Shareholders may attend the Meeting in person or via live webcast. The Corporation views the use of technology-enhanced shareholder communications as a method to facilitate individual investor participation, making the Meeting more accessible and engaging for all involved by permitting a broader base of Shareholders to participate in the Meeting. All Shareholders will be able to attend, participate, submit questions and vote at the Meeting either in person, or by logging in online and following the instructions set forth in the management information circular of the Corporation dated March 20, 2026 (the "Circular") under the section "General Proxy Matters - How to attend the Meeting".

NOTICE-AND-ACCESS

As permitted by Canadian securities regulators, the Corporation has decided to use the "notice-and-access" mechanism for delivery to both registered and non-registered Shareholders of the Circular prepared in connection with the Meeting and other proxy-related materials (the "Meeting Materials") as well as the annual audited consolidated financial statements of the Corporation for the financial year ended December 31, 2025, together with the independent auditor's report thereon, and related management's discussion and analysis (together, the "Financial Statements"). Notice-and-access is a set of rules that allows issuers to post electronic versions of proxy-related materials online, via SEDAR+ and one other website, rather than mailing paper copies of such materials to Shareholders.

NOTICE OF MEETING

WSP GLOBAL INC.

---

Under notice-and-access, Shareholders still receive in the mail the proxy form or voting instruction form enabling them to vote at the Meeting. However, instead of paper copies of the Meeting Materials and of the Financial Statements, Shareholders receive in the mail a notice which contains information on how they may access the Meeting Materials and the Financial Statements online and how to request paper copies of such documents. The use of notice-and-access will directly benefit the Corporation by substantially reducing our printing and mailing costs, while also being more environmentally responsible through reduced paper use.

In an effort to consciously reduce paper waste, the Corporation strongly encourages its Shareholders to opt for a fully paperless form of communication, including the notice of meeting, proxy voting forms or voting instruction forms. In order to do so, registered Shareholders may contact the Corporation's transfer agent, Computershare Investor Services Inc. ("Computershare"), at 1-800-564-6253 or 1 514-982-7555 and non-registered Shareholders may contact their applicable securities broker holding their Shares. Alternatively, the paperless preference can be requested when submitting a proxy vote through the applicable online platform offered by Computershare for registered Shareholders or Broadridge for non-registered Shareholders. For any further questions or assistance, please contact the Corporation by telephone at 1 438-843-7519 or by email at investors@wsp.com.
