UnitedHealth Group (NYSE: UNH) announced a major leadership transition as Stephen J. Hemsley returns as Chief Executive Officer, effective immediately. The move comes after Andrew Witty stepped down for personal reasons. Hemsley, who led the company from 2006 to 2017, will also retain his position as Chairman of the Board. Witty will continue to support the organization as a senior adviser.
The company also suspended its 2025 financial outlook, citing higher-than-expected medical expenditures. Accelerated care activity and elevated costs related to newly enrolled Medicare Advantage members are driving the revision. UnitedHealth now anticipates a return to its long-term 13% to 16% growth target in 2026.
Lead independent director Michele Hooper stated, “Steve Hemsley brings a combination of strategic vision and deep operational focus that are highly valuable to our company.”
