For Immediate Release

ASUR 2Q16 PASSENGER TRAFFIC UP 5.38% YOY

México D.F., July 20, 2016, Grupo Aeroportuario del Sureste, S.A.B. de C.V. (NYSE: ASR; BMV: ASUR), (ASUR) the first privatized airport group in Mexico and operator of Cancún Airport and eight other airports in southeast Mexico, as well as a 50% JV partner in Aerostar Airport Holdings, LLC, operator of the Luis Muñoz Marín International Airport in San Juan, Puerto Rico, today announced results for the three- and six-month periods ended June 30, 2016.

2Q16 Highlights1:

| · | EBITDA2 increased by 18.44% to Ps.1,337.51 million

| · | Total passenger traffic was up 5.38%

| · | Total revenues increased by 5.82%, reflecting increases of 12.04% in aeronautical revenues and 24.17% in non-aeronautical revenues, and were partially offset by the 27.25% decline in construction services revenues

| · | Commercial revenues per passenger increased by 18.86% to Ps.97.18

| · | Operating profit increased by 19.13%

| · | EBITDA margin was 59.61% compared with 53.26% in 2Q15

· Adjusted EBITDA margin3, excluding the effect of IFRIC12, was 71.83% compared with 70.76% in 2Q15

| 1. | Unless otherwise stated, all financial figures discussed in this announcement are unaudited, prepared in accordance with International Financial Reporting Standards (IFRS) and represent comparisons between the three- and six-month periods ended June 30, 2016, and the equivalent three- and six-month periods ended June 30, 2015. Results are expressed in pesos. Tables state figures in thousands of pesos, unless otherwise noted. Passenger figures exclude transit and general aviation passengers. Commercial revenues include revenues from non-permanent ground transportation and parking lots. All U.S. dollar figures are calculated at the exchange rate of US$1.00 = Ps. 18.4646.

| 2. | 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.

| 3. | Adjusted EBITDA Margin excludes the effect of IFRIC12 with respect to the construction or improvements to concessioned assets, as explained in page 5 of this report. Adjusted EBITDA Margin is calculated by dividing EBITDA by total revenues less construction services revenues. 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.

Passenger Traffic

2Q16 total passenger traffic increased year-over-year by 5.38%, reflecting growth of 5.69% in domestic passenger traffic and 5.13% in international passenger traffic.

The 5.69% increase in domestic passenger traffic was driven by the majority of ASUR’s airports, with the exception of Minatitlan and Villahermosa where traffic declined by 7.44% and 9.48%, respectively.

The 5.13% growth in international passenger traffic resulted primarily from an increase of 5.94% in traffic at the Cancun airport.

Total passenger traffic for 6M16 increased by 7.15%, reflecting growth of 9.03% in domestic passenger traffic driven by the majority of ASUR’s airports, with the exception of Minatitlan and Villahermosa, which declined 4.81% and 5.55%, respectively. The 5.88% increase in international passenger traffic resulted primarily from a 6.46% increase at the Cancun airport.

Consolidated Results for 2Q16

Total revenues for 2Q16 rose 5.82% year-over-year to Ps.2,243.79 million, mainly due to increases of:

| · | 12.04% in revenues from aeronautical services, mainly as a result of the 5.38% increase in passenger traffic; and

| · | 24.17% in revenues from non-aeronautical services, principally reflecting the 25.29% increase in commercial revenues detailed below.

These increases were partially offset by the 27.25% decline in revenues from construction services that resulted from lower capital expenditures and other investments in concessioned assets during the period.

ASUR classifies commercial revenues as those derived from the following activities: duty-free stores, car rentals, retail operations, banking and currency exchange services, advertising, teleservices, non-permanent ground transportation, food and beverage operations, and parking lot fees.

Commercial revenues rose 25.29% year-over-year in 2Q16, principally due to a 5.38% increase in total passenger traffic. There were increases in revenues from the following activities, partially offset by the 7.66% decline in advertising revenues:

| · | 27.24% in retail operations;

| · | 34.24% in food and beverage operations;

| · | 18.43% in duty free;

| · | 48.73% in other revenue;

Total Passengers (‘000) | 6,626 | 6,984 | 5.41
Total Commercial Revenues | 541,689 | 678,702 | 25.29
Commercial revenues from direct operations (1) | 101,739 | 120,369 | 18.31

Commercial revenue from direct operations per passenger (1) | 15.36 | 17.23 | 12.17
Commercial revenue per passenger (excluding direct operations) | 66.40 | 79.95 | 20.41

Note: For purposes of this table, approximately 45,500 and 49,800 transit and general aviation passengers are included in 2Q15 and 2Q16, respectively.

| (1) | Revenues from direct commercial operations represent ASUR’s operation of convenience stores in airports, as well as the direct sale of advertising space through April 30, 2015, when advertising sales were concessioned to a third party.

ASUR 2Q16, Page 4 of 18

Construction revenues and expenses: 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. During 2Q16, ASUR recognized Ps.381.66 million in revenues from “Construction Revenues,” a year-on-year decline of 27.25%, due to lower capital expenditures and fewer investments in concessioned assets. 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, as the increase in revenues that relates to Construction Revenues does not result in a corresponding increase in EBITDA.

As a result, 2Q16 EBITDA Margin was 59.61% compared with 53.26% in 2Q15. Adjusted EBITDA Margin, however, which excludes the effect of IFRIC 12 with respect to the construction or improvements to concessioned assets, was 71.83% in 2Q16 compared with 70.76% in 2Q15.

Total operating costs and expenses for 2Q16 declined 6.36% year-over-year. The 27.25% decline in construction costs resulting from lower capital expenditures and fewer investments in concessioned assets during the period more than offset the following cost increases:

| · | 11.01% in cost of services, mainly due to the Terminal 3 expansion and higher software license fees. The higher cost of sales from convenience stores directly operated by ASUR also contributed to this increase;

· 18.45% in the technical assistance fee paid to ITA, resulting from the increase in EBITDA for the quarter (a factor in the calculation of the fee);

| · | 16.63% in concession fees paid to the Mexican government, mainly due to an increase in regulated revenues (a factor in the calculation of the fee);

| · | 12.44% in depreciation and amortization, resulting mainly from capitalized investments; and

| · | 7.27% in administrative expenses, principally reflecting higher travel expenses and professional fees.

Excluding construction costs, operating costs and expenses rose 12.45% to Ps.655.52 million.

| 2Q15 | 2Q16 | % Change
Cost of Services | 287,745 | 319,435 | 11.01

Construction Costs | 524,624 | 381,658 | (27.25)
TOTAL | 1,107,578 | 1,037,177 | (6.36)

Operating margin for the quarter was 53.78% compared with 47.77% in 2Q15, reflecting the 5.82% increase in revenues along with the 6.36% decline in expenses.

Adjusted operating margin, which excludes the effect of IFRIC 12 with respect to the construction or improvements to concessioned assets, and is calculated as operating profit divided by total revenues less construction services revenues, was 64.80% in 2Q16 compared with 63.47% in 2Q15.

Comprehensive Financing Gain (Loss) for 2Q16 was a Ps.11.27 million loss, compared to a Ps.16.60 million loss in 2Q15. Interest expenses rose by Ps.5.05 million during the period, mainly due to the increase in interest rates. Interest income increased by Ps.7.44 million.

Furthermore, ASUR reported a foreign exchange loss of Ps.27.56 million in 2Q16, reflecting a 4.53% quarterly depreciation of the Mexican peso against the U.S. dollar on ASUR’s lower foreign currency net liability position. This compared to a Ps.30.50 million loss in 2Q15 resulting from the 1.41% quarterly average Mexican peso depreciation during that period.

Table VI: Comprehensive Financing Result (Cost)

| 2Q15 | 2Q16 | Change | % Change |
Interest income | 38,187 | 45,627 | 7,440 | 19.48 |
Interest expenses | (24,293) | (29,341) | (5,048) | 20.78 |
Foreign exchange gain (loss), net | (30,496) | (27,559) | 2,937 | (9.63) |
Total | (16,602) | (11,273) | 5,329 | (32.10) |

In addition, in 2Q16, ASUR recognized a Ps.143.16 million gain in stockholders’ equity resulting from the translation effect of Aerostar’s financial statements (which are denominated in U.S. dollars), relating to the valuation of the stockholders’ equity derived from the 7.05% depreciation of the peso against the U.S. dollar, between the close of 2Q16 and the close of 1Q16.

ASUR 2Q16, Page 6 of 18

Income (Loss) from Equity Investment in Joint Venture. During 2Q16, our equity in the income of Aerostar, our joint venture with Highstar Capital IV and its affiliated funds, was a net gain of Ps.58.17 million. In addition, ASUR recorded a Ps.143.16 million gain in stockholders’ equity resulting from the translation effect of Aerostar’s financial statements (which are denominated in U.S. dollars), relating to the valuation of the shareholders’ equity derived from the 7.05% depreciation of the peso against the U.S. dollar, between the close of 1Q16 and the close of 2Q16. In 2Q15, ASUR reported a net gain of Ps.21.68 million from our equity in the income of Aerostar and a Ps.11.41 million gain in stockholders’ equity resulting from the translation effect of Aerostar’s financial statements relating to the valuation of the shareholders’ equity derived from the depreciation of the peso against the U.S. dollar.

During 2Q16, total passenger traffic at SJU airport increased 4.31% to 2,304,464 from 2,209,207 in 2Q15.

Income Taxes for 2Q16 increased by Ps.101.85 million year-over-year, principally due to the following factors:

| · | A Ps.91.29 million increase in the provision for income taxes, reflecting a higher taxable income base at the Veracruz and Cancun airports, as well as at Cancun Airport Services; and taxable income at Huatulco airport.

| · | A Ps.11.78 million increase in deferred income taxes largely reflecting the recognition of the effects of the 0.65% decline in inflation during 2Q16 on the fiscal tax balance.

Net income for 2Q16 increased by 18.25% to Ps.866.62 million, up from Ps.732.90 million in 2Q15. Earnings per common share for the quarter were Ps. 2.8887 and earnings per ADS (EPADS) were US$1.5645 (one ADS represents ten series B common shares). This compares with earnings per share of Ps.2.4430 and EPADS of US$1.3231 for the same period last year. The higher net income principally reflects the 5.38% increase in passenger traffic. During 2Q16, ASUR reported a Ps.58.17 million gain corresponding to its participation in Aerostar, the joint venture to operate SJU airport, compared to a gain of Ps.21.68 million in 2Q15.

Consolidated Results for 6M16

Total revenues for 6M16 increased year-over-year by 10.32% to Ps.4,321.14 million, mainly due to the following increases:

| · | 13.73% in revenues from aeronautical services as a result of the 7.15% increase in passenger traffic during the period; and

| · | 26.55% in revenues from non-aeronautical services, mainly due to the 28.17% increase in commercial revenues detailed below.

These increases were partially offset by the 26.89% decline in construction services due to lower capital investments made during the period.

Commercial revenues for 6M16 rose by 28.17% year-over-year, principally due to revenue increases in the following areas:

· 29.29% in retail operations;

· 25.22% in duty-free stores;

· 24.91% in food and beverage operations;

· 58.35% in car rentals;

ASUR 2Q16, Page 8 of 18

* For purposes of this table, approximately 103,000 and 110,500 transit and general aviation passengers are included for 6M15 and 6M16, respectively.

| (1) | Revenues from direct commercial operations represent ASUR’s operation of convenience stores in airports, as well as the direct sale of advertising space until April 30, 2015, when advertising sales were concessioned to a third party.

Total operating costs and expenses for 6M16 declined by 2.58% year-over-year, primarily due to the 26.89% reduction in construction costs resulting from lower capital expenditures and fewer investments in concessioned assets during the period, which more than offset the following cost increases:

| · | 10.90% in cost of services, principally due to the Terminal 3 expansion, higher software license and professional fees, as well as increased office leases, security and maintenance expenses. The increase in cost of sales from the convenience stores directly operated by ASUR also contributed to this increase;

| · | 18.10% in concession fees paid to the Mexican government, mainly due to an increase in regulated revenues (a factor in the calculation of the fee);

ASUR 2Q16, Page 9 of 18

· 21.14% in technical assistance costs, reflecting the corresponding increase in EBITDA during the period;

| · | 11.70% in depreciation and amortization, resulting mainly from higher capitalized investments; and

· 4.66% in administrative expenses, principally reflecting higher professional fees, travel and security expenses.

Excluding construction costs, operating costs and expenses rose 12.49% to Ps.1,303.43 million.
