ASUR Announces Total Passenger Traffic for March 2021

On a YoY basis, passenger traffic increased 0.2% in Mexico, 42.9% in Puerto Rico and

22.0% in Colombia

Mexico City, April 7, 2021 - Grupo Aeroportuario del Sureste, S.A.B. de C.V. (NYSE: ASR; BMV: ASUR) ASUR, a leading international airport group with operations in Mexico, the U.S. and Colombia, today announced that total passenger traffic for March 2021 increased 11.3% when compared to March 2020. Passenger traffic increased 0.2% in Mexico, 42.9% in Puerto Rico and 22.0% in Colombia, reflecting a recovery, mainly in Puerto Rico and Colombia, when compared to the year- ago period which was significantly impacted by severe downturns in business and leisure travel stemming from the COVID-19pandemic. Nonetheless, the pandemic continues to impact overall travel, with traffic in Mexico relatively unchanged YoY. Traffic in March 2021 also benefitted from 4 days of the Holy Week Holiday.

This announcement reflects comparisons between March 1 through March 31, 2021 and from March 1 through March 31, 2020. It must be taken into account that Holy Week in 2020 took place between April 5 and 12, while in 2021 it took place from March 28 to April 4. Transit and general aviation passengers are excluded for Mexico and Colombia.
