Jean-Charles Naouri, the former chief executive of French retailer Casino, has been convicted of corruption and disseminating false information in a case tied to efforts to prop up the company’s share price in 2018. A French court sentenced Naouri to four years in prison, three suspended and one under electronic surveillance, and fined him €1m ($1.19m). He is appealing the ruling. The court found that Mr Naouri and three other ex-Casino executives paid a journalist €823,000 to spread false rumors of a Carrefour takeover bid to support Casino’s stock. All were found guilty of corruption and misinformation, while two were also convicted of insider trading. Casino itself was fined €40m, half suspended.
