Alcoa Corp Announces $2.6B Senior Notes Offering to Fund South32 Acquisition

What Happened
On September 23, 2026, Alcoa Corporation disclosed that two wholly owned subsidiaries completed a combined $2.6 billion senior note offering: $1.5 billion of 6.625% senior notes due 2034 (issued by Alumina Pty Ltd) and $1.1 billion of 6.875% senior notes due 2036 (issued by Alcoa Nederland Holding B.V.). The notes are senior unsecured obligations guaranteed by Alcoa and certain of its subsidiaries and were issued under indentures dated September 23, 2026, with The Bank of New York Mellon Trust Company, N.A. as trustee. The notes were sold in private placements to qualified institutional buyers (Rule 144A) and to certain non-U.S. persons offshore (Regulation S). Alcoa stated the net proceeds, together with cash on hand, will fund the roughly $3.1 billion cash portion of the previously announced proposed acquisition of certain South32 bauxite, alumina and aluminum smelter interests (Umbrella Implementation Deed dated June 30, 2026). Concurrently, Alcoa terminated remaining commitments under the 364‑day bridge term loan facility used previously in connection with the acquisition.

Key Details

• Total notes issued: $2.6 billion (2034 Notes: $1.5B at 6.625%; 2036 Notes: $1.1B at 6.875%).
• Maturities and optional redemption: 2034 Notes callable on/after Sept 30, 2029; 2036 Notes callable on/after Sept 30, 2031; make-whole and other redemption provisions apply prior to those dates.
• Equity-raise carve-out: Issuers may redeem up to 40% of notes prior to Sept 30, 2029 using net proceeds from certain equity offerings.
• Special mandatory redemption: If the Acquisition is not completed by the later of June 29, 2027 (or any extended “Conditions Precedent End Date”) or the parties’ extended date, the Issuers must redeem the notes at 100% of issue price (plus accrued interest); failure to do so would be an event of default.
• Other: Change-of-control repurchase at 101% of principal; notes governed by indentures filed as exhibits; proceeds used for acquisition consideration and related fees/expenses.

Why It Matters
This financing materially affects Alcoa’s capital structure by replacing short-term bridge financing with $2.6 billion of longer-term unsecured debt to fund a major acquisition. Investors should note the relatively high fixed coupon rates (6.625% and 6.875%) and long maturities, which increase interest obligations but reduce near-term refinancing risk compared with the terminated bridge facility. The notes include standard covenants, redemption mechanics and a special mandatory redemption tied to completion of the South32 transaction; if the acquisition fails and the mandatory redemption is required but not made, an event of default could occur. Completion of the Acquisition remains subject to shareholder approvals, regulatory consents and other customary conditions.
