Investors Urged to Review Altimmune, Inc. Class Action Details

Class Action Lawsuit Overview
NEW YORK — Pomerantz LLP has announced that a class action lawsuit has been initiated against Altimmune, Inc. This lawsuit allows investors who have sustained losses related to their investment in Altimmune to take action regarding potential securities fraud or other unlawful business practices by the company.
Important Deadlines for Investors
If you have purchased or otherwise acquired Altimmune securities, it's essential to note that you have until October 6, 2025, to petition the Court to appoint you as the Lead Plaintiff in the class action. This is a critical opportunity for affected investors to make their voices heard.
Company and Market Response
The litigation revolves around whether Altimmune, along with certain of its officers or directors, has engaged in deceptive practices that violate securities laws. The specifics of this case emerged following disappointing results from clinical trials conducted by the company.
A Closer Look at the Recent Clinical Trials
On June 26, the company released the topline results from the IMPACT Phase 2b trial of Pemvidutide, aimed at treating MASH (Metabolic Associated Steatotic Liver Disease). Unfortunately, the results indicated that the Company not only failed to achieve the desired statistical significance regarding the fibrosis reduction they had anticipated but also showcased a higher-than-expected placebo response, leading to questions about the company's previous optimistic claims.
Stock Market Impact
Following this news, the stock price of Altimmune dropped significantly, falling $4.10 or approximately 53.2%, to close at $3.61 per share. This sharp decline reflects the market's concern regarding the company's future prospects and the validity of its previous assurances to investors.
