FirstEnergy shared that the board of directors has unanimously agreed to appoint Brian X. Tierney as president and chief executive officer, effective June 1, 2023.

He succeeds interim President and Chief Executive Officer John W. Somerhalder II. 

Mr. Somerhalder also serves as chair of FirstEnergy's board, a position he will continue to hold. After FirstEnergy's May 2023 annual meeting, Mr. Tierney is expected to be appointed by the board to serve as a director effective June 1.

Mr. Tierney, 55, joins FirstEnergy from Blackstone, where he serves as the global head of Portfolio Operations and Asset Management for the Infrastructure group.

He previously spent 23 years at Ohio-based American Electric Power Company, Inc. (AEP,) one of the United States' largest investor-owned utilities, where he held a number of leadership positions, including most recently serving as executive vice president of Strategy following more than 11 years as its chief financial officer.

Leading From Within

With a career spanning 28 years in the industry, Mr. Tierney has developed extensive leadership, operational and commercial experience.

Moreover, he brings to FirstEnergy strong financial acumen — across capital allocation, accounting, investor relations, planning and strategy, and risk management — and a demonstrated ability to advance business strategies and drive value creation.

"Brian Tierney is a proven leader with deep experience in the energy industry, a unique blend of operational, financial, and strategic skills, and a sterling record of driving growth and transformation within our sector," said Mr. Somerhalder.

Mr. Tierney said, "I have dedicated my career to the energy industry, and leading FirstEnergy is a privilege that I am humbled by and a responsibility that I take seriously. I believe strongly in the steps the company's board and management have taken to position the business for long-term stability and success, and I look forward to working with them to execute this strategy and build on FirstEnergy's strong operational momentum. I appreciate the board's confidence in me and will do everything I can to serve our customers and communities, keep our employees safe and move FirstEnergy into the future."
