Alcoa expands upstream portfolio with major South32 deal
Shares of Alcoa Corporation (NYSE:AA) declined nearly 5% in pre-market trading on Wednesday after the aluminium producer agreed to acquire South32’s bauxite, alumina and aluminium operations in a transaction valued at $4.1 billion.
The acquisition includes South32’s stakes in the Boddington bauxite mine and Worsley alumina refinery in Western Australia, the Hillside aluminium smelter and the idled Bayside smelter property in South Africa, along with the Mineração Rio do Norte bauxite mine and the Alumar alumina refinery and aluminium smelter in Brazil. The Mozal aluminium smelter in Mozambique is not part of the agreement.
Cash and shares form purchase consideration
Under the terms of the deal, Alcoa will pay $3.1 billion in cash and issue approximately 17 million new shares valued at around $1.0 billion.
Following completion, the newly issued shares will account for roughly 6% of Alcoa’s total shares outstanding.
South32 could also receive up to $750 million through a contingent value right linked to future alumina and aluminium prices over four annual measurement periods beginning on July 1, 2026.
Acquisition expected to boost earnings and cash flow
Including net debt, primarily associated with financing leases, the transaction carries an implied enterprise value of approximately $4.7 billion.
Alcoa expects the acquisition to generate synergies with a net present value of around $900 million and anticipates the deal will immediately enhance both earnings per share and free cash flow once completed.
On a pro forma basis, the combined business would have produced approximately 3.2 million metric tonnes of aluminium and 14.8 million metric tonnes of alumina during 2025.
To finance the acquisition, Alcoa has secured a fully committed $3.1 billion bridge financing facility from Goldman Sachs.
Analysts see stronger vertical integration
JPMorgan analyst Bill Peterson reiterated a Neutral rating on Alcoa shares with a $70 price target following the announcement.
“While this deal has been hypothesized before, if approved, the transaction would meaningfully expand Alcoa’s vertical integration into strategically attractive bauxite, alumina, and smelting assets,” Peterson said.
Closing targeted for first half of 2027
The acquisition is expected to close during the first half of 2027, subject to approval from South32 shareholders, regulatory clearances and the satisfaction of customary closing conditions.
