Tax report of

Grupo Aeroportuario del Sureste, S.A.B. de C.V. corresponding to year 2024

[CONVENIENCE TRANSLATION]

Report on Other Legal and Regulatory Requirements

Report on Review of Taxpayer’s Fiscal Situation

To the Board of Directors and the Shareholders of Grupo Aeroportuario del Sureste, S.A.B. de C.V. To the Ministry of Finance and Public Credit

To the Tax Administration Service (Servicio de Administración Tributaria or SAT)

To the General Federal Tax Auditing Administration (Administración General de Auditoría Fiscal Federal)

  1. I am issuing this report in relation to the audit I have carried out in accordance with International Auditing Regulations (NIAs) of the financial statements prepared by the management of Grupo Aeroportuario del Sureste, S.A.B. de C.V., as required under Article 32-A of the Federal Tax Code (Código Fiscal de la Federación or CFF); Article 58, Sections I, IV and V, of the Regulations of the CFF (Reglamento del CFF or RCFF); Rules 2.10.6, 2.10.14 and 2.10.15 of the Miscellaneous Tax Resolution for 2025 (Resolución Miscelánea Fiscal or RMF); and the instructions for data calculations and characteristics and guidance formats for the presentation of reports on audited financial statements for tax purposes contained in Appendix 16 of the RMF. An audit conducted in accordance with NIAs provides a reasonable degree of assurance; however, it does not guarantee detection of any possible omissions, errors or acts that might constitute the commission of a tax offence, as it is not designed for that purpose.

    Based on the audit I performed, I issued an audit report with unqualified opinion, dated the 13thof May 2025.

  2. Exclusively with reference to the matters mentioned in this Section 2, I hereby provide a sworn statement, in accordance with Article 52, Section III, of the CFF; Articles 57 and 58, Section III, of the RCFF; and Rule 2.10.15 of the RMF, to the effect that: as part of my audit, as described in Section 1 above, I reviewed additional information and documentation prepared by and under the responsibility of the Company, in accordance with Article 32-A of the CFF; Article 58, Sections I, IV and V, of the RCFF; Rules 2.10.6, 2.10.7 and 2.10.14 of the RMF; and the instructions for data calculations and characteristics and guidance formats for the presentation of reports on audited financial statements for tax purposes contained in Appendix 16 of the RMF, which has been presented via the Tax Report Presentation System 2024 (SIPRED) via the Internet to the SAT. I audited this information and documentation using selective testing, according to the auditing procedures and scopes I considered appropriate under the circumstances, based on my professional opinion. I believe that the audit evidence I have obtained provides a sufficient and appropriate basis that supports my opinion, as per NIAs, with regard to the financial statements as a whole. This information is attached for the analysis and exclusive use of the Decentralized Tax Auditing Administration (Administración Desconcentrada de Auditoría Fiscal) for Grupo Aeroportuario del Sureste, S.A.B. de C.V. On the basis of my audit, I hereby state the following:

    1. As part of the selective testing carried out in compliance with the NIAs, I reviewed the fiscal situation of the taxpayer, as defined in Article 58, Section V, of the RCFF, for the period covered by the audited financial statements. Within the scope of the selective testing I performed, I ascertained that the goods and services acquired or provided for use or usufruct by the Company during the year were in fact received, issued or rendered, respectively. In accordance with Section II of Rule 2.10.15 of the RMF, the procedures I applied did not include reviews of compliance with customs or external-trade provisions.

      My audit documentation contains evidence of the auditing procedures applied for each item sampled, which support the conclusions obtained.

    2. On the basis of selective testing and the NIAs, I verified calculation and payment of the federal taxes incurred during the year, including taxes payable by the taxpayer as a direct subject and taxes payable as a withholder.

      Due to the fact that the Company has no employees, there is no requirement to pay social security contributions to the Mexican Social Security Institute (Instituto Mexicano del Seguro Social or IMSS) arising from wages and salaries.

    3. During the period under review, I was not made aware that the taxpayer requested the reimbursement of rebates and/or compensations. As of the 31stof December 2024, there are no sums pending rebate or compensation.

    4. In accordance with their nature and the application methods used in previous years, as applicable, I also verified the concepts and sums corresponding to the year ending the 31stof December 2024 contained in the following appendices:

      • Reconciliation between accounting and tax results for the purpose of calculating income tax (Impuesto Sobre la Renta or ISR), and

      • Reconciliation between the revenues audited according to the profit and loss statement, taxable revenues for the purposes of ISR, and the total resulting from all activities for the purposes of value-added tax (Impuesto al Valor Agregado or IVA).

    5. During the period, I was not made aware of the presentation by the taxpayer of any complementary tax returns that modified the information submitted in previous periods. I also reviewed the complementary tax returns of which I was made aware, presented by the taxpayer to account for tax differences in the period under audit, and verified that they were presented in accordance with the relevant tax regulations.

    6. Due to the fact that the Company has no employees, Worker Profit Shares were not calculated or paid out.

    7. Using selective testing, I reviewed the balances as of the 31stof December 2024 of the accounts indicated in the appendices on the comparative analysis of expense sub-accounts and on the comparative analysis of integral financing results sub-accounts, and reconciled, when applicable: a) differences with base financial statements arising from reclassification for presentation, and b) the calculation of deductible and non-deductible sums for the purposes of ISR.

    8. I was not made aware of any instances in which the Company obtained resolutions from the tax or jurisdictional authorities, exemptions, subsidies or tax credits during the year ending the 31stof December 2024. I reviewed the information relating to tax incentives applied during the period, which are disclosed in the tax returns authorized by the taxpayer’s legal representative.

    9. During the period, and as a result of by audit testing, I did not observe any instance in which the Company had any joint liability for withholding taxes as a result of any sale of shares carried out by parties resident abroad.

    10. During the period under audit, exchange-rate earnings or losses due to fluctuations in foreign currencies were not part of my remit, due to the fact that they are immaterial in the context of the financial statements taken as a whole.

    11. The sums of the transactions carried out by the Company with its main related parties during the year ending the 31stof December 2024 are stated in Note 8 of the financial statements, attached as the appendix “Notes to the Financial Statements” in SIPRED. The transactions with related parties carried out during the period are stated in the appendix “Transactions with Related Parties” in SIPRED.

      As part of my random testing, I reviewed compliance with the obligations relating to transactions with related parties, as required under the following provisions: Articles 11, 27, Section XIII, 28, Sections XVII, paragraph four, point b), XVIII, XXVII, and XXIX, and 76, Sections IX, X and XII of the Income Tax Law.

    12. During the period ending 31stDecember 2024, the Company disclosed information in the SIPRED General Information Appendix relating to the application of certain criteria different to those that may have been published by the tax authorities in Subsection h) of Section I of Article 33 of the CFF in force as of the 31stof December 2024. In the appendix in question, the taxpayer stated that said criteria had not been applied during the period ending 31stDecember 2024.

    13. As part of my selective testing, I reviewed the information disclosed by the taxpayer in the representations presented in compliance with its obligations under the following fiscal provisions, without observing any omissions therein:

      • Appendix 76, Section VI, of the Income Tax Law “Information on Foreign Residents” (Appendix 4 of the DIM).

      • Article 9 of the Transitional Provisions of the Income Tax Law for 2014, section X, “Information on Payment and Withholding of ISR, IVA and IEPS” (Appendix 2 of the DIM), referring to withholdings on payments made to parties resident abroad. Appendix 76, Section III, of the Income Tax Law “Information on Withholdings on Foreign Residents Stated on CFDIs”.

  3. It is important to take note that a public accountant does not have the professional training or the legal capacity to determine and/or assess those actions that may constitute the commission of a tax crime. Therefore, in all cases it remains the responsibility of the competent authorities to legally determine the existence or not of any supposed action that may amount to a tax crime.

    Other Matters

  4. My responses in relation to the tax diagnosis and transfer pricing questionnaires that are included in the information in SIPRED are based on the results of my audit of the base financial statements of Grupo Aeroportuario del Sureste,

    S.A.B. de C.V. as of the 31stof December 2024 and for the year leading up to that date, taken as a whole, which was performed according to NIAs. Consequently, the responses that indicate compliance with tax regulations by the taxpayer are based on: a) the results of the audit that I performed on the basis of NIAs, or b) the fact that during the audit I performed in accordance with NIAs, I reviewed and did not detect any instances of non-compliance on the part of the taxpayer with its fiscal obligations.

    Some of the responses to questions in the tax diagnosis questionnaire and the transfer pricing questionnaire were left blank, due to the fact that: 1) they are not applicable to the Company, 2) there is no possible answer, or 3) the information was not reviewed as it did not fall under the scope of my audit, which does not constitute non-compliance with tax provisions.

  5. Regarding the responses that the Company has provided to the tax diagnosis and transfer pricing questionnaires included in the appendices “General Information” and “Taxpayer Information on Transactions with Related Parties”, respectively, which form part of the information included in SPIRED, I have reviewed these responses and verified that they are consistent with the results of the audit I performed in accordance with NIAs.

    Consequently, the responses that indicate compliance with tax obligations by the taxpayer are supported by the fact that during the audit I performed, I reviewed and detected no instances of noncompliance with the tax obligations referred to in the questionnaires.

    Certain questions require information that is not part of the base financial statements, and consequently the responses were provided by the taxpayer and do not fall under the scope of my audit.

    Instances of non-compliance that are non-material and/or which do not affect federal taxes and contributions

  6. As of the 31stof December 2024, no differences in taxes or contributions were identified that must be disclosed in the column “Non-Material Differences Not Investigated in Audit” in Appendix “List of Contributions Paid by Taxpayer as Direct Payer and as Withholder”.

Proposal for application of retained earnings of Grupo Aeroportuario del Sureste, S.A.B. de C.V. as of yearend 2025; Proposal to increase legal reserve

Grupo Aeroportuario del Sureste, S.A.B. de C.V. Proposal to increase legal reserve

Under Mexican law, ASUR and each of its subsidiaries are required to set aside a minimum of 5% of net annual profits to increase the legal reserve until it reaches the equivalent of 20% of the outstanding capital stock (historical) of the company in question. Mexican companies may only pay dividends from retained earnings after the legal reserve has been set aside.

Consequently, in 2026 ASUR will have to increase the legal reserve by Ps. $6.00 (six pesos and zero cents, Mexican legal tender), with the corresponding deduction from accumulated retained earnings from 2025.

This proposal has been approved by the Company’s Strategic Partner, the Company’s

Operations Committee, and the Company’s Board of Directors.
