Owned by Tokyo-based Seven & i Holdings Co. Ltd., 7-Eleven’s U.S. operations do more than three times the estimated domestic foodservice sales of its two closest rivals, Wawa and Circle K. 7-Eleven’s U.S. unit base is approximately 70 percent larger than that of the next largest player, Circle K, but its estimated foodservice sales per unit pales compared with smaller rival Sheetz, with average sales per location topping $1.1 million.
