FOR IMMEDIATE RELEASE

Alcoa Corporation Announces Proposed Debt Offering

March 3, 2025—PITTSBURGH— Alcoa Corporation (NYSE:AA; ASX:AAI) (“Alcoa”) announced today a proposed offering of $1,000,000,000 aggregate principal amount of senior notes (the “notes”) by Alumina Pty Ltd (ABN 85 004 820 419) (the “Issuer”), a wholly-owned subsidiary of Alcoa. The notes will be guaranteed on a senior unsecured basis by Alcoa and certain of its subsidiaries. The timing of pricing and terms of the notes are subject to market conditions and other factors.

The Issuer intends to deploy the funds within the Alcoa group, including funding contributions to Alcoa Nederland Holding B.V. (“ANHBV”), a wholly-owned subsidiary of Alcoa and the issuer of the outstanding $750 million aggregate principal amount of 5.500% Notes due 2027 (the “Existing 2027 Notes”) and $500 million aggregate principal amount of 6.125% Notes due 2028 (the “Existing 2028 Notes”). These contributions will be funded through a series of intercompany transactions, including the repayment of intercompany indebtedness and the issuance of intercompany dividends. ANHBV intends to use any such funds, along with cash on hand, to fund the purchase price pursuant to the cash tender offers (the “Tender Offers”) also announced today for any and all of the Existing 2027 Notes and up to $250 million of the Existing 2028 Notes to the extent tendered and accepted by ANHBV for purchase in the Tender Offers and to pay related transaction fees, including applicable premiums and expenses. If there are any net proceeds remaining from the offering, including if the Tender Offers are not consummated, Alcoa intends to use such funds for general corporate purposes, which may include the redemption by ANHBV of the Existing 2027 Notes and Existing 2028 Notes. The offering is not conditioned upon the consummation of the Tender Offers.

The notes and related guarantees will be sold in a private placement to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-United States persons in offshore transactions in accordance with Regulation S under the Securities Act. The notes and related guarantees have not been and will not be registered under the Securities Act or the securities laws of any other jurisdiction and may not be offered or sold in the United States or to, or for the benefit of, U.S. persons absent registration under, or an applicable exemption from, the registration requirements of the Securities Act.

This press release does not constitute an offer to buy or sell or a solicitation of an offer to buy or sell the notes and related guarantees, the Existing 2027 Notes, the Existing 2028 Notes or any other security and there will be no offer, solicitation, purchase or sale in any state or jurisdiction in which, or to any persons to whom, such an offer, solicitation, purchase or sale would be unlawful. Any offers of the notes and related guarantees will be made only by means of a private offering memorandum. The Tender Offers are being made only by means of the relevant offer to purchase and notice of guaranteed delivery, as applicable.

Exhibit 99.2

Announcement by Alcoa Corporation of Offers to Purchase for Cash

Certain Outstanding Securities Listed Below

Pittsburgh, Pennsylvania, March 3, 2025 – Alcoa Corporation (“Alcoa”) (NYSE: AA) announces that its wholly-owned subsidiary, Alcoa Nederland Holding B.V. (“ANHBV”), has commenced the following offers to purchase:

Information on the Offers

The Any and All Offer is scheduled to expire at 5:00 p.m., New York City time, on March 14, 2025, unless extended or earlier terminated by ANHBV in its sole discretion (such time and date, as it may be extended or earlier terminated, the “Any and All Expiration Date”). Holders of Any and All Notes who validly tender (and do not validly withdraw) their Any and All Notes at or prior to the Any and All Expiration Date or deliver a properly completed and duly executed notice of guaranteed delivery at or prior 5:00 p.m., New York City time, March 18, 2025, will be eligible to receive the Any and All Total Consideration (as defined below). Validly tendered Any and All Notes may be validly withdrawn at any time at or prior to the Any and All Expiration Date, unless extended or earlier terminated by ANHBV as described in that certain offer to purchase dated March 3, 2025 relating to the Any and All Offer and the Capped Offer (the “Offer to Purchase”), but not thereafter.

The “Any and All Total Consideration” payable per US$1,000 principal amount of Any and All Notes validly tendered and not validly withdrawn and accepted for purchase pursuant to the Any and All Offer, will be determined in the manner described in the Offer to Purchase by reference to the applicable Fixed Spread for such Any and All Notes plus the applicable yield based on the bid-side price of the applicable U.S. Treasury Reference Security specified in the table above at 11:00 a.m., New York City time, on the Any and All Price Determination Date (as defined in the Offer to Purchase). If the Any and All Expiration Date is extended by more than 48 hours by ANHBV in its sole discretion, the Any and All Price Determination Date may be extended to 11:00 a.m., New York City time, on the same day as the extended Any and All Expiration Date.

The Capped Offer is scheduled to expire at 5:00 p.m., New York City time, on March 31, 2025, unless extended or earlier terminated by ANHBV in its sole discretion (such time and date, as it may be extended or earlier terminated, the “Capped Expiration Date” and, together with the Any and All Expiration Date, each an “Expiration Date”). Holders of Capped Notes who validly tender (and do not validly withdraw) their Capped Notes at or prior to 5:00 p.m., New York City time, on March 14, 2025, unless extended or earlier terminated by ANHBV in its sole discretion (such time and date, as it may be extended or earlier terminated, the “Capped Early Tender Date”) will be eligible to receive the Capped Early Consideration set forth in the table above for each US$1,000 principal amount of Capped Notes (the “Capped Early Consideration”), which includes an early tender premium (the “Early Tender Premium”). Holders of Capped Notes who validly tender their Capped Notes after the Capped Early Tender Date but at or prior to the Capped Expiration Date in the manner described in the Offer to Purchase will not be eligible to receive the Capped Early Consideration and will, therefore, only be eligible to receive the Capped Late Consideration set forth in the table above for each US$1,000 principal amount of Capped Notes (which does not include the Early Tender Premium) (the “Capped Late Consideration”). Validly tendered Capped Notes may be validly withdrawn at any time prior to the Capped Early Tender Date but not thereafter, except as the Capped Early Tender Date may extended or earlier terminated by ANHBV in its sole discretion.

In addition to the Any and All Total Consideration, the Capped Early Consideration, or the Capped Late Consideration, as applicable, all holders whose Notes are accepted for purchase pursuant to the Offers will be paid accrued and unpaid interest on the Notes (“Accrued Interest”) from, and including, the applicable last interest payment date up to, but not including, the applicable Settlement Date (as defined below) payable on such date. For the avoidance of doubt, we will not pay Accrued Interest for any periods following the applicable Settlement Date in respect of any Notes accepted for purchase in the applicable Offer. Accrued Interest on the Any and All Notes tendered using the guaranteed delivery procedures set forth in the Offer to Purchase will cease to accrue on the Any and All Settlement Date.

If the aggregate principal amount of the Capped Notes validly tendered (and not validly withdrawn) at or prior to the Capped Early Tender Date or the Capped Expiration Date exceeds the Maximum Principal Amount, a prorated amount of the Capped Notes validly tendered (and not validly withdrawn) by holders of the Capped Notes at or prior to the Capped Early Tender Date or the Capped Expiration Date, as the case may be, will be accepted for purchase.

Notes may be tendered and accepted for payment only in principal amounts equal to minimum denominations of US$200,000 and integral multiples of US$1,000 in excess thereof. Holders who tender less than all their Notes must continue to hold such series of Notes in minimum principal amounts of US$200,000 and integral multiples of US$1,000.

Subject to applicable law, each of the Offers may be individually amended, extended, terminated or withdrawn without amending, extending, terminating or withdrawing, as the case may be, the other Offer.

Settlement

Settlement of the Any and All Offer is expected to occur on the third Business Day (as defined in the Offer to Purchase) following the Any and All Expiration Date, unless the Any and All Expiration Date is extended or earlier terminated by ANHBV in its sole discretion (the “Any and All Settlement Date”). Tendered Any and All Notes may be withdrawn at any time at or prior to the Any and All Expiration Date. If the Any and All Offer is extended, the Any and All Withdrawal Date will be extended until the extended Any and All Expiration Date; provided that the Any and All Withdrawal Date will be further extended to permit withdrawal at any time after the 60th Business Day after commencement of the Any and All Offer if for any reason the Any and All Offer has not been consummated within 60 Business Days after commencement thereof.

2

Holders of the Capped Notes that have validly tendered and not validly withdrawn their Capped Notes at or prior to the Capped Early Tender Date and whose Capped Notes are accepted for purchase shall, if ANHBV so elects, receive the Capped Early Consideration on the early settlement date, which date is expected to occur three Business Days following the Capped Early Tender Date (the “Capped Early Settlement Date”). If ANHBV does not, in its sole discretion, elect to pay for such tendered Capped Notes prior to the Capped Expiration Date, then the Early Settlement Date will be the same as the final settlement date, which date is expected to occur two Business Days following the Capped Expiration Date (the “Capped Final Settlement Date” and, together with the Early Settlement Date and the Any and All Settlement Date, each a “Settlement Date”).

Conditions to Offers

ANHBV’s obligation to purchase Notes in the Offers is conditioned on the satisfaction or waiver of a number of conditions described in the Offer to Purchase, including (i) the entry by Alumina Pty Ltd (ABN 85 004 820 419) (“Alumina Pty”), a wholly-owned subsidiary of Alcoa, into a purchase agreement, on terms and conditions reasonably satisfactory to Alumina Pty, for the offer and sale of $1 billion aggregate principal amount of debt securities of one or more series to investors (the “New Notes Offering”) yielding net proceeds that will be provided to ANHBV following a series of transactions among wholly-owned entities in the Alcoa group and that are sufficient, along with cash on hand, to fund the payment of the Any and All Total Consideration, Capped Early Consideration or Capped Late Consideration, as applicable, and Accrued Interest due to holders of the relevant Notes tendered in the Offers (the “Pricing Condition”), and (ii) the closing of the New Notes Offering and receipt by ANHBV of the net proceeds therefrom on or prior to the applicable Settlement Date (the “New Notes Settlement Condition” and together with the Pricing Condition, the “Financing Condition”). There can be no assurance that Alumina Pty will complete on time, or at all, the New Notes Offering or that the Financing Condition or any other condition will be satisfied.

Neither of the Offers is conditioned upon the tender of any minimum principal amount of Notes of such series or of the other series. However, the Capped Offer is subject to the Maximum Principal Amount. ANHBV reserves the right, but is under no obligation, to increase or decrease the Maximum Principal Amount at any time without reinstating withdrawal rights or extending the Capped Early Tender Date, subject to applicable law. In the event of a termination of an Offer, neither the applicable consideration nor Accrued Interest will be paid or become payable to the holders of the applicable series of Notes, and the Notes tendered pursuant to such Offer will be promptly returned to the tendering holders. ANHBV has the right, in its sole discretion, not to accept any tenders of Notes for any reason and to amend or terminate the Offers at any time.

Subsequent Redemptions or Repurchases

From time to time after each applicable Expiration Date or termination or withdrawal of any of the Offers, ANHBV or any of its affiliates may acquire any Notes that are not purchased pursuant to the Offers through open market purchases, privately-negotiated transactions, tender offers, exchange offers, redemptions or otherwise, upon such terms and at such prices as ANHBV or any of its affiliates may determine, which may be more or less than the price to be paid pursuant to the Offers and could be for cash or other consideration. ANHBV may also exercise its right to redeem any Notes not purchased in the Offers and that remain outstanding after the applicable Expiration Date pursuant to the respective indenture governing such series of Notes. There can be no assurance as to which, if any, of these alternatives or combinations thereof ANHBV will choose to pursue in the future.
