AES Announces CFO Transition Plan

ARLINGTON, Va., April 30, 2012 - The AES Corporation (NYSE:AES) today announced that after more than six years of service leading AES’ finance functions, AES Chief Financial Officer (CFO) and President of Global Business Services, Victoria Harker, intends to leave the company no later than August 10, 2012.

“Victoria made a great contribution to AES, creating a first rate finance department and a strong culture of financial controls. I am personally very grateful to her for helping me during my transition to the role of CEO and implementing the first phase of our new strategic plan,” said Andrés Gluski, AES President and Chief Executive Officer. “We’ll continue to build on her accomplishments, including greater use of the Global Shared Services unit which she launched last year to improve returns at our existing businesses.”

Ms. Harker said, “I am very proud to have been part of our successful financial evolution at AES over the past six years. The team has never been stronger or better equipped to drive the business efficiently and effectively. I look forward to the new challenges ahead.”

During Ms. Harker’s tenure as CFO, she led an important realignment of the AES Global Finance function, which consolidated the number of finance teams across the globe and resulted in improved reporting and efficiency. She also initiated the AES Finance Leadership Development Program at the Darden School of Business.
