Alimentation Couche-Tard could bolster its $47 billion offer for Seven & I if the Japanese firm became more cooperative and shared its financial information in greater detail, the founder of the Canadian retailer said on Thursday.

Canada’s Alimentation Couche-Tard has reiterated its determination to acquire Seven & i Holdings, although the operator of Japan’s top convenience store chain has rejected its offer.

Canadian convenience store and gas station operator Alimentation Couche-Tard Inc. said it could increase its offer to acquire long-time rival Seven & i Holdings Co., but only if the latter engages in takeover talks.
