“América Móvil Informs about Mexican Supreme Court Resolution”

Mexico City, August 16, 2017. América Móvil, S.A.B. de C.V. ("AMX") [BMV: AMX] [NYSE: AMX | AMOV], informs that today the Second Chamber (Segunda Sala) of the Mexican Supreme Court of Justice, in an unanimous vote, resolved to grant an injunction (amparo) to its subsidiary Radiomóvil Dipsa, S.A. de C.V. (“Telcel”) against a series of provisions of the Federal Telecommunications and Broadcasting Law (Ley Federal de Telecomunicaciones y Radiodifusión or “Implementing Legislation”) in relation to the prohibition imposed on Telcel to charge other carriers for termination services on its network, commonly referred to as the “Zero Rate”. In other words, the Supreme Court resolved that such interconnection regime set forth in the Implementing Legislation is unconstitutional.

Through this important resolution, the Supreme Court restores the authority of the Federal Telecommunications Institute (Instituto Federal de Telecomunicaciones, or “IFT”) to determine the interconnection rate that other carriers shall pay Telcel for the termination of services on its network. Such rate shall be based on international best practices, cost oriented methodologies, transparency and rationality.

Notwithstanding the unconstitutionality of the “Zero Rate”, the Second Chamber (Segunda Sala) of the Supreme Court resolved (i) that other carriers shall not restore Telcel for the adverse effects caused by the “Zero Rate” since August 2014; and (ii) that the interconnection rate that other carriers shall pay Telcel for termination services on its network as established by the IFT shall be effective on January 1, 2018.
