This lawsuit seeks to recover damages against Defendants for alleged violations of the federal securities laws on behalf of all persons and entities that purchased or otherwise acquired Planet Fitness, Inc. securities between November 6, 2025, and May 6, 2026, both dates inclusive (the “Class Period”).

Planet Fitness, Inc. Case Details

The Complaint alleges that, throughout the Class Period, Defendants made materially false and misleading statements and/or failed to disclose that:

  1. Planet Fitness’ updated marketing messaging was failing to resonate with, and was actively intimidating, its core target demographic of fitness beginners and casual gym-goers;
  2. as a result, the Company was experiencing significant headwinds in net member growth during its critical first-quarter sign-up period, rendering its previously issued fiscal 2026 guidance and long-term financial targets unattainable;
  3. contrary to Defendants’ representations, Planet Fitness would be required to restructure its marketing strategy, forgoing the benefits it claimed would result from continuing its existing marketing campaign, and abandon its planned Black Card membership price increase upon which its sales projections were based; and
  4. as a result of the foregoing, Defendants’ statements about the Company’s business, operations, financial guidance, and prospects were materially false and misleading at all relevant times.
