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.

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.

Anchor Anchor AMÉRICA MÓVIL

América Móvil, S.A.B. de C.V. (“América Móvil,” “we,” “us,” “our” or the “Company”) is a s ociedad 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 September 30, 2025, we had 328.8 million wireless voice and data subscriptions and 78.9 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);

• Central America (Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua);

• the Caribbean (the Dominican Republic and Puerto Rico); and

• Europe (Austria, Belarus, Bulgaria, Croatia, North Macedonia, Serbia and Slovenia).

Condensed Consolidated Results of Operations as of and for the Nine-Month Periods Ended September 30, 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 translated into Mexican pesos using the exchange rate at the closing date of that same period for consolidation purposes. 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 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 between us and Liberty Latin America, Ltd. (“LLA”), and therefore not consolidated with the Company) into its operations. As a result, on October 31, 2024, we converted our outstanding notes in Claro Chile, SpA into equity and began to consolidate Claro Chile, SpA into our consolidated financial statements. At the effective date of the conversion, LLA retained an approximate 9.0% interest and the Company an approximate 91.0% interest. As of December 31, 2024 and September 30, 2025, we held a 94.9% and a 100% interest in Claro Chile, SpA, respectively . The discussion and analysis in this Form 6-K presents financial measures that exclude the results of operations of Claro Chile, SpA, notwithstanding their inclusion in our consolidated financial statements. Accordingly, such financial measures that exclude the results of operations of Claro Chile, SpA constitute non-IFRS financial measures, as they omit the assets, liabilities, and operating results associated with Claro Chile, SpA’s operations. We believe this approach provides a clearer view of the financial impact resulting from the commencement of its consolidation.

Operating Revenues

Total operating revenues for the first nine months of 2025 increased by 10.5%, or Ps. 66.5 billion, over the first nine months of 2024. At constant exchange rates, total operating revenues for the first nine months of 2025 increased by 6.2% over the first nine months of 2024, or 3.7% excluding the effects of consolidating Claro Chile, SpA.

Service Revenues – Service revenues for the first nine months of 2025 increased by 10.7%, or Ps. 58.0 billion, over the first nine months of 2024. At constant exchange rates, service revenues for the first nine months of 2025 increased by 6.3% over the first nine months of 2024, or 3.7% 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 services.

Sales of Equipment – Sales of equipment revenues for the first nine months of 2025 increased by 9.4%, or Ps. 8.5 billion, over the first nine months of 2024. At constant exchange rates, sales of equipment revenues for the first nine months of 2025 increased by 6.1% over the first nine months of 2024, or 3.8% excluding the effects of consolidating Claro Chile, SpA. This increase at constant exchange rates principally reflects an increase in sales of smartphones, data-enabled devices and accessories in Colombia, Austria, Brazil and Central America.

Table of Contents

Operating Costs and Expenses

Total operating costs and expenses for the first nine months of 2025 increased by 11.6%, or Ps. 57.9 billion, over the first nine months of 2024. At constant exchange rates, total operating costs and expenses for the first nine months of 2025 increased by 7.2% over the first nine months of 2024, or 2.9% 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 network maintenance, IT services and electric energy.

Cost of Sales and Services – Cost of sales and services for the first nine months of 2025 increased by 10.2%, or Ps. 24.4 billion, over the first nine months of 2024. At constant exchange rates, cost of sales and services for the first nine months of 2025 increased by 6.5% over the first nine months of 2024, or 3.5% 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 nine months of 2025 increased by 13.5%, or Ps. 18.3 billion, over the first nine months of 2024. As a percentage of operating revenues, commercial, administrative and general expenses were 22.0% for the first nine months of 2025, compared to 21.5% for the first nine months of 2024. At constant exchange rates, commercial, administrative and general expenses for the first nine months of 2025 increased by 8.6% over the first nine months of 2024, or 4.7% 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 nine months of 2025 decreased by 7.7% or Ps. 0.4 billion over the first nine months of 2024, principally due to the reduction in expenses for site maintenance and migration to a new version of SAP at our subsidiary Telmex during the prior year.

Depreciation and Amortization – Depreciation and amortization for the first nine months of 2025 increased by 13.1%, or Ps. 15.6 billion, over the first nine months of 2024. As a percentage of operating revenues, depreciation and amortization were 19.3% for the first nine months of 2025, compared to 18.9% for the first nine months of 2024. At constant exchange rates, depreciation and amortization for the first nine months of 2025 increased by 7.8% over the first nine months of 2024, or 0.4% excluding the effects of consolidating Claro Chile, SpA.

Operating Income

Operating income for the first nine months of 2025 increased by 6.4%, or Ps. 8.6 billion, over the first nine months of 2024. Operating margin (operating income as a percentage of operating revenues) was 20.4% for the first nine months of 2025, compared to 21.1% for the first nine months of 2024.

Non-Operating Items

Net Interest Expense – Net interest expense (interest expense less interest income) for the first nine months of 2025 increased by 15.4%, or Ps. 5.3 billion, over the first nine months of 2024. This rise 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 in the first nine months of 2025.

Foreign Currency Exchange Gain (Loss), Net – We recorded a net foreign currency exchange gain of Ps. 16.1 billion for the first nine months of 2025, compared to our net foreign currency exchange loss of Ps. 58.4 billion for the first nine months of 2024. This shift can be attributed to the appreciation of the Mexican peso against the U.S. dollar, the primary currency of our debt, during 2025, which contrasts with the depreciation of the Mexican peso against the U.S. dollar in 2024.

Table of Contents

Valuation of Derivatives, Interest Cost from Labor Obligations and Other Financial Items, Net – We recorded a net loss of Ps. 10.4 billion for the first nine months of 2025 on the valuation of derivatives, interest cost from labor obligations and other financial items, net, compared to a net gain of Ps. 10.5 billion for the first nine months of 2024. The change in the first nine months of 2025 principally reflects a decrease in the net monetary position gain from our subsidiaries in Argentina.

Income Tax – Our income tax expense for the first nine months of 2025 increased by 61.9%, or Ps. 15.5 billion, over the first nine months of 2024. This increase primarily reflects higher profit before income tax, which was significantly impacted by foreign exchange gains recognized during 2025.

Our effective corporate income tax rate as a percentage of profit before income tax was 37.5% for the first nine months of 2025, compared to 53.2% for the first nine months of 2024. This rate differs from the applicable rate of 30% under Mexican law and changed year over year mainly due to tax effects of inflation and our non-deductible pensions.

Net Profit

We recorded a net profit of Ps. 67.7 billion for the first nine months of 2025, an increase of 207.4%, or Ps. 45.7 billion, over the first nine months of 2024.

Segment Results of Operations for the nine-month periods ended September 30, 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.

2024 2025 % Change
Brazilian real 3.3817 3.4546 2.2
Colombian peso 0.0044 0.0047 6.8
Argentine peso (1) 0.0200 0.0168 (16.0 )
U.S. dollar 17.7119 19.5409 10.3
Euro 19.2646 21.8202 13.3

(1) As of September 30, 2025, the devaluation of the Argentine peso against the Mexican peso is due primarily to the economic policies established by the new Argentine administration in December 2023. The stated goals of the policies involve, among other things, the devaluation of the Argentine peso by more than 40 percent of its value as observed in the nine-month periods ended September 30, 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 nine months ended September 30, 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 in the “Constant Currency Presentation” section of our 2024 Form 20-F.

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

Segment operating income for the first nine months of 2025 increased by 17.4% over the first nine months of 2024. Adjusted segment operating income was Ps. 12.6 billion in the first nine months of 2025 and Ps. 12.0 billion in the first nine months of 2024, after giving effect to adjustments of Ps. (1.6) billion and Ps. (0.1) billion, respectively, for intersegment transactions and the effects of foreign currency translation. This represents an increase of 5.0% in adjusted segment operating income in the first nine months of 2025, as compared to the first nine months of 2024.

Segment operating margin was unchanged at 15.9% in the first nine months of 2025, and the first nine months of 2024. Adjusted segment operating margin was 16.0% in the first nine months of 2025, as compared to 15.8% in the first nine months of 2024.

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 September 30, 2025, we had net debt of Ps. 453.6 billion, compared to net debt of Ps. 484.2 billion as of December 31, 2024. As of September 30, 2025, we had total debt of Ps. 550.2 billion, cash and cash equivalents of Ps. 49.8 billion, equity investments available for sale at fair value through OCI of Ps. 46.8 billion.

Without taking into account the effects of derivative financial instruments that we use to manage our interest rate and currency risk, approximately 75.3%% of our indebtedness at September 30, 2025 was denominated in currencies other than Mexican pesos (approximately 42.3% of such non-Mexican peso debt was denominated in U.S. dollars and 57.7% in other currencies), and approximately 12.6% of our consolidated debt obligations bore interest at floating rates. After the effects of derivative transactions, approximately 45.6% of our net debt as of September 30, 2025 was denominated in Mexican pesos.

The maturities of our long-term debt as of September 30, 2025, excluding debt associated with lease obligations, were as follows:

Years Amount (in millions of Mexican pesos)
2026 Ps. 28,714
2027 39,259
2028 51,731
2029 51,702
2030 48,469
2031 and thereafter 243,228
Total Ps. 463,103

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 September 30, 2025, the net fair value of our derivatives and other financial items was a net liability of Ps. 13.6 billion.

During the first nine months of 2025, we used approximately Ps. 84.9 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 nine months of 2025, we spent Ps. 10.8 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.

Note 2. Basis of Preparation of the Unaudited Interim Condensed Consolidated Financial Statements and Summary of Significant Accounting Policies and Practices

a) Basis of preparation

The accompanying unaudited interim condensed consolidated financial statements as of and for the three-month and nine-month periods ended September 30, 2025, have been prepared in conformity with International Accounting Standard No. 34, Interim Financial Reporting (“IAS 34”). The Company has prepared the unaudited interim condensed consolidated financial statements on the basis that it will continue to operate as a going concern. Management considers that there are no material uncertainties that may cast significant doubt over this assumption. Management concluded that the Company has adequate resources to continue in operational existence for the foreseeable future, and not less than 12 months from the end of the reporting period.

The accompanying interim condensed consolidated statement of financial position as of September 30, 2025, as well as the interim condensed consolidated statements of comprehensive income, for the three-month and nine-month periods ended September 30, 2025; changes in shareholders’ equity and cash flows for the nine-month periods ended September 30, 2025 and 2024, and their related disclosures included in these notes, are unaudited.

These unaudited interim condensed consolidated financial statements have been prepared using the same accounting policies as those used in the preparation of our annual consolidated financial statements as of December 31, 2024, except for the adoption of new standards and interpretations effective as from January 1, 2025.

These unaudited interim condensed consolidated financial statements do not include all the information and disclosures required in annual consolidated financial statements and should be read in conjunction with the Company’s annual consolidated financial statements as of December 31, 2024 and for the three-year period then ended, included in the Company’s annual report on Form 20-F filed with the U.S. Securities and Exchange Commission on May 14, 2025 (the “2024 Form 20-F”).

The preparation of these unaudited interim condensed consolidated financial statements in accordance with IAS 34 requires the use of critical estimates and assumptions that affect the amounts reported for certain assets and liabilities, as well as certain revenues and expenses. It also requires that management exercise judgment in the application of the Company’s accounting policies.

The Mexican peso is the functional currency of the Company’s Mexican operations and the consolidated reporting currency of the Company.

i) New standards, interpretations and amendments adopted by the Company

The Company has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

One IFRS amendment applies for the first time in 2025 but had no impact on the unaudited interim condensed consolidated financial statements of the Company.

Lack of exchangeability – Amendments to IAS 21

In August 2023, the IASB issued amendments to IAS 21 The Effects of Changes in Foreign Exchange Rates to specify how an entity should assess whether a currency is exchangeable and how it should determine a spot exchange rate when exchangeability is lacking. The amendments also require disclosure of information that enables users of its financial statements to understand how the currency not being exchangeable into the other currency affects, or is expected to affect, the entity’s financial performance, financial position and cash flows.

The amendments are effective for annual reporting periods beginning on or after January 1, 2025. When applying the amendments, an entity cannot restate comparative information.

The amendments had no impact on the Company’s unaudited interim condensed consolidated financial statements.

b) Climate-related matters

The Company considers climate-related matters where appropriate. This assessment includes a wide range of possible impacts on the Company due to both physical and transition risks. The Company has not identified an environmental nor transitional risk associated to climate change with the potential to have a significant effect in the Company’s financial performance and results of operations to date.

Fair value of derivative financial instruments is valued using valuation techniques with market observable inputs. To determine its Level 2 fair value, the Company applies different valuation techniques including forward pricing and swaps models, using present value calculations. The models incorporate various inputs including credit quality of counterparties, foreign exchange spot and forward rates and interest rate curves. Fair value of debt Level 2 has been determined using a model based on present value calculation incorporating credit quality of AMX. The Company’s investment in equity investments at fair value, specifically the investment in Verizon and BT Group are valued using the quoted prices (unadjusted) in active markets for identical assets. The net realized gain (loss) on derivative financial instruments was Ps. 3,048,499 and Ps. ( 318,021 ) for the three-month periods ended September 30, 2025 and 2024, respectively, and Ps. 6,814,778 and Ps. ( 1,410,179 ), for the nine-month periods ended September 30, 2025 and 2024, respectively.

The fair value of the revaluation of telecommunication towers was calculated using valuation techniques, using observable market data and internal information on transactions carried out with independent third parties. To determine fair value, we use level 2 and 3 information, the Company used inputs such as average rents, contract term and discount rates for discounted flow modeling techniques; in the case of discount rates, we use level 2 data where the information is public and is found in recognized databases, such as country risks, inflation, etc. In the case of level 3 data, the information is mainly internal based on lease contracts entered into with independent third parties.

As mentioned in Note 1, the Company has operations in Mexico, Guatemala, Nicaragua, Ecuador, El Salvador, Costa Rica, Brazil, Argentina, Colombia, Honduras, Peru, Paraguay, Uruguay, Chile, the Dominican Republic, Puerto Rico, Austria, Croatia, Bulgaria, Belarus, Macedonia, Serbia and Slovenia. The accounting policies for the segments are the same as those described in Note 2 on pages F-12 to F-38 of the Company’s 2024 Form 20-F .

The Chief Executive Officer, who is the Chief Operating Decision Maker (“CODM”), analyzes the financial and operating information by operating segment. All operating segments that (i) represent more than 10 % of consolidated revenues, (ii) more than the absolute amount of its reported 10 % of profits before income tax or (iii) more than 10 % of consolidated assets, are presented separately.

The Company presents the following reportable segments for the purposes of its consolidated financial statements: Mexico (includes Telcel and Corporate operations and assets), Telmex (Mexico), Brazil, Southern Cone (includes Argentina separated from Paraguay, Uruguay and Chile), Colombia, Andean (includes Ecuador and Peru), Central America (includes Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica), Caribbean (includes the Dominican Republic and Puerto Rico), and Europe (includes Austria, Bulgaria, Croatia, Belarus, Slovenia, Macedonia and Serbia).

Table of Contents

The segment Southern Cone comprises mobile communication services in Argentina as well as Paraguay, Uruguay and Chile. Beginning in 2018, hyperinflation accounting in accordance with IAS 29 was initially applied to Argentina, which results in the restatement of non-monetary assets, liabilities and all items of the statement of comprehensive income for the change in a general price index and the translation of these items applying the period-end exchange rate.

The Company considers that the quantitative and qualitative aspects of any aggregated operating segments (that is, Central America and Caribbean reportable segments) are similar in nature for all periods presented. In evaluating the appropriateness of aggregating operating segments, the key indicators considered included but were not limited to: (i) the similarity of key financial statements measures and trends, (ii) all entities provide telecommunications services, (iii) similarities of customer base and services, (iv) the methods to distribute services are the same, based on telephone plant in both cases, wireless and fixed lines, (v) similarities of governments and regulatory entities that oversee the activities and services of telecom companies, (vi) inflation trends, and (vii) currency trends.
