OMA Announces Achievement of its Sustainability

Performance Target

Mexico City, Mexico, June 25, 2026— Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA (NASDAQ: OMAB; BMV: OMA), announces that the Company has achieved the Sustainability Performance Target (“SPT”) associated with its sustainability-linked bonds (certificados bursátiles vinculados a la sostenibilidad) issued under the ticker symbols OMA 22L, OMA 22-2L, OMA 23L and OMA 23-2L.

The STP consisted of reducing Scope 1 and Scope 2 greenhouse gas emissions, measured as kilograms of CO₂ equivalent per passenger (kgCO2e/PAX), by 58% as of December 31, 2025 , compared to the 2018 baseline year. As of 2025, the Company achieved an 88% reduction, exceeding the established target.

This achievement was made possible through the implementation of a strategy based on two key pillars: energy efficiency and the decarbonization of airport operations.

Regarding energy efficiency, OMA has invested in high-efficiency systems, equipment and infrastructure optimization, as well as projects aimed at reducing energy consumption across its airports.

Regarding decarbonization, the Company has implemented initiatives to increase the use of renewable energy and reduce emissions associated with its operations, including the installation of solar panels, the procurement of renewable electricity through Power Purchase Agreements (PPAs), the deployment of battery energy storage systems, and the gradual transition to electric and hybrid vehicles within its airport operations.

Achievement of the SPT has been verified by the external verifier Áddere Solutions, S.C. Annex A to this release includes the "Verification Report of the kgCO₂e/PAX Metric" issued by Áddere Solutions, S.C. for the fiscal year ended December 31, 2025.

OMA remains committed to advancing energy efficiency and decarbonization initiatives across its airports, further strengthening the resilience of its operations.
