SANUWAVE Health, Inc. (OTC: SNWV) posts Q2 loss and details control issues
SANUWAVE Health, Inc. reported Q2 2026 revenue of $9.7 million, down 3% from Q2 2025, and a net loss of $0.7 million versus prior-year net income of $0.6 million. For the first six months of 2026, revenue was $19.4 million, essentially flat year over year, while the net loss narrowed to $2.1 million from $5.6 million.
Gross margin remained high at 76% in Q2 2026 but declined modestly due to lower UltraMIST system volumes and pricing and a mix shift toward consumables. Operating expenses increased across general and administrative, selling and marketing, and research and development, driving an operating loss of $0.3 million for the quarter and $1.4 million year-to-date. Below operating income, total other expense improved sharply, helped by a large reduction in interest expense after a 2025 debt refinancing.
Cash and cash equivalents were $9.4 million at June 30, 2026, with $18.7 million outstanding on a secured term loan and $0.7 million drawn on a revolving credit facility; operating activities generated $0.8 million of cash in the first half. The company has accrued $4.5 million for state and local sales taxes, interest, and penalties and is resolving these exposures through voluntary disclosure agreements. Disclosure controls and internal control over financial reporting remained ineffective due to previously identified material weaknesses in accounting resources, revenue recognition and sales tax processes, and information technology controls, with remediation efforts ongoing.
Positive
- Net loss and interest expense materially improved: Six-month net loss declined to $2.1 million from $5.6 million, and interest expense fell to $1.1 million from $3.8 million, reflecting the September 2025 refinancing.
Negative
- Ongoing material weaknesses in internal controls: Management concluded disclosure controls and internal control over financial reporting were not effective as of June 30, 2026, citing insufficient accounting resources, revenue and sales tax control deficiencies, and IT control weaknesses.
- Significant accrued sales and use tax obligations: The company has recorded $4.5 million of state and local sales tax, interest, and penalties related mainly to voluntary disclosure agreements, which remain subject to final settlement with taxing authorities.

6 terms
Adjusted EBITDA financial
"The Company uses Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) and Adjusted EBITDA"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
right-of-use asset financial
"the Company recognizes a right-of-use (“ROU”) asset and a lease liability for all leases"
A right-of-use asset is the value a company records on its balance sheet for the practical use of something it leases — like the benefit of living in a rented office or using leased equipment for a set period. Investors care because it turns many leases into on-balance-sheet assets and matching liabilities, which can change reported leverage, asset base and performance metrics much like taking on a loan would.
material weaknesses financial
"management has identified material weaknesses in the Company’s internal control over financial reporting"
Material weaknesses are significant flaws in a company’s systems for ensuring its financial reports are accurate and reliable. Like a broken lock on a safe, they increase the chance that financial statements contain big errors or omissions, which can mislead investors about performance and risk; discovering one often raises questions about management oversight, may lead to restated results, and can affect investor confidence and a company’s valuation.
valuation allowance financial
"the Company maintained a valuation allowance on the overall net deferred tax asset"
A valuation allowance is a reserve set aside to reduce the value of certain assets on a company's financial records when there is uncertainty about whether they will generate the expected benefits. It acts like a caution sign, indicating that some assets might not be fully recoverable or worth their recorded amount. This matters to investors because it provides a more realistic picture of a company's financial health and potential risks.
voluntary disclosure agreements financial
"the Company has entered into voluntary disclosure agreements (VDAs) with numerous jurisdictions"
incremental borrowing rate financial
"discounted at the Company's incremental borrowing rate of 7.2%"

SANUWAVE HEALTH, INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
June 30, 2026
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. Sanuwave was founded in 2004 and is headquartered in Eden Prairie, Minnesota.
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. All significant intercompany accounts and transactions have been eliminated. Amounts reported within this Quarterly Report on Form 10-Q are presented in thousands, and therefore, the sum of the components may not equal the total amount reported due to rounding.
The financial information as of June 30, 2026, and for the three and six months ended June 30, 2026, and 2025 is unaudited; however, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement have been included. Operating results for the three and six months ended June 30, 2026, are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2026.
The condensed consolidated balance sheet on December 31, 2025, 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, 2025, as filed with the SEC on March 26, 2026 (the “2025 Annual Report”).
Reclassification - Certain accounts in the prior period condensed consolidated statement of cash flows have been reclassified to conform to the presentation of the current period consolidated financial statements. These reclassifications had no effect on the previously reported operating results.
2. Restatement of Previously Issued Financial Statements
In connection with the preparation of the Company’s consolidated financial statements for the year ended December 31, 2025, the Company engaged a specialist to conduct a sales and use tax nexus study. Management concluded that the Company had a historical state sales and use tax liability related to prior periods. The Company is required and subject to collect and remit sales and use tax in state and local jurisdictions where it has economic and physical nexus. During the year ended December 31, 2025, the Company determined that a sales tax liability existed and estimated a liability for sales transactions processed in jurisdictions where it had not previously reported.
The liability includes an estimate for each state, to account for any penalties and interest that is due on the base tax amount owed. The error resulted in an understatement of accrued expenses for state and local sales tax, including related interest and penalties, in the condensed consolidated financial statements as of and for the three and six months ended June 30, 2025. As a result of correcting this liability, general and administrative expenses and interest expense were increased in the affected periods, resulting in a one-time, non-recurring increase in reported expenses for the three and six months ended June 30, 2025. As part of its remediation of the underlying sales tax obligations, the Company has entered into voluntary disclosure agreements (VDAs) with numerous jurisdictions and has begun remitting payments required thereunder. The Company is currently awaiting responses from the remaining jurisdictions and expects to finalize the remediation process upon receipt thereof.
In addition to the errors related to sales tax liabilities, the Company identified that revenue was overstated and current portion of contract liabilities and contract liabilities, less current portion were understated related to extended warranties for the three and six months ended June 30, 2025. The errors related to the Company's accounting for extended warranty contracts sold at a discount in conjunction with its products. When extended warranties were sold at a discounted price, the
10
Table of Contents
Company did not allocate the discount proportionally across all performance obligations in the contract in accordance with Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers.
Specifically, ASC 606 requires that a discount present in a contract be allocated proportionally across all performance obligations based on their relative standalone selling prices, unless specific criteria are met to allocate the discount entirely to one or more performance obligations. The Company incorrectly absorbed the entire discount within the extended warranty performance obligation rather than allocating a proportionate share of the discount to the other performance obligations in the contract. This caused the transaction price allocated to the extended warranty to be understated and the transaction price allocated to the other performance obligations to be overstated, resulting in revenue being recognized on the other performance obligations in excess of the amounts that should have been allocated to them. Consequently, revenue was overstated and contract liabilities associated with the extended warranty was understated for the three and six months ended June 30, 2025.
The restatement was previously disclosed in the 2025 Annual Report.

Income Tax Effects
The Company maintains a full valuation allowance against its net deferred tax assets. Accordingly, the restatement adjustments resulted in no net income tax benefit or expense for any period presented, and the effective tax rate is unchanged.
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 the 2025 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.
Software Development Costs
The Company accounts for internal-use software costs in accordance with ASC Topic 350-40, Intangibles—Goodwill and Other—Internal-Use Software, as amended by ASU No. 2025-06, which the Company early adopted prospectively effective January 1, 2026.
The Company capitalizes costs associated with software developed or obtained for internal use, including software licensed from third-party developers, when management has authorized and committed to funding the project and it is probable that the project will be completed and the software will be used for its intended purpose. Costs that do not meet these criteria, including training costs, general and administrative costs, and post-implementation maintenance costs, are expensed as incurred.
Capitalized internal-use software costs are recorded as intangible assets at cost and amortized on a straight-line basis over the estimated useful life of the software, which the Company has estimated to be three to five years , beginning when the software is substantially complete and ready for its intended use. The Company reviews capitalized software for impairment in accordance with its policy for long-lived assets.
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 condensed consolidated balance sheets; lease expense for these leases 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.
12
Table of Contents
Leases are classified as either operating or finance leases at the commencement date. The Company did not have any finance leases as of June 30, 2026, or December 31, 2025. Operating lease ROU assets and liabilities are presented separately on the condensed consolidated balance sheets.
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.
The Company’s lease agreements do not contain variable lease payments; all lease payments are fixed and included in the measurement of lease liabilities.
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 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 standard will have on the financial statement disclosures.
Recently adopted accounting pronouncements
ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software
In September 2025, the FASB issued ASU No. 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This ASU increases the operability of the recognition guidance by removing all references to "project stages" and clarifying when an entity is required to start capitalizing software costs. The Company early adopted this ASU prospectively beginning in fiscal year 2026.
ASU 2023-09, Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU primarily requires disaggregated annual information about a company's effective tax rate reconciliation and income taxes paid. The Company adopted this ASU prospectively beginning with 2025. Prior period disclosures have not been restated to conform to the current year period presentation.

6. Property and Equipment
Depreciation expense related to property and equipment for the three months ended June 30, 2026 and 2025 was $137 thousand and $72 thousand, respectively. Depreciation expense related to property and equipment for the six months ended June 30, 2026 and 2025 was $255 thousand and $141 thousand, respectively.
7. Leases
Operating lease commitments - On March 27, 2025, the Company entered into a new operating lease agreement for its new headquarters in Eden Prairie, Minnesota. The lease term commenced on March 28, 2025.
Lease Modification - Effective March 24, 2026, the Company modified its lease agreement for its headquarters. The lease amendment expands the existing property and extends for a period of 5.1 years, expiring on April 30, 2031. The lease includes an option to renew for an additional 5 years at the Company's discretion. As a result of the modification, the Company remeasured the related right-of-use asset and lease liability.
The modification resulted in an increase of $0.6 1.0 million. The modified measurement of the lease liability was $1.6 million, which represents the present value of the lease payments over the lease term, discounted at the Company's incremental borrowing rate of 7.2 %.
Lease-incentive - As part of the new office lease amendment, the Company is entitled to receive a reimbursement payment from the lessor as a lease incentive. This payment, totaling $0.3 million, is intended to offset certain costs associated with leasehold improvements and is estimated to be paid in June 2027. Under ASC 842, lease incentives are accounted for as a reduction of the right-of-use asset and recognized over the lease term.
Lease payments - Under the terms of the modified lease, the Company is obligated to make increased monthly lease payments starting May 1, 2026, with an annual escalation of 3.5 % starting on May 1, 2027. The total minimum lease payments over the modified lease term amount to approximately $2.3 million.
Lease expense - For the three and six months ended June 30, 2026, the Company recognized lease expense of $64 thousand and $110 thousand, respectively, related to this operating lease. For the three and six months ended June 30, 2025, the Company recognized lease expense of $37 thousand and $49 thousand, respectively, related to this operating
14

lease. These expenses are included in general and administrative expenses in the condensed consolidated statements of comprehensive (loss) income.
As of June 30, 2026, the maturities of the Company’s operating leases, which have initial or remaining lease terms more than one year, consist of the following:

8. Long Term Debt, Revolving Credit Facility and Senior Secured Debt
The following table summarizes outstanding debt at June 30, 2026 and December 31, 2025:
| June 30, 2026 | December 31, 2025 | ||||||||||||||||||||||||||||||||||||||||
| (in thousands) | Principal | Debt Issuance Costs | Carrying Value | Principal | Debt Issuance Costs | Carrying Value | |||||||||||||||||||||||||||||||||||

Secured revolving credit facility | $ | $ | ( | $ | $ | $ | ( | $ | |||||||||||||||||||||||||||||||||
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 Revolver, such costs are presented as an asset. Amortization of debt issuance costs is included in interest expense in the condensed consolidated statements of comprehensive loss.
Principal payments on the Term Loan commenced on December 31, 2025, and will be made in quarterly installments of $1.4 million 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

Table of Contents
Expansion Credit Fund Holdings LP and the related senior secured debt (collectively, the “Prior Debt”). The payoff and termination of the Prior Debt resulted in the release of all associated liens and security interests.
The full repayment of the Prior Debt was accounted for as a debt extinguishment under ASC 470-50. On September 25, 2025, the Company recognized a $0.5 million loss on extinguishment of debt, which included 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 June 30, 2026, 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.
Maturity Analysis - Future principal payments on the Term Loan and Revolver are due as follows:

The state and local sales tax, penalty, and interest balances relate primarily to the Company’s VDAs with various state taxing authorities. The Company previously identified that it had not collected and remitted sales and use taxes in certain jurisdictions where it had established nexus. In prior periods, the Company recorded an estimated liability for the unpaid taxes, interest, and penalties. During the six months ended June 30, 2026, the Company initiated VDAs with certain taxing authorities to remediate the noncompliance.

The remaining VDA liability represents the Company’s best estimate of the pre-registration exposure and is subject to adjustment as VDA negotiations are completed with the respective state taxing authorities.
Upon settlement, the Company released the related accruals and recognized a net benefit in the condensed consolidated statements of comprehensive (loss) income, reflecting the excess of amounts previously accrued over the actual amounts owed. The Company recorded additional estimated obligations for sales occurring during the current period in jurisdictions where the Company has identified a filing obligation but has not yet completed the remediation process.

11. 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. In August 2025, at the annual meeting of stockholders, an amendment to the 2024 Plan was approved, authorizing an additional 500,000 shares of common stock for issuance under the 2024 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
18
Table of Contents
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 six months ended June 30, 2026, the Company granted performance-based awards to two employees which provide for the vesting of up to 8,500 shares of common stock. Vesting is contingent upon the achievement of specified performance conditions, with 100 % of the related shares vesting upon satisfaction of each applicable condition. The performance conditions include the achievement of (a) specific revenue recognized (6,000 shares) and (b) a specific operational milestone (2,500 shares).
During the fiscal year ended December 31, 2025, the Company granted performance-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. During 2025, certain awards were forfeited due to employee termination and missed milestone deadlines, certain performance and market conditions were achieved and the related compensation expense was recognized, and certain market-based awards expired unachieved. As a result, options exercisable for 20,000 shares remain outstanding and unvested as of June 30, 2026 relating to performance-based option award, all of which are subject to revenue and adjusted EBITDA performance conditions. Options exercisable for 10,000 shares remain outstanding and unvested as of June 30, 2026 relating to market conditions, which relates to the attainment of a defined stock price target.
As of June 30, 2026, the Company concluded that the performance conditions related to revenue, adjusted EBITDA, and operational milestones were not probable of achievement, and accordingly, no compensation expense was recognized for any performance-based awards.
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 six months ended June 30, 2026 and 2025. Total unrecognized compensation cost related to equity awards as of June 30, 2026 was $10.6 million and is expected to be recognized over a weighted average period of 2.01 years. 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 six months ended June 30, 2026 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 six months ended June 30, 2026 are summarized in the table below:

12. Net (Loss) Income per Share
Basic net (loss) income per share is computed based on the weighted average number of shares outstanding during the applicable period, including nominally priced warrants. Diluted net (loss) income per share is computed by dividing the net (loss) income attributable to common stockholders by the weighted average number of shares of common stock and dilutive common stock equivalents outstanding. Diluted net (loss) income 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.

Diluted net (loss) income per share is computed by dividing the net (loss) income attributable to common stockholders by the weighted average number of shares of common stock and dilutive common stock equivalents outstanding that are nominally priced. To the extent that securities are “anti-dilutive,” they are excluded from the calculation of diluted net loss per share. As a result of the net loss for the three and six months ended June 30, 2026, and six months ended June 30, 2025, all potentially dilutive shares in such periods were anti-dilutive and therefore excluded from the computation of diluted net loss per share. As a result of the net income for the three months ended June 30, 2025, all dilutive shares were included in the computation of diluted net income per share. Anti-dilutive equity securities consist of the following:

13. Concentration of Limited Suppliers
The Company currently purchases most of its product component materials from single suppliers and all of its finished product is assembled by a single supplier. The loss of any of these suppliers could result in a disruption in production. The percentages of purchases from major vendors of the Company that represented ten percent or more of total purchases were as follows:

14. 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 fiscal year ended December 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 Patent License. Upon acquisition

Table of Contents
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 licensee's 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 consolidated statements of comprehensive income (loss) for the fiscal year ended December 31, 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.
15. 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.
16. Segment Information
The Company operates in one
The accounting policies of the reportable segment are the same as those described in the summary of significant accounting policies. The Company's chief operating decision maker (“CODM”) assesses performance for the reportable segment and decides how to allocate resources primarily based on net (loss) income that is also reported on the condensed consolidated statements of comprehensive loss. The measure of segment assets is reported on the condensed consolidated balance sheets as total consolidated assets.
Net (loss) income is used to monitor budget versus actual results. The CODM also uses net (loss) income 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, Chief Executive Officer, is the CODM.

17. Income Taxes
At June 30, 2026, and December 31, 2025, the Company maintained a valuation allowance on the overall net deferred tax asset, as it was deemed more likely than not the net deferred tax asset will not be realized. At each reporting period, the Company evaluates the realizability of its deferred tax assets based on all available evidence. Any future release of the valuation allowance would result in a benefit to income tax expense for the period the release is recorded, which could have a material impact on net (loss) income.

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, 2025, included in our Annual Report on Form 10-K, filed with the SEC on March 26, 2026 (the “2025 Annual Report”).
Executive Summary
Revenue for the three months ended June 30, 2026 totaled $9.7 million, a decrease of approximately 3% compared to $10.1 million for the same period in 2025. Revenue for the six months ended June 30, 2026 totaled $19.4 million, approximately flat compared to $19.4 million for the same period in 2025.
Net loss for the three months ended June 30, 2026 was $0.7 million, compared to net income of $0.6 million for the same period in 2025. The change from net income to a net loss was primarily attributable to an operating loss of $0.3 million in the current-year period, compared to operating income of $1.4 million in the prior-year period, reflecting higher operating expenses during the current-year period, including increased headcount costs, stock-based compensation, and research and development that outpaced a modestly lower gross margin on reduced revenue. Total other expense, net improved to $0.4 million from $0.9 million, as significantly lower interest expense more than offset the non-recurrence of a $1.0 million gain from the change in fair value of derivative liabilities recognized in the prior-year period.
Net loss for the six months ended June 30, 2026 was $2.1 million, compared to a net loss of $5.6 million for the same period in 2025. The reduction in net loss was driven principally by items below operating income, including the non-recurrence of a $3.9 million loss from the change in fair value of derivative liabilities recognized in the prior-year period and a $2.8 million decrease in interest expense following our September 2025 debt refinancing. These improvements were partially offset by a decline in operating results: our operating loss for the six months ended June 30, 2026 was $1.4 million, compared to operating income of $2.0 million for the same period in 2025. The decline in operating results for the six months ended June 30, 2026 was primarily driven by higher operating expenses, including increased research and development, selling and marketing, and general and administrative spending, together with a slight decline in gross margin.
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 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.

Table of Contents
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 (loss) income.

Revenue
Revenues for the three months ended June 30, 2026 were $9.7 million, compared to $10.1 million for the same period of 2025, a decrease of $0.3 million, or 3%. The decrease was primarily driven by a decline in UltraMIST® system revenue, which decreased to $2.3 million from $3.4 million, or approximately 34%, partially offset by growth in consumables revenue, which increased to $7.3 million from $6.5 million, or approximately 12%. The decrease in UltraMIST® system revenue for the three months ended June 30, 2026 compared to the same period in 2025, was primarily driven by a 29% decline in unit volume, reflecting weaker capital sales due to financial pressures in the industry as well as increased availability of used UltraMIST® systems in the market. UltraMIST® system revenue was also impacted by a 9% decrease in average selling price, primarily due to a higher reseller mix. The increase in consumables revenue for the three months ended June 30, 2026 compared to the same period in 2025, was primarily driven by a 27% increase in unit volume, reflecting strong consumable utilization across our active installed base. This consumable growth was partially offset by a 11% decrease in average selling price due to a higher mix of reseller sales.
Revenues for the six months ended June 30, 2026 were $19.4 million, approximately flat compared to $19.4 million for the same period of 2025. Consumables revenue increased to $14.0 million from $12.5 million, or approximately 11%, substantially offset by a decline in UltraMIST® system revenue to $5.2 million from $6.6 million, or approximately 22%. The decrease in UltraMIST® system revenue for the six months ended June 30, 2026 compared to the same period in 2025, was primarily driven by a 16% decline in unit volume, reflecting weaker capital sales due to financial pressures in the industry as well as increased availability of used UltraMIST® systems in the market. UltraMIST® system revenue was also impacted by an 8% decrease in average selling price, primarily due to a higher reseller mix. The increase in consumables revenue for the six months ended June 30, 2026, compared to the same period in 2025, was primarily driven by a 24% increase in unit volume, reflecting strong consumable utilization across our active installed base. This consumable growth was partially offset by an 8% decrease in average selling price due to a higher mix of reseller sales.
Cost of Revenues
Cost of revenues for the three months ended June 30, 2026 was $2.3 million, compared to $2.2 million for the same period of 2025. Gross margin as a percentage of revenues was 76% for the three months ended June 30, 2026, compared to 78% for the same period in 2025. The decline in gross margin percentage was primarily driven by a shift in revenue mix toward consumables sales and away from higher-margin system sales, lower average sales prices due to a higher reseller mix, and

an increase in personnel costs within cost of revenues for the three months ended June 30, 2026, compared to the same period in 2025.
Cost of revenues for the six months ended June 30, 2026 was $4.5 million, compared to $4.2 million for the same period of 2025. Gross margin as a percentage of revenues was 77% for the six months ended June 30, 2026, compared to 79% for the same period in 2025. The decline in gross margin percentage was primarily driven by a shift in revenue mix toward consumables sales and away from higher-margin system sales and lower average sales prices due to a higher reseller mix, combined with increased personnel costs within cost of revenues.
General and Administrative
General and administrative expenses for the three months ended June 30, 2026 were $4.9 million, compared to $4.4 million for the same period of 2025, an increase of $0.5 million, or 12%. The increase was primarily due to higher personnel costs of $0.5 million (including stock-based compensation), higher legal and professional fees of $0.6 million, and increased bad debt expense of $0.2 million, partially offset by a $0.9 million reduction in state and local sales tax accruals.
General and administrative expenses for the six months ended June 30, 2026 were $10.2 million, compared to $9.2 million for the same period of 2025, an increase of $0.9 million, or 10%. The increase was primarily due to higher personnel costs of $1.0 million (including stock-based compensation), higher legal and professional fees of $0.7 million, increased bad debt expense of $0.2 million, and increased software costs of $0.2 million, partially offset by a $0.9 million reduction in state and local sales tax accruals and lower public company costs of $0.3 million from initial Nasdaq listing fees in the six months ended June 30, 2025 that did not recur.
Selling and Marketing
Selling and marketing expenses for the three months ended June 30, 2026 were $1.9 million, compared to $1.7 million for the same period of 2025, an increase of $0.2 million, or 15%. The increase was primarily due to higher consulting costs of $0.2 million and increased travel costs of $0.1 million.
Selling and marketing expenses for the six months ended June 30, 2026 were $4.3 million, compared to $3.2 million for the same period of 2025, an increase of $1.1 million, or 35%. The increase was primarily due to higher consulting costs of $0.6 million, increased personnel costs of $0.5 million (primarily higher salary expense and stock-based compensation), and increased travel costs of $0.2 million, partially offset by lower sales commissions of $0.3 million.
Research and Development
Research and development expenses for the three months ended June 30, 2026 were $0.6 million, compared to $0.2 million for the same period of 2025, an increase of $0.4 million. The increase was primarily due to higher personnel costs of $0.3 million, including increased stock-based compensation of $0.1 million, and higher consulting costs of $0.1 million.
Research and development expenses for the six months ended June 30, 2026 were $1.3 million, compared to $0.4 million for the same period of 2025, an increase of $0.9 million. The increase was primarily due to higher personnel costs of $0.4 million, including increased stock-based compensation of $0.2 million, higher consulting costs of $0.4 million, and increased development project and software costs of $0.1 million.

Total Other Expense, net was $0.4 million for the three months ended June 30, 2026, compared to $0.9 million for the same period of 2025, a decrease in net expense of $0.5 million. The decrease was primarily driven by a $1.4 million reduction in interest expense, partially offset by the non-recurrence of a $1.0 million gain from the change in fair value of derivative liabilities recognized in the prior-year period. The change in fair value of derivative liabilities relates to the valuation of warrants previously issued by the Company.
Total Other Expense, net was $0.7 million for the six months ended June 30, 2026, compared to $7.6 million for the same period of 2025, a decrease in net expense of $6.9 million. The decrease was primarily driven by the non-recurrence of a $3.9 million loss from the change in fair value of derivative liabilities recognized in the prior-year period, and a $2.8 million reduction in interest expense, reflecting the September 2025 refinancing of our senior secured debt. The change in fair value of derivative liabilities relates to the valuation of warrants previously issued by the Company.
Liquidity and Capital Resources
From inception through the year ended December 31, 2024, we incurred losses from operations each year, before achieving net income for the year ended December 31, 2025. As of June 30, 2026, we had an accumulated deficit of $244.8 million.
Historically, our operations have primarily been funded from the sale of capital stock, issuances of notes payable, and convertible debt securities. During the third quarter of 2025, we entered into the JPM Credit Agreement, which provided a $23.0 million Term Loan and a $5.0 million Revolver, the proceeds of which were used to repay and terminate the Prior Debt, as described in Note 8 to the condensed consolidated financial statements. The JPM Credit Agreement extended the maturity of our debt obligations and provided additional liquidity through the Revolver. Together with the positive cash flow from operations generated in 2025 and the $5.0 million received in connection with the patent purchase agreement described in Note 14 of the condensed consolidated financial statements, these actions strengthened our liquidity position and capital structure.
As of June 30, 2026, we had cash and cash equivalents of $9.4 million, $18.7 million outstanding under our Term Loan, and $0.7 million drawn under our Revolver. We were in compliance with all financial and other covenants under the JPM Credit Agreement as of June 30, 2026.
Based on our current cash position, anticipated cash flows from operations, and availability under our Revolver, we believe we will have sufficient resources to meet our working capital needs, capital expenditures, and debt service obligations for at least the next twelve months from the date of issuance of these condensed consolidated financial statements. We continue to monitor our financial position, liquidity, and compliance with debt covenants on an ongoing basis. We intend to continue to evaluate opportunities to further enhance our capital structure and support our growth strategy.

Cash Flows from Operating Activities
Cash provided by operating activities for the six months ended June 30, 2026 totaled $0.8 million. This primarily reflected non-cash charges, including $3.1 million of stock-based compensation expense, $0.6 million of depreciation and amortization, $0.4 million of provision for credit losses, and $0.1 million of amortization of debt issuance costs and debt discounts, partially offset by a net loss of $2.1 million and a $1.4 million use of cash from changes in operating assets and liabilities. The change in operating assets and liabilities was driven primarily by increases in inventory and accounts receivable to support our operations.
Cash used in operating activities for the six months ended June 30, 2025 totaled $0.5 million. This primarily reflected a net loss of $5.6 million, partially offset by non-cash charges of $3.9 million related to the change in fair value of derivative liabilities, $2.1 million of stock-based compensation expense, and $1.1 million related to amortization of debt issuance costs and debt discounts.
Cash Flows from Investing Activities
Cash used in investing activities for the six months ended June 30, 2026 totaled $0.6 million, consisting primarily of $0.4 million of purchases of property and equipment, including leasehold improvements at our headquarters, and $0.2 million of investment in capitalized software development.
Cash used in investing activities for the six months ended June 30, 2025 totaled $1.3 million, and consisted entirely of purchases of property and equipment of $1.3 million, of which $0.9 million was related to leasehold improvements at our new headquarters.
Cash Flows from Financing Activities
Cash used in financing activities for the six months ended June 30, 2026 totaled $2.8 million, consisting primarily of $2.9 million in scheduled quarterly principal payments on the Term Loan under the JPM Credit Agreement, partially offset by $0.1 million in proceeds from stock option exercises. The increase in financing cash outflows reflects the transition from our prior non-amortizing Senior Secured Debt to the Term Loan, which requires quarterly principal payments that commenced on December 31, 2025.
Cash provided by financing activities for the six months ended June 30, 2025 totaled $0.1 million, consisting of proceeds from stock option exercises, partially offset by payments on principal of finance leases.
Segment and Geographic Information
We have determined that we have one reportable 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 reportable segment, refer to Note 16 to the condensed consolidated financial statements.
Effects of Inflation
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 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 June 30, 2026. 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 June 30, 2026.
As of December 31, 2025, the Company identified the following material weaknesses which continue to exist as of June 30, 2026:
As previously disclosed, management has identified material weaknesses in the Company’s internal control over financial reporting primarily related to insufficient accounting resources and technical expertise to appropriately analyze and apply U.S. GAAP, as well as deficiencies in the design and implementation of business process controls, including those related to revenue recognition and sales tax, and information technology controls.
As a result of these material weaknesses, management concluded that the Company's internal control over financial reporting was not effective as of June 30, 2026. Management continues to evaluate and implement remediation measures designed to address these material weaknesses and strengthen the Company’s internal control environment.
Remediation Plan
Management is committed to remediating the material weaknesses in the Company’s internal control over financial reporting and has implemented and continues to implement measures designed to strengthen the control environment. These efforts include enhancing technical accounting resources, formalizing and expanding internal control procedures over financial reporting, and improving oversight and documentation of key control activities.
The Company has engaged external advisors to assist with technical accounting matters, including valuation analyses related to complex financial instruments and derivatives. In addition, the Company has implemented governance, risk, and compliance software to support control documentation, monitoring, and testing activities.
The Company also plans to further strengthen its control environment by adding personnel, improving segregation of duties, and enhancing information technology general controls, including controls over the Company’s enterprise resource planning systems. Management believes these actions will strengthen the Company’s internal control framework; however, the material weaknesses will not be considered remediated until the applicable controls have been designed, implemented,

and are operating effectively for a sufficient period, and management has concluded, through testing, that the controls are operating effectively.
Management will continue to evaluate and refine its remediation efforts and perform additional analyses and procedures to ensure that the Company’s consolidated financial statements are prepared in accordance with U.S. GAAP while remediation activities remain in progress.
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 stockholders 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 June 30, 2026, that materially affect, or are reasonably likely to materially affect, our internal control over financial reporting, except as disclosed in “Remediation Plan” above.
