INCORPORATED DOCUMENTS

Annual Information Form

The Company’s Annual Information Form (“AIF”) is filed as Exhibit 99.1 to this Annual Report.

Management’s Discussion and Analysis

The Company’s management’s discussion and analysis (“MD&A”) is filed as Exhibit 99.2 to this Annual Report.

Audited Annual Financial Statements

The Company’s audited consolidated financial statements and the notes thereto (the “Annual Financial Statements”) are filed as Exhibit 99.3 to this Annual Report.

DISCLOSURE CONTROLS AND PROCEDURES

At the end of the period covered by this report, an evaluation was carried out under the supervision of and with the participation of the Company’s management, including the President and Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a - 15(e) and Rule 15d - 15(e) under the United States Securities Exchange Act (the “Exchange Act”)). Based on that evaluation, the CEO and the CFO have concluded that as of the end of the period covered by this report, the Company’s disclosure controls and procedures were adequately designed and effective in ensuring that: (i) information required to be disclosed by the Company in reports that it files or submits to the Commission under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms and (ii) information required to be disclosed in the Company’s reports filed under the Exchange Act is accumulated and communicated to management, including the CEO and CFO, as appropriate, to allow for accurate and timely decisions regarding required disclosure.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. The Company’s internal control over financial reporting process is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes, in accordance with generally accepted accounting principles.

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

Management conducted an evaluation of the design and operation of the Company’s internal controls over financial reporting as of the end of the Company’s last fiscal year, based on the criteria set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation. Based on this evaluation, management, including the CEO and the CFO, has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2025.

ATTESTATION REPORT OF THE REGISTERED PUBLIC ACCOUNTING FIRM

The Company’s auditor has attested to the effectiveness of the Company's internal control over financial reporting as of December 31, 2025. The auditor’s attestation immediately precedes the audited consolidated financial statements of the Company in Exhibit 99.3 and is incorporated by reference in this Annual Report.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

During the period covered by this Annual Report, no change occurred in the Company’s internal control over financial reporting that has materially affected or is reasonably likely to materially affect the Company’s internal control over financial reporting.

The Company’s management, including the CEO and CFO, do not expect that its disclosure controls and procedures or internal controls and procedures will prevent all error and fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, a control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur, and not be detected.
