Exxon Mobil Corp.’s Liam M. Mallon, the company’s vice president and president of upstream, will retire after 34 years of service, effective Feb. 1, 2025.
The board has appointed Dan L. Ammann, currently Exxon’s low carbon solutions president, to assume Mallon’s roles, according to Exxon’s Dec. 3 press release.
Mallon, who has been Exxon’s upstream president since 2022, joined the company in 1990 in Aberdeen, Scotland, Exxon said. He later oversaw Exxon’s global upstream operations in Nigeria, Australia, Canada, Malaysia and Texas.
Exxon’s upstream results exceeded ambitious targets since helping to put together an upstream strategy in 2018, Mallon told Hart Energy recently. The company plans to continue to extend its upstream portfolio and improve recovery in the Permian Basin going forward, he said.

The board also named Barry L. Engle to succeed Ammann as president of low carbon solutions and vice president, effective Jan. 1, 2025.
Ammann joined Exxon in 2022 as president of low carbon solutions with a focus on delivering profitable, large-scale emissions-reduction solutions for key industries, Exxon said.
He served previously as CEO of Cruise, which is majority-owned by General Motors (GM), in 2018 and was appointed president of GM in 2014.
Engle joined Exxon in September 2024 with three decades of experience in the automotive industry, including General Motors where he was president of GM North America and GM International.
“These appointments continue the company’s approach of leveraging the diverse skills and experiences of a very accomplished executive team to bring fresh perspectives and approaches to each of our exceptionally talented organizations,” said Exxon Mobil CEO Darren Woods.
“We thank Liam for his long-standing, dedicated service to the company, and we wish him all the best in his well-deserved retirement.”
