Alcoa to Permanently Close Remaining Potlines at Massena East Smelter

January 15, 2014

Closure Furthers Alcoa’s Strategy to Lower Cost Base in Commodity Business

Alcoa (NYSE: AA) today announced it will permanently close the remaining
two potlines at its Massena East smelter in New York in the first
quarter of this year. The decision was made because the potlines are no
longer competitive. One of three potlines at the facility was
permanently closed in August 2013. The closure will reduce Alcoa’s
smelting capacity by 84,000 metric tons. The Massena West facility will
continue to operate.

“We will be working with our unions, state, local and other stakeholders
to minimize the impact of these changes,” said Bob Wilt, president of
Alcoa Global Primary Products. “We appreciate the support of the New
York Power Authority and will work with them and others to ensure our
continuing success at Massena West.”

Alcoa’s review of its primary metals operations is consistent with the
Company’s 2016 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.

In 2013, the Company met its goal of lowering its cost position in both
aluminum smelting and alumina refining, having reached the 43rd
percentile on the global aluminum cost curve, and 27th percentile on the
global alumina cost curve. These shifts represent an 8 point movement
and 3 point movement, respectively, since 2010.

Including the closure of the remaining two potlines at Massena East,
Alcoa has announced closures or curtailments representing 361,000 metric
tons of the 460,000 metric tons placed under review in May of 2013. Once
the Massena East potline closure is complete, Alcoa will have total
smelting operating capacity of 3,950,000 metric tons, with approximately
655,000 metric tons of capacity idle.

“We are taking decisive action to close the remaining potlines, given
they are no longer competitive,” Wilt added. “We continue to reshape our
commodity business to ensure it is positioned for long-term success.”

Total restructuring-related charges for the first quarter of 2014
associated with the above closure are expected to be between $60 and $70
million after-tax, or $.06 per share, of which approximately 40 percent
is non-cash.
