Ahlstrom - Company Announcement

Ahlstrom completes divestment of Ascoli plant and assets

Ahlstrom Corporation STOCK EXCHANGE RELEASE 31.5.2011 at 16.45



Ahlstrom Corporation, a global high performance materials company, has completed
the divestment of the buildings, land and assets of its Ascoli plant in Italy to
Eurocomet. The transaction was announced on March 18, 2011.

The value of the transaction was approximately EUR 4.0 million euros. Ahlstrom
will book a non-recurring gain of approximately EUR 2.5 million in its second-
quarter financial results.

Ahlstrom permanently closed the Ascoli plant and ceased the production of one-
side coated papers there in early 2008 due to unsatisfactory profitability.
Eurocomet will develop the site for other purposes than paper making and the
machinery will be scrapped. Ahlstrom will keep some of the machinery parts.
