SiteOne Landscape Supply is the only national full-product-line wholesale distributor of landscape supplies in the U.S., with additional presence in Canada. SiteOne buys landscape products from manufacturers and resells them to professional landscape contractors — primarily small, private firms — at a markup. SiteOne serves over 440,000 customers across a network of over 670 branches in 45 U.S. states and five Canadian provinces, supported by a fleet of over 2,600 delivery vehicles. SiteOne carries roughly 180,000 SKUs across categories including nursery goods, hardscapes, irrigation supplies, fertilizer and control products, landscape accessories, and outdoor lighting. Proprietary brands, led by LESCO (fertilizers, control products, and turf seed), account for roughly 15% of sales. SiteOne pursues three growth levers: organic growth by targeting underserved small customers and expanding private label penetration (targeting 25-30% of sales long term, from 15% today); acquisitions in a highly fragmented market where SiteOne estimates it holds only ~19% share; and operational improvements including branch network optimization and logistics efficiency. SiteOne has completed 107 acquisitions since 2014. The business is highly seasonal, with the second and third quarters driving the vast majority of revenue and nearly all annual profitability.
