QXO is a building products distributor, operating through its subsidiary QXO Building Products (formerly Beacon Roofing Supply), acquired in April 2025. QXO Building Products is the largest publicly traded distributor of roofing, waterproofing, and complementary building products in North America, with roughly 600 branches across the U.S. and Canada serving over 110,000 customers. The core business is buying roofing and building products from manufacturers in bulk and reselling them to professional contractors at a markup, with gross margins running around 25–26%. The primary products are asphalt shingles for residential customers and single-ply membranes and insulation for commercial customers, with complementary products including waterproofing, siding, and windows and doors rounding out the portfolio. Roughly 80% of roofing industry volume comes from repair and re-roofing, of which the vast majority is non-discretionary, driven by weather damage and deterioration. QXO Building Products sells through a direct field sales force, its own logistics and delivery network, and a growing digital platform that accounted for roughly 16% of sales as of late 2024. Margin is enhanced by private label products under the TRI-BUILT brand and digital channel sales, both of which carry meaningfully higher margins than standard offline branded sales. QXO was purpose-built as an acquisition vehicle by CEO Brad Jacobs, targeting $50B in annual revenues within a decade through operational improvement, organic growth, and aggressive M&A in the highly fragmented building products distribution industry.
