Latham Group (SWIM) Q1 2026: Gross Margin Expands 220bps as Fiberglass Mix Approaches 80%

May 5, 2026 | By EarningsIQ Research

Latham Group delivered margin expansion and steady sales growth in Q1 despite weather headwinds, with fiberglass pools now nearing 80% of segment mix for the year. Strategic focus on sand state penetration, targeted dealer activation, and operational efficiency are positioning the company to outperform a flat pool market. Management reaffirmed full-year guidance, citing early-season momentum and disciplined cost management as key supports for 2026.

Summary

• Margin Expansion Outpaces Market: Lean manufacturing and value engineering drove material gross margin gains amid flat demand.
• Fiberglass Strategy Scales Up: Targeted sand state initiatives and acquisitions are accelerating market penetration.
• Guidance Reaffirmed on Early-Season Strength: April order trends and operational discipline support full-year outlook.

Business Overview

Latham Group designs, manufactures, and distributes in-ground residential swimming pools and pool accessories, generating revenue through three main product lines: fiberglass pools, pool covers (including automatic safety covers), and pool liners. Fiberglass pools, pre-formed and rapidly installed pool shells, are the core growth driver, while covers and liners provide recurring replacement and value-add sales. The company’s business model leverages a mix of direct sales, dealer partnerships, and targeted acquisitions to expand geographic reach and product attachment rates.

Performance Analysis

First quarter results reflected steady execution in a challenging environment. Net sales rose 5% year-over-year, with organic growth of 3% and the remainder from the Freedom Pools acquisition. Gross margin expanded by 220 basis points to 32%, reflecting operating leverage and ongoing benefits from lean manufacturing and value engineering programs. Segment performance was balanced: in-ground pool sales grew 4%, covers advanced 6%, and liners increased 9%, demonstrating broad-based demand resilience.

Despite adverse weather compressing early-season activity, April order trends normalized, supporting management’s guidance for the year. SG&A rose 20%, primarily from strategic investments in sales, marketing, and digital transformation, as well as acquisition-related earn-out expenses. Adjusted EBITDA increased 9%, with margin up 40 basis points, as cost discipline offset higher operating expenses. Working capital needs spiked seasonally, and debt leverage remained stable at 2.8x.

• Fiberglass Mix Approaches 80%: Management expects fiberglass pools to comprise nearly 80% of in-ground pool sales for 2026, up from prior years, highlighting mix shift and category leadership.
• Acquisition Integration Drives Growth: Freedom Pools, acquired in February, contributed to sales and broadened Latham’s footprint in Australia and New Zealand.
• Margin Tailwind from Efficiency: Lean manufacturing and value engineering initiatives delivered $2 million in Q1 savings, with further gains expected as these programs mature.

Overall, Latham is capturing incremental growth and margin despite macro and weather headwinds, with disciplined execution and strategic investments supporting guidance.

Executive Commentary

Strategic Positioning

1. Sand State Penetration and Market Segmentation

Latham is intensifying focus on the “sand states” (southern U.S. growth markets), where penetration is low and category adoption for fiberglass pools is rising. The company’s new market development framework segments neighborhoods based on home value, lot size, and income, targeting micro-markets with the highest conversion potential. This granular approach is designed to optimize resource allocation and accelerate share gains.

2. Dealer Network Optimization and Activation

Dealer engagement is being retooled with an emphasis on account management and targeted expansion. Management is prioritizing extracting greater productivity from the existing core network in established regions, while selectively adding dealers in white space areas. In sand states, Latham is supporting dealers with targeted marketing, lead generation, and field sales resources to drive fiberglass adoption.

3. Brand Awareness and Direct-to-Consumer Insights

Marketing spend is shifting toward both national and hyper-local campaigns, leveraging partnerships (such as with Olympic gold medalist Cody Miller) to build awareness of pool safety and fiberglass benefits. The Freedom Pools acquisition also provides exposure to a direct-to-consumer model, offering learnings to inform U.S. strategy and increase customer attachment rates.

4. Operational Efficiency and Cost Management

Lean manufacturing and value engineering are embedded in Latham’s operating model, delivering consistent cost savings and supporting margin expansion. The company is actively managing transportation and commodity cost volatility with temporary surcharges and supplier diversification. Recent facility acquisitions in key states further support manufacturing flexibility and local responsiveness.

5. International Expansion and Synergy Capture

Global reach is expanding, with the Freedom Pools deal providing immediate scale and synergy potential in Australia and New Zealand. Management expects to leverage product, sales, and operational best practices across regions, with a focus on revenue synergies and operational integration.

Key Considerations

This quarter marks a strategic inflection for Latham, as management moves from defensive cost control to proactive market capture in targeted geographies and product categories.

Key Considerations:

• Sand State Execution: Early traction in Florida, with double-digit growth, will be a key test case for broader regional expansion and the effectiveness of new segmentation and sales strategies.
• Dealer Network Leverage: Ability to drive higher throughput from existing dealers and selectively add new partners will determine pace of share gains, especially in underpenetrated markets.
• Cost Pass-Through and Margin Protection: Temporary fuel surcharges are offsetting transportation inflation, but resin and other commodity costs remain a watchpoint for in-year margin stability.
• Acquisition Integration: Realization of expected synergies from Freedom Pools and CoverStar Central is critical for delivering on growth and margin commitments.
• Seasonality and Demand Visibility: Weather-driven timing shifts and competitive quoting environment could impact quarterly phasing, but April trends support full-year targets.

Risks

Key risks include input cost volatility (notably resins and freight), macroeconomic uncertainty impacting consumer discretionary spending, and competitive intensity in dealer channels. Financing constraints for end consumers, especially in higher-rate environments, may limit pool starts. Execution risk on sand state expansion and integration of recent acquisitions could impact revenue and synergy realization if not managed tightly.

Forward Outlook

For Q2, Latham expects:

• Order trends and shipping days to normalize, with Q2 and Q3 activity tracking historical seasonality.
• Continued margin support from cost initiatives and temporary surcharges.

For full-year 2026, management reaffirmed guidance:

• Revenue growth of 9% and adjusted EBITDA growth of 13% at the midpoint.

Management highlighted several factors that support this outlook:

• April sales trends in line with expectations, supporting confidence in guidance.
• Operational flexibility to adjust pricing and cost structure as commodity and freight dynamics evolve.

Takeaways

Investors should focus on Latham’s ability to translate early sand state traction and operational discipline into sustained market share gains and margin expansion.

• Sand State Playbook in Motion: Florida’s double-digit growth and new segmentation framework set the stage for broader regional wins, but execution and dealer activation will be key to scaling.
• Margin Resilience Underpins Valuation: Efficiency gains and disciplined cost pass-through provide a margin buffer in a flat demand environment, but input cost volatility remains a watchpoint.
• Acquisition and Integration Watch: Freedom Pools and CoverStar Central must deliver on synergy and growth promises to sustain the growth narrative and support guidance.

Conclusion

Latham’s Q1 demonstrated disciplined execution, margin expansion, and early validation of its sand state growth strategy. With strategic investments in sales, marketing, and operational efficiency, the company is positioning to outperform a flat market, but sustained success will require flawless execution on dealer activation, cost management, and integration of recent acquisitions.

Industry Read-Through

Latham’s results highlight a resilient demand environment for residential pools and accessories, with consumers prioritizing home investment over travel amid higher fuel costs. Fiberglass pool adoption is accelerating, a trend likely to pressure legacy concrete pool providers and benefit vertically integrated manufacturers with operational scale. Dealer channel competitiveness and consumer financing headwinds are key risks for the broader home improvement sector. Operational efficiency and targeted geographic expansion are emerging as critical differentiators for manufacturers across the building products and home leisure industries.
