Alcoa to Curtail 147,000 Metric Tons of Aluminum Smelting Capacity in Brazil

March 28, 2014

Company will have 21% of smelting capacity offline when actions complete

Alcoa (NYSE: AA) today announced it will curtail 147,000 metric tons of
smelting capacity at its São Luís (Alumar) and Poços de Caldas smelters
in Brazil due to challenging global market conditions in primary
aluminum and increased costs that have made the smelters uncompetitive.
The curtailments are expected to be complete by the end of May 2014.

In 2013, the Company curtailed 34,000 metric tons at Poços and 97,000
metric tons at São Luís. The new curtailments will include the remaining
62,000 metric tons of capacity from the Poços smelter, resulting in a
full curtailment of its three potlines. Another 85,000 metric tons will
be curtailed at São Luís.

“Across the globe, we are taking measures to curtail high-cost smelting
capacity that is not competitive and reshape our cost profile,” said Bob
Wilt, President of Alcoa Global Primary Products. “These are difficult
but necessary actions in support of Alcoa’s strategy to lower the cost
base of our upstream businesses.”

As a result of the smelter curtailment, the Poços refinery will also
reduce production accordingly. The mine, aluminum powder plant and
casthouse at Poços will continue normal operations, as will the refinery
at São Luís. Other Alcoa operations in Brazil are not affected.

“We know how deeply this decision affects our employees, our contractors
and our communities,” said Aquilino Paolucci, President of Alcoa Latin
America and the Caribbean. “While our teams have worked incredibly hard
to make these facilities more competitive, we must take steps regarding
our primary metal production in Brazil given the market conditions we
are facing. We appreciate the support of governments at all levels, and
will actively work in partnership with our employees, unions, and
community stakeholders to manage through this transition and minimize
the impact.”

In May 2013, Alcoa placed 460,000 metric tons of smelting capacity under
review. Once all announced curtailments and closures are complete, Alcoa
will have approximately 800,000 metric tons, or 21 percent, of smelting
capacity offline.

Total restructuring-related charges associated with the Brazil
curtailments in the first quarter are expected to be between $40 million
and $50 million after-tax, or $0.04 to $0.05 per share, of which
approximately 30 percent would be non-cash.

Alcoa’s review of its primary metals operations is consistent with the
Company’s goal of lowering its position on the world aluminum production
cost curve to the 38th percentile and the alumina cost curve
to the 21st percentile, by 2016.
