Calnex Solutions – executive interview

In this interview, Tommy Cook, Calnex Solutions founder and CEO, discusses how the company’s synchronisation and emulation solutions play an essential role in validating the performance of critical network infrastructure. He highlights the product roadmap as interface speeds increase, with demand increasingly driven by AI-related data centre build-outs alongside ongoing telecom requirements and a growing defence opportunity. CFO Ashleigh Greenan describes a model led by hardware and software sales, complemented by growing support and maintenance income (shifting towards an c 80/20 split), and explains that the group’s capital allocation prioritises maintaining a strong, resilient balance sheet with surplus cash, while keeping some capacity for small, bolt-on M&A without taking on leverage.

Calnex Solutions designs, produces and markets test and measurement instrumentation and software used to validate the performance of critical network infrastructure. Its solutions support network synchronisation (timing) and network emulation testing for telecoms and cloud/data-centre environments, sold internationally to equipment vendors, service providers and other network operators.
