OKMETIC REVISES ITS GUIDANCE FOR 2012 DOWNWARD

OKMETIC OYJ STOCK EXCHANGE RELEASE 20 SEPTEMBER 2012 AT 11.15 A.M. OKMETIC REVISES ITS GUIDANCE FOR 2012 DOWNWARD Okmetic revises its estimate on net sales and operating profit for 2012 given on 8 February 2012. The net sales for 2012 are estimated to settle approximately at the level of 2011. Operating profit is estimated to remain slightly under the level of 2011. According to the earlier guidance, Okmetic's net sales and operating profit were estimated to exceed the level of 2011. The following factors have contributed to the revision of the guidance: * The technology sales that consist mainly of solar crystal sales are at a lower level than before and significantly less profitable in the second half of 2012 due to the lowered price level and termination of the long-term crystal growing contracts. * The uncertainty of the global economy has reduced the predictability of the order backlog for the rest of the year. Customers are lowering their stock levels and postponing orders partly over the turn of the year. * The earlier reported disturbance in the production chain of a gas used in the manufacture of epi-coated wafers in the USA caused a long shutdown in the Allen production facility, which weakened the operating profit of the first quarter significantly. Contrary to expectations, this deficit in operating profit cannot be covered during the rest of the year due to the weakened demand for epi wafers. The demand for demanding sensor wafers which are chosen as Okmetic's long-term strategic focus area will continue to be steady also in the end of the year. The total sales of silicon wafers manufactured by the company will grow in absolute terms and clearly faster than the market also in 2012.
