Revised accounting treatment of Honduras transaction

Stockholm, January 26, 2012 – Millicom International Cellular S.A. (“Millicom”) (Stockholmsbörsen: MIC) announced today that it is restating its full-year financial statements for 2010 as well as its
interim quarterly financial statements for the periods ended September 30, 2010 to September 30, 2011 to reflect a revised accounting treatment of the put option provided to its local partner inthe July 1, 2010 Honduras transaction. The amended accounting treatment of the put option and consequent restatements have no effect on reported revenues, EBITDA, operating cash flow,
dividends and guidance.

On July 1 2010, Millicom reached an agreement with its local partner in Honduras whereby Millicom’s local partner granted Millicom an unconditional call option for a duration of five years
for his 33% stake. At the same time, Millicom granted a put option for the same duration to its local partner, exercisable in the event of a change of control of Millicom or the Honduras
subsidiary. As a result of the transaction, Millicom started to consolidate fully its subsidiary in Honduras.
Following a reassessment of the accounting treatment of the Honduras transaction, Millicom has retroactively recorded a liability for the put option at July 1, 2010 of $737.4m, representing an
estimate of the net present value of the redemption amount of the put option at that date in accordance with IAS 32.23 and a corresponding decrease of shareholder’s equity. Millicom has
also recorded a financial expense/income for each subsequent reported period to reflect the change in value of the put option liability in accordance with IAS 39. Such financial
expense/income has impacted net profit negatively for 2010 by $32m (less than 2% of reported net profit) and positively for the first nine months of 2011 by $50.8m.
There is no change to the economic substance of the put option and accordingly to its fair value,
which is assessed as not material for each of the restated reporting periods. In addition, this does
not impact the full consolidation of Millicom’s Honduras subsidiary from July 1, 2010.

Please find attached unaudited restated historical financial information as of and for the year ended December 31, 2010 as well as for interim periods from September 30, 2010 to September 30, 2011. Millicom expects to publish audited restated financial statements for 2010 and 2011 on March 2, 2012 in its 2011 Annual Report on Form 20-F.
