Risk factors and legal proceedings
The risks SANUWAVE Health, Inc. names in Item 1A of its 10-K filed Mar 26, 2026: 31 risks under these headings, as written.3
- 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.
- Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.
- 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.
- 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.
- 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.
- Changes in reimbursement affecting the wound care market could adversely affect our customers and indirectly reduce demand for our products.
- 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.
- The loss of our key management would likely hinder our ability to execute our business plan.
- We face an inherent risk of liability if the use or misuse of our products results in personal injury or death.
- We are dependent on information technology and our systems and infrastructure face certain risks, including from cybersecurity breaches and data leakage.
- If we are unable to expand, manage and maintain our direct sales and marketing organizations, we may not be able to generate anticipated revenue.
The other 20 risks
- If we fail to properly manage our growth effectively, our business could suffer.
- 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.
- Provisions in our Articles of Incorporation, Bylaws and Nevada law might decrease the chances of an acquisition.
- Regulatory Risks
- We are subject to extensive governmental regulation, including the FDA.
- Regulatory approval of our products may be withdrawn at any time.
- 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.
- Failure to obtain regulatory approval in foreign jurisdictions will prevent us from marketing our products abroad.
- Uncertainty surrounding and future changes to healthcare law in the United States may have a material adverse effect on us.
- 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.
- Failure to comply with the HIPAA and state-specific privacy laws, as such rules become applicable to our business, may increase our operational costs.
- 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.
- 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 use of hazardous materials in our operations may subject us to environmental claims or liability.
- 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.
- 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.
- Our patents may not be valid or enforceable and may be challenged by third parties.
- Issued patents and patent licenses may not provide us with any competitive advantage or provide meaningful protection against competitors.
- The ability to market the products we develop is subject to the intellectual property rights of third parties.
- Risks Related to our Common Stock
- Our stock price is volatile.
- We have not paid dividends in the past and do not expect to pay dividends in the future. Any return on investment may be limited to the value of our common stock.
Legal proceedings
In the ordinary course of business, the Company from time to time becomes involved in various legal proceedings involving a variety of matters. We do not believe there are any pending legal proceedings that will have a material adverse effect on our business, consolidated financial position, results of operations, or cash flows. However, the outcome of such legal matters is inherently unpredictable and subject to significant uncertainties. The Company expenses legal fees in the period in which they are incurred.
There are no material proceedings known to us to be contemplated by any governmental authority.
There are no material proceedings known to us, pending, or contemplated, in which any of our directors, officers or affiliates or any of our principal security holders, or any associate of any of the foregoing, is a party or has an interest adverse to us.
