Membership grew by 48,500 to 284,800, and analysts raised full-year earnings estimates. Higher Star Ratings across all plans for 2026 could boost future reimbursement.

Multiple Law Firms Launch Investigations Following the whistleblower lawsuit, law firms Block & Leviton, Hagens Berman, Kaplan Fox, and Bragar Eagel & Squire announced investigations into Alignment for potential securities law violations. These investigations could lead to lawsuits and further pressure the stock as legal costs and uncertainty rise.
These investigations amplify the negative impact and keep the issue in the spotlight, affecting investor sentiment.
