Nucor Lowers Q3 Guidance Amid Raw‑Material Cost Pressures, Shares Slip

Nucor Corporation (NYSE: NUE) recently issued guidance for the third quarter of 2026, projecting diluted earnings per share in a range of $5.55 to $5.65. That figure came in well below Wall Street’s consensus estimate of approximately $5.89 per share (“guidance of $5.55–$5.65 per share,” “below Wall Street’s $5.89 consensus”) according to financial reports from PR Newswire and BestStocks .

Following the guidance update, Nucor’s stock responded sharply, falling around 6.3% in value as investors digested the outlook (“pulled back 6.32% … following Q3 2026 earnings guidance of $5.55–$5.65 per share … valuation 2026‑09‑18‑6.3%”) according to BestStocks. An additional intraday decline of approximately 2.1% occurred as the company’s comments on the headwinds—particularly raw-material costs and lack of one-time benefits—spurred further sentiment pressure (“extended losses … stock fell 2.08% intraday … following a 6.4% drop previously reported”) from the same source.

Raw-Material Costs & Absent One-Time Gains Tighten Margins

Management emphasized that margins will be squeezed in Q3 as several one-time factors that boosted earnings in Q2—such as a $130 million cash refund linked to raw-material procurement and a $61 million non-cash pre-tax gain from an investment in Helion—will no longer recur (“absence of one-time tailwinds ($130M cash refund and $61M Helion gain in Q2) and sector‑wide margin pressure”) as per BestStocks. Compounded by rising costs for raw materials, the company acknowledged this cost pressure would weigh on its earnings trajectory.

Operational Strength Provides Context Amid Guidance Miss

Despite the softer outlook, underlying operational metrics remain solid. In the second quarter, Nucor delivered record steel mill shipments of 7.1 million tons—marking a consecutive quarterly high—and generated free cash flow of $829 million, the strongest since 2023 (“record steel mill shipments of 7.1 million tons … free cash flow reached $829M”) as outlined by Investing.com summaries of Nucor’s call. Management maintained full-year capital expenditure guidance around $2.5 billion and affirmed that expansion projects—including a West Virginia sheet mill scheduled to begin ramping in early 2027—are on track (“West Virginia sheet mill on track for early 2027 ramp; capex guidance maintained at $2.5B for 2026”) from the same source.

Looking Ahead: Focus on Demand, Cost Management

Management offered optimism for demand trends through the rest of 2026, citing growth across infrastructure, energy, manufacturing, reshoring, and data-center sectors (“management cited trade enforcement and demand from energy, data centers, and reshoring as key growth drivers”) according to Investing.com. The company expects Q3 earnings to benefit from improved pricing in steel mills and stronger performance in steel products, even though margin pressures persist (“Q3 earnings to improve in Steel Mills and Steel Products segments”) from Investing.com.

Going forward, investors will keenly watch whether elevated raw-material costs ease or whether Nucor can offset these pressures through pricing and volume. The company’s ability to execute on its growth projects and maintain cash generation could help stabilize sentiment despite the guidance miss.
