Alcoa to Sell Stake in Jamalco to Noble

October 15, 2014

Alcoa (NYSE: AA) and Noble Group Ltd (SGX: N21) today announced the
signing of a definitive agreement that will result in Alcoa World
Alumina and Chemicals (AWAC) selling 100 percent of its ownership stake
in the Jamalco bauxite mining and alumina refining joint venture to
Noble for $140 million. AWAC will continue as the managing operator for
three years under a compensated service agreement and employees will
remain employed by Jamalco.

The Jamalco joint venture is 55 percent owned by Alcoa Minerals of
Jamaica (AMJ) and 45 percent owned by Clarendon Alumina Production Ltd.
(CAP). AMJ is part of the AWAC joint venture, owned 60 percent by Alcoa
and 40 percent by Alumina Limited. CAP is a company wholly owned by the
Government of Jamaica.

“The decision to sell AWAC’s stake in Jamalco is in line with Alcoa’s
global strategy to reshape its upstream portfolio and lower the cost
base of our commodity business,” said Bob Wilt, President, Alcoa Global
Primary Products. “The sale will help achieve those goals, while
maintaining jobs and protecting the economic contributions of Jamalco to

Mark Hansen, Head of the Metals Division at Noble Group commented, “This
transaction will provide Noble with an additional 778,800 metric tons of
annual alumina off-take while the Jamaican government retains its 45
percent ownership of the joint venture. This is consistent with Noble’s
strategy to secure supply for customers while working with best in class
operators such as Alcoa. Noble looks forward to partnering with the
Government of Jamaica to continue to build on Jamalco’s robust operating
history, and implement an energy solution that will enhance the
efficiency of the plant.”

The sale is subject to customary regulatory approvals, and is expected
to close by the end of the fourth quarter 2014. As a result of the
transaction, Alcoa will record a non-cash loss of approximately $80
million to $100 million, or between $0.07 and $0.09 per share, after-tax
and non-controlling interest in the fourth quarter. This sale is in line
with Alcoa’s strategy to create a globally competitive commodity
