Alignment Healthcare Faces Investor Investigation Over H3815 Star Rating Downgrade and CMS Bonus Eligibility

An ongoing investigation is examining disclosures made by Alignment Healthcare, Inc. (NASDAQ: ALHC) regarding its California HMO health plan contract (H3815) after federal regulators lowered its rating, affecting bonus payment eligibility.

Overview of the CMS Rating Downgrade

On October 8, 2026, Alignment Healthcare disclosed in an SEC filing that the Centers for Medicare & Medicaid Services (CMS) reduced the 2027 Star Rating for its H3815 contract from 4.0 to 3.5. This specific contract covers approximately 75% of the company's total health plan membership. According to the company's disclosures, the downgrade impacts quality bonus payments for fiscal year 2028, rendering the plan ineligible for those specific funds.

Following the disclosure, the company's stock price experienced a significant decline, dropping 13% to close at $7.55 on October 9, 2026, marking a 52-week low.

The recent market response follows a series of public statements and disclosures by company leadership:

• July 30, 2026: During an investor conference, CEO John Kao expressed confidence regarding the company's position on cut points and future bonus payments, though the remarks coincided with an approximate 20% drop in share price.
• September 15, 2026: At a Baird Healthcare conference, management declined to comment on final cut points and measure-level performance, contrasting with previous openness. This prompted another 20% decrease in share price.
