NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

General

Certain information and note disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) have been condensed or omitted. Results of operations for the interim periods presented are not necessarily indicative of results which may be expected for any other interim period or for the year as a whole. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K, including the annual financial statements incorporated therein.

The accompanying unaudited interim financial statements include all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented herein. Certain prior year balances have been reclassified to conform to current year presentation.

Note 1 – Recent Accounting Standards

Adopted

In June 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. The new guidance was issued to clarify existing guidance measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security and introduce new disclosure requirements for applicable equity securities. The ASU was effective for fiscal years beginning after December 15, 2023 for public entities. The guidance requires prospective adoption, and early adoption was permitted. The Company adopted the ASU during the first quarter of 2024. The adoption of the ASU did not have a material impact on the Company’s Condensed Consolidated Financial Statements.

Issued

In March 2024, the Securities and Exchange Commission issued final rules on the enhancement and standardization of climate-related disclosures. The rules require disclosure of, among other things: material climate-related risks, activities to mitigate or adapt to such risks, governance and management of such risks, and material greenhouse gas (GHG) emissions from operations owned or controlled (Scope 1) and/or indirect emissions from purchased energy consumed in operations (Scope 2). Additionally, the rules require disclosure in the notes to the financial statements of the effects of severe weather events and other natural conditions, subject to certain materiality thresholds. The rules will become effective on a phased-in timeline in fiscal years beginning in 2025. The Company is in the process of analyzing the impact of the rules on its disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The new guidance primarily enhances and expands both the income tax rate reconciliation disclosure and the income taxes paid disclosure. The ASU is effective for annual periods beginning after December 15, 2024 for public entities on a prospective basis. Early adoption is permitted. The Company is in the process of analyzing the impact of the standard on its disclosures.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The new guidance requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. The ASU applies to all public entities and is effective for fiscal years beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. The guidance requires retrospective adoption, and early adoption is permitted. The Company is in the process of analyzing the impact of the standard on its disclosures.

Note 2 – Earnings per Common Share

Basic per share amounts have been computed based on the average number of common shares outstanding. Diluted per share amounts reflect the increase in average common shares outstanding that would result from the assumed exercise of outstanding stock options and vesting of restricted and performance stock awards, computed using the treasury stock method.

On September 26, 2023, the Company’s shareholders approved an amendment to the Company’s Restated Certificate of Incorporation to increase the total number of authorized shares of Common Stock from 100,000,000 to 250,000,000. Subsequently, the Company’s Board of Directors announced a two-for-one stock split of its common stock effected in the form of a stock dividend of one share for each outstanding share. The record date for the stock split was October 6, 2023, and the additional shares were distributed on October 20, 2023. All references to share and per share amounts presented in the Condensed Consolidated Financial Statements and this Quarterly Report on Form 10-Q have been adjusted retroactively to reflect the stock split.

Note 3 – Disposition

Heatlink Group

On September 2, 2021, the Company entered into a contribution agreement with a limited liability company in the retail distribution business, pursuant to which the Company exchanged the outstanding common stock of Die-Mold for a 17 percent equity interest in the limited liability company. Die-Mold manufactures PEX and other plumbing-related fittings and plastic injection tooling in Canada and sells these products in Canada and the U.S. and was included in the Piping Systems segment.

Effective July 3, 2023, the Company transferred 100 percent of the outstanding shares of Heatlink Group, Inc. and Heatlink Group USA, LLC for an additional 11 percent equity interest in the limited liability company. Heatlink Group produces a complete line of products for PEX plumbing and radiant systems in Canada and sells these products in Canada and the U.S. and was included in the Piping Systems segment. Heatlink Group reported net sales of $7.7 million and operating income of $0.9 million in the first quarter of 2023. As a result of the transaction, the Company recognized a gain of $4.1 million in the third quarter of 2023 based on the excess of the fair value of the consideration received (the 11 percent equity interest) over the carrying value of Heatlink Group. The Company equally weighted an income discounted cash flow approach and market comparable companies approach using an EBITDA multiple to determine the fair value of the consideration received of $26.0 million, which is recognized within the Investments in unconsolidated affiliates line of the Condensed Consolidated Balance Sheet. The excess of the fair value of the deconsolidated subsidiary over its carrying value resulted in the gain.

Note 4 – Segment Information

Note 7 – Financial Instruments

Short-Term Investments

The fair value of short-term investments at December 30, 2023, consisting of marketable securities, approximates the carrying value on that date. These marketable securities are stated at fair value and classified as level 1 within the fair value hierarchy. This classification is defined as a fair value determined using observable inputs that reflect quoted prices in active markets for identical assets.

Derivative Instruments and Hedging Activities

The Company’s earnings and cash flows are subject to fluctuations due to changes in commodity prices, foreign currency exchange rates, and interest rates. The Company uses derivative instruments such as commodity futures contracts, foreign currency forward contracts, and interest rate swaps to manage these exposures.

All derivatives are recognized in the Condensed Consolidated Balance Sheets at their fair values. On the date the derivative contract is entered into, it is either a) designated as a hedge of a forecasted transaction or the variability of cash flow to be paid (cash flow hedge) or b) not designated in a hedge accounting relationship, even though the derivative contract was executed to mitigate an economic exposure (economic hedge), as the Company does not enter into derivative contracts for trading purposes. Changes in the fair value of a derivative that is qualified, designated, and highly effective as a cash flow hedge are recorded in stockholders’ equity within AOCI, to the extent effective, until they are reclassified to earnings in the same period or periods during which the hedged transaction affects earnings. Changes in the fair value of undesignated derivatives executed as economic hedges are reported in current earnings.

The Company documents all relationships between derivative instruments and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivative instruments that are designated as fair value hedges to specific assets and liabilities in the Condensed Consolidated Balance Sheets and linking cash flow hedges to specific forecasted transactions or variability of cash flow.

The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the designated derivative instruments that are used in hedging transactions are highly effective in offsetting changes in cash flows or fair values of hedged items. When a derivative instrument is determined not to be highly effective as a hedge or the underlying hedged transaction is no longer probable of occurring, hedge accounting is discontinued prospectively in accordance with the derecognition criteria for hedge accounting.

Commodity Futures Contracts

Copper and brass represent the largest component of the Company’s variable costs of production. The cost of these materials is subject to global market fluctuations caused by factors beyond the Company’s control. The Company occasionally enters into forward fixed-price arrangements with certain customers; the risk of these arrangements is generally managed with commodity futures contracts. These futures contracts have been designated as cash flow hedges.

At March 30, 2024, the Company held open futures contracts to purchase approximately $16.9 million of copper over the next 12 months related to fixed price sales orders. The fair value of those futures contracts was a $492 thousand net gain position, which was determined by obtaining quoted market prices (level 1 within the fair value hierarchy). In the next 12 months, the Company will reclassify into earnings realized gains or losses relating to cash flow hedges. At March 30, 2024, this amount was approximately $384 thousand of deferred net gains, net of tax.

The Company may also enter into futures contracts to protect the value of inventory against market fluctuations. At March 30, 2024, the Company held $106.3 million open futures contracts to sell copper over the next six months related to copper inventory. The fair value of those futures contracts was a $2.3 million net loss position, which was determined by obtaining quoted market prices (level 1 within the fair value hierarchy).

The Company presents its derivative assets and liabilities in the Condensed Consolidated Balance Sheets on a net basis by counterparty. The following table summarizes the location and fair value of the derivative instruments and disaggregates the net derivative assets and liabilities into gross components on a contract-by-contract basis:


	Asset Derivatives					Liability Derivatives

The Company primarily enters into International Swaps and Derivatives Association master netting agreements with major financial institutions that permit the net settlement of amounts owed under their respective derivative contracts. Under these master netting agreements, net settlement generally permits the Company or the counterparty to determine the net amount payable for contracts due on the same date and in the same currency for similar types of derivative transactions. The master netting agreements generally also provide for net settlement of all outstanding contracts with a counterparty in the case of an event of default or a termination event. The Company does not offset fair value amounts for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral. At March 30, 2024 and December 30, 2023, the Company had recorded restricted cash in other current assets of $6.6 million and $3.2 million, respectively, as collateral related to open derivative contracts under the master netting arrangements.

Long-Term Debt

The fair value of long-term debt at March 30, 2024 approximates the carrying value on that date. The estimated fair values were determined based on quoted market prices and the current rates offered for debt with similar terms and maturities. The fair value of long-term debt is classified as level 2 within the fair value hierarchy. This classification is defined as a fair value determined using market-based inputs other than quoted prices that are observable for the liability, either directly or indirectly.

Note 8 – Investments in Unconsolidated Affiliates

Tecumseh

The Company owns a 50 percent interest in an unconsolidated affiliate that acquired Tecumseh Products Company LLC (Tecumseh) and an entity that provides financing to Tecumseh. This investment is recorded using the equity method of accounting, as the Company can exercise significant influence but does not own a majority equity interest or otherwise control the entity. Under the equity method of accounting, this investment is stated at initial cost and is adjusted for subsequent additional investments and the Company’s proportionate share of earnings or losses and distributions.

The Company records its proportionate share of the investee’s net income or loss, net of foreign taxes, one quarter in arrears as income (loss) from unconsolidated affiliates, net of foreign tax, in the Condensed Consolidated Statements of Income and its proportionate share of the investee’s other comprehensive income (loss), net of income taxes, in the Condensed Consolidated Statements of Comprehensive Income and the Condensed Consolidated Statements of Changes in Equity. The U.S. tax effect of the Company’s proportionate share of Tecumseh’s income or loss is recorded in income tax expense in the Condensed Consolidated Statements of Income. In general, the equity investment in unconsolidated affiliates is equal to the current equity investment plus the investee’s net accumulated losses.

The Company’s net loss from unconsolidated affiliates, net of foreign tax, for the quarters ended March 30, 2024 and April 1, 2023 included losses of $10.3 million and $2.4 million, respectively, for Tecumseh.

During the first quarter of 2024, the Company advanced Tecumseh $12.5 million.

Retail Distribution

The Company owns a 28 percent noncontrolling equity interest in a limited liability company in the retail distribution business. This investment is recorded using the equity method of accounting. The Company records its proportionate share of the investee’s net income or loss one month in arrears as income (loss) from unconsolidated affiliates in the Condensed Consolidated Statements of Income. The Company’s proportionate share of the investee’s other comprehensive income (loss), net of income taxes, is recorded in the Condensed Consolidated Statements of Comprehensive Income and Condensed Consolidated Statement of Changes in Equity.

The Company’s net loss from unconsolidated affiliates, net of foreign tax, for the quarters ended March 30, 2024 and April 1, 2023 included income of $2.3 million and $1.4 million, respectively, for the retail distribution business.

Note 9 – Benefit Plans

The Company sponsors several qualified and nonqualified pension plans and other postretirement benefit plans for certain of its employees. The components of net periodic benefit cost (income) are as follows:


	For the Quarter Ended

The components of net periodic benefit cost (income) other than the service cost component are included in other income, net in the Condensed Consolidated Statements of Income.

Note 10 – Commitments and Contingencies

The Company is involved in certain litigation as a result of claims that arose in the ordinary course of business, which management believes will not have a material adverse effect on the Company’s financial position, results of operations, or cash flows. The Company may also realize the benefit of certain legal claims and litigation in the future; these gain contingencies are not recognized in the Condensed Consolidated Financial Statements.

Environmental

Non-operating Properties

Southeast Kansas Sites

The Kansas Department of Health and Environment (KDHE) has contacted the Company regarding environmental contamination at three former smelter sites in Kansas (Altoona, East La Harpe, and Lanyon). The Company is not a successor to the companies that operated these smelter sites, but is exploring possible settlement with KDHE and other potentially responsible parties (PRP) in order to avoid litigation.

In February 2022, the Company reached a settlement with another PRP relating to these three sites. Under the terms of that agreement, the Company paid $5.6 million, which was previously reserved, in exchange for the other PRP’s agreement to conduct or fund any required remediation within the geographic boundaries of the three sites (namely, the parcel(s) on which the former smelters were located), plus coverage of certain off-site areas (namely, contamination that migrated by surface water runoff or air emissions from the Altoona or East La Harpe site, and smelter materials located within 50 feet of the geographic boundary of each site). The settlement does not cover certain matters, including potential liability related to the remediation of the town of Iola which is not estimable at this time. The other PRP will also provide an indemnity that would cover third-party cleanup claims for those sites, subject to a time limit and a cap.

Altoona. Another PRP conducted a site investigation of the Altoona site under a consent decree with KDHE and submitted a removal site evaluation report recommending a remedy. The remedial design plan, which covers both on-site and certain off-site cleanup costs, was approved by the KDHE in 2016. Construction of the remedy was completed in 2018. Under the terms of the settlement with the other PRP, the Company expects the operations and maintenance costs for this remedy to be paid for entirely by the other PRP.

East La Harpe. At the East La Harpe site, the Company and two other PRPs conducted a site study evaluation under KDHE supervision and prepared a site cleanup plan approved by KDHE. In December 2018, KDHE provided a draft agreement which contemplates the use of funds KDHE obtained from two other parties (Peabody Energy and Blue Tee) to fund part of the remediation, and removes Blue Tee from the PRPs’ agreement with KDHE. Pursuant to the terms of the settlement with the other PRP noted above, the Company expects the remediation to be conducted and paid for entirely by the other PRP, and for the other PRP to negotiate and enter into an agreement with KDHE.

Lanyon. With respect to the Lanyon Site, in 2016, the Company received a general notice letter from the United States Environmental Protection Agency (EPA) asserting that the Company is a PRP, which the Company has denied. EPA issued an interim record of decision in 2017 and has been remediating properties at the site. Approximately 1,371 properties were to be remediated. In August 2023, EPA issued a five-year review indicating that the cleanup of approximately 300 remaining residential properties would be completed in 2026. A record of decision concerning the cleanup is scheduled for May 2025.

Shasta Area Mine Sites

Mining Remedial Recovery Company (MRRC), a wholly owned subsidiary, owns certain inactive mines in Shasta County, California. MRRC has continued a program, begun in the late 1980s, of implementing various remedial measures, including sealing mine portals with concrete plugs in portals that were discharging water. The sealing program achieved significant reductions in the metal load in discharges from these adits; however, additional reductions are required pursuant to an order issued by the California Regional Water Quality Control Board (QCB). In response to a 1996 QCB Order, MRRC completed a feasibility study in 1997 describing measures designed to mitigate the effects of acid rock drainage. In December 1998, the QCB modified the 1996 order extending MRRC’s time to comply with water quality standards. In September 2002, the QCB adopted a new order requiring MRRC to adopt Best Management Practices (BMP) to control discharges of acid mine drainage, and again extended the time to comply with water quality standards until September 2007. During that time, implementation of BMP further reduced impacts of acid rock drainage; however, full compliance has not been achieved. The QCB is presently renewing MRRC’s discharge permit and will concurrently issue a new order. It is expected that the new 10-year permit will

include an order requiring continued implementation of BMP through 2033 to address residual discharges of acid rock drainage. The Company currently estimates that it will spend between approximately $14.1 million and $16.1 million for remediation at these sites over the next 30 years and has accrued a reserve at the low end of this range.

Lead Refinery Site

U.S.S. Lead Refinery, Inc. (Lead Refinery), a non-operating wholly owned subsidiary of MRRC, has conducted corrective action and interim remedial activities (collectively, Site Activities) at Lead Refinery’s East Chicago, Indiana site pursuant to the Resource Conservation and Recovery Act since December 1996. Although the Site Activities have been substantially concluded, Lead Refinery is required to perform monitoring and maintenance-related activities pursuant to a post-closure permit issued by the Indiana Department of Environmental Management effective as of March 2, 2013. Approximate costs to comply with the post-closure permit, including associated general and administrative costs, are estimated at between $1.6 million and $2.2 million over the next 13 years. The Company has recorded a reserve at the low end of this range.

On April 9, 2009, pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the U.S. Environmental Protection Agency (EPA) added the Lead Refinery site and surrounding properties to the National Priorities List (NPL). On July 17, 2009, Lead Refinery received a written notice from the EPA indicating that it may be a PRP under CERCLA due to the release or threat of release of hazardous substances including lead into properties surrounding the Lead Refinery NPL site. The EPA identified two other PRPs in connection with that matter. In November 2012, the EPA adopted a remedy for the surrounding properties and in September 2014, the EPA announced that it had entered into a settlement with the two other PRPs whereby they will pay approximately $26.0 million to fund the cleanup of approximately 300 properties surrounding the Lead Refinery NPL site (zones 1 and 3 of operable unit 1) and perform certain remedial action tasks.

On November 8, 2016, the Company, its subsidiary Arava Natural Resources Company, Inc. (Arava), and Arava’s subsidiary MRRC each received general notice letters from the EPA asserting that they may be PRPs in connection with the Lead Refinery NPL site. The Company, Arava, and MRRC have denied liability for any remedial action and response costs associated with the Lead Refinery NPL site. In June 2017, the EPA requested that Lead Refinery conduct, and the Company fund, a remedial investigation and feasibility study of operable unit 2 of the Lead Refinery NPL site pursuant to a proposed administrative settlement agreement and order on consent. The Company and Lead Refinery entered into that agreement in September 2017. The Company has made a capital contribution to Lead Refinery to conduct the remedial investigation and feasibility study with respect to operable unit 2 and has provided financial assurance in the amount of $1.0 million. The remedial investigation and feasibility study remain ongoing. The EPA has also asserted its position that Mueller is a responsible party for the Lead Refinery NPL site, and accordingly is responsible for a share of remedial action and response costs at the site and in the adjacent residential area.

In January 2018, the EPA issued two unilateral administrative orders (UAOs) directing the Company, Lead Refinery, and four other PRPs to conduct soil and interior remediation of certain residences at the Lead Refinery NPL site (zones 2 and 3 of operable unit 1). Subsequent thereto, the Company and Lead Refinery have reached agreement with the four other PRPs to implement these two UAOs, with the Company agreeing to pay, on an interim basis, (i) an estimated $4.5 million (subject to potential change through a future reallocation process) of the approximately $25.0 million the PRPs then estimated it would cost to implement the UAOs, which estimate is subject to change, and (ii) $2.0 million relating to past costs incurred by other PRPs for work conducted at the site, as well as the possibility of up to $0.7 million in further payments for ongoing work by those PRPs. As of March 30, 2024, the Company has made payments of approximately $7.6 million related to the aforementioned agreement with the other PRPs. The Company disputes that it was properly named in the UAOs. In March 2022, Lead Refinery entered into an administrative settlement agreement and order on consent with the EPA, along with the four other PRPs, which involves payment of certain past and future costs relating to operable unit 1, in exchange for certain releases and contribution protection for the Company, Lead Refinery, and their respective affiliates relating to that operable unit. The settlement became effective in September 2022. The Company reserved $3.3 million for this settlement at the end of 2021. In March 2018, a group of private plaintiffs sued the Company, Arava, MRRC, and Lead Refinery, along with other defendants, in civil tort action relating to the site. The Company, Arava, and MRRC have been voluntarily dismissed from that litigation without prejudice. Lead Refinery subsequently answered plaintiff’s amended complaint, but has filed a motion for partial judgment on the pleadings which remains pending. At this juncture, the Company is unable to determine the likelihood of a material adverse outcome or the amount or range of a potential loss in excess of the current reserve with respect to any remedial action or litigation relating to the Lead Refinery NPL site, either at Lead Refinery’s former operating site (operable unit 2) or the adjacent residential area (operable unit 1), including, but not limited to, EPA oversight costs for which the EPA may attempt to seek reimbursement from the Company, and past costs for which other PRPs may attempt to seek contribution from the Company.

Bonita Peak Mining District

Following an August 2015 spill from the Gold King Mine into the Animas River near Silverton, Colorado, the EPA listed the Bonita Peak Mining District on the NPL. Said listing was finalized in September 2016. The Bonita Peak Mining District encompasses 48 mining sites within the Animas River watershed, including the Sunnyside Mine, the American Tunnel, and the Sunbank Group. On or about July 25, 2017, Washington Mining Company (Washington Mining) (a wholly-owned subsidiary of the Company’s wholly-owned subsidiary, Arava), received a general notice letter from the EPA stating that Washington Mining may be a PRP under CERCLA in connection with the Bonita Peak Mining District site and therefore responsible for the remediation of certain portions of the site, along with related costs incurred by the EPA. Shortly thereafter, the Company received a substantively identical letter asserting that it may be a PRP at the site and similarly responsible for the cleanup of certain portions of the site. The general notice letters identify one other PRP at the site, and do not require specific action by Washington Mining or the Company at this time. At this juncture, the Company is unable to determine the likelihood of a materially adverse outcome or the amount or range of a potential loss with respect to any remedial action related to the Bonita Peak Mining District NPL site.

Operating Properties

Mueller Copper Tube Products, Inc.

In 1999, Mueller Copper Tube Products, Inc. (MCTP), a wholly owned subsidiary, commenced a cleanup and remediation of soil and groundwater at its Wynne, Arkansas plant to remove trichloroethylene, a cleaning solvent formerly used by MCTP. On August 30, 2000, MCTP received approval of its Final Comprehensive Investigation Report and Storm Water Drainage Investigation Report addressing the treatment of soils and groundwater from the Arkansas Department of Environmental Quality (ADEQ). The Company established a reserve for this project in connection with the acquisition of MCTP in 1998. Effective November 17, 2008, MCTP entered into a Settlement Agreement and Administrative Order by Consent to submit a Supplemental Investigation Work Plan (SIWP) and subsequent Final Remediation Work Plan (RWP) for the site. By letter dated January 20, 2010, ADEQ approved the SIWP as submitted, with changes acceptable to the Company. On December 16, 2011, MCTP entered into an amended Administrative Order by Consent to prepare and implement a revised RWP regarding final remediation for the Site. The remediation system was activated in February 2014. Costs to implement the work plans, including associated general and administrative costs, are estimated to approximate $0.4 million over the next two years.

United States Department of Commerce Antidumping Review

On December 24, 2008, the Department of Commerce (DOC) initiated an antidumping administrative review of the antidumping duty order covering circular welded non-alloy steel pipe and tube from Mexico for the November 1, 2007 through October 31, 2008 period of review. The DOC selected Mueller Comercial as a respondent in the review. On April 19, 2010, the DOC published the final results of the review and assigned Mueller Comercial an antidumping duty rate of 48.33 percent. On May 25, 2010, the Company appealed the final results to the U.S. Court of International Trade (CIT). On December 16, 2011, the CIT issued a decision remanding the Department’s final results. While the matter was still pending, the Company and the United States reached an agreement to settle the appeal. Subject to the conditions of the agreement, the Company anticipated that certain of its subsidiaries would incur antidumping duties on subject imports made during the period of review and, as such, established a reserve for this matter. After the lapse of the statutory period of time during which U.S. Customs and Border Protection (CBP) was required, but failed, to liquidate the entries at the settled rate, the Company released the reserve. Between October 30, 2015 and November 27, 2015, CBP sent a series of invoices to Southland Pipe Nipples Co., Inc. (Southland), requesting payment of approximately $3.0 million in duties and interest in connection with 795 import entries made during the November 1, 2007 through October 31, 2008 period. On January 26, 2016 and January 27, 2016, Southland filed protests with CBP in connection with these invoices, noting that CBP’s asserted claims were not made in accordance with applicable law, including statutory provisions governing deemed liquidation. The Company believes in the merits of the legal objections raised in Southland’s protests, and CBP’s response to Southland’s protests is currently pending. Given the procedural posture and issues raised by this legal dispute, the Company cannot estimate the amount of potential duty liability, if any, that may result from CBP’s asserted claims.

Guarantees

Guarantees, in the form of letters of credit, are issued by the Company generally to assure the payment of insurance deductibles, certain retiree health benefits, and debt at certain unconsolidated affiliates. The terms of the guarantees are generally one year but are renewable annually as required. These letters are primarily backed by the Company’s revolving credit facility. The maximum payments that the Company could be required to make under its guarantees at March 30, 2024 were $28.9 million.

Note 11 – Income Taxes

The Company’s effective tax rate for the first quarter of 2024 was 26 percent compared with 26 percent for the same period last year. The primary items impacting the effective tax rate for the first quarter of 2024 were increases related to the provision for state income taxes, net of the federal benefit, of $5.9 million, the effect of foreign tax rates higher than statutory tax rates and other foreign adjustments of $1.5 million, and other items of $2.1 million.

The items impacting the effective tax rate for the first quarter of 2023 were increases related to the provision for state income taxes, net of the federal benefit, of $7.8 million, the effect of foreign tax rates higher than statutory tax rates and other foreign adjustments of $2.1 million, and other items of $1.6 million.

The Company files a consolidated U.S. federal income tax return and numerous consolidated and separate-company income tax returns in many state, local, and foreign jurisdictions. The statute of limitations is open for the Company’s federal tax return for 2020 and all subsequent years. The statutes of limitations for most state returns are open for 2020 and all subsequent years, and some state and foreign returns are also open for some earlier tax years due to differing statute periods. While the Company believes that it is adequately reserved for possible audit adjustments, the final resolution of these examinations cannot be determined with certainty and could result in final settlements that differ from current estimates.

The international tax framework introduced by the Organisation for Economic Co-operation and Development under its Pillar Two initiative includes a global minimum tax of 15 percent. Legislation adopting these provisions has been enacted in certain jurisdictions where the Company operates and is effective for the Company's 2024 fiscal year. The Company has assessed this legislation and the Pillar Two provisions do not have a material impact on the Company’s tax expense.

Note 12 – Accumulated Other Comprehensive Income (Loss)

AOCI includes certain foreign currency translation adjustments from those subsidiaries not using the U.S. dollar as their functional currency, net deferred gains and losses on certain derivative instruments accounted for as cash flow hedges, adjustments to pension and OPEB liabilities, and other comprehensive income attributable to unconsolidated affiliates.

Note 13 – Insurance Claim

In March 2023, a portion of the Company’s Covington, Tennessee manufacturing operation was damaged by a tornado. The extent of the damage to inventories, production equipment, and building structures is currently being assessed. The total value of the loss, including business interruption, cannot be determined at this time, but is expected to be covered by property and business interruption insurance subject to customary deductibles. Any gain resulting from insurance proceeds for property damage in excess of the net book value of the related property will be recognized in income upon settlement of the claim. In addition, the Company has deferred recognition of direct, identifiable costs associated with this matter. These costs will also be recognized upon settlement of the insurance claim. As of March 30, 2024, the Company has received advances totaling $25.0 million from the insurance company for this claim, of which $15.0 million was received during 2024. These advances, net of the book value of damaged inventories, equipment, and buildings and direct cleanup and other out of pocket costs totaled $14.0 million, classified as other current liabilities on the Condensed Consolidated Balance Sheet at March 30, 2024.

Note 14 - Subsequent Event

On April 19, 2024, the Company entered into a definitive agreement to acquire Nehring Electrical Works Company and certain of its affiliated companies (collectively, “Nehring”) for approximately $575.0 million, subject to customary purchase price adjustments, plus an additional $25.0 million earn out. Nehring produces high-quality wire and cable solutions for the utility,

telecommunication, electrical distribution, and OEM markets. The acquisition, which will be funded with cash on hand, is expected to close during the second quarter of 2024, subject to regulatory approval and customary closing conditions. For the twelve months ended December 31, 2023, Nehring’s annual net sales were approximately $400.0 million.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

General Overview

We are a leading manufacturer of copper, brass, aluminum, and plastic products. The range of products we manufacture is broad: copper tube and fittings; line sets; brass rod, bar, and shapes; aluminum and brass forgings; aluminum impact extrusions; refrigeration valves and fittings; compressed gas valves; pressure vessels; steel nipples; and insulated flexible duct systems. We also resell brass and plastic plumbing valves, plastic fittings, malleable iron fittings, faucets, and plumbing specialty products. Our operations are located throughout the United States and in Canada, Mexico, Great Britain, South Korea, the Middle East, and China.

Each of our reportable segments is composed of certain operating segments that are aggregated primarily by the nature of products offered as follows:

•Piping Systems: The Piping Systems segment is composed of Domestic Piping Systems Group, Great Lakes Copper, European Operations, Trading Group, Jungwoo-Mueller (our South Korean joint venture), and Mueller Middle East (our Bahraini joint venture). The Domestic Piping Systems Group manufactures and distributes copper tube, fittings, and line sets. These products are manufactured in the U.S., sold in the U.S., and exported to markets worldwide. Great Lakes Copper manufactures copper tube and line sets in Canada and sells the products primarily in the U.S. and Canada. European Operations manufactures copper tube in the United Kingdom, which is sold throughout Europe. The Trading Group manufactures pipe nipples and sources products for import distribution in North America. Jungwoo-Mueller manufactures copper-based joining products that are sold worldwide. Mueller Middle East manufactures copper tube and serves markets in the Middle East and Northern Africa. The Piping Systems segment sells products to wholesalers in the plumbing and refrigeration markets, distributors to the manufactured housing and recreational vehicle industries, building material retailers, and air-conditioning original equipment manufacturers (OEMs).

•Industrial Metals: The Industrial Metals segment is composed of Brass Rod, Impacts & Micro Gauge, Brass Value-Added Products, and Precision Tube. The segment manufactures and sells brass rod, bar, and shapes; aluminum and brass forgings; aluminum impact extrusions; gas valves and assemblies; and specialty copper, copper alloy, and aluminum tube. The segment manufactures and sells its products primarily to domestic OEMs in the industrial, transportation, construction, heating, ventilation, and air-conditioning, plumbing, refrigeration, and energy markets.

•Climate: The Climate segment is composed of Refrigeration Products, Westermeyer, Turbotec, Flex Duct, and Linesets, Inc. The segment manufactures and sells refrigeration valves and fittings, high pressure components, coaxial heat exchangers, insulated HVAC flexible duct systems, and line sets. The segment sells its products primarily to the heating, ventilation, air-conditioning, and refrigeration markets in the U.S.

New housing starts and commercial construction are important determinants of our sales to the heating, ventilation, and air-conditioning, refrigeration, and plumbing markets because the principal end use of a significant portion of our products is in the construction of single and multi-family housing and commercial buildings. Repairs and remodeling projects are also important drivers of underlying demand for these products. In addition, our products are used in various transportation, automotive, and industrial applications.

According to the U.S. Census Bureau, the March 2024 seasonally adjusted annual rate of new housing starts was 1.32 million, compared to the March 2023 rate of 1.38 million. The average 30-year fixed mortgage rate was 6.75 percent for the first quarter of 2024 and 6.81 percent for the twelve months ended December 2023. The private non-residential construction sector includes offices, industrial, health care, and retail projects. According to the U.S. Census Bureau, the seasonally adjusted annual value of private nonresidential construction put in place was $716.0 billion in February 2024 compared to the February 2023 rate of $636.0 billion.

Profitability of certain of our product lines depends upon the “spreads” between the cost of raw material and the selling prices of our products. The open market prices for copper cathode and copper and brass scrap, for example, influence the selling price of copper tube and brass rod, two principal products manufactured by the Company. We attempt to minimize the effects on

profitability from fluctuations in material costs by passing through these costs to our customers; however, margins of our businesses that account for inventory on a FIFO basis may be impacted in periods of significant fluctuations in material costs. Our earnings and cash flow are dependent upon these spreads that fluctuate based upon market conditions.

Earnings and profitability are also impacted by unit volumes that are subject to market trends, such as substitute products, imports, technologies, and market share. We intensively manage our pricing structure while attempting to maximize profitability. From time-to-time, this practice results in lost sales opportunities and lower volume. For plumbing systems, plastics are the primary substitute product; these products represent an increasing share of consumption. For certain air-conditioning and refrigeration applications, aluminum-based systems are the primary substitution threat. We cannot predict the acceptance or the rate of switching that may occur. U.S. consumption of copper tube and brass rod is still predominantly supplied by U.S. manufacturers. In recent years, brass rod consumption in the U.S. has declined due to the outsourcing of many manufactured products to offshore regions.

Results of Operations

Net selling price in core product lines	(3.8)	%
Unit sales volume in core product lines	(4.1)

Dispositions	(0.8)
Other	(3.8)

	(12.5)	%

The decrease in net sales during the first quarter of 2024 was primarily due to (i) lower unit sales volume of $39.8 million in our core product lines, primarily copper tube and line sets, (ii) a decrease in sales of $37.3 million in our non-core product lines, (iii) lower net selling prices of $36.7 million in our core product lines, and (iv) a decrease in sales of $7.7 million as a result of the disposition of Heatlink Group during the third quarter of 2023.

Net selling prices generally fluctuate with changes in raw material costs. Changes in raw material costs are generally passed through to customers by adjustments to selling prices. The following graph shows the Comex average copper price per pound by quarter for the current and prior fiscal years:

The following tables compare cost of goods sold and operating expenses as dollar amounts and as a percent of net sales for the first quarter of 2024 and 2023:

Depreciation and amortization		1.1		1.1
Selling, general, and administrative expense		5.7		5.4






Operating expenses		78.4	%	76.4	%

Cost of goods sold decreased in the first quarter of 2024 primarily due to the factors noted above regarding the change in net sales. Gross margin as a percentage of sales was 28.4 percent compared with 30.1 percent in the prior year quarter. Depreciation and amortization decreased in the first quarter of 2024 primarily as a result of several long-lived assets becoming fully depreciated and as a result of long-lived assets sold with Heatlink Group. Selling, general, and administrative expense decreased in the first quarter of 2024 primarily as a result of (i) higher foreign currency transaction gains of $1.7 million, (ii) a gain on the sale of assets of $1.6 million recognized during the first quarter of 2024, (iii) lower employment costs, including incentive compensation and agent commissions, of $1.5 million, and (iv) the absence of expenses associated with Heatlink Group of $1.2 million. These decreases were partially offset by higher legal and professional fees of $1.7 million.

Interest expense was consistent with the first quarter of 2023. Interest income was higher during the first quarter of 2024 primarily as a result of (i) the purchase of short-term investments throughout 2023 and 2024 and (ii) higher rates on deposits. During the first quarters of 2024 and 2023, we recognized gains on the sale of short-term investments of $0.4 million and $1.9 million, respectively. Other expense, net, was consistent with the first quarter of 2023.

Our effective tax rate for the first quarter of 2024 was 26 percent compared with 26 percent for the same period last year. The items impacting the effective tax rate were (i) increases related to the provision for state income taxes, net of the federal benefit, of $5.9 million, (ii) the effect of foreign tax rates higher than statutory tax rates and other foreign items of $1.5 million, and (iii) other items of $2.1 million.

For the first quarter of 2023, the difference between the effective tax rate and the amount computed using the U.S. federal statutory rate was primarily attributable to (i) increases related to the provision for state income taxes, net of the federal benefit, of $7.8 million, (ii) the effect of foreign tax rates higher than statutory tax rates and other foreign items of $2.1 million, and (iii) other items of $1.6 million.

During the first quarter of 2024 and 2023, we recognized net losses of $8.0 million and $1.0 million, respectively, on our investments in unconsolidated affiliates.

Net cash used in financing activities	(52,807)		(19,099)

Cash Flows from Operating Activities

During the quarter ended March 30, 2024, net cash provided by operating activities was primarily attributable to (i) consolidated net income of $141.7 million, (ii) an increase in current liabilities of $33.9 million, (iii) a decrease in inventories of $22.5 million, (iv) non-capital related insurance proceeds of $15.0 million for the March 2023 tornado in Covington, Tennessee, and (v) a decrease in other assets of $12.0 million. There were also increases due to non-cash adjustments primarily consisting of (i) depreciation and amortization of $9.3 million, (ii) losses from unconsolidated affiliates of $8.0 million, and (iii) stock-based compensation expense of $6.2 million. These increases were partially offset by an increase in accounts receivable of $75.2 million.

During the quarter ended April 1, 2023, net cash provided by operating activities was primarily attributable to (i) consolidated net income of $175.1 million, (ii) an increase in current liabilities of $50.8 million, (iii) depreciation and amortization of $10.7 million, and (iv) stock-based compensation expense of $5.6 million. These increases were largely offset by (i) an increase in accounts receivable of $111.5 million and (ii) an increase in other assets of $18.0 million.

Cash Flows from Investing Activities

The major components of net cash provided by investing activities during the quarter ended March 30, 2024 included (i) proceeds from the sale of securities of $96.5 million and (ii) proceeds from the sale of properties of $2.9 million. These sources were partially offset by (i) capital expenditures of $16.4 million and (ii) the issuance of notes receivable of $12.5 million.

The major components of net cash provided by investing activities during the quarter ended April 1, 2023 included (i) proceeds from the maturity of short-term investments of $50.0 million and (ii) insurance proceeds for property and equipment of $8.0 million. These sources were partially offset by capital expenditures of $7.6 million.

Cash Flows from Financing Activities

For the quarter ended March 30, 2024, net cash used in financing activities consisted primarily of (i) $27.9 million used to repurchase common stock, (ii) $22.3 million used for the payment of regular quarterly dividends to stockholders of the Company, and (iii) $2.5 million net cash used to settle stock-based awards.

For the quarter ended April 1, 2023, net cash used in financing activities consisted primarily of (i) $16.7 million used for the payment of regular quarterly dividends to stockholders of the Company and (ii) $2.6 million net cash used to settle stock-based awards.

Liquidity and Outlook

We believe that cash provided by operations, funds available under the Credit Agreement, and cash on hand will be adequate to meet our liquidity needs, including working capital, capital expenditures, and debt payment obligations.

As of March 30, 2024, we had $1.36 billion of cash on hand and $371.1 million available to be drawn under the Credit Agreement. Our current ratio was 6.0 to 1.

We have significant environmental remediation obligations which we expect to pay over future years. Cash used for environmental remediation activities was approximately $0.2 million during the first quarter of 2024. We expect to spend approximately $3.9 million over the next twelve months for ongoing environmental remediation activities.

The Company declared a quarterly cash dividend of 20.0 cents and 15.0 cents per common share during first quarters of 2024 and 2023, respectively. Payment of dividends in the future is dependent upon our financial condition, cash flows, capital requirements, earnings, and other factors.

Long-Term Debt

As of March 30, 2024, the Company’s total debt was $0.8 million or less than one percent of its total capitalization.

The Company’s Credit Agreement provides for an unsecured $400.0 million revolving credit facility, which matures March 31, 2026. There were no borrowings outstanding under the Credit Agreement as of March 30, 2024. The Credit Agreement backed approximately $28.9 million in letters of credit at the end of the first quarter of 2024.

Covenants contained in the Company’s financing obligations require, among other things, the maintenance of minimum levels of tangible net worth and the satisfaction of certain minimum financial ratios. As of March 30, 2024, the Company was in compliance with all of its debt covenants.

Share Repurchase Program

The Board of Directors has extended, until July 2024, the authorization to repurchase up to 40 million shares of the Company’s common stock through open market transactions or through privately negotiated transactions. We may cancel, suspend, or extend the time period for the repurchase of shares at any time. Any repurchases will be funded primarily through existing cash and cash from operations. We may hold any shares repurchased in treasury or use a portion of the repurchased shares for our stock-based compensation plans, as well as for other corporate purposes. From its initial authorization in 1999 through March 30, 2024, the Company has repurchased approximately 15.6 million shares under this authorization.

Contractual Cash Obligations

There have been no significant changes in our contractual cash obligations reported at December 30, 2023.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to market risk from changes in raw material and energy costs, interest rates, and foreign currency exchange rates. To reduce such risks, we may periodically use financial instruments. Hedging transactions are authorized and executed pursuant to policies and procedures. Further, we do not buy or sell financial instruments for trading purposes.

Cost and Availability of Raw Materials and Energy

Raw materials, primarily copper and brass, represent the largest component of the Company’s variable costs of production. The cost of these materials is subject to global market fluctuations caused by factors beyond our control. Significant increases in the cost of metal, to the extent not reflected in prices for our finished products, or the lack of availability could materially and adversely affect our business, results of operations, and financial condition.

The Company occasionally enters into future fixed-price arrangements with certain customers. We may utilize futures contracts to hedge risks associated with these forward fixed-price arrangements. We may also utilize futures contracts to manage price risk associated with inventory. Depending on the nature of the hedge, changes in the fair value of the futures contracts will either be offset against the change in fair value of the inventory through earnings or recognized as a component of accumulated other comprehensive income (AOCI) in equity and reflected in earnings upon the sale of inventory. Periodic value fluctuations of the contracts generally offset the value fluctuations of the underlying fixed-price transactions or inventory. At March 30, 2024, we held open futures contracts to purchase approximately $16.9 million of copper over the next 12 months related to fixed-price sales orders and to sell approximately $106.3 million of copper over the next six months related to copper inventory.

We may enter into futures contracts or forward fixed-price arrangements with certain vendors to manage price risk associated with natural gas purchases. The effective portion of gains and losses with respect to these positions are deferred in equity as a component of AOCI and reflected in earnings upon consumption of natural gas. Periodic value fluctuations of the futures contracts generally offset the value fluctuations of the underlying natural gas prices. As of March 30, 2024, we held no open futures contracts to purchase natural gas.

Interest Rates

At March 30, 2024, we had no variable-rate debt outstanding. At this borrowing level, a hypothetical 10 percent increase in interest rates would have had an insignificant unfavorable impact on our pretax earnings and cash flows. The primary interest rate exposure on variable-rate debt is based on the Secured Overnight Financing Rate (SOFR).

Foreign Currency Exchange Rates

Foreign currency exposures arising from transactions include firm commitments and anticipated transactions denominated in a currency other than an entity’s functional currency. The Company and its subsidiaries generally enter into transactions denominated in their respective functional currencies. We may utilize certain futures or forward contracts with financial institutions to hedge foreign currency transactional exposures. Gains and losses with respect to these positions are deferred in equity as a component of AOCI and reflected in earnings upon collection of receivables or payment of commitments. At March 30, 2024, we had open forward contracts with a financial institution to sell approximately 5.1 million euros, 28.1 million Swedish kronor, and 8.2 million Norwegian kroner through July 2024.

The Company’s primary foreign currency exposure arises from foreign-denominated revenues and profits and their translation into U.S. dollars. The primary currencies to which we are exposed include the Canadian dollar, the British pound sterling, the Mexican peso, the South Korean won, and the Bahraini dinar. The Company generally views its investments in foreign subsidiaries with a functional currency other than the U.S. dollar as long-term. As a result, we generally do not hedge these net investments.

Item 1A. Risk Factors

The Company is exposed to risk as it operates its businesses. To provide a framework to understand the operating environment of the Company, we have provided a brief explanation of the more significant risks associated with our businesses in our 2023 Annual Report on Form 10-K. Except as set forth below, there have been no material changes in risk factors that were previously disclosed in our 2023 Annual Report on Form 10-K. Additionally, the operating results of the Company’s unconsolidated affiliates may be adversely affected by unfavorable economic and market conditions.

Our pending acquisition of Nehring Electrical Works Company and certain of its affiliated companies involves a number of risks, the occurrence of which could adversely affect our business, financial condition, and operating results.

On April 19, 2024, we entered into an equity purchase agreement to acquire Nehring Electrical Works Company and certain of its affiliated companies (collectively, “Nehring”). The acquisition involves certain risks, the occurrence of which could adversely affect our business, financial condition, and operating results, including:



•			delays in completing the acquisition within the expected time period and the risk that the acquisition may not be completed at all;
•			diversion of management's attention to complete the acquisition and integrate Nehring’s operations thereafter;
•			disruption to our existing operations and plans or inability to effectively manage our expanded operations after the closing of the acquisition;
•			potential loss of key Nehring employees, suppliers or customers, or other adverse effects on existing business relationships with suppliers or customers; and
•			our expanded operations may not achieve the growth prospects, synergies or other financial results that we have projected for the acquisition.
