Berkshire Hathaway is identified by the stock ticker BRK.A and is known for having one of the world's highest-priced shares.
Berkshire Hathaway's Class A shares have never undergone a conventional stock split, so the per-share price has risen to an unusually high level over decades. The company also offers lower-priced Class B shares, created in 1996 to make Berkshire ownership more accessible to smaller investors.
Warren Buffett has led Berkshire since 1965, transforming it from a struggling textile manufacturer into a diversified holding company. Its businesses include insurance, railroads, utilities, energy, manufacturing, and consumer brands, while its investment portfolio owns stakes in major public companies.
Share price is not the same as market capitalization. A company can have a high per-share price but a smaller total value than a company with a lower price and many more shares outstanding.
