Ahlstrom - Company Announcement

Preliminary information on Ahlstrom's Q3 financial result, full-year outlook weaker than anticipated

Ahlstrom Corporation STOCK EXCHANGE RELEASE 15.10.2008

According to preliminary information, Ahlstrom's net sales in
July-September 2008 is approximately MEUR 451.2 and operating profit
MEUR 11.4 excluding non-recurring items.

Ahlstrom revises its full-year outlook for 2008 due to the weakening
demand for some of its products. Operating profit excluding
non-recurring items is expected to be clearly lower than in 2007,
which was EUR 67.8 million.

Ahlstrom earlier estimated its full-year operating profit to be
almost at the level of last year. The estimate was based on a weaker
demand especially in the USA in a variety of products, e.g. wipes and
products for the building, automotive and marine industries. It has
now become evident that the demand is weakening in these product
segments also outside the USA. The company has taken actions to
adjust its production to the lower demand.

The demand for Ahlstrom's other products has still been growing and
the company anticipates its full-year net sales to increase from that
of 2007.

Ahlstrom will publish its January-September interim report on October
28, 2008.
