Kathryn Mikells

Kathryn Mikells joined Exxon Mobil in 2021 as SVP and chief financial officer. Before joining the largest investor-owned energy company in the world, she spent six years as CFO of London-based Diageo. She is Exxon’s first official CFO; before her appointment, the finance duties were shared across a range of executive roles. Mikells is the first woman to join the management committee of Exxon. For the full year 2024, Exxon Mobil reported total revenue of $349.6 billion, up 1.5% year over year. Mikells oversees the company’s disciplined spending strategy; she is also managing the company's plans to pursue more than $20 billion in lower-emission investments through 2027. She played a crucial role in closing 2024’s $60 billion acquisition of Pioneer Natural Resources, which made Exxon the top producer in the Permian Basin. The deal was Exxon’s largest since its merger with Mobil in 1998.
