ASUR 3Q26 Page 4 of 33 Review of Consolidated Results ASUR's consolidated 3Q26 and 9M26 results include the operations of ASUR US Airports , the Company’s U .S. commercial operation, which was acquired in December 2025 and was not part of the consolidated results in 3Q25. Accordingly, YoY comparisons reflect the expanded scope of consolidation, primarily affecting non -aeronautical revenues, operating costs, and margins. On September 1, 2026, ASUR closed the acquisition of CPC Aeroportos, adding to its portfolio 17 airports in Brazil, and one each in Costa Rica, Curazao , and Ecuador (“Brazil & Others”), and starting on that date ASUR began to fully consolidate its operations on a line by line basis. From the acquisition date through September 30, 2026, these operations contributed revenues of Ps.841.2 million and EBITDA of Ps.313.2 million.

This YoY increase driven by the following increases: • 26.9%, or Ps.639.6 million, to Ps.3,014.6 million in Non-aeronautical Services Revenue. This was primarily driven by revenue contributions of Ps.1,347.0 million in Mexico, Ps.532.5 million in Puerto Rico, Ps.456.4 million from the U.S. commercial operations, reflecting its third full quarter of consolidation following its acquisition in December 2025. Brazil & Others contributed Ps.361.9 million following its acquisition on September 1, 2026 and Colombia Ps.316.9 million. • 43.0%, or Ps.778.7 million, to Ps.2,591.1 million , in Construction Services Revenues , primarily reflecting higher construction activity in Mexico. • 5.2%, or Ps.236.8 million, to Ps.4,814.8 million in Aeronautical Services Revenues .

ASUR 3Q26 Page 5 of 33 Revenues Excluding Construction Services, which are recognized in accordance with IFRS and offset by the corresponding construction costs, increased 12.6 % to Ps.7, 829.4 million. Mexico accounted for 57.7% of total revenues excluding construction services, while Puerto Rico, Colombia, the United States and one month of operations in Brazil & Others accounted for 14.6%, 13.2%, 5.8% and 8.6%, respectively. Commercial Revenues increased 22.2% YoY to Ps.2, 703.3 million, primarily reflecting the Ps.41 2.8 million contribution from the U.S., Ps.264.4 million from Brazil & Others resulting from the first month of operations since its acquisition, and a 1 6.4% increase in Colombia to Ps. 316.8 million. These increases were partially offset by decreases of 14.6% in Mexico to Ps.1,178.9 million and 5.2% in Puerto Rico to Ps.530.4 million. Consolidated Operating Costs and Expenses Consolidated Operating Costs and Expenses, including Construction Costs, increased 28.8% YoY, or Ps.1,460.3 million, to Ps.6,530.8 million in 3Q26. Excluding Construction Costs, operating costs and expenses increased 20.9%, or Ps.681.6 million. By region: • Mexico: increased 2.2%, or Ps.37.3 million, primarily reflecting higher salaries and wages, professional fees, security and cleaning services, depreciation and amortization, provisions for doubtful accounts, and maintenance expenses. These increases were partly offset by lower concession fees, electricity costs, technical assistance fees, cost of sales related to ASUR’s directly operated commercial operations, insurance and surety bonds, and tax recoveries and adjustments. • Puerto Rico: decreased 5.6%, or Ps.43.5 million, primarily due to lower concession fees, electricity costs, taxes and fees, maintenance and conservation, insurance and surety bonds, as well as foreign currency translation effects. • Colombia: decreased 7.7%, or Ps.62.5 million, mainly due to the favorable impact of the change in the concession amortization method in 3Q25. This was partially offset by higher personnel costs, security and cleaning services, electricity costs, and maintenance and conservation. • United States: operating costs and expenses totaled Ps.294.1 million, primarily comprised of lease expenses payable to airport authorities, personnel costs, professional fees, and insurance and surety bond costs. These were partially offset by favorable accounting effects related to lease agreements with U.S. airport authorities under IFRS 16. • Brazil & Others: Operating costs totaled Ps.456.1 million, primarily comprising depreciation and amortization, concession fees, salaries and wages, electricity costs, security services, maintenance and conservation, cleaning services, professional fees, insurance and surety bond costs, taxes and fees, and materials and supplies. Cost of Services increased 39.6%, or Ps. 596.9 million, during the quarter, primarily due to higher personnel costs, security and cleaning services, professional fees, insurance and surety bond costs, lease payments to airport authorities, and provisions for doubtful accounts. These increases were partially offset by lower maintenance and electricity costs, as well as the favorable accounting impact of lease agreements with U.S. airport authorities under IFRS 16. Construction Costs increased 43.0%, or Ps.778.7 million, reflecting increases of 32.4%, or Ps.529.1 million, in Mexico, a Ps.164.9 million contribution from Brazil & Others , together with an increase Ps.134.7 million in Colombia. This was partially offset by a 28.1%, or Ps.50.0 million, decrease in Puerto Rico. Administrative Expenses increased 102.8%, or Ps.89.7 million, primarily reflecting a Ps.66.1 million contribution from Brazil & Others. Technical Assistance Fees decreased 31.6%. Consolidated Concession Fees increased 3.3%, primarily reflecting a Ps.35.7 million contribution from Brazil & Others. Depreciation and Amortization increased 0.2%, or Ps.2.0 million. This was primarily due to a 12.2%, or Ps.37.8 million, increase in Mexico; a Ps.93.0 million contribution from Brazil & Others; and a 0.8%, or Ps.1.5 million, increase in Puerto Rico. These increases were partially offset by a 29.9%, or Ps.130.4 million, decrease in Colombia, due to the adjustment to the concession amortization method. Consolidated Operating Profit and EBITDA

Puerto Rico’s EBITDA increased 7.1%, or Ps.40.1 million, to Ps.602.4 million, and Colombia’s increased 1.6%, or Ps.9.0 million, to Ps.590.0 million. These increases were partially offset by a 9.5%, or Ps.331.4 million, decrease in Mexico’s EBITDA to Ps.3,164.7 million. Consolidated EBITDA margin was 45.3% in 3Q26, compared to 52.9% in 3Q25.

This YoY variation was primarily driven by a 112.1% increase in foreign exchange losses to Ps.803.5 million, compared to a loss of Ps.378.7 million in 3Q25. In 3Q26 the Mexican peso depreciated 3.4% against the U.S. dollar at period end and appreciated 1.2 % on average, applied to a lower U.S. dollar-denominated net asset position than in 3Q25. By comparison, in 3Q25 the peso appreciated 2.6% against the U.S. dollar at period end and 1.1% on average, applied to a U.S. dollar-denominated net asset position. Interest expense increased 95.6%, or Ps.426.0 million, primarily due to two loans obtained in Mexico (Ps.6,390.0 million on December 5, 2025, and Ps.22,225.0 million on August 31, 2026). The increase also included Ps.114.4 million related to the measuremen t and subsequent accrual of lease liabilities associated with ASUR’s U.S. operations agreements with U.S. airport authorities. Under IFRS 16, these arrangements are treated as lease liabilities rather than operating expenses, resulting in finance costs being recognized over time. A further Ps.144.5 million related to the addition of Brazil & Others. In 3Q26, ASUR reported a Ps.719.2 million gain on three foreign exchange forward contracts entered into for hedging purposes. Interest income decreased 32.6%, or Ps.115.0 million, due to lower cash balances and yields. Income Taxes Income taxes decreased by Ps.102.1 million YoY, primarily due to the following variations: • A Ps.104.1 million decrease in income tax expense, mainly due to a lower taxable base at Cancún Airport. • A Ps.2.0 million increase in deferred income taxes, primarily in Mexico, partially offset by a decrease in Colombia resulting from the change in the amortization method of the concession. Net Majority Income

ASUR 3Q26 Page 7 of 33 In 3Q26, ASUR reported a 2.1% increase in Net Majority Income to Ps.2,158.8 million, compared to Ps.2,114.6 million in 3Q25. The YoY increase was driven primarily by lower current income tax expense in Mexico and Colombia, as well as a gain on forward contracts, partially offset by a higher foreign exchange loss in Mexico. In 3Q26, ASUR reported earnings of Ps.7.1960 per common share and US$3.9825 per ADS (each ADS represents ten Series B common shares). This compares with earnings per common share of Ps.7.0486 and US$3.9009 per ADS in the same period of the prior year. Net Income Net Income for 3Q26 totaled Ps. 2,307.9 million, compared to Ps.2,211.3 million in 3Q25, representing a YoY increase of 4.4%, or Ps.96.5 million. Consolidated Financial Position As of September 30, 2026, airport concessions represented 6 8.3% of the Company’s total assets, investment properties represented 8.4%, current assets represented 19.6%, and other assets represented 3.7%. As of September 30, 2026, cash and cash equivalents totaled Ps.20,091.8 million, an 80.7% increase from Ps.11,116.3 million as of December 31, 2025. Cash was distributed as follows: Mexico, Ps.13,008.2 million; Brazil & Others, Ps.3,079.0 million; Colombia, Ps.2,478.2 million; the United States, Ps.614.6 million; and Puerto Rico, Ps.911.8 million. At the close of 3Q26, shareholders’ equity totaled Ps.51,775.5 million, representing 34.8% of total assets, while liabilities totaled Ps.97,151.2 million, representing 65.2% of total assets. Deferred liabilities represented 3.5% of total liabilities. Total debt increased 154.6% to Ps.69,969.9 million at the end of 3Q26, from Ps.27,486.6 million as of December 31, 2025. The increase was primarily due to the addition of Ps.21,009.2 million in debt from Brazil & Other s and a Ps.22,225.1 million unsecured bridge loan obtained in Mexico on August 14, 2026. As of September 30, 2026, 26.5% of ASUR’s debt was denominated in Mexican pesos, 46.4% in U.S. dollars, and 27.1% in Brazilian reais. Net debt to LTM EBITDA stood at 2.6x at the end of 3Q26, compare d to net debt to LTM EBITDA of 0.2x as of September 30, 2025. The interest coverage ratio was 5.2x as of September 30, 2026 , compared to 12.8x as of September 30, 2025.

Excluding Construction Costs, they increased 2.2%, or Ps.37.3 million, primarily reflecting lower concession fees, electricity costs, technical assistance fees, cost of sales from direct commercial operations, insuran ce and surety bonds, tax recoveries, and adjustments. These decreases were partially offset by higher salaries and wages, professional fees, security and cleaning services, depreciation and amortization, and maintenance expenses. Cost of Services increased 4.0%, primarily due to higher salaries and wages, professional fees, security and cleaning services, and maintenance and conservation. These increases were partially offset by lower electricity costs, cost of sales from direct commercial operations, insurance and surety bonds, tax recoveries, and adjustments. Administrative Expenses increased 25.3%, primarily due to higher personnel costs. Technical Assistance Fees paid to ITA decreased 31.6%. Concession Fees, which include fees paid to the Mexican government, decreased 6.6%, primarily due to a lower tariff calculation base. Depreciation and Amortization increased 12.2% YoY, primarily reflecting the recognition of capital investments completed to-date.

ASUR 3Q26 Page 13 of 33 During 3Q26, ASUR’s operations in Mexico reported a Comprehensive Financing Loss of Ps.456.2 million, compared to a loss of Ps.372.3 million in 3Q25. The increase was mainly driven by a higher foreign exchange loss, which totaled Ps.812.9 million in 3Q26, compared to Ps.378.6 million in 3Q25. The 3Q26 foreign exchange loss primarily reflected the 3.4% depreciation of the Mexican peso against the U.S. dollar based on the closing exchange rate, and 1.2% average appreciation together with a lower U.S. dollar -denominated net monetary asset position compared to 3Q25 . This compares with quarter-end and average appreciations of 2.6% and 1.1%, respectively, in 3Q25. Interest expense increased 64.8 %, or Ps. 194.2 million, primarily reflecting the Ps.6,390.0 million loan entered into on December 5, 2025, and the US$1,230 million syndicated loan entered into on August 31, 2026. Interest income decreased 57.0%, or Ps.174.5 million, primarily due to lower invested cash balances. ASUR entered into three foreign exchange forward contracts to hedge currency exposure in January and June 2026, generating a gain of US$42.0 million.

ASUR's Mexican operations reported Operating Profit of Ps.2,816.1 million in 3Q26, resulting in an Operating Margin of 42.2%, compared to Operating Income of Ps.3,181.9 million and an Operating Margin of 49.1% in 3Q25. Adjusted Operating Margin, which excludes the impact of IFRIC 12 related to the construction or enhancement of concession assets and is calculated using revenues excluding Construction Services, was 62.3% in 3Q26, compared to 65.6% in 3Q25. EBITDA decreased 9.5%, or Ps.331.4 million, to Ps.3,164.7 million in 3Q26, compared to Ps.3,496.1 million in 3Q25, mainly reflecting lower passenger traffic and the appreciation of the Mexican peso against the U.S. dollar . EBITDA Margin decreased to 47.4% from 54.0%. Adjusted EBITDA Margin, which excludes the impact of IFRIC 12 related to the construction or enhancement of concession assets, decreased to 70.0% in 3Q26 from 72.1% in 3Q25. Mexico Tariff Regulation The Mexican Ministry of Communications, Infrastructure and Transportation regulates the majority of ASUR’s activities by setting maximum rates, which represent the maximum possible revenues allowed per traffic unit at each airport. ASUR’s accumulated regulated revenue in Mexico, updated according to tariff regulations, amounted to Ps.10,720.6 million as of September 30, 2026. The weighted implicit tariff was Ps.351.7 (in December 2025 pesos) per traffic unit, representing approximately 70.3% of total revenue for the period, excluding construction revenue.

ASUR 3Q26 Page 14 of 33 The compliance with maximum tariffs is reviewed annually at the end of the fiscal year by the Ministry of Communications, Infrastructure, and Transportation. Mexico Capital Expenditures Capital expenditures in Mexico totaled Ps.2,241.5 million in 3Q26, compared to Ps.1,681.8 million in 3Q25. These investments were primarily allocated to the modernization of ASUR's Mexican airports under its Master Development Program. For the nine months of 2026, capital expenditures totaled Ps.4,414.6 m illion, compared to Ps.3,461.1 million in the same period of 2025. Review of Puerto Rico Operations The following analysis compares the standalone results of ASUR's Puerto Rico operations for the three- and nine- month periods ended September 30, 2026 and 2025. As of September 30, 2026, ASUR’s valuation of its investment in Aerostar (Puerto Rico), in accordance with IFRS 3 “Business Combinations,” resulted in the following effects on the Balance Sheet: i) the recognition of a net intangible asset of Ps.4,352.7 million; (ii) goodwill of Ps.863.2 million (net of an impairment loss of Ps.4,719.1 million); (iii) deferred income tax liability of Ps.435.3 million; and (iv) a minority interest of Ps.4,758.7 million in shareholders' equity.

Total Operating Costs and Expenses for the Colombian airport operations increased 8.8% YoY in 3Q26 to Ps.888.5 million. Excluding construction costs, operating costs and expenses decreased 7.7% to Ps.751.2 million, primarily reflecting the favorable impact following the adjustment to the concession amortization method introduced in 3Q25. Thia was partly offset by higher personnel, cleaning, electricity costs and maintenance and conservation. Cost of Services increased 27.7%, or Ps. 53.7 million, primarily due to higher personnel, security and surveillance, cleaning, electricity and maintenance costs. Construction Costs increased 5 Ps.134.7 to 137.3 million in 3Q26 from Ps.2.6 million in 3Q25. Concession Fees paid to the Colombian government increased 7.7%, primarily reflecting higher regulated and non-regulated revenues compared to the same period of the prior year. Depreciation and Amortization decreased 29.9%, primarily due to a Ps.130.4 million adjustment to the concession amortization method introduced in 3Q25.

Operating Profit for the Colombian operations was Ps.283.7 million in 3Q26, compared to Ps. 144.3 million in 3Q25. The increase primarily reflected a Ps.130.4 million favorable impact in depreciation and amortization following the change in the concession-amortization methodology. Operating Margin increased to 2 4.2% in 3 Q26 from 15 .0% in 3 Q25. Adjusted Operating Margin, which excludes the impact of IFRIC 12 related to the construction or enhancement of concession assets, increased to 27.4% from 15.1% in 3Q25. EBITDA increased to Ps.590.0 million in 3Q26 from Ps.580.9 million in 3Q25, while the EBITDA Margin decreased to 50.3% from 60.5% in 3Q25. Adjusted EBITDA Margin, which excludes the impact of IFRIC 12 related to the construction or enhancement of concession assets, decreased to 57.0% in 3Q26, compared to 60.6% in 3Q25. Colombia Capital Expenditures Capital expenditures totaled Ps.138.5 million in 3Q26, compared to Ps.3.0 million in 3Q25. For the nine months of 2026, capital expenditures totaled Ps.202.9 million, compared to Ps.9.9 million in the same period of 2025. Colombia Tariff Regulation The Special Administrative Unit of Civil Aeronautics is responsible for setting, collecting, and enforcing the fees, tariffs, and charges for the provision of aeronautical and airport services, or those generated from concessions, authorizations, licenses, or any other type of revenue or asset. Resolution No. 04530 issued on September 21, 2007, established the tariffs for the fees and charges granted to the concessionaires of José María Córdova Airport in Rionegro, Olaya Herrera in Medellín, Los Garzones in Montería, El Caraño in Quibdó, Antonio Roldán Betancourt in Carepa, and Las Brujas in Corozal. The resolution also sets forth the methodology for updating these tariffs and the mechanisms to collect such fees and tariffs. Regulated revenues amounted to Ps.718.0 million in 3Q26 and Ps.2,043.4 million during 9M26. Review of U.S. Operations The following discussion presents the standalone results of the U.S. commercial operations for the three - and nine-month period s ended September 30, 2026, reflecting the third full quarter of operations following the acquisition of ASUR US Airports on December 11, 2025. ASUR holds the rights to develop and operate retail and food & beverage concessions under long-term agreements at major U.S. airport terminals, including Los Angeles International Airport (LAX), Chicago O’Hare (ORD), and John F.

ASUR Airports operates under a cost structure that includes fixed lease obligations with airport authorities, resulting in lower operating margins, particularly during the initial phase of operations. Total Operating Costs and Expenses for 3Q26 were Ps. 294.1 million, primarily reflecting lease expense s payable to the airport authorities, personnel costs, and insurance and surety expenses, partially offset by favorable IFRS 16 accounting effects related to lease agreements with U.S. airport authorities.

During 3Q26, ASUR Airports reported a comprehensive financing loss of Ps.11 2.4 million, primarily reflecting Ps.114.4 million in financial expenses related to the measurement and subsequent accretion of lease liabilities associated with agreements with the U.S. airport authorities, in accordance with IFRS 16. Because these agreements are accounted for as lease obligations under IFRS 16, a portion of the lease payments is recognized as finance costs over the lease term rather than as operating expenses.

ASUR 3Q26 Page 23 of 33 Definitions Concession Services Agreements (IFRIC 12 interpretation ). In Mexico, Puerto Rico, and Brazil & Others, 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, as well as 53.5% in Ecuador, 20.2% in Curazao, 2.5% in Costa Rica and 61.7% in Bello Horizonte. Other than these operations, ASUR owns (directly or indirectly) 100% of its subsidiaries. EBITDA is calculated as consolidated net income plus income tax, share of loss of investments accounted for using the equity method, extraordinary items, comprehensive financing costs and depreciation and amortization. EBITDA should not be considered an alternative to net income as an indicator of our operating performance or 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 is calculated as consolidated EBITDA adjusted by certain items that include the impact of IFRS16 in connection with ASUR Airports and add back extraordinary items. Adjusted EBITDA Margin is calculated by dividing Adjusted Consolidated EBITDA by Total Revenue Excluding Construction Services Revenue for Mexico, Colombia, Puerto Rico and Brazil & Others, and exclude the effect of IFRIC 12 with respect to the construction of, or improvements to, concessioned assets. IFRIC 12 requires ASUR to include in its income statement a revenue line reflecting revenues from the construction or improvement of concession assets during the relevant period. The same amount is recognized under the expense line “Construction Costs,” as ASUR engages third parties to provide construction services. In Mexico, Puerto Rico, Colombia and Brazil & Others, construction revenues and construction costs are included in ASUR’s income statement as a result of the application of IFRIC 12. Construction revenues therefore have no impact on EBITDA but affect the EBITDA margin, as the increase in revenues attributable to construction revenues does not result in a corresponding increase in EBITDA. Like EBITDA Margin, Adjusted EBITDA Margin should not be co nsidered an indicator of our operating performance or an alternative to cash flow as an indicator of liquidity. It is not defined under U.S. GAAP or IFRS and may be calculated differently by different companies. About ASUR Grupo Aeroportuario del Sureste, S.A.B. de C.V.
