Stantec (TSX, NYSE:STN), a global leader in sustainable engineering, architecture and environmental consulting, released its second quarter 2025 results today which were underpinned by the continued demand for Â鶹´«Ã½¡¯s services and solid project execution.

Net revenue increased to $1.6 billion in the second quarter, a 6.9% year-over-year increase, primarily driven by 4.8% organic growth[1]. Organic growth was achieved in each of Â鶹´«Ã½'s regional and business operating units, with Canada, the United States and Global achieving 6.2%, 4.4% and 4.3% organic growth, respectively. Most notably, Water achieved 12.4% organic growth and Energy & Resources delivered 9.5% organic growth. Second quarter 2025 adjusted EBITDA increased 15.0% or $37.1 million, and adjusted EBITDA margin was 17.8%, up 120 basis points compared to the second quarter of 2024. Â鶹´«Ã½ delivered diluted earnings per share (EPS) of $1.19 and adjusted EPS of $1.36.

¡°Throughout the first half of 2025, Â鶹´«Ã½ has delivered strong financial and operational results, underpinned by the diversification of our business, and continued demand across all of our regions,¡± said Gord Johnston, President and CEO. ¡°With our strong performance year-to-date and the acquisitions of Ryan Hanley, Cosgroves, and now Page, we are increasing our guidance for the full year.¡±

[1] Adjusted EPS, adjusted net income, adjusted EBITDA, adjusted EBITDA? margin, and adjusted ROIC are non-IFRS measures, and organic growth, acquisition growth and DSO are other financial measures (discussed in the Definitions section of the Q2 2025 MD&A).

Stantec now expects to achieve net revenue growth of 10% to 12% in 2025, increasing the range from 7% to 10%, due to the acquisitions completed during the second quarter and the closing of the acquisition of Page in July, and supported by the Company's continued expectations to achieve net revenue growth in the mid- to high-single digits. Â鶹´«Ã½'s US organic growth outlook has now moderated slightly to mid-single digits related to slower procurement cycles persisting in the public sector in the near term, and elevated caution in the private sectors particularly for larger projects. The Company continues to expect that Canada¡¯s organic net revenue growth to be in the mid- to high-single digits, driven by continuing strong momentum and elevated backlog levels. Â鶹´«Ã½ also continues to expect organic net revenue growth in Global in the mid to high single-digits, driven by continued high levels of activity in the Water business under the ongoing UK Asset Management Program (AMP) and framework agreements and positive demand fundamentals in the Energy & Resources business.

Stantec has increased and narrowed the range for adjusted EBITDA margin slightly to 17.0% to 17.4%, from 16.7% to 17.3%, reflecting strong project margins driven by solid project execution and continued discipline and enhanced strategies in the management of administration and marketing costs. The Company expects adjusted EBITDA margin in Q3 2025 to be near or above the high end of this range because of increased seasonal activities in the northern hemisphere, offset by lower expected margins in Q4 of 2025 due to seasonal effects.

Stantec's effective tax rate is now expected to fall within a range of 23.5% to 24.5%, an increase from 22% to 23%, due to the mix of earnings from the various jurisdictions we operate in and moderating impacts on tax planning strategies.

Overall, Â鶹´«Ã½ continues to expect to drive adjusted net income to a margin of greater than 8.8% of net revenue; however, the Company now expects to deliver 18.5% to 21.5% growth in adjusted EPS in comparison to 2024, increased from 16% to 19% in its previous guidance, and adjusted ROIC greater than 12.5%.

The above targets do not include any assumptions for additional acquisitions beyond those noted in this Outlook section or further impact from significant share price movements subsequent to June 30, 2025, and the relative total shareholder return components on our share-based compensation programs.
