Chevron Announces Leadership Changes

HOUSTON, TX -- Chevron Corporation (NYSE: CVX) today announced the election of Uriel "Ose" Oseguera as Treasurer, effective November 1, 2026. Oseguera succeeds Navin Mahajan, who will retire from Chevron after nearly 30 years of service.

As Treasurer, Oseguera will lead Chevron's treasury organization, including capital markets, corporate finance, insurance, credit and risk management activities. He will report to Chevron Chief Financial Officer Eimear Bonner. Oseguera currently serves as Vice President, Upstream Business Performance & Finance.

“Ose brings an exceptional combination of treasury expertise, global business leadership, and deep company knowledge to the Treasurer role," said Bonner. “His experience across corporate finance, capital markets, and international business leadership provides a distinctive perspective on risk management, financial discipline, and value creation. Coupled with strong relationships across the enterprise and sound judgment, Ose is exceptionally well positioned to advance Chevron's strong financial position and long-term value.”

Oseguera joined Chevron in 1990. Over the course of his career, he has held leadership positions in finance, treasury and planning across Venezuela, Thailand, Indonesia, Australia, and the United States. Prior to his current role, he served as General Manager of Chevron's Financial Shared Services organization. Oseguera earned a bachelor's degree in business administration from California Polytechnic State University, San Luis Obispo, and an MBA from Saint Mary's College of California.

Mahajan has served as Chevron's Treasurer since 2019. During his career, he held leadership roles across treasury, finance, compliance, and business organizations globally.

"Throughout his nearly 30 years with Chevron, Navin has been a trusted leader whose expertise, integrity, and commitment have strengthened our company and Finance organization," Bonner said. "You could always count on Navin when the challenges were most complex and the stakes were highest. His rare combination of innovation, discipline, and thoughtful decision-making enabled him to navigate complexity, inspire teams and deliver lasting impact."
