Adjusted earnings of $4.69 a share beat forecasts by 55 cents and the insurer lifted its 2026 target to at least $20.50. Its medical cost ratio improved to 88.4%, helped by $610 million of favorable reserve development, as revenue slipped from a year ago.
UnitedHealth Group cleared every bar it was set on Tuesday. Investors still ended up roughly where they started.
The largest U.S. health insurer reported third-quarter adjusted earnings of $4.69 a share, up from $2.92 a year earlier and above the $4.14 analysts had expected, according to LSEG. It raised its full-year adjusted earnings outlook to at least $20.50 a share, from $19.50 to $20.00. Analysts had forecast $19.86.
The shares opened at $397.63, about 5% above Monday's close, and touched $399.86. By about 1:45 p.m. Eastern they were down 0.3% at $377.41.
How the margin came back
The improvement came from costs rather than sales. Revenue was $112.7 billion, slightly below $113.2 billion a year earlier. Earnings from operations rose to $6.6 billion from $4.3 billion.
The medical care ratio, the share of premiums spent on patient care, fell to 88.4% from 89.9% a year earlier. The company credited medical cost management, benefit design changes and pricing. It also disclosed $610 million of favorable prior-period reserve development, meaning claims for earlier months in 2026 came in lower than it had set aside.
The operating cost ratio improved to 12.8% from 13.5%.
"Our third quarter results reflect the discipline and execution our teams are bringing to every part of our business," Chief Executive Stephen Hemsley said.
The segments
UnitedHealthcare, the insurance arm, served 48.3 million people, down from 50.1 million a year earlier, and generated revenue of $86.3 billion and earnings of $2.8 billion.
Optum Health, the care-delivery business, shrank by design. Revenue fell 10% to $22.9 billion as the company pulled back from markets where it lacked enough value-based care patients, but operating earnings rose to $735 million from $41 million.
Chief Financial Officer Wayne DeVeydt said in a television interview that investments in value-based care and artificial intelligence should have a compounding effect on medical cost management into 2027. He also said the independent dispute resolution process adds at least 1 percentage point to medical costs.
The intraday reversal
No single development explains the reversal. The gain faded during a session in which several companies that beat forecasts gave back early advances, and healthcare was the largest drag on the S&P 500, led by Johnson & Johnson. A fund tracking health-care providers, ticker IHF, reached its highest level since September 2024 in the morning and gave the gain back by afternoon.
Market implications
One reading is that the turnaround is now visible in the numbers. Operating earnings rose by half, the cost ratio fell 1.5 points, Optum Health's margin recovered and the company raised guidance above forecasts.
A second reading is that the quality of the beat needs checking. Revenue declined, membership shrank by more than 1.8 million, and $610 million of reserve releases helped the cost ratio in a quarter that beat estimates by about 55 cents a share.
What to watch
Results from other large insurers in the coming weeks will show whether lower cost ratios are an industry trend or specific to UnitedHealth's repricing.
