NOTES TO FINANCIAL STATEMENTS

(UNAUDITED)

Unless the context otherwise indicates, references in these Notes to the accompanying financial statements to “we,” “us,” “our” and “the Company” refer to Synaptogenix, Inc. (formerly known as Neurotrope Bioscience, Inc.), a Delaware corporation. References to “Neurotrope”, “Parent Company” or “Parent” refer to Neurotrope, Inc., a Nevada corporation.

Note 1 – Organization, Business, Risks and Uncertainties:

Organization and Business

On May 17, 2020, Neurotrope, Inc. (“Neurotrope” or “the Parent”) announced plans for the complete legal and structural separation of its wholly owned subsidiary, Neurotrope Bioscience, Inc., from Neurotrope (the “Spin-Off”). Under the Separation and Distribution Agreement, Neurotrope distributed all of its equity interest in this wholly owned subsidiary to Neurotrope’s stockholders. Following the Spin-Off, Neurotrope does not own any equity interest in the Company, and the Company operates independently from Neurotrope. On December 7, 2020, the Company became an independent company, Synaptogenix, Inc., a Delaware corporation (formerly known as Neurotrope Bioscience, Inc.) (the “Company” or “Synaptogenix”) when the Company filed an amended and restated certificate of incorporation which, among other things, changed its name to Synaptogenix, Inc. The Company’s shares of common stock, par value $0.0001 per share (the “Common Stock”), are listed on The Nasdaq Capital Market under the symbol “SNPX.”

Recent Developments

Exploring Strategic Alternatives

In December 2024, the Company announced via press release that the board of directors of the Company (the “Board”) had formed an independent special committee (the “Special Committee”) to explore strategic opportunities to create and enhance value for investors, including promising drug development platforms and/or compelling new technologies and services. Management has reviewed the Company’s financial position and has concluded that the Company’s continuing financial strength offset by anticipated future burn rate and publicly traded stock as currency allows the Special Committee to have the resources to continue evaluating potential strategic opportunities.

Liquidity Uncertainties

As of March 31, 2025, the Company had approximately $14.8 million in cash and cash equivalents as compared to$17.7 million at December 31, 2024. The Company expects that its current cash and cash equivalents, approximately $13.8 million as of the date of this Quarterly Report on Form 10-Q, will be sufficient to support its projected operating requirements and financial commitments for at least the next 12 months from the date of this Quarterly Report. The operating requirements include the current development plans for Bryostatin-1, the Company’s novel drug candidate targeting the activation of Protein Kinase C Epsilon and other development projects. The financial commitments include the potential redemption of the Series C Convertible Preferred Stock for cash.

The Company expects to need additional capital in order to initiate and pursue potential additional development projects, including the continuing development beyond the ongoing Phase 2 trial of Bryostatin-1. Any additional equity financing, if available, may not be on favorable terms and would likely be significantly dilutive to the Company’s current stockholders, and debt financing, if available, may involve restrictive covenants. If the Company is able to access funds through collaborative or licensing arrangements, it may be required to relinquish rights to some of its technologies or product candidates that the Company would otherwise seek to develop or commercialize on its own, on terms that are not favorable to the Company. The Company’s ability to access capital when needed is not assured and, if not achieved on a timely basis, will likely have a materially adverse effect on its business, financial condition and results of operations.

Other Risks and Uncertainties

The Company operates in an industry that is subject to rapid technological change, intense competition, and significant government regulation. The Company’s operations are subject to significant risk and uncertainties including financial, operational, technological and regulatory. Such factors include, but are not necessarily limited to, the results of clinical testing and trial activities, the ability to obtain regulatory approval, the limited supply of raw materials, the ability to obtain favorable licensing, manufacturing or

other agreements, including risk associated with the Company’s Cognitive Research Enterprises, Inc. (formerly known as the Blanchette Rockefeller Neurosciences Institute, or BRNI) (“CRE”) licensing agreement, and the ability to raise capital to achieve strategic objectives.

CRE has entered into a material transfer agreement with the National Cancer Institute of the National Institutes of Health (“NCI”), pursuant to which the NCI has agreed to supply bryostatin required for the Company’s pre-clinical research and clinical trials. This agreement does not provide for a sufficient amount of bryostatin to support the completion of all of the clinical trials that the Company is required to conduct in order to seek U.S. Food and Drug Administration (“FDA”) approval. Therefore, CRE or the Company would have to enter into one or more subsequent agreements with the NCI for the supply of additional amounts of bryostatin. If CRE or the Company were unable to secure such additional agreements, or if the NCI otherwise discontinues the supply, the Company would have to either secure another source of bryostatin or discontinue its efforts to develop and commercialize Bryostatin-1 for the treatment of AD. In June 2020, the Company entered into a supply agreement (the “Supply Agreement”) with BryoLogyx Inc. (“BryoLogyx”), pursuant to which BryoLogyx agreed to be the Company’s exclusive supplier of synthetic bryostatin. Pursuant to the terms of the Supply Agreement, the Company received its initial order of one gram of synthetic bryostatin. See Note 3.

Note 2 – Summary of Significant Accounting Policies:

Basis of Presentation:

The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, the unaudited condensed financial statements included herein contain all adjustments necessary to present fairly the Company’s financial position and the results of its operations and cash flows for the interim periods presented. Such adjustments are of a normal recurring nature. The results of operations for the three months ended March 31, 2025 may not be indicative of results for the full year. These unaudited condensed financial statements should be read in conjunction with the audited financial statements and the notes to those statements for the year ended December 31, 2024 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 27, 2025.

The Company is an emerging growth company as the term is used in The Jumpstart Our Business Startups Act, enacted on April 5, 2012, and has elected to comply with certain reduced public company reporting requirements, however, the Company may adopt accounting standards based on the effective dates for public entities.

Use of Estimates:

The preparation of financial statements in conformity with GAAP requires management to make significant estimates that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting period. Management evaluates its estimates on an ongoing basis using historical experience and other factors, including the general economic environment and actions it may take in the future. The Company adjusts such estimates when facts and circumstances dictate. However, these estimates may involve significant uncertainties and judgments and cannot be determined with precision. In addition, these estimates are based on management’s best judgment at a point in time and as such these estimates may ultimately differ from actual results.

Comprehensive Income (Loss)

The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 220 in reporting comprehensive income (loss). Comprehensive income (loss) is a more inclusive financial reporting methodology that includes disclosure of certain financial information that historically has not been recognized in the calculation of net income (loss). Since the Company has items of other comprehensive income (loss), comprehensive income (loss) has been reflected in the Company’s financial statements.

Net Earnings or Loss per Share:

The Company computes earnings per share using the two-class method. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings per share for common stock and any participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. The Series C Preferred Shares are considered participating securities as preferred shareholders are entitled to participate with common stockholders on an as-converted basis in any distributions of assets by the Company under the terms of the Certificate of Designations. During the three months ended March 31, 2024, the Company incurred losses attributable to common shareholders. Accordingly, the effects of any common stock equivalent would be anti-dilutive during the period and thus are not included in the calculation of diluted weighted average number of shares outstanding. The following table illustrates the computation of basic and diluted earnings per share for the three months ended March 31, 2025:

Because the Company reported a net loss for the three months ended March 31, 2024, common stock equivalents, including stock options and warrants were anti-dilutive; therefore, the amounts reported for basic and diluted loss per share were the same.

The following potentially weighted average dilutive securities have been excluded from the calculation of diluted weighted average shares outstanding as they would be anti-dilutive as determined using the treasury stock method (for the Common Stock Options and Common Stock Warrants) or the if-converted method) for the Convertible Preferred Stock, are as follows:

Cash and Cash Equivalents and Concentration of Credit Risk:

The Company considers all highly liquid cash investments with an original maturity of three months or less when purchased to be cash equivalents. At March 31, 2025, the Company’s cash balances that exceed the current insured amounts under the Federal Deposit Insurance Corporation (“FDIC”) were approximately $0.4 million. In addition, approximately $14.4 million included in cash and cash equivalents were invested in a money market fund and in U.S. treasury bills, which is not insured under the FDIC.

Fair Value of Financial Instruments:

The carrying amounts reflected in the balance sheets for prepaid expenses and payables approximate fair value due to the short maturities of these instruments. The carrying amounts for available for sale debt security, warrant liability and derivative liability approximate fair value based on level 3 of the fair value hierarchy.

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable markets.

Level 3 — Unobservable inputs which are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

Fixed Assets and Leases:

The Company has one lease which has a remaining term ofone year during the reporting period. The Company has deemed the lease immaterial and has not recorded it as an obligation on the balance sheet nor a right-of-use asset. The total future expense relating to this lease is approximately $65,000 per year.

Fixed assets are stated at cost less accumulated depreciation. Depreciation is computed on a straight line basis over the estimated useful life of the asset, which is deemed to be between three andten years.

Research and Development Costs:

All research and development costs, including costs to maintain or expand the Company’s patent portfolio licensed from CRE are expensed when incurred. Non-refundable advance payments for research and development are capitalized because the right to receive those services represents an economic benefit. Such capitalized advances will be expensed when the services occur and the economic benefit is realized. There wereno capitalized research and development services at March 31, 2025 and December 31, 2024.

Income Taxes:

The Company accounts for income taxes using the asset and liability approach which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and amounts reportable for income tax purposes under the “Separate return method.” Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The Company applies the provisions for accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company has determined that there are no significant uncertain tax positions requiring recognition in the accompanying financial statements. The tax period that is subject to examination by major tax jurisdictions is generally three years from the date of filing.

The Company had federal and state operating loss carryforwards for income tax purposes of approximately $101.7 million and approximately $103.0 million, respectively, for the period from October 31, 2012 (inception) through March 31, 2025. The net operating loss carryforwards and other deferred tax assets resulted in federal and state deferred tax assets of approximately $33.3 million at

March 31, 2025. Income tax effects of share-based payments are recognized in the financial statements for those awards that will normally result in tax deductions under existing tax law. However, the deferred tax asset is offset by a full valuation allowance.

The Company may be subject to significant U.S. federal income tax-related liabilities with respect to the Spin-Off if there is a determination that the Spin-Off is taxable for U.S. federal income tax purposes. In connection with the Spin-Off, the Company believes that, among other things, the Spin-Off should qualify as a tax-free transaction for U.S. federal income tax purposes under Section 355 and Section 368(a)(1)(D) of the Internal Revenue Code of 1986 (the “Code”). If the conclusions of the tax opinions are not correct, or if the Spin-Off is otherwise ultimately determined to be a taxable transaction, the Company would be liable for U.S. federal income tax related liabilities. Pursuant to the Separation and Distribution Agreement and the Tax Matters Agreement, Neurotrope agreed to indemnify Synaptogenix for certain liabilities, and Synaptogenix agreed to indemnify Neurotrope for certain liabilities, in each case for uncapped amounts. Indemnities that Synaptogenix may be required to provide Neurotrope are not subject to any cap, may be significant and could negatively impact Synaptogenix’s business, particularly with respect to indemnities provided in the Tax Matters Agreement. Third parties could also seek to hold Synaptogenix responsible for any of the liabilities that Neurotrope has agreed to retain. Further, the indemnity from Neurotrope may not be sufficient to protect Synaptogenix against the full amount of such liabilities, and Neurotrope may not be able to fully satisfy its indemnification obligations. Moreover, even if Synaptogenix ultimately succeeds in recovering from Neurotrope any amounts for which Synaptogenix is held liable, Synaptogenix may be temporarily required to bear these losses. At March 31, 2025 and as of the financial statement issuance date, the Company does not have any indemnification liabilities.

Under Section 382 of the Code, as amended, changes in the Company’s ownership may limit the amount of its net operating loss carryforwards that could be utilized annually to offset future taxable income, if any. This limitation would generally apply in the event of a cumulative change in ownership of the Company of more than 50% within a three-year period. In addition, the significant historical operating losses incurred by the Company may limit the amount of its net operating loss carryforwards that could be utilized annually to offset future taxable income, if any. The Company believes that operating loss carryforwards may be limited under Section 382 limitations although Section 382 studies have not been conducted to determine the actual limitations.

The Company has concluded that there are no significant uncertain tax positions requiring recognition in the accompanying financial statements. The tax period that is subject to examination by major tax jurisdictions is generally three years from the date of filing.

Recently Adopted Accounting Pronouncements:

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities to disclose significant segment expenses and other segment items on an interim and annual basis, and provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative threshold to determine its reportable segments. The new disclosure requirements are also applicable to entities that account and report as a single operating segment entity. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. The Company adopted the guidance for the annual reporting period ended December 31, 2024. There was no impact on the Company’s reportable segments identified and additional required disclosures have been included in Note 10, Segment Reporting in the Notes to Financial Statements.

Recently Issued Accounting Pronouncements:

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures which requires public entities to disclose specific categories in the effective tax rate reconciliation, as well as expanded disclosures on income taxes paid by jurisdictions. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact related to the adoption of ASU 2023-09 on its financial statement disclosures.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (Topic 220), which requires disclosure in the notes to financial statements about specific types of expenses included in the expense captions presented on the face of the statement of operations. The requirements of the ASU are effective for annual periods beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The requirements will be applied prospectively with the option for retrospective application. The Company is currently evaluating the impact related to the adoption of ASU 2024-03 on its financial statement disclosures.

Note 3 – Collaborative Agreements and Commitments:

Stanford License Agreements

On May 12, 2014, the Company entered into a license agreement (the “Stanford Agreement”) with The Board of Trustees of The Leland Stanford Junior University (“Stanford”), pursuant to which Stanford has granted to the Company a revenue-bearing, world-wide right and exclusive license, with the right to grant sublicenses (on certain conditions), under certain patent rights and related technology for the use of bryostatin structural derivatives, known as “bryologs,” for use in the treatment of central nervous system disorders, lysosomal storage diseases, stroke, cardio protection and traumatic brain injury, for the life of the licensed patents. The Company is required to use commercially reasonable efforts to develop, manufacture and sell products (“Licensed Products”) in the Licensed Field of Use (as defined in the Stanford Agreement) during the term of the licensing agreement which expires upon the termination of the last valid claim of any licensed patent under this agreement. In addition, the Company must meet specific product development milestones, and upon meeting such milestones, make specific milestone payments to Stanford. The Company must also pay Stanford royalties of 3% of net sales, if any, of Licensed Products (as defined in the Stanford Agreement) and milestone payments of up to $3.7 million dependent upon stage of product development. As of March 31, 2025, no royaltiesnor milestone payments have been earned or made.

The Company paid Stanford $70,000 upon executing the license and is obligated to pay an additional $10,000 annually as a license maintenance fee. In addition, based upon certain milestones that include product development and commercialization, the Company will be obligated to pay up to an additional $2.1 million and between 1.5% and 4.5% royalty payments on certain revenues generated by the Company relating to the licensed technology. On November 9, 2021, the Company revised the existing licensing agreement with Stanford. The revisions extended all the required future product development and commercialization milestones. The Company is currently in full compliance with the revised agreement and is moving forward on its commitments. As of March 31, 2025, no royaltiesnor milestone payments have been earned or made.

The Company has advanced the development of synthetic bryostatin by demonstrating the equivalence of the synthetic to the natural bryostatin product. The estimated cost to initiate and produce sufficient quantities of the synthetic bryostatin drug product is approximately $1.5 million. The Company is evaluating production alternatives at this time.

Mt. Sinai License Agreement

On July 14, 2014, the Company entered into an Exclusive License Agreement (the “Mount Sinai Agreement”) with the Icahn School of Medicine at Mount Sinai (“Mount Sinai”). Pursuant to the Mount Sinai Agreement, Mount Sinai granted the Company (a) a revenue-bearing, world-wide right and exclusive license, with the right to grant sublicenses (on certain conditions), under Mount Sinai’s interest in certain joint patents held by the Company and Mount Sinai (the “Joint Patents”) as well as in certain results and data (the “Data Package”) and (b) a non-exclusive license, with the right to grant sublicenses on certain conditions, to certain technical information, both relating to the diagnostic, prophylactic or therapeutic use for treating diseases or disorders in humans relying on activation of Protein Kinase C Epsilon (“PKC ε”), which includes Niemann-Pick Disease (the “Mount Sinai Field of Use”). The Mount Sinai Agreement allows the Company to research, discover, develop, make, have made, use, have used, import, lease, sell, have sold and offer certain products, processes or methods that are covered by valid claims of Mount Sinai’s interest in the Joint Patents or an Orphan Drug Designation Application covering the Data Package (“Mount Sinai Licensed Products”) in the Mount Sinai Field of Use (as such terms are defined in the Mount Sinai Agreement).

The Company is required to pay Mt. Sinai milestone payments of $2.0 million upon approval of a new drug application (“NDA”) in the United States and an additional $1.5 million for an NDA approval in the European Union or Japan. In addition, the Company is required to pay Mt. Sinai royalties on net sales of licensed product of 2.0% for up to $250 million of net sales and 3.0% of net sales over $250 million. Since inception, the Company has paid Mt. Sinai approximately $210,000 consisting of licensing fees of $135,000 plus development costs and patent fees of approximately $75,000. As of March 31, 2025, no royaltiesnor milestone payments have been earned or made.

Agreements with BryoLogyx

On June 9, 2020, the Company entered into a supply agreement (the “Supply Agreement”) with BryoLogyx Inc. (“BryoLogyx”), pursuant to which BryoLogyx agreed to serve as the Company’s exclusive supplier of synthetic bryostatin. Pursuant to the terms of the Supply Agreement, the Company placed an initial order and subsequently received one gram of current good manufacturing practice (“cGMP”) synthetic bryostatin as an active pharmaceutical ingredient to be used in a drug product (“API”). The Company may place additional orders for API beyond the initial order by making a written request to BryoLogyx no later than six months prior to the requested delivery date. The Company is not currently using synthetic bryostatin for its current Phase 2 clinical trial and will determine when to incorporate the synthetic into the clinical trial process.

In connection with the Supply Agreement, on June 9, 2020, the Company entered into a transfer agreement (the “Transfer Agreement”) with BryoLogyx. Pursuant to the terms of the Transfer Agreement, the Company agreed to assign and transfer to BryoLogyx all of the Company’s right, title and interest in and to that certain Cooperative Research and Development Agreement, dated as of January 29, 2019 (the “CRADA”), by and between the Company and the U.S. Department of Health and Human Services, as represented by the NCI, under which Bryostatin-1’s ability to modulate CD22 in patients with relapsed/refractory CD22+ disease has been evaluated to date. Pursuant to guidance provided by NCI, the Company CRADA has been cancelled and BryoLogyx has initiated a request for a new CRADA in its name. BryoLogyx will be filing its own investigational new drug application (“IND”) for CD22 with the FDA. As consideration for the transfer of rights to the CRADA, BryoLogyx has agreed to pay to the Company 2% of the gross revenue received in connection with the sale of bryostatin products, up to an aggregate payment amount of $1 million. No such revenues have been earned as of March 31, 2025.

Contingencies

Pursuant to the Separation Agreement and Tax Matters Agreement with Neurotrope, Neurotrope agreed to indemnify Synaptogenix for certain liabilities, and Synaptogenix agreed to indemnify Neurotrope for certain liabilities, in each case for uncapped amounts. Indemnities that Synaptogenix may be required to provide Neurotrope are not subject to any cap, may be significant and could negatively impact Synaptogenix’s business, particularly with respect to indemnities provided in the Tax Matters Agreement. Third parties could also seek to hold Synaptogenix responsible for any of the liabilities that Neurotrope has agreed to retain. Further, the indemnity from Neurotrope may not be sufficient to protect Synaptogenix against the full amount of such liabilities, and Neurotrope

may not be able to fully satisfy its indemnification obligations. Moreover, even if Synaptogenix ultimately succeeds in recovering from Neurotrope any amounts for which Synaptogenix is held liable, Synaptogenix may be temporarily required to bear these losses. As of the reporting date, there are no claims relating to the indemnification agreement.

Note 6 – Stockholders’ Equity:

The Company’s amended and restated certificate of incorporation authorizes it to issue 150,000,000 shares of Common Stock and 1,000,000 shares of preferred stock, par value $0.0001 per share.

September 2024 Private Placement

On September 10, 2024, the Company entered into a Securities Purchase Agreement (the “Series C Purchase Agreement”) with certain accredited investors (the “Series C Investors”), pursuant to which it agreed to sell to the Series C Investors (i) in a registered direct offering, an aggregate of 1,793 shares of the Company’s newly-designated Series C convertible preferred stock, par value $0.0001, with a stated value of $1,000 per share (the “Series C Preferred Stock”), initially convertible into up to 448,250 shares of Common Stock (the “Registered Conversion Shares”) and (ii) in a concurrent private placement, an aggregate of 3,207 shares of the Series C Preferred Stock, initially convertible into up to 801,750 shares of Common Stock (the “Unregistered Conversion Shares” and, together with the Registered Conversion Shares, the “Series C Conversion Shares”) as well as warrants (the “Series C Warrants”) to acquire up to an aggregate of 1,250,000 shares of Common Stock (the “Series B Warrant Shares”) (the registered direct offering and the concurrent private placement collectively, the “Series C Offering”).

GP Nurmenkari Inc. acted as the Series C Placement Agent. In connection with the Series C Offering, pursuant to an Engagement Letter between the Company and the Series C Placement Agent, we agreed to pay the Series C Placement Agent (i) a cash fee equal to 7.0% of the gross proceeds from any sale of securities in the Series C Offering and (ii) warrants to purchase shares of Common Stock equal to 3.0% of the number of shares of Common Stock that the Series C Preferred Stock are initially convertible into, with an exercise price of $4.00 per share and afive-year term.

The terms of the Series C Preferred Stock are as set forth in the Series C Certificate of Designations, which was filed with the Secretary of State for the State of Delaware on September 12, 2024. The Series C Preferred Stock is convertible into Series C Conversion Shares at the election of the holder at any time at the Series C Conversion Price. The Series C Conversion Price is subject to customary adjustments for stock dividends, stock splits, reclassifications and the like, and subject to price-based adjustment in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for Common Stock, at a price below the then-applicable Series C Conversion Price (subject to certain exceptions). We are required to redeem the Series C Preferred Shares in equal quarterly installments, commencing on October 31, 2024. The amortization payments due upon such redemption are payable in cash at 107% of the applicable Installment Amount (as defined in the Series C Certificate of Designations).

The holders of the Series C Preferred Shares are entitled to dividends of 5% per annum, compounded quarterly, which will be payable in cash. Upon the occurrence and during the continuance of a Triggering Event (as defined in the Series C Certificate of Designations), the Series C Preferred Shares will accrue dividends at the rate of 15% per annum. The holders of Series C Preferred Shares are entitled to vote with holders of the Common Stock as a single class on all matters that holders of Common Stock are entitled to vote upon, with the number of votes per Series C Preferred Share equal to the stated value of such Series C Preferred Share divided by the “Minimum Price” (as defined in Rule 5635 of the Listing Rules of the Nasdaq Stock Market) immediately prior to the date of the Series C Purchase Agreement.

Following the first anniversary of the initial issuance of the Series C Preferred Shares through the date that is ten calendar days thereafter, holders of Series C Preferred Shares may require the Company to redeem all or any portion of their Series C Preferred Shares in cash, pursuant to the terms set forth in the Series C Certificate of Designation.

Notwithstanding the foregoing, the Company’s ability to settle conversions is subject to certain limitations set forth in the Certificate of Designations, including a limit on the number of shares that may be issued until the time, if any, that the Company receives Nasdaq Stockholder Approval. The Company received Nasdaq Stockholder Approval of these matters at a meeting held on December 6, 2024. Further, the Series C Certificate of Designations contains a certain beneficial ownership limitation after giving effect to the issuance of shares of Common Stock issuable upon conversion of the Series C Certificate of Designations or Series C Warrants.

The Series C Certificate of Designations includes certain Triggering Events (as defined in the Series C Certificate of Designations), including, among other things, the failure to file and maintain an effective registration statement covering the sale of the holder’s securities registrable pursuant to the Series C Registration Rights Agreement (defined below) and the Company’s failure to pay any amounts due to the holders of the Series C Preferred Shares when due. In connection with a Triggering Event, each holder of Series C Preferred Shares will be able to require the Company to redeem in cash any or all of the holder’s Series C Preferred Shares at a premium set forth in the Series C Certificate of Designations.

The Company is subject to certain affirmative and negative covenants regarding the incurrence of indebtedness, acquisition and investment transactions, the existence of liens, the repayment of indebtedness, the payment of cash in respect of dividends (other than dividends pursuant to the Series C Certificate of Designations), distributions or redemptions, and the transfer of assets, among other matters.

The Series C Warrants are exercisable immediately at the Series C Exercise Price and expire five years from the date of issuance. The Series C Exercise Price is subject to customary adjustments for stock dividends, stock splits, reclassifications and the like, and subject to price-based adjustment, on a “full ratchet” basis, in the event of any issuances of Common Stock, or securities convertible, exercisable or exchangeable for Common Stock, at a price below the then-applicable Series C Exercise Price (subject to certain exceptions). There is no established public trading market for the Series C Warrants and the Company does not intend to list the Series C Warrants on any national securities exchange or nationally recognized trading system.

In connection with the Series C Purchase Agreement, on September 10, 2024, the Company and the Series C Investors entered into a Registration Rights Agreement, pursuant to which the Company was required to file a resale registration statement with the SEC to register for resale 200% of the Unregistered Conversion Shares and 200% of the Series C Warrant Shares. The Company filed a registration statement for the resale of such securities on October 10, 2024, which was declared effective by the SEC on October 21, 2024. The Company also agreed to other customary obligations regarding registration, including indemnification and maintenance of the effectiveness of the registration statement.

Series B Common Stock Warrants

Pursuant to a November 17, 2022 private placement, the Company issued to investors warrants and, pursuant to its advisory agreements, the Company issued to its advisor additional warrants with the same terms to purchase 2,323 shares of Common Stock with the same terms (the “Series B Broker Warrants”). The Series B Broker Warrants are within the scope of ASC 718 pursuant to ASC 718-10-20 but are subject to liability classification as they would be required to be classified as liabilities in accordance with ASC 480.

The warrants were determined to be within the scope of ASC 480-10 as they are puttable to the Company at the Holders’ election upon the occurrence of a Fundamental Transaction (as defined in the agreements). As such, the Company recorded the warrants as a liability at fair value with subsequent changes in fair value recognized in earnings.

During the three months ended March 31, 2025 and 2024, the Company recorded a gain of $112,000 and $58,000, respectively related to the change in fair value of the Series B warrant liability, which is recorded in other income (expense) on the Statements of Comprehensive (Income) Loss. The fair value of the warrants of approximately $198,000 was estimated at March 31, 2025 utilizing the

Black Scholes Model using the following weighted average assumptions: dividend yield 0%; remaining term of 2.64 years; equity volatility of 120%; and a risk-free interest rate of 3.82%.

Accounting Treatment of September 2024 Private Placement

Series C Preferred Shares

The Series C Preferred Shares were determined to be more akin to a debt-like host than an equity-like host. The Company identified the following embedded features that are not clearly and closely related to the debt host instrument: 1) certain contingent redemption options and 2) variable share-settled installment conversions. These features were bundled together, assigned probabilities of being affected and measured at fair value. Subsequent changes in fair value of these features are recognized in the Consolidated Statement of Operations. The Company estimated the approximately $6.1 million fair value of the bifurcated embedded derivative at issuance using a discounted cash flow scenario model, with the following inputs: the fair value of our common stock of $2.85 on the issuance date, estimated equity volatility of 90.0%, the time to maturity of 1.57 years, the installment redemption premium of 107%, a market interest rate of 5.53%, a risk-free rate of 3.76%, and dividend rate of 5%. The fair value of the bifurcated derivative liability was estimated utilizing the with and without method which uses the probability weighted difference between the scenarios with the derivative and the plain vanilla maturity scenario without a derivative.

The discount to the fair value is included as a reduction to the carrying value of the Series C Preferred Shares. During 2024, the Company recorded a total discount of approximately $5 million upon issuance of the Series C Preferred Shares as the fair value of the liabilities required to be remeasured at fair value exceeded the gross proceeds. Upon issuance it was deemed probable that the Series C Preferred Shares will be redeemed; therefore, for the three months ended March 31, 2025, the Company recorded accretion expense of approximately $1.1 million to adjust the Series C Preferred Shares up to their redemption amount pursuant to ASC 480-10-S99-3A.

During the quarter ended March 31, 2025, the Company recorded a loss of $79,000 related to the change in fair value of the derivative liability corresponding to the Series C Preferred Shares which is recorded in other income (expense) on the Statements of Comprehensive (Income) Loss. The Company estimated the approximately $6.2 million fair value of the bifurcated embedded derivative as of March 31, 2025 using a discounted cash flow scenario model, with the following inputs: the fair value of its common stock of $2.42 on the valuation date, estimated equity volatility of 110.0%, the time to maturity of 1.02 years, the installment redemption premium of 107%, a market interest rate of 6.14%, a risk-free rate of 3.87% and dividend rate of 5%.

Series C Common Stock Warrants

Pursuant to the Series C Offering, the Company issued to investors Series C Warrants to purchase 1,250,000 shares of Common Stock, with an exercise price of $4.00 per share (subject to adjustment), for a period offive years from the date of issuance. Pursuant to its advisory agreements, the Company issued to its advisor additional Series C Warrants to purchase 37,500 shares of Common Stock with the same terms (the “Series C Broker Warrants”). The Series C Broker Warrants are within the scope of ASC 718 pursuant to ASC 718-10-20 but are subject to liability classification as they would be required to be classified as liabilities in accordance with ASC 480.

The Series C Warrants were determined to be within the scope of ASC 480-10 as they are puttable to the Company at Holders’ election upon the occurrence of a Fundamental Transaction (as defined in the agreements). As such, the Company recorded the Series C Warrants as a liability at fair value with subsequent changes in fair value recognized in earnings.

During the three months ended March 31, 2025, the Company recorded a gain of approximately $1.2 million related to the change in fair value of the Series C warrant liability which is recorded in other income (expense) on the Condensed Statements of Comprehensive (Income) Loss. The fair value of the Series C Warrants of approximately $2.2 million was estimated at March 31, 2025 utilizing the Black Scholes Model using the following weighted average assumptions: dividend yield 0%; remaining term of 4.45 years; equity volatility of 110% and a risk-free interest rate of 3.87%.

Reverse Stock Split

At the Company’s annual meeting of stockholders held on December 20, 2023, the stockholders approved an amendment to the Company’s amended and restated certificate of incorporation to effect a reverse stock split of the Company’s outstanding shares of Common Stock, at any ratio between 1-for-8 and 1-for-25. On April 4, 2024, the Company effected the Reverse Stock Split. As a result of the Reverse Stock Split, every 25 shares of the Common Stock outstanding before the Reverse Stock Split was combined and

reclassified into one share of Common Stock. These financial statements have been adjusted to retrospectively reflect the Reverse Stock Split.

Based upon the Reverse Stock Split and Series C Offering, the total number of Series B Warrants held by the Series B investors has been adjusted to 123,976 with an exercise price of $2.8586 per share. In addition, the Series B Conversion Price was adjusted to $2.8656 per Series B Preferred Share.

The Company currently estimates, beginning at the closing date of the Series B offering, implied volatility factor for all options and warrants based upon a blend of the Parent Company’s and Company’s historical volatility. Up until November 21, 2022, the Company computed implied volatility based upon a blend of the Parent Company’s and Company’s historical volatility along with the volatility of selected comparable publicly traded companies as, at that time, the Company lacked sufficient historical stock trading activity. It incorporated the historical volatility of the Parent Company as the Parent Company’s historical volatility provides a good estimation of the Company’s volatility since its operations were identical to the Company’s prior to the Spin-Off.
