What this company does

AI

Berkshire Hathaway is a holding company that owns insurance operations (GEICO, reinsurance), the BNSF railroad, utilities and energy businesses, manufacturing and retail subsidiaries, plus a massive portfolio of stocks and Treasury bills. It earns money primarily from insurance premiums and investment income, product sales across its industrial and consumer subsidiaries, and freight rail and utility revenues. The company sits on a record $377 billion in cash and Treasuries as of September 2025, up sharply from year-end, signaling continued caution on deploying capital into equities.

Key risks

AI
  • Massive cash drag: $377B in cash and Treasury bills (~31% of assets) earning short-term yields signals limited attractive deployment opportunities.
  • Equity portfolio concentration: $283B in equity securities creates significant mark-to-market earnings volatility — investment gains swung 9M YoY from $46B to $22B.
  • Equity method losses of $4.3B in first nine months 2025 versus $967M gain prior year, indicating deterioration in Kraft Heinz/Occidental-type holdings.
