Excluding construction costs, operating costs and expenses increased 18.3%, or Ps.430.7 million, due to the following factors:

· Puerto Rico: increased 20.4%, or Ps.122.3 million, mainly due to a foreign exchange gain related to the Mexican peso depreciation against the US dollar and the increase in personnel costs, electricity, insurance and surety bonds, licenses, security and cleaning services, concession fees and depreciation and amortization.

· Colombia: increased 28.2%, or Ps.101.7 million, mainly due to increases in maintenance and conservation, personnel costs, taxes and duties, security and cleaning services, insurance and surety bonds, concession fees, energy costs and depreciation and amortization, and professional fees.

In 3Q24 ASUR reported a Ps.906.5 million Consolidated Comprehensive Financing Gain, compared to a Ps.143.0 million gain in 3Q23. This variation is mainly attributed to a foreign exchange gain of Ps.653.7 million in 3Q24 compared to a foreign exchange gain of Ps.126.7 million in 3Q23.

The foreign exchange gain in 3Q24 resulted from the 7.6% quarter-end depreciation of the Mexican peso against the U.S. dollar on a U.S. dollar net asset position (3.7% average depreciation) during the covered period. The foreign exchange gain in 3Q23 resulted from the 1.6% quarter-end depreciation of the Mexican peso against the U.S. dollar on a U.S. dollar net asset position (0.5% average appreciation) during the covered period.

Interest income increased 63.9%, or Ps.188.4 million reflecting a higher cash balance position, while interest expenses declined 17.3%, or Ps.48.1 million resulting from principal payments made in connection to indebtedness incurred in Mexico and Puerto Rico, and the Ps.10.3 million the amortization of the bank facility in Colombia.

Income Taxes

Income Taxes for 3Q24 increased Ps.520.0 million YoY, principally due to the following variations:

· A Ps.398.7 million increase in income taxes, mainly due to a higher taxable income base in Mexico and Colombia.

· A Ps.121.2 million increase in deferred income taxes, mainly in Mexico, resulting from the initial recognition of deferred income tax on untaxed accumulated profits from investments in Puerto Rico and Colombia.

Net Majority Income

During 3Q24, ASUR reported a Net Majority Income of Ps.3,381.2 million, an increase from the Ps.2,709.5 million net majority income in 3Q23. This resulted in earnings per common share in 3Q24 of Ps.11.2706, or earnings per ADS of US$ 5.7374 (one ADS represents ten (10) series B common shares), compared to earnings per share of Ps.9.0318, or earnings per ADS of US$4.5977 in 3Q23.

Net Income

On November 15, 2023, Aerostar renewed the US$20.0 million revolving credit facility with Banco Popular de Puerto Rico, with a maturity date of December 29, 2026. As of June 30, 2024, no credit line has been drawn under this facility.

In April 2023, Banco Popular transferred to the Bank of Bogotá its interests under the syndicated loan entered into with Airplan by issuing promissory notes under the same terms and conditions than the original loan.

In July 2024, ASUR restructured its line of credit with BBVA Mexico so that the principal amount owed under this facility be paid on the maturity date on July 11, 2029. The annual interest rate is equivalent to the 28-day TIIE rate plus an applicable margin of 1.35 points.

LTM Net Debt-to-LTM EBITDA stood at negative 0.3x as of September 30, 2024, while the Interest Coverage Ratio was 12.1x. This compared to LTM Net Debt-to-LTM EBITDA of negative 0.3x and an Interest Coverage Ratio of 11.4x as of September 30, 2023, respectively.

Mexico Revenues

Mexico Revenues increased 17.1% YoY to Ps.5,386.4 million, mainly reflecting the new terms of the Master Development Plan published on December 13, 2023, and effectively starting on January 1, 2024.

Excluding construction, revenues increased 11.8% YoY, mainly due to increases of 19.3% in revenues from aeronautical services and 0.9% in revenues from non-aeronautical services.

Commercial Revenues decreased by 1.7% YoY, as shown in Table 12, mainly due to the 10.4% decline in passenger traffic.

Commercial Revenues per Passenger for 3Q24 increased to Ps.149.0 from Ps.135.9 in 3Q23.

ASUR classifies commercial revenues as those derived from the following activities: duty-free stores, car rentals, retail operations, banking and currency exchange services, advertising, teleservices, non-permanent ground transportation, food and beverage operations, parking lot fees, and other.

As shown in Table 14, during the last 12 months, ASUR opened 18 new commercial spaces, 8 at Merida, 2 each at Huatulco, Tapachula, and Veracruz airports, and 1 each at Oaxaca, Cozumel, Minatitlan, and Villahermosa airports. More details of these openings can be found on page 20 of this report.

Total Mexico Operating Costs and Expenses increased 29.9% YoY, or Ps.471.9 million. Excluding construction costs, operating costs and expenses increased 14.8%, or Ps.206.6 million, mainly due to higher concession fees, personnel expenses, professional fees, insurance and surety bond expenses, surveillance and cleaning services, and maintenance and conservation costs.

Cost of Services increased 7.7% YoY, primarily due to higher costs in connection with personnel, surveillance insurance and surety bond expenses, professional fees, surveillance and cleaning services, maintenance, and conservation

Administrative Expenses declined 22.2% YoY.

The Technical Assistance fee declined 46.1% YoY, principally due to the reduction in the technical assistance fees charged by ITA to 2.5% from 5.0% of the EBITDA generated by ASUR´s Mexican operations starting January 1, 2024.

Concession Fees, which include fees paid to the Mexican government, increased by 108.7% YoY, principally due to the increase in the concession fee rate to 9% from 5% starting January 1, 2024 and the increase in the tariff calculation base set forth in the Mexican concession titles.

Depreciation and Amortization increased 13.1% YoY, due to the recognition of investments made to date.

During 3Q24, ASUR’s Mexico operations reported a Ps.947.2 million Comprehensive Financing Gain, compared to a Ps.200.8 million in 3Q23. This was mainly due to a Ps.654.0 million foreign exchange gain reported in 3Q24, resulting from the 7.6% quarter-end depreciation of the Mexican peso against the U.S. dollar on a foreign currency net asset position (3.7% average depreciation). This compared to a Ps.125.5 million foreign exchange gain in 3Q23, resulting from the 1.6% quarter-end depreciation of the Mexican peso during that period against the U.S. dollar on a foreign currency net asset position (0.5% average appreciation).

Interest income increased 97.6% YoY, or Ps.187.4 million, mainly resulting from a higher cash balance, while interest expenses declined 26.1%, or Ps.30.5 million YoY mainly due to principal payments in 2023 and 1H24.

3 Adjusted EBITDA Margin excludes the effect of IFRIC12 with respect to the construction or improvements to concessioned assets, and is calculated by dividing EBITDA by total revenues less construction services revenues.

Mexico reported an Operating Gain of Ps.3,336.1 million and an Operating Margin of 61.9% in 3Q24. This compared to an Operating Gain of Ps.3,020.3 million and an Operating Margin of 65.7% in 3Q23.

Adjusted Operating Margin for 3Q24 was 67.6% compared with 68.4% in 3Q23. Adjusted Operating Margin excludes the effect of IFRIC 12 with respect to the construction of or improvements to concessioned assets and is calculated as operating profit divided by total revenues excluding construction services revenues.

EBITDA increased 10.7%, or Ps.351.9 million, to Ps.3,635.4 million in 3Q24, from Ps.3,283.6 million in 3Q23. EBITDA margin in 3Q24 was 67.5% compared to 71.4% in 3Q23.

Adjusted EBITDA Margin, which excludes the effect of IFRIC 12 with respect to the construction of or improvements to concessioned assets, was 73.6% in 3Q24, compared to 74.4% in 3Q23.

Mexico Tariff Regulation

Colombia Tariff Regulation

Functions of the Special Administrative Unit of Civil Aeronautics include establishing and collecting fees, tariffs, and rights for the provision of aeronautical and airport services or those generated by concessions, authorizations, licenses, or any other type of income or property. As a result, Resolution 04530, issued on September 21, 2007, establishes tariffs for the rights and the rates conceded to the concessionaire of the following airports: José María Córdova of Rionegro, Enrique Olaya Herrera of Medellín, Los Garzones of Montería, El Caraño of Quibdó, Antonio Roldán Betancourt of Carepa, and Las Brujas of Corozal. This resolution also established the methodology to update and the mechanisms to collect such fees, tariffs, and rights.

Definitions

Concession Services Agreements (IFRIC 12 interpretation). In Mexico and Puerto Rico, ASUR is required by IFRIC 12 to include in its income statement an income line, “Construction Revenues,” reflecting the revenue from construction of, or improvements to concessioned assets made during the relevant period. The same amount is recognized under the expense line “Construction Costs” because ASUR hires third parties to provide construction services. Because equal amounts of Construction Revenues and Construction Costs have been included in ASUR's income statement as a result of the application of IFRIC 12, the amount of Construction Revenues does not have an impact on EBITDA, but it does have an impact on EBITDA Margin. In Colombia, “Construction Revenues” include the recognition of the revenue to which the concessionaire is entitled for carrying out the infrastructure works in the development of the concession, while “Construction Costs” represents the actual costs incurred in the execution of such additions or improvements to the concessioned assets.

Majority Net Income reflects ASUR’s equity interests in each of its subsidiaries and therefore excludes the 40% interest in Aerostar that is owned by other shareholders. Other than Aerostar, ASUR owns (directly or indirectly) 100% of its subsidiaries.

EBITDA means net income before provision for taxes, deferred taxes, profit sharing, non-ordinary items, participation in the results of associates, comprehensive financing cost, and depreciation and amortization. EBITDA should not be considered as an alternative to net income, as an indicator of our operating performance, as an alternative to cash flow or as an indicator of liquidity. Our management believes that EBITDA provides a useful measure that is widely used by investors and analysts to evaluate our performance and compare it with other companies. EBITDA is not defined under U.S. GAAP or IFRS and may be calculated differently by different companies.

Adjusted EBITDA Margin is calculated by dividing EBITDA by total revenues excluding construction services revenues for Mexico, Puerto Rico, and Colombia and excludes the effect of IFRIC 12 with respect to the construction of, or improvements to concessioned assets. ASUR is required by IFRIC 12 to include in its income statement an income line reflecting the revenue from construction of, or improvements to concessioned assets made during the relevant period. The same amount is recognized under the expense line “Construction Costs” because ASUR hires third parties to provide construction services. In Mexico and Puerto Rico, because equal amounts of Construction Revenues and Construction Costs have been included in ASUR's income statement as a result of the application of IFRIC 12, the amount of Construction Revenues does not have an impact on EBITDA, but it does have an impact on EBITDA Margin, as the increase in revenues that relates to Construction Revenues does not result in a corresponding increase in EBITDA. In Colombia, construction revenues do have an impact on EBITDA, as construction revenues include a reasonable margin over the actual cost of construction. Like EBITDA Margin, Adjusted EBITDA Margin should not be considered as an indicator of our operating performance,
