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, "FOR" the amendment to our Certificate of Incorporation, 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.

        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 approval of the amendment to our Certificate of Incorporation and 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

Table of Contents

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.

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 of the director nominees, withhold your vote from all of 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 not be included in the vote tally for the election of directors and 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 compensation.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: Approval of the Amendment to Our Certificate of Incorporation

        Under our Certificate of Incorporation and the Delaware General Corporation Law, approval of the amendment to our Certificate of Incorporation requires the affirmative vote of the holders of a majority of the votes represented by the outstanding shares of class A common stock and class B common stock, voting together as a class. In addition, the amendment requires the affirmative vote of the holders of a majority of the issued and outstanding shares of class A common stock and the holders of a majority of the issued and outstanding shares of class B common stock, each voting as a separate class. An abstention will have the same effect as a vote against the proposed amendment to our Certificate of Incorporation because such proposal requires an affirmative vote by a majority of the shares outstanding. Because brokers have discretionary authority under NYSE rules to vote street name shares on Proposal 3, we do not expect any broker non-votes on this proposal.

Proposal 4: 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 3,4, we do not expect any broker non-votes in connection with this proposal.

        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.

        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.

Director Compensation

        Our non-employee directors are compensated for their service as directors. During 2017,2018, our Chief Executive Officer, Robert J. Pagano, Jr., was the only member of our Board of Directors who was an employee of Watts, and he did not receive any additional compensation for his service as a director. Our current compensation arrangements for non-employee directors were set in July 2014,effective as of the first quarter of 2019, 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. The Compensation Committee andThis review included a consideration of non-employee director compensation practices among a peer group of companies identical to the peer group roster we use when benchmarking executive pay practices. As a result of its review of Pearl Meyer's analysis, in November 2018 the Board reassessedapproved an increase in the competitiveness of our compensation arrangementsannual cash retainer for non-employee directors from $70,000 to $75,000, an increase in October 2016the additional annual retainer for the Chairperson of the Board from $60,000 to $90,000 and determined that such arrangements were sufficiently competitive and did not make any changes.an increase in the value of the annual grant of Class A common stock to non-employee directors from $100,000 to $110,000. Set forth below is a summary of all of the current annual compensation arrangements for our non-employee directors.

        We also reimburse non-employee directors for reasonable out-of-pocket expenses incurred in connection with attending Board and committee meetings and for fees and reasonable out-of-pocket expenses for their attendance at director education seminars and programs they attend at the request of the Board.in connection with their Board service. 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. Such awards are not subject to vesting or any other conditions or restrictions. We have adoptedUnder our 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. In 2018, we continued our practice thatof determining the number of shares awarded to our non-employee directors is determined using a twelve-month trailing average stock price, which may resultresulted in a grant date fair value that is more or less than the established value of the annual stock grant to non-employee directors.directors, which at the time of the grant was $100,000. However, in February 2019, the Board decided that beginning in 2020 the Board would change its practice for determining the number of shares to be awarded to non-employee directors by using a three-month trailing average stock price. On August 1, 2017,July 30, 2018, we granted 1,5691,356 shares of class A common stock to each of Messrs. Ayers, Conway, Dunbar, Hansen, Kissel, Noonan and Reitmeier and Ms.Mses. Goeser and Raines. Non-employee directors who are first elected to our Board during the year receive a pro-rated award of shares for the remaining portion of the then-current Board term. Messrs. Dunbar and Hansen wereMs. Goeser was elected to the Board on February 8, 2017March 12, 2018 and each received an award of 415372 shares of class A common stock, which represented one-quarter of the value of the annual grant of stock awarded to non-employee Board members for the 2016-20172017-2018 term.

Table of Contents

        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. Messrs. Ayers, Conway and Reitmeier and Ms. Raines elected to defer receipt of their 20172018 stock awards.

Table of Contents

        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 $210,000 for 2017.2018. 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 quarter. At the end of the second quarter of 2017,2018, all of 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, 2017.2018.

20172018 DIRECTOR COMPENSATION

Table of Contents

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.

        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.

        In 2017,2018, our Board met foursix times and each incumbent director who was a member of our Board during 20172018 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, strategic and reputational 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, 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 the next 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.

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

Table of Contents

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, each quarter the Board 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 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.

Board Leadership Structure

        We separate the roles of Chief Executive Officer and Chairperson of the Board in recognition of the differences between the two roles. Our Chief Executive Officer is responsible for our operational management, providing day-to-day leadership and managing our performance. The Chairperson of the Board provides guidance to our Chief Executive Officer, works with our Chief Executive Officer to set the agenda for Board meetings and presides over meetings of the Board, including executive sessions of the non-management and independent directors.

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 Nominating and Corporate Governance 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 athttp:https://www.wattswater.comwww.watts.com. Any amendments to, or waivers of, the Code of Business Conduct which apply to our Chief Executive Officer, Chief Financial Officer, Corporate Controller or any person performing similar functions will be disclosed on our website within four business days of the date of such amendment or waiver.

Director Independence

        As of February 28, 2018,March 1, 2019, members of the Horne family beneficially owned 6,329,2906,229,290 shares of our class B common stock that are subject to The George B. Horne Voting Trust Agreement—1997. These shares represented 69.1%approximately 68.8% 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 of 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 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.

Table of Contents

        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.

Table of Contents

Material relationships can include commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships. The Nominating and Corporate Governance Committee annually evaluates the independence of each non-employee director nominee and makes recommendations to the Board. In making its recommendations, the Nominating and Corporate Governance 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 Nominating and Corporate Governance 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 Nominating and Corporate Governance Committee, the Board determined that eightseven of our tennine current directors (Messrs. Ayers, Conway, Dunbar, Hansen, Kissel and Reitmeier and Mses. Goeser and Raines) are independent under NYSE rules and that the composition of our Board therefore complies with our Corporate Governance Guidelines. With respect to Mr. Noonan, the Board determined that he is a non-management director under NYSE rules, but not independent under NYSE rules 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.

Horne Family Board Participation

        As described above, as of February 28, 2018March 1, 2019 Timothy P. Horne controlled approximately 69.1%68.8% 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 20182019 to serve a one-year term beginning on the date of our 20182019 Annual Meeting and ending on the date of our 20192020 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 Watts.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 Watts,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 athttp:https://www.wattswater.comwww.watts.com..

Table of Contents

Executive Sessions

        In accordance with our Corporate Governance Guidelines, our non-management directors meet in executive session at least quarterly. The Chairperson of the Board or, in his or her 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, individual directors or non-management or independent directors as a group. All correspondence will be forwarded to the intended recipient(s).

Annual Meeting Attendance

        Directors are encouraged to attend our annual meetings of stockholders. Nine of our directors attended the 20172018 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 Nominating and Corporate Governance 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 Nominating and Corporate Governance Committee in the "Investors" section of our website athttp:https://www.wattswater.comwww.watts.com. The Board also appoints from time to time ad hoc committees to address specific matters.

Table of Contents

Table of Contents

        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. During 2017,2018, the Compensation Committee held six meetings. The Chairperson of the Compensation Committee works with management to establish the agenda for each meeting. Compensation Committee members receive and review materials in advance of each meeting. These materials include information that management believes will be helpful to the Compensation Committee as well as materials that members 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

Table of Contents

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 FebruaryMay 2018, 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 Nominating and Corporate Governance Committee will consider for nomination to the Board candidates recommended by stockholders. Recommendations should be sent to our Corporatecorporate Secretary at our principal executive offices and marked to the attention of the Nominating and Corporate Governance Committee. Recommendations must be in writing and must contain the information set forth in Section IV.C of the Nominating and Corporate Governance Committee charter, which is available in the Investors section of our website athttp:https://www.wattswater.comwww.watts.com, or on written request to our corporate Secretary at our principal executive offices.

        In addition to considering candidates suggested by stockholders, the Nominating and Corporate Governance Committee may consider potential candidates suggested by current directors, Company officers, employees, third-party search firms and others. The Nominating and Corporate Governance Committee screens all potential candidates in the same manner regardless of the source of the recommendation. The Nominating and Corporate Governance Committee's review is typically based on any written materials provided with respect to the potential candidate. The Nominating and Corporate Governance 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 Nominating and Corporate Governance Committee or the Board, by following the procedures described later in this proxy statement under "Stockholder Proposals".

        In 2017, 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 Louise K. Goeser to the Board on March 12, 2018. Ms. Goeser is standing for election by our stockholders as a member of our Board of Directors for the first time at the 2018 Annual Meeting.

Criteria and Diversity

        We believe that our Board should be composed of directors who, as a group, have the experience 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 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 Nominating and Corporate Governance Committee must be satisfied that the recommended nominee has, at a minimum:

•

the highest personal and professional integrity;

Table of Contents

•

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.

The Nominating and Corporate Governance Committee also considers experience in our industry or markets, international business experience, experience serving on the boards of public companies, experience acquiring companies and diversity of background and experience to be favorable characteristics in evaluating recommended nominees. In addition, the nominee must not serve on more than two public company boards in addition to our Board.

        Our Corporate Governance Guidelines and our Nominating and Corporate Governance Committee charter specify that the Nominating and Corporate Governance Committee and the Board understand 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

Table of Contents

things as gender, age, race, sexual orientation, national origin, religion, political affiliation, marital status, disability, and geographic background. The Nominating and Corporate Governance Committee does not assign specific weights to particular criteria, and no particular criterion is necessarily applicable to all prospective nominees. The Nominating and Corporate Governance 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.

Compensation Committee Interlocks and Insider Participation

        During 2017,2018, Robert L. Ayers, Richard J. Cathcart, Christopher L. Conway, Louise K. Goeser and Jes Munk Hansen 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 20172018 is or has been an executive officer or employee of Watts.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 and directors under our Insider Trading Compliance Policy. We also prohibit all employees and directors from purchasing our securities on margin or holding any of our securities in margin accounts. In addition, no employee or director may pledge any of our securities as collateral for a loan. Finally, all employees 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

Table of Contents

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 Nominating and Corporate Governance 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 Nominating and Corporate Governance Committee after full disclosure of the

Table of Contents

related person's interest in the transaction. As appropriate for the circumstances, the committee will review and consider:

•

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 Nominating and Corporate Governance Committee may approve or ratify the transaction only if it determines that, under all of the circumstances, the transaction is in, or is not inconsistent with, our best interests. The Nominating and Corporate Governance 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 dollars 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 Watts;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

        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 the executive officers named in the Summary Compensation Table; and



•

all of 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 28, 2018.March 1, 2019.

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 28, 2018March 1, 2019 are deemed to be outstanding, but are not deemed to be outstanding for the purpose of determining the percentages for any other stockholder.

Significant Changes in Our Senior Leadership Team During the Year

        This past year we welcomed Shashank Patel as our new Chief Financial Officer, and Todd Trapp left the Company. Mr. Trapp resigned as our Chief Financial Officer in April 2018 and, after a comprehensive search process, Mr. Patel joined the Company in July 2018. As an inducement to join our Company, Mr. Patel received a special performance stock unit award in connection with his hiring that is entirely performance-based in that the number of shares ultimately issued to Mr. Patel, if any, will be determined based on the Company's performance relative to a set of goals with respect to revenue growth and return on invested capital that we consider challenging. Mr. Patel also received a time-vesting restricted stock award that was intended to replace the value of equity grants from his prior employer that he forfeited in order to join us. These initial grants were specific to the hiring of Mr. Patel and are not intended to be continuing.

Alignment of Pay with Performance

        A substantial portion of each executive's compensation opportunity 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

        Other compensation decisions in 20172018 reflected our compensation philosophy, as set forth in more detail below. Each of our named executive officers other than Mr. Patel received base salary increases in 2017,2018, reflecting a consideration of individual and Company performance as well as competitive position relative to market, among other factors.

Other Practices and Policies to Promote Effective Compensation Governance

        Examples of practices and policies that the Committee has implemented to ensure effective governance of compensation plans include:

•

Our executives are subject to robust stock ownership guidelines.

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. For the purposes of calculating ROIC, "net operating profit" will be adjusted to exclude the impact of all restructuring, foreign exchange, impairments, legal settlements, employee separation costs, product liability charges, pension plan and supplemental employee retirement plan terminations 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 shareholder value, they provide shorter line-of-sight measurements than many alternative measures and both measures are contained in the Company's strategic plan. The Revenue CAGR and ROIC goals are subject to adjustment to reflect the impact of any acquisitions or dispositions that occur during the performance period. 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 sharesunits would be awarded.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 significantly 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. 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 20152016 Performance Stock Unit Awards.    The performance period for the 20152016 performance stock unit awards concluded on December 31, 2017.2018.

Mr. Trapp did not earn any shares as he terminated his employment prior to the end of the performance period for the 2016 performance stock unit awards.

        Restricted Stock Awards.    Restricted stock awards are shares of the Company's stock issued in the recipient's name but which are subject to forfeiture in the event the recipient's employment with the Company terminates prior to the time the shares vest. Upon vesting, the recipient owns the shares without restriction or risk of forfeiture. Recipients have voting and dividend rights with respect to restricted stock awards throughout the vesting period. The 20172018 restricted stock awards vest one-third each year over three years. In May 2018, after consulting with Mr. Pagano, the Compensation Committee awarded a special, one-time grant of restricted stock to Mr. Nanda to reward his strong performance managing both the Americas and Europe businesses and to provide a strong retention incentive. The special restricted stock award for Mr. Nanda had a value of $500,000 and will vest in its entirety on the fifth anniversary of the date of grant.

        CFO New Hire Grants.    In connection with Mr. Patel's commencement of employment with us as our Chief Financial Officer, we granted to Mr. Patel: (i) a restricted stock award valued at $700,000, which vests as to 50% on each of the first two anniversaries of his employment commencement date, (ii) a restricted stock award valued at $300,000, which vests in full on the third anniversary of his employment commencement date, (iii) a restricted stock award valued at $150,000 which vests as to one-third on each of the first three anniversaries of his employment commencement date, and (iv) a performance stock unit award valued at $150,000 at target, which vests at the end of 2020 based on the Company's performance relative to a set of goals with respect to revenue growth and return on invested capital that we consider challenging. These grants were intended to replace the value of unvested equity grants from Mr. Patel's prior employer that he forfeited in order to join us and were approved by the Compensation Committee following arms-length negotiations with Mr. Patel in connection with his hire.

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 of our full-time eligible employees who are United States residents.

        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. During 2017, we stopped providing our executive officers with the option to use a Company leased automobile in lieu of receiving a cash automobile allowance. We also reimburse our executives for certain financial planning expenses so they may focus more on their business responsibilities. We typically also reimburse recently hired executives for certain relocation-related expenses. In connection with Mr. Patel's commencement of employment with us, we agreed to pay customary out-of-pocket expenses incurred by him in connection with his relocation or, alternatively, to pay him a lump-sum cash payment of $50,000 to cover such 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.abroad, as described in more detail in the Summary Compensation Table below.

Compensation Recovery Policy

        We have a Compensation Recovery Policy, commonly referred to as a "claw back" policy, for our executive officers and chief accounting officer. Under this policy, in the event of a financial restatement due to fraudulent activity or intentional misconduct as determined solely by the Compensation Committee, our executive officers and chief accounting officer may be required to reimburse the Company for the difference between any incentive compensation (such as payments under the Executive Incentive Bonus Plan), equity awards or other compensation that was based on having met or exceeded Company performance targets that would not have been met based upon accurate financial data and the compensation that would have been granted, received, vested or accrued had such compensation been calculated based on the accurate data or restated results.

Employment Agreements

        None of our executive officers has an employment agreement with us.

        We have entered into indemnification agreements with each of our directors and executive officers. The indemnification agreements provide indemnity, including the advancement of expenses,

to our directors and executive officers against liabilities incurred in the performance of their duties to the fullest extent permitted by the General Corporation Law of the State of Delaware.

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 of 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 a change of control of the Company under the Executive Severance

Table of Contents

Plan. Further, we believe that providing these executive officers with severance benefits upon certain terminations following 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 were to cause the executive to be subject to the excise tax under Section 4999 of 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

Table of Contents

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, stock options and restricted stock units will become fully vested.

Stock Ownership Guidelines

        The Compensation Committee monitors compliance with the stock ownership guidelines approved by the Compensation Committee for all of our executive officers. For 2017,2018, 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 takes into account shares held directly, the shares underlying restricted stock units purchased by the executive under our Management Stock Purchase Plan and shares of restricted stock, but not stock options or performance share units. 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 2017,2018, all of our executive officers who had been executive officers of Watts for five or more years were in compliance with our stock ownership guidelines.

Impact of Regulatory Requirements

        The financial reporting and income tax consequences of individual compensation elements are important considerations for the Compensation Committee when it is analyzing the overall level of compensation and the mix of compensation paid to our executive officers. However, other factors may be of greater importance than preserving deductibility for a particular form of compensation. Overall, the Compensation Committee seeks to balance its objective of ensuring an effective compensation package for our executive officers with the desire to maximize the immediate deductibility of compensation, while ensuring an appropriate and transparent impact on reported earnings and other financial measures. The Compensation Committee 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 retains the discretion to payincome tax consequences of our executive compensation that is not tax deductible or could have adverse accounting consequences for the Company.programs.

        The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis included in this proxy statement with management. Based on such review and discussion with management, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement and in the Company's Annual Report on Form 10-K for the year ended December 31, 2017.2018.
