Planet Fitness faces securities fraud class action as investors invited to serve as lead plaintiff
Executive summary: Rosen Law Firm filed a securities fraud class action on behalf of Planet Fitness shareholders for purchases made between November 6, 2025 and May 6, 2026, claiming the company overstated marketing success and concealed pricing issues.

Likely next: Shareholders must file motions to serve as lead plaintiff by September 14, 2026; thereafter the court will appoint a lead plaintiff and the case will proceed to discovery and possible settlement or trial.
