FORWARD-LOOKING STATEMENTS

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, expectations, opinions, forecasts, projections, guidance or other statements that are not statements of fact, 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 concerning measuring and disclosing its sustainability performance (including with respect to the objectives and targets described in its 2025-2027 Global Strategic Action Plan and its Biodiversity Statement); earning 67% of total annualized gross revenues from SDG-Linked Revenues; 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 leadership positions by internal candidates by 2027; having over 95% of its IT operations achieve ISO 27001 for Information Security Management; and achieving over 98% completion rate of the Code of Conduct training (onboarding or refresher)/year.

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 our expectations expressed in, or implied by, such forward-looking statements and that our 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. Such assumptions also include those described in the “Forward-Looking Statements” section of our 2024 Global Sustainability Report. 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 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 continued implementation of our global ERP system; difficulty in accurately measuring, evaluating and disclosing our sustainability performance; our inability to collect environmental, social and governance (“ESG”) data from acquired companies, including for historical years; our inability to collect energy, water, waste and GHG emissions data from external data providers, including landlords, fleet managers and business travel vendors; the unwillingness of suppliers to disclose GHG emissions data and reduce emissions, including for historical years; acquisitions of companies with higher health and safety risk exposure compared to WSP; failure to attract and retain qualified staff to support capturing opportunities associated with the low-carbon transition; failure to accurately estimate the sustainability benefits of our project work; negative stakeholder perception or reaction to our sustainability performance or initiatives; failure to identify climate-related opportunities as well as assess and manage climate-related risks; changes made to regulations that may affect our business and the development of ESG requirement regulations; failure of our internal data systems to track disclosures required by new ESG regulations; failure to retain the services of a qualified external GHG emissions verifier; failure to audit suppliers, as well as other risks detailed from time to time are discussed in greater detail in reports filed by WSP with securities regulators or securities commissions or other documents that WSP makes public, which are available on SEDAR+ at www.sedarplus.ca and may cause events or results to differ materially from the results expressed or implied in any forward-looking statement.

These and other risk factors that could cause actual results or events to differ materially from our expectations expressed in, or implied by, our forward-looking statements are discussed in greater detail in section 20, “Risk Factors” of our management’s discussion and analysis for the fourth quarter and year ended on December 31, 2024, which section is incorporated herein by reference into this cautionary statement.

The forward-looking statements contained in this page describe WSP’s expectations as of the April 30, 2025, and, accordingly, are subject to change after such date. Except as required under Canadian securities legislation, 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. 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.
