The agreement provides for a consideration as well as an enterprise value of about 140 million US dollars (equivalent to approximately 120 million euros ^[3]) subject to adjustments customary for these types of transactions, with an impact on Group net financial debt of approximately 180 million US dollars ^[4] (equivalent to around 155 million euros ^[3]).

Through the transaction announced today, the Enel Group will enter these states for the first time.

Following the closing of the transaction, a positive net effect of approximately 20 million US dollars per year is estimated on the Enel Group´s consolidated ordinary EBITDA.
