34,684,859 Shares of Common Stock

________________

This prospectus relates to the resale of up to 34,684,859 shares (the “Shares”) of Heart Test Laboratories, Inc.’s (“we,” “us,” “our,” “HeartSciences” or the “Company”) common stock, $0.001 par value per share (the “Common Stock”), by the selling stockholders (the “Selling Stockholders”) named in this prospectus, consisting of: (i) 4,854,853 shares of Common Stock (the “Mount Sinai Shares”) issued on November 16, 2023 to Icahn School of Medicine at Mount Sinai (“Mount Sinai”) pursuant to the Securities Purchase Agreement, dated September 20, 2023, between us and Mount Sinai (the “Mount Sinai Securities Purchase Agreement”), (ii) 710,605 shares of Common Stock issuable upon the exercise of pre-funded warrants to purchase Common Stock issued on November 16, 2023 to Mount Sinai pursuant to the Mount Sinai Securities Purchase Agreement (the “MTS Pre-Funded Warrants”), (iii) 914,148 shares of Common Stock issuable upon the exercise of our warrants to purchase Common Stock issued on November 16, 2023 to Mount Sinai pursuant to the Mount Sinai Securities Purchase Agreement (the “MTS Warrants” and together with the MTS Pre-Funded Warrants, the “Warrants” and the shares of Common Stock issuable in connection with the exercise of Warrants, the “Warrant Shares”), (iv) up to 21,423,965 shares of Common Stock (the “Lincoln Park Shares”) issuable to Lincoln Park Capital Fund, LLC (“Lincoln Park”) pursuant to the Purchase Agreement, dated March 10, 2023, between us and Lincoln Park (the “Lincoln Park Purchase Agreement”), (v) 3,656,288 shares of Common Stock (the “Adams Shares”) issued on November 16, 2023 to John Q. Adams (“Adams”) pursuant to the note conversion letter agreement, dated November 16, 2023, between us and Adams, and (vi) 3,125,000 shares of Common Stock (the “Matthews Shares”) issued on November 16, 2023 to Matthews Southwest Holdings, Inc. (“Matthews”) pursuant to the note conversion letter agreement, dated November 16, 2023, between us and Matthews (the “Matthews Note Conversion Letter Agreement”). For more information about the Selling Stockholders, please see the section of this prospectus entitled “Selling Stockholders” beginning on page 31.

We are registering the resale of the Mount Sinai Shares and the Warrant Shares as required by the Mount Sinai Securities Purchase Agreement. We are registering the resale of the Lincoln Park Shares pursuant to the terms of the Registration Rights Agreement, dated March 10, 2023, between us and Lincoln Park.

Our registration of the Shares covered by this prospectus does not mean that the Selling Stockholders will offer or sell any of their respective Shares. The Selling Stockholders may sell or otherwise dispose of the shares of Common Stock described in this prospectus in a number of different ways and at varying prices. See “Plan of Distribution” beginning on page 34 of this prospectus for more information about how the Selling Stockholders may sell or otherwise dispose of the shares of Common Stock being registered pursuant to this prospectus.

We will not receive any of the proceeds from the Shares sold by the Selling Stockholders, other than any proceeds from any cash exercise of the Warrants. We will, however, receive proceeds from the sale of the Lincoln Park Shares directly to Lincoln Park pursuant to the Lincoln Park Purchase Agreement.

Lincoln Park is an “underwriter” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). For more information, please see the section of this prospectus titled “Plan of Distribution” beginning on page 34.

No other underwriter or other person has been engaged to facilitate the sale of the Shares in this offering. The other Selling Stockholders may, individually but not severally, be deemed to be an “underwriter” within the meaning of the Securities Act of their respective Shares that they are offering pursuant to this prospectus. The Selling Stockholders will bear all commissions and discounts, if any, and similar expenses attributable to their respective sales of the Shares. We will pay the expenses (except brokerage fees and commissions and similar expenses) incurred in registering the Shares, including legal and accounting fees. See “Plan of Distribution” beginning on page 34.

We previously completed our initial public offering (“IPO”) of units consisting of shares of Common Stock and warrants to purchase shares of Common Stock (the “IPO Warrants”), on June 17, 2022. Our Common Stock and our IPO Warrants are listed on the Nasdaq Capital Market under the symbols “HSCS” and “HSCSW,” respectively. On February 28, 2024, the last reported sale price of our Common Stock on the Nasdaq Capital Market was $0.1164 per share and the closing price of our IPO Warrants was $0.085 per warrant.

We are an “emerging growth company” as that term is used in the Jumpstart Our Business Startups Act of 2012 and, as such, have elected to comply with certain reduced public company reporting requirements for this prospectus and future filings.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should consider carefully the risks and uncertainties described below, together with all of the other information included in this prospectus as well as the risk factors included in Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended April 30, 2023 incorporated by reference into this prospectus, before making a decision to invest in our securities.

If any such risks actually occur, our business, platform, reputation, brand, results of operations, financial condition and prospects could be materially and adversely affected. In such an event, the market price of our securities could decline, and you could lose all or part of your investment. Please also read carefully the section below titled “Cautionary Note Regarding Forward-Looking Statements.”

Risks Related to this Offering

The sale or issuance of our Common Stock to Lincoln Park may cause dilution and the sale of the shares of Common Stock acquired by Lincoln Park, or the perception that such sales may occur, could cause the price of our Common Stock to fall.

On March 10, 2023, we entered into the Lincoln Park Purchase Agreement with Lincoln Park pursuant to which we have the right, but not the obligation, to sell to Lincoln Park up to $15,000,000 of shares of our Common Stock from time to time over a 36-month term beginning only after certain conditions set forth in the Lincoln Park Purchase Agreement have been satisfied, including that that the registration statement registering such shares for resale shall have been declared effective under the Securities Act. In accordance with the Lincoln Park Purchase Agreement, on March 13, 2023, we issued 100,000 shares of our Common Stock to Lincoln Park (the “Initial Commitment Shares”) as consideration for its commitment to purchase the Lincoln Park Shares under the Lincoln Park Purchase Agreement. As a result of Lincoln Park’s purchases cumulatively reaching an aggregate amount of $2,000,000 of Lincoln Park Shares, in accordance with the Lincoln Park Purchase Agreement, we will issue an additional 62,500 shares of our Common Stock to Lincoln Park as consideration for such purchases.

Under the applicable rules of Nasdaq, on January 17, 2024, we obtained shareholder approval to issue to Lincoln Park, pursuant to the Lincoln Park Purchase Agreement, shares of our Common Stock, including the Commitment Shares, which may exceed 19.99% of the shares of our Common Stock outstanding immediately prior to the execution of the Lincoln Park Purchase Agreement (the “Beneficial Ownership Cap”). Pursuant to the Lincoln Park Purchase Agreement, we may not direct Lincoln Park to purchase any shares of our Common Stock if those shares, when aggregated with all other shares of our Common Stock then beneficially owned by Lincoln Park (as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 13d-3 thereunder), would result in Lincoln Park and its affiliates beneficially owning more than 9.99% of the then total outstanding shares of Common Stock (the “Beneficial Ownership Limitation”). As of February 28, 2024, we have issued 2,864,522 shares to Lincoln Park, including the Initial Commitment Shares, receiving gross proceeds of approximately $1.2 million.

We generally have the right to control the timing and amount of any future sales of our shares to Lincoln Park. Additional sales of our Common Stock, if any, to Lincoln Park will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the shares of our Common Stock that may be available for us to sell pursuant to the Lincoln Park Purchase Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales of the Lincoln Park Shares to Lincoln Park by us could result in substantial dilution to the interests of other holders of our Common Stock. Additionally, the sale of a substantial number of the Lincoln Park Shares to Lincoln Park, or the anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales.

We may not have access to the full amount available under the Lincoln Park Purchase Agreement.

Under the Lincoln Park Purchase Agreement, we may, at our discretion from time to time over a 36-month period commencing after the satisfaction of certain conditions set forth in the Lincoln Park Purchase Agreement, subject to the Beneficial Ownership Limitation, on any single business day, direct Lincoln Park to purchase shares of our Common Stock in amounts up to 50,000 shares (subject to adjustment), subject to a maximum commitment by Lincoln Park of $750,000 per single regular purchase. Although the Lincoln Park Purchase Agreement provides that

we may sell up to $15,000,000 of our Common Stock to Lincoln Park, only 21,423,965 shares of our Common Stock are being offered under this prospectus, which represents the shares of our Common Stock which may be issued to Lincoln Park in the future under the Lincoln Park Purchase Agreement, if and when we sell shares of our Common Stock to Lincoln Park under the Lincoln Park Purchase Agreement. As a result, depending on the market prices of our Common Stock, we may not be able to sell the full $15,000,000 commitment amount contemplated by the Lincoln Park Purchase Agreement. For example, assuming that we sell all of the 21,423,965 Lincoln Park Shares being registered for resale under this prospectus at an average purchase price of $0.1164 per share (which was the closing price of our Common Stock on the Nasdaq Capital Market on February 28, 2024), our total gross proceeds would only be approximately $2,493,750. As of February 28, 2024, we have issued 2,864,522 shares to Lincoln Park, including the Initial Commitment Shares, receiving gross proceeds of approximately $1.2 million.

In the event that the market prices of our Common Stock increases, we may be able to issue and sell more than the 21,423,965 shares of our Common Stock to Lincoln Park in an effort to obtain up to the full $15,000,000 commitment amount contemplated by the Lincoln Park Purchase Agreement; provided in such case we will need to register for resale under the Securities Act such incremental additional shares of our Common Stock, which will require additional time, resources and cost to us. In addition, the issuance and sale of such additional shares could cause substantial dilution to our stockholders.

The extent we rely on Lincoln Park as a source of funding will depend on a number of factors including the prevailing market price of our Common Stock and the extent to which we are able to secure working capital from other sources. If obtaining sufficient funding from Lincoln Park were to prove unavailable or prohibitively dilutive, we will need to secure another source of funding in order to satisfy our working capital needs. Even if we sell all $15,000,000 under the Lincoln Park Purchase Agreement to Lincoln Park, we may still need additional capital to fully implement our business, operating and development plans. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, the consequences could have a material adverse effect on our business, operating results, financial condition and prospects.

Our management will have broad discretion over the use of the net proceeds from our sale of the Lincoln Park Shares to Lincoln Park and any cash exercise of the Warrants. You may not agree with how we use the proceeds and the proceeds may not be invested successfully.

Our management will have broad discretion as to the use of the net proceeds from our sale of the Lincoln Park Shares to Lincoln Park and any cash exercise of the Warrants, and we could use them for purposes other than those contemplated at the time of commencement of this offering. Accordingly, you will be relying on the judgment of our management with regard to the use of those net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that, pending their use, we may invest those net proceeds in a way that does not yield a favorable, or any, return for us. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flows.

We will need additional capital beyond the capital raised from the sale of the Lincoln Park Shares to Lincoln Park, and the sale of additional shares of our Common Stock, equity and/or debt securities could result in additional dilution to our shareholders.

Although the net proceeds of the sale of the Lincoln Park Shares to Lincoln Park, if any, are anticipated to be sufficient to achieve FDA clearance, which would allow us to market the MyoVista in the United States, there is no assurance that this would be the case and further funding may be required. We will need to raise additional capital beyond the capital raised in the IPO and from the sale of Lincoln Park Shares to Lincoln Park in order to support the sales launch of the MyoVista into the U.S., provide working capital and support further R&D. Such additional capital may be raised through a combination of private and public equity offerings, debt financings and collaborations, and strategic and licensing arrangements. To the extent that we raise additional capital through the issuance of our Common Stock, equity and/or convertible debt securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a holder of our Common Stock. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take certain actions, such as incurring debt, without prior approval, making capital expenditures or declaring dividends. If we raise additional funds through strategic partnerships and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or product or grant licenses on terms that are not favorable to us.

If we are unable to raise additional funds through equity or debt financing when needed, we may be required to delay, limit, reduce or terminate our product development, sales launch or marketing efforts or grant rights to develop and market product that we would otherwise prefer to develop and market ourselves.

Risks Related to Our Business and Industry

Interruptions in computing and data management cloud systems could impair the delivery of our cardiac monitoring services.

The success of our products and services will be dependent upon our ability to perform computing functions associated with our cardiac signal processing algorithms and data management. The diagnostic and monitoring functions rely on the uninterrupted availability of third-party cloud based computational and data management services. Availability of the cloud-based infrastructure is a critical link in our ability to deliver our services and could have a material adverse effect on our business and operating results. Furthermore, loss of data due to catastrophic events at the sites for these cloud-based computer systems could cause permanent harm to our customers. These adverse events associated with unavailability of our cloud based computational infrastructure could result in liability, claims and litigation against us for damages or injuries resulting from the disruption in service.

Our systems are also expected to be vulnerable to damage or interruption in cloud computational services from earthquakes, floods, fires, power loss, technical failures, terrorist attacks, computer viruses, break-ins, sabotage, and acts of vandalism. Despite any precautions that we may take, the occurrence of a natural disaster or other unanticipated problems could result in lengthy interruptions in these services.

Our proprietary data analytics engine may not operate properly, which could damage our reputation, give rise to claims against us or divert application of our resources from other purposes, any of which could harm our business and operating results.

The ECG data that is gathered through our products is governed AI-based ECG algorithms that are part of our service. The continuous development, maintenance and operation of our deep-learned backend data analytics engine is expensive and complex, and may involve unforeseen difficulties including material performance problems, undetected defects or errors. We may encounter technical obstacles, and it is possible that we may discover additional problems that prevent our proprietary algorithms from operating properly. We may also attempt to develop new capabilities and incorporate new technologies, including artificial intelligence, which could impact our data analytics platform’s performance. If our data analytics platform does not function reliably or fails to meet physician or payor expectations in terms of performance, physicians may stop prescribing our service and payors could attempt to cancel their contracts with us.

Any unforeseen difficulties we encounter in our existing or new software, cloud-based applications, telecommunication service providers, and analytics services, and any failure by us to identify and address them could result in loss of revenue or market share, diversion of development resources, injury to our reputation and increased service and maintenance costs. Correction of defects or errors could prove to be impossible or impracticable. The costs incurred in correcting any defects or errors may be substantial and could adversely affect our operating results.

USE OF PROCEEDS

We will not receive any of the proceeds from the Shares sold by the Selling Stockholders, other than any proceeds from any cash exercise of the Warrants. We will, however, receive proceeds from the sale of the Lincoln Park Shares directly to Lincoln Park pursuant to the Lincoln Park Purchase Agreement. We may receive up to $15,000,000 in aggregate gross proceeds under the Lincoln Park Purchase Agreement from any sales of the shares of our Common Stock we make to Lincoln Park pursuant to the Lincoln Park Purchase Agreement after the date of this prospectus. We have previously received $1,224,050 in aggregate gross proceeds from prior sales of 2,864,522 shares, including the Initial Commitment Shares, under the Lincoln Park Purchase Agreement. We estimate that the net proceeds to us from the sale of the Lincoln Park Shares to Lincoln Park pursuant to the Lincoln Park Purchase Agreement will be up to $2,493,750 assuming that we sell the full amount of Lincoln Park Shares offered by this prospectus and assuming an average purchase price of $0.1164 per share (which was the closing price of our Common Stock on the Nasdaq Capital Market on February 28, 2024), and after other estimated fees and expenses. Depending on the market prices of our Common Stock and other factors, we may sell more (subject to certain requirements) or fewer than all of the shares offered by this prospectus, in which case our net offering proceeds may be more or less. In addition, because we are not obligated to sell any shares of our Common Stock under the Lincoln Park Purchase Agreement, other than the Commitment Shares, the actual total offering amount and proceeds to us, if any, are not determinable at this time. There can be no assurance that we will receive any proceeds under or fully utilize the Lincoln Park Purchase Agreement. See “Plan of Distribution” elsewhere in this prospectus for more information. Any proceeds that we receive from such sales of the Lincoln Park Shares will be used for working capital and general corporate purposes, which may include acquisitions, investments in or licenses of complementary products, technologies or businesses, operating expenses and capital expenditures. Our management will retain broad discretion in the allocation of the net proceeds from any sale of the Lincoln Park Shares.

We may also receive cash proceeds equal to the total exercise price of the Warrants issued to Mount Sinai to the extent any of such Warrants are exercised for cash. The exercise price of the MTS Warrants is $0.5060 per share of Common Stock and the exercise price of the MTS Pre-Funded Warrants is $0.00001. The exercise price and the number of shares of Common Stock issuable upon exercise of the Warrants may be adjusted in certain circumstances, including stock splits, dividends or distributions, or other similar transactions. The Warrants contain a “cashless exercise” feature that allows the holders to exercise any of such Warrants without making a cash payment to us if there is not an effective registration statement covering the resale of the shares issuable upon exercise of such Warrants. There can be no assurance that any of the Warrants will be exercised by the Selling Stockholders at all. To the extent we receive proceeds from the cash exercise of the Warrants, we intend to use such proceeds for working capital and general corporate purposes, which may include acquisitions, investments in or licenses of complementary products, technologies or businesses, operating expenses and capital expenditures. Our management will retain broad discretion in the allocation of the net proceeds from any exercise of the Warrants for cash.

The Selling Stockholders will pay any underwriting discounts, selling commissions or transfer taxes incurred in disposing of the Shares and the expenses of any attorney or other advisor they decide to employ. We will bear all other costs, fees and expenses incurred in effecting the registration of the Shares covered by this prospectus. These may include, without limitation, all registration, filing, stock exchange fees, printing expenses, all fees and expenses of complying with applicable securities laws and the fees and disbursements of our counsel and of our independent accountants and reasonable fees.

MARKET FOR COMMON STOCK AND DIVIDEND POLICY

Our Common Stock is traded on the Nasdaq Capital Market under the symbol “HSCS.” The last reported sale price of our Common Stock on February 28, 2024 on the Nasdaq Capital Market was $0.1164 per share. As of February 28, 2024, there were 295 holders of record of our Common Stock.

We have never declared or paid any cash dividends on our capital stock. We currently intend to retain any future earnings to fund the development and expansion of our business, and therefore we do not anticipate paying cash dividends on our Common Stock in the foreseeable future. Any future determination to pay dividends will be at the discretion of our Board of Directors and will depend on our results of operations, financial condition, capital requirements, contractual restrictions and other factors deemed relevant by our Board of Directors.

SELLING STOCKHOLDERS TRANSACTIONS

Mount Sinai

On September 20, 2023, we entered into multiple definitive License Agreements with Mount Sinai to commercialize a range of AI-ECG algorithms covering a range of cardiovascular conditions developed by Mount Sinai as well as a memorandum of understanding for ongoing cooperation encompassing de-identified data access, on-going research, and the evaluation of the MyoVista. The License Agreements, of which there are eleven in total, cover rights to thirteen AI-ECG cardiovascular algorithms, two data science methods for use with ECG waveforms and three filed patents.

On November 15, 2023, we closed the transactions contemplated under the Mount Sinai Securities Purchase Agreement and the Licenses under the License Agreements, which became effective on that date. On November 16, 2023 and pursuant to the Mount Sinai Securities Purchase Agreement, we issued to Mount Sinai the following:

•        4,854,853 shares of Common Stock (the “Consideration Shares” and collectively with the MTS Warrants and the MTS Pre-Funded Warrants, the “MTS Securities”);

•        The MTS Pre-Funded Warrants to purchase up to 710,605 shares of Common Stock, with an exercise price per share of $0.00001, which warrants were issued in lieu of shares of Common Stock issuable to Mount Sinai to ensure that the number of shares of Common Stock held by Mount Sinai does not exceed the Beneficial Ownership Limitation; and

•        The MTS Warrants to purchase up to 914,148 shares of Common Stock, having an exercise price per share equal to $0.5060.

Registration rights related to the MTS Securities provide that on or prior to the date of one hundred and fifty days (150) days after the closing date, we shall prepare and file with the SEC a Registration Statement on Form S-1 (or such other form as applicable) covering the resale under the Securities Act of the MTS Securities issued to Mount Sinai, subject to any limitations imposed by the Nasdaq Rules.

Lincoln Park Transaction

General

On March 10, 2023, we entered into the Lincoln Park Purchase Agreement with Lincoln Park pursuant to which we have the right, but not the obligation, to sell to Lincoln Park up to $15,000,000 of the Purchase Shares from time to time over a 36-month term beginning only after certain conditions set forth in the Lincoln Park Purchase Agreement have been satisfied, including that the Lincoln Park Registration Statement shall have been declared effective under the Securities Act. In accordance with the Lincoln Park Purchase Agreement, on March 13, 2023, we issued the Initial Commitment Shares to Lincoln Park as consideration for its commitment to purchase the Purchase Shares under the Lincoln Park Purchase Agreement. As a result of Lincoln Park’s purchases cumulatively reaching an aggregate amount of $2,000,000 of Purchase Shares, in accordance with the Lincoln Park Purchase Agreement, we will issue an additional 62,500 shares of our Common Stock to Lincoln Park as consideration for such purchases.

Concurrently with entering into the Lincoln Park Purchase Agreement, we entered into a registration rights agreement with Lincoln Park (the “Registration Rights Agreement”) pursuant to which we agreed to register the resale of the Purchase Shares and Commitment Shares that have been and may be issued to Lincoln Park under the Lincoln Park Purchase Agreement pursuant to the Lincoln Park Registration Statement. On March 29, 2023, we filed with the SEC the Lincoln Park Registration Statement registering the resale of the Purchase Shares and Commitment Shares that have been and may be issued to Lincoln Park under the Lincoln Park Purchase Agreement, and the SEC declared the Lincoln Park Registration Statement effective on April 10, 2023.

As of February 28, 2024, we have issued 2,864,522 shares to Lincoln Park, including the Initial Commitment Shares, receiving gross proceeds of approximately $1.2 million.

We may, from time to time and at our sole discretion, subject to the Beneficial Ownership Limitation, direct Lincoln Park to purchase shares of our Common Stock upon the satisfaction of certain conditions set forth in the Lincoln Park Purchase Agreement at a purchase price per share based on the market price of our Common Stock at the time of sale as computed under the Lincoln Park Purchase Agreement. Lincoln Park may not assign or transfer its rights and obligations under the Lincoln Park Purchase Agreement.

On January 17, 2024, we obtained shareholder approval to issue to Lincoln Park, pursuant to the Lincoln Park Purchase Agreement, shares of our Common Stock, including the Commitment Shares, which exceed 1,927,022 shares, which was then equal to 19.99% of the shares of our Common Stock outstanding immediately prior to the execution of the Lincoln Park Purchase Agreement. The Lincoln Park Purchase Agreement also prohibits us from directing Lincoln Park to purchase any shares of our Common Stock if those shares, when aggregated with all other shares of our Common Stock then beneficially owned by Lincoln Park, would result in Lincoln Park and its affiliates’ exceeding the Beneficial Ownership Limitation.

Purchase of Shares under the Purchase Agreement

Regular Purchases

After the Commencement Date, on any business day selected by us, we may direct Lincoln Park to purchase up to 50,000 shares of our Common Stock on such business day (or the purchase date), which we refer to as a Regular Purchase, provided that the closing sale price of our Common Stock on Nasdaq is not below $0.10 on the applicable purchase date, and provided, further, that (i) a Regular Purchase shall be increased to up to 75,000 shares if the closing sale price of our Common Stock on Nasdaq is not below $0.75 on the applicable purchase date, (ii) a Regular Purchase shall be increased to up to 100,000 shares if the closing sale price of our Common Stock on Nasdaq is not below $1.00 on the applicable purchase date, (iii) a Regular Purchase shall be increased to up to 150,000 shares if the closing sale price of our Common Stock on Nasdaq is not below $2.00 on the applicable purchase date, (iv) a Regular Purchase shall be increased to up to 200,000 shares if the closing sale price of our Common Stock on Nasdaq is not below $2.50 on the applicable purchase date. However, we may not direct Lincoln Park to purchase more than $750,000 in shares under any single Regular Purchase.

The purchase price per share for each such Regular Purchase will be equal to the lesser of:

•        the lowest sale price for our Common Stock on the purchase date of such shares; and

•        the average of the three lowest closing sale prices for our Common Stock during the ten (10) consecutive business days prior to the purchase date of such shares.

Accelerated Purchases

We may also direct Lincoln Park, subject to the Beneficial Ownership Limitation, on any business day on which we have properly submitted a Regular Purchase notice to purchase an additional amount of our Common Stock (an “Accelerated Purchase”) of up to the lesser of:

•        three times the number of shares purchased pursuant to such Regular Purchase; or

•        30% of the aggregate shares of our Common Stock traded during all or, if certain trading volume or market price thresholds specified in the Lincoln Park Purchase Agreement are crossed on the applicable Accelerated Purchase date, the portion of the normal trading hours on the applicable Accelerated Purchase date prior to such time that any one of such thresholds is crossed, which period of time on the applicable Accelerated Purchase date (the “Accelerated Purchase Measurement Period”).

The purchase price per share for each such Accelerated Purchase will be equal to the lesser of 97% of:

•        the volume-weighted average price of our Common Stock during the applicable Accelerated Purchase Measurement Period on the applicable Accelerated Purchase date; and

•        the closing sale price of our Common Stock on the applicable Accelerated Purchase date.

Additional Accelerated Purchases

We may also direct Lincoln Park, subject to the Beneficial Ownership Limitation, on any business day on which an Accelerated Purchase has been completed and all of the shares to be purchased thereunder have been properly delivered to Lincoln Park in accordance with the Purchase Agreement, to purchase an additional amount of our Common Stock (an “Additional Accelerated Purchase”), of up to the lesser of:

•        three times the number of shares purchased pursuant to such Regular Purchase; or

•        30% of the aggregate shares of our Common Stock traded during a certain portion of the normal trading hours on the applicable Additional Accelerated Purchase date as determined in accordance with the Purchase Agreement, which period of time on the applicable Additional Accelerated Purchase date we refer to as the “Additional Accelerated Purchase Measurement Period”.

We may, in our sole discretion, subject to the Beneficial Ownership Limitation, submit multiple Additional Accelerated Purchase notices to Lincoln Park on a single Accelerated Purchase date, provided that all prior Accelerated Purchases and Additional Accelerated Purchases (including those that have occurred earlier on the same day) have been completed and all of the shares to be purchased thereunder have been properly delivered to Lincoln Park in accordance with the Purchase Agreement.

The purchase price per share for each such Additional Accelerated Purchase will be equal to the lesser of 97% of:

•        the volume weighted average price of our Common Stock during the applicable Additional Accelerated Purchase Measurement Period on the applicable Additional Accelerated Purchase date; and

•        the closing sale price of our Common Stock on the applicable Additional Accelerated Purchase date.

In the case of the Regular Purchases, Accelerated Purchases and Additional Accelerated Purchases, the purchase price per share will be equitably adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction occurring during the business days used to compute the purchase price.

Other than the Beneficial Ownership Limitation and as described above, there are no trading volume requirements or restrictions under the Purchase Agreement, and we will control the timing and amount of any sales of our Common Stock to Lincoln Park.

Suspension Events

Suspension Events under the Lincoln Park Purchase Agreement include the following:

•        the effectiveness of the registration statement of which this prospectus forms a part lapses for any reason (including, without limitation, the issuance of a stop order), or any required prospectus is unavailable for the resale by Lincoln Park of our Common Stock offered hereby, and such lapse or unavailability continues for a period of 10 consecutive business days or for more than an aggregate of 30 business days in any 365-day period, but excluding a lapse or unavailability where (i) we terminate a registration statement after Lincoln Park has confirmed in writing that all of the shares of our Common Stock covered thereby have been resold or (ii) we supersede one registration statement with another registration statement, including (without limitation) by terminating a prior registration statement when it is effectively replaced with a new registration statement covering the shares of our Common Stock covered by the Lincoln Park Purchase Agreement (provided in the case of this clause (ii) that all of the shares of our Common Stock covered by the superseded (or terminated) registration statement that have not theretofore been resold are included in the superseding (or new) registration statement);

•        suspension by our principal market of our Common Stock from trading for a period of one business day;

•        the de-listing of our Common Stock from the Nasdaq Capital Market, our principal market, provided, our Common Stock is not immediately thereafter trading on the New York Stock Exchange, the Nasdaq Global Market, the Nasdaq Global Select Market, the NYSE American, the NYSE Arca, the OTC Bulletin Board, the OTCQX or the OTCQB operated by the OTC Markets Group, Inc. (or nationally recognized successor to any of the foregoing);

•        the failure for any reason by our transfer agent to issue purchased shares of our Common Stock to Lincoln Park within two business days after the purchase date, Accelerated Purchase date or Additional Accelerated Purchase date, as applicable, on which Lincoln Park is entitled to receive such purchased shares;

•        any breach of the representations, warranties, covenants or other terms or conditions contained in the Lincoln Park Purchase Agreement or the Lincoln Park Registration Rights Agreement that has or could have a Material Adverse Effect (as defined in the Lincoln Park Purchase Agreement) and, in the case of a breach of a covenant that is reasonably curable, that is not cured within a period of at least five business days;

•        our Common Stock ceases to be DTC authorized and ceases to participate in the DWAC/FAST systems; or

•        any voluntary or involuntary participation or threatened participation in insolvency or bankruptcy proceedings by or against us.

Lincoln Park does not have the right to terminate the Lincoln Park Purchase Agreement upon any of the suspension events set forth above; however, the Lincoln Park Purchase Agreement will automatically terminate upon initiation of insolvency or bankruptcy proceedings by or against us. During any suspension event, or if any event that, after notice and/or lapse of time, would reasonably be expected to become a suspension event, has occurred and is continuing, all of which are outside of Lincoln Park’s control, we may not direct Lincoln Park to purchase any shares of our Common Stock under the Lincoln Park Purchase Agreement.

Our Termination Rights

We have the unconditional right, at any time, for any reason and without any payment or liability to us, to give notice to Lincoln Park to terminate the Purchase Agreement.

No Short-Selling or Hedging by Lincoln Park

Lincoln Park has agreed that neither it nor any of its affiliates shall engage in any direct or indirect short-selling or hedging of our Common Stock during any time prior to the termination of the Lincoln Park Purchase Agreement.

Prohibitions on Variable Rate Transactions

Subject to specified exceptions included in the Lincoln Park Purchase Agreement, we are limited in our ability to enter into specified variable rate transactions during the term of the Lincoln Park Purchase Agreement. Such transactions include, among others, the issuance of convertible securities with a conversion or exercise price that is based upon or varies with the trading price of our Common Stock after the date of issuance, the issuance of securities with embedded anti-dilution provisions, the issuance of securities with an embedded put or call right or at a price subject to being reset after the initial issuance contingent on our business or market performance.

Effect of Performance of the Purchase Agreement on our Stockholders

All shares registered in this offering that have been or may be issued or sold by us to Lincoln Park under the Lincoln Park Purchase Agreement are expected to be freely tradable. Such shares registered in this offering may be sold over a period of up to approximately 26 months commencing on the date of this prospectus. The sale by Lincoln Park of a significant amount of shares registered in this offering at any given time could cause the market price of our Common Stock to decline and be highly volatile. Sales of our Common Stock to Lincoln Park, if any, will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the additional shares of our Common Stock that may be available for us to sell pursuant to the Purchase Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to Lincoln Park by us under the Lincoln Park Purchase Agreement may result in substantial dilution to the interests of other holders of our Common Stock. In addition, if we sell a substantial number of shares to Lincoln Park under the Lincoln Park Purchase Agreement, or if investors expect that we will do so, the actual sales of shares or the mere existence of our arrangement with Lincoln Park may make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect such sales. However, we have the right to control the timing and amount of any additional sales of our shares to Lincoln Park and the Lincoln Park Purchase Agreement may be terminated by us at any time at our discretion without any cost to us.

Pursuant to the terms of the Lincoln Park Purchase Agreement, we have the right, but not the obligation, subject to the Beneficial Ownership Limitation, to direct Lincoln Park to purchase up to $15,000,000 of our Common Stock, exclusive of the Initial Commitment Shares issued to Lincoln Park on the date of the Lincoln Park Purchase Agreement. The Lincoln Park Purchase Agreement prohibits us from issuing or selling to Lincoln Park under the Lincoln Park Purchase Agreement any shares of our Common Stock if those shares, when aggregated with all other shares of our Common Stock then beneficially owned by Lincoln Park, would exceed the Beneficial Ownership Limitation. On January 17, 2024, we obtained shareholder approval to issue to Lincoln Park, pursuant to the Lincoln Park Purchase Agreement, shares of our Common Stock, including the Commitment Shares, which may exceed the Beneficial Ownership Cap.

The following table sets forth the amount of gross proceeds we would receive from Lincoln Park from our sale of shares to Lincoln Park under the Purchase Agreement at varying purchase prices:

____________

(1)      Represents the total number of shares of our Common Stock that we would have sold under the Purchase Agreement (excluding the Commitment Shares) at the corresponding assumed average purchase price set forth in the adjacent column, up to the aggregate purchase price of $13,775,950 (the remaining amount available under the Lincoln Park Purchase Agreement as of February 28, 2024), if available, without regard for the Beneficial Ownership Limitation, and up to the maximum number of Lincoln Park Shares being registered pursuant to this prospectus.

(2)      The denominator is based on 65,161,630 shares outstanding as of February 28, 2024, adjusted to include the issuance of (i) the Commitment Shares issued to Lincoln Park upon the execution of the Lincoln Park Purchase Agreement and (ii) the number of shares set forth in the adjacent column that we would have sold to Lincoln Park, assuming the average purchase price in the first column. The numerator is based on the number of shares issuable under the Lincoln Park Purchase Agreement (that are the subject of this offering up to the maximum number of Lincoln Park Shares being registered pursuant to this prospectus) at the corresponding assumed average purchase price set forth in the first column.

(3)      The closing sale price of our Common Stock on February 28, 2024.

John Q. Adams

In April 2020, we entered into the $1M Loan and Security Agreement, with FRV and Adams (a former director of our Company). Each of FRV and Adams committed to lend a principal amount of $500,000, totaling $1 million, evidenced by secured, non-convertible promissory notes that we refer to as the $1M Notes. The loan was drawn in three installments of $300,000 upon execution of the $1M Loan and Security Agreement, $350,000 in July 2020 and $350,000 in September 2020. The loan accrued interest at a rate of 12% per annum, compounded annually, which is payable at maturity. We were also required to pay default interest at a rate of 18% per annum, compounded annually, on any unpaid amounts due at maturity until the loan amounts are fully repaid. The loan is secured by substantially all of the Company’s assets and intellectual property.

The loan had an original maturity date of September 30, 2021, which was amended on September 30, 2021, making the note repayable on demand. The loan was amended on November 3, 2021, extending the maturity to September 30, 2022; further amended in May 2022 to extend the maturity date to September 30, 2023; amended again in January 2023 to (i) further extend the maturity date of the portion of the $1M Notes issued to one lender (in the principal amount of $0.5 million) to March 31, 2024 and (ii) further extend the maturity date of the remaining portion of the $1M Notes issued to the other lender (in the principal amount of $0.5 million) to September 30, 2024. The $1M Loan and Security Agreement was further amended in September 2023 to extend the interest maturity date to one lender to December 31, 2023. In October 2023, we issued additional $1M Lender Warrants to purchase 200,000 shares of our Common Stock to lenders of the $1M Notes as consideration for the extension of the interest maturity date

to one lender. On November 16, 2023, we entered into the Adams Warrant Amendment, amending the $1M Lender Warrants owned by Adams to reduce the exercise price of an aggregate of 107,575 $1M Lender Warrants to $0.16 per share. The exercise prices of the $1M Lender Warrants range from $0.16 to $2.89 per share as of February 28, 2024.

Matthews Southwest Holdings, Inc.

On August 12, 2021, we issued a note for the amount of $500,000 to Matthews, a beneficial owner owning more than 5% of our Common Stock. The maturity date of this note, as amended, was November 30, 2021. This note has been repaid and there are no further obligations owed by our Company. In connection with the issuance of this note, we also issued 10,101 shares of our Common Stock as a facility fee for the note to Matthews.

On September 7, 2023, we entered into the MSW Note with Matthews. The MSW Note provided for an unsecured drawdown loan of up to $1,000,000. As of November 14, 2023, the Company had drawn $500,000 under the MSW Note and issued 1,000,000 Existing MSW Warrants to purchase shares of Common Stock in lieu of certain fees payable under the MSW Note.

On November 15, 2023, we entered into the Note Conversion Letter Agreements with MSW and Adams (collectively, the “Lenders”). On November 16, 2023, pursuant to the Note Conversion Letter Agreements, in consideration for the conversion of the aggregate principal and interest amount due under the Notes, we: (1) issued an aggregate of 6,781,288 shares of Common Stock to the Lenders, comprised of (a) 3,125,000 shares of Common Stock to MSW and (b) 3,656,288 shares of Common Stock issued to Adams; (2) entered into the MSW Warrant Amendment with MSW, amending the Existing MSW Warrants to reduce the exercise price of an aggregate of 1,000,000 Existing MSW Warrants to $0.16 per share; and (3) entered into the Adams Warrant Amendment, amending the $1M Lender Warrants owned by Adams to reduce the exercise price of an aggregate of 107,575 $1M Lender Warrants to $0.16 per share. Except as expressly set forth in the MSW Warrant Amendment and the Adams Warrant Amendment, the terms and provisions of the warrants held by the Lenders shall remain in full force and effect.

SELLING STOCKHOLDERS

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

We have prepared this prospectus to allow the Selling Stockholders or their successors, assignees or other permitted transferees to sell or otherwise dispose of, from time to time, up to 34,684,859 shares of our Common Stock, which consist of: (i) 4,854,853 Mount Sinai Shares, (ii) 710,605 shares of Common Stock issuable upon the exercise of the MTS Pre-Funded Warrants, (iii) 914,148 shares of Common Stock issuable upon the exercise of the MTS Warrants, (iv) up to 21,423,965 Lincoln Park Shares issuable to Lincoln Park from time to time over approximately the next 26 months, at our sole discretion, in accordance with the Lincoln Park Purchase Agreement, (v) 3,656,288 Adams Shares issued to Adams pursuant to the Adams Note Conversion Letter Agreement, and (vi) 3,125,000 Matthews Shares issued to Matthews pursuant to the Matthews Note Conversion Letter Agreement.

The MTS Pre-Funded Warrants were exercisable by Mount Sinai immediately upon issuance, will survive until they are exercised in full and have an exercise price, which was pre-funded on September 20, 2023, of $0.00001 per share of Common Stock, subject to adjustment for stock splits, reverse stock splits, stock dividends and similar transactions. The MTS Warrants have an exercise price per share equal to $0.5060. Under the terms of the MTS Warrants, Mount Sinai may not exercise such MTS Warrants to the extent such exercise would cause Mount Sinai, together with its affiliates, to beneficially own a number of shares of our Common Stock which would exceed 4.99% of our then outstanding Common Stock following such exercise, excluding for purposes of such determination Common Stock issuable upon exercise of such MTS Warrants which have not been exercised. Under the terms of the MTS Pre-Funded Warrants, Mount Sinai may not exercise such Mount Sinai Pre-Funded Warrant to the extent such exercise would cause Mount Sinai, together with its affiliates, to beneficially own a number of shares of Common Stock which would exceed 9.99% of our then outstanding Common Stock following such exercise, excluding for purposes of such determination Common Stock issuable upon exercise of such Mount Sinai Pre-Funded Warrant which have not been exercised.

The Shares were issued or will be issuable to the Selling Stockholders in reliance on the exemption from securities registration in Section 4(a)(2) under the Securities Act and Rule 506 promulgated thereunder or Regulation S, to the extent applicable.

The shares of Common Stock to be offered by the Selling Stockholders are “restricted” securities under applicable federal and state securities laws and are being registered under the Securities Act to give the Selling Stockholders the opportunity to sell these shares publicly. The registration of these shares does not require that any of the shares be offered or sold by the Selling Stockholders. Subject to these resale restrictions, the Selling Stockholders may from time to time offer and sell all or a portion of their shares indicated below in privately negotiated transactions or on the Nasdaq Capital Market or any other market on which our Common Stock may subsequently be listed.

The registered shares may be sold directly or through brokers or dealers, or in a distribution by one or more underwriters on a firm commitment or best effort basis. To the extent required, the names of any agent or broker-dealer and applicable commissions or discounts and any other required information with respect to any particular offering will be set forth in a prospectus supplement. See the section of this prospectus entitled “Plan of Distribution”. The Selling Stockholders and any agents or broker-dealers that participate with the Selling Stockholders in the distribution of registered shares may be deemed to be “underwriters” within the meaning of the Securities Act, and any commissions received by them and any profit on the resale of the registered shares may be deemed to be underwriting commissions or discounts under the Securities Act.

No estimate can be given as to the amount or percentage of Common Stock that will be held by the Selling Stockholders after any sales made pursuant to this prospectus because the Selling Stockholders are not required to sell any of the Shares being registered under this prospectus. The following table assumes that the Selling Stockholders will sell all of the Shares listed in this prospectus.

Unless otherwise indicated in the footnotes below, no Selling Stockholder has had any material relationship with us or any of our affiliates within the past three years other than as a security holder.

We have prepared this table based on written representations and information furnished to us by or on behalf of the Selling Stockholders or information available to us. Since the date on which the Selling Stockholders provided this information, the Selling Stockholders may have sold, transferred or otherwise disposed of all or a portion of the

shares of Common Stock in a transaction exempt from the registration requirements of the Securities Act. Unless otherwise indicated in the footnotes below, we believe that: (1) none of the Selling Stockholders are broker-dealers or affiliates of broker-dealers, (2) no Selling Stockholder has direct or indirect agreements or understandings with any person to distribute their Shares, and (3) the Selling Stockholders have sole voting and investment power with respect to all Shares beneficially owned, subject to applicable community property laws. To the extent any Selling Stockholder identified below is, or is affiliated with, a broker-dealer, it could be deemed, individually but not severally, to be an “underwriter” within the meaning of the Securities Act. Information about the Selling Stockholders may change over time. Any changed information will be set forth in supplements to this prospectus, if required.

The following table sets forth information with respect to the beneficial ownership of our Common Stock held, as of February 28, 2024, by the Selling Stockholders and the number of Shares being registered hereby and information with respect to shares to be beneficially owned by the Selling Stockholders after completion of the offering of the shares for resale. We have determined beneficial ownership in accordance with the rules of the SEC. The inclusion of any shares in this table does not constitute an admission of beneficial ownership by the persons named below. The percentages in the following table reflect the shares beneficially owned by the Selling Stockholders as a percentage of the total number of shares of Common Stock outstanding as of February 28, 2024. As of such date, 65,161,630 shares of Common Stock were outstanding.

____________

*        Denotes less than 1%

(1)      Beneficial ownership is determined in accordance with Rule 13d-3 of the Exchange Act. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of Common Stock subject to the warrants, options and other convertible securities held by that person that are currently exercisable or exercisable within 60 days (of February 28, 2024) are deemed outstanding. Shares subject to warrants, options and other convertible securities, however, are not deemed outstanding for the purpose of computing the percentage ownership of any other person.

(2)      We do not know when or in what amounts a Selling Stockholder may offer shares for sale. The Selling Stockholders may choose not to sell any or all of the shares offered by this prospectus. Because the Selling Stockholders may offer all or some of the Shares pursuant to this offering, we cannot estimate the number of the Shares that will be held by the Selling Stockholders after completion of the offering. However, for purposes of this table, we have assumed that, after completion of the offering, all of the Shares covered by this prospectus will be sold by the Selling Stockholders and that the Selling Stockholders do not acquire beneficial ownership of any additional shares.

(3)      Josh Scheinfeld and Jonathan Cope, the Managing Members of Lincoln Park Capital, LLC, are deemed to be beneficial owners of all of the shares of Common Stock owned by Lincoln Park. Messrs.

PLAN OF DISTRIBUTION

Pursuant to this prospectus, (i) we are registering the shares of our Common Stock previously issued to certain Selling Stockholders, and the shares of our Common Stock issuable upon exercise of the Warrants previously issued to certain Selling Stockholders to permit the resale of these shares of Common Stock by the holders of the Shares and the Warrants from time to time after the date of this prospectus, and (ii) we are offering up to 21,423,965 shares of our Common Stock that may be issued to Lincoln Park pursuant to the Lincoln Park Purchase Agreement.

We will not receive any of the proceeds from the Shares sold by the Selling Stockholders, other than any proceeds from any cash exercise of the Warrants. We will, however, receive proceeds from the sale of the Lincoln Park Shares directly to Lincoln Park pursuant to the Lincoln Park Purchase Agreement. We will bear all fees and expenses incident to our obligation to register the shares of Common Stock.

General

The Selling Stockholders may sell all or a portion of the shares of our Common Stock beneficially owned by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of our Common Stock are sold through underwriters or broker-dealers, the Selling Stockholders will be responsible for underwriting fees, discounts or commissions or agent’s commissions. The shares of our Common Stock may be sold by the Selling Stockholders in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. The Selling Stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. These sales may be effected in transactions, which may involve cross or block transactions:

•        on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;

•        in the over-the-counter market;

•        in transactions otherwise than on these exchanges or systems or in the over-the-counter market;

•        through the writing of options, whether such options are listed on an options exchange or otherwise;

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

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

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

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

•        in privately negotiated transactions;

•        in short sales;

•        through the distribution of our Common Stock by any Selling Stockholder to its partners, members or stockholders;

•        through one or more underwritten offerings on a firm commitment or best efforts basis;

•        in sales pursuant to Rule 144;

•        whereby broker-dealers may agree with any Selling Stockholders to sell a specified number of such shares at a stipulated price per share;

•        in a combination of any such methods of sale; and

•        in any other method permitted pursuant to applicable law.

If any Selling Stockholders effect such transactions by selling shares of our Common Stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the Selling Stockholders or commissions from purchasers of the shares of our Common Stock for whom they may act as agent or to whom they may sell as principal (which discounts,

concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of our Common Stock or otherwise, the Selling Stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of Common Stock in the course of hedging in positions they assume. The Selling Stockholders may also sell shares of Common Stock short and deliver shares of Common Stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The Selling Stockholders may also loan or pledge shares of Common Stock to broker-dealers that in turn may sell such shares. The Selling Stockholders may pledge or grant a security interest in some or all of the shares of Common Stock or Warrants owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending, if necessary, the list of Selling Stockholders to include the pledgee, transferee or other successors in interest as Selling Stockholders under this prospectus. The Selling Stockholders also may transfer and donate the shares of Common Stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The Selling Stockholders, individually and not severally, and any broker-dealer participating in the distribution of the shares of Common Stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of Common Stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of Common Stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the Selling Stockholders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers. The Selling Stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares of Common Stock against certain liabilities, including liabilities arising under the Securities Act.

Under the securities laws of some states, the shares of Common Stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

The aggregate proceeds to the Selling Stockholders from the sale of the Common Stock offered will be the purchase price of the Common Stock less discounts or commissions, if any. The Selling Stockholders reserve the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of Common Stock to be made directly or through agents. There can be no assurance that any Selling Stockholder will sell any or all of the shares of Common Stock registered pursuant to the registration statement of which this prospectus forms a part.

The Selling Stockholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of Common Stock by the Selling Stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of Common Stock to engage in market-making activities with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person or entity to engage in market-making activities with respect to the shares of Common Stock.

We will incur costs, fees and expenses in effecting the registration of the Shares covered by this prospectus, estimated to be approximately $41,000 in total, including, without limitation, all registration, filing, stock exchange fees, printing expenses, all fees and expenses of complying with applicable securities laws and the fees and disbursements of our counsel and of our independent registered public accounting firm and reasonable fees, provided, however, that a Selling Stockholder will pay all underwriting discounts, selling commissions or transfer taxes, if any. We will indemnify the Selling Stockholders against certain liabilities, including certain liabilities arising under the Securities Act or the Exchange Act. We may be indemnified by certain of the Selling Stockholders against certain liabilities, including certain liabilities arising under the Securities Act or the Exchange Act, that may arise from any written information furnished to us by a Selling Stockholder specifically for use in this prospectus.

Once sold under the registration statement, of which this prospectus forms a part, the shares of Common Stock will be freely tradable in the hands of persons other than our affiliates.

Lincoln Park Transaction

We may, from time to time and at our sole discretion, subject to the Beneficial Ownership Limitation, direct Lincoln Park to purchase shares of our Common Stock in amounts up to 50,000 shares on any single business day, subject to a maximum of $750,000 per purchase. In addition, upon notice to Lincoln Park, we may, from time to time and at our sole discretion, subject to the Beneficial Ownership Limitation, direct Lincoln Park to purchase additional shares of our Common Stock in “accelerated purchases,” and/or “additional accelerated purchases” as set forth in the Lincoln Park Purchase Agreement and described above in the section captioned “Selling Stockholders Transactions”. The purchase price per share is based on the market price of our Common Stock at the time of sale as computed under the Lincoln Park Purchase Agreement. Lincoln Park may not assign or transfer its rights and obligations under the Purchase Agreement. See “Selling Stockholders Transactions — Lincoln Park Transaction — Purchase of Shares under the Purchase Agreement.”

Lincoln Park is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act.

We will pay the expenses incident to the registration under the Securities Act of the offer and sale of the shares covered by this prospectus to Lincoln Park. We have agreed to indemnify Lincoln Park and certain other persons against certain liabilities in connection with the offering of shares of our Common Stock offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Lincoln Park has agreed to indemnify us against liabilities under the Securities Act that may arise from certain written information furnished to us by Lincoln Park specifically for use in this prospectus or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities.

Lincoln Park has represented to us that at no time prior to the Lincoln Park Purchase Agreement has Lincoln Park or its agents, representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any short sale (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of our Common Stock or any hedging transaction, which establishes a net short position with respect to our Common Stock. Lincoln Park agreed that during the term of the Lincoln Park Purchase Agreement, it, its agents, representatives or affiliates will not enter into or effect, directly or indirectly, any of the foregoing transactions.

We have advised Lincoln Park that it is required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes Lincoln Park, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities offered by this prospectus.

This offering of the Lincoln Park Shares will terminate on the date that all of the Lincoln Park Shares offered by this prospectus have been sold to Lincoln Park.

DESCRIPTION OF OUR SECURITIES

General

The following description summarizes the terms of our securities and certain provisions of our Certificate of Formation and our Bylaws. As it is only a summary, it does not contain all the information that may be important to you. For a complete description, you should refer to our Certificate of Formation and Bylaws, as in effect as of the date of filing with the SEC of this prospectus, the forms of which are included as exhibits to the registration statement of which this prospectus forms a part.

Our purpose is to engage in any lawful act or activity for which corporations may now or hereafter be organized under the TBOC. Our authorized capital stock consists of five hundred million (500,000,000) shares of Common Stock, par value $0.001 per share, and twenty million (20,000,000) shares of preferred stock, or Preferred Stock, par value $0.001 per share of which, as of February 28, 2024, there were 65,161,630 shares of Common Stock outstanding and held of record by 295 shareholders and 380,440 shares of Series C Preferred Stock outstanding that, as of such date, were convertible into 6,483,709 shares of Common Stock and held of record by 64 shareholders. Of our authorized Preferred Stock, six hundred thousand (600,000) shares have been designated as Series C Preferred Stock, having a par value of $0.001 per share, of which 380,440 were outstanding as of February 28, 2024. Unless our Board of Directors determines otherwise, we have and will continue to issue all shares of our capital stock in uncertificated form.

Common Stock

Holders of our Common Stock are entitled to one vote for each share held of record on all matters on which shareholders are entitled to vote generally, including the election or removal of directors, subject to certain limitations. The holders of our Common Stock do not have cumulative voting rights in the election of directors. Upon our liquidation, dissolution or winding up and after payment in full of all amounts required to be paid to creditors and to the holders of preferred stock having liquidation preferences, if any, the holders of our Common Stock will be entitled to receive pro rata our remaining assets available for distribution on a pro rata basis. Holders of our Common Stock do not have preemptive, subscription, redemption or conversion rights. The Common Stock will not be subject to further calls or assessment by us. There will be no redemption or sinking fund provisions applicable to the Common Stock. All outstanding shares of our Common Stock are fully paid and non-assessable. The rights, powers, preferences and privileges of holders of our Common Stock will be subject to those of the holders of any shares of our Preferred Stock, including any Preferred Stock we may authorize and issue in the future.

As a Texas corporation, we are subject to certain restrictions on dividends under the TBOC. Generally, a Texas corporation may pay dividends to its shareholders out of its surplus (the excess of its assets over its liabilities and stated capital) unless the dividend would render the corporation insolvent.

The declaration, amount and payment of any future dividends will be at the sole discretion of our Board of Directors. Our Board of Directors may take into account general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications on the payment of dividends by us to our shareholders.

We currently expect to retain all future earnings for use in the operation and expansion of our business and have no current plans to pay dividends.

Preferred Stock

Our Certificate of Formation authorizes our Board of Directors to establish one or more series of Preferred Stock (including convertible Preferred Stock). Unless required by law or by the TBOC, the authorized shares of Preferred Stock will be available for issuance without further action by our shareholders.

Our Board of Directors will be able to determine, with respect to any series of Preferred Stock, the powers including preferences and relative participations, optional or other special rights, and the qualifications, limitations or restrictions thereof, of that series, including, without limitation:

•        the designation of the series;

•        the number of shares of the series, which our Board of Directors may, except where otherwise provided in the preferred stock designation, increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares then outstanding);

•        whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series;

•        the dates at which dividends, if any, will be payable;

•        the redemption rights and price or prices, if any, for shares of the series;

•        the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series;

•        the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of the Company;

•        whether the shares of the series will be convertible into shares of any other class or series, or any other security, of the Company or any other corporation and, if so, the specification of the other class or series or other security, the conversion price or prices or rate or rates, any rate adjustments, the date or dates as of which the shares will be convertible and all other terms and conditions upon which the conversion may be made;

•        restrictions on the issuance of shares of the same series or of any other class or series; and

•        the voting rights, if any, of the holders of the series.

We will be able to issue a series of Preferred Stock that could, depending on the terms of the series, impede or discourage an acquisition attempt or other transaction that some, or a majority, of the holders of our Common Stock might believe to be in their best interests or in which the holders of our Common Stock might receive a premium for their Common Stock over the market price of the Common Stock. In addition, the issuance of Preferred Stock may adversely affect the rights of holders of our Common Stock by restricting dividends on the Common Stock, diluting the voting power of the Common Stock or subordinating the liquidation rights of the Common Stock. As a result of these or other factors, the issuance of Preferred Stock may have an adverse impact on the market price of our Common Stock.

Series C Preferred Stock

As of February 28, 2024, there were 380,440 shares of Series C Preferred Stock outstanding that, as of such date, were convertible into 6,483,709 shares of Common Stock. As of February 28, 2024, there were no shares of Series A Preferred Stock or Series B Preferred Stock outstanding.

The Series C Preferred Stock was issued from April 2019 to October 2020 to accredited investors and has a liquidation preference to the Common Stock. As of February 28, 2024, the liquidation preference was approximately $9.5 million. Any amendment to, or waiver of rights of the Series C Preferred Stock must include the consent of FRV, so long as FRV holds at least 71,000 shares of Series C Preferred Stock. Additionally, pursuant to a letter agreement entered into by and between the Company and FRV on April 10, 2019, for so long as FRV holds at least 71,000 shares of Series C Preferred Stock, it is entitled to appoint a member of the Board of Directors as well as a board observer (the “Appointment Rights”). As of February 28, 2024, FRV has not exercised its Appointment Rights.

Voting and Dividends

The holders of the shares of the Series C Preferred Stock have voting rights equal to an equivalent number of shares of the Common Stock into which such shares of Series C Preferred Stock are convertible and vote together as one class with the Common Stock.

The holders of the Series C Preferred Stock are entitled to receive dividends at an annual rate of $1.50 per share. Such dividends shall accrue and are payable out of funds legally available, are payable only when and if declared by the Board of Directors and are noncumulative. The Company is not permitted to declare, pay or set aside any dividends on shares of any other class or series of capital stock of the Company (other than dividends on shares of the Common Stock payable in shares of Common Stock) unless the holders of the shares of the Series C Preferred Stock then outstanding first receive, or simultaneously receive, a dividend on each outstanding share of the Series C Preferred Stock in an amount at least equal to the greater of (i) the amount of the aggregate dividends then accrued on such share of the Series C Preferred Stock and not previously paid and (ii) in the case of a dividend on the Common Stock or any class or series that is convertible into Common Stock, that dividend per share of Series C Preferred Stock as would

equal the product of (1) the dividend payable on each share of such class or series determined, if applicable, as if all shares of such class or series had been converted into Common Stock and (2) the number of shares of Common Stock issuable upon conversion of a share of the Series C Preferred Stock.

No dividends have been declared to date on any shares of Preferred Stock.

Liquidation

In the event of any liquidation, dissolution or winding up of the Company, either voluntarily or involuntarily, the holders of the Series C Preferred Stock are entitled to receive, prior and in preference to the holders of the Common Stock, a per share amount equal to the original issue price ($25.00 per share) plus any accrued but unpaid dividends thereon.

If upon the liquidation, dissolution or winding up of the Company, the assets of the Company that are legally available for distribution to the holders of the Series C Preferred Stock are insufficient to permit the payment to such holders of the full amounts above, then the entire assets of the Company that are legally available for distribution shall be distributed with equal priority and pro rata among the holders of the Series C Preferred Stock in proportion to what they would otherwise be entitled to receive.

After the payment of the full Series C Preferred Stock liquidation preference and unpaid accrued dividends, the holders of the Series C Preferred Stock shall participate in the distribution of the entire remaining assets of the Company legally available for distributions pro rata to holders of the Common Stock on an as converted basis. The sale of a majority of the capital stock of the Company or the sale, lease, transfer, exclusive license or other disposition, in a single transaction or series of related transactions, by the Company or any subsidiary of the Company of all or substantially all the assets of the Company and its subsidiaries taken as a whole shall be a “Deemed Liquidation Event” for the purpose of the Series C Preferred Stock.

Conversion

Each share of Series C Preferred Stock is convertible, at the option of the holder, at any time after the date of issuance of such share, into such number of fully paid and non-assessable shares of Common Stock determined by dividing the original issue price of $25.00 by the conversion price for such series in effect at the time of conversion for the Series C Preferred Stock. The conversion price for the Series C Preferred Stock is subject to adjustment in accordance with conversion provisions contained in our Certificate of Designations, Number, Voting Power, Preferences and Rights of Series C Convertible Preferred Stock dated March 12, 2019. As of February 28, 2024, the conversion price of the Series C Preferred Stock was $1.47 per share. See “— Antidilution Provisions” below.

Each share of Series C Preferred Stock automatically converts into shares of Common Stock at the conversion price at the time in effect immediately upon the Company’s sale of its Common Stock in a public offering provided that the offering price is not less than $16.50 per share (as adjusted for recapitalizations, stock combinations, stock dividends, stock splits and the like) and which results in aggregate cash proceeds of not less than $20.0 million before underwriting discounts, commissions, and fees. As of the date of this prospectus, no such sale has occurred.

Warrants

Investor Warrants

We issued the Investor Warrants in connection with various funding transactions or as consideration, in lieu of cash, for amounts billed in respect of services rendered to us. The Investor Warrants have terms ranging from five to ten years from the date of issuance. As of February 28, 2024, there were Investor Warrants to purchase 530,664 shares of Common Stock at exercise prices ranging from $0.17 to $8.25 per share.

Warrants issued in connection with the MSW Note

In September 2023, we issued warrants in lieu of a facility fee payment in connection with entering into the MSW Note with Matthews Southwest Holdings. These warrants have a five-year term from the date of issuance. As of February 28, 2024, there were 1,000,000 Existing MSW Warrants at an original exercise prices ranging from $1.00 to

$1.50 per share. On November 16, 2023, we entered into a Warrant Amendment Agreement with Matthews Southwest Holdings, amending the Existing MSW Warrants to reduce the exercise price of an aggregate of 1,000,000 Existing MSW Warrants to $0.16 per share.

Warrants issued in connection with the 2021 Bridge Financing

We issued the Bridge Warrants to originally purchase 775,420 shares of Common Stock in connection with the 2021 Bridge Financing. The Bridge Warrants expire five years after the date of issuance, beginning on December 22, 2026, with an initial exercise price of $9.08 per share, subject to certain adjustments. No holder of a Bridge Warrant may exercise any portion of a Bridge Warrant if after giving effect to such exercise, such holder (together with its Attribution Parties) would beneficially own in excess of 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of such holder’s Bridge Warrant. This limitation may be waived by a holder, at its election, upon not less than 61 days’ prior notice to the Company, to change the limitation to 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of such holder’s warrant. Any exercise of the Bridge Warrants resulting in a number of shares in excess of 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the exercise shall be deemed null and void and shall be cancelled ab initio.

On September 8, 2022, we entered into an amendment to the Bridge Warrants, which we refer to as the Bridge Warrant Amendment No. 1. The Bridge Warrant Amendment No. 1 amended the Bridge Warrants by (i) increasing the number of shares of Common Stock for which the Bridge Warrants are exercisable from a total of 1,365,960 shares to a total of 1,683,470 shares, (ii) lowering the exercise price to $4.25 per share, (iii) providing that, until June 15, 2023, the exercise price will be further adjusted whenever the Company issues shares of Common Stock for consideration per share that when multiplied by 1.25 is less than the exercise price then in effect, subject to certain exceptions, (iv) confirming that, for purposes of the Bridge Warrants, the value of each share of Common Stock and each IPO Warrant was deemed to be $4.125 and $0.125, respectively, (v) providing that the number of shares of Common Stock underlying the Bridge Warrants will only be adjusted if the Company (a) pays a stock dividend on one or more classes of its then outstanding shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (b) subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its then outstanding shares of Common Stock into a larger number of shares or (c) combines (by combination, reverse stock split or otherwise) one or more classes of its then outstanding shares of Common Stock into a smaller number of shares, and (vi) amending the formula for calculating Black Scholes values.

On February 3, 2023, we entered into a second amendment to the Bridge Warrants, which we refer to as the Bridge Warrant Amendment No. 2. The Bridge Warrant Amendment No. 2 amended the Bridge Warrants by (i) lowering the exercise price of $4.25 for the Limited Period, during which period the exercise price was set at $1.00, subject to adjustments set forth in the Bridge Warrant; (ii) providing that during the Limited Period, the holder was able, in its sole discretion, to elect a cashless exercise of the Bridge Warrant in whole or in part, pursuant to which the holder received a net number of shares of Common Stock equal to one-third of the total number of shares into which the Bridge Warrant could otherwise have been exercised; and (iii) removing the exercise price adjustment provisions of the Bridge Warrants with limited exceptions for transactions such as stock dividends, stock splits, stock combinations and reverse stock splits. Additionally, the Bridge Warrant Amendment No. 2 provided that in the event that the aggregate number of shares of Common Stock to be received by a holder upon an exercise of its Bridge Warrant during the Limited Period would result in such holder’s receiving shares of Common Stock in excess of its applicable Bridge Maximum Percentage, in lieu of delivery of shares of Common Stock in excess of the Bridge Maximum Percentage, the holder would receive such excess shares as pre-funded warrants substantially in the form of the Pre-Funded Bridge Warrants, with certain exercise price adjustment provisions removed. Further, the Bridge Warrant Amendment No. 2 included a waiver of Section 4(w) of the Bridge SPA, which placed certain restrictions on the Company’s ability to issue securities for a specified period of time.

During the Limited Period, Bridge Warrants were exercised for (i) a total of 1,172,304 shares of Common Stock at an exercise price of $1.00 per share or pursuant to cashless exercises in which the holder received a net number of shares of Common Stock equal to one-third of the total number of shares with respect to which the Bridge Warrant was exercised and (ii) the Remaining Pre-Funded Bridge Warrant to purchase 150,000 shares of Common Stock. At the end the Limited Period, Remaining Bridge Warrants to purchase a total of 298,667 shares of Common Stock remained outstanding, with the exercise price adjusted back to $4.25 per share, subject to future adjustments as set forth in the Remaining Bridge Warrants.

The exercise price of the Remaining Bridge Warrants (as amended by the Bridge Warrant Amendment No. 1 and the Bridge Warrant Amendment No. 2) is subject to adjustment for certain events such as stock dividends, splits, and reverse splits or other combinations, but not otherwise as the result of issuances of additional securities by the Company, even if such issuances are at prices below the exercise price of the Bridge Warrants. Upon an adjustment of the exercise price as a result of a stock dividend, split, reverse split, combination or similar event, the number of shares of Common Stock to be received shall be proportionately adjusted. Otherwise, there are no antidilution provisions that result in adjustments to the number of shares of Common Stock to be received upon exercise of the Bridge Warrants.

All Pre-Funded Bridge Warrants that were issued upon conversion of the Bridge Notes have been exercised in full and are no longer outstanding as of the date of this prospectus, although the Remaining Pre-Funded Bridge Warrant issued in connection with Bridge Warrant Amendment No. 2 remains outstanding. For more information regarding the Bridge Warrants, please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Description of Indebtedness — 2021 Bridge Financing”.

$1.5M Lender Warrants

In November 2021, we issued the $1.5M Lender Warrants exercisable for 4,545 shares of our Common Stock to noteholders of the $1.5M Notes as consideration for the extension of the maturity of the $1.5M Notes to January 31, 2023. The $1.5M Lender Warrants expire on October 12, 2026. The exercise price of the $1.5M Lender Warrants was $2.89 per share as of February 28, 2024.

$1M Lender Warrants

In November 2021, we issued warrants to purchase 15,152 shares of our Common Stock, which we refer to as the $1M Lender Warrants, to the lenders of the $1M Notes as consideration for the extension of the maturity of the $1M Loan and Security Agreement to September 30, 2022. The $1M Loan and Security Agreement was further amended in May 2022 to extend the maturity date to September 30, 2023 and amended again in January 2023 to (i) further extend the maturity date of the portion of the $1M Notes issued to one lender (in the principal amount of $0.5 million) to March 31, 2024 and (ii) further extend the maturity date of the remaining portion of the $1M Notes issued to the other lender (in the principal amount of $0.5 million) to September 30, 2024. The $1M Loan and Security Agreement was further amended in September 2023 to extend the interest maturity date to one lender to December 31, 2023. In October 2023, we issued additional $1M Lender Warrants to purchase 200,000 shares of our Common Stock to lenders of the $1M Notes as consideration for the extension of the interest maturity date to one lender. The exercise prices of the $1M Lender Warrants range from $0.16 to $2.89 per share as of February 28, 2024. On November 16, 2023, we entered into the Adams Warrant Amendment, amending the $1M Lender Warrants owned by Adams to reduce the exercise price of an aggregate of 107,575 $1M Lender Warrants to $0.16 per share.

IPO Warrants

The following summary of certain terms and provisions of the IPO Warrants that were included in the units (the “IPO Units”) that we offered and sold in our previously completed initial public offering of the IPO Units, plus the additional IPO Warrants issued as a result of the exercise, in part, of the underwriter’s over-allotment option in the IPO, is not complete and is subject to, and qualified in its entirety by, the provisions of the warrant agent agreement between us and Equiniti Trust Company, LLC, as warrant agent, and the form of warrant, both of which are included as exhibits to the registration statement of which this prospectus is a part.

Exercisability.    The IPO Warrants are exercisable at any time until 5:00 P.M. New York City time on June 17, 2027. The IPO Warrants are exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and, at any time a registration statement registering the issuance of the shares of Common Stock underlying the IPO Warrants under the Securities Act, is effective and available for the issuance of such shares of Common Stock, or an exemption from registration under the Securities Act is available for the issuance of such shares of Common Stock, by payment in full in immediately available funds for the number of shares of Common Stock purchased upon such exercise. If a registration statement registering the issuance of the Common Stock underlying the IPO Warrants under the Securities Act is not effective or available and an exemption from registration under the Securities Act is not available for the issuance of such Common Stock, the holder may, in its sole discretion, elect to exercise the IPO Warrant through a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of Common Stock determined according to the formula set forth in the IPO Warrant. No

fractional shares of Common Stock will be issued in connection with the exercise of an IPO Warrant. In lieu of fractional shares, we will pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price. We will not effect the exercise of any portion of the IPO Warrants, and the holder will not have the right to exercise any portion of the IPO Warrants, and any such exercise shall be null and void and treated as if never made, to the extent that after giving effect to such exercise, the holder together with its affiliates and certain other persons specified in the IPO Warrants collectively would own beneficially in excess of 4.99% (or, upon election by a holder prior to the issuance of any IPO Warrants, 9.99%) of the shares of Common Stock outstanding immediately after giving effect to such exercise.

Exercise Price.    The exercise price per share purchasable upon exercise of the IPO Warrants is $4.25 per share. The exercise price is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our shares of Common Stock and also upon any distributions of assets, including cash, stock or other property to our shareholders.

Transferability.    Subject to applicable laws, the IPO Warrants may be offered for sale, sold, transferred or assigned without our consent.

Warrant Agent.    The IPO Warrants were issued in registered form under a warrant agent agreement between Equiniti Trust Company, LLC, as warrant agent, and us. The IPO Warrants shall be represented only by one or more global warrants deposited with the warrant agent, as custodian on behalf of The Depository Trust Company (“DTC”) and registered in the name of Cede & Co., a nominee of DTC, or as otherwise directed by DTC.

Fundamental Transactions.    In the event of a fundamental transaction, as described in the IPO Warrants and generally including any reorganization, recapitalization or reclassification of our ordinary shares, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding shares of Common Stock, or any person or group becoming the beneficial owner of 50% of the voting power represented by our shares of Common Stock, the holders of the IPO Warrants will be entitled to receive upon exercise of the IPO Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the IPO Warrants immediately prior to such fundamental transaction.

Rights as a Shareholder.    Except as otherwise provided in the IPO Warrants or by virtue of such holder’s ownership of our shares of Common Stock, the holder of an IPO Warrant does not have the rights or privileges of a holder of our Common Stock, including any voting rights, until the holder exercises the IPO Warrant.

Governing Law.    The IPO Warrants and the warrant agent agreement are governed by New York law.

IPO Underwriter Warrants

At the consummation of the IPO, we issued warrants to the underwriter, or the IPO Underwriter Warrants, to purchase 105,000 shares of Common Stock, representing 7.0% of the aggregate number of shares of Common Stock underlying the IPO Units sold in the IPO. The IPO Underwriter Warrants expire at 5:00 P.M. New York City time on June 17, 2027, have an exercise price equal to $4.25, which is equal to 100% of the public offering price per IPO Unit in the IPO, provide for a “cashless” exercise, and contain certain antidilution adjustments (but excluding any price based antidilution). The IPO Underwriter Warrants contain provisions for unlimited “piggyback” registration rights for a period of no greater than three (3) years from the date of the IPO in compliance with FINRA Rule 5110(g)(8)(D). Pursuant to FINRA Rule 5110I, the IPO Underwriter Warrants and any shares of Common Stock issued upon exercise of the IPO Underwriter Warrants may not be sold, transferred, assigned, pledged, or hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of the securities by any person for a period of 180 days beginning on the date of commencement of sales of the IPO, except certain transfers of such securities, including: (i) by operation of law or by reason of our reorganization; (ii) to any FINRA member firm participating in the IPO and the officers or partners thereof, if all securities so transferred remain subject to lock-up restriction set forth in Section 4(a) of the IPO Underwriter Warrants for the remainder of the time period; (iii) if the aggregate amount of our securities held by the IPO underwriter or related persons do not exceed 1% of the securities offered in the IPO; (iv) that is beneficially owned on a pro rata basis by all equity owners of an investment fund, provided that no participating member manages or otherwise directs investments by the fund

and the participating members in the aggregate do not own more than 10% of the equity in the fund; or (v) the exercise or conversion of any security, if all securities remain subject to the lock-up restriction set forth in Section 4(a) of the IPO Underwriter Warrants for the remainder of the time period.

Options

We previously granted certain of our employees and board members stock option awards where vesting is contingent upon a service period, as we believe that such awards better align the interests of our employees with those of our shareholders. Such stock option awards were granted with an exercise price equal to or above the market price of our Common Stock at the date of grant. Certain stock option awards provide for accelerated vesting if there is a change in control, as defined in the option agreement. Stock options may not, subject to certain limited exceptions, be exercised when an employee leaves our Company. Where option awards were granted based on service periods, they generally vest quarterly based on three years of continuous service for executive directors and employees, or 12 months continuous service for directors and have 10-year contractual terms. As of February 28, 2024, there were time-based options to purchase a total of 1,218,367 shares of Common Stock at an average exercise price of $1.98 per share.

We also previously granted stock option awards where vesting is contingent upon meeting various departmental and/or company-wide performance goals, including, in some instances, FDA and/or CE Mark regulatory approval and/or certain EBITDA and funding thresholds. Such performance-based stock options are expected to vest when the performance criteria and metrics have been met. These stock options have a term of ten years. As of February 28, 2024, there were performance-based options to purchase a total of 566,540 shares of Common Stock at an average exercise price of $5.03 per share.

Antidilution Provisions

As of February 28, 2024, 6,483,709 shares of Common Stock issuable upon conversion of the Series C Preferred Stock were subject to antidilution protection provisions. The holders of these securities may be entitled to receive additional shares of Common Stock upon conversion of the Series C Preferred Stock.

Anti-takeover Effects of Certain Provisions of Our Certificate of Formation, Bylaws and Texas Law

Our Certificate of Formation and Bylaws and the TBOC contain provisions, which are summarized in the following paragraphs, which are intended to enhance the likelihood of continuity and stability in the composition of our Board of Directors. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile change of control and enhance the ability of our Board of Directors to maximize shareholder value in connection with any unsolicited offer to acquire us. However, these provisions may have an anti-takeover effect and may delay, deter or prevent a merger or acquisition of the Company by means of a tender offer, a proxy contest or other takeover attempt that a shareholder might consider in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of Common Stock held by shareholders.

Authorized but unissued capital stock

Texas law does not require shareholder approval for any issuance of authorized shares. However, the listing requirements of the Nasdaq, which apply so long as our securities are listed on the Nasdaq, require shareholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of Common Stock. Additional shares that may be issued in the future may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

Our Board of Directors may generally issue shares of Preferred Stock on terms calculated to discourage, delay or prevent a change of control of the Company or the removal of our management. Moreover, our authorized but unissued shares of Preferred Stock are available for future issuances without shareholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, to facilitate acquisitions and employee benefit plans.

One of the effects of the existence of unissued and unreserved shares of Common Stock or Preferred Stock may be to enable our Board of Directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of the Company by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of our management and possibly deprive our shareholders of opportunities to sell their shares of Common Stock at prices higher than prevailing market prices.

Classified Board of Directors

Our Certificate of Formation provides that our Board of Directors be divided into three classes of directors, with the classes to be as nearly equal in number as possible, and with the directors serving three-year terms. As a result, approximately one-third of our Board of Directors will be elected each year. The classification of directors will have the effect of making it more difficult for shareholders to change the composition of our Board of Directors. Our Certificate of Formation and Bylaws provide that, subject to any rights of holders of Preferred Stock to elect additional directors under specified circumstances, the number of directors will be fixed from time to time exclusively pursuant to a resolution adopted by the Board of Directors.

Removal of directors; vacancies

Under the TBOC, unless otherwise provided in our Certificate of Formation, directors serving on a classified board may be removed by the shareholders only for cause. Our Certificate of Formation provides that directors may be removed only for cause. In addition, our Certificate of Formation also provides that, subject to the rights granted to one or more series of Preferred Stock then outstanding, any vacancy occurring in our Board of Directors may be filled by election at an annual or special meeting of the shareholders called for that purpose or by the affirmative vote of a majority of the directors then in office (even if the remaining directors constitute less than a quorum of the Board of Directors), and any director so chosen shall hold office for the remainder of the term to which the director has been selected and until such director’s successor shall have been elected and qualified.

No cumulative voting

Under Texas law, the right to vote cumulatively does not exist unless the certificate of formation specifically authorizes cumulative voting. Our Certificate of Formation does not authorize cumulative voting. Therefore, shareholders holding a majority in voting power of the shares of our stock entitled to vote generally in the election of directors will be able to elect all our directors.

Special shareholder meetings

Our Certificate of Formation provides that special meetings of our shareholders may be called at any time by the Board of Directors, the chairman of the Board of Directors or the chief executive officer of the Company. Our Bylaws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of the Company.

Requirements for advance notification of director nominations and shareholder proposals

Our Bylaws establish advance notice procedures with respect to shareholder proposals and the nomination of for election as directors, other than nominations made by or at the direction of the Board of Directors or a committee of the Board of Directors. In order for any matter to be “properly brought” before a meeting, a shareholder will have to comply with advance notice requirements and provide us with certain information. Generally, to be timely, a shareholder’s notice must be received at our principal executive offices not less than 75 days nor more than 100 days prior to the first anniversary date of the immediately preceding annual meeting of shareholders. Our Bylaws also specify requirements as to the form and content of a shareholder’s notice. Our Bylaws allow the chairman of the meeting at a meeting of the shareholders to adopt rules and regulations for the conduct of meetings which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed. These provisions may also defer, delay or discourage a potential acquiror from conducting a solicitation of proxies to elect the acquiror’s own slate of directors or otherwise attempting to influence or obtain control of the Company.

Shareholder action by written consent

Our Certificate of Formation provides that any action required or permitted to be taken at an annual or special meeting of shareholders may be taken by written consent in lieu of a meeting of shareholders only with the unanimous written consent of our shareholders.

Amendment and restatement of bylaws

Our Bylaws provide that the Board of Directors is expressly authorized to make, alter, amend, change, add to, rescind or repeal, in whole or in part, our Bylaws without a shareholder vote in any matter not inconsistent with the laws of the State of Texas and our Certificate of Formation.

The combination of the classification of our Board of Directors and the lack of cumulative voting will make it more difficult for shareholders to replace our Board of Directors as well as for another party to obtain control of us by replacing our Board of Directors. Because our Board of Directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing shareholders or another party to effect a change in management.

These provisions may have the effect of deterring hostile takeovers or delaying or preventing changes in control of our management or the Company, such as a merger, reorganization or tender offer. These provisions are intended to enhance the likelihood of continued stability in the composition of our Board of Directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of the Company. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions are also intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions may also have the effect of preventing changes in management.

Dissenters’ rights of appraisal and payment

Under the TBOC, with certain exceptions, our shareholders will have appraisal rights in connection with a merger, a sale of all or substantially all of our assets, an interest exchange or a conversion. Pursuant to the TBOC, shareholders who properly request and perfect appraisal rights in connection with such merger, sale of all or substantially all of our assets, interest exchange or conversion will have the right to receive payment of the fair value of their shares as agreed to between the shareholder and the Company or, if they are unable to reach agreement, as determined by the State District Court in Tarrant County, Texas.

Shareholders’ derivative actions

Under the TBOC, any of our shareholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the shareholder bringing the action (i) is a holder of our shares at the time of the transaction to which the action relates or such shareholder became a shareholder by operation of law from a person that was a shareholder at the time of the transaction to which the action relates and (ii) fairly and adequately represents the interests of the Company in enforcing the right of the Company.

Limitations on liability and indemnification of officers and directors

The TBOC authorizes corporations to limit or eliminate the personal liability of directors to corporations and their shareholders for monetary damages for breaches of directors’ fiduciary duties (other than breaches of the directors’ duty of loyalty to corporations or their shareholders), subject to certain exceptions. Our Certificate of Formation includes a provision that limits the personal liability of directors for monetary damages for an act or omission in the director’s capacity as a director to the fullest extent permitted by Texas law. However, exculpation will not apply to any director if the director has acted in bad faith, engaged in intentional misconduct, knowingly violated the law, authorized illegal dividends or redemptions, derived an improper benefit from his or her actions as a director or engaged in an act or omission for which the liability of the director is expressly provided by an applicable statute.

Our Certificate of Formation provides that we must indemnify our directors and officers to the fullest extent authorized by the TBOC. We also are expressly authorized to carry directors’ and officers’ liability insurance providing indemnification for our directors, officers and certain employees for some liabilities. We believe that these indemnification provisions and insurance will be useful to attract and retain qualified directors and officers.

The limitation of liability and indemnification provisions in our Certificate of Formation and Bylaws may discourage shareholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though

DISCLOSURE OF COMMISSION POSITION ON
INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 13.     Other Expenses of Issuance and Distribution.

The following table sets forth the expenses to be incurred in connection with the offering described in this registration statement, all of which will be paid by the registrant. All amounts are estimates except the SEC registration fee.

Item 14.     Indemnification of Directors and Officers

Heart Test Laboratories, Inc. (the “Company”, “we”, “us” or “our”) was incorporated under the laws of Texas.

The Texas Business Organizations Code (the “TBOC”) permits a corporation to indemnify a director who was, is or is threatened to be a named defendant or respondent in a proceeding as a result of the performance of his duties if such person acted in good faith and, in the case of conduct in the person’s official capacity as a director, in a manner he reasonably believed to be in the best interests of the corporation and, in all other cases, that the person reasonably believed his conduct was not opposed to the best interests of the corporation and with respect to any criminal action or proceeding, that such person had no reasonable cause to believe his conduct was unlawful.

Subject to certain exceptions, the TBOC further permits a corporation to eliminate in its certificate of formation all monetary liability of the corporation’s directors to the corporation or its shareholders for conduct in performance of such director’s duties. Our amended and restated certificate of formation (the “Certificate of Formation”) provides that a director of the Company will not be liable to the Company or its shareholders for monetary damages for any act or omission by the director in the performance of his duties, except that, pursuant to the TBOC, there will be no limitation of liability to the extent the director has been found liable under applicable law for: (i) breach of the director’s duty of loyalty owed to our Company or our shareholders; (ii) an act or omission not in good faith that constitutes a breach of duty of the director to our Company or that involves intentional misconduct or a knowing violation of the law; (iii) a transaction from which the director received an improper benefit, regardless of whether the benefit resulted from an action taken within the scope of the director’s duties; or (iv) an act or omission for which the liability of the director is expressly provided for by an applicable statute.

Sections 8.101 and 8.103 of the TBOC provide that a corporation may indemnify a person who was, is or is threatened to be a named defendant or respondent in a proceeding because the person is or was a director only if a determination is made that such indemnification is permissible under the TBOC: (i) by a majority vote of the directors who at the time of the vote are disinterested and independent, regardless of whether such directors constitute a quorum; (ii) by a majority vote of a board committee designated by a majority of disinterested and independent directors and consisting solely of disinterested and independent directors; (iii) by special legal counsel selected by the board of directors or a committee of the board of directors as set forth in (i) or (ii); (iv) by the shareholders in a vote that excludes the shares held by directors who are not disinterested and independent; or (v) by a unanimous vote of the shareholders.

Section 8.104 of the TBOC provides that a corporation may pay or reimburse, in advance of the final disposition of the proceeding, reasonable expenses incurred by a present director who was, is or is threatened to be made a named defendant or respondent in a proceeding after the corporation receives a written affirmation by the director of his good faith belief that he has met the standard of conduct necessary for indemnification under Section 8.101 and a written undertaking by or on behalf of the director to repay the amount paid or reimbursed if it is ultimately determined that he has not met that standard or if it is ultimately determined that indemnification of the director is not otherwise permitted under the TBOC. Section 8.105 also provides that reasonable expenses incurred by a former director, or a present or

former employee, agent or officer of a corporation, who was, is or is threatened to be made a named defendant or respondent in a proceeding may be paid or reimbursed by the corporation, in advance of the final disposition of the action, as the corporation considers appropriate.

Section 8.105 of the TBOC provides that, subject to restrictions in its certificate of formation and to the extent consistent with other law, a corporation may indemnify and advance expenses to a person who is not a director, including an officer, employee or agent of the corporation as provided by: (i) the corporation’s governing documents; (ii) an action by the corporation’s governing authority; (iii) resolution by the shareholders; (iv) contract; or (v) common law. As consistent with Section 8.105, persons who are not directors may seek indemnification and advancement of expenses from the Company to the same extent that directors may seek indemnification and advancement of expenses from the Company.

Further, our Certificate of Formation and second amended and restated bylaws (the “Bylaws”) provide that we must indemnify our directors and officers to the fullest extent authorized by law. We believe that these indemnification provisions and the directors’ and officers’ insurance are useful to attract and retain qualified directors and executive officers.

We have also entered into indemnification agreements with each of our directors and certain of our officers. The indemnification agreements provide, among other things, for indemnification to the fullest extent permitted by the TBOC and our Certificate of Formation and Bylaws against (i) any and all direct and indirect liabilities and reasonable expenses, including judgments, fines, penalties, interest and amounts paid in settlement of any claim with our approval and reasonable counsel fees and disbursements and (ii) any liabilities incurred as a result of serving as a director, officer, employee or agent (including as a trustee, fiduciary, partner or manager or in a similar capacity) of another enterprise or an employee benefit plan at our request. The indemnification agreements also provide for, or will provide for, the advancement or payment of expenses to the indemnitee and for reimbursement to us if it is found that such indemnitee is not entitled to such indemnification under applicable law and our Certificate of Formation and Bylaws or the terms of the indemnification agreements.

We expect to maintain standard policies of insurance that provide coverage (1) to our directors and officers against loss rising from claims made by reason of breach of duty or other wrongful act and (2) to us with respect to indemnification payments that we may make to such directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”), may be permitted to directors, officers or persons controlling us under any of the foregoing provisions, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 15.     Recent Sales of Unregistered Securities

In the three years preceding the filing of this registration statement, we have issued the securities described in this section, which were not registered under the Securities Act.

•        From December 2020 to April 2021, we issued and sold secured convertible promissory notes (the “$1.5M Notes”) to accredited investors in the aggregate principal amount of $1.5 million. The $1.5M Notes accrue interest at a rate of 12% per annum.

•        In June 2021, July 2021, and November 2021, we issued warrants to purchase 30,781 shares of our Common Stock, par value $0.001 per share (the “Common Stock”), in exchange for consulting services and extensions of the $1M Loan and Security Agreement and the $1.5M Notes. See “Description of Securities-$1M Lender Warrants and $1.5M Lender Warrants” for a description of these warrants.

•        In August 2021, the Company issued 10,101 shares of Common Stock as a facility fee in connection with the Unsecured Promissory Draw Down Note for non-cash consideration amounting to $35,000.

•        From October 2021 to February 28, 2022, we issued and sold senior subordinated convertible notes (the “Bridge Notes”) in the aggregate principal amount of $4.7 million to accredited investors for net proceeds of $4.2 million after deduction of the 10% original issue discount on our Bridge Notes (the “2021 Bridge Financing”). The Bridge Notes accrued interest at a rate of 8% per annum. The Company received net proceeds of approximately $4.2 million.

•        In connection with the 2021 Bridge Financing, the Company issued Bridge Warrants to purchase 1,365,960 shares of Common Stock (as adjusted following consummation of the IPO, as required under the terms of the Bridge Warrants). The Bridge Warrants have a 5-year term from their date of issuance and, in accordance with their terms following the IPO, had the right to purchase 1,365,960 shares of Common Stock at an exercise price of $5.16 per share. The exercise price of the Bridge Warrants was subject to full ratchet downward adjustment for 18-months following the IPO in the event of an issuance of Common Stock (or issuance of convertible securities or options at a lower price conversion/exercise price) than the then exercise price. Upon a lowering of the exercise price the holder was entitled to exercise the Bridge Warrants, so the new exercise price multiplied by the number of shares of Common Stock purchased was 150% of the principal amount of the 2021 Bridge Notes purchased. Upon consummation of the IPO, and as required under the terms of the Bridge Notes, the Company issued 1,606,026 shares of Common Stock and pre-funded warrants to purchase 77,443 shares of Common Stock from the conversion of the Bridge Notes.

•        In June 2022, as a result of the IPO, as required under the terms of the $1.5M Notes, the Company issued 909,071 shares of Common Stock from the conversion of the $1.5M Notes.

•        In June 2022, as a result of the IPO, the Series B convertible preferred stock, par value $0.001 per share, was cancelled and we issued 703,290 shares of Common Stock to certain officers, prior directors and employees in connection with the conversion of the Series A convertible preferred stock, par value $0.001 per share.

•        In July 2022, August 2022, October 2022, February 2023, and July 2023 we issued an aggregate of 359,792 shares of Common Stock without the payment of additional consideration upon the conversion of 88,025 shares of our Series C convertible preferred stock, par value $0.001 per share (the “Series C Preferred Stock”), by a holder. Such shares of Common Stock were issued in reliance on the exemption from registration provided by Section 4(a)(2) and/or Section 3(a)(9) of the Securities Act. In accordance with Section 3(a)(9) of the Securities Act, the securities were exchanged by the Company with its existing security holder in a transaction where no commission or other remuneration was paid or given directly or indirectly for soliciting such exchange.

•        In September 2022, we issued warrants (the “Pre-Funded Bridge Warrants”) to purchase 61,913 shares of Common Stock to an accredited investor in connection with the cancellation of 61,913 shares of Common Stock (with the issuance of such cancelled shares being deemed null and void, ab initio) pursuant to provisions in the Bridge Notes limiting the number of shares of Common Stock into which the Bridge Notes were convertible.

•        In September 2022, as a result of the Amendment No. 1 to Bridge Warrant by and between Heart Test Laboratories, Inc. and the lead investor under the Bridge SPA, dated September 8, 2022 (the “Bridge Warrant Amendment No. 1”), the number of shares of Common Stock for which the Bridge Warrants are exercisable increased by 317,510 shares. The Bridge Warrant Amendment No. 1, including the issuance of the shares of Common Stock underlying the Bridge Warrants and of the amended and restated Bridge Warrants to accredited investors, was completed in accordance with Section 3(a)(9) of the Securities Act, as securities exchanged by the Company with its existing security holders in a transaction where no commission or other remuneration was paid or given directly or indirectly for soliciting such exchange, and/or Section 4(a)(2) of the Securities Act, as a transaction by an issuer not involving any public offering.

•        In January 2023, the lead investor, under the Securities Purchase Agreement we entered into with the Bridge Purchasers in connection with the 2021 Bridge Financing (the “Bridge SPA”), exercised its Pre-Funded Bridge Warrants in full to acquire 139,356 shares of Common Stock at an exercise price of $0.0001 per share, for a total exercise price of $13.94.

•        In February 2023, we entered into Amendment No. 2 to Bridge Warrant by and between the Company and the lead investor under the Bridge SPA, dated February 3, 2023 (the “Bridge Warrant Amendment No. 2”), which included the issuance of the shares of Common Stock underlying the Bridge Warrants and the amended and restated Bridge Warrants to accredited investors, was completed in accordance with Section 3(a)(9) of the Securities Act, as securities exchanged by the Company with its existing security holders in a transaction where no commission or other remuneration was paid or given directly or indirectly for soliciting such

exchange, and/or Section 4(a)(2) of the Securities Act, as a transaction by an issuer not involving any public offering. During a period of ten business days beginning February 3, 2023 and ending February 16, 2023, the Company issued 1,172,304 shares of Common Stock and a pre-funded warrant to purchase 150,000 shares of Common Stock (the “Remaining Pre-Funded Bridge Warrant”) pursuant to exercises of the Bridge Warrants. The issuance of the shares of Common Stock upon the exercises of the Bridge Warrants were completed in accordance with Section 4(a)(2) of the Securities Act, as a transaction by an issuer not involving any public offering. The issuance of the Remaining Pre-Funded Bridge Warrant was completed in accordance with Section 3(a)(9) of the Securities Act. In accordance with Section 3(a)(9) of the Securities Act, the Remaining Pre-Funded Bridge Warrant was issued by the Company to its existing security holder in exchange for existing Bridge Warrants in a transaction where no commission or other remuneration was paid or given directly or indirectly for soliciting such exchange. The Remaining Pre-Funded Bridge Warrant will take on the registered characteristics of the existing Bridge Warrants as in effect prior to the Bridge Warrant Amendment No. 2.

•        In March 2023, we issued warrants to purchase an aggregate amount of 250,000 shares of our Common Stock at an exercise price of $1.04 per share as consideration, in lieu of cash, for approximately $203,000 billed in respect of research and development services rendered by a third-party to the Company.

Unless otherwise stated, the sales of securities described above were deemed to be exempt from registration pursuant to Section 4(a)(2) of the Securities Act, including Rule 506(b) of Regulation D promulgated thereunder, as transactions by an issuer not involving a public offering. All of the purchasers in these transactions represented to us in connection with their purchase that they were acquiring the securities for investment and not distribution, that they could bear the risks of the investment and could hold the securities for an indefinite period of time.

All of the foregoing securities are deemed restricted securities for the purposes of the Securities Act.

All financial statement schedules are omitted because the information called for is not required or is shown either in the financial statements or in the notes thereto.

Item 17.     Undertakings

(a)     The undersigned registrant hereby undertakes:

(1)    To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

i.       To include any prospectus required by Section 10(a)(3) of the Securities Act;

ii.      To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission (the “SEC”) pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

iii.     To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are incorporated by reference in this registration statement or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement.

(2)    That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)    To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)    That, for the purpose of determining liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(b)    The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial

information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus is to provide such interim financial information.

(c)     Insofar as indemnification for liabilities arising under the Securities Act, may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
