ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus form part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission (the "SEC"), using a "shelf" registration process. This document contains two parts. The first part consists of this prospectus supplement, which provides you with specific information about this offering. The second part, the accompanying prospectus, provides more general information, some of which may not apply to this offering. Generally, when we refer only to the "prospectus," we are referring to both parts combined. This prospectus supplement may add, update or change information contained in the accompanying prospectus. To the extent that any statement we make in this prospectus supplement is inconsistent with statements made in the accompanying prospectus or any documents incorporated by reference herein or therein, the statements made in this prospectus supplement will be deemed to modify or supersede those made in the accompanying prospectus and such documents incorporated by reference herein and therein.

Unless the context otherwise requires, all references to the terms "we," "us," "our," and the "company" throughout this prospectus supplement mean ProPhase Labs, Inc. and its subsidiaries.

All references in this prospectus supplement to our financial statements include, unless the context indicates otherwise, the related notes.

The information contained in this prospectus supplement or the accompanying prospectus is accurate only as of the date of this prospectus supplement or the accompanying prospectus, as applicable, regardless of the time of delivery of this prospectus supplement, the accompanying prospectus or of any sale of the securities. We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference in this prospectus supplement or the accompanying prospectus were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

RISK FACTORS

An investment in our shares of common stock involves a high degree of risk. Before deciding whether to invest in our securities, you should carefully consider the risks discussed under the sections captioned "Risk Factors" contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as amended (the "Form 10-K"), any subsequently filed Quarterly Report on Form 10-Q and in other documents that we subsequently file with the SEC, all of which are incorporated by reference in this prospectus supplement and the accompanying prospectus in their entirety, together with other information in this prospectus supplement, the accompanying prospectus, the information and documents incorporated by reference herein and therein, and in any free writing prospectus that we have authorized for use in connection with this offering. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment.

Risks Relating to this Offering and Ownership of Our Common Stock

As an investor, you may lose all of your investment.

Investing in our securities involves a high degree of risk. As an investor, you may never recoup all, or even part, of your investment and you may never realize any return on your investment. You must be prepared to lose all of your investment.

Management will have broad discretion as to the use of proceeds from this offering and may not use them effectively.

Our management will have broad discretion as to the application of the net proceeds from this offering and our stockholders will not have the opportunity as part of their investment decisions to assess whether the net proceeds are being used appropriately. You may not agree with our decisions, and our use of the proceeds may not yield any return on your investment. Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. Our failure to apply the net proceeds of this offering effectively could compromise our ability to pursue our growth strategy and we might not be able to yield a significant return, if any, in our investment of these net proceeds. You will not have the opportunity to influence our decisions on how to use our net proceeds from this offering.

You will suffer immediate and substantial dilution in the net tangible book value per share of the common stock that you purchase in this offering.

Because the offering price per share of our common stock being offered in this offering may be higher than the book value per share of our common stock, you may suffer substantial dilution in the net tangible book value of the common stock you purchase in this offering. For a further description of the dilution that investors in this offering will experience, see "Dilution."

Investors in this offering will also be subject to increased dilution upon the exercise of outstanding stock options and warrants.

Future sales of common stock by stockholders may have an adverse effect on the then prevailing market price of our common stock.

Based on the sale of 4,170,000 shares of our common stock, we will be selling a number of shares of common stock which represents approximately 21.86% of the number of shares of common stock that we currently have outstanding. Sales of a substantial number of shares of our common stock issued in this offering in the public market following this offering, together with shares of our common stock issuable upon conversion or exercise of currently outstanding derivative securities, could cause the market price of our common stock to decline and could impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our common stock or other equity-related securities would have on the market price of our common stock.

You may experience dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the price per share in this offering. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions may be lower than the price per share paid by investors in this offering.

Risks Related to Our Business Generally

FDA's finalized regulations on laboratory-developed tests may impact our operations adversely, and we may not be able to comply with the requirements.

We market our genetic tests as laboratory-developed tests ("LDT"), and plan to also initially market our BE-Smart Esophageal Pre-Cancer as an LDT. Until recently, the FDA has exercised enforcement discretion on LDTs that are marketed in the United States, provided that the LDTs can meet certain conditions that the FDA has outlined. However, on May 6, 2024, the FDA issued a final rule aimed at helping to ensure the safety and effectiveness of laboratory developed tests (LDTs). The rule amends the FDA's regulations to make explicit that in vitro diagnostic products ("IVD") are medical devices under the Federal Food, Drug, and Cosmetic Act (FD&C Act) including when the manufacturer of the IVD is a laboratory. Along with this amendment, the FDA is finalizing a policy under which the FDA will provide greater oversight of IVDs offered as LDTs through a phaseout of its general enforcement discretion approach for LDTs over the course of four years, as well as targeted enforcement discretion policies for certain categories of IVDs manufactured by laboratories. As a result of the final regulations, premarket review, clearance, or approvals may be required by FDA for the products that we are currently marketing or plan to market as LDTs. Our business and operations may be adversely affected because we may be required to cease sales of such products and be required to expend significant resources into collecting data from clinical trials, ensuring compliance with the applicable requirements for medical devices, and preparing and submitting premarket applications for the FDA's review. We may not be able to complete the required clinical trials to enable marketing of our tests due to resource constraints, or we may not be able to complete them in a timely manner. We also may not be able to comply with the associated regulatory requirements including those of premarket authorization, medical device reporting, quality system regulations, and others. In addition, even if we are able to comply with such requirements or complete the clinical trials in a timely manner, there is no guarantee that FDA will clear or approve our products. FDA may also determine that our tests are not safe or effective, and that they must be removed from the market. The FDA may bring enforcement actions against LDTs that are on the market by sending warning letters, untitled letters, it-has-come-to-our-attention letters, or through other actions such as seizure, recalls, civil monetary penalties, injunction, and import refusals and import alerts, among others. If we cannot obtain the required premarket review, clearance, or approval, we may be forced to stop the marketing of our products, which will impact our operations and financial conditions adversely.

Servicing our debt will require a significant amount of cash, and we may not have sufficient cash flow from our business to pay our debt.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. We had, as of June 30, 2024, approximately (i) $16.1 million in working capital, (ii) $2.4 million in cash and cash equivalents, and (iii) $13.6 million of outstanding indebtedness, net of discounts. In addition, on August 15, 2024, we amended and restated the unsecured promissory note and guaranty previously issued to JXVII Trust that increased the principal amount from $7.6 million to $10.0 million. Our business may not generate cash flow from operations in the future sufficient to service our debt obligations and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

Our projections of future performance may not be indicative of actual results

From time to time, we may provide statements to the marketplace in the form of press releases that contain projections related to our future performance. These include statements relating to our projected revenues, our projected collection of receivables, our estimates of future operating and financial results and our planned strategic initiatives including our potential discussions regarding strategic partnerships and M&A activity. Although this information reflects the good faith expectations and estimates of our management based on the information available at the time that such statements were made, there can be no assurance that our actual performance and results will not differ materially from those contained in these projections. Investors are cautioned not to place undue reliance on any projections that may be provided by us.

Cautionary Note Regarding Forward-Looking Statements

This prospectus supplement (including any documents incorporated by reference herein) contains statements with respect to us which constitute ''forward-looking statements'' within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and are intended to be covered by the ''safe harbor'' created by those sections. Forward-looking statements, which are based on certain assumptions and reflect our plans, estimates and beliefs, can generally be identified by the use of forward-looking terms such as "believes," "expects," "may," "will," "should," "could," "seek," "intends," "plans," "estimates," "anticipates" or other comparable terms. These forward-looking statements include, but are not limited to, statements concerning future events, our future financial performance, business strategy, product development strategy, and plans and objectives of management for future operations. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed in "Risk Factors" in this prospectus supplement and the documents incorporated by reference herein.

We caution readers not to place undue reliance upon any such forward-looking statements, which speak only as of the date they are made. We disclaim any obligation, except as specifically required by law and the rules of the SEC, to publicly update or revise any such statements to reflect any change in company expectations or in events, conditions or circumstances on which any such statements may be based, or that may affect the likelihood that actual results will differ from those set forth in the forward-looking statements.

You should read this prospectus supplement, the accompanying prospectus, and the documents that we incorporate by reference herein and therein and have filed as exhibits to the registration statement of which this prospectus supplement is part, completely and with the understanding that our actual future results may be materially different from what we expect. You should assume that the information appearing in this prospectus supplement is accurate as of the date on the cover of this prospectus supplement only. Our business, financial condition, results of operations and prospects may change. We may not update these forward-looking statements, even though our situation may change in the future, unless we have obligations under the federal securities laws to update and disclose material developments related to previously disclosed information. We qualify all of the information presented in this prospectus supplement, and particularly our forward-looking statements, by these cautionary statements.

USE OF PROCEEDS

We estimate that we will receive net proceeds of approximately $2.40 million from this offering, or approximately $2.81 million if the underwriters exercise their over-allotment option in full, in each case after deducting the underwriting discount and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering for working capital and general corporate purposes, which may include capital expenditures, product development and commercialization expenditures, and acquisitions of companies, businesses, technologies and products within and outside the diagnostic services, genomics and consumer products industry.

Pending our use of the net proceeds from this offering, we intend to maintain the net proceeds as cash deposits or cash management instruments, such as U.S. government securities or money market mutual funds.

CAPITALIZATION

The following table sets forth our cash and cash equivalents and capitalization as of June 30, 2024:

●	on an actual basis; and

●	on an as adjusted basis to reflect the sale and issuance of 4,170,000 shares of common stock in this offering at the public offering price of $0.72 per share, after deducting the underwriting discount and estimated offering expenses payable by us.

		As of June 30, 2024
(amounts in dollars and in thousands, except share and per share amounts)		Actual			As Adjusted
Cash and cash equivalents		$	1,780			$	4,397
Stockholders' equity (deficit):

Common stock, $0.0005 par value, 50,000,000 shares authorized; 19,078,529 shares outstanding, actual and 23,248,529 shares outstanding, as adjusted			18				22
Additional paid-in capital			125,703				128,316

Accumulated deficit			(17,447	)			(17,447	)
Accumulated other comprehensive loss			(198	)			(198	)
Total stockholders' equity			44,076				46,693
Total capitalization		$	93,678			$	96,295

The above discussion and table are based on 19,078,529 shares of common stock outstanding as of June 30, 2024 and excludes the following:

●	4,253,750 shares of common stock issuable upon the exercise of stock options outstanding under our equity compensation plans and inducement stock option awards, with a weighted-average exercise price of $6.65 per share;

●	376,000 shares of common stock issuable upon the exercise of warrants with a weighted average exercise price of $9.13 per share; and

●	367,035 shares of common stock reserved for future issuance under the 2022 Plan.

Except as otherwise indicated herein, all information in this prospectus supplement assumes:

●	no exercise of the underwriter's over-allotment option;

●	no exercise of the Representative's Warrants to be issued to the Representative of the underwriters in this offering; and
	●	no issuance of shares of common stock valued at $2.0 million which are issuable to the Stella Sellers upon the Commercialization Event.

DILUTION

If you purchase shares of common stock in this offering, you will experience dilution to the extent of the difference between the public offering price per share in this offering and our as adjusted net tangible book value per share immediately after this offering.

Our net tangible book value as of June 30, 2024 was approximately $27.8 million, or $1.46 per share. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the aggregate number of shares of our common stock outstanding as of June 30, 2024. Dilution in net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the net tangible book value per share of our common stock immediately after this offering.

After giving effect to the sale of 4,170,000 shares of our common stock at a public offering price of $0.72 per share in this offering, and after deducting the underwriting discount and estimated offering expenses payable by us, our net tangible book value as of June 30, 2024 would have been approximately $30.4 million, or $1.31 per share of common stock. This represents an immediate decrease in as adjusted net tangible book value of approximately $0.15 per share to existing stockholders and an immediate dilution in net tangible book value of approximately $0.59 per share to new investors in this offering. The following table illustrates this dilution on a per share basis:

Public offering price per share of common stock					$	0.72
Net tangible book value per share as of June 30, 2024		$	1.46
Decrease in net tangible book value per share attributable to this offering		$	(0.15	)
As adjusted net tangible book value per share as of June 30, 2024, after giving effect to this offering			1.31
Dilution per share to new investors in this offering					$	(0.59	)

If the underwriters exercise in full its option to purchase additional shares of common stock, the as adjusted net tangible book value per share would be approximately $1.29 per share, which amount represents an immediate decrease in net tangible book value of approximately $0.17 per share of our common stock to existing stockholders and an immediate dilution in net tangible book value of approximately $0.57 per share of our common stock to new investors purchasing shares of common stock in this offering.

The above discussion and table are based on 19,078,529 shares of common stock outstanding as of June 30, 2024 and excludes the following:

●	4,253,750 shares of common stock issuable upon the exercise of stock options outstanding under our equity compensation plans and inducement stock option awards, with a weighted-average exercise price of $6.65 per share;

●	376,000 shares of common stock issuable upon the exercise of warrants with a weighted average exercise price of $9.13 per share; and

●	367,035 shares of common stock reserved for future issuance under the 2022 Plan.

Except as otherwise indicated herein, all information in this prospectus supplement assumes:

●	no exercise of the underwriter's over-allotment option;

●	no exercise of the Representative's Warrants to be issued to the Representative of the underwriters in this offering; and
	●	no issuance of shares of common stock valued at $2.0 million which are issuable to the Stella Sellers upon the Commercialization Event.

If the holders of outstanding options or warrants or other outstanding convertible securities exercise or convert those options or warrants or other outstanding convertible securities at prices below the public offering price, you will incur further dilution. In addition, 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. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

DESCRIPTION OF SECURITIES WE ARE OFFERING

Common Stock

The description of our Common Stock is incorporated by reference to Exhibit 4.3 to our annual report on Form 10-K for the fiscal year ended December 31, 2019, filed with the SEC on March 26, 2020.

UNDERWRITING

ThinkEquity LLC is acting as the Representative of the underwriters of the offering. We have entered into an underwriting agreement dated November 7, 2024 with the Representative. Subject to the terms and conditions of the underwriting agreement, we have agreed to sell to each underwriter named below, and each underwriter named below has severally agreed to purchase, at the public offering price less the underwriting discounts set forth on the cover page of this prospectus supplement, the number of shares of common stock at the public offering price, less the underwriting discount, as set forth on the cover page of this prospectus supplement, the number of shares of common stock listed next to its name in the following table:

Underwriter		Number of Shares of Common Stock
ThinkEquity LLC			4,170,000
Total			4,170,000

The underwriters are committed to purchase all the shares of common stock offered by us. The obligations of the underwriters may be terminated upon the occurrence of certain events specified in the underwriting agreement. Furthermore, the underwriting agreement provides that the obligations of the underwriters to pay for and accept delivery of the shares offered by us in this prospectus supplement are subject to various representations and warranties and other customary conditions specified in the underwriting agreement, such as receipt by the underwriters of officers' certificates and legal opinions.

We have agreed to indemnify the underwriters against specified liabilities, including liabilities under the Securities Act, and to contribute to payments the underwriters may be required to make in respect thereof.

The underwriters are offering the shares of common stock subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel and other conditions specified in the underwriting agreement. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

We have granted the Representative an over-allotment option. This option, which is exercisable for up to 45 days after the date of this prospectus supplement, permits the underwriters to purchase up to an aggregate of additional shares of common stock (equal to 15% of the total number of shares of common stock sold in this offering) at the public offering price per share, less underwriting discount, solely to cover over-allotments, if any. If the underwriters exercise this option in whole or in part, then the underwriters will be severally committed, subject to the conditions described in the underwriting agreement, to purchase the additional shares of common stock in proportion to their respective commitments set forth in the prior table.

Discounts, Commissions and Reimbursement

The Representative has advised us that the underwriters propose to offer the shares of common stock to the public at the public offering price per share set forth on the cover page of this prospectus supplement. The underwriters may offer securities to securities dealers at that price less a concession of not more than $0.0288 per share. After the offering to the public, the public offering price and other selling terms may be changed by the Representative.

The following table summarizes the underwriting discount and proceeds, before expenses, to us:

					Total
		Per Share			Without Over-Allotment Option			With Over- Allotment Option
Public offering price		$	0.72			$	3,002,400			$	3,452,760
Underwriting discount (7%)		$	0.0504			$	210,168			$	241,693
Proceeds, before expenses, to us		$	0.6696			$	2,792,232			$	3,211,067
Non-accountable expense allowance (1%)		$	0.0072			$	30,024			$	34,528

In addition, we have also agreed to pay the Representative (i) a non-accountable expense allowance equal to 1% of the public offering price; (ii) the fees and expenses of the underwriter's legal counsel not to exceed $125,000; (iii) the $12,000 cost associated with the use of Ipreo's book building, prospectus tracking and compliance software for the offering; (iv) $10,000 for data services and communications expenses; and (v) up to $25,000 of Representative's actual accountable "road show", market making and trading, and clearing firm settlement expenses for this offering.

We estimate the expenses of this offering payable by us, not including underwriting discount, will be approximately $395,000, or approximately $399,000 if the underwriters exercise their over-allotment option in full.

Representative's Warrants

Upon closing of this offering, we have agreed to issue to the Representative, or its designees, as partial compensation warrants to purchase up to 208,500 shares of common stock (or 239,775 shares of common stock if the underwriter's over-allotment option is exercised in full), which is equal to 5% of the aggregate number of shares of common stock sold in this offering (the "Representative's Warrants"). The Representative's Warrants will be exercisable at a per share exercise price of $0.90, which is equal to 125% of the public offering price per share of common stock in this offering. The Representative's Warrants are exercisable at any time and from time to time, in whole or in part, during the five year period commencing on the closing date of this offering.

The Representative's Warrants provide for registration rights upon request, in certain cases. The one-time demand registration right provided will not be greater than five years from the effective date of the registration statement in compliance with FINRA Rule 5110(g)(8)(C). The unlimited piggyback registration rights provided will not be greater than seven years from the effective date of the registration statement in compliance with FINRA Rule 5110(g)(8)(D). We will bear all fees and expenses attendant to registering the securities issuable on exercise of the warrants other than underwriting commissions incurred and payable by the holders. The exercise price and number of shares issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend or our recapitalization, reorganization, merger or consolidation. However, the warrant exercise price or underlying shares will not be adjusted for issuances of shares of common stock at a price below the warrant exercise price.

Lock-Up Agreements

The Company has agreed for a period of three months after the date of the underwriting agreement, and each of its directors and officers has agreed for a period of 120 days after the date of the underwriting agreement, not to do any of the following without the express written consent of the Representative:

●

issue (in the case of us), offer, pledge, sell, transfer, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of any shares of common stock or other capital stock or any securities convertible into or exercisable or exchangeable for our common stock or other capital stock; or

Additionally, we have agreed for a period of twelve (12) months after the closing of this offering that we will not directly or indirectly, in any "at the market", continuous equity or variable rate transaction, other than pursuant to our Sales Agreement with the Representative dated December 28, 2021, offer to sell, sell, contract to sell, grant any option to sell or otherwise dispose of shares of our capital stock or any securities convertible into, exercisable or exchangeable for shares of our capital stock without the express written consent of the Representative.

Right of First Refusal

We have granted the Representative an irrevocable right of first refusal, for a period of twelve (12) months from the closing of the offering, to act as sole investment banker, sole book-runner and/or sole placement agent and/or merger and acquisition advisor, at the Representative's sole discretion, for each and every future public and private equity offering, including all equity linked financings (subject to certain exceptions), as well as acquisition or disposition of business units, entering into a merger, consolidation or other business combination, share purchase or capital exchange, asset sale or acquisition, tender offer, recapitalization, reorganization, consolidation, amalgamation, or similar business combination (subject to certain exceptions), during such twelve (12) month period for the Company or any successor to or any subsidiary of the Company on terms customary to the Representative. The Representative shall have the sole right to determine whether or not any other broker dealer shall have the right to participate in any such transaction and the economic terms of such participation.

Nasdaq Capital Market

Our shares of common stock are listed on the Nasdaq Capital Market under the symbol "PRPH."

Electronic Offer, Sale and Distribution of Securities

A prospectus in electronic format may be made available on the websites maintained by one or more of the underwriters or selling group members. The Representative may agree to allocate a number of securities to underwriters and selling group members for sale to its online brokerage account holders. Internet distributions will be allocated by the underwriters and selling group members that will make internet distributions on the same basis as other allocations. Other than the prospectus in electronic format, the information on these websites is not part of, nor incorporated by reference into, this prospectus supplement or the registration statement of which this prospectus supplement forms a part, has not been approved or endorsed by us, and should not be relied upon by investors.

Stabilization

In connection with this offering, the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate-covering transactions, penalty bids and purchases to cover positions created by short sales.

Stabilizing transactions permit bids to purchase shares so long as the stabilizing bids do not exceed a specified maximum, and are engaged in for the purpose of preventing or retarding a decline in the market price of the shares while the offering is in progress.

Syndicate covering transactions involve purchases of shares in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the Representative to reclaim a selling concession from a syndicate member when the shares originally sold by that syndicate member are purchased in stabilizing or syndicate covering transactions to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our shares of common stock or preventing or retarding a decline in the market price of our shares of common stock. As a result, the price of our common stock in the open market may be higher than it would otherwise be in the absence of these transactions. Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of our common stock. These transactions may be effected in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time.

Passive Market Making

In connection with this offering, the underwriters and any selling group members may engage in passive market making transactions in our common stocks on Nasdaq in accordance with Rule 103 of Regulation M under the Exchange Act during a period before the commencement of offers or sales of shares of our common stock and extending through the completion of the distribution. A passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker's bid, that bid must then be lowered when specified purchase limits are exceeded.

Other Relationships

Certain of the underwriters and their affiliates may in the future provide various investment banking, commercial banking and other financial services for us and our affiliates for which they may in the future receive customary fees.

Offer restrictions outside the United States

Other than in the United States, no action has been taken by us or the underwriters that would permit a public offering of the securities offered by this prospectus supplement in any jurisdiction where action for that purpose is required.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission, or SEC, utilizing a "shelf" registration process. Under this shelf registration process, we may offer shares of our common stock, preferred stock and/or warrants, either individually or in units, in one or more offerings, with a total value of up to $300,000,000. This prospectus provides you with a general description of the securities we may offer. Each time we offer a type or series of securities under this prospectus, we will provide a prospectus supplement that will contain specific information about the terms of that offering.

This prospectus does not contain all of the information included in the registration statement. For a more complete understanding of the offering of the securities, you should refer to the registration statement, including its exhibits. The prospectus supplement may also add, update or change information contained or incorporated by reference in this prospectus.

USE OF PROCEEDS

We cannot assure you that we will receive any proceeds in connection with securities that may be offered pursuant to this prospectus. Unless otherwise indicated in the applicable prospectus supplement, we intend to use any net proceeds from the sale of securities under this prospectus for our operations and for other general corporate purposes, including, but not limited to, our internal research and development programs, general working capital and possible future acquisitions.

DESCRIPTION OF CAPITAL STOCK

General

Our authorized capital stock consists of 51,000,000 shares, all with a par value of $0.0005 per share, 50,000,000 of which are designated as common stock and 1,000,000 of which are designated as preferred stock.

The following description of our capital stock and certain provisions of our Certificate of Incorporation and our Amended and Restated Bylaws, or Bylaws, are summaries and are qualified by reference to our Certificate of Incorporation and our Bylaws.

As of November 4, 2021, we had 15,515,055 shares of our common stock outstanding and zero shares of preferred stock outstanding. As of November 4, 2021, we also had outstanding options to acquire 4,896,874 shares of our common stock, having a weighted-average exercise price of $3.17 per share, and warrants to purchase 855,000 shares of our common stock, having a weighted-average exercise price of $8.23 per share.

Common Stock

The holders of our common stock are entitled to one vote per share on all matters to be voted upon by the stockholders, except on matters relating solely to terms of preferred stock. Subject to preferences that may be applicable to any outstanding preferred stock, the holders of common stock will be entitled to receive ratably such dividends, if any, as may be declared from time to time by the board of directors out of funds legally available therefor. In the event of our liquidation, dissolution or winding up, the holders of our common stock will be entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The holders of our common stock will have no preemptive or conversion rights or other subscription rights. There will be no redemption or sinking fund provisions applicable to our common stock.

Preferred Stock

Pursuant to the terms of our Certificate of Incorporation, our board of directors has the authority to issue preferred stock in one or more series and to fix the number of shares constituting such series and the designation of such series, the voting powers, if any, of the shares of such series, and the preferences and relative participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of such series, without further vote or action by the stockholders. Although we have no present plans to issue any shares of preferred stock, the issuance of shares of preferred stock, could decrease the amount of earnings and assets available for distribution to the holders of common stock, could adversely affect the rights and powers, including voting rights, of the common stock, and could have the effect of delaying, deterring or preventing a change of control of us or an unsolicited acquisition proposal.

Anti-Takeover Effects of Delaware Law and Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

The provisions of Delaware law and our Certificate of Incorporation and Bylaws, could discourage or make it more difficult to accomplish a proxy contest or other change in our management or the acquisition of control by a holder of a substantial amount of our voting stock. It is possible that these provisions could make it more difficult to accomplish, or could deter, transactions that stockholders may otherwise consider to be in their best interests or in our best interests. These provisions are intended to enhance the likelihood of continuity and stability in the composition of our board of directors and in the policies formulated by the board of directors and to discourage certain types of transactions that may involve an actual or threatened change of our control. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal and to discourage certain tactics that may be used in proxy fights. Such provisions also may have the effect of preventing changes in our management.

Delaware Statutory Business Combinations Provision. We are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, or the DGCL. Section 203 prohibits a publicly-held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. For purposes of Section 203, a "business combination" is defined broadly to include a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder, and, subject to certain exceptions, an "interested stockholder" is a person who, together with his or her affiliates and associates, owns, or within three years prior, did own, 15% or more of the corporation's voting stock.

Blank-Check Preferred Stock. Our board of directors is authorized to issue, without stockholder approval, preferred stock, the rights of which will be determined at the discretion of the board of directors and that, if issued, could operate as a "poison pill" to dilute the stock ownership of a potential hostile acquirer to prevent an acquisition that our board of directors does not approve.

Special Meetings of Stockholders. Special meetings of the stockholders may be called at any time only by the Chairman of the board of directors or the board of directors, subject to the rights of the holders of any series of preferred stock then outstanding.

No Written Consent of Stockholders. Our Bylaws provide that all stockholder actions are required to be taken by a vote of the stockholders at an annual or special meeting, and that stockholders may not take any action by written consent in lieu of a meeting.

Advance Notice Provisions for Stockholder Proposals and Stockholder Nominations of Directors. Our Bylaws provide that, for nominations to the board of directors or for other business to be properly brought by a stockholder before a meeting of stockholders, the stockholder must first have given timely notice of the proposal in writing to our Secretary. For an annual meeting, a stockholder's notice generally must be delivered not less than 90 days or more than 120 days prior to the anniversary of the previous year's annual meeting.

Election and Removal of Directors. Except as may otherwise be provided by the DGCL, any director or the entire board of directors may be removed, with or without cause, at an annual meeting or a special meeting called for that purpose, by the affirmative vote of the holders of a majority of the shares then entitled to vote at an election of directors. Vacancies on our board of directors resulting from the removal of directors and newly created directorships resulting from any increase in the number of directors may be filled solely by the affirmative vote of a majority of the remaining directors then in office. This system of electing and removing directors may discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of our directors. Our Certificate of Incorporation and Bylaws do not provide for cumulative voting in the election of directors.

Exclusive Jurisdiction. Our Bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to the Company or the Company's stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, the Certificate of Incorporation or the Bylaws, or (iv) any action asserting a claim against the Company governed by the internal affairs doctrine."

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC.

Stock Market Listing

DESCRIPTION OF WARRANTS

General

We may issue warrants to purchase shares of our common stock and/or preferred stock. We may offer warrants separately or together with one or more additional warrants, common stock, or preferred stock, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with the certificates relating to the rights of the series of certificates and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights. The following description sets forth certain general terms and provisions of the rights to which any prospectus supplement may relate. The particular terms of the warrant to which any prospectus supplement may relate and the extent, if any, to which the general provisions may apply to the rights so offered will be described in the applicable prospectus supplement. To the extent that any particular terms of the warrant, warrant agreement or warrant certificates described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by that prospectus supplement. We encourage you to read the applicable warrant agreement and warrant certificate for additional information before you decide whether to purchase any of our rights.

We will provide in a prospectus supplement the following terms of the warrants being issued:

	●	the specific designation and aggregate number of, and the price at which we will issue, the warrants;

	●	the date on which the right to exercise the warrants will begin and the date on which that right will expire or, if you may not continuously exercise the warrants throughout that period, the specific date or dates on which you may exercise the warrants;
	●	whether the warrants will be issued in fully registered form or bearer form, in definitive or global form or in any combination of these forms, although, in any case, the form of a warrant included in a unit will correspond to the form of the unit and of any security included in that unit;
	●	any applicable material U.S. federal income tax consequences;
	●	the identity of the warrant agent for the warrants and of any other depositaries, execution or paying agents, transfer agents, registrars or other agents;
	●	the proposed listing, if any, of the warrants or any securities purchasable upon exercise of the warrants on any securities exchange;
	●	if applicable, the date from and after which the warrants and the common stock and/or preferred stock will be separately transferable;
	●	if applicable, the minimum or maximum amount of the warrants that may be exercised at any one time;
	●	information with respect to book-entry procedures, if any;
	●	the anti-dilution provisions of the warrants, if any;
	●	any redemption or call provisions;
	●	whether the warrants may be sold separately or with other securities as parts of units; and
	●	any additional terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

Warrant Agent

The warrant agent for any warrants we offer will be set forth in the applicable prospectus supplement.

DESCRIPTION OF UNITS

The following description, together with the additional information that we include in any applicable prospectus supplements summarizes the material terms and provisions of the units that we may offer under this prospectus. While the terms we have summarized below will apply generally to any units that we may offer under this prospectus, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement. The terms of any units offered under a prospectus supplement may differ from the terms described below.

We will incorporate by reference from reports that we file with the SEC, the form of unit agreement that describes the terms of the series of units we are offering, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the particular series of units that we may offer under this prospectus, and the complete unit agreement and any supplemental agreements that contain the terms of the units.

General

We may issue units consisting of common stock, preferred stock and/or warrants for the purchase of common stock or preferred stock in one or more series, in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each security included in the unit. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

We will describe in the applicable prospectus supplement the terms of the series of units being offered, including:

	●	the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;
	●	any provisions of the governing unit agreement;
	●	the price or prices at which such units will be issued;
	●	the applicable United States federal income tax considerations relating to the units; and
	●	any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units.

The provisions described in this section, as well as those set forth in any prospectus supplement or as described under "Description of Capital Stock" and "Description of Warrants" will apply to each unit, as applicable, and to any common stock, preferred stock or warrant included in each unit, as applicable.

Unit Agent

The name and address of the unit agent for any units we offer will be set forth in the applicable prospectus supplement.

Issuance in Series

We may issue units in such amounts and in such numerous distinct series as we determine.

Enforceability of Rights by Holders of Units

Each unit agent will act solely as our agent under the applicable unit agreement and will not assume any obligation or relationship of agency or trust with any holder of any unit. A single bank or trust company may act as unit agent for more than one series of units. A unit agent will have no duty or responsibility in case of any default by us under the applicable unit agreement or unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a unit may, without the consent of the related unit agent or the holder of any other unit, enforce by appropriate legal action its rights as holder under any security included in the unit.

PLAN OF DISTRIBUTION

General Plan of Distribution

We may offer securities under this prospectus from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods. We may sell the securities (1) through underwriters or dealers, (2) through agents, (3) in "at the market offerings" within the meaning of Rule 415(a)(4) of the Securities Act, (4) directly to one or more purchasers, or (5) through a combination of such methods. We may distribute the securities from time to time in one or more transactions at:

	●	a fixed price or prices, which may be changed from time to time;
	●	market prices prevailing at the time of sale;
	●	prices related to the prevailing market prices; or
	●	negotiated prices.

We may directly solicit offers to purchase the securities being offered by this prospectus. We may also designate agents to solicit offers to purchase the securities from time to time. We will name in a prospectus supplement any underwriter or agent involved in the offer or sale of the securities.

If we utilize a dealer in the sale of the securities being offered by this prospectus, we will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

If we utilize an underwriter in the sale of the securities being offered by this prospectus, we will execute an underwriting agreement with the underwriter at the time of sale, and we will provide the name of any underwriter in the prospectus supplement which the underwriter will use to make re-sales of the securities to the public. In connection with the sale of the securities, we, or the purchasers of the securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and the underwriter may compensate those dealers in the form of discounts, concessions or commissions. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis and a dealer will purchase securities as a principal, and may then resell the securities at varying prices to be determined by the dealer.

With respect to underwritten public offerings, negotiated transactions and block trades, we will provide in the applicable prospectus supplement information regarding any compensation we pay to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof.

If so indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in the prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

	●	the purchase by an institution of the securities covered under that contract shall not at the time of delivery be prohibited under the laws of the jurisdiction to which that institution is subject; and
	●	if the securities are also being sold to underwriters acting as principals for their own account, the underwriters shall have purchased such securities not sold for delayed delivery. The underwriters and other persons acting as our agents will not have any responsibility in respect of the validity or performance of delayed delivery contracts.

Shares of our common stock sold pursuant to the registration statement of which this prospectus is a part will be authorized for listing and trading on the Nasdaq Capital Market. The applicable prospectus supplement will contain information, where applicable, as to any other listing, if any, on the Nasdaq Capital Market or any securities market or other securities exchange of the securities covered by the prospectus supplement. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.

In order to facilitate the offering of the securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing the applicable security in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if the securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

We may engage in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. In addition, we may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be named in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

In compliance with the guidelines of the Financial Industry Regulatory Authority, Inc., or FINRA, the maximum consideration or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement.

The underwriters, dealers and agents may engage in other transactions with us, or perform other services for us, in the ordinary course of their business.
