Arqit Quantum (Nasdaq: ARQQ) reported first-half fiscal 2026 revenue of $623,000 as of 31 March 2026, up from $67,000 a year earlier and $463,000 in second-half 2025.
The company signed 11 revenue-generating contracts, kept operating costs to about $2.6 million per month, and ended the period with $28.9 million in cash, rising to $35.9 million by 20 May 2026.
Arqit launched its Encryption Intelligence PQC migration product, executed its first related contract, expanded collaborations with Intel, 6WIND and RAD, and saw a defence-sector partner renew and increase its contract by nearly 90%.
Arqit Quantum (NASDAQ:ARQQ) will report financial results for the six months ending March 31, 2026, on Thursday, May 21, 2026. Management will host an earnings conference call at 11:00 a.m. ET / 8:00 a.m. PT with CEO Andy Leaver and CFO Nick Pointon.
A live webcast and limited-time replay will be available on the company’s investor relations site at ir.arqit.uk. Phone participants must register online to receive dial-in details and are encouraged to join 15 minutes early.
Arqit (Nasdaq: ARQQ) has been selected as a Scaleup Partner in Tomorrow Street's portfolio, becoming the first quantum security company in the group on April 16, 2026. The move follows Arqit's participation in Tomorrow Street's 2025 Scaleup X programme and highlights demand for post-quantum security solutions.
Through Tomorrow Street, Arqit will have access to ecosystem partners to scale NetworkSecure™ capabilities, help organizations assess cryptographic risk, and plan PQC migration and data sovereignty strategies.
Arqit Quantum (Nasdaq: ARQQ) provided select preliminary, unaudited results for H1 FY2026 ended March 31, 2026. Management expects H1 revenue of approximately $620,000–$630,000 versus $67,000 in H1 FY2025. Cash and cash equivalents were $28.9 million as of March 31, 2026.
Revenue growth reflects recognition from deliveries under preexisting contracts and three new contracts signed during the period. Results are preliminary, unaudited, and may change during final close and independent review.
Arqit (Nasdaq: ARQQ) and RAD announced a collaboration on March 2, 2026 to deliver a joint quantum-safe encryption solution for telcos. The integration pairs Arqit’s NetworkSecure™ key generation with RAD’s ETX Carrier Edge platform to enable site-to-site, site-to-cloud VPNs and DCI.
The solution targets near-term risks such as "Harvest Now, Decrypt Later" attacks and the long-term threat from quantum computing by offering a crypto-agile, hybrid post-quantum approach, according to the company.
Arqit (Nasdaq: ARQQ) and Intel-sponsored research finds 62% of respondents cite data sovereignty and privacy risks as the top factor slowing AI projects in the public cloud. The survey also reports 16% of organisations have no access to facilities with guaranteed data sovereignty and only 8% have sovereign edge environments.
The research, to be unveiled at MWC Barcelona 2026, shows urgent AI demand but rollout delays: 69% rate AI for network safety as urgent, yet 60% are still testing or have not deployed AI for security. 80% expect to use confidential computing within 12 months.
Arqit (NASDAQ: ARQQ) announced that its quantum-safe encryption software is now available pre-installed inside an Intel TDX trusted execution environment on Intel NetSec Accelerator Reference Design-based cards, enabling confidential compute for trusted workloads, networks, and agents.
The solution creates on-demand, non‑stored quantum-safe keys consumed inside the TEE, protects data at line speed with hardware acceleration, and targets telecom and critical national infrastructure use cases. Arqit and Intel will demonstrate the technology at MWC Barcelona 2026 starting March 2, 2026.
Arqit (Nasdaq: ARQQ) and 6WIND announced a strategic collaboration on Feb 19, 2026 to integrate Arqit’s NetworkSecure™ quantum-safe key generation with 6WIND’s Virtual Service Router.
The joint solution targets scalable, on-device quantum-safe IPsec VPN services for telcos, enterprises, uCPE and virtualised cloud deployments.
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.
