Millicom completes acquisition of Colombia Telecomunicaciones By Investing.com

Millicom completed the acquisition of the remaining 32.5% stake in Colombia Telecomunicaciones, fully consolidating its Colombian telecom asset after earlier buying Telefónica’s controlling stake in February 2026. The company says the deal strengthens its ability to deploy nationwide 5G and expand digital services in Colombia. Financial terms were not disclosed, but the move supports Millicom’s long-term Latin American expansion strategy.

Analysis

Millicom’s full control of Colombia is less about headline ownership than about removing friction from capital allocation: once the last minority overhang disappears, management can push network integration, pricing, and capex timing without negotiating leakage to legacy holders. That tends to matter most in the 6-18 month window, because the first value creation comes from eliminating duplicated commercial spend and rationalizing spectrum/network rollout, not from immediate top-line acceleration.

The second-order winner is the vendor ecosystem tied to 5G and fiber densification: radio, backhaul, tower, and field-services spend should be pulled forward if management is serious about using Colombia as a showcase market. The losers are likely smaller regional broadband and mobile challengers that compete on price but lack balance-sheet flexibility; a cleaner, fully integrated TIGO can subsidize customer acquisition and bundle mobile/fixed offers more aggressively, which usually compresses churn and ARPU in the weaker competitors before it shows up in reported market share.

The market is probably underestimating execution risk embedded in a high-return stock: after a large rerating, the next leg depends on synergy delivery and leverage management, not just strategic intent. Any disappointment on capex intensity, FX translation, or regulatory pushback around spectrum and pricing could stall the rerating for several quarters, especially if Latin American credit spreads widen and the company’s refinancing optionality becomes more important than growth.

TEF’s indirect read-through is mildly negative: the strategic value of exiting Columbia is validated, but it also highlights that TEF monetized complexity while leaving the operational upside to Millicom. Consensus may be too complacent about how much optionality a cleaner Colombian asset base creates for TIGO relative to the rest of the regional telco complex; if the integration works, the valuation gap versus slower-growth EM peers could widen further over the next 2-3 reporting cycles.

Key Decisions for Investors

• Long TIGO into the next 1-3 quarters on post-close integration upside; target a continued rerating if management proves it can convert strategic control into EBITDA margin expansion. Stop if capex intensity rises without visible churn improvement.
• Buy TIGO call spreads 3-6 months out to express upside from a multiple expansion while limiting downside after the strong run; best if entered on any pullback tied to broader EM risk-off.
• Short a basket of lower-quality LatAm telecom operators versus long TIGO as a relative-value pair over 6-12 months; the thesis is that scale and full-stack integration will let TIGO take share while weaker names absorb margin pressure.
• Avoid chasing TEF on this headline; use any strength to fade if the market starts pricing a broader asset-sale re-rating, since this looks more like disciplined portfolio cleanup than a growth catalyst.
• Monitor Colombian capex/vendor names for a lagging beneficiary trade over the next 2-4 quarters; the first-order spend often shows up before the market fully prices the network buildout.
