Millicom (Tigo) Q4 2023 Earnings Release

Luxembourg, February 27, 2024 – Millicom is pleased to announce its fourth quarter 2023 results. Please find below links to the Q4 2023 Earnings Release and IAS 34 Interim Condensed Consolidated Financial Statements.

Highlights*

• Revenue grew 6.8% driven by Service revenue up 7.7%, reflecting the effect of stronger currencies and organic growth of 3.2%, up from 1.8% in Q3 thanks mostly to large B2B contracts in Panama, as well as faster growth in Colombia and Bolivia.
• Operating profit declined 3.8%, while EBITDA grew 1.6%, and both were impacted by $42 million of one-off severance costs in the quarter.
• Excluding severance and the benefit of stronger currencies, EBITDA grew 5.3% organically, with Colombia up 24.5%, as margins continued to expand in the country.
• Operating cash flow was $294 million in Q4 and $1.3 billion for the full year, up 12.3% organically excluding severance and other one-offs thanks largely to improved performance in our Colombia operation.
• For the full year 2023, Equity free cash flow was negative $18 million¹ and was impacted by $106 million in severance and other one-off costs, as well as increased spectrum renewal and purchase activity.

Millicom Chief Executive Officer Mauricio Ramos commented:

"During Q4, we put in place the last remaining building blocks to position the company to drive a material and sustainable increase in annual equity free cash flow generation beginning in 2024. Specifically:

• we implemented Phase 2 of Project Everest, which we anticipate will drive significantly higher EBITDA from each country and lower centrally-managed costs going forward;
• we acquired 5G spectrum jointly with Telefonica's Colombia subsidiary and we advanced a mobile network combination, marking another important step to optimize our capital investment, improve profitability, and increase free cash flow generation in this country;
• we sustained market leadership and saw encouraging pricing and growth trends in Guatemala, and we started to utilize recently-acquired spectrum to optimize our network investment in that country;
• we maintained our B rating from CDP, demonstrating Millicom’s commitment to climate change mitigation; 
• we launched the Lati monetization process, aimed at optimizing Millicom's investment and capital structure.

As a result of these actions and considering also many other initiatives implemented in recent years, we are well positioned to achieve our target equity free cash flow of around $550 million in 2024.

Finally and on behalf of the board and the entire Tigo team, I wish to express our heartfelt sorrow following the untimely passing of Nicolas Jaeger, our esteemed Board member, colleague, and friend."
