UnitedHealth is reeling from a roughly 20% stock rout after warning investors it expects its first annual revenue decline in more than three decades, a stunning reversal for a company long seen as one of Wall Street’s most reliable growth engines. The selloff wiped tens of billions of dollars off the health-care giant’s market value and sent shockwaves through the broader managed-care sector as investors reassessed the risks in the once‑high‑flying Medicare Advantage business.
UnitedHealth’s collapse accelerated after the company paired its fourth-quarter and full-year 2025 results with a 2026 outlook that calls for revenue of “greater than” $439 billion, roughly a 2% drop from last year and well below analyst expectations of around $454 billion. It would mark the first time since the late 1980s that the company’s annual revenue has contracted, underscoring how a mix of regulatory pressure, divestitures, and shrinking membership is reshaping the country’s largest health insurer.
