Mattr Corp. (“Mattr” or the “Company”) (TSX: MATR) announced that it has successfully closed on its credit facility (the “Credit Facility”) with The Toronto-Dominion Bank and National Bank Financial Markets as Co-Lead Arrangers and Joint Bookrunners, and Royal Bank of Canada, JP Morgan Chase Bank, Export Development Canada and ATB Financial as lenders. The Credit Facility extends the US$300 million senior secured revolving facility through April 2028.
