Overview

We are a molecular diagnostic company focused on developing and commercializing proprietary laboratory-developed tests (“LDTs”) to serve unmet medical needs across the cancer care continuum. Our tests aim to provide actionable information to physicians and patients at critical decision points to optimize diagnosis and treatment decisions, improve patient outcomes, and reduce overall cost of care. We have prioritized lung cancer as our first indication. Lung cancer remains the leading cause of cancer death in the United States, despite the availability of molecular testing and novel therapies to treat patients.

Through strategic asset and business acquisitions during 2019 and early 2020, we have gone through a transformation from a single product company to a company with a wider battery of laboratory-developed tests that physicians may use at different critical decision points in cancer diagnosis and treatment to support their decision-making. We believe that our effort to provide particular tests for certain key decision points along the continuum of diagnosis shown below will mitigate the inherent risk of being a single product company and should lead to greater revenue opportunities in rapidly emerging markets in lung cancer and beyond.

Corporate Information

We were incorporated in 2009 in the state of California and were formerly a majority-owned subsidiary of Lineage Cell Therapeutics, Inc. (formerly known as BioTime, Inc.) (“Lineage”), a publicly traded, clinical-stage, biotechnology company developing new cellular therapies for degenerative retinal diseases, neurological conditions associated with demyelination, and aiding the body in detecting and combating cancer. Since February 17, 2017, we ceased to be a subsidiary of Lineage for financial reporting purposes when Lineage’s percentage ownership of our outstanding common stock declined below 50% and, as of the date of this prospectus supplement, because Lineage’s ownership interest in our common stock has decreased to below 10%, Lineage no longer exercises significant influence over our operations and management. However, we may still be considered an affiliate of Lineage. Our principal executive offices are located at 15 Cushing, Irvine, California 92618. Our telephone number is (949) 409-7600. Our website is www.oncocyte.com. Information contained on, or that can be accessed through, our website, is not, and shall not be deemed to be, incorporated in this prospectus supplement or considered a part thereof.

THE OFFERING

(1) The number of shares of our common stock to be outstanding immediately after this offering as shown above is based on 67,217,906 shares of our common stock outstanding and excludes:

RISK FACTORS

Investing in our securities involves a high degree of risk and uncertainty. You should carefully consider these risk factors, together with all of the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, as modified and superseded, before you decide to invest in our securities, including without limitation the risk factors listed under Part I, Item 1A. Risk Factors of our Annual Report on Form 10-K, as filed with the SEC on March 26, 2020 (the “Annual Report”) and in our Quarterly Reports on Form 10-Q filed with the SEC. The occurrence of any of the following risks could harm our business. In that case, the trading price of our common stock could decline, and you may lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our operations. You should also refer to the other information contained in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus, including our financial statements and the notes to those statements and the information set forth in the section entitled “Special Note Regarding Forward-Looking Statements.”

Risks Related to this Offering

Because our management will have broad discretion and flexibility in how the net proceeds from this offering are used, our management may use the net proceeds in ways with which you disagree or which may not prove effective.

We currently intend to use the net proceeds from this offering primarily to support our DetermaRx™ and DetermaDx™, and Insight Assays development and commercialization efforts, including additional clinical studies to support reimbursement and adoption, to initiate future product development, and for general corporate and working capital purposes. In addition, as part of our strategic business plan, we regularly research and are actively evaluating the acquisition of businesses or technologies that we believe are complementary to our own product development and commercialization efforts. Consequently, we may use net proceeds from the offering to invest in or acquire businesses or assets, including also licensing of rights to use technologies. However, we have no binding agreements with respect to any such strategic transactions or acquisitions in place as of the date of this prospectus supplement, other than to fully acquire Razor upon the meeting of certain milestones and contingent considerations to be paid to Razor and Insight, as previously disclosed.

We have not allocated specific amounts of the net proceeds from this offering for any of the foregoing purposes. Accordingly, our management will have broad discretion and flexibility in applying the net proceeds of this offering. You will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately

There may be future sales or other dilution of our equity, which may adversely affect the market price of our common stock.

Subject to the equity distribution agreement, dated March 20, 2020 (the “ATM Agreement”), between us and Piper Sandler & Co. (the “Agent”) to create an at-the-market equity program, we are generally not restricted from issuing additional common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock. We may, in the future, seek additional capital through a combination of public and private offerings of common stock, or other securities convertible into or exchangeable for, or that represent a right to receive, common stock. We may also participate in debt financings. To the extent that we raise additional capital through the sale of common stock, or securities that are convertible into or exchangeable for, or that represent a right to receive, common stock, your ownership interest will be diluted, and the market price of our common stock could be adversely affected. The incurrence of indebtedness, if obtained, would result in increased fixed payment obligations and could involve restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Moreover, we will issue additional shares of our common stock upon the exercise of currently outstanding options warrants. Such issuances may involve a significant number of our common shares at prices less than the offering price in this offering.

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

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

Because the purchase price per share of common stock in this offering is substantially higher than the net tangible book value per share of our common stock outstanding prior to this offering, investors in this offering will suffer immediate and substantial dilution in the net tangible book value per share of common stock. Based on the public offering price of $2.27 per share in this offering, if you purchase securities in this offering, you will suffer immediate and substantial dilution of approximately $1.60 per share in net tangible book value of our common stock. See “Dilution” on page S-18 of this prospectus supplement for a more detailed discussion of the dilution you will incur in connection with this offering.

Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain.

We have never declared or paid cash dividends on our capital stock and we do not anticipate paying cash dividends in the foreseeable future. We currently intend to retain all of our future earnings, if any, but for reinvestment in our business. Any future determination to pay cash dividends will be at the discretion of our board of directors and will be dependent upon the repayment of loans under an existing credit agreement with Silicon Valley Bank, our financial condition, results of operations, capital requirements and other factors as our board of directors deems relevant. See “Dividend Policy” on page S-17 of this prospectus supplement. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

Risks Related to Our Business

We may incur significant cash payment and common stock issuance obligations under our agreements arising from our investments in Razor and Insight.

As described in Note 5 to our financial statements included in our Annual Report, we have entered into certain agreements with Razor and its shareholders, including a Subscription and Stock Purchase Agreement (the “Razor Purchase Agreement”), Minority Holder Stock Purchase Agreements (the “Minority Purchase Agreements”), and a Development Agreement (the “Development Agreement”), under which we may incur significant cash payment and common stock issuance obligations. Under the Razor Purchase Agreement and the Minority Holder Stock Purchase Agreements we could become obligated to purchase, or we may elect to purchase, the outstanding Razor common stock from its shareholders for which we would pay those shareholders $10 million in cash and issue to them shares of our common stock with an aggregate market value equal to $5 million at the date of issue.

Under the Development Agreement, upon completion of enrollment of the full number of patients for a clinical trial of DetermaRx™ for purposes of promoting commercialization (the “Clinical Trial”), we will be obligated to issue to the Razor shareholders shares of our common stock with an aggregate market value equal to $3 million at the date of issue.

The number of shares of our common stock issuable under the Razor Purchase Agreement, the Minority Holder Purchase Agreements, and the Development Agreement on a combined basis is limited to 19.99% of the issued and outstanding shares of our common stock or the outstanding voting power of our shares as of the date of the Razor Purchase Agreement, and if that number of shares has a value of less than $5 million on the date the Razor Purchase Agreement and Minority Holder Purchase Agreement obligations must be met, or less than $3 million on the date the Development Agreement obligation must be met, we would need to pay an amount of cash necessary to bring the combined value of cash and shares to $5 million to satisfy the Razor Purchase Agreement and Minority Holder Purchase Agreement obligations, or $3 million to satisfy the Development Agreement obligation. The number of shares that may become issuable to satisfy those $5 million and $3 million obligations cannot presently be determined because the number of shares will depend upon the market price of our common stock when the shares become issuable. The issuance of those shares of common stock will dilute the interests of our other common stockholders.

Under the Development Agreement we are also obligated to pay the expenses of DetermaRx™ Clinical Trial after Razor’s $4 million “Clinical Trial Expense Reserve” has been exhausted. If within a specified time frame Razor’s principal shareholder Encore Clinical, Inc. (“Encore”) is substantially responsible for obtaining funding to us or Razor for the Clinical Trial from any third-party pharmaceutical company, a portion of such additional funding amount will be paid to Encore, subject to a $3 million cap on the payment to Encore if the funding is provided by a designated pharmaceutical company.

Also, under the Development Agreement we must pay Encore $4 million in cash if Razor receives a final positive coverage decision from Centers for Medicare and Medicaid Services (“CMS”)/Molecular Diagnostics Services (“MolDx”) for reimbursement of patient costs of DetermaRx™.

In addition, under the merger agreement pursuant to which we acquired Insight, as described in Note 11 to the financial statements included in the Annual Report, we have agreed to pay contingent consideration of up to $6.0 million in any combination of cash or shares of our common stock if certain milestones related to DetermaIO™ are achieved (the “Contingent Consideration”), which consist of (i) a $1.5 million clinical trial completion and data publication milestone, (ii) $3.0 million for an affirmative final local coverage determination from CMS for a specified lung cancer test, and (iii) up to $1.5 million for achieving certain CMS reimbursement milestones.

To meet these various cash payment obligations, we may need to sell additional shares of our common stock or other securities to raise the cash needed, or we may have to divert cash on hand that we would otherwise use for other business and operational purposes which could cause us to delay or reduce activities in the development and commercialization of our cancer tests. Any shares of common stock or other securities we sell to raise cash to meet our cash payment obligations will dilute the interests of our common stockholders.

We may experience delays in conducting the additional validation studies necessary for the commercialization of DetermaDx™, or we may encounter unanticipated results or findings.

We have successfully completed our Clinical Laboratory Improvements Amendment (“CLIA”) Laboratory Validation study of DetermaDx™ and have commenced Clinical Validation “Clinical Validation”). Clinical Validation is the final step prior to commercial launch of a laboratory-developed test (“LDT”), and we are anticipating completion of our Clinical Validation study for DetermaDx™ by the end of the second quarter of 2020. If the Clinical Validation study is completed successfully, we plan to commercialize DetermaDx™ promptly thereafter. However, until we perform the Clinical Validation study, we will not know whether we can successfully complete the development of DetermaDx™. We may not be able to successfully complete this testing for DetermaDx™ or any other test we may develop. While we plan to make DetermaDx^TM commercially available in the second half of 2020, there can be no assurance that there will be no delays in the successful completion of the Clinical Validation study and commercialization of DetermaDx™, due to any number factors some of which may not be within our control. Any delays in the successful completion of the Clinical Validation study for DetermaDx™ could cause us to incur significant additional costs and delay the completion of development and commercial launch of DetermaDx™. We may encounter unanticipated results or finding in the Clinical Validation study showing that our earlier study results may not be predictive of future test results with DetermaDx™. We have performed only limited research and development work for other diagnostic tests, and we have conducted no research and development work outside of cancer. Our Immune System Interrogation approach, which analyzes the immune system’s response to a specific disease, and our technology may not ultimately have application in any other population, and we may be unable to identify any future candidates and tests for any other cancer or any other disease population.

We recently launched our first diagnostic test on the market and have not yet generated any revenues from operations.

We are in the early stages process of the commercial launch of DetermaRx™, and we are working to complete development of DetermaDx^TM and anticipate making it commercially available in the second half 2020. However, we may be unable to complete development of DetermaDx™ in that timeframe or at all. We also need to perform additional development work on DetermaIO^TM before it can be made available for commercial use clinically. Even if we complete development of DetermaDx™ and DetermaIO™, our commercialization arrangements for those tests and DetermaRx™ may not generate revenues in sufficient amounts to meet our operating expenses. Without sufficient diagnostic test sales or licensing fee revenues, we will not be able to operate at a profit, and we will not be able to cover our operating expenses without raising additional capital.

We have limited capital, marketing, and sales resources for the commercialization of our diagnostic tests.

We are building our own marketing and sales capability for our diagnostic tests, and are devoting significant financial and management resources to recruiting, training, and managing our sales force and building a health care regulatory compliance program. However, due to our limited capital resources, we may need to enter into marketing arrangements with other diagnostic companies for one or more of our tests in domestic or foreign markets. Under such marketing arrangements we may license marketing rights to one or more of our diagnostic tests to other diagnostic companies or to one or more joint venture companies that may be formed to market our tests, and we might receive only a royalty on sales or an equity interest in a joint venture company. As a result, our revenues from the sale of our tests through such arrangements may be substantially less than the amount of revenues and gross profits that we might receive if we were to market our tests ourselves.

Sales of our diagnostic tests could be adversely impacted by the reluctance of physicians to adopt the use of our tests and by the availability of competing diagnostic tests.

Physicians and hospitals may be reluctant to try a new diagnostic test due to the high degree of risk associated with the application of new technologies and diagnostic test in the field of human medicine, especially if the new test differs from the current standard of care for detecting cancer in patients. Competing tests for the initial diagnosis, reoccurrence diagnosis and optimal treatment of cancer are being manufactured and marketed by established companies and by other smaller biotechnology companies. In order to compete with other diagnostic tests, particularly any that sell at lower prices, our tests will have to provide medically significant advantages or be more cost effective. Even if we are able to overcome physician reluctance and compete with products that are currently on the market, our competitors may succeed in developing new safer, more accurate or more cost-effective diagnostic tests that could render our diagnostic tests and technologies obsolete or noncompetitive.

If our laboratory facilities become damaged or inoperable, or we are required to vacate any facility, our ability to provide services and pursue our research and development and commercialization efforts may be jeopardized.

We do not have any clinical laboratory facilities outside of our facilities in Brisbane, California, and Nashville, Tennessee. Our facilities and equipment could be harmed or rendered inoperable by natural or man-made disasters, including fire, flooding and power outages, which may render it difficult or impossible for us to perform our tests or provide laboratory services for some period of time. The inability to perform our tests or the backlog of tests that could develop if any of our facilities is inoperable for even a short period of time may result in the loss of customers or harm to our reputation or relationships with key researchers, collaborators, and customers, and we may be unable to regain those customers or repair our reputation in the future. Furthermore, our facilities and the equipment we use to perform our research and development work could be costly and time-consuming to repair or replace.

Additionally, a key component of our research and development process involves using biological samples and the resulting data sets and medical histories, as the basis for our diagnostic test development. In some cases, these samples are difficult to obtain. If the parts of our laboratory facilities where we store these biological samples are damaged or compromised, our ability to pursue our research and development projects, commercialization of our diagnostic tests, as well as our reputation, could be jeopardized. We carry insurance for damage to our property and the disruption of our business, but this insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, if at all.

Further, if our laboratories become inoperable, we may not be able to license or transfer our proprietary technology to a third-party, with established state licensure and CLIA certification under the scope of which our diagnostic tests could be performed following validation and other required procedures, to perform the tests. Even if we find a third-party with such qualifications to perform our tests, such party may not be willing to perform the tests for us on commercially reasonable terms. Moreover, we believe our tests are currently subject to enforcement discretion by the Federal Food and Drug Administration (“FDA”) because we believe the tests currently qualify as LDTs. If, however, we are required to find a third-party laboratory to conduct our testing services, we believe this would change our status and the FDA would consider such tests offered through a third-party to then be a medical device subject to active FDA regulation and enforcement under its in vitro diagnostic authorities. In that case, we may be required to obtain premarket clearance or approval prior to offering our tests, which would be time-consuming and costly and could result in interruptions and delays in our ability to sell or offer our tests.

We may not be able to produce additional cancer diagnostic tests that offer high enough sensitivity to offset the availability of minimally invasive biopsies for some types of cancer, which could impede our development and commercialization of an array of diagnostic tests.

We believe that a significant benefit of DetermaDx™ will be the reduction of unnecessary surgical biopsies to diagnose lung cancer. While lung cancer biopsies involve an invasive surgical procedure, biopsies of some other types of cancer, including breast cancer, often can be performed using less invasive procedures that result in significantly less risk, discomfort, and cost to the patient while providing a diagnostic result that would be as accurate or more accurate than any diagnostic tests we may develop. As a result, physicians and patients may prefer to rely on a non-invasive or minimally invasive biopsy to test for certain cancers rather than use a blood test.

We have incurred operating losses since inception, and we do not know if we will attain profitability.

Since our inception in September 2009, we have incurred operating losses and negative cash flows and we expect to continue to incur losses and negative cash flows in the future. Our net losses for the years ended December 31, 2019 and 2018 were $22.4 million and $15.8 million, respectively, and we had an accumulated deficit of $93.7 million as of December 31, 2019. Since inception, we have financed our operations through sales of our common stock and warrants, loans from Lineage and Lineage affiliates, warrant exercises, a bank loan and sale of Lineage common shares that we hold as marketable equity securities. We do not expect Lineage to provide future financing. There is no assurance that we will be able to obtain any additional financing that we may need, or that any such financing that may become available will be on terms that are favorable to us and our shareholders. Ultimately, our ability to generate sufficient operating revenue to earn a profit depends upon our success in developing and marketing or licensing our diagnostic tests and technology.

The research and development work we are doing is costly, time consuming, and uncertain as to its results.

We incurred research and development expenses amounting to approximately $6.8 million and $6.5 million during years ended December 31, 2019 and 2018, respectively. During the past few years we have devoted substantially all of our research and development efforts to the development of DetermaDx™, but we have recently expanded the focus of our research and development to include DetermaIO™ acquired through our merger with Insight and a clinical trial of DetermaRx™. We also plan to conduct research and development of additional or improved versions of our diagnostic tests. If we are successful in developing a new technology or diagnostic test for additional types of cancer, refinement of the new technology or diagnostic test and definition of the practical applications and limitations of the technology or diagnostic test may take years and require the expenditure of large sums of money. There is no assurance that we will be successful in completing the development of our current diagnostic tests or in developing additional diagnostic tests regardless of the amount of our expenditures.

It is likely that we will need to issue additional equity or debt securities in order to raise additional capital needed to pay our operating expenses until such time as our revenues are sufficient to finance our operating expenses.

If we fail to meet our obligations under license agreements, we may lose our rights to key technologies on which our business depends.

We use certain biomarkers that have been licensed from the Wistar Institute of Anatomy and Biology for DetermaDx™ and we have rights to commercialize DetermaRx™ under a sublicense from Razor. These agreements impose obligations on us, including payment obligations and obligations to pursue development and commercialization of diagnostic tests under the licensed patents and technology. If the licensor believes that we have failed to meet our contractual obligations it could seek to limit or terminate our license rights, which could lead to costly and time-consuming litigation and, potentially, a loss of the licensed rights. During the period of any such litigation our ability to carry out the development and commercialization of DetermaDx™ or DetermaRx™ and any other potential diagnostic tests that utilize licensed markers or other technology, and our ability to raise any capital that we might then need, could be significantly and negatively affected. If our license rights were restricted or ultimately lost, we would not be able to continue to use the licensed biomarkers or technology in our business.

There is a limited number of manufacturers of molecular diagnostic testing equipment and related chemical reagents necessary for the provision of our diagnostic tests.

After encountering inconsistent results using diagnostic testing equipment and reagents from one manufacturer, we switched to diagnostic testing equipment from a different manufacturer. The chemical reagents used with the diagnostic testing equipment are available only from the equipment manufacturer. If issues were to arise with the new equipment or reagents we are using causing us to acquire different diagnostic testing equipment again, we would need to conduct validation and analytic studies to determine whether our previous test results can be reproduced using the new equipment. As a result, we could experience delays again in developing our diagnostic tests. If similar issues were to arise after commercialization of a diagnostic test, we could experience a disruption for a period of time in providing the diagnostic tests to patients and we would lose revenues and potentially market share as a result.

If we fail to enter into and maintain successful strategic alliances for diagnostic tests that we elect to co-develop, co-market, or out-license, we may have to reduce or delay our diagnostic test development or increase our expenditures.

In order to facilitate the development, manufacture and commercialization of our diagnostic tests we may enter into strategic alliances with diagnostic, pharmaceutical, or medical device companies to advance our programs and enable us to maintain our financial and operational capacity. We will face significant competition in seeking appropriate alliances. We may not be able to negotiate alliances on acceptable terms, if at all. If we fail to create and maintain suitable alliances, we may have to limit the size or scope of, or delay, one or more of our product development or research programs, or we will have to increase our expenditures and will need to obtain additional funding, which may be unavailable or available only on unfavorable terms.

If we are able to enter into development and marketing arrangements with diagnostic, pharmaceutical or medical device companies for our diagnostic tests, we may license product development, manufacturing, and marketing rights to the pharmaceutical or medical device company or to a joint venture company formed with the pharmaceutical or medical device company. Under such arrangements we might receive only a royalty on sales of the diagnostic tests developed or an equity interest in a joint venture company that develops the diagnostic test. As a result, our revenues from the sale of those diagnostic tests may be substantially less than the amount of revenues and gross profits that we might receive if we were to develop, manufacture, and market the diagnostic tests ourselves.

We may become dependent on possible future collaborations to develop and commercialize many of our diagnostic test candidates and to provide the manufacturing, regulatory compliance, sales, marketing and distribution capabilities required for the success of our business.

We may enter into various kinds of collaborative research and development, manufacturing, and diagnostic test marketing agreements to develop and commercialize our diagnostic tests. Any future milestone payments and cost reimbursements from collaboration agreements could provide an important source of financing for our research and development programs, thereby facilitating the application of our technology to the development and commercialization of our diagnostic tests, but there are risks associated with entering into collaboration arrangements.

There is a risk that we could become dependent upon one or more collaborative arrangements for diagnostic test development or manufacturing or as a source of revenues from the sale of any diagnostic tests that may be developed by us alone or through one of the collaborative arrangements. A collaborative arrangement upon which we might depend might be terminated by our collaboration partner or they might determine not to actively pursue the development or commercialization of our diagnostic tests. A collaboration partner also may not be precluded from independently pursuing competing diagnostic tests or technologies.

There is a risk that a collaboration partner might fail to perform its obligations under the collaborative arrangements or may be slow in performing its obligations. In addition, a collaboration partner may experience financial difficulties at any time that could prevent it from having available funds to contribute to the collaboration. If a collaboration partner fails to conduct its diagnostic test development, manufacturing, commercialization, regulatory compliance, sales and marketing or distribution activities successfully and in a timely manner, or if it terminates or materially modifies its agreements with us, the development and commercialization of one or more diagnostic test candidates could be delayed, curtailed or terminated because we may not have sufficient financial resources or capabilities to continue diagnostic test development, manufacturing, and commercialization on our own.

Failure to adequately protect, or disputes relating to, trademarks, could harm our business.

We cannot be certain that the legal steps we are taking are sufficient to protect our trademark rights or that, notwithstanding legal protection, others will not infringe or misappropriate our intellectual property rights. In addition, we could come into conflict with third parties over trademark rights, which could result in disruptive and expensive litigation. Challenges to our trademarks could result in significant costs related to the prosecution or defense of the registrations of our trademarks or rebranding if we need to abandon or modify a trademark.

Our business could be adversely affected if we lose the services of the key personnel upon whom we depend.

We presently rely on a small senior management team to direct our diagnostics program and our initial commercial activities. Accordingly, the loss of the services of one or more of the members of that management team could have a material adverse effect on our business.

We have granted a security interest in substantially all of our assets to secure our obligations under a bank loan agreement.

We have entered into a Loan and Security Agreement, as amended (the “Loan and Security Agreement”) with Silicon Valley Bank for a loan that is secured by substantially all of our assets, other than our patents and trade secrets, as collateral for the loan. If a default were to arise under the Loan and Security Agreement, the bank could foreclose on its security interest and we could lose our collateral, which could force us to discontinue our operations.

Our business and operations could suffer in the event of system failures.

Despite the implementation of security measures, our internal computer systems and those of our contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Such events could cause interruption of our operations. For example, the loss of data for our diagnostic test candidates could result in delays in our regulatory filings and development efforts and significantly increase our costs. To the extent that any disruption or security breach was to result in a loss of or damage to our data, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the development of our diagnostic test candidates could be delayed.

Security breaches and other disruptions could compromise our information and expose us to liability, and could cause our business and reputation to suffer.

In the ordinary course of business, we collect and store sensitive data, including intellectual property, our proprietary business information and that of our business partners, and personally identifiable information of patients and employees. The secure processing, maintenance, and transmission of this information is critical to our operations and business strategy. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance, or other disruptions. Any such breach could compromise our networks and the information stored there could be accessed, publicly disclosed, lost, or stolen. Any such access, disclosure, theft, or other loss of information could result in legal claims or proceedings or liability under laws that protect the privacy of personal information, and could disrupt our operations and damage our reputation. Even if we do not incur an interruption of or our operations, fines, penalties, or financial liability to third parties from a security breach, we could suffer a loss of confidence in our services, which could adversely affect our business and competitive position.

Failure of our internal control over financial reporting could harm our business and financial results.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting for external purposes in accordance with accounting principles generally accepted in the U.S. Internal control over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect our transactions; providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements; providing reasonable assurance that receipts and expenditures of our assets are made in accordance with management authorization; and providing reasonable assurance that unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected. Our growth and entry into new diagnostic tests, technologies and markets will place significant additional pressure on our system of internal control over financial reporting. Any failure to maintain an effective system of internal control over financial reporting could limit our ability to report our financial results accurately and timely or to detect and prevent fraud. Because we are an emerging growth company and a smaller reporting issuer, we are exempt from the requirement of having our internal controls over financial reporting audited by our independent registered public accountants, which means that material weaknesses or significant deficiencies in our internal controls that might be detected by an audit may not be detected and remedied.

We may from time to time be involved in or subject to legal proceedings, and unfavorable outcomes of such legal proceedings may adversely affect our business and financial condition.

We may from time to time be involved in, subject to, or threatened with legal proceedings related to, or incidental to the conduct of, our business. Such legal proceedings can be complex, costly, and disruptive to business operations by diverting the attention and energies of management and other key personnel. In addition, defense and settlement costs for any legal proceeding can be substantial, even with respect to claims that have no merit.

Our business may be materially adversely affected by the recent coronavirus (COVID-19) outbreak.

The outbreak of the coronavirus (COVID-19) could disrupt our operations due to absenteeism by infected or ill members of management or other employees, or absenteeism by members of management and other employees who elect not to come to work due to the illness affecting others in our office or laboratory facilities, or due to quarantines. COVID-19 illness could also impact members of our Board of Directors resulting in absenteeism from meetings of the directors or committees of directors, and making it more difficult to convene the quorums of the full Board of Directors or its committees needed to conduct meetings for the management of our affairs.

Supplies of chemical reagents used in our diagnostic and research laboratories could be disrupted if the manufacturers or suppliers of the reagents or chemicals used in the reagents experience absenteeism due to illness of their employees or due to local quarantines. Absenteeism due to coronavirus illness could also impact companies that the reagent manufacturers use to ship reagents to us. We cannot presently predict the extent to which the virus may impact our operations.

We are expecting a final local coverage decision from CMS/MolDx for reimbursement of patient costs of DetermaRx™ but it is possible that the timing of that decision could be delayed due to absenteeism by CMS employees or by the diversion of their efforts and attention to reimbursement approval of new diagnostic tests or other activities related to COVID-19. Further, the regulatory framework governing private laboratories and molecular diagnostic companies may be affected as governmental authorities respond to the COVID-19 outbreak, which may have unanticipated and unforeseen impact on our operations.

The broad range of local, state and national responses to COVID-19 has required us to adjust our marketing and selling activities to reflect the current environment. We have adjusted our meetings with the oncology community to rely on non-personal contacts, which might be less effective than in person meetings to promote the use of our tests. Also, the concern over available hospital, staffing, equipment, and other resources, and the risk of exposure to the virus, may lead to early stage lung cancer surgeries being delayed in the current period of uncertainty, which could result in delayed or reduced use of DetermaRx™ in the near term.

The anticipated economic consequences of the COVID-19 pandemic have adversely impacted financial markets, resulting in high share price volatility, reduced market liquidity, and substantial declines in the market prices of the shares of most publicly traded companies, including us. Volatile or declining markets for equities could adversely affect our ability to raise capital when needed through the sale of shares of common stock or other equity securities. While these market conditions persist when we need to raise capital, and if we are able to sell shares of our common stock under then prevailing market conditions, we might have to accept lower prices for our shares and issue a larger number of shares than might have been the case under better market conditions, resulting in significant dilution of the interests of our shareholders.

If we are deemed to be an investment company, we may have to institute burdensome compliance requirements and our activities may be restricted.

An entity that, among other things, is or holds itself out as being engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting, owning, trading, or holding certain types of securities would be deemed an investment company under the Investment Company Act of 1940 (the “1940 Act”). Based on the securities we hold, including our equity ownership in a privately held company, we may not meet requirements for an exemption promulgated under the 1940 Act. If we are deemed to be an investment company under the 1940 Act, we would be subject to additional limitations on operating our business including limitations on the issuance of securities, which may make it difficult for us to raise capital.

USE OF PROCEEDS

We expect to receive net proceed proceeds from this offering of approximately $10.65 million, after deducting the expenses of this offering payable by us (estimated to be $100,000).

We currently intend to use the net proceeds from this offering primarily to support the DetermaRx™ and DetermaDx™, and Insight Assays development and commercialization efforts and additional clinical studies to support reimbursement and adoption, to initiate future product development, and for general corporate and working capital purposes. Additionally, as part of our strategic business plan, we regularly research and evaluate the acquisition of businesses or technologies that we believe are complementary to our own product development and commercialization efforts. Consequently, we may use net proceeds from the offering to invest in or acquire businesses or assets, including also licensing rights to use technologies. Our strategic initiatives are currently focused on, and we are actively evaluating, businesses or technologies that we believe will allow us to acquire additional cancer tests for development. However, we have no binding agreements with respect to any such acquisitions in place as of the date of this prospectus supplement other than our previously disclosed agreement to fully acquire Razor upon the meeting of certain milestones and contingent considerations to be paid to Razor and Insight. We have broad discretion in determining how the proceeds of this offering will be used, and our discretion is not limited by the aforementioned possible uses. You will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. Our board of directors believes the flexibility in application of the net proceeds is prudent.

We have not determined the exact amounts we plan to spend on any of the purposes listed above or the timing of these expenditures. The amounts and timing of our actual expenditures may vary significantly depending on numerous factors, including the actual net proceeds from this offering, the progress of our development and commercialization efforts, the results of our clinical studies, and any unforeseen cash needs. As a result, our management will have broad discretion to allocate the net proceeds from this offering.

Pending application of the net proceeds as described above, we may temporarily invest any net proceeds in a variety of capital preservation instruments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities.

DIVIDEND POLICY

We have never paid cash dividends on our capital stock and we do not anticipate paying cash dividends in the foreseeable future, but intend to retain our capital resources for reinvestment in our business. Under an existing credit agreement with Silicon Valley Bank, we have agreed not to pay dividends or to make any distributions or to redeem to repurchase any capital stock without Silicon Valley Bank’s prior written consent. Any future determination to pay cash dividends will be at the discretion of our board of directors and will be dependent upon the repayment of the loans from Silicon Valley Bank, our financial condition, results of operations, capital requirements and other factors as our board of directors deems relevant.

DILUTION

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

Our net tangible book value as of December 31, 2019 was approximately $30.8 million, or $0.54 per share. Our net tangible book value is the amount of our total tangible assets less our total liabilities. Net tangible book value per share represents net tangible book value divided by the total number of shares of our common stock outstanding as of December 31, 2019.

After giving effect to the issuance and sale of 4,733,700 shares of common stock in this offering at the public offering price of $2.27 per share, after deducting the estimated offering expenses payable by us, the as adjusted net tangible book value as of December 31, 2019 would have been approximately $41.5 million, or $0.67 per share. This represents an immediate increase in net tangible book value of approximately $0.13 per share to our existing shareholders and an immediate dilution in as-adjusted net tangible book value of approximately $1.60 per share to purchasers of our securities in this offering. We determine dilution per share to investors participating in this offering by subtracting as adjusted net tangible book value per share after this offering from the assumed public offering price per share paid by investors participating in this offering.

The following table illustrates this dilution:

The above discussion and table are based on 57,031,654 shares of our common stock outstanding as of December 31, 2019, and excludes:

To the extent that any outstanding options or warrants are exercised, new options, restricted stock or restricted stock units are issued under our equity incentive plan, shares of common stock are sold under our employee stock purchase plan or we otherwise issue additional shares of common stock or other equity or convertible debt securities in the future, you will experience further dilution.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS

The following discussion is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the purchase, ownership and disposition of our common stock issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed herein. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended, or the Code, Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service, or the IRS, in each case, in effect as of the date of this prospectus supplement. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-U.S. Holder of our common stock. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance that the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of our common stock. Tax reforms in the United States may result in significant changes in the rules governing U.S. federal income taxation. Such changes may affect the U.S. federal tax consequences of the purchase, ownership and disposition of the common stock discussed herein.

This discussion is limited to Non-U.S. Holders that hold our common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to Non-U.S. Holders subject to special rules, including, without limitation:

If an entity treated as a partnership for U.S. federal income tax purposes holds our common stock, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding our common stock and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

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

Definition of a Non-U.S. Holder

For purposes of this discussion, a “Non-U.S. Holder” is any beneficial owner of our common stock that is neither a “U.S. person” nor an entity treated as a partnership for U.S. federal income tax purposes. A U.S. person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:

Distributions

As discussed under “Dividend Policy” above, we do not anticipate declaring or paying dividends to holders of our common stock in the foreseeable future. However, if we make distributions of cash or property on our common stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder’s adjusted tax basis in its common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under “Sale or Other Taxable Disposition.”

Subject to the discussion below on effectively connected income, dividends paid to a Non-U.S. Holder of our common stock will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. Holder that is a corporation for U.S. federal income tax purposes also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Sale or Other Taxable Disposition

A Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other taxable disposition of our common stock unless:

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

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

With respect to the third bullet point above, we believe we currently are not, and do not anticipate becoming, a USRPHC. However, there can be no assurance that we currently are not a USRPHC or will not become one in the future. Even if we are or were to become a USRPHC, gain arising from the sale or other taxable disposition by a Non-U.S. Holder of our common stock will not be subject to U.S. federal income tax if our common stock is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market, and such Non-U.S. Holder owned, actually and constructively, 5% or less of our common stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the Non-U.S. Holder’s holding period.

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

Information Reporting and Backup Withholding

Payments of dividends on our common stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on our common stock paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our common stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person, or the holder otherwise establishes an exemption. Proceeds of a disposition of our common stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

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

Additional Withholding Tax on Payments Made to Foreign Accounts

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

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our common stock, and to payments of gross proceeds from the sale or other disposition of such stock. Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our common stock.

TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission, or the SEC, under the Securities Act, using a “shelf” registration process. Under this process, we may, from time to time, offer and sell, either individually or in combination, in one or more offerings, up to a total dollar amount of $100.0 million of any of the securities described in this prospectus. In addition, the Selling Shareholders may, from time to time, sell up to an aggregate of 25,539,309 shares of our common stock consisting of (i) 22,775,656 shares of our common stock held by the Selling Shareholders, and (ii) 2,763,653 shares of our common stock issuable upon exercise of the Warrants held by the Selling Shareholders, in one or more transactions as described in this prospectus.

This prospectus provides a general description of the securities we or the Selling Shareholders may offer. Each time we or the Selling Shareholders offer and sell securities under this prospectus, we or the selling shareholders will provide a prospectus supplement that will contain specific information about the terms of that offering. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to a particular offering. The prospectus supplement and any related free writing prospectus may also add, update or change information contained in this prospectus or in any documents that we have incorporated by reference into this prospectus with respect to that offering. To the extent there is a conflict between any statement contained in this prospectus, any applicable prospectus supplement, any related free writing prospectus or any document incorporated by reference into this prospectus, the statement in the document having the later date modifies or supersedes the earlier statement.

The information appearing in this prospectus, any applicable prospectus supplement or any related free writing prospectus is accurate only as of the date on the front of the document, and any information we have incorporated by reference is accurate only as of the date of the document incorporated by reference, regardless of the time of delivery of this prospectus, any applicable prospectus supplement or any related free writing prospectus, or the time of any sale of a security. Our business, financial condition, results of operations and prospects may have changed since those dates.

You should rely only on the information contained in, or incorporated by reference into, this prospectus and any applicable prospectus supplement, or the information contained in any free writing prospectus we have authorized for use in connection with a specific offering. Neither we nor the Selling Shareholders have authorized anyone to provide you with different or additional information. This prospectus is neither an offer to sell nor a solicitation of an offer to buy any securities other than those registered by this prospectus, nor is it an offer to sell or a solicitation of an offer to buy securities where an offer or solicitation would be unlawful.

As permitted by SEC rules and regulations, the registration statement of which this prospectus forms a part includes additional information not contained in this prospectus. This prospectus also contains summaries of certain provisions of the documents described herein, but all summaries are qualified in their entirety by reference to the actual documents. You may read the registration statement and the other reports we file with the SEC, and you may obtain copies of the actual documents summarized herein (if and when filed with the SEC), at the SEC’s website. See “Where You Can Find More Information.”

Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

SUMMARY

This summary highlights selected information contained elsewhere in this prospectus. This summary is not complete and does not contain all the information you should consider before investing in our securities pursuant to this prospectus. Before making an investment decision, please carefully read this entire prospectus and the documents incorporated by reference into this prospectus, including the “Risk Factors” section of this prospectus and our financial statements and the related notes incorporated by reference into this prospectus. In this prospectus, unless the context otherwise requires, the terms “OncoCyte,” “we,” “us” or “our” refer to OncoCyte Corporation.

Overview

Our mission is to develop highly accurate, easy to administer, non-invasive molecular diagnostic tests to improve the standard of care for cancer diagnosis by better meeting the needs of patients, physicians and payers. Our current focus is developing DetermaVu™, a non-invasive molecular lung cancer confirmatory diagnostic that can be administered to patients as a blood test. DetermaVu™ utilizes proprietary sets of gene expression markers to help confirm whether suspicious lung nodules detected through Low Dose Computed Tomography, or LDCT, scans, x-rays or other imaging are likely to be benign or malignant.

Molecular diagnostics such as DetermaVu™ are assays that identify a disease by studying molecules such as proteins, deoxyribonucleic acid, or DNA, and ribonucleic acid, or RNA, in a tissue or fluid. DetermaVu™ is based on our proprietary Immune System Interrogation approach that examines the body’s immune system response to a specific disease by measuring differential RNA expression in patients with the disease versus patients without the disease. In the future, we may study whether our technology and Immune System Interrogation approach could have applications in other types of cancer or other diseases.

In January 2019 we completed an R&D Validation study of DetermaVu™ that demonstrated the accuracy of the DetermaVu™ assay in detecting lung cancer. The R&D Validation study demonstrated a sensitivity of 90% (95% CI 82%-95%) and specificity of 75% (95% CI 68%-81%) of DetermaVu™ on a prospectively collected cohort of 250 patient blood samples that were blinded to laboratory operators. Sensitivity is the percentage of malignant nodules that are correctly identified and specificity is the percentage of benign nodules correctly identified with correct identification in our study confirmed by biopsy results or serial imaging. A 95% confidence interval or “CI” suggests that there is a 95% chance that final test performance will be within the stated range. Notably, we obtained these results without including any clinical factors such as nodule size in our proprietary DetermaVu™ algorithm.

In April 2019, we successfully completed an Analytic Validation study and commenced a CLIA Validation study. The Analytic Validation Study involved a series of studies, as specified in guidelines for labs under the Clinical Laboratory Improvement Amendments of 1988, or CLIA, designed to establish the performance characteristics of the ThermoFisher Next Generation Sequencing System used for DetermaVu™. The CLIA Validation study currently underway involves assaying approximately 120 samples previously tested in our R&D Validation study in our CLIA validated lab using the assay system now analytically validated, with the goal of demonstrating that the assay system as being run in our CLIA lab provides the same results as those observed in our R&D Validation study.

We have prioritized our efforts on DetermaVu™ and lung cancer because we believe that the early detection of lung cancer is one of the greatest unmet needs in diagnostics. Our scientific approach is to measure the immune system’s response to disease and as such we believe that it may prove promising in other cancers and other disease areas.

RISK FACTORS

Investing in our securities involves a high degree of risk and uncertainty. Before making an investment decision with respect to our securities, we urge you to carefully consider the risks, uncertainties and assumptions described in this prospectus, the applicable prospectus supplement and the documents incorporated by reference herein and therein, including the risks described in the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 2018, as amended by Amendment No. 1 thereto on Form 10-K/A, or the Annual Report, and our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2019, which are incorporated by reference into this prospectus.

In connection with any specific offering, we also expect to provide risk factors and other information in the applicable prospectus supplement.

If one or more of the adverse events relevant to these risks and uncertainties actually occurs, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. This could cause the trading price of our securities to decline, and you could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may have similar adverse effects on us.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents that are incorporated by reference into this prospectus contain or incorporate by reference forward-looking statements within the meaning of applicable securities laws.

There are a number of important factors that could cause our actual results to differ materially from those indicated or implied by forward-looking statements. These important factors include those discussed under the “Risk Factors” sections and elsewhere in our Annual Report and the other periodic reports and other filings that we file from time to time with the SEC. These factors and the other cautionary statements made in this prospectus and the documents incorporated by reference herein should be read as being applicable to all related forward-looking statements whenever they appear in this prospectus. The disclosure in this prospectus, including any forward-looking statement, speaks only as of its date, the date of this prospectus, or the date of any document incorporated by reference into this prospectus, as applicable. We disclaim any intention or obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law.

USE OF PROCEEDS

Except as described in any prospectus supplement in connection with a specific offering, we intend to use the net proceeds from our sale of the securities offered under this prospectus for working capital and general corporate purposes. The principal purposes for which we intend to use the net proceeds from a specific offering and the approximate amounts intended to be used for each such purpose will be set forth in the prospectus supplement relating to that offering.

We will not receive any of the proceeds from the sale of the Resale Shares being offered by the Selling Shareholders, although we may receive proceeds from cash exercises of the Warrants.

DIVIDEND POLICY

We have never paid cash dividends on our capital stock and we do not anticipate paying cash dividends in the foreseeable future, but intend to retain our capital resources for reinvestment in our business. Any future determination to pay cash dividends will be at the discretion of our board of directors and will be dependent upon our financial condition, results of operations, capital requirements, requirements of our then-existing credit agreements and other factors as our board of directors deems relevant.

SECURITIES THAT MAY BE OFFERED

We may offer shares of common stock, shares of preferred stock, warrants, units consisting of a combination of the foregoing securities or any other combination of the foregoing. We may offer up to $100.0 million of securities under this prospectus. The prices and terms of any offering will be determined by market conditions at the time of offering. We may issue preferred stock that is exchangeable for or convertible into common stock or any of the other securities that may be sold under this prospectus. Each time we offer securities under this prospectus, we will provide offerees with a prospectus supplement that will describe the specific amounts, prices and other important terms of the securities being offered.

In addition, the Selling Shareholders may sell up to an aggregate of 25,539,309 shares of our common stock, consisting of shares of our common stock held by the Selling Shareholders and shares of our common stock issuable upon exercise of the Warrants.

The summaries below provide a general description of the securities we and the Selling Shareholders may offer and are not intended to be complete. The particular terms of any security will be described in the applicable prospectus supplement.

DESCRIPTION OF CAPITAL STOCK

The following description of our common stock and preferred stock, together with any additional information we include in any applicable prospectus supplement, documents incorporated by reference or any related free writing prospectus, summarizes the material terms and provisions of our common stock that we and the Selling Shareholders may offer, and the preferred stock that we may offer, under this prospectus. We will describe the particular terms of any class or series of these securities in more detail in the applicable prospectus supplement. The description of our capital stock below is summarized from, and qualified in its entirety by reference to, our articles of incorporation and our bylaws, in each case, as amended and as in effect on the date of this prospectus, each of which has been publicly filed with the SEC. Certain terms of our capital stock described below are also based on the California Corporations Code as in existence on the date of this prospectus, and may be affected by future amendments to such code.

General

Our articles of incorporation currently authorizes the issuance of up to 85,000,000 shares of common stock, no par value, and up to 5,000,000 shares of preferred stock, no par value.

Common Stock

Each holder of record of common stock is entitled to one vote for each outstanding share owned, on every matter properly submitted to the shareholders for their vote.

Subject to any dividend rights of holders of any of the preferred stock that we may issue from time to time, holders of common stock are entitled to any dividend declared by our board of directors out of funds legally available for that purpose.

Subject to the prior payment of any liquidation preference to holders of any preferred stock that we may issue from time to time, holders of common stock are entitled to receive on a pro rata basis all of our remaining assets available for distribution to the holders of common stock in the event of the liquidation, dissolution, or winding up of our operations. Holders of our common stock do not have any preemptive, subscription, or redemption rights. All of the outstanding shares of our common stock are fully paid and non-assessable.

Our common stock is listed on the NYSE American under the symbol “OCX.”

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC, 6201 15th Avenue, Brooklyn, New York 11219.

Preferred Stock

We may issue preferred stock in one or more series, at any time, with such rights, preferences, privileges and restrictions as our board of directors may determine, all without further action of our shareholders. Any series of preferred stock which may be authorized by our board of directors in the future may be senior to and have greater rights and preferences than our common stock. There are no shares of preferred stock presently outstanding and we have no present plan, arrangement, or commitment to issue any preferred stock.

The rights, privileges, preferences and restrictions of any class or series of preferred stock may be subordinated to, pari passu with or senior to any of those of any present or future class or series of preferred stock or common stock. Our board of directors is also expressly authorized to increase or decrease the number of shares of any series subsequent to the issue of that series, but not below the number of shares of such series then outstanding. The issuance of preferred stock may have the effect of decreasing the market price of our common stock and may adversely affect the voting power of holders of our common stock and reduce the likelihood that holders of our common stock will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change in our control or other corporate action.

The particular terms of each class or series of preferred stock that we may offer under this prospectus, including redemption privileges, liquidation preferences, voting rights, dividend rights or conversion rights, will be more fully described in the applicable prospectus supplement relating to the preferred stock offered thereby. The applicable prospectus supplement will specify the terms of the class or series of preferred stock we may offer, including:

DESCRIPTION OF WARRANTS

General

We may offer warrants for the purchase of shares of common stock, shares of preferred stock or the other securities registered hereby, in one or more series. We may issue the warrants by themselves or together with common stock, preferred stock, other warrants or units, and the warrants may be attached to or separate from any offered securities. While the terms we have summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe in particular the terms of any series of warrants that we may offer in more detail in the applicable prospectus supplement and any applicable free writing prospectus. The terms of any warrants offered by a prospectus supplement may differ from the terms described below.

We will file as an exhibit to the registration statement of which this prospectus forms a part, or will incorporate by reference from another report that we file with the SEC, the form of warrant or warrant agreement, which may include a form of warrant certificate, as applicable, that describes the terms of the particular series of warrants we may offer before the issuance of the related series of warrants. We may issue the warrants under a warrant agreement that we will enter into with a warrant agent to be selected by us. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any registered holders of warrants or beneficial owners of warrants. The following summary of material provisions of the warrants and warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the form of warrant or warrant agreement and warrant certificate applicable to a particular series of warrants. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete form of warrant or the warrant agreement and warrant certificate, as applicable, that contain the terms of the warrants.

The particular terms of any issue of warrants will be described in the prospectus supplement relating to the issue. Those terms may include:

Each warrant will entitle its holder to purchase the number of securities at the exercise price set forth in, or calculable as set forth in, the applicable prospectus supplement. The warrants may be exercised as set forth in the prospectus supplement relating to the warrants offered. Unless we otherwise specify in the applicable prospectus supplement, warrants may be exercised at any time up to the close of business on the expiration date set forth in the prospectus supplement relating to the warrants offered thereby. After the close of business on the expiration date, unexercised warrants will become void.

We will specify the place or places where, and the manner in which, warrants may be exercised in the form of warrant, warrant agreement or warrant certificate and applicable prospectus supplement. Upon receipt of payment and the warrant or warrant certificate, as applicable, properly completed and duly executed at the corporate trust office of any warrant agent, or any other office (including ours) indicated in the prospectus supplement, we will, as soon as practicable, issue and deliver the securities purchasable upon such exercise. If less than all of the warrants (or the warrants represented by such warrant certificate) are exercised, a new warrant or a new warrant certificate, as applicable, will be issued for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

Prior to the exercise of any warrants to purchase common stock or preferred stock, holders of the warrants will not have any of the rights of holders of common stock or preferred stock purchasable upon exercise, including the right to vote or to receive any payments of dividends or payments upon our liquidation, dissolution or winding up on the common stock or preferred stock purchasable upon exercise, if any.

DESCRIPTION OF UNITS

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

We will file as an exhibit to the registration statement of which this prospectus forms a part, or will incorporate by reference from another report we file with the SEC, the form of unit agreement that describes the terms of the series of units we may offer under this prospectus, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete unit agreement and any supplemental agreements that contain the terms of the units.

General

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

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

The provisions described in this section, as well as those described in the sections of this prospectus titled “Description of Capital Stock” and “Description of Warrants” will apply to each unit and to any common stock, preferred stock or warrant included in each unit, respectively.

Enforceability of Rights by Holders of Units

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

We and any unit agent (including any of its agents) may treat the registered holder of any unit certificate as an absolute owner of the units evidenced by that certificate for any purpose and as the person entitled to exercise the rights attaching to the units so requested, despite any notice to the contrary.

SELLING SHAREHOLDERS

This prospectus also relates to the offer and resale by the Selling Shareholders of up to 25,539,309 Resale Shares, consisting of (i) 22,775,656 shares of our common stock held by the Selling Shareholders, and (ii) 2,763,653 shares of our common stock issuable upon exercise of the Warrants. The Selling Shareholders may sell any, all or none of the Resale Shares included in and offered by this prospectus. These securities were purchased in various private transactions as summarized below. The summaries do not purport to be complete and, in the case of agreements summarized below, are qualified by reference to the full text of the respective agreements.

BioTime Registration Rights Agreement

In November 2015, we effected a 1-for-2 reverse stock split of our common stock, or the Reverse Stock Split. All share numbers reflected below have been adjusted to give effect to the Reverse Stock Split.

In August 2011, we entered into a Stock Purchase Agreement, or the 2011 Agreement, with BioTime, Inc., or BioTime, pursuant to which we sold and issued 3,500,000 shares of our common stock to BioTime. In May 2015, we entered into a Stock Subscription Agreement, or the May 2015 Agreement, with BioTime pursuant to which we sold and issued 1,500,000 shares of our common stock to BioTime. In September 2015, we entered into another Stock Subscription Agreement, or the September 2015 Agreement, with BioTime pursuant to which we sold and issued 2,710,857 shares of our common stock to BioTime. We refer to the 2011 Agreement, the May 2015 Agreement and the September 2015 Agreement collectively as the Purchase Agreements. In connection with the Purchase Agreements, we entered into a Registration Rights Agreement, first executed in October 2009 and amended in August 2011, May 2015 and November 2015, with BioTime and certain other parties. Pursuant to the Registration Rights Agreement, we agreed, upon the occurrence of certain events and subject to certain conditions, to file with the SEC a registration statement covering the shares of our common stock sold and issued to these parties pursuant to the Purchase Agreements for resale under the Securities Act, and to use commercially reasonable efforts to keep such registration statement effective until the earlier of (i) the completion of the distribution or distributions being made pursuant to such registration statement, or (ii) such time as these parties are eligible to sell such shares of common stock under Rule 144 under the Securities Act without application of the manner of sale and volume limitations thereunder.

We also issued an aggregate of 11,708,094 shares of our common stock to BioTime in private transactions in October 2009, July 2011 and November 2015 and we have agreed to include all outstanding shares of our common stock issued in those transactions in the registration statement of which this prospectus forms a part. In December 2015, BioTime distributed 4,744,707 shares of the 19,418,951 shares of our common stock it then held to its shareholders. The resulting 14,674,244 shares of our common stock held by BioTime constitute the Resale Shares being registered hereby on behalf of BioTime.

August 2016 Private Placement

In August 2016, we sold an aggregate of 3,246,153 immediately separable units, with each unit consisting of one share of our common stock and one warrant to purchase one share of our common stock, at a price of $3.25 per unit. The warrants have an exercise price of $3.25 per share of common stock, became exercisable in October 2016, and may be exercised until October 2021. We refer to this transaction as the “August 2016 Private Placement.” We agreed to register the resale of the securities contained in the units, subject to certain conditions. All of the Resale Shares being registered hereby on behalf of The Bailey 1995 Family Trust and Seamark Fund, L.P. represent shares of our common stock issuable upon exercise of Warrants contained in the units they purchased in the August 2016 Private Placement. The Resale Shares being registered hereby on behalf of Broadwood Partners L.P., or Broadwood, include 1,538,461 shares of our common stock and 573,461 shares of our common stock issuable upon exercise of Warrants contained in the units Broadwood purchased in the August 2016 Private Placement.

February 2017 Warrant Exercise Agreements

In February 2017, we entered into warrant exercise agreements with the following Selling Shareholders, pursuant to which each agreed to cash-exercise warrants acquired in the August 2016 Private Placement and we issued to them new Warrants, in each case immediately exercisable and expiring in February 2022, as follows:

Under the warrant exercise agreement with Broadwood, we agreed to file a registration statement covering the shares issuable upon exercise of the new Warrants, subject to certain conditions. We further agreed to use commercially reasonable efforts to keep such registration statement effective until the earlier of the date that all of shares covered by the registration statement have been sold or can be sold publicly without restriction or limitation under Rule 144, or five years from the date of the warrant exercise agreement. The Resale Shares being registered hereby on behalf of Broadwood include the 212,500 shares of our common stock issuable upon exercise of its new Warrant. We have also agreed to include the shares of our common stock issuable upon exercise of the new Warrants issued to ALB Investments, Phylis Esposito and The Thunen Family Trust in the registration statement of which this prospectus forms a part, which represent all of the Resale Shares being registered hereby on behalf of such holders.

July 2017 Warrant Exercise Agreements

In July 2017, we entered into additional warrant exercise agreements with the following Selling Shareholders, pursuant to which each agreed to cash-exercise warrants acquired in the August 2016 Private Placement and we issued to them new Warrants, in each case immediately exercisable and expiring in July 2019 or July 2022, as follows:

Under the warrant exercise agreement with Broadwood, we agreed to file a registration statement covering the shares issuable upon exercise of the new Warrants, subject to certain conditions. We further agreed to use commercially reasonable efforts to keep such registration statement effective until the earlier of the date that all of shares covered by the registration statement have been sold or can be sold publicly without restriction or limitation under Rule 144, or five years from the date of the warrant exercise agreement. The Resale Shares being registered hereby on behalf of Broadwood include the 270,000 shares of our common stock issuable upon exercise of its new Warrant. We have also agreed to include the shares of our common stock issuable upon exercise of the new Warrants issued to Anthony Low-Beer, Patrick Lin and GKarfunkel in the registration statement of which this prospectus forms a part, which represent all of the Resale Shares being registered hereby on behalf of such holders.

Securities Purchase Agreements

In March 2018, we entered into a securities purchase agreement pursuant to which we sold and issued an aggregate of 3,968,254 shares of our common stock to Broadwood in a private placement. Pursuant to the securities purchase agreement, we also agreed to register the resale of the shares of our common stock sold in the private placement, subject to certain conditions. We also agreed to pay liquidated damages if we did not file the registration statement in a timely manner. Because the registration statement was not filed as required by the securities purchase agreement, during 2019 we paid $300,000 to Broadwood. The Resale Shares being registered hereby on behalf of Broadwood include these 3,968,254 shares of our common stock.

Material Relationships

Prior to February 2017, we were a majority-owned, consolidated subsidiary of BioTime. Since February 2017, the shares of our common stock held by BioTime have accounted for less than 50% of our total common stock outstanding and we ceased being a consolidated subsidiary of BioTime.

In October 2009, we entered into a Shared Facilities and Services Agreement, or Shared Facilities Agreement, with BioTime, pursuant to which we have use of laboratory and office space at BioTime’s facility in Alameda, California. In addition, pursuant to the Shared Facilities Agreement, BioTime has provided, and continues to provide, administrative support to us on a reimbursable basis, and we presently rely on the provision of certain management and administrative services, including patent prosecution, certain legal services, accounting, financial management, and controls over financial accounting and reporting, by BioTime. Further, since our inception, we have partly financed our operations from loans borrowed from BioTime, of which no amount was outstanding as of March 31, 2019, and sales of the common shares of BioTime, of which we held 353,264 shares as marketable equity securities as of March 31, 2019. The chairman of our board of directors currently serves as a member of the board of directors of BioTime, and the chairman of the board of directors of BioTime currently serves as a member of our board of directors.

Neal Bradsher, who may be deemed a beneficial owner of the Resale Shares directly owned by Broadwood, is a member of the board of directors of BioTime.

Don Bailey, who is co-trustee of The Bailey 1995 Family Trust, served as a member of our board of directors from August 2016 until November 2017, and currently serves on the board of directors of BioTime.

Except as described above, and except for the beneficial ownership of the shares of our common stock described in the table below and the Selling Shareholders’ participation in the transactions associated therewith, none of the Selling Shareholders has held any position or office or had any other material relationship with us or any of our predecessors or affiliates within the past three years.

Selling Shareholders Table

The following table and accompanying footnotes, which were prepared based on information furnished to us by or on behalf of each of the Selling Shareholders and information filed with the SEC, sets forth information regarding the beneficial ownership of shares of our common stock owned by the Selling Shareholders as of May 17, 2019. Beneficial ownership is determined in accordance with rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under the rules of the SEC, a person is deemed to be a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment power,” which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of a security if that person has the right to acquire beneficial ownership of such security within 60 days.

The percentage of shares beneficially owned is based on 51,972,830 shares of our common stock issued and outstanding as of May 17, 2019. Shares of our common stock that a Selling Shareholder has the right to acquire within 60 days of the filing date of this prospectus are deemed outstanding for purposes of computing the percentage ownership of such Selling Shareholder’s holdings, but are not deemed outstanding for purposes of computing the percentage ownership of any other Selling Shareholder. The number of shares and percentage of our outstanding common stock to be beneficially owned after completion of this offering assumes that the Selling Shareholders will sell all the Resale Shares offered hereby. The Selling Shareholders may offer all, some, or none of the Resale Shares. The Selling Shareholders may have sold, transferred, otherwise disposed of or purchased, or may sell, transfer, otherwise dispose of or purchase, at any time and from time to time, shares of our common stock in transactions exempt from the registration requirements of the Securities Act, or in the open market after the date on which they provided the information set forth in the table below. Unless otherwise indicated, and subject to applicable community property laws, we believe that all persons named in the table below have sole voting and investment power with respect to all shares beneficially owned by them.

Information concerning the Selling Shareholders may change over time. Any changed information will be set forth in amendments to the registration statement of which this prospectus forms a part or in supplements to this prospectus, if and when necessary or as otherwise required by law.

PLAN OF DISTRIBUTION FOR THE COMPANY

We may sell our securities directly to one or more investors. We may also sell our securities through agents designated from time to time or to or through underwriters or dealers. The applicable prospectus supplement and any related free writing prospectus will describe the terms of the offering of the securities, including, to the extent applicable:

We may distribute our securities from time to time in one or more transactions at:

Agents

We may designate agents who agree to use their reasonable efforts to solicit purchases of our securities for the period of their appointment or to sell our securities on a continuing basis. We will name any agent involved in the offering and sale of securities and we will describe any fees or commissions we will pay the agent in the applicable prospectus supplement.

Underwriters

If we use underwriters for a sale of securities, the underwriters will acquire the securities for their own account. The underwriters may resell the securities in one or more transactions, including negotiated 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. Subject to certain conditions, the underwriters will be obligated to purchase all the securities of the series offered if they purchase any of the securities of that series. We may change from time to time any public offering price and any discounts or concessions the underwriters allow or reallow or pay to dealers. We may use underwriters with whom we have a material relationship. We will name any underwriter involved in the offering and sale of securities, describe any discount or other compensation and describe the nature of any material relationship in any applicable prospectus supplement. Only underwriters we name in the prospectus supplement will be underwriters of the securities offered by that prospectus supplement.

We may have agreements with the agents and underwriters to indemnify them against specified civil liabilities related to offerings under this prospectus, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities.

Underwriters, dealers and agents that participate in the distribution of the securities may be underwriters as defined in 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 will identify in the applicable prospectus supplement any underwriters, dealers or agents and will describe their compensation. We may have agreements with the underwriters, dealers and agents to indemnify them against specified civil liabilities related to offerings under this prospectus, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Underwriters, dealers and agents may engage in transactions with or perform services for us in the ordinary course of their businesses.

Trading Markets and Listing of Securities

Unless otherwise specified in the applicable prospectus supplement, each class or series of securities will be a new issue with no established trading market, other than our common stock, which is currently listed on the NYSE American. We may elect to list or qualify for trading any other class or series of securities on any securities exchange or other market, but we are not obligated to do so. It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the securities.

Stabilization Activities

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act of 1934, as amended, or the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. 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. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of these activities at any time.

Passive Market Making

Any underwriter who is a qualified market maker on the NYSE American may engage in passive market making transactions in securities listed on the NYSE American 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. A passive market maker must comply with applicable volume and price limitations and must be identified as a passive market maker. 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.

PLAN OF DISTRIBUTION FOR THE SELLING SHAREHOLDERS

Each Selling Shareholder and any of their pledgees, donees, transferees, assignees and successors-in-interest may, from time to time, sell any or all of their Resale Shares on the NYSE American or any other securities exchange, market or trading facility on which shares of our common stock are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Shareholder may use any one or more of the following methods when selling Resale Shares:

The Selling Shareholders may also sell the Resale Shares under Rule 144 under the Securities Act, if available, rather than pursuant to the registration statement of which this prospectus forms a part.

Broker-dealers engaged by the Selling Shareholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Shareholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission, and in the case of a principal transaction a markup or markdown, in each case in compliance with Rule 2121 of the Financial Industry Regulatory Authority.

In connection with any permitted short sale, loan, pledge, option, derivative or hedging transaction, the Selling Shareholders may enter into agreements with broker-dealers or other financial institution that in turn engage in short sales of our common stock in the course of hedging the positions they assume. If any Resale Shares are delivered to a broker-dealer or other financial institution in connection with any such transaction, the broker-dealer or other financial institution may resell the Resale Shares pursuant to this prospectus (as supplemented or amended to reflect such transaction, including, if necessary, updates to the list of selling shareholders to include such broker-dealer or financial institution).

The Selling Shareholders may also transfer and donate the Resale Shares in other circumstances in which case the transferees, donees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus.

The Selling Shareholders and any brokers, dealers or agents that are involved in selling the Resale Shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such brokers, dealers or agents and any profit on the resale of any Resale Shares purchased by them may be deemed to be underwriting compensation under the Securities Act. Each Selling Shareholder has advised us that it does not have any written or oral agreement, understanding or arrangement, directly or indirectly, with any broker, dealer, agent or other person regarding the sale of the Resale Shares. There are no underwriters or coordinating brokers acting in connection with the proposed sale of the Resale Shares by the Selling Shareholders.

Because the Selling Shareholders may be deemed to be “underwriters” within the meaning of the Securities Act, they may be subject to the requirements of the Securities Act to deliver this prospectus to each purchaser at or prior to the time of the sale. We have informed the Selling Shareholders of this requirement, and we will make copies of this prospectus available to them.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the Resale Shares may not simultaneously engage in market making activities with respect to our common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Shareholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of shares of our common stock by the Selling Shareholders or any other person.

We will pay certain fees and expenses incurred by us incident to the registration of the Resale Shares, including SEC filing fees, fees and expenses of compliance with securities laws, and various related expenses. The Selling Shareholders are responsible for all discounts, selling commissions and other costs related to their offer and sale of the Resale Shares.

Unless otherwise indicated in the applicable prospectus supplement, the validity of the securities offered hereby will be passed upon for us by DLA Piper LLP (US), Seattle, Washington.
