Millicom International Cellular is rated a cautious buy, driven by robust margins, strong equity free cash flow, and disciplined execution on acquisitions. TIGO's EBITDA margin of 43.2% and record $225M quarterly equity free cash flow highlight operational strength, with 2026 free cash flow targeted at $900M. Acquisition integration, especially in Colombia and Chile, is the main catalyst, with early successes in margin improvement and rapid cash contribution from acquired assets.
