Explanatory Note

This Amendment No. 15 (“Amendment No. 15”) to Schedule 13D relates to the Common Shares, par value $1.50 per share (the “Common Shares”), of Millicom International Cellular S.A., a Luxembourg company (the “Issuer”), and amends and supplements the initial statement on Schedule 13D filed on February 24, 2023, as amended by Amendment No. 1 to the Schedule 13D filed on March 28, 2023, Amendment No. 2 to the Schedule 13D filed on April 26, 2023, Amendment No. 3 to the Schedule 13D filed on May 12, 2023, Amendment No. 4 to the Schedule 13D filed on May 25, 2023, Amendment No. 5 to the Schedule 13D filed on June 2, 2023, Amendment No. 6 to the Schedule 13D filed on July 24, 2023, Amendment No. 7 to the Schedule 13D filed on August 24, 2023, Amendment No. 8 to the Schedule 13D filed on October 2, 2023, Amendment No. 9 to the Schedule 13D filed on November 8, 2023, Amendment No. 10 to the Schedule 13D filed on January 17, 2024, Amendment No. 11 to the Schedule 13D filed on May 23, 2024, Amendment No. 12 to the Schedule 13D filed on July 3, 2024, Amendment No 13. to the Schedule 13D filed on July 22, 2024 and Amendment No. 14 to the Schedule 13D filed on August 2, 2024 (as so amended, the “Schedule 13D”). Capitalized terms used but not defined in this Amendment No. 15 shall have the same meanings ascribed to them in the Schedule 13D.

Atlas’ tender offer for all of the Issuer’s outstanding Common Shares and SDRs referred to in this Schedule 13D commenced on July 1, 2024. This Schedule 13D is for informational purposes only and is neither an offer to purchase nor a solicitation of an offer to sell any securities of the Issuer or any other securities, nor is it a substitute for the Tender Offer Statement and Rule 13e-3 Transaction Statement, including the Offer to Purchase, Letter of Transmittal and related documents, that Atlas has filed under cover of Schedule TO with the U.S. Securities and Exchange Commission (the “SEC”), and the Solicitation/Recommendation Statement that the Issuer has filed on Schedule 14D-9 with the SEC. The US Offer is only being made pursuant to the Offer to Purchase, the Letter of Transmittal and related documents filed as a part of the Tender Offer Statement and Rule 13e-3 Transaction Statement filed under cover of Schedule TO. The Tender Offer Statement and Rule 13e-3 Transaction Statement (including the Offer to Purchase, the related Letter of Transmittal and certain other offer documents) and the Solicitation/Recommendation Statement on Schedule 14D-9 of the Issuer contain important information that US Holders of Common Shares should consider before making any decision with respect to the tender offer. US Holders of Common Shares are urged to read these documents carefully. Investors and security holders may obtain a free copy of these statements and other documents filed with the SEC at the website maintained by the SEC at www.sec.gov, or by directing such requests to the Information Agent for the tender offer that is named in the Tender Offer Statement and Rule 13e-3 Transaction Statement filed under cover of Schedule TO.

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 of the Schedule 13D is hereby amended and supplemented as follows:

The information set forth in Item 4 of the Schedule 13D is incorporated by reference in its entirety into this Item 3. Purchaser has accepted for payment, and expects to pay around September 2, 2024, for all Shares and validly tendered (and not validly withdrawn) during the period of the Offer. The aggregate purchase price payable by Purchaser upon the consummation of the Offers will be approximately $496,186,457.75 for 19,269,377 Shares and will be sourced by drawing down from the Long-Term Financing (as defined in the Offer to Purchase).

The information disclosed in this Item 3 does not purport to be complete and is qualified in its entirety by reference to the Senior Facilities Agreement and the Senior Facilities Agreement Amendment Letter, copies of which is filed as exhibits hereto and are incorporated herein by reference in their entirety.

Item 4. Purpose of Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following:

On August 22, 2024, the Offers and the withdrawal rights expired as scheduled at one minute after 10:59 a.m. EST or one minute after 4:59 p.m. CEST and were not further extended. As of such time all remaining conditions to the Offers were satisfied and the Offers were completed. Broadridge Corporate Issuer Solutions, LLC, acting as the US Tender Agent and Handelsbanken, acting as the Swedish Settlement Agent, have advised Purchaser that a total of 19,269,377 Shares were validly tendered and not properly withdrawn, representing approximately 11.25% of the outstanding Shares (based on 172,096,305 Shares outstanding less 789,807 Shares held in treasury by Millicom as of July 30, as disclosed by Millicom on such date under the “Stock Information” section of Millicom’s website). Of the Shares tendered, 2,230,932 Common Shares were tendered pursuant to the US Offer and 17,038,445 SDRs were tendered pursuant to the Swedish Offer. All Shares that were validly tendered and not properly withdrawn pursuant to the Offers have been accepted for payment by Purchaser. Together with Purchaser’s 49,966,734 Shares held prior to the Offers, Purchaser will now hold 69,236,111 Shares, representing approximately 40.42% of the outstanding Shares. Settlement for the Shares tendered in the Offers is expected to be initiated in accordance with the terms of the Offers around September 2, 2024.

Item 5. Interest in Securities of the Issuer.

Items 5(a)-(c) of the Schedule 13D are hereby amended and restated as follows:

(a) and (b) The percentage of beneficial ownership in this Schedule 13D is based on 171,306,498 Common Shares outstanding as of July 30, 2024 (172,096,305 Common Shares outstanding, less 789,807 Common Shares held in treasury, as set forth in the last relevant update available on the date hereof in the “Stock Information” section of the Issuer’s website).

The aggregate number and percentage of Common Shares beneficially owned by each Reporting Person and, for each Reporting Person, the number of shares as to which there is sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or to direct the disposition, or shared power to dispose or to direct the disposition are set forth on rows 7 through 11 and row 13 of the cover pages of this Schedule 13D and are incorporated herein by reference.

As of August 22, 2024, Atlas beneficially owned 67,005,179 SDRs, which may be exchanged for Common Shares on a one-for-one basis and 2,230,932 Common Shares. Settlement for the Shares tendered in the Offers is expected to be initiated in accordance with the terms of the Offers around September 2, 2024.

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any Reporting Person (other than Atlas to the extent it directly holds the securities reported herein) is the beneficial owner of the Common Shares referred to herein for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, or for any other purpose and each of the Reporting Persons expressly disclaims beneficial ownership of such shares.
