Which company operates the NYSE-listed Class A shares under the ticker BRK.A?

Berkshire Hathaway operates its NYSE-listed Class A shares under the ticker BRK.A.

Berkshire Hathaway is a diversified holding company led for decades by Warren Buffett. Its businesses include insurance, freight rail, utilities, energy, manufacturing, retail, and a large portfolio of publicly traded investments. The company’s insurance operations, especially GEICO and reinsurance businesses, have historically supplied capital for acquisitions and investments.

Berkshire’s Class A shares are famous for their unusually high price because the company has never carried out a conventional stock split. It also offers lower-priced Class B shares, created in 1996 to make Berkshire ownership more accessible. The two classes represent different economic interests and voting rights.

Berkshire Hathaway is not simply an investment fund. It owns operating companies and holds securities, so its market value reflects both its businesses and investor expectations about management, capital allocation, and future earnings.
