Ahlstrom - Company Announcement

Ahlstrom to exit Sealing & Shielding business through the sale of Altenkirchen site in Germany

Ahlstrom Corporation STOCK EXCHANGE RELEASE 3.12.2010 at 11.30

Ahlstrom Corporation, a global leader in nonwovens and specialty papers, has
today signed an agreement to exit its Sealing & Shielding business unit through
the sale of Ahlstrom Altenkirchen GmbH in Germany. The acquirer is Interface
Solutions, a portfolio company of Pennsylvania-based family owned private equity
fund Susquehanna Capital.

The value of the transaction is approximately EUR 6.5 million.

Ahlstrom Altenkirchen GmbH, which is part of Ahlstrom's Label and Processing
Business Area, is located in the German state of Rheinland-Pfalz. The plant has
two paper machines and employs approximately 130 people. Its products include
gasket and heat shield materials for the automotive industry and calender bowl
materials for the paper industry.

Products manufactured by the Altenkirchen site differ technically from the other
nonwoven and specialty paper products made by Ahlstrom and therefore do not fit
strategically with the company's portfolio. Interface Solutions is a global
leader in gasket materials for the automotive industry.

It is anticipated that the transaction will be completed by the end of 2010.
Ahlstrom will book a non-recurring gain of approximately EUR 5 million from the
transaction in its fourth-quarter financial results. The completion of the
transaction is subject to customary closing conditions.

Ahlstrom's Label and Processing Business Area will continue to operate six
production sites in France, Germany, Italy and Brazil.
