ASUR Announces that Nacional Financiera has Started the Bidding Process for
the Auction of its Stake in Inversiones y Tecnicas Aeroportuarias, the
Company’s Strategic Partner

Mexico City, October 28, 2004, Grupo Aeroportuario del Sureste, S.A. de C.V. (NYSE: ASR; BMV: ASUR) (ASUR) the first privatized airport group in Mexico and operator of Cancun Airport and eight others in the southeast of Mexico, today announced that it has been notified by its strategic partner, Inversiones y Tecnicas Aeroportuarias S.A. de C.V. (ITA), that Nacional Financiera, S.N.C. (NAFIN) began yesterday the bidding process for the auction of its 25.5% ownership in ITA.

ITA became ASUR’s strategic partner when it acquired 15% of ASUR’s capital in 1998 as part of the privatization of the airport system in Mexico. Its stockholders are:

• Mr. Fernando Chico Pardo 38.0%
• Copenhagen Airports A/S 36.5%
• Nacional Financiera, S.N.C. 25.5%

NAFIN’s ownership stake in ITA, corresponds to that of the “Mexican Partner”, and as such the offer is being made to persons or entities that are Mexican under applicable law. This stake was acquired by NAFIN on January 8, 2004, from Triturados Basálticos y Derivados, S.A. de C.V. (Tribasa), ITA’s original Mexican partner, as part of Tribasa’s settlement with its creditors. As a result, NAFIN became ITA’s temporary Mexican partner, until its ownership stake is sold to another shareholder, who meets the requirements to be part of ITA as its Mexican partner.

According to the original agreements signed by ASUR and the Mexican Federal Government, Copenhagen Airports, acting as ITA’s operating partner, and Tribasa, acting as the Mexican partner, were required to maintain their ownership stake in ITA for 15 years (except for transfers permitted under certain conditions provided in such agreements). These conditions were satisfied in connection with Tribasa’s transfer to NAFIN and are required to be satisfied by the buyer of the 25.5% ownership stake in ITA being auctioned by NAFIN.
