Altimmune Investors Encouraged to Join Class Action Lawsuit After Significant Stock Drop

Class Action Alert for Altimmune, Inc. Investors

Investors who have suffered losses due to their investment in Altimmune, Inc. (NASDAQ: ALT) are being urged to join a class action lawsuit initiated by Levi & Korsinsky, LLP. The law firm seeks to recover losses incurred by shareholders between August 10, 2023, and June 25, 2025, as a result of alleged securities fraud.

Case Background

According to the lawsuit's specifics, significant issues arose when Altimmune released topline results from the IMPACT Phase 2b MASH trial. Despite previous communications that alluded to inflated expectations surrounding these results, the study failed to achieve statistical significance concerning its primary endpoint related to fibrosis reduction. While some improvements were detected, a troublesome placebo response countered these findings, leaving many investors bewildered.

On June 25, 2025, shares of Altimmune closed at $7.71, but the following day, stock prices plummeted to $3.61 - a staggering decline of 53.2%. This sharp drop brought immediate financial concern to investors who had believed in the company’s potential based on misleading information.
