Alcoa to Close Warrick Smelter and Curtail Remaining Capacity at Pt. Comfort Refinery

January 7, 2016

Actions continue to drive competitiveness of Upstream operations

Lightweight metals leader Alcoa (NYSE:AA) today announced it is taking
further action to increase the competitiveness of its Upstream business
amid prevailing market conditions. In 2015, the Midwest transaction
aluminum price dropped approximately 30 percent, and the Alumina Price
Index fell approximately 40 percent.

Alcoa will permanently close its 269,000 metric ton Warrick Operations
smelter in Evansville, Indiana by the end of the first quarter 2016. By
the end of the second quarter 2016, the Company will reduce alumina
production by one million metric tons, which includes curtailing the
remaining 810,000 metric tons of refining capacity at its Point Comfort
operations in Texas.

The rolling mill and power plant at Warrick Operations will continue to
operate.

“We recognize how deeply this decision impacts employees and we are
committed to work closely with our employees, unions and community
stakeholders to support them through this transition,” said Roy Harvey,
President of Alcoa’s Global Primary Products. “Despite the hard work of
employees, these assets are not competitive. We’re confident that these
actions are the right ones in face of these challenging market
conditions. We are committed to creating a resilient business ready for
launch as an independent company in 2016.”

Once the actions announced today and in the fourth quarter are
implemented, Alcoa will have curtailed or closed 812,000 metric tons of
smelting capacity and 3.3 million metric tons of refining capacity since
its announced review in March 2015 of 500,000 metric tons of smelting
capacity and 2.8 million metric tons of refining capacity.

Alcoa forecasts improving supply-demand balances in both the alumina and
aluminum markets for 2016, and is focused on positioning the business
for success throughout market cycles. The company is on target to meet
or exceed its 2016 goals of moving to the 38th percentile on
the aluminum cost curve and 21st percentile on the alumina
cost curve.

As of result of today’s announcement, the Company will record an
associated charge in the fourth quarter of approximately $120 million
after-tax, or $0.09 per share, of which approximately 45 percent will be
non-cash. Additional charges in the first quarter of 2016 related to
these actions are expected to be between $50 million and $60 million
after-tax, or $0.04 to $0.05 per share, of which almost 80 percent will
be non-cash.

As previously announced, Alcoa will separate into two, industry-leading
publicly traded companies in the second half of 2016 – an
Upstream-focused company including its Mining, Refining, Smelting,
Energy and Casting businesses, and a Value-Add company including its
Global Rolled Products, Engineered Products and Solutions, and
Transportation and Construction Solutions businesses.

Pt. Comfort is part of the Alcoa World Alumina and Chemicals group of
companies owned 60 percent by Alcoa Inc., and 40 percent by Alumina
Limited.
