Expand Energy has appointed Marcel Teunissen as its new CFO, effective immediately. He replaces Mohit Singh, whose employment was terminated in August 2025.

Nick Dell’Osso, the CEO (and former CFO between 2010 and 2021) was ousted in February 2026. Michael Wichterich, the Chairman of the Board, is also the interim CEO currently.

Expand is the new name for the Chesapeake and Southwestern Energy merger that was completed in October 2024. In February, the company announced it would move its headquarters from Oklahoma City to Spring, TX.

Mr. Teunissen was most recently the President of the North American operations of Parkland Corporation, a Canadian fuel distributor. Parkland was publicly-traded until it was acquired by Sunoco in November 2025. Mr. Teunissen has been in the role for about 10 months. Prior to that, he spent four years as CFO of Parkland. Before joining Parkland, Mr. Teunissen had a 23-year career at Shell.

Mr. Teunissen will receive a base salary of $550,000.

Brittany Raiford, who had been serving as interim CFO, will revert back to her former role as Vice President – Treasurer and Investor Relations.
