PROXY STATEMENT FOR 2026 ANNUAL MEETING 1

LETTER TO STOCKHOLDERS

DEAR FELLOW STOCKHOLDERS,

As we look ahead to our 2026 Annual Meeting of Stockholders (“Annual Meeting”) of Mueller Water Products (“Mueller”), we can each take pride in our fiscal 2025 – keynoted by record setting financial results and an outstanding management team leading an entire organization committed to delivering long-term value to all of our stakeholders.

Fiscal 2025 marked another year of exceptional performance for Mueller, including strong net sales growth and more than a 100 basis points increase in our adjusted EBITDA margin. Our achievements in transforming our business over the past two years have expanded our gross margin by more than 600 basis points. Our team’s unwavering commitment and relentless focus on operational excellence and customer service enabled us to grow volumes and drive meaningful margin expansion, even as they navigated a complex external operating environment. These accomplishments demonstrate the soundness of our strategies – both long and near term, the strength and depth of our leadership team, and the dedication of our talented employees who drive our success every day – building on yesterday and looking forward to tomorrow.

In keeping with the Board’s thoughtful succession planning process, Mr. Thomas Hansen will retire from the Board at the conclusion of our Annual Meeting on February 9, 2026. Tom has been a Board member for almost 15 years, and, throughout his tenure, his valued insights, strategic guidance, and deep experience have been instrumental to Mueller’s success. On behalf of the entire Board, I thank Tom for his dedicated service and his many contributions to Mueller and its stockholders.

We are pleased to announce that Mr. Gregg Sengstack has been nominated for election to the Board at the upcoming Annual Meeting. Gregg joined us as a Board Observer in September of 2025, and has already brought valuable perspectives and expertise to our discussions. We look forward to his election and to benefiting from his deep leadership experience in industrial and manufacturing sectors as Mueller continues to advance its strategic priorities.

As recently announced, Paul McAndrew, President and Chief Operating Officer, will succeed Martie Edmunds Zakas as President and Chief Executive Officer (”CEO”), effective as of the Annual Meeting on February 9, 2026. At that time, if elected, Paul will also join the Board of Directors, while Martie will retire as CEO and from the Board, continuing as a Senior Advisor through December 31, 2026, to ensure a smooth transition.

Paul has been an integral member of Mueller’s leadership team for the last three years, playing a central role in improving our organization, its operations, and financial performance. He brings deep industry expertise, strong relationships across our stakeholders, and a proven record of driving operational excellence and growth. We look forward to his leadership and to working closely with him as he guides our superb organization.

On behalf of the Board and our entire organization, I extend our sincere appreciation to Martie for her extraordinary leadership and contributions to Mueller over the past two decades. Martie has shaped the Company’s culture, driven innovation and transformation, and built significant value for all of our stakeholders. We are deeply grateful for her steadfast leadership and pleased that she will continue to support the organization during this transition period. We wish her all the best in the years ahead.

The Board, Martie, Paul, and our entire team have positioned Mueller well for continued success, driven by a clear strategy, supported by a strong financial foundation, and led by an exceptional team. As we build on our positive momentum, we remain focused on delivering sustainable growth, operational excellence, and long-term value creation for all stakeholders.

On behalf of the Board, our management, and all of our people, I thank you for being a Mueller stockholder and for your continued support of our exemplary organization.

STEPHEN C. VAN ARSDELL

Non-Executive Chair of the Board

LETTER FROM THE PRESIDENT AND CEO-DESIGNATE

DEAR FELLOW STOCKHOLDERS,

I am deeply honored that the Board has appointed me as Chief Executive Officer of Mueller Water Products, effective February 9, 2026, and nominated me for election to our Board on that date. I want to recognize the dedication and leadership of Martie Edmunds Zakas. Martie’s nearly two decades of service have helped shape Mueller into the company we are today.

Since joining Mueller three years ago, I have witnessed firsthand the passion, expertise, and commitment that our employees bring to our mission. Together, we have improved operational execution, strengthened relationships with our stakeholders and delivered outstanding results. Our achievements, including new records for net sales and adjusted EBITDA in fiscal 2025, are a testament to our employees’ hard work and dedication. The momentum that we have created over the past three years provides us with an opportunity to dream bigger, reach higher and build a company that reflects our highest aspirations.

I look forward to continuing to work closely with our entire organization and all our stakeholders to provide the highest quality products, services and solutions. Our north star will continue to be delivering products, services and solutions that make a real difference for our customers and communities.

As we look forward, my focus is clear…to build on our momentum and position Mueller for sustainable, long-term growth and value creation. To that end, we are sharpening our strategic priorities around commercial and operational excellence, accountability, disciplined capital allocation, innovation and an unwavering commitment to our customers.

I thank the Board for placing their trust in me to lead this extraordinary organization. I am equally grateful to our stockholders for your continued trust and support. We enter this next chapter with confidence, clarity and a shared purpose.

Thank you for your investment in Mueller. I look forward to updating you on our progress in the months ahead.

Sincerely,

PAUL MCANDREW

President and CEO-designate

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. Since then, 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, services, and solutions used in the transmission, distribution and measurement of water in North America. We continue to invest, invent and lead in our broad portfolio of products, service and solutions, which include engineered valves, fire hydrants, pipe connection and repair products, metering products, leak detection, pipe condition assessment, pressure management products, and software that provides critical water system data.

This breadth of portfolio 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 few 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®.

PROXY SUMMARY

Notable Achievements in Fiscal 2025



Financial Accomplishments			•Delivered second consecutive year of record net sales, gross margin, adjusted EBITDA, adjusted EBITDA margin and adjusted net income per diluted share.

Operational Improvements			•Completed the transition to our state-of-the-art brass foundry in Decatur, Illinois, and achieved our lowest total recordable incident rate in Mueller history.

Sustainability Achievements			•Achieved our initial leak detection goal of identifying 7.7 billion gallons of water loss between 2022 and 2027, three years ahead of our target date, and expanded our leak detection goal to identify 18 billion gallons of water loss by 2029.

Leadership and Culture			•Offered a variety of training programs for employees on topics ranging from leadership to skills-based training and much more.

Employee Engagement			•Conducted our annual employee experience survey with year-over-year increases in both participation and engagement.

Highlights of Fiscal 2025 Performance



	Focused on Operational Investment and Efficiencies to Increase Long-Term Stockholder Value
We generated net sales of $1,429.7 million, operating income of $260.6 million, net income of $191.7 million, adjusted earnings before interest tax depreciation and amortization (“EBITDA”) of $326.2 million, net income per diluted share of $1.22 (with adjusted net income per diluted share of $1.31) and $219.3 million net cash provided by operating activities (free cash flow of $172.0 million). Adjusted EBITDA, adjusted net income per diluted share and free cash flow 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 to GAAP measures.


	Dividend Benefits		Stockholder Value
•We paid stockholders a quarterly $0.067 per share dividend during fiscal 2025, an increase of approximately 4.7% from fiscal 2024. •We returned $41.9 million to our stockholders through dividends in fiscal 2025.		We repurchased $15 million of our outstanding Common Stock during fiscal 2025.

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.

See “Proposal Two - Advisory Vote to Approve Executive Compensation — Compensation Discussion and Analysis — Highlights of 2025 Performance Related to Executive Compensation” for more information and Exhibit A for a reconciliation of the non-GAAP financial measures used in determining executive compensation to GAAP financial results.

Highlights of 2025 Executive Compensation

We design our executive compensation programs to target total compensation (and each principal element of compensation) for our NEOs at or about the 50th percentile of our customized peer group and size-adjusted survey sources. The principal elements of these compensation programs are base salary, annual performance-based cash bonus and long-term incentive compensation, including performance-based equity compensation. Additionally, our NEOs are covered under our broad-based employee benefit plans and executive severance plan. Ms. Zakas and Mr. McAndrew are subject to specific employment agreements and change-in-control severance agreements and do not receive benefits under the executive severance plan.

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 92% and 78% in each of the last two years, respectively.

PROXY STATEMENT FOR 2026 ANNUAL MEETING 11

PROXY SUMMARY

We structure a significant portion of executives’ total compensation as incentive/performance-based compensation.

•We set clear and measurable financial goals for Company performance.

•We assess progress toward strategic priorities when evaluating individual performance.

•We align executive compensation with shareholder value with performance metrics, including rTSR and ROIC.


CEO TOTAL TARGET COMPENSATION(1)						OTHER NEOs TOTAL TARGET COMPENSATION(1)

(1) Excludes Other Compensation. See "Proposal Two - Advisory Vote to Approve Executive Compensation — Executive Compensation Tables — Summary Compensation Table" for total compensation as earned.

Compensation for fiscal 2025 reflects Company performance.

•Our NEOs’ compensation was positively affected by performance in relation to targets set for fiscal 2025.

•Annual cash bonuses earned by Mses. Zakas and Rasmussen and Messrs. McAndrew, Heinrichs, Floyd and Helms were 199.0% of target.

•Long-term compensation based on rTSR is earned and vests as of the end of the applicable three-year cumulative performance period. Long-term compensation based on rTSR granted for the fiscal 2023 to fiscal 2025 performance period was earned at 198.7% of target.

•Long-term compensation based on ROIC is earned and vests as of the end of the applicable three-year cumulative performance period based on the three-year average ROIC performance of each year within the performance period. By way of example, the fiscal 2025 ROIC performance will be calculated by measuring the individual annual ROIC performance of fiscal 2025, fiscal 2026 and fiscal 2027 and dividing by three. Long-term compensation based on ROIC was first granted for fiscal 2023 (with a performance period from fiscal 2023 to fiscal 2025). Long-term compensation based on ROIC performance granted for fiscal 2023 was earned at 200% of target.

•Long-term compensation in the form of time-based restricted stock units and stock options awarded in fiscal 2025 vests annually over a three-year period.

We continue to maintain best practices for executive compensation.

•Our equity incentive plan prohibits the repricing or exchange of equity-based awards without stockholder approval.

•We prohibit hedging and pledging of our Common Stock by executives or directors.

•Our executives and directors are subject to stock ownership guidelines.

•We can “clawback” cash- or equity-based compensation paid to executives under certain circumstances.

•We do not provide excise tax gross-up benefits.

•We design our compensation programs to mitigate risk.

•We require a “double trigger” with respect to vesting of executive officers’ equity awards upon a change-in-control.

See “Proposal Two - Advisory Vote to Approve Executive Compensation — Compensation Discussion and Analysis — Executive Compensation Program Overview”, “— Other Factors Considered by the Compensation Committee” and “— Other Compensation Practices and Policies” for more information regarding our compensation philosophy, structure and developments.

ELECTION OF DIRECTORS


Proposal One
Election of Nine 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 well-rounded 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 composed 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 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 almost 15 years of distinguished service as a director on our Board, Mr. Thomas Hansen will retire at the 2026 Annual Meeting. Mr. Hansen has more than 30 years of experience in senior executive positions with multiple companies, including service as a Vice Chair, Executive Vice President, and General Manager. Mr. Hansen’s executive and operational experience have contributed significantly to the Company’s success. His retirement marks the end of a tenure that has laid the foundation for our continuing long-term success — one defined by steady leadership, sound judgment, and an unwavering commitment to excellence. Mr. Hansen has served on multiple Board committees, including as Chair of the Audit Committee. His integrity, intelligence, diligence, and attention to detail have consistently helped to strengthen our governance and financial oversight. Throughout his tenure, Mr. Hansen has always brought a thoughtful, broad perspective on business strategy, capital allocation, employee relations, and operations to the Board and management. We take this opportunity to thank Mr. Hansen for his many years of service, advice, wisdom, and dedication.

Marietta Edmunds Zakas has served as a Board member and CEO since August 2023. She also served as Executive Vice President and CFO from January 2018 to August 2023 and as Senior Vice President, Strategy, Corporate Development and Communications from November 2006 to December 2017. Throughout her career at Mueller, Ms. Zakas has been committed to the Company’s advancement and to the successful execution of our strategy in the interests of all our stakeholders. After many years of distinguished service, Ms. Zakas will retire from the Board and as CEO at the 2026 Annual Meeting. Her contributions to our success are innumerable. Her leadership and foresight have added immeasurable value throughout our organization and to all our stakeholders. We would like to take this opportunity to thank Ms. Zakas for all of her many years of service to the Company, the Board, and our stakeholders. See “Proposal Two

Board Refreshment/Board Succession Planning

We continued our refreshment program that has introduced eight new directors to the Board since 2019 and has seen the retirement of seven, including Mr. Hansen this year, of our longer-tenured members beginning in 2021. As part of this program, each member of the Board who has served for more than 10 years will have retired by the Annual Meeting. 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.

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.

Board Tenure Policy

The Board believes that an appropriate mix of tenured directors and newer directors with fresh perspectives is necessary to support a vital and effective Board. Complementing this strategy of refreshment and enhancement is a commitment to making the most of our longer-tenured directors’ experience and knowledge of the Company’s operations. While the Board believes the best interests of the Company are served by taking advantage of all available talent and that a significant degree of continuity year-over-year is beneficial to stockholders, it also believes that age and tenure are important considerations in assessing Board composition. Accordingly, in January 2024, the Board prospectively implemented tenure and age limits of 10 years and 75 years, respectively, and provided discretion to the Board to allow exceptions to these limits if such exceptions would be in the best interest of the Company.

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 2025, the number of Board members was nine. In fiscal 2026, with the retirement of Mr. Hansen and the addition of Mr. Sengstack, if elected, the number of our Board members will remain nine. Each of our director nominees is independent, except Mr. McAndrew. As demonstrated by the following key metrics, 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.

As of September 30, 2025

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. Set forth below is a summary of the key skills and experience that we have determined to be necessary for the Board as a whole. See “Proposal One - Election of Nine Directors — The Board of Directors” for information concerning each nominee’s relevant skills and experience.	Nomination Process At-a-Glance

ELECTION OF DIRECTORS


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. We recognize that an engaged and diverse workforce is the foundation of our success, so 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.

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. 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 assessments. 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 oversees the risk associated with the Company’s cybersecurity, artificial intelligence (“AI”) and data privacy programs and practices and consults with management regarding various related initiatives. The Audit Committee is also responsible for reviewing cyber, AI and data security matters, including cybersecurity and AI threat and risk mitigation initiatives. The Audit Committee requests that management report to the Audit Committee and/or the full Board regularly on its assessment not only of cybersecurity, 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.

The Board executes its risk oversight function both as a whole and through delegation to its committees(1), specifically:


Audit Committee •Oversees risk management related to accounting and financial reporting, the audit process, internal control over financial reporting and disclosure controls and procedures •Oversees the internal audit function •Monitors legal and compliance issues and matters •Reviews risks and risk mitigation initiatives associated with cybersecurity, AI, and data security matters			Compensation and Human Resources Committee •Oversees risk management related to the risks and rewards associated with our compensation policies and practices •Oversees management development and succession planning across senior positions
Environment, Health and Safety Committee •Oversees risk management related to risks directly related to the environment, health and safety areas			Nominating and Corporate Governance Committee •Oversees risk management related to governance structure and processes and risks arising from related person transactions

(1) The Board dissolved the Capital Allocation and Operations Committee as of October 1, 2025, and the subject matter addressed by this committee has been and will continue to be overseen by the Board.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE

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 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 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 (the “EHS Committee”) oversees matters related to the environmental, materials sustainability and employee health and safety programs.

•The 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, GHG emissions and solid waste management. The most current ESG Report may be found at https://www.muellerwaterproducts.com/environmental-social-and-governance. Neither our website nor the ESG Report is a part of, or incorporated by reference in, 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 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.

Listed below are some of the Board policies and other materials relating to our corporate governance program that are available on our website. We will also provide copies of any of these policies and materials without charge upon written request to our Corporate Secretary at Mueller Water Products, Inc., 1200 Abernathy Road, N.E., Suite 1200, Atlanta, Georgia 30328.

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 fiscal 2025, 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 engage with representatives of many of our top institutional stockholders to solicit feedback

PROXY STATEMENT FOR 2026 ANNUAL MEETING 31

ELECTION OF DIRECTORS

on performance, strategy, vision, risk management, governance 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 CEO is in the best interest of the Company and its stockholders. Mr. Van Arsdell currently serves as our Non-Executive Chair, and Mr. McAndrew will succeed our current CEO, Ms. Zakas, effective February 9, 2026.

Under our Bylaws, the Chair presides over meetings of the Board and of stockholders, while the CEO 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 New York Stock Exchange (“NYSE”) listing standards; and

•The Board must affirmatively determine the director otherwise has no material relationship with the Company 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. The information on our website is not a part of this Proxy Statement.

Each of our directors, other than our CEO, and each member of the Audit Committee, the Compensation Committee and the Governance Committee is independent pursuant to the above director qualification 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.

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 four standing committees: the Audit Committee, the Compensation Committee, the Governance Committee and the EHS Committee. An additional committee, the Executive Committee, meets as needed. Effective October 1, 2025, the Board dissolved the Capital Allocation and Operations Committee (the “Capital Allocation Committee”), which was formed in accordance with the October 2022 Cooperation Agreement entered into between the Company and Ancora Catalyst Institutional, LP and certain of its affiliates. Each member of the Audit, Compensation, Governance and EHS Committees satisfies both the NYSE’s and our definition 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

32 MUELLER WATER PRODUCTS, INC.

ELECTION OF DIRECTORS

Board designated each of Messrs. Hansen, Garcia, Healy and Karl Niclas Ytterdahl as an “audit committee financial expert” during 2025.

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 Executive Committee, Mr. Van Arsdell 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 5 meetings in fiscal 2025. Directors fully attended 100% of Board meetings and approximately 97% of the meetings of the Board’s committees in fiscal 2025. Although the Company does not have a formal policy requiring attendance at annual meetings of stockholders, directors are encouraged to attend. Each director nominated for election attended the 2025 Annual Meeting of Stockholders.

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 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.

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.

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 General Counsel 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 consistent with the interests of the Company and its stockholders. In addition, the Board has delegated to the Chair of the Governance Committee the authority to 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 2025, 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 [email protected], or with the Audit Committee by sending an email message to [email protected]. 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 “Proposal Two -

36 MUELLER WATER PRODUCTS, INC.

ELECTION OF DIRECTORS

Advisory Vote to Approve Executive Compensation — Compensation Discussion and Analysis — Executive Compensation Program Overview — Peer Group Benchmarking and Total Compensation.”

The Board reviews the Compensation Committee’s recommendations and approves 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 “Proposal Two - Advisory Vote to Approve Executive Compensation — 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 $110,000 in fiscal 2025. 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. Non-employee members of the Capital Allocation Committee received an annual retainer of $15,000, but the Board discontinued the $15,000 annual retainer effective February 6, 2025. Our Non-Executive Chair receives $100,000 for serving in this capacity. The annual retainers and chair fees are paid pro-rata quarterly.

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. Former Director Michael Tokarz was the only non-employee director who participated in this plan. Mr. Tokarz’s deferred payments were maintained in a stock equivalent account.

In January 2024, the Board terminated the Directors’ Deferred Fee Plan, approving the survival of the provisions necessary to address Mr. Tokarz’s settlement in January 2025 in the amount of $5,219,157.48.

Equity-Based Awards

Our 2006 Stock Incentive Plan, as amended (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 first day following the date on which he or she commences service as a director, the economic value and terms of which to be determined by the Compensation Committee. See “Proposal Two - Advisory Vote to Approve Executive Compensation — Compensation Discussion and Analysis — Other Compensation Practices and Policies — Role of Compensation Consultant in Compensation Decisions.”

On February 6, 2025, each non-employee director, with the exception of Ms. Terry and Mr. Weaver, received equity-based awards in the amount of $130,000, which resulted in the grant of 4,672 restricted stock units (“RSUs”) in accordance with the Stock Plan and related policies. On February 7, 2025, Ms. Terry and Mr. Weaver each received an initial grant of 4,758 RSUs following their election to the Board in accordance with the Stock Plan. These RSUs 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 6, 2025, in connection with their retirement from long-tenured service, Ms. Franklin and Dr. Thomas each received an equity-based award in the amount of $130,000, which resulted in the grant of 4,672 RSUs that vest in full on the first anniversary of the grant date.

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 50th percentile of our Peer Group and size-adjusted survey sources. 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 2025, incentive compensation represented approximately 84% of our current CEO’s total target compensation (excluding Other Compensation), and an average of approximately 73% 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 2025, produced a performance-based cash incentive compensation payout percentage of 199.0% of target for Mses. Zakas and Rasmussen and Messrs. McAndrew, Heinrichs, Floyd and Helms and a long-term incentive payout percentage of 198.7% for incentives based on rTSR and 200% for incentives based on ROIC 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.

Highlights of Fiscal 2025 Performance



	Focused on Operational Investment and Efficiencies to Increase Long-Term Stockholder Value
We generated net sales of $1,429.7 million, operating income of $260.6 million, net income of $191.7 million, adjusted earnings before interest tax depreciation and amortization (“EBITDA”) of $326.2 million, net income per diluted share of $1.22 (with adjusted net income per diluted share of $1.31) and $219.3 million net cash flow provided by operating activities (free cash flow of $172.0 million). Adjusted EBITDA, adjusted net income per diluted share and free cash flow 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 to GAAP measures.


	Dividend Benefits		Stockholder Value
•We paid stockholders a quarterly $0.067 per share dividend during fiscal 2025, an increase of approximately 4.7% from fiscal 2024. •We returned $41.9 million to our stockholders through dividends in fiscal 2025.		We repurchased $15 million of our outstanding Common Stock during fiscal 2025.

Highlights of 2025 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 2025. Our compensation programs continually evolve to incorporate stockholder feedback, market best practices, and performance and retention considerations. See Exhibit A for a reconciliation of the following non-GAAP financial measures used in determining executive compensation to GAAP financial results.

Highlights of 2025 Executive Compensation

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


			We tie our executives' compensation to Company performance.


For fiscal 2025, 54.5% of our current CEO’s total target compensation, and an average of 42.8% of the total target compensation of our other NEOs, could only be earned by meeting performance goals at target.						PERFORMANCE-BASED TOTAL TARGET COMPENSATION(1)

•Our NEOs’ compensation was positively affected by Company performance in relation to targets set for fiscal 2025.

•Annual cash bonuses earned by our NEOs for fiscal 2025 ranged from $473,851 to $2,038,676 compared with $377,533 to $1,664,562 last year. The bonuses for Ms. Rasmussen and Mr. Heinrichs, who both performed the CFO role during fiscal 2025, were combined for the purposes of this calculation.

•Long-term performance-based compensation based upon rTSR was paid at 198.7% of target for fiscal 2025 compared with a rTSR payout at 144.2% of target last year.

•Long-term performance-based compensation based upon ROIC was paid at 200% of target for fiscal 2025. Long-term performance-based compensation based upon ROIC was first granted for fiscal 2023 (with a performance period from fiscal 2023 to fiscal 2025).


			We structure performance-based compensation to pay for performance.

Our Executive Compensation Guiding Principles focus explicitly on performance-based compensation and aligning pay for performance (see following page). 54.5% of our CEO and 42.8% of our NEO’s Target Total Direct Compensation is

performance-based. 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 2024 and 2025 annual meetings of stockholders, approximately 78% 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

•Based on the stockholder support expressed for our executive compensation programs, the Compensation Committee applied a consistent pay-for-performance philosophy in structuring executive compensation for fiscal 2025.

•Stockholders are invited to express their views or concerns on executive compensation directly to the Chair of the Compensation Committee in the manner described under “Corporate Governance — Communicating with the Board.”


			We utilize best practices for 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:


Stockholder Alignment •Ensure executives’ realizable wealth is significantly impacted by the value of Common Stock •Enable all management the opportunity to own stock in the Company to create an ownership mindset •Require executives to hold a meaningful Common Stock ownership amount •Emphasize and appropriately balance short- and long-term performance						Differentiate Pay Based on Performance and Value •Differentiate compensation in a way that recognizes the value that each person contributes both individually and collectively with other Company executives to attract and retain talent •Compensate based upon individual skills, experience, role and value to the Company •Measure performance based upon overall Company and individual contributions •Hold executives accountable for short-term incentive performance and long-term incentive performance of the Company

PROXY STATEMENT FOR 2026 ANNUAL MEETING 43

EXECUTIVE COMPENSATION


Market Competitiveness •Develop comparator groups based on the Company’s unique requirements for a blend of core industrial and technologically advanced products, general industry skills and in recognition of where we source and lose talent •Use different comparator groups based upon the required skills for each position type and level •Use external competitive market data to inform, not dictate, our compensation decisions						Pay Positioning, Pay Mix, and Award Realization •Evaluate Total Direct Compensation (TDC, i.e., salary, annual incentives, and long-term incentives) based on both internal and external market comparisons •Utilize Total Remuneration (TDC plus benefits and perquisites) to provide Company executives a competitive (median) market-based package •Balance TDC in a way that emphasizes both cash and equity ownership •Emphasize at-risk compensation (i.e., performance-based incentives) for executives

PEER GROUP BENCHMARKING AND TOTAL COMPENSATION

Each year, the Compensation Committee’s compensation consultant collects Peer Group compensation data, as well as survey data from multiple leading providers and prepares an executive benchmarking study using a market 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 comprehensive review focuses on companies that have similar industries for the Company’s talent market, relevant and appropriate size and business model screening criteria (e.g., well-managed companies; water, fluid, and flow control products manufacturers; municipality, utility, residential and non-residential construction customer base; and technology-leaning organizations), 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 2025, the Compensation Committee made no changes to the previous year’s group. The Peer Group for fiscal 2025 consisted of the companies listed below.


Fiscal 2025 Peer Group		The Compensation Committee targets total compensation at or about the 50th percentile of the Peer Group and size-adjusted survey sources
Advanced Drainage Systems, Inc.	Helios Technologies, Inc.
Badger Meter, Inc.	IDEX Corporation

Enerpac Tool Group Corp.	Lindsay Corporation
EnPro Industries, Inc.	Valmont Industries, 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 and the size-adjusted survey sources. The Compensation Committee targets total compensation at or about the 50th percentile of the Peer Group and size-adjusted survey sources, subject to individual adjustments based on experience, length of service, individual performance and other factors deemed appropriate by the Compensation Committee.

For fiscal 2026, the Compensation Committee, with input from its independent compensation consultant, reviewed and updated our peer group to ensure that it remains reflective of our talent market, relevant and appropriate size, and business model screening criteria. The Compensation Committee adopted a revised peer group of 19 companies, which removes three companies, including Chart Industries, Columbus McKinnon and Helios Technologies, that fail screening criteria related to market premiums, total shareholder return and return on invested capital. The revised peer group adds three companies that better align with the Company’s size and financial performance requirements, including Flowserve Corporation, A.O. Smith Corporation and AAON, Inc. The revised peer group will be used in making compensation decisions with respect to fiscal 2026.

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 50th percentile of comparable executives in the Peer Group and size-adjusted survey sources. Based on actual achieved performance against performance goals, each NEO may earn between 0% and 200% of her or his annual cash target opportunity. For fiscal 2025, the Compensation Committee selected two types of performance metrics: (i) financial goals (weighted 90%) and (ii) ESG-related performance metrics (weighted 10%). The financial goals related to adjusted EBITDA, adjusted working capital (as a % of adjusted net sales) and adjusted 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 ESG-related performance metric was tied to reductions in total recordable incidence rates and key performance indicators for sustainability, including reduction of GHG intensity and water withdrawal, and specific activities identified as leading safety indicators. The Compensation Committee selected these metrics because they promote, drive and support the Company’s ESG initiatives and performance. All financial performance goals were set with minimum (or threshold), target and maximum objectives for each goal as described in the “2025 Annual 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 2025 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 2025, the Compensation Committee set each NEO’s target long-term compensation value at or about the 50th percentile of comparable executives in the Peer Group and size-adjusted survey sources.

For fiscal 2025, fiscal 2024 and fiscal 2023, 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 PRSUs are based 50% on rTSR performance ("Market Units") and 50% on ROIC (“ROIC Units”).

PERFORMANCE-BASED RESTRICTED STOCK UNITS

The following are the key aspects of the PRSUs awarded, granted, earned and/or vested in fiscal 2023, fiscal 2024 and fiscal 2025:

•For each of fiscal 2023, fiscal 2024 and fiscal 2025, 50% of each NEO’s target long-term incentive compensation value was awarded in PRSUs. The number of PRSUs awarded was equal to the target value divided by the share price of our Common Stock on the date of award. As noted above, the PRSUs comprise 50% Market Units and 50% ROIC Units.

•Market Units:

◦The 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 percentile 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 3-year award period, the Compensation Committee confirms actual performance against the applicable performance target.

PROXY STATEMENT FOR 2026 ANNUAL MEETING 47

EXECUTIVE COMPENSATION

◦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.

•ROIC Units:

◦ROIC Units consist of a single tranche and vest on a 3-year cumulative performance period.

◦The Compensation Committee establishes a ROIC Unit performance target for the performance period on the grant date of the award.

◦At the conclusion of the performance period, the performance achieved each year during the performance period is averaged for a final achievement amount.

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

•PRSUs Generally:

◦All PRSUs are settled in shares of Common Stock.

◦To receive shares of Common Stock in settlement of PRSUs, the NEO must normally be employed through the last day of the 3-year award cycle.

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

PERFORMANCE MEASURES AND RESULTS FOR FISCAL 2025

The applicable performance targets for the performance period for PRSUs awarded for fiscal 2023 (vested September 30, 2025), fiscal 2024 (vesting September 30, 2026) and fiscal 2025 (vesting September 30, 2027) were each based on 50% rTSR and 50% ROIC performance.

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 an independent compensation consultant. For fiscal 2023, fiscal 2024 and fiscal 2025 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. For the fiscal 2023 Market Unit grant, the performance during the actual performance period resulted in a Company rTSR in the 74th percentile, resulting in an achievement of 198.7%.

The Compensation Committee determined the ROIC target using benchmark data from the Peer Group and assistance from the Company’s independent compensation consultant. “ROIC” is defined for this purpose as the quotient obtained by dividing the Adjusted Return by Invested Capital. “Adjusted Return” means the net operating profit after tax, which is the adjusted operating income multiplied by (one minus the Company’s effective tax rate)1, excluding charges relating to: strategic reorganization and other charges, non-cash impairments, legal settlements, severance, product liability charges, one-time impact of significant and/or retroactive tax law changes if not contemplated in the ROIC target, other adjustments to conform to adjustments in earnings release, and any other adjustment approved by the Compensation Committee. “Invested Capital” means total assets less liabilities, excluding cash and debt, with average of five quarter-end balances for each year for invested capital. For fiscal 2025 awards, vesting at the end of fiscal 2027, the performance necessary to earn at least 50% of ROIC Unit target payout requires annual ROIC of 12.50%, the performance necessary to earn 100% of ROIC Unit target payout requires ROIC of 14.50%, and the performance necessary to earn the maximum 200% of ROIC Unit target payout requires ROIC of at least 17.00%. For fiscal 2024 awards, vesting at the end of fiscal 2026, the performance necessary to earn at least 50% of ROIC Unit target payout requires annual ROIC of 9.50%, the performance necessary to earn 100% of ROIC Unit target payout requires ROIC of 11.25%, and the performance necessary to earn the maximum 200% of ROIC Unit target payout requires ROIC of at least 13.50%. For fiscal 2023 awards, which vested at the end of fiscal 2025, the performance necessary to earn at least 50% of ROIC Unit target payout required annual ROIC of 9.50%, the performance necessary to earn 100% of ROIC Unit target payout required ROIC of 11.25%, and the performance necessary to earn the maximum 200% of ROIC Unit target payout required ROIC of at least 13.50%. Actual ROIC performance for the fiscal 2023 awards’ fiscal 2025 performance period was 21.48%. Actual ROIC performance for the fiscal 2023 awards’ fiscal 2024 performance period was 16.60%. Actual ROIC performance for the fiscal 2023 awards’ fiscal 2023 performance period was 11.11%. Accordingly, the average ROIC performance over the fiscal 2023 awards

performance period was 16.40%, with the achievement amount equal to 200% of the target. See “Executive Compensation Tables — Grants of Plan-Based Awards Table” for additional information.

TIME-BASED RESTRICTED STOCK UNITS

For fiscal 2025, 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 Tables — Grants of Plan-Based Awards Table.”

TIME-BASED STOCK OPTIONS

For fiscal 2025, 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. Normally, one-third of the stock options awarded vest on each anniversary of the award date subject to continuing service. Due to the rules for how the grant date fair value of long-term incentive awards must be calculated for accounting purposes, the 2025 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 2025 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 10 to our consolidated financial statements in our Annual Report on Form 10-K for the year ended September 30, 2025.

value actually received upon exercise of options by the NEOs in fiscal 2025, refer to our Annual Report on 2025 Option Exercises and Stock Vested table in this Proxy Statement. Outstanding option awards are reflected in the 2025 Outstanding Equity Awards table in this Proxy Statement. Also see the “Executive Compensation Tables — 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 last regularly scheduled meeting of the calendar 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. 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. The Compensation Committee does not take material nonpublic information into account when determining the timing and terms of such awards, and the Company’s release of material nonpublic information is not timed with the purpose of affecting the value of executive compensation.

LEADERSHIP TRANSITION COMPENSATION MATTERS

In November 2025, the independent members of our Board, upon the recommendation of our Compensation Committee, with assistance from independent advisors, entered into agreements addressing the compensation for Ms. Zakas and Mr. McAndrew in each of their new roles of Senior Advisor and President and CEO, respectively.

2025 LEADERSHIP TRANSITIONS AND AWARDS

In connection with Mr. McAndrew’s appointment as President and CEO, effective as of the Transition Date, Mr. McAndrew will receive an annual base salary of $915,000, a target annual bonus opportunity for fiscal year 2026 equal to 100% of his base salary (pro-rated as of the Transition Date) and a target long-term incentive opportunity equal to 370% of Mr. McAndrew’s base salary, minus the long-term incentive opportunity granted to Mr. McAndrew in December 2025 (the “2026 LTI Grant”). The 2026 LTI Grant will be granted in the form of stock options (25%), RSUs (25%) and PRSUs (50%). The stock options and restricted stock units will vest ratably over a three-year period. The PRSUs will be subject to the same performance cycle and criteria as the PRSUs granted to Mr. McAndrew in December 2025.

In connection with Ms. Zakas’ transition to Senior Advisor on the Transition Date, she will be paid her current base salary, pro-rated from the Transition Date to December 31, 2026 (“Transition Period”). Additionally, Ms. Zakas will receive the following payments and benefits: (i) a prorated annual bonus for fiscal year 2026, determined based on the greater of target and actual performance, (ii) a reduced fiscal year 2026 equity award, to be granted as performance-based restricted stock units with a grant date value of $2,000,000, (iii) COBRA continuation coverage with monthly payments equal to 150% of the applicable monthly COBRA rate for the first 12 months of coverage (which coverage may be extended for an additional 24 month period at Ms. Zakas’ expense), (iv) continued group life insurance coverage through June 30, 2028, (v) reimbursement for financial planning services of up to $20,000 and (vi) reimbursement for up to $25,000 in legal fees. Ms. Zakas’ equity outstanding awards will remain eligible to vest during the Transition Period pursuant to the terms of the applicable incentive plans and award agreements.

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.

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 2025 on the same basis as our other eligible employees, under which we make matching contributions in accordance with the terms of that plan.

PROXY STATEMENT FOR 2026 ANNUAL MEETING 51

EXECUTIVE COMPENSATION

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 2025, the Compensation Committee offered each of the NEOs limited perquisites, including a car allowance (excluding Ms. Rasmussen and Messrs. Helms and Floyd), life insurance, supplemental long-term disability insurance and reimbursement for certain financial planning and annual physical examination expenses. See “Executive Compensation Tables — Summary Compensation Table - All Other Compensation.”

SEVERANCE BENEFITS

Each NEO is entitled to severance benefits. See “Executive Compensation Tables — 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 in connection with a change-in-control (as defined in the agreements) 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 terminated by the Company without Cause or the executive resigns with Good Reason (as such terms are 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 applicable agreement, 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.

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. During fiscal 2025, Ms. Rasmussen and Messrs. Heinrichs and Floyd were the only NEOs who participated in the ESPP.

HEALTH AND WELFARE BENEFITS

We generally offer group medical, dental, vision, life and long-term disability insurance in a flexible benefits package to all active U.S. employees, except as otherwise required by collective bargaining agreements. Employees are provided life insurance up to one times their base salaries at no charge to the employee, other than related income taxes. For an additional charge, employees may obtain coverage of up to four times their base salary up to a maximum life insurance benefit of $1,250,000. NEOs participate in our benefit packages on the same basis as other eligible employees.

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 independent 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 clawback policies.

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 2025, the Compensation Committee retained Farient Advisors, LLC as its compensation consultant. The Compensation Committee reviews the performance of its compensation consultant annually.

In fiscal 2025, 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 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

PROXY STATEMENT FOR 2026 ANNUAL MEETING 53

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 CEO discuss the financial metrics and operational goals intended to closely align performance targets of the Company with our strategic goals. The CEO makes recommendations to the Compensation Committee for executives other than herself or 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 CEO’s recommendations.

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

In fiscal 2025, the CEO 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 her 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 for certain qualifying performance-based compensation existing on November 2, 2017), 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, except to the extent the transition rule applies. In fiscal 2025 and in plans for fiscal 2025, the Compensation Committee continued to design compensation programs and make grants that it believes are performance-based and aligned with the interests of our stockholders.

COMPENSATION RECOVERY (CLAWBACK) POLICIES

The Compensation Committee adopted, effective October 2, 2023, a revised Incentive Compensation Recovery Policy (the “Incentive Clawback Policy”) in compliance with Exchange Act Rule 10D and corresponding NYSE listing standards that applies to the Company’s current and certain former executive officers. In the event the Company is required to restate its financial statements as a result of events described in the NYSE listing standards, the Compensation Committee is authorized to recover incentive compensation awarded to covered current and former executive officers of the Company in accordance with the Incentive Clawback Policy. The Compensation Committee has exclusive authority to administer and enforce the provisions of the Incentive Clawback Policy. This Incentive Clawback Policy reflects the Company’s culture, which emphasizes high standards of integrity and reinforces the Company’s pay-for-performance compensation philosophy.

In addition, the Compensation Committee adopted, effective December 3, 2024, a Supplemental Compensation Recovery Policy (the “Supplemental Clawback Policy”) that provides the Compensation Committee the discretion to recoup incentive compensation in all forms, including time-and performance-based awards received by a current or former Vice President, Senior Vice President, Executive Vice President, President/CEO or other Executive Officer (“Covered Employee”) during the three-year period prior to which the Board or the Compensation Committee determines that Detrimental Conduct (as defined below) has occurred. “Detrimental Conduct” occurs when a Covered Employee engages in conduct that constitutes (a) gross negligence (including gross negligence in supervising the work of others), (b) fraud, or (c) intentional

54 MUELLER WATER PRODUCTS, INC.

EXECUTIVE COMPENSATION

misconduct. The Supplemental Clawback Policy applies to incentive compensation granted after adoption of the policy, beginning with our fiscal 2025 incentive awards.

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 our Common Stock by executives or directors.

INSIDER TRADING POLICY

We have adopted an insider trading policy that governs the purchase, sale and/or other dispositions of our securities by directors, officers and employees, as well as the Company, that is reasonably designed to promote compliance with insider trading laws, rules and regulations, and the New York Stock Exchange listing standards applicable to us. A copy of our Insider Trading Policy is filed as Exhibit 19.1 to our Annual Report on Form 10-K.

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		6x base salary
President		4x base salary
Executive Vice Presidents		3x base salary
Senior Vice Presidents		2x base salary
Vice Presidents		1x base salary
Non-Employee Directors		5x annual retainer

In general, participants have five (5) years from the date of becoming subject to the program to achieve the applicable stock ownership target. If a participating individual is promoted, such participant has three (3) years from the date of promotion to increase his or her holdings to meet the applicable stock ownership requirements. All current executive officers and directors are in compliance with our stock ownership guidelines. Our stock ownership guidelines are available on our website at www.muellerwaterproducts.com. The information on our website is not a part of this Proxy Statement.

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.

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. In connection with her hiring, Ms. Rasmussen received an initial sign-on bonus RSU award in the amount of $750,000, which vests in equal installments on the first, second and third anniversaries of the award date, subject to Ms. Rasmussen’s continued employment through such vesting dates.

(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 2025, i.e., Market Units, assuming achievement of threshold, target and maximum performance. See “Compensation Discussion and Analysis — Compensation Elements — Long-Term Equity-Based Compensation — Performance-Based Restricted Stock Units” for more information.

(4)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 ROIC performance goals established in fiscal 2025, i.e., ROIC Units, assuming achievement of threshold, target and maximum performance. See “Compensation Discussion and Analysis — Compensation Elements — Long-Term Equity-Based Compensation — Performance-Based Restricted Stock Units” for more information.

(5)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 generally 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 dates are ten years from the applicable grant dates. 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.

(6)Each stock option granted during fiscal 2025 was granted with a per-share exercise price equal to the closing price of our Common Stock on the NYSE on the award date.

(7)See footnotes 3 and 4 to the “Summary Compensation Table” for a description of the methods used to determine grant date fair value of equity-based awards.

EXECUTIVE COMPENSATION

Employment, Severance and Change-in-Control Arrangements

At September 30, 2025, we maintained employment agreements with each NEO except as noted in the footnotes to the below table. 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) (%)
Marietta Edmunds Zakas	947,250	110	2,000	4 weeks	300.0
Paul McAndrew	582,400	75	2,000	4 weeks	262.5
Melissa Rasmussen(4)	550,000	70	N/A	4 weeks	150.0
Todd P. Helms(4)	400,794	60	N/A	4 weeks	100.0
Scott P. Floyd(4)	426,969	60	N/A	5 weeks	100.0

(1)Salaries are reviewed annually. Amounts shown represent annual salary rates as of September 30, 2025.

(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 18 months for each NEO, together with a lump sum payment of unpaid salary and other benefits.

(4)Ms. Rasmussen and Messrs. Helms and Floyd are subject to the Company's executive severance plan and do not maintain separate employment agreements. The executive severance plan provides for lump sum payments for most severance benefits.

At September 30, 2025, we also maintained change-in-control arrangements with Ms. Zakas and Mr. McAndrew. Under the change-in-control agreements with Ms. Zakas and Mr. McAndrew, if a change-in-control (as defined in the agreements) of the Company occurs and the executive’s employment is terminated by the Company without Cause (as defined in the agreements) or the executive resigns for Good Reason (as defined in the agreements) within 24 months (a “Qualifying Termination”), all outstanding equity awards would immediately vest. However, if any equity awards subject to the change-in-control agreements are not continued or replaced with similar awards upon the occurrence of a change-in-control, such awards would vest upon a change-in-control, and any such performance equity awards would be deemed earned at target. 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. Further, following a Qualifying Termination, the executive would be entitled to a lump-sum severance payment equivalent to 3.0x (for Ms. Zakas) and 2.0x (for Mr. McAndrew) 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 payment of 150% of the cost of elected COBRA coverage for 18 months. The agreements also contain a “best-of-net” provision, so that, in the event excise taxes would be imposed on payments under the applicable agreement, 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 her or him on an after-tax basis.

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, each as defined in the agreements) 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 1.5x and 1.0x the sum of base salary and annual target incentive bonus for Ms. Rasmussen and Messrs. Helms and Floyd, respectively, a pro rata amount of her or 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, other than Mr. Heinrichs, whose separation of service occurred on September 30, 2025, 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 she or he terminates employment without Good Reason or is terminated for Cause, except as otherwise noted. 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 applicable NEO’s employment had terminated on September 30, 2025.

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 or resignation with Good Reason after a change-in-control

C - Death, disability or Retirement with notice after achieving Retirement eligibility

D - Retirement without notice

(1)Each current NEO 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, 2025, and represent bonus paid at target except for Ms. Zakas and Mr. McAndrew, whose pro rata bonuses are calculated based on actual performance against performance goals as specified by the terms of the December 4, 2024, letter agreement with Ms. Zakas and Mr. McAndrew’s August 21, 2023, employment agreement.

(2)The value of stock options is the difference between the closing price of Common Stock on September 30, 2025, the last trading day of the fiscal year, 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, 2025, multiplied by the number of RSUs. The value of PRSUs reflects payout at target for future performance periods within the award cycle. The closing price of our Common Stock on September 30, 2025 on the NYSE was $25.52.

(3)For Ms. Zakas and Mr. McAndrew, health and welfare benefits are continued for up to 42 months from the separation date based on the current elections and plan terms depending upon the scenario. For Ms. Rasmussen and Messrs. Helms and Floyd, each NEO receives a lump sum amount equal to the applicable monthly contribution for health and welfare benefits multiplied by 18, 12 and 12, respectively.

PROXY STATEMENT FOR 2026 ANNUAL MEETING 63

EXECUTIVE COMPENSATION

(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 Ms. Zakas and Mr. McAndrew or $25,000 for Ms. Rasmussen and Messrs. Helms and Floyd.

(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 Ms. Zakas is 300%. The percentage applicable to Mr. McAndrew is 262.5%. The percentage applicable to Ms. Rasmussen is 150% plus an amount equal to a pro rata annual incentive bonus calculated at target goals as shown in the Bonus Earned as of Event Date column. The percentage applicable to Messrs. Helms and Floyd is 100% plus an amount equal to a pro rata annual incentive bonus calculated at target goals as shown in the Bonus Earned as of Event Date column. Other severance benefits, if applicable, are paid in monthly installments over 18 months, together with a lump sum payment of unpaid salary and other benefits.

(6)Cash severance in Case B (change-in-control termination) for Ms. Zakas is equal to three times the sum of annual base salary plus 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 Mr. McAndrew 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 Ms. Rasmussen is equal to one and a half times annual base salary and target annual incentive bonus plus pro rata target annual incentive bonus, accrued vacation and ancillary medical benefits. Cash severance in Case B (change-in-control termination) for Messrs. Helms and Floyd 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.

(2)Amounts reflect the total compensation for our NEOs, as reported in the Summary Compensation Table for each applicable year.

(3)In accordance with Item 402(v) of Regulation S-K, the fair values of unvested and outstanding equity awards were remeasured as of the end of each fiscal year, and as of each vesting date, during the years displayed in the tables below. For PRSUs with an rTSR metric, or Market Units, the fair values as of each measurement date (prior to the end of the performance period) were determined using a Monte Carlo simulation pricing model, with assumptions and methodologies that are generally consistent with those used to estimate fair value at grant under GAAP. The range of estimates used in the Monte Carlo calculations are as follows: (i) for 2025, volatility between 32.8% and 36.8% and risk-free rate between 3.5% and 3.6%; (ii) for 2024, volatility between 28.3% and 29.2% and risk-free rate between 3.6% and 3.9%; (iii) for 2023, volatility between 30.0% and 30.8% and risk-free rate between 4.9% and 5.3%;

(iv) for 2022, volatility between 29.4% and 31.3% and risk-free rate between 4.0% and 4.1%; and (v) for 2021, volatility between 27.3% and 41.3% and risk-free rate between 0.1% and 0.3%. For PRSUs with a Return on Net Assets metric, fair values reflect the probable outcome of the performance vesting conditions as of each measurement date. For a discussion of the assumptions made in the valuation at grant, see Note 10 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for fiscal 2025. For each fiscal year reflected, the “compensation actually paid” to the PEOs and the average “compensation actually paid” to the non-PEO NEOs reflect the following adjustments made to the total compensation amounts reported in the Summary Compensation Table for each applicable fiscal year, computed in accordance with Item 402(v) of Regulation S-K:

(4)Company TSR and Peer Group TSR reflected in these columns for each applicable fiscal year are calculated based on a fixed investment of $100 at the applicable measurement point on the same cumulative basis as is used in Item 201(e) of Regulation S-K. Peer Group TSR for each applicable fiscal year uses the Dow Jones U.S. Building Materials & Fixtures Index as disclosed in our annual report on Form 10-K for fiscal year ended 2025 pursuant to Item 201(e) of Regulation S-K. Historical stock performance is not necessarily indicative of future stock performance.

(5)Amounts reflect net income calculated in accordance with GAAP as reported in our audited financial statements for the applicable fiscal year.

(6)While we use numerous financial and non-financial performance measures to evaluate performance under our compensation programs, Adjusted EBITDA is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used to link compensation actually paid to NEOs, for the most recently completed fiscal year, to Company performance.

Relationship Between Pay and Performance

In accordance with Item 402(v) of Regulation S-K, we are providing the following charts to show graphically the relationship between “compensation actually paid” (“CAP”) to our NEOs and (i) our cumulative TSR (“MWA TSR”) and our

Tabular List of Financial Performance Measures

As also required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, the following table lists the three financial performance measures that, in the Company’s assessment, represent the most important performance measures used to link CAP for our NEOs to Company performance for fiscal 2024. The performance measures included in this table are not ranked by relative importance.


Adjusted EBITDA
Adjusted Net Sales
Free Cash Flow

In addition to these financial metrics, the Company’s executive compensation program is impacted by our performance with respect to ESG goals under the annual cash incentive program. Our ESG goals are included as an element of our annual cash incentive program because they collectively represent ESG criteria that are priorities for the Company. Please see the “Compensation Discussion and Analysis — Compensation Elements — Annual Cash Incentive Awards” section for further information regarding these financial performance measures as well as the ESG goals used in our annual cash incentive program.

CEO Pay Ratio Disclosure

For fiscal 2025, (i) the annual total compensation of our median employee (excluding our current CEO) was $71,239 and (ii) the annualized total compensation of our current CEO was $6,855,283. Based on this information, the ratio of the annual total compensation of our CEO to that of the median employee is approximately 96 to 1. Our employee population consists of approximately 3,500 employees located throughout the world, with approximately 84% in the United States.

To identify the median employee for fiscal 2025, we included all part-time and full-time employees that were employed for any portion of fiscal 2025 so long as they were still actively employed on September 30, 2025. 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.

RATIFICATION OF THE APPOINTMENT OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


Proposal Three
Ratification of the Appointment of Our Independent Registered Public Accounting Firm for Fiscal 2026
			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, 2026, 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.

See below for a description of the fees EY billed us for fiscal 2025 and fiscal 2024.

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.

Fees and Services of the Independent Registered Public Accounting Firm

The Audit Committee appointed EY as the independent registered public accounting firm to audit our consolidated financial statements and internal control over financial reporting for fiscal 2025.

Audit Fees and Other Fees

The following table shows the approximate fees for audit and other services provided by EY for fiscal years 2025 and 2024 (in millions). All fees in 2025 and 2024 were pre-approved by the Audit Committee.

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 SEC rules on auditor independence and whether the independent registered public

68 MUELLER WATER PRODUCTS, INC.

RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

accounting firm is able to provide the most effective service. Audit and non-audit fees to be incurred by the independent registered public accounting firm for services permitted by the Sarbanes-Oxley Act of 2002 to be performed by such firm must be approved in advance by the Audit Committee Chair or another designated member of the Audit Committee for individual projects in amounts up to $150,000, and the Audit Committee must approve all such services for individual projects in amounts greater than $150,000. The Audit Committee periodically monitors the services rendered and actual fees paid to the independent registered public accounting firm to ensure the services are within the parameters approved by the Audit Committee.

Report of the Audit Committee

Committee Composition and Skills

The Audit Committee is composed of three independent directors meeting the requirements of applicable SEC and NYSE rules. The Board has determined all Audit Committee members are “financially literate” for purposes of the NYSE Listed Company Manual and select members qualify as audit committee “financial experts” within the meaning of the rules and regulations of the SEC. See “Proposal One - Election of Nine Directors — The Board of Directors” for a description of the business background of each member. No member of the Audit Committee serves on the audit committee of more than three public companies.

Meetings

The Audit Committee met 11 times during fiscal 2025, including 6 times by video/teleconference. Meetings include periodic executive sessions with the independent registered public accounting firm, internal auditors and management.

Responsibilities of the Audit Committee, Management and the Independent Auditor

The Audit Committee’s key responsibilities are set forth in its charter, which was approved by the Board and is available on our website at www.muellerwaterproducts.com. The information on our website is not a part of this Proxy Statement. See “Proposal One - Election of Nine Directors — Board Structure — Board Committee Information” for more information concerning the Audit Committee and its responsibilities. With respect to the Company's consolidated financial statements for fiscal 2025 and internal control over financial reporting:

•Management was responsible for preparing the financial statements and establishing and maintaining effective internal control over financial reporting. The Audit Committee was responsible for monitoring and overseeing the financial reporting and audit functions, as well as the internal control over financial reporting and disclosure.

•EY, the independent registered public accounting firm for fiscal 2025, was responsible for performing an independent audit of the Company’s consolidated financial statements and expressing an opinion on the conformity of those financial statements with accounting principles generally accepted in the United States and was also responsible for performing an independent audit of, and expressing an opinion on, the Company’s internal control over financial reporting.

•The Audit Committee reviewed and discussed with management and EY the audited consolidated financial statements for the year ended September 30, 2025, the quarterly consolidated financial statements and operating results for each quarter in the fiscal year and the related significant accounting and disclosure issues, the Critical Audit Matters (“CAMs”) and the effectiveness of internal control over financial reporting.

•The Audit Committee reviewed management’s report contained in the annual report on Form 10-K for the year ended September 30, 2025 (“Annual Report”), as well as EY’s Reports of the Independent Registered Public Accounting Firm included in the Annual Report related to its audits of the consolidated financial statements and internal control over financial reporting.

•The Audit Committee discussed with EY matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. In addition, EY provided the Audit Committee with the written disclosures and the letter required by the applicable requirements of the Public Company Accounting Oversight Board regarding EY’s communications with the Audit Committee concerning independence, and the Audit Committee has discussed with EY the firm’s independence.

BENEFICIAL OWNERSHIP OF COMMON STOCK

(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)The beneficial ownership reported in the table assumes each grantee of an award on February 6, 2025 or February 7, 2025, as applicable, will remain in continuous service through the first anniversary of the applicable grant date, and/or all awards granted on February 6, 2025 or February 7 2025 will vest on or before the first anniversary of the applicable grant date.

(4)As reported on Schedule 13G/A filed with the SEC on April 3, 2025, BlackRock, Inc. has sole investment discretion with respect to 25,289,723 shares and sole voting power with respect to 25,107,053 shares.

(5)As reported on Schedule 13G/A filed with the SEC on April 30, 2025, The Vanguard Group, Inc. has sole investment discretion with respect to 19,442,188 shares, shared voting power with respect to 182,685 shares and shared investment discretion with respect to 352,784 shares.

(6)As reported on Schedule 13G/A filed with the SEC on January 27, 2025, Franklin Mutual Advisers, LLC has sole investment discretion with respect to 7,119,780 shares and sole voting power with respect to 6,701,617 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 our executive officers and directors, we believe our Reporting Persons complied with all Section 16 filing requirements during fiscal 2025, with the exception of two filings for Richelle Feyerherm due to difficulty obtaining EDGAR filing codes: one Form 3 filing to report beneficial ownership and one Form 4 filing in connection with the grant of an equity award.

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 Marietta Edmunds Zakas, Chason A. Carroll and Barbara Smucygz 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

74 MUELLER WATER PRODUCTS, INC.

QUESTIONS ABOUT VOTING AND THE ANNUAL MEETING

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 [email protected] 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 9, 2026.

How can I ask questions pertinent to meeting matters?

Stockholders may submit questions either before the annual meeting (beginning February 3, 2026) or during the Annual Meeting. If you wish to submit a question either before or during the meeting, please log into meetnow.global/MU9QMJT 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.

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

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.
