About

Provided by Sullivan & Cromwell LLP

S&C consistently leads the market in advising on Latin America M&A matters. We rank as the number one legal advisers on M&A by deal value over the last 10 and 15 years according to Refinitiv, having worked on precedent-setting matters in almost every country in Central and South America.

Our Latin America practice remains at the forefront in providing sophisticated counsel for companies and institutions within the region, as well as for multilatinas and multinationals with involvement in Latin America, on complex cross-border matters. We have advised on many largest-of-their-kind transactions and on nearly every major financial services asset sale in the region since the financial crisis.

Our client base covers a wide range of sectors including airlines, financial institutions, private equity, healthcare, telecommunications, consumer and construction products, real estate, and energy and natural resources. Recently, we have been advising Sumitomo Metal Mining (SMM) and Sumitomo Corporation (SC) on their pending sale to South32 Limited of the entirety of their collective 45% interest in Sierra Gorda ($1.19 billion for SMM’s 31.5% stake and $510 million for SC’s 13.5% stake), AT&T Inc. in its pending sale of Vrio Corp. to Grupo Werthein (Argentina); Canadian Pacific Railway in its merger agreement with Kansas City Southern worth $31 billion, which would create the first single-line rail network linking U.S.-Mexico-Canada; and more.
