Agreement and Plan of Merger financial

"Pursuant to the Agreement and Plan of Merger, dated as of April 18, 2026..."

An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.

Cash Consideration financial

"approximately $249.71 in cash and 10.211 shares of QXO common stock... (the "Cash Consideration");"

Cash consideration is the actual money paid to buy a company, asset, or stake rather than payment in shares or other forms. For investors it matters because cash payments deliver immediate, certain value and affect the buyer’s and seller’s cash reserves and balance sheets—like selling a car for cash versus taking a trade-in, one side gets instant spending power while the other changes its liquidity and risk profile.

Stock Consideration financial

"20.200 shares of QXO common stock (the "Stock Consideration")."

Stock consideration is when a company pays for an acquisition, merger, or other corporate deal by issuing its own shares instead of using cash. It matters to investors because receiving or issuing stock changes who owns what: sellers get a stake in the combined business and existing shareholders see their piece of the company shrink, similar to adding more slices to a pie. That shift affects potential returns, voting control, and future share value.

restricted stock unit ("RSU") awards financial

"Represents shares of TopBuild common stock underlying restricted stock unit ("RSU") awards."

performance-based stock unit ("PRSU") awards financial

"Represents shares of TopBuild common stock underlying performance-based stock unit ("PRSU") awards."

tax withholding financial

"Reflects tax withholding and performance share achievement on vesting."

Tax withholding is the practice of taking a portion of a payment—such as wages, dividends, or sale proceeds—before it reaches the recipient and sending that portion to the tax authority as an advance on the recipient’s eventual tax bill. For investors it matters because withholding reduces immediate cash received and affects after‑tax returns, estimated tax payments, and whether you may owe more or receive a refund when taxes are finally calculated, like having a small automatic savings set aside for your tax bill.
