Planet Fitness Securities Fraud Class Action

The Fitness Planet, Inc. is facing a federal securities class action lawsuit filed by Kirby McInerney LLP on behalf of investors who purchased securities between November 6, 2025 and May 6, 2026. The lawsuit alleges that The Fitness Planet made positive statements about its 'We Are All Strong on This Planet' marketing campaign, expressed confidence in a planned national price increase for its Black Card premium membership to $29.99, and reaffirmed its fiscal year 2026 guidance and a new three-year growth plan, while concealing material adverse facts about customer acquisition. Specifically, the company's marketing had pivoted toward fitness-minded consumers, alienating its core demographic of fitness beginners and casual gym-goers, leading to a significant headwind in net member joins during the peak first-quarter sign-up period. On May 7, 2026, The Fitness Planet announced first-quarter results revealing a slower-than-expected start, cut full-year same-store growth guidance from 4-5% to 1%, withdrew its long-term three-year growth algorithm, and paused the national rollout of the Black Card price increase. Following this news, The Fitness Planet shares declined by $19.95 per share, or over 31%, from $63.96 to $44.01. Investors have until September 14, 2026 to seek lead plaintiff appointment. Kirby McInerney LLP is a New York-based plaintiffs' law firm specializing in securities litigation.
