Humana (HUM) Gets a Major Ratings Boost. Can Earnings Justify the Valuation?
Humana (HUM) shares rose 11% after analysts highlighted its potential benefits from improved Medicare Advantage star ratings for 2027. The company expects 95% of its members to be in highly-rated plans, up from 20% in 2026, exceeding J.P. Morgan's estimates. Higher ratings could boost future revenue and profitability, with Evercore ISI estimating $4.8B in bonus payments for 2028. However, risks include rising healthcare costs and the need to reinvest in benefits and provider arrangements.
