MATR MATTR Corporation

Shawcor Ltd., dba Mattr Infratech (“Mattr” or the “Company”) (TSX: MATR) announced today its Brazilian pipe coating facility has received a purchase order for the provision of thermal insulation coating for an offshore project in Brazil. The purchase order is valued over $50 million and will be executed from the Company’s Serra, Brazil facility in the first half of 2026.
