"Atkore achieved Net Sales of $2.9 billion in fiscal 2025 and grew organic volume for the third consecutive year," said Bill Watlz, Atkore President and Chief Executive Officer. "We returned cash to shareholders by deploying $144 million towards share repurchases and dividend payments.

Waltz continued, "Earlier today we announced that the Board of Directors has expanded the scope of its previously announced review of strategic alternatives which is intended to maximize shareholder value. I have decided to stay in my role as Atkore's President and CEO at least through the conclusion of the strategic review. Our product portfolio is well positioned to serve our customers with anticipated near-term market demand growth in several key electrical end markets, and the long-term demand outlook for electricity."

Net sales for the fourth quarter of 2025 decreased to $752.0 million, a decrease of 4.6% compared to $788.3 million for the prior-year period. The decrease was primarily due to lower average selling prices of $53.6 million as the result of expected pricing normalization. These decreases were partially offset by higher sales volume of $10.7 million and a decrease in the economic value of solar tax credits to be transferred to certain customers of $7.7 million.

Gross profit decreased by $68.2 million to $147.8 million for the fourth quarter of 2025, as compared to $216.1 million for the prior-year period. Gross margins decreased from 27.4% in the prior year period to 19.7%. Gross profit and gross profit margin decreased primarily due to declines in average selling prices of $53.6 million and higher raw material costs of $12.3 million.

Net income decreased $127.5 million to a net loss of $54.4 million for the fourth quarter of 2025, as compared to $73.1 million of net income for the prior-year period, due to lower operating income of $158.8 million, partially offset by decreased income taxes of $30.1 million. Adjusted net income decreased $63.3 million to $23.3 million compared to $86.6 million for the prior-year period.

Adjusted EBITDA decreased $69.2 million, or 49.4%, to $70.9 million for the fourth quarter of 2025, as compared to $140.1 million for the prior-year period. Net income margin decreased from 9.3% in the prior-year period to (7.2)% and Adjusted EBITDA Margin decreased 840 basis points from 17.8% to 9.4%.

Net loss per diluted share was $(1.62) for the fourth quarter of 2025, a decrease of $3.64 from the prior-year period. Adjusted net income per diluted share was $0.69 per share for the fourth quarter of 2025 compared to $2.43 for the prior-year period.

**Segment Results**

**Electrical**

Electrical net sales decreased $45.7 million, or 8.1%, to $518.9 million for the fourth quarter of 2025, as compared to $564.5 million for the prior-year period. The decrease in net sales is primarily attributed to decreased average selling prices of $51.8 million as a result of expected pricing normalization and divestitures of $3.1 million, partially offset by increased volume of $6.5 million.

Adjusted EBITDA decreased $79.7 million, or 54.7%, to $65.9 million for the fourth quarter of 2025, as compared to $145.7 million for the prior-year period, and Adjusted EBITDA Margin decreased from 25.8% to 12.7%. The decrease in Adjusted EBITDA was largely due to lower average selling prices and higher input costs.

**Safety & Infrastructure**

Safety & Infrastructure net sales increased $8.9 million, or 4.0%, to $233.4 million for the fourth quarter of 2025, as compared to $224.5 million for the prior-year period. The increase is attributed to higher volumes of $4.2 million and a decrease in the economic value of solar tax credits to be transferred to certain customers of $7.7 million, partially offset by lower average selling prices of $1.8 million.

Adjusted EBITDA increased $11.9 million, or 80.0%, to $26.8 million for the fourth quarter of 2025, as compared to $14.9 million for the prior-year period. Adjusted EBITDA Margin increased from 6.6% to 11.5%. The increase in Adjusted EBITDA and Adjusted EBITDA Margin was primarily driven by lower input costs.

**Fiscal 2025 Full-Year Results**

Net sales for fiscal 2025 decreased $351.7 million to $2,850.4 million, a decrease of 11.0% compared to $3,202.1 million for fiscal 2024. The decrease in net sales is primarily attributed to decreased average selling prices of $381.8 million and divestitures of $9.3 million. These decreases are partially offset by increased sales volume of $21.6 million across varying product categories within both the Electrical and the Safety & Infrastructure segments and a decrease in the economic value of solar tax credits to be transferred to certain customers of $15.7 million.

Gross profit for fiscal 2025 decreased $401.7 million to $676.1 million, a decrease of 37.3% compared to $1,077.8 million for fiscal 2024. Gross margin decreased to 23.7% in fiscal 2025 compared to 33.7% in fiscal 2024 due to declines in average selling prices of $381.8 million and a decrease in the net benefit of solar tax credits of $9.9 million.

Net income decreased $488.0 million to a net loss of $15.2 million for fiscal 2025, as compared to net income of $472.9 million for fiscal 2024. Adjusted net income decreased $327.1 million to $205.8 million for fiscal 2025 compared to $532.9 million for fiscal 2024. The decrease in both net income and adjusted net income was primarily driven by lower operating income of $601.6 million, partially offset by lower income tax of $117.8 million.

Adjusted EBITDA decreased $385.3 million or 49.9%, to $386.4 million for fiscal 2025, as compared to $771.7 million for fiscal 2024. The decrease was primarily due to lower operating income.

Net income per diluted share on a GAAP basis was $(0.45) for fiscal 2025, a decrease of $13.14 from fiscal 2024. Adjusted net income per diluted share was $6.05 for fiscal 2025 compared to $14.48 for fiscal 2024.

&nbsp;&nbsp;&nbsp;&nbsp;

**Liquidity & Capital Resources**

During fiscal 2025, operating activities provided $402.8 million of cash, compared to $549.0 million during fiscal year 2024. Free cash flow decreased to $295.7 million for fiscal 2025 from $399.2 million in fiscal year 2024. The decrease in free cash flow during fiscal 2025 was driven primarily by lower operating income of $601.6 million, partially offset by non-cash asset impairments of $214.4 million, less cash used in working capital of $123.1 million, tax impacts of $105.5 million, decreased capital expenditures of $42.8 million, higher depreciation and amortization of $8.6 million and a non-cash loss on sale of a business of $6.2 million.

During fiscal 2025, the Company repurchased $100.0 million of its outstanding stock, leaving $328.1 million of authorization remaining on the current plan.

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.

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, 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 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
