UnitedHealth Group Incorporated

UnitedHealth Group Incorporated is an American health care and well-being company organized around two complementary businesses — UnitedHealthcare, which sells health benefits, and Optum, which sells care delivery, pharmacy, analytics and technology services back to the rest of the health system. Together they generated $447.6 billion of revenue in fiscal 2025, and the enterprise employed more than 390,000 people, nearly 165,000 of them clinical professionals.

This is a story about a company that mispriced its own risks and is now repricing everything. Through 2024 and 2025 UnitedHealth's medical costs rose faster than the premiums and government rates it had set to cover them; the medical care ratio climbed to 89.1% in fiscal 2025 from 85.5% a year earlier, and GAAP earnings from operations fell 41%, to $19.0 billion. Stephen Hemsley returned as chief executive in May 2025, replaced much of the leadership team, put the international assets up for sale, and reset benefits, networks and prices across Medicare Advantage, Medicaid and commercial. The question the file turns on is whether that repricing is a one-year catch-up or the start of a durable margin recovery — and whether Optum, the services engine that was supposed to carry the growth, can repair its own margins at the same time.

Second-quarter 2026 results, the freshest evidence, lean toward recovery: earnings from operations rose 55% year over year and the company lifted full-year adjusted earnings per share guidance to $19.50–$20. But commercial cost trend is still running above 11%, and management pushed the timetable for full commercial margin recovery past 2027. This is a report about a company winning the argument on cost control in government programs while still losing ground in commercial — and about what that mix is worth.
