UnitedHealth Group Credit Ratings Affirmed Amid Improved Operating Trends
UnitedHealth Group's credit ratings have been affirmed by AM Best as stable outlooks, despite a weaker 2025 performance due to medical cost pressures. The affirmation reflects stronger operating trends in 2026, with improved margins and reduced risks.
The company's second-quarter 2026 operating margin rose to 4.6% from 2.4% the previous year, leading to a lower full-year medical care ratio outlook and higher earnings guidance. Optum, UnitedHealth Group's health services business, saw consolidated operating earnings increase by 19% in H1 2026.
The rating agency cited strong balance sheet strength, operating performance, and favorable business profile as reasons for the affirmation. However, AM Best noted that medical expenses in Medicare Advantage, broader medical cost inflation, and government program funding challenges continue to weigh on results.
