On May 7, 2026, Planet Fitness reported its first quarter 2026 financial results and updated its full-year outlook. Among other items, Planet Fitness disclosed that “2026 is off to a slower than expected start from a net member growth perspective” as the Company faced “internal and external headwinds during our peak sign-up period.” The Company further disclosed that it was pausing its planned national Black Card price increase pending a broader pricing review. In addition, Planet Fitness stated that, based on “lower net joins than planned in the first quarter” and the decision to pause the Black Card price increase, it was reducing several of its 2026 growth expectations.
