Ahlstrom - Company Announcement

Ahlstrom starts co-operation negotiations at Karhula and Mikkeli plants

Ahlstrom Corporation STOCK EXCHANGE RELEASE 24.8.2011 at 10.20

Ahlstrom Corporation, a global high performance materials company, will start on
September 1, 2011, co-operation negotiations with employee representatives at
its Karhula and Mikkeli plants in Finland. The negotiations concern all
personnel at the sites, with the aim of improving profitability of the units.

Ahlstrom manufactures glassfiber, specialty reinforcements and glassfiber tissue
in Karhula and Mikkeli. Previous efficiency improvement measures implemented at
the sites have not been sufficient. Profitability has weakened as competition,
particularly in glassfiber markets and specialty reinforcements used by the wind
energy industry, has intensified significantly. In addition, the company has not
been able to fully compensate for the increased raw material and energy costs by
higher selling prices.

The plants in Karhula and Mikkeli are part of Ahlstrom's Building and Energy
Business Area. The Karhula plant employs 267 permanent employees, of whom 190
are blue-collar and 77 white-collar. The Mikkeli plant employs 135 permanent
employees, of whom 97 are blue-collar and 38 white-collar. In case the
negotiations lead to personnel reductions, Ahlstrom estimates a maximum of 230
persons to be impacted. Temporary layoffs are also discussed in the
negotiations.
