This prospectus relates to the resale by the selling shareholders named in this prospectus from time to time of up to 11,453,062 of our ordinary shares, par value $0.0001 per share (the “Ordinary Shares”). These 11,453,062 Ordinary Shares consist of:

Among other things, (i) each Preferred Option is exercisable for $1.04077 per Ordinary Share and has a term of 5.5 years from the issuance date, (ii) each Pre-Funded Warrant is exercisable for $0.0001 per Ordinary Share and expires upon the exercise of the Pre-Funded Warrant, and (iii) each Placement Warrant is exercisable for $1.3010 per Ordinary Share and has a term of 5.5 years from the issuance date. The holder of the Pre-Funded Warrant may, in its sole discretion, elect to exercise the Pre-Funded Warrant through a cashless exercise, in which case the holder would receive upon such exercise the net number of Ordinary Shares determined according to the formula set forth in the Pre-Funded Warrant, as applicable. If the Company does not issue the Ordinary Shares in a timely fashion, the Preferred Options, the Pre-Funded Warrant, and the Placement Warrants each contain certain damages provisions. A holder will not have the right to exercise any portion of (i) the Preferred Options if the holder (together with its affiliates) would beneficially own in excess of 4.99% of the number of the Company’s Ordinary Shares outstanding immediately after giving effect to the exercise, (ii) the Pre-Funded Warrant if the holder (together with its affiliates) would beneficially own in excess of 9.99% of the number of the Company’s Ordinary Shares outstanding immediately after giving effect to the exercise, or (iii) the Placement Warrants if the holder (together with its affiliates) would beneficially own in excess of 4.99% of the number of the Company’s Ordinary Shares outstanding immediately after giving effect to the exercise, in each case as such percentage of beneficial ownership is determined in accordance with the terms of the Preferred Options and the Pre-Funded Warrants, as applicable. However, any holder may increase or decrease such percentage, but not in excess of 9.99%, provided that any increase will not be effective until the 61st day after such election. The exercise price of the Preferred Options and Placement Warrants is subject to appropriate adjustment in the event of certain share dividends and distributions, share splits, reclassifications or similar events

affecting our Ordinary Shares and also upon any distributions of assets, including cash, stock or other property to our shareholders. If a fundamental transaction occurs, then the successor entity will succeed to, and be substituted for us, and may exercise every right and power that we may exercise and will assume all of our obligations under the Preferred Options, Pre-Funded Warrants, and Placement Warratns with the same effect as if such successor entity had been named in the Preferred Options, the Pre-Funded Warrants, and PLacement Warrants itself.

Our registration of the Ordinary Shares covered by this prospectus does not mean that the selling shareholder will offer or sell any of such Ordinary Shares. The selling shareholders named in this prospectus, or their donees, pledgees, transferees or other successors-in-interest, may resell the Ordinary Shares covered by this prospectus through public or private transactions at prevailing market prices, at prices related to prevailing market prices or at privately negotiated prices. For additional information on the possible methods of sale that may be used by the selling shareholder, you should refer to the section of this prospectus entitled “Plan of Distribution.”

We will not receive any of the proceeds from the sale of Ordinary Shares by the selling shareholders. However, we will receive proceeds from the exercise of the Preferred Options, Pre-Funded Warrants, and Placement Warrants, if such securities are exercised for cash. We intend to use those proceeds, if any, for general corporate purposes.

Any Ordinary Shares subject to resale hereunder will have been issued by us and acquired by the selling shareholders prior to any resale of such shares pursuant to this prospectus.

No underwriter or other person has been engaged to facilitate the sale of the Ordinary Shares in this offering. We will bear all costs, expenses and fees in connection with the registration of the Ordinary Shares. The selling shareholders will bear all commissions and discounts, if any, attributable to their respective sales of our ordinary shares.

Investment in our Ordinary Shares involves a high degree of risk. See “Risk Factors” beginning on page 16, in our periodic reports filed from time to time with the Securities and Exchange Commission, which are incorporated by reference in this prospectus and in any applicable prospectus supplement. You should carefully read this prospectus and the accompanying prospectus supplement, together with the documents we incorporate by reference, before you invest in our ordinary shares.

We are both an “emerging growth company” and a “foreign private issuer” as defined under the U.S. federal securities laws and, as such, may elect to comply with certain reduced public company reporting requirements for this and future filings. See “Prospectus Summary — Implications of Being an Emerging Growth Company and a Foreign Private Issuer” for additional information. Investors are cautioned that you are buying shares of a shell company issuer incorporated in the Cayman Islands with operating subsidiaries in Singapore, China, Hong Kong and British Virgin Islands, investors will not hold direct equity investments in our China and Hong Kong operating subsidiaries. Our ordinary shares offered in this prospectus are shares of our Cayman Islands holding company.

Investing in our Ordinary Shares is highly speculative and involves a significant degree of risk. Virax Biolabs Group Limited, which we refer to as "Virax Cayman", 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 our own, Virax Cayman conduct a substantial majority of our sales and trading activities through our operating entity established in Singapore, Virax Biolabs Pte. Limited, which we refer to as SingaporeCo. Currently, Virax Cayman indirectly owns 95.65% of the equity interests in SingaporeCo. However, some of Virax Cayman’s operations are currently conducted through our operating entities established in the British Virgin Islands, Hong Kong and Shanghai, primarily, Logico Bioproducts Corp., Virax Immune T-Cell Medical Device Company Limited and Shanghai Xitu Consulting Co., Limited, which we refer to as Logico BVI, Virax Immune T-Cell and Shanghai Xitu, respectively. Our ordinary shares offered in this prospectus are shares of our Cayman Islands holding company.

Recent statements by the Chinese government have indicated an intent to exert more oversight and control over offerings that are conducted overseas and/or foreign investments in China based issuers. Any future action by the

Chinese government expanding the categories of industries and companies whose foreign securities offerings are subject to government review could significantly limit or completely hinder our ability to offer or continue to offer securities to investors and could cause the value of such securities to significantly decline or be worthless.

Recently, the PRC government initiated a series of regulatory actions and made a number of public statements on the regulation of business operations in China with little advance notice, including cracking down on illegal activities in the securities market, enhancing supervision over China-based companies listed overseas using a variable interest entity structure, adopting new measures to extend the scope of cybersecurity reviews, and expanding efforts in anti-monopoly enforcement. We are not subject to these regulatory actions or statements, as we do not have a variable interest entity structure and our business does not involve the collection of user data, implicate cybersecurity, or involve any other type of restricted industry. Because these statements and regulatory actions are new, however, it is highly uncertain how soon legislative or administrative regulation making bodies in China will respond to them, or what existing or new laws or regulations will be modified or promulgated, if any, or the potential impact such modified or new laws and regulations will have on our daily business operations or our ability to accept foreign investments and list on an U.S. exchange.

The Holding Foreign Companies Accountable Act, or the HFCA Act, was enacted on December 18, 2020. In accordance with the HFCA Act, trading in securities of any registrant on a national securities exchange or in the over-the-counter trading market in the United States may be prohibited if the Public Company Accounting Oversight Board (the “PCAOB”) determines that it cannot inspect or fully investigate the registrant’s auditor for three consecutive years beginning in 2021, and, as a result, an exchange may determine to delist the securities of such registrant. On June 22, 2021, the U.S. Senate passed the Accelerating Holding Foreign Companies Accountable Act, which, if enacted, would amend the HFCA Act and require the SEC to prohibit an issuer’s securities from trading on any U.S. stock exchanges if its auditor is not subject to PCAOB inspections for two consecutive years instead of three, thus reducing the time period before our securities may be prohibited from trading or delisted if our auditor is unable to meet the PCAOB inspection requirement. Pursuant to the HFCA Act, the PCAOB issued a Determination Report on December 16, 2021 which found that the PCAOB is unable to inspect or investigate completely registered public accounting firms headquartered in: (1) mainland China of the People’s Republic of China because of a position taken by one or more authorities in mainland China; and (2) Hong Kong, a Special Administrative Region and dependency of the PRC, because of a position taken by one or more authorities in Hong Kong. In addition, the PCAOB’s report identified the specific registered public accounting firms which are subject to these determinations. On August 26, 2022, the PCAOB entered into a Statement of Protocol with the China Securities Regulatory Commission and the Ministry of Finance of the PRC and, as summarized in the “Statement on Agreement Governing Inspections and Investigations of Audit Firms Based in China and Hong Kong” published on the U.S. Securities and Exchange Commission’s official website, the parties agreed to the following: (i) in accordance with the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, the PCAOB shall have independent discretion to select any issuer audits for inspection or investigation; (ii) the PCAOB shall have direct access to interview or take testimony from all personnel of the audit firms whose issuer engagements are being inspected or investigated; (iii) the PCAOB shall have the unfettered ability to transfer information to the SEC, in accordance with the Sarbanes-Oxley Act; and (iv) the PCAOB inspectors shall have access to complete audit work papers without any redactions, with view-only procedures for certain targeted pieces of information such as personally identifiable information. On December 15, 2022, the PCAOB Board determined that the PCAOB was able to secure complete access to inspect and investigate registered public accounting firms headquartered in mainland China and Hong Kong and voted to vacate its previous determinations to the contrary. However, whether the PCAOB will continue to be able to satisfactorily conduct inspections of PCAOB-registered public accounting firms headquartered in mainland China and Hong Kong is subject to uncertainty and depends on a number of factors out of our, and our auditor’s, control. The PCAOB is continuing to demand complete access in mainland China and Hong Kong moving forward and is already making plans to resume regular inspections in early 2023 and beyond, as well as to continue pursuing ongoing investigations and initiate new investigations as needed. In the future, if there is any regulatory change or step taken by PRC regulators that does not permit our auditor to provide audit documentations located in China or Hong Kong to the PCAOB for inspection or investigation, or the PCAOB expands the scope of the Determination so that we are subject to the HFCA Act, as the same may be amended, you may be deprived of the benefits of such inspection which could result in limitation or restriction to our access to the U.S. capital markets and trading of our securities, including trading on the national exchange and trading on “over-the-counter” markets, may be prohibited under the HFCA Act. On December 29, 2022, a legislation entitled “Consolidated Appropriations Act, 2023” (the “Consolidated Appropriations Act”), was signed into law by President Biden. The Consolidated Appropriations Act contained, among other things, reduces the number of consecutive non-inspection years required for triggering the prohibitions under the HFCA Act from three years to two. Our registered public accounting firm, BF Borgers CPA PC, is not headquartered in mainland China or Hong Kong and was not identified in this report as a firm subject to the PCAOB’s determination. Notwithstanding the foregoing, if the PCAOB is not able to fully conduct inspections of our auditor’s work papers in China, you may be deprived of the benefits of

such inspection which could result in limitation or restriction to our access to the U.S. capital markets and trading of our securities may be prohibited under the HFCA Act.

Within the organization, investor cash inflows have all been received by Virax Cayman. Cash to fund Virax Cayman’s operations is transferred from Virax Cayman down through our Singapore, Hong Kong, BVI entities and then into our Chinese entity through capital contributions and loans. However, the PRC government imposes controls on the convertibility of RMB into foreign currencies and, in certain cases, the remittance of currency out of China, and investment in Chinese companies, which are governed by the Foreign Investment Law and Company Law, and the dividends and distributions from Shanghai Xitu is subject to relevant regulations and restrictions on dividends and payment to parties outside of China. Transfers among our Singapore and Hong Kong entities are not restricted under Singapore and Hong Kong Laws. No dividends or distribution have been made by our subsidiaries or by Virax Cayman to date and we intend to reinvest all cash into our subsidiaries for the foreseeable future. For the years ended March 31, 2022 and 2021 and for the six months ended September 30, 2022, there was no transfer between Virax Cayman and its subsidiaries.

Virax Cayman 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 our own, Virax Cayman conducts our operations through its operating subsidiaries in Singapore, Hong Kong, China and British Virgin Islands and has been operating since 2013. Prior to the introduction of Virax branded products in 2020, the Group was engaged in the fast moving consumer goods (“FMCG”) importation business into Asia.

Virax Cayman is a global innovative biotechnology group that primarily engages in sales, distribution and marketing of diagnostics test kits and medical technology for the prevention, detection, diagnosis and risk management of viral diseases with a particular interest in the field of immunology. Our mission is to minimize the risks of viruses throughout the world via our products offerings.

Our product portfolio includes: (i) diagnostics test kits sold through our “ViraxClear” brand; and (ii) sourced brands of third party suppliers, independent of our own brands (“Sourced Brands”). Currently, our Group does not manufacture or develop any product that we sell in our product portfolio and we act as a distributor of third-party suppliers’ products. We expect to develop and launch an upcoming brand “Virax Immune”, with the intention of providing an immunology profiling platform that assesses each individual’s immune risk profile against major global viral diseases. We believe that the T-Cell in-vitro diagnostic (“IVD”) Tests and immunology platform we are developing under the Virax Immune brand will be particularly useful in the diagnosis and threat analysis of the major viruses faced globally. As of the date of the prospectus, we have developed a functioning prototype of our T-Cell IVD Test under the Virax Immune brand but we are still in the process of conducting further tests and we have not submitted any T-Cell IVD Test to any regulatory agency for approval. Currently, our clinical trials and research activities for our T-Cell IVD Test under the Virax Immune brand are conducted by independent third party science companies, namely ICON Clinical Research Limited and Charles River Laboratories, respectively, in the Netherlands and the United Kingdom. Prior to the sale of our T-Cell IVD Test under the Virax Immune brand in our targeted jurisdictions, namely, Canada, United Kingdom, the European Union and the United States, we must apply with the relevant authority for the regulatory approvals. In Canada, our T-Cell IVD Test will fall under Class I devices, which we will apply for the Health Canada Medical Device Establishment License. In the European Union, we intend to apply our T-Cell IVD Test under the self-certified Class A risk-based class route. Class A IVDs include specimen receptacles, laboratory instruments, and buffer solutions. Under the self-certified Class A risk-based class route, we do not require the involvement of a notified body to obtain the CE Marking to our T-Cell IVD Test. In the United Kingdom, as part of the transition due to the United Kingdom withdrawal from the European Union, we intend to use the recognized CE marks that we will apply with the European Union for our T-Cell IVD Test until June 30, 2023 (the “Transitional Arrangement”), after which, we will to conform with the UK IVD regime rather than relying on Transitional Arrangement and apply with the UK Medicine and Healthcare Products Regulatory Agency for a UK Conformity Assessed mark before we can sell our T-Cell IVD Test in the UK post June 30, 2023. In the United States, we intend to apply our T-Cell IVD Test under the Virax Immune brand under Class III devices (highest risk), which are subject to most of the requirements under Class I and Class II devices as well as to pre-market approval before they can be sold in the United States. For more detailed information on the Regulatory Approval on Medical Device Products with respect to our T-Cell IVD test under our Virax Immune brand, refer to “Regulations — Summary of Regulatory Approval on Medical Device Products (Relevant Jurisdictions).”

Currently, our Group does not develop or manufacture any product that we sell under the ViraxClear brand and Sourced Brands as we act as a distributor of third-party suppliers’ products. To facilitate the sales and distribution of our ViraxClear products, we predominately rely on our key third-party suppliers, Nanjing Vazyme Medical

Technology Co., Ltd in China for diagnostics test kits. After we receive our ViraxClear and Sourced Brands products from our suppliers, we utilize third party logistic companies for the distribution of our products to our end-users and strategic partners overseas. However, we believe our products, in particular diagnostic test kits, provide significant value for consumers, through improved detection of diseases, improvements in health, wellness and productivity as well as by reducing other healthcare costs, such as emergency visits and hospitalizations. Our Group also seeks to maximize consumers’ access to our products and services through competitive pricing and regular evaluations of our pricing arrangements and contracts with our distributors.

Historically, the end-users of our distribution partners under our ViraxClear brand and Sourced Brands include but not limited to, clinics, pharmacies, laboratories, hospitals, and other relevant groups on an international basis, covering 4 regions, including but not limited to Europe, South America, Asia Pacific, and Sub-Saharan Africa, and Our Group expects to extend our geographical reach to North America in 2023.

Currently, as stated above, clinical trials and research activities for our T-Cell IVD Test under the upcoming Virax Immune brand are conducted by independent third party science companies in the Netherlands and United Kingdom together with our United Kingdom subsidiary, Virax Biolabs (UK) Limited. As our Group does not manufacture or develop any product that we sell under the ViraxClear brand and Sourced Brands because we act as a distributor of third-party suppliers’ products, the trading and sales of these products are primarily conducted through our SingaporeCo with some trading and sales of these products through our Logico BVI which are located in Singapore and British Virgin Islands, respectively. Shanghai Xitu is located in the PRC and is primarily engaged in procurement. Further, 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; Mr. Jason Davis, our Chief Financial Officer, is located in the United States and holds a United States passport; Mr. Mark Ternouth, our Chief Technical Officer, holds a British Passport and currently resides in Shanghai, China; Mr. Tomasz George, our Chief Scientific Officer, holds a British passport and currently resides in the United Kingdom; Mr. Cameron Shaw, our Chief Operating Officer and director, holds a British passport and currently resides in the Malta; 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 the United States.

The Regulations on Mergers and Acquisitions of Domestic Companies by Foreign Investors, or the M&A Rules, adopted by six PRC regulatory agencies in 2006 and amended in 2009, require an overseas special purpose vehicle formed for listing purposes through acquisitions of PRC domestic companies and controlled by PRC companies or individuals to obtain the approval of the CSRC and Ministry of Commerce of the PRC (“MOFCOM”), prior to the listing and trading of such special purpose vehicle’s securities on an overseas stock exchange. Substantial uncertainty remains regarding the scope and applicability of the M&A Rules

to offshore special purpose vehicles. As of the closing date of the PIPE Offering, that CSRC’s approval under the M&A Rules is not required for the listing and trading of our Ordinary Shares on Nasdaq in the context of this offering given that we are an exempted company with limited liability incorporated under the laws of the Cayman Islands with some operations located in Hong Kong and the PRC controlled by non-PRC citizens. As such, we do not fit into the definition of “overseas special purpose vehicle” under the M&A Regulations and we have never conducted any merger or acquisitions of any PRC domestic companies with a related party relationship. MOFCOM’s approval under the M&A Rules is also not required as we have never conducted any merger or acquisitions of any PRC domestic companies with a related party relationship. We cannot assure you that relevant PRC governmental agencies, including the CSRC, would reach the same conclusion as we do. If we or our subsidiaries inadvertently conclude that such approval is not required, our ability to offer or continue to offer our Ordinary Shares to investors could be significantly limited or completed hindered, which could cause the value of our Ordinary Shares to significantly decline or become worthless. Our Group or Shanghai Xitu may also face sanctions by the CSRC, the CAC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties on our operations in China, limit our ability to pay dividends outside of China, limit our operations in China, delay or restrict the repatriation of the proceeds from this offering into China or take other actions that could have a material adverse effect on our business, financial condition, results of operations and prospects, as well as the trading price of our securities.

On July 6, 2021, the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council jointly issued the Opinions on Strictly Cracking Down on Illegal Securities Activities According to Law (the “Opinions”), which called for strengthened regulation over illegal securities activities and supervision on overseas listings by China-based companies and propose to take effective measures.

As of the closing date of the PIPE Offering, no official guidance or related implementation rules have been issued in relation to the Opinions, and the interpretation and implementation of the Opinions also remain unclear to some extent at this stage. Based on our understanding of the current PRC laws and regulations in effect at the time of this prospectus, no prior permission is required under the M&A Rules or the Opinions from any PRC governmental authorities (including the CSRC) for consummating this offering by our company. However, there can be no assurance that the relevant PRC governmental authorities, including the CSRC, would reach the same conclusion as us, or that the CSRC or any other PRC governmental authorities would not promulgate new rules or new interpretation of current rules (with retrospective effect) to require us to obtain CSRC or other PRC governmental approvals for this offering. If we or our subsidiaries inadvertently conclude that such permission is not required, our ability to offer or continue to offer our Ordinary Shares to investors could be significantly limited or completed hindered, which could cause the value of our Ordinary Shares to significantly decline or become worthless. Our Group or Shanghai Xitu may also face sanctions by the CSRC, the CAC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties on our operations in China, limit our ability to pay dividends outside of China, limit our operations in China, delay or restrict the repatriation of the proceeds from this offering into China or take other actions that could have a material adverse effect on our business, financial condition, results of operations and prospects, as well as the trading price of our securities.

On December 28, 2021, the Cyberspace Administration of China (the “CAC”), published the Measures for Cybersecurity Review which became effective on February 15, 2022, which required that any “network platform operator” controlling personal information of no less than one million users which seeks to list on a foreign stock exchange should also be subject to cybersecurity review. The PRC Data Security Law, which took effect on September 1, 2021, imposes data security and privacy obligations on entities and individuals that carry out data activities, provides for a national security review procedure for data activities that may affect national security and imposes export restrictions on certain data and information. On August 20, 2021, the Standing Committee of the People’s Congress promulgated the PRC Personal Information Protection Law (the “PIPL”), which took effect on November 1, 2021. The PIPL sets out the regulatory framework for handling and protection of personal information and transmission of personal information to overseas. Shanghai Xitu is not a network platform operator, nor do we conduct data activities that may affect national security or hold personal information of more than one million users. In addition, we do not conduct any cross border transfer of personal information from the PRC to other jurisdictions. As such, we do not believe the Virax Group falls in the “operators of critical information infrastructure” as mentioned above and we are not subject to PRC cybersecurity review. However, the Measures for Cybersecurity Review (2021 version), the Data Security Law and the PIPL were recently adopted and remain unclear on how they will be interpreted, amended and implemented by the relevant PRC governmental authorities.

The CSRC promulgated Trial Administrative Measures of the Overseas Securities Offering and Listing by Domestic Companies (the “Overseas Listing Trial Measures”) and five relevant guidelines on February 17, 2023, which will become effective on March 31, 2023. The Overseas Listing Trial Measures regulate both direct and indirect overseas offering and listing by PRC domestic company by adopting a filing-based regulatory regime. The Overseas Listing Trial Measures also provide that if the issuer both meets the following criteria, the overseas securities offering and listing conducted by such issuer will be deemed as indirect overseas offering subject to the filing procedure set forth under the Overseas Listing Trial Measures: (i) 50% or more of the issuer’s operating revenue, total profit, total assets or net assets as documented in its audited consolidated financial statements for the most recent fiscal year is accounted for by domestic companies; and (ii) the issuer’s business activities are substantially conducted in mainland China, or its principal place of business are located in mainland China, or the senior managers in charge of its business operations and management are mostly Chinese citizens or domiciled in Mainland China. Where an issuer submits an application for an initial public offering to competent overseas regulators, such issuer must file with the CSRC within three business days after such application is submitted. The Overseas Listing Trial Measures also require subsequent reports to be filed with the CSRC on material events, such as change of control or voluntary or forced delisting of the issuer who have completed overseas offerings and listings.

Pursuant to the Overseas Listing Trial Measures, domestic enterprises that directly or indirectly offer or list securities on an overseas stock exchange shall file with the CSRC. We are not “directly” offering securities overseas (as Shanghai Xitu is not the issuer of the listed securities on an overseas stock exchange). According to the Overseas Listing Trial Measures, if the issuer meets the following conditions, it shall be deemed as an “indirect” overseas offering and listing of a domestic enterprise: (i) 50% or more of the issuer’s operating revenue, total profit, total assets or net assets as documented in its audited consolidated financial statements for the most recent fiscal year is accounted for by domestic companies; and (ii) the issuer’s business activities are substantially conducted in mainland China, or its principal place of business are located in mainland China, or the senior managers in charge of its business operations and management are mostly Chinese citizens or domiciled in Mainland China

Based on the above mentioned, given that the operating income, total profit, total assets or net assets of the Shanghai Xitu for the last financial year accounted for less than 50% of the Virax Group’s audited consolidated financial statements and none of Shanghai Xitu’s senior management personnel is a PRC Citizen and only two (2) out of seven (7) have an ordinary residence located in the PRC, this offering shall not be deemed as a domestic enterprise that indirectly offer or list securities on an overseas stock exchange, nor does it requires filing or approvals from the CSRC. However, there can be no assurance that the relevant PRC governmental authorities, including the CSRC, would reach the same conclusion as us, or that the CSRC or any other PRC governmental authorities would not promulgate new rules or new interpretation of current rules (with retrospective effect) to require us to obtain CSRC or other PRC governmental approvals for this offering. If we or our subsidiaries inadvertently conclude that such approvals are not required, our ability to offer or continue to offer our Ordinary Shares to investors could be significantly limited or completed hindered, which could cause the value of our Ordinary Shares to significantly decline or become worthless. Our Group or Shanghai Xitu may also face sanctions by the CSRC, the CAC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties on our operations in China, limit our ability to pay dividends outside of China, limit our operations in China, delay or restrict the repatriation of the proceeds from this offering into China or take other actions that could have a material adverse effect on our business, financial condition, results of operations and prospects, as well as the trading price of our securities.

We have been closely monitoring regulatory developments in China regarding any necessary approvals from the CSRC or other PRC governmental authorities required for overseas listings, including this offering. Our business may be subject to various government regulations and regulatory interference. As of the date of this prospectus, (i) Shanghai Xitu has obtained all necessary permissions or approvals and authorizations in the PRC in all material aspects in relation to conducting its business operations in China; and (ii) we are not required to obtain any permission or approval from any PRC authority to issue securities to foreign investors (by Virax Cayman) or in connection with this offering under PRC laws or regulations in effect. Except for the business license issued by the local branch of the State Administration for Market Regulation, which Shanghai Xitu’s have obtained and are in full force and effect as of the date of this prospectus, Shanghai Xitu is not required to obtain any other licenses, approvals or permits to conduct its business operations in China. To the best of our knowledge, as of the date of this prospectus, there are no laws or regulations that are or will be adopted in the near future by PRC government authorities that would prevent Shanghai Xitu from maintaining the business license it has obtained or would require it to obtain additional licenses or qualifications in order to operate its current business operations. Further, there are no PRC laws and regulations (including the CSRC, the CAC, or any other government entity) in force explicitly requiring that our Group or

Shanghai Xitu to obtain permission from PRC authorities for this offering or to issue securities to foreign investors (by Virax Cayman) and we are not required to obtain additional permission or approval from Chinese authorities, including the CSRC and the CAC, to either approve our PRC subsidiaries’ operation or to offer the securities (of Virax Cayman) being registered to foreign investors. Nevertheless, we may incur increased costs necessary to comply with existing and newly adopted laws and regulations or penalties for any failure to comply. Furthermore, given recent statements by the Chinese government indicating an intent to exert more oversight and control over offerings that are conducted overseas, although as of the date of this prospectus, our Group or Shanghai Xitu have not been involved in any investigations initiated by the applicable governmental regulatory authorities, nor have we received any inquiry, notice, warning, or sanction in such respect, there remains uncertainty as to the enactment, interpretation and implementation of regulatory requirements related to overseas securities offerings and other capital markets activities. If it is determined in the future that the approval of the CSRC, the CAC or any other regulatory authority is required for this offering, our Group or Shanghai Xitu may face sanctions by the CSRC, the CAC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties on our operations in China, limit our ability to pay dividends outside of China, limit our operations in China, delay or restrict the repatriation of the proceeds from the PIPE Offering into China or take other actions that could have a material adverse effect on our business, financial condition, results of operations and prospects, as well as the trading price of our securities. Consequently, if you engage in market trading or other activities in anticipation of and prior to settlement and delivery of the Ordinary Shares that we are offering, you do so at the risk that settlement and delivery may not occur. In addition, if the CSRC, the CAC or other regulatory PRC agencies later promulgate new rules requiring that our Group or Shanghai Xitu obtain their approvals for this PIPE Offering, our Group or Shanghai Xitu may be unable to obtain a waiver of such approval requirements, if and when procedures are established to obtain such a waiver. Any uncertainties and/or negative publicity regarding such an approval requirement could have a material adverse effect on our ability to complete this offering or any follow-on offering of our securities or the market for and market price of our ordinary shares, significantly limit or completely hinder our ability to offer or continue to offer securities to investors, or cause such securities to significantly decline in value or become worthless.

Currently, Virax Cayman is incorporated in Cayman Islands to be the ultimate parent company of the Group. As a holding company with no material operations of our own, Virax Cayman conduct our operations through our operating subsidiaries established in Singapore, Hong Kong, China, and the British Virgin Islands. Currently, Virax Cayman indirectly owns 95.65% of the equity interests in SingaporeCo. However, some of our operations are currently conducted through our operating entities established in Hong Kong and Shanghai, primarily, Virax Immune T-Cell Medical Device Company Limited and Shanghai Xitu Consulting Co., Limited, which we refer to as Virax Immune T-Cell and Shanghai Xitu, respectively. Virax Cayman is permitted under the laws of Cayman Islands to provide funding to our subsidiaries in Singapore, British Virgin Islands, Hong Kong and Shanghai through loans or capital contributions on the amount of the funds. Virax Cayman can distribute earnings from its businesses, including subsidiaries, to the U.S. investors as well as the ability to settle amounts owed under intercompany agreements. Our operations in Singapore, British Virgin Islands, Hong Kong and Shanghai were in loss position since 2020, and the Group has raised capital through financing transactions and provided funding to our operations.

Our operating subsidiaries are permitted under the laws of Singapore, British Virgin Islands, PRC and Hong Kong, respectively, to provide funding to Virax Cayman, the holding company incorporated in the Cayman Islands through dividend distributions. Our Group currently intend to retain all available funds and future earnings, if any, for the operation and expansion of our business and do not anticipate declaring or paying any dividends in the foreseeable future. We currently do not have any dividend policy, and we do not anticipate declaring or paying dividends in the foreseeable future. We intend to retain all available funds and any future earnings to fund the development and expansion of our business. If our subsidiaries incurs debt on its own behalf in the future, the instruments governing such debt may restrict their ability to pay dividends to us. As of the date of this prospectus, there have been cash flows between our subsidiaries, and cash flows between our Virax Cayman and our subsidiaries to fund operations in the normal course of business.

Currently, some of our operations are currently conducted through our operating entities established in Hong Kong and Shanghai. We did not have or intend to set up any subsidiary or enter into any contractual arrangements to establish a VIE structure with any entity in China. Since Hong Kong is a special administrative region of the PRC and the basic policies of the PRC regarding Hong Kong are reflected in the Basic Law, providing Hong Kong with a high degree of autonomy and executive, legislative and independent judicial powers, including that of final adjudication

under the principle of “one country, two systems”. Under Hong Kong law, dividends could only be paid out of distributable profits (that is, accumulated realized profits less accumulated realized losses) or other distributable reserves. Dividends cannot be paid out of share capital. Under the current practice of the Inland Revenue Department of Hong Kong, no tax is payable in Hong Kong in respect of dividends paid by us.

Further, the PRC government imposes controls on the convertibility of RMB into foreign currencies and, in certain cases, the remittance of currency out of China. The dividends and distributions from Shanghai Xitu is subject to relevant regulations and restrictions on dividends and payment to parties outside of China. Investment in Chinese companies, which are governed by the Foreign Investment Law and Company Law, and the dividends and distributions from Shanghai Xitu is subject to relevant regulations and restrictions on dividends and payment to parties outside of China. Applicable PRC law permits payment of dividends to Virax Cayman by Shanghai Xitu only out of its net income, if any, determined in accordance with PRC accounting standards and regulations. Shanghai Xitu is required to set aside a portion of its net income, if any, each year to fund general reserves for appropriations until such reserves have reached 50% of the relevant entity’s registered capital. These reserves are not distributable as cash dividends. A PRC company is not permitted to distribute any profits until any losses from prior fiscal years have been offset. Profits retained from prior fiscal years may be distributed together with distributable profits from the current fiscal year. In addition, registered share capital and capital reserve accounts are also restricted from withdrawal in the PRC, up to the amount of net assets held in each operating subsidiary.

Within the organization, investor cash inflows have all been received by Virax Cayman. Cash to fund Virax Cayman’s operations is transferred from Virax Cayman down through our Singapore, Hong Kong, BVI entities and then into our Chinese entity through capital contributions and loans. Transfers among our Singapore and Hong Kong entities are not restricted. Furthermore, subject to payment of withholding taxes, there are no restrictions and limitations on our ability to distribute earnings from our subsidiaries to Virax Cayman and U.S. investors as well as the ability to settle amounts owed under any agreements. No dividends or distribution have been made by our subsidiaries or by Virax Cayman to date and we intend to reinvest all cash into our subsidiaries for the foreseeable future. For the years ended March 31, 2022 and 2021 and for the six months ended September 30, 2022, there was no transfer of funds between Virax Cayman and its subsidiaries.

Further, subject to the Companies Act and our Second Amended and Restated Memorandum and Articles of Association, our board of directors may authorize and declare a dividend to shareholders from time to time out of the profits from Virax Cayman, realized or unrealized, or out of the share premium account, provided that Virax Cayman will remain solvent, meaning Virax Cayman is able to pay its debts as they come due in the ordinary course of business. There is no further Cayman Islands statutory restriction on the amount of funds which may be distributed by us in the form of dividends.

There are no restrictions or limitations under the laws of Singapore imposed on the conversion of Singapore dollars into foreign currencies and the remittance of currencies out of Singapore, nor is there any restriction on any foreign exchange to transfer cash between Virax Cayman and its subsidiaries, across borders and to foreign investors outside of Singapore, nor is there any restrictions and limitations to distribute earnings from the subsidiaries, to Virax Cayman and investors outside of Singapore and amounts owed as well as the ability to settle amounts owed under intercompany agreements. There are no foreign exchange controls in Singapore. For the years ended March 31, 2022 and 2021, and for the six months ended September 30, 2022, there was no transfer between Virax Cayman and its subsidiaries. As of the date of this prospectus and for the years ended March 31, 2022 and 2021, and for the six months ended September 30, 2022, we have not declared any dividend. If we determine to pay dividends on any of our Ordinary Shares in the future, as a holding company, we will be dependent on receipt of funds from our operating subsidiaries in Singapore, British Virgin Islands and Hong Kong. Under the current practice of the Inland Revenue Authority of Singapore, no tax is payable in Singapore, in respect of dividends paid by us, and under the current laws of the Cayman Islands, we are also not subject to tax on income or capital gains and withholding tax is not imposed upon payments of dividends from Virax Cayman to its shareholders. Under the current practice of the Inland Revenue Department of Hong Kong, no tax is payable in Hong Kong in respect of dividends paid by us. Further, we do not have specific cash management policies and procedures in place that dictate how funds are transferred through our organization, however, we have been closely monitoring our transfer of funds and will adopt relevant policies and procedures if necessary.

As a company with less than $1.235 billion in revenue during our last fiscal year, we qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act, or JOBS Act, enacted in April 2012, and may take advantage of reduced reporting requirements that are otherwise applicable to public companies. These provisions include, but are not limited to:

•

being permitted to present only two years of audited financial statements and only two years of related Management’s Discussion and Analysis of Financial Condition and Results of Operations in our filings with the SEC;

•

not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting;

•

reduced disclosure obligations regarding executive compensation in periodic reports, proxy statements and registration statements; and

•

exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

We may take advantage of these provisions until the last day of our fiscal year following the fifth anniversary of the date of the first sale of our Ordinary Shares pursuant to this offering. However, if certain events occur before the end of such five-year period, including if we become a “large accelerated filer,” our annual gross revenues exceed $1.235 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company before the end of such five-year period.

In addition, Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, or the Securities Act, for complying with new or revised accounting standards. We have elected to take advantage of the extended transition period for complying with new or revised accounting standards and acknowledge such election is irrevocable pursuant to Section 107 of the JOBS Act.

We are a “foreign private issuer,” as defined by the SEC. As a result, in accordance with the rules and regulations of The Nasdaq Stock Market LLC, or Nasdaq, we may comply with home country governance requirements and certain exemptions thereunder rather than complying with Nasdaq corporate governance standards. We may choose to take advantage of the following exemptions afforded to foreign private issuers:

•

Exemption from filing quarterly reports on Form 10-Q or provide current reports on Form 8-K disclosing significant events within four (4) days of their occurrence.

•

Exemption from Section 16 rules regarding sales of Ordinary Shares by insiders, which will provide less data in this regard than shareholders of U.S. companies that are subject to the Exchange Act.

•

Exemption from the Nasdaq rules applicable to domestic issuers requiring disclosure within four (4) business days of any determination to grant a waiver of the code of business conduct and ethics to directors and officers. Although we will require board approval of any such waiver, we may choose not to disclose the waiver in the manner set forth in the Nasdaq rules, as permitted by the foreign private issuer exemption.

•

Exemption from the requirement that our board of directors have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities.

•

Exemption from the requirements that director nominees are selected, or recommended for selection by our board of directors, either by (i) independent directors constituting a majority of our board of

directors’ independent directors in a vote in which only independent directors participate, or (ii) a committee comprised solely of independent directors, and that a formal written charter or board resolution, as applicable, addressing the nominations process is adopted.

Furthermore, Nasdaq Rule 5615(a)(3) provides that a foreign private issuer, such as us, may rely on our home country corporate governance practices in lieu of certain of the rules in the Nasdaq Rule 5600 Series and Rule 5250(d), provided that we nevertheless comply with Nasdaq’s Notification of Noncompliance requirement (Rule 5625), the Voting Rights requirement (Rule 5640) and that we have an audit committee that satisfies Rule 5605(c)(3), consisting of committee members that meet the independence requirements of Rule 5605(c)(2)(A)(ii). If we rely on our home country corporate governance practices in lieu of certain of the rules of Nasdaq, our shareholders may not have the same protections afforded to shareholders of companies that are subject to all of the corporate governance requirements of Nasdaq. If we choose to do so, we may utilize these exemptions for as long as we continue to qualify as a foreign private issuer.

Although we are permitted to follow certain corporate governance rules that conform to Cayman Islands requirements in lieu of many of the Nasdaq corporate governance rules, we intend to comply with the Nasdaq corporate governance rules applicable to foreign private issuers.

Investing in our securities involves a high degree of risk. In addition to the other information contained in this prospectus and in the documents we incorporate by reference herein, you should carefully consider the risks discussed below and under the heading “Risk Factors” in our Annual Report on Form 20-F for the fiscal year ended March 31, 2022 as well as any amendment or update to our risk factors reflected in subsequent filings with the SEC, before making a decision about investing in our securities. The risks and uncertainties discussed below and in the documents incorporated by reference are not the only ones facing us. Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also harm our business. If any of these risks occur, our business, financial condition and operating results could be harmed, the trading price of our ordinary shares could decline and you could lose part or all of your investment.

You may experience future dilution as a result of future equity offerings and other issuances of our securities.

In order to raise additional capital, we may in the future offer additional ordinary shares or other securities convertible into or exchangeable for our ordinary shares at prices that may not be the same as the price per share paid by the investors in this offering. We may not be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by the investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing shareholders. The price per share at which we sell additional ordinary shares or securities convertible into ordinary shares in future transactions may be higher or lower than the price per share paid to the selling shareholders. Our shareholders will incur dilution upon exercise of any outstanding stock options, warrants or other convertible securities or upon the issuance of ordinary shares under our share incentive programs.

We expect to require additional capital in the future in order to develop our product candidates, which are in early stages of development. If we do not obtain any such additional financing, it may be difficult to effectively realize our long-term strategic goals and objectives.

Our current cash resources will not be sufficient to fund the development of our product candidates through all of the required clinical trials to receive regulatory approval and commercialization. If we cannot secure this additional funding when such funds are required, we may fail to develop our product candidates or be forced to forego certain strategic opportunities.

Any additional capital raised through the sale of equity or equity-backed securities may dilute our shareholders’ ownership percentages and could also result in a decrease in the market value of our equity securities.

The terms of any securities issued by us in future capital transactions may be more favorable to new investors, and may include preferences, superior voting rights and the issuance of warrants or other derivative securities, which may have a further dilutive effect on the holders of any of our securities then outstanding.

In addition, we may incur substantial costs in pursuing future capital financing, including investment banking fees, legal fees, accounting fees, securities law compliance fees, printing and distribution expenses and other costs. We may also be required to recognize non-cash expenses in connection with certain securities we issue, such as convertible notes and warrants, which may adversely impact our financial condition.

Future sales of our ordinary shares could reduce the market price of our ordinary shares.

If we or our existing shareholders, our directors or their affiliates or certain of our executive officers, sell a substantial number of our ordinary shares in the public market, including the Resale Shares once issuable upon exercise of the Pre-Funded Warrant and Ordinary Warrants, the market price of our ordinary shares could decrease significantly. The perception in the public market that we or our shareholders might sell our Ordinary Shares could also depress the market price of our ordinary shares and could impair our future ability to obtain capital, especially through an offering of equity securities.

We have made significant offerings of our ordinary shares in the past and may do so again in the future.

The market price of our ordinary shares may be subject to fluctuation and you could lose all or part of your investment.

Our ordinary shares were first offered publicly in our IPO in July 2020 at a price of $5.00 per share, and our ordinary shares have subsequently traded as high as $20.86 per share and as low as $0.61 per share through March 15, 2023. The market price of our ordinary shares on the Nasdaq Capital Market may fluctuate as a result of a number of factors, some of which are beyond our control, including, but not limited to:

•

the introduction of new products or product enhancements by us or others in our industry;

•

disputes or other developments with respect to our or others’ intellectual property rights;

•

our ability to develop, obtain regulatory clearance or approval for, and market new and enhanced products on a timely basis;

•

quarterly variations in our results of operations or those of others in our industry;

•

general market conditions and other factors, including factors unrelated to our operating performance or the operating performance of our competitors.

These factors and any corresponding price fluctuations may materially and adversely affect the market price of our ordinary shares and result in substantial losses being incurred by our investors. In the past, following periods of market volatility, public company shareholders have often instituted securities class action litigation. If we were involved in securities litigation, it could impose a substantial cost upon us and divert the resources and attention of our management from our business.

All ordinary shares offered by this prospectus are being registered for the accounts of the selling shareholders and we will not receive any proceeds from the sale of these shares. However, we have received and we may receive proceeds from the exercise of the Pre-Funded Warrants, Series A Options, and Series B Options, if and when exercised, to the extent that they are exercised for cash. The Pre-Funded Warrants, Series A Options, and Series B Options, however, are also exercisable on a cashless basis under certain circumstances. For the purposes of this registration statement, we have assumed the full exercise for cash of the Pre-Funded Warrants, Series A Options, and Series B Options, in which case the gross proceeds of such exercise will be approximately $5,887,405. We intend to use those proceeds, if any, for funding of our research and development activities for our Virax Immune platform and for general corporate purposes.

A description of our share capital and our ordinary shares can be found in Exhibit 1.1 to our Annual Report on Form 20-F filed with the SEC on August 12, 2022 and is incorporated by reference herein.

Our authorized share capital consists of 50,000,000 ordinary shares, par value $0.0001 per share, of which 15,547,089 shares are issued and outstanding as of March 17, 2023.

All of our outstanding ordinary shares are validly issued, fully paid and non-assessable. Our ordinary shares are not redeemable and do not provide any preemptive rights.

Our Ordinary Shares are listing on the Nasdaq Capital Market under the symbol “VRAX”.

The transfer agent and registrar for our Ordinary Shares is Continental Stock Transfer & Trust Company. The transfer agent and registrar’s address is 1 State Street, 30th Floor, New York, NY 10004.

Unless the context otherwise requires, as used in this prospectus, “selling shareholders” includes the selling shareholders listed below and donees, pledgees, transferees or other successors-in-interest selling shares received after the date of this prospectus from the selling shareholders as a gift, pledge or other non-sale related transfer.

We have prepared this prospectus to allow the selling shareholders or their successors, assignees or other permitted transferees to sell or otherwise dispose of, from time to time, up to 11,453,062 ordinary shares, which are comprised of (i) 1,500,000 PIPE Shares, (ii) 2,343,309 Pre-Funded Warrant Shares, (iii) 3,497,412 Series A Option Shares, (iv) 3,843,309 Series B Option Shares, and (v) 269,032 Placement Warrant Shares.

The table below lists the selling shareholder and other information regarding the beneficial ownership of the Ordinary Shares by the selling shareholder. The second column lists the number of Ordinary Shares beneficially owned by the selling shareholder, based on its ownership of the Ordinary Shares, as of March 21, 2023. The third column lists the Ordinary Shares being offered by this prospectus by the selling shareholder. The fourth column assumes the sale of all of the shares offered by the selling shareholder pursuant to this prospectus.

This prospectus covers the resale of the sum of (i) the maximum number of PIPE Shares, (ii) the maximum number of Pre-Funded Warrant Shares, (iii) the maximum number of Series A Option Shares, and (iv) the maximum number of Series B Option Shares. The table below assumes that the outstanding warrants were exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, each as of the trading day immediately preceding the applicable date of determination and all subject to adjustment as provided in the PIPE Securities Purchase Agreement.

Under the terms of the Pre-Funded Warrants and the Preferred Options, a selling shareholder, who elected to be subject to such limitation (as indicated in the table below), may not exercise such warrants to the extent such exercise would cause such selling shareholder, together with its affiliates and attribution parties, to beneficially own a number of ordinary shares which would exceed 4.99% (or 9.99% at the election of the holder prior to the date of issuance), of our then outstanding ordinary shares following such exercise, excluding for purposes of such determination ordinary shares issuable upon the exercise of such Pre-Funded Warrants and Ordinary Warrants which have not been exercised. The number of shares in the second and fourth columns do not reflect this limitation. The selling shareholders may sell all, some or none of their shares in this offering.

On November 3, 2022, we entered into the November SPA, with the selling shareholder, pursuant to which we issued and sold to the selling stockholder 1,165,000 Ordinary Shares, pre-funded warrants to purchase 1,165,000 Ordinary Shares at an exercise price per share of $0.0001, and ordinary warrants to purchase up to 3,495,000 Ordinary Shares at an exercise price per share of $1.73, for gross proceeds of approximately $3.8 million. The Private Placement closed on November 8, 2022.

On March 8, 2023, we entered into the PIPE Securities Purchase Agreement, with the selling shareholder, pursuant to which we issued and sold to the selling stockholder (i) 1,500,000 Ordinary Shares; (b) Pre-Funded Warrants to purchase 2,343,309 Ordinary Shares, (iii) Series A Options to purchase 3,497,412 Ordinary Shares, and (iv) Series B Options to purchase 3,843,309 Ordinary Shares at a purchase price of $1.04077 per Ordinary Share and associated Preferred Options and a purchase price of $1.04067 per Pre-Funded Warrant and associated Preferred Options for gross proceeds of approximately $4.0 million. The Private Placement closed on March 10, 2023. The Preferred Options have an exercise price of $0.80202 per share, will become exercisable after their date of issuance

and will expire five and a half years from their initial date of exercise. The PIPE Securities Purchase Agreement contains customary representations and warranties and agreements of the Company and the purchaser and customary indemnification rights and obligations of the parties. The 2023 Private Placement closed on March 10, 2023. Concurrently with the signing of the PIPE Securities Purchase Agreement, we entered into a registration rights agreement to file with the Securities and Exchange Commission a registration statement covering the resale of all of the registrable securities under the registration rights agreement. In addition, warrants to purchase up to an aggregate of 3,495,000 ordinary shares which were previously issued in the 2022 Private Placement were cancelled simultaneously with the closing of 2023 Private Placement. In addition, the Company issued warrants to purchase up to 269,032 Ordinary Shares at $1.3010 per share to certain designees of H.C. Wainwright & Co., placement agent of the 2023 Private Placement.

Pursuant to the PIPE Securities Purchase Agreement and the Registration Rights Agreement, we agreed to prepare and file with the SEC within 15 days of the execution of the PIPE Securities Purchase Agreement a registration statement covering the resale of the PIPE Shares, Pre-Funded Warrant Shares underlying the Pre-Funded Warrants, Series A Option Shares underlying the Series A Options, and Series B Option Shares underlying the Series B Options, respectively, sold to the selling shareholder, and to use commercially reasonable best efforts to cause the registration statement to become effective within 45 days in the event of a review by the SEC. We agreed to use commercially reasonable best efforts to keep the registration statement effective until the date on which all of the securities sold in the 2023 Private Placement are sold by the selling shareholder. We are registering the shares to be sold by the selling stockholder under the registration statement of which this prospectus is a part to satisfy our obligation under the PIPE Securities Purchase Agreement.

Each Selling Shareholder (the “Selling Shareholders”) of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal Trading Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Shareholder may use any one or more of the following methods when selling securities:

The Selling Shareholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended (the "Securities Act"), if available, rather than under this prospectus.

Broker‑dealers engaged by the Selling Shareholders may arrange for other brokers‑dealers to participate in sales. Broker‑dealers may receive commissions or discounts from the Selling Shareholders (or, if any broker‑dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the Selling Shareholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Shareholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Shareholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Shareholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Shareholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Shareholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Shareholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the ordinary shares for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Shareholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the ordinary shares by the Selling Shareholders or any other person. We will make copies of this prospectus available to the Selling Shareholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

The costs and expenses payable by the Company in connection with the offerings described in this registration statement are set forth below. The selling stockholder will not bear any portion of such expenses.

The validity of the securities offered by this prospectus and other legal matters concerning this offering relating to Cayman Islands law will be passed upon for us by Ogier. Certain legal matters relating to U.S. law will be passed upon for us by Loeb & Loeb LLP.

The SEC allows us to “incorporate by reference” into this prospectus the information in documents we file with it. This means that we can disclose important information to you by referring you to another document filed by us with the SEC. Each document incorporated by reference is current only as of the date of such document, and the incorporation by reference of such documents shall not create any implication that there has been no change in our affairs since the date thereof or that the information contained therein is current as of any time subsequent to its date. The information incorporated by reference is considered to be a part of this prospectus and should be read with the same care. When we update the information contained in documents that have been incorporated by reference by making future filings with the SEC, the information incorporated by reference in this prospectus is considered to be automatically updated and superseded. In other words, in the case of a conflict or inconsistency between information contained in this prospectus and information incorporated by reference into this prospectus, you should rely on the information contained in the document that was filed later.

We incorporate by reference into this prospectus documents listed below and any future filings made with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, and, to the extent specifically designated therein, reports on Form 6-K we furnish to the SEC on or after the date on which this registration statement is first filed with the SEC and until the termination or completion of that offering under this prospectus:

Any statement contained herein or in a document all or a portion of which is incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded for purposes of this registration statement to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this registration statement.

Unless expressly incorporated by reference, nothing in this prospectus shall be deemed to incorporate by reference information furnished to, but not filed with, the SEC.

We are an exempted company with limited liability incorporated under the laws of the Cayman Islands and our affairs are governed by our second amended and restated memorandum and articles of association and the Companies Act, and the common law of the Cayman Islands. We are incorporated in the Cayman Islands because of certain benefits associated with being a Cayman Islands company, such as political and economic stability, an effective judicial system, a favorable tax system, the absence of foreign exchange control or currency restrictions and the availability of professional and support services. However, certain disadvantages accompany incorporation in the Cayman Islands. These disadvantages include, but are not limited to, the following: (i) the Cayman Islands has a less developed body of securities laws as compared to the United States and provides less protection for investors; and (ii) Cayman Islands companies may not have standing to sue before the federal courts of the United States.

Substantially all of our assets are located outside the United States. In addition, most of our directors and executive officers are nationals or residents of jurisdictions other than the United States and substantially all of their assets are located outside the United States. As a result, it may be difficult or impossible for you 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. It may also 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 executive officers and directors.

We have appointed Cogency Global Inc. as our agent to receive service of process with respect to any action brought against us in the United States in connection with this offering under the federal securities laws of the United States or of any State in the United States.

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

We have also been advised by Ogier that it is uncertain whether the courts of the Cayman Islands will allow shareholders of our company to originate actions in the Cayman Islands based upon securities laws of the United States. In addition, there is uncertainty with regard to Cayman Islands law related to whether a judgment obtained from the U.S. courts under civil liability provisions of U.S. securities laws will be determined by the courts of the Cayman Islands as penal or punitive in nature. If such a determination is made, the courts of the Cayman Islands will not recognize or enforce the judgment against a Cayman Islands company, such as our company. As the courts of the Cayman Islands have yet to rule on making such a determination in relation to judgments obtained from U.S. courts under civil liability provisions of U.S. securities laws, it is uncertain whether such judgments would be enforceable in the Cayman Islands. Ogier has further advised us that although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will recognize and enforce a foreign judgement, without any re-examination or re-litigation of matters adjudicated upon, provided such judgment:

(b) imposes on the judgment debtor a liability to pay a liquidated sum for which the judgment has been given;

(f) is not of a kind the enforcement of which is contrary to natural justice or the public policy of the Cayman Islands.

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

Singapore has no arrangement for the reciprocal enforcement of judgments with the United States. It is possible that the Singapore courts may not (i) recognize and enforce judgments of courts in the United States, based upon the civil liability provisions of the securities laws of the United States or any state or territory of the United States, or (ii) enter judgments in original actions brought in the Singapore courts based solely on the civil liability provisions of these securities laws. An in personam final and conclusive judgment in the federal or state courts of the United States under which a fixed or ascertainable sum of money is payable may generally be enforced as a debt in the Singapore courts under the common law as long as it is established that the Singapore courts have jurisdiction over the judgment debtor, subject to the applicable substantive and procedural laws of Singapore. Additionally, the court where the judgment was obtained must have had international jurisdiction over the party sought to be bound in the local proceedings. However, the Singapore courts are unlikely to enforce a foreign judgment if (a) the foreign judgment is inconsistent with a prior local judgment that is binding on the same parties; (b) the enforcement of the foreign judgment would contravene the public policy of Singapore; (c) the proceedings in which the foreign judgment was obtained were contrary to principles of natural justice; (d) the foreign judgment was obtained by fraud; or (e) the enforcement of the foreign judgment amounts to the direct or indirect enforcement of a foreign, penal, revenue or other public laws.

In particular, the Singapore courts may potentially not allow the enforcement of any foreign judgment for a sum payable in respect of taxes, fines, penalties or other similar charges, including the judgments of courts in the United States based upon the civil liability provisions of the securities laws of the United States or any state or territory of the United States. In respect of civil liability provisions of the United States federal and state securities law which permit punitive damages against us and our Directors or Executive Officers, we are unaware of any decision by the Singapore courts which has considered the specific issue of whether a judgment of a United States court based on such civil liability provisions of the securities laws of the United States or any state or territory of the United States is enforceable in Singapore.

There is uncertainty as to whether the courts of Hong Kong would (i) recognize or enforce judgments of United States courts obtained against us or our directors or officers predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States or (ii) entertain original actions brought in Hong Kong against us or our directors or officers predicated upon the securities laws of the United States or any state in the United States.

A judgment of a court in the United States predicated upon U.S. federal or state securities laws may be enforced in Hong Kong at common law by bringing an action in a Hong Kong court on that judgment for the amount due thereunder, and then seeking summary judgment on the strength of the foreign judgment, provided that the foreign judgment, among other things, is (1) for a debt or a definite sum of money (not being taxes or similar charges to a foreign government taxing authority or a fine or other penalty) and (2) final and conclusive on the merits of the claim, but not otherwise. Such a judgment may not, in any event, be so enforced in Hong Kong if (a) it was obtained by fraud; (b) the proceedings in which the judgment was obtained were opposed to natural justice; (c) its enforcement or recognition would be contrary to the public policy of Hong Kong; (d) the court of the United States was not jurisdictionally competent; or (e) the judgment was in conflict with a prior Hong Kong judgment.

Hong Kong has no arrangement for the reciprocal enforcement of judgments with the United States. As a result, there is uncertainty as to the enforceability in Hong Kong, in original actions or in actions for enforcement, of

judgments of United States courts of civil liabilities predicated solely upon the federal securities laws of the United States or the securities laws of any State or territory within the United States.

There is uncertainty as to whether the courts of China would (1) recognize or enforce judgments of United States courts obtained against us or such persons predicated upon the civil liability provisions of the securities laws of the United States or any state thereof, or (2) be competent to hear original actions brought in each respective jurisdiction, against us or such persons predicated upon the securities laws of the United States or any state thereof.

The recognition and enforcement of foreign judgments are mainly provided for under the Chinese Civil Procedure Law. Chinese courts may recognize and enforce foreign judgments in accordance with the requirements of the Chinese Civil Procedure Law and other applicable laws and regulations based either on treaties between China and the country where the judgment is made or in reciprocity between jurisdictions. Accordingly, there is uncertainty whether China courts will recognize or enforce judgments of United States or Cayman Islands Courts because China does not have any treaties or other agreements with the Cayman Islands or the United States that provide for the reciprocal recognition and enforcement of foreign judgments as of the date of this prospectus. Further, under Chinese Civil Procedure Law, Chinese courts will not enforce a foreign judgment against us or our officers and directors if the court decides that such judgment violates the basic principles of PRC law or national sovereignty, security or social public interest. As a result, it is uncertain whether and on what basis a PRC court would enforce a judgment rendered by a court in the United States or in the Cayman Islands.

Under the PRC Civil Procedure Law, foreign shareholders may originate actions based on PRC law against a company in China for disputes if they can establish sufficient nexus to the PRC for a PRC court to have jurisdiction, and meet other procedural requirements, including, among others, the plaintiff must have a direct interest in the case, and there must be a concrete claim, a factual basis and a cause for the suit. However, it will be difficult for U.S. shareholders to originate actions against us in the PRC in accordance with PRC laws because we are incorporated under the laws of the Cayman Islands and it will be difficult for U.S. shareholders, by virtue only of holding our ordinary shares, to establish a connection to the PRC for a PRC court to have jurisdiction as required under the PRC Civil Procedure Law.

We have filed with the SEC a registration statement on Form F-1, including amendments and relevant exhibits and schedules, under the Securities Act covering the Ordinary Shares to be sold in this offering. This prospectus, which constitutes a part of the registration statement, summarizes material provisions of contracts and other documents that we refer to in the prospectus. Since this prospectus does not contain all of the information contained in the registration statement, you should read the registration statement and its exhibits and schedules for further information with respect to us and our Ordinary Shares. Our SEC filings, including the registration statement, are also available to you on the SEC’s website at http://www.sec.gov. The SEC maintains a website (http://www.sec.gov) that contains reports, proxy and information statements and other information regarding registrants that file electronically with the SEC.

We are subject to the information reporting requirements of the Exchange Act that are applicable to foreign private issuers, and under those requirements we file reports with the SEC. Those other reports or other information may be inspected without charge at the locations described above. 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 within four months after the fiscal year end, or such applicable time as required by the SEC.
