Who are Berkshire Hathaway's decision-makers?

Greg Abel became President and CEO on January 1, 2026, after Warren Buffett's announcement at the May 2025 annual meeting. Abel, born in Edmonton, Alberta, Canada in 1962, spent his career in energy: he joined geothermal producer CalEnergy in 1992, rose through MidAmerican Energy, and became CEO of what is now Berkshire Hathaway Energy (BHE) in 2008. Under his leadership BHE became one of the largest US renewable energy operators, generating roughly 10% of all US wind power. He joined Berkshire's board in 2018 when Buffett appointed him Vice Chairman for Non-Insurance Operations — effectively a six-year CEO apprenticeship.

Warren Buffett, born August 30, 1930 in Omaha, remains Executive Chairman. Ajit Jain joined Berkshire in 1986 and has overseen insurance operations for nearly four decades, building the float-driven model that underpins Berkshire's capital advantage. Ted Weschler manages a portion of the $300+ billion equity portfolio following Todd Combs's December 2025 departure to lead JPMorgan's new $10 billion Strategic Investment Group. Nancy Pierce succeeded Combs as GEICO CEO.

At the 2026 annual meeting — his first as sole CEO — Abel told shareholders 'we're going to be a builder of technology, not just a buyer of technology,' and introduced BRK Tech, a San Francisco-based internal technology organization tasked with accelerating AI and digital transformation across all subsidiaries. Abel has emphasized cultural continuity with Buffett's decentralized model while signaling that the record cash reserve will be deployed decisively when valuations are appropriate.

At the Berkshire holding company level, Greg Abel has final authority over capital allocation — acquisitions, major investments, and dividend policy. The ~25-person Omaha HQ does not purchase enterprise software, industrial equipment, or technology platforms centrally. For any transaction at the subsidiary level, the relevant subsidiary CEO holds full P&L authority.

All procurement happens at the subsidiary level. GEICO's CTO and CFO own insurance technology, telematics, and underwriting systems purchasing. BNSF's CIO oversees rail operations, logistics software, and the new in-house AI predictive maintenance initiative. BHE's leadership controls utility infrastructure, grid modernization contracts, and renewable energy technology. Clayton Homes runs its own manufacturing and mortgage technology stack. For a vendor or partner, the actionable buying committee is almost always at the subsidiary — not at Berkshire HQ. BRK Tech, however, represents a new potential centralized entry point for AI platform and digital transformation vendors seeking to sell across multiple subsidiaries simultaneously.

Berkshire operates the most radical decentralization of any Fortune 5 company. The holding company owns subsidiaries and allocates excess capital, but mandates almost nothing operationally. Each subsidiary maintains its own brand, culture, compensation structure, and vendor relationships. This model has historically attracted owner-operators who sell their businesses to Berkshire specifically to preserve autonomy — a key part of the acquisition pitch.

Under Greg Abel, the structure is being modestly formalized. BRK Tech — headquartered in San Francisco and announced in 2026 — is designed to help subsidiaries evolve from technology buyers into technology builders. It identifies common design patterns, builds reusable reference architectures, and deploys shared intellectual property across the portfolio. Subsidiaries retain the right to adopt or decline BRK Tech offerings. The energy business (BHE) is investing heavily in grid modernization to support AI data center demand, and BNSF is deploying in-house AI for predictive maintenance. Abel has signaled he will deploy Berkshire's record cash reserve into large acquisitions, which may bring additional subsidiary and technology diversity.
