Item 5.07Submission of Matters to a Vote of Security Holders.

On June 29, 2026, at 9:00 a.m., Eastern Time, TopBuild Corp. (the “Company”) held a virtual special meeting of the Company’s stockholders (the “Special Meeting”). At the Special Meeting, the Company’s stockholders voted on and approved a proposal (the “TopBuild Merger Proposal”) to adopt the Agreement and Plan of Merger, dated as of April 18, 2026 (the “Merger Agreement”), by and among the Company, QXO, Inc., a Delaware corporation (“QXO”), Titanium MergerCo, Inc., a Delaware corporation and a wholly owned subsidiary of QXO (“Titanium Merger Sub”), and Titanium MergerCo 2, LLC, a Delaware limited liability company and a wholly owned subsidiary of QXO (“Forward Merger Sub”), pursuant to which, subject to the terms and conditions set forth therein, (a) Titanium Merger Sub will merge with and into the Company, with the Company surviving as a wholly owned subsidiary of QXO (the “Titanium Merger”), and (b) immediately following the Titanium Merger, the Company will merge with and into Forward Merger Sub, with Forward Merger Sub continuing as the surviving company (together with the Titanium Merger, the “Mergers”). Prior to the Special Meeting, the Company delivered a definitive joint proxy statement/prospectus (the “Joint Proxy Statement/Prospectus”) to its stockholders describing (i) the Special Meeting, (ii) the Mergers, (iii) the TopBuild Merger Proposal, (iv) a proposal to approve, on a non-binding advisory basis, the compensation that may be paid or become payable to the Company’s named executive officers in connection with the Mergers and as contemplated by the Merger Agreement (the “TopBuild Compensation Proposal”), (v) a proposal to adjourn the Special Meeting, if necessary or appropriate, to solicit additional proxies if there were not sufficient votes to adopt the Merger Agreement at the time of the Special Meeting (the “TopBuild Adjournment Proposal”) and (vi) related information. The Joint Proxy Statement/Prospectus was filed with the U.S. Securities and Exchange Commission on May 29, 2026.

As of the close of business on May 26, 2026, the record date for the Special Meeting, there were 28,024,568 shares of the Company’s common stock issued and outstanding. At the Special Meeting, 23,451,576 shares of the Company’s common stock were represented by proxy or by attending the Special Meeting, representing approximately 84% of the Company’s common stock outstanding as of the record date, which constituted a quorum to conduct business at the Special Meeting. Virtual attendance at the Special Meeting constituted presence in person for purposes of satisfying the quorum and voting requirements. The following are the final voting results on the TopBuild Merger Proposal, the TopBuild Compensation Proposal and the TopBuild Adjournment Proposal, each of which is more fully described in the Joint Proxy Statement/Prospectus.

TopBuild Merger Proposal: The number of shares voted “For” or “Against,” as well as abstentions, with respect to the TopBuild Merger Proposal presented at the Special Meeting were:

TopBuild Compensation Proposal: The number of shares voted “For” or “Against,” as well as abstentions, with respect to the TopBuild Compensation Proposal presented at the Special Meeting were:  

TopBuild Adjournment Proposal: The number of shares voted “For” or “Against,” as well as abstentions, with respect to the TopBuild Adjournment Proposal presented at the Special Meeting were:  

With respect to the TopBuild Adjournment Proposal, although the TopBuild Adjournment Proposal would have received sufficient votes to be approved, no motion was made because the adjournment of the Special Meeting was determined not to be necessary or appropriate.

Because each of the TopBuild Merger Proposal, the TopBuild Compensation Proposal and the TopBuild Adjournment Proposal were “non-routine” under applicable rules of the New York Stock Exchange, brokers, banks and other nominees did not have discretionary authority to vote on any such proposals and were not able to vote on any such proposals absent instructions from the beneficial owner. Accordingly, there were not any broker non-votes at the Special Meeting.
