Chief Executive Officer’s Review

Marc Beuls, Chief Executive comments: “In the fourth quarter Millicom again delivered exceptional growth surpassing what was a record breaking third quarter. Fourth quarter revenues increased by 99% from Q4 2005 to $544m and EBITDA rose by 71% to $229m. In Q4, 3.7 million new subscribers were added, of which 1.9m came through the acquisition of Colombia Movil.

“The very high levels of subscriber intake, 7.4 million for the whole year, went in tandem with increased capex during 2006. Capex for the fourth quarter was $247 million giving a total of $616 million for the year, excluding Pakistan and other discontinued operations. This reflected strong investment in the networks in all our regions, but particularly in Colombia and the Democratic Republic of Congo. The progress made in building a new network in Congo allowed us to launch the Tigo brand this January, and with over 100,000 subscribers today, the first signs for the Congo business are encouraging. We have also launched Tigo in Sri Lanka and expect Tigo to be an important catalyst for this business too.

“Central and South America remain the key drivers of growth reflecting the success of Tigo in the second year after launch. In the fourth quarter, revenues in Central America were up 77% year on year and EBITDA was up 62%. In South America, excluding Colombia where we launched Tigo in November, underlying quarterly revenue growth was 80% and EBITDA growth was 109%. In Africa, with revenues and EBITDA up by 59% and 53%, respectively, we are already seeing the effect of the launch of Tigo and we believe that in the future our African businesses can achieve similar if not higher levels of growth than those we have enjoyed from Latin America. In the fourth quarter, we cleaned up the subscriber base in Tanzania which affected net subscriber intake for the quarter but helped increase ARPUs as these customers were inactive.

“Yesterday we completed the sale of Paktel for an enterprise value of $460 million. The number of subscribers for Pakistan was similar to that for Colombia and as such, the total number of subscribers at year-end has not been materially impacted. We believe our opportunity as the third operator in Colombia is a more attractive prospect and we expect to see Colombia Movil rise towards average group margins in the medium term. The current and prior year results have been presented to show the continuing businesses separately by segregating the discontinued operations. We have also merged the South Asia and South East Asia clusters into one Asian operation.”
