Collabro won Britain's Got Talent in 2014 and were quickly signed up for a record deal.
They released two Top 5 albums and went on tour but earlier this year lost one of the group when Richard Hadfield decided to quit.
Jack Pack meanwhile made the final in 2015 and were also signed, releasing a Top 10 album last September.
However there are set to be no more releases from either group with Syco.
But fans needn't worry as other labels are said to be interested in signing them both up with talks already under way.
A source told the Daily Star newspaper: “The boys are obviously gutted not to be with Syco any longer, especially as they’ve achieved great success together.
“But they are excited about the future. They are already in talks with a few labels and have plans to do more tours in Japan, Canada and America.”
Britain's Got Talent will return to ITV next year for its eleventh series.
