Corporate and M&A Tier 3

A respected name for corporate law’, Allende & Brea strikes the right note with its ‘solid technical knowledge’, ‘committed partners’ and ‘fast turnaround times’. The group, which sources highlight as increasingly active in the market, enjoys a strong reputation for agribusiness-related transactions — it has also recently acted for clients in the TMT, energy and pharmaceutical industries. Department co-head Valeriano Guevara Lynch is a ‘very skilled specialist’; he recently advised Sapphire Systems on its acquisition of assets from Argentis Consulting. Santiago Sturla, who co-heads the practice, advised Ferrero International on the local aspects of its $2.8bn acquisition of Nestlé’s US confectionery business.

The ‘effective and compact team’ at Allende & Brea strikes the right note with its ‘calm and strategic approach’.
