BRK.A is the stock ticker for Berkshire Hathaway’s higher-priced publicly traded share class.
Berkshire Hathaway’s Class A shares trade under the symbol BRK.A, while its more widely accessible Class B shares trade under BRK.B. Class A shares carry substantially greater voting power and represent 1,500 times the economic interest of a Class B share.
Warren Buffett transformed Berkshire from a struggling textile manufacturer into a diversified holding company. Its businesses and investments include insurance, railroads, utilities, manufacturing, and large positions in publicly traded companies.
The unusual share structure matters when comparing market-cap data. Market capitalization includes both share classes, so looking only at the price of BRK.A or BRK.B does not by itself reveal Berkshire’s total equity value.
