NOTE 1. ORGANIZATION

NovaBay Pharmaceuticals, Inc. (the “Company” or “our,” “we,” or “us”) was previously focused on the development and sale of eyecare, wound care, and skin care products. The Company may continue to manufacture wound care products domestically in the United States and export finished goods to China.

| ● | The Avenova Asset Divestiture closed on January 17, 2025 in which we sold our primary eyecare business (see Note 14, “Avenova Asset Divestiture and Bridge Loan”);
| ● | The PhaseOne Divestiture closed on January 8, 2025 in which we sold our PhaseOne trademark (see Note 15, “PhaseOne Divestiture”); and
| ● | The DERMAdoctor Divestiture closed on March 12, 2024 in which we sold our primary skin care business (see Note 16, “DERMAdoctor Divestiture”).

The Company was incorporated under the laws of the State of California on January 19, 2000, as NovaCal Pharmaceuticals, Inc. It had no operations until July 1, 2002, on which date it acquired all of the operating assets of NovaCal Pharmaceuticals, LLC, a California limited liability company. In February 2007, the Company changed its name from NovaCal Pharmaceuticals, Inc. to NovaBay Pharmaceuticals, Inc. In June 2010, the Company changed the state in which it was incorporated pursuant to the Reincorporation and is now incorporated under the laws of the State of Delaware. All references to “the Company” herein refer to the California corporation prior to the date of the Reincorporation and to the Delaware corporation on and after the date of the Reincorporation. The Company is managed as one reportable segment consisting of its ongoing wound care business.

On May 30, 2024, the Company effected the Reverse Stock Split. Except as otherwise specifically noted, all share numbers, share prices, exercise/conversion prices and per share amounts have been adjusted, on a retroactive basis, to reflect the Reverse Stock Split.

Discontinued Operations

Historical financial results related to each of the businesses and assets divested above are now presented as discontinued operations in our unaudited condensed consolidated financial statements (see Note 14, “Avenova Asset Divestiture and Bridge Loan”; Note 15, “PhaseOne Divestiture”; and Note 16, “DERMAdoctor Divestiture”).

Previous Plan of Dissolution and Strategic Direction of the Company

The Company’s board of directors (the “Board”) unanimously approved each of the divestitures above and subsequently evaluated additional strategic options available to the Company. During this time, the Board pursued a voluntary liquidation and dissolution under Delaware law (the “Dissolution”) pursuant to a Plan of Complete Liquidation and Dissolution (the “Plan of Dissolution”) which was approved at a special meeting of stockholders that was held on April 16, 2025 (the “2025 Special Meeting”). Although stockholder approval of the Dissolution was received, the Board was authorized to subsequently determine, in its discretion, whether or not to proceed with the Dissolution. The Board ultimately determined not to pursue the Dissolution and simultaneously entered into the 2025 Preferred Stock Purchase Agreement (see Note 8, “Financing Activities”), Series E Preferred Stock Closing (see Note 19, “Subsequent Events”) and October 2025 Pre-Funded Warrants (see Note 19, “Subsequent Events”). As part of its broader capital allocation review, the Company has begun evaluating opportunities within emerging financial infrastructure and network-based markets. These opportunities may include select blockchain-based assets that the Company believes could enhance capital efficiency and long-term stockholder value.

Liquidity

Based on our funds available on September 30, 2025, together with net proceeds from the issuance of the Series E Preferred Stock and October 2025 Pre-Funded Warrants (see Note 19, “Subsequent Events”), management believes that the Company’s existing cash and cash equivalents will be sufficient to enable the Company to meet its planned operating expenses at least through November 7, 2026; however, as referenced above, the Company is considering adjustments to its strategic direction. As a result of any change in the Company’s strategic direction, there may be circumstances that cause the Company to adjust its anticipated spending in the near term.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and are expressed in U.S. dollars. In management’s opinion, the unaudited condensed consolidated financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of the Company’s financial position and operating results.

Table of Contents

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its former wholly owned subsidiary, DERMAdoctor, which was fully divested on March 12, 2024, as of and for the nine months ended September 30, 2024. All significant intercompany balances and transactions have been eliminated in consolidation. See also Note 16, “DERMAdoctor Divestiture.” The accompanying unaudited condensed consolidated financial statements include only the accounts of the Company for the three and nine months ended September 30, 2025.

Financial Statement Reclassification

Certain account balances from prior periods have been reclassified in these unaudited condensed consolidated financial statements to conform to current period classifications. Prior year amounts have been modified in these unaudited condensed consolidated financial statements to properly report amounts under current operations and discontinued operations (see Note 14, “Avenova Asset Divestiture and Bridge Loan”; Note 15, “PhaseOne Divestiture”; and Note 16, “DERMAdoctor Divestiture”).

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Actual results may differ significantly from those estimates. Significant estimates made by management include, but are not limited to, contract liabilities related to product sales such as product returns, assumptions for valuing warrants, assumptions for valuing derivative liabilities, long-lived asset impairments, stock-based compensation, income taxes and other contingencies.

These estimates are based on management’s best estimates and judgment. Actual results may differ from these estimates. Estimates, judgments, and assumptions are continuously evaluated and are based on management’s experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Uncertainty about these assumptions, judgments and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods.

Segment Information

The Company has one operating and reportable segment that encompasses the Company’s consolidated ongoing operations, reflecting the integrated nature of its currently limited business. The Company’s chief operating decision maker (“CODM”) is its chief executive officer. The measurement of profit and loss is the segment loss, which is equivalent to the “net loss from continuing operations” as reported on the Company's condensed consolidated statements of operations. The measurement of segment assets is reported on the Company’s condensed consolidated balance sheet as “total assets.” The CODM allocates resources to the Company’s initiatives and assesses performance on a consolidated basis, focused on the maintenance of the Company’s cash resources while assessing strategic alternatives on an ongoing basis and maintaining its public company status. The CODM is not regularly provided with disaggregated actual expense information, other than the actual expense information included in the condensed consolidated statements of operations, as the Company’s integrated operating model emphasizes shared resources and centralized decision-making.

Unaudited Condensed Consolidated Interim Financial Information

The accompanying unaudited condensed consolidated financial statements and related disclosures have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only recurring adjustments, necessary for a fair presentation.

The year-end condensed consolidated balance sheet data was derived from the audited consolidated financial statements but does not include all disclosures required by U.S. GAAP. The unaudited condensed consolidated results of operations for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future year or interim period.

The unaudited condensed consolidated financial statements and notes included herein should be read in conjunction with the annual consolidated financial statements and notes for the year ended December 31, 2024, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the SEC on April 2, 2025 (collectively, the “2024 Annual Report”).

Cash, Cash Equivalents, and Highly Liquid Restricted Cash

The Company considers all highly-liquid instruments with a stated maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents are stated at cost, which approximates fair value. As of September 30, 2025 and December 31, 2024, the Company’s cash and cash equivalents were held in a major financial institution in the United States.

The following table provides a reconciliation of the cash, cash equivalents, and restricted cash reported in the condensed consolidated balance sheets (in thousands):

|  | September 30, |  |  | December 31, |
|  | 2025 |  |  | 2024 |
Cash and cash equivalents |  | $ | 2,309 |  |  | $ | 430 |
Restricted cash included in other assets |  |  | 393 |  |  |  | 477 |
Total cash, cash equivalents, and restricted cash in the condensed consolidated statements of cash flows |  | $ | 2,702 |  |  | $ | 907 |

The restricted cash amount included in other assets on the condensed consolidated balance sheets represents amounts held as certificates of deposit for long-term financing and lease arrangements as contractually required by our financial institution and landlord.

Concentrations of Credit Risk and Major Partners

Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash, cash equivalents and restricted cash. The Company maintains deposits of cash, cash equivalents and restricted cash with a major financial institution in the United States.

The Company has a significant amount of its cash balances at financial institutions which throughout the year regularly exceed the federally insured limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows.

Fair Value of Financial Assets and Liabilities

The Company’s financial instruments include cash and cash equivalents, restricted cash, accounts payable, accrued liabilities and warrant liabilities. The Company’s cash and cash equivalents, restricted cash, accounts payable, and accrued liabilities are carried at cost, which management believes approximates fair value due to the short-term nature of these instruments.

The Company follows Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures, with respect to assets and liabilities that are measured at fair value on a recurring basis and nonrecurring basis. Under this standard, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The standard also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. There are three levels of inputs that may be used to measure fair value:

Level 1 – quoted prices in active markets for identical assets or liabilities;

Level 2 – quoted prices for similar assets and liabilities in active markets or inputs that are observable; and

Level 3 – inputs that are unobservable (for example, cash flow modeling inputs based on assumptions).

Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

See additional information in Note 3, “Fair Value Measurements.”

Property and Equipment, Net

Property and equipment are stated at cost, less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the related assets of five to seven years for office and laboratory equipment, three to five years for computer equipment and software, and five to seven years for furniture and fixtures. Leasehold improvements are amortized over the shorter of the estimated useful life of the asset or the lease term.

The costs of normal maintenance, repairs, and minor replacements are expensed as incurred.

Table of Contents

Impairment of Long-Lived Assets

The Company’s long-lived assets are reviewed for impairment in accordance with ASC 360, Property, Plant and Equipment, which requires that companies consider whether events or changes in facts and circumstances, both internally and externally, may indicate that an impairment of long-lived assets held for use are present. The Company reviews long-lived assets for impairment at least annually or whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the asset, the assets are written down to their estimated fair values and the loss is recognized in the condensed consolidated statements of operations. The Company recorded $87 thousand and $676 thousand in property and equipment impairment losses for the three and nine months ended September 30, 2025, respectively. This included $3 thousand and $33 thousand for fixed assets including leasehold improvements for the three and nine months ended September 30, 2025, respectively and $84 thousand and $643 thousand for operating lease right-of-use assets for the three and nine months ended September 30, 2025, respectively. The Company did not record any impairment losses for the three and nine months ended September 30, 2024.

Leases

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes its incremental borrowing rate, which is the rate incurred to borrow, on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. Certain adjustments to the right-of-use assets may be required for items such as initial direct costs paid or incentives received.

The Company has elected to combine lease and non-lease components as a single component. This will potentially result in the initial and subsequent measurement of the balances of the right-of-use assets and lease liability for leases being greater than if the policy election was not applied. Leases include variable components (e.g., common area maintenance) that are paid separately from the monthly base payment based on actual costs incurred and therefore were not included in the right-of-use assets and lease liability but are reflected as an expense in the period incurred.

The lease expense is recognized over the expected term on a straight-line basis. Operating leases are recognized in the condensed consolidated balance sheets as right-of-use assets, operating lease liabilities current and operating lease liabilities non-current.

The Company recorded $84 and $643 thousand in impairment losses for the three and nine months ended September 30, 2025, respectively, related to operating lease right-of-use assets.

Common Stock Warrants

The Company accounts for common stock purchase warrants issued in connection with its equity offerings in accordance with the provisions of ASC 480, Distinguishing Liabilities from Equity, and ASC 815, Derivatives and Hedging (ASC 815).

The Company classifies as equity any warrants that (i) require physical share settlement or net-share settlement or (ii) give the Company a choice of net-cash settlement (physical share settlement or net-share settlement). The Company classifies as liabilities any warrants that (i) require net-cash settlement, (ii) give the counterparty a choice of net-cash physical settlement or net-share settlement. In accordance with ASC 815, the Company also classifies as liabilities any warrants for which the shares underlying the contract are subject to stockholder approval before the warrant can be exercised.

For warrants that are classified as liabilities, the Company records the fair value of the warrants upon issuance and at each balance sheet date with changes in the estimated fair value recorded as a non-cash gain or loss in the condensed consolidated statements of operations. The fair values of these warrants are determined using the Black-Scholes option pricing model. These values are subject to a significant degree of management’s judgment. See Note 3, “Fair Value Measurements,” subheading “Black Scholes Valuation Models and Assumptions” and Note 10, “Common Stock Warrants.”

Amendments to warrant terms are recorded as a non-cash gain or loss on modification of common stock warrants. The gain or loss represents the decrease or increase in the fair value of the amended warrants when comparing the value immediately before and after amendment using the Black-Scholes option pricing model. See Note 3, “Fair Value Measurements,” subheading “Black Scholes Valuation Models and Assumptions.”

Preferred Stock

Preferred stock that is redeemable at the option of the holder or upon events not solely within the control of the Company is classified as mezzanine (temporary) equity in accordance with ASC 480-10-S99-3A. Such instruments are initially recorded at fair value, net of issuance costs, and are not accreted to redemption value unless redemption becomes probable.

Table of Contents

Terms of the Company’s Preferred Stock have historically included a Ratchet whereby the applicable conversion price could be adjusted (as defined and described in Note 11, “Stockholders’ Equity (Deficit)”). The applicable Ratchet provisions of the Company’s outstanding Preferred Stock terminated during the quarter ended March 31, 2024. Prior to a termination, when a conversion price for outstanding Preferred Stock was adjusted under the Ratchet, the Company recorded a deemed dividend as a reduction to income available to common stockholders. In accordance with ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), the deemed dividend was measured as the difference between (1) the fair value of the Preferred Stock immediately prior to the conversion price adjustment (but without the Ratchet anti-dilution protection feature) and (2) the fair value of the Preferred Stock immediately after the conversion price adjustment (but without the Ratchet anti-dilution protection feature). These fair values were determined using the Black Scholes option pricing model. These values are subject to a significant degree of management’s judgment. See also Note 3, “Fair Value Measurements,” subheading “Black Scholes Valuation Models and Assumptions.”

Stock-Based Compensation

The Company’s stock-based compensation includes grants of stock options and restricted stock units (“RSUs”) to employees, consultants and non-employee directors. The expense associated with these grants is recognized in the Company’s condensed consolidated statements of operations based on their fair values as they are earned under the applicable vesting terms. For stock options granted, the fair value of the stock options is estimated using a Black-Scholes option pricing model. The Company accounts for RSUs issued to employees and non-employees (directors, consultants and advisory board members) based on the fair market value of the Company’s common stock on the date of issuance. See Note 12, “Stock-Based Compensation” for further information regarding stock-based compensation expense and the assumptions used in estimating the expense.

Income Taxes

The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized if it is more likely than not that some portion or the entire deferred tax asset will not be recognized.

Net (Loss) Income per Share

The Company computes net (loss) income per share by presenting both basic and diluted loss per share (“EPS”) as shown in the Company’s condensed consolidated statements of operations (unaudited).

Basic EPS is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS gives effect to all dilutive potential common shares outstanding during the period, including stock options and warrants, using the treasury stock method. In computing diluted EPS, the average stock price for the period is used to determine the number of shares assumed to be purchased from the exercise of stock options or warrants. Potentially dilutive common share equivalents are excluded from the diluted EPS computation in net loss periods if their effect would be anti-dilutive.

The following table provides a reconciliation of the numerator and denominator used for basic and diluted (loss) earnings per share (in thousands):

Recent Accounting Pronouncements

In November 2024, the FASB issued Accounting Standards Update (“ASU”) No. 2024-03, Disaggregation of Income Statement Expenses (“ASU 2024-03”). ASU 2024-03 is intended to increase transparency and provide investors with more detailed information about the nature of expenses reported on the face of the statements of operations. ASU 2024-03 does not change the requirements for the presentation of expenses on the face of the statements of operations. Under ASU 2024-03, entities are required to disaggregate, in tabular format, expenses presented on the face of the statements of operations if they include any of the following expense categories: employee compensation, depreciation, intangible asset amortization, and depreciation or depletion. For any remaining items within each relevant expense caption, entities must provide a qualitative description of the nature of those expenses. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. While the adoption of ASU 2024-03 is not expected to have an effect on our consolidated financial statements, it is expected to result in incremental disclosures within the notes to our condensed consolidated financial statements. The Company is currently evaluating ASU 2024-03 and does not expect it to have a material effect on the Company’s condensed consolidated financial statements.

For information regarding additional accounting pronouncements that could affect our business, results of operations, financial condition, and liquidity, see Note 2, “Summary of Significant Accounting Policies” included in our 2024 Annual Report. The Company continues to evaluate the potential impact of adopting the new accounting guidance on its consolidated financial position, results of operations and cash flows.

Black Scholes Valuation Models and Assumptions

The Company utilizes a Black Scholes model for various valuations as outlined throughout this report. The following tables summarize the assumptions utilized for valuations impacting results for the periods reported. See also Note 12, “Stock-Based Compensation” for related Black Scholes valuation assumptions.

Warrant Liabilities

Certain of the Company’s warrants were subject to stockholder approval upon issuance or amendment and prior to exercise. Warrants requiring stockholder approval are recorded as a liability at fair value upon issuance or amendment and continue to be recorded as a liability at fair value at each reporting date until stockholder approval occurs at which time they are transferred to stockholders’ equity at their fair value on the date of approval. Fair value was determined using a Black Scholes model as outlined below. See Note 10, “Common Stock Warrants” for additional information and the definitions of the Company’s warrants.

Preferred Stock Conversion Price Adjustments

Terms of the Company’s outstanding Preferred Stock historically included a Ratchet whereby the applicable conversion price could be adjusted (see Note 11, “Stockholders’ Equity (Deficit)”). The applicable Ratchet provisions of the Company’s outstanding Preferred Stock terminated during the quarter ended March 31, 2024. Prior to its termination, when a conversion price for outstanding Preferred Stock was adjusted under the Ratchet, the Company recorded a deemed dividend as a reduction to income available to common stockholders. In accordance with ASC 820, the deemed dividend is measured as the difference between (1) the fair value of the Preferred Stock immediately prior to the conversion price adjustment (but without the Ratchet anti-dilution protection feature) and (2) the fair value of the Preferred Stock immediately after the conversion price adjustment (but without the Ratchet anti-dilution protection feature).

NOTE 7. COMMITMENTS AND CONTINGENCIES

As permitted under Delaware law and in accordance with its bylaws, the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is or was serving at the Company’s request in such capacity. The term of the indemnification period is for the officer’s or director’s lifetime. The maximum amount of potential future indemnification is unlimited; however, the Company has a director and officer insurance policy that limits its exposure and may enable it to recover a portion of any future payments. The Company believes the fair value of these indemnification agreements is minimal. Accordingly, it has not recorded any liabilities for these agreements as of September 30, 2025 or December 31, 2024.

In the normal course of business, the Company provides indemnification of varying scope under its agreements with other entities, typically its suppliers and others, including in connection with capital raises transactions. Additionally, the Company provided for certain indemnification in conjunction with the Avenova Asset Divestiture (see Note 14, “Avenova Asset Divestiture and Bridge Loan”). Pursuant to these agreements, it generally indemnifies, holds harmless, and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified parties in connection with the use or testing of its products or product candidates or with any U.S. patent or any copyright or other intellectual property infringement claims by any third party with respect to its products. The term of these indemnification agreements is generally perpetual. The potential future payments the Company could be required to make under these indemnification agreements are unlimited. Historically, costs related to these indemnification provisions have been immaterial. The Company also maintains various liability insurance policies that limit its exposure. As a result, it believes the fair value of these indemnification agreements is minimal. Accordingly, the Company has not recorded any liabilities for these agreements as of September 30, 2025 or December 31, 2024.

Legal Matters

From time to time, the Company is subject to various legal proceedings, as well as demands, claims and threatened litigation, which arise in the normal course of our business. The ultimate outcome of any litigation or other legal dispute is uncertain. When a loss related to a legal proceeding or claim is probable and reasonably estimable, the Company accrues its best estimate for the ultimate resolution of the matter. If one or more legal matters are resolved against the Company in a reporting period for an amount above expectations, the Company’s financial condition and operating results for that period may be adversely affected. As of September 30, 2025 and December 31, 2024, there were no legal matters that, in the opinion of management, would ultimately result in liability that would have a material adverse effect on the Company’s financial position, results of operations or cash flows. Any outcome, whether favorable or unfavorable, may materially and adversely affect the Company due to legal costs and expenses, diversion of management attention and other factors. The Company cannot provide assurance that additional contingencies of a legal nature or contingencies having legal aspects will not be asserted against it in the future, and these matters could relate to prior, current, or future transactions or events.

Leases

The Company leases office space for its corporate headquarters located in Emeryville, California. The current lease term expires on July 31, 2027. The Company recorded $84 and $643 thousand in impairment losses for the three and nine months ended September 30, 2025, respectively, related to operating lease right-of-use assets.

Lease costs for the three and nine months ended September 30, 2025 and 2024 were as follows (in thousands):

|  | For the Three Months Ended September 30, |  |  | For the Nine Months Ended September 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Operating lease – expense |  | $ | 50 |  |  | $ | 100 |  |  | $ | 173 |  |  | $ | 200 |

2025 Preferred Stock Purchase Agreement

On August 19, 2025, the Company entered into a securities purchase agreement (the “2025 Preferred Stock Purchase Agreement”) with David E. Lazar, that provides for the Company to sell in a private placement (i) an aggregate of 481,250 shares of Series D Preferred Stock convertible into an aggregate of 77.0 million shares of Common Stock for $3.85 million and (ii) an aggregate of 268,750 shares of Series E Preferred Stock convertible into an aggregate of 43.0 million shares of Common Stock for an additional $2.15 million.

Simultaneous to entering into the 2025 Preferred Stock Purchase Agreement on August 19, 2025, Mr. Lazar completed the purchase of the 481,250 shares of Series D Preferred Stock from the Company at a price of $8.00 per share for aggregate gross proceeds of $3.85 million and net proceeds to the Company of $3.79 million after deducting $64 thousand of issuance costs (the “Initial Series D Preferred Purchase”). The 2025 Preferred Stock Purchase Agreement provided for the ability of Mr. Lazar to assign, transfer and/or sell his shares of Series D Preferred Stock, Series E Preferred Stock, and/or his right acquire such securities. As further described in Note 19, “Subsequent Events”, on October 9, 2025, Mr. Lazar entered into an agreement to effect such transfer.

Since the Common Stock is currently listed on the NYSE American, LLC (“NYSE American”), and among these requirements are Section 713(a) and (b) of the NYSE American Company Guide (the “Company Guide”). Section 713(a) of the Company Guide requires stockholder approval in connection with any transaction, other than a public offering, involving the sale, issuance, or potential issuance, of common stock or securities convertible into common stock, equal to 20.0% or more of presently outstanding stock for less than the greater of book or market value. Section 713(b) of the Company Guide requires stockholder approval of a transaction, other than a public offering, involving the sale, issuance or potential issuance by an issuer of common stock (or securities convertible into, or exercisable for, common stock) when the issuance or potential issuance of additional shares may result in a change of control of the issuer. As a result of the significant number of shares of Common Stock that may be issued upon the future conversion of the Series D Preferred Stock and Series E Preferred Stock compared to the currently issued and outstanding shares of Common Stock as provided above, the Company was required to obtain stockholder approval in accordance with the Company Guide Rule 713(a) and Rule 713(b) for Mr. Lazar to be able to convert the Series D Preferred Stock and the Series E Preferred Stock (the “Conversion Approval”).

Conversion Approval was obtained subsequent to September 30, 2025, on October 16, 2025. See additional discussion in Note 19, “Subsequent Events”.

On October 16, 2025, subsequent to September 30, 2025 and the Conversion Approval, the Company completed the sale of 268,750 shares of Series E Preferred Stock at a price of $8.00 per share for aggregate gross proceeds of $2.15 million. See additional discussion in Note 19, “Subsequent Events”.

2025 Warrant Exchange and Issuance of Series F Preferred Stock

On August 19, 2025, simultaneous with the signing of the 2025 Preferred Stock Purchase Agreement, the Company entered into warrant exchange agreements (the “Series F Agreements”) with each of Anson Investments Master Fund LP, Hudson Bay Capital Management LP and Armistice Capital, LLC (collectively, the “Series F Holders”). The Series F Agreements provide for the irrevocable surrender and cancellation of all warrants beneficially owned by the Series F Holders, in exchange for the Company issuing (i) an aggregate of 1,986,565 shares of Series F Preferred Stock and (ii) an aggregate cash payment of $525,000 to the Series F Holders. Warrants exercisable for an aggregate of 1,988,283 shares of common stock were surrendered and cancelled in conjunction with the Series F Agreements. The Series F Agreements also include a “most favored nations” provision that would increase the amount paid to the Series F Holders if, after the effective date of the Series F Agreements, another holder of the Company’s Common Stock purchase warrants receives a higher amount per underlying warrant; except that this provision shall not apply to (i) settlements with retail investor warrant holders that (1) individually is less than or equal to six and thirty hundredths percent (6.30%) of a Series F Holder’s total warrants outstanding or (2) in the aggregate is less than or equal to twelve and seventy hundredths percent (12.70%) of a Series F Holder’s total warrants outstanding or (ii) prior warrant settlements by the Company.

Because the carrying value of the Common Stock Warrants cancelled in conjunction with the Series F Agreements exceeded the total cash payment made and carry value of the Series F Preferred Stock issued, the Company recorded a deemed capital contribution of $433 thousand upon entering the Series F Agreements.

2024 Public Offering

On July 26, 2024, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Ladenburg Thalmann & Co., Inc., as the sole underwriter (the “Underwriter”), relating to the issuance and sale in a public offering (the “2024 Public Offering”) of (i) 1,158,566 shares of common stock and 2,041,814 pre-funded warrants, in lieu of shares of common stock (the “July 2024 Pre-Funded Warrants”), (ii) 3,200,380 Series F-1 warrants to purchase up to 3,200,380 shares of common stock (the “Series F-1 Warrants”), (iii) 3,200,380 Series F-2 warrants to purchase up to 3,200,380 shares of common stock (the “Series F-2 Warrants”) and (iv) 3,200,380 Series F-3 warrants to purchase up to 3,200,380 shares of common stock (the “Series F-3 Warrants”, and together with the Series F-1 Warrants and Series F-2 Warrants, the “July 2024 Warrants”).

The Series F-1 Warrants had an exercise price of $1.10 per share at issuance, were exercisable immediately upon issuance, and will expire on the five-year anniversary of the date of issuance. The Series F-2 Warrants had an exercise price of $1.10 per share at issuance, were exercisable immediately upon issuance, and have since expired on the six-month anniversary of the date of issuance on January 29, 2025. The Series F-3 Warrants had an exercise price of $1.10 per share at issuance, were exercisable immediately upon issuance, and expired on the one-year anniversary of the date of issuance. The July 2024 Pre-Funded Warrants were immediately exercisable at a nominal exercise price of $0.01 per share and could be exercised at any time until the July 2024 Pre-Funded Warrants were exercised in full.

The July 2024 Warrants included a one-time down round feature adjustment where the exercise price was automatically reset to a price equal to the lesser of (i) the then exercise price and (ii) 90% of the volume weighted average prices for the five (5) trading days immediately preceding the date that is sixty calendar days after issuance of the July 2024 Warrants as applicable. Such down round feature adjustment was triggered on September 27, 2024, which resulted in a reduced exercise price of $0.66 for all of the July 2024 Warrants.

The exercise price and number of shares of common stock issuable upon exercise of the July 2024 Warrants is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting the common stock and the exercise price. Subject to limited exceptions, a holder may not exercise any portion of its July 2024 Warrants to the extent that the holder would beneficially own more than 4.99% (or, at the election of the holder prior to the date of issuance, 9.99%) of the Company’s outstanding common stock after exercise.

In addition, the Company granted the Underwriter a 45-day option to purchase up to 477,272 additional shares of common stock and/or 477,272 Series F-1 Warrants to purchase up to 477,272 shares of common stock, 477,272 Series F-2 Warrants to purchase up to 477,272 shares of common stock and 477,272 Series F-3 Warrants to purchase up to 477,272 shares of common stock, or any combination thereof, as determined by the Underwriter, at the public offering price, less underwriting discounts and commissions, in each case solely to cover over-allotments, if any.

The Underwriter partially exercised this option on July 26, 2024, for (i) 336,832 shares of common stock, (ii) 336,832 Series F-1 Warrants to purchase up to 336,832 shares of common stock, (iii) 336,832 Series F-2 Warrants to purchase up to 336,832 shares of common stock and (iv) 336,832 Series F-3 Warrants to purchase up to 336,832 shares of common stock.

The 2024 Public Offering closed on July 29, 2024, and the Company received gross proceeds of $3.9 million, without taking into account any underwriting discounts and commissions. A portion of the proceeds was used toward repaying the Secured Convertible Notes, which were repaid in full during the third quarter of 2024.

2024 Warrant Reprice Transaction

In June 2024, the Company entered into a warrant reprice transaction (the “2024 Warrant Reprice Transaction”) with certain existing holders of (i) warrants issued in September 2022 to purchase common stock, (ii) Series A-1 Warrants issued in November 2022 to purchase common stock, (iii) Series B-1 Warrants issued in May 2023 to purchase common stock, and (iv) Series B-2 Warrants issued in May 2023 to purchase common stock (collectively (i) through (iv), the “Participant Warrants”). The participants agreed to exercise a portion of their Participant Warrants at a reduced exercise price of $2.50 per share. Participant Warrants were exercised for an aggregate of 90,381 shares of common stock, resulting in gross proceeds of approximately $0.2 million.

The Company also issued participants in the 2024 Warrant Reprice Transaction a new June 2024 Warrant to purchase a number of shares of common stock equal to 100% of the shares of common stock exercised. The June 2024 Warrants are substantially similar to the Participant Warrants, except that the June 2024 Warrants will (i) be initially exercisable on the six-month anniversary of the date of issuance; (ii) have an exercise price of $2.57 per share; and (iii) have a term of five (5) years and six (6) months from the date of the closing of the 2024 Warrant Reprice Transaction.

The Company incurred total issuance costs of $96 thousand in conjunction with the 2024 Warrant Reprice Transaction. The Company incurred a $69 thousand non-cash loss on the modification of common stock warrants which was recorded in “Other expense, net” in the unaudited condensed consolidated statements of operations during the nine months ended September 30, 2024.

NOTE 9. CONVERTIBLE NOTES

Unsecured Convertible Notes

On March 24, 2024, in connection with completing certain required conditions to close the DERMAdoctor Divestiture, the Company and the holders of the Secured Convertible Notes (as defined below) entered into a First Amendment (the “First Amendment”) to the Company’s Security Agreement, dated April 27, 2023 (the “Security Agreement”), to remove all of the DERMAdoctor membership units and any assets of DERMAdoctor as collateral for the Company’s obligations pursuant to the Secured Convertible Notes and for DERMAdoctor to be removed as a party to the Security Agreement, and a Consent and Release (the “Subsidiary Guarantee Consent”), to terminate the Subsidiary Guarantee, dated April 7, 2023 (the “Subsidiary Guarantee”) (collectively, the “2024 Subsidiary Guarantee Termination”).

The Company issued $525 thousand aggregate principal amount of unsecured convertible notes (the “Unsecured Convertible Notes”) in conjunction with the 2024 Subsidiary Guarantee Termination. The 2024 Subsidiary Guarantee Termination was executed with certain holders of the Secured Convertible Notes in order to close the DERMAdoctor Divestiture (see Note 16, “DERMAdoctor Divestiture”). The Unsecured Convertible Notes are due March 25, 2026 and bear no stated interest.

The Unsecured Convertible Notes may be converted or redeemed for a conversion price equal to $4.90 per share at any time at the election of the holder up to the amount of outstanding principal at the time of conversion subject to certain limitations such as beneficial ownership limitations. As of September 30, 2025, the Unsecured Convertible Notes were convertible for up to 107,146 shares of common stock.

Upon issuance in March 2024, the lender’s conversion option under the Unsecured Convertible Notes represented an embedded call option requiring bifurcation as an embedded derivative liability because the common stock underlying the option required stockholder approval before the option could be exercised. The fair value of the embedded derivative was determined to be $159 thousand as of March 31, 2024 in accordance with a Black Scholes valuation model. See also Note 3, “Fair Value Measurements,” subheading “Black Scholes Valuation Models and Assumptions.” Upon stockholder approval on May 28, 2024, the embedded call option no longer required liability treatment and was reclassified to equity. The fair value of the embedded derivative liability was determined to be $242 thousand as of May 28, 2024. The change of $83 thousand in fair value between March 31, 2024 and May 28, 2024 was recorded as a non-cash loss on change in fair value of embedded derivative liability in the unaudited condensed consolidated statements of operations. See also Note 3, “Fair Value Measurements,” subheading “Black Scholes Valuation Models and

Assumptions.”

The discount to the note recorded for the embedded derivative liability upon issuance and debt issuance costs are being amortized to interest expense using the effective interest rate method over the term of the Unsecured Convertible Notes, assuming that the Unsecured Convertible Notes will be redeemed for cash of $525 thousand at time of maturity as of March 25, 2026. The effective interest rate on the Unsecured Convertible Notes is 144%. During the three months ended September 30, 2025 and 2024, interest expense recognized, including amortization of the issuance costs and debt discount, was $77 thousand and $20 thousand, respectively, which was included in “Other expense, net” in the unaudited condensed consolidated statements of operations. During the nine months ended September 30, 2025 and 2024, interest expense recognized, including amortization of the issuance costs and debt discount, was $170 thousand and $35 thousand, respectively, which was included in “Other expense, net” in the unaudited condensed consolidated statements of operations.

Secured Convertible Notes

In May 2023, the Company issued $3.3 million aggregate principal amount Original Issue Discount Senior Secured Convertible Debentures (the “Secured Convertible Notes”) in conjunction with a May 2023 private placement (the “2023 Private Placement”). The Secured Convertible Notes were issued with a $300 thousand original issue discount.

Beginning June 1, 2023, the Company was required to start making a monthly redemption of 1/18th of the original principal amount of the Secured Convertible Notes. Each monthly redemption reduced the outstanding principle of the Secured Convertible Note by $183 thousand.

The Secured Convertible Notes also provided for a redemption equal to up to 20% of the gross proceeds received by the Company from any financing completed while the Secured Convertible Notes were outstanding. In connection with the 2024 Warrant Reprice Transaction (see Note 11, “Stockholders’ Equity (Deficit)”), the Company made such a payment totaling $45 thousand in cash against the Secured Convertible Notes. In connection with the 2024 Public Offering (see Note 11, “Stockholders’ Equity (Deficit)”), the Company repaid the remaining balance of the Secured Convertible Notes with a payment totaling $433 thousand in cash. Upon full repayment, the Company was released from any further obligations under the Secured Convertible Notes with the lenders.

The discounts and debt issuance costs were amortized to interest expense using the effective interest rate method over the term of the Secured Convertible Notes. The effective interest rate on the Secured Convertible Notes was 173%. During the quarter ended March 31, 2024, interest expense recognized, including amortization of the issuance costs and debt discount, was $0.4 million, which was included in other expense, net in the condensed consolidated statements of operations.

Subsequent to September 30, 2025, on October 16, 2025, the Company filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware, which became effective upon filing. The amendment was approved by the Board and subsequently approved by the Company’s stockholders at the Annual Meeting of Stockholders held on October 16, 2025. The Certificate of Amendment provides that the Company is then authorized to issue an increased total of 1,500,000,000 shares of common stock. All other provisions of the Amended and Restated Certificate of Incorporation remain in full force and effect. Additional information about matters submitted to a vote of security holders and related results of the meeting can be found in the Company’s 8-K filed on October 20, 2025.

Preferred Stock

There were two series of preferred stock of the Company outstanding during the nine months ended September 30, 2025 – the Series B Non-Voting Convertible Preferred Stock (“Series B Preferred Stock”) and the Series D Non-Voting Convertible Preferred Stock (“Series D Preferred Stock”). The rights and preferences of each are described below.

Series B Preferred Stock

The Company issued 15,000 shares of Series B Preferred Stock in November 2021 in connection with a private placement transaction.

Series C Preferred Stock

The Company issued 3,250 shares of Series C Preferred Stock in November 2022 in connection with a private placement transaction. As of September 30, 2025, no shares of Series C Preferred Stock remained outstanding.

Series D Preferred Stock

The Company issued 481,250 shares of Series D Preferred Stock on August 19, 2025 in connection with the 2025 Preferred Stock Purchase Agreement (see Note 8, “Financing Activities”). As of September 30, 2025, 481,250 shares of Series D Preferred Stock were outstanding and convertible into an aggregate of 77.0 million shares of Common Stock. The Series D Preferred Stock is non‑voting, except for certain protective provisions, and is entitled to dividends and liquidation rights on an as‑converted‑to‑common basis. There are no redemption or repurchase rights that require cash settlement for the Series D Preferred Stock. The Company is not obligated to redeem or repurchase any shares of the Series D Preferred Stock.

Subsequent to September 30, 2025, on October 21, 2025, three business days after the Stockholder Approval, each share of Series D Preferred Stock automatically converted into 160 shares of Common Stock (see Note 19, “Subsequent Events”).

Series E Preferred Stock

On August 19, 2025, in connection with the 2025 Preferred Stock Purchase Agreement (see Note 8, “Financing Activities”), an investor committed to purchase shares of Series E Preferred Stock convertible into an aggregate of 43.0 million shares of Common Stock. The rights and preferences of the Series E Preferred Stock are identical to those of the Series D Preferred Stock described above except that conversion is at the option of the holder.

Subsequent to September 30, 2025, on October 16, 2025, the Company issued 268,750 shares of Series E Preferred Stock and, on October 21, 2025, each share of Series E Preferred Stock converted into 160 shares of Common Stock at the option of the holders (see Note 19, “Subsequent Events”).

Series F Preferred Stock

The Company issued 1,986,565 shares of Series F Voting Retractable Preferred Stock (the “Series F Preferred Stock”) on August 19, 2025 in connection with the Series F Agreements (see Note 8, “Financing Activities”).

The Series F Preferred Stock is not convertible into Common Stock or any other equity instrument and has no dividend rights. The Series F Preferred Stock has voting rights similar to Common Stock with each share of Series F Preferred Stock representing the voting equivalent of approximately 0.424 shares of Common Stock and a liquidation preference equivalent to common stock up to its redemption amount. The Series F Preferred Stock has a total aggregate fixed redemption value of $525,000 in cash. The redemption terms provide that, after the earlier of (i) Conversion Approval (see Note 8, “Financing Activities”) or (ii) December 31, 2025, holders may redeem the Series F Preferred Stock in exchange for $525,000 total in cash at any time. Conversion Approval was obtained by the Company subsequent to September 30, 2025 on October 16, 2025 and 639,933 shares of Series F Preferred Stock were subsequently redeemed for a $175,000 cash payment (see Note 19, “Subsequent Events”). The Company may also force redemption of outstanding shares at any time after December 31, 2025. Once redeemed, the shares are cancelled and extinguished; and they revert to authorized but unissued status.

Upon issuance, the Series F Preferred Stock was not mandatorily redeemable because redemption was subject to Conversion Approval, and eventual redemption is at the option of the holders upon the occurrence of certain events that are not solely within the control of the Company. In accordance with ASC 480-10-S99-3A, although the Series F Preferred Stock is legally designated as equity and is not mandatorily redeemable, it does not meet the requirements for permanent equity classification upon issuance. Accordingly, the Series F Preferred Stock has been presented as mezzanine equity (temporary equity) on the Company’s condensed consolidated balance sheet, between liabilities and stockholders’ equity, at its initial carrying amount of $525,000 which is equivalent to its redemption value. The Company will not accrete the carrying value of the Series F Preferred Stock to its redemption amount since they are equivalent. Upon Conversion Approval (which was obtained subsequent to September 30, 2025 – see Note 19, “Subsequent Events”), the Company will reclassify the Series F Preferred Stock to liability in accordance with ASC 480-10-25-4 as it becomes redeemable at the holder’s option at that time.

Common Stock

See Notes 8, “Financing Activities” and 10, “Common Stock Warrants” for a description of common stock and common stock warrant-related transactions during the three and nine months ended September 30, 2025 and 2024.

Dividends

On August 26, 2025, the Special Transaction Committee of the Board of Director and the Company’s Board of Directors declared a special cash dividend of $0.80 per share for the Company’s common stock (the “Special Dividend”). The dividend totaling $4.8 million was paid on September 29, 2025 to stockholders of record of Common Stock at the close of business on September 15, 2025.

NOTE 12. STOCK-BASED COMPENSATION

Equity Compensation Plans

In October 2007, the Company adopted the 2007 Omnibus Incentive Plan (the “2007 Plan”) to provide for the grant of equity awards, such as stock options, unrestricted and restricted common stock, stock units, dividend equivalent rights, and stock appreciation rights to employees, directors and outside consultants, as determined by the Board. The 2007 Plan expired on March 15, 2017. Upon expiration, new awards cannot be issued pursuant to the 2007 Plan, but outstanding awards continue to be governed by its terms. Stock options granted under the 2007 Plan expire no later than ten years from the date of grant. All stock options outstanding under the 2007 Plan were fully vested as of December 31, 2024.

In March 2017, the Company adopted the 2017 Omnibus Incentive Plan (the “2017 Plan”), which was approved by stockholders on June 2, 2017, to provide for the grant of equity awards, such as nonqualified stock options (“NQSOs”), incentive stock options (“ISOs”), restricted stock, performance shares, stock appreciation rights (“SARs”), RSUs and other share-based awards to employees, directors, and consultants, as determined by the Board. The 2017 Plan does not affect awards previously granted under the 2007 Plan. Upon adoption, the 2017 Plan allowed for awards of up to 66,243 shares of the Company’s common stock, plus an automatic annual increase in the number of shares authorized for awards on the first day of each of the Company’s fiscal years beginning January 1, 2018 through January 1, 2027 equal to (i) 4% of the number of shares of common stock outstanding on the last day of the immediately preceding fiscal year or (ii) such lesser number of shares of common stock as determined by the Board. As of September 30, 2025, there were 14,332 shares available for future awards under the 2017 Plan. Subsequent to September 30, 2025, on October 16, 2025, stockholders approved an amendment to increase the shares authorized under the 2017 Plan by 1,000,000 shares (see Note 19, “Subsequent Events”).

Under the terms of the 2017 Plan, the exercise price of NQSOs, ISOs and SARs may not be less than 100% of the fair market value of the Company’s common stock on the date of grant and, if ISOs are granted to an owner of more than 10% of the Company’s common stock, then not less than 110% of the fair market value of the Company’s common stock on the date of grant. The term of awards will not be longer than ten years or, in the case of ISOs, no longer than five years with respect to holders of more than 10% of the Company’s common stock. Stock options granted to employees generally vest over four years, while options granted to directors and consultants typically vest over a shorter period, subject to continued service. The Company issues new shares of Company common stock to satisfy exercises of options under the 2007 Plan and the 2017 Plan.

Summary of Outstanding Equity Awards

The following table summarizes information about the Company’s stock options and restricted stock outstanding at December 31, 2024, and activity during the nine months ended September 30, 2025:

Vested and exercisable at September 30, 2025 |  |  | 1 |  |  |  | 2,541.07 |  |  |  | 2.9 |  |  |  | — |

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying stock option awards and the closing market price of the Company’s common stock as quoted on the NYSE American as of September 30, 2025 for option awards that have an exercise price that is lower than the market price. There were no stock option awards exercised during the three and nine months ended September 30, 2025 and 2024.

As of September 30, 2025, there was no unrecognized compensation cost related to unvested stock options and restricted stock.

Equity Awards to Employees and Directors

The Company grants options to purchase common stock to its employees and directors at prices equal to or greater than the market value of the stock on the dates the options are granted. The Company has estimated the value of stock option awards as of the date of grant by applying the Black-Scholes option pricing model using the single-option valuation approach. The application of this valuation model involves assumptions that are judgmental and subjective in nature. See Note 2, “Summary of Significant Accounting Policies,” for a description of the accounting policies that the Company applied to value its stock-based awards.

NOTE 14. AVENOVA ASSET DIVESTITURE AND BRIDGE LOAN

On January 17, 2025, the Company completed the sale of its eyecare products sold under the Avenova brand and related assets (the “Avenova Assets”) to PRN Physician Recommended Nutriceuticals, LLC, a Delaware limited liability company (“PRN”), which constituted substantially all of the Company’s revenue generating and operating assets (the “Avenova Asset Divestiture”). The Avenova Asset Divestiture was consummated pursuant to the Asset Purchase Agreement, dated September 19, 2024, as amended by Amendment No. 1 to the Asset Purchase Agreement, dated November 5, 2024 (as so amended, the “Purchase Agreement”). The Purchase Agreement provided for, among other terms, a base purchase price of $11.5 million for the Avenova Assets and for PRN to provide the Company with up to a $1.0 million secured promissory note (the “Bridge Loan”). Amounts borrowed under the Bridge Loan were required to be used for working capital purposes, bore interest at a rate of 10% per annum and were secured by all of the Company’s assets as collateral. On November 22, 2024, the Company requested and received $0.5 million under the Bridge Loan.

In accordance with the Purchase Agreement, at the closing of the Avenova Asset Divestiture the Company received the cash purchase price equal to $11.5 million, less (i) the $507,954 balance of the Bridge Loan which was discharged with collateral released and (ii) $500,000, which amount was deposited into an escrow account (the “Escrow”) for up to six (6) months to be used for the Company’s indemnification obligations under the Purchase Agreement or the payment of the Net Working Capital Adjustment (as defined below) after the closing. The final amount of the purchase price that the Company received in the Avenova Asset Divestiture was subject to a post-closing working capital adjustment, upward or downward, that was limited to an amount of up to $500,000 (the “Net Working Capital Adjustment”). The Net Working Capital Adjustment was mutually determined by PRN and the Company based upon the difference between the amount of the Company’s Net Working Capital (as defined in the Purchase Agreement) immediately prior to the closing and the agreed upon target working capital value of $800,000. The Net Working Capital Adjustment was determined to be $365,566, which reduced the amount of total proceeds that we received from the Avenova Asset Divestiture. The Company recorded a gain of $10.7 million on the Avenova Asset Divestiture during the quarter ended March 31, 2025, net of the agreed upon Net Working Capital Adjustment.

In connection with the closing of the Avenova Asset Divestiture on January 17, 2025, the Company entered into a Transition Services Agreement, dated January 17, 2025 with PRN, pursuant to which the Company agreed to provide services to PRN with respect to specified accounting, marketing, sales, customer service, regulatory and operational support for a period of four (4) months after the closing of the Avenova Asset Divestiture (the “PRN Transition Services Agreement”). In exchange for providing such services, PRN and the Company agreed upon service fees to be paid to the Company.

ITEM 2. | MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This discussion contains forward-looking statements that involve risks and uncertainties. The following discussion of our financial condition and results of operations should be read together with our unaudited condensed consolidated financial statements and related notes included in Part I, Item 1 of this report, and with our consolidated financial statements and related notes, and Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in our 2024 Annual Report. Words such as “expects,” “anticipated,” “will,” “may,” “goals,” “plans,” “believes,” “estimates,” “concludes,” “determines,” variations of these words, and similar expressions are intended to identify these forward-looking statements. As a result of the significant changes that have occurred to us and our business as a result of completing the Avenova Asset Divestiture and the PhaseOne Divestiture, the 2025 Preferred Stock Issuance and the sale of the October 2025 Pre-Funded Warrants, the expected additional changes that will occur when we determine and proceed with the future strategic direction of our Company, as well as other factors, including those set forth under the section titled “Risk Factors” in Part I, Item 1A. of this Quarterly Report and the section titled “Risk Factors” in Part I, Item 1A. of our 2024 Annual Report, as well as in other sections in our SEC filings, our actual results may differ materially from those anticipated in these forward-looking statements. Readers are cautioned that these forward-looking statements are only predictions based upon assumptions made that we believed to be reasonable at the time and are subject to risks and uncertainties. Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. Except as required by law, we undertake no obligation to revise or update publicly any forward-looking statements after the date of this report, even if new information becomes available in the future.

Overview

We were previously focused on the development and sale of eyecare, wound care, and skin care products. The Company may continue to manufacture wound care products domestically in the United States and export finished goods to China.

| ● | The Avenova Asset Divestiture closed on January 17, 2025 in which we sold our primary eyecare business (see Note 14, “Avenova Asset Divestiture and Bridge Loan” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report);
| ● | The PhaseOne Divestiture closed on January 8, 2025 in which we sold our PhaseOne trademark (see Note 15, “PhaseOne Divestiture” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report); and
| ● | The DERMAdoctor Divestiture closed on March 12, 2024 in which we sold our primary skin care business (see Note 16, “DERMAdoctor Divestiture” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report).

Discontinued Operations

Historical financial results related to each of the businesses that we divested above in the Avenova Asset Divestiture, the PhaseOne Divestiture and the DERMAdoctor Divestiture are presented as discontinued operations in the unaudited condensed consolidated financial statements included in this report. See Notes 14, “Avenova Asset Divestiture and Bridge Loan,” 15 “PhaseOne Divestiture” and 16, “DERMAdoctor Divestiture” to the Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report for additional details.

Previous Plan of Dissolution and Strategic Direction of the Company

The Company’s Board unanimously approved each of the divestitures above and subsequently evaluated additional strategic options available to the Company. During this time, the Board pursued the Dissolution pursuant to Plan of Dissolution which was approved at the 2025 Special Meeting (see Note 1, “Organization” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report). Although stockholder approval of the Dissolution was received, the Board was authorized to subsequently determine, in its discretion, whether or not to proceed with the Dissolution. The Board ultimately determined not to pursue the Dissolution and simultaneously entered into the 2025 Preferred Stock Purchase Agreement (see Note 8, “Financing Activities” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report), Series E Preferred Stock Closing (see Note 19, “Subsequent Events” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report) and October 2025 Pre-Funded Warrants (see Note 19, “Subsequent Events” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report). As part of its broader capital allocation review, the Company has begun evaluating opportunities within emerging financial infrastructure and network-based markets. These opportunities may include select blockchain-based assets that the Company believes could enhance capital efficiency and long-term stockholder value.

NYSE American Notices

On April 18, 2024, the Company received a notification from the NYSE American LLC Exchange (“NYSE American”) stating that the Company is not in compliance with Section 1003(a)(i), 1003(a)(ii) and 1003(a)(iii) of the NYSE American Company Guide (requiring stockholders’ equity of (i) $2.0 million or more if the Company has reported losses from continuing operations and/or net losses in two of its three most recent fiscal years; (ii) $4.0 million or more if the Company has reported losses from continuing operations and/or net losses in three of the four most recent fiscal years and (iii) $6.0 million or more if the Company has reported losses from continuing operations and/or net losses in its five most recent fiscal years, respectively.

Table of Contents

On October 20, 2025, the Company was notified by NYSE American that the Company had regained compliance with the minimum stockholders’ equity requirements of Sections 1003(a)(i), 1003(a)(ii) and 1003(a)(iii) of the Company Guide.

Financial Overview and Outlook

Based on our funds available on September 30, 2025, together with net proceeds from the issuance of the Series E Preferred Stock and October 2025 Pre-Funded Warrants (see Note 19, “Subsequent Events” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report), management believes that the Company’s existing cash and cash equivalents will be sufficient to enable the Company to meet its planned operating expenses at least through November 7, 2026; however, as referenced above, the Company is considering adjustments to its strategic direction. As a result of any changes in the Company’s strategic direction, there may be circumstances that cause the Company to adjust its anticipated spending in the near term.

Critical Accounting Estimates

Our unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP. The preparation of these unaudited condensed consolidated financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, as well as the reported revenues and expenses during the reporting periods. In preparing these unaudited condensed consolidated financial statements, management has made its best estimates and judgments of certain amounts, giving due consideration to materiality. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances. Actual results may differ from these estimates.

While our significant accounting policies are more fully described in Note 2, “Summary of Significant Accounting Policies” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report, we believe that the following accounting estimates are most critical to fully understanding and evaluating our reported financial results as discussed in this Management’s Discussion and Analysis of Financial Condition and Results of Operations, particularly taking into account the significant changes that occurred to our business as a result of the closing of the Avenova Asset Divestiture and the PhaseOne Divestiture in January 2025.

Impairment of Assets

We review long-lived assets for impairment at least annually or whenever events or changes in business circumstances indicate that any such asset may be impaired, that the carrying amount of any such asset may not be fully recoverable or that the useful life of the asset, if applicable, is no longer appropriate. Management uses judgement in making critical assumptions and estimates in determining when an impairment assessment should be recorded, if more frequent than annually, or in the completion of any such assessment. This includes cash flow projections that look several years into the future and assumptions on variables such as economic conditions, probability of success, and discount rates. Changes in judgments with respect to these assumptions and estimates could impact any such impairments recorded such as those recorded in the first and third quarter of 2025 as further described in Notes 2, “Summary of Significant Accounting Policies;” 5, “Property and Equipment;” and 7, “Commitments and Contingencies” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report.

Common Stock Warrant Liabilities

For warrants that are classified as liabilities, the Company records the fair value of the warrants upon issuance and at each balance sheet date with changes in the estimated fair value recorded as a non-cash gain or loss in the unaudited condensed consolidated statements of operations. The fair values of these warrants are determined using the Black Scholes option pricing model. These values are subject to a significant degree of management’s judgment.

Impact of Divestitures

See additional information in Notes 14, “Avenova Asset Divestiture and Bridge Loan;” and 15, “PhaseOne Divestiture;” in Notes to the Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report for additional details regarding these financial results for the periods presented. The discussions below and throughout this section apply only to results from our continuing operations except as otherwise noted.

Total Net Sales and Cost of Goods Sold

Product revenue, net, increased $0.5 million, or 100%, to $0.5 million for the three months ended September 30, 2025.

Revenue and cost of goods sold recorded during the three months ended September 30, 2025 was from the Company’s wound care business sold to our Chinese distributor with no comparable order in the three months ended September 30, 2024.

General and administrative

General and administrative expenses decreased $0.5 million, or 29%, to $1.2 million for the three months ended September 30, 2025, from $1.7 million for the three months ended September 30, 2024, due primarily to a decrease in outside services costs related to non-recurring strategic initiatives, including the Avenova Asset Divestiture, the PhaseOne Divestiture, and evaluating and pursuing various strategic options for our Company.

Impairment of Long-Lived Assets

Impact of Divestitures

Financial results related to divested assets from the Avenova Asset Divestiture and the PhaseOne Divestiture for the nine months ended September 30, 2025 and from the DERMAdoctor Divestiture for the nine months ended September 30, 2024 have been aggregated and reported for each of these periods in the line item titled “Net income from discontinued operations, net of taxes” in the table above. See additional information in Notes 14, “Avenova Asset Divestiture and Bridge Loan;” 15, “PhaseOne Divestiture;” and 16, “DERMAdoctor Divestiture” in Notes to the Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report for additional details regarding these financial results for the periods presented. The discussions below and throughout this section apply only to results from our continuing operations except as otherwise noted.

Total Net Sales and Cost of Goods Sold

Product revenue, net, increased $0.5 million, or 100%, to $0.5 million for the nine months ended September 30, 2025.

Revenue and cost of goods sold recorded during the nine months ended September 30, 2025 was from the Company’s wound care business sold to our Chinese distributor with no comparable order in the nine months ended September 30, 2024.

General and administrative

General and administrative expenses increased $0.2 million, or 3%, to $5.8 million for the nine months ended September 30, 2025, from $5.6 million for the nine months ended September 30, 2024, due primarily to an increase in outside services costs related to non-recurring strategic initiatives, including evaluating and pursuing various strategic options for our Company.

Impairment of Long-Lived Assets

During the nine months ended September 30, 2025, the Company recorded an impairment for right-of-use assets associated with leases of $643 thousand and $33 thousand for fixed assets including leasehold improvements.

Non-cash gain on changes in fair value of warrant liability

Adjustments to the fair value of warrant liabilities resulted in a gain of $0.1 million for the nine months ended September 30, 2024 with no comparable adjustment for the nine months ended September 30, 2025. For additional information regarding warrant liabilities and their valuation, please see Note 3, “Fair Value Measurements” and Note 10, “Common Stock Warrants” in the Notes to Unaudited Condensed Consolidated Financial Statements, (unaudited) in Part I, Item 1 of this report.

Non-cash loss on changes in fair value of embedded derivative liability

Adjustments to the fair value of embedded derivative liability resulted in a loss of $18 thousand for the nine months ended September 30, 2024 with no comparable adjustment for the nine months ended September 30, 2025. For additional information regarding the embedded derivative liability and its valuation, please see Note 3, “Fair Value Measurements” and Note 9, “Convertible Notes” in the Notes to the Condensed Consolidated Financial Statements (unaudited), in Part I, Item 1 of this report.

Accretion of interest and amortization of discounts on convertible notes

Accretion of interest and amortization of discounts on convertible notes was $0.9 million for the nine months ended September 30, 2024 with no comparable result for the nine months ended September 30, 2025. The 2024 result was primarily from the amortization of discount and issuance cost related to the Secured Convertible Notes issued in May 2023 which were fully repaid in the third quarter of 2024. See Note 3, “Fair Value Measurements” and Note 9, “Convertible Notes” in the Notes to the Condensed Consolidated Financial Statements (unaudited), in Part I, Item 1 of this report.

Other expense, net

Other expense, net was $190 thousand for the nine months ended September 30, 2025 and $0.5 million for the nine months ended September 30, 2024. The higher result in the 2024 period was due to issuance costs incurred for the March 2024 Warrant and the Unsecured Convertible Notes issued in March 2024. See Note 9, “Convertible Notes” and Note 10, “Common Stock Warrants” in the Notes to the Condensed Consolidated Financial Statements (unaudited), in Part I, Item 1 of this report.

Financial Condition, Liquidity and Capital Resources

We have largely incurred net losses and generated negative cash flows from operations since inception and may incur losses as we pursue our new strategic direction. As of September 30, 2025, our cash and cash equivalents were $2.3 million, compared to $430 thousand as of December 31, 2024. Based on our funds available on September 30, 2025, together with net proceeds from the issuance of the Series E Preferred Stock and October 2025 Pre-Funded Warrants (see Note 19, “Subsequent Events” in the Notes to Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report), management believes that the Company’s existing cash and cash equivalents will be sufficient to enable the Company to meet its planned operating expenses at least through November 7, 2026; however, as referenced above, the Company is considering adjustments to its strategic direction. As a result of any changes in the Company’s strategic direction, there may be circumstances that cause the Company to adjust its anticipated spending in the near term.

Net Cash Used in Operating Activities, Continuing Operations

Net cash used in operating activities from continuing operations was $6.2 million for the nine months ended September 30, 2025, which consisted primarily of a net loss from continuing operations of $6.6 million, adjusted by depreciation and amortization expenses of $5 thousand, stock-based compensation expenses related to employee and director stock awards of $6 thousand, non-cash right-of-use asset amortization of $0.1 million, non-cash impairment of long-lived assets of $0.7 million, accretion of interest and amortization of debt discounts on convertibles notes of $84 thousand, and a net increase of $0.4 million in our net operating assets and liabilities of continuing operations.

Net cash used in operating activities from continuing operations was $5.8 million for the nine months ended September 30, 2024, which consisted primarily of a net loss from continuing operations of $6.0 million, adjusted by depreciation and amortization expenses of $24 thousand, stock-based compensation expenses related to employee and director stock awards of $0.1 million, non-cash expense incurred to obtain consent of Secured Convertible Note holders in connection with the DERMAdoctor Divestiture of $0.4 million, non-cash gain on changes in fair value of warrant liability of $0.1 million, non-cash loss on changes in fair value of embedded derivative liability of $18 thousand, non-cash loss on modification of warrants of $69 thousand, non-cash right-of-use asset amortization of $254 thousand, accretion of interest and amortization of debt discounts on convertibles notes of $0.9 million, and a net increase of $0.6 million in our net operating assets and liabilities of continuing operations.

Cash Used in Investing Activities, Continuing Operations

Net cash used in investing activities from continuing operations was $2 thousand for the nine months ended September 30, 2024, which consisted of purchases of property and equipment. There was no cash used in, or provided by, investing activities from continuing operations during the nine months ended September 30, 2025.

Cash Used in Financing Activities, Continuing Operations

Net cash used in financing activities from continuing operations was $3.2 million for the nine months ended September 30, 2025, which consisted primarily of $2.0 million in cash payments to repurchase outstanding warrants, a $0.5 million repayment of the Bridge Note, and dividend paid of $4.8 million. Offsetting these payments were $0.9 million in proceeds from warrant exercises and $3.8 million in proceeds from the Lazar Purchase Agreement.

Table of Contents

Net cash provided by financing activities from continuing operations was $1.0 million for the nine months ended September 30, 2024,

which included repayment of $2.0 million for the Secured Convertible Notes through September 30, 2024, net proceeds of $2.9 million from the 2024 Public Offering transaction, and the net proceeds of $0.2 million from the 2024 Warrant Repice transaction.

Net Operating Losses and Tax Credit Carryforwards

As of December 31, 2024, we had net operating loss carryforwards for federal and state income tax purposes of $153.7 million and $128.6 million, respectively. The federal net operating loss carryforwards consist of $94.9 million generated before January 1, 2018, which will begin to expire in 2025 and $59.6 million generated after December 31, 2017, that will carry forward indefinitely but are subject to an 80% limitation for years following December 31, 2021. The state net operating loss carryforwards will begin to expire in 2028. As of December 31, 2024, we also had tax credit carryforwards of $0.5 million for federal income tax purposes and $0.1 million for state tax purposes. If not utilized, the federal tax credits will begin expiring in 2031. The state tax credits have an indefinite carryover period.

Current federal and California tax laws include substantial restrictions on the utilization of net operating loss carryforwards in the event of an ownership change of a corporation. Accordingly, our ability to utilize net operating loss carryforwards may be limited as a result of such ownership changes. Such a limitation could result in the expiration of carryforwards before they are utilized.

Inflation

Our costs and operating expenses are subject to fluctuations, particularly historically due to changes in the cost of labor and service providers. As a result of our recent changes to our business and reduced operations, our future business results will depend, in part, on our continued ability to manage these fluctuations through cost savings projects and sourcing decisions. Failure to manage these fluctuations could adversely impact our results of operations or cash flows.

Off-Balance Sheet Arrangements

We did not have any “off-balance sheet arrangements” as defined in Item 303(b)(1)(ii)(B) of Regulation S-K at September 30, 2025 or December 31, 2024.

Seasonality

Our NeutroPhase branded product is sold through our distribution partner in China; therefore, we receive periodic large orders that result in large chunks of revenue that are received in irregular intervals.

Contractual Obligations

In the normal course of business, we have historically entered into contracts and commitments that obligate us to make payments in the future and we expect to enter into contracts and commitments on behalf of the Company in connection with our evolving strategic direction. Information regarding our obligations under lease and convertible note arrangements are provided in Notes 7 and 9, respectively, in the Notes to the Condensed Consolidated Financial Statements (unaudited) in Part I, Item 1 of this report.

ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our market risk consists principally of interest rate risk on our cash and cash equivalents. Our exposure to market risk is limited primarily to interest income sensitivity, which is affected by changes in interest rates, particularly because our current liquid assets at September 30, 2025 were held in cash and cash equivalents.

Our investment policy restricts our investments to high-quality investments and limits the amounts invested with any one issuer, industry, or geographic area. The goals of our investment policy are as follows: preservation of capital, assurance of liquidity needs, best available return on invested capital, and minimization of capital taxation. Some of the securities in which we invest may be subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. For example, if we hold a security that was issued with an interest rate fixed at the then-prevailing rate and the prevailing interest rate later rises, the principal amount of our investment will probably decline. To minimize this risk, in accordance with our investment policy, we maintain our cash and cash equivalents in short-term marketable securities, including money market mutual funds, Treasury bills, Treasury notes, certificates of deposit, commercial paper, and corporate and municipal bonds. The risk associated with fluctuating interest rates is limited to our investment portfolio. Due to the short-term nature of our investment portfolio, we believe we have minimal interest rate risk arising from our investments. As of September 30, 2025 and December 31, 2024, a 10% change in interest rates would have had an immaterial effect on the value of our investment portfolio. We do not use derivative financial instruments in our investment portfolio. We do not hold any instruments for trading purposes.

With most of our focus on the domestic U.S. market, we have not had any material exposure to foreign currency rate fluctuations.

ITEM 4. | CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 and 15d-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Assessing the costs and benefits of such controls and procedures necessarily involves the exercise of judgment by management. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.

Based upon that evaluation at September 30, 2025, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective to ensure, at the reasonable assurance level, that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and were effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Exchange Act was accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the current quarter which has materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. | LEGAL PROCEEDINGS

From time to time, the Company may be involved in various legal proceedings arising in the ordinary course of business. As of September 30, 2025, there were no matters that, in the opinion of management, would ultimately result in liability that would have a material adverse effect on the Company’s financial position, results of operations or cash flows.

ITEM 1A. | RISK FACTORS

For information regarding factors that could affect our business, results of operations, financial condition and liquidity, see the risk factors discussed under Part I, Item 1A included in our 2024 Annual Report.

The Company is supplementing the risk factors previously disclosed in our 2024 Annual Report with the following risk factors.

Risks Related to Our Proposed Strategy Focusing on Assets Within Emerging Decentralized Financial Infrastructure and Network-Based Markets

We are considering shifting a portion of our business strategy by evaluating opportunities within emerging decentralized financial infrastructure and network-based markets, which may include select blockchain based assets and we may be unable to successfully implement this new strategy.

We are considering shifting a portion of our business strategy by evaluating opportunities within emerging decentralized financial infrastructure and network-based markets, which may include select blockchain-based assets, including through staking, restaking, liquid staking and other decentralized finance activities. The Company’s review of such opportunities is preliminary in nature, and there can be no assurance that any particular transaction, investment, or strategic initiative will be pursued or consummated. These evaluations remain subject to ongoing diligence, market conditions, regulatory considerations, and approval by the Board, as appropriate. Any potential activity in this area would be conducted in a manner consistent with the Company’s existing compliance framework and applicable laws and regulations. This strategic shift would require specialized employee skillsets and operational, technical and compliance infrastructure to support stablecoin and related staking activities. This would also require that we implement different security protocols and treasury management practices. Further, there is ongoing scrutiny and limited formal guidance from regulatory agencies, including NYSE and the SEC, with respect to the treatment of similar strategies from other public companies. There is no assurance that we will be able to execute this strategy by building out the needed infrastructure within the timeframe that we currently anticipate. Errors by key management could result in significant loss of funds and reduced rewards. As a result, our shift towards blockchain-based assets could have a material adverse effect on our business and financial condition.

Our potential shift towards a business strategy focused on emerging decentralized financial infrastructure and blockchain-based assets would require substantial changes in our day-to-day operations and exposes us to significant operational risks.

Our potential shift towards a strategy focused on emerging decentralized financial infrastructure and blockchain-based assets, including staking, restaking, liquid staking, and other decentralized finance activities, exposes us to significant operational risks. They may also require that we maintain constant up time to ensure that we are eligible for staking rewards and to avoid penalties. In addition, the decentralized financial infrastructure and network-based markets ecosystem rapidly evolves, with frequent upgrades and protocol changes that may require significant adjustments to our operational setup. The upgrades and protocol changes may require that we incur unanticipated costs. We may also need to employ third-party service providers in our operations, which may introduce risks outside of our control, including significant cybersecurity risks. Any of these operational risks could materially and adversely affect our ability to execute our strategy, prevent us from realizing positive returns and severely hurt our financial condition.

Adverse changes in the regulatory treatment of blockchain-based assets could materially impair the value and liquidity of our future holdings and negatively impact our business, financial condition, and results of operations going forward.

The legal and regulatory framework governing blockchain-based assets in the United States and in foreign jurisdictions is rapidly evolving and remains highly uncertain. Federal, state, and foreign regulators continue to issue new rules and take enforcement actions that directly or indirectly affect the classification, transferability, custody, and tax treatment of blockchain-based assets. Should any such asset we purchase, or the activities of any party critical to the blockchain ecosystem (including exchanges, validators, or custodians), be deemed to violate securities, commodities, anti-money-laundering, sanctions, consumer-protection, or other applicable laws, we could become subject to significant fines, penalties, registration requirements, trading restrictions, or forced divestiture of such blockchain-based assets. Any such development could cause a precipitous decline in the market price of such assets, impair our ability to monetize or otherwise use our blockchain-based asset treasury, and adversely impact the market price of our securities.

Risks Related to Blockchain-Based Assets

The blockchain-based asset trading platforms on which assets within emerging financial infrastructure and network-based markets trade are relatively new and largely unregulated or may not be complying with existing regulations.

The blockchain-based assets that we are evaluating primarily trade on blockchain-based asset trading platforms and decentralized finance protocols which are relatively new and, in many ways, are not subject to, or may not comply with, regulation in relevant jurisdictions in a manner similar to other regulated trading platforms, such as national securities exchanges or designated contract markets. While many of these relatively new trading platforms provide the public with information regarding their ownership structure, management teams, private key management, hot/cold storage policies, on-chain activities, capitalization, corporate practices and regulatory compliance, many other relatively new trading platforms do not. In particular, those located outside the United States may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions.

The trading platforms on which the blockchain-based assets that we are evaluating trade may be unpredictable and susceptible to attacks.

Significant trading may occur on systems and platforms with minimum predictability. Spot markets may impose daily, weekly, monthly or customer-specific transaction or withdrawal limits or suspend withdrawals entirely, rendering the exchange of blockchain-based assets for fiat currency difficult or impossible. Further, participation in spot markets requires users to take on credit risk by transferring blockchain-based assets from a personal account to a third-party’s account.

Additionally, tools to detect and deter fraudulent or manipulative trading activities (such as market manipulation, front-running of trades, and wash-trading) may not be available to or employed by such trading platforms or may not exist at all. As a result, the marketplace may lose confidence in, or may experience problems relating to, these venues and the blockchain-based assets that trade on these venues. No trading platform on which blockchain-based assets trade is immune from these risks. The closure or temporary shutdown of such trading platforms due to fraud, business failure, hackers or malware, or government-mandated regulation may reduce confidence in blockchain-based assets and other assets within emerging financial infrastructure and network-based markets and can slow down the mass adoption of it. Further, trading platform failures can have an adverse effect on blockchain-based markets and the price of blockchain-based assets and could therefore have a negative impact on the performance of our Common Stock.

The trading prices of many blockchain-based assets have experienced extreme volatility in recent periods and may continue to do so. Extreme volatility in the future, including further declines in trading prices, could have a material adverse effect on the value of our common stock and the common stock could lose all or substantially all of its value.

The trading prices of many blockchain-based assets have experienced extreme volatility in recent periods and may continue to do so. For instance, there were steep increases in the value of certain blockchain-based assets over the course of 2021, and multiple market observers asserted that blockchain-based assets were experiencing a “bubble.” These increases were followed by steep drawdowns throughout 2022. Prices of such blockchain-based assets continued to fluctuate widely throughout 2023 and through this date.

Extreme volatility in the future could have a material adverse effect on the value of our common stock and our common stock could lose all or substantially all of its value. Furthermore, negative perception and a lack of stability and standardized regulation in the blockchain-based economy may reduce confidence in the blockchain-based economy and may result in greater volatility in the price of blockchain-based assets, including a depreciation in value.

ITEM 2. | UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

2025 Preferred Stock Purchase Agreement

On August 19, 2025, the Company entered into 2025 Preferred Stock Purchase Agreement with David E. Lazar, that provides for the Company to sell in a private placement (i) an aggregate of 481,250 shares of Series D Preferred Stock convertible into an aggregate of 77.0 million shares of Common Stock for $3.85 million and (ii) an aggregate of 268,750 shares of Series E Preferred Stock convertible into an aggregate of 43.0 million shares of Common Stock for an additional $2.15 million.

Simultaneous to entering into the 2025 Preferred Stock Purchase Agreement on August 19, 2025, Mr. Lazar completed the Initial Series D Preferred Purchase. The 2025 Preferred Stock Purchase Agreement provided for the ability of Mr. Lazar to assign, transfer and/or sell his shares of Series D Preferred Stock, Series E Preferred Stock, and/or his right acquire such securities. As further described in Note 19, “Subsequent Events”, on October 9, 2025, Mr. Lazar entered into an agreement to effect such transfer.

Since the Common Stock is currently listed on the NYSE American, and among these requirements are Section 713(a) and (b) of the Company Guide. Section 713(a) of the Company Guide requires stockholder approval in connection with any transaction, other than a public offering, involving the sale, issuance, or potential issuance, of common stock or securities convertible into common stock, equal to 20.0% or more of presently outstanding stock for less than the greater of book or market value. Section 713(b) of the Company Guide requires stockholder approval of a transaction, other than a public offering, involving the sale, issuance or potential issuance by an issuer of common stock (or securities convertible into, or exercisable for, common stock) when the issuance or potential issuance of additional shares may result in a change of control of the issuer. As a result of the significant number of shares of Common Stock that may be issued upon the future conversion of the Series D Preferred Stock and Series E Preferred Stock compared to the currently issued and outstanding shares of Common Stock as provided above, the Company was required to obtain stockholder approval in accordance with the Company Guide Rule 713(a) and Rule 713(b) for Conversion Approval.

Conversion Approval was obtained subsequent to September 30, 2025, on October 16, 2025.

Table of Contents

On October 16, 2025, subsequent to September 30, 2025 and the Conversion Approval, the Company completed the sale of 268,750 shares of Series E Preferred Stock at a price of $8.00 per share for aggregate gross proceeds of $2.15 million.

Series E Preferred Stock Closing

The 2025 Preferred Stock Purchase Agreement dated as of August 19, 2025 between the Company and Mr. Lazar provided for the ability of Mr. Lazar to assign, transfer and/or sell his shares of Series D Preferred Stock, Series E Preferred Stock, the shares of Common Stock underlying the Transferred Stock and/or his right acquire such securities (see Note 8, “Financing Activities”). On October 9, 2025, Mr. Lazar tendered his resignation as Chief Executive Officer and a director of NovaBay and entered into a securities purchase agreement with the Purchasers to effect such transfer. Pursuant to the agreement, Mr. Lazar agreed to assign to the Purchasers all of the Seller’s right, title and interest in (i) 441,326 outstanding shares of Series D Preferred Stock and (ii) the rights and obligations to purchase the Transferred Stock and the transactions contemplated by the Lazar Sale, each of which were purchased from the Company by Mr. Lazar pursuant to the 2025 Preferred Stock Purchase Agreement. On October 16, 2025, pursuant to the 2025 Preferred Stock Purchase Agreement, the Company filed the certificate of designations relating to the 2025 Preferred Stock Issuance. Each share of Series E Preferred Stock shall convert at the option of the holder or, otherwise, shall automatically convert 30 business days after the Stockholder Approval, into 160 shares of Common Stock, for an aggregate of 43,000,000 shares of Common Stock.

October 2025 Pre-Funded Warrants

On October 16, 2025, the Company issued and sold the October 2025 Pre-Funded Warrants to purchase an aggregate of 5,405,406 shares of Common Stock, to the Purchasers in two transactions for aggregate gross proceeds of approximately $6.0 million The purchase price was $1.10 per October 2025 Pre-Funded Warrant, representing 110% of the closing price of the Common Stock on the day before the issuance, less the $0.01 exercise price for each such October 2025 Pre-Funded Warrant. The October 2025 Pre-Funded Warrants are exercisable for shares of Common Stock at any time after January 1, 2026, subject to receipt of stockholder approval.
