Dunham praised McClendon and expressed confidence in Dixon's management in the future.
“We are all thankful to Aubrey for his many contributions over the last 24 years in helping to build the company to this point,” Dunham said.
“The next phase of our company's growth requires operational excellence, balance sheet discipline, cost control, environmental and safety focus and a commitment to all of our stakeholders that everything we do will be done with the highest standard of corporate and personal integrity. Steve has those skills. He has the reins, and he knows the path forward.”
