Grade: B — One Structural Fail, Otherwise Pristine
Framework: Schilit *Financial Shenanigans* + Beneish M-Score + forensic accounting principles
Data: SEC EDGAR 10-K (Filed February 6, 2026, FY ended December 31, 2025) + Yahoo Finance
Auditor: Deloitte & Touche LLP (PCAOB ID: 34) — Unqualified opinion (1 critical audit matter: Capitalization of properties)
One-line verdict: Union Pacific is an earnings quality machine. Revenue grew 1.1% to $24,510M, net income rose 5.8% to $7,138M (29.1% net margin), EPS increased 8%, and CFFO/NI of 1.30x confirms clean cash-backed earnings. Operating ratio improved to 59.8%. The sole fail — cash of $1.5B covering only 5% of $32.8B debt — is inherent to the railroad industry, where asset-backed infrastructure financing is the norm. Debt/EBITDA of 2.5x and interest coverage of 7.5x demonstrate ample debt service capacity. The Altman Z-Score of 4.6 is safely above the distress threshold. M-Score is unavailable (insufficient data) but the F-Score fraud probability is an extremely low 0.13%.

America's Railroad
Union Pacific operates one of the largest railroad networks in the U.S., with approximately 32,000 route miles across 23 states in the western two-thirds of the country. The railroad hauls freight across multiple commodity groups: grain, coal, industrial products, intermodal containers, and automotive.
From the MD&A: "In 2025, we reported an 8% increase in earnings per share versus 2024. Total volume increased 1% versus 2024, driven by coal, industrial chemicals and plastics, grain and grain products, and rock shipments." Operating metrics improved significantly: "freight car velocity improved 8% and intermodal and manifest Service Performance Index improved 9 and 11 points to 99% and 100%, respectively."
Deloitte's critical audit matter — capitalization of properties — is classic for railroads. UNP capitalizes costs related to track, bridges, and equipment replacement. The distinction between maintenance (expense) and betterment (capitalize) requires significant judgment and directly affects operating ratio.
Financial Performance: Precision Railroading Pays
| Metric | FY2025 | FY2024 | FY2023 | FY2022 |
|---|---|---|---|---|
| Total Revenue | $24,510M | $24,250M | $24,119M | $24,875M |
| Gross Profit | $11,220M | $11,039M | $10,529M | $11,205M |
| Gross Margin | 45.8% | 45.5% | 43.7% | 45.1% |
| Operating Income | $9,846M | $9,713M | $9,082M | $9,917M |
| Net Income | $7,138M | $6,747M | $6,379M | $6,998M |
| EBITDA | $12,940M | $12,461M | $11,891M | $12,589M |
| Interest Expense | $1,309M | $1,269M | $1,340M | $1,271M |
Revenue has been remarkably stable around $24-25B for four years. The story is margin expansion: "Operating revenues grew 1% driven by strong core pricing and higher volume, which more than offset business mix, lower fuel surcharge revenues, and reduced other revenues. Excluding the impact of fuel, our freight revenues grew 3%."
Net margin of 29.1% ($7,138M/$24,510M) is exceptional for any industry. The railroad's regulated monopoly position and precision scheduled railroading (PSR) model produce consistent, predictable earnings.
Cash Flow: Predictable as the Train Schedule
| Metric | FY2025 | FY2024 | FY2023 | FY2022 |
|---|---|---|---|---|
| Operating Cash Flow | $9,290M | $9,346M | $8,379M | $9,362M |
| CapEx | $(3,791)M | $(3,452)M | $(3,606)M | $(3,620)M |
| Free Cash Flow | $5,499M | $5,894M | $4,773M | $5,742M |
| Buybacks | $(2,679)M | $(1,505)M | $(705)M | $(6,282)M |
| Dividends | $(3,236)M | $(3,213)M | $(3,173)M | $(3,159)M |
| D&A | $2,465M | $2,398M | $2,318M | $2,246M |
CFFO/NI of 1.30x demonstrates clean conversion. FCF of $5,499M is massive. Total shareholder returns ($2,679M buybacks + $3,236M dividends = $5,915M) slightly exceed FCF, funded by modest incremental borrowing.
The MD&A notes: "We also invested $3.5 billion in capital to harden our infrastructure, modernize older locomotives, grow our business, improve service, and embed new technologies into our processes." Capital intensity (CapEx/Revenue = 15.5%) is high but expected for a railroad maintaining a 32,000-mile network.
Balance Sheet: Asset-Heavy, Well-Managed
| Item | Dec 31, 2025 | Dec 31, 2024 |
|---|---|---|
| Cash & Equivalents | $1,266M | $1,016M |
| Accounts Receivable | $1,860M | $1,894M |
| Inventories | $787M | $769M |
| Total Current Assets | $4,555M | $4,021M |
| Other Intangible Assets | $745M | $791M |
| Total Assets | $69,698M | $67,715M |
| Total Debt | $32,822M | $32,463M |
| Total Liabilities | $51,231M | $50,825M |
| Stockholders' Equity | $18,467M | $16,890M |
| Retained Earnings | $69,529M | $65,628M |
No goodwill on the balance sheet — Union Pacific was not built by acquisition. The $69.7B of assets are predominantly property, plant, and equipment (track, bridges, rolling stock). Retained earnings of $69.5B reflect over a century of accumulated profits.
Total debt of $32.8B is large in absolute terms but Debt/EBITDA of 2.5x is comfortable. The debt is long-duration, matched against long-lived infrastructure assets. Interest coverage of 7.5x provides ample cushion.

All revenue quality checks pass. AR declining while revenue grows is a positive signal.

| C4 | Cash vs Debt | **FAIL** | Cash $1.5B covers only 5% of debt $32.8B |
C4 context for railroads: Railroads operate capital-intensive, asset-backed businesses with predictable cash flows. The $32.8B debt is secured against $65B+ of physical infrastructure assets with useful lives measured in decades. Debt/EBITDA of 2.5x and 7.5x interest coverage confirm this is not distress — it is efficient capital structure for a regulated infrastructure monopoly.

Key Risks from the 10-K
1. Property Capitalization — Deloitte's Critical Audit Matter
Deloitte flagged the capitalization of properties. Railroads spend billions annually on track maintenance and replacement. The judgment between maintenance expense and capitalized betterment directly affects the operating ratio and reported earnings. Over-capitalization would inflate assets and suppress expenses, overstating earnings.
2. Volume Sensitivity to Economic Cycles
Railroad volumes are a leading indicator of economic activity. "Total volume increased 1% versus 2024" — modest growth. Coal volumes face secular decline from energy transition. Industrial volumes depend on manufacturing activity. A recession would compress both volumes and pricing power.
3. Regulatory and Political Risk
Railroads face Surface Transportation Board regulation on rates and service. Political pressure for rate regulation could constrain pricing power. Environmental regulations on diesel emissions and hazardous materials transport are increasing.
4. Labor Relations
Railroads employ unionized workforces with periodic collective bargaining rounds. The 2022 near-strike (averted by congressional intervention) demonstrated the labor risk. Future labor disputes could disrupt operations and increase costs.
Summary
Grade: B (override from engine F). One structural fail (cash-to-debt 5%) is inherent to railroad capital structure. Zero watch items. All operating metrics are pristine.
Union Pacific is the definition of predictable industrial earnings quality: 29.1% net margin, 1.30x CFFO/NI, -3.1% accruals ratio, zero goodwill, $69.5B retained earnings, 2.5x Debt/EBITDA, 7.5x interest coverage, and an F-Score fraud probability of 0.13%.
The only genuine risk from an earnings quality perspective is the capitalization judgment flagged by Deloitte — the line between maintenance expense and capital improvement determines the operating ratio that drives the entire investment thesis. If capitalization policies were tightened, the operating ratio would rise and reported earnings would decline.
