UnitedHealth Group Incorporated (NYSE:UNH) is the largest diversified healthcare company offering health insurance plans across employer-sponsored, Medicare Advantage, Medicaid, and individual markets, covering over 50 million people in the US. The company also owns the Optum segment, which provides pharmacy benefit management, healthcare delivery services, and complementary data analytics and technology solutions.

UnitedHealth Group Incorporated (NYSE:UNH) started 2025 with strong growth across businesses but faced unexpected performance challenges, leading to a downward revision in adjusted EPS outlook. The company identified two main factors impacting performance: increased care activity in Medicare Advantage, with Q1 2025 care activity increasing at twice the expected rate, and unanticipated changes in Optum Medicare membership profiles affecting 2025 revenue. The care activity increases were primarily in physician and outpatient services, specifically limited to the Medicare Advantage business and not affecting commercial or Medicaid businesses.

To address these challenges, UnitedHealth Group Incorporated (NYSE:UNH) is implementing several initiatives, including ensuring complex patients engage in clinical and value-based programs, consistently engaging with members in homes and post-discharge settings, and improving physician clinical workflow to better transition to the new CMS risk model. Despite these challenges, UNH’s Medicare Advantage business is still expected to serve an additional 800,000 people this year, while Optum Health is on track to add 650,000 net new patients to value-based care arrangements. UNH remains committed to returning to its long-term EPS growth target of 13% to 16%, making it one of the most profitable stocks to buy now.
