Three men have been found guilty of abducting and torturing Quinn Industrial Holdings director Kevin Lunney, in September 2019.
One of them can’t be named for legal reasons.
The other two are: Alan O’Brien and Darren Redmond, both from East Wall in Dublin city.
A fourth man - 68-year-old Luke O’Reilly of Mullahoran Lower, Kilcogy, Co Cavan - was found not guilty.
During the trial, Mr Lunney gave evidence of being taken to a horse trailer where he was beaten and slashed with a knife while one of his attackers demanded he resign.
A sentence hearing for the three men who were convicted today will take place later this month.
