MTN Group is considering the sale of its stake in Botswana’s largest wireless carrier, according to people familiar with the matter, as CEO Rob Shuter seeks to reduce the number of countries in which the company operates. A disposal of the interest in Botswana’s Mascom could generate as much as R2.5-billion, said the people, who asked not to be identified because the sale process is ongoing and nothing has been publicly disclosed. While Shuter initiated a review of MTN’s then-22 markets a year ago, the Johannesburg-based company has to date only completed the sale of its Cyprus operation.
