Summary
Alcoa completed a $2.6 billion senior notes offering through two wholly-owned subsidiaries to fund the cash portion of its proposed acquisition of South32's bauxite, alumina, and aluminum smelter interests. The offering consists of $1.5 billion of 6.625% notes due 2034 and $1.1 billion of 6.875% notes due 2036, both guaranteed on a senior unsecured basis by Alcoa and certain subsidiaries.
The proceeds, together with cash on hand, will cover the approximately $3.1 billion cash consideration for the acquisition, which remains subject to South32 shareholder approval, regulatory approvals, and other customary closing conditions.
The notes include a special mandatory redemption feature: if the acquisition is not completed by June 29, 2027, or the deal is terminated earlier, Alcoa must redeem both note series at 100% of principal plus accrued interest. This protects noteholders if the acquisition falls through. The notes also carry a standard change-of-control provision requiring an offer to repurchase at 101% of principal plus accrued interest. Concurrently with the notes offering, Alcoa terminated all remaining commitments under its 364-day bridge term loan credit facility, replacing that interim financing with the completed notes offering. For retail holders, this filing confirms Alcoa has secured the debt financing needed for the South32 acquisition, but the deal itself is not yet closed. The special mandatory redemption feature provides downside protection for noteholders if the acquisition fails to complete.
