Planet Fitness faces securities probe after 31% stock crash

Bleichmar Fonti & Auld LLP is investigating Planet Fitness Inc. for potential securities fraud after the stock lost 31% in a single day.

"Planet Fitness may have made false and misleading statements regarding the purported success of its marketing campaign to focus on 'fitness-minded' members," the law firm said in a statement.

The probe follows Planet Fitness's May 7 disclosure of disappointing first-quarter membership growth. The company cut its 2026 revenue growth guidance to about 7% from approximately 9% and lowered adjusted EBITDA growth guidance to roughly 6% from about 10%. On the same-day earnings call, management said its marketing "may have pivoted too far" as it shifted from a "lighthearted approachable tone" to one that "increased penetration with the fitness-minded."

The stock closed at $44.01 on May 7, down from $63.96 the prior session, and has since recovered to about $51 — still 53.5% lower year to date. The company also paused a planned national Black Card price increase and cut several 2026 growth targets, raising questions about pricing power and membership resilience.

Pomerantz LLP has opened a separate investigation into Planet Fitness for potential securities fraud or unlawful business practices, the firm said. The dual probes put added scrutiny on Planet Fitness's franchise-heavy business model, which relies on steady club additions and low member churn to drive growth. The company has authorized up to $500 million in share repurchases and has retired millions of shares in recent years, though buybacks do little to offset structurally weaker unit growth or sustained pressure on churn.

The investigations shift the risk calculus for Planet Fitness holders, who now face potential legal liabilities alongside the operational headwinds. Investors will watch for any updates from the company's internal business review and for the outcome of the securities probes, which could influence the stock's valuation relative to its $66.64 analyst price target.
