Planet Fitness, Inc. (PLNT) operates a highly recognizable fitness club chain, primarily through a franchise model, offering a "Judgement Free Zone" experience at an affordable price. The company's business model is built on three main pillars: collecting fees from its franchisees, operating its own corporate-owned clubs, and selling fitness equipment to its franchisees.

1. The Business Model (How They Make Money)

Planet Fitness generates revenue through a diversified approach centered around its low-cost, high-value gym concept. Their core economic engine is driven by expanding their club footprint and growing their membership base.

• Franchise Segment: This is the largest revenue contributor. Planet Fitness earns money from its franchisees through royalty fees, which are a percentage of the franchisees' monthly membership dues, and through National Advertising Fund (NAF) contributions. They also collect initial franchise fees when new clubs are opened. For the second quarter of 2026, the franchise segment generated $135.8 million in revenue, representing approximately 37.2% of their total revenue.
• Corporate-Owned Clubs Segment: Planet Fitness directly owns and operates a portion of its clubs. Revenue from this segment comes directly from membership fees paid by members of these corporate-owned locations. This segment also serves as a testing ground for new initiatives before rolling them out to franchisees. In the second quarter of 2026, corporate-owned clubs contributed $143.9 million in revenue, accounting for roughly 39.4% of the total.
• Equipment Segment: The company sells fitness equipment, primarily cardio and strength machines, to its franchisees for their new and existing clubs. This ensures brand consistency and provides an additional revenue stream. For the second quarter of 2026, the equipment segment brought in $85.6 million in revenue, making up about 23.4% of their total business.

2. The Metrics That Matter Most

For Planet Fitness, understanding its financial health means looking beyond just the top-line sales. Here are the most important metrics to watch:

• Revenue: This metric simply measures the total amount of money Planet Fitness brings in from all its business activities – franchise fees, corporate club memberships, and equipment sales. For a growth-oriented company like Planet Fitness, consistently increasing revenue shows that more people are joining their gyms and that their franchise system is expanding. In the second quarter of 2026, Planet Fitness reported total revenue of $365.2 million. For the full year 2025, total revenue was $1.3 billion.
• Net Income: This is the company's profit after all expenses, including taxes, have been paid. It tells you how much money is left over for the owners (shareholders) after everything is accounted for. A growing net income indicates that the company is not only increasing sales but also managing its costs effectively. Planet Fitness's net income attributable to the company was $67.1 million in the second quarter of 2026. For the full year 2025, net income was $219.1 million.
• Operating Cash Flow: This metric shows the cash a company generates from its regular business operations before accounting for investments or financing activities. For Planet Fitness, strong operating cash flow is vital because it indicates they have enough cash from their gym memberships and franchise fees to cover day-to-day expenses, pay down debt, and fund future growth without relying heavily on borrowing. For the first half of 2026, Planet Fitness's operating cash flow was $193.4 million.
• CapEx (Capital Expenditures): This refers to the money a company spends to buy, maintain, or improve its physical assets, like buildings, equipment, or land. For Planet Fitness, CapEx is important because it reflects their investment in new corporate-owned clubs and the equipment they sell to franchisees. It shows how much they are putting back into the business to grow and keep their facilities up-to-date. In the first half of 2026, additions to property and equipment (CapEx) were $67.4 million.
• Operating Margin: This metric tells you how much profit a company makes from each dollar of sales after covering the direct costs of its operations, but before accounting for interest and taxes. For Planet Fitness, a healthy operating margin shows how efficiently they are running their gyms and managing their franchise system. A higher margin means they are doing a better job of turning sales into actual operating profit. Planet Fitness's operating margin was approximately 33.9% in the second quarter of 2026. At the end of 2025, the operating margin was 23.33%.

3. How to Value This Company

For Planet Fitness, the most relevant valuation metric is the P/E Ratio (Price-to-Earnings Ratio).

The P/E ratio compares a company's current stock price to its earnings per share (EPS). In simple terms, it tells you how much investors are willing to pay for each dollar of the company's annual profit.

Here's why it's the best fit for Planet Fitness:

• Profitability: Planet Fitness is a consistently profitable company, making the P/E ratio a straightforward way to assess its value based on its earnings power.
• Simplicity: It's a widely understood and easily calculated metric, making it accessible for everyday investors.
• Growth Expectations: A higher P/E ratio often suggests that investors expect the company's earnings to grow in the future. By comparing Planet Fitness's P/E to its historical P/E or to similar, profitable companies in the fitness or franchise industry, you can get a sense of whether the stock is considered cheap or expensive relative to its earnings potential.

For example, if Planet Fitness has a P/E ratio of 15, it means investors are paying $15 for every $1 of the company's annual earnings. You would then compare this to other companies or Planet Fitness's own past P/E to decide if that's a good deal. As of recent data, Planet Fitness had a trailing P/E ratio of 14.92 and a forward P/E ratio of 13.71.
