Eight Saks Fifth Avenue stores and a Neiman Marcus store in Boston will close as their parent company focuses on its most profitable businesses and pares down debt during its Chapter 11 bankruptcy restructuring. Saks Fifth Avenue’ stores that are closing include locations in Philadelphia; Columbus, Ohio and Phoenix. That will leave parent company Saks Global with 25 Saks Fifth Avenue stores and 35 Neiman Marcus stores. The company will continue to operate two Bergdorf Goodman stores. Saks Global also said it also will be winding down 14 standalone Fifth Avenue Club personal styling suites, though it will keep three standalone locations.
