Which company did Warren Buffett lead as chairman and CEO for decades?

Berkshire Hathaway was led by Warren Buffett as chairman and CEO for decades.

Buffett began buying shares in the struggling textile company Berkshire Hathaway in the 1960s. After taking control, he shifted the business away from textiles and built a diversified holding company through acquisitions and long-term investments.

Berkshire owns or has owned businesses in insurance, rail transport, utilities, energy, manufacturing, retail, and services. Its insurance operations, especially GEICO and reinsurance businesses, provide an important source of capital for investments. The company also holds large public-company stock positions.

Berkshire is not a conventional technology company, even though its market capitalization has made it one of the world's largest public businesses. Charlie Munger served as Buffett's longtime business partner and vice chairman until his death in 2023. Buffett announced Greg Abel as his successor as chief executive.
