Planet Fitness shares plunged 31% on May 7 after the company cut its 2026 revenue growth guidance to about 7% and disclosed a marketing strategy that alienated its core members.
Planet Fitness may have made false and misleading statements to investors regarding the purported success of its marketing campaign, Bleichmar Fonti & Auld LLP said in announcing its investigation. The securities law firm is probing whether the company's public statements about its shift toward "fitness-minded" members were accurate.
The company lowered its 2026 adjusted EBITDA growth forecast to roughly 6% from approximately 10%. On the same-day earnings call, management said its marketing "may have pivoted too far" as it moved from its "lighthearted approachable tone" to one that "increased penetration with the fitness-minded." The admission followed disappointing membership growth during the key first-quarter sign-up period.
The selloff erased $19.95 per share in value, with the stock closing at $44.01 on May 7 from $63.96 the prior day. The decline puts Planet Fitness shares at their lowest level since the company's marketing misstep came to light, testing investor confidence in the chain's "Judgement Free Zone" brand identity. The investigation could lead to shareholder class-action litigation, adding further pressure on the stock as the company works to regain its core membership base.
