CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains “forward-looking statements” within the meaning of the federal securities laws, and that involve significant risks and uncertainties. Words such as “may,” “should,” “could,” “would,” “predicts,” “potential,” “continue,” “expects,” “anticipates,” “future,” “intends,” “plans,” “believes,” “estimates,” and similar expressions, as well as statements in future tense, identify forward-looking statements. Forward-looking statements should not be read as a guarantee of future performance or results and may not be accurate indications of when such performance or results will be achieved. Forward-looking statements are based on information we have when those statements are made or management’s good faith belief as of that time with respect to future events and are subject to significant risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Forward-looking statements are subject to a number of risks, uncertainties and assumptions in other documents we file from time to time with the SEC, specifically our most recent Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q and our Current Reports on Form 8-K.

Important factors that could cause such differences include, but are not limited to:

●

our projected financial position and estimated cash burn rate;

●

our estimates regarding expenses, future revenues and capital requirements;

●

our ability to continue as a going concern;

●

our need to raise substantial additional capital to fund our operations;

●

our ability to commercialize or monetize Proclarix and integrate the assets and commercial operations acquired in the share exchange with Proteomedix AG (“Proteomedix”);

● our reliance on third parties, including Laboratory Corporation of America (“~~LabCorp~~LapCorp”), to develop, market, distribute and sell Proclarix;

● the successful development of our commercialization capabilities, including sales and marketing capabilities;.

●

our ability to consummate the transaction on a timely basis as contemplated by the Share Exchange Agreement with Realbotix, LLC (“Realbotix” and the “Share Exchange Agreement” and the transactions contemplated therein, the “Realbotix Transaction”) and the anticipated benefits of the Realbotix Transaction.

●

our ability to maintain the necessary regulatory approvals to market and commercialize our product;

●

the results of market research conducted by us or others;

●

our ability to obtain and maintain intellectual property protection for our current products;

●

our ability to protect our intellectual property rights and the potential for us to incur substantial costs from lawsuits to enforce or protect our intellectual property rights;

●

the possibility that a third party may claim we or our third-party licensors have infringed, misappropriated, or otherwise violated their intellectual property rights and that we may incur substantial costs and be required to devote substantial time defending against claims against us;

iii

●

our reliance on third parties, including manufacturers and logistics companies;

●

the success of competing therapies or diagnostics and products that are or become available;

●

our ability to successfully compete against current and future competitors;

●

our ability to expand our organization to accommodate potential growth and our ability to attract, motivate and retain key personnel;

●

the potential for us to incur substantial costs resulting from product liability lawsuits against us and the potential for these product liability lawsuits to cause us to limit our commercialization of our products;

●

market acceptance of our products, the size and growth of the potential markets for our current products, and our ability to serve those markets; and

●

disruptions in the business of the Company or Proteomedix, which could have an adverse effect on their respective businesses and financial results.

These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described in “Risk Factors.” Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this prospectus may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. Moreover, except as required by law, neither we nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this prospectus to conform these statements to actual results or to changes in our expectations.

You should read this prospectus and the documents that we reference in this prospectus and have filed with the SEC as exhibits to the registration statement of which this prospectus forms a part with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect.

WeOur are a commercial stage biotechnology company focused on the research, development, and commercialization of innovative solutions for men’s health and oncology. Through our acquisition of Proteomedix, which closed on December 15, 2023, we own Proclarix, an in vitro diagnostic test for prostate cancer originally developed by Proteomedix and approved for sale in the European Union under the In Vitro Diagnostic Regulation (“IVDR”), which we anticipate will be marketed in the U.S. as a lab developed test through our license agreement with LabCorp.Company

We are currently focusing our efforts on commercializing Proclarix.

Proclarix is an easy-to-use next generation protein-based blood test that can be done with the same sample as a patient’s regular Prostate-Specific Antigen (“PSA”) test. The PSA test is a well-established prostate specific marker that measures the concentration of PSA molecules in a blood sample. A high level of PSA can be a sign of prostate cancer. However, PSA levels can also be elevated for many other reasons including infections, prostate stimulation, vigorous exercise or even certain medications. PSA results can be confusing for many patients and even physicians. It is estimated over 50% of biopsies with elevated PSA are negative or clinically insignificant resulting in an overdiagnosis and overtreatment that impacts the physician’s routine, our healthcare system, and the quality of patients’ lives. Approximately 10% of all men have elevated PSA levels., commonly referred to as the diagnostic “grey zone”, of which only 20 - 40% present clinically with cancer. Proclarix is intended for use in diagnosing these patients where it is difficult to decide if a biopsy is necessary to verify a potential clinically significant cancer diagnosis. Proclarix helps doctors and patients with unclear PSA test results through the use of our proprietary Proclarix Risk Score which delivers clear and immediate diagnostic support for further treatment decisions. No additional intervention is required, and results are available quickly. Local diagnostic laboratories can integrate this multiparametric test into their current workflow because Proclarix assays use the enzyme-linked immunosorbent assay (ELISA) standard, which most diagnostic laboratories are already equipped to process.

Since our inception in October 2018 until April 2023, when we acquired ENTADFI, we devoted substantially all of our resources to performing research and development, undertaking preclinical studies and enabling manufacturing activities in support of our product development efforts, hiring personnel, acquiring and developing our technology and now halted vaccine candidates, organizing and staffing our company, performing business planning, establishing our intellectual property portfolio and raising capital to support and expand such activities.

ENTADFI is an FDA-approved, once daily pill that combines finasteride and tadalafil for the treatment of BPH, a disorder of the prostate. However, in light of (i) the time and resources needed to continue pursuing commercialization of ENTADFI, and (ii) the Company’s cash runway and indebtedness, the Company abandoned commercialization of ENTADFI and no longer holds remaining inventory of the product as of December 31, 2025. In addition, as part of cost reduction efforts and in connection with our initial pause in commercializing ENTADFI, we terminated three employees involved with the ENTADFI program, effective April 30, 2024, with such individuals to continue assisting the Company on an as-needed, consulting basis. Based on the circumstances surrounding ENTADFI, at June 30, 2024, the ENTADFI assets were fully impaired. Refer to Note 4 in the consolidated financial statements for the period ended December 31, 2024 for further discussion.

Given Proclarix is CE-marked for sale in the European Union, we expect to generate revenue from sales of Proclarix by 2027. Although we anticipate these sales to offset some expenses relating to commercial scale up and development, we expect our expenses will increase substantially in connection with our ongoing activities, as we:

●

commercialize Proclarix;

●

hire additional personnel;

● operate as a public company; ~~and~~

● obtain, maintain, expand, and protect our intellectual property portfolio.; and

●

perform product validation studies in connection with a license agreement.

We rely and will continue to rely on third parties for the manufacturing of Proclarix. We have no internal manufacturing capabilities, and we will continue to rely on third parties, of which the main suppliers are single-source suppliers, for commercial product.

We do not have any products approved for sale, aside from ~~(i)~~ Proclarix. ~~and~~We ~~(ii) ENTADFI, which has not generated any revenue from product sales; we~~ have ~~determined to~~abandoned ~~abandon~~ commercialization of ENTADFI and ~~are~~have indestroyed ~~the process of destroying~~ our inventory of the product.

To date, we have financed our operations primarily with proceeds from our sale of preferred securities to seed investors, the initial public offering (“IPO”), and subsequent offerings of debt and equity securities. We will continue to require significant additional capital to commercialize Proclarix, and to fund operations for the foreseeable future. Accordingly, until such time as we can generate significant revenue, if ever, we expect to finance our cash needs through public or private equity or debt financings, third-party (including government) funding and to rely on third-party resources for marketing and distribution arrangements, as well as other collaborations, strategic alliances and licensing arrangements, or any combination of these approaches, to support our operations.

We have incurred net losses since inception and expect to continue to incur net losses in the foreseeable future. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending in large part on the timing of our preclinical studies, clinical trials and manufacturing activities, our expenditures on other research and development activities and commercialization activities. As of ~~June~~December 3031, 2025, ~~the Company~~we had cash of approximately $05.3 2 million, a working capital deficit of approximately $113.8 1 million and an accumulated deficit of approximately $~~128~~131.1 2 million. During the ~~six~~year ~~months~~ ended ~~June~~December 3031, 2025, ~~the~~we ~~Company~~ used approximately $39.4 7 million in cash for operating activities. In addition, as of ~~October~~April 3024, ~~2025~~2026, ~~the~~our ~~Company’s~~ cash balance was approximately $64.2 million. ~~The Company~~We ~~believes~~believe that ~~its~~our current cash balance is not sufficient to fund its operations ~~through~~for ~~August~~one ~~13,~~year ~~2026.~~from ~~When~~ the ~~Company~~date ~~can again~~of ~~utilize~~issuance of the ~~equity~~consolidated ~~line~~financial ofstatements ~~credit~~for ~~(“ELOC”)~~the ~~that~~year. ~~was~~While ~~established~~such bycapital araises may ~~certain~~enable ~~Common~~us ~~Stock~~to ~~ELOC~~sustain ~~Purchase~~current ~~Agreement,~~operations ~~dated as~~and ofmeet ~~October~~existing 2obligations, ~~2024,~~we bycontinue ~~and~~to ~~between~~generate usrecurring ~~and~~net anoperating ~~institutional~~losses ~~investor~~and have ~~(the~~not ~~“ELOC~~yet ~~Purchase~~established ~~Agreement”),~~sustained itpositive ~~may~~cash beflows ~~able~~ to ~~raise~~ upsupport toour ~~$17.9~~strategic ~~million~~growth ininitiatives. ~~gross~~Such ~~proceeds~~initiatives ~~remaining~~include ~~under~~ the ~~ELOC.~~commercialization of ~~However,~~Proclarix ~~given~~and ~~the~~our ~~terms~~development and commercialization of ~~the~~future ~~ELOC~~product ~~and~~candidates. ~~the~~These ~~uncertainty~~factors toraise ~~drawdown~~substantial doubt on our ability ~~fully~~to ~~from~~continue ~~the~~as ~~ELOC,~~a ~~there~~going ~~are~~concern nofor ~~assurances~~one ~~that~~year from the ~~Company~~date ~~may~~of ~~not~~issuance ~~have~~of ~~funds~~our toconsolidated ~~sustain~~financial ~~operations~~statements for the ~~next~~financial 12year ended ~~months~~December 31, 2025.

Until we generate revenue sufficient to support self-sustaining cash flows, if ever, we will need to raise additional capital to fund our continued operations, including our product development and commercialization activities related to our current and future products. There can be no assurance that additional capital will be available to us on acceptable terms, or at all, or that we will ever generate revenue sufficient to provide self-sustaining cash flows. These circumstances raise substantial doubt about our ability to continue as a going concern. The ~~condensed~~accompanying consolidated financial statements ~~incorporated~~of byOnconetix, ~~reference~~as of and for the year ended December 31, 2025, included elsewhere in this prospectus do not include any adjustment that might be necessary if the Company is unable to continue as a going concern.

Because of the numerous risks and uncertainties associated with our business, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Additionally, even if we are able to generate revenue from Proclarix, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and may be forced to reduce our operations.

On October 1, 2024, the Board authorized the Company to create a series of 10,000 shares of preferred stock designated as “Series C convertible Preferred Stock”, with a par value of $0.00001, pursuant to the certificate of designations. At any time after the initial issuance date of Series C convertible Preferred Stock, each Series C Preferred Share shall be convertible into validly issued, fully paid and non-assessable shares of Common Stock. The holders of Series C Preferred Stock are entitled to dividends, on an as-if converted basis, equal to and in the same form as dividends actually paid on shares of Common Stock, when and if actually paid. In addition, from and after the occurrence and during the continuance of any Triggering Event, dividends (“Default Dividends”) will accrue on the Stated Value of each Series C Preferred Share at a rate of fifteen percent (15.0%) (the “Default Rate”) per annum. Each holder is entitled to convert any portion of the outstanding Series C Preferred Shares held by such holder into validly issued, fully paid and non-assessable Conversion shares at the Conversion Rate, which can be determined by dividing (x) the Conversion Amount of such Series C Preferred Share by (y) the Conversion Price, $4.5056, subject to adjustment as provided in the Certificate of Designations.

On October 2, 2024, the Company also entered into the ELOC Purchase Agreement with an institutional investor (the “ELOC Purchaser”), whereby the Company may offer and sell, from time to time at its sole discretion, and whereby the ELOC Purchaser has committed to purchase, up to $25.0 million of the Company’s newly issued Common Stock, subject to the limitations described herein. Concurrently with entering into the ELOC Purchase Agreement, the Company also entered into a registration rights agreement with the ELOC Purchaser, pursuant to which it agreed to provide the ELOC Purchaser with certain registration rights related to the shares issued under the ELOC Purchase Agreement (the “ELOC Registration Rights Agreement”).

As of June 30, 2025, an aggregate of 2,130 shares of Series C Preferred Stock were outstanding, after redemptions of 1,369 shares for an aggregate of $1.71 million. As a result of draws on the ELOC in April and June 2025, an additional 329 shares of Series C preferred stock were to be redeemed for an aggregate amount of $409,510.

On July 16, 2025, the Company exercised its voluntary Series C adjustment right to lower the conversion price of the Series C preferred stock to $3.50, and holders of 2,130 shares Series C Preferred Stock agreed to convert their shares into shares of common stock.

Conversion of Company Convertible Securities

Prior to the consummation of the Share Exchange, the holders of Realbotix Convertible Securities will exercise their rights to receive Realbotix Interests pursuant to the terms of such Realbotix Convertible Securities (as defined below) at the applicable conversion ratio as set forth in the Realbotix Convertible Securities (the “Realbotix Convertible Securities Conversion”). Upon completion of the Realbotix Convertible Securities Conversion and prior to Closing, all Realbotix Convertible Securities will be canceled or terminated, as applicable, will no longer be outstanding and will cease to exist and no payment or distribution will be made with respect thereto. Each holder of Realbotix Convertible Securities thereafter will cease to have any rights with respect to such securities.

Closing Conditions

The consummation of the Share Exchange is subject to customary closing conditions, including (i) the accuracy of the representations and warranties of the parties (subject to customary materiality qualifiers); (ii) compliance in all material respects by the parties with their respective covenants and agreements under the Share Exchange Agreement; (iii) delivery of customary closing certificates and good standing certificates; (iv) receipt by Board of a fairness opinion; (v) the absence of any law, order or injunction prohibiting the consummation of the Realbotix Transactions and (vi) receipt of any required third-party and regulatory approvals and consents.

The obligation of the Realbotix, Parent and Seller to complete the Closing is subject to the condition that, at Closing, we shall have an aggregate of at least $12.5 million in Net Cash (the “Net Cash Condition”).

Additionally, the obligation of Realbotix, Parent and us to complete the Closing are subject to the conditions that (i) we have entered into an agreement with an investor, reasonably acceptable to us and Realbotix, providing for an equity line of credit pursuant to which such investor would commit to purchase up to an aggregate of $125.0 million of Common Stock and (ii) the conversion of our Preferred Stock into Common Stock and the termination of or certain amendments to of all Onconetix Options and Onconetix Warrants (the “Convertible Securities Condition”).

Termination

In addition to termination by mutual written agreement, for the other party’s uncured breach or if a governmental order permanently prohibits the Closing, the Share Exchange Agreement provides for termination:

●

By either party if the Closing has not been consummated on or before November 30, 2026, provided the terminating party is not in breach in a manner that caused the failure to close by such date. The date is automatically extended to December 20, 2026 if all conditions to Closing other than the Net Cash Condition have been satisfied.

●

By either party if our stockholder approval is not obtained at the stockholder meeting (including any adjournment or postponement thereof).

●

By Realbotix if a Buyer Adverse Recommendation Change (as defined in the Share Exchange Agreement) occurs prior to receipt of Buyer stockholder approval.

●

By us in connection with entering into a definitive agreement for a Buyer Superior Proposal (as define in the Share Exchange Agreement).

●

By us if the audited Realbotix financial statements have not been delivered by April 30, 2026.

Each party will bear its own fees and expenses incurred in connection with the negotiation, execution and performance of the Share Exchange Agreement and the Realbotix Transactions. However, the Share Exchange Agreement provides for the payment of termination fees and reimbursement of transaction expenses in the following termination scenarios:

●

In the event of a termination of the Share Exchange Agreement as a result of a material breach by either party, the breaching party will be required to pay a termination fee to the non-breaching party of $500,000 plus transaction expenses, with such transaction expenses not to exceed $500,000.

●

In the event of a termination of the Share Exchange Agreement (i) by the Company as the result of a Buyer Adverse Recommendation Change or (ii) by Buyer upon entering into an agreement in respect of a Buyer Superior Proposal as a result of a Buyer Adverse Recommendation Change, Buyer must pay a termination fee of (A) $500,000 plus all Seller transaction expenses plus (B) if the transaction in respect of a Buyer Superior Proposal closes, an additional $1,500,000 upon closing of such transaction. If the transaction contemplated by the Buyer Superior Proposal doesn’t close, Buyer is only obligated to pay $500,000 plus all Seller transaction expenses.

●

In the event of a termination of the Share Exchange Agreement by Realbotix for failure to satisfy the Net Cash Condition, if Net Cash at the time of termination would be greater than $5.0 million (assuming the consummation of any Transaction Financing pursuant to Financing Agreements), we are obligated to pay Realbotix’s transaction expenses, with such transaction expenses not to exceed $500,000.

Representations and Warranties

We, Realbotix, and the Seller have made customary representations and warranties in the Share Exchange Agreement. The representations and warranties of us, Realbotix, and the Seller will not survive the Closing.

Covenants of the Parties

The exercise price of the Series E Warrants iswas $319.~~8576~~288 on a post-reverse split basis, and further reduced to $0.7298 per share as a result of anti-dilution contained in the Series E Warrant. The Series E Warrants are exercisable beginning on the issuance date and expire on the third anniversary of the issuance date.

Concurrently with entering into the Series E Securities Purchase Agreement, the Company also entered into a registration rights agreement with the Series E PIPE Investors, pursuant to which it has agreed to provide the Series E PIPE Investors with certain registration rights related to the shares of Common Stock underlying the shares of Series E Preferred Stock and Series E Warrants.

4Series D PIPE Financing

On September 22, 2025, the Company entered into a securities purchase agreement (the “Series D Securities Purchase Agreement”) with eleven institutional investors, and sold or exchanged debt, to such investors (collectively, the “Series D PIPE Investors”) an aggregate of 16,099 shares of Series D convertible preferred stock, par value $0.00001 per share (“Series D Preferred Stock”), which includes an issuance of 500 shares of Series D Preferred Stock to the lead investor in consideration for the Series D PIPE Investors’ irrevocable commitment to purchase shares of the Series D Preferred Stock, and warrants (the “Series D Warrants”) to purchase 872,565 shares of Common Stock on a post-reverse split basis, for an aggregate purchase price of approximately $12.9 million and net cash proceeds of $9.3 million. The exercise price of the Series D Warrants was $18.448 on a post-reverse split basis and further reduced to $0.7298 per share as a result of anti-dilution contained in the Series D Warrant. The Series D Warrants are exercisable beginning on the issuance date and expire on the third anniversary of the issuance date.

Concurrently with entering into the Series D Securities Purchase Agreement, the Company also entered into a registration rights agreement with the Series D PIPE Investors, pursuant to which it has agreed to provide the Series D PIPE Investors with certain registration rights related to the shares of Common Stock underlying the shares of Series D Preferred Stock and Series D Warrants.

Amendment to Series D and Series E Warrants

On December 23, 2025, the Company entered into Limited Waiver Agreements (the “Warrant Limited Waiver”) with all holders of the Series D and Series E Warrants, effective as of October 1, 2025, pursuant to which such holders agreed to waive certain provisions of their Series D Warrants and Series E Warrants. Specifically, in the event the Company issues securities with a conversion price dependent on the price of the Common Stock (the “Variable Price”), the holders of Series D Warrants and Series E Warrants will no longer have the optional right to convert their applicable Series D Warrants and Series E Warrants at the Variable Price.

Additionally, the Warrant Limited Waiver waived the right of the Series D Warrants and the Series E Warrants to receive a guaranteed cash payment in connection with a “Fundamental Transaction” (as such term is defined in the Series D Warrants and Series E Warrants). Instead, in connection with a “Fundamental Transaction” that is not within the Company’s control, the holders of Series D Warrants and Series E Warrants are entitled only to receive the same form and proportion of consideration (or deemed common stock of the successor entity, if no such consideration is paid) as is offered and paid to holders of Common Stock, the definition of “Fundamental Transaction” in Series D Warrants and the Series E Warrants was further amended by the Warrant Limited Waiver to replace each reference to “at least” 50% with “more than” 50% of the outstanding Common Stock.

Termination of Ocuvex Business Combination Agreement

On July 16, 2025, the Company entered into an Agreement and Plan of Merger with (i) Onconetix Merger Sub, Inc., a Delaware corporation and a direct, wholly owned subsidiary of the Company, and (ii) Ocuvex Therapeutics, Inc., a Delaware corporation (“Ocuvex”, and such agreement, the “Ocuvex Merger Agreement”). Pursuant to the Merger Agreement, Merger Sub will merge with and into Ocuvex, with Ocuvex surviving the merger as a direct, wholly owned subsidiary of the Company (the “Ocuvex Merger” and the other transactions contemplated by the Merger Agreement, the “Ocuvex Transactions”).

Effective September 24, 2025, pursuant to Section 9.01(a) of the Merger Agreement, Ocuvex and the Company entered into a Termination and Release Agreement (the “Termination Agreement”) pursuant to which they agreed to terminate the Ocuvex Merger Agreement and the transactions contemplated thereby. The Termination Agreement also terminates and makes void the ancillary documents entered by and among Ocuvex and the Company in connection with the Ocuvex Merger Agreement. The Termination Agreement also provides for a mutual release of claims among the Parties and their affiliates and in consideration of the foregoing, the Company agreed to pay to Ocuvex, an amount equal to $302,343.55 (the “Termination Payment”), which represents all amounts payable by the Company to Ocuvex pursuant to Section 6.02(f) of the Merger Agreement.

As of September 24, 2025, Ocuvex confirmed receipt of the Termination Payment, and as a result the Ocuvex Merger Agreement is of no further force and effect.

Series C PIPE Financing

On October 1, 2024, the Board authorized the Company to create a series of 10,000 shares of preferred stock designated as “Series C convertible Preferred Stock”, with a par value of $0.00001, pursuant to the certificate of designations. At any time after the initial issuance date of Series C convertible Preferred Stock, each Series C Preferred Share shall be convertible into validly issued, fully paid and non-assessable shares of Common Stock. The holders of Series C Preferred Stock are entitled to dividends, on an as-if converted basis, equal to and in the same form as dividends actually paid on shares of Common Stock, when and if actually paid. In addition, from and after the occurrence and during the continuance of any Triggering Event, dividends (“Default Dividends”) will accrue on the Stated Value of each Series C Preferred Share at a rate of fifteen percent (15.0%) (the “Default Rate”) per annum. Each holder is entitled to convert any portion of the outstanding Series C Preferred Shares held by such holder into validly issued, fully paid and non-assessable Conversion shares at the Conversion Rate, which can be determined by dividing (x) the post-reverse split Conversion Amount of such Series C Preferred Share by (y) the post-reverse split Conversion Price, $22.528, subject to adjustment as provided in the Series C Certificate of Designations.

On October 2, 2024, the Company entered into, and sold, to six institutional investors (collectively, the “PIPE Investors”), pursuant to the securities purchase agreement an aggregate of 3,499 shares of Series C Preferred Stock which includes an issuance of 840 shares of Series C Preferred Stock to the lead investor in consideration for the PIPE Investors’ irrevocable commitment to purchase shares of the Series C Preferred Stock, and warrants to purchase 1,392 shares of Common Stock on a post-reverse split basis for aggregate net cash proceeds to the Company of $1.9 million. The exercise price of the warrants is $1,862.50 on a post-reverse split basis, and the warrants are exercisable six months after the issuance date and expire on the third anniversary of the Initial Exercisability Date.

In no event may any Series C Preferred Shares be converted (or Series C Warrants be exercised) and shares of Common Stock be issued to any holder if after giving effect to the issuance of shares of Common Stock upon such conversion of the Series C Preferred Shares (or exercise of the Series C Warrants), the holder (together with its affiliates, if any) would beneficially own more than 4.99% of the outstanding shares of Common Stock, which we refer to herein as the “Series C PIPE Blocker”. The Series C PIPE Blocker may be raised or lowered to any percentage not in excess of 9.99% at the option of the applicable holder of the Series C Preferred Shares (or Series C Warrants), except that any raise will only be effective upon 61-days’ prior notice to the Company.

On July 16, 2025, the Company exercised its voluntary adjustment right under the Series C to lower the conversion price of the Series C Preferred Stock, until July 31, 2025, to a post-reverse split of $17.50, and holders of 2,130 shares Series C Preferred Stock agreed to convert their shares into shares of Common Stock. As of September 30, 2025, 7 shares of Series C Preferred Stock were outstanding, after the exchange of 203 shares of Series C Preferred Stock into 244 shares of Series D Preferred Stock.

As of December 31, 2025, 7 shares of Series C Preferred Stock were outstanding from the original issuance of 3,499 shares of Series C Preferred Stock to institutional investors, after the i) redemption of 1,369 shares of Series C Preferred Stock for aggregate consideration of $1.71 million, ii) the conversion of 1,920 shares of Series C Preferred Stock into shares of Common Stock, and iii) the exchange of 203 shares of Series C Preferred Stock into 244 shares of Series D Preferred Stock.

Our inability to access a portion or the ~~value~~full amount available under the ELOC Purchase Agreement, in the absence of any other financing sources, could have a material adverse effect on our ~~Common~~business ~~Stock~~or results of operation.

Keystone will pay less than the then-prevailing market price for our Common Stock, which could cause the price of our Common Stock to decline.

The purchase price of our Common Stock to be sold to Keystone under the ELOC Purchase Agreement is derived from the market price of our Common Stock on Nasdaq. Shares to be sold to Keystone pursuant to the ELOC Purchase Agreement will be purchased at a discounted price.

For example, we may effect sales to Keystone pursuant to a Fixed Purchase Notice (as defined below) at a purchase price equal to the lesser of 90% of (i) the daily VWAP (as defined below) of the Common Stock for the five trading days immediately preceding the applicable Fixed Purchase Date (as defined below) and (ii) the closing price of a share of Common Stock on the applicable Fixed Purchase Date during the full trading day on such applicable Purchase Date. See “Keystone Committed Equity Financing” for more information.

As a result of this pricing structure, Keystone may sell the shares they receive immediately after receipt of such shares, which could cause the price of our Common Stock to decrease.

Investors who buy shares of Common Stock from Keystone at different times will likely pay different prices.

Pursuant to the ELOC Purchase Agreement, we have discretion, to vary the timing, price and number of shares of Common Stock we sell to Keystone. If and when we elect to sell shares of Common Stock to Keystone pursuant to the ELOC Purchase Agreement, after Keystone has acquired such shares, Keystone may resell all, some or none of such shares at any time or from time to time in its sole discretion and at different prices. As a result, investors who purchase shares from Keystone in this offering at different times will likely pay different prices for those shares, and so may experience different levels of dilution and in some cases substantial dilution and different outcomes in their investment results. Investors may experience a decline in the value of the shares they purchase from Keystone in this offering as a result of future sales made by us to Keystone at prices lower than the prices such investors paid for their shares in this offering. In addition, if we sell a substantial number of shares to Keystone under the ELOC Purchase Agreement, or if investors expect that we will do so, the actual sales of shares or the mere existence of our arrangements with Keystone may make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect such sales.

Future resales and/or issuances of shares of Common Stock, including pursuant to this prospectus, or the perception that such sales may occur, may cause the market price of our shares to drop significantly.

The shares of our Common Stock that may be issued under the ELOC Purchase Agreement may be sold by us to Keystone at our discretion from time to time from the date of effectiveness of effectiveness of the registration statement of which this prospectus forms a part until the earliest to occur of (i) the 36-month anniversary of the effective date of the registration statement of which this prospectus forms a part, (ii) the date on which Keystone has purchased the Aggregate Limit pursuant to the ELOC Purchase Agreement, (iii) the date on which our Common Stock fails to be listed or quoted on Nasdaq or any successor Eligible Market (as defined in the ELOC Purchase Agreement), and (iv) the date on which, pursuant to or within the meaning of any bankruptcy law, a custodian is appointed for us or for all or substantially all of our property, or we make a general assignment for the benefit of our creditors.

The purchase price for shares of our Common Stock that we may sell to Keystone under the ELOC Purchase Agreement will fluctuate based on the trading price of shares of our Common Stock. Depending on market liquidity at the time, sales of shares of our Common Stock may cause the trading price of shares of our Common Stock to decrease. We generally have the right to control the timing and amount of any future sales of shares of our Common Stock to Keystone. Additional sales of shares of our Common Stock, if any, to Keystone will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Keystone all, some or none of the additional shares of our Common Stock that may be available for us to sell pursuant to the ELOC Purchase Agreement. If and when we do sell shares of our Common Stock to Keystone, after Keystone has acquired shares of our Common Stock, Keystone may resell all, some or none of such shares of our Common Stock at any time or from time to time in its discretion and at different prices. Therefore, sales to Keystone by us could result in substantial dilution to the interests of other holders of shares of our Common Stock. In addition, if we sell a substantial number of shares of our Common Stock to Keystone under the ELOC Purchase Agreement, or if investors expect that we will do so, the shares held by Keystone will represent a significant portion of our public float and may result in substantial decreases to the price of our Common Stock. The actual sales of shares of our Common Stock or the mere existence of our arrangement with Keystone may also make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect such sales.

The market price of shares of our Common Stock could drop significantly if Keystone sells shares of Common Stock or is perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of shares of our Common Stock or other securities.

We may use proceeds from sales of our Common Stock made pursuant to the ELOC Purchase Agreement in ways with which you may not agree or in ways which may not yield a significant return.

We will have broad discretion over the use of proceeds from sales of our Common Stock made pursuant to the ELOC Purchase Agreement, including for any of the purposes described in the section entitled “Use of Proceeds,” and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of the net proceeds, their ultimate use may vary substantially from their currently intended use. While we expect to use the net proceeds from this offering as set forth in “Use of Proceeds,” we are not obligated to do so. The failure by us to apply these funds effectively could harm our business, and the net proceeds may be used for corporate purposes that do not increase our operating results or enhance the value of our Common Stock.

Other Risks

Risks Related to our Financial Position and Need for Capital

We have incurred significant net losses since inception, have only generated minimal revenue, and anticipate that we will continue to incur substantial net losses for the foreseeable future and may never achieve profitability. Our stock is a highly speculative investment.

We are a commercial-stage biotechnology company that was incorporated in October 2018. Our net loss was $1014.90 million and $58.7 million for the ~~six~~years ~~months~~ ended ~~June 30~~December 31, 2025 and 2024, respectively. As of ~~June~~December 3031, 2025, we had an accumulated deficit of $~~128~~131.12 million. We also generated negative operating cash flows of $39.47 million for the ~~six~~year ~~months~~ ended ~~June~~December 3031, 2025.

We expect to continue to spend significant resources to commercialize our product. We expect to incur substantial and increasing operating losses over the next several years. As a result, our accumulated deficit will also increase significantly. Additionally, there can be no assurance that our current product or those that may be under development by us in the future will be commercially viable. If we are unable to achieve profitability or raise sufficient working capital, we may be unable to continue our operations.

There is substantial doubt about our ability to continue as a “going concern,” and we will require substantial additional funding to finance our long-term operations. If we are unable to raise additional capital when needed, we could be forced to delay, reduce or terminate our product or other operations.

~~The~~We ~~Company~~have ~~has~~ incurred ~~substantial~~ substantial operating losses since inception and expects to continue to incur significant operating losses for the foreseeable future. As of ~~June 30~~December 31, 2025, ~~the~~we ~~Company~~ had cash of approximately $05.32 million, a working capital deficit of approximately $113.81 million and an accumulated deficit of approximately $~~128~~131.12 million. In addition, as of ~~October~~April 3024, ~~2025~~2026, ~~the~~our ~~Company’s~~ cash balance was approximately $64.2 million.

6We estimate, as of the date of this prospectus, that our current cash balance is not sufficient to fund operations for one year from the date of issuance of these consolidated financial statements. We believe that we will need to raise substantial additional capital to fund our continuing operations, satisfy existing and future obligations and liabilities, and otherwise support the our working capital needs and business activities, including the commercialization of Proclarix, which is still subject to further successful development and commercialization activities within certain jurisdictions.

We ~~estimate,~~have asentered ofinto ~~the date~~Series ofD ~~this~~and ~~prospectus,~~Series ~~that~~E ~~our~~PIPE ~~current~~financings ~~cash~~with ~~balance~~certain isinvestors ~~not~~in ~~sufficient~~September 2025 and October 2025, respectively which provided us additional cash flow to ~~fund~~support our near-term operations. ~~through~~While ~~the~~such ~~end~~capital ofraises ~~August~~may ~~2026.~~enable Weus ~~believe~~to ~~that~~sustain current operations and meet existing obligations, we ~~will~~continue ~~need~~ to ~~raise~~generate ~~substantial~~recurring ~~additional~~net ~~capital~~operating losses and have not yet established sustained positive cash flows to ~~fund~~support our ~~continuing~~strategic growth ~~operations,~~initiatives. ~~satisfy~~Such ~~existing~~initiatives include the commercialization of Proclarix and ~~future~~our ~~obligations~~development and ~~liabilities,~~commercialization of future product ~~and~~candidates. ~~otherwise~~These ~~support~~factors ~~the~~raise ~~Company’s~~substantial ~~working~~doubt ~~capital~~on ~~needs~~our ~~and~~ability ~~business~~to ~~activities~~continue ~~and~~as a going concern for one year from the ~~commercialization~~date of ~~Proclarix, which~~issuance isof ~~still~~our ~~subject~~consolidated tofinancial ~~further~~statements ~~successful~~for ~~development~~the ~~and~~financial ~~commercialization~~year ~~activities~~ended ~~within~~December ~~certain~~31, ~~jurisdictions~~2025.

Management also intends to secure additional required funding through equity or debt financings if available. In December 2024, the Company began utilizing the ELOC entered into in October 2024 on an as-needed basis to fund current operating needs, subject to certain restrictions and beneficial ownership constraints. However, based on the terms of the ELOC and the current maximum availability, management determined that the funds readily available under the ELOC will not be sufficient to sustain operations. In addition, there are currently no other commitments in place for further financing nor is there any assurance that such financing will be available to the Company on favorable terms, if at all. This creates significant uncertainty whether the Company will have the funds available to be able to sustain its operations and expand commercialization of Proclarix. If the Company is unable to secure additional capital, it may be required to curtail any future clinical trials, development and/or commercialization of future product candidates, and it may take additional measures to reduce expenses in order to conserve its cash in amounts sufficient to sustain operations and meet its obligations, or, if it’s required to, file for bankruptcy.13

~~These~~Our management ~~conditions~~plans ~~raise~~for ~~substantial~~funding our operations include generating product revenue from sales of Proclarix, which is currently subject to ~~doubt~~further ~~about~~successful ~~the~~development ~~Company’s~~and ~~ability~~commercialization activities within certain jurisdictions.

If additional capital ~~requirements~~is ~~will~~not ~~depend~~secured, onwe ~~many~~may ~~factors~~need to curtail clinical trials, ~~including:~~development, and commercialization efforts, and take further measures to reduce expenses to conserve cash.

Our future capital requirements will depend on many factors, including:

●

the costs of future development and commercialization activities, including product manufacturing, marketing, sales, royalties and distribution, for Proclarix, and other products for which we have received or will receive marketing approval;

●

our ability to maintain existing, and establish new, strategic collaborations, licensing or other arrangements and the financial terms of any such agreements, including the timing and amount of any future milestone, royalty, or other payments due under any such agreement;

●

any product liability or other lawsuits related to our product;

●

the expenses needed to attract, hire, and retain skilled personnel;

●

the revenue, if any, received from commercial sales of Proclarix or other products for which we may receive marketing approval;

●

the costs to establish, maintain, expand, enforce, and defend the scope of our intellectual property portfolio, including the amount and timing of any payments we may be required to make, or that we may receive, in connection with licensing, preparing, filing, prosecuting, defending, and enforcing our patents or other intellectual property rights; and

●

the costs of operating as a public company.

Our ability to raise additional funds will depend on financial, economic, and other factors, many of which are beyond our control. We cannot be certain that additional funding will be available on acceptable terms, or at all. We have no committed source of additional capital and if we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may be forced to delay, reduce or terminate our business activities.

We are dependent on third parties, including Labcorp, to develop, market, distribute and sell our products.

Our ability to receive revenues is dependent upon the sales and marketing efforts of co-marketing partners and third-party distributors. In particular, the development and commercialization of Proclarix in the United States is being pursued by Labcorp, pursuant to an exclusive license agreement that grants Labcorp the exclusive right to develop and commercialize Proclarix, and other products developed by Labcorp using Proteomedix’s intellectual property covered by the license, in the United States for identification, screening, staging, predisposition, diagnosis, prognosis, monitoring, prevention or treatment selection with respect to prostate cancer. However, we do not have control over Labcorp’s development and commercialization of Proclarix, and there can be no guarantee that Labcorp will continue to advance development and commercialization efforts, or that Labcorp will successfully commercialize Proclarix in the United States.

Labcorp may terminate or seek to renegotiate the terms of this agreement, which could adversely affect our business operations and financial condition. If Labcorp terminates the agreement or demands terms that are less favorable to us, we may experience disruptions in our product development and commercialization efforts, potentially leading to a loss of revenue and market share.

Additionally, if Labcorp is unable to commercialize Proclarix in the United States, and we fail to reach an agreement with any other commercialization partner, or upon reaching such an agreement that partner fails to sell a large volume of our products, it may have a negative impact on our business, financial condition, and results of operations.

Ranking. Except (i) for the Series C Preferred Stock of the Company, which shall be of pari passu rank to the Series D Preferred Shares (the “Parity Stock”), and (ii) to the extent that the Required Holders (as defined in the Series D Securities Purchase Agreement) expressly consent to the creation of Parity Stock or Senior Preferred Stock, all shares of capital stock of the Company will be junior in rank to all Series D Preferred Shares with respect to the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding up of the Company.

Dividends. The holders of Series D Preferred Stock are entitled to dividends (the “Dividends”), when and as declared by the Company’s Board, from time to time, in its sole discretion, which Dividends shall be paid by the Company out of funds legally available therefor, payable, subject to the conditions and other terms hereof, in cash, in securities of the Company or any other entity, or using assets as determined by the Board on the Stated Value of such Series D Preferred Share. In addition, from and after the occurrence and during the continuance of any Triggering Event, dividends (“Default Dividends”) will accrue on the Stated Value of each Series D Preferred Share at a rate of fifteen percent (15.0%) (the “Default Rate”) per annum. Default Dividends are payable by way of inclusion of Default Dividends in the Conversion Amount (as defined below) on each conversion date. In the event that such Triggering Event is subsequently cured (and no other Triggering Event then exists), the accrual of Default Dividends will cease to be effective as of the calendar day immediately following the date of such cure; provided that Default Dividends as calculated and unpaid during the continuance of such Triggering Event will continue to apply to the extent relating to the days after the occurrence of such Triggering Event through and including the date of such cure of such Triggering Event.

Conversion Rights:

Conversion at Option of Holder. Each holder is entitled to convert any portion of the outstanding Series D Preferred Shares held by such holder into validly issued, fully paid and non-assessable Conversion Shares at the Conversion Rate (as defined below). Except as otherwise provided in the Series D Certificate of Designations, the number of Conversion Shares issuable upon conversion of any Series D Preferred Share will be determined by dividing (x) the Conversion Amount (as defined below) of such Series D Preferred Share by (y) the Conversion Price (the “Conversion Rate”). As used herein, the term “Conversion Amount” means, with respect to each Series D Preferred Share, as of the applicable date of determination, the sum of (1) the Stated Value thereof plus (2) any Default Dividends thereon as of such date of determination plus (3) any other amounts owed to such PIPE Investor pursuant to the terms of the Series D Certificate of Designations or any other Transaction Document; and the term “Conversion Price” means, with respect to each Series D Preferred Share, as of any Conversion Date or other date of determination, $3.6896, subject to adjustment as provided in the Series D Certificate of Designations.

Conversion at the Option of the Holder Upon the Occurrence of a Triggering Event. After the Stockholder Approval Date (as defined in the Series D Securities Purchase Agreement), if a Triggering Event occurs and is continuing, at any time after the earlier of a holder’s receipt of a Triggering Event Notice (as defined below) and such holder becoming aware of such Triggering Event (such earlier date, the “Alternate Conversion Right Commencement Date”) and ending on the twentieth (20th) Trading Day (as defined in the Series D Securities Purchase Agreement) after the later of (x) the date such Triggering Event is cured and (y) such holder’s receipt of a Triggering Event Notice (such ending date, the “Alternate Conversion Right Expiration Date”, and each such period, an “Alternate Conversion Right Period”), such holder may, at such holder’s option, by delivery of a Conversion Notice to the Company (the date of any such Conversion Notice, each an “Alternate Conversion Date”), convert all, or any number of Series D Preferred Shares held by such holder into shares of Common Stock at the Alternate Conversion Price (each, an “Alternate Conversion”). Additionally, at any time after the Stockholder Approval Date, the Holder may convert any number of Series D Preferred Shares held by such Holder at the Alternate Optional Conversion Price.

As used herein:

“Alternate Conversion Price” means, with respect to any Alternate Conversion that price which will be the lowest of (i) the applicable Conversion Price as in effect on the applicable Conversion Date of the applicable Alternate Conversion, and (ii) the greater of (x) the Floor Price (as defined below) and (y) 90% of the lowest VWAP of the Common Stock during the five (5) consecutive Trading Day period ending and including the Trading Day immediately preceding the delivery or deemed delivery of the applicable Conversion Notice (such period, the “Alternate Conversion Measuring Period”). All such determinations to be appropriately adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction that proportionately decreases or increases the Common Stock during such Alternate Conversion Measuring Period.

“Alternate Conversion Floor Amount” means an amount equal to the product obtained by multiplying (A) the higher of (i) the highest price that the Common Stock trades at on the Trading Day immediately preceding the relevant Alternate Conversion Date and (ii) the applicable Alternate Conversion Price and (B) the difference obtained by subtracting (i) the number of shares of Common Stock delivered (or to be delivered) to such holder on the applicable Share Delivery Deadline (as defined in the Series D Certificate of Designations) with respect to such Alternate Conversion from (ii) the quotient obtained by dividing (x) the applicable Conversion Amount that such holder has elected to be the subject of the applicable Alternate Conversion, by (y) the applicable Alternate Conversion Price, without giving effect to the Floor Price.

“Alternate Optional Conversion Price” means, with respect to any Alternate Conversion that price which will be the lowest of (i) the applicable Conversion Price as in effect on the applicable Conversion Date of the applicable Alternate Conversion, and (ii) the greater of (x) the Floor Price and (y) 95% of the lowest VWAP of the Common Stock during the five (5) consecutive Trading Day period ending and including the Trading Day immediately preceding the delivery or deemed delivery of the applicable Conversion Notice (such period, the “Alternate Optional Conversion Measuring Period”). All such determinations to be appropriately adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction that proportionately decreases or increases the Common Stock during such Alternate Optional Conversion Measuring Period.

“Floor Price” means $0.7379 (as adjusted for stock splits, stock dividends, stock combinations, recapitalizations and similar events), or, subject to the rules and regulations of the Principal Market (as defined in the Series D Certificate of Designations), such lower price as the Company and the Required Holders may agree, from time to time.

“Triggering Event Notice” means written notice from the Company delivered to each holder within two Business Days (as defined in the Series D Securities Purchase Agreement) after the occurrence of a Triggering Event) that includes (i) a reasonable description of the applicable Triggering Event, (ii) a certification as to whether, in the reasonable opinion of the Company, such Triggering Event is capable of being cured and, if applicable, a reasonable description of any existing plans of the Company to cure such Triggering Event and (iii) a certification as to the date the Triggering Event occurred and, if cured on or prior to the date of such Triggering Event Notice, the applicable Alternate Conversion Right Expiration Date.

“Triggering Event” includes, but is not limited to, the following, subject to certain cure periods as set forth in the Series D Certificate of Designations:

(i) the failure to file a registration statement for the resale of the shares of Common Stock underlying the Series D Preferred Shares and the Warrants, or the failure of the applicable registration statement to be declared effective by the SEC, ten (10) days after the applicable deadline;

(iii) the suspension from trading or the failure of the Common Stock to be trading or listed (as applicable) on an Eligible Market for a period of five (5) consecutive Trading Days;

(iv) failure to cure a Conversion Failure or a Delivery Failure (as defined in the Warrants) by delivery of the required number of shares of Common Stock within the requisite time frame;

(xii) the Company and/or any Subsidiary, individually or in the aggregate, either (i) fails to pay, when due, or within any applicable grace period, any payment with respect to any Indebtedness in excess of $500,000 due to any third party (other than, with respect to unsecured Indebtedness only, payments contested by the Company and/or such Subsidiary (as the case may be) in good faith by proper proceedings and with respect to which adequate reserves have been set aside for the payment thereof in accordance with GAAP) or is otherwise in breach or violation of any agreement for monies owed or owing in an amount in excess of $500,000, which breach or violation permits the other party thereto to declare a default or otherwise accelerate amounts due thereunder, or (ii) suffer to exist any other circumstance or event that would, with or without the passage of time or the giving of notice, result in a default or event of default under any agreement binding the Company or any Subsidiary, which default or event of default would or is likely to have a material adverse effect on the business, assets, operations (including results thereof), liabilities, properties, condition (including financial condition) or prospects of the Company or any of its Subsidiaries, individually or in the aggregate;

(xix) any provision of any Transaction Document will at any time for any reason (other than pursuant to the express terms thereof) cease to be valid and binding on or enforceable against the Company, or the validity or enforceability thereof is contested.

Stock Combination Event Adjustment. In addition to the adjustments set forth above, if at any time and from time to time on or after Stockholder Approval, there occurs any share split, share dividend, stock combination recapitalization or other similar transaction involving the Common Stock (each, a “Stock Combination Event”, and such date thereof, the “Stock Combination Event Date”) and the lowest VWAP during the ten consecutive (10) Trading Day period ending and including the fifth (5) Trading Day immediately preceding the Stock Combination Event Date (the “Event Market Price”) (provided if the Stock Combination Event is effective after close of trading on the primary Trading Market, then commencing on the next Trading Day which period will be the “Stock Combination Adjustment Period”) is less than the Conversion Price then in effect, then at the close of trading on the primary Trading Market on the last day of the Stock Combination Adjustment Period, the Conversion Price then in effect on such fifth (5th) Trading Day will be reduced (but in no event increased) to the Event Market Price, but not less than the Floor Price. Notwithstanding the foregoing, if one or more Stock Combination Events occur prior to Stockholder Approval being obtained and a reduction of the Conversion Price did not occur, once Stockholder Approval is obtained, the Conversion Price will automatically be reduced to equal the lowest Event Market Price with respect to any Stock Combination Event that occurred prior to Stockholder Approval being obtained, but not less than the Floor Price.

Adjustments for Variable Price Security Issuances. If the Company in any manner issues or sells or enters into any agreement to issue or sell, any Common Stock, Options or Convertible Securities (other than with respect to a Permitted Equity Line (as defined in the Series D Securities Purchase Agreement)) (any such securities, “Variable Price Securities”) after the Subscription Date (as defined in the Series D Certificate of Designations) that are issuable pursuant to such agreement or convertible into or exchangeable or exercisable for shares of Common Stock at a price which varies or may vary with the market price of the shares of Common Stock, including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting share splits, share combinations and share dividends (each of the formulations for such variable price being herein referred to as, the “Variable Price”), the Company shall provide written notice thereof via electronic mail and overnight courier to each Holder on the date of such agreement and/or the issuance of such shares of Common Stock, Convertible Securities or Options, as applicable. From and after the date the Company enters into such agreement or issues any such Variable Price Securities, each Holder shall have the right, but not the obligation, in its sole discretion to substitute the Variable Price for the Conversion Price upon conversion of the Series D Preferred Shares by designating in the Conversion Notice delivered upon any conversion of Series D Preferred Shares that solely for purposes of such conversion such Holder is relying on the Variable Price rather than the Conversion Price then in effect. A Holder’s election to rely on a Variable Price for a particular conversion of Series D Preferred Shares shall not obligate such Holder to rely on a Variable Price for any future conversions of Series D Preferred Shares.

Adjustments for Dilutive Issuances. If and whenever the Company grants, issues or sells (or enters into any agreement to grant, issue or sell), or pursuant to the provisions of the Series D Certificate of Designations is deemed to have done any of the foregoing, but excluding any Excluded Securities (as defined in the Series D Certificate of Designations) granted, issued or sold or deemed to have been granted, issued or sold, any shares of Common Stock for a consideration per share (the “New Issuance Price”) less than a price equal to the Conversion Price in effect immediately prior to such granting, issuance or sale (such Conversion Price then in effect is referred to herein as the “Applicable Price”) (the foregoing a “Dilutive Issuance”), then, immediately after such Dilutive Issuance, the Conversion Price then in effect will be reduced to an amount equal to the New Issuance Price.

Voluntary Adjustment Right. Subject to the rules and regulations of the Principal Market, the Company has the right, at any time, with the written consent of the Required Holders, to lower the fixed conversion price to any amount and for any period of time deemed appropriate by the Board.

Change of Control Exchange. Upon a change of control of the Company, each holder may require the Company to exchange the holder’s shares of Series D Preferred Stock for consideration equal to the change of Control Election Price, to be satisfied at the Company’s election in either (x) cash or (y) rights convertible into such securities or other assets to which such holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by such holder upon consummation of such corporate event.

Fundamental Transactions. The Series D Certificate of Designations prohibits the Company from entering specified fundamental transactions (including, without limitation, mergers, business combinations and similar transactions) unless the Company (or the Company’s successor) assumes in writing all of the Company’s obligations under the of Common Stock, except as provided in the transaction documents in the PIPE Financing.

Redemption Rights:

Optional Redemption by the Company. At any time, the Company shall have the right to redeem all, or any part pro rata based on the number of the Preferred Shares then held by the Holders, of the Series D Preferred Shares then outstanding (the “Company Optional Redemption Amount”) on the Company Optional Redemption Date (a “Company Optional Redemption”). The Series D Preferred Shares subject to redemption shall be redeemed by the Company in cash at a price (the “Company Optional Redemption Price”) equal to 25% premium on the greater of (i) the Conversion Amount being redeemed as of the Company Optional Redemption Date and (ii) the product of (1) the Conversion Rate with respect to the Conversion Amount being redeemed as of the Company Optional Redemption Date (as defined in the Series D Certificate of Designations) multiplied by (2) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date immediately preceding such Company Optional Redemption Notice Date (as defined in the Series D Certificate of Designations) and ending on the Trading Day immediately prior to the date the Company makes the entire payment required to be made.

Voting Rights. The holders of the Series D Preferred Stock have no voting power and no right to vote on any matter at any time, either as a separate series or class or together with any other series or class of share of capital stock, and are not entitled to call a meeting of such holders for any purpose nor are they entitled to participate in any meeting of the holders of Common Stock, except as provided in the Series D Certificate of Designations (or as otherwise required by applicable law).

Covenants. The Series D Certificate of Designations contains a variety of obligations on the Company’s part not to engage in specified activities, which are typical for transactions of this type. In particular, the Company will not, and will cause the Company’s subsidiaries to not, redeem, repurchase or declare any dividend or distribution on any of its capital stock (other than as required under the Series D Certificate of Designations). In addition, the Company will not issue any preferred stock or issue any other securities that would cause a breach or default under the Certificate of Designations or Series D Warrants.

Ownership Limitation. In no event may any Series D Preferred Shares be converted (or Series D Warrants be exercised) and shares of Common Stock be issued to any holder if after giving effect to the issuance of shares of Common Stock upon such conversion of the Series D Preferred Shares (or exercise of the Series D Warrants), the holder (together with its affiliates, if any) would beneficially own more than 4.99% of the outstanding shares of Common Stock, which we refer to herein as the “PIPE Blocker”. The PIPE Blocker may be raised or lowered to any other percentage not in excess of 9.99% at the option of the applicable holder of the Series D Preferred Shares (or Series D Warrants), except that any raise will only be effective upon 61-days’ prior notice to the Company.

Exchange Right. If the Company or any of its Subsidiaries consummates any Subsequent Placement (as defined in the Series D Securities Purchase Agreement) (other than with respect to Excluded Securities), and a holder elects in writing to the Company to participate in such Subsequent Placement, each such holder may, at the option of such holder as elected in writing to the Company, exchange all, or any part, of the Series D Preferred Shares of such holder into the securities in such Subsequent Placement (with the aggregate amount of such securities to be issued in such exchange equal to such aggregate amount of such securities with a purchase price valued at a 20% premium on the Conversion Amount of the Series D Preferred Shares delivered by such holder in exchange therefor); provided that any such exchange will be subject to all applicable Nasdaq restrictions.

Reservation Requirements. So long as any Series D Preferred Stock remains outstanding, the Company will at all times reserve at least 150% of the number of shares of Common Stock as will from time to time be necessary to effect the conversion of all Series D Preferred Shares then outstanding.

Conditions Precedent to Closing: As set forth in the Series D Securities Purchase Agreement, the obligations of each party to consummate the PIPE Financing are conditioned upon, among other things, customary closing conditions.

Exercise Price. The initial exercise price of the Series D Warrants is $3.6896. The exercise price is subject to adjustment for stock splits, combinations and similar events, and, in the event of stock dividends and splits, the number of shares of Common Stock issuable upon the exercise of the Series D Warrant also will be adjusted so that the aggregate exercise price will be the same immediately before and immediately after any such adjustment.

Exercise Price Adjustments. If on an Adjustment Date (as defined in the Series D Warrants), the exercise price then in effect is greater than the Market Price then in effect (the “Warrant Adjustment Price”), the exercise price will automatically lower to the Warrant Adjustment Price. As used herein, “Market Price” means, with respect to any Adjustment Date, the greater of (x) the Floor Price and (y) the lowest closing price of the Common Stock on the Principal Market on any Trading Day during the five (5) Trading Day period ended on, and including, the Trading Day ended immediately prior to such applicable Adjustment Date (each, a “Market Price Measuring Period”). All such determinations to be appropriately adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction that proportionately decreases or increases the Common Stock during such applicable Market Price Measuring Period. Only downward adjustments will be made.

Adjustments for Dilutive Issuances or Variable Price Securities. If and whenever the Company grants, issues or sells (or enters into any agreement to grant, issue or sell), or pursuant to the provisions of the Warrant is deemed to have done any of the foregoing, but excluding any Excluded Securities granted, issued or sold or deemed to have been granted, issued or sold any shares of Common Stock for a consideration price per share (the “Warrant New Issuance Price”) less than a price equal to the exercise price in effect immediately prior to such granting, issuance or sale (the foregoing a “Warrant Dilutive Issuance”), then, immediately after such Warrant Dilutive Issuance, the exercise price then in effect will be reduced to an amount equal to the Warrant New Issuance Price. Notwithstanding the foregoing, prior to receipt of applicable stockholder approval, no such adjustments shall cause the exercise price to be less than the floor price of $3.6896.

Additionally, if the Company grants, issues or sells (or enters into any agreement to grant, issue or sell) securities at a Variable Price (as defined in the Series D Warrants), the warrant holder shall have the right, but not the obligation, in its sole discretion to exercise the Series D Warrants at the Variable Price. Notwithstanding the foregoing, prior to receipt of applicable stockholder approval, no such adjustments shall cause the exercise price to be less than the floor price of $3.6896.

Exercise Period. The Series D Warrants are exercisable beginning on the issuance date and expiring on the third anniversary of the issuance date. The Series D Warrants require “buy-in” payments to be made by us for failure to deliver any shares of Common Stock issuable upon exercise.

Cashless Exercise. If at the time of exercise of the Series D Warrants on or after six months and one day from issuance, there is no effective registration statement registering the shares of the Common Stock underlying the Series D Warrants, such Series D Warrants may be exercised on a cashless basis pursuant to their terms.

Purchase Rights; Participation Rights. If the Company issues options, convertible securities, warrants, shares, or similar securities to holders of the Company shares of the Company Common Stock, each Series D Warrant holder has the right to acquire the same as if the holder had exercised its Series D Warrant. The holders of the Series D Warrants are entitled to receive any dividends paid or distributions made to the holders of the Company’s shares of Common Stock on an “as if converted” basis.

Fundamental Transactions. The Series D Warrants prohibit the Company from entering into specified fundamental transactions unless the successor entity assumes all of the Company obligations under the Series D Warrants under a written agreement before the transaction is completed. Upon specified corporate events, a Series D Warrant holder will thereafter have the right to receive upon an exercise such shares, securities, cash, assets or any other property whatsoever which the holder would have been entitled to receive upon the happening of the applicable corporate event had the Series D Warrant been exercised immediately prior to the applicable corporate event. When there is a transaction involving specified changes of control, a Series D Warrant holder will have the right to force the Company to repurchase the holder’s Series D Warrant for a purchase price in cash equal to the Black Scholes value, as calculated under the Series D Warrants, of the then unexercised portion of the Warrant.

Series E Preferred Stock

The terms of the Certificate of Designation of Series E Preferred Stock are substantially the same as the terms of the Certificate of Designation of Series D Preferred Stock, except that each Series E Preferred Stock provides for (i) a Conversion Price of $3.8576, a (ii) Conversion Floor Price of $3.8576 and (iii) a Floor Price of $0.7715.

Series E Warrants

The terms of the Series E Warrants are substantially the same as the terms of the Series D Warrants, except that each Series E Warrant provides for a Conversion Price of $3.8576.

Even if a termination fee is not payable in connection with a termination of the Share Exchange Agreement, we will have incurred significant fees and expenses, which must be paid whether or not the Realbotix Transactions is completed. Further, if the Realbotix Transactions is not completed, it could significantly harm the market price of our common stock.

In addition, if the Share Exchange Agreement is terminated and we determine to seek another business combination, there can be no assurance that we will be able to find a partner and close an alternative transaction on terms that are as favorable as or more favorable to us than the terms set forth in the Share Exchange Agreement.

The closing of the Realbotix Transactions is subject to approval by our stockholders. Failure to obtain these other required approvals would prevent the closing of the Realbotix Transactions.

The closing of the Realbotix Transactions is subject to certain approvals by our stockholders. Failure to obtain the required stockholder approvals may result in a material delay in, or the abandonment of, the Realbotix Transactions. Any delay in completing the Realbotix Transactions may materially adversely affect the timing and benefits that are expected to be achieved from the Realbotix Transactions.

If the Realbotix Transactions is not completed, the Board may decide to pursue our dissolution and liquidation. In such an event, the amount of cash available for distribution to our stockholders will depend heavily on the timing of such liquidation as well as the amount of cash that will need to be reserved for commitments and contingent liabilities.

There can be no assurance that the Realbotix Transactions will be completed. If the Realbotix Transactions is not completed, our Board may decide to pursue our dissolution and liquidation. In such an event, the amount of cash available for distribution to our stockholders will depend heavily on the timing of such decision, as with the passage of time the amount of cash available for distribution will be reduced we continue to fund our operations. In addition, if our Board were to approve and recommend, and our stockholders were to approve, our dissolution and liquidation, we would be required under Delaware corporate law to pay its outstanding obligations, as well as to make reasonable provision for contingent and unknown obligations, prior to making any distributions in liquidation to our stockholders. As a result of this requirement, a portion of our remaining cash assets may need to be reserved pending the resolution of such obligations. In addition, we may be subject to litigation or other claims related to a dissolution and liquidation. If a dissolution and liquidation were pursued, our Board, in consultation with its advisors, would need to evaluate these matters and make a determination about a reasonable amount to reserve. Accordingly, holders of our common stock could lose all or a significant portion of their investment in the event of pir liquidation, dissolution or winding up.

The issuance of securities would result in significant dilution in the equity interest of existing stockholders and adversely affect the marketplace of our Common Stock.

The issuance or conversion of Common Stock or other securities convertible into Realbotix Common Stock in connection with the Realbotix Transactions would result in significant dilution in the equity interest of our existing stockholders and adversely affect the market price of our Common Stock. In addition, future issuances of, or conversions of, securities may result in significant dilution to our existing stockholders, which could adversely impact your investment.

Our stockholders may not realize a benefit from the acquisition of Realbotix commensurate with the ownership dilution they will experience in connection with the Realbotix Transactions contemplated by the Share Exchange Agreement.

If we are unable to realize the full strategic and financial benefits currently anticipated from the Realbotix Transactions, our stockholders may experience a dilution of their ownership interests without receiving any commensurate benefit, or only receiving part of the commensurate benefit to the extent we are able to realize only part of the strategic and financial benefits currently anticipated from the Realbotix Transactions. The Realbotix Transactions may pose integration challenges which could result in management and business disruptions, any of which could harm our results of operation, business prospects, and impair the value of the Realbotix Transactions to our stockholders.

The failure to successfully integrate the businesses of us and Realbotix in the expected timeframe would adversely affect our future results.

Our ability to successfully integrate our operations and those of Realbotix will depend, in part, on our ability to realize the anticipated benefits from the Realbotix Transactions. If we are not able to achieve the stated objectives, the anticipated benefits of the Realbotix Transactions may not be realized fully, or at all, or may take longer to realize than expected, and the value of our Common Stock may be adversely affected. In addition, the integration of our and Realbotix’s respective businesses will be a time-consuming and expensive process. Proper planning and effective and timely implementation will be critical to avoid any significant disruption to our operations. It is possible that the integration process could result in the loss of key employees, the disruption of our business or the identification of inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with customers, suppliers, distributors, creditors or lessors, or to achieve the anticipated benefits of the Realbotix Transactions. Delays encountered in the integration process could have a material adverse effect on our operating results and financial condition, including the value of our Common Stock.

The pending Realbotix Transactions may divert the attention of our management.

The pending Realbotix Transactions could cause the attention of our management to be diverted from the day-to-day operations. These disruptions could be exacerbated by a delay in the completion of the Realbotix Transactions and could have an adverse effect on our business, operating results or prospects regardless of whether the Realbotix Transactions are ultimately completed.

Unexpected market disruptions may cause major losses for us not anticipated under the Share Exchange Agreement.

We may incur major losses in the event of disrupted markets and other extraordinary events in which market behavior diverges significantly from historically recognized patterns, which may offset any potential benefits achieved under the Share Exchange Agreement. The risk of loss in such events may be compounded by the fact that, in disrupted markets, many positions become illiquid, making it difficult or impossible to close out positions against which markets are moving. Market disruptions caused by unexpected political, military and terrorist events, or other factors, may from time to time cause dramatic losses for us.

Risks associated with changes in the technology industry.

Realbotix operates in a competitive industry characterized by rapid technological change and evolving industry standards. Realbotix’s ability to attract new customers to its business, and generate revenue from existing customers will depend largely on its ability to anticipate industry standards and trends, respond to technological advances in its industry, and keep pace with technological developments and customers’ increasingly sophisticated needs. The success of any enhancement of Realbotix’s products or new related applications will depend on several factors, including the timely completion and market acceptance of the products.

Realbotix’s services are expected to embody complex technology that may not meet those standards, changes and preferences. Realbotix’s ability to design, develop and commercially launch products depends on a number of factors, including, but not limited to, its ability to design and implement solutions and services at an acceptable cost and quality, its ability to attract and retain skilled technical employees, the availability of critical components from third parties, and its ability to successfully complete the development of the products in a timely manner. There is no guarantee that Realbotix will be able to respond to market demands. If Realbotix is unable to effectively respond to technological changes or fails or delays to develop services in a timely and cost-effective manner, Realbotix may be unable to recover our development expenses which could negatively impact sales, profitability and the continued viability of its business.

We may be unable to protect Realbotix’s intellectual property.

Realbotix’s commercial success depends to a significant degree upon its ability to develop new or improved technologies, instruments, and services, and to obtain patents, where appropriate, or other intellectual property rights or statutory protection for these technologies and products in Canada and the United States. Despite devoting resources to the research and development of proprietary technology, Realbotix, may not be able to develop new technology that is patentable or protectable. Further, patents issued to Realbotix, if any, could be challenged, held invalid or unenforceable, or be circumvented and may not provide Realbotix with necessary or sufficient protection or a competitive advantage. Competitors and other third parties may be able to design around Realbotix’s intellectual property or develop technology similar to Realbotix’s products that is not within the scope of such intellectual property. Realbotix’s inability to secure its indirectly owned, intellectual property rights may have a materially adverse effect on its business and results of operations.

The business of Realbotix is exposed to cybersecurity risks.

Cyber incidents can result from deliberate attacks or unintentional events, and may arise from internal sources (e.g., employees, contractors, suppliers and operational risks) or external sources (e.g., nation states, terrorists, hacktivists, competitors and acts of nature). Cyber incidents include unauthorized access to information systems and data (e.g., through hacking or malicious software) for purposes of misappropriating or corrupting data or causing operational disruption. Cyber incidents also may be caused in a manner that does not require unauthorized access, such as causing denial-of-service attacks on websites (e.g., efforts to make network services unavailable to intended users). A cyber incident that affects Realbotix might cause disruptions and adversely affect their respective business operations and might also result in violations of applicable law (e.g., personal information protection laws), each of which might result in potentially significant financial losses and liabilities, regulatory fines and penalties, reputational harm, and reimbursement and other compensation costs to Realbotix. In addition, substantial costs might be incurred to investigate, remediate, and prevent cyber incidents.

We expect to incur significant transaction costs in connection with the Realbotix Transactions.

We expect to incur a number of non-recurring costs associated with negotiating and completing the Realbotix Transaction. These fees and costs have been, and will continue to be, substantial and, in many cases, will be borne by us whether or not the Realbotix Transaction is completed. A substantial majority of our non-recurring expenses will consist of transaction costs related to the Realbotix Transactions and include, among others, fees paid to financial, legal, accounting and other advisors. We will continue to assess the magnitude of theses costs, and we may incur additional unanticipated costs. The costs described above and any unanticipated costs and expenses, many of which will be borne by us even if the Realbotix Transaction is not completed, could have an adverse effect on our financial condition and operating results.

ELOC Financing

On October 2, 2024, the Company entered into a Common Stock ELOC Purchase Agreement relating to a Committed Equity Facility with Keystone, whereby the Company may offer and sell, from time to time at its sole discretion, and whereby Keystone has committed to purchase, up to $25.0 million of the Company’s newly issued Common Stock, subject to the limitations described below. Concurrently with entering into the ELOC Purchase Agreement, the Company also entered into a registration rights agreement with Keystone, pursuant to which it agreed to provide Keystone with certain registration rights related to the shares issued under the ELOC Purchase Agreement.

The Company may, from time to time and at its sole discretion, direct Keystone to purchase shares of Common Stock upon the satisfaction of certain conditions set forth in the Common Stock Purchase Agreement at a purchase price per share based on the market price of Common Stock at the time of sale as computed under the ELOC Purchase Agreement. There is no upper limit on the price per share that Keystone could be obligated to pay for Common Stock under the ELOC Purchase Agreement. The Company will control the timing and amount of any sales of Common Stock to Keystone, and Keystone has no right to require the Company to sell any shares to it under the ELOC Purchase Agreement.

The Company does not have a right to commence any sales of Common Stock to the Purchaser under the ELOC Purchase Agreement until the time when all of the conditions to the Company’s right to commence sales of Common Stock to the Purchaser set forth in the ELOC Purchase Agreement have been satisfied, including that a registration statement covering the resale of such shares is declared effective by the SEC and the final form of prospectus is filed with the SEC (the “Commencement Date”). Over the 36-month period from and after the Commencement Date, the Company will control the timing and amount of any sales of Common Stock to the Purchaser. Actual sales of shares of Common Stock to the Purchaser under the ELOC Purchase Agreement will depend on a variety of factors to be determined by the Company from time to time, including, among others, market conditions, the trading price of the Common Stock and determinations by us as to the appropriate sources of funding and the Company’s operations.

Although the Purchase Agreement provides that we may sell up to an aggregate of $25.0 million of our shares of our Common Stock to Keystone, only 25,000,000 shares of our Common Stock (assuming the shares are sold at a price of $0.6771 per share) are being registered for resale under the registration statement that includes this prospectus, in addition to 701,933 split-adjusted shares already issued and sold under the ELOC Purchase Agreement and resale pursuant to separate prospectuses. If it becomes necessary for us to issue and sell to Keystone under the Purchase Agreement more shares than are being registered for resale under this prospectus in order to receive aggregate gross proceeds equal to $25.0 million under the Purchase Agreement, we must first file with the SEC one or more additional registration statements to register under the Securities Act the resale by Keystone of any such additional shares of our Common Stock we wish to sell from time to time under the Purchase Agreement, which the SEC must declare effective, in each case, before we may elect to sell any additional shares of our Common Stock to Keystone under the Purchase Agreement. Through April 24, 2026, the Company has sold approximately 701,933 split-adjusted shares under the ELOC Purchase Agreement for aggregate proceeds of approximately $8.1 million.

In no event will the Company issue to the Purchaser under the ELOC Purchase Agreement more than 19.99% of the total number of shares of Common Stock outstanding immediately prior to the execution of the Common Stock Purchase Agreement, unless (i) the Company obtains the approval of the issuance of such shares by its stockholders in accordance with the applicable stock exchange rules or (ii) sales of Common Stock are made at a price equal to or in excess of the lower of (A) the closing price immediately preceding the delivery of the applicable notice to the Purchaser and (B) the average of the closing prices of the Common Stock for the five business days immediately preceding the delivery of such notice, such that the sales of such Common Stock to the Purchaser would not count toward the Exchange Cap because they are “at market” under applicable stock exchange rules. On October 11, 2024 the Company obtained stockholder approval to issue shares to Keystone in excess of the Exchange Cap.

In all cases, the Company may not issue or sell any shares of Common Stock to Keystone under the Common Stock Purchase Agreement which, when aggregated with all other shares of Common Stock then beneficially owned by Keystone and its affiliates (as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended, and Rule 13d-3 promulgated thereunder), would result in Keystone beneficially owning more than 4.99% of the outstanding shares of Common Stock (the “ELOC Blocker”).

At any time from and after the Commencement Date, on any business day on which the closing sale price of the Common Stock is equal to or greater than $0.05 (the “Purchase Date”), the Company may direct the Purchaser to purchase a specified number of shares of Common Stock (a “Fixed Purchase”) not to exceed 100,000 shares at a purchase price equal to the lesser of 90% of (i) the daily volume weighted average price (the “VWAP”) of the Common Stock for the five trading days immediately preceding the applicable Purchase Date for such Fixed Purchase and (ii) the lowest sale price of a share of Common Stock on the applicable Purchase Date for such Fixed Purchase during the full trading day on such applicable Purchase Date. In any case, the Purchaser’s commitment in any single Fixed Purchase may not exceed $10,000.

In addition, at any time from and after the Commencement Date, on any business day on which the closing sale price of the Common Stock is equal to or greater than $0.05 and such business day is also the Purchase Date for a Fixed Purchase of an amount of shares of Common Stock not less than the applicable Fixed Purchase Maximum Amount (as defined in the Common Stock Purchase Agreement) (the “VWAP Purchase Date”), the Company may also direct the Purchaser to purchase, on the immediately following business day, an additional number of shares of Common Stock in an amount up to the Maximum VWAP Purchase Amount (as defined in the Common Stock Purchase Agreement) (a “VWAP Purchase”) at a purchase price equal to the lesser of 90% of (i) the closing sale price of the Common Stock on the applicable VWAP Purchase Date and (ii) the VWAP during the period on the applicable VWAP Purchase Date beginning at the opening of trading and ending at the VWAP Purchase Termination Time (as defined in the Purchase Agreement). At any time from and after the Commencement Date, on any business day that is also the VWAP Purchase Date for a VWAP Purchase, the Company may also direct the Purchaser to purchase, on such same business day, an additional number of shares of Common Stock in an amount up to the Maximum Additional VWAP Purchase Amount (as defined in the ELOC Purchase Agreement) (an “Additional VWAP Purchase”) at a purchase price equal to the lesser of 90% of (i) the closing sale price of the Common Stock on the applicable Additional VWAP Purchase Date and (ii) the VWAP during the Additional VWAP Purchase Period (as defined in the Common Stock Purchase Agreement).

The net proceeds under the Purchase Agreement to the Company will depend on the frequency and prices at which the Company sells shares of its Common Stock to Keystone. Pursuant to the ELOC Purchase Agreement, up to 30% of the proceeds from each Fixed Purchase and VWAP Purchase Notice must be used to redeem shares of Series C Preferred Stock.

The ELOC Purchase Agreement contains customary representations, warranties and agreements of the Company and Keystone, limitations and conditions regarding sales of Common Stock, indemnification rights and other obligations of the parties.

There are no restrictions on future financings, rights of first refusal, participation rights, penalties or liquidated damages in the ELOC Purchase Agreement other than a prohibition (with certain limited exceptions) on entering into a dilutive securities transaction during certain periods when the Company is selling Common Stock to Keystone under the Purchase Agreement. Keystone has agreed that, during the term of the Purchase Agreement, it will not engage in or effect, directly or indirectly, any short sales involving the Company’s securities or any hedging transaction that transfers the economic risk of ownership of the Common Stock.

The Purchase Agreement will automatically terminate on the earliest to occur of (i) the 36-month anniversary of the effective date of the resale registration statement in connection with the ELOC Purchase Agreement first declared effective by the SEC, or December 12, 2027, (ii) the date on which Keystone will have purchased from the Company under the ELOC Purchase Agreement an aggregate limit of shares of Common Stock as defined therein, (iii) the date on which the Common Stock will have failed to be listed or quoted on Nasdaq or another U.S. national securities exchange identified as an “eligible market” in the ELOC Purchase Agreement, (iv) the 30th trading day after the date on which a voluntary or involuntary bankruptcy proceeding involving the Company has been commenced that is not discharged or dismissed prior to such trading day, and (v) the date on which a bankruptcy custodian is appointed for all or substantially all of the Company’s property or the Company makes a general assignment for the benefit of creditors. The Company has the right to terminate the ELOC Purchase Agreement at any time after the Commencement Date (as defined in the ELOC Purchase Agreement), at no cost or penalty, upon one trading day’s prior written notice to Keystone. Keystone has the right to terminate the Purchase Agreement upon ten trading days’ prior written notice to the Company if certain specified events occur. The Company and Keystone may also agree to terminate the ELOC Purchase Agreement by mutual written consent. Neither the Company nor Keystone may assign or transfer the Company’s respective rights and obligations under the ELOC Purchase Agreement.

Concurrent with the execution of the ELOC Purchase Agreement, the Company entered into a registration rights agreement with Keystone (the “ELOC Registration Rights Agreement”), pursuant to which the Company agreed to file a registration statement covering the issuance and sale of the maximum number of shares issuable under the ELOC Purchase Agreement as may be permitted under applicable rules. The Company agreed to use its commercially reasonable efforts to cause the registration statement to be filed within 45 days after the closing of the ELOC Purchase Agreement and to have such registration statement effective within 120 days of such closing (or 90 days of such closing if the Company is notified by the Securities and Exchange Commission that such registration statement will not be reviewed or subject to further review).

Effect of Sales of our Common Stock under the ELOC Purchase Agreements on our Stockholders

The Common Stock being registered for resale in this offering may be issued and sold by us to the Selling Stockholder from time to time at our discretion, during the terms described above. The resale by the Selling Stockholder of a significant quantity of shares registered for resale in this offering at any given time, or the perception that these sales may occur, could cause the market price of our Common Stock to decline and to be highly volatile. Sales of our Common Stock, if any, to Keystone under the ELOC Purchase Agreement will be determined by us in our sole discretion, subject to the satisfaction of certain conditions in the ELOC Purchase Agreement and will depend upon market conditions and other factors. We may ultimately decide to sell to Keystone all, some or none of the Common Stock that may be available for us to sell to Keystone pursuant to the ELOC Purchase Agreement. If we elect to sell Common Stock to Keystone pursuant to the ELOC Purchase Agreement, after Keystone has acquired such shares, Keystone may resell all, some or none of such Common Stock at any time or from time to time in its discretion and at different prices. As a result, investors who purchase Common Stock from Keystone in this offering at different times will likely pay different prices for those shares of Common Stock, and so may experience different levels of dilution and in some cases substantial dilution and different outcomes in their investment results. See “Risk Factors—Risks Related to the Committed Equity Financings—Investors who buy shares of Common Stock from Keystone at different times will likely pay different prices.”

Investors may experience a decline in the value of the Common Stock they purchase from Keystone in this offering as a result of future sales made by us to Keystone at prices lower than the prices such investors paid for their shares in this offering. In addition, if we sell a substantial number of shares of Common Stock to Keystone under the Keystone ELOC Purchase Agreement, or if investors expect that we will do so, the actual sales of Common Stock or the mere existence of our arrangement with Keystone may make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect such sales.

Because the purchase price per share to be paid by Keystone for the Common Stock that we may elect to sell to Keystone under the ELOC Purchase Agreement, if any, will fluctuate based on the market prices of our Common Stock at the time we make such election, as of the date of this prospectus, it is not possible for us to predict the number of shares of Common Stock that we will sell to Keystone under the ELOC Purchase Agreement, the actual purchase price per share to be paid by Keystone for those shares of Common Stock, or the actual gross proceeds to be raised by us from those sales, if any. As of April 24, 2026, there were 11,464,572 shares of Common Stock outstanding. If all of the 25,000,000 shares of our Common Stock offered for resale by the Selling Stockholders under this prospectus were issued and outstanding as of April 24, 2026, such shares would represent approximately 68.8% of the total number of shares of our Common Stock outstanding. The actual number of shares of our Common Stock issuable will vary depending on the then current market price of shares of our Common Stock sold to the Selling Stockholder in this offering.

The number of shares of Common Stock ultimately offered for sale by the Selling Stockholder for resale under this prospectus is dependent upon the number of shares of Common Stock, if any, we ultimately sell to Keystone under the ELOC Purchase Agreement. Further, if and when we elect to sell shares of Common Stock to Keystone pursuant to the ELOC Purchase Agreement, after Keystone has acquired such shares, Keystone may resell all, some or none of such shares of Common Stock at any time or from time to time in its discretion and at different prices.

The issuance of our shares of Common Stock to the Selling Stockholder pursuant to the ELOC Purchase Agreement will not affect the rights or privileges of our existing stockholders, except that the economic and voting interests of each of our existing stockholders will be diluted. Although the number of shares of Common Stock that our existing stockholders own will not decrease, the shares of Common Stock owned by our existing stockholders will represent a smaller percentage of our total outstanding shares of Common Stock after any such issuance.

Although the ELOC Purchase Agreement provides that we may sell up to an aggregate of $25.0 million of shares of our Common Stock to Keystone, only 25,000,000 shares (assuming the shares are sold at a price of $0.6771 per share) are being registered for resale under the registration statement that includes this prospectus. If it becomes necessary for us to issue and sell more shares than are being registered for resale under this prospectus in order to receive aggregate gross proceeds equal to $25.0 million under the ELOC Purchase Agreement, we must first file with the SEC one or more additional registration statements to register under the Securities Act the resale by Keystone of any such additional shares of our Common Stock we wish to sell from time to time under the ELOC Purchase Agreement, which the SEC must declare effective, in each case, before we may elect to sell any additional shares of our Common Stock to Keystone under the ELOC Purchase Agreement.

The following table sets forth the number of shares of Common Stock to be issued to Keystone under the ELOC Purchase Agreement registered hereunder at varying purchase prices:

Assumed Average Purchase Price Per Share		Number of Registered Shares to be Issued if Full Purchase⁽¹⁾		Percentage of Outstanding Shares After Giving Effect to the Issuance to Keystone⁽²⁾			Gross Proceeds from the Sale of Shares to Keystone Under the Purchase Agreement
$	0.50		33,858,886		74.9	%	$	16,929,443
$	1.00		16,929,443		59.9	%	$	16,929,443
$	1.50		11,286,295		49.9	%	$	16,929,443

Notes to table:

(1)	The purchase prices assume a discount to the market prices of our shares, in accordance with the ELOC Purchase Agreement.

(2)

The denominator is based on 11,464,572 shares outstanding as of April 24, 2026, adjusted to include the number of shares set forth in the adjacent column that we would have sold to Keystone, assuming the average purchase price in the first column. The numerator is based on the number of shares issuable pursuant to future sales under the ELOC Purchase Agreement (that are the subject of this offering) at the corresponding assumed average purchase price set forth in the first column.

Pursuant to the ELOC Purchase Agreement, 30% of the gross proceeds to the Company from any sale of Common Stock thereunder must be applied towards the redemption of the Company’s Series C Preferred Stock.

Any remaining proceeds we receive from the sale of Common Stock under the ELOC Purchase Agreement will be used for general corporate and working capital or for other purposes that the Board, in its good faith, deems to be in the best interest of the Company. Through April 24, 2026, the Company has sold approximately 701,933 split-adjusted shares under the ELOC Purchase Agreement for aggregate proceeds of approximately $8.1 million. No assurances can be given that we will receive any further proceeds from sale of Common Stock under the ELOC Purchase Agreement.

DETERMINATION OF OFFERING PRICE

The Selling ~~Stockholders will~~Stockholder will offer Common Stock at the prevailing market prices or a privately negotiated price as it may determine from time to time.

The offering price of our Common Stock to be sold by the Selling ~~Stockholders~~Stockholder does not necessarily bear any relationship to our book value, assets, past operating results, financial condition, or any other established criteria of value. The facts considered in determining the offering price were our financial condition and prospects, our limited operating history and the general condition of the securities market.

In addition, there is no assurance that our Common Stock will trade at market prices in excess of the offering price as prices for our Common Stock in any public market will be determined in the marketplace and may be influenced by many factors, including the depth and liquidity.

The Company has issued 3,499 shares of the Company Series C Preferred Stock to the PIPE Investors.

Ranking. Except (i) for the Series A Preferred Stock of the Company (of which there are no shares currently outstanding), which shall be Parity Stock, and (ii) to the extent that the Required Holders (as defined in the Securities Purchase Agreement) expressly consent to the creation of Parity Stock or Senior Preferred Stock, all shares of capital stock of the Company will be junior in rank to all Series D Preferred Shares with respect to the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding up of the Company.

Dividends. The holders of Series C Preferred Stock are entitled to dividends, on an as-if converted basis, equal to and in the same form as dividends actually paid on shares of Common Stock, when and if actually paid. In addition, from and after the occurrence and during the continuance of any Triggering Event, dividends (“Default Dividends”) will accrue on the Stated Value of each Series D Preferred Share at a rate of fifteen percent (15.0%) (the “Default Rate”) per annum. Default Dividends are payable by way of inclusion of Default Dividends in the Conversion Amount (as defined below) on each Conversion Date, upon any redemption or upon any required payment upon any Bankruptcy Triggering Event. In the event that such Triggering Event is subsequently cured (and no other Triggering Event then exists), the accrual of Default Dividends will cease to be effective as of the calendar day immediately following the date of such cure; provided that Default Dividends as calculated and unpaid during the continuance of such Triggering Event will continue to apply to the extent relating to the days after the occurrence of such Triggering Event through and including the date of such cure of such Triggering Event.

Conversion Price Adjustments. If on the ninetieth (90th) calendar day and one hundred eightieth (180) calendar day (each an “Adjustment Date”) following the occurrence of the later of (x) the date that Company stockholders approve the transaction and all securities issuable to the Series C PIPE Investors in connection therewith, as required by Nasdaq (“Stockholder Approval”) and (y) the earlier of (a) the effective date of the registration statement to be filed pursuant to the Registration Rights Agreement and (b) the date that the Series C Preferred Stock is eligible to be resold without restriction under Rule 144 of the Securities Act, as amended (the “Securities Act”), the Conversion Price then in effect is greater than the Market Price then in effect (the “Adjustment Price”), the Conversion Price will automatically lower to the Adjustment Price. As used herein, “Market Price” means, with respect to any Adjustment Date, the greater of (x) the Floor Price and (y) the lowest closing price of the Common Stock on the Principal Market on any Trading Day during the five (5) Trading Day period ended on, and including, the Trading Day ended immediately prior to such applicable Adjustment Date (each, a “Market Price Measuring Period”).

Only downward adjustments will be made.

Share Combination Event Adjustment. In addition to the adjustments set forth above, if at any time and from time to time on or after Stockholder Approval, there occurs any share split, share dividend, share combination recapitalization or other similar transaction involving the Common Stock (each, a “Share Combination Event”, and such date thereof, the “Share Combination Event Date”) and the lowest VWAP during the ten consecutive (10) Trading Day period ending and including the fifth (5) Trading Day immediately preceding the Share Combination Event Date (the “Event Market Price”) (provided if the Share Combination Event is effective after close of trading on the primary Trading Market, then commencing on the next Trading Day which period will be the “Share Combination Adjustment Period”) is less than the Conversion Price then in effect, then at the close of trading on the primary Trading Market on the last day of the Share Combination Adjustment Period, the Conversion Price then in effect on such fifth (5th) Trading Day will be reduced (but in no event increased) to the Event Market Price, but not less than the Floor Price. Notwithstanding the foregoing, if one or more Share Combination Events occur prior to Stockholder Approval being obtained and a reduction of the Conversion Price did not occur, once Stockholder Approval is obtained, the Conversion Price will automatically be reduced to equal the lowest Event Market Price with respect to any Share Combination Event that occurred prior to Stockholder Approval being obtained, but not less than the Floor Price.

Adjustments for Dilutive Issuances or Variable Price Securities. If and whenever the Company grants, issues or sells (or enters into any agreement to grant, issue or sell), or pursuant to the provisions of the Series C Certificate of Designations is deemed to have done any of the foregoing, but excluding any Excluded Securities granted, issued or sold or deemed to have been granted, issued or sold, any shares of Common Stock for a consideration price per share (the “New Issuance Price”) less than a price equal to the Conversion Price in effect immediately prior to such granting, issuance or sale (such Conversion Price then in effect is referred to herein as the “Applicable Price”) (the foregoing a “Dilutive Issuance”), then, immediately after such Dilutive Issuance, the Conversion Price then in effect will be reduced to an amount equal to the New Issuance Price.

Additionally, if the Company grants, issues or sells (or enters into any agreement to grant, issue or sell) securities that are issuable pursuant to such agreement or convertible into or exchangeable or exercisable for shares of Common Stock at a price which varies or may vary with the market price of the shares of Common Stock, including by way of one or more reset(s) to a fixed price, (each of the formulations for such variable price being herein referred to as, the “Variable Price”), the holder shall have the right, but not the obligation, in its sole discretion to substitute the Variable Price for the Conversion Price.

Voluntary Adjustment Right. Subject to the rules and regulations of the Principal Market, the Company has the right, at any time, with the written consent of the Required Holders, to lower the fixed conversion price to any amount and for any period of time deemed appropriate by the Company board of directors.

Exercise Price Adjustments. If on an Adjustment Date, the exercise price then in effect is greater than the Market Price then in effect (the “Warrant Adjustment Price”), the exercise price will automatically lower to the Warrant Adjustment Price. As used herein, “Market Price” means, with respect to any Adjustment Date, the greater of (x) the Floor Price and (y) the lowest closing price of the Common Stock on the Principal Market on any Trading Day during the five (5) Trading Day period ended on, and including, the Trading Day ended immediately prior to such applicable Adjustment Date (each, a “Market Price Measuring Period”).

Additionally, if the Company grants, issues or sells (or enters into any agreement to grant, issue or sell) securities at a Variable Price, the warrant holder shall have the right, but not the obligation, in its sole discretion to exercise the Series C Warrants at the Variable Price.

Exercise Period. The Series C Warrants are exercisable beginning six months after the issuance date (the “Initial Exercisability Date”) and expiring on the third anniversary of the Initial Exercisability Date. The Series C Warrants require “buy-in” payments to be made by us for failure to deliver any shares of Common Stock issuable upon exercise.

22Cashless Exercise. If at the time of exercise of the Series C Warrants, there is no effective registration statement registering the shares of the Common Stock underlying the Series C Warrants, such Series C Warrants may be exercised on a cashless basis pursuant to their terms.

After the Stockholder Approval Date (as defined in the Series D Securities Purchase Agreement), if a Triggering Event occurs and is continuing, at any time after the earlier of a holder’s receipt of a Triggering Event Notice (as defined below) and such holder becoming aware of such Triggering Event (such earlier date, the “Alternate Conversion Right Commencement Date”) and ending on the twentieth (20^th) Trading Day (as defined in the Series D Securities Purchase Agreement) after the later of (x) the date such Triggering Event is cured and (y) such holder’s receipt of a Triggering Event Notice (such ending date, the “Alternate Conversion Right Expiration Date”, and each such period, an “Alternate Conversion Right Period”), such holder may, at such holder’s option, by delivery of a Conversion Notice to the Company (the date of any such Conversion Notice, each an “Alternate Conversion Date”), convert all, or any number of Series D Preferred Stock held by such holder into shares of Common Stock at the Alternate Conversion Price (each, an “Alternate Conversion”). Additionally, at any time after the Stockholder Approval Date, the Holder may convert any number of Series D Preferred Stock held by such Holder at the Alternate Optional Conversion Price.

As used herein with respect to the Series D Preferred Stock:

“Alternate Conversion Price” means, with respect to any Alternate Conversion that price which will be the lowest of (i) the applicable Conversion Price as in effect on the applicable Conversion Date of the applicable Alternate Conversion, and (ii) the greater of (x) the Floor Price (as defined below) and (y) 90% of the lowest VWAP of the Common Stock during the five (5) consecutive Trading Day period ending and including the Trading Day immediately preceding the delivery or deemed delivery of the applicable Conversion Notice (such period, the “Alternate Conversion Measuring Period”). All such determinations to be appropriately adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction that proportionately decreases or increases the Common Stock during such Alternate Conversion Measuring Period.

“Alternate Conversion Floor Amount” means an amount equal to the product obtained by multiplying (A) the higher of (i) the highest price that the Common Stock trades at on the Trading Day immediately preceding the relevant Alternate Conversion Date and (ii) the applicable Alternate Conversion Price and (B) the difference obtained by subtracting (i) the number of shares of Common Stock delivered (or to be delivered) to such holder on the applicable Share Delivery Deadline (as defined in the Series D Certificate of Designations) with respect to such Alternate Conversion from (ii) the quotient obtained by dividing (x) the applicable Conversion Amount that such holder has elected to be the subject of the applicable Alternate Conversion, by (y) the applicable Alternate Conversion Price, without giving effect to the Floor Price.

“Alternate Optional Conversion Price” means, with respect to any Alternate Conversion that price which will be the lowest of (i) the applicable Conversion Price as in effect on the applicable Conversion Date of the applicable Alternate Conversion, and (ii) the greater of (x) the Floor Price and (y) 95% of the lowest VWAP of the Common Stock during the five (5) consecutive Trading Day period ending and including the Trading Day immediately preceding the delivery or deemed delivery of the applicable Conversion Notice (such period, the “Alternate Optional Conversion Measuring Period”). All such determinations to be appropriately adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction that proportionately decreases or increases the Common Stock during such Alternate Optional Conversion Measuring Period.

“Floor Price” means $0.5322 on a post-reverse split and post-adjustment date basis (as adjusted for stock splits, stock dividends, stock combinations, recapitalizations and similar events), or, subject to the rules and regulations of the Principal Market (as defined in the Series D Certificate of Designations), such lower price as the Company and the Required Holders may agree, from time to time.

“Triggering Event Notice” means written notice from the Company delivered to each holder within two Business Days (as defined in the Series D Securities Purchase Agreement) after the occurrence of a Triggering Event) that includes (i) a reasonable description of the applicable Triggering Event, (ii) a certification as to whether, in the reasonable opinion of the Company, such Triggering Event is capable of being cured and, if applicable, a reasonable description of any existing plans of the Company to cure such Triggering Event and (iii) a certification as to the date the Triggering Event occurred and, if cured on or prior to the date of such Triggering Event Notice, the applicable Alternate Conversion Right Expiration Date.

“Triggering Event” includes, but is not limited to, the following, subject to certain cure periods as set forth in the Series D Certificate of Designations:

(i) the failure to file a registration statement for the resale of the shares of Common Stock underlying the Series D Preferred Stock and the Warrants, or the failure of the applicable registration statement to be declared effective by the SEC, ten (10) days after the applicable deadline;

(ii) the failure to maintain the effectiveness of a registration statement pursuant to the terms of the Registration Rights Agreement;

(iii) the suspension from trading or the failure of the Common Stock to be trading or listed (as applicable) on an Eligible Market for a period of five (5) consecutive Trading Days;

(iv) failure to cure a Conversion Failure or a Delivery Failure (as defined in the Warrants) by delivery of the required number of shares of Common Stock within the requisite time frame;

(v) failure to maintain authorized, but unissued shares equal to 150% of the shares underlying the Series D Preferred Stock and the Warrants;

(xv) any breach or failure in any respect by the Company or any Subsidiary to comply with any provision of the covenants listed in the Series D Certificate of Designations;

(xvi) any Series D Preferred Stock remain outstanding on or after March 23, 2027;

(xvii) any Change of Control occurs without the prior written consent of the Required Holders, which consent will not be unreasonably withheld, conditioned or delayed;

(xviii) any Material Adverse Effect occurs; or

Stock Combination Event Adjustment. In addition to the adjustments set forth above, if at any time and from time to time on or after Stockholder Approval, there occurs any share split, share dividend, stock combination recapitalization or other similar transaction involving the Common Stock (each, a “Stock Combination Event”, and such date thereof, the “Stock Combination Event Date”) and the lowest VWAP during the ten consecutive (10) Trading Day period ending and including the fifth (5) Trading Day immediately preceding the Stock Combination Event Date (the “Event Market Price”) (provided if the Stock Combination Event is effective after close of trading on the primary Trading Market, then commencing on the next Trading Day which period will be the “Stock Combination Adjustment Period”) is less than the Conversion Price then in effect, then at the close of trading on the primary Trading Market on the last day of the Stock Combination Adjustment Period, the Conversion Price then in effect on such fifth (5th) Trading Day will be reduced (but in no event increased) to the Event Market Price, but not less than the Floor Price. Notwithstanding the foregoing, if one or more Stock Combination Events occur prior to Stockholder Approval being obtained and a reduction of the Conversion Price did not occur, once Stockholder Approval is obtained, the Conversion Price will automatically be reduced to equal the lowest Event Market Price with respect to any Stock Combination Event that occurred prior to Stockholder Approval being obtained, but not less than the Floor Price.

Adjustments for Variable Price Security Issuances. If the Company in any manner issues or sells or enters into any agreement to issue or sell, any Common Stock, Options or Convertible Securities (other than with respect to a Permitted Equity Line (as defined in the Series D Securities Purchase Agreement)) (any such securities, “Variable Price Securities”) after the Subscription Date (as defined in the Series D Certificate of Designations) that are issuable pursuant to such agreement or convertible into or exchangeable or exercisable for shares of Common Stock at a price which varies or may vary with the market price of the shares of Common Stock, including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting share splits, share combinations and share dividends (each of the formulations for such variable price being herein referred to as, the “Variable Price”), the Company shall provide written notice thereof via electronic mail and overnight courier to each Holder on the date of such agreement and/or the issuance of such shares of Common Stock, Convertible Securities or Options, as applicable. From and after the date the Company enters into such agreement or issues any such Variable Price Securities, each Holder shall have the right, but not the obligation, in its sole discretion to substitute the Variable Price for the Conversion Price upon conversion of the Series D Preferred Stock by designating in the Conversion Notice delivered upon any conversion of Series D Preferred Stock that solely for purposes of such conversion such Holder is relying on the Variable Price rather than the Conversion Price then in effect. A Holder’s election to rely on a Variable Price for a particular conversion of Series D Preferred Stock shall not obligate such Holder to rely on a Variable Price for any future conversions of Series D Preferred Stock.

Adjustments for Dilutive Issuances. If and whenever the Company grants, issues or sells (or enters into any agreement to grant, issue or sell), or pursuant to the provisions of the Series D Certificate of Designations is deemed to have done any of the foregoing, but excluding any Excluded Securities (as defined in the Series D Certificate of Designations) granted, issued or sold or deemed to have been granted, issued or sold, any shares of Common Stock for a consideration per share (the “New Issuance Price”) less than a price equal to the Conversion Price in effect immediately prior to such granting, issuance or sale (such Conversion Price then in effect is referred to herein as the “Applicable Price”) (the foregoing a “Dilutive Issuance”), then, immediately after such Dilutive Issuance, the Conversion Price then in effect will be reduced to an amount equal to the New Issuance Price.

Voluntary Adjustment Right. Subject to the rules and regulations of the Principal Market, the Company has the right, at any time, with the written consent of the Required Holders, to lower the fixed conversion price to any amount and for any period of time deemed appropriate by the Board.

Change of Control Exchange. Upon a change of control of the Company, each holder may require the Company to exchange the holder’s shares of Series D Preferred Stock for consideration equal to the change of Control Election Price, to be satisfied at the Company’s election in either (x) cash or (y) rights convertible into such securities or other assets to which such holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by such holder upon consummation of such corporate event.

Fundamental Transactions. The Series D Certificate of Designations prohibits the Company from entering specified fundamental transactions (including, without limitation, mergers, business combinations and similar transactions) unless the Company (or the Company’s successor) assumes in writing all of the Company’s obligations under the of Common Stock, except as provided in the transaction documents in connection with the Series D Securities Purchase Agreement.

Redemption Rights:

Optional Redemption by the Company. At any time, the Company shall have the right to redeem all, or any part pro rata based on the number of the Preferred Shares then held by the Holders, of the Series D Preferred Stock then outstanding (the “Company Optional Redemption Amount”) on the Company Optional Redemption Date (a “Company Optional Redemption”). The Series D Preferred Stock subject to redemption shall be redeemed by the Company in cash at a price (the “Company Optional Redemption Price”) equal to 25% premium on the greater of (i) the Conversion Amount being redeemed as of the Company Optional Redemption Date and (ii) the product of (1) the Series D Conversion Rate with respect to the Conversion Amount being redeemed as of the Company Optional Redemption Date (as defined in the Series D Certificate of Designations) multiplied by (2) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date immediately preceding such Company Optional Redemption Notice Date (as defined in the Series D Certificate of Designations) and ending on the Trading Day immediately prior to the date the Company makes the entire payment required to be made.

Voting Rights. The holders of the Series D Preferred Stock have no voting power and no right to vote on any matter at any time, either as a separate series or class or together with any other series or class of share of capital stock, and are not entitled to call a meeting of such holders for any purpose nor are they entitled to participate in any meeting of the holders of Common Stock, except as provided in the Series D Certificate of Designations (or as otherwise required by applicable law).

Covenants. The Series D Certificate of Designations contains a variety of obligations on the Company’s part not to engage in specified activities, which are typical for transactions of this type. In particular, the Company will not, and will cause the Company’s subsidiaries to not, redeem, repurchase or declare any dividend or distribution on any of its capital stock (other than as required under the Series D Certificate of Designations). In addition, the Company will not issue any preferred stock or issue any other securities that would cause a breach or default under the Certificate of Designations or Series D Warrants.

Ownership Limitation. In no event may any Series D Preferred Stock be converted (or Series D Warrants be exercised) and shares of Common Stock be issued to any holder if after giving effect to the issuance of shares of Common Stock upon such conversion of the Series D Preferred Stock (or exercise of the Series D Warrants), the holder (together with its affiliates, if any) would beneficially own more than 4.99% of the outstanding shares of Common Stock, which we refer to herein as the “Series D PIPE Blocker”. The Series D PIPE Blocker may be raised or lowered to any other percentage not in excess of 9.99% at the option of the applicable holder of the Series D Preferred Stock (or Series D Warrants), except that any raise will only be effective upon 61-days’ prior notice to the Company.

Exchange Right. If the Company or any of its Subsidiaries consummates any Subsequent Placement (as defined in the Series D Securities Purchase Agreement) (other than with respect to Excluded Securities), and a holder elects in writing to the Company to participate in such Subsequent Placement, each such holder may, at the option of such holder as elected in writing to the Company, exchange all, or any part, of the Series D Preferred Stock of such holder into the securities in such Subsequent Placement (with the aggregate amount of such securities to be issued in such exchange equal to such aggregate amount of such securities with a purchase price valued at a 20% premium on the Conversion Amount of the Series D Preferred Stock delivered by such holder in exchange therefor); provided that any such exchange will be subject to all applicable Nasdaq restrictions.

Reservation Requirements. So long as any Series D Preferred Stock remains outstanding, the Company will at all times reserve at least 150% of the number of shares of Common Stock as will from time to time be necessary to effect the conversion of all Series D Preferred Stock then outstanding.

Conditions Precedent to Closing: As set forth in the Series D Securities Purchase Agreement, the obligations of each party to consummate the transactions in connection with the Series D Securities Purchase Agreement are conditioned upon, among other things, customary closing conditions.

Series D Warrants

Exercise Price. The initial exercise price of the Series D Warrants is $18.448 on a post-reverse split basis. The exercise price is subject to adjustment for stock splits, combinations and similar events, and, in the event of stock dividends and splits, the number of shares of Common Stock issuable upon the exercise of the Series D Warrant also will be adjusted so that the aggregate exercise price will be the same immediately before and immediately after any such adjustment.

Exercise Price Adjustments. If on an Adjustment Date (as defined in the Series D Warrants), the exercise price then in effect is greater than the Market Price then in effect (the “Warrant Adjustment Price”), the exercise price will automatically lower to the Warrant Adjustment Price. As used herein, “Market Price” means, with respect to any Adjustment Date, the greater of (x) the Floor Price and (y) the lowest closing price of the Common Stock on the Principal Market on any Trading Day during the five (5) Trading Day period ended on, and including, the Trading Day ended immediately prior to such applicable Adjustment Date (each, a “Market Price Measuring Period”). All such determinations to be appropriately adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction that proportionately decreases or increases the Common Stock during such applicable Market Price Measuring Period. Only downward adjustments will be made.

Adjustments for Dilutive Issuances or Variable Price Securities. If and whenever the Company grants, issues or sells (or enters into any agreement to grant, issue or sell), or pursuant to the provisions of the Series D Warrant is deemed to have done any of the foregoing, but excluding any Excluded Securities granted, issued or sold or deemed to have been granted, issued or sold any shares of Common Stock for a consideration price per share (the “Warrant New Issuance Price”) less than a price equal to the exercise price in effect immediately prior to such granting, issuance or sale (the foregoing a “Warrant Dilutive Issuance”), then, immediately after such Warrant Dilutive Issuance, the exercise price then in effect will be reduced to an amount equal to the Warrant New Issuance Price. Notwithstanding the foregoing, prior to receipt of applicable stockholder approval, no such adjustments shall cause the exercise price to be less than the floor price of $18.448 on a post-reverse split basis. As of December 5, 2025, such stockholder approval had been obtained.

Exercise Period. The Series D Warrants are exercisable beginning on the issuance date and expiring on the third anniversary of the issuance date. The Series D Warrants require “buy-in” payments to be made by us for failure to deliver any shares of Common Stock issuable upon exercise.

Cashless Exercise. If at the time of exercise of the Series D Warrants on or after six months and one day from issuance, there is no effective registration statement registering the shares of the Common Stock underlying the Series D Warrants, such Series D Warrants may be exercised on a cashless basis pursuant to their terms.

Purchase Rights; Participation Rights. If the Company issues options, convertible securities, warrants, shares, or similar securities to holders of the Company shares of the Common Stock, each Series D Warrant holder has the right to acquire the same as if the holder had exercised its Series D Warrant. The holders of the Series D Warrants are entitled to receive any dividends paid or distributions made to the holders of the Company’s shares of Common Stock on an “as if converted” basis.

Fundamental Transactions. The Series D Warrants prohibit the Company from entering into specified fundamental transactions unless the successor entity assumes all of the Company obligations under the Series D Warrants under a written agreement before the transaction is completed. Upon specified corporate events, a Series D Warrant holder will thereafter have the right to receive upon an exercise such shares, securities, cash, assets or any other property whatsoever which the holder would have been entitled to receive upon the happening of the applicable corporate event had the Series D Warrant been exercised immediately prior to the applicable corporate event. When there is a transaction involving specified changes of control, a Series D Warrant holder will have the right to force the Company to repurchase the holder’s Series D Warrant for a purchase price in cash equal to the Black Scholes value, as calculated under the Series D Warrants, of the then unexercised portion of the Series D Warrant.

Series E Preferred Stock

The terms of the Certificate of Designation of Series E Preferred Stock are substantially the same as the terms of the Certificate of Designation of Series D Preferred Stock, except that each Series E Preferred Stock provides for, each at a post-reverse split basis, (i) an initial Conversion Price of $19.288, a (ii) Conversion Floor Price of $19.288 and (iii) a Floor Price of $0.298.

Series E Warrants

The terms of the Series E Warrants are substantially the same as the terms of the Series D Warrants, except that each Series E Warrant provides for an initial exercise price of $19.288 on a post-reverse split basis.

PIOs

The following is a summary of certain terms and provisions of the preferred investment options (“PIOs”), issued on August 2, 2023, to certain institutional investors.

Duration and Exercise Price. Each PIO will have an exercise price equal to $2,554.30 per share on a post-reverse split basis. The PIOs will be exercisable at any time on or after the date upon the stockholders’ approval of the transaction and have a term of exercise of five (5) years following the date of stockholder approval. The exercise price and number of shares of Common Stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, subsequent rights offerings, pro rate distributions, reorganizations, a Fundamental Transaction (as defined in the PIOs) or similar events affecting our common stock and the exercise price.

Exercisability. The PIOs will be exercisable, at the option of each holder, in whole or in part, by delivering to the Company 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 PIOs 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 the Company, the holder may increase the amount of ownership of outstanding stock after exercising the holder’s PIOs up to 9.99% of the number of shares of the Company’s Common Stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the PIOs.

Cashless Exercise. If, at the time a holder exercises its PIOs, a registration statement registering the resale of the Inducement PIO Shares by the holder under the Securities Act is not then effective or available, 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 PIOs.

Trading Market. There is no established trading market for the PIOs, and the Company does not expect an active trading market to develop. The Company does not intend to apply to list the PIOs on any securities exchange or other trading market. Without a trading market, the liquidity of the PIOs will be extremely limited.

Rights as a Stockholder. Except as otherwise provided in the PIOs or by virtue of the holder’s ownership of shares of the Company’s common stock, such holder of PIOs does not have the rights or privileges of a holder of the Company’s common stock, including any voting rights, until such holder exercises such holder’s PIOs. The PIOs will provide that the holders of the PIOs have the right to participate in distributions or dividends paid on the Company’s shares of common stock.

Waivers and Amendments. The PIOs may be modified or amended or the provisions of the PIOs waived with the Company’s and the holder’s written consent.

Anti-Takeover Effects of Delaware Law and Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

Some provisions of Delaware law, our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire us even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price.

These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our Board. We believe that the benefits of the increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

Delaware Anti-Takeover Statute

We are subject to Section 203 of the General Corporation Law of the State of Delaware, which prohibits persons deemed to be “interested stockholders” from engaging in a “business combination” with a publicly held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the Board.

2338

Choice of Forum

Our Amended and Restated Certificate of Incorporation provides that, unless we consent in writing to an alternative forum, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and certain other actions may be brought only in the Court of Chancery in the State of Delaware, except any action (A) as to which the Court of Chancery in the State of Delaware determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), (B) which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery or (C) for which the Court of Chancery does not have subject matter jurisdiction. If an action is brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel. Although we believe this provision benefits us by providing increased consistency in the application of law in the types of lawsuits to which it applies, a court may determine that this provision is unenforceable, and to the extent it is enforceable, the provision may have the effect of discouraging lawsuits against our directors and officers.

Our Amended and Restated Certificate of Incorporation provides that the exclusive forum provision will be applicable to the fullest extent permitted by applicable law, subject to certain exceptions. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. In addition, our Amended and Restated Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act or the rules and regulations promulgated thereunder. We note, however, that there is uncertainty as to whether a court would enforce this provision and that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Section 22 of the Securities Act creates concurrent jurisdiction for state and federal courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

Transfer Agent and Registrar

The transfer agent and registrar for our Common Stock is Continental Stock Transfer & Trust Company. The Transfer Agent’s address is 1 State Street, 30^thFloor, New York, New York 10004.

Listing

Our Common Stock is traded on The Nasdaq Capital Market under the trading symbol “ONCO.”

Elimination of Monetary Liability for Officers and Directors

Our Amended and Restated Certificate of Incorporation incorporates certain provisions permitted under the Delaware General Corporation Law (“DGCL”) relating to the liability of directors. The provisions eliminate a director’s liability for monetary damages for a breach of fiduciary duty, including gross negligence, except in circumstances involving certain wrongful acts, such as the breach of director’s duty of loyalty or acts or omissions, which involve intentional misconduct or a knowing violation of law. These provisions do not eliminate a director’s duty of care. Moreover, these provisions do not apply to claims against a director for certain violations of law, including knowing violations of federal securities law. Our Amended and Restated Certificate of Incorporation also contains provisions to indemnify the directors, officers, employees or other agents to the fullest extent permitted by the DGCL. We believe that these provisions will assist us in attracting and retaining qualified individual to serve as directors.

Indemnification of Officers and Directors

Our Amended and Restated Certificate of Incorporation also contains provisions to indemnify the directors, officers, employees or other agents to the fullest extent permitted by the DGCL. These provisions may have the practical effect in certain cases of eliminating the ability of stockholders to collect monetary damages from directors. We are also a party to indemnification agreements with each of our directors. We believe that these provisions will assist us in attracting or retaining qualified individuals to serve as our directors.

Item 14. Indemnification of Directors and Officers.

Section 145 of the DGCL inter alia, empowers a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Similar indemnity is authorized for such persons against expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of any such threatened, pending or completed action or suit if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and provided further that (unless a court of competent jurisdiction otherwise provides) such person shall not have been adjudged liable to the corporation. Any such indemnification may be made only as authorized in each specific case upon a determination by the stockholders or disinterested directors or by independent legal counsel in a written opinion that indemnification is proper because the indemnitee has met the applicable standard of conduct.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him under Section 145. We maintain policies insuring our officers and directors against certain liabilities for actions taken in such capacities, including liabilities under the Securities Act.

Section 102(b)(7) of the DGCL permits a corporation to include in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payment of dividends and unlawful stock purchase or redemption) or (iv) for any transaction from which the director derived an improper personal benefit.

Article 6 of the bylaws of the Company contains provisions which are designed to provide mandatory indemnification of directors and officers of the Company to the full extent permitted by law, as now in effect or later amended. The bylaws further provide that, if and to the extent required by the DGCL, an advance payment of expenses to a director or officer of the Company that is entitled to indemnification will only be made upon delivery to the Company of an undertaking, by or on behalf of the director or officer, to repay all amounts so advanced if it is ultimately determined that such director is not entitled to indemnification.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1)

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(2)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(3)

That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i)

If the registrant is relying on Rule 430B:

(A)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

(ii)

If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
