LEMMINKÄINEN: OLKILUOTO CONCRETE EXCEEDS ALL QUALITY REQUIREMENTS

According to claims in the media, the ready-mix concrete produced by
Lemminkäinen's subsidiary Forssan Betoni Oy for the Olkiluoto nuclear power plant
project does not meet the quality requirements set for it.

Lemminkäinen refutes these claims as being completely untrue, and states that the
Olkiluoto concrete deliveries exceed all the standards and other quality
requirements pertaining to them. The confidentiality agreement signed by the
company prevents it from commenting any further on this matter.
