NRJ Group SA (ENXTPA:NRG) has put its towers arm Towercast S.A. up for sale. “Towercast is very profitable and could be worth more than €300 million. Towercast is not in our core business and its membership of the NRJ group is even today a handicap to attract new customers”, said Jean-Paul Baudecroux, the Chief Executive Officer of NRJ Group.
