Rosen Law Firm Alerts Altimmune, Inc. Shareholders About Their Legal Rights and Class Action Lawsuit
On August 13, 2025, the Rosen Law Firm, a prominent global advocate for investor rights, announced that a shareholder has initiated a class action lawsuit against Altimmune, Inc. (NASDAQ: ALT). This lawsuit aims to represent purchasers of Altimmune securities made between August 10, 2023, and June 25, 2025. As an investor, if you purchased shares during this time frame, you might have qualifications to join the class action and play a role in rectifying any injustices faced.
The class action lawsuit is a significant step, especially for those who believe their investments have been impacted by misleading information released by the company. According to details from the Rosen Law Firm, essential expectations surrounding the results from Altimmune's IMPACT Phase 2b MASH trial were grossly overstated. Investors might remember the assurances that surrounded the trial's potential success, which were severely undermined when actual results revealed a lack of statistical significance concerning the fibrosis reduction primary endpoint.
The situation escalated due to the revelation that Altimmune's expectations regarding positive outcomes were inflated, while responses from the placebo group were notably higher than anticipated. The disparity between marketed expectations and actual results left many investors feeling misled and vulnerable to financial losses.
If you have an interest in potentially serving as a lead plaintiff, the Rosen Law Firm has stipulated that relevant actions must be taken by October 6, 2025, to ensure representation in this lawsuit. Engaging as a lead plaintiff means acting on behalf of fellow shareholders, guiding the litigation to seek justice for all parties involved.
Joining this class action is straightforward. Interested parties can visit Rosen Legal's submission page, call Phillip Kim, Esq. at 866-767-3653, or reach out via email at [email protected] for more detailed information regarding the process.
It's important to note that, as of now, a class has not yet been certified. Until such a certification occurs, individual investors are not represented unless they secure their preferred legal counsel. That said, individuals also have the option to remain absent from class participation and still retain their rights in potential recovery outcomes, should the case succeed in the future.
Given the financial climate and recent trends in securities litigation, it's crucial for investors to stay informed about their rights and options. Whether you plan to join the lawsuit or simply want to understand your rights regarding Altimmune’s securities, the Rosen Law Firm remains at the forefront of supporting the investor community.

This situation serves as a reminder of the significant role legal advocacy plays in protecting investor rights. As developments unfold, stakeholders are encouraged to remain vigilant and proactive in exploring their opportunities for recourse against any potential corporate infractions. This includes understanding the crucial deadlines involved and the implications of participation in class actions.
In conclusion, if you are an investor who purchased shares of Altimmune, Inc. during the specified period, you owe it to yourself to investigate whether you may have a valid claim in this ongoing class action lawsuit.
