On MDM’s 2026 Top Distributors List for Building Materials/Construction, QXO was No. 4 and TopBuild was No. 14. Upon completion, QXO has said the addition of TopBuild will make it the second-largest publicly traded building products distributor in North America, with more than $18 billion in combined revenue and over $2 billion in adjusted EBITDA.

QXO announced April 19 that it had reached an agreement to acquire TopBuild in a cash-and-stock transaction valued at approximately $17 billion. The deal is one of the largest ever in building materials distribution and follows QXO’s acquisition of Beacon in 2025 and its April 2026 closing of the $2.25 billion acquisition of Kodiak Building Partners.
