Alignment Healthcare Stock Drops Following CMS Star Rating Downgrade
Alignment Healthcare (ALHC) shares fell approximately 20% after CMS downgraded a key health plan contract rating. An investigation into potential securities law violations is underway.
Alignment Healthcare, Inc. (NASDAQ: ALHC) experienced a significant stock price decline of roughly 20% on October 9, 2026. The drop followed the Centers for Medicare & Medicaid Services (CMS) release of its 2027 Medicare Advantage Star Ratings, which lowered the company's California H3815 HMO contract rating to 3.5 stars from 4.0 stars. This contract serves over 75% of Alignment Healthcare's health plan members.
In the wake of the rating news, analysts at Bank of America and William Blair reportedly downgraded their price targets and adjusted their ratings. William Blair significantly cut its price target by more than 60%. The company is now subject to an investigation concerning potential securities law violations.
Alignment Healthcare had announced on October 8 that six of its seven eligible contracts received four stars or higher. However, the H3815 contract, which represents the majority of its membership, faced the downgrade.
Prior to these developments, CEO John E. Kao had expressed confidence in the company's standing during a July 30, 2026 earnings call, despite acknowledging a "shaky" regulatory environment surrounding star ratings. The company's stock also saw a dip on September 15, 2026, after Kao declined to comment on pending star rating decisions at a conference.
