COMPLAINT ALLEGATION SUMMARY:
The complaint alleges that, throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material facts about the company’s business, operations, and prospects. Specifically, Defendants misrepresented and/or failed to disclose that: (1) ImmunityBio’s claim that Anktiva is a cancer vaccine was false; (2) ImmunityBio’s Executive Chairman and Global Scientific and Medical Officer materially overstated Anktiva’s capabilities; and (3) as a result of the foregoing, Defendants’ positive statements about the company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.

WHY DID IMMUNITYBIO’S STOCK DROP?
On March 24, 2026, Bloomberg reported that ImmunityBio had receive a Warning Letter from the FDA stating that the company’s Executive Chairman and Global Chief Scientific and Medical Officer, Patrick Soon-Shiong, made inaccurate claims on a podcast regarding ImmunityBio’s lead biologic product, Anktiva, including that the drug “can cure and even prevent all cancer.” The FDA thus “determined that the TV ad and podcast [for Anktiva] are false or misleading” and “make the distribution of the drug in violation of the Federal Food, Drug, and Cosmetic Act.”

On this news, ImmunityBio’s stock price fell $1.98 per share, or 21.12%, to close at $7.42 per share on March 24, 2026. 

THE LEAD PLAINTIFF PROCESS: 
The Private Securities Litigation Reform Act of 1995 permits any investor who purchased or acquired ImmunityBio securities during the Class Period to seek appointment as lead plaintiff in the ImmunityBio class action lawsuit. A lead plaintiff is a representative party that acts on behalf of other class members in directing the litigation. In order to be appointed lead plaintiff, the Court must determine that the class member’s claim is typical of the claims of other class members, and that the class member will adequately represent the class. Your ability to share in any recovery is not, however, affected by the decision whether or not to serve as a lead plaintiff. Filling out the online form above or communicating with any counsel is not necessary to participate or share in any recovery achieved in this case. Any member of the purported class may move the court to serve as a lead plaintiff through counsel of his/her choice, or may choose to do nothing and remain an inactive class member.
