Item 9A. CONTROLS AND PROCEDURES Evaluation of Disclosure Controls and Procedures We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and that such information is accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure. Our Chief Executive Officer and Chief Financial Officer evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this Annual Report. Based on this evaluation, those officers have concluded that, at September 30, 2021, our disclosure controls and procedures were effective. Changes in Internal Control over Financial Reporting During the quarter ended September 30, 2021, we continued our multi-year implementation of upgrades to our enterprise resource planning (“ERP”) system. Aside from the above, there were no changes in internal control over financial reporting during the quarter ended September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Management’s Report on Internal Control over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act). Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We assessed the effectiveness of our internal control over financial reporting at September 30, 2021. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013 framework). After doing so, management concluded that, at September 30, 2021, our internal control over financial reporting was effective. The effectiveness of our internal control over financial reporting at September 30, 2021 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included in this Annual Report.

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Mueller Water Products, Inc. and subsidiaries (the Company) as of September 30, 2021 and 2020, the related consolidated statements of operations, comprehensive income , equity and cash flows for each of the three years in the period ended September 30, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at September 30, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended September 30, 2021, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of September 30, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated November 18, 2021 expressed an unqualified opinion thereon. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit s . We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. F- 1 Table of Contents Index to Financial Statements Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates. Valuation of Goodwill - Krausz Industries Reporting Unit Description of the Matter As described in Note 6 to the consolidated financial statements, goodwill is tested at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. As of September 1, 2021, the Company performed a quantitative assessment of the $91.2 million in goodwill of the Krausz Industries (“Krausz”) reporting unit. The Company determined the fair value of the Krausz reporting unit using valuation techniques including the discounted cash flow method, a form of the income approach, and the guideline public company method, a form of the market approach. Auditing management’s impairment test over the Krausz reporting unit goodwill using the discounted cash flow method involved especially subjective judgments due to the significant estimation uncertainty in determining the fair value of the reporting unit. In particular, the fair value estimate was sensitive to significant assumptions such as forecasted revenues, EBITDA margins and the discount rate. These significant assumptions are forward-looking and could be affected by future industry, market and economic conditions. How We Addressed the Matter in Our Audit We tested the Company’s controls over review of the fair value of the Krausz reporting unit. This included testing controls over management’s review of the valuation model and the significant assumptions described above. To test the estimated fair value of the Krausz reporting unit, we performed audit procedures that included, among others, assessing the methodologies used to estimate fair value, testing the significant assumptions used to develop the fair value estimate, and testing the underlying data used by the Company in its analysis for completeness and accuracy. For example, we evaluated the reasonableness of management’s forecasted revenues and EBITDA margins used in the fair value estimates by comparing those assumptions to the historical results of Krausz and current industry, market and economic forecasts. We also involved our valuation specialists to evaluate the valuation methodologies and the reasonableness of the discount rate. As part of this evaluation, we compared the discount rate to market data. In addition, we performed a sensitivity analysis on the significant assumptions to evaluate the potential change in the fair value of the reporting unit that would result from the changes in assumptions. /s/ Ernst & Young LLP We have served as the Company’s auditor since 2007. Atlanta, Georgia November 18, 2021 F- 2 Table of Contents Index to Financial Statements Report of Independent Registered Public Accounting Firm To the Stockholders and Board of Directors of Mueller Water Products, Inc. Opinion on Internal Control over Financial Reporting We have audited Mueller Water Products, Inc. and subsidiaries’ internal control over financial reporting as of September 30, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Mueller Water Products, Inc. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of September 30, 2021, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of September 30, 2021 and 2020, the related consolidated statements of operations, comprehensive income, equity and cash flows for each of the three years in the period ended September 30, 2021, and the related notes and our report dated November 18, 2021 expressed an unqualified opinion thereon. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young LLP Atlanta, Georgia November 18, 2021 F- 3 Table of Contents Index to Financial Statements MUELLER WATER PRODUCTS, INC.

F- 9 Table of Contents Index to Financial Statements MUELLER WATER PRODUCTS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1. Organization Mueller Water Products, Inc., a Delaware corporation, together with its consolidated subsidiaries, operates in two business segments: Infrastructure and Technologies. Infrastructure manufactures valves for water and gas systems, including butterfly, iron gate, tapping, check, knife, plug, automatic control and ball valves, as well as dry-barrel and wet-barrel fire hydrants and pipe repair products. Technologies offers metering systems, leak detection, pipe condition assessment and other products and services for the water infrastructure industry. The “Company,” “we,” “us” or “our” refer to Mueller Water Products, Inc. and its subsidiaries. With regard to the Company’s segments, “we,” “us” or “our” may also refer to the segment being discussed. We sold our Anvil segment on January 6, 2017 and our U.S. Pipe segment on April 1, 2012. We have approximately 3,400 employees globally, of which 66% of our hourly workers are covered by collective bargaining agreements. In July 2014, Infrastructure acquired a 49 % ownership in an industrial valve joint-venture for $ 1.7 million. As a result of substantive control features in the joint-venture agreement, all of the joint venture’s assets, liabilities and results of operations were included in our consolidated financial statements. The noncontrolling interest portion was included in selling, general and administrative expenses. Noncontrolling interest was recorded at its carrying value, which approximated fair value. Infrastructure acquired the remaining 51% noncontrolling interest on October 3, 2019. On December 3, 2018, we completed our acquisition of Krausz Industries Development Ltd. and subsidiaries (“Krausz”). During our 2020 and 2019 fiscal years, we included the financial statements of Krausz on a one-month lag. Refer to Note 5. for additional disclosures. During the three months ended March 31, 2021, we aligned the consolidation of the financial statements of Krausz in the Company’s consolidated financial statements, eliminating the previous inclusion of Krausz financial statements with a one-month reporting lag. In accordance with applicable accounting literature, the elimination of the one-month reporting lag is considered to be a change in accounting principle. We believe this change in accounting principle is preferable as the financial statements of all of our subsidiaries are now reported on the same basis, providing the most current information available. The effect of the elimination of the reporting lag during the year ended September 30, 2021 resulted in an increase of $6.0 million to net sales and an increase of $1.4 million to operating income. We concluded that the effect of this change is not material to the balance sheets, statements of operations, statements of cash flows, net income and earnings per share and therefore have not retrospectively applied this change. On June 14, 2021, we acquired all the outstanding capital stock of i2O Water Ltd (“i2O”) a provider of pressure management solutions to more than 100 water companies in 45 countries. The consolidated balance sheet at September 30, 2021 includes the preliminary estimated fair values of the net assets of i2O. The Company is still reviewing the impact of taxes and certain other items. The results of i2O’s operations and cash flows for the period subsequent to the acquisition are included in the consolidated statement of operations and consolidated statement of cash flows, respectively. Refer to Note 5. for additional disclosures related to the acquisition. Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), which require us to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, sales and expenses and the disclosure of contingent assets and liabilities for the reporting periods. Actual results could differ from those estimates. All significant intercompany balances and transactions have been eliminated. Certain reclassifications have been made to previously reported amounts to conform to the current presentation. Unless the context indicates otherwise, whenever we refer to a particular year, we mean our fiscal year ended or ending September 30 in that particular calendar year. New Markets Tax Credit Program On December 22, 2020, we entered into a financing transaction with Wells Fargo Community Investment Holdings, LLC (“Wells Fargo”) related to our brass foundry construction project in Decatur, Illinois under a qualified New Markets Tax Credit program (“NMTC”). The NMTC is a federal program intended to encourage capital investment in qualified lower income communities. Under the NMTC, investors claim federal income tax credits over a period of seven years in connection with qualified investments in the equity of community development entities (“CDE”s), which are privately managed investment institutions that are certified to make qualified low-income community investments, such as in our foundry project. Under the NMTC, Wells Fargo contributed capital of $ 4.8 million to an investment fund and we loaned $ 12.2 million to the fund. Wells Fargo is entitled to the associated tax credits, which are subject to 100% recapture if we do not comply with various regulations and contractual provisions surrounding the foundry project. We have indemnified Wells Fargo for any loss F- 10 Table of Contents Index to Financial Statements or recapture of tax credits related to the transaction until the seven-year period elapses. We do not anticipate any credit recaptures will be required in connection with this arrangement. The investment fund contributed $ 16.5 million cash for a 99.99% stake in a joint venture (“Sub-CDE”) with a CDE. The Sub-CDE then loaned $ 16.2 million to us, with the use of the loan proceeds restricted to foundry project expenditures. This transaction also includes a put/call provision under which we may be obligated or entitled to repurchase Wells Fargo’s interest in the investment fund. We believe that Wells Fargo will exercise its put option in December 2027 for nominal consideration, resulting in our becoming the sole owner of the investment fund, cancelling the related loans, and recognizing an estimated gain of $ 3.9 million. We determined that the investment fund and the Sub-CDE are variable interest entities (“VIEs”) and that we are the primary beneficiary of the VIEs. The ongoing activities of the VIEs, namely collecting and remitting interest and fees and administering NMTC compliance, were contemplated in the initial design of the transaction and are not expected to significantly affect economic performance throughout the life of the VIEs. Additionally, we are obligated to deliver tax benefits and provide various other guarantees to Wells Fargo and to absorb the losses of the VIEs. Wells Fargo does not have a material interest in the underling economics of the project. Consequently, we have included the financial statements of the VIEs in our consolidated financial statements. Intercompany transactions between us and the VIEs have been eliminated in consolidation. Wells Fargo’s contribution to the investment fund is consolidated in our financial statements as an Other noncurrent liability as a result of its redemption features. Direct costs associated with Wells Fargo’s capital contribution have been netted against the recorded proceeds, resulting in a net cash contribution of $ 3.9 million. Other direct costs associated with the transaction were capitalized and will be recognized as interest expense over the seven-year tax credit period. Incremental costs to maintain the structure during the compliance period are expensed as incurred. Note 2. Summary of Significant Accounting Policies Cash and Cash Equivalents. All highly liquid investments with remaining maturities of 90 days or less when purchased are classified as cash equivalents. Where there is no right of offset against cash balances, outstanding checks are included in accounts payable. Receivables, net. Receivables are amounts due from customers. To reduce credit risk, credit investigations are generally performed prior to accepting orders from new customers and, when necessary, letters of credit, bonds or other instruments are required to ensure payment. We present trade receivables net of customer discounts and an allowance for credit losses. Our consolidated statements of operations reflect the measurement of credit losses for newly recognized trade receivables, as well as the expected increases or decreases of expected credit losses that have taken place during the period. When we determine a specific trade receivable will not be collected, we charge off the uncollectible amount against the allowance. Our periodic evaluations of expected credit losses are based upon our judgments regarding prior collection experience, specific customer creditworthiness, other current conditions, and forecasts of current economic trends within the industries served that may affect the collectability of the reported amounts. Significantly weaker than anticipated industry or economic conditions could impact our customers’ ability to pay such that actual credit losses may be greater than the amounts provided for in this allowance. The following table summarizes information concerning our allowance for credit losses. 2021 2020 2019 (in millions) Balance at beginning of year $ 2.5 $ 1.5 $ 1.4 Provision charged to expense 1.1 1.1 0.3 Other ( 0.1 ) ( 0.1 ) ( 0.2 ) Balance at end of year $ 3.5 $ 2.5 $ 1.5 Inventories, net. Inventories are recorded at the lower of first-in, first-out method cost or estimated net realizable value. We evaluate our inventory in terms of excess and obsolete exposures. This evaluation includes such factors as anticipated usage, inventory turnover, inventory levels and ultimate product sales value. Inventory cost includes an overhead component F- 11 Table of Contents Index to Financial Statements that is affected by levels of production and actual costs incurred. We periodically evaluate the effects of production levels and costs capitalized as part of inventory. The following table summarizes information concerning our inventory valuation reserves. 2021 2020 2019 (in millions) Balance at beginning of year $ 11.7 $ 7.5 $ 5.1 Provision charged to expense 5.9 4.7 3.4 Inventory disposed ( 3.6 ) ( 0.7 ) ( 1.2 ) Other 0.8 0.2 0.2 Balance at end of year $ 14.8 $ 11.7 $ 7.5 Maintenance and repair supplies and tooling. Maintenance and repair supplies and tooling is included in Other current assets and Other noncurrent assets. Costs for perishable tools and maintenance items are expensed when put into service. Costs for more durable items are amortized over their estimated useful lives, ranging from 3 to 10 years. Property, Plant and Equipment, net. Property, plant and equipment is recorded at cost, less accumulated depreciation. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets. Estimated useful lives are 10 to 20 years for land improvements, 10 to 40 years for buildings and 3 to 15 years for machinery and equipment. Leasehold improvements and capitalized leases are depreciated using the straight-line method over the lesser of the useful life of the asset or the remaining lease term. Gains and losses upon disposition are reflected in operating results in the period of disposition. Direct internal and external costs to implement computer systems and internal-use software are capitalized. Capitalized costs are depreciated over the estimated useful life of the system or software, generally six years, beginning when software is ready for its intended use. Liabilities are recognized at fair value for asset retirement obligations related to plant and landfill closures in the period in which they are reasonably estimable and the carrying amounts of the related long-lived assets are correspondingly adjusted. Over time, the liabilities are accreted to their estimated future values. At September 30, 2021 and 2020, asset retirement obligations were $ 3.8 million. Leases. Refer to Note 4. for information regarding our leases. Accounting for the Impairment of Long-Lived Assets. We test indefinite-lived intangible assets and goodwill for impairment annually or more frequently if events or circumstances indicate impairment is possible. We perform our annual impairment testing at September 1. We amortize finite-lived intangible assets over their respective estimated useful lives and review for impairment if events or circumstances indicate impairment is possible. Refer to Note 6. for information regarding our impairment testing. Workers’ Compensation. Our exposure to workers’ compensation claims is generally limited to $ 0.8 million per incident. Liabilities, including those related to claims incurred but not reported, are recorded principally using annual valuations based on discounted future expected payments and using historical data combined with insurance industry data when historical data is limited. Our gross workers’ compensation liabilities were $ 10.5 million as of September 30, 2021, and we expect to recover $ 3.5 million in insurance which is included as a receivable in Other current assets and Other noncurrent assets as of September 30, 2021. As of September 30, 2020, our net worker’s compensation liability was $ 6.2 million. Warranty Costs. We accrue for warranty expenses, which include costs of repair and/or replacement, including labor, materials, equipment, freight and reasonable overhead costs. We accrue for the estimated cost of product warranties at the time of sale if such costs are determined to be probable and reasonably estimable at that time. We monitor and analyze our warranty experience and costs periodically and may revise our warranty accruals as necessary. Critical factors in our accrual analyses include warranty terms, specific claim situations, general incurred and projected failure rates, the nature of product failures, product and labor costs, and general business conditions. Activity in our accrued warranty, reported as part of both other current liabilities and other noncurrent liabilities, is presented below. F- 12 Table of Contents Index to Financial Statements 2021 2020 2019 (in millions) Balance at beginning of year $ 14.4 $ 17.1 $ 20.0 Warranty accruals 3.5 2.6 3.9 Warranty costs ( 8.2 ) ( 5.3 ) ( 6.8 ) Balance at end of year $ 9.7 $ 14.4 $ 17.1 Deferred Financing Costs. Costs to finance debt are charged to expense over the lives of the debt agreements. Remaining costs and the future period over which financing costs would be charged to expense are reassessed when amendments to the related financing agreements or prepayments occur. Deferred financing costs are offset against the underlying long-term debt in the accompanying consolidated balance sheets. Deferred financing costs under agreements that do not have outstanding debt and in other instances, such as our ABL Agreement and with regard to our NMTC transaction, are included in Other noncurrent assets consistent with the life of the instrument. Deferred financing costs of $ 6.6 million at September 30, 2021 are scheduled to amortize as follows: $ 1.0 million related to the ABL Agreement and $0.3 million related to the NMTC transaction which are amortized on a straight-line basis and; $ 5.3 million related to the 4.0% Senior Unsecured Notes (“4.0% Senior Notes”) which is amortized using the effective interest rate method. All such amortization will be over the remaining term of the respective debt. Refer to Note 8. for disclosures related to our borrowing arrangements. Derivative Instruments and Hedging Activities. We manage U.S. dollar - Canadian dollar exchange rate risk related to an intercompany loan with swap contracts, which we have not designated as hedges. As a result, the changes in the fair value of these contracts are reported currently in earnings. The values of our currency swap contracts were liabilities of $ 1.1 million and $ 0.2 million as of September 30, 2021 and 2020, respectively, and are included in Other current liabilities and Other noncurrent liabilities, respectively, in our consolidated balance sheets. The currency swap contracts expire in February 2022. Income Taxes. Deferred tax liabilities and deferred tax assets are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns. Such liabilities and assets are determined based on the differences between the financial statement basis and the tax basis of assets and liabilities, using tax rates in effect for the years in which the differences are expected to reverse. A valuation allowance is provided when, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. We only record tax benefits for positions that management believes are more likely than not of being sustained under audit based solely on the technical merits of the associated tax position. The amount of tax benefit recognized for any position that meets the more-likely-than-not threshold is the largest amount of the tax benefit that we believe is greater than 50 % likely of being realized. Environmental Expenditures. We capitalize environmental expenditures that increase the life or efficiency of noncurrent assets or that reduce or prevent environmental contamination. We accrue for environmental expenses resulting from existing conditions that relate to past operations when the costs are probable and reasonably estimable. We are indemnified under an agreement with a predecessor to Tyco for certain environmental liabilities that existed at August 16, 1999. Refer to Note 17. for additional disclosures regarding our environmental liabilities. Revenue Recognition. Refer to Note 3. for disclosures regarding our revenues. Stock-based Compensation. Compensation expense for stock-based awards granted to employees and directors is based on the fair value at the grant dates for our stock-settled share awards and is based on the fair value at each reporting date for our cash-settled share awards. Refer to Note 12. for more information regarding our stock-based compensation. Stock-based compensation expense is included within Selling, general and administrative expenses. Research and Development. Research and development costs are expensed as incurred. Advertising. Advertising costs are expensed as incurred. Translation of Foreign Currency. Assets and liabilities of our businesses whose functional currencies are not denominated in the United States dollar are translated into United States dollars using currency exchange rates at the balance sheet date. Revenues and expenses are translated at average currency exchange rates during the period. Foreign currency translation gains F- 13 Table of Contents Index to Financial Statements and losses are reported as a component of accumulated other comprehensive income (loss). Gains and losses resulting from foreign currency transactions are included in earnings as incurred. Recently Adopted Accounting Pronouncements During 2016, the Financial Accounting Standards Board (“FASB”) issued standard Accounting Standard Codification (“ASC”) 326 - Current Expected Credit Losses (“ASC 326”) to replace the “incurred loss” impairment approach with an “expected loss” approach. This requires consideration of a broader range of reasonable and supportable information to estimate credit losses. We have completed historical and forward-looking analyses for receivables and adopted this guidance effective October 1, 2020. Upon adoption, there was an immaterial impact of $0.1 million to our retained earnings. Accounting Pronouncements Not Yet Adopted In December 2019, the FASB issued Accounting Standards Update (“ASU”) No. 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by clarifying and amending existing guidance related to the recognition of franchise tax, the evaluation of a step up in the tax basis of goodwill, and the effects of enacted changes in tax laws or rates in the effective tax rate computation, among other clarifications. ASU 2019-12 is effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year, with early adoption permitted. We will adopt this standard on October 1, 2021 and it is not expected to have a material impact on our financial statements. In March 2020, the FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" (“ASU 2020-04”). The new guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference the London Inter Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to reference rate reform. ASU 2020-04 is effective from March 12, 2020, but can be adopted prospectively from a date within an interim period subsequent to March 12, 2020. We are currently evaluating our contracts and the optional expedients provided by ASU 2020-04. We will adopt this standard on October 1, 2021 and it is not expected to have a material impact on our financial statements. Note 3. Revenue from Contracts with Customers We recognize revenue when control of promised products or services is transferred to our customers, in amounts that reflect the consideration to which we expect to be entitled in exchange for those products or services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, the payment terms are identified, the contract has commercial substance and collectability of consideration is probable. We determine the appropriate revenue recognition for our contracts with customers by analyzing the type, terms and conditions of each contract or arrangement with a customer. Disaggregation of Revenue Refer to Note 16. for disaggregation our revenues from contracts with customers by reportable segment and by geographical region, which we believe best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Geographical region represents the location of the customer. Contract Asset and Liability Balances Differences in the timing of revenue recognition, billing and cash collection result in customer receivables, advance payments and billings in excess of revenue recognized. Customer receivables include amounts billed and currently due from customers as well as unbilled amounts (contract assets). Amounts are billed in accordance with contractual terms and unbilled amounts arise when the timing of billing differs from the timing of revenue recognized. Advance payments and billings in excess of revenue are recognized and recorded as deferred revenue, the majority of which is classified as current based on the timing when we expect to recognize revenue. We include current deferred revenue within Other current liabilities in the accompanying consolidated balance sheets. Deferred revenues represent contract liabilities and are recorded when customers remit cash payments in advance of our satisfaction of performance obligations under contractual arrangements. Contract liabilities are reversed when the performance obligation is satisfied and revenue is recognized. F- 14 Table of Contents Index to Financial Statements The table below represents the balances of our customer receivables and deferred revenues. September 30, 2021 2020 (in millions) Billed receivables $ 217.0 $ 180.3 Unbilled receivables 2.3 5.3 Total customer receivables, gross $ 219.3 $ 185.6 Deferred revenues $ 5.4 $ 5.6 Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. Our performance obligations are satisfied at a point in time as related to sales of equipment or over time as related to our software hosting and leak detection monitoring services. Performance obligations are supported by customer contracts, which provide frameworks for the nature of the distinct products or services. We allocate the transaction price of each contract to the performance obligations on the basis of standalone selling price and recognize revenue when control of the performance obligation transfers to the customer. The transaction price is adjusted for our estimate of variable consideration which may include discounts, and rebates. To estimate variable consideration, we apply the expected value or the most likely amount method, based on whichever method most appropriately predicts the amount of consideration we expect to receive. The method applied is typically based on historical experience and known trends. We constrain the amounts of variable consideration that are included in the transaction price, to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur or when uncertainties around the variable consideration are resolved. We exclude from the measurement of the transaction price all taxes assessed by a governmental authority. We classify shipping and handling costs, such as freight to our customers’ destinations, as a component of cost of goods sold. We have elected to use the practical expedient to not adjust the transaction price of a contract for the effects of a significant financing component if, at the inception of the contract, we expect that the period between when we transfer a product or service to a customer and when a customer remits payment will be one year or less. Revenues from products and services transferred to customers at a point in time represented 98 % , 99 % and 98 % of our revenues in the years ended September 30, 2021, 2020 and 2019, respectively. The revenues recognized at a point in time related to the sale of our products are recognized when the obligations of the terms of our contract are satisfied, which generally occurs upon shipment when control of the product transfers to the customer. Revenues from products and services transferred to customers over time represented 2 %, 1 % and 2 % of our revenues in the years ended September 30, 2021, 2020 and 2019, respectively. We offer warranties to our customers in the form of assurance-type warranties, which provide assurance that the products provided will function as intended and comply with any agreed-upon specifications. These cannot be purchased separately. Costs to Obtain or Fulfill a Contract We incur certain incremental costs to obtain a contract, which primarily relate to incremental sales commissions. Our commissions are paid based on a combination of orders and shipments, and we reserve the right to claw back any commissions in case of product returns or lost collections. As the expected benefit associated with these incremental costs is generally one year or less based on the nature of the product sold and benefits received, we have applied a practical expedient and therefore do not capitalize the related costs and expense them as incurred. F- 15 Table of Contents Index to Financial Statements Note 4. Leases On October 1, 2019, we adopted ASC 842 - Leases utilizing the modified retrospective approach. Adoption of the new standard resulted in an increase to total assets and liabilities as a result of recording lease right-of-use assets (“ROU”) and lease liabilities related to our operating lease portfolio. We elected three practical expedients for transition, which include the carry forward of our leases without reassessing whether any contracts are leases or contain leases, lease classification and initial direct costs as well as applying hindsight when determining the lease term and when assessing impairment of ROU assets at the adoption date. This allows us to update our assessments according to new information and changes in facts and circumstances that have occurred since lease inception. Presentation of Leases We lease certain office, warehouse, manufacturing, distribution, and research and development facilities and equipment under operating leases. Our leases have remaining lease terms of up to 12 years. The terms and conditions of our leases may include options to extend or terminate the lease which are considered and included in the lease term when these options are reasonably certain of exercise. We determine if a contract is, or contains, a lease at inception by evaluating whether the contract conveys the right to control the use of an identified asset. For all classes of leased assets, we have elected the practical expedient to account for any non-lease components in the contract together with the related lease component in the same unit of account. ROU assets and lease liabilities are recognized in our consolidated balance sheets at the commencement date based on the present value of remaining lease payments over the lease term. Additionally, ROU assets include any lease payments made at or before the commencement date, as well as any initial direct costs incurred, and are reduced by any lease incentives received. As most of our operating leases do not provide an implicit rate, we apply our incremental borrowing rate to determine the present value of remaining lease payments. Our incremental borrowing rate is determined based on information available at the commencement date of the lease. For all classes of leased assets, we have applied an accounting policy election to exclude short-term leases from recognition in our consolidated balance sheets. A short-term lease has a lease term of 12 months or less at the commencement date and does not include a purchase option that is reasonably certain of exercise. We recognize short-term lease expense in our condensed consolidated statements of operations on a straight-line basis over the lease term. Our short-term lease expense for the years ended September 30, 2021 and 2020 and short-term lease commitments at September 30, 2021 are immaterial. We have certain lease contracts with terms and conditions that provide for variability in the payment amount based on changes in facts or circumstances occurring after the commencement date. These variable lease payments are recognized in our consolidated statements of operations as the obligation is incurred. F- 16 Table of Contents Index to Financial Statements At September 30, 2021, any legally-binding minimum lease payments for operating leases signed but not yet commenced, subleases, leases that imposed significant restrictions or covenants, related party leases or sale-leaseback arrangements were immaterial.

Acquisitions Acquisition of Krausz On December 3, 2018, we completed our acquisition of the outstanding equity of Krausz, a manufacturer of pipe couplings, grips and clamps with operations in the United States and Israel, for $ 140.7 million, net of cash acquired, including the assumption and simultaneous repayment of certain debt of $ 13.2 million. The acquisition of Krausz was financed with cash on hand. We believe that the Krausz product line is complementary to our existing Infrastructure products and will improve our positioning in the pipe repair market. We have recognized the assets acquired and liabilities assumed at their estimated acquisition date fair values, with the excess of the purchase price over the estimated fair values of the identifiable net assets acquired recorded as goodwill. During 2020, we reduced property, plant and equipment by $ 0.3 million, which resulted in an increase to goodwill of $ 0.3 million. The accounting for the business combination is considered final. The results of Krausz, including net sales of $ 37.2 million for 2019, are included within our Infrastructure segment for all periods following the acquisition date. The goodwill below is attributable to the strategic opportunities and synergies that we expect to arise from the acquisition of Krausz and the value of its workforce and is nondeductible for income tax purposes. Identified intangible assets consist of patents, customer relationships and favorable leasehold interests with an estimated weighted-average useful life of approximately 12 years and trade names with an indefinite life. Values of intangible assets were determined using a discounted cash flow method. F- 18 Table of Contents Index to Financial Statements The following is a summary of the estimated fair values of the net assets acquired (in millions): Assets, net of cash: Receivables $ 6.9 Inventories 17.0 Other current assets 0.2 Property, plant and equipment 8.1 Other non-current assets 1.7 Identified intangible assets: Patents 32.1 Customer relationships 8.7 Trade names 4.6 Favorable leasehold interests 2.3 Goodwill 80.4 Liabilities: Accounts payable ( 5.5 ) Other current liabilities ( 2.9 ) Deferred income taxes ( 11.2 ) Other non-current liabilities ( 1.7 ) Consideration paid 140.7 Repayment of Krausz debt ( 13.2 ) Consideration paid included in net cash used in investing activities $ 127.5 Acquisition of i2O Water Ltd On June 14, 2021, we acquired all of the outstanding capital stock of i2O Water Ltd for $19.7 million, net of cash acquired. The purchase agreement provides for customary final adjustments, including a net working capital adjustment, which we expect to occur during the calendar year 2021. We have recognized the assets acquired and liabilities assumed at their estimated acquisition date fair values, with the excess of the purchase price over the estimated fair values of the identifiable net assets acquired recorded as goodwill. The accounting for the business combination is considered to be preliminary. We are still reviewing the impact of taxes and other certain items. The results of i2O are included within our Technologies segment. The goodwill below is attributable to the strategic opportunities and synergies that we expect to arise from the acquisition of i2O and the value of its workforce. The goodwill is nondeductible for income tax purposes. Identified intangible assets consist of customer relationships, non-compete agreements and developed technology with an estimated weighted-average useful life of approximately 12 years and trade names with an indefinite life. Values of intangible assets were determined using a discounted cash flow method. F- 19 Table of Contents Index to Financial Statements The following is a summary of the preliminary estimated fair values of the net assets acquired (in millions): Assets, net of cash: Receivables $ 0.5 Inventories 0.6 Other current assets 0.9 Identified intangible assets: Tradename 1.8 Customer relationships 2.1 Non-compete agreements 0.1 Developed technology 3.5 Goodwill 12.1 Liabilities: Accounts payable ( 0.8 ) Other current liabilities ( 1.1 ) Fair value of net assets acquired, net of cash $ 19.7 Note 6. Intangible Assets and Goodwill Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis each September 1 st and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. We completed our annual impairment tests of intangible assets and goodwill as of September 1, 2021, and determined th ere were no impairments. Our goodwill primarily relates to the Krausz reporting unit which was $ 91.2 million as of September 1, 2021. Intangible Assets Direct internal and external costs to develop software licensed by Technologies’ customers are capitalized and amortized over the 6 -year estimated useful life of the software, beginning when the software is ready for its intended use. At September 30, 2021, the remaining weighted-average amortization period for this software was 1.8 years. Amortization expense related to such software assets was $ 3.3 million in each of our 2021, 2020 and 2019 fiscal years. Amortization expense for each of the next five years is scheduled to be $ 3.5 million in 2022, $ 2.7 million in 2023, $ 2.1 million in 2024, $ 1.1 million in 2025 and $ 0.5 million in 2026. At September 30, 2021, the remaining weighted-average amortization period for business combination-related finite-lived customer relationships and technology intangible assets were 4.4 years and 4.5 years, respectively. Amortization expense related to these assets was $ 25.2 million, $ 24.9 million and $ 23.7 million for 2021, 2020 and 2019, respectively. Amortization expense for each of the next five years is scheduled to be $ 25.4 million in 2022, $ 24.8 million in 2023, $ 24.8 million in 2024, $ 5.2 million in 2025 and $ 4.4 million in 2026.

Income Taxes The components of income before income taxes are presented below. 2021 2020 2019 (in millions) U.S. $ 94.0 $ 89.7 $ 78.4 Non-U.S. 0.9 4.4 3.7 Income before income taxes $ 94.9 $ 94.1 $ 82.1 F- 21 Table of Contents Index to Financial Statements The Tax Cuts and Jobs Act (the “Act”) imposed a one-time transition tax on the undistributed, previously untaxed, post-1986 foreign “earnings and profits” (as defined by the IRS) of certain United States-owned corporations. At September 30, 2021, the remaining balance of our transition obligation is $ 4.7 million, which will be paid annually through January 2026, as provided in the Act. Other than for Krausz’s investment in its United States subsidiary, we have not recorded income taxes for unrepatriated foreign earnings that may be subject to withholding tax or any outside cost basis differences inherent in our foreign subsidiaries, as these amounts continue to be indefinitely reinvested in foreign operations. We have a foreign tax credit carryforward of $ 4.5 million, for which we have recorded a valuation allowance as we do not expect to utilize it prior to expiration. The federal income tax returns for Mueller Co. are closed for years prior to 2005 and for Mueller Water Products, Inc. for 2007 and 2008. Our 2009 through 2016 returns are closed except to the extent net operating losses from those years have been utilized on subsequent years’ returns. We also remain liable for any taxes related to U.S. Pipe income for periods prior to 2012 pursuant to the terms of the sale agreement with the purchaser of the segment. Our state income tax returns are generally closed for years prior to 2017, except to the extent of our state net operating loss carryforwards. Our Canadian income tax returns are generally closed for years prior to 2014. We do not have any material unpaid assessments.

We recognize interest related to uncertain tax positions as interest expense and recognize any penalties incurred as a component of selling, general and administrative expenses. At September 30, 2021 and 2020, we had $ 0.6 million and $ 0.4 million, respectively, of accrued interest expense related to unrecognized tax benefits.

Our state net operating loss carryforwards, which expire between the years 2024 and 2032, remain available to offset future taxable earnings. Note 8. Borrowing Arrangements The components of our long-term debt are as follows: September 30, 2021 2020 (in millions) 4.0% Senior Notes $ 450.0 $ — 5.5% Senior Notes — 450.0 ABL Agreement — — Other 2.2 2.5 452.2 452.5 Less deferred financing costs ( 5.3 ) ( 4.9 ) Less current portion of long-term debt ( 1.0 ) ( 1.1 ) Long-term debt $ 445.9 $ 446.5 The scheduled maturities of all borrowings outstanding at September 30, 2021 for each of the following years are $ 1.0 million in 2022, $ 0.7 million in 2023, $ 0.3 million in 2024, $ 0.1 million in 2025 and $ 0.1 million in 2026. F- 24 Table of Contents Index to Financial Statements ABL Agreement . Our ABL Agreement consists of a revolving credit facility for up to $ 175 million that includes up to $ 25 million through swing line loans and may have up to $ 60 million of letters of credit. The ABL Agreement permits us to increase the size of the credit facility by an additional $ 150 million in certain circumstances subject to adequate borrowing base availability. Borrowings under the amended ABL Agreement bear interest at a floating rate equal to LIBOR plus an applicable margin range of 200 to 225 basis points, or a base rate, as defined in the ABL Agreement, plus an applicable margin range of from 100 to 125 basis points. At September 30, 2021 the applicable margin was LIBOR plus 200 basis points. The ABL Agreement is subject to mandatory prepayments if total outstanding borrowings under the ABL Agreement are greater than the aggregate commitments under the revolving credit facility or if we dispose of overdue accounts receivable in certain circumstances. The borrowing base under the ABL Agreement is equal to the sum of (a) 85% of the value of eligible accounts receivable and (b) the lesser of (i) 70% of the value of eligible inventory or (ii) 85% of the net orderly liquidation value of the value of eligible inventory, less certain reserves. Prepayments can be made at any time without penalty. Substantially all of our United States subsidiaries are borrowers under the ABL Agreement and are jointly and severally liable for any outstanding borrowings. Our obligations under the ABL Agreement are secured by a first-priority perfected lien on all of our United States inventory, accounts receivable, certain cash and other supporting obligations. The ABL Agreement terminates on July 29, 2025 and includes a commitment fee for any unused borrowing capacity of 37.5 basis points per annum. Borrowings are not subject to any financial maintenance covenants unless excess availability is less than the greater of $ 17.5 million and 10 % of the Loan Cap as defined in the ABL Agreement. Excess availability based on September 30, 2021 data was $ 158.7 million, as reduced by $ 15.0 million of outstanding letters of credit and $ 1.3 million of accrued fees and expenses. 4.0% Senior Unsecured Notes. On May 28, 2021, we privately issued $ 450.0 million of 4.0% Senior Notes, which mature on June 15, 2029 and bear interest at 4.0 %, paid semi-annually in June and December. We capitalized $ 5.5 million of financing costs, which are being amortized over the term of the 4.0% Senior Notes using the effective interest method. Proceeds from the 4.0% Senior Notes, along with cash on hand were used to redeem our previously existing 5.5% Senior Notes. Substantially all of our United States subsidiaries guarantee the 4.0% Senior Notes, which are subordinate to borrowings under our ABL Agreement. Based on quoted market prices, which is a Level 1 measurement, the outstanding 4.0% Senior Notes had a fair value of $ 467.3 million as of September 30, 2021. An indenture securing the 4.0% Senior Notes (“Indenture”) contains customary covenants and events of default, including covenants that limit our ability to incur certain debt and liens. There are no financial maintenance covenants associated with the Indenture. We believe we were in compliance with these covenants at September 30, 2021. As set forth in the Indenture, we may redeem some or all of the 4.0% Senior Notes at any time or from time to time prior to June 15, 2024 at certain “make-whole” redemption prices and on or after June 15, 2024 at specified redemption prices. Additionally, we may redeem up to 40% of the aggregate principal amount of the 4.0% Senior Notes at any time or from time to time prior to June 15, 2024 with the net proceeds of specified equity offerings at specified redemption prices. Upon a change of control, we would be required to offer to purchase the 4.0% Senior Notes at a price equal to 101% of the outstanding principal amount of the 4.0% Senior Notes. 5.5% Senior Unsecured Notes. On June 12, 2018, we privately issued $ 450.0 million of 5.5% Senior Notes, which were set to mature in June 2026 and bore interest at 5.5 %, paid semi-annually. We called the 5.5% Senior Notes effective June 17, 2021 and redeemed the 5.5% Senior Notes with the proceeds from the 4.0% Senior Notes and cash on hand. As a result, we incurred $ 16.7 million in loss on extinguishment of debt, comprised of a $ 12.4 million call premium and a $ 4.3 million write-off of the remaining deferred debt issuance costs. . Note 9. Derivative Financial Instruments In connection with the acquisition of Singer Valve in 2017, we loaned funds to one of our Canadian subsidiaries. Although this intercompany loan has no direct effect on our consolidated financial statements, it creates exposure to currency risk for the Canadian subsidiary. To reduce this exposure, we entered into a United States dollar-Canadian dollar swap contract with the Canadian subsidiary and an offsetting Canadian dollar-United States dollar swap with a domestic bank. We have not designated these swaps as hedges and the changes in their fair value are included in earnings, where they offset the currency gains and losses associated with the intercompany loan. F- 25 Table of Contents Index to Financial Statements The values of our currency swap contracts were liabilities of $ 1.1 million and $ 0.2 million as of September 30, 2021 and 2020, respectively, and are included in Other current liabilities and Other noncurrent liabilities, respectively in our consolidated balance sheets. The currency swap contracts expire in February 2022. Note 10. Retirement Plans Defined Benefit Plans. We have had various pension plans (“Pension Plans”), which we funded in accordance with their requirements and, where applicable, in amounts sufficient to satisfy the minimum funding requirements of applicable laws. The Pension Plans provided benefits based on years of service and compensation or at stated amounts for each year of service. The annual measurement date for all Pension Plans was September 30. After September 30, 2019, our only remaining defined benefit plan was our United States Pension Plan (“Plan”). During 2019, we settled our obligations to our Canadian pension plan participants through a combination of lump-sum payments and purchases of annuities. We made a net contribution to the plans of $ 0.7 million, which was included in pension costs other than service, to fund these settlements. As a result, we no longer have any plan assets or obligation in connection with any Canadian defined benefit pension plan. During 2018, under terms of a negotiated labor contract, a group of our collectively bargained employees are no longer accruing benefits under a multi-employer pension plan. The affected employees are now participants in our defined contribution retirement plan with an employer match and one-time contribution of $ 0.4 million, which vested through 2020. During 2019, we recorded and paid an estimated settlement liability for exiting this plan, which resulted in an expense of $ 1.1 million, which we included in Strategic reorganization and other charges. As a result, we no longer have any plan assets or obligation in connection with any multi-employer pension plan. A summary of key assumptions for the valuations of our Pension Plans is as follows 2021 2020 2019 Weighted average used to determine benefit obligations: Discount rate 3.01 % 2.84 % 3.26 % Weighted average used to determine net periodic cost: Discount rate 2.84 % 3.26 % 4.37 % Expected return on plan assets 4.50 % 5.00 % 4.93 % The discount rates for determining the present value of pension obligations were selected using a “bond settlement” approach, which constructs a hypothetical bond portfolio that could be purchased such that the coupon payments and maturity values could be used to satisfy the projected benefit payments. The discount rate is the equivalent rate that results in the present value of the projected benefit payments equaling the market value of this bond portfolio. Only high quality (AA graded or higher), non-callable corporate bonds are included in this bond portfolio. We rely on the Pension Plans’ actuaries to assist in the development of the discount rate model. The expected returns on plan assets were determined with the assistance of the Pension Plans’ actuaries and investment consultants. Expected returns on plan assets were developed using forward looking returns over a time horizon of 10 to 15 years for major asset classes along with projected risk and historical correlations. F- 26 Table of Contents Index to Financial Statements Amounts recognized for Pension Plans are presented below. 2021 2020 (in millions) Projected benefit obligations: Beginning of year $ 359.5 $ 356.6 Service cost 1.5 1.5 Interest cost 9.9 11.2 Actuarial gain ( 10.8 ) 13.7 Benefits paid ( 23.3 ) ( 23.5 ) End of year $ 336.8 $ 359.5 Accumulated benefit obligations at end of year $ 336.8 $ 359.5 Plan assets: Beginning of year $ 360.4 $ 351.6 Actual return on plan assets 16.4 32.2 Employer contributions — 0.1 Benefits paid ( 23.3 ) ( 23.5 ) End of year $ 353.5 $ 360.4 Accrued benefit cost at end of year: Funded status $ 16.8 $ 0.9 Recognized on balance sheet: Other noncurrent assets $ 16.8 $ 0.9 Recognized in accumulated other comprehensive income (loss), before tax: Net actuarial loss 59.9 74.0 $ 59.9 $ 74.0 The components of net periodic benefit cost for our Pension Plans are presented below. 2021 2020 2019 (in millions) Service cost $ 1.5 $ 1.5 $ 1.6 Components of net periodic cost (benefit) excluded from operating income: Interest cost 9.9 11.2 13.9 Expected return on plan assets ( 15.7 ) ( 16.9 ) ( 16.2 ) Amortization of actuarial net loss 2.5 2.8 1.9 Pension settlement — — 0.7 Other — ( 0.1 ) 0.1 Pension (benefit) cost other than service ( 3.3 ) ( 3.0 ) 0.4 Net periodic benefit (benefit) cost $ ( 1.8 ) $ ( 1.5 ) $ 2.0 F- 27 Table of Contents Index to Financial Statements P lan activity in accumulated other comprehensive loss, before tax, in 2021 is presented below, in millions. Balance at beginning of year $ 74.0 Actuarial gain ( 11.6 ) Prior year actuarial loss amortization to net periodic cost ( 2.5 ) Balance at end of year $ 59.9 We amortize amounts in accumulated other comprehensive loss representing unrecognized prior year service cost and unrecognized loss related to the Pension Plans over the weighted average life expectancy of their inactive participants. Actuarial gains and losses are amortized using a corridor approach. The gain/loss corridor is equal to 10% of the greater of the benefit obligation and the market-related value of assets. Gains and losses in excess of the corridor are generally amortized over the average remaining lifetime of the plan participants. We expect to amortize $ 1.7 million of unrecognized loss into net periodic benefit cost from accumulated other comprehensive loss in 2022. S trategic asset allocations, tactical range at September 30, 2021 and actual asset allocations are as follows: Strategic asset allocation Actual asset allocations at September 30, Tactical range 2021 2020 2019 Fixed income investments 70 % 65 - 70 % 70 % 78 % 79 % Equity investments 30 25 - 30 % 29 21 19 Cash — 0 - 5 % 1 1 2 100 % 100 % 100 % 100 % Assets of the Plan are allocated to various investments to attain diversification and reasonable risk-adjusted returns while also managing the exposure to asset and liability volatility. These ranges are targets and deviations may occur from time to time as a result of market fluctuations. Portfolio assets are typically rebalanced to the allocation targets at least annually. The assets of the Plan are primarily invested in investment trusts valued at net asset value, which in turn hold fixed income and equity investments. The valuation methodologies used to measure the assets of the Plan at fair value are: • Fixed income fund investments held by the investment trusts are valued using the closing price reported in the active market in which the investment is traded or based on yields currently available on comparable securities of issuers with similar credit ratings; • Equity investments held by the investment trusts are valued using the closing price reported on the active market when reliable market quotations are readily available. When market quotations are not readily available, these assets are valued by a method the trustees believe accurately reflects fair value; and • Mutual funds are valued at the closing price reported on the active market. F- 28 Table of Contents Index to Financial Statements The assets of the Plan by level within the fair value hierarchy are as follows: September 30, 2021 Level 1 Level 2 Total (in millions) Fixed income $ 176.7 $ 70.3 $ 247.0 Equity: Large cap index funds 52.1 — 52.1 International stocks: International funds 52.5 — 52.5 Total equity 104.6 — 104.6 Cash and cash equivalents 1.9 — 1.9 $ 283.2 $ 70.3 $ 353.5 September 30, 2020 Level 1 Level 2 Total (in millions) Fixed income $ — $ 280.3 $ 280.3 Equity: Large cap index funds — 32.8 32.8 Mid cap index funds — 13.5 13.5 Small cap growth funds — 12.7 12.7 International stocks: Mutual funds 7.4 — 7.4 International funds — 10.4 10.4 Total equity 7.4 69.4 76.8 Cash and cash equivalents 3.3 — 3.3 $ 10.7 $ 349.7 $ 360.4 Our estimated future pension benefit payments are presented below (in millions). 2022 $ 24.1 2023 23.9 2024 23.5 2025 23.1 2026 22.7 2027-2031 $ 104.7 Defined Contribution Retirement Plans. Certain of our employees participate in defined contribution 401(k) plans or similar plans outside of the United States. We make matching contributions as a function of employee contributions which were $ 5.9 million, $ 5.3 million and $ 5.5 million during 2021, 2020 and 2019, respectively.

Stock-based Compensation Plans The effect of stock-based compensation on our consolidated statements of operations is presented below. 2021 2020 2019 (in millions, except per share data) Decrease in operating income $ 11.0 $ 7.2 $ 5.5 Decrease in net income 8.0 5.5 4.3 Decrease in earnings per basic share 0.05 0.03 0.03 Decrease in earnings per diluted share 0.05 0.03 0.03 We excluded 578,005 , 267,298 and 106,896 instruments from the calculation of diluted earnings per share for 2021, 2020 and 2019, respectively, because the effect of including them would have been antidilutive. At September 30, 2021, there was approximately $ 8.6 million of unrecognized compensation expense related to stock-based awards not yet vested. We expect to recognize this expense over a weighted average life of approximately 1.4 years. The Mueller Water Products, Inc. 2006 Stock Incentive Plan (“2006 Plan”) authorizes an aggregate of 20,500,000 shares of common stock that may be granted through the issuance of stock-based awards. Any awards canceled are available for reissuance. Generally, all of our employees and members of our Board of Directors are eligible to participate in the 2006 Plan. At September 30, 2021, 5,806,070 shares of common stock were available for future grants of awards under the 2006 Plan. This total assumes that the maximum number of shares will be earned for awards for which the final number of shares to be earned has not yet been determined. An award granted under the 2006 Plan vests at such times and in such installments as set by the Compensation and Human Resources Committee of our Board of Directors (“Compensation Committee”), but no award will be exercisable after the 10 -year anniversary of the date on which it is granted. Management expects some instruments will be forfeited prior to vesting. Grants to members of our Board of Directors are expected to vest fully. Based on historical forfeitures, we expect grants to others to be forfeited at an annual rate of 2 %. F- 30 Table of Contents Index to Financial Statements Restricted Stock Units. Depending on the specific terms of each award, restricted stock units generally vest ratably over the life of the award, usually three years, on each anniversary date of the original grant. Compensation expense for restricted stock units is recognized between the grant date and the vesting date (or the date on which a participant becomes Retirement-eligible, if sooner) on a straight-line basis for each tranche of each award. Fair values of restricted stock units are determined using the closing price of our common stock on the respective dates of grant. Restricted stock unit activity under the 2006 Plan is summarized below. Restricted stock units Weighted average grant date fair value per unit Weighted average remaining contractual term (years) Aggregate intrinsic value (millions) Outstanding at September 30, 2018 481,562 $ 12.14 1.0 Granted 233,830 10.10 Vested ( 259,107 ) 11.75 $ 2.6 Cancelled ( 19,263 ) 11.43 Outstanding at September 30, 2019 437,022 11.31 0.9 Granted 301,979 11.55 Vested ( 295,241 ) 11.40 $ 3.4 Cancelled ( 35,254 ) 11.48 Outstanding at September 30, 2020 408,506 11.41 0.9 Granted 220,795 12.29 Vested ( 228,121 ) 11.62 $ 2.8 Cancelled ( 5,083 ) 11.41 Outstanding at September 30, 2021 396,097 $ 11.78 0.8 Performance-Based Awards. Our performance-based awards consist of performance-based restricted stock units (“PRSUs”). PRSUs represent a target number of units that may be paid out at the end of a multi-year award cycle consisting of annual performance periods coinciding with our fiscal years. As determined at the date of award, PRSUs may settle in cash-value equivalent of, or directly in, shares of our common stock. Settlement will range from zero to two times the number of PRSUs granted, depending on our financial performance against predetermined targets. The grant date for each year’s performance period is set when the Compensation Committee establishes performance goals for the period, normally within 90 days of the beginning of each performance period. At the end of each annual performance period, the Compensation Committee confirms performance against the applicable performance targets. PRSUs do not convey voting rights or earn dividends. PRSUs vest on the last day of an award cycle, unless vested sooner as a result of a “Change of Control” of the Company, or the death, disability or Retirement of a participant. We recognize compensation expense for stock-settled PRSUs starting on the first day of the applicable performance period and ending on the respective vesting dates. We base the recognized compensation expense upon the number of units awarded for each performance period, the closing price of our common stock on the grant date and the estimated performance factor. In 2021 and 2020, 103,058 shares and 93,647 shares, respectively, vested related to PRSUs.

Our market-based awards consist of market-based restricted stock units (“MRSUs”). MRSUs represent a target number of units that may be paid out at the end of a three-fiscal year award cycle based on a calculation of our relative total shareholder return (“TSR”) performance as compared with the TSRs of a selected peer group. Settlements in our common shares, will range from zero to two times the number of MRSUs granted, depending on our TSR performance ranking within the peer group. The fair values of MRSUs are fixed at the date of grant and the related expense is recognized ratably over the vesting period, which is roughly three years from the date of grant. The table below provides information regarding MRSU awards, which were valued using Monte Carlo simulations on the grant date.

The risk-free interest rate is based on the United States Treasury zero-coupon yield in effect at the grant date with a term equal to the expected term. The expected term represents the average period of time the options are expected to be outstanding. Stock option activity under the 2006 Plan is summarized below.

The Mueller Water Products, Inc. 2006 Employee Stock Purchase Plan (“ESPP”) authorizes the sale of up to 5,800,000 shares of our common stock to employees. Generally, all full-time, active employees are eligible to participate in the ESPP, subject to certain restrictions. Employee purchases are funded through payroll deductions, and any excess payroll withholdings are returned to the employee. The price for shares purchased under the ESPP is 85 % of the lower of the closing price on the first day or the last day of the offering period. At September 30, 2021, 2,254,023 shares were available for issuance under the ESPP. F- 33 Table of Contents Index to Financial Statements Phantom Plan. Under the Mueller Water Products, Inc. Phantom Plan adopted in 2012 (“Phantom Plan”), we have awarded “phantom units” to certain non-officer employees. A phantom unit settles in cash equal to the price of one share of our common stock on the vesting date. Phantom units vest ratably over three years on each anniversary date of the original grant. We recognize compensation expense for phantom units on a straight-line basis for each tranche of each award based on the closing price of our common stock at each balance sheet date. The outstanding phantom units had a fair value of $ 15.22 per unit at September 30, 2021 and our accrued liability for such units was $ 3.5 million. Phantom Plan activity is summarized below.

The CARES Act is a relief package intended to assist in many aspects of the American economy through direct secured loans and deferrals of the employer portion of social security taxes through the end of calendar year 2020, with 50% of the deferral due December 31, 2021 and the remainder due December 31, 2022. For the fiscal year ended September 30, 2021, we have elected to defer these obligations, which are approximately $7.2 million as shown above. F- 36 Table of Contents Index to Financial Statements Note 14. Supplemental Statement of Operations Information Between November 2019 and March 2021, we announced the purchase and closure of several facilities. We purchased a new facility in Kimball, Tennessee, to support and enhance our investment in our Chattanooga, Tennessee large casting foundry and closed our facilities in Hammond, Indiana and Woodland, Washington. We also announced the planned closures of our facilities in Aurora, Illinois and Surrey, British Columbia, Canada. The majority of the activities from these plants will be transferred to our Kimball, Tennessee facility. We expect to substantially complete the Aurora and Surrey facility closures by the third quarter of fiscal year 2022 and expect to incur total expenses related to this restructuring of approximately $ 14.0 million, including termination benefit costs of approximately $ 4.8 million and other associated costs of $ 9.2 million. Of the total $ 14.0 million estimated costs, approximately $ 3.6 million are expected to be non-cash charges. Expenses incurred during the years ended September 30, 2021 and September 30, 2020 were approximately $ 5.6 million and $ 2.5 million, respectively. The $ 5.6 million incurred during fiscal 2021 included approximately $ 3.2 million of termination benefit costs which are included in Strategic reorganization and other charges and approximately $ 2.4 million in inventory write-downs which are included in Cost of sales. On June 15, 2021, we experienced a mass shooting tragedy at our Mueller Co. facility in Albertville, Alabama. The event resulted in the deaths of two employees and injuries to two employees. For the year ended September 30, 2021, we incurred expenses of $ 2.1 million related to this tragedy, which are included in Strategic reorganization and other charges. These amounts are net of anticipated insurance recoveries.

Segment Information Our operations consist of two reportable segments: Infrastructure and Technologies. These segments are organized primarily based on products sold and customers served and are consistent with how the segments are managed, how resources are allocated and how information is used by the chief operating decision maker. Infrastructure manufactures valves for water and gas systems including butterfly, iron gate, tapping, check, knife, plug, automatic control and ball valves and dry-barrel and wet-barrel fire hydrants and pipe repair products. Technologies offers metering, leak detection, pipe condition assessment and other products and services for the water infrastructure industry. Segment results are not reflective of their results on a stand-alone basis. Intersegment sales and transfers are made at selling prices generally intended to cover costs. Infrastructure personnel provide certain administrative services, including management of accounts payable and accounts receivable, without any allocation of cost to Technologies. We do not believe the costs of such administrative services are material to the segment’s results. The determination of segment results excludes certain expenses designated as Corporate because they are not directly attributable to segment operations. Interest expense, loss on early extinguishment of debt and income taxes are not allocated to the segments. Corporate expenses include those costs incurred by our corporate function, such as accounting, treasury, risk management, human resources, legal, tax and other administrative functions and also costs associated with assets and liabilities retained following the sales of U.S. Pipe and Anvil. Corporate assets principally consist of our cash, operating lease assets, and certain real property previously owned by U.S. Pipe and Anvil. Business segment assets consist primarily of receivables, inventories, property, plant and equipment, intangible assets and other noncurrent assets. Our largest customers are Ferguson and Core & Main. Information regarding concentrations of our net sales and accounts receivable is presented below. 2021 2020 2019 Percentage of gross revenue: 10 largest customers 58 % 53 % 53 % 2 largest customers 37 % 34 % 34 % Ferguson percentage of gross revenue: Consolidated 19 % 17 % 18 % Infrastructure 18 % 16 % 17 % Technologies 33 % 22 % 30 % Core & Main percentage of gross revenue: Consolidated 18 % 17 % 16 % Infrastructure 20 % 19 % 18 % F- 38 Table of Contents Index to Financial Statements September 30, 2021 2020 (in millions) Customer receivables: Core & Main $ 48.1 $ 37.1 Ferguson 32.1 26.1 Geographical area information is presented below.

Commitments and Contingencies We are involved in various legal proceedings that have arisen in the normal course of operations, including the proceedings summarized below. The effect of the outcome of these matters on our financial statements cannot be predicted with certainty as any such effect depends on the amount and timing of the resolution of such matters and potential insurance coverage. Other than the litigation described below, we do not believe that any of our outstanding litigation would have a material adverse effect on our business or prospects. Environmental. We are subject to a wide variety of laws and regulations concerning the protection of the environment, both with respect to the operations at many of our properties and with respect to remediating environmental conditions that may exist at our own or other properties. We accrue for environmental expenses resulting from existing conditions that relate to past operations when the costs are probable and reasonably estimable. Under the terms of the acquisition agreement relating to the August 1999 sale by Tyco of businesses which make up certain of the companies within Mueller Water Products, Inc., we are indemnified by certain Tyco entities for, among other things, all “Excluded Liabilities.” Excluded Liabilities include, among other things, substantially all liabilities relating to the time prior to August 1999, including environmental liabilities. The indemnity survives indefinitely. Tyco’s indemnity does not cover liabilities to the extent caused by us or the operation of our businesses after August 1999, nor does it cover liabilities arising with respect to businesses or sites acquired after August 1999. Since 2007, Tyco has engaged in multiple corporate restructurings, split-offs and divestitures. While none of these transactions directly affects the indemnification obligations of the Tyco indemnitors under the 1999 acquisition agreement, the result of such transactions is that the assets of, and control F- 40 Table of Contents Index to Financial Statements over, such Tyco indemnitors has changed. Should any of these Tyco indemnitors become financially unable or fail to comply with the terms of the indemnity, we may be responsible for such obligations or liabilities. On July 13, 2010, Rohcan Investments Limited, the former owner of property leased by Mueller Canada Ltd. and located in Milton, Ontario, filed suit against Mueller Canada Ltd. and its directors seeking C$ 10.0 million in damages arising from the defendants’ alleged environmental contamination of the property and breach of lease. Mueller Canada Ltd. leased the property from 1988 through 2008. We are pursuing indemnification from a former owner for certain potential liabilities that are alleged in this lawsuit, and we have accrued for other liabilities not covered by indemnification. On December 7, 2011, the Court denied the plaintiff’s motion for summary judgment. The purchaser of U.S. Pipe has been identified as a “potentially responsible party” (“PRP”) under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) in connection with a former manufacturing facility operated by U.S. Pipe that was in the vicinity of a proposed Superfund site located in North Birmingham, Alabama. Under the terms of the acquisition agreement relating to our sale of U.S. Pipe, we agreed to indemnify the purchaser for certain environmental liabilities, including those arising out of the former manufacturing site in North Birmingham. Accordingly, the purchaser tendered the matter to us for indemnification, which we accepted. Ultimate liability for the site will depend on many factors that have not yet been determined, including the determination of EPA’s remediation costs, the number and financial viability of the other PRPs (there are four other PRPs currently) and the determination of the final allocation of the costs among the PRPs. Accordingly, because the amount of such costs cannot be reasonably estimated at this time, no amounts had been accrued for this matter at September 30, 2021. Walter Energy . We were a member of the Walter Energy, Inc (“Walter Energy”) federal tax consolidated group through December 14, 2006, at which time the Company was spun-off from Walter Energy. Accordingly, we were jointly and severally liable for the federal income tax liability, if any, of the consolidated group for each of those years. As a result of a proof of claim filed by the IRS against Walter Energy in its 2015 bankruptcy case, we paid $ 22.2 million, including additional accrued interest, to the IRS in final settlement of this tax dispute. All appeal periods have expired, and our liabilities with respect to the Walter Tax Liability have been fully resolved. The COVID-19 Pandemic. The pandemic has caused, and is likely to continue to cause, severe economic, market and other disruptions to the United States and global economies. As a result of the pandemic, we experienced adverse business conditions during the year, including significant costs to mitigate the pandemic effects. During the course of the pandemic, we have taken steps, as reasonably necessary, to maximize liquidity by limiting cash expenditures, including furloughing significant numbers of our employees, implementing temporary shutdowns of our manufacturing facilities or portions of our manufacturing facilities, implementing temporary salary reductions for our senior leadership team, deferral of capital expenditures, reduced fees for our Board of Directors and aggressively reducing general and administrative spending. We will continue to take steps as necessary. We are uncertain of the potential full magnitude or duration of the business and economic impacts from the unprecedented public health effort to contain and combat the spread of COVID-19, and while the extent to which the pandemic affects our results will depend on future developments, the outbreak could result in material effects to our future financial position, results of operations, cash flows and liquidity. Mass Shooting Event at our Mueller Co. Facility in Albertville, Alabama . On June 15, 2021, we experienced a mass shooting event at our Mueller Co. facility in Albertville, Alabama, in which two employees were killed and two employees were injured. Various workers’ compensation claims arising from the event have been made to date, and we anticipate that additional claims may be made, and that liability under such claims, if any, is not expected to have a material adverse effect on our results of operations or cash flows. However, the possibility of other legal proceedings, and any related effects, arising from this event cannot be predicted with certainty. Indemnifications . We are a party to contracts in which it is common for us to agree to indemnify third parties for certain liabilities that arise out of or relate to the subject matter of the contract. In some cases, this indemnity extends to related liabilities arising from the negligence of the indemnified parties, but usually excludes any liabilities caused by gross negligence or willful misconduct. We cannot estimate the potential amount of future payments under these indemnities until events arise that would trigger a liability under the indemnities. Additionally, in connection with the sale of assets and the divestiture of businesses, such as the divestitures of U.S. Pipe and Anvil, we may agree to indemnify buyers and related parties for certain losses or liabilities incurred by these parties with respect to: (i) the representations and warranties made by us to these parties in connection with the sale and (ii) liabilities related to the pre-closing operations of the assets or business sold. Indemnities related to pre-closing operations generally include certain environmental and tax liabilities and other liabilities not assumed by these parties in the transaction. F- 41 Table of Contents Index to Financial Statements Indemnities related to the pre-closing operations of sold assets or businesses normally do not represent additional liabilities to us, but simply serve to protect these parties from potential liability associated with our obligations existing at the time of the sale. As with any liability, we have accrued for those pre-closing obligations that are considered probable and reasonably estimable. Should circumstances change, increasing the likelihood of payments related to a specific indemnity, we will accrue a liability when future payment is probable and the amount is reasonably estimable. Other Matters. We monitor and analyze our warranty experience and costs periodically and may revise our warranty accruals as necessary. Critical factors in our reserve analyses include warranty terms, specific claim situations, incurred and projected failure rates, the nature of product failures, product and labor costs, and general business conditions. We are party to a number of other lawsuits arising in the ordinary course of business, including product liability cases for products manufactured by us or third parties. While the results of litigation cannot be predicted with certainty, we believe that the final outcome of such other litigation is not likely to have a material adverse effect on our business or prospects. Note 18. Subsequent Events On October 22, 2021 , our Board of Directors declared a dividend of $ 0.0580 per share on our common stock, a 5.5% increase from the prior quarter, payable on or about November 22, 2021 to stockholders of record at the close of business on November 10, 2021 . Additionally, we announced a new management structure effective October 1, 2021. The new structure is designed to increase revenue growth, drive operational excellence, accelerate new product development and enhance profitability. We anticipate the reorganization will strengthen the alignment of products, solutions and services with customer needs, accelerate new product introductions and improve product life cycle management. The two newly named business units are Water Flow Solutions and Water Management Solutions. • Water Flow Solutions’ product portfolio includes iron gate valves, specialty valves and service brass products. Net sales of products in the Water Flow Solutions business unit were approximately 60% of fiscal 2021 consolidated net sales. • Water Management Solutions’ product and service portfolio includes fire hydrants, repair and installation, natural gas, metering, leak detection, pressure control and software products. Net sales of products in the Water Management Solutions business unit were approximately 40% of fiscal 2021 consolidated net sales. F- 42
