Themajor maintenance provision expense was Ps.50.4 million. The outstanding balance of the maintenance provision as of June30, 2025, was Ps.2,538 million.

Theairport concession tax increased 18.1% to Ps.282.6 million, as a result of the increase in revenues.

Inrelation to the change in the rate from 5.0% to 9.0% applied to the revenues generated by OMA’s airport concessions, pursuantto the Mexican Federal Duties Law, effective as of January 1, 2024, in the second quarter of 2025, the 4% excess of ConcessionTax levied on aeronautical revenues amounted to Ps.109.3 million, equivalent to 3.2% of the sum of OMA’s aeronautical and non-aeronauticalrevenues. This amount is included within the Ps.282.6 million recorded as Concession Tax expense in 2Q25. Under the Tariff RegulationBases effective as of October 20, 2023, payments made to the government related to aeronautical revenues, in excess of those includedin the most recent tariff revision, will be added to the reference value to be used in the next joint maximum tariff revision.Therefore, starting in January 2026, these excess airport concession taxes amounts paid will begin to be recovered through themaximum tariff.

Thetechnical assistance fee was Ps.67.0 million, 20.2% higher, due to an increase in the EBITDA.

Totaloperating costs and expenses increased 30.9%.

Notesto the Financial Information

Financialstatements are prepared in accordance with International Financial Reporting Standards (“IFRS”), and presented inaccordance with IAS 34 “Interim Financial Reporting.” For more information, please refer to our Quarterly FinancialInformation submitted to the Mexican Stock Exchange (www.bmv.com.mx)

Unlessstated otherwise, all comparisons of operating or financial results are made with respect to the comparable period of 2024. Theexchange rates used to convert foreign currency amounts were Ps.18.3773 as of June 30, 2024, and Ps.18.8483 as of June 30, 2025.

Constructionrevenue, construction cost: IFRIC 12 “Service Concession Arrangements” addresses how service concession operatorsshould account for the obligations they undertake and rights they receive in service concession arrangements. The concession contractsfor each of OMA’s airport subsidiaries establishes that the concessionaire is obligated to carry out improvements to theinfrastructure transferred in exchange for the rights over the concession granted by the Federal Government. The latter will receiveall the assets at the end of the concession period. As a result, the concessionaire should recognize, using the percentage ofcompletion method, the revenues and costs associated with the improvements to the concessioned assets. The amount of the revenuesand costs so recognized should be the price that the concessionaire pays or would pay in an arm’s length transaction forthe execution of the works or the purchase of machinery and equipment, with no profit recognized for the construction or improvement.The application of IFRIC 12 does not affect operating income, net income, or EBITDA, but does affect calculations of margins basedon total revenues.

Capitalinvestments: includes investments in fixed assets (including investments in land, machinery, and equipment) and improvementsto concessioned properties under the Master Development Plan (MDP) plus strategic investments.

StrategicInvestments: Refers only to those capital investments additional to the Master Development Program.

Passengersand Terminal passengers: All references to passenger traffic volumes are to Terminal passengers, which includes passengerson the three types of aviation (commercial, charter, and general aviation), and excludes passengers in transit. The definitionof terminal passengers of OMA may differ from the definition utilized by its shareholder VINCI Airports.

AdjustedEBITDA and Adjusted EBITDA margin: OMA defines Adjusted EBITDA as EBITDA less construction revenue plus construction expenseand maintenance provision. We calculate the Adjusted EBITDA margin as Adjusted EBITDA divided by the sum of aeronautical revenueand non-aeronautical revenue. Construction revenue and construction cost do not affect cash flow generation and the maintenanceprovision corresponds to capital investments. OMA defines EBITDA as net income minus net comprehensive financing income, taxes,and depreciation and amortization. Neither Adjusted EBITDA nor EBITDA should be considered as an alternative to net income asan indicator of our operating performance, or as an alternative to cash flow as an indicator of liquidity. It should be notedthat neither Adjusted EBITDA nor EBITDA is defined under IFRS, and may be calculated differently by different companies.
