The strength of our practice is having a dedicated team of mostly bilingual or trilingual lawyers that fully understand the legal and political challenges within the local landscapes and have the cultural and business skills to work effectively in the region.

In addition, we counsel Latin American companies and their creditors on restructuring transactions, tender offers, exchange offers, consent solicitations and negotiated restructurings.


The lawyers in our Latin American Corporate/M&A practice represent a broad spectrum of public and private companies, private equity and leveraged buyout firms, special committees, closely held companies, management groups, and individuals across the region. We also regularly advise regional, national and global investment banks in their roles as financiers or financial advisors in M&A transactions. We have particular knowledge of the energy and natural resources sectors, where our team has extensive experience in transactions related to oil and gas, LNG, power, and mining across the region. Whatever the transaction, we are known for delivering both top-level client service and creative solutions to complex problems.


Within Latin America, we offer experienced bilingual teams with in-depth experience in each of the major energy sectors, from oil and gas to renewable energy and power. We devise creative solutions to complex problems.
