Millicom receives a 24% stake in leading African towers company, Helios Towers Africa

Stockholm, 07 October, 2015 - Millicom and Helios Towers Africa (“HTA”), one of
the leading, independent telecommunications towers companies in Africa,
today announced that Millicom will own 24% of shares in HTA on a fully diluted
basis following a shareholding reorganisation.
As a result of the reorganisation, Millicom will exchange shares which were
previously held in HTA’s tower companies in Ghana, DRC and Tanzania, into shares
in HTA’s parent company.

This transaction will simplify the share ownership structure of HTA, align
interest among shareholders and move Millicom’s shareholding to the parent HTA
company. The transaction does not change access to commercially sensitive
information, which is held exclusively by HTA.

In 2010, HTA acquired, through its different operating companies, a portfolio of
2,450 Millicom-owned towers in Ghana, DRC and Tanzania. At that time, Millicom
retained equity stakes in the individual tower companies. These equity positions
are now being exchanged for shares in HTA.

HTA recently raised US$363 million in new equity from existing and new
shareholders to fund acquisitions and new growth in existing markets. The share
exchange is being undertaken at the same valuation as the funding round.
