Berkshire Hathaway is the investment conglomerate led by Warren Buffett.
Buffett became associated with Berkshire after buying shares in the struggling textile company in the 1960s. He eventually redirected the business toward insurance and investments, transforming it into a diversified holding company.
Berkshire owns or invests in businesses across insurance, railroads, utilities, manufacturing, retail, and financial services. Its major wholly owned businesses include GEICO, BNSF Railway, and Berkshire Hathaway Energy.
Berkshire is often discussed differently from technology companies because it has historically emphasized operating businesses, long-term stock holdings, and insurance float. Its Class A shares are famous for their exceptionally high per-share price, while Class B shares provide a more accessible ownership option.
