UnitedHealth Group Announces Surprise Exit of CEO Andrew Witty
UnitedHealth Group announced the surprise exit of CEO Andrew Witty on Tuesday and suspended its 2025 forecast due to surging medical costs, sending its shares down more than 10% premarket.
Former CEO Stephen Hemsley, who has been with the health care conglomerate for 28 years, is returning to the top role. Witty was leaving for personal reasons, the company said, without elaborating.
Challenges Faced by UnitedHealth Under Witty’s Leadership
Under Witty, UnitedHealth has met a series of challenges in the past year, including the murder of its top health insurance executive, Brian Thompson, last December.
Earlier in 2024, it was the target of a cyberattack at its tech unit that shut the U.S. health care processing system for days, affecting 200 million Americans.
Witty was also at the helm in April, when the company posted its first earnings miss since the 2008 financial crisis and lowered its annual outlook, citing higher-than-expected medical costs and “unanticipated changes” in its Optum business that impacted planned 2025 reimbursements.
Industry-Wide Challenges
The U.S. health insurance industry has been grappling with increased costs since mid-2023 due to a surge in demand for health care services under government-backed Medicare plans for older adults or individuals with disabilities.
Tuesday’s announcement also pulled down shares of other health insurers such as Humana, CVS and Elevance between 4% and 6%.
Reaction to Witty’s Exit
“The abruptness (of Witty’s exit) certainly is a surprise, but no one should be surprised given the unique struggles of UNH versus peers. At a certain point, leadership must be held accountable,” said Kevin Gade, chief operating officer at Bahl and Gaynor.
The guidance suspension wasn’t much of a surprise, said Gade. “As utilization spikes, you can assume improvement, stabilization or worsening on your forward guide. Unfortunately, in this environment, UNH expressed a worsening/spike in utilization of benefits, which is causing this suspension,” Gade said.
Other Developments
The company was also sued earlier this month for allegedly concealing how backlash from Thompson‘s killing was damaging its business.
