Alcoa Corporation reported production results for the fourth quarter and full year ended December 31, 2023. For the quarter, the company reported Alumina production decreased 1% sequentially to 2.79 million metric tons on lower production from the Australia refineries. In Aluminum, Alcoa produced 541,000 metric tons, a 2% increase from the third-quarter?s strong output.

For the year, Alumina production decreased 13% annually primarily due to lower grade bauxite at the Australia refineries and partial curtailments at the San Ciprián refinery in Spain and the Kwinana refinery in Australia. Aluminum production increased 5% annually, primarily due to the restart of the Alumar smelter in Brazil.
