UNE’s Foreign-Currency IDR reflects the Negative Outlook on Colombia’s ‘BBB–’ sovereign ratings, as well as the ‘BBB’ Country Ceiling for Colombia.

Key Rating Drivers Supportive Shareholder Agreement: A shareholder agreement between Millicom International Cellular S.A. (BB+/Stable) and Empresas Publicas de Medellin E.S.P. (EPM; BBB–/ Rating Watch Negative) protects the company against the desire by either of its shareholders for higher dividends or a more leveraged capital structure.

The agreement supports TIGO UNE’s capital structure as it requires a super majority for measures such as capex in excess of USD80 million, debt issuances that cause the company ’s debt/EBITDA to be greater than 2.5x, or dividends in excess of 50% of net income.

Strong Market Position: TIGO UNE is the third-largest telecom operator in Colombia by revenue, behind Colombia, a subsidiary of America Movil S.A.B. de C.V. (A–/Stable), and Colombia Telecomunicaciones S.A. E.S.P. (BBB–/Stable).

In the fixed household business, the company is expected to maintain its competitive position, driven by continued growth in revenue-generating users. TIGO UNE’s fixed household and mobile businesses each represent about 36% of total revenue. After an expected downturn in 2020, Fitch forecasts low-single-digit revenue growth and stable Fitch-adjusted EBITDA margins averaging 27% from 2021 onward. Solid Financial Profile: TIGO UNE has maintained a solid financial profile, highlighted by stable leverage and consistent cash flows. Fitch expects leverage, measured as total debt/ Fitch- adjusted EBITDA, to remain flat at approximately 2.1x over the medium term. Leverage has trended down from 2.8x in 2017, mainly due to reduced debt. Fitch’s view is based on an expectation that the company will maintain approximately COP2.7 trillion in debt and generate average EBITDA of approximately COP1.3 trillion in 2020–2022. Fitch expects the company to post neutral to negative FCF over the medium term, as it continues to invest in fixed and mobile networks and coverage in a competitive business environment. Capital intensity is expected to average 27% of Fitch’s projected revenues over the rating horizon, which is higher than the average capex intensity of 18% in 2015–2019.

Ownership Structure: TIGO UNE benefits from being a subsidiary of Millicom and EPM. EPM is the economic parent of TIGO UNE, holding 50% plus one share of the consolidated entity, and has influence on operational and financial decisions. Millicom holds 50% minus one share in its economic stake, but holds a majority of the voting shares and has a controlling stake in the company.

Millicom is a diversified telecom company with operations in 10 countries across Latin America and Africa. Millicom’s ratings reflect its geographic diversification, strong brand recognition and network quality, and leading market positions. EPM is a leading electricity generator in Colombia and has a diversified portfolio of utility businesses that include electric generation, transmission and distribution, water and sewage services, natural gas distribution, and garbage collection and disposal services.

Corporates Telecommunications Colombia

Rating Derivation Relative to Peers TIGO UNE’s business is similar to that of direct competitor Colombia Telecomunicaciones, with similar revenue shares of the Colombian market. TIGO UNE has a longer history of maintaining lower leverage, which supports a one notch higher rating. TIGO UNE is also relatively stronger in the fixed broadband and pay-TV business, which could imply more subscription-like cash flows, as the Colombian mobile market is mostly prepaid, at approximately 80%.

TIGO UNE’s financial performance and leverage profile is expected to be more stable than Chile’s Empresa Nacional de Telecomunicaciones S.A. (ENTEL; BBB–/Negative). ENTEL ’s ratings reflect the intense competitive landscape amid increasing mobile industry maturity in Chile, the company’s aggressive growth strategy in Peru and increased leverage. Similarly, TIGO UNE’s overall credit profile is much stronger than ‘BB’ category domestic telecom peers such as Empresa de Telecomunicaciones de Bogota, S.A., E.S.P. (ETB; BB+/Stable). Fitch estimates ETB will find it difficult to improve EBITDA performance, given its low network penetration and rapidly contracting cash flows.

TIGO UNE’s ‘BBB’ ratings are one notch below Telefonica Moviles Chile S.A. (BBB+/Stable), the leading integrated telecommunications service provider in Chile. In comparison, TIGO UNE holds a secondary position in Colombia behind Claro in the fixed business, and is the third- largest mobile player by market share. TIGO UNE’s ratings incorporate a linkage with Millicom, which holds the controlling majority of shares in the company. Despite the absence of a ring-fencing mechanism to limit TIGO UNE’s cash upstream to its controlling shareholder, Fitch does not expect this relationship to impair TIGO UNE’s ability to execute its capex strategy while maintaining a credit profile in line with the rating. TIGO UNE is one of Millicom’s most important EBITDA contributors, highlighting its financial importance to the parent’s credit profile.

Rating Sensitivities Factors that Could, Individually or Collectively, Lead to Positive Rating Action/Upgrade • Stabilization of the Colombian sovereign rating would lead to a Stable Outlook for TIGO UNE’s Foreign Currency IDR;

• Total debt/EBITDA below 2.0x or net debt/EBITDA below 1.5x on a sustained basis due to a strengthening of the company’s competitive position or FCF being used to pay down debt. Factors that Could, Individually or Collectively, Lead to Negative Rating Action/Downgrade • Deterioration in market position due to greater than expected competition;

• Persistently negative FCF due to higher than expected shareholder distributions or capex;

• Total debt/EBITDA increasing to over 3.0x, or net debt/EBITDA above 2.5x on a sustained basis; • A downgrade to Colombia’s ‘BBB’ Country Ceiling would likely lead to a downgrade of TIGO UNE’s Foreign Currency IDR. Liquidity and Debt Structure Strong Liquidity Profile: TIGO UNE’s stable CFFO and manageable debt amortization profile support its strong liquidity profile. The company had no short-term debt as of June 30, 2020, compared with a readily available cash balance of COP462 billion and expected annual average CFFO of COP1.2 trillion over the ratings horizon. The next relevant debt maturity is COP150 billion, due in 2023 from a local bond issuance. Fitch expects liquidity to remain strong over the ratings horizon.

How to Interpret the Forecast Presented

The forecast presented is based on Fitch Ratings’ internally produced, conservative rating case forecast. It does not represent the forecast of the rated issuer. The forecast set out above is only one component used by Fitch Ratings to assign a rating or determine a rating outlook, and the information in the forecast reflects material but not exhaustive elements of Fitch Ratings’ rating assumptions for the issuer’s financial performance. As such, it cannot be used to establish a rating, and it should not be relied on for that purpose. Fitch Ratings’ forecasts are constructed using a proprietary internal forecasting tool, which employs Fitch Ratings’ own assumptions on operating and financial performance that may not reflect the assumptions that you would make. Fitch Ratings’ own definitions of financial terms such as EBITDA, debt or cash flow may differ from your own such definitions. Fitch Ratings may be granted access, from time to time, to confidential information on certain elements of the issuer’s forward planning. Certain elements of such information may be omitted from this forecast, even where they are included in Fitch Ratings’ own internal deliberations, where Fitch Ratings, at its sole discretion, considers the data may be potentially sensitive in a commercial, legal or regulatory context. The forecast (as with the entirety of this report) is produced strictly subject to the disclaimers set out at the end of this report. Fitch Ratings may update the forecast in future reports but assumes no responsibility to do so. Original financial statement data for historical periods is processed by Fitch Solutions on behalf of Fitch Ratings.

FX Screener TIGO UNE’s U.S. dollar-denominated capex is close to 66% of total capex, while U.S. dollar- denominated operating expenditures are 19% of the total. The company implements a derivative strategy to cover 40%–50% of its U.S. dollar-denominated operating expenditures such as programming costs, handsets, TV content and licenses, and capex, such as 4G and customer-premises equipment. For the remaining capex consideration, the strategy is to negotiate with suppliers ahead of time to lock in an exchange rate deemed appropriate or to build up U.S. dollar reserves with which to finance capex.

A 20% depreciation of the Colombian peso would result in a 7% EBITDA reduction, given that approximately 19% of its cost structure is in U.S. dollars, while its revenues are almost 100% denominated in Colombian pesos. As a result, under this stress scenario, gross leverage would deteriorate by approximately 0.2x.

Reproduction or retransmission in whole or in part is prohibited except by permission. All rights reserved. In issuing and maintaining its ratings and in making other reports (including forecast information), Fitch relies on factual information it receives from issuers and underwriters and from other sources Fitch believes to be credible. Fitch conducts a reasonable investigation of the factual information relied upon by it in accordance with its ratings methodology, and obtains reasonable verification of that information from independent sources, to the extent such sources are available for a given security or in a given jurisdiction. The manner of Fitch’s factual investigation and the scope of the third-party verification it obtains will vary depending on the nature of the rated security and its issuer, the requirements and practices in the jurisdiction in which the rated security is offered and sold and/or the issuer is located, the availability and nature of relevant public information, access to the management of the issuer and its advisers, the availability of pre-existing third-party verifications such as audit reports, agreed-upon procedures letters, appraisals, actuarial reports, engineering reports, legal opinions and other reports provided by third parties, the availability of independent and competent third-party verification sources with respect to the particular security or in the particular jurisdiction of the issuer, and a variety of other factors. Users of Fitch’s ratings and reports should understand that neither an enhanced factual investigation nor any third-party verification can ensure that all of the information Fitch relies on in connection with a rating or a report will be accurate and complete. Ultimately, the issuer and its advisers are responsible for the accuracy of the information they provide to Fitch and to the market in offering documents and other reports. In issuing its ratings and its reports, Fitch must rely on the work of experts, including independent auditors with respect to financial statements and attorneys with respect to legal and tax matters. Further, ratings and forecasts of financial and other information are inherently forward-looking and embody assumptions and predictions about future events that by their nature cannot be verified as facts. As a result, despite any verification of current facts, ratings and forecasts can be affected by future events or conditions that were not anticipated at the time a rating or forecast was issued or affirmed. The information in this report is provided “as is” without any representation or warranty of any kind. A Fitch rating is an opinion as to the creditworthiness of a security. This opinion is based on established criteria and methodologies that Fitch is continuously evaluating and updating. Therefore, ratings are the collective work product of Fitch and no individual, or group of individuals, is solely responsible for a rating. The rating does not address the risk of loss due to risks other than credit risk, unless such risk is specifically mentioned. Fitch is not engaged in the offer or sale of any security. All Fitch reports have shared authorship. Individuals identified in a Fitch report were involved in, but are not solely responsible for, the opinions stated therein. The individuals are named for contact purposes only. A report providing a Fitch rating is neither a prospectus nor a substitute for the information assembled, verified and presented to investors by the issuer and its agents in connection with the sale of the securities. Ratings may be changed or withdrawn at anytime for any reason in the sole discretion of Fitch. Fitch does not provide investment advice of any sort. Ratings are not a recommendation to buy, sell, or hold any security. Ratings do not comment on the adequacy of market price, the suitability of any security for a particular investor, or the tax- exempt nature or taxability of payments made in respect to any security. Fitch receives fees from issuers, insurers, guarantors, other obligors, and underwriters for rating securities. Such fees generally vary from US$1,000 to US$750,000 (or the applicable currency equivalent) per issue. In certain cases, Fitch will rate all or a number of issues issued by a particular issuer, or insured or guaranteed by a particular insurer or guarantor, for a single annual fee. Such fees are expected to vary from US$10,000 to US$1,500,000 (or the applicable currency equivalent). The assignment, publication, or dissemination of a rating by Fitch shall not constitute a consent by Fitch to use its name as an expert in connection with any registration statement filed under the United States securities laws, the Financial Services and Markets Act 2000 of the United Kingdom, or the securities laws of any particular jurisdiction.
