SANUWAVE HEALTH, INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2025
1. Nature of the Business and Basis of Presentation
SANUWAVE Health, Inc. and subsidiaries (“SANUWAVE” or the “Company”) is focused on the commercialization of its patented regenerative medicine utilizing noninvasive ultrasound or shockwaves to produce a biological response promoting the repair and regeneration of tissue, musculoskeletal, and vascular structures.
Basis of Presentation - The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8-03 of Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all the information and disclosures required by U.S. GAAP for comprehensive financial statements.
The financial information as of September 30, 2025, and for the three and nine months ended September 30, 2025, and 2024 is unaudited; however, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2025, are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2025.
The condensed consolidated balance sheet on December 31, 2024, has been derived from the audited consolidated financial statements at that date but does not include all the information and disclosures required by U.S. GAAP for comprehensive financial statements. These condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on March 20, 2025 (the “2024 Annual Report”).
Reverse Stock Split - All share numbers, including the number of shares underlying warrants, options and convertible debt, and per share amounts presented in these condensed consolidated financial statements, including these footnotes, reflect a one-for-three hundred seventy five (1:375) reverse stock split of the outstanding shares of the Company's common stock effected on October 18, 2024 (the "Reverse Stock Split"). The Company's authorized shares of common and preferred stock along with the par value did not change as a result of the Reverse Stock Split, and no fractional shares were issued as a result of the Reverse Stock Split. Any fractional shares that would have resulted from the Reverse Stock Split were settled in cash. The Reverse Stock Split affected all common stockholders uniformly and did not alter any stockholder's percentage interest in the Company's common stock, except to the extent that the Reverse Stock Split resulted in certain stockholders experiencing an adjustment of a fractional share as described above.
Reclassification - Certain accounts in the prior period condensed consolidated balance sheets and statement of cash flows have been reclassified to conform to the presentation of the current period condensed consolidated financial statements. These reclassifications had no effect on the previously reported operating results.
2. Going Concern
The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. In prior periods, the Company experienced recurring net losses, accumulated deficits, negative working capital, and significant debt maturities, which raised substantial doubt about its ability to continue as a going concern.
During the third quarter of 2025, management executed a comprehensive debt refinancing with a new lender, which extended the maturity of the Company’s principal debt obligations from the secured term loan and provided the option for additional liquidity to support ongoing operations through a s ecured revolving credit facility . In addition, the Company achieved positive operating income for the three and nine months ended September 30, 2025, and prior fiscal year ended December 31, 2024, reflecting the impact of strategic initiatives focused on revenue growth and operational efficiency.
As a result of these actions, management has evaluated the Company’s financial condition and cash flow requirements for the twelve months following the issuance of these condensed consolidated financial statements. Based on the debt refinancing, the achievement of operating income, and cash inflow from forecasted operations for at least the next 12
10
months, management believes the Company has sufficient resources to meet its obligations as they become due and to continue its operations for the foreseeable future. Accordingly, when considering all conditions and factors, management has concluded that the substantial doubt about the Company’s ability to continue as a going concern for at least twelve months from issuance of these condensed consolidated financial statements has been alleviated.
Management will continue to monitor the Company’s financial position, operating results, and compliance with debt covenants.
3. Summary of Significant Accounting Policies
Significant accounting policies followed by the Company are summarized below and should be read in conjunction with those described in Note 3 of the consolidated financial statements in our 2024 Annual Report.
Estimates – These condensed consolidated financial statements have been prepared in accordance with U.S. GAAP. Because a precise determination of assets and liabilities, and correspondingly revenues and expenses, depend on future events, the preparation of condensed consolidated financial statements for any period necessarily involves the use of estimates and assumptions. Actual amounts may differ from these estimates. These condensed consolidated financial statements have, in management’s opinion, been properly prepared within reasonable limits of materiality and within the framework of the accounting policies summarized herein.
Significant estimates include the recording of allowances for credit losses, the net realizable value of inventory, fair value of goodwill and other intangible assets, the determination of the valuation allowances for deferred taxes, litigation contingencies, stock-based compensation, incremental borrowing rate, and the estimated fair value of financial instruments, including warrants.
Revenue Recognition - The core principle of Accounting Standards Codification (“ASC”) Topic 606 “Revenue from Contracts with Customers” (“ASC 606”) requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company allocates the transaction price to all contractual performance obligations included in the contract. If a contract has more than one performance obligation, we allocate the transaction price to each performance obligation based on standalone selling price, which depicts the amount of consideration we expect to be entitled in exchange for satisfying each performance obligation. The Company recognizes revenue primarily from the following types of contracts:
System Sales, Consumables and Part Sales - System sales, consumables and part sales include devices and applicators (new and refurbished). Performance obligations are satisfied at the point in time when the customer obtains control of the goods, which is generally at the point in time that the product is shipped.
Licensing Fees - Licensing transactions include distribution licenses and intellectual property licenses. Licensing revenue is recognized as the Company satisfies its performance obligations, which may vary with the terms of the licensing agreement.
Other Revenue - Other revenue primarily includes warranties, repairs, and billed freight. The Company allocates the device sales price to the product and the embedded warranty by reference to the stand alone extended warranty price. Warranty revenue is recognized over the time that the Company satisfies its performance obligations, which is generally the warranty term. Repairs (parts and labor) and billed freight revenue are recognized at the point in time that the service is performed, or the product is shipped, respectively.

Stock-based compensation - The Company accounts for stock-based compensation in accordance with ASC Topic 718, “Compensation—Stock Compensation”. Stock-based compensation expense is recognized for all share-based payment awards based on the grant-date fair value. The Company grants the following types of equity awards:
Time-based or service awards , which vest based on continued service over a specified period. These awards are valued using the Black-Scholes option pricing model (for stock options) or the grant-date fair value of the underlying common stock (for restricted stock units).
Performance-based awards , which vest upon the achievement of pre-established internal performance targets. These awards are valued using the Black-Scholes option pricing model.
11
Market-based awards , which vest upon the attainment of defined market conditions, such as stock price milestones. These awards are valued using a Monte Carlo simulation model.
The Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period for time-based awards, on a straight-line basis over the requisite service period for performance-based awards when it is probable that the associated performance condition will be satisfied, and on a straight-line basis over the requisite service period for market-based awards irrespective of likelihood that the associated market condition will be satisfied. Forfeitures are recognized as they occur. Compensation expense is included in the same functional expense categories as the related employee payroll costs.
Leases
The Company accounts for leases in accordance with ASC Topic 842, "Leases". At the commencement date of a lease, the Company recognizes a right-of-use (“ROU”) asset and a lease liability for all leases with a term greater than 12 months. Short-term leases (those with an original term of 12 months or less) are not recorded on the balance sheet; lease expense for these is recognized on a straight-line basis over the lease term.

Lease liabilities are measured at the present value of future lease payments using the Company’s incremental borrowing rate unless the implicit rate is readily determinable. ROU assets are measured at the initial lease liability, adjusted for lease incentives, initial direct costs, and any prepaid or accrued lease payments.

Lease Incentives

Lease incentives received from lessors, such as rent-free periods or reimbursement for leasehold improvements, are recognized as a reduction to the ROU asset at lease commencement. These incentives are amortized on a straight-line basis over the lease term, consistent with the amortization of the ROU asset. Incentives that are paid directly to the Company or on its behalf are included in the measurement of the ROU asset and reduce the total lease cost recognized over the lease term.
New accounting pronouncements
ASU 2024-03, Disaggregation of Income Statement Expenses
In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures to improve the disclosures about a public entity’s expenses and provide more detailed information about the types of expenses in commonly presented expense captions such as inventory purchases, employee compensation, depreciation and intangible asset amortization. The disclosure requirements must be applied retrospectively to all prior periods presented in the financial statements. The effective date for the standard is for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the effects adoption of this guidance will have on the consolidated financial statements.
Recently adopted accounting pronouncements
ASU 2023-09, Improvements to Income Tax Disclosures
In December 2023 , the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 aims to enhance the transparency and decision usefulness of income tax disclosures. ASU 2023-09 modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state, and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024 . The Company adopted ASU 2023-09 prospectively in the first quarter of 2025. The adoption of ASU 2023-09 did not have a material impact on the Company’s financial position or results of operations.

Revolving Credit Facility and Senior Secured Debt - On September 25, 2025, the Company entered into a new credit agreement (the “JPM Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent, and a syndicate of lenders. The JPM Credit Agreement provides for a $ 23.0 million secured term loan (the “Term Loan”) with term payments through September 25, 2029, and a $ 5.0 million secured revolving credit facility (the “Revolver”) maturing September 25, 2027. Loans under the JPM Credit Agreement accrue interest at a rate per annum equal to, at the Company’s option, either a term rate based on the secured overnight financing rate (“SOFR”) plus a margin of 3.50 %, or the CB Floating Rate (“CBFR”) plus a margin of 2.50 %. Interest is payable in arrears, either at the end of the applicable interest period for SOFR-based loans or quarterly for CBFR-based loans.
Debt issuance costs incurred in connection with obtaining new debt facilities are capitalized and amortized over the term of the related debt. For the term loan, these costs are presented as a direct reduction of the carrying amount of the debt. For the revolving credit facility, such costs are presented as an asset. Amortization of debt issuance costs is included in interest expense in the condensed consolidated statements of comprehensive income (loss).
Principal payments on the term loan will commence on December 31, 2025, and will be made in quarterly installments of $ 1,437,500 on the last day of each fiscal quarter. The Company may prepay outstanding loans at any time without premium or penalty, subject to customary breakage costs for SOFR-based borrowings.

Retirement of Senior Secured Debt - Concurrently, on September 25, 2025, in connection with the funding of the term loan and the initial draw of $ 0.7 million under the revolver, the Company paid all amounts due under and terminated in full all commitments under the Note and Warrant Purchase and Security Agreement, dated August 6, 2020, with NH Expansion
14
Credit Fund Holdings LP and the related senior secured debt (collectively, the “Existing Debt”). The payoff and termination of the Existing Debt resulted in the release of all associated liens and security interests.

The full repayment of the Existing Debt was accounted for as a debt extinguishment under ASC 470-50. The Company recognized a $ 0.5 million loss on extinguishment of debt, which includes the write-off of unamortized debt issuance costs and debt discounts.

Debt Covenants and Restrictions - The JPM Credit Agreement contains customary covenants, including requirements to maintain certain financial ratios and restrictions on additional indebtedness, asset sales, and dividend payments.

As of September 30, 2025 , the Company was in compliance with all covenants under the JPM Credit Agreement.

Collateral and Security - The Company’s obligations under the JPM Credit Agreement are secured by a first-priority lien on substantially all of the Company’s tangible and intangible assets, including the Company’s equity interests in subsidiaries.

10. Promissory Notes Payable
Convertible Notes Payable and Convertible Notes Payable, Related Parties - In August 2022 , November 2022 , May 2023, December 2023, January 2024, and June 2024, the Company entered into Securities Purchase Agreements (the “Purchase Agreements”) for the sale in a private placement of (i) Future Advance Convertible Promissory Notes (the “Notes”) in an aggregate principal amount of $ 16.2 million in August 2022 , $ 4.0 million in November 2022 , $ 1.2 million in May 2023 , $ 1.9 million in December 2023, $ 4.6 million in January 2024 related to the conversion of the Asset-Backed Secured Promissory Notes, and $ 1.3 million in June 2024 (ii) Common Stock Purchase Warrants to purchase an additional 1.9 million shares of common stock with an exercise price of $ 25.13 per share and (iii) Common Stock Purchase Warrants to purchase an additional 1.9 million shares of common stock with an exercise price of $ 15.00 per share. Interest expense for the three and nine months ended September 30, 2025 totaled $ 0 , and interest expense for the three and nine months ended September 30, 2024 , totaled $ 1.5 and $ 4.3 million, res pectively.
Pursuant to the Notes, the Company promised to pay in cash and/or in shares of common stock, at a conversion price of $ 15.00 (the “Conversion Price”), the principal amount and interest at a rate of 15 % per annum on any outstanding principal. The Conversion Price of the Notes was subject to adjustment, including if the Company issued or sold shares of common stock for a price per share less than the Conversion Price of the Notes or if the Company listed its shares of common stock on The Nasdaq Capital Market and the average volume weighted average price of such common stock for the five trading days preceding such listing was less than $ 15.00 per share; provided, however, that the Conversion Price was never less than $ 3.75 . The Notes contained customary events of default and covenants, including limitations on incurrences of indebtedness and liens. The Notes had a term of 12 months from the date of issue.
In May 2024, the Company utilized its election to convert the May Notes into shares of common stock upon the Notes' maturity. The May Notes totaling $ 1.2 million in principal and $ 0.2 million interest were converted to 94,130 shares of common stock.
All remaining outstanding convertible notes payable and convertible notes payable related party converted on October 18, 2024 to 591,802 shares of common stock. The outstanding principal and interest converted totaled $ 8.9 million. The Company recognized a $ 0.3 million gain on conversion of the Notes.
Promissory note payable, related parties - In June 2024 the Company entered into a $ 0.5 million promissory note with a related party. Interest was accrued at 12 % with an original maturity date of December 3, 2024. The Note was paid in full with accrued interest in October 2024.
Acquisition Convertible promissory notes payable - In August 2020 , the Company entered into an asset purchase agreement with Celularity to acquire Celularity’s UltraMIST assets. A portion of the aggregate consideration of $ 24 million paid for the assets included the issuance of a promissory note to Celularity in the principal amount of $ 4 million (the “Seller Note”). The Seller Note matured on August 6, 2021, and was not repaid. The Company’s failure to pay the outstanding principal balance when due constituted an event of default under the terms of the Seller Note and, accordingly,
17
it began accruing additional interest of 5.0 % in addition to the 12.0 % initial rate, as of the date of the default. As of December 31, 2024 , the Seller Note had outstanding accrued interest of $ 0 . This Seller Note was settled in 2024 for a cash payment of $ 2.2 million.
Convertible promissory notes payable, related party - In August 2020 , the Company issued a convertible promissory note payable in the amount of $ 1.4 million. The note matured on August 6, 2021, and was not repaid and thus was in default. As of December 31, 2024 , the note had outstanding accrued interest of $ 0 .
The convertible promissory note was settled in 2024 for a cash payment of $ 1.4 million, which resulted in a gain on the extinguishment of debt of $ 0.8 million and a reduction in accrued interest of $ 0.8 million.

12. Stock-Based Compensation
On August 7, 2024, the stockholders of the Company approved the 2024 Equity Incentive Plan (the “2024 Plan”). The 2024 Plan authorizes the issuance of up to 1,376,556 shares of common stock. On August 19, 2025, at our annual meeting of stockholders, an amendment to the 2024 Plan was ratified, authorizing an additional 500,000 shares of common stock authorized for issuance under the plan. Stock options granted under the 2024 Plan include service-based, performance-based, and market-based awards. Service-based stock options generally vest over a three-year period, expire 10 years from the date of grant, and are forfeited upon separation from the Company. Performance-based stock options vest upon the achievement of pre-established financial or operational performance criteria, as determined by the Company’s Board of Directors or Compensation Committee. These awards generally expire five years from the date of grant and are subject to forfeiture if the performance goals are not achieved within the specified performance period. Market-based stock options vest upon the attainment of certain market conditions, such as specified stock price targets, and also expire five years after the grant date. The fair value of market-based awards is estimated using a Monte Carlo simulation model.
All awards under the 2024 Plan are subject to the terms and conditions of the 2024 Plan and the individual award agreements.
During the nine months ended September 30, 2025, the Company granted performance- and market-based option awards to three employees which provide for the vesting of up to 65,500 shares of common stock. Vesting is contingent upon the achievement of specified performance or market conditions, with 100 % of the related shares vesting upon satisfaction of each applicable condition.
18
The performance conditions include the achievement of (a) specific revenue recognized ( 12,750 shares), (b) specific adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) targets ( 12,750 shares), (c) listing on NASDAQ ( 10,000 shares), (d) the refinancing or repayment of certain debt obligations ( 10,000 shares), and (e) various operations related milestones ( 10,000 shares). The market condition relates to the attainment of a defined stock price target ( 10,000 shares).
During the nine months ended September 30, 2025, 5,500 shares subject to performance conditions ( 2,750 shares under criterion (a) and 2,750 shares under criterion (b)) were forfeited due to the termination of one of the employees. As a result, the maximum number of shares eligible to vest under these awards was reduced to 60,000 shares as of September 30, 2025.
As of September 30, 2025, the Company concluded that the performance conditions related to revenue, adjusted EBITDA, and half of the various operations related milestones were not probable of achievement, and accordingly, no compensation expense was recognized for those awards. The debt refinancing condition and half of the various operations related milestones were achieved during the quarter ended September 30, 2025, and the related compensation expense was recognized in the quarter. The NASDAQ listing condition was achieved during the quarter ended March 31, 2025, and the related compensation expense was recognized in the quarter ended September 30, 2025.
The market condition has not been met as of September 30, 2025, however, compensation expense for the market-based award is recognized on a straight-line basis over the requisite service period, regardless of whether the market condition is ultimately satisfied. If the condition is achieved prior to the end of the service period, any unrecognized expense will be recognized immediately.
On November 1, 2010, the Company approved the Amended and Restated 2006 Stock Incentive Plan of SANUWAVE Health, Inc. effective as of January 1, 2010 (the “Stock Incentive Plan”). Upon the approval of the 2024 Plan by the Company's stockholders, no further awards will be made under the Stock Incentive Plan.
The Stock Incentive Plan permitted grants of awards to selected employees, directors, and advisors of the Company in the form of restricted stock or options to purchase shares of common stock. Options granted may include non-statutory options as well as qualified incentive stock options. The Stock Incentive Plan is administered by the board of directors of the Company. The Stock Incentive Plan gives broad powers to the board of directors of the Company to administer and interpret the form and conditions of each option.
The following table presents stock compensation expense recognized by the Company for the three and nine months ended September 30, 2025 . Total unrecognized compensation cost related to equity awards as of September 30, 2025 was $ 10.1 million and is expected to be recognized over a weighted average period of 2.36 years. All stock compensation expense from the Stock Incentive Plan was recognized prior to 2024. The first grants from the 2024 Plan were issued in the three months ended December 31, 2024 , thus there is no expense for the three and nine months ended September 30, 2024 . The Company recognizes compensation expense on a straight-line basis over the requisite service period, net of actual forfeitures.

Valuation Information for Stock-Based Compensation

The fair value of each stock option award during the three and nine months ended September 30, 2025 was based on the closing price of the Company's common stock on the date of the grant. Expected volatility was based on 100% of the historical realized volatilities of peer companies. The risk-free interest rate was based on the implied yield for U.S. Treasury zero-coupon issue with the remaining term equal to the expected term. The expected holding period was calculated using the simplified method. No dividend was assumed as the Company does not pay regular dividends on its common stock and does not anticipate paying any dividends in the foreseeable future. The Company's policy is to recognize forfeitures as they occur.

The weighted average assumptions used in the Black-Scholes option pricing model in valuing stock options granted in the three and nine months ended September 30, 2025 are summarized in the table below:
Three Months Ended September 30, Nine Months Ended September 30,
2025 2025
Fair value at grant date $ 37.34 $ 30.61
Expected volatility 63 % 62 %
Risk-free interest rate 4 % 4 %
Expected holding period, in years 5.48 5.13
Dividend yield 0 % 0 %
13. Net Income (Loss) per Share
Basic net income (loss) per share is computed based on the weighted average number of shares outstanding during the applicable period, including nominally priced warrants. Diluted net income (loss) per share is computed by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock and dilutive common stock equivalents outstanding. Diluted net income (loss) per share is calculated based on the weighted average of shares of common stock outstanding and the number of additional shares that would have been outstanding if the potentially dilutive securities had been issued. The Company uses the treasury stock method to calculate the number of shares for the nominally priced warrants.

In September 2024, the Company did not have any dilutive common stock equivalents that were nominally priced. The following securities were excluded from the calculation of diluted net income per share during the nine months ended September 30, 2025 because the result would have been anti-dilutive.

15. License and Option Agreement
In March 2024, the Company entered into an exclusive license and option agreement (the "Patent License") with a third party licensee in connection with a portfolio of patents related to the field of intravascular shockwave applications. The Company received a one-time payment of $ 2.5 million related to this Patent License, which was recorded in other income during the three months ended March 31, 2024. The Company granted the Licensee an exclusive license to the patents and an option to acquire the patents for a period of 3 years following the effective date of the Agreement. Upon acquisition of the patents, the Licensee will distribute any resulting proceeds to the Company, including but not limited to any royalties, license fees, settlement payments, or other proceeds generated from the licensing or assertion of the patents, in accordance with a revenue sharing agreement.
On July 23, 2025, the Licensee exercised the acquisition option. In connection with such exercise, the Licensee and the Company executed a patent purchase agreement, and the Licensee made a $ 5.0 million cash payment to Sanuwave, Inc. on August 21, 2025. At the time of the Patent License and through the Licensees exercise of the acquisition option, the Company did not have any amounts capitalized related to the underlying portfolio of patents, nor was any write-down of assets recorded upon executing the Patent License or acquisition option. Accordingly, the Company recognized a $ 5.0 million gain on sale of patents within Other Income (Expense) on the condensed consolidated statements of comprehensive income (loss) for the three and nine months ended September 30, 2025. The Company does not have any ongoing obligations associated with the patent license. Additional proceeds may be provided to the Company under certain conditions of the agreement with the Licensee.
Contingent Consideration - The Company considers such royalties, license fees, settlement payments, or other proceeds as variable or contingent consideration. The Company determined that the amount of variable consideration would be constrained until the period the uncertainty related to the consideration is relieved.
16. Commitments and Contingencies
Litigation
In the ordinary course of business, the Company from time to time becomes involved in various legal proceedings involving a variety of matters. The Company does not believe there are any pending legal proceedings that will have a material adverse effect on the Company’s business, consolidated financial position, results of operations, or cash flows. However, the outcome of such legal matters is inherently unpredictable and subject to significant uncertainties. The Company expenses legal fees in the period in which they are incurred.
17. Segment Information
The Company operates in one reportable segment engaged in the design and sale of medical devices.
The accounting policies of the reportable segment are the same as those described in the summary of significant accounting policies. The Chief Operating Decision Maker ( “ CODM ” ) assesses performance for the reportable segment and decides how to allocate resources primarily based on gross margin that is also reported on the condensed consolidated statements of comprehensive income (loss). The measure of segment assets is reported on the condensed consolidated balance sheets as total assets.
The CODM uses gross profit to evaluate income (loss) generated from segment assets (return on assets) in deciding whether to reinvest profits or to apply them to other parts of the entity.
22
Net income (loss) is used to monitor budget versus actual results. The CODM also uses net income (loss) in competitive analysis by benchmarking to competitors. The competitive analysis along with the monitoring of budgeted versus actual results are used in assessing performance of the segment and in establishing management’s compensation.
Management has determined that Morgan Frank, CEO, is the CODM.
The following table sets forth our condensed consolidated statements of comprehensive income (loss) used by the CODM:

Item 2.   MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and the related notes appearing elsewhere in this report, and together with our audited consolidated financial statements, related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” as of and for the year ended December 31, 2024 included in our Annual Report on Form 10-K, filed with the SEC on March 20, 2025 (the “2024 Annual Report”).
Executive Summary
We continued to realize significant revenue growth during the three months ended September 30, 2025, as compared to the same period in 2024 . Revenue for the three months ended September 30, 2025, totaled $11.5 million , an increase of 22% , as compared to $9.4 million for the same period of 2024 . Revenue for the nine months ended September 30, 2025, totaled $31.0 million , an increase of 39% , as compared to $22.3 million for the same period of 2024 .
Net income for the three months ended September 30, 2025, was $10.3 million compared to net loss of $20.7 million for the same period in 2024 . The increase in our net income for the three months ended September 30, 2025, was primarily related to the change in fair value of derivative liabilities of $6.1 million for the three months ended September 30, 2025 compared to a loss of $18.8 million for the three months ended September 30, 2024 and $5.2 million in other income for the three months ended September 30, 2025 compared to none for the three months ended September 30, 2024 . The change in fair value of derivative liability relates to the valuation of warrants previously issued by the Company. Other income for the three months ended September 30, 2025 mainly consists of the one-time payment of $5.0 million related to the patent purchase agreement as described in Note 15 of our condensed consolidated financial statements for the period. For the three months ended September 30, 2025, our operating income totaled $1.5 million compared to $2.0 million for the same period of 2024. The decrease in net income was mainly due to an increase in non-cash charges for stock-based compensation of $1.4 million for the three months ended September 30, 2025 as compared to the same period of 2024.
Net income for the nine months ended September 30, 2025, was $5.7 million compared to a net loss of $18.6 million for the same period in 2024 . The increase in net income for the nine months ended September 30, 2025, was primarily related to the change in fair value of derivative liabilities of $2.2 million for the nine months ended September 30, 2025 compared to a loss of $17.6 million for the nine months ended September 30, 2024 and a decrease in interest expense in the nine months ended September 30, 2025 of $4.5 million compared to the same period of 2024. For the nine months ended September 30, 2025, our operating income totaled $4.3 million , which is an improvement of $1.4 million compared to the same period of 2024 . The increase in operating income was mainly driven by an increase in revenue and gross margin for the nine months ended September 30, 2025.


Non-GAAP Financial Measures
Throughout this Management’s Discussion and Analysis of Financial Condition and Results of Operations, we present certain financial measures that facilitate management's review of the operational performance of the Company and as a basis for strategic planning; however, such financial measures are not presented in our financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S.”) (“U.S. GAAP”). These financial measures are considered "non-GAAP financial measures" and are intended to supplement, and should not be considered as superior to, or a replacement for, financial measures presented in accordance with U.S. GAAP.
The Company uses Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) and Adjusted EBITDA to assess its operating performance. Adjusted EBITDA is Earnings before Interest, Taxes, Depreciation and Amortization adjusted for the change in fair value of derivatives and any significant non-cash or non-recurring infrequent charges. EBITDA and Adjusted EBITDA should not be considered as alternatives to net loss as a measure of financial performance or any other performance measure derived in accordance with U.S. GAAP, and they should not be construed as an inference that our future results will be unaffected by unusual or infrequent items. These non-GAAP financial measures are presented in a consistent manner for each period, unless otherwise disclosed. The Company uses these measures for the purpose of evaluating its historical and prospective financial performance, as well as its performance relative to competitors. These measures also help the Company to make operational and strategic decisions. The Company believes
24
that providing this information to investors, in addition to U.S. GAAP measures, allows them to see the Company’s results through the eyes of management, and to better understand its historical and future financial performance. These non-GAAP financial measures are also frequently used by analysts, investors, and other interested parties to evaluate companies in our industry, when considered alongside other U.S. GAAP measures.
EBITDA and Adjusted EBITDA have their limitations as analytical tools, and you should not consider them in isolation or as a substitute for analysis of our results as reported under U.S. GAAP. Some of these limitations are that EBITDA and Adjusted EBITDA:
• Do not reflect every expenditure, future requirements for capital expenditures or contractual commitments.
• Do not reflect all changes in our working capital needs.
• Do not reflect interest expense, or the amount necessary to service our outstanding debt.
As presented in the U.S. GAAP to Non-GAAP Reconciliations section below, our non-GAAP financial measure excludes the impact of certain charges that contribute to our net income (loss).

Total other income (expense) increased by $31.5 million to other income of $8.9 million for the t hree months ended September 30, 2025, as compared to an expense of $22.6 million for the same period of 2024 . The increase was primarily driven by the change in fair value of derivative liabilities of $24.9 million and other income of $5.2 million. The change in fair value of derivative liability relates to the valuation of warrants previously issued by the Company. Other income for the three months ended September 30, 2025 mainly consists of the one-time payment of $5.0 million related to the patent purchase agreement as described in Note 15 of our condensed consolidated financial statements for the period.
Total other income (expense) increased by $22.9 million to other income of $1.4 million for the nine months ended September 30, 2025, as compared to other expense of $21.5 million for the same period of 2024 . The increase was primarily driven by the change in fair value of derivative liabilities of $19.8 million, interest expense of $5.6 million, and other income of $2.5 million, partially offset by the gain on extinguishment of debt of $5.7 million. The change in fair value of derivative liability relates to the valuation of warrants previously issued by the Company. Other income for the nine months ended September 30, 2025 mainly consists of the one-time payment of $5.0 million related to the patent purchase agreement as described in Note 15 of our condensed consolidated financial statements for the period. Other income for the nine months ended September 30, 2024 mainly consists of the one-time payment of $2.5 million related to the Patent License agreement as described in Note 15 of our condensed consolidated financial statements for the period.
Liquidity and Capital Resources
From inception through the year ended December 31, 2023, we incurred losses from operations each year. As of September 30, 2025, we had an accumulated deficit of $245.7 million . Historically, our operations have primarily been funded from the sale of capital stock, issuances of notes payable, and convertible debt securities.
We have incurred recurring net losses in prior years, currently have a significant accumulated deficit, and have experienced negative working capital. Previously, the scheduled maturity of the Senior Secured Note (as defined in Note 7) in September 2025 raised substantial doubt about our ability to continue as a going concern for a period of 12 months from the filing of the prior Form 10-Q.
However, as described in Note 7 of our condensed consolidated financial statements for the period , we successfully refinanced our outstanding debt during the three months ended September 30, 2025. The refinancing extended the maturity of our debt and provided the option for additional liquidity to support ongoing operations through the s ecured revolving credit facility . In addition, the operating income achieved in the current year, the receipt of $5 million from the patent purchase agreement, and the capital raised from a private placement in October 2024 have all contributed to a significant improvement in our financial position.

As discussed in Note 2, management has evaluated our ability to continue as a going concern in light of these developments. Based on the successful refinancing and other recent initiatives, management believes the Company has
28
sufficient resources to meet its obligations as they become due and to continue as a going concern for at least the next 12 months. We continue to monitor our financial position, liquidity, and compliance with debt covenants on an ongoing basis.

Management remains focused on maintaining the Company’s improved financial position and operational momentum. While we continue to monitor our liquidity and capital resources closely, we believe that the successful refinancing of our debt, as described in Note 7, together with our recent operating income and capital initiatives, have significantly strengthened our ability to meet our obligations as they come due. As discussed in Note 2, these actions have alleviated the substantial doubt about our ability to continue as a going concern. We will continue to evaluate opportunities to further enhance our capital structure and support our growth strategy. Although we cannot predict all future events or guarantee that unforeseen circumstances will not arise, we are confident that the steps taken to date position the Company well to support ongoing operations and execute on our strategic objectives.

Critical Accounting Estimates
We have used various accounting policies to prepare the condensed consolidated financial statements in accordance with U.S. GAAP. Our significant accounting policies are disclosed in Note 3 to the consolidated financial statements in Part II Item 8. “Financial Statements and Supplementary Data” in our 2024 Annual Report on Form 10-K filed with the SEC on March 20, 2025.
The preparation of the condensed consolidated financial statements, in conformity with U.S. GAAP, requires us to use judgment in making estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. These estimates reflect our best judgment about economic and market conditions and the potential effects on the
29
valuation and/or carrying value of assets and liabilities based upon relevant information available. We base our estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.
Segment and Geographic Information
We have determined that we have one operating segment. Our revenues are generated from sales primarily in the United States. All significant expenses are generated in the United States and all significant assets are in the United States. For further information on the Company's operating segment, refer to Note 17 to the condensed consolidated financial statements.
Effects of Inflation
Our assets are, to an extent, liquid in nature, so they are not significantly affected by inflation. However, the rate of inflation, which remains elevated, affects expenses such as employee compensation, office space leasing costs and research and development charges, which may not be readily recoverable. To the extent inflation results in rising interest rates and has other adverse effects on the market, it may adversely affect our consolidated financial condition and results of operations.
Item 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
As a “smaller reporting company” as defined by Item 10 of Regulation S-K, we are not required to provide the information required under this item.
Item 4.   CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are designed to provide reasonable assurance 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. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
We carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer and accounting officer), of the effectiveness of the design and operation of our disclosure controls and procedures as of September 30, 2025. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not operating effectively as of September 30, 2025.
As of December 31, 2024, the Company identified the following material weaknesses which continue to exist as of September 30, 2025:

The Company lacked internal controls over key accounting and IT processes, including Equity, Financial Reporting, Accounts Payable, Expenses, Revenue, Accounts Receivable, Tax, Cash, Debt, Fixed Assets, Inventory, Commissions, Entity-Level Controls, Human Resources/Payroll, and IT General Controls (change management, operations, and access security). The Company lacked expertise and resources to analyze and properly apply U.S. GAAP to complex and non-routine transactions such as complex financial instruments and derivatives and complex sales distributing agreements with select vendors. The Company lacked internal resources to analyze and properly apply U.S. GAAP to account for financial instruments included in service agreements with select vendors.

As a result, management concluded that its internal control over financial reporting was not effective as of September 30, 2025.

30
Remediation Plan

Management is fully committed to addressing the material weaknesses in our internal controls and has implemented several key initiatives to strengthen them. To that end, the Company has continued to implement and enhance appropriate internal controls and contracted with CliftonLarsonAllen LLP starting in the third quarter 2023 to conduct a valuation engagement. This engagement aims to provide an estimated conclusion of value and a summary, restricted appraisal report to assist management in determining the fair value of warrants to purchase the Company’s stock, embedded derivatives, and other interests.

We plan to remediate and implement these controls for high-risk processes throughout 2025. We hired a highly experienced Director of Internal Audit to review, adjust, as needed, and test our internal controls and ensure they function as intended. We recently deployed Governance, Risk, and Compliance software from Workiva to support these efforts. Furthermore, we plan to hire additional personnel and segregate certain duties to enhance our control activities and effectively mitigate risks. Until we fully remediate the material weaknesses, we will perform additional analyses and procedures to ensure our consolidated financial statements comply with U.S. GAAP. We remain vigilant in identifying any additional material weaknesses that may arise and are prepared to adjust our remediation strategies as needed.

We are collaborating with an external vendor to enhance our IT general controls over our enterprise resource planning system. This initiative aims to establish a robust framework for executing IT general controls, addressing weaknesses in our internal controls, and providing a solid framework for future testing.

The existence of any material weakness or significant deficiency requires management to devote significant time and incur significant expense to remediate any such material weaknesses or significant deficiencies, and management may not be able to remediate any such material weaknesses or significant deficiencies in a timely manner. The existence of any material weakness in our internal control over financial reporting could also result in errors in our financial statements that could require us to restate our financial statements, cause us to fail to meet our reporting obligations, and cause shareholders to lose confidence in our reported financial information, all of which could materially and adversely affect our business and stock price.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2025, that materially affect, or are reasonably likely to materially affect, our internal control over financial reporting, except as disclosed in “Remediation Plan” above.
PART II — OTHER INFORMATION
Item 1.          LEGAL PROCEEDINGS
For information regarding legal proceedings at September 30, 2025, see Note 16 to the condensed consolidated financial statements, which information is incorporated herein by reference.
Item 1A.       RISK FACTORS

Except as set forth below, there have been no material changes from our risk factors as previously reported in Part I, Item 1A “Risk Factors” in our 2024 Annual Report.
Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.
We have incurred net losses since our inception. If not utilized, some of our federal and state net operating losses (“NOLs”) carryforwards will begin to expire in various years beginning after 2033. Under the Internal Revenue Code of 1986, as amended, (the “Code”), and certain similar state tax provisions, we are generally allowed to carry forward our NOLs from a prior taxable year to offset our future taxable income, if any, until such NOLs are used or expire, subject to certain limitations. The same is true of other unused tax attributes, such as tax credits. In addition, under Section 382 of the Code, a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change NOLs to offset future taxable income. During the quarter ended June 30, 2025, we completed an IRC Section 382 analysis of our tax attributes. That analysis showed that $44.2 million of our NOL tax attributes would expire before becoming available under our limitation as a result of shifts in our ownership. We have adjusted our tax attributes to account for this limitation.

Item 2.          UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
None.
Item 3.          DEFAULTS UPON SENIOR SECURITIES
Not applicable.

Item 5.          OTHER INFORMATION
During the three months ended September 30, 2025, none of our directors or officers (as defined in Rule 16a-1(f) of the Exchange Act) adopted or terminated any contract, instruction or written plan for the purchase or sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) of the Exchange Act or any non-Rule 10b5-1 trading arrangement (as defined in the SEC’s rules).
