Likely next: Investors may file lead plaintiff motions by the September 14 deadline; if appointed, the case will advance to discovery, with possible settlement negotiations or trial thereafter.
Rosen Law Firm has issued a notice reminding shareholders who purchased Planet Fitness (PLNT) stock between November 6, 2025 and May 6, 2026 that they may move for lead plaintiff role by the September 14 deadline. The lawsuit alleges that the company made misleading disclosures about Black Card pricing, net member growth and same‑club sales guidance, which preceded a sharp stock decline after Planet Fitness lowered its 2026 targets and withdrew its three‑year growth algorithm. If a lead plaintiff is appointed, the case will proceed through discovery and potentially toward settlement or trial, exposing Planet Fitness to legal costs, possible financial penalties and heightened regulatory scrutiny.
