Steel Dynamics Q3 2026 Earnings: EPS Up 92% to $5.26 on Record Steel Shipments

Steel Dynamics reported a record third quarter on October 19, 2026: net sales of $6.5 billion (+34.8%), operating income of $1.0 billion (+98.2%), and net income of $756 million, or $5.26 a diluted share — up 92% from $2.74 a year ago. The company shipped a record 3.8 million tons of steel while its average selling price rose $102 a ton sequentially and scrap costs fell $8, a $110-a-ton spread widening that dropped almost straight to the bottom line. This is the mini-mill model working exactly as designed.

The Headline Numbers​

Steel Dynamics' fiscal year is the calendar year, so Q3 2026 is the three months ended September 30, 2026. Every figure below comes from the Form 10-Q and the earnings release, whose condensed statements agree with the 10-Q face statements line for line. Net income throughout this post is attributable to Steel Dynamics shareholders ($756.0 million; consolidated net income was $755.7 million before a $0.3 million loss attributable to noncontrolling interests).

Revenue grew 34.8% while cost of goods sold grew 28.4% ($5,227.1M against $4,070.3M) — that six-point gap on a $6.5 billion base is the entire quarter. Gross profit added $524.4 million on $1,681.2 million of new sales, a 31% incremental margin in a business whose full-year gross margin was 13.2% in 2025. Below gross profit the P&L is clean: SG&A actually fell 6.9% to $187.0 million even as sales grew by a third, and the only cost line that grew faster than revenue is profit sharing (+$38.9 million), which by construction rises with earnings.

The sequential turn is just as sharp. Against Q2 2026, net income rose 41.6% ($534 million to $756 million) and operating income added $306 million, or 44%, on a 6.9% sales gain ($6,091.6M to $6,509.4M). CEO Mark Millett's summary — "steel prices continued to improve and the teams executed well across our steel platform, driving a sequential quarterly increase in consolidated operating income of $306 million, or 44 percent" — attributes the jump to price plus execution, and the segment note confirms it: steel operations alone added roughly $330 million of sequential operating income.

Revenue Deep Dive​

Steel operations did nearly all the work: $870.5 million of the $1,681.2 million sales gain and $534.7 million of the $498.6 million operating-income gain — more than 100% of the profit delta, offsetting a softer fabrication quarter and a wider loss in Other. That concentration is the point of the segment table: this was a steel-spread quarter, not a broad-based one.

Management's demand language is specific enough to check against the ledger. "The domestic steel market remained strong, supported by steady demand, low customer inventories, and historically low import levels," Millett said — and "U.S. steel imports remain well below historical and prior-year levels." The release names the demand leaders as "the energy, non-residential construction, automotive, and industrial sectors." On the supply side: "Steel pricing strengthened, as lead times extended and spot availability tightened across flat-rolled and structural steel products." Every clause has a number behind it: the $102-a-ton sequential price increase, record shipments, and a fabrication backlog "50 percent higher than a year ago and extending into the second quarter 2027." Note what management does not say: there is no "demand exceeds supply" claim anywhere in the release — the wording stays at "steady" and "strong," with the tightness attributed to availability and imports rather than customers clamoring for tons.

Two segments deserve their own paragraphs. Steel fabrication grew sales 23.9% but saw operating income fall 15.4% to $90.6 million — higher steel input costs squeezed the joist-and-deck spread even as shipments rose 18% sequentially. The consolation is the backlog: up 50% year over year, driven by "commercial construction, manufacturing, warehouses, data centers, and healthcare," plus reshoring and infrastructure funding. Fabrication profits tomorrow's steel demand today, and the order book says it is coming.

Aluminum is the growth story: sales nearly quintupled to $493.5 million while the operating loss more than halved to $26.2 million — a 21% sequential improvement — and the platform hit EBITDA breakeven. The release is candid about the imperfection: "Volumes were less than expected over a number of weeks, as yield losses increased at higher operating speeds," caused by hot-strip-mill coolant composition that "has been successfully changed." All three cold mills are now operational, hot-band production reached 91,000 metric tons, and the first CASH line "is expected to ship finished automotive products before the end of the year." Underlying demand "remains strong and is forecast to continue to grow." A startup that is EBITDA-breakeven while still commissioning its finishing lines is ahead of the usual schedule, not behind it.

The Margin Story​

Every margin line sits at or near a three-year high. The mechanics are metal spread, stated in dollars per ton: the average external steel selling price rose $102 sequentially to $1,400 while ferrous scrap cost per ton melted fell $8 to $404. That $110-a-ton widening, times 3.8 million tons, is roughly $418 million of sequential gross-profit tailwind before mix effects — larger than the entire $306 million operating-income gain, meaning volume growth and cost discipline covered everything else that moved against the company.

The pricing detail that matters most is buried one paragraph deeper: "as coated flat rolled steel imports abated due to recent trade actions and demand remained strong, value-added flat-rolled steel spreads also expanded." That sentence names the mechanism twice — trade actions plus steady demand — and it is the reason the margin table looks the way it does. Import competition did not just stay low; in coated flat-rolled it actively retreated during the quarter, letting domestic mills price value-added tons wider. Keep that sentence in mind for the One Big Question.

One line moved the wrong way and deserves honesty: interest expense nearly tripled to $39.3 million from $13.6 million a year ago, even though total debt is roughly flat year over year. The 10-Q gives no single-sentence explanation, but the direction is consistent with less capitalized interest as the aluminum mill build winds down — interest that used to be buried in construction-in-progress now hits the P&L. At 0.6% of sales it is a footnote to this quarter, not a threat to it.

The One Big Question: How Much of This Quarter Is Tariff?​

Steel Dynamics and Cleveland-Cliffs both reported on October 19, both beat on price, and both named the same cause: imports are gone and domestic mills are pricing the gap. Put the two prints side by side and the industry picture — and the company difference — snaps into focus:

Cliffs shipped more tons and earned one-fifth the profit. The gap is the business model: Steel Dynamics' mini-mills run on scrap at a $404-a-ton melt cost with a highly variable cost structure — "our differentiated business model and highly variable cost structure," as the release puts it — while Cliffs carries integrated-mill fixed costs and is still working through the Stelco acquisition. When spreads widen, the low-fixed-cost producer captures more of every dollar. STLD's 19.7% gross margin against Cliffs' 8.3% is that structural advantage expressed in one number.

But both companies' quarters share a single load-bearing assumption: import levels stay "well below historical." Steel Dynamics is unusually explicit that trade policy is doing margin work right now — coated flat-rolled spreads expanded specifically because "imports abated due to recent trade actions." That is a policy tailwind, not a productivity gain, and policy tailwinds can reverse faster than mills can adjust. The bull case is that reshoring, infrastructure spending, and data-center construction keep domestic demand ahead of supply regardless; the release's backlog data (+50% in fabrication, extending into Q2 2027) supports it. The bear case is that $110-a-ton of sequential spread widening included a one-time step-change in the import wall, and next quarter's comparison laps it. The ledger cannot settle that debate — but it tells you exactly how much margin is at stake: every $50 a ton of spread on 3.8 million tons is roughly $190 million of quarterly gross profit, or about 15% of what the company just printed.

Tracking a $6.5 Billion Quarter in Plain Text​

A steel company's earnings release gives you the profit; a double-entry ledger forces every dollar of it to reconcile. Modeling Steel Dynamics in Beancount means the $6,509.4 million of sales, the $5,227.1 million of cost of goods sold, and the $756.0 million attributable profit must sum to exactly zero — with the arithmetic check in a comment no auditor can miss. That discipline is described in how we model every company.

Here is the quarter's income-statement transaction, exactly as pushed (income is negative because it is a credit; expenses are positive debits):

Two modeling choices are worth calling out. First, the filing's own profit-sharing line ($81.3 million, up 92% year over year because it tracks earnings) gets its own account rather than being folded into SG&A — at a company where profit sharing is the compensation philosophy, hiding it would hide the story. Second, the balance sheet carries a curiosity no income statement shows: treasury stock of $8,563.3 million exceeds common stock plus paid-in capital combined, so Equity:CommonStockAndAPIC sits at a $7,319.5 million debit balance — the accumulated footprint of $2.8 billion of buybacks across 2024, 2025, and the first nine months of 2026.

The one balance-sheet number that tells the quarter's narrative is accounts receivable: up 45.5% in nine months ($1,682.7M to $2,446.4M) against 29.4% nine-month sales growth. That is what selling record tons at rising prices looks like — revenue books faster than customers pay. Inventories grew a milder 13.7% to $4,249.1 million, so this is a demand-and-price receivable build, not an overstocking one. Watch the Q4 cash conversion: if receivables normalize, operating cash flow — which grew only 17.0% against 87.3% net-income growth — has a catch-up quarter ahead of it.

The Multi-Year Arc​

The ledger opens at FY2024 — the two most recent audited years plus the current quarter — which is enough to frame the cycle: 2025 was the trough (sales up, margins down, net income off 23%), and 2026 is the snapback. Nine-month operating income of $2,244.9 million already exceeds either full prior year, and nine-month net income of $1,693.5 million is 43% above full-year 2025 with a quarter to go. For context, FY2023 — the last super-cycle year, carried in the 10-K comparatives but outside this ledger's window — printed $18,795.3 million of sales and $2,450.9 million of attributable profit; 2026 is on pace to challenge the sales line while margins rebuild toward it.

The bottom two rows are the compounding story. Steel Dynamics has repurchased $2.7 billion of stock across the ledger's window — 117.3 million shares at the end of FY2024, growing to 126.2 million in treasury by September — shrinking diluted shares 2.7% year over year this quarter alone (147.6M to 143.6M). That is why EPS (+92.0%) outran net income (+87.3%): the denominator keeps falling. Add a dividend raised to $0.53 quarterly and a three-year after-tax ROIC of 13%, and the capital-allocation record is what justifies the premium the market pays for these tons.

The Verdict: Bull vs. Bear​

Bull Case

• Record 3.8M-ton shipments at a $1,400-a-ton average price with scrap at $404: the $996-a-ton metal spread is the widest print in the ledger's window, and it flowed through at a 31% incremental margin.
• Fabrication backlog up 50% year over year into Q2 2027, driven by data centers, reshoring, and infrastructure — contracted visibility no spot-price debate can take away.
• Aluminum hit EBITDA breakeven while still commissioning; 55,000 MT shipped, the first CASH line delivering automotive products before year-end, and sales up 373% year over year.
• Receivables, not inventory, absorbed the working-capital build — a $763.8M nine-month AR increase that converts to cash as customers pay, setting up Q4 operating cash flow.
• $351.7M returned to shareholders in the quarter ($275.6M buybacks + $76.1M dividends) with $2.4B of liquidity and flat total debt: the balance sheet funds both the aluminum ramp and the buyback.

Bear Case

• The release itself attributes coated flat-rolled spread expansion to "recent trade actions" — a policy tailwind that reverses faster than mill costs adjust, and next quarter laps the step-change.
• Interest expense tripled to $39.3M year over year with flat debt, consistent with capitalized interest rolling off as the aluminum build completes — a structural P&L headwind going forward.
• Fabrication operating income fell 15.4% despite 24% sales growth: rising steel costs squeeze the downstream spread, and the segment that profits from tomorrow's demand is earning less today.
• Other-segment operating losses widened to $117.4M from $72.1M, and "Other" is where corporate and growth costs live — the hidden tax on the aluminum expansion.
• Management never says demand exceeds supply — "steady," "strong," "sustained" — while crediting tightness to low imports and inventories; if restocking ends, price follows volume down.

Our Take

This is the best quarter a mini-mill can print in this environment, and the market should pay for quality of earnings, not just quantity: price-led growth, a variable cost structure that converts spreads at 30%+, and a buyback that shrinks the share count every single quarter. The tariff question is real but misframed as a binary — even a partial retreat in import protection leaves Steel Dynamics with record volumes, a fabrication backlog into mid-2027, and an aluminum platform crossing into profitability. The one number to watch is the metal spread: hold $1,400-a-ton pricing into Q4 and the full year challenges the 2023 super-cycle print. This is the company.
