Trimet says Alcoa-South32 deal creates Brazil duopoly, urges block
Trimet, a German aluminum producer, has requested Brazil's competition authority to block Alcoa's acquisition of South32's alumina business. Trimet argues the deal would reduce Brazilian suppliers of smelter-grade alumina to two and give the merged entity 52% of third-party sales, potentially controlling the global alumina price benchmark. The transaction would also reverse a 25-year-old structural remedy imposed on Alcoa.
