“América Móvil informs to the market”

Mexico City, Mexico, June 25, 2014. América Móvil, S.A.B. de C.V. (“AMX” or “América Móvil”) (BMV: AMX; NYSE: AMX; NASDAQ: AMOV; LATIBEX: XAMXL), informs that, since the effective date of the constitutional amendment enacted in June 2013 with respect to the Mexican telecommunications and broadcasting sectors, it has been assessing the scope and potential effects of such amendment, including but not limited to, the concept of “preponderance” in the telecommunications sector.

As América Móvil communicated in March 2014, the Federal Telecommunications Institute (Instituto Federal de Telecomunicaciones, or “IFT”), determined an economic interest group comprised of AMX and its operating subsidiaries Radiomóvil Dipsa, S.A. de C.V. (“Telcel”) and Teléfonos de México, S.A.B. de C.V. (“Telmex”), as a preponderant economic agent in the telecommunications sector under the premise that, as of June 2013, these entities accounted for 61.8% of the aggregate number of subscribers in such sector, and imposed upon such entities certain specific asymmetrical regulations that are being implemented in accordance with the IFT resolution. América Móvil has challenged the determination as to preponderance, its effects and related measures.

América Móvil is awaiting the discussion and approval of the implementing legislation as with respect to the telecommunications and broadcasting sectors that was submitted this past March to the Mexican Congress.

Based on the foregoing, América Móvil has created a strategic committee to assess the various structural, commercial, technological and other options available to it, as well as the opportunities offered by the new Mexican regulatory framework, in order to continue with the development of the telecommunications sector and providing services with high quality, state-of-the-art technologies and under best conditions.

The results of and recommendations arising from the committee will be made available to América Movil’s board of directors and, as the case may be, its shareholders’ meeting, for discussion.
