Cautionary Statements Regarding Forward-Looking Statements

Any statements in this communication about WestRock’s expectations, beliefs, plans or forecasts, including statements regarding WestRock’s expectation that the pending acquisition will close on November 2, 2018, that are not historical facts are forward-looking statements. These statements are typically identified by words or phrases such as “may,” “will,” “could,” “should,” “would,” “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “target,” “prospects,” “potential” and “forecast,” and other words, terms and phrases of similar meaning.  Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties. WestRock cautions readers that a forward-looking statement is not a guarantee of future performance, and actual results could differ materially from those contained in forward-looking statements.  Among the key factors that could cause actual results to differ materially from those projected in the forward-looking statements, are the following: the parties’ ability to consummate the transaction; the conditions to the completion of the transaction; and the parties’ ability to meet expectations regarding the timing, completion and accounting and tax treatments of the transaction. Additional information and other factors are contained in WestRock’s Annual Report on Form 10-K for the fiscal year ended September 30, 2017, WestRock’s Quarterly Reports on Form 10-Q for the quarters ended December 31, 2017, March 31, 2018 and June 30, 2018, recent Current Reports on Form 8-K and recent Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission (“SEC”). Because the factors referred to above could cause actual results or outcomes to differ materially from those expressed or implied in any forward-looking statements made by WestRock, you should not place undue reliance on any such forward-looking statements. Further, any forward-looking statement speaks only as of the date of this communication, and WestRock and KapStone undertake no obligation to update any forward-looking statement to reflect events or circumstances after such date, except as required by applicable law.
