Within: Banking and finance

Shearman & Sterling LLP’s long presence in Latin America has afforded it prime connections to lenders and borrowers, spanning key product areas such as acquisition finance, bilateral and syndicated loans, project finance, and restructurings and refinancings. The firm recently reinforced its finance capabilities in Latin America with the hire of counsel Roberta Berliner Cherman in São Paulo; a former associate at the firm, Cherman subsequently spent nine years as an in-house counsel at Brazil’s Itaú Unibanco. Recent work has seen the team advise the joint lead arrangers on a $1.5bn refinancing for Petróleos Mexicanos (Pemex) and represent the lead arrangers on a $400m financing for Mexican multinational food manufacturing company Gruma, involving a $250m senior unsecured revolving credit facility and a $150m senior unsecured term loan facility. The practice has also impressed in restructurings and financings in Brazil, and has a market leading presence in energy, mining and infrastructure financings. Key clients include Banco BTG Pactual, Banco Santander Brasil, Banco Santander Chile and Caixa Econômica Federal. Denise Grant has a market leading presence in acquisition finance, most notably in Mexico, Chile and Peru, although she is equally adept in corporate loans and project finance; Grant has further experience in the Caribbean and is praised for her ability to prioritise issues and ‘maintain excellent relationships with her clients’. Global head of the firm’s project development and finance group, Gregory Tan is an industrious figure with a high profile in the region. Cynthia Urda Kassis is a leading name in the mining sector, but also has broader expertise in energy and infrastructure; she is regarded as ‘on point and nuanced’ in her approach, with one peer suggesting that she is the benchmark for young lawyers to aspire to and another highlighting that she is ‘delightful to work with’, ‘sticks to her guns when she needs to’ but is ‘willing to get things done’. Alexandro Padrés, a Mexican national, has a fine record in power sector financings in Mexico. Paul Epstein, a project development and finance specialist with Latin America experience, was promoted to partner in January 2018. All named partners are based in New York unless stated.
