Current Trading & Outlook
· Q1 2026 has started strongly, significantly exceeding Q1 2025 which was a challenging quarter
· Management remains positive in the Group’s ability to deliver sustained ARR growth, alongside continued migration to a subscription-based sale model which further improves revenue predictability, noting that contract structures will be customer led
· Global cybersecurity threats continue to drive further demand for Corero’s market leading products
· The Board remains confident in the prospects of the Group to deliver ongoing progress, notwithstanding ongoing global economic uncertainty
Carl Herberger, CEO of Corero, said:
“I am pleased with the performance of the business, especially in the second half where we delivered particularly strong sales growth. Our ongoing transition to a subscription-based sales model gathered pace in the year, and further investment in R&D and new product development has underpinned our sales growth with both new and existing customers.
The DDoS market has remained buoyant, fuelled by ongoing cyber threats and increasing regulatory obligations. High-profile attacks on companies, especially across Europe, have reinforced the value of comprehensive DDoS solutions, further driving demand for our products and services from partners and customers.
Corero remains well placed for future growth, with our sales and marketing efforts generating strong sales growth in the current financial year.”
