J.R. Sult, executive vice president and CFO, has elected to leave Marathon Oil for personal reasons following an appropriate transition period.
Sult's departure is not related to any disagreement with the company regarding financial disclosures, accounting or business matters, Marathon Oil said in a press release.
Pat Wagner has been appointed interim chief financial officer while the company conducts a search for a new CFO. Wagner, vice president of corporate development and strategy, joined Marathon Oil in 2014. He has extensive financial and operational experience, including senior roles at QR Energy LP, Scotia Waterous, and Devon Energy Corp.
"Pat brings a solid balance of financial and operating skills to his role as interim CFO and will continue to support our ongoing focus on financial discipline during this transition," Tillman said.
"I want to sincerely thank J.R. and Lance for their substantial contributions to the Company over the years and wish them both well in their future endeavors."
