PART I

ITEM 1. BUSINESS

History

Zynex Inc. was founded by Thomas Sandgaard in 1996, when he founded smaller private companies that eventually were folded into Zynex, Inc.  Zynex Inc., a Nevada corporation,  that was formed in December 2001, is the parent company of and conducts business within six subsidiaries: Zynex Medical, Inc. (“ZMI”), a Colorado corporation, Zynex Neurodiagnostics, Inc. (“ZND”), a Colorado corporation, Zynex Monitoring Solutions, Inc. (“ZMS”), a Colorado corporation, Zynex Billing and Consulting, LLC (“ZBC”), a Colorado limited liability company, Zynex Europe (Zynex Europe ApS) (“ZEU”), a Danish corporation, and Pharmazy, Inc. (“Pharmazy”), which was incorporated under the laws of Colorado in June 2015 as a wholly-owned subsidiary of ZMI collectively referred to as “Zynex” or the “Company”.

As of December 31, 2017, the Company’s only active subsidiary is Zynex Medical, Inc. (“ZMI,” a wholly-owned Colorado corporation) through which the Company conducts most of its operations. One other subsidiary, Zynex Europe, ApS (“ZEU,” a wholly-owned Denmark corporation), generated minimal revenues during the years ended December 31, 2017 and 2016 from international sales and marketing. Zynex Monitoring Solutions, Inc. (“ZMS,” a wholly-owned Colorado corporation) has developed a blood volume monitoring device which is in the process of approval by the Food and Drug Administration (“FDA”) in the United States of American and CE Marking in Europe. As a result, ZMS has achieved no revenues to date. Its inactive subsidiaries include Zynex NeuroDiagnostics, Inc. (“ZND,” a wholly-owned Colorado corporation), Zynex Billing and Consulting, LLC (“ZBC,” an 80% owned Colorado limited liability company) and Pharmazy, Inc. (“Pharmazy”), which was incorporated in June 2015 as a wholly-owned Colorado corporation. The Company’s compound pharmacy operated as a division of ZMI dba as Pharmazy through January 2016.

Over 99% of total 2016 and 2017 consolidated revenue is attributable to ZMI. Our headquarters are located in Englewood, Colorado.

Overview

Zynex Medical, Inc. (ZMI):

ZMI designs, manufactures and markets medical devices that treat chronic and acute pain, as well as activate and exercise muscles for rehabilitative purposes with electrical stimulation. ZMIThe Company’s devices are intended for pain management to reduce reliance on drugs and medications and provide rehabilitation and increased mobility through the utilization of non-invasive muscle stimulation, electromyography technology, interferential current (“IFC”), neuromuscular electrical stimulation (“NMES”), and transcutaneous electrical nerve stimulation (“TENS”). All of our medical devices are intendeddesigned to be patient friendly and designed for home use. The ZMIOur devices are small, portable, battery operated, and include an electrical pulse generator which is connected to the body via electrodes. The products are cost effective when compared to traditional physical therapy, and often result in better mobility, less pain and increased potential for a patient to return to work and live a fuller life significantly earlier than with traditional therapies alone. All of our medical devices are marketed in the U.S. and are subject to US Food and Drug Administration (FDA)FDA regulation and approval.clearance. Our products require a physician’s prescription before they can be dispensed in the U.S. We consider the physician’s prescription as an “order”, and it is on this basis that we provide the product to the patient and either bill the patient directly or the patient’s private or government insurer for payment. ZMI’sOur primary product is the NexWave device. The NexWave is marketed to physicians and therapists by our field sales representatives. The NexWave requires consumable supplies, such as electrodes and batteries, which are shipped to patients, on a recurring monthly basis, as needed.

ZMI alsodistributes complementary rehabilitation products such as back, knee and wrist braces, cervical and lumbar traction, and hot/cold therapy (“Distributed Rehabilitation Products”). These complement our pain management products and are critical for physicians and therapists. These products require a prescription and are covered by most insurance plans and Medicare.

ZMI designs, manufactures, and markets the NeuroMove product. The NeuroMove contains electromyography and electric stimulation technology that is primarily used for stroke, spinal cord and traumatic brain injury rehabilitation (“SCI”), by reaching parts of the brain to re-connect with muscles, also known as neuroplasticity. The NeuroMove product is primarily marketed to medical clinics. Zynex did not have material sales of this product in 20162023 or 2017.2022.

ZMI also designs, manufactures, and markets the InWave product, an in-home electrical stimulation device used to treat female urinary incontinence. The device requires a prescription and is covered by most insurance plans and Medicare. Zynex did not have material sales of this product in 2023 or 2022.

ZMI designs, manufactures and markets the E-Wave product. The E-Wave is a user-friendly NMES device designed for muscle stimulation and re-education. E-Wave is a fully programmable, compact, battery-powered device with adjustable treatment timer, compliance meter, biphasic or monophasic waveforms, and exceptional safety features. The E-Wave is marketed to physicians and therapists and requires consumable supplies, electrodes and batteries, for use. On October 25, 2023, Zynex Medical, Inc. dba Pharmazy (ZMI)submitted FDA application for M-Wave, the next generation E-Wave device. The M-Wave will offer a more modern design and Pharmazy, Inc (Pharmazy):enhanced ease of use with the same versatility as the E-Wave. As of March 12, 2024, the Company does not anticipate a material financial impact of the M-Wave on the Company’s consolidated financial statements. 

In 2012,  many industry sales representatives, including those representing Zynex, began offering prescription TransDermal Pain Creams (TDPC) to their accounts, a product that paid much higher commissions with less paperwork than TENS devices.  TDPC, like TENS, offers very effective, non-addictive pain management with minimal side effects. In late 2013, Zynex opened a compound pharmacy to enter the prescription TransDermal Pain Cream (“TDPC”) market. The new pharmacy operated within ZMI, (ZMI dba “Pharmazy”) and obtained its first state license in February 2014. In June 2015, we incorporated Pharmazy, Inc. in Colorado as a wholly owned subsidiary of ZMI. During January 2016, we shut down our compound pharmacy business.  The business struggled due to the unfavorably changing pharmacy insurance reimbursements. In addition, we focused on our core electrotherapy product business and our potential and future blood volume monitor business described for ZMS, below.

Zynex Monitoring Solutions (ZMS):

ZMS was formed in 2011 to develop and market medical devices for non-invasive cardiac monitoring. During 2015, ZMS was still in development and did not have any revenue.patient monitoring beginning with our Zynex Fluid Monitoring System. The blood volume monitor is a non-invasive medical device for monitoring central bloodrelative fluid volume that would bechanges used in operating and recovery rooms to detect bloodfluid loss during surgery and internal bleeding during recovery. This deviceThe CM-1500 received 510(k) clearance from the FDA in February 2020 and the wireless CM-1600 received clearance in June 2023.

The Zynex Fluid Monitoring System has been subjected to multipletested in several Institutional Review Board (“IRB”) approved clinical studies, both in well-controlled healthy volunteer settings as well as in clinical use environments. In 2022 and 2023, the clinical trials were expanded to include the next generation CM-1600. Enrollment was completed in an apheresis blood donation study with Vitalant Research Institute (the research arm of Vitalant, the nation’s largest independent, nonprofit blood services provider) to track changes in the device’s patented Relative Index (“RI”) during platelet apheresis procedures. A healthy volunteer study was also completed at Yale University Medical School where subjects underwent lower body negative pressure, a well-validated protocol for simulated hemorrhage while wearing the device. Enrollment was initiated in a large-scale multi-site study to measure the sensitivity and specificity of the

Finally, a non-cardiac surgery perioperative observational study to determine changesthe impact of complex perioperative events on the parameters and RI measured by the CM-1600 was completed in central blood volume and planning for future, additional clinical studies. May 2023.

We have submittedbuilt a 510(k)number of commercial devices in pilot-production and continue to refine the algorithms for the patented Relative Index. We have received two U.S. utility patents for this unique application, the first in the fourth quarter of 2018 and the second in the first quarter of 2021, and we believe this product could serve a currently unmet need in the market for safer surgeries and safer monitoring of patients during recovery.

In addition to the FDA and are respondingclearance, we plan to their questions. There is no guarantee when or if the product will be cleared for marketing by the FDA.

Concurrent to our FDA application, we are pursuingpursue European Union (“EU”) Certificate European (“CE”) Marking. CE Marking is a certification that a product meets the standards established by the 2827 nations of the EU and qualifies for sale in the EU and 4-nation European Free Trade Association.

In early 2022, the integration of Kestrel and its pulse oximetry products into the ZMS organization was completed. Pulse oximetry is a commonly used noninvasive monitoring method for estimation of oxygen saturation in arterial blood. The inaccuracies of traditional Light Emitting Diode (“LED”) based pulse oximeters have recently been highlighted specific to skin pigmentation bias and the inability to accurately measure blood volume monitor has been testedoxygen levels in several Internationalthe presence of other conditions such as in cases of carbon monoxide poisoning or methemoglobinemia. ZMS’ investigational laser-based products are designed to address these inaccuracies and include the novel NiCO™ CO-Oximeter, and HemeOx™, a total hemoglobin oximeter that is designed to enable continuous noninvasive arterial blood monitoring. NiCO is anticipated to be submitted to the FDA for clearance in the first half of 2024. NiCO is currently undergoing Institutional Review Board (“IRB”) approved clinical studies on human subjects to measure hypoxemia. Enrollments at the University of California San Francisco were completed in May 2023 and during 2015, was usedenrollments at Duke University are ongoing.

As ZMS’ products are still in several blood donation settings where hundreds of subjects have donated half a liter of blood with strong correlation to the index on the device. We have built a number of commercial devices in pilot-production and continue to refine the algorithms for the Blood Volume Index (BVI). Two utility patents have been filed for this unique application (pending), which we believe could serve a currently unmet need in the market for safer surgeries and safer monitoring of patients during recovery.development, ZMS did not produce any revenue for the years ending December 31, 20172023 and 2016.  2022.

In addition to the fluid volume monitor, ZMS filed for a provisional patent for a non-invasive sepsis monitor in December 2020 and an updated utility patent, which was filed in December 2021.

Zynex International (Zynex Europe) (ZEU):History

ZEU was formed in 2012 to further progress Zynex’s international expansion. ZEU is currently conducting business and focused on sales and marketing our products within the international marketplace, upon receipt of necessary regulatory approvals. ZEU did not produce significant revenue for the years ended December 31, 2017 and 2016.

Zynex NeuroDiagnostics (ZND):

ZND was formed in 2011 to market electromyography (“EMG”), electroencephalography (“EEG”), sleep pattern, auditory and nerve conductivity neurological diagnosis devices to hospitals and clinics worldwide, through the utilization of existing ZMI diagnostic EMG technology.  ZND has not generated revenue for years ended December 31, 2017 and 2016 and we are no longer actively pursuing sales of this product line.

Zynex Billing and Consulting (ZBC):

During the latter part of 2012, we established a medical billing and consulting subsidiary, ZBC. ZBC provided outsourced billing services for private medical practices, which include collection services, medical coding and general billing consulting. ZBC is majority owned by Zynex, Inc. (80%)was founded by Thomas Sandgaard in 1996, when he founded two privately held companies that were eventually folded into Zynex, Inc., a Nevada corporation. Zynex, Inc. is the parent company of two active subsidiaries; Zynex Medical, Inc. (“ZMI,” a wholly-owned Colorado corporation) and hasZynex Monitoring Solutions, Inc.

SALES AND GROWTH STRATEGIES

To date, ZMI accounts for substantially all of our revenue and profit. We are focused on expanding our sales force to address what we believe is an untapped market for electrotherapy products for pain management which has become more attractive due to large competitors exiting the years endedmarket. As of December 31, 20172023, we had approximately 500 field sales representatives on staff or in the hiring process. We continue to hire field sales representatives at a rapid rate, focusing on the quality of each candidate with the goal of having approximately 600 sales representatives in the U.S. by the end of 2024. We will be focused on increasing performance management standards for our sales force.

In an effort to increase revenue and 2016.  diversification, we provide our prescribers and patients with diverse solutions for their pain management needs. We are continually adding new complementary products to our ZMI sales channel, in addition to our current Distributed Products. We believe adding these complementary products will increase our market share and, in the future, grow our core business by providing our electrotherapy patients additional non-pharmacological pain relief and complementary products to our manufactured devices.

Distribution and Revenue Streams:

Substantially all our revenue is generated through our ZMI subsidiary from our electrotherapy products.

ProductsWe sell through a direct sales force in the United States. Our field sales representatives are engaged to sell in predefined geographic markets and are compensated with a base salary plus incentive compensation aligned to corporate objectives based on the type of product sold and insurance. Our efforts to date have been focused on the United States market.

Our revenue is derived from several sources including patients with insurance plans held by commercial health insurance carriers or government payers who pay on behalf of their insureds. The remaining portion of revenue is primarily received from workers’ compensation claims, auto claims, attorneys representing injured patients, hospitals, clinics, and private-pay individuals.

We currently marketA large part of our revenue is recurring. Recurring revenue results primarily from the sale of surface electrodes and sell Zynex-manufacturedbatteries sent to existing patients with our devices. Electrodes and batteries are consumable items that are considered an integral part of our products.

Distributed Rehabilitation Products

In addition to our own products, we offer our suite of Distributed Rehabilitation Products, through our sales force, a number of private labeled supplies and complementary products from other manufacturers. Customarily, there are no formal contracts between vendors in the durable medical equipment industry.

Product Uses

Pain Management and Control

Standard electrotherapy is a clinically proven and medically accepted alternative to manage acute and chronic pain. Electrical stimulation has been shown to reduce most types of local pain, such as tennis elbow, neck or lower back pain, arthritis, and others. The devices used to accomplish this are commonly described as the TENS family of devices. Electrotherapy is not known to have any negative side effects, a significant advantage over most pain relief medications. The benefits of electrotherapy can include:include pain relief, increased blood flow, reduced edema, prevention of venous thrombosis, increased range-of-motion, prevention of muscle disuse atrophy, and reduced urinary incontinence.

Electrotherapy introduces an electrical current applied through surface electrodes. The electrical current “distorts” a pain signal on its way to the central nervous system and the brain, thus reducing the pain. Additionally, by applying higher levels of electricity, muscles contract and such contraction mayis believed to assist in the effectsbenefits mentioned above.

Numerous clinical studies have been published over several decades showing the effectiveness of IFC and TENS for pain relief. Zynex’sOur primary TENSelectrotherapy device, the NexWave, has received FDA 510(k) clearance. The NexWave is a digital IFC, TENS and NMES device that delivers pain-alleviating electrotherapy.

Stroke and Spinal Cord Injury (“SCI”) Rehabilitation

Our proprietary NeuroMove product is a Class II medical device that has been cleared by the FDA for stroke and SCI rehabilitation. Stroke and SCI usually affect a survivor’s mobility, functionality, speech, and memory, and the NeuroMove helpsis designed to help the survivor regain movement and functionality.

The NeuroMove product utilizes the relatively new science of “neuroplasticity”, the process by which healthy parts of the brain learn to compensate and assume functions previously carried out by the damaged areas. To accomplish this task, the extraordinarily sensitive NeuroMove technology monitors muscle activity and detects brain signals that indicate, even without any visible movement, the brain’s effort to move a specific muscle or area of the body. Once the effort is detected, the NeuroMove induces actual movement through electrical stimulation, thus providing effective feedback to initiate relearning in the healthy part of the brain.

We believe the NeuroMove product is unique because its built-in microprocessor can recognize low-level attempts by muscles to contract and then “reward” such detection with electrical stimulation. We do not believe there are similar products in the stroke rehabilitation market. Some generic devices are being offered in international markets; however, we do not believe these products provide similar results with respect to stroke rehabilitation. When conscientiously using the NeuroMove product for three to twelve months, studies show that the majority of NeuroMove patients can re-establish the connection between the brain and impaired muscle and thus regain movement and functionality.When movement and functionality are restored, the patient may experience increased mobility, increased productivity, an improved outlook, and a reduced risk of accidents, and may be able to engage in activities they were precluded from before using the NeuroMove. Sales of NeuroMove havedid not generatedgenerate material revenue for the years ended December 31, 20172023 and 2016.

Fluid Monitoring

Fluid monitoring involves measuring a patient’s fluid balance, especially regarding fluid inputs and outputs contributing to total intravascular volume. Adequate fluid balance is vital for patient stability and recovery, as both low and high volumes outside of the desired range are associated with complications. Maintaining effective circulating blood volume and pressure are key to assuring adequate oxygen saturation and perfusion.

Monitoring methods used for hemodynamic and intravascular volume monitoring have been historically classified as (a) invasive, using a central or pulmonary artery catheter, (b) minimally invasive, with the placement of an arterial line, and (c) noninvasive, where no device is inserted into the body for clinical assessment.

The Zynex Fluid Monitoring System CM-1500 and the Zynex Wireless Fluid Monitoring System CM-1600 are noninvasive monitoring devices designed to measure relative changes in fluid volume in adult patients. Fluid status is determined using Zynex’s proprietary algorithm and expressed as the patented Relative Index™, a simple value designed to accurately trend patient vital signs and alert clinicians for early intervention.

The CM-1500 was cleared by the FDA in 2020, and the wireless CM-1600 was cleared in June 2023 by the FDA.

Pulse Oximetry Monitoring

Pulse oximetry is a noninvasive method of measuring the oxygen saturation level (“SpO2”) of arterial blood. As one of the most common medical devices used in and out of hospitals around the world, pulse oximeters have gained widespread clinical acceptance as the standard of care for monitoring oxygen saturation. SpO2 has become the “fifth vital sign”, which, together with heart rate, blood pressure, respiratory rate, and temperature, provides crucial clinical information about a person’s health status.

The NiCO™ Noninvasive CO-Oximeter, the first laser-based photoplethysmographic patient monitoring technology, is designed to noninvasively measure and monitor four crucial species of hemoglobin with unprecedented accuracy.

The HemeOx™ Total Hemoglobin Pulse Oximeter is designed to noninvasively measure total hemoglobin and oxygen saturation, two critical parameters that typically require invasive arterial blood sampling for measurement. Total hemoglobin is a very commonly ordered blood test in healthcare, and HemeOx™ measures it with the continuous and noninvasive ease of a pulse oximeter at the patient bedside.

The NiCO™ Noninvasive CO-Oximeter and the HemeOx™ Total Hemoglobin Pulse Oximeter have not yet been cleared by the FDA.

In the market segments in which we compete, we face a mixture of competitors ranging from large manufacturers with multiple business lines to small manufacturers that offer a limited selection of products. The primary competitor in our market is International Rehabilitative Sciences, Inc. d/b/a RS Medical. In addition, we face competition from providers of alternative medical therapies, such as pharmaceutical companies.

The majority of our revenue is generated by the sale of medical devices and from recurring patient supplies specifically from our electrotherapy products sold through ZMI. We are reliant on insurancethird-party payer reimbursement.

Zynex Monitoring Solutions (ZMS):

ZMS is focused on developing products within the non-invasive multi-parameter patient-monitoring marketplace. ZMS is currently focusing on developing its blood volume monitor.fluid monitoring system, the sepsis monitor, and the pulse oximetry products acquired in its acquisition of Kestrel Labs. We believe our product,products, once released into the marketplace (of which there can be no guarantee), will compete against multiple competitors, ranging from large manufacturers with multiple business lines to small manufacturers that offer a limited range of products. We have not yet identified competitors for this product. ZMS has not generated any revenue as this product is stillto date.

Zynex NeuroDiagnostics (ZND):

ZND is focused on developing products within the neurosensing marketplace in an effort to diversify our concentration of ZMI electrotherapy revenue. There were no significant revenues during 2017 or 2016 in ZND.

Sales and Growth Strategies

To date, ZMI accounts for substantially all of our revenue and profit. We are currently focused on expanding our sales force to address what we believe is an untapped market for medical electrotherapy products, which has recently become more attractive duewe face a mixture of competitors ranging from large manufacturers with multiple business lines to largesmall manufacturers that offer a limited selection of products.

We believe these events and actions will serve to focus and increase our market share in the electrotherapy market and, in the future, diversify our product mix. We also continue to modify and refine our geographic sales channels through experienced sales representatives, representing a mix of Zynex employees, sales contractors and international distributors. As of December 31, 2017 we had approximately101 active field sales representatives. An insignificant amount of our revenue is derived from international sales; however we continue to take steps to penetrate the global medical device marketplace.companies.

RESOURCES

Manufacturing and Product Assembly

Our manufacturing and product assembly strategy consists of the following elements:

Compliance with relevant legal and regulatory requirements.
Use of contract manufacturers as much as possible,needed, thereby allowing us to quickly respond to changes in volume and avoid large capital investments for assembly and manufacturing equipment. Domestically and internationally,equipment of certain product components. We believe there is a large pool of highly qualified contract manufacturers, domestically and internationally, for the type of devices we manufacture.manufacturing assistance needed for our manufactured devices.
Utilization of in-house final assembly and test capabilities.
Development of proprietary software and hardware for all products in house.in-house.
Testing all units in a real-life, in-house environment to help ensure the highest possible quality and patient safety while reducing the cost of warranty repairs.

We utilize contract manufacturers (principally located in the United States)U.S. to manufacture components for our NexWave and NeuroMove units and for some of our other products;products and manufacture / assemble in-house for our NexWave and NeuroMove units. We do not have long termlong-term supply agreements with our contract manufacturers, but we utilize purchase orders with agreed upon terms for our ongoing needs. We believe there are numerous suppliers that can manufacture our products and provide our required raw materials. Generally, we have been able to obtain adequate supplies of our required raw materials and components. We are always evaluating our suppliers for price, quality, delivery time, and service. The reduction or interruption in supply, and an inability to develop alternative sources for such supply, could adversely affect our operations.

During 2016 and the first half of 2017, our inventory levels, which is driven by product assembly, was constrained by liquidity issues. Due to improved operating results in 2016 and 2017, we believe our liquidity constraints have been removed and we are in the process of building our inventory reserves to meet current sales demands. 

Distribution and Revenue Streams:

Currently, almost all of our revenue is generated through our ZMI subsidiary from our electrotherapy products.

We sell most of our medical devices through direct and independent sales representatives in the United States. Our field sales representatives are engaged to sell in predefined geographic markets and are compensated based on the amount of cash collected from products sold. Currently, the United States has been the market that we have focused on; however, we have established international distributors in Canada, Australia, Russia, China, India, Singapore, Holland, Germany, the United Arab Emirates (UAE), Malaysia, Saudi Arabia, Egypt and Viet Nam. Typically, we sell and ship product directly to our international distributors, who work directly with the ultimate patient or end-user. To date these international customers have not generated significant revenue.

A significant portion of our revenue is derived from patients with private health insurance carriers with insurance plans, typically known as HMO or PPO, on behalf of their insureds as well as worker’s compensation agencies. The balance of the revenue is primarily received from attorneys representing injured patients, hospitals, clinics and private-pay individuals. We no longer accept Medicare and Medicaid orders.

A large part of our revenue is recurring. Recurring revenue results primarily from the sale of surface electrodes and batteries sent to existing patients on our units. Electrodes and batteries are consumable items that are considered an integral part of our products.

Private Labeled Distributed Products

In addition to our own products, we distribute, through our sales force, a number of private labeled products from other domestic manufacturers in order to complement our products. These products generally include patient consumables, such as electrodes and batteries plus cervical traction, lumbar support and hot/cold therapy. Customarily, there are no formal contracts between vendors in the durable medical equipment industry. Replacement products and components are easily found, either from our own products or other manufacturers, and purchases are made by purchase order.

Intellectual Property

Although we do not own any patents, we believe thatZynex is committed to aggressively protecting the intellectual property rights the Company has worked so hard to obtain and to expand our products contain certain proprietary software. We currently have applied for utility patents for products related to cardiac monitoring within ZMS in both US and Europe. In the future, we may seek patentsintellectual property portfolio for advances to our existing products and for new products as they are developed. During 2017

Zynex has received two U.S. utility patents, as well as a utility patent in Europe, for our fluid monitoring system. The acquisition of Kestrel Labs, Inc. included an intellectual property portfolio surrounding the acquired laser-based photoplethysmographic technology. This expands both the size and 2016, we incurred approximately $0.1 millionscope of Zynex’s intellectual property portfolio to include key aspects of the exciting pulse oximetry market. Additional patents for photoplethysmographic technology were filed in 2022 and $0.3 million, respectively, of research2023. Zynex also received issued trademarks for NiCO™ and development expenses. We expect our research and development expenditures will be limited throughout 2018.

GOVERNMENT REGULATION

Regulatory ApprovalUS Food and Process

Federal Drug AssociationAdministration (FDA)

All of our ZMI products are classified as Class II (Medium Risk) devices by the FDA, and clinical studies with our products are considered to be NSR (Non-SignificantNon-Significant Risk Studies)Studies (“NSR”). Our business is regulated by the FDA, and all products typically require 510(k) market clearance before they can be put ininto commercial distribution. Section 510(k) of the Federal Food, Drug and CosmeticsCosmetic Act, is available in certain instances for Class II (Medium Risk) products.devices. It requires that, before introducing most Class II devices into interstate commerce, our introducing the productsponsor must first submit information to the FDA demonstrating that the device is substantially equivalent in terms of safety and effectiveness to a device legally marketed prior to March 1976 or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act that do not require approval of a premarket approval application. When the FDA determines that the device is substantially equivalent, the agency issues a “clearance” letter that authorizes marketing of the product. We are also regulated by the FDA’s GMP and QSR (Quality Systems Regulation).Quality System Regulation (“QSR”), which sets forth current Good Manufacturing Practice (“GMP”) requirements for devices. We believe that our products have obtained or are good candidates for the requisite FDA clearance or are exempt from the FDA clearance process. In November 2001, Zynex received FDA 510(k) clearance to market NeuroMove. In September 2011, Zynex received FDA 510(k) clearance to market the NexWave, our current generation IFC, TENS and NMES device. In August 2012, Zynex received FDA 510(k) clearance to market the InWave, our next generation muscle stimulator for treatment of female incontinence. Failure to comply with FDA requirements could adversely affect us.

In 2019, Zynex has received ISO13485: 20122016 certification for its compliance with international standards in quality management systems for design, development, manufacturing, and distribution of medical devices. This certification is not only important as an assurance that we have the appropriate quality systems in place but is also crucial to our international expansion efforts as many countries require this certification as part of their regulatory approval. The quality management system is audited on an annual basis and current recertification is pending final audit review.

Government Regulation

The delivery of health care services and products has become one of the most highly regulated of professional and business endeavors in the United States. Both the federal government and individual state governments are responsible for overseeing the activities of individuals and businesses engaged in the delivery of health care services and products. Federal law and regulations are based primarily upon the Medicare and Medicaid programs. Each program is financed, at least in part, with federal funds. State jurisdiction is based upon the state’s interest in regulating the quality of health care in the state, regardless of the source of payment. Many state and local jurisdictions impose additional legal and regulatory requirements on our business including various states and local licenses, taxes, limitations regarding insurance claim submission and limitations on relationships with referral parties. Failure to comply with this myriad of regulations in a particular jurisdiction may subject us to fines or other penalties, including the inability to sell our products in certain jurisdictions.

Federal health carehealthcare laws apply to us when we submit a claim to any other federally funded health carehealthcare program, in addition to requirements to meet government standards. The principal federal laws that we must abide by in these situations include:

Those that prohibit the filing of false or improper claims for federal payment.
Those that prohibit unlawful inducements for the referral of business reimbursable under federally funded health carehealthcare programs.

The federal government may impose criminal, civil, and administrative penalties on anyone who files a false claim for reimbursement from federally funded programs.

A federal law commonly known as the “anti-kickback law” prohibits the knowing or willful solicitation, receipt, offer, or payment of any remuneration made in return for:

The referral of patients covered under federally-funded health carefederally funded healthcare programs; or
The purchasing, leasing, ordering, or arranging for any goods, facility, items, or service reimbursable under those programs.

Healthcare Regulation

EmployeesFederal and state healthcare laws, including fraud and abuse and health information privacy and security laws, also apply to our business. If we fail to comply with those laws, we could face substantial penalties and our business, results of operations, financial condition, and prospects could be adversely affected. The laws that may affect our ability to operate include but are not limited to: the federal Anti-Kickback Statute, which prohibits, among other things, soliciting, receiving, offering, or paying remuneration, directly or indirectly, to induce, or in return for, the purchase or recommendation of an item or service reimbursable under a federal healthcare program, such as the Medicare and Medicaid programs; and federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payers that are false or fraudulent. Additionally, we are subject to state law equivalents of each of the above federal laws, which may be broader in scope and apply regardless of whether the payer is a federal healthcare program, and many of which differ from each other in significant ways and may not have the same effect, further complicate compliance efforts.

Numerous federal and state laws, including state security breach notification laws, state health information privacy laws, and federal and state consumer protection laws, govern the collection, use, and disclosure of personal information. In addition, most healthcare providers who are expected to prescribe our products and from whom we obtain patient health information are subject to privacy and security requirements under the Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology and Clinical Health Act (“HIPAA”). We could be subject to criminal penalties if we knowingly obtain individually

9

identifiable health information from a HIPAA-covered entity, including healthcare providers, in a manner that is not authorized or permitted by HIPAA. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing amount of focus on privacy and data protection issues with the potential to affect our business, including recently enacted laws in a majority of states requiring security breach notification. These laws could create liability for us or increase our cost of doing business.

In addition, the Physician Payments Sunshine Act, enacted as part of the Patient Protection and Affordable Care Act of 2010 (“ACA”), created a federal requirement under the federal Open Payments program that requires certain manufacturers to track and report to the Centers for Medicare and Medicaid Services (“CMS”), annually certain payments and other transfers of value provided to physicians and certain advanced non-physician healthcare practitioners and teaching hospitals made in the previous calendar year, as well as ownership and investment interests held by physicians and their immediate family members. In addition, there are also an increasing number of state laws that require manufacturers to make reports to states on pricing and marketing information. These laws may affect our sales, marketing, and other promotional activities by imposing administrative and compliance burdens on us. In addition, given the lack of clarity with respect to these laws and their implementation, our reporting actions could be subject to the penalty provisions of the pertinent state and federal authorities.

Research and Development

Research and Development costs are expensed when incurred. During 2023 and 2022, we incurred approximately $9.2 million and $7.1 million in operating expenses, respectively, related to our ZMS operations. During 2023 and 2022, approximately $7.7 million and $6.0 million of operating expenses, respectively, required capitalization under Section 174 - “Amortization of Research and Experimental Expenditures” tax treatment. We expect our research and development expenses to increase in 2024 as our ZMS business expands.

HUMAN CAPITAL

ITEM 1A. RISK FACTORS

RISKS RELATED TO OUR BUSINESS AND THE INDUSTRY IN WHICH WE OPERATE

Unfavorable global economic conditions could adversely affect our business, financial condition, or results of operations.

We’ve encountered significant volatility in our recent operatingOur results

The Company’s results from of operations have improved significantly in recent years but there has been significant volatility in our results over the past 5 years as reflectedcould be adversely affected by general conditions in the following table (in thousands):global economy and in the global financial markets, including conditions that are outside of our control, such as the impact of health and safety concerns, including SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) (“COVID-19”) pandemic and various variants, as well as military conflicts or wars (such as the ongoing conflicts between Russia and Ukraine and Israel and Palestine) that can cause exacerbated volatility and disruptions to various aspects of the global economy, and other disruptions to global supply chains. Each of these events has caused or may continue to result in extreme volatility and disruptions in the capital and credit markets. A severe or prolonged economic downturn, whether due to inflationary pressures or otherwise, could result in a variety of risks to our business, including weakened demand for our products and our ability to raise additional capital when needed on acceptable terms, if at all. A weak or declining economy could strain our suppliers, possibly resulting in supply disruption, or cause delays in payments for our services by third-party payers or our collaborators. Any of the foregoing could harm our business, and we cannot anticipate all the ways in which the current economic climate and financial market conditions could adversely impact our business.

Year Revenues  Profit (Loss) 
2014 $11.1  $(6.2)
2015 $11.6  $(2.9)
2016 $13.3  $0.07 
2017 $23.4  $7.4 

A pandemic, epidemic, or outbreak of an infectious disease, such as of COVID-19 and subsequent variants, may materially and adversely affect our business and results of operations.

Our financial resultsPublic health crises such as pandemics or similar outbreaks could adversely impact our business. In 2019, COVID-19 surfaced in Wuhan, China and has since spread worldwide. The COVID-19 pandemic is evolving and to date has led to the implementation of various responses including government-imposed quarantines, travel restrictions, and other public health safety measures. The effects of this outbreak on our business have included and could continue to include temporary closures of our providers and clinics and suspensions of elective surgical procedures. This has and could continue to impact our interactions and relationships with our customers.

In addition to temporary closures of the providers and clinics that we serve, we could also experience temporary closures of the facilities of our suppliers, contract manufacturers, or other vendors in our supply chain, which could impact our business, interactions and relationships with our third-party suppliers and contractors, and results of operations. The extent to which COVID-19 will impact our future business and the economy will also depend on future developments, which are highly uncertain and cannot be volatilepredicted with confidence, including the duration of the pandemic, adverse impacts of the Omicron COVID-19 variant or other COVID-19 variants, new information that will emerge concerning the severity of COVID-19, and there isthe actions to contain COVID-19 or treat its impact, among others. Accordingly, we cannot predict the extent to which our financial condition, results of operations, and value of our common stock will be affected. The uncertainty surrounding the COVID-19 outbreak has caused the Company to increase its inventory in anticipation of possible supply chain shortages related to the COVID-19 virus. While we did not incur significant disruptions to our operations during 2023 and 2022, we are unable at this time to predict with confidence the impact that COVID-19 will have on our business, financial position, and operating results in future periods due to numerous uncertainties.

Rapid technological change could cause our products to become obsolete and if we do not enhance our product offerings through our research and development efforts, we may be unable to effectively compete.

The technologies underlying our products are subject to rapid and profound technological change. Competition intensifies as technical advances in each field are made and become more widely known. We can give no assurance that others will not develop services, products, or processes with significant advantages over the products, services, and processes that we offer or are seeking to develop. Any such occurrence could have a material and adverse effect on our business, results of operations, and financial condition.

We plan to enhance and broaden our product offerings in response to changing customer demands and competitive pressure and technologies, but we may not be successful. The success of any new product offering or enhancement to an existing product will continuedepend on numerous factors, including our current increase in revenue and profits.ability to:

Our history of operating losses and negative working capital may make it difficult to raise any new capital and may have an adverse impact on our relationship with third parties with whomIf we do business, includingnot develop and, when necessary, obtain regulatory clearance or approval for new products or product enhancements in time to meet market demand, or if there is insufficient demand for these products or enhancements, our customers, vendorsresults of operations will suffer. Our research and employees.  

We’ve had lack of liquidity in recent periods which led to a going concern opinion in prior years.

During 2013-2015, the Company suffered operating losses which caused a lack of liquidity anddevelopment efforts may require a substantial working capital deficit. This raised substantial doubt aboutinvestment of time and resources before we are adequately able to determine the Company’s abilitycommercial viability of a new product, technology, material, or other innovation. In addition, even if we are able to continuesuccessfully develop enhancements or new generations of our products, these enhancements or new generations of products may not be covered or reimbursed by government healthcare programs such as a going concern.Medicare or private health plans, may not produce sales in excess of the costs of development, and/or may be quickly rendered obsolete by changing customer preferences or the introduction by our competitors of products embodying new technologies or features.

During 2016, the Company generated net income during Q3 and Q4 and combined with the profitability in 2017, the Company has recorded six consecutive profitable quarters, paid off its line of credit with Triumph Healthcare Finance, a division of TBK Bank, SSB, formerly known as Triumph Community Bank, (“Triumph”) and generated cash reserves and positive working capital.

Our history of operating losses could make it difficult to raise any new capital and may have an adverse impact on our relationship with third parties with whom we do business, including our customers, vendors and employees.

We cannot be certain the Company won’t be impacted by liquidity challenges in the future due to the volatile operating results mentioned above.

We are dependent on reimbursement from insurance companies;third-party payers, most of whom are larger than we are and have substantially more employees and financial resources; changes in insurance reimbursement policies or application of them have resulted in decreased or delayed revenues

revenues.

A large percentage of our revenues come from third-party payer reimbursement. Most of the third-party payers are large insurance company and government health care program reimbursement.companies with substantially more resources than we have. Upon delivery of our products to our customers,patients, we directly bill the customers’patients’ private insurance companycompanies or government payorpayers for reimbursement. If the billed payorsthird-party payers do not pay their billsremit payment on a timely basis or if they change their policies to exclude or reduce coverage for our products, we would experience a decline in our revenue as well as cash flow. In addition, we may deliver products to customerspatients and invoice based on past practices and billing experiences with health insurance companies andonly to have a health insurance companythird-party payers later deny coverage for such products.

In some cases, our delivered product may not be covered pursuant to a policy statement of a health insurance provider,third-party payer, despite a payment history ofwith the insurance providerthird-party payer and benefits to the patients. A health insurance providerthird-party payer may seek repayment of amounts previously paid for covered products. We maintain an allowance for provider discounts forand amounts intended to cover legitimate requests for repayment. Failure to adequately identify and provide for amounts for resolution of repayment demands in our allowance for provider discounts could have a material adverse effect on our results of operations and cash flows. For government health carehealthcare programs, if we identify a deficiency in prior claims or practices, we may be required to repay amounts previously reimbursed to us by government health carehealthcare programs.

We frequently receive, and expect to continue to receive, refund requests from insurance providers relating to specific patients and dates of service. Billing and reimbursement disputes are very common in our industry. These requests are sometimes related to a few patients and other times include a significant number of refund claims in a single request.request which can accumulate to a significant amount. We review and evaluate these requests and determine if any refund is appropriate. We alsoDuring the adjudication process, we review claims where we are rebilling or pursuing additional reimbursement from that insurance provider. We frequently have significant offsets against such refund requests which may result in amounts that are due to us in excess of the amounts of refunds requested by the insurance providers. Therefore, at the time of receipt of such refund requests, we are generally unable to determine if a refund request is valid. Although we cannot predict whether or when a request for repayment or our subsequent request for reimbursement will be resolved, it is not unusual for such matters to be unresolved for a longan extended period of time. No assurances can be given with respect to our estimates for our allowance for provider discounts forrefund claim reimbursements and offsets or the ultimate outcome of the refund requests.

We are dependent on our Medicare Supplier Number.

DuringWe are required to have a Medicare Supplier Number in order to have the first quarterability to bill Medicare for services provided to Medicare patients. Furthermore, all third-party and Medicaid contracts require us to have a Medicare Supplier Number. We are required to

12

comply with Medicare Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (“DMEPOS”) Supplier Standards in order to maintain such number. If we are unable to comply with the Company collected $880,000 from a single insurance company for accounts receivable. The accounts receivable had been previously reducedrelevant standards, we could lose our Medicare Supplier Number. Without such number, we would be unable to zero by the allowance for billing adjustments. Subsequent to March 31, 2016, the insurance company verbally communicated to the Company that this payment was made in errorcontinue our various third-party and requested it be refunded to the insurance company. The Company recorded this $880,000 insurance reimbursement as a deferred insurance liability as of March 31, 2016. However, the Company is disputing the refund request and has initiated an internal review of the reimbursement to determine that the original sales arrangement was properly executed, the products had been received and title was transferred, the price of the products or services and the reimbursement rate is fixed and determinable, and the Company’s ultimate claim to the reimbursement is reasonably assured. The Company expects to record the appropriate amount as net revenue when such internal review is complete and the Company’s claim to the amount is reasonably assured. To the extent that the Company has to repay anyMedicaid contracts. A significant portion of our revenues are dependent upon our Medicare Supplier Number, the $880,000, this willloss of which would materially and adversely affect our business, financial condition, results of operations, and cash flows.

The Center for Medicare and Medicaid Services (“CMS”) requires that all Durable Medical Equipment providers must be accredited by a CMS-approved accreditation organization. On February 1, 2013, we initially received accreditation from the Accreditation Commission for Health Care (“ACHC”), and we have remained accredited to date. If we lost our accredited status, our business, financial condition, revenues, and results of operations would be materially and adversely affected.

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

As a result of our participation in the Medicaid program and our registration in the Medicare program, 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 CMS conduct extensive reviews of claims data and medical and other records to identify potential improper payments under the Medicare program. Private pay sources also reserve the right to conduct audits. If billing errors are identified in the sample of reviewed claims, the billing error can be extrapolated to all claims filed which could result in a larger overpayment than originally identified in the sample of reviewed claims. Our costs to respond to and defend reviews and audits may be significant and could have a negativematerial 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 payers;
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 payer 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.

Failure to secure and maintain adequate coverage and reimbursement from third-party payers could adversely affect acceptance of our products and reduce our revenues.

The majority of our revenues come from third-party payers, primarily insurance companies.

In the Company’s liquidity position.U.S., private payers cover the largest segment of the population, with the remainder either uninsured or covered by governmental payers. The majority of the third-party payers outside the U.S. are government agencies, government sponsored entities, or other payers operating under significant regulatory requirements from national or regional governments.

Third-party payers may decline to cover and reimburse certain procedures, supplies, or services. Additionally, some third-party payers may decline to cover and reimburse our products for a particular patient even if the payer has a favorable coverage policy addressing our products or previously approved reimbursement for our products. Furthermore, private and government payers may consider the cost of a treatment in approving coverage or in setting reimbursement for the treatment.

Private and government payers are increasingly challenging the prices charged for medical products and services. Additionally, the containment of healthcare costs has become a priority of governments. Adoption of additional price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures could further limit our revenues and operating results. If third-party payers do not consider our products or the combination of our products with additional

13

treatments to be cost-justified under a required cost-testing model, they may not cover our products for their populations or, if they do, the level of reimbursement may not be sufficient to allow us to sell our products on a profitable basis.

Reimbursement for the treatment of patients with medical devices is governed by complex mechanisms. These mechanisms vary widely among countries, can be informal, somewhat unpredictable, and evolve constantly, reflecting the efforts of these countries to reduce public spending on healthcare. As a result, obtaining and maintaining reimbursement for the treatment of patients with medical devices has become more challenging. We cannot guarantee that the use of our products will receive reimbursement approvals and cannot guarantee that our existing reimbursement approvals will be maintained in any country.

Our failure to secure or maintain adequate coverage or reimbursement for our products by third-party payers in the U.S. or in the other jurisdictions in which we market our products could have a material adverse effect on our business, revenues, and results of operations and cause our stock price to decline.

We may not be successful in maintaining the reimbursement codes necessary to facilitate accurate and timely billing for our products or physician services attendant to our products.

Third-party payers, healthcare systems, government agencies, or other groups often issue reimbursement codes to facilitate billing for products and physician services used in the delivery of healthcare. If we are unable to maintain the Healthcare Common Procedure Coding System codes (“HCPCS codes”) for physician services related to our products, our revenues and results may be affected by the absence of such HCPCS codes, as physicians may be less likely to prescribe the therapy when there is no certainty that adequate reimbursement will be available for the time, effort, skill, practice expense, and malpractice costs required to provide the therapy to patients.

Outside the United States, we have not secured codes to describe our products or to document physician services related to the delivery of therapy using our products. The failure to obtain and maintain these codes could affect the growth of our business.

We at times have concentrations of credit risk with third-party payers; failure to collect these and other billed receivables could adversely affect our cash flows and results of operations.

At December 31, 2023 the Company did not have gross receivables from any third-party payer which made up over 10% of the accounts receivable balance. The Company had gross receivables from one third-party payer at December 31, 2022, which made up approximately 14% of the accounts receivable balance.

Future changes in coverage and reimbursement policies for our products or reductions in reimbursement rates for our products by third party payorspayers could adversely affect our business and results of operations

operations.

In the United States, our products are prescribed by physicians for their patients. Based on the prescription, which we consider an order, we submit a claim for payment directly to third-party payorspayers such as private commercial insurance carriers, government payorspayers, and others as appropriate, and the payorthird-party payer reimburses us directly. Federal and state statutes, rules, or other regulatory measures that restrict coverage of our products or reimbursement rates could have an adverse effect on our ability to sell or rent our products or cause physical therapists and physicians to dispense and prescribe alternative, lower-cost products.

There are significant estimating risks associated with the amount of revenue, related refund liabilities, accounts receivable, and provider discounts that we recognize, and if we are unable to accurately estimate these amounts, it could impact the timing of our revenue recognition and cash collections, which have a significant impact on our operating results, or lead to a restatement of our financial results

results.

There are significant estimating risks associated with the estimation of the amount of revenues, related refund liabilities, accounts receivable, and provider discounts that we recognize in a reporting period. The billing and collection process is complex due to ongoing insurance coverage changes, geographic coverage differences, differing interpretations of coverage, differing provider discount rates, and other third party payorthird-party payer issues. Determining applicable primary and secondary coverage for our customers at any point in time, together with the changes in patient coverage that occur each month, requiresrequire complex, resource-intensive processes. Errors in determining the correct coordination of benefits may result in refunds to payors.payers. Revenues associated with government programs are also subject to estimating risk related to the amounts not paid by the primary government payorpayer that will ultimately be collectable from other

14

government programs paying secondary coverage, the patient’s commercial health plan secondary coverage or the patient. Collections, refunds, and pay or retractions typically continue to occur for up to three years and longer after our products are provided. While we typically look to our past experience in collections with a payorpayer in estimating ultimate amounts expected to be collected on current billings, nonetheless recent trends and current changes in reimbursement practice, the overall healthcare environment, and other factors nonetheless could ultimately impact the amount of revenues recorded and the receivables ultimately collected. If our estimates of revenues, related refund liabilities, accounts receivable, or provider discounts are materially inaccurate, it could impact the timing of our revenue recognition and have a significant impact on our operating results. It could also lead to a restatement of our financial results.

Tax laws and regulations require compliance efforts that can increase our cost of doing business. Changes to these laws and regulations could impact financial results.

12

In May 2014,We are subject to a variety of tax laws and regulations in the FASB issued ASU No. 2014-09—“Revenue from Contractsjurisdictions in which we do business. Maintaining compliance with Customers” (Topic 606) whichthese laws can increase our cost of doing business and failure to comply could result in audits or the imposition of fines or penalties. Further, our future effective tax rates in any of these jurisdictions could be affected, positively or negatively, by changing tax priorities, changes in statutory rates, or changes in tax laws or the interpretation thereof. The most significant recent example of this is effective for us January 1, 2018. We finalized our analysisthe impact of the new revenue guidance and we currently believe the adoption of this guidance will not have a material impact on our consolidated financial statements and our internal controls over financial reporting.

The Tax Cuts and Jobs Act could have material effects on the Company.

TheU.S Tax Cuts and Jobs Act of 2017 (“Tax(the “Tax Act”), which was signed into lawenacted on December 22, 2017, makes significant changes to the taxation of U.S. business entities.2017. These changes include a permanent reduction tosignificantly revised the ongoing U.S. corporate income tax law by lowering the U.S. federal corporate income tax rate from 35% to 21%, implementing a territorial tax system, imposing a one-time tax on foreign unremitted earnings, and setting limitations on deductibility of certain costs, among other things. The Company has implemented the Tax Act and does not expect any significant changes related to the Tax Act at this time.

The impact of healthcare reform legislation and other changes in the deductibilityhealthcare industry and in healthcare spending on us is currently unknown but may harm our business.

Our revenue is dependent on the healthcare industry and could be affected by changes in healthcare spending and policy. The healthcare industry is subject to changing political, regulatory, and other influences. The Patient Protection and Affordable Care Act (“PPACA”) made major changes in how healthcare is both delivered and reimbursed, and increased access to health insurance benefits to the uninsured and underinsured population of interestthe United States.

The PPACA, among other things, increased the number of individuals with Medicaid and private insurance coverage, implemented reimbursement policies that tie payment to quality, facilitated the creation of accountable care organizations that may use capitation and other alternative payment methodologies, strengthened enforcement of fraud and abuse laws, and encouraged the use of information technology. Such changes in the regulatory environment may also result in changes to our payer mix that may affect our operations and net revenue.

Certain provisions of the PPACA authorize voluntary demonstration projects, which include the development of bundling payments for acute, inpatient hospital services, physician services, and post-acute services for episodes of hospital care. Further, the PPACA may negatively impact payers by increasing medical costs generally, which could have an effect on corporate debt obligations, among others. Although we are evaluating the Tax Act withindustry and potentially impact our professional advisers, thebusiness and revenue as payers seek to offset these increases by reducing costs in other areas. The full impact of these changes on us cannot be determined at this time.

We are also impacted by the TaxMedicare Access and CHIP Reauthorization Act, under which physicians must choose to participate in one of two payment formulas, Merit-Based Incentive Payment System (“MIPS”) or Alternative Payment Models (“APMs”). Beginning in 2019, MIPS allows eligible physicians to receive upward or downward adjustments to their Medicare Part B payments based on certain quality and cost metrics, among other measures. As an alternative, physicians can choose to participate in an Advanced APM. Advanced APMs are exempt from the MIPS requirements, and physicians who are meaningful participants in APMs will receive bonus payments from Medicare pursuant to the law.

In addition, current and prior healthcare reform proposals have included the concept of creating a single payer or public option for health insurance. If enacted, these proposals could have an extensive impact on the healthcare industry, including us. We are unable predict whether such reforms may be enacted or their impact on our operations.

15

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments and other third-party payers will pay for healthcare services, which could harm our business, is currently uncertainfinancial condition, and results of operations.

The patient protectionPatient Protection and accountability actAffordable Care Act of 2010 has had an impact on our business which may be in part beneficial and in part detrimental

detrimental.

In March 2010, broad federal health carehealthcare reform legislation was enacted in the United States. This legislation did not become effective immediately in total and may be modified prior to the effective date of some provisions. This legislation has had an impact on our business in a variety of ways including increased number of Medicaid recipients, increased number of individuals with commercial insurance, additional audits conducted by public health insurance plans such as Medicaid and Medicare, changes to the rules that govern employer group health insurance, and other factors that influence the acquisition and use of health insurance from private and public payors.payers. This legislation has resulted in a change in reimbursement for certain durable medical equipment. We believe the new healthcare legislation and these changes to reimbursement have caused uncertainty with prescribers, which we believe contributed to our drop in orders and revenue during 2013 and 2014 and the lack of any significant increase in 2015. Orders and revenue increased in 2016 and 2017,through 2023; however, we are currently unable to determine whether such trend will continue in future periods or whether the health carehealthcare reform legislation will have other adverse consequences to our business and results of operations. To the extent prescribers write fewer prescriptions for our products or there is an adverse change to insurance reimbursement for our products, due to the new law or otherwise, our revenue and profitability will be materially adversely affected.

Effective 2013, there was a 2.3% excise tax on the first sale of medical devices, with certain exceptions. We believe that a majority of our ZMI products are not subject to this tax but currently we can make no assurance. For our products that are or become subject to this excise tax, we are uncertain of our ability to pass this tax on to third parties. Thus far this excise tax has not had a material impact on our financial results.

The uncertainty of continuing healthcare changes and regulations may placenegatively affect our business model in doubtbusiness.

As the popular press has made clear, thereThere is substantialsome doubt on the continuation of the Affordable Care Act and the legislation that the current Congress will enact to replace it, if any. There is also substantial doubt whether,Because we cannot be certain about the continuation of the Affordable Care Act or any changes or replacements thereto, even if the Affordable Care Act remains the law of the land, there is also some doubt whether the presidentPresident will support it or take regulatory action to negatively impact its benefits. This significantThe amount of uncertainty creates a significant concern on our customer’scustomers’ willingness to buy products which may or may not be covered by future health carehealthcare benefits even if they are covered currently.

We are subject, directly or indirectly, to United States federal and state healthcare fraud and abuse and false claims laws and regulations. Prosecutions under such laws have increased in recent years, and we may become subject to such litigation. If we are unable to or have not fully complied with such laws, we could face substantial penalties.

Our operations are subject to various state and federal fraud and abuse laws, including, without limitation, the federal Anti-Kickback Statute, the federal Stark Law, and the federal False Claims Act. These laws may impact, among other things, our sales, marketing, and education programs.

The federal Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, offering, receiving, or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual or the furnishing or arranging for a good or service, for which payment may be made under a federal healthcare program such as the Medicare and Medicaid programs. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statute has been violated. In addition, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. The Anti-Kickback Statute is broad and, despite a series of narrow safe harbors, prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry. Penalties for violations of the federal Anti-Kickback Statute include criminal penalties and civil sanctions such as fines, imprisonment, and possible exclusion from Medicare, Medicaid, and other federal healthcare programs. Many states have also adopted laws similar to the federal Anti-Kickback Statute, some of which apply to the referral of patients for healthcare items or services reimbursed by any source, not only the Medicare and Medicaid programs.

16

The federal Ethics in Patient Referrals Act of 1989, commonly known as the “Stark Law”, prohibits, subject to certain exceptions, physician referrals of Medicare and, as applicable under state law, Medicaid patients to an entity providing certain “designated health services” if the physician or an immediate family member has any financial relationship with the entity. The Stark Law also prohibits the entity receiving the referral from billing any good or service furnished pursuant to an unlawful referral. Various states have corollary laws to the Stark Law, including laws that require physicians to disclose any financial interest they may have with a healthcare provider to their patients when referring patients to that provider. Both the scope and exceptions for such laws vary from state to state. The federal False Claims Act prohibits persons from knowingly filing, or causing to be filed, a false claim to, or the knowing use of false statements to obtain payment from the federal government. The False Claims Act defines “knowingly” to include actual knowledge, acting in deliberate ignorance of the truth or falsity of information, or acting in deliberate disregard of the truth or falsity of information. False Claims Act liability includes liability for reverse false claims for avoiding or decreasing an obligation to pay or transmit money to the government. This includes False Claims Act liability for failing to report and return overpayments within 60 days of the date on which the overpayment is “identified”. Penalties under the False Claims Act can include exclusion from the Medicare program. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act. Suits filed under the False Claims Act, known as qui tam actions, can be brought by any individual on behalf of the government and such individuals, commonly known as “whistleblowers”, may share in any amounts paid by the entity to the government in fines or settlement. The frequency of filing qui tam actions has increased significantly in recent years, causing greater numbers of medical device, pharmaceutical, and healthcare companies to have to defend a False Claims Act action. When an entity is determined to have violated the federal False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties for each separate false claim. Various states have also enacted laws modeled after the federal False Claims Act.

HIPAA, and its implementing regulations, also created additional federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payer (e.g., public or private) and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items, or services relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

From time to time, the Company has been and is involved in various governmental audits, investigations, and reviews related to its operations. Reviews and investigations can lead to government actions, resulting in the assessment of damages, civil or criminal fines or penalties, or other sanctions, including restrictions or changes in the way we conduct business, loss of licensure, or exclusion from participation in Medicare, Medicaid, or other government programs. Additionally, as a result of these investigations, healthcare providers and entities may face litigation or have to agree to settlements that can include monetary penalties and onerous compliance and reporting requirements as part of a consent decree or corporate integrity agreement, or Corporate Integrity Agreement (“CIA”). If we fail to comply with applicable laws, regulations, and rules, the Company’s financial condition and results of operations could be adversely affected. Furthermore, becoming subject to these governmental investigations, audits, and reviews may result in substantial costs and divert management’s attention from the business as we cooperate with the government authorities, regardless of whether the particular investigation, audit, or review leads to the identification of underlying issues.

We are unable to predict whether we could be subject to actions under any of these laws, or the impact of such actions. If we are found to be in violation of any of the laws described above or other applicable state and federal fraud and abuse laws, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from Medicare, Medicaid, and other government healthcare reimbursement programs, and the curtailment or restructuring of operations.

Hospitals and clinicians may not buy, prescribe, or use our products in sufficient numbers, which could result in decreased revenues and profits

profits.

Hospitals and clinicians may not accept any of our products as effective, reliable, andor cost-effective. Factors that could prevent such institutional customerpatient acceptance include:

If customersif patients conclude that the costs of these products exceed the cost savings associated with the use of these products;
If customersif patients are financially unable to purchase these products;

17

Ifif adverse patient events occur with the use of these products, generating adverse publicity;
Ifif we lack adequate resources to provide sufficient education and training to our customers;patients;
Ifif frequent product malfunctions occur, leading clinicians to believe that the products are unreliable;
Uncertaintyuncertainty regarding or change in government or third party payorthird-party payer reimbursement policies for our products; and
Ifif physicians or other health care providers believe that our products will not be reimbursed by insurers or decide to prescribe competing products.

Because our sales are dependent on prescriptions from physicians, if any of these or other factors resultsresult in fewer prescriptions for our products being written, we will have reduced revenues and may not be able to fully fund our operations. Although we experienced an increase in orders for our ZMI products during 20162023 and 20172022 compared to prior years, we can make no assurances that demand for our products will not decline in future periods.

13

Any new competitor could be larger than us and have greater financial and other resources than we do, and those advantages could make it difficult for us to compete with them

them.

Many competitors to our products may have substantially greater financial, technical, marketing, and other resources. Competition could result in our need to reduce prices, result in fewer orders, reduced gross margins, and loss of market share. Our products are regulated by the FDA.FDA in the United States. Competitors may develop products that are substantially equivalent to our FDA clearedFDA-cleared products, thereby using our products as predicate devices to more quickly obtain FDA approval for their own.own products. If overall demand for our products should decrease, it could have a material adverse effect on our operating results. Substantial competition is expected in the future in the area of stroke rehabilitation that may directly compete with our NeuroMove product. These competitors may use standard or novel signal processing techniques to detect muscular movement and generate stimulation to such muscles. Other companies may develop rehabilitation products that perform better and/or are less expensive than our products, which could have a material adverse effect on our operating results.

Failure to keep pace with the latest technological changes could result in decreased revenues

revenues.

The market for some of our products is characterized by rapid change and technological improvements. Failure to respond in a timely and cost-effective way to these technological developments could result in serious harm to our business and operating results. We have derived, and we expect to continue to derive, a substantial portion of our revenues from the development and sale of products in the medical device industry. As a result, our success will depend, in part, on our ability to develop and market product offerings that respond in a timely manner to the technological advances of our competitors, evolving industry standards, and changing patient preferences. There is no assurance that we will keep up with technological improvements.

Our business could be adversely affected by reliance on sole suppliers.

Notwithstanding our current multiple supplier approach, certain essential product components may be supplied in the future by sole, or a limited group of, suppliers. Most of our products and components are purchased through purchase orders rather than through long-term supply agreements, and large volumes of inventory may not be maintained. There may be shortages and delays in obtaining certain product components. Disruption of the supply or inventory of components could result in a significant increase in the costs of these components or could result in an inability to meet the demand for our products. In addition, if a change in the manufacturer of a key component is required, qualification of a new supplier may result in delays and additional expenses in meeting customer demand for products. These factors could adversely affect our revenues and ability to retain our experienced sales force.

18

A third-party manufacturer’s inability to produce our goodsproducts’ components on time and to our specifications could result in lost revenue

revenue.

Third-party manufacturers assemble and manufacture to our specifications components of the NexWave and NeuroMove and some of our other products.products to our specifications. The inability of a manufacturer to ship orders of our products in a timely manner or to meet our quality standards could cause us to miss the delivery date requirements of our customerspatients for those items, which could result in cancellation of orders, refusal to accept deliveries, or a reduction in purchase prices, any of which could have a material adverse effect on our revenues. Because of the timing and seriousness of our business, and the medical device industry in particular, the dates on which customerspatients need and require shipments of products from us are critical. Further, because quality is a leading factor when customers,patients, doctors, health insurance providers, and distributors accept or reject goods, any decline in quality by our third-party manufacturers could be detrimental not only to a particular order, but also to our future relationship with that particular customer.patient.

We could experience cost increases or disruptions in supply of raw materials or other components used in our products.

Our third-party manufacturers that assemble and manufacture components for our products expect to incur significant costs related to procuring raw materials required to manufacture and assemble our product. The prices for these raw materials fluctuate depending on factors beyond our control, including market conditions and global demand for these materials and could adversely affect our business, prospects, financial condition, results of operations, and cash flows. Further, any delays or disruptions in our supply chain could harm our business. For example, COVID-19, including associated variants, could cause disruptions to and delays in our operations, including shortages and delays in the supply of certain parts, including semiconductors, materials and equipment necessary for the production of our products, and the internal designs and processes we or third-parties may adopt in an effort to remedy or mitigate impacts of such disruptions and delays could result in higher costs. In addition, our business also depends on the continued supply of battery cells for our products. We are exposed to multiple risks relating to availability and pricing of quality battery cells. These risks include:

14the inability or unwillingness of battery cell manufacturers to build or operate battery cell manufacturing plants to supply the numbers of battery cells (including the applicable chemistries) required to support the growth of the electric or plug-in hybrid vehicle industry as demand for such cells increases;
disruption in the supply of battery cells due to quality issues or recalls by the battery cell manufacturers; and
an increase in the cost or decrease in the available supply of raw materials used in battery cells, such as lithium, nickel, and cobalt.

Furthermore, currency fluctuations, tariffs, or shortages in petroleum and other economic or political conditions may result in significant increases in freight charges and raw material costs. Substantial increases in the prices for raw materials or components would increase our operating costs and could reduce our margins.

We depend upon third parties to manufacture and to supply key semiconductor chip components necessary for our products. We do not have long-term agreements with our semiconductor chip manufacturers and suppliers, and if these manufacturers or suppliers become unwilling or unable to provide an adequate supply of semiconductor chips, with respect to which there is a global shortage, we would not be able to find alternative sources in a timely manner and our business would be adversely impacted.

Semiconductor chips are a vital input component to the electrical architecture of our products, controlling wide aspects of the products’ operations. Many of the key semiconductor chips we use in our products come from limited or single sources of supply, and therefore a disruption with any one manufacturer or supplier in our supply chain would have an adverse effect on our ability to effectively manufacture and timely deliver our products. We do not have any long-term supply contracts with any suppliers and purchase chips on a purchase order basis. Due to our reliance on these semiconductor chips, we are subject to the risk of shortages and long lead times in their supply. We are in the process of identifying alternative manufacturers for semiconductor chips. We have in the past experienced, and may in the future experience, semiconductor chip shortages, and the availability and cost of these components would be difficult to predict. For example, our manufacturers may experience temporary or permanent disruptions in their manufacturing operations due to equipment breakdowns, labor strikes or shortages, natural disasters, component or material shortages, cost increases, acquisitions, insolvency, changes in legal or regulatory requirements, or other similar problems.

19

In particular, increased demand for semiconductor chips in 2020, due in part to the COVID-19 pandemic and increased demand for consumer electronics that use these chips, resulted in a severe global shortage of chips in 2021 and 2022. As a result, our ability to source semiconductor chips to be used in our products has been adversely affected. This shortage may result in increased chip delivery lead times, delays in the production of our products, and increased costs to source available semiconductor chips. To the extent this semiconductor chip shortage continues, and we are unable to mitigate the effects of this shortage, our ability to deliver sufficient quantities of our products to fulfill our preorders and to support our growth through sales to new customers would be adversely affected. In addition, we may be required to incur additional costs and expenses in managing ongoing chip shortages, including additional research and development expenses, engineering design, and development costs in the event that new suppliers must be onboarded on an expedited basis. Further, ongoing delays in production and shipment of products due to a continuing shortage of semiconductor chips may harm our reputation and discourage additional preorders and sales, and otherwise materially and adversely affect our business and operations.

If we need to replace manufacturers, our expenses and cost of goods could increase, resulting in smallerlow profit margins.

We compete with other companies for the production capacity of our manufacturers and import quota capacity. Some of these competitors have greater financial and other resources than we have and thus have an advantage in the competition for production and import quota capacity. If we experience a significant increase in demand, or if we need to replace an existing manufacturer, we may have to expand our third-party manufacturing capacity. We cannot assure that this additional capacity will be available when required on terms that are acceptable to us or similar to existing terms, which we have with our manufacturers, either from a production standpoint or a financial standpoint. We enter into a number of purchase order commitments specifying a time for delivery, method of payment, design and quality specifications, and other standard industry provisions, but we do not have long-term contracts with any manufacturer. None of the manufacturers we use produce our products exclusively. Should we be forced to replace one or more of our manufacturers, we may experience increased costs or an adverse operational impact due to delays in distribution and delivery of our products to our customers,patients, which could cause us to lose customerspatients or lose revenue because of late shipments.

Cyber-attacks and security vulnerabilities could lead to reduced revenue, increased costs, liability claims, or harm to our competitive position.

Increased sophistication and activitiesWe are a relatively small company with a limited number of perpetrators of cyber-attacks have resulted in an increase in information security risks in recent years. Hackers develop and deploy viruses, worms, and other malicious software programs that attack products and servicesstaff. Sales fluctuations and gain access to networks and data centers. If we were to experience difficulties maintaining existing systems or implementing new systems, we could incur significant losses due to disruptions in our operations. Additionally, these systems contain valuable proprietary and confidential information andemployee turnover may contain personal data of our customers. A security breach could result in disruptions of our internal systems and business applications, harm to our competitive position from the compromise of confidential business information, or subject us to liability under laws that protect personal data. As cyber threats continue to evolve, we may be required to expend additional resources to continue to enhance our information security measures and/or to investigate and remediate any information security vulnerabilities.  Any of these consequences would adversely affect our business.

We are a relatively small company. Consequently, compared to larger companies, sales fluctuations could have a greater impact on our revenue and margins.profitability on a quarter-to-quarter and year-to-year basis, and delays in patient orders could cause our operating results to vary significantly from quarter-to-quarter and year-to-year. In addition, as a small company we have limited staff and are heavily reliant on certain key personnel to operate our business. If a key employee were to leave the company, it could have a material impact on our business and results of operations, as we might not have sufficient depth in our staffing to fill the role that was previously being performed. A delay in filling the vacated position could put a strain on existing personnel, result in a failure to satisfy our contractual obligations, or to effectively implement our internal controls, which could materially harm our business.

If we are unable to retain the services of Mr. Sandgaard or if we are unable to successfully recruit qualified managerial and sales personnel, with experience in our business, we may not be able to continue our operations

Our success depends to a significant extent upon the continued service of Mr. Thomas Sandgaard, our Chief Executive Officer, and Founder, and beneficial owner of 53%approximately 50% of our outstanding stock.stock as of February 28, 2024. Loss of the services of Mr. Sandgaard could have a material adverse effect on our growth, revenues, and prospective business. There is currently no employment agreement with Mr. Sandgaard. We do not maintain key-man insurance on the life of Mr. Sandgaard. In addition, in order to successfully implement and manage our business plan, we will be dependent upon, among other things, successfully retaining and recruiting qualified managerial and sales personnel having experience in our business.personnel. Competition for qualified individuals is intense. Various factors, such as marketability of our products, our reputation, our liquidity, and sales commission structure can affect our ability to find, attract, or retain sales personnel. There can be no assurance that we will be able to find attract and retainattract qualified new employees and sales representatives and retain existing employees and sales representatives.

We need to maintain insurance coverage, which could become very expensive or have limited availability

availability.

Our marketing and salesales of medical device products and services createscreate an inherent risk of claims for product liability. As a result, we carry product liability insurance and will continue to maintain insurance in amounts we consider adequate to protect us from claims. We cannot, however, be assured that we have resources sufficient to satisfy liability claims in excess of policy limits if required to do so. Also, if we are subject to such liability claims, there is no assurance that our insurance provider will continue to insure us at current levels or that our insurance rates will not substantially rise in the future, resulting in increased costs to us or forcing us to either pay higher premiums or reduce our coverage amounts, which would result in increased liability to claims. In addition,

Although we do not manufacture the products we distribute, if one of the products distributed by us proves to be defective or is misused by a health care practitioner or patient, we may be subject to liability that could adversely affect our financial condition and results of operations.

Although we do not manufacture the products that we distribute, a defect in January 2017, wethe design or manufacture of a product distributed or serviced by us, or a failure of a product distributed by us to perform for the use specified, could have obtained directora material and officer insuranceadverse effect on our reputation in the industry and subject us to claims of liability for injuries and otherwise. Misuse of the product distributed by us by a practitioner or patient that covers currentresults in injury could similarly subject us to liability. Any substantial underinsured loss could have a material and prior periods.adverse effect on our business, financial condition, results of operations, and cash flows. Furthermore, any impairment of our reputation could have a material and adverse effect on our revenues and prospects for future business.

We depend upon obtaining regulatory approvalclearance of any new products and/or manufacturing operations we develop and maintain approvalsclearances of current products; failure to obtain or maintain such regulatory approvalsclearances could result in increased costs, lost revenue, penalties, and fines.

Before marketing anycertain new products, we will need to complete one or more clinical investigations of each product. There can be no assurance that the results of such clinical investigations will be favorable to us. We may not know the results of any study, favorable or unfavorable to us, until after the study has been completed. Such data must be submitted to the FDA as part of any regulatory filing seeking approvalclearance to market the product. Even if the results are favorable, the FDA may dispute the claims of safety, efficacy, or clinical utility and not allow the product to be marketed. The salesales price of the product may not be enough to recoup the amount of our investment in conducting the investigative studies, and we may expend significant funds on research and development on products that are rejected by the FDA. Some of our products are marketed based upon our interpretation of FDA regulation allowing for changes to an existing device. If our interpretations are incorrect, we could suffer consequences that could have a material adverse effect on our results of operations and cash flows and could result in fines and penalties. There can be no assurance that we will have the financial resources to complete development of any new products, or to complete the regulatory approvalclearance process, or to maintain regulatory compliance of existing products.

We may not be able to obtain clearance of a 510 (k)510(k) pre-market notification or grant of a de novo classification request or approval of a denovo or pre-market approval application with respect to any products on a timely basis, if at all.

If timely FDA clearance or approval of new products is not obtained, our business could be materially adversely affected. Clearance of a 510(k) pre-market notification or DeNovode novo application may also be required before marketing certain previously marketed products, which have been modified after they have been cleared. Should the FDA so require, the filing of a new 510(k) pre-market notification for the modification of the product may be required prior to marketing any modified devices.

device. To determine whether adequate compliance has been achieved, the FDA may inspect our facilities at any time. Such compliance can be difficult and costly to achieve and maintain. Our compliance status may change due to future changes in, or interpretations of, FDA regulations or other regulatory agencies. Such changes may result in the FDA withdrawing marketing clearance or requiring or requesting product recall. In addition, any changes or modifications to a device or its intended use may require us to reassess compliance with good manufacturing practices guidelines, potentially interrupting the marketing and sale of products. We may also fail to comply with complex FDA regulations due to their complexity or otherwise. Failure to comply with regulations could result in enforceable actions, including product seizures, product recalls, withdrawal of clearances or approvals, injunctions, and civil and criminal penalties, any of which could have a material adverse effect on our operating results and reputation.

Our products are subject to recall even after receiving FDA or foreign clearance or approval, which would harm our reputation and business.

We are subject to medical device reporting regulations that require us to report to the FDA or respective governmental authorities in other countries if our products cause or contribute to a death or serious injury or malfunction in a way that would be reasonably likely to cause or contribute to death or serious injury if the malfunction were to recur. The FDA and similar governmental authorities in other countries have the authority to require the recall of our products in the event of material deficiencies or defects in design or manufacturing. A government mandated or voluntary recall by us could occur as a result of component failures, manufacturing errors or design defects, including defects in labeling.

Any recall would divert managerial and financial resources and could harm our reputation with customers. We cannot assure you that we will not have product recalls in the future or that such recalls would not have a material adverse effect on our business. We have not undertaken any voluntary or mandatory recalls to date.

We continue to incur substantial expensesexpenses.

TheThis area of medical device research is subject to rapid and significant technological changes. Developments and advances in the medical industry by either competitors or other parties can affect our business in either a positive or negative manner. Developments and changes in technology that are favorable to us may significantly advance the potential of our research, while developments and advances in research methods outside of the methods we are using may severely hinder or completely halt completely our development.

We are a small company in terms of employees and technical and research resources and we have limited liquidity.resources. We expect to incur research and development, and sales and marketing, and general and administrative expenses. These amounts may increase, and recently have in connection with our efforts to expand our sales force, before any commensurate incremental revenue from these efforts may be obtained and may adversely affect our potential profits, and we may lack the liquidity to pay for such expenditures. These factors may also hinder our ability to meet changes in the medical industry as rapidly or effectively as competitors with more resources.

We may be unable to protect our trademarks, trade secrets and other intellectual property rights that are important to our business

We consider our trademarks, trade secrets and other intellectual property an integral component of our success. We rely on trademark law and trade secret protection and confidentiality agreements with employees, customers, partners and others to protect our intellectual property. Effective trademark and trade secret protection may not be available in every country in which our products are available. We currently own no patents. We cannot be certain that we have taken adequate steps to protect our intellectual property, especially in countries where the laws may not protect our rights as fully as in the United States. In addition, if our third-party confidentiality agreements are breached there may not be an adequate remedy available to us. If our trade secrets become publicly known, we may lose competitive advantages.

Substantial costs could be incurred defending against claims of infringement

intellectual property infringement.

Other companies, including competitors, may obtain patents or other proprietary intellectual property rights that would limit, interfere with, or otherwise circumscribe Zynex’sour ability to make, use, or sell products. Should there be a successful claim of infringement against us, and if we could not license the alleged infringed technology at a reasonable cost, our business and operating results could be adversely affected. There has been substantial litigation regarding patent and other intellectual property rights in the medical device industry. The validity and breadth of claims covered in medical technology patents involve complex legal and factual questions for which important legal principles remain unresolved. Any litigation claims against us, independent of their validity, may result in substantial costs and the diversion of resources with no assurance of success. Intellectual property claims could cause us to:

Ceasecease selling, incorporating, or using products that incorporate the challenged intellectual property:property;
Obtainobtain a license from the holder of the infringed intellectual property right, which may not be available on reasonable terms, if at all; and
Re-design Zynex’sre-design our products excluding the infringed intellectual property, which may not be possible.

We have not undertaken any voluntary or involuntary recalls to date.

Our principal executive officer owns a controlling interest in our voting stock and investors will not have any voice in our management

Our President, Chief Executive Officer, and Chairman, , Thomas Sandgaard, beneficially owns approximately 53% of our outstanding common stock as of February 22, 2018. As a result, Mr. Sandgaard has the ability to control substantially all day to day operations of our company and all matters submitted to our stockholders for approval, including:

Election of our board of directors;
Removal of any of our directors;
Amendment of our certificate of incorporation or bylaws;
Approval of significant corporate transactions, such as a sale, merger or liquidation of our Company; and
Adoption of measures that could delay or prevent a change in control or impede a merger, takeover or other business combination involving us.

We are a relatively small company with a limited number of products and staff. Sales fluctuations and employee turnover may adversely affect our business

We are a relatively small company. Consequently, compared to larger companies, sales fluctuations could have a greater impact on our revenue and profitability on a quarter-to-quarter and year-to-year basis and delays in patient orders could cause our operating results to vary significantly from quarter to quarter and year-to-year. In addition, as a small company we have limited staff and are heavily reliant on certain key personnel to operate our business. If a key employee were to leave the company it could have a material impact on our business and results of operations as we might not have sufficient depth in our staffing to fill the role that was previously being performed. A delay in filling the vacated position could put a strain on existing personnel or result in a failure to satisfy our contractual obligations or to effectively implement our internal controls, and materially harm our business.

We’ve had material weaknesses in our internal controls over financial reporting in previous periods

We believe we have remediated prior material weaknesses but as a small company with limited resources, it is possible we identify material weaknesses in the future. If we do not remediate any such weaknesses in the future, in addition to any impact on our stock price, it could also impact our ability to raise capital and could affect adversely our reputation, which collaterally could affect our ability to retain sales personnel and business relationships with insurance companies paying for our products and vendors.

We may fail to protect the privacy, integrity and security of customer information

information.

We possess and process sensitive customer information and Protected Health Information protected by the Health Insurance Portability and Affordability Act (“HIPAA”). While we have taken reasonable and appropriate steps to protect that information, if our security procedures and controls were compromised, it could harm our business, reputation, results of operations, and financial condition and may increase the costs we incur to protect against such information security breaches, such as increased investment in technology, the costs of compliance with health carehealthcare privacy and consumer protection laws. A compromise of our privacy or security procedures could also subject us to liability under certain health carehealthcare privacy laws applicable to us.

Other federal and state laws restrict the use and protect the privacy and security of personally identifiable information are, in many cases, are not preempted by HIPAA and may be subject to varying interpretations by the courts and government agencies. These varying interpretations can create complex compliance issues for us and our partners and potentially expose us to additional expense, adverse publicity and liability, any of which could adversely affect our business. There is ongoing concern from privacy advocates, regulators and others regarding data privacy and security issues, and the number of jurisdictions with data privacy and security laws has been increasing. Also, there are ongoing public policy discussions regarding whether the standards for de-identification, anonymization or pseudonymization of health information are sufficient, and the risk of re-identification sufficiently small, to adequately protect patient privacy. We expect that there will continue to be new proposed and amended laws, regulations and industry standards concerning privacy, data protection and information security in the United States, such as the California Consumer Privacy Act (“CCPA”), as amended by the California Privacy Rights Act (“CPRA”), which amendments went into effect on January 1, 2023, The CCPA creates specific obligations with respect to processing and storing personal information, and the CPRA amendments created a new state agency that is vested with authority to implement and enforce the CCPA. Additionally, a similar law went into effect in Virginia on January 1, 2023, and further US-state comprehensive privacy laws are set to go into effect throughout 2023, including laws in Colorado, Connecticut, and Utah. These laws are substantially similar in scope and contain many of the same requirements and exceptions as the CCPA, including a general exemption for clinical trial data and limited obligations for entities regulated by HIPAA. However, we cannot yet determine the full impact these laws or other such future laws, regulations and standards may have on our current or future business. Any of these laws may broaden their scope in the future, and similar laws have been proposed on both a federal level and in more than half of the states in the U.S. A number of other states have proposed new privacy laws, some of which are similar to the above discussed recently passed laws. Such proposed legislation, if enacted, may add additional complexity, variation in requirements, restrictions and potential legal risk, require additional investment of resources in compliance programs, impact strategies and the availability of previously useful data and could result in increased compliance costs and/or changes in business practices and policies. The existence of comprehensive privacy laws in different states in the country would make our compliance obligations more complex and costly and may increase the likelihood that we may be subject to enforcement actions or otherwise incur liability for noncompliance.

Cyber-attacks and security vulnerabilities could lead to reduced revenue, increased costs, liability claims, or harm to our competitive position.

Increased sophistication and activities of perpetrators of cyber-attacks have resulted in an increase in information security risks in recent years. Hackers develop and deploy viruses, worms, and other malicious software programs that attack products and services and gain access to networks and data centers. In addition to extracting sensitive information, such attacks could include the deployment of harmful malware, ransomware, denial-of-service attacks, social engineering and other means to affect service reliability and threaten the confidentiality, integrity and availability of information. The prevalent use of mobile devices also increases the risk of data security incidents. If we experience difficulties maintaining existing systems or implementing new systems, we could incur significant losses due to disruptions in our operations. Additionally, these systems contain valuable proprietary and confidential information and may contain personal data of our customers. While we believe we have taken reasonable steps to protect such data, techniques used to gain unauthorized access to data and systems, disable or degrade service, or sabotage systems, are constantly evolving, and we may be unable to anticipate such techniques or implement adequate preventative measures to avoid unauthorized access or other adverse impacts to such data or our systems. In addition, some of our third-party service providers and partners also collect and/or store our sensitive information and our customers’ data on our behalf, and these service providers and partners are subject to similar threats of cyber-attacks and other malicious internet-based activities, which could also expose us to risk of loss, litigation, and potential liability. A security breach could result in disruptions of our internal systems and business applications, harm

23

to our competitive position from the compromise of confidential business information, or subject us to liability under laws that protect personal data. Additionally, actual, potential or anticipated attacks may cause us to incur increasing costs, including costs to deploy additional personnel and protection technologies, train employees, and engage third-party experts and consultants. Specifically, as cyber threats continue to evolve, we may be required to expend additional resources to continue to enhance our information security measures and/or to investigate and remediate any information security vulnerabilities. Any of these consequences would adversely affect our revenue and margins. Additionally, although we maintain cybersecurity insurance coverage, we cannot be certain that such coverage will be adequate for data security liabilities actually incurred, will cover any indemnification claims against us relating to any incident, will continue to be available to us on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on our reputation, business, prospects, results of operations and financial condition.

We have identified material weaknesses in our internal controls over financial reporting and may identify additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls, which may result in material misstatements of our consolidated financial statements or cause us to fail to meet our periodic reporting obligations.

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 a company’s annual or interim financial statements will not be prevented or detected on a timely basis. We identified a material weakness in our internal controls over financial reporting as of December 31, 2023 and 2022, related to information technology general controls (“ITGCs”) that were not designed and operating effectively to ensure (i) appropriate segregation of duties was in place to perform program changes and (ii) the activities of individuals with access to modify data and make program changes were appropriately monitored. Business process controls (automated and manual) that are dependent on the affected ITGCs were also deemed ineffective because they could have been adversely impacted. Also as of December 31, 2023, we identified a material weakness in our communications with our independent auditors as it relates to open or pending financial statement adjustments and the timing of decisions to take write-offs. Although the material weaknesses identified above did not result in any material misstatements in our consolidated financial statements for the periods presented and there were no changes to previously released financial results, our management concluded that these control weaknesses constitute a material weakness and that our internal control was not effective as of December 31, 2023.

Our management is committed to take comprehensive actions to remediate the material weakness in internal control over financial reporting. We are in the process of developing and implementing remediation plans to address the material weakness described above.

While we are committed to designing and implementing new controls and measures to remediate these material weaknesses, we cannot assure you that the measures will be sufficient to remediate the material weaknesses or avoid the identification of additional material weaknesses in the future. Our failure to implement and maintain effective internal control over financial reporting could result in errors in our consolidated financial statements that could result in a restatement of our financial statements and could cause us to fail to meet our periodic reporting obligations, any of which could diminish investor confidence in us and cause a decline in the price of our common stock.

Expansion of our operations and sales internationally may subject us to additional risks, including risks associated with unexpected events

events.

A component of our growth strategy is to expand our operations and sales internationally. There can be no assurance that we will be able to successfully market, sell, and deliver our products in foreign markets, or that we will be able to successfully expand our international operations. Global operations could cause us to be subject to unexpected, uncontrollable and rapidly changing risks, events, and circumstances.

17

The following factors, among others, could adversely affect our business, financial condition and results of operations:

difficulties in managing foreign operations and attracting and retaining appropriate levels of senior management and staffing;
longer cash collection cycles;
proper compliance with local tax laws which can be complex and may result in unintended adverse tax consequences;

24

difficulties in enforcing agreements through foreign legal systems;
failure to properly comply with U.S. and foreign laws and regulations applicable to our foreign activities including, without limitation, product approval, healthcare and employment law requirements and the Foreign Corrupt Practices Act;

difficulties in managing foreign operations and attracting and retaining appropriate levels of senior management and staffing;
longer cash collection cycles;
proper compliance with local tax laws which can be complex and may result in unintended adverse tax consequences;
difficulties in enforcing agreements through foreign legal systems;
fluctuations in exchange rates that may affect product demand and may adversely affect the profitability in U.S. dollars of the products we provide in foreign markets;
the ability to efficiently repatriate cash to the United States and transfer cash between foreign jurisdictions; and
changes in general economic conditions or political circumstances in countries where we operate.

Our acquisition of other companies could require significant management attention, disrupt our business, dilute stockholder value and adversely affect our operating results.

As part of our business strategy, we have made and may in the future acquire or make investments in other companies, solutions or technologies to, among other reasons, expand or enhance our product offerings. In the future, any significant acquisition would require the consent of our lenders. Any failure to receive such consent could delay or prohibit us from acquiring companies that we believe could enhance our business.

We may not ultimately strengthen our competitive position or achieve our goals from our recent or any future acquisition, and any acquisitions we complete could be viewed negatively by users, customers, partners or investors. In addition, if we fail to successfully integrate such acquisitions, or the technologies associated with such acquisitions, into our company, the revenues and operating results of the combined company could be adversely affected. For example, in December 2021 we acquired Kestrel Labs, Inc. and we must effectively integrate the personnel, products, technologies and customers and develop and motivate new employees. In addition, we may not be able to successfully retain the customers and key personnel of such acquisitions over the longer term, which could also adversely affect our business. The integration of our recently acquired business or future-acquired business will require significant time and resources, and we may not be able to manage the process successfully. We may not successfully evaluate or utilize the acquired business and accurately forecast the financial impact of the acquisition, including accounting charges.

We may have to pay cash, incur debt or issue equity securities to pay for any acquisition, each of which could affect our financial condition or the value of our capital stock. For example, in connection with our acquisition of Kestrel Labs, Inc., we paid an approximate value of $30.5 million, consisting of $16.1 million in cash which was financed through Bank of America N.A. and approximately $14.4 million in shares of our common stock, a portion of which was to be held in escrow. To fund any future acquisition, we may issue equity, which would result in dilution to our stockholders, or incur more debt, which would result in increased fixed obligations and could subject us to additional covenants or other restrictions that would impede our ability to manage our operations.

If we are not able to integrate acquired businesses successfully, our business could be harmed.

Our inability to successfully integrate our recent and future acquisitions could impede us from realizing all of the benefits of those acquisitions and could severely weaken our business operations. The integration process may disrupt our business and, if implemented ineffectively, may preclude realization of the full benefits expected by us and could harm our results of operations. In addition, the overall integration of the combining companies may result in unanticipated problems, expenses, liabilities, and competitive responses, and may cause our stock price to decline. The difficulties of integrating an acquisition include, among others:

unanticipated issues in integration of information, communications, and other systems;
unanticipated incompatibility of logistics, marketing, and administration methods;
maintaining employee morale and retaining key employees;
integrating the business cultures of both companies;

25

preserving important strategic client relationships;
consolidating corporate and administrative infrastructures and eliminating duplicative operations; and
coordinating geographically separate organizations.

In addition, even if the operations of an acquisition are integrated successfully, we may not realize the full benefits of the acquisition, including the synergies, cost savings, or growth opportunities that we expect. These benefits may not be achieved within the anticipated time frame, or at all. For example, the failure to get regulatory approval to sell certain products of an acquired business may significantly reduce the anticipated benefits of the acquisition and could harm our results of operations, even if we have put in place contingencies for the delivery of closing consideration, such as the escrowed shares initially held back in our acquisition of Kestrel Labs, Inc. Further, acquisitions may also cause us to:

issue securities that would dilute our current stockholders’ ownership percentage;
use a substantial portion of our cash resources;
increase our interest expense, leverage, and debt service requirements if we incur additional debt to pay for an acquisition;
assume liabilities, including environmental liabilities, for which we do not have indemnification from the former owners or have indemnification that may be subject to dispute or concerns regarding the creditworthiness of the former owners;
record goodwill and non-amortizable intangible assets that are subject to impairment testing on a regular basis and potential impairment charges;
experience volatility in earnings due to changes in contingent consideration related to acquisition liability estimates;
incur amortization expenses related to certain intangible assets;
lose existing or potential contracts as a result of conflict of interest issues;
incur large and immediate write-offs; or
become subject to litigation.

Changes in financial accounting standards or practices may cause adverse, unexpected financial reporting fluctuations and affect our reported results of operations.

We are required to prepare our financial statements in accordance with generally accepted accounting principles in the United States of America (“GAAP”), which is periodically revised and/or expanded. From time to time, we are required to adopt new or revised accounting standards issued by recognized authoritative bodies, including the FASBFinancial Accounting Standards Board (“FASB”) and the SEC. It is possible that future accounting standards we are required to adopt may require additional changes to the current accounting treatment that we apply to our financial statements and may require us to make significant changes to our reporting systems. Such changes could result in a material adverse impact on our business, results of operations and financial condition. For example, effective January 1, 2018, we were required

The conversion feature of our convertible senior notes, if triggered, may adversely affect our financial condition and operating results.

We have outstanding a total of $60 million of convertible senior notes. See Note 8: Convertible Senior Notes to adopt ASC 606.

RISKS RELATINGRELATED TO OUR COMMON STOCK

Our common stock may be subject to the “penny stock” rules of the SEC and the trading market in our securities is limited, which makes transactions in our stock cumbersome and may reduce the value of an investment in our stock

Since our common stock is not listed or quoted on any stock exchange and no other exemptions may apply, trading in our common stock on the OTC Markets may be subject to the “penny stock” rules of the SEC. These rules require, among other things, that any broker engaging in a transaction in our securities provide its customers with a risk disclosure document, disclosure of market quotations, if any, disclosure of the compensation of the broker and its salespersons in the transaction, and monthly account statements showing the market values of our securities held in the customer’s accounts. The brokers must provide bid and offer quotations and compensation information before making any purchase or sale of a penny stock and also provide this information in the customer’s confirmation. Generally, brokers may be less willing to execute transactions in securities subject to the “penny stock” rules. This may make it more difficult for investors to dispose of our common stock and cause a decline in the market value of our stock.

Sales of significant amounts of shares held by Mr. Sandgaard, or the prospect of these sales, could adversely affect the market price of our common stock

Sales of significant amounts of shares held by Mr. Sandgaard, or the prospect of these sales, could adversely affect the market price of our common stock. As a resolution in certain issues in his divorce, in December 2015 Mr. Sandgaard transferred 250,000 shares of common stock he owned to the former Mrs. Sandgaard, which shares will become tradeable by Ms. Sandgaard after complying with the legal requirements under Rule 144 and other guidance. Mr. Sandgaard’s stock ownership may discourage a potential acquirer from making a tender offer or otherwise attempting to obtain control of us,the Company, which in turn could reduce our stock price or prevent our stockholders from realizing a premium over our stock price. Mr. Sandgaard has no control whether or when Ms. Sandgaard may choose to sell those shares or other shares of the Company’s common stock she may own.

Because we have no plans to pay dividends on our common stock, investors must look solely to stock appreciation for a return on their investment in us

We do not anticipate paying any cash dividends on our common stock in the foreseeable future.  We currently intend to retain all future earnings to fund the development and growth of our business.  Any payment of future dividends will be at the discretion of our board of directors and will depend on, among other things, our earnings, financial condition, capital requirements, level of indebtedness, statutory and contractual restrictions applying to the payment of dividends and other considerations that the board of directors deems relevant.  

 Investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize a return on their current investment.  Investors seeking cash dividends should not purchase our common stock. Given the extremely small trading volume, it is unlikely that any shareholder will be able to achieve a significant profit even if the stock price rises (of which there can be no assurance).

18

Our statues as a ‘controlled company’ could make our class A common stock less attractive to some investors or otherwise harm our stock price.

Although our common stock is currently quoted on the OTCQB, because we qualify as a "controlled company" under the corporate governance rules for listed companies, we would not be required to have a majority of our board of directors be independent if we were a listed company, nor would we be required to have a compensation committee or an independent nominating function. Accordingly, should the interests of our controlling stockholder differ from those of other stockholders, the otherexisting stockholders may not have the same protections afforded to stockholders of companies that are subject to all corporate governance rules. Our status as a controlled company could make our common stock less attractive to some investors or otherwise harm our stock price.

Our existing shareholders have experienced dilution as a result of shares issued to the broker-dealer involved in our recent placement of debt and will experience further dilution if we elect to raise equity capital to meet our liquidity needs

Due to our past liquidity issues, we have had to raisePreviously, we’ve raised capital in the form of debt and/or equity to meet our working capital needs. We may also be requiredchoose to issue equity (or debt)or debt securities in the future to meet our liquidity or other needs which would result in additional dilution to our existing stockholders. Although we will attempt to minimize the dilutive impact of any future capital-raising activities, we cannot offer any assurance that we will be able to do so. If we raise additional working capital, weWe may have to issue additional shares of our common stock at prices at a discount from the then-current market price of our common stock. If we raise additional working capital, existing stockholders may experience dilution.

We paid a dividend on our common stock, and cash used to pay dividends will not be available for other corporate purposes

In 2018, our Board of Directors declared a dividend of $0.07 per share, which was paid in January 2019. In 2021, our Board of Directors declared a dividend of $0.10 per share, which was paid in January 2022. The decision to pay dividends in the future will depend on general business conditions, the impact of such payment on our financial condition, and other factors our Board of Directors may consider. If we elect to pay future dividends, this could reduce our cash reserves to levels that may be inadequate to fund expansions to our business plan or unanticipated contingent liabilities.

Our stock price could become more volatile and your investment could lose value.

All of the factors discussed in this section could affect our stock price. A significant drop in our stock price could also expose us to the risk of securities class actions lawsuits, which could result in substantial costs and divert management’s attention and resources, which could adversely affect our business.

Conversion of our convertible senior notes into common stock may dilute the ownership interests of existing stockholders or may otherwise depress the price of our common stock.

If it were to occur, the conversion of convertible senior notes would dilute the ownership interests of existing stockholders to the extent we deliver shares of common stock upon conversion. Any sales in the public market of such shares could adversely affect prevailing market prices of our common stock. In addition, the existence of the convertible senior notes and the anticipated conversion of the notes into shares of our common stock could depress the price of our common stock.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

We recognize the critical importance of developing, implementing, and maintaining robust cybersecurity measures to safeguard our information systems and protect the confidentiality, integrity, and availability of our data.

Managing Material Risks & Integrated Overall Risk Management

We have strategically integrated cybersecurity risk management into our broader risk management framework to promote a company-wide culture of cybersecurity risk management. This integration ensures that cybersecurity considerations are an integral part of our decision-making processes at every level. Our management team works closely with our IT department to continuously evaluate and address cybersecurity risks in alignment with our business objectives and operational needs.

Oversee Third-party Risk

Because we are aware of the risks associated with third-party service providers, we have implemented stringent processes to oversee and manage these risks. We conduct thorough security assessments of all third-party providers before engagement and maintain ongoing monitoring to ensure compliance with our cybersecurity standards. The monitoring includes annual assessments of the SOC reports of our providers and implementing complementary controls. This approach is designed to mitigate risks related to data breaches or other security incidents originating from third-parties.

Risks from Cybersecurity Threats

We have not encountered cybersecurity challenges that have materially impaired our operations or financial standing.

Inflation Reduction Act

LIQUIDITY

During 2013-2015,On August 16, 2022, President Biden signed the Company suffered operating lossesInflation Reduction Act of 2022, or IRA, into law, which caused a lackamong other things, (i) directs the U.S. Department of liquidityHealth and Human Services, or HHS, to negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare, and subjects drug manufacturers to civil monetary penalties and a substantial working capital deficit. This raised substantial doubt about the Company’s ability to continue aspotential excise tax for offering a going concern.

During 2016, the Company generated net income during Q3 and Q4 and combined with the profitability in 2017, the Company has recorded six consecutive profitable quarters, paid off its line of credit with Triumph Healthcare Finance, a division of TBK Bank, SSB, formerly known as Triumph Community Bank, (“Triumph”) (Note 9) and generated cash reserves and positive working capital.

As a result, in accordance with Accounting Standards Codification (“ASC”) 205-40, Presentation of Financial Statements – Going Concern, as of December 31, 2017, management evaluated whether there are conditions and eventsprice that raise doubt about the entity’s ability to continue as a going concern and concluded there is not equal to or less than the negotiated “maximum fair price” under the law; (ii) imposes rebates under Medicare Part B and Medicare Part D to penalize drug price increases that outpace inflation; and (iii) redesigns the Medicare Part D program, increasing manufacturer rebates within the catastrophic coverage phase. The IRA permits HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. These provisions began to take effect progressively beginning in fiscal year 2023, although they have been subject to legal challenges. It is currently unclear how the IRA will be effectuated but is likely to have a significant doubt.impact on the pharmaceutical industry.

The IRA also includes various tax provisions, including an excise tax on stock repurchases, expanded tax credits for clean energy incentives, and a corporate alternative minimum tax that generally applies to U.S. corporations with average adjusted financial statement income over a three-year period in excess of $1 billion. The Company is currently abledoes not expect these tax provisions to meetmaterially impact its obligations as they become due within one year. Management’s evaluation is based only on relevant conditions and events that are known and reasonably knowable as of the date of these financial statements.

Net Revenue

Net revenues are comprised of product device and product supply sales, reducedconstrained by estimated Third-party Payorsthird-party payer reimbursement deductions and an allowance for uncollectible amounts, if needed.deductions. The reserve for billing allowance adjustments and allowance for uncollectible accounts are adjusted on an ongoing basis in conjunction with the processing of Third-party Payorthird-party payer insurance claims and other customer collection history. Inherent in these estimates is the risk that they will have to be revised as additional information becomes available and constraints are released. If initial estimates are updated these changes are accounted for as increases or decreases in the transaction price. Assuming the underlying performance obligation to which the change in price relates has already been satisfied, those changes in transaction price are immediately recognized as increases or decreases in revenue (not credit losses (bad debt expense)) in the period in which the estimate changes.

Product device revenue is primarily comprised of sales and rentals of our transcutaneous electrical nerve stimulation (“TENS”)electrotherapy products and also includes complementary rehabilitation products such as our cervical traction, lumbar support, bracing, and hot/cold therapy products. Supply

Supplies revenue includesis primarily comprised of sales of our consumable supplies related primarily to our TENS products.

We also sell consumable supplies for all patients using our electrotherapy products, consisting primarily of surface electrodes and batteries. Revenue for the electrotherapy productsrelated to both devices and supplies is reported net, after adjustments for estimated insurance companythird-party payer reimbursement deductions and estimated allowance for uncollectible accounts. The deductions are known throughout the health carehealthcare industry as “billing adjustments”billing adjustments whereby the healthcare insurers unilaterally reduce the amount they reimburse for our products as compared to the sales prices charged by us. The deductions from gross revenue also take into account the estimated denials, net of resubmitted billings of claims for products placed with patients which may affect collectability. See our

34

Significant Accounting Policies in Note 2 to the Consolidated Financial Statements for a more complete explanation of our revenue recognition policies.

We continually pursue improvements to our processes of billing insurance providers. We review all claims which are initially denied or not received. As these situations are identified and resolved, the appropriate party is appropriately rebilled (resubmitted) or, for those claims not previously billed, billed.

26

We frequentlyoccasionally receive, and expect to continue to receive, refund requests from insurance providers relating to specific patients and dates of service. Billing and reimbursement disputes are very common in our industry. These requests are sometimes related to a few patients and other times include a significant number of refund claims in a single request. We review and evaluate these requests and determine if any refund is appropriate. We also review claims that have been resubmitted or where we are rebilling or pursuing additional reimbursement from that insurance provider. We frequently have significant offsets against such refund requests which may result in amounts that are due to us in excess of the amounts of refunds requested by the insurance providers. Therefore, at the time of receipt of such refund requests we are generally unable to determine if a refund request is valid.

As of December 31, 2017, we believe we have an adequate allowance for billing adjustments relating to known insurance disputes and refund requests. However, no assurances can be given with respect to such estimates of reimbursements and offsets or the ultimate outcome of any refund requests.

Net revenue increased $10.1$26.2 million or 76%17% to $23.4$184.3 million for the year ended December 31, 2017,2023, from $13.3$158.2 million for the year ended December 31, 2016.2022. The growth in net revenue is primarily related to the 43% growth in device orders which led to an increased customer base whichand drove higher sales of consumable supplies and improvements in our billing and collection procedures.supplies. During the fourth quarter of 2023, the Company placed an allowance of $6.2 million on receivables which were determined to be uncollectible. The allowance was recorded to net revenue during the period.

Product Device Revenue

Product deviceDevice revenue is related to the purchase or lease of our electrotherapy products as well as complementary products including cervical traction, lumbar support, knee braces and hot/cold therapy products. Product deviceDevice revenue decreased $0.2increased $15.3 million or 3%35% to $8.8$58.8 million for the year ended December 31, 2017,2023, from $9.0$43.5 million for the year ended December 31, 2016.2022. The decreaseincrease in product device revenue is primarily related to fewer orders in 2017, partially offset by improvementsthe growth in our billingdevice and collection procedures.complementary product orders of 43% from 2022 to 2023 as a result of increased sales representative productivity.

Product Supplies Revenue

As a percentage of revenue, cost of revenue –product– devices and supply decreased tosupplies remained flat at 21% for the years ended December 31, 2023 and 2022, respectively.

Sales and Marketing Expense

The decreaseincrease in sales and marketing expense is primarily due to an increased head count in our direct sales force and sales operations group, which includes our patient experience team, as well as increased compensation related to higher-than-normal inflation in the U.S. Increased orders also resulted in higher sales commissions as well as travel expenses. As a percentage of revenue, sales and marketing expense increased to 47% from 42% during the year ended December 31, 2023 compared the same period in 2022. The increase as a percentage of revenue is primarily due to the aforementioned increase in expenses, partially offset by increased revenue during the period.year ended December 31, 2023.

The increase in selling, general and administrative expense is primarily due to incentive compensation and stock compensation expense related to warrants issued. the following:

an increase of $5.7 million in compensation and benefits expense driven by headcount growth in our ZMI reimbursement team, which is directly related to our 43% order growth during the period;
an increase of $1.5 million in compensation and benefits expense driven by headcount growth and inflationary salary increases for ZMS; and

Other Income (Expense)

Other income was $1.8 million for the year ended December 31, 2023, of which $2.9 million related to a gain on the change in fair value of contingent consideration.

As of December 31, 2017,2023, we had working capital of $4.4$69.3 million, compared to a deficit$48.5 million as of December 31, 20162022. The principal source of $4.3 million.working capital was $44.6 million in cash and cash equivalents and $26.8 million in accounts receivable. The increase in working capital is primarily due todriven from the offering of Convertible Senior Notes and the profitability during 2017.the year ended December 31, 2023. This increase was offset by the purchase of $37.9 million in treasury stock in 2023. We generated $8.3$17.8 million and $13.7 million in positive operating cash flows during 2017the years ended December 31, 2023 and expect to generate positive cash flows from operations going forward.

CRITICAL ACCOUNTING ESTIMATES

In preparing our consolidated financial statements in accordance with GAAP, we are required to make estimates and assumptions that affect the amounts of assets, liabilities, revenue, costs and expenses, and disclosure of contingent liabilities that are reported in the consolidated financial statements and accompanying disclosures. We believe that the estimates, assumptions and judgments involved in the accounting policies described below have the greatest potential impact on our financial statements because they involve the most difficult, subjective or complex judgments about the effect of matters that are inherently uncertain. Therefore, we consider these to be our critical accounting estimates. Accordingly, we evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates and assumptions. See Note 2 to the Consolidated Financial Statements of this Annual Report on Form 10-K for information about these critical accounting policies, as well as a description our other accounting policies.

Revenue Recognition and Accounts Receivable

In the fourth quarterhealthcare industry there is often a third party involved that will pay on the patients’ behalf for purchased or leased devices and supplies. The terms of 2012, ZEU entered into an annual rental agreementthe separate arrangement impact certain aspects of the contract with patients covered by third party payers, such as contract type, performance obligations and transaction price, but for a small office/warehouse space (approximately 250 square feet)purposes of revenue recognition the contract with the customer refers to the arrangement between the Company and the patient.

The Company does not have any material deferred revenue in Denmark, whichthe normal course of business as each performance obligation is met upon delivery of goods to the patient.

Device Sales

Device sales can be terminated within 120 days’ notice. Annual rent totals 45,000 Danish kroner (approximately $7,500 USD using 2017 year-end exchange rates).in the form of a purchase or a lease.

Off – Balance Sheet Arrangements

As of December 31, 2017 and 2016, we had no off-balance sheet arrangements or obligations.

CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of our financial condition and results of operations are based upon our financial statements, which have been preparedRevenue for purchased devices is recognized in accordance with accounting principles generally acceptedAccounting Standards Codification (“ASC”) 606 – “Revenue from Contracts with Customers” (ASC 606) when the device is delivered to the patient and all performance obligations are fulfilled.

Revenue related to devices out on lease is recognized in accordance with ASC 842, Leases. Using the United States of America.

We have identifiedguidance in ASC 842, we concluded our transactions should be accounted for as operating leases based on the policies below as critical to our business operations and the understanding of our results of operations.following criteria below:

29The lease does not transfer ownership of the underlying asset to the lessee by the end of the lease term.
The lease does not grant the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise.
The lease term is month to month, which does not meet the major part of the remaining economic life of the underlying asset. However, if the commencement date falls at or near the end of the economic life of the underlying asset, this criterion shall not be used for purposes of classifying the lease.
There is no residual value guaranteed and the present value of the sum of the lease payments does not equal or exceed substantially all of the fair value of the underlying asset.
The underlying asset is expected to have alternative uses to the lessor at the end of the lease term.

Revenue Recognition, Allowance forBilling Adjustments and Collectability

The Company recognizes revenue when eachLease commencement occurs upon delivery of the following four conditions are met: 1) a contract or sales arrangement exists, 2) products have been delivered and title has transferred 3) the price of the products or services is fixed or determinable, and 4) collectability is reasonably assured. The Company recognizes revenue for medical units and supplies when we receive notice that the product has been prescribed and delivereddevice to the patient. The Company priorretains title to recognizingthe leased device and those devices are classified as property and equipment on the balance sheet. Since our leases are month-to-month and can be returned by the patient at any time, revenue verifies the patient’s insurance coverage or obtains the insurance company preauthorization, when required. Revenue from supplies is recognized upon delivery. Revenue from sales to distributorsmonthly for the duration of the period in which the patient retains the device.

38

Supplies

Supplies revenue is recognized whenonce supplies are delivered to the Company receives notice of receipt by the distributor. Revenue is reported net, after adjustments for estimated insurance company or governmental agency (collectively “Third-party Payors”) reimbursement deductions and, for wholesale customers and patient billings, an allowance for uncollectible accounts. The Third-party Payor reimbursement deductions are known throughout the health care industry as “billing adjustments” whereby the Third-party Payors unilaterally reduce the amount they reimbursepatient. Supplies needed for the Company’s products.device can be set up as a recurring shipment or ordered through the customer support team or online store as needed.

Variable Consideration

A significant portion of the Company’s revenues are derived, and the related receivables are due, from Third-party Payors. The nature of these receivables withinpatients with commercial or government health insurance plans. Revenues are estimated using the medical industry has typically resulted in long collection cycles. The process of determining what products will be reimbursedportfolio approach by Third-party Payors and the amounts that they will reimburse is complex and depends on conditions and procedures that vary among providers and may change from time to time. The Company maintains an allowance for billing adjustments and if necessary, an allowance for doubtful accounts. Billing adjustments result from reimbursements from Third-party Payors that are less than amounts claimed and from where the amount claimed by the Company exceeds the Third-party Payors usual, customary and reasonable reimbursement rate. The Company determines the amount of the allowance and adjusts it at the end of each reporting period,third party payer type based on a number of factors, includingupon historical rates of collection, the aging of the receivables, trends in the historical reimbursement rates of collectionby third-party payer types and current relationships and experience with the Third-party Payors. If the rates of collection of past-due receivables recordedthird-party payers, which includes estimated constraints for previous fiscal periods changes, or if there is a trend in the rates of collection on those receivables, the Company may be required to change the rate at which it provides for additions to the allowance. A change in the rates of the Company’s collections can result from a number of factors, including experience and training of billing personnel, changes in the reimbursement policies or practices of Third-party Payors, or changes in industry rates of reimbursement. We believe we have a sufficient history of collection experience to estimate the net collectible amounts by payor. However, changes to thethird-party payer refund requests, deductions, allowance for billing adjustments and uncollectible accounts, which are recorded as a reduction of revenue, have historically fluctuated and may continue to fluctuate significantly from quarter to quarter and year to year.

Due to the nature of the medical industry and the reimbursement environment in which the Company operates, estimates are required to record net revenues and accounts receivable at their net realizable values (also known as net collectible value).billing allowance adjustments. Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically,available and constraints are released. If initial estimates are updated these changes are accounted for as increases or decreases in the transaction price. Assuming the underlying performance obligation to which the change in price relates has already been satisfied, those changes in transaction price are immediately recognized as increases or decreases in revenue (not credit losses (bad debt expense)) in the period in which the estimate changes. Additionally, the complexity of third-party billing arrangements and the uncertainty of reimbursement amounts for certain products or services from payorsthird-party payers or unanticipated requirements to refund payments previously received may result in adjustments to amounts originally recorded. Due to continuing changes in the health carehealthcare industry and third-party payer reimbursement, as well as changes in our billing practices to increase cash collections, it is possible that management’s estimatesour forecasting model to estimate collections could change, in the near term, which could have an impact on our results of operations and cash flows. Any differences between estimated settlements and final determinations are reflected as an increase or a reduction toin revenue in the period when such final determinations are known.

Historically these differences have been immaterial, and the Company has not had to go back and reassess the adjustments of future periods for past billing adjustments.

The Company frequently receives refund requests from insurance providers relating to specific patientsmonitors the variability and dates of service. Billing and reimbursement disputes are very commonuncertain timing over third-party payer types in the Company’s industry. These requests are sometimes related to a limited number of patients or products; at other times, they include a significant number of refund claims in a single request. The Company reviews and evaluates these requests and determines if any refund request is appropriate. The Company also reviews these refund claims when it is rebilling or pursuing reimbursement from insurance providers. The Company frequently has significant offsets against such refund requests, and sometimes amounts are due to the Company in excess of the amounts of refunds requested by the insurance providers. Therefore, at the time of receipt of such refund requests, the Company is generally unable to determine if a refund request is valid and should be accrued. Such refunds are recorded when the amount is fixed and determinable, however management maintains an allowance for estimated future refunds which we believe is sufficient to cover future claims.

However, no assurances can be given with respect to such estimates of reimbursements and offsets or the ultimate outcome of any refund requests. In addition to the allowance for billing adjustments, the Company records an allowance for uncollectible accounts receivable for wholesale (sales to distributors) sales and certain patient billings when necessary. Uncollectible accounts receivable are primarily a result of non-payment from patients who have been direct billed for co-payments or deductibles, lack of appropriate insurance coverage and disallowances of charges by Third-party Payors.our portfolios. If there is a change in our third-party payer mix over time, it could affect our net revenue and related receivables. We believe we have a sufficient history of collection experience to estimate the net collectible amounts by third-party payer type. However, changes to constraints related to billing adjustments and refund requests have historically fluctuated and may continue to fluctuate significantly from quarter to quarter and year to year.

During the quarter ended December 31, 2023, the Company had a material insurance provider contract or policy, application by a provider, a declinechange in the economic condition of providers or a significant turnover of Company billing personnel resulting in diminished collection effectiveness, the estimate of uncollectable receivables. The result of this change in allowance was a reduction of $6.2 million to net revenue ($4.6 million net of tax) or $0.14 per basic and diluted share for the allowance for uncollectible accounts receivable may not be adequate and may result in an increase in the future.

As ofthree months ended December 31, 2017,2023, and $0.13 per basic and diluted share for the Company believes its accounts receivable is reasonably stated at its net realizable / collectible value and has an adequate allowance for billing adjustments relating to all known insurance disputes and refund requests.

Deferred Insurance Reimbursement

During the first quarter of 2016, the Company collected $880,000 from a single insurance company for accounts receivable. The accounts receivable had been previously reduced to zero by the allowance for billing adjustments. Subsequent to March 31, 2016, the insurance company verbally communicated to the Company that this payment was made in error and requested it be refunded to the insurance company. The Company recorded this $880,000 insurance reimbursement as a deferred insurance liability. However, the Company is disputing the refund request and has initiated an internal review of the reimbursement to determine that the original sales arrangement was properly executed, the products had been delivered and title was transferred, the price of the products or services and the reimbursement rate is fixed and determinable, and the Company’s ultimate claim to the reimbursement is reasonably assured. The Company expects to record the appropriate amount as net revenue when such internal review is complete and the Company’s claim to the amount is reasonably assured. No further communication has been received from the insurance company regarding the payment or requested refund.

Inventory

Inventory, which primarily represents finished goods, are valued at the lower of cost (average) or market.

The Company monitors inventory for turnover and obsolescence and records losses for excess and obsolete inventory, as appropriate. The Company provides reserves for estimated excess and obsolete inventories equal to the difference between the costs of inventories on hand and the estimated market value based upon assumptions about future demand. If future demand is less favorable than currently projected by management, additional inventory write-downs may be required.

31

Finished goods at December 31, 2017 and 2016 includes products (finished goods, parts and supplies) held at the Company’s headquarters. During 2016 the Company ramped up the EZ Rx Prescribe program, whereby the NexWave electrotherapy device is sold by prescription and is shipped from the Company manufacturing facilities. During 2016 the EZ Rx Prescription program represented nearly 100% of orders. As a result, the Company is no longer holding substantial field inventory at different locations by healthcare or third party providers. Total gross inventories at December 31, 2017 was $0.4 million which was comprised of finished goods, work in process and parts and supplies as compared to December 31, 2016 of $0.1 million.

On December 31, 2017, the Company did not have open material inventory purchase commitments with vendors.

Stock-basedStock-based Compensation Compensation

The Company accounts for stock-based compensation through recognition of the cost of employee services received in exchange for an award of equity instruments, which is measured based on the grant date fair value of the award that is ultimately expected to vest during the period. The stock-based compensation expenses are recognized over the period during which an employee is required to provide service in exchange for the award (the requisite service period, which in the Company’s case is the same as the vesting period). For awards subject to the achievement of performance metrics, stock-based compensation expense is recognized when it becomes probable that the performance conditions will be achieved.

Income Taxes

Significant judgment is required in determining our provision for income taxes. We assess the likelihood that our deferred tax asset will be recovered from future taxable income, and to the extent we believe that recovery is not likely, we establish a valuation allowance. We consider future taxable income projections, historical results and ongoing tax planning strategies in assessing the recoverability of deferred tax assets. However, adjustments could be required in the future if we determine that the amount to be realized is less or greater than the amount that we recorded. Such adjustments, if any, could have a material impact on our results of our operations.

39

We use a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities.

The Inflation Reduction Act (“IRA”) was enacted into law on August 16, 2022. Included in the IRA was a provision to implement a 15% corporate alternative minimum tax on corporations whose average annual adjusted financial statement income during the most recently completed three-year period exceeds $1 billion. This provision is effective for tax years beginning after December 31, 2022. The IRA did not have a material impact on our reported results, cash flows or financial position during the year ended December 31, 2023.

Acquisition Method of Accounting for Business Combinations

We allocate the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase price over these fair values is recorded as goodwill. We engage independent third-party valuation specialists to assist us in determining the fair values of certain assets acquired and liabilities assumed. Such valuation require management to make significant estimates and assumptions, especially with respect to intangible assets. Different valuations approaches are used to value different types of intangible assets. Under the income approach, the relief from royalty method is a valuation technique which is used to estimate the value of certain intangible assets. This method utilizes projected financial information and hypothetical royalty rates to estimate the cost savings associated with asset ownership. The estimated cost savings are discounted for risk and the time value of money to estimate an intangible asset’s fair value. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable. If we do not achieve the results reflected in the assumptions and estimates, our goodwill impairment evaluations could be adversely affected, and we may impair a portion or all of our intangible assets, which would adversely affect our operating results in the period of impairment.

Impairment of Long-lived Assets, Including Goodwill

We assess impairment of goodwill annually and other long-lived assets when events or changes in circumstances indicates that their carrying value amount may not be recoverable. Long-lived assets consist of property and equipment, net and goodwill and intangible assets. Circumstances which could trigger a review include, but are not limited to: (i) significant decreases in the market price of the asset; (ii) significant adverse changes in the business climate or legal or regulatory factors; (iii) or expectations that the asset will more likely than not be sold or disposed of significantly before the end of its estimated useful life. If the estimated future undiscounted cash flows, excluding interest charges, from the use of an asset are less than the carrying value, a write-down would be recorded to reduce the related asset to its estimated fair value.

Contingent Considerations

We classified contingent consideration liabilities related to business acquisitions within Level 3 as factors used to develop the estimated fair value were unobservable inputs that are not supported by market activity. We estimated the fair value of contingent consideration liabilities using a Monte Carlo simulation which is based on equity volatility, the risk-free rate, the normal variate, projected milestone dates, discount rates, and probabilities of payment.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures.procedures    We maintain

Our management, including our Chief Executive Officer and Chief Financial Officer, have evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934), as amended, or the Exchange Act, as of December 31, 2023. Based on management’s review, with participation of our Chief Executive Officer and Chief Financial Officer, the Chief Executive Officer and Chief Financial Officer have concluded that, as of the quarter ended December 31, 2023, our disclosure controls and procedures were not effective due to the material weakness in internal control over financial reporting as described below. The term “disclosure controls and procedures,” as such term is defined in RuleRules 13a-15(e) and 15d-15(f)15d-15(e) under the Securities Exchange Act of 1934, (the “Exchange Act”),as amended, or the Exchange Act, means controls and other procedures of a company that are designed to provide reasonable assuranceensure that information required to be disclosed by usa company in the reports that we fileit files or submitsubmits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange CommissionCommission’s rules and forms,forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information required to be disclosed by a 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 person performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Management’s report on internal control over financial reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(e) of the Exchange Act). Management, with the participation of our Chief Executive Officer and Chief Financial Officer, has assessed the effectiveness of internal control over financial reporting as of December 31, 2023, based upon the framework in Internal Control- Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO. 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 Company’s annual or interim financial statements will not be prevented or detected on a timely basis. Based upon this evaluation and the material weakness identified below, our management concluded that our internal control over financial reporting was not effective as of December 31, 2023.

Material Weakness in Internal Control

We identified a material weakness related to Information Technology General Controls (“ITGCs”) that were not designed and operating effectively to ensure (i) appropriate segregation of duties was in place to perform program changes and (ii) the activities of individuals with access to modify data and make program changes were appropriately monitored. Business process controls (automated and manual) that are dependent on the affected ITGCs were also deemed ineffective because they could have been adversely impacted. We also identified a material weakness in the design and operating effectiveness around the valuation of certain accounts receivables.

The material weaknesses identified above did not result in any material misstatements in our financial statements or disclosures, and there were no changes to previously released financial results. Our management concluded that the consolidated financial statements included in this Annual Report on Form 10-K, present fairly, in all material respects, our financial position, results of operations, and cash flows for the periods presented in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP.

The effectiveness of our internal control over financial reporting as of December 31, 2023, has been audited by Marcum LLP as stated in their report, which is included in Item 8 of this Annual Report on Form 10-K.

41

Remediation Plan

Our management is committed to maintaining a strong internal control environment. In response to the identified material weakness above, management will take comprehensive actions to remediate the material weakness in internal control over financial reporting. We are in the process of developing and implementing remediation plans to address the material weakness described above.

Changes in Internal Control over Financial Reporting

Except for the items referred to above, there were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Inherent Limitation on the Effectiveness of Internal Control

Our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation of the Chief Executive Officer and the Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K.  Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concludeddo not expect that our disclosure controls and procedures were effective as of the end of such period.

32

In designingor our internal control over financial reporting will prevent all errors and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures,all fraud. A control system, no matter how well conceiveddesigned and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosurecontrol system will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and procedures are met.instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, in designing disclosure controls and procedures, we are required to apply judgment in evaluatingcan be circumvented by the cost-benefit relationshipindividual acts of possible disclosure controls and procedures.some persons, by collusion of two or more people or by management override of the controls. The design of any disclosuresystem of controls and proceduresis also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Management’s report on internal controlconditions; over financial reporting.Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is definedtime, controls may become inadequate because of changes in Exchange Act Rule 13a-15(f). All internal control systems, no matter how well designed, haveconditions, or the degree of compliance with policies or procedures may deteriorate. Due to inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the 2013 framework set forthlimitations in the report entitled Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). The COSO framework summarizes each of the components of a company’s internalcost-effective control system, including (i) the control environment, (ii) risk assessment, (iii) control activities, (iv) informationmisstatements due to error or fraud may occur and communication, and (v) monitoring.not be detected.

Based on our evaluation under the framework in Internal Control — Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2017.

As a result of our assessment of internal controls over financial reporting as of December 31, 2016, management had identified the following control deficiencies that represent material weaknesses that were remediated:

·The design and operating effectiveness of the Company’s controls over the financial statement close process related to the timely account reconciliation, analysis and assessment of key accounting estimates and financial reporting and disclosure was not in place. This was directly impacted by a limitation on current accounting resources and staffing resulting in limited capabilities for us to conduct independent reviews over the preparation of the related work product. Management identified remediation efforts which have been implemented during the second and third quarter of 2017. We have put policies and procedures in place plus made some key hires in the finance and accounting area and due to these actions, we believe we have fully remediated this deficiency as of September 30, 2017.

·We had a material weakness due to lack of segregation of duties. From October 2015 through May 2017, we had no Chief Financial Officer and our President and Chief Executive Officer assumed the role of Principal Financial Officer, in addition to that of Principal Executive Officer. This one person is also involved in the processing of banking transactions, has overall supervision and review of all cash disbursements and cash receipts, and had responsibility for the overall accounting and approval process. We hired a Chief Financial Officer on June 5, 2017 who will also serve as our Principal Financial Officer. Currently, all financial responsibilities are being managed by Chief Financial Officer and his staff and therefore we believe this material weakness was remediated as of December 31, 2017.

·We previously lacked independent Board members necessary to maintain audit and other board committees consistent with best practice corporate governance standards. On January 10, 2018, we appointed two independent directors, Messrs. Barry D. Michaels and Michael Cress. Mr. Michaels will also serve as chairman of the audit committee. Mr. Cress will also serve on the audit committee. The newly appointed Board members will review the Company’s results of operations for the year ended December 31, 2017 and the related Annual Report on Form 10-K.

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our independent registered public accounting firm pursuant to rules of the Securities and Exchange Commission that permit us to provide only management’s report in this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

During the quarter ended December 31, 2017, we completed our corrective action related to our segregation of duties. Our CFO and his staff have assumed all of the financial responsibility in the organization. We also completed the documentation of our internal control processes with our independent consulting firm. Although our newly appointed Board members were added subsequent to December 31, 2017, they will be involved in review of our 2017 year-end results and governance processes.

During the quarter ended September 30, 2017, our new Chief Financial Officer has assumed responsibility for all Company assets and control processes. The Company also retained an outside independent consulting firm which is updating our documentation of controls and performing testing as needed.

During the quarter ended June 30, 2017, we hired a new Chief Financial Officer and implemented certain financial controls related to financial statement close and reporting process.

Committees of the Board of Directors

Since our common stock is currentlyquoted on the OTCQB we are not subject to the corporate governance rules of listed companies. Accordingly we are not required to have independent board members or board committees. Nevertheless, our Board of Directors consists of two independent directors and our Board of Directors has established an Audit Committee, as described below.

Controlled Company Status

Our President and Chief Executive Officer, Thomas Sandgaard, beneficially owns approximately 53% of our outstanding common stock as of February 22, 2018. As a result, we are a “controlled company” within the meaning of Nasdaq and NYSE MKT corporate governance standards. Although no assurances canwill be made that we currently qualify or will qualify to be listed on a national exchange or that we will seek to do so, if we were to be approved to be listed on an exchange we could seek to meet the corporate governance standards of such exchange using certain exemptions applicable to controlled companies.

Under the Nasdaq rules, a company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company”, and if we are listed on Nasdaq, although there can be no assurances that we could or would seek to be listed, we expect to utilize exemptions relating to certain Nasdaq corporate governance requirements, including:

The requirement that we have a Nominating Committee that is composed entirely of independent;

The requirement that we have a Compensation Committee that is composed entirely of independent directors; and

The requirement for an annual performance evaluation of the Nominating and Compensation Committees.

The NYSE MKT has similar rules and exemptions with respect to controlled companies, which we expect to utilize if we are listed on the NYSE MKT, although there can be no assurances that we could or would seek to be listed. As a result of these exemptions, we anticipate that, if we are still a controlled company at the time that we apply to be listed on the Nasdaq or the NYSE MKT, our Nominating and Compensation Committees will not consist entirely of independent directors and that we will not be required to have an annual performance evaluation of the Nominating and Compensation Committees.

Audit Committee

The Audit Committee assists the Board of Directors in its oversight of the integrity of the Company’s accounting, auditing, and reporting practices. The Audit Committee meets with our independent registered public accounting firm at least annually to review the results of the annual audit and discuss the financial statements. The Committee will meet with our independent registered public accounting firm quarterly to discuss the results of the accountants’ quarterly reviews as well as quarterly results and quarterly earnings releases; recommends to the Board the registered public accounting firm to be retained; and receives and considers the accountants’ comments as to internal controls and procedures in connection with audit and financial controls. The Audit Committee reviews all financial reports prior to filingfiled with the Securities and Exchange Commission (“SEC”) and reviews all financial press releases prior to release. The specific responsibilitiesnot later than 120 days after the end of our fiscal year ended December 31, 2023 in carrying outconnection with the Audit Committee’s oversight role are set forth in the Audit Committee’s Charter, a copysolicitation of which is posted onproxies for the Company’s website, www.zynex.com, under "Investors — Corporate Governance." The Audit Committee currently consists2024 annual meeting of Messrs. Michaelsstockholders and Cress, each of whom are independent directors as required under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), Section 10A(m)(3). The Board of Directors has determined that Mr. Michaels is an "audit committee financial expert" as definedincorporated herein by the rules of the Securities and Exchange Commission.reference.

Director Nominations by Shareholders

We do not have procedures by which a security holder may recommend director nominees to our Board of Directors.

The Company Has Never Held A Stockholders’ Meeting and Has No Plans To Do So

We have never held a stockholders’ meeting and do not have plans to hold a meeting in 2018 unless we are required to hold such a meeting if we become listed on the Nasdaq or the NYSE MKT.

Code of Ethics

The Board has adopted a written code of ethics for each employee, including our Chief Executive Officer and Chief Financial Officer. The code also applies to our agents and representatives, sales representatives and consultants. The code of ethics is posted on our website at www.zynex.com.

Involvement in Certain Legal Proceedings

During the past ten years, none of the persons serving as executive officers and/or directors of the Company has been the subject matter of any of the following legal proceedings that are required to be disclosed pursuant to Item 401(f) of Regulation S-K including:  (a) any bankruptcy petition filed by or against any business of which such person was a general partner or executive officer either at the time of the bankruptcy or within two years prior to that time; (b) any criminal convictions; (c) any order, judgment, or decree permanently or temporarily enjoining, barring, suspending or otherwise limiting his involvement in any type of business, securities or banking activities; (d) any finding by a court, the SEC or the CFTC to have violated a federal or state securities or commodities law, any law or regulation respecting financial institutions or insurance companies, or any law or regulation prohibiting mail or wire fraud; or (e) any sanction or order of any self-regulatory organization or registered entity or equivalent exchange, association or entity.  Further, no such legal proceedings are believed to be contemplated by governmental authorities against any director or executive officer.

ITEM 11. EXECUTIVE COMPENSATION

Executive Compensation Objectives and Practices

We designed our executive officer compensation program to attract, motivate and retain key executives who drive our success. We strive to have pay reflect our performance and alignThe information required by this item will be included in the Proxy Statement, which will be filed with the interests of long-term stockholders, which we achieve with compensation that:

·Provides executives with competitive compensation that maintains a balance between cash and stock compensation, encouraging our executive officers to act as owners with an equity stake in our company;

·Enhances retention by having equity compensation subject to multi-year vesting; and

·Does not encourage unnecessary and excessive risk taking.

The Company evaluates both performanceSecurities and compensation to ensureExchange Commission not later than 120 days after the Company maintains its ability to attract and retain superior employees in key positions and compensation provided to key employee’s remains competitive relative to the compensation paid to similarly situated executives of other companies our size.

Elements of Executive Compensation

Our compensation for senior executive officers may consist of the following elements:base salary; incentive compensation; long-term equity compensation in the form of stock options and restricted stock; and employee benefits that are generally available to all our employees.

Base Salary

The Company provides named executive officers and other employees with base salary to compensate them for services rendered during the fiscal year. It is our policy to set base salary levels taking into account a number of factors, such as annual revenue, the natureend of our business, the structure of other companies’ compensation programs and the availability of compensation information. When setting base salary levels, in a manner consistent with the objectives outlined above, the Company considers our performance, the individual’s breadth of knowledge and performance and levels of responsibility.

Incentive Compensation

Our performance-based incentive compensation program is designed to compensate executives when financial performance goals are achieved. Executives have the opportunity to earn incentive compensation on an annual basis. Mr. Moorhead has an annual incentive compensation target of $100,000 for which the performance objectives are currently in the process of being finalized.

Long-Term Incentive Compensation – Equity Compensation

Our executive officers are eligible for stock awards. We believe that stock awards give executives a significant, long-term interest in our success, help retain key executives in a competitive market, and align executive interests with stockholder interests and long-term performance of the Company. We have granted options as well as restricted stock under our 2017 Stock Incentive Plan and predecessor plans. Stock awards also provide each individual with an added incentive to manage the Company from the perspective of an owner with an equity stake in the business. Moreover, the long-term vesting schedule (which is generally four years for employees and three years for non-employee directors, although this may vary at the discretion of the Company) encourages a long-term commitment to the Company by our executive officers and other participants.

Report of Independent Registered Public Accounting Firm on Internal Control Over Financial Reporting

To the Shareholders and Board of Directors of

Zynex, Inc.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMAdverse Opinion on Internal Control over Financial Reporting

We have audited Zynex, Inc.’s (the "Company") internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, because of the effect of the material weaknesses described in the following paragraph on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

A material weakness is a control deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in “Management's Annual Report on Internal Control Over Financial Reporting”:

It was determined that as of December 31, 2023, the Company's primary change management controls were not designed and implemented effectively to ensure IT program and data changes affecting the Company’s financial IT applications and underlying accounting records, are identified, tested, authorized and implemented appropriately to validate that data produced by its relevant IT system(s) were complete and accurate Other Information Technology General Controls, automated process-level controls, and manual controls that are dependent upon the information derived from such financially relevant systems were also determined to be ineffective as a result of such deficiency. Business process controls (automated and manual) that are dependent on the affected ITGCs were also deemed ineffective because they could have been adversely impacted;

Ineffective design and implementation of controls over the valuation of accounts receivable to properly address the risk of material misstatement.

These material weaknesses were considered in determining the nature, timing and extent of audit tests applied in our audit of the fiscal December 31, 2023 consolidated financial statements, and this report does not affect our report dated March 12, 2024 on those consolidated financial statements.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets as of December 31, 2023 and 2022, the related consolidated statements of operations, changes in shareholders’ equity, and cash flows for each of the two years in the period ended December 31, 2023, and related notes of the Company, and our report dated March 12, 2024 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying "Management Annual Report on Internal Control Over Financial Reporting". Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing

F-1

the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A 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 generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that degree of compliance with the policies or procedures may deteriorate.

We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB")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.

Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.

We believe that our audits provide a reasonable basis for our opinion.

The Company’s revenue is derived from sales and leases of electrotherapy devices and sales of related supplies and complementary products. The Company recognizes revenue when control of the product has been transferred to the patient, in the amount that reflects

F-3

the consideration the Company expects to receive. The Company estimates revenues using the portfolio approach based upon historical rates of collection, aging of receivables, product mix, trends in historical reimbursement rates by third-party payer types, and current relationships and experience with the third-party payers, which includes estimated variable consideration and relevant constraints for third-party payer refund requests, deductions and adjustments.

We identified the Company's estimation of transaction price related to variable consideration for revenue recognition, including the related valuation of accounts receivable, as a critical audit matter. Auditing the Company's determination of variable consideration and the related constraint for revenue recognition including the recorded value for accounts receivable was challenging and complex due to the high degree of subjectivity involved in evaluating management’s estimates. This required a high degree of auditor judgment and increased extent of effort to audit and evaluate management’s key judgments.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to revenue recognition and accounts receivable include the following, among others:

We performed testing throughout the year on a sample of contracts to test the validity of sales transactions and cash receipts application.
We evaluated the significant assumptions and the accuracy and completeness of the underlying data used in management’s calculations, including evaluating management’s estimate of historical reimbursement experience as well as expected future payment behavior through a combination of underlying data validation by inspection of source documents, independent recalculation of management’s analysis, review of correspondence with third-party payers, inquiries with management and evaluation of trends in collection rates and refund requests.

During 2016, the Company generated net income during Q3 and Q4 and combined with the profitability in 2017, the Company has recorded six consecutive profitable quarters, paid off its line of credit with Triumph Healthcare Finance, a division of TBK Bank, SSB, formerly known as Triumph Community Bank, (“Triumph”) (Note 9) and generated cash reserves and positive working capital.

In accordance with Accounting Standards Codification (“ASC”) 205-40, Presentation of Financial Statements – Going Concern, as of December 31, 2017, management evaluated whether there are conditions and events that raise doubt about the entity’s ability to continue as a going concern and concluded there is not significant doubt. The Company is currently able to meet its obligationsdeclared a 10% stock dividend on November 9, 2021, which was effective on January 21, 2022.

Reclassifications

Certain reclassifications have been made to the 2016 financial statements to conform to the consolidated 2017 financial statement presentation. These reclassifications had no effect on net earnings or cash flows as previously reported.

Use of Estimates

Preparation of financial statements in conformity with U.S. GAAPgenerally accepted accounting principles in the United States of America (“GAAP”), requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The most significant management estimates used in the preparation of the accompanying consolidated financial statements are associated with the allowance for billing adjustments and uncollectibleexpected net collectable value of its accounts receivable the reserve for obsolete, excess and damagedrelated revenue, inventory reserves, the life of its rented equipment, valuation ofleased unit devices, stock-based compensation, and valuation of long-lived assets acquired in business combinations, valuation of contingent consideration, and realizability of deferred tax assets.

Revenue Recognition, Accounts Receivable, Allowance for Billing Adjustments and Collectability

The Company recognizes revenue when each of the following four conditions are met: 1) a contract or sales arrangement exists, 2) products have been delivered and title has transferred 3) the price of the products or services is fixed or determinable, and 4) collectability is reasonably assured. The Company recognizes revenue for medical units and supplies when we receive notice that the product has been prescribed and delivered to the patient. The Company, prior to recognizing revenue verifies the patient’s insurance coverage or obtains the insurance company preauthorization, when required. Revenue from supplies is recognized upon delivery. Revenue from sales to distributors is recognized when the Company receives notice of receipt by the distributor. Revenue is reported net, after adjustments for estimated insurance company or governmental agency (collectively “Third-party Payors”) reimbursement deductions and, for wholesale customers and patient billings, an allowance for uncollectible accounts. The Third-party Payor reimbursement deductions are known throughout the health care industry as “billing adjustments” whereby the Third-party Payors unilaterally reduce the amount they reimburse for the Company’s products.

A significant portion of the Company’s revenues are derived, and the related receivables are due, from Third-party Payors. The nature of these receivables within the medical industry has typically resulted in long collection cycles. The process of determining what products will be reimbursed by Third-party Payors and the amounts that they will reimburse is complex and depends on conditions and procedures that vary among providers and may change from time to time. The Company maintains an allowance for billing adjustments and if necessary, an allowance for doubtful accounts. Billing adjustments result from reimbursements from Third-party Payors that are less than amounts claimed and from where the amount claimed by the Company exceeds the Third-party Payors usual, customary and reasonable reimbursement rate. The Company determines the amount of the allowance and adjusts it at the end of each reporting period, based on a number of factors, including historical rates of collection, the aging of the receivables, trends in the historical rates of collection and current relationships and experience with the Third-party Payors. If the rates of collection of past-due receivables recorded for previous fiscal periods changes, or if there is a trend in the rates of collection on those receivables, the Company may be required to change the rate at which it provides for additions to the allowance. A change in the rates of the Company’s collections can result from a number of factors, including experience and training of billing personnel, changes in the reimbursement policies or practices of Third-party Payors, or changes in industry rates of reimbursement. We believe we have a sufficient history of collection experience to estimate the net collectible amounts by payor. However, changes to the allowance for billing adjustments and uncollectible accounts, which are recorded as a reduction of revenue, have historically fluctuated and may continue to fluctuate significantly from quarter to quarter and year to year.

Due to the nature of the medical industry and the reimbursement environment in which the Company operates, estimates are required to record net revenues and accounts receivable at their net realizable values (also known as net collectible value). Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically, the complexity of third-party billing arrangements and the uncertainty of reimbursement amounts for certain products or services from payors or unanticipated requirements to refund payments previously received may result in adjustments to amounts originally recorded. Due to continuing changes in the health care industry and third-party reimbursement, as well as changes in our billing practices to increase cash collections, it is possible that management’s estimates could change in the near term, which could have an impact on our results of operations and cash flows. Any differences between estimated settlements and final determinations are reflected as an increase or a reduction to revenue in the period when such final determinations are known.

The Company frequently receives refund requests from insurance providers relating to specific patients and dates of service. Billing and reimbursement disputes are very common in the Company’s industry. These requests are sometimes related to a limited number of patients or products; at other times, they include a significant number of refund claims in a single request. The Company reviews and evaluates these requests and determines if any refund request is appropriate. The Company also reviews these refund claims when it is rebilling or pursuing reimbursement from insurance providers. The Company frequently has offsets against such refund requests, and sometimes amounts are due to the Company in excess of the amounts of refunds requested by the insurance providers. Therefore, at the time of receipt of such refund requests, the Company is generally unable to determine if a refund request is valid. The Company maintains an allowance for estimated future refunds which management believes is sufficient to cover future requests for refunds.

However, no assurances can be given with respect to such estimates of reimbursements and offsets or the ultimate outcome of any refund requests. In addition to the allowance for billing adjustments, the Company records an allowance for uncollectible accounts receivable for wholesale (sales to distributors) sales and certain patient billings when necessary. Uncollectible accounts receivable are primarily a result of non-payment from patients who have been direct billed for co-payments or deductibles, lack of appropriate insurance coverage and disallowances of charges by Third-party Payors. If there is a change to a material insurance provider contract or policy, application by a provider, a decline in the economic condition of providers or a significant turnover of Company billing personnel resulting in diminished collection effectiveness, the estimate of the allowance for billing adjustments and uncollectible accounts receivable may not be adequate and may result in an increase in the future.

As of December 31, 2017, the Company believes its accounts receivable is reasonably stated at its net realizable / collectible value and has an adequate allowance for billing adjustments including all known and estimated insurance disputes and refund requests.

Fair Value of Financial Instruments

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

F-7

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 — Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

The Company’s financial instruments at December 31, 2017, include cash, accounts receivable, accounts payable, and income taxes, for which currentaccrued liabilities. The carrying amounts of financial instruments, including cash, accounts receivable, accounts payable, and accrued liabilities approximate their fair value due to their short-term nature.

The Company’s accounts receivables represent unconditional rights to consideration and are generated when a single insurance company for accounts receivable. The accounts receivable had been previously reducedpatient receives one of the Company’s devices, related supplies, or complementary products. In conjunction with fulfilling the Company’s obligation to zero by the allowance for billing adjustments. Subsequent to March 31, 2016, the insurance company verbally communicated todeliver a product, the Company that this payment was made in error and requested it be refunded tobills the insurance company. The Company recorded this $880,000 insurance reimbursement as a deferred insurance liability. However,patient’s third-party payer or the Company is disputingpatient. Billing adjustments represent the refund request and has initiated an internal review ofdifference between the reimbursement to determine that the original sales arrangement was properly executed, the products had been delivered and title was transferred, the price of the products or serviceslist prices and the reimbursement rate is fixedrates set by third-party payers, including Medicare, commercial payers, and determinable, andamounts billed directly to the patient.

The Company monitors inventory for turnover and obsolescence and records losses for excess and obsolete inventory, as appropriate. The Company provides reserves for estimated excess and obsolete inventories equal to the difference between the costs of inventories on hand and the estimated market value based upon assumptions about future demand. If future demand is less favorable than currently projected by management, additional inventory write-downs may be required.

Finished goods at December 31, 2017 and 2016 includes products (finished goods, parts and supplies) held at the Company’s headquarters. During 2016, the Company ramped up the EZ Rx Prescribe program, whereby the NexWave electrotherapy device is sold by prescription and is shipped from the Company manufacturing facilities. On December 31, 2017, the Company did not have open material inventory purchase commitments with vendors. 

Allowance for Doubtful AccountsLong-lived Assets

The Company estimates uncollectible amounts,records intangible assets based on estimated fair value on the date of acquisition. Long-lived assets consist of net property and equipment and intangible assets. The finite-lived intangible assets are patents and are amortized on a straight-line basis over the estimated lives of the assets.

The Company assesses impairment of long-lived assets when applicable,events or changes in circumstances indicate that their carrying value amount may not be recoverable. Circumstances which could trigger a review include but are not limited to: (i) significant decreases in the market price of the asset; (ii) significant adverse changes in the business climate or legal or regulatory factors; or (iii) expectations that the asset will more likely than not be sold or disposed of significantly before the end of its estimated useful life.

If the estimated future undiscounted cash flows, excluding interest charges, from the use of an asset are less than the carrying value, a write-down would be recorded to reduce the related asset to its estimated fair value.

Useful lives of finite-lived intangible assets by each asset category are summarized below:

Leases

The Company determines if an arrangement is a lease at inception or modification of a contract.

The Company recognizes finance and operating lease right-of-use assets and liabilities at the lease commencement date based on the estimated present value of the remaining lease payments over the lease term. For our finance leases, the Company uses the implicit rate to determine the present value of future lease payments. For our operating leases that do not provide an implicit rate, the Company uses incremental borrowing rates to determine the present value of future lease payments. The Company includes options to extend or terminate a lease in the lease term when it is reasonably certain to exercise such options. The Company recognizes leases with an initial term of 12 months or less as lease expense over the lease term, and those leases are not recorded on our Consolidated Balance Sheets. For additional information on our leases where the Company is the lessee, see Note 12 - Leases.

A significant portion of our device revenue is derived from patients who obtain our devices under month-to-month lease arrangements where the Company is the lessor. Revenue related to devices on lease is recognized in accordance with Accounting Standards Codification (“ASC”) 842, “Leases” (“ASC 842”). Using the guidance in ASC 842, we concluded our transactions should be accounted for as operating leases based on the following criteria:

The lease does not transfer ownership of the underlying asset to the lessee by the end of the lease term.
The lease does not grant the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise.
The lease term is month to month, which does not meet the major part of the remaining economic life of the underlying asset. However, if the commencement date falls at or near the end of the economic life of the underlying asset, this criterion shall not be used for purposes of classifying the lease.
There is no residual value guaranteed and the present value of the sum of the lease payments does not equal or exceed substantially all of the fair value of the underlying asset.
The underlying asset is expected to have alternative uses to the lessor at the end of the lease term.

Lease commencement occurs upon delivery of the device to the patient. The Company retains title to the leased device and those devices are classified as property and equipment on the balance sheet. Since our leases are month-to-month and can be returned by the patient at any time, revenue is recognized monthly for the duration of the period in which the patient retains the device.

Revenue Recognition

Revenue is derived from sales and leases of the Company’s electrotherapy devices and sales of related supplies and complementary products. Device sales can be in the form of a purchase or a lease. Supplies needed for the device can be set up as a recurring shipment or ordered through the customer support team or online store as needed. The Company recognizes revenue when control of the product has been transferred to the patient, in the amount that reflects the consideration the Company expects to receive. In general, revenue from sales of devices and supplies is recognized once the product is delivered to the patient, which is when control is deemed to have transferred to the patient.

Sales of devices and supplies are primarily shipped directly to the patient, with a small amount of revenue generated from sales to distributors. In the healthcare industry, there is often a third party involved that will pay on the patients’ behalf for purchased or leased devices and supplies. The terms of the separate arrangement impact certain aspects of the contracts, with patients covered by third party payers, such as contract type, performance obligations, and transaction price. For purposes of revenue recognition, the contract with the customer refers to the arrangement between the Company and the patient. The Company does not have any material deferred revenue in the normal course of business as each performance obligation is met upon delivery of goods to the patient. There are no substantial costs incurred through support or warranty obligations.

Revenues are estimated using the portfolio approach by third-party payer type based upon historical bad debts, current customer receivable balances, the agerates of customer receivable balances, the customer’s financial conditioncollection, aging of receivables, trends in historical reimbursement rates by third-party payer types, and current economic trends.relationships and experience with the third-party payers, which includes estimated constraints for third-party payer refund requests, deductions, allowance for uncollectible accounts and billing allowance adjustments. Inherent in these estimates is the risk they will have to be revised as additional information becomes available and constraints are released. If initial estimates are updated these changes are accounted for as increases or decreases in the transaction price. Assuming the underlying performance obligation to which the change in price relates has already been satisfied, those changes in transaction price are immediately recognized as increases or decreases in revenue (not credit losses (bad debt expense)) in the period in which the estimate changes. Additionally, the complexity of third-party payer billing arrangements, the uncertainty of reimbursement amounts for certain products from third-party payers, or unanticipated requirements to refund payments previously received may result in adjustments to amounts originally recorded. Settlements with third-party payers for retroactive revenue adjustments due to audits, reviews, or investigations are considered variable consideration and are included in the determination of the estimated transaction price using the expected amount method. These adjustments to transaction price are estimated based on the terms of the payment agreement with the payer, correspondence from the payer, and historical settlement activity, including an assessment to ensure that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the retroactive adjustment is subsequently resolved. Due to continuing changes in the healthcare industry and third-party payer reimbursement, it is possible the Company’s forecasting model to estimate collections could change, which could have an impact on the Company’s results of operations and cash flows. Any differences between estimated and actual collectability are reflected in the period in which payment is received.

The Company monitors the variability and uncertain timing over third-party payer types in the portfolios. If there is a change in the Company’s third-party payer mix over time, it could affect net revenue and related receivables. The Company believes it has a sufficient history of collection experience to estimate the net collectible amounts by third-party payer type. However, changes to constraints related to billing adjustments and refund requests have historically fluctuated and may continue to fluctuate significantly from quarter-to-quarter and year-to-year.

Goodwill

Goodwill is recorded as the difference between the fair value of the purchase consideration and the estimated fair value of the net identifiable tangible and intangible assets acquired.

Goodwill is not subject to amortization but is subject to impairment testing. The Company tests goodwill at least annually for impairment. The Company tests more frequently if indicators are present or changes in circumstances suggest that impairment may exist. These indicators include, among others, declines in sales, earnings, cash flows, or the development of a material adverse change in the business climate. The Company assesses goodwill for impairment at the reporting unit level. The estimates of fair value and the determination of reporting units requires management judgment.

Depreciation is computed using the straight-line method over the useful life of the asset ranging from three to seven years.

Repairs and maintenance costs are charged to expense as incurred.

Stock-based Compensation

The Company accounts for stock-based compensation through recognition of the cost of employee services received in exchange for an award of equity instruments, which is measured based on the grant date fair value of the award that is ultimately expected to vest during the period. The stock-based compensation expenses are recognized over the period during which an employee is required to provide service in exchange for the award (the requisite service period, which in the Company’s case is the same as the vesting period). For awards subject to the achievement of performance metrics, stock-based compensation expense is recognized when it becomes probable that the performance conditions will be achieved.

Recently Issued Accounting Standards Board (“FASB”) ASC 740-10, Income Taxes, which requires that the effect on deferred tax assets and liabilities of a change in tax rates be recognized in the period the tax rate change was enacted. Due to the complexities involved in accounting for the recently enacted Tax Act, the U.S. Securities and Exchange Commission’s Staff Accounting Bulletin (“SAB”) 118 requires that the Company include in its financial statements the reasonable estimate of the impact of the Tax Act on earnings to the extent such estimate has been determined.

Pursuant to the SAB118, the Company is allowed a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impacts. The final impact on the Company from the Tax Act’s transition tax legislation may differ from the aforementioned estimates due to the complexity of calculating and supporting with primary evidence such U.S. tax attributes such as accumulated foreign earnings and profits, foreign tax paid, and other tax components involved in foreign tax credit calculations for prior years back to 1998. Such differences could be material, due to, among other things, changes in interpretations of the Tax Act, future legislative action to address questions that arise because of the Tax Act, changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates the Company has utilized to calculate the transition tax's reasonable estimate. The Company will continue to evaluate the impact of the U.S. Tax Act and will record any resulting tax adjustments during 2018.

We are currently evaluating the impact of our pending adoption of ASU 2017-12 on our consolidated financial statements.

In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) ("ASU 2016-13"), Measurement of Credit Losses on Financial Instruments. The standard significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren't measured at fair value through net income. The standard will replace today's "incurred loss" approach with an "expected loss" model for instruments measured at amortized cost. For available-for-sale debt securities, entities will be required to record allowances rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. It also simplifies the accounting model for purchased credit-impaired debt securities and loans.

In May 2014, the FASB issued ASU No. 2014-09—“Revenue from Contracts with Customers” (Topic 606) which amended revenue recognition guidance to clarify the principles for recognizing revenue from contracts with customers. The guidance requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amountimpact that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The guidance also requires expanded disclosures relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract.  This accounting guidance is effective for the Company beginning in the first quarter of fiscal year 2018, using one of two prescribed retrospective methods. We will adopt the new standard effective January 1, 2018, using the modified retrospective transition method. We finalized our analysis and the adoption of this guidancestandard will not have a material impact on ourits consolidated financial statementsstatements.

(3)   BUSINESS COMBINATIONS

On December 22, 2021, the Company and our internal controls over financial reporting.its wholly-owned subsidiary Zynex Monitoring Solutions, Inc., entered into a Stock Purchase Agreement (the “Agreement”) with Kestrel and each of the shareholders of Kestrel (collectively, the “Selling Shareholders”). Under the Agreement, the Selling Shareholders agreed to sell all of the outstanding common stock of Kestrel (the “Kestrel Shares”) to the Company. The consideration for the Kestrel Shares consisted of $16.1 million cash and 1,467,785 shares of the Company’s common stock (the “Zynex Shares”). All of the Zynex Shares were subject to a lock-up agreement for a period of one year from the closing date under the Agreement (the “Closing Date”). The Agreement provides the Selling Shareholders with piggyback registration rights. 978,524 of the Zynex Shares were deposited in escrow (the “Escrow Shares”). The number of Escrow Shares were subject to adjustment on the one-year anniversary of the Closing Date (or in connection with any Liquidation Event (as defined in the Agreement) that occurs prior to such anniversary date) based on the number of shares equal to $10.0 million divided by a 30-day volume weighted average closing price of the Company’s common stock. The Escrow Shares were adjusted on the anniversary date, which resulted in the cancellation of 156,673 Escrow Shares. Half of the Escrow Shares were to be released on submission of a dossier on a laser-based photoplethysmographic device (the “Device”) to the FDA for permission to market and sell the Device in the United States. The other half of the Escrow Shares were to be released upon determination by the FDA that the Device can be marketed and sold in the United States.

In October 2016,

On July 27, 2023, the FASB issued Accounting Standards Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers Other than Inventory (ASU 2016-16),Company, ZMS, Kestrel, and the Selling Shareholders, entered into an amendment to the Stock Purchase Agreement (the “Amendment”). The parties entered into the Amendment to modify certain terms of the Agreement related to the conditions to be satisfied for the release of the Escrow Shares to the Selling Shareholders. The Escrow Shares were released from escrow, and simultaneously, the selling stockholders entered into a lock-up agreement. The lock-up agreement includes two lock-up periods which requires companies to recognizerelease certain restrictions on the income-tax consequencesSelling Shareholders on December 31, 2023 and June 30, 2024, respectively.

The Escrow Shares are included in the Company’s calculation of an intra-entity transferbasic earnings per share for both years ended December 31, 2023 and 2022.

The acquisition of an asset other than inventory when the transfer occurs, rather than when the assetKestrel has been sold to an outside party. We will adopt the new standard effective January 1, 2018, using the modified retrospective transition approach throughaccounted for as a cumulative-effect adjustment to retained earningsbusiness combination under ASC 805 – “Business Combinations” (“ASC 805”). Under ASC 805, assets acquired, and liabilities assumed in a business combination must be recorded at their fair values as of the effectiveacquisition date. A cumulative-effect adjustment will capture the write-off of income tax consequences deferred from past intra-entity transfers involving assets other than inventory, new deferred tax assets, and other liabilities for amounts not currently recognized under U.S. GAAP. Based on transactions up to December 31, 2017, we do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18), which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the statement of cash flows. We will adopt the new standard effective January 1, 2018, using the retrospective transition approach for all periods presented. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (ASU 2017-01), which revises the definition of a business and provides new guidance in evaluating when a set of transferred assets and activities is a business. We will adopt the new standard effective January 1, 2018, on a prospective basis and do not expect the standard to have a material impact on our consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-04), which eliminates step two from the goodwill impairment test. Under ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value up to the amount of goodwill allocated to that reporting unit. This guidance will be effective for us in the first quarter of 2020 on a prospective basis, and early adoption is permitted. We do not expect the standard to have a material impact on our consolidated financial statements.

Management has evaluated other recently issued accounting pronouncements and does not believe that any of these pronouncements will have a material impact on the Company’s consolidated financial statements.

Basic earnings per share are computed by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding and the number of dilutive potential common share equivalents during the period, calculated using the treasury-stock method for outstanding stock options.

The Tax Act reduces the U.S. statutory corporate tax rate from 35% to 21% for our tax years beginning in 2018, which resulted in the

re-measurement of the federal portion of our deferred tax assets as of December 31, 2017 from 35% to the new 21% tax rate.

The Company has generated a net operating loss carryforward (NOL) for federal income tax purposes of approximately $2.9 million as of December 31, 2017, which is available to offset taxable income in the future at various dates through 2037. The company also has available NOL carryforwards of approximately $4.9 million for state purposes, which expire at various dates ranging from five to seven years.

As of December 31, 2017 and 2016, the Company has a valuation allowance of approximately $1.8 million and $5.7 million, respectively. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers past history, the scheduled reversal of deferred tax liabilities, available taxes in carryback periods, projected future taxable income projections and tax planning strategies in making this assessment. The Company has generated taxable income in 2017 and projects income in future periods. Based on these factors, the Company is currently evaluating the realization of its deferred tax assets and may have an adjustment to its valuation allowance in the future.

The accounting standard related to income taxes applies to all tax positions and defines the confidence level that a tax position must meet in order to be recognized in the financial statements. The accounting standard requires that the tax effects of a position be recognized only if it is "more-likely-than-not"“more-likely-than-not” to be sustained by the taxing authority as of the reporting date. If a tax position is not considered "more-likely-than-not"“more-likely-than-not” to be sustained, then no benefits of the position are to be recognized. Differences between financial and tax reporting which do not meet this threshold are required to be recorded as unrecognized tax benefits. This standard also provides guidance on the presentation of tax matters and the recognition of potential IRS interest and penalties. As of December 31, 20172023 and 2016,2022, the Company does not have an unrecognized tax liability.

The Company’s asset and 1.25% fees).liability classified financial instruments include cash, accounts receivable, accounts payable, accrued liabilities, and contingent consideration. The Triumph Agreement required monthly interest paymentscarrying amounts of financial instruments, including cash, accounts receivable, accounts payable, and accrued liabilities approximate their fair value due to their short maturities. The Company measures its long-term debt at fair value which approximates book value as the long-term debt bears market rates of interest. The fair value of acquisition-related contingent consideration is based on a Monte Carlo models. The valuation policies are determined by management, and the Company’s Board of Directors is informed of any policy change.

Authoritative guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in arrearsan orderly transaction between market participants at the measurement date. The guidance establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions of what market participants would use in pricing the asset or liability developed based on the first day of each month.best information available in the circumstances. The Triumph Agreement originally maturedhierarchy is broken down into three levels based on December 19, 2014. Triumph had agreed to forbear from the exercise of its rights and remedies under the termsreliability of the Triumph Agreement through June 30, 2017, pursuantinputs as follows:

Level I: Inputs that reflect unadjusted quoted prices in active markets that are accessible to Zynex for identical assets or liabilities;

Level II: Inputs include quoted prices for similar assets and liabilities in active or inactive markets or that are observable for the termsasset or liability either directly or indirectly; and

Level III: Unobservable inputs that are supported by little or no market activity.

The Company’s assets and liabilities, which are measured at fair value, on a recurring basis, are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. The Company’s policy is to recognize transfers in and/or out of fair value hierarchy as of the March 31, 2017 forbearance agreement. Indate in which the event or change in circumstances caused the transfer. The Company has consistently applied the valuation techniques discussed below in all periods presented.

The Company classified its contingent consideration liability in connection with the agreement entered intoacquisition of Kestrel within Level 3 as factors used to develop the estimated fair value are unobservable inputs that are not supported by market activity.
