The Finnish Financial Supervisory Authority has today approved the Finnish
language version of the summary and securities note related to the share issue
of Munksjö Oyj in connection with the demerger of Ahlstrom Corporation's Label
and Processing business in Brazil (Coated Specialties). The summary and
securities note together with the registration document published on November
16, 2012 forms Munksjö Oyj's prospectus for the share issue.

The demerger is the second part of the process through which Ahlstrom's Label
and Processing business and Munksjö AB will be combined. According to the
demerger plan, all assets and liabilities that belong to Coated Specialties will
be transferred to Munksjö Oyj through a partial demerger of Ahlstrom
Corporation. Munksjö Oyj's and Ahlstrom Corporation's Board of Directors signed
a new demerger plan on May 13, 2013 related to Coated Specialties and cancelled
the previous demerger plan. The previous demerger plan was cancelled as not all
the relevant regulatory approvals were received before the expiration of the
decision made by Ahlstrom's Extraordinary General Meeting on November 27, 2012.

Ahlstrom Corporation has summoned an Extraordinary General Meeting on July
4, 2013 to approve the demerger of Coated Specialties and the completion of the
demerger is expected to take place by the end of 2013.

The prospectus contains the following previously unpublished information:

As trading in Munksjö's shares has commenced on NASDAQ OMX Helsinki, the
preliminary fair value of the consideration transferred for Coated Specialties
has been updated in the pro forma financials to correspond to the quoted market
price of Munksjö's share as at June 11, 2013 (EUR 6.10). Based on this share
price, the preliminary fair value of the consideration transferred amounts to
EUR 75.0 million whereas the preliminary fair value previously disclosed
amounted to EUR 112.4 million. Munksjö Oyj has recorded the difference of EUR
37.4 million as a decrease in goodwill and equity. The final consideration
transferred for Coated Specialties will be based on the quoted market price of
the Munksjö share at the date when the ownership over Coated Specialties to
Munksjö, and thus the final fair value for the consideration transferred and the
related goodwill will remain subject to change.

The Finnish language version of the prospectus together with an unofficial
English language translation will be available on Ahlstrom's website at
www.ahlstrom.com as of July 1, 2013 at the latest.
