7-Eleven’s parent company is considering a massive management buyout that would take it private and end a takeover attempt by Alimentation Couche-Tard.

The effort, which brings together a member of the company’s founding family, a giant trading company and some of Japan’s largest banks, is the latest twist in the battle for control of one of Japan’s most successful enterprises and one of the world’s best-recognized brands.

In a statement released Wednesday, Seven & I Holdings said that it has received a nonbinding offer for the company from Junro Ito, a vice president and representative director of the company, and Ito Kogyo, a company connected to him.
