Auditor: Ernst & Young LLP (PCAOB ID 42) — Unqualified opinion (critical audit matters identified)
One-line verdict: Steel Dynamics posted $18.2 billion in net sales and $1.2 billion in net income, but the screening triggers two failures: free cash flow below 50% of net income for two consecutive years (driven by a massive aluminum expansion CapEx program), and cash of $770M covering only 18% of $4.2 billion in total debt. The company shipped 10.0 million tons of sheet steel (up from 9.5M), is building its first aluminum flat-rolled products facility, and authorized $1.5 billion in new share repurchases. The M-Score of -2.40 barely clears the manipulation threshold with a DSRI of 1.146 — AR grew 18.7% on 3.6% revenue growth. This is a capex-heavy growth phase for a fundamentally strong steel company.

The Aluminum Bet
STLD is primarily a domestic electric arc furnace (EAF) steelmaker operating through three segments: Steel Operations (72% of FY2025 net sales), Steel Fabrication, and Raw Materials. Per the filing, the company had "approximately 9.4 million tons of annual flat roll steel production capacity" and shipped 10.0 million tons of sheet steel in FY2025.
The transformative strategic initiative is aluminum: the filing references "Unity Aluminum Inc." within the aluminum operations. STLD is building a new aluminum flat-rolled products facility that is consuming significant capital. Additionally, "Steel Dynamics Inc. Biocarbon Solutions" within steel operations suggests investment in alternative feedstocks.
Per the filing, "our steel operations accounted for 72%, 69%, and 67% of our consolidated net sales during 2025, 2024, and 2023, respectively." The rising concentration suggests the steel products and raw materials segments are growing more slowly.
Profitability: Post-Peak Normalization
| Metric | FY2022 | FY2023 | FY2024 | FY2025 | Trend |
|---|---|---|---|---|---|
| Revenue | $22.3B | $18.8B | $17.5B | $18.2B | +3.6% |
| Net Income | $3.9B | $2.5B | $1.5B | $1.2B | Declining |
| Gross Margin | 27.5% | 21.5% | 16.0% | 13.2% | Compressing |
| Net Margin | 17.4% | 13.0% | 8.8% | 6.5% | Thinning |
| ROE | 47.5% | 27.6% | 17.2% | 13.2% | Normalizing |
Revenue grew 3.6% but margins continued their multi-year compression from the FY2022 steel super-cycle peak. Gross margin of 13.2% is down 14.3 percentage points from the FY2022 peak. Net income of $1.2B is less than a third of the $3.9B earned in FY2022.
Per the filing, sheet steel production from "Butler, Columbus, and Sinton" divisions totaled 8.1 million tons shipped (up from 7.7M), while "Flat Roll divisions Steel Processing divisions" added 2.1 million tons.
In February 2025, STLD's "board of directors authorized a share repurchase program of up to $1.5 billion of our common stock."
Cash Flow: CapEx-Heavy Growth Phase
| Metric | FY2023 | FY2024 | FY2025 |
|---|---|---|---|
| Operating Cash Flow | $3.5B | $1.8B | $1.4B |
| Net Income | $2.5B | $1.5B | $1.2B |
| CFFO / NI | 1.44 | 1.20 | 1.22 |
| CapEx | $1.7B | $1.9B | $948M |
| Free Cash Flow | $1.9B | -$24M | $502M |
CFFO/NI of 1.22 confirms profits are cash-backed. The problem is CapEx: $1.9B in FY2024 (which produced negative FCF) and $948M in FY2025. The filing explains that the company's "total long-term debt to capitalization ratio was 32.1% and 26.5% at December 31, 2025, and December 31, 2024, respectively" — debt increased to fund the aluminum expansion and the NPS acquisition (December 1, 2025).
The company's revolving credit facility provides "$1.2 billion Revolver" maturing July 2028, giving STLD ample liquidity beyond its cash position.
The 18-Point Screening
Revenue Quality
| # | Check | Result | Detail |
|---|---|---|---|
| A1 | DSO Change | :white_check_mark: | DSO 34 days, +4 days YoY |
| A2 | AR vs Revenue Growth | :warning: | AR +18.7% vs revenue +3.6% |
| A3 | Revenue vs CFFO | :white_check_mark: | Revenue +3.6%, CFFO -21.4% |
A2 watch. AR surged 18.7% on 3.6% revenue growth. DSO increased 4 days to 34. The December 1, 2025 acquisition of New Process Steel (NPS) likely added receivables to the year-end balance with virtually no revenue contribution. This is acquisition timing noise.
Expense Quality
| # | Check | Result | Detail |
|---|---|---|---|
| B1 | Inventory vs COGS | :white_check_mark: | Inventory +20.1% vs COGS +7.1% |
| B2 | CapEx vs Revenue | :white_check_mark: | CapEx -49.2% vs revenue +3.6% |
| B3 | SG&A Ratio | :white_check_mark: | SG&A/Gross Profit = 32.0% |
| B4 | Gross Margin | :white_check_mark: | 13.2%, -2.8pp, manageable |
CapEx dropped 49% as the Sinton flat-roll mill moved from construction to production phase. Inventory rose 20% while COGS rose only 7% — borderline but not flagged given steel is a seasonal business with strategic stockpiling.
Cash Flow Quality
| # | Check | Result | Detail |
|---|---|---|---|
| C1 | CFFO vs Net Income | :white_check_mark: | CFFO/NI = 1.22, profits backed by cash |
| C2 | Free Cash Flow | :x: | FCF below 50% of NI for 2 years |
| C3 | Accruals Ratio | :white_check_mark: | -1.6%, low accruals |
| C4 | Cash vs Debt | :x: | Cash $770M covers only 18% of debt $4.2B |
C2 failure. Two consecutive years of FCF below 50% of net income reflects the enormous CapEx program. FY2024 FCF was actually negative (-$24M) while FY2025 recovered to $502M as CapEx moderated. If CapEx continues declining, this flag should clear in FY2026.
C4 failure. Total debt rose from $3.2B (FY2024) to $4.2B, with long-term debt jumping from $2.8B to $4.2B. The debt increase financed the aluminum expansion and NPS acquisition. Cash of $770M provides only 18% coverage, but the $1.2B revolving facility provides substantial backup.
Balance Sheet
| # | Check | Result | Detail |
|---|---|---|---|
| D1 | Goodwill + Intangibles | :white_check_mark: | $0.8B = 9% of equity |
| D2 | Leverage | :white_check_mark: | Debt/EBITDA = 2.0x, healthy |
| D3 | Soft Asset Growth | :white_check_mark: | Other assets -18.2% vs revenue +3.6% |
| D4 | Asset Impairment | — | No write-off data available |
The balance sheet is clean beyond the debt level. Goodwill is minimal at $477M, leverage at 2.0x is healthy, and the Z-Score of 6.75 is among the highest in this batch. Total assets of $16.4B against $7.5B in liabilities gives the company a substantial equity cushion of $8.9B.

Manipulation Score
| # | Check | Result | Detail |
|---|---|---|---|
| F1 | Beneish M-Score | :white_check_mark: | -2.40 (clean, very narrow) |
M-Score of -2.40 passes with only 0.18 points of cushion — the narrowest margin in this batch. DSRI at 1.146, GMI at 1.214, and SGAI at 1.112 are all modestly elevated, reflecting the combination of AR growth, margin compression, and rising SG&A. No single component is alarming, but the aggregate proximity to the threshold bears watching.
Key Risks from the 10-K
1. Aluminum Expansion — New Territory
STLD is a steelmaker entering the aluminum market for the first time. The filing references "Unity Aluminum Inc." The aluminum flat-rolled products market has different competitive dynamics, customer relationships, and cost structures than steel. This is a significant strategic bet that could either diversify the business or dilute returns.
2. Steel Price Cyclicality
Gross margin has compressed from 27.5% to 13.2% over three years. The filing warns of "significant price and other forms of competition from other steel and aluminum producers, scrap processors and alternative materials." Steel pricing is inherently cyclical, and STLD has limited ability to control selling prices.
3. Environmental and Emissions Regulations
The filing warns of "increased environmental, greenhouse gas emissions and sustainability considerations from our customers and investors or related regulations." As an EAF steelmaker, STLD has lower emissions than blast furnace competitors, but regulatory costs are rising. The filing notes that "environmental capital expenditures and costs for environmental compliance may increase in the future."
4. Debt Increase During Margin Compression
Long-term debt rose 49% from $2.8B to $4.2B while margins compressed. If steel prices decline further, the combination of higher debt service and lower earnings could pressure cash flow.
Summary
Grade: F. Two failures driven by aluminum expansion CapEx and acquisition-funded debt.
Steel Dynamics is operationally healthy: CFFO/NI of 1.22, accruals near zero, Z-Score of 6.75, minimal goodwill, and 2.0x leverage. The F grade reflects the CapEx-heavy growth phase (consuming FCF for two years) and the debt increase from $3.2B to $4.2B. The M-Score of -2.40 is the narrowest pass in this batch but remains clean.
The strategic question is whether STLD's aluminum bet pays off. If it does, the company emerges as a diversified metals producer with less cyclical earnings. If it doesn't, STLD will have consumed significant capital during a margin trough for a business it has no experience operating.
