FY26 Trading Update and Notice of Results

Double digit revenue growth and improved profitability in FY26

Increasingly diversified product offering and strengthened sales & marketing team provide confident outlook

Calnex Solutions plc (AIM: CLX), a leading provider of test and measurement solutions for the global telecommunications, cloud computing & datacentres, and government & defence markets, is pleased to provide an update on trading for the year ended 31 March 2026 ("FY26") and the outlook for FY27 and FY28.

Calnex has made good progress in FY26, trading slightly ahead of market expectations, delivering double-digit revenue growth and improved profitability, while continuing to invest in its long-term strategy.

The Group expects revenue to have increased by approximately 19% to £21.9m (FY25: £18.4m). Gross margins have remained strong, which has contributed to an improvement in profitability for the year. The Group maintained a strong balance sheet, with cash as at 31 March 2026 of £9.3m (31 March 2025: £10.9m), with a further c£3m of customer receipts expected in the early months of FY27 due to the phasing of shipments through Q4.

Diversification across the cloud computing & datacentres and government & defence markets continued to gain traction in FY26 and, against a backdrop of a stable telecoms market, supports confidence in continued growth in FY27 and FY28.

Channel and operational enhancements continued to strengthen market access during the year. The Group expanded its global partner network, onboarded new North American partners and increased its focus on partner enablement to enhance sales coverage, particularly in higher growth markets.

The progress achieved in FY26 provides a strong foundation for continued profitable growth through FY27 and FY28. FY27 will be a year of targeted investment directed towards key product launches and the development of the market and customer relationships which will underpin future growth. The Board's confidence is based on a number of key factors that will position the Group for accelerated growth in FY28 as these initiatives in rapidly growing markets are launched and commercialised.

·    The level of investment by hyperscalers in AI capacity is well-documented and Calnex's network emulation SNE product, currently progressing through a successful discovery phase, is attracting keen interest in this market, with anticipated revenue generation in late FY27.

·    Calnex's Sentry product is a market-leader in the datacentre market, with significant sales to a hyperscaler achieved in recent years and next generation product offering strong forward potential across the global datacentre industry.

·    Our Paragon Neo-S 800 Gb/s synchronisation testing product has proved to be successful in telecoms and datacentre markets and we are investing in the development of the next evolution, the 1.6Tb/S product, for launch in FY28 and which is already attracting strong prospective customer interest.

·    In November 2025, Calnex agreed a partnership with VIAVI Solutions Inc, a global provider of solutions to the telecoms, datacentre and defence sectors in which Calnex is also active. The partnership is already delivering value for customers, and we see significant future potential strengthening our Go To Market footprint.

Calnex has maintained its key position in the global telecoms market and is well-placed for growth in that core market when demand increases.

Notice of Results

The Company expects to announce its audited results for FY26 on 26 May 2026.

Tommy Cook, Chief Executive Officer and founder of Calnex, said: "I am pleased to report on a good performance in FY26, our 20^th year of operations, delivered against a challenging global macroeconomic backdrop. We achieved double digit revenue growth and improved profitability, reflecting the successful diversification beyond our core telecoms heritage. We are seeing growing traction across cloud computing, datacentres, government and defence and are continuing with important development programmes to address these growth markets.

With a strong balance sheet, expanding partner network, increasingly developed and diversified offering, and strengthened sales and marketing capability we are well positioned to build on this momentum and deliver sustainable growth in FY27 and beyond."
