- Regulator: Comision Nacional Bancaria y de Valores (CNBV) - issues the 'Disposiciones de caracter general aplicables a las emisoras de valores y a otros participantes del mercado de valores' (Circular Unica de Emisoras, CUE), published in the DOF 19 March 2003, last amended 2 July 2026 per the document header. CNBV's own 'about' pages were not readable (TLS/anti-bot errors) (source: https://www.cnbv.gob.mx/Normatividad/Disposiciones%20de%20car%C3%A1cter%20general%20aplicables%20a%20las%20emisoras%20de%20valores%20y%20a%20otros%20participantes%20del%20mercado%20de%20valores.pdf)
- Exchange(s) and listings page: [{"name":"Bolsa Mexicana de Valores (BMV) - cash, listed derivatives and OTC markets; equities, fixed income, ETFs","listings_page":"https://www.bmv.com.mx/en/issuers/issuers-information"},{"name":"Bolsa Institucional de Valores (BIVA)","listings_page":"https://www.biva.mx/"}] (source: https://www.bmv.com.mx/en/bmv-group/about-us ; https://www.bmv.com.mx/en/issuers/issuers-information ; https://www.biva.mx/)
- Regulated-information store: Events relevant (eventos relevantes) are transmitted to the exchange through SEDI and then, the same date, to CNBV through STIV-2; public reading on the exchange sites (BMV EMISNET / Outstanding Events; BIVA eventos relevantes). BMV page for outstanding events displays only 2014 items in the capture (source: CUE art. 50 (CNBV PDF above) ; https://www.bmv.com.mx/en/issuers/issuers-information (links EMISNET) ; https://www.bmv.com.mx/en/investor-relations/outstanding-events)
- Periodic disclosure obligations and deadlines: [{"report":"Annual report (reporte anual), CUE art. 33 I b)","deadline":"A mas tardar el 30 de abril de cada ano (reporte anual del ejercicio social inmediato anterior)"},{"report":"Annual audited financial statements / board report, CUE art. 33 I a)","deadline":"El tercer dia habil inmediato siguiente a la fecha de celebracion de la asamblea general ordinaria de accionistas ... que debera efectuarse dentro de los 4 meses posteriores al cierre de dicho ejercicio"},{"report":"Quarterly information, CUE art. 33 II","deadline":"Dentro del mes inmediato siguiente a la terminacion de cada uno de los primeros trimestres del ejercicio social y dentro de los 40 dias habiles siguientes a la conclusion del cuarto trimestre (Q4 figures preliminary until audited statements are filed); the one-month and 40-business-day periods do not apply to sociedades anonimas promotoras de inversion bursatil, and trust issuers have a 20-business-day regime"}] (source: https://www.cnbv.gob.mx/Normatividad/Disposiciones%20de%20car%C3%A1cter%20general%20aplicables%20a%20las%20emisoras%20de%20valores%20y%20a%20otros%20participantes%20del%20mercado%20de%20valores.pdf (CUE art. 33))
- Ad hoc / inside-information regime: CUE art. 50: issuers must transmit relevant events (eventos relevantes) to the exchange where listed through SEDI and then, on the same date, to CNBV through STIV-2; art. 51: deferral of disclosure permitted under art. 105 of the Ley del Mercado de Valores with an insider access register; art. 54: exchange must immediately require more information on relevant events that are insufficient, imprecise or confusing. The CUE text read does not itself state a clock beyond transmission to the exchange (the 'inmediata' standard sits in the LMV, not read) (source: https://www.cnbv.gob.mx/Normatividad/Disposiciones%20de%20car%C3%A1cter%20general%20aplicables%20a%20las%20emisoras%20de%20valores%20y%20a%20otros%20participantes%20del%20mercado%20de%20valores.pdf)
- Filing format: Electronic formats (formatos electronicos) filed via STIV-2 / SEDI; BMV publishes XBRL taxonomy packages (.XSD) by issuer type (industrial/commercial/service issuers, FIBRAs and SAPIB, debt/referenced/capital certificate trusts). The page does not state who must file in XBRL (source: https://www.bmv.com.mx/en/listed-issuers/xbrl-financial-information ; CUE art. 33 II (formatos electronicos))
- ISIN prefix: MX - Indeval (central securities depository). Indeval page lists 'ISIN (International Security Identification Number) Code Assignment' and states 'Indeval joins ANNA (Association of National Numbering Agencies)' in 1993; the term 'national numbering agency' is not used on those pages (source: https://www.indeval.com.mx/en/history ; https://www.indeval.com.mx/en/about-us)
- LEI: LEI = 20-character ISO 17442 code issued by GLEIF-accredited LEI Issuers (LOUs); searchable in the Global LEI Index. No Mexico-specific LEI issuer or issuer obligation read on an official page (source: https://www.gleif.org/en/about-lei/introducing-the-legal-entity-identifier-lei)
