Which company did Warren Buffett build into a major conglomerate and investment holding company?

Warren Buffett built Berkshire Hathaway into a major conglomerate and investment holding company.

Berkshire Hathaway began as a textile manufacturer, but Buffett and his investment partners gradually redirected it toward insurance, investments, and ownership of operating businesses. Buffett became chairman and chief executive in 1965 after acquiring control of the company.

Insurance is central to Berkshire’s structure because premiums provide investable funds, often called “float,” before claims are paid. The group also owns or controls businesses in areas such as freight rail, energy, manufacturing, retail, and consumer products.

Berkshire’s market value is unusual among giant public companies because it has historically avoided paying a regular dividend. Investors often study Buffett’s annual shareholder letters and the company’s large portfolio of publicly traded stocks when assessing its value.
