Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time. Each securities rating should be evaluated independent of each other securities rating.

*Under Rule 15c6-1 of the U.S. Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the date that is one business day prior to the date of the delivery of the Notes may be required, by virtue of the fact that the Notes initially will settle in three business days (T+3), to specify alternative settlement arrangements to prevent a failed settlement.

The offer and sale of the securities to which this final term sheet relates have been registered by América Móvil, S.A.B. de C.V. with the U.S. Securities and Exchange Commission (the “SEC”) by means of a registration statement on Form F-3 (Registration No. 333-287731).

Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.
