DALLAS, Oct. 29, 2026 /PRNewswire/ — ATI Inc. (NYSE: ATI) reported third quarter 2026 results, with sales of $1.42 billion and net income attributable to ATI of $190 million, or $1.37 per share.

“We had a strong third quarter, exceeding the high-end of our guidance. We are raising our full-year outlook for adjusted EBITDA by $35 million. This follows the $125 million increase in our outlook just last quarter,” said Kimberly A. Fields, Board Chair, President and CEO. “Sales in the quarter grew 26% year-over-year, while adjusted EBITDA increased by 46% year-over-year. Our results reflect three main drivers: strong demand backed by long-term agreements, differentiated capabilities that make us the partner of choice, and disciplined execution across our operations.

“These results show the strength and balance of ATI’s portfolio and reinforce our growth outlook,” Fields continued. “We’re delivering on our commitments and positioning ATI for even stronger performance in 2027.”

Third quarter 2026 GAAP earnings per share were $1.37 and adjusted earnings per share^(a) were $1.46. Net income attributable to ATI was $189.8 million and ATI adjusted EBITDA^(a) was $327.9 million, or 23.0% of sales. Third quarter 2026 adjusted results exclude pre-tax charges of $15.6 million for special items consisting of $14.4 million for restructuring and other charges and a $1.2 million debt extinguishment charge. The after-tax impact of these special items was a charge of $12.1 million, or $0.09 per share.

The third quarter 2026 restructuring and other charges include $8.4 million of transformation-related costs, $2.9 million of losses on the sale of customer accounts receivable, $2.2 million of start-up and transaction-related costs, and $0.9 million of restructuring-related costs.

Operating Results by Segment

• HPMC’s third quarter 2026 sales increased $84.3 million, or 13%, compared to second quarter 2026, primarily due to strong demand and pricing for commercial jet engine products as well as demand for defense products.

• Third quarter 2026 sales increased 20% compared to third quarter 2025, primarily driven by a 34% increase in sales of commercial jet engine products due to strong demand and pricing.
• HPMC third quarter 2026 segment EBITDA^(a) was $167.3 million, or 23.2% of sales. The sequential and year-over-year decline in segment EBITDA margin was primarily due to higher manufacturing and period costs, including costs associated with ramping commercial production of a new nickel-based superalloy.

• AA&S third quarter 2026 sales increased $78.3 million, or 13%, compared to the second quarter 2026, primarily due to higher sales in the aerospace & defense and specialty energy markets.

Aerospace & defense represented 45% of total AA&S sales in the third quarter of 2026.
• Third quarter 2026 sales increased $179.7 million, or 34%, compared to third quarter 2025, primarily due to higher sales to the aerospace & defense, specialty energy, and conventional energy markets.

• AA&S third quarter 2026 segment EBITDA^(a) was $181.3 million, or 25.8% of sales. The sequential and year-over-year increase in segment EBITDA margin was primarily driven by higher pricing and volumes as well as a favorable sales mix.

ATI Inc.
Non-GAAP Financial Measures
(Unaudited, dollars in millions, except per share amounts)

The Company reports its financial results in accordance with accounting principles generally accepted in the United States of America (“GAAP”). This report includes financial performance measures that are not defined by GAAP, including Adjusted net income attributable to ATI, Adjusted EPS, Adjusted EBITDA, Segment EBITDA, Adjusted free cash flow and Managed working capital. The Company uses these non-GAAP financial measures to assist in assessing operating performance on a consistent basis across multiple reporting periods by removing the impact of special items, which can vary from period to period, that management does not believe are directly reflective of the Company’s core operations. The Company defines special items as significant non-recurring or non-operational charges or credits, restructuring and other charges/credits, gains or losses from the sale of accounts receivable, strike related costs, goodwill and long-lived asset impairments, debt extinguishment charges, pension remeasurement gains and losses, other postretirement/pension curtailment and settlement gains and losses, and gains or losses on sales of businesses.

Adjusted net income attributable to ATI and related Adjusted EPS are calculated by adjusting net income attributable to ATI for the tax-effected impact of special items. We define Adjusted EBITDA as net income, excluding net interest expense, income taxes, depreciation and amortization, and special items. Our measure of segment EBITDA, which we use to analyze the performance and results of our business segments, excludes net interest expense, income taxes, depreciation and amortization, special charges, corporate expenses, closed operations and other income (expense). Our methods of calculating Adjusted free cash flow and Managed working capital are discussed in greater detail below under the headings “Adjusted Free Cash Flow” and “Managed Working Capital,” respectively.

Management believes presenting these non-GAAP financial measures is useful to investors because it (1) provides investors with meaningful supplemental information regarding financial and operating performance by excluding certain items management believes do not directly impact the Company’s core operations, (2) permits investors to view performance using the same metrics that management uses to forecast, evaluate performance, and make operating and strategic decisions, and (3) provides additional information useful to investors on a period-to-period consistent basis that are commonly used to analyze companies’ operating performance. Management believes that consideration of these non-GAAP financial measures, together with our GAAP financial measures and the corresponding reconciliations, provides investors with additional understanding of the Company’s performance and trends that would be absent such disclosures.

Non-GAAP financial measures should be viewed in addition to, and not superior to or as an alternative for, the Company’s reported results prepared in accordance with GAAP. The following tables provide the calculation of the non-GAAP financial measures discussed in this press release:

Adjusted Free Cash Flow

Management utilizes a non-GAAP measure, Adjusted free cash flow, to assess the cash flow generation of the Company’s operations. Adjusted free cash flow is defined as the total cash provided by (used in) operating activities and investing activities as presented on the consolidated statements of cash flows, adjusted to exclude cash contributions to the Company’s U.S. qualified defined benefit pension plan. 

Management utilizes this measure to assess the cash flow generation performance of its business as it excludes cash contributions to the Company’s U.S. qualified benefit pension plan that are periodic rather than recurring. The impact of cash generated from the sale of assets and non-core businesses is included in the measure as the proceeds of such transactions are contemplated by Management in setting capital budgets to fund capital expenditures. Management believes this measure provides investors with additional meaningful insights as to the Company’s ability to generate cash in excess of operational and investing needs. Adjusted free cash flow is not intended to be a measure of free cash flow for management’s discretionary use, as it does not consider certain cash requirements such as interest, tax, or other contractually required payments. Further, adjusted free cash flow should be viewed in addition to, and not superior to or as an alternative for, the Company’s reported results prepared in accordance with GAAP.

Managed Working Capital

As part of managing the performance of our business, we focus on Managed working capital, a non-GAAP financial measure that we define as gross accounts receivable, short-term contract assets and gross inventories, excluding the effects of reserves for uncollectible accounts receivable and inventory valuation reserves, less accounts payable and short-term contract liabilities. We assess Managed working capital performance as a percentage of the prior three months’ annualized sales. Managed working capital is not intended to replace working capital or other GAAP financial measures or to be used as a measure of liquidity.

Management believes this non-GAAP financial measure focuses on the assets and liabilities most closely attributable to our core operations, allowing Management to quantify and evaluate the asset intensity of our business. Further, Management believes this non-GAAP financial measure provides investors with additional insights into the Company’s effectiveness in balancing the need to maintain appropriate asset levels to support sales growth and operations while deploying our cash effectively.
