Ahlstrom Corporation STOCK EXCHANGE RELEASE 10.10.2007 at 14.00 Ahlstrom's 2007 full year operating profit excluding non-recurring items is expected to be somewhat below the 2006 level (EUR 87.3 million). The primary reasons for the decrease in operating profit are continuously rising raw material and energy costs as well as the weakening demand in the Label & Packaging Papers business area. The Technical Papers business area, which is part of Ahlstrom's Specialty Papers segment, as well as the FiberComposites segment are expected to improve their operating profit from 2006. Implemented growth investments and acquisitions are expected to increase Ahlstrom's net sales by over 10% compared to 2006 (EUR 1,599.1 million) despite the weaker USD. Ahlstrom will publish a separate announcement regarding a profitability improvement plan for the Label & Packaging Papers business area. Ahlstrom will publish its January-September interim report on October 26, 2007.
