OMA Completes Placement of Ps. 1,300 Million in 5-Year Notes

MONTERREY, Mexico, July 15, 2011 (GLOBE NEWSWIRE) — 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 Ps. 1,300 million in 5-year peso-denominated Notes (Certificados Bursátiles) in the Mexican market. The interest rate on the Notes is the 28-day TIIE (the Interbank Equilibrium Interest Rate) plus 0.70%. The notes received a rating of mxAA+ from Standard & Poor’s and AA+ (mex) from Fitch Ratings.

OMA expects to use the proceeds of the offering to prepay Ps. 1,006 million in existing debt. The balance of the proceeds is expected to be used to fund committed investments under OMA’s Master Development Program for its 13 airports, as well to make strategic investments.

This is the first issuance of Notes by any of the Mexican airport groups, and the transaction will lower OMA’s cost of debt and improve its debt maturity profile.

This press release is for information purposes only and does not constitute an offer to sell or the solicitation of an offer to purchase the Notes.
