Glancy Prongay Wolke & Rotter LLP reminded investors of the September 14, 2026 deadline to seek appointment as lead plaintiff in a putative securities class action against Planet Fitness, Inc. The case covers investors who purchased or otherwise acquired Planet Fitness securities between November 6, 2025, and May 6, 2026, inclusive. The complaint alleges that defendants made materially false or misleading statements and failed to disclose adverse information about the company's business, operations and prospects. On May 7, 2026, Planet Fitness reported first-quarter results, reduced same-store growth guidance from 4%-5% to 1%, withdrew its three-year growth algorithm introduced six months earlier, and said it was pausing the planned national rollout of its Black Card price increase. The company cited an over-pivoted marketing campaign that did not resonate with its core customers and external competition. Planet Fitness shares fell $19.95, or 31.2%, to close at $44.01 on May 7. The complaint alleges that the company could not sustain membership growth at the required rate without a substantial marketing overhaul or new campaigns, and that its guidance relied significantly on the planned Black Card price increase. Investors do not need to take action to remain absent members of the class and may retain counsel of their choice or take no action.
