The pro forma numbers exclude Vietnam, where our BCC ended in May and include Millicom’s joint venture in Honduras with a percentage ownership of 66.67% to reflect the increase in ownership from 50% in May 2005. Pro forma EBITDA was up by 6% from the second quarter of 2005. The main driver in revenue growth was a 13% increase in revenues in Central America, 10% in South America and the 5% growth in revenues in Africa, which continue to be our star performers.” “The Latin American market has seen a strong acceleration in subscriber growth since the launch of GSM and the Tigo brand in 2004, and this has continued to gather momentum as Millicom continues to take market share in Central America. In Africa, Ghana and Senegal were particularly strong markets and Tanzania is beginning to improve its performance. Millicom has started operating in two new markets, launching operations in Chad in October and purchasing the Oasis business in Congo. Together these two countries add some 70 million new people under license, replacing the potential new subscribers lost with the end of our BCC in Vietnam.” “Millicom is currently negotiating the sale of its share in Pakcom, its second operation in Pakistan. It is interesting to note that Millicom’s growth would have been even higher without Pakcom. Millicom has decided to concentrate its investment in Pakistan into its Paktel business and in total, since 2002, Millicom has committed $250 million of investment, excluding the license fee. Paktel is growing strongly and by the end of the quarter the business had 945,000 subscribers.” CONTACTS: Marc Beuls Telephone: +352 27 759 327 President and Chief Executive Officer Millicom International Cellular S.A., Luxembourg Andrew Best Telephone: +44 20 7321 5022 Investor Relations Shared Value Ltd, London Visit our web site at www.millicom.com Please see the attached document for the full press release.
