The Finnish Competition and Consumer Authority proposes to the Market Court
that the joint venture plan between Uponor and KWH Group be not approved

Uponor Corporation has today received notice from the Finnish Competition and
Consumer Authority that it proposes to the Market Court that the joint venture
plan between Uponor and KWH Group Oy shall not be approved. The plan consists
of merging the infrastructure solutions businesses of both companies into a
jointly owned enterprise.

Against the view of Uponor and KWH, the Competition and Consumer Authority
considers that the transaction potentially leads to a significant impediment of
competition in the markets for infrastructure products.

Uponor and KWH will familiarise themselves with the proposal and consider a
further course of action.

The companies have the right to file their defence for the case at the Market
Court and the Market Court shall give its decision by 25 May 2013.
