As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: Defendants made false and/or misleading statements, as well as failed to disclose material facts, regarding the distinction between the Nanobodies and monoclonal antibodies, including that: (1) that SLK and BIMZELX share the same molecular targets (the inflammatory cytokines IL-17A and IL-17F); (2) that SLK's distinct Nanobody structure would not confer a superior clinical benefit over the traditional monoclonal structure of BIMZELX; (3) SLK's distinct Nanobody structure supposed increased tissue penetration would not translate to clinical efficacy; and (4) based on the foregoing, Defendants lacked a reasonable basis for their positive statements regarding SLK's purported superiority to monoclonal antibodies.
On September 28, 2025, MoonLake announced week-16 results from its Phase 3 VELA program. The results showed that SLK failed to demonstrate competitive efficacy relative to BIMZELX.
Following the announcement, MoonLake's stock price plummeted, falling $55.75 per share, or 89.9%, to close at $6.24 on September 29, 2025.

Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not.
