Alcoa Completes Divestiture of Wire Harness and Electrical Distribution Business To Platinum Equity

June 15, 2009

NEW YORK–Alcoa (NYSE:AA) announced today that it has completed the divestiture of
its wire harness and electrical distribution business to Platinum
Equity, a California-based private equity group. Terms of the
divestiture were not disclosed. The wire harness and electrical
distribution business is the largest part of the Alcoa Electrical and
Electronic Solutions business which the Company announced was for sale
in January.

The divestiture of the Electrical and Electronic Solutions business is
part of a multi-pronged effort to focus on businesses where Alcoa brings
strong technical and parental advantage. The effort will provide better
focus of resources on strategic businesses, improve financial
performance and establish a strong foundation for growth.

The wire harness and electrical distribution business has operations in
13 countries around the world and employs approximately 17,500 people.
With the transaction, Alcoa now employs approximately 63,000 employees
in 31 countries across the world. Alcoa expects to record a loss in
discontinued operations in the second quarter of 2009 in connection with
the closing of the transaction.

Alcoa is continuing discussions with multiple parties on the sale of the
remainder of the Electrical and Electronics business which consists of
the electronics portion of the operation. That business has
approximately 500 employees in three European countries.
