Profit warning: Uponor reduces full-year net sales estimate

Following a slower-than-expected start into the autumn season, Uponor adjusts its full-year guidance. The existing guidance, issued after Q1 and reconfirmed after Q2, of net sales growth being around 10 percent in 2007 is today downgraded to: - Uponor expects its full-year 2007 net sales growth rate to comply with the long-term target of a minimum 6 percent. This is the same net sales guidance that Uponor gave in February when announcing the 2006 financial results. Uponor's full-year operating profit is expected to be above the level recorded in 2006. The demand for Uponor products and services has been short of the management's expectations and prior year mostly in Germany and the US while also some other markets have not developed as well as expected. In addition, the euro-USD exchange rate development has a negative translation impact for Uponor. Uponor's January - September interim results are due 26 October 2007.
