Healthcare · Profile from Healthcare Research Companion
UnitedHealth Group Incorporated
The largest healthcare company in the world by revenue. It began in 1977 as a Minnesota HMO manager and grew into a vertically integrated giant that combines the biggest US health insurer (UnitedHealthcare) with Optum, a services empire that employs or affiliates tens of thousands of physicians, runs one of the three dominant pharmacy benefit managers and owns much of the plumbing of US healthcare payments. For two decades it was the model of disciplined managed-care growth. Between 2024 and 2026 it became the industry's lightning rod: the Change Healthcare cyberattack, the killing of UnitedHealthcare's CEO, a Medicare Advantage cost crisis, a CEO change and federal investigations.
