Patrick Drahi's group is preparing to sell a stake in its fiber optic network in Portugal, valued between 4.7 and 7 billion euros, enough to pay off a little more debt.Selling non-strategic assets to reduce its estimated debt to 30 billion euros at the end of October, strengthening its balance sheet but also in view of auctions on 5G frequencies is the strategy of Altice applied since the first half of 2018. After having sold pylon operations in France, Portugal and the Dominican Republic for more than 2.5 billion euros or a part of its SFR FTTH network for 1.8 billion euros last November, Altice will sell a participation in its fiber optic network in Portugal, revealed yesterday AFP via a source familiar with the matter, confirming at the same time a Reuters information earlier this month, according to which Altice Europe would have appealed to the bank Lazard to "survey potential candidates, including US funds KKR and Morgan Stanley Infrastructure Partners".According to AFP, "the partial sale process started a few weeks ago, and the first official offers are expected around mid-March". Among the nominees in the running, Macquarie, Blackstone, Digital Bridge, Cellnex and Stonepeak Infrastructure would also be added. It remains to be seen how high the winning fund showed to capital.
