Calnex Solutions PLC (CLX:AIM) delivers a steady investor update highlighting resilient company performance, disciplined cost control, and continued progress across its test-and-measurement portfolio serving telecoms, cloud, data centre, and government markets. Management reported first-half FY26 revenue of £8m, up from £7.3m, supported by strong product demand in the US government and defence sector, growing traction in cloud and data-centre applications, and ongoing momentum from its market-leading 800G Paragon Neo platform. Despite subdued telecoms spending, the company notes rising customer engagement and early signs of improvement, while also advancing its next-generation 1.6Tbps product roadmap to sustain long-term growth. Gross margins strengthened to 76%, EBITDA and loss before tax both improved, and cash remained healthy at over £10m, with positive working-capital movements and expected H2 cash generation. Calnex continues to build its global sales infrastructure, transitioning from its historic Syant channel to a diversified partner network, adding US federal-market specialists, and expanding strategic partnerships including its newly formalised collaboration with Viavi. The company reiterated confidence in its growth strategy, supported by robust demand across LabSync, Network Sync, and network-assurance solutions, an expanding order pipeline, disciplined R&D investment, and strong positioning within key growth markets such as AI-driven cloud infrastructure, hyperscale data centres, and timing-critical network applications.
