PROXY STATEMENT FOR 2023 ANNUAL MEETING 1

LETTER FROM OUR

BOARD OF DIRECTORS

DEAR FELLOW STOCKHOLDERS,

We are pleased to report that for the second consecutive year, the Company delivered double-digit net sales growth in Fiscal 2022. We once again increased our quarterly dividend by 5.5 percent and repurchased $35 million in common stock.

In partnership with the Board of Directors, the Company’s management team continued executing the strategic plan to drive innovation, operational improvements with our key capital projects and safety across the Company.

Aligned with our goal to become the leading provider of technology-enabled products for water utilities, we launched nine new products. These new products further strengthen Mueller’s position to help water utilities address the challenges they face from aging infrastructure, climate change, water scarcity and the labor market.

We expect to see benefits from our key capital projects with investments in our domestic manufacturing capabilities, primarily driven by the initial start-up of the new brass foundry in Decatur, Illinois, and completion of our plant restructuring consolidation into our Kimball, Tennessee facility. These investments improve our sustainability initiatives with a lead-free alloy that will be poured in our new brass foundry and increase efficiencies primarily driven by new equipment and the proximity to our new Kimball facility.

We published our second Environmental, Social and Governance (“ESG”) Report in January 2022, which outlined our ESG strategy, targets, performance and goals.

The Company’s Diversity, Equity and Inclusion efforts expanded during the year with the creation of our Diversity, Equity and Inclusion Council as well as local teams at every facility and another team for our corporate and sales teams.

Our Board of Directors believes in the importance of having best-in-class corporate governance. In October, we announced an accelerated board refreshment process as well as the appointment of two new board members. Brian Slobodow joined the Board in October, and Niclas Ytterdahl is serving as a Board observer until after the 2023 Annual Stockholders Meeting.

I would like to take a moment to recognize Bernard G. Rethore who, after 16 years of invaluable and distinguished service, will be retiring from the Board of Directors at the 2023 Annual Stockholders Meeting. Mr. Rethore has been a superb leader who has provided remarkable service and sound guidance during his tenure. He will be sincerely missed.

My fellow directors and I encourage you to review the accompanying Proxy Statement and associated materials prior to the Annual Meeting on February 7, 2023.

Thank you for being a Mueller Water Products stockholder and for your continued support.

MARK J. O'BRIEN

Non-Executive Chair of the Board

PROXY SUMMARY

This summary highlights information contained elsewhere in this Proxy Statement. This summary does not contain all of the information you should consider, and you should read the entire Proxy Statement carefully before voting.

Company Overview

The Mueller Water Products story began in 1857 when a young machine shop apprentice immigrated to America to establish his first business in Decatur, Illinois. In the 165 years since, the Mueller name has become known for innovative water distribution products of superior quality, many of which have become industry standards.

Although the business has undergone many changes throughout the years, our commitment to innovation has never wavered. We are proud of our position as a leading manufacturer and marketer of products and services used in the transmission, distribution and measurement of water in North America and of our broad product and service portfolio found worldwide, which includes engineered valves, fire hydrants, pipe connection and repair products, metering products, leak detection, pipe condition assessment, pressure management products and software technology that provides critical water system data.

This breadth of products and services enables us to deliver sustainable and efficient solutions that bridge the gap between intelligence and infrastructure, helping our customers deliver important water resources to their communities and empowering the smart cities of the future. We are one of the only companies that can fulfill the needs of water utilities from end to end – at the source, at the plant, below the ground, on the street and in the cloud. Built on a solid legacy of innovation, we have the expertise and vision to provide advanced infrastructure and technology solutions for transmitting, distributing, measuring and monitoring water more safely and effectively than ever before, demonstrating why Mueller Water Products is Where Intelligence Meets Infrastructure®. To learn more visit www.muellerwaterproducts.com.

Notable Achievements in Fiscal 2022

	We launched the Diversity, Equity and Inclusion Council.
	We increased corporate efficiencies and reduced our geographic and environmental footprint with the consolidation of our facilities in Woodland, Washington; Hammond, Indiana; Aurora, Illinois; and Surrey, British Columbia into the recently acquired facility in Kimball, Tennessee.
	We again increased our annual dividend, which is the seventh increase since 2014.
	We experienced the second consecutive year of double-digit net sales growth and ended the year with a record backlog.
	We published our second annual ESG Report, updating our ambitious goals and targets.

PROXY STATEMENT FOR 2023 ANNUAL MEETING 3

PROXY SUMMARY

Highlights of Fiscal 2022 Performance

	Focused on Operational Investment and Efficiencies to Increase Long-Term Stockholder Value
We generated net sales of $1,274.4 million, operating income of $111.6 million, adjusted earnings before interest tax depreciation and amortization (“EBITDA”) of $194.5 million and net income per diluted share of $0.48 (with adjusted net income per diluted share of $0.58). Adjusted EBITDA and adjusted net income are financial measures not calculated in accordance with generally accepted accounting principles in the U.S. (“GAAP”) and are therefore considered non-GAAP measures. See Exhibit A for a reconciliation of non-GAAP performance measures to GAAP performance measures.
	Dividend Benefits		Stockholder Value
•We paid stockholders a quarterly $0.058 per share dividend during fiscal 2022, an increase of 5.5% from fiscal 2021. •We returned $36.5 million to our stockholders through dividends in fiscal 2022.		We repurchased $35 million of our outstanding Common Stock during fiscal 2022.

Proposal One

Stockholder Engagement

With regular engagement with our stockholders, we are able to strengthen our relationships with stockholders and better understand stockholders’ views on our policies and practices and other matters of importance to our business. In 2022, management and the Board continued to reinforce our commitment to building long-term relationships with our stockholders. During the year, we utilized a variety of avenues for engagement including our Annual Meeting of Stockholders, in-person and virtual meetings, quarterly earnings calls and other investor events.

Fiscal 2022 engagement included: •Twelve investor events, including conferences, road shows and meetings •Topics of discussion included: •Drivers of sales growth including pricing initiatives, end market growth expectations and new product development •Health of key end markets, including municipal repair and replacement and new residential construction, and potential benefits from a federal infrastructure bill •Impacts of inflationary pressures, supply chain disruptions, manufacturing inefficiencies and labor availability •Environmental, Social and Governance topics, including strategies to achieve targets and goals •Capital spending plans, including three large capital projects •Cash flow expectations, including liquidity and working capital •Capital allocation strategy, including future capital spending and acquisitions, dividends and share repurchases •Our 2022 Annual Meeting of Stockholders We value the stockholder feedback that we receive through our engagement activities.

Sustainability

PRIORITY AND REPORTING

We view sustainability, including environmental, social and governance (“ESG”) practices, as essential to our long-term viability. As an industry leader for 165 years, we embrace our responsibilities for sustainability stewardship. We recognize that these responsibilities not only address our commitment to our employees and our facilities, but also extend to our other stakeholders, including our investors, customers, suppliers and communities.

Access to clean, safe water is essential. With the depletion of freshwater sources, the impacts of climate change and aging water infrastructure, we understand the importance of managing resources from start to finish. As a good steward and leader in water infrastructure, we embrace the opportunity and responsibility to make the world a better place for the benefit of future generations.

ELECTION OF DIRECTORS

Proposal One
Election of Ten Directors
	The Board recommends a vote FOR each nominee for director.

The Board of Directors

The Nominating and Corporate Governance Committee (the “Governance Committee”) is responsible for identifying qualified candidates to serve on the Board and recommending nominees to be submitted to our stockholders for election at each annual meeting. After the Governance Committee completes its evaluation of candidates, it presents its recommendation to the Board for consideration and approval.

We strive to maintain a diverse Board whose collective body of skills and experience supports achievement of the Company’s strategy. We work to balance industry expertise with independence and the institutional knowledge of longer-tenured directors with the fresh perspectives brought by new directors. The Governance Committee uses a matrix of key skills and experiences to evaluate candidates. The Governance Committee carefully reviews all directors and director candidates in light of these factors based on the context of the current and anticipated composition of the Board and our current and anticipated strategic and operating requirements. In reviewing a director candidate, the Governance Committee considers the following elements as qualifications required of all directors:

•Personal ethics and integrity •Independence •Collaborative skills •Interpersonal skills •Commitment •Business acumen

The Governance Committee expects and intends the Board to be comprised of directors with diverse backgrounds, skills and experiences. Although the Board does not have a formal policy regarding diversity, diversity is among the criteria considered by the Board when evaluating candidates. Diversity may include gender, race, ethnicity, geographic origin/foreign citizenship or personal, educational and professional experience. The Governance Committee further believes the backgrounds and qualifications of the directors, considered as a group, should provide an appropriate mix of experience, knowledge and abilities that will enhance the Board’s oversight role.

After sixteen years of distinguished service as a director on our Board, Bernard Rethore will retire from the Board at the 2023 Annual Meeting. Mr. Rethore has more than 30 years of experience at senior executive level positions with public manufacturing companies, including serving under various roles such as Chairman, President and Chief Executive Officer. Likewise, Mr. Rethore has shared his knowledge and experience with the boards of multiple public companies, as a member and chair of their executive, audit, compensation, environment, health and safety, governance and special committees. During his time with the Company, Mr. Rethore has served on multiple Board committees and as Chair of the Nominating and Corporate Governance Committee since 2015. His extensive management and board experience and broad perspective on matters involving business strategy, capital allocation, merger and acquisition opportunities and corporate governance have been instrumental in the Company’s success over the past sixteen years. We would like to take this opportunity to thank Mr. Rethore for his many years of service, oversight, guidance and dedication.

In connection with Mr. Rethore’s retirement, the Board will follow the recommendation of the Governance Committee and reduce the size of the Board from eleven to ten members upon Mr. Rethore’s retirement. See “Proposal One - Election of Ten Directors — The Board of Directors — Background to Solicitation” for information regarding additional Board activity.

PROXY STATEMENT FOR 2023 ANNUAL MEETING 25

ELECTION OF DIRECTORS

BACKGROUND TO SOLICITATION

General Information

As in recent years, we prioritized capital investments in fiscal 2022 and plan to continue such prioritization through fiscal 2023 to modernize our manufacturing facilities and processes. We believe this modernization will improve product quality, drive non-price margin expansion, reduce our geographic and environmental footprint and expand our product portfolio. Our large valve manufacturing expansion in Chattanooga, Tennessee neared full-scale production during fiscal 2022. We have completed the consolidation of multiple facilities into our new facility in Kimball, Tennessee to support machining and assembly capabilities in the Southeast. We anticipate that these investments and activities will enable us to capitalize on the growing need for large valves because of the migration to more densely populated, urban areas and an increased focus by customers on products made in America. In addition, we are nearing completion of our new brass foundry in Decatur, Illinois, scheduled to begin start-up production in 2023.

In fiscal 2022, we delivered our second consecutive year of double-digit net sales growth and ended the year with a record backlog. We also engaged in a program of regular Board refreshment that introduced three new directors since 2019. Board refreshment has been undertaken with attentiveness to continually enhancing the Board’s set of relevant skills and diversity of experience and successively strengthening the Board’s oversight capabilities.

Nominations and Settlement

On October 11, 2022, the Company entered into a cooperation agreement (the “Cooperation Agreement”) with Ancora Catalyst Institutional, LP and certain of its affiliates (collectively, “Ancora”), pursuant to which we agreed to appoint two new independent directors to the Board. Pursuant to the Cooperation Agreement, Brian Slobodow was appointed to the Board immediately and Niclas Ytterdahl is to be appointed to the Board within five business days of the 2023 Annual Meeting. Mr. Ytterdahl is serving as a board observer until he is appointed as a director. The Cooperation Agreement governs certain matters, such as the size of the Board and the composition of the Board’s committees and provided for the formation of the Capital Allocation and Operations Committee. Effective upon execution of the Cooperation Agreement, Ancora withdrew its notice of intent to nominate director candidates for election to the Board at the 2023 Annual Meeting.

A summary of the Cooperation Agreement is included in a Form 8-K filed with the U.S. Securities and Exchange Commission on October 13, 2022, with the full Cooperation Agreement filed as an exhibit to the Form 8-K.

The Board has always focused on maintaining a Board comprised of members with a diversity of backgrounds, skills, tenure, and expertise. As part of the Board’s continued refreshment plans and in conjunction with the Cooperation Agreement, the Company announced that it will accelerate the refreshment of the Board by adding several new directors with fresh perspectives in the near term. This plan is intended to further align the Board’s experience and skills with the Company’s strategic direction. As part of this plan, following the 2023 Annual Meeting, each member of the Board who has served for more than 10 years will depart during the next three years, with no more than three directors departing in any one year.

ELECTION OF DIRECTORS

Board Refreshment/Board Succession Planning

The Board believes that thoughtful refreshment is necessary to ensure that the Board remains aligned with the needs of the Company as it evolves. To that end, the Governance Committee regularly assesses director succession and board refreshment, with a focus on maintaining an optimal mix of institutional knowledge, industry expertise and fresh insight among its directors.

While the Board believes that tenure and age are important considerations in assessing Board composition, it also believes that the institutional knowledge and industry expertise contributed by its longer-tenured directors are of significant value to the Company and its current strategic direction. For this reason, the Board does not make membership decisions based solely on either metric.

Of equal importance is the varied perspective that new Board members bring. Four new directors have joined the Board since 2019 — their addition reflects the Board’s strong commitment to diversity across multiple dimensions including technical and financial skills, expertise and career background as well as personal traits such as age, gender and ethnicity. Additionally, an additional member is scheduled to join the Board in February 2023, which will bring the number of Board members with less than five years of tenure to five. See “Proposal One - Election of Ten Directors — The Board of Directors —Background to Solicitation” for information regarding planned Board refreshment activity.

Board Composition

The Board continues to identify and incorporate directors with diverse experiences and perspectives to provide the Company with thoughtful and engaged board oversight. In fiscal 2022, with Mr. Kolb’s retirement in February 2022, the number of Board members was ten. Each of our director nominees is independent, except Mr. Hall, our President and CEO. As demonstrated by the following key metrics(1), the Board actively seeks highly qualified women, individuals from underrepresented minorities and those with a wealth of diverse skills and talents to join the Board.

	9 of our 10 directors are independent, including the Chair		10 of our 10 directors have Executive Leadership/CEO experience
	3 of our 10 directors are women		4 of our 10 directors are from underrepresented minorities
	7 of our 10 directors have Corporate Governance experience

(1)In accordance with the Cooperation Agreement, Mr. Slobodow was appointed to the Board in October 2022. The fiscal 2022 metrics do not include or represent his appointment.

Director Nomination Process

In discharging its responsibility related to director nominations, the Governance Committee receives input from other directors and, if applicable, an independent professional search firm. It also considers and evaluates candidates recommended by stockholders, as described below. The Governance Committee utilizes the same process and criteria to evaluate all candidates. The Governance Committee’s comprehensive evaluation includes multiple stages. The Chair of the Governance Committee interviews each qualified candidate and selects candidates to be interviewed by other members of the Governance Committee. The Governance Committee's evaluation includes a reference and background check, as well as interviews and discussions about the candidate’s qualifications, availability and commitment. The Governance Committee reviews the results of all interviews and makes a recommendation to the full Board with respect to nominating a candidate for election to the Board. In evaluating candidates, the Governance Committee considers a variety of qualifications, experience, attributes and skills and recognizes that a diversity of knowledge, viewpoints and experience can enhance the Board’s effectiveness. Accordingly, as part of its evaluation, the Governance Committee considers how the candidate’s background, qualifications, experience, attributes and skills may enhance the quality of the Board’s deliberations and decisions.

ELECTION OF DIRECTORS

Set forth below is a summary of the key skills and experience necessary for the Board as a whole. See “Proposal One - Election of Ten Directors — The Board of Directors” for information concerning each nominee’s relevant skills and experience.

Skill/Experience	Relevance to Mueller Water Products
	Executive Leadership/CEO experience. Experience serving in top management positions is important since these directors bring perspective in analyzing, shaping and overseeing strategy and the execution of important operational and policy issues at a senior level.
	Corporate Governance expertise. Directors who have corporate governance experience can assist the Board in fulfilling its responsibilities related to the oversight of our legal, environmental and regulatory compliance.
	Financial/Capital Allocation expertise. Knowledge of financial markets, financing and funding operations, accounting and financial reporting processes is important since it assists our directors in understanding, advising and overseeing our capital structure, financing and investing activities, financial reporting and internal control of these activities.
	Government and Regulatory Affairs expertise. Directors who have served in government positions or who have worked extensively with governments, environmental or regulatory bodies can provide oversight of compliance with rules and regulations and insight into working constructively with government, environmental and regulatory bodies.
	International Business experience. Since we manufacture and sell certain of our products outside the United States, directors with global expertise can provide a useful business and cultural perspective regarding significant aspects of our businesses.
	Mergers and Acquisitions experience. Since we have a strategy of selectively pursuing potential acquisitions, directors who have a background in M&A transactions can provide useful insight into developing and implementing strategies for growing our businesses through combination with other organizations.
	Multiple-part Manufacturing and Operations experience. Experience in manufacturing is useful in understanding our research and development efforts, product engineering, design and manufacturing, operations, products and the market segments in which we compete.
	Strategic Planning expertise. We operate in competitive markets and our businesses are subject to a wide variety of risks. Directors who have strategic planning experience can assist the Board in adopting policies and procedures responsive to the risks we face.
	Enterprise Risk Management experience. In light of the potential financial and reputational damage that can occur when companies fail to oversee compliance and properly manage risk, it is increasingly important to include directors with extensive enterprise risk management experience.
	Human Capital Management experience. Because we recognize that an engaged and diverse workforce is the foundation of our success, it is important that our directors have experience with organizational management and talent development, including employee compensation and benefits, engagement and training, and diversity and inclusion.
	Environment, Health and Safety expertise. We are committed to responsible environmental stewardship and rigorous health and safety oversight. We believe directors with EHS experience can help drive strong environment, health and safety performance not only at the most strategic level but also throughout the organization.
	Technology experience. Directors with backgrounds in engineering disciplines, computer science, software development and cyber security are increasingly important in light of our strategic focus on manufacturing and product technologies.
	Materials Science and Engineering experience. Directors with a background in these areas are important to our understanding of how metals, nanomaterials and other substances meet the electrical, chemical or mechanical requirements of our products.
	Environmental, Social and Governance (“ESG”) experience. Directors with experience overseeing ESG strategy are important to ensure the Company successfully implements and executes the appropriate strategies for sustainability; diversity, equity and inclusion; and human capital management.
	Branding expertise. Directors who have worked to define and maintain perceptions of the nature and focus of an enterprise, specifically during transformative change, can be an invaluable asset.

ELECTION OF DIRECTORS

Director Candidate Recommendations

A stockholder who wishes to submit a director candidate for consideration by the Governance Committee must do so by writing our Corporate Secretary and including the candidate’s biographical data. See “Questions About Voting and the Annual Meeting.”

Board Tenure Policy

The Board believes that an appropriate mix of tenured directors and newer directors with fresh perspectives is necessary to ensure a vital and effective Board. Since January 2019, the Board has appointed four new directors, advancing both the skill set and experience profile of the Board while simultaneously increasing its diversity. Complementing this strategy of refreshment and enhancement is a commitment to making the most of our longer-tenured directors’ experience and intricate knowledge of the Company’s operations. While the Board believes that age and tenure are important considerations in assessing Board composition, it also believes the best interests of the Company are served by being able to take advantage of all available talent and that a significant degree of continuity year-over-year is beneficial to stockholders. For this reason, the Board does not have absolute limits regarding age of directors or the length of time that a director may serve but considers these aspects among several factors in re-nomination decisions.

The Board’s Role and Responsibilities

Overview

Our Board is responsible for overseeing the business affairs of the Company, including regularly monitoring the effectiveness of management’s implementation of strategy, policy, risk mitigation tactics and other decisions. As the Company continues to grow and transform, the Board not only guides management, but also assists in reacting to changing environments. The Board receives regular updates and engages actively with the management team regarding key strategic initiatives, technology trends, competitive and economic changes and other important developments and is also involved in strategic planning and review each year. Combined with management’s execution of our business strategy, the Board’s oversight promotes the creation of long-term stockholder value, with a focus on assessing both the potential opportunities available to us and the risks that we might encounter.

Board Oversight

RISK

While the Board maintains oversight responsibility for how we manage risk, it charges management with assessing and mitigating that risk through the development, implementation and maintenance of the Company's risk management processes and cyber security program. As a result, our internal control environment has been specifically designed to identify and manage risks and to facilitate communication with the Board. Our internal audit department, which reports to the Audit Committee, administers our enterprise risk assessment and, in coordination with our legal and compliance functions, is responsible for ongoing enterprise risk management processes. It also regularly reports to the Board and its committees on risk-related issues as a complement to our strategic planning process. Additionally, the Audit Committee consults with management regarding cyber security initiatives and requests that management report to the Audit Committee and/or the full Board regularly on its assessment not only of cyber security, but also of the operational, financial and accounting, competitive, reputational and legal risks to the Company. The Board also considers specific risk topics and receives regular reports from the heads of our principal businesses and corporate functions that include discussion of the risks and exposures inherent in their respective areas of responsibility.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE (“ESG”)

We embrace our ESG responsibilities and strive to effectively address the issues that matter most to our stockholders, employees, customers, suppliers, investors and the communities we serve. We are dedicated to transparency and measurement of our ESG performance as we execute our business strategy and expand our manufacturing reputation and expertise. We believe that a comprehensive ESG approach is more than a matter of process. Our ESG approach has been developed from a foundation of best practices and a desire for environmental, social and governance leadership, integrity and accountability.

Due to the significance of our ESG approach, the Board as a whole maintains oversight of the Company’s ESG program, including strategy, initiatives, metrics and policies. To facilitate its oversight, the Board has delegated certain responsibilities to its committees as follows:

•The Audit Committee oversees the appropriateness and reasonableness of the Company's applicable ESG standards, measurement mechanisms and key performance indicators.

•The Compensation and Human Resources Committee oversees matters related to human capital management, including matters relating to employee compensation, benefits, engagement, training, diversity, inclusion and other social matters.

•The Environment, Health and Safety Committee oversees the matters related to the environmental, materials sustainability and employee health and safety programs.

•The Nominating and Corporate Governance Committee reviews and makes recommendations to the Board regarding the Company’s ESG practices, reviews relevant ESG metrics developed by other Board committees and oversees management’s production of the Company’s ESG report.

The Company publishes an annual ESG Report, which includes the principal sustainability metrics the Company tracks: water withdrawal/energy consumption, greenhouse gas emissions and solid waste creation. The most current ESG Report may be found at https://www.muellerwaterproducts.com/sustainability-program-vision-and-values. The ESG Report is not a part of this Proxy Statement.

Management Succession Planning

Management conducts annual talent reviews. During these reviews, the executive leadership team discusses succession plans for key positions and identifies top talent for development needed in future leadership roles. The Board maintains a succession and contingency plan for the CEO position as well as other key officer positions.

Corporate Governance Policies and Materials

Our Code of Business Conduct and Ethics (the “Code of Conduct”) applies to all of our employees and directors. We also make available an ethics helpline that employees and others may use to anonymously report suspected violations of the Code of Conduct. We will disclose promptly any amendments to, or waivers from, provisions of the Code of Conduct on our website at www.muellerwaterproducts.com, as may be required under applicable rules.

Stockholder Engagement

We believe that strong corporate governance should include regular engagement with our stockholders to enable us to understand and respond to stockholder concerns. Understanding the issues important to our stockholders is critical to ensuring that we address their concerns in a meaningful and effective way. In 2022, management and the Board, as appropriate, continued to reinforce our commitment to building long-term relationships with our stockholders. As part of our engagement program, we visit representatives of many of our top institutional stockholders to solicit feedback on performance, strategy, vision, risk management and other matters. We strive to be responsive to our stockholders and are committed to continued engagement.

Board Structure

Board Leadership Structure

Our governance documents provide the Board with the flexibility to select the appropriate leadership structure for the Company, and the Board believes separating the roles of Chair and Chief Executive Officer is in the best interest of the Company and its stockholders. Mr. O’Brien serves as our Non-Executive Chair, and Mr. Hall serves as our President and Chief Executive Officer.

Under our Bylaws, the Chair presides over meetings of the Board and of stockholders, while the Chief Executive Officer has general and active management of our property, business and affairs, subject to the supervision and oversight of the Board.

The Board believes this structure facilitates decisive and effective leadership and, when combined with our other governance policies and procedures, provides appropriate opportunities for oversight, discussion and evaluation of decisions and direction by the Board.

Director Independence

The Governance Committee and the Board annually assess the outside affiliations of each director to determine if these affiliations could cause a potential conflict of interest or interfere with the director’s independence. Our Corporate Governance Guidelines (the “Guidelines”) set forth the categorical standards of independence for the Board. To be considered “independent” for purposes of the director qualification standards:

•The director must meet bright-line independence standards under NYSE listing standards; and

•The Board must affirmatively determine the director otherwise has no material relationship with us directly or as an officer, stockholder or partner of an organization that has a relationship with us. See the Guidelines on our website www.muellerwaterproducts.com for more detail.

Each of our directors, other than our President and CEO, is independent pursuant to our director qualification standards and each member of the Audit Committee, the Compensation and Human Resources Committee (the “Compensation Committee”) and the Governance Committee is independent in accordance with NYSE listing standards.

•No member of those committees receives compensation from us other than directors’ fees and no member is an affiliated person of ours (other than by virtue of his or her directorship).

•Members of the Audit Committee meet the additional standards for audit committee members of publicly traded companies required by the Sarbanes-Oxley Act of 2002.

•All members of the Compensation Committee qualify as “non-employee directors” as defined in Rule 16b-3 under the Exchange Act and meet the independence requirements of NYSE listing standards and additional standards applicable to “outside directors” under Section 162(m) of the Internal Revenue Code.

ELECTION OF DIRECTORS

Executive Sessions

Our non-employee directors meet at least quarterly in executive sessions at which only non-employee directors are present. Our Non-Executive Chair presides at these sessions.

Board Committee Information

The Board currently has five standing committees: the Audit Committee, the Capital Allocation and Operations Committee (“Capital Allocation Committee”), the Compensation Committee, the Governance Committee and the Environment, Health and Safety Committee (“EHS Committee”). An additional committee, the Executive Committee, meets only as needed. Each member of the Audit, Compensation, Governance and EHS Committees satisfies both the NYSE’s and our definitions of an independent director, and the Board has determined that all Audit Committee members are “financially literate” and at least one independent member qualifies as an “audit committee financial expert” under the NYSE listing standards and the rules and regulations of the SEC. The Board designated Mr. Van Arsdell as an “Audit Committee financial expert” during 2022.

Each standing committee meets periodically throughout the year, reports its actions and recommendations to the Board, receives reports from management and annually evaluates its performance. Additional information about the committees is provided below. In addition to being a member of the Capital Allocation Committee and the Executive Committee, Mr. O'Brien is an ex officio member of the other standing committees.

Board Practices, Processes and Policies

History of Commitment to Good Governance Practices

The Board has always followed a principled framework in carrying out its oversight responsibilities related to the business of the Company. The Board is committed to good corporate governance practices and a sound governance structure that promote the interests of all stockholders. While the underlying guiding principles of the Board remain consistent, the implementation of these principles continues to be flexible and evolves in response to ever-changing business, legal and social environments.

Director Attendance

The Board held 8 meetings in fiscal 2022 and each director attended at least 93% of the total number of meetings of the Board and its committees of which she or he was a member in fiscal 2022. Although the Company does not have a formal policy requiring attendance at annual meetings, directors are encouraged to attend, and each then-current director also attended the 2022 Annual Meeting of Stockholders.

Fiscal 2022 Board/Committee meeting attendance

Director, Board and Committee Evaluations

Each year, the Guidelines require the Board to conduct an evaluation of its own performance. Additionally, our committee charters require each of our committees to conduct an annual performance evaluation. The Governance Committee is responsible for overseeing the annual assessment process on behalf of the Board and its committees. Throughout the evaluation process, the Governance Committee solicits comments from directors, via self and peer evaluations and committee and Board assessments, to ensure that the Board as a whole, its committees and each director are functioning effectively. The Governance Committee reviews comments from each director to assess directors’ contributions to the Board, evaluates the Board’s contributions to the Company and identifies areas for improvement in the Board’s performance. The Governance Committee discusses its findings with the Board annually regarding ways in which the Board and its committees can improve their key functions.

Director Orientation and Continuing Education

The Company’s Guidelines establish recommendations for director onboarding and continued education. All new members of the Board participate in the Company’s new director orientation program, including corporate document and policy reviews, management meetings and site visits. Additionally, directors participate in an in-depth review of the Company strategy and have the opportunity to meet with senior management and obtain insights into the business. All directors are encouraged to participate in continuing education programs, with any associated expenses reimbursed by the Company, to stay current and knowledgeable about the Company’s industry, market and overall environment. Such orientation and continuing education programs are overseen by the Governance Committee.

ELECTION OF DIRECTORS

Corporate Governance Guidelines

Our Board is committed to establishing and maintaining strong corporate governance practices that reflect high standards of ethics and integrity and promote long-term stockholder value.

To that end, our Bylaws provide that our directors must be elected by the affirmative vote of a majority of the votes cast at the Annual Meeting. Additionally, the Guidelines provide that an incumbent director who fails to receive a majority of the votes cast must tender an irrevocable offer of resignation to the Board. The Board will then consider a number of factors in determining whether to accept or reject the resignation, including the director’s contributions to the Company.

Our corporate governance structure and processes are set forth in our key governance documents, including the Guidelines. The Guidelines govern the operation of the Board and its committees and guide the Board and its committees in the execution of their respective responsibilities. The Governance Committee reviews the Guidelines at least annually, and the Board updates the Guidelines periodically in response to changing regulatory requirements, evolving practices and otherwise as circumstances warrant.

An important aspect of achieving a strong and effective corporate governance structure is to encourage an open dialogue with our stockholders. Accordingly, highlighted below are the key areas of our corporate governance practices that we believe align with common best practices.

Board Composition and Leadership	ü	Our Board is led by an independent Non-Executive Chair who is not our CEO
	ü	Each of our director nominees, other than our President and CEO, is independent
	ü	Our directors have complementary and diverse skills sets, backgrounds and experiences and are continually educated on our industry
	ü	Our Board size promotes an open dialogue among directors
Director Elections	ü	We use a majority voting standard in uncontested director elections, and require incumbent directors who fail to receive a majority of the votes cast to tender their resignation
	ü	Directors are elected on an annual basis
Board Committee Structure	ü	We have a well-developed committee structure with clearly understood responsibilities
	ü	With the exception of the newly created Capital Allocation and Operations Committee in accordance with the Cooperation Agreement, each member of our standing committees is independent
Director Effectiveness	ü	Our Board, committees and directors conduct regular self and peer evaluations, led by our Governance Committee, to assess effectiveness and areas for improvement
Director Responsibilities	ü	Each of our directors has input into the setting of the Board agenda
	ü	Each of our directors has unfettered access to management, and committees have the authority to retain independent advisors
	ü	Our Board frequently meets in executive session without the CEO or other members of management
	ü	Our Board focuses on significant risks and seeks the proper calibration of risk and reward while focusing on the longer-term interests of our stockholders
Director Compensation	ü	We pay a substantial portion of non-employee director compensation in equity grants

Related Person Transactions

The Governance Committee administers a written Related Person Transaction Policy that applies to any transaction or series of transactions in which we are a participant, the amount involved exceeds or may be expected to exceed $120,000 and a related person has a direct or indirect material interest. Under the policy, our Chief Legal and Compliance Officer determines whether a transaction meets the requirements of a related person transaction requiring review by the Governance Committee. Transactions that fall within this definition will be referred to the Governance Committee for approval, ratification or other action. Based on its consideration of all of the relevant facts and circumstances, the Governance Committee will decide whether or not to approve the transaction and will approve only those transactions that are in our best interest. In addition, the Board has delegated to the Chair of the Governance Committee the authority to

36 MUELLER WATER PRODUCTS, INC.

ELECTION OF DIRECTORS

pre-approve or ratify any transaction with a related person in which the aggregate amount involved is expected to be less than $500,000.

We did not engage in any transaction during fiscal 2022, and have no currently proposed transaction, in which the amount involved exceeds $120,000 and a related person had or will have a direct or indirect material interest.

Communicating with the Board

Stockholders and other interested parties may communicate with any of our directors, including our Non-Executive Chair and the Chairs of our committees, or our independent directors as a group, on Board-related issues by writing in care of our Corporate Secretary at our principal executive office address: 1200 Abernathy Road, N.E., Suite 1200, Atlanta, Georgia 30328. Stockholders and other interested persons may also communicate with directors by sending an email message to boardofdirectors@muellerwp.com, or with the Audit Committee by sending an email message to auditcommittee@muellerwp.com. These procedures may change from time to time. Please visit our website at www.muellerwaterproducts.com for the most current means of contacting our directors.

Director Compensation

The Compensation Committee is responsible for reviewing and considering revisions to director compensation. With the assistance of its independent compensation consultant, the Compensation Committee reviews director compensation and compares it to director compensation paid by other companies in the peer group described under “Compensation Discussion and Analysis — Executive Compensation Program Overview — Peer Group Benchmarking and Total Compensation.”

The Board reviews the Compensation Committee’s recommendations and determines the final structure and amounts of director compensation. The Board has determined compensation for non-employee directors should comprise a mix of cash and equity-based awards consistent with the mix and form of payment implemented by other companies in our peer group. In addition to utilizing an overall compensation structure consistent with market practice, the Board believes the interests of directors are aligned with the interests of other stockholders by linking a significant portion of director compensation to Common Stock performance. Under our stock ownership guidelines, directors are required to hold at least 50% of the Common Stock acquired through equity-based awards until they own Common Stock equal in market value to at least five times their annual retainer. See “Compensation Discussion and Analysis — Other Compensation Practices and Policies — Stock Ownership Guidelines” for more information.

Annual Retainer

Each non-employee director was entitled to receive an annual retainer of $65,000 for fiscal 2022. In addition, the Chairs of the Audit Committee, the Compensation Committee, the Governance Committee and the EHS Committee were entitled to receive chair fees equal to $20,000, $15,000, $10,000 and $10,000, respectively. Our Non-Executive Chair receives $100,000 for serving in this capacity. The annual retainers and chair fees are paid quarterly.

Meeting Fees

Each non-employee director was entitled to receive $1,500 for each Board or committee (in which the applicable director was a member) meeting attended during fiscal 2022, except that our Non-Executive Chair, who is an ex officio member of the Audit, Compensation, Governance and EHS Committees of the Board, receives no fees for meetings of these Committees. Meeting fees are paid promptly after the conclusion of each meeting.

Deferred Compensation

The Board adopted the Mueller Water Products, Inc. Directors’ Deferred Fee Plan, as amended, under which non-employee directors may elect to defer all or a portion of their directors’ fees. We make deferred payments in January of the year determined by the non-employee director pursuant to an election filed with our Corporate Secretary. The payments may be made in any calendar year not earlier than the year in which the participant has his or her 72nd birthday or the year of the participant’s termination of his or her services as a director, with the payment made in cash in one, five, ten or fifteen annual installments as determined by the participating director in his or her election form. Mr. Tokarz was the only non-employee director who participated in this plan during fiscal 2022. Mr. Tokarz’s deferred payments are maintained in a stock equivalent account.

ELECTION OF DIRECTORS

Equity-Based Awards

Our Second Amended and Restated 2006 Stock Incentive Plan (the “Stock Plan”) provides that, on the date of each annual meeting of stockholders, we will grant equity-based awards with an economic value determined by the Compensation Committee to each non-employee director who is re-elected to the Board and has served as a director for at least six months. In addition, the Stock Plan provides that each director will receive an initial equity-based grant on the date on which he or she commences service as a director, the economic value and terms of which will be determined by the Compensation Committee. See “Compensation Discussion and Analysis — Other Compensation Practices and Policies — Role of Compensation Consultant in Compensation Decisions.”

On February 7, 2022, each non-employee director received equity-based awards in the amount of $115,000, which resulted in the grant of 8,825 restricted stock units (“RSUs”) in accordance with the Stock Plan and related policies. These RSUs will vest for directors remaining in continuous service through the first anniversary of the grant date, although the Compensation Committee may waive this minimum service requirement. On February 7, 2022, in connection with his retirement from service, Mr. Kolb received an equity-based award in the amount of $115,000, which resulted in the grant of 8,825 RSUs that vest one half per year on each of the first two anniversary dates of the grant date.

Travel Expenses

We reimburse directors for their travel and related expenses in connection with attending Board and committee meetings and related activities.

PROXY STATEMENT FOR 2023 ANNUAL MEETING 39

EXECUTIVE COMPENSATION

Proposal Two
Advisory Vote to Approve Executive Compensation
	The Board recommends a vote FOR this proposal.

We provide our stockholders with the annual opportunity to cast an advisory vote to approve the compensation of our named executive officers. The vote on this proposal represents an additional means by which we obtain feedback from our stockholders about executive compensation. Our Compensation Committee sets executive compensation.

The overall objective of our executive compensation program is to encourage and reward the creation of sustainable, long-term stockholder value. To meet this objective, the Compensation Committee has designed compensation plans for our executive officers that target total compensation at or about the regressed 50th percentile of our customized peer group. See “Compensation Discussion and Analysis — Executive Compensation Program Overview — Peer Group Benchmarking and Total Compensation.” A significant portion of our executives’ overall compensation is structured as incentive compensation. For fiscal 2022, incentive compensation represented approximately 83% of our current CEO’s total target compensation (excluding Other Compensation), and an average of 67% of the total target compensation (excluding Other Compensation) of the other named executive officers. We believe an emphasis on both short-term and long-term incentive compensation aligns executives’ and stockholders’ interests. Further, the Company’s results, as measured against the performance metrics established by the Committee in fiscal 2022, produced a performance-based cash incentive compensation payout percentage of 89.3% of target for Ms. Zakas and Messrs. Hall, Heinrichs and Helms and 91.0% of target for Mr. Takeuchi and a long-term incentive payout percentage of 70.0% for incentives based on RONA performance and 88.9% for incentives based on relative total shareholder return for all NEOs, which illustrate rigorous and meaningful targets and highlight the Committee's pay-for-performance philosophy.

We encourage our stockholders to read the Compensation Discussion and Analysis section of this Proxy Statement, which discusses how our compensation policies and procedures implement our compensation philosophy. The Board and the Compensation Committee believe these policies and procedures are strongly aligned with the long-term interests of our stockholders and are effective in implementing our compensation philosophy and in achieving our strategic goals.

Accordingly, we ask for stockholder approval of the following resolution:

RESOLVED, that the stockholders of Mueller Water Products, Inc. approve, on an advisory basis, the compensation paid to the Company’s named executive officers, as disclosed in the Compensation Discussion and Analysis, the accompanying compensation tables and the related narrative disclosure in the Company’s proxy statement for the 2023 annual meeting of stockholders.

At the most recent annual meeting of stockholders, approximately 93% of votes cast were in support of the compensation of our named executive officers. The Compensation Committee will once again consider the result of this year’s vote, as well as other communications from stockholders relating to our compensation practices, and take them into account in future determinations concerning our executive compensation program. See “Compensation Discussion and Analysis — Highlights of 2022 Executive Compensation.”

Compensation Committee Interlocks and Insider Participation

During fiscal 2022, none of the members of the Compensation Committee (comprised of Shirley C. Franklin, Thomas J. Hansen, Jeffery S. Sharritts, Michael T. Tokarz and Stephen C. Van Arsdell) was a former or current officer or employee of the Company or any of its subsidiaries or had any relationships requiring disclosure as a related person transaction.

Compensation Discussion and Analysis

This Compensation Discussion and Analysis is intended to provide our stockholders with information about our fiscal 2022 compensation program for the following executive officers (collectively, “named executive officers” or “NEOs”):

J. Scott Hall President and Chief Executive Officer	Marietta Edmunds Zakas Executive Vice President and Chief Financial Officer	Steven S. Heinrichs Executive Vice President, Chief Legal and Compliance Officer and Secretary	Todd P. Helms Senior Vice President and Chief Human Resources Officer	Kenji Takeuchi Senior Vice President, Water Management Solutions

Notable Achievements in Fiscal 2022

	We continued execution of our long-term capital allocation strategy, allocating approximately $55 million for capital expenditures, nearing completion of the new lead-free brass foundry and reducing our geographic footprint.
	We launched the Diversity, Equity and Inclusion Council.
	We increased corporate efficiencies and reduced our geographic and environmental footprint with the consolidation of our facilities in Woodland, Washington; Hammond, Indiana; Aurora, Illinois; and Surrey, British Columbia into the recently acquired facility in Kimball, Tennessee.
	We again increased our annual dividend, which is the seventh increase since 2014.
	We experienced the second consecutive year of double-digit net sales growth and ended the year with a record backlog.
	We published our second annual ESG Report, updating our ambitious goals and targets.

Highlights of Fiscal 2022 Performance

	Focused on Operational Investment and Efficiencies to Increase Long-Term Stockholder Value
We generated net sales of $1,274.4 million, operating income of $111.6 million, adjusted EBITDA of $194.5 million and net income per diluted share of $0.48 (with adjusted net income per diluted share of $0.58). Adjusted EBITDA and adjusted net income are financial measures not calculated in accordance with GAAP and are therefore considered non-GAAP measures. See Exhibit A for a reconciliation of non-GAAP performance measures to GAAP performance measures.
	Dividend Benefits		Stockholder Value
•We paid stockholders a quarterly $0.058 per share dividend during fiscal 2022, an increase of 5.5% from fiscal 2021. •We returned $36.5 million to our stockholders through dividends in fiscal 2022.		We repurchased $35 million of our outstanding Common Stock during fiscal 2022.

Highlights of 2022 Performance Related to Executive Compensation

The Compensation Committee used several financial and performance elements (including those set forth below) to assess and determine incentive plan compensation earned during fiscal 2022. Our compensation programs continually evolve to incorporate stockholder feedback, market best practices, and performance and retention considerations. Our stockholders have strongly supported our executive compensation program in the past, as exhibited by an affirmative “say-on-pay” vote of approximately 95% and 93% in each of the last two years. See Exhibit A for a reconciliation of the following non-GAAP financial measures used in determining executive compensation to GAAP financial results.

Company Results for Performance Evaluation Basis
	Company-Wide			Segment Performance (Water Management Solutions)		Return on Net Assets(3) (RONA)	Relative Total Shareholder Return(4) (rTSR)
	Net Sales	Adjusted EBITDA(1)	Adjusted Working Capital (as a % of Net Sales(2)	Net Sales	Adjusted EBITDA(1)
	($ in millions)		%	($ in millions)		%	Percentile
2022	1,247.4	195.2	27.5	516.0	115.6	19.6	44.4

(1)Defined for this purpose as net income plus interest, income tax, depreciation and amortization expenses, adjusted to exclude significant unusual charges and credits. For the purposes of Adjusted EBITDA for performance evaluation basis, the Company removed the amounts related to Workplace Safety Assessment costs.

(2)Adjusted Working Capital as a Percent of Net Sales is a non-GAAP measure and means the Average Net Working Capital over the previous five calendar quarters divided by Net Sales for the fiscal year, subject to certain applicable adjustments. ‘‘Average Net Working Capital’’ means, as of September 30, 2022, the average of the last five quarter end balances for each of (i) receivables, as reported, plus (ii) inventories, as reported, minus (iii) accounts payable. For fiscal 2022, there were no adjustments to the working capital as a percent of net sales.

(3)Defined for this purpose as the after-tax quotient obtained by dividing performance evaluation basis adjusted operating income plus amortization of capitalized software and intangible assets by the quarterly average of the sum of working capital, excluding cash, current debt and accrued interest and other items plus property, plant and equipment.

(4)See “Proposal Two - Advisory Vote to Approve Executive Compensation — Compensation Discussion and Analysis — Long-Term Equity-Based Compensation” for more information on rTSR.

Highlights of 2022 Executive Compensation

We design our executive officer compensation programs to target total compensation at or about the regressed 50th percentile for comparable executive positions at companies in our peer group. The principal elements of our compensation program for executives are base salary, annual performance-based cash bonus, long-term incentive equity compensation and broad-based benefit programs and executive severance plan, as applicable.

We tie our executives' compensation to Company performance.

For fiscal 2022, 56.0% of our CEO’s total target compensation, and an average of 47.8% of the total target compensation of our other NEOs, could only be earned by meeting performance goals.	PERFORMANCE-BASED TOTAL TARGET COMPENSATION(1)

(1)Excludes Other Compensation. See "Executive Compensation — Summary Compensation Table" for total compensation as earned.

•Our NEOs’ compensation was both negatively and positively affected by Company performance in relation to targets set for fiscal 2022.

•Annual cash bonuses earned by our NEOs (excluding Mr. Hall) for fiscal 2022 ranged from $168,359 to $280,528 compared with $234,925 to $443,070 last year.

•Long-term performance-based compensation based on the RONA financial measure was paid or credited at 70.0% of target and long-term performance-based compensation based upon rTSR was paid or credited at 88.9% of target for fiscal 2022.

We structure performance-based compensation to pay for performance.

We set clear and measurable financial goals for Company performance. In evaluating individual performance, we assess progress toward strategic priorities.

We consider stockholder feedback on executive compensation.

At our 2021 and 2022 annual meetings of stockholders, approximately 95% and 93%, respectively, of the votes cast supported the advisory vote on executive compensation. We carefully consider feedback from our stockholders regarding executive compensation.	“SAY-ON-PAY” SUPPORT

EXECUTIVE COMPENSATION

Executive Compensation Program Overview

Guiding Principles

The Compensation Committee has identified the following guiding principles in overseeing the compensation program for our executives:

Competitiveness Compensation programs should be designed to target at the regressed 50th percentile of total compensation for comparable executive positions at a customized peer group.	Pay for Performance Where compensation for an executive is tied to the achievement of financial and strategic goals, actual results that exceed target levels should provide above-target payouts, and results that do not exceed threshold levels should not provide payouts.
Responsibility A significant portion of an executive’s overall compensation should be tied to the achievement of financial performance goals. The portion of an executive’s target total compensation that is incentive based should increase as an executive’s responsibilities increase.	Stockholder Alignment Executives’ interests are more directly aligned with stockholders’ interests when compensation programs: •Emphasize both short- and long-term financial performance; •Are significantly impacted by the value of Common Stock; and •Require meaningful Common Stock ownership.

Peer Group Benchmarking and Total Compensation

Each year, the Compensation Committee’s compensation consultant collects peer group compensation data and prepares an executive benchmarking study using a market regression analysis to size-adjust the market data for our net sales size as a whole. The Compensation Committee, with input from its independent compensation consultant, reviews the prior year peer group. This review focuses on companies that have a primary manufacturing component to their businesses, have similar organizational structures and are publicly traded or otherwise file financial statements with the SEC. We believe the resulting peer group provides a valid and appropriate comparison for the Company’s executive compensation program and governance practices. For fiscal 2022, the Compensation Committee did not make any changes to the previous year’s group. The peer group for fiscal 2022 (“Peer Group”) consisted of the companies listed below.

Fiscal 2022 Peer Group		The Compensation Committee targets total compensation at or about the regressed 50th percentile of the Peer Group
Armstrong World Industries, Inc.	Helios Technologies, Inc.

The Compensation Committee regularly reviews the target total compensation of each executive and compares it to the total compensation for comparable executive positions in the Peer Group. The Compensation Committee targets total compensation at or about the regressed 50th percentile of the Peer Group, subject to individual adjustments based on experience, length of service, individual performance and other factors deemed appropriate by the Compensation Committee.

Salary

The Compensation Committee regularly compares the salary of each executive to the regressed 50th percentile of comparable executives in the Peer Group and uses that benchmark as a guide. Salaries for the NEOs are adjusted, as appropriate, annually on February 1. The Compensation Committee approved the following salaries for our NEOs in fiscal 2022.

Name	Annual Salary Rate at September 30, 2022 ($)	Annual Salary Rate at September 30, 2021 ($)	Salary Increase (%)
J. Scott Hall	854,000	825,000	3.5

Annual Cash Incentive Awards

The annual cash incentive plan rewards our named executive officers for achieving key financial metrics, which drive our operating results and enhance stockholder value. The Compensation Committee targets annual cash incentive compensation for each executive at the regressed 50th percentile of comparable executives in the Peer Group. Based on actual achieved performance against performance goals, each NEO may earn between 0% and 200% of his or her annual cash target opportunity. For fiscal 2022, the Compensation Committee selected two types of performance metrics: (i) financial goals (weighted 90%) and (ii) EHS-related performance metrics (weighted 10%). The financial goals related to

PROXY STATEMENT FOR 2023 ANNUAL MEETING 45

EXECUTIVE COMPENSATION

adjusted EBITDA, adjusted working capital (as a % of net sales) and net sales. The Compensation Committee selected these financial metrics to encourage our NEOs to focus on generating income from continuing operations and enhancing long-term stockholder value. The EHS-related performance metric was tied to reductions in total recordable incidence rates and key performance indicators for sustainability and specific activities identified as leading safety indicators. The Compensation Committee selected these metrics because they promote, drive and support the Company’s EHS initiatives and performance. All financial performance goals were set with minimum (or threshold), target and maximum objectives for each goal as described in the “Performance Targets and Results” table below.

Long-Term Equity-Based Compensation

The long-term incentive program aligns the interests of our NEOs with those of our stockholders and rewards our NEOs for achieving key metrics. This program drives operating results, enhances stockholder value and helps retain our NEOs. Due to the rules for how the grant date fair value of long-term incentive awards must be calculated for accounting purposes, the 2022 Summary Compensation Table may not reflect the same stock option and PRSU values described below. In addition, accounting values can increase or decrease each year, causing volatility in the long-term incentive awards reported. For fiscal 2020 through fiscal 2022, the Compensation Committee set each NEO’s target long-term compensation value at or about the regressed 50th percentile of comparable executives in the Peer Group.

For fiscal 2022 and fiscal 2021, the NEOs’ target long-term compensation value was allocated 50% in the form of performance-based restricted stock units (“PRSUs”), 25% in the form of time-based stock options and 25% in the form of time-based restricted stock units (“RSUs”). The fiscal 2022 and fiscal 2021 PRSUs are based solely upon rTSR performance ("Market Units").

For fiscal 2020, the NEOs’ target long-term compensation value was allocated 70% in the form of PRSUs and 30% in the form of RSUs. Fiscal 2020 PRSUs were divided into two categories, based upon applicable performance metric: (i) 57% of the PRSUs (and 40% of the total award) are based upon after-tax RONA achievement ("RONA Units") and (ii) 43% of the PRSUs (and 30% of the total award) are based solely upon rTSR performance, i.e., Market Units.

PERFORMANCE-BASED RESTRICTED STOCK UNITS

The following are the key aspects of the PRSUs awarded, granted, earned and/or vested in fiscal 2022 and fiscal 2021:

PRSUs Awarded for Fiscal 2022 and Fiscal 2021:

•For fiscal 2022 and fiscal 2021, 50% of each NEO’s target long-term incentive compensation value was awarded in PRSUs. The number of PRSUs awarded in fiscal 2022 and fiscal 2021 was equal to the target value divided by the share price of our Common Stock on the date of award.

•The fiscal 2022 and fiscal 2021 PRSUs are based solely upon the Company’s rTSR performance, i.e., Market Units.

•Market Units:

◦The relative total shareholder return or “rTSR” is measured by, during the applicable performance period, computing the total shareholder return of each company that was in the S&P 600 SmallCap Industrial Index at the beginning of the applicable performance period (the “TSR Group”) and comparing the Company’s total shareholder return results thereto in order to determine the quartile ranking within the TSR Group.

◦The Market Units consist of a single tranche and vest on a 3-year cumulative performance period against the applicable index.

◦The Compensation Committee establishes the performance period target related to the Market Unit award on the grant date of the award.

◦At the end of the three-year award period, the Compensation Committee confirms actual performance against the applicable performance target.

◦The number of shares of our Common Stock earned at the conclusion of each Market Unit performance period may range from zero to two times the number of target Market Units awarded, based on the level of achievement against the applicable performance period target.

PRSUs Awarded for Fiscal 2020:

•For fiscal 2020, 70% of each NEO’s target long-term incentive compensation value was awarded in PRSUs. The number of PRSUs awarded in fiscal 2020 was equal to the target value divided by the share price of our Common Stock on the date of award. As noted above, the fiscal 2020 PRSUs comprise RONA Units and Market Units.

•Market Units: Market Unit details are described above for fiscal 2021 and fiscal 2022.

• RONA Units:

◦RONA Units are divided into three equal tranches and each tranche is measured and earned over successive one-year performance periods coinciding with our fiscal years.

PROXY STATEMENT FOR 2023 ANNUAL MEETING 47

EXECUTIVE COMPENSATION

◦The Compensation Committee establishes RONA Unit performance period targets for the then-current performance period on an annual basis.

◦At the end of each performance period, the Compensation Committee confirms actual performance against the applicable performance period target.

◦The number of shares of our Common Stock earned at the conclusion of each applicable RONA Unit performance period may range from zero to two times the number of target RONA Units in the applicable tranche, based on the level of achievement against the applicable performance period target.

◦RONA Units representing the level of achievement during the specific performance period are “banked” for potential payout following the end of the three-year award cycle.

PRSUs Generally:

•All PRSUs are settled in shares of Common Stock.

•To receive earned shares of Common Stock, the NEO must be employed through the last day of the three-year award cycle.

•PRSUs do not convey voting rights or accrue dividends until vested.

PERFORMANCE MEASURE AND RESULT FOR FISCAL 2022

The applicable performance target for the fiscal 2022 performance period for PRSUs awarded in fiscal 2020 was based partially on RONA and partially on rTSR. The applicable performance targets for the fiscal 2021 and fiscal 2022 performance periods for PRSU awards made in fiscal 2021 and fiscal 2022, respectively, were based solely on rTSR. No RONA Units were awarded in fiscal 2021 or fiscal 2022. “RONA” has the meaning described in footnote 4 to the table under “— Highlights of 2022 Performance Related to Executive Compensation.”

The Compensation Committee determined the RONA target using benchmark data from the Peer Group and assistance from the Company’s independent compensation consultant. For fiscal 2020, fiscal 2021 and fiscal 2022, the Compensation Committee established the RONA target at an absolute percentage on an after-tax basis. For fiscal 2022, the performance necessary to earn at least 50% of RONA Unit target payout required RONA of 18.0%, the performance necessary to earn 100% of RONA Unit target payout required RONA of 22.0%, and the performance necessary to earn the maximum 200% of RONA Unit target payout required RONA of at least 23.6%. Actual RONA performance for fiscal 2022 was 19.6%. Therefore, the 2022 performance period RONA Units will settle at 70.0% of the awards. See “Executive Compensation — Grants of Plan-Based Awards Table.”

The Compensation Committee determined the rTSR target using benchmark data from the S&P 600 SmallCap Industrial Index (based upon a 20 trading day average) and assistance from the Company’s independent compensation consultant. For fiscal 2020, fiscal 2021 and fiscal 2022 grants, the performance necessary to earn 100% of Market Unit target payout requires the rTSR to be in the 50th percentile, and the performance necessary to earn the minimum of 50% and a maximum of 200% of Market Unit target payout requires the rTSR to be in the 25th and 75th percentile, respectively. The fiscal 2020, fiscal 2021 and fiscal 2022 Market Unit grants vest and settle at the end of the corresponding cumulative 3-year performance period. For the fiscal 2020 Market Unit grants, the performance during the actual performance period resulted in a Company rTSR in the 44.4% percentile, resulting in an achievement of 88.9%.

TIME-BASED RESTRICTED STOCK UNITS

For fiscal 2022, 25% of each NEO’s target long-term incentive compensation value was awarded in RSUs. The number of RSUs awarded was equal to the compensation value divided by the price of our Common Stock on the date of award. Typically, one-third of the RSUs awarded vest on each anniversary of the award date. See “Executive Compensation — Grants of Plan-Based Awards Table.”

TIME-BASED STOCK OPTIONS

For fiscal 2022, 25% of each NEO’s target long-term incentive compensation value was awarded in stock options. The number of stock options awarded was equal to the compensation value divided by the grant date fair value of our Common Stock on the date of award. Typically, one-third of the stock options awarded vest on each anniversary of the award date. Due to the rules for how the grant date fair value of long-term incentive awards must be calculated for accounting purposes, the 2022 Summary Compensation Table may not reflect the same stock option values described above. In addition, accounting values can increase or decrease each year, causing volatility in the long-term incentive awards reported. The amounts reported in the Option Awards column in the 2022 Summary Compensation Table represent the grant date fair value of stock option awards granted under the Stock Plan to each of the NEOs, calculated in accordance with ASC Topic 718. We use a Black-Scholes model when determining the grant date fair value of stock options. For information on the assumptions used by us in calculating these values, see Note 12 to our consolidated financial statements in the Form 10-K. To see the value actually received upon exercise of options by the NEOs in fiscal 2022, refer to the 2022 Option Exercises and Stock Vested table in this Proxy Statement. Outstanding option awards are reflected in the 2022 Outstanding Equity Awards table in this Proxy Statement. Also see the “Executive Compensation — Grants of Plan-Based Awards Table” for additional information.

TIMING OF EQUITY AWARDS

While the Compensation Committee may grant equity-based awards at any of its scheduled meetings or by unanimous written consent, it generally establishes awards for executives at its November or December meeting each year, except for awards related to promotions or new hires. Awards approved during scheduled meetings become effective and are priced as of the date of approval or as of a predetermined future date based on a date of hire. Awards approved by unanimous written consent become effective and are priced as of a predetermined future date. All stock options have a per-share exercise price equal to the closing stock price on the NYSE on the date of the award.

Other Cash and Equity Awards

None.

Retirement Benefits

We offer retirement benefits to our NEOs and other employees intended to provide a competitive source of retirement income. These retirement benefits are provided through the vehicles described below.

50 MUELLER WATER PRODUCTS, INC.

EXECUTIVE COMPENSATION

RETIREMENT SAVINGS PLAN APPLICABLE TO EMPLOYEES GENERALLY

The Mueller Group LLC Retirement Savings Plan is a 401(k) plan that provides retirement benefits for our non-union employees and those of our participating subsidiaries. Each of our NEOs participated in the plan in fiscal 2022 on the same basis as our other eligible employees, under which we make matching contributions in accordance with the terms of that plan.

Other Benefits

PERQUISITES

We provide certain perquisites to our NEOs that the Compensation Committee believes are reasonable and consistent with our overall compensation program. In fiscal 2022, the Compensation Committee offered the NEOs limited perquisites, including a car allowance (excluding Messrs. Helms and Takeuchi), life insurance, supplemental long-term disability insurance and reimbursement for certain financial planning and annual physical examination expenses. See “Executive Compensation — Summary Compensation Table — All Other Compensation.”

SEVERANCE BENEFITS

Each NEO is entitled to severance benefits. See “Executive Compensation — Potential Payments Upon Termination or Change-in-Control.”

CHANGE-IN-CONTROL BENEFITS

Change-in-control agreements are used to create incentives for executives to build stockholder value and to seek the highest value possible for stockholders should we be acquired, despite the risk of losing employment. Our change-in-control agreements for executives provide for vesting of outstanding equity-based awards and payment of severance amounts upon a change-in-control and operate with a “double trigger” for severance payments and equity awards, meaning severance payments and accelerated vesting of equity awards do not occur unless the executive’s employment is involuntarily terminated (other than for Cause or for termination for Good Reason as defined in the agreements) within 24 months following a change-in-control. The agreements also contain a “best-of-net” provision, so that, in the event excise taxes would be imposed on payments under the agreements, the NEO will, at his or her discretion, either (1) pay the excise tax without assistance from the Company or (2) have the payments reduced to an amount at which an excise tax would no longer be payable.

The Company provides NEOs without a change-in-control agreement with change-in-control benefits via the Company's executive severance plan approved by the Compensation Committee and instituted by the Company in January 2020. For applicable employees, the executive severance plan provides, upon a change-in-control, for vesting of outstanding equity-based awards if a replacement award (as defined in the executive severance plan) is not available and for payment of severance amounts if the executive’s employment is involuntarily terminated (other than for Cause or for termination for Good Reason as defined in the agreement) within 24 months following a change-in-control, i.e., a “double trigger.”

EMPLOYEE STOCK PURCHASE PLAN

Our Employee Stock Purchase Plan (“ESPP”) provides all of our employees an opportunity to purchase Common Stock, subject to certain restrictions, through regular payroll deductions.

HEALTH AND WELFARE BENEFITS

EXECUTIVE COMPENSATION

Other Factors Considered by the Compensation Committee

Risk and Incentive Compensation

The Compensation Committee has conducted an assessment of our compensation policies and practices and does not believe these policies and practices are reasonably likely to have a material adverse effect on us. This assessment included a review of the risk profile of our compensation policies and practices for all employees. To facilitate its review, the Compensation Committee engaged its compensation consultant to review our compensation structure to identify design elements that might encourage excessive risk taking. The compensation consultant discussed its review and conclusions with the Compensation Committee. In conducting its review, the Compensation Committee noted several policies and practices that mitigate risk, including:

•Using multiple performance measures in annual incentive awards and capping payout levels;

•Maintaining the ability to reduce annual incentive awards, based on its independent judgment;

•Using multiple long-term incentive vehicles;

•Using overlapping multi-year award cycles in connection with performance shares and capping payout levels; and

•Maintaining stock ownership guidelines, an anti-hedging policy, an anti-pledging policy and a clawback policy.

Tally Sheets

The Compensation Committee regularly reviews “tally sheets” for each executive. The tally sheets contain information concerning prior years’ compensation, proposed compensation for the current year, outstanding equity-based awards (both vested and unvested) and various termination-of-employment scenarios. The tally sheets assist the Compensation Committee in evaluating the many facets of executive compensation, understanding the magnitude of potential payouts as a result of termination-of-employment scenarios and considering changes to our compensation programs, arrangements and plans in light of emerging trends.

Other Compensation Practices and Policies

Role of Compensation Consultant in Compensation Decisions

The Compensation Committee has sole authority to select and retain a compensation consultant, including authority to approve fees and retention terms. For fiscal 2022, the Compensation Committee retained Farient Advisors, LLC as its compensation consultant. The Compensation Committee reviews the performance of its compensation consultant annually.

In fiscal 2022, the compensation consultant’s responsibilities included, but were not limited to:

•Providing recommendations regarding the composition of our Peer Group;

•Preparing and analyzing Peer Group compensation and plan design data;

•Reviewing and advising on the performance measures to be used in incentive awards;

•Valuing equity-based awards; and

•Reviewing and advising on principal aspects of executive and non-employee director compensation, including base salaries, bonuses, perquisites and equity-based awards for executives, and cash compensation and equity-based awards for non-employee directors.

The Compensation Committee considered the independence of its compensation consultant in light of standards under NYSE listing standards. The Compensation Committee requested and received a letter from the compensation consultant addressing its independence, including the factors described below:

•Other services provided to us by the consultant;

•Fees paid by us as a percentage of the consultant’s total revenue;

•Policies or procedures maintained by the consultant that are designed to prevent a conflict of interest;

•Any business or personal relationships between the individual consultants involved in the engagement and a member of the Compensation Committee;

•Any Common Stock owned by the individual consultants involved in the engagement; and

52 MUELLER WATER PRODUCTS, INC.

EXECUTIVE COMPENSATION

•Any business or personal relationships between our executives and the consultant or the individual consultants involved in the engagement.

The Compensation Committee took into account these considerations, along with other factors relevant to the compensation consultant’s independence from management, and concluded the compensation consultant is independent and the engagement of the compensation consultant and the services rendered by the compensation consultant did not raise any conflict of interest.

Role of Management in Compensation Decisions

The Compensation Committee reviews information provided by its compensation consultant and uses that information as a reference point for the components of compensation. The Compensation Committee and the Chief Executive Officer discuss the financial metrics and operational goals intended to closely align performance targets of the business units and the Company as a whole with our strategic goals. The Chief Executive Officer makes recommendations to the Compensation Committee for executives other than himself with respect to annual salary adjustments, annual incentive adjustments and grants of equity-based awards under our incentive plans. The Compensation Committee makes the final decision with respect to the compensation of these executives, taking into consideration the Chief Executive Officer’s recommendations.

The Compensation Committee annually receives input from the entire Board with respect to the Chief Executive Officer’s performance and recommends his compensation level to the Board. The Board discusses and approves the annual salary of the Chief Executive Officer. The Chair of the Compensation Committee and Non-Executive Chair of the Board meet with the Chief Executive Officer to discuss the Chief Executive Officer’s performance and compensation based on evaluations received from the Board.

In fiscal 2022, the Chief Executive Officer was present at all of the Compensation Committee meetings but was excused from the executive sessions of the Compensation Committee and did not participate in deliberations during which his compensation was discussed.

Income Tax Consequences of Executive Compensation

Our compensation programs were designed to permit us to deduct compensation expense under Section 162(m) of the Internal Revenue Code, which historically limited the tax deductibility of annual compensation paid to executives to $1 million, unless the compensation qualified as “performance-based.” The exemption from Section 162(m)’s deduction limit for performance-based compensation has been repealed (subject to certain transition rules), effective for taxable years beginning after December 31, 2017, such that compensation paid to our NEOs in excess of $1 million is generally not deductible. As a result, we may no longer take a deduction for any compensation paid to our NEOs in excess of $1 million. In fiscal 2022 and in plans for fiscal 2023, the Compensation Committee continued to design compensation programs and make grants that it believes are performance-based and well aligned with the interests of our stockholders.

Previous grants made under the Stock Plan, and the PRSUs granted thereunder, as well as the annual cash incentive award, were structured and were intended to permit such awards to qualify as “performance-based” compensation to maximize the tax deductibility of these awards under Section 162(m). Those awards may not be fully deductible under all circumstances, as a number of additional requirements must be met for the awards to qualify as “performance-based” compensation.

Compensation Recovery (Clawback) Policy

NEOs are required, to the extent required by law, to reimburse us following the publication of a restatement of our financial statements due to material noncompliance with any financial reporting requirement under the securities laws as a result of misconduct for (a) incentive-based or equity-based compensation received and (b) any profits realized from the sale of our securities during the 12 months prior to discovery of the noncompliance. The Compensation Committee has exclusive authority to interpret and enforce this provision.

The Compensation Committee has adopted a “Clawback Policy” to recover pay that is determined to have been wrongfully earned by managerial or executive employees, including our NEOs. As a result, all equity awards granted after November 30, 2009 include a clause that reduces the number of equity-based awards upon the occurrence of certain events. The Compensation Committee has the exclusive authority to interpret the Clawback Policy and may offset compensation as necessary to recover amounts due under the Clawback Policy.

PROXY STATEMENT FOR 2023 ANNUAL MEETING 53

EXECUTIVE COMPENSATION

Prohibition on Hedging and Pledging

We do not allow directors or employees to hedge the value of our equity securities held directly or indirectly by them. Our policy prohibits the purchase or sale of puts, calls, options or other derivative securities based on our securities, as well as hedging or monetization transactions, purchases of our equity securities on margin and borrowing against any account in which our securities are held. We prohibit pledging of Common Stock by executives or directors.

Stock Ownership Guidelines

The Compensation Committee has adopted stock ownership guidelines to promote a high level of stock retention among executives and non-employee directors. The guidelines require that the total value of the executive’s or non-employee director’s holdings of Common Stock must equal or exceed the specified target value shown below.

Position/Title	Target Ownership
Chief Executive Officer and President		6x base salary
Executive Vice Presidents		3xbase salary
Senior Vice Presidents		2x base salary
Vice Presidents		1x base salary
Non-Employee Directors		5x annual retainer

Participants have five (5) years from the date a participant becomes subject to the program to achieve the applicable stock ownership target. If a participating individual is promoted, the promoted participant has three (3) years from the date of promotion to increase his or her holdings to meet the applicable stock ownership requirements. All NEOs and directors are in compliance with our stock ownership guidelines. Our stock ownership guidelines are available on our website at www.muellerwaterproducts.com.

Report of the Compensation and Human Resources Committee

The Compensation Committee participated in the preparation of the Compensation Discussion and Analysis. Based on its review and discussions with management, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

(1)Salaries for the NEOs are adjusted, as appropriate, annually and are effective on February 1.

(2)“Stock Awards” comprise RSUs, Market Units and RONA Units. All RSUs and Market Units are granted on the date of award. RONA Units are granted annually in three equal tranches, beginning on the date of award. For fiscal 2022, the Stock Awards amounts include the aggregate grant date fair values of RSUs and Market Units granted in fiscal 2022 and the third tranche of RONA Units awarded in fiscal 2020 for the fiscal 2022 performance period. The dollar amounts shown for Stock Awards represent the aggregate grant date fair values calculated in accordance with ASC 718, Stock Compensation. See “Compensation Discussion and Analysis — Compensation Elements — Long-Term Equity-Based Compensation” for more information. The grant date fair value of the fiscal 2020, fiscal 2021 and fiscal 2022 Market Units was $14.94, $15.39 and $15.76, respectively.

For more information regarding how the Company calculated these amounts, see the audited financial statements contained in our fiscal 2022 Form 10-K. The calculated compensation expense of the option awards recognized for financial reporting purposes will vary from the actual amount ultimately realized by the NEOs due to stock price fluctuations and timing factors related to the NEO’s realization of value from the option. To see the value actually received upon exercise of options by the NEOs in 2022, refer to the 2022 Option Exercises and Stock Vested table. Additional information on all outstanding option awards is reflected in the 2022 Outstanding Equity Awards table and the Grant of Plan-Based Awards Table of this Proxy Statement.

(1)Amounts represent the range of possible cash payouts for fiscal 2022 awards under the annual cash incentive plan as described in “Compensation Discussion and Analysis — Compensation Elements — Annual Cash Incentive Awards.” The amounts that were earned based on actual performance for fiscal 2022 were paid in December 2022 and are shown in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table.

(2)Represents time-based RSUs. Each RSU entitles the grantee to receive one share of Common Stock upon vesting. The RSUs generally vest in equal installments on the first, second and third anniversaries of the award date. See “Compensation Discussion and Analysis — Compensation Elements — Long-Term Equity-Based Compensation — Time-Based Restricted Stock Units” for more information.

(3)Represents the range of shares of Common Stock that may vest after the end of the three-year cumulative award period applicable to a PRSU award based solely on rTSR performance goals established in fiscal 2022, i.e., Market Units, assuming achievement of threshold, target and maximum performance. The grant date fair value of the fiscal 2022 Market Units was $15.76. See “Compensation Discussion and Analysis — Compensation Elements — Long-Term Equity-Based Compensation — Performance-Based Restricted Stock Units” for more information.

(4)Represents stock options. Upon vesting, each stock option entitles the NEO to purchase one share of our common stock at a specified exercise price. These stock options vest in equal installments on the first, second and third anniversary of the date of award. Once vested, options will generally remain exercisable until their normal expiration dates, which are ten years from the grant date. Grantees generally have ninety days to exercise any vested options upon termination of employment. This period is extended to one year in the event termination results from death and disability and two years in the case of retirement. All outstanding options will immediately terminate if the grantee is terminated for cause. The grant date fair value of the fiscal 2022 stock options was $3.43.

(5)Represents the range of shares of Common Stock that may vest after the end of the three-year award cycle applicable to a PRSU award solely with respect to the fiscal 2022 RONA performance period goals established in fiscal 2022, i.e., RONA Units, assuming achievement of threshold, target and maximum performance.

(6)Each stock option granted during fiscal 2022 was granted with a per-share exercise price equal to the closing price of the underlying common stock on the New York Stock Exchange on the award date.

(7)See footnote 2 and footnote 3 to the “Summary Compensation Table” for a description of the methods used to determine grant date fair value of equity-based awards.

(8)Mr. Helms received an award commensurate with his position and in line with awards granted to the then-current senior officers of the Company at the time of his hiring. This row represents the range of shares of Common Stock that may vest after the end of the three-year award cycle applicable to a PRSU award solely with respect to the fiscal 2022 RONA performance period goals established in fiscal 2022, i.e., RONA Units, assuming achievement of threshold, target and maximum performance.

PROXY STATEMENT FOR 2023 ANNUAL MEETING 59

EXECUTIVE COMPENSATION

Employment, Severance and Change-in-Control Arrangements

At September 30, 2022, we maintained employment agreements with each NEO except as noted. Each agreement provides for an annual equity opportunity, which is subject to the discretion of the Compensation Committee, and commensurate with their executive-level position. Each agreement also entitles the employee to receive reimbursement for financial planning services and the cost of an annual physical exam. The following table sets forth certain information with respect to these agreements.

Name	Base Salary Rate(1) ($)	Annual Target Bonus as Percent of Base Salary(2) (%)	Monthly Car Allowance ($)	Annual Vacation	Severance Benefits as Percent of Salary(3) (%)
J. Scott Hall	854,000	105	2,000	4 weeks	300.0
Marietta Edmunds Zakas	454,564	70	1,500	4 weeks	262.5
Steven S. Heinrichs	459,426	60	1,500	4 weeks	262.5
Todd P. Helms(4)	372,203	60	N/A	4 weeks	100.0
Kenji Takeuchi(4)	374,920	50	N/A	4 weeks	100.0

(1)Salaries are reviewed annually. Amounts shown represent annual salary rates as of September 30, 2022.

(2)Payout can range from zero to up to twice the amount of the target based on the satisfaction of predetermined financial, market and operational performance objectives.

(3)Other severance benefits are paid in monthly installments over 24 months, in the case of Mr. Hall, and over 18 months in the case of each other NEO, together with a lump sum payment of unpaid salary and other benefits.

(4)Messrs. Helms and Takeuchi are subject to the Company's executive severance plan and do not maintain separate employment agreements.

At September 30, 2022, we also maintained change-in-control arrangements with each NEO. Under the existing change-in-control agreements with Messrs. Hall and Heinrichs and Ms. Zakas, upon a change-in-control (as defined in the agreement) of the Company and (i) the executive’s employment is terminated other than for Cause or for Good Reason (each as defined in the agreement) within 24 months following a change-in-control or (ii) a replacement award (as defined in the agreement) was not available (i.e., a double trigger), all outstanding options and RSUs would immediately vest. The value of PRSUs reflects the pro rata portion of shares earned during the performance period and payout at target for future performance periods within the award cycle. In addition, if the executive’s employment is terminated other than for Cause or for Good Reason within 24 months following a change-in-control, the executive would be entitled to a lump-sum severance payment equivalent to 2.0x base salary and annual incentive bonus (generally calculated as the greater of (i) the Executive’s annual target bonus and (ii) the average of actual annual incentive bonuses over the preceding three years) and continuation of certain benefits, such as group life and medical insurance coverage for a period of 24 months. The agreements also contain a “best-of-net” provision, so that, in the event excise taxes would be imposed on payments under the agreements, the NEO will either (1) pay the excise tax without assistance from the Company or (2) have the payments reduced to an amount at which an excise tax would no longer be payable, based on which result is more favorable to him or her on an after-tax basis.

Messrs. Helms and Takeuchi receive change-in-control benefits under the executive severance plan. The executive severance plan provides, upon a change-in-control, for vesting of outstanding equity-based awards if a replacement award (as defined in the Executive Severance Plan) is not available and for payment of cash severance amounts if the NEO’s employment is involuntarily terminated (other than for Cause or for termination for Good Reason as defined in the executive severance plan) within 24 months following a change-in-control (i.e., a double trigger). Such cash severance payments would include a lump-sum payment equivalent to the sum of 1.0x base salary and annual target incentive bonus, a pro rata amount of his annual target incentive bonus (prorated based upon the time of service during the applicable fiscal year) and cash equivalent amounts related to other benefits.

Potential Payments Upon Termination or Change-in-Control

The following table sets forth the potential benefits each NEO would be entitled to receive upon termination of employment in the situations outlined below. The NEO would not be entitled to the severance benefits described below if he or she terminates employment without Good Reason or is terminated for Cause. The amounts shown are estimates and do not necessarily reflect the actual amounts that would be paid to the NEOs, which would only be known at the time they become eligible for payment. The amounts shown are the amounts that could be payable under existing plans and arrangements if the NEO’s employment had terminated on September 30, 2022.

The termination events pursuant to which the NEOs are entitled to potential payments are as follows:

A - Severance arrangement for termination without Cause or for Good Reason

B - Termination without Cause after a change-in-control

C - Death, disability or retirement

(1)Each is entitled to a pro rata share of the current fiscal year bonus in the event of termination without Cause or after a change-in-control. Amounts in this table assume a termination date of September 30, 2022 and represent the actual bonus paid for fiscal 2022 since this amount would not have otherwise been paid at that date.

(2)The value of stock options is the difference between the closing price of Common Stock on September 30, 2022 and the option exercise prices per share multiplied by the number of options. The value of RSUs is the closing price of Common Stock on September 30, 2022 multiplied by the number of RSUs. The value of PRSUs reflects the pro rata portion of shares earned during the performance period and payout at target for future performance periods within the award cycle. The closing price of our Common Stock on September 30, 2022 on the NYSE was $10.27.

(3)For all NEOs, excluding Messrs. Helms and Takeuchi, health and welfare benefits are continued for up to 42 months from the separation date based on the current elections and plan premiums.

(4)Services in Case A (without Cause termination) will be reasonable in our sole discretion. Services in Case B (change-in-control termination) will be provided for up to two years but will not exceed 35% of the base salary at the time of termination for Messrs. Hall and Heinrichs and Ms. Zakas or $25,000 for Messrs. Helms and Takeuchi.

(5)Cash severance in Case A (without Cause termination) is equal to a percentage of current annual base salary plus accrued vacation. The percentage applicable to Mr. Hall is 300%. The percentage applicable to Mr. Heinrichs and Ms. Zakas is 262.5%. The percentage applicable to Messrs. Helms and Takeuchi is 100% plus an amount equal to a pro rata annual incentive bonus calculated at target goals. Other severance benefits, if applicable, are paid in monthly installments over 24 months in the case of Mr. Hall and over 18 months in the case of each other NEO, together with a lump sum payment of unpaid salary and other benefits.

PROXY STATEMENT FOR 2023 ANNUAL MEETING 61

EXECUTIVE COMPENSATION

(6)Cash severance in Case B (change-in-control termination) for Messrs. Hall and Heinrichs and Ms. Zakas is equal to two times annual base salary plus two times the greater of (i) the annual target bonus and (ii) the average bonus over the last three years, plus accrued vacation. Cash severance in Case B (change-in-control termination) for Messrs. Helms and Takeuchi is equal to one times annual base salary and target annual incentive bonus plus pro rata target annual incentive bonus, accrued vacation and ancillary medical benefits. Accrued vacation assumes no vacation has been taken.

CEO Pay Ratio Disclosure

For fiscal 2022, (i) the annual total compensation of our median employee (excluding our CEO) was $60,507 and (ii) the annual total compensation of our CEO was $4,807,096. Based on this information, the ratio of the annual total compensation of our CEO to that of the median employee is approximately 79 to 1. Our employee population consists of approximately 3,545 employees located throughout the world, with approximately 81% in the United States.

To identify the median employee for fiscal 2022, we included all part-time and full-time employees that were employed for any portion of fiscal 2022 so long as they were still actively employed on September 30, 2022. Compensation elements used included regular pay (base salary for exempt population and hourly wages for non-exempt population), bonuses, overtime, shift pay and paid time off. Commissions and executive perquisites were omitted from the median employee selection calculation. Using this methodology, we determined the “median employee” was a full-time, hourly employee located in the United States.

ADVISORY VOTE ON FREQUENCY OF ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION

Proposal Three
Advisory Vote on the Frequency of the Advisory Vote to Approve Executive Compensation
	The Board recommends voting on executive compensation ANNUALLY.

At our 2011 Annual Meeting, we first provided our stockholders with the opportunity to cast an advisory vote on how frequently they would like to vote on our executive compensation, which, as described in Proposal Two, is commonly referred to as “Say-on-Pay.” Based on the previous voting results, our Board determined to hold Say-on-Pay votes annually. SEC rules require us to ask our stockholders, at least every six years, how often they would like for us to hold Say-on-Pay votes. Accordingly, we are requesting your advisory vote this year to determine the frequency of future Say-on-Pay votes.

By voting on this Proposal Three, stockholders may indicate whether they would prefer that we continue to hold an advisory vote on our executive compensation annually, or whether they prefer such vote to be held every two or three years.

The Board believes that an annual vote is the most effective means for ensuring that our executive compensation policies and procedures are strongly aligned with the interests of our stockholders and are effective in implementing our compensation philosophy and in achieving our strategic goals. The Board’s belief is further based on the premise that this recommendation can be modified in future years if it becomes apparent that a vote once every year is not meaningful or a different voting frequency is recommended by best corporate governance practices.

Accordingly, we ask for stockholder approval of the following resolution:

RESOLVED, that the stockholders approve, on an advisory basis, an annual advisory vote on executive compensation.

This vote is advisory and therefore not binding on us, the Board or the Compensation Committee. The Compensation Committee will consider the result of this year’s vote, as well as other communications from stockholders relating to our compensation practices, and take them into account in future determinations concerning our executive compensation programs.

RATIFICATION OF APPOINTMENT OF REGISTERED PUBLIC ACCOUNTING FIRM

Proposal Four
Ratification of the Appointment of Our Independent Registered Public Accounting Firm for Fiscal 2023
	The Board recommends a vote FOR this proposal.

The Audit Committee has authority to retain and terminate the services of our independent registered public accounting firm. The Audit Committee has appointed Ernst & Young LLP (“EY”) as the independent registered public accounting firm to audit our consolidated financial statements and internal control over financial reporting for the fiscal year ending September 30, 2023, subject to negotiation of definitive fee arrangements. Although stockholder ratification of EY’s appointment is not required, the Board believes submitting the appointment to our stockholders for ratification is a matter of good corporate governance. Even if stockholders ratify the appointment of EY, the Audit Committee, in its discretion, may change the appointment at any time during the fiscal year if it determines that a change would be in the best interest of the Company and its stockholders.

See below for a description of the fees EY billed us for fiscal 2022 and fiscal 2021.

A representative of EY is expected to be present at the Annual Meeting. The representative will have an opportunity to make a statement and will be available to respond to stockholder questions.

Pre-Approval of Services Performed by the Independent Registered Public Accounting Firm

The Audit Committee has adopted procedures for pre-approving all audit and non-audit services provided by the independent registered public accounting firm. For both types of pre-approval, the Audit Committee considers whether the services are consistent with the Securities and Exchange Commission (“SEC”) rules on auditor independence and whether the independent registered public accounting firm is able to provide the most effective service. Audit and non-

(1)The address of each of our directors and executive officers is c/o Mueller Water Products, Inc., 1200 Abernathy Road, N.E., Suite 1200, Atlanta, Georgia 30328.

(2)Beneficial ownership as reported in the table has been determined in accordance with the rules of the SEC. Under those rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment power,” which includes the power to dispose of, or to direct the disposition of, such security. The person is also deemed to be a beneficial owner of any security of which that person has a right to acquire beneficial ownership within 60 days. Under such rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which he or she may disclaim any beneficial interest. Except as indicated in other notes to this table, directors and executive officers possessed sole voting and investment power with respect to all shares of Common Stock referred to in the table. See “Executive Compensation — Outstanding Equity Awards at Fiscal Year-End Table” for more information concerning outstanding equity awards to our NEOs and “Director Compensation — Director Compensation Summary” for more information concerning outstanding equity awards to our directors.

(3)Each non-employee director, with the exception of Dr. Ortiz and Messrs. Sharritts and Slobodow, is “retirement-eligible” under and for purposes of the Stock Plan. Accordingly, for purposes of this table, all outstanding equity-based awards for the retirement eligible non-employee directors are deemed vested. Beginning with the equity-based awards granted to directors in January 2014, all such awards to directors require a grantee who is or becomes retirement-eligible prior to an initial vesting date to remain in continuous service from the grant date through at least the first anniversary thereof to receive accelerated vesting upon retirement. The beneficial ownership reported in the table assumes each grantee of an award on February 7, 2022 will remain in continuous service through February 7, 2023 and/or all awards granted on February 7, 2022 will vest on or before February 7, 2023. Excludes Mr. Tokarz's 208,107 stock equivalent shares of Common Stock, which settle in cash in accordance with the Directors' Deferred Fee Plan.

(4)As reported on Schedule 13G/A filed with the SEC on February 10, 2022, The Vanguard Group, Inc. has sole investment discretion with respect to 14,103,557 shares, shared voting power with respect to 142,134 shares and shared investment discretion with respect to 275,193 shares.

(5)As reported on Schedule 13G filed with the SEC on February 14, 2022, Impax Asset Management Group plc and Impax Asset Management Limited each have sole investment discretion and sole voting power with respect to 12,768,256 shares.

(6)As reported on Schedule 13G/A filed with the SEC on February 3, 2022, BlackRock, Inc. has sole investment discretion with respect to 12,706,693 shares and sole voting power with respect to 12,410,514 shares.

(7)As reported on Schedule 13F-HR filed with the SEC on November 10, 2022 to report beneficial ownership of shares of the Company’s common stock as of September 30, 2022, and as confirmed by Nuance Investments, LLC, Nuance Investments, LLC has sole investment discretion and sole voting power with respect to 11,428,817 shares.

(8)As reported on Schedule 13G filed with the SEC on February 14, 2022, T. Rowe Price Associates, Inc. has sole investment discretion with respect to 8,369,160 shares and sole voting power with respect to 2,278,347 shares.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires executive officers and directors and persons who beneficially own more than 10% of a company’s common stock (together, “Reporting Persons”) to file initial reports of ownership and reports of changes in ownership with the SEC. Reporting Persons are required by SEC rules to furnish companies with copies of all Section 16(a) forms they file. Based solely on a review of copies of such forms furnished to us and written representations from the executive officers and directors, we believe our Reporting Persons complied with all Section 16 filing requirements during fiscal 2022, with the exception of (i) one amended Form 3 filing for Mr. Floyd in connection with previously unreported de minimis dividend reinvestments; (ii) one Form 5 filing for Mr. Floyd for fiscal 2020 and 2021 in connection with previously unreported de minimis dividend reinvestments; and (iii) one Form 4 filing for Todd Helms in connection with previously unreported de minimis dividend reinvestments as well as shares withheld to cover the tax liability on the lapse of restrictions on vested awards, which filing was made one business day late due to administrative error.

Will any other business be conducted at the Annual Meeting?

Management is not aware of any items, other than those referred to in this Proxy Statement, that may properly come before the Annual Meeting.

How are proxies voted?

Shares represented by all valid proxies received on time will be voted as specified. If a valid proxy form is received and does not indicate specific choices, the shares will be voted in accordance with the Board’s recommendations. The Board has designated each of Scott Hall, Steven S. Heinrichs and Chason Carroll as proxies for the Annual Meeting.

How may I vote?

If your shares are registered directly in your name with our transfer agent, you are a “registered stockholder.” Registered stockholders may vote by:

•Internet at the web address noted in the Notice of Internet Availability of Proxy Materials, proxy materials email or proxy card that you received (we encourage you to vote in this manner);

•Telephone through the number noted in the proxy card that you received (if you received a proxy card);

•Signing and dating your proxy card (if you received a proxy card) and mailing it to the indicated address; or

•Virtually attending the Annual Meeting and voting your shares.

If your shares are registered in the name of your broker, bank or other agent, you are the “beneficial owner” of those shares and those shares are considered as held in “street name.” If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should have received a proxy card and voting instructions with these proxy materials from that organization rather than directly from us. Simply complete and mail the proxy card to ensure that your vote is counted. You may be eligible to vote your shares electronically over the Internet or by telephone. A large number of banks and brokerage firms offer Internet and telephone voting. If your bank or brokerage firm does not offer Internet or telephone voting information, please complete and return your proxy card in the self-addressed, postage-paid envelope provided. To virtually vote at the Annual Meeting, you must first obtain a valid legal proxy from your broker, bank or other agent and then register in advance to virtually attend the Annual Meeting. Follow the instructions from your broker or bank included with these proxy materials or contact your broker or bank to request a legal proxy form.

After obtaining a valid legal proxy from your broker, bank or other agent, to then register to virtually attend the Annual Meeting, you must e-mail to Computershare at legalproxy@computershare.com your name and e-mail address and either (a) the forwarded e-mail from your bank, broker or nominee containing your legal proxy or (b) an attached image of your legal proxy. Upon successful preregistration, a beneficial owner will receive a confirmation e-mail from Computershare confirming registration and providing a control number to enter the virtual meeting as a stockholder. See “How can I register for the Annual Meeting?” below for additional details.

If you plan to vote other than by virtually attending the Annual Meeting and voting your shares, your vote must be received by 10:00 a.m., Eastern Time, on February 7, 2023.

How can I ask questions pertinent to meeting matters?

Stockholders may submit questions either before the annual meeting (beginning January 31, 2023) or during the Annual Meeting. If you wish to submit a question either before or during the meeting, please log into www.meetnow.global/MLMGXU5 and enter your 15-digit voter control number, then follow the instructions to submit a question. Questions pertinent to meeting matters will be answered during the meeting, subject to time limitations.

PROXY STATEMENT FOR 2023 ANNUAL MEETING 69

QUESTIONS ABOUT VOTING AND THE ANNUAL MEETING

How can I change my vote?

You can revoke a proxy prior to the completion of voting at the Annual Meeting by:

•Voting again using the Internet or by telephone prior to the Annual Meeting;

•Delivering a later-dated proxy card; or

•Voting your shares virtually at the meeting (if you are a beneficial stockholder).

What constitutes a quorum for the Annual Meeting?

The holders of a majority of the voting power of the outstanding shares of Common Stock at the close of business on the record date must be present, either personally or represented by proxy, to constitute a quorum necessary to conduct the Annual Meeting. Shares represented by proxies received but marked as abstentions or as withholding voting authority for any or all director nominees, and shares represented by proxies received but reflecting broker non-votes, will be counted as present at the Annual Meeting for purposes of establishing a quorum.

Why did I receive a Notice of Internet Availability of Proxy Materials in the mail instead of a printed set of proxy materials?

We are permitted by SEC rules to furnish proxy materials to stockholders by providing access to those documents on the Internet. Stockholders will not receive printed copies of the proxy materials unless they request them. The Notice provides instructions on how to access and review the Proxy Statement and the Annual Report over the Internet at www.proxyvote.com (for beneficial stockholders) and www.envisionreports.com/MWA (for registered stockholders), and how to submit a proxy over the Internet. If you would like to receive a paper or email copy of the proxy materials, please follow the instructions in the Notice.

What does it mean if I receive more than one Notice, proxy materials email or proxy card?

It means you have multiple accounts holding Common Stock with brokers and/or our transfer agent. You will need to vote separately with respect to each Notice, proxy materials email or proxy card you receive.

What do I need to do if I want to attend the Annual Meeting?

The Annual Meeting will be a completely virtual meeting of stockholders, which will be conducted exclusively by webcast. You are entitled to participate in the Annual Meeting only if you were a stockholder of the Company as of the close of business on the Record Date or if you hold a valid proxy for the Annual Meeting. There is no physical location for this meeting.

You can attend the Annual Meeting online, vote and submit questions pertinent to meeting matters during the meeting by visiting www.meetnow.global/MLMGXU5. Please follow the registration instructions below.

The Annual Meeting will begin promptly at 10:00 a.m., Eastern Time, on February 7, 2023. We encourage you to access the meeting prior to the start time in order to log in to the live webcast and test your computer audio system.

How can I register for the Annual Meeting?

If you are a registered stockholder (i.e., you hold your shares through our transfer agent, Computershare), you do not need to register to attend the Annual Meeting virtually on the Internet. Please follow the instructions on the Proxy Card or Notice that you received with this Proxy Statement. To access the meeting, you will need the 15-digit control number printed on your card or notice.

If you are a beneficial owner (i.e., you hold your shares through an intermediary, such as a bank or broker), you must register in advance to attend the Annual Meeting virtually on the Internet. To register, you must submit a legal proxy that reflects your proof of proxy power. The legal proxy must reflect your Mueller Water Products, Inc. holdings along with your name. Please forward a copy of the legal proxy and your email address to Computershare either by email to legalproxy@computershare.com (forward the email from your broker or attach an image of your legal proxy) or by mail to Computershare, Mueller Water Products, Inc. Legal Proxy, P.O. Box 43001, Providence, RI 02940-3001.

You will receive a confirmation of your registration by email (or by mail if no email address is provided) after Computershare receives your registration materials.

How are proxies solicited and what is the cost?

We bear all expenses incurred in connection with the solicitation of proxies. We have engaged Innisfree M&A Incorporated to assist with the solicitation of proxies for an estimated fee of $150,000, plus expenses. We will reimburse brokers, fiduciaries and custodians for their costs in forwarding proxy materials to beneficial holders of Common Stock. Our directors, officers and employees also may solicit proxies in return for no additional compensation.

How can I submit my proposal for inclusion in next year’s proxy?

•When to submit? Any stockholder proposals submitted in accordance with Rule 14a-8 must be received at our principal executive offices no later than August 21, 2023.

We encourage stockholders to contact our Corporate Secretary prior to submitting a stockholder proposal or any time they have concerns about us.

EXHIBIT A - RECONCILIATION OF NON-GAAP PERFORMANCE MEASURES TO GAAP PERFORMANCE MEASURES

The Company presents adjusted net income, adjusted net income per diluted share, adjusted operating income, and adjusted EBITDA as performance measures because management uses these measures in evaluating the Company’s underlying performance on a consistent basis across periods and in making decisions about operational strategies. Management also believes these measures are frequently used by securities analysts, investors and other interested parties in the evaluation of the Company’s recurring performance. These are considered measures not calculated in accordance with GAAP and are therefore considered non-GAAP measures. The Company provides the following reconciliations of these non-GAAP measures to their most comparable GAAP measures.
