**Item 1** 

**Millicom completes upsized reopening of $87.5 million of 7.375% Senior Notes Due 2032**

**Luxembourg, April 14, 2026** – Millicom International Cellular S.A. ("**Millicom**") (NASDAQ US (TIGO)) today completed an $87.5 million aggregate principal amount reopening of its 7.375% Senior Notes due 2032 (the "**Additional Notes**") in a Regulation S only private placement that is exempt from the registration requirements of the U.S. Securities Act of 1933, as amended (the "**Securities Act**") to Banco General, S.A. The offering represents an upsize from the $75 million aggregate principal amount of Additional Notes originally priced on April 1, 2026.

Millicom intends to use the net proceeds of the Additional Notes for general corporate purposes, which may include capital expenditures and mergers and acquisitions.

Application has been made for the Additional Notes to be admitted to listing and trading on the Official List of the Luxembourg Stock Exchange and admitted to trading on the Euro MTF market thereof.

The Additional Notes have been offered outside the United States, only to non-U.S. investors pursuant to Regulation S. The Notes will not be registered under the Securities Act or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws.

This press release shall not constitute an offer to sell or a solicitation of an offer to buy any security and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale would be unlawful.

Certain statements included within this press release are "forward-looking statements" within the meaning of the U.S. federal securities laws intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. These forward-looking statements reflect Millicom's intentions, beliefs or current expectations and include, but are not limited to, all statements other than statements of historical facts, including, without limitation, those regarding Millicom's strategy, plans, objectives, goals and targets, including those related to the use of proceeds of the institutional private placement. Millicom's ability to achieve its projected results is dependent on many factors which are outside management's control. Actual results may differ materially from (and be more negative than) those projected or implied in the forward-looking statements. Such forward-looking information involves risks and uncertainties that could significantly affect expected results and is based on certain key assumptions. Accordingly, no assurance can be given that any particular expectation will be met and reliance should not be placed on any forward-looking statement. Additionally, forward-looking statements regarding past trends or activities should not be taken as a representation that such trends or activities will continue in the future. All forward-looking statements included herein are based on information available to Millicom as of the date hereof and the delivery of this document does not imply that the information contained herein is correct as at any time subsequent to the date hereof. Millicom undertakes no obligation to update publicly or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as may be required by applicable law. All subsequent written and oral forward-looking statements attributable to Millicom or persons acting on its behalf are expressly qualified in their entirety by these cautionary statements.
