NORFOLK SOUTHERN CORP (NSC) FY 2024 MD&A

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the Consolidated Financial Statements and Notes. Refer to Item 8 “Notes to Consolidated Financial Statements” for all “Note” references.

OVERVIEW

Since 1827, Norfolk Southern Corporation and its predecessor companies have safely moved the goods and materials that drive the U.S. economy. Our dedicated team members deliver a wide variety of commodities annually for our customers, from agriculture products to consumer goods, and help them reduce carbon emissions by shipping via rail. We have the most extensive intermodal network in the eastern U.S. Our network serves a majority of the country's population and manufacturing base, with connections to every major container port on the Atlantic coast as well as major ports in the Gulf of Mexico and Great Lakes.

In 2024, we executed on various initiatives to operate our network more safely and efficiently, better serve our customers, and increase productivity in order to deliver improved financial performance. We enhanced our executive leadership team and continued to execute on our strategy of providing high-quality service to our customers to enable smart, sustainable growth and delivering on productivity initiatives. Additionally, we executed on several strategic initiatives, including the purchase of the Cincinnati Southern Railway, sales of certain railway lines, and completion of targeted rationalization and restructuring efforts, to further advance our organizational objectives. Furthermore, we continued our efforts related to the Eastern Ohio Incident (as defined and further described in Note 18 in the Notes to the Consolidated Financial Statements), including the pursuit of recoveries under our insurance programs.

Our operational improvements during the year, while handling 5% higher volumes, helped drive improvements to income from railway operations, diluted earnings per share, and railway operating ratio (a measure of the amount of operating revenues consumed by operating expenses). For the full year, we achieved an operating ratio of 66.4%, and an adjusted operating ratio of 65.8% (see our non-GAAP reconciliations beginning on page K26), both of which improved on a year-over-year basis. We remain committed to being a safe, productive, resilient, and efficient railroad with industry-competitive margins.

SUMMARIZED RESULTS OF OPERATIONS

Income from railway operations, net income and diluted earnings per share increased in 2024 compared to 2023, primarily as a result of lower railway operating expenses. The reduction in our operating expenses includes lower net expenses related to the Eastern Ohio Incident and $433 million of gains on the sale of railway lines. Railway operating revenues were slightly lower as decreased fuel surcharge revenue, an adverse mix of traffic, and decreased pricing were nearly offset by increased volumes. Our railway operating ratio improved to 66.4 percent.

Income from railway operations, net income and diluted earnings per share declined in 2023 compared to 2022, driven by expenses incurred with our response efforts to the Incident, lower railway operating revenues, and higher

K25

non-Incident-related railway operating expenses. Railway operating revenues declined 5% due to lower average revenue per unit, the result of lower fuel surcharge revenue and decreased intermodal storage service revenues partially offset by favorable pricing and mix. Additionally, lower volumes contributed to the decline in revenues. Net expenses associated with the Incident for the year 2023 were $1.1 billion. In addition to costs resulting from the Incident, railway operating expenses increased due to inflationary pressures, investments in operational resiliency, and higher service-related costs, offset partially by lower fuel prices. The decline in net income and diluted earnings per share also reflects the absence of a prior year $136 million deferred tax benefit, a result of an enactment of a change in the corporate income tax rate in the Commonwealth of Pennsylvania in 2022. Railway operating ratio deteriorated to 76.5 percent.

The following tables adjust our 2024 and 2023 U.S. Generally Accepted Accounting Principles (GAAP) financial results to exclude gains on railway line sales, restructuring and other charges (including the curtailment gain on our other postretirement benefit plan which is included in “Other income – net”), shareholder advisory costs, and a deferred income tax adjustment, all which occurred in 2024, as well as the effects of the Incident that were present in both years. The income tax effects of these non-GAAP adjustments were calculated based on the applicable tax rates to which the non-GAAP adjustments related. We use these non-GAAP financial measures internally and believe this information provides useful supplemental information to investors to facilitate making period-to-period comparisons by excluding these items. While we believe that these non-GAAP financial measures are useful in evaluating our business, this information should be considered as supplemental in nature and is not meant to be considered in isolation from, or as a substitute for, the related financial information prepared in accordance with GAAP. In addition, these non-GAAP financial measures may not be the same as similar measures presented by other companies.

K26

In the table below, references to 2024 and 2023 results and related comparisons use the adjusted, non-GAAP results from the reconciliations in the tables above.

On an adjusted basis, income from railway operations in 2024 increased due to lower adjusted railway operating expenses, with lower fuel prices, decreased costs of purchased services, and lower other expenses contributing significantly to the overall decline, and more than offsetting the decline in revenue. Lower other income-net and higher interest expense on debt contributed to net income and diluted earnings per share that were only up slightly compared to the prior year.

In 2023, on a non-GAAP basis excluding the impact of direct costs resulting from the Incident, income from railway operations decreased due to lower railway operating revenues and higher railway operating expenses. Railway operating revenues declined due to decreased fuel surcharge revenue, decreased intermodal storage revenues, and lower volume, partially offset by increased pricing and favorable mix compared to the prior year. Railway operating expenses increased due to inflationary pressures, investments in operational resiliency, and higher service-related costs, partially offset by lower fuel prices.

K27

DETAILED RESULTS OF OPERATIONS

Railway Operating Revenues

The following tables present a three-year comparison of revenues, volumes (units), and average revenue per unit by commodity group.

K28

Revenues decreased $33 million in 2024 and $589 million in 2023 compared to the prior years. Revenues decreased in 2024 as a result of lower average revenue per unit, driven by lower fuel surcharge revenue, adverse mix, and decreased pricing, partially offset by higher volume. Revenues declined in 2023 as a result of lower average revenue per unit, driven by decreases in fuel surcharge and intermodal storage revenues, and volume declines.

The table below reflects the components of the revenue change by major commodity group.

Approximately 95% of our revenue base is covered by contracts that include negotiated fuel surcharges. Fuel surcharge revenues totaled $962 million, $1.2 billion, and $1.6 billion in 2024, 2023, and 2022, respectively. The decline in fuel surcharge revenues in each period was primarily driven by fluctuations in fuel commodity prices.

For 2025, we expect that revenue will increase driven by higher volumes.

MERCHANDISE revenues increased in both 2024 and 2023 compared with the prior years. In 2024, revenues rose as volume was higher for all commodity groups and pricing gains more than offset lower fuel surcharge revenue. In 2023, revenues were slightly higher as pricing and volume gains were nearly offset by lower fuel surcharge revenue and unfavorable mix. Increased volumes in automotive and agriculture, forest and consumer shipments were partially offset by decreased chemicals shipments.

Agriculture, forest and consumer products revenues decreased slightly in 2024 but increased in 2023 compared with the prior years. In 2024, the decrease was the result of lower average revenue per unit driven by lower fuel surcharge revenue, partially offset by increased price, and increased volume. Increased volume in soybeans, corn, and feed were partially offset by lower volume in fertilizers and ethanol. Soybean volume increased due to spot opportunities. Increased corn and feed volumes were the result of customers shifting from truck to rail service to meet market demands. The decrease in fertilizer volume was driven by lower potash shipments due to customer operational issues and cost pressures. Ethanol volume declined primarily as a result of decreased demand. In 2023, higher revenues were the result of increased volume. Average revenue per unit was flat, the result of lower fuel surcharge revenue offset by pricing gains. Increases in ethanol and fertilizer shipments more than offset declines in shipments of wood chips and graphic paper. Increased market demand led to volume gains in ethanol and fertilizer. Volume declines in wood chips were due to customer mill closures, while lower market demand led to the decline in graphic paper.

Chemicals revenues increased in 2024 but decreased in 2023 compared with the prior years. In 2024, the increase in revenues was driven by higher average revenue per unit driven by increased price, partially offset by lower fuel surcharge revenue, and volume growth. Solid waste and organic chemicals volume increased due to stronger demand. These increases were slightly offset by declines in crude oil and petroleum products. Volume declines in crude oil were due to a market share shift, while declines in petroleum were related to the conclusion of a spot opportunity handled last year to support a customer during a refinery outage. In 2023, the decrease was as a result

K29

of volume declines. Reduced shipments of crude oil, organic chemicals, and natural gas liquids, more than offset the increases in solid waste and other petroleum products. Volume declines for crude oil were driven by soft demand in the energy markets. Organic chemicals and natural gas liquids volume declined as a result of lower demand. Volume gains in solid waste were due to growth with existing customers, while the gains in petroleum products were due to growth with existing customers and new business opportunities.

Metals and construction revenues were higher in 2024 but lower in 2023 compared with the prior years. In 2024, the increase was driven by higher average revenue per unit due to favorable price, partially offset by lower fuel surcharge revenue, and higher volume. Increased volume was due to higher demand in aggregates, kaolin, miscellaneous construction, and scrap metal, partially offset by lower demand for coil steel shipments. In 2023, the decline in revenue was driven by lower average revenue per unit, the result of decreased fuel surcharge revenue partially offset by increased price. Volumes were nearly unchanged as reduced shipments of kaolin and construction materials were offset by volume gains in coil steel and scrap metal. The volume declines in kaolin were largely driven by lower demand, while the declines in construction materials were due to lower demand, extended cycle times and service challenges. Gains in coil steel volume were due to increased equipment available to handle demand, while scrap metal volume increased due to higher demand.

Automotive revenues rose in both 2024 and 2023 compared with the prior years. The increase in revenues in 2024 was driven by slightly higher average revenue per unit driven by increased price, partially offset by lower fuel surcharge revenue, and slightly higher volume. Volume increases were due to improvements in equipment availability and their cycle time paired with higher demand, mostly offset by reduced production and quality holds at certain manufacturers, and extended plant shutdowns. The increase in revenues in 2023 was driven by increased volume and higher average revenue per unit, driven by favorable price. Volume increases were due to higher finished vehicle inventory levels available for rail transportation and improved equipment cycle times.

INTERMODAL revenues decreased in both 2024 and 2023 compared with the prior years. The decrease in 2024 was the result of lower average revenue per unit, driven by decreased pricing, lower fuel surcharge revenue, adverse mix, and declines in storage service revenues, partially offset by higher volume. The decrease in 2023 was the result of lower average revenue per unit, driven by reduced storage service revenues and lower fuel surcharge revenue, and decreased volume.

Intermodal units by market were as follows:

Domestic volume increased in 2024 but decreased in 2023 compared with the prior years. In 2024, volume increased due to growth in new and existing customers and improved service, partially offset by reduced demand for premium shipments. In 2023, volume declined due to a decrease in freight demand as a result of reduced consumer consumption combined with high inventories, and increased truck competition.

International volume increased in both 2024 and 2023. The increase in 2024 was driven by increased demand, growth in existing customers, and increased movements of empty containers. The increase in 2023 was driven by ocean carriers favoring inland point intermodal traffic, partially offset by a decrease in imports.

K30

COAL revenues decreased in 2024 and 2023 compared with the prior years. The decrease in 2024 was a result of lower average revenue per unit, driven by decreased pricing and lower fuel surcharge revenue, partially offset by positive mix and increased volume. The decrease in 2023 was a result of decreased volumes. Average revenue per unit was flat as lower fuel surcharge revenue and pricing declines were offset by positive mix.

As shown in the following table, total tonnage increased in 2024 but decreased in 2023 compared to prior years.

Utility coal tonnage decreased in both 2024 and 2023 compared with the prior years. The decline in 2024 was due to reduced demand from continued low natural gas prices and high stockpiles. The decrease in 2023 was due to low natural gas prices, high stockpiles, and unplanned customer outages.

Export coal tonnage increased in both 2024 and 2023 compared with the prior years. The increase in 2024 was due to growth with our customers and increased production. The increase in 2023 was a result of increased demand and coal supply.

Domestic metallurgical coal tonnage decreased in both 2024 and 2023 compared with the prior years. The decrease in 2024 was as a result of reduced customer demand. The decrease in 2023 was due to reduced coke shipments resulting from idled customer facilities.

Industrial coal tonnage increased in 2024 but decreased in 2023 compared with the prior years. The growth in 2024 was due to higher demand. The decrease in 2023 was due to reduced coal shipments related to customer sourcing changes.

K31

Railway Operating Expenses

Railway operating expenses summarized by major classifications were as follows:

In 2024, the decline in railway operating expenses reflects lower net expenses related to the Eastern Ohio incident (Note 18), higher gains on operating property sales, including certain gains on railway line sales (Note 8), and lower fuel prices, partially offset by restructuring and other charges (Note 3), and increased depreciation on our higher asset base. In 2023, expenses increased as we incurred $1.1 billion of costs related to environmental matters and legal proceedings resulting from the Incident (Note 18). Additionally, railway operating expenses reflected higher costs due to inflationary pressures, investments in operational resiliency, and higher service-related costs. Partially offsetting these increases were the impacts of lower fuel prices and the absence of retroactive wage increases recorded in 2022.

Compensation and benefits increased in 2024, reflecting changes in:

•pay rates (up $91 million),

•incentive and stock-based compensation (up $56 million),

•overtime (down $37 million),

•employee activity levels (down $68 million), and

•other (down $38 million).

In 2023, compensation and benefits increased, a result of changes in:

•employee activity levels (up $138 million),

•pay rates (up $86 million),

•overtime (up $9 million),

•incentive and stock-based compensation (down $30 million), and

•other (down $5 million).

Our employment averaged 20,200 in 2024, compared with 20,300 in 2023, and 18,900 in 2022.

K32

Purchased services includes the costs of services purchased from external vendors and contractors, including the net costs of operating joint facilities with other railroads. The decrease in purchased services in 2024 was due to lower lease costs and declines in technology-related and operational expenses, partially offset by higher volume-related expenses and Conrail-related activity. The increase in purchased services in 2023 was due to higher technology-related costs, increased operational and transportation expenses, and higher engineering activity.

Equipment rents, which includes our cost of using equipment (mostly freight cars) owned by other railroads or private owners less the rent paid to us for the use of our equipment, increased in both periods. In 2024, the increase was due to increased automotive and intermodal equipment expenses as a result of higher volumes. In 2023, the increase was due to increased intermodal equipment expenses, higher freight car lease costs, and decreased equity in TTX Company's (TTX) earnings.

Fuel expense, which includes the cost of locomotive fuel as well as other fuel used in railway operations, decreased in both 2024 and 2023. The decrease in both periods was due to lower locomotive fuel prices (down 15% in 2024 and 20% in 2023), which decreased fuel expense by $159 million and $275 million in 2024 and 2023, respectively. Locomotive fuel consumption was down in 2024 and nearly flat in 2023 compared to prior periods. We consumed 373 million gallons of diesel fuel in 2024, compared with 377 million gallons in 2023 and 376 million gallons in 2022.

Depreciation expense increased in both periods compared to the prior years, reflecting reinvestment in our infrastructure, rolling stock, and technology.

Materials expense increased in both 2024 and 2023. The increase in 2024 was due to higher freight car repairs expense, partially offset by lower locomotive materials spending. The increase in 2023 was due to increased locomotive, freight car, and track materials costs.

Claims expense includes costs related to personal injury, property damage, and environmental matters. Claims expense decreased in both 2024 and 2023 compared to the prior years. The decrease in 2024 is the result of lower personal injury case development and declines in lading and property damage expenses. These were partially offset by the absence of a prior-year claims-related recovery and higher insurance costs. The decrease in 2023 was primarily the result of lower personal injury case development, lower costs related to environmental remediation matters unrelated to the Incident, and a claims-related recovery.

Other expense decreased in 2024 primarily due to increased gains from operating property sales, lower non-income-based taxes, and lower relocation and travel-related expenses. Gains from operating property sales includes $433 million of gains on the sale of railway lines in the states of Virginia and North Carolina. These transactions are described further in Note 8 in the Notes to Consolidated Financial Statements. The increase in 2023 was primarily due to lower gains from operating property sales and increased travel-related expenses. Gains from operating property sales amounted to $490 million, $43 million, and $76 million in 2024, 2023, and 2022, respectively.

Restructuring and other charges

In 2024, we recorded $183 million in restructuring and other charges. During the year, we completed voluntary and involuntary separation programs that reduced our management workforce. Additionally, we ceased development of certain technology projects that had not been placed into service. We also wrote down certain specialized equipment to its net realizable value, reflecting the planned disposition of that asset class. Additionally, we incurred costs associated the appointment of our chief operating officer. See Notes 3 and 13 in the Notes to Consolidated Financial Statements for additional information.

K33

Eastern Ohio incident

During 2024, we incurred net expenses of $325 million associated with the Incident, including additional costs associated with environmental matters and legal proceedings. The total amount recorded in 2024 is net of $650 million of insurance recoveries, resulting from claims made under our insurance policies in effect at the time of the Incident. During 2023, we recorded $1.1 billion for costs primarily associated with environmental matters and legal proceedings. We recorded $101 million of recoveries from claims made under our insurance policies, which are included in the total amount recorded in 2023. Our cash expenditures attributable to the Incident, net of insurance proceeds received, were $119 million and $652 million in 2024 and 2023, respectively, and which are presented in “Net cash provided by operating activities” on the Consolidated Statements of Cash Flows. For further details regarding the Incident, see Note 18 in Notes to Consolidated Financial Statements.

Other Income – Net

Other income – net decreased in 2024 but increased in 2023. The decrease in 2024 reflects costs associated with shareholder matters, lower returns on corporate-owned life insurance (COLI), and higher pension and other postretirement benefits expense, partially offset by a $20 million curtailment gain on our other postretirement benefit plan as a result of our voluntary and involuntary separation programs (Note 3). The increase in 2023 was the result of higher net returns on COLI and increased interest income, partially offset by lower gains from non-operating property sales.

Income Taxes

The effective income tax rate was 21.2% in 2024, compared with 21.3% in 2023 and 20.8% in 2022.  The current year reflects a $15 million deferred income tax benefit due to a change in a state corporate income tax rate and a $27 million deferred income tax benefit from subsidiary restructuring. These benefits were partially offset by the absence of certain business tax credits recognized in the prior year. The 2023 effective rate benefited from tax credits and higher COLI returns offset by reduced benefits from stock-based compensation. The effective income tax rate in 2022 reflects favorable benefits associated with stock-based compensation and various state law changes (Note 5).

For 2025, we expect an effective income tax rate between 23% and 24%.

FINANCIAL CONDITION, LIQUIDITY, AND CAPITAL RESOURCES

Cash provided by operating activities, our principal source of liquidity, was $4.1 billion in 2024, $3.2 billion in 2023, and $4.2 billion in 2022. The increase in 2024 reflects improved operating results. The decrease in 2023 reflects lower operating results, offset in part by changes in working capital. We had negative working capital of $357 million at December 31, 2024 and working capital of $639 million at December 31, 2023. Cash and cash equivalents totaled $1.6 billion at both December 31, 2024, and December 31, 2023. We expect that cash on hand combined with cash provided by operating activities will be sufficient to meet our ongoing obligations. In addition, we believe our currently-available borrowing capacity, access to additional financing, ability to reduce shareholder distributions, and ability to moderate or defer property additions provide additional flexibility to meet our ongoing obligations in the short- and long-term.

K34

Contractual obligations at December 31, 2024, including those that may have material cash requirements, include interest on fixed-rate long-term debt, long-term debt (Note 10), unconditional purchase obligations (Note 18), long-term advances from Conrail Inc. (Conrail) (Note 7), operating leases (Note 11), agreements with Consolidated Rail Corporation (CRC) (Note 7), and unrecognized tax benefits (Note 5).

* This amount is shown in the 2030 and Subsequent column because the year of settlement cannot be reasonably estimated.

Off balance sheet arrangements consist primarily of unrecognized obligations, including future interest payments on fixed-rate long-term debt and unconditional purchase obligations, which are included in the table above. Additionally, in connection with our ownership of an equity method investment, we have the option to acquire an intermodal terminal located in the southern U.S. for an amount that will be determined subsequent to the potential exercise of that option. Our option to purchase the terminal expires in the second quarter of 2025.

Cash used in investing activities was $2.8 billion in 2024, $2.2 billion in 2023, and $1.6 billion in 2022.  The increase in 2024 was driven by the acquisition of the assets of the CSR, partially offset by higher borrowings against our COLI policies and increased proceeds from property sales. Please see Note 8 in the Notes to Consolidated Financial Statements for additional details on certain railway line sales and a discussion of the acquisition of the CSR assets. In 2023, the increase was primarily driven by higher property additions and lower proceeds from property sales.

Capital spending and track and equipment statistics can be found within the “Railway Property” section of Part I of this report on Form 10-K. For 2025, we expect property additions to approximate $2.2 billion.

Cash used in financing activities was $1.2 billion in 2024, while cash provided by financing activities was $115 million in 2023, and cash used in financing activities was $3.0 billion in 2022.  The increase in cash used in financing activities in 2024 reflects lower proceeds from borrowing partially offset by the absence of repurchases of Common Stock. In 2023, the increase in cash provided by financing activities reflects lower repurchases of Common Stock and increased proceeds from borrowings, partially offset by higher debt repayments.

We did not repurchase any Common Stock during 2024, while we repurchased $622 million in 2023 and $3.1 billion in 2022, which resulted in the retirement of 2.8 million and 12.6 million shares in 2023 and 2022, respectively. As of December 31, 2024, $6.9 billion remains authorized by our Board of Directors for repurchase. The timing and volume of future share repurchases will be guided by our assessment of market conditions and other pertinent factors. Repurchases may be executed in the open market, through derivatives, accelerated repurchase and other negotiated transactions and through plans designed to comply with Rule 10b5-1(c) and Rule 10b-18 under the

K35

Securities and Exchange Act of 1934. Any near-term purchases under the program are expected to be made with internally-generated cash, cash on hand, or proceeds from borrowings.

In June 2024, we entered into an agreement that provides us the ability to issue up to $800 million of unsecured commercial paper and is backed by our credit agreement. The unsecured short-term commercial paper program provides for borrowing at prevailing rates and includes covenants. At December 31, 2024, we had no outstanding commercial paper.

In May 2024, we renewed our accounts receivable securitization program with a maximum borrowing capacity of $400 million. Amounts under our accounts receivable securitization program are borrowed and repaid from time to time in the ordinary course for general corporate and cash management purposes. The term of our accounts receivable securitization program expires in May 2025. We had no amounts outstanding under this program and our available borrowing capacity was $400 million at both December 31, 2024 and December 31, 2023.

In January 2024, we renewed and amended our $800 million credit agreement. The amended agreement expires in January 2029, and provides for borrowings at prevailing rates and includes covenants. We had no amounts outstanding under this facility at either December 31, 2024 or December 31, 2023, and we are in compliance with all of its covenants.

In January 2024, we also entered into a term loan credit agreement that established a 364-day, $1.0 billion, unsecured delayed draw term loan facility under which we could borrow for general corporate purposes. The term loan credit agreement provided for borrowing at prevailing rates and included covenants that align with the $800 million credit agreement. The term loan expired undrawn in October 2024.

In addition, we have investments in general purpose COLI policies and had the ability to borrow against these policies. We had borrowed $605 million against these policies at December 31, 2024 and no amounts borrowed at December 31, 2023. Our remaining borrowing capacity was $40 million and $640 million at December 31, 2024 and December 31, 2023, respectively. In January 2025, we repaid all amounts that were borrowed against these policies at December 31, 2024.

Our debt-to-total capitalization ratio was 54.6% at December 31, 2024, compared with 57.3% at December 31, 2023. We discuss our credit agreement and our accounts receivable securitization program in Note 10. Upcoming annual debt maturities are also disclosed in Note 10.  Overall, our goal is to maintain a capital structure with appropriate leverage to support our business strategy and provide flexibility through business cycles.

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period.  These estimates and assumptions may require judgment about matters that are inherently uncertain, and future events are likely to occur that may require us to make changes to these estimates and assumptions.  Accordingly, we regularly review these estimates and assumptions based on historical experience, changes in the business environment, and other factors we believe to be reasonable under the circumstances.

Incident Contingencies

We are currently involved in certain environmental response and remediation activities and subject to numerous legal proceedings and regulatory inquiries and investigations relating to the Incident. We have accrued estimates of the probable and reasonably estimable costs for the resolution of these matters. Our environmental estimates are based upon types of remediation efforts currently anticipated, the volume of contaminants in the impacted areas, and governmental oversight and other costs, amongst other factors. Estimates associated with the legal proceedings to

K36

which we are subject are based on information that is currently available, including but not limited to an assessment of the proceedings and the potential and likely results of such proceedings.

Our current estimates of future environmental cleanup and remediation liabilities related to the Incident may change over time due to various factors, including but not limited to, the nature and extent of required future cleanup and removal activities (including those resulting from soil, water, sediment, and air assessment and investigative activities conducted at the site), and the extent and duration of governmental oversight, amongst other factors. Additionally, the final outcome of any of the legal proceedings and regulatory inquiries and investigations cannot be predicted with certainty, and developments related to the progress of such legal proceedings, inquiries, or investigations or other unfavorable or unexpected outcomes could result in additional costs or new or additionally accrued amounts that could be material to our results of operations in any particular year. Furthermore, certain costs may be recoverable under our insurance policies in effect at the date of the Incident or from third parties. Any amounts that are recoverable under our insurance policies or from third parties will be reflected in the period in which recovery is considered probable.

See Note 18 for more detailed information as it pertains to these contingencies.

Pensions and Other Postretirement Benefits

Accounting for pensions and other postretirement benefit plans requires us to make several estimates and assumptions (Note 13).  These include the expected rate of return from investment of the plans’ assets and the expected retirement age of employees as well as their projected earnings and mortality.  In addition, the amounts recorded are affected by changes in the interest rate environment because the associated liabilities are discounted to their present value.  We make these estimates based on our historical experience and other information we deem pertinent under the circumstances (for example, expectations of future stock market performance).  We utilize an independent actuarial consulting firm’s studies to assist us in selecting appropriate actuarial assumptions and valuing related liabilities.

For 2024, we assumed a long-term investment rate of return of 8.0%, which was supported by our long-term total rate of return on pension plan assets since inception, as well as our expectation of future returns. A one-percentage point decrease to this rate of return assumption would result in a $24 million increase in annual pension expense. We review assumptions related to our defined benefit plans annually, and while changes are likely to occur in assumptions concerning retirement age, projected earnings, and mortality, they are not expected to have a material effect on our net pension expense or net pension liability in the future. The net pension liability is recorded at net present value using discount rates that are based on the current interest rate environment in light of the timing of expected benefit payments.  We utilize analyses in which the projected annual cash flows from the pension and postretirement benefit plans are matched with yield curves based on an appropriate universe of high-quality corporate bonds.  We use the results of the yield curve analyses to select the discount rates that match the payment streams of the benefits in these plans. A one-percentage point decrease to this discount rate assumption would result in a $14 million increase in annual pension expense.

Properties and Depreciation

Most of our assets are long-lived railway properties (Note 8). “Properties” are stated principally at cost and are depreciated using the group method whereby assets with similar characteristics, use, and expected lives are grouped together in asset classes and depreciated using a composite depreciation rate. See Note 1 for a more detailed discussion of assumptions and estimates.

Expenditures, including those on leased assets, that extend an asset’s useful life or increase its utility are capitalized. Expenditures capitalized include those that are directly related to a capital project and may include materials, labor, and other direct costs, in addition to an allocable portion of indirect costs that relate to a capital project. A significant portion of our annual capital spending relates to self-constructed assets. Costs related to repairs and

K37

maintenance activities that, in our judgment, do not extend an asset’s useful life or increase its utility are expensed when such repairs are performed.

Depreciation expense for 2024 totaled $1.4 billion.  Our composite depreciation rates for 2024 are disclosed in Note 8; a one-year increase (or decrease) in the estimated average useful lives of depreciable assets would have resulted in an approximate $51 million decrease (or increase) to annual depreciation expense.

Personal Injury

Claims expense, included in “Materials and other” in the Consolidated Statements of Income, includes our estimate of costs for personal injuries.

To aid in valuing our personal injury liability and determining the amount to accrue with respect to such claims during the year, we utilize studies prepared by an independent actuarial consulting firm. The actuarial firm studies our historical patterns of reserving for claims and subsequent settlements, taking into account relevant outside influences. We adjust the liability quarterly based upon our assessment and the results of the study. The accuracy of our estimate of the liability is subject to inherent limitation given the difficulty of predicting future events and, as such, the ultimate loss sustained may vary from the estimated liability recorded.

See Note 18 for a more detailed discussion of the assumptions and estimates we use for personal injury.

Income Taxes

Our net deferred tax liability totaled $7.4 billion at December 31, 2024 (Note 5).  This liability is estimated based on the expected future tax consequences of items recognized in the financial statements.  After application of the federal statutory tax rate to book income, judgment is required with respect to the timing and deductibility of expenses in our income tax returns.  For state income and other taxes, judgment is also required with respect to the apportionment among the various jurisdictions. A valuation allowance is recorded if we expect that it is more likely than not that deferred tax assets will not be realized. We have a $42 million valuation allowance on $467 million of deferred tax assets as of December 31, 2024, reflecting the expectation that substantially all of these assets will be realized.

OTHER MATTERS

Labor Agreements

Approximately 80% of our railroad employees are covered by collective bargaining agreements with various labor unions. Pursuant to the Railway Labor Act (RLA), these agreements remain in effect until new agreements are reached, or until the bargaining procedures mandated by the RLA are completed. Moratorium provisions in the labor agreements govern when the railroads and unions may propose changes to the agreements. We largely bargain nationally in concert with other major railroads, represented by the National Carriers’ Conference Committee (NCCC).

Under current moratorium provisions, neither party was permitted to serve notice to compel a new round of mandatory collective bargaining until November 1, 2024. In the months prior to the opening of the current national bargaining round, we engaged in voluntary local discussions with our labor unions and, as a result, reached local tentative agreements with ten of our thirteen unions. A majority of those tentative agreements were subsequently ratified by union membership and became effective January 1, 2025, foreclosing the parties from serving new notices to compel mandatory bargaining until November 1, 2029.

For those unions with whom we have not yet reached a ratified agreement, the NCCC, on behalf of Norfolk Southern, sent bargaining notices on November 1, 2024, to commence mandatory direct negotiations as prescribed under the RLA. Even if the parties are unable to reach voluntary agreement during this first phase of RLA

bargaining, self-help (e.g., a strike or other work stoppage) related to this collective-bargaining process remains prohibited by law until a lengthy series of additional procedures mandated by the RLA, including federal mediation, are exhausted.

Market Risks

We manage overall exposure to fluctuations in interest rates by issuing both fixed- and floating- rate debt instruments. At December 31, 2024, we have no outstanding debt subject to interest rate fluctuations. Market risk for fixed-rate debt is estimated as the potential increase in fair value resulting from a one-percentage point decrease in interest rates as of December 31, 2024 and amounts to an increase of approximately $1.5 billion to the fair value of our debt at December 31, 2024. We consider it unlikely that interest rate fluctuations applicable to these instruments will result in a material adverse effect on our financial position, results of operations, or liquidity.

New Accounting Pronouncements

For a detailed discussion of new accounting pronouncements, see Note 1.

Inflation

In preparing financial statements, GAAP requires the use of historical cost that disregards the effects of inflation on the replacement cost of property.  As a capital-intensive company, we have most of our capital invested in long-lived assets.  The replacement cost of these assets, as well as the related depreciation expense, would be substantially greater than the amounts reported on the basis of historical cost.

FORWARD-LOOKING STATEMENTS
