UnitedHealth Slashes 2025 Earnings Forecast by 24%, Shares Drop Amid Medicare Cost Surge

UnitedHealth Group (UNH) just knocked down expectations for its 2025 earnings, signaling that the company-and by extension, the health insurance industry-is still wrestling with surging medical costs, especially within Medicare Advantage plans. The stock reacted predictably, dipping over 3% in premarket trading.

The insurer forecasted adjusted earnings of about $16 per share for next year, well below the consensus estimate of $20.91. Revenue guidance skirted the $445.5 billion to $448 billion range, just shy of Wall Street's $449.16 billion estimate. Meanwhile, the market awaits 2026, when UnitedHealth anticipates bouncing back to earnings growth.

This follows a somewhat rocky path. Back in May, UnitedHealth hit pause on its 2025 outlook amid rising medical expenses, coupled with the unexpected exit of CEO Andrew Witty. Now, under new leadership-Stephen Hemsley taking the reins-the company faces a pile of challenges. They've got the weight of being the largest insurer along with the industry's proverbial bullseye on their back.

Medical costs, especially in Medicare Advantage, continue to outpace premiums. The projected medical loss ratio-basically the share of premiums paid out in claims-is expected to land between 89% and 89.5% in 2025. That's up significantly from 85.1% in Q2 last year and slightly above 89.3% analysts predicted for Q2 2025. This erosion in profitability is largely attributed to a spike in hospital visits, particularly for procedures delayed during the pandemic like joint replacements.

On top of that, Medicare funding cuts have added fuel to the fire, squeezing margins further.

Speaking of Q2, UnitedHealth posted adjusted earnings of $4.08 per share, missing analyst forecasts by 40 cents, while revenue hit $111.62 billion, coming in a hair above estimates. Net income dropped to $3.41 billion from $4.22 billion a year prior. Not exactly what shareholders hoped for, but the revenue boost was driven by strong growth in UnitedHealthcare and Optum, the company's care and pharmacy services arm.

Within Optum, revenue split into a bit of a mixed bag. Optum Rx, their pharmacy benefit manager, saw revenue jump nearly 19% to $38.46 billion. Meanwhile, Optum Health-which manages care services-shrunk 7% to $25.21 billion. This slide in care services revenue has raised eyebrows on Wall Street, with the company pledging to sharpen its focus on operational execution.

With Optum expecting annual revenue around $266 billion next year, it remains a massive profit center. But the pressure is mounting as regulatory scrutiny tightens. Notably, UnitedHealth is now cooperating with the Department of Justice over Medicare billing investigations, adding another layer of risk to the mix.

This earnings update comes against a backdrop of upheaval. The company's 2024 was heavy on drama: from the murder of UnitedHealthcare's CEO Brian Thompson, a massive cyberattack impacting millions, to sustained public and investor scrutiny. The shares have taken a beating, down more than 44% year-to-date.

So, what's next? UnitedHealth is clearly navigating some turbulent waters with medical costs and operational challenges. Whether the new leadership can steer the behemoth back to solid ground remains to be seen. Meanwhile, the healthcare insurance space is keeping a close eye on these Medicare Advantage cost trends that look far from calming down.
