Wolf Haldenstein Adler Freeman & Herz LLP has filed a securities fraud class action lawsuit on behalf of investors who purchased Planet Fitness common stock between November 6, 2025, and May 6, 2026. The complaint alleges that the company made materially false and misleading statements and failed to disclose that it could not sustain membership growth without a significant marketing overhaul and could not proceed with the planned Black Card price increase. On May 7, 2026, Planet Fitness reported first quarter results, slashing same-store growth guidance from 4-5% to 1% and withdrawing its three-year growth algorithm, citing an ineffective marketing campaign and external competition. The stock fell $19.95, or 31.2%, to close at $44.01 per share that day. The lead-plaintiff deadline is September 14, 2026.
