Up to 15,404,193 Shares of Common Stock Underlying the Series A Warrants, Series B Warrants and Series C Warrants

Each PFW Unit Consisting of One Pre-Funded Warrant to Purchase One Share of Common Stock

Up to 23,578,720 Shares of Common Stock Underlying the Pre-Funded Warrants, Series A Warrants, Series B Warrants and Series C Warrants

We are offering 5,134,731 common stock units (the “Common Stock Units”), each consisting of: (i) one share of our common stock, (ii) a Series A warrant to purchase one share of our common stock (the “Series A Warrant”), (iii) a Series B warrant to purchase one share of our common stock (the “Series B Warrant”), and (iv) a Series C warrant to purchase one share of our common stock (the “Series C Warrant,” and together with the Series A Warrant and Series B Warrant, the “Common Warrants”). The purchase price for each Common Stock Unit is $0.68. The Series A Warrants, Series B Warrants, and Series C Warrants have an exercise price per share equal to $0.68, which is equal to 100% of the price per Common Stock Unit sold in the offering. The Series A Warrants and Series B Warrants are exercisable immediately, subject to certain limitations described herein. The Series C Warrants may only be exercised to the extent and in proportion to a holder of the Series C Warrants exercising its corresponding Series B Warrants. The Series A Warrants will expire five years from the closing date of this offering. The Series B Warrants will expire nine months from the closing date of this offering. The Series C Warrants will also expire nine months from the closing date of this offering, provided that to the extent and in proportion to a holder of the Series C Warrants exercising its corresponding Series B Warrants included in the Common Stock Unit, such Series C Warrant will expire five years from the closing date of this offering. We are also offering the shares of our common stock that are issuable from time to time upon exercise of the Common Warrants.

We are also offering to each purchaser whose purchase of Common Stock Units in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if the purchaser so chooses, 5,894,680 pre-funded warrant units (the “PFW Units” and together with the Common Stock Units, the “Units”), in lieu of Common Stock Units that would otherwise result in the purchaser’s beneficial ownership exceeding 4.99% of our outstanding common stock. Each PFW Unit consists of: (i): pre-funded warrants to purchase one share of our common stock (the “Pre-Funded Warrants”), (ii) a Series A Warrant to purchase one share of our common stock, (iii) a Series B Warrant to purchase one share of our common stock, and (iv) a Series C Warrant to purchase one share of our common stock. The Common Warrants included in the PFW Units are identical to the Common Warrants included in the Common Stock Units. Subject to limited exceptions, a holder of Pre-Funded Warrants will not have the right to exercise any portion of its Pre-Funded Warrants if the holder, together with its affiliates, would beneficially own in excess of 4.99% (or, at the election of the holder, 9.99%, 14.99%, or 19.99%) of the number of shares of common stock outstanding immediately after giving effect to such exercise. Each Pre-Funded Warrant will be exercisable for one share of common stock at an exercise price of $0.0001 per share of common stock. The public offering price per PFW Unit is equal to the public offering price per Common Stock Unit less $0.0001. Each Pre-Funded Warrant will be exercisable upon issuance and will expire when exercised in full. We are also offering the shares of our common stock that are issuable from time to time upon exercise of the Pre-Funded Warrants.

The aggregate number of shares underlying each series of warrants is equal to 11,029,411 shares of Common Stock for a total of 33,088,233 shares underlying the Series A Warrants, Series B Warrants and Series C Warrants. The shares of common stock in the Common Stock Units or the Pre-Funded Warrants in the PFW Units, as applicable, and the accompanying Common Warrants, can only be purchased together in this offering but will be issued separately and will be immediately separable upon issuance; provided that a Series C Warrant may not be separated from the corresponding Series B Warrant until such Series B Warrant has been exercised.

Neither the Common Stock Units nor the PFW Units will be issued or certificated. The Common Stock Units, the PFW Units, the shares of common stock, the Common Warrants, the Pre-Funded Warrants and shares of common stock underlying the Common Warrants and Pre-Funded Warrants are sometimes collectively referred to herein as the “securities.”

Our common stock is listed on The Nasdaq Capital Market under the symbol “EVOK”. There is no established public trading market for the Pre-Funded Warrants or the Common Warrants, and we do not expect a market to develop. We do not intend to apply for listing of the Pre-Funded Warrants or the Common Warrants on any securities exchange or nationally recognized trading system. Without an active trading market, the liquidity of the Pre-Funded Warrants and the Common Warrants will be limited.

Overview

We are a specialty pharmaceutical company focused primarily on the development and commercialization of drugs to treat gastrointestinal (“GI”) disorders and diseases. Since our inception, we have devoted our efforts to developing our sole product, Gimoti® (metoclopramide) nasal spray, the first and only nasally-administered product indicated for the relief of symptoms in adults with acute and recurrent diabetic gastroparesis. In June 2020, we received approval from the U.S. Food and Drug Administration (“FDA”) for our 505(b)(2) New Drug Application for Gimoti (the “Gimoti NDA”). We launched commercial sales of Gimoti in the United States in October 2020 through our commercial partner, Eversana Life Science Services, LLC (“Eversana”).

Diabetic gastroparesis is a GI disorder affecting millions of patients worldwide, in which food in an individual’s stomach takes too long to empty resulting in a variety of serious GI symptoms and systemic metabolic complications. The gastric delay caused by gastroparesis can also compromise absorption of orally administered medications. In May 2023, we reported results from a study conducted by Eversana which showed diabetic gastroparesis patients taking Gimoti had significantly fewer physician office visits, emergency department visits, and inpatient hospitalizations compared to patients taking oral metoclopramide. This overall lower health resource utilization reduced patient and payor costs by approximately $15,000 during a six-month time period for patients taking Gimoti compared to patients taking oral metoclopramide.

Gastroparesis frequently occurs in individuals with diabetes, but is also observed in patients with prior gastric surgery, a preceding infectious illness, pseudo-obstruction, collagen vascular disorders and anorexia nervosa. In some patients with gastroparesis, no cause can be identified, which is referred to as idiopathic gastroparesis. According to the American Motility Society Task Force on Gastroparesis, the prevalence of gastroparesis is estimated to be up to 4% of the United States population. Signs and symptoms of gastroparesis may include nausea, early satiety, bloating, prolonged fullness, upper abdominal pain, vomiting and retching. Patients may experience any combination of signs and symptoms with varying frequency and degrees of severity.

In addition, we believe the increased use of GLP-1 (glucagon-like peptide-1) agonists could increase the number of people suffering from gastroparesis. GLP-1 receptor agonists affect glucose control through several mechanisms, including enhancement of glucose-dependent insulin secretion, slowed gastric emptying, and reduction of postprandial glucagon and food intake. Slow gastric emptying may potentially lead to symptoms similar to gastroparesis. Although definitive evidence attributing GLP-1 agonists specifically to causing gastroparesis is limited, a recent study published in the Journal of the American Medical Association found that use of GLP-1 agonists for weight loss compared with use of bupropion-naltrexone was associated with increased risk of pancreatitis, bowel obstruction and gastroparesis. While these adverse events from GLP-1 agonists are rare, we believe it could have an impact on the gastroparesis market, considering the increased use, the large population expected to be treated and the incidence rate.

Patients with diabetic gastroparesis may experience impaired glucose control due to unpredictable gastric emptying and altered absorption of orally administered drugs, which may affect the severity of their signs and symptoms. Any combination of issues or signs and symptoms may cause complications such as malnutrition, esophagitis, and Mallory‑Weiss tears. Gastroparesis adversely affects the lives of patients with the disease, resulting in decreased social interaction, poor work functionality, and the development of anxiety and/or depression.

We believe nasal spray administration has the potential to provide our target population of diabetic gastroparesis patients with a preferred treatment option over the tablet formulation for several important reasons: (1) unlike

metoclopramide tablets which may be absorbed erratically due to gastroparesis itself, Gimoti is designed to bypass the digestive system to allow for more predictable absorption without needing to determine if a patient’s stomach is functioning; (2) during episodes of vomiting, Gimoti may provide predictable drug absorption through the nasal mucosa; and (3) for gastroparesis patients experiencing nausea and are not wanting to swallow a pill or water, a nasal spray may be better tolerated than an oral medication.

In January 2020, we entered into a commercial services agreement with Eversana (as amended to date, the “Eversana Agreement”) for the commercialization of Gimoti. Pursuant to the Eversana Agreement, Eversana commercializes and distributes Gimoti in the United States. Eversana also manages the marketing of Gimoti to targeted health care providers, as well as the sales and distribution of Gimoti in the United States. In 2020, we borrowed $5 million from Eversana pursuant to a revolving credit facility (the “Eversana Credit Facility”) which expires on December 31, 2026, unless terminated earlier pursuant to its terms. The maturity date of all amounts, including interest, borrowed under the Eversana Credit Facility will be 90 days after the expiration or earlier termination of the Eversana Agreement. As of September 30, 2023, there were approximately $60.4 million in cumulative unreimbursed commercialization costs under the agreement (“Cumulative Deferred Costs”), to be payable only as net product profits are recognized, or upon certain termination events as described below. The Eversana Agreement terminates on December 31, 2026, unless terminated earlier pursuant to its terms. Among other reasons, either party has the right to terminate the Eversana Agreement upon 30 days prior written notice if the net profit under the agreement is negative for any two consecutive calendar quarters (the “Net Profit Quarterly Termination Right”). As of September 30, 2023, either party had the right to exercise the Net Profit Quarterly Termination Right, which either party could have done until November 29, 2023, which was the end of the 60-day period following the end of the quarter. Each party will continue to have the option to exercise this termination right for the 60-day period following the end of future quarters so long as the net profit under the agreement remains negative for consecutive quarters. Either party may also terminate the Eversana Agreement upon a change of control of our ownership. In the event that we initiate such termination, we shall pay to Eversana a one-time payment equal to all of Eversana’s unreimbursed costs (including the Cumulative Deferred Costs) plus a portion of Eversana’s commercialization costs incurred in the 12 months prior to termination. If Eversana initiates such termination following a change of control, none of the Cumulative Deferred Costs incurred by Eversana will be due from Evoke. If Eversana terminates the agreement due to an uncured material breach by us or if we terminate the Eversana Agreement in certain circumstances, including if we exercise the Net Profit Quarterly Termination Right, we have agreed to reimburse Eversana for its unreimbursed commercialization costs for the prior twelve-month period and certain other costs. Upon expiration of the agreement, none of the Cumulative Deferred Costs incurred by Eversana will be due from Evoke. Upon expiration or termination of the agreement, we will retain all profits from product sales and assume all corresponding commercialization responsibilities.

To date, we have only generated modest sales of Gimoti. We have incurred losses every year since our inception. These operating losses resulted from expenses incurred in connection with advancing Gimoti through development activities, from pre-commercialization and commercialization costs and from other general and administrative costs associated with operating our business. We expect to continue to incur operating losses until revenues from the sales of Gimoti exceed our expenses, if ever. We may never become profitable, or if we do, we may not be able to sustain profitability on a recurring basis.

Our Strategy

Our objective is to develop and bring to market products to treat acute and chronic GI disorders that are not satisfactorily treated with current therapies and represent significant market opportunities. Our business strategy is to:

•

Successfully commercialize Gimoti in the United States. Through our commercialization agreement with Eversana, we have built a commercial infrastructure to allow us to directly market Gimoti in the United States. We have engaged Eversana to utilize its internal sales organization, along with other commercial functions, for market access, marketing, distribution, and other related patient support services. If Eversana terminates the agreement, our plan moving forward to commercialize Gimoti is to initially employ a primarily digital marketing strategy. In addition, we may hire a select number of direct sales representatives to commercialize Gimoti.

•

Further development of Gimoti with a lower dosage strength to expand our market potential. We are evaluating the design of a single dose pharmacokinetics (“PK”) clinical trial of Gimoti, based on an FDA post-marketing commitment. This trial will be designed to characterize dose proportionality of a lower dosage

strength of Gimoti to accommodate patients that may require further dosage adjustments, with initiation timing pending additional feedback from the FDA.

•

Seek partnerships to accelerate and maximize the potential for Gimoti. We continue to evaluate partnering opportunities with pharmaceutical companies that have established development and sales and marketing capabilities to potentially enhance and accelerate the development and commercialization of Gimoti, including the potential to explore regulatory approval outside the United States.

•

In-license or acquire additional clinical or commercial stage product candidates for the treatment of GI diseases. We may opportunistically in-license or acquire additional programs targeting GI diseases, leveraging our prior development experience.

Financial Update

Our financial statements for the quarter and year ended December 31, 2023, will not be available until after this offering is completed and consequently will not be available to you prior to investing in our securities offered in this offering. Based upon preliminary estimates and information available to us as of the date of this registration statement, we expect to report that we had approximately $4.7 million of cash and cash equivalents as of December 31, 2023. We have not yet completed our quarter-end financial close process for the quarter ended December 31, 2023. This estimate of our cash and cash equivalents as of December 31, 2023 is preliminary, has not been audited and is subject to change upon completion of our financial statement closing procedures. Additional information and disclosure would be required for a more complete understanding of our financial position and results of operations as of December 31, 2023. Our independent registered public accounting firm has not audited, reviewed or performed any procedures with respect to this preliminary result and, accordingly, does not express an opinion or any other form of assurance about it.

Intellectual Property and Proprietary Rights

Overview

We are building an intellectual property portfolio for Gimoti in the United States and abroad. We seek patent protection in the United States and internationally for our product candidate, its methods of use and manufacture, and for other technologies, where appropriate. Our policy is to actively seek to protect our proprietary position by, among other things, filing patent applications in the United States and abroad relating to proprietary technologies that are important to the development of our business. We also rely on trade secrets, know-how, continuing technological innovation and in-licensing opportunities to develop and maintain our proprietary position. We cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future will be commercially useful in protecting our technology.

Our business success will depend significantly on our ability to:

•

secure, maintain and enforce patent and other proprietary protection for our core technologies, inventions and know-how;

•

obtain and maintain licenses to key third-party intellectual property owned by such third parties;

•

preserve the confidentiality of our trade secrets; and

•

operate without infringing upon valid, enforceable third-party patents and other rights.

Patent Portfolio

Our patent portfolio consists of patents and patent applications, including the following U.S. patents and patent applications as of December 31, 2023:

•

U.S. Patents 8,334,281; 11,020,361, 11,628,150, and 11,813,231 - Nasal Formulations of Metoclopramide. These patents are expected to expire no earlier than 2030, 2029, 2029, and 2029,

respectively, and claim common priority with two pending US continuation applications (17/366,818 and 17/366,839), each of which, if granted, would be expected to expire no earlier than 2029.

•

U.S. Non-Provisional Patent Application No. 17/381,464 – Treatment of Symptoms Associated with Female Gastroparesis. If granted, this patent is not expected to expire earlier than 2032.

•

U.S. Patent 11,517,545 – Treatment of Moderate and Severe Gastroparesis. This patent is expected to expire no earlier than 2038 and claims common priority with pending US continuation application 18/047,364 which, if granted, would be expected to expire no earlier than 2037 (U.S. Non-Provisional Patent Application No. 18/047,364).

We have also been granted European and Canadian patents for pharmaceutical compositions comprising metoclopramide. These patents are expected to expire no earlier than 2029. We have also been granted European, Japanese, Russian and Mexican patents for the use of intranasal metoclopramide for treating diabetic gastroparesis in human females. These patents are expected to expire no earlier than 2032. Two additional PTC patent applications have been filed related to more recent clinical trial findings.

Patents have a limited lifespan. In the United States, if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is limited. Even if patents covering our product candidate are obtained, once the patent life has expired, we may be open to competition from competitive products, including generics. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Risks Affecting Our Business

Our business is subject to a number of risks, including risks that may prevent us from achieving our business objectives or may adversely affect our business, financial condition, results of operations, cash flows and prospects that you should consider before making a decision to invest in our securities. These risks are discussed more fully in the section titled “Risk Factors” beginning on page 10 of this prospectus, and include the following:

•

Our business is entirely dependent on the success of Gimoti, which may never generate sufficient sales to become profitable.

•

Even if this offering is successful, we will require substantial additional funding and may be unable to raise capital when needed, which would force us to liquidate, dissolve or otherwise wind down our operations.

•

We have no internal sales, marketing or distribution capabilities currently and rely on Eversana, and may rely on other third parties, for the commercialization of Gimoti, and we and they may not be able to effectively market, sell and distribute Gimoti. If the Eversana Agreement is terminated, we would need to secure one or more third party service provider(s), or invest significant amounts of financial and management resources to develop our own capabilities, to commercialize Gimoti.

•

Any termination or suspension of, or delays in the completion of, the post-marketing PK trial of Gimoti or any other future clinical trials could result in increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.

•

We and Eversana will need to retain qualified sales and marketing personnel and collaborate in order to successfully commercialize Gimoti.

•

Use of Gimoti or any future product candidates we may develop could be associated with side effects, adverse events or other properties or safety risks, which could delay or preclude approval, cause us to suspend or discontinue clinical trials, abandon a product candidate, limit the commercial profile of the approved labeling, or result in other significant negative consequences that could severely harm our business, prospects, operating results and financial condition.

•

Even though FDA has approved Gimoti for the relief of symptoms in adults with acute and recurrent diabetic gastroparesis, we will remain subject to significant post-marketing regulatory requirements and oversight.

•

It will be difficult for us to profitably sell Gimoti if coverage and reimbursement are limited.

•

We rely and will continue to rely on outsourcing arrangements for many of our activities, including commercialization activities and supply of Gimoti.

•

We face substantial competition, which may result in others selling their products more effectively than we do, and in others discovering, developing or commercializing product candidates before, or more successfully, than we do.

•

It is difficult and costly to protect our intellectual property rights, and we cannot ensure the protection of these rights. Any impairment of our intellectual property rights may materially affect our business.

•

Claims by third parties that we infringe their proprietary rights may result in liability for damages or prevent or delay our developmental and commercialization efforts.

•

Our recurring losses from operations have raised substantial doubt regarding our ability to continue as a going concern.

•

We have incurred significant operating losses since inception, and we expect to incur losses for the foreseeable future. We may never become profitable or, if achieved, be able to sustain profitability.

•

If we fail to meet all applicable Nasdaq Capital Market requirements and Nasdaq determines to delist our common stock, the delisting could adversely affect the market liquidity of our common stock and the market price of our common stock could decrease.

The aggregate number of shares underlying each series of warrants is equal to 11,029,411 shares of Common Stock for a total of 33,088,233 shares underlying the Series A Warrants, Series B Warrants and Series C Warrants.   The Series A Warrants, Series B Warrants, and Series C Warrants have an exercise price per share equal to $0.68, which is equal to 100% of the price per Common Stock Unit sold in the offering. The Series A Warrants and Series B Warrants are exercisable immediately, subject to certain limitations described herein. The Series C Warrants may only be exercised to the extent and in proportion to a holder of the Series C Warrants exercising its corresponding Series B Warrants. The Series A Warrants will expire five years from the closing date of this offering. The Series B Warrants will expire nine months from the closing date of this offering. The Series C Warrants will also expire nine months from the closing date of this offering, provided that to the extent and in proportion to a holder of the Series C Warrants exercising its corresponding Series B Warrants included in the Common Stock Unit, such Series C Warrant will expire five years from the closing date of this offering. The shares of common stock in the Common Stock Units or the Pre-Funded Warrants in the PFW Units, as applicable, and the accompanying Common Warrants, can only be purchased together in this offering but will be issued separately and will be immediately separable upon issuance, provided that a Series C Warrant may not be separated from the corresponding Series B Warrant until such Series B Warrant has been exercised. This offering also relates to the offering of the shares of common stock issuable upon exercise of the Common Warrants. The exercise price and number of shares of common stock issuable upon exercise will be subject to certain further adjustments as described herein See “Description of Units” on page 18 of this prospectus.
 
Each Common Warrant is exercisable for one share of our common stock (subject to adjustment as provided therein) at any time at the option of the holder, provided that the holder will be prohibited from exercising its Common Warrant for shares of our common stock if, as a result of such exercise, the holder, together with its affiliates, would own more than 4.99% (or, at the election of the purchaser, 9.99%, 14.99%, or 19.99%) of the total number of shares of our common stock then issued and outstanding. However, any holder may increase such percentage to any other percentage not in excess of 19.99%, provided that any increase in such percentage shall not be effective until 61 days after such notice to us.

     Common stock to be outstanding immediately after this offering

     8,477,801 shares, assuming none of the Pre-Funded Warrants or Common Warrants issued in this offering are exercised.

Market symbol and trading	Our common stock is listed on The Nasdaq Capital Market under the symbol “EVOK”. There is no established trading market for the Common Warrants or the Pre-Funded Warrants and we do not expect a market to develop. In addition, we do not intend to apply for the listing of the Common Warrants or Pre-Funded Warrants on any national securities exchange or other trading market. Without an active trading market, the liquidity of the Common Warrants and Pre-Funded Warrants will be limited.

The number of shares of our common stock that will be outstanding immediately after this offering as shown above is based on 3,343,070 shares outstanding as of September 30, 2023. The number of shares outstanding as of September 30, 2023 as used throughout this prospectus, unless otherwise indicated, excludes:

•

639,601 shares of common stock issuable upon the exercise of options outstanding as of September 30, 2023, at a weighted average exercise price of $14.09 per share;

•

677,850 shares of common stock reserved for future issuance under our 2013 equity incentive award plan and our 2013 employee stock purchase plan as of September 30, 2023.

Unless otherwise indicated, all information in this prospectus assumes or gives effect to:

•

no exercise of any outstanding options referred to above; and

•

no exercise of the Pre-Funded Warrants, the Common Warrants or the warrants to be issued to the underwriters issued in this offering.

You should consider carefully the risks described below and discussed under the section captioned “Risk Factors” contained in our Annual Report on Form 10-K for the year ended December 31, 2022, as amended by our Quarterly Reports on Form 10-Q as may be further amended, supplemented or superseded from time to time by our subsequent filings under the Exchange Act which are incorporated by reference in this prospectus in their entirety, together with other information in this prospectus and the information and documents incorporated by reference in this prospectus, and any free writing prospectus that we have authorized for use in connection with this offering before you make a decision to invest in our securities. If any of the following events actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected. This could cause the trading price of our common stock to decline and you may lose all or part of your investment. The risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business operations.

Our operations have consumed substantial amounts of cash since inception. We believe, based on our current operating plan, that our cash and cash equivalents as well as future cash flows from net sales of Gimoti, together with the net proceeds from this offering, will be sufficient to fund our operations for at least the next twelve months. This estimate of cash runway could be shortened if there are any significant increases in planned spending on commercialization activities, including for marketing and manufacturing of Gimoti, and our selling, general and administrative costs to support operations, or as a result of any termination of the Eversana Agreement. As of September 30, 2023, we and Eversana each have the right to exercise the Net Profit Quarterly Termination Right and terminate the Eversana Agreement, which right either party may exercise for a 60-day period following the end of the quarter. We and Eversana will continue to have the option to exercise this termination right for the 60-day period following the end of future quarters so long as the net profit under the agreement remains negative for consecutive quarters. If the Net Profit Quarterly Termination Right is exercised, the outstanding principal and interest under the Eversana Credit Facility would be due within 90 days after the effective date of such termination. This would materially and adversely affect our near-term liquidity needs and cash runway. Even if this offering is successful, we anticipate that we will be required to raise additional funds through debt, equity or other forms of financing, such as potential collaboration arrangements, to fund future operations and continue as a going concern. There can be no assurance that we will be able to raise additional funds on acceptable terms, or at all. Because our business is entirely dependent on the success of Gimoti, if we are unable to secure additional financing, successfully commercialize Gimoti or identify and execute on other commercialization or strategic alternatives for Gimoti or our Company, we will be required to curtail all of our activities and may be required to liquidate, dissolve or otherwise wind down our operations. Any of these events could result in a complete loss of your investment in our securities.

Our estimates of the amount of cash necessary to fund our activities may prove to be wrong and we could spend our available financial resources much faster than we currently expect. Our future funding requirements will depend on many factors, including, but not limited to:

We are authorized to issue up to 50,000,000 shares of common stock. As of December 31, 2023, we had 3,343,070 shares of common stock outstanding and have reserved an aggregate of 1,317,451 shares of common stock for issuance under our equity incentive award plan and employee stock purchase plan. Assuming we sell all of the Common Stock Units or PFW Units we propose to sell in this offering, we will have a very limited number of remaining unreserved and authorized shares available for issuance, which will impact our ability to raise additional funds in the future.

Additional funding may not be available to us on acceptable terms or at all. In addition, the terms of any financing may adversely affect the holdings or the rights of our stockholders. Furthermore, the issuance of additional shares or other securities by us, or the possibility of such issuance, may cause the market price of our shares to decline and dilute the holdings of our existing stockholders. If we raise additional funds by incurring debt, the terms of the debt may involve significant cash payment obligations, as well as covenants and specific financial ratios that may restrict our ability to operate our business. We cannot provide any assurance that our existing capital resources, even after taking into account the proceeds of this offering, will be sufficient to enable us to continue the commercialization of Gimoti or to otherwise continue as a going concern.

If you purchase our securities sold in this offering, you will experience immediate and substantial dilution in the net tangible book value of your shares. In addition, we may issue additional equity or convertible debt securities in the future, which may result in additional dilution to investors.

Based on a public offering price of $0.68 per Common Stock Unit, and our as adjusted net tangible book value per share as of September 30, 2023, if you purchase securities in this offering, you will experience a decrease of $0.06 per share in the net tangible book value of the common stock you purchase representing the difference between our as adjusted net tangible book value per share after giving effect to this offering and the public offering price per share of common stock. The exercise of outstanding stock options and warrants, including those sold in this offering, will, however, result in dilution of your investment. In addition, to the extent we need to raise additional capital in the future and we issue additional shares of common stock or securities exercisable, convertible or exchangeable for our common stock, our then existing stockholders may experience dilution and the new securities may have rights senior to those of our common stock offered in this offering. See the section titled “Dilution” below for a more detailed illustration of the dilution you would incur if you participate in this offering.

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

Our management will have broad discretion in the application of our existing cash and cash equivalents and the net proceeds from this offering, including for any of the purposes described in the section titled “Use of Proceeds,” and you will not have the opportunity as part of your investment decision to assess whether such proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of our existing cash and cash equivalents and the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. Our management might not apply our existing cash and cash equivalents and the net proceeds from this offering in ways that ultimately increase the value of your investment. The failure by our management to apply these funds effectively could harm our business. Pending their use, we may invest the net proceeds from this

offering in short- and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government. These investments may not yield a favorable return to our stockholders. If we do not invest or apply the net proceeds from this offering in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.

The sale of our common stock in this offering, including any shares issuable upon exercise of any Pre-Funded Warrants or Common Warrants, and any future sales of our common stock, or the perception that such sales could occur, may depress our stock price and our ability to raise funds in new stock offerings.

We may from time-to-time issue additional shares of common stock at a discount from the current trading price of our common stock. As a result, our stockholders would experience immediate dilution upon the purchase of any shares of our common stock sold at such discount. In addition, as opportunities present themselves, we may enter into financing or similar arrangements in the future, including the issuance of debt securities, preferred stock or common stock. Sales of shares of our common stock in this offering, including any shares issuable upon exercise of any Pre-Funded Warrants or Common Warrants issued in this offering and in the public market following this offering, or the perception that such sales could occur, may lower the market price of our common stock and may make it more difficult for us to sell equity securities or equity-related securities in the future at a time and price that our management deems acceptable, or at all.

There is no public market for the Pre-Funded Warrants or Common Warrants being offered in this offering.

There is no established public trading market for the Pre-Funded Warrants or Common Warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the Pre-Funded Warrants or Common Warrants on any securities exchange or nationally recognized trading system, including Nasdaq. Without an active market, the liquidity of the Pre-Funded Warrants and the Common Warrants will be limited.

We may not receive any additional funds upon the exercise of the Pre-Funded Warrants or Common Warrants.

Each Pre-Funded Warrant may be exercised by way of a cashless exercise, meaning that the holder may not pay a cash purchase price upon exercise, but instead would receive upon such exercise the net number of shares of our common stock determined according to the formula set forth in the Pre-Funded Warrants. Accordingly, we may not receive any additional funds upon the exercise of the Pre-Funded Warrants.

Each Common Warrant (other than the Series B Warrant) may be exercised by way of a cashless exercise if at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of our common stock issuable upon exercise of the Common Warrants to the holder.

Significant holders or beneficial holders of our common stock may not be permitted to exercise Pre-Funded Warrants that they hold.

A holder of a Pre-Funded Warrant will not be entitled to exercise any portion of any Pre-Funded Warrants which, upon giving effect to such exercise, would cause the aggregate number of shares of our common stock beneficially owned by the holder (together with its affiliates) to exceed 4.99% (or, at the election of the purchaser, 9.99%, 14.99%, or 19.99%) of the number of shares of our common stock outstanding immediately after giving effect to the exercise. Such percentage may be increased or decreased by written notice by the holder of the Pre-Funded Warrants to any other percentage not in excess of 9.99%, 14.99%, or 19.99%. Such increase or decrease will not be effective until the sixty-first (61st) day after such notice is delivered to us. As a result, you may not be able to exercise your Pre-Funded Warrants for shares of our common stock at a time when it would be financially beneficial for you to do so. In such circumstance you could seek to sell your Pre-Funded Warrants to realize value, but you may be unable to do so in the absence of an established trading market for the Pre-Funded Warrants.

The Series A Warrants, Series B Warrants, and Series C Warrants have an exercise price per share equal to $0.68, which is equal to 100% of the price per Common Stock Unit sold in the offering. The Series A Warrants will expire five years from the closing date of this offering. The Series B Warrants will expire nine months from the closing date of this offering. The Series C Warrants will also expire nine months from the closing date of this offering, provided

that to the extent and in proportion to a holder of the Series C Warrants exercising its corresponding Series B Warrants included in the Common Stock Unit, such Series C Warrant will expire five years from the closing date of this offering. Upon such dates, the Common Warrants will expire and have no further value. In the event that the market price of our common stock does not exceed the exercise price of the Common Warrants during the period when they are exercisable, the Common Warrants may not have any value.

Holders of Pre-Funded Warrants and Common Warrants purchased in this offering will have no rights as common stockholders until such holders exercise their Pre-Funded Warrants or Common Warrants and acquire our common stock.

Until holders of Pre-Funded Warrants or Common Warrants acquire shares of our common stock upon exercise of such warrants, holders of Pre-Funded Warrants and Common Warrants will have no rights with respect to the shares of our common stock underlying such Pre-Funded Warrants and Common Warrants. Upon exercise of the Pre-Funded Warrants and Common Warrants, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

Our common stock is listed on The Nasdaq Capital Market. In order to maintain our listing, we must meet minimum financial and other requirements, including requirements for a minimum amount of capital, a minimum closing bid price per share of $1.00 and continued business operations so that we are not characterized as a “public shell company.”

On May 24, 2023, we received a written notice from Nasdaq indicating that, based on our stockholders’ equity of $2.1 million as of March 31, 2023, as reported in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2023, we were not in compliance with the minimum stockholders’ equity requirement for continued listing on The Nasdaq Capital Market under Nasdaq Listing Rule 5550(b)(1) (the “Minimum Stockholders’ Equity Requirement”). As required by Nasdaq, we submitted our plan to regain compliance with the Minimum Stockholders’ Equity Requirement and Nasdaq granted us an extension until November 20, 2023 to regain compliance. Following notice on November 21, 2023 from Nasdaq that we had not met the Minimum Stockholders’ Equity Requirement, we requested a hearing before the Nasdaq Hearings Panel (the “Hearings Panel”) and on December 9, 2023, Nasdaq notified the Company that the hearing was scheduled for February 15, 2024. On February 7, 2024, we received a request from Nasdaq for us to provide additional pro forma financial information and future forecasts at the Hearings Panel in order to evidence compliance with the Minimum Stockholders’ Equity Requirement. We do not currently expect the net proceeds from this offering to satisfy the Minimum Stockholders’ Equity Requirement on a pro forma basis. There can be no assurance that the Hearings Panel will grant our request for continued listing or that we will be able to evidence compliance prior to the expiration of any extension that may be granted by the Hearings Panel. Nasdaq has indicated in no event would such extension be granted, if at all, beyond May 20, 2024 under its rules. If the Hearings Panel does not grant our request for continued listing, we will be subject to delisting from The Nasdaq Capital Market. Even if the Hearings Panel grants an extension, there can be no assurances that we will regain compliance with the Minimum Stockholders’ Equity Requirement to the satisfaction of Nasdaq currently or in any future periods, even applying the expected proceeds of this offering, or meet the other Nasdaq continued listing requirements. For example, we may be unable to demonstrate to Nasdaq that we will continue to meet the Minimum Stockholders’ Equity Requirement through the current quarter or through December 31, 2024, based on the amount raised in this offering or our future revenue forecast assumptions, financing plans or otherwise. Further, even if we regain compliance with the Minimum Stockholders’ Equity Requirement, we may not be able to maintain compliance which may cause Nasdaq to delist our shares.

In the event that our common stock is delisted from the Nasdaq Capital Market and is not eligible for quotation or listing on another market or exchange, trading of our common stock could be conducted only in the over-the-counter market. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our common stock, and there would likely also be a reduction in our coverage by securities analysts and the news media, which

could cause the price of our common stock to decline further. Also, it may be difficult for us to raise additional capital if we are not listed on a major exchange.

These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. This prospectus and the documents incorporated by reference herein also contain estimates and other statistical data made by independent parties and by us relating to market size and growth and other data about our industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, projections, assumptions and estimates of our future performance and the future performance of the markets in which we operate are necessarily subject to a high degree of uncertainty and risk.

In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these terms or other similar expressions. The forward-looking statements in this prospectus and the documents incorporated by reference herein are only predictions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations.

The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. Given these risks and uncertainties, you should not place undue reliance on these forward-looking statements.

We estimate the net proceeds from this offering will be approximately $6.1 million based on public offering price of $0.68 per Common Stock Unit and $0.6799 per PFW Unit, after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. These estimates exclude the proceeds, if any, from the exercise of Common Warrants and Pre-Funded Warrants sold in this offering.

We currently intend to use the net proceeds from this offering, together with our existing cash and cash equivalents, for working capital and general corporate purposes, including for commercialization activities. We may also use a portion of the net proceeds, together with our existing cash and cash equivalents, to in-license, acquire, or invest in complementary businesses, technologies, products or assets; however, we have no current commitments or obligations to do so.

We believe, based on our current operating plan, that our cash and cash equivalents as well as future cash flows from net sales of Gimoti, together with the net proceeds from this offering, will be sufficient to fund our operations for the next 12 months. However, the amounts and timing of our actual expenditures will depend on numerous factors, including the amount of future Gimoti sales, any unexpected increases in planned spending on commercialization activities, including as a result of any termination of the Eversana Agreement or otherwise for marketing and manufacturing of Gimoti, and our general and administrative costs to support operations, and other factors described under “Risk Factors” in this prospectus and in the documents incorporated by reference herein, as well as the amount of cash used in our operations. We therefore cannot estimate with certainty the amount of net proceeds to be used for the purposes described above. We may find it necessary or advisable to use the net proceeds for other purposes, and we will have broad discretion in the application of the net proceeds. Pending the uses described above, we plan to invest the net proceeds from this offering in short- and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.

We have never declared or paid any cash dividends on our capital stock. We intend to retain future earnings, if any, to finance the operation of our business and do not anticipate paying any cash dividends in the foreseeable future. Any future determination related to our dividend policy will be made at the discretion of our board of directors after considering our financial condition, results of operations, capital requirements, business prospects and other factors our board of directors deems relevant, and subject to the restrictions contained in any future financing instruments.

If you invest in our securities in this offering, your ownership interest will be immediately diluted to the extent of the difference between the public offering price per Common Stock Unit and the as adjusted net tangible book value per share of our common stock immediately after this offering.

Historical net tangible book value (deficit) per share is determined by dividing our total tangible assets less our total liabilities by the total number of shares of common stock outstanding. Our historical net tangible book value (deficit) as of September 30, 2023 was approximately ($0.9) million, or ($0.26) per share, based on 3,343,070 shares of common stock outstanding as of that date.

After giving effect to the sale of 5,134,731 Common Stock Units, at a public offering price of $0.68 per Common Stock Unit, and 5,894,680 PFW Units at a public offering price of $0.6799 per PFW Unit, and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2023, which excludes shares of common stock underlying the Pre-Funded Warrants, would have been approximately $5.3 million, or $0.62 per share. This represents an immediate increase in as adjusted net tangible book value of $0.88 per share to our existing stockholders and an immediate dilution of $0.06 per share to new investors purchasing shares of our securities in this offering.

The following table illustrates this dilution to new investors on a per share basis:

The foregoing tables and calculations (other than the historical net tangible book value calculation) are based on 3,343,070 shares of common stock outstanding as of September 30, 2023, and exclude:

Assuming the Pre-Funded Warrants were immediately and fully exercised, this would result in an as adjusted net tangible book value per share after this offering of $5.3 million, or $0.37 per share of common stock, which represents a dilution per share to new investors of $0.31, and an increase in net tangible book value per share to existing stockholders of $0.63.

To the extent that any outstanding options or warrants described above are exercised, new options are issued, or we issue additional shares of common stock or other equity or convertible debt securities in the future, there will be further dilution to investors participating in this offering.

We are offering 5,134,731 Common Stock Units, each consisting of: (i) one share of our common stock, (ii) a Series A Warrant to purchase one share of our common stock, (iii) a Series B Warrant to purchase one share of our common stock, and (iv) a Series C Warrant to purchase one share of our common stock. The Series A Warrants, Series B Warrants and Series C Warrants are collectively referred to the as the “Common Warrants.”

Under the terms of our Certificate of Incorporation, holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders, including the election of directors, and do not have cumulative voting rights. Accordingly, the holders of a majority of the outstanding shares of common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they so choose, other than any directors that holders of any preferred stock we may issue may be entitled to elect.

Subject to preferences that may be applicable to any then outstanding preferred stock, holders of our common stock are entitled to receive ratably those dividends, if any, as may be declared by the board of directors out of legally available funds.

In the event of our liquidation, dissolution or winding up, the holders of our common stock will be entitled to share ratably in the assets legally available for distribution to stockholders after the payment of or provision for all of our debts and other liabilities, subject to the prior rights of any preferred stock then outstanding.

Holders of our common stock have no preemptive or conversion rights or other subscription rights and there are no redemption or sinking funds provisions applicable to the common stock. The rights, preferences and privileges of holders of our common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

All outstanding shares of our common stock are duly authorized, validly issued, fully paid and nonassessable.

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

Some provisions of Delaware law, our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that could make the following transactions more difficult: an acquisition of us by means of a tender offer; an acquisition of us by means of a proxy contest or otherwise; or the removal of our incumbent officers and directors. It is possible that these provisions could make it more difficult to accomplish or

could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions which provide for payment of a premium over the market price for our shares.

These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of the increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

The ability of our board of directors, without action by the stockholders, to issue up to 5,000,000 shares of undesignated preferred stock with voting or other rights or preferences as designated by our board of directors could impede the success of any attempt to change control of us. These and other provisions may have the effect of deferring hostile takeovers or delaying changes in control or management of our company.

Our amended and restated bylaws provide that a special meeting of stockholders may be called only by our chairperson of the board, chief executive officer or president, or by a resolution adopted by a majority of our board of directors.

Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals to be brought before a stockholder meeting and the nomination of candidates 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.

Our amended and restated certificate of incorporation and amended and restated bylaws eliminate the right of stockholders to act by written consent without a meeting.

Our board of directors is divided into three classes. The directors in each class serve for a three-year term, one class being elected each year by our stockholders. This system of electing and removing directors may tend to discourage a third-party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of the directors.

Our amended and restated certificate of incorporation provides that no member of our board of directors may be removed from office by our stockholders except for cause and, in addition to any other vote required by law, upon the approval of not less than 66 2/3% of the total voting power of all of our outstanding voting stock then entitled to vote in the election of directors.

Our amended and restated certificate of incorporation does not permit stockholders to cumulate their votes in the election of directors. Accordingly, the holders of a majority of the outstanding shares of our common stock

entitled to vote in any election of directors can elect all of the directors standing for election, if they choose, other than any directors that holders of our preferred stock may be entitled to elect.

We are subject to Section 203 of the DGCL, which prohibits persons deemed to be “interested stockholders” from engaging in a “business combination” with a publicly held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the board of directors.

The amendment of any of the above provisions, except for the provision making it possible for our board of directors to issue preferred stock, would require approval by holders of at least 66 2/3% of the total voting power of all of our outstanding voting stock.

The provisions of Delaware law, our amended and restated certificate of incorporation and our amended and restated bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in the composition of our board and management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

The term “pre-funded” refers to the fact that the purchase price of the Pre-Funded Warrants in this offering includes almost the entire exercise price that will be paid under the Pre-Funded Warrants, except for a nominal remaining exercise price of $0.0001. The purpose of the Pre-Funded Warrants is to enable investors that may have restrictions on their ability to beneficially own more than 4.99% (or, at the election of such purchaser, 9.99%, 14.99%, or 19.99%) of our outstanding common stock following the consummation of this offering the opportunity to invest capital into the Company without triggering their ownership restrictions, by receiving Pre-Funded Warrants in lieu of shares of our common stock which would result in such ownership of more than 4.99%, 9.99%, 14.99%, or 19.99%, as applicable, and receiving the ability to exercise their option to purchase the shares underlying the Pre-Funded Warrants at a nominal price at a later date.

The following is a brief summary of certain terms and provisions of the Pre-Funded Warrants being offered by us. The following description is not complete and is subject in all respects to the provisions of the Pre-Funded Warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of Pre-Funded Warrant for a complete description of the terms of the Pre-Funded Warrants.

Pre-Funded Warrants have an exercise price of $0.0001 per share. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock and also upon any distributions of assets, including cash, stock or other property to our stockholders.

The Pre-Funded Warrants are immediately exercisable and do not expire until exercised in full. The Pre-Funded Warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice accompanied by payment in full of the exercise price in immediately available funds for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below).

The Pre-Funded Warrants may not be exercised by the holder to the extent that the holder, together with its affiliates, would beneficially own, after such exercise more than 4.99% of the shares of our common stock then outstanding (including for such purpose the shares of our common stock issuable upon such exercise). However, any holder may increase or decrease such beneficial ownership limitation upon notice to us, provided that such limitation cannot exceed 19.99%, and provided that any increase in the beneficial ownership limitation shall not be effective until 61 days after such notice is delivered. Purchasers of Pre-Funded Warrants in this offering may also elect prior to the issuance of the Pre-Funded Warrants to have the initial exercise limitation set at 9.99%, 14.99%, or 19.99% of our outstanding shares of common stock.

In lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder of a Pre-Funded Warrant may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the Pre-Funded Warrants.

Subject to applicable laws, the Pre-Funded Warrants may be transferred at the option of the holder upon surrender of the Pre-Funded Warrant to us together with the appropriate instruments of transfer.

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

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

Except as otherwise provided in the Pre-Funded Warrants or by virtue of the holders’ ownership of shares of our common stock, the holders of warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until such warrant holders exercise their Pre-Funded Warrants.

In the event of a fundamental transaction, as described in the Pre-Funded Warrants and generally including any reorganization, recapitalization or reclassification of our common stock, 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 common stock, or any person or group becoming the beneficial owner of more than 50% of the voting power represented by our outstanding common stock, upon consummation of such a fundamental

transaction, the holders of the Pre-Funded Warrants will be entitled to receive upon exercise of the Pre-Funded Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Pre-Funded Warrants immediately prior to such fundamental transaction without regard to any limitations on exercise contained in the Pre-Funded Warrants.

No term of the Pre-Funded Warrants may be amended or waived without the written consent of the holder of such Pre-Funded Warrant.

The following is a brief summary of certain terms and provisions of the Common Warrants being offered by us. The following description is not complete and is subject in all respects to the provisions of each series of Common Warrant, the forms of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the forms of each series of Common Warrant for a complete description of the terms and conditions of the Common Warrants.

Each Series A Warrant, Series B Warrant, and Series C Warrant offered hereby has an exercise price per share equal to $0.68 (representing 100% of the price per share of the common stock sold in the offering). The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock and also upon any distributions of assets, including cash, stock or other property to our stockholders.

The Series A Warrants are immediately exercisable and will expire five years following the date of issuance. The Series B Warrants are immediately exercisable and will expire nine months following the date of issuance. The Series C Warrants will become exercisable only to the extent and in proportion to a holder of the Series C Warrants exercising its corresponding Series B Warrants included in a Unit. The Series C Warrant will expire nine months following the date of issuance, provided that to the extent and in proportion to a holder of the Series C Warrants exercising its corresponding Series B Warrants included in a Unit, such Series C Warrant will expire five years following the date of issuance. Each series of Common Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full of the exercise price in immediately available funds for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below).

The Common Warrants may not be exercised by the holder to the extent that the holder, together with its affiliates, would beneficially own, after such exercise more than 4.99% of the shares of our common stock then outstanding (including for such purpose the shares of our common stock issuable upon such exercise). However, any holder may increase or decrease such beneficial ownership limitation upon notice to us, provided that such limitation cannot exceed 19.99%, and provided that any increase in the beneficial ownership limitation shall not be effective until 61 days after such notice is delivered. Purchasers of Common Warrants in this offering may also elect prior to the issuance of the Common Warrants to have the initial exercise limitation set at 9.99%, 14.99%, or 19.99% of our outstanding shares of common stock.

If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the shares of common stock issuable upon exercise of the Series A or Series C Warrants, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the Series A Warrants and Series C Warrants.

Subject to applicable laws, a Series A Warrant may be transferred at the option of the holder upon surrender of the Series A Warrant to us together with the appropriate instruments of transfer. A Series B Warrant may not be transferred during its term except with our consent. A Series C Warrant may not be transferred during its term except with our consent; provided that a Series C Warrant may be transferred without our consent after the corresponding Series B Warrant included in a Unit has been exercised, but only to the extent and in proportion to the exercise of such corresponding Series B Warrant. A Series C Warrant that is transferable may be transferred at the option of the holder upon surrender of the Series C Warrant to us together with the appropriate instruments of transfer.

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

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

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

In the event of a fundamental transaction, as described in the Common Warrants and generally including any reorganization, recapitalization or reclassification of our common stock, 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 common stock, or any person or group becoming the beneficial owner of more than 50% of the voting power represented by our outstanding common stock, upon consummation of such a fundamental transaction, the holders of the Common Warrants will be entitled to receive upon exercise of the Common Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Common Warrants immediately prior to such fundamental transaction without regard to any limitations on exercise contained in the Common Warrants.

Notwithstanding the foregoing, in the event of a fundamental transaction, we or a successor entity shall, at the holder’s option, exercisable at any time concurrently or within thirty (30) days following the consummation of a fundamental transaction, purchase the Common Warrant by paying to the holder an amount equal to the Black Scholes Value (as defined in each Common Warrant) of the remaining unexercised portion of the Common Warrant on the date of the fundamental transaction. If the fundamental transaction is not within our control, the holders of the Common Warrants will only be entitled to receive from us or a successor entity the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of the Common Warrant, that is being offered and paid to the holders of our common stock in connection with the fundamental transaction, whether

that consideration is in the form of cash, stock or any combination thereof, or whether the holders of our common stock are given the choice to receive alternative forms of consideration in connection with the fundamental transaction.

No term of the Common Warrants may be amended or waived without the written consent of the holder of such Common Warrant.

Our named executive officers for 2023, which consist of our principal executive officer during 2023 and our two next most highly compensated executive officers during 2023, were:

This discussion may contain forward-looking statements that are based on our current plans, considerations, expectations, and determinations regarding future compensation programs. Actual compensation programs that we adopt following the closing of this offering may differ materially from the currently planned programs summarized in this discussion.

The following table sets forth information regarding compensation earned with respect to the fiscal years ended December 31, 2022 and 2023 by our named executive officers.

The following table shows information regarding the compensation earned by our named executive officers during the fiscal years ended December 31, 2023 and 2022:

In general, base salaries for our named executive officers are initially established through arm’s length negotiation at the time the executive is hired, taking into account such executive’s qualifications, experience and prior salary. Base salaries of our named executive officers are approved and reviewed annually by our compensation committee and adjustments to base salaries are based on the scope of an executive’s responsibilities, individual contribution, prior experience and sustained performance. Decisions regarding salary increases may take into account an executive officer’s current salary, equity ownership, and the amounts paid to an executive officer’s peers inside our company by conducting an internal analysis, which compares the pay of an executive officer to other members of the management team. Base salaries are also reviewed in the case of promotions or other significant changes in responsibility. Base salaries are not automatically increased if the board of directors and compensation committee believe that other elements of the named executive officer’s compensation are more appropriate in light of our stated objectives. This strategy is consistent with our intent of offering compensation that is both cost-effective, competitive and contingent on the achievement of performance objectives.

The actual base salaries paid to all of our named executive officers for 2023 are set forth in the “Summary Compensation Table” above.

In February 2023, our compensation committee approved base salary increases for 2023 for Messrs. Gonyer and D’Onofrio and Dr. Carlson to $595,000, $450,000, and $420,000, respectively. These base salary increases represented adjustments of approximately 4.4 %, 7.9% and 4.5%, respectively.

The base salaries of our named executive officers continue to be below the median level of similarly-situated executives for our peer group of companies.

Each named executive officer is also eligible for a performance bonus based upon the achievement of certain corporate performance goals and objectives approved by our compensation committee and board of directors.

Bonuses are set based on a percentage of the executive’s base salary as of the end of the bonus year and are expected to be paid out in the first quarter of the following year. The target levels for 2023 executive bonuses were as follows: 60% for our Chief Executive Officer, 50% for our President and Chief Operating Officer, and 45% for our Chief Medical Officer. The executive bonuses are 100% based on the achievement of corporate objectives that are set each year by the board of directors and the compensation committee. All final bonus payments to our named executive officers are determined by our compensation committee. The actual bonuses awarded in any year, if any, may be more or less than the target, depending on individual performance and the achievement of corporate objectives and may also vary based on other factors at the discretion of the compensation committee.

For 2023, the corporate performance objectives for our named executive officers were related to corporate financial objectives. Bonuses for any one year are usually determined and paid in the first quarter of the following year. Accordingly, bonus compensation for our named executive officers for 2023 has not yet been determined as of the date of filing of this prospectus.

The overall achievement level was then used to determine each named executive officer’s bonus. The bonuses paid to our named executive officers for 2023 are set forth in the “Summary Compensation Table” above.

The goals of our long-term, equity-based incentive awards are to align the interests of our named executive officers and other employees, non-employee directors and consultants with the interests of our stockholders. Because vesting is based on continued employment, our equity-based incentives also encourage the retention of our named executive officers through the vesting period of the awards. In determining the size of the long-term equity incentives to be awarded to our named executive officers, we take into account a number of internal factors, such as the relative job scope, the value of existing long-term incentive awards, individual performance history, prior contributions to us and the size of prior grants. Our compensation committee reviews competitive market data prepared by APA in connection with its grant of long-term equity incentive awards to the named executive officers, but such awards are not determined by reference to any specific target level of compensation or benchmarking. Based upon these factors, the compensation committee determines the size of the long-term equity incentives at levels it considers appropriate to create a meaningful opportunity for reward predicated on the creation of long-term stockholder value. We have not granted any equity awards other than stock options to date.

To reward and retain our named executive officers in a manner that best aligns employees’ interests with stockholders’ interests, we use stock options as the primary incentive vehicles for long-term compensation. We believe that stock options are an effective tool for meeting our compensation goal of increasing long-term stockholder value by tying the value of the stock options to our future performance. Because employees are able to profit from stock options only if our stock price increases relative to the stock option’s exercise price, we believe stock options provide meaningful incentives to employees to achieve increases in the value of our stock over time.

The exercise price of each stock option grant is the fair market value of our common stock on the grant date, as determined by our board of directors from time to time. Stock option awards granted to our named executive officers generally vest on a monthly basis over a four-year period. From time to time, our compensation committee may, however, determine that a different vesting schedule is appropriate.

In February 2023, our named executive officers were granted stock options to purchase shares of our common stock. Specifically, Messrs. Gonyer and D’Onofrio and Dr. Carlson were granted options to purchase 30,000, 25,000, and 15,000 shares of our common stock, respectively. The options for Mr. Gonyer and Dr. Carlson vest on a monthly basis over a four-year period commencing January 1, 2023, while the options for Mr. D'Onofrio vest on the four-year anniversary of the grant date, subject to the reporting person’s continued service to the issuer through each such vesting date.

We have had no program, plan or practice pertaining to the timing of stock option grants to named executive officers coinciding with the release of material non-public information. Stock options granted to our named executive officers may be subject to accelerated vesting in certain circumstances. For additional discussion, please see “Employment Agreements.”

The following table sets forth specified information concerning unexercised stock options and unvested stock awards for each of the named executive officers outstanding as of December 31, 2023:

(1)

All of the options have a ten-year term from the original grant date (prior to giving effect to the stock option exchange in June 2019, which did not result in an extension of the original ten-year term of the options). The options granted on June 17, 2019 represent options granted to the named executive officers pursuant to the stock option exchange completed on June 17, 2019. The options surrendered pursuant to the stock option exchange completed on June 17, 2019 were exchanged for a new unvested option covering a lesser number of shares determined in accordance with the “exchange ratio” with an exercise price of $7.44 per share. All of the existing stock options that were surrendered by the employees had exercise prices significantly above the recent trading prices of our common stock and the average market price of our common stock over the prior 12 months. The new options vest monthly over four years, commencing June 17, 2019. Employees received three new options for every four eligible options surrendered, with this exchange ratio applied on a grant-by-grant basis and the resulting number of options rounded down to the nearest whole share. The new stock options retained the same expiration date as the surrendered stock options to which they related. The other terms and conditions of the new options are governed by the terms and conditions of our 2013 Equity Incentive Award Plan and the stock option agreements entered into thereunder.

We have entered into employment agreements with each of Messrs. Gonyer and D’Onofrio. Pursuant to the employment agreements, each executive's base salary is subject to review each year at the sole discretion of the compensation committee. The executives are eligible to earn an annual cash performance bonus under the company’s bonus plan or plans applicable to senior executives. The annual cash performance bonus payable is based on the achievement of individual and/or company performance goals to be determined in good faith by the compensation committee.

Pursuant to each of the employment agreements, if we terminate such officer’s employment without cause (as defined below), such officer resigns for good reason (as defined below) or such officer’s employment is terminated as a result of his or her death or following his or her permanent disability, the executive officer or his or her estate, as applicable, is entitled to the following payments and benefits: (1) fully earned but unpaid base salary through the date of termination at the rate then in effect, plus all other amounts under any compensation plan or practice to which he or she is entitled; (2) a lump sum cash payment in an amount equal to 12 months of his base salary as in effect immediately prior to the date of termination; (3) a lump sum cash payment in an amount equal to his or her bonus (as defined below) for the year in which the termination of his employment occurs, prorated for the period of his service during such year, provided that the officer shall not be entitled to receive such amount in the event that his termination results from his discharge by us without cause prior to a change in control (as defined below); (4) a lump sum cash payment in an amount equal to the cost of the continuation of health benefits for a period of 12 months following date of termination; (5) a lump sum cash payment in an amount equal to the cost of his life insurance premiums for a period of 12 months following the date of termination; (6) solely in the event of the officer’s termination by us without cause or by the officer for good reason, a lump sum cash payment in an amount equal to $15,000 for outplacement service; and (7) the automatic acceleration of the vesting and exercisability of outstanding unvested stock awards as to the number of stock awards that would have vested over the 12-month period following termination had such executive officer remained continuously employed by us during such period. In the event an officer’s termination without cause or resignation for good reason occurs within three months prior to the occurrence of a change in control or within 12 months following a change in control, all of his outstanding unvested stock awards will accelerate and become fully vested on the later of (1) the date of termination or (2) the date of such change in control.

We have also entered into an employment agreement with Dr. Carlson. Pursuant to the employment agreement, Dr. Carlson agrees to devote 80% of her productive time and efforts to the performance of her duties as Chief Medical Officer. Pursuant to the employment agreement, Dr. Carlson’s base salary is subject to review each year at the sole discretion of the compensation committee. Dr. Carlson is also eligible to earn an annual cash performance bonus under the company’s bonus plan or plans applicable to senior executives. The annual cash performance bonus payable is based on the achievement of individual and/or Company performance goals to be determined in good faith by the

compensation committee. The company also pays Dr. Carlson a taxable monthly payment equal to the monthly premium Dr. Carlson pays for healthcare coverage under Medicare, in an amount not to exceed $2,000 per month.

Pursuant to the employment agreement, if we terminate Dr. Carlson’s employment without cause (as defined below) or Dr. Carlson resigns for good reason (as defined below), Dr. Carlson is entitled to the following payments and benefits: (1) fully earned but unpaid base salary through the date of termination at the rate then in effect, plus all other amounts under any compensation plan or practice to which she is entitled; (2) a lump sum cash payment in an amount equal to her monthly base salary as in effect immediately prior to the date of termination for a period of nine months; (3) a lump sum cash payment in an amount equal to her bonus for the year in which the termination of her employment occurs, prorated for the period of her service during such year, provided that Dr. Carlson shall not be entitled to receive such amount in the event that her termination results from her discharge by the company without cause prior to a change in control (as defined below); and (4) a taxable monthly payment in an amount equal to her monthly healthcare coverage costs under Medicare as in effect immediately prior to the date of termination, in an amount not to exceed $2,000 per month, for a period of nine months.

In the event Dr. Carlson’s termination without cause or resignation for good reason occurs within three months prior to the occurrence of a change in control or within 12 months following a change in control, all of her outstanding unvested stock awards will accelerate and become fully vested on the later of (1) the date of termination or (2) the date of such change in control.

Dr. Carlson’s employment agreement also contains standard confidentiality, non-competition and non-solicitation covenants.

For purposes of the employment agreements with the named executive officers, “cause” generally means an executive officer’s (1) commission of an act of fraud, embezzlement or dishonesty that has a material adverse impact on us or any successor or affiliate of ours; (2) conviction of, or entry into a plea of “guilty” or “no contest” to, a felony; (3) unauthorized use or disclosure of our confidential information or trade secrets or any successor or affiliate of ours that has a material adverse impact on any such entity; (4) gross negligence, insubordination or material violation of any duty of loyalty, or any other material misconduct on the part of the executive officer; (5) ongoing and repeated failure or refusal to perform or neglect of his or her duties as required by his or her employment agreement, which failure, refusal or neglect continues for 15 days following his or her receipt of written notice from our board of directors stating with specificity the nature of such failure, refusal or neglect; or (6) breach of any material provision of his or her employment agreement.

For purposes of the employment agreements with the named executive officers, “good reason” generally means (1) other than for Dr. Carlson, a change in the executive officer’s status, position or responsibilities that, in the executive officer’s reasonable judgment, represents a substantial and material reduction in the status, position or responsibilities as in effect immediately prior thereto; the assignment to the executive officer of any duties or responsibilities that, in the executive officer’s reasonable judgment, are materially inconsistent with such status, position or responsibilities; or any removal of the executive officer from or failure to reappoint or reelect the executive officer to any of such positions, except in connection with the termination of the executive officer’s employment for cause (as defined above), as a result of his or her permanent disability or death, or by the executive officer other than for good reason; (2) with respect to Dr. Carlson, a material diminution in her authority, duties or responsibilities; (3) a material reduction in the executive officer’s annual base salary, except in connection with a general reduction in the compensation of our or any successor’s or affiliate’s personnel with similar status and responsibilities; (4) our or any successor’s or affiliate’s requirement the executive officer (without the executive officer’s consent) be based at any place outside a 50-mile radius of his or her placement of employment as of the effective date of the employment agreement, except for reasonably required travel for our or any successor’s or affiliate’s business that is not materially greater than such travel requirements prior to the effective date of the employment agreement; (5) any material breach by us or any successor or affiliate of obligations to the executive officer under the employment agreement; (6) other than for Dr. Carlson, any purported termination of the executive officer’s employment or service relationship for cause (as defined above) by us or any successor or affiliate that is not in accordance with the definition of cause; or (7) other than for Dr. Carlson, a change in control (as defined below).

For purposes of the employment agreements with the named executive officers, “bonus” generally means an amount equal to the greater of (1) the executive officer’s target bonus for the fiscal year in which the date of termination occurs; or (2) the bonus awarded to the executive officer for the fiscal year prior to the date of termination (which bonus shall be annualized to the extent the executive officer was not employed for the entire fiscal year prior to the date of termination). If any portion of the bonus awarded to the executive officer consisted of securities or other property, the fair market value thereof shall be determined in good faith by our board of directors.

For purposes of the employment agreements with the named executive officers, a “change in control” generally means:

We currently maintain a 401(k) retirement savings plan that allows eligible employees to contribute a portion of their compensation, within limits prescribed by the Internal Revenue Code, on a pre-tax basis through contributions to the plan. Our named executive officers are eligible to participate in the 401(k) plan. We believe that providing a vehicle for tax-deferred retirement savings through our 401(k) plan adds to the overall desirability of our executive compensation package and further incentivizes our named executive officers in accordance with our compensation policies.

Our named executive officers are eligible to participate in our health and welfare plans. We reimburse Dr. Carlson for her health care premiums and pay for the health and welfare benefits for our other named executive officers and our other four employees. We do not provide our named executive officers with any other significant perquisites or other personal benefits.

We maintain a compensation recovery policy that is compliant with the Nasdaq Listing Rules, as required by the Dodd-Frank Act.

The principal features of our equity incentive plans are summarized below. These summaries are qualified in their entirety by reference to the actual text of the applicable plan, each of which is filed as an exhibit to the registration statement of which this prospectus is a part.

Purpose. The purpose of our 2013 Equity Incentive Plan (the “2013 Plan”) is to promote our success and enhance our value by linking the individual interests of the members of the board of directors and our employees and consultants to those of our stockholders and by providing such individuals with an incentive for outstanding performance to generate superior returns to our stockholders. The 2013 Plan is further intended to provide us flexibility in our ability to motivate, attract, and retain the services of members of the board of directors, our employees and our consultants upon whose judgment, interest, and special effort the successful conduct of our operation is largely dependent.

Securities Subject to the 2013 Plan. As of December 31, 2023, a total of 1,172,070 shares of our common stock were authorized for issuance under the 2013 Plan. In addition, commencing on January 1, 2024 and on each January 1 thereafter during the ten-year term of the 2013 Plan, through and including January 1, 2033, the aggregate number of shares available for issuance under the 2013 Plan shall be increased by that number of shares of our common stock equal to the lesser of:

The number of shares of stock that may be issued or transferred pursuant to ISOs under the 2013 Plan may not exceed an aggregate of 50,000,000 shares. All of the foregoing share numbers may be adjusted for changes in our capitalization and certain corporate transactions, as described below under the heading “Adjustments.”

To the extent that an award lapses, expires, is forfeited or is settled for cash, any shares subject to the award will, to the extent of such lapse, expiration, forfeiture or cash settlement, be available for future grant or sale under the 2013 Plan. In addition, shares of common stock which are delivered by the holder or withheld by us in payment of the grant or exercise price or tax withholding obligation of any award under the 2013 Plan will again be available for future grant or sale under the 2013 Plan. If any shares of restricted stock are forfeited by a participant or repurchased by us pursuant to the 2013 Plan, such shares shall again be available for future grant or sale under the 2013 Plan. Any shares subject to a Stock Appreciation Right, or a SAR, that are not issued in connection with the stock settlement of the SAR on exercise thereof shall again be available for the grant of an award pursuant to the 2013 Plan. The payment of dividend equivalents in cash in conjunction with any outstanding awards shall not be counted against the shares of stock available for issuance under the plan.

Administration. The compensation committee of our board of directors administers the 2013 Plan (except with respect to any award granted to non-employee directors, which must be administered by our full board of directors). To administer the 2013 Plan, our compensation committee must consist solely of at least two members of our board of directors, each of whom is a “non-employee director” for purposes of Rule 16b-3 under the Exchange Act. Subject to the terms and conditions of the 2013 Plan, our compensation committee has the authority to select the persons to whom awards are to be made, to determine the type or types of awards to be granted to each person, the number of awards to grant, the number of shares to be subject to such awards, and the terms and conditions of such awards, and to make all other determinations and decisions and to take all other actions necessary or advisable for the administration of the 2013 Plan. Our compensation committee is also authorized to establish, adopt, amend or revise rules relating to administration of the 2013 Plan. Our board of directors may at any time revest in itself the authority to administer the 2013 Plan.

Eligibility. Options, SARs, restricted stock and other awards under the 2013 Plan may be granted to individuals who are our officers or employees or are the officers or employees of any of our subsidiaries. Such awards may also be granted to our non-employee directors and consultants, but only employees may be granted ISOs. The sum of any cash compensation, or other compensation, and the value (determined as of the grant date in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, or any successor thereto) of awards granted to a non-employee director as compensation for services as a non-employee director during any calendar year under the 2013 Plan may not exceed $400,000. The board of directors may make exceptions to this limit for individual non-employee directors in extraordinary circumstances, as the board of directors may determine in its discretion, provided that the non-employee director receiving such additional compensation may not participate in the decision to award such compensation or in other contemporaneous compensation decisions involving non-employee directors.

Awards. The 2013 Plan provides that our compensation committee (or the board of directors, in the case of awards to non-employee directors) may grant or issue stock options, SARs, restricted stock, restricted stock units, dividend equivalents, stock payments and performance awards, or any combination thereof. Our compensation committee (or the board of directors, in the case of awards to non-employee directors) will consider each award grant subjectively, considering factors such as the individual performance of the recipient and the anticipated contribution of the recipient to the attainment of our long-term goals. Each award will be set forth in a separate agreement with the person receiving the award and will indicate the type, terms and conditions of the award.

Stock payments may be authorized by our compensation committee (or our board of directors, in the case of awards to non-employee directors) in the form of common stock or an option or other right to purchase common stock as part of a deferred compensation arrangement, made in lieu of all or any part of compensation, including bonuses, that would otherwise be payable to employees, consultants or members of our board of directors.

Performance-Based Compensation. The compensation committee may grant to eligible recipients restricted stock, dividend equivalents, stock payments, restricted stock units, cash bonuses and other stock-based awards that are paid, vest or become exercisable upon the attainment of company performance criteria relating to our performance, the performance of a division, business unit or an individual, and may include but are not limited to the following: operating or other costs and expenses, improvements in expense levels, cash flow (including, but not limited to, operating cash flow and free cash flow), return on assets, return on capital, stockholders’ equity, return on stockholders’ equity, total stockholder return, return on sales, gross or net profit or operating margin, working capital, net earnings (either before or after interest, taxes, depreciation and amortization), gross or net sales or revenue, net income (either before or after taxes), adjusted net income, operating earnings, earnings per share of stock, adjusted earnings per share of stock, price per share of stock, regulatory body approval for commercialization of a product, capital raised in financing transactions or other financing milestones, market recognition (including but not limited to awards and analyst ratings), financial ratios, implementation or completion of critical projects, market share, economic value, comparisons with various stock market indices, and implementation, completion or attainment of objectively determinable objectives relating to research, development, regulatory, commercial or strategic milestones or development. These performance criteria may be measured in absolute terms or as compared to performance in an earlier period or as compared to any incremental increase or decrease or as compared to results of a peer group or to market performance indicators or indices.

The compensation committee may provide that one or more adjustments will be made to one or more of the performance goals established for any performance period. Such adjustments may include one or more of the following: items related to a change in accounting principle, items relating to financing activities, expenses for restructuring or productivity initiatives, other non-operating items, items related to acquisitions, items attributable to the business operations of any entity acquired by us during the performance period, items related to the disposal of a business or segment of a business, items related to discontinued operations that do not qualify as a segment of a business under applicable accounting standards, items attributable to any stock dividend, stock split, combination or exchange of shares occurring during the performance period, any other items of significant income or expense which are determined to be appropriate adjustments, items relating to unusual or extraordinary corporate transactions, events or developments, items related to amortization of acquired intangible assets, items that are outside the scope of our core, on-going business activities, items related to acquired in-process research and development, items relating to changes in tax laws, items relating to major licensing or partnership arrangements, items relating to asset impairment charges, items relating to gains and losses for litigation, arbitration or contractual settlements, or items relating to any other unusual or nonrecurring events or changes in applicable laws, accounting principles or business conditions.

Forfeiture, Recoupment and Clawback Provisions. Pursuant to its general authority to determine the terms and conditions applicable to awards under the 2013 Plan, the compensation committee has the right to provide, in an award agreement or otherwise, that an award shall be subject to the provisions of any recoupment or clawback policies implemented by us, including, without limitation, any recoupment or clawback policies adopted to comply with the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder.

Adjustments. If there is any stock dividend, stock split, combination or exchange of shares, merger, consolidation or other distribution (other than normal cash dividends) of our assets to stockholders, or any other change affecting the shares of our common stock or the share price of our common stock other than an equity restructuring (as defined in the 2013 Plan), the plan administrator will make such equitable adjustments, if any, as the plan administrator in its discretion may deem appropriate to reflect such change with respect to (1) the aggregate number and type of shares that may be issued under the 2013 Plan (including, but not limited to, adjustments of the number of shares available under the plan and the maximum number of shares which may be subject to one or more awards to a participant pursuant to the plan during any calendar year), (2) the number and kind of shares, or other securities or property, subject to outstanding awards, (3) the number and kind of shares, or other securities or property, for which automatic grants are to be subsequently made to new and continuing non-employee directors, (4) the terms and conditions of any outstanding awards (including, without limitation, any applicable performance targets or criteria with respect

thereto), and (5) the grant or exercise price per share for any outstanding awards under the 2013 Plan. If there is any equity restructuring, (1) the number and type of securities subject to each outstanding award and the grant or exercise price per share for each outstanding award, if applicable, will be proportionately adjusted, and (2) the plan administrator will make proportionate adjustments to reflect such equity restructuring with respect to the aggregate number and type of shares that may be issued under the 2013 Plan (including, but not limited to, adjustments of the number of shares available under the plan and the maximum number of shares which may be subject to one or more awards to a participant pursuant to the plan during any calendar year). Adjustments in the event of an equity restructuring will not be discretionary. The plan administrator also has the authority under the 2013 Plan to take certain other actions with respect to outstanding awards in the event of a corporate transaction, including provision for the cash-out, termination, assumption or substitution of such awards.

Corporate Transactions. In the event of a change in control where the acquirer does not assume or substitute awards granted under the 2013 Plan, awards issued under the 2013 Plan will be subject to accelerated vesting such that 100% of the awards will become vested and exercisable or payable, as applicable. Under the 2013 Plan, a change in control is generally defined as:

Amendment and Termination of the 2013 Plan. Our compensation committee or board of directors may terminate, amend or modify the 2013 Plan. However, stockholder approval of any amendment to the 2013 Plan will be obtained to the extent necessary and desirable to comply with any applicable law, regulation or stock exchange rule, or for any amendment to the 2013 Plan that increases the number of shares available under the 2013 Plan or that may be issued to an individual in any calendar year. If not terminated earlier by our compensation committee or board of directors, the 2013 Plan will terminate in March 2033 on the tenth anniversary of the date of its initial approval by our board of directors.

Repricing Permitted. Our compensation committee (or the board of directors, in the case of awards to non-employee directors) has the authority, without the approval of our stockholders, to authorize the amendment of any outstanding award to reduce its price per share and to provide that an award will be canceled and replaced with the grant of an award having a lesser price per share. Our compensation committee (or the board of directors, in the case of awards to non-employee directors) also has the authority, without the approval of our stockholders, to amend any outstanding award to increase the price per share or to cancel and replace an award with the grant of an award having a price per share that is greater than or equal to the price per share of the original award.

Purpose. The purpose of our 2013 Employee Stock Purchase Plan (the “ESPP”) is to assist our eligible employees in acquiring a stock ownership interest in our company and to help our eligible employees provide for their future security and to encourage them to remain in our employment.

Securities Subject to the ESPP. As of December 31, 2023, a total of 145,381 shares of our common stock are authorized for issuance under the ESPP. In addition, commencing on January 1, 2024 and on each January 1 thereafter through and including January 1, 2033, the aggregate number of shares available for issuance under the ESPP shall be increased by that number of shares of our common stock equal to the lesser of:

Not withstanding the foregoing, the number of shares of stock that may be issued or transferred pursuant to awards under the ESPP may not exceed an aggregate of 10,000,000 shares. All of the foregoing share numbers may be adjusted for changes in our capitalization and certain corporate transactions, as described below under the heading “Adjustments.”

Administration. Our board of directors or its committee has full and exclusive authority to interpret the terms of the ESPP and determine eligibility. Our compensation committee is the administrator of the ESPP.

Eligibility. Our employees are eligible to participate in the ESPP if they are customarily employed by us or any participating subsidiary for at least 20 hours per week and more than five months in any calendar year on the day prior to the first day of the offering period. However, an employee may not be granted rights to purchase stock under our ESPP if such employee, immediately after the grant, would own (directly or through attribution) stock possessing 5% or more of the total combined voting power or value of all classes of our common or other class of stock.

Eligible employees become participants in the ESPP by enrolling and authorizing payroll deductions by the deadline established by the administrator prior to the relevant offering date. Directors who are not employees are not eligible to participate. Employees who choose not to participate, or are not eligible to participate at the start of an offering period but who become eligible thereafter, may enroll in any subsequent offering period.

•

Enrollment; Contributions. Our ESPP permits participants to purchase common stock through payroll deductions of up to 20% of their eligible compensation, which includes a participant’s gross base compensation for services to the company, excluding overtime payments, sales commissions, incentive compensation, bonuses, expense reimbursements, fringe benefits and other special payments. Unless otherwise determined by the administrator prior to the commencement of an offering period, a participant may purchase a maximum of 100,000 shares of common stock during each offering period. In addition, no employee will be permitted to accrue the right to purchase stock under the ESPP at a rate in excess of $25,000 worth of shares during any calendar year during which such a purchase right is outstanding (based on the fair market value per share of our common stock as of the first day of the offering period). After an employee authorizes us to deduct a certain percentage of his or her compensation for the purchase of shares under the ESPP, we will make such deductions from his or her paycheck each pay period during an offering period and hold the accumulated amounts in a bank account until the completion of the offering period. An employee will not receive any interest on the amounts of compensation that we accumulate for the purchase of shares under the ESPP. We may use all funds held by us under the ESPP for any corporate purpose, and we are not obligated to segregate such funds.

In the event of any stock dividend, stock split, combination or exchange of shares, merger, consolidation, spin-off, recapitalization, distribution of company assets to stockholders (other than normal cash dividends), or any other corporate event affecting our common stock, the number of shares reserved under the ESPP and the price per share and number of shares of our common stock covered by each outstanding right may be adjusted proportionately. Such adjustments will be made by the administrator of the ESPP, whose determination in that respect will be final, binding and conclusive.

In the event of certain significant transactions or a change in control (as defined in the ESPP), the administrator of the ESPP may provide for (1) either the replacement or termination of outstanding rights in exchange for cash, (2) the assumption or substitution of outstanding rights by the successor or survivor corporation or parent or subsidiary thereof, if any, (3) the adjustment in the number and type of shares of stock subject to outstanding rights, (4) the use of participants’ accumulated payroll deductions to purchase stock on a new purchase date prior to the next purchase date and termination of any rights under ongoing offering periods or (5) the termination of all outstanding rights.

Transferability. A participant may not transfer rights granted under the ESPP other than by will, the laws of descent and distribution or as otherwise provided under the ESPP.

Amendment and Termination. The administrator of the ESPP may amend, suspend or terminate the ESPP. However, stockholder approval of any amendment to the ESPP will be obtained for any amendment which changes the aggregate number or type of shares that may be sold pursuant to rights under the ESPP, changes the corporations or classes of corporations whose employees are eligible to participate in the ESPP or changes the ESPP in any manner

that would cause the ESPP to no longer be an employee stock purchase plan within the meaning of Section 423(b) of the Code. The ESPP will continue in effect until it is terminated by our board of directors.

The following table sets forth information for the year ended December 31, 2023 regarding the compensation awarded to, earned by or paid to our non-employee directors who served on our board of directors during 2023. Employees of our company who also serve as a director do not receive additional compensation for their performance of services as a director.

The table below shows the aggregate numbers of option awards (exercisable and unexercisable) held as of December 31, 2023 by each non-employee director who was serving as of December 31, 2023.

For the year ended December 31, 2023, each non-employee director received $45,000 for his or her service. Additionally, the chair of our board of directors received an annual cash retainer of $20,000, the chair of the audit committee received an additional annual cash retainer of $15,000, the chair of the compensation committee received an additional annual cash retainer of $8,000, and the chair of the nominating and corporate governance committee received an additional annual cash retainer of $5,500. Audit committee members received an additional cash retainer of $5,750, compensation committee members received an additional annual cash retainer of $4,000 and nominating and corporate governance committee members received an additional annual cash retainer of $2,750.

Each non-employee director who is newly elected or appointed to the board of directors will receive an initial grant of options to purchase 5,833 shares of our common stock, vesting in three equal annual installments on each of the first three anniversaries of the date of grant, upon such election or appointment to the board of directors. Effective January 2023, our board of directors amended the compensation program for our non-employee directors. Under the amended program, non-employee directors receive annual grants of options on the date of each annual meeting of stockholders as follows: each non-employee director, options to purchase 12,000 shares; chair of our board of directors, an additional grant of options to purchase 3,500 shares; chair of the audit committee, an additional grant of options to purchase 3,000 shares; chair of the compensation committee, an additional 2,250 shares; and chair of the nominating and corporate governance committee, an additional grant of options to purchase 1,500 shares. Audit committee members received an additional grant of options to purchase 1,500 shares; members of the compensation committee received an additional grant of 1,125 shares; and the members of the nominating and corporate governance committee received an additional grant of options to purchase 750. All of the annual grants will vest on the first anniversary of the date of grant. The remaining terms of the director compensation program as in effect prior to this amendment remain unchanged.

The following table sets forth certain information regarding the beneficial ownership of the Company’s common stock as of December 31, 2023 by (i) each person or group of persons known by us to beneficially own at least 5% of our common stock, (ii) each of our named executive officers, (iii) each of our directors and (iv) all of our directors and executive officers as a group.

The following table gives effect to the shares of common stock issuable within 60 days of December 31, 2023 upon the exercise of all options and other rights beneficially owned by the indicated stockholders on that date. Beneficial ownership is determined in accordance with Rule 13d-3 promulgated under Section 13 of the Exchange Act and includes voting and investment power with respect to shares. Percentage of beneficial ownership is based on 3,343,070 shares of common stock outstanding on December 31, 2023. Except as otherwise noted below, each person or entity named in the following table has sole voting and investment power with respect to all shares of our common stock that he, she or it beneficially owns.

Unless otherwise indicated below, the address for each beneficial owner listed is c/o Evoke Pharma, Inc., 420 Stevens Avenue, Suite 230, Solana Beach, CA 92075. We believe, based on information provided to us that each of the stockholders listed below has sole voting and investment power with respect to the shares beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable.

The following discussion is a summary of certain material U.S. federal income tax consequences of the purchase, ownership and disposition of the shares of common stock and Pre-Funded Warrants and accompanying Common Warrants or components thereof, which we refer to collectively as the “Securities,” issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or foreign tax laws are not discussed. This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (“IRS”) in effect as of the date of this offering. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a holder of the Securities. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position regarding the tax consequences of the purchase, ownership and disposition of the Securities.

This discussion is limited to holders that hold the Securities as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances, including the impact of the alternative minimum tax or the unearned income Medicare contribution tax. In addition, it does not address consequences relevant to holders subject to particular rules, including, without limitation:

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the Securities, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level.

Accordingly, partnerships holding the Securities and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATION PURPOSES ONLY AND IS NOT INTENDED AS LEGAL OR TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE SECURITIES ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Each share of common stock or Pre-Funded Warrant, as applicable, and accompanying Common Warrants will be treated for U.S. federal income tax purposes as an investment unit consisting of one share of our common stock or Pre-Funded Warrant, as applicable, and accompanying Series A Warrant, Series B Warrant and Series C Warrant. In determining their tax basis for the common stock or Pre-Funded Warrant and the Common Warrants constituting an investment unit, holders of Securities should allocate their purchase price for the investment unit between the common stock or Pre-Funded Warrant, as applicable, and each such Common Warrant on the basis of their relative fair market values at the time of issuance. The Company does not intend to advise holders of the Securities with respect to this determination, and holders of the Securities are advised to consult their tax and financial advisors with respect to the relative fair market values of the common stock or Pre-Funded Warrant, as applicable, and the accompanying Common Warrants for U.S. federal income tax purposes.

Although not free from doubt, a Pre-Funded Warrant should be treated as a share of our common stock for U.S. federal income tax purposes, and a holder of Pre-Funded Warrants should generally be taxed in the same manner as a holder of common stock, as described below. Accordingly, no gain or loss should be recognized (other than with respect to cash paid in lieu of a fractional share) upon the exercise of a Pre-Funded Warrant (except in the case of a cashless exercise, the treatment of which for U.S. federal income tax purposes is not clear) and, upon exercise, the holding period of a Pre-Funded Warrant should carry over to the share of common stock received. Similarly, the tax basis of the Pre-Funded Warrant should carry over to the share of common stock received upon exercise, increased by the exercise price of $0.0001. The discussion below assumes the characterization described above is respected for U.S. federal income tax purposes. Holders should consult their tax advisors regarding the risks associated with the acquisition of Pre-Funded Warrants pursuant to this offering (including alternative characterizations).

For purposes of this discussion, a “U.S. holder” is any beneficial owner of the Securities that, for U.S. federal income tax purposes, is or is treated as any of the following:

As described in the section entitled “Dividend Policy,” we do not expect to pay any cash dividends on our capital stock in the foreseeable future. However, if we do make distributions of cash or property on our common stock or Pre-Funded Warrants (other than certain distributions of common stock), such distributions will constitute dividends to the extent paid out of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes. Dividends received by a corporate U.S. holder may be eligible for a dividends received deduction, subject to applicable limitations. Dividends received by certain non-corporate U.S. holders, including individuals, are generally taxed at the lower applicable capital gains rate provided certain holding period and other requirements are satisfied. Distributions in excess of our current and accumulated earnings and profits will constitute a return of capital and first be applied against and reduce a U.S. holder’s adjusted tax basis in its common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below in the section relating to the sale or disposition of our common stock or Pre-Funded Warrants, as applicable.

Upon the sale, exchange or other taxable disposition of the common stock or Pre-Funded Warrants, a U.S. holder generally will recognize capital gain or loss equal to the difference between (i) the amount of cash and the fair market value of any property received upon the sale, exchange or other taxable disposition and (ii) such U.S. holder’s adjusted tax basis in the common stock or Pre-Funded Warrant. Such capital gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period in such common stock or Pre-Funded Warrant is more than one year at the time of the sale, exchange or other taxable disposition. Long-term capital gains recognized by certain non-corporate U.S. holders, including individuals, generally will be subject to reduced rates of U.S. federal income tax. The deductibility of capital losses is subject to certain limitations.

Upon the sale or other disposition of a Common Warrant (other than by exercise), a U.S. holder will generally recognize capital gain or loss equal to the difference between the amount realized on the sale or other disposition and the U.S. holder’s tax basis in the Common Warrant. This capital gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period in such Common Warrant is more than one year at the time of the sale or other disposition. The deductibility of capital losses is subject to certain limitations.

In general, a U.S. holder will not be required to recognize income, gain or loss upon exercise of a Common Warrant for its exercise price (except to the extent the U.S. holder receives a cash payment for a such fractional share that would otherwise have been issuable upon exercise of the Common Warrant, which will be treated as a sale as described above under “Sale or Other Taxable Disposition of Common Stock or Pre-Funded Warrants”). A U.S. holder’s tax basis in a share of common stock received upon exercise of Common Warrants will be equal to the sum of (i) the U.S. holder’s tax basis in the Common Warrants exchanged therefor and (ii) the exercise price of such Common Warrants. A U.S. holder’s holding period in the shares of common stock received upon exercise will commence on the day after such U.S. holder exercises the Common Warrants. Although there is no direct legal authority as to the U.S. federal income tax treatment of an exercise of a Common Warrant on a cashless basis, we intend to take the position that such exercise will not be taxable, either because the exercise is not a gain realization event or because it qualifies as a tax-free recapitalization. In the former case, the holding period of the shares of common stock received upon exercise of Common Warrants should commence on the day after the Common Warrants are exercised. In the latter case, the holding period of the shares of common stock received upon exercise of Common Warrants would include the holding period of the exercised Common Warrants. However, our position is not binding on the IRS, and the IRS may treat a cashless exercise of a Common Warrant as a taxable exchange. U.S. holders are urged to consult their tax advisors as to the consequences of an exercise of a Common Warrant on a cashless basis, including with respect to their holding period and tax basis in the common stock received.

If a Common Warrant expires without being exercised, a U.S. holder will recognize a capital loss in an amount equal to such holder’s tax basis in the Common Warrant. Such loss will be long-term capital loss if, at the time of the expiration, the U.S. holder’s holding period in such Common Warrant is more than one year. The deductibility of capital losses is subject to certain limitations.

As described in the section entitled “Dividend Policy,” we do not expect to pay any cash dividends on our capital stock in the foreseeable future. However, if, at any time during the period in which a U.S. holder holds Common Warrants or Pre-Funded Warrants, we were to pay a taxable dividend to our stockholders and, in accordance with the anti-dilution provisions of the Common Warrants or Pre-Funded Warrants, the exercise price thereof were decreased, that decrease would be deemed to be the payment of a taxable dividend to a U.S. holder of the Common Warrants or Pre-Funded Warrants, as applicable, to the extent of our earnings and profits, notwithstanding the fact that such holder will not receive a cash payment. If the exercise price is adjusted in certain other circumstances or other adjustments are made (or in certain circumstances, there is a failure to make adjustments), such adjustments may also result in the deemed payment of a taxable dividend to a U.S. holder. In addition, a holder of a Common Warrant or Pre-Funded Warrant may, in some circumstances, be deemed to have received a distribution subject to U.S. federal income tax as a result of an adjustment or the non-occurrence of an adjustment to the exercise price or number of shares of common stock issuable upon exercise of the Common Warrant or Pre-Funded Warrant. U.S. holders should consult their tax advisors regarding the proper treatment of any adjustments to the Common Warrants and Pre-Funded Warrants.

We are currently required to report the amount of any deemed distributions on our website or to the IRS and to holders not exempt from reporting. The IRS has proposed regulations addressing the amount and timing of deemed distributions, as well as obligations of withholding agents and filing and notice obligations of issuers in respect of such deemed distributions. If adopted as proposed, the regulations would generally provide that (i) the amount of a deemed distribution is the excess of the fair market value of the right to acquire stock immediately after the exercise price adjustment over the fair market value of the right to acquire stock (after the exercise price adjustment) without the adjustment, (ii) the deemed distribution occurs at the earlier of the date the adjustment occurs under the terms of the instrument and the date of the distribution of cash or property that results in the deemed distribution and (iii) we are required to report the amount of any deemed distributions on our website or to the IRS and to all holders (including holders that would otherwise be exempt from reporting). The final regulations will be effective for deemed distributions occurring on or after the date of adoption, but holders and withholding agents may rely on them prior to that date under certain circumstances.

A U.S. holder may be subject to information reporting and backup withholding when such holder receives payments on the common stock or Pre-Funded Warrants or Common Warrants (including constructive dividends) or receives proceeds from the sale or other taxable disposition of common stock, Pre-Funded Warrants, or Common Warrants. Certain U.S. holders are exempt from backup withholding, including corporations and certain tax-exempt organizations. A U.S. holder will be subject to backup withholding if such holder is not otherwise exempt and such holder:

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS. U.S. holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of the Securities that is neither a U.S. holder nor an entity treated as a partnership for U.S. federal income tax purposes.

As described in the section entitled “Dividend Policy,” we do not expect to pay any cash dividends on our capital stock in the foreseeable future. However, if we do make distributions of cash or property (other than certain distributions of common stock) on our common stock or Pre-Funded Warrants, such will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a non-U.S. holder’s adjusted tax basis in its common stock or Pre-Funded Warrants, but not below zero. Any excess will be treated as capital gain and will be treated as described below in the section relating to the sale or disposition of our common stock, Pre-Funded Warrants or Common Warrants. Because we may not know the extent to which a distribution is a dividend for U.S. federal income tax purposes at the time it is made, for purposes of the withholding rules discussed below we or the applicable withholding agent may treat the entire distribution as a dividend.

Subject to the discussion below on backup withholding and foreign accounts, dividends paid to a non-U.S. holder of our common stock or Pre-Funded Warrants that are not effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty).

Non-U.S. holders will be entitled to a reduction in or an exemption from withholding on dividends as a result of either (a) an applicable income tax treaty or (b) the non-U.S. holder holding our common stock or Pre-Funded Warrants in connection with the conduct of a trade or business within the United States and dividends being effectively connected with that trade or business. To claim such a reduction in or exemption from withholding, the non-U.S. holder must provide the applicable withholding agent with a properly executed (a) IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) claiming an exemption from or reduction of the withholding tax under the benefit of an income tax treaty between the United States and the country in which the non-U.S. holder resides or is established, or (b) IRS Form W-8ECI stating that the dividends are not subject to withholding tax because they are effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States, as may be applicable. These certifications must be provided to the applicable withholding agent prior to the payment of dividends and must be updated periodically. Non-U.S. holders that do not timely provide the applicable withholding agent with the required certification, but that qualify for a reduced rate under an applicable income tax treaty, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

If dividends paid to a non-U.S. holder are effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such dividends are attributable), then, although exempt from U.S. federal withholding tax (provided the non-U.S. holder provides appropriate certification, as described above), the non-U.S. holder will be subject to U.S. federal income tax on such dividends on a net income basis at the regular U.S. federal income tax rates. In addition, a non-U.S. holder that is a corporation may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits for the taxable year that are attributable to such dividends, as adjusted for certain items. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

A non-U.S. holder generally will not be subject to U.S. federal income tax on the exercise of Common Warrants or Pre-Funded Warrants into shares of common stock. However, if a cashless exercise of Common Warrants or Pre-Funded Warrants results in a taxable exchange, as described in “–Treatment of Pre-Funded Warrants” and “–Tax Considerations Applicable to U.S. Holders – Sale or Other Disposition, Exercise or Expiration of Common Warrants,” the rules described below under “Sale or Other Disposition of Common Stock, Pre-Funded Warrants or Common Warrants” would apply.

Sale or Other Disposition of Common Stock, Pre-Funded Warrants or Common Warrants

Subject to the discussions below on backup withholding and foreign accounts, a non-U.S. holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of our common stock, Pre-Funded Warrants or Common Warrants unless:

Gain described in the first bullet point above will generally be subject to U.S. federal income tax on a net income basis at the regular U.S. federal income tax rates. A non-U.S. holder that is a foreign corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

A non-U.S. holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on any gain derived from the disposition, which may be offset by certain U.S.-source capital losses of the non-U.S. holder (even though the individual is not considered a resident of the United States) provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we believe we are not currently and do not anticipate becoming a USRPHC. Because the determination of whether we are a USRPHC depends on the fair market value of our USRPIs relative to the fair market value of our other business assets and our non-U.S. real property interests, however, there can be no assurance we are not a USRPHC or will not become one in the future.

Non-U.S. holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

As described in the section entitled “Dividend Policy,” we do not expect to pay any cash dividends on our capital stock in the foreseeable future. However, if at any time during the period in which a non-U.S. holder holds Common Warrants or Pre-Funded Warrants we were to pay a taxable dividend to our stockholders and, in accordance with the anti-dilution provisions of the Common Warrants or Pre-Funded Warrants, the exercise price of the warrants were decreased, that decrease would be deemed to be the payment of a taxable dividend to a non-U.S. holder to the extent of our earnings and profits, notwithstanding the fact that such holder will not receive a cash payment. If the exercise price is adjusted in certain other circumstances (or in certain circumstances, there is a failure to make adjustments), such adjustments may also result in the deemed payment of a taxable dividend to a non-U.S. holder. Any resulting withholding tax attributable to deemed dividends may be collected from other amounts payable or distributable to the non-U.S. holder. Non-U.S. holders should consult their tax advisors regarding the proper treatment of any adjustments to the Common Warrants and Pre-Funded Warrants.

Subject to the discussion below on foreign accounts, a non-U.S. holder will not be subject to backup withholding with respect to distributions on our common stock or Pre-Funded Warrants we make to the non-U.S. holder (including constructive dividends with respect to Common Warrants and Pre-Funded Warrants), provided the applicable withholding agent does not have actual knowledge or reason to know such holder is a United States person and the holder certifies its non-U.S. status, such as by providing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or other applicable certification. However, information returns generally will be filed with the IRS in connection with any distributions (including deemed distributions) made on our common stock, Pre-Funded Warrants and Common

Warrants to the non-U.S. holder, regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the non-U.S. holder resides or is established.

Information reporting and backup withholding may apply to the proceeds of a sale or other taxable disposition of our common stock, Pre-Funded Warrants or Common Warrants within the United States, and information reporting may (although backup withholding generally will not) apply to the proceeds of a sale or other taxable disposition of our common stock, Pre-Funded Warrants or Common Warrants outside the United States conducted through certain U.S.-related financial intermediaries, in each case, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder on IRS Form W-8BEN or W-8BEN-E, or other applicable form (and the payor does not have actual knowledge or reason to know that the beneficial owner is a U.S. person), or such owner otherwise establishes an exemption. Proceeds of a disposition of our common stock, Pre-Funded Warrants or Common Warrants conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act (“FATCA”)) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends (including deemed dividends) paid on our common stock, Pre-Funded Warrants or Common Warrants, or (subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of our common stock, Pre-Funded Warrants or Common Warrants paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements clause in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States-owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends (including deemed dividends). Because we may not know the extent to which a distribution is a dividend for U.S. federal income tax purposes at the time it is made, for purposes of these withholding rules we or the applicable withholding agent may treat the entire distribution as a dividend. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of our common stock, Pre-Funded Warrants or Common Warrants on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

Prospective investors should consult their tax advisors regarding the potential application of these withholding provisions.

We have entered into an underwriting agreement with Craig-Hallum Capital Group LLC and Laidlaw & Company (UK) Ltd. (the “Representatives”), as the representatives of the underwriters named below and the book-running managers of this offering. Subject to the terms and conditions of an underwriting agreement between us and the Representative, we have agreed to sell to the underwriters, and the underwriters have agreed to purchase, at the public offering price less the underwriting discounts set forth on the cover page of this prospectus, the number of our securities listed next to its name in the following table:

The underwriters are committed to purchase all of the securities offered by us if it purchases any securities. The obligations of the underwriters may be terminated upon the occurrence of certain events specified in the underwriting agreement. Furthermore, pursuant to the underwriting agreement, the underwriters’ obligations are subject to customary conditions, representations, and warranties contained in the underwriting agreement, such as receipt by the underwriters of officers’ certificates and legal opinions.

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

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

The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters.

(1) Reflects underwriting discounts and commissions to the underwriters of $599,953, or eight percent (8%) per share. We have also agreed to issue the Representatives of the underwriters or their designees warrants to purchase up to 551,471 shares of Common Stock, equal to 5% of the securities sold in this offering, to pay the warrant solicitation fee described below, and to reimburse the underwriters for certain offering expenses. In addition, we have agreed to pay a management fee to the Representatives equal to 0.75% of the gross proceeds received in this offering, which is not included in the underwriting discounts and commissions.

The underwriters propose to offer the securities offered by us to the public at the public offering price set forth on the cover of this prospectus. In addition, the underwriters may offer some of the securities to other securities dealers at such price less an expected concession of $0.03264. If all of the shares offered by us are not sold at the public offering price, the Representatives may change the offering price and other selling terms by means of a supplement to this prospectus.

We have also agreed to reimburse the underwriters for their expenses in connection with this offering, up to $125,000, including fees of underwriters' counsel. We estimate that the total expenses of the offering payable by us, excluding the total underwriting discount and reimbursement of fees of underwriters' counsel, will be approximately $600,000.

Upon any exercise of the Series B Warrants issued in this offering, we have agreed to pay the underwriters a cash fee equal to 5.0% of the aggregate gross proceeds received upon the exercise of the Series B Warrants in accordance with the Financial Industry Regulatory Authority (“FINRA”) Rule 5110(g)(10).

The underwriters do not intend to confirm sales of the securities offered hereby to any accounts over which they have discretionary authority.

Upon the closing of this offering, we have agreed to issue to the Representatives or their designees warrants to purchase 551,471 of Common Stock, equal to five percent (5%) of the aggregate number of Units sold in this offering (the “Representatives’ Warrants”). The Representatives’ Warrants will be exercisable six months from the effective date of this registration statement and will expire five years from the effective date thereof. The exercise price of the warrants is $1.220 per share, equal to 165% of the offering price of the price per Units offered hereby. The Representatives' Warrants have been deemed compensation by FINRA and are therefore subject to a 180-day lock-up pursuant to Rule 5110(e) of FINRA. The Representatives (or permitted assignees under Rule 5110(e)) will not sell, transfer, assign, pledge, or hypothecate these warrants or the securities underlying these warrants, nor will they engage in any hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of the warrants or the underlying securities for a period of 180 days from the effective date of the offering. In addition, the warrants provide for registration rights upon request, in certain cases. The one-time demand registration right provided will not be greater than five years from the effective date of the registration statement in compliance with FINRA Rule 5110(g)(8)(C). The unlimited piggyback registration right provided will not be greater than seven years from the effective date of the registration statement in compliance with FINRA Rule 5110(g)(8)(D). We will bear all fees and expenses attendant to registering the securities issuable on exercise of the warrants other than underwriting commissions incurred and payable by the holders.

Our executive officers and directors have agreed with the Representatives to be subject to a lock-up period of 90 days following the date of closing of the offering pursuant to this prospectus. This means that, during the lock-up period, such persons may not offer for sale, contract to sell, sell, distribute, grant any option, right or warrant to purchase, pledge, hypothecate or otherwise dispose of, directly or indirectly, any shares of our common stock or any securities convertible into, or exercisable or exchangeable for, shares of our Common Stock, subject to certain customary exceptions. The Representatives may, in their sole discretion and without notice, waive the terms of any of these lock-up agreements. We have also agreed, in the underwriting agreement, that without prior written notice to the Representatives, we will not offer, sell, issue or otherwise transfer or dispose of our securities for 90 days following the closing of this offering, subject to certain customary exceptions.

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

In connection with this offering, each underwriter may engage in transactions that stabilize, maintain, or otherwise affect the price of our securities. Specifically, such underwriter may over-allot in connection with this offering by selling more securities than are set forth on the cover page of this prospectus. This creates a short position in our

securities for such underwriter’s own accounts. The short position may be either a covered short position or a naked short position. In a covered short position, the number of securities over-allotted by such underwriter is not greater than the number of securities that it may purchase in the over-allotment option. In a naked short position, the number of securities involved is greater than the number of securities in the over-allotment option. To close out a short position, such underwriter may elect to exercise all or part of the over-allotment option. Such underwriter may also elect to stabilize the price of our securities or reduce any short position by bidding for, and purchasing, securities in the open market.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter or dealer repays selling concessions allowed to it for distributing a security in this offering because the underwriter repurchases that security in stabilizing or short covering transactions.

Finally, each underwriter may bid for, and purchase, shares of our securities in market-making transactions, including “passive” market-making transactions as described below.

These activities may stabilize or maintain the market price of our securities at a price that is higher than the price that might otherwise exist in the absence of these activities. The underwriters are not required to engage in these activities and may discontinue any of these activities at any time without notice. These transactions may be affected on NASDAQ, in the over-the-counter market, or otherwise.

In connection with this offering, the underwriters and selling group members, if any, or their affiliates may engage in passive market-making transactions in our Common Stock immediately prior to the commencement of sales in this offering, in accordance with Rule 103 of Regulation M under the Exchange Act. Rule 103 generally provides that:
