The Abel Era Begins: Berkshire Hathaway Resumes Buybacks, Rewires Leadership, and Sits on $373B in Dry Powder

Greg Abel's first 10 weeks as CEO have been anything but quiet. Buybacks are back, Todd Combs is gone to JPMorgan, and Abel just pledged his entire after-tax salary to Berkshire stock — all while the conglomerate's $373 billion cash pile waits for its first major deployment under new management.

S&P 500 Position

Berkshire is classified in the Financials sector but operates nothing like its neighbors. JPMorgan Chase (~$700B market cap), Visa, and Mastercard are the next-largest financials, but Berkshire's conglomerate structure makes sector comparisons nearly meaningless. It's functionally a GDP proxy — a diversified bet on the U.S. economy — competing with the S&P 500 index itself more than any single peer. Its $1.076 trillion market cap places it among the largest U.S. companies, well ahead of traditional financial peers but below the mega-cap tech cohort.

Company Overview

Berkshire Hathaway is in the middle of its most consequential leadership transition in six decades. Greg Abel officially took the CEO chair on January 1, 2026, after Warren Buffett's surprise retirement announcement in May 2025. Buffett remains chairman and, by Abel's account, is still in the Omaha office five days a week. But the symbolic shift is unmistakable: Abel signed Berkshire's 2025 annual report as CEO on February 28, published his first shareholder letter, and within days, recommenced share buybacks — the first since 2024. He then went on CNBC and announced he would use his entire after-tax salary (~$15.3 million) to buy Berkshire stock every year he serves as CEO. The transition comes with real structural changes. Todd Combs — Buffett's investing lieutenant and GEICO CEO — departed for JPMorgan in January 2026 to run a new $10 billion strategic investment group. Nancy Pierce, GEICO's COO, replaced him. CFO Marc Hamburg is retiring in mid-2027, with Berkshire Hathaway Energy's Charles Chang stepping in. Michael O'Sullivan, formerly Snap's general counsel, joined as Berkshire's first-ever general counsel. Meanwhile, Abel now directly oversees both the equity portfolio and all non-insurance operations. Ted Weschler continues to manage roughly 6% of the public stock portfolio. The financial backdrop is mixed. Full-year 2025 operating earnings came in at $44.5 billion — down 6% year-over-year — dragged by a 54% Q4 drop in insurance underwriting profits and a 25% decline in insurance investment income. Berkshire took $8.3 billion in impairments on Kraft Heinz and Occidental Petroleum. The cash hoard slipped slightly to $373.3 billion from a record $381.6 billion. The market's reaction to Abel's first annual letter was a 4.9% single-day drop, followed by a partial recovery after the buyback announcement. The stock sits roughly flat YoY, underperforming the S&P 500.

Products & Revenue

Berkshire's $371 billion revenue machine runs on seven reportable segments spanning insurance, energy, freight rail, manufacturing, distribution, and retail. The insurance group — GEICO, General Re, BHRG, and the Primary Group — generates the most revenue at ~28% of the total but its real value is the $176 billion float pool that funds the conglomerate's investments. Manufacturing businesses (Precision Castparts, Marmon, Iscar, etc.) contribute ~21%, while McLane and Pilot Travel Centers collectively represent the high-revenue, low-margin distribution layer at ~25% combined. BNSF Railway, despite being only ~6% of revenue, delivers outsized operating earnings. The equity portfolio (Apple, American Express, Coca-Cola, Chevron, five Japanese trading houses) generates investment income and capital gains that are not captured in operating revenue but remain central to Berkshire's value proposition.

Insurance Group (GEICO, General Re, BHRG, Primary Group) (~28%): Underwriting and investment income across auto (GEICO), reinsurance (General Re, BHRG), and specialty lines. Generates ~$176B in float — effectively zero-cost capital for Berkshire's investment operations.

Manufacturing Businesses (~21%): Precision Castparts (aerospace parts), Marmon (industrial products), IMC/Iscar (cutting tools), Lubrizol (specialty chemicals), and others. Revenue rose 1.6% in FY2025 to $78.5B.

McLane Company (~14%): Wholesale distribution of grocery and non-food products to convenience stores, restaurants, and retailers. High-volume, thin-margin business generating ~$51B in revenue.

Pilot Travel Centers (~11%): Largest operator of travel centers and truck stops in North America. Revenue declined 10% in FY2025 to $42.2B, largely due to lower fuel prices.

Service and Retailing Businesses (~12%): NetJets (fractional jet ownership), FlightSafety (pilot training), Dairy Queen, See's Candies, furniture retailers, and auto dealerships. Revenue grew nearly 7% in FY2025 to $42.7B.

Berkshire Hathaway Energy (~7%): Regulated utilities (PacifiCorp, MidAmerican Energy), natural gas pipelines, and renewable energy. Heavily investing in grid infrastructure for AI data centers. Revenue ~$26.3B.

BNSF Railway (~6%): One of North America's largest Class I railroads. Revenue ~$23.5B was flat YoY, but operating efficiency improved through employee productivity gains and lower fuel costs.

Based on FY2025 10-K filing (period ending December 31, 2025), released February 28, 2026. Revenue percentages are approximate based on segment disclosures.

Leadership

Greg Abel

CEO since 2026. Canadian-born accountant who joined Berkshire in 2000 when the conglomerate acquired MidAmerican Energy, where he eventually became CEO in 2008. He oversaw MidAmerican's transformation into Berkshire Hathaway Energy, one of North America's largest regulated utility groups. Named vice chairman of all non-insurance operations in 2018, he was appointed CEO effective January 1, 2026, with a $25 million salary — a significant increase from Buffett's symbolic $100,000.

Ted Weschler, Investment Manager: Now the sole portfolio manager after Todd Combs's departure. Manages approximately 6% of Berkshire's ~$300B+ public equity portfolio. His hedge fund Peninsula Capital had a stronger pre-Berkshire track record than Combs's Castle Point, and he's expected to remain long-term.

Ajit Jain, Vice Chairman, Insurance Operations: Oversees Berkshire's entire insurance empire — GEICO, General Re, BHRG, and the Primary Group — which produces $176 billion in float. Has been with Berkshire since 1986 and is considered one of the greatest underwriters in insurance history.

Nancy Pierce, CEO, GEICO: Replaced Todd Combs as GEICO CEO in January 2026, promoted from COO. Leading GEICO's push into commercial auto insurance and AI-driven telematics through the DriveEasy Pro program.

Adam Johnson, CEO, NetJets & President, Consumer Products/Services/Retailing: Given an expanded role in December 2025 to oversee Berkshire's consumer products, services, and retailing businesses while continuing to lead NetJets. A signal that Abel is consolidating operational reporting lines.

Michael O'Sullivan, Senior VP & General Counsel: Berkshire's first-ever general counsel, joining January 2026 from Snap. Previously a partner at Munger, Tolles & Olson — the firm co-founded by Charlie Munger. His hiring signals a more professionalized legal structure as Berkshire navigates post-Buffett governance.

The AI Angle

Powering the AI revolution, not building it

Berkshire Hathaway's AI strategy operates on two distinct layers: enabling AI infrastructure through its energy subsidiary and deploying AI operationally across its insurance and industrial businesses. The most consequential play is Berkshire Hathaway Energy's positioning as a critical power supplier for AI data centers. As hyperscalers face massive electricity demand, BHE's regulated utility footprint — spanning wind, solar, natural gas, and transmission — makes it a foundational enabler of the AI buildout. BHE's renewable energy subsidiaries have expanded a partnership with Uptake Technologies for AI-driven predictive maintenance on wind turbine fleets, improving annual energy production by up to 2%. This dual role — using AI internally while selling power to the AI ecosystem — is BHE's defining strategic position. At GEICO, AI adoption has accelerated after years of falling behind Progressive on telematics. GEICO partnered with Tractable AI for computer-vision-based vehicle damage assessment, allowing roughly 60% of auto claims to be settled remotely via photos. It deployed CCC Intelligent Solutions' Smart Red Flag Detection for AI-powered cross-carrier fraud detection. In late 2025, GEICO launched the DriveEasy Pro program with Motive, integrating AI dashcams, electronic logging devices, and behavior-based coaching into commercial fleet insurance — offering up to 10% premium discounts for policyholders who share telematics data. GEICO's virtual assistant Kate handles over 1 million customer inquiries monthly. The AI push contributed to GEICO's dramatic turnaround from a $1.9 billion underwriting loss in 2022 to a $3.6 billion profit in 2023, though it reversed course with a 54% Q4 2025 decline in underwriting profits. Berkshire's public equity portfolio provides indirect AI exposure: approximately 23-24% of its ~$300B+ stock portfolio is concentrated in Apple, Alphabet, and Amazon — all major AI platform companies. Berkshire initiated its Alphabet position in Q3 2025, a direct bet on Google's AI-search integration and cloud infrastructure. BNSF Railway is exploring precision railroading techniques and operational AI to improve fuel efficiency and employee productivity, while Berkshire Hathaway Specialty Insurance is hiring dedicated AI leadership (VP of Emerging Technology) to move from tactical adoption to strategic ownership. The risk is execution speed. Berkshire's decentralized model means there is no central AI mandate, no chief AI officer, and no conglomerate-wide data strategy. Each subsidiary adopts AI independently. While this avoids top-down boondoggles, it also means Berkshire may leave cross-subsidiary data synergies — the kind that could power superior underwriting models or predictive maintenance across BNSF and BHE — permanently on the table. Warren Buffett has compared AI to nuclear weapons in terms of societal risk, and the company's public AI posture remains cautious even as its subsidiaries quietly modernize.

Financial Snapshot

Revenue (TTM): $371.4B — TTM (period ending Dec 31, 2025) | Net Income: $67.0B net income (GAAP); $44.5B operating earnings

Margins: Gross ~25%, net ~18%. Operating margins vary dramatically by segment — insurance underwriting swings from losses to 10%+ margins, BNSF runs ~30% operating margins, McLane/Pilot operate at razor-thin ~2%.

Berkshire's balance sheet is a fortress. The 0.19 debt-to-equity ratio is effectively unheard of at this scale. The $373 billion cash pile — larger than the GDP of most countries — represents both Berkshire's greatest asset and its greatest challenge. Abel's first capital allocation test will define the post-Buffett era. Full-year 2025 operating earnings declined 6%, driven by insurance headwinds and FX losses at BHE, though manufacturing, services, and retailing segments showed modest growth. The $8.3 billion impairment on Kraft Heinz and Occidental signals a willingness to mark down legacy positions.

1-Year Performance

$498.98 (BRK-B), up 0.23% YoY — essentially flat, significantly lagging the broader S&P 500.

The stock hit its 52-week high in early May 2025, right before Buffett's surprise retirement announcement triggered a selloff reflecting the 'Buffett premium' being unwound. Shares bottomed in August at $455 — a ~16% drawdown from the peak — before recovering on the back of Q3 operating earnings strength. The February 28, 2026 earnings report drove a 4.9% single-day drop on disappointing Q4 results and a lack of cash deployment clarity, but Abel's buyback resumption and personal stock purchase announcement partially stabilized sentiment. Year-to-date, BRK-B is outperforming the S&P 500 as investors rotate into defensive names amid macro uncertainty.

Recent News

Fun Fact: Berkshire Hathaway has never held a quarterly earnings conference call — and under Greg Abel, it still won't. Abel explicitly reaffirmed Berkshire's policy of annual-only CEO communications in his first shareholder letter, making it the largest U.S. company by revenue to refuse quarterly analyst calls. The entire corporate headquarters in Omaha operates with fewer than 30 employees managing a $1 trillion enterprise, and until Michael O'Sullivan's appointment in January 2026, Berkshire had never employed a general counsel in its 60-year history under Buffett.
