Planet Fitness delivered a solid second quarter, but analysts at RBC Capital Markets are flagging a potential speed bump: a new $10-a-month membership trial that could cool the gym chain's growth by steering customers toward cheaper plans.
RBC, an investment bank, said the company largely stuck to its 2026 outlook, but its full-year guidance now implies roughly flat same-store sales in the second half. Same-store sales measure how existing gyms perform, and RBC believes recent gains have been driven almost entirely by higher monthly fees rather than more members. That approach works until pricing gets challenged, because there's less volume growth to absorb a discount.
What's behind the $10 test?
Planet Fitness is known for its low-cost, high-value model—typically around $10 to $15 a month—but it has been gradually raising prices in recent years to offset rising costs. The new $10 promotion appears to be a test to attract budget-conscious members, possibly in specific markets or for a limited time. While it could boost membership numbers, it also risks pulling existing members into cheaper tiers, which would lower average revenue per user.
RBC's note suggests that the promotion could pressure the company's pricing power, a key driver of its recent growth. If more members pay $10 instead of higher rates, same-store sales—which already look flat—could weaken further. The company's guidance already points to a slowdown, and the test adds another layer of uncertainty.
Why same-store sales matter
Same-store sales are a critical metric for retailers and gym chains because they show whether existing locations are growing, independent of new store openings. A flat reading means the company is essentially treading water—not losing ground, but not gaining much either. For investors, that's a sign that growth may be slowing, especially if the company has been relying on price hikes rather than new members.
Planet Fitness's situation is not unique. Many consumer-facing companies have used pricing power to offset inflation, but that strategy has limits. When customers push back or competitors offer cheaper alternatives, companies often have to respond with promotions—which can erode margins. The $10 test is a classic example of that tension.
What it means for investors
For everyday investors, the key takeaway is that Planet Fitness's growth engine may be shifting. The company beat expectations in Q2, which is positive, but the guidance for flat same-store sales in the second half suggests the momentum is fading. The $10 promotion could be a smart move to defend market share, but it also signals that the company is willing to trade pricing power for volume.
Investors should watch how the test performs. If it brings in a wave of new members without cannibalizing existing revenue, it could be a win. If it simply lowers the average ticket, it could pressure profits. RBC's caution reflects that uncertainty.
Planet Fitness is not alone in facing these dynamics. Other companies have navigated similar pricing challenges, as seen in Porsche's strong first-half margins and Bridgestone's pricing power, which helped them weather weaker demand. But those are premium brands with loyal customers; Planet Fitness's value proposition is its low price, which makes it more sensitive to discounting.
Also worth noting: Planet Fitness recently cut its profit outlook as interest costs climbed, a reminder that higher borrowing costs are squeezing many companies. That adds another layer of pressure as the chain experiments with pricing.
The bigger picture
The fitness industry is competitive, with rivals like Peloton and boutique studios vying for the same dollars. Planet Fitness's scale and low-cost model give it an edge, but the $10 test shows even the low-cost leader feels the need to compete on price. For investors, the question is whether this is a temporary tactic or a sign of a longer-term shift in strategy.
RBC's note doesn't change the fact that Planet Fitness beat Q2 expectations, but it does temper enthusiasm. The second half could be choppy, and the $10 promotion is a wildcard. As always, investors should focus on the fundamentals—membership growth, revenue per member, and same-store sales—rather than short-term noise.
In the meantime, the broader market is watching how companies balance growth and profitability. As seen with Ralph Lauren's beat on Asia boom but disappointing forecast, even strong quarters can be overshadowed by cautious guidance. Planet Fitness is in a similar boat: the Q2 beat is real, but the road ahead looks bumpier.
