AES Announces CFO Transition

ARLINGTON, Va., September 21, 2021 – The AES Corporation (NYSE: AES) announced today the appointment of Stephen Coughlin as Executive Vice President and Chief Financial Officer, effective October 15, 2021. Most recently, Coughlin led AES’ Corporate Strategy and Financial Planning groups, including serving as the Chair of the Company’s Investment Committee. Prior to that role, he served as the Chief Executive Officer of Fluence, AES’ energy storage joint venture with Siemens. Coughlin succeeds Gustavo Pimenta, who will be joining Brazilian mining company, Vale S.A., as Chief Financial Officer.

“Steve Coughlin brings a wealth of clean energy and finance experience that will serve us incredibly well. We are thrilled that he will be joining the senior leadership team,” said Andrés Gluski, AES President and Chief Executive Officer. “I also want to thank Gustavo Pimenta for his meaningful contributions as CFO, including leading the transition to becoming an investment grade company. We have worked hand-in-hand to deliver on all of our strategic and financial goals, including the rapid expansion of our renewables and energy storage businesses, and I wish him the best in his new role.”

“I am proud to have contributed to AES’ transformation to one of the leading companies for innovation in the sector,” said Gustavo Pimenta. “It was a pleasure to work with such a talented team and I see AES as positioned for great success in the future.”

Coughlin joined AES in 2007 in the finance team of the then-AES wind generation organization. He subsequently served in a variety of leadership roles at AES, including leading the energy storage business through a phase of rapid expansion and serving as the founding CEO of Fluence.
