The Federal Police and the Brazilian Securities and Exchange Commission (CVM) conducted an operation to investigate whether JBS made improper use of inside information to profit in the financial market in the days leading up to the plea bargain of Joesley and Wesley Batista. Operation “Tendão de Aquiles” examined whether the executives had committed the crime of insider trading. However, in 2023, the CVM acquitted the businessmen of all charges related to the case.
