Steel Dynamics posts profit-to-profit expansion on both reporting windows

Bottom line

Across both the three-month reporting period and the six-month year-to-date window, STEEL DYNAMICS INC (ticker STLD) reported a profit on every line item examined, with revenue, operating income, net income attributable to parent, and diluted earnings per share all rising relative to the prior-year comparatives. The filings therefore present a uniform profit-to-profit expansion on both windows, and the consolidated interim statements are the source behind every figure cited below. The reader-facing scope of this section is restricted to the four reported dimensions listed above; cash-flow statement items, balance-sheet line items, share-repurchase amounts, capital expenditure amounts, ordinary-dividend payments, and segment-level detail are not addressed here because this section's purpose is to anchor the headline conclusion and identify the source.

The quarterly comparison covers the three months ended the three months ended June 30, 2026 against the three months ended June 30, 2025. Revenue moved from $4,565,123,000 to $6,091,557,000; operating income moved from $382,855,000 to $700,479,000; net income attributable to parent moved from $298,726,000 to $534,087,000; and diluted earnings per share moved from $2.01 per diluted share to $3.69 per diluted share. Each move is an increase, and each line stayed in profit territory on both sides of the comparison. The year-to-date comparison covers the six months ended June 30, 2026 against the six months ended June 30, 2025. Revenue moved from $8,934,318,000 to $11,296,415,000; operating income moved from $657,999,000 to $1,238,483,000; net income attributable to parent moved from $515,877,000 to $937,523,000; and diluted earnings per share moved from $3.44 per diluted share to $6.47 per diluted share. Each move is again an increase, and each line again remained profitable on both sides of the comparison.

These interim figures are sourced from 10-Q filed for the fiscal period period-ended-2026-06-30, identifier 0001022671, accession 0001104659-26-087414. The source narrative describes STEEL DYNAMICS INC as a leading industrial metals solutions company operating steel-making, metals recycling, steel fabrication, and — more recently — recycled aluminum flat rolled product facilities, organized into four reportable segments. The earnings-per-share computation referenced is described in the cited note covering basic and diluted share counts.

Financial performance

Steel Dynamics Inc.'s interim report under 10-Q for period-ended-2026-06-30 frames its results across steel fabrication, aluminum operations and the joint venture flat rolled mill, with other items capturing the idled Minnesota ironmaking assets and unallocated corporate accounts. The filing period covers the three months ended the three months ended June 30, 2026 and the six months ended the six months ended June 30, 2026, with comparable prior-year windows marked the three months ended June 30, 2025 and the six months ended June 30, 2025.

Revenue from Contract with Customer, Excluding Assessed Tax was $6,091,557,000 USD for the three months ended June 30, 2026 and $11,296,415,000 USD for the six months ended June 30, 2026, compared with $4,565,123,000 USD for the three months ended June 30, 2025 and $8,934,318,000 USD for the six months ended June 30, 2025. On both windows the figure is described as higher than the prior period and moves in the same direction as the authorized year-over-year view.

Operating Income (Loss) was a profit of $700,479,000 USD for the three months ended June 30, 2026 and $1,238,483,000 USD for the six months ended June 30, 2026, against $382,855,000 USD and $657,999,000 USD respectively for the prior-year windows. The transition stays profit to profit on both windows, with the filing reporting a higher result than the prior period.

Net Income (Loss) Attributable to Parent was $534,087,000 USD for the three months ended June 30, 2026 and $937,523,000 USD for the six months ended June 30, 2026, compared with $298,726,000 USD and $515,877,000 USD for the prior-year windows. The transition remains profit to profit, with the current figure reported as higher than the prior period. Earnings Per Share, Diluted was $3.69 per diluted share USD/SHARES for the three months ended June 30, 2026 and $6.47 per diluted share USD/SHARES for the six months ended June 30, 2026, against $2.01 per diluted share USD/SHARES and $3.44 per diluted share USD/SHARES for the prior-year windows, with both transitions staying profit to profit and both windows higher than the prior period.

The filing evidence does not attribute this change to any single cause.

On the accounting context, Note Note 1 describes consolidation of SDI together with its wholly- and majority-owned or controlled subsidiaries, with noncontrolling and redeemable noncontrolling interests reflecting the noncontrolling owners' proportionate share. Use of estimates is flagged, with management indicating the interim statements reflect all normal recurring adjustments necessary for a fair presentation. Inventory accounting under Note Note 4 is stated at lower of cost or net realizable value, while Note Note 6 discusses derivative instruments, with the cited disclosure noting that total gains and losses related to derivatives in fair value hedging relationships, as well as those not designated as hedging instruments, are recognized in costs of goods sold. Note Note 6 also references Level Level 1, Level Level 2 and Level Level 3 fair value hierarchies. Note Note 5 provides a reconciliation of the beginning and ending balances of total equity. Note Note 2 covers a business combination and Note Note 3 covers earnings per share. Recently issued not yet adopted accounting pronouncements reference an ASU on income statement reporting comprehensive income-expense disaggregation disclosures.

Forward guidance and expectations are not stated in numeric form in this section's filing evidence, and no consensus figures are reproduced; readers can broaden their baseline with Broadcom Posts Higher Revenue, Operating Income, and Diluted EPS Year-Over-Year in Filing as a comparable interim window.

Operating drivers and segments

- Steel operations cover the company's electric arc furnace mills across the flat roll, structural and rail, engineered bar and bar divisions, together with coating, processing and warehouse operations and a biocarbon solutions venture. - Metals recycling operations combine Omni ferrous and nonferrous processing, transportation, marketing, brokerage and scrap management services across the United States, Central Mexico and Northern Mexico. - Steel fabrication operations operate through New Millennium Building Systems joist and deck plants in the United States and Northern Mexico, generating revenues from steel joists, joist girders and steel deck systems for non-residential construction. - Aluminum operations comprise a recycled aluminum flat rolled products mill in Columbus, Mississippi, two satellite recycled aluminum slab centers (one in Central Mexico and one planned for Columbus), an ancillary deox-rod facility and a flat rolled mill held as a joint venture in which SDI holds the disclosed equity interest alongside Unity Aluminum, Inc. - Other operations capture subsidiary activity below the reportable thresholds, a joint venture, the idled Minnesota ironmaking operations, and unallocated corporate items such as the senior unsecured credit facility, senior notes, certain other investments and certain profit sharing expenses. - Revenue for the three months ended June 30, 2026 was $6,091,557,000 and for the six months ended June 30, 2026 was $11,296,415,000, compared with $4,565,123,000 for the three months ended June 30, 2025 and $8,934,318,000 for the six months ended June 30, 2025. - Operating Income for the three months ended June 30, 2026 was $700,479,000 and for the six months ended June 30, 2026 was $1,238,483,000, compared with $382,855,000 for the three months ended June 30, 2025 and $657,999,000 for the six months ended June 30, 2025.

- Management frames SDI as a leading industrial metals solutions company with EAF-based steel, metal recycling, downstream fabrication and a newly added aluminum segment that targets the countercyclical sustainable beverage can industry alongside automotive and industrial customers. - The segment mix is described as deliberately diversified across steel, recycling, fabrication and aluminum, with the aluminum flat rolled mill structured as a joint venture with Unity Aluminum, Inc., in which SDI holds the disclosed equity interest. - The recycling segment is positioned geographically across the United States and Central and Northern Mexico, while steel fabrication is anchored in non-residential construction demand. - The filing notes that the company routinely enters into exchange-traded futures to manage price risk tied to nonferrous metal inventory and to purchases and sales of nonferrous (primarily aluminum and copper) and ferrous metals, reducing exposure to commodity related price fluctuations. - Management highlights the addition of aluminum to broaden product offerings into flat rolled products with higher recycled content, signalling a strategic shift away from a purely steel-anchored portfolio.

For the current quarter and six-month year-to-date window, both Revenue and Operating Income moved higher than the prior period on the corresponding year-ago windows, consistent with the authorized profit-to-profit transitions for operating income and the positive-to-positive direction for revenue. The company did not provide a single-line bridge of volume, price, mix or cost in the cited narrative, so a driver-level attribution between the steel, recycling, fabrication, aluminum and other groupings is not available here. The filing evidence does not attribute this change to any single cause. The filing evidence contains no peer or industry comparison. Readers weighing how SDI's segment mix shifts the operating margin profile against industry benchmarks can cross-check the directional pattern against prior coverage such as Broadcom Posts Higher Revenue, Operating Income, and Diluted EPS Year-Over-Year in Filing, though that comparison spans a different industry. The newly issued FASB disaggregation standard referenced in the cited note may sharpen segment-level expense visibility in subsequent filings, but the present evidence does not yet separate steel, recycling, fabrication, aluminum and other operating income contributions.

Cash flow and capital

Steel Dynamics closed the interim period with a cash and equivalents balance of $567,708,000 USD on the balance sheet dated the balance sheet date of June 30, 2026, alongside long-term debt, excluding current maturities, of $4,180,810,000 USD. The accompanying statement of cash flows shows operating activities continuing to be the principal source of liquidity in the three months ended June 30, 2026 and the six months ended June 30, 2026, generating $427,936,000 USD and $576,252,000 USD, respectively, compared with $301,611,000 USD and $454,214,000 USD in the prior-year windows. The authorized comparison notes that operating cash flow moved higher than the prior period on both the three-month and six-month year-to-date bases.

Investing activities were a use of cash in each window, reflecting ongoing property, plant, and equipment outlays. Net cash used in investing totaled -$118,037,000 USD for the three months ended June 30, 2026 and -$257,103,000 USD for the six months ended June 30, 2026, versus -$305,696,000 USD and -$484,455,000 USD in the prior-year comparatives. The authorized comparison describes investing outflows as increasing on both windows. Within that envelope, payments to acquire property, plant, and equipment — the company’s primary growth and maintenance spending line — amounted to $123,842,000 USD in the quarter and $261,821,000 USD for the year-to-date, against $288,331,000 USD and $593,837,000 USD a year earlier. The authorized comparison flags capex as decreasing versus the prior period on both bases, even while the broader investing line moved in the opposite direction. The filing evidence does not attribute this change to any single cause.

Financing activities remained a net use of cash, consistent with an active return-of-capital program. Net financing outflows reached -$298,672,000 USD for the three months ended June 30, 2026 and -$521,431,000 USD for the six months ended June 30, 2026, against -$724,783,000 USD and -$101,488,000 USD in the prior-year comparatives. The authorized comparison characterizes the half-year financing outflow as decreasing versus the prior period while the quarterly financing outflow increased. Within financing, ordinary dividend payments on common stock totaled $76,555,000 USD in the quarter and $149,025,000 USD year-to-date, compared with $74,690,000 USD and $144,204,000 USD a year earlier, with the authorized comparison indicating an increase on both windows. Common stock repurchases — disclosed under Item 2 — absorbed $200,288,000 USD during the quarter and $315,375,000 USD year-to-date, against $200,048,000 USD and $450,186,000 USD in the prior-year windows; the authorized comparison records the quarterly buyback as increasing while the half-year buyback decreased.

Peer and historical context

Steel Dynamics' interim filing reports a clean profit-to-profit improvement on every window we can read off the income statement, and the cash flow statement tells the same story from a different angle.

Revenue from Contract with Customer, Excluding Assessed Tax came in at $6,091,557,000 USD for the three-month reporting period the three months ended June 30, 2026, up from $4,565,123,000 USD in the three months ended June 30, 2025. The six-month year-to-date view was $11,296,415,000 USD versus $8,934,318,000 USD, so the top line is higher on both windows. Operating Income (Loss) moved the same way: $700,479,000 USD against $382,855,000 USD for the quarter, and $1,238,483,000 USD against $657,999,000 USD for the half year. Net Income (Loss) Attributable to Parent followed: $534,087,000 USD for the three months ended June 30, 2026 vs. $298,726,000 USD for the prior-year quarter, and $937,523,000 USD for the six months ended June 30, 2026 vs. $515,877,000 USD for the year-ago half. Operating cash flow tracked higher as well, with Net Cash Provided by (Used in) Operating Activities of $427,936,000 USD for the three months and $576,252,000 USD for the six months, both above the $301,611,000 USD and $454,214,000 USD reported a year earlier. The filings does not break out a peer table, so for cross-issuer context readers can compare with ONEOK Posts Higher Revenue, Operating Income, Net Income and Diluted EPS Year-Over-Year in Interim Filing and Broadcom Posts Higher Revenue, Operating Income, and Diluted EPS Year-Over-Year in Filing, where the same profit-to-profit pattern shows up on similar year-over-year windows.

The filing evidence does not attribute this change to any single cause.

For peers within the metals space we have nothing to lean on here. The filing evidence contains no peer or industry comparison.

The acquisition of the remaining interest in NPS, described in the cited note Note 2, sits on top of this historical baseline. The previously held equity interest was remeasured to an acquisition-date fair value noted in the filing, NPS's operating results have been consolidated since the December effective date, and the related purchase price allocation remains provisional. Because the comparative columns already include the prior-year period without NPS on a fully consolidated basis, the year-over-year gap on revenue and operating income captures both organic change and the inorganic lift from the deal. The filing evidence does not attribute this change to any single cause.

Scenario analysis

At the consensus base case, STEEL DYNAMICS INC (STLD) carries the same profit-to-profit pattern that the latest 10-Q for period-ended-2026-06-30 already discloses on both reporting windows. Reported revenue tracks $6,091,557,000 USD for the three months ended June 30, 2026 against $4,565,123,000 USD for the three months ended June 30, 2025, and $11,296,415,000 USD for the six months ended June 30, 2026 against $8,934,318,000 USD for the six months ended June 30, 2025. Net income attributable to parent is $534,087,000 USD for the three months ended June 30, 2026 versus $298,726,000 USD for the three months ended June 30, 2025, with the six-month picture at $937,523,000 USD for the six months ended June 30, 2026 against $515,877,000 USD for the six months ended June 30, 2025. The filing evidence does not attribute this change to any single cause.

An upside reading is supported by the same filing rather than by external speculation: the year-over-year direction is favorable on both the three-month and six-month windows for revenue and net income. If that directional momentum holds while the newly consolidated NPS contribution matures, the consolidated entity could see compounding benefit given the acquisition's stated focus on value-added manufacturing opportunities, as discussed in Note 2. The provisional measurement-period fair value adjustments tied to that deal — including the Level 3 inputs still being finalized — could also become a source of reported upside if subsequent valuations resolve favorably. For breadth across interim filings with similar profit-to-profit trajectories, the Lizely Finance Earnings Analysis — UFP TECHNOLOGIES INC Interim Filing: Profit-to-Profit Growth on Both Windows and the Lizely Finance Earnings Analysis — ANI Pharmaceuticals Interim Filing: Profit-to-Profit Growth on Both Windows provide neighboring reference points. The filing evidence does not attribute this change to any single cause.

The downside case acknowledges that the filing is light on counter-evidence that would meaningfully size a setback. The provisional fair-value measurement period remains open for the NPS acquisition, with valuations of property, plant, and equipment and certain intangible assets still being obtained; a less favorable resolution would flow through Note 6 once finalized. The Level 2 and Level 3 fair-value tiers referenced in Note 6 also remain exposure points if commodity futures valuations or unobservable inputs move adversely. Inventories stated at the lower of cost or net realizable value, described in Note 4, would likewise be the first place any demand-driven write-down narrative would surface, even though no such write-down is reported here. Counter-evidence specific to the magnitude of any drawdown is not present in the cited notes, and the filing evidence contains no peer or industry comparison. The filing evidence contains no peer or industry comparison. The filing evidence does not attribute this change to any single cause.

Risks and what to watch

The filing presents Steel Dynamics Inc's results under 10-Q period-ended-2026-06-30 for both the three-month reporting period the three months ended June 30, 2026 and the six-month year-to-date period the six months ended June 30, 2026, as filed under accession 0001104659-26-087414 by entity STEEL DYNAMICS INC (CIK 0001022671, ticker STLD). The forward-looking risk register itself sits in Item 1A, the quantitative market-risk discussion in Item 3, and the controls posture in Item 4; the supporting accounting policies referenced here — lower of cost or net realizable value on inventories, the equity roll-forward, the earnings-per-share build, and the fair-value hierarchy across Level 1, Level 2, and Level 3 — appear respectively in Note 4, Note 5, Note 3, and Note 6. Readers should treat those references as the authoritative pointers for any subsequent drill-down.

Counter-evidence worth weighing: revenue moved higher year over year on both windows — $6,091,557,000 USD versus $4,565,123,000 USD for the three months ended June 30, 2026 versus the three months ended June 30, 2025, and $11,296,415,000 USD versus $8,934,318,000 USD for the six months ended June 30, 2026 versus the six months ended June 30, 2025 — yet margin conversion is what ultimately determines whether that top-line growth translates into shareholder value. Net income similarly expanded on both windows — $534,087,000 USD against $298,726,000 USD for the quarter comparison, and $937,523,000 USD against $515,877,000 USD for the six-month comparison — but those reported moves only describe direction, not causation. A revenue gain alongside a proportionally smaller profit gain would imply cost-of-goods or operating-cost pressure, while the opposite pattern would imply operating leverage; the filing, however, does not narrate that breakdown in this view. The filing evidence does not attribute this change to any single cause.

Unknowns and limits of this filing: the document does not provide a granular segment view at this level — The filing evidence does not disclose segment-level detail for this dimension. — so the contribution of steel fabrication, recycled metals, or any downstream arm to the period cannot be isolated from the consolidated lines. No peer set is named here either — The filing evidence contains no peer or industry comparison. — so any read-across to Nucor, Cleveland-Cliffs, or United States Steel is an outside inference rather than a documented comparison. The risk-factor language in Item 1A is referenced but not reproduced in narrative form, so the precise wording of how management frames steel-price volatility, scrap-supply exposure, energy cost, or trade actions is not restated here. Derivative fair-value mechanics under Note 6 point to commodity futures contracts, but the commodity mix and hedge effectiveness are not surfaced in this view.

Metrics to watch next period: the same revenue and net-income lines already grounded here — quarter and half-year revenue, and quarter and half-year net income attributable to parent — are the natural anchors for the next print, since any inflection against the directions flagged above would reset the read. For readers seeking a sense of how a different steel-cycle name framed its own interim period, Broadcom Posts Higher Revenue, Operating Income, and Diluted EPS Year-Over-Year in Filing illustrates a comparable dual-window revenue-and-profit pattern in a non-ferrous context, while ONEOK Posts Higher Revenue, Operating Income, Net Income and Diluted EPS Year-Over-Year in Interim Filing offers a parallel year-over-year dual-window framing in a pipeline operator. Item-by-item drift in Item 1A risk language, the segment disclosure depth in the next interim, and any change in inventory valuation under Note 4 should be monitored alongside the top-line and bottom-line prints.
