Alcoa Names Tony Thene CFO for Engineered Products and

Solutions group; Graeme Bottger Elected Alcoa Controller

New York, NY, July 23, 2010 — Alcoa announced today that two senior finance executives will swap positions so each can broaden his experience within the global aluminum company. Effective August 1, Tony R. Thene, Alcoa Vice President and Controller, has been named Chief Financial Officer of Alcoa’s Engineered Products and Solutions business group (EPS), and Graeme Bottger, currently EPS Chief Financial Officer, has been elected to succeed Mr. Thene as Alcoa Vice President and Controller.

“Tony moves to the top finance position in EPS at a time when our downstream business is pursuing an external growth strategy and strengthening productivity, both areas where his controller background will be beneficial to EPS,” said Alcoa Executive Vice President and Chief Financial Officer Chuck McLane.

Mr. Thene will remain a Vice President of Alcoa and has been named to the Company’s Executive Council. He has served with Alcoa for 21 years.

Mr. Bottger, in his new role, will be responsible for global business services for Alcoa.

“In Graeme’s 29-year Alcoa career, he has held a broad range of global operating and corporate positions that prepare him well for his new assignment as Alcoa’s Controller,” McLane said. “During his five years as EPS CFO, the group grew dramatically in size and importance within the Alcoa portfolio.”

Mr. Bottger was elected an officer of Alcoa and will remain a member of the Company’s Executive Council.
