Ahlstrom, a global high performance fiber-based materials company, announces
that the demerger of Ahlstrom's Label and Processing business in Europe (LP
Europe) has today been registered with the Finnish Trade Register. A total of
11,597,326 new shares in Munksjö Oyj were issued as demerger consideration to
Ahlstrom's shareholders in the LP Europe demerger.

This means that the total number of shares in Munksjö Oyj, following the
registration of the demerger and the two other shares issues with the Trade
Register on Monday morning, will amount to 38,769,590.

The second phase of the transaction, the demerger of Coated Specialties in
Brazil, is expected to the completed during the second half of this year.

·         Ahlstrom will continue to focus on high performance fiber-based
materials that purify air and liquids, protect people and provide surface and
structure to the customers' products.

·         Ahlstrom's shareholders will own shares in two listed companies,
Ahlstrom and Munksjö, both global leaders in their fields.

·         Ahlstrom's Label and Processing business in Europe had net sales of
EUR 562.5 million in 2012. Four plants and altogether about 1,000 employees will
transfer to Munksjö.

·         Right after the closing, Ahlstrom will buy back its operations in
Osnabrück, Germany. The wallpaper and hybrid wallcovering business will remain
with Ahlstrom, while the abrasive backings and pre-impregnated décor paper
businesses will be divested to a third party in accordance with the commitments
made to the EU Commission.

·         Ahlstrom becomes a major shareholder in Munksjö, holding a total of
23.4% per cent of the shares following the completion of the European part of
the transaction. After the completion of the Brazilian demerger, Ahlstrom's
shareholding in Munksjö will be 17.8%.

"The rationale for this transaction remains sound: Ahlstrom can now focus on
businesses in which we see the most attractive value-add and growth
opportunities. On the other hand, the Label and Processing business can be
further developed as part of a leading specialty paper company", said Jan Lång,
President & CEO, Ahlstrom.

 "Ahlstrom will now steer its resources fully towards high performance fiber-
based materials. We have made great progress with our product pipeline, and we
will utilize our improved capabilities in product and technology development to
introduce unique products that help our customers differentiate."

 "Our primary goal now is to raise profitability, and seek growth based on the
new product and technology platform now established. We are currently working
with our strategic agenda going forward, and will communicate more on this after
the summer holidays", Lång states.
