Ahlstrom Corporation STOCK EXCHANGE RELEASE November 29, 2013 at 9.00

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.

The Board of Directors of Ahlstrom Corporation and Munksjö Oyj have today resolved to execute the demerger of Ahlstrom's Label and Processing business in Brazil and notify it for registration with the Finnish Trade Register on December 2, 2013.

The demerger is the final step in the process through which Ahlstrom's Label and Processing business and Munksjö AB are combined.

In the demerger the shareholders of Ahlstrom receive as demerger consideration 0.265 new shares in Munksjö for each share owned in Ahlstrom. An estimated total of 12,292,084 new shares in Munksjö Oyj will be issued as demerger consideration to Ahlstrom's shareholders.

The number of new shares to be issued as demerger consideration will be determined based on the shareholding in Ahlstrom and taking into account all trades made, although not settled, in Ahlstrom's shares by the end of today. In case the number of shares received by a shareholder of the company as Coated Specialties demerger consideration would be a fractional number, the fractions shall be rounded down to the nearest whole number.

No demerger consideration will be paid on the basis of own shares held by Ahlstrom Corporation. The new Munksjö shares carry a right to dividend and other shareholder rights as from their registration, expected to occur on December 2, 2013. The trading with Munksjö's shares received as a demerger consideration in the Coated Specialties demerger is expected to commence on the Helsinki Stock Exchange on or about December 2, 2013.

The process does not require any action from the current Ahlstrom shareholders.
