Finnish national telecoms carrier Sonera Oy said yesterday it has decided to reduce its stake in the merging IT services companies Tieto Corp (from Finland) and Enator AB (from Sweden) by 50% over the next two years. Sonera said that, on the basis of its current holdings, it would end up with a 20% in Tietoenator, whose formation was announced earlier this year (CI No 3,611). The company announced yesterday, however, that in talks with the Finnish competition watchdog it had agreed to reduce its overall stake to 10% in order to insure that the merger of Tieto Corp and Enator AB can proceed.
