Planet Fitness faces sharp stock decline after adjusting growth outlook amidst member growth challenges.

Planet Fitness reported a decline in its stock price to $47.63, down 35% from earlier in April and 57% year-to-date. Despite an overall positive first quarter with a 21.9% revenue increase, the brand lowered its year-end sales growth outlook from 4-5% to just 1%, reflecting challenges in net member growth during peak sign-up periods.
This suggests potential implications for franchisee unit economics as adjustments in growth outlook may affect new membership acquisition strategies and overall franchise performance.
Planet Fitness experienced a significant decline in its stock price following the release of its first-quarter financial results for 2026, despite reporting overall positive figures. On May 11, the stock closed at $47.63, reflecting a 35 percent decrease from $77.28 on April 9 and down 57 percent year to date from $109.73. The decline comes after a strong performance in 2025, where stock prices fluctuated between $90 and $112.
The company adjusted its year-end sales growth outlook downward, changing its forecast for systemwide same-store sales growth from 4 to 5 percent to just 1 percent. Anticipated revenue growth has also been revised from 9 percent to 7 percent, while the adjusted EBITDA forecast was lowered from 10 percent to 6 percent. These adjustments stem from lower-than-expected net new membership in the first quarter, impacting the company's results due to the seasonal nature of its membership model. CEO Colleen Keating commented, “In the first quarter, our top and bottom-line results exceeded expectations. However, 2026 is off to a slower-than-expected start from a net member growth perspective as we faced internal and external headwinds during our peak sign-up period. As a result, we are sharpening our marketing to prioritize capturing demand and driving net member growth.”
Despite these challenges, Planet Fitness reported a 21.9 percent increase in total revenue, moving from $276.7 million to $337.2 million compared to the first quarter of 2025. Systemwide same-club sales rose by 3.5 percent, and the overall systemwide sales increased by $88 million, reaching $1.4 billion. The brand also added 15 new gyms, bringing its total to 2,909 locations. This news contrasts with Noodle & Company, which saw a notable rise in its stock price, and H&R Block, which reported a strong closing price increase as well.
Looking ahead, franchise operators and investors may watch how quickly Planet Fitness can enhance its marketing strategies to stimulate net member growth amid ongoing market challenges.
