OMA announces debt placement of Ps.3.0 billion

MexicoCity, Mexico, July 16, 2026— Mexican airport operator Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA (NASDAQ: OMAB; BMV: OMA), announces the placement of long-term notes in the Mexican market for an aggregate amount of Ps.3.0 billion (the “Issuances”).

The Issuances were widely accepted through the participation of pension funds “Afores”, governmental entities, insurance companies, and investment funds. Combined demand for both tranches was 3.2x.

The Issuances are the following:

The Issuances received the highest rating in Mexico of AAA(mex) by Fitch and AAA.mx by Moody’s Local, both on a national scale, with stable outlook.

Book building was held today, and the settlement will be on July 20, 2026. Net proceeds from the Issuances will be used to prepay Ps.1.7 billion short-term bank loans, Ps.640 million for the full repayment of the OMA 23L long-term bond certificates, maturing on July 24, 2026, and the remaining proceeds will be used to fund committed investments under the Master Development Program, as well as for general corporate purposes, including working capital.

This press release is for information purposes only and does not constitute an offer to sell, nor the solicitation of an offer to purchase the Notes.
