Earnings Release

Q1 2023

Luxembourg, April 27, 2023

Strong mobile performance continued in Q1

Highlights Q1 2023*

Revenue down 2.8% mainly due to currency depreciation compared to the prior year. Excluding currency impacts, revenue increased 2.2% year-on-year.
Service revenue increased 2.2% organically fueled by growth across all business units including 6.0% growth in B2B and 1.9% growth in mobile driven by 8.8% growth in postpaid, as well as growth in most countries.
Operating profit 19.0% lower, mostly reflecting currency depreciation and lower EBITDA, which declined 6.2% organically, impacted by restructuring costs, as well as costs associated with the buyout discussions, the planned tower and Tigo Money carve-outs, and higher non-cash share-based compensation.
Net profit of $3 million compared to $23 million in Q1 2022.
Maintained MSCI ESG rating at "AA", placing us above the industry average and classifying our corporate governance as a leader among global telecom sector peers.

Millicom Chief Executive Officer Mauricio Ramos commented:

"During the quarter, we continued to execute our plans, which are yielding positive results as we navigate the challenging macroeconomic environment. I am particularly pleased with our performance of Tigo Business (our B2B operation), where organic growth continued to accelerate, thanks to our clearly-defined strategy centered on digital services. We also saw robust growth in Mobile, as a result of recent network investments and pricing actions, which are driving an ongoing and valuable shift to postpaid and improving ARPU trends. Additionally, our continued commitment to ESG yielded positive results as we maintained our MSCI ESG rating at 'AA', placing above the industry average and reinforcing our position as a leader in corporate governance.

Earnings Release

Q1 2023

As we look to the future, we remain focused on improving operational efficiency. During Q1, we incurred meaningful restructuring costs as we began to implement Project Everest, a comprehensive program that is expected to deliver run-rate savings of over $100 million by the end of 2024. This project will allow us to become more agile and efficient, and we expect the financial benefits will begin accruing during the year.

We have also made significant strides in optimizing our investment activity, securing multi-year agreements with key vendors to lower our annual spend as we commit to expand capacity and coverage of our networks in coming years. As a result of these initiatives and our solid top-line performance, we remain confident in our ability to achieve the medium-term targets we outlined in early 2022."

In Q1 2023, revenue declined 2.8% year-on-year, as currency depreciation (mostly the Colombian peso down 17.2% year-on-year and the Paraguayan guarani down 4.2% year-on-year), offset positive organic growth in most countries and across business units, driven by B2B and postpaid. Excluding the effect of foreign exchange, revenue and service revenue both increased 2.2% on an organic basis.

Cost of sales increased 0.4% year-on-year, as the depreciation of currencies offset increases in content costs related to the launch of Vix, as well as higher bad debt expense stemming mostly from growth in subscription businesses in the quarter. Operating expenses increased 3.4% year-on-year mostly due to $15 million in organizational restructuring costs related to Project Everest, and costs associated with the buyout discussions and the planned Tigo Money and tower (LATI) carve-outs, as well as the non-cash impact of a higher stock price on share-based compensation.

Earnings Release

Q1 2023

Depreciation decreased 5.0% year-on-year to $244 million due to the depreciation of the Colombian peso, while amortization increased 7.4% to $87 million due to higher software, spectrum and broadcasting rights costs, partly offset by the positive effect of the weaker Colombian peso. As a result of the above factors, operating profit declined 19.0% year-on-year.

Net financial expenses rose $25 million year-on-year, mostly due to inflation-linked interest, partially offset by the positive effect of the weaker Colombian peso on our peso-denominated debt. Other non-operating income of $19 million mainly related to foreign exchange gains in Paraguay, Costa Rica and Colombia, as these currencies appreciated during the quarter. This compares to $4 million in Q1 2022.

Tax expense of $59 million in Q1 2023 reflects withholding tax on higher cash upstream and the impairment of certain income tax credits in Colombia. This compares to $69 million in Q1 2022, which included a $25 million provision resulting from a one-off adverse tax ruling. Non-controlling interests gain of $23 million in Q1 2023, compares to a loss of $1 million in Q1 2022 reflecting our partners' share of net losses in Colombia in Q1 2023 compared to net profit in Q1 2022.

Net profit attributable to owners of the company was $3 million, or $0.02 per share, compared to a net profit of $23 million ($0.18 per share) in Q1 2022. The weighted average number of shares outstanding during the quarter was 170.91 million. As of March 31, 2023, there were 172.10 million shares issued and outstanding, including 1.18 million held in treasury.

Cash Flow

Operating Free Cash Flow (OFCF) of $17 million in Q1 2023 compares to $101 million in Q1 2022. The decline of $84 million reflects the impact of currency depreciation during the last year, expenses related to the organizational restructuring, investments in our Tigo Money and tower businesses, and buyout discussions, as well as increased capex and spectrum spend, partially offset by lower tax payments. The increase in spectrum reflects the acquisition of additional AWS spectrum in Panama for $20 million. Working capital improved $8 million versus the same quarter last year, as general management more than offset a $20 million final payment of a tax amnesty from Q4 2022.

Taxes paid decreased to $37 million in Q1 2023 from $62 million in Q1 2022, mainly due to lower profitability. Finance charges increased $26 million year-on-year to $129 million mainly reflecting the semi-annual coupon paid in Q1 2023 on the Guatemala bond issued in January 2022.

Lease interest and lease principal payments totaled $69 million in Q1 2023, down $13 million from $82 million in Q1 2022, due to the 2022 disposal of our Africa operation which had large lease liabilities, as well as the effect of a weaker Colombian peso on leases denominated in local currency in that country. Finally, repatriation from joint ventures and associates was $48 million in Q1 2023, an increase of $34 million compared to Q1 2022, due to the anticipation of repatriation from Honduras, which continues to contribute meaningfully to Group cash flow.

Debt

Beginning in Q1 2023, we have amended our definition of Net Debt to include the carrying value of derivative financial instruments. We have also changed our definition of EBITDA after leases ("EBITDAaL") to reflect the depreciation on rights-of-use assets and interest expense on lease liabilities from the Income Statement, rather than the cash payments from the Cash Flow Statement. See page 12 for a description of non-IFRS measures and for reconciliations to the nearest equivalent IFRS measures and page 13 for a reconciliation of EBITDA after leases.

* Net Debt, Net financial obligations, EBITDA and Leverage are non-IFRS measures and are IFRS consolidated figures. See page 12 for a description of non-IFRS measures and for reconciliations to the nearest equivalent IFRS measures. Cash includes term deposits of $1 million as of March 31, 2023. Proforma adjustments relate to the acquisition of the Guatemala operation on November 12, 2021.

Gross debt increased $41 million during the quarter to $6,845 million as of March 31, 2023, compared to $6,804 million at the end Q4 2022, and the percent of gross debt in local currency1 remained unchanged at 40%. Meanwhile, 82% of our debt was at fixed rates2 with an average maturity of 5.3 years. Approximately 62% of gross debt at March 31, 2023 was held at our operating entities, while the remaining 38% was at the corporate level. All these debt metrics were in line with our targets.

The average interest rate on our debt increased to 6.5% from 6.3% at the end of Q4 2022, reflecting the impact of higher interest rates on our floating rate debt. On our dollar-denominated debt3, the average rate was stable at 5.5% with an average maturity of 5.9 years as of March 31, 2023, down from 6.4 years as of December 31, 2022.

Our cash position was $904 million as of March 31, 2023, a decline of $135 million compared to $1,039 million as of December 31, 2022, and 82% was held in U.S. dollars. As a result, our net debt was $5,983 million as of March 31, 2023, an increase of $184 million during the quarter, reflecting mostly the seasonal EFCF outflow in Q1 as well as the effect of currency appreciation during the quarter on our local currency debt.

Including lease liabilities of $1,026 million, net financial obligations were $7,009 million as of March 31, 2023, an increase of $195 million during the quarter, reflecting the increase in net debt and the effect of currency appreciation on our local currency denominated leases during the quarter. Leverage, which includes lease obligations, was 3.23x as of March

Operating performance

The information contained herein can also be accessed electronically in the Financial & Operating Data Excel file published at www.millicom.com/investors alongside this earnings release.

Business units

We discuss our performance under two principal business units:

1. Mobile, including mobile data, mobile voice, and mobile financial services (MFS) to consumer, business and government customers;

2. Fixed network services, including broadband, Pay TV, content, and fixed voice services for residential (Home) customers, as well as voice, data and value-added services and solutions to business and government customers.

On occasion, we also discuss our performance by customer type, with B2B referring to our business and government customers, while B2C includes residential and personal consumer groups.

Market environment

Economic activity remained subdued in most countries, although inflation continued to recede, with the notable exception of Colombia, where inflation continued to increase during the quarter. Foreign exchange rate volatility remained elevated in some of our markets, with nearly all floating currencies appreciating during the quarter, led by the Costa Rican colon, the Colombian peso and Paraguayan guarani which ended the quarter up 10.3%, 4.0% and 2.1%, respectively. Despite the strengthening trend observed during Q1, most floating currencies remained well below average levels of Q1 2022, with the Colombia peso and the Paraguayan guarani down 17.2% and 4.2%, respectively, year-on-year. Foreign exchange rates and movements are presented on page 15.

* KPIs re-presented to include Guatemala in all periods and exclude both Africa, which has been classified as discontinued operations, and our joint venture in Honduras, which is not consolidated in the Group figures.

Mobile services

In Q1 2023 our customer base remained broadly stable, decreasing by 11,000 during the quarter to end at 40.6 million, an increase of 1.5% year-on-year. Postpaid continued to perform very strongly with net additions of 168,000 in Q1, including more than 120,000 in Colombia, where we have added over 350,000 postpaid customers in the last twelve months.

Mobile ARPU declined 3.9% mostly due to the effect of the weaker Colombian peso. Excluding the impact of foreign exchange, local currency ARPU increased slightly, driven by low-single digit growth in El Salvador and Nicaragua and mid-single digit in Colombia and Bolivia. The improvement in organic ARPU trends reflects price increases implemented in recent quarters, as well as the shift in mix toward postpaid.

Broadband and other fixed services

At the end of Q1 2023, our networks passed 13.0 million homes, an increase of 96,000 during the quarter, reflecting our decision to moderate investment consistent with slower macroeconomic growth and lower ARPU in some markets. During the quarter, HFC/FTTH customer relationships declined 15,000 net, as we continue to prioritize price discipline amidst a challenging macroeconomic environment and elevated competition in some markets. Penetration on our HFC/FTTH network was 32.4%, down from 34.0% in Q1 2022, given the expansion of our network during the first quarter of 2023.

Home ARPU declined 5.8% year-on-year, due largely to the weaker Colombian peso. Organically, Home ARPU declined 1.0%, reflecting increased competition and a shift in mix toward Broadband-only customers, which generate lower ARPU, as well as lower cost and capex. In local currency, ARPU increased in four countries, reflecting recent price increases across our footprint.

Earnings Release

Q1 2023

Financial indicators

In Q1 2023, revenue declined 2.8% year-on-year to $1,369 million, while service revenue declined 2.7% to $1,264 million. Excluding currency movements, organic service revenue growth was 2.2% year-on-year, reflecting growth in all business units, including 6.0% organic growth in B2B and 8.8% organic growth in postpaid, and growth in most countries, as described below:

Guatemala service revenue was broadly flat, declining 0.2% in local currency, as growth in subscription businesses was offset by lower revenue from incoming international traffic and in prepaid mobile, which showed signs of recovery from H2 2022 levels but remained below Q1 2022.
Colombia service revenue grew 3.6% in local currency mainly due to high single-digit growth in mobile driven by postpaid and mid-single digit growth in B2B, partially offset by a decline in Home.
In Paraguay, 6.0% local currency service revenue growth reflected growth across all business units, including double digit growth in B2B.
Panama grew 4.3%, as low-teen growth in Mobile driven by strong postpaid and prepaid and mid-single digit growth in B2B more than outweighed a small decline in Home.
Bolivia declined 1.5%, as growth in Home and B2B could not offset Mobile, which declined as a result of a change in regulation that took place in August and impacted mobile data overage rates.
El Salvador increased 3.1%, with all three business units contributing, while service revenue grew 6.6% in Nicaragua and declined 1.4% in Costa Rica, as the 14.8% appreciation of the colon impacted revenue of B2B, given a significant majority of customer contracts are in dollars. In U.S. dollar terms, Costa Rica revenue grew 13.4%.
Service revenue in our Honduras joint venture (not consolidated) grew 5.8% in local currency, as all three business units grew mid-to-high single-digits during the quarter.

Earnings Release

Q1 2023

* Service revenue, EBITDA, EBITDA margin, Capex, OCF and organic growth are non-IFRS measures. Capex is defined as capital expenditures excluding spectrum, license costs and lease capitalizations. See page 12 for a description of non-IFRS measures and for reconciliations to the nearest equivalent IFRS measures.

By business unit, Home service revenue increased 0.6% organically, impacted by lower ARPU in markets such as Colombia and Bolivia, and a decline in customer relationships during the quarter. In our Mobile B2C business, organic service revenue grew 1.9% year-on-year, driven by postpaid, which grew 8.8% due to continued customer conversion from prepaid to postpaid as well as price increases implemented over the last year. Finally, organic B2B service revenue accelerated to 6.0%, fueled by a 28.1% increase in digital services and growth across most countries.

EBITDA was $507 million, a decrease of 10.0% year-on-year. Excluding the impact of foreign exchange, EBITDA declined 6.2% organically year-on-year. Several factors contributed to the decline, including:

organizational restructuring costs for $15 million related to Project Everest;
the impact of a higher stock price on non-cash share-based compensation;
costs associated with the buyout discussions;
investments related to our Tigo Money and tower (LATI) businesses; and,
costs associated with the recent addition of Vix to our content supermarket in our Central American markets.

Excluding all of these items, EBITDA would have declined approximately 1% organically. By country, EBITDA was as follows:

Guatemala declined 6.4%, reflecting increased commercial intensity to strengthen our prepaid offering as well as increased content costs.
Colombia declined 3.8%, impacted by severance payments for $7 million related to Project Everest. Adjusting for this one-time item, EBITDA would have grown 4.2%.
Panama declined 0.1%, impacted by severance payments for $1 million related to Project Everest. Adjusting for this one-time payment, EBITDA would have grown 1.4%.
Paraguay declined 0.4% mainly due to increased content costs as well as severance payments for $1 million related to Project Everest. Adjusting for this one-time payment, EBITDA would have increased 0.8%.
Bolivia declined 5.4%, impacted by the regulatory change implemented in August.
El Salvador grew 1.6%, Nicaragua grew 8.9%, and Costa Rica was flat, declining 0.3%.
Our joint venture in Honduras (not consolidated) increased 4.4%, reflecting improved revenue trends.

Capex was $185 million in the quarter. In Mobile, we added more than 300 Points of Presence to our 4G network, ending with more than 18,200, an increase of 11% year-on-year. At the end of Q1 2023, our 4G networks covered approximately

Q1 2023

80% of the population4, up from approximately 78% as of Q1 2022. During the quarter, we agreed to renew, for 20 years, one of our licenses related to spectrum in the 1900 MHz band in Colombia. Although payment and other terms are not yet defined, we recognized an intangible spectrum asset with a corresponding liability of $259 million.

Operating Cash Flow (OCF) declined year-on-year to $322 million in Q1 2023 from $365 million in Q1 2022, which included $8 million of Capex related to Africa. Excluding the impact of currencies and the Capex related to Africa, OCF decreased 7.9% organically.

ESG highlights - Q1 2023

On April 6, 2023, we received the ESG ratings from MSCI, where Millicom's rating remains unchanged at "AA", placing us above the industry average and classifying our corporate governance as a leader among global telecom sector peers. The MSCI ESG Ratings measure a company's resilience to long-term ESG risks. Companies are scored on an industry-relative AAA-CCC scale across the most relevant Key Issues based on a company's business model.

Likewise, in 2022 Millicom received a "B" rating on the Carbon Disclosure Project (CDP), showing our commitment to reduce carbon emissions and climate change and during March 2023, we were recognized as a 2022 CDP Supplier Engagement Leaderboard. This recognition means that Tigo is among the top 8% of suppliers evaluated for their engagement on climate change, according to CDP's 2022 disclosure. In Q1, we started the very detailed evaluation process for 2022.

In Q1, the Board of Directors proposed amending the long-term incentive plan to include an ESG component of 10%. The proposal is subject to shareholder approval at the AGM.

Environment

During Q1, we published our Annual Report 2022 with all environmental indicators that show progress toward our commitment to Science-Based Targets (SBT) and continuous improvement. In February 2023, GSMA Intelligence published the technical document "Going Green: Benchmarking the Energy Efficiency of Mobile Networks." As a result of our commitment, we were the first network operator in the Americas to join the initiative.

Society

Digital Education

Likewise, our Annual Report highlighted that we trained more than 102,000 teachers with our Maestr@s Conectad@s program during 2022. This included live events in Bolivia, Paraguay, El Salvador and Colombia. As of December 31, 2022,

more than 171,000 women were trained in our Conectadas program. During the first quarter of 2023, we worked on strengthening our digital platforms, improving their functionality for both Conectadas and Maestr@s Conectd@s.

Governance

In conjunction with our Annual Report, we published our 2023 Corporate Governance Report. The report details Millicom's Framework and Shareholder Governance and Board Governance, among other topics.

Compliance

During Q1 2023, we formally launched the 2023 Compliance Indicators applicable to our Local Operations. As in prior years, the 2023 KPIs represent a set of operational Compliance expectations for the business, and are linked to local executive compensation.

In addition, we started preparing materials for our flagship Annual Code of Conduct Training. Like its prior iteration, this edition is also designed and produced using 100% in-house talent, with key participation from management and all levels of the organization.

Lastly, we recently upgraded our Third Party Due Diligence system, giving us improved ability to monitor our third party risk management and connect to other platforms.

Non-IFRS Measures

This press release contains financial measures not prepared in accordance with IFRS. These measures are referred to as "non-IFRS" measures and include: non-IFRS service revenue, non-IFRS EBITDA, and non-IFRS Capex, among others defined below. Annual growth rates for these non-IFRS measures are often expressed in organic constant currency terms to exclude the effect of changes in foreign exchange rates, the adoption of new accounting standards, and are proforma for material changes in perimeter due to acquisitions and divestitures. The non-IFRS financial measures are presented in this press release as Millicom's management believes they provide investors with an additional information for the analysis of Millicom's results of operations, particularly in evaluating performance from one period to another. Millicom's management uses non-IFRS financial measures to make operating decisions, as they facilitate additional internal comparisons of Millicom's performance to historical results and to competitors' results, and provides them to investors as a supplement to Millicom's reported results to provide additional insight into Millicom's operating performance. Millicom's Remuneration Committee uses certain non-IFRS measures when assessing the performance and compensation of employees, including Millicom's executive directors.

The non-IFRS financial measures used by Millicom may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies - refer to the section "Non-IFRS Financial Measure Descriptions" for additional information. In addition, these non-IFRS measures should not be considered in isolation as a substitute for, or as superior to, financial measures calculated in accordance with IFRS, and Millicom's financial results calculated in accordance with IFRS and reconciliations to those financial statements should be carefully evaluated.

The following changes were made to some definitions of the Group's non-IFRS financial measures as disclosed in the 2022 Annual Report: the definition of 'EBITDA after leases' has changed from lease cash payments to income statement line items (interest expense and depreciation charge). This does not change the manner in which we calculate Equity Free Cash Flow, but aligns our calculation for leverage purposes with peers. The definition of Net Debt has changed to include derivative financial instruments in order to have a more comprehensive view of our financial obligations. Finally, Home ARPU has changed to include equipment rental in our Home revenue, as these are long-term payment plans.

Non-IFRS Financial Measure Descriptions

Service revenue is revenue related to the provision of ongoing services such as monthly subscription fees for mobile and broadband, airtime and data usage fees, interconnection fees, roaming fees, mobile finance service commissions and fees from other telecommunications services such as data services, short message services, installation fees and other value-added services excluding telephone and equipment sales.

EBITDA is operating profit excluding impairment losses, depreciation and amortization, and gains/losses on fixed asset disposals.

EBITDA after Leases (EBITDAaL) represents EBITDA after lease expense and depreciation charge.

EBITDA Margin represents EBITDA in relation to Revenue.

Organic growth represents year-on-year growth excluding the impact of changes in FX rates, perimeter, and accounting. Changes in perimeter are the result of acquisitions and divestitures. Results from divested assets are immediately removed from both periods, whereas the results from acquired assets are included in both periods at the beginning (January 1) of the first full calendar year of ownership.

Net debt is Debt and financial liabilities, including derivative instruments (assets and liabilities), less cash and pledged and time deposits.

17

Earnings Release

Q1 2023

Net financial obligations is Net debt plus lease liabilities.

Leverage is the ratio of net financial obligations over LTM (Last twelve month) EBITDA, proforma for acquisitions made during the last twelve months.

Leverage after leases is the ratio of net debt over LTM (Last twelve month) EBITDA after leases, proforma for acquisitions and disposals made during the last twelve months.

Capex is balance sheet capital expenditure excluding spectrum and license costs and lease capitalizations.

Cash Capex represents the cash spent in relation to capital expenditure, excluding spectrum and licenses costs.

Operating Cash Flow (OCF) is EBITDA less Capex.

Operating Free Cash Flow (OFCF) is EBITDA, less cash capex, less spectrum paid, working capital and other non-cash items, and taxes paid.

Equity Free Cash Flow (EFCF) is OFCF less finance charges paid (net), lease interest payments, lease principal repayments, and advances for dividends to non-controlling interests, plus cash repatriation from joint ventures and associates.

Operating Profit After Tax displays the profit generated from the operations of the company after statutory taxes.

Return on Invested Capital (ROIC) is used to assess the Group's efficiency at allocating the capital under its control to and is defined as Operating Profit After Tax divided by the average invested Capital during the period.

Average Invested Capital is the capital invested in the company operation throughout the year and is calculated with the average of opening and closing balances of the total assets minus current liabilities (excluding debt, joint ventures, accrued interests, deferred and current tax, cash as well as investments and non-controlling interests), less assets and liabilities held for sale.

Average Revenue per User per Month (ARPU) for our Mobile customers is (x) the total mobile and mobile financial services revenue (excluding revenue earned from tower rentals, call center, data and mobile virtual network operator, visitor roaming, national third parties roaming and mobile telephone equipment sales revenue) for the period, divided by (y) the average number of mobile subscribers for the period, divided by (z) the number of months in the period. We define ARPU for our Home customers as (x) the total Home revenue (excluding equipment sales and TV advertising) for the period, divided by (y) the average number of customer relationships for the period, divided by (z) the number of months in the period. ARPU is not subject to a standard industry definition and our definition of ARPU may be different from other industry participants.

Please refer to our 2022 Annual Report for a list and description of non-IFRS measures.
