Latham Group (SWIM) Q4 2025: Fiberglass Pool Sales Hit 76.5% of Mix, Driving Margin Expansion
Latham outperformed a declining pool market in Q4 2025, propelled by continued fiberglass adoption and margin expansion. Strategic investment in sand states and product innovation is setting the stage for further share gains, even in a flat demand environment. With new leadership leaning into branding and operational discipline, Latham is positioning for above-market growth and improved profitability in 2026.
Summary
- Fiberglass Penetration Accelerates: Latham’s mix shift further entrenches its leadership in a structurally advantaged category.
- Sand States Expansion Focus: Florida outperformance and targeted dealer development underpin regional growth strategy.
- Margin Structure Strengthens: Operational leverage and lean initiatives are yielding sustainable profitability gains.
Performance Analysis
Latham delivered robust Q4 and full-year results, outperforming industry declines by leveraging its category leadership in fiberglass pools and auto covers. Net sales advanced as all three product lines—inground pools, covers, and liners—posted year-over-year growth, with fiberglass pool sales rising 2.5% and comprising 76.5% of in-ground pool mix. Notably, this performance came against a backdrop of low to mid-single digit declines in U.S. in-ground pool starts, highlighting Latham’s ability to capture share in a contracting market.
Margin expansion was a standout, with gross margin up 340 basis points in Q4 and adjusted EBITDA margin advancing 630 basis points year-over-year. These gains were driven by higher plant utilization, lean manufacturing, and value engineering programs. SG&A increases reflected deliberate investment in sales, marketing, and digital tools to accelerate fiberglass and auto cover adoption, especially in targeted regions like Florida. Cash flow remained healthy, with operating cash generation supporting both organic initiatives and acquisitions, including the strategic purchase of Freedom Pools in Australia and New Zealand.
- Fiberglass Share Gains: Fiberglass pools now represent over three-quarters of Latham’s in-ground pool sales, a meaningful shift that enhances profitability and competitive differentiation.
- Auto Cover Momentum: Auto cover sales surged 22% in 2025, reflecting strong consumer demand for safety and operational savings.
- Operational Leverage: Volume growth and process efficiency drove the majority of margin gains, validating the company’s manufacturing strategy.
Latham’s ability to grow in a down market, coupled with disciplined cost management and targeted capital allocation, signals resilience and sets a foundation for continued outperformance as demand stabilizes.

Strategic Positioning
1. Fiberglass Category Leadership
Latham’s sustained focus on fiberglass pools—pre-formed, factory-built pools offering faster installation and lower maintenance—has driven a mix shift that boosts both market share and margins. With U.S. fiberglass penetration still far below international benchmarks, leadership sees a “substantial runway” for growth, particularly in the large sand states region.
2. Sand States Expansion
Florida and Arizona are now the epicenter of Latham’s expansion strategy, with Florida delivering double-digit growth and outpacing local permit trends. Dealer network development and partnerships with homebuilders in master-planned communities are central to unlocking further adoption, while Texas remains a challenge due to permit declines.
3. Operational Excellence and Margin Discipline
Lean manufacturing and value engineering—continuous process and product improvement methodologies—are delivering sustainable cost advantages and plant utilization benefits. These programs have matured, but management expects further incremental gains, particularly from newer product reengineering initiatives.
4. Product Innovation and Digital Tools
Proprietary tools like Measure and MeasureGo—AI-powered measurement applications for liners and covers—are accelerating installer adoption and improving lead times, supporting share gains in both liners and safety covers. The company is also tailoring products for regional preferences, ensuring relevance in growth markets.
5. Strategic M&A and Geographic Diversification
The recent acquisition of Freedom Pools extends Latham’s reach into Australia and New Zealand, where fiberglass pools are already mainstream. This move diversifies end-market exposure and provides immediate earnings accretion, while the purchase of key U.S. manufacturing sites secures critical capacity for future growth.
Key Considerations
Latham’s Q4 and full-year results highlight a company executing on multiple levers—category leadership, operational discipline, and targeted investment—against a tough macro backdrop. Investors should weigh the following:
Key Considerations:
- Mix Shift to Higher-Margin Products: Continued conversion to fiberglass and auto covers is structurally lifting margins and competitive differentiation.
- Sand States as Growth Engine: Regional focus, especially in Florida, is yielding above-market growth, but broader sand state penetration depends on replicating success in Texas and Arizona.
- Operational Efficiency as Margin Driver: Lean and value engineering programs are mature, but incremental gains are still expected, particularly from product-side innovation.
- Capital Allocation Discipline: Acquisitions (Freedom Pools, U.S. facility purchases) are strategic, earnings-accretive, and support geographic and product diversification.
- Dealer and Builder Channel Development: Deeper engagement and segmentation of dealer networks, along with builder partnerships, are key to accelerating adoption in new and existing markets.
Risks
Market demand remains constrained by macro headwinds such as interest rates and consumer confidence, with management guiding for flat U.S. pool starts in 2026. Execution risk exists in scaling sand state penetration, especially given Texas market softness. Elevated SG&A from growth investments could pressure margins if top-line momentum stalls. Pricing power remains limited, with only modest benefit from recent tariff-related adjustments. Acquisition integration and capacity utilization also warrant monitoring as the company expands globally.
Forward Outlook
For Q1 2026, Latham guided to:
- Flat U.S. in-ground pool starts, with continued outperformance from fiberglass and auto covers.
- Mid-single-digit organic growth, augmented by Freedom Pools acquisition contribution.
For full-year 2026, management raised guidance:
- Net sales of $580 to $610 million
- Adjusted EBITDA of $105 to $120 million
Management highlighted several factors that will shape performance:
- Incremental margin gains from operational initiatives, though at a more moderate pace than prior years
- Increased marketing spend to drive brand awareness and dealer development, especially in sand states
Takeaways
Latham’s execution in 2025 demonstrates resilience and strategic clarity, with category expansion and operational discipline driving outperformance in a flat market.
- Category Leadership Drives Share Gain: Fiberglass and auto covers are the core growth engines, with further upside as U.S. adoption lags international benchmarks.
- Regional Strategy Shows Promise: Florida’s double-digit growth validates the sand states playbook, but broader success hinges on replicating this in Texas and Arizona.
- Margin Structure Remains Robust: Operational efficiency, lean initiatives, and measured SG&A investment provide a foundation for further profitability, even as the company invests for growth.
Conclusion
Latham enters 2026 with momentum, a structurally advantaged product mix, and a clear playbook for regional and international growth. The company’s focus on operational excellence and disciplined capital allocation positions it to outperform as market conditions stabilize and demand recovers.
Industry Read-Through
Latham’s results underscore the power of category leadership and operational discipline in a cyclical, project-driven industry. The continued shift toward fiberglass pools highlights a broader trend toward lower-maintenance, faster-installation solutions in residential construction.
