This Current Report on Form 8-K includes certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Except for historical information, the matters discussed in this Current Report on Form 8-K are forward-looking statements subject to certain risks and uncertainties. Forward-looking statements can often be identified by words such as “may,” “will,” “should,” “would,’ “expect,” “project,” “anticipate,” “intend,” “plan,” “believe,” “estimate,” “potential,” “outlook,” or “continue,” the negative of these terms or other similar expressions. Actual results may differ materially from those projected as a result of certain risks and uncertainties, including but not limited to the ability of KapStone and WestRock to receive the required regulatory approvals for the proposed acquisition of KapStone by WestRock (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction) and to satisfy the other conditions to the closing of the proposed transaction on a timely basis or at all; the occurrence of events that may give rise to a right of one or both of the parties to terminate the merger agreement; negative effects of the announcement or the consummation of the transaction on the market price of WestRock’s or KapStone’s common stock and/or on their respective businesses, financial conditions, results of operations and financial performance; risks relating to the value of the Holdco shares that may be issued in the transaction, significant transaction costs and/or unknown liabilities; the possibility that the anticipated benefits from the proposed transaction cannot be realized in full or at all or may take longer to realize than expected; risks associated with third party contracts containing consent and/or other provisions that may be triggered by the proposed transaction; risks associated with transaction-related litigation; the possibility that costs or difficulties related to the integration of KapStone’s operations with those of WestRock will be greater than expected; the outcome of legally required consultation with employees or other employee representatives; and the ability of KapStone and the combined company to retain and hire key personnel. There can be no assurance that the proposed transaction will in fact be consummated in the manner described or at all. For additional information on identifying factors that may cause actual results to vary materially from those stated in forward-looking statements, see the reports of WestRock and KapStone on Forms 10-K, 10-Q and 8-K filed with or furnished to the SEC from time to time.
