Where Intelligence Meets Infrastructure® Investor Presentation February & March 2023

2 Non-GAAP Financial Measures In an effort to provide investors with additional information regarding the Company’s results as determined by accounting principles generally accepted in the United States (“GAAP”), the Company also provides non-GAAP information that management believes is useful to investors. These non-GAAP measures have limitations as analytical tools, and securities analysts, investors and other interested parties should not consider any of these non-GAAP measures in isolation or as a substitute for analysis of the Company’s results as reported under GAAP. These non-GAAP measures may not be comparable to similarly titled measures used by other companies. The Company presents adjusted net income, adjusted net income per diluted share, adjusted operating income, adjusted operating margin, adjusted EBITDA and adjusted EBITDA margin as performance measures because management uses these measures to evaluate the Company’s underlying performance on a consistent basis across periods and to make 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. The Company presents net debt and net debt leverage as performance measures because management uses them to evaluate its capital management and its financial position, and the investment community commonly uses them as measures of indebtedness. The Company presents free cash flow to assist management and investors in analyzing the Company’s ability to generate liquidity from its operating activities. The calculations of these non-GAAP measures and reconciliations to GAAP results are included as an attachment to this presentation, which has been posted online at www.muellerwaterproducts.com. The Company does not reconcile forward-looking non-GAAP measures to the comparable GAAP measures, as permitted by Regulation S-K, as certain items, e.g., expenses related to corporate development activities, transactions, pension expenses/(benefits) and corporate restructuring, may have not yet occurred, are out of the Company’s control and/or cannot be reasonably predicted without unreasonable efforts. Additionally, such reconciliation would imply a degree of precision and certainty regarding relevant items that may be confusing to investors. Such items could have a substantial impact on GAAP measures of the Company's financial performance.

3 Forward-Looking Statements This presentation contains certain statements that may be deemed “forward-looking statements” within the meaning of the federal securities laws. All statements that address activities, events or developments that the Company intends, expects, plans, projects, believes or anticipates will or may occur in the future are forward- looking statements, including, without limitation, statements regarding outlooks, projections, forecasts, expectations, commitments, trend descriptions and the ability to capitalize on trends, value creation, Board and committee composition plans, long-term strategies and the execution or acceleration thereof, operational improvements and excellence, the benefits of capital investments, financial or operating performance including improving sales growth and driving increased margins, capital allocation and growth strategy plans, positioning the Company’s product portfolio and the demand for the Company’s products. Forward-looking statements are based on certain assumptions and assessments made by the Company in light of the Company’s experience and perception of historical trends, current conditions and expected future developments. Actual results and the timing of events may differ materially from those contemplated by the forward-looking statements due to a number of factors, without limitation, including the future impact of the COVID-19 pandemic on the Company’s operations and results, including effects on the financial health of customers (including collections); logistical challenges and supply chain disruptions, geopolitical conditions, or other events; an inability to realize the anticipated benefits from our operational initiatives, including our large capital investments in Chattanooga and Kimball, Tennessee, and Decatur, Illinois, plant closures, and our reorganization and related strategic realignment activities; an inability to attract or retain a skilled and diverse workforce, increased competition related to the workforce and labor markets; an inability to protect the Company’s information systems against service interruption, misappropriation of data or breaches of security; failure to comply with personal data protection and privacy laws; cyclical and changing demand in core markets such as municipal spending, residential construction, and natural gas distribution; government monetary or fiscal policies; the impact of adverse weather conditions; the impact of manufacturing and product performance; the impact of wage, commodity and materials price inflation; the impact of warranty claims; an inability to successfully resolve significant legal proceedings or government investigations; compliance with environmental, trade and anti-corruption laws and regulations; climate change and legal or regulatory responses thereto; changing regulatory, trade and tariff conditions; the failure to integrate and/or realize any of the anticipated benefits of recent acquisitions or divestitures; an inability to achieve some or all of our Environmental, Social, and Governance goals; and other factors that are described in the section entitled “RISK FACTORS” in Item 1A of the Company’s most recent Annual Report on Form 10-K and later filings on Form 10-Q, as applicable. Forward-looking statements do not guarantee future performance and are only as of the date they are made. The Company undertakes no duty to update its forward-looking statements except as required by law. Undue reliance should not be placed on any forward-looking statements. You are advised to review any further disclosures the Company makes on related subjects in subsequent Forms 10-K, 10-Q, 8-K and other reports filed with the U.S. Securities and Exchange Commission.

10 Mueller is Uniquely Positioned to Address Opportunities with Utilities with its Leading Infrastructure Products and Installed Base

11 Water Utilities Are Facing Many Challenges • Unrealistic for U.S. water utilities and local governments to bridge the gap between their current capital spending and projected need for capital spending, based on the age and life expectancy of their infrastructure • Moving forward the industry will have to use multiple approaches to extend the life of their assets including measured allocation of capital funds, product innovation, predictive maintenance planning, and rate increases • Climate change is reducing both water availability and quality; solutions to retain, treat, and recycle water will need to be incorporated into investment and operating plans • Codification of contaminants regulation could accelerate innovation around testing for and removal of pollutants Aging Infrastructure Digitization Budget Pressures Aging Workforce Urbanization Population Shifts Water Utilities Implications for Utilities • Municipal repair and replacement remains a tailwind • More detailed customer segmentation is needed to market targeted points of differentiation to disparate users • Connecting infrastructure network to provide both predictive insight and mechanical functionality will enhance value proposition, thereby increasing adoption of products and services • Participating in training of the next generation of utility workers could be a competitive advantage • Web-enabled tools are needed to engage new generation of users • Alternative business models likely to become more attractive to utilities Implications for Mueller Regulation Climate
