Deadline Alert: Planet Fitness, Inc. (PLNT) Shareholders Who Lost Money Urged To Contact Glancy Prongay Wolke & Rotter LLP About Securities Fraud Lawsuit

Planet Fitness faces a class action securities fraud lawsuit after the company slashed same-store sales growth guidance from 4-5% to 1% and withdrew its three-year growth plan in May 2026. The disclosure revealed that an over-pivoted marketing campaign failed to resonate with core customers and the company paused its Black Card price increase rollout. The stock fell 31.2% on the news. Investors who purchased PLNT securities between November 6, 2025 and May 6, 2026 have until September 14, 2026 to file a lead plaintiff motion.
