Sustainability at WSP

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 estimates, plans, strategic ambitions, objectives, expectations, opinions, forecasts, projections, guidance, outlook, 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; achieving over 98% completion rate of the Code of Conduct training (onboarding or refresher)/year; and aiming to grow key markets and services and help 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 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 and reduce our energy consumption; the state of the global economy and the economies of the regions in which the Corporation operates; and sufficiency of internal and external resources, as well as those 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; 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 of our most recent annual management’s discussion and analysis, which is 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 July 14, 2025 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.
