US Fitness Chain Stocks Surge 5% After 25% Plunge

On the 17th, shares of Planet Fitness, Inc. (PLNT) closed at $52.98 on the New York Stock Exchange, up 5.52% from the previous day. The company’s market capitalization reached roughly $4.2 billion (about KRW 5.7 trillion), with a one-day increase of approximately $240 million (KRW 330 billion). Trading volume was around 1.43 million shares.

In its May first-quarter results, Planet Fitness reported revenue growth of about 21% and a membership base of 21.5 million. However, net member additions fell short of expectations, prompting the company to lower its 2026 outlook and postpone plans to raise PF Black Card prices. In early June, it further reduced its 2026 revenue guidance and canceled the planned price increase, sending the stock tumbling more than 25% in a single day. Reports that law firm Pomerantz had launched an investigation citing investor rights concerns added to the pressure, leaving the stock down over 30% in the past 90 days. Despite this downturn, several European financial outlets continue to issue “buy” or “outperform” ratings and set target prices well above the current level, fueling a view that this is a compelling low-price buying opportunity.

Planet Fitness operates approximately 2,900 low-cost fitness clubs across seven countries, including the U.S. and Canada, and is the world’s largest fitness chain with over 20 million members. Its franchise-focused “low price, high value” model, coupled with stable cash flows from recurring membership fees and franchise royalties, is viewed as a key strength. Colin Keating, appointed CEO in 2024, is pursuing a medium- to long-term growth strategy centered on club remodeling, enhanced digital services, and targeting younger demographics. ()
