UnitedHealth Group Inc. (UNH) suffered its worst trading day in over two decades on Thursday.
Company's shares plummeted more than 22% after missing first-quarter earnings expectations and sharply cut its 2025 profit outlook. The decline, which erased roughly $140 billion in market value, dragged the Dow Jones Industrial Average down 1.2% and sent tremors through the broader healthcare sector.
The health insurance behemoth reported adjusted earnings of $7.20 per share, falling short of the $7.29 anticipated by analysts, while revenue climbed to $109.6 billion—a 10% year-over-year increase but still under the $111.6 billion Wall Street forecasted.
More damaging, however, was UnitedHealth's slashed forecast for 2025 earnings. The company now expects adjusted earnings of $26 to $26.50 per share, down sharply from its prior guidance of $29.50 to $30 per share. It marks a rare and significant reset for a company that had beaten top-line expectations in 17 of the previous 18 quarters.
Medicare Advantage Woes at the Core
The dramatic revision was driven primarily by higher-than-expected medical utilization rates within the company’s Medicare Advantage business. Physician and outpatient services usage was nearly double the forecasted increase for the year, Chief Executive Officer Andrew Witty said. These pressures were isolated to the Medicare segment, with UnitedHealth’s commercial and Medicaid businesses unaffected.
The company also cited a weaker-than-expected performance in its OptumHealth segment, particularly due to membership changes tied to departing Medicare Advantage plans. Many new patients joining Optum came from plans exiting the market, leading to lower reimbursement rates and a more complex patient mix. Ongoing Medicare funding reductions under the Biden administration further compounded the problem.
The medical care ratio rose to 84.8% in Q1, missing expectations for the sixth consecutive quarter, and UnitedHealth now anticipates the metric to rise to as high as 87.5% in 2025—another indication of climbing medical costs that threaten profitability.
Fallout Across the Sector
UnitedHealth’s stumble sent ripple effects throughout the healthcare space. Peer insurers were hit hard: Humana (HUM) dropped over 8%, Elevance Health slid 5%, and CVS Health (CVS) lost 4%. The S&P 500 healthcare sector edged down despite a broader market rise.

Until this week, UnitedHealth had been one of the stronger performers in the space, rebounding 33% from its February lows after the DOJ announced an investigation into its billing practices. That momentum evaporated Thursday.
Despite the sharp decline, the company remains optimistic that the Medicare-related headwinds are “highly addressable,” with plans already underway to transition patients into value-based care models and better align with the new CMS risk adjustment system. Still, the company has effectively written off 2025 as a recovery year, focusing instead on long-term performance improvements heading into 2026.
Broader Implications
UnitedHealth’s earnings disappointment underscores broader pressures facing Medicare Advantage providers. Rising healthcare utilization and tighter reimbursement rates have created a challenging operating environment, exacerbated by regulatory shifts and demographic shifts in patient populations.
With healthcare spending in the U.S. rising 7.5% in 2023 to $4.9 trillion, insurers are struggling to control medical costs in a system stretched by complexity, aging populations, and inflationary pressures. UnitedHealth’s swift fall from earnings leader to sector laggard reflects how quickly the balance can shift.
Investors hoping for a quick rebound may be disappointed. With operational headwinds persisting and cost controls unlikely to deliver immediate relief, UnitedHealth’s massive sell-off could signal a revaluation of managed care expectations across the board.
