"Overall earnings and cash flow were up pretty significantly year on year," Exxon Chief Financial Officer Kathryn Mikells told Reuters.
"So that came really from a combination of strong markets, strong throughput, strong production, and really good cost control."
Exxon boasted that its cash flow from operations soared to $76.8 billion last year, up from $48.1 billion in 2021.
Part of it is explained by rising costs in the Permian, with inflation in the double digits, amid "really, really hot" demand for equipments and services, he said.
Exxon's results come ahead of what are expected to be strong earnings from Shell plc on Thursday and from BP plc and TotalEnergies next week.
