Mayer Brown has supported us in several transactions during the year. They are an office in whom we can trust that they will provide us with a very professional service. In one of the transactions that we did, they found a very creative way to close the promissory note, so that all the banks felt comfortable with the proposed scheme while the powers of attorney were legalised in Mexico.

In the transactions that I worked with Mayer Brown during the year I had to work with David Duffee, Partner in NY and Raúl Fernández-Briseño, Partner in Mexico. They both provided excellent service and were always available to resolve any issues that arose. With Raul in particular, he is a very trusting attorney and I appreciate his feedback.

The Latin America team has also advised on a number of LNG-to-power and gas-to-power M&A transactions, and continues to be involved in renewable energy deals in Chile. Houston partners Pablo Ferrante and Jose Valera have a huge amount of experience in energy M&A; in Brazil, Carlos Motta is a key name in Sao Paulo as is Alexandre Chequer in Rio de Janeiro; and in Mexico City, Raúl Fernández-Briseño is the key transactional contact. Vera De Gyarfas moved in-house in July 2021.

They have a very strong Latam practice. I was able to witness how they can successfully bridge cultural and legal differences. They can easily interact with US law firms, as well as local Latam law firms and Latam-based clients.

To usual legal proficiency of top US firms, Mayer Brown adds great local knowledge for Latam deals as well as being a very effective interphase among all parties and advisors in the transactions.
