History

Alumina was founded in December 2002 when Western Mining Corporation spun off its aluminium and bauxite assets.^[1]

Alumina's only business activity is as the owner of a 40% share in Alcoa World Alumina & Chemicals (AWAC), a joint venture with Alcoa. AWAC owns two bauxite mines and three refineries (to extract aluminium oxide from bauxite) in Western Australia and owns a smelter (to extract pure aluminium) and has a 55% interest in the Portland aluminium smelter. AWAC also operates and has interests in Brazil, Guinea, Saudi Arabia and Spain.^[2]

In 2016, Alumina Limited achieved great short term authority over its interest in AWAC with more influence over a broader suite of operational and investment decisions.^[3]

Having been cross-listed on both the Australian Securities Exchange (ASX) and New York Stock Exchange (NYSE), Alumina delisted from the NYSE in February 2014, consolidating on the ASX.^[4][5]

In February 2024, Alcoa announced it would acquire Alumina for $2.2 billion in an all-stock deal. As part of the deal Alcoa would gain full ownership of AWAC.^[6] The acquisition was completed in August.^[7]
