A cheap gym story needs member growth back

01 Running thesis

The fix is about joins

Planet Fitness still has a strong idea: cheap gyms that feel safe for people who do not see themselves as gym people. That idea built a very large franchise system. As of March 31, 2026, the company had 21.5 million members and 2,909 clubs.

The problem is that the growth story cracked in Q1. Management said its marketing leaned toward a more fitness-minded customer and did not connect well enough with the beginner or casual gym goer. Net member growth was 700k, below about 1M a year earlier. The company then cut full-year 2026 same-store sales guidance to about 1% and withdrew its 3-year outlook.

The bull case is simple. If the brand shifts back to its core message and joins improve in Q2 and Q3, the lowered expectations may leave room for the stock to work. The franchise model can still produce revenue and adjusted EBITDA growth even in a softer year.

The bear case is also clear. The weak joins may not be only a bad ad campaign. Other High-Value, Low-Price gyms may be taking share, and the paused Black Card price increase removes a near-term sales and margin boost. Until member growth turns, this is a reset story, not a clean growth story.

May 2026Planet Fitness cut its 2026 outlook to about 1% same-store sales growth and withdrew its 3-year outlook. The change followed weak Q1 member growth and a pause in the national Black Card price increase.
May 2026Q1 revenue rose 21.9% to $337.2 million, helped by a 123.4% jump in Equipment revenue. The strength helped earnings, but it did not solve the softer member growth issue.
Feb 2026The 2025 Form 10-K confirmed strong 2025 same-club sales and equipment sales. It did not change the core business model or risk picture.
Feb 2026Management first framed 2026 as the lowest growth year in its 3-year plan, with expected system-wide same-club sales growth of 4% to 5%. At that time, the Black Card price increase was still expected after peak join season.
Nov 2025The Q3 2025 Form 10-Q confirmed the earnings release and stated that risk factors had not materially changed. The thesis stayed focused on pricing power, churn, and unit growth.
Nov 2025Management announced a plan to raise the Black Card price to $29.99 in 2026 and raised 2025 guidance. Attrition was higher year over year, but management said it was not out of line on a multi-year view.
Aug 2025The Q2 2025 Form 10-Q confirmed growth across Franchise, Corporate-owned clubs, and Equipment. No new material risk factors were disclosed.
Aug 2025Online cancellation created higher attrition and delayed the Black Card pricing decision. Strong same-club sales still showed pricing power, but member growth risk rose.
02 Business model

Franchises fund the flywheel

Planet Fitness makes money in three main ways. It collects royalties, ad fund contributions, and fees from franchisees. It also owns some clubs and collects member dues there. Finally, it sells new and replacement fitness equipment to franchisee-owned clubs.

The best part of the model is the franchise segment. Franchisees put up most of the money to open clubs, while Planet Fitness collects fees tied to the system. That makes the business less asset-heavy than a gym chain that owns most of its sites.

The consumer offer is High-Value, Low-Price, meaning a basic gym at a low monthly fee. The Classic Card starts at $15 per month for new members. The Black Card costs about $24.99 per month and adds access to all locations, guest privileges, and perks like massage chairs.

Where the model breaks is scale. Franchisees need good club returns to keep opening sites, and the brand needs a steady stream of new members to support same-club sales. Higher construction costs, more online cancellations, and weaker marketing all pressure that loop.

What customers and franchisees buy

Steady

Classic Card

The basic membership gives access to one home club for $15 per month for new members. It is the main entry point for the casual gym user Planet Fitness wants back.

Growth engine

Black Card

This premium tier is about $24.99 per month and adds all-location access, guest privileges, and extra amenities. Penetration reached 67% as of March 31, 2026, but the planned national price increase is paused.

Cash cow

Franchise royalties and fees

Franchisees pay Planet Fitness royalties, ad fund contributions, and other fees. This is the highest-margin part of the business and depends on healthy club sales.

Steady

Corporate-owned clubs

Planet Fitness owns 292 clubs out of 2,909 as of March 31, 2026. These stores give the company direct membership revenue and a way to test changes.

Option

Equipment sales

The company sells fitness equipment to franchisees for new clubs and re-equips. Q1 2026 Equipment revenue rose 123.4%, mainly from sales to existing franchisee-owned clubs.

05 Risk factors

What could go wrong

Marketing reset fails

High impact · Medium odds

Management said the recent campaign spoke more to fitness-minded consumers than to beginners and casual gym goers. If the new message does not improve joins, the same-store sales guide may still be too high.

We watchNet member growth and management comments on Q2 and Q3 join trends.

Churn stays high

High impact · Medium odds

Online cancellation makes it easier for members to leave. Management also expects attrition to stay in the top half of its historical 3% to 4% monthly range, partly due to a younger Gen Z mix. Higher churn means the company must replace more members before it can grow.

We watchMonthly attrition commentary and the mix between gross joins and cancellations.

Franchisee returns weaken

High impact · Medium odds

Construction costs are up more than 30% versus 2019, which lowers returns for new clubs. Planet Fitness still expects 180 to 190 new stores in 2026, but openings are heavily weighted to the back half of the year. If returns do not improve, franchisees may slow development.

We watch2026 openings versus the 180 to 190 target and any update on club-level returns.

Competition spreads

Medium impact · Medium odds

The bear case is that weak joins are not only a marketing issue. Other low-price gyms may be pressuring Planet Fitness, especially in regions where management has already seen pressure. That would make a quick rebound harder.

We watchSame-club sales by region, especially South Central and Southeast markets.

Black Card pricing stays on hold

Medium impact · High odds

The planned national Black Card price increase was supposed to help revenue and margins. Management paused it because price increases can hurt joins in the short term. If joins stay weak, that price lever may remain unavailable.

We watchAny update on smaller price tests or a new national Black Card timing plan.

Weight-loss drugs change demand

Medium impact · Medium odds

New weight-loss medications could change how some consumers think about fitness. If fewer people see gyms as needed for health goals, member demand could weaken. This is an outside risk, but it matters for a low-price membership model built on mass appeal.

We watchManagement commentary on demand from new members using weight-loss medications.
06 Quick answers

In one breath

How does Planet Fitness make money?

It earns royalties and fees from franchisees, dues from company-owned clubs, and revenue from selling equipment to franchisee-owned clubs. The franchise segment is the key profit engine because franchisees fund most store growth.

Why did Planet Fitness cut guidance in 2026?

Management said Q1 member growth came in below expectations. It blamed part of the miss on marketing that appealed more to fitness-minded consumers and less to the beginner or casual gym goer.

What is the Black Card price issue?

Planet Fitness had planned a national Black Card price increase, but paused it to protect member joins. That helps the long-term scale goal, but it delays a near-term revenue and margin boost.

What should investors watch next?

The main signal is whether net member growth improves in Q2 and Q3 after the marketing pivot. Investors should also watch attrition, new store openings, and any update on Black Card price tests.
