(WO) — Chevron has named Uriel “Ose” Oseguera as treasurer, effective Nov. 1, 2026, succeeding Navin Mahajan, who will retire after nearly 30 years with the company.
Oseguera currently serves as vice president of Upstream Business Performance & Finance. In his new role, he will oversee Chevron’s treasury organization, including capital markets, corporate finance, insurance, credit and risk management, reporting to Chief Financial Officer Eimear Bonner.
“Ose brings an exceptional combination of treasury expertise, global business leadership, and deep company knowledge to the Treasurer role,” Bonner said. “His experience across corporate finance, capital markets, and international business leadership provides a distinctive perspective on risk management, financial discipline, and value creation.”
Oseguera joined Chevron in 1990 and has held leadership positions in finance, treasury and planning across the U.S., Venezuela, Thailand, Indonesia and Australia. Before assuming his current upstream finance position, he served as general manager of Chevron’s Financial Shared Services organization.
Mahajan has served as Chevron’s treasurer since 2019 and held leadership positions spanning treasury, finance, compliance and business operations during his nearly three decades with the company.
“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.
