Spanish construction and energy company Acciona said Tuesday it reached an agreement to sell its interest in Mexico's Concesionaria Politecnica de San Luis to Macquarie Mexican Infrastructure Fund, or MMIF, for 38 million euros ($46.7 million).

The deal is part of a plan to sell mature assets and seek new investment opportunities in strategic areas, Acciona said in a statement.

The Mexican business had net debt of 14 million euros ($17.2 million) as of June 30 and is being accounted for as a discontinued operation pending sale, Acciona said.

Concesionaria Universidad Politecnica de San Luis de Potosi is handling the construction, financing, operation and maintenance of a public university campus in the central state of San Luis Potosi.

Under the terms of the agreement, Acciona said it would continue to handle operations and maintenance at the university via Operadora de Servicios de Infraestructuras Sociales.

Acciona plans to continue its contract operations business in Mexico, where it has a 25-year franchise for the Hospital Regional de Alta Especialidad del Bajio, which began operations in 2007.

Mexico will continue to be a strategic market, Acciona, which has infrastructure, renewable energy and water businesses in that country, said. EFE
