The growing firm, which provides communications solutions to leading medical companies across the UK, Switzerland and the US, is set to use the investment to further expand its international presence through a series of acquisitions.
The secondary buyout deal sees current owner YFM Equity Partners exit the company with a two times return on its original investment.
With Fishawack’s turnover has trebled to £10m since it was sold to YFM Equity Partners in 2008, it is hoped that the firm will see continued growth under the management team of founding directors Oliver Dennis and Dominic Miller, as well as managing director Gail Flockhart and operations director Rachel Davies, who will continue to lead the business.
Commented on the acquisition, which marks GCP’s fifth deal in nine months, Co-founder Oliver Dennis said: “We are really pleased to be working in partnership with GCP and they have a strong track record of helping businesses to deliver on their growth plans.
“We want to continue to build on our market leading position, increase our customer base and expand further internationally. GCP is well placed to help us achieve these goals.”
