Pursuant to the notice, Stella-Jones may, during the 12-month period commencing Nov. 14, 2025, and ending Nov. 13, 2026, purchase for cancellation, up to 1.5 million common shares, representing approximately 2.7 per cent of its outstanding common shares.

The average daily trading volume of the common shares on the TSX for the six-month period ended Oct. 31, 2025, was 91,822 common shares, and, therefore, in accordance with the requirements of the TSX, the daily purchase limit under the NCIB on the TSX will be 22,955 common shares, representing 25 per cent of the ADTV, subject to certain prescribed exceptions. The price that Stella-Jones will pay for any common shares acquired by Stella-Jones under the NCIB will be the market price of the common shares at the time of acquisition. Purchases will be made at management's discretion. Additionally, Stella-Jones has implemented an automatic share purchase plan with its designated broker in connection with the NCIB in order to allow, if deemed advisable by Stella-Jones, for share purchases during self-imposed blackout periods.

During the 12-month period commencing on Nov. 14, 2024, and ending on Nov. 13, 2025, the company was authorized, as approved by the TSX, to purchase for cancellation up to 2.5 million common shares.
