Alcoa Continues Reshaping Upstream Business, 443,000 Metric Tons of Suralco’s Refining Capacity to be Curtailed

March 17, 2015

Alcoa and Government of Suriname pursuing potential transfer of Suralco to Government and sustaining country’s bauxite industry

Lightweight metals leader Alcoa (NYSE: AA) today announced
that it plans to curtail 443,000 metric tons per year (mtpy) of alumina
refining capacity at Suralco in Suriname. In addition, the Company and
the Government of Suriname have agreed to pursue a transaction for a
Government-owned entity to acquire the Suralco operations.

The curtailment and potential transaction are in line with Alcoa’s
recent announcement to review upstream capacity for possible curtailment
or divestiture and the Company’s strategic goal to create a globally
competitive commodity business. The curtailment, which represents one
digester, is expected to be complete by April 30, 2015.

“Reducing the production of the refinery will assist in extending the
life of the operations as we continue to work with the Government of
Suriname on the transaction,” said Bob Wilt, President Alcoa Global
Primary Products. “We are committed to working with the Government to
find the best solution for the Suralco facility.”

In October 2014, the Government and Alcoa signed a Memorandum of
Understanding reflecting both parties’ intent to find a solution for the
future of Suralco, which operates in a challenging global environment,
with limited bauxite reserves and lacks a long-term energy solution. The
resulting discussions between the parties have led to the Government’s
decision to sustain the bauxite industry in Suriname.

Both parties now intend to pursue a transaction where a Government-owned
entity would acquire Suralco, including the mining, refining and Afobaka
hydroelectric operations. Following the appropriate due diligence, the
parties are targeting to reach agreement on the proposed transaction by
July 1, 2015.

The Company will work closely with unions and employees to reduce the
impact of the curtailment on affected employees by offering fair
severance packages. The Paranam refinery and related mining operations
employ approximately 700 people, in addition to contracted personnel.

The net financial impact associated with the curtailment is not expected
to be material to the Company’s earnings.

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

Suralco’s total refining capacity is 2.2 million mtpy, with 876,000 mtpy
currently idled. Suralco is part of the Alcoa World Alumina and
Chemicals group of companies owned 60 percent by Alcoa Inc. and 40
percent by Alumina Limited.
