Up to    Shares of Common Stock

Up to    Pre-Funded Warrants to Purchase up to    Shares of Common Stock

Up to    Series E Warrants to Purchase up to    Shares of Common Stock

Up to    Series F Warrants to Purchase up to    Shares of Common Stock

Up to    Shares of Common Stock Issuable Upon Exercise of the

Pre-Funded Warrants, Series E Warrants and Series F Warrants

We are offering up to    shares of common stock, par value $0.0001 per share (“common stock”), together with Series E warrants to purchase up to    shares of common stock (the “Series E Warrants”) and Series F warrants to purchase up to    shares of common stock (the “Series F Warrants”, and together with the Series E Warrants, the “Warrants”) at an assumed combined public offering price of $   per share and accompanying Warrants, which is equal to the closing price per share of our common stock on the Nasdaq Capital Market on   , 2025 pursuant to this prospectus. The shares of common stock and Warrants will be separately issued, but must be purchased together in this offering. Each share of common stock is being sold together with one Series E Warrant to purchase one share of common stock and one Series F Warrant to purchase one share of common stock. Each Warrant will have an assumed exercise price of $   per share (representing 100% of the combined price at which a share of common stock and accompanying Warrants are sold to the public in this offering) and will be exercisable beginning on the effective date of stockholder approval of the issuance of the shares upon exercise of the Warrants (“Warrant Stockholder Approval”); provided, however, if the Pricing Conditions (as defined below) are met, the Warrant Stockholder Approval will not be required and the Warrants will be exercisable upon issuance (the “Initial Exercise Date”). The Series E Warrants will expire on the   -year anniversary of the Initial Exercise Date. The Series F Warrants will expire on the   -month anniversary of the Initial Exercise Date. As used herein, “Pricing Conditions” means that the combined public offering price per share and accompanying Warrants is such that Warrant Stockholder Approval is not required under the rules of The Nasdaq Stock Market LLC (“Nasdaq”) because either (i) the offering is an at-the-market offering under Nasdaq rules and such price equals or exceeds the sum of (a) the applicable “Minimum Price” per share under Nasdaq Rule 5635(d) plus (b) $0.125 per whole share of common stock underlying the Warrants or (ii) the offering is a discounted offering where the pricing and discount (including attributing a value of $0.125 per whole share underlying the Warrants) meet the pricing requirements under Nasdaq’s rules.

We are also offering up to    pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to an aggregate of    shares of common stock to those purchasers whose purchase of shares of common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock following the consummation of this offering in lieu of the shares of our common stock that would result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%). Each Pre-Funded Warrant will be exercisable for one share of common stock at an exercise price of $0.0001 per share. Each Pre-Funded Warrant is being issued together with the same Warrants described above being issued with each share of common stock. The assumed combined public offering price for each such Pre-Funded Warrant, together with the accompanying Warrants, is $   , which is equal to the closing price of our common stock on the Nasdaq Capital Market on   , 2025, less the $0.0001 per share exercise price of each such Pre-Funded Warrant. Each Pre-Funded Warrant will be exercisable upon issuance and will expire when exercised in full. The Pre-Funded Warrants and accompanying Warrants are immediately separable and will be issued separately in this offering, but must be purchased together in this offering. For each Pre-Funded Warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. This offering also relates to the shares of common stock issuable upon the exercise of the Warrants and the Pre-Funded Warrants.

This offering will terminate on   , unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The combined public offering price per share (or Pre-Funded Warrant) and accompanying Warrants will be fixed for the duration of this offering.

We have engaged   (the “placement agent”) to act as our exclusive placement agent in connection with this offering. The placement agent has agreed to use its reasonable best efforts to arrange for the sale of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities we are offering, and the placement agent is not required to arrange the purchase or sale of any specific number or dollar amount of securities. We have agreed to pay to the placement agent the placement agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus. There is no arrangement for funds to be received in escrow, trust or similar arrangement. There is no minimum offering requirement. We will bear all costs associated with the offering. See “Plan of Distribution” on page 20 of this prospectus for more information regarding these arrangements.

Our common stock is currently listed on the Nasdaq Capital Market under the symbol “BNGO.” On   , 2025, the closing price of our common stock on the Nasdaq Capital Market was $   per share. All share, Warrant and Pre-Funded Warrant numbers are based on an assumed combined public offering price of $   per share and accompanying Warrants and $   per Pre-Funded Warrant and accompanying Warrants. There is no established public trading market for the Pre-Funded Warrants or Warrants that are part of this offering, and we do not expect a market to develop. We do not intend to apply for listing of the Pre-Funded Warrants or Warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the Pre-Funded Warrants and Warrants will be limited.

Certain information in this prospectus is based on an assumed combined public offering price of $   per share and accompanying Warrants, the last reported sale price of our common stock on the Nasdaq Capital Market on   , 2025 (or assumed combined public offering price of $   per Pre-Funded Warrant and accompanying Warrants). The actual combined public offering price per share and accompanying Warrants and the actual combined public offering price per Pre-Funded Warrant and accompanying Warrants, as the case may be, will be determined between us, the placement agent and investors in this offering based on market conditions at the time of pricing and may be at a discount to the current market price of our common stock. Therefore, the recent market price used throughout this prospectus may not be indicative of the final offering price.

An investment in our securities involves a high degree of risk. Before purchasing any of our securities you should carefully consider the risk factors set forth below and those incorporated by reference in this prospectus from our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, and any subsequent updates described in our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, as well as the risks, uncertainties and additional information set forth in our SEC reports on Forms 10-K, 10-Q, and 8-K and in the other documents incorporated by reference in this prospectus. For a description of these reports and documents, and information about where you can find them, see “Where You Can Find More Information” and “Information Incorporated by Reference.” Additional risks not presently known or that we presently consider to be immaterial could subsequently materially and adversely affect our financial condition, results of operations, business, and prospects.

Our management will have broad discretion in the application of the net proceeds, including for any of the purposes described in the section of this prospectus titled “Use of Proceeds”. 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 net proceeds are being used appropriately. 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 securities to decline and delay the commercialization of our products and technologies. Pending the application of these funds, we may invest the net proceeds from this offering in a manner that does not produce income or that loses value.

The combined public offering price per share of common stock and accompanying Warrants, and the combined public offering price of each Pre-Funded Warrant and accompanying Warrants, will be substantially higher than the as adjusted net tangible book value per share of our common stock after giving effect to this offering.

Assuming the sale of shares of our common stock and accompanying Warrants to purchase up to shares of common stock at an assumed combined public offering price of $    per share and accompanying Warrants, the closing sale price per share of our common stock on the Nasdaq Capital Market on    , 2025, assuming no sale of any Pre-Funded Warrants in this offering, no exercise of the Warrants being offered in this offering and after deducting the placement agent fees and commissions and estimated offering expenses payable by us, you will incur immediate dilution of approximately $    per share. As a result of the dilution in net tangible book value to investors purchasing securities in this offering, investors may receive significantly less than the purchase price paid in this offering, if anything, in the event of the liquidation of our company. See the section titled “Dilution” below for a more detailed discussion of the dilution you will incur if you participate in this offering. To the extent shares are issued under outstanding options and warrants at exercise prices lower than the public offering price of our common stock in this offering, including the shares underlying the Pre-Funded Warrants, holders will incur further dilution.

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

The Warrants and Pre-Funded Warrants offered hereby do not confer any rights of share of common stock ownership on their holders, such as voting rights, but rather merely represent the right to acquire shares of common stock at a fixed price. Specifically, commencing on the date of issuance, holders of the Warrants may acquire the shares of common stock issuable upon exercise of such warrants at an assumed exercise price of $    per share of common stock, and holders of the Pre-Funded Warrants may acquire the shares of common stock issuable upon exercise of such warrants at an exercise price of $0.0001 per share of common stock. Moreover, following this offering, the market value of the Warrants and Pre-Funded Warrants is uncertain and there can be no assurance that the market

value of the Warrants or Pre-Funded Warrants will equal or exceed their respective public offering prices. There can be no assurance that the market price of the shares of common stock will ever equal or exceed the exercise price of the Warrants or Pre-Funded Warrants, and consequently, whether it will ever be profitable for holders of Warrants to exercise the Warrants or for holders of the Pre-Funded Warrants to exercise the Pre-Funded Warrants.

Until holders of the Warrants and the Pre-Funded Warrants acquire shares of our common stock upon exercise thereof, such holders will have no rights with respect to the shares of our common stock underlying such warrants, except to the extent that holders of such Warrants and Pre-Funded Warrants will have certain rights to participate in distributions or dividends paid on our common stock as set forth in the Warrants and the Pre-Funded Warrants. Upon exercise of the Warrants and the Pre-Funded Warrants, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

The Warrants will have an assumed exercise price of $    per share and will be exercisable beginning on the effective date of the Warrant Stockholder Approval; provided, however, that if the Pricing Conditions are met, the Warrants will be exercisable upon issuance (the “Initial Exercise Date”). The Series E Warrants will expire on the    -year anniversary of the Initial Exercise Date. The Series F Warrants will expire on the    -month anniversary of the Initial Exercise Date.

While we intend to promptly seek Warrant Stockholder Approval, there is no guarantee that the Warrant Stockholder Approval will ever be obtained. If we are unable to obtain the Warrant Stockholder Approval, the Warrants may have no value.

In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers who enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The ability to pursue a claim for breach of contract provides those investors with the means to enforce the covenants uniquely available to them under the securities purchase agreement including, but not limited to: (i) timely delivery of securities; (ii) agreement to not enter into variable rate financings for a period of time after closing, subject to certain exceptions; (iii) agreement to not enter into any financings for a period of time after closing, subject to certain exceptions; and (iv) indemnification for breach of contract.

The placement agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities in this offering. The placement agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth herein. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to support our continued operations, including our near-term continued operations. Thus, we may not raise the amount of capital we believe is required for our operations in the short-term and may need to raise additional funds, which may not be available or available on terms acceptable to us.

Our ability to publicly or privately sell equity securities and the liquidity of our common stock could be adversely affected if we are delisted from the Nasdaq Capital Market or if we are unable to transfer our listing to another stock

market. In order to maintain this listing, we must satisfy minimum financial and other continued listing requirements and standards, including a requirement to maintain a minimum bid price of our common stock of $1.00 per share pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”).

On multiple occasions in the past, we have failed to comply with the per share minimum required for continued listing on Nasdaq. For example, on May 30, 2023. we received a letter (the “First Notice”) from Nasdaq advising us that for 30 consecutive trading days preceding the date of the First Notice, the bid price of our common stock had closed below the Minimum Bid Price Requirement.

While we implemented a reverse stock split, effective August 4, 2023, that temporarily enabled us to satisfy the Minimum Bid Price Requirement, on July 11, 2024, we received another letter (the “Second Notice”) from Nasdaq advising us that for 30 consecutive trading days preceding the date of the Second Notice, the bid price of our common stock had closed below the Minimum Bid Price Requirement. The Second Notice had no effect on the listing of our common stock, and our common stock continues to trade on Nasdaq under the symbol “BNGO.”

Even though we have implemented another reverse stock split, effective January 24, 2025, and received a letter from Nasdaq on February 10, 2025 that informed us that we had regained compliance with the Minimum Bid Price Requirement, we cannot assure you that we will be able to continue to satisfy the Minimum Bid Price Requirement or each other Nasdaq requirement for continued listing. If we fail to satisfy any Nasdaq requirement for continued listing, Nasdaq staff could provide notice that our common stock may become subject to delisting. Accordingly, there can be no guarantee that we will be able to maintain our Nasdaq listing. If our common stock is delisted by Nasdaq, it could lead to a number of negative consequences, including an adverse effect on the price of our common stock, increased volatility in our common stock, reduced liquidity in our common stock, the loss of federal preemption of state securities laws and greater difficulty in obtaining financing. In addition, delisting of our common stock could deter broker-dealers from making a market in or otherwise seeking or generating interest in our common stock, could result in a loss of current or future coverage by certain sell-side analysts and might deter certain institutions and persons from investing in our securities at all. Moreover, any such delisting could trigger a default or event of default under certain agreements that we have in place with third parties. Delisting could also cause a loss of confidence of our customers, collaborators, vendors, suppliers and employees, which could harm our business and future prospects.

We have never declared or paid any cash dividends on our capital stock, and you should not rely on an investment in our common stock to provide dividend income. We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

We estimate that the net proceeds from the offering will be approximately $    million, assuming a combined public offering price per share of common stock and accompanying Warrants of $   , the closing price per share of our common stock on the Nasdaq Capital Market on     , 2025, after deducting the placement agent fees and estimated offering expenses payable by us, assuming no sale of any Pre-Funded Warrants and no exercise of any of the Warrants offered hereunder. However, because this is a best efforts offering and there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, the placement agent fees and net proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus. As a result, we may receive significantly less in net proceeds. We estimate that our net proceeds from the sale of 75%, 50%, and 25% of the maximum number of securities offered in this offering would be approximately $   , $   , and $   , respectively, after deducting the estimated placement agent fees and estimated offering expenses payable by us, and assuming no sale of any Pre-Funded Warrants and assuming no exercise of the Warrants.

A $    increase or decrease in the assumed combined public offering price of $    per share of common stock and accompanying Warrants would increase or decrease the net proceeds from this offering by approximately $   , assuming that the number of shares of common stock and accompanying Warrants offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting the estimated placement agent fees and estimated offering expenses payable by us. An increase or decrease of      shares of common stock and accompanying Warrants offered by us would increase or decrease our proceeds by approximately $   , assuming the assumed combined public offering price of $    per share of common stock and accompanying Warrants remains the same, and after deducting placement agent fees and estimated offering expenses payable by us.

These estimates exclude the proceeds, if any, from the exercise of the Warrants issued in this offering. If all of the Warrants issued in this offering were to be exercised in cash at an assumed exercise price of $    per share of common stock, we would receive additional proceeds of approximately $    million. We cannot predict when or if these Warrants will be exercised. It is possible that these Warrants may expire and may never be exercised. Additionally, the Warrants contain a cashless exercise provision that permit exercise of Warrants on a cashless basis at any time where there is no effective registration statement under the Securities Act covering the issuance of the underlying shares.

We intend to use the net proceeds from the offering for working capital and general corporate purposes. These expected uses represent our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve. The amounts and timing of these expenditures will depend on numerous factors, including the development of our current business initiatives. We have no specific acquisition contemplated at this time. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds from this offering. As a result, our management will have broad discretion in the application of the net proceeds from this offering, and the investors will be relying on the judgment of our management regarding the application of the net proceeds from this offering. The amounts and timing of our actual expenditures will depend on numerous factors, including factors described under “Risk Factors” in this prospectus and the documents incorporated by reference herein and therein.

Pending application of the net proceeds as described above, we intend to invest the net proceeds of this offering in short-term, investment-grade, interest-bearing securities.

If you invest in our securities in this offering, your interest will be diluted immediately to the extent of the difference between the public offering price paid by the purchasers of the shares of common stock and accompanying Warrants sold in this offering and the as-adjusted net tangible book value per shares of common stock after this offering.

The net tangible book value of our common stock as of March 31, 2025, was approximately $39.8 million, or approximately $12.84 per share of common stock. Net tangible book value per share represents the amount of our total tangible assets less total liabilities divided by the total number of our shares of common stock outstanding as of March 31, 2025.

After giving effect to the sale by us in this offering of shares of common stock and accompanying Warrants at an assumed combined public offering price of $    per share and accompanying Warrants, and assuming such Warrants are classified and accounted for as equity, our as adjusted net tangible book value as of March 31, 2025 would have been approximately $    million, or approximately $    per share of common stock. This represents an immediate increase in net tangible book value of approximately $    per share of common stock to our existing stockholders and an immediate dilution in as adjusted net tangible book value of approximately $    per share of common stock to purchasers of common stock in this offering, as illustrated by the following table:

In accordance with the rules of the SEC, in the event that the actual combined public offering per share of common stock and accompanying Warrants is more or less than the assumed combined public offering price of $    per share and accompanying Warrants (the closing price of our common stock on the Nasdaq Capital Market on    , 2025), the number of shares and/or Pre-Funded Warrants and Warrants we sell may be decreased or increased so long as the aggregate offering amount does not exceed the total amount registered on the registration statement of which this prospectus forms a part. Assuming a total offering amount of $   , for every $0.10 increase in the assumed combined public offering price per share and accompanying Warrants, we would sell     fewer shares of common stock and/or Pre-Funded Warrants and accompanying Warrants and for every $0.10 decrease in the assumed combined public offering price per share and accompanying Warrants, we would sell     additional shares of common stock and/or Pre-Funded Warrants and accompanying Warrants. Each $0.10 increase in the assumed combined public offering price per share and accompanying Warrants would increase the as adjusted net tangible book value per share by $    per share and increase the dilution per share to investors participating in this offering by $    per share after deducting estimated offering expenses payable by us. Each $0.10 decrease in the assumed combined public offering price per share and accompanying Warrants would decrease the as adjusted net tangible book value per share by $    per share and decrease the dilution per share to investors participating in this offering by $    per share, after deducting estimated offering expenses payable by us.

The table and discussion above are based on 3,101,400 shares of common stock outstanding as of March 31, 2025, and excludes as of such date:

To the extent that any outstanding options or warrants are exercised, new options or other equity awards are issued under our equity incentive plans, or we issue additional shares in the future, there will be further dilution to new investors participating in this offering.

The information discussed above is illustrative only and will adjust based on the actual public offering price, the actual number of shares and Warrants that we offer in this offering, and other terms of this offering determined at pricing. Except as indicated otherwise, the discussion and table above each assume (i) no sale of Pre-Funded Warrants, which, if sold, would reduce the number of shares of common stock that we are offering on a one-for-one basis and (ii) no exercise of Warrants accompanying the shares of common stock sold in this offering.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain any future earnings for use in the operation of our business and do not intend to declare or pay any cash dividends in the foreseeable future. Any future determination to pay dividends on our capital stock would be at the discretion of our board of directors, subject to applicable laws, and would depend on our financial condition, results of operations, capital requirements, general business conditions and other factors that our board of directors considers relevant.

The following summary describes our securities registered under Section 12 of the Exchange Act, certain provisions of our amended and restated certificate of incorporation, as amended (“Restated Certificate”), our amended and restated and bylaws, as amended (“Bylaws”), and certain provisions of the General Corporation Law of the State of Delaware (“DGCL”). Because it is only a summary, the following description of our capital stock is not complete and does not contain all of the information that may be important to you. The following summary is subject to and qualified in its entirety by reference to our Restated Certificate and Bylaws, copies of which are filed as exhibits to our Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, filed with the SEC on May 14, 2025, and the forms of securities, copies of which are filed as exhibits to the registration statement of which this prospectus forms a part, which are incorporated by reference herein.

The Restated Certificate authorizes us to issue 400,000,000 shares of common stock, par value $0.0001 per share, and 10,000,000 shares of preferred stock, par value $0.0001 per share. Our board of directors has the authority, without stockholder approval, except as required by the listing standards of The Nasdaq Stock Market LLC, to issue additional shares of our capital stock. In addition, our board of directors has the authority, without further action by our stockholders, to designate the rights, preferences, privileges, qualifications and restrictions of our preferred stock in one or more series.

As of July 14, 2025, there were 4,115,695 shares of common stock outstanding. Our authorized but unissued shares of common stock and preferred stock are available for issuance without further action by our stockholders, unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded in the future.

Our common stock is entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders, including the election of directors, and does not have cumulative voting rights. The Restated Certificate establishes a classified board of directors that is divided into three classes with staggered three-year terms. Only the directors in one class will be subject to election by a plurality of the votes cast at each annual meeting of our stockholders, with the directors in the other classes continuing for the remainder of their respective three-year terms.

Except as otherwise expressly provided in the Restated Certificate or required by applicable law, all shares of common stock have the same rights and privileges and rank equally, share ratably, and are identical in all respects for all matters, including those described below.

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

Liquidation Rights. In the event of our liquidation, dissolution or winding-up, holders of our common stock are entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities, subject to the satisfaction of any liquidation preference granted to the holders of any outstanding shares of preferred stock.

The holders of our shares of common stock are not entitled to preemptive rights, and are not subject to conversion, redemption or sinking fund provisions. The rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that we may designate and issue in the future.

Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of the common stock. The issuance of preferred stock,

while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in our control that may otherwise benefit holders of our common stock and may adversely affect the market price of the common stock and the voting and other rights of the holders of common stock.

The provisions of the DGCL, the Restated Certificate and the Bylaws, certain provisions of which are summarized below, may have the effect of delaying, deferring or discouraging another person from acquiring control of our company. They are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us because negotiation of these proposals could result in an improvement of their terms.

We are subject to Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

In general, Section 203 defines a “business combination” to include the following:

In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s affiliates and associates, beneficially owns, or is an affiliate or associate of the corporation and within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

A Delaware corporation may “opt out” of these provisions with an express provision in its certificate of incorporation. We have not opted out of these provisions, which may as a result, discourage or prevent mergers or other takeover or change of control attempts of us.

Among other things, the Restated Certificate and the Bylaws:

The foregoing provisions make it difficult for another party to obtain control of us by replacing our board of directors. Since our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede or discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise.

These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal and to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and may have the effect of deterring hostile takeovers or delaying changes in our control or management. As a consequence, these provisions may also inhibit fluctuations in the market price of our stock that could result from actual or rumored takeover attempts.

The Restated Certificate provides that the Court of Chancery of the State of Delaware is the exclusive forum for: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders; (iii) any action asserting a claim against us or any of our directors or officers or other employees arising under the Delaware General Corporation Law, the Restated Certificate or the Bylaws; or (iv) any action asserting a claim against us or any of our directors or officers or other employees that is governed by the internal affairs doctrine. The Restated Certificate further provides that U.S. federal district courts will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. These choice of forum provisions of the Restated Certificate will not apply to suits brought to enforce a duty or liability created by the Exchange Act.

The transfer agent and registrar for our common stock is Equiniti Trust Company, LLC.

Our common stock is currently listed on the Nasdaq Capital Market under the symbol “BNGO.”

We are offering up to     shares of our common stock, Series E Warrants to purchase up to     shares of common stock and Series F Warrants to purchase up to     shares of common stock. We are also offering Pre-Funded Warrants to those purchasers whose purchase of shares of common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding shares of common stock following the consummation of this offering in lieu of the shares of common stock that would result in such excess ownership. Each Pre-Funded Warrant will be exercisable for one share of common stock. Each Pre-Funded Warrant is being issued together with the same Warrants described above being issued with each share of common stock. For each Pre-Funded Warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. The shares of common stock or Pre-Funded Warrants, as the case may be, and the accompanying Warrants, can only be purchased together in this offering, but the shares of common stock and Pre-Funded Warrants and accompanying Warrants are immediately separable and will be issued separately in this offering. We are also registering the shares of common stock issuable from time to time upon exercise of the Pre-Funded Warrants and Warrants offered hereby.

The material terms and provisions of our common stock are described under the section “Description of Capital Stock” in this prospectus.

The following is a summary of certain terms and provisions of the Series E Warrants and Series F Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Warrants, the forms of which will be filed as exhibits to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the forms of Warrant for a complete description of the terms and conditions of the Warrants. The Series E Warrants and Series F Warrants are identical except with regard to their duration.

Each Warrant offered hereby will have an assumed exercise price equal to $   (representing 100% of the price at which a share of common stock and accompanying Warrants are sold to the public in this offering). The Warrants will be exercisable beginning on the effective date of Warrant Stockholder Approval; provided, however, that if the Pricing Conditions are met, the Warrants will be exercisable upon issuance (the “Initial Exercise Date”). The Series E Warrants will expire on the    -year anniversary of the Initial Exercise Date. The Series F Warrants will expire on the    -month anniversary of the Initial Exercise Date. The exercise price and number of shares of common stock issuable upon exercise of the Warrants is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. The Warrants will be issued separately from the common stock or Pre-Funded Warrants, respectively, and may be transferred separately immediately thereafter. The Warrants will be issued in certificated form only.

We intend to promptly, and in no event later than     days after the consummation of this offering, seek stockholder approval for the issuance of shares of common stock issuable upon exercise of the Warrants but we cannot assure you that such stockholder approval will be obtained; provided, however, that, if and only if the Pricing Conditions are satisfied, then we will not seek Warrant Stockholder Approval. We have agreed with the investors in this offering that, if we do not obtain stockholder approval for the issuance of the shares of common stock upon exercise of the Warrants at the first stockholder meeting for such purpose after this offering, we will call a stockholder meeting every     days thereafter until the earlier of the date we obtain such approval or the Warrants are no longer outstanding, provided, however, that, if and only if the Pricing Conditions are satisfied, then we will not seek Warrant Stockholder Approval.

The Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of such holder’s Warrants to the extent that the holder would own more than 4.99% of the

outstanding common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the holder’s Warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Warrants.

If, at the time a holder exercises its Warrants, a registration statement registering the issuance or resale of the shares of common stock underlying the Warrants under the Securities Act is not then effective or available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the Warrant.

In the event of any fundamental transaction, as described in the Warrants and generally including any merger or consolidation with or into another entity, sale of all or substantially all of our assets, tender offer or exchange offer, or reclassification of our common stock, then upon any subsequent exercise of a Warrant, the holder will have the right to receive as alternative consideration, for each share of our common stock that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of shares of common stock of the successor or acquiring corporation or of our Company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of our common stock for which the Warrant is exercisable immediately prior to such event. Notwithstanding the foregoing, in the event of a fundamental transaction, the holders of the Warrants have the right to require us or a successor entity to redeem the Warrants for cash in the amount of the Black-Scholes Value (as defined in each Warrant) of the remaining unexercised portion of the Warrants on the date of the consummation of such fundamental transaction, concurrently with or within 30 days following the consummation of a fundamental transaction.

However, in the event of a fundamental transaction which is not in our control, including a fundamental transaction not approved by our board of directors, the holders of the Warrants will only be entitled to receive from us or our successor entity, as of the date of consummation of such fundamental transaction the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of the Warrant that is being offered and paid to the holders of our common stock in connection with the fundamental transaction, whether that consideration is in the form of cash, stock or any combination of cash and stock, or whether the holders of our common stock are given the choice to receive alternative forms of consideration in connection with the fundamental transaction.

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

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

There is no established trading market for the Warrants, and we do not expect an active trading market to develop. We do not intend to apply to list the Warrants on the Nasdaq Capital market or any other securities exchange or other trading market. Without a trading market, the liquidity of the Warrants will be extremely limited. The shares of common stock issuable upon exercise of the Warrants are currently traded on the Nasdaq Capital Market.

Except as otherwise provided in the Warrants or by virtue of the holder’s ownership of shares of our common stock, such holder of Warrants does not have the rights or privileges of a holder of our common stock, including any voting rights, until such holder exercises such holder’s Warrants.

No term of the Warrants may be amended or waived without the written consent of the majority of the holders of the Warrants purchased in this offering.

The following summary of certain terms and provisions of the Pre-Funded Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Pre-Funded Warrant, the form of which will be filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of Pre-Funded Warrant for a complete description of the terms and conditions of the Pre-Funded Warrants.

Each Pre-Funded Warrant offered hereby will have an initial exercise price per share of common stock equal to $0.0001. The Pre-Funded Warrants will be immediately exercisable and will expire when exercised in full. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of share dividends, share splits, reorganizations or similar events affecting our shares of common stock and the exercise price.

The Pre-Funded Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the Pre-Funded Warrant to the extent that the holder would own more than 4.99% of the outstanding shares of common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of beneficial ownership of outstanding shares after exercising the holder’s Pre-Funded Warrants up to 9.99% of the number of our shares of common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Pre-Funded Warrants. Purchasers of Pre-Funded Warrants in this offering may also elect prior to the issuance of the pre- funded warrants to have the initial exercise limitation set at 9.99% of our outstanding shares of common stock.

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

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

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

There is no trading market available for the Pre-Funded Warrants on any securities exchange or nationally recognized trading system, and we do not expect a trading market to develop. We do not intend to list the Pre-Funded Warrants on the Nasdaq Capital Market or any other securities exchange or nationally recognized trading market. Without a trading market, the liquidity of the Pre-Funded Warrants will be extremely limited. The shares of common stock issuable upon exercise of the Pre-Funded Warrants are currently traded on the Nasdaq Capital Market.

Except as otherwise provided in the Pre-Funded Warrants or by virtue of such holder’s ownership of shares of common stock, the holders of the Pre-Funded Warrants do not have the rights or privileges of holders of our shares of common stock, including any voting rights, until they exercise their Pre-Funded Warrants. The Pre-Funded Warrants will provide that holders have the right to participate in distributions or dividends paid on our shares of common stock.

In the event of a fundamental transaction, as described in the Pre-Funded Warrants and generally including any reorganization, recapitalization or reclassification of our shares of common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding securities, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding shares of securities, the holders of the Pre-Funded Warrants will be entitled to receive upon exercise of the pre- funded warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Pre-Funded Warrants immediately prior to such fundamental transaction on a net exercise basis.

Pursuant to an engagement agreement, dated    (the “Engagement Agreement”), we have engaged    (the “placement agent”) to act as our exclusive placement agent to solicit offers to purchase the securities offered by this prospectus on a reasonable best efforts basis. The Engagement Agreement does not give rise to any commitment by the placement agent to purchase any of our securities, and the placement agent will have no authority to bind us by virtue of the Engagement Agreement. The placement agent is not purchasing or selling any securities, nor is it required to arrange for the purchase and sale of any specific number or dollar amount of securities, other than to use its “reasonable best efforts” to arrange for the sale of the securities by us. Therefore, we may not sell the entire amount of securities being offered.

The terms of this offering are subject to market conditions and negotiations between us, the placement agent and prospective investors. The placement agent will have no authority to bind us by virtue of the engagement letter. This is a best efforts offering and there is no minimum amount of proceeds that is a condition to closing of this offering.

The placement agent may engage one or more sub-agents or selected dealers in connection with the offering. The ability to pursue a claim for breach of contract is material to larger purchasers in this offering as a means to enforce the following covenants uniquely available to them under the securities purchase agreement: (i) a covenant to not enter into variable rate financings for a period of     following the closing of the offering, subject to certain exceptions; and (ii) a covenant to not enter into any equity financings for     days from closing of the offering, subject to certain exceptions.

In the event that any investors that were contacted by the placement agent or were introduced to us by the placement agent during the term of our engagement agreement with the placement agent provide any capital to us in a public or private offering or other financing or capital-raising transaction of any kind (each, a “Tail Financing”) within     months following the termination or expiration of our engagement agreement with the placement agent, we shall pay the placement agent the cash and warrant compensation provided above on the gross proceeds raised in such Tail Financing from such investors.

The combined public offering price per share and accompanying Warrants and the combined public offering price per Pre-Funded Warrant and accompanying Warrants we are offering and the exercise prices and other terms of the Pre-Funded Warrants and Warrants were negotiated between us and the investors, in consultation with the placement agent based on the trading of our common stock prior to this offering, among other things. Other factors considered in determining the public offering prices of the securities we are offering and the exercise prices and other terms of the Pre-Funded Warrants and Warrants include the history and prospects of our Company, the stage of development of our business, our business plans for the future and the extent to which they have been implemented, an assessment of our management, general conditions of the securities markets at the time of the offering and such other factors as were deemed relevant.

The placement agent may be deemed to be an underwriter within the meaning of Section 2(a)(11) of the Securities Act and any fees received by it and any profit realized on the sale of the securities by it while acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act.

The following table sets forth the costs and expenses, other than placement agent fees and commissions, payable by us in connection with the sale and distribution of the securities being registered. All of the amounts shown are estimates, except for the SEC registration fee and the FINRA filing fee:

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

Our amended and restated certificate of incorporation, as amended, and our amended and restated bylaws provide for the indemnification of our directors and officers to the fullest extent permitted under the General Corporation Law of the State of Delaware. Section 102(b)(7) of the General Corporation Law of the State of Delaware permits a corporation to provide in its certificate of incorporation that a director or officer of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duties as a director or officer, except for liability for any:

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

Section 174 of the General Corporation Law of the State of Delaware provides, among other things, that a director who willfully or negligently approves of an unlawful payment of dividends or an unlawful stock purchase or redemption, may be held liable for such actions. A director who was either absent when the unlawful actions were approved or dissented at the time may avoid liability by causing his or her dissent to such actions to be entered in the books containing minutes of the meetings of the board of directors at the time such action occurred or immediately after such absent director receives notice of the unlawful acts.

As permitted by the General Corporation Law of the State of Delaware, we have entered, and continue to enter, into separate indemnity agreements with each of our directors and executive officers that require us to indemnify such persons against any and all costs and expenses (including attorneys’, witness or other professional fees) actually and reasonably incurred by such persons in connection with any action, suit or proceeding (including derivative actions), whether actual or threatened, to which any such person may be made a party by reason of the fact that such person is or was a director or officer or is or was acting or serving as an officer, director, employee or agent of ours or any of our affiliated enterprises. Under these agreements, we are not required to provide indemnification for certain matters, including:

The indemnification agreements also set forth certain procedures that will apply in the event of a claim for indemnification thereunder.

We have an insurance policy in place that covers our officers and directors with respect to certain liabilities, including liabilities arising under the Securities Act or otherwise.

Pursuant to certain underwriting agreements we may enter, the underwriters are obligated, under some circumstances, to indemnify our directors, officers and controlling persons against specified liabilities, including liabilities under the Securities Act.
