As previously announced, the consideration for the Transaction is €9 million, of which €4 million at closing, €2 million deposited in an escrow account, released according to the contractual terms over 24 months, and €3 million through the issue of a maximum of 535,714 new Mare Group ordinary shares, valued at €5.60 each, subscribed by CTM S.r.l. (“CTM”) through a capital increase reserved to it, and subject to a 24-month lock-up from the delivery date.
