Investors Urged to Consider Legal Action Against Altimmune, Inc. Amid SEC Violations

Legal Implications for Altimmune, Inc. Shareholders

Altimmune, Inc. (NASDAQ: ALT) is currently embroiled in a legal conflict that raises significant concerns for its shareholders. The Gross Law Firm recently issued an important notice targeting investors of Altimmune, urging them to address potential claims stemming from the company's alleged violations of securities laws.

Background of the Lawsuit

According to the announcement made on September 15, 2025, shareholders who purchased ALT shares from August 10, 2023, to June 25, 2025, are particularly encouraged to contact the firm. They may have a chance to be appointed as lead plaintiffs in the class action lawsuit. Importantly, participation in this case does not require one to be a lead plaintiff, making it accessible for more shareholders to seek justice for their investments.

The complaint centers around a press release issued by Altimmune on June 26, 2025, which discussed the results from the IMPACT Phase 2b trial for Pemvidutide, a drug aimed at treating MASH (metabolic associated steatotic liver disease). While the company had previously assured shareholders of positive outcomes, the released findings showed that the drug did not meet the expected statistical significance regarding fibrosis reduction. This unexpected news led to an immediate and drastic drop in the company's stock price, falling from $7.71 to $3.61 in a single day—a staggering 53.2% decrease.

The Falling Stock Price

The significant fall in Altimmune's stock value has raised red flags among investors. The alarming decline occurred as shareholders were led to believe that the product would deliver promising results. Many feel misled by the company's inflated expectations prior to the trial results. The rise and fall in stock value illustrate the risky nature of investing in biotech firms, especially when trial outcomes don’t align with promises made by the management.

Next Steps for Altimmune Shareholders

Shareholders looking to act on their rights have an important deadline to keep in mind: October 6, 2025. This date marks the cutoff for those wishing to register as lead plaintiffs in the class action suit. It is vital for involved shareholders to act quickly, as registration ensures that they remain informed regarding updates and developments throughout the litigation process. Moreover, enrolling in this monitoring software offered by the Gross Law Firm allows shareholders to oversee their claims effectively.
