The number of seats offered increased 410% as compared to 2Q20 and decreased 23.6% as compared to the second quarter of 2019, mainly due to the number of routes suspended by the airlines.

OMA Carga’s revenues increased by 69.3%, as compared to 2Q20 due to higher handling, storage and custody activity related to air import cargo during the quarter. Total tonnage handled was of 9,667 metric tons, 102.2% higher than 2Q20.

OMA VYNMSA Aero Industrial Park: Revenues reached Ps.15 million, representing an increase of 25.6% versus 2Q20. The increase is due to additional revenues generated from three warehouses rented during 2020. which started generating revenues since 4Q20.

Commercial revenues increased 87.8%. The line items with the largest variations were:

Restaurants, Car Rentals and Retail, +104%, +63.2% and +51.2%, respectively, as a result of lower levels of discounts granted, as well as an increase in revenues from revenue shares.

Diversification revenues increased 114%, mainly due to higher revenues from hotel services and 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.

The sum of cost of airport services and general and administrative expenses (G&A) increased 6.9%, mainly due to higher contracted services costs and an increase to minor maintenance cost, as a result of passenger traffic growth during the quarter.

The major maintenance provision was Ps.151 million, and reflects a higher level of future executions of major maintenance works, pursuant to the Master Development Program for the period 2021-2025. The outstanding balance of the maintenance provision as of June 30, 2021 was Ps.1,553 million.

The airport concession tax was Ps.81 million and the technical assistance fee was Ps.34 million.

Unless stated otherwise, all comparisons of operating or financial results are made with respect to the comparable prior of 2020. The exchange rates used to convert foreign currency amounts were Ps.19.1685 as of June 30, 2019, Ps. 23.1325 as of June 30, 2020, Ps. 19.9352 as of December 31, 2020, and Ps.19.8157 as of June 30, 2021.

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.

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.
