Alcoa to Close Poços Smelter in Brazil

June 30, 2015

Lightweight metals leader Alcoa (NYSE:AA) today announced that it will
permanently close its Poços de Caldas primary aluminum smelter in Brazil
on June 30, 2015. The smelter has been curtailed since May 2014 and the
underlying market conditions that led to the curtailment have not

“The closure of the Poços smelter permanently removes a high-cost
smelting facility from the Alcoa system and is another step in creating
a more profitable Primary Metals business,” said Alcoa Global Primary
Products President Bob Wilt.

Once the Poços smelter is closed, Alcoa’s total global smelting capacity
will be reduced by 96,000 metric tons, to 3.4 million metric tons. The
Poços mine, refinery, aluminum powder plant and casthouse will continue
normal operations.

As a result of the closure, Alcoa expects to record
restructuring-related charges in second quarter 2015 between $100
million and $110 million after-tax, or $.08 to $.09 per share, of which
approximately 60 percent is non-cash.
