**ATI Announces Multi-Year $500 Million Share Repurchase Program** 

DALLAS, TX—February 19, 2026—ATI Inc. (NYSE: ATI) announced that its Board of Directors has authorized the additional repurchase of up to $500 million of its outstanding common stock, which the Company currently expects will support a multi-year share repurchase program in combination with the currently remaining $120 million from its prior authorization.

Open market repurchases will be structured to occur within the pricing and volume requirements of SEC Rule 10b-18. The stock repurchase program does not obligate the Company to repurchase any specific number of shares, and it may be modified, suspended, or terminated at any time by the Board of Directors without prior notice.
