In 1998, the construction company Ros Casares acquired the team and in 2001 the club won its first league with this denomination.

In subsequent years the team became a regular in the EuroLeague and fought tightly with UB Barcelona, which disappeared in 2007.

That season marked the beginning of Ros Casares' golden era, with four national doubles in a row and two EuroLeague finals lost to Spartak Moscow Region.

Following an unsuccessful 2010–11 season where Ros Casares lost the national titles to Perfumerías Avenida and Rivas Ecópolis the team was greatly strengthened and it won the 2012 EuroLeague by beating UMMC Ekaterinburg, Spartak Moscow Region, Wisła Kraków and finally Rivas Ecópolis in the new Final Eight,[2] in addition to its eighth national championship.
