RISK FACTORS

The following risk factors related to the Issuer and the Corporate Restructuring have been identified. If any of the risks described below were to occur, it could have a material adverse effect on the Transaction, as well as on the Issuer's business, financial condition, or results of operations. The risks described below are not the only ones that the Issuer and the Transaction generally face. Additional risks and uncertainties that are not known to the Issuer and are not considered material may also have a material adverse effect on the Transaction and the Issuer's business, financial condition, or results of operations.

Risk Factors Related to the Issuer

The information corresponding to this section may be consulted in the Annual Report, which is incorporated by reference to this Information Statement. The Annual Report may be consulted on the Stock Exchange website at www.bmv.com.mx and on the Issuer's website at www.asur.com.mx/inversionistas.

Risk Factors Inherent in the Corporate Restructuring

The Transaction may not be completed.

As of the date of this Information Statement, the Issuer cannot confirm that the Transaction will actually be completed in its entirety or under the terms set forth in this Statement. As noted above, the Transaction is subject to obtaining various authorizations and complying with other conditions customary in this type of transaction, as well as the implementation of various preliminary steps. The consolidated financial statements issued on the date the Transaction takes effect may differ from the unaudited pro forma financial statements attached to this document.

Some preliminary steps related to the Corporate Restructuring may not be executed.

The Corporate Restructuring requires a series of preliminary legal and corporate actions to be taken. The implementation of some of these legal and corporate actions may not be effectively completed due, among other reasons, to the existence of unusual conditions for this type of transaction or significant costs. Failure to complete some of the steps related to the Corporate Restructuring could affect the Issuer's financial position and operating results.

Unforeseen operating costs.

The Issuer will incur costs related to the Transaction, mainly those arising from accounting, tax, legal, and other professional services; financial costs related to the financing of the Transaction; costs of hiring executives; and costs arising from consolidating assets and information systems. These costs, whether incurred before or after the Transaction, could be higher than expected and could have a material adverse effect on our business, financial condition, results of operations, and cash flows.

In connection with the Transaction, we will incur additional debt in amounts that are significant relative to our current debt levels.

To complete the Transaction, we will incur significant amounts of debt that will increase our current debt levels, which could have an adverse effect on our capital structure and reduce, to the extent not offset by the cash flow generated by the integration of CPC Aeroportos, the Issuer's available cash flow. The contracts documenting the financing will contain various affirmative and negative covenants that could limit our operations (including limitations on contracting additional liabilities, capital investments, dividend payments, certain financial ratios, among others).

Consequently, the Issuer's ability to distribute dividends, finance acquisitions, expansions, maintenance, and investments, and maintain flexibility in the management of its business could be significantly limited, adversely affecting its operations, financial condition, future operating results, and the market price of its securities.

For a more detailed description of the financing to be contracted in connection with the Transaction, see "Detailed Information on the Transaction - Sources of Financing" in this Information Statement.

The expected benefits may not be realized in full or at the expected rate.

We cannot guarantee that the benefits described in the objectives of the Transaction will be captured in full and at the speed predicted.

The pro forma financial information presented is not necessarily indicative of future results and has not been audited.

The unaudited pro forma consolidated financial information included in this Information Statement is a preliminary estimate based on assumptions and is subject to change, adjustment, and review upon completion of the Transaction. Its purpose is to show the Issuer's financial statements after the Transaction and, therefore, does not represent the actual operating results that would have been achieved if the Transaction had been completed. Consequently, the pro forma financial information presented in this document may not reflect the financial situation or operating results of the Issuer.

The unaudited pro forma consolidated financial information included in this Information Statement is a preliminary estimate based on assumptions and is subject to change, adjustment, and revision upon completion of the Transaction. It was prepared based on available information and assumptions that the Issuer's management considers reasonable, and is not intended to reflect the actual consolidated operating results that would have been achieved if the Transaction had been carried out on the assumed dates, nor is it intended to project the consolidated operating results or financial position of the Issuer. The unaudited pro forma consolidated financial information of the Issuer included in this Information Statement should be read in conjunction with the Issuer's historical consolidated financial statements, the notes thereto, and the additional financial information included in its Annual Report.

CPC Aeroportos is an ongoing business and, as such, is subject to various risk factors that we cannot control.

CPC Aeroportos is a going concern and, as such, is subject to various risk factors that are currently beyond our control. These include, but are not limited to, supply risk, regulatory risk, labor disputes, third-party perceptions and reputational risk, and cybersecurity risk. The materialization of any of these risks or additional risks could have adverse effects on our results, financial condition, and stock price. In addition, the acquisition agreement contains limited indemnities, and we cannot assure you that the coverage will be sufficient to cover any potential damage caused by any contingency arising from the past operations of CPC Aeroportos or the acquisition.

Variation in the price of our shares.

As a result of the Corporate Restructuring to be carried out in accordance with the provisions of this Information Statement, we will acquire the business of CPC Aeroportos, which may be perceived negatively by investors and could affect the market price of our shares.

There can be no assurance that the Transaction will achieve the anticipated business growth opportunities, earnings-related benefits, cost savings, and other anticipated benefits.

There is no assurance that the Corporate Restructuring will achieve the business growth opportunities, profit benefits, cost savings, and other anticipated benefits for the Issuer. The Issuer believes that the Corporate Restructuring is justified by the anticipated benefits; however, the expected benefits may not materialize and other considerations under which the Corporate Restructuring was determined to be carried out may prove to be incorrect, since, among other things, such considerations were based primarily on publicly available information.

The Issuer may not be able to fully implement its business plans and strategies due to legal or regulatory limitations. The Issuer may face regulatory restrictions in the provision of services. As a result, the anticipated benefits may not be achieved as expected or may be delayed. To the extent that the Issuer incurs additional costs, achieves lower profits, or has fewer cost savings than expected, its operating results, financial condition, and share price could be affected.

The credit ratings assigned to the Issuer could be affected.

As a result of the Corporate Restructuring, the credit ratings assigned to the Issuer could be affected, depending on the different perceptions of the rating agencies regarding the acquisition of CPC Aeroportos.

Accounting treatment of the Transaction.

The incorporation of CPC Aeroportos' operations into the Issuer's results and financial position will be carried out in accordance with IFRS, the regulations governing the Issuer's consolidated financial statements.

The acquisition of CPC Aeroportos shares will be accounted for at the time the transaction is completed, applying the requirements of IFRS 3 "Business Combinations." For the purposes of the pro forma condensed combined financial statements, the excess of the consideration paid over the carrying amount of the net assets acquired was allocated to goodwill. However, once the acquisition is completed, the Issuer will account for the transaction within a period not exceeding 12 months, applying the purchase method as established by IFRS 3, identifying the assets acquired and liabilities assumed, measuring them at fair value, so that the goodwill in these pro forma condensed combined financial statements may be modified. Where applicable, material effects on the Issuer's accounts as a result of the Transaction could affect the Issuer's results.

Risk Factors Related to the Brazilian Market

Economic and political conditions in Brazil, Ecuador, and Curaçao could adversely affect the business and operating results.

The Operation could be adversely affected by the economic, political, social, legal, and regulatory conditions of the South American countries in which it seeks to expand its operations, particularly Brazil, Ecuador, and Curaçao, whose economies have structural characteristics and risks that differ from those of the Mexican market.

In Brazil, the macroeconomic environment is characterized by high sensitivity to commodity prices, exchange rate volatility, and a recent history of high inflation and interest rates. In addition, the country's fiscal policy faces structural pressures from public spending and ongoing reforms. Any depreciation of the Brazilian real against the Mexican peso or the U.S. dollar could increase operating costs and affect the value of investments. Likewise, regulatory processes related to airports and infrastructure in Brazil are complex and may involve delays in obtaining permits or executing projects.

In Ecuador, the political and regulatory environment has been volatile in recent years, including frequent changes in tax legislation and foreign investment policies. The dollarization of the economy, while reducing domestic exchange rate risk, limits the government's ability to implement monetary policies that mitigate financial crises, which could affect the macroeconomic stability. In addition, security conditions and social unrest in certain regions could affect the operation of airport services.

In Curaçao, although the economy is considered relatively stable within the Caribbean, its small size, dependence on tourism, and link to the Dutch economy make it particularly sensitive to external shocks, including fluctuations in international tourism and in the exchange rate of the Netherlands Antillean guilder against the US dollar. Changes in the political and economic relationship with the Kingdom of the Netherlands could also create regulatory or fiscal uncertainty.

In general, South American economies tend to experience higher levels of political and economic volatility than other markets, due to factors such as institutional instability and social tensions. Any deterioration in macroeconomic, security, or regulatory conditions in these countries could adversely affect the operations, financial results, and expected profitability of the Issuer's investments in the region.

Changes in tax laws or changes in their interpretation may increase the tax burden and, as a result, adversely affect profitability.

Governments regularly implement changes in tax regimes that may increase the tax burden in the countries where the airports are located. These changes include modifications in tax rates and duties and, on occasion, the enactment of temporary taxes, the proceeds of which are earmarked for designated government purposes. The effects of these tax reform measures, proposals, and any other changes resulting from the enactment of additional tax reforms have not been and cannot be quantified.

Estimates and associated risks

The information included in this Information Statement reflects the Issuer's perspective on future events and may contain information about financial results, economic conditions, trends, and uncertain events. In evaluating such provisions or estimates, shareholders should consider the factors described in this section and other cautionary statements contained in this Information Statement or in any other document disclosed to the public in connection with the Transaction. These risk factors and projections describe circumstances that could cause actual results to differ materially from those expected.

Notes to the Pro Forma Financial Statements for the year ended December 31, 2024

Description of the transaction

ASUR entered into a purchase agreement with Motiva to acquire all of its issued and outstanding shares in CPC Aeroportos, a wholly owned subsidiary of Motiva.

CPC Aeroportos has interests in 20 airports with concessions in Brazil, Ecuador, Costa Rica, and Curaçao. The portfolio includes Quito International Airport in Quito, Ecuador; Juan Santamaría International Airport in San José, Costa Rica; Curaçao International Airport in Curaçao; Confins International Airport in Brazil; as well as Pampulha Airport, the Southern Block airports, and the Central Block airports in Brazil.

The acquisition represents an important step in ASUR's expansion strategy in the region, adding four new markets in Latin America and the Caribbean, including Latin America's largest aviation market by passenger numbers, Brazil, to ASUR's current presence in Mexico, Colombia, and Puerto Rico. This acquisition will add more than 45 million passengers to the 71 million recorded by ASUR in 2024, consolidating ASUR as the leading airport operator in the Americas. Of the 20 airports in CPC Aeroportos' portfolio, 17 have more than 15 years remaining on their concession terms.

Motiva Infraestrutura de Mobilidade S.A. is Brazil's largest mobility infrastructure company, operating in the toll road, railway, and airport segments. In the airport sector, it operates 17 units in Brazil and three abroad, serving around 45 million passengers per year.

The closing of the transaction, expected in the first half of 2026, is subject to customary closing conditions.

Basis for preparing the pro forma consolidated financial statements of ASUR and Motiva Infraestrutura de Mobilidade S.A. as of September 30, 2025, and December 31, 2024, and 2023.

The preparation of ASUR's pro forma consolidated financial statements as of September 30, 2025, and December 31, 2024, and 2023 complies with the guidelines for the consolidation of subsidiaries with a functional currency different from the parent company's presentation currency.

Considering that the results and financial position of Motiva Infraestrutura de Mobilidade S.A. (which does not have a currency corresponding to hyperinflationary economies) and has a functional currency (reais) different from the presentation currency (Mexican peso) are converted to the presentation currency, as described in the foreign currency conversion process shown below:

(i)       Assets and liabilities recognized in the statement of financial position are converted at the exchange rate in effect on the closing date of that statement of financial position.

(ii)      The capital of each financial statement presented is converted at the historical exchange rate.

(iii)     Income and expenses recognized in the statement of income are converted at the average exchange rate for each month (except when this average is not a reasonable approximation of the effect of converting the results at the exchange rates in effect on the dates of the transactions, in which case those exchange rates are used).

(iv)     The resulting exchange differences, the cumulative translation of foreign currency, are recognized as other comprehensive income.

Goodwill and fair value adjustments arising on the acquisition date of a foreign operation to measure them at fair value are recognized as assets and liabilities of the foreign entity and converted at the closing exchange rate.

Considerations in the acquisition of businesses based on IFRS 3 "Business Combinations"

In accordance with International Financial Reporting Standard 3 "Business Combinations" (IFRS 3), the acquisition is considered a business combination and must be recorded by distributing the total assets acquired, including intangible assets and liabilities assumed, based on the fair values determined at the acquisition date. The excess of the acquisition cost over the net fair values of the assets acquired and liabilities assumed shall be recorded as goodwill.

The fair value of accounts and documents receivable considered in business combinations is usually similar to their contractual value, and the amounts are not expected to raise recoverability issues.

Liabilities must be determined at their fair value on the date of the business combination, mainly the valuation of bank loans and liabilities for obligations to the concessionaire.

It is recommended that this analysis be read in conjunction with ASUR's Annual Report for the year ended December 31, 2024.

Independent practitioner’s assurance report on the Compilation on the Condensed Consolidated Combined Pro Forma Financial Information Included in a Prospectus

To the Stockholders’ Meeting of

Grupo Aeroportuario del Sureste, S. A. B. de C. V.

We have completed our assurance engagement to report on the compilation of the condensed consolidated combined pro forma financial information of Grupo Aeroportuario del Sureste, S. A. B. de C. V. and subsidiaries (the “Company”) prepared by and under the responsibility of the Company’s Management. The condensed consolidated combined pro forma financial information consists of condensed consolidated combined pro forma statements of financial position as of September 30, 2025, and December 31, 2024, and the condensed consolidated combined pro forma statements of income for the nine-month period ended September 30, 2025, and for the year ended December 31, 2024 and related notes which are included in the ‘Selected Financial Information’ section of the Information Statement for Corporate Restructuring (the “Information Prospectus”) to be submitted to the National Banking and Securities Commission (the “CNBV”). The applicable assumptions and criteria on the basis of which the Company’s Management has compiled the condensed consolidated combined pro forma financial information are specified in the General Provisions applicable to Issuers of Securities and other Participants in the Securities Regulation (the “Single Issuers Circular”) and described in Note 2.

The condensed consolidated combined pro forma financial information has been compiled by the Company’s Management to illustrate the impact of the transaction described in the Information Prospectus and in Note 1 on the condensed consolidated combined pro forma financial information, in the Company’s condensed consolidated combined statements of financial position as of September 30, 2025 and December 31, 2024, and in the condensed consolidated combined statements of income for the nine-month period ended September 30, 2025, and for the year ended December 31, 2024, respectively. The Company’s financial information that served as the basis for compiling the condensed consolidated combined pro forma financial information has been obtained by the Company’s Management from its unaudited condensed consolidated combined interim financial statements as of September 30, 2025, as well as from the audited consolidated combined financial statements as of December 31, 2024, prepared in accordance with International Accounting Standard 34 ‘Interim Financial Reporting’ and in accordance with International Financial Reporting Standards, respectively.

Management’s Responsibility for the Condensed Consolidated Combined Pro Forma Financial Information

The Company’s Management is responsible for compiling the condensed consolidated combined pro forma financial information on the basis of the assumptions and criteria described in Note 2.

We have complied with the independence requirements and other ethical requirements of the International Code of Ethics for Professional Accountants (including International Independence Standards) issued by the International Ethics Standards Board for Accountants (IESBA Code), which is based on the fundamental principles of integrity, objectivity, professional competence and due care, confidentiality, and professional behavior.

Practitioner's Responsibilities

Our responsibility is to express an opinion, as required by Annex P ‘Instructions for preparing the information statement in case of corporate restructurings’ of the Single Issuers Circular, about whether the condensed consolidated combined pro forma financial information has been compiled, in all material respects, by the Company’s Management on the basis of the applicable assumptions and criteria.

We conducted our engagement in accordance with International Standard on Assurance Engagements (ISAE) 3420, Assurance Engagements to Report on the Compilation of Pro Forma Financial Information Included in a Prospectus, issued by the International Auditing and Assurance Standards Board. This standard requires that the practitioner comply with ethical requirements and plan and perform procedures to obtain reasonable assurance about whether the Company’s Management has compiled, in all material respects, the pro forma financial information on the basis of the applicable assumptions and criteria.

For purposes of this engagement, we are not responsible for updating or reissuing any reports or opinions on any historical financial information used in compiling the condensed consolidated combined pro forma financial information, nor have we, in the course of this engagement, performed an audit or review of the financial information used in compiling the condensed consolidated combined pro forma financial information.

The purpose of condensed consolidated combined pro forma financial information included in a prospectus is solely to illustrate the impact of a significant event or transaction on unadjusted financial information of the entity as if the event had occurred or the transaction had been undertaken at an earlier date selected for purposes of the illustration. Accordingly, we do not provide any assurance that the actual outcome of the event or transaction as of September 30, 2025, and December 31, 2024, and for the nine-month period ended September 30, 2025, and for the year ended December 31, 2024, would have been as presented.

An assurance engagement to report whether the pro forma financial information has been compiled, in all material respects, on the basis of the applicable assumptions and criteria, involves applying procedures to evaluate whether the assumptions and criteria used by the Company’s Management provide a reasonable basis for presenting the significant effects attributable to an event or transaction as if it had occurred at an earlier date, and to obtain sufficient and appropriate evidence as to whether:

The related pro forma adjustments give appropriate effect to those assumptions and criteria; and

The condensed consolidated combined pro forma financial information reflects the proper application of those adjustments to the unadjusted financial information.

The procedures selected depend on the practitioner's judgment, having regard to the practitioner's understanding of the nature of the company, the event or transaction in respect of which the condensed consolidated combined pro forma financial information has been compiled, and other relevant engagement circumstances.

The engagement also involves evaluating the overall presentation of the pro forma financial information.

We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

In issuing this opinion, we do not accept or assume responsibility for any other purpose or to any person other than the Company who has access to this report, unless expressly agreed with our prior written consent.

Note 2 - Basis for preparing the proforma Condensed Consolidated Combined Financial Information:

The Company’s pro forma condensed combined consolidated financial information as of September 30, 2025 and December 31, 2024, and the proforma condensed combined consolidated statements of comprehensive income for the nine-month period and for the year then ended (the “Proforma Condensed Combined Consolidated Financial Information”) is intended to reflect the terms and conditions set forth in the preliminary agreement for the acquisition of 100% of the capital and business of CPC Aeroportos, and to present the impact that the transactions carried out by those entities would have had on ASUR’s combined consolidated financial position and combined consolidated results, or on the application of accounting policies, criteria, or practices, as if those transactions had taken effect as of September 30, 2025, and December 31, 2024, for purposes of the combined consolidated statement of financial position, and as of January 1, 2025, and 2024, for purposes of the combined consolidated statement of comprehensive income of the combined consolidated statement of comprehensive income.

The figures included in the Proforma Condensed Combined Consolidated Financial Information in the column, “CPC Aeroportos,” include the combined financial information of CPC Aeroportos. The “Proforma Adjustments” columns, explained below, include the adjustments and assumptions applied to show the financial position as if the transaction had taken place on the dates described above. The figures included in the “Proforma Balances” column of the pro forma condensed consolidated combined financial information represent the simple sum of the “ASUR,” “CPC Aeroportos,” and “Proforma Adjustments” columns.

The not audited Condensed Proforma Combined Consolidated Financial Information of ASUR included herein should be read in conjunction with the audited annual consolidated financial statements as of December 31, 2024, prepared in accordance with International Financial Reporting Standards (IFRS), as well as its unaudited condensed interim financial information as of September 30, 2025, prepared in accordance with International Accounting Standard 34 (IAS 34) “Interim Financial Reporting”.

Base figures

The proforma condensed consolidated combined financial information has been compiled by ASUR's Management to illustrate the effects of the corporate restructuring that would have been had on ASUR's consolidated combined statements of financial position as of September 30, 2025 and December 31, 2024 and on its consolidated combined results for the nine-month period ended September 30, 2025 and the year ended December 31, 2024, respectively, assuming that the Transaction would have been carried out on September 30, 2025 and December 31, 2024, as well as on January 1, 2025 and 2024.

The financial information included in the “CPC Aeroportos” column has been obtained from the Company and prepared by its respective Management in accordance with IFRS accounting standards as adopted in Brazil, Ecuador, Costa Rica, and Curaçao. This proforma condensed consolidated combined financial information does not include any adjustments that may exist between these standards and IFRS accounting standards. The financial information for CPC Aeroportos has been converted to Mexican pesos using the exchange rate of Brazilian reais to Mexican pesos.

Notes to the Condensed Consolidated Combined Proforma Financial Information as of September 30, 2025 and December 31, 2024

In the proforma condensed consolidated combined financial information, certain reclassifications have been made with respect to the original presentation used in the not audited financial statements as of September 30, 2025, and in the audited financial statements as of December 31, 2024, of ASUR; as well as in the not audited financial information of CPC Aeroportos presented in the “CPC Aeroportos” column. However, there may be differences between ASUR's current accounting policies under IFRS and the not audited financial information of CPC Aeroportos that are not included in this proforma condensed consolidated combined financial information.

The proforma condensed consolidated combined financial information included is for illustrative purposes only and does not represent the actual consolidated combined operating results that would have been achieved had the transaction been completed on the assumed dates, nor is it intended to project ASUR's future consolidated combined operating results or financial position.

To present the effects of the acquisition of net assets on ASUR's pro forma financial statements, certain proforma adjustments and assumptions were applied to CPC Aeroportos' historical figures. From the date on which the Company acquires control of CPC Aeroportos' net assets, it will be the legal and accounting acquirer and will recognize the transaction as a business acquisition, applying the requirements of IFRS 3 "Business Combinations" in its financial statements.

The accounting treatment of the transaction will be carried out in due course in accordance with IFRS 3, which requires recognizing business acquisitions using the acquisition method. This method generally includes the following procedures and assessments: (i) determining whether a transaction or event qualifies as a business combination, (ii) identifying the acquirer (determining the company that obtains control of another business), (iii) determining the acquisition date, (iv) measuring and recognizing at fair value at the acquisition date the identified assets acquired, the liabilities assumed, and the non-controlling interest in the acquiree, (v) measuring the consideration at its fair value, and (vi) recognizing any difference between the consideration transferred and the net identifiable assets acquired, commonly known as acquired goodwill (asset) or gain on acquisition (profit or loss).

The Company interprets the consolidation of a controlled entity, as defined by IFRS 10, Consolidated Financial Statements, as occurring when the parent entity exercises control over the financial and operating policies of the controlled entity. This influence, or control, is manifested through the power of the controlling entity to make relevant decisions, within the framework defined in the business purchase contracts and the agreements contained therein, and which will definitively affect the performance and economic benefits of the controlled entity.

Proforma Adjustments and Assumptions

Notes to the Condensed Consolidated Combined Proforma Financial Information as of September 30, 2025 and December 31, 2024

As a result of the proposed transaction, the Company's shareholders will acquire control of CPC Aeroportos, and the transaction will be accounted for as a business acquisition in accordance with IFRS 3, whereby the Company would acquire the net assets of CPC Aeroportos. For the purposes of the proforma consolidated combined statement of financial position, management has considered the carrying amounts of the net assets acquired as of September 30, 2025, and December 31, 2024, as described below:

	As of September 30, 2025			As of December 31, 2024
Intangible assets, airport concessions - Net	$	37,913,690		$	37,632,249
Bank loans		(24,153,058	)		(22,817,937	)
Obligations with the concession grantor		(10,325,781	)		(9,272,420	)
Deferred income tax		2,834,209			2,657,411
Working capital		3,984,773			1,915,707
Other assets		190,801			381,761

Net assets acquired		10,444,635			10,496,771
Less: Purchase price		17,160,811			19,455,883

Goodwill	$	6,716,177		$	8,959,112

The company will acquire a credit line (loan) from JP Morgan for USD$1,299,000, which, at the closing exchange rate of 18.3342 on September 30, 2025, represents $23,816,126 pesos, and at the closing exchange rate of 20.7862 on December 31, 2024, represents $27,001,274 pesos. This loan will be used to finance the acquisition of 100% of the controlling stake in CPC Aeroportos for USD$936,000 which, at the closing exchange rate of 18.3342 on September 30, 2025, represents $17,160,811 pesos, and at the closing exchange rate of 20.7862 on December 31, 2024, represents $19,455,883 pesos.

This adjustment reflects the preliminary consideration and allocation of the purchase price based on the carrying amount of the net assets acquired, as well as the cash payment of the purchase price and the loan to be assumed upon closing of the transaction, which were to be made in accordance with the Purchase Agreement.

For the purposes of these proforma consolidated combined financial statements, ASUR recorded the net assets acquired and the liabilities assumed in the transaction at their carrying amounts. However, once the transaction is completed, ASUR will determine the fair value of all net assets acquired in order to adjust the transaction within the measurement period, that is, no later than twelve months after the acquisition date. The calculation and allocation of the purchase price will be based on the fair values of the net assets acquired at the final acquisition date of the controlling interest of 100% of the capital in CPC Aeroportos. Consequently, the actual amounts of each of the acquired assets and liabilities, as well as the goodwill, will differ from these pro forma amounts, and the difference could be significant.

The equity balances of CPC Aeroportos as of September 30, 2025 and December 31, 2024 will be eliminated as a result of the acquisition.

Notes to the Condensed Consolidated Combined Proforma Financial Information as of September 30, 2025 and December 31, 2024

The credit line (loan) obtained from JP Morgan for USD$1,299,000, assumed to be long-term, would pay an estimated interest of USD$34,200 corresponding to the estimated Term SOFR rate of 3.51%, which, at the closing exchange rate of 18.3342 on September 30, 2025, represents $627,000 Mexican pesos for the nine-month period ending on that date, and $947,800 Mexican pesos for the year ending December 31, 2024, at an exchange rate of 20.7862.

As of the transaction date, the identified tax effects are insignificant in the context of the pro forma adjustments and were therefore not included.

The completion of the aforementioned transactions is subject to approval by the ASUR Shareholders' Meeting.
