Marc Beuls, Millicom’s President and Chief Executive Officer stated: “Millicom had a strong year with increasing growth in subscribers quarter on quarter and total growth in revenues for the year of 44%. Today Millicom has reached a total of 8 million subscribers across its operations. This excellent momentum has been created by a combination of additional investment in GSM and price elasticity in our main markets. In 2004 Millicom rolled out GSM across Central and South America and we have rebranded our GSM offering under the Tigo brand. Tigo has enabled Millicom to attract higher spending customers, particularly in Central America, which is our largest region in terms of revenues. In November we launched a GSM network in Pakistan leading to rapid growth, so that by the year end we had more than one million customers in this market and Paktel has added in excess of 275,000 new GSM customers to date. The other key driver to growth in 2004 has been the price elasticity we experienced following tariff reductions for customers, particularly in Vietnam, which have driven minutes of use for our existing customers, as well as enabling us to penetrate these markets more rapidly as cellular services become more affordable. “This strong growth was achieved whilst operating at an annual EBITDA margin of just below 50%. The margin in the fourth quarter of 48% was impacted by the launch of the GSM service by Paktel in Pakistan. It will take Paktel more than two years to reach the margins it was experiencing prior to the launch of GSM. This will erode Millicom’s overall margin somewhat over that period of time. “In December 2004 and January 2005 Millicom successfully raised and settled some $400 million, split evenly between equity and convertible debt, and the proceeds of this will be used primarily for funding our businesses in Vietnam and Pakistan. Negotiations for an extension of our co-operation with VMS in Vietnam are ongoing and a decision on the future of the co-operation is expected in the second quarter. In Pakistan, Millicom extended Paktel’s license and is waiting to be offered formal terms by the regulator to extend Pakcom’s license.”
