UnitedHealth Group has announced a sudden leadership change, naming a new chief executive after Andrew Witty’s unexpected resignation. Witty stepped down from his role for unspecified “personal reasons,” leaving a significant gap in the company’s top leadership. To fill this vacancy, Stephen J. Hemsley, who had previously served as UnitedHealth’s CEO from 2006 to 2017, will return to lead the company. Along with returning to the CEO role, Hemsley will also remain the board chairman. Witty will continue with the company in a diminished capacity as a senior adviser to Hemsley.
UnitedHealth Faces Stock Decline, Legal Scrutiny, and Leadership Changes Amid Growing Industry Concerns
Andrew Witty’s resignation has come amid significant challenges for UnitedHealth Group. The company has faced criticism regarding the practices of the health insurance industry, and there have been growing concerns over the direction of the company’s operations. UnitedHealth’s stock has been on a downward trajectory, falling more than 17% on the day of the leadership announcement. This is a stark contrast to its previous high, which was $630.73 per share in November, with the stock now closing at $311.38. The company’s performance and leadership changes signal a period of uncertainty and potential restructuring.

UnitedHealth Group’s struggles are compounded by legal challenges, including a federal investigation into its business practices. The company’s stock woes and increased scrutiny come amid broader concerns over the health insurance industry. This investigation by the Justice Department adds to the company’s financial and operational troubles, highlighting issues that go beyond leadership shifts. The company’s handling of these challenges will likely be a key focus under Hemsley’s renewed leadership.
UnitedHealth Suspends 2025 Outlook Due to Unexpected Costs, CEO’s Tragic Death Precedes Leadership Change
In addition to the leadership change, UnitedHealth has also suspended its 2025 annual outlook. The suspension is due to unexpected financial difficulties, particularly related to the higher-than-expected medical costs for many Medicare Advantage beneficiaries. These costs have been higher than anticipated, adding to the company’s struggles. The suspension of the outlook reflects the company’s uncertainty as it tries to recalibrate its strategy and operations. However, UnitedHealth has expressed confidence in returning to growth by 2026.
A significant event leading up to the leadership change was the tragic shooting of Brian Thompson, the former CEO of UnitedHealthcare, in December. Thompson was fatally shot in midtown Manhattan in what authorities have described as a “premeditated, preplanned targeted attack” while he was on his way to an investors’ conference. The incident has attracted significant attention, and Luigi Mangione, 27, was arrested after a nationwide manhunt. Mangione faces both federal and state charges, including murder and terrorism, and if convicted, could face the death penalty.
