
Unless otherwise indicated in the footnotes, the information in the following table is provided as of February 29, 2024. In accordance with SEC rules, we have included in the number of shares beneficially owned by each stockholder all shares over which such stockholder has sole or shared voting or investment power, and all shares that the stockholder has the right to acquire within 60 days after February 29, 2024 through the vesting of deferred stock awards, the settlement of restricted stock units or any other right. Unless otherwise indicated, each stockholder has sole voting and investment power with respect to shares beneficially owned by that stockholder. For purposes of determining the equity and voting percentages for each stockholder, any shares that such stockholder has the right to acquire within 60 days after February 29, 2024 are deemed to be outstanding, but are not deemed to be outstanding for the purpose of determining the beneficial ownership percentages for any other stockholder.

The number of shares and percentages were determined as of February 29, 2024 in accordance with Rule 13d-3 of the Exchange Act. At that date, a total of 33,346,689 shares were outstanding, of which 27,388,399 were shares of class A common stock and 5,958,290 were shares of class B common stock. Each share of class A common stock is entitled to one vote and each share of class B common stock is entitled to ten votes. Each share of class B common stock is convertible into one share of class A common stock at any time. A holder of shares of class B common stock is deemed to beneficially own the shares of class A common stock into which the class B shares are convertible. Shares of class A common stock are not convertible. The table’s voting percentage reflects the applicable beneficial owner’s one vote per share of class A common stock plus ten votes per share of class B common stock, if any, divided by the total number of possible votes.

Horne, for so long as he is serving as trustee of the 1997 Voting Trust, has the power to determine in his sole discretion whether or not proposed actions to be taken by the trustee of the 1997 Voting Trust shall be taken, including the trustee’s right to authorize the withdrawal of shares from the 1997 Voting Trust (for purposes of this footnote, the “Determination Power”). In the event that Timothy P. Horne ceases to serve as trustee of the 1997 Voting Trust, no trustee thereunder shall have the Determination Power except in accordance with a duly adopted amendment to the 1997 Voting Trust. Under the terms of the 1997 Voting Trust, in the event that Timothy P. Horne ceases to serve as trustee of the 1997 Voting Trust, then Joseph T. Noonan, Mr. Horne’s son-in-law and a director of the Company, and Walter J. Flowers, a partner in the law firm of Flowers and Manning, LLP (each, a “Successor Trustee” and collectively, the “Successor Trustees”), shall thereupon become co-trustees of the 1997 Voting Trust. If a Successor Trustee shall cease to serve as such for any reason, then a third person shall become a co-trustee with the remaining Successor Trustee, in accordance with the following line of succession: first, any individual designated as the Primary Designee, next, any individual designated as the Secondary Designee, and then, an individual appointed by the holders of a majority in interest of the voting trust certificates then outstanding. So long as there are two Successor Trustees, the concurrence of both shall be necessary and sufficient for the validity of any action taken by such trustees and if at any time there is one Successor Trustee, such Successor Trustee’s action shall be necessary and sufficient for the validity of any action taken by such trustee. The 1997 Voting Trust was extended effective as of August 12, 2020 by unanimous

Executive Summary
Company Performance

​ | ​ | Key Results for 2023 | ​ | ​
​ | ​ | • Sales of $2.06 billion, an increase of 4% over 2022 ​ • Operating Income of $351 million, an increase of 11% over 2022 ​ • Earnings Per Share of $7.82, an increase of 5% over 2022 ​ • Operating Margin of 17.1%, an increase of 120 basis points from 2022 ​ | ​ | ​
​ | ​ |  | ​ | ​

In 2023 we continued our commitment to focus on our customers, executed on our strategic initiatives, drove new product development, especially in smart and connected enabled products, and promoted sustainability across the spectrum of environmental, social and governance issues. Our 2023 performance set new record highs for the Company for sales and operating margin and significant increases in operating income and earnings per share over 2022 results. We continued to build for the future by investing an incremental $24 million in new product development efforts, information technology enhancements and growth initiatives. We also generated $311 million of net cash from operating activities in 2023 as compared to $224 million in 2022.
During 2023, we continued to execute on our strategic priorities and strengthen our business:
•
We completed three strategic acquisitions in 2023 and early 2024, including Enware Australia Pty Ltd, a leading supplier of specialty plumbing and safety equipment used in the Australian institutional and commercial end markets, Bradley Corporation, a trusted provider and manufacturer of commercial washroom and emergency safety products serving commercial and industrial end markets, and Josam Company, a leading provider and manufacturer of drainage and plumbing products, serving commercial, industrial, and multi-family end markets.
​
•
We continued to focus on sustainability by taking steps to reduce the negative impact our operations have on the environment while at the same time generating economic value by designing, manufacturing and selling products and solutions that enable our customers to reduce the negative impact they have on the environment. In 2023, we were recognized for the fifth year in a row as one of Newsweek’s Most Responsible Companies and we were also selected by Newsweek as one of America’s Greenest Companies. We were also named one of America’s Climate Leaders by USA Today.

TABLE OF CONTENTS
•
We continued to execute on our smart and connected strategy by investing in IoT (Internet of Things) architecture development, enhancing digital tools used by our customers, including our website, and investing in new smart and connected enabled product development projects. We exited the fourth quarter of 2023 with 25% of our revenue from smart and connected enabled products, in line with our goal set in 2018.
​
•
We continued our comprehensive approach to diversity, equity and inclusion by conducting awareness and education programs for our leaders and employees; monitoring engagement through employee survey feedback; creating awareness with our employees about diversity, equity and inclusion topics through our Company intranet, employee meetings, panel discussions, trainings and our public website; and improving our hiring and leadership development processes to increase diversity, equity and inclusion at all levels. We also encouraged the participation of diverse employees through employee resource groups, which are voluntary employee-led groups that provide a forum for employees to share common interests and experiences, gain professional development support, engage with our leadership teams, and drive initiatives to improve diversity, equity and inclusion.
​
•
We enhanced productivity through the continued deployment of our One Watts Performance System, including training our employees on lean principles and techniques and performing continual improvement events to reduce complexity, better serve our customers and simplify work.
​
•
We continued to enhance employee safety and in 2023 we reduced both our total recordable incident rate and lost time incident rate.
​
•
We continued to provide stockholder value by repurchasing approximately $16 million of our class A common stock and increasing our annual dividend return by 20%.
​
Alignment of Pay with Performance
A substantial portion of each executive’s compensation is performance-based or aligned with stockholder value creation over time in the form of equity grants. Set forth below for our Chief Executive Officer, and separately for the other named executive officers, are charts illustrating the percentage of total target compensation mix corresponding to base salaries, annual incentives and long-term incentives for 2023.

TABLE OF CONTENTS
*
Total direct compensation mix does not include perquisites or other executive benefits, including retirement and severance benefits, or the value of the discount attributable to the purchase price for restricted stock units under our Management Stock Purchase Plan. Fixed compensation consists of base salary and variable compensation consists of target annual incentive and long-term incentive value. Long-term incentive value consists of annual grants of performance stock unit awards and deferred stock awards based on their grant date fair value as reported in the 2023 Summary Compensation Table below. Short-term compensation consists of base salary and target annual incentive. Long-term compensation consists of long-term incentive value. Cash compensation consists of base salary and target annual incentive. Equity compensation consists of long-term incentive value.
​
Other Practices and Policies to Promote Effective Compensation Governance
Examples of practices and policies that the Compensation Committee has implemented to ensure effective governance of compensation plans include:
•
Our executives are subject to robust stock ownership guidelines.
​
•
Our executives are subject to a compensation recovery policy, or “claw back” policy, which provides for the mandatory recovery (subject to limited exceptions) from current and former officers of incentive-based compensation that was erroneously received during the three years preceding the date that the Company is required to prepare an accounting restatement.
​
•
The Compensation Committee has engaged an independent compensation consultant.
​
•
The Compensation Committee has conducted a review and assessment of risk as it relates to our compensation policies and practices.
​
•
Our Insider Trading Compliance Policy prohibits hedging and short sale transactions, and no employee or director may pledge Company securities as collateral.
​
•
None of our executive officers has an employment agreement with us.
​

TABLE OF CONTENTS​
•
We do not provide excise tax gross-ups under any of our change in control severance arrangements.
​
•
We hold an annual stockholder say-on-pay advisory vote.
​
Say on Pay and Say on Frequency
We submitted our executive compensation program to an advisory vote of our stockholders at our 2023 Annual Meeting, and it received the support of over 98% of the total votes present and entitled to vote at the meeting. Our Board of Directors viewed the results of the 2023 advisory vote as broad stockholder support for our executive compensation program and did not make any fundamental changes to our executive compensation program or policies as a result of the advisory vote. The Compensation Committee will, in consultation with its independent compensation consultant, consider changes to our compensation programs as appropriate in response to evolving factors such as the business environment and competition for talent. In considering changes to our compensation programs and policies, the Compensation Committee may seek additional input from stockholders with respect to our executive compensation policies and decisions.
At our 2023 Annual Meeting, our stockholders strongly supported a frequency of “every year” for holding future advisory votes to approve the compensation of our named executive officers, consistent with the recommendation of our Board. As a result, our Board decided to hold annual “Say on Pay” votes, and we are presenting a proposal to our stockholders to approve on an advisory basis the compensation of our named executive officers as disclosed in this proxy statement. See Proposal 2 of this proxy statement.
Compensation Philosophy
Our executive compensation philosophy, as adopted by the Compensation Committee of our Board of Directors, is to provide compensation programs that attract, retain and motivate our key executives who are critical to our long-term success. We implement this philosophy through the following principles:
•
Positioning total direct compensation and each component of compensation at approximately the median of our peer companies, which are industry and size relevant and which are identified by a rules-based selection process. Some variation in competitive positioning by executive is expected to account for factors such as relevant business experience, individual performance and criticality of role.
​
•
Rewarding achievement relative to short- and long-term goals that we believe will drive long-term stockholder value creation.
​
•
Aligning long-term pay outcomes with stockholder value creation over time. This necessitates tying a significant portion of each executive’s compensation to Company and individual performance, placing that compensation at risk.
​
The following key elements are used to compensate our executives:
•
Base salaries, representing the only fixed element of total direct compensation.
​
•
Annual incentives, currently consisting of a performance-based bonus under the Executive Officer Incentive Bonus Plan, which rewards achievement relative to Company goals, both financial and strategic in nature.
​
•
Long-term incentives, currently consisting of performance stock units and deferred stock awards, which link pay outcomes to long-term stockholder value creation. Executive officers may also purchase restricted stock units under our Management Stock Purchase Plan, providing additional alignment with stockholder value creation.
​
In addition, we provide our executive officers with other employee benefits and limited perquisites, which are primarily intended to maintain our competitive position for attracting and retaining executive

talent. However, in general, the Compensation Committee strives to mitigate the use of these non-performance-based forms of compensation without jeopardizing our ability to offer a compensation program that will attract and retain executives in a competitive market.
Benchmarking
Benchmarking is one factor, among many, that we rely on in establishing our compensation levels and program design. We use information regarding pay practices at other comparable companies in two respects. First, we use benchmarking information to evaluate whether our compensation practices are competitive in the marketplace in which we compete for executive talent. Second, we use marketplace information as one factor in assessing the reasonableness of our executive compensation.
During 2023, the Compensation Committee used an executive compensation peer group consisting of the following companies:

​ | A.O. Smith Corporation Barnes Group Inc. Chart Industries, Inc. Crane Co. EnPro Industries, Inc. | ​ | ​ | Franklin Electric Co., Inc. Graco Inc. Itron, Inc. ITT Corporation Mueller Industries, Inc. | ​ | ​ | Mueller Water Products, Inc. Nordson Corporation Pentair plc SPX Technologies, Inc. Zurn Water Solutions Corporation | ​

In May 2023, the Compensation Committee engaged Pearl Meyer to conduct a comprehensive review of our executive compensation peer group. Pearl Meyer used a rules-based process to evaluate the Company’s existing executive compensation peer group and to identify proposed changes to the peer group based on the similarity to Watts of the amount of their annual revenues, profitability, market capitalization and number of employees as well as the similarity of their industry, business models, scope of international operations, industrial classification codes, customers and analyst coverage, while attempting to minimize year-over-year changes in order to foster consistency in the benchmarking approach. Based on its review, Pearl Meyer recommended removing Altra Industrial Motion Corp. and Evoqua Water Technologies Corp. from the peer group since they were the subject of acquisition transactions and removing IDEX Corporation due to its high market capitalization. Pearl Meyer recommended replacing those companies with Chart Industries, Inc., Nordson Corporation and SPX Technologies, Inc. The Compensation Committee accepted Pearl Meyer’s recommendation and approved the new peer group. The executive compensation peer group had median 2022 annual revenue of approximately $2.04 billion, compared with our own revenue of approximately $1.98 billion for the same period. The peer group also had median market capitalization as of December 31, 2022 of approximately $3.76 billion, as compared to our market capitalization of approximately $4.87 billion.
Elements of Compensation
The following describes each of the elements of our compensation program for 2023.
Base Salary
We provide each of our executive officers with a fixed salary that provides a secure base of compensation in an amount that recognizes each officer’s role and responsibilities as well as experience, performance and contributions. The Compensation Committee considers base salary increases for our executive officers annually. The amount of any increase is based primarily on the executive officer’s performance, level of responsibilities, leadership, experience, employee retention and internal pay equity considerations and the external competitiveness of the officer’s base salary and overall total compensation. The Compensation Committee typically meets with the Chief Executive Officer annually to review proposed adjustments in the base salary amounts for our executive officers other than our Chief Executive Officer and in such review discusses each officer’s performance evaluation. The Compensation Committee also typically reviews the proposed adjustment in base salary and the performance of our Chief Executive Officer with the other independent members of the Board of Directors and conducts a separate discussion with our Chief Executive Officer regarding his performance. As part of its review, the Compensation Committee receives and discusses tally sheets setting forth the total compensation of our executive officers, including base salary, bonus potential, equity awards,

TABLE OF CONTENTS
retirement benefits, perquisites and other compensation, and information regarding the competitiveness of our compensation programs relative to companies in our benchmarking peer group and other industry survey data. Based on this review and its consideration of each named executive officer’s performance, in February 2023 the Compensation Committee approved the following base salary increases for our named executive officers effective as of April 1, 2023:

​ | Named Executive Officer | ​ | ​ | 2022 Base Salary ($) | ​ | ​ | Salary Increase as a Percentage of Prior Base Salary | ​ | ​ | 2023 Base Salary ($) | ​ | ​ | Rationale for Increase | ​
​ | Robert J. Pagano, Jr. | ​ | ​ | ​ | ​ | 1,009,100 | ​ | ​ | ​ | ​ | ​ | 4.0% | ​ | ​ | ​ | ​ | ​ | 1,050,000 | ​ | ​ | ​ | Merit | ​
​ | Shashank Patel | ​ | ​ | ​ | ​ | 500,000 | ​ | ​ | ​ | ​ | ​ | 4.0% | ​ | ​ | ​ | ​ | ​ | 520,000 | ​ | ​ | ​ | Merit | ​
​ | Andre Dhawan | ​ | ​ | ​ | ​ | 550,000 | ​ | ​ | ​ | ​ | ​ | 3.0% | ​ | ​ | ​ | ​ | ​ | 566,500 | ​ | ​ | ​ | Merit | ​
​ | Elie A. Melhem | ​ | ​ | ​ | ​ | 452,300 | ​ | ​ | ​ | ​ | ​ | 4.0% | ​ | ​ | ​ | ​ | ​ | 470,400 | ​ | ​ | ​ | Merit | ​
​ | Kenneth R. Lepage | ​ | ​ | ​ | ​ | 445,000 | ​ | ​ | ​ | ​ | ​ | 4.0% | ​ | ​ | ​ | ​ | ​ | 462,800 | ​ | ​ | ​ | Merit | ​

In February 2023, the Compensation Committee conducted a separate review of our Chief Executive Officer’s performance and base salary in conjunction with the other independent members of the Board. The independent members of the Board reviewed Mr. Pagano’s performance against his established goals for 2022 and input from Pearl Meyer with respect to the competitiveness of Mr. Pagano’s base salary relative to the Company’s executive compensation peer group. Based on this review and the Board’s assessment that Mr. Pagano had achieved his 2022 goals, including executing on driving innovation through new products and solutions as well as other global growth initiatives, driving productivity and supply chain savings initiatives, achieving the Company’s sustainability goals, and exceeding the 2022 financial plan, the Compensation Committee approved a 4.0% merit-based increase in Mr. Pagano’s base salary.
Annual Incentives
Under our Executive Officer Incentive Bonus Plan, annual bonus awards may be earned by our named executive officers based on the Company’s achievement of performance goals during each fiscal year. We offer our executives an opportunity to earn a bonus in order to focus our executives on execution against specific financial and strategic goals and reward performance based on achievement of such goals. For each of our executive officers, the Compensation Committee sets a target bonus amount expressed as a percentage of annual base salary rate. The Compensation Committee determines the target bonus amount for each executive officer based on a variety of factors, including competitive conditions for the executive officer’s position within our executive compensation peer group and in the broader employment market, length of employment, level of responsibility and experience, input from Pearl Meyer, and, in the case of executive officers other than the Chief Executive Officer, the recommendations of the Chief Executive Officer. For 2023, each of the named executive officer’s 2023 target bonus as a percentage of annual base salary rate remained unchanged from 2022. The 2022 target bonus amounts for our named executive officers were set as follows:

​ | ​ | ​ | ​ | Target as a Percent of Salary | ​ | ​ | Target in Dollars | ​
​ | Robert J. Pagano, Jr. | ​ | ​ | ​ | ​ | 110% | ​ | ​ | ​ | ​ | $ | 1,155,000 | ​ | ​
​ | Shashank Patel | ​ | ​ | ​ | ​ | 70% | ​ | ​ | ​ | ​ | $ | 364,000 | ​ | ​
​ | Andre Dhawan | ​ | ​ | ​ | ​ | 65% | ​ | ​ | ​ | ​ | $ | 368,225 | ​ | ​

The actual bonus payout for each named executive officer depends on the level of performance achieved with respect to various performance objectives. The relationship between the level of

performance achieved and overall bonus payout for each performance objective is as follows, with bonus payout levels interpolated for performance between Threshold and Target and between Target and Maximum:

​ | Performance Level | ​ | ​ | Bonus Payout as a % of Target | ​

For 2023, corporate performance objectives under our Executive Officer Incentive Bonus Plan were established in the first quarter by our Compensation Committee after consultation with our Chief Executive Officer and Pearl Meyer. The 2023 financial objectives for our named executive officers under the Executive Officer Incentive Bonus Plan consisted of a sales objective, an adjusted net income and adjusted operating income objective (for Mr. Melhem only), a free cash flow objective and individual performance objectives. Free cash flow represents the amount of cash generated by operations during the year less net capital expenditures. Our bonus objectives are intended to align the interests of our management team with the interests of our stockholders. We believe that the capital markets evaluate companies in our industry based primarily on their ability to grow their business profitably while maintaining adequate returns on their invested capital. Our bonus objectives provide an incentive to management to maintain a balanced approach to growth, with appropriate emphasis on revenues, profitability, cash flow and execution of strategic initiatives. If we are successful in meeting or exceeding our goals under these objectives, we believe that this will lead to the creation of additional value for our stockholders.
Under our Executive Officer Incentive Bonus Plan, the Compensation Committee may make certain adjustments to the performance objectives. Such adjustments may include but are not limited to: (i) a change in accounting principle, (ii) financing activities, (iii) expenses for restructuring or productivity initiatives, (iv) other non-operating items, (v) acquisitions or dispositions, (vi) the business operations of an entity acquired by the Company during the performance period, (vii) discontinued operations, (viii) stock dividend, split, combination or exchange of stock, (ix) unusual or extraordinary events, transactions or developments, (x) amortization of intangible assets, (xi) other significant income or expense outside the Company’s core on-going business activities, (xii) other nonrecurring items, (xiii) goodwill or intangible writeoffs, or (xiv) changes in applicable law.
For the individual performance objectives, each executive officer established several personal or team goals related to Company initiatives or segment initiatives that were aligned with the strategy of the business and the goals of our Chief Executive Officer, and such performance objectives were approved by the Chief Executive Officer and the Compensation Committee. For 2023, the individual performance objectives for our named executive officers established at the start of the performance period included strategic growth initiatives; environmental, social and governance (ESG) criteria; new product development and innovation initiatives, including smart and connected enabled products; driving productivity savings; employee safety performance; talent acquisition; diversity, equity and inclusion initiatives; and other key strategic initiatives.
The Compensation Committee, in consultation with our Chief Executive Officer, determined the relative weight to be assigned to each objective for 2023. The financial objectives for Messrs. Pagano, Patel, Lepage and Dhawan were based entirely on the performance of our Company as a whole. Since the responsibilities of Mr. Melhem were substantially tied to our APMEA business segment, most of

his bonus achievement was based on his segment performance. The following table shows the weighting assigned to each named executive officer for each performance objective:

A reconciliation of net income to adjusted net income, net cash provided by operating activities to free cash flow, and operating income to adjusted operating income is included in Item 7 of our Annual Report on Form 10-K filed with the SEC on February 21, 2024. APMEA segment free cash flow means free cash flow attributable to the APMEA reporting segment, and APMEA adjusted operating income means adjusted operating income attributable to the APMEA reporting segment. We define free cash flow as net cash provided by operating activities, less additions to property, plant and equipment, plus proceeds from the sale of property, plant and equipment.
​
The weighting of the 2023 performance objectives for our named executive officers was unchanged from 2022, as the Compensation Committee continued to place greater emphasis on the net income and operating income measures because it wanted management to emphasize growing the business profitably while maintaining its focus on encouraging productivity, cost containment and cash generation.
Our results for 2023 as determined in accordance with our Executive Officer Incentive Bonus Plan with respect to each financial performance measure for our Company as a whole and our APMEA segment are set forth in the following table:

The Compensation Committee reviewed with our Chief Executive Officer the performance of each of the other named executive officers with respect to their individual performance objectives. Based on this review and the recommendations of our Chief Executive Officer, the Compensation Committee determined that each of Messrs. Patel, Dhawan, Melhem and Lepage had achieved higher than the target level of performance with respect to his individual performance objectives. In recognition of their strong performance, the Compensation Committee approved a 16% weighted achievement for the individual performance component of the incentive bonus award for each of Mr. Patel, Mr. Dhawan and Mr. Lepage and 17% for Mr. Melhem. The Compensation Committee separately reviewed the performance of Mr. Pagano with respect to his individual performance objectives and determined that Mr. Pagano had exceeded his objectives and that he had done an excellent job developing, deploying and executing on the Company’s strategic growth initiatives, awarding him a 16% weighted achievement for the individual performance component of the incentive bonus award.

Long-Term Incentives
We provided long-term incentive compensation for our named executive officers during 2023 by granting performance stock units and deferred stock awards covering shares of class A common stock under our 2004 Stock Incentive Plan. In addition, our named executive officers are eligible to participate in our Management Stock Purchase Plan, which provides for the purchase of restricted stock units at a discount, as described below. The Compensation Committee believes in granting equity-based
38

TABLE OF CONTENTS
incentive compensation as an important component of our executive compensation program to encourage sustainable growth and long-term value creation, align the interests of our executives with those of our stockholders by exposing executives to stock price changes during the vesting or deferral periods, and to attract and retain executive talent.
Management Stock Purchase Plan
Our Management Stock Purchase Plan is intended to provide an incentive for our executives to purchase and hold more of our class A common stock, thereby more closely aligning their interests with the interests of our stockholders. The Compensation Committee approves the participants in the Management Stock Purchase Plan based on recommendations made by executive management. Participants were entitled to purchase restricted stock units under the Management Stock Purchase Plan at a discount of 20% from the closing sale price of our class A common stock on March 15, 2024 using up to 50% of their pre-tax 2023 performance bonus. The restricted stock units vest one-third each year beginning on the first anniversary of the date of grant. In addition, participants in the Management Stock Purchase Plan may elect to defer settlement of vested restricted stock units to a specified future date. For 2023, Messrs. Pagano, Melhem and Lepage each elected to contribute 50% of his annual performance bonus to the purchase of restricted stock units under the Management Stock Purchase Plan. Mr. Dhawan and Mr. Patel did not participate in the Management Stock Purchase Plan in 2023.
Long-Term Equity Incentive Awards
In 2023, we granted performance stock units and deferred stock awards to our executive officers, with each type of award accounting for 50% of the targeted value of long-term equity incentive awards for executive officers. The Compensation Committee believes that the use of performance stock unit awards and deferred stock awards in combination provides strong stockholder alignment, retention value, and the opportunity to leverage the value of awards up and down consistent with the Company’s stock price performance as well as Company performance over the long term.
The targeted value of the long-term equity incentive award grants made to our named executive officers was determined taking into account base pay and annual incentive values, a competitive analysis of executive compensation prepared by Pearl Meyer, and the Committee’s assessment of the appropriate mix of fixed versus variable and short-term versus long-term incentives. The Compensation Committee also considered each named executive officer’s role, potential long-term contribution, performance, experience and skills. Based on its analysis, the Compensation Committee determined that the performance stock units and deferred stock awarded to the Company’s Chief Executive Officer generally should have a targeted total value of approximately three-and-a-half times his annual base salary and the annual equity grant to each of our other named executive officers generally should have a targeted total grant date fair value of approximately one-and-a-half times his annual base salary. These are general guidelines and the Compensation Committee may change the value of awards based on an executive’s performance or other relevant factors. The following table shows the values used to determine the number of shares underlying the annual deferred stock awards and the target performance stock unit awards granted to our named executive officers in March 2023. In determining the number of shares underlying the awards granted to each named executive officer in 2023, we used a 30-day trailing average stock price. For this reason, the targeted values indicated below differ from the grant date fair values of the grants reflected in the Summary Compensation Table.

​ | Named Executive Officer | ​ | ​ | Performance Stock Unit Awards (Target Award) | ​ | ​ | Deferred Stock Awards | ​ | ​ | Total | ​
​ | Robert J. Pagano, Jr. | ​ | ​ | ​ | $ | 2,125,000 | ​ | ​ | ​ | ​ | $ | 2,125,500 | ​ | ​ | ​ | ​ | $ | 4,250,000 | ​ | ​

In connection with his hiring in 2022, Mr. Dhawan received a one-time equity grant with a value of $1,050,000

TABLE OF CONTENTS
to compensate Mr. Dhawan for the value of unvested equity awards he had received from his former employer. Because of the size of his new-hire grant, the value of Mr. Dhawan’s 2023 annual equity award was reduced. We expect that Mr. Dhawan will receive annual equity awards at full target value beginning in 2024.
Performance Stock Unit Awards. The performance stock units granted in 2023 will be settled in shares of the Company’s class A common stock following the end of a performance vesting period ending on December 31, 2025, with the number of shares to be delivered to be determined based on a payout matrix that determines what percentage of the target number of units will be delivered at each level of achievement relative to specified performance goals. The performance goals include a combination of the Company’s compound annual growth rate in revenue (“Revenue CAGR”) and return on invested capital (“ROIC”). Revenue CAGR measures the rate of our growth over time, while ROIC measures how efficiently and effectively we use capital to generate profits. For purposes of our performance stock unit awards, ROIC means the Company’s return on invested capital calculated as a percentage by dividing net operating profit after tax by average invested capital at the beginning and end of the relevant period. For the purposes of calculating ROIC, “net operating profit” will be adjusted to exclude the impact of all restructuring, foreign exchange, impairments, certain legal settlements, employee separation costs, certain product liability charges, the one-time impact of significant tax law changes, and retroactive tax law changes to the extent such items were not contemplated and included in the target upon which the ROIC goals were based. The Revenue CAGR and ROIC goals are also subject to adjustment to reflect the impact of any acquisitions or dispositions that occur during the performance period. The Compensation Committee selected these two measures primarily because they are generally accepted as two fundamental drivers of sustained stockholder value, they provide shorter line-of-sight measurements than many alternative measures and both measures are contained in the Company’s strategic plan. The number of shares delivered can range from zero to 200% of the target number of performance stock units initially awarded, depending on performance, and delivery generally requires employment throughout the three-year performance period. At the threshold level of performance, 60% of the target number of units would be earned. The level of performance required to attain the threshold performance metrics was set at a level of performance where the Compensation Committee believes that a reduced payout is appropriate and below which no payout is appropriate. The level of performance required to attain the target payout is designed to be reasonably challenging. The level of performance required to attain a maximum payout was set at a level of performance that the Compensation Committee deems exceptional. However, because the specific performance levels are related to our business strategy and are highly confidential, we do not publicly disclose them, as we believe their disclosure would provide our competitors and other third parties with significant insights regarding our confidential business strategies that could cause us substantial harm. Performance stock units do not grant dividend or voting rights to the holder during the performance period, but dividend equivalents are accrued and paid on shares delivered after the vesting date.
Settlement of the 2021 Performance Stock Unit Awards. The performance period for the 2021 performance stock unit awards concluded on December 31, 2023. The performance stock units granted in 2021 were settled in shares on February 7, 2024. The 2021 awards had their performance tied to a combination of Revenue CAGR and ROIC measures, as adjusted as provided in the grant agreements to account for acquisitions completed during the performance period. The performance targets for the

2021 performance stock units were as follows, with the payout percentage interpolated for performance between Threshold and Target and between Target and Maximum:

​ | 3 Year Revenue CAGR | ​ | ​ | ROIC | ​
​ | Below Threshold < 11.0% | ​ | ​ | Threshold 11.0% | ​ | ​ | Target 13.8% | ​ | ​ | Maximum 16.6% | ​
​ | Payout Percentage | ​
​ | Below Threshold <-0.5% | ​ | ​ | 0% | ​ | ​ | 60% | ​ | ​ | 75% | ​ | ​ | 100% | ​
​ | Threshold -0.5% | ​ | ​ | 60% | ​ | ​ | 60% | ​ | ​ | 75% | ​ | ​ | 125% | ​
​ | Target 1.0% | ​ | ​ | 80% | ​ | ​ | 80% | ​ | ​ | 100% | ​ | ​ | 150% | ​
​ | Maximum 2.5% | ​ | ​ | 100% | ​ | ​ | 100% | ​ | ​ | 150% | ​ | ​ | 200% | ​

The financial results for the 2021 awards were a Revenue CAGR of 10.4% and ROIC of 24.3%, both of which were above the maximum targeted amounts. According to the performance matrix, the resulting payout percentage achieved was 200% of the target award value. Mr. Pagano earned 28,052 shares, Mr. Patel earned 5,734 shares, Mr. Melhem earned 5,388 shares, and Mr. Lepage earned 5,302 shares.
Deferred Stock Awards. Half of the target value of our annual equity awards to our named executive officers is granted in the form of deferred stock awards. Deferred stock awards represent a contractual right to receive shares of the Company’s stock upon vesting of the award, provided that the recipient remains employed by the Company through the vesting date, except as provided under the retirement vesting policy described below. Upon the scheduled vesting date, the recipient will be issued shares of the Company’s class A common stock without restriction or risk of forfeiture. Recipients do not have voting or dividend rights with respect to deferred stock awards during the vesting period, but the deferred stock awards accrue dividend equivalents during the vesting period, which are then paid out to the recipient upon vesting. The 2023 deferred stock awards vest one-third each year over three years.
Benefits and Perquisites
We provide our executive officers with certain employee benefits and perquisites as a means of providing additional compensation that is designed to be competitive with other compensation provided by companies in our peer group.
Retirement benefits are provided through a qualified defined contribution 401(k) plan for all our full-time eligible employees who are United States residents, under which we provide a base contribution of 2% of an employee’s salary, regardless of whether the employee participates in the plan, and matching contributions up to 4%.
We also provide our named executive officers with a limited number of perquisites as part of their compensation arrangements, which we consider to be reasonable and consistent with competitive practice. These perquisites include a cash automobile allowance, supplemental disability insurance, a financial planning allowance and a comprehensive executive physical examination. The amount of the automobile allowance is determined by our Chief Executive Officer and reviewed by the Compensation Committee, and the Compensation Committee determines the maximum amount of our Chief Executive Officer’s automobile allowance. We reimburse our executives for certain financial planning expenses so they may focus more on their business responsibilities. We also typically reimburse recently hired executives for certain relocation-related expenses.
In addition, in connection with his assignment outside of the United States, we provided Mr. Melhem with customary expatriate benefits to address the unique circumstances arising from living and working abroad, as described in more detail in the Summary Compensation Table below.

TABLE OF CONTENTS​​
Claw Back Policy
We have adopted a compensation recovery policy as required by Rule 10D-1 under the Securities Exchange Act of 1934, as amended, and the corresponding listing standards of the New York Stock Exchange. This policy provides for the mandatory recovery (subject to limited exceptions) from current and former officers of incentive-based compensation that was erroneously received during the three years preceding the date that the Company is required to prepare an accounting restatement. Covered restatements include both a restatement to correct an error that is material to previously issued financial statements or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. The amount required to be recovered is the excess of the amount of incentive-based compensation received over the amount that otherwise would have been received had it been determined based on the restated financial measure.
Employment Agreements
None of our executive officers has an employment agreement with us.
Post-Termination Compensation and Change in Control Arrangements
Severance Benefits
We maintain an Executive Severance Plan, which provides severance benefits for our senior executives, including all our named executive officers. The Compensation Committee believes that the Executive Severance Plan is an important recruitment incentive for executives, provides a valuable retention incentive and is competitive with the practices of most of the companies in our executive compensation peer group. Under the Executive Severance Plan, a named executive officer involuntarily terminated for reasons not meeting the definition of cause under the Executive Severance Plan will receive a lump-sum payment equal to (i) an amount equal to twelve months of premiums the named executive officer would have to pay for COBRA medical coverage, and (ii) one year of base salary, except for Mr. Pagano who as Chief Executive Officer would receive two years of base salary. In connection with the receipt of any severance payments under the Executive Severance Plan, a named executive officer would be required to sign a written agreement that would contain a release of claims against the Company and such other restrictions, such as non-competition, non-solicitation and non-disparagement covenants, as the Compensation Committee determines are appropriate.
Change in Control Benefits
We believe that the consideration of a change in control transaction would create uncertainty regarding the continued employment of our executive officers. This uncertainty results from the fact that many change in control transactions result in significant organizational changes, particularly at the senior executive level. In order to encourage our executive officers to focus on seeking the best return for our stockholders and to remain employed with the Company during an important time when their prospects for continued employment following a change in control transaction are often uncertain, we provide certain key executives (including our named executive officers) with severance benefits in connection with certain terminations of employment occurring in connection with a change of control of the Company under the Executive Severance Plan. Further, we believe that providing these executive officers with severance benefits upon certain terminations in connection with a change in control is consistent with the practices of the companies in our executive compensation peer group and provides an important recruitment incentive for future executives. Under our Executive Severance Plan, if a named executive officer is involuntarily terminated without cause or resigns for good reason (as defined in the Executive Severance Plan) within 24 months following a change in control of the Company, or is involuntarily terminated without cause in the six months prior to such change in control, such named executive officer will receive an amount in cash equal to (i) 24 months of premiums the named executive officer would have to pay for COBRA medical coverage, and (ii) two times the sum of the named executive officer’s annual base salary and target annual bonus immediately prior to the change in control. In addition, the terminated executive would be entitled to full accelerated vesting and, as applicable, exercisability of unvested equity or equity-based awards of the Company that are not subject to performance vesting conditions and, for awards that are subject to performance vesting conditions,

accelerated vesting and, as applicable, exercisability at the greater of target or the level that would apply based on actual performance calculated as if the final day of the Company’s last completed fiscal quarter prior to the date of the employment termination were the final day of the applicable performance period. Should the amount of payments an executive were to receive under the Executive Severance Plan and any other plan in connection with a change in control cause the executive to be subject to the excise tax under Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), then the executive’s benefits would be reduced by an amount necessary to avoid application of the tax, but only if such reduction would result in a better after-tax result to the executive. In connection with the receipt of any severance benefits under the Executive Severance Plan, a named executive officer would be required to sign a written agreement that would contain a release of claims against the Company and such other restrictions, such as non-competition, non-solicitation and non-disparagement covenants, as the Compensation Committee determines are appropriate. In addition, our 2004 Stock Incentive Plan and Management Stock Purchase Plan provide that in connection with a change in control all unvested performance stock units, shares of restricted stock, deferred stock awards, stock options and restricted stock units will become fully vested.
Retirement Vesting
Beginning in 2019, the Company included “retirement vesting” provisions in the agreements for its deferred stock awards and performance stock unit awards. These provisions provide that an employee who retires from the Company after attaining age 55 and 10 years of service and who meets certain other requirements, including non-competition and non-solicitation requirements, would be allowed to continue to vest in his or her deferred stock awards for the duration of the vesting periods and would be entitled to receive a pro rata portion of his or her performance stock units based on the period of service elapsed during the performance period and the actual number of shares earned. Beginning in 2022, a provision was added to the award agreements that requires the employee to remain employed through the last working day of the grant year for the grant to be eligible for retirement vesting. We believe that these retirement vesting provisions create a strong retention incentive for our key employees, are consistent with the practices of the companies in our executive compensation peer group and provide an important recruitment incentive for future executives. Mr. Melhem is the only named executive officer who has qualified for retirement vesting.
Stock Ownership Guidelines
The Compensation Committee monitors compliance with the stock ownership guidelines approved by the Compensation Committee for all our executive officers. For 2023, our Chief Executive Officer was required to hold shares of our stock with a value of at least five times the amount of his base salary, our Chief Financial Officer was required to hold shares of our stock with a value of at least three times the amount of his base salary, and our other executive officers were required to hold shares of our stock with a value of at least twice their base salary. In determining the number of shares owned by an executive, the Compensation Committee considers shares held directly, the shares underlying restricted stock units purchased by the executive under our Management Stock Purchase Plan, deferred stock awards and shares of restricted stock, but not stock options or performance stock unit awards. Our officers are expected to comply with these requirements within five years of their appointment as an executive officer. The Compensation Committee evaluates compliance with these guidelines in connection with making its compensation decisions and recommendations at its regularly scheduled third quarter meeting. Compliance is typically measured based on stock ownership as of the last day of the second quarter. At the end of the second quarter of 2023, all our executive officers who had been executive officers of Watts for five or more years were in compliance with our stock ownership guidelines.

considers the tax and accounting consequences of utilizing various forms of compensation. However, the Compensation Committee believes that it is important to preserve flexibility in administering compensation programs in a manner designed to promote varying corporate goals. Accordingly, we have not adopted a policy regarding financial reporting and income tax consequences of our executive compensation programs.

The amounts shown in this column reflect the grant date fair value of performance stock units and deferred stock awards under our 2004 Stock Incentive Plan and the grant date fair value of the discount on the restricted stock units purchased under our Management Stock Purchase Plan determined in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718. A discussion of the assumptions used in calculating the amounts in this column may be found in Note 14 to our audited consolidated financial statements for the year ended December 31, 2023 included in our Annual Report on Form 10-K filed with the SEC on February 21, 2024, except that the fair value of the discount attributable to each restricted stock unit purchased under the Management Stock Purchase Plan on March 15, 2024 was estimated on the date of grant using the Black-Scholes-Merton Model based on the following weighted average assumptions:
​

​ | Expected life: | ​ | ​ | 3 years | ​
​ | Expected stock price volatility: | ​ | ​ | 28.9% | ​
​ | Expected dividend yield: | ​ | ​ | 0.8% | ​
​ | Risk-free interest rate: | ​ | ​ | 4.5% | ​

The risk-free interest rate is based on the U.S. treasury yield curve at the time of grant for the expected life of the restricted stock unit. The expected life, which is defined as the estimated period of time outstanding, of the restricted stock unit and the volatility were calculated using historical data. The expected dividend yield is our best estimate of the expected future dividend yield. Based on these assumptions, the weighted average grant date fair value of the discount on a restricted stock unit purchased on March 15, 2024 was $68.94. The grant date fair values of the performance stock units and deferred stock awards granted to each of our named executive officers during 2023 and the grant date fair value of the discount on the restricted stock units purchased by each of our named executive officers on March 15, 2024 were as follows:

The purchase price for restricted stock units under our Management Stock Purchase Plan is equal to 80% of the closing price of our class A common stock on the day on which the restricted stock units are awarded. The grant date fair value of the 20% discount on the restricted stock units purchased by each named executive officer has been included under the Stock Awards column as additional compensation to the named executive officer for each such year. The restricted stock units vest one-third each year beginning on the first anniversary of the date of grant. At the end of the deferral period specified by the named executive officer under the Management Stock Purchase Plan, we will issue one share of class A common stock for each vested restricted stock unit. Cash dividends equivalent to those paid on our class A common stock will be credited to the named executive officer’s account for non-vested restricted stock units and will be paid in cash to the named executive officer when such restricted stock units become vested. Dividends will also be paid in cash to individuals for vested restricted stock units held during any deferral period. The number of restricted stock units purchased with 2023 performance bonuses was determined by dividing the dollar amount of the bonus used to purchase the restricted stock units by $163.23, which was the discounted closing price of our class A common stock on the grant date, March 15, 2024. The number of restricted stock units purchased with 2022 and 2021 performance bonuses was determined by dividing the dollar amount of the bonus used to purchase the restricted stock units by $130.27 for 2022, which was the discounted closing price of our class A common stock on the grant date, March 15, 2023; and by $115.14 for 2021, which was the discounted closing price of our class A common stock on the grant date, March 15, 2022.

The Company has entered into a tax equalization arrangement with Mr. Melhem, the purpose of which is to ensure that Mr. Melhem pays no more or less income taxes as a result of his international assignment than he would if he lived and worked in the United States. Pursuant to this arrangement, if Mr. Melhem’s tax burden is higher as a result of his living and working in China than it would have been in the United States then the Company pays the excess, whereas if Mr. Melhem’s tax burden is lower, then Mr. Melhem pays the difference to the Company. This tax equalization arrangement resulted in Mr. Melhem owing the Company $174,260 during 2023 for the 2022 tax year, which repayment is not reflected in the Summary Compensation Table.

Type of award:
​
EIBP: Annual cash bonus award under our Executive Officer Incentive Bonus Plan
DSA: Deferred Stock Award under our 2004 Stock Incentive Plan
PSU: Performance Stock Unit award under our 2004 Stock Incentive Plan
(2)
The amounts in these columns indicate the threshold, target and maximum performance bonus amounts payable under our Executive Officer Incentive Bonus Plan prior to deducting any amounts the named executive officer elected to use to purchase restricted stock units under the Management Stock Purchase Plan. Each of our current named executive officers, except for Messrs. Dhawan and Patel, elected to use a portion of his 2023 performance bonus to purchase restricted stock units under our Management Stock Purchase Plan. See footnote (3) to the “Summary Compensation Table” for a description of the actual amount of performance bonus earned by each of the named executive officers for 2023, the amount of each named executive officer’s bonus that was used to purchase restricted stock units under the Management Stock Purchase Plan and the number of restricted stock units purchased. The potential performance bonus amounts payable under the Executive Officer Incentive Bonus Plan are based on the achievement of specific financial performance metrics and the achievement of individual strategic goals. The named executive officers would receive a bonus payout equal to 50% of their target bonus at the threshold level of performance and 200% of their target bonus at the maximum level of performance. If none of the threshold performance metrics are met, no performance bonus would be payable to the named executive officers.
​
(3)
The amounts in these columns indicate the threshold, target and maximum number of shares that the named executive officer could receive if an award payout is achieved under the Company’s performance stock unit awards. These potential share amounts are based on achievement of specific performance metrics. The named executive officer would receive 60% of the target number of shares at the threshold level of performance and 200% of the target number of shares at the maximum level of performance. If none of the threshold performance targets are met, then our named executive officers will not receive any shares.
​
(4)
The amounts shown in these columns represent the grant date fair value of each equity award as determined in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718. For the performance stock unit awards, the amounts shown assume that the target level of performance would be achieved with respect to the performance metrics, which we consider to be the probable outcome of the performance conditions as of the grant date. These are the amounts reflected in the “Summary Compensation Table.”

The value realized on vesting of deferred stock awards was determined by multiplying the number of shares that vested by the closing market price of our class A common stock on the vesting date. The value realized on vesting of restricted stock units purchased under the Management Stock Purchase Plan represents the difference between the purchase price paid by the named executive officer for the vesting shares and the closing market price of our class A common stock on the vesting date. The value of performance stock units was determined by multiplying the number of shares earned by $208.34, the closing market price of our class A common stock on December 29, 2023, which was the last trading day of the performance period.

TABLE OF CONTENTS​
Nonqualified Deferred Compensation
Under our Management Stock Purchase Plan, executives may elect to purchase restricted stock units, which vest one-third each year beginning on the first anniversary of the date of grant. However, shares are not delivered in settlement of the restricted stock units until the end of the deferral period selected by the named executive officer. Once vested, the restricted stock units constitute deferred compensation and are reported in the table below as contributions by the named executive officer. Restricted stock units that vested prior to 2023 and were issued at the end of their deferral period during 2023 are listed in the table as distributions of deferred compensation.
Prior to 2012, we maintained a Nonqualified Deferred Compensation Plan that was available to all our employees whose annual compensation was greater than $90,000. Of the named executive officers, only Mr. Lepage has deferred compensation under the Nonqualified Deferred Compensation Plan. Under the Nonqualified Deferred Compensation Plan, participants were allowed to defer up to 100% of base salary and bonus. Participant deferrals earn returns based on the participant’s selection from a list of investments that are generally the same as those provided in our 401(k) plan. The allocation of investments may be changed once each year. We did not make any matching contributions under the Nonqualified Deferred Compensation Plan.
Generally, account balances under the Nonqualified Deferred Compensation Plan may be paid at the earliest of termination of employment, normal retirement, early retirement, or becoming disabled as a lump sum or systematic installments over ten years. Account balances may be distributed prior to termination of employment only in the event of a financial hardship due to an unforeseeable emergency, but not in excess of the amount needed to meet the hardship. Distributions from the Nonqualified Deferred Compensation Plan to our named executive officers cannot be made until at least six months after termination of employment. Mr. Lepage did not receive any distributions, or make any withdrawals, from the Nonqualified Deferred Compensation Plan during 2023.
Beginning in 2019, the award agreements for our deferred stock awards and performance stock unit awards under our 2004 Stock Incentive Plan provide that an employee who retires from the Company after attaining age 55 and 10 years of service and who meets certain other requirements, including non-competition and non-solicitation requirements, will be allowed to continue to vest in his or her deferred stock awards for the duration of the vesting periods and will be entitled to receive a pro rata portion of his or her performance stock units based on the period of service elapsed during the performance period and the actual number of shares earned. Beginning in 2022, a provision was added to the award agreements that requires the employee to remain employed through the last working day of the grant year for the grant to be eligible for retirement vesting. Of our named executive officers, only Mr. Melhem is currently eligible for this retirement benefit.

Potential Payments Upon Termination or Change in Control
Executive Severance Plan
Our Executive Severance Plan covers all our named executive officers. Under the Executive Severance Plan, a named executive officer involuntarily terminated for reasons not meeting the definition of cause under the Executive Severance Plan will receive a lump sum amount equal to (i) twelve months of premiums the named executive officer would have to pay for COBRA medical coverage, and (ii) one year of base salary, except for Mr. Pagano who as Chief Executive Officer would receive two years of base salary. In connection with the receipt of any severance payments under the Executive Severance Plan, a named executive officer would be required to sign a written agreement that would contain a release of claims against the Company and such other restrictions, such as non-competition, non-solicitation and non-disparagement covenants, as the Compensation Committee determines are appropriate.
If a named executive officer is involuntarily terminated without cause or resigns for good reason (as defined in the Executive Severance Plan) within 24 months following a change in control of the Company, or is involuntarily terminated without cause in the six months prior to such change in control, such named executive officer will receive a lump sum amount equal to (i) 24 months of premiums the named executive officer would have to pay for COBRA medical coverage, and (ii) two times the sum of the named executive officer’s annual base salary and target annual bonus immediately prior to the change in control (less any payments previously received under the Executive Severance Plan).

In addition, under the Executive Severance Plan, if a participant is involuntarily terminated without cause or resigns for good reason (as defined in the Executive Severance Plan) within 24 months following a change in control of the Company, or is involuntarily terminated without cause in the six months prior to such change in control, such participant would be entitled to full accelerated vesting and, as applicable, exercisability of unvested equity or equity-based awards of the Company that are not subject to performance vesting conditions and, for awards that are subject to performance vesting conditions, accelerated vesting and, as applicable, exercisability at the greater of target or the level that would apply based on actual performance calculated as if the final day of the Company’s last completed fiscal quarter prior to the date of the employment termination were the final day of the applicable performance period. The total number of unvested shares of deferred stock awards, performance stock units and restricted stock units that would vest and the value of such acceleration in the event of such a termination as of December 31, 2023 are the same as those set forth in the table under “Equity Plans” below in the “Change in Control” row.
Equity Plans
Under our 2004 Stock Incentive Plan and the award agreements thereunder, upon the termination of employment of a participant for any reason other than death or disability, all unvested performance stock units and deferred stock awards immediately terminate. If a participant’s employment is terminated by reason of death or disability, all deferred stock awards immediately vest in full. For performance stock units, if a participant’s employment is terminated due to death or disability during the last twelve months of the performance period, the participant will receive the number of shares actually earned and vested at the end of the performance period as if the participant had not terminated employment. If the participant’s employment is terminated due to death or disability within the first twenty-four months of the performance period, the participant will receive the target number of shares pro-rated based on the portion of the performance period during which the participant was employed.
In addition, the award agreements for our deferred stock awards and performance stock unit awards provide that an employee who retires from the Company after attaining age 55 and 10 years of service and who meets certain other requirements, including non-competition and non-solicitation requirements, will be allowed to continue to vest in his or her deferred stock awards for the duration of the vesting periods and will be entitled to receive a pro rata portion of his or her performance stock units based on the period of service elapsed during the performance period and the actual number of shares earned. Beginning in 2022, a provision was added to the award agreements that requires the employee to remain employed through the last working day of the grant year for the grant to be eligible for retirement vesting. Of our named executive officers, only Mr. Melhem is currently eligible for this retirement benefit, as described in more detail in the Nonqualified Deferred Compensation Table above.

TABLE OF CONTENTS
Under our Management Stock Purchase Plan, upon the termination of employment of a participant for any reason, including death or disability, all vested restricted stock units will be exchanged for shares of class A common stock and the participant will receive a cash payment equal to the lesser of (i) the original purchase price paid for the unvested restricted stock units plus interest, or (ii) an amount equal to the number of unvested restricted stock units multiplied by the fair market value of our class A common stock on the termination date.
Our 2004 Stock Incentive Plan and Management Stock Purchase Plan provide that in connection with a change in control all unvested deferred stock awards, performance stock units and restricted stock units will become fully vested. The table below sets forth the number of unvested shares of deferred stock awards, performance stock units and restricted stock units that would vest and the value of such acceleration in the event of certain terminations or a change in control as of December 31, 2023.

In the event of a change of control during the performance period, the performance stock unit award agreement provides that the participant would receive a number of shares equal to the greater of (i) the target number of performance stock units granted to the participant, or (ii) the number of performance stock units that would be earned based on the Company’s performance determined as if the Company’s last quarter end prior to the change of control was the last day of the performance period. The value of unvested performance stock units in this column was calculated using 150% of the target number of performance stock units granted to the named executive officer in 2023, 200% of the target number of performance stock units granted to the named executive officer in 2022, and the actual number of shares earned under the performance stock units granted to the named executive officer in 2021.

In the case of death or disability, in accordance with the performance stock unit award agreement, the number of shares in this column reflects the actual number of shares earned for the performance stock units granted in 2021, and for the performance stock units granted in 2022 and 2023 the number of shares reflects the target number of shares pro-rated based on the portion of the performance period during which the participant was employed.

As of December 31, 2023, Mr. Melhem was the only named executive officer who had met the eligibility requirements for retirement vesting. In the case of retirement, Mr. Melhem would continue to vest in his deferred stock awards for the duration of the vesting periods, and the numbers shown in the table reflect the number of shares that would continue to vest over such periods. In addition, Mr. Melhem would remain eligible to earn a pro-rata portion of his performance stock units based on the period of service elapsed during the performance period and the actual number of shares earned based on the Company’s achievement against the performance metrics for the applicable performance period. For Mr. Melhem’s performance stock units, the numbers shown reflect the actual number of shares earned for the performance stock units granted in 2021, and for the performance stock units granted in 2022 and 2023, the numbers shown reflect the target number of shares pro-rated based on the portion of the performance period during which would have been employed had he retired as of December 31, 2023.

Pay Ratio Disclosure
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the median annual total compensation of our employees and the annual total compensation of Robert J. Pagano, Jr., our Chief Executive Officer. For 2023:
•
the median of the annual total compensation of all employees of the Company (other than our Chief Executive Officer) was $48,675; and
​
•
the annual total compensation of our Chief Executive Officer was $7,537,395.
​
Based on this information, for 2023 the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of all employees was approximately 155 to 1.
As permitted under the SEC rules, to determine our median employee, we used a definition that was not the equivalent of the total compensation reflected in the Summary Compensation Table and instead chose base pay as our measure since our incentive and equity plans do not have broad participation across our employee population. We calculated annual base pay using a reasonable estimate of hours worked during 2023 for hourly employees and upon base pay earned in 2023 for salaried employees. Using the compiled data, we identified the median employee as of December 31, 2023. For our 2023 pay ratio disclosure, we determined the median employee’s total 2023 compensation using the same criteria as in the Summary Compensation Table.

​ | PROPOSAL 2 ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION | ​

Maintaining good corporate governance is one of our highest priorities, and as part of that commitment we welcome input from our stockholders on our corporate governance and executive compensation practices. One of the methods we use to receive input from our stockholders is, in accordance with Section 14A of the Exchange Act, we ask our stockholders to vote annually to approve a nonbinding, advisory resolution on the compensation of our named executive officers as disclosed in this proxy statement.
We seek to closely align the interests of our named executive officers with the interests of our stockholders. Our compensation programs are designed to reward our named executive officers for the achievement of short-term and long-term strategic and operational goals and the achievement of increased total stockholder return, while at the same time avoiding the encouragement of unnecessary or excessive risk-taking. We encourage you, before voting, to read the Compensation Discussion and Analysis section of this proxy statement and to review all compensation information in light of the information the Compensation Discussion and Analysis section provides about our alignment of pay with performance and our compensation philosophy. We believe our compensation programs reflect a strong pay for performance philosophy and have been effective at incenting the achievement of financial performance goals and the creation of stockholder value. Examples of practices and policies that we have implemented to ensure effective governance of our compensation plans include:
•
Our incentive programs are linked to key financial and non-financial performance metrics, which we believe will help drive long-term stockholder value.
​
•
Our executives are subject to robust stock ownership guidelines.
​
•
Our executives are subject to a compensation recovery policy, or “claw back” policy, which provides for the mandatory recovery (subject to limited exceptions) from current and former officers of incentive-based compensation that was erroneously received during the three years preceding the date that the Company is required to prepare an accounting restatement.
​
•
The Compensation Committee has the authority to hire independent counsel and other advisors and consults regularly with an independent external compensation consultant.
​
•
The Compensation Committee annually conducts a review and assessment of risk as it relates to our compensation policies and practices.
​
•
Our Insider Trading Compliance Policy prohibits hedging and short sale transactions, and no employee, officer or director may pledge Company securities as collateral.
​
•
None of our executive officers has an employment agreement with us.
​
•
We do not provide excise tax gross-ups under any of our change in control severance arrangements.
​
The vote on this resolution is advisory, which means that the vote is not binding on the Company, our Board of Directors or the Compensation Committee of the Board of Directors. However, we value the opinions of our stockholders and to the extent there is any significant vote against the compensation of our named executive officers, the Compensation Committee will evaluate whether any actions are necessary or advisable to address the concerns of our stockholders. Our Board of Directors has adopted a policy of providing for annual stockholder advisory votes on executive compensation. Unless our board of directors modifies its policy on the frequency of future stockholder votes on executive compensation, the next such advisory vote will be held at the 2025 annual meeting of stockholders.
We believe our compensation program and policies described in this proxy statement are aligned with stockholder interests and are worthy of stockholder support. Accordingly, we ask our stockholders to approve the following resolution at the Annual Meeting:
RESOLVED, that the compensation paid to our named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby APPROVED.

​ | AUDIT COMMITTEE REPORT | ​

The responsibilities of the Audit Committee are set forth in the charter of the Audit Committee. The Audit Committee, among other matters, is responsible for assisting the Board in its oversight of the integrity of the Company’s financial statements, compliance with legal and regulatory requirements, the qualifications, independence and performance of the Company’s independent registered public accounting firm, and the performance of the Company’s internal audit function. The Audit Committee’s oversight role includes the appointment and evaluation of the Company’s independent registered public accounting firm, oversight of the Company’s systems of internal control over financial reporting, a review of management’s assessment and management of risk, a review of the annual independent audit of the Company’s consolidated financial statements and internal control over financial reporting, review of the Company’s Code of Business Conduct, the establishment of “whistle-blowing” procedures, and oversight of other compliance matters.
The Audit Committee reviewed and discussed the Company’s audited consolidated financial statements for the year ended December 31, 2023 with management. The Audit Committee also reviewed and discussed the audited consolidated financial statements, the audit of internal control over financial reporting and the matters required to be discussed with KPMG LLP, the Company’s independent registered public accounting firm, by the applicable requirements of the Public Company Accounting Oversight Board and the Securities and Exchange Commission. The Audit Committee received from KPMG the written disclosures and letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and discussed with KPMG the matters disclosed in this letter and their independence. The Audit Committee also considered whether KPMG’s provision of tax and other non-audit related services to the Company was compatible with maintaining their independence.
Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the Company’s audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

​ | PROPOSAL 3 RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM | ​

Although Delaware law does not require that the appointment by the Audit Committee of our independent registered public accounting firm be approved each year by the stockholders, the members of the Audit Committee and the other members of the Board believe it is appropriate to submit the appointment of the independent registered public accounting firm to the stockholders for their ratification. The Audit Committee appointed KPMG LLP as our independent registered public accounting firm for 2024, and the Audit Committee and Board recommend that the stockholders ratify such appointment. If the stockholders do not ratify the appointment of KPMG, the Audit Committee will reconsider its appointment.
We expect that representatives of KPMG will be present at the Annual Meeting. They will be given the opportunity to make a statement if they desire to do so and will also be available to respond to appropriate questions from stockholders.
During 2022 and 2023, KPMG provided various audit, audit-related, tax and other non-audit services to us. The Audit Committee has adopted policies and procedures that require the Audit
61

TABLE OF CONTENTS
Committee to pre-approve all audit and non-audit services performed by KPMG in order to ensure that the provision of such services does not impair KPMG’s independence. In 2023, the Audit Committee adopted a new policy (the “Pre-Approval Policy”) that sets forth the procedures and conditions pursuant to which audit and non-audit services proposed to be performed by the independent auditor may be pre-approved. The Pre-Approval Policy generally provides that we will not engage an independent auditor to render any audit, audit-related, tax or permissible non-audit service unless the service is either (i) explicitly approved by the Audit Committee (“specific pre-approval”) or (ii) entered into pursuant to the pre-approval policies and procedures described in the Pre-Approval Policy (“general pre-approval”). Unless a type of service to be provided by the independent auditor has received general pre-approval by the Audit Committee, it requires specific pre-approval by the Audit Committee.
For both types of pre-approval, the Audit Committee considers whether such services are consistent with the SEC’s and the Public Company Accounting Oversight Board’s rules on auditor independence. The Audit Committee will also consider whether the independent auditor is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with the Company’s business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Company’s ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor should necessarily be determinative.
In connection with the Pre-Approval Policy, the Audit Committee may annually review and pre-approve any services (and related fee levels or budgeted amounts) that may be provided by the independent auditor without first obtaining specific pre-approval from the Audit Committee or the Chair of the Audit Committee. The Audit Committee may revise the list of such general pre-approved services from time to time, based on subsequent determinations.
The aggregate fees billed for professional services by KPMG in 2022 and 2023 for audit, audit-related, tax and other non-audit services were:

​ | Type of Fees | ​ | ​ | 2022 | ​ | ​ | 2023 | ​
​ | Audit Fees: | ​ | ​ | ​ | $ | 3,343,608 | ​ | ​ | ​ | ​ | $ | 3,889,039 | ​ | ​
​ | Audit-Related Fees: | ​ | ​ | ​ | $ | 15,310 | ​ | ​ | ​ | ​ | $ | 24,649 | ​ | ​
​ | Tax Fees: | ​ | ​ | ​ | $ | 43,014 | ​ | ​ | ​ | ​ | $ | 126,032 | ​ | ​
​ | All Other Fees: | ​ | ​ | ​ | ​ | — | ​ | ​ | ​ | ​ | $ | 200,000 | ​ | ​
​ | Total: | ​ | ​ | ​ | $ | 3,401,932 | ​ | ​ | ​ | ​ | $ | 4,239,720 | ​ | ​

Audit fees primarily include fees we paid KPMG for professional services for the audit of our annual financial statements included in our annual report on Form 10-K, review of financial statements included in our quarterly reports on Form 10-Q, and for services that are normally provided in connection with statutory and regulatory filings or engagements, such as consents. Audit fees for 2022 and 2023 also include the audit of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act of 2002. Audit-related fees were for preparation of statutory financial statements and statutory financial statement tagging. For 2023 and 2022, 0% and 3%, respectively, of these audit-related fees were approved by the Audit Committee pursuant to Rule 2‑01(c)(7)(i)(C) of Regulation S-X. Tax fees include fees for review or preparation of tax returns and advice on indirect taxes. Other non-audit fees include gap assessment and related services with respect to new ESG regulations.
The Audit Committee and the Board of Directors recommend that stockholders vote “FOR” the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for 2024.

​ | HOUSEHOLDING OF ANNUAL MEETING MATERIALS | ​

Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements, annual reports and notices of Internet availability of proxy materials. This means that only one copy of such materials may have been sent to multiple stockholders in your household. However, a proxy card or voting instruction form will be delivered for each stockholder in your household. We will promptly deliver a separate copy of any such document to you if you write or call us at the following address or telephone number: Watts Water Technologies, Inc., 815 Chestnut Street, North Andover, MA 01845, Attention: Corporate Secretary, (978) 688-1811, or you can request a copy of any such document by visiting https://materials.proxyvote.com/942749. If you want to receive separate copies of the annual report, proxy statement and notice of Internet availability of proxy materials in the future, or if you are receiving multiple copies and would like to receive only one copy for your household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and telephone number.

​ | STOCKHOLDER PROPOSALS | ​

In order for any stockholder proposal to be included in the proxy statement for our 2025 Annual Meeting pursuant to Exchange Act Rule 14a-8, such proposal must be received at our principal executive offices, 815 Chestnut Street, North Andover, MA 01845, Attention: Corporate Secretary, not later than December 9, 2024 and must satisfy certain rules of the SEC.
Director nominations and proposals of stockholders may also be submitted to us for consideration at the 2025 Annual Meeting if certain conditions set forth in our by-laws are satisfied, but will not be included in the proxy materials unless the conditions set forth in Exchange Act Rule 14a-8 are satisfied.

Stockholder proposals received by us outside of these dates will be considered untimely received for consideration at such Annual Meeting. If the date of the 2025 Annual Meeting is held on a date more than seven days (in the case of director nominations) or ten days (in the case of other stockholder proposals) prior to the anniversary date of the 2024 Annual Meeting, we will publicly disclose such change, and nominations or other proposals to be considered at the 2025 Annual Meeting must be received by us not later than the 20th day after such disclosure (or, if disclosed more than 75 days prior to such anniversary date, the later of 20 days following such disclosure or 75 days before the date of the 2025 Annual Meeting). If the date described in the preceding sentence is not a business day, nominations or other proposals may be received on the next succeeding business day. To submit a nomination or other proposal, a stockholder should send the nominee’s name or proposal and appropriate supporting information required by our by-laws to the attention of our Corporate Secretary at the address provided above. To be considered, all nominations or proposals must comply with the requirements of our by-laws, a copy of which may be obtained without charge by sending a request to our Corporate Secretary at our principal executive offices.
In addition to satisfying the foregoing requirements under our by-laws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees for the 2025 Annual Meeting must include the additional information required by Rule 14a‑19(b) under the Exchange Act in any notice of director nomination submitted to the Company.
