Berkshire Hathaway Inc. (BRK-B) - Moat Analysis

Business Model

25%

3.6/5

3.62

The model combines contractual insurance premiums, long-lived regulated utility and rail revenues, and transactional manufacturing and retail, with most cash flow originating from FY2025 insurance revenue of $104B and industrial subsidiaries. Diversification across genuinely uncorrelated end markets is the standout structural feature. Geographic footprint is heavily US-weighted and most operating businesses are capital-intensive.

Forward visibility of revenue: backlog, contracts, retention

3.75

Summary

Insurance premium contracts, multi-year utility rate plans at BHE, and long-duration BNSF shipper contracts provide forward visibility across roughly half of revenue. Investment gains on the equity portfolio add volatility, driving the FY2023 revenue jump to $439B and FY2024 decline to $424B.

Summary

No reportable segment exceeded 28.3% of FY2025 revenue (Insurance $104B), with Manufacturing at $78B, Service and Retailing at $40B, BHE at $26B, and BNSF at $24B. The segments serve genuinely uncorrelated end markets (auto insurance, freight rail, utilities, industrial manufacturing, retail) alongside a $320B equity portfolio.

Distribution across regions and home-market dependence

Summary

The large majority of revenue originates in the United States, with BNSF operating exclusively in North America and GEICO serving only US auto policyholders. BHE owns UK and Canadian utility assets and some manufacturing subsidiaries export internationally, but combined non-US revenue remains a minority share.

Scalability20%

Ability to grow revenue without proportional cost increases

3.00

Summary

The holding structure adds little incremental overhead as subsidiaries scale, but the operating mix is dominated by capital-intensive businesses (freight rail, regulated utilities, heavy manufacturing) where incremental revenue requires proportional capex. Insurance float compounds without a linear cost driver, partially offsetting the capital intensity.

Revenue Quality25%

3.75

Nature of the revenue: contractual vs transactional, defensive vs discretionary

3.75

Summary

A meaningful share of FY2025 revenue is recurring and mission-critical: insurance premium renewals, regulated utility service, and long-tenor rail shipping contracts. Manufacturing and retail revenue is more transactional and discretionary, keeping the aggregate below subscription-software quality levels.

Competitive Advantages

40%

2.5/5

2.55

Berkshire's strengths lie outside the classical moat taxonomy. Pricing power is constrained in insurance, commodity manufacturing, and regulated utilities, with no aggregate premium brand. Switching costs are meaningful only at BNSF and BHE, covering roughly 13% of revenue. Network effects and innovation barriers are limited across the operating mix.
