Summary of the Action

Defendants provided overwhelmingly positive statements to investors while, at the same time, disseminating materially false and misleading statements and/or concealing material adverse facts concerning the true state of Planet Fitness' customer acquisition and marketing metrics. Notably, the Company's updated marketing messaging was failing to resonate with, and was actively intimidating, its core target demographic of fitness beginners and casual gym-goers. As a result, Planet Fitness was experiencing a significant headwind in net member joins during its peak first-quarter sign-up period that rendered its previously issued fiscal 2026 guidance and long term financial targets unachievable. On May 7, 2026, Planet Fitness announced its financial results for the first quarter of fiscal year 2026, revealing that its critical peak sign-up period was off to a slower-than-expected start internally. Management slashed full-year 2026 growth guidance, notably slashing same-store growth from 4-5% to only 1%, and completely withdrew its long-term three-year growth algorithm it had introduced just six months prior. Planet Fitness attributed these results to an over-pivoted marketing campaign that failed to resonate with its core customer base, alongside external competition, macroeconomic, and weather related impacts. Management then announced they were pausing the planned national rollout of the Black Card price increase to prioritize revitalizing new membership growth. Following this news, the price of Planet Fitness' common stock 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.
