Canada’s convenience store and gas station operator Alimentation Couche-Tard says it has held "exploratory discussions” with buyers for any U.S. stores that would need to be divested to secure regulatory approval for a potential takeover of Japanese rival Seven & I Holdings.

Couche-Tard executives, including founder and chairman Alain Bouchard, will visit Tokyo next week to try and advance discussions with Seven & I, and are also planning to hold a news conference on Thursday to publicly present their case for buying the company behind 7-Eleven stores.

"We have identified a potential divestiture portfolio of U.S. stores,” Couche-Tard said in an emailed statement. "In collaboration with Seven & I, and to provide further assurance, Couche-Tard is having exploratory discussions with third parties to identify potential acquirers.”
