UnitedHealth posts 6% higher profit, raises outlook for year UnitedHealth Group Inc. reported a 6% increase in second-quarter profit and raised its full-year outlook, but the nation's largest health insurer warned about a tough environment for its Medicare and Medicaid plans as governments face more financial strain. UnitedHealth Chief Executive Stephen Hemsley, in a conference call with analysts and investors, said that "there continues to be more downward than upward pressure across the healthcare landscape.... State budgets are clearly constrained for Medicaid. Industrywide, insurers have been pursuing more business through government health programs as commercial enrollment has slowed. The company's shares Thursday fell $1.36, or 2.4%, to $54.99. The Minnetonka, Minn., company said it earned $1.34 billion in the quarter, or $1.27 a share, compared with $1.27 billion, or $1.16, a year earlier. UnitedHealth said revenue in the quarter that ended June 30 grew 8% to $27.3 billion. The company is the first major health insurer to report second-quarter results, and it's considered an industry bellwether as rivals such as WellPoint Inc. and Aetna Inc. report later this month. UnitedHealth boosted its full-year profit estimate to a range of $4.90 to $5 a share, up from $4.80 to $4.95. Analysts said they were encouraged by UnitedHealth's outlook for medical cost trends to remain stable. The company said it expects a modest rise in costs in the second half of this year. Patients cutting back on medical care and elective procedures during a weak economy has helped boost the bottom line for many insurers in recent quarters.
