Ahlstrom starts a consultation procedure regarding the closure of its Chantraine plant

Ahlstrom Corporation STOCK EXCHANGE RELEASE 10.12.2007

Ahlstrom, a global leader in high performance fiber-based materials,
announced today that it has completed the review process of its
Chantraine plant in France. The company has informed the plant's
works council about the project to close the plant due to
unsatisfactory profitability and cash flow. Ahlstrom estimates to
book a non-recurring cost of approximately EUR 11 million related to
the closure in its fourth quarter result in 2007.

The closure, effective by the second quarter of 2008, would affect
approximately 120 people and reduce the annual production capacity of
one-side coated papers by approximately 30,000 tons.

Ahlstrom announced on October 10, 2007, that it would put the Italian
Ascoli and the French Chantraine plant under review due to
unsatisfactory profitability and cash flow. Both plants are part of
Ahlstrom's Release & Label Papers business area. On October 30, 2007,
Ahlstrom announced the closure of the Ascoli plant by mid-January
2008 and estimated to book a non-recurring cost of approximately EUR
15 million. The closure of the Ascoli plant affects 200 people and
reduces the annual production capacity of one-side coated papers by
approximately 65,000 tons.
