Rosen Law Firm reminded investors who purchased Planet Fitness, Inc. common stock between November 6, 2025, and May 6, 2026, inclusive, that September 14, 2026, is the deadline to seek appointment as lead plaintiff in an already-filed securities class action. The lawsuit alleges that Planet Fitness and other defendants made materially false or misleading statements, or concealed adverse facts, about customer acquisition and marketing metrics. According to the allegations, updated marketing messaging failed to resonate with and intimidated fitness beginners and casual gym-goers, creating a significant headwind for net member joins during the peak first-quarter sign-up period. The complaint claims those conditions made Planet Fitness’ previously issued fiscal 2026 guidance and long-term financial targets unachievable, requiring a marketing-strategy overhaul and the cancellation of a planned Black Card price increase. No class has been certified. Investors may seek information through Rosen Law Firm, retain counsel of their choice, or remain absent class members without taking action; eligibility for any potential recovery does not depend on serving as lead plaintiff.
