What this transaction means for investors

Even after the reduction, Planet Fitness remains one of Dorsal Capital's largest holdings at 7.3% of assets, suggesting that conviction hasn't disappeared.

What's interesting is that the stock's weakness comes despite a business that is still growing. First-quarter revenue climbed 22% year over year to $337.2 million, while adjusted EBITDA increased nearly 20% to $139.9 million. System-wide same-club sales rose 3.5%, total membership reached roughly 21.5 million, and the company opened 15 new locations during the quarter.

Management did acknowledge some near-term challenges. CEO Colleen Keating said 2026 has gotten off to a "slower than expected start" for net member growth, prompting the company to sharpen its marketing efforts and pause a planned Black Card price increase. At the same time, she emphasized that Planet Fitness' long-term thesis remains intact and that the company is well-positioned to benefit from growing interest in health and wellness.

For long-term investors, the key question is whether today's slowdown proves temporary. If Planet Fitness can continue expanding its club base while converting more consumers into recurring memberships, the recent stock decline could eventually look disconnected from the underlying business.
