Risks Related to Our Business and Industry

We have limited operating history, have incurred operating losses for the years ended March 31, 2025 and 2024 and expect to incur significant losses for the foreseeable future. We may not generate sufficient revenue or become profitable or, if we achieve profitability, we may not be able to sustain it.

Biotechnology product development is a highly speculative undertaking and involves a substantial degree of risk. We are a clinical-stage biotechnology company with a limited operating history upon which you can evaluate our business and prospects. We commenced operations in 2013, and to date, we have focused primarily on organizing and staffing our company, business planning, raising capital, performing research and development activities, primarily the development of the ViraxImmune platform, establishing our intellectual property portfolio, and conducting clinical trials.

We have incurred operating losses since inception. If our products are not successfully commercialized, namely, ViraxImmune, we may not generate further revenue. Our net losses were $6,067,232, $6,739,120 and $5,457,763for the years ended March 31, 2025, 2024 and 2023, respectively. As of March 31, 2025, we had an accumulated deficit of $24,589,244. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. ViraxImmune products will require additional development time and resources before we will begin generating revenue from product sales. We expect to continue to incur losses for the foreseeable future, and we anticipate these losses will increase substantially as we conduct our ongoing research and development of our ViraxImmune products and seek to obtain product certification approvals in the territories we have identified, as well as hire additional personnel, obtain and protect our intellectual property and incur additional costs for commercialization or to expand our pipeline of product candidates.

To become and remain profitable, we must succeed in developing and eventually commercializing products that generate sufficient revenue. This will require us to be successful in a range of challenging activities, including completing preclinical studies and clinical trials of our product candidates, obtaining product certification approvals in the territories we have identified and manufacturing, marketing and selling any products for which we obtained product certification approvals. We may never succeed in these activities and, even if we do, may never generate revenues that are sufficient enough to achieve profitability. In addition, we have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biotechnology industry. Because of the numerous risks and uncertainties associated with biotechnology product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would depress the value of our company and could impair our ability to raise capital, expand our business, maintain our research and development efforts, diversify our product candidates or even continue our operations. A decline in the value of our company could also cause you to lose all or part of your investment.

We expect to make significant investments in our continued research and development of new products and services, which may not be successful.

We are seeking to build upon our existing research and development to develop a comprehensive set of T cell diagnostics and immune profiling solutions. Our strategic focus is the development and commercialization of immune profiling IVDs in indications associated with chronic inflammation and T cell exhaustion, such as post viral syndromes and other infectious diseases, chronic inflammation and immune-oncology.

Developing new products and services is a speculative and risky endeavor. Products or services that initially show promise may fail to achieve the desired results or may not achieve acceptable levels of analytical accuracy or clinical utility. We may need to alter our products in development and repeat clinical studies before we identify a potentially successful product or service. Product development is expensive, may take years to complete and can have uncertain outcomes. Failure can occur at any stage of the development. If, after development, a product or service appears successful, we may, depending on the nature of the product or service, still need to obtain regulatory clearances, authorizations or approvals before we can market it. The regulatory clearance, authorization or approval pathways are likely to involve significant time, as well as additional research, development and clinical study expenditures. The regulatory authorities may not clear, authorize or approve any future product or service we develop. Even if we develop a product or service that receives regulatory clearance, authorization or approval, we would need to commit substantial resources to commercialize, sell and market it before it could be profitable, and the product or service may never be commercially successful. Additionally, development of any product or service may be disrupted or made less viable by the development of competing products or services.

New potential products and services may fail at any stage of development or commercialization and if we determine that any of our current or future products or services are unlikely to succeed, we may abandon them without any return on our investment. If we are unsuccessful in developing additional products or services, our potential for growth may be impaired, and our business, financial condition and results of operations may be adversely affected.

If we are not successful in leveraging the ViraxImmune platform to discover, develop and commercialize additional products and services, our ability to expand our business and achieve our strategic objectives would be impaired.

A key element of our strategy is to leverage our ViraxImmune platform to address a wide range of research, diagnostic and health needs within indications associated with chronic inflammation and T cell exhaustion through our test kits and services. If we are unable to generate compelling evidence supporting our T cell test results, our platform may face a broader obstacle to using our diagnostics data for commercially viable products and services.

Identifying new products and services requires substantial technical, financial and human resources, whether or not any products or services are ultimately developed or commercialized. We may pursue what we believe is a promising opportunity to leverage our platform only to discover that certain of our risk or resource allocation decisions were incorrect or insufficient, or that individual products, services or our science in general has technology or biology risks that were previously unknown or underappreciated. Our strategy of pursuing the value of our diagnostics platform over a long time horizon and developing relevant technological products with synergy may not be effective. In the event material decisions in any of these areas turn out to be incorrect or sub-optimal, we may experience a material adverse impact on our business and ability to fund our operations and we may never realize what we believe is the potential of our in-vitro diagnostics platform.

Our efforts to develop a T cell In-Vitro Diagnostic Test may not be successful, and it may not yield the insights we expect at all or on a timetable that allows us to develop or commercialize any new diagnostic products.

We are currently developing a comprehensive set of T cell diagnostics and immune profiling solutions. Our strategic focus is the development and commercialization of immune profiling IVDs in indications associated with chronic inflammation and T cell exhaustion, such as post viral syndromes and other infectious diseases, chronic inflammation and immune-oncology.

ViraxImmune may not yield clinically actionable insights on a timetable that is commercially viable, or at all. ViraxImmune will initially be focusing in diseases associated with post viral syndromes including but not limited to SARS-CoV-2, Human Papillomavirus (better known as HPV), Malaria, Hepatitis B, and Herpes (better known as HSV-1). If our efforts do not accelerate the pace at which we can validate our diagnostic method, the timetable for our business model may not be commercially viable. Even if we can accelerate this timeline, our products and services derived from our novel technologies may have product or service level errors. If we are unable to make meaningful progress in our technology and successfully use it to develop and commercialize new diagnostic products or services, our business and results of operations will suffer.

If we are not successful in obtaining regulatory approvals for our ViraxImmune products, we may not be able to commercialize our products in the expected timeframe or at all, and our ability to expand our business and achieve our strategic objectives would be impaired.

Currently, we are developing a comprehensive set of T cell diagnostics and immune profiling solutions. Our strategic focus is the development and commercialization of immune profiling IVDs in indications associated with chronic inflammation and T cell exhaustion, such as post viral syndromes and other infectious diseases, chronic inflammation and immune-oncology. For example, in the United States, the FDA regulates the sale or distribution of medical devices, including but not limited to, IVD test kits. IVD products are subject to regulation by the FDA as medical devices to the extent that they are intended for use in the diagnosis, treatment, mitigation or prevention of disease or other conditions. They are subject to premarket review and post market controls which will differ depending on how the FDA classifies a specific IVD.

The information that must be submitted to the FDA in order to obtain clearance or approval to market a new medical device varies depending on how the medical device is classified by the FDA. Medical devices are classified into one of three classes depending on the controls deemed by the FDA to be necessary to reasonably ensure their safety and effectiveness. Class I devices are subject to general controls, including labeling requirements, and adherence to the FDA’s quality system regulations, or QSRs, which are device-specific current good manufacturing practices. Class II devices are subject to premarket notification, QSRs, general controls and sometimes special controls, including performance standards and post-market surveillance. Class III devices are subject to most of the previously identified requirements as well as to pre-market approval. Class I devices are exempt from premarket review; most Class II devices require 510(k) clearance, and all Class III devices must receive premarket approval before they can be sold in the United States.

A 510(k) premarket notification requires the sponsor to demonstrate that a medical device is substantially equivalent to another marketed device, termed a “predicate device,” that is legally marketed in the United States and for which a premarket approval was not required. A device is substantially equivalent to a predicate device if it has the same intended use and technological characteristics as the predicate; or has the same intended use but different technological characteristics, where the information submitted to the FDA does not raise new questions of safety and effectiveness and demonstrates that the device is at least as safe and effective as the legally marketed device.

A Premarket Approval process is more complex, costly and time consuming than the 510(k) process. A PMA must be supported by more detailed and comprehensive scientific evidence, including clinical data, to demonstrate the safety and efficacy of the medical device for its intended purpose. If the device is determined to present a “significant risk,” the sponsor may not begin a clinical trial until it submits an investigational device exemption (IDE) to the FDA and obtains approval to begin the trial.

Should we fail to obtain the necessary FDA or the relevant regulatory authority’s approval, for example, to demonstrate to the FDA or the relevant regulatory authority’s satisfaction that our T cell IVD/Immune response Test kits are safe and effective, we may not be able to commercialize our ViraxImmune product and/or platform in the expected timeframe or at all, and our ability to expand our business and achieve our strategic objectives would be impaired.

We will face significant challenges in successfully commercializing our products, particularly in new markets.

We intend to grow our own sales and marketing capabilities and promote our product candidates if and when regulatory approval has been obtained in the United Kingdom, European Union and North America, and to expand to other markets as well. In order to successfully commercialize our products in these new markets, we require appropriate infrastructure such as information technology, enterprise resource planning and forecasting. We may fail to launch our products effectively or to market our products effectively. Recruiting and training a sales force is expensive and costs of creating an independent sales and marketing organization and of marketing and promotion could be above what we anticipate. In addition, recruiting and training a sales force is time consuming and could delay any product launch. In the event that any such launch is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel.

If we enter into arrangements with third parties to perform sales and marketing services, our product revenues or the profitability of these product revenues to us could be lower than if we were to market and sell any products that we develop ourselves. Such collaborative arrangements may place the commercialization of our products outside of our control and would make us subject to a number of risks, including that we may not be able to control the amount or timing of resources that our collaborative partner devotes to our products or our collaborator’s willingness or ability to complete its obligations, and our obligations under our arrangements may be adversely affected by business combinations or significant changes in our collaborator’s business strategy. In addition, we may not be successful in entering into arrangements with third parties to sell and market our products or may be unable to do so on terms that are favorable to us. Acceptable third parties may fail to devote the necessary resources and attention to sell and market our products effectively.

If we do not establish sales and marketing capabilities in new markets successfully in our targeted expansion regions or countries, either on our own or in collaboration with third parties, we may not be successful in commercializing our products, which in turn would have a material adverse effect on our business, financial condition and results of operations.

Our business, financial condition and results of operations will depend on the market acceptance and increased demand for our products by Contract Research Organizations, hospitals, governments and public health departments, as well as physicians and

others in the medical community, and the growing proportion of the population who are interested in taking personal charge over their health and well-being.

Our future success depends on our products gaining sufficient market acceptance by hospitals, public health departments and consumer groups interested in their health and well-being. If our products do not achieve an adequate level of acceptance by such customer groups, we may not generate enough revenue to become profitable. For example, the degree of market acceptance of our T cell in-vitro diagnostics product will depend on a number of factors, including:

Our efforts to educate physicians and other members of the medical community on the benefits of our products may require significant resources and may never be successful. Such efforts to educate the marketplace may require more resources than are required by conventional technologies marketed by our competitors. In particular, continuing to gain market acceptance for our products in nascent markets could be challenging. In certain markets, our potential for future growth is difficult to forecast. If we were to incorrectly forecast our ability to penetrate these markets, expenditures that we make may not result in the benefits that we expect, which could harm our results of operations. Additionally, if we lose any of our customers due to significant delays in our ability to obtain re-registration of our T cell IVD/Immune response Test in our initial target markets, our results of operations could be materially and adversely affected.

In the event that our products are the subject of guidelines, clinical studies or scientific publications that are unhelpful or damaging, or otherwise call into question the benefits of our products, we may have difficulty in convincing prospective customers to adopt our test. Moreover, the perception by the investment community or shareholders that recommendations, guidelines or studies will result in decreased use of our products could adversely affect the prevailing market price for our ordinary shares. Similar challenges apply to all of the products in our pipeline.

The success of some of our products partially depends on the continued demand for diagnostic products linked to chronic conditions where immune dysfunction and chronic inflammation are central to the condition

There is every indication that the incidence of chronic infection and chronic inflammatory disorders linked to symptoms of chronic fatigue and cognitive impairment are increasing. As a result we believe that there will be rising healthcare expenditures, large patient population, and government support for research and development to deal with this growing problem. However, our assessments of the market potential for these types of diagnostic products my prove innacurate.

The success of our proprietary technology T cell testing requires us to proceed through clinical and validation studies successfully, which is not guaranteed.

In order for our proprietary technology T cell IVD/Immune response Test to be successful, we are required to successfully proceed through further clinical and validation studies, which is not guaranteed. Clinical testing or validation is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time and may adversely affect our operations and finances should there be a prolonged process of clinical and validation studies.

New market opportunities may not develop as quickly as we expect, limiting our ability to market and sell our products successfully.

We intend to take steps to continue to increase the presence of our products in markets both in the target markets and in the wider international market including the United Kingdom, European Union, United States and Canada. We intend to grow our sales force globally and establish distributor relationships to better access international markets. We believe these opportunities will take substantial time to develop or mature, however, and we cannot be certain that these market opportunities will develop as we expect. The future growth and success of our products in these markets depends on many factors beyond our control, including recognition and acceptance by the scientific community in that market and the prevalence and costs of competing methods of viral screening. If the markets for our products do not develop as we expect, our business may be adversely affected.

Our efforts to discover and develop products and services related to the ViraxImmune products may not be successful from either a platform extension or commercialization perspective.

We are in the process of developing a comprehensive set of T-cell diagnostics and immune profiling solutions. The platform's capabilities will initially focus on measuring chronic inflammation associated with T-cell exhaustion in areas such as Long COVID effects, Chimeric Antigen Receptor T-cell (CAR-T) therapies, Myloid, Encephalomyelitis (ME) and post viral syndromes. We are still in the process of conducting further tests and we have not submitted any clinical performance studies to any regulatory agency for approval. While we believe quantifying virus-specific T cells may provide important research and diagnostic advantages because T cells persist in the immune system later than antibodies, the data upon which such belief is based is limited and our analyses are preliminary. As we continue to collect and analyze additional data, we may find that our initial hypotheses are not applicable to some major viral diseases, or are not supported by a larger data set or further analysis. If our beliefs regarding the effectiveness of T cells in-vitro diagnostics tests are incorrect, that could have a material adverse effect on the market for T cells in-vitro diagnostics tests, our revenue expectations, reputation, financial condition, and our stock price, which would be adversely impacted.

Our efforts to further develop and commercialize T cell diagnostics tests involve a high degree of risk, and our efforts may fail for many reasons, including:

Additionally, there can be no assurances as to the commercial success of T cell in-vitro diagnostics tests for major viral disease. Our investments in the discovery and development of products and services related to major viral disease may not be accretive to our future financial results and if we determine that any product or service is unlikely to succeed, we may abandon them without any return on our investment.

We may be liable for improper collection, use or appropriation of personal information provided by our customers.

We collect certain personal data from our customers in target markets in connection with our business and operations, and we may expand our collection of data into areas including genetic data. Our collection of customer data is subject to various regulatory requirements relating to the security and privacy of data in various jurisdictions. Regulatory requirements regarding the protection of data are constantly evolving and can be subject to different interpretations or significant change, making the extent of our responsibilities in that regard uncertain.

In Europe, Directive 95/46/EC of the European Parliament and of the Council of October 24, 1995 on the protection of individuals with regard to the processing of personal data and on the free movement of such data, or the Directive, and Directive 2002/58/EC of the European Parliament and of the Council of July 12, 2002 concerning the processing of personal data and the protection of privacy in the electronic communications sector (as amended by Directive 2009/136/EC), or the e-Privacy-Directive, have required the European Union, or EU member states, to implement data protection laws to meet strict privacy requirements. Violations of these requirements can result in administrative measures, including fines, or criminal sanctions. The e-Privacy Directive will likely be replaced in time by a new e-Privacy Regulation which may impose additional obligations and risk for our business.

Beginning on May 25, 2018, the Directive was replaced by Regulation (EU) 2016/679 of the European Parliament and of the Council of April 27, 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data, or the GDPR. The GDPR imposes a broad range of strict requirements on companies subject to the GDPR, such as us, including requirements relating to having legal bases for processing personal information relating to identifiable individuals and transferring such information outside the European Economic Area, or the EEA, including to the United States, providing details to those individuals regarding the processing of their personal information, keeping personal information secure, having data processing agreements with third parties who process personal information, responding to individuals’ requests to exercise their rights in respect of their personal information, reporting security breaches involving personal data to the competent national data protection authority and affected individuals, appointing data protection officers, conducting data protection impact assessments, and record-keeping. The GDPR substantially increases the penalties to which we could be subject in the event of any non-compliance, including fines of up to 10,000,000 Euros or up to 2% of our total worldwide annual turnover for certain comparatively minor offenses, or up to 20,000,000 Euros or up to 4% of our total worldwide annual turnover for more serious offenses. We face uncertainty as to the exact interpretation of the

requirements under the GDPR, and we may be unsuccessful in implementing all measures required by data protection authorities or courts in interpretation of the GDPR.

In particular, national laws of member states of the EU are in the process of being adapted to the requirements under the GDPR, thereby implementing national laws which may partially deviate from the GDPR and impose different obligations from country to country, so that we do not expect to operate in a uniform legal landscape in the EU. In the future, should we collect any genetic data in connection with our business and operations, our operations may also be subject to the GDPR, which specifically allows national laws to impose additional and more specific requirements or restrictions, and European laws have historically differed quite substantially in this field, leading to additional uncertainty.

We expect that we will continue to face uncertainty as to whether our efforts to comply with our obligations under European privacy laws will be sufficient. If we are investigated by a European data protection authority, we may face fines and other penalties. Any such investigation or charges by European data protection authorities could have a negative effect on our existing business and on our ability to attract and retain new clients or pharmaceutical partners. We may also experience hesitancy, reluctance, or refusal by European or multi-national clients or pharmaceutical partners to continue to use our products and solutions due to the potential risk exposure as a result of the current (and, in particular, future) data protection obligations imposed on them by certain data protection authorities in interpretation of current law, including the GDPR. Such clients or pharmaceutical partners may also view any alternative approaches to compliance as being too costly, too burdensome, too legally uncertain, or otherwise objectionable and therefore decide not to do business with us. Any of the foregoing could materially harm our business, prospects, financial condition and results of operations.

In Singapore, under the Personal Data Protection Act 2012 (the “PDPA”), we are required to, among others, notify individuals of the purposes for the collection, use or disclosure of their personal data prior to such collection, and to also disclose and obtain the consent of individuals during the collection, use or disclosure of their personal data.

A part of our operations is also carried out in China and a portion of the data and personal information we collected will need to be stored in China where relevant to ensure compliance with the Peoples Republic of China ("PRC") laws. We do not hold personal information of more than one million users and we believe that the Company’s initial public offering (“IPO”) of ordinary shares in July 2022 was not subject to PRC cybersecurity review. In addition, as of the date of this report, we have not received any notice of and are not currently subject to any proceedings initiated by the CAC or any other PRC regulatory authority. In addition, we may be subject to heightened regulatory scrutiny from PRC governmental authorities in the future. As there remains significant uncertainty in the interpretation and enforcement of the Data Security Law and the PRC Personal Information Protection Law (the "PIPL"), we cannot assure you that we will comply with such regulations in all respects. Any non-compliance with these laws and regulations may subject us to fines, orders to rectify or terminate any actions that are deemed illegal by regulatory authorities, other penalties, including but not limited to reputational damage or legal proceedings against us, which may affect our business, financial condition or results of operations.

The in-vitro diagnostics industry is subject to rapid change, which could make our diagnostics platform and related products and services that we develop obsolete.

Our industry is characterized by rapid changes, including technological and scientific breakthroughs, frequent new product and service introductions and enhancements and evolving industry standards, all of which could make our current and future products and services obsolete. Our future success will depend on our ability to keep pace with the evolving needs of our customers on a timely and cost-effective basis and to pursue new market opportunities that develop as a result of scientific and technological advances. In recent years, there have been numerous advances in technologies relating to the diagnosis and treatment of viral diseases. There have also been advances in technologies used to computationally analyze very large amounts of biologic information. If we do not update our products and services to reflect new scientific knowledge about diagnostics technology, software development, our products and services could become obsolete and any sales of our current products and services and any future products and services we develop based on our diagnostics platform could decline or fail to grow as expected.

Our business could suffer if we lose the services of, or are unable to attract and retain, key members of our senior management, key advisors or other personnel.

We are dependent upon the continued services of key members of our senior management, including James Foster and Nigel McCracken. The loss of any one of these individuals, without adequate time to find a suitable replacement, could disrupt our operations or our strategic plans. Additionally, our future success will depend on, among other things, our ability to continue to hire and retain the necessary qualified scientific, technical, sales, marketing and managerial personnel, for whom we compete with numerous other companies, academic institutions and organizations. The loss of members of our management team, key advisors or personnel, or our inability to attract or retain other qualified personnel or advisors, could have a material adverse effect on our business, results of operations and financial condition. Although all members of our senior management team have entered into agreements that restrict their ability to compete with us for a period of time after the end of their employment, we may be unable to enforce such restrictive covenants at all or for a sufficient duration of time to prevent members of our management team from competing against us.

We depend on our information technology systems and any failure of these systems could harm our business.

We depend on information technology and telecommunications systems, including third-party cloud computing infrastructure and operating systems, for significant elements of our operations, including our products research and development and e-commerce platform development.

We use complex software processes to manage and test samples and evaluate the resulting data. These are subject to initial design or ongoing modifications which may result in unanticipated issues that could cause variability in patient results, leading to service disruptions or errors, and resulting in liability.

We have installed, and expect to expand, a number of enterprise software systems that affect a broad range of business processes and functional areas, including systems handling human resources, financial controls and reporting, contract management, regulatory compliance and other infrastructure operations. In addition to these business systems, we have installed, and intend to extend, the capabilities of both our preventative and detective cybersecurity controls by augmenting the monitoring and alerting functions, the network design and the automatic countermeasure operations of our technical systems. These information technology and telecommunications systems will support a variety of functions, including laboratory operations, test validation, sample tracking, quality control, customer service support, billing and reimbursement, research and development activities, scientific and medical curation and general administrative activities. In addition, our third-party billing and collections provider depends upon technology and telecommunications systems provided by outside vendors.

Information technology and telecommunications systems are vulnerable to damage from a variety of sources, including telecommunications or network failures, malicious human acts (such as ransomware) and natural disasters. Moreover, despite network security and back-up measures, some of our servers are potentially vulnerable to physical or electronic break-ins, computer viruses and similar disruptive problems. Despite the precautionary measures we have taken to prevent unanticipated problems that could affect our information technology and telecommunications systems, failures or significant downtime of these systems or those used by our partners or subcontractors could prevent us from conducting our diagnostic products development, completing the tests on our customer samples, preparing and providing reports to researchers, clinicians and our partners, billing and payments, handling enquiries, conducting research and development activities and managing the administrative aspects of our business. Any disruption or loss of information technology or telecommunications systems on which critical aspects of our operations depend could have an adverse effect on our business and our reputation, and we may be unable to regain or repair our reputation in the future.

We face risks related to natural disasters, health epidemics and other outbreaks which could significantly disrupt our operations.

In general, our business could be adversely affected by the effects of epidemics, including, but not limited to, SARS-CoV-2, avian influenza, severe acute respiratory syndrome (SARS), the influenza A virus, Ebola virus, severe weather conditions such as a snowstorm, flood or hazardous air pollution, or other outbreaks. In response to an epidemic, severe weather conditions, or other outbreaks, government and other organizations may adopt regulations and policies that could lead to severe disruption to our daily operations, including temporary closure of our offices and other facilities. These severe conditions may cause us and/or our partners to make internal adjustments, including but not limited to, temporarily closing down business, limiting business hours, and setting restrictions on travel and/or visits with clients and partners for a prolonged period of time. Various impacts arising from severe conditions may cause business disruption, resulting in material, adverse impact to our financial condition and results of operations.

Risks Related to Intellectual Property

We Do Not Own Any Patents, Which May Limit Our Ability to Protect Our Proprietary Technology and Could Adversely Affect Our Competitive Position and Business.

Our business relies on proprietary technology, software, and processes that we believe provide us with a competitive advantage in the biotechnology and diagnostics industries. However, we do not currently own any patents to protect our proprietary technology. In the technology industry, patents are often used to safeguard intellectual property, prevent competitors from replicating key innovations, and enhance a company’s market position. Our lack of patent protection may expose us to significant risks, including:

We may in the future seek to obtain patents to protect our innovations, but there can be no assurance that we will be able to secure patents, that any patents issued will adequately protect our technology, or that pursuing patents will be cost-effective. The process of obtaining patents is expensive, time-consuming, and uncertain, and any failure to secure patent protection could limit our ability to maintain a competitive edge. Additionally, competitors with established patent portfolios may assert claims against us, alleging infringement, which could result in costly litigation, licensing fees, or the need to redesign our products or services. Any of these outcomes could materially adversely affect our business, financial condition, results of operations, and stock price.

If we are not able to adequately protect our proprietary intellectual property and information, and protect against third party claims that we are infringing on their intellectual property rights, our results of operations could be adversely affected.

The value of our business depends in part on our ability to protect our intellectual property and information, including our copyrights, trademarks, trade secrets, and rights under agreements with third parties, in the United Kingdom and around the world, as well as our customers, employees, and customer data. Third parties may try to challenge our ownership of our intellectual property globally. In addition, intellectual property rights and protections in the United Kingdom may be insufficient to protect material intellectual property rights globally and the United Kingdom. Further, our business is subject to the risk of third parties counterfeiting our products or infringing on our intellectual property rights. The steps we have taken may not prevent unauthorized use of our intellectual property. We may need to resort to litigation to protect our intellectual property rights, which could result in substantial costs and diversion of resources. If we fail to protect our proprietary intellectual property and information, including with respect to any successful challenge to our ownership of intellectual property or material infringements of our intellectual property, this failure could have a significant adverse effect on our business, financial condition, and results of operations.

If we are unable to adequately protect our intellectual property rights, or if we are accused of infringing on the intellectual property rights of others, our competitive position could be harmed or we could be required to incur significant expenses to enforce or defend our rights.

Our commercial success will depend in part on our success in obtaining and maintaining copyrights, trademarks, trade secrets and other intellectual property rights in Europe and elsewhere and protecting our proprietary technology. If we do not adequately protect our intellectual property and proprietary technology, competitors may be able to use our technologies or the goodwill we have acquired in the marketplace and erode or negate any competitive advantage we may have, which could harm our business and ability to achieve profitability.

Other parties may have developed technologies that may be related or competitive to our system, may have filed or may file patent applications and may have received or may receive patents that overlap or conflict with any patent applications we may file in future, either by claiming the same methods or devices or by claiming subject matter that could dominate our patent position. Any patent position may involve complex legal and factual questions, and, therefore, the scope, validity and enforceability of any patent claims that we may obtain cannot be predicted with certainty. Patents, if issued, may be challenged, deemed unenforceable, invalidated or circumvented. Proceedings challenging any patents we may obtain could result in either loss of the patent or denial of the patent application or loss or reduction in the scope of one or more of the claims of the patent or patent application. In addition, such proceedings may be costly. Thus, any patents that we may obtain may not provide any protection against competitors.

Competitors could purchase our products and attempt to replicate some or all of the competitive advantages we derive from our development efforts, willfully infringe our intellectual property rights, or develop and obtain patent protection for more effective technologies, designs or methods. We may be unable to prevent the unauthorized disclosure or use of our technical knowledge or trade secrets by consultants, suppliers, vendors, former employees and current employees.

The degree of future protection for our proprietary rights is uncertain, and we cannot ensure that:

We rely, in part, upon unpatented trade secrets, unpatented know-how and continuing technological innovation to develop and maintain our competitive position. Further, our trade secrets could otherwise become known or be independently discovered by our competitors.

Any inability of us to protect our competitive advantage with regard to any of our product candidates may prevent us from successfully monetizing such product candidate and this could materially adversely affect our business, prospects, financial condition and results of operations.

Litigation or other proceedings or third-party claims of intellectual property infringement could require us to spend significant time and money and could prevent us from selling our products or affect our stock price.

Our commercial success will depend in part on not infringing the patents or copyrights, or otherwise violating the other proprietary rights of others. Significant litigation regarding patent rights and copyright rights occur in our industry. Our competitors around the globe, many of which have substantially greater resources and have made substantial investments in patent portfolios and competing technologies, may have applied for or obtained or may in the future apply for and obtain, patents that will prevent, limit or otherwise interfere with our ability to make, use and sell our products. In addition, patent applications in Europe and elsewhere can be pending for many years before issuance, or unintentionally abandoned patents or applications can be revived, so there may be applications of others now pending or recently revived patents of which we are unaware. These applications may later result in issued patents, or the revival of previously abandoned patents, that will prevent, limit or otherwise interfere with our ability to make, use or sell our products. Third parties may, in the future, assert claims that we are employing their proprietary technology without authorization. As we continue to commercialize our products in their current or updated forms, launch new products and enter new markets, we expect competitors may claim that one or more of our products infringe their intellectual property rights as part of business strategies designed to impede our successful commercialization and entry into new markets. The large number of patents, the rapid rate of new patent applications and issuances, the complexities of the technology involved, and the uncertainty of litigation may increase the risk of business resources and management’s attention being diverted to patent litigation. We have, and we may in the future, receive letters or other threats or claims from third parties inviting us to take licenses under, or alleging that we infringe, their patents.

Moreover, we may become party to future adversarial proceedings regarding the patents of third parties. The legal threshold for initiating litigation or contested proceedings may be low, so that even lawsuits or proceedings with a low probability of success might be initiated. Litigation and contested proceedings can also be expensive and time-consuming, and our adversaries in these proceedings may have the ability to dedicate substantially greater resources to prosecuting these legal actions than we can. We may also occasionally use these proceedings to challenge the patent rights of others. We cannot be certain that any particular challenge will be successful in limiting or eliminating the challenged patent rights of the third party.

Any lawsuits resulting from such allegations could subject us to significant liability for damages and invalidate our proprietary rights. Any potential intellectual property litigation also could force us to do one or more of the following:

Any litigation or claim against us, even those without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention of management from our core business and harm our reputation. If we are found to infringe the intellectual property rights of third parties, we could be required to pay substantial damages (which may be increased up to three times of awarded damages) and/or substantial royalties and could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. Any such license may not be available on reasonable terms, if at all, and there can be no assurance that we would be able to redesign our products in a way that would not infringe the intellectual property rights of others. We could encounter delays in product introductions while we attempt to develop alternative methods or products. If we fail to obtain any required licenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable to commercialize one or more of our products.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position could be harmed.

We rely on copyright, trade secret and trademark protection as well as confidentiality agreements with our employees, consultants and third parties, and we may in the future rely on additional intellectual property protection, to protect our confidential and proprietary information. In addition to contractual measures, we try to protect the confidential nature of our proprietary information using commonly accepted physical and technological security measures. Such measures may not, for example, in the case of misappropriation of a trade secret by an employee or third party with authorized access, provide adequate protection for our proprietary information. Our security measures may not prevent an employee or consultant from misappropriating our trade secrets and providing them to a competitor, and recourse we take against such misconduct may not provide an adequate remedy to protect our interests fully. Unauthorized parties may also attempt to copy or reverse engineer certain aspects of our products that we consider proprietary. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can be difficult, expensive and time-consuming, and the outcome is unpredictable. Even though we use commonly accepted security measures, trade secret violations are often a matter of state law, and the criteria for protection of trade secrets can vary among different jurisdictions. In addition, trade secrets may be independently developed by others in a manner that could prevent legal recourse by us. If any of our confidential or proprietary information, such as our trade secrets, were to be disclosed or misappropriated, or if any such information was independently developed by a competitor, our business and competitive position could be harmed.

Third parties may assert ownership or commercial rights to inventions we develop, which could have a material adverse effect on our business.

Third parties may in the future make claims challenging the inventorship or ownership of our intellectual property. Any infringement claims or lawsuits, even if not meritorious, could be expensive and time consuming to defend, divert management’s attention and resources, require us to redesign our products and services, if feasible, require us to pay royalties or enter into licensing agreements in order to obtain the right to use necessary technologies, and/or may materially disrupt the conduct of our business.

In addition, we may face claims by third parties that our agreements with employees, contractors or third parties obligating them to assign intellectual property to us are ineffective or in conflict with prior or competing contractual obligations of assignment, which could result in ownership disputes regarding intellectual property we have developed or will develop and interfere with our ability to capture the commercial value of such intellectual property. Litigation may be necessary to resolve an ownership dispute, and if we are not successful, we may be precluded from using certain intellectual property or may lose our exclusive rights in that intellectual property. Either outcome could harm our business and competitive position.

Third parties may assert that our employees or contractors have wrongfully used or disclosed confidential information or misappropriated trade secrets, which could result in litigation.

We may employ individuals who previously worked with other companies, including our competitors or potential competitors. Although we try to ensure that our employees and contractors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or our employees or contractors have inadvertently or otherwise used or disclosed intellectual property or personal data, including trade secrets or other proprietary information, of a former employer or other third party. Litigation may be necessary to defend against these claims. If we fail in defending any such claims or settling those claims, in addition to paying monetary damages or a settlement payment, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees.

Risks Related to Regulatory and Other Legal Issues.

The regulatory environment for IVD could change, resulting in a new procedure for achieving approvals for various global marketplaces which might adversely affect Virax’s ability to enter various markets.

Changes in the current regulatory framework for IVD can impose additional regulatory burdens on us. In addition, there is currently an on-going review as to acceptance of EU MDR and EU IVDR CE certificates renewed which we cannot be certain of in future developments. As the regulatory framework evolves in the targeted jurisdictions for our current in-development T Cell IVD/Immune response Test under the ViraxImmune brand, we may incur substantial costs to ensure compliance with new or amended laws and regulations. Failure to comply with any of these laws and regulations could result in enforcement actions against us, damage to our reputation, render us unable to commercialize our ViraxImmune product and/or platform in the expected timeframe or at all, and our ability to expand our business and achieve our strategic objectives would be impaired, any of which could have a material adverse effect on our business.

If we fail to comply with the extensive regulations of domestic and international regulatory authorities, sales of our products in new markets and the development and commercialization of any new product candidates could be delayed or prevented.

Our existing tests, as well as new tests, will be subject to extensive government regulations related to development, testing, manufacturing and commercialization in Europe, the United States and other countries before we can sell in these markets. The process of obtaining and complying with the relevant governmental regulatory approvals and regulations is costly, time consuming, uncertain and subject to unanticipated delays. Despite the time and expense exerted, regulatory approval is never guaranteed. We may not be able to obtain the required regulatory approval and market any further products we may develop during the time we anticipate, or at all. We also are subject to the following risks and obligations, among others:

In addition, some international jurisdictions, require periodic re-registration. Even if we obtain initial registrations from regulatory bodies, we may lose registration after a periodic review. It is possible that governmental authorities will conclude that our business practices do not comply with current or future statutes and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion of our products from government funded healthcare programs, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, reputational harm and the curtailment or restructuring of our operations. Defending against any such actions can be costly and time-consuming and may require significant financial resources.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. For example, the provision of benefits or advantages to physicians to induce or encourage the prescription, recommendation, endorsement, purchase, supply, order or use of medicinal products is generally not permitted in the countries that form part of the European Union. Some European Union Member States have enacted laws explicitly prohibiting the provision of these types of benefits and advantages to induce or reward improper performance generally, and the United Kingdom has enacted such laws through the Bribery Act 2010. Infringements of these laws can result in substantial fines and imprisonment. EU Directive 2001/83/EC, which is the EU Directive governing medicinal products for human use, further provides that, where medicinal products are being promoted to persons qualified to prescribe or supply them, no gifts, pecuniary advantages or benefits in kind may be supplied, offered or promised to such persons unless they are inexpensive and relevant to the practice of medicine or pharmacy. This provision has been transposed into the Human Medicines Regulations 2012 and so remains applicable in the UK despite its departure from the EU. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business.

If we or our suppliers fail to comply with ongoing regulatory requirements, or if we experience unanticipated problems with our products, these products could be subject to restrictions or withdrawal from the market.

Any product for which we obtain marketing approval in the United Kingdom, United States or in international jurisdictions, along with the manufacturing processes, post-approval clinical data and promotional activities for such product, will be subject to continual review and periodic inspections by the relevant regulatory bodies. Furthermore, our suppliers may be subject to similar regulatory oversight, and may not currently be or may not continue to be in compliance with applicable regulatory requirements. Failure by us or one of our suppliers to comply with statutes and regulations administered by the relevant regulatory bodies, or failure to take adequate action in response to any observations, could result in, among other things, any of the following enforcement actions:

If any of these actions were to occur, it could harm our reputation and could cause our product sales and profitability to suffer.

Any regulatory approval of a product may also be subject to limitations on the indicated uses for which the product may be marketed. If the FDA or another regulatory body determines that our promotional materials, training or other activities constitute promotion of an unapproved use, it could request that we cease or modify our training or promotional materials or subject us to regulatory enforcement actions. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our training or promotional materials to constitute promotion of an unapproved use, which could result in significant fines or penalties under applicable statutory authorities, such as laws prohibiting false claims for reimbursement. The following are significant regulations that are currently applicable and could also be applicable to our products due to our target markets:

European Union Regulations

The European In-Vitro Diagnostic Regulation (IVDR 2017/746) (“IVDR”) introduced a new risk-based classification system and requirements for conformity assessments. Products self-certified placed on the market before May 22, 2022 under the European In-Vitro Diagnostic Devices Directive (IVDD 98/79/EC) (“IVDD”) may remain on the market until the following dates, afterward they will require the involvement of a Notified Body under the IVDR for the first time:

IVD manufacturers may only rely on the transitional provisions above provided that: (i) the devices continue to comply with applicable requirements imposed by the IVDD; (ii) they respect the IVDR requirements relating to post-market surveillance, market surveillance, vigilance, registration of economic operators and devices from May 26, 2022 in place of the corresponding requirements in the IVDD; and (iii) no significant changes are made in the design and intended purpose of the devices during the transitional period.

CE Marking is required for all IVD devices sold in Europe. CE Marking indicates that an IVD device complies with the IVDR and that the device may be legally commercialized in the EU.

It should be appreciated that there is a severe shortage of capacity of Notified Bodies to assess all IVDs that will require Notified Body certification under the IVDR, and that it is widely recognized that applications for assessment by the Notified Bodies may be subject to significant delays.

United Kingdom Regulations

The UK’s withdrawal from the EU will have major ramifications for IVD manufacturers that will, among other things have to follow new procedures that will apply in the UK including appointment of a UK Responsible Person rather than relying on European Authorized Representatives to manage their compliance efforts in the UK.

IVDs compliant with the EU in vitro diagnostic medical devices regulation (EU IVDD) can be placed on the Great Britain market up until the 30 June 2030. We intend to use the recognized CE marks that we will apply with the European Union for our medical device product, namely our current in development T cell IVD/Immune response Test under the ViraxImmune brand. After which, we will apply with the UK Medicine and Healthcare Products Regulatory Agency for a UK Conformity Assessed mark.

U.S. Regulations

We consider the United States as a target market with significant potential. As such, United States regulations will be applicable to our products once we market our products in the United States. In the United States, the FDA regulates the sale or distribution of medical devices, including but not limited to, IVD test kits. IVD products are subject to regulation by the FDA as medical devices to the extent

that they are intended for use in the diagnosis, treatment, mitigation or prevention of disease or other conditions. They are subject to premarket review and post market controls which will differ depending on how the FDA classifies a specific IVD.

The information that must be submitted to the FDA in order to obtain clearance or approval to market a new medical device varies depending on how the medical device is classified by the FDA. Medical devices are classified into one of three risk-based classes depending on the controls deemed by the FDA to be necessary to reasonably ensure their safety and effectiveness. Class I devices are considered the lowest risk and are subject to general controls, including labeling requirements, and adherence to the FDA’s quality system regulations, or QSRs, which are device-specific current good manufacturing practices. Class II (intermediate risk) devices may be subject to premarket notification, or may be 510(k)-exempt, and are generally subject to QSRs, general controls and sometimes special controls, including performance standards and post-market surveillance. Class III (highest risk) devices are subject to most of the previously identified requirements as well as to pre-market approval. Class I devices are exempt from premarket review; most Class II devices require 510(k) clearance, and all Class III devices must receive premarket approval before they can be sold in the United States. The payment of a user fee, which is typically adjusted annually, to the FDA is usually required when a 510(k) notice or premarket approval application is submitted.

510(k) Premarket Notification.

A 510(k) premarket notification requires the sponsor to demonstrate that a medical device is substantially equivalent to another marketed device, termed a “predicate device,” that is legally marketed in the United States and for which a premarket approval was not required. A device is substantially equivalent to a predicate device if it has the same intended use and technological characteristics as the predicate; or has the same intended use but different technological characteristics, where the information submitted to the FDA does not raise new questions of safety and effectiveness and demonstrates that the device is at least as safe and effective as the legally marketed device.

If the FDA believes that the device is not substantially equivalent to a predicate device, it will issue a “Not Substantially Equivalent” (NSE) determination and designate the device as a Class III device, which will require the submission and approval of a PMA before the new device may be marketed. A person who receives an NSE determination in response to a 510(k) submission may, within 30 days of receipt of the NSE determination, submit a de novo request for the FDA to make a risk-based evaluation for classification of the device into Class I or II. Devices that are classified through the de novo process may be marketed and used as predicates for future 510(k) submissions. The FDA continues to reevaluate the 510(k) pathway and process and the de novo process, and has taken what it describes as a risk-based approach to develop innovative regulatory policy to propose a more “contemporary” approach. In October 2017, the FDA published a final guidance entitled, “De Novo Classification Process (Evaluation of Automatic Class III Designation),” and in December 2018, the FDA published a proposed rule which if finalized is intended to provide structure, clarity and transparency on the de novo classification process. In January 2021, it also published a final guidance entitled “Requests for Feedback and Meetings for Medical Device Submissions: The Q-Submission Program.”

Premarket Approval. The PMA process is more complex, costly and time consuming than the 510(k) process. A PMA must be supported by more detailed and comprehensive scientific evidence, including clinical data, to demonstrate the safety and efficacy of the medical device for its intended purpose. If the device is determined to present a “significant risk,” the sponsor may not begin a clinical trial until it submits an investigational device exemption (IDE) to the FDA and obtains approval to begin the trial.

After the PMA is submitted, the FDA has 45 days to make a threshold determination that the PMA is sufficiently complete to permit a substantive review. If the PMA is complete, the FDA will file the PMA. The FDA is subject to a performance goal review time for a PMA that is 180 days from the date of filing, although in practice this review time is longer. Questions from the FDA, requests for additional data and referrals to advisory committees may delay the process considerably. The total process may take several years and there is no guarantee that the PMA will ever be approved. Even if approved, the FDA may limit the indications for which the device may be marketed. The FDA may also request additional clinical data as a condition of approval or after the PMA is approved. Any changes to the medical device may require a supplemental PMA to be submitted and approved before changed medical device may be marketed.

Any products sold by us pursuant to FDA clearances or approvals will be subject to pervasive and continuing regulation by the FDA, including record keeping requirements, reporting of adverse experiences with the use of the device and restrictions on the advertising and promotion of our products. In particular, we may not advertise or otherwise promote our devices for indications, patient populations, or other conditions of use that are not covered by the applicable FDA clearance or approval for the device. Modifications or changes to the device or how it is manufactured may also be separately subject to FDA review and authorization before being commercialized. Device manufacturers are required to register their establishments and list their devices with the FDA and are subject to periodic inspections by the FDA and certain state agencies. Noncompliance with applicable FDA requirements can result in, among other things, warning letters, fines, injunctions, civil penalties, recalls or seizures of products, total or partial suspension of production, refusal of the FDA to grant 510(k) clearance or PMA approval for new devices, withdrawal of 510(k) clearances and/or PMA approvals and criminal prosecution.

As a result of the SARS-CoV-2 pandemic, the US government declared a state of emergency which enabled the FDA to issue emergency use authorizations (EUAs) to provide more timely access to critical medical products (including medicines and tests) that may help

during the emergency when there are no adequate, approved, and available alternative options. EUAs are in effect until the emergency declaration ends but can be revised or revoked as FDA considers the needs during the emergency and new data on a product’s safety and effectiveness, or as products meet the criteria to become approved, cleared, or licensed by the FDA. Manufacturers of several types of SARS-CoV-2 assays have been granted EUAs. These authorizations are only intended for the duration of the emergency declaration, and afterwards will be revoked. The FDA has indicated the withdrawal of the EUA process will be done in a controlled ramp down.

Additionally, we may be required to conduct costly post-market testing, and we will be required to report adverse events and malfunctions related to our products. Later discovery of previously unknown problems with our products, including unanticipated adverse events of unanticipated severity or frequency, manufacturing problems, or failure to comply with regulatory requirements may result in restrictions on such products or manufacturing processes, withdrawal of the products from the market, voluntary or mandatory recalls, fines, suspension of regulatory approvals, product seizures, injunctions or the imposition of civil or criminal penalties.

Furthermore, the relevant authorities will inspect our facilities and those of our suppliers from time to time to determine whether we are in compliance with regulations relating to the manufacture of diagnostic products, including regulations concerning design, manufacture, testing, quality control, product labeling, distribution, promotion and record-keeping practices. A determination that we are in material violation of such regulations could lead to the imposition of civil penalties, including fines, product recalls, product seizures or, in extreme cases, criminal sanctions.

Canada Regulations

We also consider Canada as a target market with significant potential. Health Canada is the department of the Government of Canada responsible for national health policy, for both professional point-of-care and self-testing, which is similar to over-the-counter EUA authorization in the United States. Health Canada regulates, among other things, the research, development, testing, approval, manufacture, packaging, labeling, storage, recordkeeping, advertising, promotion, distribution, marketing, post-approval monitoring and import and export of pharmaceutical, including biologic, products. The process for obtaining regulatory approvals in Canada, along with subsequent compliance with applicable statutes and regulations, require the expenditure of substantial time and financial resources.

We may potentially be subject to product liability claims.

The testing of our T cell IVD/Immune response Test under the ViraxImmune brand entails an inherent risk of product liability claims. Further, providing clinical testing services entails a risk of claims for errors or omissions made by our laboratory staff. Potential liability claims may exceed the amount of our insurance coverage or may be excluded from coverage under the terms of the policy. As of the date of this report, we obtained a product liability insurance for the testing of the T cell IVD/Immune response Test under the ViraxImmune brand. Although we obtained product liability insurance for the testing of the T cell IVD/Immune response Test under the ViraxImmune brand, if any liability claims arise, it may result in:

Any of these outcomes may have an adverse effect on our consolidated results of operations, financial condition and cash flows, and may increase the volatility of our share price.

Our inadvertent or unintentional failure to comply with complex government regulations concerning privacy of medical and personal information could subject us to fines and adversely affect our reputation.

Privacy regulations around the world limit use or disclosure of protected personal information without written authorization or consent, except for permitted purposes outlined in the privacy regulations. The privacy regulations provide for significant fines and other penalties for wrongful use or disclosure of protected health information, including potential civil and criminal fines and penalties.

We have policies and practices that we believe make us compliant with the privacy regulations. Nevertheless, the documentation and process requirements of the privacy regulations are complex and subject to interpretation. Failure to comply with the privacy regulations could subject us to sanctions or penalties, loss of business and negative publicity.

Internationally, virtually every jurisdiction in which we operate has established its own data security and privacy legal framework with which we or our customers must comply, including the General Data Protection Regulation established in the European Union. We may also need to comply with varying and possibly conflicting privacy laws and regulations in other jurisdictions. As a result, we could face regulatory actions, including significant fines or penalties, adverse publicity and possible loss of business.

A disruption in our computer networks, including those related to cybersecurity, could adversely affect our financial performance.

Cybersecurity refers to the combination of technologies, processes and procedures established to protect information technology systems and data from unauthorized access, attack, or damage. We rely on our computer networks and systems, some of which are managed by third parties, to manage and store electronic information (including sensitive data such as confidential business information and personally identifiable data relating to employees, customers and other business partners), and to manage or support a variety of critical business processes and activities. Cyber-attacks are increasingly more common, including in the health care industry. The regulatory environment surrounding information security and privacy is increasingly demanding, with the frequent imposition of new and changing requirements. Compliance with changes in privacy and information security laws and with rapidly evolving industry standards may result in our incurring significant expense due to increased investment in technology and the development of new operational processes.

We have not experienced any known attacks on our information technology systems that have resulted in any material system failure, accident or security breach to date. However, we may face threats to our networks from unauthorized access, security breaches and other system disruptions. We maintain our information technology systems with safeguard protection against cyber-attacks, including passive intrusion protection, specialist security and virus detection software, use of two factor authentication to access systems and the education and training of staff. However, these safeguards do not ensure that a significant cyber-attack could not occur. Although we have taken steps to protect the security of our information systems and the data maintained in those systems, it is possible that our safety and security measures will not prevent the systems’ improper functioning or damage or the improper access or disclosure of personally identifiable information such as in the event of cyber-attacks.

Security breaches, including physical or electronic break-ins, computer viruses, attacks by hackers and similar breaches can create system disruptions or shutdowns or the unauthorized disclosure of confidential information. If personal information or protected health information is improperly accessed, tampered with or disclosed as a result of a security breach, we may incur significant costs to notify and mitigate potential harm to the affected individuals, and we may be subject to sanctions and civil or criminal penalties if we are found to be in violation of the privacy or security rules or other similar laws protecting confidential personal information. In addition, a cybersecurity breach could hurt our reputation by adversely affecting the perception of customers and potential customers of the security of their orders and personal information, subject us to liability claims or regulatory penalties for compromised personal information and could have a material adverse effect on our business, financial condition and results of operations.

We are subject to the U.K. Bribery Act and other anti-corruption laws, as well as export control laws, customs laws, sanctions laws and other laws governing our operations. If we fail to comply with these laws, we could be subject to civil or criminal penalties, other remedial measures, and legal expenses, which could adversely affect our business, results of operations and financial condition.

Our operations are subject to anti-corruption laws, including the Bribery Act and other anti-corruption laws that apply in countries where we do business. The Bribery Act and these other laws generally prohibit us and our employees and intermediaries from bribing, being bribed or making other prohibited payments to government officials or other persons to obtain or retain business or gain some other business advantage. We and our commercial partners operate in a number of jurisdictions that pose a high risk of potential Bribery Act violations, and we participate in collaborations and relationships with third parties whose actions could potentially subject us to liability under the Bribery Act or local anti-corruption laws. In addition, we cannot predict the nature, scope or effect of future regulatory requirements to which our international operations might be subject or the manner in which existing laws might be administered or interpreted.

We are also subject to other laws and regulations governing our international operations, including regulations administered by the governments of the United Kingdom and authorities in the European Union, including applicable export control regulations, economic sanctions on countries and persons, customs requirements and currency exchange regulations, collectively referred to as the Trade Control laws.

There is no assurance that we will be completely effective in ensuring our compliance with all applicable anti-corruption laws, including the Bribery Act, or other legal requirements, including Trade Control laws. If we violate provisions of the Bribery Act or other anti-corruption laws or Trade Control laws, we may be subject to criminal and civil penalties, disgorgement and other sanctions and remedial measures, and legal expenses, which could have an adverse impact on our business, financial condition, results of operations and liquidity. Likewise, any investigation into or audit of us of any potential violations of the Bribery Act and other anti-corruption laws or Trade Control laws by U.K. or other authorities could subject us to fines or criminal or other penalties, which could have an adverse impact on our reputation, our business, results of operations and financial condition.

Recent developments relating to the United Kingdom’s withdrawal from the European Union could adversely affect us.

The recent withdrawal of the United Kingdom from its membership in the European Union, or EU, often referred to as “Brexit”, could lead to legal and regulatory uncertainty in the United Kingdom and may lead to the United Kingdom and European Union adopting divergent laws and regulations, including those related to the pricing of prescription pharmaceuticals, as the United Kingdom determines which European Union laws to replicate or replace. If the United Kingdom were to significantly alter its regulations affecting the pricing of prescription pharmaceuticals, we could face significant new costs. As a result, Brexit could impair our ability to transact business in the European Union and the United Kingdom.

The United Kingdom and the EU have signed a EU-UK Trade and Cooperation Agreement, or TCA, which became provisionally applicable on January 1, 2021 and will become formally applicable once ratified by both the United Kingdom and the EU. This agreement provides details on how some aspects of the United Kingdom and EU’s relationship will operate going forwards however there are still many uncertainties. The uncertainty concerning the United Kingdom’s legal, political and economic relationship with the European Union may be a source of instability in the international markets, create significant currency fluctuations, and/or otherwise adversely affect trading agreements or similar cross-border co-operation arrangements (whether economic, tax, fiscal, legal, regulatory or otherwise).

These developments, or the perception that any of them could occur, have had, and may continue to have, a significant adverse effect on global economic conditions and the stability of global financial markets, and could significantly reduce global market liquidity and limit the ability of key market participants to operate in certain financial markets. In particular, it could also lead to a period of considerable uncertainty in relation to the United Kingdom financial and banking markets, as well as on the regulatory process in Europe. Asset valuations, currency exchange rates and credit ratings may also be subject to increased market volatility.

If other EU Member States pursue withdrawal, barrier-free access among the European Economic Area, or EEA, overall could be diminished or eliminated. The long-term effects of Brexit will depend on how the terms of the TCA take effect in practice and any further agreements (or lack thereof) between the United Kingdom and the EU. Such a withdrawal from the EU is unprecedented, and it is unclear how the UK access to the European single market for goods, capital, services and labor within the EU, and the wider commercial, legal and regulatory environment, will impact our United Kingdom operations.

We may also face new regulatory costs and challenges that could have an adverse effect on our operations and development programs. For example, the United Kingdom will lose the benefits of global trade agreements negotiated by the EU on behalf of its members, which may result in increased trade barriers that could make our doing business in the EU and the EEA more difficult. There may continue to be economic uncertainty surrounding the consequences of Brexit, which could adversely affect our financial condition, results of operations, cash flows and market price of our securities.

We are exposed to unanticipated changes in tax laws and regulations, adjustments to our tax provisions, exposure to additional tax liabilities, or forfeiture of our tax assets.

The determination of our provision for income taxes and other tax liabilities requires significant judgment, including the adoption of certain accounting policies and our determination of whether our deferred tax assets are, and will remain, tax effective. We cannot guarantee that our interpretation or structure will not be questioned by the relevant tax authorities, or that the relevant tax laws and regulations, or the interpretation thereof, including through tax rulings, by the relevant tax authorities, will not be subject to change. Any adverse outcome of such a review may lead to adjustments in the amounts recorded in our financial statements and could have a materially adverse effect on our operating results and financial condition.

We are subject to laws and regulations on tax levies and other charges or contributions in different countries, including transfer pricing and tax regulations for the compensation of personnel and third parties. Dealings between current and former group companies as well as additional companies that may form part of our group in the future are subject to transfer pricing regulations, which may be subject to change and could affect us. Compliance with these laws and regulations will be more challenging as we expand our international operations, including in connection with potential approvals of our product candidates in Europe, the United States and elsewhere.

Our effective tax rates could be adversely affected by changes in tax laws, treaties and regulations, both internationally and domestically, or the interpretation thereof by the relevant tax authorities, including possible changes to the corporate income tax base, wage withholding tax incentive for qualified research and development personnel in the United Kingdom and other tax incentives and the implementation of new tax incentives such as the innovation deduction. An increase of the effective tax rates could have an adverse effect on our business, financial position, results of operations and cash flows.

In addition, we may not be able to use, or changes in tax regulations may affect the use of, certain unrecognized tax assets or credits that we have built over the years. In general, some of these tax losses carry forwards may be forfeited in whole, or in part, as a result of various transactions, or their utilization may be restricted by statutory law in the relevant jurisdiction. Any corporate reorganization by us or any transaction relating to our shareholding structure may result in partial or complete forfeiture of tax loss carry forwards. The tax burden would increase if profits, if any, could not be offset against tax loss carry forwards.

Risk Related to our Corporate Structure

We may rely on dividends and other distributions on equity paid by our subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our subsidiaries to make payments to us could have a material adverse effect on our ability to conduct our business.

Virax Biolabs is a holding company incorporated in the Cayman Islands, and we may rely on dividends and other distributions on equity paid by our subsidiaries for our cash and financing requirements, including the funds necessary to pay dividends and other cash distributions to our shareholders and service any debt we may incur. If any of our subsidiaries incurs debt on its own behalf in the future, the instruments governing the debt may restrict its ability to pay dividends or make other distributions to us.

Under the current practice of the Inland Revenue Authority of Singapore, no tax is payable in Singapore in respect of dividends paid by us. Shareholders of a Cayman company will not be subject to any income, withholding or capital gains taxes in the Cayman Islands with respect to the holding of their shares in a Cayman company and dividends received on those shares, nor will they be subject to any estate or inheritance taxes in the Cayman Islands. There are no foreign exchange controls in the Cayman Islands. Under the Companies Act (Revised) of the Cayman Islands (the "Cayman Companies Act"), a Cayman company may declare and pay a dividend to shareholders from time to time out of the profits or out of the share premium account, provided that Virax Biolabs shall be able to pay its debts as they fall due in the ordinary course of business.

Any limitation on the ability of Virax Biolabs or UK subsidiaries to pay dividends or make other distributions to us could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends, or otherwise fund and conduct our business.

Risks Related to Our Securities

Our share price may be volatile and may fluctuate.

Like other biotechnology companies, the market price of our ordinary shares may be volatile. The factors below may also have a material adverse effect on the market price of our ordinary shares:

In addition, in the past, when the market price of a stock has been volatile, holders of that stock have instituted securities class action litigation against the issuer that issued the stock. If any of our shareholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit and divert the time and attention of our management, which could seriously harm our business.

If we fail to meet applicable listing requirements, Nasdaq may delist our ordinary shares from trading, in which case the liquidity and market price of our ordinary shares could decline.

We cannot assure you that we will be able to meet the continued listing standards of Nasdaq in the future. If we fail to comply with the applicable listing standards and Nasdaq delists our ordinary Shares, we and our shareholders could face significant material adverse consequences, including:

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Although the states are preempted from regulating the sale of our securities, the federal statute does allow the states to investigate companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case. Further, if we were no longer listed on Nasdaq, and if we are unable to list on another exchange, our securities would not be covered securities and we would be subject to regulations in each state in which we offer our securities.

We do not intend to pay cash dividends on our ordinary shares in the foreseeable future.

We have never paid dividends on ordinary shares and do not currently anticipate paying any cash dividends on our ordinary shares in the foreseeable future. The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. Our articles of association provide that our board of directors may declare and pay dividends if justified by our financial position and permitted by law. Our articles of association also provides that, subject to the Cayman Companies Act, the Company may also by ordinary resolution declare dividends in accordance with the respective rights of the shareholders but no dividend shall exceed the amount recommended by the directors.

Under Cayman Islands law, any payment of dividends would be subject to relevant legislation and our articles of association, which provide that all dividends must be approved by our board of directors and, in some cases, our shareholders, and may only be paid from our distributable profits available for the purpose, determined on an unconsolidated basis.

We are an emerging growth company within the meaning of the Securities Act and may take advantage of certain reduced reporting requirements.

We are an “emerging growth company,” as defined in the JOBS Act, and we may take advantage of certain exemptions from requirements applicable to other public companies that are not emerging growth companies, including, most significantly, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 for so long as we remain an emerging growth company. As a result, if we elect not to comply with such auditor attestation requirements, our investors may not have access to certain information they may deem important.

The JOBS Act also provides that an emerging growth company does not need to comply with any new or revised financial accounting standards until such date that a private company is otherwise required to comply with such new or revised accounting standards. We do not plan to “opt out” of such exemptions afforded to an emerging growth company. As a result of this election, our financial statements may not be comparable to those of companies that comply with public company effective dates.

We qualify as a foreign private issuer and, as a result, we will not be subject to U.S. proxy rules and will be subject to Exchange Act reporting obligations that permit less detailed and less frequent reporting than that of a U.S. domestic public company.

Upon the closing of the Company's IPO, we report under the Exchange Act as a non-U.S. company with foreign private issuer status. Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including (i) the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act; (ii) the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and (iii) the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Q

containing unaudited financial and other specified information, or current reports on Form 8-K upon the occurrence of specified significant events. In addition, our officers, directors and principal shareholders are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and the rules thereunder. Therefore, our shareholders may not know on a timely basis when our officers, directors and principal shareholders purchase or sell our ordinary shares. In addition, foreign private issuers are not required to file their annual report on Form 20-F until one hundred twenty (120) days after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within seventy-five (75) days after the end of each fiscal year. Foreign private issuers also are exempt from Regulation Fair Disclosure, aimed at preventing issuers from making selective disclosures of material information. As a result of the above, you may not have the same protections afforded to shareholders of companies that are not foreign private issuers.

If we lose our status as a foreign private issuer, we would be required to comply with the Exchange Act reporting and other requirements applicable to U.S. domestic issuers, which are more detailed and extensive than the requirements for foreign private issuers. We may also be required to make changes in our corporate governance practices in accordance with various SEC and Nasdaq rules. The regulatory and compliance costs to us under U.S. securities laws if we are required to comply with the reporting requirements applicable to a U.S. domestic issuer may be significantly higher than the cost we would incur as a foreign private issuer. As a result, we expect that a loss of foreign private issuer status would increase our legal and financial compliance costs and would make some activities highly time consuming and costly. We also expect that if we were required to comply with the rules and regulations applicable to U.S. domestic issuers, it would make it more difficult and expensive for us to obtain and maintain directors’ and officers’ liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified members of our board of directors.

As a foreign private issuer, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from Nasdaq corporate governance listing standards. These practices may afford less protection to shareholders than they would enjoy if we complied fully with corporate governance listing standards.

As a foreign private issuer, we are permitted to take advantage of certain provisions in the Nasdaq rules that allow us to follow our home country law for certain governance matters. Certain corporate governance practices in our home country, the Cayman Islands, may differ significantly from corporate governance listing standards. We have adopted Cayman Islands practices in lieu of certain requirements of Rule 5635 of the Nasdaq Stock Market LLC Rules which, among others, means we do not have to obtain shareholders' approval for certain dilutive events, such as (i) certain acquisition of stock or assets of another company; (ii) an issuance of shares that will result in a change of control of the company; (iii) the establishment or amendment of certain equity based compensation plans and arrangements; and (iv) certain transactions (other than a public offering) involving issuances of a 20% or more interest or voting power in the company at a price that is less than the minimum price defined therein. As such, our shareholders may be afforded less protection than they would otherwise enjoy under the Nasdaq corporate governance listing standards applicable to U.S. domestic issuers.

We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses.

As discussed above, we are a foreign private issuer, and therefore, we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act. The determination of foreign private issuer status is made annually on the last business day of an issuer’s most recently completed second fiscal quarter. We would lose our foreign private issuer status if, for example, more than 50% of our ordinary shares are directly or indirectly held by residents of the United States and we fail to meet additional requirements necessary to maintain our foreign private issuer status. If we lose our foreign private issuer status on this date, we will be required to file with the SEC periodic reports and registration statements on U.S. domestic issuer forms, which are more detailed and extensive than the forms available to a foreign private issuer. We will also have to mandatorily comply with U.S. federal proxy requirements, and our officers, directors and principal shareholders will become subject to the short-swing profit disclosure and recovery provisions of Section 16 of the Exchange Act. In addition, we will lose our ability to rely upon exemptions from certain corporate governance requirements under the Nasdaq rules. As a U.S. listed public company that is not a foreign private issuer, we will incur significant additional legal, accounting and other expenses that we will not incur as a foreign private issuer, and additional accounting, reporting and other expenses in order to maintain a listing on a U.S. securities exchange.

Nasdaq may apply additional and more stringent criteria for our continued listing because our insiders hold a large portion of our listed securities.

Under Listing Rule 5101, Nasdaq has discretionary authority to deny initial listing, apply additional or more stringent criteria for the initial or continued listing of particular securities, or suspend or delist particular securities based on any event, condition, or circumstance that exists or occurs that makes initial or continued listing of the securities on Nasdaq inadvisable or unwarranted in the opinion of Nasdaq, even though the securities meet all enumerated criteria for initial or continued listing on Nasdaq.

Additionally, Nasdaq has used its discretion to deny initial or continued listing or to apply additional and more stringent criteria in the instances, including but not limited to: (i) where the company engaged an auditor that has not been subject to an inspection by PCAOB, an auditor that PCAOB cannot inspect, or an auditor that has not demonstrated sufficient resources, geographic reach, or experience to

adequately perform the company’s audit; (ii) where the company planned a small public offering, which would result in insiders holding a large portion of the company’s listed securities. Nasdaq was concerned that the offering size was insufficient to establish the company’s initial valuation, and there would not be sufficient liquidity to support a public market for the company; and (iii) where the company did not demonstrate sufficient nexus to the U.S. capital market, including having no U.S. shareholders, operations, or members of the board of directors or management. Therefore, we may be subject to the additional and more stringent criteria of Nasdaq for our initial and continued listing.

Failure to comply with anti-corruption and anti-money laundering laws, including the FCPA and similar laws associated with activities outside of the United States, could subject us to penalties and other adverse consequences.

We are subject to the Foreign Corrupt Practices Act of 1977, as amended, 15 U.S.C. §§ 78dd-1, et seq., referred to as the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, the UK Bribery Act, and possibly other anti-bribery and anti-money laundering laws in countries in which we conduct activities. We face significant risks if we fail to comply with the FCPA and other anti-corruption laws that prohibit companies and their employees and third-party intermediaries from promising, authorizing, offering, or providing, directly or indirectly, improper payments or benefits to foreign government officials, political parties, and private-sector recipients for the purpose of obtaining or retaining business, directing business to any person, or securing any advantage. Any violation of the FCPA, other applicable anti-corruption laws, and anti-money laundering laws could result in whistleblower complaints, adverse media coverage, investigations, loss of export privileges, or severe criminal or civil sanctions, which could have a material adverse effect on our reputation, business, operating results, and prospects. In addition, responding to any enforcement action may result in a significant diversion of management’s attention and resources, significant defense costs, and other professional fees.

We incur significant costs as a result of being a public company, which may materially and adversely affect our business, financial condition and results of operations.

We incur costs associated with corporate governance requirements that are applicable to us as a public company, including rules and regulations of the SEC, under the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, and the Exchange Act, as well as the rules of the Nasdaq. These rules and regulations significantly increase our accounting, legal and financial compliance costs and make some activities more time-consuming and regulations to make it more expensive for us to obtain and maintain directors’ and officers’ liability insurance. As a result, it may be more difficult for us to attract and retain qualified persons to serve on our board of directors or as executive officers. Accordingly, increases in costs incurred as a result of being a publicly traded company may materially and adversely affect our business, financial condition and results of operations.

Securities analysts may not publish favorable research or reports about our business or may publish no information at all, which could cause our stock price or trading volume to decline.

The trading market will be influenced to some extent by the research and reports that industry or financial analysts publish about us and our business. We do not control these analysts. As a newly public company, we may be slow to attract research coverage and the analysts who publish information about our securities will have had relatively little experience with us or our industry, which could affect their ability to accurately forecast our results and could make it more likely that we fail to meet their estimates. In the event we obtain securities or industry analyst coverage, if any of the analysts who cover us provide inaccurate or unfavorable research or issue an adverse opinion regarding our stock price, our stock price could decline. If one or more of these analysts cease coverage of us or fail to publish reports covering us regularly, we could lose visibility in the market, which in turn could cause our stock price or trading volume to decline and result in the loss of all or a part of your investment in us.

Recently introduced economic substance legislation of the Cayman Islands may impact us and our operations.

Pursuant to the International Tax Cooperation (Economic Substance) Act, 2018 of the Cayman Islands, or the ES Act, that came into force on January 1, 2019, a “relevant entity” is required to satisfy the economic substance test set out in the ES Act. A “relevant entity” includes an exempted company incorporated in the Cayman Islands as is Virax Biolabs. There are nine designated "relevant activities" under the ES Act, and for so long as Virax Biolabs is carrying on activities which falls within any of the designated relevant activities, it shall comply with all applicable requirements under the ES Act. If the only business activity that Virax Biolabs carries on is to hold equity participation in other entities and only earns dividends and capital gains, then based on the current interpretation of the ES Act, Virax Biolabs is a “pure equity holding company” and will therefore only be subject to the minimum substance requirements, which require Virax Biolabs to (i) comply with the all applicable requirements under the Cayman Companies Act and (ii) have adequate human resources and adequate premises in the Cayman Islands for holding and managing equity participations in other entities. However, there can be no assurance that Virax Biolabs will not be subject to more requirements under the ES Act. Uncertainties over the interpretation and implementation of the ES Act may have an adverse impact on Virax Biolabs' business and operations.

Because we are incorporated under the laws of the Cayman Islands, our executive office is located in United Kingdom and the majority of our executive officers and directors are located outside the United States, you may face difficulties in protecting your interests, and your ability to protect your rights through the U.S. Federal or state courts may be limited.

We are holding company incorporated as an exempted company with limited liability incorporated under the laws of the Cayman Islands and our executive office is located in the United Kingdom. In addition, the majority of our executive officers and directors are located outside of the United States and are nationals or residents of jurisdictions other than the United States, and all or a substantial portion of their assets are located outside of the United States. Mr. James Foster, our Chief Executive Officer, chairman of the board of directors, holds a British Passport and currently resides in Shanghai, China; Dr. Nigel McCracken, our Chief Operating Officer, holds a British passport and currently resides in the United Kingdom; Mr. Yair Erez, our independent director, holds a British passport and currently resides in the United Kingdom; Mr. Evan Norton, our independent director, holds a United States passport and currently resides in the United States; and Mr. Nelson Haight, our independent director, holds a United States passport and currently resides in United States.

As a result, it may be difficult for investors to effect service of process within the United States upon us or these persons, or to enforce judgments obtained in U.S. courts against us or them, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States. A judgment of a United States court for civil liabilities predicated upon the federal securities laws of the United States may not be enforceable in or recognized by the courts of the jurisdictions where our directors and officers reside, and the judicial recognition process may be time-consuming. It may be difficult for you to enforce judgments obtained in U.S. courts based on the civil liability provisions of the U.S. federal securities laws against us and our officers and directors.

We have an U.S. office in Texas to receive service of process with respect to any action brought against us in the state or federal courts of the United States.

Our corporate affairs are governed by our memorandum and articles of association, the Cayman Companies Act and the common law of the Cayman Islands. The rights of shareholders to take action against our directors, actions by our minority shareholders and the fiduciary duties of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England and Wales, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary duties of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands have a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.

We have been advised by our Cayman Islands legal counsel that there is uncertainty as to whether the courts of the Cayman Islands would:

There is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islands will in certain circumstances recognize and enforce a foreign judgment, without any re-examination or re-litigation of matters adjudicated upon, provided such judgment:

Subject to the above limitations, in appropriate circumstances, a Cayman Islands court may give effect in the Cayman Islands to other kinds of final foreign judgments such as declaratory orders, orders for performance of contracts and injunctions.

Moreover, while under Delaware law, controlling shareholders owe fiduciary duties to the companies they control and their minority shareholders, under Cayman Islands law, our controlling shareholders do not owe any such fiduciary duties to our company or to our minority shareholders. Accordingly, our controlling shareholders may exercise their powers as shareholders, including the exercise of voting rights in respect of their shares, in such manner as they think fit in most circumstances.

Shareholders of Cayman exempted companies incorporated in the Cayman Islands like us have no general rights under Cayman Islands law to inspect corporate records (other than the memorandum and articles of association, and any special resolutions passed by such companies, and the registers of mortgages and charges of such companies) or to obtain copies of lists of shareholders of these companies. Our directors have discretion under our memorandum and articles of association to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders unless required by the Cayman Companies Act or other applicable law or authorized by the directors or by ordinary resolution. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

Certain corporate governance practices in our home country, the Cayman Islands, may differ significantly from corporate governance listing standards. We have adopted Cayman Islands practices in lieu of certain requirements of Rule 5635 of the Nasdaq Stock Market LLC Rules which, among others, means we do not have to obtain shareholders' approval for certain dilutive events, such as (i) certain acquisition of stock or assets of another company; (ii) an issuance of shares that will result in a change of control of the company; (iii) the establishment or amendment of certain equity based compensation plans and arrangements; and (iv) certain transactions (other than a public offering) involving issuances of a 20% or more interest or voting power in the company at a price that is less than the minimum price defined therein.

As a result of all of the above, our public shareholders may have more difficulty in protecting their interests in the face of actions taken by our management, members of our board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the United States.

Item 4. Information on the Company

A. History and Development of the Company.

Our legal name is Virax Biolabs Group Limited, and our commercial name is “Virax Biolabs.” We are an exempted company with limited liability incorporated under the laws of the Cayman Islands. Our principal executive offices are located at BioCity Glasgow, Bo’Ness Road, Newhouse, Lanarkshire, ML1 5UH. Our telephone number is +44 020 7788 7414.

Virax Biolabs is a holding company incorporated in the Cayman Islands. See Item 4.C. - Organizational Structure for the complete subsidiary hierarchy of the Company. In June 2022, Virax Cayman underwent a shareholding restructuring whereby the Company’s authorized share capital became a single class of ordinary shares and all of the then issued shares were re-designated as ordinary shares. In July 2022, the Company completed its IPO and began trading on the Nasdaq under the symbol “VRAX.”

We had $603,890 and $1,164,449 of capital expenditures associated with the purchase of property, plant and equipment, purchases of software, and investment in internally generated software for the year ended March 31, 2025 and 2024, respectively.

We use our website (http://www.viraxbiolabs.com) as a channel of distribution of Company information. The information we post on our website may be deemed material. Accordingly, investors should monitor the website, in addition to following our press releases, SEC filings and public conference calls and webcasts. The contents of our website are not, however, a part of this Annual Report on Form 20-F. In addition, the SEC maintains an internet site that contains reports, proxy and information statements, and other information regarding our filings and can be found at http://www.sec.gov.

Emerging Growth Company Status

As a company with less than US$1.235 billion in revenue for our last fiscal year, we qualify as an “emerging growth company” pursuant to the Jumpstart Our Business Startups Act of 2012, as amended, or the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other requirements compared to those that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 of the Sarbanes-Oxley Act of 2002 in the assessment of the emerging growth company’s internal control over financial reporting. The JOBS Act also provides that an emerging growth company does not need to comply with any new or revised financial accounting standards until such date that a private company is otherwise required to comply with such new or revised accounting standards. Pursuant to the JOBS Act, we have elected to take advantage of the benefits of this extended transition period for complying with new or revised accounting standards. As a result, our operating results and financial statements may not be comparable to the operating results and financial statements of other companies who have adopted the new or revised accounting standards.

We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year during which we have total annual gross revenues of at least US$1.235 billion; (ii) the last day of our fiscal year following the fifth anniversary of the completion of our IPO on July 25, 2022; (iii) the date on which we have, during the preceding three-year period, issued more than US$1.0 billion in non-convertible debt; or (iv) the date on which we are deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended, or the Exchange Act, which would occur if the market value of our ordinary shares that are held by non-affiliates exceeds

US$700 million as of the last business day of our most recently completed second fiscal quarter. Once we cease to be an emerging growth company, we will not be entitled to the exemptions provided in the JOBS Act discussed above.

Foreign Private Issuer Status

We are incorporated in the Cayman Islands, and (i) the majority of the company’s executive officers or directors are not U.S. citizens or residents; (ii) more than 50% of our assets are located out of the U.S.; and (iii) our business is administered principally out of the U.S. Therefore, we are a “foreign private issuer,” as defined in Rule 405 under the Securities Act and Rule 3b-4(c) under the Exchange Act. As a result, we are not subject to the same requirements as U.S. domestic issuers. Under the Exchange Act, we will be subject to reporting obligations that, to some extent, are more lenient and less frequent than those of U.S. domestic reporting companies. For example, we will not be required to issue quarterly reports or proxy statements. We will not be required to disclose detailed individual executive compensation information. Furthermore, our directors and executive officers will not be required to report equity holdings under Section 16 of the Exchange Act and will not be subject to the insider short-swing profit disclosure and recovery regime. In addition, as a company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the Nasdaq Stock Market corporate governance requirements. These practices may afford less protection to shareholders than they would enjoy if we complied fully with the Nasdaq Stock Market corporate governance requirements.

B. Business overview.

The Company's mission is to protect people from viral diseases and help with the early diagnosis of post viral syndromes associated with T cell exhaustion and chronic inflammation through the provision of diagnostic tests and tests for adaptive immunity.

The Company is in the process of developing ViraxImmune, with the intention of providing an immunology profiling platform that assesses each individual’s immune risk profile against major global viral diseases as well as helping with the early diagnosis of post viral syndromes associated with T cell exhaustion and chronic inflammation. We are in the process of developing a T cell Test under the ViraxImmune brand and will apply for regulatory agency approval in the future. We believe that the T cell Tests and immunology platform we are developing under the ViraxImmune brand will be particularly useful in assisting in the threat analysis of the major viruses faced globally as well as helping with the early diagnosis of indications associated with T cell exhaustion and chronic inflammation which have been linked to symptoms such as chronic fatigue. Initially, we will be focusing in diseases associated with post viral syndromes including but not limited to SARS-CoV-2, Human Papillomavirus (better known as HPV), Malaria, Hepatitis B, and Herpes (better known as HSV-1). We are preparing a Q-submission under the U.S. Food and Drug Administration (FDA) pre-submission program for potential IVD classification of our ViraxImmune assay and anticipate holding the Q-submission meeting during the third quarter of 2025.

The Company also has the ability to distribute existing diagnostics test kits through our ViraxClear and ViraxVet brands. Currently, we do not manufacture or develop any product that we sell in our ViraxClear and ViraxVet product portfolios, and we act as a distributor of third-party suppliers’ products. While ViraxClear and ViraxVet have the ability to sell and distribute existing test kits, they are not the main focus of the Company.

Share Consolidation

The Company's board of directors and shareholders approved a 1-for-10 share consolidation (the “Share Consolidation”) on November 3, 2023 and December 6, 2023, respectively. The Company filed the third amended and restated articles of association (the “Post-Split Amended and Restated Articles of Association”), which became effective on December 18, 2023. Beginning with the opening of trading on December 18, 2023, the Company's ordinary shares began trading on a post-Share Consolidation basis on the Nasdaq Capital Market under the same symbol "VRAX", but under a new CUSIP number of G9495L125. The objective of the Share Consolidation was to enable the Company to regain compliance with Nasdaq Marketplace Rule 5550(a)(2) and maintain its listing on the Nasdaq Capital Market. On January 4, 2024, the Company received notification that it had regained compliance with Nasdaq Marketplace Rule 5550(a)(2).

Upon the effectiveness of the Share Consolidation, every ten issued and outstanding ordinary shares of a par value of US$0.0001 each was automatically consolidated into one issued and outstanding ordinary share of a par value of US$0.001 each. No fractional shares

were issued as a result of the Share Consolidation. Instead, any fractional shares that would have resulted from the Share Consolidation were rounded up to the next whole number. The Share Consolidation affected all shareholders uniformly and did not alter any shareholder's percentage interest in the Company's outstanding ordinary shares, except for adjustments that may result from the treatment of fractional shares. As such, all share and per share amounts have been given retroactive effect in the financial statements for all periods presented.

Our Products and Services

ViraxClear and ViraxVet

Our existing, minor product portfolio consists of IVD test kits which we have the ability to distribute through our ViraxClear and ViraxVet brands. Currently, we do not manufacture or develop any product that we may sell and we act as a distributor of third-party suppliers’ products. For the fiscal year ended March 31, 2025, revenues generated from these brands were immaterial and accounted for 100% of our total revenues.

The Company has the ability to distribute primarily the following existing test kits under the ViraxClear and ViraxVet brands:

ViraxImmune

ViraxImmune is our brand under development and also our primary focus in the near future. We are in the process of developing a comprehensive set of T cell diagnostics and immune profiling solutions. Our strategic focus is the development and commercialization of immune profiling IVDs in indications associated with chronic inflammation and T cell exhaustion, such as post viral syndromes and other infectious diseases, chronic inflammation and immune-oncology.

The potential applications of ViraxImmune are not restricted to any single disease or condition. The platform's capabilities will initially focus on measuring chronic inflammation associated with T cell exhaustion in areas such as SARS-CoV-2 effects, Chimeric Antigen Receptor T cell (CAR-T) therapies, Myloid, Encephalomyelitis (ME) and post viral syndromes. This versatility will position ViraxImmune as a comprehensive platform capable of potentially addressing a wide range of research, diagnostic and health needs within indications associated with chronic inflammation and T cell exhaustion.

Post-viral syndromes are a wide range of complex conditions involving physical, cognitive, emotional and neurological difficulties that vary in severity over time. These conditions frequently lead to a sense of tiredness and weakness, pain, difficulty concentrating and headaches that linger after the viral infection has cleared. Symptoms may continue for weeks, months or longer. Various microbial and viral infections are possible trigger factors for post-viral syndrome, including SARS-CoV-2, Epstein-Barr virus, cytomegalovirus, human herpesvirus, enteroviruses, HPV, Lyme disease and Zika, among others.

The diagnosis of these conditions can be very difficult among sufferers who are often neglected by healthcare systems that are unable to identify a definitive diagnosis and treatment strategy. The first point of diagnosis should be identifying that there is an issue and pinpointing the initial cause. The ViraxImmune diagnostic test may help to identify if an individual is suffering from a post-viral syndrome and also elucidate the original viral cause of the condition. The ViraxImmune diagnostic may also identify elements associated with these conditions, such as a persistent cytokine response in addition to T cell exhaustion.

As an example Long COVID represents a significant public health challenge in the post-SARS-CoV-2 era. Epidemiological studies indicate that 10-30% of individuals infected with SARS-CoV-2 experience persistent symptoms beyond the acute phase of the infection. These symptoms, including chronic fatigue, cognitive dysfunction, and respiratory difficulties, persistently affect patient health and quality of life. The heterogeneity of these symptoms complicates the diagnostic process, as they overlap with a range of other post-viral syndromes, posing a challenge to healthcare professionals. The diagnostic tools currently available such as primarily PCR and lateral flow tests, are optimized for acute viral infection detection and do not adequately address the chronic and complex nature of Long COVID. Consequently, many patients experience a diagnostic ambiguity, impacting their subsequent treatment and care. This challenge is exacerbated by the high prevalence of SARS-CoV-2 exposure, both through infection and vaccination, necessitating the development of diagnostic methods specifically tailored to Long COVID.

The primary markets of interest will be the United Kingdom and North America due to a rise in chronic infections, rising healthcare expenditures, a well-developed healthcare sector, large patient population, and government support for research and development. Virax Biolabs will also look to gain regulatory approval of the IVDs in these territories followed by the European Union. The key revenue streams are anticipated to be healthcare providers treating patients, and researchers and drug companies developing treatments in the indications of interest.

The Company intends to initially launch a number of T cell immune profiling assays in different indications as research-use-only ("RUO") followed by the later release of IVDs centered around T cell exhaustion and chronic inflammation through the ViraxImmune platform. The development of a fully approved IVD will involve performing the appropriate analytical and clinical performance studies required as part of the regulatory requirements in the different territories. As part of the development of the in-vitro diagnostic ("IVD") the Company intends to work alongside the appropriate governmental healthcare providers to allow the test to be incorporated into the healthcare system and pharmacy outlets. All intellectual property rights developed during the course of the research and development activities will belong to the Company. To guarantee the relevance of our clinical evidence, the study protocol will be discussed with the FDA and MHRA (UK) via a pre-submission process for guidance prior to the start of any clinical performance study. We are preparing a Q-submission under the U.S. Food and Drug Administration (FDA) pre-submission program for potential IVD classification of our ViraxImmune assay and anticipate holding the Q-submission meeting during the third quarter of 2025.

Our Industry

Our Company competes in the IVD market. The IVD tests are defined as medical devices and reagents that are used to analyze specimens derived from the human body (including blood, tissues, and other body fluids) to detect diseases, conditions, and infections. IVD tests are usually performed at either stand-alone laboratory, hospital-based laboratory, or point-of-care (“POC”) centers. The technologies used for test sample preparation majorly include polymerase chain reaction (“PCR”), microarray techniques, sequencing technology, and mass spectrometry. Based on the key technologies involved, the global IVD market is fragmented into sub-segments including Immunoassay, Hematology, Clinical Chemistry, Molecular Diagnostics, Microbiology, Haemostasias, Flow Cytometry and others.

The IVD sector is expected to experience growth rates owing to driving factors such as aging global population, increase in the occurrence of complex infectious diseases, an increase in awareness among the global urban populations, etc. However, lack of proper reimbursement policies in the developing nations and skepticism among patients to get regular healthcare consulting are still hindrances in some regions, especially third-world countries, which impedes the growth of the IVD market.

Key Supplier Relationships

We source our suppliers through multiple channels through referrals from counterparties and through industry exhibitions/expos. Our suppliers are divided into two categories: (1) those manufacturing our products as per our manufacturing standards, and (2) those providing products for our distribution. Our Company works closely with our suppliers to assure continuity of supply while maintaining high quality and reliability. To date, our Company has not experienced any significant difficulty in locating and obtaining the materials necessary to fulfill our production schedules.

Key Customer Relationships

Our Company has two types of customers: (i) direct end user customers, which may include research organizations, corporations, independent laboratories, large hospital systems and public and private institutions, and (ii) distributor customers, which distribute our own brands and products we sourced from third party suppliers.

Our Competitive Strengths

We believe the following competitive strengths differentiate us from our competitors and will continue to contribute to our success:

Cutting-edge technology

Our Company is engaged in creating a cutting-edge technology. In particular, our in-development ViraxImmune’s immunological diagnostic profiling technique is intended to be cutting-edge technology which we believe is not currently available on the IVD market as at the date of this report. Currently, we are in the process of developing a comprehensive set of T cell diagnostics and immune profiling solutions. Our strategic focus is the development and commercialization of immune profiling IVDs in indications associated with chronic inflammation and T cell exhaustion, such as post viral syndromes and other infectious diseases, chronic inflammation and immune-oncology.

The potential applications of ViraxImmune are not restricted to any single disease or condition. The platform's capabilities will initially focus on measuring chronic inflammation associated with T cell exhaustion in areas such as SARS-CoV-2 effects, Chimeric Antigen Receptor T cell (CAR-T) therapies, Myloid, Encephalomyelitis (ME) and post viral syndromes. This versatility will position ViraxImmune as a comprehensive platform capable of potentially addressing a wide range of research, diagnostic and health needs within indications associated with chronic inflammation and T cell exhaustion.

Commercialization of our own diagnostic devices

Historically in-vitro diagnostic test kits are designed to be lab specific by leading biotechnology and pharmaceutical companies, and thus, an in-vitro diagnostic test kit company is required to be tied down to a specific biotechnology partner or pharmaceutical partner. However, we are designing our ViraxImmune T cell IVD/Immune response Test kit to be as lab agnostic and easy to use as possible. As a result, we believe this will allow us to distribute the T cell in-vitro diagnostics test kit to a broader geographic reach and deploy the test kits rapidly, without having to impose difficult techniques or equipment on our lab partners or being tied down to a specific lab partner. As a result, we believe we can rapidly capture the T cell in-vitro diagnostics test kit market share in a short period of time.

We are concentrating on developing diagnostics for the early diagnosis for post viral syndromes and indications associated with chronic inflammation and T cell exhaustion as there is a major medical need for early detection to enable early treatment interventions. The primary markets of interest will be the United Kingdom, the European Union and North America due to a rise in chronic infection, rising healthcare expenditures, a well-developed healthcare sector, rising healthcare expenditures, large patient population, and government support for research and development.

Experienced Management Team with Extensive Industry Expertise and a Global Vision

Our Company has an experienced management team driven by a shared passion for the prevention, detection, diagnosis and risk management of viral diseases, particularly immunology. Our Company is led by our chief executive officer, Mr. James Foster, who had entrepreneurial successes in various investment companies before co-founding Virax. In 2009, Mr. Foster co-founded Cryptex Card, one of the world's first global debit card companies for Bitcoin. In 2013, Mr. Foster co-founded Natural Source Group Pte. Limited, a company which received venture capital funding. Our Chief Operating Officer is Dr. Nigel McCracken. Prior to joining Virax, Dr. McCracken was the Chief Scientific Officer at OTC traded BerGenBio AsA where he drove the plan for BerGenBio AsA's companion diagnostics and assay development. Prior to that role, he served as COO at Nasdaq listed NuCana PLC, a clinical-stage biopharmaceutical company focused on significantly improving treatment outcomes for patients with cancer, where he provided oversight and direction to the operations of the business, research and development, and execution of corporate strategy. Dr. McCracken obtained a Master's degree in Clinical Pharmacology from Kings College London, a Doctor of Philosophy degree in Biochemical Toxicology from the University of Newcastle Upon Tyne, and a Bachelor of Science degree in Biochemistry and Pharmacology from Strathclyde University. Other members of our management team are also industry veterans with diverse expertise, such as in developing advanced technology platforms, as well as overseeing investments, financing and other corporate development initiatives of various companies, and possess keen insights into the latest trends in the global healthcare and pharmaceutical market.

Expanding Research and Development Capabilities

Our Company has and is continuing to invest significant resources in research and development. For the years ended March 31, 2025, 2024 and 2023, our research and development expenses were $1,779,802, $1,561,965 and $2,179,341 respectively. As of March 31,

2025, we have an intellectual property portfolio consisting of 3 pending trademarks and 4 registered domain names. We have built a strong research and development team and are developing a T cell IVD/Immune response Test kit under the ViraxImmune brand and will initially focus on measuring chronic inflammation associated with T cell exhaustion in areas such as SARS-CoV-2 effects, Chimeric Antigen Receptor T cell (CAR-T) therapies, Myloid, Encephalomyelitis (ME) and post viral syndromes. We will subsequently be addressing a wide range of research, diagnostic and health needs within indications associated with chronic inflammation and T cell exhaustion. As of March 31, 2025, our research and development team was composed of 13 personnel, which accounted for approximately 68% of our total employees. Our research and development team has years of technology know-how in developing and launching products and services in response to market demands. We believe this can lead to a shorter time to market which in turn may allow us to fully capture opportunities presented by shifts in industry trends. Further, our in-house research and development team collaborate closely with our manufacturing and research and development partners to ensure our products receive timely updates and/or the new biotechnology to keep abreast of global outbreaks of viral diseases.

Our Strategies

Development of the proprietary ViraxImmune suite of IVD T cell test kits.

Post-viral syndromes are a wide range of complex conditions involving physical, cognitive, emotional and neurological difficulties that vary in severity over time. These conditions frequently lead to a sense of tiredness and weakness, pain, difficulty concentrating and headaches that linger after the viral infection has cleared. Symptoms may continue for weeks, months or longer. Various microbial and viral infections are possible trigger factors for post-viral syndrome, including SARS-CoV-2, Epstein-Barr virus, cytomegalovirus, human herpesvirus, enteroviruses, HPV, Lyme disease and Zika, among others.

The diagnosis of these conditions can be very difficult among sufferers who are often neglected by healthcare systems that are unable to identify a definitive diagnosis and treatment strategy. The first point of diagnosis should be identifying that there is an issue and pinpointing the initial cause. The ViraxImmune diagnostic test may help to identify if an individual is suffering from a post-viral syndrome and also elucidate the original viral cause of the condition. The ViraxImmune diagnostic may also identify elements associated with these conditions, such as a persistent cytokine response in addition to T cell exhaustion. For further details on ViraxImmune, see “Our Products and Services — ViraxImmune” in this section.

Launch Expanded Sales and Marketing.

We intend to strengthen and expand our sales and marketing efforts by utilizing the following strategies, among others:

Sales, Distribution, Marketing and Advertising

Our Company is continuing to build sales and distribution networks.

Our marketing strategy will largely focus on educating consumers, in particular corporate consumers, about our products as everyone may potentially be susceptible to a viral disease. We also plan to focus on clinics, pharmacies, laboratories, hospitals, and other relevant groups once we receive regulatory approval for our ViraxImmune product. We will use a combination of techniques in our marketing approach including but not limited to social media campaigns and public relations.

Research and Development

For years ended March 31, 2025, 2024 and 2023, our research and development expenses amounted to $1,779,802, $1,561,965 and $2,179,341, respectively. As of March 31, 2025, our internal research and development team was composed of 13 personnel, who have expertise in developing and manufacturing diagnostics as well as expertise in immunology and within infectious disease and oncology.

Our research and development strategy has been centered on:

Intellectual Property

Our success and future revenue growth depend, in part, on our ability to protect our intellectual property. We will rely primarily on copyright, trademark and trade secret laws, as well as confidentiality procedures, to protect our proprietary technologies and processes.

We believe that the core of our business is comprised of our proprietary technologies. As a result, we will strive to maintain a robust intellectual property portfolio. Our success and future revenue growth may depend, in part, on our ability to protect our intellectual property as products and services that are material to our operating results will incorporate patented technology.

Although we currently do not have any active patents or pending patent applications, our proprietary immune profiling technologies are underpinned by internally developed methods, trade secrets, and confidential know-how. We are actively evaluating patent filings to protect ongoing innovations.

We believe our rights to future patents, if any, copyrights, trademarks and other intellectual property rights will serve to distinguish and protect our products from infringement and contribute to our competitive advantages.

Competition

We face significant competition in our evolving industries from numerous competitors, particularly the in-vitro diagnostics industry. To differentiate us from other in-vitro diagnostics providers in the industry, we focus on cutting-edge technology capable of potentially addressing a wide range of research, diagnostic and health needs within indications associated with chronic inflammation and T cell exhaustion.

Participants in the in-vitro diagnostics industry include biotechnology companies, established pharmaceutical companies, and other in-vitro diagnostics companies. Many of our competitors developed in-vitro diagnostic test kits and other products similar to us. As of the date of this report, we consider our main IVD competitors to be Qiagen N.V. (NYSE: QGEN), Adaptive Biotechnologies Corporation (NASDAQ: ADPT), Roche Holding AG (SIX: ROG) and Abbott Laboratories (NYSE: ABT). We may also face competition from new and emerging companies.

Compared to our company, our current and potential competitors may have:

However, we believe we are well positioned to compete in the in-vitro diagnostics market as a result of our comprehensive product portfolio, research and development capabilities, and experienced management team.

The principal competitive factors in the in-vitro diagnostics market include:

We believe we compete favorably with respect to the factors mentioned above.

Regulations

This section sets forth a summary of the significant regulations or requirements in the jurisdictions where we conduct our material business operations, namely the United Kingdom, the United States and the European Union.

United Kingdom

The UK’s withdrawal from the EU will have major ramifications for IVD manufacturers that will, among other things have to follow new procedures that will apply in the UK including appointment of a UK Responsible Person rather than relying on European Authorized Representatives to manage their compliance efforts in the UK.

IVDs compliant with the EU in vitro diagnostic medical devices regulation (EU IVDD) can be placed on the Great Britain market up until the 30 June 2030. We intend to use the recognized CE marks that we will apply with the European Union for our medical device product, namely our current in development T cell IVD Test under the ViraxImmune brand. After which, we will apply with the UK Medicine and Healthcare Products Regulatory Agency for a UK Conformity Assessed mark.

United States

The FDA regulates the sale or distribution of medical devices, including but not limited to IVD test kit. IVD products are subject to regulations by the FDA as medical devices to the extent that they are intended for use in the diagnosis, treatment, cure, mitigation or prevention of disease or other conditions.

The information that must be submitted to the FDA in order to obtain clearance or approval to market a new medical device varies depending on how the medical device is classified by the FDA. Medical devices are classified into one of three risk-based classes depending on the controls deemed by the FDA to be necessary to reasonably ensure their safety and effectiveness. Class I devices are considered the lowest risk and are subject to general controls, including labeling requirements, and adherence to the FDA’s quality system regulations, or QSRs, which are device-specific current good manufacturing practices. Class II (intermediate risk) devices may be subject to premarket notification, or may be 510(k)-exempt, and are generally subject to QSRs, general controls and sometimes special controls, including performance standards and post-market surveillance. Class III (highest risk) devices are subject to most of the previously identified requirements as well as to pre-market approval. Class I devices are exempt from premarket review; most Class II devices require 510(k) clearance, and all Class III devices must receive premarket approval before they can be sold in the United States. The payment of a user fee, which is typically adjusted annually, to the FDA is usually required when a 510(k) notice or premarket approval application is submitted.

510(k) Premarket Notification

A 510(k) premarket notification requires the sponsor to demonstrate that a medical device is substantially equivalent to another marketed device, termed a “predicate device,” that is legally marketed in the United States and for which a premarket approval was not required. A device is substantially equivalent to a predicate device if it has the same intended use and technological characteristics as the predicate; or has the same intended use but different technological characteristics, where the information submitted to the FDA does not raise new questions of safety and effectiveness and demonstrates that the device is at least as safe and effective as the legally marketed device.

If the FDA believes that the device is not substantially equivalent to a predicate device, it will issue a “Not Substantially Equivalent” (“NSE”) determination and designate the device as a Class III device, which will require the submission and approval of a PMA before the new device may be marketed. A person who receives an NSE determination in response to a 510(k) submission may, within 30 days of receipt of the NSE determination, submit a de novo request for the FDA to make a risk-based evaluation for classification of the device into Class I or II. Devices that are classified through the de novo process may be marketed and used as predicates for future 510(k) submissions. The FDA continues to reevaluate the 510(k) pathway and process and the de novo process, and has taken what it describes as a risk-based approach to develop innovative regulatory policy to propose a more “contemporary” approach. In October 2017, the FDA published a final guidance entitled, “De Novo Classification Process (Evaluation of Automatic Class III Designation),”

and in December 2018, the FDA published a proposed rule which if finalized is intended to provide structure, clarity and transparency on the de novo classification process. In January 2021, it also published a final guidance entitled “Requests for Feedback and Meetings for Medical Device Submissions: The Q-Submission Program.”

Pre-market Approval (“PMA”)

A PMA must be supported by more detailed and comprehensive scientific evidence, including clinical data, to demonstrate the safety and efficacy of the medical device for its intended purpose. If the device is determined to present a “significant risk,” the sponsor may not begin a clinical trial until it submits an investigational device exemption (“IDE”) to the FDA and obtains approval to begin the trial.

After a PMA is submitted, the FDA has 45 days to make a threshold determination that the PMA is sufficiently complete to permit a substantive review. If the PMA is complete, the FDA will file the PMA. The FDA is subject to a performance goal review time for a PMA that is 180 days from the date of filing, although in practice this review time is longer. Questions from the FDA, requests for additional data and referrals to advisory committees may delay the process considerably. The total process may take several years and there is no guarantee that the PMA will ever be approved. Even if approved, the FDA may limit the indications for which the device may be marketed. The FDA may also request additional clinical data as a condition of approval or after the PMA is approved. Any changes to the medical device may require a supplemental PMA to be submitted and approved before changed medical device may be marketed.

Any products sold by us pursuant to FDA clearances or approvals will be subject to pervasive and continuing regulation by the FDA, including record keeping requirements, reporting of adverse experiences with the use of the device and restrictions on the advertising and promotion of our products. In particular, we may not advertise or otherwise promote our devices for indications, patient populations, or other conditions of use that are not covered by the applicable FDA clearance or approval for the device. Modifications or changes to the device or how it is manufactured may also be separately subject to FDA review and authorization before being commercialized. Device manufacturers are required to register their establishments and list their devices with the FDA and are subject to periodic inspections by the FDA and certain state agencies. Noncompliance with applicable FDA requirements can result in, among other things, warning letters, fines, injunctions, civil penalties, recalls or seizures of products, total or partial suspension of production, refusal of the FDA to grant 510(k) clearance or PMA approval for new devices, withdrawal of 510(k) clearances and/or PMA approvals and criminal prosecution.

As a result of the SARS-CoV-2 pandemic, the US government declared a state of emergency which enabled the FDA to issue emergency use authorizations (“EUAs”) to provide more timely access to critical medical products (including medicines and tests) that may help during the emergency when there are no adequate, approved, and available alternative options. EUAs are in effect until the emergency declaration ends but can be revised or revoked as FDA considers the needs during the emergency and new data on a product’s safety and effectiveness, or as products meet the criteria to become approved, cleared, or licensed by the FDA. Manufacturers of several types of SARS-CoV-2 assays have been granted EUAs. These authorizations are only intended for the duration of the emergency declaration, and afterwards will be revoked. The FDA has indicated the withdrawal of the EUA process will be done in a controlled ramp down.

Additionally, we may be required to conduct costly post-market testing, and we will be required to report adverse events and malfunctions related to our products. Later discovery of previously unknown problems with our products, including unanticipated adverse events of unanticipated severity or frequency, manufacturing problems, or failure to comply with regulatory requirements may result in restrictions on such products or manufacturing processes, withdrawal of the products from the market, voluntary or mandatory recalls, fines, suspension of regulatory approvals, product seizures, injunctions or the imposition of civil or criminal penalties.

Furthermore, the relevant authorities will inspect our facilities and those of our suppliers from time to time to determine whether we are in compliance with regulations relating to the manufacture of diagnostic products, including regulations concerning design, manufacture, testing, quality control, product labeling, distribution, promotion and record-keeping practices. A determination that we are in material violation of such regulations could lead to the imposition of civil penalties, including fines, product recalls, product seizures or, in extreme cases, criminal sanctions.

PRC laws and regulations applicable to Shanghai Xitu

As illustrated in “Corporate History and Structure” Shanghai Xitu Consulting Co., Limited (“Shanghai Xitu”) is our Company's sole PRC subsidiary. Shanghai Xitu is a wholly owned subsidiary of Logico BVI, and is classified as a wholly foreign owned enterprise (“WFOE”) under PRC law.

Regulations Related to Business Registration

According to the Foreign Investment Law of China released by The National People’s Congress of the People’s Republic of China on March 15, 2019, to set up a WFOE in China:

The Special Administrative Measures (Negative List) for Foreign Investment Access (Edition 2021) released by the National Development and Reform Commission (“NDRC”) and MOFCOM on 27 December 2021 have set out the industries in which foreign investment is prohibited or restricted. If a PRC company engages in business in certain industries (such as the finance industry), it may need to obtain special license or approval from the relevant authority in addition to its business license.

Each PRC company has a “business scope” set out on its business license. The PRC company may conduct business within such scope. Further, according to the current PRC law and legal practice, a company may also conduct activities outside of its registered business scope unless any special license/approval is required for such additional business activities.

Upon management's review, Shanghai Xitu has obtained the Foreign Investment Approval Certificate issued by the MOFCOM. The registered business scope of Shanghai Xitu as shown on its business license is as follows: “business information consultation, business management consultation, business registration agency, marketing planning, corporate image planning, conference services (except for hosting, undertaking, and exhibitions), exhibition services (hosting, undertaking, excluding exhibitions), technology development in the field of network technology, proprietary technology transfer, technology consulting, and technical services.”

Upon management's review of the Negative List and Business Scope Specification Expression Query System, as at the date of this report, the registered business scope of Shanghai Xitu is not on the Negative List. As a result, there is no prohibition or restriction on foreign investment in such industries.

In addition, Shanghai Xitu does not need to obtain any special license or approval granted by the relevant authority for it to conduct business within its registered business scope. The business license of Shanghai Xitu is sufficient for it to conduct its registered business scope. Upon management's review, Shanghai Xitu is primarily engaged in procurement.

Shanghai Xitu’s current business is not stated on its registered business scope. As stated at above, a PRC company may conduct activities outside of its registered business scope unless any special license/approval is required for such additional business activities. For such current business of Shanghai Xitu, it is not required to obtain any special license/approval. Therefore, Shanghai Xitu may conduct such activities beyond its registered business scope.

See “Forward-Looking Statements” for a discussion of the uncertainties, risks and assumptions associated with these statements. Actual results and the timing of events could differ materially from those discussed in our forward-looking statements as a result of many factors, including those set forth under “Risk Factors” and elsewhere in this annual report.

A. Operating results.

Overview

Virax Biolabs is a holding company incorporated as an exempted company under the laws of the Cayman Islands. As a holding company with no material operations of its own, it conducts the majority of its operations through its subsidiaries in the United Kingdom, the United States, and China and has been operating since 2013.

The Company is a global innovative biotechnology company focused on the prevention, detection, diagnosis, and risk management of viral diseases with a current focus on the field of T cell in Vitro Diagnostics. The Company is in the process of developing and manufacturing tests that can predict adaptive immunity to viral diseases as well as identify individuals suffering from T cell exhaustion and chronic inflammation linked to post viral syndromes. The Company's mission is to protect people from viral diseases and help with the early diagnosis of post viral syndromes associated with T cell exhaustion and chronic inflammation through the provision of diagnostic tests and tests for adaptive immunity.

The Company is in the process of developing ViraxImmune, with the intention of providing an immunology profiling platform that assesses each individual’s immune risk profile against major global viral diseases as well as helping with the early diagnosis of post viral syndromes associated with T cell exhaustion and chronic inflammation. We are in the process of developing a T cell Test under the ViraxImmune brand and will apply for regulatory agency approval in the future. We believe that the T cell Tests and immunology platform we are developing under the ViraxImmune brand will be particularly useful in assisting in the threat analysis of the major viruses faced globally as well as helping with the early diagnosis of indications associated with T cell exhaustion and chronic inflammation which have been linked to symptoms such as chronic fatigue. Initially, we will be focusing in diseases associated with post viral syndromes including but not limited to SARS-CoV-2, Human Papillomavirus (better known as HPV), Malaria, Hepatitis B, and Herpes (better known as HSV-1). We are preparing a Q-submission under the U.S. Food and Drug Administration (FDA) pre-submission program for potential IVD classification of our ViraxImmune assay and anticipate holding the Q-submission meeting during the third quarter of 2025.

The Company also has the ability to distribute existing diagnostics test kits through our ViraxClear and ViraxVet brands. Currently, we do not manufacture or develop any product that we sell in our ViraxClear and ViraxVet product portfolios, and we act as a distributor of third-party suppliers’ products. While ViraxClear and ViraxVet have the ability to sell and distribute existing test kits, they are not the main focus of the Company.

Share Consolidation

The Company's board of directors and shareholders approved a 1-for-10 share consolidation (the “Share Consolidation”) on November 3, 2023 and December 6, 2023, respectively. The Company filed the third amended and restated articles of association (the “Post-Split Amended and Restated Articles of Association”), which became effective on December 18, 2023. Beginning with the opening of trading

on December 18, 2023, the Company's ordinary shares began trading on a post-Share Consolidation basis on the Nasdaq Capital Market under the same symbol "VRAX", but under a new CUSIP number of G9495L125. The objective of the Share Consolidation was to enable the Company to regain compliance with Nasdaq Marketplace Rule 5550(a)(2) and maintain its listing on the Nasdaq Capital Market. On January 4, 2024, the Company received notification that it had regained compliance with Nasdaq Marketplace Rule 5550(a)(2).

Upon the effectiveness of the Share Consolidation, every ten issued and outstanding ordinary shares of a par value of US$0.0001 each was automatically consolidated into one issued and outstanding ordinary share of a par value of US$0.001 each. No fractional shares were issued as a result of the Share Consolidation. Instead, any fractional shares that would have resulted from the Share Consolidation were rounded up to the next whole number. The Share Consolidation affected all shareholders uniformly and did not alter any shareholder's percentage interest in the Company's outstanding ordinary shares, except for adjustments that may result from the treatment of fractional shares. As such, all share and per share amounts have been given retroactive effect in the financial statements for all periods presented.

Net cash provided by financing activities was $5,807,166 and $1,648,171 for the years ended March 31, 2025 and 2024, respectively. Cash flows from financing activities for the year ended March 31, 2025 were primarily related to $754,511 in net proceeds received from an at-the-market transaction consisting of 391,017 shares at an average price of $1.9931, an exercise of warrants with a strike price of $2.934 exercised for gross proceeds of $786,735 where 268,144 ordinary shares were issued., and completing a registered direct offering of an aggregate of 1,108,892 ordinary shares, par value $0.001 per share of the Company at a price of $4.50 per share. In addition there was $107,756 in lease payments.

The Company has an accumulated deficit of $24,589,244 at March 31, 2025. We have not generated consistent cash flows to fund our operations yet and as of March 31, 2025, the Company had a cash balance of $4,228,944.

We plan to support our future research and development program, obtain product certification approvals in the territories we have identified, establish our distribution networks, and our general working capital and expenses requirements from our current cash balance. We may, however, over the longer term require additional capital to fund further research and development expenditures and commercialize our products.

At present, we have not generated any significant revenue from existing operations. Our continued existence is dependent on our current cash balance, the ability to obtain necessary financing to fund working capital, complete the planned product certification approvals in the territories we have identified and to establish our distribution networks. We do not expect to generate sufficient internal cash flows to finance these costs in the foreseeable future.

As noted above, the continuation of our current business plan requires us to raise significant additional capital. If we are unable to do so, we may have to curtail our business plans. We intend to use our current cash balance for primarily research and development program, obtaining product certification approvals in the territories we have identified, establishing our distribution networks and for general working capital and expenses purposes.

We will continually evaluate our business plans to determine the manner in which we can most effectively utilize our limited working capital resources. The timing of completion of all aspects of our business plan is highly dependent upon the availability of capital to implement each aspect of the business plan as well as other factors beyond our control.

If our future cash is insufficient to meet our requirements, we may further to seek government grants, to issue debt or equity securities or obtain additional credit facilities. To the extent additional funding is not achieved this could adversely affect our future business prospects and our ability to continue as a going concern.

C. Research and development, patents and licenses, etc.

For information concerning our research and development policies for the last two years and a description of the amount spent during the last two fiscal years on company-sponsored research and development activities, see “Item 5. Operating and Financial Review and Prospects— Results of Operation.”

D. Trend information.

We are a development stage company and it is not possible for us to predict with any degree of accuracy the outcome of our research, development or commercialization efforts. As such, it is not possible for us to predict with any degree of accuracy any known trends, uncertainties, demands, commitments or events that are reasonably likely to have a material effect on our net sales or revenues, income from continuing operations, profitability, liquidity or capital resources, or that would cause reported financial information to not necessarily be indicative of future operating results or financial conditions. However, to the extent possible, certain trends, uncertainties, demands, commitments and events are in this “Operating and Financial Review and Prospects.”

E. Critical Accounting Estimates

We prepare our financial statements in accordance with IFRS. In doing so, we must make estimates and assumptions that affect our reported amounts of assets, liabilities and expenses, as well as related disclosure of contingent assets and liabilities. In some cases, we could reasonably have used different accounting policies and estimates. Changes in the accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ materially from our estimates. To the extent that there are material differences between these estimates and actual results, our financial condition or results of operations will be affected. Significant

estimates include, but are not limited to, those related to leases, fixed asset lives, depreciation, intangible asset impairment, estimates relating to the valuation of warrants and stock-based compensation. For the Company's significant accounting policies, please see Note 2 to our audited consolidated financial statements of this annual report. We believe that our accounting policies contained therein are critical in fully understanding and evaluating our financial condition and operating results.

Mr. Norton received a master of business administration’s degree from Northwestern University and a bachelor’s degree in business administration in finance from Texas A&M University in 1996 and 2002, respectively. We believe Mr. Norton’s extensive experience qualifies him to serve as our independent director.

Equity Incentive Plans

Our Board and shareholders adopted a 2022 Equity Incentive Plan, a 2023 Equity Incentive Plan, and a 2024 Equity Incentive Plan to provide additional means through the grant of awards to attract, motivate, retain and reward selected key employees and other eligible persons.

On January 30, 2025, the Company filed a Form S-8 to register a total of 631,941 ordinary shares, par value $0.001 per share which included 250,000 ordinary shares issuable under the 2024 Equity Incentive Plan, 250,000 ordinary shares issuable under the 2023 Equity Incentive Plan, and 131,941 ordinary shares issuable under the 2022 Equity Incentive Plan.

Below is a summary of the equity incentive plans terms:

Shares Subject to the equity incentive plans

A total of 18,025 of our ordinary shares are available for issuance under the 2022 Equity Incentive Plan, a total of 20,584 of our ordinary shares are available for issuance under the 2023 Equity Incentive Plan and a total of 176,000 of our ordinary shares are available for issuance under the 2024 Equity Incentive Plan. If an award granted under each equity incentive plan is forfeited, canceled, settled, or otherwise terminated without a distribution of ordinary shares, the ordinary shares underlying that award will again become available for issuance under the equity incentive plan. If ordinary shares delivered under each equity incentive plan are tendered or withheld to pay the exercise price of a share option or to satisfy withholding taxes, those ordinary shares will also again become available for issuance under either of the equity incentive plans.

Administration of the equity incentive plans

Our Board or a committee appointed by the Board will administer the equity incentive plans. The plan administrator will have broad authority to:

Participation

Employees, directors and consultants that provide services to us or one of our subsidiaries may be selected to receive awards under the equity incentive plans.

Types of Awards

The equity incentive plans permit the granting of awards in the form of share options, performance awards, or other awards.

Share Options

A share option entitles the recipient to purchase ordinary shares at a fixed exercise price. The exercise price per share will be determined by the plan administrator in the applicable award agreement in its sole discretion at the time of the grant, but the exercise price cannot be less than the closing sales price for our ordinary shares on the grant date. The exercise price can be paid in cash, check, or by cashless or net exercise. The maximum term of each share option shall be fixed by the plan administrator, but in no event shall an option be exercisable more than ten (10) years after the date such option is granted.

Performance Awards

A performance award is an award that may vest contingent upon the attainment during a performance period of certain performance goals and which is granted under the terms and conditions of other awards pursuant to such terms and conditions established by the plan administrator.

Equitable Adjustments

In the event of a merger, consolidation, recapitalization, share split, reverse share split, reorganization, split-up, spin-off, combination, repurchase, or other change in corporate structure affecting the ordinary shares, the maximum number and kind of shares reserved for issuance or with respect to which awards may be granted under the equity incentive plan will be adjusted to reflect such event, and the plan administrator will make such adjustments as it deems appropriate and equitable in the number, kind and exercise price of ordinary shares covered by outstanding awards made under the equity incentive plan.

Change in Control

In the event of any proposed change in control (as defined in the equity incentive plans), the plan administrator will take any action as it deems appropriate, which action may include, without limitation, the following: (i) the continuation of any award, if the company is the surviving corporation; (ii) the assumption of any award by the surviving corporation or its parent or subsidiary; (iii) the substitution by the surviving corporation or its parent or subsidiary of equivalent awards; (iv) accelerated vesting of the award, with all performance objectives and other vesting criteria deemed achieved at targeted levels, and a limited period during which to exercise the award prior to closing of the change in control, or (v) cash settlement equal to the fair market value of the shares that would otherwise be issued to the recipient.

Term

The equity incentive plans will become effective when adopted by the Board and, unless terminated, the equity incentive plans will continue in effect for a term of ten (10) years.

Amendment and Termination

The Board may at any time amend, alter, suspend or terminate the equity incentive plan, although no such action may, without the written consent of the participant, impair the rights of any participant with respect to outstanding awards.

Status

Total equity awards outstanding under the 2022 Equity Incentive Plan are 113,916, total awards outstanding under the 2023 Equity Incentive Plan are 229,416 and total equity awards outstanding under the 2024 Equity Incentive Plan are 74,000 as of March 31, 2025.

C. Board Practices

Composition of our Board of Directors

Our board of directors consists of five directors. A director is not required to hold any shares in our company to qualify to serve as a director. The Corporate Governance Rules of the Nasdaq generally require that a majority of an issuer’s board of directors must consist of independent directors.

Our board of directors currently consists of five directors. Our board of directors has determined that each of Mr. Erez, Mr. Norton, and Mr. Haight is an “independent director” as defined under the Nasdaq rules. Our board of directors is composed of a majority of independent directors.

A director is not required to hold any of our shares to qualify to serve as a director.

Committees of the Board of Directors

We have established an audit committee, a compensation committee and a nominating and corporate governance committee under our Board of Directors. We have adopted a charter for each of the three committees. Each committee’s members and functions are described below.

Audit Committee.

Our audit committee consists of our three independent directors and is chaired by Mr. Haight. We have determined that satisfy the requirements of Section 303A of the Corporate Governance Rules/ Rule 5605(c)(2) of the Listing Rules of the NASDAQ and meet the

independence standards under Rule 10A-3 under the Securities Exchange Act of 1934, as amended. We have determined that qualifies as an “audit committee financial expert.” The audit committee oversees our accounting and financial reporting processes and the audits of the financial statements of our company. The audit committee is responsible for, among other things:

Compensation Committee.

Our compensation committee consists of our three independent directors and is chaired by Mr. Erez. We have determined that satisfy the “independence” requirements of Rule5605(c)(2) of the Listing Rules of the NASDAQ. The compensation committee assists the board in reviewing and approving the compensation structure, including all forms of compensation, relating to our directors and executive officers. Our chief executive officer may not be present at any committee meeting during which their compensation is deliberated upon. The compensation committee is responsible for, among other things:

Nominating and Corporate Governance Committee.

Our nominating and corporate governance committee consists of our three independent directors, and is chaired by Mr. Norton. We have determined that satisfy the “independence” requirements of Rule5605(c)(2) of the Listing Rules of the NASDAQ. The nominating and corporate governance committee assists the board in selecting individuals qualified to become our directors and in determining the composition of the board and its committees. The nominating and corporate governance committee is responsible for, among other things:

Code of Business Conduct and Ethics

We have adopted a code of business conduct and ethics, which is applicable to all of our directors, executive officers and employees and is publicly available.

Duties of Directors

Under Cayman Islands law, our board of directors has the powers necessary for managing, and for directing and supervising, our business affairs. The functions and powers of our board of directors include, among others:

Under Cayman Islands law, directors owe the following fiduciary duties: (i) duty to act in good faith in what the director believes to be in the best interests of the company as a whole; (ii) duty to exercise powers for the purposes for which those powers were conferred and not for a collateral purpose; (iii) directors should not improperly fetter the exercise of future discretion; (iv) duty not to put themselves in a position in which there is a conflict between their duty to the company and their personal interests; and (v) duty to exercise independent judgment. In addition to the above, directors also owe a duty to act with skill, care and diligence. This duty has been defined as a requirement to act as a reasonably diligent person having both the general knowledge, skill and experience that may reasonably be expected of a person carrying out the same functions as are carried out by that director in relation to the company and the general knowledge skill and experience which that director has.

As set out above, directors have a duty not to put themselves in a position of conflict and this includes a duty not to engage in self-dealing, or to otherwise benefit as a result of their position. However, in some instances what would otherwise be a breach of this duty can be forgiven and/or authorized in advance by the shareholders provided that there is full disclosure by the directors. This can be done by way of permission granted in the memorandum and articles of association or alternatively by shareholder approval at general meetings.

D. Employees

As of March 31, 2025, we had 19 full-time employees. There were 14 employees in the United Kingdom, 2 employee in the United States, and 3 employees in China.

E. Share Ownership

Item 7. Major Shareholders and Related Party Transactions

A. Major Shareholders

The following table presents information, as of the date of this report, regarding the beneficial ownership of our ordinary shares by:

The number of ordinary shares beneficially owned by each entity, person, and member of our board of directors or members of our executive management is determined in accordance with the rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under such rules, beneficial ownership includes any ordinary shares over which the individual has sole or shared voting power or investment power as well as any ordinary shares that the individual has the right to acquire within 60 days of the date of this report through the exercise of any option, warrant or other right. Except as otherwise indicated, and subject to applicable community property laws, the persons named in the table have sole voting and investment power with respect to all ordinary shares held by that person.

The percentage of outstanding ordinary shares is computed on the basis of 4,341,956 ordinary shares outstanding as of the date of this report. Ordinary shares that a person has the right to acquire within 60 days of the date of this report are deemed outstanding for purposes of computing the percentage ownership of the person holding such rights but are not deemed outstanding for purposes of computing the percentage ownership of any other person, except with respect to the percentage ownership of all members of our board of directors or executive management as a group. None of our shareholders has different voting rights from other shareholders. We are not aware of any arrangement that may, at a subsequent date, result in a change of control of our company.

Our authorized share capital is US$50,000 divided into 50,000,000 ordinary shares of $0.001 par value each.

We have included summaries of certain material provisions of our second amended and restated memorandum and articles of association (the Memorandum and Articles, respectively) and the Cayman Companies Act insofar as they relate to the material terms of our share capital. The summaries do not purport to be complete and are qualified in their entirety by reference to our Memorandum and Articles, which is filed as Exhibit 1.1 to this annual report.

Ordinary shares

All of our outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary shares are issued in registered form. Our shareholders, whether or not they are non-residents of the Cayman Islands, may freely hold and transfer their ordinary shares in accordance with our Memorandum and Articles.

Dividends

The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. Our Articles provide that our board of directors may declare and pay dividends if justified by our financial position and permitted by law. Our articles of association also provides that, subject to the Cayman Companies Act, the Company may also by ordinary resolution declare dividends in accordance with the respective rights of the shareholders but no dividend shall exceed the amount recommended by the directors.

Voting Rights

Holders of our ordinary shares vote on all matters submitted to a vote of our shareholders, except as may otherwise be required by law. In respect of matters requiring shareholders’ vote, each ordinary share is entitled to one vote. At any general meeting a resolution put to the vote of the meeting shall be decided on a show of hands unless voting by poll is duly demanded by the chairman of the meeting, by at least two shareholders having the right to vote on the resolutions, or by shareholder(s) together holding at least 10% of the total voting rights of all our shareholders having the right to vote at such general meeting. A quorum required for a meeting of shareholders consists of one or more shareholders who holds at least one-third of our issued voting shares. Shareholders’ meetings may be held annually. Each general meeting, other than an annual general meeting, shall be an extraordinary general meeting. Extraordinary general meetings may be called by a majority of our board of directors or upon a requisition of any one or more shareholders holding at the deposit of the requisition at least 10% of the aggregate share capital of our company that carries the right to vote at a general meeting, in which case on advance notice of at least 7 clear days is required for the convening of our annual general meeting and other general meetings by requisition of our shareholders.

Any ordinary resolution to be made by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast in a meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes attaching to the ordinary shares cast in a meeting.

A special resolution will be required for important matters such as amending our memorandum and articles of association or changing the name of the Company.

There are no limitations on non-residents or foreign shareholders in the memorandum and articles of association to hold or exercise voting rights on the ordinary shares imposed by foreign law or by the charter or other constituent document of our company. However, no person will be entitled to vote at any general meeting or at any separate meeting of the holders of the ordinary shares unless the person is registered as of the record date for such meeting and unless all calls or other sums presently payable by the person in respect of ordinary shares in the Company have been paid.

Winding Up; Liquidation

Subject to any special rights, privileges or restrictions as to the distribution of available surplus assets on liquidation applicable to any class or classes of shares (1) if we are wound up and the assets available for distribution among our shareholders are more than sufficient to repay the whole of the capital paid up at the commencement of the winding up, the excess shall be distributed pari passu among our shareholders in proportion to the amount paid up at the commencement of the winding up on the shares held by them, respectively, and (2) if we are wound up and the assets available for distribution among our shareholders as such are insufficient to repay the whole of the paid-up capital, those assets shall be distributed so that, as nearly as may be, the losses shall be borne by our shareholders in proportion to the capital paid up, or which ought to have been paid up, at the commencement of the winding up on the shares held by them, respectively.

Calls on ordinary shares and Forfeiture of ordinary shares

Our directors may from time to time make calls on our shareholders in respect of any moneys unpaid on their shares including any premium in a notice served to such shareholders at least 14 clear days prior to the specified time of payment. Any ordinary shares that have been called upon and remain unpaid are subject to forfeiture.

Redemption of ordinary shares

The Cayman Companies Act and our Memorandum and Articles permit us to purchase our own shares. In accordance with our Articles, provided the necessary shareholders or board approval have been obtained and requirements under the Cayman Companies Act have been satisfied, we may issue shares on terms that are subject to redemption at our option on such terms and in such manner as may be determined by our board of directors.

Inspection of Books and Records

Holders of our ordinary shares have no general right under our Articles to inspect or obtain copies of our list of shareholders or our corporate records. However, we will provide our shareholders with annual audited financial statements.

Issuance of Additional Shares

Our Memorandum and Articles authorize our board of directors to issue additional ordinary shares from time to time as our board of directors shall determine, to the extent of available authorized but unissued shares. Issuance of these shares may dilute the voting power of holders of ordinary shares.

Anti-Takeover Provisions

Some provisions of our Memorandum and Articles may discourage, delay or prevent a change of control of our company or management that shareholders may consider favorable. Our authorized, but unissued ordinary shares are available for future issuance without shareholders’ approval and could be utilized for a variety of corporate purposes, including future offerings to raise addition capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved ordinary shares could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Exempted Company

We are an exempted company with limited liability under the Cayman Companies Act. The Cayman Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except that an exempted company:

C. Material contracts.

We have not entered into any material contracts other than in the ordinary course of business and other than those described in “Item 4. Information on the Company” or elsewhere in this annual report on Form 20-F.

D. Exchange controls.

There are no government laws, decrees or regulations that restrict or that affect our export or import of capital or the remittance of dividends, interest or other payments to non-resident holders of our securities, including the availability of cash and cash equivalents for use by us and our wholly-owned subsidiary, except or otherwise as set forth under “Item 10. Additional Information—E. Taxation”

and “Item 3. Key Information Risk Factors – D. Risk Factors – Risks Related to Doing Business in China and Hong Kong - Restrictions on currency exchange may limit our ability to utilize our revenues effectively”.

E. Taxation.

The following discussion describes the material U.S. federal income tax consequences relating to the ownership and disposition of our ordinary shares by U.S. Holders (as defined below). This discussion applies to U.S. Holders that purchase our ordinary shares pursuant to the Company's IPO and hold such ordinary shares as capital assets. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended, U.S. Treasury regulations promulgated thereunder and administrative and judicial interpretations thereof, all as in effect on the date hereof and all of which are subject to change, possibly with retroactive effect. This discussion does not address all of the U.S. federal income tax consequences that may be relevant to specific U.S. Holders in light of their particular circumstances or to U.S. Holders subject to special treatment under U.S. federal income tax law (such as certain financial institutions, insurance companies, dealers or traders in securities or other persons that generally mark their securities to market for U.S. federal income tax purposes, tax-exempt entities or governmental organizations, retirement plans, regulated investment companies, real estate investment trusts, grantor trusts, brokers, dealers or traders in securities, commodities, currencies or notional principal contracts, certain former citizens or long-term residents of the United States, persons who hold our ordinary shares as part of a “straddle,” “hedge,” “conversion transaction,” “synthetic security” or integrated investment, persons that have a “functional currency” other than the U.S. dollar, persons that own directly, indirectly or through attribution 10% or more of the voting power of our ordinary shares, corporations that accumulate earnings to avoid U.S. federal income tax, partnerships and other pass-through entities, and investors in such pass-through entities). This discussion does not address any U.S. state or local or non-U.S. tax consequences or any U.S. federal estate, gift or alternative minimum tax consequences.

As used in this discussion, the term “U.S. Holder” means a beneficial owner of our ordinary shares who is, for U.S. federal income tax purposes, (i) an individual who is a citizen or resident of the United States, (ii) a corporation (or entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof, or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income tax regardless of its source or (iv) a trust (x) with respect to which a court within the United States is able to exercise primary supervision over its administration and one or more United States persons have the authority to control all of its substantial decisions or (y) that has elected under applicable U.S. Treasury regulations to be treated as a domestic trust for U.S. federal income tax purposes.

If an entity treated as a partnership for U.S. federal income tax purposes holds our ordinary shares, the U.S. federal income tax consequences relating to an investment in such ordinary shares will depend in part upon the status and activities of such entity and the particular partner. Any such entity should consult its own tax advisor regarding the U.S. federal income tax consequences applicable to it and its partners of the purchase, ownership and disposition of our ordinary shares.

Persons considering an investment in our ordinary shares should consult their own tax advisors as to the particular tax consequences applicable to them relating to the purchase, ownership and disposition of our ordinary shares including the applicability of U.S. federal, state and local tax laws and non-U.S. tax laws.

Passive Foreign Investment Company Consequences

In general, a corporation organized outside the United States will be treated as a PFIC for any taxable year in which either (i) at least 75% of its gross income is “passive income”, or the PFIC income test, or (ii) on average at least 50% of its assets, determined on a quarterly basis, are assets that produce passive income or are held for the production of passive income, or the PFIC asset test. Passive income for this purpose generally includes, among other things, dividends, interest, royalties, rents, and gains from the sale or exchange of property that gives rise to passive income. Assets that produce or are held for the production of passive income generally include cash, even if held as working capital or raised in a public offering, marketable securities, and other assets that may produce passive income. Generally, in determining whether a non-U.S. corporation is a PFIC, a proportionate share of the income and assets of each corporation in which it owns, directly or indirectly, at least a 25% interest (by value) is taken into account.

Although PFIC status is determined on an annual basis and generally cannot be determined until the end of a taxable year, based on the nature of our current and expected income and the current and expected value and composition of our assets, we do not presently expect to be a PFIC for our current taxable year or the foreseeable future. However, there can be no assurance given in this regard because the determination of whether we are or will become a PFIC is a fact-intensive inquiry made on an annual basis that depends, in part, upon the composition of our income and assets. In addition, there can be no assurance that the IRS will agree with our conclusion or that the IRS would not successfully challenge our position.

If we are a PFIC in any taxable year during which a U.S. Holder owns our ordinary shares, the U.S. Holder could be liable for additional taxes and interest charges under the “PFIC excess distribution regime” upon (i) a distribution paid during a taxable year that is greater than 125% of the average annual distributions paid in the three preceding taxable years, or, if shorter, the U.S. Holder’s holding period for our ordinary shares, and (ii) any gain recognized on a sale, exchange or other disposition, including a pledge, of our ordinary shares,

whether or not we continue to be a PFIC. Under the PFIC excess distribution regime, the tax on such distribution or gain would be determined by allocating the distribution or gain ratably over the U.S. Holder’s holding period for our ordinary shares. The amount allocated to the current taxable year (i.e., the year in which the distribution occurs or the gain is recognized) and any year prior to the first taxable year in which we are a PFIC will be taxed as ordinary income earned in the current taxable year. The amount allocated to other taxable years will be taxed at the highest marginal rates in effect for individuals or corporations, as applicable, to ordinary income for each such taxable year, and an interest charge, generally applicable to underpayments of tax, will be added to the tax.

If we are a PFIC for any year during which a U.S. Holder holds our ordinary shares, we must generally continue to be treated as a PFIC by that holder for all succeeding years during which the U.S. Holder holds such ordinary shares, unless we cease to meet the requirements for PFIC status and the U.S. Holder makes a “deemed sale” election with respect to our ordinary shares. If the election is made, the U.S. Holder will be deemed to sell our ordinary shares it holds at their fair market value on the last day of the last taxable year in which we qualified as a PFIC, and any gain recognized from such deemed sale would be taxed under the PFIC excess distribution regime. After the deemed sale election, the U.S. Holder’s ordinary shares would not be treated as shares of a PFIC unless we subsequently become a PFIC.

If we are a PFIC for any taxable year during which a U.S. Holder holds our ordinary shares and one of our non-United States subsidiaries is also a PFIC (i.e., a lower-tier PFIC), such U.S. Holder would be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC and would be taxed under the PFIC excess distribution regime on distributions by the lower-tier PFIC and on gain from the disposition of shares of the lower-tier PFIC even though such U.S. Holder would not receive the proceeds of those distributions or dispositions. Any of our non-United States subsidiaries that have elected to be disregarded as entities separate from us or as partnerships for U.S. federal income tax purposes would not be corporations under U.S. federal income tax law and accordingly, cannot be classified as lower-tier PFICs. However, non-United States subsidiaries that have not made the election may be classified as a lower-tier PFIC if we are a PFIC during your holding period and the subsidiary meets the PFIC income test or PFIC asset test. Each U.S. Holder is advised to consult its tax advisors regarding the application of the PFIC rules to any of our non-United States subsidiaries.

If we are a PFIC, a U.S. Holder will not be subject to tax under the PFIC excess distribution regime on distributions or gain recognized on our ordinary shares if a valid “mark-to-market” election is made by the U.S. Holder for our ordinary shares. An electing U.S. Holder generally would take into account as ordinary income each year, the excess of the fair market value of our ordinary shares held at the end of such taxable year over the adjusted tax basis of such ordinary shares. The U.S. Holder would also take into account, as an ordinary loss each year, the excess of the adjusted tax basis of such ordinary shares over their fair market value at the end of the taxable year, but only to the extent of the excess of amounts previously included in income over ordinary losses deducted as a result of the mark-to-market election. The U.S. Holder’s tax basis in our ordinary shares would be adjusted to reflect any income or loss recognized as a result of the mark-to-market election. Any gain from a sale, exchange or other disposition of our ordinary shares in any taxable year in which we are a PFIC would be treated as ordinary income and any loss from such sale, exchange or other disposition would be treated first as ordinary loss (to the extent of any net mark-to-market gains previously included in income) and thereafter as capital loss. If, after having been a PFIC for a taxable year, we cease to be classified as a PFIC because we no longer meet the PFIC income or PFIC asset test, the U.S. Holder would not be required to take into account any latent gain or loss in the manner described above and any gain or loss recognized on the sale or exchange of the ordinary shares would be classified as a capital gain or loss.

A mark-to-market election is available to a U.S. Holder only for “marketable stock.” Generally, stock will be considered marketable stock if it is “regularly traded” on a “qualified exchange” within the meaning of applicable U.S. Treasury regulations. A class of stock is regularly traded during any calendar year during which such class of stock is traded, other than in de minimis quantities, on at least fifteen (15) days during each calendar quarter.

Our ordinary shares will be marketable stock as long as they remain listed on the Nasdaq Capital Market and are regularly traded. A mark-to-market election will not apply to the ordinary shares for any taxable year during which we are not a PFIC, but will remain in effect with respect to any subsequent taxable year in which we become a PFIC. Such election will not apply to any of our non-U.S. subsidiaries. Accordingly, a U.S. Holder may continue to be subject to tax under the PFIC excess distribution regime with respect to any lower-tier PFICs notwithstanding the U.S. Holder’s mark-to-market election for the ordinary shares.

The Cayman Islands currently have no form of income, corporate or capital gains tax and no estate duty, inheritance tax or gift tax. There are currently no Cayman Islands’ taxes or duties of any nature on gains realized on a sale, exchange, conversion, transfer or redemption of the ordinary shares. Payments of dividends and capital in respect of the ordinary shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of interest and principal or a dividend or capital to any holder of the ordinary shares, nor will gains derived from the disposal of the ordinary shares be subject to Cayman Islands income or corporation tax as the Cayman Islands currently have no form of income or corporation taxes.

The tax consequences that would apply if we are a PFIC would also be different from those described above if a U.S. Holder were able to make a valid qualified electing fund, or QEF, election. As we do not expect to provide U.S. Holders with the information necessary for a U.S. Holder to make a QEF election, prospective investors should assume that a QEF election will not be available.

The U.S. federal income tax rules relating to PFICs are very complex. Prospective U.S. investors are strongly urged to consult their own tax advisors with respect to the impact of PFIC status on the purchase, ownership and disposition of our ordinary shares, the consequences to them of an investment in a PFIC, any elections available with respect to the ordinary shares and the IRS information reporting obligations with respect to the purchase, ownership and disposition of ordinary shares of a PFIC.

Distributions

Subject to the discussion above under “— Passive Foreign Investment Company Consequences,” a U.S. Holder that receives a distribution with respect to our ordinary shares generally will be required to include the gross amount of such distribution in gross income as a dividend when actually or constructively received to the extent of the U.S. Holder’s pro rata share of our current and/or accumulated earnings and profits (as determined under U.S. federal income tax principles). To the extent a distribution received by a U.S. Holder is not a dividend because it exceeds the U.S. Holder’s pro rata share of our current and accumulated earnings and profits, it will be treated first as a tax-free return of capital and reduce (but not below zero) the adjusted tax basis of the U.S. Holder’s ordinary shares. To the extent the distribution exceeds the adjusted tax basis of the U.S. Holder’s ordinary shares, the remainder will be taxed as capital gain. Because we may not account for our earnings and profits in accordance with U.S. federal income tax principles, U.S. Holders should expect all distributions to be reported to them as dividends.

Distributions on our ordinary shares that are treated as dividends generally will constitute income from sources outside the United States for foreign tax credit purposes and generally will constitute passive category income. Such dividends will not be eligible for the “dividends received’’ deduction generally allowed to corporate shareholders with respect to dividends received from U.S. corporations. Dividends paid by a “qualified foreign corporation’’ to certain non-corporate U.S. Holders may be are eligible for taxation at a reduced capital gains rate rather than the marginal tax rates generally applicable to ordinary income provided that a holding period requirement (more than sixty (60) days of ownership, without protection from the risk of loss, during the 121-day period beginning sixty (60) days before the ex-dividend date) and certain other requirements are met. Each U.S. Holder is advised to consult its tax advisors regarding the availability of the reduced tax rate on dividends to its particular circumstances. However, if we are a PFIC for the taxable year in which the dividend is paid or the preceding taxable year (see discussion above under “— Passive Foreign Investment Company Consequences’’), we will not be treated as a qualified foreign corporation, and therefore the reduced capital gains tax rate described above will not apply.

Dividends will be included in a U.S. Holder’s income on the date of the depositary’s receipt of the dividend. The amount of any dividend income paid in Cayman Islands dollars will be the U.S. dollar amount calculated by reference to the exchange rate in effect on the date of receipt, regardless of whether the payment is in fact converted into U.S. dollars. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder should not be required to recognize foreign currency gain or loss in respect to the dividend income. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt.

A non-United States corporation (other than a corporation that is classified as a PFIC for the taxable year in which the dividend is paid or the preceding taxable year) generally will be considered to be a qualified foreign corporation with respect to any dividend it pays on ordinary shares that are readily tradable on an established securities market in the United States.

Sale, Exchange or Other Disposition of Our ordinary shares

Subject to the discussion above under “— Passive Foreign Investment Company Consequences,’’ a U.S. Holder generally will recognize capital gain or loss for U.S. federal income tax purposes upon the sale, exchange or other disposition of our ordinary shares in an amount equal to the difference, if any, between the amount realized (i.e., the amount of cash plus the fair market value of any property received) on the sale, exchange or other disposition and such U.S. Holder’s adjusted tax basis in the ordinary shares. Such capital gain or loss generally will be long-term capital gain taxable at a reduced rate for non-corporate U.S. Holders or long-term capital loss if, on the date of sale, exchange or other disposition, the ordinary shares were held by the U.S. Holder for more than one year. Any capital gain of a non-corporate U.S. Holder that is not long-term capital gain is taxed at ordinary income rates. The deductibility of capital losses is subject to limitations. Any gain or loss recognized from the sale or other disposition of our ordinary shares will generally be gain or loss from sources within the United States for U.S. foreign tax credit purposes.

Medicare Tax

Certain U.S. Holders that are individuals, estates or trusts and whose income exceeds certain thresholds generally are subject to a 3.8% tax on all or a portion of their net investment income, which may include their gross dividend income and net gains from the disposition of our ordinary shares. If you are a United States person that is an individual, estate or trust, you are encouraged to consult your tax advisors regarding the applicability of this Medicare tax to your income and gains in respect of your investment in our ordinary shares.

Information Reporting and Backup Withholding

U.S. Holders may be required to file certain U.S. information reporting returns with the IRS with respect to an investment in our ordinary shares, including, among others, IRS Form 8938 (Statement of Specified Foreign Financial Assets). As described above under “Passive

Foreign Investment Company Consequences”, each U.S. Holder who is a shareholder of a PFIC must file an annual report containing certain information. U.S. Holders paying more than $100,000 for our ordinary shares may be required to file IRS Form 926 (Return by a U.S. Transferor of Property to a Foreign Corporation) reporting this payment. Substantial penalties may be imposed upon a U.S. Holder that fails to comply with the required information reporting.

Dividends on and proceeds from the sale or other disposition of our ordinary shares may be reported to the IRS unless the U.S. Holder establishes a basis for exemption. Backup withholding may apply to amounts subject to reporting if the holder (i) fails to provide an accurate U.S. taxpayer identification number or otherwise establish a basis for exemption, or (ii) is described in certain other categories of persons. However, U.S. Holders that are corporations generally are excluded from these information reporting and backup withholding tax rules.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a U.S. Holder’s U.S. federal income tax liability if the required information is furnished by the U.S. Holder on a timely basis to the IRS.

U.S. Holders should consult their own tax advisors regarding the backup withholding tax and information reporting rules.

YOU ARE URGED TO CONSULT ITS OWN TAX ADVISOR ABOUT THE TAX CONSEQUENCES TO IT OF AN INVESTMENT IN OUR ORDINARY SHARES IN LIGHT OF THE INVESTOR’S OWN CIRCUMSTANCES.

Prospective investors should consult their professional advisers on the possible tax consequences of buying, holding or selling any ordinary shares under the laws of their country of citizenship, residence or domicile.

The following is a discussion on certain Cayman Islands income tax consequences of an investment in the ordinary shares. The discussion is a general summary of present law, which is subject to prospective and retroactive change. It is not intended as tax advice, does not consider any investor’s particular circumstances, and does not consider tax consequences other than those arising under Cayman Islands law.

British Virgin Islands Taxation

There is no withholding tax, capital gains tax, capital transfer tax, estate duty, inheritance tax, succession tax or gift tax in the British Virgin Islands and any dividends, interest, rents, royalties, compensations and other amounts paid by our subsidiary in the British Virgin Islands are exempt from any taxation in the British Virgin Islands imposed under the British Virgin Islands Income Tax Ordinance (Cap 206) provided that they do not relate to real estate in the BVI.

Cayman Islands Taxation

The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or brought within the jurisdiction of the Cayman Islands. The Cayman Islands is a party to a double tax treaty entered with the United Kingdom in 2010 but is otherwise not party to any double tax treaties that are applicable to any payments made to or by our company. There are no foreign exchange controls or foreign exchange regulations or currency restrictions in the Cayman Islands.

Payments of dividends and capital in respect of our ordinary shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of our ordinary shares, as the case may be, nor will gains derived from the disposal of our ordinary shares be subject to Cayman Islands income or corporation tax.

The Cayman Islands enacted the International Tax Co-operation (Economic Substance) Act (Revised) together with the Guidance Notes published by the Cayman Islands Tax Information Authority from time to time. The Company is required to comply with the economic substance requirements from July 1, 2019 and make an annual report in the Cayman Islands as to whether or not it is carrying on any relevant activities and if it is, it must satisfy an economic substance test.

H. Documents on display.

We are subject to the information reporting requirements of the Exchange Act, applicable to foreign private issuers and under those requirements will file reports with the SEC. The SEC maintains an Internet website that contains reports and other information regarding issuers that file electronically with the SEC. You may read and copy this annual report, including the related exhibits and schedules, and any document we file with the SEC at http://www.sec.gov.

As a foreign private issuer, we are exempt from the rules under the Exchange Act related to the furnishing and content of proxy statements, and our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required under the Exchange Act to file annual, quarterly and current reports and financial statements with the SEC as frequently or as promptly as United States companies whose securities are registered under the Exchange Act. However, we file with the SEC, within four months after the end of each fiscal year, or such applicable time as required by the SEC, an annual report on Form 20-F containing financial statements audited by an independent registered public accounting firm, and submit to the SEC, on a Form 6-K, unaudited quarterly financial information for the first three quarters of each fiscal year within 60 days after the end of each such quarter, or such applicable time as required by the SEC.

We maintain a corporate website at www.viraxbiolabs.com. Information contained on, or that can be accessed through, our website does not constitute a part of this Annual Report on Form 20-F. We have included our website address in this Annual Report on Form 20-F solely as an inactive textual reference.

Item 11. Quantitative and Qualitative Disclosures About Market Risk.

Market risk is the risk of loss related to changes in market prices, including interest rates and foreign exchange rates, of financial instruments that may adversely impact our consolidated financial position, results of operations or cash flows.

Interest Rate Risk

We do not anticipate undertaking any significant long-term borrowings. At present, our investments consist primarily of cash and cash equivalents. We may invest in investment-grade marketable securities with maturities of up to three years, including commercial paper, money market funds, and government/non-government debt securities. The primary objective of our investment activities is to preserve principal while maximizing the income that we receive from our investments without significantly increasing risk and loss. Our investments are exposed to market risk due to fluctuation in interest rates, which may affect our interest income and the fair market value of our investments, if any. We manage this exposure by performing ongoing evaluations of our investments. Due to the short-term maturities, if any, of our investments to date, their carrying value has always approximated their fair value. If we decide to invest in investments other than cash and cash equivalents, it will be our policy to hold such investments to maturity in order to limit our exposure to interest rate fluctuations.

Foreign Currency Exchange Risk

Our foreign currency exposures give rise to market risk associated with exchange rate movements of the U.S dollar, our functional and reporting currency, mainly against the GBP and the Euro. Although the U.S dollar is our functional currency, a portion of our expenses are denominated in GBP, Renminbi and Euro and currently all of our revenues are denominated in dollars. We do not anticipate that a sizable portion of our expenses will be denominated in currencies other than the U.S dollar. To date, fluctuations in the exchange rates have not materially affected our results of operations or financial condition for the periods under review.

To date, we have not engaged in hedging transactions. In the future, we may enter into currency hedging transactions to decrease the risk of financial exposure from fluctuations in the exchange rates of our principal operating currencies. These measures, however, may not adequately protect us from the material adverse effects of such fluctuations.

The following “Use of Proceeds” information relates to the registration statement on Form F-1, as amended (File Number 333-263694) for our initial public offering, which was declared effective by the SEC on June 30, 2022. On July 25, 2022, the Company completed its IPO of 1,350,000 shares of common stock at a price to the public of $5.00 per share for $6.75 million.

On June 7, 2024, the Company received net proceeds of $754,511 from an At-the-Market Offering, pursuant to an At The Market Offering Agreement (the “Sales Agreement”) with H.C. Wainwright & Co., LLC (the “Sales Agent”), acting as the Company’s sales agent. In addition, the Company received $4,389,863 in net proceeds from a registered direct offering from the sale of 1,108,892 ordinary shares at a price of $4.50 per share. On August 19, 2024, 268,144 warrants with a strike price of $2.934 were exercised for gross proceeds of $786,736 and 268,144 ordinary shares were issued.

Item 15. Controls and Procedures.

Disclosure controls and procedures

Our management, including our chief executive officer, or CEO, and our chief financial officer, or CFO, are responsible for establishing and maintaining our disclosure controls and procedures (within the meaning of Rule 13a-15(e) of the Exchange Act). These controls and procedures were designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure. We evaluated these disclosure controls and procedures under the supervision of our CEO and CFO as of March 31, 2025. Based upon that evaluation, our management, including our CEO and CFO, concluded that our disclosure controls and procedures as of March 31, 2025 were not effective due to the control deficiency in internal control over financial reporting described below.

Management’s annual report on internal control over financial reporting

Disclosure controls and procedures (as defined in Exchange Act Rule 15d-15(e)) are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act, such as this report, is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures are also designed with the objective of ensuring that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Due to its inherent limitations, internal controls over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company has determined that it is too small to effectively assess our internal control over financial reporting as of March 31, 2025, based on the framework for Internal Control-Integrated Framework set forth by The Committee of Sponsoring Organizations of the Treadway Commission (COSO) (2013).

There has been no change in the Company’s internal control over financial reporting during the year ended March 31, 2025 that has materially affected, or is reasonably likely to materially affect, the company’s internal control over financial reporting. Management will continue to monitor and evaluate the effectiveness of our internal controls and procedures over financial reporting on an ongoing basis and are committed to taking further action and implementing additional improvements as necessary.
