Millicom enters into put and call agreement with Guatemala partner

•   Millicom and its partner in Guatemala have entered into a put and call
agreement

•   Millicom ownership in Tigo Guatemala remains unchanged at 55% and both
partners will work together to further develop the business to the benefit of
all customers

Stockholm, January 16, 2014 - Millicom, the international telecommunications and
media company (Stockholmsbörsen: MIC) and its partner in Tigo Guatemala have
strengthened their partnership by entering into a put and call agreement.
Under the agreement, Millicom’s local partner in Guatemala, Miffin Associates
Corp., has granted Millicom an unconditional call option for its 45% stake with
a minimum term of two years. In return, Millicom has granted its partner a put
option for the same duration, exercisable in the event Millicom sells its
interest in Tigo Guatemala or undergoes a change of control.

As a result, Millicom will fully consolidate the operation in Guatemala from
January 1, 2014. Previously, the accounts of the Guatemala business were
proportionately consolidated.

Commenting on the agreement today, Millicom President & CEO, Hans-Holger
Albrecht said:

“Over the years, we have worked very successfully with our partner to grow the
company into the most successful mobile player in Guatemala. Today’s agreement
strengthens our partnership with Miffin Associates Corp to the benefit of Tigo
Guatemala’s people and its customers. This new structure will enable us and our
partner to take Tigo Guatemala to new heights in the years to come.”

While the agreement has no impact on Millicom’s reported normalized net profit
or on Millicom’s overall exposure to Guatemala, the pro forma impact of this
change on the Group financial statements for the nine months ended September 30,
2013 is an increase in reported revenues, EBITDA and FCF by 10%, 14% and 16%
respectively.

We will provide with our FY results on February 11, 2014 a pro forma non audited
P&L for the past years and quarters for comparability purposes.
