On Tuesday, December 31, 2025, QXO Inc (NYSE: QXO) shares plunged 8.3% after William Blair analyst Ryan Merkel lowered the company’s EBITDA forecasts for both the fourth quarter of 2025 and the first quarter of 2026. The cuts stem from a proprietary survey revealing a downturn in roofing volumes, exacerbated by unfavorable weather, which pressured investor sentiment and cast doubt on near-term earnings.

William Blair Slashes Q4 and Q1 EBITDA Estimates on Roofing Survey Weakness

William Blair adjusted its Q4 EBITDA forecast to $152 million, well beneath the Street consensus of $203 million. Meanwhile, the first-quarter EBITDA projection was trimmed to $130 million, short of analysts’ expected $167 million. These revisions followed data from a proprietary survey of major roofing distributors showing a 10% year-over-year decline in fourth-quarter roofing volumes. Residential volumes dropped between 10% and 11%, despite prices rising roughly 1%. Nonresidential volumes declined by a mid-single-digit percentage, along with slightly lower prices.

Merkel highlighted that the final months of 2025 faced multiple headwinds. Weak new housing starts, a lack of storms, poor weather in December, and tough year-over-year storm comparisons particularly affected October sales. The holiday season and unfavorable December weather further dampened demand, contributing to softer volumes and lower revenue expectations.

Strategic Focus on M&A amid Near-Term Challenges

While the current volume and earnings outlook is subdued, William Blair emphasizes QXO’s planned mergers and acquisitions as a key growth vector. The company targets larger deals spanning multiple verticals, pursuing acquisition multiples ranging from 8 to 14 times EBITDA. Such strategic initiatives support QXO’s ambitious goal of reaching $50 billion in revenues.

Looking forward to 2026, industry contacts anticipate roofing volumes to remain flat initially. Meaningful volume recovery is expected to align with the start of storm season in March or April. Until then, the roofing sector is likely to experience constrained demand, reflected in QXO’s cautious near-term outlook.

QXO Stock: Market Outlook

QXO’s 8.3% stock decline on December 31 follows William Blair’s sharp cut to quarterly EBITDA estimates, anchored in softer roofing market fundamentals and unfavorable weather conditions. Despite these near-term pressures, the company’s emphasis on transformational M&A offers a potential catalyst that investors will monitor closely in 2026. The timing and execution of these acquisitions, alongside the seasonal rebound in roofing volumes, will be critical in shaping QXO’s performance going forward.
