Bulletin – Company Restructuring

Airplan

Airplan holds concessions to operate the following airports in Colombia: Enrique Olaya Herrera Airport and José Maria Córdova International Airport in Medellin, Los Garzones Airport in Montería, Antonio Roldan Betancourt Airport in Carepa, El Caraño Airport in Quibdó, and Las Brujas Airport in Corozal.

Not all the necessary regulatory approvals have yet been received to conclude the acquisition of Oriente.

In light of the pending regulatory approvals for the acquisition of Oriente, the sellers and ASUR have agreed to make commercially reasonable efforts to obtain the pending approvals and, if successful, to negotiate in good faith an adjustment to the purchase price.

Oriente holds concessions to operate the following airports in Colombia: Simón Bolívar International Airport in Santa Marta, Almirante Padilla Airport in Riohacha, Alfonso López Pumarejo Airport in Valledupar, Camilo Daza International Airport in Cúcuta, Palonegro International Airport in Bucaramanga, and Yariguíes Airport in Barrancabermeja. If it is possible to conclude this acquisition, ASUR will own approximately 97.26% of the capital stock of Oriente.

In the event that (i) the required regulatory approvals for the acquisition of Oriente are obtained, (ii) the sellers and ASUR reach an agreement regarding the purchase price, and (iii) the acquisition of Oriente is concluded, ASUR will issue the relevant information to its stockholders and the general public in compliance with its reporting obligations under the applicable legal provisions.

Based on the foregoing, this company restructuring information bulletin and the pro forma financial information refer only to the conclusion of the Transaction relating to Airplan.

The stockholders of ASUR and the general public are hereby informed that, after having obtained all the necessary approvals for the conclusion of the Acquisition of Airplan and complied with all the conditions to which the Transaction was subject, on October 19^th, 2017 ASUR paid the amount of the purchase price for the stake in Airplan in full, thereby concluding the Transaction.

The full amount paid by ASUR for the acquisition of Airplan was approximately $3.774 billion pesos ($204 million U.S. dollars at the exchange rate of $18.5 pesos per dollar valid on October 18^th, 2017) (the “Total Sum of the Transaction”).

The funds for payment of the purchase price were obtained from a credit contracted with BBVA Bancomer, S.A., Institución de Banca Múltiple, Grupo Financiero BBVA Bancomer, as described below in this Information Bulletin.

The Acquisition is an important strategic addition to allow ASUR to enter the South American market by offering airport services through six airports in Colombia. The operation of these airports will considerably extend the scope and scale of the airport services provided by ASUR. Given that ASUR’s business is highly dependent on international tourism, the Acquisition will give ASUR the opportunity to serve 10.4 million additional passengers through Airplan. This investment also contributes to ASUR’s corporate objective of stimulating and promoting the development of air routes that satisfy the needs of passengers, airlines and ASUR’s own airports.

History and Background

ASUR was incorporated in 1998 as part of the Mexican federal government’s two-stage plan to open up the country’s airport system to private investment. Under the scheme established by the Ministry of Communications and Transport (Spanish initials, “SCT”), 35 of the 58 major public airports in Mexico were selected to form part of this program and were divided into four groups: the Southeast group (made up of the nine Mexican airports of ASUR), the Mexico City group (which currently contains a single airport), the Pacific group (which has 12 airports) and the Center-North group (with 13 airports). The first stage of the program consisted of selecting an investor for each airport group via a process of public tender. This investor was granted a stake of 15.0% in the airport group’s capital stock, as well as the right and the obligation to enter into a series of contracts, including one to provide certain technical assistance services in accordance with the terms established during the public bidding process. In the second stage of the program, all or part of the remaining shares in each airport group were offered for sale to the public.

In June 1998, the SCT granted concessions to the subsidiaries of ASUR for the administration, operation, development and, if applicable, construction of the Southeast Airports for a period of 50 years from November 1^st, 1998. In addition, a holding company was constituted for each airport group, which owns all of the shares (except one) in the capital stock of the concession-holding companies, and a service company was also established for each group.

For a more detailed description of the history and background of ASUR, please refer to the company’s Annual Report, which is available for consultation on the ASUR website www.asur.com.mx and on the website of the Mexican stock exchange www.bmv.com.mx.

Description of the Business

ASUR holds concessions to operate, maintain and develop nine airports in the southeast region of Mexico for a period of 50 years from November 1^st, 1998. As the operator of these airports, ASUR receives revenues from fees charged to airlines, passengers, and other parties for the use of the airport facilities belonging to the company. ASUR also receives revenues from other activities that take place in its airports, such as the lease of space for restaurants and other businesses. The concessions held by ASUR include that of Cancún International Airport, which was the second-busiest airport in Mexico in 2016 in terms of passenger traffic, and the busiest in terms of international passenger traffic on scheduled flights, according to information provided by Mexico’s Civil Aeronautical Department (Spanish initials “DGAC”), which is the federal authority that oversees the Mexican aviation industry. ASUR also holds the concessions to operate airports in Cozumel, Huatulco, Mérida, Minatitlán, Oaxaca, Tapachula, Veracruz and Villahermosa.

ASUR has an indirect stake of 60.0% in the company Aerostar: through its subsidiary Aeropuerto de Cancún, S.A. de C.V., it has a lease agreement that allows it to operate, maintain and develop Luis Muñoz Marín Airport located in San Juan, Puerto Rico, for a period of 40 years from February 27^th, 2013.

A third-party buyer, Public Sector Pension Investment Board, has acquired the remaining 40% of the shares in Aerostar. This represents a combined investment of USD 430 million. The transaction has received all of the required regulatory approvals. ASUR expects to consolidate the results of Aerostar in its financial statements.

Through its subsidiary Aeropuerto de Cancún, S.A. de C.V., ASUR has begun construction of Terminal 4 at Cancún International Airport, in accordance with the corresponding master development program. The new terminal is located to the west of the existing airport facilities, between Runways 12L and 12R. The terminal building will initially have a surface area of more than 64,000 square meters, as well as 10 passenger-inspection points and 12 aircraft parking stands, each with its own passenger-boarding bridge. The terminal was designed to be easily expandable when capacity increases are required, without causing disruption for day-to-day operations, and will maintain separate flows for domestic and international passengers. The terminal will also be divided into separate levels, with the upper level reserved for departing passengers and the mezzanine and lower levels for arriving passengers. It is expected that Terminal 4 will begin operating during the fourth quarter of 2017.

On March 13^th, 2008, and as a result of this tender, Aerocivil and the Olaya Herrera Airport Public Authority (“AOH”) granted Concession Agreement number 8000011-OK (the “Airplan Concession”) to the company Airplan, in order for the latter on its own behalf and under its own risk to perform the administration, operation, commercial development, remodeling, maintenance and modernization of the following airports: (i) Olaya Herrera; (ii) José María Córdova; (iii) El Caraño; (iv) Los Garzones; (v) Antonio Roldán Betancourt; and (vi) Las Brujas, all of which were under the control of and supervised by Aerocivil and AOH (the “Airplan Project”).

Under the concession agreement in question, Aerocivil permitted Airplan to use the fixed and moveable assets that form part of the Airplan Concession (which do not include those intended for air-traffic control, radio navigational aids or aviation safety). Aerocivil also ceded the corresponding rights to receive (i) revenues from the services specified by Aerocivil in its administrative resolutions, which must be provided by Airplan in the performance of its duties under the Airplan Concession; and (ii) revenues different to those specified by Aerocivil, received by Airplan in the performance of its duties under the Airplan Concession, on the understanding that a fee would be applicable to such revenues equivalent to 19% of Airplan’s gross income.

The development of the Airplan Concession is envisaged in three stages: (i) an initial stage lasting 10 months; (ii) a stage of remodeling and modernization lasting 60 months; and (iii) a maintenance stage. The Airplan Concession will last until the date on which any of the following events first occurs: (a) the revenues specified by Aerocivil are equal to expected revenues, provided that a period of at least 15 years has elapsed since the date on which the Airplan Concession came into force; or (b) a period of 25 years has elapsed since the date on which the Airplan Concession came into force, as applicable.

Airplan must comply with a series of obligations set forth in the Airplan Concession. These include: providing a compliance guarantee and a civil liability guarantee; paying a success fee for the transaction; paying the concession fee; refraining from providing air-transport services to passengers; refraining from allowing Colombian state-owned entities to hold stakes of more than 50% in the company’s capital stock; complying with the applicable environmental legislation; providing the relevant services to airport users in accordance with the technical specifications established in the Airplan Concession and in the agreements transferred;

creating and maintaining a trust agreement (the assets held in trust must include all gross income received as revenue from the Airplan Concession, as well as any debt or capital resources obtained to execute the Airplan Concession); and carrying out any procedures and taking any measures, whether technical or financial, that are necessary to accomplish the Airplan Project. Aerocivil and AOH have the obligation to: issue notifications and transfer the contracts ceded for activities to be carried out in the areas under concession; recognize expenses that require compensation or the replacement of assets damaged due to force majeure, when the risk is assumed by Aerocivil; make payments arising from complementary works; pay differences for compensation; and make any notifications or take any measures necessary to allow the implementation of the Airplan Project. In the event that any instance of non-compliance with any of the important provisions of the Airplan Concession takes place and is not remedied, Aerocivil may rescind the concession and apply a contractual penalty of up to USD 20,000,000.00 (twenty million dollars, zero cents, legal tender of the United States of America). This sum may be reduced depending on what stage the Airplan Project is in when the breach of terms occurs.

An auditor is entrusted with coordinating and overseeing the execution of the Airplan Concession. This person is authorized to give instructions to Airplan regarding obligatory compliance aspects, and to request any information considered necessary to verify compliance with the obligations under the Airplan Concession. Finally, Airplan and its stockholders have the obligation not to assign in any way their stakes in the Airplan Concession without prior written authorization from AOH and Aerocivil, in the understanding that if any such assignment is carried out, the assignees must be persons that satisfy similar or superior conditions in terms of experience and financial capacity in accordance the provisions of the Airplan Tender.

Airplan has reached an agreement regarding investment commitments with the Colombian government in each of its airports. In 2017 and 2018, José María Córdova International Airport in Medellin has committed investments of 94.794 billion Colombian pesos and 43.688 billion Colombian pesos, respectively. In 2017, Enrique Olaya Herrera Airport in Medellin has committed investments of 441 million Colombian pesos.

Antonio Roldán Betancourt Airport in Carepa and Las Brujas Airport in Corozal do not have any investment commitments with the Colombian government for 2017 and 2018.

4. RISK FACTORS

The Issuer has identified the following risk factors in relation to the Transaction that might have a significant effect on its performance and profitability, and could influence the price of its shares. The possibility exists that ASUR’s operations might be affected by other risks that the Issuer has not foreseen or does not consider significant at this time.

Risk Factors Relating to the Issuer

For more detailed information about the risk factors relating to the Issuer, please refer to the company’s Annual Report, which is available for consultation on the ASUR website www.asur.com.mx and on the website of the Mexican Stock Exchange www.bmv.com.mx.

Risk Factors Relating to the Transaction

The pro forma unaudited consolidated financial statements presented are not indicative of future results.

The pro forma unaudited consolidated financial statements included in this Information Bulletin are presented for illustrative purposes only and do not reflect the operating results, financial position or real cash flows that would have been recorded had the Transaction been carried out on the supposed dates, nor do they project the future operating results or financial position of ASUR.

The pro forma unaudited consolidated financial statements included in this Information Bulletin should be read in conjunction with the historical financial statements of ASUR and the notes attached thereto.

ASUR will incur debt to conclude the Transaction.

ASUR will incur debt to pay for all of the Total Sum of the Transaction, which may result in a significant increase in interest-payment costs. Furthermore, the respective credit agreement will contain a series of restrictions, such as limits on dividend payments under certain circumstances, restrictions on incurring additional debt under certain circumstances, and additional financial restrictions. Consequently, the capacity of ASUR to finance future acquisitions, expansions, capital expenditure and operating costs may be significantly limited. ASUR may also refinance the debt assumed in relation to the Transaction. The ability of ASUR to refinance said debt under favorable terms and conditions depends on several factors that are beyond the control of ASUR, including market conditions and the availability of resources.

ASUR may not be capable of integrating the businesses acquired in the Transaction.

A key element in materializing the benefits expected from the Transaction is the capacity to integrate the operations of Airplan into ASUR’s current operating model in a way that is timely and effective. It cannot be guaranteed that these efforts will be successful or will be completed as ASUR expects. If this is not the case, the operations, financial position and results of ASUR may be significantly and adversely affected.

Adverse economic conditions in Colombia could negatively affect our financial situation and operating results.

As a result of the Transaction, ASUR will be subject to any political, economic, legal or fiscal risks in Colombia, which may include general economic conditions in Colombia, possible devaluations of the Colombian peso against other currencies (including the U.S. dollar), inflation, interest rates, regulation (including legislation on such matters as economic competition, communications, transport and foreign investment), taxes, expropriations, social unrest, crime rates and other political, social and economic factors over which ASUR has no control.

In the past, Colombia has experienced prolonged periods of economic crisis caused by internal and external factors over which ASUR has no control. These periods have been characterized by instability in currency exchange rates, high inflation, economic recession, reductions in international capital investments, reductions in the liquidity of

Grupo Aeroportuario del Sureste – Colombia

Bulletin – Company Restructuring

Airplan

the banking sector, and high levels of unemployment. Conditions such as these may occur again repeatedly in the future and may negatively affect the business, the financial situation or the operating results of ASUR.

Airplan may require greater investments in assets and have higher operating costs.

As a result of the acquisition of Airplan, ASUR may need to make investments in assets and incur operating costs that might be significantly higher than its historical investments and costs, which might adversely affect ASUR’s operating results.

The Transaction could have an effect on ASUR’s share price.

Investors might perceive the Transaction negatively, which may have repercussions for the price of ASUR’s shares on the markets.

Mexico City, October 19, 2017

To the Stockholders of

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

We have concluded our work on the compilation of pro forma condensed consolidated 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. Said pro forma condensed consolidated financial information consists of the pro forma condensed consolidated statements of financial position at June 30, 2017 and December 31, 2016, and the pro forma condensed consolidated statements of income for the six-month period ended on June 30, 2017 and for the year ended on December 31, 2016, as well as the related notes, which are included in the section on “Selected Financial Information” of the Statement of Corporate Restructuring Information (the “Informative Booklet”) to be submitted to the National Banking and Securities Commission in Mexico (CNBV). The assumptions and criteria applied by Company Management in gathering the pro forma condensed consolidated financial information are described in the General Provisions applicable to Issuers of Securities and other Participants in the Securities Market (the “Sole Circular of Issuers” or “Circular Única by its acronym in spanish”), described in Note 2.

The pro forma condensed consolidated financial information was gathered by Company Management to show the effects of the operation described in the Informative Booklet and in Note 1 to the pro forma condensed consolidated financial information, in the Company's condensed consolidated statements of financial position at June 30, 2017 and at December 31, 2016, and in the condensed consolidated statements of income for the six-month period ended on June 30, 2017 and for the year ended on December 31, 2016, respectively, assuming that said operation took place on the dates mentioned before. The Company’s financial information that served as the basis to gather the pro forma condensed consolidated financial information was obtained by Company Management from its unaudited condensed interim consolidated financial statements at June 30, 2017, as well as from its audited consolidated financial statements at December 31, 2016, prepared in accordance with International Accounting Standard 34 “Interim financial information” and the International Financial Reporting Standards (IFRS), respectively.

For the purpose of this engagement, we are not responsible for updating or reissuing reports or opinions on historical financial information used to gather pro forma condensed consolidated financial information, nor do we, in the course of this engagement, conduct an audit or review of the historical information used to gather the pro forma condensed consolidated financial information.

Management’s responsibility for the pro forma condensed consolidated financial information

Company Management is responsible for gathering pro forma condensed consolidated financial information in accordance with the assumptions and criteria described in Note 2.

Auditor’s responsibility

Our responsibility consists of expressing an opinion, based on our assurance work, as required by the Appendix P ‘Instructions for the preparation of information in case of corporate’s restructuring of the Sole Circular of Issuers, on whether the aforementioned pro forma consolidated condensed financial information has been gathered, in all material respects, in accordance with the provisions and criteria established by Company Management.

We conducted our work on the basis of International Standard on Assurance Engagements 3420 “Assurance Reports on the process to Compile Pro Forma Financial Information Included in a Prospectus”, issued by the International Auditing and Assurance Standards Board. That standard requires the independent public accountants to comply with ethical requirements, and to plan and develop procedures to obtain reasonable certainty about whether the Company’s Management has gathered, in all significant aspects, the pro forma condensed consolidated financial information and the criteria established by the Company’s Management.

The purpose behind the pro forma condensed consolidated financial information included in the Informative Booklet is solely to show the effects of a significant event or transaction on the Company’s historical financial information, as though the event had occurred or a transaction had been conducted on a previous date, determined for those purposes. Therefore, we offer no assurance that the actual results of the event or transaction at June 30, 2017 and December 31, 2016 and for the six-month period ended on June 30, 2017 and for the year ended December 31, 2016 were the same as those presented.

An assurance engagement to report whether pro forma financial information has been gathered, in all material respects, on the basis of the applicable assumptions and criteria involves applying procedures to determine if the assumptions and criteria applied by Company Management provide a reasonable basis to present the significant effects attributable to an event or a transaction, as though it had been conducted at a previous date, to obtain sufficient and proper information on whether:

• The effects of the pro forma adjustments were conducted in accordance with the established assumptions and criteria; and

• The pro forma condensed consolidated financial information reflects the proper application of adjustments to the financial information.

Page 2

The selected procedures depend on the auditors’ judgment, taking into account the auditors’ understanding of the Company’s nature, the event or transaction on which pro forma condensed consolidated financial information has been gathered, and other relevant circumstances.

Our work also included an evaluation of the general presentation of the pro forma condensed consolidated financial information.

We consider that the evidence obtained provides a sufficient and proper basis to support our opinion.

Opinion

In our opinion, the pro forma condensed consolidated financial information of Grupo Aeroportuario del Sureste, S. A. B. de C. V. and subsidiaries at June 30, 2017 and for the six-month period ended on that date, as well as at December 31, 2016 and for the year then ended, has been gathered, in all material respects, in accordance with the assumptions and criteria described in Note 2.

Grupo Aeroportuario del Sureste’s Information

Grupo Aeroportuario del Sureste, S. A. B. de C. V. (the Company or ASUR), through its subsidiaries, holds different concessions to operate, maintain and develop nine airports in the southeast of Mexico for a period of 50 years as of November 1, 1998. As the operators of those airports, they charge airlines, passengers and other users certain fees for the use of airport facilities. They also receive rent fees and other income from business activities conducted in the airports that they operate, such as leases of areas for restaurants and other businesses. ASUR concessions include a concession to operate the Cancun International Airport, which has recently become one of the busiest airports in Mexico in terms of passenger traffic, and the busiest in terms of international passengers under regular services, as determined by the General Civil Aeronautics Office, the Mexican federal body overseeing aviation matters. They also hold concessions to operate the Cozumel, Huatulco, Mérida, Minatitlán, Oaxaca, Tapachula, Veracruz and Villahermosa airports.

Additionally, ASUR indirectly holds 60.0% interest in Aerostar Airport Holdings, LLC (Aerostar) through its Cancun Airport subsidiary. Aerostar holds a lease agreement to operate, maintain and develop the Luis Muñoz Marín Airport in San Juan, Puerto Rico, for a forty-year period, starting on February 27, 2013.

Sociedad Operadora de Aeropuertos de Centro Norte, S. A. (Airplan)’s Information

Airplan was incorporated in 2008 as a licensee to hold and manage, operate, commercially exploit, adapt, modernize and provide maintenance to the airport terminals specified later on herein, as established in concession agreement no. 8000011OK dated March 13, 2008. In complying with the terms of the concession, Airplan and Fiduciaria Bancolombia set up a trust to manage the financial flows arising from the concession, including those in relation to debt contracts. Additionally, in general terms, as established in the concession, Airplan is required to sign a technical advice and assistance agreement with an entity specializing in airport operations. The agreement currently in place was signed with Capital Airports Holding Company.

Pro forma adjustments

In presenting the effects of the Acquisition of net assets in the pro forma financial statements of ASUR, certain pro forma adjustments were applied to the historical figures of Airplan. As from the date on which the Company acquires total control of the net assets of Airplan, it will recognize the transaction as a business acquisition, applying the provisions of IFRS “Business combination” (IFRS 3) to its financial information.

The accounting treatment to be accorded to the operation will be applied in accordance with the provisions of IFRS 3, which requires entities to recognize business acquisitions by the acquisition method, which in general terms includes the following procedures and evaluations (i) determine whether a transaction or event qualifies as a business combination, (ii) identify the purchaser (determine the company obtaining control over the other business), (iii) determine the date of acquisition, (iv) measure and recognize at fair value, on the acquisition date, the identified assets acquired, the liabilities assumed and the non-controlling interest in the acquired business, (v) measure the consideration at fair value, and (iv) recognize any differences between the price charged and the net identifiable assets acquired, which is usually known as goodwill acquired (asset) or gain on acquisition (income/loss).

The adjustments shown below have been calculated and estimated, where applicable, based on Airplan historical values. After the Operation concludes, those historical values will be modified to consider the fair values required by IFRS 3.

The adjustments to the pro forma condensed consolidated statements of financial position are reflected as though the Operation had occurred on June 30, 2017 and December 31, 2016, applying the USD-peso exchange rate and the Colombian peso-Mexican peso exchange rate. The exchange rates used to convert US dollars to Mexican pesos at the respective dates are $18.0626 pesos at June 30, 2017 and $20.664 pesos at December 31, 2016 per US dollar; additionally, the exchange rates used to convert Colombian pesos to Mexican pesos are $168.09 at June 30, 2017 and $152.92 pesos at December 31, 2016 per Mexican peso.
