A NEW STRUCTURE TO SEIZE NEW OPPORTUNITIES

Stockholm, February 1, 2012 – Millicom International Cellular S.A. (“Millicom”)
(Stockholmsbörsen: MIC) announces today the introduction of a new structure
which will be implemented throughout 2012.  There are 3 key components to it:
(1) In-Market Organizations, (2) Global Categories and (3) Global Support
Functions.  This new organization structure is designed to support Millicom’s
strategic goals to accelerate the development of new products and categories,
deepen its consumer understanding skills and to bring innovation to its
go-to-market strategies, while continuously focusing on increasing efficiency.
 The head office of Millicom will remain in Luxembourg, while some categories
and functions will be operated from Miami.

Millicom will continue to report its results by region, namely: Central America,
South America and Africa.  Millicom intends to increase, over time, the level of
disclosure by category: Communication, Information, Entertainment, Solutions and
Mobile Financial Services (MFS).

Mario Zanotti, formerly Chief Officer Latin America, has been appointed COO
Categories and Global Sourcing, responsible for the Communication, Information,
Entertainment and Solutions categories as well as the group Technology and
Supply Chain functions.  Regis Romero, formerly Chief Officer Africa, has been
appointed COO Global Markets.  He will be in charge of operations in all
markets, including the development of the Home segment, which includes broadband
internet and cable TV.  The MFS category, which encompasses cash transfer
services and other banking activities, will be managed by François-Xavier Roger,
Chief Financial Officer, who will continue to head the Global Finance function.
 The Global HR function will be headed by Jo Leclère, Chief HR Officer.  These
executives, together with Mikael Grahne, President and Chief Executive Officer,
will form the Executive Committee. 

Mikael Grahne, CEO, commented: “In a fast-moving industry, we have consistently
innovated, differentiating ourselves from our global competitors. While we have
grown rapidly, our business has become more complex, presenting many
opportunities and exciting challenges. Non voice products already account for
28% of our revenues. We expect them to generate more than half of our revenues
in a few years. This evolution requires that we accelerate the development of
new products and categories, deepen our consumer understanding skills, and
innovate in our go-to-market strategies. The new structure will ensure that we
have the best possible mix of local experience and global expertise.”
