ATI Announces Proposed Senior Notes Offering

DALLAS, TX — (PR Newswire)—June 3, 2026 — ATI Inc. (NYSE: ATI) announced today its intention to offer, subject to market

and other conditions, a series of seven-year senior notes (the “Notes”).

ATI intends to use the net proceeds of the offering of the Notes to

redeem all of its outstanding 5.875% Senior Notes due 2027 (the “2027 Notes”). Any net proceeds that are not used to fund this redemption will be used for general corporate purposes. This news release is not a notice of redemption with

respect to the 2027 Notes.

Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC are acting as the joint book-running managers and co-global

coordinators for the offering.

The offering of the Notes is being made pursuant to an effective shelf registration statement. The offering will be made

only by means of a prospectus supplement and the accompanying prospectus. Copies of the preliminary prospectus supplement and the accompanying prospectus may be obtained from Goldman Sachs & Co. LLC, Attention: Registration Department, 200

West Street, New York, NY 10282, telephone: (866) 471-2526, or by emailing registration-syndops@ny.email.gs.com or from the Securities and Exchange Commission’s website at

www.sec.gov.

This news release shall not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any sale of the Notes in

any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

***********

This news release contains “forward-looking statements” within the meaning of the Private

Securities Litigation Reform Act of 1995. Certain statements in this news release relate to future events and expectations and, as such, constitute forward-looking statements. Forward-looking statements, which may contain such words as

“anticipates,” “believes,” “estimates,” “expects,” “would,” “should,” “will,” “will likely result,” “forecast,” “outlook,”

“projects,” and similar expressions, are based on management’s current expectations and include known and unknown risks, uncertainties and other factors, many of which we are unable to predict or control. Our performance or

achievements may differ materially from those expressed or implied in any forward-looking statements due to the following factors, among others: (a) material adverse changes in economic or industry conditions generally, including global supply

and demand conditions and prices for our specialty materials; (b) material adverse changes in the markets we serve; (c) our inability to achieve the level of cost savings, productivity improvements, synergies, growth or other benefits

anticipated by management from strategic investments and the integration of acquired businesses; (d) volatility in the price and availability of the raw materials that are critical to the manufacture of our products; (e) declines in the

value of our defined benefit pension plan assets or unfavorable changes in laws or regulations that govern pension plan funding; (f) labor disputes or work stoppages; (g) equipment outages; (h) business and economic disruptions

associated with extraordinary events beyond our control, such as war, terrorism, international conflicts, public health issues, such as epidemics or pandemics, natural disasters and climate-related events that may arise in the future; and

(i) other risk factors summarized in our Annual Report on Form 10-K for the year ended December 28, 2025, and in other reports filed with the Securities and Exchange Commission. We assume no duty to

update our forward-looking statements.
