ImmunityBio Inc. shares fell 5.05% and hit a 5-day low amid ongoing legal troubles.
The company is facing a class action lawsuit initiated by Hagens Berman on behalf of investors who purchased ImmunityBio securities between January 19 and March 24, 2026. This follows an FDA warning letter citing misleading claims about Anktiva, which previously caused a significant drop in share price and investor confidence. The lawsuit alleges that ImmunityBio made false statements regarding Anktiva's capabilities, leading to substantial investor losses.
This legal action could further complicate ImmunityBio's financial situation and reputation, especially as it seeks to recover from the fallout of the FDA's warning and regain investor trust.
