Investors have until September 14, 2026, to ask the Court to be appointed to lead the case. The complaint asserts securities fraud claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of investors in Planet Fitness common stock. The class action is pending in the U.S. District Court for the District of New Hampshire. It is captioned Matsunaga v. Planet Fitness, Inc., et al., No. 26-cv-00576
Why is Planet Fitness Being Sued for Securities Fraud?
Planet Fitness is a large franchisor and operator of fitness centers across the United States. The company aims to offer a fitness experience in a non-intimidating environment, which it calls the Judgement Free Zone.
The complaint alleges that throughout the relevant period, Planet Fitness misrepresented the success of its marketing campaign to focus on “fitness-minded” members. For instance, Planet Fitness told investors that it “continue[d] to lean into our ‘we are all strong on this Planet’ campaign.” Planet Fitness also stated that “[b]ecause this campaign resonated so strongly last year, we extended it into 2026.”
In truth, Planet Fitness’s marketing campaign alienated fitness beginners and more casual gym-goers, which traditionally had been the company’s focus and would be forced to restructure its marketing strategy. This caused the company to halt planned increases which its sales projections were premised on
Why did Planet Fitness’s Stock Drop? On May 7, 2026, Planet Fitness released its Q1 2026 financial results. The company announced disappointing membership growth and cut 2026 revenue growth guidance from approximately 9% to about 7% and adjusted EBITDA growth guidance from roughly 10% to approximately 6%. During the same-day earnings call, the company stated that its marketing “may have pivoted too far” as the company “shift[ed] from [its] lighthearted approachable tone” to one that “increased penetration with the fitness-minded.” As such it announced that, “we are pausing the planned national Black Card price increase pending a broader pricing review.”
This news caused the price of Planet Fitness stock to decline $19.95 per share, or 31%, from a closing price of $63.96 per share on May 6, 2026, to $44.01 per share on May 7, 2026
