When the 2025 Fortune 500 was published a month ago, 55 companies on the list were led by female CEOs. Buck was one of the longer-tenured among that group; she’d led Hershey since 2017. She well outlasted the average tenure of a female Fortune 500 chief, which has hovered around four years for a decade. (For men, it’s seven—which Buck also beat.)

Wendy's CEO Kirk Tanner has been named the new chief executive of The Hershey Company. Tanner will replace Michele Buck, who is retiring after almost 20 years at Hershey, including almost eight as CEO. Tanner's move to Hershey marks his return to the consumer packaged goods space.
