Millicom (Tigo) strengthens its position in Colombia following the successful acquisition of the government stake in Coltel

This milestone enhances scale and investment capacity to strengthen network capabilities and support future growth in Colombia.

Luxembourg, April 27, 2026 – Millicom International Cellular S.A. ("Millicom") today announced it has acquired the remaining 32.5% equity stake in Colombia Telecomunicaciones S.A. E.S.P. ("Coltel") formerly held by La Nación. This milestone follows the successful conclusion of the tender offer for Telefónica’s controlling stake in February 2026 and marks the final step in Millicom’s strategic consolidation of the entity.

The acquisition represents a decisive moment for the Colombian telecommunications sector. By integrating Coltel fully into its operations, Millicom is creating a large-scale, financially viable operator with the enhanced investment capacity required to accelerate the country’s digital transformation.

The consolidation delivers the scale needed to accelerate nationwide 5G deployment, enhance service quality through combined technical capabilities, and support government efforts to expand digital inclusion—ultimately providing faster, more reliable connectivity and a more seamless digital experience for millions of Colombians.

The transaction takes place in an evolving competitive landscape, where traditional operators compete with global digital platforms, satellite providers, and other connectivity players. Scale, investment capacity, and operational efficiency are key to remaining competitive.

"This final step in the acquisition of Coltel reflects our long-term commitment and conviction in Colombia as a core market," said Marcelo Benitez, CEO of Millicom. "By unifying these operations, we are strengthening our ability to compete in a rapidly evolving industry, accelerate next-generation infrastructure, and contribute to Colombia’s long-term digital and economic development."
