Lead Plaintiff Opportunity in Altimmune, Inc. Securities Fraud Case

Opportunity for Altimmune Investors to Join Class Action Lawsuit

Investors who purchased securities in Altimmune, Inc. (NASDAQ: ALT) between August 10, 2023, and June 25, 2025, are reminded of a pressing opportunity to lead a class action lawsuit against the firm. This legal action comes as a response to allegations of securities fraud that may have affected the investments of numerous stakeholders. The deadline to become a lead plaintiff for this case is set for October 6, 2025.

Understanding the Securities Fraud Allegations

The lawsuit initiated by the Rosen Law Firm, a highly regarded global advocate for investor rights, outlines that the defendants allegedly misrepresented critical information regarding the results of Altimmune's IMPACT Phase 2b MASH trial. Throughout the Class Period, there were claims that the firm had reliable data about the trial's outcomes. However, it appears that Altimmune did not achieve key statistical significance regarding the primary endpoint related to fibrosis reduction, raising red flags for many investors.

Altimmune had a history of promoting optimistic expectations regarding the trial results. They seemingly downplayed concerning details about higher responses from the placebo group that were likely to adversely affect the topline results. When this crucial information was finally disclosed to the public, it surfaced that the expectations set by the company were not grounded in reality. This led to significant losses for investors once the truth became apparent in the market.

Steps for Interested Investors

Investors who believe they may be entitled to compensation without fronting any costs can join the class action by visiting Rosen Law's website or by contacting Phillip Kim, a lawyer at the firm, at 866-767-3653 or via email at [email protected]. The firm operates on a contingency fee basis, meaning that clients will not have to pay legal fees unless a settlement is reached. This presents a reduced financial risk for investors looking to take legal action.
