Payment of the Notes will be guaranteed on an unsecured basis by certain wholly-owned subsidiaries of Stella-Jones. The Notes have been assigned a provisional rating of “BBB”, with a stable trend, by DBRS Limited.*

This press release shall not constitute an offer to sell or a solicitation of an offer to buy any of the Notes in the United States or any other jurisdiction where such offering or sale would be unlawful.
