Rosen Law Firm Launches Securities Class Action Inquiry for Alvotech Shareholders

New York, January 17, 2026 — The Rosen Law Firm, a globally recognized plaintiffs’ law firm specializing in investor rights, is encouraging shareholders of Alvotech (NASDAQ: ALVO) to consider their legal options following concerns that the company may have issued materially misleading business information to the public.

What Is the Investigation About?

The securities class action inquiry stems from events tied to Alvotech’s disclosures regarding its regulatory application process. On November 2, 2025, Alvotech announced an update on its U.S. Biologics License Application (BLA) for its biosimilar product AVT05. In that announcement, the company revealed that the U.S. Food and Drug Administration (FDA) had issued a Complete Response Letter (CRL), indicating that certain manufacturing deficiencies needed correction before approval could be granted.

Following this news, Alvotech’s stock price reportedly declined sharply — falling around 34% on November 3, 2025 and nearly 4% on November 4, 2025 — which raised concerns among investors about the company’s public disclosures and transparency.

Who Can Participate?

If you purchased shares or other securities of Alvotech during the relevant period and suffered financial losses as a result, you may be eligible to participate in the prospective class action lawsuit. Participation does not require any out-of-pocket legal fees under the firm’s contingency fee arrangement, meaning legal fees are only collected if the case results in recovery.

To obtain information about joining the action, investors are directed to fill out a submission form on the Rosen Law Firm’s website or contact the firm directly via phone or email provided by the law firm.
