MEXICO CITY--(BUSINESS WIRE)--April 26, 2001

First Quarter Highlights - year-over-year comparisons:

-- EBITDA up 8.05 % to Ps.206.2 million

-- A 2.85% decline in revenues from aeronautical services for the quarter, in
connection with the inclusion of a provision for maximum rates compliance; and

-- A 7.85% improvement in revenues from non-aeronautical services for the
quarter principally from revenues from permanent ground transportation and
rental income

Grupo Aeroportuario del Sureste, S.A. de C.V. (NYSE: ASR; BMV: ASUR) (ASUR), the Mexican airport operator of Cancun International Airport and eight other airports in the southeast region of Mexico, announced today results for the three-month period ended March 31, 2001.

All figures in this report are unaudited and are prepared in accordance with Generally Accepted Accounting Principles in Mexico. All figures are presented in constant Mexican pesos as of March 31, 2001. All figures in the tables are in thousand of pesos, unless otherwise indicated. All passenger figures exclude transit passengers and general aviation. Figures for 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=Ps.9.4933.

Passenger Traffic in the First Quarter of 2001

Total passenger traffic for the three-month period ended March 31, 2001, rose year-over-year by 4.99%, mainly as a result of an 8.51% improvement in total international passenger traffic, which offset the 1.28% decline in total domestic passenger traffic experienced for the quarter.

At the airport of Cozumel, domestic passenger traffic for the quarter declined year-over-year by 15.70%, mainly due to the increase in the number of direct international flights to this airport without connection through Cancun. This was more than offset by a year-over-year 7.62% improvement in international passenger traffic for the period, which resulted in a year-over-year rise in total passenger traffic for the first quarter of 2.07% at Cozumel.

Tapachula Airport experienced a year-over-year decline in domestic passenger traffic for the quarter of 29.76% , principally due to the temporary suspension in February of this year one of flights to this airport from Mexico City by the airline AVIACSA.

At the airport of Minatitlan, domestic passenger traffic for the quarter declined year-over-year by 13.19%, as a result of the slowdown of the economic activity in the area during the period.

Overall, the decline in domestic passenger traffic for the quarter experienced by ASUR was more than offset by the rise in international passenger traffic registered in the period at all airports, with the exception of Villahermosa.

Consolidated Results for First Quarter of 2001

Revenues

Consolidated revenues for the quarter declined year-over-year by 1.49% to Ps.317.0 million, mainly as a result of:

-- A 2.85% decline in revenues from aeronautical services for the quarter, in
connection with the inclusion of a provision for maximum rates compliance; and

-- A 7.85% improvement in revenues from non-aeronautical services for the
quarter principally from revenues from permanent ground transportation and
rental income

Commercial Revenues

ASUR classifies the following activities as commercial revenues: duty free, car rental, retail, banking and money exchange, advertising, teleservices, non-permanent ground transportation and retail, food and parking lots. For regulatory purposes, the Mexican Airport Law defines three kinds of Services: airport, commercial and complementary. Under the law, parking lots and non-permanent ground transportation were not defined in any of these categories.

Commercial revenues for the quarter declined year-over-year by 3.47%, mainly as a result of:

-- An 11.03% year-over-year decline in retail revenues for the

quarter, mainly due to the closing of a number of stores in

connection with the remodeling taking place at ASUR's

airports.

-- A 78.40% year-over-year decline in revenues generated by

non-permanent ground transportation for the quarter in

connection with the dispute with the operators of pre-paid

transportation. Negotiations regarding this matter are

currently taking place.

This was partially compensated by:

-- An 80.34% year-over-year increase in duty-free revenues for

the quarter

-- A 186.11% year-over-year rise in revenues from parking lots

for the quarter in connection with the commencement of parking

lot operations in the second quarter of last year at the

airports of Cancun, Huatulco, Minatitlan and Tapachula. On

March 22, 2001, ASUR started parking lot operations also at

the airport of Veracruz, which contributed revenues of

Ps.74,080 through March 31. Prior to the second quarter of

2000, ASUR operated parking lots only at the airport of

Merida.

In December of last year, ASUR launched the first-ever international tender for retail concessions to cover the Company's three largest airports, Cancun, Merida and Cozumel. Retail is one of the most important generators of commercial revenues. The Company expects to make a formal announcement of the winner of the retail tender in the coming weeks.

The Company also launched a tender offer for convenience store concessions at all nine ASUR airports. The convenience retail business line includes offerings such as newspapers, magazines, candy, cigarettes, non-prescription pharmaceutical items, and other similar merchandise. ASUR expects to make a formal announcement of the winner of this tender also in the coming weeks.

During the first quarter, the Company finalized agreements with two of the eight car rental operators at the Cancun airport.

Operating Expenses

Cost of services for the quarter declined year-over-year by 14.10%, mainly as a result of a decline in salaries, consulting fees and maintenance costs.

Administrative expenses for the quarter declined year-over-year by 28.52%, reflecting a decline in costs for administrative personnel, partially offset by an increase in fees for third-party consultants for executive searches.

Cost of technical assistance for the quarter declined year-over-year by 12.12% in connection with the change in the way the technical assistance fee is calculated for the current year. ASUR's cost of technical assistance for 2001 will be equal to the greater of US$3 million or five percent of consolidated EBITDA for the year. In 2000, ASUR's cost of technical assistance was US$5 million. The fixed amounts for 2000 and 2001 are adjusted annually for inflation, measured by the US consumer price index, as from the first anniversary of the technical assistance agreement, 1999.

Concession fees for the quarter declined year-over-year as a result of the decline in revenues for the period.

Operating margin for the quarter improved year-over-year to 41.90%, from 36.55%. This was the result of the year-over-year declines of 1.49% in consolidated revenues and of 9.79% in certain costs, as explained above.

Net income for the first quarter of 2001 rose year-over-year by 36.44%. Earnings per ordinary series B share (EPS) for the quarter were Ps.0.3119, or earnings per ADS (EPADS) of US$0.3285, compared with EPS of Ps.0.2286, or EPADS of US$0.2408, for the same quarter last year.
