Common Stock
We have entered into an open market sales agreement, the Sales Agreement, with SVB Leerink LLC, or SVB Leerink, relating to the sale of shares of our common stock offered by this prospectus supplement. In accordance with the terms of the Sales Agreement, we may offer and sell shares of our common stock, $0.0001 par value per share, having an aggregate offering price of up to $30 million from time to time through or to SVB Leerink, acting as our agent.
Our common stock is listed on the Nasdaq Capital Market under the symbol “EYEN”. On May 10, 2021, the last reported sale price of our common stock on the Nasdaq Capital Market was $4.63 per share.
Sales of the common stock, if any, under this prospectus supplement may be made in sales deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, or the Securities Act. SVB Leerink is not required to sell any specific amount of securities, but will act as our sales agent using commercially reasonable efforts consistent with its normal trading and sales practices, on mutually agreed terms between SVB Leerink and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.
The compensation to SVB Leerink for sales of our common stock will be 3.0% of the gross sales price per share sold. See “Plan of Distribution” beginning on page S-13 for additional information regarding the compensation to be paid to SVB Leerink. In connection with the sale of the common shares on our behalf, SVB Leerink will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of SVB Leerink will be deemed to be underwriting commissions. We have also agreed to provide indemnification and contribution to SVB Leerink with respect to certain liabilities, including liabilities under the Securities Act.
We are an “emerging growth company” under the federal securities laws and, as such, we are subject to reduced public company disclosure standards.
INVESTING IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD REVIEW CAREFULLY THE RISKS AND UNCERTAINTIES DESCRIBED UNDER THE HEADING “RISK FACTORS” ON PAGE S-6 OF THIS PROSPECTUS, AND UNDER SIMILAR HEADINGS IN THE DOCUMENTS THAT ARE INCORPORATED BY REFERENCE INTO THIS PROSPECTUS.
Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus are truthful or complete. Any representation to the contrary is a criminal offense.

PROSPECTUS SUPPLEMENT SUMMARY
This summary highlights information contained elsewhere in this prospectus supplement, or incorporated by reference into this prospectus supplement and the accompanying prospectus. It might not contain all the information that is important to you. You should carefully read the entire prospectus supplement, the accompanying prospectus, any applicable additional prospectus supplement or free writing prospectus we file with the SEC and the information incorporated herein by reference, including the financial data and related notes and the sections entitled “Risk Factors”.
Our Business
We are a clinical stage ophthalmic company developing a pipeline of advanced therapeutics based on our proprietary microdose array print (MAP™) platform technology. We aim to achieve clinical microdosing of next-generation formulations of novel and existing ophthalmic pharmaceutical agents using our high-precision targeted ocular delivery system, branded the Optejet®. Optejet µ-therapeutics have the potential to replace conventional eye dropper delivery and improve safety, tolerability, patient compliance and topical delivery success for ophthalmic eye treatments. In the clinical trials, the Optejet has demonstrated that our targeted horizontal microdose delivery can achieve a significantly higher rate of successful ocular topical delivery compared to the established rate reported with traditional eye drops (~ 90% vs. ~ 50%). Our technology is designed to achieve single-digit µl-volume physiologic drug delivery with up to a 75% reduction in ocular drug and preservative topical dosing and has demonstrated significant improvement in the therapeutic index in drugs used for mydriasis and intraocular pressure lowering through three Phase II and Phase III trials. Conventional eye formulations lack high-precision micro-volume delivery and expose the ocular surface to approximately 300% more medication and preservatives than are physiologically indicated leading to clinically recognized ocular and non-ocular side effects. Using the Optejet, we are developing the next generation of smart ophthalmic therapeutics which target new indications or new combinations where there are currently no comparable drug therapies approved by the U.S. Food and Drug Administration (the “FDA”). Our microdose therapeutics follow the FDA-designated pharmaceutical registration and regulatory process. Our products are classified by the FDA as drugs, and not medical devices or drug-device combination products.
Our pipeline is currently focused on the late-stage development of novel, potential first-in-class therapeutic indications for an estimated over five million potential patients with progressive myopia in the United States and estimated over one hundred million potential patients with age-related near vision impairment, or presbyopia — indications where there is tremendous unmet need and no known existing FDA-approved therapies. We are also developing the first microdose fixed combination ophthalmic pharmaceutical for mydriasis to address the estimated over 100 million annual comprehensive eye exams with pupil dilation.
Corporate Information
We were organized as a corporation under the laws of the State of Florida on March 12, 2014 under the name “PGP Holdings V, Inc.” On May 5, 2014, we changed our name to Eyenovia, Inc. On October 6, 2014, we reincorporated in the State of Delaware by merging into Eyenovia, Inc., a Delaware corporation. Our principal executive office is located at 295 Madison Avenue, Suite 2400, New York, NY 10017, and our phone number is 917-289-1117. Our website is http://www.eyenovia.com. The reference to our website is an inactive textual reference only and information contained in, or that can be assessed through, our website is not incorporated by reference into this prospectus and does not constitute a part of this prospectus.
Implications of Being an Emerging Growth Company
As a company with less than $1.0 billion in revenue during our last fiscal year, we qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). For so long as we remain an emerging growth company, we are permitted and intend to rely on exemptions from specified disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include:
 
S-3

TABLE OF CONTENTS
 

being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;

not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting;

not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;

reduced disclosure obligations regarding executive compensation; and

exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.
We may take advantage of these provisions through 2023 or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company if we have more than $1.07 billion in annual revenues, have more than $700 million in market value of our capital stock held by non-affiliates, or issue more than $1.0 billion of non-convertible debt over a three-year period. We may choose to take advantage of some, but not all, of the available exemptions. We have taken advantage of some reduced reporting burdens in this prospectus and the documents incorporated by reference into this prospectus. Accordingly, the information contained herein may be different than the information you receive from other public companies in which you hold stock.
In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This provision allows an emerging growth company to delay the adoption of some accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of this exemption from new or revised accounting standards and, therefore, will not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

RISK FACTORS
Investing in our securities involves a high degree of risk. You should consider carefully the risks and uncertainties, as well as other information, in this prospectus supplement and the accompanying prospectus, including the risks described under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020 which is incorporated herein by reference, and as updated by any other document that we subsequently file with the SEC and that is incorporated by reference into this prospectus supplement and the accompanying prospectus, and any free writing prospectus that we have authorized for use in connection with this offering. The risks set forth in this prospectus supplement and incorporated herein by reference are those which we believe are the material risks that we face. These risks are not the only ones facing us and there may be additional matters that we are unaware of or that we currently consider immaterial. The occurrence of any of such risks may materially and adversely affect our business, financial condition, results of operations and future prospects. In such an event, the market price of our common stock could decline, and you could lose part or all of your investment.
RISKS RELATED TO THIS OFFERING
You may experience immediate and substantial dilution.
The offering price per share being offered may exceed the net tangible book value per share of our common stock outstanding prior to this offering. Assuming that an aggregate of 6,479,482 shares of our common stock are sold during the term of the Sales Agreement with SVB Leerink at a price of $4.63 per share, the last reported sale price of our common stock on the Nasdaq Capital Market on May 10, 2021, for aggregate gross proceeds of $28.9 million, after deducting commissions and estimated aggregate offering expenses payable by us, you will experience immediate dilution of $3.35 per share, representing the difference between our as-adjusted net tangible book value per share as of March 31, 2021, after giving effect to this offering and the assumed offering price. The exercise of outstanding stock options and warrants may result in further dilution of your investment. See the section entitled “Dilution” below for a more detailed illustration of the dilution you would incur if you participate in this offering.
We may be required to raise additional capital by issuing new securities with terms or rights superior to those of our existing securityholders, which could adversely affect your investment in our company, the market price of shares of our common stock and our business.
We might require additional financing to fund future operations, including our research and development, manufacturing and any possible sales and marketing activities. We may not be able to obtain financing on favorable terms, if at all. If we raise additional funds by issuing equity securities, the percentage ownership of our then current stockholders will be reduced, and the holders of the new equity securities may have rights superior to those of our then existing securityholders, which could adversely affect the market price of our common stock and the voting power of shares of our common stock. If we raise additional funds by issuing debt securities, the holders of these debt securities would similarly have some rights senior to those of our then existing securityholders, and the terms of these debt securities could impose restrictions on operations and create a significant interest expense for us which could have a materially adverse effect on our business.
Sales of our common stock in this offering, or the perception that such sales may occur, could cause the market price of our common stock to fall.
We may issue and sell shares of our common stock for aggregate gross proceeds of up to $30 million from time to time in connection with this offering. The actual number of shares of common stock that may be issued and sold in this offering, as well as the timing of any such sales, will depend on a number of factors, including, among others, the prices at which any shares are actually sold in this offering (which may be influenced by market conditions, the trading price of our common stock and other factors) and our determinations as to the appropriate timing, sources and amounts of funding we need. The issuance and sale from time to time of these new shares of common stock, or the mere fact that we are able to issue and sell these shares in this offering, could cause the market price of our common stock to decline.

TABLE OF CONTENTS
 
It is not possible to predict the actual number of shares of common stock we will sell under the Sales Agreement, or the gross proceeds resulting from those sales.
Subject to certain limitations in the Sales Agreement and compliance with applicable law, we have the discretion to deliver a placement notice to SVB Leerink at any time throughout the term of the Sales Agreement. The number of shares that are sold through SVB Leerink after the delivery of a placement notice will fluctuate based on a number of factors, including the market price of our common stock during the sales period, the limits we set with SVB Leerink in any applicable placement notice, and the demand for our common stock during the sales period. Because the price per share will fluctuate during this offering, it is not currently possible to predict the number of shares that will be sold or the gross proceeds to be raised in connection with those sales.
The common stock offered hereby will be sold in “at-the-market offerings” and investors who buy shares at different times will likely pay different prices.
Investors who purchase shares in this offering at different times will likely pay different prices, and accordingly may experience different levels of dilution and different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices and number of shares sold in this offering. Investors may experience a decline in the value of the shares they purchase in this offering as a result of sales made at prices lower than the prices they paid.
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 the net proceeds from this offering and could spend the proceeds in ways that do not improve our business, financial condition or results of operations or enhance the value of our common stock. See “Use of Proceeds” on page S-10 of this prospectus supplement for a description of our proposed use of proceeds from this offering.
The failure by our management to apply these funds effectively could result in financial losses that could harm our business, cause the price of our common stock to decline and delay the development of our product candidates. Pending their use, we may invest the net proceeds from this offering in a manner that does not produce income or that loses value.
We might not be able to continue as a going concern which would likely cause our stockholders to lose most or all of their investment.
Our audited financial statements for the year ended December 31, 2020 and our unaudited financial statements for the quarter ended March 31, 2021 were prepared under the assumption that we would continue as a going concern. However, our independent registered public accounting firm included a “going concern” explanatory paragraph in its report on our financial statements for the year ended December 31, 2020, indicating that, without additional sources of funding, our cash at December 31, 2020 is not sufficient for us to operate as a going concern for a period of at least one year from the date that the financial statements included in our Annual Report on Form 10-K are issued. Management’s plans concerning these matters, including our need to raise additional capital, are described in Note 2 — Summary of Significant Accounting Policies — Liquidity and Going Concern of our financial statements included within our Annual Report on Form 10-K for the year ended December 31, 2020 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2021, however, management cannot assure you that its plans will be successful. In light of the foregoing, there is substantial doubt about our ability to continue as a going concern. If we cannot continue as a viable entity, our stockholders would likely lose most or all of their investment in us.

changes in U.S. GAAP; and

changes in the legal, regulatory and legislative environments in the markets in which we operate, and the impact of these changes on our ability to obtain regulatory approval for our products.
Although we believe that our expectations (including those on which our forward-looking statements are based) are reasonable, we cannot assure you that those expectations will prove to be correct. Should any one or more of these risks or uncertainties materialize, or should any underlying assumptions prove incorrect, actual results may vary materially from those described in our forward-looking statements as anticipated, believed, estimated, expected or intended.

USE OF PROCEEDS
We may issue and sell up to $30 million of our common stock from time to time. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. There can be no assurance that we will sell any shares under or fully utilize the Sales Agreement with SVB Leerink as a source of financing.
We intend to use the net proceeds from this offering, if any, for working capital and general corporate purposes.
As of the date of this prospectus, we cannot specify with certainty any of the particular uses of the proceeds, if any, from this offering. Accordingly, we will retain broad discretion over the use of any such proceeds. Pending the use of the net proceeds, if any, from this offering as described above, we intend to invest the net proceeds in investment-grade, interest-bearing instruments.

DILUTION
Dilution to purchasers in this offering represents the difference between the amount per share of common stock paid by purchasers of shares of common stock in this offering and the as adjusted net tangible book value per share of our common stock immediately after this offering. The data in this section are derived from our balance sheet as of March 31, 2021. Net tangible book value per share of common stock is equal to our total tangible assets less the amount of our total liabilities, divided by the sum of the number of shares of common stock outstanding as of March 31, 2021. Our net tangible book value as of March 31, 2021 was $12.1 million, or $0.47 per share of common stock.
We present dilution on an as adjusted basis to give effect to the sale by us of shares of our common stock in this offering in the aggregate amount of $30.0 million, at an assumed public offering price of $4.63 per share of common stock, the last reported sale price of our common stock on The Nasdaq Capital Market on May 10, 2021, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us. Our as adjusted net tangible book value as of March 31, 2021 would have been $41.1 million, or $1.28 per share of common stock. This represents an immediate increase in net tangible book value to existing stockholders of $0.81 per share of common stock and immediate dilution in net tangible book value to purchasers of shares of common stock in this offering of $3.35 per share of common stock. The following table illustrates this dilution per share of common stock:

The above discussion and tables are based on 25,623,577 shares of our common stock outstanding as of March 31, 2021 and excludes:

3,429,342 shares of our common stock underlying outstanding options to purchase common stock under our 2014 Plan and our 2018 Plan with a weighted average exercise price of  $3.37 per share;

105,306 shares of our common stock issuable in connection with restricted stock units under our 2014 Plan and 2018 Plan;

515,326 shares of our common stock reserved for future issuance under our 2014 Plan and 2018 Plan; and

warrants for 1,366,321 shares of our common stock, with a weighted average exercise price of $2.51 per share.
To the extent that any of these options or warrants are exercised, new options are issued under our 2018 Plan or we issue additional shares of common stock, warrants or other equity securities in the future, there may be further dilution to investors participating in this offering.
The table above assumes for illustrative purposes that an aggregate of 6,479,482 shares of our common stock are sold during the term of the Sales Agreement with the agent at a price of $4.63 per share, the last reported sale price of our common stock on the Nasdaq Capital Market on May 10, 2021, for aggregate gross proceeds of $30 million. The shares sold in this offering, if any, will be sold from time to time at various prices. An increase of $0.25 per share in the price at which the shares are sold from the assumed offering price of $4.63 per share, assuming all of our common stock in the aggregate amount of $30 million during the term of the Sales Agreement with the agent is sold at that price, would increase our adjusted net tangible book value per share after the offering to $1.29 per share and would increase the dilution in net tangible book value per share to new investors in this offering to $3.59 per share, after deducting commissions and estimated offering expenses payable by us. A decrease of $0.25 per share in the price at which the shares are sold from the assumed offering price of $4.63 per share, assuming all of our common stock in the aggregate amount of $30 million is sold at that price, would decrease our adjusted net tangible book value per share after the offering to $1.26 per share and would decrease the dilution in net tangible book value per share to

new investors in this offering to $3.12 per share, after deducting commissions and estimated offering expenses payable by us. This information is supplied for illustrative purposes only.
We may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities may result in further dilution to our shareholders. To the extent that outstanding options or warrants outstanding as of March 31, 2021 have been or may be exercised or other shares issued, investors purchasing our common stock in this offering may experience further dilution.

PLAN OF DISTRIBUTION
We have entered into a Sales Agreement with SVB Leerink under which we may issue and sell shares of common stock having an aggregate offering price of up to $30 million from time to time through SVB Leerink as our sales agent. Sales of shares of common stock, if any, under this prospectus will be made at market prices by any method that is deemed to be an “at-the-market” offering, as defined in Rule 415 under the Securities Act, including sales made directly on the Nasdaq Capital Market or any other trading market for our common stock. If authorized by us in writing, SVB Leerink may purchase shares of our common stock as principal.
SVB Leerink will offer shares of our common stock subject to the terms and conditions of the Sales Agreement on a daily basis or as otherwise agreed upon by us and SVB Leerink. We will designate the maximum amount of common stock to be sold through SVB Leerink on a daily basis or otherwise determine such maximum amount together with SVB Leerink. Subject to the terms and conditions of the Sales Agreement, SVB Leerink will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell on our behalf all of the shares of common stock requested to be sold by us. We may instruct SVB Leerink not to sell shares of common stock if the sales cannot be effected at or above the price designated by us in any such instruction. SVB Leerink or we may suspend the offering of shares of our common stock being made through SVB Leerink under the Sales Agreement upon proper notice to the other party. SVB Leerink and we each have the right, by giving written notice as specified in the Sales Agreement, to terminate the Sales Agreement in each party’s sole discretion at any time. The offering of shares of our common stock pursuant to the Sales Agreement will otherwise terminate upon the termination of the Sales Agreement as provided therein.
The aggregate compensation payable to SVB Leerink as sales agent will be an amount equal to 3.0% of the gross proceeds of any shares sold through it pursuant to the Sales Agreement. We have also agreed to reimburse SVB Leerink up to $75,000 of SVB Leerink’s actual outside legal expenses incurred by SVB Leerink in connection with this offering. We have also agreed to reimburse SVB Leerink for certain ongoing fees of its legal counsel.

Our Business
Overview
We are a clinical stage ophthalmic biopharmaceutical company developing a pipeline of microdose therapeutics utilizing our patented piezo-print delivery technology, which we recently branded the Optejet™. Eyenovia aims to achieve clinical microdosing of next-generation formulations of well-established ophthalmic pharmaceutical agents using its high-precision targeted ocular delivery system, which has the potential to replace conventional eyedropper delivery and improve safety, tolerability, patient compliance and topical delivery success for ophthalmic eye treatments. In the clinic, Optejet has demonstrated up to a 75% reduction in ocular drug and preservative exposure, with successful topical delivery that generally exceeded the efficacy of traditional eyedrop administration. Using our proprietary delivery technology, Eyenovia is developing the next generation of smart ophthalmic therapies while targeting new indications for which there are currently no drug therapies approved by the U.S. Food and Drug Administration (the “FDA”). Eyenovia’s microdose therapeutics follow the FDA-designated pharmaceutical registration and regulatory process. Our products are not classified by the FDA as medical devices or drug-device combination products.
Eyenovia recently initiated Phase III trials for MicroStat. MicroStat is a fixed combination formulation of phenylephrine-tropicamide for mydriasis (pupil dilation), designed to be a novel approach for the estimated 80 million office-based comprehensive and diabetic eye exams performed every year in the United States. Additionally, we have received clear feedback from the FDA regarding the requirements for Phase III trials for our MicroPine and MicroProst programs. MicroPine is a first-in-class topical therapy for the treatment of progressive myopia, a back-of-the-eye ocular disease associated with pathologic axial elongation and sclero-retinal stretching affecting approximately 5 million people in the United States. MicroProst is a novel latanoprost formulation for lowering intraocular pressure (“IOP”) in patients with ocular hypertension (“OHT”), primary open angle glaucoma (“POAG”) and chronic angle closure glaucoma (“CACG”). MicroTears, our over-the-counter (“OTC”) product candidate for dry eye, will not require Phase III trials. We plan to proceed with registration activities for MicroTears this year.
We have completed three Phase II trials, with results from two published in peer-reviewed literature and a third in press publication. In two studies evaluating mydriatic agents, the Optejet consistently delivered precision dosing at the volume of the eye’s natural tear film capacity of 6 – 8 µL, which reduced ocular and systemic drug and preservative exposure, while demonstrating pupil dilation comparable to conventional eyedrops with fewer side effects. In the third study, we evaluated usability, patient tolerability and intraocular pressure lowering of microdosed latanoprost administered with the Optejet. In this study, eyes receiving microdosed latanoprost achieved IOP reduction consistent with published literature on eyedrops and administration of the medication was successful in a single attempt in more than 90% of cases. Based on the results from these clinical trials, we have advanced MicroStat into Phase III utilizing the 505(b)(2) pathway and plan to do the same with MicroPine and MicroProst. Where possible, we also intend to use this pathway for future clinical trials in new indications with significant unmet needs.
Our Solution
Ophthalmic drugs delivered as eyedrops can fail to provide the prescribed dose more than 50% of the time and, even when the prescribed dose is delivered to the ocular surface, eyedrops can overdose the ocular surface by more than 300%. The average tear volume of the eye is 6 – 8 µL, yet conventional eyedrops deliver fluid volume of approximately 30 – 50 µL. Even among bottles of the same size and shape, eyedrop sizes vary significantly depending on the angle of the bottle and the amount of ophthalmic solution remaining. The large drop size can result in overflow from the eye into the nasolacrimal canal, where the active drug product becomes available systemically. Ocular drugs that are absorbed by the nasolacrimal mucosa mimic

intravenous injection delivery insofar as they are not susceptible to first-pass hepatic metabolism. Additionally, ocular medication in swallowed nasolacrimal secretions is theoretically available for absorption in the gastrointestinal tract. As such, only a small fraction of the applied medication is actually absorbed directly into the eye, while there remain multiple opportunities for unintended local and systemic exposure. Additionally, excess drug (and preservative in some instances) in the eye is more likely to cause ocular surface toxicity and tolerability issues and spillage to the periorbital skin can cause dermatological changes.
Instillation of eyedrops also stimulates lacrimation, and can increase tear turnover rate from 16% per minute to 30% per minute once eyedrops have been instilled, thereby diluting the drug product. If the eyedrop stings, the loss rate can be even higher. Approximately 80% of a medication instilled as an eyedrop is lost to drainage during the first 15 – 30 seconds after instillation.
The Optejet
[MISSING IMAGE: tv524860_img-optejet1.jpg]
[MISSING IMAGE: tv524860_img-optejet2.jpg]
The Optejet delivers doses of 6 – 8 µL, directly coating the corneal surface where 80% of intraocular drug penetration occurs. We believe that microdosing may reduce drug and toxic preservative exposure by more than 75%, thus reducing ocular irritation, and resulting in potentially gentler treatments without compromising the desired clinical effect. Our approach could also reduce waste associated with conventional macrodose drops — a problem that has been highlighted by recently introduced legislation in the U.S. Senate to address this specific concern.
We believe that we are one of the only companies with clinical stage technology for targeted microdosing of ophthalmic investigational therapies. The Optejet is based on piezo-print technology, which is also used for pixel-sharp high-precision inkjet printing. The technology is optimized for and applied in ophthalmic delivery to achieve microdosing that can be many times more precise than conventional eyedroppers. In addition, our smart, electronic system provides the capability to track when patients administer their

medications and deliver this information to patients and physicians via Bluetooth connectivity. Thus, physicians can make decisions regarding therapeutic regimens with knowledge of patient compliance.
The FDA has provided written feedback that our clinical development activities will be treated as drug development programs, because only the drug comes into contact with the eye. Consequently, we do not anticipate needing separate FDA approval for the Optejet or being required to comply with FDA medical device regulations.
Microdose administration of topical ophthalmic drugs with the Optejet has been tested in preclinical models and clinical trials and shown to provide many advantages over administrations of eyedrops. Key advantages include:

Dose reduction:   Our microdose delivery technology achieves precise volumetric control at the microliter level to deliver 6 – 8 µL, which is the physiologic capacity of the tear film. This compares favorably to the volume of an eyedrop (30 – 50 µL), which can result in overdosing, ocular toxicity and systemic leaching into the plasma.

Targeted dose instillation:   The Optejet allows for targeted delivery to the ocular surface and cornea, avoiding the conjunctival cul-de-sac. The micro-jet spray created by the piezo-electric vibrations is columnated and focused to provide precise delivery to the corneal surface where the majority of ocular penetration occurs. Additionally, the Optejet is designed with an LED targeting mechanism to facilitate proper positioning and objective alignment, thus increasing the likelihood of successful dose delivery.

Speed of delivery:   Our piezo-electric technology is similar to pixel-sharp precision ink jet printing. Unlike a simple aerosolized mechanism, our patented technology is designed with ejection control that creates a fast and targeted micro-jet delivery. Solution is delivered to the ocular surface in less than 80 milliseconds beating the typical eye’s 100-millisecond blink reflex.

Smart electronics:   Our smart electronics and mobile e-health technology are designed to track when a patient administers treatment. This enables physicians to objectively monitor patient compliance. We believe this technology will improve compliance and chronic disease management by empowering patients and physicians with access to dynamic, real-time monitoring and compliance data for a more intelligent and personalized therapeutic paradigm.

Our fixed combination product has been developed to help achieve efficient pupil dilation while reducing unintended effects of conventionally administered mydriatic agents. We believe the market exceeds $150 million annually in the United States alone.
Phase III Clinical Development Program
Our New Drug Application (“NDA”) has been accepted by the FDA and we initiated Phase III clinical trials of fixed-combination microdosed phenylephrine 2.5% and tropicamide 1% administered for mydriasis in November 2018.

TABLE OF CONTENTS
 
The MicroStat program consists of two Phase III randomized, controlled, cross-over clinical studies evaluating pupil dilation with our fixed combination product in comparison with the individual drug components (phenylephrine 2.5% and tropicamide 1%, respectively), and with a placebo. The primary endpoint for each study is the mean change in pupil diameter at 35 minutes post-drug administration. If the primary objectives of our Phase III program are met, we plan to submit an NDA to the FDA for marketing approval in the United States. Outside of the United States, we have entered into a licensing partnership for MicroStat with one of our largest stockholders and a leading ophthalmology company in Japan, Senju Pharmaceuticals, Co. Ltd. (“Senju Pharmaceuticals”), for commercialization in Asia, including China, Japan and India.
MicroPine
A key therapeutic program for Eyenovia is our first-in-class topical treatment for progressive myopia, a back-of-the-eye disease. Progressive myopia is estimated to affect close to 5 million patients in the United States who suffer from uncontrolled axial elongation of the sclera leading to increasing levels of myopia and in some cases major pathologic changes such as retinal atrophy, macular staphylomas, retinal detachment and visual impairment.

Academic groups have demonstrated that high efficacy with low dose atropine reduces myopia progression 60 – 70%, with sustained effect through three years. A recent therapeutic evidence assessment and review by the American Academy of Ophthalmology, indicates Level 1 (highest) evidence of efficacy for the role of low dose atropine for progressive myopia (Ophthalmology 2017;124:1857-1866; Ophthalmology 2016; 123(2) 391:399). While atropine 1% ophthalmic solution is commercially available, we believe the significant side effects associated with its use in the pediatric population make its use undesirable for the treatment of progressive myopia.

Phase III Clinical Development Program
MicroPine is Eyenovia’s clinical development program involving the formulation and the Optejet microdose administration of low-dose atropine for reduction of progressive myopia. Based on FDA feedback, we anticipate initiation of the single required Phase III trial enrolling children and adolescents who will use MicroPine therapy daily. The primary assessment of efficacy is based on reduction in myopia progression at three years, at which point the data will be analyzed and submitted in an NDA for FDA review, with a follow-up in the fourth year required to assess any rebound effects associated with a change in the medication regimen.
MicroProst
MicroProst is our proprietary latanoprost formulation product candidate, which we are developing as a first-line treatment for reduction of IOP in patients with OHT, POAG and CACG. Currently, there are no FDA-approved therapies for CACG, even though it accounts for an estimated 10% and 50% of all glaucoma diagnoses in the United States and China, respectively. We believe that the market for MicroProst exceeds $700 million annually in the United States alone.
Phase III Clinical Development Program
Subsequent to the completion of early phase clinical trials, we met with the FDA to discuss our Phase III plans for MicroProst. The FDA outlined the necessary clinical trials for approval and we are preparing to initiate a Phase III registration program for MicroProst relying on the 505(b)(2) pathway in the first half of 2019. If approved, we believe MicroProst could have the widest indication of commercially available IOP-lowering therapies, including the first FDA-approved treatment for CACG. Based on the results of our earlier study of Optejet-administered latanoprost (PG-21), we believe MicroProst will achieve similar clinical efficacy without the adverse effects seen with conventional drops, which overdose the eye with potentially harmful preservatives and active pharmaceutical ingredient.
We anticipate that the MicroProst clinical program will require a single Phase III randomized controlled clinical trial involving patients with OHT, POAG and/or CACG, with a three-month primary endpoint evaluating IOP reduction and follow-up through six months for safety. We plan to begin the clinical trial for MicroProst in the first half of 2019. We have entered into a licensing partnership for our MicroProst program with Senju Pharmaceuticals for Asia, including China where CACG accounts for up to 50% of all glaucoma.
MicroTears
MicroTears is a micro-droplet ocular surface tear replenishment product candidate for the estimated $2 billion-plus (200 million units) annual OTC artificial tear market. The Optejet can enable accurate delivery

of MicroTears directly to the ocular surface, which we believe will enhance its effectiveness. The lower volume of MicroTears could also lower the incidents of droplet overflow. While no FDA studies are required for registration of a monograph formulation, we expect to conduct multiple Phase IV post-marketing studies to demonstrate the benefits of MicroTears. We plan to complete formulation and manufacturing scale-up activities for an expected market introduction in mid-to-late 2019.
Our Strategy
Our goal is to become a leading ophthalmic biopharmaceutical company focused on developing and commercializing a strong pipeline of first-in-class microdose therapeutics and a digital health platform for interactive patient care. The key elements of our strategy to achieve this goal are:
Establish a portfolio of first-in-class piezo-print micro-therapeutic products for front-of-the-eye treatments through the 505(b)(2) pathway with the FDA.   We are initially focused on integrating our next-generation technology with therapeutic compounds already well-established in the topical treatment of ophthalmic indications. We believe that the 505(b)(2) registration pathway, which reduces development risk compared to new molecular entity programs by working with known compounds with well-established safety and efficacy profiles, will be available for our initial development pipeline. We believe our pipeline of patented micro-therapeutic product candidates will be highly differentiated by our improved tolerability and enhanced compliance profile, and our late-stage development programs could lead to NDA submissions in novel indications where the products can have unique dosing and therapeutic profiles. We believe that this could lead to favorable pricing and reimbursement, and a reduced risk of generic substitution.
Improve clinical outcomes and patient experiences while providing an improved tolerability profile with our micro-therapeutics.   We believe the Optejet will allow for high-precision targeted microdosing for front-of-the-eye treatments, while eliminating ophthalmic over-dosing and reducing ocular exposure to toxic preservatives and pharmacologic ingredients compared to conventional eyedrop delivery mechanisms. Our clinical trials have demonstrated equivalent efficacy to eyedrops, improved side effect profile and enhanced patient experience with the Optejet as compared to conventional eyedrops.
Leverage our electronic, smartphone-enabled “e-health” technology to introduce and develop patient-specific compliance monitoring program.   The mobile e-health technology within the Optejet is designed to track when a patient administers treatments, allowing physicians to track patient compliance more accurately. We believe this may enhance patient compliance and improve compliance monitoring by empowering patients and physicians with access to dynamic, real-time monitoring and compliance data for a more intelligent, informed and personalized therapeutic paradigm.
Develop microdose treatments for other ophthalmic diseases independently or in collaboration with third parties.   The Optejet is also suitable for new molecular entities. Leveraging our existing platform technology, we plan to continue developing, either independently or through strategic relationships with third parties, other product candidates for front-of-the-eye diseases that can be administered using the Optejet. We have entered into an exclusive agreement with Senju Pharmaceuticals for the Asian development and commercial rights to our therapies and technology.
Develop solutions for ophthalmic conditions with high unmet needs and no approved therapy.   We plan to target chronic ophthalmic conditions with a high unmet medical need. By leveraging our piezo-print microdosing technology, we aim to reach conditions where there are no approved drug therapies. For example, our MicroPine program involves a proprietary formulation of low-dose atropine intended to slow myopia progression in the pediatric population. There are currently no commercially-available therapies in the United States to treat this indication.
Our Team
Our management team is a critical component to the execution of our overall strategy and business model and is led by our Chief Executive Officer and Chief Medical Officer, Dr. Tsontcho Ianchulev. Dr. Ianchulev has over 15 years of experience in public health, life-science and medical technology. He is a physician-executive and public health expert who has been at the core of developing medical products and technologies that have transformed the ophthalmic field and impacted medical care for thousands of

patients each year. His intellectual property was a core asset to WaveTec’s (acquired by Alcon) technology for intraoperative aberrometry. He is currently a Professor of Ophthalmology at the New York Eye and Ear Infirmary and sits on the Boards of Kurobe Pharmaceuticals and The American Society of Cataract and Refractive Surgery Foundation. Dr. Ianchulev spent five years at Genentech, where he headed the ophthalmology research group and directed the development and FDA approval of Lucentis, a successful specialty biologic in the field of ophthalmology with more than $4 billion of annual sales in 2015. Most recently, he headed all clinical development of Transcend Medical’s (acquired by Alcon) micro-stent for glaucoma. We believe Dr. Ianchulev’s clinical experience, combined with development and commercial work in both biopharmaceuticals and medical devices make him well suited to lead Eyenovia. Dr. Ianchulev is a graduate of Harvard Medical School and has an MPH degree from the Harvard School of Public Health.
In addition to Dr. Ianchulev, the management team includes professionals with significant experience in translational science, drug evaluation, clinical development, regulatory affairs, finance, marketing and business development. Our management team is supported by our Board of Directors, which has extensive professional experience in strategic development, executive, operational and financial leadership in the pharmaceutical and healthcare industries, including several successful ophthalmology companies.

Common Stock
Our Third Amended and Restated Certificate of Incorporation, as amended, or certificate of incorporation, authorizes the issuance of 90,000,000 shares of common stock, of which 11,782,682 shares were issued and outstanding as of January 22, 2019. Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Each election of directors by our stockholders will be determined by a plurality of the votes cast by the stockholders entitled to vote on the election. Holders of common stock are entitled to receive proportionately any dividends declared by our Board of Directors, subject to any preferential dividend rights of outstanding preferred stock.
In the event of our liquidation or dissolution, the holders of our common stock are entitled to receive proportionately all assets available for distribution to stockholders after the payment of all debts and other liabilities and subject to the prior rights of any of our outstanding preferred stock. Holders of our common stock have no preemptive, subscription, redemption or conversion rights. 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 our preferred stock that we may designate and issue in the future.
Preferred Stock
Our certificate of incorporation authorizes the issuance of 6,000,000 shares of blank check preferred stock with such designation, rights and preferences as may be determined from time to time by our Board of Directors. No shares of preferred stock are currently designated and outstanding. Our Board of Directors is empowered, without stockholder approval, to issue preferred stock with dividend, liquidation, redemption, voting or other rights, which could adversely affect the voting power or other rights of the holders of common stock. We may issue some or all of the preferred stock to effect a business transaction. In addition, the preferred stock could be utilized as a method of discouraging, delaying or preventing a change in control of us.
If we sell any series of preferred stock under this prospectus and applicable prospectus supplements, we will fix the rights, preferences, privileges and restrictions of the preferred stock of such series in a certificate of amendment to our certificate of incorporation relating to that series. We will also incorporate by reference from reports that we file with the SEC, the form of any certificate of amendment that describes the terms of series of preferred stock we are offering before the issuance of the related series of preferred stock. We urge you to read the applicable prospectus supplement related to the series of preferred stock being offered, as well as the complete certificate of amendment that contains the terms of the applicable series of preferred stock.
Warrants
We may issue warrants for the purchase of common stock, preferred stock and/or debt securities (described below) in one or more series. We may issue warrants independently or together with common stock, preferred stock and/or debt securities, and the warrants may be attached to or separate from these securities. We will evidence each series of warrants by warrant certificates that we will issue under a separate agreement. We may enter into warrant agreements with a bank or trust company that we select to be our warrant agent. We will indicate the name and address of the warrant agent in the applicable prospectus supplement relating to a particular series of warrants.
In this prospectus, we have summarized certain general features of warrants. We urge you, however, to read the applicable prospectus supplement related to the particular series of warrants being offered, as well as the warrant agreements and warrant certificates that contain the terms of the warrants.

We may offer debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. The senior debt securities will rank equally with any

Any subordinated debt securities will be subordinate and junior in right of payment, to the extent and in the manner described in the instrument governing the debt, to all of our senior indebtedness. Any convertible debt securities will be convertible into or exchangeable for our common stock or our other securities. Conversion may be mandatory or at your option or both and would be at prescribed conversion rates.
With respect to any debt securities that we issue, we will issue such debt securities under an indenture, which we would enter into with the trustee named in the indenture. The form of indenture is filed as an exhibit to the registration statement of which this prospectus is a part and is incorporated herein by reference. Any indenture would be qualified under the Trust Indenture Act of 1939, as amended.
Units
We may issue units consisting of some number and/or combination of shares of our common stock; shares of our preferred stock; debt securities; warrants for such securities; or rights for the purchase of common stock, preferred stock, debt securities or units, in one or more series.

For any particular subscription rights, the applicable prospectus supplement will describe the terms of such rights, including the period during which such rights may be exercised, the manner of exercising such rights, the transferability of such rights and the number of shares of common stock, shares of preferred stock, debt securities or units that may be purchased in connection with each right and the subscription price for the purchase of such common stock, preferred stock, debt securities or units. In connection with a rights offering, we may enter into a separate agreement with one or more underwriters or purchasers to purchase any shares of our common stock, preferred stock, debt securities or units not subscribed for in the rights offering by existing stockholders, which will be described in the applicable prospectus supplement.
In this prospectus, we have summarized certain general features of rights.

RISK FACTORS
Investing in our securities involves a high degree of risk. You should consider carefully the risks and uncertainties described in “Risk Factors” in our most recently filed Annual Report on Form 10-K filed with the SEC, in each case as these risk factors are amended or supplemented by subsequent Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, or Current Reports on Form 8-K that have been or will be incorporated by reference in this prospectus. The prospectus supplement relating to a particular offering of our securities may also discuss certain risks of investing in that offering. The risks set forth in any prospectus supplement and incorporated herein by reference are those which we believe are the material risks that we face. The occurrence of any of such risks may materially and adversely affect our business, financial condition, results of operations and future prospects. In such an event, the market price of our common stock could decline, and you could lose part or all of your investment.

This prospectus contains a number of forward-looking statements. Specifically, all statements other than statements of historical facts included in this prospectus, or incorporated by reference into this prospectus, regarding our financial position, business strategy, development timelines and plans and objectives of management for future operations are forward-looking statements.

You should understand that the following important factors, in addition to those discussed in our periodic reports filed with the SEC under the Securities Exchange Act of 1934, as amended, or the Exchange Act, could affect our future results and could cause those results to differ materially from those expressed in such forward-looking statements:

Although we believe that our expectations (including those on which our forward-looking statements are based) are reasonable, we cannot assure you that those expectations will prove to be correct. Should any one or more of these risks or uncertainties materialize, or should any underlying assumptions prove incorrect, actual results may vary materially from those described in our forward-looking statements as anticipated, believed, estimated, expected or intended.

PLAN OF DISTRIBUTION
We may sell securities offered under this prospectus:

through underwriters or dealers;

through agents;

directly to one or more purchasers; or

through a combination of any of these methods for sale.
The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed from time to time, or at negotiated prices. For each type and series of securities offered, the applicable prospectus supplement will set forth the terms of the offering, including, without limitation:

the names of any underwriters, dealers or agents;

the purchase price of the securities;

the use of proceeds to us from the sale of the securities;

any underwriting discounts, agency fees or other compensation payable to underwriters or agents;

any discounts or concessions allowed or re-allowed or repaid to dealers; and

the securities exchanges on which the securities will be listed, if any.
If underwriters are used in an offering, we will execute an underwriting agreement with such underwriters and will specify the name of each underwriter and the terms of the transaction (including any underwriting discounts and other terms constituting compensation of the underwriters and any dealers) in a prospectus supplement. If we use underwriters in any sale of securities offered under this prospectus, the underwriters will buy the securities for their own account. The underwriters may then resell the securities in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale or thereafter. The underwriters may sell the securities directly or through underwriting syndicates managed by managing underwriters. The obligations of the underwriters to purchase the securities will be subject to certain conditions. The underwriters will be obligated to purchase all the securities offered if they purchase any securities. The offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time. In connection with an offering, underwriters and their affiliates may engage in transactions to stabilize, maintain, or otherwise affect the market price of the securities in accordance with applicable law.
Underwriters or agents may make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, or the Securities Act, which includes sales made directly on the Nasdaq Capital Market, the existing trading market for our common stock, or sales made to or through a market maker other than on an exchange.
If we use dealers in any sale of securities offered under this prospectus, the securities will be sold to such dealers as principals. The dealers may then resell the securities to the public at varying prices to be determined by such dealers at the time of resale. If agents are used in any sale of securities offered under this prospectus, they will generally use their reasonable best efforts to solicit purchases for the period of their appointment. If securities offered under this prospectus are sold directly, no underwriters, dealers or agents would be involved. We are not making an offer of securities in any state that does not permit such an offer.
Underwriters, dealers and agents that participate in any distribution of securities may be deemed to be underwriters as defined in the Securities Act. Any discounts, commissions or profit they receive when they resell the securities may be treated as underwriting discounts and commissions under the Securities Act. We expect that any agreements we may enter into with underwriters, dealers and agents will include provisions indemnifying them against certain civil liabilities, including certain liabilities under the Securities Act, or providing for contributions with respect to payments that they may be required to make.

TABLE OF CONTENTS
 
We may authorize underwriters, dealers or agents to solicit offers from certain institutions whereby the institution contractually agrees to purchase the securities offered under this prospectus from us on a future date at a specific price. This type of contract may be made only with institutions that we specifically approve. Such institutions could include banks, insurance companies, pension funds, investment companies, and educational and charitable institutions. The underwriters, dealers or agents will not be responsible for the validity or performance of these contracts.
Sales of securities offered under this prospectus also may be effected by us from time to time in one or more types of transactions (which may, without limitation, include block transactions, special offerings, exchange distributions, secondary distributions, purchases by a broker or dealer, or other direct sales by us to one or more purchasers) on the Nasdaq Capital Market or any other national securities exchange or automated trading and quotation system on which our common stock or other securities are listed, in the over-the-counter market, in transactions otherwise than on such exchanges and systems or the over-the-counter market, including negotiated transactions, through options transactions relating to the shares, or a combination of such methods of sale, at market prices prevailing at the time of sale, at negotiated prices, or at fixed prices. Such transactions may or may not involve brokers or dealers. Any shares of our common stock offered under this prospectus will be listed on the Nasdaq Capital Market, subject to notice of issuance.
Each issue of a new series of debt securities, preferred stock, warrants, units and rights will be a new issue of securities with no established trading market. It has not been established whether the underwriters, if any, of the securities offered under this prospectus will make a market in these securities. If a market in any series of debt securities, preferred stock, warrants, units and rights is made by any such underwriters, such market-making may be discontinued at any time without notice. We can give no assurance as to the liquidity of the trading market of these securities.
In order to facilitate the offering of any of the securities offered under this prospectus, the underwriters with respect to any such offering may, as described in the prospectus supplement, engage in transactions that stabilize, maintain, or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on these securities. Specifically, the underwriters may over-allot in connection with the offering, creating a short position in these securities for their own accounts. In addition, to cover over-allotments or to stabilize the price of these securities or of any other securities, the underwriters may bid for, and purchase, these securities or any other securities in the open market. Finally, in any offering of the securities offered under this prospectus through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing these securities in the offering, if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions, or otherwise. Any of these activities may stabilize or maintain the market price of these securities above independent market levels. The underwriters are not required to engage in these activities, and may end any of these activities at any time, all as described in the applicable prospectus supplement.
If so indicated in the applicable prospectus supplement, one or more firms, which we refer to as “remarketing firms”, acting as principals for their own accounts or as agents for us, may offer and sell the securities offered under this prospectus as part of a remarketing upon their purchase, in accordance with their terms. We will identify any remarketing firm, the terms of its agreement, if any, with us and its compensation in the applicable prospectus supplement.
Remarketing firms, agents, underwriters and dealers may be entitled under agreements with us to indemnification by or contribution from us against some civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.
Any person participating in the distribution of securities will be subject to applicable provisions of the Exchange Act, and the rules and regulations under the Exchange Act, including without limitation, Regulation M, which may limit the timing of transactions involving the securities offered under this prospectus. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of such securities to engage in market-making activities with respect to the particular securities being

distributed. All of the above may affect the marketability of the securities offered under this prospectus and the ability of any person or entity to engage in market-making activities with respect to such securities.
Under the securities laws of various states, the securities offered under this prospectus may be sold in those states only through registered or licensed brokers or dealers. In addition, in various states the securities offered under this prospectus may not be offered and sold unless such securities have been registered or qualified for sale in the state or an exemption from such registration or qualification is available and is complied with.

Common Stock
Our certificate of incorporation, authorizes the issuance of 90,000,000 shares of common stock, of which 11,782,682 shares were issued and outstanding as of January 22, 2019. Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Each election of directors by our stockholders will be determined by a plurality of the votes cast by the stockholders entitled to vote on the election. Holders of common stock are entitled to receive proportionately any dividends declared by our Board of Directors, subject to any preferential dividend rights of outstanding preferred stock.
In the event of our liquidation or dissolution, the holders of our common stock are entitled to receive proportionately all assets available for distribution to stockholders after the payment of all debts and other liabilities and subject to the prior rights of any of our outstanding preferred stock. Holders of our common stock have no preemptive, subscription, redemption or conversion rights. 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 our preferred stock that we may designate and issue in the future.
The transfer agent for our common stock is American Stock Transfer & Trust Company, LLC. The transfer agent’s address is American Stock Transfer & Trust Company, LLC 6204 15th Avenue, Brooklyn, New York 11219 and its telephone number is 800-937-5449.
Options
As of January 22, 2019, options to purchase an aggregate of 1,924,432 shares of our common stock, with a weighted average exercise price of $3.27 per share, were outstanding under our 2014 Equity Incentive Plan and 2018 Omnibus Stock Incentive Plan.
Preferred Stock
Our certificate of incorporation authorizes the issuance of 6,000,000 shares of blank check preferred stock with such designation, rights and preferences as may be determined from time to time by our Board of Directors. No shares of preferred stock are currently designated and outstanding. Our Board of Directors is empowered, without stockholder approval, to issue preferred stock with dividend, liquidation, redemption, voting or other rights, which could adversely affect the voting power or other rights of the holders of common stock. We may issue some or all of the preferred stock to effect a business transaction. In addition, the preferred stock could be utilized as a method of discouraging, delaying or preventing a change in control of us.
If we issue preferred stock, we will fix the rights, preferences, privileges, qualifications and restrictions of the preferred stock of each series that we sell under this prospectus and applicable prospectus supplements in a certificate of amendment to our certificate of incorporation relating to that series. We will also incorporate by reference into the registration statement, of which this prospectus is a part, the form of any certificate of amendment that describes the terms of series of preferred stock we are offering before the issuance of the related series of preferred stock. We urge you to read the prospectus supplement related to any series of preferred stock we may offer, as well as the complete certificate of amendment that contains the terms of the applicable series of preferred stock.
It is not possible to state the actual effect of the issuance of any shares of preferred stock upon the rights of holders of our common stock until our board of directors determines the specific rights of the holders of the preferred stock. However, these effects might include restricting dividends on the common stock, diluting the voting power of the common stock, impairing the liquidation rights of the common stock, and delaying or preventing the completion of a merger, tender offer or other takeover attempt. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our common stock.
All shares of preferred stock offered will, when issued, be fully paid and nonassessable, including shares of preferred stock issued upon the exercise or exchange of any other securities described in this prospectus.

Registration Rights
We are subject to an Investor’s Rights Agreement, as amended (the “Rights Agreement”), between us and the previous holders of our Series A preferred stock, Series A-2 preferred stock and Series B preferred stock, which shares were all converted to shares of our common stock immediately following the January 2018 initial public offering of our common stock (“IPO”). Under the Rights Agreement, beginning in July 2018, the holders of approximately 4,301,946 shares of our common stock are entitled to demand registration rights. At any time, the holders of more than specified amounts of these shares can, on not more than two occasions, request that we register all or a portion of their shares. We will not be required to effect a demand registration during the period beginning 60 days prior to our good faith estimate of the date of filing and 180 days following the effectiveness of a company-initiated registration statement relating to a public offering of our securities, such as our registration statement on Form S-1, filed with the SEC on December 12, 2018 and effective December 18, 2019.
In addition, in the event that we propose to register any of our securities under the Securities Act of 1933, as amended (“Securities Act”), either for our own account or for the account of other security holders, the holders of approximately 4,301,946 shares of our common stock are entitled to certain “piggyback” registration rights allowing such holders to include their shares in such registration, subject to certain marketing and other limitations. As a result, whenever we propose to file a registration statement under the Securities Act, other than with respect to a registration related to employee benefit plans, debt securities or corporate reorganizations, the holders of these shares are entitled to notice of the registration and have the right, subject to limitations that the underwriters may impose on the number of shares included in the registration, to include their shares in the registration. The holders of these rights have waived them with respect to this Registration Statement.
We will pay the registration expenses of the holders of the shares registered pursuant to the registrations described above.
The registration rights described above will expire upon the earlier of (i) January 2021, or (ii) with respect to any particular stockholder, the date on which such stockholder can sell all of its shares under Rule 144 of the Securities Act during any 90-day period.

DESCRIPTION OF DEBT SECURITIES
The following description, together with the additional information we include in any applicable prospectus supplement, summarizes the material terms and provisions of any debt securities that we may offer under this prospectus. While the terms we have summarized below will apply generally to any future debt securities we offer, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities we may offer under a prospectus supplement may differ from the terms described below. For any debt securities that we offer, an indenture (and any relevant supplemental indenture), if required, will contain additional important terms and provisions, the form of which we filed as an exhibit to the registration statement of which this prospectus is a part and is incorporated therein by reference. We will file any definitive indenture as an exhibit to reports that we file with the SEC and incorporate by reference in this prospectus and the applicable prospectus supplement. Any indenture would be qualified under the Trust Indenture Act of 1939, as amended.
With respect to any debt securities that we issue, we will describe in each prospectus supplement the following terms relating to a series of debt securities:

the title;

the principal amount being offered, and if a series, the total amount authorized and the total amount outstanding;

any limit on the amount that may be issued;

whether or not we will issue the series of debt securities in global form, and if so, the terms and who the depository will be;

the maturity date;

the principal amount due at maturity;

whether and under what circumstances, if any, we will pay additional amounts on any debt securities held by a person who is not a United States person for tax purposes, and whether we can redeem the debt securities if we have to pay such additional amounts;

the annual interest rate, which may be fixed or variable, or the method for determining the rate and the date interest will begin to accrue, the dates interest will be payable and the regular record dates for interest payment dates or the method for determining such dates;

whether or not the debt securities will be secured or unsecured by some or all of our assets, and the terms of any secured debt;

the terms of the subordination of any series of subordinated debt;

the place where payments will be payable;

restrictions on transfer, sale or other assignment, if any;

our right, if any, to defer payment or interest and the maximum length of any such deferral period;

We summarize below the material terms of the form of indenture, if required, or indicate which material terms will be described in the applicable prospectus supplement. The indenture:

does not limit the amount of debt securities that we may issue;

allows us to issue debt securities in one or more series;

does not require us to issue all of the debt securities of a series at the same time;

allows us to reopen a series to issue additional debt securities without the consent of the holders of the debt securities of such series; and

DESCRIPTION OF THE UNITS
We may issue units comprised of shares of common stock, shares of preferred stock, debt securities, warrants, or rights in any combination and in one or more series. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.
We may choose to evidence each series of units by unit certificates that we would issue under separate agreements. If we choose to evidence the units by unit certificate, we will enter into unit agreements with a unit agent and will indicate the name and address of the unit agent in the applicable prospectus supplement related to the particular series of units. We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of unit agreement, unit certificate, as may be applicable, and any supplemental agreements that describe the terms of the units we are offering before the issuance of the units.

DESCRIPTION OF THE RIGHTS
The following is a general description of the terms of the rights we may issue from time to time unless we provide otherwise in the applicable prospectus supplement. Particular terms of any rights we offer will be described in the prospectus supplement relating to such rights.
General
We may issue rights to purchase common stock, preferred stock, debt securities or units. Rights may be issued independently or together with other securities and may or may not be transferable by the person purchasing or receiving the rights. In connection with any rights offering to our stockholders, we may enter into a standby underwriting, backstop or other arrangements with one or more underwriters or other persons pursuant to which such underwriters or other persons would purchase any offered securities remaining unsubscribed for after such rights offering. In connection with a rights offering to our stockholders, we would distribute certificates evidencing the rights and a prospectus supplement to our stockholders on or about the record date that we set for receiving rights in such rights offering.
The applicable prospectus supplement will describe the following terms of any rights we may issue, including some or all of the following:

the title and aggregate number of the rights;

the subscription price or a formula for the determination of the subscription price for the rights and the currency or currencies in which the subscription price may be payable;

if applicable, the designation and terms of the securities with which the rights are issued and the number of rights issued with each such security or each principal amount of such security;

the number or a formula for the determination of the number of the rights issued to each stockholder;

the extent to which the rights are transferable;

in the case of rights to purchase debt securities, the principal amount of debt securities purchasable upon exercise of one right;

in the case of rights to purchase common stock or preferred stock, the type of stock and number of shares of stock purchasable upon exercise of one right;

in the case of rights to purchase units, the type and number of securities comprising the units, and the number of units purchasable upon exercise of one right;

the date on which the right to exercise the rights will commence, and the date on which the rights will expire (subject to any extension);

if applicable, the minimum or maximum amount of the rights that may be exercised at any one time;

the extent to which such rights include an over-subscription privilege with respect to unsubscribed securities;

if applicable, the procedures for adjusting the subscription price and number of shares of common stock or preferred stock purchasable upon the exercise of each right upon the occurrence of certain events, including stock splits, reverse stock splits, combinations, subdivisions or reclassifications of common stock or preferred stock;

the effect on the rights of any merger, consolidation, sale or other disposition of our business;

the terms of any rights to redeem or call the rights;

information with respect to book-entry procedures, if any;

the terms of the securities issuable upon exercise of the rights;

26

TABLE OF CONTENTS
 

any other terms of the rights, including terms, procedures and limitations relating to the exchange and exercise of the rights.
We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of rights agreement and rights certificate that describe the terms of the rights we are offering before the issuance of rights.
Exercise of Rights
Each right will entitle the holder to purchase for cash or other consideration such shares of stock or principal amount of securities at the subscription price as shall in each case be set forth in, or be determinable as set forth in, the prospectus supplement relating to the rights offered thereby. Rights may be exercised as set forth in the applicable prospectus supplement beginning on the date specified therein and continuing until the close of business on the expiration date set forth in the prospectus supplement relating to the rights offered thereby. After the close of business on the expiration date, unexercised rights will become void.
Upon receipt of payment and a rights certificate properly completed and duly executed at the corporate trust office of the subscription agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the securities purchased upon such exercise. If less than all of the rights represented by such subscription certificate are exercised, a new subscription certificate will be issued for the remaining rights. If we so indicate in the applicable prospectus supplement, holders of the rights may surrender securities as all or part of the exercise price for rights.
We may determine to offer any unsubscribed offered securities directly to stockholders, to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby underwriting, backstop or other arrangements, as described in the applicable prospectus supplement.
Prior to exercising their rights, holders of rights will not have any of the rights of holders of the securities purchasable upon subscription, including, in the case of rights to purchase common stock or preferred stock, the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise any voting rights or, in the case of rights to purchase debt securities, the right to receive principal, premium, if any, or interest payments, on the debt securities purchasable upon exercise or to enforce covenants in the applicable indenture.

CERTAIN PROVISIONS OF DELAWARE LAW, OUR
CERTIFICATE OF INCORPORATION AND BYLAWS
Provisions of our Certificate of Incorporation on Choice of Forum
Unless we consent to the selection of an alternative forum, our certificate of incorporation provides that the Court of Chancery of the State of Delaware, or the Court of Chancery, will be, to the fullest extent permitted by law, the sole and exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees or agent to the Company or our stockholders; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, or DGCL, or our certificate of incorporation or bylaws; any action to enforce or determine the validity of our certificate of incorporation or bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine. Since the choice of forum provisions are only applicable to “the fullest extent permitted by law”, as provided in our certificate of incorporation, the provisions do not designate the Court of Chancery as the exclusive forum for any derivative action or other claim for which the applicable statute creates exclusive jurisdiction in another forum. As such, the choice of forum provisions do not apply to any actions arising under the Securities Act or the Exchange Act.
We believe the choice of forum provisions in our certificate of incorporation may benefit us by providing increased consistency in the application of Delaware law, where permitted, by chancellors and judges particularly experienced in resolving corporate disputes, efficient administration of cases on a more expedited schedule relative to other forums and protection against the burdens of multi-forum litigation. However, these provisions may have the effect of discouraging lawsuits against our directors and officers in other forums. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with any applicable action brought against us, a court could find the choice of forum provisions contained in our certificate of incorporation to be inapplicable or unenforceable in such action.
Provisions of our Certificate of Incorporation and Bylaws, and Delaware Law that May Have an Anti-Takeover Effect
Certain provisions set forth in our certificate of incorporation and bylaws and Delaware law could have the effect of discouraging potential acquisition proposals or making a tender offer or delaying or preventing a change in control, including changes a stockholder might consider favorable. Such provisions may also prevent or frustrate attempts by our stockholders to replace or remove our management.
Certificate of Incorporation and Bylaws
In particular, our certificate of incorporation and bylaws, among other things:

provide that stockholders must provide advance notice to nominate persons for election to our Board of Directors or submit proposals for consideration at stockholder meetings;

specify that special meetings of our stockholders can be called only by the chairman of the Board of Directors, the President or such other persons designated by the Board of Directors; and

provide that vacancies on the Board of Directors may be filled by a majority of directors in office, although less than a quorum, or by the sole remaining director.
Delaware Law
We are subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. In general, DGCL Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years following the date on which the person became an interested stockholder unless:

prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;
 
28

TABLE OF CONTENTS
 

the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, but not the outstanding voting stock owned by the interested stockholder: (i) shares owned by persons who are directors and also officers; and (ii) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

at or subsequent to the date of the transaction, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66.67% of the outstanding voting stock that is not owned by the interested stockholder.
Generally, a business combination includes a merger, asset or stock sale, or other transaction or series of transactions together resulting in a financial benefit to the interested stockholder. 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 outstanding voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our Board of Directors does not approve in advance. We also anticipate that DGCL Section 203 may also discourage attempts that might result in a premium over the market price for the shares of common stock held by stockholders.
Certain provisions set forth in our certificate of incorporation and bylaws and Delaware law could have the effect of discouraging potential acquisition proposals or making a tender offer or delaying or preventing a change in control, including changes a stockholder might consider favorable. Such provisions may also prevent or frustrate attempts by our stockholders to replace or remove our management.
