Ahlstrom Corporation Stock Exchange Release 9.5.2007 Ahlstrom, a global leader in fiber-based materials, today announced that it has signed an agreement with Brazilian Votorantim Celulose e Papel (VCP) to form a joint venture for specialty paper production in Brazil. Ahlstrom will hold 60% and VCP 40% of the shares in the joint venture. The price for Ahlstrom's shareholding is approximately EUR 80 million and the transaction is expected to be EPS enhancing from 2007. In February 2007, the parties announced they had signed a Memorandum of Understanding to form a joint venture. The assets in the joint venture, currently owned by VCP, comprise a paper machine, an offline coater and extensive finishing equipment at the Jacarei mill, close to São Paulo. The annual production capacity of the paper machine is approximately 110 000 tons and net sales approximately EUR 100 million. The joint venture will be part of Ahlstrom's Specialty Papers segment serving mainly the labeling applications and certain flexible packaging markets. Additionally, it will continue to produce coated and uncoated paper grades for other end uses. Currently, the majority of the paper production is targeted to the local markets but Ahlstrom aims to expand the customer base by utilizing its global sales network. The Jacarei facility is an integrated pulp and paper mill and one of the most modern and competitive eucalyptus pulp producers in the world with a production capacity of 1.1 million tons per year. The parties have also negotiated a long-term agreement whereby VCP will supply eucalyptus pulp, utilities and other services to Ahlstrom's operations at the Jacarei mill at competitive prices."The joint venture with the state of the art assets allows us to enter the rapidly growing labeling and packaging markets in Latin America. In addition, it further strengthens our position as the global leader in the specialty paper markets. After the closing of the transaction, Latin American markets will generate approximately 10% of Ahlstrom's net sales", comments Jukka Moisio, President and CEO of Ahlstrom. The deal is expected to be closed during the third quarter of 2007, and is subject to antitrust clearances. Under the terms of the agreement, Ahlstrom has an option to purchase the remaining share in the joint venture held by VCP after two years time. The global market for Ahlstrom's label and packaging papers is estimated to grow 3-4% annually with the double-digit growth rates seen in Latin America and Asia.
