KEY TAKEAWAYS:   U.S. raises 2027 Medicare Advantage payment rates by 2.48% on average   Move expected to add more than $13 billion to insurer payments   Shares of UnitedHealth, CVS Health and Humana jump sharply   Rate increase eases pressure from rising medical costs and margin strain   Shares of U.S. health insurers gained in premarket trading on Tuesday after the government finalized Medicare Advantage payment rates above estimates, which are expected to add more than $13 billion in additional payments next year. Insurers had lost billions in market value after the Trump administration’s smaller-than-expected January proposal sparked backlash from an industry already grappling with significant financial strain. Shares of UnitedHealth jumped 6.6%, CVS Health  rose 7.3%, while Humana – which led as the best-performing stock on the SP 500 – surged 10.4%. Elevance Health, Centene and Molina Healthcare climbed between 3.3% and 5.3% before the bell. The Centers for Medicare Medicaid Services said late on Monday it would raise payments to private insurers offering Medicare Advantage plans to older adults in 2027 by 2.48% on average, much higher than the smaller-than-expected 0.09% rate increase that was proposed in January. “This improvement should allow the industry to expand margins in 2027 when coupled with benefit cuts,” said Mizuho analyst Ann Hynes. BETTER-THAN-FEARED RATES Investors had expected a rate increase of at least 1%, Wall Street analysts had said earlier. “This elevates the case for some margin growth in 2026 and lessens the growing perception that CMS‘ harsh policy stance on the group is worsening,” said Leerink analyst Whit Mayo. “At minimum, the sector will be perceived to be more investable.” Health insurers had argued the disappointing rates proposed in January did not reflect the reality of rising medical costs, which have been squeezing industry margins for nearly three years. “The industry has continued to face a tough environment, but on the heels of this more favorable release, we might be seeing the tide changing,” Oppenheimer analyst Michael Wiederhorn said. Insurers would also get a 2.5% benefit from a change to risk assessment payments related to health status, for a total increase of about 5%, a Medicare agency official said in a call with media. ...read more read less
