On May 31, 2013, the Board of Directors of Metso Corporation approved a demerger plan, which was registered with the Finnish Trade Register on June 6, 2013. Pursuant to the demerger plan, Metso Corporation will demerge in a partial demerger to the effect that all such assets, debts and liabilities of Metso Corporation that relate to Metso Corporation's Pulp, Paper and Power businesses (the "PPP Business") will transfer, without liquidation, to a company to be incorporated in the demerger (such company, "Valmet Corporation") in the manner set forth in more detail in the demerger plan.

The purpose of the demerger is to execute the separation of Metso Corporation's businesses to the effect that the PPP Business is separated to Valmet Corporation and Metso Corporation's other businesses, including, among others, the Mining and Construction as well as the Automation businesses, will remain with Metso Corporation.

The Board of Directors of Metso Corporation proposes that the General Meeting approves the demerger plan and decides on the partial demerger of Metso Corporation in accordance with the demerger plan.
