Atkore Inc. 10-K

Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures Our President and CEO, William E. Waltz, and our Vice President and CFO, John M. Deitzer, have evaluated our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act) as of the end of the period covered by this Annual Report on Form 10-K as required by Rule 13a-15(b) and Rule 15d-15(b) under the Exchange Act. Messrs. Waltz and Deitzer have concluded that both the design and operation of our disclosure controls and procedures were effective as of September 30, 2025. Changes in Internal Control over Financial Reporting No changes in the Company’s internal control over financial reporting, as defined in Rule 13a-15(f) or Rule 15d-15(f) under the Exchange Act, occurred during the fourth quarter of fiscal 2025 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting. Management’s Report on Internal Control over Financial Reporting The Company’s management is responsible for establishing and maintaining adequate internal controls over financial reporting. The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. The Company’s management assessed, under the supervision and with the participation of our President and CEO, William E. Waltz, and our Vice President and CFO, John M. Deitzer, the effectiveness of the Company’s internal control over financial reporting as of September 30, 2025. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013). Based on this assessment, management concluded that, as of September 30, 2025, the Company’s internal control over financial reporting is effective based on those criteria. The Company’s independent registered public accounting firm, Deloitte & Touche LLP, has issued an audit report on the Company’s internal control over financial reporting for fiscal 2025. 101 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the shareholders and the Board of Directors of Atkore Inc. Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of Atkore Inc. and subsidiaries (the “Company”) as of September 30, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 30, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended September 30, 2025, of the Company and our report dated November 25, 2025, expressed an unqualified opinion on those financial statements. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. 102 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ DELOITTE & TOUCHE LLP Chicago, Illinois November 25, 2025 103 Item 9B.

(PARENT) CONDENSED FINANCIAL INFORMATION NOTES TO CONDENSED FINANCIAL INFORMATION (dollars in thousands) 1. Description of Atkore Inc. Atkore Inc. (the “Company,” “Parent” or “Atkore”) was incorporated in the State of Delaware on November 4, 2010 under the name Atkore International Group Inc. The Company was the stockholder of Atkore International Holdings Inc. (“AIH”), which was the sole stockholder of Atkore International Inc. (“AII”). On December 31, 2022, AIH merged into AII, with AII being the surviving entity. Accordingly, Atkore is now the sole stakeholder of AII. Prior to the transactions described below, all of the capital stock of AII was owned by Tyco International Ltd. (“Tyco”). The business of AII was operated as the Tyco Electrical and Metal Products (“TEMP”) business of Tyco. Atkore was initially formed by Tyco as a holding company to hold ownership of TEMP. On November 9, 2010, Tyco announced that it had entered into an agreement to sell a majority interest in TEMP to CD&R Allied Holdings, L.P. (the “CD&R Investor”), an affiliate of the private equity firm Clayton Dubilier & Rice, LLC (“CD&R”). On December 22, 2010, the transaction was completed and CD&R acquired shares of a newly created class of cumulative convertible preferred stock (the “Preferred Stock”) of the Company. The Preferred Stock initially represented 51 % of the Company's outstanding capital stock (on an as-converted basis). On December 22, 2010, the Company also issued common stock (the “Common Stock”) to Tyco's wholly owned subsidiary, Tyco International Holding S.à.r.l. (“Tyco Seller”), that initially represented the remaining 49 % of the Company's outstanding capital stock. Subsequent to December 22, 2010, the Company has operated as an independent, stand-alone entity. On March 6, 2014, the Company entered into a non-binding letter of intent (the “Letter of Intent”) with Tyco for the acquisition (the “Acquisition”) of 40.3 million shares of Common Stock held by Tyco Seller. On April 9, 2014, the Company paid $ 250,000 to Tyco Seller to redeem the shares, which were subsequently retired. The Company paid $ 2,000 of expenses related to the share redemption. In a separate transaction on the same date, the CD&R Investor converted its Preferred Stock and accumulated Preferred Dividends into Common Stock. As a result, Common Stock is the Company's sole issued and outstanding class of securities. The Parent has no significant operations or assets other than its indirect ownership of the equity of AII. Accordingly, the Parent is dependent upon distributions from AII to fund its obligations. However, under the terms of the agreements governing AII's borrowings, AII's ability to pay dividends or lend to Atkore Holding or the Parent, is restricted. While certain exceptions to the paying dividends or lending funds restrictions exist, these restrictions have resulted in the restricted net assets (as defined in Rule 4-08(e)(3) of Regulation S-X) of the Company's subsidiaries exceeding 25% of the consolidated net assets of the Company and its subsidiaries. Atkore Holding has no obligations to pay dividends to the Parent except to pay specified amounts to Parent in order to fund the payment of the Parent's tax obligations. 2. Basis of Presentation The accompanying condensed Parent only financial statements are required in accordance with Rule 4-08(e)(3) of Regulation S-X. The financial statements include the amounts of the Parent and its investment in its subsidiaries under the equity method and does not present the financial statements of the Parent and its subsidiaries on a consolidated basis. Under the equity method, investment in its subsidiaries is stated at cost plus contributions and equity in undistributed income (loss) of subsidiary less distributions received since the date of acquisition. These condensed Parent only financial statements should be read in conjunction with the Atkore Inc. consolidated financial statements and their accompanying notes. 115 3.
