Chief Executive Officer's Review
Marc Beuls, Chief Executive Officer, comments:  “In the second quarter of 2007,
Millicom delivered another strong set of results. Second quarter revenues
increased by 80%, from $341 million in the second quarter of 2006 to $613
million in the second quarter of 2007, EBITDA rose by 65% to $263 million, and
the Group's margin was 43%.  Overall, average revenues per subscriber (“ARPUs”)
have remained steady despite aggressive price reductions in many countries
during the second quarter, particularly in Africa, to further enhance the
affordability of our products.  Competition in our markets continues to be
strong, and we are facing faster reactions from our competitiors, particularly
in Central America.  We need to remain innovative and a leader in offering value
for money.  We also continually review our subscriber bases to ensure that we
retain high quality customers, which should help to maintain our ARPUs.  

“We have continued to invest in the networks in all our regions as the move to
per second billing is an additional driver of growth and we need additional
network capacity to process this increase in minutes of use. Millicom has
introduced per second billing in most of its markets. In addition, we are
continuing to aggressively expand our networks in Africa and Asia.  Furthermore,
in Colombia there has been a need to extend the geographic coverage of the
network as this operation focuses on growing its subscriber base and improving
its distribution. We reiterate our stated capex target of over $800 million for
the Group for the full year 2007. With investments of $183 million in the first
quarter and an increased level of spending in the second quarter of $208
million, expenditure is following a pattern of increasing capex throughout 2007.

“We continue to grow our subscriber base at a steady rate and today we have 18
million subscribers on our networks. We feel confident that we can maintain the
current rate of approximately 1.5 million net additions each quarter despite an
expected higher than usual churn of customers due to the phasing out of our
legacy TDMA and CDMA networks in Latin America in 2007 and early 2008, which are
still used by nearly one million customers.  We expect that the higher ARPU
customers will be able to afford a GSM handset and will migrate to our GSM
networks.  The low ARPU customers are unlikely to be able to afford the handsets
and, therefore, we will likely lose many of them.  The loss of these customers
will have little impact on revenues because of their low ARPUs, but it is
important to take this action to release spectrum in the 850 and 1900 bands for
3G services which we are planning to launch in our existing spectrum bands based
on our current licenses in Latin America during 2008/9.

“Central and South America continue to be the fastest growing regions having
been the first to launch tigo, aggressively rolling out e-PIN, and now having
the benefit of per second billing. During the first quarter of 2007, we saw
traffic increase by about 25% over two months in Central America which
compensated for the 25% effective tariff reduction as a result of the
introduction of per second billing in early February. In the second quarter, we
saw a continuation of this acceleration in growth in the total number of minutes
in Central America with revenues increasing by 49% during the second quarter of
2007 and EBITDA by 52%.  Different from our experience in South America when we
launched per second billing, subscriber growth has been unusually strong so soon
after the launch which has resulted in slightly lower ARPUs from deeper
penetration. The EBITDA margin remained strong at 53%, reflecting the high level
of on-net traffic that we generate as our market shares have strengthened across
the region. 

“In South America, excluding Colombia Móvil which was acquired in the fourth
quarter of 2006, underlying quarterly year-on-year revenue growth was 58% and
EBITDA growth was 74%. Revenue growth in Paraguay continues to be strong and its
strong EBITDA margin of 53% reflects a number of factors: a strong market share,
a high level of recurring revenue from Value Added Services and the benefits of
per second billing, which are still being harvested 18 months after launch. In
Colombia, progress has been very encouraging and in the second quarter
subscriber intake was 92,805, reflecting our objective to grow Colombia Móvil's
market share quickly by improving the distribution system and marketing of tigo.
An independent report by AC Nielsen dated May 2007, shows that the tigo prepaid
distribution network in terms of points of sale with inventory is now second in
the market. We believe we are quickly closing this gap. The EBITDA margin of
Colombia Móvil continues to exceed our expectations and in the second quarter of
2007 it increased to 25%, up from 21% in the first quarter of 2007 and 16% in
the fourth quarter of 2006.  Some momentum in revenue growth has now been
achieved in Colombia but we expect to see the main benefits in the third quarter
of 2007 and beyond with the implementation of Colombia Móvil's improved
distribution network. 

“In Africa, quarterly revenues and EBITDA were up by 46% and 15% respectively
year-on-year and the EBITDA margin was 31%. We believe that our African
businesses can achieve higher levels of growth as we continue to invest heavily
in expanding the networks. However, the lack of infrastructure in Africa,
particularly the lack of roads and power, brings specific challenges which can
slow down our expansion and increases the operating costs, impacting EBITDA. 
Our aggressive plans to grow the businesses are temporarily impacting
subscribers, revenues and particularly EBITDA in the short-term.  A promotion in
Ghana in the first quarter of 2007 to lower the price of the SIM cards attracted
many new subscribers but caused the number of subscribers to fall in the second
quarter as a proportion of these new subscribers were not viable long-term
customers.  In Senegal, new legislation was introduced that requires us to
register our customers, which significantly impacted new subscriber intake in
May and June, and will continue to dampen growth in the third quarter.  We
expect that subscriber growth will accelerate at the beginning of the fourth
quarter.  Also in Senegal, there were one-off costs of roughly $3 million that
impacted EBITDA.  Furthermore, both Ghana and Tanzania reduced prices
aggressively in the second quarter which temporarily impacted revenues and
EBITDA for this quarter, but should benefit the rest of the year. In the second
quarter we saw the benefits of the actions taken by the new management in
Tanzania and we expect this operation to improve its performance in the future. 
The beneficial effect of the launch of tigo is particularly evident in Chad
which has been Millicom's most successful launch ever.  Good progress is also
being made with the rollout of the network in the DRC.    

“In Asia, we introduced per-second billing in Cambodia in mid-January and tigo
was launched in Sri Lanka in January and in Laos in March, demonstrating the
improved offering that we now have in Asia. Revenues in Sri Lanka were up 61%
versus the second quarter of 2006 reflecting the substantial investments that
have been made in the network in 2006 and early 2007. Overall, Asia reported a
35% growth in revenues, a 44% growth in EBIDTA and a margin of 42%. 

“With growth continuing at a strong pace fuelled by increasing capex across our
markets, we expect 2007 to be another record year for the Group.

“This year's investor visit will be held between 29th October and 1st November
in Colombia. We look forward to showing visitors how succesfully we are
operating in this market only a year after entering the market with tigo.”
