On February 27, 2023, Howmet Aerospace Inc. (“Howmet” or the “Company”) issued a notice of partial redemption to redeem on March 29, 2023 (the “Redemption Date”) $150,000,000 aggregate principal amount of its outstanding 5.125% Notes due 2024 (CUSIP No. 013817AW1) (the “2024 Notes”) in accordance with the terms of the 2024 Notes and the Indenture dated as of September 30, 1993, as supplemented, between Howmet and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Indenture”). As of February 27, 2023, the aggregate outstanding principal amount of the 2024 Notes is $1,055,273,000.

The redemption price (the “Redemption Price”) for the 2024 Notes to be redeemed shall be equal to the greater of (i) 100% of the principal amount of the 2024 Notes to be redeemed, plus accrued interest, if any, to the Redemption Date or (ii) the sum of the present values of the Remaining Scheduled Payments, discounted on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 40 basis points, plus accrued interest to the Redemption Date which has not been paid. The Company expects the Redemption Price for the 2024 Notes to be redeemed to be approximately $154 million, which the Company intends to pay with cash on hand.

Capitalized terms used and not otherwise defined herein shall have the same meaning as given in the Indenture or the 2024 Notes, as the case may be.
