PROSPECTUS SUPPLEMENT

(To Prospectus dated August 1, 2024)

Up to $7,500,000

Common Stock

We have entered into a sales agreement with Needham & Company, LLC, acting in its capacity as the sales agent, or Needham, relating to the offer and sale of shares of our common stock, no par value, from time to time, having an aggregate offering price of up to $7,500,000.

Sales of our common stock, if any, under this prospectus supplement may be made in sales deemed to be “at-the-market” equity offerings as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, or the Securities Act, including, without limitation, sales made directly on The Nasdaq Stock Market LLC, or Nasdaq, on any other existing trading market for our common stock or to or through a market maker or through an electronic communications network. Needham is not required to sell any specific amount of securities, but will act as our sales agent on a best efforts basis and will use commercially reasonable efforts to sell on our behalf all of our common stock requested to be sold by us, consistent with its normal trading and sales practices, on mutually agreed terms between Needham and us. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

Needham will be entitled to compensation at a fixed commission rate of 3.0% of the gross proceeds from the sale of our common stock on our behalf pursuant to the sales agreement. In connection with the sale of our common stock on our behalf, Needham will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of Needham will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to Needham against certain civil liabilities, including liabilities under the Securities Act or the Securities Exchange Act of 1934, as amended, or the Exchange Act. We may also sell some or all of the shares of common stock to the sales agent as principal for its own account at a price agreed upon at the time of sale.

As a result of the limitations on the maximum amount of shares that we are eligible to offer and sell under General Instruction I.B.6 of Form S-3, we may currently only offer and sell shares of our common stock having an aggregate offering price of up to $7,500,000 pursuant to the ATM Agreement. However, in the event that our public float increases or decreases, we may sell securities in public primary offerings on Form S-3 with a value up to one-third of our public float, in each case calculated pursuant to General Instruction I.B.6 and subject to the terms of the ATM Agreement. In the event that our public float increases above $75.0 million, we will no longer be subject to the limits in General Instruction I.B.6 of Form S-3.

Our common stock is listed on Nasdaq under the symbol “OCX.” The last reported sale price of our common stock on August 7, 2024 was $3.00 per share.

Investing in our common stock involves a high degree of risk. You should read this prospectus supplement and the accompanying prospectus carefully before you make your investment decision. See “Risk Factors” beginning on page S-5 of this prospectus supplement, as well as the documents incorporated by reference in this prospectus supplement and the accompanying prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement is part of a registration statement that we have filed with the Securities and Exchange Commission, or SEC, utilizing a “shelf” registration process. Under the shelf registration process, we may offer shares of our common stock having an aggregate offering price of up to $100,000,000 under the accompanying prospectus. Under this prospectus supplement and the accompanying prospectus, we may offer shares of our common stock having an aggregate offering price of up to $7,500,000 from time to time at prices and on terms to be determined by market conditions at the time of offering.

We are providing information to you about this offering of shares of our common stock in two separate documents that are bound together: (1) this prospectus supplement, which describes the specific details regarding this offering; and (2) the accompanying prospectus, which provides general information, some of which may not apply to this offering. Generally, when we refer to this “prospectus,” we are referring to both documents combined.

If information in this prospectus supplement is inconsistent with the accompanying prospectus or with any document incorporated by reference that was filed with the SEC before the date of this prospectus supplement, you should rely on this prospectus supplement. Any statement so modified will be deemed to constitute a part of this prospectus only as so modified, and any statement so superseded will be deemed not to constitute a part of this prospectus. However, if any statement in one of these documents is inconsistent with a statement in another document having a later date—for example, a document incorporated by reference in this prospectus supplement, the statement in the document having the later date modifies or supersedes the earlier statement as our business, financial condition, results of operations and prospects may have changed since the earlier dates.

This prospectus supplement, the accompanying prospectus and the documents incorporated into each by reference herein and therein include important information about us, the securities being offered and other information you should know before investing in our securities. You should also read and consider information in the documents we have referred you to in the section of this prospectus supplement and the accompanying prospectus entitled “Where You Can Find More Information” and “Information Incorporated by Reference.”

You should rely only on the information contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus and any free writing prospectus we may provide to you in connection with this offering and the information incorporated or deemed to be incorporated by reference therein. We have not, and Needham has not, authorized anyone to provide you with information that is in addition to or different from that contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. If anyone provides you with different or inconsistent information, you should not rely on it. We are not, and Needham is not, offering to sell these securities in any jurisdiction where the offer or sale is not permitted. You should not assume that the information contained or incorporated by reference in this prospectus supplement or the accompanying prospectus is accurate as of any date other than as of the date of this prospectus supplement or the accompanying prospectus, as the case may be, or in the case of the documents incorporated by reference, the date of such documents regardless of the time of delivery of this prospectus supplement and the accompanying prospectus or any sale of our securities. Our business, financial condition, liquidity, results of operations and prospects may have changed since those dates.

We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference in this prospectus supplement or the accompanying prospectus were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants were accurate only as of the date when made. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

We are offering to sell, and are seeking offers to buy, the common stock only in jurisdictions where such offers and sales are permitted. No action has been or will be taken in any jurisdiction by us or Needham that would permit a public offering of the common stock or the possession or distribution of this prospectus supplement and the accompanying prospectus in any jurisdiction, other than in the United States. Persons outside the United States who come into possession of this prospectus supplement and the accompanying prospectus must inform themselves about, and observe any restrictions relating to, the offering of the common stock and the distribution of this prospectus supplement and the accompanying prospectus outside the United States. This prospectus supplement and the accompanying prospectus do not constitute, and may not be used in connection with, an offer to sell, or a solicitation of an offer to buy, any securities offered by this prospectus supplement and the accompanying prospectus by any person in any jurisdiction in which it is unlawful for such person to make such an offer or solicitation.

MARKET, INDUSTRY AND OTHER DATA

This prospectus supplement contains and incorporates by reference estimates, projections and other information concerning our industry, our business and the markets for our diagnostic tests, including data regarding the estimated size of those markets and their projected growth rates We obtained the industry, market and other data from our own internal estimates and research, as well as from independent industry publications and other publicly available information, including information from government agencies. Although we believe that these sources are reliable, we do not guarantee the accuracy or completeness of third-party information and we have not independently verified that information. Although we are not aware of any misstatements regarding the market and industry data presented in this prospectus and the documents incorporated herein by reference, estimates, forecasts, projections, market research or similar data is inherently subject to uncertainties and actual events or circumstances may differ materially from events and circumstances that are assumed in that data and are subject to change based on various factors, including those discussed under the heading “Risk Factors” in this prospectus supplement and the accompanying prospectus and under similar headings in the other documents that are incorporated by reference into this prospectus. Accordingly, investors should not place undue reliance on this information.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying prospectus contain “forward-looking statements” that involve risks and uncertainties. Our actual results could differ materially from those discussed in the forward-looking statements. The statements contained in this prospectus supplement that are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. Forward-looking statements are often identified by the use of words such as, but not limited to, “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “project,” “seek,” “should,” “strategy,” “target,” “will,” “would” and similar expressions or variations intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These statements are based on the beliefs and assumptions of our management based on information currently available to management but such forward-looking statements are subject to risks, uncertainties and other important factors that could cause actual results and the timing of certain events to differ materially from future results expressed or implied by such forward-looking statements. These important factors include but are not limited to those discussed under the “Risk Factors” sections of this prospectus supplement, the accompanying prospectus, and our most recent Annual Report on Form 10-K, as updated by our subsequent filings under the Exchange Act, and the other periodic reports and other filings that we file from time to time with the SEC, each of which is incorporated by reference in this prospectus supplement in their entirety. Accordingly, we cannot guarantee that we actually will achieve the plans, intentions or expectations expressed in our forward-looking statements and you should not place undue reliance on our forward-looking statements. Furthermore, such forward-looking statements speak only as of the date of this prospectus supplement. Except as required by law, we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.

Please consider our forward-looking statements in light of those risks as you read this prospectus supplement and the accompanying prospectus. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Given these uncertainties, you should not place undue reliance on these forward-looking statements.

You should not assume that the information contained in this prospectus supplement and the accompanying prospectus is accurate as of any date other than as of the date of this prospectus supplement or the accompanying prospectus, as the case may be, or that any information incorporated by reference into this prospectus is accurate as of any date other than the date of the document so incorporated by reference. Except as required by law, we assume no obligation to update these forward-looking statements publicly, or to update the reasons actual results could differ materially from those anticipated in these forward-looking statements, even if new information becomes available in the future. Thus, you should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements.

If one or more of these or other risks or uncertainties materializes, or if our underlying assumptions prove to be incorrect, actual results may vary materially from what we anticipate. All subsequent written and oral forward-looking statements attributable to us or individuals acting on our behalf are expressly qualified in their entirety by this note. Before purchasing any shares of common stock, you should consider carefully all of the factors set forth or referred to in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference that could cause actual results to differ.

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 Part I, Item 1A. Risk Factors of our most recent Annual Report on Form 10-K and in our subsequent Quarterly Reports on Form 10-Q filed with the SEC. You should also refer to the other information contained in this prospectus supplement and 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.”

If one or more of the adverse events relevant to those 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.

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

We have broad discretion in the use of our available cash and other sources of funding, including the net proceeds we may receive from this offering, if any, and may not use them effectively.

Our management has broad discretion in the use of our available cash and other sources of funding, including the net proceeds we receive in this offering, and could spend those resources for purposes other than those described in the “Use of Proceeds” portion of this prospectus supplement, and in ways that do not improve our results of operations or enhance the value of our common stock. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, cause the price of our common stock to decline and delay the development of our product candidates. Pending use in our operations, we may invest our available cash, including the net proceeds we receive in this offering, in a manner that does not produce income or that loses value.

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

The price per share of our common stock being offered may be higher than the net tangible book value per share of our outstanding common stock prior to this offering. Assuming that an aggregate of 2,500,000 shares of our common stock are sold at a price of $3.00 per share, the last reported sale price of our common stock on the Nasdaq on August 7, 2024, for aggregate gross proceeds of $7,500,000 before deducting commissions and estimated offering expenses payable by us, new investors in this offering will incur immediate dilution of $4.67 per share. For a more detailed discussion of the foregoing, see the section entitled “Dilution” on page S-7 of this prospectus supplement. To the extent outstanding stock options or warrants are exercised, there will be further dilution to new investors.

Resales of our common stock in the public market during this offering by our stockholders may cause the market price of our common stock to fall.

We may issue common stock from time to time in connection with this offering. This issuance from time to time of these new shares of our common stock, or our ability to issue these shares of common stock in this offering, could result in resales of our common stock by our current stockholders concerned about the potential dilution of their holdings. In turn, these resales could have the effect of depressing the market price for our common stock.

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

Subject to certain limitations in the sales agreement and compliance with applicable law, we have the discretion to deliver placement notices to Needham at any time throughout the term of the sales agreement. The number of shares that are sold by Needham 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 Needham.

The shares of common stock offered under this prospectus supplement and the accompanying prospectus may be sold in “at-the-market” offerings, and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares under this prospectus supplement and the accompanying prospectus at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience declines in the value of their shares as a result of share sales made at prices lower than the prices they paid.

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

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

USE OF PROCEEDS

We may issue and sell shares of our common stock having aggregate gross proceeds of up to $7,500,000 from time to time under this prospectus supplement and the accompanying prospectus. Because there is no minimum offering amount required as a condition to close this offering, the actual total offering amount, commissions and proceeds to us, if any, are not determinable at this time. The amount of proceeds from this offering will depend upon the number of shares of our common stock sold and the market price at which they are sold. There can be no assurance that we will be able to sell any shares under or fully utilize the sales agreement as a source of financing.

We currently intend to use the net proceeds, if any, from this offering for general corporate and working capital purposes. We may use net proceeds, if any, from this offering, to invest in or acquire other businesses or technologies that we believe are complementary to our own, although we have no binding agreements with respect to any acquisitions as of the date of this prospectus supplement.

In addition, 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 products for development. However, we have no binding agreements with respect to any such potential future acquisitions in place as of the date of this prospectus supplement.

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. Accordingly, 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.

Pending application of the net proceeds as described above, we may temporarily invest the 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 as we 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 on 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 ownership interest will be diluted immediately to the extent of the difference between the public offering price per share and the net tangible book value per share of our common stock after this offering.

Our net tangible book value as of June 30, 2024, was approximately $(33.8) million, or $(2.53) per share of our common stock. 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 June 30, 2024. Dilution with respect to net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the net tangible book value per share of our common stock immediately after this offering.

After giving effect to the issuance and sale of our common stock in the aggregate amount of $7,500,000 in this offering, at an assumed offering price of $3.00 per share, the last reported sale price of our common stock on the Nasdaq on August 7, 2024, and after deducting estimated offering commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of June 30, 2024 would have been approximately $(26.6) million, or $(1.67) per share. This represents an immediate increase in as adjusted net tangible book value of $0.86 per share to existing stockholders and immediate dilution of $4.67 per share to new investors purchasing securities in this offering.

The following table illustrates this per share dilution:

The above discussion and table assumes for illustrative purposes that an aggregate of 2,500,000 shares of our common stock are sold at a price of $3.00 per share, the last reported sale price of our common stock on the Nasdaq on August 7, 2024, for aggregate gross proceeds of approximately $7,500,000. The shares sold in this offering, if any, will be sold from time to time at various prices. An increase of $0.50 per share in the price at which the shares are sold from the assumed offering price of $3.00 per share shown in the table above, assuming all of our common stock in the aggregate amount of $7,500,000 is sold at that price, would decrease our adjusted net tangible book value per share after the offering by $0.04 per share and would increase the dilution in net tangible book value per share to new investors in this offering by $0.54 per share, after deducting estimated offering expenses and commissions payable by us. A decrease of $0.50 per share in the price at which the shares are sold from the assumed offering price of $3.00 per share shown in the table above, assuming all of our common stock in the aggregate amount of $7,500,000 is sold at that price, would increase our adjusted net tangible book value per share after the offering by $0.05 per share and would decrease the dilution in net tangible book value per share to new investors in this offering by $0.55 per share, after deducting estimated offering expenses and commissions payable by us. This information is supplied for illustrative purposes only.

The information above is based on 13,368,387 shares of our common stock outstanding as of August 1, 2024, 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 or we otherwise issue additional shares of common stock or other equity or convertible debt securities in the future, you will experience further dilution.

PLAN OF DISTRIBUTION

We have entered into a sales agreement with Needham & Company, LLC, acting in its capacity as the sales agent, or the sales agent, relating to the sale of shares of our common stock offered by this prospectus supplement. Under this prospectus supplement, in accordance with the terms of the sales agreement, we may sell shares of our common stock for an aggregate offering price of up to $7,500,000 from time to time through the sales agent, acting as the sales agent, subject to certain limitations, including the number or dollar amount of shares registered under the registration statement to which the offering relates. The sales, if any, of shares made under the sales agreement will be made by any method that is deemed an “at the market offering” as defined in Rule 415 promulgated under the Securities Act. We may instruct the sales agent not to sell common stock if the sales cannot be effected at or above the price designated by us from time to time. We or the sales agent may suspend the offering of common stock upon notice and subject to other conditions.

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

We will pay the sales agent an aggregate commission equal to 3% of the gross proceeds from the sale of common stock offered hereby. In addition, we have agreed to reimburse certain expenses of the sales agent in an amount not to exceed an aggregate of $100,000 in connection with the establishment of this “at the market offering” and an aggregate of $7,500 in connection with each periodic update of such “at the market offering.”

In accordance with Financial Industry Regulatory Authority, Inc. Rule 5110, these fees and reimbursed expenses are deemed sales compensation in connection with this offering. We estimate that the total expenses for the offering, excluding compensation payable to the sales agent under the terms of the sales agreement, will be approximately $150,000.

Settlement for sales of common stock will generally occur on the first trading day following the date on which any sales are made, or on some other date that is agreed upon by us and the sales agent in connection with a particular transaction, in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

In connection with the sale of shares of our common stock on our behalf, the sales agent will be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of the sales agent will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to the sales agent against certain civil liabilities, including liabilities under the Securities Act. We have also agreed to reimburse the sales agent for certain other specified expenses.

The offering of our common stock pursuant to this prospectus supplement will terminate upon the earlier of (i) the sale of all of our common stock provided for in this prospectus supplement or (ii) termination of the sales agreement as provided therein.

Our common stock is listed on the Nasdaq under the symbol “OCX.” The transfer agent for our common stock is American Stock Transfer & Trust Company, LLC.

The sales agent and its respective affiliates may in the future provide various investment banking and other financial services for us and our affiliates, for which services they may in the future receive customary fees. To the extent required by Regulation M, the sales agent will not engage in any market making activities involving our common stock while the offering is ongoing under this prospectus supplement.

The validity of the shares of common stock offered hereby will be passed upon for us by Stradling Yocca Carlson & Rauth LLP, Newport Beach, California. Needham is being represented in connection with this offering by DLA Piper LLP (US), Raleigh, North Carolina.

TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

This prospectus is part of the registration statement on Form S-3 that we filed with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (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 million of any of the securities described in this prospectus.

This prospectus provides a general description of the securities we may offer. Each time we offer and sell securities under this prospectus, we will, to the extent required by law, 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. We have not 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.”

The representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document incorporated by reference into this prospectus were made solely for the benefit of the parties to such agreement, including for the purpose of allocating risks among such parties, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants do not purport to be accurate as of any date other than when made. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

Unless otherwise indicated, information contained or incorporated by reference in this prospectus concerning our industry, including our general expectations and market opportunity, is based on information from our own management estimates and research, as well as from industry and general publications and research, surveys and studies conducted by third parties. Management estimates are derived from publicly available information, our knowledge of our industry and assumptions based on such information and knowledge, which we believe to be reasonable. In addition, assumptions and estimates of our and our industry’s future performance are necessarily uncertain due to a variety of factors, including those described in the section of this prospectus entitled “Risk Factors.” These and other factors could cause our future performance to differ materially from our assumptions and estimates.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the information incorporated by reference in this prospectus contain “forward-looking statements,” which include information relating to future events, future financial performance, strategies, expectations, competitive environment and regulation. Words such as “may,” “should,” “could,” “would,” “predicts,” “potential,” “continue,” “expects,” “anticipates,” “future,” “intends,” “plans,” “believes,” “estimates,” and similar expressions, as well as statements in future tense, are intended to identify forward-looking statements. Forward-looking statements should not be read as a guarantee of future performance or results and may not be accurate indications of when such performance or results will actually be achieved. Forward-looking statements are based on information we have when those statements are made or our management’s good faith belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:

You should read this prospectus and any related free-writing prospectus and the documents incorporated by reference in this prospectus with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect. The forward-looking statements contained or incorporated by reference in this prospectus are expressly qualified in their entirety by this cautionary statement. We do not undertake any obligation to publicly update any forward-looking statement to reflect events or circumstances after the date on which any such statement is made or to reflect the occurrence of unanticipated events.

PROSPECTUS SUMMARY

This summary provides an overview of selected information contained elsewhere or incorporated by reference in this prospectus and does not contain all of the information you should consider before investing in our securities. You should carefully read the prospectus, the information incorporated by reference and the registration statement of which this prospectus is a part in their entirety before investing in our securities, including the information discussed under “Risk Factors” in this prospectus and the documents incorporated by reference and our financial statements and related notes that are incorporated by reference in this prospectus. In this prospectus, unless the context indicates otherwise, “Oncocyte,” the “Company,” the “registrant,” “we,” “us,” “our,” or “ours” refer to Oncocyte Corporation and its subsidiaries.

Overview

We are a partner in the healthcare and life science field to researchers and physicians through our development and acquisitions of proprietary molecular technologies in the fields of oncology and transplantation. Through a series of acquisitions, we have built a portfolio of differentiated content with utility in well-established clinical and research markets.

With the increased adoption of precision medicine, healthcare providers are relying on advanced testing to identify patients who will benefit from new, targeted treatments and therapies that are more effective and often have fewer side effects than chemotherapy and other traditional treatments. In addition to identifying these individualized treatment options, researchers and healthcare providers are looking to new technologies to rapidly identify when medical or therapeutic interventions are necessary. We are leveraging our experience in oncology and transplantation to develop and commercialize diagnostic testing at our licensed and accredited laboratory as well as focusing on the development of distributable kitted formats of these technologies so that researchers may study how these tests can be further utilized in other types of cancers. Commercialization of these products, which are intended to be sold for research purposes in the United States and labeled “For Research Use Only”, is expected to occur through a mix of direct sales, partnering and distribution agreements, and licensing.

We have a laboratory and pharma services lab, certified under the Clinical Laboratory Improvements Amendment and accredited by the Collage of American Pathologists, in Nashville, Tennessee, and a research and development lab in Göttingen, Germany. We may sometimes refer to our technologies as “diagnostic tests.” Our laboratory developed tests are intended to help support and inform physician decision-making but are not themselves diagnostic or prescriptive of treatment decisions. They are critical to our ability to carry out our mission to improve patient outcomes by providing patient specific insights that inform critical provider decisions throughout the patient care journey. We believe that if clinicians are given the right information and educational tools, they will make the right choices with their patients.

We believe that the experience of our team with diverse technologies through our pharma services activities (acquired through Insight Genetics), strong scientific integrity regarding evidence generation and innovation mentality, alongside our flexibility in operations and regulatory strategy, will drive our success, differentiate us from our competition, and are foundational to our future.

We plan to expand our role in the rapidly evolving healthcare market by strengthening our positions across our portfolio of capabilities, growing strategic opportunities that drive new business, and differentiating our unique offerings, capabilities, and financial performance. To do so, we are focusing on executing the technology priorities discussed below, which have evolved to reflect our operations and strategic vision.

Implications of Being a Smaller Reporting Company

We are a “smaller reporting company” and accordingly may provide less public disclosure than larger public companies. As a result, the information that we provide to our stockholders may be different than you might receive from other public reporting companies in which you hold equity interests.

Corporate information

We were incorporated in September 2009 in the state of California. 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 accessed through our website is not incorporated into this prospectus and is not a part of this prospectus.

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 Part I, Item 1A. Risk Factors of our most recent Annual Report on Form 10-K and in our subsequent Quarterly Reports on Form 10-Q filed with the SEC. You should also refer to the other information contained in this prospectus and the applicable prospectus supplement and the documents incorporated by reference into this prospectus and the applicable prospectus supplement, 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.”

If one or more of the adverse events relevant to those 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.

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.

DIVIDEND POLICY

We have never paid cash dividends on our capital stock and we do not anticipate paying cash dividends in the foreseeable future as we 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 on our financial condition, results of operations, capital requirements 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 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.

The summaries below provide a general description of the securities we 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 capital 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 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 230,000,000 shares of common stock, no par value per share, and up to 5,000,000 shares of preferred stock, no par value per share. As of July 30, 2024, there were 13,364,637 shares of common stock outstanding and no shares of preferred stock outstanding.

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. We have never paid cash dividends on our capital stock and we do not anticipate paying cash dividends in the foreseeable future as we intend to retain our capital resources for reinvestment in our business.

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. The shares of common stock offered under this prospectus or upon the conversion of any preferred stock or exercise of any warrants offered pursuant to this prospectus, when paid for and issued in accordance with the applicable definitive documents under which they are to be issued, will also be fully paid and non-assessable.

Our common stock is listed on Nasdaq 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.

On April 5, 2023, we redeemed 1,064 shares of the Series A Redeemable Convertible Preferred Stock, which represented a portion of our outstanding shares of preferred stock at the time, for approximately $1.1 million. On April 11, 2024, we redeemed all remaining shares of our Series A Redeemable Convertible Preferred Stock for approximately $5.4 million. 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, but subsequent to the issue of shares of that series the number of shares of the series may not be decreased below the number of such shares 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.

PLAN OF DISTRIBUTION

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 Nasdaq. 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 Nasdaq may engage in passive market making transactions in securities listed on the Nasdaq 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.

LEGAL MATTERS

The validity of the securities offered by this prospectus will be passed upon for us by Stradling Yocca Carlson & Rauth LLP, Newport Beach, California.
