Bain Capital aims to list Seven & i Holdings' supermarket and retail business in around three years after boosting synergies within the group, an executive of the U.S. private equity firm said on Thursday.

Bain Capital said it intends to pursue further deals to grow a Japanese supermarket company it acquired from Seven & i Holdings Co., while seeking to take it public in three years.

Japan's Seven & I, the parent company of the Japanese 7-Eleven convenience store chain, says it is selling its supermarket store assets to Bain Capital for about $5.4 billion.
