Millicom Chief Executive Officer Marcelo Benitez commented:

"We are off to a strong start in 2026, with solid operational execution and important progress on the strategic initiatives that will shape the future of Millicom. During the quarter, we strengthened our position in Colombia through the acquisition of EPM's 50% stake in Tigo UNE and Telefónica's majority stake in Coltel, which we are now fully consolidating in our results. Shortly after quarter-end, we also acquired the remaining stake in Coltel from La Nación de Colombia. Together, these steps give us greater scale, stronger network assets, and a broader customer base in one of our most important markets.

Led by NJJ, we began to apply the Millicom playbook in Chile, following the acquisition of Telefónica Chile. While it is still early, the new leadership team has already taken decisive action to simplify the commercial offer, stabilize ARPU, reduce leverage, and resize the organization.

Operationally, our underlying business continues to perform well. In Mobile, our prepaid-to-postpaid migration strategy continues to gain traction, supporting ARPU growth and service revenue momentum.

Financially, Service Revenue grew 4.9% organically to USD $2 billion while Adjusted EBITDA reached $857 million, with a reported margin of 43.2%, despite initial Coltel integration and restructuring costs. Equity free cash flow was $225 million for the quarter improving $90 million year-on-year when excluding last years infrastructure sale, a strong outcome for what is typically our weakest quarter.

Overall, we are executing a clear strategy: strengthen our core markets, improve customer value, expand convergence, and maintain disciplined cash flow management."
