ASUR PROPOSES TO ITS SHAREHOLDERS THE INTERNALIZATION
OF TECHNICAL ASSISTANCE SERVICES, AN EXTRAORDINARY
DIVIDEND, AND AN AMENDMENT TO THE COMPANY’S BYLAWS
Mexico City, Mexico, June 23, 2026 - 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 United States, and Colombia, announces that its Board of Directors has resolved to propose to our shareholders the integration of the technical assistance and technology transfer services business, which have been outsourced to our strategic partner, Inversiones y Técnicas Aeroportuarias, S.A.P.I. de C.V. “ITA,” since the start of our operations and which we consider essential.
Bringing these specialized technical assistance and technology transfer services in-house represents a significant step in our strategy to strengthen our profitability and streamline our operations. Under the new structure, ASUR would assume the technical assistance and technology transfer functions currently provided by ITA.
Our Board of Directors’ decision to submit this proposal to our shareholders for approval is based on an initiative by our management and was overseen and led by our Audit and Corporate Governance Committee, which, in turn, was supported by J.P. Morgan Securities LLC, “J.P. Morgan,” and Bufete Robles Miaja, S.C., as independent external advisors.
The internalization will be carried out through the merger of one or more entities into ASUR. The material terms of the internalization will be described in an information document that will soon be available to assist shareholders in their free and informed decision-making process on our website at the following address: www.asur.com.mx and on the website of the Mexican Stock Exchange, S.A.B. de C.V., at the following address: www.bmv.com.mx, once an Extraordinary General Shareholders’ Meeting is called.
As a result of this business combination, if approved by our shareholders, we would expect to issue and put into circulation approximately 7,251,000 new shares representing our capital stock, under the terms described in the aforementioned information document.
It was agreed to pay two extraordinary net cash dividends charged against the share repurchase reserve in the amount of Ps.10.00 (Ten pesos 00/100, National Currency), each, payable in November and December 2026, to be paid in a single installment on each of the Series “B” and “BB” common shares representing paid-in capital that are issued, subscribed, paid up, and fully paid on that date, and (ii) the payment of any taxes payable by the Company in accordance with applicable tax provisions as a result of the payment of such dividend.

It was approved that payments of the extraordinary dividends be made through the Equities Division of S.D. Indeval Institución para el Depósito de Valores, S.A. de C.V., at its offices located at Paseo de la Reforma No. 255, 3rd floor, Colonia Cuauhtémoc, 06500, in Mexico City, Monday through Friday from 9:30 a.m. to 1:00 p.m., beginning on November 24, 2026, and December 15, upon presentation of coupons “23” (twenty-three) and “24” (twenty-four) of the currently outstanding securities, under the terms to be notified to shareholders in due course.
It was agreed to publish the notice of payment of the aforementioned dividends in a widely circulated newspaper once it is approved by the next shareholders assembly.
The Board of Directors also approved proposing to the Shareholders’ Meeting an amendment to the Company’s bylaws to bring them into compliance with the current regulatory framework and, should the internalization be approved, a bylaw amendment resulting therefrom.
THIS MATERIAL EVENT IS NOT AN OFFER TO SELL SECURITIES IN MEXICO, THE UNITED STATES OF AMERICA, OR ANY OTHER JURISDICTION.
