Mexico City, Mexico, December 18, 2025—Mexican airport operator Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA (NASDAQ: OMAB; BMV: OMA), announced that it has received approval of the Master Development Program (MDP) for each of its airports for the 2026–2030 period, granted by the Ministry of Infrastructure, Communications and Transportation (SICT) through the Federal Civil Aviation Agency (AFAC).

The 2026–2030 Master Development Programs contemplate committed investments of Ps.16,005 million, expressed in December 2024 pesos, aimed at comprehensively strengthening the infrastructure and operations of OMA’s airport network. The programs prioritize the expansion and modernization of terminal facilities, the development and rehabilitation of aeronautical infrastructure, as well as the incorporation of equipment and technology, with a focus on optimizing operational processes, increasing installed capacity, and enhancing the passenger experience. These investments are designed to efficiently accommodate the expected growth in passenger and cargo demand over the five-year period.

In addition, the MDPs incorporate investments in sustainability, energy efficiency, and decarbonization projects, aimed at reducing the environmental impact of airport operations and strengthening the efficient use of resources. These investments include improvements in infrastructure, technology, and operational processes, and are aligned with OMA’s sustainability strategy, contributing to a more efficient and environmentally responsible airport operation over the long term.

The committed investments corresponding to the approved Master Development Programs, expressed in thousands of pesos as of December 31, 2024, are as follows:

The approved Maximum Tariffs per workload unit¹ for each airport, expressed in pesos as of December 31, 2024 and adjusted by an annual real efficiency factor of 0.8%, are as follows:
