Business Description

Overview Smurfit Westrock was created in July 2024 as a strategic combination between Smurfit Kappa Group plc ( re-registered as Smurfit Kappa Group Limited) ( “Smurfit Kappa”), one of the leading integrated corrugated packaging manufacturers in Europe, with a large- scale pan-regional presence in Latin America, and WestRock Company (“WestRock”), one of the leaders in North America in corrugated and consumer packaging solutions and a multinational provider of sustainable fiber-based paper and packaging solutions. We are a global leader in sustainable, paper-based packaging with extensive scale, quality products and geographic reach and diversity . We aim to create the ‘go-to’ packaging partner of choice, bringing together highly complementary portfolios and sets of capabilities benefiting customers, employees and shareholders. Background Smurfit Westrock was incorporated and registered in Ireland on July 6, 2017, under the Irish Companies Act as a private company limited by shares with registered number 607515, with the name “Cepheidway Limited.” On September 12, 2023, Smurfit Kappa and WestRock announced entry into a transaction agreement pursuant to which the companies would execute a strategic combination (the “Combination”). Prior to the Combination, Smurfit Westrock re-registered as an Irish public limited company pursuant to Part 20 of the Companies Act 2014 of Ireland, as amended (the “Irish Companies Act”) and was renamed “Smurfit Westrock plc.” Upon completion of the Combination, Smurfit Kappa and WestRock each became wholly-owned subsidiaries of Smurfit Westrock, and Smurfit Westrock continued as the new holding company of the combined group of Smurfit Kappa and WestRock. As a result of the Combination, former Smurfit Kappa shareholders and WestRock shareholders became holders of Smurfit Westrock ordinary shares. Smurfit Westrock had no historical operations nor traded or carried out any business of its own since its incorporation until just prior to consummation of the Combination. Smurfit Westrock has a dual listing on the New York Stock Exchange (“NYSE”) and the equity shares (international commercial companies secondary listing) category of the Official List of the U.K. Financial Conduct Authority (“FCA”), and Smurfit Westrock ordinary shares trade on the NYSE and the London Stock Exchange’s main market for listed securities.
