ROSWELL, Ga. — (BUSINESS WIRE) — SiteOne Landscape Supply, Inc. (the “Company” or “SiteOne”) (NYSE: SITE) announced earnings for its first quarter ended March 29, 2026 (“First Quarter 2026”).

“We are pleased with our first quarter performance as we more than offset the weather and market-related softness in sales volume and delivered Adjusted EBITDA growth with meaningful gross margin improvement and continued tight SG&A management,” said Doug Black, Chairman and CEO of SiteOne. “Our teams are executing our commercial and operational initiatives well, which is allowing us to gain market share and expand our Adjusted EBITDA margin. During the quarter, we were also very pleased to complete the acquisition of Reinders, a strong fifth-generation market leader in the Midwest, displaying the power of our acquisition strategy. Looking ahead, we remain confident in our ability to navigate the near-term challenges, deliver superior value to our customers and suppliers, and execute our strategy to drive sustained performance and growth for shareholders.”

First Quarter 2026 Results

Net sales for the First Quarter 2026 increased $0.7 million to $940.1 million compared to $939.4 million for the prior year period. Organic Daily Sales decreased 1% compared to the prior year period, primarily due to unfavorable weather conditions across several regions, which resulted in lower volumes. While pricing was positive, lower sales volume drove the year-over-year decline in Organic Daily Sales. Acquisitions contributed $12.4 million, or 1%, to Net sales growth for the quarter.

Gross profit increased 3% to $318.8 million for the First Quarter 2026 compared to $309.8 million for the prior year period. Gross margin improved 90 basis points to 33.9%, driven by higher price realization and continued benefits from commercial initiatives, partially offset by freight and distribution costs as well as deflation in certain commodity products.

Selling, general and administrative expenses (“SG&A”) for the First Quarter 2026 increased to $349.9 million from $343.2 million for the prior year period. SG&A as a percentage of Net sales increased 70 basis points to 37.2% due primarily to the decrease in Organic Daily Sales during the quarter. SG&A in the Base Business on an adjusted basis was flat for the first quarter compared to the prior year period.

Net loss attributable to SiteOne for the First Quarter 2026 was $26.6 million, compared to $27.3 million for the prior year period, reflecting higher gross margin, partially offset by lower sales volume and higher SG&A.

Adjusted EBITDA1 for the First Quarter 2026 increased 14% to $25.5 million, compared to $22.4 million for the prior year period. Adjusted EBITDA margin improved 30 basis points to 2.7%.

Net debt, calculated as long-term debt (net of issuance costs and discounts) plus finance leases, net of Cash and cash equivalents on our balance sheet as of March 29, 2026, was $584.5 million compared to $580.4 million as of March 30, 2025. Net debt to Adjusted EBITDA1 for the last twelve months was 1.4 times compared to 1.5 times for the prior year period.

As of March 29, 2026, Cash and cash equivalents were $84.0 million and available capacity under the ABL Facility was $418.1 million.

1.Adjusted EBITDA includes contribution from non-controlling interest of $0.7 million for the First Quarter 2026.

Outlook

“We achieved 3% growth in pricing during the quarter, and we expect overall prices in 2026 to increase 2% to 3% for the full year,” Doug Black continued. “Due to unfavorable weather, the Spring selling season started later this year than in 2025 and we have seen improved sales volume in April so far. In terms of end markets, we believe that the recent increase in macroeconomic uncertainty is negatively affecting the already weak new residential construction and the more resilient repair and upgrade end markets, more than offsetting maintenance growth and solid demand in new commer
