Who are Chevron's decision-makers?

Mike Wirth (Chairman & CEO) embodies Chevron's culture of home-grown leadership: he joined as a design engineer in 1982 and spent 36 years rising through downstream and chemicals, midstream, and global supply and trading before becoming CEO in February 2018. Under Wirth, Chevron has executed its most significant strategic pivot in decades — completing the $53 billion Hess acquisition, relocating headquarters to Houston, crossing 1 million BOE/day in the Permian, and launching first oil at Tengiz FGP — while maintaining a capital-return program that delivered a record $27 billion to shareholders in 2024 and committing to $10–$20 billion in annual buybacks through 2030.

Eimear Bonner (EVP & CFO) joined Chevron in 1998 and made history in 2021 as the company's first female Chief Technology Officer before her 2024 promotion to CFO, where she was named a 2026 CNBC Changemaker for guiding Chevron through the Hess integration. Her background spans Kazakhstan operations (General Director of Tengizchevroil LLP), strategy, and enterprise technology — giving her an unusually cross-functional perspective in the CFO role. Mark Nelson (Vice Chairman, EVP Oil, Products & Gas) is the operational backbone, overseeing the entire integrated value chain with 30+ years at Chevron covering retail, marketing, and business planning. T. Ryder Booth (VP Technology, Projects & Execution, effective July 1, 2025) oversees the company's technology strategy including enterprise AI, reflecting a deliberate elevation of digital capability as a competitive lever.

Procurement authority at Chevron is distributed across business units but governed by a strict capital allocation governance process. At the enterprise level, the CFO (Bonner) and her VP of Finance control capex allocation above defined thresholds; major contracts and strategic vendor relationships typically require sign-off at the SVP or EVP level.

For technology purchases, the VP Technology, Projects & Execution (Booth) and his VP-level reports own platform decisions (cloud, AI, data, enterprise software), while each Business Unit President controls operational-technology and oilfield-services vendor relationships. The New Energies business (Gustavson) has its own procurement budget (~$1.0–1.5 billion/year) for hydrogen, CCS, and renewables supply chain. For most enterprise SaaS and professional-services vendors, the effective buying committee is: the relevant Business Unit VP, the IT/digital team under Booth, and Finance (CFO organization for large multiyear commitments). Legal (Pate's organization) reviews all major vendor contracts.

Chevron runs a centralized global procurement function, and large contracts often require formal RFP processes and competitive bids — vendor relationships built at the VP or President level dramatically accelerate procurement timelines. The Hess integration (two large enterprise IT estates being merged through 2026–2027) is creating an active buying window for data integration, API management, and enterprise architecture advisory services.

Chevron operates through two primary reporting segments — Upstream (exploration and production) and Downstream (refining, marketing, chemicals) — plus a New Energies unit that sits adjacent to both. Following the 2025 Hess integration, the company is restructuring its upstream organizational layers to consolidate international offshore assets (U.S. Gulf, Nigeria, Angola, Eastern Mediterranean) into a single offshore business unit, reducing management layers and headcount by up to 20% by end-2026.

At the senior level, the Office of the CEO (Wirth), Vice Chairman (Nelson), CFO (Bonner), VP Technology (Booth), CLO (Pate), and New Energies President (Gustavson) form the de facto executive committee. Business Unit Presidents (Shale & Tight, Mid-Continent, International Upstream, etc.) report to Nelson and exercise significant P&L authority. The company also has a growing Houston-based corporate functions cluster following the 2024 HQ relocation, with the San Ramon campus retained for California-facing operations (~1,500 employees) and international hubs in Almaty (Kazakhstan), Perth (Australia), Lagos (Nigeria), London, and Singapore.
