Ahlstrom - Company Announcement

Ahlstrom updates 2011 outlook for net sales and operating profit

Ahlstrom Corporation STOCK EXCHANGE RELEASE 18.10.2011 at 09.45

Ahlstrom Corporation's sales volume development in the second half of 2011 has
been weaker than earlier anticipated due to the slowdown in its main markets.
The lower than expected demand has had an adverse impact on the company's net
sales and operating profit, particularly in the Label and Processing business
area.

As a result, Ahlstrom updates its 2011 outlook for net sales and operating
profit excluding non-recurring items from continuing operations. The company now
estimates net sales to be EUR 1,565-1,645 million and operating profit excluding
non-recurring items of EUR 46-56 million. Ahlstrom had previously expected net
sales to be at EUR 1,580-1,740 million and operating profit excluding non-
recurring items of EUR 67-87 million. Both the new and the previous guidance
exclude figures from Home and Personal business area. The divestment of Home and
Personal to Suominen Corporation is expected to be completed by the end of
October 2011.

Ahlstrom will take firm action to address its underperforming businesses and to
further streamline its cost structure to gain efficiencies in the supply chain
base. More information on these actions will be announced in a separate release
today.

The company will publish its interim results for January-September on October
24, 2011.
