UPONOR NEWS RELEASE For Immediate Release Dec. 16, 2008 Contact: Ingrid Mattsson Brand Management Senior Manager (800) 321-4739, ext. 4249 ingrid.mattsson@uponor-usa.com Jyri Luomakoski Appointed President and CEO of Uponor On Dec. 16, Uponor Corporation’s Board of Directors appointed CFO and Deputy CEO Jyri Luomakoski, MBA, President and CEO of the Uponor Group and its parent company. Luomakoski has acted as CEO on an interim basis since Oct. 27, 2008, when the previous CEO Jan Lång left the company. Jyri Luomakoski has served Uponor since 1996, most recently as CFO and Deputy CEO. For more than four years, he has also been responsible for the company's municipal business in North and South America as well as in the United Kingdom and Ireland. Uponor’s Board initiated the search for a new CEO, assisted by an external consultant, in August, when the previous CEO announced his resignation. The extensive search covered both internal and external candidates. “We weighed between several strong candidates with a diverse background and experiences, and reached a unanimous decision,” says Jari Paasikivi, Chairman of the Board. “Jyri Luomakoski’s international management experience spans over a period of 20 years. He has served Uponor during the past two CEOs, and has gained a versatile experience from the company’s business during its different phases.                   He states other factors that contributed to the decision include the fact that Luomakoski has a broad network of contacts in the different stakeholder groups of the company, and he has a firm support within the Board as well as amongst his colleagues, which allows him a good platform to bring the company forward during these challenging times. As an additional bonus, Paasikivi noted the fact that Luomakoski is centrally involved in current development initiatives of the company, which naturally makes it possible to continue with the renewal of the company and its development initiatives. Luomakoski will, for the time being, also continue as CFO. Changes in the Finance and Administration function management will be announced separately.
