IDENTIFICATION OF THE AUDIT COMMITTEE
On December 31, 2024, Stantec’s Audit and Risk Committee was made up of the following four members: Shelley A. M. Brown (Chair), Angeline G. Chen, Donald J. Lowry, and Celina J. Wang Doka. On January 1, 2025, Rick Eng and Christopher F. Lopez joined the Audit and Risk Committee, and on January 31, 2025, Donald J. Lowry retired from Stantec's Board of Directors and the Audit and Risk Committee, which is currently made up of five members.
AUDIT COMMITTEE FINANCIAL EXPERT
As of December 31, 2024, the following Audit and Risk Committee members were identified as audit committee financial experts (as such term is defined in the rules and regulations of the Securities Exchange Commission): Shelley A. M. Brown, Donald J. Lowry, and Celina J. Wang Doka. Rick Eng and Christopher F. Lopez joined the Audit and Risk Committee on January 1, 2025 and are both audit committee financial experts. The Securities and Exchange Commission has indicated that the designation of a person as an audit committee financial expert does not 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 of Directors 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 of Directors. All current members of Stantec's Audit and Risk Committee - Shelley A. M. Brown, Angeline G. Chen, Rick Eng, Christopher F. Lopez , and Celina J. Wang Doka - are independent, as that term is defined by the New York Stock Exchange’s corporate governance standards applicable to Stantec. Prior to his retirement from the Audit and Risk Committee, Donald J. Lowry was also independent.
CODE OF ETHICS
Stantec has adopted a code of ethics, entitled the Stantec Code of Business Conduct (the “Code”). The Code applies to all directors, officers and employees of Stantec, including Stantec’s principal executive officer, principal financial officer and principal accounting officer. Stantec requires that all officers and employees annually certify that they have read and understand the Code. The Code is reviewed regularly to ensure that it complies with all legal requirements and is in alignment with best practices. In the event that amendments are needed, recommendations are made to the Board of Directors for approval. No amendments nor waivers from any provision of the Code were made nor granted during Stantec's most recently completed fiscal year. The Code is available on Stantec’s website (stantec.com) under the “About – Corporate Governance” section.
The Board of Directors believes that providing a forum for employees and officers to raise concerns about ethical conduct and treating all complaints with the appropriate level of seriousness fosters a culture of ethical conduct within Stantec. The Code sets out our procedures for reporting and investigating observations or concerns raised by employees or officers of the company. Stantec monitors compliance with the Code through its external integrity hotline. The integrity hotline hosted by an independent third party allows officers or employees to report concerns regarding breaches of the Code in writing, over the telephone, by mail or by email. All complaints are treated as confidential, and requests to maintain anonymity are respected to the extent possible. The integrity hotline is managed by an independent third party.
Copies of all complaints are reviewed by the chair of the Audit and Risk Committee upon receipt. A quarterly report is presented to the Audit and Risk Committee and the Sustainability and Safety Committee summarizing the status of any active investigations of complaints and the resolution of all complaints made through the integrity hotline.

The Board of Directors believes that its effectiveness is furthered when directors exercise independent judgment in considering transactions and agreements. As such, if at any Board of Directors’ meeting a director or executive officer has a material interest in a matter being considered, such director or officer would not be present for discussions relating to the matter and would not participate in any vote on the matter.
