Levi & Korsinsky Reminds Planet Fitness Investors of the Pending Class Action Lawsuit With a Lead Plaintiff Deadline of September 14, 2026 - PLNT

Levi & Korsinsky, LLP notifies institutional investors in Planet Fitness, Inc. (NYSE: PLNT) that a securities class action has been filed on behalf of shareholders who purchased PLNT securities between November 6, 2025 and May 6, 2026.

The complaint asserts that Planet Fitness gave investors an overly positive picture of its ability to drive membership growth through its national marketing campaign and pricing strategy.

The action claims that the Company's peak first-quarter sign-up period was weaker than expected because its marketing messaging allegedly failed to resonate with core fitness beginners and casual gym-goers.

Planet Fitness also paused the planned national Black Card price increase and revised key 2026 targets.

As averred in the complaint, Planet Fitness previously projected 2026 system-wide same club sales growth in the 4% to 5% range, revenue growth of approximately 9%, adjusted EBITDA growth of approximately 10%, and adjusted diluted EPS growth of 9% to 10%. The Company later revised those expectations to approximately 1%, 7%, 6%, and 4%, respectively.

Shares fell approximately 31.19%, a decline of $19.95 per share, after Planet Fitness disclosed slower net member growth, reduced 2026 guidance, withdrew its three-year growth algorithm, and paused the planned Black Card price increase.

The complaint alleges Planet Fitness made materially false or misleading statements regarding the efficacy of its marketing strategy, its ability to achieve projected membership growth, its planned Black Card price increase, and its three-year growth algorithm during the Class.
