Planet Fitness (PLNT) Q4 2025: Black Card Penetration Climbs to 66.5%, Unlocking Rate-Driven Margin Leverage

Planet Fitness exited 2025 with record black card penetration and a marked acceleration in club openings, positioning its asset-light franchise model for sustained cash flow and rate-driven growth in 2026. Strategic investments in AI-enabled marketing and member experience are set to further differentiate the brand, while the company navigates near-term headwinds from attrition normalization and equipment replacement cycles. Investors should focus on the evolving membership mix and the impact of national advertising fund (NAF) centralization as levers for future margin expansion.

Summary

  • Membership Mix Shift: Black card penetration reached an all-time high, supporting pricing power and retention.
  • Growth Engine: Accelerated club openings and international expansion underpin long-term unit growth.
  • AI-Driven Marketing: Increased national ad fund spend fuels targeted digital initiatives and efficiency gains.

Performance Analysis

Planet Fitness delivered robust top-line growth in Q4 2025, with all three revenue segments—franchise, corporate-owned clubs, and equipment—posting healthy gains. System-wide same club sales grew, driven predominantly by rate increases as black card, premium membership tier, penetration reached 66.5%. Notably, 80% of the comp increase was attributed to higher average rates, with the remainder from net new member additions.

Club expansion accelerated, with a record 104 new locations in Q4 and 181 total openings for the year, reflecting a more than 20% increase in unit growth versus 2024. The equipment segment benefited from this pace, with 60% of Q4 equipment revenue stemming from replacement cycles, an important dynamic given the asset-light, franchise-first model that emphasizes recurring royalty streams and low capital intensity for the corporate parent.

  • Rate-Driven Comp Growth: The majority of same club sales growth came from pricing, not volume, highlighting the importance of premium tier adoption.
  • Equipment Revenue Cyclicality: Elevated replacement activity and club openings back-loaded to Q4, impacting quarterly revenue cadence.
  • Margin Resilience: Adjusted EBITDA margin expanded both sequentially and year-over-year, despite higher SG&A and national advertising fund expense.

Cash flow remained strong, enabling $350 million in accelerated share repurchases and a $750 million debt refinancing at a 5.4% blended coupon. The company’s balance sheet flexibility supports ongoing buybacks and strategic investments, even as interest expense rises in 2026 due to refinancing and incremental leverage.

Executive Commentary

"Our strong 2025 performance is a direct result of our discipline and focus on our four strategic imperatives. We ended the year with approximately 20.8 million members and a global footprint of nearly 2,900 clubs, reinforcing the quality of our member experience and our compelling value proposition."

Colleen Keating, Chief Executive Officer

"Our highly franchised asset-light model continues to generate significant predictable cash flow. This has allowed us to return nearly $800 million to shareholders through buybacks over the last two years while also funding strategic investments for future growth."

Jay Stas, Chief Financial Officer

Strategic Positioning

1. Premiumization and Member Experience

Black card penetration, now at 66.5%, is a structural lever for rate growth and margin expansion. The company is piloting new Black Card spa amenities, such as cold plunge and red light sauna, aiming to drive both upgrades and retention. Early member feedback is positive, suggesting potential for further premiumization and higher lifetime value.

2. AI-Enabled Marketing and Retention

Centralized national ad fund (NAF) spending and investment in AI-enabled CRM, dynamic content optimization, and predictive churn modeling are designed to personalize outreach, increase member retention, and drive marketing efficiency. The 2026 shift of local ad spend to the NAF accelerates these initiatives, with early signs of improved digital join conversion and rejoin rates.

3. Aggressive Club Expansion and International Growth

Planet Fitness is leveraging franchisee-led acquisitions and conversions, especially in tight real estate markets, to accelerate domestic growth. Internationally, the company surpassed 1 million members and 200 clubs outside the US, with a focus on scaling in Mexico, Australia, and Spain, and entering one to two new markets annually. The Spain market is being transitioned to a franchise model to further accelerate growth.

4. Strategic Response to GLP-1 Trends

GLP-1s, a class of weight-loss drugs, are reshaping consumer wellness. Planet Fitness is positioning itself as the gym of choice for this demographic, partnering with Roe to offer discounts and benefits to GLP-1 users and highlighting the need for strength training to offset muscle loss. Early results from this partnership are promising, with high conversion rates.

5. Digital Engagement and Rejoin Dynamics

The company’s mobile app remains the top download in health and fitness, a key touchpoint for early member engagement. Rejoin rates are now in the mid-30% range, reflecting effective outreach to lapsed members and the impact of digital self-service features such as Click to Cancel, which also de-risks the business against regulatory change.

Key Considerations

Planet Fitness’s 2025 results and 2026 guidance reflect a model in transition, balancing mature market rate gains with unit expansion and digital transformation. Investors should watch for the following:

Key Considerations:

  • Membership Quality Over Quantity: Rate growth, driven by black card upgrades, is now a larger driver of comps than net new joins, signaling a shift toward premiumization.
  • Back-Loaded Growth Cadence: Club openings and equipment placements are heavily weighted to the second half, with Q4 expected to deliver the majority of new units and related revenue.
  • Advertising Efficiency and AI ROI: The shift to centralized NAF spending and AI-powered marketing is expected to improve member acquisition and retention, but execution risk remains as new tools are scaled.
  • Attrition Normalization: Attrition rates are tracking within historical norms post-Click to Cancel, but remain a key watchpoint as digital self-service features mature and regulatory scrutiny persists.
  • Rising Interest Expense: Debt refinancing and incremental leverage will drive interest expense up by $29 million year-over-year, partially offsetting operating leverage gains.

Risks

Near-term risks center on attrition volatility, especially as digital membership management matures and cancellation becomes easier. The heavy back-end loading of club openings and equipment revenue introduces quarterly earnings variability. Rising interest expense from recent refinancing and ongoing macroeconomic uncertainty may pressure net income and cash flow. Regulatory risk around subscription management remains, though Planet Fitness’s proactive digital approach partially mitigates this exposure.

Forward Outlook

For Q1 2026, Planet Fitness guided to:

  • System-wide same club sales growth of 4% to 5%
  • 180 to 190 new club openings for the full year, with the majority in the second half

For full-year 2026, management expects:

  • Total revenue growth of approximately 9%
  • Adjusted EBITDA growth of approximately 10%
  • Adjusted net income growth of 4% to 5%
  • Adjusted diluted EPS growth of 9% to 10%

Management highlighted the impact of equipment replacement cycles, back-loaded club openings, and planned black card price increases (post-peak join season) as key factors shaping the year. Share repurchases of $150 million are planned, and capital expenditures are expected to rise 10% to 15% as investment in new clubs and remodels continues.

Takeaways

Planet Fitness is evolving from a pure growth story to a model focused on premiumization, digital engagement, and strategic capital allocation.

  • Premiumization Drives Margin: Black card penetration and targeted price increases are structural levers for sustained rate-driven margin expansion, even as member growth moderates.
  • AI and Centralized Marketing Are Core Differentiators: The shift to national ad fund and digital-first member engagement will be pivotal in driving future retention and acquisition efficiency.
  • Execution on Expansion and Member Mix Is Key: Investors should monitor the cadence of new club openings, the success of international franchising, and the impact of new wellness amenities and GLP-1 partnerships on both join volume and lifetime value.

Conclusion

Planet Fitness enters 2026 with strong momentum in premium membership adoption, a robust pipeline of new club openings, and a sharpened focus on AI-enabled marketing and digital retention. While near-term earnings growth is tempered by equipment cycles and higher interest expense, the franchise’s asset-light model and evolving member mix position it for long-term margin and cash flow expansion.

Industry Read-Through

The Planet Fitness results highlight a broader shift in the fitness industry toward premiumization, digital engagement, and wellness integration. The rising importance of high-value, low-price (HVLP) models, combined with the adoption of AI-driven marketing and subscription management, signals that scale and technology will be key differentiators going forward. Competitors with less flexible models or slower digital adoption may struggle to match the rate-driven growth and retention gains seen at Planet Fitness. The company’s proactive approach to regulatory trends and GLP-1 partnerships also foreshadows a convergence of fitness, healthcare, and personalized wellness across the sector.
