Periodically, the Company’s Board of Directors authorizes the repurchase of ATI common stock (the “Share Repurchase Program”), most recently authorizing the repurchase of up to an additional $500 million, as announced in February 2026. Repurchases under these programs are made in the open market or in privately negotiated transactions, with the amount and timing of repurchases depending on market conditions and corporate needs. Open market repurchases are structured to occur within the pricing and volume requirements of SEC Rule 10b-18. In the quarter ended March 29, 2026, ATI used $75.0 million to repurchase 0.5 million of its common stock under the Share Repurchase Program. At March 29, 2026, the Company has utilized $655 million of the $700 million currently authorized under its previous Share Repurchase Program, announced in September 2024. As of March 29, 2026, total share repurchase authorization remaining under the Company's active Share Repurchase Programs was $545 million. In the quarter period ended March 30, 2025, ATI used $70.0 million to repurchase 1.2 million of its common stock under the Share Repurchase Program.

The Company’s share repurchases are subject to a 1% excise tax due to the Inflation Reduction Act of 2022. Excise taxes incurred on share repurchases represent direct costs of the repurchase and are recorded as part of the cost basis of the shares within treasury stock.
