French mobile network operators SFR and Bouygues Telecom have put their tower joint venture up for sale.

French newspaper Le Monde reported that the two companies, which each own 50 percent of the JV, have agreed to sell the unit.

The unit, called Infracos, manages around 3,500 rooftop terraces, pylons, and other high mobile network points in rural areas of France.

The publication suggests Infracos, formed in 2014, could command between €800 million ($900m) to €1 billion ($1.12bn), based on the understanding that a roof terrace or a pylon could be worth €300,000 ($337,000) individually.

Infrastructure investment funds could reportedly be interested in acquiring the JV, with both SFR and Bouygues Telecom becoming long-term tenants of the infrastructure.

SFR’s parent company Altice is looking to ease its overall debt, which currently sits at €15.5bn.

In February, Altice France, along with most of its creditors, reached an agreement to slash the company’s debt by €8.6bn ($9.67bn).

The telco, owned by French billionaire Patrick Drahi, has sold a number of key assets in the last couple of years, including its 24.5 percent stake in UK telecoms giant BT to Bharti Airtel, in a deal estimated to be worth about $4 billion at the time.

Drahi only increased Altice UK’s stake in BT to 24.5 percent in May 2023, and even had plans to increase it to nearly 30 percent.

However, after years of acquisitions, the company has been looking to shift assets in order to pay down its mounting debt.

The company is open to selling its telecoms business and recently spun off its French data center assets, forming a new company with more than 250 facilities in France, which was then sold to Morgan Stanley.

Altice has been in talks over a deal to sell its Portuguese mobile unit, but ended talks with Saudi Telecom Group (STC) in June.

The Portuguese unit of Altice has also been separately looking to sell off its data center unit.
