• Headquarters relocation accelerates Company's strategy to connect its leading scale to growing markets
• Company reaffirms synergy, capital and operating outlook for the fourth quarter and full year 2025

Expand Energy Corporation has announced plans to relocate its corporate headquarters from Oklahoma City, Oklahoma, to Houston, Texas, in mid-2026. The relocation, which will primarily focus on the executive leadership team, will strengthen Expand Energy’s relationships with key industry and commercial partners in support of the Company’s long-term growth objectives. Oklahoma City will remain an important center of excellence for Expand Energy’s business and operations, and the Company remains committed to supporting its Oklahoma City employees and the local community.

The Company also announced leadership changes, effective immediately. Michael Wichterich, Chairman of the Board, has been appointed Interim President and Chief Executive Officer, succeeding Domenic (Nick) J. Dell’Osso, Jr. Dell’Osso has stepped down as a director of the Board and will serve as an external advisor for a period of time to ensure a smooth transition. The Board is commencing a search for a permanent CEO with the assistance of an independent recruitment firm.

“On behalf of the Board, I want to thank Nick for his leadership and many contributions since first joining the company in 2008,” said Wichterich. “During his tenure as CEO, the Company has grown from a $5 billion business to a $26 billion investment-grade enterprise included in the S&P 500 Index. We are grateful for his leadership in setting a strong foundation for our future.”

Wichterich continued, “Building on our positive momentum going into 2026, our new headquarters, supported by our outstanding teams in Oklahoma City and the field, will enable us to capitalize on Houston’s leading role as a gateway to the global natural gas market. As North America’s largest natural gas producer, this will accelerate our strategy to provide affordable, reliable, lower carbon energy to growing domestic and global markets.”

Dell’Osso said, “It has been a privilege to lead and work alongside the Expand Energy team as we have grown and evolved. I am proud of what we have accomplished together and confident that Expand Energy will continue to thrive and support energy access for a more secure and sustainable future.”

Matt M. Gallagher, Lead Independent Director, said, “Mike is the right leader to step into the role of Interim CEO and maintain continuity while we make the strategic move to Houston. He knows our company deeply, has extensive relationships across the oil and gas industry, and is an entrepreneurial leader with a track record of success. The Board looks forward to working with Mike and the executive team to facilitate a smooth transition and continue to position the Company for long-term success.”

Wichterich has served as Chairman of Expand Energy’s Board of Directors since 2021, as well as Interim CEO from April to October 2021. He is the Founder and CEO of Three Rivers Operating Company LLC, a private exploration and production company with a focus in the Permian Basin. He has also served on the boards of multiple public and private companies.
