Ahlstrom Divests Sonoco-Alcore Shares

Finland-based Ahlstrom Corp. has sold
its 35.5-percent stake in Brussels-based Sonoco-Alcore S.á.r.l., to Hartsville, S.C.-based Sonoco
Products Co., owner of the majority 64.5-percent stake in the joint venture, for 39.5 million
euros. Sonoco-Alcore was formed in November 2004 to merge the two companies’ industrial core, tube
and core-board operations in Europe.

Ahlstrom sold its interest in the joint venture as part of its strategy to divest assets not
related to its fiber-based materials operations, which include the manufacture of nonwovens and
specialty papers for applications such as filters, flooring, labels, tapes and wipes.

Sonoco-Alcore operates 28 tube and core manufacturing facilities and six paper mills. The
company realized net sales of approximately 270 million euros in 2005.
