Business Update on COVID-19

Travel Restrictions Imposed by Governments to Mitigate the Impact of COVID-19

Since March 16, 2020, various governments have issued flight restrictions for different regions of the world to limit the breakout of the COVID-19 virus. With respect to the airports ASUR operates:

The United States Centers for Disease Control and Prevention (CDC) requires negative COVID-19 tests for all air passengers entering the US as of January 26, 2021. According to the CDC, pre- and post-trip testing is a critical layer in slowing the introduction and spread of COVID-19. This strategy is consistent with the current phase of the pandemic and intended to more effectively protect the health of US citizens. Within three days of departure to the United States, passengers are required to obtain a viral test and provide the airline on which they are traveling written documentation of their negative test result or documentation that evidences that they have recovered from COVID-19. Additionally, the CDC recommends that passengers who tested negative before their flight get tested again 3 to 5 days after arrival in the US (unless they recovered from COVID-19 in the past 3 months) and for unvaccinated people to self-quarantine for 7 days after their arrival (or for 10 days if they do not get tested). Beginning January 7, 2021, Canada also established testing requirements for air passengers travelling to the country. Subsequently, the Canadian government suspended flights between Canada, Mexico and the Caribbean until April 30, 2021, certain Canadian airlines voluntarily extended the suspension of such flights past April 30, 2021. Several Mexican airports have implemented COVID-19 test sites certified by the government, which are operated by third parties, who have been granted the space to provide this service at the airports of Cancun, Merida, Veracruz and Oaxaca.

In Puerto Rico, on March 30, 2020, the Governor of Puerto Rico, through an executive order of indefinite term, imposed a two-week quarantine on all passengers arriving at the LMM Airport.

To further strengthen health controls on arrival, starting July 15, 2020, the Governor of Puerto Rico began implementing the following additional measures: all passengers must wear a mask, complete a mandatory flight declaration form from the Puerto Rico Health Department, and submit negative results of a PCR molecular COVID-19 test taken 72 hours prior to arrival to avoid having to undergo the two-week quarantine. Passengers can also opt to take the COVID-19 test in Puerto Rico (not necessarily at the airport), to be released from quarantine (estimated to take between 24-48 hours). The policy has since been adjusted and fully-vaccinated domestic travelers no longer need to submit negative COVID-19 test results to avoid undergoing the two-week quarantine. Unvaccinated domestic travelers and all international travelers must still abide by the July 15, 2020 measures.

In Colombia, all incoming international flights, including connecting flights in Colombia, were suspended by the Colombian government starting March 23, 2020. This suspension was extended through September 15, 2020, with exceptions for humanitarian emergencies, transportation of cargo and goods, and fortuitous events or force majeure. Similarly, domestic air travel in Colombia was suspended starting March 25, 2020 until September 1, 2020. As of October 2, 2020, passenger commercial flights had been reestablished at all of ASUR's Colombian airports. International flights were allowed by the government starting September 16, 2020 with the Rionegro Airport resuming international flights on September 19, 2020. A negative COVID-19 test is not required to enter the country, although entrants must complete an immigration form and report any flu-like symptoms that occur within 15 days of arrival in Colombia.

Mexico and/or the United States may issue, and Colombia may re-issue, flight restrictions similar to those issued in other parts of the world, which would cause a significant further reduction in ASUR's operations.

Impact of COVID-19 on ASUR's 1H21 Passenger Traffic

The COVID-19 pandemic has disrupted the travel industry and governments have introduced travel bans and restrictions. As a result, ASUR's passenger traffic declined in the second half of March 2020 and continued to decline dramatically throughout its airport network in the following months. However, traffic has progressively recovered since June 2020. The table below shows the YoY change in passenger traffic during 1H21:

Accounts Receivables

Starting in mid-March of 2020, some of the airlines and other clients and tenants that operate in ASUR's airports asked for assistance, either through discounts on payments owed to ASUR or by an extension on those payments. Three of ASUR's principal airline customers, Aeromexico, Avianca Holdings and LATAM Airlines Group, have filed for Chapter 11 bankruptcy protection in the United States, although they have continued making payments in the ordinary course, as permitted by the relevant courts. The Company remains in commercial discussions with those clients and tenants regarding their contracts. Notwithstanding these discussions, ASUR believes it has sufficient liquidity to meet its obligations and continue operating in the normal course.

Cost Reduction Initiatives

ASUR has introduced cost reduction initiatives across its three countries of operations. Most of the Company's cost structure is fixed, except for concession fees across operations and the technical assistance fee in Mexico, which are both variable costs. The impact from these cost reduction measures is not expected to be significant vis à vis the potential decline in revenues resulting from the disruption in passenger traffic across the Company's operations.

Consolidated Revenues

ConsolidatedRevenues for 2Q21 increased 139.3% YoY, or Ps.2,462.3 million, to Ps.4,229.3 million and rose 3.9%, or Ps.159.9 million when compared to the pre-pandemic levels of 2Q19. The YoY increase was mainly due to:

•	A 312.7% increase in revenues from non-aeronautical services to Ps.1,550.1 million. Mexico contributed Ps.1,071.8 million, while Puerto Rico and Colombia accounted for Ps.381.1 million and Ps.97.2 million, respectively;

•	A 333.5% increase in revenues from aeronautical services to Ps.2,313.7 million. Operations in Mexico contributed Ps.1,555.9 million, while Puerto Rico and Colombia contributed Ps.521.6 million and Ps.236.2 million, respectively; and

•	A 57.4%, or Ps.492.2 million, decline in construction services revenues to Ps.365.5 million, principally in Mexico.

Excluding revenues from construction services, which are deducted as costs under IFRS accounting standards, total revenues would have increased 324.9% YoY to Ps.3,863.8 million. Compared to pre-pandemic levels of 2Q19, revenues excluding construction services declined 4.0%, with declines of 4.5% in revenues from non-aeronautical services and 3.7% in revenues from aeronautical services. Excluding revenues from construction services, Mexico accounted for 68.0% of total revenues in 2Q21, while Puerto Rico and Colombia represented 23.4% and 8.6%, respectively.

Commercial Revenues in 2Q21 increased 373.9% YoY to Ps.1,434.6 million, mainly reflecting the 1,385.4% recovery in passenger traffic. Compared to pre-pandemic levels of 2Q19, commercial revenues increased 2.0%. Commercial revenues increased YoY across ASUR's regions of operations: 522.3% to Ps.959.4 million in Mexico, 244.8% to Ps.378.6 million in Puerto Rico and 149.4% to Ps.96.7 million in Colombia.

Commercial Revenues per Passenger wasPs.118.8 in 2Q21, compared to Ps.353.2 in 2Q20 and Ps.99.7 in 2Q19.

Consolidated Operating Costs and Expenses

Consolidated Operating Costs and Expenses during 2Q21, including construction costs, declined 2.2% YoY, or Ps.50.6 million, to Ps.2,219.4 million, but increased 11.9%, when compared to the pre-pandemic levels of 2Q19.

Excluding construction costs, operating costs and expenses increased 31.3% YoY, or Ps.441.6 million, and declined 8.2% when compared to 2Q19. The YoY increase was mainly due to the following variations:

•	Mexico:increased63.6%, or Ps.401.8 million, mainly due to higher technical assistance and concession fees together with increases in energy, maintenance and security expenses, as well as higher cost of sales from directly operated stores, together with higher social security contributions.

•

Puerto Rico:declined 4.4%, or Ps.24.3 million, principally reflecting the reimbursement Ps.11.5 million in expenses in 2Q21 from both the cancellation of a security contract with the municipality of Carolina and a reimbursement provided by the TSA (Transportation Security Administration) in connection with offering security, as required by the U.S. government, also contributed to lower costs. The YoY comparison also benefited from an Ps.8.1 million increase in the provision for bad debt in 2Q20 in connection with the COVID-19 pandemic and certain cost reductions in 2Q21 as a result of the FX translation impact (the average US$ exchange rate declined to Ps.20.0 from Ps.23.3) of: i) 8%, or Ps.23.8 million, in depreciation and amortization charges; ii) 13.9%, or Ps.13.9 million in payroll expenses; iii) 22.7%, or Ps.12.4 million in insurance and bonds. This was partly offset by increase of Ps.22.8 million in cost of sales of directly operated convenience stores. It should be noted that in 2Q21 funds from the grant under the Cares Act were not used to reimburse expenses, the grant has a balance for future reimbursements of US$8.2 million.

•	Colombia: increased 28.9%, or Ps.64.1 million, mainly due to increases of 552.2%, or Ps.53.6 million, in concession fees. In addition, cost of services increased 28.8%, or Ps.25.1 million, principally reflecting higher energy costs, professional fees,taxes and duties as well as security fees.

ASUR 2Q21 Page 7 of 29

Cost of Services increased YoY by 23.6%, or Ps.188.2 million. This was principally due to a 45.7%, or Ps.176.6 million, increase in Mexico, reflecting mainly higher energy, maintenance and security expenses, together with higher cost of sales at stores operated directly by ASUR, and higher social security contributions.

Construction Costs declined 57.4% YoY, or Ps.492.2 million. This was mainly driven by YoY declines of 56.7%, or Ps.416.8 million in Mexico, 61.7%, or Ps.74.4 million, in Puerto Rico and 75.2%, or Ps.0.9 million, in Colombia.

Administrative Expenses that reflect administrative costs in Mexico declined 3% YoY.

ConsolidatedTechnical Assistance increased to Ps.94.9 million from negative Ps.6,529 million in 2Q20, mainly reflecting higher EBITDA in Mexico in 2Q21.

Concession Fees increased 302.3% YoY, principally due to increases of 629.5% in Mexico, 552.2% in Colombia and 43.4% in Puerto Rico, mainly due to higher regulated revenues, a factor in the calculation of the fee.

Depreciation and Amortization declined 3.6%, or Ps.18.4 million, principally due to a decline of 11.6%, or Ps.23.8 million in Puerto Rico mainly due to FX currency conversion as the average US$ exchange rate in the period declined to Ps.20.0 from Ps.23.3 in the same quarter last year.

Consolidated Operating Profit (Loss) and EBITDA

In 2Q21, ASUR reported a Consolidated Operating Profit of Ps.2,009.9 millionresulting in an Operating Margin of 47.5%, compared to Operating Loss of Ps.0.5.1 million and a negative 26.1% margin in 2Q20. This was mainly the result of the recovery in passenger traffic from the gradual recovery in travel demand as COVID-19 vaccination programs advance worldwide and the resulting increase in revenues, together with a marginal increase in costs.

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, and which is calculated as operating profit or loss divided by total revenues less construction services revenues, was 52.0% in 2Q21 compared with negative 50.8% in 2Q20 and 56.9% in 2Q19 (52.8% when excluding a Ps.163.6 million extraordinary insurance recovery claim in Puerto Rico).

EBITDA increased to Ps.2,502.8 million in 2Q21 from Ps.51.2 million in 2Q20. By country of operations, EBITDA increased YoY by Ps.1,937.4 million to Ps.1,797.3 million in Mexico, by Ps.310.5 million to Ps.548.8 million in Puerto Rico and by Ps.203.8 million to Ps.156.7 million in Colombia. Consolidated EBITDA margin in 2Q21 was 59.2% compared to 2.9% in 2Q20. Comparable EBITDA was 51.1% in 2Q19 excluding a Ps.162.6 million one-time insurance claim recovery in Puerto Rico in connection with Hurricane Maria in 2017.

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 64.8% in 2Q21, compared to 5.6% in 2Q20, and 69.5% in 2Q19.

In2Q21 ASUR reported a Ps.181.4 million Consolidated Comprehensive Financing Loss, compared to a Ps.180.5 million loss in 2Q20.

ASUR 2Q21 Page 8 of 29

During 2Q21 ASUR reported a foreign exchange loss of Ps.44.1 million, resulting from the 2.0% quarterly average appreciation of the Mexican peso against the U.S. dollar (2.6% quarter-end depreciation) during the period together with a U.S. dollar net asset position. This compares to a Ps.2.3 million foreign exchange loss in 2Q20 resulting from the 0.6% quarterly average appreciation of the Mexican peso (1.7% quarter-end depreciation) on a U.S. dollar net asset position.

Interest expense declined Ps.72.6 million, or 27.7% YoY, mainly driven by a decline of Ps.43.6 million, or 79.5%, in interest payments in Colombia on fair value loan repayments recognized under IFRS 3. Mexico also contributed with a Ps.11.4 million, or 14.9%, decrease in interest payments reflecting a lower TIIE interest rate.

Interest income declined by Ps.31.7 million, or 37.9% YoY reflecting the lower interest rates and a lower average cash balance position.

Income Taxes

Income Taxes for 2Q21 increased Ps.575.5 million YoY, principally due to the combination of:

•	A Ps.635.6 million increase in income taxes, reflecting mainly a higher taxable income base in Mexico and Colombia resulting mainly from the YoY recovery in revenues following the negative impact of COVID-19 which fully impacted the Company in 2Q20.

•	A Ps.60.1 million decline in deferred income taxes. This mainly reflects a Ps.95.4 million decrease in deferred income taxes in Mexico, principally related to a lower tax benefit in certain airports, and a Ps.37.0 million tax benefit in Colombia.

Majority Net Income (Loss)

ASURreported Majority Net Income ofPs.1,231.7 million for 2Q21, compared to a Majority Net Loss of Ps.520.3 million in 2Q20. This resulted in earnings per common share in 2Q21 of Ps.4.1055, or earnings per ADS of US$2.0624 (one ADS represents ten series B common shares). This compares with earnings per share of Ps.1.7343 and earnings per ADS of US$0.8712 for the same period last year.

Net Income (Loss)

ASUR reported Net Income of Ps.1,329.8 million in 2Q21, compared to a Net Loss of Ps.545.5 million in 2Q20, a YoY increase of 335.2%, or Ps.1,895.3 million.

Total Mexico Operating Costs and Expenses for 2Q21 declined 1.1% YoY and increased 35.9% when compared to 2Q19.

Excluding construction costs, operating costs and expenses increased 63.6% or Ps.401.8 million, mainly reflecting higher technical assistance and concession fees, as well as increases in energy, maintenance and security costs. Higher cost of sales at stores operated by ASUR and an increase in social security contributions also contributed to higher costs. This mainly reflects the reopening of Terminals 2 and 3 at Cancun Airport which were closed in 2Q20 and an increase in revenues and EBITDA on which the concession and technical assistance fees are based on. Compared to 2Q19, operating costs and expenses, excluding construction costs in increased 8.2%.

Cost of Services increased 45.7% YoY, mainly reflecting higher energy, maintenance and security expenses, together with higher cost of sales at stores operated directly by ASUR and an increase in social security contributions.

Administrative Expenses increased4.8% YoY.

The Technical Assistance fee paid to ITA increased to Ps.93,920 from negative Ps.7,332 in 2Q20, reflecting higher EBITDA in Mexico, a factor in the calculation of the fee.

Concession Fees, which include fees paid to the Mexican government, increased 629.5%, mainly as a result of the increase in regulated revenues, a factor in the calculation of the concession fee.

Depreciation and Amortization increased 11.0% YoY, reflecting higher investments to date.

In 2Q21, ASUR's Mexico operations reported a Ps.58.8 million Comprehensive Financing Loss, compared to a Ps.3.0 million loss in 2Q20. This was mainly due to a higher foreign exchange loss in 2Q21 which amounted to Ps.44.1 million and which resulted from the 2.0% average quarterly appreciation of the Mexican peso (2.6% at quarter-end) against the U.S. dollar on a foreign currency net asset position. This compares with a Ps.2.4 million foreign exchange loss 2Q20, resulting from the 0.6% average quarterly appreciation of the Mexican peso during that period (1.7% at quarter-end) and a higher foreign currency net asset position.

Interest expense decreased 14.9% YoY reflecting a lower TIIE interest rate and a decline in the debt balance, partially offsetting the 38.4% YoY reduction in interest income.

Figures in pesos at the average exchange rate Ps.20.0238 = US. 1.00

During 2Q21, total Operating Costs and Expenses at LMM Airport declined 14.5% YoY to Ps.581.2 million. Construction costs in the quarter declined 61.7% to Ps.46.2 million from Ps.120.6 million in 2Q20.

Excluding construction costs, operating costs and expenses decreased 4.4% YoY, or Ps.24.3 million, to Ps.535.0 million. This mainly reflects the reimbursement of Ps.11.5 million in expenses in 2Q21 from both, the cancellation of a security contract with the municipality of Carolina together with the reimbursement of security expenses provided by the TSA to airports in accordance with the LEO law. Comparisons also benefited from an Ps.8.1 million provision for bad debt incurred in 2Q20 as a result of the COVID-19 pandemic. Lower costs also reflect savings of Ps.23.8 million in depreciation and amortization, Ps.13.9 million in salaries, and Ps.12.4 million in insurance and bonds mainly due to the effect of foreign currency conversion resulting from an average exchange rate of Ps.20.0 in 2Q21 compared to Ps.23.3 in 2Q20. This was partly offset by increase of Ps.22.8 million in cost of sales of directly operated convenience stores.

It should be noted that in 2Q21 the company did not apply funds from the grant under the Cares Act to reimburse expenses, the grant has a balance for future reimbursements of US$ 8.2 million.

Cost of Services declined 4.1% YoY, or Ps.13.5 million.

Concession Fees paid to the Puerto Rican government increased Ps.12.9 million, in line with the concession agreement.

Depreciation and Amortization declined 11.6% YoY, or Ps.23.7 million, mainly reflecting the FX translation impact as the average Mexican peso exchange rate fluctuated to Ps.20.0 per dollar in 2Q21, from Ps.23.3 per dollar in 2Q20.

Total Operating Costs and Expenses in Colombiaincreased28.4% YoY to Ps.286.0 million in 2Q21. Excluding construction costs, operating costs and expenses declined 28.9% YoY to Ps.285.7 million.

Cost of Services increased 28.8% YoY, or Ps.25.1 million, mainly reflecting increases in energy expenses, professional fees, taxes and duties as well as higher security costs resulting from the recovery in passenger traffic.

Construction Costs declined 75.2% YoY, or Ps.0.9 million, reflecting lower complementary works to concessioned assets during the period compared to the prior year.

Concession Fees,which include feespaid to the Colombian government, increased 552.2% YoY, mainly reflecting the increase in regulated and non-regulated revenues during the period.

Depreciation and Amortization declined Ps.14.8 million, principally reflecting the FX translation impact from the depreciation of the Colombian peso against the Mexican peso.

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

ASUR 2Q21 Page 20 of 29

Airplan's regulated revenues for 2Q21 amounted to Ps.236.1 million.

Definitions

Concession Services Agreements (IFRIC 12 interpretation). In Mexico and Puerto Rico,ASUR is required byIFRIC 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.
