HARVEY, IL. — May 5, 2026 (BUSINESS WIRE) - Atkore Inc. (the “Company” or “Atkore”) (NYSE: ATKR) announced earnings for its fiscal 2026 second quarter ended March 27, 2026.

“We were pleased with our second quarter results. We delivered approximately 5% year-over-year organic volume growth and solid productivity gains. In addition our net sales, Adjusted EBITDA and Adjusted EPS all improved sequentially versus our first quarter results,” said Bill Waltz, Atkore President and Chief Executive Officer. “These operating results reflect improvements from our own internal initiatives as well as benefits from solid end-market demand.”

Waltz continued, “Over the past few months, we have also completed several actions related to our broader review of strategic alternatives. We have now finalized the three plant closures previously announced, and we have recently divested both our High-Density Polyethylene Pipe & Conduit (“HDPE”) business as well as our surface protection and powder coatings business in Belgium. Each of these completed actions represent our commitment to support the electrical infrastructure market which we believe will enable long-term shareholder value creation.”

Exhibit 99.1

Net sales increased by $29.7 million, or 4.2%, to $731.4 million for the three months ended March 27, 2026, compared to $701.7 million for the three months ended March 28, 2025. The increase in net sales is primarily attributed to increased sales volume of $32.3 million, increased average selling prices of $10.2 million and foreign exchange benefits of $8.2 million partially offset by the impact of divestitures of $12.6 million.

Gross profit decreased by $49.0 million, or 26.5%, to $136.1 million for the three months ended March 27, 2026, as compared to $185.1 million for the prior-year period. Gross margin decreased to 18.6% for the three months ended March 27, 2026, as compared to 26.4% for the prior-year period. Gross profit decreased primarily due to increased input costs of $82.1 million outpacing increases in average selling prices of $10.2 million.

Net loss decreased by $74.0 million, or 147.9%, to a net loss of $124.1 million for the three months ended March 27, 2026 compared to $50.1 million of net loss for the prior-year period. The decrease was primarily due to lower gross profit of $49.0 million, increased litigation settlement expense of $136.5 million, increased other expense related to loss on assets held for sale of $19.2 million and increased selling, general and administrative expense of $8.9 million, partially offset by decreased asset impairment charges of $116.2 million and increased income tax benefit of $18.2 million.

Adjusted EBITDA decreased by $35.4 million, or 30.4%, to $81.1 million for the three months ended March 27, 2026 compared to $116.4 million for the three months ended March 28, 2025. The decrease was primarily due to lower gross profit.

Net loss per diluted share prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) was $(3.65) for the three months ended March 27, 2026, as compared to $(1.46) in the prior-year period. The decrease in diluted earnings per share is primarily due to the impact of lower gross margin, litigation settlement expense and losses on assets held for sale. Adjusted net income per diluted share decreased by $0.81 to $1.23 for the three months ended March 27, 2026, as compared to $2.04 in the prior year period.

Segment Results

Electrical

Net sales increased by $39.8 million, or 8.1%, to $532.5 million for the three months ended March 27, 2026 compared to $492.7 million for the three months ended March 28, 2025. The increase in net sales is primarily attributed to increased sales volume of $28.4 million, foreign exchange benefits of $8.0 million and increased average selling prices of $6.5 million.

Adjusted EBITDA for the three months ended March 27, 2026 decreased by $16.6 million, or 18.2%, to $74.4 million from $90.9 million for the three months ended March 28, 2025. Adjusted EBITDA margin decreased to 14.0% for the three months ended March 27, 2026 compared to 18.5% for the three months ended March 28, 2025. The decrease in Adjusted EBITDA and Adjusted EBITDA margin was largely due to increases in input costs outpacing increases in average selling prices.

Safety & Infrastructure

Net sales decreased by $10.2 million, or 4.9%, for the three months ended March 27, 2026 to $199.1 million compared to $209.3 million for the three months ended March 28, 2025. The decrease is primarily attributed to the impact of recent divestitures of $9.5 million and higher solar credit rebates of $8.5 million, partially offset by increased sales volume of $3.9 million and an increase in average selling prices of $3.7 million.

Adjusted EBITDA decreased by $18.8 million, or 52.0%, to $17.3 million for the three months ended March 27, 2026 compared to $36.1 million for the three months ended March 28, 2025. Adjusted EBITDA margin decreased to 8.7% for the three months ended March 27, 2026 compared to 17.2% for the three

Exhibit 99.1

months ended March 28, 2025. The decrease in Adjusted EBITDA and Adjusted EBITDA margin was largely due to higher input costs.

Divestitures

On April 8, 2026, Atkore completed the sale of its HDPE business to Infra Pipes. Under the terms of the sales agreement, Atkore contributed its HDPE business and retained a 10% equity stake in the combined entity. In addition to contributing the HDPE business, Atkore will capitalize the combined business with approximately $28 million in cash over time.

On April 30, 2026, the Company completed the sale of its Vergo Coating SRL and Vergo Galva NV businesses in Belgium.

Legal Settlements

On April 28, 2026, the Company entered into settlement agreements (the "Settlement Agreements") with two of the three putative classes in a case captioned In re PVC Pipe Antitrust Litigation (“Class Action Litigation”). These two classes were the Direct Purchaser Plaintiffs ("DPP Plaintiffs") and the Non-Converter Seller Purchaser Plaintiffs ("NCSP" Plaintiffs) (together, the "DPP and NCSP Plaintiffs"), individually and on behalf of the putative DPP and NCSP Plaintiff class members. The Settlement Agreements totaled $136.5 million and was recognized in the Company’s financial statements for the quarter ended March 27, 2026.

Liquidity & Capital Resources

On April 30, 2026, Atkore’s Board of Directors approved a quarterly dividend payment of $0.33 per share of common stock payable on May 29, 2026 to stockholders of record on May 19, 2026.

Full-Year Outlook1

The Company is maintaining its estimated range for fiscal year 2026 Adjusted EBITDA at $340 to $360 million, and Adjusted net income per diluted share at $5.05 to $5.55.

The Company notes that this perspective may vary due to changes in assumptions or market conditions and other factors described under “Forward-Looking Statements.”

Forward-looking statements are subject to known and unknown risks and uncertainties, many of which may be beyond our control. We caution you that forward-looking statements are not guarantees of future performance or outcomes and that actual performance and outcomes, including, without limitation, our actual results of operations, financial condition and liquidity, and the development of the market in which we operate, may differ materially from those made in or suggested by the forward-looking statements contained in this press release. In addition, even if our results of operations, financial condition and cash flows, and the development of the market in which we operate, are consistent with the forward-looking statements contained in this press release, those results or developments may not be indicative of results or developments in subsequent periods.

Additional factors that could cause actual results and outcomes to differ from those reflected in forward-looking statements include, without limitation: declines in, and uncertainty regarding, the general business and economic conditions in the United States and international markets in which we operate; weakness or another downturn in the United States non-residential construction industry; changes in prices of raw materials; pricing pressure, reduced profitability, or loss of market share due to intense competition; availability and cost of third-party freight carriers and energy; high levels of imports of products similar to those manufactured by us; changes in federal, state, local and international governmental regulations and trade policies, including application of tariffs; adverse weather conditions; increased costs relating to future capital and operating expenditures to maintain compliance with environmental, health and safety laws; reduced spending by, deterioration in the

Exhibit 99.1

financial condition of, or other adverse developments, including inability or unwillingness to pay our invoices on time, with respect to one or more of our top customers; increases in our working capital needs, which are substantial and fluctuate based on economic activity and the market prices for our main raw materials, including as a result of failure to collect, or delays in the collection of, cash from the sale of manufactured products; work stoppage or other interruptions of production at our facilities as a result of disputes under existing collective bargaining agreements with labor unions or in connection with negotiations of new collective bargaining agreements, as a result of supplier financial distress, or for other reasons; widespread outbreak of diseases; changes in our financial obligations relating to pension plans that we maintain in the United States; reduced production or distribution capacity due to interruptions in the operations of our facilities or those of our key suppliers; loss of a substantial number of our third-party agents or distributors or a dramatic deviation from the amount of sales they generate; security threats, attacks, or other disruptions to our information systems, or failure to comply with complex network security, data privacy and other legal obligations or the failure to protect sensitive information; possible impairment of goodwill or other long-lived assets as a result of future triggering events, such as declines in our cash flow projections or customer demand and changes in our business and valuation assumptions; safety and labor risks associated with the manufacture and in the testing of our products; product liability, construction defect and warranty claims and litigation relating to our various products, as well as government inquiries and investigations, and consumer, employment, tort and other legal proceedings; our ability to protect our intellectual property and other material proprietary rights; risks inherent in doing business internationally; changes in foreign laws and legal systems; our inability to introduce new products effectively or implement our innovation strategies; our inability to continue importing raw materials, component parts and/or finished goods; the incurrence of liabilities and the issuance of additional debt or equity in connection with acquisitions, joint ventures or divestitures and the failure of indemnification provisions in our acquisition agreements to fully protect us from unexpected liabilities; failure to manage acquisitions successfully, including identifying, evaluating, and valuing acquisition targets and integrating acquired companies, businesses or assets; the incurrence of additional expenses, increases in the complexity of our supply chain and potential damage to our reputation with customers resulting from regulations related to “conflict minerals”; disruptions or impediments to the receipt of sufficient raw materials resulting from various anti-terrorism security measures; restrictions contained in our debt agreements; failure to generate cash sufficient to pay the principal of, interest on, or other amounts due on our debt; failure to generate cash sufficient to pay dividends; challenges attracting and retaining key personnel or high-quality employees; future changes to tax legislation; failure to generate sufficient cash flow from operations or to raise sufficient funds in the capital markets to satisfy existing obligations and support the development of our business; and other risks and factors described from time to time in documents that we file with the SEC. The Company assumes no obligation to update the information contained herein, which speaks only as of the date hereof.

Non-GAAP Financial Information

This press release includes certain financial information, not prepared in accordance with Generally Accepted Accounting Principles in the United States (“GAAP”). Because not all companies calculate non-GAAP financial information identically (or at all), the presentations herein may not be comparable to other similarly titled measures used by other companies. Further, these measures should not be considered substitutes for the performance measures derived in accordance with GAAP. See non-GAAP reconciliations below in this press release for a reconciliation of these measures to the most directly comparable GAAP financial measures.

Adjusted EBITDA and Adjusted EBITDA Margin

We use Adjusted EBITDA and Adjusted EBITDA margin in evaluating the performance of our business and in the preparation of our annual operating budgets as indicators of business performance and profitability. We believe Adjusted EBITDA and Adjusted EBITDA margin allow us to readily view operating trends, perform analytical comparisons and identify strategies to improve operating performance.

Exhibit 99.1

We define Adjusted EBITDA as net 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, impairment of assets, certain legal matters, and other items, such as inventory reserves and adjustments, 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 Adjusted EBITDA margin as Adjusted EBITDA as a percentage of Net sales.

We believe Adjusted EBITDA and Adjusted EBITDA margin, when presented in conjunction with comparable GAAP measures, are useful for investors because management uses Adjusted EBITDA and Adjusted EBITDA margin in evaluating the performance of our business.

Adjusted Net Income and Adjusted Net Income per Share

We use Adjusted net income and Adjusted net income per share in evaluating the performance of our business and profitability. Management believes that these measures provide useful information to investors by offering additional ways of viewing the Company’s results that, when reconciled to the corresponding GAAP measure provide an indication of performance and profitability excluding the impact of unusual and certain non-cash items. We define Adjusted net income as net income before stock-based compensation, loss on extinguishment of debt, loss on assets held for sale, gains and losses on the divestiture of a business (including any additional tax adjustments related to those divestitures), insurance recoveries, asset impairment charges, intangible asset amortization, certain legal matters and other items, restructuring costs, accelerated depreciation, transaction costs, and the income tax expense or benefit on the foregoing adjustments that are subject to income tax. We define Adjusted net income per share as basic and diluted net income per share excluding the per share impact of stock-based compensation, intangible asset amortization, certain legal matters and other items, and the income tax expense or benefit on the foregoing adjustments that are subject to income tax.

Free Cash Flow

We define Free Cash Flow as net cash provided by (used in) operating activities, less capital expenditures. We believe that Free Cash Flow provides meaningful information regarding the Company’s liquidity.

2© Atkore This presentation is provided for general informational purposes only and it does not include every item which may be of interest, nor does it purport to present full and fair disclosure with respect to Atkore Inc. (the “Company” or “Atkore”) or its operational and financial information. Atkore expressly disclaims any current intention to update any forward-looking statements contained in this presentation as a result of new information or future events or developments or otherwise, except as required by federal securities laws. This presentation is not a prospectus and is not an offer to sell securities. This presentation contains forward-looking statements that are subject to known and unknown risks and uncertainties, many of which are beyond our control. All statements other than statements of historical fact included in this presentation are forward-looking statements. Forward-looking statements appearing throughout this presentation include, without limitation, statements regarding our intentions, beliefs, assumptions or current expectations concerning, among other things, financial position; results of operations; cash flows; prospects; growth strategies or expectations; customer retention; the outcome (by judgment or settlement) and costs of legal, administrative or regulatory proceedings, investigations or inspections, including, without limitation, collective, representative or any other litigation; and the impact of prevailing economic conditions. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “believes,” “expects,” “may,” “will,” “shall,” “should,” “would,” “could,” “seeks,” “aims,” “projects,” “is optimistic,” “intends,” “plans,” “estimates,” “anticipates” and other comparable terms. We caution you that forward-looking statements are not guarantees of future performance or outcomes and that actual performance and outcomes, including, without limitation, our actual results of operations, financial condition and liquidity, and the development of the market in which we operate, may differ materially from those made in or suggested by the forward-looking statements contained in this presentation. In addition, even if our results of operations, financial condition and cash flows, and the development of the market in which we operate, are consistent with the forward-looking statements contained in this presentation, those results or developments may not be indicative of results or developments in subsequent periods. A number of important factors, including, without limitation, the risks and uncertainties disclosed in the Company’s filings with the U.S. Securities and Exchange Commission, including but not limited to the Company’s most recent Annual Report on Form 10-K and reports on Form 10-Q and Form 8-K could cause actual results and outcomes to differ materially from those reflected in the forward-looking statements. Because of these risks, we caution that you should not place undue reliance on any of our forward-looking statements. New risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect us. Further, any forward-looking statement speaks only as of the date on which it is made. We undertake no obligation to revise the forward-looking statements in this presentation after the date of this presentation. Market data and industry information used throughout this presentation are based on management’s knowledge of the industry and the good faith estimates of management. We also relied, to the extent available, upon management’s review of independent industry surveys, forecasts and publications and other publicly available information prepared by a number of third-party sources. All of the market data and industry information used in this presentation involves a number of assumptions and limitations which we believe to be reasonable, but you are cautioned not to give undue weight to such estimates. Although we believe that these sources are reliable, we cannot guarantee the accuracy or completeness of this information, and we have not independently verified this information. While we believe the estimated market position, market opportunity and market size information included in this presentation are generally reliable, such information, which is derived in part from management’s estimates and beliefs, is inherently uncertain and imprecise. Projections, assumptions and estimates of our future performance and the future performance of the industry in which we operate are subject to a high degree of uncertainty and risk due to a variety of factors, including those described above. These and other factors could cause results to differ materially from those expressed in our estimates and beliefs and in the estimates prepared by independent parties. This presentation should be read along with the historical financial statements of Atkore, including the most recent audited financial statements. Historical results may not be indicative of future results. We use non-GAAP financial measures to help us describe our operating and financial performance. These measures may include Adjusted EBITDA, Adjusted EBITDA margin (Adjusted EBITDA over Net sales), Net debt (total debt less cash and cash equivalents), Adjusted Net Income Per Diluted Share (also referred to as “Adjusted Diluted EPS”), Leverage ratio (net debt or total debt less cash and cash equivalents, over Adjusted EBITDA on trailing twelve month (“TTM”) basis), Free Cash Flow (net cash provided by operating activities less capital expenditures) and Return on Capital to help us describe our operating and financial performance. These non-GAAP financial measures are commonly used in our industry and have certain limitations and should not be construed as alternatives to net income, total debt, net cash provided by operating activities, return on assets, and other income data measures as determined in accordance with generally accepted accounting principles in the United States, or GAAP, or as better indicators of operating performance. These non-GAAP financial measures as defined by us may not be comparable to similarly-titled non-GAAP measures presented by other companies. Our presentation of such non-GAAP financial measures should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. See the appendix to this presentation for a reconciliation of the non-GAAP financial measures presented herein to the most comparable financial measures as determined in accordance with GAAP. Fiscal Periods - The Company has a fiscal year that ends on September 30th. It is the Company's practice to establish quarterly closings using a 4-5-4 calendar. The Company's fiscal quarters typically end on the last Friday in December, March and June. Cautionary Statements
