TC BIOPHARM (HOLDINGS) PLC

We are offering in a best-efforts offering 215,000 American depositary shares, or ADSs representing ordinary shares, par value $0.0001 per share, together with Series C warrants to purchase up to 3,437,500 ADSs (the “Series C Ordinary Warrants”, or the “Warrants”). The ADSs and Warrants will be sold in a fixed combination, with each ADS accompanied by one Series C Ordinary Warrant to purchase one ADS. The ADSs and Warrants are immediately separable and will be issued separately in this offering, but must be purchased together in this offering. The Series C Ordinary Warrants will have an exercise price per share of $1.75 and will be immediately exercisable for a term of five years from the date of issuance.

We are also offering pre-funded warrants to purchase up to 3,222,500 ADSs to certain purchasers whose purchase of ADSs in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding ADSs immediately following the consummation of this offering. The public offering price of each pre-funded warrant and accompanying Ordinary Warrant will be equal to the price at which an ADS and accompanying Ordinary Warrant is sold to the public in this offering, minus $0.001, and the exercise price of each pre-funded warrant will be $0.001 per ADS. The pre-funded warrants will be immediately exercisable and may be exercised at any time until all of the pre-funded warrants are exercised in full. Pursuant to this prospectus, we are also registering the ADSs issuable upon exercise of the Series C Ordinary Warrants and pre-funded warrants.

There is no established public trading market for the Ordinary Warrants and pre-funded warrants, and we do not expect a market to develop. We do not intend to apply for listing of the Warrants and pre-funded warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the warrants will be limited.

This offering will terminate on April 14, 2023, unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The combined public offering price per ADS (or pre-funded warrant) and Ordinary Warrant will be fixed for the duration of this offering.

Our ADSs are listed on the Nasdaq Capital Market, or Nasdaq, under the symbol “TCBP”. On March 27, 2023, the closing trading price for our ADSs, as reported on Nasdaq, was $1.755 per ADS.

We have engaged H.C. Wainwright & Co., LLC, or the Placement Agent, to act as our exclusive placement agent in connection with this offering. The placement agent has agreed to use its reasonable best efforts to arrange for the sale of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities we are offering and the placement agent is not required to arrange the purchase or sale of any specific number of securities or dollar amount.

ABOUT THIS PROSPECTUS

Unless the context requires otherwise, in this prospectus TC BioPharm (Holdings) plc (formerly TC BioPharm (Holdings) Limited, which was re-registered as a public limited company on January 10, 2022) and its subsidiaries (“Subsidiar(y/ies)”), and TC BioPharm Limited (our principal trading subsidiary) shall collectively be referred to as “TCB,” “the Company,” “the Group”, “we,” “us,” and “our” unless otherwise noted.

On December 17, 2021, prior to our initial public offering, the Company undertook a corporate reorganization pursuant to which TC BioPharm (Holdings) plc became the group holding company. The Company in turn effected a forward split of its ordinary shares on a 10 for 1 basis. On November 18, 2022 the Company undertook a reverse share split such that fifty issued ordinary share were exchanged for one new ordinary share. As a result of the share splits, all references included in this document to units of ordinary shares or per share amounts are reflective of the forward and reverse share splits for all periods presented. In addition, the exercise prices and the numbers of ordinary shares issuable upon the exercise of any outstanding options to purchase ordinary shares were proportionally adjusted pursuant to the respective anti-dilution terms of the share-based payment plans.

ENFORCEABILITY OF CIVIL LIABILITIES

TCB is a corporation organized under the laws of Scotland. Substantially all of TCB’s assets and the majority of its directors and executive officers are located and reside, respectively, outside the United States. Because of the location of TCB’s assets and board members, it may not be possible for investors to serve process within the United States upon TCB or those persons with respect to matters arising under the United States federal securities laws or to enforce against TCB or persons located outside the United States judgments of United States courts asserted under the civil liability provisions of the United States federal securities laws.

TCB understands that there is doubt as to the enforceability in Scotland and the United Kingdom, 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 insofar as they are fines or penalties. In addition, awards of punitive damages in actions brought in the United States or elsewhere may be unenforceable in Scotland and the United Kingdom by reason of being a penalty.

TC BioPharm (North America) Inc., a Delaware corporation, with a registered office at Business Filings, Inc. 108 West 13th Street, Wilmington, Delaware 19801, has been appointed agent to receive service of process in any action against TC BioPharm (Holdings) plc in any state or federal court in the State of New York.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

TCB discusses in this prospectus its business strategy, market opportunity, capital requirements, product introductions and development plans and the adequacy of the Company’s funding. Other statements contained in this prospectus, which are not historical facts, are also forward-looking statements. TCB has tried, wherever possible, to identify forward-looking statements by terminology such as “may,” “will,” “could,” “should,” “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates” and other comparable terminology.

TCB cautions investors that any forward-looking statements presented in this prospectus, or that TCB may make orally or in writing from time to time, are based on the beliefs of, assumptions made by, and information currently available to, TCB. These statements are based on assumptions, and the actual outcome will be affected by known and unknown risks, trends, uncertainties and factors that are beyond its control or ability to predict. Although TCB believes that its assumptions are reasonable, they are not a guarantee of future performance, and some will inevitably prove to be incorrect. As a result, its actual future results can be expected to differ from its expectations, and those differences may be material. Accordingly, investors should use caution in relying on forward-looking statements, which are based only on known results and trends at the time they are made, to anticipate future results or trends. Certain risks are discussed in this prospectus and also from time to time in TCB’s other filings with the Securities and Exchange Commission (“SEC”).

This prospectus and all subsequent written and oral forward-looking statements attributable to the Company or any person acting on its behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. The Company does not undertake any obligation to release publicly any revisions to its forward-looking statements to reflect events or circumstances after the date of this prospectus.

In particular, you should consider the risks provided under “Risk factor summary” in this prospectus and in the Form 20-F for the fiscal year ended December 31, 2021 as filed with the Securities and Exchange Commission (the “2021 Form 20-F”) incorporated by reference in this prospectus.

The Company

Corporate Overview

TCB based in Scotland, is a clinical-stage biopharmaceutical company focused on developing novel immunotherapy products that are based on its proprietary allogeneic gamma delta T (abbreviated as GD-T) cell platform. Harnessing the innate ability of GD-Ts has enabled TCB to develop a range of clinical-stage cell therapies designed to combat identified cancers and viral infections.

Having generated meaningful clinical data showing our product is well tolerated in late-stage acute myeloid leukemia (AML) patients, TCB is now embarking on phase 2-into-pivotal (phase 3) clinical studies to treat AML in patients who have failed to respond adequately to induction therapy, and treated its first patient under this study in Q4 2022. Our unmodified cell therapy, used in the treatment of Acute Myeloid Leukemia, is supplied under the name OmnImmune® and our proposed phase 2-into-pivotal (phase 3) trial is called ACHIEVE. Clinical results generated thus far have enabled TCB to obtain FDA orphan drug status for its method of treatment of AML.

In addition to unmodified allogenic GD-Ts for treatment of blood cancers, TCB is also developing an innovative range of genetically modified chimeric antigen receptor modified T cell (abbreviated as CAR-T) products for treatment of solid cancers. TCB believes that solid cancers are more difficult to treat than blood cancers and may require addition of a chimeric antigen receptor (abbreviated as CAR) to (i) help therapeutic cells ‘navigate’ into diseased cancerous tissue, and (ii) retain therapeutic cells in-situ at the lesion for maximum efficacy.

At this stage, we do not have any approved products. Accordingly, we have not generated any revenue from the sale of products, and we do not expect to generate any such revenue unless and until we obtain regulatory approvals for, and commercialize any of, our product candidates. In the future, we will seek to generate revenue primarily from product sales and, potentially, regional or global collaborations with strategic partners, which may produce license fee income.

See “Business - Overview” in our 2021 Form 20-F incorporated by reference in this prospectus.

Patent Portfolio and Intellectual Property

We believe TCB has a strong portfolio of patents and licenses covering the manufacture and commercialization of GD-T cell products and their modification via CAR-T. We own six granted patents and 45 patent applications in four patent families and have an exclusive license to an additional one family of six granted patents and ten patent applications. We protect our proprietary position, generally, by filing an initial priority filing at the United Kingdom Intellectual Property Office, or UKIPO, followed by patent applications under the Patent Co-operation Treaty claiming priority from the initial application(s) and then progressing to national applications in, for example, the United States, Europe, Japan, China, Australia, New Zealand, South Korea, Israel and Canada.

As a platform technology, we believe the co-stimulatory CAR-T GD-T cell system has a wealth of potential options to build added functionality. We plan to continue to innovate and partner in the field to augment our drug products and introduce next generation attributes. We will also continue to innovate our manufacturing and supply chains to efficiently scale our processes and simplify the interface with patients and healthcare professionals, whilst continually seeking to reduce manufacturing costs to improve patient access.

We intend to continue building on our technology platform, comprised of intellectual property, proprietary methods and know-how in the field of GD-T cells. These assets form the foundation for our ability, not only to strengthen our product pipeline, but also to successfully defend and expand our position as a leader in the field of GD-T based immuno-oncology.

See “Business - Intellectual Property” in our 2021 Form 20-F incorporated by reference in this prospectus.

Our Product Strategy

Our strategic objective is to build a global therapeutic business with an extensive portfolio based upon unmodified and modified gamma delta T cells (GD-T) with the potential to significantly improve the outcomes of patients with cancer and infectious disease.

Our strategy is to take a step-wise approach to clinical development and commercialization. After our inception, we made clinical transitions from autologous GD-Ts to allogeneic GD-Ts to CAR-modified allogeneic GD-Ts. Our commercialization strategy is to introduce clinical studies for products firstly in blood cancers (AML initially) and then solid tumor indications. Complementarily, since GD-T cells are dysfunctional in patients with severe viral diseases, TCB plans to develop its unmodified GD-T product to treat infectious diseases and believes that this approach may be particularly relevant in relation to the treatment of viral pandemics.

Since 2015, TCB has built and maintained cell therapy medicinal product manufacturing facilities for Investigational Medicinal Products MIA (abbreviated IMP), operated under license from the United Kingdom Medicines and Healthcare Products Regulatory Agency (abbreviated MHRA). In April 2016, the MHRA granted a ‘Specials’ license to TCB, which allows it to treat patients under supervision of a qualified doctor outside a clinical trial, and approved the company’s facility for ongoing Good Manufacturing Process (“GMP”) compliance, which permits the manufacture and release of Advanced Therapy Medicinal Products (abbreviated ATMPs) for use in clinical trials. TCB maintains a rigorous Quality Management System, which is based on the principles of the current GMP of the European and UK law and regulation and EudraLex Volume 4, as revised. The Company complies with the two directives laying down principles and guidelines of GMP for medicinal products adopted by the Commission. Directive 2003/94/EC applies to medicinal products for human use and Directive 91/412/EEC for veterinary use. Detailed guidelines in accordance with those principles are published in the Guide to Good Manufacturing Practice which will be used in assessing applications for manufacturing authorizations and as a basis for inspection of manufacturers of medicinal products.

Regulatory approval of all aspects of medicinal therapy development, testing, manufacture and commercialization always is of concern. In the case of treatment for AML, TCB has developed the novel approach of antibody-based immunotherapy and adoptive cell therapy with the aim to improve anti-leukemia T cell function. Therefore, TCB is able to take advantage of orphan medicine regulation provided by the European Medicines Agency (abbreviated EMA) and the United States Federal Drug Administration (abbreviated FDA), which are designed to encourage medicine development for small numbers of patients where there is little commercial incentive under normal market conditions.

Part of our strategy is to collaborate with appropriate partners from time to time.

See “Business - Business Strategy” in our 2021 Form 20-F incorporated by reference in this prospectus.

TCB’s Strengths

TCB believes it has certain identified strengths. These include:

Corporate Information

Our principal executive offices are located in Scotland, United Kingdom, with a mailing address of Maxim 1, 2 Parklands Way, Holytown, Motherwell, ML1 4WR, United Kingdom and our telephone number at that location is +44 (0) 141 433 7557. Our website address is https://www.tcbiopharm.com. The information contained on, or that can be accessed through, our website is not part of this prospectus. We have included our website address in this prospectus solely as an inactive textual reference.

Implications of Being an “Emerging Growth Company”

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, or the Securities Act. As such, we are eligible to, and intend to, take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not “emerging growth companies” such as not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting of Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act. We could remain an “emerging growth company” for up to five years, or until the earliest of (a) the last day of the first fiscal year in which our annual gross revenue exceeds $1.07 billion, (b) the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, which would occur if the market value of all our ordinary shares, including those represented by the ADSs, that are held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, or (c) the date on which we have issued more than $1 billion in nonconvertible debt during the preceding three-year period.

Implications of being a “Foreign Private Issuer”

We are subject to the information reporting requirements of the Securities and Exchange Act of 1934, as amended, the Exchange Act, that are applicable to “foreign private issuers,” and under those requirements we file reports with the SEC. As a foreign private issuer, we are not subject to the same requirements of the SEC applicable to U.S. domestic issuers. Under the Exchange Act, we are subject to reporting obligations that, in certain respects, are less detailed and less frequent than those of U.S. domestic reporting companies. For example, we are not required to issue quarterly reports, proxy statements that comply with the requirements applicable to U.S. domestic reporting companies, or individual executive compensation information that is as detailed as that required of U.S. domestic reporting companies. We also have four months after the end of each fiscal year to file our annual report with the SEC and are not required to file current reports as frequently or promptly as U.S. domestic reporting companies. Our officers, directors and principal shareholders are exempt from the requirements to report transactions in our equity securities and from the short-swing profit liability provisions contained in Section 16 of the Exchange Act. As a foreign private issuer, we are not subject to the requirements of Regulation FD (Fair Disclosure) promulgated under the Exchange Act. In addition, as a foreign private issuer, we are permitted to follow certain home country corporate governance practices instead of those otherwise required under the Nasdaq Stock Market rules for domestic U.S. issuers and are not required to be compliant with all Nasdaq Stock Market rules as of the date of our initial listing on Nasdaq as would domestic U.S. issuers These exemptions and leniencies will reduce the frequency and scope of information and protections available to you in comparison to those applicable to a U.S. domestic reporting company. We intend to take advantage of the exemptions available to us as a foreign private issuer during and after the period we qualify as an “emerging growth company.”

Recent Developments

Share Consolidation

On November 14, 2022, the Company held a general meeting of shareholders (the “Meeting”). The purpose of the Meeting was to carry out, among other things, a proposed one for fifty reverse stock split of the ordinary share capital of the Company. The reverse stock split was approved by shareholders on November 14, 2022. The Company completed a reverse stock split of one (1) new share for every fifty (50) existing shares effective November 21, 2022. As a result, the Company’s depositary bank, BNY Mellon has effected an identical reverse stock split on the Company’s American Depositary Receipt (“ADR”) program. The ADR trading price increased proportionally at the open of trading on November 21, 2022, although the Company can give no assurance that the ADR trading price after the change in the reverse stock split will be equal to or greater than fifty times the ADR trading price before the change.

Effective November 21, 2022, the Company’s ADR holders were required on a mandatory basis to surrender their old ADR(s) to BNY Mellon for cancellation and exchange to receive one (1)” New” American Depositary Share (“ADS”) (CUSIP: 87807D202) for every fifty (50) “Old” ADSs (CUSIP: 87807D103). Holders of ADSs in the Direct Registration System or in brokerage accounts had their ADRs automatically exchanged. No fraction of an ADS was issued and BNY Mellon undertook to attempt to sell any fractions and distribute the cash proceeds to ADR holders.

In addition, the Company’s public warrants (the “Public Warrants”), were amended in accordance with the terms of the Warrant Agreement, whereby if the Company at any time while the Warrants are outstanding, enters into a reverse stock split, an adjustment is made to the exercise price and the proportion of ADSs issued upon exercise of a Warrant in accordance with Section 5 of the Agency Agreement. As such, upon the consummation of the reverse stock split, the exercise price of the Warrants was increased from $0.50 to $25.00 and the proportion of ADSs issued upon exercise of each Warrant was proportionally adjusted from one Warrant for one ADS to fifty Warrants for one ADS such that the aggregate Exercise Price of each Warrant remained unchanged.

November 2022 Financing

On November 27, 2022, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain accredited investors (the “Investors”) as purchasers. Pursuant to the Purchase Agreement, the Company sold, and the Investors purchased in a private placement certain “ADSs, Pre-Funded Warrants, and Ordinary Warrants for aggregate gross proceeds of $7,350,000, excluding any proceeds that may be received upon exercise of the Ordinary Warrants. The purchase price for each ADS and associated Ordinary Warrants was $5.00 and the purchase price per each Pre-Funded Warrant and associated Ordinary Warrants was $4.999. The offering closed on November 30, 2022.

The Series A Ordinary Warrants were immediately exercisable, will expire five and one-half (5.5) years from the date of issuance and have an exercise price of $5.00 per ADS, subject to adjustment as set forth therein. The Series B Ordinary Warrants were immediately exercisable, will expire thirty (30) months from the date of issuance and have an exercise price of $5.00 per ADS, subject to adjustment as set forth therein.

The Company and the Investors also entered into a registration rights agreement, dated as of November 27, 2022 (the “Registration Rights Agreement”) whereby the Company shall use its best efforts to file a registration statement registering the resale of the securities issued pursuant to the Purchase Agreement within 15 days following the date of the Registration Rights Agreement. The Company agreed to use is best efforts to have the registration statement declared “effective” within 45 days following the date of the Registration Rights Agreement. The registration statement was subsequently declared effective on December 23, 2022. If the Company fails to maintain the effectiveness of the registration statement until all of such securities have been sold, then we will be obligated to pay liquidated damages to the Investors, in addition to any other rights the Investors may have, upon the occurrence of any such event and on each monthly anniversary thereafter until the event is cured, an amount equal to the product of 1.5% multiplied by the aggregate subscription amount paid by the Investors pursuant to the Purchase Agreement, provided, however, the aggregate amount payable shall not exceed 10% of each Investor’s subscription amount.

From the date of the Purchase Agreement until sixty (60) days after the Effective Date (as defined in the Purchase Agreement), neither the Company nor any Subsidiary shall (i) issue, enter into any agreement to issue or announce the issuance or proposed issuance of any ADSs, Ordinary Shares or Ordinary Share Equivalents or (ii) file any registration statement or any amendment or supplement thereto, in each case other than as contemplated pursuant to the Registration Rights Agreement.

The Company also entered into a letter agreement (the “Engagement Agreement”) with H.C. Wainwright & Co., LLC (the “Placement Agent”), pursuant to which the Placement Agent agreed to serve as the exclusive placement agent for the Company in connection with the offering. The Company paid the Placement Agent a cash fee equal to 7.5% of the gross proceeds from the sale of the ADSs and associated Ordinary Warrants in the offering and a management fee of 1.0% of the gross proceeds from the sale of the ADSs. The Placement Agent will also receive a cash fee equal to 7.5% of the gross proceeds received by the Company upon the exercise of any Ordinary Warrants by the Investors. The Placement Agent or its designees also received warrants to purchase up to 110,250 ADSs (the “Placement Agent Warrants”) on substantially the same terms as the Series A Ordinary Warrants except that the Placement Agent Warrants have an exercise price equal to 125% of the offering price, or $6.25 per ADS. The Company also paid the Placement Agent $85,000 for non-accountable expenses.

Warrant Amendment Agreement

In connection with this offering, the Company has agreed that certain existing warrants to purchase up to an aggregate of 2,800,000 ADSs of the Company that were previously issued on November 30, 2022, at an exercise price of $5.00 per ADS and expiration dates of May 30, 2025 and May 30, 2028, will be amended effective upon the closing of the offering so that the amended warrants will have a reduced exercise price of $1.75 per ADS.

RISK FACTOR SUMMARY

Our business is subject to a number of risks and uncertainties, including those risks discussed at length in Item 3D (“Risk Factors”) in our 2021 Form 20-F incorporated into this prospectus by reference. These risks include among others those summarized below. Investing in our company and its securities involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this prospectus, including the information incorporated by reference to our 2021 Form 20-F, before investing in our company and our securities. If any of these risks materialize, our business, financial condition, operating results and prospects could be materially and adversely affected. In that event, the price or value of our ADSs in the public market could decline, and you could lose part or all of your investment.

The following is a summary of some of the principal risks we face. The list below is not exhaustive, and investors should read the risks described under the heading “Risk Factors” in our 2021 Form 20-F incorporated by reference herein, as well as the additional risks set forth in this section, in full.

Risks Related to this Offering and Ownership of ADSs

The price of the ADSs has been, and is likely to continue to be, highly volatile, which could result in substantial losses for purchases of ADSs in this offering.

The price of the ADSs has been, and is likely to continue to be, highly volatile. The stock market in general and the market for smaller pharmaceutical and biotechnology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, purchasers of securities sold pursuant to this registration statement may not be able to sell their ADSs at or above the price paid by such purchasers and, as such, they may lose some or all of their investment. Additionally, in the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us in light of the significant stock price volatility we and other pharmaceutical companies have experienced in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

We have broad discretion in the use of the net proceeds from this offering and any exercise of the Warrant and consequently may not use them effectively.

Our management will have broad discretion in the application of the net proceeds from this offering and any exercise of any Warrant and could spend any such proceeds in ways that do not improve our results of operations or enhance the value of our ADSs. The failure by our management to apply these funds effectively could result in financial losses that could cause the price of our ADSs to decline and delay the development of our product candidates.

If we fail to meet the requirements for continued listing on the Nasdaq Global Market or Nasdaq, our ADSs could be delisted from trading, which would decrease the liquidity of our ADSs and our ability to raise additional capital.

Our ADSs are currently listed for quotation on The Nasdaq Capital Market. We are required to meet specified financial requirements in order to maintain our listing on the Nasdaq Capital Market. These requirements include maintaining a minimum bid price of at least $1.00 per share for our ADSs, which is referred to as the Bid Price Rule, maintaining a minimum market value of listed securities, or the MVLS, of $35,000,000. On July 12 and 15, 2022, we received deficiency letters from the Listings Qualifications Department of the Nasdaq Stock Market notifying that we were not in compliance with the Bid Price Rule and the MVLS, respectively.

On December 6, 2022, we received written notification from the listing qualifications staff of the Nasdaq Stock Market, LLC (“Nasdaq”) indicating that the Company regained compliance with the Bid Price Rule. On January 12, 2023, we received written notification from the listing qualifications staff of the Nasdaq indicating that we have not regained compliance with the MVLS and that our securities would be subject to delisting unless we timely request a hearing before a Nasdaq Hearings Panel (the “Panel”). On March 9, 2023 the Company presented a formal plan to regain compliance to the Panel. On March 17, 2023, the Company announced that the TC BioPharm (Holdings) plc has been granted a formal extension until June 30, 2023, to regain compliance under Nasdaq Listing Rule 5550(b)(2) or its alternative criteria. During the extension period, the Company is obligated to meet certain milestones and the Panel has reserved the right to reconsider the terms of the exception in circumstances where, in its opinion, the continued listing of the Company’s securities is inadvisable or unwarranted. Nasdaq’s extension notice had no immediate effect on the listing or trading of TC BioPharm’s Common Stock, which continues to trade on the Nasdaq Capital Market under the symbol “TCBP”. There can be no assurance that the Panel will determine to continue the Company’s listing on The Nasdaq Capital Market or that the Company will timely evidence compliance with the terms of the extension that was granted by the Panel following the hearing.

The Company continues to execute its business plan and is looking into various options available to regain compliance with Nasdaq’s continued listing standards and maintain its continued listing on the Nasdaq Capital Market. However, there can be no assurance that the Company will be able to regain compliance with the MVLS requirement or will otherwise be in compliance with other Nasdaq listing rules.

There is no public market for Warrants or pre-funded warrants being offered by us in this offering.

There is no established public trading market for the Warrants or pre-funded warrants, and we do not expect a market to develop. In addition, we do not intend to apply to list the Warrants or pre-funded warrants on any national securities exchange or other nationally recognized trading system. Without an active market, the liquidity of the Warrants or pre-funded warrants will be limited.

The Warrants and pre-funded warrants are speculative in nature.

The Warrants and pre-funded warrants offered hereby do not confer any rights of ADS ownership on their holders, such as voting rights, but rather merely represent the right to acquire shares of ADS at a fixed price. Specifically, holders of the pre-funded warrants may acquire the ADSs issuable upon exercise of such warrants at an exercise price of $0.001 per ADS. Moreover, following this offering, the market value of the Warrants and pre-funded warrants is uncertain and there can be no assurance that the market value of the Warrants and pre-funded warrants will equal or exceed their respective public offering prices. There can be no assurance that the market price of the ADSs will ever equal or exceed the exercise price of the Warrants and pre-funded warrants, and consequently, whether it will ever be profitable to exercise the Warrants or the pre-funded warrants.

Holders of the Warrants offered hereby will have no rights as ADS holders with respect to the ADSs underlying the Warrants until such holders exercise their warrants and acquire our ADSs, except as otherwise provided in the Warrants.

Until holders of the warrants and pre-funded warrants acquire ADSs upon exercise thereof, such holders will have no rights with respect to the ADSs underlying such Warrants, except to the extent that certain rights may be granted to warrant holders as set forth in the warrants. Upon exercise of the Warrants and pre-funded warrants, the holders will be entitled to exercise the rights of an ADS holder only as to matters for which the record date occurs after the exercise date.

This is a best efforts offering, no minimum amount of securities is required to be sold, and we may not raise the amount of capital we believe is required for our business plans, including our near-term business plans.

The placement agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities in this offering. The placement agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth above. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to support our continued operations, including our near-term continued operations. Thus, we may not raise the amount of capital we believe is required for our operations in the short-term and may need to raise additional funds, which may not be available or available on terms acceptable to us.

You will experience immediate dilution in the book value per ADS purchased in the offering.

Because the price per share of our ADSs being offered may be higher than the net tangible book value per ADS, you will experience dilution to the extent of the difference between the offering price per ADS you pay in this offering and the net tangible book value per ADS immediately after this offering. Our net tangible book value as of June 30, 2023, was approximately $0.5 million, or $0.77 per ADS. Net tangible book value per ADS is equal to our total tangible assets minus total liabilities, all divided by the number of ADSs outstanding. See the section titled “Dilution” for a more detailed discussion of the dilution you will incur if you purchase shares in this offering.

If you purchase our securities in this offering you may experience future dilution as a result of future equity offerings or other equity issuances.

In order to raise additional capital, we believe that we will offer and issue additional ADSs or other securities convertible into or exchangeable for our ADSs in the future. We cannot assure you that we will be able to sell ADSs or other securities in any other offering at a price per ADS that is equal to or greater than the price per ADS paid by investors in this offering, and investors purchasing other securities in the future could have rights superior to existing stockholders. The price per ADS at which we sell additional ADSs or other securities convertible into or exchangeable for our ADSs in future transactions may be higher or lower than the price per ADS in this offering.

In addition, we have a significant number of share options and warrants outstanding. To the extent that outstanding share options or warrants have been or may be exercised or other shares issued, you may experience further dilution. Further, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans.

The exercise of outstanding ADS purchase warrants and share options will have a dilutive effect on the percentage ownership of our capital stock by existing stockholders.

As of March 27, 2023, we had outstanding warrants to acquire 3,387,724 ADSs, and share options to purchase 174,781 shares of our ordinary shares. A significant number of such warrants have exercise prices above our ADSs’ recent trading prices, but the holders have the right to effect a cashless exercise of such warrants. If a significant number of such warrants and share options are exercised by the holders, the percentage of our ADSs owned by our existing ADS holders will be diluted.

We are in default under our outstanding convertible notes and as a result, the noteholder may accelerate amounts owed under such notes and could foreclose upon the assets securing our obligations and our liquidity could be adversely impacted.

We are currently in default under our existing convertible notes. Upon the occurrence and during the continuance of an event of default under the notes, the holder has the option, among other things, to accelerate the debt, which was in the amount of $0.8 million as of March 27, 2023, which could severely affect our liquidity and significantly harm our business. The holder has not exercised any remedies under the notes as of the date of this prospectus. We are currently negotiating with the holder of the notes to remedy all events of default and potentially exchange all indebtedness for other securities of the Company. However, we cannot guarantee any negotiations will ever materialize or that we will not enter into default under the Notes in the future. In the event that we continue in default and/or re-enter into default under the notes, and such holder was to assert an event of default and demand repayment pursuant to the terms of the notes, our business, operating results and financial condition would be adversely affected.

Purchasers who purchase our securities in this offering pursuant to a securities purchase agreement may have rights not available to purchasers that purchase without the benefit of a securities purchase agreement.

In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers that enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The ability to pursue a claim for breach of contract provides those investors with the means to enforce the covenants uniquely available to them under the securities purchase agreement including: (i) timely delivery of shares; (ii) agreement to not enter into variable rate financings for one year from closing, subject to certain exceptions; (iii) agreement to not enter into any financings for sixty (60) days from closing; and (iv) indemnification for breach of contract.

Unstable market and economic factors could adversely affect our business, financial condition or results of operations.

Uncertain or unfavorable global economic or market conditions, such as a recession, an economic slowdown, inflation or reduced growth rates, could significantly impact our operating results or lead to significant reductions in funding sources available to the Company, which could adversely affect our business, results of operations or financial condition. Our operations have required substantial amounts of cash since inception. We expect to continue to spend substantial amounts to continue the development of our GD-T cell-based therapeutic candidates, including for future clinical trials. In the even of unstable markets and unfavorable market conditions, we cannot be certain that additional funding will be available on acceptable terms, or at all. We have no committed source of additional capital. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of our GD-T cell-based therapeutic candidates or other research and development initiatives. Furthermore, uncertain or unfavorable global economic or market conditions may cause our manufacturers, suppliers, distributors, contractors, logistics providers and other external business partners to suffer financial or operational difficulties, which could impact their ability to provide us with or distribute finished product, raw and packaging materials or services in a timely manner or at all. We could also face difficulty collecting or recovering accounts receivables from third parties facing financial or operational difficulties.

DIVIDEND POLICY

Since inception, we have not declared or paid any dividends on our ordinary shares. We do not have any current plans to pay any dividends on our ordinary shares, including those represented by ADSs, in the foreseeable future. We intend to retain all our available funds and any future earnings to operate and expand our business. Because we do not anticipate paying any cash dividends in the foreseeable future. Capital appreciation, if any, will be your sole source of gains, and you may never receive a return on your investment.

The determination to pay dividends, if any, will be made at the discretion of our board of directors and may be based on a number of factors, including our future operations and earnings, capital requirements and surplus, general financial condition, contractual and legal restrictions and other factors that the board of directors may deem relevant.

Under current Scottish law, among other things, a company’s accumulated realized profits must exceed its accumulated realized losses (on a non-consolidated basis) before dividends can be paid. Accordingly, we may only pay dividends if we have sufficient distributable reserves (on a non-consolidated basis), which are our accumulated realized profits that have not been previously distributed or capitalized less our accumulated realized losses, so far as such losses have not been previously written off in a reduction or reorganization of capital.

USE OF PROCEEDS

We estimate that our net proceeds from this offering will be approximately $4.6 million, after deducting estimated offering expenses of approximately $0.9 million. We will not receive any proceeds from the sale of ADSs issuable upon exercise of the Warrants that we are offering unless and until such Warrants are exercised.

If all of the warrants (Series C Ordinary Warrants to purchase 3,437,500 ADS, including the Placement Agent warrants to purchase 257,813 ADSs issued in connection with this offering are fully exercised for cash, we would receive additional aggregate proceeds of approximately $6.5 million. We cannot predict when or if these Series C Ordinary Warrants will be exercised. It is possible that these Series C Ordinary Warrants may expire and may never be exercised. Additionally, the Series C Ordinary Warrants contain a cashless exercise provision that permit exercise of Series C Ordinary Warrants on a cashless basis at any time where there is no effective registration statement under the Securities Act covering the issuance of the underlying ADSs.

We intend to use the net proceeds of this offering to advance our preclinical and clinical pipeline, and for continuing operating expenses and working capital.

The amounts and timing of our actual expenditures will depend on numerous factors, including the progress of our clinical trials, the potential for achieving accelerated regulatory approval and the amount of cash used in our operations. We therefore cannot estimate with certainty the amount of net proceeds to be used for the purposes described above. We may find it necessary or advisable to use the net proceeds for other purposes, and we will have broad discretion in the application of the net proceeds. Our shareholders may not agree with the manner in which our management chooses to allocate and spend the net proceeds. Moreover, our management may use the net proceeds for corporate purposes that may not result in our being profitable or increase our market value.

Pending these uses, we plan to invest these net proceeds in short-term, interest-bearing obligations; investment-grade instruments; certificates of deposit; or direct or guaranteed obligations of the United States and the United Kingdom. The goal with respect to the investment of these net proceeds is capital preservation and liquidity so that such funds are readily available to fund our operations. Our investment positions will also take into consideration the law and rules under the U.S. Investment Company Act of 1940, so as to avoid being characterized as an investment company thereunder.

CAPITALIZATION

You should read this information together with our unaudited condensed consolidated interim financial statement data as at June 30, 2022 and for the six months ended June 30, 2022 included in our Form 6-K (filed on December 12, 2022 and incorporated by reference in this prospectus and our 2021 audited consolidated financial statements and related notes of TC BioPharm (Holdings) plc included in our 2021 Form 20-F annual report and incorporated by reference in this prospectus and the information set forth under the sections titled “Use of Proceeds” and “Item 5. Operating and Financial Review and Prospects” included in our 2021 Form 20-F annual report and incorporated by reference.

The following table sets forth our cash and cash equivalents, indebtedness and capitalization as of June 30, 2022, on:

(1) an actual basis after giving retrospective effect to the 50 for 1 reverse share;

(2) a pro forma basis to give effect to (i) the split and a sub-division of every Ordinary share with a nominal value of £0.50 into one new Ordinary Share with a nominal value of £0.0001 and one deferred share with a nominal value of £0.4999 completed on November 18, 2022; (ii) the accrued interest on the Convertible Loan Notes outstanding at June 30, 2022 up to March 27, 2023; (iii) the issue, on August 9, 2022, of 3,676 Ordinary Shares and Warrants for 7,352 Ordinary Shares on conversion of Convertible Loan Notes (including the interest accrued to August 9, 2022) pursuant to the provisions of such notes; (iv) the repayment, on August 9, 2022, of Convertible Loan Notes with a value (including the interest accrued to August 9, 2022) totaling $832,116 pursuant to the provisions of such notes; (v) the issue, in connection with the administration of a 50 for 1 reverse share split on November 24, 2022, of 4 Ordinary Shares; (vi) the sale of 155,000 ADSs and pre-funded Warrants for 1,315,000 ADSs in November 2022, (vii) the issue of Series A Ordinary Warrants to purchase up to 1,470,000 ADSs, Series B Ordinary Warrants to purchase up to 1,470,000 ADSs and Representative Warrants to purchase up to 110,250 ADS in the November 2022 Financing; (viii) the subsequent exercise of pre-funded Warrants for 1,315,000 ADSs during January 2023; (ix) the amendment to reflect that certain existing warrants to purchase up to an aggregate of 2,800,000 ADSs of the Company that were previously issued on November 30, 2022, at an exercise price of $5.00 per ADS and expiration dates of May 30, 2025 and May 30, 2028, will be amended effective upon the closing of the offering so that the amended warrants will have a reduced exercise price of $1.75 per ADS; and (x) the movement in the fair value of the Warrants outstanding as at March 27, 2023.

(3) a pro forma basis as adjusted to give effect to the sale of the sale of 215,000 ADSs and pre-funded Warrants for 3,222,500 ADSs and 3,437,500 Series C Ordinary Warrants pursuant to this prospectus at a public offering price of $1.60 per one ADS and accompanying warrant in this offering.

[1] Represents the fair value as of March 27, 2023 of the Warrants to purchase up to 3,387,724 ADSs.

The number of our ordinary shares (including shares represented by ADSs) to be outstanding after this offering is based on 2,264,958 ordinary shares outstanding as of March 27, 2023 and excludes:

For the description of the 2014 Share Option Scheme and 2021 Share Option Scheme see “Item 6.E Share Ownership” in the 2021 Form 20-F, which is incorporated by reference herein.

Unless otherwise stated, all information in this prospectus assumes no exercise of the outstanding options described above into ordinary shares or ADSs, treats all restricted shares issued with outstanding restrictions to be vested as issued and outstanding shares, no exercise of the Series C Ordinary Warrants or the Placement Agent Warrants issued in this offering and no sale of pre-funded warrants in this offering.

Except as otherwise indicated all references to our articles of association in this prospectus refer to our articles of association, as amended as currently in force for TC BioPharm (Holdings) plc at the date of this prospectus.

To the extent these outstanding options or any newly issued options are exercised, or we issue additional ordinary shares in the future, there will be further dilution to the new investors purchasing ordinary shares represented by ADSs in this offering. In addition, we may choose to raise additional capital because of market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. If we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our shareholders.

DILUTION

If you invest in our ADSs in this offering, your ownership interest of our ordinary shares will be immediately diluted to the extent of the difference between the public offering price per ADS in this offering and the pro forma as adjusted net tangible book value per ADS after this offering. For the purposes of calculating the potential impact of dilution, the full value of the offering price of $1.60 per ADS has been ascribed to the ADSs. Dilution results from the fact that the public offering price per ADS is substantially in excess of the net tangible book value per ADS.

As of June 30, 2022, we had a historical net tangible book value of £0.5 million, or £0.63 per ADS (equivalent to $0.77 per ADS). Our net tangible book value per ADS represents total tangible assets less total liabilities, divided by the number of ordinary shares outstanding on June 30, 2022.

After giving further effect to (i) the split and a sub-division of every Ordinary share with a nominal value of £0.50 into one new Ordinary Share with a nominal value of £0.0001 and one deferred share with a nominal value of £0.4999 completed on November 18, 2022; (ii) the accrued interest on the Convertible Loan Notes outstanding at June 30, 2022 up to March 27, 2023; (iii) the issue, on August 9, 2022, of 3,676 ADSs and Warrants for 7,352 ADSs on conversion of Convertible Loan Notes (including the interest accrued to August 9, 2022) pursuant to the provisions of such notes; (iv) the repayment, on August 9, 2022, of Convertible Loan Notes with a value (including the interest accrued to August 9, 2022) totaling $832,116 pursuant to the provisions of such notes; (v) the issue, in connection with the administration of a 50 for 1 reverse share split on November 24, 2022, of 4 ADSs; (vi) the sale of 155,000 ADSs and pre-funded Warrants for 1,315,000 ADSs in November 2022, (vii) the issue of Series A Ordinary Warrants to purchase up to 1,470,000 ADSs and Series B Ordinary Warrants to purchase up to 1,470,000 ADSs and Representative Warrants to purchase up to 110,250 ADS in the November 2022 Financing; (viii) the subsequent exercise of pre-funded Warrants for 1,315,000 ADSs during January 2023; (ix) the amendment to reflect that certain existing warrants to purchase up to an aggregate of 2,800,000 ADSs of the Company that were previously issued on November 30, 2022, at an exercise price of $5.00 per ADS and expiration dates of May 30, 2025 and May 30, 2028, will be amended effective upon the closing of the offering so that the amended warrants will have a reduced exercise price of $1.75 per ADS; (x) the movement in the fair value of the Warrants outstanding as at March 27, 2023; and (xi) the sale of 215,000 ADSs and pre-funded Warrants for 3,222,500 ADSs and 3,437,500 Series C Ordinary Warrants pursuant to this prospectus at a public offering price of $1.60 per one ADS and accompanying warrant in this offering and after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value at June 30, 2022 would have been $7.2 million, or £5.9 million and $2.90 per share, or £2.38 per share. This represents an immediate decrease in pro forma as adjusted net tangible book value of $0.13 per ordinary share to existing investors and immediate dilution of ($1.30) per ADS to new investors attributable to this offering. The following table illustrates this dilution to new investors purchasing ADSs in this offering:

The number of our ordinary shares (including shares represented by ADSs) to be outstanding after this offering is based on 2,264,958 ordinary shares outstanding as of March 27, 2023 and excludes:

Unless otherwise stated, all information in this prospectus assumes no exercise of the outstanding options described above into ordinary shares or ADSs, treats all restricted shares issued with outstanding restrictions to be vested as issued and outstanding shares, no exercise of the Series C Ordinary Warrants or of the Placement Agent Warrants issued in this offering and no sale of pre-funded warrants in this offering.

MATERIAL INCOME TAX CONSIDERATIONS

The following summary contains a description of material U.K. and U.S. federal income tax consequences of the acquisition, ownership and disposition of our ordinary shares. This summary should not be considered a comprehensive description of all the tax considerations that may be relevant to the decision to acquire our ordinary shares.

U.S. Federal Income Taxes

The following is a summary of the material U.S. federal income tax consequences to U.S. Holders (as defined below) of purchasing, owing and disposing of the ordinary shares or ADSs. This discussion is included for general informational purposes only, does not purport to consider all aspects of U.S. federal income taxation that might be relevant to a U.S. Holder, and does not constitute, and is not, a tax opinion for or tax advice to any particular U.S. Holder of ordinary shares or the ADSs. The summary does not address any U.S. tax matters other than those specifically discussed. The summary is based on the provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), existing, temporary and proposed Treasury Regulations issued thereunder, judicial decisions and administrative rulings and pronouncements and other legal authorities, all as of the date hereof and all of which are subject to change, possibly with retroactive effect. Any such change could alter the tax consequences described herein.

The discussion below applies only to U.S Holders as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment), and does not address the tax consequences that may be relevant to U.S. Holders who, in light of their particular circumstances, may be subject to special tax rules, including without limitation:

Any such U.S. Holders should consult their own tax advisors.

For purposes of this discussion, a “U.S. Holder” means a holder of our ordinary shares or ADSs that is or is treated as, for U.S. federal income tax purposes,

If a partnership or other pass-through entity (including any entity or arrangement treated as such for purposes of U.S. federal income tax law) holds our ordinary shares or ADSs, the tax treatment of a partner of such partnership or member of such entity will generally depend upon the status of the partner and the activities of the partnership. Partnerships and other pass-through entities holding our ordinary shares or ADSs, and any person who is a partner or member of such entities should consult their own tax advisors regarding the tax consequences of purchasing, owning and disposing of the ordinary shares or ADSs.

Passive Foreign Investment Company Considerations

A non-U.S. corporation, such as TCB, will be classified as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes, if, in the case of any particular taxable year, either (i) 75% or more of its gross income for such taxable year consists of certain types of “passive” income or (ii) 50% or more of the value of its assets (based on an average of the quarterly values of the assets) during such taxable year is attributable to assets that produce or are held for the production of passive income. For this purpose, cash is categorized as a passive asset and the company’s un-booked intangibles associated with active business activities may generally be classified as active assets. Passive income generally includes, among other things, dividends, interest, rents, royalties, and gains from the disposition of passive assets. For this purpose, a foreign corporation will be treated as owning its proportionate share of the assets and earning its proportionate share of the income of any other non-U.S. corporation in which it owns, directly or indirectly, more than 25% (by value) of the stock.

Based upon its current income and assets and projections as to the value of the ordinary shares or ADSs, it is not presently expected that we will be classified as a PFIC for the 2022 taxable year or the foreseeable future.

The determination of whether we will be or become a PFIC will depend upon the composition of its income (which may differ from our historical results and current projections) and assets and the value of its assets from time to time, including, in particular the value of its goodwill and other un-booked intangibles (which may depend upon the market value of the ordinary shares or ADSs from time to time and may be volatile). Among other matters, if our market capitalization is less than anticipated or subsequently declines, we may be classified as a PFIC for the taxable year in the 2021 taxable year or future taxable years. It is also possible that the IRS may challenge the classification or valuation of our assets, including its goodwill and other unbooked intangibles, or the classification of certain amounts received by us, including interest earnings, which may result in our being, or becoming classified as, a PFIC for the taxable year in 2021 or future taxable years.

The determination of whether we will be or become a PFIC may also depend, in part, on how, and how quickly, it uses liquid assets and the cash proceeds of this offering or otherwise. If we were to retain significant amounts of liquid assets, including cash, the risk of our being classified as a PFIC may substantially increase. Because there are uncertainties in the application of the relevant rules and PFIC status is a factual determination made annually after the close of each taxable year, there can be no assurance that we will not be a PFIC for the 2022 taxable year or any future taxable year, and no opinion of counsel has or will be provided regarding the classification of us as a PFIC. If we were classified as a PFIC for any year during which a holder held our ordinary shares or ADSs, it generally would continue to be treated as a PFIC for all succeeding years during which such holder held the ordinary shares or ADSs. The discussion below under “—Dividends Paid on Ordinary Shares or ADSs” and “—Sale or Other Disposition of Ordinary Shares or ADS” is written on the basis that we will not be classified as a PFIC for U.S. federal income tax purposes.

Dividends Paid on Ordinary Shares including ordinary shares represented by ADSs

Subject to the PFIC rules described below, any cash distributions (including constructive distributions) paid on the ordinary shares including ordinary shares represented by ADSs out of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles, will generally be includible in the gross income of a U.S. Holder as dividend income on the day actually or constructively received by the U.S. Holder, in the case of ordinary shares including ordinary shares represented by ADSs. Because we do not intend to determine our earnings and profits on the basis of U.S. federal income tax principles, any distribution will generally be treated as a “dividend” for U.S. federal income tax purposes. Under current law, a non-corporate recipient of a dividend from a “qualified foreign corporation” will generally be subject to tax on the dividend income at the lower applicable net capital gains rate rather than the marginal tax rates generally applicable to ordinary income provided that certain holding period and other requirements are met.

A non-U.S. 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) will generally be considered to be a qualified foreign corporation (i) if it is eligible for the benefits of a comprehensive tax treaty with the United States which the Secretary of Treasury of the United States determines is satisfactory for these purposes and which includes an exchange of information program, or (ii) with respect to any dividend paid by such corporation on its stock, if such stock is readily tradable on an established securities market in the United States. We believe we are eligible for the benefits of the Convention Between the Government of the United States of America and the Government of the United Kingdom of Great Britain and Northern Ireland for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and On Capital Gains, or the United States-United Kingdom income tax treaty (which the Secretary of the Treasury of the United States has determined is satisfactory for this purpose and includes an exchange of information program), in which case it would be treated as a qualified foreign corporation with respect to dividends paid on the ordinary shares or ADSs. U.S. Holders are urged to consult their tax advisors regarding the availability of the reduced tax rate on dividends in their particular circumstances. Dividends received on the ordinary shares will not be eligible for the dividends received deduction allowed to corporations.

Sale or Other Disposition of Ordinary Shares or ADSs

Subject to the PFIC rules discussed below, a U.S. Holder of our ordinary shares or ADSs will generally recognize capital gain or loss, if any, upon the sale or other disposition of ordinary shares or ADSs, respectively, in an amount equal to the difference between the amount realized upon the disposition and the U.S. Holder’s adjusted tax basis in such ordinary shares or ADSs. Any capital gain or loss will be long-term capital gain or loss if the ordinary shares or ADSs have been held for more than one year and will generally be United States source capital gain or loss for United States foreign tax credit purposes. Long-term capital gains of non-corporate taxpayers are currently eligible for reduced rates of taxation.

Disposition of Foreign Currency

U.S. Holders are urged to consult their tax advisors regarding the tax consequences of receiving, converting or disposing of any non-U.S. currency received as dividends on our ordinary shares or ADSs.

Tax on Net Investment Income

A U.S. Holder may be subject to a Medicare surtax of 3.8% on some or all of such U.S. Holder’s “net investment income” as defined in Section 1411 of the Code. Net investment income generally includes income from the ordinary shares or ADSs unless such income is derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). You should consult your tax advisors regarding the effect this Medicare tax may have, if any, on your acquisition, ownership or disposition of ordinary shares or ADSs.

Passive Foreign Investment Company Rules

If we are is classified as a PFIC for any taxable year during which a U.S. Holder holds our ordinary shares or ADSs, unless the holder makes a mark-to-market election (as described below), the holder will, except as discussed below, be subject to special tax rules that have a penalizing effect, regardless of whether we remain a PFIC, on (i) any excess distribution that we make to the holder (which generally means any distribution paid during a taxable year to a holder that is greater than 125% of the average annual distributions paid in the three preceding taxable years or, if shorter, the holder’s holding period for the ordinary shares or ADSs), and (ii) any gain realized on the sale or other disposition, including, under certain circumstances, a pledge, of our ordinary shares or ADSs. Under the PFIC rules:

If we are a PFIC for any taxable year during which a U.S. Holder holds our ordinary shares or ADSs and any of its non-U.S. subsidiaries is also a PFIC, such holder would be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC for purposes of the application of these rules. Each U.S. Holder is advised to consult its tax advisors regarding the application of the PFIC rules to any of our subsidiaries.

As an alternative to the foregoing rules, a U.S. Holder of “marketable stock” in a PFIC may make a mark-to-market election with respect to such ordinary shares or ADSs, provided that they are “regularly traded” (as specially defined under the Code) on The Nasdaq Stock Market. No assurances may be given regarding whether the ordinary shares or ADSs will qualify, or will continue to be qualified, as being regularly traded in this regard. If a mark-to-market election is made, the U.S. Holder will generally (i) include as ordinary income for each taxable year that we are a PFIC the excess, if any, of the fair market value of ordinary shares or ADSs held at the end of the taxable year over the adjusted tax basis of such securities and (ii) deduct as an ordinary loss the excess, if any, of the adjusted tax basis of such securities over the fair market value of such securities held at the end of the taxable year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. The U.S. Holder’s adjusted tax basis in the ordinary shares or ADSs would be adjusted to reflect any income or loss resulting from the mark-to-market election. If a U.S. Holder makes an effective mark-to-market election, in each year that we are a PFIC any gain recognized upon the sale or other disposition of the ordinary shares or ADSs will be treated as ordinary income and loss will be treated as ordinary loss, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. U.S. Holders of our ordinary shares or ADSs should consult their tax advisors regarding the availability of a mark-to-market election with respect to such ordinary shares or ADSs.

If a U.S. Holder makes a mark-to-market election in respect of a corporation classified as a PFIC and such corporation ceases to be classified as a PFIC, the holder will not be required to take into account the mark-to-market gain or loss described above during any period that such corporation is not classified as a PFIC.

Because a mark-to-market election cannot be made for any lower-tier PFICs that a PFIC may own, a U.S. Holder who makes a mark-to-market election with respect to the ordinary shares or ADSs may continue to be subject to the general PFIC rules with respect to such holder’s indirect interest in any of our non-U.S. subsidiaries that is classified as a PFIC.

We do not intend to provide information necessary for U.S. Holder’s to make qualified electing fund elections, which, if available, would result in tax treatment different from the general tax treatment for PFICs described above. However, as described above under “Passive Foreign Investment Company Considerations-PFIC Classification of TCB,” it is not presently expected that we will be classified as a PFIC for the 2022 taxable year or the foreseeable future.

As discussed above under “Dividends Paid on Ordinary Shares or ADSs”, dividends that we pay on the ordinary shares or ADSs will not be eligible for the reduced tax rate that applies to qualified dividend income if we are is classified as a PFIC for the taxable year in which the dividend is paid or the preceding taxable year. In addition, if a U.S. Holder owns the ordinary shares or ADSs during any taxable year that we are a PFIC, the holder must file an annual information return with the IRS. Each holder is urged to consult its tax advisor concerning the U.S. federal income tax consequences of purchasing, holding, and disposing ordinary shares or ADSs if we are or become a PFIC, including the possibility of making a mark-to-market election and the unavailability of the qualified electing fund election.

Information reporting and backup withholding

Certain U.S. Holders are required to report information to the IRS relating to an interest in “specified foreign financial assets,” including shares issued by a non-U.S. corporation, for any year in which the aggregate value of all specified foreign financial assets exceeds $50 thousand (or a higher U.S. dollar amount prescribed by the IRS), subject to certain exceptions (including an exception for shares held in custodial accounts maintained with a United States financial institution). These rules also impose penalties if a holder is required to submit such information to the IRS and fails to do so.

In addition, U.S. Holders may be subject to information reporting to the IRS and backup withholding with respect to dividends on and proceeds from the sale or other disposition of our ordinary shares or ADSs. Information reporting will apply to payments of dividends on, and to proceeds from the sale or other disposition of, our ordinary shares or ADSs by a paying agent within the United States to a holder, other than holders that are exempt from information reporting and properly certify their exemption. A paying agent within the United States will be required to withhold at the applicable statutory rate, currently 24%, in respect of any payments of dividends on, and the proceeds from the disposition of, our ordinary shares or ADSs within the U.S. to a U.S. Holder (other than holders that are exempt from backup withholding and properly certify their exemption) if the holder fails to furnish its correct taxpayer identification number or otherwise fails to comply with applicable backup withholding requirements. U.S. Holders who are required to establish their exempt status generally must provide a properly completed IRS Form W-9.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a holder’s U.S. federal income tax liability. A U.S. Holder generally may obtain a refund of any amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the IRS in a timely manner and furnishing any required information. Each U.S. Holder is advised to consult with its tax advisor regarding the application of the United States information reporting rules to their particular circumstances.

Material United Kingdom Tax Considerations

The following is a description of the material U.K. tax considerations relating primarily to the ownership and disposal of our ordinary shares or ADSs by the U.S. Holders described above. The U.K. tax comments set out below are based on current U.K. tax law as applied in Scotland, and HMRC practice (which may not be binding on HMRC) as at the date of this summary, both of which are subject to change, possibly with retrospective effect. They are intended as a general guide and, save where otherwise stated, only apply to you if you are not resident in the U.K. for U.K. tax purposes and do not hold our ordinary shares or ADSs for the purposes of a trade, profession or vocation that you carry on in the U.K. through a branch, agency or permanent establishment in the U.K. and if you hold our ordinary shares as an investment for U.K. tax purposes and are not subject to special rules.

This summary does not address all possible tax consequences relating to an investment in our ordinary shares or ADSs. In particular it does not cover the U.K. inheritance tax consequences of holding our ordinary shares or ADSs. It assumes that the depositary or DTC has not made an election under section 97A(1) of the Finance Act 1986. It assumes that we do not (and will not at any time) derive 75% or more of our qualifying asset value, directly or indirectly, from U.K. land, and that we are and remain solely resident in the U.K. for tax purposes. It assumes that the holder is not our officer or our employee (or of any related company of ours) and has not (and is not deemed to have) acquired the ordinary shares or ADSs by virtue of an office or employment. It assumes that a holder of ordinary shares or ADSs is the beneficial owner of the underlying ordinary shares for U.K. tax purposes. This summary is for general information only and is not intended to be, nor should it be considered to be, legal or tax advice to any particular holder. Holders of our ordinary shares or ADSs are strongly urged to consult their tax advisers in connection with the U.K. tax consequences of their investment in our securities.

U.K. Taxation of Dividends and Distributions

We will not be required to withhold amounts for or on account of U.K. tax at source when paying a dividend or distribution in respect of our ordinary shares.

Individual holders who hold our ordinary shares as an investment, who are not resident in the U.K. for U.K. tax purposes should not be subject to U.K. income tax in respect of any dividends on our ordinary shares, unless they hold their ordinary shares in connection with any trade, profession or vocation carried on (whether solely or in partnership) by them in the U.K. through a branch, agency or permanent establishment in the U.K.. In these circumstances, such holder may, depending on his or her individual circumstances, be chargeable to U.K. income tax in respect of our dividends.

Corporate holders which are not resident in the U.K. for U.K. tax purposes should not be subject to U.K. corporation tax in respect of any dividends on our ordinary shares, unless they carry on a trade in the U.K. through a permanent establishment to which the ordinary shares are attributable. In these circumstances, such holders may, depending on their individual circumstances and if an exemption from U.K. corporation tax in respect of dividend payments does not apply, be chargeable to U.K. corporation tax in respect of our dividends.

U.K. Taxation of Capital Gains

An individual holder who is not resident in the U.K. for U.K. tax purposes should not be liable to U.K. capital gains tax on capital gains realized on the disposal of their ordinary shares unless such holder carries on (whether solely or in partnership) a trade, profession or vocation in the U.K. through a branch or agency in the U.K. to which our ordinary shares are attributable. In these circumstances, such holder may, depending on his or her individual circumstances, be chargeable to U.K. capital gains tax on chargeable gains arising from a disposal of his or her ordinary shares.

Any such individual holder of our ordinary shares who is temporarily non-resident for U.K. tax purposes will, in certain circumstances, become liable to U.K. tax on capital gains in respect of gains realized while they were not resident in the U.K.

A corporate holder of our ordinary shares which is not resident in the U.K. for U.K. tax purposes should not be liable for U.K. corporation tax on chargeable gains realized on the disposal of our ordinary shares unless it carries on a trade in the U.K. through a permanent establishment in the U.K. to which our ordinary shares are attributable. In these circumstances, a disposal of ordinary shares by such holder may give rise to a chargeable gain or an allowable loss for the purposes of U.K. corporation tax.

Stamp Duty and Stamp Duty Reserve Tax

The discussion below relates to the holders of our ordinary shares or ADSs wherever resident, however it should be noted that special rules may apply to certain persons such as market makers, brokers, dealers or intermediaries.

As a general rule (and except in relation to depositary receipt systems and clearance services (as to which see below)), no UK stamp duty or stamp duty reserve tax, or SDRT, is payable on the issue of the ordinary shares underlying the ADSs.

An unconditional agreement to transfer ordinary shares will normally give rise to a charge to SDRT at the rate of 0.5% of the amount or value of the consideration payable for the transfer. The purchaser of the shares is liable for the SDRT. Transfers of ordinary shares in certificated form are generally also subject to stamp duty at the rate of 0.5% of the amount or value of the consideration given for the transfer (rounded up to the next £5.00). Stamp duty is normally paid by the purchaser. The charge to SDRT will be cancelled or, if already paid, repaid (generally with interest), where a transfer instrument has been duly stamped within six years of the charge arising, (either by paying the stamp duty or by claiming an appropriate relief) or if the instrument is otherwise exempt from stamp duty.

Under current UK legislation, an issue or transfer of ordinary shares or an unconditional agreement to transfer ordinary shares to a clearance service or a depositary receipt system (including to a nominee or agent for, a person whose business is or includes the issue of depositary receipts or the provision of clearance services) will generally be subject to SDRT (and, in the case of transfers, where the transfer is effected by a written instrument, stamp duty) at a higher rate of 1.5% of the amount or value of the consideration given for the transfer or, in certain circumstances, the value of the ordinary shares unless the clearance service has made and maintained an election under section 97A of the UK Finance Act 1986, or a section 97A election. It is understood that HMRC regards the facilities of DTC as a clearance service for these purposes and we are not aware of any section 97A election having been made by the DTC.

However, based on current published HMRC practice following European Union case law in respect of the European Council Directives 69/335/EEC and 2009/7/EC, no SDRT is generally payable in respect of such an issue of ordinary shares and no SDRT or stamp duty is generally payable in respect of such a transfer of ordinary shares where such transfer is an integral part of an issue of share capital. It is noted that on January 31, 2020 the United Kingdom ceased to be a Member State of the European Union. Accordingly, the extent to which HMRC’s position will remain as set out in this paragraph following the end of the transition period on December 31, 2020 is uncertain.

Any stamp duty or SDRT payable on an issue or transfer of ordinary shares to a depositary receipt system or clearance service (although strictly accountable by the clearance service or depositary receipt system operator or their nominee) will in practice generally be paid by the transferors or participants in the clearance service or depositary receipt system. Specific professional advice should be sought before incurring or reimbursing the costs of a 1.5% stamp duty or SDRT charge in any circumstances.

No UK SDRT or stamp duty is required to be paid in respect of the issue or transfer of, or an agreement to transfer, ADSs (including by way of a paperless transfer of ADSs through the facilities of DTC).

Each ADS or pre-funded warrant is being sold together with a Series C Ordinary Warrant to purchase one ADS. The ADSs or pre-funded warrants and accompanying Warrants will be issued separately. We are also registering the ADSs issuable from time to time upon exercise of the Series C Ordinary Warrants and the pre-funded warrants offered hereby.

American Depositary Shares (‘ADSs’)

The description of our ADSs under the section “Share Capital” in our Annual Report on Form 20-F for the fiscal year ended December 31, 2021 is incorporated herein by reference.

Warrants

General

The following is a brief summary of certain terms and conditions of the warrants being offered by us. The following description is subject in all respects to the provisions contained in the form of warrant, the form of which will be filed as an exhibit to the registration statement of which this prospectus forms a part.

Duration and Exercise Price

The warrants offered hereby will have an exercise price of $1.75 per ADS. The warrants will be immediately exercisable and may be exercised at any time on or after the initial exercise date and on or before the five-year anniversary of the date of issuance. The exercise prices and numbers of ADSs issuable upon exercise are subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our ADSs. Warrants will be issued in certificated form only.

Exercisability

The warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of ADSs purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of such holder’s warrants to the extent that the holder would own more than 4.99% (or 9.99%, at the holder’s election) of our outstanding ADSs immediately after exercise, except that upon notice from the holder to us, the holder may decrease or increase the limitation of ownership of outstanding stock after exercising the holder’s warrants up to 9.99% of the number of ADSs outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the warrants, provided that any increase in such limitation shall not be effective until 61 days following notice to us.

Cashless Exercise

If, at the time a holder exercises its warrants, a registration statement registering the issuance of the ADSs underlying the warrants under the Securities Act, is not then effective or available for the issuance of such ADSs, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of ADSs determined according to a formula set forth in the warrant.

Transferability

A warrant may be transferred at the option of the holder upon surrender of the warrant to us together with the appropriate instruments of transfer.

Fractional ADSs

No fractional ADSs will be issued upon the exercise of the warrants. Rather, the number of ADSs to be issued will, at our election, either be rounded up to the nearest whole number or we will pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

Trading Market

There is no established trading market for any of the warrants, and we do not expect a market to develop. We do not intend to apply for a listing for any of the warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the warrants will be limited.

Rights as a Shareholder

Except as otherwise provided in the warrants or by virtue of the holders’ ownership of ADSs, the holders of warrants do not have the rights or privileges of holders of our ADSs, including any voting rights, until such warrant holders exercise their warrants.

Fundamental Transaction

In the event of a fundamental transaction, as described in the warrants and generally including any reorganization, recapitalization or reclassification of our ADSs, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding ADSs, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding ADSs, the holders of the warrants will be entitled to receive upon exercise of the warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the warrants immediately prior to such fundamental transaction. In addition, in the event of a fundamental transaction which is approved by our Board, the holders of the Series C Ordinary Warrants have the right to require us or a successor entity to redeem the Series C Ordinary Warrants for cash in the amount of the Black-Scholes value of the unexercised portion of the Series C Ordinary Warrants on the date of the consummation of the fundamental transaction. In the event of a fundamental transaction which is not approved by our board of directors, the holders of the Series C Ordinary Warrants have the right to require us or a successor entity to redeem the Series C Ordinary Warrant for the consideration paid in the fundamental transaction in the amount of the Black-Scholes value of the unexercised portion of the Series C Ordinary Warrant on the date of the consummation of the fundamental transaction.

Waivers and Amendments

No term of the warrants may be amended or waived without the written consent of the holder of such warrant.

Pre-Funded Warrants

General

The term “pre-funded” refers to the fact that the purchase price of the pre-funded warrants in this offering includes almost the entire exercise price that will be paid under the pre-funded warrants, except for a nominal remaining exercise price of $0.001. The purpose of the pre-funded warrants is to enable investors that may have restrictions on their ability to beneficially own more than 4.99% (or, at the election of such purchaser, 9.99%) of our outstanding ADSs following the consummation of this offering the opportunity to invest capital into the Company without triggering their ownership restrictions, by receiving pre-funded warrants in lieu of ADSs which would result in such ownership of more than 4.99% or 9.99%, as applicable, and receiving the ability to exercise their option to purchase the ADSs underlying the pre-funded warrants at a nominal price at a later date.

The following is a brief summary of certain terms and conditions of the pre-funded warrants being offered by us. The following description is subject in all respects to the provisions contained in the form of pre-funded warrant, the form of which will be filed as an exhibit to the registration statement of which this prospectus forms a part.

Exercise Price

Pre-funded warrants will have an exercise price of $0.001 per ADSs. The exercise price is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our ADSs and also upon any distributions of assets, including cash, stock or other property to our stockholders.

Exercisability

The pre-funded warrants are exercisable at any time after their original issuance and until exercised in full. The pre-funded warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and by payment in full of the exercise price in immediately available funds for the number of ADSs purchased upon such exercise. As an alternative to payment in immediately available funds, the holder may elect to exercise the pre-funded warrant through a cashless exercise, in which the holder would receive upon such exercise the net number of ADSs determined according to the formula set forth in the pre-funded warrant. No fractional ADSs will be issued in connection with the exercise of a pre-funded warrant.

Exercise Limitations

The pre-funded warrants may not be exercised by the holder to the extent that the holder, together with its affiliates, would beneficially own, after such exercise more than 4.99% of the ADSs then outstanding (including for such purpose the ADSs issuable upon such exercise). However, any holder may increase or decrease such beneficial ownership limitation upon notice to us, provided that such limitation cannot exceed 9.99%, and provided that any increase in the beneficial ownership limitation shall not be effective until 61 days after such notice is delivered. Purchasers of pre-funded warrants in this offering may also elect prior to the issuance of the pre-funded warrants to have the initial exercise limitation set at 9.99% of our outstanding ADSs.

Transferability

Subject to applicable laws, the pre-funded warrants may be offered for sale, sold, transferred or assigned without our consent.

Exchange Listing

There is no established trading market for the pre-funded warrants and we do not expect a market to develop. In addition, we do not intend to apply for the listing of the pre-funded warrants on any national securities exchange or other trading market. Without an active trading market, the liquidity of the pre-funded warrants will be limited.

Fundamental Transactions

In the event of a fundamental transaction, as described in the pre-funded warrants and generally including any reorganization, recapitalization or reclassification of our ADSs, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding ADSs, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding ADSs, upon consummation of such a fundamental transaction, the holders of the pre-funded warrants will be entitled to receive upon exercise of the pre-funded warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the pre-funded warrants immediately prior to such fundamental transaction without regard to any limitations on exercise contained in the pre-funded warrants.

Rights as a Shareholder

Except as otherwise provided in the pre-funded warrant or by virtue of such holder’s ownership of shares of our ADSs, the holder of a pre-funded warrant does not have the rights or privileges of a holder of our ADSs, including any voting rights, until the holder exercises the pre-funded warrant. The pre-funded warrants will provide that holders have the right to participate in distributions or dividends paid on our ADSs.

Placement Agent Warrants

The following summary of certain terms and provisions of the Placement Agent Warrants that are being issued hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Placement Agent Warrants, the form of which will be filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of Placement Agent Warrant for a complete description of the terms and conditions of the Placement Agent Warrant.

Duration and Exercise Price

Each Placement Agent Warrant offered hereby will have an initial exercise price equal to $2.00 per ADS. The Placement Agent Warrants will be immediately exercisable and will expire five years from the commencement of sales in this offering. The exercise price and number of ADSs issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our ADSs and the exercise price.

Exercisability

The Placement Agent Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of ADSs purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the Placement Agent Warrant to the extent that the holder would own more than 4.99% of the outstanding ADSs immediately after exercise, except that upon notice from the holder to us, the holder may increase or decrease the amount of beneficial ownership of outstanding stock after exercising the holder’s Placement Agent Warrant up to 4.99% of the number of ADSs outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Placement Agent Warrants and in accordance with the rules and regulations of the SEC, provided that any increase in the beneficial ownership limitation shall not be effective until 61 days following notice to us.

Cashless Exercise

If, at the time a holder exercises its Placement Agent Warrants, a registration statement registering the issuance of the ADSs underlying the Placement Agent Warrants under the Securities Act is not then effective or available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of ADSs determined according to a formula set forth in the Placement Agent Warrants.

Fractional ADSs

No fractional ADSs will be issued upon the exercise of the Placement Agent Warrants. Rather, the number of ADSs to be issued will be rounded up to the next whole share or we will pay a cash adjustment equal to such fraction multiplied by the exercise price to the holder.

Transferability

Subject to applicable laws, a Placement Agent Warrant may be transferred at the option of the holder upon surrender of the Placement Agent Warrant to us together with the appropriate instruments of transfer.

Trading Market

There is no trading market available for the Placement Agent Warrants on any securities exchange or nationally recognized trading system, and we do not expect a trading market to develop. We do not intend to list the Placement Agent Warrants on any securities exchange or other trading market. Without a trading market, the liquidity of the Placement Agent Warrants will be extremely limited. The ADSs issuable upon exercise of the Placement Agent Warrants is currently listed on the Nasdaq Capital Market.

Right as a Shareholder

Except as otherwise provided in the Placement Agent Warrants or by virtue of such holder’s ownership of ADSs, the holders of the Placement Agent Warrants do not have the rights or privileges of holders of our ADSs, including any voting rights, until they exercise their Placement Agent Warrants.

Fundamental Transaction

In the event of a fundamental transaction, as described in the Placement Agent Warrants and generally including any reorganization, recapitalization or reclassification of our ADSs, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding ADSs, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding ADSs, the holders of the Placement Agent Warrants will be entitled to receive upon exercise of the Placement Agent Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Placement Agent Warrants immediately prior to such fundamental transaction. In addition, in the event of a fundamental transaction which is approved by our board of directors, the holders of the Placement Agent Warrants have the right to require us or a successor entity to redeem the Placement Agent Warrant for cash in the amount of the Black-Scholes value of the unexercised portion of the Placement Agent Warrant on the date of the consummation of the fundamental transaction. In the event of a fundamental transaction which is not approved by our board of directors, the holders of the Placement Agent Warrants have the right to require us or a successor entity to redeem the Placement Agent Warrants for the consideration paid in the fundamental transaction in the amount of the Black Scholes value of the unexercised portion of the Placement Agent Warrant on the date of the consummation of the fundamental transaction.

PLAN OF DISTRIBUTION

We have engaged H.C. Wainwright & Co., LLC, or the placement agent, to act as our exclusive placement agent to solicit offers to purchase the securities offered pursuant to this prospectus on a reasonable best efforts basis. The engagement agreement does not give rise to any commitment by the placement agent to purchase any of our securities, and the placement agent will have no authority to bind us by virtue of the engagement agreement. The placement agent is not purchasing or selling any of the securities offered by us under this prospectus, nor is it required to arrange for the purchase or sale of any specific number or dollar amount of securities, other than to use its “reasonable best efforts” to arrange for the sale of such securities by us. Therefore, we may not sell all of the securities being offered. The terms of this offering were subject to market conditions and negotiations between us, the placement agent and prospective investors. This is a best efforts offering and there is no minimum offering amount required as a condition to the closing of this offering. The placement agent does not guarantee that it will be able to raise new capital in any prospective offering. The placement agent may engage sub-agents or selected dealers to assist with the offering.

Investors purchasing securities offered hereby will have the option to execute a securities purchase agreement with us. In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers which enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The ability to pursue a claim for breach of contract is material to larger purchasers in this offering as a means to enforce the following covenants uniquely available to them under the securities purchase agreement: (i) a covenant to not enter into variable rate financings for a period of one (1) year following the closing of the offering, subject to certain exceptions; and (ii) a covenant to not enter into any equity financings for sixty (60) days from closing of the offering, subject to certain exceptions.

The nature of the representations, warranties and covenants in the securities purchase agreements shall include:

We expect to deliver the securities being offered pursuant to this prospectus on or about March 30, 2023, subject to satisfaction of certain customary closing conditions.

Fees and Expenses

The following table shows the per ADS and per pre-funded warrant and accompanying warrant and total placement agent fees we will pay in connection with the sale of the securities in this offering.

We have agreed to pay the placement agent a cash fee equal to 7.5% of the gross proceeds raised in this offering and a management fee equal to 1.0% of the gross proceeds raised in this offering. In addition, we have agreed to pay the placement agent for its non-accountable expenses in the amount of $24,050, its legal fees and expenses and other out-of-pocket expenses in an amount up to $100,000, and its clearing expenses in the amount of $15,950. We estimate the total offering expenses of this offering that will be payable by us, excluding the placement agent fees and expenses, will be approximately $0.4 million.

Placement Agent Warrants

In addition, we have agreed to issue to the placement agent or its designees warrants to purchase up to 257,813 ADSs with an exercise price of $2.00 per ADS and exercisable for five years from the date of the commencement of sales in this offering. The placement agent warrants and underlying ADSs are registered on the registration statement of which this prospectus is a part. The form of the placement agent warrant has been included as an exhibit to this registration statement of which this prospectus forms a part. Pursuant to FINRA Rule 5110(e), the placement agent warrants and any ADSs issued upon exercise of the placement agent warrants shall not be sold, transferred, assigned, pledged, or hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of the securities by any person for a period of 180 days immediately following the date of commencement of sales of this offering, except the transfer of any security: (i) by operation of law or by reason of reorganization of the issuer; (ii) to any FINRA member firm participating in the offering and the officers, partners, registered persons or affiliates thereof, if all securities so transferred remain subject to the lock-up restriction set forth above for the remainder of the time period; (iii) if the aggregate amount of our securities held by the Representative or related persons does not exceed 1% of the securities being offered; (iv) that is beneficially owned on a pro-rata basis by all equity owners of an investment fund, provided that no participating member manages or otherwise directs investments by the fund and the participating members in the aggregate do not own more than 10% of the equity in the fund; (v) the exercise or conversion of any security, if all securities remain subject to the lock-up restriction set forth above for the remainder of the time period; (vi) if we meet the registration requirements of Forms S-3, F-3 or F-10; or (vii) back to us in a transaction exempt from registration with the SEC.

Tail

We have also agreed to pay the placement agent a tail fee equal to the cash and warrant compensation in this offering, if any investor, who was contacted or introduced to us by the placement agent during the term of its engagement, provides us with capital in any public or private offering or other financing or capital raising transaction during the one (1) year period following expiration or termination of our engagement of the placement agent.

Lock-up Agreements

We and each of our officers and directors have agreed with the placement agent to be subject to a lock-up period of sixty (60) days following the date of closing of the offering pursuant to this prospectus. This means that, during the applicable lock-up period, we and such persons may not offer for sale, contract to sell, sell, distribute, grant any option, right or warrant to purchase, pledge, hypothecate or otherwise dispose of, directly or indirectly, any of our ADSs or any securities convertible into, or exercisable or exchangeable for, ADSs, subject to customary exceptions. The placement agent may waive the terms of these lock-up agreements in its sole discretion and without notice. In addition, we have agreed to not issue any securities that are subject to a price reset based on the trading prices of our ADS or upon a specified or contingent event in the future, or enter into any agreement to issue securities at a future determined price for a period of one (1) year following the closing date of this offering, subject to an exception.

Regulation M

The placement agent may be deemed to be an underwriter within the meaning of Section 2(a)(11) of the Securities Act, and any commissions received by it and any profit realized on the resale of the securities sold by it while acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. As an underwriter, the placement agent would be required to comply with the requirements of the Securities Act and the Exchange Act, including, without limitation, Rule 10b-5 and Regulation M under the Exchange Act. These rules and regulations may limit the timing of purchases and sales of our securities by the placement agent acting as principal. Under these rules and regulations, the placement agent (i) may not engage in any stabilization activity in connection with our securities and (ii) may not bid for or purchase any of our securities or attempt to induce any person to purchase any of our securities, other than as permitted under the Exchange Act, until it has completed its participation in the distribution.

Indemnification

We have agreed to indemnify the placement agent against certain liabilities, including certain liabilities arising under the Securities Act, or to contribute to payments that the placement agent may be required to make for these liabilities.

Determination of Offering Price and Warrant Exercise Price

The actual offering price of the securities we are offering has been negotiated between us and the investors in the offering based on the trading of our ADSs prior to the offering, among other things. Other factors considered in determining the public offering price of the securities we are offering include our history and prospects, the stage of development of our business, our business plans for the future and the extent to which they have been implemented, an assessment of our management, the general conditions of the securities markets at the time of the offering and such other factors as were deemed relevant.

Electronic Offer, Sale and Distribution of Securities

A prospectus in electronic format may be made available on the websites maintained by the placement agent, if any, participating in this offering and the placement agent may distribute prospectuses electronically. Other than the prospectus in electronic format, the information on these websites is not part of this prospectus or the registration statement of which this prospectus forms a part, has not been approved or endorsed by us or the placement agent, and should not be relied upon by investors.
