Nucor (NYSE: NUE) falls 6% as Q3 guidance misses despite steel earnings rebound

Nucor Corporation (NYSE: NUE) fell 6.3% to $248.38 on September 18 after forecasting third-quarter earnings of approximately $5.55 to $5.65 per diluted share, below the roughly $5.87 Wall Street consensus. The selloff came even though the midpoint of guidance, $5.60, would represent more than double the $2.63 per share Nucor earned in the third quarter of 2025.

That contradiction makes the stock particularly interesting. Nucor is not warning that the steel cycle has collapsed. It expects stronger sequential earnings from steel mills and steel products, but weaker raw-material profitability and the absence of a prior-quarter procurement refund mean consolidated earnings are not rising as rapidly as investors had expected.

Why did Nucor fall when Q3 earnings are still expected to be very strong?

Expectations matter more than year-over-year comparisons. Analysts were already modelling a substantial earnings recovery because US steel pricing strengthened sharply during 2026.

Nucor’s $5.55 to $5.65 guidance therefore needed to be judged against a consensus around $5.87 rather than last year’s $2.63. The $5.60 midpoint sits about 4.6% below that consensus estimate, enough to trigger a meaningful reset after the stock had rallied strongly.

The shares entered September 18 at $265.14 and had traded as high as roughly $280 during the preceding year. Even after closing at $248.38, Nucor remained dramatically above its 52-week low around $131.

A stock that has nearly doubled from its low needs increasingly strong earnings surprises to keep rerating. Merely producing much higher profit than last year can disappoint when investors have already anticipated the rebound.

What changed between Nucor’s Q2 and Q3 earnings?

Nucor reported second-quarter net earnings of $1.16 billion, or $5.04 per diluted share, and adjusted earnings of $4.84. Net sales reached $10.40 billion and EBITDA was approximately $2.02 billion.

The quarter also included approximately $130 million of cash refunds associated with prior-period raw-material procurement costs, helping steel-mill profitability. That benefit does not repeat in Q3.

For the September guidance, Nucor expects improved earnings in steel mills as higher realised prices offset stable volumes and expects steel-products earnings to strengthen with better pricing and volumes. Raw materials are expected to weaken because of lower pricing and shipments.

The quality of earnings is therefore shifting. Core steel-making profitability appears healthy, but some favourable Q2 items are rolling off while raw-material economics deteriorate.

Investors need to distinguish between a temporary quarterly comparison issue and an early signal that the steel-price cycle itself has peaked.

Are high US steel prices helping Nucor or creating a dangerous expectations bubble?

US steel benchmark prices have risen sharply during 2026, supported by trade protection, reduced import competition and reasonably firm demand. Investors consequently pushed Nucor and several peers substantially higher before the September guidance reset.

Higher steel prices improve realised revenue per ton, but steelmakers do not keep every dollar of price increase. Scrap, energy, labour and raw-material costs also move, while contract prices can reset with a lag.

High prices can additionally encourage customers to delay purchases if they expect eventual normalisation. Construction and manufacturing demand therefore matter just as much as spot steel benchmarks when assessing how long the cycle can last.

Nucor’s diversified model provides some protection because it operates both steel mills and downstream steel-products businesses. Fabricated products can capture additional margin beyond basic steel production when construction markets are healthy.

The current guidance indicates that those core businesses remain strong enough to produce much higher earnings than a year ago. The market’s concern is about the incremental direction rather than the absolute profitability level.

Does the 6% selloff make Nucor inexpensive after its huge rally?

At $248.38, Nucor is about 11% below its 52-week high around $280 but roughly 89% above the low near $131. This is therefore a correction inside a major rerating, not a distressed valuation setup.

Using the $5.60 Q3 guidance midpoint as though it represented a steady quarterly run rate would imply more than $22 of annualised earnings, but steel cycles are too volatile for that simplistic calculation to be reliable.

The better question is what “normalised” earnings look like if steel prices retreat from current levels. Investors buying cyclical stocks near strong commodity pricing environments can be misled by low-looking price-to-earnings multiples because the denominator may represent peak-cycle profit.

Nucor’s advantage is its financial strength and long capital-return history. The company entered 2026 with strong credit ratings and authorised a new $4 billion repurchase programme, giving it flexibility through the cycle.

That does not eliminate cyclicality, but it can make downturns easier to navigate than for highly leveraged competitors.

What should Nucor investors watch after the guidance miss?

The first issue is realised steel pricing. If steel-mill prices remain strong into the fourth quarter, Q3’s consensus miss may look more like an expectations reset than the beginning of an earnings downturn.

Raw-material margins are the second variable. Nucor specifically expects weaker performance there, so scrap prices, direct-reduced-iron economics and internal procurement costs deserve attention.

Third, investors should monitor capital returns. A falling stock price alongside strong cash generation can make repurchases more accretive, but only if management believes the equity is attractively valued relative to future-cycle earnings.

The September 18 decline does not tell investors that Nucor’s business is deteriorating sharply. It tells them expectations had become extremely demanding. After a year in which steel prices and the stock both surged, a guidance midpoint more than twice last year’s earnings was somehow not enough.
