Uponor announces pro forma segment information for 2009

Uponor Corporation Stock exchange release 22 April 2010 Uponor announces pro forma segment information for 2009 Since 1 January 2009, Uponor has applied three segments in its financial reporting. These have been defined based on geographic regions and businesses, in accordance with the Group organisation structure effective from 1 October 2008, as follows: • Building Solutions - Europe • Building Solutions - North America • Infrastructure Solutions - Nordic. For 2010, the structure will, for the most part, remain as it is today, but as of 1 Jan 2010 the following redefinitions have been implemented: the reporting of the Estonian and Latvian businesses will be split between Building Solutions and Infrastructure Solutions, in contrast to the earlier practice of including everything within Building Solutions - Europe. In addition, the ventilation and ground energy product groups that formed part of Infrastructure Solutions are now classified as belonging to Building Solutions - Europe. The impact of these redefinitions on segment sizes will be small. The new names of the reporting segments are thus: • Building Solutions - Europe • Building Solutions - North America • Infrastructure Solutions. In the future, small sales volumes related to infrastructure products in north-eastern Europe will also be included in the segment Building Solutions - Europe. The size of this business is marginal.
