Planet Fitness reported first quarter 2026 revenue up 21.9% to $337.2 million and diluted earnings per share of $0.65, up from $0.50. The company cut several 2026 growth expectations after lower-than-planned net member joins in the first quarter and a decision to pause the national Black Card price increase, which affects shareholders' view of full-year results.
