**CSX CORPORATION**

**PART I**

**Item 1. Business**

CSX Corporation, together with its subsidiaries ("CSX" or the "Company"), based in Jacksonville, Florida, is one of the nation's leading transportation companies. The Company provides rail-based freight transportation services including traditional rail service, the transport of intermodal containers and trailers, as well as other transportation services such as rail-to-truck transfers and bulk commodity operations. CSX and the rail industry provide customers with access to an expansive and interconnected transportation network that plays a key role in North American commerce and is critical to the long-term economic success and improved global competitiveness of the United States. In addition, freight railroads provide the most economical and environmentally efficient means to transport goods over land.

*CSX Transportation, Inc.*

CSX's principal operating subsidiary, CSX Transportation, Inc. ("CSXT"), provides an important link to the transportation supply chain through its approximately 20,000 route-mile rail network and serves major population centers in 26 states east of the Mississippi River, the District of Columbia and the Canadian provinces of Ontario and Quebec. It has access to over 70 ocean, river and lake port terminals along the Atlantic and Gulf Coasts, the Mississippi River, the Great Lakes and the St. Lawrence Seaway. This access allows the Company to meet the dynamic transportation needs of manufacturers, industrial producers, the automotive industry, construction companies, farmers and feed mills, wholesalers and retailers, and energy producers. The Company's intermodal business links customers to railroads via trucks and terminals. CSXT also serves thousands of production and distribution facilities through track connections with other Class I railroads and approximately 250 short-line and regional railroads.

CSXT is also responsible for the Company's real estate sales, leasing, acquisition and management and development activities. Substantially all of these activities are focused on supporting railroad operations.

*Other Entities*

In addition to CSXT, the Company's subsidiaries include Quality Carriers, Inc. ("Quality Carriers"), CSX Intermodal Terminals, Inc. ("CSX Intermodal Terminals"), Total Distribution Services, Inc. ("TDSI"), TRANSFLO Terminal Services, Inc. ("TRANSFLO"), CSX Technology, Inc. ("CSX Technology") and other subsidiaries. Quality Carriers is the largest provider of bulk liquid chemicals truck transportation in North America. CSX Intermodal Terminals owns and operates a system of intermodal terminals, predominantly in the eastern United States, and also provides drayage services (the pickup and delivery of intermodal shipments) for certain customers. TDSI serves the automotive industry with distribution centers and storage locations. TRANSFLO connects non-rail served customers to the many benefits of rail by transferring products from rail to trucks. The biggest TRANSFLO markets are chemicals and agriculture, which includes shipments of plastics and ethanol. CSX Technology and other subsidiaries provide support services for the Company.

*Operating Model*

The Company is focused on developing and strictly maintaining a scheduled service plan with an emphasis on improving customer service, optimizing assets and increasing employee engagement. When this operating model is executed effectively, the Company competes for additional business in the U.S. freight market. Further, this model leads to reduced costs and strong free cash flow generation.

*Lines of Business*

During 2025, the Company's services generated $14.1 billion of revenue and served four primary lines of business: merchandise, intermodal, coal and trucking.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merchandise business shipped 2.6 million carloads (41% of volume) and generated $8.8 billion in revenue (62% of revenue) in 2025. The Company's merchandise business is comprised of shipments in the following diverse markets: chemicals, agricultural and food products, automotive, minerals, forest products, metals and equipment, and fertilizers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The intermodal business shipped 3.0 million units (48% of volume) and generated $2.1 billion in revenue (15% of revenue) in 2025. The intermodal business combines the superior economics of rail transportation with the flexibility of trucks and offers a cost and environmental advantage over long-haul trucking. Through a network of approximately 30 terminals, the intermodal business serves all major markets east of the Mississippi River and transports mainly manufactured consumer goods in containers, providing customers with truck-like service for longer shipments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The coal business shipped 718 thousand carloads (11% of volume) and generated $1.9 billion in revenue (13% of revenue) in 2025. The Company transports domestic coal, coke and iron ore to electricity-generating power plants, steel manufacturers and industrial plants as well as export coal to deep-water port facilities. Most of the export coal the Company transports is used for steelmaking, while the majority of domestic coal the Company ships is used for electricity generation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trucking business generated $816 million, or 6%, of revenue in 2025. Trucking revenue includes revenue from the operations of Quality Carriers.

Other revenue accounted for 4% of the Company's total revenue in 2025. This category includes revenue from regional subsidiary railroads and incidental charges, including intermodal storage and equipment usage, demurrage and switching. Revenue from regional subsidiary railroads includes shipments by railroads that the Company does not directly operate. Intermodal storage represents charges for customer storage of containers at an intermodal terminal, ramp facility or offsite location beyond a specified period of time. Demurrage represents charges assessed when freight cars are held by a customer beyond a specified period of time. Switching represents charges assessed when a railroad switches cars for a customer or another railroad.

*CSX's Committed Workforce*

Most of the Company's employees provide or support transportation services. The Company had approximately 23,000 employees as of December 2025, which includes approximately 16,900 employees that are members of a rail labor union and covered by national agreements with the Class I railroads or CSX-specific agreements. As of the date of this filing, new agreements with an effective date of January 1, 2025, have been fully ratified by most unions, representing nearly 75% of the Company's unionized workforce. The remaining unionized employees are covered under previous agreements while negotiations take place since collective agreements under the Railway Labor Act do not expire, but continue until amended or replaced.

CSX prioritizes workplace safety for employees and is committed to continued improvement through enhanced processes, training, technology, communication, and continuous collaboration with customers and peers across the railroad industry. Training programs and processes are focused on injury and accident prevention as well as emergency preparedness. Additionally, the attainment of key safety targets is a component of management's annual incentive program. The FRA Personal Injury Frequency Index, a measure of the number of FRA-reportable injuries per 200,000 man-hours, was 0.94 in 2025 and 1.23 in 2024.

**CSX CORPORATION**

**PART I**

The Compensation and Talent Management Committee of the Board of Directors is responsible for the oversight of the Company's workforce and human capital management processes. The Company is committed to developing a culture that promotes workforce satisfaction and expects ethical behavior. The CSX Code of Ethics serves as a guiding standard for ethical behavior and covers many types of matters, including discrimination and harassment as well as safety. Annually, all management employees are required, and union employees are highly encouraged, to complete ethics training.

**Company History**

A leader in freight rail transportation for nearly 200 years, the Company's heritage dates back to the early nineteenth century when The Baltimore and Ohio Railroad Company ("B&O"), the nation's first common carrier, was chartered in 1827. Since that time, the Company has built on this foundation to create a railroad that could safely and reliably service the ever-increasing demands of a growing nation. Since its founding, numerous railroads have combined with the former B&O through merger and consolidation to create what has become CSX. Each of the railroads that combined into the CSX family brought new geographical reach to valuable markets, gateways, cities, ports and transportation corridors.

CSX Corporation was incorporated in 1978 under Virginia law. In 1980, the Company completed the merger of the Chessie System and Seaboard Coast Line Industries into CSX. The merger allowed the Company to connect northern population centers and Appalachian coal fields to growing southeastern markets. Later, the Company's acquisition of key portions of Conrail, Inc. ("Conrail") allowed CSXT to link the northeast, including New England and the New York metropolitan area, with Chicago and midwestern markets as well as the growing areas in the Southeast already served by CSXT. This current rail network, which now includes the network acquired from Pan Am, allows the Company to directly serve every major market in the eastern United States with safe, dependable, environmentally responsible and fuel efficient freight transportation and intermodal service.

**Competition**

The business environment in which the Company operates is highly competitive. Shippers typically select transportation providers that offer the most compelling combination of service and price. Service requirements, both in terms of transit time and reliability, vary by shipper and commodity. As a result, the Company's primary competition varies by commodity, geographic location and mode of available transportation and includes other railroads, motor carriers that operate similar routes across its service area and, to a less significant extent, barges, ships and pipelines.

CSXT's primary rail competitor is Norfolk Southern Railway, which operates throughout much of the Company's territory. During 2025, Norfolk Southern Railway entered into an agreement to merge with Union Pacific Railroad to form the nation's only transcontinental rail network, which requires the approval of the Surface Transportation Board. Other railroads also operate in parts of the Company's territory. Depending on the specific market, competing railroads and deregulated motor carriers may exert pressure on price and service levels. For further discussion on the risk of competition to the Company, see Item 1A. *Risk Factors*.

**Regulatory Environment**

The Company's operations are subject to various federal, state, provincial (Canada) and local laws and regulations generally applicable to businesses operating in the United States and Canada. In the U.S., the railroad operations conducted by the Company's subsidiaries, including CSXT, are subject to the regulatory jurisdiction of the Surface Transportation Board ("STB"), the Federal Railroad Administration ("FRA"), and its sister agency within the U.S. Department of Transportation ("DOT"), the Pipeline and Hazardous Materials Safety Administration ("PHMSA"). Together, FRA and PHMSA have broad jurisdiction over railroad operating standards and practices, including track, freight cars, locomotives and hazardous materials requirements. In addition, the U.S. Environmental Protection Agency ("EPA") has regulatory authority with respect to matters that impact the Company's properties and operations.

The Transportation Security Administration ("TSA"), a component of the Department of Homeland Security, has broad authority over railroad operating practices that may have homeland security implications. In Canada, the railroad operations conducted by the Company's subsidiaries, including CSXT, are subject to the regulatory jurisdiction of the Canadian Transportation Agency.

Although the Staggers Act of 1980 significantly deregulated the U.S. rail industry, the STB has broad jurisdiction over rail carriers. The STB regulates routes, fuel surcharges, conditions of service, rates for non-exempt traffic, acquisitions of control over rail common carriers and the transfer, extension or abandonment of rail lines, among other railroad activities. Any new rules from the STB regarding, among other things, competitive access or revenue adequacy could have a material adverse effect on the Company's financial condition, results of operations and liquidity as well as its ability to invest in enhancing and maintaining vital infrastructure. For further discussion on regulatory risks to the Company, see Item 1A. *Risk Factors*.

**Item 1A. Risk Factors**

The risks set forth in the following risk factors could have a material adverse effect on the Company's financial condition, results of operations or liquidity, and could cause those results to differ materially from those expressed or implied in the Company's forward-looking statements. Additional risks and uncertainties not currently known to the Company or that the Company currently does not deem to be material also may materially impact the Company's financial condition, results of operations or liquidity.

**<u>Regulatory, Legislative and Legal</u>**

***New legislation, regulatory changes or other governmental actions could impact the Company's earnings or restrict its ability to independently negotiate prices.***

Legislation passed by Congress or state or local assemblies; new regulations issued by federal, state or local agencies; executive orders issued by the President of the United States or governors; or other governmental actions could significantly affect the revenues, costs (including income taxes), and profitability of the Company's business. In addition, statutes, regulations, orders or other governmental actions that, among other things, impose price constraints, restrict access to government funding, or affect rail-to-rail competition could adversely affect the Company's profitability.

***Government regulation and compliance risks may adversely affect the Company's operations and financial results.***

The Company is subject to the jurisdiction of various regulatory agencies, including the STB, FRA, PHMSA, TSA, EPA and other state, provincial, local and federal regulatory agencies for a variety of economic, health, safety, labor, environmental, tax, legal, cybersecurity and other matters. New or modified rules or regulations by these agencies could increase the Company's operating costs, adversely impact revenue or reduce operating efficiencies and affect service performance. Noncompliance with applicable laws or regulations could erode public confidence in the Company and can subject the Company to fines, penalties and other legal or regulatory sanctions.

***CSXT, as a common carrier by rail, is required by law to transport hazardous materials and could be adversely impacted by non-compliance with applicable regulations or from regulatory and legislative changes.***

CSXT is required to comply with regulations regarding the handling of hazardous materials and has a legal obligation to transport certain hazardous materials under the common carrier mandate. Applicable rules issued by the TSA place significant security and safety requirements on passenger and freight railroad carriers, rail transit systems and facilities that ship hazardous materials by rail. Noncompliance with these rules can subject the Company to significant penalties and could be a factor in litigation arising out of a train accident. Finally, legislation preventing the transport of hazardous materials through certain cities could result in network congestion and increase the length of haul for hazardous substances, which could increase operating costs, reduce operating efficiency or increase the risk of an accident involving the transport of hazardous materials.

***The Company may be subject to various claims and lawsuits that could result in significant expenditures.***

As part of its railroad and other operations, the Company is subject to various claims and lawsuits related to disputes over commercial practices, labor and unemployment matters, occupational and personal injury claims, property damage or freight damage, environmental and other matters. The Company may experience material judgments or incur significant costs to defend existing and future lawsuits. Although the Company maintains insurance to cover some of these types of claims and establishes reserves when appropriate, final amounts determined to be due on any outstanding matters may exceed the Company's insurance coverage or differ materially from the recorded reserves. Additionally, the Company could be impacted by adverse developments not currently reflected in the Company's reserve estimates.

**<u>Operational, Safety and Business Disruption</u>**

***The Company relies on the security, stability and availability of its technology systems to operate its business.***

The Company relies on information technology in all aspects of its business. The security, stability and availability of the Company's and its key third-party vendors' information technology systems are critical to its ability to operate safely and effectively and to compete within the transportation industry. A successful data breach, cyber-attack, or the occurrence of any similar incident that impacts the Company's or its key third-party vendors' information technology systems could result in a service interruption, train accident, misappropriation of confidential or proprietary information (including personal information), process failure, or other operational difficulties. A disruption or compromise of the Company's or its key third-party vendors' information technology systems, even for short periods of time, and any resulting theft or compromise of Company confidential or proprietary information (including personal information), could adversely affect the Company's business or reputation, create significant legal, regulatory or financial exposure and have a material adverse impact on CSX's business, financial condition or operations.

The Company, its third-party vendors and other companies in the rail and transportation industries have been subject to, and are likely to continue to be the target of, data breaches, cyber-attacks and other similar incidents. These incidents may include, among other things, malware, ransomware, distributed denial of service attacks, social engineering, phishing, theft, malfeasance or improper access by employees or third-party vendors, software bugs, server malfunctions, software or hardware failures, human error, fraud, or other modes of attack or disruption. Attacks of these nature are increasing in frequency, levels of persistence, intensity and sophistication, including by nation-state threat actors or those associated with nation-states. Further, the Company may be at increased risk of experiencing a cyber-attack as a result of being a component of the critical U.S. infrastructure. If such an event takes place, the Company may be required to incur significant expenses in excess of existing cybersecurity insurance coverage. As cybersecurity threats continue to evolve, including the increased maturity of artificial intelligence leveraged by threat actors, the Company may be required to expend significant additional resources to continue to modify or enhance its protective measures or to investigate and remediate any information security vulnerabilities, data breaches, cyber-attacks or other similar incidents. The Company or its third-party vendors may also experience cybersecurity incidents as a result of employees, third-party vendors and other third parties with which they interact working remotely on less secure systems and environments.

Despite the Company's efforts to protect its information technology systems, it may not be able to prevent or anticipate all data breaches, cyber-attacks or other similar incidents, detect or react to such incidents in a timely manner or adequately remediate any such incident. Due to applicable laws, rules and regulations or contractual obligations, CSX may be held responsible for data breaches, cyber-attacks

**PART I**

or other similar incidents attributed to its third-party vendors as they relate to the information CSX shares with them.

Additionally, if CSX is unable to successfully acquire, develop, implement, or update new or existing technology, including artificial intelligence, it may suffer adverse financial impacts or a competitive disadvantage within the rail industry and with companies providing other modes of transportation services.

***Network or supply chain constraints could have a negative impact on service, operating efficiency or volume of shipments.***

CSXT has experienced, and in the future could experience, rail network difficulties related to: (i) locomotive or crew shortages; (ii) labor shortages or other service disruptions in the supply chain affecting trucking, ports, handling facilities, customer facilities or other railroads; (iii) unpredictable increases in demand; (iv) extreme weather conditions; (v) regulatory changes resulting in forced access or impacting where and how fast CSXT can transport freight or maintain routes; (vi) reductions in availability of pooled equipment, including chassis; (vii) impacts from changes in network capacity or structure; (viii) increased passenger activities; or (ix) derailments and other accidents, which could impact CSXT's operational fluidity, leading to deterioration of service, asset utilization and overall efficiency.

***CSXT, as a common carrier by rail, transports hazardous materials, which could expose the Company to significant costs and claims in the event of a train accident.***

A train accident involving the transport of hazardous materials could result in significant costs and claims arising from personal injury, property or natural resource damage, environmental penalties and remediation obligations. Such claims, if insured, could exceed existing insurance coverage or insurance may not continue to be available at commercially reasonable rates, which could have a material adverse effect on the Company's results of operations, financial condition, and liquidity. Under federal regulations, CSXT is required to transport certain hazardous materials under the legal duty referred to as the common carrier mandate regardless of risk or potential exposure to loss.

***An epidemic or pandemic and the initiatives to reduce its transmission could adversely affect the Company's business.***

The Company has been and could in the future be materially and adversely affected by a public health crisis, including a widespread epidemic or pandemic. During a health crisis, policies and initiatives may be instituted by the public and private sector to reduce transmission, such as closures of businesses and manufacturing facilities, the promotion of social distancing, the adoption of working from home by companies and institutions, and travel restrictions. These policies or initiatives could adversely affect demand for the commodities and products that the Company transports, including import and export volume.

In addition, initiatives to reduce transmission could result in supply chain disruptions, which could impact volumes and make it more difficult for the Company to serve its customers. Moreover, operations are negatively affected when a significant number of employees are quarantined as the result of exposure to a contagious illness. To the extent a public health crisis adversely affects the Company's business and financial results, it may also have the effect of heightening many of the other risks described herein.

***Future acts of terrorism, war or regulatory changes to combat the risk of terrorism may cause significant disruptions in the Company's operations.***

Terrorist attacks, along with any government response to those attacks, may adversely affect the Company's financial condition, results of operations or liquidity. CSXT's rail lines, other key infrastructure and information technology systems may be targets or indirect casualties of acts of terror or war. This risk could cause significant business interruption and result in increased costs and liabilities and decreased revenues. In addition, premiums charged for some or all of the insurance coverage currently maintained by the Company could increase dramatically, or the coverage may no longer be available.

Federal, state and local governmental bodies have adopted legislation and regulations relating to security issues that impact the transportation industry. For example, the Department of Homeland Security adopted regulations that require freight railroads to implement additional security protocols when transporting hazardous materials. Complying with these or future regulations could continue to increase the Company's operating costs and reduce operating efficiencies.

***Severe weather or other natural occurrences could result in significant business interruptions and expenditures in excess of available insurance coverage.***

The Company's operations may be affected by external factors such as severe weather and other natural occurrences, including floods, hurricanes, fires and earthquakes. As a result, the Company's rail network may be damaged, its workforce may be unavailable, fuel costs may rise and significant business interruptions could occur. In addition, the performance of locomotives and railcars could be adversely affected by extreme weather conditions. Hurricanes as well as storm and flooding events have impacted the Company's network in the past, leading to interrupted service and damage to track structure and equipment. Changes in weather patterns are expected to increase the frequency, severity or duration of certain adverse weather conditions.

Insurance maintained by the Company to protect against loss of business and other related consequences resulting from these natural occurrences is subject to coverage limitations, depending on the nature of the risk insured. This insurance may not be sufficient to cover all of the Company's damages or damages to others, and this insurance may not continue to be available at commercially reasonable rates. Even with insurance, if any natural occurrence leads to a catastrophic interruption of service, the Company may not be able to restore service without a significant interruption to operations.

**<u>Competitive, Economic and Financial</u>**

***The Company faces competition from other transportation providers.***

The Company experiences competition in pricing, service, reliability and other factors from various transportation providers including railroads and motor carriers that operate similar routes across its service area and, to a less significant extent, barges, ships and pipelines. Other transportation providers generally use public rights-of-way that are built and maintained by governmental entities, while CSXT and other railroads must build and maintain rail networks largely using internal resources. Any future improvements or expenditures materially increasing the quality or reducing the cost of alternative modes of transportation such as through the use of automation, autonomy or electrification, or legislation providing for less stringent size or weight restrictions on trucks, could negatively impact the Company's competitive position. Additionally, any currently proposed or other future consolidation in the rail industry could materially affect the regulatory and competitive environment in which the Company operates.

***Global economic conditions could negatively affect demand for commodities and other freight.***

A decline or disruption in general domestic and global economic conditions that affects demand for the commodities and products the Company transports, including import and export volume, could reduce revenues or have other adverse effects on the Company's cost structure and profitability. For example, slower rates of economic growth in Asia, contraction of European economies, and changes in the global supply of seaborne coal or price of seaborne coal have adverse impacts on U.S. export coal volume and result in lower coal revenue for CSX. Additionally, embargoes or changes to trade agreements or policies, such as tariffs, could result in reduced import and export volumes. If the Company experiences significant declines in demand for its transportation services with respect to one or more commodities and products or continues to experience the impacts of inflation, the Company may experience reduced revenue and increased operating costs, workforce adjustments, and other related activities, which could have a material adverse effect on the Company's financial condition, results of operations and liquidity.

***Changing dynamics in the U.S. and global energy markets could negatively impact profitability.***

Over time, changing dynamics in the U.S. and global energy markets, including the impacts of regulation and alternative fuel sources, have resulted in lower energy production from coal-fired power plants in CSX's service territory. Changes in natural gas prices, or other factors impacting demand for electricity, could impact future power generation at coal-fired plants, which would affect the Company's coal volumes and revenues.

***Weaknesses in the capital and credit markets could negatively impact the Company's access to capital.***

The Company regularly relies on capital markets for the issuance of long-term debt instruments, commercial paper and bank financing from time to time. Instability or disruptions of the capital markets, including credit markets, significant increases in interest rates, or the deterioration of the Company's financial condition due to internal or external factors, could restrict or prohibit access and could increase financing costs. A significant deterioration of the Company's financial condition could also reduce credit ratings and could limit or affect its access to external sources of capital and increase the costs of short and long-term debt financing.

**<u>Availability of Critical Supplies and Labor</u>**

***The unavailability of critical resources could adversely affect the Company's operational efficiency and ability to meet demand.*** 

Marketplace conditions for resources like locomotives and the availability of qualified personnel, including engineers and conductors as well as other skilled professional or technical employees, could each have a negative impact on the Company's ability to meet demand for rail service. Although the Company strives to maintain adequate resources and personnel for the current business environment, unpredictable increases in demand for rail services or extreme weather conditions may exacerbate such risks, which could have a negative impact on the Company's operational efficiency and otherwise have a material adverse effect on the Company's financial condition, results of operations, or liquidity in a particular period.

***Disruption to a key railroad industry supplier could negatively affect operating efficiency and increase costs.***

The capital intensive and unique nature of core rail equipment (including rail, ties, freight cars and locomotives) limits the number of railroad equipment suppliers. If any of the current manufacturers stops production or experiences a supply shortage, CSXT could experience a significant cost increase or material shortage. In addition, a few critical railroad suppliers are foreign and, as such, adverse developments in international relations, new trade regulations, disruptions in international shipping or increases in global demand could make procurement of these supplies more difficult or increase CSXT's costs. Additionally, if a fuel supply shortage were to arise, the Company would be negatively impacted.

***Failure to complete negotiations on collective bargaining agreements could result in strikes and/or work stoppages.***

Most of CSX's employees are represented by labor unions and are covered by collective bargaining agreements. These agreements are either bargained for nationally by the National Carriers Conference Committee or locally between CSX and the union. Such agreements are negotiated over the course of several years and previously have not resulted in any extended work stoppages. Under the Railway Labor Act's procedures (which include mediation, cooling-off periods and the possibility of an intervention by the President of the United States), during negotiations neither party may take action until the procedures are exhausted. If, however, CSX is unable to negotiate acceptable agreements, the employees covered by the Railway Labor Act could strike, which could result in loss of business and increased operating costs as a result of higher wages or benefits paid to union members.

**<u>Climate and Environmental</u>**

***The Company's operations and financial results could be negatively impacted by climate or weather-related risks as well as regulatory and legislative responses.***

There is potential for operational impacts from climate-related risks, including changing weather patterns, in the Company's operational territory, which could impact the Company's network or other assets.

Climate and emissions-related laws and regulations have been proposed and, in some cases adopted, on the federal, state, provincial and local levels. These final and proposed laws and regulations take the form of restrictions, caps, taxes or other controls on emissions as well as requirements to disclose climate-related information. In particular, the EPA has issued various regulations and may issue additional regulations targeting emission reductions, including rules and standards governing emissions from certain stationary and mobile sources. Any of these pending or proposed laws or regulations, could adversely affect the Company's operations and financial results by, among other things: (i) reducing coal-fired electricity generation due to mandated emission standards; (ii) reducing the consumption of coal as a viable energy resource in the United States and Canada; (iii) increasing the Company's fuel, capital and other operating costs and negatively affecting operating and fuel efficiencies; and (iv) making it difficult for the Company's customers in the U.S. and Canada to produce products in a cost competitive manner. Any of these factors could reduce the amount of shipments the Company handles and have a material adverse effect on the Company's financial condition, results of operations or liquidity. In addition, CSX may become subject to legal requirements to disclose climate-related information and may become subject to demands or expectations by its supply chain partners, customers or other stakeholders to disclose information relating to climate risk or set related targets or goals. The Company's current practices with respect to climate risk disclosure may fail to meet these developing legal requirements or stakeholder demands or expectations. In addition, legislative or regulatory uncertainties and change regarding climate-related risks, including inconsistent perspectives or requirements, are likely to result in higher regulatory, compliance, credit, reputational and other risks and costs.

***The Company is subject to environmental laws and regulations that may result in significant costs.***

The Company is subject to wide-ranging federal, state, provincial and local environmental laws and regulations concerning, among other things, emissions into the air, ground and water; the handling, storage, use, generation, transportation and disposal of waste and other materials; the clean-up of hazardous material and petroleum releases and the health and safety of our employees. If the Company violates or fails to comply with these laws and regulations, CSX could be fined or otherwise sanctioned by regulators. The Company can also be held liable for consequences arising out of human exposure to any hazardous or otherwise harmful substances that CSX is transporting or storing. In certain circumstances, environmental liability can extend to formerly owned or operated properties, leased properties, adjacent properties and properties owned by third parties or Company predecessors, as well as to properties currently owned, leased or used by the Company.

The Company has been, and may in the future be, subject to allegations or findings to the effect that it has violated, or is strictly liable under, environmental laws or regulations, and such violations can result in the Company's incurring fines, penalties or costs relating to the cleanup of environmental contamination. Although the Company believes it has appropriately recorded current and long-term liabilities for known and reasonably estimable future environmental costs, it could incur significant costs that exceed reserves or require unanticipated cash expenditures as a result of any of the foregoing. The Company also may be required to incur significant expenses to investigate and remediate known, unknown or future environmental contamination.

**Item 1C. Cybersecurity**

***Cybersecurity Risk Management and Strategy***

Strong performance and reliability of the Company's technology systems are critical to operating safely and effectively, and protecting personal and customer data is essential to maintaining stakeholder trust. The Company has implemented processes designed to assess, identify, and manage material cybersecurity risks, as described further below. CSX maintains a cybersecurity framework that is integrated across the organization through people, processes and technology to help protect the personal information of its customers, its contractors and its suppliers as well as protect the integrity of its own operations. Cybersecurity is also integrated into the Company's Enterprise Risk Management ("ERM") program.

The Company equips CSX systems with various cybersecurity tools, conducts vulnerability scans and provides critical cybersecurity information to application users, as appropriate. The Company also takes proactive measures to advise CSX employees of how they can assist the Company in its cybersecurity practices. CSX informs employees on cybersecurity best practices, including how to identify cyber-related suspicious activity, how to report such activity and, as appropriate, proactive measures employees can take to safeguard company information and devices. The Company also provides cybersecurity awareness training to employees and conducts cybersecurity testing exercises to help maintain cybersecurity vigilance. With the assistance of third-party consultants, the Company conducts an annual cybersecurity exercise, which is often a "tabletop" scenario involving a cross-functional group responding to a hypothetical cybersecurity threat.

The Company considers its material cybersecurity-related risks, as described in more detail below and at Item 1A. *Risk Factors*, and applies various frameworks to establish controls that are reasonably designed to identify, protect, detect, respond to, and recover from significant cybersecurity incidents. The Company also tests its cybersecurity program to assess whether enhancements to cybersecurity measures are appropriate, such as additional detection and prevention capabilities. These tests may include the use of internal or third-party external risk assessments, and penetration testing. The Company also conducts periodic cybersecurity assessments, as appropriate, pursuant to its annual risk assessment process. Third party resources may also be used for these assessments.

As part of its cybersecurity program, CSX partners with a third-party to provide a managed service that is designed to enable continuous monitoring at its Security Operation Center ("SOC"). The SOC has established processes to identify, address, and remediate cybersecurity threats or vulnerabilities. This includes the engagement, where necessary, of third-party experts, advisors, and other cybersecurity professionals that have been retained by the Company to assist in responding to cybersecurity incidents or threats. Company processes also include various procedures for notifying members of the company's cybersecurity department, Chief Information Security Officer ("CISO"), legal department, accounting department, and others as applicable.

The Company has processes designed to provide reasonable oversight for the identification of cybersecurity risks associated with certain third-party service providers. As appropriate, the Company requires certain third-party providers to complete a cybersecurity questionnaire, to provide Service Organization Control assessment results, when such results exist, or to agree to contractual language regarding cybersecurity and incident notification obligations in agreements with the company. CSX also has processes that help monitor risks associated with its key third-party vendors' technology systems, including, where appropriate, performing security assessments of cyber incidents through dashboard alerting for reported events. CSX's internal cybersecurity processes and disclosure protocols consider cybersecurity incidents involving key applications provided by third-parties.

The Company, its third-party vendors and other companies in the rail and transportation industries have been subject to, and are likely to continue to be the target of, data breaches, cyber-attacks and other similar incidents as discussed in more detail in Item 1A. *Risk Factors*. In light of the numerous cybersecurity risks that CSX faces, it is reasonably likely that any of the related risks, individually or collectively, if significant, could materially affect the Company's operations, including but not limited to service interruption, train accident or derailment, misappropriation of confidential or proprietary information (including personal information), process failure, or other operational difficulties.

***Cybersecurity Governance***

The cybersecurity program and related risks at CSX are managed by the Assistant Vice President of Cloud Infrastructure Platforms and CISO. The Company's CISO has over 29 years of industry experience including administration of military command and control systems, infrastructure platforms, process governance, and security architecture. The CISO is supported by a team of dedicated cybersecurity professionals as well as various resources from a Managed Security Service Provider.

The CISO is notified of cybersecurity events as needed based on the Company's processes for addressing cybersecurity incidents and threats. The SOC, with the assistance of outside third-parties as needed, analyzes, evaluates and remediates cybersecurity incidents and provides investigative information to the CISO. Depending on the significance of any specific cybersecurity incident or threat, and/or relation to prior incidents, the CISO will escalate relevant information, as appropriate, and the Company's legal and accounting groups, with assistance from other company departments and third parties, will assist in assessing potential SEC disclosure obligations. The CISO coordinates disclosure to other agencies, when necessary, including requirements under the Transportation Security Administration directives.

More significant cybersecurity incidents or threats may result in notifications to senior leadership and, if necessary, to the Audit Committee and the Board of Directors. Additionally, a cybersecurity governance briefing takes place at least semiannually with leaders from the Company's technology, operations, commercial, legal, and accounting departments to discuss cybersecurity risks, threats, and incidents, as well as updates from the SOC and an assessment of ways to mitigate and remediate any threats or incidents the Company may be facing.

The Company's Audit Committee of the Board of Directors oversees the Company's cybersecurity risk, mitigation strategies and overall resiliency of the Company's technology infrastructure. Such risk is managed as part of the Company's overall risk management and business continuity processes and is included in the ERM program, which is also overseen by the Audit Committee. The Audit Committee periodically reviews assessments of information security controls and procedures, any incidents that could have a potentially significant impact on the company's network, and potential cybersecurity risk disclosures. The Company's senior leadership team briefs the Audit Committee and Board of Directors at least annually on information technology and cybersecurity matters, with more frequent updates as circumstances warrant. Such annual updates include significant findings or other information from internal or external evaluations. The Audit Committee is apprised annually on emerging risks to the Company, including education on cybersecurity-related matters as needed. CSX has a cybersecurity expert on the Board and its Audit Committee to provide expanded oversight of the Company's cybersecurity and technology systems.

**Item 2. Properties**

The Company's properties primarily consist of track and its related infrastructure, locomotives, and freight cars and equipment. These categories and the geography of the network are described below.

*Track and Infrastructure*

Serving 26 states, the District of Columbia, and the Canadian provinces of Ontario and Quebec, the CSXT rail network serves, among other markets, New York, Philadelphia and Boston in the Northeast and Mid-Atlantic, the southeast markets of Atlanta, Miami and New Orleans, and the midwestern markets of St. Louis, Columbus and Chicago.

CSXT's track structure includes mainline track, which connects terminals and yards, track within terminals and switching yards, sidings used for passing trains, track connecting CSXT's track to customer locations and turnouts that divert trains from one track to another. Total track miles, which reflect the size of CSXT's network that connects markets, customers and western railroads, are greater than CSXT's approximately 20,000 route miles. At December 2025, the breakdown of track miles was as follows:

---

| | |
|:---|:---|
| | **Track**<br>**Miles** |
| Single Mainline Track | 19739 |
| Other Mainline Track | 5648 |
| Terminals and Switching Yards | 9243 |
| Passing Sidings and Turnouts | 888 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total | 35518 |

---

In addition to its physical track structure, the Company operates numerous yards and terminals for rail and intermodal service. These serve as points of connectivity between the Company and its local customers and as sorting facilities where railcars and intermodal containers are received, classed for destination and placed onto outbound trains, or arrive and are delivered to the customer. The Company's largest yards and terminals based on 2025 volume (number of railcars or intermodal containers processed) are listed below.

*Network Geography*

CSXT's operations are primarily focused on four major transportation networks and corridors that are defined geographically and by commodity flows below.

<u>Interstate 90 (I-90) Corridor</u> – This CSXT corridor links Chicago and the Midwest to metropolitan areas in New York and New England. This route, also known as the "waterlevel route," has minimal hills and grades and nearly all of it has two main tracks (referred to as double track). These engineering attributes permit the corridor to support high-speed service across intermodal, automotive and other merchandise commodities. This corridor is a primary route for import traffic coming from the far east through western ports moving eastward across the country, through Chicago and into the population centers in the Northeast. The I-90 Corridor is also a critical link between ports in New York, New Jersey, and Pennsylvania and consumption markets in the Midwest. This route carries goods from all three of the Company's major rail markets – merchandise, intermodal and coal.

<u>Interstate 95 (I-95) Corridor</u> – The CSXT I-95 Corridor connects Charleston, Jacksonville, Miami and many other cities throughout the Southeast with the heavily populated mid-Atlantic and northeastern cities of Baltimore, Philadelphia and New York. CSXT primarily transports food and consumer products, as well as metals and chemicals along this line. It is the leading rail corridor along the eastern seaboard south of the District of Columbia and provides access to major eastern ports.

<u>Southeastern Corridor</u> – This critical part of the network runs between CSXT's western gateways of Chicago, St. Louis and Memphis through the cities of Nashville, Birmingham, and Atlanta and markets in the Southeast. The Southeastern Corridor is the premier rail route connecting these key cities, gateways, and markets and positions CSXT to efficiently handle projected traffic volumes of intermodal, automotive and general merchandise traffic.

<u>Coal Network</u> – The CSXT coal network connects the coal mining operations in the Appalachian mountain region and Illinois basin with industrial areas in the Southeast, Northeast and Mid-Atlantic, as well as many river, lake, and deep water port facilities. The domestic coal market has declined significantly over the last decade and export coal remains subject to volatility. CSXT's coal network remains well positioned to supply utility markets in both the Northeast and Southeast and to transport coal shipments for export outside of the U.S. Most of the export coal the Company transports is used for steelmaking, while the majority of domestic coal the Company ships is used for electricity generation.

See the following page for a map of the CSX Rail Network. Also included on the map, "CSX Operating Agreement" indicates areas within which CSX can operate through trackage rights beyond the CSX network.

*Locomotives*

As of December 2025, CSXT owns more than 3,400 locomotives. From time to time, the Company also short-term leases locomotives based on business needs. Freight locomotives are used primarily to pull trains while switching locomotives are used in yards. Auxiliary units are typically used to provide extra traction for heavy trains in hilly terrain. Of owned locomotives, approximately 70% were in active service as of December 31, 2025, and the remainder were in storage to be utilized as needed. Storing locomotives and equipment allows the Company to quickly adjust its active fleet based on demand and other factors while avoiding delays due to supply limitations or excessive lead times to acquire additional equipment. As of December 2025, CSXT's fleet of owned locomotives consisted of the following types:

---

| | | | |
|:---|:---|:---|:---|
| | **Locomotives** | **%** | **Average Age**<br>*(in Years)* |
| Freight | 3167 | 91% | 23 |
| Switching | 191 | 6% | 48 |
| Auxiliary Units | 112 | 3% | 32 |
| &nbsp;&nbsp;&nbsp;&nbsp;**Total Locomotives** | **3470** | 100% | 24 |

---

*Equipment*

The Company owns or long-term leases rail equipment, including several types of freight cars and intermodal containers. Of total owned and long-term leased equipment, approximately 86% was in active service as of December 31, 2025, and the remainder were in storage to be utilized as needed. As of December 2025, the Company's owned and long-term leased equipment consisted of the following:

---

| | | |
|:---|:---|:---|
| **Equipment** | **Number of Units** | **%** |
| Gondolas | 18920 | 43% |
| Multi-level Flat Cars | 10854 | 25% |
| Open-top Hoppers | 6108 | 14% |
| Covered Hoppers | 5155 | 12% |
| Box Cars | 1841 | 4% |
| Flat Cars | 535 | 1% |
| Other Cars | 572 | 1% |
| &nbsp;&nbsp;&nbsp;Subtotal Freight Cars | 43985 | 100% |
| Containers | 17630 |  |
| **Total Equipment** | **61615** |  |

---

At any time, approximately two-thirds of the railcars on the CSXT system are not owned or leased by the Company. Examples of these include railcars owned by other railroads (which are utilized by CSXT), shipper-furnished or private cars (which are generally used only in that shipper's service), multi-level railcars used to transport automobiles (which are shared between railroads) and double-stack railcars, or well cars (which are industry pooled), that allow for two intermodal containers to be loaded one above the other.

**Double-stack** - Stacking containers two-high on specially equipped cars.

**Economic Profit (CSX Cash Earnings or CCE)** - A non-GAAP measure designed to incentivize strategic investments earning more than the required return.

***Revenue***

Total revenue decreased by $448 million in 2025, or 3%, when compared to the previous year primarily due to declines in export coal revenue, which includes the impact of lower global benchmark rates, lower merchandise volume, and lower fuel recovery. These decreases were partially offset by pricing gains in merchandise and higher intermodal volume.

***Merchandise Volume***

<u>Chemicals</u> - Decreased primarily due to lower shipments of crude oil, plastics, petroleum products, and other industrial chemicals.

<u>Agricultural and Food Products</u> – Decreased due to lower shipments of food and consumer products, as well as soybeans, partially offset by higher shipments of domestic feed grain and ingredients.

<u>Automotive</u> - Decreased due to lower North American vehicle production.

<u>Minerals</u> - Increased primarily due to higher shipments of aggregates and cement.

<u>Forest Products</u> – Decreased due to lower shipments of building products, as well as lower shipments of pulp and paper products which includes the impact of both temporary outages and customer plant closures.

<u>Metals and Equipment</u> - Increased scrap shipments were offset by lower aluminum and steel shipments, which includes the impact of plant closures, as well as lower equipment shipments.

<u>Fertilizers</u> - Increased due to higher short-haul phosphates shipments.

***Intermodal Volume***

Intermodal volume increased primarily due to international shipments driven by higher port volumes and growth with key customers. Domestic shipments also increased, despite the impacts of a continued soft trucking environment, due to wins with key customers and new service offerings.

***Coal Volume***

Export coal decreased due to lower shipments of metallurgical and thermal coal, which includes the impacts from outages at customer facilities. Domestic coal increased due to higher shipments to utility plants, partially offset by lower shipments to steel manufacturing locations, as well as lower shipments to river and lake terminals.

***Trucking Revenue***

Trucking revenue decreased $28 million versus the prior year due to lower rates and fuel surcharge.

***Other Revenue***

Other revenue was $31 million higher primarily due to increased carload demurrage.

***Expense***

In 2025, total expenses increased $276 million, or 3%, compared to prior year. Descriptions of each expense category as well as significant year-over-year changes are described below.

<u>Labor and Fringe</u> expenses include employee wages and related payroll taxes, health and welfare costs, incentive compensation, and the costs of other benefits. These expenses increased $97 million due to the following items:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An increase of $67 million was driven by inflation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Employee separation costs increased $51 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An increase of $14 million was due to higher incentive compensation costs, driven mostly by downward accrual adjustments in the prior year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A decrease of $47 million was due to the impacts of lower rail headcount and overtime.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net other costs increased $12 million primarily due to higher trucking headcount, including the impacts from acquiring previously independent affiliates, partially offset by other non-significant net decreases.

<u>Purchased Services and Other</u> expenses consist primarily of contracted services to maintain infrastructure and equipment, terminal and pier services, purchased trucking and other transportation, and professional services. This category also includes costs related to materials, travel, casualty claims, environmental remediation, train accidents, property and sales tax, utilities and other items including gains on property dispositions. Total purchased services and other expenses increased $172 million driven by the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An increase of $53 million was due to the effects of network disruptions and congestion, primarily driven by work on the Howard Street tunnel and severe winter weather. These impacts include rerouting costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An increase of $42 million was due to higher casualty costs related to trucking and higher derailment costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Prior year results included $35 million for a favorable legal settlement and an insurance recovery.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An increase of $25 million was due to higher net unfavorable inventory adjustments and technology impairments compared to the prior year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An increase of $21 million was due to advisory expenses and technology contract restructuring costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• All other costs decreased $4 million as efficiency savings and trucking savings from affiliate conversions were largely offset by the impact of inflation, higher property taxes, and other net increases.

<u>Depreciation</u> expense primarily relates to recognizing the costs of capital assets, such as track structure, locomotives and railcars, over their respective useful lives, which are reviewed periodically as part of depreciation studies. This expense is impacted primarily by the capital expenditures made each year. Depreciation expense increased $22 million primarily due to increases to the asset base, partially offset by asset retirements and impairments.

<u>Fuel</u> expense includes locomotive diesel fuel as well as non-locomotive fuel. This expense is largely driven by the market price and locomotive consumption of diesel fuel. Fuel expense decreased $73 million primarily due to a 7% decrease in locomotive fuel prices.

<u>Equipment and Other Rents</u> expense includes rent paid for freight cars owned by other railroads or private companies, net of rents received by CSXT for use of its equipment. This category of expenses also includes expenses for short-term and long-term leases of locomotives, railcars, containers, tractors and trailers, offices and other rentals. These expenses increased $2 million as increased net car hire costs were largely offset by increased ancillary income.

<u>Goodwill Impairment</u> expense for Quality Carriers was $164 million in 2025 compared to $108 million in 2024.

***Interest Expense***

Interest Expense includes interest on long-term debt and related fair value hedges, equipment obligations and finance leases. Interest expense increased $12 million primarily due to higher average debt balances.

***Other Income - Net***

Other Income - Net includes investment gains, losses, interest income, components of net periodic pension and post-retirement benefit cost and other non-operating activities. Other income decreased $50 million primarily due to lower interest income and lower net pension benefit credits.

***Income Tax Expense***

Income Tax Expense decreased $205 million primarily due to lower earnings before income taxes.

***Net Earnings and Earnings per Diluted Share***

Net Earnings decreased $581 million to $2.9 billion, and earnings per diluted share decreased $0.25 to $1.54, due to the factors mentioned above. Average shares outstanding was lower as a result of share repurchase activity during the year and had a favorable impact on earnings per diluted share.

**NON-GAAP MEASURES** (Unaudited)

CSX reports its financial results in accordance with United States generally accepted accounting principles ("GAAP"). CSX also uses certain non-GAAP measures that fall within the meaning of Securities and Exchange Commission Regulation G and Regulation S-K Item 10(e), which may provide users of the financial information with additional meaningful comparison to prior reported results. Non-GAAP measures do not have standardized definitions and are not defined by GAAP. Therefore, CSX's non-GAAP measures are unlikely to be comparable to similar measures presented by other companies. The presentation of these non-GAAP measures should not be considered in isolation from, as a substitute for, or as superior to the financial information presented in accordance with GAAP. Reconciliations of non-GAAP measures to corresponding GAAP measures are below.

*Adjusted Operating Results*

Management believes that adjusted operating income, adjusted operating margin, adjusted net earnings, and adjusted net earnings per share, assuming dilution are important in evaluating the Company's performance and for planning and forecasting future business operations and future profitability. These non-GAAP measures provide meaningful supplemental information regarding operating results because they exclude non-cash impairment of Quality Carriers' goodwill, which was fully impaired as of September 30, 2025. This is a significant item that is not considered indicative of future financial trends. The goodwill impairment was tax effected using rates reflective of the applicable tax amounts related to the impairment charge. These adjusted results should be considered in addition to, rather than as a substitute for, the Company's GAAP operating results.

The following tables reconcile the Company's GAAP operating results for the years ended December 31, 2025, and December 31, 2024, to adjusted operating results (non-GAAP measures).

*Economic Profit*

Management believes Economic Profit (also referred to as CSX Cash Earnings or CCE) provides an additional perspective to investors about financial returns generated by the business by representing a measure showing profit generated over and above the cost of capital used by the business to generate that profit. Economic Profit is designed to incentivize strategic investments that earn more than management's desired minimum required return and is broadly utilized by management to make investment decisions. Therefore, disclosing Economic Profit on how management performs in this regard provides additional useful information to investors regarding the Company's performance compared to its goals.

Economic Profit should be considered in addition to, rather than a substitute for, operating income, which is the most directly comparable GAAP measure. Economic Profit is defined by the Company as Gross Cash Earnings ("GCE") minus the Capital Charge on Gross Operating Assets ("GOA"). Increases in Economic Profit indicate that the Company is effectively allocating capital and rewarding shareholders by generating returns in excess of the incremental cost of capital associated with reinvestment in the business.

GCE is calculated as operating income plus depreciation, amortization and operating lease expense, less unusual items and taxes. The Capital Charge uses a minimum required return multiplied by the GOA. CSX's GOAs include gross properties and other non-cash assets, net of non-interest bearing liabilities. The Company used a 15% tax rate and an 8% required return, for both periods presented, which is consistent with rates used for investment decisions and performance evaluation within those same periods. The tax rate is the approximate equivalent of the Company's actual income tax expense as a percentage of pre-tax GCE. The required return rate represents management's desired minimum return on any investment. CSX annually re-evaluates these rates to ensure they accurately represent taxes and a required return in light of internal and external factors and would adjust the rate if the annual review resulted in a preset deviation from the current rates. This focuses the Economic Profit measure on value generated by management instead of external factors, such as legislative tax policy or interest rate volatility.

*(a) Unusual items are defined by management as unique events with greater than $100 million full year operating income impact, consistent with the terms of the Company's long-term incentive plan agreements. Impairments of the goodwill of Quality Carriers were unusual items for 2025 and 2024.*

*(b) The tax percentage rate was 15% for both periods presented. This rate is applied to the sum of operating income, depreciation, amortization and operating lease expense, and unusual items.*

*(c) Non-interest bearing liabilities represents all liabilities excluding debt, long-term lease liabilities, and commercial paper ($75 million of commercial paper was outstanding in other current liabilities as of June 30, 2025, and none outstanding in any other period).*

*(d) Gross operating assets reflects an average of the year-to-date quarters reported for each year presented.* 

*(e) The capital charge of 8% for both years is calculated as the minimum return multiplied by gross operating assets.*

*Free Cash Flow*

Management believes free cash flow ("FCF") is useful to investors as it is important in evaluating the Company's financial performance. More specifically, FCF measures cash generated by the business after reinvestment. This measure represents cash available for both equity and bond investors to be used for dividends, share repurchases or principal reduction on outstanding debt. FCF is calculated by using net cash from operations and adjusting for property additions and proceeds and advances from property dispositions. This measure should be considered in addition to, rather than a substitute for, cash provided by operating activities.

FCF before dividends decreased $995 million year-over-year to $1.8 billion primarily due to lower net earnings and the payment of $429 million of previously-postponed federal and state taxes related to the 2024 tax year. Other year-over-year decreases resulting from higher property additions, including approximately $470 million related to rebuilding the Blue Ridge subdivision, as well as a $96 million prepayment for locomotive maintenance services were partially offset by the impact of bonus depreciation and other changes in working capital. Related to tax payments, no 2025 taxes were postponed, but 2024 results included the payment of $387 million of previously-postponed taxes related to the 2023 tax year, offset by postponement of $429 million of taxes related to the 2024 tax year.

The following table reconciles cash provided by operating activities (GAAP measure) to FCF before dividends (non-GAAP measure).

Safety is a top priority at CSX, and the Company is committed to reducing risk and enhancing the overall safety of its employees, customers, and communities in which it operates.

**LIQUIDITY AND CAPITAL RESOURCES**

Liquidity is a company's ability to generate adequate amounts of cash to meet both current and future needs for obligations as they mature and to provide for planned capital expenditures, including those to address regulatory and legislative requirements. To have a complete picture of a company's liquidity, its sources and uses of cash, balance sheet and external factors should be reviewed.

***Significant Cash Flows***

**CSX CORPORATION**

**PART II**

In 2025, the Company generated $634 million less cash from operating activities compared to prior year, primarily driven by lower cash-generating net earnings, the payment of $429 million of previously postponed taxes with no postponements available in 2025, and a $96 million prepayment for locomotive maintenance services. These decreases were partially offset by the impact of bonus depreciation and other changes in working capital. In 2024, the payment of $387 million of previously-postponed taxes related to the 2023 tax year was more than offset by postponement of $429 million of taxes related to the 2024 tax year. CSX used $246 million more cash for investing activities in 2025 compared to 2024, primarily due to higher property additions consistent with planned capital expenditures, including approximately $470 million related to rebuilding the Blue Ridge subdivision as a result of impacts from Hurricane Helene. The $1.0 billion decrease in net spending on financing activities compared to the prior year was driven by fewer share repurchases and higher proceeds from the issuance of long-term debt.

*Sources of Cash and Liquidity*

The Company has multiple sources of liquidity, including cash generated from operations and financing sources. The Company filed a shelf registration statement with the SEC on February 27, 2025, which may be used to issue debt or equity securities at CSX's discretion, subject to market conditions and CSX Board authorization. While CSX seeks to give itself flexibility with respect to cash requirements, there can be no assurance that market conditions would permit CSX to sell such securities on acceptable terms at any given time, or at all. In 2025, CSX issued $900 million of long-term debt. See Note 10, *Debt and Credit Agreements* for more information.

CSX has access to a $1.2 billion five-year unsecured revolving credit facility backed by a diverse syndicate of banks that expires in February 2028. As of December 31, 2025, the Company had no outstanding balances under this facility. The Company also has a commercial paper program, backed by the revolving credit facility, under which the Company may issue unsecured commercial paper notes up to a maximum aggregate principal amount of $1.0 billion outstanding at any one time. As of December 31, 2025, the Company had no outstanding debt under the commercial paper program.

*Uses of Cash*

CSX uses current cash balances for general corporate purposes, which may include capital expenditures, working capital requirements, reduction or refinancing of outstanding indebtedness, redemptions and repurchases of CSX common stock, dividends to shareholders, acquisitions and other business opportunities, and contributions to the Company's qualified pension plan.

In 2025, CSX continued to invest in its business to create long-term value for shareholders. The Company is committed to maintaining and improving its existing infrastructure and to positioning itself for long-term, profitable growth through optimizing network and terminal capacity. Funds used for property additions are further described below.

Capital expenditures above include approximately $470 million and $50 million in 2025 and 2024, respectively, related to rebuilding the Blue Ridge subdivision as a result of impacts from Hurricane Helene. Planned capital investments for 2026 are expected to be less than $2.4 billion. Spending to sustain core infrastructure with a focus on safety and reliability will be a top priority. In addition, management is committed to investments that promote profitable growth, including projects supporting service enhancements and productivity initiatives, including investments in locomotives and freight cars. CSX intends to fund capital investments primarily through cash generated from operations.

CSX is continually evaluating market and regulatory conditions that could affect the Company's ability to generate sufficient returns on capital investments. CSX may revise its future estimates for capital spending as a result of changes in business conditions, tax legislation or the enactment of new laws or regulations, which could have a material adverse effect on the Company's operations and financial performance in the future (see *Risk Factors* under Item 1A of this Form 10-K).

CSX is committed to returning cash to shareholders. Capital structure, capital investments and cash distributions, including dividends and share repurchases, are reviewed at least annually by the Board of Directors. On February 12, 2025, the Company's Board of Directors authorized an 8% increase in the quarterly cash dividend to $0.13 per common share effective March 2025. The 2025 dividend increase was the 21<sup>st</sup> consecutive increase in CSX's annual dividend. Management's assessment of market conditions and other factors guides the timing and volume of repurchases. Future share repurchases are expected to be funded by cash on hand, cash generated from operations and debt issuances.

***Material Changes in the Consolidated Balance Sheets and Working Capital***

CSX's balance sheet reflects its strong capital base and the impact of CSX's balanced approach in deploying capital for the benefit of its shareholders, which includes investments in infrastructure, dividend payments and share repurchases. Further, CSX is well positioned from a liquidity standpoint. The Company ended the year with $675 million of cash, cash equivalents and short-term investments.

Total assets as well as total liabilities and shareholders' equity increased $918 million from prior year end. The increase in total assets was primarily due to a $1.2 billion increase in net properties consistent with planned capital expenditures, including additions related to rebuilding the Blue Ridge subdivision. Additionally, investments in affiliates and other companies increased $114 million driven by affiliate earnings and other current assets increased due to a $96 million prepayment of locomotive maintenance expenses. These increases were partially offset by a $263 million decrease in cash and cash equivalents as noted above and a $164 million impairment of Quality Carriers' goodwill.

Total liabilities increased $265 million from prior year end primarily due to the issuance of $900 million in long-term debt and a $189 million increase in deferred income taxes primarily driven by bonus tax depreciation enacted into law on July 4, 2025. These increases were partially offset by debt repayments of $613 million and a decrease in income and other taxes payable primarily resulting from payments of $429 million for previously postponed federal and state income taxes. Total shareholders' equity increased $653 million from prior year end primarily driven by net earnings of $2.9 billion, partially offset by share repurchases of $1.4 billion and dividends paid of $972 million.

**PART II**

Working capital is considered a measure of a company's ability to meet its short-term needs. CSX had a working capital deficit of $583 million at December 2025 and $456 million at December 2024. This deficit increase of $127 million since prior year end is primarily due to cash paid for property additions of $2.9 billion, share repurchases of $1.4 billion, dividend payments of $972 million, and debt repayments of $613 million. These decreases were partially offset by cash-generating net earnings of $4.9 billion and debt issued of $900 million.

The Company's working capital balance varies due to factors such as the timing of scheduled debt and tax payments and other changes in cash and cash equivalent balances. A working capital deficit is not unusual for CSX or other companies in the industry and does not indicate a lack of liquidity. The Company continues to maintain adequate current assets to satisfy current liabilities and maturing obligations when they come due. Furthermore, CSX has sufficient financial capacity, including its revolving credit facility, commercial paper program and its ability to file and use shelf registration statements to manage its day-to-day cash requirements and any anticipated obligations. The Company accesses the credit markets from time to time for additional liquidity.

***Credit Ratings***

Credit ratings reflect an independent agency's judgment on the likelihood that a borrower will repay a debt obligation at maturity. The ratings reflect many considerations, such as the nature of the borrower's industry and its competitive position, the size of the company, its liquidity and access to capital and the sensitivity of a company's cash flows to changes in the economy. The three largest rating agencies, Standard & Poor's Ratings Services ("S&P"), Moody's Investors Service ("Moody's"), and Fitch Ratings ("Fitch"), use alphanumeric codes to designate their ratings. The highest quality rating for long-term credit obligations is AAA for S&P and Fitch and is Aaa for Moody's. A credit rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency.

CSX's credit ratings remained stable during 2025 with no changes in the Company's S&P, Moody's, or Fitch ratings from prior year. The Company's credit ratings as of December 31, 2025 are summarized below:

---

| | | |
|:---|:---|:---|
| **Rating Agency** | **Long-Term Ratings** | **Outlook** |
| Fitch | A- | Stable |
| Moody's | A3 | Stable |
| S&P | BBB+ | Stable |

---

&nbsp;&nbsp;&nbsp;&nbsp;

The cost and availability of unsecured financing are materially affected by CSX's long-term credit ratings. Ratings of BBB- by S&P and Fitch and Baa3 by Moody's, or better, reflect ratings on debt obligations that fall within a band of credit quality considered to be investment-grade. If CSX's credit ratings were to decline to below investment-grade levels, the Company could experience significant increases in its interest cost for new debt. In addition, a decline in CSX's credit ratings to below investment-grade levels could adversely affect the market's demand, and thus the Company's ability to readily issue new debt. The Company is committed to maintaining an investment-grade credit profile.

**CONTRACTUAL OBLIGATIONS, OTHER COMMITMENTS AND OFF-BALANCE SHEET ARRANGEMENTS**

***Contractual Obligations***

CSX is party to contractual arrangements that obligate the Company to make future cash payments. These obligations impact the Company's liquidity and capital resource needs. The Company's contractual obligations primarily consist of long-term debt and related interest payments, purchase commitments, leases, other-post employment benefits and agreements with Conrail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• As of December 31, 2025, the Company had outstanding fixed-rate notes with varying maturities. See Note 10, *Debt and Credit Agreements*, for additional information related to future debt payments. Future interest payments associated with outstanding debt total $13.9 billion, with $831 million payable in 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Purchase commitments consist of CSX's long-term locomotive maintenance, rebuild and purchase program and other commitments to purchase technology, communications, railcar maintenance and other services. See Note 8, *Commitments and Contingencies*, for additional information about future payments related to purchase commitments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Capital expenditures include investments related to public-private partnerships. These partnership investments are typically for projects that are partially or wholly reimbursed to CSX through government awards or other funding sources. Project contribution commitments that are not reimbursable total $18 million as of December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company's leases include property, equipment, and line leases. See Note 7, *Leases*, for additional information about future payments related to leases.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Other post-employment benefits include estimated other post-retirement medical and life insurance payments and payments under non-qualified pension plans that are unfunded. See Note 9, *Employee Benefit Plans*, for additional information about future payments under such plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Conrail owns rail infrastructure and operates for the joint benefit of CSX and Norfolk Southern Corporation ("NS"). This is known as the shared asset area. Conrail charges fees for right-of-way usage, equipment rentals and transportation, switching and terminal service charges in the shared asset area. See Note 15, *Investment in Affiliates and Related-Party Transactions*, for additional information about future payments related to agreements with Conrail.

***Other Commitments and Off-Balance Sheet Arrangements***

Other commitments total $211 million and primarily consist of surety bonds, guarantees, and letters of credit, none of which are individually significant. These off-balance sheet arrangements are not reasonably likely to have a material effect on the Company's financial condition, results of operations or liquidity.

**LABOR AGREEMENTS**

Approximately 16,900 of the Company's approximately 23,000 employees are members of a rail labor union and covered by national agreements with the Class I railroads or CSX-specific agreements. As of the date of this filing, new agreements with an effective date of January 1, 2025, have been fully ratified by most unions, representing nearly 75% of the Company's unionized workforce. The remaining unionized employees are covered under previous agreements while negotiations take place since collective agreements under the Railway Labor Act do not expire, but continue until amended or replaced.

**CRITICAL ACCOUNTING ESTIMATES**

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that management make estimates in reporting the amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and certain revenues and expenses during the reporting period. Actual results may differ from those estimates. These estimates and assumptions are discussed with the Audit Committee of the Board of Directors on a regular basis. Significant estimates using management judgment are made for the following areas:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• personal injury and environmental reserves;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pension plan accounting; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• depreciation policies for assets under the group-life method

**Personal Injury and Environmental Reserves**

*Personal Injury*

Personal Injury reserves of $154 million and $142 million for 2025 and 2024, respectively, represent liabilities for employee work-related and third-party injuries. CSXT retains an independent actuary to assist management in assessing the value of personal injury claims. The methodology used by the actuary includes a development factor to reflect growth or reduction in the value of these personal injury claims. It is based largely on CSXT's historical claims and settlement experience. Actual results may vary from estimates due to the number, type and severity of the injury, costs of medical treatments and uncertainties in litigation. For additional details, including a description of our related accounting policies, see Note 5, *Casualty, Environmental and Other Reserves,* in the consolidated financial statements.

*Environmental*

Environmental reserves were $156 million and $151 million for 2025 and 2024, respectively. The Company is a party to various proceedings related to environmental issues, including administrative and judicial proceedings involving private parties and regulatory agencies. The Company has been identified as a potentially responsible party at approximately 220 environmentally impaired sites. The Company reviews its potential liability with respect to each site identified, giving consideration to a number of factors such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• type of clean-up required;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• nature of the Company's alleged connection to the location (e.g., generator of waste sent to the site or owner or operator of the site);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• extent of the Company's alleged connection (e.g., volume of waste sent to the location and other relevant factors); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• number, connection and financial viability of other named and unnamed potentially responsible parties at the location.

Conditions that are currently unknown could, at any given location, result in additional exposure, the amount and materiality of which cannot presently be reasonably estimated. For additional details, including a description of our related accounting policies, see Note 5, *Casualty, Environmental and Other Reserves,* in the consolidated financial statements.

**Pension Plan Accounting**

The Company sponsors defined benefit pension plans principally for salaried, management personnel. For employees hired prior to 2003, the plans provide eligible employees with retirement benefits based predominantly on years of service and compensation rates near retirement. For employees hired between 2003 and 2019, benefits are determined based on a cash balance formula, which provides benefits by utilizing interest and pay credits based upon age, service and compensation. Beginning in 2020, the CSX Pension Plan was closed to new participants. As of December 2025, the projected benefit obligation for the Company's pension plans was $2.2 billion*.* For information related to the funded status of the Company's pension plans, see Note 9, *Employee Benefit Plans*.

The accounting for these plans is subject to the guidance provided in the *Compensation-Retirement Benefits Topic* in the Accounting Standards Codification ("ASC"). This rule requires that management make certain assumptions relating to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• discount rates used to measure future obligations and interest expense;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• long-term rate of return on plan assets; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other assumptions.

The Company engages independent actuaries to compute the amounts of liabilities and expenses relating to these plans subject to the assumptions that the Company determines are appropriate based on historical trends, current market rates and future projections. These amounts are reviewed by management.

*Discount Rates*

Discount rates affect the amount of liability recorded and the service and interest cost components of pension expense. Discount rates reflect the rates at which pension benefits could be effectively settled, or in other words, how much it would cost the Company to buy enough high quality bonds to generate cash flow equal to the Company's expected future benefit payments. The Company determines the discount rate based on the market yield as of year-end for high quality corporate bonds whose maturities match the plans' expected benefit payments.

The Company measures the service and interest cost components of the net pension benefits expense by using individual spot rates matched with separate cash flows for each future year. Under the spot rate approach, individual spot discount rates along the same high quality corporate bonds yield curve used to measure the pension benefit liabilities are applied to the relevant projected cash flows at the relevant maturity.

The weighted average discount rate used by the Company to value its pension obligations was 5.25% and 5.50% as of December 2025, and December 2024, respectively. As of December 2025, the estimated duration of pension benefits is approximately 9 years.

Each year, the discount rate is reevaluated and adjusted using the current market interest rates for high quality corporate bonds to reflect the best estimate of the current effective settlement rates. In general, if interest rates decline or rise, the assumed discount rate will change.

**Critical Accounting Estimates,** *continued*

*Long-term Rate of Return on Plan Assets*

The expected long-term average rate of return on plan assets reflects the average rate of earnings expected on the funds invested, or to be invested, to provide for benefits included in the projected benefit obligation. In estimating that rate, the Company gives appropriate consideration to the historical returns earned by the plan assets in the funds, forward-looking economic assumptions, fees and other costs to be paid out of plan assets, and the current and projected asset mix of the funds. Management, with the assistance of an outsourced investment manager, balances market expectations obtained from various investment managers with both market and actual plan historical returns to develop a reasonable estimate of the expected long-term rate of return on assets. As this assumption is long term, the annual review may result in less frequent adjustment than other assumptions used in pension accounting. The long-term rate of return on plan assets used by the Company to value its benefit cost for the subsequent plan year was 6.25% and 6.75% in 2025 and 2024, respectively.

*Other Assumptions*

The calculations made by the actuaries also include assumptions relating to mortality rates, turnover, retirement age and salary inflation rates. These assumptions are based upon historical data, recent plan experience and industry trends and are determined by management.

*2026 Estimated Pension Expense*

Net periodic pension benefit expense for 2026 is expected to be a credit of $5 million. Net periodic pension benefit expense for 2026 is expected to include service cost expense of $21 million. Service cost expense is included in labor and fringe on the consolidated income statement and all other components of net pension expense are included in other income - net. Net periodic pension expense in 2025 was a credit of $8 million. The decrease in the expected credit is primarily due to a decrease in the expected return on plan assets.

The following sensitivity analysis illustrates the effects of a 1% change in certain assumptions on the 2026 estimated pension expense:

---

| | |
|:---|:---|
| *(Dollars in Millions)* | Pension Expense |
| Discount Rate | $11 |
| Long-term Rate of Return | $24 |

**Depreciation Policies for Assets Utilizing the Group-Life Method**

The depreciable assets of the Company are depreciated using either the group-life or straight-line method of accounting, which are both acceptable depreciation methods in accordance with GAAP. The Company depreciates its railroad assets, including main-line track, locomotives and freight cars, using the group-life method of accounting. Assets depreciated under the group-life method comprise 86% of total fixed assets of $53.8 billion on a gross basis at December 31, 2025. The remaining depreciable assets of the Company, including non-railroad assets and assets under finance leases, are depreciated using the straight-line method on a per asset basis. Land is not depreciated.

Management performs a review of depreciation expense, including the impacts of service lives and salvage values, on a regular basis. This review includes consideration of the most recent periodic depreciation studies, which are performed for assets depreciated using the group-life method. As part of the depreciation study, an assessment of the recorded amount of accumulated depreciation is made to determine if it is deficient (or in excess) of the appropriate amount indicated by the study. Any such deficiency (or excess), including any deferred gains or losses, is amortized as a component of depreciation expense over the remaining service life of the asset group until the next required depreciation study. There are several factors taken into account during the depreciation study and they include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statistical analysis of historical life and salvage data for each group of property;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statistical analysis of historical retirements for each group of property;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evaluation of current operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evaluation of technological advances and maintenance schedules;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• previous assessment of the condition of the assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• management's outlook on the future use of certain asset groups;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expected net salvage to be received upon retirement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• comparison of assets to the same asset groups with other companies.

The STB requires depreciation studies be performed every three years for equipment assets (e.g., locomotives and freight cars) and every six years for road and track assets (e.g., bridges, signals, rail, ties, and ballast). The Company reviews and evaluates asset service lives and salvage values for appropriateness at least annually, which includes consideration of the most recent depreciation studies or data reviews conducted by a third-party specialist. The most recent depreciation studies for equipment assets and road and track assets were performed in 2025 and 2020, respectively. Changes in the estimated service lives of assets and their related depreciation rates are implemented prospectively.

A 1% change in the average estimated useful life of all group-life assets would result in an approximate $15 million change to the Company's annual depreciation expense. There were no significant changes to the Company's asset lives as a result of the most recently completed studies prior to 2025. The Company does not expect any significant changes to asset lives as a result of the 2025 study, but does expect a favorable change to depreciation expense of approximately $40 million per year primarily as a result of increases in the remaining service lives of certain equipment assets. For additional details, including a more detailed description of our related accounting policies, see Note 6, *Properties,* in the consolidated financial statements.

**Item 7A. Quantitative and Qualitative Disclosures about Market Risk**

Changes in interest rates may impact the cost of future long-term debt issued by the Company, and as a result, represent interest rate risk to the Company. In an effort to manage this risk, CSX may use certain financial instruments such as interest rate forward contracts. The following information, together with information included in Note 10, *Debt and Credit Agreements*, and Note 13, *Fair Value Measurements*, describes the key aspects of such contracts and the related market risk to CSX.

Changes in interest rates could impact the fair value of the Company's fixed-to-floating interest rate swaps. In 2025, CSX entered into two fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to Secured Overnight Financing Rate ("SOFR") on a cumulative $250 million of fixed rate outstanding notes which are due in 2055. As of December 31, 2025, the fair value of these swaps was a $9 million asset. In 2023, CSX entered into two separate fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to the SOFR on a cumulative $250 million of fixed rate outstanding notes which are due in 2033. As of December 31, 2025, the cumulative fair value of these swaps was a $14 million asset. In 2022, CSX entered into five separate fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to SOFR on a cumulative $800 million of fixed rate outstanding notes, which are due between 2036 and 2040. As of December 31, 2025, the cumulative fair value of these swaps was a $87 million liability. As of December 31, 2025, the potential change in fair value of fixed-to-floating interest rate swaps resulting from a hypothetical 10% change in interest rates would not be material.

Changes in interest rates no longer impact the fair value of the Company's forward starting interest rate swaps because they were fully settled in 2024.

As of December 31, 2025, CSX had no floating rate notes outstanding. However, changes in interest rates could impact the fair value (but not the carrying value) of the Company's fixed rate long-term debt. The potential decrease in fair value of the Company's fixed rate long-term debt resulting from a hypothetical 10% increase in U.S. Treasury rates, or approximately 43 basis points, is estimated to be $757 million as of December 31, 2025, and $756 million as of December 31, 2024. The underlying fair values of the Company's long-term debt were estimated based on quoted market prices or on the current rates offered for debt with similar terms and maturities.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Shareholders and the Board of Directors of CSX Corporation

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of CSX Corporation (the Company) as of December 31, 2025 and 2024, the related consolidated income statements, comprehensive income statements, statements of changes in shareholders' equity and cash flow statements for each of the three years in the period ended December 31, 2025 and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 12, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matter**

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosure to which it relates.

| | ***Depreciation Policies for Assets Utilizing the Group-Life Method*** |
| *Description of the Matter* | As of December 31, 2025, assets depreciated under the group-life method comprised 86% of total gross fixed assets of $53.8 billion. As discussed in Note 6 of the consolidated financial statements, the group-life method aggregates assets with similar lives and characteristics into groups and depreciates each of these groups as a whole. When using the group-life method, an underlying assumption is that each group of assets, as a whole, is used and depreciated to the end of the group's recoverable life. The Company utilizes different depreciable asset categories to account for depreciation expense for the railroad assets that are depreciated under the group-life method.<br>Under the group-life method, depreciation studies are conducted by a third-party specialist and analyzed by the Company's management to review asset service lives and salvage values related to group-life assets. Depreciation studies are performed every three years for equipment assets and every six years for road and track assets. At least annually, management reviews and evaluates asset service lives and salvage values for appropriateness, which includes consideration of the most recent depreciation studies or data reviews conducted by a third-party specialist. For road and track assets and equipment assets, the most recent depreciation studies were performed in 2020 and 2025, respectively. <br>Auditing depreciation expense for assets subject to the group-life method was complex due to the nature of the methods used to determine the asset service lives and salvage values of the Company's assets. These methods have an impact on depreciation expense. |
| *How We Addressed the Matter in Our Audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's process to review asset service lives and salvage values related to group-life assets. For example, we tested controls over management's review of asset activity that could impact the estimated useful lives.<br>To test the asset service lives and salvage values of the Company's group-life assets, we performed audit procedures that included, among others: evaluating management's documentation to support its evaluation of asset service lives and salvage values to assess if there have been any indicators there has been a material change; evaluating the information provided by the Company's third-party specialist and reviewed by management; and assessing the completeness and accuracy of the data provided by management to the third-party specialist.<br>Additionally, we compared the assumptions used by management to those used throughout the industry and within other depreciation studies. We assessed the historical accuracy of management's estimates via retrospective review and independently recalculated the current year depreciation rates. |

*Lines of Business*

During 2025, the Company's services generated $14.1 billion of revenue and served four primary lines of business: merchandise, intermodal, coal and trucking.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The merchandise business shipped 2.6 million carloads (41% of volume) and generated $8.8 billion in revenue (62% of revenue) in 2025. The Company's merchandise business is comprised of shipments in the following diverse markets: chemicals, agricultural and food products, minerals, automotive, forest products, metals and equipment, and fertilizers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The intermodal business shipped 3.0 million units (48% of volume) and generated $2.1 billion in revenue (15% of revenue) in 2025. The intermodal business combines the superior economics of rail transportation with the flexibility of trucks and offers a cost and environmental advantage over long-haul trucking. Through a network of approximately 30 terminals, the intermodal business serves all major markets east of the Mississippi River and transports mainly manufactured consumer goods in containers, providing customers with truck-like service for longer shipments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The coal business shipped 718 thousand carloads (11% of volume) and generated $1.9 billion in revenue (13% of revenue) in 2025. The Company transports domestic coal, coke and iron ore to electricity-generating power plants, steel manufacturers and industrial plants as well as export coal to deep-water port facilities. Most of the export coal the Company transports is used for steelmaking, while the majority of domestic coal the Company ships is used for electricity generation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The trucking business generated $816 million, or 6%, of revenue in 2025. Trucking revenue is comprised of revenue from the operations of Quality Carriers.

Other revenue accounted for 4% of the Company's total revenue in 2025. This category includes revenue from regional subsidiary railroads and incidental charges, including intermodal storage and equipment usage, demurrage and switching. Revenue from regional subsidiary railroads includes shipments by railroads that the Company does not directly operate. Intermodal storage represents charges for customer storage of containers at an intermodal terminal, ramp facility or offsite location beyond a specified period of time. Demurrage represents charges assessed when freight cars are held by a customer beyond a specified period of time. Switching represents charges assessed when a railroad switches cars for a customer or another railroad.

*Segments*

The Company has two operating segments: rail and trucking. Although the Company provides a breakdown of revenue by line of business, the overall financial and operational performance of the railroad is analyzed as one operating segment due to the integrated nature of the rail network. The trucking segment is not material for separate disclosure. See Note 17, *Segment Reporting and Significant Expenses,* for additional information on the Company's segments.

*Employees*

The Company's number of employees was approximately 23,000 as of December 2025, which includes approximately 16,900 rail labor union employees. Most of the Company's employees provide or support transportation services.

**Item 8. Financial Statements and Supplementary Data**

**NOTE 1. Nature of Operations and Significant Accounting Policies,** *continued*

***Basis of Presentation***

In the opinion of management, the accompanying consolidated financial statements contain all normal, recurring adjustments necessary to fairly present the financial position of CSX and its subsidiaries at December 31, 2025, and December 31, 2024, and the consolidated statements of income, comprehensive income, cash flows and changes in shareholders' equity for the years ended 2025, 2024 and 2023. In addition, management has evaluated and disclosed all material events occurring subsequent to the date of the financial statements up to the date this annual report is filed on Form 10-K.

***Use of Estimates***

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that management make estimates in recording the amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amount of certain revenues and expenses during the reporting period. Actual results may differ from those estimates. Critical accounting estimates using management judgment are made for the following areas:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• personal injury and environmental reserves (see Note 5, *Casualty, Environmental and Other Reserves*);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pension plan accounting (see Note 9, *Employee Benefit Plans*); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• depreciation policies for assets under the group-life method (see Note 6, *Properties*)

***Fiscal Year***

The Company's fiscal periods are based upon the calendar year. Except as otherwise specified, references to full years indicate CSX's fiscal years ended on December 31, 2025, December 31, 2024, and December 31, 2023.

&nbsp;&nbsp;&nbsp;&nbsp;

***Principles of Consolidation***

The consolidated financial statements include results of operations of CSX and subsidiaries over which CSX has majority ownership or financial control. All significant intercompany accounts and transactions have been eliminated. Most investments in companies that were not majority-owned are accounted for under the equity method or as equity investments measured at cost and adjusted for observable price changes and impairment. These investments are reported within Investment in Affiliates and Other Companies on the consolidated balance sheets.

***Cash and Cash Equivalents***

On a daily basis, cash in excess of current operating requirements is invested in various highly liquid investments having a typical maturity date of three months or less at the date of acquisition. These investments are carried at cost, which approximates market value, and are classified as cash equivalents.

***Investments***

Investments in instruments with original maturities greater than three months that will mature in less than one year are classified as short-term investments. Investments with original maturities of one year or greater are initially classified within other long-term assets, and the classification is re-evaluated at each balance sheet date.

***Materials and Supplies***

Materials and supplies in the consolidated balance sheets are carried at average cost and consist primarily of parts used in the repair and maintenance of track structure, equipment, and CSXT's freight car and locomotive fleets, as well as fuel.

***New Accounting Pronouncements***

In December 2023, the FASB issued ASU 2023-09, *Improvements to Income Tax Disclosures*. This standard update requires additional interim and annual disclosures about a company's income taxes, including more detailed information around the annual rate reconciliation and income taxes paid. The Company adopted this guidance prospectively for this 2025 annual report filed on Form 10-K. This standard update did not impact the Company's results of operations or financial position as it only impacts disclosures. See Note 12, Income Taxes.

In November 2024, the FASB issued ASU 2024-03, *Disaggregation of Income Statement Expenses.* This standard update requires additional disclosures about certain expenses in commonly presented expense captions. The Company is required to adopt the guidance for its 2027 annual report filed on Form 10-K, though early adoption is permitted. The Company is currently evaluating the impact of these amendments on its disclosures, but this standard update will not impact the Company's results of operations or financial position.

In September 2025, the FASB issued ASU 2025-06, *Targeted Improvements to the Accounting for Internal-Use Software.* This standard update modernizes the capitalization criteria for internal-use software, eliminating references to project stages and instead requiring that projects meet completion probability criteria before costs can be capitalized. This guidance is effective beginning first quarter 2028, though early adoption is permitted, and can be applied using a prospective, retrospective, or modified transition approach. The Company is currently evaluating the impact of these amendments but does not anticipate that adoption will have a material impact on the Company's results of operations or financial position.

In December 2025, the FASB issued ASU 2025-10, *Accounting for Government Grants by Business Entities.* This standard establishes the accounting for government grants received by a business entity, including guidance for both grants related to an asset and grants related to income. This guidance is effective beginning first quarter 2029, though early adoption is permitted, and can be applied using a modified prospective, modified retrospective, or full retrospective transition approach. The Company is currently evaluating the impact of this guidance but does not anticipate that adoption will have a material impact on the Company's results of operations or financial position.

**NOTE 2. Earnings Per Share**

The following table sets forth the computation of basic earnings per share and earnings per share, assuming dilution:

---

|:---|:---|:---|:---|
| | **Years Ended** | **Years Ended** | **Years Ended** |
| | **2025** | 2024 | 2023 |

| &nbsp;&nbsp;&nbsp;Net Earnings | $**2889** | $3470 | $3668 |
| Denominator *(Units in Millions)*: |  |  |  |
| &nbsp;&nbsp;&nbsp;Average Common Shares Outstanding | **1870** | 1939 | 2008 |
| &nbsp;&nbsp;&nbsp;Other Potentially Dilutive Common Shares | **3** | 4 | 5 |
| &nbsp;&nbsp;&nbsp;Average Common Shares Outstanding, Assuming Dilution | **1873** | 1943 | 2013 |
| &nbsp;&nbsp;&nbsp;Net Earnings Per Share, Basic | $**1.54** | $1.79 | $1.83 |
| &nbsp;&nbsp;&nbsp;Net Earnings Per Share, Assuming Dilution | $**1.54** | $1.79 | $1.82 |

---

Basic earnings per share is based on the weighted-average number of shares of common stock outstanding. Earnings per share, assuming dilution, is based on the weighted-average number of shares of common stock outstanding and common stock equivalents adjusted for the effects of common stock that may be issued as a result of potentially dilutive instruments. CSX's potentially dilutive instruments are made up of equity awards including employee stock options, performance and restricted stock units.

When calculating diluted earnings per share, the potential shares that would be outstanding if all in-the-money outstanding stock options were exercised are included, net of shares CSX could repurchase using the proceeds from these hypothetical exercises. The total average outstanding equity awards that were excluded from the diluted earnings per share calculation because their effect was antidilutive is in the table below.

*Share Repurchase Programs*

During fourth quarter 2023, the Company began repurchasing shares under the $5 billion share repurchase program approved in October 2023. Total repurchase authority remaining was $1.2 billion as of December 31, 2025. The previous share repurchase program was announced in July 2022 and completed in November 2023.

Share repurchases may be made through a variety of methods including, but not limited to, open market purchases, purchases pursuant to Rule 10b5-1 plans, accelerated share repurchases and negotiated block purchases. The timing of share repurchases depends upon management's assessment of marketplace conditions and other factors, and the program remains subject to the discretion of the Board of Directors. Future share repurchases are expected to be funded by cash on hand, cash generated from operations and debt issuances. Shares are retired immediately upon repurchase. In accordance with the *Equity Topic* in the Accounting Standards Codification ("ASC"), the excess of repurchase price over par value is recorded in retained earnings.

*Share Repurchase Activity*

During 2025, 2024 and 2023, CSX repurchased the following shares:

---

| | | | |
|:---|:---|:---|:---|
| | **Years Ended** | **Years Ended** | **Years Ended** |
| | **2025** | 2024 | 2023 |

| &nbsp;&nbsp;&nbsp;Average Price Paid per Share | $**30.95** | $34.14 | $30.95 |
| &nbsp;&nbsp;Excise Taxes Paid for Net Share Repurchases <br>*(Dollars in Millions)* <sup>(a)</sup> | $**20** | $**33** | $— |

---

*(a) Excise tax payments made in 2025 were related to share repurchases in 2024. Excise tax payments made in 2024 were related to share repurchases in 2023.*

The Inflation Reduction Act of 2022 imposes a nondeductible 1% excise tax on the net value of most share repurchases made after December 31, 2022. Excise tax commensurate with net share repurchases is reflected in equity and a corresponding liability for excise taxes payable is included in other current liabilities on the consolidated balance sheet. The costs of shares repurchased shown in the table above exclude the impact of this excise tax.

| Preferred Shares Authorized | 25 |
| Preferred Shares Issued and Outstanding |  |

---

Holders of common stock are entitled to one vote on all matters requiring a vote for each share held. Preferred stock is senior to common stock with respect to dividends and upon liquidation of CSX.

**NOTE 4. Stock Plans and Share-Based Compensation**

Under CSX's share-based compensation plans, awards consist of performance units, stock options, and restricted stock units for management and stock grants for directors. Awards granted under the various programs are determined and approved by the Compensation and Talent Management Committee of the Board of Directors. Awards to the Chief Executive Officer are approved by the full Board and awards to senior executives are approved by the Compensation and Talent Management Committee. In certain circumstances, the Chief Executive Officer or delegate approves awards to management employees other than senior executives. The Board of Directors approves awards granted to CSX's non-management directors upon recommendation of the Governance and Sustainability Committee.

Share-based compensation expense for awards under share-based compensation plans and purchases made as part of the employee stock purchase plan is measured using the fair value of the award on the grant date and is recognized on a straight-line basis over the service period of the respective award. Alternatively, expense is recognized upon death or over an accelerated service period for employees whose agreements allow for continued vesting upon retirement or separation. Forfeitures are recognized as they occur. Total pre-tax expense and income tax benefits associated with share-based compensation are shown in the table below. Income tax benefits include impacts from option exercises and the vesting of other equity awards.

***Long-term Incentive Plans***

The objective of the CSX Long-term Incentive Plans ("LTIP") is to motivate and reward certain employees for achieving and exceeding certain financial goals. The 2025-2027, 2024-2026, and 2023-2025 LTIPs were adopted under the 2019 Stock and Incentive Award Plan.

*Performance Units*

In 2025, 2024 and 2023, target performance units, with each unit being equivalent to one share of CSX common stock, were granted to certain employees under three separate LTIP plans covering three-year cycles: the 2025-2027 ("2025-2027 LTIP"), the 2024-2026 ("2024-2026 LTIP"), and the 2023-2025 ("2023-2025 LTIP"). Payouts of performance units for the plans will be made in CSX common stock based on the achievement of certain goals, in each case excluding non-recurring items as disclosed in the Company's financial statements. The payout range for most participants will be between 0% and 200% of the target awards depending on Company performance against predetermined goals for each three-year cycle.

For the 2025, 2024 and 2023 awards, the average annual operating income growth percentage and Economic Profit (CSX Cash Earnings or CCE), in each case excluding non-recurring items as defined in the plan, will each comprise 50% of the payout and will be measured independently of the other. Participants will receive stock dividend equivalents declared over the performance period based on the number of performance units paid upon vesting. As defined under the plan, Economic Profit incentivizes strategic investments earning more than management's desired minimum required return and is calculated as CSX's gross cash earnings minus the capital charge on gross operating assets.

For these plans, payouts for certain executive officers are subject to formulaic upward or downward adjustment by up to 20% for the 2025-2027 LTIP or 25% for the 2024-2026 and 2023-2025 LTIPs, capped at an overall payout of 240% for the 2025-2027 LTIP or 250% for the 2024-2026 and 2023-2025 LTIPs, based upon the Company's total shareholder return relative to specified comparable groups over the performance period.

The fair values of the performance units granted during the years ended December 2025, 2024 and 2023 for awards with total shareholder return components were calculated using a Monte-Carlo simulation model. Performance unit grants were valued using the following weighted-average assumptions:

---

| | | | |
|:---|:---|:---|:---|
| | **Years Ended** | **Years Ended** | **Years Ended** |
| Weighted-Average Assumptions Used: | **2025** | 2024 | 2023 |
| Risk-free Interest Rate | **4.1%** | 4.4% | 4.4% |
| Annualized Volatility | **23.3%** | 23.3% | 33.2% |
| Expected Life *(in years)* | **2.7** | 2.9 | 2.8 |

---

The risk-free interest rate assumptions reflect the U.S. Treasury yield curve in effect at the time of grant. The annualized volatility is based on observed historical volatility of daily stock returns for the three-year period preceding the grant date. The expected life is calculated using the remainder of the performance period.

| Vested | (652) | 32.55 |
| Unvested at December 31, 2025 | 1154 | $36.10 |

---

As of December 2025, there was $10 million of total unrecognized compensation cost related to performance units that is expected to be recognized over a weighted-average period of approximately two years.

*Stock Options*

&nbsp;&nbsp;&nbsp;&nbsp;Stock options in 2025, 2024 and 2023 were primarily granted along with the corresponding LTIP plans. With these grants, an employee receives an award that provides the opportunity in the future to purchase CSX shares at the closing market price of the stock on the date the award is granted (the strike price). Options granted become exercisable in equal installments on the anniversary of the grant date over a vesting period (three-year graded). All options expire 10 years from the grant date if they are not exercised.

The fair value of stock options granted was estimated as of the dates of grant using the Black-Scholes option valuation model, which uses the following assumptions: dividend yield, risk-free interest rate, annualized volatility and expected life. The annual dividend yield is based on the most recent quarterly CSX dividend payment annualized. The risk-free interest rate is based on U.S. Treasury yield curve in effect at the time of grant. The annualized volatility is based on historical volatility of daily CSX stock price returns over a 6.0 year look-back period ending on the grant date. The expected life is calculated using the safe harbor approach due to lack of historical data on CSX options, which is the midpoint between the vesting schedule and contractual term (10 years).

**Other Awards**

Awards are periodically granted outside of the annual LTIP program, subject to approval by the Board of Directors, Compensation and Talent Management Committee, or Chief Executive Officer ("CEO") as appropriate. During 2025, 2024, and 2023, awards outside of the annual LTIP program were granted to certain management employees other than senior executives and were not material.

***Stock Awards for Directors***

CSX's non-management directors receive a base annual retainer of $130,000 to be paid quarterly in cash, unless the director chooses to defer the retainer in the form of cash or CSX common stock. Additionally, non-management directors receive an annual grant of common stock in the amount of approximately $190,000 and the independent non-executive Chairman also receives an annual grant of common stock in the amount of approximately $250,000. These awards are evaluated periodically by the Board of Directors.

***Employee Stock Purchase Plan***

In May 2018, shareholders approved the 2018 CSX Employee Stock Purchase Plan ("ESPP") for the benefit of Company employees. The Company registered 12 million shares of common stock that may be issued pursuant to this plan. Under the ESPP, employees may contribute between 1% and 10% of base compensation, after-tax, to purchase up to $25,000 of market value CSX common stock per year at 85% of the closing market price on either the grant date or the last day of the six-month offering period, whichever is lower. During 2025, 2024 and 2023, the Company issued the following shares under this program:

**NOTE 5. Casualty, Environmental and Other Reserves,** *continued*&nbsp;&nbsp;&nbsp;&nbsp;

These liabilities are accrued when probable and reasonably estimable in accordance with the *Contingencies Topic* in the ASC. Actual settlements and claims received could differ and final outcomes of these matters cannot be predicted with certainty. Considering the legal defenses currently available, the liabilities that have been recorded and other factors, it is the opinion of management that none of these items individually, when finally resolved, will have a material adverse effect on the Company's financial condition, results of operations or liquidity. Should a number of these items occur in the same period, however, their combined effect could be material in that particular period.

***Casualty***

Casualty reserves represent accruals for personal injury, occupational disease and occupational injury claims primarily related to railroad operations. The Company's self-insured retention amount for casualty claims is $100 million per occurrence as discussed in Note 8, *Commitments and Contingencies*. Currently, no individual claim is expected to exceed the self-insured retention amount. Most of the Company's casualty claims relate to CSXT. In accordance with the *Contingencies Topic* in the ASC, to the extent the value of an individual claim exceeds the self-insured retention amount, the Company would present the liability on a gross basis with a corresponding receivable for insurance recoveries.

These reserves fluctuate based upon the timing of payments as well as changes in estimate. Actual results may vary from estimates due to the number, type and severity of the injury, costs of medical treatments and uncertainties in litigation. Defense and processing costs, which historically have been insignificant and are anticipated to be insignificant in the future, are not included in the recorded liabilities. Changes in casualty reserves are included in purchased services and other on the consolidated income statements.

*Personal Injury*

Personal injury reserves represent liabilities for employee work-related and third-party injuries. Work-related injuries for CSXT employees are primarily subject to the Federal Employers' Liability Act ("FELA"). CSXT retains an independent actuary to assist management in assessing the value of personal injury claims. An analysis is performed by the actuary quarterly and is reviewed by management. The methodology used by the actuary includes a development factor to reflect growth or reduction in the value of these personal injury claims based largely on CSXT's historical claims and settlement experience. These analyses did not result in a material adjustment to the personal injury reserve in 2025, 2024 or 2023.

*Occupational*

Occupational reserves represent liabilities arising from allegations of exposure to certain materials in the workplace (such as solvents, soaps, chemicals and diesel fumes), past exposure to asbestos or allegations of chronic physical injuries resulting from work conditions (such as repetitive stress injuries). The Company retains an independent actuary to analyze the Company's historical claims, settlement amounts, and dismissal rates to assist in determining future anticipated claim filing rates and average settlement values. This analysis is performed by the actuary and reviewed by management quarterly. There were no material adjustments to the occupational reserve in 2025, 2024 or 2023.

***Environmental***

The Company is a party to various proceedings related to environmental issues, including administrative and judicial proceedings involving private parties and regulatory agencies. The Company has been identified as a potentially responsible party at approximately 220 environmentally impaired sites. Many of these are, or may be, subject to remedial action under the federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), also known as the Superfund Law, or similar state statutes. Most of these proceedings arose from environmental conditions on properties used for ongoing or discontinued railroad operations. A number of these proceedings, however, are based on allegations that the Company, or its predecessors, sent hazardous substances to facilities owned or operated by others for treatment, recycling or disposal. In addition, some of the Company's land holdings were leased to others for commercial or industrial uses that may have resulted in releases of hazardous substances or other regulated materials onto the property and could give rise to proceedings against the Company.

In any such proceedings, the Company is subject to environmental clean-up and enforcement actions under the Superfund Law, as well as similar state laws that may impose joint and several liability for clean-up and enforcement costs on current and former owners and operators of a site without regard to fault or the legality of the original conduct. These costs could be substantial.

**NOTE 5. Casualty, Environmental and Other Reserves,** *continued*

In accordance with the *Asset Retirement and Environmental Obligations Topic* in the ASC, the Company reviews its role with respect to each site identified at least quarterly, giving consideration to a number of factors such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• type of clean-up required;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• nature of the Company's alleged connection to the location (e.g., generator of waste sent to the site or owner or operator of the site);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• extent of the Company's alleged connection (e.g., volume of waste sent to the location and other relevant factors); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• number, connection and financial viability of other named and unnamed potentially responsible parties at the location.

Based on management's review process, amounts have been recorded to cover contingent anticipated future environmental remediation costs with respect to each site to the extent such costs are reasonably estimable and probable. The recorded liabilities for estimated future environmental costs are undiscounted. The liability includes future costs for remediation and restoration of sites as well as any significant ongoing monitoring costs, but excludes any anticipated insurance recoveries. Payments related to these liabilities are expected to be made over the next several years. Environmental remediation costs are included in purchased services and other on the consolidated income statements.

Currently, the Company does not possess sufficient information to reasonably estimate the amounts of additional liabilities, if any, on some sites until completion of future environmental studies. In addition, conditions that are currently unknown could, at any given location, result in additional exposure, the amount and materiality of which cannot presently be reasonably estimated. Based upon information currently available, however, the Company believes its environmental reserves accurately reflect the estimated cost of remedial actions currently required.

***Other***

Other reserves include liabilities for various claims, such as automobile, property, general liability, workers' compensation and longshoremen disability claims.

*Capital Expenditures*

The Company's capital investment includes purchased and self-constructed assets and property additions that substantially extend the service life or increase the utility of those assets. Indirect costs that can be allocated to capital projects are also capitalized. The Company is committed to maintaining and improving its existing infrastructure and expanding its network capacity for long-term growth. Rail operations are capital intensive and CSX accounts for these costs in accordance with United States generally accepted accounting principles ("GAAP") and the Company's capitalization policy. All properties are stated at historical cost less an allowance for accumulated depreciation.

The Company's largest category of capital investment is the replacement of track assets, which is primarily completed by CSXT employees, as well as the acquisition or construction of new assets that enable CSX to enhance its operations or provide new capacity offerings to its customers. Costs for track asset replacement and capacity projects that are capitalized include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• labor costs, because many of the assets are self-constructed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• costs to purchase or construct new track or to prepare ground for the laying of track;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• welding (rail, field and plant), which are processes used to connect segments of rail;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• new ballast, which is gravel and crushed stone that holds track in line;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fuels and lubricants associated with tie, rail and surfacing work, which is the process of raising track to a designated elevation over an extended distance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cross, switch and bridge ties, which are the braces that support the rails on a track;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• gauging, which is the process of standardizing the distance between rails;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• handling costs associated with installing rail, ties or ballast;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• usage charge of machinery and equipment utilized in construction or installation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other track materials.

Labor is a significant cost in self-constructed track replacement work. CSXT engineering employees directly charge their labor to the track replacement project (the capitalized depreciable property). In replacing track, these employees concurrently perform deconstruction and installation of track material. Because of this concurrent process, CSX must estimate the amount of labor that is related to deconstruction versus installation. As a component of the depreciation study for road and track assets, management performs an analysis of labor costs related to the self-constructed track replacement work, which includes direct observation of track replacement processes. Through this analysis, CSX determined that approximately 20% of labor costs associated with track replacement is related to the deconstruction of old track, for which certain elements are expensed, and approximately 80% is associated with the installation of new track, which is capitalized.

Capital investment related to locomotives and freight cars comprises the second largest category of the Company's capital assets. This category includes purchases of locomotives and freight cars as well as costs to modify or rebuild these assets, which are capitalized if the investment incurred extends the asset's service life or improves utilization. Improvement projects must meet specified dollar thresholds to be capitalized and are reviewed by management to determine proper accounting treatment. Routine repairs, overhauls and other maintenance costs, for all asset categories, are expensed as incurred.

**NOTE 6. Properties,** *continued*

*Depreciation Method*

The depreciable assets of the Company are depreciated using either the group-life or straight-line method of accounting, which are both acceptable depreciation methods in accordance with GAAP. The Company depreciates its railroad assets, including main-line track, locomotives and freight cars, using the group-life method. Assets depreciated under the group-life method comprise 86% of total fixed assets of $53.8 billion on a gross basis as of December 2025. The remaining depreciable assets of the Company, including non-railroad assets and assets under finance leases, are depreciated using the straight-line method on a per asset basis. Land is not depreciated.

The group-life method aggregates assets with similar lives and characteristics into groups and depreciates each of these groups as a whole. When using the group-life method, an underlying assumption is that each group of assets, as a whole, is used and depreciated to the end of its group's recoverable life. The Company currently utilizes different depreciable asset categories to account for depreciation expense for the railroad assets that are depreciated under the group-life method. By utilizing various depreciable categories, the Company can more accurately account for the use of its assets. The group-life method of depreciation closely approximates the straight-line method of depreciation. Additionally, due to the nature of most of its assets (e.g. track is one contiguous, connected asset), the Company believes that this is the most accurate and effective way to properly depreciate its assets. All assets of the Company are depreciated on a time or life basis.

*Depreciation Studies*

Management performs a review of depreciation expense, including the impacts of service lives and salvage values, on a regular basis. This review includes consideration of the most recent periodic depreciation studies, which are performed for assets depreciated using the group-life method. A depreciation study is the periodic review of asset service lives, salvage values, accumulated depreciation, and other related factors for group assets conducted by a third-party specialist, analyzed by the Company's management and approved by the Surface Transportation Board ("STB"), the regulatory board that has broad jurisdiction over railroad practices. The STB requires depreciation studies be performed every three years for equipment assets (e.g., locomotives and freight cars) and every six years for road and track assets (e.g., bridges, signals, rail, ties, and ballast). The Company believes the frequency of depreciation studies currently required by the STB, complemented by annual data reviews conducted by a third-party specialist and analyzed by the Company's management, provides adequate review of asset service lives and that a more frequent review would not result in a material change due to the long-lived nature of most of the assets.

The Company completed a depreciation study for its road and track assets in 2020, which resulted in changes to accumulated depreciation, service lives, salvage values, and other related factors for certain assets. The Company performed a depreciation study for equipment assets in 2025, with the resulting changes to be implemented after the study's finalization in 2026. The Company expects a favorable change to depreciation expense of approximately $40 million per year primarily as a result of increases in the remaining service lives of certain equipment assets. The Company plans to complete the next depreciation study for road and track assets in 2027.

*Group-Life Assets Sales and Retirements* 

Since the rail network is one contiguous, connected network, it is impractical to maintain specific identification records for these assets. For track assets (i.e., rail, ties, and ballast), CSX retires assets on a statistical curve relative to the age of the assets. Equipment assets (e.g., locomotives and freight cars) are specifically identified at retirement. When an equipment asset is retired that has been depreciated using the group-life method, the cost is reduced from the cost base and recorded in accumulated depreciation.

For sales or retirements of assets depreciated under the group-life method that occur in the ordinary course of business, the asset cost (net of salvage value or sales proceeds) is charged to accumulated depreciation and no gain or loss is immediately recognized. This practice is consistent with accounting treatment prescribed under the group-life method. As part of the depreciation study, an assessment of the recorded amount of accumulated depreciation is made to determine if it is deficient (or in excess) of the appropriate amount indicated by the study. Any such deficiency (or excess), including any deferred gains or losses, is amortized as a component of depreciation expense over the remaining service life of the asset group until the next required depreciation study. Since the overall assumption with the group-life method is that the assets within the group on average have the same service life and characteristics, it is therefore concluded that the deferred gains and losses offset over time.

For sales or retirements of assets depreciated under the group-life method that do not occur in the ordinary course of business, a gain or loss may be recognized if the sale or retirement meets each of the following three criteria: (i) it is unusual, (ii) it is material in amount, and (iii) it varies significantly from the retirement profile identified through depreciation studies. No material gains or losses were recognized on the sale of assets depreciated using the group-life method in 2025, 2024 or 2023, as no sales met the criteria described above.

*Land and Straight-line Assets Sales and Retirements* 

When the Company sells or retires land, land-related easements or assets depreciated under the straight-line method, a gain or loss is recognized in purchased services and other on the consolidated statements of income. The Company recognized gains on the sale of properties of $17 million, $11 million, and $34 million in 2025, 2024 and 2023, respectively.

*Impairment Review*

Properties and other long-lived assets are reviewed for impairment whenever events or business conditions indicate the carrying amount of such assets may not be fully recoverable. Initial assessments of recoverability are based on estimates of undiscounted future net cash flows associated with an asset or a group of assets. Where impairment is indicated, the assets are evaluated and their carrying amount is reduced to fair value based on discounted net cash flows or other estimates of fair value. Impairment of group-life assets in service is recorded to accumulated depreciation while impairment of straight-line assets is recorded in operating expense. Impairment expense recorded in purchased services and other expense on the consolidated income statement of $26 million in 2025, $24 million in 2024, and $2 million in 2023 was primarily due to the discontinuation of certain in-progress projects.

*Government Assistance*

The Company is a party to contracts with recipients and subrecipients of awards from federal, state and local governmental agencies. These awards are typically in the form of cash for purposes of making improvements to the rail network as part of public safety, corridor expansion or economic revitalization initiatives. The awarding agency generally specifies how the awards are to be spent by the recipients and may include limited conditions requiring return of the assistance.

Government funding received or receivable related to a property asset is netted with the cost of the asset in properties on the consolidated balance sheet, and the net asset is subject to depreciation. Any amounts owed by the government entity are recorded in accounts receivable until reimbursed. For the years ended 2025, 2024, and 2023, the total amounts received under contracts with government entities to improve the rail network was $216 million, $246 million, and $84 million, respectively. Non-freight accounts receivable related to these government projects was $121 million and $39 million as of December 31, 2025, and December 31, 2024, respectively.

**NOTE 7. Leases**

At inception, the Company determines if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. Some of the Company's lease arrangements contain lease components (e.g., minimum rent payments) and non-lease components (e.g., maintenance, labor charges, etc.). The Company generally accounts for each component separately based on the estimated standalone price of each component. For certain equipment leases, such as freight car, vehicles and work equipment, the Company accounts for the lease and non-lease components as a single lease component.

Certain of the Company's lease agreements include rental payments that are adjusted periodically for an index or rate. The leases are initially measured using the projected payments adjusted for the index or rate in effect at the commencement date. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants.

***Operating Leases***

Operating leases are included in right-of-use lease assets, other current liabilities and long-term lease liabilities on the consolidated balance sheets. These assets and liabilities are recognized at the commencement date based on the present value of remaining lease payments over the lease term, discounted using the Company's secured incremental borrowing rates or implicit rates, when readily determinable. Short-term operating leases, which have an initial term of 12 months or less, are not recorded on the balance sheet.

The Company has various lease agreements with other parties with terms up to 50 years, including a significant operating lease with the State of Georgia for approximately 137 miles of right-of-way with integral track assets for a term of 50 years with an annual 2.5% increase. Non-cancelable, long-term leases may include provisions for maintenance, options to purchase and options to extend the terms. These options are included in the lease term when it is reasonably certain that the option will be exercised. Lease expense for operating leases, including leases with escalations over their terms, is recognized on a straight-line basis over the lease term. Variable lease expense is recognized in the period in which the obligation for those payments is incurred. Lease expense is included in equipment and other rents on the consolidated income statements and is reported net of lease income. Lease income was not material to the results of operations for 2025, 2024 or 2023.

**NOTE 8. Commitments and Contingencies**

***Purchase Commitments***

In 2025, CSXT revised and expanded its long-term locomotive agreement with a third party. The new agreement contains commitments related to a long-term maintenance program that covers a portion of CSXT's fleet of locomotives, specific locomotive rebuilds and an agreement to purchase additional locomotives. The maintenance program costs are based on the maintenance cycle for each covered locomotive, which is determined by the asset's utilization and type. Expected future costs may change as required maintenance schedules are revised and locomotives are placed into or removed from active service. The rebuild program costs are based on the condition of locomotive units and the Company's plan for rebuilding existing locomotives. Under CSXT's current obligations, the maintenance agreement will expire no earlier than 2035 and CSXT is contractually committed to locomotive rebuilds through 2029. Additionally, CSXT is contractually obligated to purchase a total of 100 new locomotives between 2026 and 2028.

The following table summarizes CSXT's payments, including prepayments, for the long-term maintenance and rebuild program, which covers approximately 1,900 locomotives with payments based on active status during the period. The 2025 payment amount includes a $96 million prepayment for 2026 locomotive maintenance services, which is included in other current assets on the consolidated balance sheet, as well as $14 million for pre-owned locomotives received in 2025.

***Insurance***

The Company maintains insurance programs with substantial limits for property damage, including resulting business interruption, as well as casualty claims, which includes third-party liability. A certain amount of risk is retained by the Company on each insurance program. Under its property insurance program, the Company retains all risk up to $200 million per occurrence for losses from floods and named windstorms and up to $175 million per occurrence for other property losses. For casualty claims, the Company retains all risk up to $100 million per occurrence. CSX purchases insurance coverage above its full self-retention amounts and retains a percentage of risk at various layers as well. While the Company believes its insurance coverage is adequate, future claims could exceed existing insurance coverage or insurance may not continue to be available at commercially reasonable rates.

***Legal***

The Company is involved in litigation incidental to its business and is a party to a number of legal actions and claims, various governmental proceedings and private civil lawsuits, including, but not limited to, those related to fuel surcharge practices, tax matters, environmental and hazardous material exposure matters, FELA and labor claims by current or former employees, other personal injury or property claims and disputes and complaints involving certain transportation rates and charges. Some of the legal proceedings include claims for compensatory as well as punitive damages and others are, or are purported to be, class actions. While the final outcomes of these matters cannot be predicted with certainty, considering, among other things, the legal defenses available and liabilities that have been recorded along with applicable insurance, it is currently the opinion of management that none of these pending items is likely to have a material adverse effect on the Company's financial condition, results of operations or liquidity. An unexpected adverse resolution of one or more of these items, however, could have a material adverse effect on the Company's financial condition, results of operations or liquidity in that particular period.

**NOTE 8. Commitments and Contingencies,** *continued*

The Company is able to estimate a range of possible loss for certain matters for which a loss is reasonably possible in excess of reserves established. The Company has estimated this range to be $2 million to $72 million in the aggregate as of December 31, 2025. This estimated aggregate range is based upon currently available information and is subject to significant judgment and a variety of assumptions. Accordingly, the Company's estimate will change from time to time, and actual losses may vary significantly from the current estimate.

*Fuel Surcharge Antitrust Litigation*

In May 2007, class action lawsuits were filed against CSXT and three other U.S.-based Class I railroads alleging that the defendants' fuel surcharge practices relating to contract and unregulated traffic resulted from an illegal conspiracy in violation of antitrust laws. The class action lawsuits were transferred to federal court in the District of Columbia for coordinated or consolidated pre-trial proceedings. In 2017, the District Court issued its decision denying class certification. On August 16, 2019, the U.S. Court of Appeals for the D.C. Circuit affirmed the District Court's ruling.

Although the class was not certified, individual shippers have since brought claims against the railroads, which were also transferred to federal court in the District of Columbia for pre-trial proceedings but before a different judge. In March 2024, the original case was reassigned to the judge in the later-filed case. The railroads filed motions for summary judgment on July 17, 2024 with the briefing completed in December 2024. The judge held a hearing on the railroads' summary judgment motions on June 18, 2025, and granted summary judgment in favor of the railroads on June 24, 2025, ordering the cases closed. Most of the individual shippers have appealed the summary judgment ruling to the U.S. Court of Appeals for the D.C. Circuit, and briefing of the appeal is scheduled to conclude in April 2026.

*Environmental*

CSXT is indemnifying Pharmacia LLC, formerly known as Monsanto Company, ("Pharmacia") for certain liabilities associated with real estate located in Kearny, New Jersey along the Lower Passaic River (the "Property"). The Property, which was formerly owned by Pharmacia, is now owned by CSXT. CSXT's indemnification and defense duties arise with respect to several matters. The U.S. Environmental Protection Agency ("EPA"), using its CERCLA authority, seeks the investigation and cleanup of hazardous substances in the 17-mile Lower Passaic River Study Area (the "Study Area"). CSXT, on behalf of Pharmacia, and a significant number of other potentially responsible parties are together conducting a Remedial Investigation and Feasibility Study of the Study Area pursuant to an Administrative Settlement Agreement and Order on Consent with the EPA. Pharmacia's share of responsibility, indemnified by CSXT, for the investigation and cleanup costs of the Study Area may be determined through various mechanisms including (a) an allocation and settlement with EPA; (b) litigation brought by EPA against non-settling parties; or (c) litigation among the responsible parties.

For the lower eight miles of the Study Area, EPA issued its Record of Decision detailing the agency's mandated remedial process in March 2016. Occidental Chemical Corporation ("Occidental") performed the remedial design for the lower eight-mile portion of the Study Area pursuant to a consent order with EPA. EPA approved the design in May 2024.

For the remaining upper nine miles of the Study Area, EPA selected an interim remedy in a Record of Decision dated September 28, 2021. On March 2, 2023, EPA issued an administrative order requiring Occidental to design the interim remedy for the upper nine miles of the Study Area.

Potentially responsible parties, including Pharmacia, are participating in an EPA-directed allocation and settlement process to assign responsibility related to the lower river and the entire Study Area, respectively. CSXT participated in the EPA-directed allocation and settlement process on behalf of Pharmacia.

On March 2, 2022, EPA issued a Notice Letter to Pharmacia, Occidental and eight other parties alleging they are liable under Section 107(a) of CERCLA for releases or threatened releases of hazardous substances and requesting each party, individually or collectively, submit good faith offers to EPA in connection with the entire Study Area. CSXT, on behalf of Pharmacia, responded to the Notice Letter and submitted a good faith offer to EPA on June 27, 2022, following meetings with a mediator from EPA's Conflict Prevention and Resolution Center.

On November 21, 2023, EPA notified the United States District Court for the District of New Jersey ("Court") that it intended to move to enter a Consent Decree ("CD") with a group of potentially responsible parties. On January 31, 2024, EPA filed a motion to enter a modified CD with 82 potentially responsible parties, not including Pharmacia, requiring payment of $150 million to resolve their liability with respect to the entire Study Area. On April 1, 2024, Occidental filed its opposition to EPA's motion to enter the CD. Several other non-settling parties, including Pharmacia, filed comments concerning (but not opposing) entry of the CD. On December 18, 2024, the Court entered and approved the CD, which is now under appeal. Negotiations with EPA and other parties to resolve Pharmacia's liability continue.

On October 2, 2025, Occidental Petroleum Corporation announced a definitive agreement for Berkshire Hathway to acquire Occidental's chemical business, which had been separated into its own entity as a result of Occidental having completed a divisive merger under Texas law that divided its overall business into two entities. Occidental Chemical Corporation, a Texas corporation ("New Occidental"), now holds the company's manufacturing assets, while Environmental Resource Holdings, also a Texas corporation ("ERH"), holds legacy environmental liabilities, including those related to the Lower Passaic River. This transaction, through which Occidental Petroleum Corporation sold all equity interests in New Occidental to Berkshire Hathaway, closed on January 2, 2026. On February 6, 2026, a group of parties, including Pharmacia, filed a complaint in New Jersey federal court seeking a declaratory judgment that New Occidental remains jointly and severally liable with ERH for CERCLA liability related to the Lower Passaic River.

CSXT is also defending and indemnifying Pharmacia with regard to the Property in litigation filed by Occidental, which is seeking to recover its past and future costs associated with the remediation of the entire Study Area. Alternatively, Occidental seeks to compel some, or all, of the defendants to participate in the remediation of the Study Area. Pharmacia is one of approximately 110 defendants in a federal lawsuit filed by Occidental on June 30, 2018, and one of 37 defendants in a federal lawsuit filed by Occidental on March 24, 2023. Both of these lawsuits are stayed pending resolution of the CD action. CSXT is also defending and indemnifying Pharmacia in a cooperative natural resource damages assessment process related to the Property.

Based on currently available information, the Company does not believe its share of remediation costs as determined by the EPA-directed allocation with respect to the Property and the Study Area would be material to the Company's financial condition, results of operations or liquidity.

See Note 5, Casualty, Environmental and Other Reserves, for additional information on the Company's environmental liabilities.

*Regulatory*

In October 2024, the Company received a subpoena from the Enforcement Division of the U.S. Securities and Exchange Commission ("SEC") requesting information related to, among other things, the accounting restatement disclosed in the Company's Form 10-Q for the quarterly period ended June 30, 2024 filed on August 5, 2024 with the SEC. The Company has also been responding to information requests by the SEC related to certain of the Company's non-financial performance metrics. The Company received correspondence from the SEC on July 10, 2025, indicating that the agency had concluded its investigation and does not intend to recommend an enforcement action.

**NOTE 9. Employee Benefit Plans**

The Company sponsors defined benefit pension plans principally for salaried, management personnel. For employees hired prior to 2003, the plans provide eligible employees with retirement benefits based predominantly on years of service and compensation rates near retirement. For employees hired between 2003 and 2019, benefits are determined based on a cash balance formula, which provides benefits by utilizing interest and pay credits based upon age, service and compensation. The CSX Pension Plan, the largest plan based on benefit obligation, was closed to new participants in 2020.

The Company engages independent actuaries to compute the amounts of liabilities and expenses relating to these plans subject to the assumptions that the Company determines are appropriate based on historical trends, current market rates and future projections. These amounts are reviewed by management. In order to perform this valuation, the actuaries are provided with the details of the population covered at the beginning of the year, summarized in the table below, and projects that population forward to the end of the year.

**NOTE 9. Employee Benefit Plans,** *continued*

The benefit obligation for these plans represents the liability of the Company for current and former employees and is affected primarily by the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• service cost (benefits attributed to employee service during the period);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• interest cost (interest on the liability due to the passage of time);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actuarial gains/losses (experience during the year different from that assumed and changes in plan assumptions); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• benefits paid to participants.

***Cash Flows***

Plan assets are amounts that have been segregated and restricted to provide qualified pension plan benefits and include amounts contributed by the Company and amounts earned from invested contributions, net of benefits paid. Qualified pension plan obligations are funded in accordance with regulatory requirements and with an objective of meeting or exceeding minimum funding requirements necessary to avoid restrictions on flexibility of plan operation and benefit payments. The Company funds the cost of nonqualified pension benefits on a pay-as-you-go basis. No qualified pension plan contributions were made during 2025, 2024 and 2023. No contributions to the Company's qualified pension plans are expected in 2026.

&nbsp;&nbsp;&nbsp;&nbsp;Future expected benefit payments are as follows:

***Plan Assets***

The Company outsources investment management related to pension plan assets. The CSX Investment Committee (the "Investment Committee"), whose members are selected by the Executive Vice President and Chief Financial Officer, is responsible for setting policy and oversight of investment management. The Investment Committee and investment manager utilize an investment asset allocation strategy that is monitored on an ongoing basis and updated periodically in consideration of plan or employee changes, or changing market conditions. Periodic studies provide an extensive modeling of asset investment return in conjunction with projected plan liabilities and seek to evaluate how to maximize return within the constraints of acceptable risk.

The current asset allocation targets 30% growth-oriented investments and 70% immunizing investments. The growth-oriented portfolio consists of return-seeking investments that are diversified across geography, market capitalization, and asset class. The immunizing portfolio is comprised of a customized mix of fixed income and cash investments designed to reduce liability risk. Allocations are evaluated for levels within 5% of targeted allocations and are adjusted quarterly as necessary.

Under the supervision of the Investment Committee, the investment manager selects investments or fund managers in accordance with standards of prudence applicable to asset diversification and investment suitability. The Company also selects fund managers with differing investment styles and benchmarks their investment returns against appropriate indices. Fund investment performance is continuously monitored. Acceptable performance is determined in the context of the long-term return objectives of the fund and appropriate asset class benchmarks.

Within the Company's equity funds, domestic stock is diversified among large and small capitalization stocks. International stock is diversified in a similar manner as well as in developed versus emerging markets stocks. Guidelines established with individual managers can limit investment by industry sectors, individual stock issuer concentration and the use of derivatives and CSX securities.

Fixed income securities guidelines established with individual managers specify the types of allowable investments, such as government, corporate and asset-backed bonds, target certain allocation ranges for domestic and foreign investments and limit the use of certain derivatives. Additionally, guidelines stipulate minimum credit quality constraints and any prohibited securities.

For qualified plan funding purposes, assets and discounted liabilities are measured in accordance with the Employee Retirement Income Security Act ("ERISA"), as well as other related provisions of the Internal Revenue Code and related regulations. Under these funding provisions and the alternative measurements available thereunder, the Company estimates its unfunded obligation for qualified plans on an annual basis.

The Company has recognized the funded status of a pension plan by recording a liability (underfunded plan) or asset (overfunded plan) for the difference between the projected benefit obligation and the fair value of plan assets at the plan measurement date. Amounts related to pension benefits recorded in other long-term assets, labor and fringe benefits payable and other long-term liabilities on the balance sheet are as follows:

Long-term assets as of December 2025 and 2024 in the preceding table relate to qualified pension plans where assets exceed projected benefit obligations. Current and long-term liabilities relate to plans where projected benefits obligations exceed assets. The Company's only plan with a net liability status is the unfunded non-qualified pension plan, which has no plan assets. This plan had a projected benefit obligation of $186 million and $186 million and an accumulated benefit obligation of $179 million and $178 million, as of December 31, 2025 and 2024, respectively.

***Assumptions***

The expected long-term average rate of return on plan assets reflects the average rate of earnings expected on the funds invested, or to be invested, to provide for benefits included in the projected benefit obligation. In estimating that rate, the Company gives appropriate consideration to the historical returns earned by the plan assets in the funds, forward-looking economic assumptions, fees and other costs to be paid out of plan assets, and the current and projected asset mix of the funds. Management, with the assistance of the outsourced investment manager, balances market expectations obtained from various investment managers with both market and actual plan historical returns to develop a reasonable estimate of the expected long-term rate of return on assets. This assumption is reviewed annually and adjusted as deemed appropriate.

The Company measures the service cost and interest cost components of the net pension benefits expense by using individual spot rates matched with separate cash flows for each future year. The weighted averages of assumptions used by the Company to value its pension obligations were as follows:

---

| | | |
|:---|:---|:---|
| | **Pension Benefits** | **Pension Benefits** |
| | **2025** | 2024 |
| Expected Long-term Return on Plan Assets: |  |  |

***Post-retirement Medical Plan***

In addition to these plans, the Company sponsors an unfunded post-retirement medical plan and a life insurance plan that provide certain benefits to full-time, salaried, management employees hired prior to 2003 upon their retirement if certain eligibility requirements are met. The accumulated post-retirement benefit obligation related to this plan was $46 million and $49 million, respectively, as of December 31, 2025 and 2024. Through 2034, total future expected benefit payments related to this plan were $42 million. Expenses in 2025, 2024 and 2023 related to this plan were not material.

***Other Plans***

The Company maintains savings plans for virtually all full-time salaried employees and certain employees covered by collective bargaining agreements. Expense associated with these plans was $39 million, $40 million and $35 million for 2025, 2024 and 2023, respectively, and is included in labor and fringe expense on the consolidated income statement.

Under collective bargaining agreements, the Company participates in a multi-employer benefit plan, which provides certain post-retirement health care and life insurance benefits to eligible contract employees. Premiums under this plan are expensed as incurred and were not material in 2025, 2024 or 2023.

Under the terms of collective bargaining agreements that cover union-represented employees, Quality Carriers contributes to two multi-employer pension plans. These plans provide defined benefits to retired participants. Both of these pension plans are in Pension Protection Act zone "red", meaning they are at least 65% underfunded. Formal rehabilitation plans have been adopted. Based on information provided to the Company from the administrators of these plans, Quality Carriers' portion of the contingent liability in the event of a full withdrawal or termination from these plans is estimated to be $284 million. Of this amount, $280 million relates to the Central States Southeast and Southwest Areas Pension Plan and is based on information as of December 31, 2024, which is the latest information available at the date the financial statements were issued. The Company does not currently intend to withdraw from any of these multi-employer pension plans. Required monthly contributions to these plans are not material.

***Interest Rate Derivatives***

*Fair Value Hedges*

In first quarter 2025, CSX entered into two fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to the Secured Overnight Financing Rate ("SOFR") on a cumulative $250 million of fixed rate outstanding notes which are due in 2055. The cumulative fair value of these swaps, which is included in other long-term assets on the consolidated balance sheet, was an asset of $9 million as of December 31, 2025.

CSX has seven other fixed-to-floating interest rate swaps classified as fair value hedges. The swaps are designed to hedge 10 years of interest rate risk associated with market fluctuations attributable to SOFR on a cumulative $1.1 billion of fixed rate outstanding notes which are due between 2032 and 2040. These swaps are comprised of two swaps entered during 2023 ("2023 swaps") and five swaps entered during 2022 ("2022 swaps"). The cumulative fair value of the 2023 swaps was an asset of $14 million and $7 million as of December 31, 2025, and December 31, 2024, respectively, and is included in other long-term assets on the consolidated balance sheet. The cumulative fair value of the 2022 swaps was a liability of $87 million and $123 million as of December 31, 2025, and December 31, 2024, respectively, and is included in other long-term liabilities on the consolidated balance sheet.

The swaps expire between 2032 and 2055. If settled early, the remaining cumulative fair value adjustment to the hedged notes will be amortized over the remaining life of the associated notes. The cumulative adjustment to the hedged notes is included in long-term debt on the consolidated balance sheet as shown in the table below.

Gains and losses resulting from changes in fair value of the interest rate swaps offset changes in the fair value of the hedged portion of the underlying debt with no gain or loss recognized due to hedge ineffectiveness.

*Cash Flow Hedges*

The Company had forward starting interest rate swaps, classified as cash flow hedges, that had an aggregate notional value of $500 million at inception. These swaps were effected to hedge the benchmark interest rate associated with future interest payments related to the anticipated refinancing of $850 million of 3.25% notes due in 2027. In accordance with the *Derivatives and Hedging Topic* in the ASC, the Company has designated these swaps as cash flow hedges. Under the terms of the Adjustable Interest Rate (LIBOR) Act, the reference rate on the swaps were automatically replaced with daily compounded SOFR plus the fallback spread on July 1, 2023, the LIBOR replacement date.

The Company executed settlements of $114 million and $226 million of the aggregate $500 million notional value of cash flow hedges in 2024 and 2023, respectively. These settlements resulted in CSX receiving cash payments of $52 million in 2024 and $95 million in 2023, which are included in other operating activities on the consolidated cash flow statement. A partial settlement also took place in 2022. As of December 31, 2025, and December 31, 2024, no unsettled aggregate notional value of these swaps remained and there was no related asset or liability.

Unrealized gains or losses associated with changes in the fair value of the hedge are recorded net of tax in accumulated other comprehensive income ("AOCI") on the consolidated balance sheet. As these swaps were fully settled in 2024, subsequent gains or losses are attributable to tax effects. The unrealized gain associated with the settled portion of the hedges will continue to be classified in AOCI until the associated debt instrument is issued in the future. The unrealized gain or loss in AOCI will be recognized in earnings as an adjustment to interest expense over the same period during which the hedged transaction affects earnings. Unrealized amounts related to the hedge, recorded net of tax in other comprehensive income, are summarized in the table below.

***Credit Facilities***

The Company has a $1.2 billion unsecured, revolving credit facility backed by a diverse syndicate of banks. This facility allows same-day borrowings at floating interest rates, based on SOFR or an agreed-upon replacement reference rate, plus a spread that depends upon CSX's senior unsecured debt ratings. This facility expires in February 2028. As of December 31, 2025, the Company had no outstanding balances under this facility.

Commitment fees and interest rates payable under the facility were similar to fees and rates available to comparably rated investment-grade borrowers. As of December 31, 2025, CSX was in compliance with all covenant requirements under the facility.

***Commercial Paper***

Under its commercial paper program, which is backed by the revolving credit facility, the Company may issue unsecured commercial paper notes up to a maximum aggregate principal amount of $1.0 billion. Proceeds from issuances of the notes are expected to be used for general corporate purposes. At December 31, 2025, the Company had no commercial paper outstanding.

***Revenue Recognition***

The Company generates revenue from rail freight billings under contracts with customers generally on a rate per carload, container or ton-basis based on length of haul and commodities carried. The Company's performance obligation arises when it receives a bill of lading ("BOL") to transport a customer's commodities at a negotiated price contained in a transportation services agreement or a publicly disclosed tariff rate. Once a BOL is received, a contract is formed whereby the parties are committed to perform, collectability of consideration is probable and the rights of the parties, shipping terms and conditions, and payment terms are identified. A customer may submit several BOLs for transportation services at various times throughout a service agreement term, but each shipment represents a distinct service that is a separately identified performance obligation.

CSX 2025 Form 10-K p.98

**CSX CORPORATION**

**PART II**

**Item 8. Financial Statements and Supplementary Data**

**NOTE 11. Revenues,** *continued*

The average transit time to complete a rail shipment is between 2 to 7 days depending on market. Payments for transportation services are normally billed once a BOL is received and are generally due within 15 days after the invoice date. The Company recognizes revenue over transit time of freight as it moves from origin to destination. Revenue for services started but not completed at the reporting date is allocated based on the relative transit time in each reporting period, with the portion allocated for services subsequent to the reporting date considered remaining performance obligations.

The certain key estimates included in the recognition and measurement of revenue and related accounts receivable are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenue associated with shipments in transit, which is recognized ratably over transit time and is based on average cycle times to move commodities and products from their origin to their final destination or interchange;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjustments to revenue for billing corrections and billing discounts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjustments to revenue for overcharge claims filed by customers, which are based on historical payments to customers for rate overcharges as a percentage of total billing; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Incentive-based refunds to customers, which are primarily volume-related, are recorded as a reduction to revenue on the basis of the projected liability (this estimate is based on historical activity, current volume levels and forecasted future volume).

Revenue related to interline transportation services that involve the services of another party, such as another railroad, is reported on a net basis. The portion of the gross amount billed to customers that is remitted by the Company to another party is not reflected as revenue.

Trucking revenue includes revenue from the operations of Quality Carriers and is mostly comprised of truck shipments of chemicals. A performance obligation arises when Quality Carriers receives a customer order to transport a commodity at a contracted rate. Revenue is recorded on a gross basis ratably over transit time.

Other revenue is recorded upon completion of the service and is comprised of revenue from regional subsidiary railroads and incidental charges, including demurrage, intermodal storage and equipment usage, and switching. Revenue from regional subsidiary railroads includes shipments by railroads that the Company does not directly operate. Demurrage represents charges assessed when freight cars are held by a customer beyond a specified period of time. Intermodal storage represents charges for customer storage of containers at an intermodal terminal, ramp facility or offsite location beyond a specified period of time. Switching represents charges assessed when a railroad switches cars for a customer or another railroad.

During 2025, 2024 and 2023, revenue recognized from performance obligations related to prior periods was not material.

***Remaining Performance Obligations***

Remaining performance obligations represent the transaction price allocated to future reporting periods for freight services started but not completed at the reporting date. This includes the unearned portion of billed and unbilled amounts for cancellable freight shipments in transit. The Company expects to recognize the unearned portion of revenue for freight services in transit within one week of the reporting date. As of December 31, 2025, remaining performance obligations were not material.

***Contract Balances and Accounts Receivable***

The timing of revenue recognition, billings and cash collections results in accounts receivable and customer advances and deposits (contract liabilities) on the consolidated balance sheets. Contract assets, contract liabilities and deferred contract costs recorded on the consolidated balance sheet as of December 31, 2025, and December 31, 2024, were not material.

The Company's accounts receivable - net consists of freight and non-freight receivables, reduced by an allowance for credit losses.

Freight receivables include amounts earned, billed and unbilled, and currently due from customers for transportation-related services. Non-freight receivables include amounts billed and unbilled and currently due related to non-revenue receivables, including government reimbursement receivables. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that will not be collected. The allowance is based upon an assessment of risk characteristics, historical payment experience, and the age of outstanding receivables adjusted for forward-looking economic conditions as necessary. Credit losses recognized on the Company's accounts receivable were not material in 2025 and 2024.

The Company files a consolidated federal income tax return, which includes its principal domestic subsidiaries. CSX and its subsidiaries are subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. CSX participated in a contemporaneous IRS audit of tax years 2025, 2024 and 2023. Federal examinations of original federal income tax returns for all years through 2023 are resolved.

As of December 2025 and 2024, the Company had approximately $21 million and $20 million, respectively, of total unrecognized tax benefits as a result of uncertain tax positions. Net tax benefits of $16 million and $16 million as of December 2025 and 2024, respectively, could favorably impact the effective income tax rate in each year. The Company does not expect that unrecognized tax benefits as of December 2025 for various state and federal income tax matters will significantly change over the next 12 months. The final outcome of these uncertain tax positions is not yet determinable. There were no material changes to the total gross unrecognized tax benefits and prior year audit resolutions of the Company during the years ended 2025, 2024, or 2023.

&nbsp;&nbsp;&nbsp;&nbsp;

CSX's continuing practice is to recognize net interest and penalties related to income tax matters in income tax expense. Accrued interest and penalties were not material as of December 2025 or 2024. Additionally, expenses from changes to the reserves for interest and penalties were not material in 2025, 2024, or 2023.

**NOTE 13. Fair Value Measurements**

The *Financial Instruments Topic* in the ASC requires disclosures about fair value of financial instruments in annual reports as well as in quarterly reports. For CSX, this statement applies to certain investments, pension plan assets, long-term debt and interest rate derivatives. The *Fair Value Measurements and Disclosures Topic* in the ASC clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value, including on a non-recurring basis, and requires additional disclosures about the use of fair value measurements.

Various inputs are considered when determining the value of the Company's investments, pension plan assets, long-term debt, interest rate derivatives and long-lived assets. The inputs or methodologies used for valuing financial instruments are not necessarily an indication of the risk associated with investing in these financial instruments. These inputs are summarized in the three broad levels listed below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1 – observable market inputs that are unadjusted quoted prices for identical assets or liabilities in active markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2 – other significant observable inputs (including quoted prices for similar securities, interest rates, credit risk, etc.); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3 – significant unobservable inputs (including the Company's own assumptions about the assumptions market participants would use in determining the fair value of investments).

The valuation methods described below may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

The Company's investment assets are carried at fair value on the consolidated balance sheet in accordance with the *Fair Value Measurements and Disclosures Topic* in the ASC. They are valued with assistance from a third-party trustee and consist of exchange-traded funds, corporate bonds, asset-backed securities, government securities, and short-term time deposits. The exchange-traded funds are valued at quoted market prices determined in an active market, which are Level 1 inputs. The corporate bonds, asset-backed securities and government securities are valued using broker quotes that utilize observable market inputs, which are Level 2 inputs. The carrying amount of time deposits as reported in the consolidated balance sheet, using Level 2 inputs, approximate fair value due to their short-term nature. Unrealized gains and losses as of December 31, 2025 and December 31, 2024 were not material. The Company believes any impairment of investments held with gross unrealized losses to be temporary and not the result of credit risk.

***Long-term Debt***

Long-term debt, which includes finance leases, is reported at carrying amount on the consolidated balance sheets and is the Company's only financial instrument with fair values significantly different from their carrying amounts. The majority of the Company's long-term debt is valued with assistance from a third party that utilizes closing transactions, market quotes or market values of comparable debt. For those instruments not valued by the third party, the fair value has been estimated by applying market rates of similar instruments to the scheduled contractual debt payments and maturities. These market rates are provided by the same third party. All of the inputs used to determine the fair value of the Company's long-term debt are Level 2 inputs.

The fair value of outstanding debt fluctuates with changes in a number of factors. Such factors include, but are not limited to, interest rates, market conditions, credit ratings, values of similar financial instruments, size of the instrument, cash flow projections and comparable trades. Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued. The fair value of a company's debt is a measure of its current value under present market conditions. It does not impact the financial statements under current accounting rules.

The fair value and carrying value of the Company's long-term debt is as follows:

---

| | | |
|:---|:---|:---|
| *(Dollars in Millions)* | **December 2025** | December 2024 |
| Long-term Debt (Including Current Maturities): |  |  |
| Fair Value | $**17305** | $16481 |
| Carrying Value | **18873** | 18503 |

---

***Interest Rate Derivatives***

The Company's fixed-to-floating interest rate swaps are carried at their respective fair values, which are determined with assistance from a third party based upon pricing models using inputs observed from actively quoted markets. All of the inputs used to determine the fair value of the fixed-to-floating interest rate swaps are Level 2 inputs. The fair value of the Company's fixed-to-floating interest rate swaps was an asset of $23 million and $7 million (for swaps entered in 2023 and 2025) and a liability of $87 million and $123 million (for swaps entered in 2022) as of December 31, 2025 and December 31, 2024, respectively.

Changes in interest rates no longer impact the fair value of the Company's forward starting interest rate swaps because they are fully settled as of December 31, 2025. See Note 10, *Debt and Credit Agreements,* for further information.

***Pension Plan Assets***

&nbsp;&nbsp;&nbsp;&nbsp;Pension plan assets are reported at fair value, net of pension liabilities, on the consolidated balance sheet. See Note 9, *Employee Benefit Plans,* for further information. There are several valuation methodologies used for those assets as described below.

*Investments in the Fair Value Hierarchy*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Common stock and Exchange-Traded Funds (Level 1):* Valued at the closing price reported on the active market on which the securities are traded on the last day of the year and classified in Level 1 of the fair value hierarchy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Mutual funds (Level 1*): Valued at the net asset value of shares held at year end based on quoted market prices determined in an active market. These assets are classified in Level 1 of the fair value hierarchy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Cash and cash equivalents (Level 1)*: Includes cash and short-term investments with an original maturity of three months or less. The carrying value of cash and cash equivalents at year end approximates fair value. These assets are classified in Level 1 of the fair value hierarchy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Corporate bonds, government securities, asset-backed securities and derivatives (Level 2)*: Valued using price evaluations reflecting the bid and/or ask sides of the market for a similar investment at year end. Asset-backed securities include commercial mortgage-backed securities and collateralized mortgage obligations. These assets are classified in Level 2 of the fair value hierarchy.

*Investments Measured at Net Asset Value*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Partnerships:* Net asset value of private equity is based on the fair market values associated with the underlying investments at year end. These funds have varying redemption restrictions, but most require advanced notice of at least 15 business days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Commingled and common collective trust funds:* This class consists of private funds that invest in corporate equity and debt securities, government securities and various short-term debt instruments and are measured at net asset value to estimate the fair value of the investments. The net asset value of the investments is determined by reference to the fair value of the underlying securities, which are valued primarily through the use of directly or indirectly observable inputs. These funds have redemption restrictions that require advanced notice of up to 45 business days.

**NOTE 14. Other Income - Net**

The Company derives income from items that are not considered operating activities. Income from these items is reported net of related expense. All components of net periodic pension and post-retirement benefit costs, excluding service cost, are included in other income - net on the consolidated income statement. Miscellaneous income (expense) may fluctuate due to timing and includes investment gains and losses, interest income and other non-operating activities.

For more information about the drivers of changes in net periodic pension and post-retirement benefit credit from 2024 to 2025 and from 2023 to 2024, refer to Note 9, *Employee Benefit Plans*. Interest income decreased from 2024 to 2025 primarily as a result of lower average investment balances. Interest income increased from 2023 to 2024 primarily as a result of higher average interest rates. Other income – net consisted of the following:

***Conrail***

Through a limited liability company, CSX and Norfolk Southern Corporation ("NS") jointly own Conrail. CSX has a 42% economic interest and 50% voting interest in the jointly-owned entity, and NS has the remainder of the economic and voting interests. Pursuant to the *Investments-Equity Method and Joint Venture Topic* in the ASC, CSX applies the equity method of accounting to its investment in Conrail.

Conrail owns rail infrastructure and operates for the joint benefit of CSX and NS. This is known as the shared asset area. Conrail charges fees for right-of-way usage, equipment rentals and transportation, switching and terminal service charges in the shared asset area. These expenses are included in purchased services and other on the consolidated income statements. Future payments due to Conrail under the shared asset area agreements are shown in the table below.

| *(Dollars in Millions)* | **Conrail Shared** |

Also, included in equity earnings of affiliates are CSX's 42% share of Conrail's income and its amortization of the fair value write-up arising from the acquisition of Conrail and certain other adjustments. The amortization primarily represents the additional after-tax depreciation expense related to the write-up of Conrail's fixed assets when the original purchase price, from the 1997 acquisition of Conrail, was allocated based on fair value. This write-up of fixed assets resulted in a difference between CSX's investment in Conrail and its share of Conrail's underlying net equity, which is $315 million as of December 2025.

**NOTE 16. Other Comprehensive Income (Loss)**

&nbsp;&nbsp;&nbsp;&nbsp;

CSX reports comprehensive earnings or loss in accordance with the *Comprehensive Income Topic* in the ASC in the consolidated comprehensive income statement. Total comprehensive earnings are defined as all changes in shareholders' equity during a period, other than those resulting from investments by and distributions to shareholders (e.g. issuance of equity securities and dividends). Generally, for CSX, total comprehensive earnings equal net earnings plus or minus adjustments for pension and other post-retirement liabilities as well as derivative activity and other adjustments. Total comprehensive earnings represent the activity for a period net of tax and were $2.9 billion, $3.5 billion and $3.8 billion for 2025, 2024 and 2023, respectively.

While total comprehensive earnings is the activity in a period and is largely driven by net earnings in that period, AOCI represents the cumulative balance of other comprehensive income, net of tax, as of the balance sheet date. For CSX, AOCI is primarily the cumulative balance related to pension and other post-retirement benefit adjustments, interest rate derivatives and CSX's share of AOCI of equity method investees.

**NOTE 17. Segment Reporting and Significant Expenses**

The Company has two operating segments: rail and trucking. Although the Company provides a breakdown of revenue by line of business, the overall financial and operational performance of the railroad is analyzed as one operating segment due to the integrated nature of the rail network. The "Rail" column in the table below includes the activities of all CSX entities other than the trucking company, Quality Carriers, and also includes the Company's equity in the net income of equity method investments. As the trucking segment is not material for separate disclosure as a reportable segment, the results of these operations are included as a reconciliation to the Company's consolidated results in the tables below. See additional information in Note 1, *Nature of Operations and Significant Accounting Policies.*

The Company's chief operating decision maker ("CODM") is its Chief Executive Officer. The CODM reviews information presented on a consolidated basis, accompanied by supplemental information about the trucking segment separately, for purposes of allocating resources and evaluating financial performance. The Company has determined that operating income is the key measure of segment profit or loss as this measure is the focus of the CODM in developing financial plans, including resource allocation, and evaluating actual financial performance against plan. The CODM regularly reviews operating results broken out by significant expense.

*Additions*

During 2025 and 2024 the Company's trucking operating segment, which is solely comprised of Quality Carriers, completed several acquisitions that were immaterial individually and in aggregate. The acquisitions resulted in the addition of $5 million and $22 million of goodwill in the trucking operating segment in 2025 and 2024, respectively, which were subsequently impaired. Other intangible assets recognized as part of these acquisitions were $5 million and $25 million in 2025 and 2024, respectively.

*Amortization*

The Company's intangible assets balance primarily relates to intangibles recognized as part of the acquisition of Quality Carriers in 2021. Intangible assets recognized from the acquisition of $180 million consist of $150 million of customer relationships and $30 million of trade names that will be amortized over a weighted-average period of 20 years and 15 years, respectively.

*2024 Impairment*

The Company performed a quantitative assessment, which used a combination of the income and market approaches, as of October 1, 2024, to estimate the fair value of Quality Carriers. The income approach used a discounted cash flow model with significant assumptions for future revenue growth, EBITDA margin, capital expenditures and discount rate. The market approaches used valuation and transaction multiples for selected guideline public companies. Based on the quantitative assessment, CSX concluded the fair value of Quality Carriers did not exceed the carrying value. As a result, a $108 million impairment charge in the trucking operating segment was recorded in operating expense in the accompanying consolidated income statements. These inputs are classified as Level 3 measurements within the fair value hierarchy.

The impairment was driven by lower than previously expected financial performance projections, which were updated during the Company's annual financial plan process that takes place in the fourth quarter. Updates to longer-term projections reflect the effects of a trucking recession that has extended beyond previous expectations as well as higher discount rates.

*2025 Impairment*

During third quarter 2025, the Company determined that the extended trucking market recession, ongoing economic uncertainty and lower than previously expected financial performance triggered the need to perform an interim impairment assessment for goodwill associated with Quality Carriers. The Company performed a quantitative assessment, which used a combination of the income and market approaches, as of August 1, 2025, to estimate the fair value of Quality Carriers. The income approach used a discounted cash flow model with significant assumptions for future revenue growth, EBITDA margin, capital expenditures and discount rate. The market approach used revenue and EBITDA multiples for selected guideline public companies. These inputs are classified as Level 3 measurements within the fair value hierarchy. Based on the quantitative assessment, CSX concluded the fair value of Quality Carriers did not exceed its carrying value. As a result, all of the remaining Quality Carriers goodwill in the trucking operating segment was determined to be fully impaired and a $164 million impairment charge was recorded in operating expense in the accompanying consolidated income statements.

*Additional Information*

In addition to the quantitative assessment of goodwill, CSX evaluated the recoverability of the long-lived assets on the Quality Carriers reporting unit in the trucking operating segment in 2025 and 2024. Based on these assessments, CSX concluded the carrying values of these assets were recoverable and no impairment was recorded.

The Company performed a qualitative assessment over the goodwill of the reporting units in the rail segment during fourth quarter 2025 and 2024. No impairment was recorded as a result of those assessments.

***Evaluation of Disclosure Controls and Procedures***

As of December 31, 2025, under the supervision and with the participation of CSX's Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), management has evaluated the effectiveness of the design and operation of the Company's disclosure controls and procedures. Based on that evaluation, the CEO and CFO concluded that, as of December 31, 2025, the Company's disclosure controls and procedures were effective at the reasonable assurance level in timely alerting them to material information required to be included in CSX's periodic SEC reports.

***Management's Report on Internal Control over Financial Reporting***

CSX's management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of the management of CSX, including CSX's CEO and CFO, CSX conducted an evaluation of the effectiveness of the Company's internal control over financial reporting as of December 31, 2025, based on the 2013 framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, which is also referred to as COSO. Based on that evaluation, management of CSX concluded that the Company's internal control over financial reporting was effective as of December 31, 2025. Management's assessment of the effectiveness of internal control over financial reporting is expressed at the level of reasonable assurance because a control system, no matter how well designed and operated, can provide only reasonable, but not absolute, assurance that the control system's objectives will be met.

The Company's internal control over financial reporting as of December 31, 2025, has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included elsewhere herein.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Shareholders and the Board of Directors of CSX Corporation

**Opinion on Internal Control Over Financial Reporting**

We have audited CSX Corporation's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, CSX Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated income statements, comprehensive income statements, statements of changes in shareholders' equity and cash flow statements for each of the three years in the period ended December 31, 2025, and the related notes and our report dated February 12, 2026, expressed an unqualified opinion thereon.

**Basis for Opinion**

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

**Definition and Limitations of Internal Control over Financial Reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

CSX Corporation ("CSX" or the "Company") has granted to you performance units pursuant to the CSX 2019 Stock and Incentive Award Plan (the "Plan"), which is incorporated herein by reference, and together with this Notice and Performance Unit Award Agreement (the "Award Agreement") set forth the terms and conditions of this grant. The performance units are granted as part of the Company's 2025 – 2027 Long-Term Incentive Plan, wherein each performance unit represents one share of CSX common stock.

CSX reserves the right to terminate, change or amend this Award Agreement or the Plan at any time in accordance with the terms of the Plan. Receipt of this grant does not obligate CSX to make any additional grants to you. This grant, or a portion thereof, may be subject to forfeiture if you terminate employment as set forth in this Award Agreement.

**ACTION REQUIRED: YOU MUST ACCEPT YOUR AWARD AGREEMENT ELECTRONICALLY OR YOUR AWARD MAY BE SUBJECT TO FORFEITURE.**

Please review the terms of the Notice, Award Agreement and the Plan carefully; a copy of the Plan is available for review on the CSX Gateway.

------

**PURPOSE AND OBJECTIVE**

CSX Corporation ("CSX" or the "Company") issues Performance Grants, as described in the CSX 2019 Stock and Incentive Award Plan (referred to herein as Performance Units) in order to reward eligible employees for their contribution toward CSX's improved operating and financial performance, ultimately creating shareholder value and driving long-term success for CSX. Consistent with your September 26, 2025 Employment Letter (the "Letter Agreement"), the Performance Units constitute a portion of your Sign-On Equity Award (as defined in your Letter Agreement) and are issued as part of the Company's 2025 - 2027 Long-Term Incentive Plan and are subject to the terms and conditions of the CSX 2019 Stock and Incentive Award Plan (the "Plan"). A Performance Unit represents the right to receive one share of CSX common stock.

Performance Units become earned based upon certification of CSX's achievement of predetermined performance goals set forth on Exhibit A (the "Performance Measures") during the Performance Period (as set forth on Exhibit A). Grants of Performance Units are approved by the Compensation and Talent Management Committee (the "Committee") of the Board of Directors of CSX (the "Board") and the Board.

**VESTING AND PERFORMANCE PERIOD**

The Performance Period and the Performance Measures for purposes of the Performance Units are set forth on Exhibit A attached hereto. Any Performance Units that become earned under this Award Agreement and Exhibit A will vest in full on September 28, 2028 (the "Vesting Date"), subject to your continued employment through the Vesting Date, except as provided below under *Impact of Change in Employment Status*.

**EARNING AND VESTING OF PERFORMANCE UNITS** 

As shown in Exhibit A, the number of Performance Units earned will be equal to a percentage of your granted Performance Units based upon the achievement of the Performance Measures. All earned and vested Performance Units will be settled in CSX common stock within 60 days following the Vesting Date.

No Performance Units will be earned under the Plan unless and until the Committee approves the payout percentage based upon the level of achievement of the Performance Measures for the Performance Period. No Performance Units will vest (even if earned) if you do not remain in continued employment through the Vesting Date, except as provided below under *Impact of Change in Employment Status*.

**IMPACT OF CHANGE IN EMPLOYMENT STATUS**

Performance Units generally will be earned and vested subject to your continued employment with CSX or its affiliates through the Vesting Date. Except as provided below, if your employment terminates prior to the Vesting Date, you shall forfeit any and all Performance Units (whether or not earned). All earned and vested Performance Units will be settled as soon as practicable, but in no event later than 60 days, following the Vesting Date.

***Termination without Cause or for Good Reason Prior to Vesting***

Consistent with your Letter Agreement, in the event of your separation from employment due to a termination of employment by the Company without Cause or if you resign for Good Reason (each as defined in your Letter Agreement) prior to your being Retirement Eligible (as defined

------

below), subject to your execution and non-revocation of the Company's customary separation and release of claims agreement (the "Release Agreement"), the Performance Units will be eligible to vest on a pro-rata basis (determined by multiplying the number of shares of CSX common stock covered by the Performance Units by a fraction, the numerator of which is the number of months that have elapsed from your employment start date of September 28, 2025 through your termination date and the denominator of which is the total number of months in the vesting period), subject to the satisfaction of the Performance Measures (to the extent not previously satisfied prior to the termination date). Any CSX common stock that is earned and vested will be issued as soon as practicable, but in no event later than 60 days, after the Vesting Date.

***Termination Due to Death or Disability Prior to Vesting***

Consistent with your Letter Agreement, if your employment terminates due to death or Disability the Vesting Date, the Performance Units shall be eligible to become earned and vested (and would be paid) in the same manner as set forth above under *Termination without Cause or for Good Reason Prior to Vesting*. In the case of death, any such earned and vested Performance Units shall be paid to your estate, or as otherwise required by law "Disability" shall mean a disability rendering you physically or mentally unable to performance your duties.

***Termination Due to Retirement Prior to Vesting***

Consistent with your Letter Agreement, if your employment terminates after becoming Retirement Eligible either (i) by CSX without Cause or by you for Good Reason or (ii) by you due to your voluntary retirement by providing CSX with at least 180 days' notice of your plans to retire (which period may be waived in full or in part by CSX), subject to your execution and non-revocation of the Release Agreement, the Performance Units will remain outstanding and will continue to vest and eligible to become earned subject to the satisfaction of the Performance Measures. Any such earned Performance Units shall be paid to you as soon as practicable, but in no event later than 60 days, following the Vesting Date. "Retirement Eligible" shall mean your attainment of age 60 plus at least 3 years of continued service with the Company (unless the Company has notified you of its intent to terminate your employment for Cause or grounds to terminate your employment for Cause exist at such time).

***Competing Employment Following Termination***

Notwithstanding the foregoing, if, following a separation of your employment for any reason, you violate the terms of your Confidentiality, Non-Solicitation and Non-Competition Agreement dated September 27, 2025, then the Performance Units shall be forfeited and terminated without further obligation on the part of CSX or any affiliate.

***Termination for Cause/Moral Turpitude*** 

If your employment is terminated for Cause, all unvested Performance Units shall lapse and terminate immediately.

**DIVIDEND EQUIVALENTS**

After the Vesting Date, you will be eligible to receive Dividend Equivalents based upon the number of earned and vested Performance Units. The Dividend Equivalents will equal the aggregate amount of dividends declared and paid per share of CSX stock for each quarter between the grant date set forth in the Notice and the Vesting Date multiplied by the number of earned and vested Performance Units paid to you. The Dividend Equivalents will be paid upon settlement in the form of CSX stock subject to applicable withholding taxes.

------

**TAXATION OF PERFORMANCE AWARDS**

Performance Units will be settled in shares of CSX common stock. The value received by you is taxable income; therefore, CSX is required to withhold income taxes at the prescribed rates for both supplemental income and employment taxes in accordance with applicable tax laws. CSX will withhold the minimum number of whole shares equal in value to the statutory minimum required amount. If you participate in the CSX Executives' Deferred Compensation Plan, you may be able to defer receipt of Performance Units in accordance with the terms of that plan.

**CHANGE OF CONTROL**

In the event of a Change of Control (as defined in your Form of Change of Control Agreement with the Company, dated as of September 28, 2025 (the "CIC Agreement")), the Performance Units will be treated in accordance with Section 13 of the Plan (or any equivalent successor provision) and the terms of your CIC Agreement.

**SHAREHOLDER RIGHTS**

The Performance Units shall confer no other shareholder rights upon you except as provided herein unless and until such time as the award has been settled by the issuance of CSX common stock to you.

CSX Corporation ("CSX" or the "Company") has granted to you non-qualified stock options ("Options") pursuant to the CSX 2019 Stock and Incentive Award Plan (the "Plan"), which is incorporated herein by reference, and together with this Notice and stock option agreement (the "Option Agreement"), set forth the terms and conditions of this grant. The Options provide you with the right to purchase CSX common stock at a pre-established price during a future time period.

CSX reserves the right to terminate, change or amend this Option Agreement or the Plan at any time in accordance with the terms of the Plan. Receipt of this grant does not obligate CSX to make any additional grants to you. This Option grant, or a portion thereof, may be subject to forfeiture if you terminate employment as set forth in the Option Agreement.

**ACTION REQUIRED: You must accept your Award Agreement electronically OR YOUR AWARD MAY BE SUBJECT TO FORFEITURE.**

Please review the terms of the Notice, Option Agreement and the Plan carefully; a copy of the Plan is available for review on the CSX Gateway.

------

**Purpose and Objective**

CSX Corporation ("CSX" or the "Company") issues non-qualified stock options, as described in the CSX 2019 Stock and Incentive Award Plan (referred to herein as Options) in order to reward eligible employees for their contribution toward CSX's improved operating and financial performance, ultimately creating shareholder value and driving long-term success for CSX. Consistent with your September 26, 2025 Employment Letter (the "Letter Agreement"), the Options constitute a portion of your Sign-On Equity Award (as defined in your Letter Agreement) and are subject to the terms and conditions of the CSX 2019 Stock and Incentive Award Plan (the "Plan"). An Option represents the right to purchase one share of CSX common stock at a pre-established price during a future time period.

**Vesting** 

The Options may be exercised once vested. Except as provided below under *Impact of Change in Employment Status*, the Options will vest and become exercisable in full on September 28, 2028 (the "Vesting Date"), subject to your continued employment through the Vesting Date.

**Impact of Change in Employment Status**

In the event of a termination of your employment before the Vesting Date for any reason other than as set forth below, all unvested Options shall be forfeited and terminated.

***Termination without Cause or for Good Reason Prior to Vesting***

Consistent with your Letter Agreement, in the event of your separation from employment due to a termination of employment by the Company without Cause or if you resign for Good Reason (each as defined in your Letter Agreement) prior to your being Retirement Eligible (as defined below), subject to your execution and non-revocation of the Company's customary separation and release of claims agreement (the "Release Agreement"), the Options will vest on a pro-rata basis determined by multiplying the number of shares of CSX common stock covered by the Options by a fraction, the numerator of which is the number of months that have elapsed from your employment start date of September 28, 2025 through your termination date and the denominator of which is the total number of months in the vesting period of the Options set forth under *Vesting* above.

***Termination Due to Death or Disability Prior to Vesting***

Consistent with your Letter Agreement, in the event of your separation from employment due to death or Disability prior to the Vesting Date, the Options will become vested on a pro-rata basis in the same manner as set forth above under *Termination without Cause or for Good Reason Prior to Vesting*. "Disability" shall mean a disability rendering you physically or mentally unable to performance your duties.

***Termination Due to Retirement Prior to Vesting***

Consistent with your Letter Agreement, if you separate from employment after becoming Retirement Eligible either (i) by CSX without Cause or by you for Good Reason or (ii) by you due to your voluntary retirement by providing CSX with at least 180 days' notice of your plans to retire (which period may be waived in full or in part by CSX), subject to your execution and non-revocation of the Release Agreement, the Options will remain outstanding and will continue to vest per the vesting schedule set forth under Vesting above. "Retirement Eligible" shall mean your attainment of age 60 plus at least 3 years of continued service with the Company (unless the Company has notified you of its intent to terminate your employment for Cause or grounds to terminate your employment for Cause exist at such time).

***Competing Employment Following Termination***

Notwithstanding the foregoing, if, following a separation of your employment for any reason, you violate the terms of your Confidentiality, Non-Solicitation and Non-Competition Agreement dated September 27, 2025, then any outstanding Options shall be forfeited and terminated without further obligation on the part of CSX or any affiliate.

------

***Termination of Employment Following Vesting*** 

In the event of your separation from employment after becoming Retirement Eligible or due to Disability, or death, you or your designated Beneficiary or estate will have until the Expiration Date (as defined in the Notice) to exercise any vested Options. Except as otherwise provided in the Plan, if you separate from employment with CSX for any other reason, you will have **<u>60 days</u>** after separation from employment to exercise any Options that are vested at separation from employment.

***Termination for Cause/Moral Turpitude*** 

If your employment is terminated for Cause, all rights under the unvested Options shall lapse and terminate immediately.

**Exercise**

You may exercise your vested Options, in whole or in part, to purchase a whole number of shares of CSX common stock at any time by following the exercise procedures below. All exercises must take place before the Expiration Date, or such earlier dates as established by the Notice, Option Agreement or the Plan, or such Options shall otherwise lapse.

Options may be exercised by: (a) paying cash, (b) executing a "cashless" exercise, or (c) executing a "cashless" exercise and "hold" transaction.

**Taxation of Stock Options**

An exercise of Options may generate federal and applicable state income and employment tax withholding obligations. The full purchase price of the shares being purchased through exercise of Options and the related withholding taxes for federal, state or local jurisdictions must be paid to CSX at the time of an exercise of Options. You acknowledge that CSX shall have the right to deduct any taxes required to be withheld by law in connection with the exercise of the Option from any amounts payable by it to you (including, without limitation, future cash wages).

**Non-Transferability**

The Options may not be sold, assigned, pledged, exchanged, or otherwise transferred, encumbered or disposed of by you other than by will or by the laws of descent and distribution, and are exercisable during your life only by you.

**Change of Control**

In the event of a Change of Control (as defined in your Form of Change of Control Agreement with the Company, dated as of September 28, 2025 (the "CIC Agreement")), the Options will be treated in accordance with Section 13 of the Plan (or any equivalent successor provision) and the terms of your CIC Agreement.

**Shareholder Rights**

The Options shall confer no other shareholder rights upon you unless and until such time as the Option has been exercised and shares of CSX common stock are issued to you.

**Not a Contract of Employment or Right to Future Awards**

Nothing in this Option Agreement shall be interpreted or construed to create a contract of employment between CSX and you or a right to receive equity awards in the future. This Option Agreement is intended solely to provide you an incentive to continue existing employment.

------

**Severability**

If any terms and conditions herein are, become, or are deemed to be invalid, illegal, or unenforceable in any jurisdiction, such provision shall be construed or deemed amended or limited in scope to conform to applicable laws or, in the discretion of CSX, it shall be stricken and the remainder of the terms and conditions shall remain in force and effect.

**Choice of Law; Jurisdiction**

All questions pertaining to the construction, regulation, validity, and effect of the terms and conditions shall be determined in accordance with the laws of the state of Florida, without regard to the conflict of laws doctrine.

**Restrictions on Resales of Shares Acquired Pursuant to Option Exercise**

CSX may impose such restrictions, conditions or limitations as it deems appropriate as to the timing and manner of any resales by you or other subsequent transfers by you of any common stock issued as a result of the exercise of the Option, including without limitation (a) restrictions under an insider trading policy; (b) restrictions designed to delay and/or coordinate the timing and manner of sales by you and other option-holders; and (c) restrictions as to the use of a specified brokerage firm for such resales or other transfers.

**Nonqualified Stock Option; Section 409A**

The Option is intended to be a non-qualified stock option and is not intended to be an incentive stock option under Section 422 of the Internal Revenue Code of 1986, as amended and will be interpreted accordingly.

The Options are intended to comply with Section 409A of the Code ("Section 409A") to the extent subject thereto, and shall be interpreted in accordance with Section 409A and treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the grant date set forth in the Notice.

**Clawback Provision**

In consideration of the grant of the Award under this Award Agreement, you agree that, to the extent that you are or become covered by the CSX Corporation Financial Restatement Compensation Recoupment Policy or any other clawback policy adopted by CSX (as applicable, a "Clawback Policy"), the Award granted to you pursuant to this Award Agreement and any shares of CSX common stock issued upon settlement thereof shall be subject to such Clawback Policy as may be in effect from time to time. In addition, by accepting this Award and in consideration for the opportunity to receive the compensation as provided under this Award, you agree that (i) any other compensation granted, awarded, paid or otherwise provided to or earned by you, whether before, on or following the date hereof, that is covered by an applicable Clawback Policy shall be subject to the recoupment and/or forfeiture provisions thereof, and (ii) such Clawback Policy shall be deemed to amend (on both a retroactive and prospective basis) the terms of any employment, compensation or similar agreement to which you are a party, and the terms of any compensation plan, program or agreement, under which any incentive-based compensation has been or may be granted, awarded, paid or otherwise provided to or earned by you (including without limitation, an award agreement evidencing an award granted to you under the Plan). In the event it is determined that any amounts granted, awarded, paid or otherwise provided to or earned by you must be forfeited or reimbursed to the Company pursuant to any such Clawback Policy, you agree that you will promptly take any action necessary to effectuate such forfeiture and/or reimbursement.

**By accepting this award of Options, you acknowledge and agree that this Option Agreement is governed by the terms and conditions of the Plan and is subject to all policies of CSX, including any applicable policy on the remuneration of incentive compensation. Unless defined in this Option Agreement, capitalized terms shall have the meanings ascribed to them in the Plan. This Option Agreement shall be effective as of October 1, 2025.**<br>

&nbsp;&nbsp;&nbsp;&nbsp;

**EMPLOYMENT SEPARATION AGREEMENT AND RELEASE**

In consideration of the agreement of CSX Corporation, and its subsidiaries and affiliates, including CSX Transportation, Inc. (collectively the "<u>Company</u>" or "<u>CSX</u>"), to pay me the monetary amounts and other benefits described in Paragraph 5 below in accordance with the provisions of the CSX Corporation Executive Severance Plan, as amended and restated (the "<u>Plan</u>"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.<u>Termination of Employment</u>. Subject to my right to revoke this Employment Separation Agreement and Release (this "<u>Agreement</u>") as provided in this Agreement, I understand that my employment relationship with the Company has been terminated. My employment will cease and terminate in all capacities on October 29, 2025 (the "<u>Termination Da</u>te"). Effective as of the Termination Date, I hereby relinquish forever any seniority rights I may have under any labor agreement with the Company or its subsidiaries and affiliates, including Consolidated Rail Corporation, and I agree that upon the Termination Date, my compensation and other employment terms, conditions and benefits will be as set forth in Paragraph 5 below. I also hereby resign effective immediately from all elected, appointed or other positions held within the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.<u>Release of Claims.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)In consideration of the Company's obligations under this Agreement and for other valuable consideration, subject to the limitations set out in subpart (b) of this Paragraph 2, I unconditionally and irrevocably release the Company, and all of its past and present officers, directors, employees, agents, representatives, assigns, attorneys, insurers, predecessors, benefit plans, the benefit plans' sponsors, fiduciaries, administrators, affiliates and agents, and any other persons acting by, through, under or in concert with any of the persons or entities listed in this Paragraph (hereinafter the "<u>Released Parties</u>") from any and all known or unknown claims, charges, promises, actions, or similar rights that I presently may have ("<u>Claims</u>"), including but not limited to, those relating in any way to my employment, or to my separation from employment with the Company as described in Paragraph 1 above, except for the payment(s) or benefits described in Paragraph 5 below. This includes a release of any rights or claims, if any, that I may have under Title VII of the Civil Rights Act of 1964, as amended by the Civil Rights Act of 1991, which prohibits discrimination in employment based on race, color, national origin, religion or sex; the Civil Rights Act of 1866, as amended by the Civil Rights Act of 1991, which requires equality in contractual relations without regard to race or national origin; the Equal Pay Act, which prohibits paying men and women unequal pay for equal work; the Americans with Disabilities Act of 1990, as amended, which prohibits discrimination against qualified individuals with disabilities; the Rehabilitation Act of 1973, which prohibits discrimination against the handicapped; the Employee Retirement Income Security Act; the Fair Labor Standards Act; Uniformed Services Employment and Reemployment Rights Act of 1994 (USERRA); the Family and Medical Leave Act; Executive Order 11246; the Genetic Information Nondiscrimination Act; the Federal Employers' Liability Act; the Sarbanes-Oxley Act; the Dodd-Frank Wall Street Reform and Consumer Protection Act; or any other federal, state or local laws or regulations prohibiting employment discrimination. This also includes a release of any rights or claims I may have under the Worker Adjustment and Retraining

------

Notification Act, its equivalent under state law, or any similar law that requires, among other things, that advance notice be given of certain workforce reductions. This also includes a release of any rights or claims I may have for wrongful discharge; breach of contract, whether express or implied; termination of employment in violation of any public policy; any other tort or contract claim; any claim for labor protection, whether under conditions imposed by the Surface Transportation Board, its predecessor, or any labor agreement; any claim under any workers' compensation law or any other claim for personal injury; and any other claim for relief of any nature.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)This Agreement does not prohibit the following rights or claims: (1) claims that first arise after I sign the Agreement or which arise out of or in connection with the interpretation or enforcement of the Agreement itself; (2) my right to file a charge or complaint with the EEOC, U.S. Department of Labor or similar federal or state agency, or my ability to participate in any investigation or proceeding conducted by such agency; and (3) any rights or claims, whether specified above or not, that cannot be waived as a matter of law pursuant to federal, state or local statute. If it is determined that any claim covered by this Agreement cannot be waived as a matter of law, I expressly agree that the Agreement will nevertheless remain valid and fully enforceable as to the remaining released claims. Nothing in this Agreement or otherwise is intended to (i) prevent or restrict me from making truthful statements in connection with any official investigation conducted by a court or a government, administrative or law enforcement agency or in any sworn testimony, in response to a subpoena or as otherwise required by law or (ii) restrict, prohibit or interfere with my right to initiate communications directly with, respond to an inquiry from, provide testimony before, cooperate or file a complaint with, or otherwise participate as a complainant or witness before, any self-regulatory organization or any federal, state or local governmental or regulatory authority (including any activities protected under the whistleblower provisions of any applicable laws or regulations), during which communications can be made without authorization by or notification to the Company. The Company may not retaliate against me for any of these activities, and nothing in this Agreement or otherwise requires me to waive any monetary award or other payment that I might become entitled to from the United States Securities and Exchange Commission ("<u>SEC</u>") or any other federal, state or local governmental agency or commission or self-regulatory organization. Further, nothing in this Agreement or otherwise precludes me from filing a charge of discrimination with the EEOC or a like charge or complaint with a state or local fair employment practice agency. For the avoidance of doubt, nothing herein prevents me from receiving any whistleblower award. Pursuant to the Defend Trade Secrets Act of 2016, the parties hereto acknowledge and agree that I will not have criminal or civil liability under any Federal or State trade secret law for the disclosure of a trade secret that (A) is made (i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. In addition and without limiting the preceding sentence, if I file a lawsuit for retaliation by the Company for reporting a suspected violation of law, I may disclose the trade secret to my attorney and may use the trade secret information in the court proceeding, if I (X) file any document containing the trade secret under seal and (Y) do not disclose the trade secret, except pursuant to court order.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)By signing this Agreement, I understand that as part of the Agreement above, I voluntarily and knowingly waive any and all of my rights or claims under the federal Age Discrimination in Employment Act of 1967 (ADEA), as amended, that may have existed prior to

------

the date I sign the Agreement. However, I am not waiving any future rights or claims under the ADEA or Title VII of the Civil Rights Act for actions arising after the date I sign this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)I understand that I am releasing Claims that I may not know about, and that is my knowing and voluntary intent. I expressly waive all rights I might have under any law that is intended to prevent unknown claims from being released. I understand the significance of doing so.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.(a)&nbsp;&nbsp;&nbsp;&nbsp;<u>Pursuit of Released Claims.</u> I agree to withdraw, and represent that I have withdrawn, all lawsuits, if any, against any Released Party, and I further represent that I will not file any lawsuit against any Released Party based on the claims released under this Agreement. I promise not to seek any damages, remedies or other relief for myself personally with respect to any claim purportedly released by this Agreement. However, I understand that nothing contained in this Paragraph 3 precludes me from challenging the validity of this Agreement under the ADEA, and this Paragraph 3 shall not apply to ADEA claims to the extent, if any, prohibited by applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;<u>Consequences of Violating Promises.</u> I agree to pay the reasonable attorneys' fees, costs, and expenses and any damages the Released Parties may incur as a result of my filing a lawsuit against any Released Party based on the claims released under this Agreement

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.I understand that the Company, in its sole discretion, retains the right at any time for any reason to amend, terminate or charge for welfare benefit plans, including without limitation medical benefits, and that any such benefits to which I am now entitled or to which I may become entitled in the future are subject to such right.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.(a)&nbsp;&nbsp;&nbsp;&nbsp;<u>Severance Payment.</u> I understand that I will, if I sign, and do not revoke, this Agreement in accordance with Paragraphs 15 and 16, receive severance pay that is above and beyond any remuneration for the performance of services, benefit plan payments or any other amounts to which I am otherwise entitled and which is in lieu of any payments under any other severance pay plan of the Company. Severance pay will be in an amount calculated pursuant to the Plan equal to the sum of (i) one (1) times my current base salary and (ii) one (1) times my current target bonus under the CSX Management Incentive Compensation Plan in effect for 2025 (the "<u>2025 MICP</u>"), in each case as set forth on the "Individual Statement of Executive Severance Payments" attached and incorporated as "Exhibit 1" to this Agreement. I have reviewed Exhibit 1 carefully, and I attest that it accurately states my current salary and current target bonus under the 2025 MICP. I understand that I will receive this severance pay in the form of monthly installment payments for a period of 12 months on or about the first of each month beginning the first day of the month following the date this Agreement becomes effective under Paragraph 16.

I understand that the Company will withhold appropriate amounts for federal, state and local income and employment taxes and all other legally required withholdings. I further understand that throughout the period of time during which I receive severance pay in monthly payments, I will remain eligible to continue to participate in medical and dental benefits to the extent provided under such plan. Except as otherwise expressly provided in the Plan, I

------

understand that I will not be eligible: 1) to receive any further contributions under the CSX Corporation 401(k) Plan, ("<u>CSXtra</u>"); 2) to accrue any additional benefits under the CSX Pension Plan; 3) to receive dependent care reimbursement benefits; 4) to participate in the Company's disability plan; 5) to participate in the Travel Accident Plan; 6) to accrue sick leave or vacation days; 7) to continue life insurance benefits, subject to the conversion and portability language of the relevant plan document; or 8) to receive any form of incentive compensation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;<u>Outplacement.</u> I understand that I shall be eligible for outplacement services for one (1) year following my Termination Date through an organization designated by the Company, provided that I initiate these outplacement services within six (6) months after my Termination Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;<u>Bonus.</u> I understand that I will be eligible for a prorated bonus under the 2025 MICP, based on the number of days in 2025 through my Termination Date and the amount of the bonus that is earned and paid based on the actual achievement of the performance criteria applicable to the 2025 MICP following the end of the 2025 performance year, paid in a lump sum at the time bonuses are normally paid under the 2025 MICP, but in no event later than March 15, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;<u>Long Term Incentives.</u> For the 2023 – 2025, 2024 – 2026 and 2025 – 2027 Long-Term Incentive Plans, I understand I will retain a prorated portion of Performance Units, Restricted Stock Units and Stock Options in accordance with the terms set forth in the applicable award agreements governing these awards, which provide for such proration based on the number of full months since the preceding vesting date (or if there has not yet been a vesting date, since the grant date) and through and including the month in which the Termination Date occurs, with such prorated portion being settled or becoming exercisable (as applicable) on the original schedule as set forth in the award agreement that would have applied had I remained employed through the next applicable vesting date (and in the case of Performance Units, subject to the satisfaction of the applicable performance conditions at the end of the performance period). Further, notwithstanding anything to the contrary in the applicable award agreements, any of my Stock Options that are vested as of my Termination Date (including those that vest on a pro-rated basis pursuant to this Section 5(d)) will remain exercisable through the original expiration date of such Stock Options as set forth in the applicable award agreement (which, for the avoidance of doubt, is no later than ten (10) years from the applicable grant date). Any equity- or equity-based awards that I hold with respect to shares of CSX common stock that do not vest in accordance with this Paragraph 5(d), as set forth on "Exhibit 1" attached to this Agreement, will be forfeited and cancelled as of the Termination Date for no consideration. I have reviewed Exhibit 1 carefully, and I attest that it accurately states all of my prorated awards that will vest. For purposes of measuring the pro-ration, the last day of my employment will be deemed to have been the Termination Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp;<u>Financial Planning Assistance.</u> I understand that I will receive financial and tax planning assistance for one (1) year following my Termination Date through organizations designated by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp;<u>Health Continuation</u>. I understand that I will remain eligible to continue participation in the Company's medical and dental plans on the same basis as I participated as of immediately prior to the Termination Date, for a period ending on the earlier of (i) twelve (12)

------

months following the Termination Date and (ii) the date on which I become eligible for health coverage from a subsequent employer. Access to other applicable benefits in which I participated as of immediately prior to the Termination Date will be offered in accordance with the requirements of the Consolidated Omnibus Budget Reconciliation Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.&nbsp;&nbsp;&nbsp;&nbsp;<u>Cooperation.</u> I shall cooperate with and assist the Company with any dispute, proceeding, arbitration, investigation or litigation involving the Company in which I have knowledge or involvement as a result of my employment with the Company. I acknowledge that the demands of such proceedings are not necessarily within the control of the Company and agree that notwithstanding any other provision of this Agreement, I will make myself available to the extent possible and will advise the Company immediately in writing of any contacts from third-parties to me in connection with such proceedings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.&nbsp;&nbsp;&nbsp;&nbsp;<u>Non-Disparagement.</u> Subject to the employee protections set forth in Section 2(b), I agree to refrain from expressing (or causing others to express) to any third party any derogatory or negative opinions concerning the Company or their respective officers, directors, operations, services or employees. Notwithstanding the above, I understand that nothing herein shall be construed to prevent or restrict me from responding truthfully to questions or requests as part of an inquiry conducted by a court, government or law enforcement agency or in response to a subpoena or as otherwise required by law, or as otherwise expressly provided for in this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.&nbsp;&nbsp;&nbsp;&nbsp;<u>Administrative Action.</u> For the avoidance of doubt, I understand that nothing in this Agreement, including Paragraph 2(b), Paragraph 6 (Cooperation), Paragraph 7 (Non-Disparagement) or Paragraph 10 (Confidential Information), shall prevent me from making truthful statements in connection with any sworn testimony or agency investigation or shall restrict me from initiating communications directly with, responding to an inquiry from, or providing testimony before any self-regulatory organization or any federal or state regulatory authority, including the SEC. Nor shall anything in this Agreement interfere with my right to receive a monetary award from the SEC pursuant to the SEC's whistleblower bounty program, or directly from any other federal or state agency pursuant to a similar whistleblower program.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.&nbsp;&nbsp;&nbsp;&nbsp;<u>Waiver of the Right to Re-employment.</u> I agree that I waive any right to reemployment with the Company. I understand and agree that if I reapply for employment with the Company, my application may be subject to rejection and that this Agreement is valid legal grounds for rejecting my application. Notwithstanding the above, I acknowledge and agree that in the event that I apply for, am offered a position and accept and the Company does not exercise its right to reject my application under this Paragraph 9, or if I am reinstated with the Company, I may be obligated to repay to the Company a portion of the severance pay that I receive in accordance with this Agreement and under the Plan, and I accept that obligation as a condition of this Agreement. In any case, if I accept a position or if I am reinstated during the period that I am receiving severance pay under this Agreement, I understand and agree that I will not be eligible to receive continued severance pay, effective upon the date of my acceptance of a position or upon my reinstatement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.&nbsp;&nbsp;&nbsp;&nbsp;<u>Confidential Information.</u> I understand that during my employment, I have learned trade secrets and other information confidential to the Company and that the Company would be substantially injured if the confidentiality of such information were not maintained. For

------

the purposes of this Paragraph, "Confidential Information" means and includes every item of and all the contents of any discussions, documents, information, technology, procedures, customer lists, business plans, employee compensation data, pricing information, strategies, software, financial data, ideas and assumptions and all other material relating to or in connection with my employment with the Company and their property, business methods and practices, suppliers and customers, other than that which is generally known to the public. To the extent that the Confidential Information comprises any written material or other material in a reproducible form by any means whatsoever, whether manual, mechanical or electronic, I will not copy, extract or reproduce the same by any means whatsoever, nor provide nor otherwise make such material available to any third party, nor use such Confidential Information for my own purposes.

I acknowledge that during the course of my employment I may have become aware of communications or documents protected by the attorney client privilege or the work product doctrine, and that I am not entitled to waive such privilege or to disclose such information or communications to others, except as required by law and subject to conditions set forth herein.

Subject to the employee protections set forth in subpart (b) of Paragraph 2, I agree (i) not to disclose to third persons such protected documents or Confidential Information without the prior consent of the Company, whether for compensation or otherwise, (ii) not to use such documents or Confidential Information for any purpose detrimental to the Company and (iii) to use my best possible reasonable efforts to ensure that any person to whom the Confidential Information is disclosed pursuant to this Agreement keeps the same secret and confidential and observes an obligation of confidentiality in relation to the matters specified in this Paragraph.

Notwithstanding the above, nothing in this Agreement shall prevent or restrict me from responding truthfully to inquiries as part of an official investigation conducted by a court or a government, administrative or law enforcement agency or in response to a subpoena or as provided for in Paragraph 2(b) above or as otherwise required by law. Additionally, I understand that nothing in this Agreement is intended to prohibit or interfere with my right to participate as a complainant or witness in a governmental agency investigation (including any activities protected under the whistleblower provisions or any applicable law or regulations), during which communications can be made without authorization by or notification to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.&nbsp;&nbsp;&nbsp;&nbsp;<u>Return of Property.</u> I have returned, or I agree to return all property belonging to the Company, including without limitation all keys, credit cards, manuals, computers, equipment and software, records, data, plans, customer lists, computer programs and related documentation or other documents or materials of any nature that are in my possession or control that I obtained from the Company or compiled or produced for the Company during my employment and any and all copies thereof, which shall include all confidential and/or proprietary information as described in Paragraph 10 of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.&nbsp;&nbsp;&nbsp;&nbsp;<u>No Admission of Liability.</u> It is understood and agreed that this Agreement and the furnishing of the consideration for this Agreement shall not be deemed or construed at any time for any purpose as an admission of liability or violation of any applicable law by the Released Parties. Liability for any and all claims is expressly denied by the Released Parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13.&nbsp;&nbsp;&nbsp;&nbsp;<u>Binding Agreement.</u> I agree that all of the provisions of this Agreement are binding upon my heirs, executors, administrators and assigns. I understand that by signing this

------

Agreement I am not giving up any rights I currently have under the CSX Pension Plan or CSXtra.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14.&nbsp;&nbsp;&nbsp;&nbsp;<u>Severability.</u> If any provision of this Agreement or the application thereof is held invalid, the invalidity shall not affect other provisions or applications of the Agreement which can be given effect without the invalid provisions or application; and to this end the provisions of this Agreement are declared to be severable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15.&nbsp;&nbsp;&nbsp;&nbsp;<u>Review Period.</u> The Company advised me to take this Agreement home, read it, and carefully consider all of its terms before signing it. I acknowledge that I was given a period of twenty-one (21) days to review and consider this Agreement, and that I was encouraged to consult an attorney before signing it. I understand that I may use as much or all of this 21-day period as I wish prior to signing and have done so. I further acknowledge that at the beginning of this 21-day period, I received a copy of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16.&nbsp;&nbsp;&nbsp;&nbsp;<u>Right of Revocation.</u> I understand that I may revoke this Agreement within seven (7) days (the "<u>Revocation Period</u>") after I sign it by written notice to:

CSX

Attn: Michelle Mullen

Total Rewards – J400

To constitute an effective revocation, the Company must in fact receive the written revocation by the close of business on the last day of the Revocation Period. Upon the expiration of the Revocation Period without receipt of such a statement, this Agreement will become effective and irrevocable. I understand that if I do not sign or if I revoke this Agreement, I will not receive the payments or benefits described in Paragraph 5 of this Agreement. If I do not revoke this Agreement, it will go into effect on the day after the last day of the Revocation Period, which will be the "Effective Date" of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17.&nbsp;&nbsp;&nbsp;&nbsp;<u>Entire Agreement.</u> I represent that in signing this Agreement, I do not rely on nor have relied on any representation or statement not specifically set forth in this Agreement by any of the Released Parties with regard to the subject matter, basis or effect of this Agreement or otherwise. This Agreement may not be changed orally, and any written change or amendment must be signed and accepted by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18.&nbsp;&nbsp;&nbsp;&nbsp;<u>Governing Law.</u> This Agreement will be governed, construed, and interpreted under the laws of the State of Florida and, where applicable, Federal law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19.&nbsp;&nbsp;&nbsp;&nbsp;<u>Section 409A.</u> To the extent any payments or benefits under this Agreement are subject to Section 409A of the Internal Revenue Code of 1986, as amended (the "<u>Code</u>"), this Agreement will be interpreted and administered to the maximum extent possible to comply with Section 409A of the Code. For purposes of any payments or benefits under this Agreement subject to Section 409A of the Code:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;I will not be considered to have terminated employment with the Company and its affiliates unless I would be considered to have incurred a "separation from service" within the meaning of Section 409A of the Code. Each separate payment to be made or benefit to be provided under this Agreement will be construed as a separate identified payment for purposes of Section 409A of the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;If I am a "specified employee" within the meaning of Section 409A of the Code at the time of my separation from service, to the extent required under Section 409A of the Code to avoid accelerated taxation and tax penalties, any amounts payable during the six (6) month period immediately following my separation from service will instead be paid on the first business day after the date that is six (6) months following my separation from service (or, if earlier, my date of death).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;Notwithstanding anything to the contrary in the Plan or this Agreement, (x) no payments under the Plan will be made until the Effective Date, (y) if the period during which I may execute this Agreement begins in one calendar year and ends in the next calendar year, then the payments will not commence until the second calendar year and (z) any such payments that are delayed pursuant to the foregoing clauses (x) or (y) will instead be made in the first payroll period to occur after the date this Agreement becomes effective and the start of the second calendar year (if applicable).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;The Company makes no representation that payments described in this Agreement will be exempt from or comply with Section 409A.

I HAVE CAREFULLY READ THIS AGREEMENT. I FULLY UNDERSTAND THE FINAL AND BINDING EFFECT OF THIS AGREEMENT AND ACKNOWLEDGE THAT IT CONTAINS AN UNCONDITIONAL, GENERAL, AND VOLUNTARY RELEASE OF ALL KNOWN AND UNKNOWN CLAIMS THAT I MIGHT HAVE RELATING TO, OR ARISING OUT OF, MY EMPLOYMENT WITH THE COMPANY. I ENTER INTO THIS AGREEMENT VOLUNTARILY, WITHOUT COERCION, AND BASED ON MY OWN JUDGMENT AND NOT IN RELIANCE UPON ANY REPRESENTATIONS, SUGGESTIONS OR PROMISES BY THE COMPANY, OTHER THAN THOSE CONTAINED HEREIN OR IN THE PLAN. I AM SIGNING THIS AGREEMENT VOLUNTARILY AND WITH THE FULL INTENT OF RELEASING THE COMPANY FROM ALL CLAIMS RELATING TO, OR ARISING OUT OF, MY EMPLOYMENT AND THE TERMINATION OF MY EMPLOYMENT.

Exhibit 19

**<u>CSX CORPORATION</u>**

**INSIDER TRADING POLICY**

**CSX Policy Owner:** Office of the Corporate Secretary

**Effective Date:** Revised December 2025

**Objective**

This CSX Insider Trading Policy (the "**Policy**" or "**Insider Trading Policy**") is intended to reinforce compliance with applicable federal securities laws by CSX Corporation and its subsidiaries (collectively, "**CSX**" or the "**Company**") and all directors, officers and employees thereof. In addition, the Policy discusses the potential legal consequences and disciplinary actions for trading on the basis of material nonpublic information or sharing such information with others who may do so.

**Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• This Policy outlines conduct prohibited under federal securities laws, as well as potential legal penalties and disciplinary action that may result from a violation of this Policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• This Policy provides guidance related to the handling of material nonpublic information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• This Policy provides guidance on transactions involving CSX securities, including trading windows and blackout periods, as well as the procedures for Covered Persons to obtain pre-clearance for such transactions.

**Common Terms Used Throughout This Policy**

**"Blackout Periods"** are the periods during which Covered Persons are prohibited from trading in CSX securities (except for transactions governed by a 10b5-1 Plan).

**"Covered Persons"** are individuals subject to the additional requirements and restrictions set forth in Article III of the Policy and include members of the Board of Directors, executive officers and certain other employees of the Company, as identified by senior management, who regularly may have access to material nonpublic information about the Company.

*CSX Insider Trading Policy (Revised November 2024)*

------

**"Material Information"** - In general, information is "material" if a reasonable investor would consider it important in making a decision to buy, sell or hold securities or on how to vote those securities. Material information can be positive or negative. You should consider any information that could be expected to affect the Company's stock price to be material. Examples of material information include, but are not limited to, information relating to:

the financial condition and operating results of a company, including earnings information,

significant regulatory developments,

the possibility of mergers, acquisitions or takeovers,

the possible initiation of a proxy fight,

the purchase or sale of major assets,

securities offerings,

important business developments, such as significant changes in operations or business plans, stock splits or changes in dividend or stock repurchase policies,

a change in auditors or notification that the auditor's reports may no longer be relied upon,

significant changes in the board or senior management,

significant disputes, claims, investigations or litigation or litigation developments or the resolution thereof,

significant labor disputes or negotiations or the resolution thereof, and

significant cybersecurity or data protection incidents.

Keep in mind that enforcement authorities judging securities transactions will do so after the fact, and will use hindsight in judging what is "material". When in doubt, information should be presumed to be material.

**"Nonpublic Information"** - Information is "nonpublic" if it has not been disclosed to the public generally. For information to be considered public, it must have been widely disseminated and the investing public must have had time to absorb the information. You should consider information nonpublic until the second business day after the information is publicly released through a press release or a widely circulated public disclosure document filed with the SEC, such as a prospectus, Form 10-K, Form 10-Q or Form 8-K report. For example, if information is disclosed via press release before the market opens on a Monday, it can be considered public beginning that Wednesday.

**"Pre-Clearance"** is the process that all Covered Persons must follow prior to engaging in a transaction in CSX securities.

**"Tipping"** is the sharing of information with others who might trade or recommend sales or purchases to others based on that information.

**"Transactions"** include the purchase and sale of: (i) CSX securities, (ii) derivatives of CSX securities, excluding awards of employee stock options, and (iii) securities within the Company's employee benefit plans, including but not limited to the Company's 401(k) plans or Employee Stock Purchase Plan, as applicable.

------

**Important Sources of Information**

If you need additional information, please call the Office of the Corporate Secretary at (904) 359-3256.

**Information provided in this Policy is for internal CSX use only and should not be communicated to, or duplicated for, any outside party without written permission from the Law Department.**

**<u>I. BACKGROUND</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.Purpose**

CSX is an issuer of securities that are registered with the Securities and Exchange Commission (the "**SEC**"). Such registration allows the securities to be publicly traded, but also imposes obligations upon the Company and its directors, officers and employees. The purpose of this Insider Trading Policy is to reinforce compliance with applicable federal securities laws by CSX and its directors, officers and employees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.General**

The purchase or sale of CSX securities while aware of material nonpublic information, or the disclosure of such information to others who may trade or recommend sales or purchases to others on the basis of that information ("**tipping**"), is prohibited by federal securities laws. In addition, CSX, members of management or directors could be penalized as controlling persons of those who trade on material nonpublic information even if not involved in the prohibited activities themselves.

In addition, CSX itself must comply with federal securities laws applicable to its own securities trading activities, and will not effect transactions in respect of its securities, or adopt any securities repurchase plans, when it is in possession of material nonpublic information, other than in compliance with applicable law, subject to the policies and procedures attached as Exhibit A hereto and with the prior approval of the Senior Vice President - Chief Legal Officer and Corporate Secretary or the Assistant Corporate Secretary, or their designees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.Legal Penalties**

The penalties for trading on material nonpublic information are severe, and can include disgorgement of the unlawful profits, civil penalties of up to three times the profit gained or loss avoided, criminal fines of up to $5,000,000 and/or a jail term of up to 20 years.

In addition, a person who tips material nonpublic information to others may also be liable for transactions by the tippees to whom he or she has disclosed such information. Tippers can be subject to the same penalties and sanctions as the tippees, and the SEC has imposed large penalties even when the tipper did not profit from the transaction. A tipper also can be criminally liable even when they did not stand to gain monetarily from disclosing the information (which can include disclosing to a friend or relative) if they received some personal benefits from sharing the information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.CSX Disciplinary Action**

The legal penalties described above are in addition to disciplinary action by CSX, up to and including termination of employment, for violation of this Policy.

------

**<u>II. STATEMENT OF POLICY APPLICABLE TO ALL CSX DIRECTORS, OFFICERS AND EMPLOYEES</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.Restrictions on CSX Trades and Use of Company Information**

No CSX director, officer or employee (including a director, officer or employee of any CSX subsidiary) (an "**Insider**") may purchase, sell or otherwise conduct transactions in any CSX security while he or she is aware of material nonpublic information about CSX. Former employees of CSX remain subject to the provisions of the Insider Trading Policy until they no longer possess material nonpublic information about the Company. In addition, CSX directors, officers and employees may not disclose information to others who might trade or recommend sales or purchases to others based on that information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.Safeguarding Material Nonpublic Information**

All employees must maintain the confidentiality of material nonpublic information to comply with federal securities laws and for competitive, security and other business reasons. In addition to the prohibition against trading while aware of material nonpublic information or tipping such information to others, federal securities laws prohibit the selective disclosure of material nonpublic information. The Company has, therefore, established procedures for releasing all material nonpublic information in a manner that is designed to achieve broad public dissemination of the information immediately upon its release.

CSX directors, officers and employees should not disclose any material nonpublic information (or any other confidential information) to anyone except persons within the Company or third party agents of the Company (e.g., lawyers, accountants, investments bankers) whose positions or responsibilities require knowledge of the information. Material nonpublic information should not be conveyed to a third party agent until an express understanding has been reached that such information: (i) is not to be used for trading purposes; and (ii) may not be further disclosed except as authorized by the Company. Prior to disclosing such information to a third party agent, please consult with the Law Department to inquire whether a written Confidentiality or Nondisclosure Agreement is required.

The utmost care must be exercised at all times when discussing material nonpublic information. Accordingly, such information should not be discussed in public places, electronic forums, online chatrooms or through unsecure email. To ensure that CSX's confidences are protected to the maximum extent possible, no individuals other than specifically authorized personnel may communicate material information to the public or respond to inquiries from media, analysts or others outside of CSX. Please see the CSX Regulation FD and Corporate Communications Policy for more information.

Notwithstanding anything to the contrary in this policy or otherwise, nothing in Section II.B hereof or any other provision of this Policy or otherwise shall prohibit or impede CSX directors, officers and employees from communicating, cooperating or filing a complaint with any U.S. federal, state or local governmental or law enforcement branch, agency or entity (a "Governmental Entity"), without notifying the Company, with respect to possible violations of any U.S. federal, state or local law or regulation, or otherwise making disclosures to any Governmental Entity, in each case, that are protected under the whistleblower provisions of any such law or regulation, provided that in each case such communications and disclosures are consistent with and protected under the provisions of an applicable whistleblower protection law (collectively, the "Protected Activity"). The Company may not retaliate against CSX directors, officers and employees for any Protected Activity, and nothing in this Agreement requires CSX directors, officers and employees to waive any monetary award or other payment which CSX directors, officers and employees might be entitled to receive from a Governmental Entity in connection with any Protected Activity.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.Restrictions on Trades in Securities of Other Public Companies**

CSX directors, officers and employees may not trade in any security of another public company or any derivative instrument (including, but not limited to, option contracts, swap contracts, warrants and rights) relating thereto while aware of material nonpublic information about that company learned through their employment or position with CSX.

Additionally, CSX directors, officers and employees who know of any such material nonpublic information may not communicate that information to, or tip, any other person, including family members and friends.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.Prohibitions on Hedging and Speculative Transactions Involving CSX Securities and Short Sales**

"Covered Persons" as defined below are prohibited from engaging in any hedging transactions (including transactions involving options, puts, calls, prepaid variable forward contracts, equity swaps, collars and exchange funds or other derivatives) that are designed to hedge or speculate on any change in the market value of CSX securities. Notwithstanding the foregoing, CSX officers and employees may exercise stock options granted by CSX in accordance with this Policy, other Company policies and the terms of the applicable stock option grant.

In addition, such persons may not engage in "short sales" of CSX securities. A "**short sale**" is the sale of securities that are not then owned by the person selling such securities. In other words, the seller borrows and then sells the securities with the hope that the price of the securities will fall and allow the seller to repurchase and return the borrowed securities at a lower price. Thus, a short sale of CSX securities puts the best interests of the Company and its shareholders (i.e., an increase in the price of the security) in conflict with the short seller's potential for personal gain (i.e., a decrease in the price of the security).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E.Pledging of Securities, Margin Accounts**

Pledged securities may be sold by the pledgee without the pledgor's consent under certain conditions. For example, securities held in a margin account may be sold by a broker without the customer's consent if the customer fails to meet a margin call. Because such a sale may occur at a time when an Insider possesses material nonpublic information or is otherwise not permitted to trade in CSX securities, the Company prohibits its directors, officers and employees from pledging CSX securities in any circumstance, including by purchasing CSX securities on margin or holding CSX securities in a margin account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**F.Gifts of Securities** 

As a general matter, gifts of CSX securities, including gifts to charitable organizations, should only be made (i) when an Insider is not in possession of material nonpublic information, (ii) outside of any applicable blackout periods, and (iii) in the case of Covered Persons, after receiving pre-clearance as described in Section III.C hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**G.Restrictions on People and Entities Close to CSX Directors, Officers and Employees**

Except as otherwise agreed to in writing by the Company, this Insider Trading Policy and the procedures herein also apply to the family members of CSX directors, officers and employees and the securities transactions of persons (including corporations, partnerships, other entities, trusts and estates) or accounts over which CSX directors, officers and employees (or such person's family members) exercise investment discretion or control (such as a person's service as an officer or partner of an organization or as a fiduciary of a trust that trades in securities). "**Family members**" means a person's spouse, partner, minor children, adult children primarily dependent for financial support and any relatives living in such person's home.

------

**<u>III. ADDITIONAL PROCEDURES FOR DIRECTORS AND CERTAIN EMPLOYEES</u>**

CSX has adopted the following additional procedures for "**Covered Persons**", who include members of the Board of Directors, executive officers and certain other employees of the Company, as identified by senior management, who regularly may have access to material nonpublic information about the Company. The Office of the Corporate Secretary will inform officers and other employees if they have been designated as a Covered Person for purposes of these additional procedures. This Section continues to apply to former Covered Persons until the later of: (i) the second full trading day following the public release of earnings for the fiscal quarter in which such person leaves CSX or is no longer considered a Covered Person; or (ii) the second full trading day after any material nonpublic information known to such person has become public or is no longer material.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**A.Trading Windows and Blackout Periods**

Covered Persons are generally permitted to engage in transactions in CSX securities outside of the period commencing on the ninth calendar day of the last calendar month of each fiscal quarter through the first trading day following an earnings release (each, a "**blackout period**"). Thus, the trading window runs from the second trading day following an earnings release through the eighth day of the last calendar month of each fiscal quarter. In other words, if the Company issues its earnings release on a Tuesday after the market closes, the trading window would open on Thursday. For purposes of this Policy, "**trading day**" is defined as a day on which the NASDAQ Global Select Market ("**NASDAQ**") is open for trading. Of course, these trading windows are not "safe harbors" that ensure compliance with federal securities laws. Transactions during open trading windows are permitted only if the Covered Person is not aware of any material nonpublic information at the time of the trade.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.Event-Specific Blackout Periods**

From time to time, an event may occur that requires the Senior Vice President - Chief Legal Officer and Corporate Secretary to designate an unplanned blackout period (an "**Event-Specific Blackout Period**") for individuals with knowledge of the event ("**Designated Persons**"). So long as the event remains material and nonpublic, the Designated Persons may not trade in CSX securities. The existence of an Event-Specific Blackout Period shall not be announced other than to those who are aware of the event giving rise to the blackout. Any person made aware of the existence of an Event-Specific Blackout Period shall not disclose the existence of the blackout to any other person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.Pre-Clearance Procedures**

All transactions in CSX securities by a Covered Person must be pre-cleared with the Senior Vice President - Chief Legal Officer and Corporate Secretary or the Assistant Corporate Secretary prior to the transaction; provided, however, that all transactions in CSX securities by a director or the Chief Executive Officer must be pre-cleared with the Senior Vice President - Chief Legal Officer and Corporate Secretary, and transactions by the Senior Vice President - Chief Legal Officer and Corporate Secretary must be pre-cleared with either the Chief Executive Officer or the Chief Financial Officer.

------

**<u>Covered Persons should make their request for pre-clearance using the REQUEST FOR APPROVAL FORM (a copy of which can be obtained through the Office of the Corporate Secretary) at least one business day prior to the date such person wants to trade in order to give sufficient time for review of the request.</u>** A Covered Person's request should indicate the anticipated trading date. As part of the written request, a Covered Person must certify that he or she is not in possession of material nonpublic information about CSX. Pre-clearance of a trade is valid for five full business days, during which time the requested transaction is permitted unless the Covered Person becomes aware of material nonpublic information during that time. For example, if pre-clearance was granted on Thursday prior to the market opening, the pre-clearance would be valid for Thursday and Friday and the following Monday, Tuesday and Wednesday. If pre-clearance is received after the market opens for trading, it will be valid for the following five business days as well as the balance of the trading day on the date of approval. For example, if a Covered Person received pre-clearance at 12:00 p.m. on Thursday, the pre-clearance would be valid for Friday and the following Monday, Tuesday, Wednesday and Thursday, as well the balance of the trading day on the Thursday on which pre-clearance is received. Pre-clearance of a transaction will be made in writing, and such written approval will be filed in the Office of Corporate Secretary. Pre-clearance does not constitute investment advice or guarantee that the transaction complies with federal securities laws.

Covered Persons that are subject to Section 16 of the Securities and Exchange Act of 1934, as amended (the "**Exchange Act**") (i.e., those directors and executive officers who have filed a Form 3 and are required to file Forms 4 and 5), are reminded of their reporting obligations and possible liability to CSX for "short-swing profits" for transactions in CSX stock or options. These pre-clearance procedures will help us to assist Covered Persons in complying with their Section 16 obligations. If you have any questions in this regard, please contact the Office of the Corporate Secretary <u>before</u> buying or selling CSX stock or exercising CSX options.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.Stock Ownership Guidelines**

CSX believes that, in order to align the interests of management and the Board of Directors with those of its shareholders, it is important that the officers and directors hold a meaningful ownership position in CSX common stock relative to their base salary or annual retainer, as applicable. To achieve this alignment, CSX has established the following formal stock ownership guidelines.

---

| | |
|:---|:---|
| **Position** | &nbsp;&nbsp;&nbsp;&nbsp;**Minimum Value** |
| Chief Executive Officer | 6 times base salary |
| Executive Vice Presidents | 4 times base salary |
| Senior Vice Presidents | 3 times base salary |
| Vice Presidents and Equivalent | 1 time base salary |
| Non-management directors | 5 times annual retainer |

---

Officers and directors must retain 100% of their net shares issued until the guidelines are achieved.

------

**<u>IV. RULE 10B5-1 PLANS</u>**

Transactions under a pre-existing written plan, contract, instruction or arrangement under Rule 10b5-1 ("**Rule 10b5-1**") of the Exchange Act (a "**10b5-1 Plan**"), will not be subject to this Insider Trading Policy so long as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.For Covered Persons, the 10b5-1 Plan (and any revision or amendment thereto) has been reviewed and approved by the Senior Vice President - Chief Legal Officer and Corporate Secretary or the Assistant Corporate Secretary (or (i) in the case of members of the Company's Board of Directors or the Chief Executive Officer, the Senior Vice President - Chief Legal Officer and Corporate Secretary, or (ii) in the case of the Senior Vice President - Chief Legal Officer and Corporate Secretary, either (a) the Chief Executive Officer or (b) the Chief Financial Officer);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.For the Company, the 10b5-1 Plan has been reviewed and approved in accordance with the procedures described in Exhibit A hereto;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.For any director or officer of CSX, such plan includes a representation by such director or officer certifying that, on the date of adoption of such plan: (i) the individual director or officer is not aware of any material nonpublic information about the security or CSX; and (ii) the individual director or officer is adopting the plan in good faith and not as part of a plan or scheme to evade the prohibitions of Section 10(b) of the Exchange Act or the rules promulgated thereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.The 10b5-1 Plan (and any revision or amendment thereto) was entered into: (i) (a) in good faith, and was not entered into as part of a plan or scheme to evade the prohibitions of Section 10(b) of the Exchange Act or the rules promulgated thereunder, and (b) by a person acting in good faith with respect to such plan, and (ii) at a time when such person: (a) is not in possession of material nonpublic information about CSX and (b) is not subject to any applicable blackout period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.The 10b5-1 Plan (i) specifies the amount of securities to be purchased or sold and the price at which and the date on which the securities were to be purchased or sold; or (ii) includes a written formula or algorithm, or computer program, for determining the amount of securities to be purchased or sold and the price at which and the date on which the securities were to be purchased or sold; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.The 10b5-1 Plan (and any revision or amendment thereto) (other than any 10b5-1 Plan of CSX) includes a "cooling off" period between the entry into the 10b5-1 Plan and the effectiveness of any trades or transaction pursuant to such plan:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.In the case of directors or officers of CSX, such 10b5-1 Plan specifies that trades may not execute under the 10b5-1 Plan until the later of (a) 90 days after the date of adoption or amendment of the 10b5-1 Plan and (b) 2 business days following CSX's filing of a quarterly or annual report covering the financial reporting period in which the 10b5-1 Plan was adopted or amended, but not later than 120 days after the date of adoption or amendment of the 10b5-1 Plan; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.In the case of all others (other than CSX) entering into a 10b5-1 Plan, such 10b5-1 Plan specifies that trades may not execute under the 10b5-1 Plan for a period of at least 30 days after the date of adoption or amendment of the 10b5-1 Plan.

------

An Insider may have only one 10b5-1 Plan in effect at any time, except that a written, irrevocable election (an "**Election**") by such Insider to sell a portion of shares as necessary to satisfy statutory tax withholding obligations arising solely from the vesting of compensatory awards (not including options) ("**Sales to Cover**") is permitted, provided that (a) the Election is not made during any applicable blackout period, (b) at the time of the Election, the Insider is not aware of any material nonpublic information about CSX, (c) the Sales to Cover are made in good faith and not as part of a plan or scheme to evade the prohibitions of Section 10(b) of the Exchange Act or the rules promulgated thereunder, (d) the Insider does not have, and will not attempt to exercise, authority, influence or control over any such Sales to Cover, and (e) the Election contains appropriate representations as to clauses (b)-(d).

An Insider may adopt a new 10b5-1 Plan to replace an existing 10b5-1 Plan before the scheduled termination date of such existing 10b5-1 Plan, so long as the first scheduled trade under the new 10b5-1 Plan does not occur until after all trades under the existing 10b5-1 Plan are completed or expire without execution (subject to any cooling-off periods described in clause 6 above). A series of separate contracts with different brokers to execute trades under a 10b5-1 Plan may be treated as a single plan, provided the contracts as a whole meet the conditions under Rule 10b5-1, and provided further that any amendment of one contract is treated as an amendment of all of the contracts under the plan.

In any 12-month period, an Insider is limited to one "single-trade plan" — one designed to effect the open market purchase or sale of the total amount of the securities subject to the plan as a single transaction. The following do not constitute single-trade plans: (a) a 10b5-1 Plan that gives discretion to an agent over whether to execute the 10b5-1 Plan as a single transaction or that provides the agent's future acts depend on facts not known at the time the 10b5-1 Plan's adoption and might reasonably result in multiple transactions and (b) Sales to Cover.

A 10b5-1 Plan may only be suspended or terminated (i) outside of any applicable blackout period, (ii) at a time when such person is not in possession of material nonpublic information about CSX and (iii) in the case of Covered Persons, after receiving pre-clearance as described in Section III.C hereof.

**CSX TRADING POLICIES AND PROCEDURES**

These policies and procedures govern repurchases of CSX equity securities ("**Repurchases**") approved from time to time by the Board of Directors (the "**Board**") of CSX to help ensure that such Repurchases are not made, or a share repurchase plan is not adopted, when CSX is in possession of material nonpublic information concerning CSX ("**MNPI**"). Capitalized terms used but not defined herein have the respective meanings given to them in CSX's Insider Trading Policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.*Policy*. It is CSX's policy that no Repurchases may take place inside a blackout period or when CSX is otherwise in possession of MNPI, other than Repurchases made pursuant to a 10b5-1 Plan or otherwise in compliance with applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.*Trading Activity*. Any Repurchases, or the adoption of a 10b5-1 Plan to effect Repurchases, shall be subject to the following procedures:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.The adoption of a 10b5-1 Plan (and any revision or amendment thereto) shall be subject to prior written approval by the Senior Vice President - Chief Legal Officer and Corporate Secretary and the Executive Vice President – Chief Financial Officer. Each of the foregoing officers shall take such steps as he or she deems reasonably necessary to ascertain that CSX is not in possession of MNPI at the time of plan adoption, including but not limited to consulting with other members of senior management (each, an "**Authorized Officer**") and/or legal counsel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.With respect to Repurchases that have been approved by the Board, if at any time during the period such Repurchases are scheduled to take place, the Senior Vice President - Chief Legal Officer and Corporate Secretary or any Authorized Officer become aware of any MNPI, they shall notify the relevant employee(s) at CSX responsible for effecting Repurchases as soon as practicable to suspend such Repurchases.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.Once the Senior Vice President - Chief Legal Officer and such Authorized Officer are satisfied that, to their knowledge, CSX is no longer in possession of MNPI, they shall notify the relevant employee(s) that CSX may resume its Repurchases.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.*Recordkeeping*. The Senior Vice President - Chief Legal Officer and Corporate Secretary and Executive Vice President – Chief Financial Officer, or their designees, shall maintain a record of the communications referred to in these policies and procedures in compliance with CSX's recordkeeping policies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.*Training*. CSX directors, officers and employees who are involved in CSX's securities trading activities shall be provided training on the Trading Policy and these policies and procedures consistent with CSX's employee training policies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.*Modification or Waiver*. These policies and procedures may be modified, and specific requirements therein may be waived, subject to approval by the Senior Vice President - Chief Legal Officer and Corporate Secretary if such modifications or waivers are appropriate based on particular facts and circumstances, and in compliance with applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.*Amendments*. These policies and procedures will be reviewed periodically as determined by the Senior Vice President - Chief Legal Officer and Corporate Secretary.
