DISCLOSURE CONTROLS AND PROCEDURES

The Registrant’s Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the Registrant’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this annual report (the “Evaluation Date”). Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of the Evaluation Date, the Registrant’s disclosure controls and procedures were effective to ensure that information required to be disclosed by the Registrant in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission (the “SEC”) and (ii) accumulated and communicated to the Registrant’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Registrant. 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 generally accepted accounting principles.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of its 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 has excluded eleven entities – Ethos Urban Pty Ltd., Triovest Inc., Astris Infrastructure, LLC, Greystone Sales Group, LLC, Terra Consulting, Higher Ground Consulting, Herold Engineering, Cambium Inc., LRL Associates Ltd., Greenhill Engineers Pty Ltd., RoundShield Partners LLP - acquired by the Company during the last fiscal period from its assessment of internal control over financial reporting as at December 31, 2025. The total assets and total revenues of the eleven majority-owned entities represent 1.7% and 2.3%, respectively of the related consolidated financial statement amounts as at and for the year ended December 31, 2025.

Management has assessed the effectiveness of the Registrant’s internal control over financial reporting as at December 31, 2025, based on the criteria set forth in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management has concluded that, as at December 31, 2025, the Registrant’s internal control over financial reporting was effective.

The effectiveness of the Registrant’s internal control over financial reporting as at December 31, 2025 has been audited by PricewaterhouseCoopers LLP, the Registrant’s independent registered public accounting firm, as stated in their report filed in Exhibit 2 of this Annual Report on Form 40-F.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

During the year ended December 31, 2025, there were no changes in the Registrant’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Registrant’s internal control over financial reporting.

NOTICES PURSUANT TO REGULATION BTR

There were no notices required by Rule 104 of Regulation BTR that the Registrant sent during the year ended December 31, 2025 concerning any equity security subject to a blackout period under Rule 101 of Regulation BTR.

AUDIT COMMITTEE FINANCIAL EXPERTS

The Registrant’s board of directors (the “Board of Directors”) has determined that it has one audit committee financial expert (as such term is defined in the note to paragraph 8(a) of General Instruction B to Form 40-F) serving on its audit & risk committee (the “Audit Committee”). Mr. L. Frederick Sutherland has been determined by the Board of Directors to be an audit committee financial expert and is independent (as such term is defined by the corporate governance standards of the NASDAQ Stock Market (“NASDAQ”) applicable to the Registrant).

Mr. Sutherland was the Executive Vice President and Chief Financial Officer of Aramark Corporation, Philadelphia, PA, a leading global provider of food services, facilities management and uniform and career apparel, from 1997 to 2015. Prior to joining Aramark in 1980, Mr. Sutherland was Vice President, Corporate Banking, at Chase Manhattan Bank, New York, NY. Mr. Sutherland is a director of Consolidated Edison, Inc. and a former director of Sterling Check Corp. Mr. Sutherland is a trustee, executive committee member and audit committee chair of Duke University, and a trustee and financial committee chair of the National Constitution Center. Mr. Sutherland is also a former director and Chair of the Board of WHYY, Philadelphia’s public broadcast affiliate, a former trustee and chair of Episcopal Community Services, a Philadelphia-based anti-poverty agency and a former trustee and chair of People’s Light, a professional non-profit theater. Mr. Sutherland holds an MBA Degree in Finance from the Katz School of the University of Pittsburgh and a Bachelors in Physics and Mathematics from Duke University.

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