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 long-term 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 its Biodiversity Statement); becoming a leading brand in the professional services universe; earning 67% of total annualized gross revenues from SDG-Linked Revenues by 2027; reducing its energy consumption and GHG emissions in accordance with established scope 1, 2 and 3 reduction targets; sourcing 100% renewable electricity; decreasing by 150 bps voluntary turnover by 2027; filling 75% of global leadership positions (and those of their direct reports) by internal candidates by 2027; having over 95% of its IT operations achieve ISO 27001 for Information Security Management; achieving over 98% completion rate of the annual Code of Conduct training (onboarding/ or refresher)/year; implementing and continuously evolving its AI governance framework; reaching $200M investments in research and development, innovation and digital by 2027; enhancing its resilience to climate-related risks; managing nature-related risks and opportunities; delivering actions under its TNFD roadmap; aiming to grow key markets and services and helping clients achieve their sustainability ambitions.

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. Forward-looking statements contained in this page for periods beyond 2025 involve longer-term assumptions and estimates than forward-looking statements for 2025 and are consequently subject to greater uncertainty, including, without limitation, assumptions about our ability to develop and implement various corporate and business initiatives, including new procedures, policies and targets to decarbonize our operations and supply chain, reduce our energy consumption and foster a low-carbon culture; the state of the global economy and the economies of the regions in which the Corporation operates; and the sufficiency of internal and external resources, as well as other assumptions described in the “Forward-Looking Statements” section of our latest Global Sustainability Report.

In evaluating these forward-looking statements, readers should specifically consider various risk factors, which, if realized, could cause WSP’s actual results or events to differ materially from those expressed or implied in forward-looking statements. Such risk factors include, but are not limited to, the rising complexity of the geopolitical landscape and macro-economic developments; the failure to maintain our competitive positioning in rapidly changing competitive market; the failure to effectively adopt, integrate, and leverage existing and emerging technologies in our operations; the failure to implement sufficient corporate and business initiatives; challenges associated with the implementation of global systems (including ERP); reliance on third-party data, methodologies and assumptions; difficulties in collecting ESG data (including from acquired companies and external providers such as landlords and suppliers); volatility or constraints in renewable energy markets; availability and cost of carbon credits; physical climate risks affecting operations; ability of suppliers and partners to meet sustainability expectations; difficulty in accurately measuring, evaluating and disclosing our sustainability performance; failure to accurately estimate the sustainability benefits of our project work; negative stakeholder perception or reaction to our sustainability performance or initiatives, as well as other risks detailed in the “Risk Factors” section WSP’s Management’s Discussion and Analysis (MD&A) for the year ended December 31, 2025 and the first quarter ended March 27, 2026, as may be supplemented from time to time, which are available on SEDAR+ at www.sedarplus.ca and which section is incorporated herein by reference into this cautionary statement.

The forward-looking statements contained in this page are made as of May 13, 2026 and WSP 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 except as required under Canadian securities laws. 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.
