Alcoa to buy South32's bauxite, alumina and smelter stakes for $3.1 billion cash
On June 30, 2026, Alcoa agreed to acquire South32's interests in bauxite mine, alumina refinery and aluminum smelter operations for $3.1 billion in cash plus about 17 million Alcoa shares, with an agreed value of about $1 billion, plus a contingent payment of up to $750 million. The deal is expected to close in the first half of 2027, subject to South32 shareholder and regulatory approvals, and Alcoa has a bridge loan commitment from Goldman Sachs Bank USA of up to $3.1 billion to help fund the cash portion.
Key points
- Upfront consideration: $3.1 billion in cash, subject to adjustments, plus about 17 million Alcoa shares, roughly 6% of shares outstanding after issuance
- At least half of the shares will be distributed to South32 shareholders in a specie distribution; the rest may be sold by South32 in an orderly manner
- Contingent value right: up to $750 million in cash over four annual periods starting July 1, 2026, based on alumina and aluminum prices exceeding agreed strike prices
- Expected closing in the first half of 2027; termination payments of $41 million or $82 million to Alcoa and $82 million from Alcoa in certain cases
