Under the agreement, Piraeus, which now holds a 45% stake in Trastor, will acquire an additional stake of 52% in Trastor, it said.

Once concluded, the transaction will trigger a mandatory tender offer by Piraeus to buy the remaining 3% stake in Trastor.

Piraeus Bank CEO Christos Megalou said that the transaction would instantly enhance the bank's fee revenue profile and further bolster its real estate sector know-how.
