Memo

MILLICOM INTERNATIONAL CELLULAR SA (TIGO). Latest full fiscal year: 2025; data up to 2025-12-31.

Figures computed from the financial statements: revenue 5.8 bn USD in 2025; YoY growth 0.3%; net margin 22.6%; ROE 36.2%.

The estimated value range is 110.68–189.52 USD per share (median of 2 methods, agreement: high); assumptions are illustrative. Against the central value of 136.63 USD, the price of 77.09 USD leaves a potential of 77.2% (value / price − 1) and a margin of safety of 43.6% (1 − price / value). The range is the median of the methods' low, central and high values, not a probability interval.

olivLaw score 64/100, methodological classification: neutral profile (score, margin of safety and method agreement together; not a judgement of the right price). Groups assessed only in part: balance, returns. Not investment advice.

Text generated deterministically from the figures shown; no language model. Not investment advice.

What supports the thesis

  • Net margin: 22.6%
  • FCF conversion: 82.4%
  • EPS CAGR 3Y: 83.4%
  • P/E (TTM): 9.8x
  • FCF yield: 8.3%
  • The price is below the estimated value range

What contradicts it

  • Revenue CAGR 3Y: 1.1%
  • Interest coverage: 2.3x
  • Shareholder yield (distributions): 0.9%

Not assessed (insufficient data or a ratio without meaning): Net debt / EBITDA, Current ratio, EV/EBITDA, Payout ratio (FCF).

In brief

Millicom, operating under the Tigo brand, provides fixed and mobile services focused on emerging markets in Latin America across eleven countries. It reported revenue of 5819 million USD for fiscal 2025, and its recent acquisitions in Colombia and Ecuador are reshaping its footprint.

SWOT

Strengths

  • Leading or top-ranked positions in several mobile and broadband markets, combined with an extensive fiber and data infrastructure.
  • Geographic diversification across several Latin American countries, which reduces dependence on a single economy.
  • A mobile financial services platform with a customer base that could support additional services.

Weaknesses

  • Exposure to currency volatility and inflation in economies with macroeconomic instability.
  • Complex ownership structures, including joint ventures, which limit full control over decisions.
  • Dependence on regulations that can change quickly and may impose lower interconnection tariffs.

Opportunities

  • Relatively low penetration of broadband and mobile services, which could offer long-term growth room.
  • Consolidation in Colombia and Ecuador could expand market share and operating efficiencies.
  • B2B, cloud and cybersecurity services could be developed on the existing fiber infrastructure.

Threats

  • Intensified competition after mergers or new market entrants could reduce prices and margins.
  • Legislative or regulatory changes, including limits on disconnecting customers, could affect revenue.
  • Spectrum licenses or authorizations may not be renewed at expiry, or may be reassigned on harsher terms.

Risks

  • Currency and inflation riskhigh

    Devaluation of local currencies and inflation could reduce dollar-reported profitability and make services more expensive for customers.

  • Underdeveloped regulationhigh

    Regulatory frameworks can change rapidly, affecting tariffs, spectrum and interconnection obligations.

  • Integration of acquisitionsmedium

    Integrating recent acquisitions in Ecuador, Uruguay and Colombia could face operational difficulties or delays.

  • Costa Rica merger rejectionmedium

    The regulator's decision not to approve the transaction with Liberty Latin America shows the risk of consolidation being blocked.

  • Spectrum license expirymedium

    Some licenses expire at relatively near dates, and their renewal depends on decisions by local authorities.

Investment thesis

What would need to be true (bull case)

  • If mobile and broadband penetration keeps rising in its markets, revenue could benefit from long-term demand.
  • Consolidation in Colombia and Ecuador could improve competitive position and cost efficiency if the transactions are integrated successfully.
  • The fiber infrastructure and data portfolio could support B2B services with higher margins.

What would break the thesis

  • Currency volatility and inflation in emerging markets could squeeze margins and reduce dollar-reported results.
  • Rising competition or regulation of interconnection tariffs could limit the ability to grow revenue.
  • The complexity of joint venture structures and major transactions could create integration costs and uncertainty.

AI-generatedAI-generated analysis (Claude) from cited public sources; it may contain errors. Not investment advice. As of 27 Oct 2026 · Model: claude-haiku-5-5.

The business

Millicom International Cellular S.A. is a Luxembourg public company offering mobile telephony, fixed broadband, cable and DTH television, mobile financial services through Tigo Money, and B2B solutions across several Latin American countries. According to its 2025 annual report, it ended the year with 49.3 million mobile customers and 4.6 million fixed customer relationships. The company also operates a large infrastructure portfolio, including over 200000 km of fiber 1.

The strategy described by the company rests on the view that mobile and fixed broadband penetration remains low in its markets, which could offer long-term growth room. At the same time, Millicom redefined its segments by country after its 2023-2024 reorganization to focus resources on a leaner corporate structure 1.

During 2025 the company completed several major transactions: the purchase of Otecel in Ecuador and Telefónica Móviles de Uruguay, the sale of tower assets to SBA Communications, and changes to its Colombian structure. The acquisition of control in UNE and Coltel, announced for early 2026, could materially change the scale of its Colombian operations 1.

Segments

Mobile

The mobile segment includes mobile data, voice and SMS, as well as the Tigo Money financial services. It generated 60% of consolidated service revenue in 2025, compared with 58% in 2024 1.

Fixed and other services

This segment covers broadband, pay-TV, fixed telephony and solutions for business and government customers. It accounted for 38% of consolidated service revenue in 2025, down from 40% in 2024 1.

Country segments

Reporting follows the countries of operation: Guatemala, Colombia, Panama, Bolivia, Honduras, Paraguay and an Other group covering El Salvador, Nicaragua, Costa Rica, Uruguay and Ecuador 1.

Market context

Markets served by Millicom show mobile and broadband penetration that management considers low, so revenue depends on middle-class growth, digitalization and demand for residential services. Currency volatility and inflation can affect costs and margins 1.

Competition is described as more intense, and less profitable, when the number of market participants rises. The regulatory framework in these countries is less developed than in the United States or the European Union and can change quickly 1.

Trends

  • Digitalization and data consumptiontailwind

    More connected devices per household and rising data needs support demand for mobile and broadband services.

  • Low penetration in emerging marketstailwind

    Room for higher penetration of fixed and mobile services is seen as significant, especially in countries where penetration is relatively low.

  • Currency volatility and inflationheadwind

    Exchange rate swings and inflationary pressure can raise costs or make services more expensive for customers.

  • Consolidation and regulationmixed

    Market consolidation through deals such as those in Colombia and Ecuador can change competition, while regulators may require lower interconnection fees.

Competitive position

Millicom competes with other large national operators in each country, and its position varies: it leads in mobile in Guatemala, Panama and Paraguay but ranks second in Colombia and Bolivia. The number of market participants directly influences margins, according to the report 1.

The competitive environment is also shaped by market structure, the financial strength of each operator and consolidation situations, which could shift the balance if the announced transactions are completed 1.

  • Local national operators in Latin America

    The source does not name individual competitors; only the large operators in each country are referred to.

  • Coltel

    Colombian operator with which Millicom created a joint mobile infrastructure business, and whose control stake was acquired from Telefónica in 2026.

  • Empresa de Telecomunicaciones de Bogota

    Colombian provider with which the company has wholesale network access agreements in the Bogota metropolitan area.

  • Liberty Latin America

    Operator with which a merger in Costa Rica was agreed, later rejected by the regulator and subject to appeal by the parties.
