In 2007, SENER President, Jorge Sendagorta, signed with III General Manager, Eduardo Bosque, the purchase agreement of the 40% of III, with the compromise of acquiring 100% of the Mexican engineering company in 2010. Since then, SENER and III have been consolidating their relationship until they have culminated this operation with the constitution of the new company III Grupo SENER. The purchase of the 100% of III by the Spanish engineering company SENER closes a process that began in March 2005, when both companies signed a strategic alliance. By virtue of this alliance, SENER entered the Mexican market with one of the country's main engineering companies, while also promoting III's capacity to contract turnkey projects.
