Company: Chevron 
Title: Chief Financial Officer
Industry: Energy 

Standout achievement in 2025: Guided Chevron through major strategic and financial milestones, including the oil and gas company's $55 billion Hess acquisition. 

As the role of the modern CFO evolves, Bonner's impact at Chevron has gone well beyond the traditional finance role.

When Chevron closed its $55 billion acquisition of Hess in July 2025 — one of the larger M&A deals completed last year — Bonner drove the roadmap that integrated Hess's assets, technology, and talent. She also leveraged AI and advanced analytics to sharpen insights and enforce spending discipline, enabling Chevron to raise cost-reduction targets to $3 billion-$4 billion by the end of 2026.

Bonner also helped guide a company-wide reorganization, setting new financial targets while managing cost and capital plans.
