Bleichmar Fonti & Auld LLP launched a securities fraud investigation into Planet Fitness after its stock plunged 31% on May 7 following a marketing misstep that alienated core members.

Bleichmar Fonti & Auld LLP launched a securities fraud investigation into Planet Fitness Inc. on June 1 after the fitness chain's stock plunged 31% on May 7, wiping out $2 billion in market value.
"The company's marketing may have pivoted too far as it shifted from its lighthearted approachable tone to one that increased penetration with the fitness-minded," Planet Fitness said during its May 7 earnings call, according to the law firm's investigation notice. The admission came as the company reported disappointing membership growth during the key first-quarter sign-up period.
Planet Fitness cut its 2026 revenue growth guidance to about 7% from roughly 9% and lowered adjusted EBITDA growth expectations to approximately 6% from about 10%. The stock fell $19.95 a share, closing at $44.01 on May 7, down from $63.96 the prior session. The company operates more than 2,600 fitness centers across the US under a franchise model built on its "Judgement Free Zone" brand promise.
The investigation centers on whether Planet Fitness made false or misleading statements about the success of its marketing campaign targeting "fitness-minded" members, a strategy that alienated its core casual-user base. The 31% single-day decline ranks among the steepest for US consumer discretionary stocks this year. Planet Fitness's next quarterly report will show whether the company can reverse membership trends or faces further erosion of its core market.
