UnitedHealth Group announced on May 13, 2025, that CEO Andrew Witty is stepping down for unspecified “personal reasons,” with former CEO Stephen J. Hemsley resuming leadership, as reported by Reuters.
The sudden change, amid a turbulent year marked by the December 2024 killing of UnitedHealthcare CEO Brian Thompson, regulatory scrutiny, and a 17% stock drop, sees Hemsley, who led from 2006 to 2017, also retaining his board chairman role, while Witty transitions to a senior adviser position.
Witty’s exit, effective immediately, follows his tenure since 2021, during which UnitedHealth faced challenges, including a sharp market value decline from $630.73 in November 2024 to $311.38 on May 13, 2025. Hemsley’s return aims to stabilise the Dow Jones component, which suspended its 2025 financial outlook due to high Medicare Advantage costs and planned benefit expansions, projecting a growth recovery in 2026.

— UnitedHealth Group (@UnitedHealthGrp) May 13, 2025The leadership shift follows the December 2024 murder of Brian Thompson, UnitedHealthcare’s CEO, in a targeted Manhattan attack. Suspect Luigi Mangione, 27, faces terrorism and murder charges, pleading not guilty after a five-day manhunt. UnitedHealth also faces a Justice Department investigation into its practices, amid broader industry criticism, as noted by Bloomberg. The stock’s 17% plunge reflects investor concerns, debating the company’s stability and Hemsley’s ability to navigate ongoing challenges.
UnitedHealth has not announced plans for a permanent CEO replacement, focusing instead on Hemsley’s interim leadership. The suspension of the 2025 outlook, driven by unexpected medical costs, signals caution, though the company’s expansion of Medicare Advantage benefits aims to retain market share. X discussions highlight mixed sentiments, with some praising Hemsley’s experience and others questioning the lack of a long-term succession plan, underscoring the need for strategic clarity.
UnitedHealth unexpectedly suspended earnings guidance and brought back Chairman and former CEO Stephen Hemsley for the top role, saying Andrew Witty has resigned “for personal reasons.”
