You can find reconciliation of these metrics to the company's reported IFRS results in the reconciliation tables provided in today's earnings release. Now, I'll turn the call over to David Williams, the company's Founder, Chairman, and Chief Executive Officer. David? Thank you for joining our fiscal year 2023 earnings call. The year was one of evolution, growth, and challenges for Arqit. Our reported revenues were modest, but that said, much progress has been made in deepening and broadening the foundation for future success, particularly in the expansion of our channel partnerships and specialized applications. Since our strategic pivot in December 2022 to focus on an exclusively software product sold through sales channel partners, there has been encouraging commercial progress in building OEM integrations and distribution partnerships. It takes considerable time for these partnerships to become productive, and so revenue growth from these channels is at an early stage. We hope to see an inflection point in fiscal 2024 as those channel partners' sales initiatives begin to mature. During 2023, we worked hard on the execution of that new strategy through integrations of our software with OEMs and the creation of distributor and reseller channel partnerships. This was a pivot away from a focus previously on direct enterprise sales of a previous product, which involved hardware. Changing our go to market strategy, combined with the pace of activating our new sales channels, results in limited revenues from our products. However, progress in establishing those OEM integrations and channels convinces us that the strategy is correct. Beyond the headline revenue result, there is evidence of material progress in broadening and deepening our business foundations, specifically the growth in our channel partnerships, the development of the suite of specialized applications of our core Symmetric Key Agreement product, and the green shoots of revenue contract activity. There is evidence, for example, in the White House National Security Memorandum of May 4, 2022, and the activity that followed, that government and commercial organizations are moving forward with the switch to new forms of encryption. We also believe that our product is compliant with relevant standards laid down by the NSA in the USA for National Security Agency Commercial Solutions for Classified Symmetric key Management, which has relevance in most markets. When we announced our new go to market strategy in December 2022, we named 5 partners at that time. As of today, we have 15 channel partners, including leading technology OEMs, distributors, and resellers. These channel partners provide Arqit with access to different industry verticals, such as security and financial services and telecoms, and in many cases, our partners offer global market reach. Each new channel partner relationship is further validation by leading market participants of the efficacy of Arqit's Symmetric Key Agreement platform. Each of these relationships offers distribution leverage to Arqit, which creates sales opportunities and reduces Arqit's need for a significant direct sales force. In turn, Arqit provides its channel partners with a differentiated encryption service to offer to their customers that addresses issues with today's encryption architecture and also those presented by the advent of quantum computing. Our differentiated product offering represents incremental sales opportunities for our partners, w e now focus on translating these partnerships into meaningful revenue growth.... Each of our channel partnerships are at different stages of activation. Some are advanced, such as Juniper Networks, where an integrated Juniper Arqit solution has been released for general availability. Others are earlier stage, with additional channel education occurring. In the fiscal year, we generated revenue through six of our channel partners. While the revenue is modest, the increase from sales through two channels in the first half of 2023 to sales through six different channels for the full year is positive momentum. Arqit's foundational product offering included QuantumCloud, a platform as a service for those customers who prefer a multi-tenanted solution, and the QuantumCloud Private Instance for those customers who require private control of their own tech stack. To encourage ease of adoption and to address specific industry verticals, Arqit then undertook the productization of some specialized applications of the QuantumCloud Symmetric Key Agreement platform. Specifically, we created and announced in fiscal 2023, Arqit Network Secure to address network security via firewalls, routers, and other networking devices. Also, Arqit Trade Secure, which addresses digital trade finance, and Arqit Wallet Secure, to address financial transaction compliance and security. We're pleased to say that we now have strong partners for each of these specialized applications. Arqit Network Secure is embedded into certain firewall offerings of Juniper Networks and Fortinet, with integration work with other similar companies underway. We're pleased to say the first sales of Network Secure-enabled firewalls of both channel partners have been executed. We believe this is a significant market opportunity for the company in both the commercial and government markets. As distributors and resellers of Juniper and Fortinet firewalls, who are our partners, such as Carahsoft and Exclusive Networks, become fully activated, we expect commercialization of Arqit Network Secure to gain more traction. The Trade Secure product has benefited from regulatory progress this year. The Electronic Trade Documents Act came into force in the United Kingdom in September 2023, and permits the use of legally recognized digital trade documentation. Digital trade documentation offers benefits to importers of lower administrative costs, faster payment for exports, and lower capital allocation for banks. The supply chain finance market is a large and growing market, and digital transformation is accelerating now as a result of legal clarity. Arqit believes that Trade Secure is the only digital trade documentation product which is fully compliant with ETDA, and provides the added benefits of Symmetric Key Agreement encryption. Arqit's first channel partner to bring Trade Secure to market is Traxpay. Currently, the first trade finance transactions under the Electronic Trade Documents Act using Trade Secure are progressing. We expect to announce them shortly. Arqit has identified and is in discussion with additional potential supply chain finance and banking channel partners to bring Trade Secure to market. Wallet Secure, which provides compliance, analytics, and digital asset security, is our newest specialized application and is targeted towards the financial services industry. Wallet Secure will be offered as part of an existing product offering of a major global financial services company. We expect to announce that arrangement in the near term and have this product offering come online in fiscal 2024. For fiscal 2023, we generated revenue from all of our product offerings that were available to the market, being QuantumCloud, PaaS, QuantumCloud Private Instance, Network Secure, and Trade Secure. In the case of QuantumCloud Private Instance and Network Secure, we have made multiple sales of these products. Again, while the number of revenue transactions is modest, sales across all of our available products is encouraging. To provide Arqit with additional runway to progress the commercialization of its products, we took significant actions in 2023 to improve our capital position and lower our operating costs. The company undertook two offerings of common stock and also placed stock through an at-the-market placement program. We raised $47.7 million in gross proceeds from those offerings during the period. Our cash balance at the end of fiscal year 2023 was $44.5 million. We announced with our first half results and successfully executed a cost reduction action and benefits, which became evident, started in July. Nick will discuss more about this in a moment. Taking cost actions, which included reducing headcounts, are difficult decisions. However, for the stability of the business, they were the correct decisions and give Arqit the best chance to realize the value we see in our groundbreaking symmetric key agreement platform. We believe that the opportunity which our product addresses merits additional patience as we work to further activate our channel partnerships and sign new such relationships. Our product develops stronger, simpler encryption in a manner that Arqit believes meets the requirements of the White House's National Security Memorandum 10, which called for the adoption of enhanced encryption and advocates for symmetric key solutions. Significant technology companies share our view and have become partners. Furthermore, we believe we are unique in having such a solution available today that is compatible with existing protocols and standards and is easy to implement. We believe that we made meaningful progress with the business in 2023, and we're optimistic that our channel partnerships will deliver further improvement in 2024. With that, let me turn the call over to Nick Pointon, our CFO, for his remarks on our financials. Nick? Thank you, David. We announced early in the fiscal year that Arqit was exploring transactions to sell or otherwise monetize its satellite under construction,t he satellite was part of our original technology. As we previously stated, through innovation, our technology stack no longer requires a satellite component and is now entirely software-based, using terrestrial classic computing technology. We have reclassified intangible assets and project development costs related to the satellite and have presented them as discontinued operations according to IFRS 5. Our fiscal 2023 results and 2022 comparisons reflect this new classification. For the 12-month period ended 30th September 2023, we generated $5.6 million in revenue and other operating income from discontinued operations. For the comparable period in 2022, we generated $20.0 million. Revenue from our QuantumCloud product for the period totaled $639,968, generated by seven contracts, representing revenue through six different channel partners. As David noted earlier, we generated revenue from all four products currently available for sale, including multiple sales of QuantumCloud Private Instance and Network Secure. The balance of the fiscal year 2023 revenue was from other operating income from discontinued operations, specifically from our contract with the European Space Agency associated with the satellite development. Future other operating income from our ESA contract is uncertain. For fiscal year 2022, revenue and other operating income from discontinued operations was $20.0 million, of which $7.2 million was revenue from our QuantumCloud product and $12.8 million from our contract with the European Space Agency. Revenue from our Symmetric Key Agreement products for the period was highly concentrated, as $4.7 million of the $77.2 million, or 65%, was from the direct sale of one enterprise license contract with Virgin Orbit. The direct sale of enterprise licenses is no longer our primary focus as a result of our pivot in our go-to-market strategy. The year-over-year decline in revenue from our QuantumCloud product reflects the refocusing of our sales efforts through OEMs, distributors, and resellers. It was a step back to move forward. The 2023 versus 2022 decline in operating income from our ESA contract reflects slower development of the satellite as we contemplated selling or otherwise monetizing the asset. Discussions regarding possible transactions associated with the asset are ongoing, but there can be no assurance that a transaction is consummated. Our administrative expenses equate to operating costs for those more familiar with U.S. GAAP. For fiscal year 2023, our administrative expenses were $55.2 million versus $71.0 million for fiscal year 2022. Lower share-based compensation and foreign exchange loss were the largest drivers of the variance between periods. We announced a cost-saving initiative in May, along with our H1 results. A significant component of the cost actions was a reduction in headcount. Our headcount at the end of H1 was 170 employees. As of September 30th, it was 147. We began to realize the benefits of our cost-saving initiative in July. We have continued to review all areas and functions in pursuit of increased operational and cost efficiency. Administrative expenses for the fiscal year 2023 include a $14.1 million non-cash charge for share-based compensation versus a $21.7 million charge for fiscal year 2022. Operating loss for the fiscal year was $84.4 million versus a loss of $63.8 million fiscal year 2022. The variance in operating loss between periods primarily reflects lower revenue and the reclassification of other operating income as profit from discontinued operations, combined with a $20.3 million impairment on trade receivables and contract assets associated with the Virgin Orbit bankruptcy, and $17.6 million impairment associated with satellite project development costs. We generated a loss before tax from continuing operations of $73.9 million. However, we generated an adjusted loss before tax of $84.7 million, which, in management's view, reflects the underlying business performance once non-cash change in warrant value is deducted from loss before tax. For fiscal year 2022, we generated a profit before tax from continuing operations of $53.4 million and an adjusted loss before tax of $64.0 million. We raised $47.7 million in gross proceeds from the sale of common stock during fiscal year 2023. We issued shares in two registered direct offerings, one in February and one in September. We also placed shares directly into the market through at-the-market issuance program. As a result, we ended the period with a cash balance of $44.5 million versus a cash balance of $48.9 million as of fiscal year-end, September 30, 2022. With that, I turn the call back to David. Thank you, Nick. As I noted at the opening, our top line performance was modest. Activating go-to-market channel partnerships with large OEMs, distributor, and reseller partners does take some time. There is most certainly, in our view, a market for our product, and it has strong efficacy. We must now get our channels to a tipping point, and we do see reasons for optimism in sales across our product offering, sales across channel partners, and momentum across geographies. We're working hard with our partners to perfect sales strategies, which will benefit all parties. We hope investors can appreciate the uniqueness of our technology and market opportunity and demonstrate patience with Arqit as we strive to deliver success. I now hand the call back over to the operator for Q&A. Thank you. If you would like to ask a question, please press star one one on your telephone. If you would like to remove yourself from the queue, press star one one again and wait for your name to be announced before you proceed with your question. One moment while we prepare for the first question. Our first question today is coming from Scott Buck of H.C. Wainwright. Your line is open. Hi, good morning, everybody. Thank you for taking my question. David, I'm curious, how are you thinking about the anticipated ramp in revenue in 2024 as these relationships mature versus your current cash balance? I mean, do you have enough runway to get you at least meaningfully closer towards operating breakeven? Hello, Scott. Thank you for your question. We have confidence that the scale of our channel partnerships, and the increasing maturity of those partnerships does offer us the ability to get towards, cashflow breakeven, within a relatively modest time period. We're therefore reasonably confident that the amount of runway, that we currently have, gives us, a degree of comfort that we're satisfied with. Great. That's helpful. Then I wanted to ask, you have a good base of channel partners in place now. Are you still having meaningful discussions with other potential partners? Could we see, you know, announcements over the next few months on that end? Yes, we are. We are working hard with several very large technology companies who are similar OEMs with detailed software integration work in progress and go-to-market strategies under discussion. I'm hopeful that these partnerships will quite soon come to fruition and that they would be announceable in the short term. Great. That's helpful. And then last one for me. On the satellite business, are there other potential strategic opportunities besides just an outright sale that could help you, you know, at least partially monetize those assets? We are working, and have been for quite some time, with a number of potential partners who have expressed an interest in cooperating with us to monetize that satellite technology. It can't be certain that deals will come to fruition, but we are working very hard with a group of organizations that offer some potential for us to generate an elegant outcome for that project. Great. I appreciate the added color there, guys. Thanks for the time. Thank you, Scott. As a reminder, if you would like to ask a question, please press star one one on your telephone. At this time, I'm not seeing any further questions. I'll turn the call back over to David Williams for closing remarks. Please go ahead. Thank you, operator, and thank you everyone for joining the call. We look forward to speaking with our investors and analysts again following the close of our next fiscal half year results, and we are anticipating bringing forward some new investor events in the near term to share deeper information about our progress. Thank you all very much. Thank you, ladies and gentlemen. This concludes today's conference. Thank you for participating. You may now disconnect. Speakers, please stand by for your debrief.
