Less than a month after officially going live, SNR Denton has landed a key role advising $6 billion Brazilian hedge fund Gavea Investimentos on the sale of a controlling stake to Highbridge Capital Management, the global alternative asset manager owned by JPMorgan Chase.

SNR Denton was created through a merger announced in May between Sonnenschein Nath & Rosenthal and British firm Denton Wilde Sapte. The combined 1,400-lawyer firm won the lead role advising Gávea and its founder, Arminio Fraga, the former head of Brazil’s central bank, according to U.K. legal publication Legal Week.
