2026 Financial Reporting

Over the last few years, management has transformed the business, with the Company becoming a world-class engineering services and nuclear company. This included the substantial completion of two of its three remaining light-rail transit systems legacy LSTK construction contracts and the sale of its remaining 6.76% interest in the shares of Highway 407 ETR, reducing the scale of the LSTK Projects and Capital reportable segments. As such, in order to better reflect this transformation and these achievements, as well as the relative size of the Linxon business in the Company’s consolidated results, AtkinsRéalis has, effective January 1, 2026 and commencing with its first quarter of 2026 financial reports, combined its Linxon, LSTK Projects and Capital operating segments into a single reportable segment referred to as “All other segments”. The reportable segments of the Company that are part of the Engineering Services Regions and the Nuclear segment will remain unchanged. At the same time, taking into account the fact that the Capital segment will no longer be presented on a stand-alone basis, the Company will cease to report financial information separately from Capital and from Professional Services & Project Management (“PS&PM”) activities. Furthermore, the Company will no longer refer to the “AtkinsRéalis Services” line of business, which combines certain activities, further streamlining its financial reporting structure. The Company provides, as additional information, comparative segment results for each quarter of 2025 and for the year ended December 31, 2025 presented under the new segment reporting structure in Section 13.5 of the Company’s 2025 Annual Management’s Discussion and Analysis (the “2025 Annual MD&A”).

Fourth Quarter Financial Results

PS&PM groups together the Company’s segments, namely Engineering Services Regions (Canada, United Kingdom & Ireland (“UKI”), United States & Latin America (“USLA”), and Asia, Middle East & Australia (“AMEA”)), Nuclear, Linxon, and Lump-Sum Turnkey (“LSTK”) Projects, while Capital is its own reportable segment and separate from PS&PM.

Net income attributable to AtkinsRéalis shareholders in the fourth quarter of 2025 was $95.0 million, compared to $52.4 million for the corresponding period in 2024. The increase was mainly due to higher Segment Adjusted EBIT, lower corporate selling, general and administrative expenses and lower net financial expenses, partially offset by higher acquisition-related and integration costs.

2025 – 2027 Financial Targets (Revised)

At its Investor Day held on June 13, 2024, the Company unveiled its 2025 – 2027 Delivering Excellence, Driving Growth strategy, and at the same time provided certain financial targets for 2025 through 2027.

As a result of the strong financial and operating performance of the Nuclear segment during 2025, the significant increase in the Nuclear backlog and the Company’s positive outlook regarding the global demand for the services offered by the Nuclear segment in the mid- and long-term, the Company is raising its Nuclear annual revenue target to between $2.6 billion and $3.0 billion by 2027, from the previous range of between $2.2 billion and $2.5 billion by 2027. The Company is also adjusting its Nuclear Segment Adjusted EBIT to segment revenue ratio target to between 11% and 13%, from the previous range of between 12% and 14%, reflective of the expected business mix.

Also, as a result of a lower than expected organic revenue growth of the Engineering Services Regions business in 2025, partially offset by the backlog increase and the continued strong global demand for the Company’s capabilities for engineering services, the Company is adjusting its Engineering Services Regions organic revenue growth⁽²⁾⁽³⁾ CAGR 2025-2027 to between 5% and 7%, from the previous >8%.

All other financial targets for 2025 – 2027, as announced on June 13, 2024, and as updated on May 15, 2025 are maintained.

Quarterly Dividend

The Board of Directors today declared a cash dividend of $0.02 per share, unchanged from the previous quarter. The dividend is payable on March 27, 2026 to shareholders of record on March 13, 2026. This dividend is an “eligible dividend” for Canadian federal and provincial income tax purposes.

Non-IFRS Financial Measures and Ratios, Supplementary Financial Measures, Total of Segments Measures and Non-Financial Information

The Company reports its financial results in accordance with IFRS® Accounting Standards (“IFRS”). However, the following non‑IFRS financial measures and ratios, supplementary financial measures, total of segments measures and non-financial information are used by the Company in this press release: Organic revenue growth (contraction), EBITDA, Adjusted EBITDA, Segment Adjusted EBITDA, Adjusted net income (loss) attributable to AtkinsRéalis shareholders, Adjusted diluted EPS, Segment Adjusted EBITDA to segment net revenue ratio, Adjusted EBITDA from PS&PM to PS&PM revenue ratio and Segment net revenue, as well as certain measures for various reportable segments that are grouped together, such as Revenue, Segment Adjusted EBIT and Backlog for the various Engineering Services Regions segments and the various segments that comprise the AtkinsRéalis Services line of business. Additional details for these non-IFRS financial measures and ratios, supplementary financial measures, total of segments measures and non-financial information can be found below and in Sections 4 and 13 of the 2025 Annual MD&A, which sections are incorporated by reference into this press release, filed with the securities regulatory authorities in Canada, available on SEDAR+ at www.sedarplus.com and on the Company’s website at www.atkinsrealis.com under the “Investors” section.

Non-IFRS financial measures and ratios, supplementary financial measures, total of segments measures and non-financial information do not have any standardized meaning under IFRS and other issuers may define these measures differently and, accordingly, they may not be comparable to similar measures prepared by other issuers. Such non-IFRS financial measures and ratios, supplementary financial measures, total of segments measures and non-financial information have limitations and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

However, management believes that, in addition to conventional measures prepared in accordance with IFRS, these non-IFRS financial measures and ratios, supplementary financial measures, total of segments measures and non-financial information provide additional insight into the Company’s operating performance and financial position, and certain investors may use this information to evaluate the Company’s performance from period to period. Furthermore, certain non-IFRS financial measures and ratios, certain additional IFRS measures and ratios, certain supplementary financial measures, certain total of segments measures and other non-financial information are presented separately for PS&PM, by excluding components related to Capital, as the Company believes that such measures are useful as these PS&PM activities are usually analyzed separately by the Company. Reconciliations and calculations of non-IFRS measures and ratios, supplementary financial measures, total of segments measures and non-financial information to the most comparable IFRS measures and ratios are set forth below in the section “Reconciliations and Calculations” of this press release.

⁽¹⁾ Total of segments measure.

See “Calculation of organic revenue growth (contraction)” in the section “Reconciliations and Calculations” of this press release for each non-IFRS financial measure used as a component of this non-IFRS ratio.

⁽⁴⁾ Segment Adjusted EBITDA to segment net revenue ratio for Engineering Services Regions and Nuclear are non-IFRS ratio based on Segment Adjusted EBITDA and segment net revenue, both of which are non-IFRS financial measures. See “Calculation of Segment net revenue and Segment Adjusted EBITDA to segment net revenue ratio for Engineering Services Regions and Nuclear” in the section “Reconciliations and Calculations” of this press release for each non-IFRS financial measure used as a component of this non-IFRS ratio.

⁽⁵⁾ Adjusted diluted EPS is a non-IFRS ratio based on adjusted net income (loss) attributable to AtkinsRéalis shareholders, itself a non-IFRS financial measure. See “Reconciliation of Adjusted net income attributable to AtkinsRéalis shareholders from PS&PM to IFRS net income attributable to AtkinsRéalis shareholders” in the section “Reconciliations and Calculations” of this press release for each non-IFRS financial measure used as a component of this non-IFRS ratio.

⁽⁶⁾ Adjusted EBITDA from PS&PM to PS&PM revenue ratio is a non-IFRS ratio based on Adjusted EBITDA from PS&PM and revenue from PS&PM, of which the Adjusted EBITDA from PS&PM is a non-IFRS financial measure. See “Reconciliation of EBITDA and Adjusted EBITDA to IFRS net income and calculation of Adjusted EBITDA to revenue ratio” in the section “Reconciliations and Calculations” of this press release for the non-IFRS financial measure used as a component of this non-IFRS ratio.
