QXO, Inc. (QXO) stock intrinsic value fair value estimate & owner earnings analysis

QXO is now one of North America's largest building-products businesses, assembled in fifteen months. It bought Beacon Roofing Supply (roofing, siding and waterproofing distribution through about 600 branches in all 50 states and seven Canadian provinces) on April 29, 2025; Kodiak Building Partners (lumber, trusses, windows, doors and roofing through about 110 locations in 26 states, roughly 40% of sales in Florida and Texas) on April 1, 2026 for about $2.2 billion; and TopBuild (the largest U.S. installer and distributor of insulation and related products, about $5.4 billion of 2025 sales) on July 1, 2026 for about $15 billion, paid with roughly 312 million new QXO shares plus cash. Before 2024 the company was a small software reseller, so its earlier history says nothing about today's business. What the business earns. Because the combined business has never reported a full year, we built its cash earnings from the three parts' own audited cash-flow statements, counting operating cash flow less swings in receivables, inventory and payables, less stock compensation and capital spending, and adding back interest paid (the lenders are subtracted separately below). TopBuild produced about $655 million on that basis in 2025 and about $718 million in 2024, or roughly $750 million before interest. Beacon under QXO produced $95 million in its first eight months, after $188 million of deal, restructuring and transformation costs and net of $126 million of interest earned on cash QXO has since spent; before interest and those one-time costs that is about $300 million for eight months, consistent with Beacon's own record as a standalone company (about $120 million to $600 million a year before interest in 2022 to 2024, a wide swing). We put Beacon at about $400 million a year and Kodiak at about $80 million (its roughly $2.4 billion of sales at Beacon's cash margin), less about $80 million of corporate stock compensation beyond what the acquired companies already paid. That gives about $1.15 billion a year before interest. This is a judgement, not a reported number: the one-time costs are treated as one-time, and restructuring was still running in the first half of 2026 ($24 million). Reported losses ($279 million in 2025, $366 million in the first half of 2026 before preferred dividends) are driven largely by amortization of acquired customer lists and trade names, about $315 million in 2025 and rising sharply with TopBuild. That charge is not deducted here, but because those intangibles wear out, no growth is credited in the base case. Near-term path. On a like-for-like basis the businesses shrank in 2025: Beacon's combined sales fell 2.9% and TopBuild's cash earnings fell about 9% while its sales rose 1.5% only because of acquisitions. Recent results show no recovery. The base case therefore starts with a 4% decline in year one, at or below the recent trend, and then holds flat. What it owes. After the TopBuild closing: about $6.0 billion of debt at June 30, 2026 (including a $2.25 billion 6.75% senior secured note and a term loan, both due April 2032, and $3.0 billion of new 6.50% notes due 2031 and 6.875% notes due 2034 that were held in escrow until the deal closed), plus a $3.0 billion incremental term loan drawn at closing, about $0.2 billion of finance leases and a small revolver balance, for about $9.3 billion. We assume the June cash ($2.8 billion plus the $3.0 billion escrow) was consumed by the TopBuild cash payment and the refinancing of TopBuild's debt. Ahead of the common also sit $1.0 billion of 9% Convertible Preferred Stock (convertible at $4.566 into 219 million shares, with 219 million warrants at $4.566 to $13.698), $3.0 billion of 4.75% Series C perpetual convertible preferred issued to Apollo-led investors ($2.0 billion for Kodiak and $1.0 billion at the TopBuild closing; convertible at $23.25), and a 5.5% mandatory convertible preferred that turns into up to about 35 million shares by 2028. Each preferred is counted at whichever is worth more: its cost carried in perpetuity or the shares it converts into. Per-share figures start from about 1,114 million shares (1,037.5 million outstanding in August 2026, 42 million pre-funded warrants and the mandatory conversion), plus warrants and conversions where a case makes them worthwhile. Base case: about $4.69 per share. Earnings before interest of about $1.10 billion a year, flat for the life of the story, because a 95-year-old roofing distributor and a national insulation installer with long-standing builder relationships keep serving the same trades. The business is worth about $18.4 billion; it owes about $9.3 billion of debt and about $3.9 billion of preferred, leaving about $5.2 billion for common holders once the 9% preferred converts. Not credited: the roughly $300 million of TopBuild synergies, management's targets, further acquisitions, and any margin gains, because none has yet shown up in results. Bull case: about $8.52 per share. Earnings start at about $1.28 billion, reflecting Beacon earning toward its 2023 level and Kodiak's full contribution, and grow 2% a year for six years from small tuck-in acquisitions of the kind TopBuild and Beacon each made steadily for over a decade, then hold. The business is worth about $23.5 billion against the same debt and preferred. The Series C does not convert in this case. Bear case: about -$0.49 per share. Earnings fall about 13% in year one, then a housing and re-roofing downturn arrives in years two to four: we use the 2007 to 2011 U.S. housing collapse, when new-home construction fell by roughly three quarters and installers and distributors swung to losses, scaled down because about half of Beacon's sales are repair and re-roofing, which held up better. Cash earnings before interest fall to about $250 million a year at the trough, well below the roughly $610 million annual interest bill, so the company would burn cash for three years and would likely need covenant relief, asset sales or new equity. Recovery to about $900 million takes until year seven. We also charge about two percentage points of extra interest on refinancing the 2031 and 2032 maturities. The business is worth about $13.3 billion against about $10.0 billion of debt including that penalty and about $3.9 billion of preferred: the company would owe roughly $0.5 billion more than the business is worth, and the common would likely be worth nothing. Testing the case. We challenged the size of TopBuild's contribution against its 2025 annual report: operating cash flow of $756 million, capital spending of $59 million, stock compensation of $17 million and a $26 million working-capital release, which confirms about $655 million after interest. We also rebuilt QXO's 2025 cash flow from the net loss plus non-cash charges, and it matched operating cash flow before working capital. Items we could not reconcile from the filings: the exact cash paid for TopBuild, whether all of TopBuild's $1.25 billion of notes were tendered, the term and price of the $3.0 billion incremental term loan, and the first-half 2026 working-capital detail. Our previous figures (bear -$2.87, base $1.17, bull $3.66) described a business without TopBuild and with only part of Kodiak, and carried $3.0 billion of notes for which the acquisition they funded had not yet been counted; they are not comparable with these. The common pays no dividend; about $380 million a year of preferred dividends rank ahead of it. Margin of safety judgement. We are moderately sure of TopBuild's earnings, which rest on years of audited cash flow, and much less sure of Beacon's, which swung widely before QXO bought it and has not yet shown a clean year since. The worst plausible outcome is a housing downturn arriving while the company carries about $9.3 billion of debt and $3.9 billion of preferred; the debt is not due until 2031 to 2034, which buys time, but interest and preferred dividends come first and three lean years would almost certainly force dilution. If Beacon's true level is $250 million rather than $400 million, the base value falls by roughly $1.30 a share; if the integration costs keep recurring at 2025's pace, it falls by roughly another $1.50. The common pays nothing during the holding period, and the price assumes a holding period of three years or more. The margin-of-safety price is $2.50 a share: from that price, the base case of steady earnings with no growth implies roughly a doubling in about three and a half years, while the bear case implies the common would most likely be wiped out, so the margin-of-safety price has to be low enough that the base outcome alone carries the return.
