ICTSI had earlier offered to buy out other shareholders in the Singapore-listed port operator at S$1.20 a share, but decided to withdraw its offer after Mitsui made a superior bid at S$1.40 a share.
The Philippine port company acquired its 16.9% stake in Portek at prices ranging from S$1.19 and S$1.20, which is around 11% lower than the price offered by Mitsui.
