ATLANTA, September 27, 2023--(BUSINESS WIRE)--WestRock Company ("WestRock") today announced the results of the consent solicitation through which its wholly-owned subsidiary WRKCo Inc. (the "Issuer") solicited consents ("Consents") from registered holders ("Holders") of the Notes (the "Consent Solicitation") to amend certain terms of the indentures governing the respective Notes (each, an "Indenture" and together, the "Indentures"). Adoption of the proposed amendments with respect to the applicable Indenture for each series of Notes requires the Consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes of such series.

The Consent Solicitation expired at 5:00 P.M., New York time, on September 26, 2023 (the "Expiration Time"). As of the Expiration Time, the Issuer had received Consents from Holders of the majority in aggregate principal amount of the outstanding Notes of each series. As a result, supplemental indentures reflecting the proposed amendments with respect to the applicable Indenture for each series of Notes were executed on September [26], 2023.

In addition, revocation rights with respect to each series of Notes were terminated at [5:00] P.M., New York time, on September [26], 2023 (the "Revocation Deadline"). A Holder who delivered a valid Consent for a series of Notes prior to the Expiration Time and did not validly revoke such Consent prior to the Revocation Deadline, will receive a payment equal to $1.50 per $1,000 aggregate principal amount of the relevant series of Notes with respect to which such Consent was delivered (the "Consent Payment"). Holders who validly delivered their Consents prior to the Expiration Time but who validly revoked their Consents prior to the Revocation Deadline will not receive the Consent Payment unless they validly delivered their Consents again prior to such Expiration Time and did not validly revoke their Consents again prior to the Revocation Deadline. The Consent Payment is expected to be paid on September [28], 2023 by Smurfit Kappa Group plc ("SKG").

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: legal proceedings are instituted against SKG or WestRock; 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 SKG 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 risks and uncertainties discussed in the "Risks and Uncertainties" section in SKG’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 Securities and Exchange Commission (the "SEC").
