América Móvil 2
Operating and Financial Review as of March 31, 2025 and for the Three-Month Periods Ended March 31, 2024 and 2025 4

This report includes certain financial information as of and for the three-month periods ended March 31, 2024 and 2025.

The information in this report supplements information contained in our annual report on Form 20-F for the year ended December 31, 2024 (File No. 001-16269), filed with the U.S. Securities and Exchange Commission (the “SEC”) on May 14, 2025 (our “2024 Form 20-F”).


FORWARD-LOOKING STATEMENTS

Some of the information contained or incorporated by reference in this report may constitute “forward-looking statements” within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Although we have based these forward-looking statements on our expectations and projections about future events, it is possible that actual events may differ materially from our expectations. In many cases we include, together with the forward-looking statements themselves, a discussion of factors that may cause actual events to differ from our forward-looking statements. Examples of forward-looking statements include the following:

projections of commercial, operating or financial performance, our financing, our capital structure or our other financial items;
statements of our plans, objectives or goals, including those relating to acquisitions, competition and rates;
statements concerning regulation or regulatory developments;
the impact of public health crises;
statements about our future economic performance or that of Mexico or other countries in which we operate;
statements about competitive developments in the telecommunications industry;
other descriptions of factors and trends affecting the telecommunications industry generally and our financial condition in particular; and
statements of assumptions underlying the foregoing statements.

We use words such as “believe,” “anticipate,” “plan,” “expect,” “intend,” “target,” “estimate,” “project,” “predict,” “forecast,” “guideline,” “should” and other similar expressions to identify forward-looking statements, but they are not the only way we identify such statements.

Forward-looking statements involve inherent risks and uncertainties. We caution you that a number of important factors could cause actual results to differ materially from the plans, objectives, expectations, estimates and intentions expressed in such forward-looking statements. These factors, some of which are discussed under “Risk Factors” in our 2024 Form 20-F, include economic and political conditions and government policies in Mexico, Brazil, Argentina, Colombia, Europe and elsewhere, inflation rates, exchange rates, regulatory developments, technological improvements, the impact of public health crises, customer demand and competition. We caution you that the foregoing list of factors is not exclusive and that other risks and uncertainties may cause actual results to differ materially from those in forward-looking statements. You should evaluate any statements made by us in light of these important factors.

Forward-looking statements speak only as of the date they are made. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information or future events or for any other reason.


AMÉRICA MÓVIL

América Móvil, S.A.B. de C.V. (“América Móvil,” “we,” “us,” “our” or the “Company”) is a sociedad anónima bursátil de capital variable organized under the laws of Mexico. We provide telecommunications services in 23 countries. We are a leading telecommunications service provider in Latin America, ranking first in wireless, fixed-line, broadband and Pay TV services based on the number of revenue generating units (“RGUs”). Our largest operations are in Mexico and Brazil, which together account for over half of our total RGUs and where we have the largest market share based on RGUs. We have operations in 16 countries in the Americas and seven countries in Central and Eastern Europe. As of March 31, 2025, we had 323.9 million wireless voice and data subscriptions and 78.2 million fixed RGUs.

Our customers generate revenue for us by purchasing one or more of our services. We refer to each service that a customer purchases as a revenue generating unit (“RGU”). Our management has identified RGUs as a key performance indicator (“KPI”) that helps measure the performance of our operations because it allows the Company to assess its performance on a per-service basis. Each wireless subscription, which includes prepaid and postpaid subscriptions, is counted as a single RGU, while a single fixed-service customer can have multiple RGUs, depending on the services we provide in its respective country. Fixed RGUs consist of fixed voice, fixed data and Pay TV units (which include customers of our Pay TV services and, separately, of certain other digital services). The figures below reflect total wireless subscriptions and fixed RGUs of all our consolidated subsidiaries in the following reportable segments:

Mexico Wireless;
Mexico Fixed;
Brazil;
Colombia;
Southern Cone (Argentina);
Southern Cone (Chile, Paraguay and Uruguay);
Andean Region (Ecuador and Peru);

The following is a summary and discussion of our preliminary unaudited condensed consolidated financial information as of and for the three-month periods ended March 31, 2024 and 2025. The following tables and discussion should be read in conjunction with our audited consolidated financial statements included in our 2024 Form 20-F.

In the opinion of our management, the unaudited condensed consolidated financial information discussed below includes all adjustments, consisting only of normal and recurring adjustments, necessary for the fair presentation of this financial information in a manner consistent with the presentation under IFRS Accounting Standards as issued by the International Accounting Standards Board (“IASB”) (“IFRS”) made in our audited annual consolidated financial statements included in our 2024 Form 20-F.

Condensed Consolidated Results of Operations as of and for the Three-Month Periods Ended March 31, 2024 and 2025

Our unaudited condensed consolidated financial statements are presented in Mexican pesos, but our operations outside of Mexico account for a significant portion of our revenues and expenses. Currency variations between the Mexican peso and the currencies of our non-Mexican subsidiaries, especially the euro, U.S. dollar, Brazilian real, Colombian peso and Argentine peso, affect our results of operations as reported in Mexican pesos.

In the following discussion regarding our results of operations, we include a discussion of the change in the different components of our revenues and expenses between periods at constant exchange rates, i.e., using the same exchange rate from the comparable period of the prior fiscal year to translate the local-currency results of our non-Mexican operations for both periods. We believe that this additional information helps investors better understand the performance of our non-Mexican operations and their contribution to our consolidated results.

All comparisons at constant exchange rates in our consolidated figures exclude Argentina. Our Argentine subsidiary is subject to the accounting guidelines applicable to hyperinflationary economies, with all the accounting variables expressed in real terms at constant Argentine pesos. Pursuant to IFRS Accounting Standards, for consolidation purposes in our consolidated financial statements—with no other economy in the countries in which we operate considered hyperinflationary—Argentine peso figures expressed in constant Argentine peso terms at the prevailing prices at the end of a reporting period must be converted into Mexican pesos at the exchange rate observed at the end of such reporting period. Due to hyperinflationary conditions in Argentina and the magnitude of the Argentine peso’s depreciation, the application of the above-referenced norm generates unusual effects. Therefore, we exclude Argentina from all consolidated figures cited at constant exchange rates.

On October 6, 2022, we combined our Chilean operations with LLA in order to create Claro Chile, SpA, a 50:50 joint venture, as a result of which Claro Chile ceased to be our wholly owned subsidiary, as previously disclosed in our press release furnished on a report on Form 6-K on October 6, 2022. In accordance with IFRS 11, this transaction was classified as a joint venture, since we exercise joint control over Claro Chile, SpA with LLA, and all relevant decisions require the consent of both parties. As a result of the incorporation of the Claro Chile, SpA as a joint venture, in accordance with IFRS 5, the operations of Claro Chile are classified as discontinued operations for the reporting periods prior to 2023 presented in the consolidated financial information included in the annual report 2024 and are recognized through the equity method from October 6, 2022. Accordingly, where applicable, results were presented for the relevant periods in the profit (loss) after tax from discontinued operations in the consolidated financial information included in the annual report 2024. Operating and financial information presented herein therefore excludes Claro Chile, including for periods prior to the joint venture agreement. On October 3, 2024, we received the approval by the National Economic Prosecutor’s Office of the Republic of Chile (Fiscalia Nacional Económica) to consolidate Claro Chile, SpA (which, until then, was still a 50:50 joint venture) into its operations. As a result, on October 31, 2024, we converted our outstanding notes in Claro Chile, SpA into equity and consolidated Claro Chile, SpA into its consolidated financial statements. At the effective date of the conversion, LLA retained an approximate 9.0% interest and AMX an approximate 91.0% interest. As of December 31, 2024, we held a 94.9% interest in Claro Chile, SpA.

Operating Revenues

Total operating revenues for the first three months of 2025 increased by 14.1%, or Ps. 28.7 billion, over the first three months of 2024. At constant exchange rates, total operating revenues for the first three months of 2025 increased by 4.7% over the first three months of 2024, or 2.3% excluding the effects of consolidating Claro Chile, SpA.

Service Revenues – Service revenues for the first three months of 2025 increased by 15.5%, or Ps. 26.9 billion, over the first three months of 2024. At constant exchange rates, service revenues for the first three months of 2025 increased by 5.9% over the first three months of 2024, or 3.4% excluding the effects of consolidating Claro Chile, SpA. This increase at constant exchange rates principally reflects an increase in revenues from our prepaid and postpaid mobile services, broadband and corporate services in the fixed-line networks, which were partially offset by a decrease in revenues from our fixed voice and Pay TV services.


Sales of Equipment – Sales of equipment revenues for the first three months of 2025 increased by 6.0%, or Ps. 1.8 billion, over the first three months of 2024. At constant exchange rates, sales of equipment revenues for the first three months of 2025 decreased by 2.3% over the first three months of 2024, or 4.1% excluding the effects of consolidating Claro Chile, SpA. This decrease at constant exchange rates principally reflects lower sales of smartphones, data-enabled devices and accessories in Austria, Mexico and Peru which were partially offset by higher sales in Brazil and Central America.

Operating Costs and Expenses

Total operating costs and expenses for the first three months of 2025 increased by 14.9%, or Ps. 18.3 billion, over the first three months of 2024. At constant exchange rates, total operating costs and expenses for the first three months of 2025 increased by 5.3% over the first three months of 2024, or 2.1% excluding the effects of consolidating Claro Chile, SpA. This increase in operating costs and expenses at constant exchange rates principally reflects increased costs associated with lease space, logistics, network maintenance and IT services.

Cost of Sales and Services – Cost of sales and services for the first three months of 2025 increased by 12.4%, or Ps. 9.7 billion, over the first three months of 2024. At constant exchange rates, cost of sales and services for the first three months of 2025 increased by 4.1% over the first three months of 2024, or 1.1% excluding the effects of consolidating Claro Chile, SpA. This increase in costs of sales and services at constant exchange rates principally reflects an increase in sales of higher-end smartphones as well as corporate network, IT services and network maintenance. This increase was partially offset by our cost savings program.

Commercial, Administrative and General Expenses – Commercial, administrative and general expenses for the first three months of 2025 increased by 19.1%, or Ps. 8.3 billion, over the first three months of 2024. As a percentage of operating revenues, commercial, administrative and general expenses were 22.4% for the first three months of 2025, compared to 21.4% for the first three months of 2024. At constant exchange rates, commercial, administrative and general expenses for the first three months of 2025 increased by 8.1% over the first three months of 2024, or 4.3% excluding the effects of consolidating Claro Chile, SpA. This increase in commercial, administrative and general expenses at constant exchange rates principally reflects increased expenses for customer service centers and IT solutions.

Other Expenses – Other expenses for the first three months of 2025 increased by 19.7% or Ps. 0.3 billion over the first three months of 2024, principally due to year-over-year appreciation of most of our operating currencies against the Mexican peso.

Depreciation and Amortization – Depreciation and amortization for the first three months of 2025 increased by 16.1%, or Ps. 6.4 billion, over the first three months of 2024. As a percentage of operating revenues, depreciation and amortization were 19.9% for the first three months of 2025, compared to 19.6% for the first three months of 2024. At constant exchange rates, depreciation and amortization for the first three months of 2025 increased by 10.0% over the first three months of 2024, or 2.6% excluding the effects of consolidating Claro Chile, SpA. This increase in depreciation and amortization at constant exchange rates principally reflects the annual increase in site lease payments in accordance with the contracts entered by our subsidiary Telcel, and new sites were also added with Telesites, S.A.B. de C.V. Additionally, in the first quarter of 2025, our subsidiaries in Colombia and Austria made investments in network equipment.

Operating Income

Operating income for the first three months of 2025 increased by 10.0%, or Ps. 4.1 billion, over the first three months of 2024. Operating margin (operating income as a percentage of operating revenues) was 19.3% for the first three months of 2025, compared to 20.0% for the first three months of 2024.

Non-Operating Items

Net Interest Expense – Net interest expense (interest expense less interest income) for the first three months of 2025 increased by 12.7%, or Ps. 1.4

billion, over the first three months of 2024. This increase principally reflects an increase in interest expense from debt due to changes in interest rates in Brazil and the incurrence of new loans by our subsidiary in Colombia following the first
quarter of 2024.

Foreign Currency Exchange Loss, Net – We recorded a net foreign currency exchange loss of Ps. 1.2 billion for the first three months of 2025, compared to our net foreign currency exchange loss of Ps. 1.7 billion for the first three months of 2024. The change in the first three months principally reflects the appreciation of some of the currencies in which our indebtedness is denominated against the Mexican peso, particularly the U.S. dollar, the euro and the British pound sterling.


Valuation of Derivatives, Interest Cost from Labor Obligations and Other Financial Items, Net – We recorded a net gain of Ps. 0.5 billion for the first three months of 2025 on the valuation of derivatives, interest cost from labor obligations and other financial items, net, compared to a net loss of Ps. 0.8 billion for the first three months of 2024. The change in the first three months of 2025 principally reflects a gain on hedging instruments as a result of the appreciation of some of the currencies in which our indebtedness is denominated, allocated to America Movil, S.A.B. de C.V. and by a decrease in the net monetary position gain from our subsidiaries in Argentina.

Income Tax – Our income tax expense for the first three months of 2025 increased by 4.7%, or Ps. 0.5 billion, over the first three months of 2024. This increase mainly reflects more profit before income tax.

Our effective corporate income tax rate as a percentage of profit before income tax was 37.2% for the first three months of 2025, compared to 43.8% for the first three months of 2024. This rate differs from the applicable rate of 30% under Mexican law and changed year over year mainly due to the tax effects of inflation on several of our subsidiaries.

Net Profit

We recorded a net profit of Ps. 19.7 billion for the first three months of 2025, an increase of 37.8%, or Ps. 5.4 billion, over the first three months of 2024.

Segment Results of Operations for the three-month periods ended March 31, 2025 and 2024

The following table sets forth the exchange rates used to translate the results of our most significant non-Mexican operations, as expressed in Mexican pesos per foreign currency unit, and the change from the rate used in the prior period indicated. The U.S. dollar is our functional currency in several of the countries or territories in which we or our subsidiaries operate, including Ecuador, Puerto Rico and El Salvador. Exchange rate changes between the Mexican peso and the currencies in which our subsidiaries operate affect our reported results in Mexican pesos and the comparability of reported results between periods.

Mexican pesos<br><br> <br>per foreign currency unit<br><br> <br>(average for the period)<br><br> <br>for the three-month periods<br><br> <br>ended March 31,
2024 2025 % Change
Brazilian real 3.4333 3.4910 1.7
Colombian peso 0.0043 0.0049 13.3
Argentine peso ^(1)^ 0.0204 0.0193 (5.2)
U.S. dollar 16.9980 20.4244 20.2
Euro 18.4548 21.4838 16.4
^(1)^As of March 31, 2025, the devaluation of the Argentine peso against the Mexican peso is due primarily to the economic policies established by the new<br> Argentine administration in December 2023. The stated goals of the policies involve, among other things, the devaluation of the Argentine peso by more than 20 percent of its value as observed in the three-month periods ended March 31, 2025.

Interperiod Segment Comparisons

The following discussion addresses the financial performance of each of our reportable segments by comparing results as of and for the three months ended March 31, 2024 and 2025. In the year-to-year comparisons for each segment, we include percentage changes in operating revenues, operating income and operating margin (operating income as a percentage of operating revenues), in each case calculated based on the segment financial information and prepared in accordance with IFRS 8.

Each reportable segment excludes all income, cost and expense incurred between subsidiaries within the reportable segment. The Mexico Wireless segment includes corporate income, costs and expenses.

Comparisons in the following discussion are calculated using figures in Mexican pesos. We also include percentage changes in adjusted segment operating revenues, adjusted segment operating income and adjusted operating margin (adjusted operating income as a percentage of adjusted operating revenues), which consist of segment operating revenues, segment operating income and segment operating margin, respectively, minus (i) certain intersegment transactions, (ii) for our non-Mexican segments, the effects of foreign currency translation and (iii) for the Mexican Wireless segment only, revenues and costs of group corporate activities and other businesses that are allocated to the Mexico Wireless segment. The following discussions provide a quantification of these non-IFRS measures, presented herein to the most directly comparable financial measures calculated and presented in accordance with IFRS Accounting Standards. We have provided the non-IFRS measures herein, which are not calculated or presented in accordance with IFRS Accounting Standards, as supplemental information and in addition to the financial measures that are calculated and presented in accordance with IFRS Accounting Standards.

These supplemental non-IFRS measures are presented because management has evaluated our financial results both including and excluding the adjusted items and believes that the supplemental non-IFRS measures presented provide additional perspective and insights when analyzing our core operating performance from period to period and trends in our historical operating results. These supplemental non-IFRS measures made by management, which should not be considered superior to, as a substitute for or an alternative to, should be considered in conjunction with the IFRS measures presented herein.

Except for the Southern Cone – Argentina segment, comparisons in the following discussion are calculated using figures in Mexican pesos. For the Southern Cone – Argentina segment only, due to hyperinflationary conditions in Argentina, comparisons in the following discussion are calculated using figures in constant Argentine peso terms, which are adjusted for inflation in accordance with International Accounting Standard (“IAS”) 29 Financial Reporting in Hyperinflationary Economies (“IAS 29”), and must be converted into Mexican pesos at the exchange rate observed at the end of the period per IFRS Accounting Standards, as described above under “Constant Currency Presentation”.


The tables below set forth operating revenues and operating income for each of our segments for the years indicated.

Segment operating revenues for the first three months of 2025 increased by 20.8% over the first three months of 2024. Adjusted segment operating revenues were Ps. 24.3 billion in the first three months of 2025 and Ps. 23.4 billion in the first three months of 2024, after giving effect to adjustments of Ps. (4.0) billion and Ps. 0.9 million, respectively, for intersegment transactions and the effects of foreign currency translation. This represents an increase of 3.8% in adjusted segment operating revenues in the first three months of 2025, as compared to the first three months of 2024, which principally reflects an increase in all service revenues other than prepaid and fixed voice.

Segment operating income for the first three months of 2025 increased by 21.9% over the first three months of 2024. Adjusted segment operating income was Ps. 3.2 billion in the first three months of 2025 and Ps. 3.1 billion in the first three months of 2024, after giving effect to adjustments of Ps. (0.5) billion and Ps. (2.2) million, respectively, for intersegment transactions and the effects of foreign currency translation.

Segment operating margin was 13.3% in the first three months of 2025, as compared to 13.2% in the first three months of 2024. Adjusted segment operating margin was 13.3% in the first three months of 2025, as compared to 13.2% in the first three months of 2024. This increase in adjusted segment operating margin principally reflects decreases in network maintenance and infrastructure leasing costs.

Liquidity and Capital Resources

Our management defines net debt (which is considered a non-IFRS measure) as total debt (defined as short and long-term debt) minus (i) cash and cash equivalents and (ii) equity investments available for sale at fair value through other comprehensive income (“OCI”). As of March 31, 2025, we had net debt of Ps. 499.9 billion, compared to net debt of Ps. 403.7 billion as of March 31, 2024. As of March 31, 2025, we had total debt of Ps. 588.2 billion, cash and cash equivalents of Ps. 35.3 billion, equity investments available for sale at fair value through OCI of Ps. 53.1 billion.

Without taking into account the effects of derivative financial instruments that we use to manage our interest rate and currency risk, approximately 77.6% of our indebtedness at March 31, 2025 was denominated in currencies other than Mexican pesos (approximately 44.9% of such non-Mexican peso debt was denominated in U.S. dollars and 55.1% in other currencies), and approximately 19.1% of our consolidated debt obligations bore interest at floating rates. After the effects of derivative transactions, approximately 40.5% of our net debt as of March 31, 2025 was denominated in Mexican pesos.

As of March 31, 2025, we had approximately Ps. 170.1 billion in debt and contractual obligations due in 2025, including approximately Ps. 123.0 billion of principal and amortizations, Ps. 36.3 billion in short-term lease debt, and Ps. 10.8 billion in purchase obligations.

As of March 31, 2025, we had approximately Ps. 218.0 billion in debt and contractual obligations due between 2026 and 2028, including approximately Ps. 125.4 billion of principal amortizations, Ps. 80.2 billion in long-term lease debt, and Ps. 12.4 billion in purchase obligations. As of the same date, we had approximately Ps. 186.7 billion in debt and contractual obligations due between 2029 and 2030, including approximately Ps. 98.6 billion of principal and amortization, Ps. 79.4 billion in long-term lease debt, and Ps. 8.7 billion in purchase obligations. As of the same date, we had approximately Ps. 286.7 billion in debt and contractual obligations due after 2030, including approximately Ps. 241.2 billion of principal and amortizations, Ps. 25.5 billion in long-term lease debt, and Ps. 20.0 billion in purchase obligations.

We regularly assess our interest rate and currency exchange exposures in order to determine how to manage the risk associated with these exposures. As of March 31, 2025, the net fair value of our derivatives and other financial items was a net liability of Ps. 7.7 billion.

During the first three months of 2025, we used approximately Ps. 24.7 billion to fund capital expenditures, which was primarily funded by our operating activities. We continue to evaluate our capital expenditure needs and opportunities. We have also continued to repurchase shares of our capital stock under our share repurchase program, and during the first three months of 2025, we spent Ps. 3.8 billion repurchasing our shares in the open market. Whether we continue to do so will depend on our operating cash flow and on various other considerations, including market prices and our other capital requirements.
