Stuart Bayes found guilty of insider dealing

Mr Stuart Bayes was recently (28 March 2024) found guilty of 2 offences of insider dealing, following an 8-week trial at Southwark Crown Court in a prosecution brought by the Financial Conduct Authority (FCA).

Mr Bayes was employed as a site manager at UK plastic manufacturer, RPC Group Plc (RPC). Through his employment he obtained confidential information, known as ‘inside information’, that RPC were about to announce the acquisition of British Polythene Industries (BPI).

Between 2 May 2016 and 8 June 2016, ahead of the market announcement that RPC had agreed to buy BPI on 9 June 2016, Mr Bayes undertook increasingly aggressive trading in BPI shares.  He also encouraged a further individual, Mr Jonathan Swann, to trade in BPI shortly before market close on the 8 June.

On 9 June Mr Bayes closed his position realising a profit of just over £132,000.

He will be sentenced on 26 April 2024.

Mr Jonathan Swann was found not guilty of insider dealing.

At a previous trial in 2022, a jury failed to reach a verdict in the case, with the FCA pursuing a retrial which began in February 2024.

Steve Smart, Joint Executive Director of Enforcement and Market Oversight at the FCA, recently said:

“In this case, a senior staff member at a listed company abused his position for personal profit.

“Such conduct undermines financial markets and public trust in them.

“Our determination to secure this conviction sends a clear message that we will take action to protect UK markets from bad actors.”
