Metso’s American Depositary Share trading has moved to the over-the-counter (OTC) market in the United States

Metso Corporation’s American Depositary Shares (ADSs) have been delisted from the New York Stock Exchange effective today. Company’s ADSs continue to trade on the OTC market under the ticker symbol MXCYY.

Metso expects to complete the delisting and deregistration process during 2007. Metso intends to file a Form 15F with the SEC on September 17 to terminate its Section 12(g) registration and Section 13(a) and Section 15(d) reporting obligations under the Exchange Act. Upon the filing of Form 15F a 90-day waiting period is triggered during which time the SEC could object to the filing. At the end of the 90-day waiting period, such suspension becomes a termination, provided that the SEC does not raise objections or the Form 15F is not earlier withdrawn by Metso. Metso reserves the right to delay the filing of the Form 15F or withdraw the Form 15F for any reason prior to its effectiveness.
