Nucor guided third-quarter earnings to $5.55 to $5.65 per diluted share in a release dated September 17, and the midpoint of that range, $5.60, sits about 5 percent below the $5.89 consensus tracked by LSEG and reported by TIKR. The shares closed Friday, September 18 at $248, down 6.4 percent, repricing the stock for the disappearance of two one-off gains rather than for any signal of weaker steel demand.
The range covers the quarter ending October 3, 2026. Nucor reported $5.04 per diluted share in the second quarter of 2026, or $4.84 on an adjusted basis, and $2.63 in the third quarter of 2025, so the new guidance still implies earnings up about 11 percent sequentially and about 113 percent year over year at the midpoint.
What changed inside the guidance
The gap to consensus comes from the base Nucor is comparing itself against. Second-quarter results included $130 million of cash refunds tied to raw material procurement costs from prior periods, booked in the steel mills segment, and the company says it does not expect a similar benefit in the third quarter. They also included a $61 million non-cash, pre-tax gain from a higher valuation of its stake in Helion, a fusion energy company, worth $0.20 per diluted share; Nucor defines adjusted net earnings per diluted share as net earnings per diluted share less the per-share impact of that gain, net of tax.
By segment, Nucor expects third-quarter earnings to rise in steel mills and steel products and to fall in raw materials. The steel mills increase is attributed to higher average selling prices and stable volumes, partly offset by higher costs of products sold. Steel products is expected to improve on higher volumes and higher average realized pricing. Raw materials is expected to decline on lower pricing and shipments. Corporate and elimination expense is expected to be higher, reflecting both the absence of the Helion adjustment and intersegment profit eliminations in line with the prior quarter.
Capital returns and the next data point
Nucor repurchased about 2.03 million shares during the third quarter at an average price of $247.04, roughly $501 million at that average, and has returned about $1.36 billion to shareholders through buybacks and dividends so far this year. Full results are due after the close on October 26, with a conference call the following morning.
The read-across from Steel Dynamics
Nucor was not alone in guiding below the Street. Steel Dynamics, which issued its guidance the same day, put third-quarter earnings at $5.34 to $5.38 per diluted share, against a consensus of $5.66 as tracked by MarketBeat, and against its own $3.69 in the second quarter of 2026 and $2.74 in the third quarter of 2025. Its commentary points in the same direction as Nucor's: steel operations profitability expected to be significantly higher than the second quarter on metal margin expansion and record shipments, customer order activity described as strong with a fabrication backlog nearly 50 percent above year-earlier levels and extending into the first quarter of 2027, and lower metals recycling earnings on narrower metal spreads.
Both companies, in other words, are guiding to earnings that grow year over year while undershooting the expectations analysts had built. That distinction matters for how the price reaction should be read.
Why it matters
Nucor's shares had returned about 84 percent over the prior year and 156 percent over five years, according to data compiled by TIKR, and that run left little room for a quarter that merely held steady. TIKR tracks 20 analysts on the stock: eleven rate it buy, three outperform, four hold and one sell, with a mean price target of $285, about 15 percent above Friday's close of $248. TIKR's own mid-case model values the shares at $220 by December 2030. The gap between those two numbers is the point: this guidance reset is being read through valuation rather than through operating fundamentals.
What the guidance does not show
These are company estimates, not audited results, and Nucor quantifies only the earnings range: it gives no volume, pricing or cash-flow figures for the quarter. The segment outlook is directional, and the attribution of the shortfall to non-recurring second-quarter items is the company's own explanation. Consensus figures come from different providers and are not identical across them, so the measured size of the miss depends partly on which estimate is used. The October 26 release, not this guidance, will show whether mill margins actually expanded.
