Planet Fitness (NYSE: PLNT) shares tumbled 5.12% in pre-market trading on Thursday following the release of its first-quarter 2025 financial results, which fell short of analyst expectations across key metrics.

The fitness center operator reported Q1 revenue of $276.7 million, missing the analyst consensus estimate of $279.2 million. While this represents an 11.55% increase from the same period last year, it wasn't enough to meet market expectations. Additionally, the company's adjusted net income came in at $50 million, below the estimated $51.7 million. Earnings per share (EPS) also disappointed, with Planet Fitness posting $0.59 per share compared to the expected $0.62.

Despite the earnings miss, Planet Fitness maintained a positive outlook, reiterating its guidance for the year ending December 31, 2025. The company projects a 10% growth in adjusted EBITDA for the full year. In response to concerns about potential tariff impacts, Planet Fitness stated that its exposure is limited at current tariff levels, but it is developing mitigation plans for potential future impacts. Investors will be watching closely to see how the company navigates these challenges and whether it can regain momentum in the coming quarters.
