WSP completes acquisition of e2m

Certain information contained in this release 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. Forward-looking statements may include estimates, plans, strategic ambitions, objectives, expectations, opinions, forecasts, projections, guidance, outlook or other statements that are not statements of fact, including references to assumptions.

Forward-looking statements in this release may include, without limitation, statements about the benefits, synergies and opportunities between WSP and e2m; expectations regarding complementarity and compatibility of e2m’s business with WSP’s existing business; other anticipated benefits of the acquisition and their expected impact on WSP’s delivery of its strategic plan and its long-term vision; WSP’s business outlook, objectives, development, plans, integration, growth strategies and other strategic priorities, and WSP’s leadership position in its markets; and statements relating to WSP’s future growth, results of operations, financial performance, business, prospects and opportunities and other statements that are not historical facts.

Forward-looking statements are based on a number of assumptions believed by WSP to be reasonable as at the date hereof, including assumptions set out through this release and including, without limitation, principal assumptions about WSP’s ability to retain and attract new business, achieve synergies and maintain market position arising from successful integration plans relating to the acquisition; WSP’s ability to complete the integration of e2m within anticipated time periods and at expected cost levels; WSP’s ability to attract and retain key employees in connection with the proposed acquisition; management’s expectations in relation to the future performance and economic conditions and other factors in relation to e2m; the realization of the expected strategic, financial and other benefits of the acquisition in the timeframe anticipated; as well as the assumptions underlying the 2025-2027 Global Strategic Action Plan issued on February 12, 2025 and the 2026 financial outlook set out in WSP's press releases dated February 25, 2026, May 6, 2026 and August 5, 2026. If any of these assumptions prove to be inaccurate, WSP’s actual results could differ materially from those expressed or implied in forward-looking statements.

Although WSP believes that the expectations reflected in such forward-looking statements are reasonable, it can give no assurance that such expectations will prove to have been correct. In evaluating these forward-looking statements, investors 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, WSP’s inability to successfully integrate e2m's business; the potential failure to realize anticipated benefits from the acquisition; risks relating to the post-acquisition business; the deterioration of our financial position or net cash position; our working capital requirements; our accounts receivable; our increased indebtedness and raising capital; the impairment of long-lived assets; our foreign currency exposure; our income taxes; as well as other risks detailed from time to time in reports filed by WSP with securities regulators or securities commissions or other documents that WSP makes public, which may cause actual results or events 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 WSP’s MD&A for the fourth quarter and year ended December 31, 2025 and as supplemented by section 17, “Risk Factors” of WSP’s MD&A for the second quarter and the six-month period ended June 26, 2026, 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 in relation to 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 release describe WSP’s expectations as of the date hereof and, accordingly, are subject to change after such date. Except as may be required under Canadian securities laws, WSP does not assume any obligation to publicly update or to revise any forward-looking statements made in this release, whether as a result of new information, future events or otherwise. The forward-looking statements contained in this release are expressly qualified in their entirety by this cautionary statement. WSP may also make oral forward-looking statements from time to time. WSP advises that the above paragraphs and the risk factors set forth in section 20, “Risk factors” of WSP’s MD&A for the fourth quarter and year ended December 31, 2025, and as supplemented by section 17, “Risk Factors” of WSP’s MD&A for the second quarter and the six-month period ended June 26, 2026, should be read for a description of certain factors that could cause the actual results of WSP to differ materially from the results expressed or implied in any oral forward-looking statements. Readers should not place undue reliance on forward-looking statements.
