Beacon Issues Statement in Response to QXO’s Extension of Unsolicited Tender Offer

Beacon Board Has Unanimously Recommended That
Beacon Shareholders NOT Tender Their Shares Into QXO’s Offer

HERNDON, Va., February 25, 2025 — Beacon (Nasdaq: BECN) (the “Company”) today issued the following statement regarding QXO, Inc.’s (NYSE: QXO) extension of its unsolicited tender offer to acquire all outstanding shares of Beacon common stock for $124.25 per share in cash and QXO’s statement that approximately 10,685,631 shares of Beacon common stock, which represents approximately 17.27% of all issued and outstanding shares, have tendered into the offer:

Beacon’s Board of Directors (the “Board”) has unanimously concluded that QXO’s unsolicited tender offer (the “Offer”) significantly undervalues the Company and its prospects for growth and value creation, and is not in the best interests of Beacon and its shareholders. Beacon has a strong track record of delivering above market growth and superior financial and operational results through the successful execution of Ambition 2025. Having generated total shareholder returns of more than 200% during the past five years1 under the current management team, the Board is confident that Beacon’s standalone plan will deliver substantially greater value than QXO’s proposal.

In addition, the fact that shareholders have only tendered approximately 17.27% of shares reaffirms that, consistent with the Board’s view, the Offer is at a price that the vast majority of shareholders believe does not adequately capture Beacon’s full intrinsic value.

We appreciate the support we have received and continue to encourage all Beacon shareholders not to tender their shares into the Offer. We similarly encourage those who have tendered to withdraw their shares.

J.P. Morgan is serving as financial advisor to the Company and its Board, and Lazard is serving as financial advisor to the Board. Sidley Austin LLP and Simpson Thacher & Bartlett LLP are serving as legal advisors to Beacon.

Exhibit (a)(18)

Team Beacon,

As you may have seen, QXO announced today that in the four weeks since they launched a tender offer on January 27, only ~17% of Beacon shareholders have tendered into their offer. As a result, QXO extended the time period for its unsolicited tender offer to acquire Beacon until March 3.

I felt it was important to note this result because it is a testament to the hard work, dedication, and contributions you make to Beacon. Clearly, a significant majority of our shareholders believe that we are on the right track, that our future is bright, and that the offer is at a price that does not capture our full intrinsic value. That is thanks in large part to you putting customers at the center of our business and delivering for them and the company every day.

In response to QXO’s announced extension, the Company issued a response reiterating that the Board continues to believe that QXO’s offer significantly undervalues our prospects for growth and value creation. The Board is also confident that our standalone plan will deliver substantially greater value than QXO’s proposal. As such, the Board continues to encourage shareholders not to tender into QXO’s offer.

In terms of what’s ahead, we’re looking forward to issuing our earnings results for the fourth quarter and full year 2024 on Thursday, as well as preparing for our Investor Day on March 13. We will also hold our annual meeting of shareholders, which has yet to be scheduled. As previously mentioned in the video I recently shared, the Board is continuing to evaluate QXO’s director nominees and will present its recommendation to shareholders in our upcoming proxy statement.

As always, please direct any outside inquiry to Jennifer Lewis at corporatecommunications@becn.com, and remain vigilant with respect to any unusual requests.

Thank you for all that you do to live our mission — helping our teammates, customers, and partners BUILD MORE.
