What Millicom (Tigo) does

Millicom International Cellular S.A. is a Luxembourg-headquartered telecommunications operator (NASDAQ: TIGO) that delivers mobile, fixed-line, broadband, pay-TV, and digital financial services under the Tigo brand to more than 46 million customers across 14+ Latin American countries, including Colombia, Chile, Ecuador, Uruguay, Honduras, Guatemala, Paraguay, Panama, Costa Rica, El Salvador, and Nicaragua. The company is executing an aggressive M&A-led regional consolidation strategy, having acquired Telefónica's Colombian (Coltel/Movistar), Ecuadorian, and Uruguayan operations, and entered Chile via a 51%/49% joint venture with NJJ Holdings, positioning itself as the second-largest telecom operator in Colombia.

The underlying technology stack includes 5G mobile networks (deployed with ZTE across Chile, Ecuador, Bolivia, Brazil, and Peru with over 37,000 AAU/RRU units), fiber-to-the-home broadband, the Tigo Money mobile financial services platform, and a capacity stake in the TAM-1 submarine cable system (7,000+ km, 18Tbps per fiber pair) linking the U.S., Caribbean, Central, and South America. The product portfolio spans Tigo Mobile, Tigo Home/Fixed, Tigo Business/Enterprise (managed connectivity, cloud, and network services), and Tigo Sports (sports content across six Central American markets, sold to FOX Latin America in April 2026).

Millicom's business model is anchored by recurring subscription revenue from consumer and enterprise telecommunications services (monthly billing for consumers, annual contracts for B2B), supplemented by transaction-based infrastructure monetization such as the $975 million tower sale to SBA Communications covering 2,020 sites in Central America. Reported 2025 revenue reached $5.8 billion with a 43.2% EBITDA margin and record $916 million equity free cash flow; Q1 2026 revenue of $1,985 million (up 45.1% YoY) reflects full consolidation of recent acquisitions. The company carries 2.76x leverage following its acquisition spree, holds a $14.9 billion market capitalization, and is targeting $900 million in equity FCF for 2026.
