Millicom reported a strong first half of 2025 driven by infrastructure disposals and cost savings while revenue was weighed down by currency moves. Group revenue fell 6.8% to $2,746 million in H1 2025, largely because of weaker currencies in Bolivia, Colombia and Paraguay. Adjusted EBITDA for H1 was $1,277 million and Q2 record Adjusted EBITDA reached $641 million with a 46.7% margin. A partial closing of the LATI infrastructure sale generated a $604 million gain and about $546 million net proceeds to date.
Net profit attributable to owners was $869 million ($5.17 per share) in H1 2025 versus $170 million a year earlier, reflecting the infrastructure gain and operating cost reductions. Management reiterated a 2025 equity free cash flow target of around $750 million and a year-end leverage target below 2.5x; reported leverage was 2.18x after transaction proceeds. The Group adopted Amendments to IAS 21 affecting Bolivia, where an average exchange rate implied a 55% devaluation impact in Q2.
