Metso's patent held invalid and earlier favorable decision reversed by Court of Appeals in a US patent infringement case

The United States Court of Appeals for the Federal Circuit has given an
unfavorable decision to Metso holding Metso's patent invalid with respect to the
issues subject to the lawsuit Metso has carried out against Powerscreen
International Distribution Ltd (today known as Terex GB Ltd), Terex Corporation,
Emerald Equipment Systems, Inc. et al. The case involves the Metso's lateral
folding conveyor patent rights related to mobile crushing and screening plants.
The Court of Appeals has reversed the favorable decisions to Metso given earlier
by the United States District Court for the Eastern District of New York in the
case (see Metso's stock exchange releases December 7, 2010 and December
12, 2011).

Metso will seek reversal of this Court of Appeals' decision by motions and, as
necessary, by further appeal. The final outcome of the lawsuit would be expected
within 2014.

Metso has not booked any compensation in its financial results based on the
earlier decisions related to this case; and will do so, if any, only when the
final outcome of the lawsuit is clear, earliest in 2014.
