Ahlstrom - Company Announcement

Ahlstrom to exit Dust Filtration material businesses; Sells Wuxi plant and machinery in Bethune to Andrew Industries

Ahlstrom Corporation STOCK EXCHANGE RELEASE 7.12.2010 at 16.35

Ahlstrom, a global leader in nonwovens and specialty papers, today announces the
exit from most of its Dust Filtration material businesses through the sale of
the Wuxi plant in China and three production lines in Bethune in the USA to
Andrew Industries.

The value of the transaction is approximately EUR 5.3 million. Dust Filtration
is part of Ahlstrom's Filtration Business area.

Both plants make dust filtration materials used in applications such as bag
house filtration for pollution control. Ahlstrom has concluded that dust
filtration materials produced at the Wuxi and Bethune sites do not fit
strategically its product portfolio.

The Wuxi plant in the Jiangshu province employs about 40 people.

In Bethune, South Carolina, Andrew will transfer the three dust filtration
production lines to its own sites. The transaction will affect the 48 people
employed at the Dust Filtration business, while Ahlstrom will investigate
possibilities to offer employment for some of the staff. The Bethune plant
currently employs about 190 people in total. Ahlstrom will continue to
manufacture nonwovens for wipes and advanced liquid filtration products at the
site.

Both transactions are expected to be completed by the end of first quarter
2011. Ahlstrom will book approximately EUR 5.2 million as a non-recurring loss
from the transaction in its fourth-quarter 2010 financial results. The
completions of the transactions are subject to customary closing terms.

Asia remains a key strategic growth region for Ahlstrom. The company acquired in
September a transportation filtration material plant in Binzhou, China and
announced in October a joint venture with Yulong Paper Co. in Longkou for
production of crepe papers in the country. The Group currently generates about
10 percent of its annual net sales from Asia.
