The deal to acquire more than 1,500 locations in 13 states values North Carolina-based Pantry (Nasdaq:PTRY) at US$1.7 billion, with Couche-Tard paying US$36.75 cash per share.
The purchase price includes more than US$860 million to purchase Pantry's shares, with the rest going towards capital leases and debt.
The deal, which was supported by about 99 per cent of the votes cast at a meeting of Pantry shareholders on Tuesday, is still subject to customary closing conditions, including governmental and regulatory approvals.
The waiting period under the U.S. Hart-Scott-Rodino Act is scheduled to expire on Thursday.
Couche-Tard's network of convenience stores and filling stations operate primarily under the Couche-Tard and Mac's banners in Canada as well as Circle K throughout the United States.
