BUSINESS Overview The Company is an ultrasound and shock wave technology company using patented systems of noninvasive, high-energy, acoustic shock waves or low intensity and non-contact ultrasound for regenerative medicine and other applications. Our focus is regenerative medicine utilizing noninvasive, acoustic shock waves or ultrasound to produce a biological response resulting in the body healing itself through the repair and regeneration of tissue, musculoskeletal, and vascular structures. Our two primary systems are UltraMIST ® and PACE ® . UltraMIST and PACE are the only two Food and Drug Administration (FDA) approved directed energy systems for wound healing. The UltraMIST system provides, through a fluid mist, low-frequency, non-contact, and pain free ultrasound energy deep inside the wound bed that promotes healing from within. The ultrasound acoustic waves promote healing by reducing inflammation and bacteria in the wound bed, while also increasing the growth of new blood vessels to the area. The UltraMIST system treatment must be administered by a healthcare professional. This proprietary technology has been cleared by the FDA for the promotion of wound healing through wound cleansing and maintenance debridement combined with ultrasound energy deposited inside the wound that stimulated tissue regeneration. The UltraMIST System is cleared for marketing in the U.S. by the FDA (K140782) but is not approved/cleared/licensed in any other jurisdiction. The PACE systems use acoustic pressure shockwaves generated by the Company’s Pulsed Acoustic Cellular Expression (PACE) technology to converge at precise selected targets to produce an extremely short duration compression burst. The precise targeting of tissue with PACE ® technology provides healthcare professionals with a tool to positively influence cellular form and function, which can result in pain relief, improved circulation, and tissue regeneration. The PACE ® system treatment must be administered by a healthcare professional. The PACE® line of products is marketed in various jurisdictions: • The dermaPACE® System was determined to be a Class II device by the FDA under the generic name extracorporeal shock wave device for treatment of chronic wounds per De Novo filing/order DEN160037. As a result of this order, we were immediately able to market dermaPACE as described in the De Novo request subject to the general control provisions of the Federal Food, Drug, and Cosmetic Act and the special controls identified in the order. Besides having permission to market in the U.S., dermaPACE is licensed for distribution and sale in the following jurisdictions: the European Union (CE Mark), Canada, Brazil, Egypt, Singapore and the United Arab Emirates. • Profile by SANUWAVE System is marketed only within the U.S. and is listed as a Class I device with the FDA (listing number D065463). Profile by SANUWAVE System is not approved/cleared/licensed in any other jurisdiction. • The orthoPACE® System is not marketed in the U.S. It is marketed in the European Union (CE Mark) and licensed for sale/distribution in South Korea and Taiwan. Our portfolio of wound treatment solutions provides patients with noninvasive technology that boosts the body’s normal healing and tissue regeneration processes. The Company is marketing its UltraMIST and PACE systems for usage primarily in the United States . Regarding the non-contact and non-thermal low frequency ultrasound UltraMIST system, the Company is focused on the following: • Growth and expansion of sales across the United States • Improvement of the functionality and ease-of-use for both medical personnel and patients • Identifying and qualifying antibacterial and anti-biofilm solutions to replace the saline solution used to produce the mist used by this system to conduct the ultrasound toward its target, which, the Company believes would make the system more effective in treating bacterial infections associated with skin conditions • The design of new applicators capable of treating large skin conditions, for improved efficiency in such cases. The Company is focused on further developing our PACE proprietary technology to activate healing in: • Acute and chronic wound conditions, including diabetic foot ulcers, venous and arterial ulcers, pressure sores, burns and other skin eruption conditions ; • Orthopedic applications, such as eliminating chronic pain in joints from trauma, arthritis or tendons/ligaments inflammation or tendinopathies, speeding the healing of fractures (including nonunion or delayed-union conditions), improving bone density in osteoporosis, fusing bones in the extremities and spine, and other potential sports injury applications; • Plastic/cosmetic applications such as cellulite smoothing, graft and transplant acceptance, skin tightening, scarring and other potential aesthetic uses; and • Cardiovascular applications for removing plaque due to atherosclerosis, eliminating occlusions and blood clots, and improving heart muscle and cardiac valves performance. 4 Table of Contents Merger Agreement with SEPA On August 23, 2023, we entered into an Agreement and Plan of Merger (the “ Merger Agreement ”) by and among SEP Acquisition Corp., a Delaware corporation (“ SEPA ”), SEP Acquisition Holdings Inc., a Nevada corporation, and a wholly owned subsidiary of SEPA (“ Merger Sub ”). Pursuant to the terms of the Merger Agreement, a business combination between the Company and SEPA (the “ Merger ”) will be affected. More specifically, and as described in greater detail below, at the effective time of the Merger (the “ Effective Time ”): • Merger Sub will merge with and into the Company, with the Company being the surviving company following the merger. • Each issued and outstanding share of the Company common stock will automatically be converted into Class A common stock of SEPA, par value $0.0001 per share, at the Conversion Ratio (as defined in the Merger Agreement); and • Outstanding Company convertible securities of the Company will be assumed by SEPA and will be converted into the right to receive Class A Common Stock of SEPA. Pursuant to the terms of the Merger Agreement, the holders of (i) Company common stock, (ii) in the money options to purchase Company common stock, (iii) in the money warrants to purchase Company common stock, and (iv) convertible promissory notes, collectively will be entitled to receive 7,793,000 shares of Class A Common Stock of SEPA. Out-of-the-money options and out-of-the-money warrants will be assumed by SEPA and converted into options or warrants, respectively, exercisable for shares of Class A Common Stock based on the Conversion Ratio; however, such out-of-the-money options and out-of-the-money warrants shall not be reserved for issuance from the Merger Consideration. The Merger Agreement contains certain conditions to Closing, including the following: • holders of 80% or more of the Company’s convertible notes with a maturity date occurring after the date of the Closing (the “ Closing Date ”), measured by number of shares of our common stock into which such convertible notes may be converted, agreeing to convert their convertible notes into shares of common stock immediately prior to the Effective Time. • holders of 80% or more of the Company’s warrants that would be outstanding on the Closing Date, measured by number of shares of our common stock subject to all such warrants in the aggregate, agreeing to convert their warrants into shares of common stock immediately prior to the Effective Time. • SEPA having at the Closing, at least $12,000,000 in cash and cash equivalents, including funds remaining in the trust account (after giving effect to the completion and payment of any redemptions) and the proceeds of any private placement in SEPA. As of the date of this Annual Report on Form 10-K, the holders of approximately 95% of our outstanding warrants covered by the preceding covenant and 100% of our outstanding convertible notes covered by the preceding covenant have committed to exchange such warrants and convertible notes for an aggregate of 1,217,222,186 shares and 219,841,980 shares, respectively, of our common stock immediately prior to the Closing. On February 21, 2024, we held a special meeting of holders of the Company’s common stock where the Merger Agreement and the transactions contemplated thereby (the “Business Combination”) was approved by a majority vote. In February 2024, the Company amended the Merger Agreement to extend the date after which the Company or SEPA, in its discretion, can elect to terminate the Merger Agreement if any of the conditions to closing of the other party have not been met or waived, from February 28, 2024 to April 30, 2024. UltraMIST - Ultrasound Healing Therapy UltraMIST is an FDA approved powerful, non-contact, non-thermal ultrasound therapy system used to promote healing in a wide range of wound types. The system never touches the wound surface making it pain free. UltraMIST promotes wound healing below the skin surface by modulating cell membranes to drive increased blood flow and capillary formation. It also reduces and removes a wide range of bacteria, including biofilms, while preserving healthy structures. UltraMIST is FDA approved to treat malaises such as diabetic foot ulcers, pressure ulcers, venous leg ulcers, deep tissue pressure injuries, and surgical wounds. PACE Technology for Regenerative Medicine Our PACE system candidates, including our dermaPACE System, deliver high-energy acoustic pressure shockwaves to produce compressive and tensile stresses on cells and tissue structures. These mechanical stresses at the cellular level have been shown in pre-clinical work to promote angiogenic and positive modulated inflammatory responses, and quickly initiate the healing cascade. This has been shown in pre-clinical work to result in microcirculatory improvement, including increased perfusion and blood vessel widening, the production of angiogenic growth factors, enhanced new blood vessel formation (angiogenesis) and the subsequent regeneration of tissue such as skin, musculoskeletal and vascular structures. PACE procedures trigger the initiation of an accelerated and modulated inflammatory response that speeds wounds into proliferation phases of healing and subsequently returns a chronic condition to an acute condition to help reinitiate the body’s own healing response. The Company believes our PACE technology is well suited for various applications due to its activation of a broad spectrum of cellular events critical for the initiation and progression of healing. 5 Table of Contents dermaPACE The Company is focused on the development of products that treat unmet medical needs in large market opportunities. Our FDA approval in the United States for our, dermaPACE system is the first step in providing an option to a currently unmet need in the treatment of diabetic foot ulcers. Diabetes is common, disabling, and deadly. In the United States, diabetes has reached epidemic proportions. Based on our research, foot ulcerations are one of the leading causes of hospitalization in diabetic patients and lead to billions of dollars in health care expenditures annually. dermaPACE is noninvasive and does not require anesthesia, making it a cost-effective, time-efficient, and painless approach to wound care. The dermaPACE’s noninvasive treatments are designed to produce the body’s own healing response and followed by simple standard of care dressing changes, are designed to allow for limited disruption to the patients’ normal lives and have no effect on mobility while their wounds heal. The dermaPACE has received the European CE Mark approval to treat acute and chronic defects of the skin and subcutaneous soft tissue, such as in the treatment of pressure ulcers, diabetic foot ulcers, burns, and traumatic and surgical wounds. The dermaPACE is also licensed for sale in Canada, Australia, New Zealand and South Korea. Additionally, our joint venture partner in Brazil, Diversa SA, received approval from the Brazilian Agência Nacional de Vigilância Sanitária (“National Health Surveillance Agency” or “ANVISA”) to market dermaPACE to treat diabetic foot ulcers in Brazil. Profile Additionally, the Company has developed and introduced Profile by SANUWAVE as an immediately available solution for pain management in sports medicine and physical therapy in the U.S. market. Profile by SANUWAVE is a therapeutic massager intended for the relief of minor muscle aches and pains via SANUWAVE’s Diffused Acoustic Pressure (DAP ® ) technology. DAP ® delivers the beneficial, therapeutic field of the acoustic pressure waves without the impact and potential pain of a focused pulse. There is a significant need in the U.S. for pain management products and the Company believes the non-invasive delivery of therapeutic shockwaves for its treatment can help to serve this market. Strategy Our strategy is focused on the commercialization of our patented, non-invasive, and biological response-activating medical systems for the repair and regeneration of skin, musculoskeletal tissue, and vascular structures. Our wound care portfolio of regenerative medicine products help restore the body's normal healing processes, by activating biologic signaling and angiogenic responses. The key elements of our strategy include the following: • Commercialize and support the domestic distribution of our UltraMIST and PACE systems to treat wounds; • Reduce and normalize operating costs to support growth; • Develop and commercialize our noninvasive biological response activating devices in the regenerative medicine area for the treatment of skin, musculoskeletal tissue, and vascular structures. Scientific Advisors The Company has established a network of scientific advisors that brings expertise in wound healing, orthopedics, cosmetics, clinical and scientific research, and FDA experience.

Intellectual Property Our success depends in part on our ability to obtain and maintain proprietary protection for our products, technology, and know-how, to operate without infringing on the proprietary rights of others and to prevent others from infringing upon our proprietary rights. The Company seeks to protect our proprietary position by, among other methods, filing United States and selected foreign patent applications and United States and selected foreign trademark applications related to our proprietary technology, inventions, products, and improvements that are important to the development of our business. Effective trademark, service mark, copyright, patent, and trade secret protection may not be available in every country in which our products are made available. The protection of our intellectual property may require the expenditure of significant financial and managerial resources. Patents The Company considers the protection afforded by patents important to our business. The Company intends to seek and maintain patent protection in the United States and select foreign countries, where deemed appropriate for products that the Company develops. In general, our patents are effective, ranging from 6 months to 16 years. There are no assurances that any patents will result from our patent applications, or that any patents that may be issued will protect our intellectual property, or that any issued patents or pending applications will not be successfully challenged, including as to ownership and/or validity, by third parties. In addition, if the Company does not avoid infringement of the intellectual property rights of others, the Company may have to seek a license to sell our products, defend an infringement action or challenge the validity of intellectual property in court. Any current or future challenges to our patent rights, or challenges by us to the patent rights of others, could be expensive and time consuming. The Company believes that our owned and licensed patent rights provide a competitive advantage with respect to others that might seek to utilize certain of our apparatuses and methods incorporating extracorporeal acoustic pressure shockwave technologies that the Company has patented. However, the Company does not hold patent rights that cover all of our products, product components, or methods that utilize our products. The Company also has not conducted a competitive analysis or valuation with respect to our issued and pending patent portfolio in relation to our current products and/or competitor products. In August 2005, we entered into a license agreement with HealthTronics Inc. (“HealthTronics”) in connection with our acquisition of certain assets and intellectual property relating to orthopedic, tendinopathy, skin wounds, cardiac, dental, neural medical conditions and to all conditions in animals (the “Ortho Field”) from HealthTronics. The majority of the intellectual property licensed from HealthTronics was associated with the construction of shockwave devices, indications for orthopedic treatments, and wound care. These patents and patent applications have either expired or were not pursued in our portfolio. Under our license to HealthTronics, Inc., we reserved exclusive rights in our purchased portfolio as to the Ortho Field. HealthTronics received field-exclusive and sublicensable rights under the purchased portfolio as to (1) certain HealthTronics lithotripsy devices in all fields other than the Ortho Field, and (2) all products in the treatment of renal, ureteral, gall stones and other urological conditions (the “Litho Field”). HealthTronics also received non-exclusive and non-sublicensable rights in the purchased portfolio as to any products in all fields other than the Ortho Field and Litho Field. 7 Table of Contents Pursuant to mutual amendment and other assignment-back rights under the patent license agreement with HealthTronics, we are also a licensee of certain patents and patent applications that have been assigned to HealthTronics. We received a perpetual, non-exclusive and royalty-free license to nine issued foreign patents. Our non-exclusive license is subject to HealthTronics’ sole discretion to further maintain any of the patents and pending applications assigned back to HealthTronics. In August 2020, we entered into an asset purchase agreement with Celularity Inc. (“Celularity”), pursuant to which we acquired all of Celularity’s assets related to the MIST Therapy System and UltraMIST System, including all intellectual property and trademarks related to MIST and UltraMIST. These assets are for use in low frequency and non-contact ultrasound to treat wounds.

The Company has the following trademark registrations: SANUWAVE ® (United States, European Community, Canada, Japan, Switzerland, United Kingdom, Taiwan and under the Madrid Protocol), dermaPACE ® (United States, European Community, Japan, South Korea, Switzerland, Taiwan, Canada, China, Brazil, Mexico, and under the Madrid Protocol), angioPACE ® (European Community and United Kingdom), PACE ® - Pulsed Acoustic Cellular Expression (United States, European Community, China, Hong Kong, Singapore, Switzerland, Taiwan, and Canada), orthoPACE ® (United States, United Kingdom, and European Community), DAP ® - Diffused Acoustic Pressure (United States and European Community), Profile ® (United States, European Community, and United Kingdom) Energy First ® (United States), Healing Today, Curing Tomorrow ® (United States), and UltraMIST ® (United States). 10 Table of Contents Through the acquisition of UltraMIST®/MIST assets from Celularity Inc., the Company is the owner of the Celleration ® (United States, Australia, Europe Community, and Japan), Proven Healing ® (Madrid Protocol, European Community, and United Kingdom), MIST Ultrasound Healing Therapy & Design ® (United States), MIST ® (United States), MIST Therapy ® (United States), and MIST & Design ® (United States) registered trademarks. The Company also maintains trademark registrations for: OssaTron ® (United States), OSWT ® (Switzerland) Evotron ® (United States, Germany and Switzerland), Evotrode ® (United States, Germany and Switzerland), Orthotripsy ® (United States). The Company phased out the OssaTrode ® (United States, Germany and Switzerland), Equitron ® (United States and Switzerland). Reflectron ® (Germany and Switzerland) and Reflectrode ® (Germany and Switzerland), evoPACE ® (Canada, Australia, European Community and Switzerland) trademarks, due to the fact that OssaTrode ® , Equitron ® , Reflectron ® and Reflectrode ® products are no longer available for sale in any market and evoPACE ® is a product that was never commercialized. Competition The Company believes the advanced wound care market can benefit from our technology which up-regulates the biological factors that promote wound healing. Current medical technologies developed by Acelity L.P. Inc, (formerly Kinetic Concepts, Inc.) now owned by 3M, Organogenesis, Inc., Smith & Nephew plc, Derma Sciences, Inc., MiMedx Group, Inc., Osiris Therapeutics, Inc., Molnlycke Health Care, and Systagenix Wound Management (US), Inc. (now owned by Acelity) and Softwave Tissue Regeneration Technologies, manage wounds, but, in our opinion, do not provide the value proposition to the patients and care givers like our PACE technology has the potential to do. The leading medical device serving this market is the Vacuum Assisted Closure (“V.A.C.”) System marketed by KCI. The V.A.C. is a negative pressure wound therapy device that applies suction to debride and manage wounds. There are also several companies that market extracorporeal shockwave device products targeting lithotripsy and orthopedic markets, including Dornier MedTech, Storz Medical AG, Electro Medical Systems (EMS) S.A., Softwave Tissue Regneration Technologies, and CellSonic Medical which could ultimately pursue the wound care market. Nevertheless, the Company believes that the PACE systems have a competitive advantage over all of these existing technologies by achieving wound closure by means of a minimally invasive process through innate biological response to PACE technology. Regarding the companies that use low frequency ultrasound that creates a pressure wave producing micro-strains due to mechanical forces that deform cell membrane and therefore promote healing, there are technologies developed by Arobella Medical LLC, NanoVibronix, Chattanooga, and EDAP TMS to manage wound care. However, these treatment devices or medical systems are different in design and mode of application of the ultrasound when compared to SANUWAVE’s UltraMIST. The Company believes that UltraMIST has a competitive advantage over all of these existing technologies, due to broad medical indications, simplicity of use, wound healing results and the tolerability of the treatment by the patients, especially for painful wounds. Developing and commercializing new products is highly competitive. The market is characterized by extensive research and clinical efforts and rapid technological change. The Company faces intense competition worldwide from medical device, biomedical technology and medical products and combination products companies, including major pharmaceutical companies. The Company may be unable to respond to technological advances through the development and introduction of new products. Most of our existing and potential competitors have substantially greater financial, marketing, sales, distribution, manufacturing and technological resources. These competitors may also be in the process of seeking FDA or other regulatory approvals, or patent protection, for new products. Our competitors may commercialize new products in advance of our products. Our products also face competition from numerous existing products and procedures, which currently are considered part of the standard of care. To compete effectively, our products will have to achieve widespread market acceptance. Regulatory Matters FDA Regulation Each of our products must be approved or cleared by the FDA before it is marketed in the United States. Before and after approval or clearance in the United States, our products are subject to extensive regulation by the FDA under the Federal Food, Drug, and Cosmetic Act and/or the Public Health Service Act, as well as by other regulatory bodies. FDA regulations govern, among other things, the development, testing, manufacturing, labeling, safety, storage, record-keeping, market clearance or approval, advertising and promotion, import and export, marketing and sales, and distribution of medical devices and pharmaceutical products. 11 Table of Contents In the United States, the FDA subjects medical products to rigorous review. If the Company does not comply with applicable requirements, the Company may be fined, the government may refuse to approve our marketing applications or to allow us to manufacture or market our products, and the Company may be criminally prosecuted. Failure to comply with the law could result in, among other things, warning letters, civil penalties, delays in approving or refusal to approve a product candidate, product recall, product seizure, interruption of production, operating restrictions, suspension or withdrawal of product approval, injunctions, or criminal prosecution. The FDA has determined that our technology and products constitute “medical devices.” The FDA determines what center or centers within the FDA will review the product and its indication for use and determines under what legal authority the product will be reviewed. For the current indications, our products are being reviewed by the Center for Devices and Radiological Health. However, the Company cannot be sure that the FDA will not select a different center and/or legal authority for one or more of our other product candidates, in which case the governmental review requirements could vary in some respects. FDA Approval or Clearance of Medical Devices In the United States, medical devices are subject to varying degrees of regulatory control and are classified in one of three classes depending on the extent of controls the FDA determines are necessary to reasonably ensure their safety and efficacy: • Class I: general controls, such as labeling and adherence to quality system regulations; • Class II: special controls, pre-market notification (510(k)), specific controls such as performance standards, patient registries, and post market surveillance, and additional controls such as labeling and adherence to quality system regulations; and • Class III: special controls and approval of a pre-market approval (PMA) application. Each of our products require FDA authorization prior to marketing, by means of either a 510(k) clearance or a PMA approval. To request marketing authorization by means of a 510(k) clearance, the Company must submit a pre-market notification demonstrating that the proposed device is substantially equivalent to another legally marketed medical device, has the same intended use, and is as safe and effective as a legally marketed device and does not raise different questions of safety and effectiveness than does a legally marketed device. 510(k) submissions generally include, among other things, a description of the device and its manufacturing, device labeling, medical devices to which the device is substantially equivalent, safety and biocompatibility information, and the results of performance testing. In some cases, a 510(k) submission must include data from human clinical studies. Marketing may commence only when the FDA issues a clearance letter finding substantial equivalence. After a device receives 510(k) clearance, any product modification that could significantly affect the safety or effectiveness of the product, or that would constitute a significant change in intended use, requires a new 510(k) clearance or, if the device would no longer be substantially equivalent, would require a PMA. If the FDA determines that the product does not qualify for 510(k) clearance, then a company must submit, and the FDA must approve, a PMA before marketing can begin. A PMA application must provide a demonstration of safety and effectiveness, which generally requires extensive pre-clinical and clinical trial data. Information about the device and its components, device design, manufacturing, and labeling, among other information, must also be included in the PMA. As part of the PMA review, the FDA will inspect the manufacturer’s facilities for compliance with quality system regulation requirements, which govern testing, control, documentation, and other aspects of quality assurance with respect to manufacturing. The PMA approval can include post-approval conditions, including, among other things, restrictions on labeling, promotion, sale and distribution, or requirements to do additional clinical studies post-approval. Even after approval of a PMA, a new PMA or PMA supplement is required to authorize certain modifications to the device, its labeling, or its manufacturing process. Supplements to a PMA often require the submission of the same type of information required for an original PMA, except that the supplement is generally limited to that information needed to support the proposed change from the product covered by the original PMA. Obtaining medical device clearance, approval, or licensing in the United States or abroad can be an expensive process. International fee structures vary from minimal to substantial, depending on the country. In addition, the Company is subject to annual establishment registration fees in the United States and abroad. Device licenses require periodic renewal with associated fees as well. In the United States, there is an annual requirement for submitting device reports for Class III/PMA devices, along with an associated fee. Currently, the Company is registered as a Small Business Manufacturer with the FDA and as such are subject to reduced fees. If, in the future, our revenues exceed a certain annual threshold limit, the Company may not qualify for the Small Business Manufacturer reduced fee amounts and will be required to pay full fee amounts. Post-Approval Regulation of Medical Devices After a device is cleared or approved for marketing, numerous and pervasive regulatory requirements continue to apply. These include: • the FDA quality systems regulation, which governs, among other things, how manufacturers design, test, manufacture, exercise quality control over, and document manufacturing of their products; 12 Table of Contents • labeling and claims regulations, which prohibit the promotion of products for unapproved or “off-label” uses and impose other restrictions on labeling; • the Medical Device Reporting regulation, which requires reporting to the FDA of certain adverse experiences associated with use of the product; and • post market surveillance, including documentation of clinical experience and follow-on, confirmatory studies. The Company continues to be subject to inspection by the FDA to determine our compliance with regulatory requirements, as are our suppliers, contract manufacturers, and contract testing laboratories. International sales of medical devices manufactured in the United States that are not approved or cleared by the FDA are subject to FDA export requirements. Exported devices are subject to the regulatory requirements of each country to which the device is exported. Exported devices may also fall under the jurisdiction of the United States Department of Commerce/Bureau of Industry and Security and compliance with export regulations may be required for certain countries. Manufacturing Certifications The Medical Device Single Audit Program (MDSAP) – allows a single regulatory audit of a medical device manufacturer’s quality management system to satisfy the requirements of multiple regulatory authorities (RAs). Five RAs: The Australian Therapeutic Goods Administration (TGA), Brazil’s Agência Nacional de Vigilância Sanitária (ANVISA), Health Canada, MHLW/PMDA (Japan), and the FDA participated in a three-year MDSAP Pilot which concluded in December 2016. These RAs will continue to participate in MDSAP as the program moved into its operational phase starting January 2017, with Health Canada making a full transition from the Canadian Medical Devices Conformity Assessment System (CMDCAS) to MDSAP. MDSAP uses recognized third-party auditors – auditing organizations (AOs) – to conduct a single quality management system audit that satisfies the requirements of multiple regulatory authorities. Manufacturers only needed to comply with the regulations from the jurisdictions where they sell their products. The MDSAP certificate indicates that a manufacturer complies with the regulatory requirements for the markets defined in the certificate. The certificate does not represent marketing authorization, nor does it require any regulatory authority to issue a marketing authorization or endorsement to the device manufacturer. The Company has been certified to the MDSAP requirements for all five participating countries, most recently successfully completing a MDSAP recertification audit in September 2022. This certificate is valid for three years. Annual surveillance audits are required to maintain this certification. Manufacturing cGMP Requirements Manufacturers of medical devices are required to comply with FDA manufacturing requirements contained in the FDA’s current Good Manufacturing Practices (cGMP) set forth in the quality system regulations promulgated under section 520 of the Federal Food, Drug and Cosmetic Act. cGMP regulations require, among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation. The manufacturing facility for our products must meet cGMP requirements to the satisfaction of the FDA pursuant to a pre-PMA approval inspection before the Company can use it. The Company and some of our third-party service providers are also subject to periodic inspections of facilities by the FDA and other authorities, including procedures and operations used in the testing and manufacture of our products to assess our compliance with applicable regulations. Failure to comply with statutory and regulatory requirements subjects a manufacturer to possible legal or regulatory action, including the seizure or recall of products, injunctions, consent decrees placing significant restrictions on or suspending manufacturing operations, and civil and criminal penalties. Adverse experiences with the product must be reported to the FDA and could result in the imposition of marketing restrictions through labeling changes or in product withdrawal. Product approvals may be withdrawn if compliance with regulatory requirements is not maintained or if problems concerning safety or efficacy of the product occur following the approval. International Regulation We are subject to regulations and product registration requirements in many foreign countries in which we may sell our products, including in the areas of product standards, packaging requirements, labeling requirements, import and export restrictions and tariff regulations, duties and tax requirements. The time required to obtain clearance required by foreign countries may be longer or shorter than that required for FDA clearance, and requirements for licensing a product in a foreign country may differ significantly from FDA requirements. 13 Table of Contents United States Anti-Kickback and False Claims Laws In the United States, there are Federal and state anti-kickback laws that prohibit the payment or receipt of kickbacks, bribes or other remuneration intended to induce the purchase or recommendation of healthcare products and services. Violations of these laws can lead to civil and criminal penalties, including exclusion from participation in Federal healthcare programs. These laws are potentially applicable to manufacturers of products regulated by the FDA as medical devices, such as us, and hospitals, physicians, and other potential purchasers of such products. Other provisions of Federal and state laws provide civil and criminal penalties for presenting, or causing to be presented, to third-party payers for reimbursement, claims that are false or fraudulent, or which are for items or services that were not provided as claimed. In addition, certain states have implemented regulations requiring medical device and pharmaceutical companies to report all gifts and payments over $50 to medical practitioners. This does not apply to instances involving clinical trials. Although we intend to structure our future business relationships with clinical investigators and purchasers of our products to comply with these and other applicable laws, it is possible that some of our business practices in the future could be subject to scrutiny and challenge by Federal or state enforcement officials under these laws. Third Party Reimbursement We anticipate that sales volumes and prices of the products we commercialize will depend in large part on the availability of coverage and reimbursement from third party payers. Third party payers include governmental programs such as Medicare and Medicaid, private insurance plans, and workers’ compensation plans. Even though a new product may have been approved or cleared by the FDA for commercial distribution, we may find limited demand for the device until adequate history of reimbursement has been obtained from governmental and private third-party payers. The CPT code for UltraMIST is 97610. This Category 1 code describes a system used in wound care that uses low frequency ultrasonic energy to atomize a liquid and deliver continuous low frequency ultrasound to the wound bed. The CPT codes for the dermaPACE System using extracorporeal shock wave technology to treat diabetic foot ulcers are 0512T and 0513T. The codes 0512T and 0513T are for extracorporeal shock wave for integumentary wound healing, including topical application and dressing and high energy extracorporeal shockwave therapy for integumentary wound healing. While these are Category 3 codes because the dermaPACE System is considered experimental by the Centers for Medicare & Medicaid Services, this designation does not preclude billing and obtaining payment. Instead, claims are reviewed on an individual basis. In international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific product lines and procedures. There can be no assurance that procedures using our products will be considered medically reasonable and necessary for a specific indication, that our products will be considered cost-effective by third party payers, that an adequate level of reimbursement will be available or that the third-party payers’ reimbursement policies will not adversely affect our ability to sell our products profitably. We believe that the overall escalating costs of medical products and services has led to, and will continue to lead to, increased pressures on the healthcare industry to reduce the costs of products and services. In addition, recent healthcare reform measures, as well as legislative and regulatory initiatives at the Federal and state levels, create significant additional uncertainties. There can be no assurance that third party coverage and reimbursement will be available or adequate, or that future legislation, regulation, or reimbursement policies of third-party payers will not adversely affect the demand for our products or our ability to sell these products on a profitable basis. The unavailability or inadequacy of third-party payer coverage or reimbursement would have a material adverse effect on our business, operating results and financial condition. Confidentiality and Security of Personal Health Information The Health Insurance Portability and Accountability Act of 1996, as amended (HIPAA), contains provisions that protect individually identifiable health information from unauthorized use or disclosure by covered entities and their business associates. The Office for Civil Rights of the U.S. Department of Health and Human Services (HHS), the agency responsible for enforcing HIPAA, has published regulations to address the privacy (the “Privacy Rule”) and security (the “Security Rule”) of protected health information (PHI). HIPAA also requires that all providers who transmit claims for health care goods or services electronically utilize standard transaction and data sets and to standardize national provider identification codes. In addition, the American Recovery and Reinvestment Act enacted the HITECH Act, which extends the scope of HIPAA to permit enforcement against business associates for a violation, establishes new requirements to notify the Office for Civil Rights of HHS of a breach of HIPAA, and allows the Attorneys General of the states to bring actions to enforce violations of HIPAA. We anticipate that, as we expand our PACE business, we may in the future be a covered entity under HIPAA. We have adopted policies and procedures to comply with the Privacy Rule, the Security Rule and the HIPAA statute as such regulations become applicable to our business. We currently don’t capture patient data through our PACE system. 14 Table of Contents In addition to the HIPAA Privacy Rule and Security Rule described above, we may become subject to state laws regarding the handling and disclosure of patient records and patient health information. These laws vary widely. Penalties for violation include sanctions against a laboratory’s licensure as well as civil or criminal penalties. Additionally, private individuals may have a right of action against us for a violation of a state’s privacy laws. We intend to adopt policies and procedures to ensure material compliance with state laws regarding the confidentiality of health information as such laws become applicable to us and to monitor and comply with new or changing state laws on an ongoing basis. Environmental and Occupational Safety and Health Regulations Our operations are subject to extensive Federal, state, provincial and municipal environmental statutes, regulations and policies, including those promulgated by the Occupational Safety and Health Administration, the United States Environmental Protection Agency, Environment Canada, Alberta Environment, the Department of Health Services, and the Air Quality Management District, that govern activities and operations that may have adverse environmental effects such as discharges into air and water, as well as handling and disposal practices for solid and hazardous wastes. Some of these statutes and regulations impose strict liability for the costs of cleaning up, and for damages resulting from, sites of spills, disposals, or other releases of contaminants, hazardous substances and other materials and for the investigation and remediation of environmental contamination at properties leased or operated by us and at off-site locations where we have arranged for the disposal of hazardous substances. In addition, we may be subject to claims and lawsuits brought by private parties seeking damages and other remedies with respect to similar matters. We have not to date needed to make material expenditures to comply with current environmental statutes, regulations and policies. However, we cannot predict the impact and costs those possible future statutes, regulations and policies will have on our business. Employees As of December 31, 2023, we had a total of 31 full time employees in the United States. Of these, five were engaged in research and development which includes clinical, regulatory, and quality. None of our employees are represented by a labor union or covered by a collective bargaining agreement. We believe our relationship with our employees is good. Corporate Information We were formed as a Nevada corporation in 2004. Our corporate headquarters address 11495 Valleyview Road, Eden Prairie, MN 55344, and our main telephone number is (800) 545-8810 or (952) 656-1029. Available Information We maintain a website at www.sanuwave.com . We make available on our website, free of charge, our periodic reports and registration statements filed with the SEC, including our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Sections 13(a) and 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We make these reports available through our website as soon as reasonably practicable after we electronically file such reports with, or furnish such reports to the SEC. Our internet site and the information contained on or connected to that site are not incorporated by reference into this Annual Report on Form 10-K. The SEC also maintains a website at www.sec.gov that contains reports, proxy statements and other information regarding issuers that file electronically with the SEC. 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 the Business Combination The Business Combination is subject to conditions, including certain conditions that may not be satisfied on a timely basis, if at all. Unless waived by the parties to the Merger Agreement, and subject to applicable law, the consummation of the Business Combination is subject to several conditions set forth in the Merger Agreement. For more information about conditions for the consummation of the Business Combination, see Part II Item 5 – Management’s Discussion and Analysis of Financial Condition and Results of Operations. 15 Table of Contents The Merger Agreement includes a Minimum Cash Condition as a condition to the consummation of the Merger, which may make it more difficult for SEP Acquisition Corp.(“SEPA”) and the Company to complete the Business Combination as contemplated. The Merger Agreement provides that the Company’s obligation to consummate the Business Combination is conditioned on, among other things, that as of the Closing, SEPA has at least $12,000,000 (“Minimum Cash Condition Amount”) resulting from (i) proceeds that have not been redeemed in the Redemption and (ii) proceeds of the private placement in SEPA (the “PIPE Investment"). Because SEPA Stockholders elected to redeem 495,067 shares of Class A Common Stock, in connection with the Business Combination, then SEPA will need to obtain PIPE Investment in order to satisfy the Minimum Cash Condition. As of the date of this filing, no commitments have been given for the proposed financing from the PIPE Investment, and there is no assurance that SEPA will enter into subscriptions for the PIPE Investment. The actual amount that SEPA raises in the PIPE Investment, if any, will depend on market conditions and other factors. This condition is for the sole benefit of the Company. If such condition is not met, and such condition is not or cannot be waived under the terms of the Merger Agreement, then the Merger Agreement could terminate, and the proposed Business Combination may not be consummated. If such condition is waived and the Business Combination is consummated with less than the Minimum Cash Condition Amount in the Trust Account, the cash held by the Combined Company (including the Company) in the aggregate, after the Closing may not be sufficient to allow the Combined Company to operate and pay Combined Company bills as they become due. Any such event in the future may negatively impact the analysis regarding the Combined Company’s ability to continue as a going concern at such time. There can be no assurance that the shares of the Combined Company’s Class A Common Stock that will be issued in connection with the Business Combination will be approved for listing on Nasdaq, or another U.S national exchange, following the Closing, or that the Combined Company will be able to comply with the continued listing rules of Nasdaq, or another U.S. national exchange. In connection with the Business Combination and as a condition to the Company’s obligations to complete the Business Combination, the Combined Company will be required to demonstrate compliance with Nasdaq’s initial listing requirements. The Company and SEPA cannot assure you that the Combined Company will be able to meet those initial listing requirements or qualify to list on another national securities exchange. Even if the Combined Company’s Class A Common Stock is approved for listing on Nasdaq, the Combined Company may not meet the Nasdaq continued listing requirements following the Business Combination. The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Because SEPA’s Units, Class A Common Stock, and warrants are listed on Nasdaq, SEPA’s Units, Class A Common Stock and warrants qualify as covered securities under the statute. Although the states are preempted from regulating the sale of SEPA’s securities, the federal statute does allow the states to investigate companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case. Certain state securities regulators view blank check companies unfavorably and might use these powers, or threaten to use these powers, to hinder the sale of securities of blank check companies in their states. Further, if SEPA was no longer listed on Nasdaq, SEPA’s securities would not qualify as covered securities under the statute and SEPA would be subject to regulation in each state in which SEPA offers its securities. The announcement of the proposed Business Combination could disrupt the Company’s relationships with its customers, suppliers, business partners and others, as well as its operating results and business generally. Whether or not the Business Combination and related transactions are ultimately consummated, as a result of uncertainty related to the proposed transactions, risks relating to the impact of the announcement of the Business Combination on the Company’s business include the following: • its employees may experience uncertainty about their future roles, which might adversely affect the Combined Company’s ability to retain and hire key personnel and other employees; • customers, suppliers, business partners and other parties with which we maintain business relationships may experience uncertainty about its future and seek alternative relationships with third parties, seek to alter their business relationships with us or fail to extend an existing relationship with the Company; and • The Company has expended and will continue to expend significant costs, fees and expenses for professional services and transaction costs in connection with the proposed Business Combination. If any of the aforementioned risks were to materialize, they could lead to significant costs which may impact the Company and, in the future, the Combined Company’s results of operations and cash available to fund its business. 16 Table of Contents We will be subject to contractual restrictions while the Business Combination is pending. The Merger Agreement restricts the Company from making certain expenditures and taking other specified actions without the consent of SEPA until the Business Combination occurs. These restrictions may prevent the Company from pursuing attractive business opportunities that may arise prior to the completion of the Business Combination. The Company and SEPA will incur significant transaction and transition costs in connection with the Business Combination. The Company and SEPA have both incurred and expect to incur significant, non-recurring costs in connection with consummating the Business Combination and following the consummation of the Business Combination. The Company and SEPA may also incur additional costs to retain key employees. Certain transaction costs incurred in connection with the Merger Agreement (including the Business Combination), including all legal, accounting, consulting, investment banking and other fees, expenses, and costs, will be paid by the Combined Company following the Closing. If the Business Combination does not meet the expectations of investors or securities analysts, the market price of SEPA’s securities (prior to the Closing), or the market price of the Combined Company’s Class A Common Stock after the Closing, may decline. If the Business Combination does not meet the expectations of investors or securities analysts, the market price of SEPA’s securities prior to the Closing may decline. The market values of SEPA’s securities at the time of the Business Combination may vary significantly from their prices on the date the Merger Agreement was executed, or the date the Company’s Stockholders voted on the Business Combination. Because the number of shares to be issued pursuant to the Merger Agreement will not be adjusted to reflect any changes in the market price of SEPA’s Class A Common Stock, the market value of Class A Common Stock issued in connection with the Business Combination may be higher or lower than the values of these shares on earlier dates. In addition, following the Business Combination, fluctuations in the price of securities of the Combined Company could contribute to the loss of all or part of your investment. The valuation ascribed to the Company in the Business Combination may not be indicative of the price that will prevail in the trading market following the Business Combination. If an active market for SEPA’s securities develops and continues, the trading price of the securities of the Combined Company following the Business Combination could be volatile and subject to wide fluctuations in response to various factors, some of which are beyond the Combined Company’s control. Any of the factors listed below could have a material adverse effect on your investment in the Combined Company’s securities and the Combined Company’s securities may trade at prices significantly below the price you paid for them. In such circumstances, the trading price of the Combined Company’s securities may not recover and may experience a further decline. Factors affecting the trading price of the securities of the Combined Company after the Closing may include: • the Combined Company may be required to raise additional funds to finance operations and the Combined Company may not be able to do so, and/or the terms of any financings may not be advantageous to the Combined Company; • The Company has a history of losses, and the Combined Company may continue to incur losses and may not achieve or maintain profitability; • the medical device/therapeutic product industries are highly competitive and subject to rapid technological change, so if the Combined Company’s competitors are better able to develop and market products that are safer and more effective than any products the Combined Company may develop, the Combined Company’s commercial opportunities will be reduced or eliminated; • if the Combined Company’s products and product candidates do not gain market acceptance among physicians, patients and the medical community, the Combined Company may be unable to generate significant revenues, if any; • any product candidates of the Combined Company may not be developed or commercialized successfully; • the Combined Company may not successfully establish and maintain licensing and/or partnership arrangements for technology for non-medical uses, which could adversely affect the Combined Company’s ability to develop and commercialize non-medical technology; • The Company’s product component materials are only produced by a single supplier for such product component. If the Combined Company is unable to obtain product component materials and other products from our suppliers that the Combined Company will depend on for operations, or find suitable replacement suppliers, the Combined Company’s ability to deliver products to market will likely be impeded, which could have a material adverse effect on the Combined Company; • we currently sell products through distributors and partners whose sales account for the majority of revenues and accounts receivable. The Combined Company’s business and results of operations could be adversely affected by any business disruptions or credit, or other financial difficulties experienced by such distributors or partners; • the Combined Company faces an inherent risk of liability if the use or misuse of product candidates results in personal injury or death; 17 Table of Contents • actual or anticipated fluctuations in the Combined Company’s quarterly financial results or the quarterly financial results of companies perceived to be similar to the Combined Company may negatively impact the trading price of the Combined Company’s securities; • the Combined Company will be dependent on information technology and the Combined Company’s systems and infrastructure face certain risks, including from cybersecurity breaches and data leakage; • the Combined Company will generate a portion of revenue internationally and the Combined Company will be subject to various risks relating to international activities which could adversely affect operating results; • results of Combined Company clinical trials may be insufficient to obtain regulatory approval for any new product candidates; • the Combined Company will be subject to extensive governmental regulation, including the requirement of FDA approval or clearance, before any new product candidates may be marketed; • regulatory approval of the Combined Company’s product candidates may be withdrawn at any time; • federal regulatory reforms may adversely affect the Combined Company’s ability to sell products profitably; • failure to obtain regulatory approval in foreign jurisdictions may prevent the Combined Company from marketing products abroad; • if the Combined Company fails to obtain an adequate level of reimbursement for approved products by third party payers, there may be no commercially viable markets for approved products, or the markets may be much smaller than expected; • uncertainty surrounding and future changes to healthcare law in the United States may have a material adverse effect on the Combined Company; • if the Combined Company fails to comply with the United States Federal Anti-Kickback Statute, False Claims Act and similar state laws, the Combined Company could be subject to criminal and civil penalties and exclusion from the Medicare and Medicaid programs, which would have a material adverse effect on the business and results of operations; • if the Combined Company fails to comply with the HIPAA Privacy, Security and Breach Notification Regulations, as such rules become applicable to the Combined Company’s business, it may increase operational costs; • the Combined Company will face periodic reviews and billing audits from governmental and private payors and these audits could have adverse results that may negatively impact the business; • product quality or performance issues may be discovered through ongoing regulation by the FDA and by comparable international agencies, as well as through the Combined Company’s internal standard quality process; • the use of hazardous materials in Combined Company operation may subject the Combined Company to environmental claims or liability; • the protection of the Combined Company’s intellectual property will be critical to the Combined Company’s success and any failure on the Combined Company’s part to adequately protect those rights could materially adversely affect the business; • patent applications owned by or licensed to the Combined Company may not result in issued patents, and competitors may commercialize discoveries the Combined Company attempts to patent; • the Combined Company’s patents may not be valid or enforceable and may be challenged by third parties; • issued patents and patent licenses may not provide the Combined Company with any competitive advantage or provide meaningful protection against competitors; • the ability to market the products the Combined Company develops is subject to the intellectual property rights of third parties; • changes in the market’s expectations about the Combined Company’s operating results; • success of competitors of the Combined Company; • the Combined Company’s operating results failing to meet the expectation of securities analysts or investors in a particular period; • changes in financial estimates and recommendations by any securities analysts that may cover the Combined Company or the industries in which the Combined Company operates in general; • operating and stock price performance of other companies that investors deem comparable to the Combined Company; • changes in laws and regulations affecting the Combined Company’s business; • commencement of, or involvement in, litigation involving the Combined Company; 18 Table of Contents • changes in the Combined Company’s capital structure, such as future issuances of securities or the incurrence of additional debt; • the volume of shares of Class A Common Stock available for public sale by the Combined Company; • any major change in the post-Closing board of directors or management of the Combined Company; • sales of substantial amounts of Common Stock by directors, executive officers or significant stockholders of the Combined Company, or the perception that such sales could occur; and • general economic and political conditions such as recessions, pandemics, interest rates, fuel prices, international currency fluctuations and acts of war or terrorism. Broad market and industry factors may materially harm the market price of securities, irrespective of a company’s operating performance. The stock market in general, and Nasdaq in particular, have experienced price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the particular companies affected. The trading prices and valuations of these stocks, and of the Combined Company’s securities, may not be predictable. A loss of investor confidence in the market for the stock of other companies that investors perceive to be similar to the Combined Company could depress the Combined Company’s stock price regardless of its business, prospects, financial conditions, or results of operations. A decline in the market price of the Combined Company’s securities also could adversely affect the Combined Company’s ability to issue additional securities and to obtain additional financing in the future. Risks Related to our Business Our recurring losses from operations and dependency upon future issuances of equity or other financing to fund ongoing operations have raised substantial doubt as to our ability to continue as a going concern . We will be required to raise additional funds to finance our operations and remain a going concern; we may not be able to do so, and/or the terms of any financings may not be advantageous to us. The continuation of our business is dependent upon raising additional capital. We expect to devote substantial resources for the commercialization of UltraMIST and PACE which will require additional capital resources. We incurred a net loss of $25.8 million and $10.3 million for the years ended December 31, 2023, and 2022, respectively. The operating losses and the events of default on the Company’s notes payable indicate substantial doubt about the Company’s ability to continue as a going concern for a period of at least twelve months from the filing of this Annual Report Form 10-K. The Company is currently in default under the Senior Secured Note Payable issued to NH Expansion Credit Fund Holdings L.P. (“North Haven Expansion”) in August 2020 in the total principal amount of $15.0 million (the “Senior Secured Note”), the Convertible Promissory Note issued to Celularity Inc. (“Celularity”) in August 2020 in the total principal amount of $4.0 million (the “Celularity Note”), and the Convertible Promissory Note issued to HealthTronics, Inc. (“HealthTronics”) in August 2020 in the total principal amount of $1.4 million (the “HealthTronics Note”) and, as a result, is accruing interest at the default interest rate of an incremental 5% on the Senior Secured Note and the Celularity Note and an incremental 2% on the HealthTronics Note. The existing defaults under the Celularity Note and the HealthTronics Note relate to SANUWAVE’s failure to make required payments, and the existing defaults under the Senior Secured Note relate to (i) SANUWAVE’s failure to maintain minimum liquidity of $5.0 million and (ii) SANUWAVE’s defaults under the Celularity Note and HealthTronics Note. While the Celularity Note and the HealthTronics Note have already matured, and thus all amounts thereunder are already due and payable, if the Company does not regain compliance with the terms of the Senior Secured Note by April 30, 2024, North Haven Expansion will have the right to declare all obligations under the Senior Secured Note to be immediately due and payable. We expect to regain compliance with the terms of the Senior Secured Note upon the Closing of the Merger. On October 31, 2023, the Company entered into a letter agreement with HealthTronics, pursuant to which we agreed to pay HealthTronics the remaining unpaid principal amount of $1.4 million under the HealthTronics Note by the earlier of the Closing or March 31, 2024 in exchange for HealthTronics’ agreement to release all claims against the Company related to the HealthTronics Note. Management’s plans are to obtain additional capital in early 2024, primarily through closing the Merger Agreement. The Company could also obtain additional capital through the conversion of outstanding warrants, issuance of common or preferred stock, securities convertible into common stock, or secured or unsecured debt. However, because of our private placements in May 2023, December 2023 and January 2024 of Future Advance Convertible Promissory Notes and Common Stock Purchase Warrants, we are currently prohibited from incurring or guaranteeing most kinds of debt issued by public or private investors. These possibilities, to the extent available, may be on terms that result in significant dilution to the Company’s existing stockholders. In addition, there can be no assurances that the Company’s plans to obtain additional capital will be successful on the terms or timeline it expects, or at all. If these efforts are unsuccessful, the Company may be required to significantly curtail or discontinue operations or, if available, obtain funds through financing transactions with unfavorable terms. 19 Table of Contents The accompanying consolidated financial statements have been prepared in conformity with U.S. GAAP, which contemplate continuation of the Company as a going concern and the realization of assets and satisfaction of liabilities in the normal course of business. The carrying amounts of assets and liabilities presented in the consolidated financial statements do not necessarily purport to represent realizable or settlement values. The consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty. The Company’s consolidated financial statements do not include any adjustments relating to the recoverability of assets and classification of assets and liabilities that might be necessary should the Company be unable to continue as a going concern. 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. These material weaknesses are as follows: • Expertise and resources to analyze and properly apply U.S. GAAP to complex and non-routine transactions such as complex financial instruments and derivatives and complex sales distributing agreements with select vendors. • A lack of internal resources to analyze and properly apply U.S. GAAP to accounting for financial instruments included in service agreements with select vendors. • The Company has failed to design and implement controls around all accounting and IT processes and procedures and, as such, we believe that all its accounting and IT processes need to be re-designed and tested for operating effectiveness. We are taking certain measures to remediate these material weaknesses described above as described 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, 2023. In addition, due to the material weaknesses in internal control over financial reporting, we have also determined that our disclosure controls and procedures were ineffective as of December 31, 2023. The material weaknesses will not be considered remediated until management completes the design and implementation of the measures described above and the controls operate for a sufficient period of time and management has concluded, through testing, that these controls are effective. There can be no assurance as to when the material weaknesses will be remediated. At this time, we cannot provide an estimate of costs expected to be incurred in connection with implementing this remediation plan; however, 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 or avoid potential future material weaknesses to be identified in the future. 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, may result in additional 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. 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. We have experienced negative operating cash flows since our inception and have 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 will 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. In addition, because of our private placements in May 2023, December 2023, and January 2024, we are currently prohibited from incurring or guaranteeing most kinds of debt issued by public or private investors, which further constrains our options to raise capital. 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. 20 Table of Contents 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 expect it to continue to undergo rapid and significant technological change, and we expect competition to intensify as technological advances are made. 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. In addition, some of our suppliers have been and will continue to be affected by supply chain problems resulting from the pandemic. 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. 21 Table of Contents We have entered into an agreement with companies owned by a current board member and stockholder that could delay or prevent an acquisition of our Company and could result in the dilution of our stockholders in the event of our change of control. On February 13, 2018, we entered into an Agreement for Purchase and Sale, Limited Exclusive Distribution and Royalties, and Servicing and Repairs with Premier Shockwave Wound Care, Inc. (“PSWC”) and Premier Shockwave, Inc., each of which is owned by a member of the Company’s board of directors and an existing stockholder of the Company. Among other terms, the agreement contains provisions whereby in the event of a change of control of the Company (as defined in the agreement), the stockholders of PSWC have the right and option to cause the Company to purchase all of the stock of PSWC, and whereby the Company has the right and option to purchase all issued and outstanding shares of PSWC, in each case based upon certain defined purchase price provisions and other terms. While the agreement was amended effective November 1, 2023, to specify that the Business Combination does not constitute a change of control, such provision may have the effect of delaying or deterring any other change in control of the Company, and as a result could limit the opportunity for our stockholders to receive a premium for their shares of our common stock and could also affect the price that some investors are willing to pay for our common stock. In addition, in the event we do experience a change of control (other than the Business Combination), such provision may cause dilution of our existing stockholders if PSWC exercises its option to require the Company to purchase all issued and outstanding shares of PSWC and the Company finances some or all of such purchase price through equity issuances. The loss of our key management would likely hinder our ability to execute our business plan. As a small company with less than 40 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 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. 22 Table of Contents 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 five 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; • 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 the affirmative vote of a majority of directors then in office, even if 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 • unanticipated expenditures • product recall or seizure • interruption of manufacturing • operating restrictions • injunctions, and • criminal prosecutions. 23 Table of Contents 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 payers, 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 payers 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, 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 payers 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 payers 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. 24 Table of Contents 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 payors 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 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. 25 Table of Contents Failure to comply with the HIPAA Privacy, Security and Breach Notification Regulations, 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 PACE 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 Health Information Technology for Economic and Clinical Health (“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. 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 Centers for Medicare & Medicaid Services 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. 26 Table of Contents 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; • 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. 27 Table of Contents 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 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. 28 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. Risks Related to our Common Stock Our stock price is volatile. The market price of our common stock is volatile and could fluctuate widely in response to various factors, many of which are beyond our control, including the following: • our ability to obtain additional financing and, if available, the terms and conditions of the financing; • changes in our industry; • additions or departures of key personnel; • sales of our common stock; • our ability to execute our business plan; • operating results that fall below expectations; • period-to-period fluctuations in our operating results; 29 Table of Contents • new regulatory requirements and changes in the existing regulatory environment; and • general economic conditions and other external factors. In addition, the securities markets have from time-to-time experienced significant price and volume fluctuations that are unrelated to the operating performance of companies. These market fluctuations may also materially and adversely affect the market price of our common stock. There is currently a limited trading market for our common stock, and we cannot predict how liquid the market might become. To date, there has been a limited trading market for our common stock, and we cannot predict how liquid the market for our common stock might become. Until January 30, 2023, our common stock was quoted on the OTC Pink, which is an inter-dealer market that provides significantly less liquidity than the New York Stock Exchange or the Nasdaq Stock Market. We are currently listed on the OTCQB. The quotation of our common stock on the OTCQB does not assure that a meaningful, consistent, and liquid trading market exists. The market price for our common stock is subject to volatility and holders of our common stock may be unable to resell their shares at or near their original purchase price, or at any price. In the absence of an active trading market: • investors may have difficulty buying and selling, or obtaining market quotations for our common stock; • market visibility for our common stock may be limited; and • a lack of visibility for our common stock may have a depressive effect on the market for our common stock. As an issuer of “penny stock”, the protection provided by the Federal securities laws relating to forward-looking statements does not apply to us. Although Federal securities laws provide a safe harbor for forward-looking statements made by a public company that files reports under the Federal securities laws, this safe harbor is not available to issuers of penny stocks. As a result, we will not have the benefit of this safe harbor protection in the event of any legal action based upon a claim that the material provided by us contained a material misstatement of fact or was misleading in any material respect because of our failure to include any statements necessary to make the statements not misleading. Such an action could hurt our financial condition. 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. We have never paid cash dividends on our common stock and do not anticipate doing so in the foreseeable future. The payment of dividends on our common stock will depend on earnings, financial condition and other business and economic factors affecting us at such time as our board of directors may consider relevant. If we do not pay dividends, our common stock may be less valuable because a return on your investment will only occur if our stock price appreciates. The rights of the holders of common stock may be impaired by the potential issuance of preferred stock. Our board of directors has the right, without stockholder approval, to issue preferred stock with voting, dividend, conversion, liquidation, or other rights which could adversely affect the voting power and equity interest of the holders of common stock, which could be issued with the right to more than one vote per share, and could be utilized as a method of discouraging, delaying or preventing a change of control. The possible negative impact on takeover attempts could adversely affect the price of our common stock. We have not sought an advisory stockholder vote to approve the compensation of our named executive officers. Rule 14a-21 under the Exchange Act requires us to seek a separate stockholder advisory vote at our annual meeting at which directors are elected to approve the compensation of our named executive officers, not less frequently than once every three years (say-on-pay vote), and, at least once every six years, to seek a separate stockholder advisory vote on the frequency with which we will submit advisory say-on-pay votes to our stockholders (say-on-frequency vote). We have not submitted to our stockholders a say-on-pay vote to approve an advisory resolution regarding our compensation program for our named executive officers, or a say-on-frequency vote. Consequently, the board of directors has not considered the outcome of our say-on-pay vote results when determining future compensation policies and pay levels for our named executive officers. 30 Table of Contents If the Company fails to comply with our SEC filing obligations, our stock may become subject to limitations or reduction in stock price, liquidity, or volume. Rule 15c2-11 under the Exchange Act (the “Rule”) governs the publication of quotations in over-the-counter (“OTC”) markets. On September 16, 2020, the SEC adopted amendments to the Rule which prohibits broker-dealers from publishing or submitting for publication a quote for an issuer’s securities unless they are based on current publicly available information about the issuer. The amended Rule also limits the Rule’s “piggyback” exception, which allows broker-dealers to publish quotations for a security in reliance on the quotations of a broker-dealer that initially performed the information review required by the Rule, to issuers with current publicly available information or issuers that are up to date in their Exchange Act reports. The practical impact of these changes requires us to maintain a level of periodic disclosure. However, we did not timely file with the SEC our Annual Report on Form 10-K for the year ended December 31, 2020, or our Quarterly Report on Form 10-Q for the quarters ended March 31, 2021 or June 30, 2021. As a result, our stock was removed from the OTC Bulletin Board on September 28, 2021, which limited the ability of broker-dealers to sell our securities and the ability of stockholders to sell their securities in the secondary market. Upon filing the Quarterly Report on Form 10-Q for the quarter ended September 30, 2021, we were allowed to return to the OTC Pink and subsequently uplisted to the OTCQB. While trading on the OTCQB, and especially if we are removed from the OTCQB in the future, the market liquidity for our securities could be severely adversely affected by limiting the ability of broker-dealers to sell our securities and the ability of stockholders to sell their securities in the secondary market. Item 1B. UNRESOLVED STAFF COMMENTS None. Item 1C. CYBERSECURITY Our management and Board of Directors (the “Board”) recognize the importance of maintaining the security and resiliency of our cybersecurity environment to deliver on the expectations of our customers, business partners, employees, and investors. The Board is involved in our risk management practices. Overall, the purpose of our information security program is to protect the confidentiality, integrity and availability of our systems and data, along with the safe operation of our systems. Technical safeguards We deploy technical safeguards that are designed to protect our systems from cybersecurity threats, including firewalls, anti-malware software, and authentication and authorization controls. Security awareness and training We provide ongoing security awareness and training to educate internal users on how to identify and report potential issues. Phishing emails are discussed on a regular basis with employees to ensure proper protocols are followed. We also provide periodic updates to employees on emerging cybersecurity trends and ways to protect themselves and our company. Governance of Cybersecurity Risks The Audit Committee of the Board has the primary responsibility for oversight and review of guidelines and policies with respect to risk assessment and risk management, including cybersecurity. The Company’s Chief Executive Officer, President, and Chief Financial Officer are responsible for assessing and managing cybersecurity risks. The Company’s management periodically reports on cybersecurity issues and presents information to our Audit Committee as well as our full Board, as appropriate, on cybersecurity matters. Upon verifying that a cybersecurity incident has occurred or is occurring, the Chief Executive Officer, President and Chief Financial Officer will promptly conduct a preliminary assessment of the severity level of the cybersecurity incident. Following this assessment, the Chief Executive Officer will determine whether to report the cybersecurity incident to the Audit Committee, who will then report such cybersecurity incident to the Board as the chair deems appropriate. Material Impact of Cybersecurity Risks We have not experienced a material information security breach incident, and we are not aware of any cybersecurity risks that are reasonably likely to materially affect our business. However, future incidents could have a material impact on our business strategy, results of operations or financial condition. For additional discussion of the risks posed by cybersecurity threats, see “Item 1A. Risk Factors— Risks to our Business— We are dependent on information technology and our systems and infrastructure face certain risks, including from cybersecurity breaches and data leakage.” 31 Table of Contents Item 2. PROPERTIES Our primary corporate and operations office is a leased facility in Eden Prairie, Minnesota, consisting of 8,199 square feet of space under a lease which expires on August 31, 2025. Under the terms of the lease, we pay monthly rent, subject to a 2.5% adjustment on an annual basis. We also have a research and development office in a leased facility in Alpharetta, Georgia, consisting of 4,332 square feet of space under a lease that expires in July 2027. Item 3. 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. Acquisition Dispute - In May 2021, the Company received notification alleging that it is not in compliance with the license agreement with Celularity entered into in connection with the acquisition of the UltraMIST assets. The Company has responded and asserted that the Company is not in breach and that the supplier has breached various agreements. Any potential impact to the Company cannot be fully determined at this time. Item 4. MINE SAFETY DISCLOSURE Not applicable. PART II Item 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Market Information The Company’s common stock is quoted on the OTCQB under the symbol “SNWV”. The quotations reflect inter-dealer prices, without retail mark-up, mark-down, or commissions, and may not necessarily represent actual transactions. Holders of Common Stock As of December 31, 2023, there were 1,140,559,527 shares of common stock outstanding and approximately 238 holders of record of the Company’s common stock. Dividends The Company did not pay a cash dividend in 2023 or 2022. The Company intends to retain future earnings, if any, to finance the expansion of its business. The Company does not anticipate paying any cash dividends in the foreseeable future. Item 6. [Reserved] Not applicable. 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, 2023, and 2022. You should read this discussion and analysis in conjunction with our consolidated financial statements and related notes thereto on December 31, 2023, and 2022, and for years 2023, and 2022, which are presented within Part II Item 8. “Financial Statements and Supplementary Data" in this Annual Report on Form 10-K. 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. 32 Table of Contents Executive Summary We realized significant revenue growth during the year ended December 31, 2023, with a 22% growth in revenue to $20.4 million for the year ended December 31, 2023, as compared to $16.7 million in 2022. Gross margins also decreased to 70% from 74% in 2022. As the Company continues to focus on profitable growth, we have also reduced our operating loss by 94% to $0.5 million for the year ended December 31, 2023. Net loss for the year ended December 31, 2023, was $25.8 million, or ($0.03) per basic and diluted share, compared to a net loss of $10.3 million, or ($0.02) per basic and diluted share, for the year ended December 31, 2022, a variance of $15.5 million, which was largely driven by a non-cash change in the fair value of derivatives. Operating loss for the year ended December 31, 2023, was $540 thousand, compared to $9.0 million for the year ended December 31, 2022. We continue to focus on profitable growth and reduction in operating expenses. We believe these improvements sets the stage for additional growth as we head into 2024. Merger Agreement with SEPA On August 23, 2023, we entered into an Agreement and Plan of Merger (the “ Merger Agreement ”) by and among SEP Acquisition Corp., a Delaware corporation (“ SEPA ”), SEP Acquisition Holdings Inc., a Nevada corporation, and a wholly owned subsidiary of SEPA (“ Merger Sub ”). Pursuant to the terms of the Merger Agreement, a business combination between the Company and SEPA (the “ Merger ”) will be affected. More specifically, and as described in greater detail below, at the effective time of the Merger (the “ Effective Time ”): • Merger Sub will merge with and into the Company, with the Company being the surviving company following the merger. • Each issued and outstanding share of the Company common stock will automatically be converted into Class A common stock of SEPA, par value $0.0001 per share, at the Conversion Ratio (as defined in the Merger Agreement); and • Outstanding Company convertible securities of the Company will be assumed by SEPA and will be converted into the right to receive Class A Common Stock of SEPA. Pursuant to the terms of the Merger Agreement, the holders of (i) Company common stock, (ii) in the money options to purchase Company common stock, (iii) in the money warrants to purchase Company common stock, and (iv) convertible promissory notes, collectively will be entitled to receive 7,793,000 shares of Class A Common Stock of SEPA. Out-of-the-money options and out-of-the-money warrants will be assumed by SEPA and converted into options or warrants, respectively, exercisable for shares of Class A Common Stock based on the Conversion Ratio; however, such out-of-the-money options and out-of-the-money warrants shall not be reserved for issuance from the Merger Consideration. 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 one-time charges. EBITDA and Adjusted EBITDA should not be considered as alternatives to net loss as a measure of financial performance or any other performance measure derived in accordance with GAAP, and they should not be construed as an inference that our future results will be unaffected by unusual or non-recurring 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 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 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 GAAP. Some of these limitations are that EBITDA and Adjusted EBITDA: 33 Table of Contents • Do not reflect every expenditure, future requirements for capital expenditures or contractual commitments. • Do not reflect all changes in our working capital needs. • Do not reflect interest expense, or the amount necessary to service our outstanding debt. As presented in the GAAP to Non-GAAP Reconciliations section below, our non-GAAP financial measure excludes the impact of certain charges that contribute to our net loss (Non-GAAP Adjustments).

The increase in net sales was primarily driven by the growth in quantity of disposables sold, which increased by 9% in 2023 as compared to 2022. Pricing of the UltraMIST ® system and disposables also showed growth in 2023 as compared to 2022, disposables average selling price increased over 10% in 2023, and system revenue increased 28% in 2023. Revenue from UltraMIST totaled 90% of total revenue in 2023 and 2022. 34 Table of Contents Cost of Revenue Cost of revenues for the year ended December 31, 2023, was $6.0 million, compared to $4.3 million for the same period in 2022. Gross profit as a percentage of revenues was 70% for the year ended December 31, 2023, compared to 74% for the same period in 2022. This decrease in gross margin was largely driven by increased one time inventory write offs and costs to support our growth and alleviate our inventory constraint in 2023. General and Administrative General and administrative expenses for the year ended December 31, 2023, were $8.7 million as compared to $12.6 million for the same period in 2022, a decrease of $3.9 million, or 31%. The decrease in 2023 as compared to 2022 was primarily due to the higher legal costs related to patent work and securities work incurred in 2022. Selling and Marketing Selling and marketing expenses for the year ended December 31, 2023, were $4.9 million as compared to $7.4 million for the same period in 2022, a decrease of $2.6 million, or 34%. The year-over-year decrease in sales and marketing expenses in 2023 was a result of cost saving initiatives taken by management. Research and Development Research and development expenses for the year ended December 31, 2023, were $0.6 million, compared to $0.6 million for the same period in 2022. The research and development costs in 2023 remained consistent with the costs in 2022. Other Income (Expense), net Other expense, net consists of the following: For the years ended December 31, Change 2023 2022 $ % Interest expense $ (15,623 ) $ (14,132 ) $ (1,491 ) 11 % Change in fair value of derivatives (9,621 ) 16,654 (26,275 ) nm Loss on issuance of debt - (3,434 ) 3,434 -100 % Gain/(loss) on extinguishment of debt - (418 ) 418 nm Other expense (19 ) (9 ) (10 ) nm Other expense, net $ (25,263 ) $ (1,339 ) $ (23,924 ) nm nm - not meaningful Other expenses totaled $25.2 million for the year ended December 31, 2023, as compared $1.3 million for the same period in 2022, an increase of $23.9 million. The increase was primarily driven by an increased loss from the change in the fair value of derivative liability of $26.3 million, offset by a decrease in loss on issuance of debt along with the loss on extinguishment of debt. The increased interest expense of $1.5 million was the result of higher levels of debt outstanding during 2023, due to new issuances of convertible debt, compared with 2022. The change in fair value of the derivative liability relates to warrants issued during 2023 and 2022 with the convertible debt. Liquidity and Capital Resources Since inception, we have incurred losses from operations each year. As of December 31, 2023, we had an accumulated deficit of $220.0 million. Historically, our operations have primarily been funded from the sale of capital stock, notes payable, and convertible debt securities. In August 2022,November 2022, May 2023 and December 2023, we entered into a Securities Purchase Agreements (the “Purchase Agreements”), for the sale in a private placement of (i) Future Advance Convertible Promissory Notes (the “Notes”) in an aggregate principal amount of $16.2 million in August 2022,$4.0 million in November 2022, $1.2 million in May 2023, and $1.9 million in December 2023 (ii) Common Stock Purchase Warrants to purchase an additional 581.6 million shares of common stock with an exercise price of $0.067 per share and (iii) Common Stock Purchase Warrants to purchase an additional 581.6million shares of common stock with an exercise price of $0.04 per share. 35 Table of Contents Pursuant to the Notes, the Company promised to pay in cash and/or in shares of common stock, at a conversion price of $0.04 (the “Conversion Price”), the principal amount and interest at a rate of 15% per annum on any outstanding principal. The Conversion Price of the Notes is subject to adjustment, including if the Company issues or sells shares of common stock for a price per share less than the Conversion Price of the Notes or if the Company lists its shares of common stock on The Nasdaq Capital Market and the average volume weighted average price of such common stock for the five trading days preceding such listing is less than $0.04 per share; provided, however, that the Conversion Price shall never by less than $0.01. The Notes contain customary events of default and covenants, including limitations on incurrences of indebtedness and liens. In August 2023 and November 2023, the Company utilized its election to convert the August and November issued 2022 Convertible Notes Payable into shares of common stock upon the Notes’ maturity. The August notes totaling $16.2 million in principal and $2.4 million in interest were converted to 464,440,813 shares of common stock. The November notes totaling $4.0 million in principal and $0.6 million in interest were converted to 114,481,063 shares of common stock. In July 2023, we issued Asset-Backed Secured Promissory Notes in an aggregate principal amount of $4.6 million to certain accredited investors at an original issue discount of 33.33%. These notes bear an interest rate of 0% per annum and matured on January 21, 2024. We received total proceeds of approximately $3.0 million. We also entered into a side letter, pursuant to which, we issued Future Advance Convertible Promissory Notes, on January 21, 2024, with the same principal amount as the principal amount of such Notes, plus any accrued and unpaid interest and two Common Stock Purchase Warrants, substantially in the forms of the Notes and Common Stock Purchase Warrants disclosed in the previous paragraphs. In August 2020, the Company issued a Senior Secured Promissory Note Payable (the “Senior Secured Note”) to NH Expansion Credit Fund Holdings L.P. pursuant to which the Company had outstanding debt of $21.5 million as of December 31, 2023. Interest is charged at the greater of the prime rate or 3% plus 9%, paid quarterly. As of December 31, 2023, the Company is in default of the minimum liquidity provisions on the Senior Secured Note and, as a result, is accruing interest at the default interest rate of an incremental 5%. Interest expense on the Senior Secured Note totaled $6.9 million and $5.9 million for the years ended December 31, 2023, and 2022, respectively. See Notes 10, 11 and 12 to the consolidated financial statements in Part II Item 8. “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K for additional information regarding additional debt commitments, the convertible notes and accompanying warrants issued in May and December 2023, $4.5 million in asset-backed secured promissory notes, and the Senior Secured Note. The following table presents summarized cash flow information: For the period ended December 31, (in thousands) 2023 2022 Cash flows used by operating activities $ (4,538 ) $ (17,169 ) Cash flows provided by investing activities $ 21 $ 332 Cash flows provided by financing activities $ 5,211 $ 17,384 Cash Flows from Operating Activities We have improved our cash flow from operations in 2023 as compared to 2022, which was driven by increased emphasis on improved cash management and operating expense management. We also invested in our inventory in 2023, increasing our inventory levels by $2 million for the year ended December 31, 2023. Additional volatility in adjustments of cash flows from operations is the change in fair value of derivative liabilities connected to our convertible debt and warrants issued with the August and November 2022, and May and December 2023 financings. The Company recognized a loss on these liabilities of $9.6 million for the year ended December 31, 2023, as compared to a gain of $16.7 million for the year ended December 31, 2022. Cash Flows Provided by Financing Activities Cash flows provided by financing activities decreased primarily due to the improvement of operating cash flows which reduced our required cash to fund our growth and operations. For the year ended December 31, 2023, we received proceeds of $6.0 million from the issuance of the convertible promissory notes and asset backed secured promissory notes discussed above in this section, Liquidity and Capital Resources, as compared to $16.2 million for the year ended December 31, 2022. 36 Table of Contents Going Concern The continuation of our business is dependent upon raising additional capital to fund operations. This, as well as the events of default on various notes payable, raise substantial doubt about our ability to continue as a going concern for a period of at least twelve months. Management plans to obtain additional capital in 2024 through the completion of the Merger Agreement. We could also obtain additional capital through the conversion of outstanding warrants, issuance of common or preferred stock, securities convertible into common stock, or secured or unsecured debt. These possibilities, to the extent available, may be on terms that result in significant dilution to our existing stockholders. Although no assurances can be given that our plans to obtain additional capital will be successful or on the terms or timeline we expect, or at all, management believes that potential additional issuances of equity or other potential financing transactions, as discussed above, should provide the necessary funding for us over the next 12 months. If these efforts are unsuccessful, we may be required to significantly curtail or discontinue operations or obtain funds through financing transactions with unfavorable terms. See Note 2 to the consolidated financial statements in Part II Item 8. “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K for additional information on our ability to continue as a going concern. Critical Accounting Policies and Estimates 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. Derivative Liabilities from Embedded Conversion Options and Warrants The Company classified certain convertible instruments as having embedded conversion options which qualified as derivative financial instruments to be separately accounted for. The Company also determined that certain warrants also qualified as derivative financial instruments. Various valuation models were used to estimate the fair value of these derivative financial instruments that are classified as derivative liabilities on the consolidated balance sheets. The models include subjective input assumptions that can materially affect the fair value estimates and as such are subject to uncertainty. Our significant input assumptions are discussed in Note 13 to the consolidated financial statements in Part II Item 8. “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K. 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. 37 Table of Contents Item 8 FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA Page Consolidated Financial Statements Report of Independent Registered Public Accounting Firm (PCAOB ID: 688 ) F-1 Consolidated Balance Sheets as of December 31, 2023 and 2022 F-3 Consolidated Statements of Comprehensive Loss for the years ended December 31, 2023 and 2022 F-4 Consolidated Statements of Stockholders’ Deficit for the years ended December 31, 2023 and 2022 F-5 Consolidated Statements of Cash Flows for the years ended December 31, 2023 and 2022 F-6 Notes to Consolidated Financial Statements F-7 38 Table of Contents REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Stockholders and Board of Directors of SANUWAVE Health, Inc. Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of SANUWAVE Health, Inc. (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of comprehensive loss, stockholders’ deficit, and cash flows for each of the two years in the period ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America. Explanatory Paragraph – Going Concern The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 2, the Company has incurred recurring losses and needs to raise additional funds to meet its obligations, sustain its operations, and to resolve the events of default on the Company’s debt. These conditions raise substantial doubt about the Company's ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 2. The consolidated 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 audits. 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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits 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 audits, 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 audits 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 audits 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 audits provide a reasonable basis for our opinion. Critical Audit Matters The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Valuation of Financial Instruments (Embedded Conversion Options and Warrant Liability) Critical Audit Matter Description As described in Notes 11, 12, and 13 to the consolidated financial statements, the Company has entered into Securities Purchase Agreements and Asset-Backed Secured Promissory Notes (the “Transactions”). The Company determined certain embedded conversion features associated with the Transactions were required to be bifurcated and recorded at fair value. The warrants issued in connection with the Transactions were also recorded at fair value. The fair value of the embedded conversion options and the warrant liability were valued using valuation techniques and key inputs as described in the footnotes. F-1 Table of Contents The principal considerations for our determination that the valuation of the embedded conversion options and warrant liability is a critical audit matter were the significant judgments made by management in determining the fair value of the embedded conversion options and warrant liability. This in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions. The audit also involved the use of professionals with specialized skill and knowledge. How the Critical Audit Matter was Addressed in the Audit Our audit procedures related to the valuation of the financial instruments included the following, among others: ◾ We obtained an understanding of the design of the Company's controls over valuation of financial instruments, including controls over management's review of the valuation models, and the significant assumptions used in determining the fair value of the financial instruments. ◾ With assistance of our valuation specialists, we audited the fair value of the embedded conversion options and warrant liability, valuation methodology, and key assumptions used in determining the fair value of the embedded conversion options and warrant liability by: a. Evaluating the appropriateness of the valuation models and techniques used in determining the fair value; b. Assessing the reasonableness of the significant valuation inputs, including the probability weighted expected value considering the merger agreement with SEPA Acquisition Corp. (“SEPA”), the risk adjusted expected exchange ratio, the value of SEPA’s Class A common stock, the expected timing of the closing of the merger, and the probability of the merger closing; c. Assessing that the significant valuation assumption inputs, in the Black Scholes valuation model, of the discounted stock price and implied volatility are consistent with those that would be used by market participants through the testing of source information; and d. Checking the mathematical accuracy of the calculation, developing independent estimates and comparing to those selected by management, where applicable, and recalculating management’s fair value, verifying it was reasonable. ◾ We audited the completeness and accuracy of the underlying data supporting the significant valuation assumption inputs. /s/ Marcum llp Marcum LLP We have served as the Company’s auditor since 2018.

F-6 Table of Contents SANUWAVE HEALTH, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS December 31, 2023 and 2022 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 noninvasive and biological response activating medical systems for the repair and regeneration of skin, musculoskeletal tissue, and vascular structures. 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 for 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. 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 loss in the consolidated statements of comprehensive loss and as cumulative translation adjustments in accumulated other comprehensive loss in the consolidated balance sheets. Segment information - We have determined that we have one operating segment. Our revenues are primarily generated from sales in the United States. All significant expenses are generated, and all significant assets are located in the United States. Reclassification - Certain accounts in the prior period consolidated financial statements 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. Going Concern Our recurring losses from operations, the events of default on the Company’s notes payable, and dependency upon future issuances of equity or other financing to fund ongoing operations have raised substantial doubt as to our ability to continue as a going concern for a period of 12 months from the filing of the Form 10-K. We will be required to raise additional funds to finance our operations and remain a going concern; we may not be able to do so, and/or the terms of any financings may not be advantageous to us. The continuation of our business is dependent upon raising additional capital. We expect to devote substantial resources for the expansion and continued commercialization of our UltraMIST and PACE systems which will require additional capital resources. The operating losses and the events of default on the Company’s notes payable indicate substantial doubt about the Company’s ability to continue as a going concern for a period of at least twelve months from the filing of this Annual Report on Form 10-K. Management’s plans are to obtain additional capital in 2024 primarily through the closure of the Merger Agreement, as described in Note 4. The Company could also obtain funding through the conversion of outstanding warrants, issuance of common or preferred stock, securities convertible into common stock, or secured or unsecured debt. These possibilities, to the extent available, may be on terms that result in significant dilution to our existing stockholders. Although no assurances can be given, management believes that potential additional issuances of equity or other potential financing transactions if obtained as discussed above should provide the necessary funding for us. If these efforts are unsuccessful, we may be required to significantly curtail or discontinue operations or obtain funds through financing transactions with unfavorable terms. The accompanying consolidated financial statements have been prepared in conformity with U.S. GAAP, which contemplate continuation of the Company as a going concern and the realization of assets and satisfaction of liabilities in the normal course of business. The carrying amounts of assets and liabilities presented in the consolidated financial statements do not necessarily purport to represent realizable or settlement values. The consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty. Our consolidated financial statements do not include any adjustments relating to the recoverability of assets and classification of assets and liabilities that might be necessary should we be unable to continue as a going concern. F-7 Table of Contents 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 intangible assets, the determination of the valuation allowances for deferred taxes, litigation contingencies, estimated fair value of stock-based compensation, and the estimated fair value of embedded financial instruments, including warrants and embedded conversion options. 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. The allowance is based on the assessment of the following factors: customer creditworthiness; historical payment experience; age of outstanding receivables. 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. Inventory - Inventory consists of purchased medical equipment and parts and is stated at the lower of average cost, which is valued using the first in, first out (“FIFO”) method, or net realizable value less allowance for selling and distribution expenses. The Company analyzes its inventory levels and writes down inventory that has, or is expected to, become obsolete. 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 Accounting Standards Codification (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 accumulated 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, 2023, and 2022. 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 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 determines whether an arrangement is a lease at inception. When lease arrangements include lease and non-lease components, the Company accounts for lease and non-lease components (e.g. common area maintenance) separately based on their relative standalone prices. For leases where the Company is the lessee, Right of Use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As the Company’s leases did not provide an implicit interest rate, the Company used the equivalent borrowing rate for a secured financing with the term of equal to the remaining life of the lease at inception. Any lease arrangements with an initial term of 12 months or less are not recorded on our consolidated balance sheets, and the Company recognizes lease costs for these lease arrangements on a straight-line basis over the lease term. In the event a lease arrangement would provide us with options to exercise one or more renewal terms or to terminate the lease arrangement, we would include these options when we are reasonably certain to exercise them in the lease term used to establish ROU assets and lease liabilities. None of our lease agreements include an option to purchase the leased asset, residual value guarantees, or material restrictive covenants. The Company has other lease arrangements that are adjusted periodically based on an inflation index or rate. The future variability of these payments and adjustments are unknown, and therefore they are not included as minimum lease payments used to determine ROU assets and lease liabilities. Variable rental payments are recognized in the period in which the obligation is incurred. F-8 Table of Contents 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. Sequencing policy – The Company follows a sequencing policy for which in the event partial reclassifications of contracts subject to ASC Topic 815-40-25, Derivatives and Hedging , is necessary, due to the Company’s inability to demonstrate it has sufficient authorized shares, shares will be allocated based on earliest issuance date of potentially dilutive instruments with the earliest grants receiving first allocation of shares. 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 loss. This debt discount is reported as a reduction of the related debt liability. Contract Liabilities – Device product sales are bundled with an initial one-year warranty and the Company offers a separately priced multi-year warranty. Because the warranty represents an obligation, revenue is deferred as a contract liability and recognized over the time that the Company satisfies its performance obligations, which is generally the warranty term. Revenue Recognition - The core principle of ASC Topic 606 “Revenue from Contracts with Customers” (“ASC 606”) requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The Company allocates the transaction price to all contractual performance obligations included in the contract. If a contract has more than one performance obligation, we allocate the transaction price to each performance obligation based on standalone selling price, which depicts the amount of consideration we expect to be entitled in exchange for satisfying each performance obligation. The Company recognizes revenue primarily from the following types of contracts: System Sales, Consumables and Part Sales - System sales, accessory and part sales include devices and applicators (new and refurbished). Performance obligations are satisfied at the point in time when the customer obtains control of the goods, which is generally at the point in time that the product is shipped. Licensing Fees - Licensing transactions include distribution licenses and intellectual property licenses. Licensing revenue is recognized as the Company satisfies its performance obligations, which may vary with the terms of the licensing agreement. Other Revenue - Other revenue primarily includes warranties, repairs, and billed freight. The Company allocates the device sales price to the product and the embedded warranty by reference to the stand-alone extended warranty price. Warranty revenue is recognized over the time that the Company satisfies its performance obligations, which is generally the warranty term. Repairs (parts and labor) and billed freight revenue are recognized at the point in time that the service is performed, or the product is shipped, respectively. F-9 Table of Contents Shipping and handling costs - Shipping charges billed to customers are included in revenues. Shipping and handling costs incurred have been recorded in cost of goods sold totaling $ 484 thousand and $ 324 thousand for the years ended December 31, 2023, and 2022, respectively. Research and development - Research and development costs are expensed as incurred. Research and development costs include costs of research, engineering, and technical activities to develop a new product, researching an expanded product use or making significant improvements to existing products, including the costs of clinical development. Stock-based compensation - The Company uses the fair value method of accounting for its employee stock option program. Stock-based compensation expense for all stock-based payment awards is based on the estimated fair value of the award measured on the grant date. The Company recognizes the estimated fair value of the award as compensation cost on a straight-line basis over the requisite service period of the award, which is generally the option vesting term. The Company generally issues new shares of common stock to satisfy option and warrant exercises. The expected life of options granted represents the period of time that options granted are expected to be outstanding and are derived from the contractual terms of the options granted calculated under the simplified method. The risk-free rate for periods within the contractual life of the option is based on the United States Treasury yield curve in effect at the time of the grant. The expected volatility is based on the average volatility of the Company’s common stock. The expected dividend yield is based on our historical dividend experience, however, since our inception, we have not declared dividends. Forfeitures are recognized as they occur. Comprehensive income (loss) – Comprehensive income (loss) results from the translation of the Company’s foreign entity’s financial statements from their functional currency to U.S. dollars for consolidation in the accompanying consolidated financial statements. New accounting pronouncements - In December 2023, the FASB issued ASC Update No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. Update No. 2023-09 aims to enhance the transparency and decision usefulness of income tax disclosures. Update No. 2023-09 modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state, and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. Update No. 2023-09 is effective for fiscal years beginning after December 15, 2024. We expect to adopt Update No. 2023-09 prospectively. We are currently evaluating the potential impact of adopting this new guidance on our consolidated financial statements and related disclosures. In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which was subsequently revised by ASU 2018-19. The ASU introduces a new model for assessing impairment of most financial assets. Entities are required to use a forward-looking expected loss model, which replaces the current incurred loss model, resulting in earlier recognition of allowance for losses. The Company adopted this ASU in January 2023, and there was no material impact on the consolidated financial statements. 4. Merger Agreement On August 23, 2023, the Company entered into an Agreement and Plan of Merger (the “ Merger Agreement ”) by and among SEP Acquisition Corp., a Delaware corporation (“ SEPA ”), SEP Acquisition Holdings Inc., a Nevada corporation and a wholly owned subsidiary of SEPA (“ Merger Sub ”). Pursuant to the terms of the Merger Agreement, a business combination between the Company and SEPA (the “ Merger ”) will be affected. More specifically, and as described in greater detail below, at the effective time of the Merger (the “ Effective Time ”): • Merger Sub will merge with and into the Company, with the Company being the surviving company following the merger. • Each issued and outstanding share of the Company’s common stock, will automatically be converted into Class A common stock of SEPA, par value $ 0.0001 per share (the “Class A Common Stock”), at the Conversion Ratio (as defined in the Merger Agreement); and • Outstanding convertible securities of the Company will be assumed by SEPA and will be converted into the right to receive Class A Common Stock of SEPA. If the Merger Agreement is consummated SEPA will acquire 100 % of the Company’s issued and outstanding equity securities. The proposed merger will be accounted for as a “reverse recapitalization” in accordance with US GAAP. Under the reverse recapitalization model, the transaction will be treated as the Company issuing equity for the net assets of SEPA, with no goodwill or intangible assets recorded. Under this method of accounting, SEPA will be treated as the acquired company for financial reporting purposes. This determination is primarily based on the fact that following the merger, the Company’s stockholders are expected to have a majority voting power of the combined company, approximately 69 – 70 %, the Company will comprise all of the ongoing operations of the combined company, Company representatives will comprise a majority of the governing body of the combined company, and the Company’s senior management will comprise all of the senior management of the combined company. As a result of the merger, SEPA will be renamed Sanuwave Health, Inc. F-10 Table of Contents Merger Consideration - The consideration to be delivered to the Company’s securityholders by SEPA in connection with the consummation of the Merger (the “Closing”) will consist solely of 7,793,000 shares of Class A Common Stock and, in the case of certain Securityholders, of securities convertible into or exercisable for new shares of Class A Common Stock reserved for issuance from the merger consideration (the “Merger Consideration”). The Merger Consideration deliverable to the Company’s stockholders will be allocated pro rata based on their ownership after giving effect to the required conversion or exercise, as applicable, of all the outstanding convertible notes, in-the-money options, and in-the-money warrants immediately prior to the Closing. Out-of-the-money options and out-of-the-money warrants will be assumed by SEPA and converted into options or warrants, respectively, exercisable for shares of Class A Common Stock based on the Conversion Ratio; however, such out-of-the-money options and warrants shall not be reserved for issuance from the Merger Consideration. Conditions to Closing - The Merger Agreement contains customary conditions to Closing, including the following mutual conditions of the parties (unless waived): (i) approval of the stockholders of the Company and SEPA; (ii) approvals of any required governmental authorities; (iii) no law or order preventing the Transactions; (iv) the filing of the Charter Amendments; (v) the appointment of SEPA’s post-closing board of directors; (vi) the Registration Statement having been declared effective by the SEC; (vii) approval of the Class A Common Stock of SEPA for listing on Nasdaq; (viii) holders of 80 % or more of the Company’s convertible notes with a maturity date occurring after the date of the Closing (the “ Closing Date ”), measured by number of shares into which such convertible notes may be converted, agreeing to convert their convertible notes into shares common stock immediately prior to the Effective Time; and (ix) holders of 80 % or more of the Company’s warrants that would be outstanding on the Closing Date, measured by number of shares subject to all such warrants in the aggregate, agreeing to convert their warrants into shares of common stock immediately prior to the Effective Time. In addition, unless waived by the Company, the obligations of the Company to consummate the business combination are subject to the satisfaction of the following additional Closing conditions, in addition to the delivery by SEPA of customary certificates and other Closing deliverables: (ii) SEPA having performed in all material respects its obligations and complied in all material respects with its covenants and agreements under the Merger Agreement required to be performed or complied with by it on or prior to the Closing Date; (iii) SEPA having delivered a fairness opinion of the Purchaser Financial Advisor (as defined in the Merger Agreement), in form and substance reasonably satisfactory to the Company; (iv) SEPA having, at the Closing, at least $ 12,000,000 in cash and cash equivalents, including funds remaining in the trust account (after giving effect to the completion and payment of any redemptions) and the proceeds of any PIPE Investment; and other customary conditions to Closing as defined in the Merger Agreement. In February 2024, the Company amended the Merger Agreement to extend the date after which the Company or SEPA, in its discretion, can elect to terminate the Merger Agreement if any of the conditions to closing of the other party have not been met or waived, from February 28, 2024 to April 30, 2024. 5. Loss per Share The net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of shares outstanding for the years ended December 31, 2023, and 2022. In accordance with ASC Topic 260-10-45-13, Earnings Per Share , the weighted average of number of shares outstanding includes outstanding common stock and shares issuable for nominal consideration. Accordingly, warrants issued with a $ 0.01 per share exercise price, are included in weighted average shares outstanding as follows: (in thousands) December 31, 2023 December 31, 2022 Common shares 772,160 526,530 Common shares issuable assuming exercise of nominally priced warrants 21,691 22,941 Weighted Average Shares Outstanding 793,851 549,471 Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock and dilutive common stock equivalents outstanding. To the extent that securities are “anti-dilutive,” they are excluded from the calculation of diluted net loss per share. As a result of the net loss for the years ended December 31, 2023, and 2022, all potentially dilutive shares were anti-dilutive and therefore excluded from the computation of diluted net loss per share. Anti-dilutive equity securities consist of the following: (in thousands) December 31, 2023 December 31, 2022 Common stock options 16,287 21,246 Common stock purchase warrants 1,199,882 1,186,522 Convertible notes payable, including interest 161,773 603,425 1,377,942 1,811,193 F-11 Table of Contents 6.

Factoring Liabilities In June 2021, the Company entered into a factoring agreement with an unrelated third party, pursuant to which the Company may sell certain of its accounts receivables for 86.25 % of the value of the receivable. Advances available under the facility are capped at the lesser of $ 3.0 million or a formula amount, as defined in the agreement. Interest on advances is assessed at a fixed amount upon funding, which is equivalent to an annualized rate of 15.0 % for the first 30 days, and daily thereafter at an annualized rate of 14.4 %. The agreement’s term is one month and automatically renews for additional one-month periods, unless either party provides 30 days’ notice of termination. The accounts receivable is sold with recourse back to the Company, therefore, the Company accounts for the arrangement as traditional financing. F-12 Table of Contents (In thousands) December 31, 2023 December 31, 2022 Receivables transferred $ 1,794 $ 2,564 Reserve amount held ( 304 ) ( 434 ) Factoring liability $ 1,490 $ 2,130 10. Senior Secured Debt, in Default The following table summarizes outstanding senior secured debt: December 31, 2023 December 31, 2022 (In thousands) Principal Debt Discount Carrying Value Principal Debt Discount Carrying Value Senior secured debt $ 21,562 $ ( 3,284 ) $ 18,278 $ 19,211 $ ( 4,795 ) $ 14,416 Senior secured promissory note payable, in default (“Senior Secured Note”) – In August 2020, the Company entered into a Note and Warrant Purchase and Security Agreement (the “NWPSA”). In accordance with the NWPSA, the Company issued a $ 15 million Senior Secured Promissory Note Payable (the “Senior Secured Note”) and a warrant exercisable into shares of the Company’s common stock in exchange for cash to support operations, repay outstanding debt and close on the acquisition of the UltraMIST assets from Celularity Inc. (Celularity) among other transactions. In February 2022, the Company entered into a Second Amendment to Note and Warrant Purchase and Security Agreement (the “Second NWPSA”) for $ 3.0 million, for a total of $ 18.0 million outstanding. Along with the issuance of the note, the Company also issued warrants to purchase 16.2 million shares of common stock with an exercise price of $ 0.18 and 20.6 million shares of common stock. Since the combined fair value of the warrants and common stock issued as part of the Second NWPSA exceeded the face value of the note, the additional amount beyond the face value was recorded as a loss on issuance totaling $ 3.4 million. Interest is charged at the greater of the prime rate or 3 % plus 9 %, paid quarterly . The principal increases at a rate of 3 % of the outstanding principal balance (PIK interest) on each quarterly interest payment date. The original maturity date of the Senior Secured Note is September 20, 2025, and it can be prepaid. In June 2022, the Company entered into the Third Amendment to the Note and Warrant Purchase and Security Agreement (the “Third NWPSA”). The Third NWPSA provides for (i) the extension of the agent’s and holder’s forbearance of exercising its remedies arising from Existing Defaults (as defined in the NWPSA) to the earlier of (x) the occurrence of an Event of Default (as defined in the NWPSA) or (y) August 30, 2022, and (ii) the extension to file a registration statement with the Securities and Exchange Commission to register the resale of the Advisor Shares (as defined in the NWPSA) no later than August 30, 2022. In June 2023, the Company entered into a Fourth Amendment to the NWPSA, which provides the Company an extension of the holder forbearing from exercising the remedies arising from the existing defaults to the earlier of the occurrence of an event of default and December 31, 2023. The amendment also added a consent fee of 2 % of the original principal amount of the NWPSA, payable in cash at maturity, accounted for as additional debt issuance costs. The amendment also defers interest that would otherwise have been due on June 30, 2023, and September 30, 2023. The interest will instead be compounded and added to the principal amount of the notes and bear interest at a rate of 20.25 % per annum. The amendment also requires the Company to complete an equity financing that results in gross cash proceeds of at least $ 2.5 million by July 15, 2023. This financing successfully closed on July 21, 2023. In March 2024, the Company entered into a Consent, Limited Waiver and Fifth Amendment to Note and Warrant Purchase Agreement (the “Fifth Amendment”). The Fifth Amendment provides (i) consent to enter into a License and Option Agreement and consummation of the License and Option Transaction (as disclosed in Note 22) (ii) a waiver of any event of default that may occur under the NWPSA, because of the License and Option Agreement or License and Option Transaction and (iii) amended the NWPSA to release certain patents from the collateral. The Fifth Amendment also provides for a forbearance of exercising remedies in connection with certain existing events of default under the NWPSA until the earlier of (x) the occurrence of another event of default under the NWPSA and (y) April 30, 2024. During the forbearance period, the outstanding obligations under the NWPSA continue to accrue interest at the default rate. As of December 31, 2023, the Company is in default on the minimum liquidity provisions in the Senior Secured Note and, as a result, it is classified in current liabilities in the accompanying consolidated balance sheets. The Company is accruing interest at the default interest rate of an incremental 5 %. F-13 Table of Contents The debt issuance costs, and debt discount related to the Senior Secured Note were capitalized as a reduction in the principal amount and are being amortized to interest expense over the life of the Senior Secured Note. Accrued interest related to the Senior Secured Note was $ 3.2 million and $ 1.9 million on December 31, 2023, and December 31, 2022, respectively. Interest expense on the Senior Secured Note totaled $ 6.9 million and $ 5.9 million for the years ended December 31, 2023, and 2022, respectively. 11.

Interest expense for the years ended December 31, 2023 and 2022, totaled $ 6.4 million and $ 4.4 million, respectively. Pursuant to the Notes, the Company promised to pay in cash and/or in shares of common stock, at a conversion price of $ 0.04 (the “Conversion Price”), the principal amount and interest at a rate of 15 % per annum on any outstanding principal. The Conversion Price of the Notes is subject to adjustment, including if the Company issues or sells shares of common stock for a price per share less than the Conversion Price of the Notes or if the Company lists its shares of common stock on The Nasdaq Capital Market and the average volume weighted average price of such common stock for the five trading days preceding such listing is less than $ 0.04 per share; provided, however, that the Conversion Price shall never by less than $ 0.01 . The Notes contain customary events of default and covenants, including limitations on incurrences of indebtedness and liens. In August 2023 and November 2023, the Company utilized its election to convert the August and November issued 2022 Convertible Notes Payable into shares of common stock upon the Notes’ maturity. The August notes totaling $ 16.2 million in principal and $ 2.4 million in interest were converted to 464,440,813 shares of common stock. The November notes totaling $ 4.0 million in principal and $ 0.6 million in interest were converted to 114,481,063 shares of common stock. Acquisition Convertible promissory notes payable - In August 2020, the Company entered into an asset purchase agreement with Celularity to acquire Celularity’s UltraMIST assets. A portion of the aggregate consideration of $ 24 million paid for the assets included the issuance of a promissory note to Celularity in the principal amount of $ 4 million (the “Seller Note”). The Seller Note matured on August 6, 2021 , and was not repaid. The Company’s failure to pay the outstanding principal balance when due constituted an event of default under the terms of the Seller Note and, accordingly, it began accruing additional interest of 5.0 % in addition to the 12.0 % initial rate, as of the date of the default. As of December 31, 2023, and 2022, the Seller Notes had outstanding accrued interest of $ 2.2 million and $ 1.5 million , respectively. The Company evaluated embedded conversion features within the convertible promissory note and determined that the conversion feature does not require to be bifurcated. Upon adoption of ASC 2020-06 effective January 1, 2021, the convertible promissory note is accounted for as a single liability due to the elimination of the beneficial conversion feature accounting model. F-14 Table of Contents Convertible promissory notes payable, related party - In August 2020, the Company issued a convertible promissory note payable in the amount of $ 1.4 million. The note matured on August 6, 2021 , and was not repaid and is currently in default. As of December 31, 2023, and 2022, the note had outstanding accrued interest of $ 636 thousand and $ 444 thousand, respectively. In October 2023, the Company signed a settlement letter agreement for the payment of $ 1.4 million principal to settle this convertible note. Payment is due on the earlier of March 31, 2024, or the closing of the Merger described in Note 4. If the Company fails to make payment, the lender retains all rights with respect to the convertible promissory note. 12. Asset-Backed Secured Promissory Notes In July 2023, the Company issued Asset-Backed Secured Promissory Notes (the “ABS Promissory Notes”) in an aggregate principal amount of $ 4.6 million to certain accredited investors (the “Purchasers”) at an original issue discount of 33.33 %. The ABS Promissory Notes bear an interest rate of 0 % per annum and mature on January 21, 2024 (the “Maturity Date”). The Company received total proceeds of approximately $ 3.0 million. The Company entered into a Security Agreement providing for a continuing and unconditional security interest in any and all property of the Company. This security interest is subordinate to the Senior Secured Debt described in Note 10. Interest expense for the year ended December 31, 2023, totaled $ 812 thousand. The Company and the Purchasers also entered into a side letter pursuant to which the parties agreed that upon the Maturity Date, or upon a fundamental transaction as defined by the ABS Promissory Notes, the Company will issue each Purchaser a Future Advance Convertible Promissory Note with the same principal amount as the principal amount of such Purchasers’ ABS Promissory Notes, plus any accrued and unpaid interest and two Common Stock Purchase Warrants, substantially in the forms of the Notes and Common Stock Purchase Warrants disclosed in Note 11. In evaluating the accounting for the ABS Promissory Notes and Side Letter (the “Side Letter”), pursuant to relevant guidance, the Side Letter was determined to not represent a freestanding financial instrument as it is not legally detachable and separately exercisable. The redemption features under the Side Letter are considered embedded derivatives, including a right for contingent redemption upon an event of default, automatic redemption upon maturity of the ABS Promissory Notes, and redemption is triggered upon a fundamental transaction. As a result, the Company determined these features met the criteria of an embedded derivative. December 31, 2023 (In thousands) Principal Debt Discount Embedded Derivative Carrying Value ABS promissory notes $ 3,122 $ ( 53 ) $ 48 $ 3,117 ABS promissory notes, related parties 1,462 ( 49 ) 45 1,458 Total ABS Promissory Notes $ 4,584 $ ( 102 ) $ 93 $ 4,575 13. Fair Value Measurements The Company uses various inputs to measure the outstanding warrants and certain embedded conversion features associated with convertible debt on a recurring basis to determine the fair value of the liabilities. The following table classifies the Company’s liabilities measured at fair value on a recurring basis into the fair value hierarchy: Fair value measurement at December 31, 2023 (in thousands) Fair value Quoted prices in active markets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Warrant liability $ 14,447 - - $ 14,447 Conversion option 93 - - 93 Total Fair Value $ 14,540 $ - $ - $ 14,540 F-15 Table of Contents Fair value measurement at December 31, 2022 (in thousands) Fair value Quoted prices in active markets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Warrant liability $ 1,416 - - $ 1,416 Conversion option 2,340 - - 2,340 Total Fair Value $ 3,756 $ - $ - $ 3,756 There were no transfers between Level 1, 2, or 3, during the years ended December 31, 2023, and 2022. Both observable and unobservable inputs were used to determine fair value of the positions that the Company classified within the Level 3 category. Unrealized gains and losses associated with the liabilities within the Level 3 category include changes in fair value that were attributable to both observable and unobservable inputs. Warrant Liability The Company’s liability classified warrants as of December 31, 2023, and initial valuation of December 2023 warrants, were valued using a probability weighted expected value considering the Merger Agreement and the previous Black Scholes valuation model, with significant value stemming from the Merger Agreement. Significant inputs under the Merger Agreement valuation included the risk adjusted expected exchange ratio ( 0.003 ), the value of SEPA’s Class A Common Stock, the expected timing of the closing of the Merger (estimated by February 29, 2024), and the probability of the Merger closing ( 90 % probability). Significant Black Scholes valuation model inputs related to the Company’s warrants are listed below: Initial Valuation May 2023 Issuance December 31, 2022 Weighted average expected life in years 5.00 4.68 Weighted average volatility 84 % 92 % Value of underlying shares $ 0.019 $ 0.005 Weighted average risk free interest rate 3.50 % 4.00 % Expected dividend yield - - A summary of the Level 3 warrant activity is as follows: (in thousands, except per share data) Warrants Outstanding Fair Value per Share Warrant Liability Fair Value Balance December 31, 2021 62,617 $ 0.15 $ 9,614 Cashless exercise ( 27,037 ) 0.09 ( 3,130 ) Issuance of warrants classified as liablities 1,031,276 0.06 4,873 Change in fair value - - ( 9,941 ) Balance December 31, 2022 1,066,856 $ 0.06 $ 1,416 Warrants exercised - - - Issuance of warrants classified as liablities 154,452 0.01 1,655 Change in fair value - - 11,376 Balance December 31, 2023 1,221,308 $ 0.01 $ 14,447 Embedded Conversion Option Certain convertible notes include a conversion option that meets the definition of a derivative liability and, accordingly, is required to be bifurcated. The fair value for the embedded derivative liability at issuance for the ABS Promissory Notes was estimated as the difference in fair value of the ABS Promissory Notes, including the conversion obligation under the Side Letter and the value of the ABS Promissory Notes in the absence of the conversion obligation. The value of the ABS Promissory Notes without the conversion obligation was estimated using a discounted cash flow analysis with an estimated market yield. F-16 Table of Contents The Company’s embedded conversion liability for the initial valuation of the December 2023 financing, and as of December 31, 2023, was valued using a probability weighted expected value considering the Merger Agreement and the previous Black Scholes model, with significant value being assigned to the Merger Agreement assumptions. Significant inputs included the risk adjusted expected exchange ratio ( 0.003 ), value of SEPA class A common stock, expected timing of the closing of the merger (estimated by February 29, 2024), and probability of the merger transaction closing ( 90 % probability). The fair value of conversion option liability assumptions for initial valuation of May 2023, and December 31, 2022, under the Black Scholes model are listed below: Initial Valuation May 2023 Issuance December 31, 2022 Conversion price (1) $ 0.04 $ 0.04 Value of underlying shares $ 0.019 $ 0.005 Interest Rate (annual) (2) 4.70 % 4.64 % Volatility (annual) (3) 114 % 503 % Time to maturity 1.00 0.60 (1) Based on the terms provided in the convertible promissory note agreements to convert to common stock of the Company (2) Interest rate for U.S. Treasury Bonds, as of each presented period ending date, as published by the U.S. Federal Reserve. (3) Based on the historical daily volatility of the Company as of each presented period ending date. As of December 31, 2022, the Company applied a discount rate to the historical volatility. A summary of the conversion option liability activity is as follows: (in thousands) Conversion Liability Balance December 31, 2021 $ 6,255 Issuance of Convertible Notes 2,760 Settlement of convertible notes ( 218 ) Change in fair value ( 6,457 ) Balance December 31, 2022 $ 2,340 Issuance of Convertible Notes ( 519 ) Change in fair value ( 1,728 ) Balance December 31, 2023 $ 93 14. Contract Liabilities The Company has contract liabilities from contracts with customers as follows: During the years ended December 31, 2023, and 2022, the Company recognized revenue related to these contract liabilities of $ 60 thousand and $ 253 thousand, respectively, that were included in the beginning contract liability balances for each of those periods. The following table summarizes the changes in contract liabilities: Year Ended December 31, (in thousands) 2023 2022 Beginning balance $ 290 $ 341 New service agreements 209 202 Revenue recognized ( 60 ) ( 253 ) Total Contract Liabilities $ 439 $ 290 F-17 Table of Contents 15.

Common Stock In December 2022, the Company’s stockholders approved an amendment to the Company’s Articles of Incorporation to increase the number of authorized shares of common stock from 800,000,000 to 2,500,000,000 . In January 2023, the Company filed the amendment to the Articles of Incorporation with the state of Nevada to affect the increase in authorized shares. 17. Concentration of Credit Risk and Limited Suppliers Major customers are defined as customers whose accounts receivable, or sales individually consist of more than ten percent of total trade receivable or total sales, respectively. There were no accounts receivable concentrations on December 31, 2023, or 2022. The Company currently purchases most of its product component materials from single suppliers and the loss of any of these suppliers could result in a disruption in our production. The percentage of purchases from major vendors of the Company that exceeded ten percent of total purchases were as follows: Year ended December 31, 2023 2022 Purchases: Vendor A 19 % 19 % Vendor B 19 % 0 % 18. Revenue The disaggregation of revenue is based on type and geographical region.

Stock-Based Compensation On November 1, 2010, the Company approved the Amended and Restated 2006 Stock Incentive Plan of SANUWAVE Health, Inc. effective as of January 1, 2010 (the “Stock Incentive Plan”). The Stock Incentive Plan permits grants of awards to selected employees, directors, and advisors of the Company in the form of restricted stock or options to purchase shares of common stock. Options granted may include non-statutory options as well as qualified incentive stock options. The Stock Incentive Plan is administered by the board of directors of the Company. The Stock Incentive Plan gives broad powers to the board of directors of the Company to administer and interpret the form and conditions of each option. The stock options granted under the Stock Incentive Plan are generally non-statutory options which generally vest over a period of up to three years and have a ten-year term. The options are granted at an exercise price determined by the board of directors of the Company to be the fair market value of the common stock on the date of the grant. As of December 31, 2023, and 2022, the Stock Incentive Plan reserved a total of 35,000,000 shares of common stock for grant. On December 31, 2023, there were 5,598,216 shares of common stock available for grant under the Stock Incentive Plan. 20. Income Taxes The Company files income tax returns in the United States Federal jurisdiction and various state and foreign jurisdictions. The Company is subject to United States Federal and state income tax examinations by tax authorities for any years that have net operating losses open until the net operating losses are used. The components of the net loss before income taxes are as follows: Year ended December 31, (In thousands) 2023 2022 Domestic $ ( 25,783 ) $ ( 10,279 ) Foreign ( 20 ) ( 12 ) Net loss before income taxes $ ( 25,803 ) $ ( 10,291 ) In accordance with ASC Topic 740, Income Taxes (“ASC 740”), the Company accounts for income taxes utilizing the asset and liability method. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is provided for the deferred tax assets, including loss carryforwards, when it is more likely than not that some portion or all a deferred tax asset will not be realized. The income tax provision (benefit) from continuing operations consists of the following: (In thousands) December 31, 2023 December 31, 2022 Current: Federal $ - $ - State 4 2 Foreign - - Current Tax Provision $ 4 $ 2 Deferred: Federal $ ( 3,564 ) $ ( 5,657 ) State ( 459 ) 753 Foreign ( 3 ) ( 1 ) Change in valuation allowance 4,026 4,905 Deferred Tax Provision $ - $ - As of December 31, 2023, and 2022, the Company did no t have any undistributed earnings of our foreign subsidiaries. As a result, no additional income or withholding taxes have been provided for. The Company does not anticipate any impacts of the global intangible low taxed income (“GILTI”) and base erosion anti-abuse tax (“BEAT”) and as such, the Company has not recorded any impact associated with either GILTI or BEAT. F-19 Table of Contents The income tax provision (benefit) amounts differ from the amounts computed by applying the United States Federal statutory income tax rate of 21 % for the years ended December 31, 2023, and 2022. Adjustments to determine income tax expense are as follow: (In thousands) Years ended December 31, 2023 2022 Tax benefit at statutory rate $ ( 5,485 ) $ ( 2,161 ) Increase (reduction) in income taxes resulting from: State income tax benefits, net of federal benefit ( 307 ) ( 473 ) Non-deductible gain on warrant adjustment valuation 2,102 ( 3,270 ) Change in valuation allowance 4,026 4,905 Registration penalties - 67 Other ( 332 ) 934 Income Tax Expense $ 4 $ 2 F-20 Table of Contents The tax effects of temporary differences that give rise to the deferred tax assets are as follows: (In thousands) December 31, 2023 December 31, 2022 Deferred Tax Assets Net operating loss carryforwards $ 42,484 $ 38,323 Net operating loss carryforwards - foreign 27 24 Excess of tax basis over book value of property and equipment 70 9 Excess of tax basis over book value of intangible assets 1,162 1,325 Lease liability 192 150 Stock-based compensation 1,495 1,487 Accrued employee compensation 338 750 Capitalized equity costs 235 - Capitalized research and development 1,273 116 Net change in reserve accounts - 1,031 Gross deferred tax asset 47,276 43,215 Valuation Allowance ( 47,096 ) ( 43,070 ) Net Deferred Tax Asset 180 145 Deferred Tax Liabilities Right-of-use asset ( 180 ) ( 145 ) Gross deferred tax liability ( 180 ) ( 145 ) TOTAL $ - $ - On August 16, 2022, the U.S. government enacted the Inflation Reduction Act of 2022 (the “Inflation Reduction Act”) into law. The Inflation Reduction Act imposes an excise tax of 1% on the fair market value of net stock repurchases made after December 31, 2022. The impact of this provision will be dependent on the extent of share repurchases made in future periods. We continue to analyze the impacts of the Inflation Reduction Act; however, it is not expected to have a material impact on our financial statements. Additionally, the Inflation Reduction Act includes a new corporate alternative minimum tax which is not currently applicable to the Company. The Tax Cuts and Jobs Act (“TCJA”) requires taxpayers to capitalize and amortize research and development (“R&D”) expenditures under section 174 for tax years beginning after December 31, 2021. This rule became effective for the Company during 2022 and resulted in capitalized R&D costs of $ 1.3 million as of December 31, 2023. The Company will amortize these costs for tax purposes over five years for R&D performed in the U.S. and over 15 years for R&D performed outside the U.S. In 2023, all R&D was performed in the U.S. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. In assessing the realization of deferred tax assets, management considers, whether it is “more likely than not”, that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. ASC 740 requires that a valuation allowance be established when it is “more likely than not” that all, or a portion of, deferred tax assets will not be realized. A review of all available positive and negative evidence needs to be considered, including the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies. After consideration of all the information available, management believes that uncertainty exists with respect to future realization of its deferred tax assets and has, therefore, established a full valuation allowance as of December 31, 2023, and 2022. F-21 Table of Contents The Company’s ability to use its net operating loss carryforwards could be limited and subject to annual limitations. Since a full analysis under Section 382 of the Internal Revenue Code has not been performed, the Company may realize a “more than 50% change in ownership” which could limit its ability to use its net operating loss carryforwards accumulated to date to reduce future taxable income and tax liabilities. Additionally, because United States tax laws limit the time during which net operating loss carryforwards may be applied against future taxable income and tax liabilities, the Company may not be able to take advantage of all or portions of its net operating loss carryforwards for Federal income tax purposes. The Federal net operating loss carryforwards of approximately $ 77.9 million from years ending December 31, 2005, through December 31, 2017, will begin to expire in 2025 . The Federal net operating loss carryforward for the years ended December 31, 2018, through 2023 of approximately $ 99.9 million will not expire. The state net operating loss carryforwards of approximately $ 75.1 million from years ending December 31, 2005, through December 31, 2023, will expire at various dates through 2043 . The foreign net operating loss carryforward on December 31, 2023, of $ 0.1 million will begin to expire in 2024 . A provision of ASC 740 specifies that companies are to account for uncertainties in income tax reporting, and prescribes a methodology for recognizing, reversing, and measuring the tax benefits of a tax position taken, or expected to be taken, in a tax return. ASC 740 requires the evaluation of tax positions taken or expected to be taken while preparing the Company’s tax returns to determine whether the tax positions would “more-likely-than-not” be sustained if challenged by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Management has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s consolidated financial statements as of December 31, 2023, and 2022. The Company does not expect any significant changes in the unrecognized tax benefits within twelve months of the reporting date. The Company will recognize in income tax expense, interest and penalties related to income tax matters. For the years ended December 31, 2023, and 2022, the Company did no t have any amounts recorded for interest and penalties. 21. Commitments and Contingencies Litigation In the ordinary course of business, the Company from time to time becomes involved in various legal proceedings involving a variety of matters. The Company does not believe there are any pending legal proceedings that will have a material adverse effect on the Company’s business, consolidated financial position, results of operations, or cash flows. However, the outcome of such legal matters is inherently unpredictable and subject to significant uncertainties. The Companies expenses legal fees in the period in which they are occurred. In February 2024, the Company entered into a termination agreement with an advisor to agree on termination fees owed with respect to a previous engagement agreement. The company agreed to a contingent payment of $670 thousand upon the closure of the Merger disclosed in note 4. Acquisition Dispute In May 2022, the Company received notification alleging that it is not in compliance with the license agreement with Celularity entered in connection with the acquisition of the UltraMIST assets.

CONTROLS AND PROCEDURES Evaluation of Disclosure Controls and Procedures We maintain disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. We carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer and accounting officer), of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2023. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not operating effectively as of December 31, 2023. Management’s Annual Report on Internal Control over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) for the Company. The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance of achieving their control objectives. Management, with the participation of the Chief Executive Officer (principal executive officer) and the Chief Financial Officer (principal financial and accounting officer), evaluated the effectiveness of the Company’s internal control over financial reporting as of December 31, 2023. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control — Integrated Framework (2013). As of December 31, 2023, the Company identified the following material weaknesses: 1. Expertise and resources to analyze and properly apply U.S. GAAP to complex and non-routine transactions such as complex financial instruments and derivatives and complex sales distributing agreements with select vendors. 2. A lack of internal resources to analyze and properly apply U.S. GAAP to accounting for financial instruments included in service agreements with select vendors. 3. The Company has failed to design and implement controls around all accounting and IT processes and procedures and, as such, we believe that all its accounting and IT processes and procedures need to be re-designed and tested for operating effectiveness. As a result, management concluded that its internal control over financial reporting was not effective as of December 31, 2023. 39 Table of Contents Remediation Plan We are working with an external vendor to properly document our current internal control policies and procedures to provide the framework for increased effectiveness to test internal controls going forward. We are also adding automated and manual controls into and over the Company’s enterprise resource planning (“ERP”) system to ensure that controls are implemented to mitigate the risk in customer creation, pricing, and accuracy of billing. We will continue to work with our external vendor to remediate the weaknesses noted above. We are also working with an outside vendor to improve our IT general controls over our ERP system and set up a proper framework for IT general controls to be executed with the objective to remediate the weaknesses regarding internal controls and provide the framework for testing going forward. While the above actions and planned actions are subject to ongoing management evaluation and will require validation and testing of the design and operating effectiveness of internal control over a sustained period, we are committed to continuous improvement and will continue to diligently review our internal control over financial reporting. The material weaknesses will not be considered remediated until management completes the design and implementation of the measures described above, until the controls operate for a sufficient period of time, and until management has concluded, through testing, that the controls are effective. There is no assurance that the measures described above will be sufficient to remediate the previously identified material weaknesses and significant deficiencies. Changes in Internal Control over Financial Reporting There have been no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2023, that materially affect, or are reasonably likely to materially affect, our internal control over financial reporting, except as disclosed above. Item 9B. OTHER INFORMATION During the three months ended December 31, 2023, none of our directors or officers (as defined in Rule 16a-1(f) of the Exchange Act) adopted or terminated any contract, instruction, or written plan for the purchase or sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) of the Exchange Act or any non-Rule 10b5-1 trading arrangement (as defined in Item 408(c) of Regulation S-K) Item 9C.

Since 2004, Mr. Richardson served as managing partner of Prides Capital LLC, an investment management firm, until its liquidation in September 2015 CORPORATE GOVERNANCE AND BOARD MATTERS The Board of Directors The Company’s current board of directors consists of six members, four of whom have been determined by the board to be “independent” as defined under the rules of the OTC stock market. The board of directors has determined that Messrs. Frank and Richardson are not independent under the applicable marketplace rules of the OTC stock market. During 2023, the Board held seven meetings. Each incumbent director attended at least 75% of the aggregate of the total number of meetings of the Board held during the period for which he has been a director and the total number of meetings held by all committees of the Board on which he served during the periods that he or she served. Board’s Leadership Structure The Company’s board of directors elects the Company’s chief executive officer and its chairman, and each of these positions may be held by the same person or may be held by two persons. The chairman’s primary responsibilities are to manage the board and serve as the primary liaison between the board of directors and the chief executive officer, while the primary responsibility of the chief executive officer is to manage the day-to-day affairs of the Company, considering the policies and directions of the board of directors. Such an arrangement promotes more open and robust communication among the board and provides an efficient decision-making process with proper independent oversight. The Company’s board of directors, as of May 2023, with the appointment of Morgan Frank as Chief Executive Officer,, determined that it is currently in the best interest of the Company and its shareholders to combine the roles of chairman of the board and chief executive officer. The Company believes, however, that there is no single leadership structure that is always the best and most effective in all circumstances. Accordingly, the board of directors retains the authority to later separate these roles if doing so would be in the best interests of the Company and its shareholders. The Company’s board of directors is authorized to have an audit committee, a compensation committee, and a nominating and corporate governance committee, to assist the Company’s board of directors in discharging its responsibilities. 42 Table of Contents Board’s Role in Risk Oversight While the Company’s management is responsible for the day-to-day management of risk to the Company, the board of directors has broad oversight responsibility for the Company’s risk management programs. The various committees of the board of directors assist the board of directors in fulfilling its oversight responsibilities in certain areas of risk. In particular, the audit committee focuses on financial and enterprise risk exposures, including internal controls, and discusses with management and the Company’s independent registered public accountants the Company’s policies with respect to risk assessment and risk management. The compensation committee is responsible for considering those risks that may be implicated by the Company’s compensation programs and reviews those risks with the Company’s board of directors and chief executive officer. Audit Committee The audit committee operates under a written charter adopted by the board of directors which is available on the Company’s website at www.sanuwave.com . The primary responsibility of the audit committee is to oversee the Company’s financial reporting process on behalf of the board of directors.

Among other things, the audit committee is also responsible for reviewing with management the effectiveness of the Company’s internal controls and disclosure controls and procedures.

The primary purpose of the compensation committee is to discharge the responsibilities of the board of directors relating to compensation of the Company’s executive officers. Pursuant to the Company’s Compensation Committee Charter, the compensation committee is required to consist of at least two independent directors. The compensation committee operates under a written charter adopted by the board of directors which is available on the Company’s website at www.sanuwave.com . Specific responsibilities of the compensation committee include reviewing and recommending approval of compensation of the Company’s named executive officers, administering the Company’s stock incentive plan, and reviewing and making recommendations to the Company’s board of directors with respect to incentive compensation and equity plans.

Stockholders who wish to communicate directly with the board of directors or any director should deliver any such communications in writing to the Secretary of the Company. The Secretary will compile any communications they receive from stockholders and deliver them periodically to the board of directors or the specific directors requested. The Secretary of the Company will not screen or edit such communications but will deliver them in the form received from the stockholder. Code of Conduct and Ethics It is the Company’s policy to conduct its affairs in accordance with all applicable laws, rules and regulations of the jurisdictions in which it does business. The Company has adopted a code of business conduct and ethics with policies and procedures that apply to all associates (all employees are encompassed by this term, including associates who are officers) and directors, including the chief executive officer, chief financial officer, controller, and persons performing similar functions. The Company has made the code of business conduct and ethics available on its website at www.sanuwave.com . If any substantive amendments to the code of business conduct and ethics are made or any waivers are granted, including any implicit waiver, the Company will disclose the nature of such amendment or waiver on its website or in a Current Report on Form 8-K. No Family Relationships Among Directors and Officers There are no family relationships between any director or executive officer of the Company and any other director or executive officer of the Company. Limitation of Directors Liability and Indemnification The Nevada Revised Statutes authorize corporations to limit or eliminate, subject to certain conditions, the personal liability of directors to corporations and their stockholders for monetary damages for breach of their fiduciary duties. Our certificate of incorporation limits the liability of our directors to the fullest extent permitted by Nevada law. We have director and officer liability insurance to cover liabilities our directors and officers may incur in connection with their services to us, including matters arising under the Securities Act of 1933, as amended. Our certificate of incorporation and bylaws also provide that we will indemnify our directors and officers who, by reason of the fact that he or she is one of our officers or directors, is involved in a legal proceeding of any nature. There is no pending litigation or proceeding involving any of our directors, officers, employees, or agents in which indemnification will be required or permitted. We are not aware of any threatened litigation or proceeding that may result in a claim for such indemnification. DELINQUENT SECTION 16(a) REPORTS Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who own more than 10% of our equity securities which are registered pursuant to Section 12 of the Exchange Act, to file with the SEC initial reports of ownership and reports of changes in ownership of our equity securities. Except as set forth herein, based solely upon a review of the Forms 3, 4 and 5 (and amendments thereto) furnished to us for our fiscal year ended December 31, 2023, we have determined that our directors, officers and greater than 10% beneficial owners complied with all applicable Section 16 filing requirements.

Base salaries and benefits packages are fixed components of our NEO’s compensation and do not vary with Company performance. Short term Cash Incentives The performance-based compensation plan reflects our pay-for-performance philosophy and directly ties short-term incentives to short-term business performance. These awards are linked to specific annual financial goals and key business initiatives for the overall Company. Annual employee bonus incentives are paid to reward the achievement of critical short-term operating, financial, and strategic goals. The annual employee bonus is calculated based on a percentage of the each NEO’s salary, 50% is paid on individual performance goals, as assigned by leadership and the Board of Directors, and the remainder is paid based on Company performance measures. Stock Incentive Plan On October 24, 2006, SANUWAVE, Inc.’s board of directors adopted the 2006 Stock Incentive Plan of SANUWAVE, Inc. (the “2006 Plan”). On November 1, 2010, the Company approved the Amended and Restated 2006 Stock Incentive Plan of SANUWAVE Health, Inc. effective as of January 1, 2010 (previously defined as the “Stock Incentive Plan”). The Stock Incentive Plan permits grants of awards to selected employees, directors, and advisors of the Company in the form of restricted stock or options to purchase shares of common stock. Options granted may include non-statutory options as well as qualified incentive stock options. The Stock Incentive Plan is administered by the board of directors of the Company. The Stock Incentive Plan gives broad powers to the board of directors of the Company to administer and interpret the form and conditions of each option. The stock options granted under the Stock Incentive Plan are non-statutory options which vest over a period of up to three years and have a maximum ten-year term. The options are granted at an exercise price equal to the fair market value of the common stock on the date of the grant. The terms of the options granted under the Stock Incentive Plan expire as determined by individual option agreements (or on the tenth anniversary of the grant date), unless terminated earlier, on the first to occur of the following: (1) the date on which the participant’s service with the Company is terminated by the Company for cause; (2) 60 days after the participant’s death; or (3) 60 days after the termination of the participant’s service with the Company for any reason other than cause or the participant’s death; provided that, if during any part of such 60 day period the option is not exercisable solely because of specified securities law restrictions, the option will not expire until the earlier of the expiration date or until it has been exercisable for an aggregate period of 60 days after the termination of the participant’s service with the Company. The options vest as provided for in each option agreement and the exercise prices for the options are determined by the board of directors at the time the option is granted, provided that the exercise price shall in no event be less than the fair market value per share of the Company’s common stock on the grant date. In the event of any change in the common stock underlying the options, by reason of any merger or exchange of shares of common stock, the board of directors shall make such substitution or adjustment as it deems to be equitable to (1) the class and number of shares underlying such option, (2) the exercise price applicable to such option, or (3) any other affected terms of such option. 45 Table of Contents In the event of a change of control, unless specifically modified by an individual option agreement: (1) all options outstanding as of the date of such change of control will become fully vested; and (2) notwithstanding (1) above, in the event of a merger or share exchange, the board of directors may, in its sole discretion, determine that any or all options granted pursuant to the Stock Incentive Plan will not vest on an accelerated basis if the board of directors, the surviving corporation or the acquiring corporation, as the case may be, has taken such action that in the opinion of the board of directors is equitable or appropriate to protect the rights and interests of the participants under the Stock Incentive Plan. No equity awards were issued during the years ended December 31, 2023, and 2022. Transition and Separation Agreement with Mr. Richardson On May 23, 2023, SANUWAVE and Mr. Richardson entered into a Transition and Separation Agreement (the “Transition Agreement”), pursuant to which Mr. Richardson agreed to serve as SANUWAVE’s Chief Strategy Officer for an anticipated period of 12 months or alternatively a consulting agreement for a period of two years.
