The major maintenance provision expense was Ps.50.4 million. The outstanding balance of the maintenance provision as of June 30, 2025, was Ps.2,538 million.

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

In relation to the change in the rate from 5.0% to 9.0% applied to the revenues generated by OMA’s airport concessions, pursuant to the Mexican Federal Duties Law, effective as of January 1, 2024, in the second quarter of 2025, the 4% excess of Concession Tax levied on aeronautical revenues amounted to Ps.109.3 million, equivalent to 3.2% of the sum of OMA’s aeronautical and non-aeronautical revenues. This amount is included within the Ps.282.6 million recorded as Concession Tax expense in 2Q25. Under the Tariff Regulation Bases effective as of October 20, 2023, payments made to the government related to aeronautical revenues, in excess of those included in 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 the maximum tariff.

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

Totaloperating costs and expenses increased 30.9%.

Financing Expense and Net Income

FinancingExpense was Ps.408 million compared to Ps.134 million in 2Q24. The increase is primarily due to a higher non-cash interest expense of Ps.130 million resulting mainly from a change in the present value of the major maintenance provision of Ps.59.8 million, as a result of a decrease in the discount rates used for its calculation.

Notes to the Financial Information

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

Unless stated otherwise, all comparisons of operating or financial results are made with respect to the comparable period of 2024. The exchange 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 operators should account for the obligations they undertake and rights they receive in service concession arrangements. The concession contracts for each of OMA’s airport subsidiaries establishes that the concessionaire is obligated to carry out improvements to the infrastructure transferred in exchange for the rights over the concession granted by the Federal Government. The latter will receive all the assets at the end of the concession period. As a result, the concessionaire should recognize, using the percentage of completion method, the revenues and costs associated with the improvements to the concessioned assets. The amount of the revenues and costs so recognized should be the price that the concessionaire pays or would pay in an arm’s length transaction for the 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 based on total revenues.

Capitalinvestments: includes investments in fixed assets (including investments in land, machinery, and equipment) and improvements to 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 passengers on the three types of aviation (commercial, charter, and general aviation), and excludes passengers in transit. The definition of 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 expense and maintenance provision. We calculate the Adjusted EBITDA margin as Adjusted EBITDA divided by the sum of aeronautical revenue and non-aeronautical revenue. Construction revenue and construction cost do not affect cash flow generation and the maintenance provision 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 as an indicator of our operating performance, or as an alternative to cash flow as an indicator of liquidity. It should be noted that neither Adjusted EBITDA nor EBITDA is defined under IFRS, and may be calculated differently by different companies.
