QXO to Buy TopBuild for $17 Billion, Creating $18B Revenue Group

QXO announced it has entered into a definitive agreement to acquire insulation and building-products installer TopBuild for approximately $17 billion in a cash-and-stock transaction, marking the largest acquisition in QXO’s roll-up strategy to date.

Under the terms, TopBuild shares are valued at $505 each, implying a roughly 23% premium to the company’s recent closing price; shareholders may elect $505 in cash or 20.2 shares of QXO common stock per TopBuild share, subject to proration. The consideration mix is targeted at approximately 45% cash and 55% stock, and the deal is expected to close in the third quarter of 2026, pending shareholder and customary regulatory approvals.

QXO said the combined company will have more than $18 billion of revenue and over $2 billion of combined adjusted EBITDA, with estimated integration synergies of about $300 million by 2030. Market commentary has focused on the premium paid to TopBuild shareholders and the strategic fit that adds insulation installation and specialty distribution capabilities to QXO’s existing roofing, waterproofing and lumber platforms.

The transaction is part of a broader consolidation wave in North American building-products distribution. QXO’s prior deals, including Beacon and Kodiak, accelerated scale expansion; adding TopBuild further increases geographic coverage, product depth and service offerings. Observers note that realization of procurement savings, logistics optimization and cross-selling will determine the accrual of the projected synergies.

Analysts expect short-term volatility as the market prices financing, dilution and integration risk, but many see potential long-term value if QXO delivers on cost and revenue synergies and manages leverage. Key milestones to watch are shareholder votes, regulatory clearances and the pace at which QXO converts projected synergies into measurable earnings.
