Arqit's quantum-linked revenue dips to $355,000 - $380,000. Arqit Quantum Inc. reported revenue between $355,000 and $380,000 for the second half of fiscal year 2026, a decrease from the $463,000 earned in the same period last year, despite securing seven new contracts. The company attributes this decline to an issue with a Middle Eastern customer whose obligations were impacted by geopolitical events in the region. Full fiscal year revenue reached $975,000 to $1,000,000, while Arqit maintains a cash reserve of approximately $51 million as of September 30, 2026. Arqit Quantum Inc. This growth stemmed from revenue recognition linked to previously signed contracts and the new agreements finalized in the period, indicating a continued, if uneven, expansion of its customer base. A contract with a customer in the Middle East significantly impacted second-half revenue, leading to a cessation of revenue recognition due to the customer's inability to meet its obligations. The company stated that revenue recognition is contingent on successful product delivery and the assumption that customers will maintain their contractual commitments without cancellation, delay, or amendment. Arqit's Encryption Intelligence platform, a cryptographic inventory solution, is expected to drive customer engagement in fiscal year 2027 following its commercial launch earlier in 2026. Arqit signed three contracts for Encryption Intelligence in the second half of the fiscal period, with revenue recognition either beginning late in the period or commencing in the first quarter of the next fiscal year. Renewals and expansions of two existing contracts also contributed to the company's financial performance, demonstrating a degree of customer retention, the company says. On October 6, 2026, following the close of the fiscal year, Arqit secured a contract as part of a winning consortium to provide secure networking services to NATO, a one-year agreement with two annual renewal options. As of September 30, 2026, Arqit held approximately $51 million in cash and cash equivalents, providing a financial buffer even as revenue growth remains moderate. The preliminary financial results are based on management's unaudited analysis and are subject to potential adjustments during the completion of financial reporting and review by the company's independent accounting firm. The company stated that during the course of the Company's second half and full fiscal year closing procedures and independent accountant review process, including the finalization of its financial statements for and as of the period ended September 30, 2026, the Company may identify items that would require it to make adjustments, which may be material to the information presented above. The company anticipates reporting complete results in December 2026, followed by a conference call to discuss the findings in detail.

Arqit revenue nearly doubles to $1 million

Babcock and Arqit demonstrate quantum-safe encryption for defence communications. Insider Brief * Babcock and Arqit demonstrated secure transmission of scenario data between two sites at DVD 2026 using Arqit's encryption technology. * The demonstration transferred data from Millbrook to Babcock's Ground Deployed Advanced Mortar System through a layered encryption network without physical inline encryptors. * The demonstration follows an MoU between Babcock and Arqit covering potential collaboration on secure networking, systems integration, digital engineering and cryptographic technologies. PRESS RELEASE - Babcock International Group (Babcock), the defence company, has demonstrated its systems integration expertise by securely transferring scenario data using advanced encryption technology from Arqit Quantum Inc, a global leader in quantum-safe encryption, helping safeguard sensitive information from future cyber threats. Data was collected at one site in Millbrook at DVD 2026, encrypted by Arqit software and securely transmitted to Babcock's Ground Deployed Advanced Mortar System (GDAMS), located at another site at the event. It demonstrated how critical operational information could be exchanged securely in a layered encryption network between a headquarters and a deployed platform in a contested environment, enabling rapid and better-informed decision-making on the battlefield without the use of physical inline encryptors. The demonstration follows the signing of a Memorandum of Understanding (MoU) between both parties to explore how Babcock's capabilities in mission systems, systems integration, digital engineering and through-life support can be combined with Arqit's expertise in cyber security, cryptographic technologies and secure networking. As a systems integration and secure communications expert, Babcock brings together best-in-class technologies to create secure end-to-end communications networks across a variety of Internet Protocol (IP) bearers, including 4G/5G, Wi-Fi and satcom, alongside legacy tactical and new MANET radios. The resulting network can be integrated across a wide range of crewed and uncrewed land, maritime and air platforms. The demonstration also showcased the role of Babcock's GDAMS within a digitally connected battlefield. Based on the proven ST Engineering mortar design, GDAMS combines mobile, network-enabled firepower with digital integration, enabling faster target engagement. Louise Atkinson, Chief Executive, Babcock's Land and Mission Systems business, said: "Armed forces need confidence their critical data can be transmitted quickly, reliably and securely, keeping sensitive information protected at all times. "As technology evolves, so do cyber threats, and the emergence of quantum computing will challenge many of today's encryption methods. We've demonstrated how we can integrate best-in-class technologies to create resilient and secure communications networks that help protect operational data against future quantum-enabled threats." Paul Feenan, Arqit General Manager for Government & Defence, added: "Modern operations require assured secure networks capable of working across multiple communication bearers. Arqit's software-defined encryption, partnered with Babcock's state of the art Advanced Layered System Architecture, can be deployed across networks from core to edge, enabling customers to keep intelligence and battlefield data secure against current and future threats."
