As of Q4'25, UnitedHealth Group ( UNH ) reported a revenue surprise of -0.49%, indicating that actual revenue came in slightly below analyst expectations for the latest quarter. Year-over-year revenue growth for the same period stood at 12.31%, reflecting a robust expansion compared to the prior year. From Q1'23 to Q4'25, the revenue surprise percentage for UNH has shown considerable volatility, peaking at 10.66% in Q2'23 before trending downward and oscillating around zero, with several quarters of minor negative surprises in 2024 and 2025. In contrast, revenue growth (YoY) remained strong throughout the period, with double-digit increases in most quarters, though it dipped to a low of 6.41% in Q2'24 before rebounding to above 12% by the end of 2025. This suggests that while UNH consistently grew its revenue base, it faced increasing challenges in exceeding market expectations in recent quarters.
