Termination of Material Agreement Form 8 K

As previously disclosed, in connection with Alcoa Corporation's ("Alcoa") acquisition of Alumina Limited, pursuant to which Alumina Limited became a wholly-owned subsidiary of Alcoa, Alcoa assumed $385 million of Alumina Limited's outstanding indebtedness under its revolving credit facility (the "Facility"), governed by the Syndicated Revolving Cash Advance Facility Agreement, dated December 2, 2013, by and among Alumina Limited, as the borrower, Australia and New Zealand Banking Group Limited, as the agent, and the lenders party thereto (as amended and restated, the "Facility Agreement"). At the time of the acquisition, the Facility had tranches maturing in October 2025 ($100 million), January 2026 ($150 million), July 2026 ($150 million), and June 2027 ($100 million). In August 2024, Alcoa cancelled the undrawn lender commitments under the Facility maturing in July 2026 ($15 million) and June 2027 ($100 million).

On November 29, 2024, pursuant to the terms of the Facility Agreement, Alcoa voluntarily repaid all accrued and unpaid amounts outstanding under the Facility, totaling $385 million and, as of the same date, cancelled the outstanding lender commitments ($385 million). As a result of the repayment and cancellation of undrawn amounts, the Facility Agreement is effectively terminated. No early termination penalties or prepayment premiums were incurred by Alcoa in connection with the termination of the Facility.
