In October 2023, we issued and sold pursuant to a Securities Purchase Agreement, dated October 11, 2023 (the “Purchase Agreement”), with an institutional investor (the “Selling Securityholder”) (i) in a registered offering to the Selling Securityholder (a) $45.0 million aggregate principal amount of senior secured convertible notes due 2025 (the “Registered Notes”) initially convertible by the Selling Securityholder into 15,713,663 shares of our common stock, $0.0001 par value per share (“common stock”), and (b) warrants to purchase up to 21,660,650 shares of our common stock (the “Registered Warrants”), and (ii) in a concurrent private placement, $35.0 million aggregate principal amount of senior secured convertible notes due 2025 initially convertible by the Selling Securityholder into 12,221,738 shares of our common stock (the “Notes”). We also granted the Selling Securityholder an option to purchase up to an additional $25.0 million aggregate principal amount of Notes (the “Additional Notes”) and warrants (together with the Registered Warrants, the “Warrants”) to purchase up to 6,768,954 shares of our common stock in a subsequent private placement on substantially the same terms as the Notes and the Registered Warrants. This prospectus relates to the resale of (i) up to $35,000,000 aggregate principal amount of the Notes and (ii) up to 12,221,738 shares of common stock issuable upon conversion of the Notes (the “Shares”) by the Selling Securityholder. We will not receive any proceeds from the resale by the Selling Securityholder of the Notes and the Shares described in this prospectus.

The Notes do not bear regular interest. The Notes mature on September 1, 2025 (the “Maturity Date”), unless earlier repurchased, redeemed or converted. We sold the Notes at an issue price of 100% of the principal amount, and, as described in more detail in this prospectus, when we repay the principal of the Notes at maturity pursuant to the terms of the Notes, we will be required to pay 115% of the principal amount repaid (the “Repayment Price”). Holders of the Notes have the option to partially redeem the Notes on the first day of each month beginning November 1, 2023 for the principal amounts described in this prospectus at the Repayment Price.

Holders of the Notes may convert their Notes into shares of our common stock at any time prior to the close of business on the second scheduled trading day (or, if earlier, the standard settlement period for the primary Eligible Exchange (as defined herein) (measured in terms of trading volume for our common stock) on which the common stock is traded) immediately before the Maturity Date. The Notes are initially convertible into 349.1925 shares of our common stock per $1,000 principal amount of Notes, equivalent to an initial conversion price of approximately $2.8638 per share of our common stock.

The conversion rate will also be subject to adjustment as described in this prospectus.

Subject to certain conditions, at our option, we can require conversion of all, but not less than all, of the Notes and the Registered Notes if the last reported sale price of our common stock exceeds 175% of the conversion price for at least 20 volume-weighted average price (“VWAP”) trading days in any 30 consecutive trading day period.

Subject to terms, conditions and certain exceptions set forth in the Notes, beginning on the thirtieth day following the date that the Resale Registration Statement becomes effective, we have the right to redeem all (but not less than all) of the then outstanding principal amount of the Notes for cash at the redemption price described in this prospectus under the section titled “Description of Notes—Redemption at Our Option.” If a Fundamental Change (as defined herein) occurs the holders of the Notes may require us to repurchase the Notes and the Registered Notes for a cash amount equal to the price described in this prospectus under the section titled “Description of Notes— Repurchase of the Notes upon a Fundamental Change.”

The Notes are secured by a first-priority lien, subject only to certain permitted liens, on substantially all our and our subsidiaries’ (other than certain foreign subsidiaries) assets, whether now owned or hereafter acquired (other than certain excluded property).

As described in more detail in this prospectus, the Notes are our senior secured obligations, rank pari passu with the Registered Notes and any Additional Notes, senior in right of payment to all of our indebtedness that is expressly subordinated to the Notes in right of payment, effectively senior to all our unsecured indebtedness to the extent of the collateral securing the Notes, effectively junior to all of our indebtedness secured by permitted liens, to the extent of the value of the assets subject to such permitted liens and to the extent such permitted liens have lien priority by contract or law and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries that are not party to the security documents (as defined in “Description of Notes—Security”).

Our registration of the securities covered by this prospectus does not mean that the Selling Securityholder will offer or sell any of the Notes or the Shares. See the section entitled “Plan of Distribution” for additional information about how the Selling Securityholder may sell or otherwise dispose the Notes or the Shares. See the section entitled “Selling Securityholder” for additional information regarding the Selling Securityholder.

Our common stock is listed on The Nasdaq Capital Market (“Nasdaq”) under the symbol “BNGO.” On November 7, 2023, the last reported sale price on Nasdaq of our common stock was $1.43 per share. There is currently no established trading market for the Notes, and we do not expect a market to develop. We do not intend to list the Notes on Nasdaq or any other national securities exchange or any other nationally recognized trading system. Without an active trading market, the liquidity of the Notes will be limited.

We are a “smaller reporting company” as defined under the federal securities laws and, as such, have elected to comply with certain reduced reporting requirements for this prospectus and may elect to do so in future filings.

This could cause the value of our securities to decline, and you may lose all or part of your investment.

Our operations have consumed substantial amounts of cash since our inception. We expect to continue to spend substantial amounts of cash in order to continue the commercialization of our products and technologies, fund our research and development programs and execute potential strategic transactions. In connection with the preparation of our financial statements for the fiscal year ended December 31, 2022, we had performed an analysis of our ability to continue as a going concern and, based on our current business plan, we believed that our existing cash and cash equivalents will not be sufficient for the next twelve months from the issuance of our report for the fiscal year ended December 31, 2022. Our ability to execute our operating plan depends on our ability to generate sales and obtain additional funding through equity offerings, debt financings or potential licensing and collaboration arrangements. For example, we will likely need to raise substantial additional capital to:

Our future funding requirements will be influenced by many factors, including:

As of June 30, 2023, we had $77.1 million in cash, cash equivalents and short-term investments. We received net proceeds of approximately $75.6 million, after deducting placement agent fees and offering expenses from the issuance and sale of our securities to the Selling Securityholder pursuant to the Purchase Agreement in October 2023. Based on our current business plans, we believe the net proceeds together with our existing cash, cash equivalents and short-term investments, will be sufficient to fund our operating expenses and capital expenditure requirements through at least 2024. However, this estimate assumes the inclusion of $35.0 million that we are required to hold as restricted cash in the Restricted Cash Account (as defined in “Description of Notes—Funding Conditions”), which cash may only be released from such account upon the satisfaction of the Funding Conditions (as defined in “Description of Notes—Funding Conditions”). We expect the Funding Conditions may be difficult to achieve, and there is no assurance that we will be able to meet these Funding Conditions and access such restricted cash. Excluding this amount of restricted cash, our existing cash, cash equivalents and short-term investments will only be sufficient to fund our operating expenses and capital expenditure requirements through at least into the third quarter of 2024. In either situation, our existing cash and cash equivalents and available-for-sale securities, will not be sufficient for us to achieve cash-flow break even and we expect to need to seek additional capital based on favorable market conditions or strategic considerations alternatives in the future.

We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect, requiring us to seek additional funds sooner than planned, through public or private equity or debt financings or other sources, such as strategic collaborations. The various ways we could raise additional capital carry potential risks. We cannot assure you that we will be able to obtain additional funds on acceptable terms, or at all. If we raise additional funds by issuing equity or equity-linked securities, our stockholders may experience dilution. Any equity or debt securities we issue could provide for rights, preferences, or privileges senior to those of holders of our common stock. Future debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. Any debt or equity financing may contain terms that are not favorable to us or our stockholders. If we raise additional funds through collaboration and licensing arrangements with third parties, it may be necessary to relinquish some rights to our technologies or our products, or grant licenses on terms that are not favorable to us. In addition, we may not be able to access a portion of our existing cash, cash equivalents and investments or “restricted cash” in the account control agreement due to market conditions such as recent and potential future disruptions in access to bank deposits or lending commitments due to bank failures.

Global economic conditions have been worsening, with disruptions to, and volatility in, the credit and financial markets in the U.S. and worldwide resulting from the effects of ongoing geopolitical or macroeconomic developments. If these conditions persist or worsen, we could experience an inability to access additional capital. If we do not have, or are not able to obtain, sufficient funds, we may have to delay development or

commercialization of our technologies and products. We also may have to reduce marketing, customer support or other resources devoted to our products or technologies or cease operations. Any of these factors could have a material adverse effect on our financial condition, operating results and business. Any of the foregoing could significantly harm our business, prospects, financial condition and results of operation and could cause the price of our securities to decline. Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to conduct our strategic operations.

The Notes rank pari passu with the Registered Notes and any Additional Notes, senior in right of payment to all of our indebtedness that is expressly subordinated to the Notes in right of payment, effectively senior to all our unsecured indebtedness to the extent of the collateral securing the Notes, effectively junior to all of our indebtedness secured by permitted liens, to the extent of the value of the assets subject to such permitted liens and to the extent such permitted liens have lien priority by contract or law and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries that are not party to the security documents. If we acquire or form a subsidiary, other than certain foreign subsidiaries exempted under the terms of the Notes, such subsidiary will be required to become a party to the security documents within 30 days. In the event of our bankruptcy, liquidation, reorganization or other winding up, the assets of our subsidiaries that are not party to the security documents will be available to pay obligations on the Notes only after all indebtedness and other liabilities (including trade payables) of such subsidiaries have been repaid in full.

The Notes and the Purchase Agreement contain a number of restrictive covenants that impose significant operating and financial restrictions on us and may limit our ability to engage in acts that may be in our long-term best interest. In particular, the Notes contain customary affirmative and negative covenants (including covenants that limit our ability to incur debt, make investments, transfer assets, engage in certain transactions with affiliates and merge with other companies, in each case, other than those permitted by the Notes, and that require us to maintain a share reserve in respect of the Notes and warrants that we issued in connection with the Registered Notes) and events of default, and the Purchase Agreement contains customary covenants (including covenants that limit our ability to issue additional securities during specified periods and enter into variable rate transactions, and that require us to maintain a share reserve in respect of the Notes and warrants that we issued in connection with the Registered Notes). Furthermore, we will be required to maintain: (A) cash and cash equivalents subject to account control agreements in favor of the Selling Securityholder in a minimum amount equal to the greater of (i) $30 million and (ii) the lesser of (x) $50 million and (y) our trailing six-month cash burn rate (calculated in the manner set forth in the Notes); (B) an “at the market” program, equity line of credit, or similar program approved by the Selling Securityholder with aggregate available, accessible and unused capacity to generate gross proceeds to us of at least $50 million; and (C) beginning with the fiscal quarter ending March 31, 2024, our and our wholly owned subsidiaries’ Available Cash (as defined under “Description of Notes——Certain Covenants—Minimum Liquidity”) on the last calendar day of each quarter shall be greater than or equal to (x) our and our wholly owned subsidiaries’ cash and cash equivalents on the last day of the immediately preceding fiscal quarter, less (y) $30 million. Our ability to meet the financial tests under the Notes can be affected by events beyond our control, and we may be unable to meet them. The Registered Notes and the Additional Notes, if any, contain similar provisions restricting our current and future operations.

A breach of the covenants or restrictions under the Purchase Agreement, the Notes, the Registered Notes and the Additional Notes, if any, or under the agreements governing any of our other permitted indebtedness could result in an event of default under the applicable indebtedness. Such a default may allow holders of the Notes, the Registered Notes and the Additional Notes, if any, or the holders or lenders of our other permitted indebtedness, as applicable, to accelerate the related indebtedness, which may result in the acceleration of other indebtedness to which a cross-acceleration or cross-default provision applies. In addition, such lenders or holders could terminate commitments to lend money, if any. Furthermore, if we were unable to repay the Notes, the Registered Notes and the Additional Notes, if any, or other permitted indebtedness then due and payable, secured

lenders could proceed against the assets, if any, securing such indebtedness. In the event such lenders or holders accelerate the repayment of the Notes, the Registered Notes and the Additional Notes, if any, or our other permitted borrowings, we may not have sufficient assets to repay that indebtedness. A default would also likely significantly diminish the market price of our common stock. Furthermore, as a result of these restrictions, we may be limited in how we conduct and grow our business, be unable to compete effectively or be unable to take advantage of new business opportunities. These restrictions may affect our ability to grow in accordance with our strategy.

Our ability to make scheduled payments of principal or default interest, if any, or to refinance the Notes or our other permitted indebtedness, including the Registered Notes and the Additional Notes, if any, depends on our future performance, which is subject to economic, financial, competitive and other factors, some of which are beyond our control. After giving effect to the issuance of the Notes and the Registered Notes, our and our subsidiaries’ outstanding indebtedness is approximately $80.0 million, and the terms of the Notes and the Registered Notes require us to pay approximately $92.0 million to repay the full principal amount of the Notes and the Registered Notes at maturity. Our business may not continue to generate cash flow from operations in the future sufficient to satisfy our obligations under the Notes or our other permitted indebtedness. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as reducing or delaying investments or capital expenditures, selling assets, refinancing or obtaining additional equity capital on terms that may be onerous or highly dilutive. We may only prepay the Notes, including the Registered Notes and the Additional Notes, if any, in full without the consent of the holders under certain circumstances, and our ability to refinance the Notes or our other permitted indebtedness will also depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on the Notes or our other indebtedness, including the Registered Notes and the Additional Notes, if any.

The proceeds of any sale of collateral securing the Notes following an Event of Default with respect thereto may not be sufficient to satisfy, and may be substantially less than, amounts due on the Notes.

No appraisal of the value of the collateral securing the Notes has been made. The value of the collateral in the event of liquidation will depend upon market and economic conditions, the availability of buyers and similar factors. The value of the collateral could be impaired in the future as a result of changing economic and market conditions, our failure to successfully implement our business strategy, competition and other factors. By its nature, some or all of the collateral may not have a readily ascertainable market value or may not be saleable or, if saleable, there may be substantial delays in its liquidation.

Bankruptcy laws and other laws relating to foreclosure and sale also could substantially delay or prevent the ability of the collateral agent for the Selling Securityholder under the Notes (the “Collateral Agent”), or any holder of the Notes to obtain the benefit of any collateral securing the Notes. Such delays could have a material adverse effect on the value of the collateral.

If the proceeds of any sale of collateral are not sufficient to repay all amounts due on the Notes, the holders of the Notes (to the extent not repaid from the proceeds of the sale of the collateral) would have only an unsecured claim against our remaining assets.

The Notes and the security documents permit certain liens and exclude certain assets from the collateral. If an Event of Default occurs and the Notes are accelerated, the Notes will be equal in right of payment with our permitted senior indebtedness with respect to such excluded assets and will be effectively subordinated to holders of obligations secured by a lien on such excluded assets.

The collateral securing the Notes is subject to certain exceptions, defects, encumbrances, liens and other imperfections permitted by the Notes and the related security documents, whether existing on or after the date

the Notes were issued. The existence of any such exceptions, defects, encumbrances, liens and other imperfections could adversely affect the value of the collateral securing the Notes as well as the ability of the Collateral Agent to realize or foreclose on such collateral. Additionally, future regulatory developments or other inabilities to obtain or comply with the required licenses or approvals may adversely affect the value of the collateral. In the event of foreclosure, the transfer of such licenses or other approvals may be prohibited, may not be possible or may require us to incur significant cost and expense. If the regulatory authorizations required for such transfers are not obtained or are delayed, the foreclosure may be delayed and the value of the collateral may be significantly impaired. The security interest of the Collateral Agent is subject to practical challenges generally associated with the realization of security interests in collateral. For example, additional filings and/or the consent of a third party may be required in connection with obtaining or enforcing a security interest in an asset. If we are unable to obtain these consents or make these filings, the security interests may be invalid and the holders will not be entitled to the benefits of the security interests in the collateral or any recovery with respect to the sale of such collateral. We cannot assure you that these filings will be made or any such consent of any third parties will be given when required to create a lien or facilitate a foreclosure on such assets. As a result, the Collateral Agent may not have the ability to foreclose upon those assets and the value of the collateral may be significantly impaired as a result, or the security interests may be invalid and the holders of the Notes will not be entitled to the collateral or any recovery with respect thereto.

The right of the Collateral Agent for the Notes to repossess and dispose of the collateral securing the Notes upon acceleration is likely to be significantly impaired by federal bankruptcy law if bankruptcy proceedings are commenced by or against us prior to or possibly even after the Collateral Agent has repossessed and disposed of the collateral. Under Chapter 7, Title 11 of the United States Code (the “United States Bankruptcy Code”), a secured creditor, such as the Collateral Agent for the Notes, is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from a debtor, without bankruptcy court approval, which may not be given. Moreover, applicable federal bankruptcy law permits the debtor to continue to retain and to use collateral, and the proceeds, products, rents or profits of the collateral, even though the debtor is in default under the applicable debt instruments, provided that the secured creditor is given “adequate protection.” The meaning of the term “adequate protection” may vary according to circumstances, but it is intended in general to protect the value of the secured creditor’s interest in the collateral as of the commencement of the bankruptcy case and may include cash payments or the granting of additional security, if and at such time as the bankruptcy court in its discretion determines, for any diminution in the value of the collateral as a result of the stay of repossession or disposition or any use of the collateral by the debtor during the pendency of the bankruptcy case. A bankruptcy court may determine that a secured creditor may not require compensation for a diminution in the value of its collateral if the value of the collateral exceeds the debt it secures.

In view of the broad discretionary powers of a bankruptcy court, it is impossible to predict how long payments under the Notes could be delayed following commencement of a bankruptcy case, whether or when the Collateral Agent would repossess or dispose of the collateral, or whether or to what extent holders of the Notes would be compensated for any delay in payment or loss of value of the collateral through the requirements of “adequate protection.” Furthermore, in the event the bankruptcy court determines that the value of the collateral is not sufficient to repay all amounts due on the Notes, the holders of the Notes would have “under secured claims” as to the difference. Federal bankruptcy laws do not permit the payment or accrual of interest, costs and attorneys’ fees for “under-secured claims” during the debtor’s bankruptcy case.

If we are subject to any bankruptcy proceeding, it is possible that the bankruptcy trustee, the debtor-in-possession or competing creditors will assert that the fair market value of the collateral with respect to the Notes on the date of the bankruptcy filing was less than the then-current principal amount of the Notes. Upon a finding by the bankruptcy court that the Notes are under-collateralized, the claims in the bankruptcy proceeding with respect to the Notes would be bifurcated between a secured claim and an unsecured claim, and the unsecured claim would not be entitled to the benefits of security in the collateral. Other consequences of a finding of under-collateralization would be, among other things, a lack of entitlement on the part of the Notes to

receive post-petition interest and a lack of entitlement on the part of the unsecured portion of the Notes to receive “adequate protection” under federal bankruptcy laws. In addition, if any payments of post-petition interest had been made at any time prior to such a finding of under-collateralization, those payments would be recharacterized by the bankruptcy court as a reduction of the principal amount of the secured claim with respect to the Notes.

In the event of a bankruptcy, liquidation, dissolution, reorganization or similar proceeding against us, holders of the Notes will only be entitled to post-petition interest under the United States Bankruptcy Code to the extent that the value of their security interest in the collateral is greater than their pre-bankruptcy claim. Holders of the Notes that have a security interest in collateral with a value equal or less than their pre-bankruptcy claim will not be entitled to post-petition interest under the United States Bankruptcy Code. No appraisal of the fair market value of the collateral was prepared in connection with the offering of the Notes and we therefore cannot assure you that the value of the holders’ interest in the collateral equals or exceeds the principal amount of the Notes.

Any future pledge of collateral, or any future perfection of any other pledge, to secure the Notes might be avoidable under the U.S. bankruptcy preference laws by the pledgor (as debtor in possession), by its trustee in bankruptcy or by someone else acting on behalf of the bankruptcy estate, if certain events or circumstances exist or occur, including, among others, if the pledgor is insolvent at the time of the pledge, the pledge permits the holders of the Notes to receive a greater recovery than they would in a liquidation case under the United States Bankruptcy Code, if the pledge had not been given, and a bankruptcy proceeding in respect of the pledgor is commenced within 90 days following the later of the pledge, and perfection of the pledge, or, in certain circumstances, a longer period. If any pledges of collateral are avoided, the collateral will not be available to the holders of the Notes to satisfy the obligations under the Notes. Certain payments on the Notes might be avoidable under the U.S. bankruptcy preference laws by us (as debtor in possession), by our trustee in bankruptcy or by someone else acting on behalf of the bankruptcy estate if certain events or circumstances exist or occur, including, among others, if we are insolvent at the time of the payment, the payment permits the holders of the Notes to receive a greater recovery than they would have received in a liquidation case under the United States Bankruptcy Code if the payment had not been made, and a bankruptcy proceeding in respect of us commenced within 90 days following the payment, or, in certain circumstances, a longer period.

Applicable law requires that a security interest in certain tangible and intangible assets can only be properly perfected and its priority retained through certain actions undertaken by the secured party. The liens on the collateral securing the Notes may not be perfected if we or the Collateral Agent are not able to take the actions necessary to perfect any of these liens. We have limited obligations to perfect the security interest of the holders of the Notes in specified collateral. Applicable law requires that certain property and rights acquired after the grant of a general security interest, such as certain proceeds, can only be perfected at the time such property and rights are acquired and identified. If we become subject to a bankruptcy proceeding, any collateral perfected after October 13, 2023 faces a greater risk of being invalidated than if they had been perfected on the closing date for the offering of the Registered Notes and the Notes. In addition, the Collateral Agent may not monitor, or we may fail to inform the Collateral Agent of, the future acquisition of property and rights that constitute collateral, and necessary action may not be taken to properly perfect the security interest in such after-acquired collateral. The Collateral Agent for the Notes has no obligation to monitor the acquisition of additional property or rights that constitute collateral or the perfection of any security interest in favor of the Notes against third parties. Such failure may result in the loss of the security interest therein or the priority of the security interest in favor of the Notes against third parties.

We maintain insurance or otherwise insure against hazards in a manner appropriate and customary for our business. There are, however, certain losses that may be either uninsurable or not economically insurable, in whole or in part. Insurance proceeds may not compensate us fully for our losses. If there is a complete or partial loss of any of the pledged collateral, the insurance proceeds may not be sufficient to satisfy all of the secured obligations, including obligations under the Notes.

Upon the occurrence of a Fundamental Change, holders of the Notes have the right to require us to repurchase their Notes. Events constituting a “Fundamental Change” include (a) any “person” or “group” (within the meaning of Section 13(d)(3) of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”)), other than us or our wholly-owned subsidiaries, our employee benefit plans or those of our wholly-owned subsidiaries or a holder of Notes or any of its affiliates (including a “group” including such holder or any of its affiliates) has become and files any report with the SEC indicating that such person or group has become the direct or indirect beneficial owner of the majority of the voting power of our common stock; provided, however, that, for these purposes, no “person” or “group” will be deemed to be the beneficial owner of any securities tendered pursuant to a tender or exchange offer made by or on behalf of such “person” or “group” until such tendered securities are accepted for purchase or exchange under such offer; (b) the consummation of any sale, lease or other transfer of all or substantially all of our assets, or any transfer or transaction which results in effectively the same; (c) the approval by our stockholders of a plan or proposal to liquidate or dissolve us; or (d) our common stock ceases to be listed on any Eligible Exchange (as defined and described under “Description of Notes—Repurchase of the Notes upon a Fundamental Change”). However, the Fundamental Change provisions will not afford protection to holders of the Notes in the event of other transactions that could adversely affect the Notes. For example, transactions such as leveraged recapitalizations, refinancings, restructurings, or acquisitions initiated by us may not constitute a Fundamental Change requiring us to repurchase the Notes. In the event of any such transaction, the holders would not have the right to require us to purchase the Notes, even though each of these transactions could increase the amount of our indebtedness, or otherwise adversely affect our capital structure or any credit ratings, thereby adversely affecting the holders of the Notes.

Following a Fundamental Change as described under “Description of Notes—Repurchase of the Notes upon a Fundamental Change,” holders of Notes will have the right to require us to repurchase their Notes for cash. A Fundamental Change may also constitute an event of default or prepayment under, and result in the acceleration of the maturity of, our other then-existing permitted indebtedness. We cannot assure you that we will have sufficient financial resources, or will be able to arrange financing, to pay the Fundamental Change Repurchase Price in cash with respect to any Notes surrendered by holders for repurchase upon a Fundamental Change. In addition, restrictions in our then-existing permitted indebtedness may not allow us to repurchase the Notes upon a Fundamental Change. Our failure to repurchase the Notes upon a Fundamental Change when required would result in an Event of Default with respect to the Notes, which could, in turn, constitute a default under the terms of our other permitted indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the Notes.

The conversion rate of the Notes is subject to adjustment for certain events, including, but not limited to, certain dividends on our common stock, the issuance of certain rights, options or warrants to holders of our common stock, subdivisions or combinations of our common stock, certain distributions of assets, debt securities, capital stock, cash or other property to holders of our common stock and certain tender or exchange offers, as described under the section titled “Description of Notes—Conversion Rights” in this prospectus. The conversion rate will not be adjusted for other events, such as an issuance of our common stock for cash, that may adversely affect the trading price of the Notes and the market price of our common stock. An event may occur that is adverse to the interests of the holders of the Notes and their value, but that does not result in an adjustment to the conversion rate.

Notwithstanding anything to the contrary herein, you will not be entitled to receive any shares of our common stock otherwise deliverable upon conversion of the Notes to the extent, but only to the extent, that such receipt would cause you to become, directly or indirectly, the “beneficial owner” (as defined under “Description

of Notes—Certain Definitions”) of more than 4.99% of the shares of our common stock outstanding at such time. However, you may increase or decrease such percentage to any other percentage not in excess of 9.99%; provided that any increase in such percentage shall not be effective until 61 days after such notice to us. Any purported delivery of shares of our common stock upon conversion of the Notes shall be void and have no effect to the extent, but only to the extent, that such delivery would result in any person becoming the beneficial owner of shares of our common stock outstanding at such time in excess of the beneficial ownership limits then applicable to such person; provided, however that, in the event of a forced conversion (as described in “Description of Notes—Forced Conversion”), the aggregate number of shares of common stock that would otherwise be required to be issued to such holder shall be held in abeyance for the benefit of such holder until such time or times as its right thereto would not result in such holder exceeding the applicable beneficial ownership limitation.

As a result of the beneficial ownership limits, shares otherwise deliverable upon conversion of a holder’s Notes may be delayed, or never delivered at all. These limitations on beneficial ownership may force a holder to sell shares of our common stock or other securities it owns in order to receive shares such holder would otherwise be entitled to receive upon conversion. If a holder converts its Notes and does not receive any shares otherwise deliverable upon conversion of its Notes, we will not be responsible for any lost value due to a delayed delivery, or if they are never delivered as a result of the conversion restrictions described above.

The conversion of the Registered Notes and the Notes, and exercise of the Registered Warrants of which this prospectus forms a part, will dilute the ownership interests of existing stockholders to the extent we deliver shares upon conversion of the Notes or exercise of the Registered Warrants. In addition, if the Selling Securityholder exercises its option to purchase the Additional Notes and warrants, this will dilute the ownership interests of existing stockholders further to the extent we deliver shares upon conversion of the Additional Notes and exercise of the warrants. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the Registered Notes, Notes and Registered Warrants may encourage short selling by market participants because the conversion of the Registered Notes or Notes and exercise of the Registered Warrants could be used to satisfy short positions, or anticipated conversion of the Registered Notes or Notes or exercise of the Registered Warrants into shares of our common stock could depress the price of our common stock.

Under the Notes, a converting holder will be exposed to fluctuations in the value of our common stock during the period from the date such holder surrenders the Notes for conversion until the date we settle our conversion obligation. We will deliver the consideration due in respect of conversion on the second business day immediately following the relevant conversion date. Accordingly, if the price of our common stock decreases during this period, the amount and/or value of consideration a holder receives will be adversely affected.

The terms of the Notes require us to repurchase the Notes in the event of a Fundamental Change. A takeover of our company would trigger an option of the holders of the Notes to require us to repurchase the Notes. This may have the effect of delaying or preventing a takeover of our company that would otherwise be beneficial to investors in the Notes or shares of our common stock.

Holders of the Notes will not be entitled to certain rights with respect to our common stock (including, without limitation, voting rights) but holders of the Notes will be subject to all changes affecting our common stock. Holders of the Notes will not be entitled to the rights of the common stock underlying such Notes, except to the extent they convert such Notes, and, in such case, will be deemed to be the record holder of such shares

of common stock as of the related conversion date. For example, if an amendment is proposed to our certificate of incorporation or bylaws requiring stockholder approval and the record date for determining the stockholders of record entitled to vote on the amendment occurs prior to the conversion date of any Note, then the holder of such Note will not be entitled to vote the shares due upon conversion on the amendment, although such holder will, upon conversion, nevertheless be subject to any changes affecting our common stock.

The conversion rate of the Notes is subject to adjustment in certain circumstances, including the payment of cash dividends. If the applicable conversion rate is adjusted as a result of a distribution that is taxable to our common stockholders, such as a cash dividend, a holder of the Notes may be deemed to have received a dividend subject to U.S. federal income tax without the receipt of any cash. In addition, a failure to adjust (or to adjust adequately) the applicable conversion rate after an event that increases a holder’s proportionate interest in us could be treated as a deemed taxable dividend to the holder. See the section titled “Material U.S. Federal Income Tax Consequences.”

There has not been and there is no trading market for the Notes, and we do not intend to apply to list the Notes on any securities exchange or to arrange for quotation on any automated dealer quotation system. As a result, we cannot assure you that an active trading market will develop for the Notes. If an active trading market does not develop or is not maintained, the market price and liquidity of the Notes may be adversely affected. In that case holders may not be able to sell their Notes at a particular time or they may not be able to sell their Notes at a favorable price.

Our stock price has been and may continue to be volatile. The daily closing market price for our common stock has varied significantly in the last 12 months, ranging between a high price of $28.10 on November 15, 2022 and a low price of $1.26 on October 27, 2023. During this time, the price per share of common stock has ranged from an intra-day low of $1.20 per share to an intra-day high of $30.10 per share.

The trading price of our securities is likely to be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control, including limited trading volume. We cannot predict the actions of market participants and, therefore, can offer no assurances that the market for our common stock will be stable or appreciate over time. The market price of our common stock may be influenced by many factors, including but not limited to:

As a result, you may not be able to sell your shares of our common stock at or above the price at which you purchase them. In addition, the stock market in general, and the market for life science technology

companies in particular (including companies in the diagnostic, genomic and biotechnology related sectors), have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our securities, regardless of our actual operating performance. In the past, securities class action litigation has often been instituted against companies following periods of volatility in the market price of a company’s securities. Because of the volatility of our stock price, we may become the target of securities litigation in the future. This type of litigation, if instituted, could result in substantial costs and a diversion of management’s attention and resources, which would harm our business, operating results or financial condition.

At our 2023 Annual Meeting of Stockholders, our stockholders approved a proposal for a series of alternate amendments to our Amended and Restated Certificate of Incorporation, as amended, to effect, at the option of our board of directors, a reverse stock split of our common stock at a ratio between 1-for-5 and 1-for-10, inclusive, as determined by our board of directors in its sole discretion. On August 2, 2023, our board of directors approved a reverse stock split at a ratio of 1-for-10, and on August 4, 2023, we filed a certificate of amendment to effect the reverse split ratio chosen by our board of directors. We cannot assure you that we will achieve any of the intended results of the reverse stock split, including improved marketability and liquidity of our common stock, maintaining compliance with Nasdaq listing standards and encouraging trading in our common stock by long-term investors. Accordingly, the market price and the value of your investment could be materially and negatively impacted.

The total number of authorized shares of our common stock will remain the same as before the reverse stock split discussed in the above risk factor. The reverse stock split increased the number of shares of our common stock (or securities convertible or exchangeable for our common stock) available for issuance by decreasing the number of shares of our common stock issued and outstanding. The additional available shares are available for issuance from time to time at the discretion of our board of directors when opportunities arise, without further stockholder action, except as may be required for a particular transaction by law, the rules of any exchange on which our securities may then be listed, or other agreements or restrictions. Any issuance of additional shares of our common stock would increase the number of outstanding shares of our common stock and (unless such issuance was pro-rata among all existing stockholders) the percentage ownership of existing stockholders would be diluted accordingly. In addition, any such issuance of additional shares of our common stock could have the effect of diluting the earnings per share and book value per share of outstanding shares of our common stock.

Additionally, such effective increase in the number of shares of our common stock available for issuance could, under certain circumstances, have anti-takeover implications. For example, without further stockholder approval, our board of directors could adopt a “poison pill” which would, under certain circumstances related to an acquisition of our securities that is not approved by the board of directors, give certain holders the right to acquire additional shares of our common stock at a low price. Our board of directors also could strategically sell shares of common stock in a private transaction to purchasers who would oppose a takeover or favor the current board of directors. Although the reverse stock split was prompted by business and financial considerations, you should be aware the reverse stock split could facilitate future efforts by us to deter or prevent changes in control, including transactions in which you might otherwise receive a premium for your shares over then current market prices.

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 Nasdaq 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 the Company’s common stock of $1.00 per share.

In the past, we have failed to comply with the per share minimum required for continued listing on Nasdaq pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”). On May 30, 2023, we received a letter (the “Notice”) from Nasdaq advising us that for 30 consecutive trading days preceding the date of the Notice, the bid price of our common stock had closed below the Minimum Bid Price Requirement. The Notice has no effect on the listing of our common stock at this time, and our common stock continues to trade on Nasdaq under the symbol “BNGO.”

Under Nasdaq Listing Rule 5810(c)(3)(A), we have 180 calendar days following the date of the Notice to regain compliance with the Minimum Bid Price Requirement. If at any time during this 180-day period the closing bid price of our common stock is at least $1.00 for a minimum of 10 consecutive business days, we will regain compliance with the Minimum Bid Price Requirement and the matter will be closed.

If we do not regain compliance with the Minimum Bid Price Requirement within the applicable compliance period, our common stock will be subject to delisting. In addition, if we fail to satisfy another Nasdaq requirement for continued listing, Nasdaq staff could provide notice that our common stock may become subject to delisting.

While we implemented a reverse stock split, effective August 4, 2023, to attempt to regain compliance with the Minimum Bid Price Requirement, we cannot assure you that the reverse stock split will allow us to successfully regain compliance with the Minimum Bid Price Requirement, or that such an event leading to notice from Nasdaq staff will not happen and, if it does, that we will be able to regain compliance. 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 implications, 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; for example, a delisting for a period of at least five Trading Days constitutes an Event of Default under the Registered Notes and the Notes, which entitles the holder thereof to declare the Registered Notes or Notes (as applicable) immediately due and payable in an amount equal to the Event of Default Acceleration Amount (as defined below) as described in “Description of Notes—Acceleration Upon Event of Default and Event of Default Stock Payments.” Delisting could also cause a loss of confidence of our customers, collaborators, vendors, suppliers and employees, which could harm our business and future prospects.

Our executive officers, directors and 5% stockholders and their affiliates currently beneficially own a significant percentage of our outstanding voting stock. These stockholders may be able to determine all matters requiring stockholder approval. For example, these stockholders may be able to control elections of directors, amendments of our organizational documents, or approval of any merger, sale of assets or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our securities that you may feel are in your best interest as one of our stockholders.

We currently qualify as a smaller reporting company and a non-accelerated filer, which allows us to take advantage of many exemptions from various reporting requirements that are applicable to other public companies that are not smaller reporting companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, but we still expect to incur substantial legal and financial compliance costs. As we have chosen to avail ourselves of certain scaled disclosure requirements applicable to smaller reporting companies, the content of our disclosures may differ from period to period. We may no longer qualify as a smaller reporting company in the future should the market value of our common stock held by non-affiliates as of the end of the second quarter of any given year once again exceed

$700.0 million or our revenue as of the end of any fiscal year exceed $100.0 million. There may be further variance in the content of our disclosures as we avail ourselves of certain scaled disclosure requirements if we subsequently no longer qualify as a smaller reporting company because we would be required to provide the full disclosures required of non-smaller reporting companies. We cannot predict if investors will find our securities less attractive because we rely on these exemptions, which could result in a less active trading market for our securities and increased volatility in the price of our securities.

Sales of a substantial number of shares of our common stock in the public market could occur at any time, subject to the restrictions and limitations described below. If our stockholders sell, or the market perceives that our stockholders intend to sell, substantial amounts of our common stock in the public market, the market price of our common stock could decline significantly. All of our outstanding shares of common stock are available for sale in the public market, subject only to the restrictions of Rule 144 under the Securities Act in the case of our affiliates.

In addition, as of the date of this registration statement, we have filed registration statements on Form S-8 under the Securities Act registering the issuance of an aggregate of 5,286,720 shares of common stock subject to options or other equity awards issued or reserved for future issuance under our equity incentive plans. We also intend to file future registration statements on Form S-8 under the Securities Act registering the issuance of additional shares of common stock as the number of shares that may be issued under certain employee equity benefit plans automatically increase due to “evergreen” provisions. Shares registered under these registration statements on Form S-8 are available for sale in the public market subject to vesting arrangements and exercise of options, the lock-up agreements described above and the restrictions of Rule 144 in the case of our affiliates.

Our amended and restated certificate of incorporation and amended and restated bylaws, contain provisions that could delay or prevent a change of control of our company or changes in our board of directors that our stockholders might consider favorable. Some of these provisions include:

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the General Corporation Law of the State of Delaware, which may prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock. These anti-takeover provisions and other provisions in our amended and restated certificate of incorporation and amended and restated bylaws could make it more difficult for stockholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed by the then-current board of directors and could also delay or impede a merger, tender offer or proxy contest involving our company. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing or cause us to take other corporate actions you desire. Any delay or prevention of a change of control transaction or changes in our board of directors could cause the market price of our securities to decline.

Since inception, we have experienced recurring operating losses and negative cash flows from operating activities, and have significant accumulated deficit. We expect to continue to generate operating losses and consume significant cash resources for the foreseeable future. Without additional financing, these conditions raise substantial doubt about our ability to continue as a going concern, meaning that we may be unable to continue operations for the foreseeable future or realize assets and discharge liabilities in the ordinary course of operations. As a result, our financial statements include an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. If we are unable to obtain sufficient funding, our business, prospects, financial condition and results of operations will be materially and adversely affected and we may be unable to continue as a going concern. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our consolidated financial statements, and it is likely that investors will lose all or a part of their investment. Future reports from our independent registered public accounting firm may also contain statements expressing doubt about our ability to continue as a going concern. If we seek additional financing to fund our business activities in the future and there remains doubt about our ability to continue as a going concern, investors or other financing sources may be unwilling to provide additional funding on commercially reasonable terms or at all.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law:

This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act. Furthermore, Section-22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our amended and restated certificate of incorporation further provides that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, we would

expect to vigorously assert the validity and enforceability of the exclusive forum provisions of our amended and restated certificate of incorporation. This may require significant additional costs associated with resolving such action in other jurisdictions and there can be no assurance that the provisions will be enforced by a court in those other jurisdictions.

These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage lawsuits against us and our directors, officers and other employees. If a court were to find either exclusive-forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could adversely affect our results of operations and financial condition.

Our shares of common stock began trading on Nasdaq on September 21, 2018. Given the limited trading history of our common stock, there is a risk that an active trading market for our shares will not be sustained, which could put downward pressure on the market price of our common stock and thereby affect the ability of our stockholders to sell their shares.

We will not receive any of the proceeds from the sale by the Selling Securityholder of the Notes or Shares in this offering. The Selling Securityholder will receive all of the proceeds from the sale of the Notes or Shares hereunder.

The following description of our capital stock, certain provisions of our certificate of incorporation and bylaws, and certain provisions of Delaware law are summaries. The following description is not complete and is subject to and qualified in its entirety by our certificate of incorporation and bylaws, which are filed as exhibits to the registration statement of which this prospectus is a part, as well as the relevant provisions of the General Corporation Law of the State of Delaware.

As of the date of this prospectus, our certificate of incorporation authorized 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 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. Our amended and restated certificate of incorporation, as amended, 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 our certificate of incorporation 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. We have no current plans to issue any shares of preferred stock.

We are subject to Section 203 of the General Corporation Law of the State of Delaware. Section 203 generally prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

Section 203 of the DGCL defines a business combination to include:

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

Among other things, our amended and restated certificate of incorporation, as amended, and amended and restated 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 the success of any attempt to change our control.

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.

We are subject to Section 203 of the General Corporation Law of the State of Delaware, 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, subject to certain exceptions.

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

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

The following is a summary of the material terms and provisions of the Notes that are being offered hereby. This summary is subject to and qualified in its entirety by the form of Note and related security documents, each of which were filed with the SEC as an exhibit to a Current Report on Form 8-K filed by us and incorporated by reference into the registration statement of which this prospectus forms a part. You should carefully review the terms and provisions of the form of Note and related security documents for a complete description of the terms and conditions of the Notes. See the sections titled “Where You Can Find More Information” and “Incorporation of Certain Information by Reference” in this prospectus.

We issued the $35,000,000 aggregate principal amount of the Notes pursuant to the Purchase Agreement as a series of our senior debt securities to the Selling Securityholder.

For purposes of this summary, the terms “Company”, “we”, “us” and “our” refer only to Bionano Genomics, Inc. and not to any of our subsidiaries.

The Notes are our senior secured obligations. We issued $35,000,000 aggregate principal amount of the Notes on October 13, 2023 (the “Closing Date”) in a private placement exempt from the registration requirements of the Securities Act. We sold the Notes to the Selling Securityholder pursuant to the Purchase Agreement at an issue price of 100.00% of their principal amount.

The entire principal amount of the Notes will mature and become due and payable on September 1, 2025, unless earlier repurchased, redeemed or converted. On the maturity date, we will pay the holders an amount of cash equal to 115% for the then-outstanding principal amount of the Notes (the “Maturity Principal Amount”) plus any accrued and unpaid interest on the Notes.

The Notes are not subject to any sinking fund provision.

The Selling Securityholder has the option to purchase up to an additional $25,000,000 aggregate principal amount of the senior secured convertible notes due 2025 in a private placement exempt from the registration requirements of the Securities Act, on substantially the same terms as the Notes being offered by this prospectus (the “Additional Notes”).

As described below under “—Security,” the Notes are our senior secured obligations, are pari passu with the Registered Notes and any Additional Notes, senior in right of payment to all of our indebtedness that is expressly subordinated to the Notes in right of payment, effectively senior to all our unsecured indebtedness to the extent of the collateral securing the Notes, effectively junior to all of our indebtedness secured by permitted liens, to the extent of the value of the assets subject to such permitted liens and to the extent such permitted liens have lien priority by contract or law and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries that are not party to the security documents (as defined in “—Security”). If we acquire or form a subsidiary, other than certain foreign subsidiaries exempted under the terms of the Notes, such subsidiary will be required to become a party to the security documents within 30 days. In the event of our bankruptcy, liquidation, reorganization or other winding up, the assets of our subsidiaries that are not party to the security documents will be available to pay obligations on the Notes only after all indebtedness and other liabilities (including trade payables) of such subsidiaries have been repaid in full.

On the Closing Date, pursuant to the Purchase Agreement, we delivered to the collateral agent for the Selling Securityholder under the Notes (the “Collateral Agent”) a U.S. security agreement and a U.S. intellectual property security agreement (collectively, the “security documents”), which created a first lien, subject only to certain permitted liens, on substantially all of the tangible and intangible assets, now owned and hereafter created or acquired (except for certain excluded property) by us and the subsidiaries party to the security documents.

The Notes do not bear regular interest. If a Default or an Event of Default (each as defined in “—Events of Default”) occurs, then in each case, to the extent lawful, interest will automatically accrue on the Notes

outstanding as of the date of such Default or Event of Default at a rate per annum equal to 15%, from, and including, the date of such Default or Event of Default, as applicable, to, but excluding, the date such Default is cured and all outstanding Default Interest under this Note has been paid.

On the Closing Date, $35,000,000 of the aggregate purchase price of the Notes and the Registered Notes was deposited into a bank account subject to a “holder directed” account control agreement that does not provide us or our subsidiaries access to the amounts in such account and only permits funds to be released from such account upon the direction of the Collateral Agent (the “Restricted Cash Account”). Not more than once per calendar month (unless the Collateral Agent otherwise agrees), we may request the Collateral Agent to release cash to us from the Restricted Cash Account by delivering a written request duly executed by our chief executive officer or chief financial officer to the Collateral Agent (a “Restricted Cash Request”), including the amount of cash requested to be released and certifying to the satisfaction of the Funding Conditions (as defined below) as of the date of such request, at least two Trading Days prior to the last day of a calendar month in order to make an effective election for such calendar month. Subject to the Funding Conditions (any of which may be waived by the Collateral Agent) continuing to be satisfied through and including the date upon which cash is released from the Restricted Cash Account, the Collateral Agent will cause the amount of cash set forth in the applicable request to be released to us from the Restricted Cash Account on the first business day of the calendar month commencing immediately following the receipt of such Restricted Cash Request (such date a “Restricted Cash Release Date”); provided that, if the Restricted Cash Request is delivered less than two Trading Days prior to the last day of a calendar month, the Restricted Cash Release Date shall be the first calendar day of the second calendar month following the calendar month in which the Restricted Cash Request is delivered.

“Funding Conditions” will be deemed to be satisfied as of any date if (A) the average daily dollar trading volume (as reported on Bloomberg) of our common stock on The Nasdaq Stock Market during the ten Trading Days prior to the date on which a Restricted Cash Request is delivered is not less than $3,500,000; (B) the holder is not in possession of any material non-public information concerning us or any of our subsidiaries, which material non-public information was provided to the holder by or on behalf of us or by or on behalf of any of our employees, agents or advisors; (C) no pending, proposed or intended Fundamental Change or Fundamental Transaction (as defined in the Purchase Agreement) has occurred that has not been abandoned, terminated or consummated; (D) no Default will have occurred or be continuing and no Event of Default will have occurred; (E) our “Adjusted Indebtedness” (as defined below) is less than 25% of our daily market capitalization as calculated on each Trading Day during the 20 consecutive Trading Day period ending on the Trading Day immediately prior to the Restricted Cash Release Date, (F) the Resale Registration Statement (as defined in the Purchase Agreement) registering all shares of our common stock required to be registered pursuant to the Purchase Agreement shall be effective; (G) our common stock (1) shall be listed on The Nasdaq Stock Market and (2) shall not have been suspended by the SEC or Nasdaq from trading on The Nasdaq Stock Market nor shall suspension by the SEC or Nasdaq have been threatened either (x) in writing by the SEC or Nasdaq or (y) by falling below the minimum maintenance requirements of Nasdaq; and (H) we have no reason to believe that the ATM Program or Equity Line of Credit, as applicable, will not be accessible for the foreseeable future, but in any event not less than 12 months from such date. Notwithstanding the foregoing, any waiver of our satisfaction of any Funding Condition will only apply to the Restricted Cash Request and Restricted Cash Release Date to which such Funding Condition so waived relates.

“Adjusted Indebtedness” means (A) our total indebtedness at the time a Restricted Cash Request is delivered, less (B) an amount equal to the difference of (i) the balance of the Restricted Cash Account at the time a Restricted Cash Request is delivered less (ii) the amount of such Restricted Cash Request.

Beginning on November 1, 2023, on the first calendar day of each month through, and including, the Maturity Date (each, a “Partial Redemption Date”), the holders of the Notes will have the right to require us to redeem up to $4,500,000 in aggregate principal amount of the Notes and Registered Notes for a Partial Redemption Payment, payable in cash.

A “Partial Redemption Payment” is an amount equal to 115% of the principal amount of a Note being redeemed.

Partial Redemption Payments will be applied to either the Notes or the Registered Notes at the holders’ option.

Notwithstanding the foregoing, holders of the Notes may, in their sole discretion, defer any Partial Redemption Payments (including any prior Deferred Partial Redemption Payment) (or any portion thereof) one or more times prior to the applicable Partial Redemption Date to any subsequent Partial Redemption Date (in which case such deferred Partial Redemption Payment shall become a “Deferred Partial Redemption Payment”), in which case, on the applicable Partial Redemption Date, we will pay such holders an amount in cash equal to such Partial Redemption Payment (including any Deferred Partial Redemption Payments) to be paid on such date, provided, that the holders may not defer any Partial Redemption Payment or prior Deferred Partial Redemption Payment (or any portion thereof) to the extent that, following such deferral, the total amount of Deferred Partial Redemption Payments outstanding pursuant the Notes and the Registered Notes would exceed $10,350,000.

Any Partial Redemption Payment (or applicable portion thereof) will reduce the principal amount of a Note by the paid amount divided by 1.15.

Upon our mutual agreement with the holders of the Notes, we may agree to increase any single Partial Redemption Payment.

Subject to terms, conditions and certain exceptions set forth in the Notes, beginning on the thirtieth day following the date that the Resale Registration Statement becomes effective, we will have the right to redeem all (but not less than all) of the then outstanding principal amount of the Notes (a “Company Redemption”), on a date to be determined by us (any such date a “Company Redemption Date”), for a cash redemption price equal to the Company Redemption Price (as defined below).

“Company Redemption Price” means, unless prior to the Company Redemption Date, (i) any Default will have occurred and be continuing or Event of Default will have occurred under the Notes that has not been waived by the Required Holders or (ii) any event or circumstance will have occurred and be continuing which, with the giving of notice or passage of time or both, could constitute an Event of Default and has not been waived by the Required Holders (such circumstances constituting collectively a “Company Default Redemption”), means a cash amount equal to the greater of (A) 120% of the outstanding principal amount of the Notes, plus accrued and unpaid interest and (B) the sum of (i) 120% of the product of (a) the applicable conversion rate in effect as of the Trading Day immediately preceding such Company Redemption Date; (b) the total then outstanding principal amount (expressed in thousands) of the Notes; and (c) the highest Daily VWAP per share of our common stock during the period beginning on, and including, the fifth VWAP Trading Day prior to the date that the Company Redemption Notice is delivered and ending on, and including, the VWAP Trading Day immediately preceding such Company Redemption Date and (ii) the accrued and unpaid interest on the Notes. In the event of a Company Default Redemption, Company Redemption Price will mean, a cash amount equal to the greater of (A) the sum of (i) 110% of 115% of the then outstanding principal amount of the Notes and (ii) the accrued and unpaid interest on the Notes and (B) the sum of (i) 120% of the product of (a) the applicable conversion rate in effect as of the Trading Day immediately preceding such Company Redemption Date; (b) the total then outstanding principal amount (expressed in thousands) of the Notes; and (c) the greater of (x) the highest Daily VWAP per share of our common stock occurring during the 30 consecutive VWAP Trading Days ending on, and including, the VWAP Trading Day immediately before the date we deliver notice of our intent to exercise a Company Redemption and (y) the average of the five Daily VWAPs per share of our common stock occurring during the five consecutive VWAP Trading Days ending on, and including, the VWAP Trading Day immediately before the date the applicable Event of Default occurred (or the date on which the Default underlying such Event of Default initially occurred, or the date on which the event or circumstance occurred which, with the giving of notice or passage of time or both, could constitute an Event of Default, if different than the date on which the Event of Default occurred) and (ii) the accrued and unpaid interest on the Notes.

If a Fundamental Change occurs, a holder of Note has the right to require us to repurchase such Note for a cash purchase price equal to the Fundamental Change Repurchase Price, plus accrued interest.

A “Fundamental Change” means any of the following events:

The “Fundamental Change Repurchase Price” means a cash amount equal to the greater of (A) 115% of the outstanding principal amount of the Note to be so repurchased, plus accrued and unpaid interest on such Note and (B) the sum of (i) 115% of the product of (a) the applicable conversion rate in effect as of the Trading Day immediately preceding the effective date of the Fundamental Change; (b) the total then outstanding principal amount (expressed in thousands) of the Notes repurchased; and (c) the average of the five Daily VWAPs per share of our common stock during the five consecutive VWAP Trading Days immediately preceding the effective date of such Fundamental Change and (ii) the accrued and unpaid interest on the Notes repurchased.

On the earlier to occur of (i) the date that no principal amount of the Notes remain outstanding (regardless of whether as a result of redemption, prepayment, payment of the Fundamental Change Repurchase Price, conversion, acceleration upon an Event of Default, or otherwise) or (ii) the Maturity Date, we will pay by wire transfer of immediately available funds the Retirement Fee to the holders of the Notes.

The “Retirement Fee” means an amount equal to the product of (x) $2,187,500 multiplied by (y) a fraction, whose numerator is an amount equal to $35,000,000 less the aggregate principal amount of the Notes converted into shares of our common stock pursuant to the terms of the Notes during the period beginning on, and including, the issue date of the Notes and ending on, and including, the date on which the Notes cease to be outstanding, and whose denominator is $35,000,000.

The initial conversion rate is 349.1925 of the Notes per $1,000 principal amount of the Notes to be converted (which is equivalent to an initial conversion price of approximately $2.8638 per share of common stock).

The conversion rate with respect to the Notes and the conversion price for Notes in effect at any given time are referred to as the “applicable conversion rate” and the “applicable conversion price”, respectively, and will also be subject to adjustment as described below. The applicable conversion price at any given time will be computed by dividing $1,000 by the applicable conversion rate at such time.

If a Forced Conversion Trigger occurs, then we may elect to convert the entire principal amount of each Note into shares of our common stock; provided that (x) no forced conversion will be effected unless the Equity Conditions are satisfied on each VWAP Trading Day from the date of our notice of forced conversion until the corresponding conversion consideration, as provided in the Note, is delivered and (y) if we receive a conversion notice from a holder prior to the date we deliver a notice of forced conversion and any conversion due thereunder remains undelivered by us, the forced conversion may not occur until after such conversion shares are delivered to such holder. The principal amount subject to forced conversion shall be subject to reduction by any principal amount for which a holder has submitted a conversion notice between the time that we provided its notice of forced conversion to the holder and the completion of such forced conversion.

“Forced Conversion Trigger” means (A) the Last Reported Sale Price exceeds 175% of the then applicable conversion price on at least 20 VWAP Trading Days in any 30 consecutive Trading Day period beginning on any VWAP Trading Day after the effective date with respect to the registration statement registering the resale of the Notes and the Underlying Shares (as defined in the Purchase Agreement) pursuant to the Notes and ending on the date upon which we deliver our conversion notice to the holder of the Note and (B) the Equity Conditions are satisfied on the date our conversion notice is delivered by us to the holder.

The applicable conversion rate, as provided in the Notes, is subject to adjustment as a result of the following events:

The conversion consideration, as provided in the Notes, is also subject to adjustment as a result of the following events:

No party may convert all or a portion of a Note or otherwise issue shares of our common stock pursuant to the Note if as a result of the conversion or issuance, a holder and its affiliates would beneficially own in excess of 4.99% of the shares of our common stock. However, upon 61 days’ advance notice to us, a holder may increase the limit of beneficially owned shares of our common stock from 4.99% to any amount up 9.99% of the shares of our common stock. In the event that the issuance of shares of common stock to a holder upon conversion of, or otherwise pursuant to, the Notes results in such holder and its affiliates being deemed to beneficially own, in the aggregate, more than the maximum percentage described in the preceding sentence of the number of outstanding shares of our common stock (as determined under Section 13(d) of the Exchange Act), the number of shares so issued by which the holder’s and its affiliates’ aggregate beneficial ownership exceeds such maximum percentage will be deemed null and void and will be cancelled ab initio, and the holder will not have the power to vote or to transfer such excess shares; provided, however that, in the event of a forced conversion (as described herein under “—Forced Conversion”), if the aggregate number of shares of our common stock that would otherwise be required to be issued to a holder pursuant to such forced conversion would cause such holder to beneficially own shares of our common stock in excess of the maximum percentage described in the preceding sentence, such shares of common stock in excess of such maximum percentage will be held in abeyance for the benefit of the holder until such time or times as its right thereto would not result in the holder and its affiliates exceeding the maximum percentage, at which time or times the holder will be issued such shares (and any such shares declared or made on such initial issuance or on any subsequent issuance held similarly in abeyance) to the same extent as if there had been no such limitation.

The Notes require that we do not and do not permit any of our subsidiaries to:

“Permitted Indebtedness” includes:

The Notes require that we do not, and do not permit any subsidiary to:

If there are dividends or distributions made by us or any subsidiary to any third party pursuant to the distributions covenant, within one business day following the date on which we file an Annual Report on Form 10-K or Quarterly Report on Form 10-Q with the SEC, we will provide the holder with a written notice setting forth the aggregate amount of such dividends or distributions made by us or any subsidiary for the period covered by such Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as applicable.

Notwithstanding the foregoing, we are not permitted to, nor allow any of our subsidiaries to, take the actions described in clause (i) of the first bullet point above in this section, the third bullet point above in this

section or the fourth bullet point above in this section if (A) any Event of Default has occurred and has not been waived by the Required Holders or (B) any event or circumstance has occurred and is continuing which, with the giving of notice or passage of time or both, could constitute an Event of Default with respect to the third, fifth, eighth, ninth, tenth, thirteenth or eighteenth bullet points thereof.

The Notes require that we do not, nor permit our subsidiaries to, voluntarily or involuntarily, transfer, sell, lease, license, lend or in any other manner convey any equitable, beneficial or legal interest in any material portion of our and our subsidiaries’ assets (taken as a whole), other than Permitted Transfers and Permitted Investments.

“Permitted Transfers” include:

less (B) any cash actually received pursuant to any financings or series of related financings during the Liquidity Cash Burn Period, including for the avoidance of doubt, from the sale and issuance of our capital stock, convertible securities, equity-linked securities or indebtedness (including, for the avoidance of doubt, cash actually received in connection with the exercise or settlement of any convertible securities or equity-linked securities).

“Fiscal Half” means each six-month period ending March 31, June 30, September 30 and December 31.

The Notes require that we and our subsidiaries do not enter into, renew, extend, or be a party to, any transaction or series of related transactions (including, without limitation, the purchase, sale, lease, transfer or exchange of property or assets of any kind or the rendering of services of any kind) with any affiliate (other than us or any of our wholly owned subsidiaries), except transactions actually disclosed pursuant to the Purchase Agreement, as in effect on the Closing Date, and any transactions for fair consideration and on terms no less favorable than would be obtainable in a comparable arm’s length transaction with a person that is not an affiliate.

So long as any Note remains outstanding, we are required at all times to have access to an ATM Program, Equity Line of Credit, or similar program approved by the Required Holders, with aggregate available, accessible and unused capacity to generate gross proceeds to us of at least $50,000,000.

For purposes of the quarterly cash spend covenant:

“Available Cash” means, as of any date of determination, (A) the sum of (i) our and our wholly owned subsidiaries’ cash and Cash Equivalents, (ii) any Cash paid by us to a holder pursuant to a Note, Registered Note or Additional Note, if any, during the Quarterly Cash Burn Period, and (iii) any cash paid by us or any of our wholly owned subsidiaries in respect of Covered Milestone Payments during the Quarterly Cash Burn Period, less (B) any cash raised from any financings or series of related financings involving the holder during the Quarterly Cash Burn Period.

We will not consolidate with or merge with or into, or (directly, or indirectly through one or more of our subsidiaries) sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of our and our subsidiaries’ assets, taken as a whole, to another person, other than a holder of a Note or any of its affiliates (a “Business Combination Event”), unless:

At no time will any intellectual property (regardless of the value of such intellectual property) or any other assets with a fair market value in excess of $2,000,000 in the aggregate be held by our foreign subsidiaries, unless the holder shall have been previously granted a perfected first lien security interest in such assets pursuant to security documents, in form and substance reasonably acceptable to the Collateral Agent. Notwithstanding the foregoing, no assets may be held by our foreign subsidiaries in the event that holding such assets would be in violation of the security documents.

We are also required, among other covenants, to:

A “Default” means any event that is (or, after notice, passage of time or both, would be) an Event of Default.

An “Event of Default” means the occurrence of any of the following:

If an Event of Default set forth in the fifteenth or sixteenth bullets under “—Events of Default” occurs with respect to the us (and not solely with respect to one of our significant subsidiaries), then the then outstanding portion of the Maturity Principal Amount of, and all accrued and unpaid interest on, the Notes will immediately become due and payable without any further action or notice by any person.

If an Event of Default (other than an Event of Default set forth in the fifteenth or sixteenth bullets under “—Events of Default”) occurs with respect to us but not solely with respect to one of our subsidiaries and has not been waived, then a holder of a Note may declare such Note to become due and payable on the Business Day immediately following the date of such notice for cash in an amount equal to the Event of Default Acceleration Amount.

If

our common stock is not listed on a U.S. national or regional securities exchange on such Trading Day, then the Last Reported Sale Price will be the last quoted bid price per share of our common stock on such Trading Day in the over-the-counter market as reported by OTC Markets Group Inc. or a similar organization.

“VWAP Trading Day” means a day on which (A) there is no VWAP Market Disruption Event, provided that the holder, by written notice to us, may waive any such VWAP Market Disruption Event; and (B) trading in our common stock generally occurs on the principal U.S. national or regional securities exchange on which our common stock is then listed or, if our common stock is not then listed on a U.S. national or regional securities exchange, on the principal, in terms of volume, Eligible Exchange on which our common stock is then traded. If our common stock is not so listed or traded, then “VWAP Trading Day” means a business day.

The following is a summary of certain material U.S. federal income tax considerations for a U.S. holder (as defined below) generally applicable to (i) the purchase, ownership, disposition, and conversion of the Notes and (ii) the ownership and disposition of the Shares. For purposes of this discussion, the Notes and the Shares are referred to collectively as the “Securities.”

This summary is based upon provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable U.S. Treasury Regulations, administrative rulings, and judicial decisions in effect as of the date hereof, any of which may subsequently be changed or interpreted differently, possibly retroactively, so as to result in U.S. federal income tax consequences different from those discussed below. This summary applies only to Securities that are held as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment) by a U.S. holder that purchased the Securities on original issuance at the “issue price”. This summary is general in nature, and does not address all aspects of U.S. federal income taxation, any estate or gift tax consequences, any alternative minimum tax consequences, the Medicare contribution tax on net investment income, the special tax accounting rules under Section 451(b) of the Code, or any state, local, or non-U.S. tax consequences. In addition, this summary does not deal with all tax consequences that may be relevant to a U.S. holder in light of its personal circumstances or particular situations, such as:

If an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes holds the Securities, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. Partnerships holding the Securities and partners in such partnerships should consult their tax advisors regarding the tax consequences in their particular circumstances.

We have not sought, nor will we seek, a ruling from the Internal Revenue Service (the “IRS”), with respect to the matters discussed below. There can be no assurance that the IRS will not take a different position concerning the tax consequences described herein or that any such position would not be sustained by a court.

As used herein, the term “U.S. holder” means a beneficial owner of the Securities that is, for U.S. federal income tax purposes:

A “non-U.S. holder” is a beneficial owner of the Securities (other than an entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not a U.S. holder. This summary does not apply to non-U.S. holders.

THIS SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. U.S. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE, AND LOCAL AND NON-U.S. INCOME AND NON-INCOME TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, DISPOSITION, AND CONVERSION OF THE NOTES AND THE OWNERSHIP AND DISPOSITION OF THE SHARES IN THEIR PARTICULAR CIRCUMSTANCES.

We intend to treat the Notes (including for purposes of this subsection, the Registered Notes, but excluding the Registered Notes converted into shares of our common stock (the “Initial Conversion Shares”) pursuant to the “Initial Conversion” as that term is used in the Purchase Agreement), the Registered Notes, and the Initial Conversion Shares as an “investment unit” for U.S. federal income tax purposes. The purchase price paid for the investment unit must be allocated among the Notes, the Registered Warrants, and the Initial Conversion Shares, each based on their relative fair market values at the time of the sale, and the portion of such purchase price allocated to the Notes will be the issue price of the Notes. Our allocation of the purchase price among the Notes, the Registered Warrants, and the Initial Conversion Shares is binding on a U.S. holder of the investment unit, unless the U.S. holder explicitly discloses that the U.S. holder’s allocation is different from our allocation. The disclosure generally must be made on a statement attached to the U.S. holder’s timely filed U.S. federal income tax return for the taxable year that includes the U.S. holder’s purchase of the investment unit. U.S. holders may obtain our allocation by contacting us as set forth in the section titled “Where You Can Find More Information.” There can be no assurance that the IRS will respect our allocation or, as applicable, a U.S. holder’s allocation. If the IRS successfully challenges our allocation or, as applicable, a U.S. holder’s allocation, the tax consequences resulting from the new allocation could be different from the tax consequences resulting from our allocation or, as applicable, the U.S. holder’s allocation. U.S. holders should consult their tax advisors regarding the tax treatment of the Notes, the Registered Warrants and the Initial Conversion Shares and the allocation of the purchase price for the Notes, the Registered Warrants and the Initial Conversion Shares.

The Notes were issued with original issue discount (the “OID”) for U.S. federal income tax purposes. The amount of OID is equal to the excess of the Notes’ “stated redemption price at maturity” over its “issue price.” Regardless of a U.S. holder’s method of accounting, the U.S. holder generally will be required to accrue OID on a constant yield to maturity basis, and include such accruals in gross income as ordinary interest income, potentially in advance of the receipt of cash attributable to that income.

The amount of OID allocable to an accrual period generally will equal to the excess of the product of the “adjusted issue price” of the Notes at the beginning of the accrual period and the Notes’ “yield to maturity” (generally determined on the basis of a compounding assumption that reflects the length of the accrual period). The adjusted issue price of the Notes at the beginning of the first accrual period will be the Notes’ issue price. The adjusted issue price of the Notes at the beginning of any subsequent accrual period generally will be the adjusted issue price of the Notes at the beginning of the previous accrual period, increased by the amount of OID allocable to the previous accrual period and decreased by the amount of any payment made on the Notes during the previous accrual period. The yield to maturity of the Notes is the rate that, when used to compute the present value of all payments to be made on the Notes (including for this purpose any scheduled redemption payments on the Notes), produces an amount equal to the issue price of the Notes. The payment schedule of the Notes for OID purposes will include assumptions regarding the holder’s “partial redemptions”, as described in “Description of Notes—Notes—Redemption.” If, contrary to these assumptions, a partial redemption payment is not made, the Notes will be treated as retired and reissued solely for purposes of the OID rules described above.

The rules governing OID are complex. U.S. holders should consult their tax advisors regarding the application of such rules to the Notes, including the amount of OID and the inclusion of OID in gross income.

We may be required to make additional payments on the Notes as described, for example, in the section titled “Description of Notes—Repurchase of the Notes upon a Fundamental Change,” and the amount and timing of certain other payments on the Notes are subject to contingencies. We intend to treat the foregoing

contingencies as not causing the Notes to be subject to the rules governing contingent payment debt instruments. If, contrary to expectations, we make additional payments, although it is not free from doubt, such additional payments should be taxable to a U.S. holder as ordinary income at the time it accrues or is paid in accordance with the U.S. holder’s regular method of tax accounting. U.S. holders should consult their own tax advisors regarding the tax treatment of such additional payments.

Due to a lack of relevant authority regarding these payments, the applicability of the rules governing contingent payment debt instruments to the Notes is uncertain. Our position that the Notes are not subject to the rules governing contingent payment debt instruments is not binding on the IRS. If the IRS successfully challenged this position, and the Notes were treated as a contingent payment debt instruments, a U.S. holder generally would, among other things, be required to accrue interest income at a higher rate than the yield determined under the OID rules, and to treat any gain recognized on the sale or other taxable disposition, or upon the conversion, of the Notes as ordinary income rather than as capital gain. If a U.S. holder disagrees with our position, the U.S. holder generally must explicitly disclose the U.S. holder’s position on a statement attached to the U.S. holder’s timely filed U.S. federal income tax return for the taxable year that includes the U.S. holder’s purchase of the Notes. U.S. holders should consult their tax advisors regarding the applicability of the rules governing contingent payment debt instruments to the Notes and the tax consequences if the Notes were treated as a contingent payment debt instruments.

The remainder of this summary assumes that the Notes are not treated as contingent payment debt instruments.

Except as provided below under the section titled “—Conversion of the Notes,” a U.S. holder generally will recognize capital gain or loss upon the sale, exchange, redemption, repurchase, or other taxable disposition of the Notes (for purposes of this subsection, excluding any scheduled redemption as described under “—Original Issue Discount on the Notes”) equal to the difference, if any, between the sum of the cash plus the fair market value of any other property received upon such disposition and such U.S. holder’s adjusted tax basis in the Notes. A U.S. holder’s adjusted tax basis in the Notes generally will be equal to the amount that the U.S. holder paid for the Notes (taking into account the allocation of purchase price discussion in the section titled “—Characterization of the Notes and Allocation of Purchase Price” above), plus the amount, if any, included in income by the U.S. holder as OID or on an adjustment to the conversion rate of the Notes, as described in the section titled “—Constructive Distributions” below, less the amount of any scheduled redemption payments received on the Notes. Such gain or loss will be capital gain or loss. If, at the time of the sale, exchange, redemption, repurchase, or other taxable disposition of the Notes, the U.S. holder held the Notes for more than one year, any such capital gain or loss would be long-term capital gain or loss. Long-term capital gains recognized by certain non-corporate U.S. holders, including individuals, generally will be subject to a reduced rate of U.S. federal income tax. A U.S. holder’s ability to deduct capital losses may be limited.

If a U.S. holder presents the Notes for conversion, the U.S. holder will receive shares of our common stock in exchange for the principal of the Notes and may receive a retirement fee in cash. The U.S. holder generally will not recognize gain or loss upon the conversion of the Notes, except with respect to the cash received, which may be treated as boot gain in a recapitalization transaction, or alternatively, as gain received in partial redemption of the Notes converted (with the remainder of the Notes treated as converted solely into stock). The tax basis of shares of our common stock received upon a conversion (excluding any Initial Conversion Shares, for which basis will be determined via allocation of purchase price as described in the section titled “—Characterization of the Notes and Allocation of Purchase Price” above) will equal the adjusted tax basis of the Notes that were converted, except that if cash is received in a transaction treated as a recapitalization, the basis will be increased by the amount of gain recognized and decreased by the amount of cash received, and, alternatively, if cash is received in partial redemption, the basis of the Notes will be allocated between the Notes treated as converted and the Notes treated as redeemed. The U.S. holder’s holding period for the shares of common stock will include the period during which the U.S. holder held the Notes.

If we undergo certain of the events described in the section titled “Description of Notes—Conversion Rights—Additional Conversion Rate Adjustments,” the conversion rate and the related conversion consideration may be adjusted such that a U.S. holder would be entitled to convert the Notes into shares, property, or assets

other than our common stock described in such section. Depending on the facts and circumstances at the time of such event, such adjustment may result in a deemed exchange of the Notes, which may be a taxable event for U.S. federal income tax purposes. Furthermore, depending on the circumstances, subsequent to any such event, the U.S. federal income tax consequences of the ownership and conversion of the modified Notes as well as the ownership of the property into which the Notes are convertible may be different from the U.S. federal income tax consequences addressed in this discussion. A U.S. holder should consult its tax advisor regarding the U.S. federal income tax consequences of such an adjustment.

The conversion rate of the Notes will be adjusted in certain circumstances. Under Section 305 of the Code, adjustments (or failures to make adjustments) that have the effect of increasing a U.S. holder’s proportionate interest in our assets or earnings may in some circumstances result in a constructive distribution to a U.S. holder for U.S. federal income tax purposes. Adjustments to the conversion rate made pursuant to a bona fide reasonable adjustment formula that has the effect of preventing the dilution of the interest of U.S. holders, however, generally will not be considered to result in a constructive distribution to a U.S. holder. Certain of the possible conversion rate adjustments provided in the Notes (including, without limitation, adjustments in respect of taxable dividends to holders of our common stock) will not qualify as being pursuant to a bona fide reasonable adjustment formula. If such adjustments are made, depending on the circumstances, including whether we have paid in the past or will pay in the future distributions on our stock or interest on other convertible debt, a U.S. holder may be deemed to have received a distribution even though the U.S. holder has not received any cash or property as a result of such adjustments. In addition, an adjustment to the conversion rate in connection with a make-whole fundamental change may be treated as a constructive distribution. Any constructive distributions will be taxable as a dividend, return of capital, or capital gain as described in the section titled “—Distributions” below.

It is not clear whether a constructive dividend deemed paid to a non-corporate U.S. holder would be eligible for the preferential rates of U.S. federal income tax applicable in respect of certain dividends received. It is also unclear whether corporate U.S. holders would be entitled to claim the dividends-received deduction with respect to any such constructive dividends. Because a constructive dividend deemed received by a U.S. holder would not give rise to any cash from which any applicable withholding could be satisfied, if backup withholding is paid on behalf of a U.S. holder (because such U.S. holder failed to establish an exemption from backup withholding), such backup withholding may be set off against payments of cash and the Shares (or, in certain circumstances, against any payments on the Shares).

We are required under current law to report the amount of any constructive distributions on our website or to the IRS and to U.S. holders not exempt from information reporting. The IRS has proposed regulations addressing the amount and timing of constructive distributions, obligations of withholding agents, and filing and notice obligations of issuers, effective for constructive distributions occurring on or after the date the regulations are adopted in final form. If adopted as proposed, the regulations generally would provide that (i) the amount of a constructive distribution is the excess of the fair market value of the right to acquire the Shares immediately after the conversion rate adjustment over the fair market value of the right to acquire the Shares without the adjustment, (ii) the constructive distribution occurs at the earlier of the date the adjustment occurs under the terms of the Notes and the date of the actual distribution of cash or other property that results in the constructive distribution, (iii) subject to certain limited exceptions, a withholding agent is required to impose any applicable withholding on constructive distributions and, if there is no associated cash payment, may set off its withholding obligations against payments on the Securities or sales proceeds received by, or other funds or assets, of the applicable U.S. holder, and (iv) we will continue to be required to report the amount of any constructive distributions on our website or to the IRS and to all U.S. holders (including those that would otherwise be exempt from information reporting). The final regulations will be effective for constructive distributions occurring on or after the date of adoption, but U.S. holders and withholding agents may rely on them prior to that date under certain circumstances.

U.S. holders should consult their tax advisors regarding the tax consequences of any constructive distributions in their particular circumstances.

Distributions, if any, made on the Shares to a U.S. holder (and constructive distributions, if any, as described above under the section titled “—Constructive Distributions”) generally will be included in the U.S. holder’s income as ordinary dividend income to the extent of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. However, with respect to dividends received by individuals, such dividends generally are taxed at the lower applicable long-term capital gains rates, provided that certain holding period and other requirements are satisfied. Distributions (and constructive distributions) in excess of our current and accumulated earnings and profits will be treated as a return of capital to the extent of a U.S. holder’s tax basis in the Shares or Notes, as applicable, and thereafter as capital gain from the sale or exchange of the Shares or Notes, as applicable. Dividends received by a corporation may be eligible for a dividends-received deduction, subject to applicable limitations.

Upon the sale or other taxable disposition of the Shares, a U.S. holder generally will recognize capital gain or loss equal to the difference between (i) the amount of cash and the fair market value of all other property received upon such disposition and (ii) the U.S. holder’s tax basis in the Shares. Such capital gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period in the Shares is more than one year at the time of the taxable disposition. Long-term capital gains recognized by certain non-corporate U.S. holders (including individuals) generally will be subject to reduced rates of U.S. federal income tax. A U.S. holder’s ability to deduct capital losses may be limited.

Information reporting requirements generally will apply to OID accrued on the Notes, dividends paid on the Shares (and constructive dividends paid on the Notes) and proceeds from a sale or other taxable disposition of the Securities, unless the U.S. holder is an exempt recipient (such as a corporation). Backup withholding (currently at a 24% rate) will apply to those payments if the U.S. holder fails to provide its correct taxpayer identification number, or certification of exempt status, or if the U.S. holder is notified by the IRS that it has failed to report in full payments of interest and dividend income. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a U.S. holder’s U.S. federal income tax liability, provided that the required information is furnished timely to the IRS. U.S. holders should consult their tax advisors regarding their information reporting and backup withholding obligations in their particular circumstances.

THIS SUMMARY IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. U.S. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE, AND LOCAL AND NON-U.S. INCOME AND NON-INCOME TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, DISPOSITION, AND CONVERSION OF THE NOTES AND THE OWNERSHIP AND DISPOSITION OF THE SHARES IN THEIR PARTICULAR CIRCUMSTANCES, INCLUDING ANY INFORMATION REPORTING REQUIREMENTS AND THE IMPACT OF ANY POTENTIAL CHANGE IN LAW.

On October 13, 2023, we issued and sold to the Selling Securityholder pursuant to the Purchase Agreement in a registered offering the Registered Notes and Registered Warrants and in a concurrent private placement $35.0 million aggregate principal amount of Notes initially convertible by the Selling Securityholder into 12,221,738 Shares. The Purchase Agreement provided the Selling Securityholder with registration rights with respect to the Notes and Shares. The Selling Securityholder, which term includes any additional selling stockholder listed in a prospectus supplement, and their donees, pledgees, assignees, transferees, distributees or other successors in interest selling securities received after the date of this prospectus from the Selling Securityholder as a non-sale transfer, may from time to time offer and sell the Notes and the Shares pursuant to this prospectus or any applicable prospectus supplement.

The following table sets forth certain information as of the date of this prospectus, concerning the principal amount of Notes beneficially owned and the Shares that may be offered from time to time under this prospectus by the Selling Securityholder named in the table. We prepared this table based on the information supplied to us by the Selling Securityholder named in the table and we have not sought to verify such information. This table only reflects information the Selling Securityholder provided us. Information concerning the Selling Securityholder may change from time to time and any changed information will be set forth in supplements to this prospectus if and when necessary.

The number of Shares issuable upon conversion of the Notes shown in the table below assumes conversion of the full amount of Notes held by the Selling Securityholder at an initial conversion rate of 349.1925 shares per $1,000 principal amount of notes. This conversion price is subject to adjustment in certain events. Accordingly, the number of conversion shares may increase or decrease from time to time. The percentages of common stock beneficially owned and being offered are based on 37,722,920 shares of our common stock outstanding as of October 23, 2023. Because the Selling Securityholder may offer all or some portion of the Notes or the Shares pursuant to this prospectus, we have assumed for purposes of the table below that the Selling Securityholder will sell all of the Notes and all of the shares of common stock offered pursuant to this prospectus. In addition, the Selling Securityholder identified below may have sold, transferred or otherwise disposed of all or a portion of its Notes in transactions exempt from the registration requirements of the Securities Act since the date on which they provided the information to us regarding their holdings.

Based upon information provided by the Selling Securityholder, none of the Selling Securityholder or any of its affiliates, officers, directors or principal equity holders has held any position or office or has had any material relationship with us within the past three years.

In addition, except as indicated in the table below, the selling securityholders have represented to us that they are not, nor are they affiliated with, a registered broker-dealer.

Under the terms of the Notes, the Selling Securityholder may not receive any shares of our common stock otherwise deliverable upon conversion of the Notes to the extent, but only to the extent, that such receipt would cause the Selling Securityholder to become, directly or indirectly, the beneficial owner of more than 4.99% of the shares of our common stock outstanding at such time. The number of shares of common stock in the fifth column do not reflect these limitations, but the percentage set forth in the seventh column does give effect to such limitations. The Selling Stockholders may sell all, some or none of their shares in this offering. In addition, we do not know how long the Selling Securityholder will hold the Notes or any Shares upon conversion of the Notes before selling them, and we currently have no agreements, arrangements or understandings with the Selling Securityholder regarding the sale or other disposition of any Notes or Shares. See the section titled “Plan of Distribution.”

We are registering the resale by the Selling Securityholder or its permitted transferees from time to time of (i) up to $35,000,000 aggregate principal amount of Notes and (ii) up to 12,221,738 Shares. We will not receive any of the proceeds from the sale of the securities by the Selling Securityholder. The aggregate proceeds to the Selling Securityholder will be the purchase price of the securities less any discounts and commissions borne by the Selling Securityholder. We are required to pay all fees and expenses incident to the registration of the securities to be offered and sold pursuant to this prospectus. The Selling Securityholder will bear all commissions and discounts, if any, attributable to its sale of securities.

The shares of common stock beneficially owned by the Selling Securityholder covered by this prospectus may be offered and sold from time to time by the Selling Securityholder. The term “Selling Securityholder” includes any additional selling stockholder listed in a prospectus supplement, and their donees, pledgees, assignees, transferees, distributees or other successors in interest selling securities received after the date of this prospectus from the Selling Securityholder as a non-sale transfer, may from time to time offer and sell the Notes and the Shares pursuant to this prospectus or any applicable prospectus supplement. The Selling Securityholder will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. The Selling Securityholder may sell its securities by one or more of, or a combination of, the following methods:

In addition, any securities that qualify for sale pursuant to Rule 144 or another exemption from registration under the Securities Act or other such exemption may be sold under Rule 144 or such other exemption rather than pursuant to this prospectus.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. In connection with distributions of the securities or otherwise, the Selling Securityholder may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of the securities in the course of hedging the positions they assume with the Selling Securityholder. The Selling Securityholder may also sell the securities short and redeliver the securities to close out such short positions. The Selling Securityholder may also enter into option or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). The Selling Securityholder may also pledge securities to a broker-dealer or other financial institution, and, upon a default, such broker-dealer or other financial institution, may effect sales of the pledged securities pursuant to this prospectus (as supplemented or amended to reflect such transaction).

In effecting sales, broker-dealers or agents engaged by the Selling Securityholder may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the Selling Securityholder in amounts to be negotiated immediately prior to the sale.

In order to comply with the securities laws of certain states, if applicable, the securities must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

We also have agreed to indemnify the Selling Securityholder and certain other persons against certain liabilities in connection with the offering of Notes and Shares offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. The Selling Securityholder has agreed to indemnify us against liabilities under the Securities Act that may arise from certain written information furnished to us by the Selling Securityholder specifically for use in this prospectus or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons, we have been advised that in the opinion of the SEC this indemnification is against public policy as expressed in the Securities Act and is therefore, unenforceable.

We have advised the Selling Securityholder that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of securities in the market and to the activities of the Selling Securityholder and its affiliates. In addition, we will make copies of this prospectus available to the Selling Securityholder for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Securityholder may indemnify any broker-dealer that participates in transactions involving the sale of the securities against certain liabilities, including liabilities arising under the Securities Act.

At the time a particular offer of securities is made, if required, a prospectus supplement will be distributed that will set forth the number of securities being offered and the terms of the offering, including the name of any underwriter, dealer or agent, the purchase price paid by any underwriter, any discount, commission and other item constituting compensation, any discount, commission or concession allowed or reallowed or paid to any dealer, and the proposed selling price to the public.

The validity of the Shares and the Notes have been passed upon by Morris, Nichols, Arsht & Tunnell LLP, Wilmington, Delaware.
