About Helios Towers

·   Helios Towers is a leading independent telecommunications infrastructure company, having established one of the most extensive tower portfolios across Africa. It builds, owns and operates telecom passive infrastructure, providing services to mobile network operators.

·   Helios Towers owns and operates telecommunication tower sites in Tanzania, Democratic Republic of Congo, Congo Brazzaville, Ghana, South Africa, Senegal, Madagascar and Malawi. Following recent acquisition agreements and subject to regulatory approval, Helios Towers expects to establish a presence in two new markets across Africa and the Middle-East. Including these acquisitions and committed BTS, the Group's total site count is expected to increase from over 10,000 towers to over 14,000.

·   Helios Towers pioneered the model in Africa of buying towers that were held by single operators and providing services utilising the tower infrastructure to the seller and other operators. This allows wireless operators to outsource non-core tower-related activities, enabling them to focus their capital and managerial resources on providing higher quality services more cost-effectively.
