FDA Warning Letter: The FDA issued a warning to ImmunityBio regarding misleading efficacy claims made by its chairman, Dr. Soon-Shiong, about Anktiva, resulting in a 21% drop in share price on March 24, 2026, erasing nearly $2 billion in market capitalization and severely impacting investor confidence.
Class Action Initiated: Hagens Berman has launched a class action lawsuit on behalf of investors who purchased ImmunityBio securities between January 19 and March 24, 2026, alleging violations of federal securities laws and urging affected investors to submit their losses to support the investigation.
Efficacy Claims Controversy: Soon-Shiong claimed in a podcast that Anktiva could treat all cancers, while the FDA stated there is no evidence supporting such claims and that promotional materials failed to disclose Anktiva's full FDA-approved indications, raising public health concerns.
Investor Alert: Hagens Berman advises investors who suffered significant losses in ImmunityBio or possess information that could assist the investigation to contact the firm, ensuring their rights are protected in potential recovery efforts.

Reason

BTIG assumed coverage of ImmunityBio with a Buy rating and $13 price target. The stock has had a strong start to 2026, rising 318% year-to-date driven by 700% y/y growth for ANKTIVA in the US, EU conditional marketing approval, and approval for NSCLC in Saudi Arabia, and the firm believes further share appreciation from here will be led by continued ANKTIVA commercial execution and label expansion, the analyst tells investors in a research note.
