THE GROWTH OF SALES DURING THE SECOND HALF YEAR WILL BE


Stonesoft Corporation stock exchange release September 26, 2007


THE GROWTH OF SALES DURING THE SECOND HALF YEAR WILL BE EMPHASIZED TO
THE LAST QUARTER - THE ANNUAL OVERALL NET SALES ARE DOWNGRADED


Based on the present information it seems that the growth of the
sales of StoneGate(TM) products during the second half year will be
emphasized to the last quarter as a consequence of among others a
transfer of timing of materialization of certain larger projects. The
sales of the third quarter will remain roughly at the same level than
last year or fall below.

The company has earlier estimated that its annual overall net sales
will be roughly 21 million euros (+/- 10%) and that its annual costs
will be roughly 23 million euros (+/- 10 %). Due to the weaker than
expected development of the sales during the third quarter, the
company expects now, in deviation of its earlier estimate, its annual
overall net sales to be roughly 19 million euros (+/- 10%). The
corresponding net sales figure of last year was 17 million euros.
This estimate is based on the present sales funnel. The annual costs
are estimated to remain in the level of 23 million euros (+/- 10 %)as
estimated earlier.

The operating result and the total result for the whole year is
expected to develop favourably as estimated earlier.

More detailed information will be given in connection with the
Interim Report for the third quarter to be announced in October 25,
2007.
