## **What Does Planet Fitness Do?**

It is a global fitness company with a majority U.S. presence. The company is one of the largest franchisors and operators of fitness centers in the world by member count and location footprint, and it reports results through Franchise, Corporate-Owned Clubs, and Equipment segments.

## **Why are Shareholders Suing Planet Fitness?**

The complaint alleges Planet Fitness overstated the strength of its 2025 marketing campaign, the viability of its planned Black Card price increase, and the achievability of its fiscal 2026 guidance and three-year growth algorithm. Plaintiffs allege the campaign was failing to resonate with fitness beginners and casual gym-goers, creating a material headwind to net member joins.

According to the complaint, defendants told investors that Planet Fitness was making significant progress on its long-term strategy, that its "We Are All Strong on This Planet" marketing campaign was resonating, and that its high-value, low-price subscription model remained resilient.

On November 6, 2025, Planet Fitness announced Q3 2025 results. Chief Executive Officer Colleen Keating stated that the company had continued the "We Are All Strong on This Planet" campaign, that its "strong join trend" had continued, and that Black Card penetration reached 66.1% of total membership. The same day, Keating said the company had decided to raise the Black Card price to $29.99 after the 2026 peak join season, after "significant testing and data analysis." Chief Financial Officer Jay Stasz added that prior testing showed the increase would be accretive to average unit volume.

The alleged truth emerged on May 7, 2026, when Planet Fitness announced Q1 2026 results and sharply reduced its outlook. The company said 2026 was off to a slower-than-expected start from a net member growth perspective due to internal and external headwinds during the peak sign-up period. Planet Fitness cut system-wide same club sales growth guidance to approximately 1%, down from 4% to 5%, reduced revenue growth guidance to approximately 7%, and lowered adjusted EBITDA growth guidance to approximately 6%.

Its share price declined dramatically. From a closing market price of $63.96 per share on May 6, 2026, Planet Fitness' stock price fell to $44.01 per share on May 7, 2026, a decline of about 31.19% in the span of just a single day.
