*Disclosure Controls and Procedures*

The United States Securities and Exchange Commission (the "Commission") defines "disclosure controls and procedures" as controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission's rules and forms.

After evaluating the effectiveness of Canadian National Railway Company's disclosure controls and procedures as of the end of the fiscal year covered by this report, Canadian National Railway Company's President and Chief Executive Officer (the "CEO") and its Executive Vice President and Chief Financial Officer (the "CFO") have concluded that Canadian National Railway Company's disclosure controls and procedures were effective as of the end of the fiscal year covered by this report.

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

The report of management on our internal control over financial reporting is located under the heading "Management's Report on Internal Control Over Financial Reporting" in our audited consolidated financial statements, which are filed as Exhibit 99.2 to this annual report on Form 40-F, and is incorporated by reference herein.

*Attestation Report of the Registered Public Accounting Firm*

The SEC has indicated that the designation or identification of Mr. Robert Knight as an audit committee financial expert does not deem him an "expert" for any purpose, impose any duties, obligations or liability on Mr. Knight that are greater than those imposed on members of the audit committee and board of directors who do not carry this designation or identification, or affect the duties, obligations or liability of any other member of the audit committee or board of directors.

**MINE SAFETY DISCLOSURE**

Not applicable.

**DISCLOSURE REGARDING FOREIGN JURISDICTIONS THAT PREVENT INSPECTIONS**

Not applicable.

**CORPORATE GOVERNANCE PRACTICES**

The Registrant's board of directors has reviewed the Registrant's corporate governance practices in response to the U.S. Sarbanes-Oxley Act of 2002, applicable rules of the U.S. Securities and Exchange Commission, as well as the NYSE Corporate Governance Standards (the "NYSE Standards"). Except as disclosed on its website, the Registrant's corporate governance practices do not differ significantly from that followed by U.S. domestic companies under the NYSE Standards. A discussion of differences is available at the Registrant's Internet website, www.cn.ca under the caption "Delivering Responsibly / Governance".

Except as otherwise indicated in this Annual Information Form (**AIF**), the information contained herein is given as of December 31, 2025. As used herein, references to the **Company** or **CN**, or **we** or **us** refer to Canadian National Railway Company and, as the context requires, its wholly-owned subsidiaries.

All references in this AIF to **dollars** or **$** are to Canadian dollars and all financial information reflected herein is determined on the basis of, and prepared in accordance with, United States generally accepted accounting principles (**GAAP**), unless otherwise indicated.

Certain statements included in this AIF or incorporated by reference herein are "forward-looking statements" within the meaning of the *United States Private Securities Litigation Reform Act of 1995* and under Canadian securities laws, including statements based on management's assessment and assumptions and publicly available information with respect to CN. By their nature, forward-looking statements involve risks, uncertainties and assumptions. CN cautions that its assumptions may not materialize and that current economic conditions render such assumptions, although reasonable at the time they were made, subject to greater uncertainty. Forward-looking statements may be identified by the use of terminology such as "believes," "expects," "anticipates," "assumes," "outlook," "plans," "targets," "goals," or other similar words.

Forward-looking statements are not guarantees of future performance and involve risks, uncertainties and other factors which may cause actual results, performance or achievements of CN to be materially different from the outlook or any future results, performance or achievements implied by such statements. Accordingly, readers are advised not to place undue reliance on forward-looking statements. Important risk factors that could affect the forward-looking statements include, but are not limited to, general economic and business conditions, including factors impacting global supply chains such as pandemics and geopolitical conflicts or tensions; trade restrictions, trade barriers, or the imposition of tariffs or other changes to international trade arrangements; industry competition; inflation, currency and interest rate fluctuations; changes in fuel prices; legislative and/or regulatory developments; compliance with environmental laws and regulations; actions by regulators and other regulatory claims or proceedings; increases in maintenance and operating costs; security threats; reliance on technology and related cybersecurity risk; transportation of hazardous materials; various events which could disrupt operations, including illegal blockades of rail networks, and natural events such as severe weather, droughts, fires, floods and earthquakes; climate change; labor negotiations and disruptions; environmental claims; uncertainties of investigations, proceedings and other types of claims and litigation; risks and liabilities arising from derailments; timing and completion of capital programs; the availability of and cost competitiveness of renewable fuels and the development of new locomotive propulsion technology; reputational risks; supplier concentration; pension funding requirements and volatility; and other risks detailed from time to time in reports filed by CN with securities regulators in Canada and the United States (**U.S.**). Reference should be made to the discussion of business risks in CN's 2025 Management's Discussion and Analysis (**MD&A**) for detailed information on major risk factors. The MD&A may be found online on SEDAR+ at <u>www.sedarplus.ca</u>, on the U.S. Securities and Exchange Commission's (**SEC**) website at <u>www.sec.gov</u> through EDGAR, and on CN's website at <u>www.cn.ca</u> in the "Investors" section.

CN has sustainability-related commitments and climate goals, and continues to assess the impact on its operations of related initiatives, plans and proposals that CN and other stakeholders (including government, regulatory and other bodies) are pursuing in relation to climate change and carbon emissions. The achievement of CN's climate goals is subject to several risks and uncertainties, including those disclosed in the section entitled "Reputation" in the Business risks discussion located on pages 65 to 66 of the MD&A. The achievement of these goals is also subject to circumstances outside of the Company's control, including the availability and cost competitiveness of renewable fuels and the development and availability of new technologies, such as alternative propulsion locomotive

technologies, and the cooperation of third parties such as suppliers, customers, supply chain partners and regulators. There can be no certainty that the Company will achieve any or all of these goals within the stated timeframe, or that achieving any of these goals will meet all of the expectations of its stakeholders or applicable legal requirements. If the Company is unable to achieve its climate goals or satisfy the expectations of its stakeholders, its brand and reputation could be materially and adversely affected.

Forward-looking statements reflect information as of the date on which they are made. CN assumes no obligation to update or revise forward-looking statements to reflect future events, changes in circumstances, or changes in beliefs, unless required by applicable securities laws. In the event CN does update any forward-looking statement, no inference should be made that CN will make additional updates with respect to that statement, related matters, or any other forward-looking statement.

**Other than in instances where CN specifically provides otherwise, information contained on, or accessible through, our website is not incorporated by reference in this AIF.**

CN has undertaken various initiatives over the course of the last three years to continuously further the general development of its business, including acquisitions and business combinations, financial management initiatives, and other corporate initiatives, as further described below.

**Significant transactions**

***Cape Breton & Central Nova Scotia Railway***

On November 1, 2023, the Company acquired from Genesee & Wyoming Inc. a stake in the Cape Breton & Central Nova Scotia Railway, a Class III short-line railroad that owns approximately 150 route miles. CN paid $78 million in cash, net of cash acquired and including working capital adjustments.

***Transfer of ownership of Quebec Bridge***

On May 8, 2024, CN entered into an agreement to transfer the ownership and related risks and obligations of a road, rail, and pedestrian bridge known as the Quebec Bridge located in Quebec, Canada, to the Government of Canada for a nominal amount. On November 12, 2024, the transaction was completed. CN retains requisite rights to occupy and operate the portion of the bridge where the rail infrastructure is located and will pay an annual occupancy fee over a term that also includes a noncancellable period.

***Acquisition of Iowa Northern Railway Company***

On December 6, 2023, the Company acquired the shares of the Iowa Northern Railway Company (**IANR**), a Class III short-line railroad that owns and leases approximately 175 route miles in northeast Iowa that are connected to CN's U.S. rail network. CN paid US$230 million ($312 million), including transaction costs to date. IANR serves upper Midwest agricultural and industrial markets covering many goods, including biofuels and grain. This transaction represents a meaningful opportunity to support the growth of local business by creating single-line service to North American destinations, while preserving access to existing carrier options.

The shares of IANR were deposited into an independent voting trust while the U.S Surface Transportation Board (**STB**) considered the Company's application to acquire control of IANR. During the trust period, IANR continued to be operated under its current management and the Company could not exercise day-to-day control.

On January 14, 2025, the STB issued a final decision approving CN's application to acquire control of IANR, subject to certain conditions. The Company assumed control of IANR on March 1, 2025.

**Financial management initiatives**

***Revolving credit facilities***

The Company has two unsecured revolving credit facilities with a consortium of lenders.

The unsecured credit facility of $2.5 billion is available for general corporate purposes and backstopping the Company's commercial paper programs. The facility consists of two tranches of $1.25 billion and was last amended on March 28, 2025 to extend the tenor of each tranche by one year to, respectively, March 31, 2028 and March 31, 2030. This revolving credit facility agreement is structured as a sustainability linked loan whereby its applicable margins are adjusted up or down based on the Company's performance under certain sustainability goals.

The unsecured credit facility of $1.0 billion is available for general corporate purposes, and was amended on March 28, 2025 to extend its tenor by one year to March 17, 2027.

Both credit facilities were amended in March 2023 to include fallback language addressing the cessation of Canadian Dollar Offered Rate (**CDOR**) and adoption of the Canadian Overnight Repo Rate Average (**CORRA**) as the alternative benchmark. Accordingly, on March 28, 2024, the Company amended both credit facilities to transition from CDOR to CORRA. The credit facilities provide borrowings at various benchmark interest rates, such as the Secured Overnight Financing Rate (**SOFR**) and CORRA, plus applicable margins, based on CN's credit ratings.

Subject to the consent of the individual lenders, the Company may increase the revolving credit facilities by an additional $500 million each during their respective terms and to request an extension of the $2.5 billion credit facility once a year to maintain the tenors of three year and five year of the respective tranches.

Both revolving credit facility agreements have one financial covenant, which limits debt as a percentage of total capitalization. As at December 31, 2025, the Company was in compliance with its financial covenant and had no outstanding borrowings under these revolving credit facilities.

***Equipment loans***

The Company has various secured non-revolving term loan credit facilities for financing or refinancing the purchase of equipment. The equipment loans made under the non-revolving credit facilities have a tenor at inception varying from 15 to 20 years and are secured by rolling stock.

On March 31, 2023, the Company entered into new loan supplements to its existing agreement for an additional principal amount of US$304 million, which was available to be drawn, in Canadian or U.S. dollars, through March 31, 2024. The Company drew on such facilities on March 22, 2024.

In addition, on November 3, 2023, the Company entered into a new term loan facility for a principal amount of $366 million, which was available to be drawn through November 4, 2024. The Company drew on such facility on October 29, 2024.

On March 31, 2023, outstanding loans referencing the London Interbank Offered Rate (**LIBOR**) were transitioned to SOFR. The facilities also included fallback language that addressed the cessation of CDOR and adoption of CORRA as the alternative benchmark and accordingly, on March 21, 2024, the Company amended certain of its non-revolving term loan facilities to transition from CDOR to CORRA. Borrowings under the non-revolving term loan facilities are provided at SOFR or CORRA plus applicable margins.

#### 5
*2025 Annual Information Form*

The Company repaid $88 million, $63 million and $41 million of its equipment loans in 2025, 2024 and 2023, respectively. As at December 31, 2025, the Company had outstanding borrowings of $1,329 million, at a weighted-average interest rate of 3.85% and had no further amounts available to be drawn under these facilities.

***Commercial paper***

The Company has a commercial paper program in Canada and in the U.S. Both programs are backstopped by the Company's $2.5 billion revolving credit facility. The maximum aggregate principal amount of commercial paper that can be issued is $2.5 billion, or the U.S. dollar equivalent, on a combined basis.The commercial paper programs, which are subject to market rates in effect at the time of financing, provide the Company with a flexible financing alternative, and can be used for general corporate purposes. The cost of commercial paper and access to the commercial paper market in Canada and the U.S. are dependent on credit ratings and market conditions. If the Company were to lose access to its commercial paper program for an extended period of time, the Company could rely on its revolving credit facilities to meet its short-term liquidity needs.

The Company had total commercial paper borrowings of US$90 million ($124 million), US$501 million ($721 million) and US$1,360 million ($1,801 million) as at December 31, 2025, 2024 and 2023, respectively.

***Accounts receivable securitization program***

The Company has an agreement to sell an undivided co-ownership interest in a revolving pool of accounts receivable to unrelated trusts for maximum cash proceeds of $450 million. On March 28, 2025, the Company extended the term of its agreement by one year to February 2, 2027. The trusts are multi-seller trusts and the Company is not the primary beneficiary. Funding for the acquisition of these assets is customarily through the issuance of asset-backed commercial paper notes by the unrelated trusts.

The Company has retained the responsibility for servicing, administering and collecting the receivables sold. The average servicing period is approximately one month and the interest on borrowings under the accounts receivable securitization program is renewed based on commercial paper rates then in effect, or CORRA or SOFR if the commercial paper market is inaccessible. Subject to customary indemnifications, each trust's recourse is limited to the accounts receivable transferred.

The accounts receivable securitization program provides the Company with readily available short-term financing for general corporate use. In the event the program is no longer available before its scheduled maturity, the Company expects to meet its future payment obligations through its various sources of financing including its revolving credit facilities and commercial paper program, and/or access to capital markets.

During the years ended December 31, 2025 and 2023, the Company had no proceeds from the accounts receivable securitization program and no repayments and had no outstanding borrowings under the accounts receivable securitization program. During the year ended December 31, 2024, the Company had proceeds from the accounts receivable securitization program of $450 million and repayments of $450 million and had no outstanding borrowings under the accounts receivable securitization program.

***Bilateral letter of credit facilities***

The Company has a series of committed and uncommitted bilateral letter of credit facility agreements. On March 28, 2025, the Company extended the maturity date of its committed bilateral letter of credit facility agreements to April 28, 2028. The agreements are held with various banks to support the Company's requirements to post letters of credit in the ordinary course of business. Under these agreements, the

#### 6
*2025 Annual Information Form*

Company has the option from time to time to pledge collateral in the form of cash or cash equivalents, for a minimum term of one month, equal to at least the face value of the letters of credit outstanding.

As at December 31, 2025, the Company had outstanding letters of credit of $321 million under the committed facilities from a total available amount of $362 million and 153 million under the uncommitted facilities.

***Normal Course Issuer Bid (NCIB)***

On January 24, 2023, the Board of Directors approved a NCIB for the repurchase of up to 32.0 million common shares between February 1, 2023 and January 31, 2024.

On January 23, 2024, the Board of Directors approved a NCIB for the repurchase of up to 32.0 million common shares between February 1, 2024 and January 31, 2025.

On January 30, 2025, the Board of Directors approved a new NCIB, which allows for the repurchase of up to 20.0 million common shares between February 4, 2025 and February 3, 2026.

On January 30, 2026, the Company announced that the Board of Directors approved a new NCIB, which allows for the repurchase of up to 24.0 million common shares between February 4, 2026 and February 3, 2027.

***Reinvestment in the business***

In 2023, CN spent approximately $3.2 billion in its capital program, of which $1.6 billion was invested to maintain the safety and integrity of its network, particularly track infrastructure. CN's capital spending also included $0.9 billion for strategic initiatives to increase capacity, enable growth and improve network resiliency, including line capacity upgrades and information technology initiatives, and $0.7 billion on equipment, including the acquisition of 500 new grain hopper cars.

In 2024, CN spent approximately $3.5 billion in its capital program, of which $1.7 billion was invested to maintain the safety and integrity of its network, particularly track infrastructure. CN's capital spending also included $1.0 billion for strategic initiatives to increase capacity, enable growth and improve network resiliency, including line capacity upgrades and information technology initiatives, and $0.8 billion on equipment, including the acquisition of 750 new grain hopper cars.

In 2025, CN spent approximately $3.7 billion in its capital program, of which $1.8 billion was invested to maintain the safety and integrity of its network, particularly track infrastructure. CN's capital spending also included $1.4 billion for strategic initiatives to increase capacity, enable growth and improve network resiliency, including line capacity upgrades and information technology initiatives, and $0.5 billion on equipment.

***Shelf prospectus and registration statement***

On May 4, 2022, the Company filed a new shelf prospectus with Canadian securities regulators and a registration statement with the SEC, pursuant to which CN could issue up to $6.0 billion of debt securities in the Canadian and U.S. capital markets over a 25-month period following the filing date (collectively, the **2022 shelf prospectus**).

On May 10, 2023, under the 2022 shelf prospectus, the Company issued $550 million 4.15% Notes due 2030, $400 million 4.40% Notes due 2033 and $800 million 4.70% Notes due 2053 in the Canadian capital markets.

#### 7
*2025 Annual Information Form*

On November 1, 2023, under the 2022 shelf prospectus, the Company issued US$300 million ($416.25 million) 5.85% Notes due 2033 and US$300 million ($416.25 million) 6.125% Notes due 2053 in the U.S capital markets.

On April 2, 2024, the Company filed a shelf prospectus with Canadian securities regulators and a registration statement with the SEC, pursuant to which CN may issue debt securities in the Canadian and U.S. capital markets over a 25-month period following the filing date (collectively, the **2024 shelf prospectus**). This shelf prospectus and registration statement replaces CN's 2022 shelf prospectus and registration statement that was set to expire on June 4, 2024.

On May 2, 2024, under the 2024 shelf prospectus and registration statement, the Company issued $700 million 4.60% Notes due 2029 and $550 million 5.10% Notes due 2054 in the Canadian capital markets.

On September 18, 2024, under the 2024 shelf prospectus and registration statement, the Company issued US$750 million ($1,020 million) 4.375% Notes due 2034 in the U.S capital markets.

On June 10, 2025, under the 2024 shelf prospectus and registration statement, the Company issued $500 million 3.50% Notes due 2030 and $500 million 4.20% Notes due in 2035 in the Canadian capital markets.

On November 12, 2025, under the 2024 shelf prospectus and registration statement, the Company issued US$300 million ($421 million) 4.20% Notes due 2031 and US$400 million ($561 million) 4.75% Notes due 2035 in the U.S. capital markets.

Access to the Canadian and U.S. capital markets under the shelf prospectus and registration statement is dependent on market conditions. The Company's access to long-term funds in the capital markets depends on its credit ratings and market conditions. The Company believes that it continues to have access to the capital markets. If the Company were unable to borrow funds at acceptable rates in the capital markets, the Company could borrow under its credit facilities, draw down on its accounts receivable securitization program, access the pledged cash under its letter of credit facilities, raise cash by disposing of surplus properties or otherwise monetizing assets, reduce discretionary spending or take a combination of these measures to assure that it has adequate funding for its business.

For more information on the Company's capital markets transactions completed in 2025, please refer to the section entitled "Prior Sales" on page 21 of this AIF.

**Labor matters**

Many of our employees in Canada and the U.S. are unionized and are covered by collective agreements. CN is involved in several ongoing negotiations concerning labor matters, including the negotiation of new collective agreements as described below. There can be no assurance that the Company will be able to reach a tentative agreement without a strike or lockout or that the resolution of these negotiations, or the outcome of any arbitration or litigation, will not have a material adverse effect on the Company's results of operations or financial position.

The Company's existing collective agreements remain in effect until the bargaining process outlined under the Canada Labor Code or the U.S. Railway Labor Act has been exhausted.

For a further discussion of CN's labor negotiations, please see the section entitled "Labor and workforce negotiations" in the 2025 Highlights discussion located on page 7 of the MD&A, which section is incorporated by reference herein.

***Canadian workforce***

*<u>Teamsters Canada Rail Conference</u>* (**TCRC**) - On May 26, 2023, the collective agreement with TCRC was ratified by its members, renewing the collective agreement for a one-year term, retroactive to January 1, 2023. This agreement expired on December 31, 2023.

As a result, on November 27, 2023, CN commenced negotiations with the TCRC. On February 16, 2024, CN filed a Notice of Dispute, causing the Minister of Labor to appoint a conciliator. On May 9, 2024, the Minister of Labor requested clarity from the Canadian Industrial Relations Board (**CIRB**) on whether or not any services provided by TCRC-represented employees were essential and therefore needed to be maintained during a labor disruption. On August 9, 2024, the CIRB ruled that none of those services were essential within the meaning of the law. On August 18, 2024, CN issued a notice to the TCRC formally advising them of its intention to lock out employees. On August 22, 2024, CN proceeded with the lockout, which was revoked less than 24 hours after, following the Minister of Labor's direction to the CIRB to order the parties to end the lockout, return employees to work, resolve outstanding issues in binding interest arbitration and extend the collective agreements until the arbitration process is complete. On August 23, 2024, the TCRC served CN with a 72-hour strike notice. On August 24, 2024, the CIRB issued an order consistent with the Minister's directive, which indicated that there can be no labor stoppage, including a lockout or strike, during the arbitration process. On April 7, 2025, an arbitrator issued a binding decision, setting the terms of a new three-year collective agreement between CN and TCRC. The three-year agreement covers approximately 6,000 conductors, conductor trainees, yard coordinators and locomotive engineers across CN's network in Canada and is retroactively effective beginning January 1, 2024 until December 31, 2026.

*<u>International Brotherhood of Electric Workers</u>* (**IBEW**) *-* On September 5, 2024, the IBEW served notice to commence bargaining for the renewal of the collective agreement with CN which expired on December 31, 2024.

The Minister of Labor had appointed conciliation officers to assist the parties in reaching an agreement. On January 28, 2025, the parties reached a four-year tentative agreement. On February 14, 2025, the new collective agreement with the IBEW was ratified. The four-year agreement covers approximately 750 Signals and Communications employees in Canada until December 31, 2028.

*<u>Unifor</u>* - On May 1, 2023, the collective agreement with Unifor was ratified by its members, renewing the collective agreement for a two-year term, retroactive to January 1, 2023, which then expired on December 31, 2024. On December 22, 2024, the new collective agreements with Unifor were ratified by CN employees. The four-year agreements cover approximately 3,300 employees across Canada working in various departments such as Mechanical, Intermodal, Facility Management, and in clerical positions until December 31, 2028.

Canadian National Transportation Limited (**CNTL**) - On January 17, 2024, CNTL, a wholly-owned subsidiary of the Company, reached a tentative agreement with owner-operators affiliated with Unifor. On May 14, 2024, the new collective agreement with Unifor was ratified by employees of CNTL. This four-year agreement covers approximately 750 owner-operator truck drivers in Canada under contract with CNTL until December 31, 2027.

*<u>United Steel Workers Union</u>* (**USW**) *-* On September 6, 2023, USW served notice to commence bargaining for the renewal of the collective agreement with the Company which expired on December 31, 2023.

*2025 Annual Information Form*

***U.S. workforce***

The general approach to labor negotiations by U.S. Class I railroads is to bargain on a collective national basis with the industry, which CN's subsidiaries Grand Trunk Western Railroad Company (**GTW**), companies owned by Illinois Central Corporation (**ICC**), Wisconsin Central Ltd. (**WC**), and Bessemer & Lake Erie Railroad Company (**BLE**) currently participate in for collective bargaining agreements covering all union-represented employees, with the exception of two employee groups working at Pittsburgh and Conneaut Dock Company (**PCD**). On November 1, 2024, the National Carriers Conference Committee (**NCCC**) served a Section 6 notice pursuant to the Railway Labor Act (**RLA**), which officially opened collective bargaining for the freight industry. As of February 4, 2026, agreements have been reached and ratified with eleven unions and negotiations continue with the remaining one union. There can be no strike or lockout until such time as the parties have failed to reach voluntary agreements and all dispute resolution mechanisms of the RLA have been exhausted. While negotiations are ongoing and until all RLA provisions have been exhausted, all existing contract terms remain in place.

---

**4.1 *OVERVIEW***

CN is engaged in the rail and related transportation business and powers the economy by safely transporting more than 300 million tons of natural resources, manufactured products, and finished goods throughout North America every year for its customers. With its nearly 20,000-mile rail network and related transportation services, CN connects Canada's Eastern and Western coasts with the U.S. Midwest and the U.S. Gulf Coast, contributing to sustainable trade and the prosperity of the communities in which it operates since 1919.

CN's freight revenues are derived from seven commodity groups representing a diversified and balanced portfolio of goods transported between a wide range of origins and destinations. This product and geographic diversity better position the Company to face economic fluctuations and enhances its potential for growth opportunities. For the year ended December 31, 2025, CN's largest commodity group, Intermodal, accounted for 22% of total revenues. From a geographic standpoint, 37% of revenues relate to overseas traffic, 29% to transborder traffic, 18% to Canadian domestic traffic and 16% to U.S. domestic traffic. The Company is the originating carrier for over 85%, and the originating and terminating carrier for over 65%, of traffic moving along its network, which allows it both to capitalize on service advantages and build on opportunities to efficiently use assets.

Revenues generated by the Company during the year are influenced, among other things, by seasonal weather conditions, general economic conditions, cyclical demand for rail transportation and competitive forces in the transportation marketplace. Operating expenses reflect the impact of freight volumes, seasonal weather conditions, labor costs, fuel prices, and the Company's productivity initiatives.

**4.2 *COMMODITY GROUPS***

For a description of the various commodity groups transported by CN, their principal markets, as well as select revenue, revenue ton miles (**RTMs**) and carload information, please see pages 21 to 26 of the MD&A, which pages are incorporated by reference herein.

**4.3 *COMPETITIVE CONDITIONS***

For a discussion of the competitive conditions under which CN operates, please see the section entitled "Competition" in the Business risks discussion located on page 58 of the MD&A, which section is incorporated by reference herein.

#### 10
*2025 Annual Information Form*

**4.4 *LABOR***

As at December 31, 2025, CN employed a total of 23,839 employees, of which 18,078 were unionized employees.

For more information on recent labor developments within our Canadian and U.S. workforce, please see the section entitled "General Developments Over the Past Three Years" beginning on page 4 of this AIF. For a discussion on CN's labor negotiations, please see the section entitled "Labor and workforce negotiations" in the 2025 Highlights discussion located on page 7 of the MD&A, which section is incorporated by reference herein.

**4.5 *SOCIAL POLICIES***

CN has adopted a number of policies in support of its commitment to *Delivering Responsibly*. These policies include namely:

&nbsp;&nbsp;&nbsp;&nbsp;· Various CN policies against workplace
 harassment, violence, and discrimination;

&nbsp;&nbsp;&nbsp;&nbsp;· the Code of Business Conduct;

&nbsp;&nbsp;&nbsp;&nbsp;· the Supplier Code of Business Conduct;
 and

&nbsp;&nbsp;&nbsp;&nbsp;· CN's Indigenous Relations Policy.

**Policies Against Workplace Harassment, Violence and Discrimination**

In addition to its Employment Equity Policy (for Canadian employees) and Equal Employment Opportunity Policy (for U.S. employees), CN maintains a comprehensive Human Rights Policy, a Workplace Harassment and Violence Prevention Policy for its Canadian employees, and a Workplace Violence Prevention Policy and a Prohibited Harassment, Discrimination and Anti-Retaliation Policy for its U.S. employees. These policies affirm CN's commitment to providing employees with a safe, respectful and violence-free workplace and to preventing harassment and discrimination against any employee or applicant. The policies against harassment and discrimination extend to recruitment, selection and compensation practices, as well as to working conditions and the work environment.

Internal complaint resolution procedures have been established whereby any person covered by the policies can contact the appropriate member of the human resources team who will address the employee's complaint. The employee can also call either the Human Resources Center, which will forward the complaint to the appropriate human resources manager for further handling, or the CN Ombudsman directly on a confidential basis. In Canada, all harassment complaints are submitted to CN's Designated Recipient in accordance with the Canada Labour Code *Regulations on Work Place Harassment and Violence Prevention*.

**Code of Business Conduct**

CN has adopted a Code of Business Conduct, which applies to all directors, officers and employees of the Company. The Code of Business Conduct affirms CN's commitment to the highest ethical standards. It addresses a number of matters, including, without limitation, conflicts of interest, compliance with laws and reporting of any illegal or unethical behavior. Each director, executive officer and management employee must certify annually their compliance with the Code of Business Conduct.

Management periodically reports to the Governance and Sustainability Committee on the implementation of the Code of Business Conduct and, as applicable, on any significant violations thereof. Yearly, the CN Ombudsman presents a report that summarizes issues reported under the Code of Business Conduct and handled by the Office of the Ombudsman to the Governance and Sustainability Committee. The Code of Business Conduct is regularly reviewed, including most recently in 2024, to ensure that it continues to

#### 11
*2025 Annual Information Form*

adhere to CN's core values of integrity and respect as well as to ensure that it remains consistent with industry standards and trends.

**Supplier Code of Conduct**

CN has adopted a Supplier Code of Conduct, which extends the principles of our Code of Business Conduct and Human Rights Policy to our suppliers, agents, consultants and other third parties and business partners, and their respective employees, directors and officers (collectively, **Suppliers**).

The Supplier Code of Conduct affirms our commitment to doing the right thing and to working with Suppliers who are also dedicated to being socially, ethically and environmentally responsible. The Supplier Code of Conduct sets forth the standards of ethical conduct expected from our Suppliers. It aims to ensure, among other matters, that we continue to work with Suppliers who comply with all applicable laws (including applicable employment laws, anti-bribery, anti-corruption and antitrust laws, and data protection and privacy laws and regulatory requirements), prohibit the use of forced and child labor in their operations, promote an inclusive and safe work environment, and are conscious of their environmental impact and focus on building positive community relations (including with Indigenous peoples) when conducting their operations.

**Indigenous Relations Policy**

In early 2024, CN released its new Indigenous Relations Policy, which builds on CN's commitment to reconciliation and Indigenous engagement in Canada. This Policy outlines CN's commitment to developing respectful, sustainable and mutually beneficial relationships with Indigenous peoples across its network in Canada. The Policy sets out the guiding principles that underpin CN's approach to Indigenous reconciliation in Canada.

All CN personnel are expected to follow the guidelines set forth in the Indigenous Relations Policy when performing work for CN, and non-compliance with the Indigenous Relations Policy may be reported by CN personnel on a confidential basis to their supervisor, their human resources representative, the CN Law Department, or the CN Ombudsman.

In late 2024, CN released its first Indigenous Reconciliation Action Plan (**IRAP**) reaffirming its commitment to strengthen ties with Indigenous communities, foster mutually beneficial relationships, and create opportunities for meaningful collaboration on the journey toward genuine reconciliation. The IRAP commitments and actions were developed and shaped by the insights, priorities, and feedback received from Indigenous communities and CN employees that engage with these communities. CN's IRAP outlines concrete steps, measurable commitments, and a clear vision to guide CN on its reconciliation journey over three years, in Canada. Through this plan, CN aims to build sustainable, respectful, and long-term partnerships with Indigenous peoples. The IRAP is structured around five pillars: (i) Cultural Awareness and Employee Engagement; (ii) People and Employment; (iii) Economic Reconciliation; (iv) Community Engagement and Relationships; and (v) Environmental Stewardship, Safety and Sustainability. CN will publish an annual report of its progress on the IRAP actions, with the first such annual report expected to be released in the first quarter of 2026.

**4.6 *REGULATION***

CN's operations are subject to regulations both in Canada and in the U.S. A summary of the regulations material to CN's business and operations as well as recent significant regulatory developments that are relevant to CN is provided hereinafter.

For a further discussion on the potential risks and contemplated impacts of pending legislative and other regulatory developments (both in Canada and in the U.S.) on our business, see the section entitled "Regulation" in the Business risks discussion located on pages 60 to 61 as well as the section entitled

#### 12
*2025 Annual Information Form*

**"**U.S. regulatory updates" in the 2025 Highlights discussion located on page 6 of the MD&A, which sections are incorporated by reference herein.

**Economic regulation - Canada**

The Company's rail operations in Canada are subject to economic regulation by the Canadian Transportation Agency (**CTA**) under the *Canada Transportation Act*. The CTA establishes regulations on various topics, including interswitching rates, insurance, and procedures for arbitration cases. The CTA adjudicates disputes between a shipper and carrier, including final offer arbitration for rate disputes and level of service disputes. The CTA also regulates the maximum revenue entitlement for the movement of regulated grain, charges for railway ancillary services, railway crossing and noise-related disputes, and discontinuance of service over a rail line. In addition, various Company business transactions must gain prior regulatory approval, with attendant risks and uncertainties, and the Company is subject to government oversight with respect to rate, service and business practice issues.

**Economic regulation - U.S.**

The Company's U.S. rail operations are subject to economic regulation by the STB. The STB serves as both an adjudicatory and regulatory body and has exclusive jurisdiction over certain railroad rate and service issues, and carrier practices. It also has jurisdiction over the situations and terms under which one railroad may use another railroad's traffic or facilities, the construction, acquisition or abandonment of rail lines, railroad consolidations, and labor protection provisions in connection with the foregoing. As such, various Company business transactions must gain prior regulatory approval and aspects of its pricing and service practices may be subject to challenge, with attendant risks and uncertainties.

Government regulation of the railroad industry is a significant determinant of the competitiveness and profitability of railroads. Deregulation of certain rates and services, plus the ability to enter into confidential contracts pursuant to the *Staggers Rail Act of 1980* has substantially increased the flexibility of railroads to respond to market forces and has resulted in highly competitive rates. Additional regulation, changes in regulation and re-regulation of the industry through legislative, administrative, judicial or other action could materially affect the Company.

***Reciprocal switching***

On April 30, 2024, the STB issued a final rule for reciprocal switching for inadequate service. The STB's new rule allows customers to obtain reciprocal switching access to an alternate carrier in a terminal area if the incumbent railroad's service falls below one of three objective metrics (original estimated time of arrival, transit time, and first-mile/last-mile service) and if certain other conditions are met. Any prescribed reciprocal switching arrangement for a facility in the United States would be effective for a period between three to five years and could be renewed. On May 10, 2024, the Company and two other railroads filed a petition for review of the rule with the U.S. Court of Appeals for the Seventh Circuit. On July 8, 2025, the U.S. Court of Appeals for the Seventh Circuit vacated the STB's reciprocal switching rule, following a petition for review filed by the Company and two other railroads. The decision became effective on September 2, 2025. On January 7, 2026, the STB proposed to repeal its existing regulations on prescription of reciprocal switching, which require a showing of anticompetitive conduct, and replace them with case-by-case adjudication under the statutory standards established by Title 49 of the United States Code (Transportation).

***Crew size***

On April 9, 2024, the Federal Railroad Administration (**FRA**) issued a final rule establishing minimum requirements for the size of train crews depending on the type of operation. The FRA's new rule requires railroad operations to have a minimum of two crew members, except in certain circumstances, including remote-control operations. The rule includes a process to petition the FRA for special approval to operate

#### 13
*2025 Annual Information Form*

with fewer than two crew members. The rule became effective on June 10, 2024. The rail industry has challenged the rule as arbitrary and contrary to law in federal circuit court, which remains pending.

**Safety regulation – Canada**

CN's operations are also subject to safety and environmental provisions relating to track standards, equipment standards, transportation of hazardous materials, environmental assessments and certain labor regulations. In Canada, CN's rail operations are subject to safety regulation by the Minister of Transport (**Minister**) under the *Railway Safety Act* (**RSA**) as well as the rail portions of other safety-related statutes, which are administered by Transport Canada (**TC**). TC is also empowered to conduct inspections, investigate, and enforce safety regulations under the RSA. The Company is often required to submit information to TC in compliance with regulations, including applications for a railway operating certificate.

In addition, CN may be legally required to transport dangerous goods and hazardous materials, including toxic inhalation hazard materials as a result of its common carrier obligations and, as such, is also subject to additional regulatory oversight in Canada under the *Transportation of Dangerous Goods Act* (**TDGA**), which is also administered by TC. The TDGA establishes the safety requirements for the transportation of goods classified as dangerous and enables the adoption of regulations for security training and screening of personnel working with dangerous goods, as well as the development of a program to require a transportation security clearance for dangerous goods, the tracking of dangerous goods during transport and the development of an emergency response plan.

**Safety regulation – U.S.**

The Company's U.S. rail operations are subject to safety regulation by the FRA under the *Federal Railroad Safety Act* as well as rail portions of other safety statutes, with the transportation of hazardous commodities also governed by regulations promulgated by the Pipeline and Hazardous Materials Safety Administration (**PHMSA**). The FRA has jurisdiction over railroad safety and equipment standards, and most rail safety regulation is handled at the federal level. The FRA requires submission of certain information from railroads, and railroads may be subject to inspection or audits by the FRA. A state may regulate rail safety unless the FRA has regulated the matter, or the state regulation is necessary to address a local condition, is consistent with federal law, and does not unduly burden interstate commerce. There is a risk that states could enact new laws in this regard that are intended to regulate rail safety more extensively.

PHMSA requires carriers operating in the U.S. to report annually the volume and route-specific data for cars containing hazardous commodities; conduct a safety and security risk analysis for each used route; identify a commercially practicable alternative route for each used route; and select for use the practical route posing the least safety and security risk. In addition, the Transportation Security Administration (**TSA**) requires rail carriers to provide upon request, location and shipping information on cars on their networks containing toxic inhalation hazard materials and certain radioactive or explosive materials; and ensure the secure, attended transfer of all such cars to and from shippers, receivers and other carriers that will move from, to, or through designated high-threat urban areas.

**Other regulations – Canada and U.S.**

***Vessels - U.S.***

CN's vessel operations are subject to regulation by the U.S. Coast Guard and the Department of Transportation, Maritime Administration, which regulate the ownership and operation of vessels operating on the Great Lakes and in U.S. coastal waters. In addition, in the U.S., the Environmental Protection Agency regulates air emissions from these vessels.

#### 14
*2025 Annual Information Form*

***Security - Canada***

In Canada, the Company is subject to border security regulation by the Canada Border Services Agency (**CBSA**). In particular, the Company is subject to border security arrangements pursuant to an agreement between the Company, Canadian Pacific Kansas City Limited (formerly known as Canadian Pacific Railway) and the CBSA.

The Company is also required to comply with regulations on agriculture-related shipments crossing the Canada/U.S. border which are mandated by the Canadian Food Inspection Agency in Canada.

***Security - U.S.***

The Company is subject to statutory and regulatory directives in the U.S. addressing homeland security concerns. In the U.S., the TSA regulates transportation security, which is part of the U.S. Department of Homeland Security (**DHS**) and PHMSA, which, like the FRA, is part of the U.S. Department of Transportation. Border security falls under the jurisdiction of U.S. Customs and Border Protection (**CBP**), which is part of the DHS. In particular, the Company is subject to regulations against terrorism, regulations imposed by the CBP requiring advance notification by all modes of transportation for all shipments into the U.S., potential security inspections at the Canada/U.S. border, and gamma ray screening of cargo entering the U.S. from Canada, among others.

The Company is also required to comply with regulations on agriculture-related shipments crossing the Canada/U.S. border, including inspection requirements for imported fruits and vegetables grown in Canada and an agricultural quarantine and inspection user fee for all traffic entering the U.S. from Canada, which are mandated by the U.S. Department of Agriculture and the Food and Drug Administration.

The Company has worked with the Association of American Railroads to develop and put in place an extensive industry-wide security plan to address terrorism and security-driven efforts by state and local governments seeking to restrict the routings of certain hazardous materials.

***Cybersecurity and technology - Canada & U.S.***

CN relies on information technology operated by it or under the control of third parties in all aspects of its business, and, as a result, is subject to regulations regarding cybersecurity and technology in both Canada and the U.S., including regulations specific to companies operating in the rail industry. In particular, CN is subject to cyber risk monitoring and assessment requirements, testing requirements, and reporting requirements.

CN has invested, and continues to invest in, technology security initiatives, information technology risk management, business continuity and disaster recovery plans, and other security and mitigation programs to meet evolving network and cybersecurity expectations and regulations. New regulatory obligations related to cybersecurity and technology risk may impose additional costs and obligations on CN and may lead to government inquiries or requests for information.

**4.7 *ENVIRONMENTAL MATTERS***

**Environmental Liability and Compliance**

A risk of environmental liability is inherent in railroad and related transportation operations; real estate ownership, operation or control; and other commercial activities of the Company with respect to both current and past operations. As a result, the Company incurs significant operating and capital costs, on an ongoing basis, associated with environmental regulatory compliance and clean-up requirements in its railroad operations and relating to its past and present ownership, operation or control of real property.

#### 15
*2025 Annual Information Form*

CN is in all material respects similarly situated relative to its competitors as it relates to its exposure to environmental liability risk and thus the resulting environmental protection requirements and expenditures are not expected to have a material adverse effect on CN's competitive position. Environmental expenditures that relate to current operations, or to an existing condition caused by past operations, are expensed as incurred. Environmental expenditures that provide a future benefit are capitalized.

In Canada, the matter of environmental permits is complex for CN because of the overlap between federal and provincial jurisdictions. When projects trigger an environmental assessment, CN proceeds in accordance with the *Impact Assessment Act*. Provincial and municipal environmental legislation may be applicable to CN if such legislation does not aim to regulate the management or operations of railways. CN does not apply systematically for provincial, municipal or local environmental permits for its railway operations in Canada. Because of the multiple jurisdictions, there can be no assurance that additional provincial, municipal or local environmental permits will not be required in the future and CN may incur additional expenses or changes in its operations those were to be required.

For a further discussion of environmental matters, refer to Note 21 *– Major commitments and contingencies* contained in CN's 2025 Annual Consolidated Financial Statements (**Financial Statements**), which note is incorporated by reference herein, as well as the section entitled "Environmental matters" in the Business risks discussion located on page 59 of the MD&A, which pages are incorporated by reference herein. The Financial Statements may be found online on SEDAR+ at <u>www.sedarplus.ca</u>, on the SEC's website at <u>www.sec.gov</u> through EDGAR, and on the Company's website at <u>www.cn.ca</u> in the "Investors" section.

**Environmental Policy**

CN is committed to building a sustainable future, to working with its supply chain partners and customers to provide cleaner, more sustainable transportation services, and to working with stakeholders and rightsholders to avoid, minimize, or offset its environmental impact and when required, to restore it. CN's Environmental Policy guides its environmental strategy, with a focus on emissions and energy efficiency, waste management, and biodiversity and land management. The Environmental Policy is regularly reviewed, including most recently in 2025. CN employees, suppliers, and contractors performing services on behalf of CN are expected to act in accordance with the Environmental Policy when performing work for CN. CN has also implemented comprehensive environmental management programs which establish the governance structure and processes it implements to support the environmental commitments set out in its Environmental Policy, with a view to minimize the risk and potential impacts of its activities on the environment and ensure compliance with applicable environmental regulations.

CN strives to contribute to the protection of the environment by integrating environmental priorities into its overall business plan and through the specific monitoring and measurement of such priorities against historical performance and, in some cases, specific goals. Certain risk mitigation strategies, such as periodic audits, employee training programs and emergency plans and procedures, are in place with the view of minimizing the environmental risks to the Company. The Safety and Environment Committee of the Board of Directors has the responsibility of overseeing the Company's Environmental Policy and environmental programs.

For further information, CN's most recent Delivering Responsibly report, data supplement report, as well as the Company's CDP report and the Company's Corporate Governance Manual are available on CN's website <u>www.cn.ca</u> in the "Delivering Responsibly" section.

#### 16
*2025 Annual Information Form*

**4.8 *LEGAL MATTERS***

**Legal Proceedings**

As of the date hereof, there are no legal proceedings to which CN is or was a party to during the last financial year, or that any of its property is or was the subject of during the last financial year, in each case involving claims for damages (exclusive of interest and costs) in excess of 10% of CN's current assets. The Company is not aware of any such legal proceedings being contemplated.

See Note 21 *– Major commitments and contingencies* to the Financial Statements, which note is incorporated by reference herein, for further discussion of material legal actions, if any.

**Indigenous Claims**

The Company believes that it possesses unrestricted and absolute title to its lands. However, in recent years, some Indigenous communities have claimed to have a continuing legal interest in certain lands. As the issues surrounding Indigenous claims are complex and involve not only private interests but fiduciary and other obligations of the Crown in the right of Canada, CN has agreed not to sell or otherwise dispose of land which is not essential to its rail operations and which is located in, or adjacent to, an Indigenous reserve, unless each of CN and the Government of Canada is satisfied that no legitimate Indigenous claim exists with respect to such land. CN has also agreed to convey to the Government of Canada, for no consideration, any land not integral to its rail operations that may be necessary to settle legitimate Indigenous claims with respect to such land, or lands which were formerly reserve lands and have become non-rail assets. The Government of Canada, for its part, has agreed that it will provide the necessary compensation for settlement of legitimate Indigenous claims which would otherwise result in CN having to relinquish land essential to its rail network, unless such claims arise out of, or are substantially based upon, willful, known, negligent or fraudulent acts or omissions of CN which adversely affected the rights or interests of Indigenous peoples. There is no perceived material adverse effect on the Company, as the right of the Company to continue to occupy and operate over such lands is not being called into question.

**4.9 *INTANGIBLE PROPERTIES***

CN uses various works protected by intellectual property rights which the Company owns or for which it has been granted rights to use. These works include customers' lists, copyrights, patents, trademarks, logos and trade names. This intellectual property is important to CN's operations and its success.

**4.10 *RISK FACTORS***

A description of material risks to CN and its business appears under the heading "Business risks" located on pages 58 to 66 of the MD&A, and under the heading "Financial Instruments" for risks associated with the Company's use of financial instruments located on pages 47 to 49 of the MD&A, which pages are incorporated by reference herein. See Item 1 of this AIF for a further discussion of risks associated with forward-looking statements.

|:---|:---|
| **ITEM 5** | **DIVIDENDS** |

---

CN has declared dividends in line with its overall financial performance and cash flow generation. The Board of Directors makes decisions on dividend levels on an annual basis and on dividend payout on a quarterly basis.

#### 17
*2025 Annual Information Form*

Consistent with this practice, the quarterly dividend rate has increased as follows during the three most recently completed financial years and for 2026:

---

| | |
|:---|:---|
| **Effective year** | **Amount of quarterly dividend (per common share)** |
| 2023 | $0.7900 |
| 2024 | $0.8450 |
| 2025 | $0.8875 |
| 2026 | $0.9150 |

---

There can be no assurance as to the amount or timing of such dividends in the future.

---

| | |
|:---|:---|
| **ITEM 6** | **CAPITAL STRUCTURE** |

---

**6.1 *GENERAL DESCRIPTION OF CAPITAL STRUCTURE***

The authorized share capital of CN consists of an unlimited number of common shares, an unlimited number of Class A Preferred Shares issuable in series and an unlimited number of Class B Preferred Shares issuable in series, all without par value. There are no Class A Preferred Shares or Class B Preferred Shares currently issued and outstanding.

**Common Shares**

The common shares carry and are subject to the following rights, privileges, restrictions and conditions:

***Voting -*** Each common share entitles its holder to receive notice of and to attend all general and special meetings of shareholders of CN, other than meetings at which only the holders of a particular class or series of shares are entitled to vote, and each such common share entitles its holder to one vote.

***Dividends -*** The holders of common shares are, at the discretion of the directors, entitled to receive, out of any amounts applicable to the payment of dividends, and after the payment of any dividends payable on any Class A Preferred Shares, Class B Preferred Shares or shares of any other class of the Company ranking prior to the common shares, any dividends declared and payable by CN on the common shares.

***Dissolution -*** The holders of common shares shall be entitled to share equally in any distribution of the assets of CN upon the liquidation, dissolution or winding-up of CN or other distribution of its assets among its shareholders for the purpose of winding-up its affairs. Such participation is subject to the rights, privileges, restrictions and conditions attaching to any issued and outstanding Class A Preferred Shares, Class B Preferred Shares or shares of any other class ranking prior to the common shares.

**Preferred Shares**

The Class A Preferred Shares and the Class B Preferred Shares are issuable in series and, subject to CN's Articles, the Board of Directors is authorized to fix, before issuance, the designation, rights, privileges, restrictions and conditions attaching to the shares of each series. The holders of Class A Preferred Shares or Class B Preferred Shares shall not be entitled to vote at meetings of shareholders otherwise than as provided by law and holders of Class A Preferred Shares or Class B Preferred Shares shall not be entitled to vote separately as a class except as provided by law.

#### 18
*2025 Annual Information Form*

**6.2 *SHARE OWNERSHIP CONSTRAINTS***

CN's Articles provide that no person, together with their associates, shall hold, beneficially own or control, directly or indirectly, more than 25% of the issued and outstanding voting shares of the Company (**share ownership constraint**).

Where the total number of voting shares held, beneficially owned or controlled, directly or indirectly, by any one person together with his or her associates exceeds 25% of the issued and outstanding voting shares of the Company, no person shall exercise the voting rights attached to the voting shares held, beneficially owned or controlled, directly or indirectly, by such person or their associates. All dividends attributable to the percentage of voting shares held by such persons in excess of 25% shall be forfeited, including any cumulative dividend. However, CN's Articles provide that in the event that the 25% limit is exceeded solely as a result of a redemption, purchase for cancellation or other acquisition of common shares by CN, the only consequence to the relevant shareholder is that the shareholder is not entitled to exercise the voting rights attached to the common shares held by such shareholder that are in excess of the 25% limit.

CN's Articles confer on the Board of Directors all powers necessary to give effect to the share ownership constraint, including the ability to pay dividends or to make other distributions which would otherwise be prohibited if the event giving rise to the prohibition was inadvertent or of a technical nature or it would otherwise be inequitable not to pay the dividends or make the distribution. CN's Articles provide that the Board of Directors may adopt by-laws concerning the administration of the share ownership constraint described above, including by-laws requiring a shareholder to furnish a declaration indicating whether he or she is the beneficial owner of the shares and whether he or she is an associate of any other shareholder.

In addition, CN is authorized to refuse to recognize the ownership rights that would otherwise be attached to any voting shares held, beneficially owned or controlled, directly or indirectly, contrary to the share ownership constraint. Finally, CN has the right, for the purpose of enforcing any share ownership constraint imposed pursuant to its Articles, to sell, as if it were the owner thereof, any voting shares that are owned or that the directors determine may be owned, by any person or persons contrary to such share ownership constraint.

**6.3 *RATINGS OF DEBT SECURITIES***

The Company's access to long-term funds in the debt capital markets depends on its credit rating and market conditions. The Company believes that it continues to have access to the long-term debt capital markets. Rating downgrades could limit the Company's access to the credit markets, or increase its borrowing costs. Various classes of CN's outstanding securities have been rated by several rating organizations, as described in detail below, as of the date hereof.

---

| | | | |
|:---|:---|:---|:---|
| | **DBRS Morningstar** | **Moody's Investors Service** | **S&P Global Ratings<br> Canada** |
| **Long-Term Debt** | A | A2 | A- |
| **Commercial Paper** | R-1 (low) | P-1 | A-2 |

---

These ratings are given the following credit characteristics by the various rating agencies:

***DBRS Morningstar (DBRS)***

&nbsp;&nbsp;&nbsp;&nbsp;*·* Long-term debt rated A is of
 good credit quality. The capacity for the payment of financial obligations is substantial,
 but of lesser quality than AA. May be vulnerable to future events, but qualifying negative

#### 19
*2025 Annual Information Form*

---

| | |
|:---|:---|
|  | factors are considered manageable. This rating falls within the third highest of DBRS's ten long-term debt rating categories which range from "AAA" to "D". |
| · | Commercial paper rated R-1 (low) is of good credit quality. The capacity for the payment of short-term financial obligations as they fall due is substantial. Overall strength is not as favourable as higher rating categories. May be vulnerable to future events, but qualifying negative factors are considered manageable. This rating falls within the third highest of DBRS's ten short-term debt rating categories which range from "R-1 (high)" to "D". |

---

***Moody's Investors Service (Moody's)***

· Long-term debt obligations rated A are
 judged to be upper-medium grade and are subject to low credit risk. This rating falls within
 the third highest of Moodys' nine generic long-term obligation rating categories which range
 from "Aaa" to "C". The modifier "2" indicates a ranking
 in the mid-range of that generic rating category.

· Commercial paper rated P-1 indicates that
 CN has a superior ability to repay short-term debt obligations. This rating falls within
 the highest of Moodys' four generic short-term debt-rating categories, which range from "P-1"
 to "NP".

***S&P Global Ratings Canada (S&P)***

· Long-term debt obligations rated A are
 somewhat more susceptible to the adverse effects of changes in circumstances and economic
 conditions than obligations in higher rated categories. However, the obligor's capacity
 to meet its financial commitment on the obligations is still strong. This rating falls within
 the third highest of S&P's ten major long-term credit rating categories which range
 from "AAA" to "D". The modifier "-" indicates a ranking
 in the low-range of that generic rating category.

· A short-term obligation rated A-2 is rated
 in the second highest category by S&P, which ranges from "A-1" to "D".
 The obligor's capacity to meet its financial commitment on the obligation is satisfactory,
 but somewhat more susceptible to the adverse effects of changes in circumstances and economic
 conditions.

The ratings of CN's securities described above should not be construed as a recommendation to buy, sell, or hold CN securities and do not address the market price or suitability of a specific security for a particular investor. Ratings may be revised or withdrawn at any time by the rating agencies.

As is common practice, during the last two years, each of the above-noted credit rating agencies charged CN for their rating services, which include annual surveillance fees covering CN's outstanding long-term and short-term debt securities, in addition to one-time rating fees when debt is initially issued. CN reasonably expects that such payments will continue to be made for rating services in the future. CN has not made any payments to any of the above-noted credit rating agencies for any other service during the last two years.

**Exhibit 97**

**CANADIAN NATIONAL RAILWAY COMPANY**

**FINANCIAL STATEMENT COMPENSATION RECOUPMENT POLICY**

This Canadian National Railway Company Compensation Recoupment Policy (the "**Policy**") has been adopted by the Human Resources and Compensation Committee and the Board of Directors of Canadian National Railway Company (the "**Company**") at their meetings held respectively on October 23 and 24, 2023. This Policy provides for the recoupment of certain executive compensation in the event of an accounting restatement resulting from material noncompliance with financial reporting requirements under U.S. federal securities laws in accordance with the terms and conditions set forth herein. This Policy is intended to comply with the requirements of Section 10D of the Exchange Act (as defined below) and Section 303A.14 of the NYSE Listed Company Manual.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>Definitions</u>. For the purposes of this Policy, the following terms shall have the meanings set forth below. Capitalized terms used but not defined in this Policy shall have the meanings set forth in the 1996 Management Long-Term Incentive Plan (as may be amended from time to time).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) "**Committee**" means the Human Resources and Compensation Committee of the Board of Directors ("the **Board**") or any successor committee thereof. If there is no Human Resources and Compensation Committee of the Board, references herein to the Committee shall refer to the Company's committee of independent directors that is responsible for executive compensation decisions, or in the absence of such a compensation committee, the independent members of the Board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) "**Covered Compensation**" means any Incentive-based Compensation "received" by a Covered Executive during the applicable Recoupment Period; *provided* that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) such Covered Compensation was received by such Covered Executive (A) after the Effective Date, (B) after he or she commenced service as an Executive Officer and (C) while the Company had a class of securities publicly listed on a United States national securities exchange; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii) such Covered Executive served as an Executive Officer at any time during the performance period applicable to such Incentive-based Compensation.

For purposes of this Policy, Incentive-based Compensation is "**received**" by a Covered Executive during the fiscal period in which the Financial Reporting Measure applicable to such Incentive-based Compensation (or portion thereof) is attained, even if the payment or grant of such Incentive-based Compensation is made thereafter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) "**Covered Executive**" means any current or former Executive Officer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) "**Effective Date**" means October 2, 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) "**Exchange Act**" means the U.S. Securities Exchange Act of 1934, as amended.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) "**Executive Officer**" of the Company means executives holding the position of Senior Vice-President or more senior positions at the Company, as well as the Vice-President and Corporate Comptroller of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) "**Financial Reporting Measure**" means any (i) measure that is determined and presented in accordance with the accounting principles used in preparing the Company's financial statements, (ii) stock price measure or (iii) total shareholder return measure (and any measures that are derived wholly or in part from any measure referenced in clause (i), (ii) or (iii) above). For the avoidance of doubt, any such measure does not need to be presented within the Company's financial statements or included in a filing with the U.S. Securities and Exchange Commission to constitute a Financial Reporting Measure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) "**Financial Restatement**" means a restatement of the Company's financial statements due to the Company's material noncompliance with any financial reporting requirement under U.S. federal securities laws that

is required in order to correct:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i) an error in previously issued financial statements that is material to the previously issued financial statements; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) an error that would result in a material misstatement if the error were (A) corrected in the current period or (B) left uncorrected in the current period.

For purposes of this Policy, a Financial Restatement shall not be deemed to occur in the event of a revision of the Company's financial statements due to an out-of-period adjustment (i.e., when the error is immaterial to the previously issued financial statements and the correction of the error is also immaterial to the current period) or a retrospective (1) application of a change in accounting principles; (2) revision to reportable segment information due to a change in the structure of the Company's internal organization; (3) reclassification due to a discontinued operation; (4) application of a change in reporting entity, such as from a reorganization of entities under common control; or (5) revision for stock splits, reverse stock splits, stock dividends or other changes in capital structure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) "**Incentive-based Compensation"** means any compensation (including, for the avoidance of doubt, any cash or equity or equity-based compensation, whether deferred or current) that is granted, earned and/or vested based wholly or in part upon the achievement of a Financial Reporting Measure. For purposes of this Policy, "Incentive-based Compensation" shall also be deemed to include any amounts which were determined based on (or were otherwise calculated by reference to) Incentive-based Compensation (including, without limitation, any amounts under any long-term disability, life insurance or supplemental retirement or severance plan or agreement or any notional account that is based on Incentive-based Compensation, as well as any earnings accrued thereon).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) "**NYSE**" means the New York Stock Exchange, or any successor thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) "**Recoupment Period**" means the three fiscal years completed immediately preceding the date of any applicable Recoupment Trigger Date. Notwithstanding the foregoing, the Recoupment Period additionally includes any transition period (that results from a change in the Company's fiscal year) within or immediately following those three completed fiscal years, provided that a transition period between the last day of the Company's previous fiscal year end and the first day of its new fiscal year that comprises a period of nine (9) to twelve (12) months would be deemed a completed fiscal year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) "**Recoupment Trigger Date**" means the earlier of (i) the date that the Board (or a committee thereof or the officer(s) of the Company authorized to take such action if Board action is not required) concludes, or reasonably should have concluded, that the Company is required to prepare a Financial Restatement, and (ii) the date on which a court, regulator or other legally authorized body directs the Company to prepare a Financial Restatement.

&nbsp;&nbsp;&nbsp;&nbsp;2. <u>Recoupment of Erroneously Awarded Compensation</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In the event of a Financial Restatement, if the amount of any Covered Compensation received by a Covered Executive (the "**Awarded Compensation**") exceeds the amount of such Covered Compensation that would have otherwise been received by such Covered Executive if calculated based on the Financial Restatement (the "**Adjusted Compensation**"), the Company shall reasonably promptly recover from such Covered Executive an amount equal to the excess of the Awarded Compensation over the Adjusted Compensation, each calculated on a pre-tax basis (such excess amount, the "**Erroneously Awarded Compensation**").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) If (i) the Financial Reporting Measure applicable to the relevant Covered Compensation is stock price or total shareholder return (or any measure derived wholly or in part from either of such measures) and (ii) the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in the Financial Restatement, then the amount of Erroneously Awarded Compensation shall be determined (on a pre-tax basis) based on the Company's reasonable estimate of the effect of the Financial Restatement on the Company's stock price or total shareholder return (or the derivative measure thereof) upon which such Covered Compensation was received.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) For the avoidance of doubt, the Company's obligation to recover Erroneously Awarded Compensation is not dependent on (i) if or when the restated financial statements are filed or (ii) any fault of any Covered Executive for the accounting errors or other actions leading to a Financial Restatement.<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Notwithstanding anything to the contrary in Sections 2‎(a) through ‎(c) hereof, the Company shall not be required to recover any Erroneously Awarded Compensation if both (x) the conditions set forth in either of the following clauses (i), (ii), or (iii) are satisfied and (y) the Committee (or a majority of the independent directors serving on the Board) has determined that recovery of the Erroneously Awarded Compensation would be impracticable:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the direct expense paid to a third party to assist in enforcing the recovery of the Erroneously Awarded Compensation under this Policy would exceed the amount of such Erroneously Awarded Compensation to be recovered; *provided* that, before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation pursuant to this Section 2‎(d), the Company shall have first made a reasonable attempt to recover such Erroneously Awarded Compensation, document such reasonable attempt(s) to make such recovery and provide that documentation to the NYSE;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) recovery of the Erroneously Awarded Compensation would violate the laws of Canada and the Province of Québec to the extent such law was adopted prior to November 28, 2022 (*provided* that, before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation pursuant to this Section 2(d)), the Company shall have first obtained an opinion of home country counsel of Canada and the Province of Québec, that is acceptable to the NYSE, that recovery would result in such a violation, and the Company must provide such opinion to the NYSE; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) recovery of the Erroneously Awarded Compensation would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of Sections 401(a)(13) or 411(a) of the U.S. Internal Revenue Code of 1986, as amended (the "**Code**").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Company shall not indemnify any Covered Executive, directly or indirectly, for any losses that such Covered Executive may incur in connection with the recovery of Erroneously Awarded Compensation pursuant to this Policy, including through the payment of insurance premiums or gross-up payments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) The Committee shall determine, in its sole discretion, the manner and timing in which any Erroneously Awarded Compensation shall be recovered from a Covered Executive in accordance with applicable law, including, without limitation, by (i) requiring reimbursement of Covered Compensation previously paid in cash; (ii) seeking recovery of any gain realized on the vesting, exercise, settlement, sale, transfer or other disposition of any equity or equity-based awards; (iii) offsetting the Erroneously Awarded Compensation amount from any compensation otherwise owed by the Company or any of its affiliates to the Covered Executive; (iv) cancelling outstanding vested or unvested equity or equity-based awards; and/or (v) taking any other remedial and recovery action permitted by applicable law. For the avoidance of doubt, except as set forth in Section 2(d), in no event may the Company accept an amount that is less than the amount of Erroneously Awarded Compensation; *provided* that, to the extent necessary to avoid any adverse tax consequences to the Covered Executive pursuant to Section 409A of the Code, any offsets against amounts under any nonqualified deferred compensation plans (as defined under Section 409A of the Code) shall be made in compliance with Section 409A of the Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>Administration</u>. This Policy shall be administered by the Committee. All decisions of the Committee shall be final, conclusive and binding upon the Company and the Covered Executives, their beneficiaries, executors, administrators and any other legal representative. The Committee shall have full power and authority to (i) administer and interpret this Policy; (ii) correct any defect, supply any omission and reconcile any inconsistency in this Policy; and (iii) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of this Policy and to comply with applicable law (including Section 10D of the Exchange Act) and applicable stock market or exchange rules and regulations. Notwithstanding anything to the contrary contained herein, to the extent permitted by Section 10D of the Exchange Act and Section 303A.14 of the NYSE Listed

Company Manual, the Board may, in its sole discretion, at any time and from time to time, administer this Policy in the same manner as the Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <u>Amendment/Termination</u>. Subject to Section 10D of the Exchange Act and Section 303A.14 of the NYSE Listed Company Manual, this Policy may be amended or terminated by the Committee at any time. To the extent that any applicable law, or stock market or exchange rules or regulations require recovery of Erroneously Awarded Compensation in circumstances in addition to those specified herein, nothing in this Policy shall be deemed to limit or restrict the right or obligation of the Company to recover Erroneously Awarded Compensation to the fullest extent required by such applicable law, stock market or exchange rules and regulations. Unless otherwise required by applicable law, this Policy shall no longer be effective from and after the date that the Company no longer has a class of securities publicly listed on a United States national securities exchange.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. <u>Interpretation</u>. Notwithstanding anything to the contrary herein, this Policy is intended to comply with the requirements of Section 10D of the Exchange Act and Section 303A.14 of the NYSE Listed Company Manual (and any applicable regulations, administrative interpretations or stock market or exchange rules and regulations adopted in connection therewith). The provisions of this Policy shall be interpreted in a manner that satisfies such requirements and this Policy shall be operated accordingly. If any provision of this Policy would otherwise frustrate or conflict with this intent, the provision shall be interpreted and deemed amended so as to avoid such conflict.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. <u>Other Compensation Clawback/Recoupment Rights</u>. Any right of recoupment under this Policy is in addition to, and not in lieu of, any other remedies, rights or requirements with respect to the clawback or recoupment of any compensation that may be available to the Company pursuant to the terms of any other recoupment or clawback policy of the Company (or any of its affiliates) that may be in effect from time to time, any provisions in any employment agreement, offer letter, equity plan, equity award agreement or similar plan or agreement, and any other legal remedies available to the Company, as well as applicable law, stock market or exchange rules, listing standards or regulations; *provided*, *however*, that any amounts recouped or clawed back under any other policy that would be recoupable under this Policy shall count toward any required clawback or recoupment under this Policy and vice versa.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Exempt Compensation</u>. Notwithstanding anything to the contrary herein, the Company has no obligation to seek recoupment of amounts paid to a Covered Executive which are granted, vested or earned based solely upon the occurrence or non-occurrence of nonfinancial events. Such exempt compensation includes, without limitation, base salary, time-vesting awards, compensation awarded on the basis of the achievement of metrics that are not Financial Reporting Measures or compensation awarded solely at the discretion of the Committee or the Board, *provided* that such amounts are in no way contingent on, and were not in any way granted on the basis of, the achievement of any Financial Reporting Measure performance goal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 8. <u>Miscellaneous</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Any applicable award agreement or other document setting forth the terms and conditions of any compensation covered by this Policy shall be deemed to include the restrictions imposed herein and incorporate this Policy by reference and, in the event of any inconsistency, the terms of this Policy will govern. For the avoidance of doubt, this Policy applies to all compensation that is received on or after the Effective Date, regardless of the date on which the award agreement or other document setting forth the terms and conditions of the Covered Executive's compensation became effective, including, without limitation, compensation received under the 1996 Management Long-Term Incentive Plan and any successor plan thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) This Policy shall be binding and enforceable against all Covered Executives and their beneficiaries, heirs, executors, administrators or other legal representatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) All issues concerning the construction, validity, enforcement and interpretation of this Policy and all related documents, including, without limitation, any employment agreement, offer letter, equity award agreement or similar agreement, shall be governed by, and construed in accordance with, the laws of Canada and the Province of Québec, without giving effect to any choice of law or conflict of law rules or provisions (whether of Canada and the Province of Québec or any other jurisdiction) that would cause the application of the laws of any jurisdiction other

than Canada and the Province of Québec.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Covered Executives, their beneficiaries, executors, administrators and any other legal representative and the Company shall initially attempt to resolve all claims, disputes or controversies arising under, out of or in connection with this Policy by conducting good faith negotiations amongst themselves. Any and all disputes, claims or causes of action arising from or relating to the enforcement, performance or interpretation of this Policy shall be brought in any state or federal court of competent jurisdiction in the State of Illinois, City of Chicago or in any federal or provincial courts of the Province of Quebec. The Covered Executives, their beneficiaries, executors, administrators and any other legal representative and the Company, shall not commence any suit, action or other proceeding arising out of or based upon this Agreement except in such courts, and hereby waive, and agree not to assert, by way of motion, as a defense or otherwise, in any such suit, action or proceeding, any claim that such party is not subject to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Policy or the subject matter hereof may not be enforced in or by such courts. To the fullest extent permitted by law, the Covered Executives, their beneficiaries, executors, administrators, and any other legal representative, and the Company, shall waive (and shall hereby be deemed to have waived) the right to resolve any such dispute through a trial by jury.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) If any provision of this Policy is determined to be unenforceable or invalid under any applicable law, such provision will be applied to the maximum extent permitted by applicable law and shall automatically be deemed amended in a manner consistent with its objectives to the extent necessary to conform to any limitations required under applicable law.
