Alcoa is taking decisive action to curtail uncompetitive smelting and refining capacity to ensure continued competitiveness amid prevailing market conditions.

The company will reduce aluminium smelting capacity by 503,000 metric tons and alumina refining capacity by 1.2 million metric tons. Alcoa will begin the curtailments in the fourth quarter of 2015 and will complete them by the end of the first quarter of 2016.

The reductions will further improve the cost position of the Upstream business and ensure competitiveness in a lower pricing environment, including a 30 percent drop in the Midwest transaction aluminium price year-to-date.

Alcoa has been aggressively reshaping its Upstream portfolio as part of a successful multi-year strategy to position itself as a low-cost global leader in alumina and aluminium production. Once these actions are complete, Alcoa will have closed, divested or curtailed 45% of total smelting operating capacity since 2007.
