Home Depot is the world's largest home improvement retailer, operating 2,359 big-box stores averaging ~104,000 square feet across the U.S., Canada, and Mexico, stocking 30,000–40,000 SKUs across lumber, building materials, plumbing, electrical, flooring, paint, appliances, tools, and lawn and garden. Home Depot serves two primary customer groups: DIY consumers and professional contractors (Pros). Pros are a key growth priority, and Home Depot has built a "Pro ecosystem" including a dedicated outside sales force, job-site delivery, trade credit, order management tools, and a B2B digital platform. Home Depot also captures Do-It-For-Me (DIFM) demand by selling installation services to homeowners while supplying the Pros who do the work. The retail business runs on an everyday low price model, where profitability is highly sensitive to comparable store sales growth, which drives operating leverage on a largely fixed cost base. In fiscal 2024, Home Depot acquired SRS Distribution, a specialty trade distributor with over 1,250 branch locations serving professional roofers, landscapers, and pool contractors; SRS subsequently acquired GMS, adding drywall and interior building products distribution. SRS operates as a wholesale distributor with lower gross margins but also lower operating costs than retail. Home Depot also operates HD Supply, which provides MRO products to multifamily, hospitality, and healthcare facilities. Online sales are deeply integrated with stores, with ~50% of U.S. online orders fulfilled through physical locations. Home Depot's long-term growth strategy centers on expanding its Pro business, growing its interconnected digital and delivery capabilities, and opening new stores.
