\*\*\*

***\* A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.***

\*\* Delivery of the Notes will be made to investors on or about November 24, 2025, which will be the fourth business day in New York following the date of pricing of the Notes (such settlement being referred to as "T+4"). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to their date of delivery will be required, by virtue of the fact that the Notes initially settle in T+4, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes on a date that is prior to the first business day prior to delivery of the Notes should consult their own advisor.

**Smurfit Westrock has filed a registration statement (including a base prospectus) and the Preliminary Prospectus Supplement with the U.S. Securities and Exchange Commission (the "SEC") for the offering to which this communication relates. Before you invest, you should read the Preliminary Prospectus Supplement, the accompanying base prospectus in that registration statement, this Pricing Term Sheet and other documents Smurfit Westrock has filed with the SEC for more complete information about Smurfit Westrock and this Offering. You may obtain these documents for free by visiting EDGAR on the SEC's website at www.sec.gov. Alternatively, Smurfit Westrock, any underwriter or any dealer participating in this Offering will arrange to send you the Preliminary Prospectus Supplement, the final prospectus supplement (when available) and the accompanying base prospectus if you request it by calling Citigroup Global Markets Limited at +1-800-831-9146 (toll free), Barclays Bank Ireland PLC at +1-888-603-5847 (toll free), Commerzbank Aktiengesellschaft at +33 1 44 94 77 10 and Goodbody Stockbrokers UC at + 353 1 667 0400.**

The Notes are not intended to be offered, sold or otherwise made available to, and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (the "**EEA**"). For these purposes, a retail investor means a person who is one (or more) of (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, "**MiFID II**"), (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the "Insurance Distribution Directive"), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II, or (iii) not a "qualified investor" as defined in Article 2 of Regulation (EU) 2017/1129 (as amended, the "Prospectus Regulation"). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the "**PRIIPs Regulation**") for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (the "**UK**"). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended, the "**EUWA**"); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, the "**FSMA**") and any rules or regulations made under the FSMA to implement the Insurance Distribution Directive, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of the Prospectus Regulation as it forms part of domestic law by virtue of the EUWA. Consequently, no key information document required by the PRIIPs Regulation as it forms part of domestic law by virtue of the EUWA (the "**UK PRIIPs Regulation**") for offering or selling the Notes or otherwise making them available to retail investors in the UK has been prepared and, therefore, offering or selling the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

In the UK, this final term sheet is for distribution only to persons who (i) have professional experience in matters relating to investments and qualifying as investment professionals falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended, the "Financial Promotion Order"), (ii) are persons falling within Article 49(2)(a) to (d) ("high net worth companies, unincorporated associations etc.") of the Financial Promotion Order, or (iii) are persons to whom an invitation or inducement to engage in investment activity (within the meaning of section 21 of the FSMA) in connection with the issue or sale of any securities may otherwise lawfully be communicated or caused to be communicated (all such persons together being referred to as "relevant persons"). In the UK, this final term sheet is directed only at relevant persons and must not be acted on or relied on by persons who are not relevant persons. Any investment or investment activity to which this document relates is available in the UK only to relevant persons and, in the UK, will be engaged in only with relevant persons.

Solely for the purposes of the product approval process of the manufacturers, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is eligible counterparties and professional clients only, each as defined in MiFID II; and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Notes (a "**distributor**") should take into consideration the manufacturers' target market assessment; however, and without prejudice to the Issuer's obligations in accordance with MiFID II, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturers' target market assessment) and determining appropriate distribution channels.

Solely for the purposes of each manufacturer's product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the such Notes is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook, and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; and (ii) all channels for distribution of such securities to eligible counterparties and professional clients are appropriate. Any distributor should take into consideration the manufacturers' target market assessment; however, a distributor subject to the FCA Handbook Intervention and Product Governance Sourcebook is responsible for undertaking its own target market assessment in respect of such securities (by either adopting or refining the manufacturers' target market assessment) and determining appropriate distribution channels.
