BRK-A

Berkshire is a decentralized holding company (Item 1) spanning primary and reinsurance insurance, BNSF freight rail, a utilities/energy group, and a long tail of manufacturing, services and retail businesses run with "few centralized or integrated business functions." FY2025 financials are a fortress: stockholders' equity $717B (+10.5%), retained earnings $763B (+9.6%), liabilities/equity of just 0.70x, and operating cash flow surging +50.3% to $46.0B. Deloitte issued a clean opinion and management concluded internal control over financial reporting was effective as of 12/31/2025 — no red flags in the auditor or controls language.

The scary headline — net income down 24.8% to $67.0B — is largely an accounting artifact. GAAP forces Berkshire to run unrealized marks on its equity portfolio through earnings, which is why FY2022 printed a -$22.8B loss and FY2023 snapped back to $96.2B. That mark-to-market whipsaw, not operating deterioration, drives the swing. The steadier signal is cash: operating cash flow up ~50% and net margin still 27.1%. ROE of 9.3% is genuinely modest, but it is depressed by the sheer size of the equity and cash base rather than by weak businesses.
