Stockholm, February 5, 2013 – Millicom International Cellular S.A. (“Millicom”)
(Stockholmsbörsen: MIC) announces today that it has entered into exclusive
negotiations with EPM regarding the possible combination of their Colombian
telecom operations.
EPM (Empresas Públicas de Medellín) is an industrial and commercial conglomerate
owned by the municipality of Medellín. It is the largest shareholder of UNE EPM
Telecomunicaciones (‘UNE’) which provides cable TV and fixed telephony services
across the region encompassing Medellín, the second largest city in Colombia.
UNE owns 25% of Colombia Móvil (‘Tigo Colombia’), in which Millicom owns 50% and
one share.

The purpose of the negotiation is to evaluate the possibility of a merger
between the holding company that owns 50% of Colombia Móvil- Tigo- and UNE EPM
to create a leading integrated telecommunication operator in Colombia.

Millicom and EPM have partnered successfully for the past six years as we
jointly own Tigo Colombia together with ETB (Empresa de Telecomunicaciones de
Bogotá) from Bogotá. More recently, UNE has started offering mobile services, in
part through a roaming agreement with Tigo Colombia. The market dynamics for
fixed and mobile integration create potential to offer best quality services to
customers, notably digital services. As a consequence, both parties agree that
it is the right time to consider integration of the businesses, with a
shareholders’ agreement similar to what has been successfully governing the
relationship over the past six years.

Hans-Holger Albrecht, President and CEO for Millicom, commented:

“We are pleased to have reached an advanced stage in our discussions with EPM.
It underlines a few key principles we are working with at Millicom:

Millicom values its successful partnership with EPM. The combination of a strong
local partner with the international expertise of Millicom has provided a solid
model in the past and will be even more important for the future. It is a
trustful and good working relationship.

Secondly, Millicom strongly believes in a customer centric approach; to offer
customers the best digital services on all devices and from all locations. The
strong combination of mobile and fixed businesses will allow us to move even
faster in this direction to the benefit of our customers. We will be able to
offer the most entertaining and most innovative products in the future.

And finally, we will be investing into a country we know very well which is
growing at a fast rate.

So all in all, it is a compelling opportunity that we want to pursue further to
enhance shareholder value.”

Juan Esteban Calle, CEO of EPM, further added:

“We are optimistic about the conversations with Millicom. It is our fiduciary
duty to explore alternatives that will lead UNE EPM to improve its competitive
position in the telecommunications industry, a sector we consider strategic for
the competitiveness of Medellin, Antioquia and Colombia. We believe that our
markets and strengths are naturally complementary and there is a fit in
corporate values such as transparency, social responsibility and customer
orientation.

A stronger position in the telecommunications market would accelerate the
implementation of our strategy to become the partners of choice of all Colombian
regions in their quest for better services for their citizens and more developed
and equitable territories.”

UNE and Tigo Colombia product portfolios and geographic presences are very
complementary. The contemplated transaction would be a merger of equals and
would be subject to regulatory approval. Under the terms provisionally discussed
between the two parties, Millicom and EPM would contribute their respective
telecommunication businesses in Colombia into a newly created entity. Should an
agreement be reached, Millicom does not anticipate that its consolidated Net
Debt to EBITDA ratio will exceed 1.5x (post-transaction).

The discussions are expected to conclude during the first half of 2013.
