UnitedHealth Group named Wayne S. DeVeydt as chief financial officer, effective 2 Sept. 2025, succeeding long-time finance head John F. Rex. Rex, who has led the insurer’s finances since 2016, will shift to a strategic adviser role to Chief Executive Officer Stephen J. Hemsley. DeVeydt, 55, joins from Bain Capital and previously served as CFO of rival Elevance Health (then Anthem) from 2007 to 2016. His appointment adds external financial and operating experience as UnitedHealth seeks to sharpen cost controls and restore investor confidence. The move extends a leadership reshuffle at the nation’s largest health insurer following Hemsley’s return to the CEO post in May after Andrew Witty’s departure. UnitedHealth has been grappling with elevated medical expenses across the industry and faces pressure to improve performance amid recent management turbulence.
