About this site
This site is a sourced biography of Gregory E. Abel, the Canadian-born executive who ran Berkshire Hathaway Energy and became Berkshire Hathaway’s CEO on January 1, 2026. It compares his documented acts with the public record of Warren Buffett and Charlie Munger. It is not a hostile case file and not a tribute.
Identity: Gregory E. Abel (also Greg Abel), director of Berkshire since 2018 and CEO from January 1, 2026 (2026 DEF 14A); born 1962 in Edmonton (Horatio Alger Association). This is not Gregory S. Abel of Maryland, the I AM ABEL Foundation, or Abel Speaks.
