Consolidated Financial Results

Revenues

Aeronautical revenues increased 5.6%.

Non-aeronautical revenues increased 7.5%.

Commercial revenues increased 8.4%, while commercial revenues per passenger reached Ps.61.7, an increase of 2.2% versus 4Q24. The line items with the largest increases were:

▪

Parking, +18.4%, driven by an increase in passenger traffic, higher penetration, and higher tariffs.

▪

Restaurants, +11.3%, driven by greater penetration and opening or replacement of outlets in previous quarters, as well as higher passenger traffic.

▪

VIP Lounges, +17.0%, Due to greater market penetration, primarily at the Monterrey Airport, and an increase in passenger traffic.

▪

Retail, +7.0%, driven by higher penetration and the opening or replacement of outlets in previous quarters, as well as the increase in passenger traffic.

Diversification revenues increased 4.8%, mainly due to higher revenues from OMA Carga.

Construction revenues represent the value of improvements to concessioned assets. They are equal to construction costs and generate neither a gain nor a loss. Construction revenues and costs are determined based on the advance in the execution of projects in accordance with the airports’ Master Development Programs (MDP), and variations depend on the rate of project execution.

Costs and Operating Expenses

The sum of cost of airport services and general and administrative expenses (G&A) increased 11.6% as compared to 4Q24, mainly due to increases in minor maintenance, contracted security and cleaning services, as well as utilities, mainly energy costs.

The major maintenance provision expense was Ps.216.3 million. In the fourth quarter, OMA recognized the effects of the update to major maintenance requirements included in its Master Development Programs for the 2026–2030 period, which was approved in December 2025, resulting in an increase in the major maintenance provision liability. The outstanding balance of the maintenance provision as of December 31, 2025, was Ps. 2,673 million.

The airport concession tax increased 8.0% to Ps.286.3 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 fourth quarter of 2025, the 4% excess of Concession Tax levied on aeronautical revenues amounted to Ps.110 million, equivalent to 3.2% of the sum of OMA’s aeronautical and non-aeronautical revenues. This amount is included within the Ps.286.3 million recorded as Concession Tax expense in 4Q25. 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, were added to the reference value used in the joint maximum tariff revision for the 2026 – 2030 period. 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.62.4 million, 3.4% lower, as a result of the decrease in EBITDA during the quarter.

Total operating costs and expenses increased 3.2%.

Operating Income and Adjusted EBITDA

Operating Income was Ps.2,131 million, 2.9% lower than 4Q24, with an operating margin of 51.8%.

Adjusted EBITDA was Ps.2,577 million, 5.9% higher than 4Q24, with a margin of 73.6%.

*Excluding the incremental effect of the concession tax on aeronautical revenues, OMA’s Adjusted EBITDA would have been Ps.2,684 million, with a margin of 76.7% during 4Q25. For the full year 2025, Adjusted EBITDA would have been Ps.10,585 million, with a margin of 77.5%.

Financing Expense and Net Income

Financing Expense was Ps.290 million compared to Ps.332 million in 4Q24. The decrease is mainly due to lower changes in the present value of the major maintenance provision, as well as a higher interest income during the quarter.

Consolidated net income in the quarter was Ps.1,223 million, an increase of 3.6% as compared to 4Q24.

Earnings per share, based on net income of the controlling interest was Ps.3.15, and earnings per ADS was US$1.40. Each ADS represents eight Series B shares.

MDP and Strategic Investments

In 4Q25, capital investments and major maintenance works in the MDPs and strategic investments totaled Ps.755 million, comprised of Ps.613 million in improvements to concessioned assets, Ps.81 million in major maintenance and Ps.61 million in strategic investments.

The most important investment expenditures included:

Indebtedness

Derivatives

As of the date of this report, OMA has no financial derivatives exposure.

Cash Flow Statement

During 4Q25, cash flows from operating activities generated cash of Ps.1,851 million.

In the fourth quarter of 2025, investing activities used cash for Ps.663 million. Financing activities mainly reflect the payment of the second installment of the dividend approved at the Annual General Ordinary Shareholders’ Meeting held on April 25, 2025, resulting in a net cash outflow of Ps.2,535 million during the quarter.

The net increase in cash resulting from operating, investing and financing activities in 4Q25 was Ps.1,347 million. This, combined with the negative effect of changes in the value of cash of Ps.0.3 million, resulted in a Cash and Cash Equivalents balance as of December 31, 2025, of Ps.3,098 million.

Relevant Events

Approval of Master Development Program (MDP) for the 2026 - 2030 period. On December 18, 2025, OMA announced that it received approval from the Ministry of Infrastructure, Communications and Transportation (SICT), through the Federal Civil Aviation Agency (AFAC), of the Master Development Program for each of its thirteen concessionaires corresponding to the 2026–2030 period. The total committed investment amounts were Ps. 16,005 million, expressed in pesos as of December 31, 2024.

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.20.7862 as of December 31, 2024, and Ps.18.0012 as of December 31, 2025.

Construction revenue, 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.

Capital investments: 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.

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

Passengers and 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.

Adjusted EBITDA 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.
