UnitedHealth, the largest U.S. health insurer, reported a better-than-expected quarterly profit due to strength in its pharmacy benefit management business, and technology and consulting divisions.
The company's shares rose about 2.3 percent in light premarket trading on Tuesday.
UnitedHealth also narrowed its adjusted full-year profit outlook to $7.80 to $7.95 per share, from a prior range of $7.75 to $7.95 per share.
Revenue from the company's Optum business, which manages drug benefits and offers healthcare data analytics services, rose 51.5 percent to $20.6 billion for the quarter.
UnitedHealth which also sells employer-based insurance as well as Medicare, Medicaid and Obamacare health plans, is the only large insurer not involved in one of the major consolidation deals under review by anti-trust regulators.
In April, the company confirmed it would largely exit the Obamacare market in 2017, as it was expecting mounting losses from the program.
