Under Marafih’s guidance, Qatar Telecom (Qtel) is continuing its rapid expansion and recently raised its stake in Tunisian operator Tunisiana to 90 per cent. The firm also successfully issued a $1 billion 10-year bond in December 2012. A GSMA board member, Marafih has overseen Qtel’s growth from a single-country operator to having a presence in 17 countries.
