WestRock Company and KapStone Paper and Packaging Corporation announced the signing of a definitive agreement, pursuant to which WestRock will acquire all of the outstanding shares of KapStone for $35.00 per share and will assume approximately $1.36 billion in net debt, for a total enterprise value of approximately $4.9 billion.

WestRock will finance the cash consideration through the issuance of new debt under a fully committed financing package. WestRock expects to refinance existing KapStone debt assumed as part of the transaction upon closing. WestRock’s expected leverage ratio at the closing of the transaction will be greater than 3.00x, and WestRock expects to return to its stated leverage ratio target of 2.25x to 2.50x by the end of fiscal 2019. The transaction is not conditional on financing.

The transaction is subject to a number of customary closing conditions, including a vote by KapStone’s stockholders, and is expected to close during the quarter ending September 30, 2018. Upon completion of the transaction, KapStone will be integrated into WestRock’s Corrugated Packaging segment.

KapStone is a leading North American producer and distributor of containerboard, corrugated products and specialty papers, including liner and medium containerboard, kraft papers and saturating kraft.
