Latham Group, Inc. (SWIM)

Executive Summary / Key Takeaways

• Structural Transformation in a Trough Market: Latham has re-engineered its cost base through lean manufacturing and value engineering initiatives, delivering 390 basis points of EBITDA margin expansion in Q3 2025 despite a flat pool market, positioning the company to generate disproportionate earnings leverage when volumes recover.

• Fiberglass Market Share Acceleration: Latham is driving fiberglass penetration from 18% of U.S. in-ground pool starts in 2021 to approximately 24% in 2025, capturing the fastest-growing segment while commanding premium pricing and faster installation economics that concrete and vinyl cannot match.

• Vertical Integration Creates Dealer Lock-In: The Coverstar acquisitions and AI-powered "Measure by Latham" tool have transformed Latham from a component supplier into a full-system solution provider, with 25% of tool users being new dealers and cover sales surging 46% in Q2 2025, creating recurring revenue streams and deepening competitive moats.

• Sand States Represent Massive White Space: With Florida, Texas, Arizona, and California accounting for two-thirds of U.S. pool starts but fiberglass significantly underpenetrated in these markets, Latham's targeted strategy offers a multi-year growth runway independent of overall market recovery.

• Balance Sheet Deleveraging Amplifies Upside: Net debt leverage has compressed from 3.6x in Q1 2025 to 2.3x in Q3, with management targeting 2.0x by year-end, freeing up capacity for strategic investments while reducing financial risk in a cyclical industry.

Setting the Scene: The Only Pool Company That Owns the Homeowner Relationship

Latham Group, founded in 1956 and headquartered in Latham, New York, has spent 65 years building what management claims is "the most sought-after brand in the pool industry and the only pool company that has established a direct relationship with the homeowner." This direct-to-consumer marketing strategy, pioneered decades before digital channels became standard, creates a powerful demand-pull dynamic that bypasses traditional distribution dependencies and provides purchase-ready leads to dealer partners.

The company operates as a single segment but generates revenue across three product lines: in-ground swimming pools (47% of year-to-date sales), covers (28%), and liners (25%). This integration allows Latham to capture value across the entire pool lifecycle—from initial installation through replacement parts—while competitors typically specialize in one area. The business model leverages approximately 1,850 employees across 30 locations to maintain industry-leading lead times, a critical advantage when pool builders face labor shortages and project delays.

Latham's competitive positioning rests on two pillars: manufacturing scale in fiberglass pools and vertical integration across complementary products. Fiberglass pools represented 75% of Latham's in-ground pool sales in 2024, up from 73% in 2023, while the broader U.S. market only reached 24% penetration. This gap highlights both Latham's specialization and the remaining opportunity as the market continues shifting toward fiberglass.

Technology, Products, and Strategic Differentiation

The Fiberglass Economic Advantage

Fiberglass pools deliver tangible economic benefits that reshape the value proposition for builders and homeowners. Installers can complete six fiberglass installations in the time required for one concrete pool, using two-thirds fewer workers. This 6:1 efficiency ratio directly addresses the industry's top constraint: 46% of pool builders cite limited labor access as substantially impacting their ability to grow. For Latham, this translates into faster inventory turns, higher dealer satisfaction, and premium pricing power that concrete and vinyl competitors cannot replicate.

The product lineup itself creates a moat. Latham offers the broadest range of fiberglass pool configurations, widest price points, and most extensive specialty features including integrated spas and tanning ledges. This breadth enables Latham to serve everything from entry-level buyers to luxury custom homebuilders without ceding market share to niche competitors. In the Sand States—Florida, Texas, Arizona, and California—where fiberglass remains significantly underpenetrated relative to the 24% national average, this product breadth becomes a conversion tool for convincing concrete builders to switch allegiances.

Vertical Integration Through Coverstar and Measure by Latham

The August 2024 acquisition of Coverstar Central for $71.5 million vertically integrated Latham's automatic safety cover business across 29 states, immediately expanding adjusted EBITDA margins. Automatic safety covers represent a high-value attachment sale that enhances pool safety while generating substantial cost savings for homeowners through reduced water evaporation, lower heating costs, and decreased chemical usage. Management emphasizes these covers often pay for themselves within four to five years, creating a compelling value proposition that drives 15% year-over-year growth in Q3 2025.

The two smaller Coverstar dealer acquisitions in New York and Tennessee, completed in Q1 2025, further strengthened this position. Combined, these deals contributed $23.6 million to year-to-date cover sales growth while locking in dealer relationships that would otherwise represent potential competitive threats. Automatic safety covers are compatible with all pool types, significantly expanding Latham's addressable market beyond its own fiberglass installations.

The AI-powered "Measure by Latham" tool, rebranded as Measure Pro and Measure Go in Q3 2025, streamlines measurement and quoting for liners and covers from 2-4 hours to under 30 minutes. Critically, 25% of installers purchasing this tool are new to Latham, directly supporting market share expansion in both liners and safety covers. This technology investment creates a switching cost for dealers who become dependent on the efficiency gains, while the data collected through the tool provides Latham with insights into replacement cycles and regional demand patterns.

Sand States Strategy: The Multi-Year Growth Engine

The Sand States collectively account for approximately two-thirds of U.S. pool starts, yet fiberglass penetration remains well below the national average. Latham launched its targeted strategy in the second half of 2024, focusing on four pillars: expanding the dealer base by recruiting new builders and converting concrete installers, targeting master-planned communities, aligning product offerings with regional preferences for rectangular designs and pool-spa combos, and deploying targeted marketing campaigns.

Early results show traction. Florida sales grew at a high single-digit rate in Q3 2025, and Latham established partnerships with custom homebuilders featuring Latham fiberglass pools in several master-planned communities. The "Goosa" ad campaign in Texas and Florida generated over 40% more leads for dealers than the prior year. Success in the Sand States doesn't require overall market growth—Latham can gain share by converting concrete pool buyers to fiberglass, a structural shift that benefits from labor scarcity and speed-to-install advantages.

Financial Performance: Margin Expansion as Evidence of Structural Change

Q3 2025 Results Validate the Transformation

Latham's Q3 2025 results demonstrate the power of its restructured business model. Net sales increased 7.6% year-over-year to $161.9 million, significantly outpacing a U.S. in-ground pool market that management expects to be flat to slightly down from 2024 levels. This outperformance proves Latham can gain share even in a trough market, validating the strategic investments in fiberglass penetration and vertical integration.

Adjusted EBITDA surged 28.5% to $38.3 million, expanding margins by 390 basis points to 23.7%. This margin expansion occurred while gross margin improved 300 basis points to 35.4% and SG&A remained essentially flat at $28.6 million. The implication is clear: Latham's lean manufacturing and value engineering initiatives, which delivered $9 million in savings in 2024, have created a permanently lower cost structure that flows directly to the bottom line as volumes stabilize.

Net income jumped 37.7% to $8.1 million, despite a higher effective tax rate of 47.9% compared to just 0.7% in the prior year period. The tax rate increase stems from discrete stock-based compensation impacts and branch accounting for Latham Canada, not operational deterioration. For investors, this means the underlying business is generating substantially more cash than the headline numbers suggest, with operating cash flow reaching $51 million in Q3 alone.

Segment Dynamics Reveal the Growth Drivers

All three product lines grew in Q3 2025, a rare feat in a soft market. In-ground pool sales increased modestly by 0.8% to $75.4 million, with fiberglass momentum offsetting continued softness in packaged pools. Fiberglass is tracking to represent 75% of full-year 2025 in-ground pool sales, up from 73% in 2023, while initial analysis suggests fiberglass will capture another 1% of total market share to reach 24% of U.S. in-ground pool sales in 2025.

Cover sales led the portfolio with 15% growth to $54.9 million, driven by organic auto cover adoption and revenue synergies from the three Coverstar acquisitions. This growth is significant as auto covers generate higher margins than standard covers and create recurring revenue through replacement parts and seasonal servicing. The safety aspect resonates with consumers, particularly as 16 states now allow auto covers to substitute for fencing requirements.

Liner sales increased 13% to $31.6 million, attributed to industry-leading lead times and continued adoption of the Measure by Latham tool. Liners represent a replacement cycle business that provides stability during new construction downturns, with Latham's efficiency advantages allowing it to capture share from competitors who cannot match the 30-minute quoting capability.

Balance Sheet Strength Enables Strategic Flexibility

Latham's balance sheet transformation is equally impressive. Net debt leverage fell from 3.6x in Q1 2025 to 2.3x in Q3, with management targeting approximately 2.0x by year-end. The company repaid $25 million of revolver borrowings during the first nine months of 2025, leaving $75 million of availability on top of $70.5 million in cash. This deleveraging reduces financial risk in a cyclical industry while creating capacity for opportunistic acquisitions or accelerated investments when the market recovers.

Capital expenditures were revised downward to $22-24 million for the full year, down from the prior $27-33 million range, due to greater-than-expected efficiency of certain projects. This capital discipline demonstrates management's focus on returns rather than growth for growth's sake. The company has repaid $30-35 million of debt over the last 2.5 years, a track record that builds credibility for the long-term target of $750 million in net sales and $160 million in adjusted EBITDA when U.S. pool starts return to 2019 levels of 78,000.

Outlook, Management Guidance, and Execution Risk

2025 Guidance Reflects Confidence in Structural Gains

Management revised 2025 guidance upward in Q3, now expecting net sales of $540-550 million (7% growth at midpoint) and adjusted EBITDA of $92-98 million (19% growth at midpoint). This guidance assumes U.S. pool starts remain flat to slightly down from 2024 levels around 60,000-62,000, meaning all growth must come from market share gains and margin expansion. The implication is profound: Latham no longer needs a rising tide to lift its boat.

The EBITDA growth rate of 19% at the midpoint, nearly triple the sales growth rate, demonstrates the operating leverage inherent in the restructured business model. Management expects pricing to remain flattish, so margin expansion will come from continued lean manufacturing benefits, volume leverage in covers and liners, and the accretive impact of Coverstar acquisitions. This indicates the margin gains are structural, not cyclical.

Long-Term Vision: Doubling Revenue at Flat Market Volumes

Scott Rajeski's long-term vision statement frames the opportunity clearly: when U.S. pool starts return to 78,000 annually (2019 levels), Latham's structurally changed business model should enable $750 million in net sales and $160 million in adjusted EBITDA. This would represent more than double 2019 revenue and 2.5x EBITDA at the same market volume. The math implies that Latham expects to capture an additional $240 million in revenue through market share gains, product mix improvements, and vertical integration benefits even if the market never returns to its long-term average of 100,000 starts.

This vision is not speculative. The company has already demonstrated the ability to outperform in down markets, with 2024 in-ground pool sales declining only 13% compared to the estimated 15% drop in U.S. pool starts. The fiberglass penetration trend, which has gained six percentage points since 2021, provides a visible path to share gains. The Sand States strategy, if successful, could add hundreds of dealers and dozens of master-planned communities to Latham's ecosystem.

CEO Transition: Continuity with Fresh Perspective

The announced CEO transition, with Sean Gadd taking over on January 5, 2026, as Scott Rajeski retires, introduces execution risk but also opportunity. Rajeski will remain as a special advisor, ensuring continuity while Gadd brings fresh perspective. For investors, the key question is whether Gadd will maintain the disciplined capital allocation and operational focus that enabled the margin transformation, or pursue a more aggressive growth strategy that could dilute returns.

Risks and Asymmetries: What Could Break the Thesis

Tariff and Supply Chain Dynamics

Latham faces approximately $10 million in net tariff exposure after supply chain mitigation efforts, which management has offset with price increases implemented in June. Oliver Gloe stated the company feels "comfortable where we are, having mitigated the 2025 impact and at least as of today, also the run rate impact going forward." This demonstrates supply chain agility, but also highlights vulnerability to policy changes. If tariff rates increase or coverage broadens, Latham may need to absorb costs or risk pricing itself out of a price-sensitive market.

The company sources about $15 million in materials from tariff-impacted countries, representing a relatively small portion of cost of goods sold. However, indirect impacts from domestic steel and aluminum price spikes could pressure margins on non-fiberglass components. Management's ability to shift production between facilities and pre-stage inventory provides some buffer, but not immunity from sustained cost inflation.

Weather and Seasonal Volatility

Adverse weather conditions delayed pool building activity in Q2 2025, with management attributing $3-5 million in lost sales to weather impacts. This volatility is inherent to the outdoor construction industry but disproportionately affects Latham's quarterly results due to seasonality. The fourth quarter is typically the slowest period, creating potential for negative surprises in what should be a seasonally weak quarter. The risk is amplified in the Northeast, where Latham maintains significant operations and where weather delays can cascade into lost entire seasons for builders.

Market Cyclicality and Consumer Confidence

The pool industry remains highly cyclical, tied to new home construction and consumer discretionary spending. Scott Rajeski noted that consumer confidence to make the ultimate pool buying decision is "still lagging due to tariff uncertainty and I'd say interest rate uncertainty." With today's pool buyer primarily a cash purchaser, high interest rates and economic uncertainty could prolong the trough market conditions. If U.S. pool starts remain at 60,000 levels for multiple years rather than recovering to the 78,000 baseline, Latham's growth will depend entirely on market share gains, a more difficult path than riding a market recovery.

Competitive Pressure in Core Markets

While Latham claims leadership in every product category, competitors are not standing still. Pool Corporation (POOL) dominates distribution with 1,500+ sales centers and could favor competing manufacturers. Hayward (HAYW) and Pentair (PNR) compete in equipment and automation, potentially bundling their own solutions with pool installations. Leslie's (LESL) retail footprint provides direct consumer access that could bypass Latham's dealer network.

The fiberglass market itself is attracting new entrants as the segment grows, with low-cost imports potentially eroding pricing power. Latham's scale and manufacturing expertise provide defensive moats, but a price war in a down market could compress margins despite operational improvements.

Valuation Context: Pricing for Execution, Not Perfection

At $7.06 per share, Latham Group trades at an enterprise value of $1.07 billion, representing 2.1x trailing twelve-month revenue of $508.5 million and 11.3x adjusted EBITDA based on 2025 guidance. These multiples place SWIM at a discount to equipment-focused peers like Hayward (14.0x EBITDA, 3.2x sales) and Pentair (17.5x EBITDA, 4.2x sales), but at a premium to distributor Pool Corporation (16.1x EBITDA, 1.9x sales) on a revenue basis.

The valuation disconnect reflects Latham's manufacturing model and cyclical exposure. However, the company's price-to-operating cash flow ratio of 17.8x and price-to-free cash flow ratio of 34.5x suggest the market is pricing in continued execution of the margin expansion story. The absence of a dividend (0% payout ratio) and minimal share repurchases indicate management is prioritizing debt reduction and growth investments over capital returns, a prudent strategy for a cyclical business in recovery mode.

Latham's balance sheet strength—$70.5 million in cash, net debt leverage of 2.3x, and $75 million in untapped revolver capacity—provides downside protection that pure-play distributors or equipment manufacturers cannot match. The company's return on assets of 2.1% and return on equity of -2.7% reflect the recent trough market conditions, but the trajectory is clearly positive with Q3 net income up 37.7%.

Conclusion: A Structurally Better Business in a Cyclical Industry

Latham Group has engineered a fundamental transformation that allows it to thrive even when the pool market refuses to recover. The combination of fiberglass penetration gains, vertical integration through Coverstar, and a permanently lower cost structure has created a business that can deliver 19% EBITDA growth on 7% sales growth in a flat market. This operating leverage will amplify further when U.S. pool starts eventually recover from current trough levels of 60,000 toward the 78,000 baseline.

The critical variables to monitor are fiberglass market share gains in the Sand States and management's ability to maintain pricing discipline while expanding the dealer network. If Latham can increase its Sand States penetration from the current 17% of fiberglass sales toward the 24% national average, the long-term targets of $750 million in sales and $160 million in EBITDA become achievable even without a full market recovery.

The stock's valuation at 11.3x forward EBITDA and 2.1x sales does not fully reflect the structural improvements in the business model. While cyclical risks remain and the CEO transition introduces execution uncertainty, Latham's demonstrated ability to gain share, expand margins, and deleverage simultaneously suggests a compelling risk-reward profile for investors willing to endure potential volatility until the housing market stabilizes. The company's moats—manufacturing scale, direct-to-consumer marketing, and vertical integration—are stronger than ever, positioning SWIM to outperform when the cycle finally turns.
