Consolidated Revenues

Consolidated Revenues for 3Q23 increased 0.7% YoY, or Ps.44.0 million, to Ps.6,338.8 million, mainly due to the following increases:

• 3.9% in revenues from aeronautical services to Ps.3,790.7 million. Mexico contributed Ps.2,783.1 million, while Puerto Rico and Colombia accounted for Ps.499.4 million and Ps.508.2 million, respectively; and

• 2.4% in revenues from non-aeronautical services to Ps.2,242.5 million. Mexico contributed Ps.1,630.8 million, while Puerto Rico and Colombia accounted for Ps.443.7 million and Ps.168.0 million, respectively.

These increases were partially offset by a 33.1%, or Ps.151.5 million, YoY decline in construction services revenues to Ps.305.6 million, principally in Mexico.

Excluding revenues from construction services, for which there is an equivalent expense recorded under IFRS accounting standards, total revenues would have increased 3.3% YoY, to Ps.6,033.2 million.

Excluding revenues from construction services, Mexico represented 73.2% of ASUR´s total revenues in 3Q23, while Puerto Rico and Colombia represented 15.6% and 11.2%, respectively.

Commercial Revenues in 3Q23 increased 3.2% YoY to Ps.2,077.3 million, mainly reflecting the 3.2% increase in passenger traffic (including transit and general aviation passengers). Commercial revenues increased 2.4% to Ps.1,468.0 million in Mexico and 7.7% to Ps.441.3 million in Puerto Rico, and were partly offset by a 1.0% decline to Ps.167.9 million in Colombia.

Commercial Revenues per Passenger remained flat YoY at Ps.116.5 in 3Q23.

ASUR 3Q23 Page 3 of 24

Consolidated Operating Costs and Expenses

Consolidated Operating Costs and Expenses, including construction costs, increased 2.4% YoY, or Ps.61.3 million, to Ps.2,660.3 million in 3Q23.

Excluding construction costs, operating costs and expenses increased 9.9% YoY, or Ps.212.8 million, reflecting the following factors:

• Mexico: increased 9.8%, or Ps.124.4 million, mainly reflecting higher costs in connection to personnel, technical assistance, energy, concession fees, security, maintenance, materials and supplies, professional fees, together with higher cost of sales from directly operated stores.

• Puerto Rico: increased 24.0%, or Ps.116.3 million reflecting difficult comps primarily due to the recovery of expenses under the American Rescue Plan Act for an amount of Ps.175.7 million in 3Q23, partially offset by the FX conversion impact resulting from the appreciation of the Mexican peso against the US dollar.

• Colombia: declined 7.2%, or Ps.27.8 million, mainly reflecting the FX conversion effect from the depreciation of the Colombian peso against the Mexican peso, partially offset by increases in personnel and security and maintenance expenses.

Cost of Services increased 19.5%, or Ps.196.6 million, mainly reflecting YoY increases in personnel costs, surveillance and cleaning services, maintenance and conservation, energy. Higher cost of revenues from concession stores operated directly by ASUR together with a more difficult comps from the Ps.175.7 million recovery in expenses in 3Q22 in connection with the application of the American Rescue Plan Act also contributed to the YoY increase in costs of services. This was partially offset by the foreign exchange conversion impact resulting from the appreciation of the Mexican peso against the US dollar together with the depreciation of the Mexican peso against the Colombian peso.

Construction Costs declined 33.1% YoY, or Ps.151.5 million. This was mainly driven by a YoY decline of 53.6%, or Ps.213.4 million in construction costs in Mexico, which offset the 106.0% or Ps.61 million increases in Puerto Rico and 59.7%, Ps.0.9 million in Colombia.

Administrative Expenses that reflect administrative costs in Mexico increased 13.0% YoY.

Consolidated Technical Assistance increased by 4.3% YoY mainly.

Concession Fees increased 0.7% YoY, principally reflecting a 6.2% increase in Mexico due to higher regulated revenues which is a factor in the calculation of the concession fee. This was partially offset by declines of 6.4% and 1.3% in Colombia and Puerto Rico, respectively reflecting lower revenues in these two countries.

Depreciation and Amortization declined 0.6% YoY, or Ps.2.9 million, principally due to decreases of 8.5%, or Ps.8.9 million in Colombia and 11.7%, or Ps.21.3 million in Puerto Rico, partially offset by an increase of 11.6% or Ps.27.3 million in Mexico.

Consolidated Operating Profit and EBITDA

ASUR reported a Consolidated Operating Profit of Ps.3,678.5 million in 3Q23 representing an operating margin of 58.0%, compared to Ps.3,696.1 million in 3Q22 and an operating margin of 58.7%.

Adjusted Operating Margin, which excludes the effect of IFRIC 12 with respect to the construction of or improvements to concessioned assets in Mexico, Colombia and Puerto Rico was 61.0% in 3Q23 compared to 63.3% in 3Q22. Adjusted operating margin is calculated as operating profit or loss divided by total revenues less construction services revenues.

EBITDA increased 3.2%, or Ps.131.4 million, to Ps.4,198.4 million in 3Q23, from Ps.4,067.0 million in 3Q22. By country of operations, EBITDA increased YoY by 4.4% or Ps.138.3 million to Ps.3,286.6 million in Mexico, and by 7.9%, or Ps.36.9 million, to Ps.503.6 million in Puerto Rico. In Colombia, EBITDA declined by 9.6%, or Ps.43.9 million, to Ps.411.3 million. Consolidated EBITDA margin in 3Q23 was 66.2% up from 64.6% in 3Q22.

Adjusted EBITDA Margin, which excludes the effect of IFRIC 12 with respect to the construction of or improvements to concessioned assets in Mexico, Puerto Rico, and Colombia, was 69.6% in 3Q23, compared to 69.7% in 3Q22.

In 3Q23 ASUR reported a Ps.143.0 million Consolidated Comprehensive Financing Gain, compared to a Ps.185.2 million loss in 3Q22.

During 3Q23 ASUR reported a foreign exchange gain of Ps.126.7 million, resulting from the 1.6% quarter-end depreciation of the Mexican peso against the U.S. dollar (0.5% average appreciation) during the period, together with a U.S. dollar net asset position. This compares to a Ps.3.5 million foreign exchange gain in 3Q22 resulting from the 0.2% quarter-end appreciation of the Mexican peso (0.5% average depreciation) on a U.S. dollar net asset position.

Interest expense declined Ps.18.9 million, or 6.4% YoY, mainly reflecting FX conversion in Puerto Rico.

Interest income increased 171.3%, or Ps.186.1 million YoY, reflecting a higher cash balance position.

Income Taxes

Income Taxes for 3Q23 increased Ps.175.6 million YoY, principally due to the following increasesariations:

• Ps.125.3 million in income taxes, reflecting mainly a higher taxable income base in Mexico.

• Ps.50.3 million in deferred income taxes, mainly in Mexico resulting from an increase in the taxable base due to a decline in inflation to 1.5% in 3Q23 from of 2.3% in 2Q22.

Majority Net Income

ASUR reported Majority Net Income of Ps.2,709.5 million in 3Q23, compared to Ps.2,546.5 million in 3Q22. This resulted in earnings per common share in 2Q23 of Ps.9.0318, or earnings per ADS of US$5.1869 (one ADS represents ten series B common shares). This compares to earnings per share of Ps.8.4883, or earnings per ADS of US$4.8748 for 3Q22.

Net Income

ASUR reported Net Income of Ps.2,807.1 million in 3Q23, increasing 4.8%, or Ps.128.8 million, from Ps.2,678.4 million in 3Q22.

ASUR’s Mexico operations reported a Ps.200.8 million Comprehensive Financing Gain in 3Q23, compared to a Ps.55.0 million loss in 3Q22. This was mainly due to a foreign exchange gain of Ps.125.5 million in 3Q23 resulting from the 1.6% quarter-end depreciation of the Mexican peso (0.5% average appreciation) against the U.S. dollar on a foreign currency net asset position. This compares to a Ps.4.1 million foreign exchange gain in 3Q22, resulting from the 0.2% quarter-end appreciation of the Mexican peso during that period (0.5% average depreciation) against the U.S. dollar on a foreign currency net asset position.

Interest expenses declined 6.4% YoY, or Ps.8.0 million while interest income increased 192.6% YoY or Ps.126.4 million, resulting from a higher cash balance.

Puerto Rico Revenues

Total Puerto Rico Revenues increased 6.0% YoY to Ps.1,061.7 million in 3Q23.

Excluding construction services, revenues declined by 0.1%, mainly due to the following YoY variations:

• A 6.0% decline in revenues from aeronautical services, and

• A 7.5% increase in revenues from non-aeronautical services.

Commercial Revenues per Passenger were Ps.139.2 in 3Q23, compared to Ps.161.3 in 3Q22.

Four commercial spaces were opened at Luis Muñoz Marin (LMM) Airport over the last 12 months, as shown in Table 20. More details can be found on page 20 of this report.

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

Total Operating Costs and Expenses in Puerto Rico increased 32.7% YoY to Ps.718.9 million in 3Q23. Construction costs in the quarter increased 106.0% to Ps.118.6 million from Ps.57.6 million in 3Q22.

Excluding construction costs, operating costs and expenses increased 24.0% YoY, or Ps.116.3 million principally reflecting a recovery of expenses for a total of Ps.175.7 million in 3Q22 in connection with the American Rescue Plan Act, partially offset by the appreciation of the Mexican peso against the U.S. dollar in the period.

Cost of Services increased 53.9% or Ps.138.2 million in 3Q23, mainly reflecting a Ps.175.7 expense recovery in 3Q22 in connection with the American Rescue Plan Act. This was partially offset by the appreciation of the Mexican peso against the US dollar.

Concession Fees paid to the Puerto Rican government declined 1.3% YoY, or Ps.0.6 million in 3Q23, consistent with the terms agreed under the concession agreement.

Depreciation and Amortization decreased 11.7% YoY, or Ps.21.3 million, principally reflecting the foreign exchange translation impact as the quarter-end and average Mexican peso exchange rate fluctuated from Ps.17.4127 and Ps.17.0572 per U.S. dollar in 3Q22, to Ps.20.0925 and Ps.20.2334 per U.S. dollar, respectively in 3Q23.

During 3Q23, Puerto Rico reported a Ps.90.1 million Comprehensive Financing Loss, compared to a Ps.121.3 million loss in 3Q22, principally due to interest accrued from the US$200.0 million bond issuance in July 2022.

On March 22, 2013, Aerostar carried out a private bond placement for a total of US$350.0 million to finance a portion of the Concession Agreement payment to the Puerto Rico Ports Authority, and certain other costs and expenditures associated with it. On June 24, 2015, Aerostar carried out a private bond placement for a total of US$50.0 million.

In December 2020, Aerostar entered into a three-year revolving line of credit with Banco Popular de Puerto Rico for the amount of US$20.0 million. Funds have not yet been withdrawn.

In May 2022, Aerostar renegotiated the terms of its US$50.0 million principal amount of 6.75% senior secured notes extending the maturity to March 22, 2035.

In July 2022, Aerostar in Puerto Rico issued US$200.0 million principal amount of 4.92% senior secured notes due March 22, 2035. All long-term debt is collateralized by Aerostar’s assets.

EBITDA increased 7.9% to Ps.503.6 million in 3Q23 from Ps.466.6 million in 3Q22. EBITDA Margin, in turn, increased to 47.4% in 3Q23 from 46.6% in 3Q22.

Adjusted EBITDA Margin (which excludes IFRIC 12) increased to 53.4% in 3Q23, from 49.4% in 3Q22.

Puerto Rico Capital Expenditures

During 3Q23, Aerostar made capital expenditures of Ps.129.6 million, compared to investments of Ps.64.0 million in 2Q22. Capital expenditures for the nine-months ended September 30, 2023 amounted to Ps.267.3 million compared to Ps.228.6 million for the same period in 2022.

Puerto Rico Tariff Regulation

The Airport Use Agreement entered into by and among Aerostar, the airlines serving LMM Airport, and the Puerto Rico Ports Authority governs the relationship between Aerostar and the principal airlines serving LMM Airport. The agreement entitles Aerostar to an annual contribution from the airlines of US$62.0 million during the first five years of the term. From year six onwards, the total annual contribution for the prior year increases in accordance with an adjusted consumer price index factor based on the U.S. non-core consumer price index. The annual fee is divided between the airlines that operate at LMM Airport in accordance with the regulations and structure defined under the Airport Use Agreement to establish the contribution of each airline for each particular year.

Total Operating Costs and Expenses in Colombia declined 6.9% YoY to Ps.363.1 million. Excluding construction costs, operating costs and expenses declined 7.2% YoY to Ps.360.8 million. This decrease was mainly driven by the foreign exchange conversion of the Colombian peso with respect to the Mexican peso, partially offset by increases in personnel costs, security and cleaning expenses.

Cost of Services declined 6.9% YoY, or Ps.10.2 million.

Construction Costs increased 59.7% YoY, or Ps.0.9 million due to investments in furniture and equipment.

Concession Fees, which include fees paid to the Colombian government, declined 6.4% YoY, mainly reflecting the decrease in regulated and non-regulated revenues during the period.

Depreciation and Amortization declined 8.5%.

In 3Q23, ASUR's operations in Colombia reported an Operating Profit of Ps.315.4 million, compared to Ps.326.7 million in 3Q22. Operating margin was 46.5% in 3Q23 compared to an operating margin of 45.6% in 3Q22. Adjusted operating margin, which excludes the effect of IFRIC12 with respect to construction or improvements to concessioned assets, was 46.6% in 3Q23 compared to an adjusted operating margin of 45.7% in 3Q22.

EBITDA in 3Q23 was Ps.411.3 million resulting in an EBITDA margin of 60.6%. This compares to an EBITDA of Ps.455.2 million and an EBITDA margin of 63.5% in 3Q22.

The Adjusted EBITDA Margin, which excludes the effect of IFRIC12 with respect to the construction or improvements of the concessioned assets, was 60.8% in 3Q23, compared to an adjusted EBITDA margin of 63.6% in 3Q22, mainly reflecting the impact in passenger traffic and bad debt provisions resulting from the suspension of two local airlines in Colombia in 1Q23.

Colombia Capital Expenditures

During 3Q23, Airplan made capital investments of Ps.2.1 million compared to Ps.1.4 million in 3Q22. Accumulated capital investments for 9M23 amounted to Ps.8.8 million compared to Ps.3.1 million in 9M22.

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 that are generated by the 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. Airplan's regulated revenues amounted to Ps.508.2 million in 3Q23.

ASUR 3Q23 Page 16 of 24

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 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 or as an alternative to cash flow 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 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 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 or as an alternative to cash flow as an indicator of liquidity and is not defined under U.S. GAAP or IFRS and may be calculated differently by different companies.
