Having made two UK acquisitions in 2021 in the form of Blue Chip and The ICC Group, this US-based datacentre solutions provider integrated the two conquests in June 2022. Its local revenues totalled £52.4m in a slightly truncated calendar 2021, according to accounts filed by a newly formed EMEA holding company. That compares to the £53.5m IBM maintenance specialist Blue Chip turned over in its fiscal 2020. The ICC Group contributed four months to the 2021 total.
