MUELLER WATER PRODUCTS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE THREE AND NINE MONTHS ENDED JUNE 30, 2022

(UNAUDITED)

Note 1. Organization and Basis of Presentation

Mueller Water Products, Inc., a Delaware corporation, together with its consolidated subsidiaries, operates in two business segments: Water Flow Solutions and Water Management Solutions. These segments are based on a management reorganization that became effective October 1, 2021; prior period information has been recast to conform to the current presentation. Water Flow Solutions’ product portfolio includes iron gate valves, specialty valves and service brass products. Water Management Solutions’ product and service portfolio includes fire hydrants, repair and installation, natural gas, metering, leak detection, pressure control and software products. The “Company,” “we,” “us” or “our” refer to Mueller Water Products, Inc. and its subsidiaries, and may also refer to the segment being discussed.

On December 3, 2018, we completed our acquisition of Krausz Industries Development Ltd. and subsidiaries (“Krausz”). During the year ended September 30, 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 included the preliminary estimated fair values of the net assets of i2O. The accounting for this business combination became final during the three months ended March 31, 2022. The results of i2O’s operations and cash flows subsequent to the acquisition are included in the Company’s consolidated statement of operations and consolidated statement of cash flows, respectively. Refer to Note 2. 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 in recording assets, liabilities, sales and expenses as well as in the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. All significant intercompany balances and transactions have been eliminated. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the year ended September 30, 2021. In our opinion, all normal and recurring adjustments that we consider necessary for a fair financial statement presentation have been made. The condensed consolidated balance sheet at September 30, 2021 was derived from audited financial statements, but it does not include all disclosures required by GAAP.

Our business is seasonal as a result of cold weather conditions. Net sales and operating income historically have been lowest in the three month periods ending December 31 and March 31 when the northern United States and all of Canada generally face weather conditions that restrict significant construction activity.

In preparing these financial statements in conformity with GAAP, we have considered and, where appropriate, included the effects of the COVID-19 pandemic on our operations. The pandemic continues to provide significant challenges to the U.S. and global economies.

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.

Recently Adopted Accounting Guidance

During 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Codification (“ASC”) 326 - Current Expected Credit Losses to replace the “incurred loss” impairment approach with an “expected loss” approach, which requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. We completed historical and forward-looking analyses for receivables and adopted this guidance effective October 1, 2020. Upon adoption, there was no material impact to our financial statements.

9

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 was 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 adopted this standard on October 1, 2021 and there was no material impact to 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”). This 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 may be adopted prospectively from a date within an interim period subsequent to March 12, 2020. We evaluated our contracts and the optional expedients provided by ASU 2020-04. We adopted this standard on October 1, 2021 and there was no material impact to our financial statements.

Restructuring

Since November 2019, we have 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, Woodland, Washington and Surrey, British Columbia, Canada. We also announced the closure of our facility in Aurora, Illinois which we expect to complete substantially by the end of fiscal 2022. The majority of the activities from these facilities have been transferred to our Kimball, Tennessee facility. In connection with these reorganizations, we recognized certain restructuring costs. Activity in accrued restructuring, reported as part of Other current liabilities, is presented below.

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 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.

10

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 underlying 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 within Other noncurrent liabilities as a result of its redemption features.

Direct costs associated with Wells Fargo’s capital contribution were 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 are being 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.    Acquisitions

Acquisition of i2O Water Ltd

On June 14, 2021, we acquired all the outstanding capital stock of i2O for $19.7 million, net of cash acquired. The purchase agreement provided for customary final adjustments, including a net working capital adjustment that was completed during the three months ended December 31, 2021, resulting in a purchase price of $19.5 million.

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 final. The results of i2O are included in our Water Management Solutions 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. 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.

The following is a summary of the 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	(1.3)
Fair value of net assets acquired, net of cash	$	19.5

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

We disaggregate our revenue from contracts with customers by reportable segment (see Note 10.) and further by geographical region as we believe this 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 (i.e., 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 we expect to receive within one year and therefore is included within Other current liabilities in the accompanying consolidated balance sheets. Deferred revenue represents contract liabilities and are recorded when customers remit cash payments in advance of our satisfaction of performance obligations under contractual arrangements. Contract liabilities are relieved and revenue is recognized when the performance obligation is satisfied.

The table below represents the balances of our customer receivables and deferred revenue.

	June 30,		September 30,
	2022		2021
	(in millions)
Billed receivables	$	224.3	$	213.4
Unbilled receivables	2.4		2.3
Gross customer receivables	226.7		215.7
Allowance for credit losses	(4.8)		(3.5)
Receivables, net	$	221.9	$	212.2
Deferred revenue	$	8.2	$	5.4

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 for sales of product or over time for 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 based typically on historical experience and known trends. We do not recognize variable consideration in the event there are uncertainties in the amount of variable consideration to be paid nor when it is probable there will be a significant reversal in the related revenue.

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 sales.

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.

12

The revenue recognized at a point in time related to the sale of our products is 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.

We offer warranties that 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.

Note 4. Income Taxes

The reconciliation between the U.S. federal statutory income tax rate and the effective income tax rate is presented below.

	Three months ended				Nine months ended

ABL Agreement. Our asset-based lending agreement (“ABL Agreement”) consists of a revolving credit facility for up to $175.0 million which includes up to $25.0 million of swing line loans and may have up to $60.0 million of letters of credit. The ABL Agreement permits us to increase the size of the credit facility by an additional $150.0 million in certain circumstances subject to adequate borrowing base availability.

13

Borrowings under the 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 June 30, 2022 the applicable margin for LIBOR based loans was 200 basis points and for base rate loans was 100 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 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 inventories, accounts receivable, certain cash and other related items.

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 or 10% of the Loan Cap as defined in the ABL Agreement. Excess availability based on June 30, 2022 data was $160.7 million, as reduced by $14.1 million of outstanding letters of credit and $0.2 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 Unsecured Notes (“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. Substantially all of our U.S. subsidiaries guarantee the 4.0% Senior Notes that are subordinate to borrowings under our ABL Agreement. Based on quoted market prices that are a Level 1 measurement, the outstanding 4.0% Senior Notes had a fair value of $392.8 million at June 30, 2022.

An indenture governing 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 June 30, 2022.

As set forth in the Indenture, we may redeem some or all of the 4.0% Senior Notes at any 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 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.

Note 6. 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 had no direct effect on our consolidated financial statements, it created exposure to currency risk for the Canadian subsidiary. To reduce this exposure, we entered into a U.S. dollar-Canadian dollar swap contract with the Canadian subsidiary and an offsetting Canadian dollar-U.S. dollar swap with a domestic bank. We did not designate these swaps as hedges and the changes in their fair value were included in earnings, offsetting the currency gains and losses associated with the intercompany loan.

The value of our currency swap contracts as of September 30, 2021 was a liability of $1.1 million, and was included in Other current liabilities. The currency swap contracts expired in February 2022.

Note 7. Retirement Plans

The components of net periodic benefit cost for our pension plans are presented below.

	Three months ended				Nine months ended

Net periodic benefit	$	(0.6)	$	(0.4)	$	(2.0)	$	(1.2)

The amortization of actuarial losses, net of tax, is recorded as a component of other comprehensive income (loss).

Note 8. Stock-based Compensation Plans

We grant various forms of stock-based compensation, including market-based restricted stock units (“MRSUs”), restricted stock units, stock options and performance-based restricted stock units (“PRSUs”) under our Amended and Restated 2006 Mueller Water Products, Inc. Stock Incentive Plan (the “2006 Stock Plan”), Phantom Plan instruments under our Mueller Water Products, Inc. 2012 Phantom Plan, and Employee stock purchase plan instruments under our 2006 Employee Stock Purchase Plan. Grants issued during the nine months ended June 30, 2022 are as follows:

	Number granted	Weighted average grant date fair value per instrument		Total grant date fair value (in millions)
Quarter ended December 31, 2021
MRSUs	230,089	$	15.76	$	3.6
Phantom Plan instruments	199,549	13.64		2.7

An MRSU award represents a target number of units that may be paid out at the end of a three-year award cycle based on a calculation of our relative total shareholder return (“TSR”) performance as compared with the TSR 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 relative to that of the peer group.

15

Compensation expense attributed to MRSUs is based on the fair value of the awards on their respective grant dates, as determined using a Monte Carlo model. The assumptions used to determine the grant date fair value are indicated below.

	November 30, 2021
Variables used in determining grant date fair value:
Dividend yield	1.70	%
Risk-free rate	0.76	%
Expected term (in years)	2.83

The expected dividend yield is based on our estimated annual dividend and our stock price history at the grant date. The risk-free interest rate is based on the U.S. 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 units are expected to be outstanding.

At June 30, 2022, the outstanding Phantom Plan instruments had a fair value of $11.73 per instrument and our liability for Phantom Plan instruments was $2.5 million and is included within Other current and Other noncurrent liabilities.

Stock options generally vest ratably over three years on each anniversary date. Compensation expense attributed to stock options is based on the fair value of the awards on their respective grant dates, using a Black-Scholes model. The assumptions used to determine the grant date fair value are indicated below.

	November 30, 2021
Dividend yield	1.62	%
Risk-free rate	1.33	%
Expected term (in years)	6.00

The expected dividend yield is based on our estimated annual dividend and our stock price history at the grant date. The risk-free interest rate is based on the U.S. 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.

A PRSU award consists of a number of units that may be paid out at the end of a three-year award cycle consisting of a series of annual performance periods coinciding with our fiscal years. After we establish the financial performance targets related to PRSUs for a given performance period, typically during the first quarter of that fiscal year, we consider that portion of a PRSU award to be granted. Thus, each award consists of a grant in the year of award and grants in the two following years. Settlements, in our common shares, will range from zero to two times the number of PRSUs granted, depending on our financial performance relative to the targets.

We did not issue any shares of common stock to settle PRSUs vested during the three months ended June 30, 2022; however, we issued 240,412 shares of common stock to settle PRSUs vested during the nine months ended June 30, 2022. Additionally, we issued 3,716 and 238,811 shares of common stock to settle restricted stock units vested during the three and nine months ended June 30, 2022, respectively. Finally, we issued no shares of common stock to settle stock options exercised during the three months ended June 30, 2022; however, we issued 24,153 shares of common stock to settle stock options exercised during the nine months ended June 30, 2022.

Operating income included stock-based compensation expense of $2.5 million and $3.4 million for the three months ended June 30, 2022 and 2021, respectively. Operating income included stock-based compensation expense of $7.6 million and $8.4 million during the nine months ended June 30, 2022 and 2021, respectively. At June 30, 2022, there was approximately $10.5 million of unrecognized compensation expense related to stock-based compensation arrangements and there were 53,067 PRSUs that have been awarded for the 2022 performance period for which performance goal achievement cannot yet be determined.

We excluded 892,662 and 131,178 stock-based compensation instruments from the calculations of diluted earnings per share in the three months ended June 30, 2022 and 2021, respectively, and 750,343 and 566,666 for the nine months ended June 30, 2022 and 2021, respectively, since their inclusion would have been antidilutive.

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 1st 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.

The following table summarizes information concerning our goodwill balance in the nine months ended June 30, 2022, in millions.

Note 12. Commitments and Contingencies

We are involved in various legal proceedings that have arisen in the normal course of operations, including the proceedings summarized below. We provide for costs relating to these matters when a loss is probable and the amount is reasonably estimable. Legal costs related to these matters are expensed as incurred. 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. Other than the litigation described below, we do not believe that any of our outstanding litigation would have a materially adverse effect on our financial position, results of operations, cash flows or liquidity.

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.

In the acquisition agreement pursuant to which a predecessor to Tyco International plc, now Johnson Controls International plc (“Tyco”), sold our businesses to a previous owner in August 1999, Tyco agreed to indemnify us and our affiliates, among other things, for 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 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 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 the Environmental Protection Agency’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. Since the amounts of such costs cannot be reasonably estimated at this time, no amounts have been accrued for this matter at June 30, 2022.

20

The COVID-19 Pandemic. The pandemic has caused, and is likely to continue to cause, severe economic, market and other disruptions to the U.S. and global economies. We have taken action and continue to counter such disruption, and work to protect the safety of our employees. While the extent to which the pandemic affects our results will depend on future developments, the pandemic 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 claims arising from the event have been filed 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 outcome of these claims, or legal proceedings, and 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.

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 accruals as necessary. Critical factors in our 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. During the three months ended June 30, 2022, we recorded $4.5 million of warranty obligations.

We are party to a number of 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 materially adverse effect on our financial position, results of operations, cash flows or liquidity.

Item 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto that appear elsewhere in this report. This report 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, trend descriptions, environmental/sustainability plans, go-to-market strategies, operational excellence, acceleration of new product development, financial or operating performance, litigation outcomes, capital allocation and growth strategy plans, restructuring efficiencies and projected warranty charges. 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, 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 related to the COVID-19 pandemic, 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, 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.

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.

Overview

Business

We estimate approximately 55-60% of our 2021 net sales were for repair and replacement directly related to municipal water infrastructure spending, approximately 30-35% were related to residential construction activity and less than 10% were related to natural gas utilities spending.

We expect the operating environment during fiscal year 2022 to be very challenging as a result of the uncertainty around the depth and duration of the pandemic which has accelerated and may continue to accelerate, inflation, labor availability and global supply chain disruptions. We anticipate healthy demand in the municipal repair and replacement market due to favorable budgets, especially at larger municipalities. While demand from the new residential construction end market has been at healthy levels during the first half of calendar 2022, especially for lot and land development activity, we anticipate that activity levels will slow for the rest of the year based on higher interest rates leading to a decrease in demand for new residential housing. In July 2022, Blue Chip Economic Indicators forecasted housing growth of 0.9% for calendar 2022 as compared with the prior year.

We have continued to incur additional costs to address the pandemic as discussed herein, including costs associated with unfavorable manufacturing variances, labor shortages, and additional cleaning, including disinfectants and sanitation materials, for our employees and at our facilities. We expect to continue to incur such costs that may be significant as we continue to respond to the pandemic. All of our facilities are operational and our teams have worked effectively to address the few temporary closures we have experienced due to the pandemic. The last such closure was in August 2020. The pandemic also

22

caused supply chain disruption that has resulted in higher costs in the manufacture of our products. We expect these conditions to persist in the near term and may worsen until the pandemic abates.

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 and reportable segments are Water Flow Solutions and Water Management Solutions.

Water Flow Solutions’ product portfolio includes iron gate valves, specialty valves and service brass products. Water Flow Solutions represented 56% of our fiscal 2021 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. Water Management Solutions represented 44% of our fiscal 2021 net sales.

Consolidated Analysis

Net sales in the three months ended June 30, 2022 increased $22.7 million or 7.3% to $333.2 million as compared with $310.5 million in the prior period primarily as a result of higher pricing across most of our product lines, which was partially offset by lower shipment volumes.

Gross profit in the three months ended June 30, 2022 decreased $7.1 million or 6.7% to $98.3 million from $105.4 million in the prior year period, primarily as a result of unfavorable manufacturing performance, higher costs associated with inflation, lower shipment volumes on certain products, and an increase in our warranty obligations which were partially offset by higher pricing across most of our product lines. Gross margin was 29.5% in the three months ended June 30, 2022 as compared with 33.9% in the prior year period.

24

Selling, general and administrative expenses (“SG&A”) in the three months ended June 30, 2022 increased $2.0 million to $60.8 million from $58.8 million in the prior year period primarily as a result of inflation and travel and trade show expenditures, partially offset by foreign exchange gains. SG&A as a percentage of net sales was 18.2% and 18.9% for the three months ended June 30, 2022 and June 30, 2021, respectively.

Strategic reorganization and other charges in the three months ended June 30, 2022 were $0.6 million which primarily consisted of restructuring expenses including costs associated with the closures of our facilities in Aurora, Illinois, and Surrey, British Columbia, Canada. Strategic reorganization and other charges for the three months ended June 30, 2021 were $3.9 million, which primarily consisted of expenses associated with the Albertville tragedy, as well as termination benefits associated with the closures of our facilities in Aurora, Illinois and Surrey, British Columbia, Canada and acquisition transaction costs.

Interest expense, net declined $2.6 million in the three months ended June 30, 2022 as compared with the prior year period primarily as a result of the refinancing of our 5.5% Senior Unsecured Notes (“5.5% Senior Notes”) with the 4.0% Senior Notes in May, 2021.

Consolidated Analysis

Net sales in the nine months ended June 30, 2022 increased $100.6 million or 12.3% to $916.0 million as compared with $815.4 million in the prior period primarily as a result of higher pricing across most of our product lines and increased shipment volumes.

Gross profit in the nine months ended June 30, 2022 increased $6.5 million to $278.7 million from $272.2 million in the prior year period, primarily as a result of higher pricing and increased shipment volumes which were partially offset by higher costs of sales associated with inflation, unfavorable manufacturing performance including labor challenges, supply chain disruptions, and an increase in our warranty obligations. Gross margin was 30.4% in the nine months ended June 30, 2022 as compared with 33.4% in the prior year period.

27

SG&A in the nine months ended June 30, 2022 increased $12.9 million to $175.1 million from $162.2 million in the prior year period primarily as a result of higher travel and trade show expenditures, higher costs associated with inflation, investments in engineering and information technology and the inclusion of i2O Water, partially offset by foreign exchange gains.

Liquidity and Capital Resources

We had cash and cash equivalents on hand of $154.9 million at June 30, 2022 and $160.7 million of additional borrowing capacity under our ABL Agreement based on June 30, 2022 data. Undistributed earnings from our subsidiaries in Canada, China, and Israel are considered to be permanently invested outside the United States. At June 30, 2022, cash and cash equivalents included $42.1 million, $13.7 million, and $6.3 million in Israel, Canada, and China, respectively.

We declared a quarterly dividend of $0.058 per share on July 27, 2022, payable on or about August 22, 2022 to holders of record as of August 10, 2022, which will result in an estimated $9.1 million cash outlay.

We repurchased $25.0 million of our outstanding common stock during the nine months ended June 30, 2022 and had $110.0 million remaining of our share repurchase authorization.

The ABL Agreement and 4.0% Senior Notes contain customary representations and warranties, covenants and provisions governing an event of default.  The covenants restrict our ability to engage in certain specified activities, including but not limited to the payment of dividends and the redemption of our common stock.

29

Collections from customers were higher during the nine months ended June 30, 2022 as compared with the prior year period primarily as a result of net sales growth between the periods. Inventory purchases increased during the nine months ended June 30, 2022 as compared with the nine months ended June 30, 2021 as a result of inflation, increased sales volume and supply change management. Other current liabilities and other noncurrent liabilities decreased as a result of employee incentive payouts, income tax payments, the repayment of the CARES Act employer payroll tax deferral and the payment of customer rebates.

Capital expenditures were $36.7 million in the nine months ended June 30, 2022 as compared with $46.1 million in the prior year period. Capital expenditures decreased primarily as a result of lower expenditures associated with the new Decatur foundry as compared with the prior year period. For fiscal year 2022, we have provided guidance that our capital expenditures are expected to be between $50.0 million and $55.0 million.

We anticipate that our existing cash, cash equivalents and borrowing capacity combined with our expected operating cash flows will be sufficient to meet our anticipated operating expenses, income tax payments, capital expenditures and debt service obligations as they become due through June 30, 2023.

We believe that additional borrowings through various financing alternatives remain available if required. The future effects of the pandemic cannot be predicted with certainty and may increase our borrowing costs and other costs of capital or otherwise adversely affect our financial condition and liquidity, and we cannot guarantee that we will have access to external financing at times and on terms we consider acceptable, or at all, or that we will not experience other liquidity issues in the future.

ABL Agreement

At June 30, 2022, the ABL Agreement consisted of a $175.0 million revolving credit facility which includes up to $25.0 million of swing line loans and may have up to $60.0 million of letters of credit. The ABL Agreement permits us to increase the size of the credit facility by an additional $150.0 million in certain circumstances subject to adequate borrowing base availability.

Borrowings under the ABL Agreement bear interest at a floating rate equal to LIBOR, plus an applicable margin ranging from 200 to 225 basis points, or a base rate, as defined in the ABL Agreement, plus an applicable margin ranging from 100 to 125 basis points. At June 30, 2022, the applicable margin for LIBOR was 200 basis points and for base rate loans was 100 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 inventories or (ii) 85% of the net orderly liquidation value of eligible inventory, less certain reserves. Prepayments can be made at any time with no penalty.

Substantially all of our U.S. 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 U.S. inventories, accounts receivable, certain cash and other related items.

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 or 10% of the Loan Cap as defined in the ABL Agreement. Excess availability based on June 30, 2022 data was $160.7 million, as reduced by $14.1 million of outstanding letters of credit and $0.2 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 Unsecured Notes (“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 previously existing 5.5% Senior Notes. Substantially all of our U.S. subsidiaries guarantee the 4.0% Senior Notes, which are subordinate to borrowings under our ABL Agreement. Based on quoted market prices the outstanding 4.0% Senior Notes had a fair value of $392.8 million at June 30, 2022.

30

An indenture governing 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 June 30, 2022.

As set forth in the Indenture, we may redeem some or all of the 4.0% Senior Notes at any 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 prior to June 15, 2024 with the net proceeds of specified equity offerings at specified redemption prices. Upon a change in 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 2026 and bore interest at 5.5%, paid semi-annually. We called the 5.5% Senior Notes effective June 17, 2021 and settled with proceeds from the issuance of 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 associated with the retirement of the 5.5% Senior Notes.

Our corporate credit rating and the credit rating for our debt are presented below. These ratings are not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agencies.

Material Cash Requirements

We enter into a variety of contractual obligations as part of our normal operations in addition to capital expenditures. As of June 30, 2022, we have (i) debt obligations related to our $450.0 million 4.0% Senior Notes which mature in 2029 and include cash interest payments of $18.9 million in 2022 and $18.0 million annually thereafter through 2029, (ii) cash obligations of $33.5 million for operating leases through 2033 and $1.9 million for finance leases through 2026, and (iii) purchase obligations for raw materials and other parts of approximately $163.1 million which we expect to incur during the next 12 months. We expect to fund these cash requirements from cash on hand and cash generated from operations.

Off-Balance Sheet Arrangements

We do not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as “structured finance” or “special purpose” entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, at June 30, 2022 we did not have any undisclosed borrowings, debt, derivative contracts or synthetic leases. Therefore, we were not exposed to any financing, liquidity, market or credit risk that could have arisen had we engaged in such relationships.

We use letters of credit and surety bonds in the ordinary course of business to ensure the performance of contractual obligations. At June 30, 2022, we had $14.1 million of letters of credit and $33.1 million of surety bonds outstanding.

Seasonality

Our business is seasonal as a result of the impact of cold weather conditions. Net sales and operating income historically have been lowest in the three month periods ending December 31 and March 31 when the northern United States and all of Canada generally face weather conditions that restrict significant construction activity.

Item 4.    CONTROLS AND PROCEDURES

There have been no changes in our internal control over financial reporting which have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting during the quarter ended June 30, 2022.

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 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 our Chief Financial Officer have concluded, based on an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) by our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, that such disclosure controls and procedures were effective as of the end of the period covered by this report.

Our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls can prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. There are inherent limitations in all control systems, including the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of one or more persons. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and, while our disclosure controls and procedures are designed to be effective under circumstances where they should reasonably be expected to operate effectively, there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Because of the inherent limitations in any control system, misstatements due to error or fraud may occur and not be detected.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization

Organization and Basis of Presentation

Mueller Water Products, Inc., a Delaware corporation, together with its consolidated subsidiaries, operates in two business segments: Water Flow Solutions and Water Management Solutions. These segments are based on a management reorganization that became effective October 1, 2021; prior period information has been recast to conform to the current presentation. Water Flow Solutions’ product portfolio includes iron gate valves, specialty valves and service brass products. Water Management Solutions’ product and service portfolio includes fire hydrants, repair and installation, natural gas, metering, leak detection, pressure control and software products. The “Company,” “we,” “us” or “our” refer to Mueller Water Products, Inc. and its subsidiaries, and may also refer to the segment being discussed.

On December 3, 2018, we completed our acquisition of Krausz Industries Development Ltd. and subsidiaries (“Krausz”). During the year ended September 30, 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 included the preliminary estimated fair values of the net assets of i2O. The accounting for this business combination became final during the three months ended March 31, 2022. The results of i2O’s operations and cash flows subsequent to the acquisition are included in the Company’s consolidated statement of operations and consolidated statement of cash flows, respectively. Refer to Note 2. 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 in recording assets, liabilities, sales and expenses as well as in the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. All significant intercompany balances and transactions have been eliminated. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the year ended September 30, 2021. In our opinion, all normal and recurring adjustments that we consider necessary for a fair financial statement presentation have been made. The condensed consolidated balance sheet at September 30, 2021 was derived from audited financial statements, but it does not include all disclosures required by GAAP.

Our business is seasonal as a result of cold weather conditions. Net sales and operating income historically have been lowest in the three month periods ending December 31 and March 31 when the northern United States and all of Canada generally face weather conditions that restrict significant construction activity.

In preparing these financial statements in conformity with GAAP, we have considered and, where appropriate, included the effects of the COVID-19 pandemic on our operations. The pandemic continues to provide significant challenges to the U.S. and global economies.

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.

Recently Adopted Accounting Guidance

During 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Codification (“ASC”) 326 - Current Expected Credit Losses to replace the “incurred loss” impairment approach with an “expected loss” approach, which requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. We completed historical and forward-looking analyses for receivables and adopted this guidance effective October 1, 2020. Upon adoption, there was no material impact to our financial statements.

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 was 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 adopted this standard on October 1, 2021 and there was no material impact to 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”). This 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 may be adopted prospectively from a date within an interim period subsequent to March 12, 2020. We evaluated our contracts and the optional expedients provided by ASU 2020-04. We adopted this standard on October 1, 2021 and there was no material impact to our financial statements.

Restructuring

Since November 2019, we have 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, Woodland, Washington and Surrey, British Columbia, Canada. We also announced the closure of our facility in Aurora, Illinois which we expect to complete substantially by the end of fiscal 2022. The majority of the activities from these facilities have been transferred to our Kimball, Tennessee facility. In connection with these reorganizations, we recognized certain restructuring costs. Activity in accrued restructuring, reported as part of Other current liabilities, is presented below.

Revenue from Contracts with Customers (Notes)

9 Months Ended

Revenue from Contracts with Customers [Abstract]

Revenue from Contract with Customer [Text Block]

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

We disaggregate our revenue from contracts with customers by reportable segment (see Note 10.) and further by geographical region as we believe this 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 (i.e., 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 we expect to receive within one year and therefore is included within Other current liabilities in the accompanying consolidated balance sheets. Deferred revenue represents contract liabilities and are recorded when customers remit cash payments in advance of our satisfaction of performance obligations under contractual arrangements. Contract liabilities are relieved and revenue is recognized when the performance obligation is satisfied.

The table below represents the balances of our customer receivables and deferred revenue.

	June 30,		September 30,
	2022		2021
	(in millions)
Billed receivables	$	224.3	$	213.4
Unbilled receivables	2.4		2.3
Gross customer receivables	226.7		215.7
Allowance for credit losses	(4.8)		(3.5)
Receivables, net	$	221.9	$	212.2
Deferred revenue	$	8.2	$	5.4

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 for sales of product or over time for 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 based typically on historical experience and known trends. We do not recognize variable consideration in the event there are uncertainties in the amount of variable consideration to be paid nor when it is probable there will be a significant reversal in the related revenue.

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 sales.

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.

The revenue recognized at a point in time related to the sale of our products is 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.

We offer warranties that 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.

ABL Agreement. Our asset-based lending agreement (“ABL Agreement”) consists of a revolving credit facility for up to $175.0 million which includes up to $25.0 million of swing line loans and may have up to $60.0 million of letters of credit. The ABL Agreement permits us to increase the size of the credit facility by an additional $150.0 million in certain circumstances subject to adequate borrowing base availability.

Borrowings under the 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 June 30, 2022 the applicable margin for LIBOR based loans was 200 basis points and for base rate loans was 100 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 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 inventories, accounts receivable, certain cash and other related items.

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 or 10% of the Loan Cap as defined in the ABL Agreement. Excess availability based on June 30, 2022 data was $160.7 million, as reduced by $14.1 million of outstanding letters of credit and $0.2 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 Unsecured Notes (“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. Substantially all of our U.S. subsidiaries guarantee the 4.0% Senior Notes that are subordinate to borrowings under our ABL Agreement. Based on quoted market prices that are a Level 1 measurement, the outstanding 4.0% Senior Notes had a fair value of $392.8 million at June 30, 2022.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	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 had no direct effect on our consolidated financial statements, it created exposure to currency risk for the Canadian subsidiary. To reduce this exposure, we entered into a U.S. dollar-Canadian dollar swap contract with the Canadian subsidiary and an offsetting Canadian dollar-U.S. dollar swap with a domestic bank. We did not designate these swaps as hedges and the changes in their fair value were included in earnings, offsetting the currency gains and losses associated with the intercompany loan. The value of our currency swap contracts as of September 30, 2021 was a liability of $1.1 million, and was included in Other current liabilities.

An MRSU award represents a target number of units that may be paid out at the end of a three-year award cycle based on a calculation of our relative total shareholder return (“TSR”) performance as compared with the TSR 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 relative to that of the peer group.

Compensation expense attributed to MRSUs is based on the fair value of the awards on their respective grant dates, as determined using a Monte Carlo model. The assumptions used to determine the grant date fair value are indicated below.

	November 30, 2021
Variables used in determining grant date fair value:
Dividend yield	1.70	%
Risk-free rate	0.76	%
Expected term (in years)	2.83

The expected dividend yield is based on our estimated annual dividend and our stock price history at the grant date. The risk-free interest rate is based on the U.S. 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 units are expected to be outstanding.

At June 30, 2022, the outstanding Phantom Plan instruments had a fair value of $11.73 per instrument and our liability for Phantom Plan instruments was $2.5 million and is included within Other current and Other noncurrent liabilities.

Stock options generally vest ratably over three years on each anniversary date. Compensation expense attributed to stock options is based on the fair value of the awards on their respective grant dates, using a Black-Scholes model. The assumptions used to determine the grant date fair value are indicated below.

	November 30, 2021
Dividend yield	1.62	%
Risk-free rate	1.33	%
Expected term (in years)	6.00

The expected dividend yield is based on our estimated annual dividend and our stock price history at the grant date. The risk-free interest rate is based on the U.S. 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.

A PRSU award consists of a number of units that may be paid out at the end of a three-year award cycle consisting of a series of annual performance periods coinciding with our fiscal years. After we establish the financial performance targets related to PRSUs for a given performance period, typically during the first quarter of that fiscal year, we consider that portion of a PRSU award to be granted. Thus, each award consists of a grant in the year of award and grants in the two following years. Settlements, in our common shares, will range from zero to two times the number of PRSUs granted, depending on our financial performance relative to the targets.

We did not issue any shares of common stock to settle PRSUs vested during the three months ended June 30, 2022; however, we issued 240,412 shares of common stock to settle PRSUs vested during the nine months ended June 30, 2022. Additionally, we issued 3,716 and 238,811 shares of common stock to settle restricted stock units vested during the three and nine months ended June 30, 2022, respectively. Finally, we issued no shares of common stock to settle stock options exercised during the three months ended June 30, 2022; however, we issued 24,153 shares of common stock to settle stock options exercised during the nine months ended June 30, 2022.

Operating income included stock-based compensation expense of $2.5 million and $3.4 million for the three months ended June 30, 2022 and 2021, respectively. Operating income included stock-based compensation expense of $7.6 million and $8.4 million during the nine months ended June 30, 2022 and 2021, respectively. At June 30, 2022, there was approximately $10.5 million of unrecognized compensation expense related to stock-based compensation arrangements and there were 53,067 PRSUs that have been awarded for the 2022 performance period for which performance goal achievement cannot yet be determined.

We excluded 892,662 and 131,178 stock-based compensation instruments from the calculations of diluted earnings per share in the three months ended June 30, 2022 and 2021, respectively, and 750,343 and 566,666 for the nine months ended June 30, 2022 and 2021, respectively, since their inclusion would have been antidilutive.

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 1st 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.

Commitments and Contingencies Disclosure [Abstract]

Commitments And Contingencies

Commitments and Contingencies

We are involved in various legal proceedings that have arisen in the normal course of operations, including the proceedings summarized below. We provide for costs relating to these matters when a loss is probable and the amount is reasonably estimable. Legal costs related to these matters are expensed as incurred. 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. Other than the litigation described below, we do not believe that any of our outstanding litigation would have a materially adverse effect on our financial position, results of operations, cash flows or liquidity.

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.

In the acquisition agreement pursuant to which a predecessor to Tyco International plc, now Johnson Controls International plc (“Tyco”), sold our businesses to a previous owner in August 1999, Tyco agreed to indemnify us and our affiliates, among other things, for 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 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 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 the Environmental Protection Agency’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. Since the amounts of such costs cannot be reasonably estimated at this time, no amounts have been accrued for this matter at June 30, 2022.

The COVID-19 Pandemic. The pandemic has caused, and is likely to continue to cause, severe economic, market and other disruptions to the U.S. and global economies. We have taken action and continue to counter such disruption, and work to protect the safety of our employees. While the extent to which the pandemic affects our results will depend on future developments, the pandemic 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 claims arising from the event have been filed 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 outcome of these claims, or legal proceedings, and 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.

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 accruals as necessary. Critical factors in our 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. During the three months ended June 30, 2022, we recorded $4.5 million of warranty obligations.

We are party to a number of 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 materially adverse effect on our financial position, results of operations, cash flows or liquidity.

Acquisitions

Acquisition of i2O Water Ltd

On June 14, 2021, we acquired all the outstanding capital stock of i2O for $19.7 million, net of cash acquired. The purchase agreement provided for customary final adjustments, including a net working capital adjustment that was completed during the three months ended December 31, 2021, resulting in a purchase price of $19.5 million.

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 final. The results of i2O are included in our Water Management Solutions 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. 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.

The following is a summary of the fair values of the net assets acquired (in millions):

Assets, net of cash:
Receivables	$	0.5
Inventories	0.6
Other current assets	0.9

Revenue from External Customer [Line Items]

Revenue from Contract with Customer [Text Block]

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

We disaggregate our revenue from contracts with customers by reportable segment (see Note 10.) and further by geographical region as we believe this 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 (i.e., 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 we expect to receive within one year and therefore is included within Other current liabilities in the accompanying consolidated balance sheets. Deferred revenue represents contract liabilities and are recorded when customers remit cash payments in advance of our satisfaction of performance obligations under contractual arrangements. Contract liabilities are relieved and revenue is recognized when the performance obligation is satisfied.

The table below represents the balances of our customer receivables and deferred revenue.

	June 30,		September 30,
	2022		2021
	(in millions)
Billed receivables	$	224.3	$	213.4

Allowance for credit losses	(4.8)		(3.5)
Receivables, net	$	221.9	$	212.2
Deferred revenue	$	8.2	$	5.4

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 for sales of product or over time for 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 based typically on historical experience and known trends. We do not recognize variable consideration in the event there are uncertainties in the amount of variable consideration to be paid nor when it is probable there will be a significant reversal in the related revenue.

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 sales.

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.

The revenue recognized at a point in time related to the sale of our products is 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.

We offer warranties that 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.
