CEO Doug Ewert, said: "We are thrilled to have closed on the acquisition of Jos.A Bank and are eager to begin the integration process. With more than 1,700 stores, approximately 26,000 employees and sales of $3.5bn on a pro forma basis, our combined company has increased scale and breadth that broadens our best-in-class offerings for our valued customers and new customers alike.

"Looking forward, our strong balance sheet provides operational flexibility to successfully execute strategic plans at both brands. We continue to expect this acquisition to be accretive to our earnings in the first full year of operations as well as to achieve $100 million to $150 million of run-rate synergies by the end of fiscal 2016."
