Mexican Airport Operator OMA Announces Initial Public Offering on the NASDAQ Global Select Market and the Mexican Stock Exchange


Monterrey, Mexico, November 29, 2006—Mexican airport operator Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., commonly known by its trade name OMA, announced that the initial offering price for its American Depositary Shares (ADSs) has been fixed at US$18.00 per ADS. The offering price of the Series B shares is Ps. 24.85 per share. Each ADS represents eight Series B shares. Trading will begin today, November 29, 2006. The ADSs are listed on the NASDAQ Global Select Market under the ticker symbol "OMAB," and the Series B shares are listed on the Mexican Stock Exchange (Bolsa Mexicana de Valores) under the ticker symbol "OMA."

The initial public offering consists of 167 million OMA Series B shares (in the form of shares or ADSs), constituting an offer size of approximately US$376 million, excluding the over-allotment option. The underwriters have a thirty-day option to purchase an additional 25 million Series B shares (15 percent of the amount being offered) to cover over-allotments. The Series B shares being sold, including those subject to the over-allotment option, represent approximately 48 percent of OMA's total equity.

All the Series B shares are currently outstanding and are being sold by the Mexican government, acting through its development bank Nacional Financiera, S.N.C. (NAFIN). The sale is being coordinated by Mexico's Ministry of Communications and Transportation (SCT). Once all the Series B shares and ADSs have been placed, including full exercise of the over-allotment option, the Mexican government will have completed the privatization of OMA that began in 2000.

OMA will not receive any proceeds from the sale of shares or ADSs.
