Arqit Quantum Inc Stock Price, News & Analysis

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.

Company CEO Andy Leaver and CFO Nick Pointon will host the call. A live webcast will be available on the company’s News & Events page at ir.arqit.uk and a replay will be posted for a limited time. Phone access requires registration via the provided link; participants are encouraged to dial in 15 minutes early.

Arqit (NASDAQ: ARQQ) launched SKA Central Controller (SKA-CC) on Nov 11, 2025, a crypto‑agile, low‑footprint software platform designed to provide quantum‑safe symmetric key management across wireline, mobile, cloud and AI environments.

SKA-CC generates dynamic symmetric keys for endpoint authentication and encrypted VPN tunnels, removes reliance on long‑lived pre‑shared keys or PKI, and supports use cases from Optical Layer 1 to APIs and private 5G—targeting Telco and Defense Managed Service Providers to enable quantum‑safe NaaS and mobile VPNs.

Arqit Quantum (Nasdaq: ARQQ) provided preliminary unaudited results for the second half and full fiscal year ended 30 September 2025. Management expects H2 revenue of $460,000–$470,000 and full-year revenue of $525,000–$535,000. Cash and cash equivalents were approximately $36.9 million as of 30 September 2025. Revenue growth reflected recognition of new contracts and the March 2025 start of revenue recognition under a previously announced multi-year enterprise license in EMEA for a government end user. The company has executed contracts expected to generate approximately $1.2 million in fiscal 2026. Results are preliminary, unaudited, and subject to adjustment; final results and a conference call are expected in December 2025.

Arqit Quantum (NASDAQ:ARQQ) announced that Fabric Networks has purchased a commercial Private Instance (PI) license for its NetworkSecure™ platform. The agreement enables Fabric Networks to deploy quantum-safe networks at scale across its diverse infrastructure, which includes fiber-optic networks, private LTE/5G, pipeline telemetry, and managed network services.

Fabric Networks will implement Arqit's Symmetric Key Agreement (SKA-Platform™) technology to protect critical data from cybercriminals and nation-state actors. The solution will serve various sectors including rural communities, smart cities, educational institutions, healthcare facilities, and resource industries.

Arqit Quantum (Nasdaq: ARQQ) has been selected by the National Cyber Security Centre (NCSC) to participate in their Post-Quantum Cryptography (PQC) Pilot program. The company will provide Discovery and Migration Planning services through its Encryption Intelligence product, helping organizations transition to quantum-safe technologies.

The NCSC initiative aims to prepare organizations for PQC migration, with recommendations to have cryptographic discovery and migration roadmaps in place immediately. Priority systems should be migrated by 2030, with full migration completed by 2035. This selection follows Arqit's strategic acquisition of Ampliphae's encryption risk advisory and analytics technology, strengthening their capabilities in quantum-safe security solutions.

Arqit Quantum (NASDAQ:ARQQ), a quantum-safe encryption leader, has been selected to join Tomorrow Street's Scaleup X programme for 2025. Tomorrow Street, Vodafone's Luxembourg-based innovation centre, will provide Arqit access to its global network and ecosystem.

Through this collaboration, Arqit will explore opportunities to implement its Symmetric Key Agreement (SKA-Platform™) and NetworkSecure™ solutions across Vodafone's ecosystem, focusing on securing critical communications and data against quantum computing threats. The partnership aligns with Arqit's strategy to expand its quantum-safe network security solutions in telecoms, critical infrastructure, and enterprise sectors.
