Could Planet Fitness (PLNT) Rebound Despite Slower Member Growth?
Baron Capital's Q2 2026 investor letter notes Planet Fitness (PLNT) underperformed due to slower member growth, leading to lowered guidance. The company cited weather, macroeconomic factors, and competition as challenges. Despite this, Baron believes PLNT remains a category leader with long-term advantages. PLNT's stock is down 7.10% in one month and 52.88% over 52 weeks, with a market cap of $3.82 billion.
