The complaint alleges that defendants disseminated materially false and misleading statements and omissions concerning the true state of Planet Fitness' customer acquisition and marketing metrics. According to the complaint, 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, according to the complaint, 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.
