Auditor: KPMG LLP — Unqualified opinion (1 critical audit matter: sufficiency of audit evidence on capitalization of property expenditures) — auditor since 1982
One-line verdict: Norfolk Southern is a railroad in the middle of being acquired by Union Pacific, with the July 28, 2025 Merger Agreement defining the forward narrative. The accounting is clean by rail standards: DSO of 21 days, CFFO/NI of 1.52, FCF of $2.2B, zero goodwill, and operating ratio improving to 64.2% from 66.4%. Net income of $2.87B is up 10% YoY and up 57% from the 2023 East Palestine trough. But cash of $1.5B covers only 9% of $17.3B in debt — the lowest cash-to-debt ratio of any company in this screen, and a critical fail in our framework. The Eastern Ohio Incident accruals of $474M remain on the balance sheet, and the Ohio Class Action $600M settlement is only half-paid ($315M paid in 2024; $285M remaining). The combined company, if the Union Pacific merger closes, would be America's first transcontinental railroad — but as of Year-End 2025 the STB found the initial application incomplete and a revised application is being prepared.

The Union Pacific Merger — The Defining Event
The MD&A Overview opens: "On July 28, 2025, we entered into a Merger Agreement with Union Pacific, marking a transformational step toward creating America's first transcontinental railroad an outcome we believe will unlock new opportunities for our customers, employees, and the broader U.S. economy."
The Risk Factors dedicate an entire section to "Risks Related to the Mergers," including disclosures that the initial STB application was rejected as incomplete:
"While the initial Merger application with the STB was determined to be incomplete, the Company and Union Pacific are in process of preparing a revised application that incorporates the additional items identified by the STB."
The 10-K also discloses material shareholder litigation:
"Six shareholder derivative complaints were filed in Virginia state court asserting claims for breach of fiduciary duties, waste of corporate assets, and unjust enrichment in connection with safety of the Company s operations… We also entered supplemental disclosure via Form 8-K filed on November 6, 2025, which clarified financial projections, board deliberations, and risk factors related to the Mergers."
Merger-related expenses in 2025 totaled $80M, and the Eastern Ohio Incident created a $190M net operating expense reduction (due to insurance/recoveries exceeding incremental expense).
Financial Performance: Modest Topline, Strong Margin Recovery
From the Consolidated Statements of Income:
| Metric | FY2025 | FY2024 | FY2023 | Trend |

| Railway Operating Ratio | 64.2% | 66.4% | 76.5% | -2.2pp |
Revenue composition per MD&A: Merchandise $7,684M (63%), Intermodal $3,009M (25%), Coal $1,487M (12%). Coal continued declining (-8% YoY) while Automotive grew strongly (+6%) as "growth in automotive and chemicals traffic, reflecting improved service and customer demand, drove merchandise revenues higher." Fuel surcharge revenues fell from $1.2B in 2023 to $828M in 2025, mainly tracking fuel prices.
Eastern Ohio Incident accounting: Note how the "Eastern Ohio incident" line swung from +$1,116M expense in 2023 (the derailment year) to +$325M in 2024 to -$254M recovery in 2025. The 2025 MD&A states: "we also continued to make progress towards resolving environmental and legal matters resulting from the Incident (as defined further and described in Note 19) with insurance and other recoveries during 2025 exceeding incremental expenses."
Adjusted (non-GAAP) net income: Per MD&A reconciliation, adjusted net income was $2,816M in 2025, $2,684M in 2024, and $2,673M in 2023. Adjusted EPS: $12.49, $11.85, $11.74. The GAAP trajectory overstates earnings growth because of the Incident recovery in 2025 and the 2023 Incident charge.
Cash Flow: Strong Conversion
From the Consolidated Statements of Cash Flows:
| Metric | FY2025 | FY2024 | FY2023 |
|---|---|---|---|
| Net Income | $2,873M | $2,622M | $1,827M |
| Depreciation | $1,393M | $1,353M | $1,298M |
| Gains on properties | $(253)M | $(490)M | $(49)M |
| Net Cash from Operating | $4,361M | $4,052M | $3,179M |
| Property Additions | $(2,204)M | $(2,381)M | $(2,327)M |
| Acquisition of CSR assets | — | $(1,643)M | $(22)M |
| **Free Cash Flow** | **$2,157M** | **$1,671M** | **$852M** |
| CFFO/NI | 1.52 | 1.55 | 1.74 |
| Dividends | $(1,215)M | $(1,221)M | $(1,225)M |
| Share Repurchases | $(534)M | — | $(622)M |
CFFO/NI of 1.52 is robust — cash conversion is strong. The 2023 ratio of 1.74 is inflated by the Eastern Ohio Incident being partly a non-cash accrual. FCF excluding the 2024 Cincinnati Southern Railway (CSR) acquisition of $1,643M is the clean comparison: FCF $1,671M in 2024 → $2,157M in 2025 (+29%).
The 2025 cash flow statement includes $253M of gains on property sales (vs $490M in 2024). Per MD&A: "we successfully monetized other properties that resulted in meaningful gains in the current year."
Share repurchases of $534M in 2025 were less than the $622M in 2023 and there were none in 2024 (blackout period around the Ancora proxy contest and merger negotiations).
Balance Sheet: Property-Heavy, Cash-Light
From the Consolidated Balance Sheets:
| Item | FY2025 | FY2024 |
|---|---|---|
| Cash & Equivalents | $1,530M | $1,641M |
| Accounts Receivable, net | $988M | $1,069M |
| Materials and supplies | $271M | $277M |
| Other current assets | $409M | $201M |
| Total Current Assets | $3,198M | $3,188M |
| Investments | $4,089M | $3,370M |
| Properties, net | $36,479M | $35,831M |
| Other assets | $1,470M | $1,293M |
| **Total Assets** | **$45,236M** | **$43,682M** |
| Accounts payable | $1,863M | $1,704M |
| Current maturities LT debt | $607M | $555M |
| Long-term Debt | $16,480M | $16,651M |
| Deferred income taxes | $7,711M | $7,420M |
| Total Liabilities | $29,689M | $29,376M |
| Stockholders' Equity | $15,547M | $14,306M |
Properties of $36.5B dominate the balance sheet — rail lines and locomotives accumulated over 200 years. The depreciation base of $14.6B vs gross $51.1B shows the fleet is moderately depreciated. Railways employ a "group depreciation" model that makes capitalization vs. expense judgment calls significant, which is exactly why KPMG identified property capitalization as the critical audit matter.
No goodwill, no intangibles. Norfolk Southern has grown through organic investment, not M&A. Only the 2024 Cincinnati Southern Railway $1.64B asset purchase is recent, and that was allocated to Properties, not goodwill. D1 passes cleanly.
Cash of $1.5B covers only 9% of $17.3B total debt. This is the lowest cash cushion in our entire screen universe. The MD&A notes that NSC runs with minimal cash because of reliable CFFO of ~$4B/year — but if merger closing is delayed or a second Incident-style event occurs, the cushion is thin. Interest expense of $792M on $17.3B debt implies a blended cost around 4.6%; coverage is 5.5x (EBIT $4,356M / $792M).
Critical Audit Matter: Property Capitalization
KPMG's critical audit matter focuses on how NSC decides whether an expenditure extends an asset's useful life (capitalize) or is routine maintenance (expense):
"We identified the evaluation of the sufficiency of audit evidence related to capitalization of property expenditures as a critical audit matter. Subjective auditor judgment was required in determining procedures and evaluating audit results related to the capitalization of purchased services and compensation due to their usage for both self-constructed assets and repairs and maintenance."
This matters because railroads can materially shift reported earnings by changing the capitalization threshold. NSC capitalized $2.2B of property additions in 2025 against $36.5B of net property — a 6.0% refresh rate. Depreciation was $1.39B, meaning capital additions ran 1.6x depreciation. That gap signals network expansion rather than liquidation, but the capital-vs-expense classification for hundreds of thousands of individual projects is exactly the judgment area KPMG flagged.

Components: DSRI 0.904 (AR days declining), GMI 1.031 (slight gross margin decline), AQI 1.151 (asset quality slight increase), SGI 1.005 (essentially flat revenue), DEPI 0.989, SGAI 1.403, TATA -0.0329 (negative accruals — high quality), LVGI 0.968. The SGAI of 1.403 reflects the compensation increase and merger expenses; not a manipulation signal for a railroad with flat revenue.
Key Risks from the 10-K
1. Union Pacific Merger Risk
From Item 1A — "Risks Related to the Mergers": "The Mergers are subject to conditions, some or all of which may not be satisfied or completed on a timely basis, if at all. Failure to complete the Mergers could have material adverse effects on the Company." Key exposures if the merger fails:
The STB application was initially rejected as incomplete. The risk factors note: "The terms and conditions of the approvals that are granted may impose requirements, concessions, limitations, or costs or place restrictions on the conduct of the combined company s business" and regulators may require divestitures of rail lines.
2. Eastern Ohio Incident Continuing Litigation
From Note 19: "On April 26, 2024, we entered into a class action settlement with the plaintiffs to resolve the Ohio Class Action for $600 million, and we made a partial payment of the settlement in 2024, in the amount of $315 million… Under the class action settlement terms, payment of the remaining balance, including timing, is dependent upon resolution of any further appeals to the settlement."
Further lawsuits remain active: a Pennsylvania school districts class action, Exchange Act and Securities Act shareholder lawsuits (the Exchange Act case survived a motion to dismiss on March 24, 2025 and is now in discovery), and six shareholder derivative matters consolidated July 10, 2025. A DOJ civil complaint was also filed. Incident accruals at $474M at December 31, 2025 remain a balance sheet liability.
3. STB Regulatory Environment
From Item 1 Business: "The STB has jurisdiction to determine whether we are revenue adequate on an annual basis based on the results of the prior year. A railroad is revenue adequate on an annual basis under the applicable law when its return on net investment exceeds the rail industry s composite cost of capital." Revenue adequacy findings can invite rate regulation — a persistent tail risk for Class I railroads.
Also: "Efforts have been made over the past several years to increase federal economic regulation of the rail industry, and such efforts may continue in 2026."
4. Coal Secular Decline
Coal was 12% of revenues in 2025, down from higher levels historically. Revenue fell 8% in 2025 and 6% in 2024. Per MD&A: "Coal revenues accounted for 12% of our total railway operating revenues in 2025. We handled 78.0 million tons, or 0.7 million carloads… Our coal franchise supports the electric generation market, directly serving 18 coal-fired power plants, as well as the export, domestic metallurgical, and industrial markets." Utility coal demand continues to decline as coal-fired generation retires.
5. Labor Agreements and Safety
Per MD&A Other Matters: approximately 80% of railroad employees are covered by collective bargaining agreements. "Moratorium clauses in these new ratified agreements foreclose the parties from serving further notices to compel mandatory bargaining until November 1, 2029." Strikes/self-help are prohibited during this period — a positive.
But the Incident, the 2023 derailment at East Palestine, created fundamental safety scrutiny and all Class I railroads are now under heightened FRA oversight. Any repeat incident would have catastrophic P&L impact given NSC's thin cash cushion.
6. Capitalization Policy Judgment (Critical Audit Matter)
KPMG flagged property capitalization as the critical audit matter because the judgment between "extends useful life" (capitalize) and "maintenance" (expense) for self-constructed assets can shift reported operating expenses materially. NSC's aggressive capitalization could be flattering operating margins; the KPMG audit procedures suggest this is an area of inherent risk.
Summary
Grade: F. The grade is driven solely by C4 (Cash $1.5B vs Debt $17.3B = 9%), which is a critical check that fails automatically.
On every other dimension NSC presents as a high-quality rail operator: CFFO/NI of 1.52, FCF of $2.2B, M-Score of -2.70, no goodwill, operating ratio improving to 64.2%, and DSO declining. The Eastern Ohio Incident is migrating from liability to recovery as insurance proceeds exceed incremental costs. The accounting quality is among the best in the screen.
The F grade reflects a real structural fragility: $1.5B of cash against $17.3B of debt and $474M of Incident accruals. If the Union Pacific merger is delayed or fails, if a second safety incident occurs, or if the economy tips into recession and CFFO shrinks, the company would need to raise debt or cut capex — both of which impair future value.
The key questions for investors: (1) Does the STB approve the UP merger within the 2026 regulatory window? (2) How aggressive is UP's revised application on divestitures that might reduce the deal's strategic value? (3) Can NSC weather another Incident-scale event with only $1.5B of cash? The answers are all outside management's direct control.
