Albertsons announced that its Safeway/Eastern and Acme Markets divisions will merge to form Albertsons’ Mid-Atlantic division, effective September 13. The Mid-Atlantic division will be located in Malvern, PA, which is Acme’s current headquarters. The Safeway/Eastern office is currently in Lanham, MD.

The merger will make the Mid-Atlantic division Albertsons’ third largest in terms of store counts behind Southern California and Northern California. There are 275 supermarkets that range from Fairfield County, CT to Culpeper County, VA with annual sales of approximately $6 billion. (That comes to nearly $22 million in sales per store.)

Acme President Jim Perkins will become president of the Mid-Atlantic division.
