Reported revenue and cash position

Based on management’s preliminary unaudited analysis, Arqit expects revenue for the second half period ended 30 September 2026 of approximately $355,000 to $380,000, and for the full fiscal year ended 30 September 2026 revenue is expected to be $975,000 to $1,000,000. The company reported cash and cash equivalents were approximately $51 million as of 30 September 2026. The company also compared the second half and full year revenue to fiscal year 2025 figures.

Revenue drivers and contract events

Arqit reported growth in fiscal year 2026 revenue versus fiscal year 2025 arising from multiple factors including revenue recognition associated with delivery under contracts signed prior to the commencement of the period and revenue recognition associated with 7 new contracts signed in the period. The second half revenue was adversely affected by cessation of revenue recognition under a material contract with a customer in the Middle East due to impacts on the customer’s ability to fulfill contractual obligations. The company noted contract activity including 3 contracts for Encryption Intelligence signed in the second half and a post-period contract as part of a winning bidding consortium to provide secure networking services to NATO, to be delivered as a 1 year contract with 2 annual renewal options.

Audit qualification and forward-looking caution

Arqit stated the preliminary financial results are based on management’s preliminary unaudited analysis and that the Company has not completed its financial statement reporting and the Company’s independent accounting firm has not reviewed the preliminary financial data. The company disclosed that during closing procedures and independent accountant review the Company may identify items that would require it to make adjustments, which may be material to the information presented, and described the estimates as forward-looking information subject to risks and uncertainties.

Why this may matter (inference)

The company’s disclosed preliminary revenue ranges, contract wins, and the reported $51 million cash and cash equivalents balance provide a snapshot of near-term revenue recognition dynamics and available liquidity ahead of audited results and a scheduled complete reporting in December 2026. The post-period NATO contract and the stated commercialization of Encryption Intelligence may shape revenue recognition timing in fiscal year 2027, subject to contract delivery and customer performance.

What remains uncertain

• The financial figures provided are preliminary and unaudited; Arqit states the Company has not completed its financial statement reporting and its independent accounting firm has not reviewed the preliminary financial data, and adjustments identified during closing procedures may be material.
• Revenue recognition described by the company depends on successful delivery under contract terms and assumes customers will not cancel, delay or amend the terms of their contracts.
• Statements about future revenue effects from Encryption Intelligence commercialization and the NATO contract are forward-looking as presented by the company and not independently verified in this release.
