Steel Dynamics (STLD) Stock: Why It Fell 5% After Earnings

Quick answer

Steel Dynamics stock fell 4.6% to $233.80 at 8:47am ET on Oct 20, 2026, from a $245.17 close, after its third-quarter results missed on profit. Diluted EPS was $5.26, against a $5.48 consensus. What hurt more is that the company missed its own number: on Sep 17, two weeks before the quarter ended, it guided to $5.34 to $5.38 a share. The shortfall came from its new aluminum mill, where yield losses cut volumes for several weeks. The rest of the report was strong. Revenue of $6.51 billion beat the $6.43 billion consensus, steel shipments hit a record 3.8 million tons, and steel operating income rose 43% from the second quarter to $1.03 billion. The day before, Cleveland-Cliffs jumped 15% on its own results, and Steel Dynamics closed up 1.9%, so the bar going into the report was high.

Our view: Bullish through January 25, 2027, when fourth-quarter results are expected. The case against the stock is real: aluminum fell short of what management said in September, and of the positive second-half aluminum earnings it expected in July, the miss came against a guide set with only two weeks left in the quarter, and the shares already fell 4.1% the day after that guide was published. The case for it carries more weight. The steel segment earned $1.03 billion, more than the whole company's $1.01 billion of operating income, on record volume and higher prices; the aluminum fault has a named cause that the company says it has fixed, with October running well; and at about 11 times forward earnings the premarket drop took about $1.6 billion off the market value for a miss worth about $14 million of profit against the guide midpoint. We would move off Bullish if a fourth-quarter guide shows aluminum still losing money, if the average steel price falls back below the $1,298 a ton of the second quarter, or if fourth-quarter EPS guidance comes in well below the $5.92 analysts expect. This is a view on direction over that window, not a recommendation to trade the stock.

Key takeaways

Steel Dynamics traded at $233.80 at 8:47am ET on Oct 20, down 4.6% from its $245.17 close, after third-quarter diluted EPS of $5.26 missed the $5.48 consensus.
The bigger problem was the company's own guide: on Sep 17, two weeks before the quarter ended, it guided to $5.34 to $5.38 a share. The shortfall came from aluminum, where yield losses cut volumes for several weeks.
The steel business had a record quarter: 3.8 million tons shipped, an average price of $1,400 a ton, up $102, and steel operating income of $1.03 billion, up 43% from the second quarter.
Revenue of $6.51 billion beat the $6.43 billion consensus. The premarket drop took about $1.6 billion off the market value, against a miss of about $14 million of profit from the guide midpoint.
Our view is Bullish through January 25, 2027, when fourth-quarter results are expected: the steel engine is at a record, the aluminum fault is fixed by the company's account, and the shares trade at about 11 times forward earnings.

Oct 20, 2026: an aluminum miss knocks Steel Dynamics 5% before the open

The results came out after the close on Oct 19. The stock traded as low as $222.88 in thin after-hours trading shortly after the release and settled near $232 by early evening. Before the open on Oct 20 it traded at $230.11 at 4:25am and $229.40 at 5am, then firmed to $233.80 by 8:30am and held there at 8:47am, down 4.6%. TIKR put the after-hours drop at about 5.5%.

What pushed it down:

It missed its own guide. The $5.26 compares with the $5.34 to $5.38 range from Sep 17. The Zacks estimate cited by the AP was $5.42, and the consensus was $5.48. When the guide came out in September, Investing.com reported, it was already below a $5.60 consensus.
Aluminum fell short again. The company said volumes "were less than expected over a number of weeks, as yield losses increased at higher operating speeds." In September it had said aluminum earnings would improve meaningfully. The segment lost $26 million, better than the $33 million loss of the second quarter, but not the step up investors had been told to expect.
Mill volumes were light too. Goldman Sachs said lower than expected shipments in aluminum and at the mills "drove the bottom line miss," Investing.com reported. It put the adjusted EBITDA margin at 18.3%, against an 18.9% consensus.
Recycling slipped. Metals recycling earned $33 million, down from $48 million, on lower scrap prices and narrower spreads.

What limited the damage:

The steel quarter was a record. Shipments were 3.78 million tons, the average external selling price was $1,400 a ton, up $102 from the second quarter, and scrap cost per ton melted fell $8 to $404.
The fix is named. The company said the cause "originated from the hot strip mill rolling coolant composition, which has been successfully changed," and that "the mill performance has been excellent in October."
Goldman held its rating. It reiterated Buy with a $299 target, noting that aluminum reached EBITDA breakeven in the quarter.

Peers were mostly flat to lower before the open. At their latest premarket trades, Nucor was down 1.3% at 7:36am, Cleveland-Cliffs was down 2.1% at 8:49am after its 15% gain, and ArcelorMittal was down 0.7%. Steel Dynamics fell more than twice as much as any of them, so most of the move is company news. Our page of today's biggest stock moves covers other names reacting to results.

Going into the session, from the Oct 19 close, RSI(14) stood at 59, the shares sat 2.6% above their 50-day average and 11% above their 200-day average, volume on Oct 19 ran 1.8 times its 20-day average, and the stock was 15% below its 52-week high of $288.74.

The numbers

Measure	Q3 2025	Q2 2026	Q3 2026
Net sales	$4.83B	$6.09B	$6.51B
Operating income	$508M	$700M	$1.01B
Net income	$404M	$534M	$756M
Diluted EPS	$2.74	$3.69	$5.26
Adjusted EBITDA	$664M	$921M	$1.19B
Steel price, per ton	$1,119	$1,298	$1,400

Against the guide and the estimates, the miss looks like this:

Segment operating income tells the same story. Steel rose to $1.03 billion from $721 million. Steel fabrication rose to $91 million from $85 million on 18% higher shipments. Metals recycling fell to $33 million from $48 million. Aluminum lost $26 million, against $33 million in the second quarter. Steel's metal spread, the average price less scrap cost, widened to $996 a ton from $886.

Cash flow was steady. Operating cash flow was $846 million, the company bought back $276 million of stock, about 1% of its shares, and paid $76 million of dividends. Year to date it has repurchased $591 million, the kind of steady return we cover in buybacks as catalysts. Liquidity was $2.4 billion at Sep 30.

The case for the stock

The core business is earning more than it ever has. Steel operating income of $1.03 billion is more than double the $498 million of a year ago, on higher prices and record volume. The fabrication backlog is 50% higher than a year ago and runs into the second quarter of 2027, which gives that business visible work well into next year.

Aluminum is the swing factor, and the company now says the problem is behind it. All three cold mills are running, the first of two CASH lines is operating and is due to ship finished automotive products before year end, and the second is due to run in early 2027. Management said it expects aluminum volumes and profitability to improve in the fourth quarter and through 2027. A segment that went from a $57 million loss a year ago to EBITDA breakeven is moving in the right direction, if more slowly than promised.

The price already reflects a lot of caution. The forward P/E is 10.7, the price-to-sales ratio is 1.5, and the consensus price target is $273, about 17% above the premarket price. For how to read a forward multiple against a trailing one in a cyclical business, see forward P/E versus trailing P/E.

The risks

Credibility on aluminum. In July the company expected positive aluminum earnings in the second half, TIKR noted, and in September it guided to a meaningful improvement. Two slips in a row make the next guide matter more than usual. Our explainer on why guidance changes move stocks covers why the market punishes a missed company guide more than a missed estimate.
Steel prices. The quarter rode a $102 a ton price gain. The company itself noted that more domestic steel and aluminum capacity may enter the market in the coming years.
A high bar for the fourth quarter. Analysts expect $5.92 a share, above this quarter's $5.26, which needs both aluminum and steel prices to hold up.
The cycle. Steel earnings swing with prices and scrap costs, and a multiple of 11 times can rise quickly if earnings fall. See what makes a value trap for the signs of a cheap stock that stays cheap.

Frequently asked questions

Why is Steel Dynamics stock down today?

Steel Dynamics fell about 5% before the open on Oct 20, 2026, after third-quarter diluted EPS of $5.26 came in below the $5.48 consensus and below the $5.34 to $5.38 range the company itself gave on Sep 17. At 8:47am ET the shares were $233.80, down 4.6% from the $245.17 close. The company blamed aluminum volumes, which fell short for several weeks because of yield losses at its new mill.

Did Steel Dynamics beat earnings in the third quarter of 2026?

It beat on revenue and missed on profit. Net sales were $6.51 billion, above the $6.43 billion consensus, and up 35% from $4.83 billion a year earlier. Diluted EPS of $5.26 missed the $5.48 consensus and the $5.42 Zacks estimate cited by the AP, though it was well above the $3.69 of the second quarter and $2.74 a year earlier.

What went wrong at the Steel Dynamics aluminum mill?

The company said aluminum volumes were lower than expected for a number of weeks because yield losses rose at higher operating speeds. It traced the cause to the rolling coolant composition at the hot strip mill, which it has changed, and said mill performance has been excellent in October. The segment lost $26 million, an improvement from $33 million, and reached EBITDA breakeven.

How did Steel Dynamics steel operations do?

They had a record quarter. Steel shipments reached a record 3.8 million tons, the average external selling price rose $102 to $1,400 a ton, scrap cost per ton melted fell $8 to $404, and steel operating income rose 43% from the second quarter to $1.03 billion.

Is Steel Dynamics buying back stock?

Yes. It repurchased $276 million of stock in the third quarter, about 1% of its shares, and $591 million in the first nine months of 2026, about 2%. It also paid $76 million of dividends in the quarter and ended September with $2.4 billion of liquidity.

When does Steel Dynamics report again?

Fourth-quarter results are expected around January 25, 2027, though the company had not confirmed the date as of Oct 20. Before that, it gave third-quarter guidance on Sep 17, and a similar fourth-quarter guide in December would be the first check on whether aluminum recovered.
