PROSPECTUS

INTELLIGENT BIO SOLUTIONS INC.

6,896,550 Shares of Common Stock

Pursuant to this prospectus, the selling stockholders identified herein (the "Selling Stockholders") are offering on a resale basis an aggregate of 6,896,550 shares of our common stock.

The 6,896,550 shares of common stock offered for resale hereby were acquired by the Selling Stockholders in a private placement transaction pursuant to a securities purchase agreement by and among us and the Selling Stockholders, dated December 31, 2025 (the "Purchase Agreement"), of which (i) 105,000 shares of our common stock (the "Shares") are outstanding and held by the Selling Stockholders, (ii) 2,193,850 shares of common stock are issuable upon exercise of our Series L Pre-Funded Common Stock Purchase Warrants (the "Pre-Funded Warrants") held by the Selling Stockholders, (iii) 2,298,850 shares of common stock are issuable upon exercise of our Series K-1 Common Stock Purchase Warrants (the "Series K-1 Warrants") held by the Selling Stockholders, and (iv) 2,298,850 shares of common stock are issuable upon exercise of our Series K-2 Common Stock Purchase Warrants (the "Series K-2 Warrants") held by the Selling Stockholders. See "Prospectus Summary - Private Placement of Shares of Common Stock and Warrants" for additional information regarding the private placement transaction and the Purchase Agreement.

The Pre-Funded Warrants, the K-1 Warrants, and the K-2 Warrants are referred to collectively herein as the "Warrants". We are registering the Shares and the shares of common stock issuable upon exercise of the Warrants on behalf of the Selling Stockholders, to be offered and sold by the Selling Stockholders from time to time.

We are not selling any shares of common stock under this prospectus and will not receive any proceeds from the sale by the Selling Stockholders of such shares. Upon any exercise of the Warrants by payment of cash, however, we will receive the exercise price of the Warrants. We intend to use those proceeds, if any, for working capital and general corporate purposes.

Sales of the shares by the Selling Stockholders may occur at fixed prices, at market prices prevailing at the time of sale, at prices related to prevailing market prices, at negotiated prices and/or at varying prices determined at the time of sale. The Selling Stockholders may sell shares directly or to or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the Selling Stockholders, the purchasers of the shares, or both. The Selling Stockholders may sell any, all or none of the securities offered by this prospectus and we do not know when or in what amount the Selling Stockholders may sell their shares of common stock hereunder following the effective date of the registration statement of which this prospectus forms a part. We provide more information about how the Selling Stockholders may sell or otherwise dispose of their shares of common stock in the section titled "Plan of Distribution" on page 11.

We are paying the cost of registering the shares of common stock covered by this prospectus as well as various related expenses. Each Selling Stockholder is responsible for all selling commissions, transfer taxes and other costs related to the offer and sale of its shares.

Our common stock is listed on the Nasdaq Capital Market and traded under the symbol "INBS." On January 20, 2026, the closing price of our common stock, as reported on the Nasdaq Capital Market was $13.81 per share. There is no established public trading market for the Series K-1 Warrants or Series K-2 Warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the Series K-1 Warrants or Series K-2 Warrants on any national securities exchange.

We are an "emerging growth company" as defined in Section 2(a) of the Securities Act and we have elected to comply with certain reduced public company reporting requirements.

You should read this prospectus, together with additional information described under the headings "Incorporation of Certain Information by Reference" and "Where You Can Find More Information," carefully before you invest in any of our securities.

Investing in our securities involves a high degree of risk. See the section entitled "Risk Factors" beginning on page 6 of this prospectus for a discussion of risks that should be considered in connection with an investment in our securities.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus is January 21, 2026

Overview of our Company

Intelligent Bio Solutions Inc. and its wholly owned Delaware subsidiary, GBS Operations Inc., were each formed on December 5, 2016, under the laws of the state of Delaware. Our Australian subsidiary, Intelligent Bio Solutions (APAC) Pty Ltd, was formed on August 4, 2016, under the laws of New South Wales, Australia and was renamed to Intelligent Bio Solutions (APAC) Pty Ltd on January 6, 2023. On October 4, 2022, INBS acquired Intelligent Fingerprinting Limited ("IFP"), a company registered in England and Wales (the "IFP Acquisition"). Our headquarters are in New York City.

Intelligent Bio Solutions Inc. is a medical technology company focused on developing and delivering intelligent, rapid, non-invasive testing and screening solutions. We operate globally with the objective of providing innovative and accessible solutions that improve the quality of life.

Our Testing Platforms

Intelligent Fingerprinting Platform. Our current active product is the Intelligent Fingerprinting Platform, which consists of the proprietary portable platform that analyzes fingerprint sweat using a one-time cartridge and portable handheld reader. The flagship product from this platform, which is commercially available in certain countries outside of the United States, is the Intelligent Fingerprinting Drug Screening System (the "IFP System" or "IFP Products"), a two-part system that consists of non-invasive, fingerprint sweat-based diagnostic testing products designed to detect drugs of abuse including opiates, cocaine, methamphetamines, benzodiazepines, cannabis, methadone, and buprenorphine. The IFP System comprises a small, tamper-evident drug screening cartridge onto which ten fingerprint sweat samples are collected in under a minute before the portable analysis unit provides an on-screen result in under ten minutes. Samples collected with a confirmatory kit can also be sent to a third-party laboratory service provider for confirmation testing. Customers include safety-critical industries such as construction, transportation and logistics, mining, manufacturing, engineering, drug treatment organizations in the rehabilitation sector, and judicial organizations.

We plan to bring the IFP System to new markets and grow within existing markets concentrating on:

	●	increasing market share across the United Kingdom and mainland Europe;
	●	commencing sales and distribution throughout Australia, New Zealand and other countries in the Asia Pacific Region ("APAC Region"), and establishing the infrastructure and satisfying the regulatory requirements needed to do so;
	●	continue to work on an updated 510(k) premarket notification for expansion into United States markets that require FDA clearance, followed by the planned initial launch of our opiate test system for codeine and then for additional drugs following such additional FDA clearance as may be required;
	●	initiating research aimed at broadening the capabilities of the IFP System to test for additional drugs and indications, facilitating the expansion of the platform into point-of-care medical testing;
	●	expanding the IFP System into new customer segments, including major sporting organizations, law enforcement, and commercial airlines; and
	●	developing a strategic network of distributors with established customer bases throughout the APAC Region, Europe and North America to distribute the IFP Products.

Biosensor Platform. Under the terms of an Amended and Restated License Agreement dated September 12, 2019 (the "BPT License Agreement"), between the Company and Life Science Biosensor Diagnostics Pty Ltd ("LSBD" or "Licensor"), we held an exclusive license in the APAC Region to the Licensor's proprietary rights to the biosensor technology (the "Biosensor IP") used in the biosensor platform we refer to as the Biosensor Platform Technology ("BPT"), or simply the "Biosensor Platform". This platform consists of a small, printable modified organic thin-film transistor strip designed to detect multiple biological analytes by substituting the top enzyme layer of the biosensor to suit each analyte. We refer to products that use the BPT as the "Licensed Products". This platform technology has the potential to develop a range of Point of Care Tests. We understand that following the commencement of the liquidation of LSBD on July 21, 2023, the intellectual property we licensed from LSBD (the "LSBD IP"), which includes the Biosensor IP, has reverted back to the University of Newcastle. Following our discussions with the University of Newcastle, it is our understanding that the University of Newcastle cannot finalize licensing of the LSBD IP until the liquidation, by virtue of the status of LSBD being under external administration, is completed. As of the date of this prospectus, the ASIC database maintained by the Australian Securities and Investments Commission (ASIC) indicates that LSBD (Australian Company Number 613 279 771) is under the status of a company being under external administration. We do not know the timeline for when LSBD's liquidation will be complete or when LSBD's status will change, and accordingly, we do not expect any updates or finalization of any license terms until this occurs. As a result, further development of the BPT has been postponed until we are able to finalize appropriate licensing arrangements related to the BPT. For more information regarding our licensing agreements with LSBD, see "Business-Technology License Agreements."

Our Products.

Intelligent Fingerprinting Drug Screening System

Our wholly owned subsidiary, Intelligent Fingerprinting Limited (IFP), is the developer and owner of our proprietary and commercially available portable drug screening system designed to detect common drugs of abuse through fingerprint sweat. The IFP System consists of a small, tamper-evident drug screening cartridge that collects ten fingerprint sweat samples, which are then analyzed in a portable handheld reader for precise on-screen results in minutes. This system eliminates the need for invasive and unpleasant urine, saliva, or blood collection to test for substance abuse. The ten samples are collected in under a minute before the portable analysis unit provides an on-screen result in under ten minutes. The IFP System is currently designed to detect opioids, cocaine, methamphetamines, benzodiazepines, cannabis, methadone, and buprenorphine. In addition, samples collected via confirmatory kits can be sent to a third-party laboratory service provider for confirmation testing.

Intelligent Fingerprinting Drug Screening System Functionality

The IFP System consists of single-use, tamper-evident Intelligent Fingerprinting Cartridges for sample collection and the Intelligent Fingerprinting DSR-Plus portable analysis unit. The cartridge is inserted into the DSR-Plus reader and, within 10 minutes, results are displayed, with options to print and save anonymized data for further use. Results can also be downloaded to a computer for, among other things and to the extent legally permissible, integration with employee medical records or general statistical analysis.

History and Background of the Intelligent Fingerprinting Drug Screening System

Founded in 2007, IFP is a spin-out company from the University of East Anglia (UEA) and is based in Cambridge, England. IFP developed and commercialized the patented Intelligent Fingerprinting DSR-Plus reader and cartridge system, which has been predominantly sold in the United Kingdom, mainland Europe and the Middle East. IFP continues to manufacture the cartridges for the IFP System in its factory in Cambridge, England.

Implications of Being an Emerging Growth Company

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

	●	being permitted to present only two years of audited financial statements, in addition to any required unaudited interim financial statements, with correspondingly reduced "Management's Discussion and Analysis of Financial Condition and Results of Operations" disclosure in this prospectus;
	●	not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended ("Sarbanes-Oxley Act");
	●	reduced disclosure obligations regarding executive compensation in our periodic reports, proxy statements and registration statements; and
	●	exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

We may use these provisions until the last day of our fiscal year following the fifth anniversary of the completion of our initial public offering in December 2020. However, if certain events occur prior to the end of such five-year period, including if we become a "large accelerated filer," our annual gross revenues exceed $1.235 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period. The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. As an emerging growth company, we intend to take advantage of an extended transition period for complying with new or revised accounting standards as permitted by The JOBS Act.

To the extent that we continue to qualify as a "smaller reporting company," as such term is defined in Rule 12b-2 under the Securities Exchange Act of 1934, after we cease to qualify as an emerging growth company, certain of the exemptions available to us as an emerging growth company may continue to be available to us as a smaller reporting company, including: (i) not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes Oxley Act; (ii) scaled executive compensation disclosures; and (iii) the requirement to provide only two years of audited financial statements, instead of three years.

Recent Developments

Private Placement of Shares of Common Stock and Warrants

On December 31, 2025, we entered into the Purchase Agreement with two healthcare focused institutional investors for the sale by the Company of (i) 2,298,850 shares of the Company common stock (or Pre-funded Warrants in lieu thereof), (ii) Series K-1 Warrants to purchase up to an aggregate of 2,298,850 shares of common stock, and (iii) Series K-2 Warrants to purchase up to an aggregate of 2,298,850 shares of common stock in a private placement offering. The Series K-2 Warrants, the Series K-1 Warrants, and Pre-Funded Warrants are collectively referred to herein as the "Warrants." The combined purchase price of one share of common stock (or one Pre-Funded Warrant) and accompanying Series K-1 Warrant and Series K-2 Warrant was $4.35. The 2025 Private Placement closed on January 2, 2026. At the closing of the 2025 Private Placement, 105,000 Shares were issued, and 2,193,850 Pre-Funded Warrants were issued.

Subject to certain ownership limitations, the Warrants are exercisable upon issuance. Each Pre-Funded Warrant is exercisable into one share of common stock at a price per share of $0.01 (as adjusted from time to time in accordance with the terms thereof) and may be exercised at any time until the Pre-Funded Warrants are exercised in full. Each Series K-1 Warrant and Series K-2 Warrant is exercisable into one share of common stock at a price per share of $4.10 (as adjusted from time to time in accordance with the terms thereof). The Series K-1 Warrants and Series K-2 Warrants each have a term of five years following the date a registration statement registering all warrant shares underlying the Series K-1 Warrants and Series K-2 Warrants is declared effective by the SEC.

The gross proceeds to the Company from the 2025 Private Placement were approximately $10.0 million, before deducting the placement agent's fees and other offering expenses, and excluding the proceeds, if any, from the cash exercise of the Warrants. We intend to use the net proceeds from the 2025 Private Placement for working capital and for general corporate purposes.

In connection with the Purchase Agreement, we entered into a Registration Rights Agreement and agreed to file by January 10, 2026, a resale registration statement (the "Resale Registration Statement") with the SEC covering all shares of common stock sold to investors and the shares of common stock issuable upon exercise of the Warrants, and to use our best efforts to cause the Resale Registration Statement to be declared effective no later than February 14, 2026. We are filing the registration statement of which this prospectus forms a part in order to fulfil this obligation.

The Shares, the Warrants, and the shares issuable upon exercise of the Warrants were sold and issued without registration under the Securities Act of 1933, as amended (the "Securities Act"), in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and Rule 506 of Regulation D promulgated under the Securities Act as sales to accredited investors, and in reliance on similar exemptions under applicable state laws.

On December 31, 2025, we entered into a Placement Agency Agreement with Ladenburg Thalmann & Co. Inc. (the "Placement Agent") pursuant to which we agreed to pay the Placement Agent (i) a cash fee equal to 8.0% of the gross proceeds received by us in the 2025 Private Placement; (ii) a management fee equal to 1.0% of the gross proceeds received by us in the 2025 Private Placement; (iii) a cash fee equal to 9.0% of the gross proceeds received by us from the cash exercise of any Series K-1 Warrants and Series K-2 Warrants; and (iv) reimbursement of the Placement Agent's expenses in an amount up to $145,000.

December 2025 Reverse Stock Split

Pursuant to the authority granted by our stockholders at the Company's annual meeting of stockholders held on October 16, 2025, the Company's Board of Directors (the "Board") approved a one-for-ten (1-for-10) reverse stock split (the "2025 Reverse Stock Split") of the Company's common stock and the filing of an amendment to the Company's Amended and Restated Certificate of Incorporation (the "Amendment") to effect the 2025 Reverse Stock Split. The Amendment was filed with the Secretary of State of the State of Delaware on December 12, 2025, and the 2025 Reverse Stock Split became effective in accordance with the terms of the Amendment at 11:59 p.m. Eastern Time on December 15, 2025 (the "Effective Time"). The Amendment provided that, at the Effective Time, every ten (10) shares of the Company's issued and outstanding common stock will automatically be combined into one (1) issued and outstanding share of common stock, without any change in par value per share, which remained $0.01. The 2025 Reverse Stock Split became effective at the Effective Time, and the common stock of the Company began trading on a reverse stock split-adjusted basis on the Nasdaq Capital Market at the open of trading on December 16, 2025.

Compliance with Nasdaq Listing Rule 5550(a)(2)

On December 15, 2025, we received a notice letter (the "Bid Price Notice") from the Listing Qualifications Department of the Nasdaq Stock Market LLC ("Nasdaq") notifying us that because the closing bid price per share for Company common stock was below $1.00 for 30 consecutive business days preceding the date of the Bid Price Notice, we did not meet the $1.00 per share minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) (the "Bid Price Rule").

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we were provided with an initial period of 180 calendar days, or until June 15, 2026 (the "Compliance Period"), to regain compliance with the Bid Price Rule. If, at any time during the Compliance Period, the closing bid price per share of Company common stock is at least $1.00 for a minimum of 10 consecutive business days, Nasdaq will provide us with written notification that we comply with the Bid Price Rule, unless the Staff exercises its discretion to extend this 10 day period pursuant to Nasdaq Listing Rule 5810(c)(3)(H).

We effected the 2025 Reverse Stock Split, described above, in order to regain compliance with the Bid Price Rule. The 2025 Reverse Stock Split became effective at the Effective Time, and the Company's common stock began trading on a reverse stock split-adjusted basis on the Nasdaq Capital Market at the open of trading on December 16, 2025.

On January 7, 2026, we received written notification from Nasdaq notifying us that the Company had regained compliance with the Bid Price Rule as a result of the closing bid price of Company common stock being at $1.00 per share or greater for the prior 14 consecutive business days (from December 16, 2025, to January 6, 2026). Accordingly, the Company is now in compliance with the Bid Price Rule and Nasdaq considers the matter closed.

Corporate Information

Our principal executive offices are located at 135 West 41st Street, 5th Floor, New York, NY 10036. Our telephone number is (646) 790-5756 and our website address is www.ibs.inc. We do not incorporate by reference into this prospectus the information on our website, and you should not consider it as part of this prospectus.

Risks Affecting Our Company

In evaluating an investment in our securities, you should carefully read this prospectus and especially consider the factors incorporated by reference in the sections titled "Risk Factors" commencing on page 6 of this prospectus and our Annual Report on Form 10-K for the year ended June 30, 2025, and in our Quarterly Reports on Form 10-Q, all of which are incorporated by reference herein.

RISK FACTORS

Before making an investment decision, in addition to the risks set forth below, you should consider the "Risk Factors" included under Item 1A. of our most recent Annual Report on Form 10-K and in our updates to those Risk Factors in our Quarterly Reports on Form 10-Q, all of which are incorporated by reference in this prospectus, as updated by our future filings with the SEC. The market or trading price of our common stock could decline due to any of these risks. In addition, please read "Forward-Looking Statements" in this prospectus, where we describe additional uncertainties associated with our business and the forward-looking statements included or incorporated by reference in this prospectus. Please note that additional risks not currently known to us or that we currently deem immaterial may also impair our business and operations.

Risks Related to this Offering

The number of shares being registered for resale is significant in relation to the number of our outstanding shares of common stock.

We have filed a registration statement of which this prospectus is a part to register the shares offered hereunder for sale into the public market by the Selling Stockholders. These shares represent a large number of shares of our common stock, and if sold in the market all at once or at about the same time, could depress the market price of our common stock during the period the registration statement remains effective and could also affect our ability to raise equity capital.

Risks Related to Nasdaq Compliance

We may not be able to satisfy the continued listing requirements of the Nasdaq Capital Market in order to maintain the listing of our common stock.

On December 15, 2025, we received the Bid Price Notice from the Listing Qualifications Department of Nasdaq notifying us that because the closing bid price per share for Company common stock was below $1.00 for 30 consecutive business days preceding the date of the Bid Price Notice, we did not meet the $1.00 per share minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) (the Bid Price Rule).

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we were provided with an initial period of 180 calendar days, or until June 15, 2026, to regain compliance with the Bid Price Rule. If, at any time during the Compliance Period, the closing bid price per share of Company common stock is at least $1.00 for a minimum of 10 consecutive business days, Nasdaq will provide us with written notification that we comply with the Bid Price Rule, unless the Staff exercises its discretion to extend this 10 day period pursuant to Nasdaq Listing Rule 5810(c)(3)(H).

We effected the 2025 Reverse Stock Split, described above, in order to regain compliance with the Bid Price Rule. The 2025 Reverse Stock Split became effective at the Effective Time, and the Company's common stock began trading on a reverse stock split-adjusted basis on the Nasdaq Capital Market at the open of trading on December 16, 2025.

On January 7, 2026, we received written notification from Nasdaq notifying us that the Company had regained compliance with the Bid Price Rule as a result of the closing bid price of Company common stock being at $1.00 per share or greater for the prior 14 consecutive business days (from December 16, 2025, to January 6, 2026). Accordingly, the Company is now in compliance with the Bid Price Rule and Nasdaq considers the matter closed.

Although the 2025 Reverse Stock Split brought the price of our common stock back above $1.00 per share in order to meet the requirements for the continued listing of our common stock on the Nasdaq Capital Market, there can be no assurance that the closing bid price of our common stock will remain at or above $1.00 following the 2025 Reverse Stock Split. If we fail to satisfy any of Nasdaq's continued listing requirements, Nasdaq may take steps to delist our common stock, which could have a materially adverse effect on our ability to raise additional funds as well as the price and liquidity of our common stock.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated herein by reference contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

Given these risks, uncertainties and other factors, many of which are beyond our control, you should not place undue reliance on these forward-looking statements. Except as required by law, we assume no obligation to update these forward-looking statements publicly, or to revise any forward-looking statements to reflect events or developments occurring after the date of this prospectus, even if new information becomes available in the future.

USE OF PROCEEDS

All shares of our common stock offered by this prospectus are being registered for the account of the Selling Stockholders identified herein. We will not receive any of the proceeds from the sale of these shares.

We will receive proceeds from any cash exercise of the Warrants, which, if exercised in cash with respect to all of the 6,791,550 shares of common stock underlying the Warrants, would result in gross proceeds to us of a maximum of approximately $18.87 million.

We intend to use any proceeds received by us from the cash exercise of the Warrants for working capital and general corporate purposes. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to us from the cash exercise of the Warrants. Accordingly, our management will have broad discretion in the timing and application of these proceeds. The holders of the Warrants may exercise the Warrants at their own discretion and at any time until their expiration subject to and in accordance with the terms of the Warrants. As a result, we cannot predict when or if the Warrants will be exercised, and it is possible that the Warrants may expire and never be exercised. In addition, the Warrants are exercisable on a cashless basis if at the time of exercise there is no effective registration statement registering, or the prospectus contained therein is not available for, the issuance of shares of common stock for which the Warrants are exercisable. As a result, we may never receive meaningful, or any, cash proceeds from the exercise of the Warrants.

SELLING STOCKHOLDERS

The shares common stock being offered by the Selling Stockholders are those previously issued to the Selling Stockholders, and those issuable to the Selling Stockholders, upon exercise of the Warrants. For additional information regarding the issuances of those shares of common stock and Warrants, see "Prospectus Summary - Private Placement of Shares of Common Stock and Warrants" above. We are registering the shares of common stock in order to permit the Selling Stockholders to offer the shares for resale from time to time. Except for the ownership of the shares of common stock and the Warrants, the Selling Stockholders have not had any material relationship with us within the past three years.

The table below lists the Selling Stockholders and other information regarding the beneficial ownership of the shares of common stock by each of the Selling Stockholders. The second column lists the number of shares of common stock beneficially owned by each selling shareholder, based on its ownership of the shares of common stock and warrants, as of December 2, 2026, assuming exercise of the warrants held by the Selling Stockholders on that date, without regard to any limitations on exercises.

The third column lists the shares of common stock being offered by this prospectus by the Selling Stockholders.

In accordance with the terms of a registration rights agreement with the Selling Stockholders, this prospectus generally covers the resale of the sum of (i) the number of shares of common stock issued to the Selling Stockholders in the "Prospectus Summary - Private Placement of Shares of Common Stock and Warrants" described above and (ii) the maximum number of shares of common stock issuable upon exercise of the related warrants, determined as if the outstanding warrants were exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, each as of the trading day immediately preceding the applicable date of determination and all subject to adjustment as provided in the registration right agreement, without regard to any limitations on the exercise of the warrants. The fourth column assumes the sale of all of the shares offered by the Selling Stockholders pursuant to this prospectus.

Under the terms of the Warrants and other warrants held by Selling Stockholders, a selling shareholder may not exercise any such warrants to the extent such exercise would cause such selling shareholder, together with its affiliates and attribution parties, to beneficially own a number of shares of common stock which would exceed 4.99% or 9.99%, as applicable, of our then outstanding common stock following such exercise, excluding for purposes of such determination shares of common stock issuable upon exercise of such warrants which have not been exercised. The number of shares in the second and fourth columns do not reflect this limitation. The Selling Stockholders may sell all, some or none of their shares in this offering. See "Plan of Distribution."

	(1)	Shares in Column 2 consist of 1,149,425 shares of common stock underlying Pre-Funded Warrants, 1,149,425 shares of common stock underlying Series K-1 Warrants, and 1,149,425 shares of common stock underlying Series K-2 Warrants. The securities are directly held by Armistice Capital Master Fund Ltd., a Cayman Islands exempted company (the "Master Fund"), and may be deemed to be beneficially owned by: (i) Armistice Capital, LLC ("Armistice Capital"), as the investment manager of the Master Fund; and (ii) Steven Boyd, as the Managing Member of Armistice Capital. The Pre-Funded Warrants are subject to a beneficial ownership limitation of 9.99% and the Series K-1 Warrants and Series K-2 Warrants are subject to a beneficial ownership limitation of 4.99%, which such limitation restricts the Selling Stockholder from exercising that portion of the warrants that would result in the Selling Stockholder and its affiliates owning, after exercise, a number of shares of common stock in excess of the beneficial ownership limitation. The address of Armistice Capital Master Fund Ltd. is c/o Armistice Capital, LLC, 510 Madison Avenue, 7th Floor, New York, NY 10022.
	(2)	Shares in Column 2 consist of 105,000 shares of common stock, 1,044,425 shares of common stock underlying Pre-Funded Warrants, 1,149,425 shares of common stock underlying Series K-1 Warrants, 1,149,425 shares of common stock underlying Series K-2 Warrants, as well as 22,291 shares of common stock underlying Series I Pre-Funded Warrants, 37,956 shares of common stock underlying Series H-1 Warrants, 43,956 shares of common stock underlying Series H-2 Warrants, and 87,912 shares of common stock underlying Series J Warrants. The Pre-Funded Warrants, Series K-1 Warrants, Series K-2 Warrants, Series H-1 Warrants, Series H-2 Warrants, Series I Pre-Funded Warrants, and Series J Warrants are subject to a beneficial ownership limitation of 9.99%, which such limitation restricts Alyeska Master Fund, L.P. (the "Selling Securityholder") from exercising that portion of the warrants that would result in the Selling Stockholder and its affiliates owning, after exercise, a number of shares of common stock in excess of the beneficial ownership limitation. Alyeska Investment Group, L.P., the investment manager of the Selling Securityholder, has voting and investment control of the shares held by the Selling Securityholder. Anand Parekh is the Chief Executive Officer of Alyeska Investment Group, L.P. and may be deemed to be the beneficial owner of such shares. Mr. Parekh, however, disclaims any beneficial ownership of the shares held by the Selling Securityholder. The registered address of Alyeska Master Fund, L.P. is at c/o Maples Corporate Services Limited, P.O. Box 309, Ugland House, South Church Street George Town, Grand Cayman, KY1-1104, Cayman Islands. Alyeska Investment Group, L.P. is located at 77 W. Wacker, Suite 700, Chicago IL 60601.

PLAN OF DISTRIBUTION

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

●

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

●

block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

●

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

●

an exchange distribution in accordance with the rules of the applicable exchange;

●

privately negotiated transactions;

●

settlement of short sales;

●

in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;

●

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

●

a combination of any such methods of sale; or

●

any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

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

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

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

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

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

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