RISKS RELATED TO THE MERGERS

Current report

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.

Current report

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.

Current report

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:

Current report

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

Current report

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

Current report

•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;

Current report

•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;

Current report

•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

Current report

•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.

Current report

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.

Current report

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.

Current report

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 ma…

Excerpt shortened here; the source contains the full paragraph.

Current report

K12 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.

Current report

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.

Current report

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.

Current report

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.

Current report

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.

Current report

Each of the risks described above may be exacerbated by delays or other adverse developments with respect to the completion of the Mergers.
Removed paragraphs (5)

Previous report

As noted in “Incident Risks” above, in connection with the Incident, we are experiencing negative impacts related to environmental matters, including extensive cleanup costs and litigation related to alleged environmental impacts of the Incident.

Previous report

Concern over climate change has led to significant federal, state, and international legislative and regulatory efforts to limit greenhouse gas (GHG) emissions. Restrictions, caps, taxes, or other legislative or regulatory controls on GHG emissions, including diesel exhaust, could significantly increase our operating costs and decrease the amount of traffic we handle.

Previous report

In addition, legislation and regulation related to climate change or GHG emissions could negatively affect the markets we serve and our customers. Even without legislation or regulation, government incentives and adverse publicity relating to climate change or GHG emissions could negatively affect the markets for certain of the commodities we carry, or our customers that use commodities we carry to produce energy (including coal), use significant amounts of energy in producing or delivering the commodities we carry, or manufacture or produce goods that consume significant amounts of energy associated with GHG emissions.

Previous wording

As defined and as further described in Note 18 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 18 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.

Previous wording

The STB also has jurisdiction over the consolidation, merger, or acquisition of control of and by rail common carriers. Additional or updated regulation of the rail industry by Congress or the STB, whether under new, existing or amended laws or regulations, 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.

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.

Previous wording

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.

Previous wording

Although we currently maintain insurance coverage for third-party liability arising out of war and acts of terrorism, we maintain only limited insurance coverage for first-party property damage and damage to property in our care, custody, or control caused by 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.

Current wording

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.

Previous wording

We may be negatively affected by supply constraints resulting from disruptions in our fuel markets or supplier markets. We consumed approximately 373 million gallons of diesel fuel in 2024. 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.

Current wording

Previous wording

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

Previous wording

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 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, viruses, ransomware, and/or the compromise, acquisition, or destruction of our

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, 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.

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. In the third and fourth quarters of 2024, the Company reached tentative collective bargaining agreements with ten of these labor unions, a majority of which were subsequently ratified by union membership and became effective January 1, 2025. 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.

Previous wording

K18 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.
