The acquisition price will be paid on a deferred basis, being settled in installments up to the 36th month from the closing, in addition to a variable contingent installment (earn-out) to be determined based on the performance of CURA’s assets at the end of this period. The acquisition price was established assuming zero debt in CURA.

The effective implementation of the Transaction is subject to compliance with the usual precedent conditions for this type of operation, including approval by CADE – Administrative Council for Economic Defense and the implementation of a corporate restructuring involving CURA.

The Company will keep its shareholders and the market informed about the Transaction.
