Exhibit 99.1 Rock-Tenn Company Announces Closure of Marshville Folding Carton Facility NORCROSS, Ga.--(BUSINESS WIRE)--Oct. 4, 2005--Rock-Tenn Company (NYSE: RKT) announced today its decision to close its Marshville, North Carolina, folding carton plant in the second quarter of fiscal 2006. Rock-Tenn will transfer the majority of the Marshville facility's current production to its Marion and McDowell plants, which are also located in North Carolina. Mike Kiepura, Executive Vice President - Folding Carton division, stated, "As a result of the Gulf States acquisition, we are currently operating three folding carton plants that manufacture high value adding - packaging in a small geographic area. Consolidating operations in Marion and McDowell will enable the company to best service its diverse customer base and optimize its network of manufacturing facilities." Of the $4.6 million in total closing costs expected to be inccured, Rock-Tenn Company expects to incur cash operating and restructuring costs of approximately $1.7 million, which will include severance and relocation costs. The Marshville closure is expected to generate approximately $2 million of annualized synergies that will contribute to the $20 million of synergies that Rock-Tenn expects to realize following its acquisition of Gulf States' paperboard and packaging businesses. Rock-Tenn Company provides a wide range of marketing and packaging solutions to consumer products companies at low costs, with combined pro forma net sales of $2.1 billion and operating locations in the United States, Canada, Mexico and Chile. The Company is one of North America's leading manufacturers of packaging products, merchandising displays and bleached and recycled paperboard.
