Altice said on Thursday Chief Executive Michel Combes had resigned with founder Patrick Drahi returning as president.

Shares in the Amsterdam-based company, whose debt burden reached 49.557 billion euros (43.86 billion pounds) by the end of the third quarter, have lost around a third of their value since Altice said earlier this month that it lost about 75,000 broadband customers in France, its biggest market, in the third quarter.
