Time of publication:  16:03

Pemex, the oldest industrial partner of Repsol company, and Sacyr Vallehermoso (SyV), the industrial partner with the highest number of shares in Repsol (20%), have entered into an agreement today in order to jointly vote in the most important decisions to be taken at the Spanish oil company.  In addition, Pemex will acquire in the market 5% of Repsol shares, thus increasing its stockholding to 9.8%.

Both shareholders share the same forward-looking approach, which, in sum, is evident in the following goals:  to maintain Repsol as a Spanish and independent oil company; to further international best practices in corporate governance and social responsibility; and to reach efficiency in Repsol’s management and in the management of its subsidiary companies, driving coordination and attainment of synergies, as well as to establish representation in the administration and management bodies of Repsol, in accordance to voting rights.

Pemex is the fourth largest crude oil producer in the world and has been assessed as the eleventh largest integrated oil company worldwide.1

In addition, in Mexico, Pemex is the only crude oil, natural gas and petroleum products producer, as well as the most important income source of the Mexican Government and the most important company of the country.

Sacyr Vallehermoso, a company listed in the Ibex-35, is one of the largest Spanish infrastructure groups, and is diversified in the areas of construction, franchises, services, equity, real estate and energy.  It has a presence in five continents, with a portfolio of 51,000 million euros,  61% of which stems from international activity, with works such as the construction of the third set of locks of the Panama Canal or the Messina bridge, among others.
