One-line verdict: Nucor's FY2025 screening triggers three failures: accounts receivable outpacing revenue for two consecutive years, free cash flow below 50% of net income for two years, and cash covering only 38% of debt. These are mechanical consequences of a capital-intensive steel company in a margin compression year investing heavily in growth while returning $700M to shareholders via buybacks. Operationally, Nucor remains the strongest steelmaker in the U.S. — CFFO/NI of 1.85, M-Score of -2.49 (clean), and Z-Score of 6.59 (well into safe zone). The F grade reflects screening mechanics rather than genuine financial distress.

America's Steel Giant in a Trough
Nucor is the largest steel producer in the United States, operating through three segments: steel mills, steel products, and raw materials. Per the filing, the company had "approximately 9.4 million tons of annual flat roll steel production capacity" from its Butler, Columbus, and Sinton flat roll divisions, plus "2.0 million tons of flat roll steel processing capacity through The Techs and our Heartland Flat Roll Division."
The 10-K states that "the full reinstatement of the Section 232 steel tariffs without exemptions or exclusions resulted in a lower volume of steel imports compared to 2024. Imports of finished carbon and alloy steel products decreased 17.4% from 2024, supplying approximately 18% of U.S. demand in 2025."
Profitability: Normalizing from the Peak
| Metric | FY2022 | FY2023 | FY2024 | FY2025 | Trend |
|---|---|---|---|---|---|
| Revenue | $41.5B | $34.7B | $30.7B | $32.5B | +5.7% |
| Net Income | $7.6B | $4.5B | $2.0B | $1.7B | Declining |
| Gross Margin | 30.1% | 22.5% | 13.3% | 11.9% | Compressing |
| Net Margin | 18.3% | 13.0% | 6.6% | 5.4% | Thinning |
| ROE | 41.3% | 21.6% | 10.0% | 8.3% | Declining |
Gross margin has compressed from 30.1% in FY2022 to 11.9% in FY2025. Per the filing, the key driver is "changes in metal margins, which is the difference between the selling price of steel and the cost of scrap and scrap substitutes." The filing explains that "increases or decreases in the cost of scrap and scrap substitutes that are not offset by changes in the selling price of steel can quickly compress or expand our gross margins."
Revenue grew 5.7% — modest but positive. The steel mills segment accounted for 72% of consolidated net sales, up from 69% in FY2024, reflecting Nucor's growing sheet steel volumes (10.0 million tons shipped in FY2025 vs. 9.5 million in FY2024).
Cash Flow: CapEx Consuming the Harvest
| Metric | FY2023 | FY2024 | FY2025 |
|---|---|---|---|
| Operating Cash Flow | $7.1B | $4.0B | $3.2B |
| Net Income | $4.5B | $2.0B | $1.7B |
| CFFO / NI | 1.57 | 1.96 | 1.85 |
| CapEx | $2.2B | $3.2B | $3.4B |
| Free Cash Flow | $4.9B | $0.8B | -$0.2B |
Per the filing: "capital expenditures totaled approximately $9.73 billion over the last three years, with approximately 91% going to capital expenditures and the remainder going to acquisitions." This massive investment program has consumed free cash flow. Nucor's capital allocation strategy is explicit: "Investing in our business for profitable long-term growth through our multi-pronged strategy of optimizing existing operations, greenfield expansions and acquisitions. Returning capital to our stockholders through cash dividends and share repurchases."
CFFO/NI of 1.85 remains robust — profits are genuine and backed by cash. The problem isn't earnings quality; it's the pace of capital deployment. "The Company repurchased $700 million of its common stock in 2025 ($2.22 billion in 2024 and $1.55 billion in 2023)."
The 18-Point Screening
Revenue Quality
| # | Check | Result | Detail |
|---|---|---|---|
| A1 | DSO Change | :white_check_mark: | DSO 35 days, +3 days YoY |
| A2 | AR vs Revenue Growth | :x: | AR outpaced revenue for 2 consecutive years |
| A3 | Revenue vs CFFO | :white_check_mark: | Revenue +5.7%, CFFO -18.7% |
A2 red flag. AR growth exceeded revenue growth for two consecutive years. In a steel company, this can reflect changing customer mix (more distributor sales with longer payment terms) or end-of-year shipment timing. Nucor's DSO only increased 3 days to 35, which remains low for a heavy industrial company. This flag is worth monitoring but less concerning than in a software or services company.
Expense Quality
| # | Check | Result | Detail |
|---|---|---|---|
| B1 | Inventory vs COGS | :white_check_mark: | Inventory +7.0% vs COGS +7.4% |
| B2 | CapEx vs Revenue | :white_check_mark: | CapEx +7.8% vs revenue +5.7% |
| B3 | SG&A Ratio | :white_check_mark: | SG&A/Gross Profit = 31.4% |
| B4 | Gross Margin | :white_check_mark: | 11.9%, -1.4pp, stable |
Expense quality is clean. Inventory and COGS are moving in lockstep.
Cash Flow Quality
| # | Check | Result | Detail |
|---|---|---|---|
| C1 | CFFO vs Net Income | :white_check_mark: | CFFO/NI = 1.85, profits backed by cash |
| C2 | Free Cash Flow | :x: | FCF below 50% of NI for 2 years |
| C3 | Accruals Ratio | :white_check_mark: | -4.2%, low accruals |
| C4 | Cash vs Debt | :x: | Cash $2.7B covers only 38% of debt $7.1B |
C2 and C4 are failures. FCF was negative in FY2025 (-$188M) and barely positive in FY2024 ($806M), driven by the massive CapEx program. Debt rose from $6.8B (FY2023) to $7.1B (FY2025). Per the filing, approximately 24% of long-term debt carries variable interest rates.
However, the Z-Score of 6.59 — nearly twice the safe threshold of 3.0 — shows this isn't distress. Nucor's retained earnings base ($0.90 of every dollar of assets funded by retained earnings historically) provides massive equity cushion.
Balance Sheet
| # | Check | Result | Detail |
|---|---|---|---|
| D1 | Goodwill + Intangibles | :warning: | $7.2B = 34% of equity |
| D2 | Leverage | :white_check_mark: | Debt/EBITDA = 1.7x, healthy |
| D3 | Soft Asset Growth | :white_check_mark: | Other assets +7.0% vs revenue +5.7% |
| D4 | Asset Impairment | :white_check_mark: | Write-offs normal |
D1 watch. Goodwill of $4.3B and intangibles of $2.9B total $7.2B, or 34% of equity. Per the filing, "our fourth quarter 2025 annual goodwill impairment analysis did not result in an impairment charge. Management does not believe that future impairment of these reporting units is probable." However, the filing warns that "an increase of approximately 50 basis points in the discount rate, a critical assumption in which a minor change can have a significant impact."
Acquisition Risk
| # | Check | Result | Detail |
|---|---|---|---|
| E1 | Serial Acquirer FCF | :white_check_mark: | FCF after acquisitions positive |
| E2 | Goodwill Surge | :white_check_mark: | Goodwill -3% YoY |
Manipulation Score
| # | Check | Result | Detail |
|---|---|---|---|
| F1 | Beneish M-Score | :white_check_mark: | -2.49 (clean, but narrow) |
M-Score of -2.49 passes the -2.22 threshold with less cushion than ideal. The DSRI (1.098) and GMI (1.118) components are slightly elevated, reflecting the AR growth and margin compression. Not alarming, but tighter than most.
Key Risks from the 10-K
1. Tariff Policy Is a Double-Edged Sword
Per the filing, Section 232 tariffs reduced imports to "approximately 18% of U.S. demand in 2025." This benefits Nucor competitively. But the filing also warns that "many of these non-U.S.-based competitors operate in non-market economies and are often state subsidized or state owned." Any relaxation of trade policy would immediately expose Nucor to lower-cost imports.
2. Metal Margin Compression
Gross margins have halved from 30.1% to 11.9% over three years. The filing explicitly names the risk: "changes in metal margins" are the "key driver of our profitability." Scrap prices are the largest input cost, and Nucor has limited control over them.
3. Massive CapEx Program With Uncertain Returns
$9.73 billion in capital expenditures over three years — funded partly by debt — is a bet that expanded capacity will generate returns when the cycle turns. Per the filing: "we believe that these investments will help us deliver higher returns on invested capital and long-term growth. Further, we believe shifting our product mix to a greater proportion of value-added products will make our overall business less volatile."
4. Goodwill Sensitivity to Discount Rates
Management acknowledged that a 50 basis point increase in the discount rate could have "a significant impact" on goodwill valuations. With $4.3B in goodwill and a declining-margin environment, this is a latent risk.
Summary
Grade: F. Three mechanical failures driven by a capital-intensive growth phase during a margin trough.
Nucor is operationally strong: CFFO/NI of 1.85, accruals near zero, Z-Score of 6.59, and the U.S. steel market is protected by tariffs. The F grade reflects the combination of two consecutive years of AR outpacing revenue, CapEx-driven negative FCF, and cash covering only 38% of debt. These are symptoms of an aggressive capital deployment strategy during a cyclical trough, not of financial distress or manipulation.
The critical question is whether Nucor's $9.7B three-year CapEx program will generate adequate returns when margins recover. If margins rebound to even 20%, this looks visionary. If 12% margins persist, the company will continue burning free cash flow.
