Latin America: International firms

Corporate and M&A

Within: Corporate and M&A

Shearman & Sterling LLP has demonstrated great determination to build out its M&A practice in Latin America. Having promoted São Paulo’s Jonathan Kellner, a fluent Spanish and Portuguese speaker who is a ‘star in his field’, to partner in 2016, it then promoted São Paulo-based Andrea Campos to counsel in 2017. This comes at a time when the firm is experiencing notable growth in Brazil inbound transactions along with deals in other key economies such as Argentina, Chile, Colombia and elsewhere. The core Latin America team has done well to target existing firm clients, including corporates and sovereign wealth funds. Kellner worked alongside New York partner Robert Freedman to advise GE Capital Global Holdings on its acquisition of a 25% stake in YPF Energía Eléctrica from Argentine oil-major, YPF. A New York team led by global M&A head (and global co-managing partner of the firm) George Casey, advised Liberty Global on its $9.3bn spin-off of Liberty Latin America. In another headline deal, it also advised Citigroup’s Mexican subsidiary Citibanamex on the sale of its asset management arm to global investment manager BlackRock. Other key partners include Latin America regional head Antonia Stolper, Manuel Orillac and Robert Ellison in São Paulo.
