Certain information contained in this page is not based on historical or current facts and may constitute forward-looking statements or forward-looking information (collectively, “forward-looking statements”) under Canadian securities laws. These forward-looking statements relate to future events or future performance and may include, but are not limited to, estimates, plans, strategic ambitions, objectives, expectations, opinions, forecasts, projections, guidance, outlook or other statements that are not statements of fact, including references to assumptions, and reflect the expectations of management of the Corporation regarding, without limitation, its sustainability ambitions and targets, which include, without limitation, its objectives for measuring and disclosing its sustainability performance (including the objectives and targets described in its 2025-2027 Global Strategic Action Plan, latest Climate and Nature Transition Plan, Sustainability Statement and Biodiversity Statement); reducing its energy consumption, waste, water usage and GHG emissions in accordance with established scope 1, 2 and 3 reduction targets; understanding GHG emissions associated with its designs and advice, and collaborating with clients/partners to drive reductions; and achieving net zero across its value chain by 2040.

Forward-looking statements, by their very nature, are subject to inherent risks and uncertainties and are based on several assumptions, both general and specific, which give rise to the possibility that actual results or events could differ materially from the expectations expressed in or implied by such forward-looking statements and that the business outlook, objectives, plans and strategic priorities may not be achieved. Such assumptions are set out in the “Forward-Looking Statements” section of our latest Global Sustainability Report, which is available on our website at www.wsp.com and which section is incorporated herein by reference. If any of these assumptions prove to be inaccurate, the Corporation’s actual results or events could differ materially from those expressed or implied in forward-looking statements.

In evaluating these forward-looking statements, readers should specifically consider various risk factors, which, if realized, could cause the Corporation's actual results or events to differ materially from those expressed or implied in forward-looking statements, including the risk factors discussed in greater detail in section 20, “Risk Factors” of WSP’s Management Discussion and Analysis (“MD&A”) for the fourth quarter and year ended December 31, 2025 and as supplemented by section 17, “Risk Factors” of our MD&A for the first quarter ended March 27, 2026, and as may be supplemented from time to time in reports filed by the Corporation with securities regulators or securities commissions or other documents that the Corporation makes public, which are available on SEDAR+ at www.sedarplus.ca and which sections are incorporated herein by reference.

Actual results and events may be significantly different from what we currently expect because of the risks associated with our business, industry and global economy and of the assumptions made about these risks. As such, there can be no assurance that actual results will be consistent with forward-looking statements.

The forward-looking statements contained in this page describe the Corporation’s expectations as at July 27, 2026 and, accordingly, are subject to change after such date. Except as required under Canadian securities laws, the Corporation does not assume any obligation to publicly update or to revise any forward-looking statements made in this page or otherwise, whether as a result of new information, future events or otherwise. The forward-looking statements contained in this page are expressly qualified in their entirety by this cautionary statement. Readers should not place undue reliance on forward-looking statements.
