Planet Fitness director Stephen Spinelli Jr. purchased 10,000 Class A shares on August 9, 2026, at $49.28 per share, a transaction valued at $492,800 that brought his direct holdings to 45,516 shares, according to SEC Form 4 data.
The purchase occurred while the stock traded near $49.10, down 55.25% year to date and 53.17% over the trailing twelve months, even after a modest one-day gain of 1.74%. A widely followed valuation model pegs fair value at $66.64, implying a 26.3% discount to the recent close.
The backdrop is a sharp reset triggered by the company's first-quarter results. On May 7, 2026, shares fell 31.19% in a single session, dropping from $63.96 to $44.01, after management disclosed that a national marketing campaign aimed at "fitness-minded" members failed to resonate with the core audience of beginners and casual gym-goers. The disappointment materialized during the critical Q1 sign-up period, producing a material headwind in net member joins.
A securities class action has since been filed in the U.S. District Court for the District of New Hampshire, captioned Matsunaga v. Planet Fitness, Inc., et al., No. 26-cv-00576. The complaint alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 on behalf of investors who purchased shares between November 6, 2025 and May 6, 2026. The lead-plaintiff deadline is September 14, 2026.
