Which company’s stock-market ticker is BRK.A, representing its Class A shares?

Berkshire Hathaway’s Class A shares trade under the stock-market ticker BRK.A.

Berkshire Hathaway is a diversified holding company led for decades by Warren Buffett. Its businesses include insurance operations, railroads, utilities, energy, manufacturing, retail, and significant investments in publicly traded companies. The company’s insurance foundation includes GEICO and General Re.

Berkshire’s Class A shares are famous for their exceptionally high per-share price. The company introduced Class B shares in 1996, giving investors a more accessible alternative. Each Class B share represents a smaller economic interest and voting power than a Class A share, and the two classes trade under BRK.B and BRK.A respectively.

Berkshire’s market capitalization is calculated from both share classes. A high share price alone does not make it the largest company; market capitalization depends on the share price multiplied by shares outstanding. This distinction is important when comparing Berkshire with technology giants.
