Warren Buffett began buying shares of beverage giant Coca-Cola (NYSE: KO) in 1988 through his holding company, Berkshire Hathaway (NYSE: BRK.A) (NYSE: BRK.B), which now owns more than 400 million shares. It has staged a robust comeback from pandemic declines, and sales increased 12% in the 2022 second fiscal quarter (ended July 1) on top of already strong numbers from last year. It's also highly profitable, although earnings per share decreased in the second quarter as a result of supply chain issues, increased costs, and global inflation.
