Planet Fitness Sued Over Marketing and Price Increase Misrepresentations

Block & Leviton, a leading securities class action firm, has announced the filing of a securities fraud lawsuit against Planet Fitness, Inc. (NYSE: PLNT). The lawsuit alleges that the company misled investors during a specific period by overstating the success of its marketing campaign and the potential for its Black Card price increase, while also failing to disclose the negative impact of its marketing strategy on new member sign-ups.

According to the complaint, Planet Fitness had assured investors that its "We Are All Strong on This Planet" campaign was resonating and had the potential to extend into 2026. The company also expressed confidence in a planned national Black Card price increase to $29.99 and reaffirmed its FY2026 guidance and a new three-year growth plan. However, the lawsuit claims that the company concealed the fact that its marketing had alienated its core customer base, leading to a decline in new member sign-ups.

On May 7, 2026, Planet Fitness issued a significant update, slashing its same-store sales growth guidance from 4-5% to approximately 1%, withdrawing its three-year growth targets, and pausing the Black Card price increase. The company also acknowledged that its marketing had "pivoted too far" and was alienating core customers. This news caused the company's stock to drop by about 31% in a single day, from $63.96 to $44.01, resulting in substantial losses for investors.

The lawsuit is open to anyone who purchased Planet Fitness, Inc. common stock between November 6, 2025, and May 6, 2026, and has seen their shares fall, regardless of whether they have sold their investment. Investors are encouraged to contact Block & Leviton to learn more about their potential legal options. The deadline to seek appointment as lead plaintiff is September 14, 2026. Until a class is certified, investors are not represented by an attorney.

Whistleblowers who provide original information may receive rewards of up to 30% of any successful recovery.
