A Planet Fitness securities class action alleges the Company repeatedly reassured investors about membership growth, marketing effectiveness, and Black Card pricing before PLNT shares fell 31.19% in one day.

NEW YORK, July 29, 2026 /PRNewswire/ — Levi & Korsinsky, LLP alerts investors in Planet Fitness, Inc. (NYSE: PLNT) that a class action has been filed on behalf of shareholders who purchased securities between November 6, 2025 and May 6, 2026. See if you could be eligible to recover . Joseph E. Levi, Esq. at jlevi@levikorsinsky.com  or (212) 363-7500.

The complaint alleges that Planet Fitness had previously created an overly positive impression about its marketing effectiveness, membership growth outlook, Black Card pricing initiative, and ability to meet fiscal 2026 and long-term targets. After the Company announced first-quarter results, the market allegedly reassessed those assumptions in a single trading session. PLNT closed at $63.96 on May 6, 2026 and fell to $44.01 on May 7, 2026, a decline of $19.95 per share, or approximately 31.19%. The lead plaintiff deadline is September 14, 2026.

The Marketing Campaign

According to the lawsuit, Planet Fitness made materially false and misleading statements about the effectiveness of its national marketing campaign and its ability to achieve projected membership growth. The complaint alleges that the Company’s campaign failed to resonate with its core audience of fitness beginners and casual gym-goers, creating a material headwind in net member joins during the Company’s critical first-quarter sign-up period.

The Plan to Increase the Black Card Price

The lawsuit asserts that Planet Fitness presented confidence in a planned national Black Card price increase to $29.99 while allegedly failing to disclose that its marketing conditions were undermining net member joins during the critical first-quarter sign-up period. As alleged, the Company’s long-term growth algorithm depended heavily on rate increases and membership volume that could not be achieved without a marketing reset.

The May 7 Guidance Revision

Both of these factors allegedly attributed to a decline same-club sales growth, revenue growth, adjusted EBITDA, and adjusted net income per share expectations. Ultimately, on May 7, 2026, Planet Fitness reduced same-club sales growth guidance from 4% to 5% to approximately 1%, lowered revenue growth expectations from approximately 9% to approximately 7%, and reduced adjusted EBITDA growth expectations from approximately 10% to approximately 6%.
