A&O Shearman was formed in May 2024 following the merger of two historic international law firms, Allen & Overy and Shearman & Sterling. The firm is recognised as one of the leading practices in Spain, advising on a broad range of domestic and cross-border transactions. The Madrid team is led by highly regarded partners Ignacio Ruiz-Cámara and Antonio Vázquez-Guillén. The firm enjoys a strong reputation in Spain, achieving top-tier rankings across its main practice areas.

Highlights 

The firm advised a syndicate of banks on the €1.2 billion debt refinancing of the PTI Group.

The firm also recently advised Deutsche Bank on a €932 million real estate refinancing of Blackstone entities and the liquidation of the FTA2015 Fund.

In M&A, the firm advised Repsol on the $19 million sale of a 25% stake in its upstream business by EIG. The team also advised Abertis on its €115 million acquisition of Autovia del Camino from UBS.
