·	Puerto<br> Rico: declined 0.4%, or Ps.2.3 million, mainly due to a 6.9% YoY decline in depreciation<br> and amortization resulting from the foreign exchange translation impact and the reversal<br> of provisions associated with employee benefits, partially offset by increases in concession<br> fees, professional fees and materials and supplies.
---	---
·	Colombia:<br> increased 16.6%, or Ps.55.1 million, mainly due to increases in maintenance and conservation,<br> personnel costs, taxes and duties, security and cleaning services, insurance and bonds, energy<br> costs and concession fees.

In 1Q24 ASUR reported a Ps.42.0 million Consolidated Comprehensive Financing Loss, compared to a Ps.527.8 million loss in 1Q23. This variation is mainly attributed to an increase of 54.6%, or Ps.144.7 million in interest income reflecting a higher cash balance position, combined with a 16.5% decline, or Ps.50.6 million in interest expenses resulting from principal payments in Mexico and Puerto Rico.

During 1Q24 ASUR reported a foreign exchange loss of Ps.196.4 million, resulting from the 2.3% quarter-end appreciation of the Mexican peso against the U.S. dollar on a U.S. dollar net asset position (0.3% average depreciation) during the covered period. This compared to a Ps.486.9 million foreign exchange loss in 1Q23 resulting from the 7.3% quarter-end appreciation of the Mexican peso against the U.S. dollar on a U.S. dollar net asset position (4.1% average appreciation) during the covered period.

IncomeTaxes

IncomeTaxes for 1Q24 increased Ps.464.2 million YoY, principally due to the following variations:

·	A<br> Ps.318.8 million increase in income taxes, mainly due to a higher taxable income base in<br> Mexico.
·	A<br> Ps.145.4 million increase in deferred income taxes, mainly in Mexico, resulting from the<br> initial recognition of deferred income tax on untaxed accumulated profits from investments<br> in Puerto Rico and Colombia.

In July 2022, Aerostar in Puerto Rico issued US$200 million principal amount of 4.92% senior secured notes due March 22, 2035. In May 2022, Aerostar renegotiated the terms of its US$50 million principal amount of 6.75% senior secured notes originally due on June 24, 2015, and extended their maturity through March 22, 2035. All long-term debt is collateralized by Aerostar’s assets.

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 March 31, 2024, no such credit line has been drawn.

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.

LTM Net Debt-to-LTM EBITDA stood at negative 0.3x at the close of 1Q24, while the Interest Coverage Ratio was 10.9x. This compared with LTM Net Debt-to-LTM EBITDA of negative 0.1x and an Interest Coverage Ratio of 11.7x as of March 31, 2023, respectively.

AccountsReceivables

Accounts receivables increased 14.8% YoY in 1Q24, mainly driven by increased activity in Mexico and the suspension of operations of Viva Colombia and Ultra Air in Colombia on February 28 and March 29, 2023. During 2023, these two companies accounted for 5.5% and 2.2% of passenger traffic in Colombia, respectively. At the end of 1Q24, these two companies owed ASUR Ps.14.1 million and Ps.9.9 million, respectively.

The 85.2% decline in accounts receivables in Puerto Rico mainly driven by the collection in May 2023 of other income of Ps.300.4 million derived from a judgment in favor of Puerto Rico for the right to charge a charge for each gallon of aviation fuel that was dispatched at the airport for the period from 2013 to 2021, compliant with IFRS IAS 37 and USGAAP ASC-450-30-25-1.

Depreciationand Amortization declined 6.9% YoY, or Ps.11.7 million, principally reflecting the foreign exchange translation impact.

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.

ASUR's Colombian operations reported an Operating Profit of Ps.364.4 million in 1Q24, compared to Ps.325.3 million in 1Q23. Operating margin was 48.3% in 1Q24, compared to 49.0% in 1Q23. The Adjusted operating margin, which excludes the effect of IFRIC12 with respect to construction or improvements to concessioned assets, was 48.5% in 1Q24 compared to an adjusted operating margin of 49.5% in 1Q23.

EBITDAin 1Q24 was Ps.461.0 million, resulting in an EBITDA margin of 61.0%. This compared to an EBITDA of Ps.416.1 million and an EBITDA margin of 62.7% in 1Q23.

The Adjusted EBITDA Margin, which excludes the effect of IFRIC12 with respect to the construction or improvements of the concessioned assets, was 61.3% in 1Q24, compared to an adjusted EBITDA margin of 63.3% in 1Q23, principally due to the decline in passenger traffic and bad debt provisions resulting from the suspension of two local airlines in Colombia in 1Q23.

ColombiaCapital Expenditures

In 1Q24, Airplan made capital investments for a total of Ps.3.9 million, compared to Ps.6.0 million in 1Q23.

ColombiaTariff 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.

During 1Q24, Airplan's regulated revenues amounted to Ps.555.5 million.

Definitions

ConcessionServices 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.

MajorityNet 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.

EBITDAmeans 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.

AdjustedEBITDA 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

ASUR 1Q24 Page 18 of 25

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