What Happened?
UnitedHealth (UNH) stock suffered a catastrophic collapse in 2025, plunging nearly 50% from over $600 per share to around $310-$320. This was a fundamental breakdown in the company’s core insurance business, driven by one metric that exploded: the Medical Care Ratio (MCR).
The damage came in two brutal phases. First, earnings got crushed. Then the valuation multiple collapsed. Together, they created a perfect storm that wiped out hundreds of billions in market value.
The MCR measures how much of the premium revenue is allocated to paying medical claims. For years, UnitedHealth kept this ratio stable at around 82%. But in 2025, it jumped to roughly 88%, with some quarters hitting 89.9%. That’s a 600-basis-point increase, eating directly into profits.
What caused it? Medicare Advantage members started using way more medical services than expected. Demand for outpatient and physician services surged far beyond what the company planned for when it set 2025 pricing. When you’re paying out that much more in claims while revenue growth can’t keep pace, profitability collapses.
In April, UnitedHealth shocked investors by slashing its 2025 adjusted earnings per share guidance from $29.50- $30.00 to $26.00- $26.50. Later in the year, the company pulled its annual outlook entirely, and CEO Andrew Witty stepped down for “personal reasons.”
By the time the dust settled, full-year 2025 EPS was tracking toward just $16.25, over $13 per share below the original guidance.

What the Market Is Telling Us About UNH Stock
UnitedHealth Group stock experienced a devastating market downturn driven by both declining earnings and a collapsed valuation multiple. The healthcare giant, which historically traded at a premium 24x earnings due to consistent double-digit growth, plummeted to just 18x by late 2025.
This created a compounding effect in which lower earnings were multiplied by a lower multiple, crushing the stock from both sides.
The catalyst was an MCR (Medical Cost Ratio) shock that destroyed the company’s earnings predictability. Wall Street stopped viewing UNH as a premium healthcare leader and began treating it like a lower-quality, higher-risk insurance business.
The selloff rippled across the entire health insurance sector, with competitors like Elevance, CVS Health, Cigna, Centene, and Humana dropping 3-13%, wiping out over $130 billion in market value in a single day.
Adding to the crisis, Optum—the high-growth segment that previously insulated UnitedHealth from insurance volatility—stumbled badly.
Medicare funding cuts, value-based care pressures, and heavy investment costs drove Optum’s operating earnings down from approximately $16.7 billion in 2024 to around $12.5-$12.8 billion in 2025. The company lost both its growth engine and profit buffer simultaneously.
Non-financial headwinds compounded the damage. The December 2024 murder of UnitedHealthcare CEO Brian Thompson sparked widespread public anger over claim denials and industry practices.
A massive February 2024 ransomware attack on Change Healthcare affected 190 million Americans, forcing UnitedHealth to provide over $9 billion in temporary funding.
Reports of a Justice Department probe into Medicare Advantage billing practices added further uncertainty.
Warren Buffett’s $1.6 billion stake announcement in August provided brief relief, sending shares up 12%, but fundamental concerns persisted.
Looking forward, new CFO Wayne DeVeydt projects cautious optimism. The company is pricing 2026 Medicare Advantage plans at a conservative 10% medical cost trend (up from 7.5%) and expects to lose about 1 million members as it exits unprofitable segments.
Recovery requires three catalysts: normalized medical utilization, successful execution of 2026 pricing, and Optum’s return to growth. Until then, UNH stock remains under pressure despite trading below historical averages.
