CORERO NETWORK SECURITY PLC - Half Year Results for the six months ended 30 June 2026

Corero Network Security PLC delivered strong H1 2026 financial results, with revenue increasing 42% year-on-year to $15.5 million and annual recurring revenue (ARR) reaching $24.1 million, up 12%. The cybersecurity specialist also achieved a 93% gross margin and maintained a 96% customer renewal rate, with revenue growth driving significant operating leverage following an EBITDA loss in H1 2025. Commercial momentum remained strong, including major contract wins with service providers in Brazil, the US and UK, alongside expansion into the rapidly growing AI data centre and neocloud markets. Post-period wins included an initial $1.4 million contract with a major US telecoms provider and a five-year $3.4 million agreement with a Tier 1 UK operator. Corero’s growth strategy is increasingly focused on evolving from a DDoS protection specialist into a broader cyber resiliency platform, supported by an expanded product portfolio spanning traffic observability, API protection, performance monitoring and zero trust. Management expects to exceed market expectations for FY2026 revenue of approximately $29.2 million and significantly exceed EBITDA expectations of around $3.3 million, supported by a strengthened sales pipeline, new product traction and geographic expansion. With growing demand from AI infrastructure, regulatory resilience requirements and increasingly sophisticated cyber threats, Corero believes its differentiated technology and expanding Tier 1 customer base position the business for continued revenue, ARR and cash flow growth into 2027.
