Glancy Prongay Wolke & Rotter LLP reminded Planet Fitness, Inc. investors of the September 14, 2026 deadline to move for appointment as lead plaintiff in a putative class action covering securities purchased or otherwise acquired from November 6, 2025, through May 6, 2026, inclusive. The lawsuit follows Planet Fitness’s May 7 release of first-quarter 2026 results, which reduced same-store growth guidance from 4%-5% to 1% and withdrew its three-year growth algorithm introduced six months earlier. The company cited an over-pivoted marketing campaign that failed to resonate with its core customers and external competition, and said it was pausing the planned national rollout of a Black Card price increase to focus on rebuilding new membership growth. Planet Fitness shares fell $19.95, or 31.2%, to close at $44.01 on May 7. 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. The law firm said 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.
