The jury of nine men and three women deliberated for just under four hours before bringing in a unanimous verdict.
Victim impact statements will be heard on 20 May when Farrell will receive the mandatory life sentence for murder and will also be sentenced for robbery.
The 44-year-old died from a stab wound to the chest after confronting Farrell, who was carrying out a robbery at Brauders newsagents in Arklow.
Farrell told gardaí it was an accident and he had never meant for any of it to happen.
