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 twelve-month periods ended December 31, 2016, and the equivalent three- and twelve-month periods ended December 31, 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.20.6194

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

4Q16 total passenger traffic increased year-over-year by 11.91%, reflecting growth of 14.79% in domestic passenger traffic and 9.29% in international passenger traffic.

The 14.79% increase in domestic passenger traffic was driven by the majority of ASUR’s airports, with the exception of Cozumel and Minatitlán, where traffic declined by 0.55% and 16.19%, respectively.

The 9.29% growth in international passenger traffic resulted primarily from an increase of 9.44% in traffic at the Cancún airport.

Total passenger traffic for FY16 increased by 8.67%, reflecting growth of 10.86% in domestic passenger traffic driven by the majority of ASUR’s airports, with the exception of Minatitlán and Villahermosa, which declined 9.79% and 1.87%, respectively. The 6.90% increase in international passenger traffic resulted primarily from a 7.39% increase at the Cancún airport.

Consolidated Results for 4Q16

Total revenues for 4Q16 rose 5.90% year-over-year to Ps.3,076.59 million, principally due to increases of:

· 19.10% in revenues from aeronautical services, mainly as a result of the 11.91% increase in passenger traffic; and

· 21.66% in revenues from non-aeronautical services, principally reflecting the 21.41% increase in commercial revenues detailed below.

These increases were partially offset by the 11.35% 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 in the quarter rose 21.41% year-over-year, principally due to an 11.91% increase in total passenger traffic. There were increases in revenues from the following activities:

· 23.55% in retail operations;

· 13.86% in duty free;

· 40.43% in food and beverage operations;

· 32.34% in other revenue;

· 17.49% in car rental revenues;

· 8.23% in parking lot fees;

· 33.30% in banking and currency exchange services;

· 3.30% in ground transportation; and

· 52.32% in teleservices.

This was partially offset by a 6.68% decline in advertising revenues.

Note: For purposes of this table, approximately 54,600 and 50,000 transit and general aviation passengers are included in 4Q15 and 4Q16, respectively.

(1) Represents ASUR’s operation of convenience stores in airports.

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 4Q16, ASUR recognized Ps.1,163.52 million in revenues from “Construction Revenues,” a year-on-year decline of 11.35%, 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, 4Q16 EBITDA Margin was 43.55% compared to 38.77% in 4Q15. Adjusted EBITDA Margin, however, which excludes the effect of IFRIC 12 with respect to the construction or improvements to concessioned assets, was 70.04% in 4Q16 compared with 70.71% in 4Q15.

Total operating costs and expenses for 4Q16 declined 1.37% year-over-year. This was mainly the result of the 11.35% decline in construction costs resulting from lower capital expenditures and fewer investments in concessioned assets during the period, together with a 2.76% decline in administrative expenses principally reflecting lower professional fees. These declines more than offset the following cost increases:

· 28.91% in cost of services, mainly due to the Terminal 3 expansion and the higher cost of sales from convenience stores directly operated by ASUR;

·19.42% 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);

· 20.42% in concession fees paid to the Mexican government, mainly due to an increase in regulated revenues (a factor in the calculation of the fee); and

ASUR 4Q16, Page 5 of 18

· 13.75% in depreciation and amortization, resulting mainly from capitalized investments.

Excluding construction costs, operating costs and expenses rose 21.00% to Ps.708.70 million.

Table V: Operating Costs and Expenses for 4Q16

	4Q15	4Q16	% Change
Cost of Services	283,379	365,310	28.91
Administrative	52,161	50,722	(2.76)
Technical Assistance	59,282	70,793	19.42

Operating Costs and Expenses Excluding Construction Costs	585,679	708,698	21.00
Construction Costs	1,312,527	1,163,524	(11.35)
TOTAL	1,898,206	1,872,222	(1.37)

Operating margin for the quarter increased to 39.15% from 34.66% in 4Q15, as a result of the 5.90% increase in revenues along with the 1.37% reduction 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 62.95% in 4Q16 compared with 63.23% in 4Q15.

Comprehensive Financing Gain (Loss) for 4Q16 was a Ps.1.37 million loss, compared to a Ps.0.56 million loss in 4Q15. Interest expenses rose by Ps.5.22 million during the period, mainly due to the increase in interest rates. Interest income increased by Ps.10.95 million reflecting a higher cash balance.

Furthermore, in 4Q16, ASUR reported a foreign exchange loss of Ps.23.87 million, reflecting a 3.25% quarterly average depreciation of the Mexican peso against the U.S. dollar on ASUR’s lower foreign currency net liability position. This compared to a Ps.17.33 million loss in 4Q15 resulting from the quarterly average Mexican peso depreciation during that period.

Total	(557)	(1,370)	(813)	145.96

In addition, in 4Q16, ASUR recognized a Ps.150.00 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 6.41% depreciation of the peso against the U.S. dollar, between the close of 4Q16 and the close of 3Q16.

Income (Loss) from Equity Investment in Joint Venture.

During 4Q16, our equity in the income of Aerostar, our joint venture with Highstar Capital IV and its affiliated funds, was a net gain of Ps.7.09 million. In addition, ASUR recorded a Ps.150.00 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 6.41% depreciation of the peso against the U.S. dollar, between the close of 3Q16 and the close of 4Q16. In 4Q15, ASUR reported a net loss of Ps.13.43 million from our equity in the income of Aerostar and a Ps.26.85 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 4Q16, total passenger traffic at SJU airport declined 0.98% to 2,109,394 from 2,130,361 in 4Q15.

Income Taxes for 4Q16 increased by Ps.30.45 million year-over-year, principally due to the following factors:

· A Ps.41.06 million increase in the provision for income taxes, reflecting a higher taxable income base at the Veracruz and Cancún airports, as well as at Cancún Airport Services; and taxable income at Huatulco airport.

· A Ps.9.94 million decline in deferred income taxes largely reflecting the recognition of the effects of the 1.86% increase in inflation during 4Q16 on the fiscal tax balance.

ASUR 4Q16, Page 7 of 18

Net income for 4Q16 increased by 25.54% to Ps.917.51 million, up from Ps.730.83 million in 4Q15. Earnings per common share for the quarter were Ps.3.0584 and earnings per ADS (EPADS) were US$1.4832 (one ADS represents ten series B common shares). This compares with earnings per share of Ps.2.4361 and EPADS of US$1.1815 for the same period last year. The higher net income principally reflects the 11.91% increase in passenger traffic. During 4Q16, ASUR reported a Ps.7.09 million gain corresponding to its participation in Aerostar, the joint venture to operate SJU airport, compared to a net loss Ps.13.43 million in 4Q15.

2. Adjusted EBITDA Margin excludes the effect of IFRIC12 with respect to the construction or improvements to concessioned assets, and is calculated by dividing EBITDA by total revenues less construction services revenues.

Consolidated Results for Fiscal Year 2016

Total revenues for FY16 increased year-over-year by 8.44% to Ps.9,753.49 million, mainly due to the following increases:

· 15.56% in revenues from aeronautical services as a result of the 8.67% increase in passenger traffic during the period; and

· 24.58% in revenues from non-aeronautical services, principally due to the 25.42% increase in commercial revenues detailed below.

ASUR 4Q16, Page 8 of 18

These increases were partially offset by the 17.97% decline in construction services due to lower capital investments made during the period.

Commercial revenues for FY16 rose by 25.42% year-over-year, principally due to revenue increases in the following areas:

·26.92% in retail operations;

·20.61% in duty-free stores;

·31.20% in food and beverage operations;

·36.53% in car rentals;

· 41.26% in other income;

·0.89% in advertising;

·10.08% in parking lot fees;

·25.70% in banking and currency exchange services;

·10.93% in ground transportation services; and

· 31.86% in teleservices.

(1) Represents ASUR’s operation of convenience stores in airports.

Total operating costs and expenses for FY16 declined by 2.05% year-over-year, primarily due to the 17.97% 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:

ASUR 4Q16, Page 9 of 18

· 16.78% in cost of services, principally due to higher energy, security and maintenance expenses in connection with the Terminal 3 expansion. Higher cost of sales from the convenience stores directly operated by ASUR, together with higher software license, professional fees, and office leases also contributed to this increase;

· 18.33% in concession fees paid to the Mexican government, mainly due to an increase in regulated revenues (a factor in the calculation of the fee);

·20.46% in technical assistance costs, reflecting the corresponding increase in EBITDA during the period;

·12.93% in depreciation and amortization, resulting mainly from higher capitalized investments; and

·3.99% in administrative expenses, principally reflecting higher professional fees and security expenses.

Excluding construction costs, operating costs and expenses rose 15.50% to Ps.2,703.94 million.

TOTAL	4,921,700	4,820,892	(2.05)

Operating Margin in FY16 increased to 50.57% from 45.28% in FY15. This was mainly the result of the 8.44% increase in revenues combined with the 2.05% decline in expenses in the year.

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, increased to 64.59% in FY16 from 63.50% in FY15.

ASUR 4Q16, Page 10 of 18

Comprehensive Financing Gain (Loss) for FY16 was a Ps.45.47 million loss, compared to a Ps.109.96 million loss in FY15, principally due to a Ps.103.85 million foreign exchange loss in FY16 reflecting the 19.54% average depreciation of the Mexican peso against the U.S. dollar on ASUR’s foreign currency net liability position, as compared to a Ps.168.66 million foreign exchange loss in FY15 resulting from the impact of the 17.01% average depreciation of the Mexican peso against the U.S. dollar on ASUR’s foreign currency net liability position.

Interest income increased by Ps.28.85 million in the year, reflecting a higher cash position, while interest expense increased by Ps.29.17 million, reflecting higher interest rates.

Tariff Regulation

The Mexican Ministry of Communications and Transportation regulates the majority of ASUR’s activities by setting maximum rates, which represent the maximum possible revenues allowed per traffic unit at each airport.

ASUR’s regulated revenues for FY16 were Ps.4,762.54 million, resulting in an annual average tariff per workload unit of Ps.157.08. ASUR’s regulated revenues accounted for approximately 62.37% of total income (excluding construction income) for the period.

Compliance with maximum rate regulations is reviewed by the Mexican Ministry of Communications and Transportation at the close of each year.
