Investors of Altimmune, Inc. Face Class Action Lawsuit News

Class Action Lawsuit Against Altimmune, Inc. Overview
Levi & Korsinsky, LLP has recently informed shareholders of Altimmune, Inc. ('Altimmune') about a class action lawsuit pertaining to alleged securities fraud. Investors are taking action to address their losses stemming from actions that occurred between August 10, 2023, and June 25, 2025.
Understanding the Class Definition
The lawsuit represents a collective effort from Altimmune investors adversely affected by the alleged deceptive practices. During this period, the company’s stock price was influenced by misleading statements, leading to significant financial impact on shareholders.
Key Details of the Case
On June 26, 2025, a critical press release revealed disappointing results from the company’s Phase 2b trial of Pemvidutide aimed at treating a specific type of liver disease. The released data did not meet the expectations set by the company leading up to the announcement. Although there were positive trends noted, the trial failed to achieve the necessary statistical significance. The higher-than-expected placebo response contributed to this disappointing outcome.
Market Response to the Trial Results
Following this news, the stock of Altimmune experienced a dramatic drop from $7.71 per share to $3.61 per share in a single day, marking a staggering decline of 53.2%. This significant loss prompted shareholders to seek legal recourse, initiating the class action lawsuit.
Next Steps for Affected Investors
Investors who experienced financial losses during the relevant period have until October 6, 2025, to request their appointment as lead plaintiff in this case. It’s important to note that participating in the recovery does not require one to serve as a lead plaintiff, allowing more investors to benefit from the lawsuit’s outcome.
