State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

On April 24, 2025, América Móvil, S.A.B. de C.V. (the “Company”) was notified by Mancera S.C. (the “Firm”), the Company’s independent registered public accounting firm, that the Firm requires additional time to complete the audit of the Company’s financial statements for the fiscal year ended December 31, 2024, and its assessment of internal control over financial reporting as it engages in additional audit procedures related to its “Mexico Fixed” and “Mexico Wireless” segments. As a result, the Company has determined that it is unable to file its Annual Report on Form 20-F for the fiscal year ended December 31, 2024 (the “2024 Form 20-F”) by the prescribed due date without unreasonable effort or expense. The Company expects to file its 2024 Form 20-F within the 15 calendar day extension provided by Rule 12b-25, but can provide no assurance that it will be able to file by such time.

The Company does not anticipate any material changes to the selected financial information furnished with the Form 6-K filed by the Company on February 13, 2025.

Attached hereto and filed as Exhibit 99.1 to this Form 12b-25 is the statement of the Firm as contemplated by Rule 12b-25(c).
