Atkore (NYSE: ATKR) profit slides while strategic review and lawsuits add uncertainty

Rhea-AI Filing Summary

Atkore Inc. reported a sharp profit decline for the quarter ended December 26, 2025. Net sales were nearly flat at $655.5 million versus $661.6 million a year earlier, but net income fell to $15.0 million from $46.3 million. Diluted earnings per share dropped to $0.44 from $1.31.

Gross profit decreased 26.4% as cost of sales rose 8.0% on higher input costs and extra depreciation tied to plant closures. Electrical segment Adjusted EBITDA fell 40.4% to $55.1 million, while Safety & Infrastructure nearly doubled Adjusted EBITDA to $30.2 million on better operations. Cash from operations swung to an outflow of $55.5 million, though the company ended the quarter with $443.8 million in cash and an undrawn $325.0 million ABL facility.

Atkore completed the sale of Tectron Tube, recognizing a $2.3 million gain, and continued restructuring that increased charges and depreciation. The company also disclosed ongoing antitrust, securities class action and derivative lawsuits, plus a DOJ antitrust subpoena, and noted its board is reviewing strategic alternatives, including a potential sale or merger.

Positive

• Safety & Infrastructure margin improvement: Safety & Infrastructure Adjusted EBITDA nearly doubled to $30.2 million, with margin rising to 16.2% from 7.9%, reflecting improved operational performance and cost control in mechanical and construction businesses.
• Strong liquidity position: The company held $443.8 million of cash and cash equivalents and had the full $325.0 million ABL Credit Facility available, supporting funding for operations, restructuring and potential strategic transactions.

Negative

• Significant earnings and margin decline: Net income fell 67.6% to $15.0 million and diluted EPS dropped to $0.44, while gross margin contracted as higher input costs and elevated depreciation pressured profitability, particularly in the Electrical segment.
• Weak operating cash flow: Net cash from operating activities deteriorated from a $74.4 million inflow to a $55.5 million outflow, reflecting lower earnings and working capital usage, reducing internally generated funding capacity in the quarter.
• Restructuring and portfolio review costs: Headcount reductions and plant closures drove higher restructuring charges and an $8.2 million depreciation increase, and a broader strategic review is expected to add ongoing transaction-related expenses.
• Legal and regulatory overhang: The company faces PVC-related antitrust class actions, securities and derivative lawsuits, and a DOJ antitrust subpoena regarding PVC pricing, with management noting that adverse outcomes could materially impact business, financial position, results or cash flows.

Insights

Equity analyst

Profitability and cash generation weakened materially despite stable sales.

Atkore held revenue roughly flat at $655.5 million, but net income fell 67.6% to $15.0 million. Margin compression came from higher input costs and an $8.2 million step-up in depreciation linked to announced plant closures, which cut Electrical segment Adjusted EBITDA margin from 19.9% to 11.7%.

Operating cash flow deteriorated from a $74.4 million inflow to a $55.5 million outflow, driven by lower earnings and working capital movements, even as cash on hand remained strong at $443.8 million. The Safety & Infrastructure segment was a bright spot, nearly doubling Adjusted EBITDA to $30.2 million with margin of 16.2%, helped by operational improvements and solar tax credits.

Looking ahead, restructuring actions and the portfolio review may continue to affect depreciation, restructuring expense and transaction costs in subsequent quarters, while ample liquidity and an undrawn $325.0 million ABL facility provide financial flexibility for potential strategic outcomes and ongoing capital needs.

Special situations & governance analyst

Strategic review and legal overhang add uncertainty to the story.

The board is conducting a strategic alternatives review, including a possible sale or merger of the whole company, with no set timetable. This introduces uncertainty around future control and capital allocation, and the company expects to incur substantial related transaction and advisory costs.

Atkore also reports being a defendant in PVC-related antitrust class actions in the U.S. and Canada, securities class actions, and derivative suits, and has received a DOJ Antitrust Division grand jury subpoena on PVC pricing. Outcomes and potential losses are not quantifiable at this stage, but the company acknowledges an adverse result could materially affect its business, financial position or cash flows.

These legal and strategic processes may influence future expense levels, management attention and potential deal structures, with further detail expected only as courts or the board reach key milestones or decisions disclosed in subsequent company filings.

ATKORE INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

(dollars and shares in thousands, except per share data)

1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Organization and Ownership Structure — Atkore Inc. (the “Company”, “Atkore” or “AI”) is a leading manufacturer of Electrical products primarily for the non-residential construction and renovation markets and Safety & Infrastructure solutions for the construction and industrial markets. Atkore was incorporated in the State of Delaware on November 4, 2010 under the name Atkore International Group, Inc. and changed its name to Atkore Inc. on February 16, 2021. As of December 26, 2025, Atkore was the sole stockholder of Atkore International Inc. ("AII").

The Electrical segment manufactures high quality products used in the construction of electrical power systems including conduit, cable, and installation accessories. This segment serves contractors, in partnership with the electrical wholesale channel.

The Safety & Infrastructure segment designs and manufactures solutions including metal framing, mechanical pipe, perimeter security, and cable management for the protection and reliability of critical infrastructure. These solutions are marketed to contractors, original equipment manufacturers and end users.

Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of the Company included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These unaudited condensed consolidated financial statements have been prepared in accordance with the Company’s accounting policies and on the same basis as those consolidated financial statements included in the Company’s latest Annual Report on Form 10-K for the year ended September 30, 2025, filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 26, 2025, and should be read in conjunction with those consolidated financial statements and the notes thereto. Certain information and disclosures normally included in the Company’s annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC.

The unaudited condensed consolidated financial statements include the assets and liabilities used in operating the Company’s business. All intercompany balances and transactions have been eliminated in consolidation. The results of companies acquired or disposed of are included in the unaudited condensed consolidated financial statements from the effective date of acquisition or up to the date of disposal.

These statements include all adjustments (consisting of normal recurring adjustments) that the Company considered necessary to present a fair statement of its results of operations, financial position and cash flows. The results reported in these unaudited condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the entire year.

Fiscal Periods — The Company has a fiscal year that ends on September 30. The Company’s fiscal quarters typically end on the last Friday in December, March and June as it follows a 4-5-4 calendar.

Use of Estimates — The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclose contingent assets and liabilities at the date of the condensed consolidated financial statements and report the associated amounts of revenues and expenses. Actual results could differ materially from these estimates.

Recent Accounting Pronouncements

A summary of recently adopted accounting guidance is as follows. Adoption dates are on the first day of the fiscal year indicated below, unless otherwise specified.

ASU

Description of ASU

Impact to Atkore

Adoption Date

2023-09 Income Taxes (Topic 740); Improvements to Income Tax Disclosures

The ASU requires companies to provide additional tax disclosures including specific categories in the rate reconciliations and reconciling items that meet a quantitative threshold. Additional disclosures are also required for income tax paid and the disaggregation of domestic and foreign income tax expense.

The Company has adopted the standard in fiscal 2026 and include the disclosures required by the ASU within the Income Tax Footnote of the annual report.

2026

2024-03 Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40)

The ASU requires companies to disclose, in the notes to the financial statements, specified information about certain costs and expenses. The amendments in this update do not change or remove current expense disclosure requirements presented on the face of the income statement. However, the amendments require the disaggregation of certain expense captions into specified categories in the notes to financial statements and inclusion of certain current disclosures in the same tabular format as the other disaggregation requirements in the amendments.

The Company will adopt the standard in fiscal 2028 and include the disclosures required by the ASU within the annual report and quarterly reports beginning in fiscal 2029.

2028

2025-06 Intangibles - Goodwill and Other-Internal-Use Software (Subtopic 350-40); Targeted Improvements to the Accounting for Internal-Use Software

This ASU requires companies to consider project stages in determining whether a software development cost for internal-use software is capitalized or expensed. The amendment requires an entity to start capitalizing software costs when management has both authorized and committed to funding the software project and when it is probable that the project will be completed and the software will be used to perform the intended function. Additionally, disclosures are required for all capitalized internal-use software costs, regardless of how those costs are presented in the financial statements in accordance with Subtopic 360-10, Property, Plant, and Equipment - Overall.

The Company is still evaluating the future impact of this accounting standard.

2029

2. REVENUE FROM CONTRACTS WITH CUSTOMERS

The Company’s revenue arrangements primarily consist of a single performance obligation to transfer promised goods which is satisfied at a point in time when title, risks and rewards of ownership, and subsequently control have transferred to the customer. This generally occurs when the product is shipped to the customer, with an immaterial amount of transactions in which control transfers upon delivery. The Company primarily offers assurance-type standard warranties that do not represent separate performance obligations.

9

Under the Inflation Reduction Act of 2022 (“IRA”), the Company is eligible for tax credits related to the manufacturing and selling of components used in the solar energy industry. These tax credits are transferable under the IRA when they meet certain criteria. When credits do not meet the transferability criteria, the benefit is recognized within income tax expense in accordance with ASC 740, “Income Taxes.” Beginning in fiscal 2024, the Company has concluded that the credits generated are transferable. As such, the benefit of the solar energy tax credits is recognized as a reduction of cost of sales.

The Company has contractual arrangements with certain customers to transfer a portion of the tax credits or to otherwise provide a rebate based on an agreed-upon value of the tax credits generated. Pursuant to such contractual arrangements, if the tax credits will be transferred to the customer, the Company identifies two separate performance obligations: (1) transfer the promised goods; and (2) transfer of the defined portion of the tax credits earned. The Company allocates the total value of these transactions between the two performance obligations. As a result of this allocation, the Company recognizes a reduction to revenue, similar to a rebate. For arrangements with no transfer of tax credits there is only a single performance obligation to transfer the promised goods and a rebate, which is recognized as a reduction of revenue, is granted based on the agreed-upon value of the tax credits generated.

The solar energy tax credit receivable is recorded in Prepaid Expenses and Other Current Assets and the liability to transfer the defined portion of the tax credits or the economic value thereof is recorded in Customer Liabilities.

For the three months ended December 26, 2025, the Company has recognized a reduction of revenue of $12,525 for the economic value of tax credits to be transferred and a benefit to cost of sales of $13,538. As of December 26, 2025, the Company had a liability of $12,981 for credits to be transferred or the value thereof. As of December 26, 2025, all activity related to the solar energy tax credits was within the Safety & Infrastructure segment.

The Company has certain arrangements that require it to estimate at the time of sale the amounts of variable consideration that should not be recorded as revenue as certain amounts are not expected to be collected from customers, as well as an estimate of the value of products to be returned. The Company principally relies on historical experience, specific customer agreements, and anticipated future trends to estimate these amounts at the time of sale and to reduce the transaction price. These arrangements include sales discounts and allowances, volume rebates, and returned goods. The Company records its obligations related to these items within the Customer Liabilities line on the condensed consolidated balance sheets.

The Company records amounts billed to customers for reimbursement of shipping and handling costs within revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of goods sold. Sales taxes and other usage-based taxes are excluded from revenue. The Company does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year. The Company also expenses costs incurred to obtain a contract, primarily sales commissions, as all obligations will be settled in less than one year.

The Company typically receives payment 30 to 60 days from the point it has satisfied the related performance obligation. See Note 17, “Segment Information” for revenue disaggregated by geography and product categories.

3. DIVESTITURES

On December 1, 2025, the Company sold Tectron Tube. The transaction was structured as a stock sale.

(in thousands)						Tectron Tube
Cash consideration						$	18,388
Note received						7,300
Net assets divested						23,273
Gain on sale of business						$	2,415

Net assets divested included working capital of $14,727, fixed assets, net of $8,545, and right-of-use assets and lease liabilities of $387 and $386, respectively. Working capital primarily included accounts receivables, net of $3,971, and inventory, net of $10,227. For consideration, the Company received cash of $18,388 and a note receivable of $7,300 payable in April 2026.

In fiscal 2023, the Company initiated plans to exit operations in Russia and that asset disposal group was recognized as assets held for sale. The Company recognized losses on those assets in fiscal 2023 as the Company did not expect to recover the value of its investment. The Company completed its exit in the first quarter of fiscal 2026 and recognized a loss on sale of business of $140.

4. POSTRETIREMENT BENEFITS

The Company provides pension benefits through a number of noncontributory and contributory defined benefit retirement plans covering eligible U.S. employees. As of September 30, 2017, all defined pension benefit plans were frozen, whereby participants no longer accrue credited service.

The net periodic benefit credit was as follows: 

						Three months ended
(in thousands)						December 26, 2025						December 27, 2024
Interest cost						$	1,118					$	1,139
Expected return on plan assets						(1,254)						(1,081)
Amortization of actuarial loss						62						52
Net periodic benefit cost						$	(74)					$	110

5. RESTRUCTURING CHARGES

On September 29, 2025, the Company announced plans for headcount reductions and plant closures at certain of its facilities. The following tables summarize the activities related to the plan.

The liability for restructuring reserves is included within Other current liabilities in the Company's condensed consolidated balance sheets as follows: 

						Electrical												Safety & Infrastructure						Other/ Corporate
(in thousands)						Severance						Other						Severance						Severance						Total
Balance as of September 30, 2025						$	845					$	—					$	227					$	257					$	1,329
Charges						445						167						928						(13)						1,527
Utilization						(772)						(162)						(245)						(244)						(1,423)
Balance as of December 26, 2025						$	518					$	5					$	910					$	—					$	1,433

The Company expects to utilize all restructuring accruals as of December 26, 2025 within the next twelve months. The net restructuring charges included as a component of Selling, general and administrative expenses in the Company's condensed consolidated statements of operations were as follows:

						Three months ended
(in thousands)						December 26, 2025						December 27, 2024
Total restructuring charges, net						$	1,527					$	321

In addition to the charges presented above, the Company reduced the remaining useful lives of assets still in use at the plants that are closing in fiscal 2026. This resulted in an additional $8,165 of depreciation expense to be recognized in the first quarter of 2026. Depreciation of plant assets is recognized in Cost of sales.

6. OTHER (INCOME) EXPENSE, NET

Other (income) expense, net consisted of the following:

						Three months ended

Loss on assets held for sale						$	—					$	68
Foreign exchange loss on intercompany loans						—						1,021
Pension-related benefits						(52)						44
(Gain) on sale of business						(2,275)						—
Other (income) expense, net						$	(2,327)					$	1,133

In fiscal 2026, the Company divested Tectron Tube and operations in Russia and recognized a gain of $2,275 as described in Note 3, “Divestitures”.

12

7. INCOME TAXES    

For the three months ended December 26, 2025 and December 27, 2024, the Company’s effective tax rate attributable to income before income taxes was 3.0% and 20.9%, respectively. For the three months ended December 26, 2025 and December 27, 2024, the Company’s income tax expense was $465 and $12,260, respectively. The decrease in the current period effective tax rate was driven by a one-time discrete tax benefit related to tax planning strategies which resulted in deductible tax attributes.

A valuation allowance has been recorded against certain net operating losses in certain foreign jurisdictions. A valuation allowance is recorded when it is determined to be more likely than not that these assets will not be fully realized in the foreseeable future. The realization of deferred tax assets is dependent upon whether the Company can generate future taxable income in the appropriate character and jurisdiction to utilize the assets. The amount of the deferred tax assets considered realizable is subject to adjustment in future periods.

8. EARNINGS PER SHARE

The Company calculates basic and diluted earnings per common share using the two-class method. Under the two-class method, net earnings are allocated to each class of common stock and participating securities as if all of the net earnings for the period had been distributed. The Company’s participating securities consist of share-based payment awards that contain a non-forfeitable right to receive dividends and therefore are considered to participate in undistributed earnings with common stockholders.

Basic earnings per common share excludes dilution and is calculated by dividing the net earnings allocated to common stock by the weighted-average number of common stock outstanding for the period. Diluted earnings per common share is calculated by dividing net earnings allocated to common stock by the weighted-average number of shares outstanding for the period, as adjusted for the potential dilutive effect of non-participating share-based awards.

The following tables sets forth the computation of basic and diluted earnings per share:

						Three months ended
(in thousands, except per share data)						December 26, 2025						December 27, 2024
Numerator:
Net income						$	15,034					$	46,336
Less: Undistributed earnings allocated to participating securities						77						557
Net income available to common shareholders						$	14,957					$	45,779
Denominator:
Basic weighted average common shares outstanding						33,706						34,794
Effect of dilutive securities: Non-participating employee stock options (1)						199						246
Diluted weighted average common shares outstanding						33,905						35,040
Basic earnings per share						$	0.44					$	1.32
Diluted earnings per share						$	0.44					$	1.31
(1) Stock options to purchase shares of common stock that would have been anti-dilutive are not included in the calculation. There were no anti-dilutive options outstanding during the three months ended December 26, 2025 and December 27, 2024.

10. INVENTORIES, NET

A majority of the Company’s inventories are recorded at the lower of cost (primarily last in, first out, or “LIFO”) or market or net realizable value, as applicable. Approximately 82% and 81% of the Company’s inventories were valued at the lower of LIFO cost or market at each of December 26, 2025 and September 30, 2025. Interim LIFO determinations, including those at December 26, 2025, are based on management’s estimates of future inventory levels and costs for the remainder of the current fiscal year.

Balance as of December 26, 2025						$	261,116					$	33,760					$	294,876

Goodwill balances as of December 26, 2025 included $5,645 and $61,885 of accumulated impairment losses within the Electrical and Safety & Infrastructure segments, respectively.

The Company assesses the recoverability of goodwill and indefinite-lived trade names on an annual basis in accordance with ASC 350, “Intangibles - Goodwill and Other.” The measurement date is the first day of the fourth fiscal quarter, or more frequently, if events or circumstances indicate that it is more likely than not that the fair value of a reporting unit or the respective indefinite-lived trade name is less than the carrying value.

Other intangible assets consist of definite-lived trade names, technology, non-compete agreements and backlogs. Included in the table above are the effects of changes in exchange rates, which were not material for the three months ended December 26, 2025. Amortization expense for the three months ended December 26, 2025 and December 27, 2024 was $6,310 and $11,699, respectively.

Expected amortization expense for intangible assets for the remainder of fiscal 2026 and over the next five years and thereafter is as follows:

13. DEBT

Debt as of December 26, 2025 and September 30, 2025 was as follows:

(in thousands)						December 26, 2025						September 30, 2025
ABL Credit Facility						$	—					$	—
Senior Secured Term Loan Facility due September 29, 2032						370,712						370,628
Senior Notes due June 2031						400,000						400,000
Deferred financing costs						(9,659)						(10,096)
Total debt						$	761,053					$	760,532
Less: Current portion						3,730						3,730
Long-term debt						$	757,323					$	756,802

The asset-based credit facility (the “ABL Credit Facility”) has aggregate commitments of $325,000. AII is the borrower under the ABL Credit Facility which is guaranteed by the Company and all other subsidiaries of the Company (other than AII) that are guarantors of the Senior Notes (as defined below). AII’s availability under the ABL Credit Facility was $325,000 as of each of December 26, 2025 and September 30, 2025.

The ABL Credit Facility uses a forward-looking interest rate based on the Secured Overnight Financing Rate (“SOFR”) consisting of an applicable margin ranging from 1.25% to 1.75% and a credit spread adjustment of 0.10%.

On April 30, 2025, AII, a wholly owned subsidiary of the Company, entered into a Fourth Amendment to its existing Credit Agreement, dated as of August 28, 2020, which, among other things, (i) extended the maturity of the facility to the earlier of April 30, 2030 or 91 days prior to the maturity date of the existing senior term loan facility if at least $100,000 of obligations remain outstanding under the existing senior secured term loan facility on such date and (ii) amended certain terms and thresholds with respect to the Company’s borrowing base capacity.

On March 15, 2023, the Company entered into an amendment to the New Senior Secured Term Loan Facility to implement a forward-looking interest rate based on the Secured Overnight Financing Rate (“SOFR”) in lieu of LIBOR, consisting of an applicable margin of 2.00% and a credit spread adjustment of (i) 0.11448% for a one-month interest period, (ii) 0.26161% for a three-month interest period and (iii) 0.42826% for a six-month interest period.

On September 29, 2025, the Company entered into a new $373 million senior secured term loan facility (the “New Senior Secured Term Loan Facility”) pursuant to an amendment to its existing Term Loan Credit Agreement (the “Amendment”). The New Senior Secured Term Loan Facility will mature on the earlier of (i) September 29, 2032 and (ii) the date that is 91 days prior to the maturity of the Company’s existing senior notes due June 1, 2031 if more than $100 million of such senior notes remains outstanding as of such date. Borrowings under the New Senior Secured Term Loan Facility will bear interest at the rate of either (x) Term SOFR (with a floor of 0%) plus 2.00%, or (y) an alternate base rate (with a floor of 1.5%) plus 1.00%. The New Senior Secured Term Loan Facility has an annual amortization rate of 1.00%.

Senior Notes - On May 26, 2021, the Company completed the issuance and sale of the $400,000 aggregate principal amount of 4.25% Senior Notes due 2031 (the “Senior Notes”) in a private offering. The Senior Notes were sold only to qualified institutional buyers in compliance with Rule 144A of the Securities Act of 1933, as amended (the “Securities Act”), and to non-U.S. persons outside of the United States in compliance with Regulation S of the Securities Act.

14. FAIR VALUE MEASUREMENTS

Certain assets and liabilities are required to be recorded at fair value on a recurring basis.

The Company periodically uses forward currency contracts to hedge the effects of foreign exchange relating to intercompany balances denominated in a foreign currency. These derivative instruments are not formally designated as a hedge by the Company. Short-term forward currency contracts are recorded in either other current assets or other current liabilities and long-term forward currency contracts are recorded in either other long-term assets or other long-term liabilities in the condensed consolidated balance sheets. The fair value gains and losses are included in other (income) expense, net within the condensed consolidated statements of operations. See Note 6, “Other (Income) Expense, net” for further detail.

Cash flows associated with derivative financial instruments are recognized in the operating section of the condensed consolidated statements of cash flows. The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles.

The Company had no active forward currency contracts or other derivative instruments as of December 26, 2025, or September 30, 2025.

The following table presents the Company’s assets and liabilities measured at fair value:

						December 26, 2025												September 30, 2025
(in thousands)						Level 1						Level 2						Level 1						Level 2
Assets
Cash equivalents						$	375,937					$	—					$	422,292					$	—

The Company’s remaining financial instruments consist primarily of cash, accounts receivable and accounts payable whose carrying value approximate their fair value due to their short-term nature.

The estimated fair value of financial instruments not carried at fair value in the condensed consolidated balance sheets were as follows:

						December 26, 2025												September 30, 2025
(in thousands)						Carrying Value						Fair Value						Carrying Value						Fair Value
Senior Secured Term Loan Facility due September 29, 2032						$	373,000					$	374,399					$	373,000					$	371,135
Senior Notes due June 2031						400,000						384,260						400,000						373,164
Total Debt						$	773,000					$	758,659					$	773,000					$	744,299

In determining the approximate fair value of its long-term debt, the Company used the trading values among financial institutions, and these values fall within Level 2 of the fair value hierarchy. The carrying value of the ABL Credit Facility approximates fair value due to it being a market-linked variable rate debt.

15. COMMITMENTS AND CONTINGENCIES

The Company has obligations related to commitments to purchase certain goods. As of December 26, 2025, such obligations were $230,331 for the rest of fiscal year 2026 and $16,000 for fiscal year 2027 and beyond. These amounts represent open purchase orders for materials used in production.

18

Insurable Liabilities — The Company maintains policies with various insurance companies for its workers’ compensation, product, property, general, auto, and executive liability risks. The insurance policies that the Company maintains have various retention levels and excess coverage limits. The establishment and update of liabilities for unpaid claims, including claims incurred but not reported, is based on management's estimate as a result of the assessment by the Company's claim administrator of each claim and an independent actuarial valuation of the nature and severity of total claims. The Company utilizes a third-party claims administrator to pay claims, track and evaluate actual claims experience, and ensure consistency in the data used in the actuarial valuation.

Legal Contingencies — Historically, a number of lawsuits have been filed against the Company and the Company has also received other claim demand letters alleging that the Company's anti-microbial coated steel sprinkler pipe, which the Company has not manufactured or sold for several years, is incompatible with chlorinated polyvinyl chloride and caused stress cracking in such pipe manufactured by third parties when installed together in the same sprinkler system, which the Company refers to collectively as the “Special Products Claims.” Tyco International Ltd., now Johnson Controls, Inc. (“JCI”), has a contractual obligation to indemnify the Company in respect of all remaining and future claims of incompatibility between the Company's antimicrobial coated steel sprinkler pipe and CPVC pipe used in the same sprinkler system. When Special Products Claims arise, JCI has defended and indemnified the Company as required.

As of the date of this filing, no Special Product Claims are currently pending against the Company as JCI has resolved all claims at their sole cost and expense. Accordingly, at this time, the Company does not expect the outcome of the Special Products Claims proceedings, either individually or in the aggregate, to have a material adverse effect on its business, financial condition, results of operations or cash flows, and the Company believes that its reserves are adequate for all remaining contingencies for Special Products Claims and other product liabilities.

In the fourth quarter of fiscal 2024, the Company was named a defendant in several putative class action lawsuits, consolidated under the caption In re: PVC Pipe Antitrust Litigation (N.D. Ill. 24-cv-07639), seeking injunctive and monetary relief on behalf of both direct and indirect purchasers of PVC water pipe and PVC conduit. The suits generally allege anticompetitive conduct related to the price of PVC pipes sold in the United States between approximately 2021 and the present. Specifically, the complaints allege that the defendant PVC pipe manufacturers improperly shared otherwise confidential information through their contribution of information to, and readership of, a weekly report called “PVC & Pipe Weekly” published by defendant Oil Price Information Service, LLC (“OPIS”), as well as through direct communications with each other. The complaints claim that this conspiracy violated Section 1 of the Sherman Antitrust Act of 1890, as amended, and certain state laws. All cases are pending in federal court for the Northern District of Illinois. The Company believes there are defenses, both factual and legal, to the allegations in these various proceedings and the Company plans to vigorously defend itself. A settlement between OPIS and plaintiffs was preliminarily approved in July 2025, obligating OPIS to pay certain monies and to cooperate with plaintiffs. Notice of the settlement has been sent to class members who now have the opportunity to opt out. Amended complaints were filed in August 2025 that included additional allegations against the defendants, including the Company. Defendants have filed motions to dismiss the amended complaints, and briefing on these motions is complete.

At this stage of the antitrust litigation, the Company cannot reasonably estimate the range of possible loss or timing, outcome or consequence of this litigation. The total cost associated with these matters will depend on many factors, including the duration of these matters and any related findings. An adverse outcome in this litigation could have a material adverse impact on the Company’s business, financial position, results of operations or cash flows.

In September 2025, the Company was also named a defendant in a lawsuit in British Columbia, Canada with allegations similar to those in the US antitrust lawsuits. At this time, the Company is not able to predict any outcome or estimate the amount of loss, if any, which could be associated with any adverse decision in this matter.

19

On February 13, 2025, the Company received from the U.S. Department of Justice Antitrust Division (“DOJ”) a grand jury subpoena issued by the U.S. District Court for the Northern District of California. The subpoena calls for production of documents relating to the pricing of the Company’s PVC pipe and conduit products. The Company is complying, and intends to continue to comply, with its obligations under the subpoena. In October 2025, the DOJ intervened and sought an order from the court presiding over the putative antitrust class action lawsuits, staying most discovery in these matters for six months. DOJ’s motion to stay discovery was granted without objection.

In the second quarter of fiscal 2025, the Company and certain of its current and former officers were named as defendants in two putative securities class action lawsuits under the captions Westchester Putnam Counties Heavy & Highway Laborers Local 60 Benefits Fund v. Atkore Inc. et al (N.D. Ill 1:25-cv-01851) and Coles v. Atkore Inc. et al (N.D. Ill 1:25-cv-02686). The complaints assert claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Rule 10(b)(5) promulgated thereunder, based on disclosures about the Company’s business, operations, and prospects, which were allegedly false or misleading based on the allegations in the antitrust matters described above. The complaints seek damages in an unspecified amount on behalf of all shareholders who purchased shares during the class period. An amended complaint was filed in August 2025, and a further amended complaint was filed in December 2025. The Company believes there are defenses, both factual and legal, to the allegations in these proceedings, and the Company plans to vigorously defend the cases.

Also, in the second quarter of fiscal 2025, a putative shareholder derivative lawsuit was filed naming the Company as the nominal defendant under the caption Blatzer v. Waltz et al (N.D. Ill 1:25-cv-02833). The Company’s directors and certain of its current and former officers are named as defendants. A second such lawsuit was recently filed under the caption LR Trust v. Waltz et al (N.D. III 1:25-cv-08009). These complaints assert claims for breach of fiduciary duties, aiding and abetting breach of fiduciary duties, unjust enrichment, waste, and violations of federal securities laws, and in LR Trust, an insider trading claim, based primarily on the same alleged conduct underlying the securities class action lawsuits described above, and seek damages in an unspecified amount and other relief.

At this stage of the securities or derivative litigation, the Company cannot reasonably estimate the range of possible loss or the timing, outcome or consequence of the securities or derivative proceedings described above. The total cost associated with these matters will depend on many factors, including the duration of these matters and any related findings. An adverse outcome in this litigation could have a material adverse impact on the Company’s business, financial position, results of operations or cash flows.

In addition to the matters discussed above, from time to time, the Company is subject to a number of disputes, administrative proceedings and other claims arising out of the ordinary conduct of the Company’s business. These matters generally relate to disputes arising out of the use or installation of the Company’s products, product liability litigation, contract disputes, patent infringement accusations, employment matters, personal injury claims and similar matters (“Other Matters”). On the basis of information currently available to the Company, it does not believe that existing Other Matters will have a material adverse effect on its business, financial condition, results of operations or cash flows. However, litigation is unpredictable, and the Company could incur judgments or enter into settlements for current or future claims that could adversely affect its business, financial condition, results of operations or cash flows.

16. GUARANTEES

The Company had no outstanding letters of credit as of December 26, 2025. The Company also had surety bonds primarily related to performance guarantees on supply agreements and construction contracts, and payment of duties and taxes totaling $44,381 as of December 26, 2025.

In disposing of assets or businesses, the Company often provides representations, warranties and indemnities to cover various risks including unknown damage to the assets, environmental risks involved in the sale of real estate, liability to investigate and remediate environmental contamination at

20

waste disposal sites and manufacturing facilities, and unidentified tax liabilities and legal fees related to periods prior to disposition. The Company does not have the ability to estimate the potential liability from such indemnities because they relate to unknown conditions. However, the Company has no reason to believe that these uncertainties would have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

In the normal course of business, the Company is liable for product performance and contract completion. In the opinion of management, such obligations will not have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

17. SEGMENT INFORMATION

Atkore operates its business through two operating segments which are also its reportable segments: Electrical and Safety & Infrastructure. The Company’s operating segments are organized based on primary market channel and, in most instances, the end use of products. The Company reviews the results of its operating segments separately for the purpose of making decisions about resource allocation and performance assessment. The Company evaluates performance on the basis of net sales and Adjusted EBITDA.

The Electrical segment manufactures high quality products used in the construction of electrical power systems including conduit, cable and installation accessories. This segment serves contractors in partnership with the electrical wholesale channel.

The Safety & Infrastructure segment designs and manufactures solutions including metal framing, mechanical pipe, perimeter security and cable management for the protection and reliability of critical infrastructure. These solutions are marketed to contractors, original equipment manufacturers and end users.

The Company’s Chief Operating Decision Maker (“CODM”) is the President and Chief Executive Officer. The CODM uses Adjusted EBITDA to allocate resources predominantly in the annual planning process. Adjusted EBITDA is used to monitor and evaluate periodic results against budget, forecast and prior period results.

Both segments use Adjusted EBITDA as the primary measure of profit and loss. Segment Adjusted EBITDA is income (loss) before income taxes, adjusted to exclude unallocated expenses, depreciation and amortization, interest expense, net, stock-based compensation, loss on extinguishment of debt, gains and losses on the divestiture of a business, asset impairment charges, certain legal matters, and other items, such as inventory reserves and adjustments, (gain) loss on disposal of property, plant and equipment, insurance recovery related to damages of property, plant and equipment, release of indemnified uncertain tax positions, realized or unrealized gain (loss) on foreign currency impacts of intercompany loans and related forward currency derivatives, gain on purchase of business, loss on assets held for sale, restructuring costs and transaction costs.

Intersegment transactions primarily consist of product sales at designated transfer prices on an arm’s-length basis. Gross profit earned and reported within the segment is eliminated in the Company’s consolidated results. Certain manufacturing and distribution expenses are allocated between the segments on a pro rata basis due to the shared nature of activities. Recorded amounts represent a proportional amount of the quantity of product produced for each segment. Certain assets, such as machinery and equipment and facilities, are not allocated to each segment despite serving both segments. These shared assets are reported within the Safety & Infrastructure segment. The Company allocates certain corporate operating expenses that directly benefit our operating segments, such as insurance and information technology, on a basis that reasonably approximates an estimate of the use of these services.

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

The following information should be read in conjunction with the unaudited condensed consolidated financial statements and related notes included in this report. The following discussion may contain forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to these differences include those factors discussed below and included or referenced elsewhere in this report, particularly in the sections entitled “Forward-Looking Statements” and “Risk Factors.”

Incremental Market Uncertainties

Recent events, including the imposition of tariffs and other changes in international trade policy, central bank interest rate adjustments, inflation, and conflicts in Ukraine and the Middle East are creating additional uncertainty in the global economy, generally, and in the markets we operate in. The aforementioned conflicts and other factors have had and will continue to have adverse effects on global supply chains, which may impact some aspects of our business. Furthermore, we are mindful of the effects that adverse weather can have on our domestic supply chain.

Restructuring and Strategic Review

In fiscal 2025, the Company announced a series of plant closures and a broader strategic review of the Company’s portfolio, which could result in the divestiture of certain businesses. Restructuring costs and activities related to the strategic review could result in increased selling, general and administrative costs in the form of restructuring and transaction costs, as well increased costs of sales as the result of increased depreciation related to a decrease in useful lives of assets at impacted sites. Furthermore, these activities could result in the Company recognizing impairment charges on property, plant and equipment, intangible assets or goodwill.

RESULTS OF OPERATIONS

The consolidated results of operations for the three months ended December 26, 2025 and December 27, 2024 were as follows:

			Three months ended

24

Net sales

						% Change
Volume						2.3		%
Average selling prices						(2.7)		%
Other						(0.5)		%
Net sales						(0.9)		%

Net sales decreased by $6.0 million, or 0.9%, to $655.5 million for the three months ended December 26, 2025, compared to $661.6 million for the three months ended December 27, 2024. The decrease in net sales is primarily attributed to decreased average selling prices across the Company’s products of $18.1 million and the impact of divestitures in fiscal 2025 of $5.2 million, partially offset by increased sales volume of $15.3 million.

Cost of sales

						% Change
Volume						3.1		%
Average input costs						5.2		%
Other						(0.3)		%
Cost of sales						8.0		%

Cost of sales increased by $39.1 million, or 8.0%, to $529.6 million for the three months ended December 26, 2025 compared to $490.5 million for the three months ended December 27, 2024. The increase was primarily due to increased sales volume of $15.2 million, increased inputs costs of $25.3 million, and increased depreciation of $11.8 million partially offset by lower freight and warehousing costs of $15.1 million and the impact of divestitures in fiscal 2025 of $5.7 million. The increase in depreciation primarily relates to additional depreciation of $8.2 million related to site closures as described in Note 5, “Restructuring Charges.”

Selling, general and administrative

Selling, general and administrative expenses increased by $8.1 million, or 8.9%, to $99.6 million for the three months ended December 26, 2025 compared to $91.5 million for the three months ended December 27, 2024. The increase was primarily due to increased transaction costs of $6.3 million and restructuring costs of $1.2 million.

Intangible asset amortization

Intangible asset amortization expense decreased to $6.3 million for the three months ended December 26, 2025 compared to $11.7 million for the three months ended December 27, 2024. The decrease in amortization expense resulted from certain intangibles becoming fully amortized or the amortizable base decreasing as a result of impairment charges recorded in fiscal 2025.

Interest expense, net

Interest expense, net decreased by $1.3 million, or 16.0% to $6.9 million for the three months ended December 26, 2025 compared to $8.2 million for the three months ended December 27, 2024. The decrease is primarily due to decreased interest rates on the Company’s Senior Secured Term Loan Facility.

Other (income) expense, net

The Company recognized $2.3 million of other income for the three months ended December 26, 2025 compared to $1.1 million other expense for the three months ended December 27, 2024. This change is primarily due to a gain on the sale of Tectron Tube of $2.3 million in the first quarter of fiscal 2026.

25

Income tax expense

The Company’s income tax rate decreased to 3.0% for the three months ended December 26, 2025 compared to 20.9% for the three months ended December 27, 2024. The decrease in the current period effective tax rate was driven by a one-time discrete tax benefit related to tax planning strategies which resulted in deductible tax attributes.

SEGMENT RESULTS

The Electrical segment manufactures high quality products used in the construction of electrical power systems including conduit, cable and installation accessories. This segment serves contractors in partnership with the electrical wholesale channel.

The Safety & Infrastructure segment designs and manufactures solutions including metal framing, mechanical pipe, perimeter security and cable management for the protection and reliability of critical infrastructure. These solutions are marketed to contractors, original equipment manufacturers and end users.

Both segments use Adjusted EBITDA as the primary measure of profit and loss. Segment Adjusted EBITDA is income (loss) before income taxes, adjusted to exclude unallocated expenses, depreciation and amortization, interest expense, net, stock-based compensation, loss on extinguishment of debt, gains and losses on the divestiture of a business, asset impairment charges, certain legal matters, and other items, such as inventory reserves and adjustments, (gain) loss on disposal of property, plant and equipment, insurance recovery related to damages of property, plant and equipment, release of indemnified uncertain tax positions, realized or unrealized gain (loss) on foreign currency impacts of intercompany loans and related forward currency derivatives, gain on purchase of business, loss on assets held for sale, restructuring costs and transaction costs. We define segment Adjusted EBITDA margin as segment Adjusted EBITDA as a percentage of segment Net sales.

The increase in net sales is primarily attributed to increased sales volume of $23.4 million partially offset by decreased average selling prices of $18.1 million.

Adjusted EBITDA

Adjusted EBITDA for the three months ended December 26, 2025 decreased by $37.3 million, or 40.4%, to $55.1 million from $92.4 million for the three months ended December 27, 2024. Adjusted EBITDA

26

margin decreased to 11.7% for the three months ended December 26, 2025 compared to 19.9% for the three months ended December 27, 2024. The decrease in Adjusted EBITDA and Adjusted EBITDA margin was largely due to lower average selling prices and higher input costs.

Adjusted EBITDA

Adjusted EBITDA increased by $14.6 million, or 93.8%, to $30.2 million for the three months ended December 26, 2025 compared to $15.6 million for the three months ended December 27, 2024. Adjusted EBITDA margin increased to 16.2% for the three months ended December 26, 2025 compared to 7.9% for the three months ended December 27, 2024. The increase in Adjusted EBITDA and Adjusted EBITDA margin was largely due to increases associated with improved operational performance and cost control in our mechanical and construction business.

LIQUIDITY AND CAPITAL RESOURCES

We believe we have sufficient liquidity to support our ongoing operations and to invest in future growth and create value for stockholders. Our cash and cash equivalents were $443.8 million as of December 26, 2025, of which $98.2 million was held at non-U.S. subsidiaries. Those cash balances at foreign subsidiaries may be subject to withholding or local country taxes if the Company’s intention to permanently reinvest such income were to change and cash was repatriated to the United States.

In general, we require cash to fund working capital investments, acquisitions, capital expenditures, debt repayment, interest payments, taxes, share repurchases and dividend payments. We have access to the ABL Credit Facility to fund operational needs. As of December 26, 2025, there were no outstanding borrowings under the ABL Credit Facility and no letters of credit issued under the ABL Credit Facility. The borrowing base was estimated to be $325.0 million and approximately $325.0 million was available under the ABL Credit Facility as of December 26, 2025. Outstanding letters of credit count as utilization of the commitments under the ABL Credit Facility and reduce the amount available for borrowings.

The agreements governing the Senior Secured Term Loan Facility and the ABL Credit Facility (collectively, the "Credit Facilities") contain covenants that limit or restrict AII’s ability to incur additional indebtedness, repurchase debt, incur liens, sell assets, make certain payments (including dividends), and enter into transactions with affiliates. AII has been in compliance with the covenants under the agreements for all periods presented.

27

We may from time to time repurchase our debt or take other steps to reduce our debt. These actions may include open market repurchases, negotiated repurchases or opportunistic refinancing of debt. The amount of debt, if any, that may be repurchased or refinanced will depend on market conditions, trading levels of our debt, our cash position, compliance with debt covenants and other considerations.

Our use of cash may fluctuate during the year and from year to year due to differences in demand and changes in economic conditions primarily related to the prices of the commodities we purchase.

Capital expenditures have historically been necessary to expand and update the production capacity and improve the productivity of our manufacturing operations.

Our ongoing liquidity needs are expected to be funded by cash on hand, net cash provided by operating activities and, as required, borrowings under the ABL Credit Facility. We expect that cash provided from operations and available capacity under the ABL Credit Facility will provide sufficient funds to operate our business, make expected capital expenditures and meet our liquidity requirements for at least the next twelve months, including payments of interest and principal on our debt.

There have been no material changes in our contractual obligations and commitments since the filing of our Annual Report on Form 10-K.

Limitations on distributions and dividends by subsidiaries

AI and AII are each holding companies, and as such have no independent operations or material assets other than ownership of equity interests in their respective subsidiaries. Each company depends on its respective subsidiaries to distribute funds to it so that it may pay obligations and expenses, including satisfying obligations with respect to indebtedness. The ability of our subsidiaries to make distributions and dividends to us depends on their operating results, cash requirements and financial and general business conditions, as well as restrictions under the laws of our subsidiaries' jurisdictions.

The agreements governing the Credit Facilities significantly restrict the ability of our subsidiaries, including AII, to pay dividends, make loans or otherwise transfer assets from AII and, in turn, to us. Further, AII's subsidiaries are permitted under the terms of the Credit Facilities to incur additional indebtedness that may restrict or prohibit the making of distributions, the payment of dividends or the making of loans by such subsidiaries to AII and, in turn, to us. The Senior Secured Term Loan Facility requires AII to meet a certain consolidated coverage ratio on an incurrence basis in connection with additional indebtedness. The ABL Credit Facility contains limits on additional indebtedness based on various conditions for incurring the additional debt. AII has been in compliance with the covenants under the agreements for all periods presented.

The table below summarizes cash flow information derived from our statements of cash flows for the periods indicated:

						Three months ended
(in thousands)						December 26, 2025						December 27, 2024
Cash flows provided by (used in):
Operating activities						$	(55,497)					$	74,374
Investing activities						6,637						(41,137)
Financing activities						(15,325)						(67,668)

Operating activities

During the three months ended December 26, 2025, the Company used $55.5 million cash flow in operating activities compared to $74.4 million provided during the three months ended December 27, 2024. The $129.9 million decrease in cash provided was primarily due to decreased operating income of $47.9 million, partially offset by less working capital used of $100.3 million and the impact of taxes of $1.9 million.

28

Investing activities

During the three months ended December 26, 2025, the Company used $6.6 million in investing activities compared to $41.1 million during the three months ended December 27, 2024. The $47.8 million decrease in cash used in investing activities was primarily due to a decrease of $29.5 million in capital expenditures and proceeds from the sale of Tectron Tube of $18.4 million.

Financing Activities

During the three months ended December 26, 2025, the Company was provided $15.3 million in financing activities compared to $67.7 million used during the three months ended December 27, 2024. The decrease in cash used in financing activities is primarily due to $50.0 million less cash used to repurchase common stock during the three months ended December 26, 2025.

CHANGES IN CRITICAL ACCOUNTING POLICIES AND ESTIMATES

There have been no material changes in our critical accounting policies and estimates since the filing of our Annual Report on Form 10-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There have been no material changes to the quantitative and qualitative disclosures about market risks previously disclosed in our Annual Report on Form 10-K.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes to our internal control over financial reporting in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) under the Exchange Act during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

For a discussion of certain litigation involving the Company, see Note 15, “Commitments and Contingencies” to our unaudited condensed consolidated financial statements.

Item 1A. Risk Factors

Other than as set forth below, there have been no material changes to the risk factors previously disclosed in our Annual Report on Form 10-K.

We are reviewing strategic alternatives and there can be no assurance that we will be successful in identifying or completing any strategic transaction, or that any such strategic transaction will result in additional value for our stockholders.

On November 20, 2025, we announced that our Board of Directors has initiated a review of strategic alternatives to maximize shareholder value, including, among other things, a potential sale or merger of the whole Company. There is no deadline or definitive timetable set for completion of the strategic alternatives review process. There can be no assurance that this process will result in us pursuing a transaction or other outcome or that we will be able to execute any strategic alternative that is identified and pursued. The process of reviewing strategic alternatives may be time consuming and disruptive to our business operations and, if we are unable to effectively manage the process, our business, financial condition and results of operations could be adversely affected. We have incurred and expect to continue to incur, substantial expenses associated with identifying, evaluating and negotiating potential strategic alternatives. There can be no assurance that any potential transaction or other strategic alternative if consummated, will provide greater value to our stockholders than that reflected in the current price of our common stock. We do not intend to make any further announcements regarding the review of strategic alternatives unless and until our Board of Directors determines further disclosure is appropriate or necessary. Accordingly, speculation regarding any developments related to the review of strategic alternatives and perceived uncertainties related to our future could cause our stock price to fluctuate significantly.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Issuer Purchases of Equity Securities

On May 2, 2024, the Company’s Board of Directors approved a new share repurchase program (the “2024 Plan”). The 2024 Plan authorizes the Company to repurchase up to $500.0 million of its outstanding stock. The 2024 Plan will be funded from the Company’s available cash balances. As of December 26, 2025, there was $328.1 million of purchases remaining under the 2024 Plan. The 2024 Plan does not obligate the Company to acquire any particular amount of common stock, and it may be terminated at any time at the Company’s discretion.

As illustrated in the following table, there were no share purchases of our common stock under the 2024 Plan during the first quarter of fiscal 2026 (in thousands, except per share data):
