UnitedHealth’s Stock Is Ailing. A Bigger Business Hasn’t Helped.

UnitedHealth UNH -0.19%  Group dominates the U.S. healthcare system, and it keeps getting bigger. But the company’s market value is trending in the opposite direction.UnitedHealth’s revenue grew nearly 8% in 2024, while its insurance arm gained 2.1 million U.S. customers. Over the last five months, though, the company has shed nearly $200 billion in market value.

Shares fell 27% over two days after the company slashed its full-year earnings guidance by more than 10% in mid-April. It was the third straight quarterly report from the company that was met with a substantial selloff in the stock.
