Abel was named vice chairman of Berkshire Hathaway in 2018. Although he has been at the company for more than two decades, he is considered to be much more guarded and hands-on than Buffett.

Abel, a small child when Buffett took the helm at Berkshire Hathaway, runs the conglomerate’s noninsurance businesses.

When Warren Buffett announced at his annual shareholder meeting that he is stepping down as CEO of Berkshire Hathaway at the end of the year, he elevated a 62-year-old Canadian executive named Greg Abel who has long been one of his top lieutenants.
