Berkshire Hathaway BRK-A

Berkshire Hathaway Inc engages in a diverse range of business activities through its subsidiaries. The company operates primarily in insurance, rail transportation, energy, manufacturing, services, and retail. Its decentralized structure allows each business to operate independently while benefiting from strong capital allocation.

Revenue is generated from insurance premiums and investment returns, railroad freight charges, energy sales and services, manufactured goods, and retail product sales. Insurance underwriting collects premiums from policyholders and invests the float to earn interest and dividend income. BNSF earns revenue by transporting goods across its rail network, while BHE sells electricity and natural gas to utility and commercial customers.

The company operates through the following segments: Insurance underwriting, Insurance investment income, BNSF, Berkshire Hathaway Energy, Manufacturing, service and retailing, Investment gains and losses, and Other.

• Insurance underwriting: This segment writes property and casualty, life and health insurance policies through GEICO, BH Primary, and BHRG, collecting premiums and managing claim liabilities.
