BDO in Jersey has purchased the Channel Islands technology business C5 Alliance Group.
C5, which provides technology services to businesses across the Channel Islands, was established 19 years ago and employs 200 people. Its growth has included the acquisition of Cronus Consulting in 2012, ITEX Holdings in 2013 and Altius CI in 2016.
For BDO, the move follows the acquisitions of Jersey consultancy businesses Greenlight CI and Sator Regulatory Consulting in 2016.
Matthew Corbin, CEO of BDO in Jersey, said: "This acquisition consolidates two businesses in their respective fields and creates a unified firm providing strategy, consulting, digital, technology and managed services.
"Our clients are competing in an increasingly complex business environment dominated by fast-paced technological, fiscal and regulatory change. Extending our professional services capabilities in the area of technology ensures we continue to align our services to the needs of our clients."
The acquisition takes BDO's staff count to more than 350 across the Channel Islands.
At the time of going to press, BL was awaiting clarification whether C5 would retain its current branding.
