EDMONTON, Alberta, Aug. 18, 2026 (GLOBE NEWSWIRE) -- TSX, NYSE: STN

Stantec Inc. ("Stantec"), a global leader in sustainable design and engineering, announced today that it has received approval from the Toronto Stock Exchange (the "TSX") respecting an amendment of its previously approved Normal Course Issuer Bid ("NCIB") to increase the maximum number of common shares Stantec may repurchase for cancellation under the NCIB from 2,281,339 (or 2% of Stantec’s issued and outstanding shares as of March 2, 2026), to 5,703,349 common shares (or 5% of Stantec’s shares as of March 2, 2026).

As at August 17, 2026, Stantec had repurchased and cancelled a total of 1,667,292 common shares at a weighted average of $103.43 under the current normal course issuer bid, representing 1.46% of the issued and outstanding common shares as at March 10, 2026, when Stantec filed its initial application with the TSX. The amended NCIB with the higher limit will commence on August 20, 2026 and terminate no later than March 11, 2027. Except for the increase in the maximum number of common shares that may be acquired pursuant to the NCIB, no further amendments have been made to the NCIB. For further details regarding the NCIB, please refer to Stantec’s prior news release dated March 10, 2026.

The automatic share purchase plan (the "ASPP"), implemented in connection with the current NCIB to allow for the purchase of Stantec’s common shares under the NCIB at times when Stantec normally would not be active in the market due to applicable regulatory restrictions or internal trading black-out periods, remains in effect as previously approved by the TSX and will terminate on the earliest of the date on which: (a) the maximum annual purchase limit under the NCIB has been reached; (b) the NCIB expires; or (c) Stantec terminates the ASPP in accordance with its terms. The ASPP constitutes an "automatic securities purchase plan" under applicable Canadian securities laws.

Stantec believes that, from time to time, the market price of its common shares may not adequately reflect the value of its business and its future business prospects. As a result, Stantec believes at such times that its outstanding common shares may represent an attractive investment for Stantec, and an appropriate and desirable use of its available funds. This capital deployment strategy is consistent with Stantec’s priority of maintaining balance sheet strength, while reinvesting in organic and acquisitive growth and increasing dividends, all of which contribute to enhanced shareholder returns.
