Oliphint will succeed current CFO George Glyphis, who will retire effective March 1, 2023, while Gray will succeed executive chairman Sean Smith, who will retire effective Dec. 31, 2022.

Bringing nearly two decades of upstream advising experience, Oliphint served as Jefferies LLC's marketing director and co-head of upstream Americas in the company's Energy Investment Banking Group prior to his new appointment.

"Having worked very closely with Guy on several critical strategic and financial transactions for legacy Centennial, I know he is one of the most talented and qualified finance professionals in the sector,” Glyphis, said in the release. “I’m excited to partner with Guy as he prepares to lead the finance function of Permian Resources and have no doubt he will do an outstanding job."

Meanwhile, Gray founded and served as director, CEO and board director of RSP Permian before it merged with Concho Resources. With over 40 years of operational and financial experience within the oil and gas industry, he also serves on the Range Resources Corp. board of directors.

Glyphis intends to remain with the company in a senior advisory role until his retirement mid-2023.

"On behalf of the board and the entire organization, I want to thank Sean and George for their leadership and dedicated service," co-CEO Will Hickey commented in the release. “Their impact to legacy Centennial following the global pandemic and contribution to Permian Resources during the merger integration cannot be understated."
