Berkshire Hathaway Inc. New

Berkshire Hathaway operates dozens of wholly-owned businesses across insurance (GEICO, reinsurance), freight rail (BNSF Railway), utilities and energy (generation, transmission, pipelines), and manufacturing (everything from Dairy Queen restaurants to precision aerospace components) [Berkshire Hathaway website]. The company also manages a massive public stock portfolio, investing insurance premiums and operating cash in publicly traded companies like Apple and Alphabet. Think of it as both a holding company that owns and operates real businesses, and an investment firm that buys stakes in other companies.
