Why is Chevron Reorganising its Senior Leadership Team?

Chevron has unveiled a major restructuring of its executive leadership, confirming the retirement of three senior figures and appointing their replacements predominantly from within the organisation over the next several months.

The transition could signal a shift in direction for the US energy giant, affecting key areas including business development, supply, trading and strategic planning.

The leadership overhaul coincides with the integration of Hess Corporation, a leading global independent energy company Chevron acquired in July 2025. 

A number of executives who have been overseeing and managing this integration process will now transition into permanent positions within the company.

Business development sees generational shift

Frank Mount, Chevron’s President of Corporate Business Development, will depart in November following a 33-year tenure. 

Since 2023, Frank has overseen the company's global business development operations, including negotiating and finalising the Hess acquisition.

"Throughout his career, Frank has contributed significantly to the success of Chevron," says Chairman and CEO Mike Wirth. "I am grateful for his years of service and dedication."

Jake Spiering, who currently serves as Director of Investor Relations, will take over from Frank on 1 August 2026. 

Since joining in 2008, Jake has occupied various finance leadership positions spanning Chevron's international asset base. Prior to Chevron, he gained experience in consulting at EY.

The appointment of Jake, aged 43, could indicate a move towards installing a younger generation of leaders in the business development function.

Strategy chief moves to trading

Patricia Leigh, President of Supply & Trading, will step down in July 2026 after 35 years with Chevron. 

Patricia assumed her present position in 2024, directing the company's approach to supply, logistics and trading during a period of significant market turbulence.

"Patti's deep expertise in many aspects of our business enabled her to shape Supply & Trading with strategic and commercial insight," Mike says. "She has had a significant positive impact on the organisation and its people."

Molly Laegeler, currently serving as Chevron's Chief Strategy Officer, will replace Patricia in March 2026. 

Molly became part of Chevron in 2005 and has previously managed operations at critical assets, including sites in the Permian Basin.

Her transfer from the strategy function to supply and trading will bring her closer to operational aspects of the business. 

Kevin Lyon, currently managing the Hess integration effort, will step into Molly's position as Chief Strategy Officer on 1 March 2026. 

Kevin joined Chevron in 1988 and has directed major projects spanning the US, Europe, Africa, Southeast Asia and Central Asia.

In the new role, his responsibilities will include shaping the company's primary strategies, optimising the enterprise portfolio and advancing sustainability programmes.

Shale operations see leadership change

Bruce Niemeyer, President of Shale & Tight, will retire in October following 26 years with Chevron. 

The company's Shale & Tight operation concentrates on fossil fuel resources located within rock formations, requiring specialised extraction techniques such as fracking and horizontal drilling.

After joining in 2000, Bruce has managed upstream operations throughout North America and led exploration and production activities for the company's Americas regions.

"Bruce has led with vision, character and a deep appreciation for the people at the heart of the work," says Mike. "He leaves a legacy of strong leadership and proven results."

Bruce will continue in an advisory capacity as Senior Executive Advisor until his October departure.

Gerbert Schoonman, currently Senior Executive Advisor for the Hess integration, will succeed Bruce in April 2026. 

Gerbert was among the Hess leadership team that remained with the organisation after the July 2025 merger. He brings over 35 years of experience in the oil and gas sector, with specialist knowledge in asset management, production operations and efficiency enhancement.

Jeanine Wai will assume the position of Director of Investor Relations on 1 April 2026. 

Following an earlier period at Chevron that concluded in 2007, Jeanine gained experience at Citigroup, JPMorgan and TotalEnergies before returning to the company in January 2026.

Her move back to Chevron after working in financial services could reflect the organisation's aim to enhance its engagement with investors during a transitional phase.

These leadership transitions will take place progressively throughout the coming year, concluding in November 2026 with Frank Mount's formal departure. The phased approach could allow for effective knowledge transfer whilst preserving operational stability.
