FORT COLLINS, Colo., June 2, 2014—Advanced Energy Industries, Inc. (Nasdaq:AEIS), a leader in precision power conversion, today announced that after nearly three years at the helm, Garry Rogerson has decided to step down from his role as chief executive officer. Until a successor is identified, Garry will continue to lead the strong management team at Advanced Energy.

"Having made enormous strides on our strategic plan to drive revenue growth, expand margins and increase cash generation, I believe this is a great time to begin a new chapter—both for our company and for me," said Garry Rogerson, CEO of Advanced Energy. "I am incredibly proud of the team and all that we have accomplished in redefining Advanced Energy as a leader across a growing number of applications and geographies and driving increased growth and profitability. I believe the company is well positioned for continued success, and the time is right for us to search for my successor. Until my replacement is found, we will continue to focus on the strategic objectives laid out at our analyst day in November."
