Freight Logistics Services

OMA Carga’s revenues increased by 18.0%, as compared to 4Q23, due to an increase in revenues from the ground cargo operations in Monterrey.

Hotel Services

The NH Collection Terminal 2 Hotel had an 84.4% occupancy rate, compared to 92.4% in 4Q23, with a 27.8% increase in the average room rate to Ps.3,447 per night.

Industrial Services

OMA VYNMSA Aero Industrial Park: Revenues reached Ps.47.3 million, an increase of 130.8% versus 4Q23. The increase is mainly explained by a higher number of square meters leased as compared to 4Q23.

Consolidated Financial Results

Revenues

Aeronautical revenues increased 11.1%.

Non-aeronautical revenues increased 21.7%.

Commercial revenues increased 19.1%. The line items with the largest increases were:

Restaurants, +29.4%, as a result of the opening or replacement of outlets throughout the year (8 outlets in the quarter), with higher variable rents.

VIP Lounges, +58.7%, as a result of an increase in rates and a higher number of users. In November 2024, a new lounge began operations at the Durango airport.

Retail, +29.4%, mainly as a result of the contribution of new spaces opened or replacements in existing spaces in previous quarters and the opening or replacement of 19 outlets in the quarter.

Diversification revenues increased 28.0%, mainly due to higher revenues from Industrial Services and Hotel Services.

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 14.9% as compared to 4Q23.

The major maintenance provision expense was Ps.39 million. The outstanding balance of the maintenance provision as of December 31, 2024 was Ps.2,284 million.

The airport concession tax increased 97% to Ps.265.2 million, as a result of the change in the rate from 5% to 9% applied to the revenues generated by OMA’s airport concessions, pursuant to the Mexican Federal Duties Law. 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.

In the fourth quarter of 2024, the 4% excess of Concession Tax levied on aeronautical revenues amounted to Ps.101.7 million, equivalent to 3.1% of the sum of OMA's aeronautical and non-aeronautical revenues. This amount is included within the Ps.265.2 million recorded as Concession Tax expense in 4Q24. Excluding the Ps.101.7 million and its effects on OMA's results, Adjusted EBITDA for OMA would have been Ps.2,532 million, with a margin of 76.7%.

The technical assistance fee was Ps.64.6 million.

Total operating costs and expenses increased 11.7%.

Operating Income and Adjusted EBITDA

Operating Income was Ps.2,193 million, with an operating margin of 53.3%.

Adjusted EBITDA was Ps.2,433 million, with a margin of 73.8%.

*Excluding the incremental effect of the concession tax on aeronautical revenues, OMA's Adjusted EBITDA would have been Ps.2,532 million, with a margin of 76.7% during 4Q24. For the twelve months ended on December 31, 2024, Adjusted EBITDA would have been Ps.9,440 million, with a margin of 77.3%

Financing Expense and Net Income

Financing Expense grew 48.1% as compared to 4Q23. The increase is primarily due to a higher interest expense resulting from a change in the present value of major maintenance provision as a result of a decrease in the discount rates used for its calculation. This cost does not impact the cash flow.

Consolidated net income in the quarter was Ps.1,181 million, a decrease of 5.9% as compared to 4Q23.

Earnings per share, based on net income of the controlling interest was Ps.3.07, and earnings per ADS was US$1.18. Each ADS represents eight Series B shares.

MDP and Strategic Investments

In 4Q24, capital investments and major maintenance works in the MDPs and strategic investments totaled Ps.951 million, comprised of Ps.816 million in improvements to concessioned assets, Ps.63 million in major maintenance, Ps.68 million in strategic investments and Ps.4 million in other concepts.

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 4Q24, cash flows from operating activities generated cash of Ps.1,870 million.

Investing activities used cash for Ps.846 million in the fourth quarter. Financing activities reflect mainly the second installment of the ordinary dividend for Ps.2,125 million, resulting in a net cash outflow of Ps.1,784 million in the quarter.

The net reduction in cash resulting from operating, investing and financing activities in 4Q24 was Ps.761 million. This, combined with the positive effect of changes in the value of cash of Ps.20 million, resulted in a Cash and Cash Equivalents balance as of December 31, 2024 of Ps.1,656 million.

Relevant Events.

OMA obtains Ps.600 million in short-term financing. In November 2024, OMA obtained short-term loans for an aggregate amount of Ps.600 million with three banks. Proceeds were used to support working capital needs and strengthen the company’s liquidity position. Loans mature until May 2025 and carry an annual weighted average interest rate of TIIE 28 + 60 basis points. Through these financings, OMA continues to maintain a solid capital structure. From the previously mentioned amount, on February 12, 2025, OMA made a payment of Ps.150 million of the short-term loan contracted.

OMA's 13 airports achieve Level 3 "Optimization" Accreditation from the Airport Carbon Accreditation (ACA) Program. On February 13, 2025, the Company reports that its 13 airports achieved Level 3 accreditation under the Airport Carbon Accreditation (ACA) program. The carbon footprint accreditation program, led by Airports Council International (ACI), aims to reduce the carbon footprint in the airport industry.

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 2023. The exchange rates used to convert foreign currency amounts were Ps.16.9190 as of December 31, 2023, and Ps.20.7862 as of December 31, 2024.

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.
