Alcoa Corp. has agreed to acquire South32 Ltd.’s aluminium-related assets in a deal valued at as much as $5.6 billion, according to multiple reports. The transaction covers upstream production assets, including bauxite, alumina and aluminium operations located in Australia, Brazil and South Africa. Bloomberg and other outlets describe the arrangement as a move to strengthen Alcoa’s position among the world’s largest aluminium producers in anticipation of long-term demand growth.

Some sources report different deal values and structures. Yahoo Finance cites an announced figure of about $4.1 billion for the Alcoa acquisition, while also reporting that South32 agrees to a conditional $5.6 billion sale. Other Australian publications describe the transaction as an “$8 billion deal,” without further detail, suggesting variations in how total value is presented across filings or currency/valuation components. Overall, the coverage is consistent that the transaction is conditional and involves the transfer of South32’s aluminium supply-chain assets across the three countries.
