Arqit Quantum Inc.

For the first half of fiscal 2026, revenue was $623,000 versus $67,000 in the same period of fiscal 2025. Operating loss was $33.7 million versus a loss of $20.0 million, and loss before tax from continuing operations was $33.1 million versus $19.5 million. Administrative expenses rose to $33.9 million from $20.2 million, including a $12.7 million noncash share-based compensation charge versus about $0.8 million to $2.0 million in the prior period. Cash and cash equivalents were $28.9 million at March 31 and $35.9 million as of May 20. Management said the company has more than 14 months of runway and expects about $13.5 million from heavily in-the-money warrants that expire in September 2026. No formal next-quarter or full-year revenue guidance was provided; management instead said it expects additional contract wins during the balance of the fiscal year and further progress in the second half.

Andrew Leaver’s message was that the market is moving from awareness to action on post-quantum cryptography, and Arqit’s products are positioned to help organizations assess risk and migrate. He emphasized that major industry voices and recent quantum-computing research are compressing the expected migration timeline, making urgency a central theme of the call. His tone was constructive and confident, repeatedly describing momentum as building across telecom, government, defense, and infrastructure customers.

The CFO said first-half revenue of $623,000 reflected more contract execution than a year ago, with 11 contracts in the period versus 6 in the prior-year period. He noted administrative expenses increased to $33.9 million from $20.2 million, driven by higher employee-related costs and share-based compensation, and that the period included a $12.7 million noncash SBC charge. He also said cash was $28.9 million at March 31 and $35.9 million on May 20, with more than 14 months of runway and about $13.5 million of additional liquidity expected from in-the-money warrants.

Analysts focused on two issues: whether the industry has reached a real inflection point in quantum-security adoption, and what near-term milestones could trigger broader customer action. Leaver answered that there may not be a single event when encryption is 'broken,' but rather a growing recognition that migration is a larger, organization-wide effort that starts with visibility and planning. On financing, management said the current cash balance and warrant proceeds leave them comfortable meeting commercial objectives, while also clarifying that there are additional warrants outstanding beyond the September 2026 tranche.
