UNH 10-K Analysis: Why UnitedHealth's Medical Cost Crisis Is Worse Than Peers
UnitedHealth Group grew Medicare Advantage membership by 600,000 in FY2025 and revenue surpassed $447 billion. Operating income fell 41%. The FY2025 10-K reveals a medical cost ratio of 89.1% — the worst trajectory among five managed care peers we analyzed from raw filing data. UNH's +5.9 percentage point MCR deterioration is nearly double the peer average, exposing the vertical integration model as a cost amplifier, not a dampener.
