Risks Related to COVID-19

We are relying on FDA policies and guidance provisions that have changed very recently, and may continue to change, and relate directly to the COVID-19 health crisis. If we misinterpret this guidance or the guidance changes unexpectedly and/or materially, potential sales of the COVID-19 tests would be impacted.

The U.S. Food and Drug Administration (FDA) issued non-binding guidance for manufacturers relating to the pathway to enable FDA approval for devices related to testing for COVID-19 under an Emergency Use Authorization (EUA). Following the issuance of the initial published guidance, on March 16, 2020, revised guidance specific to COVID-19 “antibody tests” was issued. Newer guidance was published on May 4, 2020 further describing the requirements for serology tests to continue to be marketed under an Emergency Use Authorization. If our interpretation of the newly revised guidance is incorrect or specifics around the guidance change, the sales of the COVID-19 test could be materially impacted.

If our recently licensed COVID-19 IgG/IgM rapid tests do not perform as expected or the reliability of the technology is questioned, we could experience delayed or reduced market acceptance of the tests, increased costs and damage to our reputation.

Our success depends on the market’s confidence that we can provide reliable, high-quality COVID-19 diagnostic tests. We believe that customers in our target markets are likely to be particularly sensitive to product defects and errors. Our reputation and the public image of our licensed COVID-19 diagnostic tests may be impaired if they fail to perform as expected or are perceived as difficult to use. Despite quality control testing, defects or errors could occur with the tests.

In the future, if our licensed COVID-19 diagnostic tests experience a material defect or error, this could result in loss or delay of revenues, delayed market acceptance, damaged reputation, diversion of development resources, legal claims, increased insurance costs or increased service and warranty costs, any of which could harm our business. Such defects or errors could also prompt us to amend certain warning labels or narrow the scope of the use of our diagnostic tests, either of which could hinder our success in the market. Even after any underlying concerns or problems are resolved, any widespread concerns regarding our technology or any manufacturing defects or performance errors in the test could result in lost revenue, delayed market acceptance, damaged reputation, increased service and warranty costs and claims against us.

If we become subject to claims relating to improper handling, storage or disposal of hazardous materials, we could incur significant cost and time to comply.

Our research and development processes involve the controlled storage, use and disposal of hazardous materials, including biological hazardous materials. We are subject to foreign, federal, state and local regulations governing the use, manufacture, storage, handling and disposal of materials and waste products. We may incur significant costs complying with both existing and future environmental laws and regulations. In particular, we are subject to regulation by the Occupational Safety and Health Administration, (OSHA), and the Environmental Protection Agency (EPA), and to regulation under the Toxic Substances Control Act and the Resource Conservation and Recovery Act in the United States. OSHA or the EPA may adopt additional regulations in the future that may affect our research and development programs. The risk of accidental contamination or injury from hazardous materials cannot be eliminated completely. In the event of an accident, we could be held liable for any damages that result, and any liability could exceed the limits or fall outside the coverage of our workers’ compensation insurance. We may not be able to maintain insurance on acceptable terms, if at all.

Our licensed COVID-19 tests have not been manufactured on a high-volume scale and could be subject to unforeseen scale-up risks.

While the manufacturers of the COVID-19 IgG/IgM rapid rests have experience manufacturing diagnostic tests, there can be no assurance that they can manufacture the COVID-19 diagnostic tests at a scale that is adequate for our current and future commercial needs. We may face significant or unforeseen difficulties in securing adequate supply of the COVID-19 diagnostic tests, relating to the manufacturing of the tests. These risks include but are not limited to:

These and other difficulties may only become apparent when scaling up to the manufacturing process of the COVID-19 diagnostic tests to a more substantive commercial scale. In the event the tests cannot be manufactured in sufficient commercial quantities or manufacturing is delayed, our future prospects could be significantly impacted and our financial prospects could be materially harmed.

Our suppliers may experience development or manufacturing problems or delays that could limit the growth of our revenue or increase our losses.

We may encounter unforeseen situations in the manufacturing of the COVID-19 diagnostic tests that could result in delays or shortfalls in our production. Suppliers may also face similar delays or shortfalls. In addition, suppliers’ production processes may have to change to accommodate any significant future expansion of manufacturing capacity, which may increase suppliers’ manufacturing costs, delay production of diagnostic tests, reduce our product gross margin and adversely impact our business. If we are unable to keep up with demand for the COVID-19 diagnostic test by successfully securing supply and shipping our diagnostic tests in a timely manner, our revenue could be impaired, market acceptance for the test could be adversely affected and our customers might instead purchase our competitors’ diagnostic tests.

We have relied and expect to continue to rely on third parties to conduct studies of the COVID-19 diagnostic tests that will be required by the FDA or other regulatory authorities and those third parties may not perform satisfactorily.

Although we intend to sell the COVID-19 IgG/IgM rapid tests by virtue of recent FDA guidance allowing for reduced product clinical and analytical studies, we have relied on third parties, such as independent testing laboratories and hospitals, to conduct such studies. Our reliance on these third parties will reduce our control over these activities. These third-party contractors may not complete activities on schedule or conduct studies in accordance with regulatory requirements or our study design. We cannot control whether they devote sufficient time, skill and resources to our studies. Our reliance on third parties that we do not control will not relieve us of any applicable requirement to prepare, and ensure compliance with, various procedures required under good clinical practices. If these third parties do not successfully carry out their contractual duties or regulatory obligations or meet expected deadlines, if the third parties need to be replaced or if the quality or accuracy of the data they obtain is compromised due to their failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our studies may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory approval for additional diagnostic tests.

If the manufacturers’ delivery of the COVID-19 tests and the required clinical data is delayed, then our ability to obtain necessary regulatory approvals and/or authorizations to distribute the COVID-19 tests will be impaired, which will adversely affect our business plans.

While the FDA has provided a path forward to begin selling the COVID-19 tests on an expedited basis, we are still required to provide the FDA with data concerning the validation of the tests and to satisfy certain labeling conditions. If the manufacturers are delayed in delivering to us the COVID-19 tests and related validation data, we will, in turn, be delayed in obtaining FDA authorization or approval required before we can begin selling the COVID-19 tests. Any such delays will adversely affect our business plans.

We rely on third parties to manufacture the COVID-19 tests for us and if such third party refuses or is unable to supply us with the COVID-19 test, our business will be materially harmed.

We rely on third parties to manufacture the COVID-19 diagnostic tests, which manufacturers licenses their rights from the owners of the intellectual property underlying the COVID-19 tests. If any issues arise with respect to the manufacturers’ ability to manufacture and deliver to us the COVID-19 tests, our business could be materially harmed.

While we have obtained an exclusive distribution agreement for the right to commercialize one of the COVID-19 test in the United States, Canada and Mexico, the manufacturer has no obligation to supply us with a minimum amount of, or any, COVID-19 tests. The manufacturer may choose not to supply us with a sufficient quantity of such tests in order to supply such tests to other distributors, or for any reason. In addition, the manufacturer may be unable to provide us with an adequate supply of COVID-19 tests for various reasons, including, among others, if it becomes insolvent, if a United States regulatory authority or other governments block the import or sale of the COVID-19 tests, if it fails to maintain its rights to manufacture the COVID-19 test, or if the owner of the underlying intellectual property fails to adequately maintain such intellectual property.

If there is little or no demand for the COVID-19 tests our business could be materially harmed.

While we have received a number of inquiries regarding the COVID-19 tests and expect to receive orders upon our receipt of a supply of COVID-19 tests, there is no guarantee that such inquiries will result in customer orders. If no orders for COVID-19 tests are made, our business will be materially harmed.

Our business may be adversely affected by the effects of the COVID-19 pandemic.

In December 2019, a novel strain of coronavirus, SARS-CoV-2, causing a disease referred to as COVID-19, was reported to have surfaced in Wuhan, China. It has since spread to multiple other countries; and, in March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. This pandemic has adversely affected or has the potential to adversely affect, among other things, the economic and financial markets and labor resources of the countries in which we operate, our manufacturing and supply chain operations, research and development efforts, commercial operations and sales force, administrative personnel, third-party service providers, business partners and customers, and the demand for some of our marketed products.

The COVID-19 pandemic has resulted in travel and other restrictions to reduce the spread of the disease, including governmental orders across the globe, which, among other things, direct individuals to shelter at their places of residence, direct businesses and governmental agencies to cease non-essential operations at physical locations, prohibit certain non-essential gatherings, maintain social distancing, and order cessation of non-essential travel. As a result of these recent developments, we have implemented work-from-home policies for a significant part of our employees. The effects of shelter-in-place and social distancing orders, government-imposed quarantines, and work-from-home policies may negatively impact productivity, disrupt our business, and delay our business timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. Such restrictions and limitations may also negatively impact our access to regulatory authorities (which may be affected, among other things, by travel restrictions and may be delayed in responding to inquiries, reviewing filings, and conducting inspections). The COVID-19 pandemic may also result in the loss of some of our key personnel, either temporarily or permanently. In addition, our sales and marketing efforts may be impacted by postponement of face-to-face meetings and restrictions on access by non-essential personnel to hospitals or clinics, all of which could slow adoption and implementation of our marketed products, resulting in lower net product sales. For example, while the impact of shelter-in-place and social distancing orders, physicians’ office closures, and delays in the treatment of patients following the COVID-19 pandemic on our net product sales of our products for the three months ended March 31, 2020 was limited, overall demand was lower in April 2020 compared to the same period of 2019. In addition to other potential impacts of the COVID-19 pandemic on net product sales, we expect to see continued adverse impact on new patient starts for all products while these measures remain in place. See Part I, Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations” for a discussion of our net product sales. Demand for some or all of our marketed products may continue to be reduced while the shelter-in-place or social distancing orders are in effect and, as a result, some of our inventory may become obsolete and may need to be written off, impacting our operating results. These and similar, and perhaps more severe, disruptions in our operations may materially adversely impact our business, operating results, and financial condition.

Quarantines, shelter-in-place, social distancing, and similar government orders (or the perception that such orders, shutdowns, or other restrictions on the conduct of business operations could occur) related to COVID-19 or other infectious diseases are impacting personnel at our research and manufacturing facilities, our suppliers, and other third parties on which we rely, and may impact the availability or cost of materials produced by or purchased from such parties, which could result in a disruption in our supply chain.

In addition, infections and deaths related to COVID-19 may disrupt the United States’ healthcare and healthcare regulatory systems. Such disruptions could divert healthcare resources away from, or materially delay, FDA review and potential approval of our marketed products. It is unknown how long these disruptions could continue. Further, while we are focused on therapies to address the COVID-19 pandemic, our other product candidates may need to be de-prioritized. Any elongation or de-prioritization of our other products could materially affect our business.

While the potential economic impact brought by, and the duration of, the COVID-19 pandemic may be difficult to assess or predict, it is currently resulting in significant disruption of global financial markets. This disruption, if sustained or recurrent, could make it more difficult for us to access capital if needed. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our business and the value of our common stock. The global COVID-19 pandemic continues to rapidly evolve. The ultimate impact of this pandemic is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, healthcare systems, or the global economy as a whole. These effects could have a material impact on our operations. To the extent the COVID-19 pandemic adversely affects our business, prospects, operating results, or financial condition, it may also materially affect our business.

Risks Related to the Healight Technology

We must rely on a third party to develop and commercialize the Healight Technology.

We must rely on Cedars-Sinai Medical Center to conduct testing and clinical trials of the Healight Technology (“Healight”). As a result, we are expected to remain dependent on a third party to conduct ongoing trials and the timing and completion of these trials will be partially controlled by such third party and may result in delays to the Healight development program. Nevertheless, we are responsible for ensuring that each of the trials is conducted in accordance with the applicable protocol and legal, regulatory, and scientific standards and our reliance on a third party does not relieve us of our regulatory responsibilities. If we or Cedars-Sinai Medical Center fail to comply with applicable requirements, the FDA may require to perform additional clinical tests.

There is no guarantee that Cedars-Sinai Medical Center will devote adequate time and resources to the Healight development activities or perform as contractually required. Furthermore, Cedars-Sinai Medical Center may also have relationships with other entities, some of which may be our competitors. If Cedars-Sinai Medical Center fails to meet expected deadlines, adhere to our clinical protocols, meet regulatory requirements, or otherwise performs in a substandard manner, or terminates its engagement with us, the timelines for the Healight technology development may be extend, delayed, suspended, or terminated.

The development of Healight faces uncertainties related to testing.

The development of Healight is based on scientific hypotheses and experimental approaches that may not lead to desired results. It is possible that the timeframe for obtaining proof of principle and other results may be considerably longer than originally anticipated, or may not be possible given time, resource, financial, strategic, and collaborator constraints. Success in one stage of testing is not necessarily an indication that the Healight program will succeed in later stages of testing and development. The discovery of unexpected side effects, inability to increase scale of manufacture, market attractiveness, regulatory hurdles, competition, as well as other factors may make the Healight technology unattractive of unsuitable for human use.

Risks Related to our Bylaws

Our Amended and Restated Bylaws provides that the Court of Chancery of the State of Delaware is the exclusive forum for certain litigation that may be initiated by our stockholders, including claims under the Securities Act, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our Amended and Restated Bylaws provides that the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim for breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws or (iv) any action asserting a claim governed by the internal affairs doctrine. The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and our directors, officers, employees and agents. Stockholders who do bring a claim in the Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near the State of Delaware. The Court of Chancery may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. Alternatively, if a court were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition. Notwithstanding the foregoing, the exclusive provision shall not preclude or contract the scope of exclusive federal or concurrent jurisdiction for actions brought under the Exchange Act, or the Securities Act of 1933, as amended, or the Securities Act, or the respective rules and regulations promulgated thereunder.

USE OF PROCEEDS

We intend to use the net proceeds from the sales of the securities described in this prospectus as set forth in the applicable prospectus supplement.

DESCRIPTION OF DEBT SECURITIES

This section describes the general terms and provisions of the debt securities that we may offer using this prospectus and the related indenture. This section is only a summary and does not purport to be complete. You must look to the relevant form of debt security and the related indenture for a full understanding of all terms of any series of debt securities. The form of debt security and the related indenture have been or will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information” for information on how to obtain copies.

We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, 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 offered under a prospectus supplement may differ from the terms described below. Unless otherwise mentioned or unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue the debt securities under the indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. We have filed the form of indenture as an exhibit to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The following summary of material provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indenture that contains the terms of the debt securities.

General

The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit that we may designate. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us.

We may issue the debt securities issued under the indenture as “discount securities,” which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with “original issue discount,” or OID, for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be described in more detail in the applicable prospectus supplement.

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

Conversion or Exchange Rights

We will set forth in the applicable prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for our common stock or our other securities. We will include provisions as to settlement upon conversion or exchange and whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our common stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger or Sale

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indenture will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of our assets as an entirety or substantially as an entirety. However, any successor to or acquirer of such assets (other than a subsidiary of ours) must assume all of our obligations under the indenture or the debt securities, as appropriate.

Events of Default under the Indenture

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the following are events of default under the indenture with respect to any series of debt securities that we may issue:

If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the trustee if notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, of such series of debt securities due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the principal amount of and accrued interest, if any, of each issue of debt securities then outstanding shall be due and payable without any notice or other action on the part of the trustee or any holder.

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

Subject to the terms of the indenture, if an event of default under an indenture shall occur and be continuing, the trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series, provided that:

A holder of the debt securities of any series will have the right to institute a proceeding under the indenture or to appoint a receiver or trustee, or to seek other remedies only if:

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

We will periodically file statements with the trustee regarding our compliance with specified covenants in the indenture.

Modification of Indenture; Waiver

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the trustee may change an indenture without the consent of any holders with respect to specific matters:

In addition, under the indenture, the rights of holders of a series of debt securities may be changed by us and the trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the trustee may make the following changes only with the consent of each holder of any outstanding debt securities affected:

Discharge

The indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

In order to exercise our rights to be discharged, we must deposit with the trustee money or government obligations sufficient to pay all the principal of, any premium, if any, and interest on, the debt securities of the series on the dates payments are due.

We will issue the debt securities of each series only in fully registered form without coupons and, unless we provide otherwise in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indenture provides that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company, or DTC, or another depositary named by us and identified in the applicable prospectus supplement with respect to that series. To the extent the debt securities of a series are issued in global form and as book-entry, a description of terms relating to any book-entry securities will be set forth in the applicable prospectus supplement.

At the option of the holder, subject to the terms of the indenture and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the indenture and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will impose no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If we elect to redeem the debt securities of any series, we will not be required to:

Information Concerning the Trustee

The trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the trustee is under no obligation to exercise any of the powers given it by the indenture at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement, we will designate the corporate trust office of the trustee as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the trustee for the payment of the principal of or any premium or interest on any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

Governing Law

The indenture and the debt securities, and any claim, controversy or dispute arising under or related to the indenture or the debt securities, will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

DESCRIPTION OF CAPITAL STOCK

General

This prospectus describes the general terms of our capital stock. For a more detailed description of our capital stock, you should read the applicable provisions of the Delaware General Corporation Law, or DGCL, and our charter and bylaws.

Our certificate of incorporation provides that we may issue up to 200,000,000 shares of common stock, par value $0.0001 per share, and up to 50,000,000 shares of preferred stock, par value $0.0001 per share, and permits our board of directors, without stockholder approval, to amend the charter to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that we have authority to issue. As of June 1, 2020, there were 120,614,876 shares of our common stock outstanding and no shares of our preferred stock outstanding. Under Delaware law, stockholders generally are not personally liable for our debts or obligations solely as a result of their status as stockholders.

Common Stock

Holders of our common stock generally have no preference, conversion, exchange, sinking fund, redemption or appraisal rights and have no preemptive rights to subscribe for any of our securities. Holders of our common stock are entitled to receive dividends when authorized by our board of directors out of assets legally available for the payment of dividends. They are also entitled to share ratably in our assets legally available for distribution to our stockholders in the event of our liquidation, dissolution or winding up, after payment of or adequate provision for all of our known debts and liabilities. These rights are subject to the preferential rights of any other class or series of our stock. The outstanding shares of common stock are, and any shares offered by this prospectus will be when issued and paid for, fully paid and nonassessable.

Each outstanding share of common stock entitles the holder to one vote on all matters submitted to a vote of stockholders, including the election of directors. Except as provided with respect to any other class or series of stock, the holders of our common stock will possess the exclusive voting power. In uncontested elections, directors are elected by a majority of all of the votes cast in the election of directors, and in contested elections, directors are elected by a plurality of all of the votes cast in the election of directors.

Preferred Stock

Our board of directors has the authority, without stockholder approval, to issue, at any time and from time to time, up to 50,000,000 shares of our preferred stock in one or more classes or series. Each such class or series shall have such preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption as shall be determined by our board of directors and set forth in articles supplementary relating to such class or series. The rights of the holders of our common stock will be subject to, and may be adversely affected by, the rights of holders of any preferred stock that may be issued in the future. Such rights may include voting and conversion rights which could adversely affect the holders of the common stock. Satisfaction of any dividend or liquidation preferences of outstanding preferred stock would reduce the amount of funds available, if any, for the payment of dividends or liquidation amounts on common stock.

A prospectus supplement, relating to any offered class or series of preferred stock, will specify the following terms of such class or series, as applicable:

Transfer Agent and Registrar

The transfer agent of our common stock is Issuer Direct Corporation. Their address is 500 Perimeter Park Drive, Suite D, Morrisville, NC 27560.

DESCRIPTION OF OTHER SECURITIES

Warrants

We may issue warrants to purchase the securities described in this prospectus. Unless otherwise provided in the applicable prospectus supplement, each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. Additional information regarding any warrants we may offer and the related warrant agreement will be set forth in the applicable prospectus supplement. As of June 1, 2020, the following warrants were outstanding:

Each of these warrants entitles the holder to purchase one share of common stock at prices ranging between $1.25 and $3,120, as converted, per share, with a weighted average exercise price of $3.78 per share. Certain of these warrants has a net exercise provision under which its holder may, in lieu of payment of the exercise price in cash, surrender the warrant and receive a net amount of shares based on the fair market value of our common stock at the time of exercise of the warrant after deduction of the aggregate exercise price. Each of these warrants also contains provisions for the adjustment of the exercise price and the aggregate number of shares issuable upon the exercise of the warrant in the event of dividends, share splits, reorganizations and reclassifications and consolidations. Certain of these warrants contain a provision requiring a reduction to the exercise price in the event we issue common stock, or securities convertible into or exercisable for common stock, at a price per share lower than the warrant exercise price.

Rights

We may issue rights to purchase our common stock, preferred stock, or warrants in one or more series. Rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the subscription rights. In connection with any rights offering to our stockholders, we may enter into a standby underwriting arrangement with one or more underwriters pursuant to which the underwriters will purchase any of the offered securities remaining unsubscribed after the expiration of the rights offering. In connection with a rights offering to our shareholders, we will distribute certificates evidencing the rights and an applicable prospectus supplement to our shareholders on the record date that we set for receiving rights in the rights offering.

The particular terms and provisions of the rights offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply thereto, will be described in the prospectus supplement filed in respect of such units. This description will include, where applicable:

Units

We may issue units comprised of one or more of the securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement, if any, under which a unit is issued may provide that the securities comprising the unit may not be held or transferred separately, at any time or at any time before a specified date.

The particular terms and provisions of units offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply thereto, will be described in the prospectus supplement filed in respect of such units. This description will include, where applicable:

We reserve the right to set forth in a prospectus supplement specific terms of the units that are not within the options and parameters set forth in this prospectus. In addition, to the extent that any particular terms of the units described in a prospectus supplement differ from any of the terms described in this prospectus, the description of such terms set forth in this prospectus shall be deemed to have been superseded by the description of the differing terms set forth in such prospectus supplement with respect to such units.

PLAN OF DISTRIBUTION

We may sell the securities from time to time pursuant to underwritten public offerings, direct sales to the public, negotiated transactions, block trades or a combination of these methods. We may sell the securities to or through underwriters or dealers, through agents, directly to one or more purchasers, or through any combination of these methods. 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, at market prices prevailing at the time of sale, at prices related to the prevailing market prices or at negotiated prices.

We may issue securities to other companies or their security holders to acquire those companies or equity interests in those companies, or to acquire assets of those companies, through mergers or consolidations with us or any of our subsidiaries, or through the exchange of our securities for securities of the other companies, or through the exchange of assets of other companies for our securities, or through similar transactions. We may also issue securities to third parties to acquire patents or other intellectual property or licenses or similar rights to use patents or other intellectual property.

A prospectus supplement or supplements (and any related free writing prospectus that we may authorize to be provided to you) will describe the terms of the offering of the securities, including, to the extent applicable:

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.

By Underwriters

If underwriters are used in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities offered by the prospectus supplement. Any public offering price and any discounts or concessions allowed or reallowed may change from time to time. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

By Dealers

If a dealer is utilized in the sale of any securities offered by this prospectus, we will sell those securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. We will set forth the names of the dealers and the terms of the transaction in the applicable prospectus supplement.

By Agents

We may sell securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best-efforts basis for the period of its appointment.

By Direct Sales

We may also directly sell securities offered by this prospectus. In this case, no underwriters or agents would be involved. We will describe the terms of those sales in the applicable prospectus supplement.

Electronic Auctions

We also may make sales through the Internet or through other electronic means. Since we may from time to time elect to offer securities directly to the public, with or without the involvement of agents, underwriters or dealers, utilizing the Internet or other forms of electronic bidding or ordering systems for the pricing and allocation of the securities, you will want to pay particular attention to the description of that system we will provide in an applicable prospectus supplement.

The electronic system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and which may directly affect the price or other terms and conditions at which the securities are sold. These bidding or ordering systems may present to each bidder, on a so-called “real-time” basis, relevant information to assist in making a bid, such as the clearing spread at which the offering would be sold, based on the bids submitted, and whether a bidder’s individual bids would be accepted, prorated or rejected. Of course, many pricing methods can and may also be used.

Upon completion of the electronic auction process, securities will be allocated based on prices bid, terms of bid or other factors. The final offering price at which securities would be sold and the allocation of securities among bidders would be based in whole or in part on the results of the Internet or other electronic bidding process or auction.

General Information

Underwriters, dealers and agents that participate in the distribution of the securities offered by this prospectus may be deemed underwriters under the Securities Act, and any discounts or commissions they receive from us and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the Securities Act.

We may authorize agents, dealers or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

We may provide agents and underwriters with indemnification against civil liabilities related to this offering, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.

Some or all of the securities we offer, other than shares of common stock, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

We may engage in at-the-market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of shares, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of shares. The third parties in such sale transactions will be identified in the applicable prospectus supplement.

One or more firms, referred to as “remarketing firms,” may also offer or sell the securities, if the prospectus supplement so indicates, in connection with a remarketing arrangement upon their purchase. Remarketing firms will act as principals for their own accounts or as agents for us. These remarketing firms will offer or sell the securities in accordance with the terms of the securities. The prospectus supplement will identify any remarketing firm and the terms of its agreement, if any, with us and will describe the remarketing firm’s compensation. Remarketing firms may be deemed to be underwriters in connection with the securities they remarket.

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position. This short sales position may involve either “covered” short sales or “naked” short sales. Covered short sales are short sales made in an amount not greater than the underwriters’ over-allotment option to purchase additional securities in this offering described above. The underwriters may close out any covered short position either by exercising their over-allotment option or by purchasing securities in the open market. To determine how they will close the covered short position, the underwriters will consider, among other things, the price of securities available for purchase in the open market, as compared to the price at which they may purchase securities through the over-allotment option. Naked short sales are short sales in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing securities in the open market. A naked short position is more likely to be created if the underwriters are concerned that, in the open market after pricing, there may be downward pressure on the price of the securities that could adversely affect investors who purchase securities in this offering. Stabilizing transactions permit bids to purchase the underlying security for the purpose of fixing the price of the security so long as the stabilizing bids do not exceed a specified maximum. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions.

Any underwriters who are qualified market makers on The Nasdaq Capital Market may engage in passive market making transactions in our common stock, preferred stock, warrants, units and debt securities, as applicable, on The Nasdaq Capital Market in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the securities. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.

Similar to other purchase transactions, an underwriter’s purchase to cover the syndicate short sales or to stabilize the market price of our securities may have the effect of raising or maintaining the market price of our securities or preventing or mitigating a decline in the market price of our securities. As a result, the price of our securities may be higher than the price that might otherwise exist in the open market. The imposition of a penalty bid might also have an effect on the price of the securities if it discourages resales of the securities.

Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of the securities. If such transactions are commenced, they may be discontinued without notice at any time.

The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business for which they receive compensation.

LEGAL MATTERS

Certain legal matters in connection with the offered securities will be passed upon for us by Dorsey & Whitney LLP, Salt Lake City, Utah. Any underwriters or agents will be represented by their own legal counsel, who will be identified in the applicable prospectus supplement.

FORWARD-LOOKING STATEMENTS

This prospectus, and the documents incorporated by reference herein, contain certain “forward-looking statements” within the meaning of Section 27A of the Securities Act, Section 21E of the Exchange Act and the Private Securities Litigation Reform Act of 1995, and are based on management’s current expectations.

Various factors could adversely affect our operations, business or financial results in the future and cause our actual results to differ materially from those contained in the forward-looking statements, including those factors discussed under “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” or otherwise discussed in our Annual Report on Form 10-K for the fiscal year ended June 30, 2019, our Quarterly Reports on Form 10-Q for the quarterly periods ended December 31, 2019 and March 31, 2020, and in our other filings made from time to time with the SEC after the date of this prospectus.

For additional information about factors that could cause actual results to differ materially from those described in the forward-looking statements, please see the documents that we have filed with the SEC, including our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other documents and reports filed from time to time with the SEC.

RISK FACTORS

Investing in our common stock is speculative and involves a high degree of risk. Before making an investment decision, you should carefully consider the risks described in this prospectus supplement and the documents incorporated by reference into this prospectus supplement, including the “Risk Factors” section of our Annual Report on Form 10-K for the year ended June 31, 2019, which is incorporated by reference into this prospectus supplement, as updated by annual, quarterly and other reports and documents we file with the SEC after the date of this prospectus supplement and that are incorporated by reference into this prospectus supplement. If any of these risks actually occurs, our business, financial condition or results of operations could be materially adversely affected. These risks and uncertainties are not the only ones faced by us. Additional risks and uncertainties, including those of which we are currently unaware or that are currently deemed immaterial, may also materially and adversely affect our business, financial condition, cash flows, prospects and the price of our common stock.

Risks Related to COVID-19

We are relying on FDA policies and guidance provisions that have changed very recently, and may continue to change, and relate directly to the COVID-19 health crisis. If we misinterpret this guidance or the guidance changes unexpectedly and/or materially, potential sales of the COVID-19 tests would be impacted.

The U.S. Food and Drug Administration (FDA) issued non-binding guidance for manufacturers relating to the pathway to enable FDA approval for devices related to testing for COVID-19 under an Emergency Use Authorization (EUA). Following the issuance of the initial published guidance, on March 16, 2020, revised guidance specific to COVID-19 “antibody tests” was issued. Newer guidance was published on May 4, 2020 further describing the requirements for serology tests to continue to be marketed under an Emergency Use Authorization. If our interpretation of the newly revised guidance is incorrect or specifics around the guidance change, the sales of the COVID-19 test could be materially impacted.

If our recently licensed COVID-19 IgG/IgM rapid tests do not perform as expected or the reliability of the technology is questioned, we could experience delayed or reduced market acceptance of the tests, increased costs and damage to our reputation.

Our success depends on the market’s confidence that we can provide reliable, high-quality COVID-19 diagnostic tests. We believe that customers in our target markets are likely to be particularly sensitive to product defects and errors. Our reputation and the public image of our licensed COVID-19 diagnostic tests may be impaired if they fail to perform as expected or are perceived as difficult to use. Despite quality control testing, defects or errors could occur with the tests.

In the future, if our licensed COVID-19 diagnostic tests experience a material defect or error, this could result in loss or delay of revenues, delayed market acceptance, damaged reputation, diversion of development resources, legal claims, increased insurance costs or increased service and warranty costs, any of which could harm our business. Such defects or errors could also prompt us to amend certain warning labels or narrow the scope of the use of our diagnostic tests, either of which could hinder our success in the market. Even after any underlying concerns or problems are resolved, any widespread concerns regarding our technology or any manufacturing defects or performance errors in the test could result in lost revenue, delayed market acceptance, damaged reputation, increased service and warranty costs and claims against us.

If we become subject to claims relating to improper handling, storage or disposal of hazardous materials, we could incur significant cost and time to comply.

Our research and development processes involve the controlled storage, use and disposal of hazardous materials, including biological hazardous materials. We are subject to foreign, federal, state and local regulations governing the use, manufacture, storage, handling and disposal of materials and waste products. We may incur significant costs complying with both existing and future environmental laws and regulations. In particular, we are subject to regulation by the Occupational Safety and Health Administration, (OSHA), and the Environmental Protection Agency (EPA), and to regulation under the Toxic Substances Control Act and the Resource Conservation and Recovery Act in the United States. OSHA or the EPA may adopt additional regulations in the future that may affect our research and development programs. The risk of accidental contamination or injury from hazardous materials cannot be eliminated completely. In the event of an accident, we could be held liable for any damages that result, and any liability could exceed the limits or fall outside the coverage of our workers’ compensation insurance. We may not be able to maintain insurance on acceptable terms, if at all.

Our licensed COVID-19 tests have not been manufactured on a high-volume scale and could be subject to unforeseen scale-up risks.

While the manufacturers of the COVID-19 IgG/IgM rapid rests have experience manufacturing diagnostic tests, there can be no assurance that they can manufacture the COVID-19 diagnostic tests at a scale that is adequate for our current and future commercial needs. We may face significant or unforeseen difficulties in securing adequate supply of the COVID-19 diagnostic tests, relating to the manufacturing of the tests. These risks include but are not limited to:

These and other difficulties may only become apparent when scaling up to the manufacturing process of the COVID-19 diagnostic tests to a more substantive commercial scale. In the event the tests cannot be manufactured in sufficient commercial quantities or manufacturing is delayed, our future prospects could be significantly impacted and our financial prospects could be materially harmed.

Our suppliers may experience development or manufacturing problems or delays that could limit the growth of our revenue or increase our losses.

We may encounter unforeseen situations in the manufacturing of the COVID-19 diagnostic tests that could result in delays or shortfalls in our production. Suppliers may also face similar delays or shortfalls. In addition, suppliers’ production processes may have to change to accommodate any significant future expansion of manufacturing capacity, which may increase suppliers’ manufacturing costs, delay production of diagnostic tests, reduce our product gross margin and adversely impact our business. If we are unable to keep up with demand for the COVID-19 diagnostic test by successfully securing supply and shipping our diagnostic tests in a timely manner, our revenue could be impaired, market acceptance for the test could be adversely affected and our customers might instead purchase our competitors’ diagnostic tests.

We have relied and expect to continue to rely on third parties to conduct studies of the COVID-19 diagnostic tests that will be required by the FDA or other regulatory authorities and those third parties may not perform satisfactorily.

Although we intend to sell the COVID-19 IgG/IgM rapid tests by virtue of recent FDA guidance allowing for reduced product clinical and analytical studies, we have relied on third parties, such as independent testing laboratories and hospitals, to conduct such studies. Our reliance on these third parties will reduce our control over these activities. These third-party contractors may not complete activities on schedule or conduct studies in accordance with regulatory requirements or our study design. We cannot control whether they devote sufficient time, skill and resources to our studies. Our reliance on third parties that we do not control will not relieve us of any applicable requirement to prepare, and ensure compliance with, various procedures required under good clinical practices. If these third parties do not successfully carry out their contractual duties or regulatory obligations or meet expected deadlines, if the third parties need to be replaced or if the quality or accuracy of the data they obtain is compromised due to their failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our studies may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory approval for additional diagnostic tests.

If the manufacturers’ delivery of the COVID-19 tests and the required clinical data is delayed, then our ability to obtain necessary regulatory approvals and/or authorizations to distribute the COVID-19 tests will be impaired, which will adversely affect our business plans.

While the FDA has provided a path forward to begin selling the COVID-19 tests on an expedited basis, we are still required to provide the FDA with data concerning the validation of the tests and to satisfy certain labeling conditions. If the manufacturers are delayed in delivering to us the COVID-19 tests and related validation data, we will, in turn, be delayed in obtaining FDA authorization or approval required before we can begin selling the COVID-19 tests. Any such delays will adversely affect our business plans.

We rely on third parties to manufacture the COVID-19 tests for us and if such third party refuses or is unable to supply us with the COVID-19 test, our business will be materially harmed.

We rely on third parties to manufacture the COVID-19 diagnostic tests, which manufacturers licenses their rights from the owners of the intellectual property underlying the COVID-19 tests. If any issues arise with respect to the manufacturers’ ability to manufacture and deliver to us the COVID-19 tests, our business could be materially harmed.

While we have obtained an exclusive distribution agreement for the right to commercialize one of the COVID-19 test in the United States, Canada and Mexico, the manufacturer has no obligation to supply us with a minimum amount of, or any, COVID-19 tests. The manufacturer may choose not to supply us with a sufficient quantity of such tests in order to supply such tests to other distributors, or for any reason. In addition, the manufacturer may be unable to provide us with an adequate supply of COVID-19 tests for various reasons, including, among others, if it becomes insolvent, if a United States regulatory authority or other governments block the import or sale of the COVID-19 tests, if it fails to maintain its rights to manufacture the COVID-19 test, or if the owner of the underlying intellectual property fails to adequately maintain such intellectual property.

If there is little or no demand for the COVID-19 tests our business could be materially harmed.

While we have received a number of inquiries regarding the COVID-19 tests and expect to receive orders upon our receipt of a supply of COVID-19 tests, there is no guarantee that such inquiries will result in customer orders. If no orders for COVID-19 tests are made, our business will be materially harmed.

Our business may be adversely affected by the effects of the COVID-19 pandemic.

In December 2019, a novel strain of coronavirus, SARS-CoV-2, causing a disease referred to as COVID-19, was reported to have surfaced in Wuhan, China. It has since spread to multiple other countries; and, in March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. This pandemic has adversely affected or has the potential to adversely affect, among other things, the economic and financial markets and labor resources of the countries in which we operate, our manufacturing and supply chain operations, research and development efforts, commercial operations and sales force, administrative personnel, third-party service providers, business partners and customers, and the demand for some of our marketed products.

The COVID-19 pandemic has resulted in travel and other restrictions to reduce the spread of the disease, including governmental orders across the globe, which, among other things, direct individuals to shelter at their places of residence, direct businesses and governmental agencies to cease non-essential operations at physical locations, prohibit certain non-essential gatherings, maintain social distancing, and order cessation of non-essential travel. As a result of these recent developments, we have implemented work-from-home policies for a significant part of our employees. The effects of shelter-in-place and social distancing orders, government-imposed quarantines, and work-from-home policies may negatively impact productivity, disrupt our business, and delay our business timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. Such restrictions and limitations may also negatively impact our access to regulatory authorities (which may be affected, among other things, by travel restrictions and may be delayed in responding to inquiries, reviewing filings, and conducting inspections). The COVID-19 pandemic may also result in the loss of some of our key personnel, either temporarily or permanently. In addition, our sales and marketing efforts may be impacted by postponement of face-to-face meetings and restrictions on access by non-essential personnel to hospitals or clinics, all of which could slow adoption and implementation of our marketed products, resulting in lower net product sales. For example, while the impact of shelter-in-place and social distancing orders, physicians’ office closures, and delays in the treatment of patients following the COVID-19 pandemic on our net product sales of our products for the three months ended March 31, 2020 was limited, overall demand was lower in April 2020 compared to the same period of 2019. In addition to other potential impacts of the COVID-19 pandemic on net product sales, we expect to see continued adverse impact on new patient starts for all products while these measures remain in place. See Part I, Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations” for a discussion of our net product sales. Demand for some or all of our marketed products may continue to be reduced while the shelter-in-place or social distancing orders are in effect and, as a result, some of our inventory may become obsolete and may need to be written off, impacting our operating results. These and similar, and perhaps more severe, disruptions in our operations may materially adversely impact our business, operating results, and financial condition.

Quarantines, shelter-in-place, social distancing, and similar government orders (or the perception that such orders, shutdowns, or other restrictions on the conduct of business operations could occur) related to COVID-19 or other infectious diseases are impacting personnel at our research and manufacturing facilities, our suppliers, and other third parties on which we rely, and may impact the availability or cost of materials produced by or purchased from such parties, which could result in a disruption in our supply chain.

In addition, infections and deaths related to COVID-19 may disrupt the United States’ healthcare and healthcare regulatory systems. Such disruptions could divert healthcare resources away from, or materially delay, FDA review and potential approval of our marketed products. It is unknown how long these disruptions could continue. Further, while we are focused on therapies to address the COVID-19 pandemic, our other product candidates may need to be de-prioritized. Any elongation or de-prioritization of our other products could materially affect our business.

While the potential economic impact brought by, and the duration of, the COVID-19 pandemic may be difficult to assess or predict, it is currently resulting in significant disruption of global financial markets. This disruption, if sustained or recurrent, could make it more difficult for us to access capital if needed. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our business and the value of our common stock. The global COVID-19 pandemic continues to rapidly evolve. The ultimate impact of this pandemic is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, healthcare systems, or the global economy as a whole. These effects could have a material impact on our operations. To the extent the COVID-19 pandemic adversely affects our business, prospects, operating results, or financial condition, it may also materially affect our business

Risks Related to This Offering

A substantial number of common stock may be sold in the market following this offering, which may depress the market price for our common stock.

Sales of a substantial number of our common stock in the public market following this offering could cause the market price of our common stock to decline. Although there can be no assurance that any of the $40.0 million worth of common stock being offered under this prospectus supplement will be sold or the price at which any such shares might be sold, assuming that an aggregate of 25,316,455 of our common stock are sold during the term of the sales agreement with Jefferies, in each case, for example, at a price of $1.58 per share, the last reported sale price of our common stock on the Nasdaq Capital Market on June 1, 2020, upon completion of this offering, based on 120,614,876 shares of our common stock outstanding as of June 1, 2020, we will have outstanding an aggregate of 145,931,331 common stock, assuming no exercise of outstanding options.

Additional dilution may result from the issuance of our common stock in connection with collaborations or other financing efforts.

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

In order to raise additional capital, we may in the future offer additional common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the price per share in this offering. We may sell common stock or other securities convertible into or exchangeable for our common stock in any other offering at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing common stock or other securities convertible into or exchangeable for our common stock in the future could have rights superior to existing shareholders. The price per share at which we sell additional common stock or other securities convertible or exchangeable into our common stock, in future transactions may be higher or lower than the price per share paid by investors in this offering.

We have broad discretion in how we use the net proceeds of this offering, and we may not use these proceeds effectively or in ways with which you agree.

We have not designated any portion of the net proceeds from this offering to be used for any particular purpose. Our management will have broad discretion as to the application of the net proceeds of this offering and could use them for purposes other than those contemplated at the time of this offering. Our shareholders may not agree with the manner in which our management chooses to allocate and spend the net proceeds. Moreover, our management may use the net proceeds for corporate purposes that may not increase the market price of our common stock.

Investors in this offering will experience immediate dilution in the book value per share of the common stock purchased in the offering.

The common stock sold in this offering, if any, will be sold from time to time at various prices. However, the expected offering price of our common stock will be substantially higher than the net tangible book value per share of our outstanding common stock. After giving effect to the sale of our common stock in the aggregate amount of $40.0 million at an assumed offering price of $1.58 per share, the last reported sale price of our common stock on June 1, 2020 on the Nasdaq Capital Market, and after deducting estimated commissions and estimated offering expenses, our as-adjusted net tangible book value as of March 31, 2020 would have been approximately $49.8 million, or approximately $0.40 per share of common stock. This represents an immediate increase in net tangible book value of approximately $0.29 per share of common stock to our existing shareholders and an immediate dilution in as-adjusted net tangible book value of approximately $1.18 per share to new investors of our common stock in this offering. See “Dilution” on page S-13 of this prospectus supplement.

The actual number of shares we will issue under the sales agreement with Jefferies, at any one time or in total, is uncertain.

Subject to certain limitations in the sales agreement with Jefferies and compliance with applicable law, we have the discretion to deliver placement notices to Jefferies at any time throughout the term of the sales agreement. The number of shares that are sold by Jefferies after delivering a placement notice will fluctuate based on the market price of the common stock during the sales period and limits we set with Jefferies.

We do not expect to pay dividends in the foreseeable future. As a result, you must rely on stock appreciation for any return on your investment.

We do not anticipate paying cash dividends on our common stock in the foreseeable future. Any payment of cash dividends will also depend on our financial condition, results of operations, capital requirements and other factors and will be at the discretion of our board of directors. Accordingly, you will have to rely on capital appreciation, if any, to earn a return on your investment in our common stock. Furthermore, we may in the future become subject to additional contractual restrictions on, or prohibitions against, the payment of dividends.

USE OF PROCEEDS

We may issue and sell our common stock having aggregate sales proceeds of up to $40.0 million 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, in the future, we will sell any shares under or fully utilize the sales agreement with Jefferies as a source of financing.

We currently intend to use the net proceeds from this offering for working capital and general corporate purposes, which may include capital expenditures, research and development expenditures, preclinical study and clinical trial expenditures, acquisitions of new technologies and investments and business combinations.

The precise amount and timing of the application of these net proceeds will depend upon a number of factors, such as the timing and progress of our research and development efforts and the timing and progress of any partnering efforts. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds from this offering. Depending on the outcome of our efforts and other unforeseen events, our plans and priorities may change and we may apply the net proceeds of this offering in different manners than we currently anticipate. Accordingly, our management will have broad discretion in the timing and application of these net proceeds. Pending application of the net proceeds as described above, we intend to temporarily invest the proceeds in short-term, interest-bearing instruments.

DILUTION

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

The net tangible book value of our common stock as of March 31, 2020 was approximately $11.0 million, or approximately $0.11 per share. Net tangible book value per share represents the amount of our total assets, excluding goodwill and intangible assets, less total liabilities, divided by the total number of our common stock outstanding. Dilution per share to new investors represents the difference between the amount per share paid by new investors for each share in this offering and the net tangible book value per share immediately following the completion of this offering.

After giving effect to the sale of our common stock in the aggregate amount of $40.0 million at an assumed offering price of $1.58 per share, the last reported sale price of our common stock on June 1, 2020 on the Nasdaq Capital Market, and after deducting estimated commissions and estimated offering expenses, our as-adjusted net tangible book value as of March 31, 2020 would have been approximately $49.8 million, or approximately $0.40 per share. This represents an immediate increase in net tangible book value of approximately $0.29 per share to our existing shareholders and an immediate dilution in as-adjusted net tangible book value of approximately $1.18 per share to new investors of our common stock in this offering, as illustrated by the following table:

The table above assumes for illustrative purposes that an aggregate of 25,316,455 of our common stock are sold during the term of the sales agreement with Jefferies at a price of $1.58 per share, the last reported sale price of our common stock on the Nasdaq Capital Market on June 1, 2020, for aggregate net proceeds of approximately $38.84 million, after deducting commissions and estimated aggregate offering expenses payable by us. The as adjusted information is illustrative only and will adjust based on the actual price to the public, the actual number of shares sold and other terms of the offering determined at the time our common stock are sold pursuant to this prospectus. The shares pursuant to the sales agreement with Jefferies are being sold from time to time at various prices. An increase of $1.00 per share in the price at which the shares are sold from the assumed offering price of $1.58 per share shown in the table above, assuming all of our common stock in the aggregate amount of $40.0 million during the term of the sales agreement with Jefferies is sold at that price, would decrease our as adjusted net tangible book value per share after the offering to $0.59 per share and would increase the dilution in net tangible book value per share to new investors in this offering to $1.99 per share, after deducting commissions and estimated aggregate offering expenses payable by us. A decrease of $1.00 per share in the price at which the shares are sold from the assumed offering price of $1.58 per share shown in the table above, assuming all of our common stock in the aggregate amount of $40.0 million during the term of the sales agreement with Jefferies is sold at that price, would decrease our as adjusted net tangible book value per share after the offering to $0.20 per share and would decrease the dilution in net tangible book value per share to new investors in this offering to $0.38 per share, after deducting commissions and estimated aggregate offering expenses payable by us. This information is supplied for illustrative purposes only.

To the extent that any options have been or are exercised, preferred shares are converted, new options are issued under our equity incentive plans or we otherwise issue additional common stock in the future, there will be further dilution to new investors. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our shareholders.

PLAN OF DISTRIBUTION

We have entered into a sales agreement with Jefferies under which we may offer and sell up to $40.0 million of our shares of common stock from time to time through Jefferies, acting as agent. Sales of our shares of common stock, if any, under this prospectus supplement and the accompanying prospectus will be made by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act.

Each time we wish to issue and sell shares of common stock under the sales agreement, we will notify Jefferies of the number of shares to be issued, the dates on which such sales are anticipated to be made, any limitation on the number of shares to be sold in any one day and any minimum price below which sales may not be made. Once we have so instructed Jefferies, unless Jefferies declines to accept the terms of such notice, Jefferies has agreed to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such shares up to the amount specified on such terms. The obligations of Jefferies under the sales agreement to sell our shares of common stock are subject to a number of conditions that we must meet.

The settlement of sales of shares between us and Jefferies is generally anticipated to occur on the second trading day following the date on which the sale was made. Sales of our shares of common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and Jefferies may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

We will pay Jefferies a commission equal to 3.0% of the aggregate gross proceeds we receive from each sale of our shares of common stock. 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. In addition, we have agreed to reimburse Jefferies for the fees and disbursements of its counsel, payable upon execution of the sales agreement, in an amount not to exceed $50,000, in addition to certain ongoing disbursements of its legal counsel. We estimate that the total expenses for the offering, excluding any commissions or expense reimbursement payable to Jefferies under the terms of the sales agreement, will be approximately $1.2 million. The remaining sale proceeds, after deducting any other transaction fees, will equal our net proceeds from the sale of such shares.

Jefferies will provide written confirmation to us before the open on the Nasdaq Capital Market on the day following each day on which shares of common stock are sold under the sales agreement. Each confirmation will include the number of shares sold on that day, the corresponding sales price and the issuance price payable to us.

In connection with the sale of the shares of common stock on our behalf, Jefferies will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation of Jefferies will be deemed to be underwriting commissions or discounts. We have agreed to indemnify Jefferies against certain civil liabilities, including liabilities under the Securities Act. We have also agreed to contribute to payments Jefferies may be required to make in respect of such liabilities.

The offering of our shares of common stock pursuant to the sales agreement will terminate upon the earlier of (i) the sale of all shares of common stock subject to the sales agreement and (ii) the termination of the sales agreement as permitted therein.

This summary of the material provisions of the sales agreement does not purport to be a complete statement of its terms and conditions. A copy of the sales agreement is filed as an exhibit to the registration statement of which this prospectus supplement forms a part.

Jefferies and its affiliates may in the future provide various investment banking, commercial banking, financial advisory and other financial services for us and our affiliates, for which services they may in the future receive customary fees. In the course of its business, Jefferies may actively trade our securities for its own account or for the accounts of customers, and, accordingly, Jefferies may at any time hold long or short positions in such securities.

A prospectus supplement and the accompanying prospectus in electronic format may be made available on a website maintained by Jefferies, and Jefferies may distribute the prospectus supplement and the accompanying prospectus electronically.

ITEM 14. Other Expenses of Issuance and Distribution

The following table sets forth expenses payable by us in connection with the issuance and distribution of the securities being registered pursuant to this registration statement. All the amounts shown are estimates except for the SEC registration fee.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

We are incorporated under the laws of the State of Delaware. Section 145 of the Delaware General Corporation Law provides that a Delaware corporation may indemnify any persons who are, or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person was an officer, director, employee or agent of such corporation, or is or was serving at the request of such person as an officer, director, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was illegal. A Delaware corporation may indemnify any persons who are, or are threatened to be made, a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit provided such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director has actually and reasonably incurred. Our certificate of incorporation and bylaws provide for the indemnification of our directors and officers to the fullest extent permitted under the Delaware General Corporation Law.

Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duties as a director, except for liability for any:

Our certificate of incorporation includes such a provision. Expenses incurred by any officer or director in defending any such action, suit or proceeding in advance of its final disposition shall be paid by us upon delivery to us of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified by us.
