ITEM 1A. RISK FACTORS

The risks set forth in the following risk factors could have a materially adverse effect on the Company's business, financial condition, results of operations, and liquidity, and could cause those results to differ materially from those expressed or implied in the Company's forward-looking statements and forward-looking information (collectively, "forward-looking statements").

The information set forth in this Item 1A. Risk Factors should be read in conjunction with the rest of the information included in this annual report, including Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations and Item 8. Financial Statements and Supplementary Data.

Business and Operational Risks

As a common carrier, the Company is required by law to transport dangerous goods and hazardous materials, which could expose the Company to significant costs and claims.Railways, including the Company, are legally required to transport dangerous goods and hazardous materials as part of their common carrier obligations regardless of risk or potential exposure to loss. The Company transports dangerous goods and hazardous materials, including but not limited to crude oil, ethanol, and TIH materials such as chlorine gas and anhydrous ammonia. A train accident involving hazardous materials could result in significant claims against the Company arising from personal injury, property or natural resource damage, environmental penalties, and remediation obligations. Such claims, if insured, could exceed the existing insurance coverage commercially available to the Company, which could have a material adverse effect on the Company’s financial condition, operating results, and liquidity. The Company is also required to comply with rules and regulations regarding the handling of dangerous goods and hazardous materials across its network. Noncompliance with these rules and regulations can subject the Company to significant penalties and could factor in litigation arising out of a train accident. Changes to these rules and regulations could also increase operating costs, reduce operating efficiencies and impact service delivery.

The Company faces competition from other transportation providers and failure to compete effectively could adversely affect financial results.The Company faces significant competition for freight transportation across its network, including competition from other railways, motor carriers, ship and barge operators, and pipelines. Competition is based mainly on quality of service, freight rates, and access to markets. Other transportation modes generally use public rights-of-way that are built and maintained by government entities, while the Company and other railways must use internal resources to build and maintain their rail networks. Competition with the trucking industry is generally based on freight rates, flexibility of service, and transit time performance. Any future improvements or expenditures materially increasing the quality or reducing the cost of alternative modes of transportation, or legislation that eliminates or significantly reduces the burden of the size or weight limitations currently applicable to trucking carriers, could have a material adverse effect on the Company's financial results.

The operations of carriers with which the Company interchanges may adversely affect operations. The Company's ability to provide rail services to customers across its network also depends upon its ability to maintain cooperative relationships with connecting carriers with respect to, among other matters, revenue division, car supply and locomotive availability, data exchange and communications, reciprocal switching, interchange, and trackage rights. Deterioration in the operations or services provided by connecting carriers, or in the Company's relationship with those connecting carriers, could result in the Company's inability to meet customers' demands or require the Company to use alternate train routes, which could result in significant additional costs and network inefficiencies and adversely affect our business, operating results, and financial condition.

The Company may be affected by acts of terrorism, war, or risk of war.The Company plays a critical role in the North American transportation system and therefore could become the target for acts of terrorism or war. The Company is also involved in the transportation of hazardous materials, which could result in the Company's equipment or infrastructure being direct targets or indirect casualties of terrorist attacks. Acts of terrorism, or other similar events, any government response thereto, and war or risk of war could cause significant business interruption to the Company and may adversely affect the Company’s results of operations, financial condition and liquidity.

The Company is affected by fluctuating fuel prices.Fuel expense constitutes a significant portion of the Company’s operating costs. Fuel prices can be subject to dramatic fluctuations, and significant price increases could have a material adverse effect on the Company's results of operations. The Company currently employs a fuel cost adjustment program to help reduce volatility in changing fuel prices, but the Company cannot be certain that it will always be able to fully mitigate rising or elevated fuel prices through this program. Factors affecting fuel prices include worldwide oil demand, international geopolitics, weather, refinery capacity, supplier and upstream outages, unplanned infrastructure failures, environmental and sustainability policies, and labour and political instability.

The Company relies on technology and technological improvements to operate its business. Although the Company devotes significant resources to protect its technology systems and proprietary data, there can be no assurance that the systems we have designed to prevent or limit the effects of cyber incidents or attacks will be sufficient in averting such incidents or attacks. (Please see “Item 1C. Cybersecurity” for further discussion). The Company continually evaluates attackers’ techniques, tactics and motives, and strives to be diligent in its monitoring, training, planning, and prevention. However, due to the increasing sophistication of cyber-attacks and greater complexity within our IT supply chain, the Company may be unable to anticipate or implement appropriate preventive measures to detect and respond to a security breach.

CPKC 2023 ANNUAL REPORT / 17

This includes the rising rates of reported ransomware events, human error, or other cyber-attack methods disrupting the Company’s systems or the systems of third parties. If the Company or third parties whose technology systems we rely on were to experience a significant disruption or failure of one or more of their information technology or communications systems (either as a result of an intentional cyber or malicious act, or an unintentional error), it could result in significant service interruptions, safety failures or other operational difficulties such as: unauthorized access to confidential or other critical information or systems, loss of customers, financial losses, regulatory fines, and misuse or corruption of critical data and proprietary information, which could have a material adverse effect on the Company's results of operations, financial condition, and liquidity. The Company also may experience security breaches that could remain undetected for an extended period and, therefore, have a greater impact on the services we offer. In addition, if the Company is unable to acquire or implement new technology in general, the Company may suffer a competitive disadvantage, which could also have an adverse effect on its results of operations, financial condition, and liquidity.

Human Capital Risks

The availability of qualified personnel could adversely affect the Company's operations.Changes in employee demographics, training requirements and the availability of qualified personnel, particularly locomotive engineers and trainpersons, could negatively impact the Company’s ability to meet demand for rail services. Unpredictable increases in the demand for rail services may increase the risk of having insufficient numbers of trained personnel, which could have a material adverse effect on the Company’s results of operations, financial condition and liquidity. In addition, changes in operations and other technology improvements may significantly impact the number of employees required to meet the demand for rail services.

Strikes or work stoppages adversely affect the Company's operations.Class I railways are party to collective bargaining agreements with various labour unions. The majority of the Company's employees belong to labour unions and are subject to these agreements. Disputes with regard to the terms of these agreements or the Company's potential inability to negotiate mutually acceptable contracts with these unions, have resulted in, and could in the future result in, among other things, strikes, work stoppages, slowdowns, or lockouts, which could cause a significant disruption of the Company's operations and have a material adverse effect on the Company's results of operations, financial condition, and liquidity. Additionally, future national labour agreements, or provisions of labour agreements related to health care, could significantly increase the Company's costs for health and welfare benefits, which could have a material adverse impact on its financial condition and liquidity.

Legal and Regulatory Risks

The Company is subject to significant governmental legislation and regulation over commercial, operating and environmental, climate, sustainability and other matters.The Company’s railway operations are subject to extensive federal laws, regulations and rules in the countries it operates. Operations are subject to economic and safety regulations in Canada primarily by the Agency and TC. The Company’s U.S. operations are subject to economic and safety regulation by the STB and the FRA. The Company’s Mexican operations are subject to economic and safety regulations by the SICT and ARTF. Any new rules from regulators 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. Various other regulators, including the FRA, and its sister agency within the U.S. Department of Transportation, the PHMSA, directly and indirectly affect the Company’s operations in areas such as health, safety, security, environmental and other matters. Together, the FRA and the 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. Additional regulation of the rail industry by these regulators or federal and state or provincial legislative bodies, whether under new or existing laws, may result in increased capital expenditures and operating costs and could have a significant negative impact on the Company’s ability to determine prices for rail services and result in a material adverse effect in the future on the Company’s business, financial position, results of operations, and liquidity in a particular year or quarter. This potential material adverse effect could also result in reduced capital spending on the Company’s rail network or in abandonment of lines.

The Company is subject to environmental laws and regulations that may result in significant costs. The Company’s operations are subject to extensive federal, state, provincial (Canada) and local environmental laws and regulations, including those governing air pollutants, GHG emissions, management and remediation of historical contaminant sites, discharges to waters and the handling, storage, transportation, and disposal of waste and other materials. (Please see “Environmental Laws, Regulations and Strategies” and “Sustainability-Related Laws, Regulations and Strategies” in Item 1. Business for further discussion). Violation of these laws and regulations can result in significant fines and penalties, as well as other potential impacts on the Company’s operations. These laws can impose strict, and in some circumstances, joint and several liability on both current and former owners, and on operators of facilities. If the Company is found to have violated such laws or regulations or to have acted in a manner that is inconsistent with regulatory expectations, such a finding could have a material adverse effect on the Company’s business, financial condition, or operating results.

Such environmental liabilities may also be raised by adjacent landowners or third parties. In addition, in operating a railway, it is possible that releases of hazardous materials during derailments or other accidents may occur that could cause harm to human health or to the environment. Costs of remediation, damages and changes in regulations could materially affect the Company’s operating results and reputation. 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. The Company currently has obligations at existing sites for investigation, remediation and monitoring, and will likely have obligations at other sites in the future. The actual costs associated with both current and long-term liabilities may vary from the Company’s estimates due to a number of factors including, but not limited to changes in: the content or interpretation of environmental laws and regulations; required remedial actions; technology associated with site

18 / CPKC 2023 ANNUAL REPORT

investigation or remediation; and the involvement and financial viability of other parties that may be responsible for portions of those liabilities. The Company’s Mexican operations are subject to Mexican federal and state laws and regulations relating to the protection of the environment concerning, among other matters, emissions to the air, land, and water, and the handling of hazardous materials and wastes, and are also subject to the compliance with standards for water discharge, water supply, emissions, noise pollution, hazardous substances and transportation and handling of hazardous and solid waste. The Mexican government may bring administrative and criminal proceedings, impose economic sanctions against companies that violate environmental laws, and temporarily or even permanently close non-complying facilities.

The Company is subject to claims and litigation that could result in significant expenditures. Due to the nature of its operations, the Company is exposed to the potential for claims and litigation arising out of personal injury, property damage or freight damage, employment, labour contract or other commercial disputes, and environmental, climate or sustainability, or other liability. The Company accrues for potential losses in accordance with applicable accounting standards, based on ongoing assessments of the likelihood of an adverse result in a claim or litigation together with the monetary relief or other damages sought or potentially recoverable. Material changes to litigation trends, a significant rail or other incident or series of incidents involving freight damage or loss, property damage, personal injury, or environmental, climate or sustainability, or other liability, and other significant matters could have a material adverse impact to the Company's operations, reputation, financial position or liquidity.

Supply Chain Risks

Disruptions within the supply chain could negatively affect the Company's operational efficiencies and increase costs.The North American transportation system is integrated. The Company’s operations and service may be negatively impacted by service disruptions of other transportation links, such as ports, handling facilities, customer facilities, and other railways. A prolonged service disruption at one of these entities could have a material adverse effect on the Company's results of operations, financial condition, and liquidity.

The Company is dependent on certain key suppliers of core railway equipment and materials that could result in increased price volatility or significant shortages of materials, which could adversely affect results of operations, financial condition, and liquidity.Due to the complexity and specialized nature of core railway equipment and infrastructure (including rolling stock equipment, locomotives, rail and ties), there are a limited number of suppliers of rail equipment and materials available. Should these specialized suppliers cease production or experience capacity or supply shortages, this concentration of suppliers could result in the Company experiencing cost increases or difficulty in obtaining rail equipment and materials, which could have a material adverse effect on the Company's results of operations, financial condition, and liquidity. Additionally, the Company’s operations are dependent on the availability of diesel fuel. A significant fuel supply shortage arising from production decreases, increased demand in existing or emerging foreign markets, disruption of oil imports, disruption of domestic refinery production, damage to refinery or pipeline infrastructure, political unrest, war or other factors could have a material adverse effect on the Company's results of operations, financial position, and liquidity in a particular year or quarter.

Risks Related to the Kansas City Southern Transaction

The conditions imposed by the STB’s March 15, 2023 final decision could have an adverse effect on the Company’s businesses, results of operations, financial condition, cash flows or the market value of the Company’s common stock and debt securities, or reduce the anticipated benefits of the combination. In connection with the STB's March 15, 2023 final decision, the STB imposed a number of conditions, including among others (i) commitments by the combined company to keep gateways open on commercially reasonable terms and create no new bottlenecks, (ii) environmental-related conditions, (iii) data reporting and retention requirements, and (iv) a seven-year oversight period for the STB to monitor adherence to these conditions. In addition, the Company inherits conditions previously imposed by the STB on KCS in connection with various prior KCS acquisitions, including in relation to KCS’s commitment to keep the Laredo gateway open on commercially reasonable terms in connection with its prior acquisition of The Texas Mexican Railway. Furthermore, the STB has noted its authority to issue supplemental orders to address issues or concerns that may arise in the future. These conditions could disrupt the Company’s businesses, and uncertainty about the outcome of that review could divert management’s attention and resources, and reduce the anticipated benefits of the combination, and may have an adverse effect on the combined company. Further, the combination may give rise to potential liabilities, including as a result of pending and future shareholder lawsuits and other litigation relating to the combination. In addition, the Company has incurred, and expects to incur additional, material non-recurring expenses in connection with the completion of the combination and integration activities. Any of these matters could adversely affect the businesses of, or harm the results of operations, financial condition or cash flows of the Company and the market value of the Company’s common stock and debt securities.

The Company incurred substantial indebtedness in connection with consummation of the acquisition, which may pose risks and/or intensify existing risks. Prior to the KCS acquisition closing into voting trust that occurred on December 14, 2021, the Company incurred additional indebtedness of approximately U.S. $6.7 billion and $2.2 billion notes to indirectly fund the acquisition.

The foregoing indebtedness, as well as any additional indebtedness we may incur, could have the effect, among other things, of reducing our liquidity and may limit our flexibility in responding to other business opportunities and increasing our vulnerability to adverse economic and industry conditions.

Our ability to make payments of principal and interest on our indebtedness depends upon our future performance, which will be subject to general economic, financial and business conditions, and other factors affecting our operations, many of which are beyond our control. In addition, we may be

CPKC 2023 ANNUAL REPORT / 19

required to redeem all of the outstanding 2.450% notes due 2031 and 3.000% notes due 2041 pursuant to a special mandatory redemption requirement of those notes, which could have a significant adverse impact on the business and financial condition of the Company.

Our increased indebtedness could also reduce funds available for working capital, capital expenditures, acquisitions and other general corporate purposes and may create competitive disadvantages relative to other companies with lower debt levels. If we do not achieve the expected benefits and cost savings from the combination, or if the financial performance of the combined company does not meet current expectations, then our ability to service our indebtedness may be adversely impacted.

The agreements that govern the indebtedness that has been incurred in connection with the KCS acquisition contain various affirmative and negative covenants that may, subject to certain customary exceptions, restrict our ability to, among other things, create liens over our property, change our line of business and/or merge or consolidate with any other person or sell or convey certain of our assets to another person. In addition, some of the agreements that govern our debt financings contain a financial covenant that requires us to maintain certain financial ratios. Various risks, uncertainties and events beyond our control could affect our ability to comply with these covenants and failure to comply with them could result in an event of default, which, if not cured or waived, could accelerate our repayment obligations. Under these circumstances, we may not have sufficient funds or other resources to satisfy all of our obligations.

Moreover, we may be required to raise substantial additional financing to fund working capital, capital expenditures, acquisitions or other general corporate requirements. Our ability to arrange additional financing or refinancing will depend on, among other factors, our financial position and performance, as well as prevailing market conditions and other factors beyond our control. There can be no assurance that we will be able to obtain additional financing or refinancing on terms acceptable to us or at all.

The Company may be unable to integrate KCS successfully, and the Company may not experience the growth being sought from the combination. CPRL and KCS operated independently until the Control Date. Integrating KCS with CPKC will involve operational, technological and personnel-related challenges. This process is time-consuming and expensive, may disrupt the businesses of either or both of the companies and may reduce the growth opportunities sought from the combination. There can be no guarantee of the successful integration of KCS or that the combined company will realize the anticipated benefits of the business combination, whether financial, strategic or otherwise, and this may be exacerbated by changes to the economic, political and global environment in which the merged company would operates.

Risks related to Operations in Mexico

The Mexican concession of CPKCM is subject to revocation or termination in certain circumstances, which would prevent CPKCM from conducting rail operations under the Concession and would have a material adverse effect on the Company’s consolidated financial statements. CPKCM operates under the Concession granted by the Mexican government for a period of 50 years which is renewable under certain conditions for additional periods, each of up to 50 years. The Concession gives CPKCM exclusive rights to provide freight transportation services over its rail lines through 2037 (the first 40 years of the 50-year Concession), subject to certain trackage and haulage rights granted to other freight rail concessionaires, and subject to trackage and haulage rights afforded to concessionaires of concessions that may be granted by the SICT to provide passenger rail service in the future.

The SICT and ARTF, which are principally responsible for regulating railroad services in Mexico, have broad powers to monitor CPKCM’s compliance with the Concession, and they can require CPKCM to supply them with any technical, administrative and financial information they request. Among other obligations, CPKCM must comply with the investment commitments established in its business plan, which forms an integral part of the Concession, and must update the plan every three years. The SICT treats CPKCM’s business plans confidentially. The SICT and ARTF also monitor CPKCM’s compliance with efficiency and safety standards established in the Concession. The SICT and ARTF review, and may amend, these standards from time to time. COFECE also has the authority to regulate railroad service in Mexico, having powers to monitor compliance with the antitrust laws as well as to investigate and determine remedies for anticompetitive practices.

Under the Concession, CPKCM has the right to operate its rail lines, but it does not own the land, roadway or associated structures. If the Mexican government legally terminates the Concession, it would own, control, and manage such public domain assets used in the operation of CPKCM’s rail lines. All other property not covered by the Concession, including all locomotives and railcars otherwise acquired, would remain CPKCM’s property. In the event of early termination, or total or partial revocation of the Concession, the Mexican government would have the right to cause the Company to lease all service related assets to it for a term of at least one year, automatically renewable for additional one-year terms for up to five years. The amount of rent would be determined by experts appointed by CPKCM and the Mexican government. The Mexican government must exercise this right within four months after early termination or revocation of the Concession.

In addition, the Mexican government would also have a right of first refusal with respect to certain transfers by CPKCM of railroad equipment within 90 days after revocation of the Concession. The Mexican government may also temporarily seize control of CPKCM’s rail lines and its assets in the event of a natural disaster, war, significant public disturbance or imminent danger to the domestic peace or economy. In such a case, the SICT may restrict CPKCM’s ability to operate under the Concession in such manner as the SICT deems necessary under the circumstances, but only for the duration of any of the foregoing events. Mexican law requires that the Mexican government pay compensation if it effects a statutory appropriation for reasons of the public

20 / CPKC 2023 ANNUAL REPORT

interest. With respect to a temporary seizure due to any cause other than international war, the Mexican Regulatory Railroad Service Law and regulations provide that the Mexican government will indemnify an affected concessionaire for an amount equal to damages caused and losses suffered. However, these payments may not be sufficient to compensate CPKCM for its losses and may not be made timely.

The SICT may revoke the Concession if CPKCM is sanctioned for the same cause at least three times within a period of five years for any of the following: unjustly interrupting the operation of its rail lines or rendering its public services for charging rates higher than those it has registered with the ARTF; unlawfully restricting the ability of other Mexican rail operators to use its rail lines; failing to make payments for damages caused during the performance of services; failing to comply with any term or condition of the Mexican Regulatory Railroad Service Law and regulations or the Concession; failing to make the capital investments required under its three-year business plan filed with the SICT; or failing to maintain an obligations compliance bond and insurance coverage as specified in the Mexican Regulatory Railroad Service Law and regulations. In addition, the Concession would terminate automatically if CPKCM changes its nationality or assigns or creates any lien on the Concession, or if there is a change in control of CPKCM without the SICT’s approval.

The SICT may also terminate the Concession as a result of CPKCM’s surrender of its rights under the Concession, or for reasons of public interest or upon CPKCM’s liquidation or bankruptcy. If the Concession is terminated or revoked by the SICT for any reason, CPKCM would receive no compensation and its interest in its rail lines, and all other fixtures covered by the Concession, as well as all improvements made by it, would revert to the Mexican government. Revocation or termination of the Concession could have a material adverse effect on the Company’s consolidated financial statements.

The Company’s ownership of CPKCM and operations in Mexico subject it to Mexican economic and political risks. The Mexican government has exercised, and continues to exercise, significant influence over the Mexican economy. Accordingly, Mexican governmental actions concerning the economy and state-owned enterprises could have a significant impact on Mexican private sector entities in general and on CPKCM’s operations in particular. For example, CPKCM operations could be impacted with the introduction of new legislation or policies to regulate the railway industry, the energy market, or labour and tax conditions. The Company cannot predict the impact that the political landscape, including multiparty rule, social unrest and civil disobedience, will have on the Mexican economy or CPKCM’s operations. For example, from time to time, teachers' protests in Mexico have resulted in service interruptions on CPKCM’s right of ways. The Company’s consolidated financial statements and prospects may be adversely affected by currency fluctuations, inflation, interest rates, regulation, taxation and other political, social and economic developments in or affecting Mexico. For example, the Company has a tax contingency related to an audit assessment, which is currently in litigation, for the CPKCM 2014 Mexico tax return. An adverse resolution of these matters could have a material adverse effect on the Company’s consolidated financial statements in a particular quarter or period. Tax contingencies are further discussed in Notes 6 and 26 of Item 8. Financial Statements and Supplementary Data.

The social and political situation in Mexico could adversely affect the Mexican economy and CPKCM’s operations, and changes in laws, public policies and government programs could be enacted, each of which could also have a material adverse effect on the Company’s consolidated financial statements.

The Mexican economy in the past has suffered balance of payment deficits and shortages in FX reserves. Although Mexico has imposed foreign exchange controls in the past, there are currently no exchange controls in Mexico. Any restrictive exchange control policy could adversely affect the Company’s ability to obtain U.S. dollars or to convert Mexican pesos into dollars for purposes of making payments. This could have a material adverse effect on the Company’s consolidated financial statements.

Downturns in the United States economy or in trade between the United States and Asia or Mexico and fluctuations in the peso-dollar exchange rates could have material adverse effects on the Company’s consolidated financial statements. The level and timing of the Company’s Mexican business activity is heavily dependent upon the level of United States-Mexican trade and the effects of current or future multinational trade agreements on such trade. The Mexican operations depend on the United States and Mexican markets for the products CPKCM transports, the relative position of Mexico and the United States in these markets at any given time, and tariffs or other barriers to trade. Failure to preserve trade provisions conducive to trade, or any other action imposing import duties or border taxes, could negatively impact KCS customers and the volume of rail shipments, and could have a material adverse effect on the Company’s consolidated financial statements.

Downturns in the United States or Mexican economies or in trade between the United States and Mexico could have material adverse effects on the Company’s consolidated financial statements and the Company’s ability to meet debt service obligations. In addition, the Company has invested significant amounts in developing its intermodal operations, including the Port of Lázaro Cárdenas, in part to provide Asian importers with an alternative to the west coast ports of the United States, and the level of intermodal traffic depends, to an extent, on the volume of Asian shipments routed through Lázaro Cárdenas. Reductions in trading volumes, which may be caused by factors beyond the Company’s control, including increased government regulations regarding the safety and quality of Asian-manufactured products, could have a material adverse effect on the Company’s consolidated financial statements.

Additionally, fluctuations in the peso-dollar exchange rates could lead to shifts in the types and volumes of Mexican imports and exports. Although a decrease in the level of exports of some of the commodities that CPKCM transports to the United States may be offset by a subsequent increase in imports of other commodities CPKCM hauls into Mexico and vice versa, any offsetting increase might not occur on a timely basis, if at all. Future developments in

CPKC 2023 ANNUAL REPORT / 21

United States-Mexican trade beyond the Company’s control may result in a reduction of freight volumes or in an unfavourable shift in the mix of products and commodities CPKCM carries.

Extreme volatility in the peso-dollar exchange rate may result in disruption of the international foreign exchange markets and may limit the ability to transfer or convert Mexican pesos into U.S. dollars. Although the Mexican government currently does not restrict, and for many years has not restricted, the right or ability of Mexican or foreign persons or entities to convert pesos into U.S. dollars or to transfer foreign currencies out of Mexico, the Mexican government could, as in the past, institute restrictive exchange rate policies that could limit the ability to transfer or convert pesos into U.S. dollars or other currencies for the purpose of making timely payments and meeting contractual commitments. Fluctuations in the peso-dollar exchange rates also have an effect on the Company’s consolidated financial statements. A weakening of the peso against the U.S. dollar would cause reported peso-denominated revenues and expenses to decrease, and could increase reported foreign exchange loss due to the Company’s net monetary assets that are peso-denominated. Exchange rate variations also affect the calculation of taxes under Mexican income tax law, and a weakening of the peso against the U.S. dollar could cause an increase in the Company’s cash tax obligation and effective income tax rate.

Climate-Related Risks

Climate change presents both physical and transition risks to our business. A summary of climate-related risks that could adversely affect our business, operations and financial results is discussed below.

Physical Risks

Changing climate conditions, severe weather or natural disasters could result in significant business interruptions and costs to the Company. The Company is exposed to severe weather conditions and natural disasters, including earthquakes, volcanism, hurricanes, tropical storms, tornadoes, floods, fires, avalanches, mudslides, extreme temperatures, and significant precipitation have caused track outages, severe damage to infrastructure, and business interruptions that have adversely affected the Company’s entire rail network. These events have resulted and can result in substantial costs to respond during the event and recover following the event. Costs can include modifications to existing infrastructure or implementation of new infrastructure to prevent future impacts to our business.

Impacts from these types of events are highly variable based on the severity and length of the event and scope of network impact. Climate-related changes such as rising mean temperatures and severe weather events can increase physical climate risk potentially compounding impacts to the business and operations. Such events have had and in the future could have a material adverse effect on the Company’s results of operations, financial condition, and liquidity.

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 may not continue to be available at commercially reasonable rates. Even with insurance, if any natural occurrence leads to a catastrophic interruption of services, the Company may not be able to restore services without a significant interruption in operations.

Transition Risks

Reputational Risks

The Company has established a GHG emissions reduction target, and may establish updated or new targets in the future to guide the implementation of the Company's carbon reduction efforts. The Company's inability to achieve the current GHG emissions reduction target or any future targets we may establish could negatively impact the Company, including both our reputation and financial results. The Company has established a science-based GHG emissions reduction target (please see “Sustainability-Related Laws, Regulations and Strategies—Climate Change” in Item 1. Business for further discussion). Our current GHG emissions reduction target and any future GHG emissions reduction targets we may establish are subject to a number of risks, assumptions and uncertainties that include, but are not limited to: changes in carbon markets; evolving sustainability strategies and scientific, methodological or technological developments, including future investments in and the availability of GHG emissions-reduction tools and technologies, shifts in the science, data, methodology and legal and financial considerations underlying our climate and sustainability-related analysis and strategy, including those developed and used by organizations such as SBTi, the ability of the Company to successfully implement its climate and sustainability-related strategies and initiatives (including actions and plans undertaken by the Company to reduce GHG emissions), significant changes in the Company's GHG emissions profile as a result of changes to its railway asset base, the Company's ability to work with governments and third parties to mitigate the impacts of climate change, domestic and international economic conditions, including exchange rates, the effects of competition and regulation, uncertainties in the financial markets, capital spending, actions of vendors, the willingness of customers to acquire our services, cost of network expansion, maintenance and retrofits, and physical impact of climate change on our business. In addition, the accuracy, consistency and usefulness of climate or sustainability-related data (including data underlying our current or future targets and their baselines) could be impacted by a number of factors, including the accuracy of the assumptions in the science-based methodology used to calculate this data, improvement in our data collection and measuring systems, activities such as joint ventures, mergers and acquisitions or divestitures, and industry-driven changes to methodologies. Further, as we continue to integrate KCS, we are conducting additional data-gathering and intend to further assess the climate and sustainability strategies and initiatives for the combined company, and may make changes to our existing strategies and initiatives as a result.

22 / CPKC 2023 ANNUAL REPORT

As a result of these and other factors, we may not achieve our current GHG emissions reduction target or any future GHG emissions reduction targets we may establish. We cannot assure that the Company's current or future plans to reduce GHG emissions will be viable or successful. Inability to meet our current GHG emissions reduction target or any future GHG emissions reduction targets we may establish, including our ability do so in a manner that meets standards and expectations developed by third parties such as SBTi, could have a material adverse effect on the Company's reputation, legal risks, results of operations, and financial position.

Policy and Regulatory Risks

An escalating price on carbon emissions could materially increase direct costs related to fuel purchases and indirect expenses related to purchased goods, materials, and electricity required to operate our business. As a fuel-intensive operation, the Company is exposed to both emerging and escalating carbon pricing regulations. The Company is regulated under multiple carbon taxation systems and cap and trade market mechanisms in the Canadian provinces in which we operate. The Company's Scope 1 and Scope 2 GHG emissions generated through our operations in Canada and Mexico are impacted by carbon pricing mechanisms.

The Company is further exposed to carbon pricing through electricity purchases, where electric utilities pass on carbon costs to customers. Introduction of, or changes to, regulations by government bodies in response to climate change that increase the cost of carbon emissions could result in a significant increase in expenses and could adversely affect our business performance, results of operations, financial position, and liquidity.

Please see “Sustainability-Related Laws, Regulations and Strategies” in Item 1. Business for further discussion of climate- and other sustainability-related laws and regulations (including the rulemaking activities of securities regulatory authorities in Canada and the United States) that could materially affect the Company’s operating results, financial condition, and reputation.

Market Risks

A number of the sectors the Company serves have the potential to be significantly impacted by climate-related transitional risks, including increased regulations, technology changes, and shifts in consumer preferences. The Company’s business is based on transporting a wide variety of commodities from suppliers to the marketplace. The Company regularly transports energy commodities that serve refineries, processing locations, and end-users across North America and global markets. The Company’s business lines include thermal and metallurgical coal, crude oil and petroleum products, including liquefied petroleum gas, fuel oil, asphalt, gasoline, condensate (diluent), and lubricant oils.

Shifting consumer demand to lower-carbon products and increased climate-focused regulations, such as carbon pricing and fuel regulations, may instigate a broad transition in the energy sector. Programs that place a price on carbon emissions or other government restrictions on certain market sectors may further impact current and potential freight rail customers in the energy sector. A comprehensive transition in the energy sector could significantly impact the markets of the Company's energy customers or lead to market differentiation through geographic variation in policies and demand trends. A portion of the Company’s business could be materially affected by potential future changes and instability that may be related to such a transition.

Please see “Sustainability-Related Laws, Regulations and Strategies” in Item 1. Business for further discussion of climate- and other sustainability-related laws, regulations and other legal developments that could materially affect the preferences, activities, and financial conditions of our customers and other stakeholders, as well as the Company’s operating results, financial condition, and reputation.

General Risk Factors

Global Risks

Global economic and public health conditions could negatively affect demand for commodities and other freight transported by the Company. A decline or disruption in domestic, cross border or global economic conditions, including fluctuations in interest rates, that affect the supply or demand for the commodities that the Company transports may decrease the Company’s freight volumes and would result in a material adverse effect on the Company’s financial or operating results and liquidity. Economic conditions resulting in bankruptcies of one or more large customers could have a significant impact on the Company's financial position, results of operations, and liquidity in a particular year or quarter. We are also subject to outbreaks of infectious disease, such as risks related to the global COVID-19 pandemic, which had adverse impacts on economic and market conditions and the Company's business. Public health crises, including COVID-19, have created, and in the future may create, significant volatility, uncertainty and economic disruption in the regions in which the Company operates and therefore adversely affect the Company's business.

Liquidity Risks

The state of capital markets could adversely affect the Company's liquidity. Weakness in the capital and credit markets could negatively impact the Company’s access to capital. From time to time, the Company relies on the capital markets to provide some of its capital requirements, including the issuance of long-term debt instruments and commercial paper. Significant instability or disruptions of the capital markets and the credit markets, or deterioration of the Company's financial condition due to internal or external factors could restrict or eliminate the Company's access to, and/or significantly increase the cost of, various financing sources, including bank credit facilities and issuance of corporate bonds. Instability or disruptions of the capital markets and deterioration of the Company's financial condition, alone or in combination, could also result in a reduction in the Company's

CPKC 2023 ANNUAL REPORT / 23

credit rating to below investment grade, which could also further prohibit or restrict the Company from accessing external sources of short-term and long-term debt financing, and/or significantly increase the associated costs.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 1C. CYBERSECURITY

Risk Management

CPKC’s cybersecurity risk management program is an integrated and essential component of the Company’s overall risk management strategy. Through its Security Management Plan, CPKC maintains a comprehensive, risk-based plan that is modelled on and was developed in conjunction with the security plan prepared by the Association of American Railroads post-September 11, 2001. This plan also covers regulatory requirements such as TSA Cyber Security Directives and auditing requirements. Under this plan, the Company routinely examines and prioritizes cyber vulnerabilities and threats while also testing and revising protective measures for its assets and operations, both physical or cyber. Likewise, the Company’s cybersecurity risk management program entails real-time review and monitoring of CPKC’s cyber-risk exposures and implements strategic processes to manage those risks.

The Company's cybersecurity program utilizes the National Institute of Standards and Technology Cybersecurity Framework as its foundation. Accordingly, CPKC’s program includes periodic risk assessments, penetration testing by a third-party, audit participation, employee and contractor training, and the implementation of technologies to assist in mitigating cybersecurity risks and harms. Incident response procedures, including escalation procedures, are designed, implemented, and periodically tested to assist the Company in detecting, responding to, and recovering from a potential cybersecurity incident, and making any timely notification or disclosure that may be required under the circumstances. The Company scopes the third-party penetration tests as real-world attacks against perimeter defenses and internal processes such as social engineering and phishing.

The Company's cybersecurity risk management program also includes ongoing threat research and analysis conducted with the assistance of third parties, including on emerging threat attack vectors, tactics, actors and motivations. The Company also engages in ongoing network monitoring and has implemented a vulnerability management and patching program. Further, CPKC employs structured vetting and ongoing risk management processes to identify and mitigate cyber risks associated with the use of third-party service providers, including specifically in the area of technology.

To date, risks arising from cybersecurity threats have not materially affected the Company, its results of its operations, or its financial condition. However, the Company also recognizes the reality of the ever-evolving cyber risk landscape faced by industries and businesses across the world. Depending on their source and nature, cyber incidents could in the future materially affect CPKC and its operations, and financial condition.

See “Risk Factors” in Part I, Item 1A of this Form 10-K for further information about information and cybersecurity risk.

Governance and Oversight

The Board of Directors oversees the work of all of its committees, including the Risk and Sustainability Committee. The Risk and Sustainability Committee is responsible for overseeing the Company’s strategic and integrated risk practices, including its approach to management and assessment of cybersecurity risks. The Chief Information Officer (CIO) provides annual and periodic updates to the Risk and Sustainability Committee and the Board of Directors on cybersecurity risks and the Company’s implementation of its strategy for mitigating such risks. In addition, the Company’s Chief Information Security Officer (CISO) also briefs the Risk and Sustainability Committee. The Audit and Finance Committee receives updates on information systems and cybersecurity audit and advisory engagements from the Chief Internal Auditor.

The CISO reports directly to the CIO and is responsible for:

•Overseeing and implementing CPKC's cybersecurity strategy;

•Aligning cybersecurity objectives with the overall business objectives;

•Ensuring compliance with regulatory directives related to cybersecurity;

•Promoting a cybersecurity culture through comprehensive awareness and training programs; and

•Managing and coordinating incident response activities.

The Company's cybersecurity risk management program is supervised by the Managing Director of Enterprise Security who reports directly to the CISO. The Chief Information Officer and CISO regularly update senior leadership and the executive committee on cybersecurity risks.

The CISO, CIO, and certain members of their management team who are involved in implementing the Company's cybersecurity program possess expertise in cybersecurity risk management. Our CISO and CIO each have many years of experience in designing and implementing cybersecurity frameworks and working to mitigate cyber threats. Among other qualifications, certain members of the CISO's and CIO's management team also have certifications as a CISSP (Certified Information Systems Security Professional) and CISM (Certified Information Security Manager).

ITEM 3. LEGAL PROCEEDINGS

For further details, refer to Item 8. Financial Statements and Supplementary Data, Note 26 Commitments and contingencies.

SEC regulations require the disclosure of any proceeding under environmental laws to which a government authority is a party unless the registrant reasonably believes it will not result in sanctions over a certain threshold. The Company uses a threshold of U.S. $1 million for the purposes of determining proceedings requiring disclosure.

From time to time, the Company or its subsidiaries may be subject to information requests from U.S. State or Federal environmental regulatory authorities inquiring as to the Company’s compliance or remediation practices in the U.S. In September 2020, the Company received an initial request for information from the EPA inquiring into the Company’s compliance with the mobile source provisions of the Clean Air Act (“CAA”). The Company has been providing information in response to the EPA’s initial and follow-up requests, and the EPA has issued Notices of Violations, which preliminarily identify certain categories of alleged non-compliance with civil provisions of the CAA pertaining to locomotives and locomotive engines. In December 2022, the U.S. Department of Justice (“DOJ”) sent a communication requesting a meeting with the Company to discuss potentially resolving any alleged noncompliance which included an initial draft consent decree from the DOJ. That initial meeting occurred in January 2023 and communications are ongoing. Neither the EPA nor the DOJ has issued a final compendium of alleged violations, demand for corrective or mitigating actions, or articulated a preliminary civil penalty assessment, and it remains too early to provide a fulsome evaluation of the likely outcome with respect to either the nature of any alleged violations or the amount of any potential civil penalty. The Company will continue to fully cooperate and engage in discussions to resolve the matter.

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to enhance a reader’s understanding of the Company’s results of operations and financial condition. The MD&A is provided as a supplement to and should be read in conjunction with the Company’s Consolidated Financial Statements and the related notes in Item 8. Financial Statements and Supplementary Data, and other information in this annual report. Except where otherwise indicated, all financial information reflected herein is expressed in Canadian dollars. The following section generally discusses 2023 and 2022 items and comparisons between 2023 and 2022. Discussions of 2021 items and comparisons between 2022 and 2021 that are not included in this Form 10-K can be found in "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7, of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

For purposes of this report, unless the context indicates otherwise, all references herein to “CPKC”, “the Company”, “we”, “our” and “us” refer to Canadian Pacific Kansas City Limited ("CPKC") and its subsidiaries, which includes Kansas City Southern ("KCS") as a consolidated subsidiary on and from April 14, 2023 (the "Control Date"). Prior to April 14, 2023, the Company's 100% interest in KCS was reported as an equity-method investment.

Executive Summary

2023 Results

•Financial performance– In 2023, the Company reported Diluted earnings per share ("EPS") of $4.21, a 12% increase from $3.77 in 2022, and Core adjusted combined diluted EPS of $3.84, a 2% increase from $3.77 in 2022. The Company reported Operating ratio of 65.0%, a 280 basis point increase from 62.2% in 2022, and Core adjusted combined operating ratio of 62.0%, a 30 basis point increase from 61.7% in 2022. Core adjusted combined diluted EPS and Core adjusted combined operating ratio are defined and reconciled in the Non-GAAP Measures section.

In 2023, equity earnings of KCS prior to the Control Date was $230 million and net income from KCS from the Control Date to December 31, 2023 was $682 million compared to equity earnings of KCS of $1,074 million in 2022. The lower overall contribution from KCS was primarily due to the gain on unwinding of interest rate hedges in 2022 that did not occur in 2023, partially offset by a decrease in net interest expense as a result of the completion of the debt exchange, which is further discussed in the Liquidity and Capital Resources section. In 2023, KCS contributed $963 million to CPKC's Operating income, which increased CPKC's operating ratio by 2.7%.

•Total revenues– The Company’s total revenues increased by 42% to $12,555 million in 2023 from $8,814 million in 2022, primarily due to the impact of the KCS acquisition, increased freight revenues per revenue ton-mile ("RTM'), and higher volumes as measured by RTMs.

Performance Indicators

These key measures are used by management in the planning process to facilitate decisions that continue to drive further productivity improvements in the Company's operations. These key measures reflect how effective the Company’s management is at controlling costs and executing the Company’s operating plan and strategy. Continued monitoring of these key measures enables the Company to take appropriate actions to deliver superior service and grow its business at low incremental cost.

A GTM is defined as the movement of one ton of train weight over one mile. GTMs are calculated by multiplying total train weight by the distance the train moved. Total train weight comprises the weight of the freight cars, their contents, and any inactive locomotives. An increase in GTMs indicates additional workload. The increase in GTMs was primarily due to the impact of the KCS acquisition and higher volumes of Canadian grain, Coal and Automotive. This increase was partially offset by lower volumes of U.S grain, Potash, and crude.

Train miles are defined as the sum of the distance moved by all trains operated on the network. Train miles provide a measure of the productive utilization of our network. A smaller increase in train miles relative to increases in volumes, as measured by RTMs, and/or workload, as measured by GTMs, indicates improved train productivity. The increase in train miles reflects the impact of a 29% increase in workload (GTMs), and an 8% decrease in average train weights, which was primarily due to the impact of the KCS acquisition.

Fuel efficiencyis defined as U.S. gallons of locomotive fuel consumed per 1,000 GTMs. Fuel consumed includes gallons from freight, yard and commuter service but excludes fuel used in capital projects and other non-freight activities. An improvement in fuel efficiency indicates operational cost

CPKC 2023 ANNUAL REPORT / 37

savings. The decrease in fuel efficiency was mainly driven by a decrease in average train weights of 8% primarily due to the impact of the KCS acquisition as a result of the KCS network running lighter trains.

An employee is defined as an individual currently engaged in full-time, part-time, or seasonal employment with the Company. The Company monitors employment and workforce levels in order to efficiently meet service and strategic requirements. The number of employees is a key driver to total compensation and benefits costs. The increase in the average number of total employees was due to the acquisition of KCS and to support anticipated volume growth.

Results of Operations

Operating Revenues

For the year ended December 31 2023 2022 Total Change % Change

Freight revenue per carload (in dollars) $ 3,036 $ 3,101 $ (65) (2)

Freight revenue per revenue ton-mile (in cents) 6.50 5.82 0.68 12

The Company’s revenues are primarily derived from transporting freight. Changes in freight volumes generally contribute to corresponding changes in Freight revenues and certain variable expenses such as fuel, equipment rents, and crew costs. Non-freight revenues are generated from leasing of certain assets, interline switching, and other arrangements, including contracts with passenger service operators, fibre optic agreements, and logistical services.

Total Revenues

The increase in Freight revenues wasprimarily due to the impact of the KCS acquisition of $3,405 million, increased freight revenue per RTM, and higher volumes as measured by RTMs.The increase in Non-freight revenues was primarily due to the impact of the KCS acquisition of $62 million, higher interline switching revenue, higher revenue from a fibre optic agreement, and higher leasing revenue.

RTMs

RTMs are defined as the movement of one revenue-producing ton of freight over a distance of one mile. RTMs measure the relative weight and distance of rail freight moved by the Company. The increase in RTMs was primarily due to the impact of the KCS acquisition and higher volumes of Canadian grain, Coal, and Automotive, partially offset by lower volumes of U.S. grain, Potash, and crude. Carloads have increased more than RTMs due to the impact of the KCS acquisition as KCS has a shorter average length of haul.

Freight Revenue per RTM

Freight revenue per RTM is defined as freight revenue per revenue-producing ton of freight over a distance of one mile. This is an indicator of yield. The increase in freight revenue per RTM was primarily due to higher freight rates and the favourable impact of the change in foreign exchange ("FX") of $165 million, partially offset by the unfavourable impact to fuel surcharge revenue as a result of lower fuel prices of $200 million.

The increase in Coal revenue was primarily due to the impact of the KCS acquisition, higher volumes of Canadian coal to Vancouver and Thunder Bay as a result of prior year production challenges at the mines, higher volumes of U.S. coal, and increased freight revenue per RTM. This increase was partially offset by the unfavourable impact to fuel surcharge revenue as a result of lower fuel prices and lower volumes of Canadian coal to Kamloops, B.C. Freight revenue per RTM increased due to higher freight rates and the favourable impact of the change in FX.

Potash

For the year ended December 31 2023 2022 Total Change % Change

Freight revenues (in millions) $ 566 $ 581 $ (15) (3)

Freight revenue per carload (in dollars) $ 3,687 $ 3,631 $ 56 2

Freight revenue per revenue ton-mile (in cents) 3.35 3.20 0.15 5

The decrease in Potash revenue was primarily due to lower volumes of export potash to Vancouver as a result of the International Longshore and Warehouse Union's strike in July, lower volumes of export potash to the U.S. Pacific Northwest as a result of an equipment failure at the Port of Portland, Oregon, and the unfavourable impact to fuel surcharge revenue as a result of lower fuel prices. This decrease was partially offset by increased freight revenue per RTM and higher volumes of domestic potash. Freight revenue per RTM increased due to higher freight rates and the favourable impact of the change in FX. RTMs decreased more than carloads due to moving lower volumes of export potash to Vancouver, which has a longer length of haul.

The increase in Metals, minerals and consumer products revenue was primarily due to the impact of the KCS acquisition, increased freight revenue per RTM, and higher volumes of aggregates, minerals and metals, and consumer products. This increase was partially offset by the unfavourable impact to fuel surcharge revenue as a result of lower fuel prices and lower volumes of steel. Freight revenue per RTM increased due to higher freight rates and the favourable impact of the change in FX.

Automotive

For the year ended December 31 2023 2022 Total Change % Change

Freight revenue per revenue ton-mile (in cents) 26.10 25.23 0.87 3

The increase in Automotive revenue was primarily due to the impact of the KCS acquisition, higher volumes from Chicago, various origins in Ontario, Vancouver, and Kansas City, Missouri to various destinations in Canada, partially due to prior year global supply chain challenges, and increased freight revenue per RTM. This increase was partially offset by the unfavourable impact to fuel surcharge revenue as a result of lower fuel prices. Freight revenue per RTM increased due to higher freight rates and the favourable impact of the change in FX. RTMs increased more than carloads due to moving higher volumes from Chicago, Ontario, and Kansas City to western Canada and higher volumes from Vancouver to eastern Canada, which have longer lengths of haul.

Intermodal

For the year ended December 31 2023 2022 Total Change % Change

Freight revenue per carload (in dollars) $ 1,534 $ 1,892 $ (358) (19)

Freight revenue per revenue ton-mile (in cents) 7.36 7.19 0.17 2

The increase in Intermodal revenue was primarily due to the impact of the KCS acquisition, higher freight rates, higher international intermodal volumes due to onboarding a new customer and higher volumes imported through the Port of Vancouver, higher domestic wholesale volumes, and the favourable impact of the change in FX. This increase was partially offset by lower intermodal ancillary revenue, lower domestic intermodal volumes due to lower cross-border volumes between Canada and the U.S. and lower retail volumes, lower international intermodal volumes to and from the Port of Saint John, New Brunswick and to and from the Port of Montréal, Québec, and the unfavourable impact to fuel surcharge revenue as a result of lower fuel prices.

CPKC 2023 ANNUAL REPORT / 41

Operating Expenses

Compensation and Benefits

Compensation and benefits expense includes employee wages, salaries, fringe benefits, and stock-based compensation. The increase in Compensation and benefits expense was primarily due to:

•the impact of the KCS acquisition of $645 million, including acquisition-related costs incurred by KCS of $55 million, which were primarily comprised of restructuring charges of $50 million;

•the impact of wage and benefit inflation;

•higher incentive compensation;

•reduced labour efficiencies, including the impact of reduced train weights;

•the unfavourable impact of the change in FX of $16 million;

•higher acquisition-related costs incurred by CPKC, excluding KCS's acquisition-related costs, of $14 million, including stock-based compensation of $10 million; and

•increased volume variable expenses as a result of an increase in workload as measured by GTMs.

This increase was partially offset by a reduction of $77 million in defined benefit pension current service costs and the favourable impact of changes in common share price of $12 million on stock-based compensation.

Fuel

Fuel expense consists mainly of fuel used by locomotives and includes provincial, state, and federal fuel taxes. The increase in Fuel expense was primarily due to:

•the impact of the KCS acquisition of $441 million;

•the unfavourable impact of the change in FX of $42 million; and

•an increase in workload, as measured by GTMs.

This increase was partially offset by the favourable impact of lower fuel prices of $221 million.

Materials

Materials expense includes the cost of material used for maintenance of track, locomotives, freight cars, and buildings, as well as software sustainment. The increase in Materials expense was primarily due to the impact of the KCS acquisition of $89 million and the unfavourable impact of inflation, partially offset by a decrease in locomotive maintenance.

Equipment Rents

Equipment rents expense includes the cost associated with using other railways' freight cars, intermodal equipment, and locomotives, net of recoveries received from other railways for the use of the Company’s equipment. The increase in Equipment rents expense was primarily due to:

•the impact of the KCS acquisition of $110 million;

•greater usage of pooled freight cars;

•reduced rental income received from other railways; and

•slower cycle times.

This increase was partially offset by greater recoveries from other railway's use of the company's locomotives.

42 / CPKC 2023 ANNUAL REPORT

Depreciation and Amortization

Depreciation and amortization expense is the charge associated with the use of track and roadway, rolling stock, buildings, and other depreciable assets, including assets related to the Company's concession with the Mexican government, as well as amortization of finite life intangible assets. The increase in Depreciation and amortization expense was primarily due to:

•the impact of the KCS acquisition of $629 million, including additional depreciation of $175 million and amortization of $59 million attributed to fair value adjustments to properties and intangible assets with finite lives recognized upon the acquisition of KCS;

•a higher depreciable asset base as a result of capital program spending in 2023 and recent years; and

•the unfavourable impact of the change in FX of $8 million.

Purchased Services and Other

Land sales (gains) losses (3) (24) 21 (88)

(1) 2023 includes KCS results from April 14 to December 31, 2023.

Purchased services and other expense encompasses a wide range of third-party costs, including expenses for joint facilities, personal injury and damage claims, environmental remediation, property taxes, contractor and consulting fees, and insurance. The increase in Purchased services and other expense was primarily due to:

•the impact of the KCS acquisition of $590 million, including acquisition-related costs incurred by KCS of $18 million, reported in Other;

•an increased number of casualty incidents and higher personal injury costs, reported in Casualty;

•cost inflation;

•lower gains on land sales;

•higher acquisition-related costs incurred by CPKC, excluding KCS's acquisition-related costs, of $19 million including payments made to certain communities across the combined network to address the environmental and societal impacts of increased traffic, reported in Other; and

•the unfavourable impact of the change in FX of $18 million.

This increase was partially offset by a business interruption insurance recovery of $51 million, reported in Other.

Other Income Statement Items

Equity Earnings of Kansas City Southern

On April 14, 2023, the Company assumed control of KCS and subsequently ceased recognizing equity earnings of KCS.

For the period from January 1 to April 13, 2023, the Company recognized $230 million (U.S. $170 million) of equity earnings of KCS, a decrease of $844 million or 79%, from $1,074 million (U.S. $820 million) in the year ended December 31, 2022. This amount is net of amortization of basis differences of $48 million (U.S. $35 million) associated with KCS purchase accounting, a decrease of $115 million or 71%, from $163 million (U.S. $125 million) in the year ended December 31, 2022, and is net of acquisition-related costs (net of tax) incurred by KCS. These basis differences relate to depreciable property, plant and equipment, intangible assets with definite lives, and long-term debt, and are amortized over the related assets' remaining useful lives, and the remaining terms to maturity of the debt instruments. Acquisition-related costs (net of tax) incurred by KCS in the period from January 1 to April 13, 2023 were $11 million (U.S. $8 million), a decrease of $38 million or 78%, from $49 million (U.S. $38 million) in the year ended December 31, 2022. These decreases are attributable to the derecognition of KCS as an equity investment following the acquisition of control by CPKC on April 14, 2023. Equity earnings of KCS recognized in 2022 also included KCS's gain on unwinding of interest rate hedges of $212 million, which is net of the associated purchase accounting basis difference and tax. KCS U.S. dollar historical results were translated at the average FX rate for the period from January 1 to April 13, 2023 and the year ended December 31, 2022 of $1.00 USD = $1.35 CAD and $1.00 USD = $1.30 CAD, respectively.

CPKC 2023 ANNUAL REPORT / 43

Other Expense

Other expense consists of gains and losses from the change in FX on cash and working capital, the impact of foreign currency forwards, financing costs, shareholder costs, equity earnings, and other non-operating expenditures. Other expense was $52 million in 2023, an increase of $35 million, or 206%, from $17 million in 2022. The increase was primarily due to the impact of the KCS acquisition, including foreign exchange losses on forward contracts to sell Mexican pesos and buy U.S.dollars, of $27 million, and net acquisition-related costs of $6 million driven by the KCS debt exchange. Additional information concerning the KCS debt exchange is included in Item 8. Financial Statements and Supplementary Data, Note 17 Debt.

Other Components of Net Periodic Benefit Recovery

Other components of net periodic benefit recovery are related to the Company's pension and other post-retirement and post-employment benefit plans. It includes interest cost on benefit obligation, expected return on plan assets, recognized net actuarial loss, and amortization of prior service costs. Other components of net periodic benefit recovery were $327 million in 2023, a decrease of $84 million, or 20%, from $411 million in 2022. This decrease was primarily due to an increase in interest cost on the benefit obligation of $109 million and a decrease in the expected return on plan assets of $77 million, partially offset by a decrease in recognized net actuarial losses of $103 million.

Net Interest Expense

Net interest expense includes interest on long-term debt and finance leases. Net interest expense was $771 million in 2023, an increase of $119 million, or 18%, from $652 million in 2022. This increase was primarily due to:

•interest of $106 million incurred on debt issued under the KCS debt exchange;

•the unfavourable impact of the change in FX of $20 million;

•higher interest on commercial paper of $19 million as a result of higher interest rates and higher borrowings; and

•the impact of the KCS Purchase Accounting of $13 million.

This increase was partially offset by lower interest costs of $19 million following the repayment of maturing long-term debt and higher interest income of $12 million.

Remeasurement of Kansas City Southern

On April 14, 2023, the Company assumed control of KCS and accounted for its acquisition as a business combination achieved in stages. The Company's investment in KCS was accounted for using the equity method of accounting prior to assuming control. On control, the carrying value of the previously held equity investment in KCS was remeasured to its fair value and upon derecognition, a loss of $7,175 million was recognized in the Company's Consolidated Statements of Income for the year ended December 31, 2023. This loss was primarily due to the reversal of a value equal to the deferred tax liability on the outside basis difference which was initially recognized with the investment in KCS.

Income Tax (Recovery) Expense

Income tax recovery was $6,976 million in 2023, a change of $7,604 million, or 1,211%, from an income tax expense of $628 million in 2022. This change was primarily due to:

•a deferred tax recovery of $7,832 million on the derecognition of the deferred tax liability on the outside basis difference of the investment in KCS upon acquiring control;

•a deferred tax recovery of $58 million on the revaluation of deferred income tax balances on unitary state apportionment changes;

•higher current tax recoveries on acquisition-related costs of $14 million associated with the KCS acquisition incurred by legacy CP; and

•lower current tax expense due to lower taxable earnings.

This change was partially offset by the impact of the KCS acquisition of $256 million, including current tax expense related to tax settlements of $16 million with the Servicio de Administración Tributaria ("SAT”) (Mexican tax authority) in relation to taxation years for which audits have closed and the estimated impact of potential future audit settlements, deferred tax recoveries on the amortization relating to purchase accounting fair value adjustments of $67 million, and current tax recoveries on acquisition-related costs of $7 million. In addition to the impact of the KCS acquisition, there was also an increase in income tax expense due to a higher effective tax rate and a reversal of an uncertain tax position in 2022 related to a prior period of $24 million. As a result of the KCS debt exchange an offsetting current tax expense and deferred tax recovery of $101 million is included in "income tax (recovery) expense".

The effective income tax rate for 2023 was 228.50% and 24.01% on a Core adjusted basis. The effective income tax rate for 2022 was 15.16% and 22.24% on a Core adjusted basis. The Company's 2024 Core adjusted effective tax rate is expected to be between 25.00% to 25.50%. The Core adjusted effective tax rate is a Non-GAAP measure, calculated as the effective tax rate adjusted for significant items as they are not considered indicative of future financial trends either by nature or amount nor provide comparability to past performance. The Company uses Core adjusted effective tax rate to evaluate CPKC’s operating performance and for planning and forecasting future profitability. Core adjusted effective tax rate also excludes equity earnings of KCS (net of tax) and KCS purchase accounting to provide financial statement users with additional transparency by isolating the impact of KCS purchase accounting. This Non-GAAP measure does not have a standardized meaning and is not defined by GAAP and, therefore, may not be comparable

44 / CPKC 2023 ANNUAL REPORT

to similar measures presented by other companies. Significant items and KCS purchase accounting are discussed further in Non-GAAP Measures of this Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. The Company’s 2024 outlook for its Core adjusted annualized effective income tax rate is based on certain assumptions about events and developments that may or may not materialize, or that may be offset entirely or partially by new events and developments. These assumptions are discussed further in Item 1A. Risk Factors.

Impact of Foreign Exchange on Earnings and Foreign Exchange Risk

Although the Company is headquartered in Canada and reports in Canadian dollars, a significant portion of its revenues, expenses, assets and liabilities including debt are denominated in U.S. dollars and Mexican pesos. In addition, equity earnings or losses of KCS are denominated in U.S. dollars. The value of the Canadian dollar is affected by a number of domestic and international factors, including, without limitation, economic performance, commodity prices, and Canadian, U.S., and international monetary policies. Fluctuations in FX affect the Company’s results because revenues and expenses denominated in U.S. dollars and Mexican pesos are translated into Canadian dollars. U.S. dollar-denominated revenues and expenses increase (decrease) when the Canadian dollar weakens (strengthens) in relation to the U.S. dollar. Mexican peso-denominated revenues and expenses increase (decrease) when the U.S. dollar weakens (strengthens) in relation to the Mexican peso.

In 2023, the U.S. dollar has strengthened to an average rate of $1.35 Canadian/U.S. dollar, compared to $1.30 Canadian/U.S. dollar in 2022, resulting in an increase in Total revenues of $166 million, an increase in Total operating expenses of $90 million, and an increase in Net interest expense of $20 million.

In 2024, the Company expects that every $0.01 weakening (or strengthening) of the Canadian dollar relative to the U.S. dollar, positively (or negatively) impacts Total revenues by approximately $75 million (2023 – approximately $37 million excluding the impact of KCS), negatively (or positively) impacts Operating expenses by approximately $46 million (2023 – approximately $18 million excluding the impact of KCS), and negatively (or positively) impacts Net interest expense by approximately $5 million (2023 – approximately $4 million excluding the impact of KCS) on an annualized basis.

In 2024, the Company expects that every Ps.0.10 strengthening (or weakening) of the Mexican peso relative to the Canadian dollar, positively (or negatively) impacts Total revenues by approximately $7 million and negatively (or positively) impacts Operating expenses by approximately $7 million on an annualized basis.

The Company uses U.S. dollar-denominated debt and operating lease liabilities to hedge its net investment in U.S. operations. As at December 31, 2023, the net investment in U.S. operations is greater than the total U.S. denominated debt and the operating lease liabilities. Consequently, FX translation on the Company's unhedged net investment in U.S. operations is recognized in Other comprehensive income. There is no additional impact on earnings in Other expense related to the FX translation on the Company’s debt and operating lease liabilities.

To manage its exposure to fluctuations in exchange rates between Canadian dollars, U.S. dollars, and Mexican pesos, the Company may sell or purchase U.S. dollar or Mexican peso forwards at fixed rates in future periods. In addition, changes in the exchange rate between the Canadian dollar and other currencies (including the U.S. dollar and Mexican peso) make the goods transported by the Company more or less competitive in the world marketplace and may in turn positively or negatively affect revenues.

Impact of Fuel Price on Earnings

Fluctuations in fuel prices affect the Company’s results because fuel expense constitutes a significant portion of the Company's operating costs. As fuel prices fluctuate, there will be a timing impact on earnings, as discussed further in Item 1. Business, Operations, Fuel Cost Adjustment Program and Item 1A. Risk Factors, “The Company is affected by fluctuating fuel prices”.

The impact of fuel price on earnings includes the impacts of carbon taxes, levies, and obligations under cap-and-trade programs recovered and paid, on revenue and expenses, respectively.

In 2023, the favourable impact of fuel prices on Operating income was $21 million. Lower fuel prices resulted in a decrease in Total operating expenses of $221 million from 2022. Lower fuel prices, partially offset by the favourable impact of timing of recoveries under the Company's fuel cost adjustment program, resulted in a decrease in Total revenues of $200 million from 2022.

Impact of Share Price on Earnings and Stock-Based Compensation

Fluctuations in the Common Share price affect the Company's operating expenses because share-based liabilities are measured at fair value. The Company's Common Shares are listed on the Toronto Stock Exchange ("TSX") and the New York Stock Exchange ("NYSE") with ticker symbol "CP".

In 2023, the impact of the change in Common Share price resulted in stock-based compensation expense of $4 million, a decrease of $12 million, from $16 million in 2022.

CPKC 2023 ANNUAL REPORT / 45

Based on information available at December 31, 2023 and expectations for 2024 share-based grants, for every $1.00 change in Common Share price, stock-based compensation expense has a corresponding change of approximately $1.6 million to $2.3 million (2022 – approximately $1.2 million to $1.8 million). This excludes the impact of changes in Common Share price relative to the S&P/TSX 60 Index, S&P 500 Industrials Index, and to Class I railways, which may trigger different performance share unit payouts. Stock-based compensation may also be impacted by non-market performance conditions.

Additional information concerning stock-based compensation is included in Item 8. Financial Statements and Supplementary Data, Note 24 Stock-based compensation.

Liquidity and Capital Resources

The Company's primary sources of liquidity include its Cash and cash equivalents, commercial paper program, bilateral letter of credit facilities, and revolving credit facility. The Company believes that these sources as well as cash flow generated through operations and existing debt capacity are adequate to meet its short-term and long-term cash requirements. The Company is not aware of any material trends, events, or uncertainties that would create any deficiencies in the Company's liquidity.

As at December 31, 2023, the Company had $464 million of Cash and cash equivalents compared to $451 million at December 31, 2022.

Effective May 11, 2023, the Company entered into a second amended and restated credit agreement to extend the maturity dates and increase the total amount available under the revolving credit facility. The amendment increased the amount available of the five-year tranche from U.S. $1.0 billion to U.S.$1.1 billion and extended the maturity date from September 27, 2026 to May 11, 2028. The amendment also increased the amount available of the two-year tranche from U.S. $300 million to U.S. $1.1 billion and extended the maturity date from September 27, 2023 to May 11, 2025. The Company also terminated the legacy KCS credit facility effective May 11, 2023. As at December 31, 2023 the Company's existing revolving credit facility was undrawn. The revolving credit facility agreement requires the Company to maintain a financial covenant. As at December 31, 2023, the Company was in compliance with all terms and conditions of the credit facility arrangements and satisfied the financial covenant.

Effective March 14, 2022, the Company extended the maturity date of the U.S. $500 million term facility to September 15, 2022. During the year ended December 31, 2022, the Company repaid in full the outstanding borrowings of U.S. $500 million ($636 million) on the term facility. The facility was automatically terminated on September 15, 2022 following the final principal repayment.

The Company has a commercial paper program that enables it to issue commercial paper in the form of unsecured promissory notes. On July 12, 2023, the Company increased the maximum aggregate principal amount of commercial paper available to be issued from U.S. $1.0 billion to U.S $1.5 billion. The Company also terminated the legacy KCS commercial paper program effective May 19, 2023. The Company's existing commercial paper program is backed by the revolving credit facility. As at December 31, 2023, the Company had total commercial paper borrowings outstanding of U.S. $800 million (December 31, 2022 – U.S. $nil).

As at December 31, 2023, under its bilateral letter of credit facilities, the Company had letters of credit drawn of $93 million from a total available amount of $300 million (December 31, 2022 - $75 million). Under the bilateral letter of credit facilities, the Company has the option to post collateral in the form of Cash or cash equivalents, equal at least to the face value of the letter of credit issued. These agreements permit the Company to withdraw amounts posted as collateral at any time; therefore, the amounts posted as collateral are presented as "Cash and cash equivalents" on the Company's Consolidated Balance Sheets.As at December 31, 2023, the Company did not have any collateral posted on its bilateral letter of credit facilities (December 31, 2022 – $nil).

Contractual Commitments

The Company’s material cash requirements from known contractual obligations and commitments to make future payments primarily consist of long-term debt and related interest, supplier purchases, capital commitments, leases, and other long term liabilities. Outstanding obligations related to debt and leases can be found in Item 8. Financial Statements and Supplementary Data, Note 17 Debt and Note 20 Leases. Interest obligations related to debt and finance leases amount to $773 million within the next 12 months, with the remaining amount committed thereafter of $16,513 million.

Supplier purchase agreements and other long-term liabilities amount to $235 million and $71 million within the next 12 months, respectively, with the remaining amount committed thereafter of $309 million and $618 million, respectively. Other long-term liabilities include expected cash payments for environmental remediation, post-retirement benefits, worker’s compensation benefits, long-term disability benefits, pension benefit payments for the Company’s non-registered supplemental pension plan, and certain other long-term liabilities. Pension payments are discussed further in Critical Accounting Estimates of this Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. Capital commitments are discussed further in in Item 8. Financial Statements and Supplementary Data, Note 26 Commitments and Contingencies.

46 / CPKC 2023 ANNUAL REPORT

Concession Duty

Under CPKCM's 50-year Concession, which will expire in 2047 unless extended, CPKCM pays annual concession duty expense of 1.25% of its gross revenues. Capital commitments under the CPKCM concession can be found in Item 8. Financial Statements and Supplementary Data, Note 26 Commitments and contingencies.

Guarantees

Refer to Item 8. Financial Statements and Supplementary Data, Note 27 Guarantees for details.

Operating Activities

Cash provided by operating activities was $4,137 million in 2023, a decrease of $5 million compared to $4,142 million in 2022. The decrease was primarily due to an unfavourable change in working capital driven by an increase in freight and non-freight accounts receivable along with higher tax installments paid in 2023, and the settlement of Mexican tax audits in the third and fourth quarters of 2023 compared to the same period of 2022.

This decrease was partially offset by higher cash generating income, including the impact of the acquisition of KCS.

Investing Activities

Cash used in investing activities was $2,162 million in 2023, an increase of $666 million, or 45%, from $1,496 million in 2022. This increase was primarily due to higher additions to properties, including the impact of the acquisition of KCS. This increase was partially offset by cash acquired on control of KCS.

Capital Programs

Additions to capital

Total – accrued additions to capital 2,491 1,565

Less:

Non-cash transactions 23 8

Track installation capital programs

Track miles of rail laid (miles) 323 271

Track miles of rail capacity expansion (miles) 24 17

Crossties installed (thousands) 1,617 1,215

Track and roadway expenditures include the replacement and enhancement of the Company’s track infrastructure. Of the $1,623 million additions in 2023 (2022 – $1,048 million), approximately $1,373 million (2022 – $967 million) was invested in the renewal of depleted assets, namely rail, ties, ballast, signals, and bridges. Approximately $250 million (2022 – $81 million) was invested in network improvements and growth initiatives.

Rolling stock investments encompass locomotives and railcars. In 2023, expenditures on locomotives were approximately $186 million (2022 – $84 million) and were focused on the continued re-investment in the Company's existing locomotive fleet. Railcar investment of approximately $87 million (2022 – $159 million) in 2023 was largely focused on the renewal of depleted assets, including the acquisition of new freight cars.

In 2023, investments in buildings were approximately $112 million (2022 - $75 million) and included the new operations building in Kansas City, facility upgrades, renovations, and shop equipment. Other investments were $483 million (2022 – $199 million) and included investments in intermodal equipment, information systems, work equipment and vehicles.

CPKC 2023 ANNUAL REPORT / 47

Cash invested in additions to properties by KCS was $221 million for the period from January 1 to April 13, 2023 (U.S. $164 million at average exchange rate of $1.00 USD = $1.35 CAD). Expenditures mainly relate to renewal and replacement of track infrastructure and re-investment in existing locomotive fleet.

For 2024, the Company expects to invest approximately $2.75 billion in its capital programs. Capital programs will be financed with cash generated from operations. Approximately 60% to 70% of the planned capital programs is for track and roadway. Approximately 10% to 15% is expected to be allocated to rolling stock, including railcars and locomotive improvements. Approximately 5% to 10% is expected to be allocated to information services, and 5% is expected to be allocated to buildings. Other investments are expected to be approximately 10%. Additional discussion of capital commitments can be found in Item 8. Financial Statements and Supplementary Data, Note 26 Commitments and Contingencies.

Financing Activities

The Company continues to focus on debt repayments in order to return to its long term leverage ratio following the acquisition of KCS. Cash used in financing activities was $1,955 million in 2023, a decrease of $342 million, or 15%, from cash used in financing activities of $2,297 million in 2022. The decrease was primarily due to an increase of $1,095 million in net issuances of commercial paper compared to $415 million of repayments in 2022, and principal repayments of $636 million (U.S. $500 million) on a term loan in 2022.

This decrease was partially offset primarily by principal repayments of $1,000 million 1.589% 2-year Notes, $479 million (U.S. $350 million) of 4.45% 12.5-year Notes, $272 million (U.S. $199 million) of 3.85% 10-year Senior Notes, and $592 million (U.S. $439 million) of 3.00% 10-year Senior Notes, compared to principal repayments of $125 million 5.10% 10-year Medium Term Notes, $313 million (U.S. $250 million) of 4.50% 10-year Notes, and $97 million (U.S. $76 million) of the 6.99% Finance lease in 2022.

Credit Measures

Credit ratings provide information relating to the Company’s operations and liquidity, and affect the Company’s ability to obtain short-term and long-term financing and/or the cost of such financing. The applicable margin that applies to outstanding loans under the Company’s revolving credit facility is based on the credit rating assigned to the Company’s senior unsecured and unsubordinated debt.

If the Company’s credit ratings were to decline to below investment-grade levels, the Company could experience a significant increase in its interest cost for new debt along with a negative effect on its ability to readily issue new debt.

Credit ratings and outlooks are based on the rating agencies’ methodologies and can change from time to time to reflect their views of the Company. Their views are affected by numerous factors including, but not limited to, the Company’s financial position and liquidity along with external factors beyond the Company’s control.

As at December 31, 2023, the Company's credit ratings from Standard & Poor's Rating Services ("Standard & Poor's") and Moody's Investor Service ("Moody's") remain unchanged from December 31, 2022. The following table shows the ratings issued for the Company by the rating agencies noted as of December 31, 2023 and is being presented as it relates to the Company’s cost of funds and liquidity.

As of the date of the filing of the Form 10-K, CPRC had U.S. $14,714 million principal amount of debt securities outstanding due through 2115 which includes the debt exchanged for KCS debt as described below, and U.S. $30 million and GBP £3 million in perpetual 4% consolidated debenture stock, for all of which CPKC is the guarantor subject to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act"), as amended. As of the same date, CPRC also had $2,300 million principal amount of debt securities issued under Canadian Securities Law due through 2050 for which CPKC is the guarantor and not subject to the Exchange Act.

CPKC fully and unconditionally guarantees the payment of the principal (and premium, if any) and interest on the debt securities and consolidated debenture stock issued by CPRC, any sinking fund or analogous payments payable with respect to such securities, and any additional amounts payable when they become due, whether at maturity or otherwise. The guarantee is CPKC’s unsubordinated and unsecured obligation and ranks equally with all of CPKC’s other unsecured, unsubordinated obligations.

CPKC will be released and relieved of its obligations under the guarantees after obligations to the holders are satisfied in accordance with the terms of the respective instruments.

On March 20, 2023, CPKC and CPRC announced offers to exchange any and all validly tendered (and not validly withdrawn) and accepted notes of seven series, previously issued by KCS (the “Old Notes") for notes to be issued by CPRC (the "CPRC Notes"). As of April 19, 2023, U.S. $3,014 million of Old Notes of such seven series were tendered and accepted in exchange for U.S. $3,014 million of CPRC Notes in seven corresponding series.

Each series of CPRC Notes has the same interest rates, interest payment dates, maturity dates, and substantively the same optional redemption provisions as the corresponding series of Old Notes.

In exchange for each U.S. $1,000 principal amount of Old Notes that was validly tendered prior to March 31, 2023 (the "Early Participation Date"), holders of Old Notes received consideration consisting of U.S. $1,000 principal amount of CPRC Notes and a cash amount of U.S. $1.00. The total consideration included an early participation premium, consisting of U.S. $30 principal amount of CPRC Notes per U.S. $1,000 principal amount of Old Notes. In exchange for each U.S. $1,000 principal amount of Old Notes that was validly tendered after the Early Participation Date but prior to the expiration of the exchange offers on April 17, 2023 (the "Expiration Date") and not validly withdrawn, holders of Old Notes received consideration consisting of U.S. $970 principal amount of CPRC Notes and a cash amount of U.S. $1.00.

CPKC has fully and unconditionally guaranteed the payment of the principal (and premium, if any) and interest, on the CPRC Notes, and any additional amounts payable with respect to the CPRC Notes, when they become due and payable, whether at the stated maturity thereof or by declaration of acceleration, call for redemption, or otherwise. The CPRC Notes and the related guarantees are part of CPRC’s and CPKC’s respective unsecured obligations and rank equally with all of CPRC’s and CPKC’s existing and future unsecured and unsubordinated indebtedness.

Non-GAAP Measures

The Company presents Non-GAAP measures, including Core adjusted combined operating ratio and Core adjusted combined diluted earnings per share, to provide an additional basis for evaluating underlying earnings trends in the Company's current periods' financial results that can be compared with the results of operations in prior periods. Management believes these Non-GAAP measures facilitate a multi-period assessment of long-term profitability.

These Non-GAAP measures have no standardized meaning and are not defined by accounting principles generally accepted in the United States of America ("GAAP") and, therefore, may not be comparable to similar measures presented by other companies. The presentation of these Non-GAAP measures is not intended to be considered in isolation from, as a substitute for, or as superior to the financial information presented in accordance with GAAP.

Non-GAAP Performance Measures

On April 14, 2023, CP obtained control of KCS and CPKC began consolidating KCS, which had been accounted for under the equity method of accounting between December 14, 2021 and April 13, 2023. On the Control Date, CPKC’s previously-held interest in KCS was remeasured to its Control Date fair value. CPKC presents Core adjusted combined operating ratio and Core adjusted combined diluted earnings per share to give effect to results after isolating and removing the impact of the acquisition of KCS on those results. These measures provide a comparison to prior period financial information, as adjusted to exclude certain significant items, and are used to evaluate CPKC’s operating performance and for planning and forecasting future business operations and future profitability.

Management believes the use of Non-GAAP measures provides meaningful supplemental information about our operating results because they exclude certain significant items that are not considered indicative of future financial trends either by nature or amount or provide improved comparability to past performance. As a result, these items are excluded for management's assessment of operational performance, allocation of resources, and preparation of annual budgets. These significant items may include, but are not limited to, restructuring and asset impairment charges, individually significant gains and losses from sales of assets, acquisition-related costs, the merger termination payment received, KCS's gain on unwinding of interest rate hedges (net of CPKC's associated purchase accounting basis differences and tax), as recognized within "Equity (earnings) loss of Kansas City Southern" in the Company's Consolidated Statements of Income, loss on derecognition of CPKC’s previously held equity method investment in KCS, discrete tax items, changes in the outside basis tax difference between the carrying amount of CPKC's equity investment in KCS and its tax basis of this investment, a deferred tax recovery related to the elimination of the deferred tax liability on the outside basis difference of the investment, settlement of Mexican taxes relating to prior years, changes in income tax rates, changes to an uncertain tax item, and certain items outside the control of management. Acquisition-

CPKC 2023 ANNUAL REPORT / 51

related costs include legal, consulting, financing fees, integration costs including third-party services and system migration, debt exchange transaction costs, community investments, fair value gain or loss on FX forward contracts and interest rate hedges, FX gain on U.S. dollar-denominated cash on hand from the issuances of long-term debt to fund the KCS acquisition, restructuring, employee retention and synergy incentive costs, and transaction and integration costs incurred by KCS. These items may not be non-recurring, and may include items that are settled in cash. Specifically, due to the magnitude of the acquisition, its significant impact to the Company’s business and complexity of integrating the acquired business and operations, the Company expects to incur acquisition-related costs beyond the year of acquisition. Management believes excluding these significant items from GAAP results provides an additional viewpoint which may give users a consistent understanding of CPKC's financial performance when performing a multi-period assessment including assessing the likelihood of future results. Accordingly, these Non-GAAP financial measures may provide additional insight to investors and other external users of CPKC's financial information.

In addition, Core adjusted combined operating ratio and Core adjusted combined diluted earnings per share exclude KCS purchase accounting. KCS purchase accounting represents the amortization of basis differences being the incremental depreciation and amortization in relation to fair value adjustments to properties and intangible assets, incremental amortization in relation to fair value adjustments to KCS’s investments, amortization of the change in fair value of debt of KCS assumed on the Control Date, and depreciation and amortization of fair value adjustments that are attributable to non-controlling interest, as recognized within "Depreciation and amortization", "Other expense", "Net interest expense", and "Net loss attributable to non-controlling interest", respectively, in the Company's Consolidated Statements of Income. During the periods that KCS was equity accounted for, from December 14, 2021 to April 13, 2023, KCS purchase accounting represents the amortization of basis differences, being the difference in value between the consideration paid to acquire KCS and the underlying carrying value of the net assets of KCS immediately prior to its acquisition by the Company, net of tax, as recognized within "Equity (earnings) loss of Kansas City Southern" in the Company's Consolidated Statements of Income. All assets subject to KCS purchase accounting contribute to income generation and will continue to amortize over their estimated useful lives. Excluding KCS purchase accounting from GAAP results provides financial statement users with additional transparency by isolating the impact of KCS purchase accounting.

Reconciliation of GAAP Performance Measures to Non-GAAP Performance Measures

The following tables reconcile the most directly comparable measures presented in accordance with GAAP to the Non-GAAP measures:

Core Adjusted Combined Diluted Earnings per Share

Core adjusted combined diluted earnings per share is calculated using Net income attributable to controlling shareholders reported on a GAAP basis adjusted for significant items less KCS purchase accounting, divided by the weighted-average diluted number of Common Shares outstanding during the period as determined in accordance with GAAP. Between December 14, 2021 and April 13, 2023, KCS was accounted for in CPKC's diluted earnings per share reported on a GAAP basis using the equity method of accounting and on a consolidated basis beginning April 14, 2023. As the equity method of accounting and consolidation both provide the same diluted earnings per share for CPKC, no adjustment is required to pre-control diluted earnings per share to be comparable on a consolidated basis.

In 2023, there were five significant items included in the Net income attributable to controlling shareholders as reported on a GAAP basis as follows:

•during the course of the year, a total current tax expense of $16 million related to a tax settlement with the SAT of $13 million and a reserve for the estimated impact of potential future audit settlements of $3 million, that unfavourably impacted Diluted EPS by 2 cents as follows:

–in the fourth quarter, a current tax expense of $1 million related to a tax settlement with the SAT that had minimal impact on Diluted EPS; and

–in the third quarter, a total current tax expense of $15 million related to a tax settlement with the SAT of $9 million and reserves for the estimated impact of potential future audit settlements of $6 million of which $3 million was settled in the fourth quarter, that unfavourably impacted Diluted EPS by 2 cents;

•in the second quarter, a remeasurement loss of KCS of $7,175 million recognized in "Remeasurement loss of Kansas City Southern" due to the derecognition of CPKC’s previously held equity method investment in KCS and remeasurement at its Control Date fair value that unfavourably impacted Diluted EPS by $7.68;

•during the course of the year, a deferred tax recovery of $72 million on account of changes in tax rates and apportionment that favourably impacted Diluted EPS by 7 cents as follows:

–in the fourth quarter, a deferred tax recovery of $7 million due to CPKC unitary state apportionment changes that favourably impacted Diluted EPS by 1 cent;

–in the third quarter, a deferred tax recovery of $14 million due to decreases in the Iowa and Arkansas state tax rates that favourably impacted Diluted EPS by 2 cents; and

–in the second quarter, a deferred tax recovery of $51 million due to CPKC unitary state apportionment changes that favourably impacted Diluted EPS by 5 cents;

•during the course of the year, a deferred tax recovery of $7,855 million on changes in the outside basis difference on the equity investment in KCS that favourably impacted Diluted EPS by $8.42 as follows:

–in the second quarter, a deferred tax recovery of $7,832 million related to the elimination of the deferred tax liability on the outside basis difference of the investment in KCS that favourably impacted Diluted EPS by $8.39; and

Core adjusted combined diluted earnings per share(2) $ 3.84 $ 3.77

(1)The tax effect of adjustments was calculated as the pre-tax effect of the significant items and KCS purchase accounting listed above multiplied by the applicable tax rate for the above items of 1.37% for the year ended December 31, 2023 and 20.08% for the year ended December 31, 2022. The applicable tax rates reflect the taxable jurisdictions and nature, being on account of capital or income, of the adjustments.

(2) The Company previously used the non-GAAP measure Core adjusted diluted earnings per share, which was calculated as diluted earnings per share adjusted for significant items less KCS purchase accounting. Core adjusted diluted earnings per share was $3.77 for the year ended December 31, 2022, which is the same as the revised measure Core adjusted combined diluted earnings per share, as KCS was equity accounted for within CPKC's results.

Core Adjusted Combined Operating Ratio

Core adjusted combined operating ratio is calculated from reported GAAP revenue and operating expenses adjusted for (1) KCS operating income prior to the Control Date and giving effect to transaction accounting adjustments in a consistent manner with Regulation S-X Article 11 ("Article 11"), where applicable, (2) significant items (acquisition-related costs) that are reported within Operating income, and (3) KCS purchase accounting recognized in Depreciation and amortization and Purchased services and other.

This combined measure does not purport to represent what the actual consolidated results of operations would have been had the Company obtained control of KCS and consolidation actually occurred on January 1, 2022, nor is it indicative of future results. This information is based upon assumptions

(3) The Company previously used the Non-GAAP measure Adjusted operating ratio, which was defined as operating ratio excluding those significant items that are reported within Operating income. Adjusted operating ratio was 61.4% for the year ended December 31, 2022, which was changed to the revised measure Core adjusted combined operating ratio. This change was due to the addition of KCS historical operating income less KCS acquisition-related costs (as defined above) prior to the Control Date. For the year ended December 31, 2023, CPKC has presented the Non-GAAP measure of Core adjusted combined operating ratio, as defined above, to provide a comparison to prior period combined information calculated in a manner consistent with Article 11 as further adjusted to conform to CPKC’s core adjusted measures.

Critical Accounting Estimates

To prepare the Consolidated Financial Statements that conform with GAAP, the Company is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reported periods. Using the most current information available, the Company reviews estimates on an ongoing basis.

The development, selection and disclosure of these estimates, and this Management's Discussion and Analysis of Financial Condition and Results of Operations, have been reviewed by the Board of Directors’ Audit and Finance Committee, which is composed entirely of independent directors.

Business Acquisition

As described in Item 8. Financial Statements and Supplementary Data, Note 11 Business acquisition and Note 12 Investment in KCS, the Company assumed control of KCS and commenced consolidation of KCS on the Control Date, accounting for the acquisition as a business combination achieved in stages.

In accounting for the business combination, the Company’s previously held interest in KCS was remeasured to its Control Date fair value. The identifiable assets acquired, and liabilities and non-controlling interest assumed are measured at their provisional fair values at the Control Date, with certain exceptions, including income taxes and contract liabilities. The results from operations and cash flows are consolidated in the financial statements.

The disclosure of the business acquisition presented in Item 8. Financial Statements and Supplementary Data, Note 11 Business acquisition is prepared on a provisional basis using the best available information at this time. A provisional purchase price allocation was determined at the Control Date and has been revised at December 31, 2023 for identified measurement period adjustments. This provisional purchase price allocation may be subject to further adjustment during the remainder of the measurement period resulting in additional assets or liabilities being recognized to reflect new information obtained about facts and circumstances that existed as of the Control Date that, if known, would affect the amounts recognized as of that date. The measurement period is not to exceed a year. Changes to the provisional amounts may impact the amount of goodwill recognized. Goodwill is the residual

value after allocating the fair value of KCS to the assets acquired and liabilities and non-controlling interest assumed, i.e. it represents the excess of the purchase price over the fair value of the identifiable net assets.

Accounting for a business acquisition requires significant judgement to determine the estimated fair value of long-lived assets, intangible assets and assumed liabilities as at the acquisition date. The estimated fair values assigned to tangible and intangible assets acquired and liabilities assumed are based on management's estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. Estimates and assumptions include, but are not limited to, the cash flows an asset is expected to generate in the future and the appropriate weighted average cost of capital as at the Control Date, including market data, historical and future cash flow estimates, growth rates and discount rates.

The Company believes the fair value of KCS and the provisional fair values of the assets acquired and the liabilities and non-controlling interest assumed are based on reasonable assumptions and reflect known information and estimates. Measurement uncertainty in these estimates exists due to the characteristics of the assumptions and facts used to generate these estimates. Changes to assumptions and estimates during the measurement period could materially change the fair value estimates of the assets and liabilities included in the provisional purchase price allocation, and could change the recognized amount of goodwill. In addition, alternative estimates or assumptions could have been used in the establishment of the fair value of KCS and the provisional fair values of the assets acquired and liabilities assumed, including goodwill.

The table below outlines the sensitivities of key estimates or changes in those key estimates that management believes could result from new and more precise information relating to facts and conditions as of the Control Date. The table includes estimates of the related impacts to the provisional fair values:
