ADP ADP Promesses

Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA (NASDAQ:OMAB) (BMV:OMA), and Empresas ICA, S.A.B. de C.V. (BMV:ICA) announce that Groupe ADP (EPA:ADP) has informed them of its decision to exercise its option to exchange its 25.5% shareholding in Servicios de Tecnología Aeroportuaria S.A. de C.V. (SETA), the strategic partner of OMA, for OMA B shares held by SETA, which represent 4.3% of OMA’s total equity (3.2% net of taxes), and of its intention to sell this equity interest in OMA through an international private placement outside Mexico.

ICA

SETA will remain OMA’s strategic partner.  Upon completion of the transactions, ICA’s wholly-owned subsidiary Controladora de Operaciones de Infraestructura, S.A. de C.V. (CONOISA) will be the sole shareholder of SETA, which in turn will hold 12.4% of OMA, all in the form of BB shares.  SETA will continue to exercise its rights as OMA’s strategic partner, as at present.  In addition, CONOISA owns 1.9% of OMA’s B shares directly.

OMA does not expect that the change in the strategic partner’s composition will affect the operations of the airport group, and OMA will continue to provide airport services of the highest quality.

OMA and ICA have been pleased with the strategic partnership with ADP since 2000; the parties expect that ADP will continue to provide certain technical support to SETA under appropriate service arrangements, including participation on behalf of SETA on OMA’s Board of Directors until the next Annual Shareholders’ Meeting.
