Evaluation of Disclosure Controls and Procedures

As at March 31, 2025, an evaluation was carried out under the supervision of and with the participation of the Company's management, including its CEO and CFO, of the effectiveness of the design and operation of the Company's disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on that evaluation, the CEO and CFO concluded that these disclosure controls and procedures were effective as at March 31, 2025, to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified by the SEC rules and forms and (ii) accumulated and communicated to the Company’s management, including the CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

Part II

For further details refer to Item 1. Financial Statements, Note 13 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 U.S. Environmental Protection Agency ("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.
