Alcoa Recognized as One of the 50 Most Engaged Workplaces? in the United States

Alcoa (NYSE:AA) announced today it has been recognized as one of the 50
Most Engaged Workplaces? in the United States byAchievers,
a leader in employee reward and recognition solutions. This is the
second year in a row Alcoa has received the award for leadership and
innovation in engaging its employees.

'We place great value on our employees and take their engagement very
seriously,' said Mike Barriere, Alcoa Vice President, Human Resources.
'At Alcoa, we use a statistical technique to identify engagement drivers
specific to each of our operating locations. This helps prioritize
activities that will yield the greatest impact on employee engagement.
This process is not common practice for companies that measure employee
engagement, and differentiates us from our peers.'

Winners were evaluated on commitment to employee engagement in eight
areas: Communication, Leadership, Culture, Rewards & Recognition,
Professional & Personal Growth, Accountability & Performance, Vision &
Values and Corporate Social Responsibility.

'Companies that focus on employee engagement tend to perform better
financially, attract and retain the best talent and enjoy improved
customer service and client retention,' said Razor Suleman, Founder and
Chairman of Achievers. 'These companies
serve as role models for other businesses to engage their own employees
and build success.'

Alcoa will be honored alongside other recipients of the Achievers
50 Most Engaged Workplaces? Award at a gala on October 25,2012, in San Francisco.
