The deferred tax assets are in tax jurisdictions in which the Company considers that based on financial projections of its cash flows, results of operations and synergies between subsidiaries, will generate sufficient taxable income in subsequent periods to utilize or realize such assets.

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,

associate and joint venture, for which a deferred tax liability has not been recognized in the periods presented, aggregate to Ps 218,859,473 and Ps. 187,830,823 as of December 31, 2021 and 2022, respectively.

At December 31, 2021 and 2022, the balance of the contributed capital account (“CUCA”) is Ps. 612,351,412 and Ps. 654,631,901 respectively. Effectively, on January 1, 2014, the

Cuenta de Utilidad Fiscal Neta

(“CUFIN”) is computed on an América Móvil’s stand-alone basis. The balance of the América Móvil’s stand-alone basis CUFIN amounted to Ps. 431,249,107 and Ps. 533,076,863as of December 31, 2021 and 2022, respectively.

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 prof

of this transaction was Ps. 93,968,555.

ii) Significant foreign income tax matters

Results of operations

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 16.2% in 2020, 19.3% in 2021 and 17.4% in 2022. 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 2020, 2021 and 2022 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 and Impairment related to subsidiaries in Europe.

a.1

) In 2021, The Brazilian Federal Supreme Court’s (STF) ruled in favor of a third party’ thesis related to the unconstitutionality of incidence of the IRPJ (Income Tax in Brazil) and CSLL (Social Contribution over Net Profit in Brazil) on the amounts corresponding to the SELIC (Special settlement and custody system) rate received for repetition of the tax that should not be applicable, such thesis being similar to the thesis filed by subsidiaries of the Company in Brazil.

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)

In 2020,Claro S.A. began to use the tax benefit related to the ICMS Grant on TV based on Complementary Law 160/2017 and art. 30 of Law 12,973, as well as in recent interpretations on the subject, investment grants are not computed in determining actual profit in the amount of Ps. 1,721,453 (R$411,336). In 2021 the tax benefit was Ps. 1,431,164 (R$380,373) and 2022 Ps.1,163,081 (R$297,880).

iii) Tax losses

a) At December 31, 2022, the available tax loss carryforwards recorded in deferred tax assets are as follows on a country by country basis:


Country	Gross balance of available tax loss carryforwards at December 31, 2022		Tax-effected loss carryforward benefit
Brazil	Ps.	72,498,097	Ps.	24,649,353
Mexico		26,969,956		8,090,987
Europe		1,882,415		470,604
Peru		345,697		103,709

Total	Ps.	101,696,165	Ps.	33,314,653

The tax loss carryforwards in the different countries in which the Company operates have the following terms and characteristics:

bi)

The Company has accumulated Ps. 72,498,097 in net operating loss carryforwards (NOL’s) in Brazil as of December 31, 2022. In Brazil, there is no expiration of the NOL’s. The NOL´s amount used against taxable income in each year may not exceed 30% of the taxable income for such year.

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)

The Company has accumulated Ps. 26,969,956 in tax losses in Mexico. The company estimates that there is positive evidence that allows it to use these losses, these should be reduced to the extent that it is considered likely that there will

not

be sufficient taxable profits to allow them to recover in full or in part, the losses will only be compensated when there is a right legally required and are approved by the tax authorities in Mexico.

biii)

The Company has accumulated Ps. 1,882,415 in NOL’s in Europe as of December 31, 2022. In Europe, the NOL´s have no expiration, but its annual usage is limited to 75% of the taxable income of the year. The realization of deferred tax assets is dependent upon the expected generation of future taxable income during the periods in which these temporary differences become deductible.

biv)

The Company has tax losses reserved as of December 31 2022 for an amount of Ps. 14,701,405, which correspond to Telmex and Brazil.

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.

vi) 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 Base Erosion and Profit Shifting (BEPS) project issued by the Organization for Economic Co-operation and Development (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.
