Stock Exchange release 10 September 2008 19:00 Uponor closes Canadian manufacturing facility Uponor announced today a decision to close its Canadian manufacturing facility in Saint John, New Brunswick, effective 10 Sept. 2008. The closing is part of the initiative to reduce costs and align expenses to the low activity level in the building and construction industry. On 12 August, Uponor announced a global programme that targets structural cost reductions in the range of EUR 30 million, effective in 2009. The planned actions are likely to affect more than 200 employees corporate-wide. Approximately 80 employees are influenced by the closure in St. John. Uponor is working with them during this transition by offering outplacement services and severance packages. There will be new recruitments in the Apple Valley, Minnesota factory later on, which will somewhat impact the total personnel reduction. Closing the St. John facility allows Uponor to improve the overall operational effectiveness in response to the marketplace. Despite the difficult economic environment, Uponor is also taking advantage of opportunities and actively focusing on its strategic growth initiatives in North America, such as new product development, investments in the Apple Valley manufacturing facility, and new distribution centre.
