Item 1.01Entry into a Material Definitive Agreement.

Merger Agreement

On April 18, 2026, TopBuild Corp., a Delaware corporation (“TopBuild”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with QXO, Inc., a Delaware corporation (“QXO”), Titanium MergerCo, Inc., a Delaware corporation and wholly owned subsidiary of QXO (“Titanium Merger Sub”), and Titanium MergerCo 2, LLC, a Delaware limited liability company and wholly owned subsidiary of QXO (“Forward Merger Sub”).

The TopBuild board has unanimously approved the Merger Agreement and has recommended that the stockholders of TopBuild adopt the Merger Agreement. The QXO board has unanimously approved the Merger Agreement and resolved to recommend the approval of the issuance of shares of common stock, par value $0.00001 per share, of QXO (the “QXO Shares”) pursuant to the Merger Agreement (the “QXO Share Issuance”) to QXO’s stockholders.

The Mergers. Pursuant to the Merger Agreement, and subject to the satisfaction or waiver of certain customary conditions set forth therein, (i) Titanium Merger Sub will be merged with and into TopBuild (the “Titanium Merger”), with TopBuild surviving the Titanium Merger as a wholly owned subsidiary of QXO and (ii) immediately thereafter, TopBuild will be merged with and into Forward Merger Sub (the “Forward Merger” and, together with the Titanium Merger, the “Mergers”), with Forward Merger Sub surviving the Forward Merger as a wholly owned subsidiary of QXO.

Merger Consideration. Pursuant to the Merger Agreement, at the effective time of the Titanium Merger (the “Titanium Merger Effective Time”), each share of common stock, par value $0.01 per share, of TopBuild (the “TopBuild Shares”) issued and outstanding immediately prior to the Titanium Merger Effective Time (other than (i) TopBuild Shares owned by QXO, Titanium Merger Sub, Forward Merger Sub or any other wholly owned subsidiary of QXO, (ii) TopBuild Shares held in treasury or held by any wholly owned subsidiary of TopBuild (each of the TopBuild Shares in clauses (i) and (ii), a “Cancelled Share” and collectively, “Cancelled Shares”) and (iii) TopBuild Shares held by stockholders of TopBuild who have validly exercised their appraisal rights under the Delaware General Corporation Law), will be automatically converted into the right to receive, pursuant to a properly made election that has actually been received by the exchange agent and not revoked prior to the election deadline to be determined by QXO and TopBuild, and subject to the election and proration procedures set forth in the Merger Agreement, one of the following forms of consideration: (i) an amount in cash equal to $505.00 (the “Cash Consideration”) or (ii) 20.200 QXO Shares (the “Stock Consideration”). TopBuild Shares in respect of which no cash election or stock election is validly made will be deemed to be TopBuild Shares in respect of which stock elections have been made.

The maximum number of TopBuild Shares to be converted into the right to receive the Cash Consideration will be equal to forty-five percent (45%) of the aggregate number of TopBuild Shares issued and outstanding immediately prior to the Titanium Merger Effective Time (other than Cancelled Shares). The maximum number of TopBuild Shares to be converted into the right to receive the Stock Consideration will be equal to fifty-five percent (55%) of the aggregate number of TopBuild Shares issued and outstanding immediately prior to the Titanium Merger Effective Time (other than Cancelled Shares), which maximum number may be increased (but not decreased) by QXO in its sole discretion. As a result, the form of consideration a TopBuild stockholder elects to receive may be adjusted pursuant to the proration procedures set forth in the Merger Agreement such that such TopBuild stockholder may receive, in part, a different form of consideration than the form of consideration elected.

Treatment of Outstanding Equity Awards. Pursuant to the terms of the Merger Agreement:

Representations, Warranties and Covenants; Non-Solicit; Board Representation. The Merger Agreement contains customary representations, warranties and covenants of TopBuild, QXO, Titanium Merger Sub and Forward Merger Sub, including, among others, covenants by each of TopBuild and QXO regarding the conduct of its business during the pendency of the transactions contemplated by the Merger Agreement and other matters. QXO, TopBuild and their affiliates and representatives are required, among other things, not to solicit alternative acquisition proposals and, subject to certain customary exceptions, not to engage in, authorize or knowingly permit discussions or negotiations regarding an alternative acquisition proposal.

The Merger Agreement also provides that prior to the Titanium Merger Effective Time, QXO will increase the size of its board in order to cause one current member of the TopBuild board to be appointed to the QXO board at the Titanium Merger Effective Time.

Termination; Termination Fee. The Merger Agreement contains certain customary termination rights in favor of each of TopBuild and QXO, including among others, if (i) the QXO Stockholder Approval or the TopBuild Stockholder Approval is not obtained, (ii) prior to the stockholder meeting of the other party, the QXO board or the TopBuild board, as applicable, has changed its recommendation in connection with the Mergers, or has failed to make or reaffirm such recommendation in certain circumstances and (iii) prior to the stockholder meeting of the other party, such party materially breaches its covenants not to solicit alternative proposals. In addition, either TopBuild or QXO may terminate the Merger Agreement if, subject to certain limitations, the Titanium Merger has not been consummated by January 17, 2027.  In addition, the Merger Agreement provides that TopBuild and QXO, as the case may be, is obligated to pay the other party a termination fee equal to $600 million in cash under specified circumstances, including in the event (1) the Merger Agreement is terminated by the other party prior to the receipt of such party’s required stockholder approval because such party materially breached its covenants not to solicit alternative proposals, (2) the Merger Agreement is terminated by the other party prior to the stockholder meeting of the other party, in the event the QXO board or the TopBuild board, as applicable, has changed its recommendation in connection with the Mergers, or has failed to make or reaffirm such recommendation in certain circumstances or (3) in certain circumstances, the Merger Agreement is terminated and on or after the date of the Merger Agreement and prior to such termination an acquisition proposal was publicly announced (and not publicly withdrawn) and TopBuild or QXO, as applicable, enters into a definitive agreement with respect to, or consummates the transactions contemplated by, an acquisition proposal within 12 months following such termination.
