Gap is struggling to keep up with its sister stores.

Gap Inc., the parent company of Gap, Banana Republic, Old Navy, and Athleta, saw flat sales this quarter. Prior to this quarter, the company saw seven consecutive quarters of positive comparable sales growth.

“We are clearly not satisfied with the performance of Gap brand.
