Key executives running Berkshire Hathaway's $1 trillion empire
Greg Abel and Howard Buffett
Greg Abel, CEO
Buffett announced Abel's promotion at Berkshire's annual meeting, in May 2025. Many Berkshire managers describe the 64-year-old as knowledgeable and compassionate, with a capacity to listen.
Abel, known for his hands-on style, came into the Berkshire fold with its acquisition of MidAmerican Energy in 2000. He turned the unit, since renamed as Berkshire Hathaway Energy, into one of the largest power providers in central and western United States.
After helming that business as its CEO for a decade, Abel was appointed vice chairman in 2018 to oversee Berkshire's non-insurance businesses — railroad; chemical, energy and industrial companies; and businesses such as Fruit of the Loom and See's Candies.
He is believed to be a billionaire, selling his 1% stake in Berkshire Hathaway Energy to Berkshire for $870 million in 2022.
