7-Eleven is buying Speedway: Several locations in the Finger Lakes expected to continue operating

A massive $21 billion deal will mean some changes for local gas stations.

Japanese retail giant Seven & i Holdings, which owns 7-Eleven, is set to purchase the Speedway chain of gas stations from Marathon Petroleum

The deal is worth $21 billion, and would be the largest acquisition in company history.

It operates 9,800 stores in the U.S. and Canada. Once the purchase of Speedway is complete, it would add another 4,000 stores to it’s North American fleet.

7-Eleven would have a presence in 47 of the top 50 most populated metro areas in the United States, the company said in a press release.

Speedway has locations in Waterloo, Geneva, Auburn, Phelps, Newark, Canandaigua, Moravia, Shortsville, Cato, and Palmyra.

It’s unclear if branding of these stations would change, or if they would simply continue operation as Speedway.
