Basis of Preparation of the Consolidated Financial Statements and Summary of Significant Accounting Policies and Practices	Note 2. Basis of Preparation of the Consolidated Financial Statements and Summary of Significant Accounting Policies and Practices a) Basis of preparation The accompanying consolidated financial statements have been prepared in conformity with International Financial Reporting Standards, as issued by the International Accounting Standards Board (“IASB”) (hereafter referred to as IFRS). The consolidated financial statements have been prepared on the historical cost basis, except for the derivative financial instruments (assets and liabilities), the passive infrastructure of mobile telecommunications towers, the trust assets of post-employment and other employee benefit plans; debt instruments and investments in equity at fair value through other comprehensive income (OCI), which are presented at their market value. Effective July 1, 2018, the Argentine economy has been considered to be hyperinflationary in accordance with the criteria in IAS 29 “Financial Reporting in Hyperinflationary Economies” (“IAS 29”). Accordingly, for the Argentine subsidiaries, we have included adjustments for hyperinflation and reclassifications as is required by the standard for purposes of presentation of IFRS in the consolidated financial statements. The preparation of these consolidated financial statements under IFRS requires the use of critical estimates and assumptions that affect the amounts reported for certain assets, liabilities, revenue and expenses. It also requires that management exercise judgment in the application of the Company’s accounting policies. Actual results could differ from these estimates and assumptions. The Mexican peso is the functional currency of the Company’s Mexican operations and the consolidated reporting currency of the Company. i) Changes in Accounting Policies and Disclosures The accounting policies applied in the preparation of the consolidated financial statements for the year ended December 31, 2023 are consistent with those used in the preparation of the Company´s consolidated annual financial statements for the years ended December 31, 2022 and 2021, with the exception of the following new standards and amendments to existing standards issued by the IASB, which were mandatory for annual periods beginning on or after January 1, 2023: Definition of Accounting Estimates—Amendments to IAS 8 The amendments to IAS 8 clarify the distinction between changes in accounting estimates, changes in accounting policies and the correction of errors. They also clarify how entities use measurement techniques and inputs to develop accounting estimates. The amendments had no impact on the Company’s consolidated financial statements. Disclosure of Accounting Policies—Amendments to IAS 1 and IFRS Practice Statement 2 The amendments to IAS 1 and IFRS Practice Statement 2 Making Materiality Judgements provide guidance and examples to help entities apply materiality judgements to accounting policy disclosures. The amendments aim to help entities provide accounting policy disclosures that are more useful by replacing the requirement for entities to disclose their ‘significant’ accounting policies with a requirement to disclose their ‘material’ accounting policies and adding guidance on how entities apply the concept of materiality in making decisions about accounting policy disclosures. The amendments had no impact on the Company’s consolidated financial statements. Deferred Tax related to Assets and Liabilities arising from a Single Transaction – Amendments to IAS 12 The amendments to IAS 12 Income Tax The amendments had no impact on the Company’s consolidated financial statements. International Tax Reform—Pillar Two Model Rules – Amendments to IAS 12 The amendments to IAS 12 have been introduced in response to the Organisation for Economic Co-operation • A mandatory temporary exception to the recognition and disclosure of deferred taxes arising from the jurisdictional implementation of the Pillar Two model rules; and • Disclosure requirements for affected entities to help users of the financial statements better understand an entity’s exposure to Pillar Two income taxes arising from that legislation, particularly before its effective date. The mandatory temporary exception – the use of which is required to be disclosed – applies immediately. The remaining disclosure requirements apply for annual reporting periods beginning on or after 1 January 2023, but not for any interim periods ending on or before December 31, 2023. Management applied th e mand ii) Basis of consolidation The consolidated financial statements include the accounts of América Móvil, S.A.B. de C.V. and those subsidiaries over which the Company exercises control. The consolidated financial statements for the subsidiaries were prepared for the same period as the Company´s and applying consistent accounting policies. All of the subsidiary companies operate in the telecommunications sector or related. Subsidiaries are entities over which the Company has control. Control is achieved when the Company has power over the investee, when it is exposed to, or has rights to, variable returns from its involvement with the investee, and has the ability to use its power over the investee to affect the amount of the investor’s returns. Subsidiaries are consolidated on a line-by-line Changes in the Company’s ownership interests in a subsidiary that do not result in the Company losing control over the subsidiary are accounted for as equity transactions. The carrying amounts of the equity attributable to owners of the parent and non-controlling non-controlling Subsidiaries are deconsolidated from the date which control ceases. When the Company ceases to have control over a subsidiary, it derecognizes the assets (including any goodwill) and liabilities of the subsidiary at their carrying amounts, derecognizes the carrying amount of non-controlling All intra-Company balances and transactions, and any unrealized gains and losses arising from intra-Company transactions, are eliminated in preparing the consolidated financial statements. Non-controlling Non-controlling Associates: An associate is an entity over which the Company has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but does not have control or joint control over those decisions. The Company’s investment in associates includes goodwill identified on acquisition, net of any accumulated impairment losses. The investments in associated companies in which the Company exercises significant influence are accounted for using the equity method, whereby Company recognizes its share in the net profit (losses) and equity of the associate. Joint venture: A joint venture is an arrangement in which the Company has joint control, whereby the Company has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities. Interests in the joint venture are accounted for using the equity method. Pursuant to such method, the joint venture is initially recognized at cost, which includes transaction costs. Subsequent to initial recognition, the consolidated financial statements include the Company’s share of the profit or loss and OCI of equity-accounted investees, until the date on which significant influence or joint control ceases. The results of operations of the subsidiaries and associates are included in the Company’s consolidated financial statements beginning as of the month following their acquisition and its share of other comprehensive income after acquisition is recognized directly in other comprehensive income. The Company assesses at each reporting date whether there is objective evidence that investment in associates and joint venture is impaired. If so, the Company calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value. The equity interest in the most significant subsidiaries is as follows: Country Equity 2022 2023 Subsidiaries: América Móvil B.V. a) Netherlands 100.0 % 100.0 % Compañía Dominicana de Teléfonos, S.A.

The financial statements of foreign subsidiaries have been prepared under or converted to IFRS in the respective local currency (which is their functional currency) and then translated into the Company´s reporting currency as follows: • all monetary assets and liabilities were translated at the closing exchange rate of the period; • all non-monetary • equity accounts are translated at the exchange rate at the time the capital contributions were made and the profits were generated; • revenues, costs and expenses are translated at the average exchange rate of the period, except for the operations of the subsidiaries in Argentina, whose economy is considered hyperinflationary since 2018; • the consolidated statements of cash flows presented using the indirect method were translated using the weighted-average exchange rate for the applicable period (except for Argentina), and the resulting difference is shown in the consolidated statements of cash flows under the heading “Adjustment to cash flows due to exchange rate fluctuations, net”. The difference resulting from the translation process is recognized in equity in the caption “Effect of translation of foreign entities”. At December 31, 2022 and 2023, the cumulative translation adjustment was Ps. (128,299,347) and Ps. (164,975,378), respectively. The basis of translation for the operations of the subsidiaries in Argentina are described below: In recent years, the Argentina economy has shown high rates of inflation. Although inflation data has not been consistent in recent years and several indexes have coexisted, inflation in Argentina indicates that the three-year cumulative inflation rate exceeded 100% in 2018, which is one of the quantitative references established by IAS 29. As a result, Argentina was considered a hyperinflationary economy in 2018 and the Company applies hyperinflation accounting to its subsidiary whose functional currency is the Argentine peso for financial information for periods ending on or after July 1, 2018, however the calculation of the cumulative impact was measured as of January 1, 2018. In order to restate for hyperinflation its financial statements, the subsidiary used the series of indices defined by resolution JG No. 539/18 issued by the “Federación Argentina de Consejos Profesionales de Ciencias Económicas” (“FACPCE”), based on the National Consumer Price Index (IPC) published by the Instituto Nacional de Estadística y Censos (INDEC) of the Argentine Republic and the Wholesale Internal Price Index (IPIM) published by FACPCE. The cumulative index at December 31, 2023 is 3,576.400, while on an annual inflation for 2023 is 211.41%. The main implications are as follows: • Adjustment of the historical cost of non-monetary • The gain on the net monetary position caused by the impact of inflation in the year is included in the consolidated statements of comprehensive income as part of the caption “ Valuation of derivatives, interest cost from labor obligations and other financial items, net” • All items in the financial statements of the Argentine company are translated at the closing exchange rate, which at December 31, 2022 and 2023 were 0.1096 and 0.0209, respectively, per Argentine peso per Mexican peso. b) Revenue recognition The Company revenues are derived principally from providing the following telecommunications services and products: wireless voice, wireless data and value-added services, fixed voice, fixed data, broadband and IT services, Pay TV and over-the-top The Company provides fixed and mobile services. These services are offered independently in contracts with customers or together with the sale of handsets (mobile) under the postpaid model. In accordance with IFRS 15 “ Revenues from contracts with customers ” The Company with respect to the provided services, it has market observable information, to determine the standalone selling price of the services. On the other hand, in the case of the sale of bundled mobile phones sold (including service and handset) by the Company, the allocation of the sales is done based on their relative standalone selling price of each individual component related to the total bundled price. The services provided by the Company are satisfied over the time of the contract period, given that the customer simultaneously receives and consumes the benefits provided by the Company. Such service bundles, voice and data, accomplish the criteria mentioned in IFRS 15 of being substantially similar and of having the same transfer pattern which is why the Company concluded that the revenue from these different services offered to its customers are considered as a single performance obligation with revenue being recognized over time, except for sales of equipment. Under IFRS 15, for those contracts with customers in which generally the sale of equipment and other electronic equipment is a single performance obligation, the Company recognizes the revenue at the moment when it transfers control to the customer which generally occurs when such goods are delivered. The commissions are considered incremental contract acquisition costs that are capitalized and are amortized over the expected period of benefit, during the average duration of customer contracts. Some subsidiaries have loyalty programs where the Company awards credits customer credit awards referred as “points”. The customer can redeem accrued “points” for awards such as devices, accessories or airtime. The Company provides all awards. The consideration allocated to the award credits is identified as a separate performance obligation; the corresponding liability of the award credits is measured at its fair value. The consideration allocated to award credits amount is recognized as a contract liability until the points are redeemed. Revenue is recognized upon redemption of products by the customer. c) Cost of sales The cost of mobile equipment and computers is recognized at the time the client and distributor receive the device which is when the control is transferred to the customer. d) Cost of services The cost of services represents the costs incurred to properly deliver the services to the customers, it includes the network operating costs and licenses related costs and is accounted at the moment in which such services are provided. e) Commissions to distributors The Company pays commissions to its network of distributors primarily to acquire and retain customers for the Company. Such commissions are recognized in “commercial, administrative and general expenses” f) Cash and cash equivalents Cash and cash equivalents represent bank deposits and liquid investments with maturities of less than three months. These amounts are stated at cost plus accrued interest, which is similar to their market value. The Company also maintains restricted cash held as collateral to meet certain contractual obligations. As restricted cash the Company includes the judicial deposits that are presented as part of “Other assets, net” within non-current g) Equity investments at fair value through OCI and other short/long-term investments Equity investments at fair value through OCI and other short-term investments are primarily composed of equity investments and other short-term financial investments. Amounts are initially recorded at their estimated fair value. Fair value adjustments for equity investments are recorded through other comprehensive income, and other short-term investment. h) Inventories Inventories are initially recognized at historical cost and are valued using the average cost method without exceeding their net realizable value. The estimate of the realizable value of inventories on-hand i) Business combinations and goodwill Business combinations are accounted for using the acquisition method, which in accordance with IFRS 3, “ Business acquisitions (i) Identify the acquirer; (ii) Determine the acquisition date; (iii) Value the acquired identifiable assets and assumed liabilities; and (iv) Recognize the goodwill or a bargain purchase gain. For acquired subsidiaries, goodwill represents the difference between the purchase price and the fair value of the net assets acquired at the acquisition date. The investment in acquired associates includes goodwill identified on acquisition, net of any impairment loss. Goodwill is reviewed annually to determine its recoverability or more often if circumstances indicate that the carrying value of the goodwill might not be fully recoverable. The possible loss of value in goodwill is determined by analyzing the recovery value of the cash generating unit (or the group thereof) to which the goodwill is associated at the time it was originated. If this recoverable amount is lower than the carrying value, an impairment loss is charged to the results of operations. The recoverable amount is determined based on the higher of fair value less cost of disposal or value in use. For the years ended December 31, 2021, 2022 and 2023, no impairment losses were recognized for goodwill. j) Property, plant and equipment i) Property, plant and equipment are recorded at acquisition cost, net of accumulated depreciation; except for the passive infrastructure of telecommunications towers, which are recognized under the revaluation model. Depreciation is computed on the cost of assets using the straight-line method, based on the estimated useful lives of the related assets, beginning the month after they become available for use. Borrowing costs that are incurred for general financing for construction in progress for a substantial period of time are capitalized as part of the cost of the asset. During the years ended December 31, 2021, 2022 and 2023, borrowing costs that were capitalized amounted to Ps. 1,527,259, Ps. 1,514,654 and Ps. 1,442,077, respectively. In addition to the purchase price and costs directly attributable to preparing an asset in terms of its physical location and condition for operating as intended by management, when required, the cost also includes the estimated costs of dismantling and removal of the asset and for restoration of the site where it is located. See Note 16c. The passive infrastructure of telecommunications towers is recorded at revalued value, which is its fair value at the time of revaluation less accumulated depreciation; if there is any loss or impairment, it must also be considered within its value. The revaluations will be calculated with sufficient regularity to ensure that the book value, every time, does not differ significantly from that which could be determined using the fair value at the end of the reporting period. The increase resulting from a revaluation is recorded in other comprehensive income (OCI) and is accumulated in equity as a revaluation surplus. To the extent that there is a decrease in revaluation, it will be recognized in profit or loss, except to the extent that it compensates for an existing surplus on the same asset. An annual transfer of the asset revaluation surplus and accumulated earnings is made to the extent that the asset is used, therefore, the surplus is equal to the difference between the depreciation calculated on the revalued value and the one calculated according to its original cost. These transfers do not record in the results for the period. A total transfer of the surplus may be made when the entity disposes of the asset. ii) The net book value of property, plant and equipment is removed from the consolidated statements of financial position at the time the asset is sold or when no future economic benefits are expected from its use or sale. Any gains or losses on the sale of property, plant and equipment represent the difference between net proceeds of the sale and the net book value of the item at the time of sale, that are recognized as either other operating income or other operating expenses upon sale. iii) The Company periodically assesses the residual values, useful lives and depreciation methods associated with its property, plant and equipment. If necessary, the effects of any changes in accounting estimates is recognized prospectively, at the closing of each period, in accordance with IAS 8, “ Accounting Policies, Changes in Accounting Estimates and Errors For property, plant and equipment made up of several components with different useful lives, the major individual components are depreciated over their individual useful lives. Maintenance costs and repairs are expensed as incurred. Annual depreciation rates are as follows: Network infrastructure 5%-33% Buildings and leasehold improvement 2%-33% Other assets 10%-50% iv) The carrying value of property, plant and equipment is reviewed annually if there are indicators of impairment in such assets. If an asset’s recovery value is less than the asset’s net carrying value, the difference is recognized as an impairment loss. During the years ended December 31, 2021, 2022 and 2023, no impairment losses were recognized. v) Spare parts for network operation are recognized at cost. The valuation of inventory for network considered obsolete, defective or slow-moving, is reduced to their estimated net realizable value. The estimate of the recovery value of inventories is based on their age and turnover. k) Intangibles i) Licenses Licenses to operate wireless telecommunications networks granted by the governments of the countries in which the Company operates are recorded at acquisition cost or at fair value at their acquisition date, net of accumulated amortization. Certain licenses require payments to the governments, such payments are recognized in the cost of service and equipment. The licenses that in accordance with government requirements are categorized as automatically renewable, for a nominal cost and with substantially consistent terms, are considered by the Company as intangible assets with an indefinite useful life. Accordingly, they are not amortized. Licenses are amortized when the Company does not have a basis to conclude that they are indefinite lived. Other licenses are amortized using the straight-line method over a period ranging from 3 to 30 years, which represents the usage period of the assets. The Company has conducted an internal analysis on the applicability of the International Financial Reporting Interpretation Committee (“IFRIC”) No. 12 (Service Concession Agreements) and has concluded that its concessions are outside the scope of IFRIC 12. To determine the applicability of IFRIC 12, the Company analyzes each concession or group of similar concessions in a given jurisdiction. As a threshold matter, the Company identifies those government concessions that provide for the development, financing, operation or maintenance of infrastructure used to render a public service, and that set out performance standards, mechanisms for adjusting prices and arrangements for arbitrating disputes. With respect to those services, the Company evaluates whether the grantor controls or regulates (i) what services the operator must provide, (ii) to whom it must provide them and (iii) the applicable price (the “Services Criterion”). In evaluating whether the applicable government, as grantor, controls the price at which the Company provides its services, the Company looks at the terms of the concession agreement according to all applicable regulations. If the Company determines that the concession under analysis meets the Services Criterion, then the Company evaluates whether the grantor would hold a significant residual interest in the concession’s infrastructure at the end of the term of the arrangement. ii) Trademarks Trademarks acquired are measured on initial recognition at cost. The cost of trademarks acquired in a business combination is their fair value at the date of acquisition. The useful lives of trademarks are assessed as either definite or indefinite. Trademarks with finite useful lives are amortized using the straight-line method over a period ranging from 1 to 10 years. The assessment of indefinite life is reviewed annually to determine whether the indefinite life continues to be supportable, if not, the change in useful life from indefinite to definite is made on a prospective basis. iii) Irrevocable rights of use Irrevocable rights of use are recognized according to the amount paid for the right and are amortized over the period in which they are granted. The carrying values of the Company’s licenses and trademarks are reviewed annually and whenever there are indicators of impairment in the value of such assets. When an asset’s recoverable amount, which is the higher of the asset’s fair value, less disposal costs and its value in use (the present value of future cash flows), is less than the asset’s carrying value, the difference is recognized as an impairment loss. iv) Customer relationships The value of customer relations is determined and valued at the time that a new subsidiary is acquired, as determined by the Company with the assistance of independent appraisers and is amortized over a 5-year During the years ended December 31, 2021, 2022 and 2023, no significant impairment losses were recognized for licenses, trademarks, irrevocable rights of use or customer relationships. l) Impairment in the value of long-lived assets The Company assesses the existence of indicators of impairment in the carrying value of long-lived assets, goodwill and intangible assets according to IAS 36 “ Impairment of assets pre-tax In the estimation of impairments, the Company uses the strategic plans established for the separate cash-generating units to which the assets are assigned. Such strategic plans generally cover a period from 3 to 5 years. For longer periods, beginning in the fifth year, projections are based on such strategic plans while applying a constant or declining expected perpetual growth rate. Key assumptions used in value in use calculations The forecasts are made in real terms (net of inflation) and in the functional currency of the subsidiary as of December 31, 2023. Financial forecasts, premises and assumptions are similar to what any other market participant in similar conditions would consider. Local synergies, that any other market participant would not have taken into consideration to prepare similar forecasted financial information, have not been included. The assumptions used to develop the financial forecasts were validated for each of the cash generating units (“CGUs”), typically identified by country and by service (in the case of Mexico fixed and mobile) taking into consideration the following: • Current subscribers and expected growth; • Type of subscribers (prepaid, postpaid, fixed line, multiple services); • Market environment and penetration expectations; • New products and services; • Economic environment of each country; • Expenses for maintaining the current assets; • Investments in technology for expanding the current assets; and • Market consolidation and synergies. The foregoing forecasts could differ from the results obtained through time; however, the Company prepares its estimates based on the current situation of each of the CGUs. The recoverable amounts are based on value in use. The value in use is determined based on the method of discounted cash flows. The key assumptions used in projecting cash flows are: • Margin on EBITDA is determined by dividing EBITDA (operating income plus depreciation and amortization) by total revenues. • Margin on CAPEX is determined by dividing capital expenditures (“CAPEX”) by total revenues. • Post-tax As discount rate, the Company uses the WACC which was determined for each of the cash generating units and is described in the following paragraphs. The estimated discount rates to perform the IAS 36 “ Impairment of assets The discount rates represent the current market assessment of the risks specific to each CGU, taking into consideration the time value of money and individual risks of the underlying assets that have not been incorporated in the cash flow estimates. The discount rate calculation is based on the specific circumstances of the Company and its operating segments. The WACC takes into account both debt and equity costs. The cost of equity is derived from the expected return on investment for each GCU. The cost of debt is based on the interest-bearing borrowings the Company is obliged to service. Segment-specific risk is incorporated by applying individual beta factors. The beta factors are evaluated annually based on publicly available market data. Market participant assumptions are important because, not only do they include industry data for growth rates, but also management assesses how the CGU’s position, relative to its competitors, might change over the forecasted period. The most significant forward-looking estimates used for the 2022 and 2023 impairment evaluations are shown below: Average margin on Average margin on Average pre-tax 2022: Europe (7 countries) 32.70% - 47.31% 7.7% - 21.1% 5.47% - 24.11% Brazil (fixed line, wireless and TV) 41.90% 19.62% 9.30% Puerto Rico 26.98% 8.91% 6.14% Dominican Republic 53.93% 13.82% 11.13% Mexico (fixed line and wireless) 36.19% 18.61% 8.60% Ecuador 47.14% 18.42% 20.13% Peru 36.53% 21.05% 10.39% El Salvador 45.18% 17.59% 22.37% Colombia 42.25% 27.41% 13.70% Other countries 32.92% - 49.54% 9.63% - 25.97% 9.16% - 29.94% 2023: Europe (7 countries) 26.81% - 43.90% 4.46% - 16.89% 6.08% - 29.15% Brazil (fixed line, wireless and TV) 43.07% 14.37% 10.45% Puerto Rico 23.92% 10.46% 6.31% Dominican Republic 52.34% 13.78% 11.95% Mexico (fixed line and wireless) 36.10% 10.66% 9.37% Ecuador 50.81% 18.49% 21.77% Peru 41.80% 7.11% 9.13% El Salvador 46.27% 9.26% 20.15% Colombia 43.39% 20.78% 10.15% Other countries 28.06% - 51.46% 11.68% - 27.15% 10.29% - 22.79% Sensitivity to changes in assumptions: The implications of the key assumptions for the recoverable amount are discussed below: Margin on CAPEX- The Company performed a sensitivity analysis by increasing its CAPEX by 5% and maintaining all other assumptions the same. The sensitivity analysis would require the Company to adjust the amount of its long-lived assets in one of its CGUs with potential impairment of approximately Ps. 1,208,795. WACC- Additionally, should the Company increase by 50 base points in WACC per CGU and maintain all other assumptions the same. The sensitivity analysis would require the Company to adjust the amount of its long-lived assets in one of its CGUs with potential impairment of approximately Ps. 1,235,848. m Right

This relates to the difference between the actual depreciation and equivalent depreciation based on cost. A reconciliation of the statutory income tax rate in Mexico to the consolidated effective income tax rate recognized by the Company is as follows: Year ended December 31, 2021 2022 2023 Statutory income tax rate in Mexico 30.0 % 30.0 % 30.0 % Impact of non-deductible and non-taxable items: Tax inflation effects 7.8 % 7.2 % 2.1 % Derivatives (0.9 %) (0.2 )% 0.3 % Employee benefits 2.6 % 2.0 % 1.5 % Other (2.9 %) 2.2 % 4.8 % Effective tax rate on Mexican operations 36.6 % 41.2 % 38.7 % Tax recoveries and NOL’s in Brazil (10.6 %) (2.2 )% (3.5 )% Dividends received from associates equity (0.7 )% (0.1 )% —  Foreign subsidiarie 8.7 % (1) (2.6 )% (2.2 )% Tax rates differences (2.8 )% (2.0 )% (3.1 )% Effective tax rate from continuing operations 31.2 % 34.3 % 29.9 % Effective tax rate from discontinued operations (16.4 )% (21.2 )% —  (1) Includes discontinued operations effects of TracFone and Claro Chile The breakdown of net deferred tax assets is as follows: Consolidated statements of financial position Consolidated statements of net income 2022 2023 2021 2022 2023 Provisions Ps. 18,813,454 Ps. 29,562,781 Ps. 1,812,523 Ps. 1,759,784 Ps. 15,065,996 Deferred revenues 8,153,287 8,691,188 2,202,413 (688,767 ) 1,767 Tax losses carry forward 33,314,653 36,970,123 5,571,115 1,202,546 8,575,209 Property, plant and equipment (1) (18,840,025 ) (8,699,418 ) 8,016,244 1,696,734 2,157,776 Inventories 405,489 1,054,611 852,888 253,932 669,382 Licenses and rights of use (1) (2,630,583 ) (2,621,672 ) 480,502 229,244 141,060 Employee benefits 36,662,123 34,663,794 (354,802 ) (6,148,504 ) (3,224,333 ) Other 22,537,353 16,993,113 (3,545,542 ) 3,150,479 (9,576,577 ) Net deferred tax assets Ps. 98,415,751 Ps. 116,614,520 Deferred tax benefit in net profit for the year Ps. 15,035,341 Ps. 1,455,448 Ps. 13,810,280 Deferred tax from discontinued operations 4,731,603 1,808,298 —  (1) As of December 31, 2022 and 2023, the balance included the effects of hyperinflation and revaluation of telecommunications towers.

The Company does not recognize a deferred tax liability related to the undistributed earnings of its subsidiaries, because it currently does not expect these earnings to be taxable or to be repatriated in the near future. The Company’s policy has been to distribute the profits when it has paid the corresponding taxes in its home jurisdiction and the tax can be accredited in Mexico. The temporary differences associated with investments in the Group’s subsidiaries, associates and joint venture, for which a deferred tax liability has not been recognized in the periods presented, aggregate to Ps 187,830,823 and Ps. 167,222,681 as of December 31, 2022 and 2023, respectively. At December 31, 2022 and 2023, the balance of the contributed capital account (“CUCA”) is Ps. 654,631,901 and Ps. 680,304,268 respectively. Effectively, on January 1, 2014, the Cuenta de Utilidad Fiscal Neta During 2021, America Móvil sold 100% of its participation in Tracfone Wireless, Inc (Tracfone), virtual operator of the most important mobile prepaid services in USA to Verizon Communications Inc. (“Verizon”), tax profit of this transaction was Ps. 93,968,555. ii) Significant foreign income tax matters a) The foreign subsidiaries determine their taxes on profits based on their individual taxable income, in accordance with the specific tax regimes of each country. The effective income tax rate for the Company’s foreign jurisdictions was 19.3% in 2021, 17.4% in 2022 and 13.9% in 2023. The statutory tax rates in these jurisdictions vary, although many approximate 10% to 35%. The primary difference between the statutory rates and the effective rates in 2021, 2022 and 2023 was attributable to dividends received from KPN, other non-deductible items, non-taxable income and tax recoveries in Brazil and registry of benefits related to tax losses credits in Brazil. a.1 Given the more likely than not position of success of this lawsuit as consequence of the decision, with general repercussion, of the STF, Brazil updated its analysis, support documentation and forecast and recorded Ps. 2,647,919 (R$703,761) of which Ps. 2,076,594 (R$551,915) represent an excess on deferred IRPJ and CSLL and Ps. 571,325 (R$151,846) represent an excess on current IRPJ and CSLL. The subsidiaries are waiting for the necessary procedural steps to continue, to start the compensation of such amounts. a.2) a.3) Among the measures adopted macroeconomically, are the following: • The Central Bank has made access to the free exchange market for goods and services imports more flexible, eliminating bureaucratic and administrative obstacles which obstructed access to foreign currency. This is the reason for the establishment of differentiated payment terms, according to the nature of the imported goods and services. • The implementation of a new tax amnesty is under analysis, which will include both business subjects and individuals, and a regularization for the payment of tax, customs, and social security debts accrued as of December 31, 2023, releasing interest and penalties. iii)  Tax losses a) At December 31, 2023, the available tax loss carryforwards recorded in deferred tax assets are as follows on a country by country basis: Country Gross balance Tax-effected Brazil Ps. 74,392,065 Ps. 25,293,302 Mexico 25,515,213 7,654,564 Argentina 10,750,889 3,762,811 Others 864,821 259,446 Total Ps. 111,522,988 Ps. 36,970,123 b) bi) The Company believes that it is more likely than not that the accumulated balances of its net deferred tax assets are recoverable, based on the positive evidence of the Company to generate future taxable income related to the same taxation authority which will result in taxable amounts against which the available tax losses can be utilized before they expire. bii) biii) iv)  Optional regime The Mexican Tax Law establishes an optional regime for group companies called: Optional Regime for Groups of Companies. For these purposes, the integrating (controlling) company must own more than 80% of the shares with voting rights of the integrated (controlled) companies. In general terms, the Integration regime allowed deferral, for each of the companies that make up the group, and for up to three years, or sooner if certain assumptions are made, the whole of the income tax that results from considering the determination of the individual income tax to its charge is the effect derived from recognizing, indirectly, the tax losses incurred by the companies in the group for the year in question. On December 19, 2019, the integrating company submitted to the Mexican tax authorities, the notice to end to belong under the Optional Regime for Groups of Companies, which implied a payment made in January 2020 related to the deferred income tax for the years 2016-2018. From the year 2020, the group is taxable under the General Regime for Legal Persons. v) Limiting interest deductions The Mexican Tax Law establishes since 2020 new rules related to the limit on interest deductions, in concordance with the action 4 of BEPS project issued by the OECD, from which Mexico is member. In general terms, each Mexican companies should calculate an adjusted Tax EBITDA, whose amount times the corporate income tax, will be the interest limit allowed to be deducted in each tax year. It is important to mention that the amount that was not deductible could be carryforward in the following ten years. vi) Revaluation of telecommunications towers Deferred taxes related to the revaluation of the passive infrastructure of the telecommunications towers have been calculated at the tax rate of the jurisdiction in which the subsidiaries are located.

The Company’s weighted average cost of borrowed funds as of December 31, 2022, and December 31, 2023 was approximately 5.38% and 5.94%, respectively. Such rates do not include commissions or the reimbursements for Mexican tax withholdings (typically a tax rate of 4.9%) that the Company must pay to international lenders. An analysis of the Company’s short-term debt maturities as of December 31, 2022, and December 31, 2023, is as follows: 2022 2023 Obligations and Senior Notes Ps. 36,698,853 Ps. 95,821,829 Lines of credit 65,325,561 65,141,774 Subtotal short term debt Ps. 102,024,414 Ps. 160,963,603 Weighted average interest rate 8.50 % 7.01 % The Company’s long-term debt maturities are as follows: Years Amount 2025 Ps. 14,573,986 2026 29,974,291 2027 14,095,366 2028 40,787,112 2029 16,893,500 2030 and thereafter 223,389,194 Total Ps. 339,713,449 (i) Senior Notes The outstanding Senior Notes as of December 31, 2022, and December 31, 2023, are as follows: Currency* 2022 2023 U.S. dollars Ps. 164,945,155 Ps. 143,528,274 Mexican pesos 53,554,397 89,926,765 Euros 129,358,533 111,553,842 Pound sterling 51,608,257 47,315,652 Brazilian reais 33,673,729 28,788,006 Japanese yens 1,924,847 1,557,115 Chilean pesos 3,964,099 3,541,257 * Thousands of Mexican pesos * Includes secured and unsecured senior notes. In July 2023, under a Mexican Global Note program, the Company issued Ps. 17,000 million, sustainable bond with a coupon of 9.50%—approximately one billion U.S. dollars equivalent—maturing in January 2031. Such program was launched due to America Movil’s plan to increase Mexican pesos denominated liabilities on its consolidated statement of financial position. Global Notes are registered before SEC in U.S.A. and CNBV in Mexico. In addition, under the Company Domestic Senior Notes program, AMX issued Ps. 15,446 million notes divided in four tranches. This Notes bear a fixed or floating interest rate established as a percentage of TIIE. In addition, the Company re-opened an inflation linked Domestic Senior Note of Ps.3,150 million. (ii) Commercial Paper In August 2020, we established a new Euro-Commercial Paper program for a total amount of €2,000 million. As of December 31, 2023, debt under this program aggregated to Ps. 9,511 million. In December 2023, we updated our Mexican Domestic Senior Notes program mentioned above to include short-term issuances, and increased the program amount up to Ps. 100,000 million. As of December 31, 2023, short-term debt under this program aggregated to Ps. 200 million. (iii) Lines of credit As of December 31, 2022, and December 31, 2023, debt under lines of credit aggregated to Ps. 71,560 million and Ps. 74,466 million, respectively. Telekom Austria closed December 31, 2023 with an aggregated debt of Ps. 10,443 under lines of credit. The Company has two revolving syndicated credit facilities, one for the Euro equivalent of U.S. $1,500 million and the other for U.S. $2,500 million maturing in 2026 and 2024, respectively. As long as the facilities are committed, a commitment fee is paid. As of December 31, 2023, these credit facilities are undrawn. Telekom Austria has an undrawn revolving syndicated credit facility in Euros for €1,000 million that matures in 2026. Restrictions A portion of the debt is subject to certain restrictions with respect to maintaining certain financial ratios, as well as restrictions on selling a significant portion of groups of assets, among others. As of December 31, 2023, the Company was in compliance with all these requirements. A portion of the debt is also subject to early maturity or repurchase at the option of the holders in the event of a change in control of the Company, as defined in each instrument. The definition of change in control varies from instrument to instrument; however, no change in control shall be considered to have occurred as long as its current shareholders continue to hold the majority of the Company’s voting shares. Covenants In conformity with the credit agreements, the Company is obliged to comply with certain financial and operating commitments. Such covenants limit in certain cases, the ability of the Company or the guarantor to: pledge assets, carry out certain types of mergers, sell all or substantially all of its assets, and sell control of Telcel. Such covenants do not restrict the ability of AMX’s subsidiaries to pay dividends or other payment distributions to AMX. The more restrictive financial covenants require the Company to maintain a consolidated ratio of debt to EBITDA (defined as operating income plus depreciation and amortization) that does not exceed 4 to 1, and a consolidated ratio of EBITDA to interest paid that is not below 2.5 to 1 (in accordance with the clauses included in the credit agreements). Several of the financing instruments of the Company may be accelerated, at the option of the debt holder in the case that a change in control occurs. As of December 31, 2023, the Company was in compliance with all the covenants.

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Text block [abstract]
Commitments and Contingencies	Note 17. Commitments and Contingencies a) Commitments The Company and its subsidiaries have commitments that mature on different dates, related to committed capital expenditures. As of December 31, 2023, the total amounts equivalent to the contract period are detailed below: Year ended December 31, 2024 Ps.1,144,381 2025 10,139,691 2026 4,174,446 2027 5,379,609 2028 and 2029 16,306,828 2030 and thereafter 27,706,549 Total Ps.64,851,504 b) Provisions and Contingencies Contingencies In each of the countries in which we operate, we are party to legal proceedings in the ordinary course of business. These proceedings include tax, labor, antitrust, contractual matters and administrative and judicial proceedings concerning regulatory matters regarding interconnection and tariffs. The following is a description of our material legal proceedings. (1) Telcel Mobile Termination Rates The mobile termination rates between Telcel and other network operators have been the subject of various legal proceedings. With respect to interconnection fees for the years 2018—2024, Telcel has challenged the applicable resolutions and final resolutions are pending. Given that the “zero rate” that prevented Telcel from charging termination rates in its mobile network was held unconstitutional by the Supreme Court (Suprema Corte de Justicia de la Nación or “SCJN”), the IFT has determined asymmetric interconnection rates for the termination of traffic in Telcel’s and other operators’ networks for 2018, 2019, 2020, 2021, 2022, 2023 and 2024. The resolutions setting such rates have been challenged by Telcel, and final resolutions are pending. The Company expects that mobile termination rates, as well as other rates applicable to mobile interconnection (such as transit), will continue to be the subject of litigation and administrative proceedings. The Company cannot predict when or how these disputes will be resolved or the financial effects of any such resolutions. (2) Telcel Class Action Lawsuit A class action lawsuit was filed against Telcel by customers allegedly affected by Telcel’s quality of service and wireless and broadband rates continues in process. At this stage, the Company cannot assess whether this class action lawsuit could have an adverse effect on the Company’s business and results of operations in the event that it is resolved against Telcel, due to uncertainty about the factual and legal claims underlying this proceeding. Consequently, the Company has not established a provision in the accompanying consolidated financial statements for an eventual loss arising from this proceeding. (3) IFT Proceedings Against Telmex In 2018, the IFT imposed a fine of Ps. 2,543,937 on Telmex relating to a sanction procedure triggered by the alleged breach in 2013 and 2014 of certain minimum quality goals for dedicated link services. Telmex obtained a favorable resolution in the first instance and the appeal filed by the IFT is pending resolution. (4) Brazilian Tax Matters As of December 31, 2023, certain Company’s Brazilian subsidiaries had aggregate tax contingencies of Ps.123,637,128 (R$35,431,641) for which the Company has established provisions of Ps. 20,725,637 (R$ 5,939,505) in the accompanying consolidated financial statements for eventual losses arising from contingencies that the Company considers probable. The most significant matters for which provisions have been established are: • Ps. 39,637,229 (R$11,359,145) aggregate contingencies and Ps. 5,314,821 (R$1,523,109) provisions related to value-added tax (Imposto sobre a Circulação de Mercadorias e Prestação de Serviços or “ICMS”) assessments; • Ps. 5,962,223 (R$1,708,640) aggregate contingencies and Ps. 3,502,153 (R$1,003,639) provisions related to social contribution on net income (Contribuição Social sobre o Lucro Líquido or “CSLL”) and corporate income tax (Imposto de Renda sobre Pessoa Jurídica or “IRPJ”) assessments; • Ps. 17,376,221 (R$4,979,637) aggregate contingencies and Ps. 5,749,593 (R$1,647,705) provisions related to the social integration program (Programa de Integração Social or “PIS”) and the contribution for social security financing (Contribuição para o Financiamento da Seguridade Social or “COFINS”) assessments; • Ps. 5,965,336 (R$1,709,532) aggregate contingencies and Ps.135,398 (R$38,802) provisions related to offset’s rejections of tax credits related to Income Tax (Imposto de Renda Pessoa Jurídica o “IRPJ”) and Social Contributions over Profits (Contribuição Social sobre o Lucro Líquido o “CSLL”), arising from non-appealable judicial resolutions, mainly; • Ps. 13,754,400 (R$3,941,704) aggregate contingencies and Ps.1,443,933 (R$413,799) provisions mainly related to an allegedly improper exclusion of interconnection revenues and costs from the basis used to calculate Fund for Universal Telecommunication Services (Fundo de Universalização dos Serviços de Telecomunicações or “FUST”) obligations, which are being contested; • Ps. 6,230,607 (R$1,785,553) aggregate contingencies and Ps. 450 (R$129) provisions related to an alleged underpayment of obligations to the Telecommunications Technology Development Fund (Fundo para o Desenvolvimento Tecnológico das Telecomunicações or “FUNTTEL”), which are being challenged and for which a final resolution is pending; • Ps. 2,139,175 (R$613,040) aggregate contingencies and Ps. 45,304 (R$12,983) provisions related to the alleged nonpayment of Services Tax (Imposto Sobre Serviços or “ISS”) over several communication services, including Pay TV services, considered taxable for ISS by the Municipal Revenue Services, which are being challenged and for which a final resolution is pending; • Ps. 4,757,143 (R$1,363,291) aggregate contingencies and Ps. 134,229 (R$38,467) provisions arising from, among other, things the alleged underpayment of IRRF and CIDE taxes and on remittances made to foreign operators as remuneration for completing international calls abroad (outgoing traffic); and • Ps. 4,431,497 (R$1,269,968) aggregate contingencies and Ps. 4,106,726 (R$1,176,896) provisions related to the requirement to contribute to the Promotion of Public Radio Broadcasting (“EBC”). In addition, the Company’s Brazilian subsidiaries are subject to a number of contingencies for which it has not established provisions in the accompanying consolidated financial statements because the Company does not consider the potential losses related to these contingencies to be probable. These include Ps. 21,754,988 (R$6,234,494) related to an unpaid installation inspection rate (Taxa de Fiscalização de Instalação or “TFI”) allegedly due to the renovation of radio base stations, which is being challenged on the basis that there was no new equipment installation that could have led to this charge, along with any unpaid functioning inspection rate (Taxa de Fiscalização de Funcionamento or “TFF”). (5) Anatel Challenge to Inflation Adjustments Anatel has challenged the calculation of inflation-related adjustments due under the concession agreements with Tess S.A. (“Tess”), and Algar Telecom Leste S.A. (“ATL”), two of the Company’s subsidiaries that were previously merged into Claro S.A. Anatel rejected Tess and ATL’s calculation of the inflation-related adjustments applicable to 60% of the concessions price (which was due in three equal annual installments, subject to inflation-related adjustments and interest), claiming that the companies’ calculation of the inflation related adjustments resulted in a shortfall of the installment payments. The companies filed declaratory and consignment actions seeking the resolution of the disputes and have obtained injunctions from the Federal Court of Appeal suspending any payment until the pending appeals are resolved. After certain unfavorable resolutions issued by the Federal Court of Appeals to the appeals filed by such companies, new appeals have been filed before the Superior Court of Appeals for which definitive resolutions are pending. The amount of the alleged shortfall as well as the method used to calculate monetary corrections are in dispute. If other methods or assumptions are applied, the amount may increase. In 2022, Anatel calculated the monetary correction in a total amount of Ps. 14,579,000 (R$4,178,000). As of December 31, 2023, the Company has established a provision of Ps. 5,203,092 (R$1,491,090) in the accompanying consolidated financial statements for the losses arising from these contingencies, which the Company considers probable.

(21,708,327 ) Health care cost trend rat Ps. (432,588 ) Ps. 495,862 Telmex Plans Part of the Telmex´s employees are covered under defined benefit pension plans and seniority premiums. Pension benefits and seniority premiums are determined on the basis in their final year of employment, their seniority, and their age at the time of retirement. Telmex has set up an irrevocable trust fund to finance these employee benefits and has adopted the policy of making contributions to such fund when it is considered necessary. Europe Defined benefit pension plans A1 Telekom Austria Group provides defined benefits for certain former employees in Austria. All eligible employees are retired and were employed prior to January 1, 1975. This unfunded plan provides benefits based on a percentage of salary and years employed, not exceeding 80% of the salary before retirement, and taking into consideration the pension provided by the social security system. A1 Telekom Austria Group is exposed primarily to the risk of development of life expectancy and inflation because the benefits from pension plans are lifetime benefits. Furthermore, the obligation for pensions relate to the employees of the company Akenes in Lausanne are included. Service awards Civil servants and certain employees (in the following “employees”) are eligible to receive service awards. In accordance with the legal regulations, eligible employees receive a cash bonus of two months’ salary after 25 years of service and four months’ salary after 40 years of service. Employees with at least 35 years of service when retiring (at the age of 65) or who are retiring based on specific legal regulations are also eligible to receive the service award of four monthly salaries. The obligation is accrued over the period of service, taking into account the employee turnover rate for employees who leave employment prematurely. The main risk that A1 Telekom Austria Group is exposed to is the risk of development of salary increases and changes of interest rates. Severance Defined contribution plans Employees who started work for A1 Telekom Austria Group in Austria on or after January 1, 2003 are covered by a defined contribution plan. In 2023, A1 Telekom Austria Group paid Ps. 74,994 (2022: Ps. 66,700), 1.53% of the salary or wage, into this defined contribution plan (BAWAG Allianz Mitarbeitervorsorgekasse AG). Defined benefit plans Severance benefit obligations for employees, whose employment commenced before January 1, 2003, excluding civil servants, are covered by defined benefit plans. Upon termination of employment by A1 Telekom Austria Group or upon retirement, eligible employees receive severance payments. Depending on their time in service, their severance amounts to a multiple of their monthly basic compensation plus variable components such as overtime or bonuses, up to a maximum of twelve monthly salaries. In case of death, the heirs of eligible employees receive 50% of the severance benefits. The primary risks to A1 Telekom Austria Group are salary increases and changes of interest rates. b) Defined Contribution Plans Brazil Claro makes contributions to the DCP through Embratel Social Security Fund – Telos. Contributions are computed based on the salaries of the employees, who decide on the percentage of their contributions to the plan (participants enrolled before October 31st, 2014 is from 1% to 8% and, for those subscribed after that date, the contribution is from 1% to 7% of their salaries). Claro contributes the same percentage as the employee, capped at 8% of the participant’s balance for the employees that are eligible to participate in this plan. At December 31, 2022 and 2023, the balance of the DCP liability was Ps. 34,775 and Ps. 320,904 respectively. For the years ended December 31, 2021, 2022 and 2023 the cost of labor were Ps. 61,649, Ps. 5,021 and Ps. 3,846, respectively. Europe In Austria, pension benefits are generally provided by the social security system for employees, and by the government for civil servants. The contributions of 12.55% of gross salaries that A1 Telekom Austria Group made in 2023 to the social security system and the government in Austria amount to Ps. 1,105,037, (2022: Ps. 1,272,331). In 2023, contributions of the foreign subsidiaries into the respective systems range between 7% and 28% of gross salaries and amount to Ps. 560,777, (2022: Ps. 597,710). Additionally, A1 Telekom Austria Group offers a defined contribution plan for employees of some of its Austrian subsidiaries. A1 Telekom Austria Group’s contributions to this plan are based on a percentage of the compensation not exceeding 5%. In 2023, the annual expenses for this plan amounted to Ps. 199,345, (2022: Ps. 252,980). As of December 31, 2022 and 2023, the liability related to this defined contribution plan amounted to Ps. 55,937 and Ps. 56,692, respectively. Other countries For the rest of the countries where the Company operates and that do not have defined benefit plans or defined contribution plans, the Company makes contributions to the respective governmental social security agencies which are recognized in results of operations as they are incurred. c) Long-term direct employee benefits Balance at Effect of Increase of Payments Balance at Long-term direct employee benefits Ps.7,925,846 Ps.(879,484) Ps.1,376,566 Ps.(2,019,176) Ps.6,403,752 Balance at Effect of Increase of Payments Balance at Long-term direct employee benefits Ps.6,403,752 Ps.(647,033) Ps.1,608,275 Ps.(1,975,199) Ps.5,389,795 In 2008, a comprehensive restructuring program was initiated in the segment Austria. The provision for restructuring includes future compensation of employees who will no longer provide services for A1 Telekom Austria Group but who cannot be laid off due to their status as civil servants. These employment contracts are onerous contracts under IAS 37, as the unavoidable cost related to the contractual obligation exceeds the future economic benefit. The restructuring program also includes social plans for employees whose employment will be terminated in a socially responsible way. In 2009 and every year from 2011 to 2020, new social plans were initiated that provide for early retirement, special severance packages and golden handshake options. Due to their nature as termination benefits, these social plans are accounted for according to IAS 19.

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 fair value of VTR bonds in AMX B.V. as debt instruments at fair value through OCI, were classified as Level 1 in order they are guaranteed with shares listed on the regulated market. The Company’s investment in equity investments at fair value, specifically the investment in KPN N.V. and Verizon, is valued using the quoted prices (unadjusted) in active markets for identical assets. The net realized loss related to derivative financial instruments for the years ended December 31, 2022 and 2023 was Ps. (2,353,920) and Ps. (9,420,419) respectively. The fair value of the asset revaluation 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 average rents and contract terms, we use level 3 data, where the information is mainly internal based on lease contracts entered into with independent third parties. During the end of the period ended December 31, 2022 and 2023, there were no transfers between the Level 1, Level 2 and Level 3 fair value measurement hierarchies.

Segments	Note 23. Segments América Móvil operates in different countries. 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, the Dominican Republic, Puerto Rico, Austria, Croatia, Bulgaria, Belarus, Macedonian, Serbia and Slovenia. The accounting policies for the segments are the same as those described in Note 2. 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 and Uruguay), 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). The segment Southern Cone comprises mobile communication services, in Argentina as well as Paraguay and Uruguay. 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.

Recently Issued Accounting Standards	Note 24. Recently Issued Accounting Standards New and amended standards and interpretations The Company applied for the first-time certain standards and amendments, which are effective for annual periods beginning on or after January 1, 2023 (unless otherwise stated). The Company has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective. Amendments to IFRS 16: Lease Liability in a Sale and Leaseback In September 2022, the IASB issued amendments to IFRS 16 to specify the requirements that a seller-lessee uses in measuring the lease liability arising in a sale and leaseback transaction, to ensure the seller-lessee does not recognize any amount of the gain or loss that relates to the right of use it retains. The amendments are effective for annual reporting periods beginning on or after January 1, 2024 and must applied retrospectively to sale and leaseback transactions entered into after the date of initial application of IFRS 16. Earlier application is permitted and that fact must be disclosed. The amendments are not expected to have a material impact on the Company’s consolidated financial statements. Amendments to IAS 1: Classification of Liabilities as Current or Non-current In January 2020 and October 2022, the IASB issued amendments to paragraphs 69 to 76 of IAS 1 to specify the requirements for classifying liabilities as current or non-current. The amendments clarify: • What is meant by a right to defer settlement; • That a right to defer must exist at the end of the reporting period; • That classification is unaffected by the likelihood that an entity will exercise its deferral right; and • That only if an embedded derivative in a convertible liability is itself an equity instrument would the terms of a liability not impact its classification. In addition, a requirement has been introduced to require disclosure when a liability arising from a loan agreement is classified as non-current and the entity’s right to defer settlement is contingent on compliance with future covenants within twelve months. The amendments are effective for annual reporting periods beginning on or after January 1, 2024 and must be applied retrospectively. The Company is currently assessing the impact the amendments will have on current practice. Supplier Finance Arrangements – Amendments to IAS 7 and IFRS 7 In May 2023, the IASB issued amendments to IAS 7 Statement of Cash Flows and IFRS 7 Financial Instruments: Disclosures to clarify the characteristics of supplier finance arrangements and require additional disclosure of such arrangements. The disclosure requirements in the amendments are intended to assist users of consolidated financial statements in understanding the effects of supplier finance arrangements on an entity’s liabilities, cash flows and exposure to liquidity risk. The amendments will be effective for annual reporting periods beginning on or after January 1, 2024. Early adoption is permitted, but will need to be disclosed. The amendments are not expected to have a material impact on the Company’s consolidated financial statements. The Enhancement and Standardization of Climate-Related Disclosures for Investors On March 6, 2024, the Securities and Exchange Commission (SEC) issued the final rule on The Enhancement and Standardization of Climate-Related Disclosures for Investors. This rule mandates the disclosure of information regarding a registrant’s climate-related risks that have materially impacted, or are reasonably likely to have a material impact on, its business strategy, results of operations, or financial condition. On April 4, 2024, the SEC issued an order staying the rule’s enforcement. The Company is assessing the impact of this rule and the stay for disclosure to investors.

Basis of Preparation of the Consolidated Financial Statements and Summary of Significant Accounting Policies and Practices (Policies)	12 Months Ended
	Dec. 31, 2023
Text block [abstract]
Basis of preparation	a) Basis of preparation The accompanying consolidated financial statements have been prepared in conformity with International Financial Reporting Standards, as issued by the International Accounting Standards Board (“IASB”) (hereafter referred to as IFRS). The consolidated financial statements have been prepared on the historical cost basis, except for the derivative financial instruments (assets and liabilities), the passive infrastructure of mobile telecommunications towers, the trust assets of post-employment and other employee benefit plans; debt instruments and investments in equity at fair value through other comprehensive income (OCI), which are presented at their market value. Effective July 1, 2018, the Argentine economy has been considered to be hyperinflationary in accordance with the criteria in IAS 29 “Financial Reporting in Hyperinflationary Economies” (“IAS 29”). Accordingly, for the Argentine subsidiaries, we have included adjustments for hyperinflation and reclassifications as is required by the standard for purposes of presentation of IFRS in the consolidated financial statements. The preparation of these consolidated financial statements under IFRS requires the use of critical estimates and assumptions that affect the amounts reported for certain assets, liabilities, revenue and expenses. It also requires that management exercise judgment in the application of the Company’s accounting policies. Actual results could differ from these estimates and assumptions. The Mexican peso is the functional currency of the Company’s Mexican operations and the consolidated reporting currency of the Company. i) Changes in Accounting Policies and Disclosures The accounting policies applied in the preparation of the consolidated financial statements for the year ended December 31, 2023 are consistent with those used in the preparation of the Company´s consolidated annual financial statements for the years ended December 31, 2022 and 2021, with the exception of the following new standards and amendments to existing standards issued by the IASB, which were mandatory for annual periods beginning on or after January 1, 2023: Definition of Accounting Estimates—Amendments to IAS 8 The amendments to IAS 8 clarify the distinction between changes in accounting estimates, changes in accounting policies and the correction of errors. They also clarify how entities use measurement techniques and inputs to develop accounting estimates. The amendments had no impact on the Company’s consolidated financial statements. Disclosure of Accounting Policies—Amendments to IAS 1 and IFRS Practice Statement 2 The amendments to IAS 1 and IFRS Practice Statement 2 Making Materiality Judgements provide guidance and examples to help entities apply materiality judgements to accounting policy disclosures. The amendments aim to help entities provide accounting policy disclosures that are more useful by replacing the requirement for entities to disclose their ‘significant’ accounting policies with a requirement to disclose their ‘material’ accounting policies and adding guidance on how entities apply the concept of materiality in making decisions about accounting policy disclosures. The amendments had no impact on the Company’s consolidated financial statements. Deferred Tax related to Assets and Liabilities arising from a Single Transaction – Amendments to IAS 12 The amendments to IAS 12 Income Tax The amendments had no impact on the Company’s consolidated financial statements. International Tax Reform—Pillar Two Model Rules – Amendments to IAS 12 The amendments to IAS 12 have been introduced in response to the Organisation for Economic Co-operation • A mandatory temporary exception to the recognition and disclosure of deferred taxes arising from the jurisdictional implementation of the Pillar Two model rules; and • Disclosure requirements for affected entities to help users of the financial statements better understand an entity’s exposure to Pillar Two income taxes arising from that legislation, particularly before its effective date. The mandatory temporary exception – the use of which is required to be disclosed – applies immediately. The remaining disclosure requirements apply for annual reporting periods beginning on or after 1 January 2023, but not for any interim periods ending on or before December 31, 2023. Management applied th e mand ii) Basis of consolidation The consolidated financial statements include the accounts of América Móvil, S.A.B. de C.V. and those subsidiaries over which the Company exercises control. The consolidated financial statements for the subsidiaries were prepared for the same period as the Company´s and applying consistent accounting policies. All of the subsidiary companies operate in the telecommunications sector or related. Subsidiaries are entities over which the Company has control. Control is achieved when the Company has power over the investee, when it is exposed to, or has rights to, variable returns from its involvement with the investee, and has the ability to use its power over the investee to affect the amount of the investor’s returns. Subsidiaries are consolidated on a line-by-line Changes in the Company’s ownership interests in a subsidiary that do not result in the Company losing control over the subsidiary are accounted for as equity transactions. The carrying amounts of the equity attributable to owners of the parent and non-controlling non-controlling Subsidiaries are deconsolidated from the date which control ceases. When the Company ceases to have control over a subsidiary, it derecognizes the assets (including any goodwill) and liabilities of the subsidiary at their carrying amounts, derecognizes the carrying amount of non-controlling All intra-Company balances and transactions, and any unrealized gains and losses arising from intra-Company transactions, are eliminated in preparing the consolidated financial statements. Non-controlling Non-controlling Associates: An associate is an entity over which the Company has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but does not have control or joint control over those decisions. The Company’s investment in associates includes goodwill identified on acquisition, net of any accumulated impairment losses. The investments in associated companies in which the Company exercises significant influence are accounted for using the equity method, whereby Company recognizes its share in the net profit (losses) and equity of the associate. Joint venture: A joint venture is an arrangement in which the Company has joint control, whereby the Company has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities. Interests in the joint venture are accounted for using the equity method. Pursuant to such method, the joint venture is initially recognized at cost, which includes transaction costs. Subsequent to initial recognition, the consolidated financial statements include the Company’s share of the profit or loss and OCI of equity-accounted investees, until the date on which significant influence or joint control ceases. The results of operations of the subsidiaries and associates are included in the Company’s consolidated financial statements beginning as of the month following their acquisition and its share of other comprehensive income after acquisition is recognized directly in other comprehensive income. The Company assesses at each reporting date whether there is objective evidence that investment in associates and joint venture is impaired. If so, the Company calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value. The equity interest in the most significant subsidiaries is as follows: Country Equity 2022 2023 Subsidiaries: América Móvil B.V. a) Netherlands 100.0 % 100.0 % Compañía Dominicana de Teléfonos, S.A.

The financial statements of foreign subsidiaries have been prepared under or converted to IFRS in the respective local currency (which is their functional currency) and then translated into the Company´s reporting currency as follows: • all monetary assets and liabilities were translated at the closing exchange rate of the period; • all non-monetary • equity accounts are translated at the exchange rate at the time the capital contributions were made and the profits were generated; • revenues, costs and expenses are translated at the average exchange rate of the period, except for the operations of the subsidiaries in Argentina, whose economy is considered hyperinflationary since 2018; • the consolidated statements of cash flows presented using the indirect method were translated using the weighted-average exchange rate for the applicable period (except for Argentina), and the resulting difference is shown in the consolidated statements of cash flows under the heading “Adjustment to cash flows due to exchange rate fluctuations, net”. The difference resulting from the translation process is recognized in equity in the caption “Effect of translation of foreign entities”. At December 31, 2022 and 2023, the cumulative translation adjustment was Ps. (128,299,347) and Ps. (164,975,378), respectively. The basis of translation for the operations of the subsidiaries in Argentina are described below: In recent years, the Argentina economy has shown high rates of inflation. Although inflation data has not been consistent in recent years and several indexes have coexisted, inflation in Argentina indicates that the three-year cumulative inflation rate exceeded 100% in 2018, which is one of the quantitative references established by IAS 29. As a result, Argentina was considered a hyperinflationary economy in 2018 and the Company applies hyperinflation accounting to its subsidiary whose functional currency is the Argentine peso for financial information for periods ending on or after July 1, 2018, however the calculation of the cumulative impact was measured as of January 1, 2018. In order to restate for hyperinflation its financial statements, the subsidiary used the series of indices defined by resolution JG No. 539/18 issued by the “Federación Argentina de Consejos Profesionales de Ciencias Económicas” (“FACPCE”), based on the National Consumer Price Index (IPC) published by the Instituto Nacional de Estadística y Censos (INDEC) of the Argentine Republic and the Wholesale Internal Price Index (IPIM) published by FACPCE. The cumulative index at December 31, 2023 is 3,576.400, while on an annual inflation for 2023 is 211.41%. The main implications are as follows: • Adjustment of the historical cost of non-monetary • The gain on the net monetary position caused by the impact of inflation in the year is included in the consolidated statements of comprehensive income as part of the caption “ Valuation of derivatives, interest cost from labor obligations and other financial items, net” • All items in the financial statements of the Argentine company are translated at the closing exchange rate, which at December 31, 2022 and 2023 were 0.1096 and 0.0209, respectively, per Argentine peso per Mexican peso.
Revenue recognition	b) Revenue recognition The Company revenues are derived principally from providing the following telecommunications services and products: wireless voice, wireless data and value-added services, fixed voice, fixed data, broadband and IT services, Pay TV and over-the-top The Company provides fixed and mobile services. These services are offered independently in contracts with customers or together with the sale of handsets (mobile) under the postpaid model. In accordance with IFRS 15 “ Revenues from contracts with customers ” The Company with respect to the provided services, it has market observable information, to determine the standalone selling price of the services. On the other hand, in the case of the sale of bundled mobile phones sold (including service and handset) by the Company, the allocation of the sales is done based on their relative standalone selling price of each individual component related to the total bundled price. The services provided by the Company are satisfied over the time of the contract period, given that the customer simultaneously receives and consumes the benefits provided by the Company. Such service bundles, voice and data, accomplish the criteria mentioned in IFRS 15 of being substantially similar and of having the same transfer pattern which is why the Company concluded that the revenue from these different services offered to its customers are considered as a single performance obligation with revenue being recognized over time, except for sales of equipment. Under IFRS 15, for those contracts with customers in which generally the sale of equipment and other electronic equipment is a single performance obligation, the Company recognizes the revenue at the moment when it transfers control to the customer which generally occurs when such goods are delivered. The commissions are considered incremental contract acquisition costs that are capitalized and are amortized over the expected period of benefit, during the average duration of customer contracts. Some subsidiaries have loyalty programs where the Company awards credits customer credit awards referred as “points”. The customer can redeem accrued “points” for awards such as devices, accessories or airtime. The Company provides all awards. The consideration allocated to the award credits is identified as a separate performance obligation; the corresponding liability of the award credits is measured at its fair value. The consideration allocated to award credits amount is recognized as a contract liability until the points are redeemed. Revenue is recognized upon redemption of products by the customer.
Cost of sales	c) Cost of sales The cost of mobile equipment and computers is recognized at the time the client and distributor receive the device which is when the control is transferred to the customer.
Cost of services	d) Cost of services The cost of services represents the costs incurred to properly deliver the services to the customers, it includes the network operating costs and licenses related costs and is accounted at the moment in which such services are provided.
Commissions to distributors	e) Commissions to distributors The Company pays commissions to its network of distributors primarily to acquire and retain customers for the Company. Such commissions are recognized in “commercial, administrative and general expenses”
Cash and cash equivalents	f) Cash and cash equivalents Cash and cash equivalents represent bank deposits and liquid investments with maturities of less than three months. These amounts are stated at cost plus accrued interest, which is similar to their market value. The Company also maintains restricted cash held as collateral to meet certain contractual obligations. As restricted cash the Company includes the judicial deposits that are presented as part of “Other assets, net” within non-current
Equity investments at fair value through OCI and other short/long-term investments	g) Equity investments at fair value through OCI and other short/long-term investments Equity investments at fair value through OCI and other short-term investments are primarily composed of equity investments and other short-term financial investments. Amounts are initially recorded at their estimated fair value. Fair value adjustments for equity investments are recorded through other comprehensive income, and other short-term investment.
Inventories	h) Inventories Inventories are initially recognized at historical cost and are valued using the average cost method without exceeding their net realizable value. The estimate of the realizable value of inventories on-hand
Business combinations and goodwill	i) Business combinations and goodwill Business combinations are accounted for using the acquisition method, which in accordance with IFRS 3, “ Business acquisitions (i) Identify the acquirer; (ii) Determine the acquisition date; (iii) Value the acquired identifiable assets and assumed liabilities; and (iv) Recognize the goodwill or a bargain purchase gain. For acquired subsidiaries, goodwill represents the difference between the purchase price and the fair value of the net assets acquired at the acquisition date. The investment in acquired associates includes goodwill identified on acquisition, net of any impairment loss. Goodwill is reviewed annually to determine its recoverability or more often if circumstances indicate that the carrying value of the goodwill might not be fully recoverable. The possible loss of value in goodwill is determined by analyzing the recovery value of the cash generating unit (or the group thereof) to which the goodwill is associated at the time it was originated. If this recoverable amount is lower than the carrying value, an impairment loss is charged to the results of operations. The recoverable amount is determined based on the higher of fair value less cost of disposal or value in use. For the years ended December 31, 2021, 2022 and 2023, no impairment losses were recognized for goodwill.
Property, plant and equipment	j) Property, plant and equipment i) Property, plant and equipment are recorded at acquisition cost, net of accumulated depreciation; except for the passive infrastructure of telecommunications towers, which are recognized under the revaluation model. Depreciation is computed on the cost of assets using the straight-line method, based on the estimated useful lives of the related assets, beginning the month after they become available for use. Borrowing costs that are incurred for general financing for construction in progress for a substantial period of time are capitalized as part of the cost of the asset. During the years ended December 31, 2021, 2022 and 2023, borrowing costs that were capitalized amounted to Ps. 1,527,259, Ps. 1,514,654 and Ps. 1,442,077, respectively. In addition to the purchase price and costs directly attributable to preparing an asset in terms of its physical location and condition for operating as intended by management, when required, the cost also includes the estimated costs of dismantling and removal of the asset and for restoration of the site where it is located. See Note 16c. The passive infrastructure of telecommunications towers is recorded at revalued value, which is its fair value at the time of revaluation less accumulated depreciation; if there is any loss or impairment, it must also be considered within its value. The revaluations will be calculated with sufficient regularity to ensure that the book value, every time, does not differ significantly from that which could be determined using the fair value at the end of the reporting period. The increase resulting from a revaluation is recorded in other comprehensive income (OCI) and is accumulated in equity as a revaluation surplus. To the extent that there is a decrease in revaluation, it will be recognized in profit or loss, except to the extent that it compensates for an existing surplus on the same asset. An annual transfer of the asset revaluation surplus and accumulated earnings is made to the extent that the asset is used, therefore, the surplus is equal to the difference between the depreciation calculated on the revalued value and the one calculated according to its original cost. These transfers do not record in the results for the period. A total transfer of the surplus may be made when the entity disposes of the asset. ii) The net book value of property, plant and equipment is removed from the consolidated statements of financial position at the time the asset is sold or when no future economic benefits are expected from its use or sale. Any gains or losses on the sale of property, plant and equipment represent the difference between net proceeds of the sale and the net book value of the item at the time of sale, that are recognized as either other operating income or other operating expenses upon sale. iii) The Company periodically assesses the residual values, useful lives and depreciation methods associated with its property, plant and equipment. If necessary, the effects of any changes in accounting estimates is recognized prospectively, at the closing of each period, in accordance with IAS 8, “ Accounting Policies, Changes in Accounting Estimates and Errors For property, plant and equipment made up of several components with different useful lives, the major individual components are depreciated over their individual useful lives. Maintenance costs and repairs are expensed as incurred. Annual depreciation rates are as follows: Network infrastructure 5%-33% Buildings and leasehold improvement 2%-33% Other assets 10%-50% iv) The carrying value of property, plant and equipment is reviewed annually if there are indicators of impairment in such assets. If an asset’s recovery value is less than the asset’s net carrying value, the difference is recognized as an impairment loss. During the years ended December 31, 2021, 2022 and 2023, no impairment losses were recognized. v) Spare parts for network operation are recognized at cost. The valuation of inventory for network considered obsolete, defective or slow-moving, is reduced to their estimated net realizable value. The estimate of the recovery value of inventories is based on their age and turnover.
Intangibles	k) Intangibles i) Licenses Licenses to operate wireless telecommunications networks granted by the governments of the countries in which the Company operates are recorded at acquisition cost or at fair value at their acquisition date, net of accumulated amortization. Certain licenses require payments to the governments, such payments are recognized in the cost of service and equipment. The licenses that in accordance with government requirements are categorized as automatically renewable, for a nominal cost and with substantially consistent terms, are considered by the Company as intangible assets with an indefinite useful life. Accordingly, they are not amortized. Licenses are amortized when the Company does not have a basis to conclude that they are indefinite lived. Other licenses are amortized using the straight-line method over a period ranging from 3 to 30 years, which represents the usage period of the assets. The Company has conducted an internal analysis on the applicability of the International Financial Reporting Interpretation Committee (“IFRIC”) No. 12 (Service Concession Agreements) and has concluded that its concessions are outside the scope of IFRIC 12. To determine the applicability of IFRIC 12, the Company analyzes each concession or group of similar concessions in a given jurisdiction. As a threshold matter, the Company identifies those government concessions that provide for the development, financing, operation or maintenance of infrastructure used to render a public service, and that set out performance standards, mechanisms for adjusting prices and arrangements for arbitrating disputes. With respect to those services, the Company evaluates whether the grantor controls or regulates (i) what services the operator must provide, (ii) to whom it must provide them and (iii) the applicable price (the “Services Criterion”). In evaluating whether the applicable government, as grantor, controls the price at which the Company provides its services, the Company looks at the terms of the concession agreement according to all applicable regulations. If the Company determines that the concession under analysis meets the Services Criterion, then the Company evaluates whether the grantor would hold a significant residual interest in the concession’s infrastructure at the end of the term of the arrangement. ii) Trademarks Trademarks acquired are measured on initial recognition at cost. The cost of trademarks acquired in a business combination is their fair value at the date of acquisition. The useful lives of trademarks are assessed as either definite or indefinite. Trademarks with finite useful lives are amortized using the straight-line method over a period ranging from 1 to 10 years. The assessment of indefinite life is reviewed annually to determine whether the indefinite life continues to be supportable, if not, the change in useful life from indefinite to definite is made on a prospective basis. iii) Irrevocable rights of use Irrevocable rights of use are recognized according to the amount paid for the right and are amortized over the period in which they are granted. The carrying values of the Company’s licenses and trademarks are reviewed annually and whenever there are indicators of impairment in the value of such assets. When an asset’s recoverable amount, which is the higher of the asset’s fair value, less disposal costs and its value in use (the present value of future cash flows), is less than the asset’s carrying value, the difference is recognized as an impairment loss. iv) Customer relationships The value of customer relations is determined and valued at the time that a new subsidiary is acquired, as determined by the Company with the assistance of independent appraisers and is amortized over a 5-year During the years ended December 31, 2021, 2022 and 2023, no significant impairment losses were recognized for licenses, trademarks, irrevocable rights of use or customer relationships.
Impairment in the value of long-lived assets	l) Impairment in the value of long-lived assets The Company assesses the existence of indicators of impairment in the carrying value of long-lived assets, goodwill and intangible assets according to IAS 36 “ Impairment of assets pre-tax In the estimation of impairments, the Company uses the strategic plans established for the separate cash-generating units to which the assets are assigned. Such strategic plans generally cover a period from 3 to 5 years. For longer periods, beginning in the fifth year, projections are based on such strategic plans while applying a constant or declining expected perpetual growth rate. Key assumptions used in value in use calculations The forecasts are made in real terms (net of inflation) and in the functional currency of the subsidiary as of December 31, 2023. Financial forecasts, premises and assumptions are similar to what any other market participant in similar conditions would consider. Local synergies, that any other market participant would not have taken into consideration to prepare similar forecasted financial information, have not been included. The assumptions used to develop the financial forecasts were validated for each of the cash generating units (“CGUs”), typically identified by country and by service (in the case of Mexico fixed and mobile) taking into consideration the following: • Current subscribers and expected growth; • Type of subscribers (prepaid, postpaid, fixed line, multiple services); • Market environment and penetration expectations; • New products and services; • Economic environment of each country; • Expenses for maintaining the current assets; • Investments in technology for expanding the current assets; and • Market consolidation and synergies. The foregoing forecasts could differ from the results obtained through time; however, the Company prepares its estimates based on the current situation of each of the CGUs. The recoverable amounts are based on value in use. The value in use is determined based on the method of discounted cash flows. The key assumptions used in projecting cash flows are: • Margin on EBITDA is determined by dividing EBITDA (operating income plus depreciation and amortization) by total revenues. • Margin on CAPEX is determined by dividing capital expenditures (“CAPEX”) by total revenues. • Post-tax As discount rate, the Company uses the WACC which was determined for each of the cash generating units and is described in the following paragraphs. The estimated discount rates to perform the IAS 36 “ Impairment of assets The discount rates represent the current market assessment of the risks specific to each CGU, taking into consideration the time value of money and individual risks of the underlying assets that have not been incorporated in the cash flow estimates. The discount rate calculation is based on the specific circumstances of the Company and its operating segments. The WACC takes into account both debt and equity costs. The cost of equity is derived from the expected return on investment for each GCU. The cost of debt is based on the interest-bearing borrowings the Company is obliged to service. Segment-specific risk is incorporated by applying individual beta factors. The beta factors are evaluated annually based on publicly available market data. Market participant assumptions are important because, not only do they include industry data for growth rates, but also management assesses how the CGU’s position, relative to its competitors, might change over the forecasted period. The most significant forward-looking estimates used for the 2022 and 2023 impairment evaluations are shown below: Average margin on Average margin on Average pre-tax 2022: Europe (7 countries) 32.70% - 47.31% 7.7% - 21.1% 5.47% - 24.11% Brazil (fixed line, wireless and TV) 41.90% 19.62% 9.30% Puerto Rico 26.98% 8.91% 6.14% Dominican Republic 53.93% 13.82% 11.13% Mexico (fixed line and wireless) 36.19% 18.61% 8.60% Ecuador 47.14% 18.42% 20.13% Peru 36.53% 21.05% 10.39% El Salvador 45.18% 17.59% 22.37% Colombia 42.25% 27.41% 13.70% Other countries 32.92% - 49.54% 9.63% - 25.97% 9.16% - 29.94% 2023: Europe (7 countries) 26.81% - 43.90% 4.46% - 16.89% 6.08% - 29.15% Brazil (fixed line, wireless and TV) 43.07% 14.37% 10.45% Puerto Rico 23.92% 10.46% 6.31% Dominican Republic 52.34% 13.78% 11.95% Mexico (fixed line and wireless) 36.10% 10.66% 9.37% Ecuador 50.81% 18.49% 21.77% Peru 41.80% 7.11% 9.13% El Salvador 46.27% 9.26% 20.15% Colombia 43.39% 20.78% 10.15% Other countries 28.06% - 51.46% 11.68% - 27.15% 10.29% - 22.79% Sensitivity to changes in assumptions: The implications of the key assumptions for the recoverable amount are discussed below: Margin on CAPEX- The Company performed a sensitivity analysis by increasing its CAPEX by 5% and maintaining all other assumptions the same. The sensitivity analysis would require the Company to adjust the amount of its long-lived assets in one of its CGUs with potential impairment of approximately Ps. 1,208,795. WACC- Additionally, should the Company increase by 50 base points in WACC per CGU and maintain all other assumptions the same. The sensitivity analysis would require the Company to adjust the amount of its long-lived assets in one of its CGUs with potential impairment of approximately Ps. 1,235,848.
Right-of-use assets	m Right-of-use The Company applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value right-of-use i) Right-of-use The Company recognizes right-of-use Right-of-use right-of-use before the commencement date less any lease incentives received. Right-of-use Assets Useful life Towers and sites 2 to 24 years Property 2 to 24 years Other equipment 2 to 20 years The right-of-use ii) Lease liabilities. At the commencement date of the lease, the Company recognizes the lease liabilities measured at the present value of the lease payments to be made over the lease term. Lease payments include fixed payments (including in-substance In calculating the present value of the lease payments, the Company uses an incremental borrowing rate at the lease commencement date, if the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of the lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the in-substance iii) Short-term leases and leases of low value assets. The Company applies the short-term lease recognition exemption for its leases of machinery and equipment (i.e., those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). It also applies the recognition exemption lease of low-value low-value
Financial assets and liabilities	n) Financial assets and liabilities Financial assets Initial recognition and measurement Financial assets are classified, at initial recognition, as subsequently measured at amortized cost, fair value through other comprehensive income (OCI), and fair value through profit or loss. The classification of financial assets at initial recognition depends on the financial asset’s contractual cash flow characteristics and the Company’s business model for managing them, with the exception of trade receivables that do not contain a significant financing component or for which the Company has applied the practical expedient, the Company initially measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs. Subsequent measurement For purposes of subsequent measurement, financial assets are classified in four categories: • Financial assets at amortized cost (debt instruments); • Financial assets at fair value through OCI with recycling of cumulative gains and losses (debt instruments); • Financial assets designated at fair value through OCI with no recycling of cumulative gains and losses upon derecognition (equity instruments); and • Financial assets at fair value through profit or loss. Financial assets at amortized cost (debt instruments) The Company measures financial assets at amortized cost if both of the following conditions are met: • The financial asset is held within a business model with the objective to hold financial assets in order to collect contractual cash flows; and • The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Financial assets at amortized cost are subsequently measured using the effective interest (EIR) method and are subject to impairment. Gains and losses are recognized in profit or loss when the asset is derecognized, modified or impaired. The Company’s financial assets at amortized cost includes cash equivalents and receivables. Financial assets at fair value through OCI with recycling of cumulative gains and losses (debt instruments) The Company measures debt instruments at fair value through OCI if both of the following conditions are met: • The financial asset is held within a business model with the objective of both holding to collect contractual cash flows and selling; and • The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. For debt instruments at fair value through OCI, interest income, foreign exchange revaluation and impairment losses or reversals are recognized in the statements of profit or loss and computed in the same manner as for financial assets measured at amortized cost. The remaining fair value changes are recognized in OCI. Upon derecognition, the cumulative fair value change recognized in OCI is recycled to profit or loss. Financial assets designated at fair value through OCI with no recycling of cumulative gains and losses upon derecognition (equity instruments) Upon initial recognition, the Company can elect to classify irrevocably its equity investments as equity instruments designated at fair value through OCI when they meet the definition of equity under IAS 32 Financial Instruments: Presentation Gains and losses on these financial assets are never recycled to profit or loss. Dividends are recognized as other income in the consolidated statements of comprehensive income when the right of payment has been established, except when the Company benefits from such proceeds as a recovery of part of the cost of the financial asset, in which case, such gains are recorded in OCI. Equity instruments designated at fair value through OCI are not subject to impairment assessment. Financial assets at fair value through profit or loss Financial assets at fair value through profit or loss include financial assets held for trading, financial assets designated upon initial recognition at fair value through profit or loss, or financial assets mandatorily required to be measured at fair value. Financial assets are classified as held for trading if they are acquired for the purpose of selling or repurchasing in the near term. Derivatives, including separated embedded derivatives, are also classified as held for trading unless they are designated as effective hedging instruments. Financial assets with cash flows that are not solely payments of principal and interest are classified and measured at fair value through profit or loss, irrespective of the business model. Notwithstanding the criteria for debt instruments to be classified at amortized cost or at fair value through OCI, as described above, debt instruments may be designated at fair value through profit or loss on initial recognition if doing so eliminates, or significantly reduces, an accounting mismatch. Financial assets at fair value through profit or loss are carried in the statements of financial position at fair value with net changes in fair value recognized in the consolidated statements of comprehensive income within “Valuation of derivatives, interest cost from labor obligations and other financial items”. Derecognition of financial assets A financial asset is primarily derecognized when: • The rights to receive cash flows from the asset have expired, or • The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ‘pass-through’ arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset. When the Company has transferred its rights to receive cash flows from an asset or has entered into a passthrough arrangement, it evaluates if, and to what extent, it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of its continued involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained. Impairment of financial assets The Company recognizes an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Company expects to receive, discounted at an approximation of the original effective interest rate. The expected cash flows will include cash flows from the sale of collateral held or other credit enhancements that are integral to the contractual terms. ECLs are recognized in two stages. For credit exposures for which there has not been a significant increase in credit risk since initial recognition, ECLs are provided for credit losses that result from default events that are possible within the next 12-months 12-month For some trade receivables and contract assets based on available information loss rate approach Financial liabilities Initial recognition Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate. All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs. The Company’s financial liabilities include trade and other payables, loans and borrowings including bank overdrafts, and derivative financial instruments. Subsequent measurement The measurement of financial liabilities depends on their classification, as described below: Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss. Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Company that are not designated as hedging instruments in hedge relationships as defined by IFRS 9. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments. Gains or losses on liabilities held for trading are recognized in the statements of profit or loss. Financial liabilities designated upon initial recognition at fair value through profit or loss are designated at the initial date of recognition, and only if the criteria in IFRS 9 are satisfied. The Company has not designated any financial liability as at fair value through profit or loss. Loans and borrowings After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the statements of profit or loss. Derecognition of financial liabilities A financial liability is derecognized when the obligation under the liability is discharged, cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the consolidated statements of comprehensive income. Offsetting of financial instruments Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statements of financial position if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.
Transactions in foreign currency	o) Transactions in foreign currency Transactions in foreign currency are initially recorded at the prevailing exchange rate at the time of the related transactions. Foreign currency denominated assets and liabilities are subsequently translated at the prevailing exchange rate at the financial statements reporting date. Exchange differences determined from the transaction date to the time foreign currency denominated assets and liabilities are settled or translated at the financial statements reporting date are charged or credited to the results of operations. In determining the spot exchange rate to use on initial recognition of the related asset, expense or income (or part of it) on the derecognition of a non-monetary non-monetary non-monetary non-monetary The exchange rates used for the translation of foreign currencies against the Mexican peso are as follows: Average exchange rate Closing exchange rate Country or Zone Currency 2021 2022 2023 2022 2023 Argentina (1) Argentine Peso (AR$) 0.2137 0.1586 0.0680 0.1096 0.0209 Brazil Real (R$) 3.7625 3.9045 3.5545 3.7209 3.4895 Colombia Colombian Peso (COP$) 0.0054 0.0048 0.0041 0.0040 0.0044 Guatemala Quetzal 2.6212 2.5981 2.2675 2.4725 2.1584 U.S.A.

In December 2023, a new Argentine administration took office and called for new economic framework calling for liberalization of economic policy. This caused a major devaluation of the country’s currency, with the Argentine peso losing nearly 60% of its value vis-á-vis In addition, as of December 31, 2023, the Argentinean peso suffered a devaluation of its currency of 80.9% year-to-date Financial reporting in hyperinflationary economies Financial statements of Argentina subsidiaries are restated before translation to the reporting currency of the Company and before consolidation in order to reflect the same value of money for all items. Items recognized in the statements of financial position which are not measured at the applicable year-end non-monetary net-position As of April 29, 2 the exchange rate between the U.S. dollar and the Mexican peso was Ps. 17.155200. The depreciation of the Mexican peso against the US dollar represents 1.55% with respect to the year-end value.
Accounts payable, accrued liabilities and provisions	p) Accounts payable, accrued liabilities and provisions Liabilities are recognized whenever (i) the Company has current obligations (legal or assumed) resulting from a past event, (ii) when it is probable the obligation will give rise to a future cash disbursement for its settlement, and (iii) the amount of the obligation can be reasonably estimated. When the effect of the time value of money is significant, the amount of the liability is determined as the present value of the expected disbursements to settle the obligation. The discount rate is determined on a pre-tax Contingent liabilities are recognized only when it is probable, they will give rise to a future cash disbursement for their settlement.
Employee benefits	q) Employee benefits The Company has defined benefit pension plans for its subsidiaries Puerto Rico Telephone Company, Telmex, Claro S.A., and Telekom Austria. Claro S.A. also has medical plans and defined contribution plans and Telekom Austria provides retirement benefits to its employees under a defined contribution plan. The Company recognizes the costs of these plans based upon independent actuarial computations and are determined using the projected unit credit method. The latest actuarial computations were prepared as of December 31, 2023. Mexico Mexican subsidiaries have the obligation to pay seniority premiums to personnel based on the Mexican Federal Labor Law which also establishes the obligation to make certain payments to personnel who cease to provide services under certain circumstances. Pensions (for Telmex) and seniority premiums are determined based on the salary of employees in their final year of service, the number of years worked at and their age at the moment of retirement. The costs of pensions, seniority premiums and severance benefits, are recognized based on calculations by independent actuaries using the projected unit credit method using financial hypotheses, net of inflation. Telmex has established an irrevocable trust fund and makes annual contributions to that fund. Puerto Rico In Puerto Rico, the Company has noncontributing pension plans for full-time employees, which are tax qualified as they meet Employee Retirement Income Security Act of 1974 requirements. The pension benefit is composed of two elements: (i) An employee receives an annuity at retirement if they meet the rule of 85 (age at retirement plus accumulated years of service). The annuity is calculated by applying a percentage times year of services to the last three years of salary. (ii) The second element is a lump-sum Brazil Claro S.A. provides a defined benefit plan and post-retirement medical assistance plan, and a defined contribution plan, through a pension fund that supplements the government retirement benefit for certain employees. Under the defined benefit plan, the Company makes monthly contributions to the pension fund equal to 17.5% of the employee’s aggregate salary. In addition, the Company contributes a percentage of the aggregate salary base for funding the post-retirement medical assistance plan for the employees who remain in the defined benefit plan. Each employee makes contributions to the pension fund based on age and salary. All newly hired employees automatically adhere to the defined contribution plan and no further admittance to the defined benefit plan is allowed. For the defined contribution plan. See Note 18. Austria Telekom Austria provides retirement benefits to its employees under defined contribution and defined benefit plans. The Company pays contributions to publicly or privately administered pension or severance insurance plans on mandatory or contractual basis. Once the contributions have been paid, the Company has no further payment obligations. The regular contributions are recognized as employee expenses in the year in which they are due. All other employee benefit obligations provided in Austria are unfunded defined benefit plans for which the Company records provisions which are calculated using the projected unit credit method. The future benefit obligations are measured using actuarial methods on the basis of an appropriate assessment of the discount rate, rate of employee turnover, rate of compensation increase and rate of increase in pensions. For severance and pensions, the subsidiary recognizes actuarial gains and losses in other comprehensive income. The re-measurement Other subsidiaries For the rest of the Company’s subsidiaries, there are no defined benefit plans or compulsory defined contribution structures. However, certain subsidiaries make contributions to national pension, social security and severance plans in accordance with the percentages and rates established by the applicable social security and labor laws of each country. Such contributions are made to the entities designated by the countries legislation and are recorded as direct labor expenses in the consolidated statements of comprehensive income as they are incurred. Remeasurements of defined benefit plans, comprising of actuarial gains and losses, the effect of the asset ceiling, excluding net interest and the return on plan assets (excluding net interest), are recognized immediately in the consolidated statements of financial position with a corresponding debit or credit to “Remeasurement of defined benefit plan” through OCI in the period in which they occur. Re-measurements Past service costs are recognized in profit or loss on the earlier of: (i) The date of the plan amendment or curtailment; and (ii) The date that the Company recognizes restructuring-related costs. Net interest on liability for defined benefits is calculated by applying the discount rate to the net defined benefit liability or asset and it is recognized in the “valuation of derivatives, interest cost from labor obligations and other financial items” in the consolidated statements of comprehensive income. The Company recognizes the changes in the net defined benefit obligation under “Cost of sales and services” and “Commercial, administrative and general expenses” in the consolidated statements of comprehensive income. Paid absences The Company recognizes a provision for the cost of paid absences, such as vacation time, based on the accrual method.
Employee profit sharing ("EPS")	r) Employee profit sharing (“EPS”) EPS is paid by certain subsidiaries of the Company to its eligible employees. The Company has employee profit sharing in Mexico, Ecuador and Peru. In Mexico, employee profit sharing is computed at the rate of 10% on the individual subsidiaries taxable base adjusted for employee profit sharing purposes as provided by law. Employee profit sharing is presented as an operating expense in the consolidated statements of comprehensive income. The amendment to the Federal Labor Law in Mexico dated April 23, 2021 established a limit on the amount to be paid for profit sharing to employees, which indicates that the amount of EPS assigned to each employee may not exceed the equivalent of three months of the employee’s current salary, or the average EPS received by the employee in the previous three years, whichever is greater. If the EPS determined is less than or equal to this limit, the EPS will be determined by applying 10% of the individual company taxable income. If the EPS determined exceeds this limit, the limit would apply and this should be considered the EPS for the period.
Taxes	s) Taxes Income taxes Current income tax payable is presented as a short-term liability, net of prepayments made during the year. Deferred income tax is determined using the liability method based on the temporary differences between the tax values of the assets and liabilities and their book values at the consolidated financial statements reporting date. Deferred tax assets and liabilities are measured using the tax rates that are expected to be in effect in the period when the asset will materialize or the liability will be settled, based on the enacted tax rates (and tax legislation) that have been enacted or substantially enacted at the financial statements reporting date. The value of deferred tax assets is reviewed by the Company at each financial statement reporting date and is reduced to the extent that it is more likely that the Company will not have sufficient future tax profits to allow for the realization of all or a part of its deferred tax assets. Unrecognized deferred tax assets are revalued at each financial statement reporting date and are recognized when it is more likely that there will be sufficient future tax profits to allow for the realization of these assets. Deferred taxes relating to items recognized in Other Comprehensive Income are recognized together with the concept that generated such deferred taxes. Deferred taxes consequence on unremitted earnings from subsidiaries and associates are considered as temporary differences, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future. Taxes withheld on remitted foreign earnings are creditable against Mexican taxes, thus to the extent that a remittance is to be made, the deferred tax would be limited to the incremental difference between the Mexican tax rate and the rate of the remitting country. As of December 31, 2022 and 2023, the Company has not provided for any deferred taxes related to unremitted foreign earnings. The Company offsets tax assets and liabilities if it has a legally enforceable right to set off current tax assets and current tax liabilities and the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same tax authority. Sales tax Revenues, expenses and assets are recognized net of the amount of sales tax, except: • When the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case, the sales tax is recognized as part of the cost of acquisition of the asset or as part of the expense item, as applicable. • Receivables and payables that are stated with the amount of sales tax included. The net amount of sales tax recoverable from, or payable to, the tax authorities is included as part of the current receivables or payables in the consolidated statements of financial position unless they are due in more than a year in which case they are classified as non-current. Uncertainty over Income Tax Treatments The acceptability of a particular tax treatment under tax law may not be known until the tax authority or courts of justice reach a decision in the future. Consequently, a dispute or inspection of a specific tax treatment by the tax authority could affect the accounting of the asset or liability for current or deferred taxes by the Company. In accordance with IFRIC 23 Uncertainty over Income Tax Treatments To determine the approach that best predicts the resolution of the uncertainty, the Company may consider, for example: (a) How does the Company prepare their income tax return and support such tax treatments and how it sustains the tax treatments. (b) How does the Company expect that the tax authority carry-out The Company must disclose in the notes to the consolidated financial statements what is mentioned below: 1) The Company must determine whether the uncertain tax treatments will be evaluated separately or as a whole; 2) The Company will assume that the authority will examine the tax situation and will be aware of considering all information relevant to said treatment; 3) If it is concluded that it is unlikely that the authority will accept an uncertain fiscal position, the effect of the uncertainty will be reflected when determining its accounting fiscal position, estimating the effect based on the following methods: a) Most probable quantity – is the only quantity in a range of possible outcomes that can be predicted by the resolution of the uncertainty; either, b) Expected value – is the value resulting from the sum of the different amounts weighted by their probability of occurrence, in a range of possible results. The expected value is the one that can best predict the resolution of the uncertainty, if there is a range of possible outcomes. 4) If the uncertain tax treatment affects the tax base for tax (caused) and deferred tax, the Company must make consistent judgments and estimates in the determination of both taxes; and 5) The Company must reassess a judgment or estimate of an uncertain tax treatment and its effects, if the facts and circumstances on which they were initially based change, or if new information arises that affects the judgment or estimate. ´ The effects should be recognized as a change in an accounting estimate based on the provision of IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors.
Advertising	t) Advertising Advertising expenses are recognized as incurred. For the years ended December 31, 2021, 2022 and 2023, advertising expenses were Ps. 11,118,723, Ps. 12,676,350 and Ps. 11,781,250 respectively, and are presented in the consolidated statements of comprehensive income in the caption “Commercial, administrative and general expenses”.
Earnings per share	u) Earnings per share Basic and diluted earnings per share are determined by dividing net profit of the year by the weighted-average number of shares outstanding during the year. In determining the weighted average number of outstanding shares, shares repurchased by the Company have been excluded.
Financial risks	v) Financial risks The main risks associated with the Company’s financial instruments are: (i) liquidity risk, (ii) market risk (foreign currency exchange risk and interest rate risk) and (iii) credit risk and counterparty risk. The Board of Directors approves the policies submitted by management to mitigate these risks. i) Liquidity risk Liquidity risk is the risk that the Company may not meet its financial obligations associated with financial instruments when they are due. The Company’s financial obligations and commitments are included in Notes 14 and 17. ii) Market risk The Company is exposed to certain market risks derived from changes in interest rates and fluctuations in exchange rates of foreign currencies. The Company’s debt is denominated in foreign currencies, mainly in US dollars and euros, other than its functional currency. In order to reduce the risks related to fluctuations in the exchange rate of foreign currency, the Company uses derivative financial instruments such as cross-currency swaps and forwards to adjust exposures resulting from foreign exchange currency. The Company does not use derivatives to hedge the exchange risk arising from having operations in different countries. Additionally, the Company occasionally uses interest rate swaps to adjust its exposure to the variability of the interest rates or to reduce their financing costs. The Company’s practices vary from time to time depending on judgments about the level of risk, expectations of change in the movements of interest rates and the costs of using derivatives. The Company may terminate or modify a derivative financial instrument at any time. See Note 7 for disclosure of the fair value of derivatives as of December 31, 2022 and 2023. iii) Credit risk Credit risk represents the loss that could be recognized in case the counterparties fail to comply with their contractual obligations. The financial instruments that potentially represent concentrations of credit risk are cash and short-term deposits, trade accounts receivable and financial instruments related to debt and derivatives. The Company’s policy is designed in order to limit its exposure to any one financial institution; therefore, the Company’s financial instruments are contracted with several different financial institutions located in different geographic regions. The credit risk in accounts receivable is diversified because the Company has a broad customer base that is geographically dispersed. The Company continuously evaluates the credit conditions of its customers and generally does not require collateral to guarantee collection of its accounts receivable. The Company monitors on a monthly basis its collection cycle to avoid deterioration of its results of operations. A portion of the Company’s cash surplus is invested in short- term deposits with financial institutions with high credit ratings. iv) Sensitivity analysis for market risks The Company uses sensitivity analysis to measure the potential losses based on a theoretical increase of 100 basis points in interest rates and a 5% fluctuation in exchange rates: Interest rate In the event that the Company’s agreed-upon interest rates at December 31, 2023 and 2022 increase/decrease by 100 basis points and a 5.68% and 6.33%, respectively, fluctuation in exchange rates between the Mexican Peso and US Dollar, the net interest expense would increase by Ps.8,046,987 and Ps. 1,828,215, respectively; and (decrease) by Ps. (4,941,344) and Ps. (11,128,215), respectively. Exchange rate fluctuations If the Company’s debt at December 31, 2023 and 2022 of Ps. 500,677,051 and Ps. 510,589,480, respectively, were to be impacted by a 5% increase/(decrease) in exchange rates, the debt would increase/(decrease) by Ps. 525,710,904 and Ps. 536,118,954, respectively; or Ps. (475,643,199) and Ps. (485,060,006), respectively.
Derivative financial instruments	w) Derivative financial instruments Derivative financial instruments are recognized in the consolidated statements of financial position at fair value. Valuations obtained by the Company are compared against those of the financial institutions with which the agreements are entered into, and it is the Company’s policy to compare such fair value to a valuation provided by an independent pricing provider in case of discrepancies. Changes in the fair value of derivatives that do not qualify as hedging instruments are recognized immediately in the line “Valuation of derivatives, interest cost from labor obligations and other financial items, net”. The Company is exposed to interest rate and foreign currency risks, which tries to mitigate through a controlled risk management program that includes the use of derivative financial instruments. The Company principally uses to attempt to offset the risk of exchange rate and interest rate fluctuations. Additionally, for the years ended December 31, 2021, 2022 and 2023 certain of the Company’s derivative financial instruments had been designated, and had qualified, as cash flow hedges. The effective portion of gains or losses on the cash flow derivatives is recognized in equity under the heading “Unrealized (loss) gain on equity investment at fair value”, and the ineffective portion is charged to results of operations of the period.
Current versus non-current classification	x) Current versus non-current The Company presents assets and liabilities in its consolidated statements of financial position based on current/non-current An asset is current when it is either: (i) Expected to be realized or intended to be sold or consumed in the normal operating cycle. (ii) Held primarily for the purpose of trading. (iii) Expected to be realized within twelve months after the reporting period. (iv) Cash and cash equivalents unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period. A liability is current when: • It is expected to be settled in the normal operating cycle. • It is held primarily for the purpose of trading. • It is due to be settled within twelve months after the reporting period. • There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period. The Company classifies all other assets and liabilities, including deferred income tax assets and liabilities, as non-current.
Presentation of consolidated statements of comprehensive income	y) Presentation of consolidated statements of comprehensive income The costs and expenses shown in the consolidated statements of comprehensive income are presented in combined manner (based on both their function and nature), which allows a better understanding of the components of the Company’s operating income. This classification allows a comparison to the telecommunications industry. The Company presents operating income in its consolidated statements of comprehensive income since it is a key indicator of the Company’s performance. Operating income represents operating revenues less operating costs and expenses.
Operating segments	z) Operating segments Segment information is presented based on information used by management in its decision-making processes. Segment information is presented based on the geographic areas in which the Company operates. The management of the Company is responsible for making decisions regarding the resources to be allocated to the Company’s different segments, as well as evaluating the performance of each segment. Intersegment revenues and costs, intercompany balances as well as investments in shares in consolidated entities are eliminated upon consolidation and reflected in the “eliminations” column in Note 23. None of the segment’s records revenue from transactions with a single external customer amounting to 10% or more of the revenues.
Convenience translation	Aa) Convenience translation The consolidated financial statements are stated in thousands of Mexican pesos (“Ps.”); however, solely for the convenience of the readers, the consolidated statement of financial position as of December 31, 2023 and the consolidated statement of comprehensive income and consolidated statement of cash flows for the year ended December 31, 2023 were converted into U.S. dollars at the exchange rate of Ps. 16.8935 per U.S. dollar, which was the exchange rate at that date. This arithmetic conversion should not be construed as representations that the amounts expressed in Mexican pesos may be converted into U.S. dollars at that or any other exchange rate.
Significant accounting judgments, estimates and assumptions	Ab) Significant accounting judgments, estimates and assumptions In preparing its consolidated financial statements, the Company makes estimates concerning a variety of matters. Some of these matters are highly uncertain, and its estimates involve judgments it makes based on the available information. In the discussion below, the Company has identified several of these matters for which its financial statements would be materially affected if either (1) the Company uses different estimates that it could have reasonably used or (2) in the future América Móvil changes its estimates in response to changes that are reasonably likely to occur. The following discussion addresses only those estimates that the Company considers most important based on the degree of uncertainty and the likelihood of a material impact had it used a different estimate. There are many other areas in which the Company uses estimates about uncertain matters, but the reasonably likely effect of changed or different estimates is not material to the financial presentation for those other areas. Estimated useful lives of property, plant and equipment The Company currently depreciates most of its network infrastructure based on an estimated useful life determined upon the expected particular conditions of operation and maintenance in each of the countries in which it operates. The estimates are based on AMX’s historical experience with similar assets, anticipated technological changes and other factors, taking into account the practices of other telecommunications companies. The Company reviews estimated useful lives each year to determine, for each particular class of assets, whether they should be changed. The Company may shorten/extend the estimated useful life of an asset class in response to technological changes, changes in the market or other developments. This results in increased/decreased depreciation expense. See Note 10. Revaluation of passive infrastructure of telecommunications towers The Company recognizes the passive infrastructure of the telecommunication towers at fair value, recognizing the changes in OCI. The discounted cash flow model was used. The Company hired a valuation specialist with industry experience to measure fair values as of December 31, 2023. Impairment of Long-Lived Assets The Company has large amounts of long-lived assets, including property, plant and equipment, intangible assets, and goodwill on its consolidated statements of financial position. The Company is required to test long-lived assets for impairment when circumstances indicate a potential impairment or, in some cases, at least on an annual basis. The impairment analysis for long-lived assets requires the Company to estimate the recoverable amount of the asset, which is the higher of its fair value (minus any disposal costs) and its value in use. To estimate the fair value of a long-lived asset, the Company typically takes into account recent market transactions or, if no such transactions can be identified, the Company uses a valuation model that requires making certain assumptions and estimates. Similarly, to estimate the value in use of long-lived assets, the Company typically makes various assumptions about the future prospects for the business to which the asset relates, considers market factors specific to that business and estimates future cash flows to be generated by that business. Based on this impairment analysis, including all assumptions and estimates related thereto, as well as guidance provided by IFRS relating to the impairment of long-lived assets different assumptions and estimates could materially impact the Company’s reported financial results. More conservative assumptions of the anticipated future benefits from these businesses could result in impairment charges, which would decrease net income and result in lower asset values on the consolidated statements of financial position. Conversely, less conservative assumptions could result in smaller or no impairment charges, higher net income and higher asset values. The key assumptions used to determine the recoverable amount for the Company’s CGUs, are further explained in Notes 23, 10 and 11. Deferred Income Taxes The Company is required to estimate its income taxes in each of the jurisdictions in which it operates. This process involves the jurisdiction-by-jurisdiction In assessing the future realization of deferred tax assets, the Company considers future taxable income, ongoing planning strategies and future results in its operations. In the event that the estimates of projected future taxable income are lowered, or changes in current tax regulations are enacted that would impose restrictions on the timing or extent of the ability to utilize the tax benefits of net operating loss carry-forwards in the future, an adjustment to the recorded amount of deferred tax assets would be made, with a related charge to income. See Note 13. Provisions Provisions are recorded when, at the end of the period, the Company has a present obligation as a result of past events, whose settlement requires an outflow of resources that is considered probable and can be measured reliably. This obligation may be legal or constructive, arising from, but not limited to, regulation, contracts, common practice or public commitments, which have created a valid expectation for third parties that the Company will assume certain responsibilities. The amount recorded is the best estimation performed by the Company’s management in respect of the disbursement that will be required to settle the obligations, considering all the information available at the date of the consolidated financial statements, including the opinion of external experts, such as legal advisors or consultants. Provisions are adjusted to account for changes in circumstances for ongoing matters and the establishment of additional provisions for new matters. If the Company is unable to reliably measure the obligation, no provision is recorded, and information is then presented in the notes to its consolidated financial statements. Because of the inherent uncertainties in these estimations, actual expenditures may be different from the originally estimated amount recognized. See Note 16. The Company is subject to various claims and contingencies related to tax, labor and legal proceedings as described in Note 17b). Labor Obligations The Company recognizes liabilities on its consolidated statements of financial position and expenses in its statements of comprehensive income to reflect its obligations related to its post-retirement seniority premiums, pension and retirement plans in the countries in which it operates and offer defined contribution and benefit pension plans. The amounts the Company recognizes are determined on an actuarial basis that involves estimations and accounts for post-retirement and termination benefits. The Company uses estimates in four specific areas that have a significant effect on these amounts: (i) the rate of return the Company assumes its pension plans will earn on its investments, (ii) the salaries increase rate that the Company assumes it will observe in future years, (iii) the discount rates that the Company uses to calculate the present value of its future obligations and (iv) the expected inflation rate. The assumptions applied are further disclosed in Note 18. These estimates are determined based on actuarial studies performed by independent experts using the projected unit-credit method.
Discontinued operations	Ac) Discontinued operations a) Joint Venture On October 6, 2022, LLA and the Company announced that they completed the transaction to combine their operations in Chile (VTR and Claro Chile, respectively) in order to create a 50:50 joint venture known as ClaroVTR. In accordance with IFRS 11, this transaction was classified as a joint venture, since both LLA and the Company exercise joint control over ClaroVTR, and all relevant decisions require the consent of both parties. Consequently, in accordance with IFRS 5, Claro Chile’s operations are classified as discontinued operations for all the years that are presented in the consolidated financial information and from that date they are recognized by applying the equity method. See Note 12b. The results of discontinued operations are as follows: For the years For the period Operating revenue: Service revenues Ps. 17,276,464 Ps. 10,500,087 Sales of equipment 4,508,925 2,626,823 21,785,389 13,126,910 Total costs and expenses 22,892,415 14,954,526 Operating loss (1,107,026 ) (1,827,616 ) Financial costs (533,899 ) (685,129 ) Loss before income taxes of discontinued operations (1,640,925 ) (2,512,745 ) Income taxes: (4,578,004 ) (1,805,500 ) Net profit (loss) of the period from discontinued operations Ps. 2,937,079 Ps. (707,245 ) The effect of the deconsolidation of Claro Chile, S.A. as of October 6, 2022, resulted in the recognition of a loss after tax from discontinued operations of Ps. 707,245, including a recycling income of accumulated foreign currency translation effect for an amount of Ps. 6,943,753. Therefore, Claro Chile is deconsolidated from the aforementioned date and no impairment loss was identified. b) Claro Panama Disposal On September 15, 2021, the Company announced that it had entered into an agreement with Cable & Wireless Panama, S.A., an affiliate of Liberty Latin America to sell its 100% interest in its subsidiary Claro Panama. The transaction excludes the telecommunications towers that are owned indirectly by the Company in Panama and the Claro trademarks. The agreed purchase price was US$200 million, adjusted for net debt (cash/debt free basis). The closing of the transaction would be subject to customary conditions for this type of transaction, including obtaining regulatory authorizations. On July 1, 2022, the Company announced that it had completed the sale to Liberty Latin America of its 100% interest in Claro Panama. The Company received an adjusted closing consideration of US$ 116.7 million in cash, resulting in a net gain of Ps. 3,405,014, including a recycling loss of accumulated foreign currency translation effect for an amount of Ps. 1,750,451. This gain has been recognized in profit after tax for the period from discontinued operations in the consolidated statement of comprehensive income. Therefore, Claro Panama is deconsolidated from the aforementioned date and no impairment loss was identified. In accordance with IFRS 5 Non-current The deconsolidated assets and liabilities of Claro Panama as of the date of disposal were the following: As of July 1, 2022 Current assets: Cash Ps. 24,202 Account receivable to subscribers, distributors and others Net 666,114 Inventories, net 169,851 Other assets, net 4,457 Total current assets 864,624 Non-current Property, plant and equipment 1,102,062 Intangibles, net 1,810,964 Account receivables to subscribers, distributors and others, Net 42,368 Other assets, net 12,291 Right-of-use 975,019 Total assets Ps. 4,807,328 Short term liability related to right-of-use Ps. 198,289 Accounts payable 576,522 Payable taxes 24,981 Related parties 1,159 Deferred income 126,904 Long term liability related to right-of-use Ps. 855,969 Deferred income 129,062 Total liabilities 1,912,886 Net assets directly related to the Group’s disposal Ps. 2,894,442 The results of discontinued operations for the year are shown below: For the year ended December 31, July 1 st  2021   2022  Operating revenue: Revenue services Ps.  2,667,497 Ps. 1,210,109 Sales of equipment 394,534 206,595 3,062,031 1,416,704 Total costs and expenses 3,378,614 1,403,311 Operating (loss) profit (316,583 ) 13,393 Financial costs (89,974 ) (39,538 ) Gain on sale of discontinued operations —  3,405,014 (Loss) profit before income taxes from discontinued operations (406,557 ) 3,378,869 Income taxes: 5,297 —  Net (loss) profit of the period of discontinued operations Ps.   (411,854 ) Ps. 3,378,869 c) TracFone Disposal On September 14, 2021, the Company, announced that it had entered into an agreement with Verizon Communications Inc. (“Verizon”) to sell its 100% interest in its subsidiary TracFone Wireless, Inc. (“TracFone”), the largest mobile virtual prepaid service operator in the United States, serving 21 million subscribers. On November 23, 2021, the Company announced that it had completed the sale of its 100% interest in TracFone to Verizon. AMX received a closing consideration of US$3,625.7 million in cash, which includes US$500.7 million related to TracFone’s closing cash and working capital, customary adjustment and other adjustments, and 57,596,544 shares of Verizon stock valued at approximately US$2,968 million. Verizon has asserted post-closing claims under the adjustments and other provisions of this agreement, which may result in payments by the Company. Following the transaction closing, Verizon shall pay to AMX: (i) up to US$500 million as an earn-out six-month earn-out TracFone was deconsolidated from that date resulting in a net gain of Ps. 106,527,287 including the recycling of foreign currency exchange losses accumulated in equity. This gain has been recognized under profit after tax from discontinued operations in the consolidated statements of comprehensive income. Furthermore, no impairment loss was identified. Moreover, TracFone had identifiable operations and cash flows and represented a separate geographical area. Therefore, in accordance with IFRS 5, TracFone was classified as discontinued operations for all years presented in these consolidated financial statements; results are accordingly presented in the profit after tax from discontinued operations in the consolidated statements of comprehensive income. The consolidated statements of comprehensive income comparative figures have therefore been restated accordingly, at that time. All other notes to the consolidated financial statements include amounts for continuing operations, unless indicated otherwise. Additionally, TracFone represented the U.S.A. segment until November 23, 2021. With TracFone being classified as discontinued operations, the U.S.A. segment is no longer presented in the segment note. The results of TracFone for the year are presented below:  For the years ended 2021 Operating revenues: Service revenues Ps.130,091,540 Sales of equipment 22,160,481 152,252,021 Total costs and expenses 134,495,316 Operating income 17,756,705 Financial cost (1,733 ) Gain on disposal of discontinued operations 132,821,709 Profit before income tax discontinued operations 150,576,681 Tax expense: Related to pre-tax 2,571,541 Related to gain on disposal from discontinued operations 26,294,422 Net profit for the year from discontinued operations Ps.121,710,718 The assets and liabilities deconsolidated on the date of the disposal were as follows: November 23, 2021 Current assets Cash Ps. 338,439 Subscribers, distributors, recoverable taxes, contract assets and other net 12,368,407 Inventories, net 9,604,658 Other current assets, net 389,052 Total current assets 22,700,556 Non-current Property, plant and equipment 1,989,498 Intangibles, net 555,012 Goodwill 2,695,557 Deferred income taxes 1,094,756 Other assets, net 327,546 Rights of use 1,625 Total assets Ps. 29,364,550 Short term liability related to right of use of assets Ps. 1,625 Accounts payable 17,446,513 Income tax 3,267,585 Deferred revenue 13,187,667 Total liabilities 33,903,390 Net liability directly associated with disposal group Ps.

Service award description	Civil servants and certain employees (in the following “employees”) are eligible to receive service awards. In accordance with the legal regulations, eligible employees receive a cash bonus of two months’ salary after 25 years of service and four months’ salary after 40 years of service. Employees with at least 35 years of service when retiring (at the age of 65) or who are retiring based on specific legal regulations are also eligible to receive the service award of four monthly salaries. The obligation is accrued over the period of service, taking into account the employee turnover rate for employees who leave employment prematurely.
