*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 MXN Notes prior to the date that is one business day prior to the date of delivery of the MXN Notes will be required, by virtue of the fact that the MXN Notes initially will settle in four business days (T+4), 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).

Capitalized terms used and not defined in this final term sheet have the meanings assigned to such terms in the Issuer’s preliminary prospectus supplement dated November 18, 2025 relating to the MXN Notes (the “Prospectus Supplement”) which has been filed with the SEC under Registration No. 333-287731.

PROHIBITION OF SALES TO EEA RETAIL INVESTORS – The MXN Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (the “EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the MXN Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the MXN Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

PROHIBITION OF SALES TO UK RETAIL INVESTORS – The MXN Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (the “UK”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (the “EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, the “FSMA”) and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of the Prospectus Regulation as it forms part of domestic law by virtue of the EUWA. Consequently, no key information document required by the PRIIPs Regulation as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the MXN Notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the MXN Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.
