YoY shift: Lean +

Year-over-year tone shift - average net-tone change across Risk Factors and MD&A vs the prior 10-K. This filing is 0.37pp more bullish than last year's.

Why YoY instead of absolute: the LM lexicon has ~6.6× more negative words than positive (legal/risk-disclosure language is heavy on hedging), so every 10-K reads bearish on raw tone. Year-over-year change strips that bias and surfaces the actual shift in management's framing.

Item 1A. Risk Factors

The risks set forth in the following risk factors could have a material adverse effect on our financial position, results of operations, or liquidity in a particular year or quarter, and could cause those results to differ materially from those expressed or implied in our forward-looking statements. The information set forth in this Item 1A “Risk Factors” should be read in conjunction with the rest of the information included in this annual report, including

Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 8 “Financial Statements and Supplementary Data.” We have experienced a number of the risks described below in connection with the Incident and the Incident Proceedings (defined below). The risks described below should be read in conjunction with the information regarding the Incident and Incident Proceedings provided in Note 19 in Item 8 “Notes to Consolidated Financial Statements.”

RISKS RELATED TO THE MERGERS

We have identified certain additional risk factors in connection with the Mergers. For additional information concerning these risks, uncertainties and assumptions, please refer to the section entitled “Risk Factors” included in our proxy statement filed with the SEC on October 1, 2025.

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. The completion of the Mergers is subject to a number of conditions, including, among others, the receipt of the requisite regulatory approvals, which make the completion of the Mergers and timing thereof uncertain. Also, either Union Pacific or the Company may terminate the Merger Agreement if the Mergers have not been consummated by the end date (subject to an automatic extension in certain circumstances), except that this right to terminate the Merger Agreement will not be available to any party whose failure to perform any obligation under the Merger Agreement has been the primary cause of the failure of the Mergers to be consummated on or before that date.

If the Mergers are not completed, the Company’s ongoing business may be materially adversely affected and, without realizing any of the benefits of having completed the Mergers, the Company will be subject to a number of risks, including the following:

• the market price of the Company’s Common Stock could decline;

• the Company could owe substantial termination fees to Union Pacific under certain circumstances;

• if the Merger Agreement is terminated and the Union Pacific board or the Company’s board seeks another business combination, Union Pacific shareholders and Norfolk Southern shareholders cannot be certain that Union Pacific or the Company will be able to find a party willing to enter into a transaction on terms equivalent to or more attractive than the terms that the other party has agreed to in the Merger Agreement;

• time, resources, and costs committed by the Company’s management team to matters relating to the Mergers could otherwise have been devoted to pursuing other beneficial opportunities;

• negative reactions from the financial markets or from its customers (certain of whom have and may continue to diversify their distribution networks, including in response to actions by our competitors), suppliers, employees, labor unions, or other business partners; and

• the Company will be required to pay its respective costs relating to the Mergers, such as legal, accounting, financial advisory, and printing fees, whether or not the Mergers are completed.

In addition, if the Mergers are not completed, the Company could be subject to litigation related to any failure to complete the Mergers or related to any enforcement proceeding commenced against the Company to perform its obligations under the Merger Agreement, and whether or not any such litigation has any merit, the cost of defending such litigation may be significant. The materialization of any of these risks could adversely impact the Company’s ongoing business.

Similarly, delays in the completion of the Mergers could, among other things, result in additional transaction costs, loss of revenue, or other negative effects associated with uncertainty about completion of the Mergers.

The Mergers are subject to the receipt of the requisite regulatory approvals, which requisite regulatory approvals may never be obtained, therefore preventing completion of the Mergers. In addition, in granting such approvals, regulatory authorities may impose conditions that could have a significant adverse effect on the Company or the combined company and the expected benefits of the Mergers therefore preventing completion of the Mergers. Before the Mergers may be completed, the requisite regulatory approvals must have been obtained, including STB approval. 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 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. Subject to the terms and conditions of the Merger Agreement, Union Pacific and the Company have each agreed to use their reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with each other in doing, all things necessary, proper, or advisable to cause the conditions to closing set forth in the Merger Agreement to be satisfied and to consummate and make effective the Mergers and the other transactions contemplated by the Merger Agreement prior to the end date, except that Union Pacific and its subsidiaries are not required to take, or commit to take, or agree to or accept any “materially burdensome regulatory condition.” For purposes of the foregoing, “reasonable best efforts” includes, among others, (i) proposing, negotiating, committing to, and effecting, by consent decree, hold separate order, or otherwise, the sale, divestiture, license, hold separate, or disposition of any and all of the share capital or other equity interest, assets, products, or businesses of Union Pacific and its subsidiaries or of the Company and its subsidiaries and (ii) otherwise taking or committing to take any actions that after the first effective time would limit Union Pacific’s or its subsidiaries’ freedom of action with respect to, or their ability to retain, or otherwise agreeing to any restriction, requirement, or limitation with respect to their or one or more of their subsidiaries’ assets, products, or businesses, in each case as may be required in order to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order, or other order that would otherwise have the effect of preventing or delaying the closing. The STB and other regulatory and governmental authorities may impose requirements, concessions, and other conditions on the granting of such approvals. If such regulatory and governmental authorities seek to impose such requirements, concessions, or conditions, lengthy negotiations may ensue among such authorities, Union Pacific and the Company. Such requirements, concessions, and conditions and the process of obtaining regulatory approvals could have the effect of delaying completion of the Mergers and such requirements, concessions, and conditions may not be identified or satisfied for an extended period of time following the Union Pacific special meeting and the Company’s special meeting. Such requirements, concessions and conditions may also impose additional costs or limitations on the combined company following the completion of the Mergers and the parties have agreed to accept such requirements, concessions, and conditions, even if significant, subject to the agreed-upon materially burdensome regulatory condition limitation in favor of Union Pacific. These requirements, concessions, and conditions may therefore reduce the anticipated benefits of the Mergers, including synergies, which could also have a significant adverse effect on the combined company’s business and cash flows and results of operations, and

neither Union Pacific nor the Company can predict what, if any, requirements, concessions, and conditions may be required by regulatory or governmental authorities whose approvals are required. The requisite regulatory approvals may not be obtained at all, may not be obtained in a timely fashion, and may contain conditions on the completion of the Mergers.

In addition, under existing law, railroad competitors and customers of Union Pacific and the Company and other interested parties may intervene to oppose the STB application or seek protective conditions in the event approval by the STB is granted, which might affect the decision of the STB, delay the approval process, or reduce the anticipated benefits of the Mergers. Furthermore, if the STB does not provide final approval or imposes conditions on its approval in a final order, and Union Pacific and the Company decide to appeal such final order from the STB, any such appeal might not be resolved for a substantial period of time after the entry of such order by the STB.

The Company is subject to business uncertainties and contractual restrictions while the Mergers are pending, which could adversely affect the Company’s business and operations. In connection with the pendency of the Mergers, some customers, suppliers, and other persons with whom the Company has a business relationship have or may delay or defer certain business decisions or terminate, change, or renegotiate their relationships with the Company, as the case may be, as a result of the Mergers or responsive actions taken by one or more of our competitors, which could negatively affect the Company’s revenues, earnings, and cash flows, as well as the market price of the Company’s Common Stock, regardless of whether the Mergers are completed.

Under the terms of the Merger Agreement, the Company is subject to certain restrictions on the conduct of its business prior to completing the first Merger, which may adversely affect its ability to execute certain of its business strategies, including the ability in certain cases to enter into or amend contracts, acquire or dispose of assets, incur indebtedness, incur capital expenditures, settle litigation, amend organizational documents, declare dividends, enter new business lines, and invest in third parties. Such limitations could adversely affect the Company’s businesses and operations prior to the completion of the Mergers.

Uncertainties associated with the Mergers may cause a loss of management personnel and other key employees, and the Company may have difficulty attracting and motivating management personnel and other key employees. The Company is dependent on the experience and industry knowledge of its management personnel and other key employees to execute its business plans. The combined company’s success after the completion of the Mergers will depend in part upon the ability of the Company to attract and retain key management personnel and other key employees. Prior to completion of the Mergers, current and prospective employees of the Company may experience uncertainty about their roles within the combined company following the completion of the Mergers, which may have an adverse effect on the ability of the Company to attract or retain management personnel and other key employees.

Each of the risks described above may be exacerbated by delays or other adverse developments with respect to the completion of the Mergers.

INCIDENT RISKS

As defined and as further described in Note 19 in Item 8 “Notes to Consolidated Financial Statements,” there was an Incident that occurred in the first quarter of 2023 that consisted of a February 3, 2023 train derailment in East Palestine, Ohio that included 11 non-Company-owned tank cars containing hazardous materials, fires associated with the derailment that threatened certain of the tank cars, and a controlled vent and burn procedure conducted on February 6, 2023 on five of the derailed tank cars, all of which contained vinyl chloride. As a result of the Incident, we became subject to numerous legal, regulatory, legislative, and other proceedings related thereto, including but not limited to, the National Transportation Safety Board (NTSB) Investigation, the FRA Incident Investigation, the FRA Safety Assessment, the U.S. Department of Justice (DOJ) Complaint, the Ohio Complaint, the Incident Lawsuits, the Shareholder Matters, and the Incident Inquiries and Investigations (each as defined in Note 19 in Item 8 “Notes to Consolidated Financial Statements”) in addition to other proceedings, actions, or potential changes in response to the Incident, including but not limited to those related to, among other items, train size, train length,

train composition, crew size, or detection systems (collectively, the “Incident Proceedings”). Set forth below are additional risks pertaining to an investment in the Company that are related to the Incident and the Incident Proceedings.

The costs, liabilities, fines, penalties, and/or financial impact resulting from or related to the Incident or the Incident Proceedings have been significant to date, may exceed expected or accrued amounts, and have and can be expected to continue to negatively affect our financial results. We have incurred and will continue to remain subject to incurring significant costs, liabilities, fines, and penalties related to the Incident and the Incident Proceedings, including amounts that may have a material adverse effect on our financial position, results of operations, or liquidity.

While we have accrued estimates of probable and reasonably estimable liabilities with respect to the Incident and the Incident Proceedings, we cannot predict the final outcome or estimate the reasonably possible range of loss with certainty, and such estimates may change over time due to a variety of factors, including but not limited to those set forth in Note 19 in Item 8 “Notes to Consolidated Financial Statements” or other unfavorable or unexpected developments or outcomes which could result in our current estimates being insufficient. These estimated amounts also do not include any estimate of loss for specific items for which we believe a loss is either not probable or not reasonably estimable for the reasons set forth in Note 19 in Item 8 “Notes to Consolidated Financial Statements.” As a result, our currently accrued amounts of estimated liabilities may be insufficient, and any additional, new or updated accruals could have a material adverse effect on our results of operations or financial position.

New or additional governmental regulation and/or operational changes resulting from or related to the Incident or the Incident Proceedings may negatively impact us, our customers, the rail industry, or the markets we serve. The legislative, regulatory, operational, or other actions taken, protocols adopted (including by us), or changes resulting from the Incident or any of the Incident Proceedings may, either individually or in the aggregate, have a material adverse effect on us, our customers, the rail industry, or the markets we serve. We also face risks from requirements that may be imposed by the government in resolution of government actions, including, for example, restrictions on our methods of operations. Our inability to comply with the requirements of any new or additional laws, regulations, or operating protocols resulting from or related to the Incident or the Incident Proceedings may have a material adverse effect on our financial position, results of operations, liquidity, or operations.

REGULATORY AND LEGISLATIVE RISKS

Governmental legislation, regulation, and Executive Orders over commercial, operational, tax, safety, security, or cybersecurity matters could negatively affect us, our customers, the rail industry, or the markets we serve. Congress can enact laws, agencies can promulgate regulations, and Executive Orders can be issued that increase or alter regulation in a way that negatively affects us, our customers, the rail industry, or the markets we serve. Railroads presently are subject to commercial and operational regulation by the STB, which has jurisdiction to varying extents over rates, routes, customer access provisions, fuel surcharges, conditions of service, and the extension or abandonment of rail lines.

The STB also has jurisdiction over the consolidation, merger, or acquisition of control of and by rail common carriers. Additional, updated, or changed oversight and regulation of the rail industry by Congress or the STB, whether under new, existing, amended, or repealed laws or regulations, including but not limited to those pertaining to reciprocal switching, if imposed, could have a significant negative impact on our ability to negotiate prices for rail services, on our railway operating revenues, and on the efficiency, conduct, or complexity of our operations. Such additional or updated industry regulation, as well as enactment of any new or updated tax laws, could also negatively impact cash flows from our operating activities and, therefore, result in reduced capital spending on our rail network or abandonment of lines.

Railroads are also subject to the enactment of laws by Congress and regulation by the DOT (including the FRA) and the DHS (including the TSA), which regulate many aspects of our operations related to safety, security, and

cybersecurity. Additional or updated safety, security, or cybersecurity regulation by Congress, the DOT, or DHS could have a negative impact on our business and the efficiency, conduct, or complexity of our operations including (but not limited to) increased operating costs, capital expenditures, claims, and litigation.

Our inability to comply with, or operational practices and costs necessary to adhere to, the requirements of existing or updated laws, regulations, or Executive Orders that govern our operations or the rail industry, including but not limited to those pertaining to commercial, operational, tax, safety, security, or cybersecurity matters, as such requirements may be interpreted or enforced from time to time (such as in connection with a pending regulatory or other legal proceedings or lawsuits), could have a material adverse effect on our financial position, results of operations, or liquidity.

We are addressing multiple governmental actions as a result of the Incident, as noted in “Incident Risks” above.

Federal and state environmental laws and regulations could negatively impact us and our operations. Our operations are subject to extensive federal, state and local environmental laws and regulations concerning, among other things: emissions to the air; discharges to waterways or groundwater supplies; handling, storage, transportation, use, and disposal of waste and other materials; and, the cleanup of hazardous material or petroleum releases. The risk of incurring environmental liability, for acts and omissions, past, present, and future, is inherent in the railroad business. This risk includes property owned by us, whether currently or in the past, that is or has been subject to a variety of uses, including our railroad operations and other industrial activity by past owners or our past and present tenants.

Environmental problems that are latent or undisclosed may exist on these properties, and we could incur environmental liabilities or costs, the amount and materiality of which cannot be estimated reliably at this time, with respect to one or more of these properties. Moreover, lawsuits and claims involving other unidentified environmental sites and matters are likely to arise from time to time.

Our inability to comply with the extensive federal, state and local environmental laws and regulations to which we are subject could result in significant liabilities, fines, or sanctions, including those related to the investigation or remediation of known and unknown environmental contamination, or otherwise adversely impact our operations.

U.S. international trade relationships may adversely impact our customers, our industry, and our business. We transport a significant number of shipments that have either been imported into the U.S. or are destined for export from the U.S. Trade discussions and arrangements between the U.S. and various of its trading partners are fluid, and existing and future trade agreements are, and are expected to continue to be, subject to a number of uncertainties, including the imposition of new tariffs or adjustments and changes to the products covered by existing tariffs. Any decision by the U.S. government to adopt actions such as border taxes on imports, an increase in customs duties or tariffs, or the renegotiation of U.S. trade agreements, or any other action that could have a negative impact on international trade, including corresponding actions taken by other countries in response to U.S. governmental actions, could cause a reduction in the volume of shipments by many of our customers. Any changes in tax and trade policies in the U.S. and corresponding actions by other countries could adversely impact our financial performance.

In addition, compliance with any new laws, regulations, or policies with regard to any of the foregoing may increase our operating costs or require significant capital expenditures. Any failure to comply with applicable laws, regulations or policies in the U.S. or other countries could result in substantial fines or possible revocation of our authority to conduct our operations, which could materially adversely affect us.

OPERATIONAL RISKS

A significant adverse event on our network may significantly impede our ability to operate and serve our customers. The nature of our operations inherently comes with the risk that one or more significant adverse events or outages may occur on or impact our network resulting in our inability or restricted ability to provide rail transportation services to our customers. These events include but are not limited to, a mainline accident, a hazardous material discharge, a climate-related network outage, or a technology-related network outage. Any one or more of these incidents could expose us to significant operational and managerial challenges, as well as reputational damage, requiring a significant amount of time and focus of our Board and management team, as well as significant lost revenues, expenses, liabilities, fines, and penalties, including amounts that may have a material adverse effect on our financial position, results of operations, or liquidity. One or more of these events may also result in subsequent legislative, regulatory, operational or other responsive actions taken, changes or protocols adopted (including by us), or requirements imposed that may, either individually or in the aggregate, have a material adverse effect on our financial position, results of operations, liquidity, or operations, or on our customers, the rail industry, or the markets we serve.

If we are unable to successfully execute on our strategic initiatives, our business and future results of operations may suffer. Our growth strategy includes increasing the volume of shipments moving through our railway networks. We are reliant on the success of our strategic plans and initiatives to execute on this growth strategy, as well as to help offset increasing costs. These strategic plans include marketing, service, growth, and productivity initiatives. The timely and effective execution of our strategies are dependent upon, among other factors, (i) our ability to maintain satisfactory relations with our customers, employees, and other key stakeholders, (ii) our ability to effectively control costs, (iii) the progress and success of our safety programs and inspection technologies, and (iv) our ability to timely and effectively maintain and upgrade technology systems and other infrastructure for our railway networks. Our failure to successfully execute on our strategic initiatives may expose us to a number of risks, including, that our projected volume growth may differ from actual results, and prior capital investments based on our projections may contribute to excess capacity that could negatively impact our profitability.

As a common carrier by rail, we must offer to transport hazardous materials, which exposes us to significant costs and claims. Transportation of certain hazardous materials or third party-owned equipment (typically used to transport such materials) creates risks of significant losses in terms of personal injury and property (including environmental) damage and compromises critical parts of our rail network. The costs of a catastrophic rail accident involving hazardous materials or third party-owned equipment could exceed our insurance coverage. We have obtained insurance for potential losses for third-party liability and first-party property damages (see Note 19 in Item 8 “Notes to Consolidated Financial Statements”); however, insurance is available from a limited number of insurers and may not continue to be available or, if available, may not be obtainable on terms acceptable to us. Any future legislation preventing the transportation of hazardous materials through specific cities could have negative impacts including increased network congestion and operating costs, reduced operating efficiency, and increased risk of an accident involving hazardous materials.

With regard to the risks arising from the transportation of hazardous materials, the Incident and the Incident Proceedings have given rise to significant costs to us and impacts on our rail network, as noted in “Incident Risks” above. With respect to third party-owned equipment, the primary risk arises from the potential for a latent defect we are unable to identify despite robust safety inspection protocols.

We face competition from other transportation providers. We are subject to competition from motor carriers, railroads and, to a lesser extent, ships, barges, and pipelines, on the basis of transit time, pricing, and quality and reliability of service. While we have primarily used internal resources to build or acquire and maintain our rail system, trucks and barges have been able to use public rights-of-way maintained by public entities. Any future improvements, expenditures, legislation, or regulation changing or materially increasing the efficiency or reducing the cost of one or more alternative modes of transportation in the regions in which we operate (such as granting materially greater latitude for motor carriers with respect to size or weight limitations or adoption and utilization of

autonomous commercial vehicles) could have a material adverse effect on our ability to compete with other modes of transportation. In addition, our industry continues to evolve, including customer demands for faster transit times and increased visibility, and the potential for increased competition (due to growth in the market, competitors with improved financial capacity or technology, or business combinations resulting in one or more competitors providing a wider variety of services and products at competitive prices) which may, either individually or in the aggregate, have a material adverse effect on our business or results of operations.

Capacity constraints could negatively impact our service and operating efficiency. We have experienced and may again experience capacity constraints on our rail network related to employee or equipment shortages, increased demand for rail services, severe weather, congestion on other railroads, including passenger activities, or impacts from changes to our network structure or composition. Such constraints could result in operational inefficiencies or adversely affect our operations.

Significant increases in demand for rail services could result in the unavailability of qualified personnel and resources like locomotives. Changes in workforce demographics, training requirements, and availability of qualified personnel, particularly for engineers and conductors, have negatively impacted and may again negatively impact our ability to meet short-term demand for rail service. Unpredicted increases in demand for rail services may exacerbate such risks and could negatively impact our operational efficiency.

Constraints on the supply chain or the operations of carriers with which we interchange may adversely affect our operations. Our ability to provide rail service to our customers depends in large part upon a functioning global supply chain and our ability to maintain collaborative relationships with connecting carriers (including shortlines and regional railroads) with respect to, among other matters, freight rates, revenue division, car supply and locomotive availability, data exchange and communications, reciprocal switching, interchange, and trackage rights. Deterioration in the supply chain or service provided by connecting carriers, or in our relationship with those connecting carriers, could result in our inability to meet our customers’ demands or require us to use alternate train routes, which could result in significant additional costs and network inefficiencies. Additionally, any significant consolidations, mergers, or operational changes among other railroads may alter our market access and reach.

We may be negatively affected by terrorism or war. Any terrorist attack, or other similar event, any government response thereto, and war or risk of war could cause significant business interruption or other operational challenges. Because we play a critical role in the nation’s transportation system, we could become the target of such an attack or have a significant role in the government’s preemptive approach or response to an attack or war.

Insurance coverage under Norfolk Southern's property and liability policies extends to certain acts of terrorism. In addition, premiums for some or all of our current insurance programs covering these losses could increase dramatically, or insurance coverage for certain losses could be unavailable to us in the future.

We may be negatively affected by supply constraints resulting from disruptions in our fuel markets or supplier markets. We consumed approximately 366 million gallons of diesel fuel in 2025. Fuel availability could be affected by limitation in the fuel supply or by imposition of mandatory allocation or rationing regulations. A severe fuel supply shortage arising from production curtailments, increased demand in existing or emerging foreign markets, disruption of oil imports, disruption of domestic refinery production, damage to refinery or pipeline infrastructure, political unrest, war, or other factors could impact us as well as our customers and other transportation companies.

Due to the capital-intensive nature, as well as the industry-specific requirements of the rail industry, high barriers of entry exist for potential new suppliers of core railroad items, such as locomotives and rolling stock equipment. As a result, we are dependent on certain key suppliers and manufacturers of locomotive and railroad items. Disruption to one or more of our key suppliers or manufacturers, including as a result of stopped or restricted production, labor stoppage or restriction, or significant supply shortage or outage could negatively impact our operating efficiency and increase costs. Additionally, we compete with other industries for available capacity and raw materials used in

the production of locomotives and certain track and rolling stock materials. Changes in the competitive landscapes of these limited supplier markets could also result in significantly increased prices or material shortages.

We may be negatively affected by energy prices. Fuel and energy costs have a significant impact on our operations. Volatility in energy prices could have a significant effect on a variety of items including, but not limited to: the economy; demand for transportation services; business related to the energy sector, including crude oil, natural gas, and coal; fuel prices; and, fuel surcharges, each of which could have a material impact on our business and results of operations. In addition, we may also experience a disruption in energy supplies as a result of new or increased regulation, as a result of war or geopolitical conflicts, weather-related events or natural disasters, or other factors beyond our control, which could have a material adverse effect on our business.

Pandemics, epidemics, or endemic diseases could further negatively impact us, our customers, our supply chain, and our operations. The magnitude and duration of a pandemic, epidemic, or endemic disease, and its impact on our customers and general economic conditions can influence the demand for our services and affect our revenues. In addition, such outbreaks could affect our operations and business continuity if a significant number of our essential employees, overall or in a key location, are unable to work from contraction of or exposure to the disease or if governmental orders prevent our employees or critical suppliers from working. To the extent such diseases adversely affect our business and financial results, they may also have the effect of heightening many of the other risks described in the risk factors included herein or may affect our operating and financial results in a manner that is not presently known to us.

Our business is capital intensive, and we must make capital decisions based upon expectations of future usage of our assets. We make significant investments in our railroad infrastructure, including railroad property, track infrastructure, locomotives, freight cars, intermodal equipment, technology, and other assets to support our network, much of which is costly and requires significant capital outlay. The amount and timing of capital investments depend on various factors, including expectations of future carload traffic. In many cases, we must make advance commitments to purchase or modify equipment prior to such equipment being needed. As a result, we must predict volume levels and other requirements and make commitments based on those projections. A significant variance in our expectations or projections could result in too much or too little equipment relative to our actual needs and volumes, thereby negatively impacting our operations or financial results.

TECHNOLOGY RISKS

A significant cybersecurity incident or other disruption to our technology infrastructure resulting from internal and external threats could disrupt our business operations. To conduct business, we extensively rely on information and operational technology systems. The threat landscape is vast, with potential attacks from cybercriminals, nation-states, state-sponsored actors and others including, but not limited to, service denials, unauthorized access, compromised equipment or rolling stock, extortion, or theft of data or money. As a result, our business continuity and disaster recovery plans and activities may not be sufficient for all eventualities, resulting in the potential for a data breach or significant service or operational disruption or failure involving one or more information or operational technology systems operated by us or under control of third parties, including computer hardware, software, cloud services and transportation and communications equipment. Such failures or disruptions can adversely impact our business by, among other things, preventing intercompany communications and disrupting operations that may result in direct or indirect monetary losses, damage to equipment or property, or loss of confidence in corporate competency. Any one or more of these events could have a material adverse effect on our results of operations, financial position, or operations. Although we maintain security programs designed to protect our information and operational technology systems, we are continually targeted by threat actors attempting to access our networks and we may be unable to detect or prevent a breach of our systems or equipment or disruption to our service in the future. In addition, while we have previously experienced technology outages and cybersecurity events that have impacted our systems and service, future events may result in more significant impacts to our operations, reputation or financial results. These potentially impactful future events could include service disruptions, unauthorized access to our systems or equipment, viruses, ransomware, and/or the compromise, acquisition, or destruction of our data. We also could be impacted by cybersecurity events targeting third parties

that we rely on for business operations, including third party vendors that have access to our systems or data and third parties who provide services and are in our supply chain. Such a direct or indirect cybersecurity incident could interrupt our service, cause safety failures or operational difficulties, decrease revenues, increase operating costs, impact our efficiency, damage our corporate reputation, and/or expose us to litigation or government action or increased regulation, which could result in penalties, fines or judgments. In addition, our failure to comply with or adhere to privacy-related or data protection laws and regulations could result in government investigations and proceedings against us, or litigation, resulting in adverse reputational impacts, penalties, and legal liability.

Our business may be seriously harmed if we fail to develop, implement, maintain, upgrade, enhance, protect and integrate our information or operational technology systems. If we fail to develop, acquire or implement new technology, or otherwise fail to maintain, protect or integrate our information or operational technology systems, we may suffer a competitive disadvantage within the rail industry and with companies providing alternative modes of transportation service. The techniques used by cybersecurity threat actors to obtain unauthorized access, disable or degrade service or sabotage systems change frequently, as data breaches and other cybersecurity events have become increasingly commonplace. Consequently, these techniques may be difficult to detect and cybersecurity events are therefore increasingly difficult to prevent. The rapid evolution and increased adoption of emerging technologies, such as artificial intelligence and machine learning (both of which we use), may make it more difficult to anticipate cybersecurity threats and implement adequate protective countermeasures. If we fail to adequately develop or maintain our information or operational technology systems or cybersecurity infrastructure, we may become increasingly vulnerable to cybersecurity events, or other breaches or disruptions to our information or operational technology systems.

LITIGATION RISKS

We may be subject to various claims and lawsuits that could result in significant expenditures. The nature of our business exposes us to the potential for various claims and litigation related to labor and employment, personal injury, commercial disputes, freight loss and other property damage, and other matters. Job-related personal injury and occupational claims are subject to the Federal Employer’s Liability Act (FELA), which is applicable only to railroads. FELA’s fault-based tort system produces results that are unpredictable and inconsistent as compared with a no-fault worker’s compensation system. The variability inherent in this system could result in actual costs being different from the liability recorded.

A catastrophic rail accident, whether on our lines or another carrier’s, involving any or all of release of hazardous materials, freight loss, property damage, personal injury, and environmental liability could compromise critical parts of our rail network. Losses associated with such an accident involving us could exceed our insurance coverage, resulting in a material adverse effect on our financial position or liquidity. Any material changes to current litigation trends could also have a material adverse effect on our financial position or liquidity to the extent not covered by insurance.

We have obtained insurance for potential losses for third-party liability and first-party property damages; however, insurance is available from a limited number of insurers and may not continue to be available or, if available, may not be obtainable on terms acceptable to us.

We are incurring significant expenditures as a result of claims and lawsuits arising from the Incident and the related Incident Proceedings, as described in “Incident Risks” above.

HUMAN CAPITAL RISKS

Failure to attract, retain, and transition key executive officers, or skilled professional or technical employees could adversely impact our business and operations. Our success depends on our ability to attract and retain skilled employees, including key executive officers to oversee our operational, productivity, marketing, and technological initiatives, as well as a sufficient number of skilled professional and craft employees to enable us to efficiently conduct our operations. Difficulties in recruiting and retaining skilled employees, including train and

engine workers, key executives, and other skilled professional and technical employees; the loss of such individuals; and/or our inability to successfully transition key executive, professional, technical, or skilled roles could each have a material adverse effect on our financial position, results of operations, and operations. The loss of one or more key employees could also result in the depletion of our institutional knowledge base and may result in our inability or increased difficulty in successfully transitioning key roles, which could materially adversely impact our business.

The vast majority of our employees belong to labor unions, and the renegotiation of labor agreements or any provisions thereof, or any strikes or work stoppages (including any entered into in connection with any such negotiations), could adversely affect our operations. Approximately 80% of our railroad employees are covered by collective bargaining agreements with various labor unions. Future national labor agreements, or renegotiation of labor agreements or provisions of labor agreements, could significantly increase our costs for health care, wages, and other benefits. In addition, if our craft employees were to engage in or threaten a strike, work stoppage, or other slowdown, including in connection with the renegotiation of any collective bargaining agreements or any provisions thereof, we could experience a significant disruption in our operations, customer base, or belief in our ability to provide consistent service, thereby adversely affecting our operations or ability to provide services.

CLIMATE CHANGE RISKS

Severe weather and disasters have caused, and could again cause, significant business interruptions and expenditures. Severe weather conditions and other natural phenomena resulting from changing weather patterns and rising sea levels or other causes, including hurricanes, floods, fires, landslides, extreme temperatures, significant precipitation, and earthquakes, have caused, and may again cause damage to our network, our workforce to be unavailable, and us to be unable to use our equipment, or otherwise cause significant interruptions to our operations. Additionally, shifts in weather patterns caused by climate change are expected to increase the frequency, severity, or duration of certain adverse weather conditions, which could cause more significant business interruptions that result in increased costs, increased liabilities, and decreased revenues. Our inability to quickly and effectively restore operations following adverse weather and disasters could materially impact our business and results of operations. To the extent such weather events or natural disasters become more frequent or severe, disruptions to our business and those of our customers and costs to repair damaged property and equipment or maintain or resume operations could increase. Furthermore, climate change may contribute to an increase in the incidence and severity of natural disasters and adverse weather conditions and reduce the availability or increase the cost of insurance for such events.

MACROECONOMIC AND MARKET RISKS

We may be negatively impacted by changes in general economic conditions. Because our business is dependent on the rail shipping needs of our customers, negative changes in domestic and global economic conditions, including reduced import and export volumes, could affect the producers and consumers of the freight we carry. Recessionary economic cycles and downturns in customers’ business cycles, especially in market segments and industries where we have a significant concentration of customers, may substantially reduce our volumes, and lead to excess capacity in the industry, resulting in pressure on rates we are able to obtain for our services. Economic conditions could also result in bankruptcies of one or more of our customers. Changes in general economic conditions are beyond our control, and it may be difficult for us to adjust our business model. We are impacted by industrial production, inflation, unemployment, and consumer spending. We have been and may in the future be, materially impacted by adverse developments in these aspects of the economy.

The state of capital markets could adversely affect our liquidity. We rely on the capital markets to provide some of our capital requirements, including the issuance of debt instruments and the sale of certain receivables. Significant instability or disruptions of the capital markets, including the credit markets, or deterioration of our financial position due to internal or external factors could restrict or eliminate our access to, and/or significantly increase the cost of, various financing sources, including bank credit facilities and issuance of corporate bonds. Instability or disruptions of the capital markets and deterioration of our financial position, alone or in combination, could also result in a reduction of our credit rating to below investment grade, which could prohibit or restrict us

from accessing external sources of short- and long-term debt financing and/or significantly increase the associated costs.

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 Coast and Great Lakes.

Throughout 2025, we took deliberate actions to strengthen the Company and position it for long-term success. 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. By integrating two complementary networks, the merged company will be positioned to deliver more efficient, reliable, and sustainable freight service across the nation. Details of the proposed transactions are further described in Note 2.

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. Safety continued to be a core value, and our relentless focus and intentional actions drove improvements in numerous safety metrics. Operational execution remained a key focus in 2025, with an emphasis on delivering high quality service while delivering notable improvements in labor productivity and fuel efficiency. Despite periods of macroeconomic uncertainty, growth in automotive and chemicals traffic, reflecting improved service and customer demand, drove merchandise revenues higher and led to a modest increase in overall volumes.

The combination of operational productivity, modest volume growth and favorable merchandise pricing were pivotal in driving earnings growth as compared to 2024. Although our financial results, as compared to the prior year, were significantly impacted by the absence of $433 million in gains on the sales of railway lines that occurred in 2024, we successfully monetized other properties that resulted in meaningful gains in the current year. For the full year, we achieved an operating ratio (a measure of the amount of operating revenues consumed by operating expenses) of 64.2%, and an adjusted operating ratio of 65.0% (see our non-GAAP reconciliations beginning on page K28). We remain committed to being a safe, productive, resilient, and efficient railroad with industry-competitive margins.

Railway operating ratio (percent)

Income from railway operations, net income, and diluted earnings per share increased in 2025 compared to 2024, the result of lower railway operating expense and higher railway operating revenues. The decrease in railway operating expense includes higher net recoveries related to the Incident in addition to lower expenses associated with restructuring activities. Partially offsetting those items were lower gains from the sales of railway lines and properties and expenses incurred in 2025 related to the proposed merger. The increase in railway operating revenues was driven by a combination of favorable traffic mix, which was partially offset by lower fuel surcharge revenue. Our railway operating ratio improved to 64.2 percent.

Income from railway operations, net income, and diluted earnings per share increased in 2024 compared to 2023, primarily a result of lower railway operating expenses. The reduction in our operating expenses included lower net expenses related to the 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.

The following tables adjust our 2025, 2024, and 2023 financial results as reported under U.S. Generally Accepted Accounting Principles (GAAP) financial results to exclude certain items. Adjusted 2025 financial results exclude Merger-related expenses, restructuring and other charges, and the overall impact on operating expenses resulting from costs and recoveries associated with the Incident. Adjusted 2024 financial results exclude gains on railway line sales, restructuring and other charges, costs and recoveries associated with the Incident, shareholder advisory costs, and a deferred tax adjustment. Adjusted 2023 financial results exclude the effects of the Incident. 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.

On an adjusted basis, income from railway operations in 2025 increased due to lower adjusted railway operating expenses and higher railway operating revenues, which drove improvements in net income, diluted earnings per share, and operating ratio. Railway operating revenues were higher driven by a combination of favorable traffic mix, which was partially offset by lower fuel surcharge revenue. Adjusted railway operating expenses were down over prior year as higher gains on operating property sales and lower fuel expense were partially offset by increased expenses associated with claims, materials, compensation and benefits, purchased services and equipment rents.

In 2024, on an adjusted basis, income from railway operations 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. Net income and diluted earnings per share were only up slightly compared to the prior year as lower other income-net and higher interest expense on debt offset the increase in income from railway operations.

Revenues increased $57 million in 2025 but decreased $33 million in 2024 compared to the prior year. Revenues increased in 2025 as a result of improved average revenue per unit, driven by favorable traffic mix being partially offset by lower fuel surcharge revenues, and increased volume. 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.

Total

Approximately 95% of our revenue base is covered by contracts that include negotiated fuel surcharges. Fuel surcharge revenues totaled $828 million, $962 million, and $1.2 billion in 2025, 2024, and 2023, respectively. The decline in fuel surcharge revenues in each comparison was primarily driven by fluctuations in fuel commodity prices.

MERCHANDISE revenues increased in both 2025 and 2024 compared with the prior years. In 2025, revenues increased as volume was higher and favorable pricing and mix more than offset lower fuel surcharge revenue. In 2024, revenues rose as volume was higher for all commodity groups and pricing gains more than offset lower fuel surcharge revenue.

Agriculture, forest and consumer products revenues increased in 2025 but decreased slightly in 2024 compared with the prior years. In 2025, the increase in revenues was the result of higher average revenue per unit due to favorable pricing and mix, offset partially by lower fuel surcharge revenue. Volume declined from the prior year, primarily related to corn and soybean shipments. Decreased corn volumes were the result of decreased demand for shipments to the southeast. Soybean volumes decreased due to lower export demand. 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.

Chemicals revenues increased in both 2025 and 2024 compared with the prior years. In 2025, the increase in revenues was driven by volume increases, partially offset by lower average revenue per unit due to adverse mix and lower fuel surcharge revenues. Natural gas liquids volume rose due to an increased demand for product bound for export markets. Sand volumes increased due to strong demand to support natural gas drilling. 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.

Metals and construction revenues were higher in both 2025 and 2024 compared with the prior years. In 2025, the increase was driven by higher average revenue per unit due to favorable price and mix, partially offset by lower fuel surcharge revenue, with volumes down slightly. Increases in iron, steel, and scrap volume due to stronger demand were offset by weather-related impacts that negatively impacted shipments of aggregates. 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.

Automotive revenues rose in both 2025 and 2024 compared with the prior years. The increase in revenues in 2025 was driven by higher volume. Volume increases were driven by shippers increasing volume in response to tariff changes, growth with existing customers, and the absence of customer production issues experienced in the prior year. 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.

INTERMODAL revenues decreased in both 2025 and 2024 compared with the prior years. The decrease in 2025 was the result of lower volumes, and, to a lesser extent, distribution network diversification by certain of our customers in connection with the Merger. Average revenue per unit was up slightly compared to 2024 with increased pricing being offset by lower fuel surcharge revenue and adverse mix. 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.

Intermodal units by market were as follows:

(units in thousands)

(% change)

Domestic

International

Total

Domestic volume decreased in 2025 but increased in 2024 compared with the prior years. In 2025, volume decreased due to reduced traffic originating on the West Coast, increased market competition, and reduced demand for premium shipments. In 2024, volume increased due to growth in new and existing customers and improved service, partially offset by reduced demand for premium shipments.

International volume was flat in 2025 and increased in 2024. Volume in 2025 was impacted by increased demand in the first half of the year in response to tariffs and growth with key customers, which was offset by lower imports and business losses in the second half of the year. The increase in 2024 was driven by increased demand, growth with existing customers, and increased movements of empty containers.

COAL revenues decreased in both 2025 and 2024 compared with the prior years. The decrease in 2025 was a result of lower average revenue per unit, driven by decreased pricing, adverse mix, and lower fuel surcharge revenue, partially offset by increased volume. 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.

As shown in the following table, total tonnage increased in 2025 and 2024 compared to prior years.

Total

Utility coal tonnage increased in 2025 but decreased in 2024 compared with the prior years. The increase in 2025 was due to higher electricity demand and higher natural gas prices. The decline in 2024 was due to reduced demand from continued low natural gas prices and high stockpiles.

Export coal tonnage declined in 2025 but increased in 2024 compared with the prior years. The decrease in 2025 was due to soft global demand and unfavorable seaborne coal pricing. The increase in 2024 was due to growth with our customers and increased production.

Domestic metallurgical coal tonnage decreased in both 2025 and 2024 compared with the prior years. The decrease in 2025 was due to a soft domestic market that resulted in idled facilities due to reduced customer demand. The decrease in 2024 was as a result of reduced customer demand.

Industrial coal tonnage increased in both 2025 and 2024 compared with the prior years. The growth in both years was due to higher demand.

In 2025, the decline in railway operating expenses reflects net recoveries related to the Incident (Note 19) and lower restructuring charges (Note 4), which were partially offset by lower gains from the sales of railway lines and properties (Note 9) and the incurrence of merger-related expenses (Note 2). In 2024, the decline in railway operating expenses reflects lower net expenses related to the Incident (Note 19), higher gains on operating property sales, including certain gains on railway line sales (Note 9), and lower fuel prices, partially offset by restructuring and other charges (Note 4), and increased depreciation on our higher asset base.

Compensation and benefits increased in 2025, reflecting changes in:

• incentive and stock-based compensation (up $154 million),

• pay rates (up $81 million),

• health and welfare benefits (down $41 million),

• employee activity levels (down $75 million), and

• other (down $20 million).

In 2024, compensation and benefits increased, a result of 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).

Our employment averaged 19,400 in 2025, compared with 20,200 in 2024, and 20,300 in 2023.

Purchased services includes the costs of services purchased from external vendors and contractors, including the net costs of operating joint facilities with other railroads. Purchased services increased in 2025 primarily due to higher response costs associated with weather events, higher derailment-related expenses (unrelated to the Incident), and increased intermodal lift costs. 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.

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 2025, the increase was due to increased automotive equipment expense resulting from higher volumes. In 2024, the increase was due to increased automotive and intermodal equipment expenses as a result of higher volumes.

Fuel expense, which includes the cost of locomotive fuel as well as other fuel used in railway operations, decreased in both 2025 and 2024. The decrease in both periods was due to lower locomotive fuel prices (down 4% in 2025 and 15% in 2024), which decreased fuel expense by $35 million and $159 million in 2025 and 2024, respectively. Locomotive fuel consumption was down in 2025 and 2024 compared to prior periods. We consumed 366 million gallons of diesel fuel in 2025, compared with 373 million gallons in 2024 and 377 million gallons in 2023.

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 2025 and 2024. The increase in 2025 was partly due to higher locomotive and freight car material consumption coupled with increased spend for other materials. The increase in 2024 was due to higher freight car repairs expense, partially offset by lower locomotive materials spending.

Claims expense includes costs related to personal injury, property damage, and environmental matters. Claims expense increased in 2025 but decreased in 2024 compared to the prior years. The increase in 2025 is the result of higher personal injury case development, increased expenses associated with environmental matters unrelated to the Incident, and higher insurance premiums. 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.

Other expense increased in 2025, primarily due to the absence of $433 million in gains from the sale of railway lines in the states of Virginia and North Carolina in 2024, but partially offset by gains on the sales of other operating properties and insurance proceeds pertaining to damages resulting from Hurricane Helene. Gains from operating property sales, inclusive of the railway line sales, amounted to $253 million, $490 million, and $43 million in 2025, 2024, and 2023, respectively. Other expense decreased in 2024 due to the aforementioned $433 million gains on railway line sales, as further described in Note 9, but also from lower non-income-based taxes as well as relocation and travel-related expenses.

Merger-related expenses in 2025 were $80 million and primarily relate to costs associated with employee retention agreements, third-party advisor fees, and legal fees.

Restructuring and other charges in 2025 totaled $22 million and includes expenses associated with the restructuring of certain technology functions, including severance costs for impacted employees, and the rationalization of certain software development projects that had not been placed into service. Restructuring and other charges totaled $183 million in 2024 and includes expenses associated with our voluntary and involuntary separation programs that reduced our management workforce, expenses associated with the rationalization of certain software development projects that had not been placed into service, costs associated with the appointment of our new chief operating officer, and the disposition of an asset class. See Notes 4 and 14 for additional information.

Eastern Ohio incident activity during 2025 reflected insurance and other recoveries that exceeded additional Incident-related expenses by $254 million. Insurance and other recoveries total $418 million in 2025. 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. In 2025, net cash inflows attributable to the Incident were $249 million driven by insurance and other recoveries, while 2024 resulted in cash expenditures, net of insurance proceeds, of $119 million. The overall net cash impact attributable to the Incident is presented in “Net cash provided by operating activities” on the Consolidated Statements of Cash Flows. For further details regarding the Incident, see Note 19.

Other Income – Net

Other income – net increased in 2025 but decreased in 2024. The increase in 2025 reflects the absence of prior year shareholder advisory costs partially offset by the absence of a prior year curtailment gain and lower net pension and other postretirement benefits in the current year. 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 (Notes 4 and 14).

Income Taxes

The effective income tax rate was 21.6% in 2025, compared with 21.2% in 2024 and 21.3% in 2023. The rate for 2025 is higher than the previous year, mainly driven by state tax mix and other smaller items. While we recorded a $50 million state-related discrete tax item in 2025, other discrete benefits in 2024 did not recur. We recorded 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 in 2024. The 2023 effective rate benefited from tax credits and higher COLI returns offset by reduced benefits from stock-based compensation.

On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was signed into law. The OBBBA makes permanent or introduces certain changes to the Internal Revenue Code, including 100% bonus depreciation, the deductibility of business interest expense, and expensing of domestic research costs. Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 740 “ Income Taxes ” requires that the effect of changes in tax rates and laws be recognized in the period in which the legislation is enacted. The impact of this change is primarily a reclassification from current to deferred taxes.

For 2026, 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 $4.4 billion in 2025, $4.1 billion in 2024, and $3.2 billion in 2023. The increases in 2025 and 2024 reflect improved operating results. We had negative working capital of $577 million at December 31, 2025 and $357 million at December 31, 2024. Cash and cash equivalents totaled $1.5 billion and $1.6 billion at December 31, 2025, and 2024, respectively. 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, subject to certain restrictions on incurring additional indebtedness under the Merger Agreement.

Contractual obligations at December 31, 2025, including those that may have material cash requirements, include interest on fixed-rate long-term debt, long-term debt (Note 11), unconditional purchase obligations (Note 19), long-term advances from Conrail Inc. (Conrail) (Note 8), operating leases (Note 12), agreements with Consolidated Rail Corporation (CRC) (Note 8), and unrecognized tax benefits (Note 6).

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.

Cash used in investing activities was $2.6 billion in 2025, $2.8 billion in 2024, and $2.2 billion in 2023. The decrease in 2025 was driven by the prior year acquisition of the assets of the Cincinnati Southern Railway (CSR) and lower property additions in the current year, which was partially offset by the current year repayment of borrowings against our COLI policies that occurred in the prior year and lower proceeds from property sales and other transactions. In 2024, the increase 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 9 for additional details on certain railway line sales and a discussion of the acquisition of the CSR assets.

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 2026, we expect property additions to approximate $1.9 billion.

Cash used in financing activities was $1.9 billion in 2025 and $1.2 billion in 2024, while cash provided by financing activities was $115 million in 2023. The increase in cash used in financing activities in 2025 reflects increased repurchases of Common Stock and lower proceeds from borrowing, partially offset by lower debt repayments. In 2024, the increase in cash used in financing activities reflects lower proceeds from borrowing partially offset by the absence of repurchases of Common Stock.

In 2025, we repurchased and retired $534 million of Common Stock, inclusive of paid excise taxes, which resulted in the retirement of 2.2 million shares. While we did not repurchase any Common Stock in 2024, we repurchased and retired $622 million in 2023, which resulted in the retirement of 2.8 million shares. As of December 31, 2025, $6.3 billion remains authorized by our Board of Directors for repurchase. With limited exceptions, the Merger Agreement prohibits the Company from repurchasing shares of its Common Stock without approval by Union Pacific. As a result, the Company has suspended share repurchase activities.

In May 2025, we issued $400 million of 5.10% senior notes due 2035.

In May 2025, 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 2026. We had no amounts outstanding under this program and our available borrowing capacity was approximately $397 million and $400 million at December 31, 2025 and December 31, 2024, respectively.

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 both December 31, 2025 and December 31, 2024, we had no outstanding commercial paper.

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, 2025 or December 31, 2024, and we are in compliance with all of its covenants.

In addition, we have investments in general purpose COLI policies and had the ability to borrow against these policies. We had no amounts borrowed against these policies at December 31, 2025 and $605 million borrowed against these policies on December 31, 2024. Our remaining borrowing capacity was $595 million and $40 million at December 31, 2025 and December 31, 2024, respectively.

Our debt-to-total capitalization ratio was 52.4% at December 31, 2025, compared with 54.6% at December 31, 2024. We discuss our credit agreement and our accounts receivable securitization program in Note 11. Upcoming annual debt maturities are also disclosed in Note 11. 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 ongoing environmental monitoring 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 the long-term monitoring activities that are currently anticipated and governmental oversight and other costs, amongst other factors. Estimates associated with the legal proceedings to 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 the long-term monitoring liabilities related to the Incident may change over time due to various factors, including but not limited to, results from monitoring activities and the extent 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. We have now completed recoveries under our liability insurance policies. Any additional amounts that are recoverable under other insurance policies or from third parties will be reflected in the period in which recovery is considered probable.

See Note 19 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 14). 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 2025, 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 $26 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 $15 million increase in annual pension expense.

Properties and Depreciation

Most of our assets are long-lived railway properties (Note 9). “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 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 2025 totaled $1.4 billion. Our composite depreciation rates for 2025 are disclosed in Note 9; a one-year increase (or decrease) in the estimated average useful lives of depreciable assets would have resulted in an approximate $49 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 19 for a more detailed discussion of the assumptions and estimates we use for personal injury.

Income Taxes

Our net deferred tax liability totaled $7.7 billion at December 31, 2025 (Note 6). 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 $45 million valuation allowance on $412 million of deferred tax assets as of December 31, 2025, 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 moratorium provisions from the last round of negotiations, neither party was permitted to serve notice to compel a new round of mandatory collective bargaining until November 1, 2024. Since that date, Norfolk Southern, or the NCCC acting on behalf of Norfolk Southern, has engaged in discussions and reached ratified agreements with all of our labor unions.

Moratorium clauses in these new ratified agreements foreclose the parties from serving further notices to compel mandatory bargaining until November 1, 2029. During this period, self-help against Norfolk Southern (e.g., a strike or other work stoppage) related to the mandatory collective-bargaining process is prohibited by law.

Market Risks

We manage overall exposure to fluctuations in interest rates by issuing both fixed- and floating- rate debt instruments. At December 31, 2025, 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, 2025 and amounts to an increase of approximately $1.5 billion to the fair value of our debt at December 31, 2025. 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

Certain statements in this report, including in Management’s Discussion and Analysis of Financial Condition and Results of Operations, are “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, as amended. These statements relate to future events or our future financial performance and involve known and unknown risks, uncertainties, and other factors that may cause our actual results, levels of activity, performance, or our achievements or those of our industry to be materially different from those expressed or implied by any forward-looking statements.

We have based these forward-looking statements on our current expectations, assumptions, estimates, beliefs, and projections. While we believe these expectations, assumptions, estimates, beliefs, and projections are reasonable, such forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which involve factors or circumstances that are beyond our control. The following important factors, including those discussed in Item 1A “Risk Factors,” may cause actual results, performance, or achievements to differ materially from those expressed or implied by these forward-looking statements:

• changes in domestic or international economic, political or business conditions, including those impacting the transportation industry;

• our ability to successfully implement our operational, productivity, and strategic initiatives;

• a significant adverse event on our network, including but not limited to a mainline accident, discharge of hazardous material, or climate-related or other network outage;

• the outcome of claims, litigation, governmental proceedings, and investigations involving the Company, including but not limited to the Incident Proceedings;

• new or additional governmental regulation and/or operational changes resulting from or related to the Incident or the Incident Proceedings;

• a significant cybersecurity incident or other disruption to our technology infrastructure;

• our ability to complete the Mergers with Union Pacific;

• the occurrence of any event, change or other circumstance that could give rise to the right of one or both of the Company or Union Pacific to terminate the Merger Agreement;

• the possibility that the Mergers do not close when expected or at all because required Surface Transportation Board review and approval, or other approvals and other conditions to close are not received or satisfied on a timely basis or at all (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the Mergers);

• the risk that the combined company will not realize expected benefits, cost savings, accretion, synergies and/or growth from the Mergers, or that such benefits may take longer to realize or be more costly to achieve than expected;

• disruption to the Company's business as a result of the announcement and pendency of the Mergers, including the restrictions contained in the Merger Agreement on the ability of the Company to operate its business outside the ordinary course during the pendency of the Mergers;

• the diversion of the Company's management's attention and time from ongoing business operations and opportunities on Merger-related items;

• the possibility that the Mergers may be more expensive to complete than anticipated, including as a result of unexpected factors or events; and

• the reputational risk and adverse reactions of customers (certain of whom have and may continue to diversify their distribution networks, including in response to actions by our competitors), suppliers,

employees, labor unions or other business partners, including those resulting from the announcement or completion of the Mergers.

The forward-looking statements herein are made only as of the date they were first issued, and unless otherwise required by applicable securities laws, we disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.
