1. OUTCOME OF THE FIRST EXTRAORDINARY MEETING OF SHAREHOLDERS

The EGM was initially convened to be held on Monday, January 24, 2022, at 4:00pm CET (the "First EGM"). As the quorum required pursuant to article 450-3 of the law of 10 August 1915 on commercial companies, as amended, and article 21 of the Company's articles of association was not met at the First EGM, the EGM is hereby reconvened in accordance with applicable law pursuant to the terms of this notice (see sections II-IX below).

It is noted that at the First EGM, 44,564,846 shares of the Company were represented constituting approximately 44.48 per cent of the Company's share capital excluding treasury shares (as opposed to the required fifty per cent). Out of the shares represented, approximately 99% per cent submitted their proxy to vote in favor of all three items set forth below in section III, including the increase of the authorized share capital , which means that all proposals would have been approved if quorum had been reached. As the required quorum was not met at the First EGM, the EGM needs to be reconvened as per the sections below.

1. NOTICE (FOR THE RECONVENED EXTRAORDINARY MEETING OF SHAREHOLDERS)

The extraordinary general meeting ("EGM") of the shareholders of MILLICOM INTERNATIONAL CELLULAR S.A. ("Millicom" or the "Company") is hereby reconvened to be held virtually (i.e., without a physical presence) on Monday, February 28, 2022, at 4:00pm Central European Time("CET").

The Company continues to monitor developments regarding the coronavirus disease (COVID-19) and related instructions from the Luxembourg Ministry of Health and other competent authorities in and outside of Luxembourg. Due to these circumstances, Millicom is taking precautionary measures to limit the exposure for its employees, shareholders and stakeholders, and the Board of Directors (the "Board"). The Board resolved to hold the EGM without a physical presence, in accordance with Luxembourg law. The shareholders are therefore hereby informed that it will not be possible to attend the EGM physically. Shareholders are in this context reminded that they may exercise their shareholders' rights at the EGM solely by voting by proxy as further specified below.

To vote by proxy, please follow the instructions in section V: "Right to participate at the EGM".

Proxies submitted to the First EGM (covering as well any adjourned or reconvened meeting with the same agenda such as the EGM) will be automatically counted at the EGM, as long as the shareholder or SDR holder
