Pending acquisition risks

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 our business —On July 28, 2025, the Company, Norfolk Southern, Ruby Merger Sub 1 Corporation, and Ruby Merger Sub 2 LLC, entered into an agreement and plan of merger (the merger agreement). The completion of the mergers (as defined in the merger agreement) 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 the Company or Norfolk Southern may terminate the merger agreement if the mergers have not been consummated by January 28, 2028, which is referred to as 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, our ongoing business may be materially adversely affected and, without realizing any of the benefits of having completed the mergers, we will be subject to a number of risks, including the following:

Current report

•we could owe substantial termination fees to Norfolk Southern under certain circumstances;

Current report

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

Current report

•we may experience negative reactions from the financial markets or from customers, suppliers, employees, labor unions, or other business partners; and

Current report

•we will be required to pay our respective costs relating to the mergers, such as legal, accounting, and printing fees, whether or not the mergers are completed.

Current report

In addition, if the mergers are not completed, we could be subject to litigation related to any failure to complete the mergers or related to any enforcement proceeding commenced against us to perform our 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 our ongoing business.

Current report

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

Current report

The merger agreement contains provisions that limit our ability to pursue alternatives to the mergers, and, in specified circumstances, could require us to pay substantial termination fees to Norfolk Southern —The merger agreement contains certain provisions that restrict our ability to initiate, solicit, knowingly encourage, or, subject to certain exceptions, engage in discussions or negotiations with respect to, or approve or recommend, any alternative proposal.

Current report

In some circumstances, upon termination of the merger agreement in connection with an alternative proposal, we may be required to pay a termination fee of $2.5 billion to Norfolk Southern.

Current report

These provisions could discourage a potential acquiror of us or alternative merger partner that might have an interest in acquiring all or a significant portion of the Company or pursuing an alternative acquisition transaction with us from considering or proposing such a transaction, even if it were prepared to pay consideration with a higher per-share value than the per-share value proposed to be realized in the mergers. In particular, a termination fee, if applicable, could result in a potential acquiror of us or alternative merger partner proposing to pay a lower price to our shareholders than it might otherwise have proposed to pay absent such a fee.

Current report

If the merger agreement is terminated in accordance with its terms, and we or Norfolk Southern seek another business combination, we may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the merger agreement.

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, Norfolk Southern, 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 the approval, authorization, or exemption by the U.S. Surface Transportation Board (STB) of the mergers and other transactions contemplated by the merger agreement within the jurisdiction of 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, the Company and Norfolk Southern 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 we are not required to take, or commit to take, or agree to or accept any “materially burdensome regulatory condition” (as defined in the merger agreement). 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 the Company or of Norfolk Southern and its subsidiaries and (ii) otherwise taking or committing to take any actions that after the first effective time (as defined in the merger agreement) would limit our freedom of action with respect to, or our ability to retain, or otherwise agreeing to any restriction, requirement, or limitation with respect to our 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, the Company and Norfolk Southern. Su…

Excerpt shortened here; the source contains the full paragraph.

Current report

In addition, under existing law, our railroad competitors and customers, Norfolk Southern’s railroad competitors and customers, 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 the Company and Norfolk Southern 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 and Norfolk Southern are each subject to business uncertainties and contractual restrictions while the mergers are pending, which could adversely affect both our business and operations and the combined company’s business and operations —In connection with the pendency of the mergers, some customers, suppliers, and other persons with whom the Company or Norfolk Southern has a business relationship have or may delay or defer certain business decisions or terminate, change, or renegotiate their relationships with us or Norfolk Southern, as the case may be, as a result of the mergers, which could negatively affect our or Norfolk Southern’s respective revenues, earnings, and cash flows, as well as the market price of our common stock, regardless of whether the mergers are completed.

Current report

Under the terms of the merger agreement, each of the Company and Norfolk Southern is subject to certain restrictions on the conduct of its business prior to completing the first merger (as defined in the merger agreement), which may adversely affect its ability to execute certain of its business strategies, including, in the case of Norfolk Southern, 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 each party’s businesses and operations prior to the completion of the mergers.

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.

Current report

Uncertainties associated with the mergers may cause a loss of management personnel and other key employees, and the Company and Norfolk Southern may have difficulty attracting and motivating management personnel and other key employees, and combining cultures between the two companies could be challenging, which could adversely affect the future business and operations of the combined company —The Company and Norfolk Southern are dependent on the experience and industry knowledge of their respective management personnel and other key employees to execute their business plans. The combined company’s success after the completion of the mergers will depend in part upon our ability, and Norfolk Southern’s ability, to attract, motivate, and retain key management personnel and other key employees as well as develop a singular culture framed in the strategy of Safety, Service, and Operational Excellence. Prior to completion of the mergers, our current and prospective employees, and Norfolk Southern’s current and prospective employees, may experience uncertainty about their roles within the combined company following the completion of the mergers, which may have an adverse effect on our ability, and Norfolk Southern’s ability, to attract, motivate, or retain management personnel and other key employees. In addition, no assurance can be given that the combined company will be able to attract, motivate, or retain management personnel and other key employees of the Company and Norfolk Southern to the same extent that the Company and Norfolk Southern have previously been able to attract or retain employees.

Current report

We may and have been a target of securities class action and derivative lawsuits that could result in substantial costs and may delay or prevent the mergers from being completed, whether or not such lawsuits have any merit —Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into merger agreements. Even if the lawsuits are without merit, defending against or otherwise resolving these claims can result in substantial costs and divert management time and resources. An adverse judgment could result in monetary damages, which could have a negative impact on our liquidity and financial condition. Additionally, if a plaintiff is successful in obtaining an injunction prohibiting completion of the mergers, then that injunction may delay or prevent the mergers from being completed, or from being completed within the expected timeframe, which may adversely affect our business, financial position, and results of operation.

Current report

Completion of the mergers may trigger change in control or other provisions in certain agreements to which Norfolk Southern or its subsidiaries are a party, which may have an adverse impact on the combined company’s business and results of operations —The completion of the mergers may trigger change in control and other provisions in certain agreements to which Norfolk Southern or its subsidiaries are a party. If the Company and Norfolk Southern are unable to negotiate waivers of those provisions, the counterparties may exercise their rights and remedies under the agreements, potentially terminating the agreements or seeking monetary damages. Even if the Company and Norfolk Southern are able to negotiate waivers, the counterparties may require a fee for such waivers or seek to renegotiate the agreements on terms less favorable to Norfolk Southern or the combined company. Any of the foregoing or similar developments may have an adverse impact on the combined company’s business and results of operations.

Current report

The combined company may be unable to successfully integrate the businesses of the Company and Norfolk Southern and realize the anticipated benefits of the mergers —The success of the mergers will depend, in part, on the combined company’s ability to successfully combine the businesses of the Company and Norfolk Southern, which currently operate as independent public companies, and realize the anticipated benefits, including synergies, cost savings, innovation, and operational efficiencies, from the combination. If the combined company is unable to achieve these objectives within the anticipated time frame, or at all, the anticipated benefits may not be realized fully, or at all, or may take longer to realize than expected and the value of its common stock may be harmed. Additionally, as a result of the mergers, rating agencies may take negative actions against the combined company’s credit ratings, which may increase the combined company’s financing costs, including in connection with any financing of the mergers.

Current report

The mergers involve the integration of Norfolk Southern’s business with our existing business, which is a complex, costly, and time-consuming process. Neither the Company nor Norfolk Southern have previously completed a transaction comparable in size or scope to the mergers. The integration of the two (2) companies may result in material challenges, including, without limitation:

Current report

•the diversion of management’s attention from ongoing business concerns and performance shortfalls at one or both of the companies as a result of the devotion of management’s attention to the mergers;

Current report

•managing a larger combined company;

Current report

•creating, implementing, and executing a unified business strategy, and operational, financial, and managerial control with respect to the combined entity;

Current report

•the inherent risk and complexity of integrating railroad operations, including operating, information technology, safety, and managerial systems and processes, particularly on a large scale, in the context of ongoing business operations and customer commitments;

Current report

•maintaining employee morale and attracting, motivating, and retaining management personnel and other key employees;

Current report

•the possibility of faulty assumptions underlying expectations regarding the integration process;

Current report

•retaining existing business and operational relationships and attracting new business and operational relationships;

Current report

•consolidating corporate and administrative infrastructures and eliminating duplicative operations and inconsistencies in standards, controls, procedures, and policies;

Current report

•coordinating geographically separate organizations;

Current report

•unanticipated changes in federal or state laws or regulations or international trade agreements, including additional regulatory scrutiny or additional regulatory requirements as a result of the transaction or the size, scope, and complexity of the combined company’s business operations; and

Current report

•unforeseen expenses or delays associated with the mergers.

Current report

Many of these factors will be outside of the combined company’s control and any one of them could result in delays, increased costs, decreases in the amount of expected revenues, and diversion of management’s time and energy, which could materially affect the combined company’s financial position, results of operations, and cash flows.

Current report

The Company and Norfolk Southern have operated, and until completion of the mergers will continue to operate, independently. The Company and Norfolk Southern are currently permitted to conduct only limited planning for the integration of the two (2) companies following the mergers and have not yet determined the exact nature of how the businesses and operations of the two (2) companies will be combined after the mergers. The actual integration may result in additional and unforeseen expenses, and the anticipated benefits of the integration plan may not be realized.

Current report

The future results of the combined company may be adversely impacted if the combined company does not effectively manage its expanded operations following the completion of the mergers —Following the completion of the mergers, the size of the combined company’s business will be significantly larger than the current size of our business. The combined company’s ability to successfully manage this expanded business will depend, in part, upon management’s ability to design and implement operational, managerial, financial, and strategic initiatives that address not only the integration of two (2) independent stand-alone companies, but also the increased scale and scope of the combined business with its associated increased costs and complexity. There can be no assurances that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings, and other benefits currently anticipated from the mergers.

Current report

The combined company is expected to incur substantial expenses related to the completion of the mergers and the integration of the Company and Norfolk Southern —The combined company is expected to incur substantial expenses in connection with the completion of the mergers and the integration of the Company and Norfolk Southern. There are a large number of processes, policies, procedures, operations, technologies, and systems that must be integrated, including purchasing, accounting and finance, sales, payroll, pricing, revenue management, marketing, and benefits. In addition, our business and Norfolk Southern’s business will continue to maintain a presence in Omaha, Nebraska and Atlanta, Georgia, respectively. The substantial majority of these costs will be non-recurring expenses related to the mergers (including any financing of the mergers), facilities, and systems consolidation costs. The combined company may incur additional costs to retain employees and/or maintain employee morale and to attract, motivate, or retain management personnel and other key employees. We will also incur transaction fees and costs related to formulating integration plans for the combined business, and the execution of these plans may lead to additional unanticipated costs. Additionally, as a result of the mergers, rating agencies may take negative actions with regard to the combined company’s credit ratings, which may increase the combined company’s financing costs, including in connection with any financing of the mergers. These incremental transaction and merger-related costs may exceed the savings the combined company expects to achieve from the elimination of duplicative costs and the realization of other efficiencies related to the integration of the businesses, particularly in the near term, and in the event there are material unanticipated costs.

Current report

The combined company’s indebtedness may limit its flexibility and increase its borrowing costs —The combined company’s consolidated indebtedness may have the effect of, among other things, increasing borrowing costs. In addition, the amount of cash required to service the indebtedness levels will be greater than the amount of cash flows required to service the indebtedness of the Company or Norfolk Southern individually prior to completion of the mergers. The level of indebtedness could also reduce dividend payments, share repurchases, and other activities and may create competitive disadvantages relative to other companies with lower debt levels. The combined company may be required to raise additional financing for working capital, capital expenditures, acquisitions, or other general corporate purposes. The combined company’s ability to arrange additional financing or refinancing will depend on, among other factors, its financial condition and performance, as well as prevailing market conditions, the terms of third party debt financing incurred in connection with the consummation of the mergers (if any), and other factors beyond its control. There can be no assurance that the combined company will be able to obtain additional financing or arrange refinancing on terms acceptable to it or at all, and any such failure could materially adversely affect its operations and financial condition.

Current report

The financing arrangements that the combined company will enter into in connection with the mergers may, under certain circumstances, contain restrictions and limitations that could significantly impact the combined company’s ability to operate its business —We expect to incur significant new indebtedness in connection with the mergers. We also expect that the agreements governing the indebtedness that the combined company will incur in connection with the mergers will contain covenants that, among other things, may, under certain circumstances, place limitations on the dollar amounts paid or other actions we or the combined company can or will be able to take.

Previous wording

We Rely on Technology and Technology Improvements in Our Business Operations – We rely on information technology in all aspects of our business, including technology systems operated by us (whether created by us or purchased), under control of third parties, and open-source software. If we do not have sufficient capital or do not deploy sufficient capital in a timely manner to acquire, develop, or implement new technology or maintain or upgrade current systems, such as Positive Train Control (PTC) or the latest version of our transportation control systems, we may suffer a rail service outage or competitive disadvantage within the rail industry and with companies providing other modes of transportation service, which could have a material adverse effect on our results of operations, financial condition, and liquidity.

Current wording

The ability to update or maintain technology could adversely affect our operations – We rely on information technology in all aspects of our business, including technology systems operated by us (whether created by us or purchased), under control of third parties, and open-source software. If we do not have sufficient capital or do not deploy sufficient capital in a timely manner to acquire, develop, or implement new technology or maintain or upgrade current systems, such as Positive Train Control (PTC), NetControl, or the latest version of our transportation control systems, we may suffer a rail service outage or competitive disadvantage within the rail industry and with companies providing other modes of transportation service, which could have a material adverse effect on our results of operations, financial condition, and liquidity.

Previous wording

A Significant Portion of Our Revenues Involves Transportation of Commodities to and from International Markets – Although revenues from our operations are attributable to transportation services provided in the U.S., a significant portion of our revenues involves the transportation of commodities to and from international markets, including Mexico, Canada, and Southeast Asia, by various carriers and, at times, various modes of transportation. Significant and sustained interruptions of trade with Mexico, Canada, or countries in Southeast Asia, including China, could adversely affect customers and other entities that, directly or indirectly, purchase or rely on rail transportation services in the U.S. as part of their operations, and any such interruptions, including international armed conflicts such as the Russia-Ukraine and Israel-Hamas wars, could have a material adverse effect on our results of operations, financial condition, and liquidity. Any one or more of the following could cause a significant and sustained interruption of trade with Mexico, Canada, or countries in Southeast Asia: (a) a deterioration of security for international trade and businesses; (b) the adverse impact of new laws, rules, and regulations or the interpretation or enforcement of laws, rules, and regulations by government entities, courts, or regulatory bodies, including the United States-Mexico-Canada Agreement (USMCA) or other international trade agreements; (c) actions of taxing authorities that affect our customers doing business in or with foreign countries; (d) any significant adverse economic developments, such as extended periods of high inflation, material disruptions in the banking sector or in the capital markets of these foreign countries, and significant changes in the valuation of the currencies of these foreign countries that could materially affect the cost or value of imports or exports; (e) shifts in patterns of international trade, including as a result of changes to international trade agreements or policies, that adversely affect import and export markets; (f) a material reduction in foreign direct investment in these countries; and (g) public health crises, including the outbreak of pandemic or contagious disease, such as the coronavirus and its variant strains (COVID). An imposition of tariffs on imports or other changes to U.S. trade policy could cause demand for shipping from international markets to decrease, and if the declines are significant enough, it could have a material adverse effect on our results of operations, financial condition, and liquidity.

Changes to trade policy both U.S. and foreign, including imposition of tariffs on imports, could cause demand for shipping from international markets to decrease, and if the declines are significant enough, it could have a material adverse effect on our results of operations, financial condition, and liquidity.

We Are Dependent on Certain Key Suppliers of Locomotives and Rail– Due to the capital-intensive nature and sophistication of locomotive equipment, parts, and maintenance, potential new suppliers face high barriers to entry. Therefore, if one of the domestic suppliers of locomotives discontinues manufacturing locomotives, supplying parts, or providing maintenance for any reason, including bankruptcy or insolvency or the inability to manufacture locomotives that meet efficiency or regulatory emissions standards, we could experience significant cost increases and reduced availability of the locomotives that are necessary for our operations. Additionally, we utilize a limited number of steel producers that meet our specifications. Rail is critical to our operations for rail replacement programs, maintenance, and for adding additional network capacity, new rail and storage yards, and expansions of existing facilities. This industry similarly has high barriers to entry, and if there isany significant consolidations or mergers in this industry, orone of these suppliers discontinues operations for any reason, including bankruptcy or insolvency, we could experience both significant cost increases for rail purchases and difficulty obtaining sufficient rail for maintenance and other projects. Changes to trade agreements or policies that result in increased tariffs on goods imported into the United States could also result in significant cost increases for rail purchases and difficulty obtaining sufficient rail.

Previous wording

We Are Subject to Significant Governmental Regulation – We are subject to governmental regulation by a significant number of federal, state, and local authorities covering a variety of health, safety, labor, employment, environmental, economic (as discussed below), tax, social, and other matters. Many laws and regulations require us to obtain and maintain various licenses, permits, and other authorizations, and we cannot guarantee that we will continue to be able to do so. Our failure to comply with applicable laws and regulations could have a material adverse effect on us as a result of litigation or proceedings by private parties, governments, or regulators, including and in addition to those described in Note 17 to the Consolidated Financial Statements entitled "Commitments and Contingencies." Governments or regulators may change the legislative or regulatory frameworks that we operate in without providing us any recourse to address any adverse effects on our business, including, without limitation, regulatory determinations or rules regarding dispute resolution, increasing the amount of our traffic subject to common carrier regulation, business relationships with other railroads, use of embargoes, calculation of our cost of capital or other inputs relevant to computing our revenue adequacy, the prices we charge, changes in tax rates, enactment of new tax laws or tariffs, and revision in tax regulations. Significant legislative activity in Congress or regulatory activity by other government branches or agencies, such as the STB, could expand regulation of railroad operations and pricing for rail services, which could reduce the viability of capital spending on our rail network, facilities, and equipment, and have a material adverse effect on our results of operations, financial condition, and liquidity.

Significant legislative activity in Congress or regulatory activity by other government branches or agencies, such as the STB, could expand regulation of railroad operations and pricing for rail services, which could reduce the viability of capital spending on our rail network, facilities, and equipment, and increase our costs for purchased goods and services. Such legislative or regulatory activity, or recent tariff activity imposed in the U.S. and retaliatory tariffs implemented in other countries, could have a material adverse effect on our results of operations, financial condition, and liquidity. During fiscal year 2025, new tariffs were imposed in the U.S. for imports from a broad range of countries and materials. Several countries also implemented or proposed retaliatory tariffs on imports from the U.S., as well as other barriers to trade. Incremental import tariffs adversely affected demand for our services and increased our costs for purchased goods and services during fiscal year 2025 and may continue to do so in 2026. In addition, retaliatory tariffs by regions outside the U.S., currently in effect or adopted in the future, may impact demand for our services and our costs for purchased goods and services.

We Face Competition from Other Railroads and Other Transportation Providers – We face competition from other railroads, motor carriers, ships, barges, and pipelines. Our main railroad competitor is Burlington Northern Santa Fe LLC. Its primary subsidiary, BNSF Railway Company (BNSF), operates parallel routes in many of our main traffic corridors. In addition, we operate in corridors served by other railroads and motor carriers. Motor carrier competition exists in all three of our commodity groups. Because of the proximity of our routes to major inland and Gulf Coast waterways, barges can be particularly competitive, especially for grain and bulk commodities in certain areas where we operate. In addition to price competition, we face competition with respect to transit times, quality, and reliability of service from motor carriers and other railroads. Motor carriers in particular can have an advantage over railroads with respect to transit times and timeliness of service. Additionally, we must build or acquire and maintain our rail system, while trucks, barges, and maritime operators are able to use public rights-of-way maintained by public entities. Any of the following could also affect the competitiveness of our transportation services for some or all of our commodities, which could have a material adverse effect on our results of operations, financial condition, and liquidity: (a) improvements or expenditures materially increasing the quality or reducing the costs of these alternative modes of transportation, such as autonomous or more fuel efficient trucks, (b) legislation that eliminates or significantly increases the existing size or weight limitations applied to motor carriers, or (c) legislation or regulatory changes that impose operating restrictions or requirements on railroads or that adversely affect the profitability of some or all railroad traffic. Many movements face product or geographic competition where our customers can use different products (e.g., natural gas instead of coal, sorghum instead of corn) or commodities from different locations (e.g., grain from states or countries that we do not serve, crude oil from different regions). Sourcing different commodities or different locations allows shippers to substitute different carriers, and such competition may reduce our volumes or constrain prices. Additionally, any future consolidation of the rail industry could materially affect our competitive environment.

Current wording

We face competition from other railroads and other transportation providers – We face competition from other railroads, motor carriers, ships, barges, and pipelines. Our main railroad competitor is Burlington Northern Santa Fe LLC. Its primary subsidiary, BNSF Railway Company (BNSF), operates parallel routes in many of our main traffic corridors. In addition, we operate in corridors served by other railroads and motor carriers. Motor carrier competition exists in all three of our commodity groups. Because of the proximity of our routes to major inland and Gulf Coast waterways, barges can be particularly competitive, especially for grain and bulk commodities in certain areas where we operate. In addition to price competition, we face competition with respect to transit times, quality, and reliability of service from motor carriers and other railroads. Motor carriers in particular generally have an advantage over railroads with respect to transit times and timeliness of service. Additionally, we must build or acquire and maintain our rail system, while trucks, barges, and maritime operators are able to use public rights-of-way maintained by public entities. Any of the following could also affect the competitiveness of our transportation services for some or all of our commodities, which could have a material adverse effect on our results of operations, financial condition, and liquidity: (a) improvements or expenditures materially increasing the quality or reducing the costs of these alternative modes of transportation, such as autonomous or more fuel efficient trucks, (b) legislation that eliminates or significantly increases the existing size or weight limitations applied to motor carriers, or (c) legislation or regulatory changes that impose operating restrictions or requirements on railroads or that adversely affect the profitability of some or all railroad traffic. Many movements face product or geographic competition where our customers can use different products (e.g., natural gas instead of coal, sorghum instead of corn) or commodities from different locations (e.g., grain from states or countries that we do not serve, crude oil from different regions). Sourcing different commodities or different locations allows shippers to substitute different carriers, and such competition may reduce our volumes or constrain prices. Additionally, any future consolidation of the rail industry could result in increased competition among industry participants.

We May Be Affected by Climate Change and Market or Regulatory Responses to Climate Change – Climate change, including the impact of global warming and transition risks involving policy, legal risks, and market risks, could have a material adverse effect on our results of operations, financial condition, and liquidity on both a long-term and near-term basis. Restrictions, caps, taxes, or other controls on emissions of GHGs, including diesel exhaust, could significantly increase our operating costs. Restrictions on emissions could also affect our customers that (a) use commodities that we carry to produce energy, (b) use significant amounts of energy in producing or delivering the commodities we carry, or (c) manufacture or produce goods that consume significant amounts of energy or burn fossil fuels, including chemical producers, farmers and food producers, and automakers and other manufacturers. Significant cost increases, government regulation, or changes of consumer preferences for goods or services relating to alternative sources of energy, emissions reductions, and GHG emissions can materially affect the markets for the commodities we carry and demand for our services, which in turn could have a material adverse effect on our results of operations, financial condition, and liquidity. Government incentives encouraging the use of alternative sources of energy also can affect certain of our customers and the markets for certain of the commodities we carry in a manner that could unpredictably alter our traffic patterns or reduce demand.

Previous wording

We Are Affected by Fluctuating Fuel Prices – Fuel costs constitute a significant portion of our transportation expenses. Diesel fuel prices can be subject to dramatic fluctuations, and significant price increases could have a material adverse effect on our operating results. Although we currently are able to recover a significant amount of our fuel expenses from our customers through revenues from fuel surcharges, we cannot be certain that we will always be able to mitigate rising or elevated fuel costs through our fuel surcharges. Additionally, future market conditions or legislative or regulatory activities could adversely affect our ability to apply fuel surcharges or adequately recover increased fuel costs through fuel surcharges. As fuel prices fluctuate, our fuel surcharge programs trail such fluctuations in fuel prices by approximately two months and are from time-to-time a significant source of quarter-over-quarter and year-over-year volatility, particularly in periods of rapidly changing prices. International, political, and economic factors, events and conditions, including international armed conflicts such as the Russia-Ukraine and Israel-Hamas wars, and other geopolitical tensions in the Middle East, affect the volatility of fuel prices and supplies. Weather can also affect fuel supplies and limit domestic refining capacity. A severe shortage of, or disruption to, domestic fuel supplies could have a material adverse effect on our results of operations, financial condition, and liquidity. Alternatively, lower fuel prices could have a negative impact on certain commodities we transport, such as coal and domestic drilling-related shipments, which could have a material adverse effect on our results of operations, financial condition, and liquidity.
