Ahlstrom to withdraw from Porous Power Technologies

Ahlstrom, a high performance fiber-based materials company, has decided not to
make any further investments in Porous Power Technologies, LLC. The U.S.-based
subsidiary has not been able to develop its nonwoven battery separator solution
into a product that would be qualified by potential customers.

As a consequence, the Board Members of Porous Power Technologies have decided to
wind down operations in an orderly manner. Ahlstrom will book net of tax an
impairment loss of approximately EUR 8 million in its third-quarter 2014
financial results. The impairment will not have any material cash effect.

Ahlstrom acquired a 49.5% stake in Porous Power Technologies in 2011 and now
holds approximately 60% of the shares in the company.
