Minnetonka-based UnitedHealth Group reported a slightly smaller profit for the first quarter as investment income fell and enrollment declined, but the results still exceeded analyst expectations.
Nevertheless, Chief Executive Stephen Hemsley warned that the nation's biggest health insurer is likely to be hurt further this year as employers who offer health coverage continue to cut workers in a bad economy.
"We continue to be appropriately circumspect about the economic environment and the impact it may have on our businesses," Hemsley said in a call with analysts early Tuesday.
UnitedHealth stock fell $1.41, or 5.8 percent, to close at $22.80.
The company said investment and other income fell 43 percent to $158 million because of the volatile financial markets.
Earnings fell to $984 million from $994 million in the first quarter of last year. However, because the company has been buying back shares, earnings per share rose to 81 cents from 78 cents.
Revenue rose 8.4 percent to $22 billion, from $20.3 billion, because of growth in senior coverage and government plans and acquisitions.
The share of premiums paid out to cover medical claims stayed flat at 82.4 percent.
