[424B4] Bionano Genomics, Inc. Prospectus Filed Pursuant to Rule 424(b)(4)

Rhea-AI Filing Summary

Bionano Genomics, Inc. (BNGO) is offering 4,925,000 shares of common stock, 75,000 pre-funded warrants and 10,000,000 warrants (Series E and F) that together could result in 10,075,000 shares if exercised. The prospectus discloses expected closing and delivery around September 17, 2025 and a Nasdaq closing stock price of $2.77 per share on September 15, 2025. Estimated net proceeds after placement agent fees and offering expenses are approximately $9.0 million. Placement agent compensation totals 6.0% cash fee plus 0.5% management fee and specified expense reimbursements. The company warns of a limited trading market and liquidity for the Pre-Funded Warrants and Warrants, and states it needs significant additional financing and must manage costs to continue as a going concern within 12 months of its Form 10-Q for the quarter ended June 30, 2025. The prospectus lists outstanding potential dilution: 191,532 option shares, 2,081,089 warrant shares, 633,704 convertible-note shares and various plan reserves.

Positive

• Common stock listed on Nasdaq under symbol BNGO, providing an established trading venue for the common shares
• Estimated net proceeds ~ $9.0 million after placement agent fees and offering expenses to support operations
• Placement agent terms disclosed, including specific fees and reimbursable expense caps, increasing transaction transparency

Negative

• Going-concern risk: company states it requires significant additional financing and cost management to continue within 12 months of the June 30, 2025 Form 10-Q
• Limited liquidity for the Pre-Funded Warrants and Warrants because no market listing is expected for those instruments
• Potential dilution: material outstanding convertible instruments and plan reserves (e.g., 2,081,088.57 warrant shares, 633,703.70 convertible-note shares, and other option and reserve amounts) could dilute shareholders

Insights

Financial Analyst

TL;DR Net proceeds are modest versus stated need for significant additional financing; going-concern risk is material.

The offering is structured to raise roughly $9.0 million after fees, while the filing explicitly states the company must obtain significant additional financing and manage costs to continue as a going concern within 12 months of its June 30, 2025 Form 10-Q. Placement agent fees of 6.0% plus a 0.5% management fee and other reimbursables reduce net proceeds. Substantial potential dilution exists from outstanding options, warrants and convertible notes totaling millions of shares that could pressure existing shareholders. The lack of a trading market for the Pre-Funded Warrants and Warrants limits liquidity for those instruments. Overall, the financing appears incremental and may be insufficient to resolve near-term liquidity risks.

Corporate Governance Expert

TL;DR Charter and bylaw provisions make hostile takeovers harder and centralize control with the board.

The prospectus discloses governance measures including staggered board classes, limits on stockholder actions by written consent, supermajority removal thresholds, exclusive forum provisions and authorization of undesignated preferred stock. These provisions can impede unsolicited acquisition attempts and make board replacement or management changes more difficult, which protects continuity but can entrench existing management. For investors, these measures affect the corporate control landscape and may reduce the likelihood of change-in-control transactions.

PROSPECTUS

4,925,000 Shares of Common Stock

75,000 Pre-Funded Warrants to Purchase up to 75,000 Shares of Common Stock

5,000,000 Series E Warrants to Purchase up to 5,000,000 Shares of Common Stock

5,000,000 Series F Warrants to Purchase up to 5,000,000 Shares of Common Stock

10,075,000 Shares of Common Stock Issuable Upon Exercise of the

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

We are offering 4,925,000 shares of common stock, par value $0.0001 per share (“common stock”), together with Series E warrants to purchase 4,925,000 shares of common stock (the “Series E Warrants”) and Series F warrants to purchase up to 4,925,000 shares of common stock (the “Series F Warrants”, and together with the Series E Warrants, the “Warrants”) at a combined public offering price of $2.00 per share and accompanying Warrants pursuant to this prospectus. The shares of common stock and Warrants will be separately issued, but must be purchased together in this offering. Each share of common stock is being sold together with one Series E Warrant to purchase one share of common stock and one Series F Warrant to purchase one share of common stock. Each Warrant will have an exercise price of $2.00 per share (representing 100% of the combined price at which a share of common stock and accompanying Warrants are sold to the public in this offering) and will be exercisable upon issuance (the “Initial Exercise Date”). The Series E Warrants will expire on the five-year anniversary of the Initial Exercise Date. The Series F Warrants will expire on the 18-month anniversary of the Initial Exercise Date.

We are also offering 75,000 pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to an aggregate of up to 75,000 shares of common stock to those purchasers whose purchase of shares of common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock following the consummation of this offering in lieu of the shares of our common stock that would result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%). Each Pre-Funded Warrant will be exercisable for one share of common stock at an exercise price of $0.0001 per share. Each Pre-Funded Warrant is being issued together with the same Warrants described above being issued with each share of common stock. The combined public offering price for each such Pre-Funded Warrant, together with the accompanying Warrants, is $1.9999, which is equal to the combined public offering price, less the $0.0001 per share exercise price of each such Pre-Funded Warrant. Each Pre-Funded Warrant will be exercisable upon issuance and will expire when exercised in full. The Pre-Funded Warrants and accompanying Warrants are immediately separable and will be issued separately in this offering, but must be purchased together in this offering. For each Pre-Funded Warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. This offering also relates to the shares of common stock issuable upon the exercise of the Warrants and the Pre-Funded Warrants.

This offering will terminate on October 11, 2025, unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The combined public offering price per share (or Pre-Funded Warrant) and accompanying Warrants will be fixed for the duration of this offering.

We have engaged H.C. Wainwright & Co., LLC (the “placement agent”) to act as our exclusive placement agent in connection with this offering. The placement agent has agreed to use its reasonable best efforts to arrange for the sale of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities we are offering, and the placement agent is not required to arrange the purchase or sale of any specific number or dollar amount of securities. We have agreed to pay to the placement agent the placement agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus. There is no arrangement for funds to be received in escrow, trust or similar arrangement. There is no minimum offering requirement. We will bear all costs associated with the offering. See “Plan of Distribution” on page 18 of this prospectus for more information regarding these arrangements.

Our common stock is currently listed on the Nasdaq Capital Market under the symbol “BNGO.” On September 15, 2025, the closing price of our common stock on the Nasdaq Capital Market was $2.77 per share. There is no established public trading market for the Pre-Funded Warrants or Warrants that are part of this offering, and we do not expect a market to develop. We do not intend to apply for listing of the Pre-Funded Warrants or Warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the Pre-Funded Warrants and Warrants will be limited.

You should read this prospectus, together with additional information described under the headings “Information Incorporated by Reference” and “Where You Can Find More Information,” carefully before you invest in any of our securities.

PROSPECTUS SUMMARY

This summary highlights information about our company, this offering and information contained in greater detail in other parts of this prospectus or incorporated by reference into this prospectus from our filings with the SEC listed in the section titled “Information Incorporated by Reference.” Because it is only a summary, it does not contain all of the information that you should consider before purchasing our securities in this offering, and it is qualified in its entirety by, and should be read in conjunction with, the more detailed information appearing elsewhere or incorporated by reference into this prospectus. You should read the entire prospectus, the registration statement of which this prospectus is a part, and the information incorporated by reference into this prospectus in their entirety, including the “Risk Factors” and our financial statements and the related notes incorporated by reference into this prospectus, before purchasing our securities in this offering. Except as otherwise indicated herein or as the context otherwise requires, all references in this prospectus to “Bionano,” “the Company,” “we,” “us,” “our” and similar references refer to Bionano Genomics, Inc. and its subsidiaries or, as the context may require, Bionano Genomics, Inc. only. “Bionano Laboratories,” “BioDiscovery” and “Purigen” refer to our wholly owned subsidiaries, Lineagen, Inc. (doing business as Bionano Laboratories), BioDiscovery, LLC and Purigen Biosystems, Inc., respectively.

Corporate Overview

We are a provider of genome analysis solutions that can enable researchers and clinicians to reveal answers to challenging questions in biology and medicine. Our mission is to transform the way the world sees the genome through optical genome mapping (“OGM”) solutions, diagnostic services and software. We offer OGM solutions for applications across basic, translational and clinical research, and for other applications including bioprocessing. We offer a platform-agnostic software solution, which integrates next-generation sequencing, microarray and OGM data designed to provide analysis, visualization, interpretation and reporting of copy number variants, single-nucleotide variants and absence of heterozygosity across the genome in one consolidated view. The Company also offers nucleic acid extraction and purification solutions using proprietary isotachophoresis ITP technology. Through our Bionano Laboratories business, we also provide OGM-based diagnostic testing services.

We market and sell OGM systems, including the Saphyr® system and the Stratys™ system, which deliver OGM data to enable ultra-sensitive and ultra-specific detection of all classes of structural variation (“SV”). These systems are used to identify structural changes in chromosomes, the study of which is known as cytogenetics, and to accelerate the search for answers in genetic disease and cancer applications as well as in applications for cell and gene therapy. The systems are comprised of an instrument, chip consumables, reagents and software containing a suite of data analysis and visualization tools. OGM has been shown to outperform the current gold standard cytogenetic methods including karyotyping, fluorescence in-situ hybridization (“FISH”), Southern blot and chromosomal microarray (“CMA”), for the detection of SVs. OGM has also been shown to identify structural changes in chromosomes that cannot be identified using current commercially available gene sequencing solutions.

We market and sell the Ionic® Purification system, which is able to deliver high quality DNA in a more natural, native form and with fewer contaminants when compared to other isolation and purification solutions. The Ionic® Purification system is used to extract, purify, and concentrate DNA or RNA from a variety of sample types, and is comprised of an instrument, consumables, and reagents.

We market and sell the VIA™ software which delivers genomic data interpretation solutions tailored for research use in cytogenomics and molecular pathology labs in genetic disease and cancer research markets, with an emphasis on SV. This industry leading, platform agnostic software solution is designed to provide analysis, visualization, interpretation and reporting of SVs, single-nucleotide variants and absence of heterozygosity across the genome in one consolidated view. Our software currently enables analysis of OGM, next-generation sequencing (“NGS”) and microarray data. We believe the integration of OGM with data types common in the industry, such as Variant Call Format (“VCF”), and Binary Alignment Map (“BAM”), into the VIA software should accelerate and broaden our position in digital cytogenetics and comprehensive genome analysis by enabling us to simplify the assessment of clinically relevant variants in cytogenomics applications, potentially reducing interpretation time per sample and expanding our reach into the discovery and translational research markets through the combination of OGM and NGS.

Our Bionano Laboratories business has developed and provides several OGM-based laboratory developed tests (“LDTs”) for facioscapulohumeral muscular dystrophy type 1 (“FSHD1”), which is a progressive disorder that primarily affects the muscles of the face, shoulder blades (scapula), upper arms, and lower legs, for detecting SVs in individuals with hematologic malignancies, and for detecting SVs in pre- and post-natal samples, through its

1

TABLE OF CONTENTS

OGM-Dx™ testing services. During 2024, Bionano Laboratories phased out the offering of certain testing services for individuals demonstrating clinical presentations consistent with neurodevelopmental disorders (“NDDs”), including autism spectrum disorders (“ASDs”) and other disorders of childhood development.

Bionano Laboratories also provides laboratory services to clinicians, scientists, pharmaceutical companies, and others who are seeking to incorporate OGM into their genomics research without the need to bring one of our OGM systems in house. Laboratory services for OGM are performed in our laboratory facilities in San Diego, California and at partner laboratories in the United States and Europe, and serve as solutions for researchers and clinicians who would like to use OGM for various applications in genomics but have yet to acquire an OGM system.

We believe we have transformed our business from an instrument company to a provider of a full suite of genomic solutions. We expanded into molecular genetic clinical testing services through our August 2020 acquisition of Lineagen. We furthered our transformation through the expansion into software solutions, made possible by our October 2021 acquisition of BioDiscovery and continued with our November 2022 acquisition of Purigen bringing their leading nucleic acid isolation and purification technology to Bionano. We believe that these acquisitions, along with internal investments in research and development and the build out of our commercial teams, have positioned us well to provide solutions to our customers that we believe will make OGM the standard cytogenetic technique for structural variant analysis.

Implications of Being a Smaller Reporting Company

We are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company until the last day of any fiscal year for so long as either (1) the market value of our shares of common stock held by non-affiliates does not equal or exceed $250.0 million as of the prior June 30th, or (2) our annual revenues did not equal or exceed $100.0 million during such completed fiscal year and the market value of our shares of common stock held by non-affiliates did not equal or exceed $700.0 million as of the prior June 30th. To the extent we take advantage of any reduced disclosure obligations, it may make comparison of our financial statements with other public companies difficult or impossible.

Corporate Information

We were formed in January 2003 as BioNanomatrix LLC, a Delaware limited liability company. In August 2007, we became BioNanomatrix Inc., a Delaware corporation. In October 2011, we changed our name to BioNano Genomics, Inc., and in July 2018, we changed our name to Bionano Genomics, Inc.

Our principal executive offices are located at 9540 Towne Centre Drive, Suite 100, San Diego, California 92121, and our telephone number is (858) 888-7600. Our website address is www.bionanogenomics.com, and we regularly post copies of our press releases as well as additional information about us on our website.

THE OFFERING

Common Stock to be Offered

4,925,000 shares at a combined public offering price of $2.00 per share of common stock and accompanying Warrants.

Pre-Funded Warrants to be Offered

We are also offering to certain purchasers whose purchase of shares of common stock in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if such purchasers so choose, Pre-Funded Warrants to purchase shares of common stock, in lieu of shares of common stock that would otherwise result in any such purchaser’s beneficial ownership exceeding 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. Each Pre-Funded Warrant will be exercisable for one share of our common stock. The purchase price of each Pre-Funded Warrant and accompanying Warrants will equal the price at which the share of common stock and accompanying Warrants are being sold to the public in this offering, minus $0.0001, and the exercise price of each Pre-Funded Warrant will be $0.0001 per share. The Pre-Funded Warrants will be exercisable immediately and may be exercised at any time until all of the Pre-Funded Warrants are exercised in full. Purchasers of Pre-Funded Warrants will also receive accompanying Warrants as if such purchasers were buying shares of our common stock in this offering. This prospectus also relates to the offer and sale of the shares of common stock issuable upon exercise of the Pre-Funded Warrants sold in this offering.

For each Pre-Funded Warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. Because we will issue accompanying Warrants for each share of our common stock and for each Pre-Funded Warrant to purchase one share of our common stock sold in this offering, the number of Warrants sold in this offering will not change as a result of a change in the mix of the shares of our common stock and Pre-Funded Warrants sold. See “Description of Securities – Pre-Funded Warrants” for additional information.

Warrants to be Offered

Each share of our common stock and each Pre-Funded Warrant to purchase one share of our common stock is being sold together with one Series E Warrant to purchase one share of our common stock and one Series F Warrant to purchase one share of our common stock.

Each Warrant will have an exercise price of $2.00 per share (representing 100% of the combined price at which a share of common stock and accompanying Warrants

3

TABLE OF CONTENTS

are sold to the public in this offering) and will be exercisable upon issuance. The Series E Warrants will expire on the five-year anniversary of the Initial Exercise Date. The Series F Warrants will expire on the 18-month anniversary of the Initial Exercise Date.

The shares of common stock and the accompanying Warrants and the Pre-Funded Warrants and the accompanying Warrants, as the case may be, can only be purchased together in this offering but will be issued separately and will be immediately separable upon issuance. This prospectus also relates to the offer and sale of the shares of common stock issuable upon exercise of the Warrants. See “Description of Securities — Warrants” for additional information.

Common Stock Outstanding Immediately Prior to this Offering⁽¹⁾

4,755,265 shares of common stock.

Common Stock to be Outstanding Immediately After this Offering⁽¹⁾

9,755,265 shares of common stock (assuming full exercise of the Pre-Funded Warrants and assuming no exercise of the Warrants offered hereby).

Use of Proceeds

We estimate that the net proceeds from this offering will be approximately $9.0 million, based on a combined public offering price of $2.00 per share of common stock and accompanying Warrants, after deducting the placement agent fees and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of the Warrants.

We currently intend to use the net proceeds from the offering for working capital and general corporate purposes. See “Use of Proceeds” for additional information.

Risk Factors

An investment in our securities involves a high degree of risk. See “Risk Factors” beginning on page 6 of this prospectus and the other information included and incorporated by reference in this prospectus for a discussion of the risk factors you should carefully consider before deciding to invest in our securities.

National Securities Exchange Listing

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

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

TABLE OF CONTENTS

RISK FACTORS

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

Risks Related to this Offering

We have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

Our management will have broad discretion in the application of the net proceeds, including for any of the purposes described in the section of this prospectus titled “Use of Proceeds”. You will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the net proceeds are being used appropriately. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, cause the price of our securities to decline and delay the commercialization of our products and technologies. Pending the application of these funds, we may invest the net proceeds from this offering in a manner that does not produce income or that loses value.

There is no public market for the Warrants or Pre-Funded Warrants being offered by us in this offering.

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

The Warrants and Pre-Funded Warrants are speculative in nature.

The Warrants and Pre-Funded Warrants offered hereby do not confer any rights of share of common stock ownership on their holders, such as voting rights, but rather merely represent the right to acquire shares of common stock at a fixed price. Specifically, commencing on the date of issuance, holders of the Warrants may acquire the shares of common stock issuable upon exercise of such warrants at an exercise price of $2.00 per share of common stock, and holders of the Pre-Funded Warrants may acquire the shares of common stock issuable upon exercise of such warrants at an exercise price of $0.0001 per share of common stock. Moreover, following this offering, the market value of the Warrants and Pre-Funded Warrants is uncertain and there can be no assurance that the market value of the Warrants or Pre-Funded Warrants will equal or exceed their respective public offering prices. There can be no assurance that the market price of the shares of common stock will ever equal or exceed the exercise price of the Warrants or Pre-Funded Warrants, and consequently, whether it will ever be profitable for holders of Warrants to exercise the Warrants or for holders of the Pre-Funded Warrants to exercise the Pre-Funded Warrants.

Holders of the Pre-Funded Warrants and the Warrants offered hereby will have no rights as common stockholders with respect to the shares our common stock underlying the warrants until such holders exercise their warrants and acquire our common stock, except as otherwise provided in the Pre-Funded Warrants and the Warrants.

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

Purchasers who purchase our securities in this offering pursuant to a securities purchase agreement may have rights not available to purchasers who purchase without the benefit of a securities purchase agreement.

In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers who enter into a securities purchase agreement will also be able to bring claims of breach of contract

TABLE OF CONTENTS

against us. The ability to pursue a claim for breach of contract provides those investors with the means to enforce the covenants uniquely available to them under the securities purchase agreement including, but not limited to: (i) timely delivery of securities; (ii) agreement to not enter into variable rate financings for a period of time after closing, subject to certain exceptions; (iii) agreement to not enter into any financings for a period of time after closing, subject to certain exceptions; and (iv) indemnification for breach of contract.

This is a best efforts offering, with no minimum amount of securities is required to be sold, and we may not raise the amount of capital we believe is required for our business plans, including our near-term business plans.

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

If we are not able to comply with the applicable continued listing requirements or standards of the Nasdaq Capital Market, Nasdaq could delist our common stock.

Our ability to publicly or privately sell equity securities and the liquidity of our common stock could be adversely affected if we are delisted from the Nasdaq Capital Market or if we are unable to transfer our listing to another stock market. In order to maintain this listing, we must satisfy minimum financial and other continued listing requirements and standards, including a requirement to maintain a minimum bid price of our common stock of $1.00 per share pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”).

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

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

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

TABLE OF CONTENTS

We do not currently intend to pay dividends on our common stock, and any return to investors is expected to come, if at all, only from potential increases in the price of our common stock.

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

TABLE OF CONTENTS

USE OF PROCEEDS

We estimate that the net proceeds from the offering will be approximately $9.0 million, based on a combined public offering price per share of common stock and accompanying Warrants of $2.00, after deducting the placement agent fees and estimated offering expenses payable by us, assuming full exercise of the Pre-Funded Warrants offered hereunder but no exercise of any of the Warrants offered hereunder. However, because this is a best efforts offering and there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, the placement agent fees and net proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus.

These estimates exclude the proceeds, if any, from the exercise of the Warrants issued in this offering. If all of the Warrants issued in this offering were to be exercised in cash at an exercise price of $2.00 per share of common stock, we would receive additional proceeds of approximately $20.0 million. We cannot predict when or if these Warrants will be exercised. It is possible that these Warrants may expire and may never be exercised. Additionally, the Warrants contain a cashless exercise provision that permit exercise of Warrants on a cashless basis at any time where there is no effective registration statement under the Securities Act covering the issuance of the underlying shares.

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

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

DIVIDEND POLICY

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

TABLE OF CONTENTS

DESCRIPTION OF CAPITAL STOCK

The following summary describes our securities registered under Section 12 of the Exchange Act, certain provisions of our amended and restated certificate of incorporation, as amended (“Restated Certificate”), our amended and restated and bylaws, as amended (“Bylaws”), and certain provisions of the General Corporation Law of the State of Delaware (“DGCL”). Because it is only a summary, the following description of our capital stock is not complete and does not contain all of the information that may be important to you. The following summary is subject to and qualified in its entirety by reference to our Restated Certificate and Bylaws, copies of which are filed as exhibits to our Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, filed with the SEC on August 14, 2025, and the forms of securities, copies of which are filed as exhibits to the registration statement of which this prospectus forms a part, which are incorporated by reference herein.

General

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

As of September 9, 2025, there were 4,755,265 shares of common stock outstanding. Our authorized but unissued shares of common stock and preferred stock are available for issuance without further action by our stockholders, unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded in the future.

Common Stock

Voting Rights

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

Economic Rights

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

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

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

No Preemptive or Similar Rights

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.

Preferred Stock

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,

11

TABLE OF CONTENTS

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.

Anti-Takeover Provisions

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

Section 203 of the Delaware General Corporation Law

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

• before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

• upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

• on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholder, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

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

• any merger or consolidation involving the corporation and the interested stockholder;

• any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;

• subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

• any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or

• the receipt by the interested stockholder of the benefit of any loss, advances, guarantees, pledges or other financial benefits by or through the corporation.

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

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

12

TABLE OF CONTENTS

Certificate of Incorporation and Bylaws

Among other things, the Restated Certificate and the Bylaws:

• do not provide stockholders with cumulative voting rights such that stockholders holding a plurality of the voting power of our shares of common stock would be able to elect all of our directors;

• provide for stockholder actions to be taken at a duly called meeting of stockholders and not by written consent;

• provide that a special meeting of stockholders may only be called by a majority of our board of directors, the chair of our board of directors or our chief executive officer;

• establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our board of directors;

• divide our board of directors into three classes with staggered three-year terms;

• provide that the authorized number of directors may be changed only by resolution adopted by a majority of the authorized number of directors constituting the board of directors;

• provide that the board of directors or any individual director may only be removed with cause and the affirmative vote of the holders of at least 66 2/3% of the voting power of all of our then outstanding shares of common stock; and

• provide that all vacancies, including newly created directorships, may, except as otherwise required by law or subject to the rights of holders of preferred stock as designated from time to time, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum.

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

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

Choice of Forum

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

Transfer Agent and Registrar

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

Listing on the Nasdaq Capital Market

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

TABLE OF CONTENTS

DESCRIPTION OF SECURITIES WE ARE OFFERING

We are offering 4,925,000 shares of our common stock, Series E Warrants to purchase up to 5,000,000 shares of common stock and Series F Warrants to purchase up to 5,000,000 shares of common stock. We are also offering Pre-Funded Warrants to purchase up to 75,000 shares of common stock to those purchasers whose purchase of shares of common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding shares of common stock following the consummation of this offering in lieu of the shares of common stock that would result in such excess ownership. Each Pre-Funded Warrant will be exercisable for one share of common stock. Each Pre-Funded Warrant is being issued together with the same Warrants described above being issued with each share of common stock. For each Pre-Funded Warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. The shares of common stock or Pre-Funded Warrants, as the case may be, and the accompanying Warrants, can only be purchased together in this offering, but the shares of common stock and Pre-Funded Warrants and accompanying Warrants are immediately separable and will be issued separately in this offering. We are also registering the shares of common stock issuable from time to time upon exercise of the Pre-Funded Warrants and Warrants offered hereby.

Common Stock

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

Warrants

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

Duration and Exercise Price

Each Warrant offered hereby has an exercise price equal to $2.00 (representing 100% of the combined price at which a share of common stock and accompanying Warrants are sold to the public in this offering). The Warrants will be immediately exercisable upon issuance (the “Initial Exercise Date”). The Series E Warrants will expire on the five-year anniversary of the Initial Exercise Date. The Series F Warrants will expire on the 18-month anniversary of the Initial Exercise Date. The exercise price and number of shares of common stock issuable upon exercise of the Warrants is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. The Warrants will be issued separately from the common stock or Pre-Funded Warrants, respectively, and may be transferred separately immediately thereafter. The Warrants will be issued in certificated form only.

Exercisability

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

Cashless Exercise

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

TABLE OF CONTENTS

Fundamental Transactions

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

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

Transferability

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

Fractional Shares

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

Trading Market

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

Right as a Stockholder

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

Waivers and Amendments.

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

Pre-Funded Warrants

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

TABLE OF CONTENTS

Duration and Exercise Price

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

Exercisability

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

Cashless Exercise

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

Fractional Shares

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

Transferability

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

Trading Market

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

Right as a Shareholder

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

Fundamental Transaction

In the event of a fundamental transaction, as described in the Pre-Funded Warrants and generally including any reorganization, recapitalization or reclassification of our shares of common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another

TABLE OF CONTENTS

person, the acquisition of 50% or more of our outstanding securities, or any person or group becoming the beneficial owner of 50% or more of the voting power represented by our outstanding shares of securities, the holders of the Pre-Funded Warrants will be entitled to receive upon exercise of the Pre-Funded Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Pre-Funded Warrants immediately prior to such fundamental transaction.

PLAN OF DISTRIBUTION

Pursuant to an engagement agreement, dated July 9, 2025 (the “Engagement Agreement”), we have engaged H.C. Wainwright & Co., LLC to act as our exclusive placement agent to solicit offers to purchase the securities offered by this prospectus on a reasonable best efforts basis. The Engagement Agreement does not give rise to any commitment by the placement agent to purchase any of our securities, and the placement agent will have no authority to bind us by virtue of the Engagement Agreement. The placement agent is not purchasing or selling any securities, nor is it required to arrange for the purchase and sale of any specific number or dollar amount of securities, other than to use its “reasonable best efforts” to arrange for the sale of the securities by us. Therefore, we may not sell the entire amount of securities being offered.

The terms of this offering are subject to market conditions and negotiations between us, the placement agent and prospective investors. The placement agent will have no authority to bind us by virtue of the engagement letter. This is a best efforts offering and there is no minimum amount of proceeds that is a condition to closing of this offering. Investors purchasing securities offered hereby will have the option to execute a securities purchase agreement with us. In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers which enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The placement agent may engage one or more sub-agents or selected dealers in connection with the offering. The ability to pursue a claim for breach of contract is material to larger purchasers in this offering as a means to enforce the following covenants uniquely available to them under the securities purchase agreement: (i) a covenant to not enter into variable rate financings for a period of one year following the closing of the offering, subject to certain exceptions; and (ii) a covenant to not enter into any equity financings for 30 days from closing of the offering, subject to certain exceptions.

The nature of the representations, warranties and covenants in the securities purchase agreements will include:

• standard and customary issuer representations and warranties on matters such as due organization, qualification, authorization, no conflict, no governmental filings required, currentness and accuracy of SEC filings, absence of litigation, labor or other compliance issues, environmental, intellectual property and title matters and compliance with various laws such as the Foreign Corrupt Practices Act; and

• covenants regarding matters such as registration of the offering of the warrant shares, the filing of a Current Report on Form 8-K to disclose entering into these securities purchase agreements, the providing of material nonpublic information, use of proceeds, indemnification of purchasers, reservation and listing of common stock, and prohibitions on subsequent equity sales for 30 days.

Delivery of the securities offered hereby is expected to occur on or about September 17, 2025, subject to satisfaction of certain customary closing conditions.

Fees and Expenses

The following table shows the per share and accompanying Warrants, and per Pre-Funded Warrant and accompanying Warrants, and total placement agent fees we will pay in connection with the sale of the securities in this offering.

			Per Share and Accompanying Warrants			Per Pre- Funded Warrant and Accompanying Warrants			Total
Combined public offering price			$2.00			$1.9999			$9,999,992.50
Placement agent fees			$0.12			$​0.12			$​600,000.00
Proceeds to us, before expenses			$1.88			$1.8799			$9,399,992.50

We will reimburse the placement agent a nonaccountable expense allowance of $50,000, its legal fees and expenses and other out-of-pocket expenses in an amount up to $100,000, road show expenses in an amount up to $5,000, and its clearing expense in an amount up to $15,950 in connection with this offering. We estimate the total offering expenses of this offering that will be payable by us, excluding the placement agent fees and expenses, will be approximately $160,093. After deducting the placement agent fees and our estimated offering expenses, we expect the net proceeds from this offering to be approximately $9.0 million.

Tail

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

Determination of Offering Price

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

The placement agent may, in its sole discretion and without notice, waive the terms of any of these lock-up agreements. In addition, we have agreed to not issue any shares of common stock or securities exercisable or convertible into shares of common stock for a period of 30 days following the closing date of this offering, subject to certain exceptions, and to not issue any securities that are subject to a price reset based on trading prices of our common stock or upon a specified or contingent event in the future, or enter into an agreement to issue securities at a future determined price, until the date that is one year following the closing date of the offering.
