Investors of Altimmune, Inc. Urged to Join Class Action Lawsuit Following Stock Price Plunge

In recent news, shareholders of Altimmune, Inc. (NASDAQ: ALT) who experienced financial losses are being encouraged to reach out to The Gross Law Firm regarding a pending class action lawsuit. The announcement comes in light of a steep decline in the stock price, following disappointing results from a critical clinical trial.

Class Action Notification

The Gross Law Firm has officially notified ALT shareholders about the opportunity to participate in this class action, which is centered around potential legal claims dating from August 10, 2023, to June 25, 2025. Anyone who acquired shares of Altimmune during this period may qualify to be part of the action, and it's vital for affected shareholders to act without delay. Registering as a shareholder to take part in this lawsuit not only secures the opportunity for recovery but also involves the provision of ongoing updates about the case's progress through an innovative portfolio monitoring software.

The Financial Impact of Recent Developments

On June 26, 2025, Altimmune shocked investors by announcing the topline results of the IMPACT Phase 2b MASH trial concerning Pemvidutide, a treatment aimed at metabolic dysfunction associated with non-alcoholic fatty liver disease. Despite the company's prior assurances of success and promising results, the release revealed a failure to achieve statistical significance regarding its primary endpoint, which was fibrosis reduction.

In detail, while the data from the trial indicated a positive trend in fibrosis improvement, the company's claims were thwarted by a greater-than-expected response from the placebo group. This led to a stark response from the market, with Altimmune's stock plummeting by over 53%—dropping from $7.71 to a mere $3.61 per share overnight. This drastic price drop has left many investors questioning the validity of their investment and the accuracy of the company’s public statements leading up to the trial results.

Next Steps for Shareholders

The deadline for shareholders interested in taking part in this class action lawsuit is set for October 6, 2025. This date marks the cutoff for anyone wishing to file as a lead plaintiff, although joining the action itself does not necessitate this role. Affected shareholders are highly encouraged to contact The Gross Law Firm through the provided links to formally register their claims.
