NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
AS OF AND FOR THE THREE MONTHS ENDED DECEMBER 31, 20222023
(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. 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, and pressure management and control products and software products.solutions. The “Company,” “we,” “us” or “our” refer to Mueller Water Products, Inc. and its subsidiaries. With regard to the Company’s segments, “we,” “us” or “our” may also refer to the segment being discussed.
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. During the three months ended December 31, 2021, we recorded a purchase price adjustment of $0.2 million, resulting in a final purchase price of $19.5 million.
Our condensed 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 recordingthat affect the reported amounts of assets, liabilities, sales and expenses as well as in the disclosure of contingent assets and liabilities.liabilities for the reporting periods. Actual results could differ from those estimates. All significant intercompany balances and transactions have been eliminated. These condensed consolidated financial statements do not include all information required by GAAP for complete financial statements and 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, 2022.2023. 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, 20222023 was derived from our audited financial statements, but it does not include all disclosures required by GAAP.statements.
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 monththree-month periods ending December 31 and March 31 when the northern United States and allmost of Canada generally face weather conditions that restrict significant construction activity. Therefore, the results of operations for the three months ending December 31, 2023 are not necessarily indicative of operating results that may be achieved for any other interim period or the full year.

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 Pronouncements Not Yet Adopted
In December 2022,November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2022-06, “Reference Rate Reform2023-07 “Segment Reporting (Topic 848)280): Deferral of the Sunset Date of Topic 848”Improvements to Reportable Segment Disclosures” (“ASU 2022-06”2023-07”). ASU 2022-06 defers2023-07 requires public business entities that disclose information on their reportable segments to provide additional information on their significant expense categories and “other segment items,” which represent the sunset datedifference between segment revenue less significant segment expense and a segment’s measure of profit or loss. A description of “other segment items” is also required. Further, certain segment related disclosures that were limited to annual disclosure are now required for applyinginterim periods. Finally, public business entities are required to disclose the reference rate reform relief in ASC 848title and position of their Chief Operating Decision Maker (“CODM”) and explain how the CODM uses the reported measures of profit or loss to December 31, 2024 from December 31, 2022. ASU 2022-06 became effective immediately upon issuance. 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”).assess segment performance. 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.

In December 2019, the FASB issued 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, including2023, and interim periods within that fiscal years beginning after December 15, 2024. Upon adoption, ASU 2023-07 should be applied retrospectively to all prior periods. We do not expect ASU 2023-07 to have a material impact on our financial statements and related disclosures.
In December 2023, the FASB issued ASU No 2023-09 “Income Taxes (Topic 740): Improvements to Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 requires public business entities to disclose a tabular rate reconciliation utilizing percentages and reporting currency amounts in specific categories with certain reconciling items at or above the specified 5% threshold to improve the transparency and comparability of disclosures. Additionally, entities are required to disclose the year to date amount of income taxes paid, net of refunds received, disaggregated by federal (national), state, and foreign jurisdictions. Disclosure of all individual jurisdictions where income taxes paid, net of refunds received, is 5% or more of the total is also required. This guidance is effective for fiscal years beginning after December 15, 2024 with early adoption permitted. Upon adoption, ASU 2023-09 should be applied on a prospective basis while retrospective application is permitted. We adopted this standard on October 1, 2021 and there was nodo not expect ASU 2023-09 to have a material impact toon our financial statements.

Between November 2019Strategic Reorganization and March 2021,Other Charges

During the three months ended December 31, 2023, we recorded approximately $6.6 million in Strategic reorganization and other charges, primarily consisting of $1.5 million of expenses related to the cybersecurity incidents, expenses associated with our previously 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 completed the closure of our facility in Aurora, Illinois during our fiscal year 2022. The majority of the activities from these plants were transferred to our Kimball, Tennessee facility. In connection with these reorganizations, we recognized certain restructuring costs.leadership transition as well as other transaction-related expenses. During the three months ended December 31, 2022, we recorded a $4.0 million gain, before tax, on the sale of the Aurora, Illinois facility. The restructuring accrual amountsfacility which was partially offset by transaction-related costs. Activity in accrued strategic reorganization and other charges, reported as part of December 31, 2022 and December 31, 2021 were immaterial.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. TheThe Sub-CDE then loaned $16.2 million to us, with the use of the loan proceeds restricted to foundry project expenditures. This transaction also includes a put/call provision under which we may be obligated or entitled to repurchase Wells Fargo’s interest in the investment fund. We believe that Wells Fargo will exercise its put option in December 2027 for nominal consideration, resulting in our becoming the sole owner of the investment fund, cancelling the related loans, and recognizing an estimated gain of $3.9 million.

We determined that the investment fund and the Sub-CDE are variable interest entities (“VIEs”) and that we are the primary beneficiary of the VIEs. The ongoing activities of the VIEs, namely collecting and remitting interest and fees and administering NMTC compliance, were contemplated in the initial design of the transaction and are not expected to significantly affect economic performance throughout the life of the VIEs. Additionally, we are obligated to deliver tax benefits and provide various other guarantees to Wells Fargo and to absorb the losses of the VIEs. Wells Fargo does not have a material interest in the 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 arewere expensed as incurred.incurred and were immaterial to the financial statements.

Note 2.    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

10

Table of Contents
Refer to Note 8. for disaggregation of our revenues from contracts with customers by reportable segment and by geographical region, which we believe best depicts how the nature, amount, timing and uncertaintycertainty 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 is classified as current based on the timing of when we expect to recognize revenue. We include current deferred revenue within Other current liabilities in the accompanying condensed consolidated balance sheets. Deferred revenue represents contract liabilities and is recorded when customers remit cash payments in advance of our satisfaction of performance obligations underpursuant to contractual arrangements. Contract liabilities are reversed when the performance obligation is satisfied and revenue is recognized.

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

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 equipment and products 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. The transaction price is adjusted for our estimate of variable consideration which may include discounts and rebates. To estimate variable consideration, we apply the expected value or the most likely amount method, based on whichever method most appropriately predicts the amount of consideration we expect to receive. The method applied is typically based on historical experience and known trends. We constrain the amounts of variable consideration that are included in the transaction price, to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur or when uncertainties around the variable consideration are resolved.

We exclude from the measurement of the transaction price all taxes assessed by a governmental authority.

We have elected to use the practical expedient todo 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.

Revenue for the sale of our products is recognized when the obligations of the terms of our contract are satisfied, which is when the customer is able to direct the use of and obtain substantially all of the benefits from the product, which generally occurs upon shipment when control of the product transfers to the customer.

We offer warranties to our customers in the form of assurance-type warranties, which provide assurance that the products provided will function as intended and comply with any agreed-upon specifications. These warranties cannot be purchased separately from us.

Costs to Obtain or Fulfill a Contract
Shipping and handling costs associated with freight activities after the customer has obtained control of a product are included in costaccounted for as fulfillment costs and are expensed to Cost of sales within our condensed consolidated statement of operations at the time the related revenue is recognized.

We incur certain incremental costs to obtain a contract, which primarily relate to incremental sales commissions. Our sales 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, cancellations 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 athe practical expedient to expense them as incurred and therefore do not capitalize the related costs and expense them as incurred.

ABL Agreement. Our asset-based lending agreement, as amended, (“ABL”) is provided by a consortiumsyndicate of banking institutions and consists of a revolving credit facility for up to $175.0 million in borrowingborrowings that expires on July 29, 2025. The ABL allows up to $25.0 million of swing line loans and up to $60.0 million of letters of credit. The ABL 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.

TableIn December 2023, we obtained a waiver under our ABL (“ABL Waiver”) to provide for additional time associated with certain technical reporting requirements that were delayed as a result of Contents
the cybersecurity incident announced on October 28, 2023. Under the ABL Waiver, the maximum aggregate amount of borrowings and other credit extensions under the ABL was limited to $50.0 million at any time outstanding until all of the required reports were delivered. During our first fiscal quarter of 2024, we delivered the required reports and on February 6, 2024, the ABL Waiver was terminated. Accordingly, we are no longer subject to any additional restrictions or borrowing limitations under the ABL including the $50.0 million temporary limit on credit extensions.

Borrowings under the ABL bear interest at a floating rate equal to LIBORthe Secured Overnight Financing Rate (“SOFR”) plus an adjustment of 10 basis points plus an applicable margin range of 200 to 225 basis points, or a base rate, as defined in the ABL, plus an applicable margin range of from 100 to 125 basis points. At December 31, 20222023 the applicable margin for LIBOR basedSOFR-based loans waswas 200 basis points and for base rate loans was 100 basis points.

The ABL is subject to mandatory prepayments if total outstanding borrowings under the ABL 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 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 and are jointly and severally liable for outstanding borrowings. Our obligations under the ABL are secured by a first-priority perfected lien on all of our United States inventory, accounts receivable, certain cash balances and other supporting assets.

The ABL includes a commitment fee for any unused borrowing capacity of 37.5 basis points per annum. Borrowings are not subject to any financial maintenance covenants unless excess availability is less than the greater of $17.5 million and 10% of the Loan Cap as defined in the ABL. Excess availability based on December 31, 20222023 data was $162.4 million, as reduced by $12.4 million of outstanding letters of credit and $0.2 million of accrued fees and expenses. However, during the waiver period, credit extensions were temporarily limited to $50.0 million as set forth in the waiver.

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 our previously existing 5.5% Senior Notes. Substantially all of our United States subsidiaries guarantee the 4.0% Senior Notes, which are subordinate to borrowings under our ABL. Based on quoted market prices, which is a Level 1 measurement, the outstanding 4.0% Senior Notes had a fair value of $395.8$413.0 million at December 31, 2022.2023.

An indenture securinggoverning 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 December 31, 2022.2023.

As set forth in the Indenture, weWe 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.prices as set forth in the Indenture. Upon a change of control, as defined in the Indenture, 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 5. Retirement PlansPlan

We have a defined benefit plan (“Pension Plan”) that we fund in accordance with its requirements in amounts sufficient to satisfy the minimum funding requirements of applicable laws.

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. For these awards, compensation expense is recognized even if the awards are not earned or vested. The assumptions used to determine the grant date fair value are indicated below.below for awards granted to date during the current fiscal year.

Variables used in determining grant date fair value:
Dividend yield2.20 %2.00%
Risk-free rate4.20 %4.50%
Expected term (in years)2.82.84

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 December 31, 2022,2023, the outstanding Phantom Plan instruments had a fair valuevalue of $10.76 per$14.40 per instrument and our liability for Phantom Plan instruments was $1.4$2.0 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.below for awards granted to date during the current fiscal year.

A PRSU award consists of a target number of units that may be paid out at the end of a three-year award cycle. 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.

Restricted stock units generally vest ratably over the life of the award, usually three years, on each anniversary date of the original grant. Compensation expense for restricted stock units is recognized between the grant date and the vesting date (or the date on which a participant becomes Retirement-eligible, if sooner) on a straight line basis for each tranche of each award. Fair values of restricted stock units are determined using the closing price of our common stock on the respective grant date.

Employee stock purchase plan instruments are shares of our common stock purchased by employees under the Mueller Water Products Inc. 2006 Employee Stock Purchase Plan (“ESPP”). Generally, all full-time, active employees are eligible to participate in the ESPP, subject to certain restrictions. Employee purchases are funded through payroll deductions, and excess payroll withholdings are returned to the employee. The price for the shares purchased under the ESPP is 85% of the lower of the closing price on the first day or the last day of the offering period.

We issued 282,472168,897 shares of common stock to settle PRSUs vested during the three months ended December 31, 2022. 2023.

Note 10. 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 and administrative 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 a lawsuit 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. On November 15, 2022, Mueller Canada Ltd. agreed to pay Rohcan Investments Limited C$1.5 million in settlement of all liability, damages and other claims related to the lawsuit. We have paid the settlement amount, and are pursuing indemnification from a former owner for certain potential liabilities that are alleged in this lawsuit.

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 December 31, 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 continues to affect 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. 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.

IndemnificationIndemnifications. 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, weWe 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 offer warranties on many of our products, including products related to our metrology business line, which carry an extended warranty in many instances. Our products are often utilized in harsh environmental conditions and are exposed to water and other exogenous factors such as flooding and other environmental conditions that are beyond our control. We periodically monitor and analyze our warranty experience and costs periodically andcosts. Accordingly, should specific events or issues occur, additional warranty accruals may revise our accruals as necessary. Critical factorsalso be made relating to those issues or events. Factors considered 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.

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.

Overview
Business
Approximately 60% to 65% of our 2022 net sales were associated with repair and replacement directly related to municipal water infrastructure spending, approximately 25% to 30% 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 2023 to be very challenging as a result of the ongoing inflationary pressures, labor challenges and potential recession. 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 was at healthy levels during the fiscal year 2022, especially for lot and land development activity, we anticipate that activity levels will slow in 2023 based on higher interest rates leading to a decrease in demand for new residential housing. In January 2023, Blue Chip Economic Indicators forecasted a 17.3% decrease in housing starts for the calendar year 2023 as compared to the calendar year 2022.
We have continued to incur additional costs to address the pandemic as discussed herein, including costs associated with unfavorable manufacturing variances, and labor shortages at our facilities. We expect to continue to incur such costs that may be significant as we continue to respond to the pandemic. In addition to the pandemic, the war in Ukraine has caused supply chain disruptions that have resulted in higher costs to manufacture our products and in our capital expenditures. We expect these conditions to persist in the near term.

We have two reportable segments: 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 57%50% of our fiscal 20222023 net sales. Water Management Solutions’ product and service portfolio includes fire hydrants, repair and installation, natural gas, metering, leak detection, and pressure management and control products and software products.solutions.

In October 2023, the Israel-Hamas war caused a temporary shutdown of our facility in Ariel, Israel. While we have reopened the facility, the war increases the likelihood of supply interruptions and may hinder our ability to acquire the necessary materials we need to make our products. Supply disruptions from lack of access to materials have impacted, and continue to

impact, our ability to produce and deliver our products from our facility in Ariel, Israel. Additionally, production has been impacted by labor availability.

As announced on October 28, 2023, we identified a cybersecurity incident impacting certain internal operations and information technology systems. Based on the information reviewed to date, we believe the unauthorized activity has been contained. All of our facilities are operational and have returned to normalized operations.

The cybersecurity incident consisted of unauthorized access and deployment of ransomware by a third party to a portion of our internal information infrastructure. The incident caused temporary disruptions and limitations of access to portions of our business applications supporting aspects of our operations including shipping, receiving and payment functions. Operational delays and investigation and remediation costs in connection with the incident adversely impacted our results for the first quarter of 2024. We have restored the impacted applications and systems. As reported on November 29, 2023, we identified a separate cybersecurity incident, which primarily related to a system that was at the end of its useful life and was already in the process of being replaced in the ordinary course of business.
In the first quarter of fiscal 2024, we incurred approximately $1.5 million of expenses related to the cybersecurity incidents. We continue to analyze and remediate the impacts of the cybersecurity incidents, including making enhancements to our cybersecurity processes and analyzing the data accessed, exfiltrated or otherwise impacted in connection with the cybersecurity incidents.
Although we believe that our channel and customer inventory levels normalized during the first quarter of 2024, the external operating environment remains uncertain. We expect to continue to face challenges emanating from the higher interest rate environment, the Israel-Hamas war, and labor inflation and availability. From a comparable perspective, in fiscal 2023, we benefited from fulfilling an elevated backlog for certain products, which has now become more normalized at lower levels with respect to many of our product lines as we have reduced short-cycle backlog across our portfolio, particularly with regard to iron gate valves and hydrant products. For our fiscal year 2024, we anticipate that consolidated net sales will decrease between 2 and 6 percent as compared with our fiscal year 2023. We anticipate stable demand in the municipal repair and replacement end market despite budgetary pressures on municipalities driven by the aging water infrastructure. Additionally, we anticipate that new residential construction activity will stabilize relative to the challenges in the preceding year where total housing starts decreased 12.9% in fiscal 2023 compared with the prior year according to Census data. In January 2024, Blue Chip Economic Indicators forecasted a 1.5% increase in housing starts for the calendar year 2024 as compared to the calendar year 2023. Finally, we anticipate that high interest rates will continue to impact new lot and land development, depending on the geography.

For the remainder of fiscal 2024, we anticipate that inflation will continue leading to a modest increase in manufacturing costs. We expect external challenges to persist during the balance of our fiscal year 2024. We will continue to monitor the market and economic conditions impacting our business and to take appropriate actions related thereto.

Inventory purchases increased during the three months ended December 31, 2022 asThe increase in net operating cash flow was primarily driven by improvements in working capital compared with the three months ended December 31, 2021prior year period. These included a smaller increase in Inventories, higher Receivables collections, and lower Accounts payable turnover partially as a result of supply chain management and inflation. Additionally,payment delays associated with the decline in cash as a result of operating activities during the comparable periods included: a deferred tax increase of $4.5 million, a pension expense increase of $1.8 million, and a $1.2 million increase in inventory reserves. Other current liabilities and other noncurrent liabilities decreased primarily as a result of the timing of payroll payments, the repayment of the CARES Act employer payroll tax deferral, interest payments, and the payment of restructuring expenses.

Capital expenditures were $9.9$5.7 million in the three months ended December 31, 20222023 as compared with $11.0$9.9 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 2023,2024, we have provided guidance that our capital expenditures are expected to be between $70.0$45.0 million and $80.0$50.0 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,needs, income tax payments, capital expenditures and debt service obligations as they become due through December 31, 2023.the twelve months from the date of this filing. However, our ability to make these payments will depend largely on our future operating performance, which may be affected by general economic, financial, competitive, legislative, regulatory, business and other factors beyond our control.

ABL Agreement
As of December 31, 2022, ourOur ABL is provided by a consortiumsyndicate of banking institutions and consists of a revolving credit facility for up toof $175.0 million in borrowingsborrowing capacity that expires on July 28,29, 2025. Included in the ABL is the ability to borrow up to $25.0 million of swing line loans and up to $60.0 million of letters of credit. The ABL 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.

In December 2023, we obtained a waiver under our ABL (“ABL Waiver”) to provide for additional time associated with certain technical reporting requirements that were delayed as a result of the cybersecurity incident announced on October 28, 2023. Under the ABL Waiver, the maximum aggregate amount of borrowings and other credit extensions under the ABL was limited to $50.0 million at any time outstanding until all of the required reports were delivered. During our first fiscal quarter of 2024, we delivered the required reports and on February 6, 2024, the ABL Waiver was terminated. Accordingly, we are no longer subject to any additional restrictions or borrowing limitations under the ABL, including the $50.0 million temporary limit on credit extensions.

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. Based on quoted market prices, which is a Level 1 measurement, the outstanding 4.0% Senior Notes had a fair value of $395.8$413.0 million at December 31, 2022.2023.

There are no financial maintenance covenants associated with the Indenture.

Material Cash Requirements

We enter into a variety of contractual obligations as part of our normal operations in addition to capital expenditures. As of December 31, 2022,2023, we have (i) debt obligations related to our $450.0 million 4.0% Senior Notes which mature in 2029 and include annual cash interest payments of $18.0$18.0 million in 2023 annually2024 through 2029, (ii) cumulative cash obligationsobligations of $31.4$37.4 million for operating leases through 2033 and $1.4$1.1 million for finance leases through 2026,2028, and (iii) purchase obligations for raw materials and other parts of approximately $154.0approximately $107.4 million which we expect to incur during the next 12 months.months and $2.0 million beyond December 31, 2024. Additionally, we may continue to strengthen our systems, cybersecurity training, policies, programs, response plans and other similar measures as a result of the cybersecurity incidents. 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 December 31, 20222023 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 December 31, 2022,2023, we had $12.4$12.4 million of letters of credit and $32.5$13.7 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 allmost of Canada generally face weather conditions that restrict significant construction activity.

Critical Accounting Estimates

The preparation of financial statements in accordance with accounting GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. These estimates are based upon experience and on various other assumptions we believe to be reasonable under the circumstances. Actual results may differ from these estimates. We consider an accounting estimate to be critical if changes in the estimate that are reasonably likely to occur over time or the use of reasonably different estimates could have a material impact on our financial condition or results of operations. Our critical accounting estimates can be found in the “Critical Accounting Estimates” section in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the Company’s 20222023 Annual Report on Form 10-K. There have been no changes in the Company’s determination of critical accounting policies and estimates since September 30, 2022.2023.

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 December 31, 2022.2023.

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.

29

Our management, including our Chief Executive Officer and our 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.
