Overview
Berkshire Hathaway is a diversified holding company anchored by large insurance operations that generate substantial float, a major North American freight railroad (BNSF), and regulated utilities and energy infrastructure (Berkshire Hathaway Energy). Its most durable advantages are financial (float-funded investing and capital strength), physical-network barriers (rail and infrastructure), and regulated or franchise protections in utility service territories. The remaining operating businesses span industrial, building and consumer manufacturing, service businesses, retailing, fuel and travel centers, and wholesale distribution; their moats tend to be more business-specific and generally less structural than the core insurance, rail, and utility platforms. Key counter-pressures are insurance-cycle volatility and catastrophe risk, regulatory and political risk in utilities and rail, and competitive intensity across most non-regulated operating businesses.
