The Law Offices of Frank R. Cruz announces an investigation of Planet Fitness, Inc. (“Planet Fitness” or the “Company”) (NYSE: PLNT) on behalf of investors concerning the Company’s possible violations of federal securities laws.

What Is The Investigation About?
On May 7, 2026, Planet Fitness released its first quarter 2026 financial results, slashing same-store growth from 4-5% to only 1%, and completely withdrawing its long-term three-year growth algorithm it had introduced just six months prior, citing, among other things, an over-pivoted marketing campaign that failed to resonate with its core customer base, alongside external competition. The Company further disclosed that it was pausing its planned national rollout of its Black Card price increase to prioritize revitalizing new membership growth.

On this news, Planet Fitness’s stock price fell $19.95, or 31.2%, to close at $44.01 per share on May 7, 2026, thereby injuring investors.
