Arqit Quantum Inc. Announces Financial Results for First Half of Fiscal Year 2025

LONDON, May 22, 2025 (GLOBE NEWSWIRE) — Arqit Quantum Inc. (Nasdaq: ARQQ) (“Arqit” or the “Company”), a global leader in quantum-safe encryption, announces financial results for the first half of fiscal year 2025.

Consistent with management’s preliminary assessment of the expected range of revenue which was announced 4 April 2025, reported revenue for the first half period ended 31 March 2025 was $67,000.
As previously announced, Arqit was awarded a multi-year enterprise license contract in the EMEA region for a government end user, which was signed prior to the end of the 2024 fiscal year. Revenue generation was expected to commence early in the first half of fiscal year 2025. However, due to end customer delay, revenue generation did not commence until late March, adversely affecting revenue for the period. The original terms of the contract remain in effect and represent a multi-year enterprise license that is expected to result in seven figures in annual recurring revenue in total.
Revenue for the first half of fiscal year 2025 was generated from 6 contracts. Two of the contracts which generated revenue during the period are multi-year contracts representing annually recurring revenue. Both contracts only commenced revenue generation immediately before the end of the fiscal period. Generally, Arqit’s go-to-market strategy is to sell software licenses to leading network operators, technology vendors and system integrators which in turn are sold to their end customers. Such a strategy is commonly called a B-2-B-2-B business model. Arqit’s initial license sale is for a defined use of its Arqit SKA-Platform^TM (symmetric key agreement encryption solution). Arqit expects initial licenses to grow as licensees successfully sell quantum-safe cybersecurity solutions enabled by Arqit to their end customers.
During the first half of fiscal year 2025, Arqit engaged in or completed demonstration and test activity with 6 telecom network operators and 17 other commercial enterprises and government related parties. Such activity is the initial step in the process toward potential licensing of the Arqit SKA- Platform^TM solution.
For the six months ended 31 March 2025, Arqit’s operating costs averaged $2.4 million per month.
The Company ended the period with cash and cash equivalents of $24.8 million as of 31 March 2025.

Recent Important Developments

At the end of or shortly after the first half of the 2025 fiscal period, important developments occurred which merit highlighting.

On 28 March, Arqit signed a contract associated with Arqit’s symmetric key agreement software embedded into a solution sold to the U.S. Department of Defense (DoD) for a funded program of record. The solution is in partnership with a large IT vendor to the DoD and was sold through one of Arqit’s established government sales channels. More details regarding the contract will be forthcoming. This is an important milestone for the Company as the contract represents Arqit’s first win with the DoD. The U.S. Department of Defense represents a significant market opportunity for Arqit. The Company believes that being compliant with the U.S. National Security Agency’s (NSA) Commercial Solutions for Classified (CSfC) program and now on a DoD program of record is validating as Arqit pursues additional opportunities in this critical target market.
On 31 March, the Company signed a contract to integrate Arqit’s cryptographic technology into the enterprise and government security solutions of a large IT solutions provider. Arqit’s partner will create a sovereign capability securing edge, remote and deployed communications in mission-critical environments. Through our partner, Arqit sees opportunities for penetrating multiple vertical markets and geographies, particularly European government and defence markets.
Arqit announced on 8 April that it had signed shortly before the close of the fiscal period a three year contract with a Tier 1 network operator that operates in 32 countries, providing secure digital infrastructure, with a fibre backbone spanning over 600,000 kilometres. The Company’s quantum-safe Arqit NetworkSecure™ technology will be deployed as part of the telecom network operator’s Network-as-a-Service (NaaS) suite which is now available for order by enterprises and governments. The network operator is already engaged with three significant end customers for the service.
The contract validates Arqit’s focus on the telecom networking sector as a key vertical market. It also provides a blueprint for the 10 telecom network operators with whom Arqit has been or is engaged in demonstration and test activity over the past twelve months. While it took approximately 12 months from initial engagement to commercialization of this contact, Arqit expects subsequent timelines with prospective telecom network operators to compress as a result of the experience.

On 28 April, Arqit announced that the benefits of its quantum-safe Arqit NetworkSecure^TM technology has been delivered to secure confidential computing. In collaboration with Intel, Arqit NetworkSecure^TM running inside a Trusted Domain enclave created by Intel TDX brings the benefits of quantum-safe symmetric key security to sensitive workloads at the chip level.

Arqit’s leadership in mobile communications security innovation has been recognized with industry awards. The collaboration highlights Arqit’s compliance with the NSA’s CSfC security standards which is essential to address the U.S. National Security and Defence markets.

Management Commentary

In reporting fiscal year 2024 results, Arqit emphasized messages including increased market awareness of quantum computing and the threat it poses; the Company’s focus on the most actionable revenue opportunities, particularly in telecom and defence vertical markets; alignment of internal processes and resources to meet customer fulfilment and control costs. The first half of fiscal year 2025 has seen the realization of these messages.

The pace of development of quantum computing is accelerating. Significant public and private capital has been invested in development of the technology and the result of that investment is manifesting itself. Since late 2024, leading technology firms such as Microsoft, Google and Amazon have, respectively, announced development of quantum computing chips with advanced computational power. Quantum computer developers such as Rigetti, D-wave and IBM are announcing continual increases in computational power and error correction of their respective computers. While timing of a quantum computer at scale is uncertain, there is no doubt about the resources and effort being put toward that end.

The threat which a quantum computer at scale poses to current cryptographic security is increasingly recognized. Arqit is currently experiencing high levels of inquiry about the Arqit SKA-Platform^TM. Foot traffic at Arqit’s stand at the RSA 2025 Conference in May, the world largest cybersecurity conference, was significant. Technology companies, network operators, enterprises and governments are understanding that Q Day is coming and that cybersecurity enhancements are required. The market is moving toward Arqit with increased pace.

Arqit is focused on pursuing the most actionable opportunities, both vertical markets and specific potential customers, to drive growth in revenue. Operating within the Company’s finite resources, Arqit has made positive headway in converting demonstration and test engagements with telecom network operators and defence organizations into multi-year contracts, as evidenced by announcements of contracts with a Tier 1 telecom network operator and the U.S. DoD. The Company has multiple additional contract opportunities in these key vertical markets moving through the demonstration and test cycle. The company expect to convert more such opportunities to contracts in this fiscal year.

Beyond telecom networks and defence, other market opportunities include but are not limited to:

Arqit envisions the application of its symmetric key cryptographic solution across data in process, data in transit and data at rest. The Company has demonstrated capability to provide quantum-safe security for data in all three states. Arqit’s goal is to have monetizable solutions addressing data in each of these states. However, it remains focused on converting actionable opportunities which will result in near term revenue growth.

The Company has realigned personnel to meet its current stage of development. Increases in customer fulfilment and support roles have occurred. Likewise, increasing the number of sales roles has been a hiring emphasis. Driving revenue is important but so too is the efficient fulfilment of executed contracts. Despite growth in personnel in these areas, overall headcount of 72 as of 31 March 2025 was below budgeted headcount of 83 employees. Likewise, monthly operating costs averaged $2.4 million, in line with budgeted costs. Prioritizing the utilization of resources and disciplined cost control remain key objectives of management.

Commenting, Andy Leaver, Chief Executive Officer said: “2025 has been designated by the United Nations as the “International Year of Quantum Science and Technology” in recognition of the role quantum mechanics has played and will play in society. We are seeing the impact, positive and potentially the threat, of quantum physics playing out in real time with the development of quantum computing. Q Day is coming and governments and enterprises need to be prepared to embrace the benefits of quantum computing and safeguard against the threat which it poses.

Arqit’s symmetric key agreement cryptographic solution is increasingly seen as a leading cybersecurity antidote to the quantum threat. Important contract wins in the telecom and defence markets, and recent joint development with leading technology partners of innovative quantum-safe solutions for data networking, mobile communications and confidential computing demonstrate Arqit is at the forefront of radical cryptographic advancement.

We will continue to be focused on driving opportunities through our sales pipeline to grow revenue. The strength of our technology will lead our success, but prioritization, focus and cost control are key to driving value creation for all our stakeholders.”
