Alcoa Defense Wins Contract to Supply Austal Sheet and Plate

Alcoa (NYSE:AA) announced today that it has won a contract to supply
5XXX-series alloy sheet and plate through 2014 for all AUSTAL USA
vessels, including commercial ships and U.S. Navy ships such as the
Joint High Speed Vessel (JHSV) and all future platforms.

'We are pleased that Austal, the world′s premier aluminum shipbuilder,
has selected Alcoa aluminum for its next-generation naval vessels,? said
David Dobson, president, Alcoa Defense. 'In the past three years, we
have established Alcoa Defense as the leading provider of aluminum
products and design services that reduce weight and enhance the
performance of Navy ships.?

The marine sheet and plate will be produced at Alcoa′s Davenport (Iowa)
Works. In addition to supplying marine sheet and plate for military
vessels, Alcoa also will supply products for Austal′s commercial
vessels. The materials will be provided through Pierce Aluminum,
Austal′s chosen service center for management of sheet and plate
logistics.

'One of the reasons Austal selected Alcoa aluminum for this critical
supply contract is the unmatched dimensional capabilities of our rolling
mills ? delivering the widest range of sizes available in the industry,?
said Brian Pendrak, market manager of industrial products for Alcoa′s
North American Rolled Products division, which is producing the
materials.
