WestRock Company and KapStone Paper and Packaging Corporation announced that the U.S. Department of Justice has cleared WestRock's pending acquisition of KapStone through Whiskey Holdco Inc. As this was the last antitrust approval required to complete the pending acquisition, WestRock and KapStone expect the pending acquisition to close on November 2, 2018, subject to customary closing conditions. As a result of the acquisition, among other things, Holdco will become the ultimate parent of WestRock, KapStone and their respective subsidiaries.
