February 2, 2011

NEW YORK–Alcoa (NYSE:AA) announced today it again has achieved the top spot in
the Basic Resources category in the annual Covalence Ethical Rankings, a
major international survey that measures the ethical performance of
multinational companies.

Covalence’s reputation index, distributed by Thomson Reuters, Bloomberg
and Capital IQ, is a barometer of how multinationals are perceived in
the ethical field, and measures performance across a range of criteria
such as labor standards, waste management, product social utility and
human rights policy.

Alcoa has been rated No. 1 in the basic resources category since the
ranking began in 2005. Alcoa placed 15th overall in 2010 across 18
sectors and 581 companies tracked.

“To be ranked number one in our industry in the 2010 Covalence rating
confirms the values and integrity Alcoans have embodied for years. We
hold ourselves to the highest ethical business practices, combined with
a profound respect for the individual and a strong responsibility toward
the environment,” said Alcoa Chairman and Chief Executive Officer Klaus
Kleinfeld.

“I am pleased that Alcoa’s solid ethical foundation and practices
continue to be recognized by organizations such as Covalence.”
