Arqit (Nasdaq: ARQQ) on January 22, 2026 launched Encryption Intelligence, a commercial product that provides automated cryptographic discovery, continuous monitoring and risk prioritisation to support migration to post-quantum cryptography (PQC).
Encryption Intelligence aims to expose obsolete or weak encryption across networks, applications and cloud services, accelerate secure PQC migration planning, and provide ongoing optimisation for compliance. Arqit was selected to participate in the UK National Cyber Security Centre Post-Quantum Cryptography Pilot, which the company says validates its discovery and migration planning methodology.
Arqit Quantum (Nasdaq: ARQQ) reported fiscal year 2025 revenue of $530,000 for the year ended September 30, 2025, with $463,000 in the second half versus $67,000 in the first half.
Revenue arose from seven contracts (two multi-year, recurring) and the company has executed contracts expected to generate approximately $1.2 million in fiscal 2026. In the two months after year‑end Arqit signed 12 demonstration and test licenses. Operating costs averaged $2.5 million per month and cash and cash equivalents were approximately $36.9 million as of September 30, 2025. In May Arqit acquired Ampliphae’s product portfolio and innovations team to add Encryption Intelligence and AI analytics.
Arqit (NASDAQ: ARQQ) and Sparkle announced on December 3, 2025 a successful proof of concept demonstrating quantum-resistant encryption embedded at the optical transport layer across Sparkle’s metropolitan ring in Athens.
The POC applied Arqit SKA-Platform™ encryption directly on optical transponders (L1), secured multi-100G optical links end-to-end, and required no physical changes to optical hardware. Keys were injected from VM and universal CPE appliances via an ETSI14 interface and managed through an orchestration platform. The companies present the result as a scalable, low-disruption approach to protect high-capacity networks against future quantum threats.
Arqit Quantum (NASDAQ:ARQQ) will report financial results for the fiscal year ended September 30, 2025 and hold a conference call on Tuesday, December 9, 2025 at 11:00 a.m. ET.
