You are receiving this notice to advise you that the Management Proxy Circular and Stella-Jones Inc.'s annual report, which includes, among other things, its management's discussion and analysis, the consolidated financial statements of Stella-Jones Inc. and the auditor's report for the fiscal year ended December 31, 2024, and other related materials (the "proxy materials") for the above noted shareholders' meeting are available on the Internet. This communication presents only an overview of the more complete proxy materials that are available to you on the Internet. "Notice-and-Access" is a set of rules that allows issuers to post electronic versions of proxy-related materials online, via SEDAR+ (under the issuer's profile) and one other website, rather than mailing paper copies of such materials to shareholders. We remind you to review all of the important information contained in the Management Proxy Circular and other proxy materials before voting.

The Management Proxy Circular and other relevant materials are available at:
