SiteOne (SITE) Q3 2025: Gross Margin Expands 70bps as Private Label and Branch Optimization Drive Resilience
Gross margin and SG&A leverage improved meaningfully despite persistent end market softness, as SiteOne’s commercial and operational initiatives offset residential construction headwinds. Strategic focus on private label, small customer growth, and digital engagement continues to underpin share gains and margin expansion, positioning the business for further improvement even if demand remains subdued into 2026.
Summary
- Margin Expansion Outpaces Volume: SiteOne’s pricing, private label, and cost controls drove gross margin and SG&A leverage in a soft market.
- Branch Optimization Accelerates: Proactive closures and focus branch improvements are set to deliver further cost efficiency in 2026.
- Digital and Private Label Traction: Digital sales and private label brands are scaling rapidly, providing durable levers for future share gains.
Performance Analysis
SiteOne delivered 4% net sales growth in Q3 2025, with organic daily sales up 3% and acquisition-driven growth contributing an additional point. Gross profit increased 6%, with gross margin expanding 70 basis points to 34.7%, reflecting stronger price realization and benefits from commercial initiatives, particularly private label and small customer growth. SG&A as a percentage of net sales declined by 50 basis points to 28.4%, underpinned by disciplined cost management and productivity gains.
The company’s adjusted EBITDA rose 11%, and margin improved by 60 basis points to 10.1%. Notably, digital sales more than doubled year-to-date, and private label brands such as ProTrade, Solstice Stone, and Portfolio grew by 50% in the quarter. Branch optimization efforts continued, with 22 locations consolidated or closed in 2024 and plans for an additional 15 to 20 closures in Q4 2025, targeting further SG&A leverage.
- Gross Margin Lift: Price discipline and private label mix contributed to margin gains despite commodity deflation in grass seed and PVC pipe.
- SG&A Leverage: Cost controls and delivery productivity initiatives reduced expenses, with focus branches showing over 200 basis points of margin improvement.
- Digital Engagement: SiteOne.com and digital tools accelerated sales growth, adding thousands of new regular users and boosting associate productivity.
Despite persistent softness in new residential construction and repair/upgrade markets, SiteOne’s diversified end-market exposure and commercial execution enabled continued outperformance relative to underlying market demand.

Strategic Positioning
1. Private Label and Small Customer Expansion
Private label penetration rose to 15% of sales, with management targeting a long-term goal of 25% to 30%. Small customer initiatives are accelerating, with digital marketing and bilingual branch expansion capturing market share in a historically underpenetrated segment. Both strategies provide margin tailwinds and a multi-year runway for above-market growth.
2. Digital Platform and Productivity
SiteOne’s digital sales grew over 125% year-to-date, and digital engagement is driving higher customer growth rates and improved salesforce productivity. CRM adoption and disciplined revenue-generating habits among over 600 outside sales associates enabled 10% more revenue coverage without headcount increases, supporting scalable growth at lower cost.
3. Network Optimization and Cost Structure
Branch consolidation and focus branch improvement remain central to SG&A leverage. With 22 closures in 2024 and another 15-20 planned, management expects to retain most sales while reducing costs. Focus branches (20% of revenue) improved adjusted EBITDA margin by over 200 basis points in 2025, and further gains are expected as underperforming locations are brought to company average.
4. Acquisition Strategy and Market Fragmentation
SiteOne added four companies in Q3 and October, but 2025 is a lighter year for acquired revenue ($40 million YTD), reflecting a focus on smaller targets amid a fragmented landscape. Management reiterated a robust pipeline and expects acquisition activity to rebound in 2026, with a preference for well-run businesses over turnaround projects like Pioneer.
5. End-Market Diversification
With maintenance, repair/upgrade, and new construction segments representing 65%, 30%, and 35% of sales respectively, SiteOne’s balanced portfolio buffers against cyclical volatility. Maintenance demand remains steady, while repair/upgrade appears to be stabilizing, and commercial construction is flat. This diversification supports resilience and positions the company for upside as market conditions improve.
Key Considerations
SiteOne’s Q3 results highlight a business executing well on self-help levers while end markets remain challenging. Investors should weigh the durability of these initiatives and their ability to sustain margin expansion in a low-growth environment.
Key Considerations:
- Private Label and Digital Leverage: Sustained growth in these areas is critical for ongoing margin and share gains, with management targeting significant further penetration.
- Branch Optimization as Margin Catalyst: Further closures and focus branch improvements are expected to drive SG&A leverage into 2026, even if volume remains soft.
- Acquisition Pipeline and Capital Allocation: With lower acquisition activity in 2025 and leverage at the low end of target, share repurchases are likely to increase if M&A remains muted.
- End-Market Exposure: Continued weakness in residential construction and repair/upgrade is partially offset by stability in maintenance and commercial segments.
Risks
Persistent softness in residential construction and consumer confidence, coupled with elevated interest rates, could prolong volume headwinds. Commodity price swings and competitive pricing pressure may challenge gross margin gains, while acquisition execution risk remains if larger, well-run targets become scarce. Branch consolidation charges and execution risk around retaining sales post-closure are additional considerations.
Forward Outlook
For Q4 2025, SiteOne guided to:
- Low single-digit organic daily sales growth, driven by commercial initiatives and modest price inflation
- Continued SG&A leverage and adjusted EBITDA margin expansion, despite a $4 million to $6 million charge related to branch closures
For full-year 2025, management expects:
- Adjusted EBITDA of $405 million to $415 million (excluding unannounced acquisitions)
Management noted ongoing market uncertainty, but sees positive organic sales growth, modest price inflation, and further operating leverage as achievable, with acquisition activity likely to rebound in 2026.
- Stable maintenance and commercial demand underpin resilience
- Repair/upgrade market appears to have stabilized, offering potential for future growth
Takeaways
SiteOne’s execution on margin, cost, and digital initiatives is offsetting weak end market demand, providing a template for margin expansion even in a tepid growth environment.
- Margin Expansion Is Self-Help Driven: Private label, digital sales, and branch optimization are delivering tangible gains, with further runway ahead.
- Acquisition Slowdown Is Temporary: A robust pipeline and balance sheet flexibility position SiteOne to accelerate M&A when the market allows.
- Watch for End-Market Turn and Execution on Closures: Stabilization in repair/upgrade and potential housing recovery could provide upside, but execution on branch consolidation and retention of sales is key.
Conclusion
SiteOne’s Q3 results underscore the power of operational discipline and strategic self-help levers in navigating soft demand. With margin expansion, digital and private label momentum, and a diversified end-market mix, the business is positioned for further gains even if macro conditions remain challenging into 2026.
Industry Read-Through
SiteOne’s results highlight a broader trend among distributors and value-added resellers: Margin expansion and outperformance are increasingly driven by private label, digital adoption, and cost optimization, rather than pure volume growth. Fragmented industries with local scale advantages remain ripe for consolidation, but the pace of M&A may ebb and flow with market cycles and target availability. Competitors in building products, maintenance supply, and specialty distribution should note the resilience provided by diversified end-markets and the critical role of digital engagement and private label in driving margin and share gains.
