Which company uses the Class A ticker BRK.A and is led by Warren Buffett?

Berkshire Hathaway uses the Class A ticker BRK.A and is led by Warren Buffett.

Berkshire Hathaway is a diversified holding company whose businesses include insurance, railroads, utilities, energy, manufacturing, and consumer brands. Warren Buffett has served as its chairman and chief executive since 1965, helping transform it from a struggling textile manufacturer into one of the world’s best-known investment groups.

The Class A shares, traded under BRK.A, are famous for their exceptionally high per-share price and for not having undergone a conventional stock split. Berkshire also issues Class B shares under BRK.B, which have different voting rights and a much lower price per share.

A high share price is not the same as a high market capitalization. Market cap depends on both price and the number of shares outstanding. Berkshire’s market value places it among the world’s largest companies even though its share-price structure is unusual.
