Ahlstrom Corporation STOCK EXCHANGE RELEASE May 23, 2013 at 8.30

Not to be distributed in or into Australia, Canada, the Hong Kong special
administrative region of the People's Republic of China, Japan, New Zealand,
South Africa or the United States.

Ahlstrom, a global high performance fiber-based materials company, announces
that the Brazilian competition authority (CADE) has approved the combination of
Ahlstrom's Label and Processing business and Munksjö AB. The approval from CADE
is a further step in the competition clearance process related to the
transaction.

In the first phase of the combination, the European part of Ahlstrom's Label and
Processing business, LP Europe, is combined with Munksjö. The first phase of the
transaction is expected to take place on May 27, 2013 at the latest, provided
that for example the competition clearance from the European Commission has been
obtained before that.

The approval from CADE is subject to the divestiture of Ahlstrom's abrasive
paper backings and pre-impregnated decor paper lines in Osnabrück, Germany to a
third party in accordance with the commitments provided to the Brazilian
competition authority, which are in line with those given to the EU Commission.


Ahlstrom has started to prepare for the divestiture process and is looking into
different alternatives to divest its abrasive backings and pre-impregnated decor
paper businesses.

The divestment process does not prevent Ahlstrom from closing the first phase of
the transaction, the combination of Ahlstrom's Label and Processing European
business (LP Europe) with Munksjö.
