Berkshire Hathaway, led for decades by Warren Buffett, is known for owning Berkshire Hathaway Energy and GEICO.
Berkshire Hathaway is a diversified holding company rather than a single-industry corporation. Its businesses include insurance, rail transportation through BNSF Railway, energy and utilities, manufacturing, retail, and other operating subsidiaries. GEICO is one of its best-known insurance businesses.
Warren Buffett became chairman and chief executive after acquiring control of the struggling textile company in the 1960s. He and Charlie Munger transformed it into an investment and operating conglomerate by emphasizing disciplined capital allocation and long-term ownership.
Berkshire’s market capitalization is unusual because its share price is extremely high and it has historically avoided stock splits for its Class A shares. That high price does not alone determine its market value; the total number of shares and overall valuation matter.
