“América Móvil informs about a resolution of

the Instituto Federal de Telecomunicaciones”

Mexico City, December 7, 2020. América Móvil, S.A.B. de C.V. ("AMX") [BMV: AMX] [NYSE: AMX | AMOV], informs that it received a resolution issued by the Federal Telecommunications Institute (Instituto Federal de Telecomunicaciones or “IFT”) related to its second “biennial” evaluation of the asymmetrical regulations imposed on March 2014 to Radiomóvil Dipsa, S.A. de C.V. (“Telcel”), Teléfonos de México, S.A.B. de C.V. (“Telmex”), and Teléfonos del Noreste, S.A. de C.V. (“Telnor”), entities that are part of the denominated “preponderant economic agent” (agente económico preponderante or “AEP”) in the telecommunications sector.

This resolution determines to suppress certain asymmetrical regulations, as well as to modify and add new asymmetrical regulations, for mobile and fixed services.

For fixed services, in general terms, it resolved: (i) the use of a long-run average incemental costs model to determine the local loop indirect access services rates, and that IFT may determine competitive geographic zones where such rates will be determined by the AEP; (ii) for dedicated-link leasing services, the IFT may determine competitive geographic zones and/or competitive dedicated-links where dedicated-link leasing rates will be determined pursuant to a price cap methodology, considering, among others, the number of operators providing services, market share and existing network infrastructure in such geographic zones; and (iii) certain operative and informational modifications to the electronic management system (sistema electrónico de gestión).

In the mobile segment, the main additions and modifications are related with: (i) detail of information required for rate economic replicability analysis; (ii) rules applicable to installment purchase of handsets by Telcel’s end users; and (iii) various new information reports to be provided to the IFT.

AMX believes that, again, IFT’s resolution is not based on an integral evaluation in terms of competition of the different markets in the Mexican telecommunications sector, nor does it consider the profound changes in the Mexican telecommunications sector within six years from the imposition of the asymmetric regulations and the effective competition that exists in fixed and mobile services.

AMX is currently reviewing the resolution and analyzing its possible effects on AMX and its subsidiaries. The resolution will be challenged in accordance with applicable law.
