3 INFORMATION REGARDING FORWARD LOOKING INFORMATION This presentation contains forward-looking statements as that term is defined in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended by the Private Securities Litigation Reform Act of 1995. These forward-looking statements generally include statements regarding the Combination between Westrock and Smurfit Kappa, including any statements regarding the Combination and the listing of Smurfit Westrock, the rationale and expected benefits of the Combination (including, but not limited to, synergies), and any other statements regarding Westrock's and Smurfit Kappa's future expectations, beliefs, plans, objectives, results of operations, financial condition and cash flows, or future events or performance. Forward-looking statements can sometimes be identified by the use of forward-looking terms such as "believes,” “expects,” “may,” “will,” “shall,” “should,” “would,” “could,” “potential," "seeks," "aims," "projects," "predicts," "is optimistic," "intends," "plans," "estimates," "targets," "anticipates," "continues" or other comparable terms or negatives of these terms or other variations or comparable terminology or by discussions of strategy, plans, objectives, goals, future events or intentions, but not all forward-looking statements include such identifying words. Forward-looking statements are based upon current plans, estimates and expectations that are subject to risks, uncertainties and assumptions. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those indicated or anticipated by such forward-looking statements. We can give no assurance that such plans, estimates or expectations will be achieved and therefore, actual results may differ materially from any plans, estimates or expectations in such forward-looking statements. Important factors that could cause actual results to differ materially from such plans, estimates or expectations include: a condition to the closing of the Combination may not be satisfied; the occurrence of any event that can give rise to termination of the Combination; a regulatory approval that may be required for the Combination is delayed, is not obtained in a timely manner or at all or is obtained subject to conditions that are not anticipated; Smurfit Kappa is unable to achieve the synergies and value creation contemplated by the Combination; Smurfit WestRock's availability of sufficient cash to distribute to its shareholders in line with current expectations; Smurfit Kappa is unable to promptly and effectively integrate WestRock's businesses; management's time and attention is diverted on issues related to the Combination; disruption from the Combination makes it more difficult to maintain business, contractual and operational relationships; credit ratings decline following the Combination; legal proceedings are instituted against Smurfit Kappa or WestRock; Smurfit Kappa or WestRock are unable to retain or hire key personnel; the announcement or the consummation of the Combination has a negative effect on the market price of the capital stock of Smurfit Kappa or WestRock or on Smurfit Kappa or WestRock's operating results; evolving legal, regulatory and tax regimes; changes in economic, financial, political and regulatory conditions, in Ireland, the United Kingdom, the United States and elsewhere, and other factors that contribute to uncertainty and volatility, natural and man-made disasters, civil unrest, pandemics (e.g., the coronavirus (COVID-19) pandemic (the "COVID-19 pandemic")), geopolitical uncertainty, and conditions that may result from legislative, regulatory, trade and policy changes associated with the current or subsequent Irish, U.S. or U.K. administrations; the ability of Smurfit Kappa or WestRock to successfully recover from a disaster or other business continuity problem due to a hurricane, flood, earthquake, terrorist attack, war, pandemic, security breach, cyber- attack, power loss, telecommunications failure or other natural or man-made event, including the ability to function remotely during long-term disruptions such as the COVID-19 pandemic; the impact of public health crises, such as pandemics (including the COVID-19 pandemic) and epidemics and any related company or governmental policies and actions to protect the health and safety of individuals or governmental policies or actions to maintain the functioning of national or global economies and markets; actions by third parties, including government agencies; the risk that disruptions from the Combination will harm Smurfit Kappa's or WestRock's business, including current plans and operations; certain restrictions during the pendency of the Combination that may impact Smurfit Kappa's or WestRock's ability to pursue certain business opportunities or strategic transactions; Smurfit Kappa's or WestRock's ability to meet expectations regarding the accounting and tax treatments of the Combination; the risks and uncertainties discussed in the "Risks and Uncertainties" section in Smurfit Kappa's reports available on the National Storage Mechanism at https://data.fca.org.uk/#/nsm/nationalstoragemechanism and on its website at https://www.smurfitkappa.com/investors; and the risks and uncertainties discussed in the "Risk Factors" and "Information Regarding Forward-Looking Statements" sections in WestRock's reports filed with the SEC.

The list of factors presented here should not be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. We caution you not to place undue reliance on any of these forward-looking statements as they are not guarantees of future performance or outcomes and that actual performance and outcomes, including, without limitation, the actual results of operations, financial condition and liquidity, and the development of new markets or market segments in which we operate, may differ materially from those made in or suggested by the forward-looking statements contained in this presentation.
