Alcoa to Curtail Smelting Capacity in Brazil as Reshaping of Upstream Portfolio Continues

March 30, 2015

Lightweight metals leader Alcoa (NYSE: AA) today announced
that it will curtail the remaining 74,000 metric tons of smelting
capacity at its São Luís (Alumar) facility in Brazil. The decision is
aligned with the Company’s recent
to evaluate upstream capacity for possible curtailment,
closure or sale as Alcoa further optimizes its commodity portfolio. The
curtailment is expected to be complete by April 15, 2015.

“We continue to take decisive steps to create a globally competitive
commodity business and are executing against our upstream capacity
review,” said Bob Wilt, President of Alcoa’s Global Primary Products.
“These are difficult but necessary actions in support of Alcoa’s
strategy to lower the cost base of our upstream businesses.”

This curtailment adds to the 85,000 metric tons of capacity idled at São
Luís in
May 2014
and the 12,000 metric tons curtailed in October 2014.
Challenging global market conditions in primary aluminum production and
increased costs have made the smelter uncompetitive. The refinery at São
Luís is unaffected and will continue normal operations.

“We understand how deeply this decision affects our employees, our
contractors and our communities,” said José A. Drummond, President of
Alcoa Latin America. “Our teams have worked extremely hard to make the
plant competitive, and we will actively consult with our employees,
unions and community stakeholders to minimize the impact of this action.
We will continue working to achieve the competitive conditions necessary
for aluminum production in the region.”

The curtailment is in line with Alcoa’s announcement on March 6, 2015 to
evaluate 500,000 metric tons of smelting capacity and 2.8 million metric
tons of refining capacity for possible curtailment, closure or sale.
Once the São Luís facility is curtailed, Alcoa will have approximately
740,000 metric tons, or 21 percent, of its smelting capacity offline.

As a result of today’s announcement, Alcoa will record a
restructuring-related charge in the first quarter expected to be between
$10 million and $15 million after-tax, or $0.01 per share.

By curtailing high-cost smelting and refining capacity, Alcoa
supports its goal of lowering its position on the global aluminum cost
curve to the 38th percentile and the global alumina cost
curve to the 21st percentile, by 2016.
