Planet Fitness Faces Securities Fraud Class Action Lawsuit

A securities fraud class action lawsuit has been filed against Planet Fitness, Inc. by the law firm Wolf Haldenstein Adler Freeman & Herz LLP. The suit is on behalf of investors who purchased or acquired the company's common stock between November 6, 2025, and May 6, 2026.

The complaint alleges that defendants made materially false and misleading statements and failed to disclose adverse information about the company's business prospects. Specifically, the suit claims Planet Fitness could not sustain membership growth without significant marketing changes and could not implement a planned price increase for its Black Card membership, which was crucial for its financial guidance.

On May 7, 2026, Planet Fitness announced its first-quarter 2026 financial results. The company lowered its same-store growth forecast from 4-5% to 1% and withdrew its previously issued three-year growth outlook. Factors cited included a marketing campaign that failed to resonate with customers and increased competition. The company also paused its planned national rollout of the Black Card price increase to focus on revitalizing new membership growth.

Following this announcement, Planet Fitness's stock price dropped by $19.95, or 31.2%, closing at $44.01 per share on May 7, 2026. Investors who purchased shares during the specified period and incurred losses are encouraged to contact Wolf Haldenstein by the lead plaintiff deadline of September 14, 2026.
