Planet Fitness IncWeak member growth and lowered guidance due to weather, macro headwinds, competition, and marketing missteps.

Planet Fitness lowered its full-year guidance after weaker-than-expected member additions in the first quarter, according to Baron Small Cap Fund's second-quarter 2026 investor letter. The fund said member growth was pressured by unfavorable weather, macroeconomic headwinds, increased competition in certain markets, and marketing changes that did not resonate with certain customer segments. As a result, management reduced its outlook for the year to reflect the lower membership base and paused previously announced price increases. Planet Fitness shares closed at $50.63 on August 17, 2026, with a one-month return of -7.10% and a 52-week loss of -52.88%, giving the company a market capitalization of $3.82 billion. Baron Small Cap Fund noted that despite the disappointing results, Planet Fitness remains the category leader with scale advantages to capitalize on favorable long-term health and wellness trends.
