The U.S. Department of Justice last week approved a $3.5 billion merger between WestRock Co. and KapStone Paper and Packaging Corp., a deal that makes the combined company one of the largest producers of paper and packaging products in the nation.
WestRock announced the decision on Oct. 30 after completion of an antitrust review with the Justice Department. In a press release, WestRock said last week that the merger would be completed by late last week.
