UnitedHealth Stock Crashes 20% After Q1 2026 Earnings Miss and Medicare Rate Shock

# UnitedHealth Stock Crashes 20% After Q1 2026 Earnings Miss and Medicare Rate Shock

> **Quick answer:** UnitedHealth Group (UNH) stock plunged approximately 20% on April 21, 2026, after Q1 2026 earnings badly missed Wall Street's $6.48 per share consensus. The Medical Care Ratio — the key metric measuring how much of every premium dollar goes to medical claims — came in well above the expected 85.7%, signaling that healthcare cost inflation is accelerating rather than stabilizing. CEO Stephen Hemsley suspended 2026 guidance for the second consecutive quarter. UNH has now lost more than 54% of its value from its all-time high, making this one of the most dramatic collapses of a blue-chip Dow component in recent history.

UnitedHealth stock crash headlines dominated markets on the morning of April 21, 2026, as the company's first-quarter results delivered a brutal verdict: the turnaround story isn't holding. Shares fell roughly 20% at the open — erasing tens of billions in market capitalization in a matter of hours — and dragged the entire health insurance sector into the red alongside them.
