Oakville, Ontario – May 22, 2015 – Restaurant Brands International Inc. (TSX/NYSE: QSR, TSX: QSP) (“RBI”) and 1011778 B.C. Unlimited Liability Company and New Red Finance, Inc. (the “Issuers”) announced today that the Issuers have closed their previously announced private offering of $1,250 million in aggregate principal amount of 4.625% First Lien Senior Secured Notes (the “Notes”). The Notes were offered at an original issue price of 100.00% and will mature on January 15, 2022.

The net proceeds from the offering of the Notes, together with cash on hand, were used to repay approximately $1,550 million of the amount outstanding under the First Lien Term Loan Facility.

The Issuers also announced today the closing of the refinancing of their First Lien Term Loan Facility resulting in an interest rate reduction to LIBOR + 2.75% with a 1.00% LIBOR floor. The facility has a maturity date of December 12, 2021.
