Millicom Chief Executive Officer Marcelo Benitez commented:

"Millicom is becoming a larger, stronger and more cash generative company. Our strategy is to strengthen our leadership positions in Latin America through disciplined organic growth and selective consolidation, while applying a consistent operating model focused on customer value, efficiency and equity free cash flow. Our second-quarter performance demonstrates that this strategy is working: we are growing the underlying business, integrating our expanded portfolio and strengthening our capacity to create sustainable value for our customers and shareholders.

We are also seeing encouraging results from the Millicom playbook in our acquired operations. Ecuador and Uruguay have delivered meaningful improvements in margins and equity free cash flow and are now performing broadly in line with the Millicom average. In Colombia and Chile, the integration and turnaround are progressing well, with early improvements in profitability and cash generation as we approach a more steady state of the operations.

We delivered strong second-quarter financial results. Service revenue reached $2.04 billion, while Adjusted EBITDA exceeded $1.01 billion for the first time in Millicom’s history. Equity free cash flow reached a quarterly record of $327 million.

Our first-half performance, together with the progress of our integrations and improved visibility across the portfolio, gives us increased confidence for the remainder of the year. As a result, we are raising our 2026 equity free cash flow guidance to around $1.1 billion, while lowering the year-end leverage target from approximately 2.5x to below 2.5x.

Reflecting this stronger performance, Millicom's Board of Directors approved an incremental interim dividend of $1.50 per share, payable in two installments of $0.75 per share in January and April 2027. We remain focused on disciplined execution and believe there is significant additional value to unlock."

2026 Financial Targets

Millicom is raising its full-year 2026 EFCF guidance from at least $900 million to around $1.1 billion, while lowering its year-end leverage target from around 2.5x to below 2.5x. These targets include restructuring costs associated with all acquired businesses.
