Tekla lowers its net sales and operating profit outlook for 2008

Tekla lowers its outlook for 2008. The company estimates that growth
of net sales will be approximately 10 percent. Profitability is
estimated to remain good and operating profit to be at the previous
year's level. Growth in the Building & Construction business area is
expected to outpace Infra & Energy.

According to the previous outlook, growth in net sales was expected
to be approximately 15 percent on the previous year and the operating
result to exceed that of the previous year.

Both estimates refer to continuing businesses (net sales 58.24
million euros and operating profit 17.90 million euros in 2007).

The growth of the construction industry is slowing down in several
central market areas, especially in the United States, and has
lengthened customers' decision-making times.  Additionally, the fall
of the US dollar rate has lowered B&C's net sales growth by about 3
percent during the first half of the year.

Tekla's long-term outlook remains good because the company has been
expanding its product offering. In the future, the construction
industry will be seeking ways of working that increase productivity,
which is expected to add demand for Tekla's 3D products.

Tekla will announce its Interim Report for January - June on August
8, 2008.
