The conviction of Guilherme Esteves de Jesus is part of one of the largest corporate corruption probes in history, Brazil's wide-ranging "Car Wash" investigation that was launched in 2014.
"...GDJ (Guilherme Esteves de Jesus) has been convicted by the Federal Courts of Curitiba...," Sembcorp Marine said in a statement, adding he was sentenced to 19 years and four months in prison and was also fined.
Sembcorp Marine reiterated that besides Martin Cheah, the former president of its Estaleiro Jurong Aracruz (EJA) shipyard, it was not aware of any other current or former employee who is a subject of the "Car Wash" investigations. Esteves de Jesus is a former consultant engaged by EJA in Brazil.
Reuters was not immediately able to contact Esteves de Jesus or Cheah for comment. A lawyer for Esteves de Jesus did not respond to a phone call outside business hours.
Shares of Sembcorp Marine were down 1.7% on Friday, extending losses for a second day.
