DISCLOSURE CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time period specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. As of March 31, 2023, our Chief Executive Officer and Chief Financial Officer carried out an evaluation with the participation of management of the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of March 31, 2023.

MANAGEMENT’S ANNUAL REPORT ON
INTERNAL CONTROL OVER FINANCIAL REPORTING

Management, including the CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. The Company’s management has employed a framework consistent with Exchange Act Rule 13a-15(c), to evaluate the Company’s internal control over financial reporting described below. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS.

A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, that accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with applicable IFRS, and that receipts and expenditures of the company are only being made in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of

the Company’s assets that could have a material effect on the financial statements. It should be noted that a control system, no matter how well designed or operated, can provide only reasonable assurance, not absolute assurance of achieving the desired control objectives. These inherent limitations include, among other items: (i) that management’s assumptions and judgments could ultimately prove to be incorrect under varying conditions and circumstances; (ii) the impact of any undetected errors; and (iii) that controls may be circumvented by the unauthorized acts of individuals, by collusion of two or more people, or by management override. 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. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that any design will not succeed in achieving its stated goals under all potential future conditions. Accordingly, because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

The Company’s management, including the CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting, and used the framework consistent with that issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013) (COSO) to evaluate the effectiveness of our controls. Based on this evaluation, management concluded that the Company’s internal controls over financial reporting were effective as of March 31, 2023.

ATTESTATION REPORT OF THE REGISTERED PUBLIC ACCOUNTING FIRM

As an "emerging growth company" under the Jumpstart our Business Startups Act, the Company is exempt from Section 404(b) of the Sarbanes-Oxley Act of 2002, which requires that a public company's registered public accounting firm provide an attestation report relating to management' assessment of internal control over financial reporting.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

During the fiscal quarter ended September 30, 2022, there was a material change to the Company’s internal controls over financial reporting, as the Company spun out its Clinics business and related systems into a separate public entity. The Company continues to evaluate its revised control environment, including the transfer of processes related to revenue, leases, property, equipment and other aspects of the Clinics business included in the spinout. The Company has reviewed its internal controls including an assessment of the necessary and appropriate processes and controls with a view to ensuring that the design and operation of the Company’s remaining applicable controls remains effective over financial reporting.

Except as described above, there have been no further changes in the Company’s internal control over financial reporting that occurred that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

NOTICES PURSUANT TO REGULATION BTR

The Company was not required by Rule 104 of Regulation BTR to send any notices to any of its directors or executive officers during the fiscal year ended March 31, 2023.

AUDIT COMMITTEE FINANCIAL EXPERT

The Company’s Board of Directors (the “Board”) has determined that it has at least one audit committee financial expert serving on its Audit Committee. The Board has determined that Helen Boudreau is an audit committee financial expert and is independent, as that term is defined by the Exchange Act and the Nasdaq Global Select Market (“Nasdaq”) corporate governance standards applicable to the Company.

The Commission has indicated that the designation of a person as an audit committee financial expert does not make such person an “expert” for any purpose, impose on such person any duties, obligations or liability that are greater than those imposed on such person as a member of the Audit Committee and the Board in the absence of such designation and does not affect the duties, obligations or liability of any other member of the Audit Committee or Board.

CODE OF ETHICS

The Board has adopted a written code of business conduct and ethics (the “Code”), by which it and all officers and employees of the Company, including the Company’s principal executive officer, principal financial officer and principal accounting officer or controller, abide. There were no waivers granted in respect of the Code during the fiscal year ended March 31, 2023. The Code is posted on the Company’s website at www.reunionneuro.com. If there is an amendment to the Code, or if a waiver of the Code is granted to any of Company’s principal executive officer, principal financial officer, principal accounting officer or controller, the Company intends to disclose any such amendment or waiver by posting such information on the Company’s website. Unless and to the extent specifically referred to herein, the information on the Company’s website shall not be deemed to be incorporated by reference in this Annual Report.
