Oil and gas giant Chevron Corp. has announced several leadership changes, including moves within its executive team and strategy and business development units, according to a Sunday announcement.

Eimear Bonner, vice president and chief technology officer for Chevron, has been named as the next chief financial officer for the oil company. Bonner, who is also president of the Chevron Technical Center, will succeed Pierre Breber, who is retiring after 35 years with the company. The change will commence March 1, 2024, with Bonner reporting to Chairman and CEO Mike Wirth.

Bonner has held numerous roles with Chevron since joining the company in 1998. In her role as CTO, she leads the deployment of technology and digital solutions across the company. As president of Chevron’s Technical Center, Bonner leads the group that provides technical expertise and develops new technologies to support Chevron’s global operations and new energy businesses.

Previously, Bonner was general director of Chevron’s largest joint venture, Tengizchevroil (TCO), in Kazakhstan, where she managed its operational and financial performance. Before that, she was TCO’s general manager of operations.

With Bonner assuming the role of CFO, Chevron has also named Balaji Krishnamurthy as vice president of the Chevron Technical Center. Krishnamurthy, who joined Chevron in 2002, is currently Chevron’s vice president of strategy and sustainability. Prior to that, he was president of Chevron Canada.

Molly Laegeler, vice president of Chevron’s San Joaquin Valley Business Unit, will succeed Krishnamurthy as vice president of strategy and sustainability. Frank Mount, current vice president of M&A and origination, will become Chevron’s vice president of business development. 

Laegeler and Mount have been with Chevron since 2005 and 1993, respectively.

“We expect to continue to strengthen our performance with Balaji, Molly and Frank in their new roles,” Vice Chairman Mark Nelson said in the announcement. 

Chevron has also waived its directors’ mandatory retirement age of 65 for Wirth, who will turn 63 later this year.
