Item 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the following risk factors and all other information contained in this Annual Report on Form 10-K, including the consolidated financial statements and the related notes, before purchasing our common stock. If any of the following risks actually occur, they may materially harm our business and our financial condition and results of operations. In any such event, the market price of our common stock could decline, and you could lose all or part of your investment.

Risks Related to our Business

We have identified material weaknesses in our internal control over financial reporting. If we are unable to remediate these material weaknesses, or if we identify additional material weaknesses in the future or otherwise fail to maintain effective internal control over financial reporting or disclosure controls and procedures, it may result in material misstatements of our consolidated financial statements or cause us to fail to meet our periodic reporting obligations, which may adversely affect our business, financial condition, and results of operations.

We have identified material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

We are taking certain measures to remediate these material weaknesses as discussed further in Part II, Item 9A of this Annual Report on Form 10-K; however, such material weaknesses had not been remediated as of December 31, 2025. In addition, due to the material weaknesses in internal control over financial reporting, we have also determined that our disclosure controls and procedures were not operating effectively as of December 31, 2025. The material weaknesses will not be considered remediated until management completes the design and implementation of the applicable controls, such controls have operated effectively for a sufficient period of time, and management has concluded, through testing, that these controls are operating effectively.

In connection with the preparation of our consolidated financial statements for the year ended December 31, 2025, we engaged a third party to conduct a sales and use tax nexus study. Management used this third party report and identified that we had a historical state and local sales tax liability related to prior periods. We are required and subject to collect and remit sales and use tax in state and local jurisdictions where we have economic and physical nexus. During the year ended December 31, 2025, we determined that a sales tax liability, related to the periods of 2022 through 2025, was probable and determined an estimated liability for sales transactions processed in jurisdictions where we had not previously reported. Management has concluded that the error was material to the previously issued annual financial statements and, accordingly, a restatement of prior period financial information was required in accordance with U.S. GAAP and SEC rules. For further information, refer to Note 2 to the consolidated financial statements.

There can be no assurance as to when the material weaknesses will be remediated. These remediation measures will be time consuming, will result in us incurring significant costs, and will place significant demands on our financial and operational resources.

We cannot assure that the measures we have taken to date and may take in the future will be sufficient to remediate the control deficiencies that led to our material weaknesses in internal control over financial reporting or that they will prevent potential future material weaknesses. The effectiveness of our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the possibility of human error, and the risk of fraud. Any failure to design, implement, and maintain effective internal control over financial reporting and effective disclosure controls and procedures, or any difficulties encountered in their implementation or improvement, could 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, financial condition, results of operations, and stock price.

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 loss (“NOL”) 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.

Our history of operating losses and prior reliance on external financing has raised, and could again raise, substantial doubt about our ability to continue as a going concern.

The Company has historically 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 year ended December 31, 2025, management executed a comprehensive refinancing of the Company’s secured debt with a new lender, which extended the maturity of the Company’s principal debt obligations and established a secured revolving credit facility. In addition, the Company generated net income of $11.8 million for the year ended December 31, 2025, and achieved positive operating income for both the years ended December 31, 2025, and December 31, 2024.

Management evaluated the Company’s financial condition and projected cash flows for the twelve months following the issuance of the consolidated financial statements included in this Annual Report on Form 10-K. Based on the debt refinancing, improved operating performance, and expected cash inflows from operations, we believe that our anticipated cash flows from operations, and cash on hand will be sufficient to satisfy our working capital needs, capital expenditures and debt repayments for at least twelve months from the issuance date of these consolidated financial statements.

However, there can be no assurance that the Company will continue to generate positive operating results or maintain sufficient liquidity in the future. Management will continue to monitor the Company’s financial position, operating results, and compliance with debt covenants. If the Company is unable to sustain improved operating performance, maintain access

17

to financing, or comply with applicable debt covenants, its financial condition and ability to continue operations could be materially adversely affected.

If we are unable to successfully raise additional capital, our viability may be threatened; however, if we do raise additional capital, your percentage ownership as a stockholder could decrease and constraints could be placed on the operations of our business.

Prior to 2025, we experienced negative operating cash flows and funded our operations primarily from proceeds received from sales of our capital stock, the issuance of promissory notes and convertible promissory notes, the issuance of notes payable to related parties, and product sales. We may seek to obtain additional funds in the future either through equity or debt financings or through strategic alliances with third parties, either alone or in combination with equity financings. These financings could result in substantial dilution to the holders of our common stock or require contractual or other restrictions on our operations or on alternative business opportunities that may be available to us. If we can raise additional funds by issuing debt securities, these debt securities could impose significant additional restrictions on our operations. Any such required financing may not be available in amounts or on terms acceptable to us, and the failure to procure such required financing could have a material adverse effect on our business, financial condition, and results of operations, or threaten our ability to continue as a going concern.

A variety of factors could impact our need to raise additional capital, the timing of any required financing and the amount of such financings. Factors that may cause our future capital requirements to be greater than anticipated or could accelerate our need for funds include, without limitation:

•unanticipated expenditures in research and development or manufacturing activities;

•unanticipated expenditures in the acquisition and defense of intellectual property rights;

•the failure to develop strategic alliances for the marketing of some of our products;

•unforeseen changes in healthcare reimbursement for procedures using any of our approved products;

•inability to train a sufficient number of physicians to create a demand for any of our approved products;

•lack of financial resources to adequately support our operations;

•difficulties in maintaining commercial scale manufacturing capacity and capability;

•unforeseen problems with our third-party manufacturers, service providers or specialty suppliers of certain raw materials;

•unanticipated difficulties in operating in international markets;

•unanticipated financial resources needed to respond to technological changes and increased competition;

•unforeseen problems in attracting and retaining qualified personnel;

•the impact of changes in U.S. health care law and policy on our operations;

•enactment of new legislation or administrative regulations;

•the application to our business of new court decisions and regulatory interpretations;

•claims that might be brought in excess of our insurance coverage;

•delays in timing of receipt of required regulatory approvals;

•the failure to comply with regulatory guidelines; and

•the uncertainty in industry demand and patient wellness behavior.

In addition, although we have no present commitments or understandings to do so, we may seek to expand our operations and product line through acquisitions. Any acquisition would likely increase our capital requirements.

The medical device/therapeutic product industries are highly competitive and subject to rapid technological change. If our competitors are better able to develop and market products that are safer and more effective than any products we may develop, our commercial opportunities will be reduced or eliminated.

Our success depends, in part, upon our ability to maintain a competitive position in the development of technologies and products. We face competition from established medical device, pharmaceutical and biotechnology companies, as well as from academic institutions, government agencies, and private and public research institutions in the United States and abroad. Many of our principal competitors have significantly greater financial resources and expertise than we do in research and development, manufacturing, pre-clinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements, or mergers with, or acquisitions by, large and established companies, or through the development of novel products and technologies. The industry in which we operate has undergone, and we

18

Table of Contents

expect it to continue to undergo, rapid and significant technological change, and we expect competition to intensify as technological advances are made.

Changes in reimbursement affecting the wound care market could adversely affect our customers and indirectly reduce demand for our products.

The wound care market is highly dependent on reimbursement from governmental and private third-party payors, including CMS and Medicare Administrative Contractors. CMS and other payors periodically revise coverage policies, payment levels, coding guidance, and utilization rules for wound care products and procedures, including cellular and tissue-based products for skin wounds ("skin substitutes" or allografts) and other advanced wound care therapies.

Although our UltraMIST system is not a skin substitute or allograft product, many of our customers operate within care settings where these products are frequently used as part of broader wound care treatment protocols. Significant reimbursement reductions or policy changes affecting such products or procedures could negatively affect the economics of wound care practices, hospitals, and other providers. These changes could reduce provider revenues, alter treatment protocols, or limit capital expenditures, which could indirectly reduce demand for our products.

Reimbursement policies are determined by governmental and private payers and are outside our control. Changes affecting the wound care reimbursement environment could adversely affect the financial condition of our customers and have a material adverse effect on our business, financial condition, and results of operations.

Many of our product component materials are only produced by a single supplier for such product component. If we are unable to obtain product component materials and other products from our suppliers that we depend on for our operations, or find suitable replacement suppliers, our ability to deliver our products to market will likely be impeded, which could have a material adverse effect on us.

We depend on suppliers for product component materials and other components that are subject to stringent regulatory requirements. Many of our product component materials are only produced by a single supplier for such product components. While we believe that alternative manufacturers and suppliers offering similar components are available on an as-needed basis and could be engaged in a reasonable period of time, there can be no assurance that the loss of these suppliers will not result in a disruption to our production. Our suppliers may encounter problems during manufacturing due to a variety of reasons, including failure to follow specific protocols and procedures, failure to comply with applicable regulations, equipment malfunction and environmental factors. Certain of our suppliers must be approved by regulatory authorities, which could delay our efforts to establish additional or replacement suppliers for these materials.

If we are unable to secure, on a timely basis, sufficient quantities of the materials we depend on to manufacture our products, if we encounter delays or contractual or other difficulties in our relationships with these suppliers, or if we cannot find replacement suppliers at an acceptable cost, the manufacturing of our products may be disrupted, which could increase our costs and have a material adverse effect on our business and results of operations.

The loss of our key management would likely hinder our ability to execute our business plan.

As a small company with fewer than 60 employees, our success depends on the continuing contributions of our management team and qualified personnel. Turnover, transitions or other disruptions in our management team and personnel could make it more difficult to successfully operate our business and achieve our business goals and could adversely affect our results of operation and financial condition. Our success depends in large part on our ability to attract and retain highly qualified personnel. We face intense competition in our hiring efforts from other pharmaceutical, biotechnology and medical device companies, as well as from universities and nonprofit research organizations, and we may have to pay higher salaries to attract and retain qualified personnel. The loss of one or more of these individuals, or our inability to attract additional qualified personnel, could substantially impair our ability to implement our business plan.

We face an inherent risk of liability if the use or misuse of our products results in personal injury or death.

The sale of products may expose us to product liability claims which could result in financial loss. Our clinical and commercial product liability insurance coverage may not be sufficient to cover claims that may be made against us. In addition, we may not be able to maintain insurance coverage at a reasonable cost, or in sufficient amounts or scope, to protect us against losses. Any claims against us, regardless of their merit, could severely harm our financial condition, strain our management team and other resources, and adversely impact or eliminate the prospects for commercialization of

19

Table of Contents

the product candidate, or sale of the product, that is the subject of any such claim. Although we do not promote any off-label use, off-label uses of products are common, and the FDA does not regulate a physician’s choice of treatment. Off-label uses of any of our products may subject us to additional liability.

We are dependent on information technology and our systems and infrastructure face certain risks, including from cybersecurity breaches and data leakage.

We rely to a large extent upon sophisticated information technology systems to operate our businesses, some of which are managed, hosted, provided and/or used by third parties or their vendors. We collect, store, and transmit large amounts of confidential information, and we deploy and operate an array of technical and procedural controls to maintain the confidentiality and integrity of such confidential information. A significant breakdown, invasion, corruption, destruction or interruption of critical information technology systems or infrastructure, by our workforce, others with authorized access to our systems or unauthorized persons could negatively impact our operations. The ever-increasing use and evolution of technology, including cloud-based computing, creates opportunities for the unintentional dissemination or intentional destruction of confidential information stored in our or our third-party providers’ systems, portable media, or storage devices. We could also experience, and in some cases have experienced in the past, a business interruption, theft of confidential information, financial theft, or reputational damage from industrial espionage attacks, malware, spoofing or other cyber-attacks, which may compromise our system infrastructure, lead to data leakage, either internally or at our third-party providers, or materially adversely impact our financial condition.

We have previously disclosed that we have experienced cybersecurity breaches from email spoofing. While we have invested in the protection of data and information technology, there can be no assurance that our efforts will prevent service interruptions or security breaches. Any such interruption or breach of our systems could adversely affect our business operations and/or result in the loss of critical or sensitive confidential information or intellectual property, and could result in financial, legal, business, and reputational harm to us.

If we are unable to expand, manage and maintain our direct sales and marketing organizations, we may not be able to generate anticipated revenue.

Building the requisite sales, marketing and distribution capabilities to successfully market and sell our products continues to be expensive and time-consuming and requires significant attention from our leadership team to manage. Any failure or delay in the expansion of our sales, marketing or distribution capabilities would adversely impact the commercialization of our products. Additionally, we may choose to collaborate, either globally or on a territory-by-territory basis, with third parties on the commercialization of our products. If we are unable to enter into arrangements with such third parties on acceptable terms or at all, we may not be able to successfully commercialize our products.

If we fail to properly manage our growth effectively, our business could suffer.

We intend to continue to grow and may experience periods of rapid growth and expansion, which could place a significant additional strain on our limited personnel, information technology systems and other resources including but not limited to procuring sufficient office, warehouse, and production space to successfully operate our business and the inherent difficulties arising from acquiring, managing, or moving between such operating spaces. In particular, the hiring of our direct sales force requires significant management, financial and other supporting resources. Any failure by us to manage our growth effectively could have an adverse effect on our ability to achieve our development and commercialization goals.

To achieve our revenue goals, we must continue to successfully increase manufacturing output to meet expected customer demand. We may experience difficulties with manufacturing yields, quality control, component supply and shortages of qualified personnel, such as skilled operators who can assemble our product, among other problems. Any of these problems could result in delays in product availability and increases in expenses. Any such delay or increased expense could adversely affect our ability to generate revenue.

Future growth will continue to impose significant added responsibilities on management, including the need to identify, recruit, train and integrate additional employees. In addition, rapid and significant growth will place a strain on our administrative and operational infrastructure.

In order to manage our operations and growth, we will need to continue to improve our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable to manage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and may have an adverse effect on our business, financial condition, and results of operations.

We generate a portion of our revenue internationally and are subject to various risks relating to our international activities, which could adversely affect our operating results.

On an annual basis, less than one percent of our revenue comes from international sources. While we have no current plan to materially expand our international operations, there can be no assurance we will not pursue such an expansion in the future. Engaging in international business involves several difficulties and risks, including, but not limited to, the following:

•required compliance with existing and changing foreign healthcare and other regulatory requirements and laws, such as those relating to patient privacy or handling of bio-hazardous waste;

•required compliance with anti-bribery laws, data privacy requirements, labor laws and anti-competition regulations;

•export or import restrictions;

•political and economic instability,

•foreign exchange controls; and

•difficulties protecting or procuring intellectual property rights.

With respect to our international operations, our results of operations and cash flows are subject to fluctuations due to changes in foreign currency exchange rates. Our expenses are generally denominated in the currencies in which our operations are located, which is in the United States. If the value of the U.S. dollar increases relative to foreign currencies in the future, in the absence of a corresponding change in local currency prices, our future revenue could be adversely affected as we convert future revenue from local currencies to U.S. dollars.

Provisions in our Articles of Incorporation, Bylaws and Nevada law might decrease the chances of an acquisition.

Provisions of our Articles of Incorporation and Bylaws and applicable provisions of Nevada law may delay or discourage transactions involving an actual or potential change in control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Some of the following provisions in our Articles of Incorporation or Bylaws that may decrease our attractiveness to be acquired are:

•advance notice of business to be brought is required for a meeting of our stockholders;

•the affirmative vote of the holders of at least sixty-six and two-thirds percent of the Company’s outstanding voting power is required for stockholders to amend our Bylaws;

•stockholders are prohibited from requesting or calling a special meeting of stockholders;

•no cumulative voting rights for the holders of common stock in the election of directors; and

•vacancies in the board of directors may be filled by a majority vote of the directors then in office or by a sole remaining director, in either case though less than a quorum.

In addition, Section 78.438 of the Nevada Revised Statutes prohibits a publicly-held Nevada corporation from engaging in a business combination with an interested stockholder (generally defined as a person which together with its affiliates owns, or within the last three years has owned, 10% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder) unless the business combination is approved in a prescribed manner. The existence of the foregoing provisions and other potential anti-takeover measures could limit the price that investors might be willing to pay in the future for shares of our common stock. They could also deter potential acquirers of our Company, thereby reducing the likelihood that you could receive a premium for your common stock in an acquisition.

Regulatory Risks

We are subject to extensive governmental regulation, including the FDA.

We and our products, our suppliers, and our contract manufacturers are subject to extensive regulation by governmental authorities in the United States and other countries. Failure to comply with applicable requirements could result in, among other things, any of the following actions:

•warning letters,

•fines and other monetary penalties,

21

Table of Contents

•unanticipated expenditures,

•product recall or seizure,

•interruption of manufacturing,

•operating restrictions,

•injunctions, and

•criminal prosecutions.

In addition to the approval and clearance requirements, numerous other regulatory requirements apply to us and our products, our suppliers and contract manufacturers. These include requirements related to the following:

•testing,

•manufacturing,

•quality control,

•labeling,

•advertising,

•promotion,

•distribution,

•export,

•reporting to the FDA certain adverse experiences associated with the use of the products, and

•obtaining additional approvals or clearances for certain modifications to the products or their labeling or claims.

We are also subject to inspection by the FDA and other international regulatory bodies to determine our compliance with regulatory requirements, as are our suppliers and contract manufacturers, and we cannot be sure that the FDA and other international regulatory bodies will not identify compliance issues that may disrupt production or distribution or require substantial resources to correct.

The FDA’s requirements and international regulatory body requirements may change, and additional regulations may be promulgated that could affect us, our products, and our suppliers and contract manufacturers. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action. There can be no assurance that we will not be required to incur significant costs to comply with such laws and regulations in the future, or that such laws or regulations will not have a material adverse effect upon our business.

Regulatory approval of our products may be withdrawn at any time.

After regulatory approval has been obtained for medical device products, the product and the manufacturer are subject to continual review, including the review of adverse experiences and clinical results that are reported after our products are made available to patients, and there can be no assurance that such approval will not be withdrawn or restricted. Regulators may also subject approvals to restrictions or conditions or impose post-approval obligations on the holders of these approvals, and the regulatory status of such products may be jeopardized if such obligations are not fulfilled. If post-approval studies are required, such studies may involve significant time and expense.

The manufacturing facilities we use to make any of our products will also be subject to periodic review and inspection by the FDA or other regulatory authorities, as applicable. The discovery of any new or previously unknown problems with the product or facility may result in restrictions on the product or facility, including withdrawal of the product from the market. We will continue to be subject to the FDA or other regulatory authority requirements, as applicable, governing the labeling, packaging, storage, advertising, promotion, recordkeeping, and submission of safety and other post-market information for all of our products, even those that the FDA or other regulatory authority, as applicable, had approved. If we fail to comply with applicable continuing regulatory requirements, we may be subject to fines, suspension or withdrawal of regulatory approval, product recalls and seizures, operating restrictions and other adverse consequences.

If we fail to obtain an adequate level of reimbursement for our approved products by third party payors, there may be no commercially viable markets for our approved products, or the markets may be much smaller than expected.

The availability and levels of reimbursement by governmental and other third-party payors affect the market for our approved products. The efficacy, safety, performance, and cost-effectiveness of our products, and of any competing products will determine the availability and level of reimbursement. Reimbursement and healthcare payment systems in international markets vary significantly by country and include both government sponsored healthcare and private insurance. To obtain reimbursement or pricing approval in some countries, we may be required to produce clinical data,

22

Table of Contents

which may involve one or more clinical trials, that compares the cost-effectiveness of our approved products to other available therapies. We may not obtain international reimbursement or pricing approvals in a timely manner, if at all. Our failure to receive international reimbursement or pricing approvals would negatively impact market acceptance of our approved products in the international markets in which those pricing approvals are sought.

We believe that, in the future, reimbursement for any of our products may be subject to increased restrictions both in the United States and in international markets. Future legislation, regulation or reimbursement policies of third-party payors may adversely affect the demand for our products currently under development and limit our ability to sell our products on a profitable basis. In addition, third-party payors continually attempt to contain or reduce the costs of healthcare by challenging the prices charged for healthcare products and services. If reimbursement for our approved products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, market acceptance of our approved products would be impaired and our future revenues, if any, would be adversely affected.

Failure to obtain regulatory approval in foreign jurisdictions will prevent us from marketing our products abroad.

International sales of our products that we commercialize are subject to the regulatory requirements of each country in which the products are sold. Accordingly, the introduction of our products in markets outside the United States will be subject to regulatory approvals in those jurisdictions. The regulatory review process varies from country to country. Many countries impose product standards, packaging, and labeling requirements, and import restrictions on medical devices. In addition, each country has its own tariff regulations, duties, and tax requirements. The approval by foreign government authorities is unpredictable and uncertain and can be expensive. Our ability to market our approved products could be substantially limited due to delays in receipt of, or failure to receive, the necessary approvals or clearances.

Prior to marketing our products in any country outside the United States, we must obtain marketing approval in that country. Approval and other regulatory requirements vary by jurisdiction and differ from the United States’ requirements. We may be required to perform additional pre-clinical or clinical studies even if FDA approval has been obtained.

Uncertainty surrounding and future changes to healthcare law in the United States may have a material adverse effect on us.

The healthcare regulatory environment in the United States is currently subject to significant uncertainty and the industry may in the future continue to experience fundamental change because of regulatory reform. From time to time, legislation is drafted and introduced in the United States Congress that could significantly change the statutory provisions governing the clearance or approval, manufacture, marketing, and pricing of medical devices. In addition, FDA regulations and guidance are often revised or reinterpreted by the agency in ways that may significantly affect our business and our products. We could experience an adverse impact on our operating results due to such changes, including increased pricing pressure in these markets. Governments, hospitals, and other third-party payers also could reduce the amount of approved reimbursement for our products or deny coverage altogether. Reductions in reimbursement levels or coverage or other cost-containment measures could adversely affect our future operating results.

If we fail to comply with the United States Federal Anti-Kickback Statute, False Claims Act, and similar state laws, we could be subject to criminal and civil penalties and exclusion from the Medicare and Medicaid programs, which would have a material adverse effect on our business and results of operations.

A provision of the Social Security Act, commonly referred to as the Federal Anti-Kickback Statute, prohibits the offer, payment, solicitation, or receipt of any form of remuneration in return for referring, ordering, leasing, purchasing or arranging for, or recommending the ordering, purchasing or leasing of, items or services payable by Medicare, Medicaid or any other Federal healthcare program. The Federal Anti-Kickback Statute is very broad in scope and many of its provisions have not been uniformly or definitively interpreted by existing case law or regulations. In addition, most of the states have adopted laws like the Federal Anti-Kickback Statute, and some of these laws are even broader than the Federal Anti-Kickback Statute in that their prohibitions are not limited to items or services paid for by Federal healthcare programs, but instead apply regardless of the source of payment. Violations of the Federal Anti-Kickback Statute may result in substantial civil or criminal penalties and exclusion from participation in Federal healthcare programs.

Our operations may also implicate the False Claims Act. If we fail to comply with Federal and state documentation, coding, and billing rules, we could be subject to liability under the Federal False Claims Act, including criminal and/or civil penalties, loss of licenses and exclusion from the Medicare and Medicaid programs. The False Claims Act prohibits

23

Table of Contents

individuals and companies from knowingly submitting false claims for payments to, or improperly retaining overpayments from, the government.

Our financial relationships with healthcare providers and others who provide products or services to Federal healthcare program beneficiaries are potentially governed by the Federal Anti-Kickback Statute, False Claims Act, and similar state laws. We cannot be certain that we will not be subject to investigations or litigation alleging violations of these laws, which could be time-consuming and costly to us and could divert management’s attention from operating our business, which in turn could have a material adverse effect on our business. In addition, if our arrangements were found to violate the Federal Anti-Kickback Statute, False Claims Act or similar state laws, the consequences of such violations would likely have a material adverse effect on our business, results of operations and financial condition.

Failure to comply with the HIPAA and state-specific privacy laws, as such rules become applicable to our business, may increase our operational costs.

The HIPAA privacy and security regulations establish comprehensive Federal standards with respect to the uses and disclosures of PHI by certain entities, including health plans and health care providers, and set standards to protect the confidentiality, integrity, and availability of electronic PHI. The regulations establish a complex regulatory framework on a variety of subjects, including, for example: the circumstances under which uses and disclosures of PHI are permitted or required without a specific authorization by the patient; a patient’s right to access, amend and receive an accounting of certain disclosures of PHI; the content of notices of privacy practices describing how PHI is used and disclosed and individuals’ rights with respect to their PHI; and implementation of administrative, technical and physical safeguards to protect privacy and security of PHI. We anticipate that, as we expand our business, we will in the future be a covered entity under HIPAA. There can be no assurance that our policies and procedures will be adequate or will prevent all incidents of non-compliance with such regulations.

The HITECH Act and its implementing regulations also require healthcare providers to notify affected individuals, the Secretary of the U.S. Department of Health and Human Services, and in some cases, the media, when PHI has been breached as defined under and following the requirements of HIPAA. Many states have similar breach notification laws. In the event of a breach, to the extent such regulations are applicable to our business, we could incur operational and financial costs related to remediation as well as preparation and delivery of the notices, which costs could be substantial. Additionally, HIPAA, the HITECH Act, and their implementing regulations provide for significant civil fines, criminal penalties, and other sanctions for failure to comply with the privacy, security, and breach notification rules, including for wrongful or impermissible use or disclosure of PHI. Although the HIPAA statute and regulations do not expressly provide for a private right of action for damages, private parties may also seek damages under state laws for the wrongful or impermissible use or disclosure of confidential health information or other private personal information. Additionally, amendments to HIPAA provide that the state attorneys general may bring an action against a covered entity for a violation of HIPAA. As we expand our business such that Federal laws regarding PHI and privacy apply to our operations, any noncompliance with such regulations could have a material adverse effect on our business, results of operations and financial condition.

In addition to our obligations under HIPAA, many states have laws that govern the processing, collection, use, disclosure, transfer, storage, disposal and protection of health-related and other sensitive and personal information. These state law protections are different and, in some cases, may be more stringent, broader in scope, or offer greater individual rights with respect to sensitive health information than HIPAA. These laws are evolving rapidly and may differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts. Such laws and regulations will be subject to interpretation by various courts and other governmental authorities, thus creating potentially complex compliance issues for us and our future customers and strategic partners. Failure to comply with these laws, where applicable, can result in the imposition of significant civil and/or criminal penalties and private litigation. In addition to the state comprehensive data privacy laws, recent years have brought substantial changes to the federal and state treatment of non-HIPAA consumer health information. At the federal level, the FTC brought three enforcement actions in 2023 against a range of companies that handle electronic health information relating to collection and disclosure of non-HIPAA covered consume health information under Section 5 of the FTC Act, two of which included allegations made under the FTC’s HBNR. The FTC’s focus on health information continued in 2024 with changes to the HBNR that clarified its scope and emphasized applicability to non-HIPAA health care providers as well as three additional enforcement actions against companies for their use of health information for advertising purposes. On the state level, Washington and Nevada have adopted significant new legislation addressing businesses treatment of consumer health information, and Connecticut added more stringent protections for health information to its existing comprehensive state privacy law. In both Washington and Nevada’s laws, there are restrictive provisions limiting collection and disclosure of consumer health information, and

24

Table of Contents

Washington’s law provides a separate private right of action for violations. Any noncompliance with applicable laws or regulations could have a material adverse effect on our business, results of operations and financial condition.

We face periodic reviews and billing audits from governmental and private payors, and these audits could have adverse results that may negatively impact our business.

As a result of our participation in the Medicare and Medicaid programs, we are subject to various governmental reviews and audits to verify our compliance with these programs and applicable laws and regulations. We also are subject to audits under various government programs in which third-party firms engaged by the CMS conduct extensive reviews of claims data and medical and other records to identify potential improper payments under the Medicare program. Private pay sources also reserve the right to conduct audits. If billing errors are identified in the sample of reviewed claims, the billing error can be extrapolated to all claims filed, which could result in a larger overpayment than originally identified in the sample of reviewed claims. Our costs to respond to and defend reviews and audits may be significant and could have a material adverse effect on our business, financial condition, results of operations and cash flows. Moreover, an adverse review or audit could result in:

•required refunding or retroactive adjustment of amounts we have been paid by governmental or private payors;

•state or Federal agencies imposing fines, penalties and other sanctions on us;

•loss of our right to participate in the Medicare program, state programs, or one or more private payor networks; or

•damage to our business and reputation in various markets.

Any one of these results could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Product quality or performance issues may be discovered through ongoing regulation by the FDA and by comparable international agencies, as well as through our internal standard quality process.

The medical device industry is subject to substantial regulation by the FDA and by comparable international agencies. In addition to requiring clearance or approval to market new or improved devices, we are subject to ongoing regulation as a device manufacturer. Governmental regulations cover many aspects of our operations, including quality systems, marketing and device reporting. As a result, we continually collect and analyze information about our product quality and product performance through field observations, customer feedback and other quality metrics. If we fail to comply with applicable regulations or if post market safety issues arise, we could be subject to enforcement sanctions, our promotional practices may be restricted, and our marketed products could be subject to recall or otherwise impacted. Each of these potential actions could result in a material adverse effect on our business, operating results and financial condition.

The use of hazardous materials in our operations may subject us to environmental claims or liability.

We conduct research and development and manufacturing operations in our facility. Our research and development process may, at times, involve the controlled use of hazardous materials and chemicals. We may conduct experiments in which we may use small quantities of chemicals, including those that are corrosive, toxic, and flammable. The risk of accidental injury or contamination from these materials cannot be eliminated. We do not maintain a separate insurance policy for these types of risks. In the event of an accident or environmental discharge or contamination, we may be held liable for any resulting damages, and any liability could exceed our resources. We are subject to Federal, state, and local laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. The cost of compliance with these laws and regulations could be significant.

Risks Related to Intellectual Property

The protection of our intellectual property is critical to our success, and any failure on our part to adequately protect those rights could materially adversely affect our business.

Our commercial success depends to a significant degree on our ability to:

•obtain and/or maintain protection for our products under the patent laws of the United States and other countries;

•defend and enforce our patents once obtained;

•obtain and/or maintain appropriate licenses to patents, patent applications or other proprietary rights held by others with respect to our technology, both in the United States and other countries;

25

Table of Contents

•maintain trade secrets and other intellectual property rights relating to our products; and

•operate without infringing upon the patents, trademarks, copyrights, and proprietary rights of third parties.

The degree of intellectual property protection for our technology is uncertain, and only limited intellectual property protection may be available for our products, which may prevent us from gaining or keeping any competitive advantage against our competitors. Although we believe the patents that we own or license, and the patent applications that we own, generally provide us a competitive advantage, the patent positions of biotechnology, biopharmaceutical and medical device companies are generally highly uncertain, involve complex legal and factual questions and have been the subject of much litigation. Neither the United States Patent & Trademark Office nor the courts have a consistent policy regarding the breadth of claims allowed or the degree of protection afforded under many biotechnology patents. Even if issued, patents may be challenged, narrowed, invalidated, or circumvented, which could limit our ability to stop competitors from marketing similar products or limit the length of term of patent protection we may have for our products. Further, a court or other government agency could interpret our patents in a way such that the patents do not adequately cover our current or future products. Changes in either patent laws or in interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property or narrow the scope of our patent protection.

We also rely upon trade secrets and unpatented proprietary know-how and continuing technological innovation in developing our products, especially where we do not believe patent protection is appropriate or obtainable. We seek to protect this intellectual property, in part, by generally requiring our employees, consultants, and current and prospective business partners to enter into confidentiality agreements in connection with their employment, consulting or advisory relationships with us, where appropriate. We also require our employees, consultants, researchers, and advisors who we expect to work on our products to agree to disclose and assign to us all inventions conceived during the workday, developed using our property or which relate to our business. We may lack the financial or other resources to successfully monitor and detect, or to enforce our rights in respect of, infringement or breaches of these confidentiality agreements. In the case of any such undetected or unchallenged infringements or breaches, these confidentiality agreements may not provide us with meaningful protection of our trade secrets and unpatented proprietary know-how or adequate remedies. In addition, others may independently develop technology that is similar or equivalent to our trade secrets or know-how. If any of our trade secrets, unpatented know-how or other confidential or proprietary information is divulged to third parties, including our competitors, our competitive position in the marketplace could be harmed and our ability to sell our products successfully could be severely compromised. Enforcing a claim that a party illegally obtained and is using trade secrets that have been licensed to us or that we own is also difficult, expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States may be less willing to protect trade secrets. Costly and time-consuming litigation could be necessary to seek to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could have a material adverse effect on our business. Moreover, some of our academic institution licensees, evaluators, collaborators, and scientific advisors have rights to publish data and information to which we have rights. If we cannot maintain the confidentiality of our technologies and other confidential information in connection with our collaborations, our ability to protect our proprietary information or obtain patent protection in the future may be impaired, which could have a material adverse effect on our business.

Accordingly, we may fail to secure meaningful patent protection relating to any of our existing or future products or discoveries despite the expenditure of considerable resources. Further, there may be widespread patent infringement in countries in which we may seek patent protection, including countries in Europe and Asia, which may instigate expensive and time-consuming litigation that could adversely affect the scope of our patent protection. In addition, others may attempt to commercialize products similar to our products in countries where we do not have adequate patent protection. Failure to obtain adequate patent protection for our products, or the failure by particular countries to enforce patent laws or allow prosecution for alleged patent infringement, may impair our ability to be competitive. The availability of infringing products in markets where we have patent protection, or the availability of competing products in markets where we do not have adequate patent protection, could erode the market for our products, negatively impact the prices we can charge for our products, and harm our reputation if infringing or competing products are manufactured to inferior standards.

Patent applications owned by us or licensed to us may not result in issued patents, and our competitors may commercialize the discoveries we attempt to patent.

The patent applications that we own and that have been licensed to us, and any future patent applications that we may own or that may be licensed to us, may not result in the issuance of any patents. The standards that the United States Patent & Trademark Office and foreign patent agencies use to grant patents are not always applied predictably or uniformly and can change. Consequently, we cannot be certain as to the type and scope of patent claims to which we may in the future be entitled under our license agreements or that may be issued to us. These applications may not be sufficient to meet the

26

Table of Contents

statutory requirements for patentability and, therefore, may not result in enforceable patents covering the products we want to commercialize. Further, patent applications in the United States that are not filed in other countries may not be published or generally are not published until at least 18 months after they are first filed, and patent applications in certain foreign countries generally are not published until many months after they are filed. Scientific and patent publication often occurs long after the date of the scientific developments disclosed in those publications. As a result, we cannot be certain that we will be the first creator of inventions covered by our patents or applications, or the first to file such patent applications. As a result, our issued patents and our patent applications could become subject to challenge by third parties that created such inventions or filed patent applications before us or our licensors, resulting in, among other things, interference proceedings in the United States Patent & Trademark Office to determine priority of discovery or invention. Interference proceedings, if resolved adversely to us, could result in the loss of or significant limitations on patent protection for our products or technologies. Even in the absence of interference proceedings, patent applications now pending or in the future filed by third parties may prevail over the patent applications that may be owned by us or licensed to us or that we may file in the future, or may result in patents that issue alongside patents issued to us or our licensors or that may be issued or licensed to us in the future, leading to uncertainty over the scope of the patents owned by us or licensed to us or that may in the future be owned by us or impede our freedom to practice the claimed inventions.

Our patents may not be valid or enforceable and may be challenged by third parties.

We cannot assure you that the patents that have been issued or licensed to us would be held valid by a court or administrative body or that we would be able to successfully enforce our patents against infringers, including our competitors. The issuance of a patent is not conclusive as to its validity or enforceability, and the validity and enforceability of a patent is susceptible to challenge on numerous legal grounds, including the possibility of reexamination proceedings brought by third parties in the United States Patent & Trademark Office against issued patents and similar validity challenges under foreign patent laws. Challenges raised in patent infringement litigation brought by us or against us may result in determinations that patents that have been issued to us or licensed to us or any patents that may be issued to us or our licensors in the future are invalid, unenforceable or otherwise subject to limitations. In the event of any such determinations, third parties may be able to use the discoveries or technologies claimed in these patents without paying licensing fees or royalties to us, which could significantly diminish the value of our intellectual property and our competitive advantage. Even if our patents are held to be enforceable, others may be able to design around our patents or develop products similar to our products that are not within the scope of any of our patents.

In addition, enforcing the patents that we own or license and any patents that may be issued to us in the future against third parties may require significant expenditures regardless of the outcome of such efforts. Our inability to enforce our patents against infringers and competitors may impair our ability to be competitive and could have a material adverse effect on our business.

Issued patents and patent licenses may not provide us with any competitive advantage or provide meaningful protection against competitors.

The discoveries or technologies covered by issued patents we own or license may not have any value or provide us with a competitive advantage, and many of these discoveries or technologies may not be applicable to our products at all. We have devoted limited resources to identifying competing technologies that may have a competitive advantage relative to ours, especially those competing technologies that are not perceived as infringing on our intellectual property rights. In addition, the standards that courts use to interpret and enforce patent rights are not always applied predictably or uniformly and can change, particularly as new technologies develop. Consequently, we cannot be certain as to how much protection, if any, will be afforded by these patents with respect to our products if we, our licensees or our licensors attempt to enforce these patent rights and those rights are challenged in court.

The existence of third-party patent applications and patents could significantly limit our ability to obtain meaningful patent protection. If patents containing competitive or conflicting claims are issued to third parties, we may be enjoined from pursuing research, development or commercialization of product candidates or may be required to obtain licenses, if available, to these patents or to develop or obtain alternative technology. If another party controls patents or patent applications covering our product candidates, we may not be able to obtain the rights we need to those patents or patent applications in order to commercialize our product candidates or we may be required to pay royalties, which could be substantial, to obtain licenses to use those patents or patent applications.

27

Table of Contents

In addition, issued patents may not provide commercially meaningful protection against competitors. Other parties may seek and/or be able to duplicate, design around or independently develop products having effects similar or identical to our patented products that are not within the scope of our patents.

Limitations on patent protection in some countries outside the United States, and the differences in what constitutes patentable subject matter in these countries, may limit the protection we have under patents issued outside of the United States. We do not have patent protection for our product candidates in several of our target markets. The failure to obtain adequate patent protection for our products in any country would impair our ability to be commercially competitive in that country.

The ability to market the products we develop is subject to the intellectual property rights of third parties.

The biotechnology, biopharmaceutical and medical device industries are characterized by many patents and patent filings and frequent litigation based on allegations of patent infringement. Competitors may have filed patent applications or have been issued patents and may obtain additional patents and proprietary rights related to products or processes that compete with or are similar to ours. We may not be aware of all the patents potentially adverse to our interests that may have been issued to others. Because patent applications can take many years to issue, there may be currently pending applications, unknown to us, which may later result in issued patents that our products or proprietary technologies may infringe. Third parties may claim that our products or related technologies infringe their patents or may claim that the products of our suppliers, manufacturers or contract service providers that produce our devices infringe on their intellectual property. Further, we, our licensees, or our licensors, may need to participate in interference, opposition, protest, reexamination or other potentially adverse proceedings in the United States Patent & Trademark Office or in similar agencies of foreign governments with regards to our patents, patent applications, and intellectual property rights. In addition, we, our licensees, or our licensors may need to initiate suits to protect our intellectual property rights.

Litigation or any other proceeding relating to intellectual property rights, even if resolved in our favor, may cause us to incur significant expenses, divert the attention of our management and key personnel from other business concerns and, in certain cases, result in substantial additional expenses to license technologies from third parties. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. An unfavorable outcome in any patent infringement suit or other adverse intellectual property proceeding could require us to pay substantial damages, including possible treble damages and attorneys’ fees, cease using our technology or developing or marketing our products, or require us to seek licenses, if available, of the disputed rights from other parties and potentially make significant payments to those parties. There is no guarantee that any prevailing party would offer us a license or that we could acquire any license made available to us on commercially acceptable terms. Even if we can obtain rights to a third party’s patented intellectual property, those rights may be nonexclusive and, therefore, our competitors may obtain access to the same intellectual property. Ultimately, we may be unable to commercialize our products or may have to cease some of our business operations because of patent infringement claims, which could materially harm our business. We cannot guarantee that our products or technologies will not conflict with the intellectual property rights of others.

If we need to redesign our products to avoid third party patents, we may suffer significant regulatory delays associated with conducting additional clinical studies or submitting technical, clinical, manufacturing, or other information related to any redesigned product and, ultimately, in obtaining regulatory approval. Further, any such redesigns may result in less effective and/or less commercially desirable products if the redesigns are possible at all.

Additionally, any involvement in litigation in which we, or our licensees or our licensors, are accused of infringement may result in negative publicity about us or our products, injure our relations with any then-current or prospective customers and marketing partners, and cause delays in the commercialization of our products.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations provides information management believes to be relevant to understanding the financial condition and results of operations of the Company. The discussion focuses on our financial results of operations for the years ended December 31, 2025 and 2024. You should read this discussion and analysis in conjunction with our consolidated financial statements and related notes thereto for the years ended December 31, 2025, and 2024, which are presented within Part II, Item 8. "Financial Statements and Supplementary Data" in this Annual Report on Form 10-K. This discussion has been updated to reflect the restatement of our previously issued financial statements for the quarters ended March 31, June 30, September 30, 2025, and the year ended 2024. All amounts and discussions herein are based on the restated financial information. Refer to Note 2 to the consolidated financial statements for further details regarding the nature and impact of the restatement. Amounts reported in thousands within this annual report are computed based on the amounts in thousands, and therefore, the sum of the components may not equal the total amount reported in thousands due to rounding.

Executive Summary

We realized significant revenue growth during the year ended December 31, 2025, with a 35% growth in revenue to $44.1 million for the year ended December 31, 2025, as compared to $32.6 million in 2024. Gross margins also increased to 77% from 75% in 2024. As the Company continues to focus on profitable growth, we have also increased our operating income by 29% to $4.9 million for the year ended December 31, 2025, compared to $3.8 million for the year ended December 31, 2024.

Net income for the year ended December 31, 2025, was $11.8 million, or $1.38 per basic share and $0.41 per diluted share, compared to a net loss of $33.1 million, or $7.41 per basic and diluted share, for the year ended December 31, 2024, an increase of $44.9 million, which was largely driven by a non-cash change in the fair value of derivatives and improved operational performance. We believe these improvements set the stage for additional growth as we head into 2026.

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 income (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.

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.

31

Table of Contents

•Do not reflect interest expense, or the amount necessary to service our outstanding debt.

As presented in the GAAP to Non-GAAP Reconciliations section below, our non-GAAP financial measures exclude the impact of certain charges that contribute to our net income (loss).

For the Years Ended December 31,

Non-GAAP Adjustments:

Depreciation and amortization 1,265 1,145

Non-GAAP Adjustments for Adjusted EBITDA:

Change in fair value of derivative liabilities (8,107) 31,413

(in thousands) 2025 2024 (As Restated) $ %

Gross margin % 77 % 75 %

Operating expenses:

Revenue

Revenues for the year ended December 31, 2025 were $44.1 million, compared to $32.6 million for 2024, an increase of $11.4 million or 35%. The increase in revenue was primarily driven by higher sales volumes of UltraMIST® consumables and systems. The quantity of UltraMIST® consumables sold increased 24%, and UltraMIST® systems sold increased by 67% in 2025 compared to 2024.

Pricing trends also contributed to year-over-year performance. The average selling price of UltraMIST® consumables increased 3% in 2025 compared to2024. In contrast, the average selling price of UltraMIST® systems declined by 3%, primarily due to a higher proportion of sales through resellers. UltraMIST® systems sold through resellers comprised 34% of system sales in 2025 compared to no reseller system sales in 2024. Expanding reseller sales supports faster placement of systems into customer facilities and contributes to growth in our active system base.

Cost of Revenue

Cost of revenues for the year ended December 31, 2025 were $10.1 million, compared to $8.1 million for 2024. Gross profit as a percentage of revenues was 77% for the year ended December 31, 2025, compared to 75% for the same period in 2024. This increase in gross margin was largely driven by increased pricing on our UltraMIST® consumables and reductions in system cost of revenue, partially offset by a decrease in UltraMIST® system pricing, largely resulting from a higher reseller mix. The average gross profit of systems sold increased 0.1% in 2025 compared to 2024.

General and Administrative

General and administrative expenses for the year ended December 31, 2025 were $19.4 million as compared to $12.9 million for 2024, an increase of $6.5 million, or 50%. The increase in 2025 as compared to 2024 was primarily due to increased headcount expenses of $2.7 million, non-cash charges for stock-based compensation totaling $2.4 million, software expenses of $0.4 million, audit and tax professional expenses of $0.2 million, and public company costs of $0.2 million.

Selling and Marketing

Selling and marketing expenses for the year ended December 31, 2025 were $7.4 million as compared to $6.3 million for 2024, an increase of $1.1 million, or 17%. The year-over-year increase in sales and marketing expenses in 2025, was primarily driven by increased headcount expenses of $1.9 million, non-cash charges for stock-based compensation totaling $0.8 million, and consulting expenses of $0.5 million, partially offset by a decrease in outside commission expense of $1.9 million as our focus shifted toward a higher mix of resellers versus distributors.

Research and Development

Research and development expenses for the year ended December 31, 2025 were $1.4 million, compared to $0.7 million for 2024. The increase in research and development costs in 2025 as compared to 2024, was largely driven by research and development (R&D) project expenses totaling $0.2 million, consulting expenses of $0.2 million, and patent legal fees of $0.2 million.

Other Income (Expense), net

Other income (expense), net consists of the following:

For the Years Ended December 31, Change

Loss on impairment of assets (196) - (196) -%

Total other income for the year ended December 31, 2025 was$7.0 million, as compared to an expense of $36.9 million for 2024, an increase of $43.9 million. The increase was primarily driven by the change in fair value of derivative liabilities of $39.5 million, interest expense reduction of $7.5 million, and an other income increase of $3.0 million, partially offset by a change in the gain (loss) on extinguishment of debt of $6.8 million. The change in fair value of derivative liability relates to the valuation of warrants previously issued by the Company. The reduction in interest expense is due to the conversion of previously issued notes that were exchanged for common stock in October 2024 as described in Note 13 of our consolidated financial statements, as well as a reduction in interest rate from the repayment of our Senior Secured Debt and issuance of our Term Loan as described in Note 9 of our consolidated financial statements. Other income for 2025 mainly consists of the one-time payment of $5.0 million related to the patent purchase agreement as described in Note 20 of our consolidated financial statements. Other income for 2024 mainly consists of the one-time payment of $2.5 million related to the Patent License agreement as described in Note 20 of our consolidated financial statements.

Liquidity and Capital Resources

From inception through the year ended December 31, 2024, we incurred losses from operations each year. As of December 31, 2025, we had an accumulated deficit of $242.7 million. Historically, our operations have primarily been funded from the sale of capital stock, and 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 debt 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 our Quarterly Report on Form 10-Q for the quarter ended June 30, 2025.

Table of Contents

However, as described in Note 9 of our consolidated financial statements, we successfully refinanced our outstanding debt during 2025. The refinancing extended the maturity of our debt and provided the option for additional liquidity to support ongoing operations through the secured revolving credit facility. In addition, the operating income achieved in 2025, the receipt of $5.0 million from the patent purchase agreement as described in Note 20 of our consolidated financial statements, and the capital raised from a private placement in October 2024 as described in Note 14 of our consolidated financial statements, have all contributed to a significant improvement in our financial position.

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 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 9 of our consolidated financial statements, together with our recent operating income and capital initiatives, have significantly strengthened our ability to meet our obligations as they come due. 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.

The following table presents summarized cash flow information:

For the years ended December 31,

Cash flows provided by operating activities $ 3,876 $ 2,455

Cash flows provided by (used in) investing activities $ 3,433 $ (490)

Cash flows (used in) provided by financing activities $ (5,587) $ 6,354

Cash Flows from Operating Activities

Cash provided by operating activities for 2025 totaled $3.9 million. The primary source was net income of $11.8 million, adjusted for non-cash items including stock-based compensation expense of $4.9 million, amortization of debt issuance costs and debt discounts of $1.5 million, depreciation and amortization of $1.3 million, a $0.5 million inventory write-off related to the disposal of PACE, $0.6 million in tenant improvement allowances received, and $0.9 million of other non-cash items. These were partially offset by a non-cash gain of $8.1 million on the change in fair value of derivative liabilities, a $5.4 million non-cash gain on the sale of patents, and a $4.0 million net use of cash from changes in operating assets and liabilities, driven primarily by an increase in accounts receivable reflecting higher revenue activity and an increase in inventory due to a build up to support anticipated demand.

Cash provided by operating activities for 2024 totaled $2.5 million and consisted primarily of the change in fair value of derivative liabilities connected to our convertible debt and warrants issued. The Company recognized a loss on these liabilities of $31.4 million for the year ended December 31, 2024.

Cash Flows from Investing Activities

Cash provided by investing activities for 2025 totaled $3.4 million, consisting of $5.4 million in proceeds from the sale of patents, partially offset by $1.9 million in purchases of property and equipment.

Cash used in investing activities for 2024 totaled $0.5 million, consisting entirely of purchases of property and equipment.

Cash Flows Provided by Financing Activities

Cash used in financing activities for 2025 totaled $5.6 million, consisting primarily of $27.7 million in payments on notes payable, $1.4 million in repayment of principal on the secured term loan, $0.4 million in debt issuance costs, and $0.2 million in principal payments on finance leases, partially offset by $23.0 million in proceeds from a new secured term loan,

$0.7 million in proceeds from the secured revolving credit facility, and $0.6 million in proceeds from exercises of stock options.

Cash provided by financing activities for 2024 totaled $6.4 million, consisting primarily of $10.3 million in proceeds from the sale of common stock, $1.3 million in proceeds from convertible promissory notes, and $0.5 million from secured promissory notes payable from a related party, partially offset by $3.5 million in payments on notes payable, $0.5 million in repayments of secured promissory notes payable to a related party, $1.5 million in payments to factoring, and $0.2 million in principal payments on finance leases.

Critical Accounting Estimates

We consider an accounting estimate to be critical if: (1) the accounting estimate requires us to make assumptions about matters that were highly uncertain at the time the accounting estimate was made, and (2) changes in the estimate are reasonably likely to occur from period to period, or use of different estimates that we reasonably could have used in the current period, would have a material impact on our financial condition or results of operations.

Management has discussed the development and selection of these critical accounting estimates with the Audit Committee of our Board of Directors. In addition, there are other items within our consolidated financial statements that require estimation, but are not deemed critical as defined above. Changes in estimates used in these and other items could have a material impact on our consolidated financial statements.

We have used various accounting policies to prepare the 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 this Annual Report on Form 10-K.

The preparation of the 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 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.

The following accounting estimates are deemed critical:

Litigation Contingencies

We may be involved in legal actions involving product liability, intellectual property and commercial disputes, tax disputes, and governmental proceedings and investigations. The outcomes of these legal actions are not completely within our control and may not be known for prolonged periods of time. In some actions, the enforcement agencies or private claimants seek damages that could require significant expenditures or result in lost revenues or limit our ability to conduct business in the applicable jurisdictions. Estimating probable losses from our litigation and governmental proceedings is inherently difficult, particularly when the matters are in early procedural stages, with incomplete scientific facts or legal discovery; involve unsubstantiated or indeterminate claims for damages; potentially involve penalties, fines, or punitive damages; or could result in a change in business practice. The Company records a liability in the consolidated financial statements for loss contingencies when a loss is known or considered probable, and the amount may be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible but not known or probable, and may be reasonably estimated, the estimated loss or range of loss is disclosed. Our significant legal proceedings are discussed in Note 21 to the consolidated financial statements in Part II, Item 8. “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.

Sales Tax Nexus and Related Liabilities

During the fiscal year ended December 31, 2025, the Company completed its initial sales tax nexus study to evaluate its obligations to collect and remit sales tax across various state and local jurisdictions. Determining the extent of the Company's sales tax nexus requires significant judgment regarding the nature of the Company's business activities in each jurisdiction, the applicability of economic nexus thresholds, specific customers and their exempt status, the interpretation of

36

Table of Contents

state and local tax laws and regulations, which continue to evolve following South Dakota v. Wayfair, Inc. and subsequent legislative developments. This can cause changes in the widely acceptable administrative practices of jurisdictions.

The Company recorded a liability for estimated sales tax obligations, including potential interest and penalties, arising from both current and prior periods, when an exposure is considered probable and the amount can be reasonably estimated. Where the reasonable estimate of a probable liability is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. Reasonably possible exposures identified in the study that do not meet the threshold for accrual are disclosed when material. Given the inherent complexity of multistate tax compliance and the application of economic nexus rules, actual liabilities may differ materially from current estimates, depending on the outcome of ongoing or future reviews by state tax authorities. Such differences may have a material impact on the Company's financial condition, results of operations, or cash flows.

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 22 to the 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.

Recently Issued Accounting Standards

Information regarding new accounting pronouncements is included in Note 3 to the consolidated financial statements in Part II, Item 8. “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.

Item 7A. 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.

In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2025, and the consolidated results of its operations and its cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of SANUWAVE Health, Inc. (the “Company”) and Subsidiaries as of December 31, 2024, the related consolidated statements of comprehensive income (loss), stockholders’ equity (deficit), and cash flows for the year ended December 31, 2024, and the related notes (collectively referred to as the “financial statements”). In our opinion, based on our audit, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024, and the results of its operations and its cash flows for the year ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

Restatement of December 31, 2024 Financial Statements

As discussed in Note 2 to the financial statements, the accompanying financial statements as of and for the year ended December 31, 2024, have been restated to correct misstatements regarding accounting for state sales and use tax liability.

Explanatory Paragraph – Going Concern

The 2024 financial statements were prepared assuming that the Company would continue as a going concern. As of the date of the issuance of the 2024 financial statements, the Company had incurred recurring losses, had negative working capital, and needed to refinance its debt to meet its obligations and sustain its operations. These conditions raised substantial doubt about the Company's ability to continue as a going concern as of the date of the issuance of the 2024 financial statements. The 2024 financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

SANUWAVE HEALTH, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2025 and 2024

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 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”) and with the instructions to Form 10-K and Regulation S-X. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries.All significant intercompany accounts and transactions have been eliminated. Amounts reported in thousands within this annual report are computed based on the amounts in thousands, and therefore, the sum of the components may not equal the total amount reported in thousands due to rounding.

Use of Estimates - The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Foreign Currency Translation - The functional currencies of the Company’s foreign operations are their local currencies. The financial statements of the Company’s foreign subsidiary have been translated into United States dollars. All balance sheet accounts have been translated using the exchange rates in effect at the balance sheet date. Income statement amounts have been translated using the average exchange rate for the year. Translation adjustments are reported in other comprehensive income (loss) in the consolidated statements of comprehensive income (loss) and as cumulative translation adjustments in accumulated other comprehensive loss in the consolidated balance sheets.

Reverse Stock Split - All share numbers, including the number of shares underlying warrants, options, and convertible debt, and per share amounts presented in these 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 consolidated balance sheets and statement of cash flows have been reclassified to conform to the presentation of the current year 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 previously issued consolidated financial statements as of and for the year ended December 31, 2024 (refer to Note 24 for quarterly 2024 and 2025 impacts). 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 year ended December 31, 2024. This adjustment reflects the cumulative impact of previously

Table of Contents

unrecorded sales tax, interest, and penalties. The Company does not expect similar expense impacts to recur in future periods, as the underlying sales tax obligations have now been appropriately recognized and remediated.

Consolidated Financial Statements - Restatement Reconciliation Tables

In accordance with Accounting Standards Codification ("ASC") 250, Accounting Changes and Error Corrections, the Company has corrected this error by restating the prior period financial statements. The cumulative effect of the correction as of January 1, 2024, was a $1.4 million increase to accumulated deficit, as reflected in the consolidated statement of stockholders’ equity (deficit). The impact of the correction on the Company’s previously issued consolidated financial statements is summarized as follows:

A description of the restatement adjustments in the consolidated statement of comprehensive loss is as follows:

(i) The $1.6 million increase in general and administrative expenses is related to the adjustment for estimated state and local sales tax expense and for the related penalties on outstanding sales tax balances for the year ended December 31, 2024.

(ii) The $142 thousand increase in interest expense is related to the adjustment for estimated interest on outstanding state and local sales tax balances for the year ended December 31, 2024.

Consolidated Statements of Changes in Stockholders' Equity (Deficit):

The Consolidated Statement of Changes in Stockholders' Equity (Deficit) for 2024 in the accompanying consolidated financial statements has been restated to reflect the correction of prior period errors described above. The cumulative effect of errors originating in fiscal years prior to 2024 are presented as a discrete adjustment to the opening accumulated deficit balance as of January 1, 2024, rather than being allocated back to those individual years.

The line item "Correction of prior period error" presented in the Consolidated Statement of Changes in Stockholders' Equity (Deficit) represents the aggregate understatement of general and administrative expenses of $1.3 million and interest expense of $46 thousand originating in prior fiscal years, resulting in a cumulative increase to accumulated deficit of $1.4 million as of January 1, 2024 with no income tax effect due to the Company's full valuation allowance against its net deferred tax assets.

The accumulated deficit balance as of December 31, 2024, as restated, reflects both the cumulative opening adjustment of $1.4 million described above and the additional restatement adjustments of $1.7 million attributable to the understatement of general and administrative expenses and interest expense within fiscal year 2024. The combined effect of all restatement adjustments increased the Company's accumulated deficit by $3.1 million in the aggregate across all affected periods.

No other components of stockholders' equity (deficit), including common stock, additional paid-in capital, or other comprehensive income (loss), were affected by this restatement.

Accrued expenses and contract liabilities (i) 282 1,711 1,993

Net Cash Provided by Operating Activities $ 2,455 $ - $ 2,455

Description of the restatement adjustments in the consolidated statement of cash flows is as follows:

(i) The $1.7 million increase in accrued expenses for the year ended December 31, 2024 is related to the accrued sales tax, and the related interest and penalties on outstanding sales tax balances.

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

The significant accounting policies followed by the Company are summarized below:

Estimates - These 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 consolidated financial statements for any period necessarily involves the use of estimates and assumptions. Actual amounts may differ from these estimates. These 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, the estimated fair value of financial instruments, including warrants, and the accrual of state and local sales tax liabilities.

Cash and cash equivalents - Cash and cash equivalents consist of cash on hand and demand deposits. The demand deposits are highly liquid and readily convertible to known amounts of cash with insignificant risk of changes in value. They are considered to be cash equivalents as they have an original maturity of three months or less from the date of acquisition. The Company classifies all such highly liquid instruments that are not restricted as cash equivalents. Cash equivalents are stated at cost, which approximates fair value due to their short-term nature. For purposes of the statement of cash flows, the Company considers cash and cash equivalents to include cash on hand and demand deposits.

Accounts receivable - Accounts receivable are stated at the amount management expects to collect from outstanding balances. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that will not be fully collected. Management routinely assesses the financial strength of its customers and, consequently, believes accounts receivable are stated at the net realizable value and credit risk exposure is limited.

Allowance for credit losses - The Company maintains an allowance for credit losses to cover estimated losses on accounts receivable. The allowance is based on the Company's assessment of various factors, including historical loss experience, the age of receivables, current economic conditions, and the creditworthiness of customers. The allowance for credit losses is reviewed and adjusted as necessary at each reporting date.

Inventory - Inventory consists of purchased medical equipment and parts and is stated at the lower of first in, first out (“FIFO”) method, or net realizable value less allowance for selling and distribution expenses. The Company analyzes its inventory levels and for adjustments to inventory that has, or is expected to, become obsolete.

Property, plant, and equipment (PPE) - PPE is initially recorded at cost, which includes all expenditures directly attributable to bringing the asset into working condition for its intended use. Subsequent to initial recognition, PPE is carried at cost less accumulated depreciation and any impairment losses. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, with no residual value for most assets. The estimated useful lives and residual values of assets are reviewed periodically and adjusted if necessary. Major improvements and enhancements that extend the useful life of PPE are capitalized, while routine repairs and maintenance are expensed as incurred. Upon disposal or retirement of an asset, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is recognized in the period of disposal.

Goodwill - Goodwill represents the excess of the purchase price over the fair value of assets acquired and liabilities assumed. The Company accounts for goodwill under ASC Topic 350, Intangibles-Goodwill and Other. The Company tests goodwill for impairment annually, or more frequently whenever events or circumstances indicate impairment may exist. Goodwill is stated at cost less impairment losses. The Company completes its goodwill impairment test annually in the fourth quarter. The Company performed a qualitative evaluation at the reporting unit level and determined there was no goodwill impairment as of December 31, 2025, and 2024.

Intangible assets - Intangible assets arising from the Company’s acquisition are amortized on a straight‐line basis over the estimated useful life of each asset. Customer relationships have a useful life of seven years. Patents and tradenames have a useful life of nineteen years.

Impairment of long-lived assets - The Company annually reviews long-lived assets for impairment whenever facts and circumstances indicate that the carrying amounts of the assets may not be recoverable. An impairment loss is recognized only if the carrying amount of the asset is not recoverable and exceeds its fair value. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the asset’s carrying value is not recoverable, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds its fair value. The Company determines fair value by using a combination of comparable market values and discounted cash flows, as appropriate.

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 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.

Leases are classified as either operating or finance leases at the commencement date. The Company does not have any finance leases as of December 31, 2025. Operating lease ROU assets and liabilities are presented separately on the 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.

Fair value of financial instruments - The carrying values of accounts payable, and other short-term obligations approximate their fair values, because of the short-term maturities of these instruments.

The Company utilizes the guidance of ASC Topic 820-10, Fair Value Measurements (“ASC 820-10”), which defines fair value, establishes a framework for measuring fair value and requires disclosures about fair value measurements. The framework that is set forth in this standard is applicable to the fair value measurements where it is permitted or required under other accounting pronouncements.

The ASC 820-10 hierarchy ranks the quality and reliability of inputs, or assumptions, used in the determination of fair value and requires financial assets and liabilities carried at fair value to be classified and disclosed in one of the following three categories:

Level 1 – Observable inputs that reflect quoted prices (unadjusted) in active markets for identical assets and liabilities;

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and

Level 3 – Unobservable inputs that are not corroborated by market data, therefore requiring the Company to develop its own assumptions.

Convertible promissory notes – The Company evaluates its convertible instruments to determine if those contracts, or embedded components of those contracts, qualify as derivative financial instruments to be separately accounted for in accordance with ASC Topic 815, Derivatives and Hedging (“ASC 815”). The accounting treatment of derivative financial instruments requires that the Company record embedded conversion options and any related freestanding instruments at their fair values as of the inception date of the agreement and at fair value as of each subsequent balance sheet date. Any change in fair value is recorded as non-operating, non-cash income or expense for each reporting period at each balance sheet date. Conversion options are recorded as a discount to the host instrument and are amortized as amortization of debt discount on the consolidated statements of comprehensive loss over the life of the underlying instrument. The Company reassesses the classification of its derivative instruments at each balance sheet date. If the classification changes because of events during the period, the contract is reclassified as of the date of the event that caused the reclassification.

Debt discount – The Company records a debt discount related to warrants issued with debt at fair value and recognizes the cost using the straight-line method, which approximates the effective interest method, over the term of the related debt as interest expense, which is reported in the Other Income (Expense) section in our consolidated statements of comprehensive income (loss). This debt discount is reported as a reduction of the related debt liability.

Contract liabilities – The Company offers a separately priced extended warranty. Because the extended multi-year warranty represents a separate performance obligation, revenue is deferred as a contract liability and recognized over the time that the Company satisfies its performance obligations, which is the warranty term.

Estimated Sales Tax Liability - The Company is evaluating a state sales tax liability analysis for states in which it has economic nexus, and collecting exemption documentation from its customers. The Company will be subject to sales tax liabilities plus interest and penalties relating to historical activity in certain states. The estimated liability for sales tax plus interest and penalties is recorded in accrued expenses in the consolidated balance sheets. The liability may change from the original estimate recorded due to the Company remitting cash to the proper state tax authorities for historical sales tax and interest, inquiries from collecting jurisdictions, and settlement of outstanding amounts through programs offered through those jurisdictions. Due to the estimates involved in the analysis, the Company expects that the estimated liability will change in the future, and may exceed the current estimate. The Company also may be subject to examination by the relevant state tax authorities, which could affect the amount the Company ultimately pays under the accrual. The Company recognized sales tax not collected from its customers along with penalties as general and administrative expense on the consolidated statements of comprehensive income (loss). The Company recognized interest expense on past due amounts not remitted as interest expense on the consolidated statements of comprehensive income (loss).

Segment reporting - The Company operates as a single reporting entity and has determined that it has one reportable segment. This conclusion is based on the fact that the Company's chief operating decision maker (“CODM”), who is the Chief Executive Officer (“CEO”), reviews the financial information and makes decisions about resource allocation and performance assessment on a consolidated basis. The Company's operations are managed and evaluated as a single business unit, and the nature of the products and services, production processes, and customer base are similar across the entire organization.
