“América Móvil informs about a resolution

of the Instituto Federal de Telecomunicaciones”

Mexico City, March 8, 2017. América Móvil, S.A.B. de C.V. ("AMX") [BMV: AMX] [NYSE: AMX | AMOV] [LATIBEX: XAMXL], announces that it received a resolution issued by the Federal Telecommunications Institute (Instituto Federal de Telecomunicaciones or “IFT”) related to its “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) in the telecommunications sector.

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

Mobile Services

For mobile services, the main modifications and additions refer to: (a) the inclusion of equivalence of inputs and technical replicability principles applicable to the terms under which wholesale regulated services are provided for the commercialization of mobile services to mobile virtual network operators and to the terms under which wholesale roaming services are provided; (b) the inclusion of an ex-post regulation granting IFT the right to verify the economic replicability of the end users rates with respect to rates applicable to services provided by mobile virtual network operators; and (c) the reinforcement of regulations to guarantee access to information about infrastructure and services related to regulated wholesale services, through the electronic management system (sistema electrónico de gestión).

Fixed Services

For fixed services, the main modifications and additions refer to: (i) the inclusion of equivalence of inputs, technical and economic replicability principles applicable to the terms under which wholesale regulated fixed services are provided, including those applicable to the shared access and use of passive infrastructure and to local loop unbundling; (ii) the inclusion of a regulation granting IFT the right to verify ex-ante or ex-post the economic replicability of the end users rates; (iii) with respect to rates applicable to wholesale dedicated-link leasing services the costs methodology for the determination of such rates changes from a retail minus methodology to a long-run average incremental costs methodology; (iv) based on costs models, IFT will determine the rates applicable to all wholesale regulated fixed services; (v) the reinforcement of regulations to guarantee access to information about infrastructure and services related to regulated wholesale services, through the electronic management system (sistema electrónico de gestión); and (vi) an order to implement a functional separation of the provision of wholesale regulated fixed services.

Functional Separation

With respect to the functional separation of the provision of wholesale regulated fixed services, the IFT ordered the incorporation of a legal entity independent from Telmex-Telnor that will exclusively provide wholesale services related to local loop (acceso local) and shared access and use of passive infrastructure. All other wholesale services will be provided by a business unit within Telmex-Telnor different from the one that provides telecommunication services to end users. Implementation of the functional separation will be based on a separation plan that will be presented by Telmex-Telnor for IFT approval, under the terms and conditions determined by the IFT.

AMX believes that IFT resolution is not based on an integral evaluation in terms of competition, nor does it consider the profound changes in the Mexican telecommunications sector within three years from the imposition of the asymmetric regulations and the effective competition that exists in mobile and fixed services, which is clearly shown, amongst others, by the significant growth in the consumption of telecommunication services, mainly data. The notified modifications and additions to the regulations violate the concessions and confirm the lack of legal certainty and regulatory predictability in the sector.

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.
