The report, titled "Achieving sustainable growth in a digital world," focuses on the impact of OTT (over-the-top) services on the MENA (Middle East and North Africa) telecoms industry. The authors argue that while most operators in the region have enjoyed a benign environment, digital market dynamics will eventually prevail. They predict that the market in the MENA region will undergo significant changes over the next five years, with ride-sharing and adjacent revenue streams presenting opportunities for local leaders in the OTT space. The report also highlights the importance of improving efficiency and optimizing bad debt in order to achieve sustainable growth. The authors thank colleagues for their support and input, and acknowledge the contributions of Bertrand Grau and Antoine Pradayrol to the 2015 edition of the Exane BNP Paribas - Arthur D. Little joint report.
