Nucor Fundamental Analysis: NUE Revenue, Margins, Debt and Valuation

US hot-rolled coil pricing has been grinding higher week after week behind a 50% Section 232 tariff wall, and Nucor is the company that posts the number. Its consumer spot price for hot-rolled coil reached $1,240 per short ton in the week of 12 October, a $10/st increase on the week before, after $1,230/st on 5 October and $1,220/st on 28 September. Steel Market Update’s own hot-rolled assessment averaged $1,270/st at 6 October — above Nucor’s posted level — and California Steel Industries, Nucor’s West Coast joint venture, quoted $1,305/st. Lead times have held at three to five weeks.

A Nucor fundamental analysis has to resolve one thing about that run: whether a posted price climbing $20/st over three weeks actually reaches the margin line, or is absorbed by scrap, alloy and energy costs before it gets there. On 19 October the sector supplied a partial answer from the profit-and-loss side. Cleveland-Cliffs reported third-quarter adjusted EBITDA of $612m, against its own prior outlook of approximately $575m and $286m in the second quarter — a $326m sequential improvement it attributed principally to pricing — and guided fourth-quarter adjusted EBITDA to approximately $715m. Flat-rolled price increases are landing. Nucor reports its own third quarter after the close on Monday 26 October, having guided diluted EPS to $5.55–$5.65.

The industry condition

The mechanism behind the price run is supply, not demand. Section 232 duties on steel stand at 50%, raised from 25% in June 2025, and the basis of assessment was overhauled in 2026: a proclamation dated 2 April 2026 moved the duty from a metal-content calculation to the full customs value of the imported product, so goods made entirely or almost entirely of steel — coil among them — now pay 50% on their whole value, with lower rates of 15% or 25% applying to derivative products by content threshold. A further proclamation dated 1 June 2026 adjusted the regime again.

The practical effect is that imported coil is uncompetitive at the margin, domestic mills set the clearing price, and lead times of three to five weeks give them room to post weekly increases without losing volume. Nucor publishes its consumer spot price every Monday, which makes it the visible benchmark for the whole flat-rolled complex — and the reason a Nucor price letter is read as an industry signal rather than a company announcement.

One caution on the numbers, because it is where this series is most often misread. Some outlets quote the same Nucor letter in metric tonnes and others in short tons, which makes identical prices look like different ones. Every figure in this article is per short ton, on Steel Market Update’s series, which matches Nucor’s own per-short-ton posting convention.

A second caution, on recency. A $1,255/st posting for the week of 19 October has been reported in one place but is not corroborated elsewhere. The most recent figure confirmed across independent sources is $1,240/st for the week of 12 October, with $1,230/st on 5 October and $1,220/st on 28 September, and that is the series used here. If Nucor did lift the price again on Monday 19 October, the increase was not corroborated at the time of writing and is not asserted.

What it means for Nucor

Nucor enters this with the flat-rolled price run already visible in its last reported quarter. Second-quarter 2026 net sales were $10.40bn against $8.46bn a year earlier. Net earnings attributable to Nucor were approximately $1.16bn, or $5.04 per diluted share; excluding a non-cash pre-tax benefit of $61m, or $0.20 per diluted share, adjusted net earnings were $1.11bn, or $4.84 per diluted share. The prior-year second quarter produced $603m, or $2.60 per diluted share. That is an earnings line that roughly doubled on higher average selling prices, increased volumes and wider metal margins in the steel mills segment.

Two qualifications belong next to that figure. First, the second quarter included a $130m reduction to cost of products sold from cash refunds relating to prior-period raw-materials procurement costs — a genuine benefit, but not a recurring one, and management has said it does not expect it to repeat. Second, the steel products segment moved the other way, with earnings down year on year as higher steel input costs compressed its margin. Nucor is both a seller and a buyer of its own output, and a rising coil price helps one half of the business at the expense of the other.

For the quarter just ended on 3 October, management guided diluted EPS of $5.55–$5.65 in its 17 September release, with steel mills and steel products both expected to earn more than in the second quarter and raw materials expected to decline. Against second-quarter diluted EPS of $5.04 — or $4.84 adjusted — that guide implies higher earnings while absorbing the absence of the $130m refund, which is a cleaner result than the headline comparison suggests. It is worth noting that the guide landed below the analyst consensus of about $6.20 at the time, and the shares fell on it.

The Openbook read

Momentum. Mixed, and notably unexcited. The shares rose about 1.7% on 19 October, but on light volume — thin participation for a day on which a direct peer reported EBITDA doubling and its own shares rose more than 7%. The pricing momentum in the physical market is far clearer than the momentum in the equity, and that divergence is the honest starting point: the market is not yet treating tariff-supported coil prices as durable earnings.

Growth. Price-led rather than volume-led, which caps how far it can run. Second-quarter net sales of $10.40bn against $8.46bn is 23% growth, and almost all of the earnings expansion came from average selling prices and metal margins rather than from new capacity utilisation. Price-led growth reverses as readily as it arrives. The guided third quarter continues it, but the direction of travel from here depends on a tariff schedule, not on an end-market that is visibly expanding.

Profitability. The factor that matters most here, and the one the Cleveland-Cliffs print helps with. Nucor’s second-quarter diluted EPS of $5.04 reported and $4.84 adjusted shows the gap between the two bases is modest — the $61m pre-tax, $0.20 per share non-cash benefit — which is a cleaner reconciliation than many industrials offer. The pass-through question is answered partly in the affirmative: a peer with heavier flat-rolled exposure beat its own EBITDA outlook by roughly $37m and guided the next quarter $103m higher on pricing. For Nucor, the steel products drag is the offset to watch, because input-cost inflation inside its own downstream business is the clearest mechanism by which a posted price increase fails to reach the consolidated margin.

Solvency. Comfortable, with real net cash capacity. At 4 July 2026 Nucor held $2,478m of cash and equivalents plus $214m of short-term investments, roughly $2,692m in total, against long-term debt and finance lease obligations of $6,389m due after one year, $581m of current portion and $129m of short-term debt — about $7,099m of total debt, or roughly $4,407m net. Set against an earnings line running above $1bn a quarter, that is modest leverage for a capital-intensive cyclical, and first-half repayments of long-term debt were only $37m, so the balance sheet is being held rather than levered.

Reward/Risk. This is where the tariff dependence has to be named plainly. The reward case is straightforward: a price setter in a protected market, posting weekly increases, with a peer having just confirmed the pricing reaches EBITDA, modest net debt, and a third-quarter guide implying higher earnings without a one-off benefit. The risk case is that the protection is policy rather than a competitive moat, and that the market has already registered its doubt — the third-quarter guide came in below consensus. Section 232 has already been restructured twice in 2026, and one proclamation’s adjustments were reported as running through the end of 2027 — a schedule, not a permanence. A 50% duty assessed on full customs value is the single largest input into today’s coil price, and it is the one variable Nucor has no influence over. Investors weighing the flat-rolled complex can compare the factor profiles on the Openbook screener.

The read-across

The condition flows through the listed US steel complex in proportion to flat-rolled exposure. Nucor sits at the front as the price setter and the most diversified of the group, with electric-arc capacity, a large steel products business and raw materials operations that dilute pure coil leverage. Steel Dynamics carries a comparable minimill model with its own downstream fabrication, so it experiences the same two-sided effect of a rising coil price.

Cleveland-Cliffs is the purest read on the condition and the one that has now reported: its third-quarter adjusted EBITDA of $612m against approximately $575m guided, and fourth-quarter guidance of approximately $715m, is the clearest evidence available that flat-rolled pricing is reaching the profit line rather than being absorbed by costs. Management there also pointed to major debt reduction in the fourth quarter and reiterated a target of under 2.5x net debt to EBITDA by the middle of next year, which is what a pricing upcycle does to a levered balance sheet. Commercial Metals sits further from flat-rolled, with long products and rebar exposure driven more by construction activity than by coil.

The honest limit of this read-across is that every name in it is exposed to the same policy variable in the same direction. Diversification within US steel does not diversify tariff risk, and the correlation that looks like sector strength on the way up behaves the same way in reverse.

What to watch next

• Monday 26 October, after the US close: Nucor third-quarter results, with a call at 10:00am Eastern on Tuesday 27 October. The guide is $5.55–$5.65 diluted EPS; the detail that matters is the steel mills metal margin and whether steel products stabilised.
• Nucor’s Monday price letters. The weekly consumer spot price is the highest-frequency read on the condition. A pause or reversal in the $10/st weekly cadence would be the first sign the run is finished.
• Lead times. Three to five weeks is what gives mills pricing power. Compression toward the short end would signal demand, not just supply, has softened.
• Section 232 developments. The regime has been adjusted twice in 2026, in April and June. Any further change to the rate or the assessment basis would move coil prices faster than any company action.
• Cleveland-Cliffs’ approximately $715m fourth-quarter guide. It is now the sector’s stated expectation for what fourth-quarter pricing is worth. Whether peers’ own fourth-quarter commentary corroborates it is the next test of the condition.

The industry condition is well evidenced: tight domestic supply behind a 50% duty, weekly posted increases, three-to-five-week lead times, and a peer confirming the pricing reaches EBITDA. What a Nucor fundamental analysis cannot do is treat that as a structural margin. It is a policy-supported one, and the 26 October print is where the pass-through either shows up in the steel mills metal margin or does not.
