Company Descriptions
Gamma is a leading provider of Unified Communications as a Service (UCaaS) into the UK, Dutch, Spanish and German business markets (having built its European operations through acquisition), supplying communication solutions via its extensive network of trusted channel partners and also directly. Its combination of network investment, a digital-first approach and in-house development skills has enabled Gamma to develop a comprehensive portfolio of communications services with a significant amount of intellectual property. It offers flexible solutions and enjoys a collaborative culture with specialist expertise of business communications. Its connected communications offering relies on sophisticated, dependable and secure products and services. Gamma provides end-to-end control and technical integration of network services.
Investment Summary
Gamma is active in an exciting growth area of the telecoms market and its strategic positioning allows it to compete strongly. The group has now made six acquisitions that have established its presence in the Netherlands, Spain and Germany. We note that, together, the Cloud PBX markets in Spain, Netherlands and Germany represent an opportunity more than three times the size of that of the UK, representing ideal opportunities for Gamma. We also anticipate that the group will further expand its European presence via more acquisitions. Meanwhile, we expect Gamma to continue to benefit from its resilience in the current operating environment through a range of growth opportunities in both the UK and European unified communications markets.
