Not for release, publication or distribution, in whole or in part, in or into the United States, Canada, Australia or Japan.
The Board of Directors of Ahlstrom Corporation has decided that Ahlstrom will issue a total of 8,000,000 of its shares in its initial public offering. The decision is based on the resolution of the company's annual general meeting of February 14, 2006. The shares to be issued represent approximately 18.0 percent of the total number of shares in Ahlstrom Corporation after the offering. Both the institutional offering and the retail offering have been priced at EUR 22.00 per share. The gross proceeds to Ahlstrom Corporation from the offering will be approximately EUR 176.0 million and the net proceeds after deduction of underwriters' commissions will be approximately EUR 172.1 million.
 
In addition, Ahlstrom Corporation has granted SEB Enskilda an option, exercisable for 30 days from the date of pre-listing of the shares on the Helsinki Stock Exchange Ltd., to subscribe for 1,150,000 additional new shares at the offer price solely to cover over-allotments. If the over-allotment option is exercised the gross proceeds to Ahlstrom Corporation from the offering of these shares will be approximately EUR 25.3 million and the net proceeds after deduction of underwriters' commissions will be approximately EUR 24.7 million. In addition, Ahlstrom Corporation may decide on March 22, 2006 to pay to the underwriters an additional fee of no more than 1.0 million euros. Ahlstrom Corporation intends to use the proceeds of the offering to expand and further improve its operations, as well as for general corporate purposes.
 
Initially the institutional offering comprised 7,300,000 and the retail offering 700,000 shares. The institutional offering was approximately 9.5 times subscribed at the offer price and the Finnish retail offering was approximately 6.6 times subscribed according to the share amounts stated in the initial terms. It has been decided on March 13, 2006 by the board that 6,600,000 shares will be allocated to institutional investors and 1,400,000 shares to retail investors. In total 14,159 investors participated in the retail offering. Approximately 43 percent of the demand in the institutional offering came from Finnish investors and approximately 57 percent from international investors.
 
Antti Ahlströmin Perilliset Oy was granted the right to maintain its proportional shareholding in the company, assuming that SEB Enskilda exercises the over-allotment option in full.
 
In the retail offering, subscription commitments will be fully accepted up to 50 shares. For commitments exceeding 50 shares, investors in the retail offering will be additionally allocated approximately 18 percent of the amount exceeding 50 shares. Allocations exceeding 50 shares will be rounded to the nearest round lot. The lot size is 50 shares.
 
Participants in the retail offering will be sent a confirmation of accepted subscriptions on or about March 20, 2006. Excess payments made in connection with the subscription commitments will be returned to investors on or about March 16, 2006.
 
The listing of the shares of Ahlstrom Corporation is scheduled to commence on the Prelist of the Helsinki Exchange on or about March 14, 2006 and on the Main List on or about March 17, 2006.
