Rio Tinto Group (LSE:RIO) and Chinalco have agreed to acquire a controlling stake in Brazil based aluminium producer Companhia Brasileira de Alumínio (CBA). The deal gives Rio Tinto a larger presence in Latin American aluminium, extending its integrated position across bauxite, alumina and primary metal. The transaction represents a new phase of international expansion for Rio Tinto in a core business line alongside its iron ore and copper operations.

For investors watching LSE:RIO, this move comes at a time of strong recent share performance. The stock is trading at £70.83, with returns of 17.9% over the past 30 days, 18.3% year to date and 51.8% over 1 year, while the 5 year return stands at 70.7%. These figures are the context in which the CBA deal is taking place, during an already active period for the company.

The new stake in CBA gives Rio Tinto additional exposure to Latin American aluminium at a time when it is already a key global producer. As the transaction closes and integration progresses, investors may monitor how management prioritises capital allocation between aluminium and other segments, and how this larger footprint affects Rio Tinto's longer term business mix.
