Chronic pain is a significant public health problem. It is defined by the National Institutes of Health (NIH) as any pain lasting more than 12 weeks in contrast toweeks. This contrasts with acute pain which is a normal bodily response to injury or trauma. Chronic pain conditions include painful diabetic neuropathy, or PDN,low back pain, arthritis, fibromyalgia, sciatica, musculoskeletalneuropathic pain, cancer pain and many others. Chronic pain may be triggered by an injury or there may be an ongoing cause such as disease or illness. There may also be no clear cause. Pain signals continue to be transmitted in the nervous system over extended periods of time often leading to other health problems.


These can include fatigue, sleep disturbance, decreased appetite, and mood changes which cause difficulty in carrying out important activities and contributing to disability and despair. In general, chronic pain cannot be cured. Treatment of chronic pain is focused on reducing pain and improving function. The goal is effective pain management.


Chronic pain is widespread. It affects over 100 million adults in the United States and more than 1.5 billion people worldwide. The global market for pain management drugs and devices alone was valued at $35 billion in 2012. The estimated incremental impact of chronic pain on health care costs in the United States is over $250 billion per year and lost productivity is estimated to exceed $300 billion per year.

The most common approach to chronic pain management is pain medication. This includes over-the-counter drugs (such(OTC) internal and external analgesics as Advil and Motrin), andwell as prescription drugs including anti-convulsants (such as Lyrica and Neurontin) and anti-depressants (such as Cymbalta and Elavil). Topical creams may also be used (such as Zostrix and Bengay). With severe pain, narcotic pain medications, may be prescribed (such as codeine, fentanyl, morphine, and oxycodone).both non-opioid or opioid. The approach to treatment is individualized, drug combinations may be employed, and the results are often hit or miss. Side effects and the potential for addiction are real and the risks are substantial.

Increasingly, restrictions are being imposed on access to prescription opioids. Reflecting the complexity of chronic pain and the difficulty in treating, chronic pain, we believe that inadequate relief leads 25% to 50% of pain sufferers to turn to the over-the-counter market for supplements orseek alternatives to prescription pain medications. These alternatives include nutraceuticals, acupuncture, chiropractic care, non-prescription medications, topical creams, lotions,analgesics, electrical stimulators, dietary products, braces, sleeves, pads and other items. In total theythese pain relief products and services account for over $4approximately $20 billion in annual spending in the United States on pain relief products.

Non-invasive approaches to neuro-stimulation (transcutaneousinvolving transcutaneous electrical nerve stimulation or TENS)(TENS) have achieved limited efficacy in practice due to device limitations, ineffective dosing and low patient compliance.

adherence. Our Strategy

There are large and important unmet medical needs inQuell wearable technology for chronic pain treatment. Prescriptionaddresses these limitations and has demonstrated its efficacy in multiple clinical studies.


Diabetes is a worldwide epidemic with an estimated affected population of over 400 million people. Within the United States there are over 30 million people with diabetes and another 80 million with pre-diabetes. The annual direct cost of treating diabetes in the United States exceeds $100 billion. Although there are dangerous acute manifestations of diabetes, the primary burden of the disease is in its long-term complications which include cardiovascular disease, nerve disease and resulting conditions such as foot ulcers which may require amputation, eye disease leading to blindness, and kidney failure. The most common long-term complication of diabetes affecting over 50% of the diabetic population is nerve disease or diabetic neuropathy. Diabetic peripheral neuropathy (DPN) is the primary trigger for diabetic foot ulcers which may progress to the point of requiring amputation. People with diabetes have a 15-25% lifetime risk of foot ulcers and approximately 15% of foot ulcers lead to amputation. Foot ulcers are the most expensive complication of diabetes with a typical cost of $5,000 to $50,000 per episode. In addition, between 16% and 26% of people with diabetes suffer from chronic pain in the feet and lower legs.

Early detection of DPN is important because there are no treatment options once the nerves have degenerated. Today’s diagnostic methods for DPN range from a simple monofilament test for lack of sensory perception in the feet to a nerve conduction study performed by a specialist. Our DPNCheck technology provides a rapid, low cost, quantitative test for peripheral nerve disease, including DPN. It addresses an important medical need and is particularly effective in screening large populations likely susceptible to DPN. DPNCheck has been validated in numerous clinical studies.

Goals and Strategy

We believe that personalized neurostimulation to suppress pain can provide a valuable complement to pain medications and over-the-counter therapies are often inadequateother treatments. Our Quell technology addresses this important medical need and can lead to other health issues. We believe that controlled, personalized, neuro-stimulation to suppress pain provides an important complement to pain medications. As a medical device company with unique experience in designing devices to manage and alter peripheral nerve function, we believe we are welluniquely positioned to make neuro-stimulation widelyQuell available to chronic pain sufferers. We have direct experience with neuro-stimulation through our prescription SENSUS wearable pain management device which has been on the market for the past three years and Quell, our over-the-counter, or OTC, wearable device for pain relief which was launchedsufferers in the second quarterUnited States. We also recognize the worldwide need for an accurate, cost-effective technique to screen for diabetic peripheral neuropathy. Our DPNCheck technology was designed to address this specific need and is supported by an extensive body of 2015 and builds upon the core SENSUS neuro-stimulation technology.

Driving Profitable Growth with Key Proprietary Products.

Quell is an advanced, wearable device is lightweight andtechnology for treating chronic pain. It can be worn during the day while active and at night while sleeping. ItQuell is drug-free and has been cleared by the FDA for treatment of chronic intractable pain without a doctor’s prescription. UsersQuell has been shown in multiple clinical studies to relieve chronic pain and, in a published study, 4 out of 5 users reported improvement in chronic pain. Quell users can personalize and manage therapy discreetly via the Quell app. Quell also offers health tracking relevant to chronic pain sufferers including pain, sleep, activity, and gait. Quell users can synchronize their data with the Quell Health Cloud™, which provides customized feedback and powers one of the device have the option of using their smartphones to automatically track and personalize theirworld’s largest chronic pain therapy. Quell was launched through two distribution channels: a professional channel using a direct sales force to target podiatrists, pain physicians, primary care physicians, and chiropractors who resell the product, and a direct-to-consumer channel using online marketing and lead generation. After establishing the professional and direct to consumer channels, we expanded distribution to include Amazon e-commerce sales and QVC direct response TV, or DRTV, sales. We are developing other distribution channels for broader access to the retail markets. We believe there are significant opportunities to market Quell outside of the United States, particularly in Western Europe, Japan and China; however, we do not intend to approach those markets until we have established a solid presence in the United States.databases.
DPNCheck,our diagnostic test for peripheral neuropathies,
Quell was made commercially available in the fourth quarterUnited States in mid-2015. Quell product sales during 2018 totaled $10.5 million and cumulatively from launch have totaled $32.6 million. We have shipped over 180,000 Quell devices to customers. Quell is available via e-commerce on our QuellRelief website and Amazon, and at select retailers. We use television and digital promotion to expand brand awareness. In September 2018 we launched our next generation product Quell 2.0 with enhanced functionality. Quell 2.0 features a 50% reduction in device size and 20% increase in power capacity, an updated app with coaching, an intensive therapy option, and advanced personalization.

In 2018 we initiated several key efforts to improve profitability:
User experience - launched Quell 2.0 with improved usability
User engagement - implemented focused, continuing user outreach to improve aftermarket sales
Distribution - restructured channels to emphasize e-commerce, minimize higher cost retail and home shopping
Cost of goods - launched Quell 2.0 incorporating a design for manufacturing efficiency
Pricing - launched Quell 2.0 at higher price and with bundling, subscription option for consumables

DPNCheck is a fast, accurate, quantitative diagnostic test for peripheral neuropathies, including diabetic peripheral neuropathy.

DPNCheck was made commercially available in late 2011. DPNCheck revenues for the years December 31, 2015 and 2014 were approximately $2.3product sales in 2018 totaled $4.2 million and $1.8 million, respectively.over the past three years totaled $12.1 million. We have shipped nearly 5,000 devices to customers. Our USDPNCheck revenues are dominated by sales of high margin patient test biosensors. Our U.S. sales efforts focus on Medicare Advantage providers who assume financial responsibility and the associated risks for the health care costs of their patients. We believe that DPNCheck presents an attractive clinical case with early detection of neuropathy allowing for earlier clinical intervention to help mitigate the effects of neuropathy on both patient quality of life and cost of care. Also, the diagnosis and documentation of neuropathy provided by DPNCheck helps clarify the patient health profile which, in turn, may have a direct, positive effect on the Medicare Advantage premium received by the provider. DPNCheck is marketed in Japan by our distribution partner Fukuda Denshi; in China by OMRON Medical (Beijing) Ltd.; and in Mexico by Scienta Farma.

Research and Development Innovation for Competitive Advantage

Our products are proprietary and were developed in-house by our R&D team. We believe that attractive opportunities exist outsidecontinual product innovation, focusing in our unique competency of precision neurostimulation, is essential to profitable growth and to competitive advantage. In 2019 we will enter the United States including Japan where we received regulatory approvaljoint development phase of our GSK collaboration. Quell projects will constitute the majority of our R&D development efforts and launchedwill be prioritized and overseen by a joint steering committee of NeuroMetrix and GSK representatives. Quell projects will be jointly funded as part of the GSK collaboration. In addition, our R&D team will provide DPNCheck with our distribution partner Omron Healthcare in the third quarter of 2014; in China where we recently received regulatory approval and are working with Omron Healthcare toward commercial launch in the second half of 2016; and in Mexico where our distributor Scienta Farma received regulatory approval and initiated sales in the fourth quarter of 2015.

Maintaining a High Level of Research and Development Productivity Our researchengineering resources to address product maintenance and development or R&D, team successfully delivered Quell, an FDA cleared, technologically sophisticated, smart phone integrated product with electrodes and other accessories. We believe that there are no comparable products on the market. Our R&D team is now charged with maintaining and expanding this Quell competitive technological advantage, and enhancing our intellectual property position, through continuing innovation. We expect innovation to take the form of device and software enhancements to improve the user experience, expanded smart phone applications, and new electrode features to optimize therapy. Technological innovation will continue to be one of our top priorities.

SENSUS

The SENSUS pain therapy device, the technological predecessor to Quell, is a prescription neuro-stimulation device based on TENS for relief of chronic, intractable pain. SENSUS, which was commercially launched in the first quarter of 2013, is a convenient and wearable device that offers physicians and their patients a non-narcotic pain relief option as a complement to medications. SENSUS is comprised of: (1) an electronic device with a strap that is worn on the upper calf and (2) an electrode which attaches to the device. We provide prescribing physicians with PC-based software that links to the device via a USB connection, thereby allowing them to download a record of the patient’s use of the device. The SENSUS device and electrodes were cleared by the FDA for commercial distribution. When medically indicated and supported by proper documentation, TENS devices are generally reimbursed by Medicare and many commercial insurance companies under the DME benefit. We believe SENSUS will have a limited impact on future revenues. SENSUS customers have purchased approximately 10,000 devices through December 31, 2015.

Sales, Marketing, and Distribution


Quell was made commercially availableis distributed in the United States duringvia e-commerce including the second quarter of 2015. Initial distribution involved two channels: a professional channel using a direct sales forceCompany’s website www.quellrelief.com and Amazon, and via select retailers and health care professionals. We utilize television promotion and digital advertising to target podiatrists, pain physicians, primary care physicians, and chiropractors who stock and resell theexpand product and a direct-to-consumer channel using our e-commerce website supported by social media plus traditional marketing. After establishing the professional and direct to consumer channels we expanded distribution to include ecommerce on Amazon.com and DRTV sales on QVC. We plan to make Quell more broadly available through retail distribution in 2016. Marketing for Quell is led by our Senior Vice President and General Manager, Consumer with support from marketing staff and supplemented by outside consultants. We believe there are opportunities for Quell outside the United States, particularly in Western Europe, Japan and China; however, we do not plan to address those markets until we have established a solid presence in the United States.

SENSUS is sold through a combination of national and regional DME suppliers whose sales representatives call on endocrinologists, podiatrists, and primary care physicians that are challenged with trying to manage chronic pain in their patients, including patients with painful diabetic neuropathy. The efforts of DME suppliers are coordinated from our corporate office.

Research and Development


We believe that we have research and development (R&D) capability that is unique to the industry with nearlyover two decades of experience in developing diagnostic and therapeutic devices involving the precision stimulation and measurement of nerve signals for clinical purposes. This groupOur company has extensive experience in neurophysiology, biomedical instrumentation, signal processing, biomedical sensors, and information systems.

Our R&D team works closely with our marketing group and customers to design products that are focused on improving clinical outcomes. The team consists of ten people including two who hold M.D. degrees and three who hold Ph.D. degrees. It includes the extensive involvement of ourOur founder and Chief Executive Officer whois extensively involved with our R&D efforts. He holds both M.D. and Ph.D. degrees and who also coordinates the clinical programs that we support.

Quell Innovation.  Quell utilizes our proprietary wearable nerve stimulation technology to provide relief from chronic pain which can encompass lower back problems, fibromyalgia, arthritis, painful diabetic neuropathy and others. Quell is unique among OTC neurostimulation products in its clinical indications, technology, personalization and digital health features. While our R&D efforts to date have provided us first-to-market advantage, we anticipate that success will attract competition and that we must continually innovate to maintain a leadership position. Starting in 2019 our Quell development efforts will be overseen by a joint steering committee of NeuroMetrix and GSK representatives and will be co-funded by both NeuroMetrix and GSK. Also, we intend to continually strengthen our intellectual property position with the development of additional know-how and a growing body of patent applications.

We anticipate that success will attract competition and that we must continually innovate to maintain a leadership position. Accordingly, our R&D team is developing the next generation Quell to improve the user experience, optimize therapy, expand health tracking, and modify the electrodes to help ensure appropriate usage. Also, we are exploring new clinical indications such as restless leg syndrome. We intend to strengthen our intellectual property position with the development of additional know-how and a growing body of patent applications.
Support for DPNCheck.  DPNCheck is our quantitative nerve conduction test for peripheral neuropathies including DPN. Its usage is growing in the Medicare Advantage market in the United States and in Japan where it was launched in 2014. DPNCheck recently received regulatory approval in China and we are working with Omron Healthcare toward commercial launch in the second half of 2016. The characteristics of these markets often require device modification for local acceptance which, in turn, involves our R&D team. We are collaborating with Omron Healthcare in Asia for DPNCheck and anticipate continuing engineering support requirements.
Support clinical studies for our wearable technology.  We recently completed an independent post-market clinical study for Quell. Results were positive with 81% of subjects reporting an improvement in their chronic pain and overall health, and 67% reporting a reduction in their use of pain medications while using Quell. This study has been helpful to our marketing efforts and points to the need to continue to build the clinical foundation for Quell. During 2016 we intend to fund new clinical studies addressing the efficacy of our wearable technology.

Research

Cost of Goods Sold (COGS) Improvement.  We have identified specific opportunities to reduce Quell COGS, with both near-term and development expenses were approximately $3.9 million, $4.1 million,longer-term initiatives underway. Lower COGS would improve gross margins and $3.4 millionproduct profitability. The COGS initiatives involve R&D support as well as investment in engineering design and equipment.
Support for 2015, 2014,DPNCheck.  DPNCheck, our quantitative nerve conduction test for peripheral neuropathies including DPN, has experienced growing demand in the Medicare Advantage market in the United States, in Japan and 2013, respectively.

in Mexico. DPNCheck has regulatory clearance in China and is in the early stages of building the market. The characteristics of new markets often require device modification for local acceptance which, in turn, involves our R&D team.

Support clinical studies for our wearable technology.  Quell is an FDA-cleared Class 2 medical device. We plan to continue to build the body of evidence from clinical studies that is foundational to Quell credibility among health care professionals and supports our marketing efforts.

Clinical Program


Our clinical program operates under the direction of our Chief Executive Officer. This may from time-to-time be comprised of internal, collaborative, and external clinical studies. Internal clinical studies are designed and implemented directly by us for the purposes of product design and early clinical validation. Collaborative studies are conducted together with leading researchers around the world to provide clinical validation and to explore the clinical utility of our products. External studies are entirely independent of us, although in many cases the researchers request unrestricted grants for financial and/or material support, such as for devices and consumables. External studies may examine the clinical performance and utility of our products or our products may be used as outcomes measures. We actively seek to publish our clinical study results in leading peer-reviewed journals while also encouraging our clinical collaborators and clinical study grant recipients to do the same.

During


In a study published in 2016 in the third quarterJournal of 2015 we completedPain Research, 81% of subjects reported a general improvement in their chronic pain and 67% reported a reduction in pain medication use after 60 days of use of Quell. Additional study findings included decreased interference from pain with sleep and walking ability. Another study published in the Journal of Pain Research in 2017 examined changes in chronic pain outcomes following 60 days of Quell use. Study subjects reported statistically and clinically significant improvement in all pain outcomes and all pain outcomes exhibited a strong dose-response relationship. In particular, about 60% of subjects with high Quell therapy utilization reported a large (at least 2 point) improvement in pain interference with activity or mood. In a recently published study in the Journal of Pain and Relief, Quell users showed statistically and clinically significant decrease in pain outcome after 60 days of use. There were no differences in pain outcomes or dose-response associations between study participants with distal chronic pain (i.e., affecting the feet and legs) and proximal chronic pain (i.e., hips, lower back and upper body). This result suggests that Quell produces pain relief beyond the site of stimulation at the calf.

Results of an external pilot study conducted at the Brigham and Women's Hospital Pain Management Center were presented at the 9th World Congress of the Work Institute of Pain. Key findings of this randomized clinical trial include: subjects with chronic low back pain in the experimental (Quell) group demonstrated reduced pain intensity compared to control (treatment as usual) subjects; subjects in the experimental group exhibited reduced pain interference with function and pain catastrophizing compared to the control group.

In addition, results of internal studies based on data from Quell Health Cloud™ have been presented at various research conferences.

At the American Academy of Neurology Annual Meeting a leading researcherposter entitled “Pilot Study of Sleep/Wake Classification by Leg-Worn Actigraphy” reported an accuracy study of the sleep monitoring technology in the Quell device by comparing it to the accuracy of gold standard polysomnography. The study was conducted in collaboration with researchers at the Massachusetts General Hospital employing our wearable technology for restless leg syndrome, or RLS. The results indicatedHospital.

At the American Academy of Pain Medicine Annual Meeting, a meaningful reductionposter entitled “Levels and Predictors of Activity in RLS symptomsUsers of Wearable Neurostimulators with Chronic Pain” explored activity levels in Quell users and asassociated health. A second poster entitled “Does Fixed-Site High-Frequency Transcutaneous Electrical Nerve Stimulation Provide Analgesia Beyond Application Site?” addressed the widespread analgesic effect of Quell neurostimulation.

At the PAINWeek National Conference a result, we will consider a study in a larger RLS population. Also during the third quarterposter entitled “Effectiveness of 2015 we completed an external study managed by Ipsos-Vantis of our wearable technology for chronic painFixed-Site High-Frequency Transcutaneous Electrical Nerve Stimulation among subjectsIndividuals with several diseases accompanied by chronic pain.

Competition


We believe there is no direct competition to our neuro-stimulation devices, Quell and SENSUS,wearable neurostimulation device for the treatment of chronic pain. The most common approach to chronic pain is pain medication. This includes over-the-counter drugs (such as Advil and Motrin), and prescription drugs including anti-convulsants (such as Lyrica and Neurontin) and anti-depressants (such as Cymbalta and Elavil). Topical creams may also be used (such as Zostrix and Bengay). With severe pain, narcotic or opioid pain medications may be prescribed (such as codeine, fentanyl, morphine, and oxycodone). The approach to treatment is individualized, drug combinations may be employed, and the results are often hit or miss. Side effects and the potential for addiction are real and the risks are substantial.


TABLE OF CONTENTS

Reflecting the difficulty in treating chronic pain, inadequate relief leads many pain sufferers to turn to the over-the-counter market for supplements or alternatives to prescription pain medications. These include non-prescription medications, topical creams, lotions, electrical stimulators, dietary products, braces, sleeves, pads and other items. In total they account forthe United States, over $4 billion in annual spending in the United Statesis spent annually on such pain relief products.

High frequency nerve


Nerve stimulation is an established treatment for chronic pain supported by numerous clinical studies demonstrating efficacy. In simplified outline, the mechanism of action involves intensive nerve stimulation to activate the body’s central pain inhibition system resulting in widespread analgesia, or pain relief. The nerve stimulation activates brainstem pain centers leading to the release of endogenous opioids that act primarily through the delta opioid receptor to reduce pain signal transmission through the central nervous system. This therapeutic approach is available through deep brain stimulation and through implantable spinal cord stimulation; however, both requirethis approach requires surgery and havehas attendant risks. Non-invasive approaches to neuro-stimulationneurostimulation (transcutaneous electrical nerve stimulation, or TENS) have achieved limited efficacy in practice due to device limitations, ineffective dosing and low patient compliance.adherence. We believe that Quell and SENSUSour clinical and market claims with respect to our wearable technology covering chronic pain and sleep, technical characteristics of high power and automation, and the digital health integration characteristics (Quell), place our productsQuell in a unique neuro-stimulationneurostimulation category. There are numerous manufacturers of transcutaneous electrical nerve stimulation devices including widely marketed over-the-counter TENS such as Sanofi’s IcyHotSmartRelief,IcyHot SmartRelief, Omron PM3030 and Homedics RapidRelief.

Aleve Direct Therapy.


We believe that DPNCheck is currently the only objective and standardized test for DPN widely available at the point-of-care. The American Diabetes Association or ADA, and other organizations recommend at least annual evaluation of all people with diabetes for DPN. Due to cost and availability, this screen is typically performed with a simple (5.07/10g) monofilament. This subjective method identifies late stage neuropathy where intervention is generally limited to foot care. Experts in the field have indicated that there is an unmet need for a practical, objective, and sensitive test for diabetic neuropathy that can be widely deployed in the regular care of all people with diabetes. Monofilaments (5.07/10g) are a commodity sold by a number of medical supply companies.


There are several companies that sell neurodiagnostic devices that compete with our ADVANCE System. These companies include Cadwell Laboratories, Inc. and Natus Medical Incorporated. Natus Medical Incorporated has substantially greater financial resources than we do. Natus Medical Incorporated and Cadwell Laboratories, Inc. have established reputations as having effective worldwide distribution channels for medical instruments to neurologists and PM&Rphysical medicine and rehabilitation physicians.


Intellectual Property


We rely on a combination of patents, trademarks, copyrights, trade secrets, and other intellectual property laws, nondisclosure agreements and other measures to protect our proprietary technology, intellectual property rights, and know-how. We hold issued utility patents covering a number of important aspects of our Quell, SENSUS, and DPNCheck and ADVANCE products. We believe that in order to have a competitive advantage, we must develop and maintain the proprietary aspects of our technologies. We also require our employees, consultants and advisors, whom we expect to work on our products, to agree to disclose and assign to us all inventions conceived, or developed using our property, or which relate to our business. Despite any measures taken to protect our intellectual property, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary.




Patents


As of December 31, 2015,2018, we had 4342 issued U.S. patents, twofive issued foreign patent,patents, and 34 pending32 patent applications, including 1529 U.S. applications, and 18three foreign national applications.

With regard to our legacy neurodiagnostic products, our issued design patents began to expire in 2015, and our issued utility patents beginbegan to expire in 2017. In particular, seven of our issued U.S. utility patents covering various aspects of the legacy neurodiagnostic products will expireexpired on the same date in 2017. Although the patent protection for material aspects of these products covered by the claims of the patents will bewere lost at that time, we have additional patents and patent applications directed to other novel inventions that will have patent terms extending beyond 2017.

2018.


The medical device industry is characterized by the existence of a large number of patents and frequent litigation based on allegations of patent infringement. Patent litigation can involve complex factual and legal questions, and its outcome is uncertain. Any claim relating to infringement of patents that is successfully asserted against us may require us to pay substantial damages. Even if we were to prevail, any litigation could be costly and time-consuming and would divert the attention of our management and key personnel from our business operations. Our success will also depend in part on our not infringing patents issued to others, including our competitors and potential competitors. If our products are found to infringe the patents of others, our development, manufacture, and sale of these potential products could be severely restricted or prohibited. In addition, our competitors may independently develop similar technologies. Because of the importance of our patent portfolio to our business, we may lose market share to our competitors if we fail to protect our intellectual property rights.


A patent infringement suit brought against us may force us or any strategic partners or licensees to stop or delay developing, manufacturing, or selling potential products that are claimed to infringe a third-party’s intellectual property, unless that party grants us rights to use its intellectual property. In such cases, we may be required to obtain licenses to patents or proprietary rights of others in order to continue to commercialize our products. However, we may not be able to obtain any licenses required under any patents or proprietary rights of third parties on acceptable terms, or at all. Even if we were able to obtain rights to the third-party’s intellectual property, these rights may be non-exclusive, thereby giving our competitors access to the same intellectual property. Ultimately, we may be unable to commercialize some of our potential products or may have to cease some of our business operations as a result of patent infringement claims, which could severely harm our business.


Trademarks


We hold domestic registrations for the trademarks NEUROMETRIX, Quell, OptiTherapy, DPNCheck, SENSUS, and NC-stat. We use a trademark for ADVANCE, OptiTherapy, and Wearable Pain Relief Technology.Technology, and Quell Health Cloud. We hold certain foreign registrations for the marks NEUROMETRIX, Quell, OptiTherapy, NC-stat, and SENSUS.


Third-Party Reimbursement


Procedures performed with our neurodiagnostic medical devices including ADVANCE and DPNCheck may be paid for by third-party payers, including government health programs, such as Medicare, and private insurance and managed care organizations. The 20152019 Physicians Fee Schedule published by CMSthe Centers for Medicare & Medicaid Services (CMS) includes CPT 95905 for nerve conduction studies performed with pre-configured electrode arrays such as arethose used with the DPNCheck device and the ADVANCE System.


We believe that physicians are generally receiving reimbursement under CPT 95905 from Medicare for nerve conduction studies performed for carpal tunnel syndrome using pre-configured electrode arrays that meet the medical necessity requirements in their local Medicare region but that commercial insurers are generally not providing reimbursement. Reimbursement by third-party payers is an important element of success for medical device companies. We do not foresee a significant near-term improvement in reimbursement for procedures performed with ADVANCE and DPNCheck.


In the United States, some insured individuals are receiving their medical care through managed care programs which monitor and often require pre-approval of the services that a member will receive. Some managed care programs are paying their providers on a per capita basis a predetermined annual payment per member which puts the providers at financial risk for the services provided to their members. This is generally the case under Medicare Advantage where contracting insurers receive a monthly capitated fee from CMS to provide all necessary medical care to participating members. These capitated fees are adjusted under CMS’s risk-adjustment model which uses health status indicators, or risk scores, to ensure the adequacy of


payment. Members with higher risk codes generally require more healthcare resources than those with lower risk codes.


TABLE OF CONTENTS

In turn, the insurer fully absorbs the risk of patient health care costs. Insurers may share a portion of the risk with provider organizations such as independent practice associations (IPAs) with whom they contract to provide medical services to their members. Proper assessment of each member’s health status and accurate coding helps to assure that insurers receive capitation fees consistent with the cost of treating these members. Nerve conduction testing can provide valuable, early identification of neuropathy leading to clinical interventions that can reduce health care costs. Also, these tests provide valuable input regarding each member’s health risk status which can result in more appropriate capitated payments from CMS. We believe that the clinical and economic proposition for DPNCheck is attractive to Medicare Advantage insurers and risk bearing provider organizations. We are focusing our United States sales effort for DPNCheck on the Medicare Advantage managed care market segment.


We believe that theour legacy SENSUS pain management therapeutic system is considered a durable medical equipment (DME) benefit and is reimbursed for chronic pain by Medicare and many commercial insurers under HCPCSthe Healthcare Common Procedure Coding System (HCPCS) code EO730 for the device and under HCPCS code A4595 for the consumable electrodes. These pre-existing codes apply to DME benefits employing transcutaneous electrical nerve stimulation equipment. We expect that Quell will generally not be reimbursed by third party payers.

payers in the near future.


We believe that the overall escalating cost of medical products and services has led to, and will continue to lead to, increased pressures on the healthcare industry to reduce the costs of products and services.


Our success in selling DPNCheck SENSUS and ADVANCE will depend upon, among other things, our customers receiving, and our potential customers'customers’ expectation that they will receive sufficient reimbursement or patient capitated premium adjustments from third-party payers for procedures or therapies using these products. See “Risk Factors,”“If health care providers are unable to obtain sufficient reimbursement or other financial incentives from third-party health care payers related to the use of our products other than Quell, thetheir adoption of our products and our future product sales will be materially adversely affected.”


FDA and Other Governmental Regulation

FDA


U.S. Food and Drug Administration (FDA) Regulation


Our products are medical devices that are subject to extensive regulation by the U.S. FDA under the Federal Food, Drug, and Cosmetic Act, or FDCA, and the regulations promulgated thereunder, as well as by other regulatory bodies in the United States and abroad. The FDA classifies medical devices into one of three classes based on the basis of the amount of riskrisks associated with the medical device and the controls deemed necessary to reasonably ensure theirthe device’s safety and effectiveness:

effectiveness. Those three classes are:
Class I, requiringthe lowest risk products, which require compliance with medical device general controls, including labeling, establishment registration, device product listing, adverse event reporting and, for some products, adherence to good manufacturing practices through the FDA’s quality system regulations and pre-market notification;regulations;
Class II, requiringcomprising moderate-risk devices, which also require compliance with general controls and in some cases, so-called special controls whichthat may include performance standards, particular labeling requirements, or post-market surveillance obligations; typically a Class II device also requires pre-market review and post-market surveillance;clearance by FDA of a pre-market notification (also referred to as a “510(k) application”) as well as adherence to the quality system regulations/good manufacturing practices for devices; and
Class III, requiringhigh-risk devices that are often implantable or life-sustaining, which also require compliance with the medical device general controls and quality system regulations, but which generally must be approved by FDA before entering the market, through a more lengthy pre-market approval or PMA, which may(PMA) application. Approved PMAs can include post-approval conditions and post-market surveillance.surveillance requirements, analogous to some of the special controls that may be imposed on Class II devices.

Before being introduced into the U.S. market, our products must obtain marketmarketing clearance or approval from FDA through the 510(k) pre-market notification process, thede novo review classification process (summarized below under De Novo Classification Process), or the PMA process, unless they are determined to be Class I devices or to otherwise qualify for an exemption from one of these processes.available forms of pre-market review and authorization by the FDA. To date, our products have all been classified as Class II, moderate-risk medical devices and have been subject to the 510(k) review and clearance process. See “Risk Factors,”“We are subject to extensive regulation by the FDA which could restrict the sales and marketing of the Quell SENSUS and DPNCheck devices and the ADVANCE System, as well as other products for which we may seek FDA clearance or approval, and could cause us to incur significant costs.”




In recent months, FDA has announced a series of efforts to modernize and streamline the 510(k) notification and regulatory review process and for monitoring device post-market safety, as well as issued a Proposed Rule to formalize the De Novo classification process to provide clarity to innovative device developers.


510(k) Pre-Market Notification Process


Class II devices typically require pre-market review and clearance by the FDA, which is accomplished through the submission of a 510(k) pre-market notification before the device may be marketed. To obtain 510(k) clearance, we must submitdemonstrate that a pre-market notification demonstrating that the proposednew device is substantially equivalent to a legally marketed Class Ianother device with 510(k) clearance or II medical devicegrandfathered status, or to a device that was reclassified from Class III to Class II or Class I - this device marketed prior to May 28, 1976 for which the FDA has not requirednew device is compared is called the submission of a PMA application.“predicate device.” In some cases, we may be required to perform clinical trials to support a claim of substantial equivalence.


TABLE OF CONTENTS

If clinical trials are required, we mustmay be required to submit an application for an investigational device exemption, or IDE, which must be cleared by the FDA prior to the start of a clinical investigation, unless the device and clinical investigation are considered non-significant risk by the FDA or are exempt from the IDE requirements. Whether or not an IDE is required for a clinical study involving a medical device, an appropriate Institutional Review Board (IRB) must review and approve the study protocol before it is initiated. It generally takes three months from the date of the pre-market notification submission to obtain a final 510(k) clearance decision from the FDA, but it can be significantly longer.


After a medical device receives a 510(k) clearance letter, which authorizes commercial marketing of the new device for one or more specific indications for use, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires the submission of a new 510(k) clearancenotification or could requirede novo classification or a PMA. The FDA allows each company to make this determination, but the FDA can review the decision.decision as part of routine compliance audits of the company. If the FDA disagrees with a company’s decision not to seek prior FDA authorization, the FDA may require the company to seek additional 510(k) clearance or PMA.pre-market approval. The FDA also can require the company to cease marketing and/or recall the medical device in question until its regulatory status is resolved.


De Novo ReviewClassification Process


If the FDA determines that a new, previously unclassified new medical device does not qualify for the 510(k) pre-market notification process because thereor its intended use is no predicate device to which it is substantially equivalent, and if the device may be adequately regulated through general controls or special controls, the device may be eligible forde novo classification through what is called thede novo review process. In order to use the de novo review process, a company must receive a letter from the FDA stating that, because the device has been found not substantially equivalent to a legally marketed Class I or II medicalpredicate device, or to athe device is automatically placed into Class III, device marketed prior to May 28, 1976 for which the FDA has not requiredrequiring the submission of a PMA application, it has been placed into Class III. After receiving this letter,PMA. Devices that cannot be cleared through the company, within 30 days, must submit510(k) process due to lack of a predicate device but would be considered low or moderate risk (in other words, they do not rise to the FDAlevel of requiring the approval of a request for a risk based down classification ofPMA because any risks associated with the device from Class III to Class I could be mitigated through general controls and/or II based on the device’s moderate or low risk profile which meets the definition of a Class I or Class II medical device. The FDA then has 60 days in which to decide whether to down classify the device. If the FDA agrees that a lower classification is warranted, it will issue a new regulation describing the device type and, for a Class II device, publish a Special Controls guidance document. The Special Controls guidance document specifies the scope of the device type and the recommendations for submission of subsequent devicesspecial controls) may be eligible for the same intended use.510(k) De Novo classification process. If a product is classified as Class II through thede novo reviewDe Novo classification process, then that device may serve as a predicate device for subsequent 510(k) pre-market notifications.


On December 7, 2018, FDA issued a Proposed Rule that would formally codify requirements for the medical device De Novo process and the procedures and criteria for product developers to file a De Novo classification request. Over the past twenty years, the De Novo process has been implemented by FDA pursuant to statutory authorities and somewhat organically through informal guidance and iterative changes by Congress. The Proposed Rule now allows industry to participate in the development of FDA’s policies and procedures for De Novo requests through the notice-and-comment rulemaking process. Although this Proposed Rule, if finalized by FDA, would not impact our marketed products, FDA’s activities to create predictability, consistency, and transparency for innovative medical device developers may benefit the medical technology industry as a whole.

PMA Application Process


If a medical device does not qualify for the 510(k) pre-market notification process and is not eligible for clearanceclassification as a low or moderate-risk device through thede novo reviewDe Novo process, the device is deemed to be Class III and a company must submit a PMA application. Theapplication to seek authorization for its commercial sale. A PMA requires more extensive pre-filing testing than is required in the 510(k) application and is more costly, lengthy and uncertain. The FDA will decide within 45 days of receiving a PMA whether it is sufficiently complete to permit a substantive review and if the PMA is complete, the FDA will notify the applicant that the PMA has been filed. The PMAapproval process can take one to three years or longer, from the time the PMA application is filed with the FDA. TheUnder a PMA, process requires the company must demonstrate to provethe FDA that the new medical device is safe and effective for its intended purpose. A PMA typically includes extensive pre-clinical and clinical trial data, and information about the device, its design, manufacture, labeling and components. Before approving a PMA, the FDA generally also performs an on-site inspection of manufacturing facilities for the product to ensure compliance with the FDA’s quality system regulation, or QSR.




If FDA approves the PMA, the approved indications may be more limited than those originally sought. In addition, FDA’s approval order may include post-approval conditions that the FDA believes necessary to ensure the safety and effectiveness of the device, including, among other things, restrictions on labeling, promotion, sale and distribution and post-market study requirements. Failure to comply with the post-approval conditions can result in adverse enforcement or administrative actions, including the withdrawal of the approval. Approval of a new PMA application or a PMA supplement may be required in the eventbefore making certain types of modifications to the device, including to its labeling, intended use or indication, or its manufacturing process, thatespecially when such modifications have the potential to affect safety and effectiveness.


Post-Marketing Compliance Obligations

TABLE OF CONTENTS

Post-Approval Obligations

After

Regardless of which pre-market pathway a medical device uses to reach the U.S. market, after a device is placed on the market, numerous regulatory requirements continue to apply. These include:


the FDA’s QSR, which requires manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and other good manufacturing practice and quality assurance procedures during all aspects of the manufacturing process;process (unless a device category is exempt from this requirement by the FDA, such as in the case of many Class I devices);
labeling regulations and FDA prohibitions against the promotion of products for uncleared or unapproved uses (known as off-label uses), as well as requirements to provide adequate information on both risks and benefits;
medical device reporting regulations, which require that manufacturers report to FDA any event that the company learns of in which a device that may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction were to recur;
correction and removal reporting regulations, which require that manufacturers report to the FDA field corrections and device recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA caused by the device whichthat may present a risk to health;
post-market surveillance regulations, which apply to Class II or III devices if the FDA has issued a post-market surveillance order and the failure of the device would be reasonably likely to have serious adverse health consequences, the device is expected to have significant use in the pediatric population, the device is intended to be implanted in the human body for more than one year, or the device is intended to be used to support or sustain life and to be used outside a user facility;
regular and for causefor-cause inspections by FDA to review a manufacturer’s facilitiesfacility and theirits compliance with applicable FDA requirements; and
the FDA’s recall authority, whereby it can ask, or order, device manufacturers to recall from the market a product that is in violation of applicable laws and regulations.

Regulatory Approvals and Clearances


The ADVANCE System received 510(k) clearance as a Class II medical device in April 2008 for its intended use by physicians to perform nerve conduction studies and needle electromyography procedures.


The NC-stat System is also a Class II medical device and has been the subject of several 510(k) clearances, the most recent in July 2006 (K060584). The NC-stat System is cleared for use to stimulate and measure neuromuscular signals that are useful in diagnosing and evaluating systemic and entrapment neuropathies. We believe our NC-stat DPNCheck, or DPNCheck, device is a technical modification to the 510(k) cleared NC-stat device and has the same intended use, and therefore does not raise safety or effectiveness questions. Under the FDA’s published guidance on 510(k) requirements for modified devices, we do not believe that a 510(k) submission is required for DPNCheck.


As transcutaneous electrical nerve stimulators, the SENSUS and Quell pain therapy devices are Class II medical devices whichthat received 510(k) clearance from the FDA in August 2012 and July 2014, respectively. In November 2012, the FDA provided 510(k) clearance for the disposable electrode used in conjunction with the SENSUS device, and in July 2013, the FDA provided 510(k) clearance for the use of SENSUS during sleep. The intended use of the SENSUS pain management therapeutic system is the symptomatic relief and management of chronic pain. While the SENSUS device is still marketed we have transitioned many SENSUS customers to the newer models of our transcutaneous electrical nerve stimulator, called Quell. In July 2014, our Quell device received 510(k) clearance for over-the-counter use and in November 2014, our Quell disposable electrode received 510(k) clearance for over-the-counter use. In January 2016, a number of new features were added to Quell and received 510(k) clearance, most notably use with an optional mobile app that contains several convenience features. The intended use of the Quell pain management therapeutic system is the symptomatic relief and management of chronic pain. The Quell device may also be used during nighttime sleep.

Federal Trade Commission Regulatory Oversight

We are subject to Federal Trade Commission (FTC) regulatory oversight. Under the Federal Trade Commission Act (FTC Act), the FTC is empowered, among other things, to (a) prevent unfair methods of competition and unfair or deceptive acts or practices in or affecting commerce; (b) seek monetary redress and other relief for conduct injurious to consumers; and (c) gather and compile information and conduct investigations relating to the organization, business, practices, and management of entities engaged in commerce. The FTC has very broad enforcement authority, and failure to abide by the substantive requirements of the FTC Act and other consumer protection laws can result in administrative or judicial penalties, including civil penalties, injunctions affecting the manner in which we would be able to market Quell in the future, or criminal prosecution. In 2017, the Company received a Civil Investigative Demand (CID) from the FTC. The CID requested information in connection with an FTC review for compliance of the Company’s representations about Quell with Sections 5 and 12 of the FTC Act. The Company produced and supplied to the FTC all documents and information in response to the CID. To the knowledge of the Company, no complaint has been filed against the Company; however, no assurance can be given as to the timing or outcome of the investigation. FTC counsel has communicated that they continue to review our information and documents, but they have not provided a timeframe for completion of that review or for potential closure of the investigation.

Manufacturing Facilities


Our facility, and the facilityfacilities utilized by Sunburst and MC Assembly., our contract device and sub-assembly manufacturer,manufacturers, have each been inspected by FDA in the past, and observations were noted. There were no findings that involved a significant violation of regulatory requirements. The responses to these observations have been


TABLE OF CONTENTS

accepted by the FDA and we believe that we and our contract manufacturermanufacturers are in substantial compliance with the QSR. We expect that our facility and our subcontract facilities will be inspected again as required by the FDA. If the FDA finds significant violations, we could be subject to fines, recalls, requirements to halt manufacturing, or other administrative or judicial sanctions.

U.S. Anti-Kickback and False Claims Laws

In the United States, the federal Anti-Kickback Statute, as well as numerous state anti-kickback laws, prohibit the offer, payment, solicitation or receipt of kickbacks, bribes or other remuneration, whether direct or indirect, overt or covert, in cash or in kind, intended, among other things, to induce the purchase or recommendation of healthcare products and services. While the federal law applies only to products and services for which payment may be made by a federal healthcare program, the state laws may apply regardless of whether any public healthcare funds are involved. Violations of these laws can lead to severe civil and criminal penalties, including exclusion from participation in federal healthcare programs. These laws are potentially applicable to manufacturers of medical devices, such as us, and to hospitals, physicians and other potential purchasers of our products.

Also, the federal False Claims Act, as well as many state false claims statutes, provides civil and criminal penalties for presenting, or causing to be presented, to third-party payers for reimbursement, claims that are false or fraudulent, or which are for items or services that were not provided as claimed. Under the federal False Claims Act, in addition to actions initiated by federal law enforcement authorities, the statute authorizes “qui tam” actions to be brought on behalf of the federal government by a private party in certain circumstances and, if successful, that private party can share in any monetary recovery. Any challenge by federal or state enforcement officials or others under these laws, could have a material adverse effect on our business, financial condition, and results of operations.


Legacy Neurodiagnostics Business

Products


We were founded in 1996 as a science-based health care company. Our focus had beencompany focused on the development of innovative products for the detection, diagnosis, and monitoring of peripheral nerve and spinal cord disorders, such as those associated with carpal tunnel syndrome, lumbosacral disc disease and spinal stenosis, and diabetes. Our NC-stat System for the performance of nerve conduction studies at the point-of-care was commercially launched in 1999. The1999 and the second generation NC-stat was released in 2002. In 2008, we brought to market the more sophisticated ADVANCE System for nerve conduction testing and performance of invasive needle electromyography. These systems were general purpose with broad application in evaluating and diagnosing nerve disorders. Numerous studies demonstrating the clinical accuracy and utility of these devices have been conducted and published in high quality peer-reviewed journals. Furthermore, these devices have been used in FDA sanctioned clinical trials for pharmacological agents and large scalelarge-scale epidemiological studies sponsored by the NIH, Center for Disease Control or CDC, and other governmental agencies. The products have been cleared by the FDA, field tested for over a decade and highly regarded for their ease of use, accuracy and reproducibility of results.

Following launch of NC-stat in 1999, we experienced rapid revenue growth, which led to our initial public offering in 2004. The health market, particularly the physician office segment, embraced the opportunity to perform nerve conduction tests which previously had always required referral to specialists. Point-of-care nerve testing was seen to provide a combination of improved patient care and patient convenience. The success of point-of-careHowever, significant changes to health reimbursement during 2006-2009 adversely affected the financial profile on our NC-stat and ADVANCE nerve conduction testing products, particularly when used by non-specialists. This resulted in declining Company revenues and ultimately our decision to discontinue investment in the products and to manage them for cash flow and not for growth. They are now classified as Legacy Products. Also, our initial prescription wearable technology for chronic pain called SENSUS has been classified as a market which we created, was met with resistance in some sectorsLegacy Product since our 2015 launch of the medical community, particularly by neurologists and physical medicine and rehabilitation physicians, both of which had traditionally provided nerve testing services. As a consequence of successful lobbying by these specialists, physicians using our technology experienced increased denials of coverage by third party payers resulting in their discontinuing usage and our difficulty in accruing new customer accounts. In late 2009 CMS included in the Physician Fee Schedule a new Category I CPT Code, CPT 95905, for nerve conduction studies performed using preconfigured electrode such as those employed with our products. During 2010 most Medicare fiscal intermediaries assumed coverage for CPT 95905 for at least some clinical indications; however, the health care environment has been such that we have been unable to secure broad coverage among private payers, which is essential to the success of our ADVANCE System product. This experience was reflected in our revenues for the legacy Neurodiagnostics business, which peaked in 2006 at

TABLE OF CONTENTS

ITEM 1A. Risk Factors


You should carefully consider the following risks and all other information contained in this Annual Report on Form 10-K and our other public filings before making any investment decisions with respect to our securities. If any of the following risks occurs, our business, prospects, reputation, results of operations, or financial condition could be harmed. In that case, the trading price of our securities could decline, and our stockholders could lose all or part of their investment. This Annual Report also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of specific factors, including the risks described below and elsewhere in this Annual Report on Form 10-K.


We have incurred significant operating losses since inception and cannot assure you that we will achieve profitability.


We have incurred significant cumulative netrecurring losses since our inception. Our net losses for the years ended December 31, 2015, 2014,from operations and 2013, were approximately $9.2 million, $7.8 million, and $8.0 million, respectively.negative cash flows from operating activities. At December 31, 2015,2018, we had an accumulated deficit of $163.6$191.0 million. The extent of our future operating income or losses is highly uncertain, and we cannot assure you that we will be able to achieve or maintain profitability.


Our future capital needs are uncertain and our independent auditor has expressed substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern is dependent on our ability to achieve GSK collaboration milestones or to raise additional capital and our operations could be curtailed if we are unable to obtain the required additional funding when needed. We may not be able to do so when necessary, and/or the terms of any financings may not be advantageous to us.


We held cash and cash equivalents of $12.5$6.8 million as of December 31, 2015.2018. We believe that these resources, future GSK collaboration milestones and payments, and the cash to be generated from future product sales will be sufficient to meet our projected operating requirements through 2019. However, the second quartertiming of 2016. However,GSK milestone achievement and the amount of our future product sales is difficult to predict especially in light of the limited nature of the recent commercialization of Quell, and actual sales may not be in line with our forecasts.

Accordingly, we may need to raise additional funds to support our future operating and capital needs in 2020.


Our financial statements have been prepared assuming that we will continue as a going concern which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. We expect to incur further losses as we aim to successfully commercialize Quell and DPNCheck and the operations of our business andwe will be dependent on funding our operations through the achievement of milestones under the GSK collaboration, additional public or private financing, collaborative arrangements with strategic partners, or through additional credit lines or other debt financing sources to increase the funds available to fund operations.sources. These circumstances raise substantial doubt about our ability to continue as a going concern.concern for the one-year period from the date of issuance of these financial statements. As a result of this uncertainty and the substantial doubt about our ability to continue as a going concern as of December 31, 2015,2018, the report of our independent registered public accounting firm in this Annual Report on Form 10-K for the yearyears ended December 31, 20152018 and 2017 includes a going concern explanatory paragraph. Management’s plans include increasing revenue through the commercialization of Quell and DPNCheck. However, no assurance can be given at this time as to whether we will be able to achieve these objectives. Our financial statements do not include any adjustment relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should we be unable to continue as a going concern.


We continue to face significant challenges and uncertainties and, as a result, our available capital resources may be consumed more rapidly than currently expected due to (a) decreases in sales of our products and the uncertainty of future revenues from new products; (b) changes we may make to the business that affect ongoing operating expenses; (c) changes we may make in our business strategy; (d) regulatory developments and inquiries affecting our existing products and delays in the FDA approval process for products under development;products; (e) changes in our research and development spending plans; (f) delays in the anticipated timing of GSK milestones; and (f)(g) other items affecting our forecasted level of expenditures and use of cash resources. Accordingly, we will need to raise additional funds to support our future operating and capital needs for the third quarter of 2016 and beyond. We may attempt to obtain additional funding through the achievement of milestones under the GSK collaboration, public or private financing, collaborative arrangements with strategic partners, or through additional credit lines or other debt financing sources to increase the funds available to fund operations. However, we may not be able to secure such financing in a timely manner or on favorable


TABLE OF CONTENTS

terms, if at all. Furthermore, if we issue equity or debt securities to raise additional funds, our existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of our existing stockholders. If we raise additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to our potential products or proprietary technologies, or grant licenses on terms that are not favorable to us. Without additional funds, we may be forced to delay, scale back or eliminate some of our sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient



funds to continue our operations. If any of these events occurs, our ability to achieve our development and commercialization goals would be adversely affected.


We are focused on the commercialization within the United States of Quell, our over-the-counter, or OTC, wearable device for chronic pain. We cannot assure you that we will be successful in this field or that our current commercial product for peripheral neuropathy, DPNCheck, or the product candidates or product enhancements in our development pipeline, will be successful.


We are focused on the commercialization within the United States of Quell, our OTC wearable device for pain relief. Quell is based on our prescription product for pain relief, SENSUS. Quell has been on the market since June 2015 and we have shipped approximately 13,800over 180,000 Quell devices since then. Additionally,We are also focused on the growth of DPNCheck, which was launched in 2011, and is a quantitative nerve conduction test for systemic neuropathies such as DPN. We also have other product candidates and product enhancements in our development pipeline. Our future prospects are closely tied to our success with Quell and DPNCheck, which, in turn, depend upon market acceptance and growth in future revenues.revenues and margins. We cannot assure you that our commercialization strategy will be successful. If our strategy is not successful, it could materially affect our revenues and results of operations.


Our future success could be adversely affected by a number of factors, including:

inability to efficiently create market demand for Quell at profitable pricing levels through a direct sales force, through onlineour TV and digital marketing efforts, direct response television and other retail channels;efforts;
manufacturing issues with Quell or our other products;
inability to increase adoption of DPNCheck within the Medicare Advantage market;market and Outside the United States (OUS) markets;
unfavorable market response to DPNCheck in Japan and other Asia markets;regulatory inquiries or issues affecting our products;
unfavorable changes to current Medicare, Medicare Advantage and commercial payer payment policies;
changes to payor policies under the Patient Protection and Affordable Care Act;
unfavorable experiences by patients and physicians using Quell and our other products; and,
physicians’ or patients' reluctance to alter their existing practices and adopt the use of our devices.

If we are unable to expand exposure and penetrate the market demand for Quell and/orand DPNCheck, our ability to increase our revenues will be limited and our business prospects will be adversely affected.


Our current and future revenue is dependent upon commercial acceptance of Quell by the market. The failure of such acceptance will materially and adversely affect our operations.


We anticipate that as revenue from our legacy neurodiagnostics business, the ADVANCE System, continues to decrease, we will rely more heavily on revenue from sales of Quell, our OTC wearable device. As a result, we will continue to incur operating losses until such time as sales of Quell, DPNCheck and other products or product candidates reach a mature level and we are able to generate sufficient revenue from their sale to meet our operating expenses. There can be no assurance that customers will adopt our technology and products, or that prospective customers will agree to pay for our products. In the event that we are not able to significantly increase the number of customers that purchase our products, or if we are unable to charge the necessary prices, our financial condition and results of operations will be materially and adversely affected.


An inability to work together with GSK or delays in their commercialization timelines could materially and adversely affect our operations.

TABLE OF CONTENTS


We are in the second year of our GSK collaboration following the Asset Purchase Agreement, the Development and Services Agreement and related documents, which were signed in January 2018. Under those agreements we sold to GSK the rights to market Quell outside the United States in exchange for $26.5 million in milestone payments. In addition, we agreed to jointly fund the development of Quell during 2019 and 2020. In December 2018 we executed Amendment #1 to the Development and Services Agreement which restructured the milestones and had the effect of accelerating milestone timing and recognizing and a time-value-of money adjustment. While we believe that we have a strong and mutually beneficial working relationship with GSK, we cannot predict whether that will continue in the future, whether we will be able to satisfy the milestone requirements, or whether GSK’s commercialization plans will change resulting in an adverse effect on our ability to satisfy the milestone requirements. Our inability to achieve milestones or delays in timing outside our control would have a material and adverse effect on our operations.
.



If health care providers are unable to obtain sufficient reimbursement or other financial incentives from third-party health care payers related to the use of our products other than Quell, their adoption and our future product sales will be materially adversely affected.


Widespread adoption of our SENSUS and DPNCheck products by the medical community is unlikely to occur without a financial incentive from third-party payers for the use of these products. If health care providers are unable to obtain adequate reimbursement for procedures performed using these products, and if managed care organizations do not receive improved capitated payments due to more accurate patient risk assessment using our products, and if DME suppliers are not adequately reimbursed for supplying our therapeutic products, we may be unable to sell our products at levels that are sufficient to allow us to achieve and maintain profitability, and our business would suffer significantly. Additionally, even if these products and procedures are adequately reimbursed by third-party payers today, adverse changes in payers future policies toward payment would harm our ability to market and sell our products. Third-party payers include those governmental programs such as Medicare and Medicaid, private health insurers, workers’ compensation programs and other organizations.


Future regulatory action by CMS or other governmental agencies or negative clinical results may diminish reimbursement payments to physicians for performing procedures using our products. Medicaid reimbursement differs from state to state, and some state Medicaid programs may not cover the procedures performed with our products or pay physicians an adequate amount for performing those procedures, if at all. Additionally, some private payers do not follow the Medicare guidelines and may reimburse for only a portion of these procedures or not at all. We are unable to predict what changes will be made in the reimbursement methods used by private or governmental third-party payers. Importantly, we cannot predict the effects that implementation of the Patient Protection and Affordable Care Act will have on CMS, commercial insurers, health care providers, and ultimately on our business.

Healthcare reform legislation could adversely affect our future revenues.

Our future revenues from SENSUS will be impacted by the CMS Durable Medical Equipment, Prosthetics, Orthotics and Supplies (DMEPOS) Competitive Bidding Program. Under this program, Medicare will no longer reimburse suppliers for certain products and services, including transcutaneous electrical nerve stimulation (TENS), based on the Medicare fee schedule amount. Instead CMS will provide reimbursement for those products and services based on a competitive bidding process. Our SENSUS pain management system is presently classified within TENS. The DMEPOS Competitive Bidding Program will likely require us to sell SENSUS devices and related consumables subject to Medicare reimbursement at significantly lower prices which would have a material adverse effect on SENSUS profitability. In those regions of the country where DMEPOS Competitive Bidding was implemented in January 2014, low Medicare pricing is restricting our ability to sell SENSUS. As the DMEPOS program is expanded to other regions, a similar effect will likely be seen.


We are subject to extensive regulation by the FDA which could restrict the sales and marketing of the Quell SENSUS and DPNCheck devices and the ADVANCE System, as well as other products for which we may seek FDA clearance or approval, and could cause us to incur significant costs.


We sell medical devices that are subject to extensive regulation in the United States by the FDA with regard to manufacturing, labeling, sale, promotion, distribution, shipping and ongoing monitoring and follow-up. Before a new medical device, or a new use of or claim for an existing product, can be marketed in the United States, it must first be cleared or approved by the FDA. Medical devices may be marketed only for the indications for which they are approved or cleared. The regulatory review process can be expensive and lengthy. The FDA’s process for granting 510(k) clearance typically takes approximately three to six months, but it can be significantly longer. The process for obtaining a pre-market approval, or PMA, is much more costly and onerous. By law, the time period designated for the FDA’s review of a PMA is 180 days; however, this time is often extended and it is not uncommon for the PMA review process to take three years or longer from the time the application is filed with the FDA.


The FDA may remove our devices from the market or enjoin them from commercial distribution if safety or effectiveness problems develop. Further, we may not be able to obtain additional 510(k) clearances or


TABLE OF CONTENTS

pre-market approvals for new products or for modifications to, or additional indications for, our existing products in a timely fashion, or at all. Delays in obtaining future clearances or approvals would adversely affect our ability to introduce new or enhanced products in a timely manner, which in turn would harm our revenue and future profitability. We have made modifications to our devices in the past and may make additional modifications in the future that we believe do not or will not require additional clearances or approvals. If the FDA disagrees, and requires new clearances or approvals for the modifications, we may be required to recall and to stop marketing the modified devices. If any of these events occurs or if the FDA takes other enforcement actions, we may not be able to provide our customers with the products they require on a timely basis, our reputation could be harmed, and we could lose customers and suffer reduced revenues and increased costs.


We also are subject to numerous post-marketing regulatory requirements, including the FDA’s quality system regulations, which relate to the design, manufacture, packaging, labeling, storage, installation and servicing of our products, labeling regulations, medical device reporting regulations and correction and removal reporting regulations. Our failure or the failure by any manufacturer of our products to comply with applicable regulatory requirements could result in enforcement action by the FDA. FDA enforcement actions relating to post-marketing regulatory requirements or other issues including any issues arising from the not substantially equivalent letter described above, may include any of the following:

warning letters, untitled letters, fines, injunctions, product seizures, consent decrees and civil penalties;


requiring repair, replacement, refunds, customer notifications or recall of our products;
imposing operating restrictions, suspension or shutdown of production;
refusing our requests for 510(k) clearance or PMA approval of new products, new intended uses, or modifications to existing products;
requesting voluntary rescission of 510(k) clearances or withdrawing PMA approvals that have already been granted; and
criminal prosecution.

If any of these events were to occur, they could harm our reputation, our ability to generate revenues and our profitability.


Also, from time to time, legislation is introduced into Congress that could significantly change the statutory provisions governing the approval, manufacturing and marketing of medical devices. FDA regulations and guidance are often revised or reinterpreted by the agency in ways that may significantly affect our business and our products. It is impossible to predict whether legislative changes will be enacted, or FDA regulations, guidance or interpretations changed, and what the impact of such changes, if any, may be. The FDA has publicly stated that it is reevaluating its longstanding 510(k) review program. It is not clear when, or if, the program will be modified and what effect the modified review process will have on our ability to bring our product candidates to market.


We depend on several single source manufacturers to produce components of our products. Any material adverse changes in our relationships with these manufacturers could prevent us from delivering products to our customers in a timely manner and may adversely impact our future revenues or costs.


We rely on third-party manufacturers to manufacture components of our Quell DPNCheck and SENSUS systems,DPNCheck, and to fully manufacture electrodesdevices for the ADVANCE system. In the event that our manufacturers cease to manufacture sufficient quantities of our products or components in a timely manner and on terms acceptable to us, we would be forced to locate alternate manufacturers. Additionally, if our manufacturers experience a failure in their production process, are unable to obtain sufficient quantities of the components necessary to manufacture our products, experience extraordinary price increases on parts essential to our products or otherwise fail to meet our quality requirements, we may be forced to delay the manufacture and sale of our products or locate an alternative manufacturer. We may be unable to locate suitable alternative manufacturers for our products or components for which the manufacturing process is relatively specialized, on terms acceptable to us, or at all. We have a manufacturing and supply agreement


TABLE OF CONTENTS

with Parlex Polymer Flexible Circuits, Inc.Johnson Medtech, LLC. for the manufacture of the ADVANCE electrodes for nerve conduction testing. Katecho, Inc. manufactures biosensors for use with our DPNCheck devices and manufactures electrodes for Quell, and SENSUS, and Sunburst EMS, Inc. manufactures electronic boards and other components of our Quell DPNCheck and SENSUSDPNCheck products which we assemble at our Massachusetts facility to produce completed devices. Moreover, due to the recent commercialization of Quell and the limited amount of our sales to date other than Katecho, Inc., we do not have long-standing relationships with our manufacturers, other than Katecho, Inc., and may not be able to convince suppliers to continue to make components available to us unless there is demand for such components from their other customers. As a result, there is a risk that certain components could be discontinued and no longer available to us.


We have experienced transient inventory shortages on newour products and essential parts, including Quell, during the initial production ramp-up phase.Quell. If any materially adverse changes in our relationships with these manufacturers or parts suppliers occur, our ability to supply our customers will be severely limited until we are able to engage an alternate manufacturer or parts supplier or, if applicable, resolve any quality issues with our existing manufacturer. This situation could prevent us from delivering products to our customers in a timely manner, lead to decreased sales or increased costs, or harm our reputation with our customers.


If our manufacturers are unable to supply us with an adequate supply of product components, as we expand our markets, we could lose customers, our potential future growth could be limited and our business could be harmed.


In order for us to successfully expand our business, within the United States and internationally, our contract manufacturers must be able to provide us with substantial quantities of components of our products in compliance with regulatory requirements, in accordance with agreed upon specifications, at acceptable cost and on a timely basis. Our potential future growth could strain the ability of our manufacturers to deliver products and obtain materials and components in sufficient quantities. Manufacturers often experience difficulties in scaling up production, including problems with production yields and quality control and assurance. If we are unable to obtain sufficient quantities of high quality products to meet customer demand on a timely basis, we could lose customers, our growth may be limited and our business could be harmed.




If we or our manufacturers fail to comply with the FDA’s quality system regulation, the manufacturing and distribution of our products could be interrupted, and our product sales and operating results could suffer.


We and our contract manufacturers are required to comply with the FDA’s quality system regulation, or QSR, which is a complex regulation that governs the procedures and documentation of the design, testing, production, control, quality assurance, labeling, packaging, sterilization, storage and shipping of our devices. The FDA enforces the QSR through periodic inspections. We cannot assure you that our facilities or the facilities of the manufacturers of our products would pass any future inspection. If our facilities or any of the facilities of the manufacturers of our products fail an inspection, the manufacturing or distribution of our products could be interrupted and our operations disrupted. Failure to take adequate and timely corrective action in response to an adverse inspection could result in a suspension or shutdown of our packaging and labeling operations and the operations of the manufacturers of our products or a recall of our products, or other administrative or judicial sanctions. If any of these events occurs, we may not be able to provide our customers with the quantity of products they require on a timely basis, our reputation could be harmed, and we could lose customers and suffer reduced revenues and increased costs.


We are subject to Federal Trade Commission regulatory oversight. Exercise of this regulatory oversight could lead to an outcome which would constrain our marketing of Quell, cause us to incur significant costs and penalties, and adversely affect our financial results.

Under the Federal Trade Commission Act (“FTC Act”), the FTC is empowered, among other things, to (a) prevent unfair methods of competition and unfair or deceptive acts or practices in or affecting commerce; (b) seek monetary redress and other relief for conduct injurious to consumers; and (c) gather and compile information and conduct investigations relating to the organization, business, practices, and management of entities engaged in commerce. The FTC has very broad enforcement authority, and failure to abide by the substantive requirements of the FTC Act and other consumer protection laws can result in administrative or judicial penalties, including civil penalties, injunctions affecting the manner in which we would be able to market Quell in the future, or criminal prosecution.

In 2017 we received a Civil Investigative Demand (“CID”) from the FTC. The CID requested information in connection with an FTC review for compliance of our representations about Quell with Sections 5 and 12 of the FTC Act. We believe we have provided all requested documents to the FTC. To our knowledge, no complaint has been filed against us; however, no assurance can be given as to the timing or outcome of the investigation.

Our products may be subject to recalls, even after receiving FDA clearance or approval, which would harm our reputation, business and financial results.


We are subject to the medical device reporting regulations, which require us to report to the FDA if our products may have caused or contributed to a death or serious injury, or have malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction were to occur. We are also subject to the correction and removal reporting regulations, which require us to report to the FDA any field corrections and device recalls or removals that we undertake to reduce a risk to health posed by the device or to remedy a violation of the Federal Food, Drug and Cosmetic Act, or FDCA, caused by the device which may present a risk to health. In addition, the FDA and similar governmental agencies in other countries have


TABLE OF CONTENTS

the authority to require the recall of our products if there is a reasonable probability that the products would cause serious adverse health consequences or death. A government-mandated or voluntary recall by us could occur as a result of manufacturing defects, labeling deficiencies, packaging defects or other failures to comply with applicable regulations. Any recall would divert management attention and financial resources and harm our reputation with customers and could have a material adverse effect on our financial condition and results of operations.


The success of our business depends upon our ability to advance our pipeline products to commercialization.


We commenced commercialization of Quell in June 2015. We have additional product candidates and enhancements of our existing products in our R&D pipeline. We expect that advancing our pipeline products will require significant time and resources. We may not be successful in our commercialization efforts for any of the product candidates or product enhancements currently in our pipeline and we may not be successful in developing, acquiring, or in-licensing additional product candidates, to the extent we decide to do so. If we are not successful advancing new products through our development pipeline, the regulatory process and commercial launch, our business, financial condition, and results of operations will be adversely affected.




Our ability to achieve profitability depends in part on maintaining or increasing our gross margins on product sales which we may not be able to achieve.


A number of factors may adversely impact our gross margins on product sales and services, including:

lower than expected manufacturing yields of high cost components leading to increased manufacturing costs;
shortages of electric components resulting in higher prices or an inability to supply key parts;
low production volume which will result in high levels of overhead cost per unit of production;
the timing of revenue recognition and revenue deferrals;
increased material or labor costs;
increased service or warranty costs or the failure to reduce service or warranty costs;
increased price competition;
variation in the margins across products in a particular period; and
how well we execute on our strategic and operating plans.

If we are unable to maintain or increase our gross margins on product sales, our results of operations could be adversely impacted, we may not achieve profitability and our stock price could decline.


The patent rights we rely upon to protect the intellectual property underlying our products may not be adequate, which could enable third parties to use our technology and would harm our ability to compete in the market.


Our success will depend in part on our ability to develop or acquire commercially valuable patent rights and to protect these rights adequately. The risks and uncertainties that we face with respect to our patents and other related rights include the following:

the pending patent applications we have filed or to which we have exclusive rights may not result in issued patents or may take longer than we expect to result in issued patents;
the claims of any patents that are issued may not provide meaningful protection;
we may not be able to develop additional proprietary technologies that are patentable;
other parties may challenge patents, patent claims or patent applications licensed or issued to us; and
other companies may design around technologies we have patented, licensed or developed.

Our issued and filed patents for our wearable therapeutic products are recent. With regard to our legacy neurodiagnostic products, our issued design patents beginbegan to expire in 2015, and our issued utility patents


TABLE OF CONTENTS

begin began to expire in 2017. In particular, seven of our issued U.S. utility patents covering various aspects of the legacy neurodiagnostic business expired on the same day in 2017. Although the patent protection for material aspects of these products covered by the claims of the patents will bewere lost at that time, we have additional patents and patent applications directed to other novel inventions that will have patent terms extending beyond 2017.2018. We may not be able to protect our patent rights effectively in some foreign countries. For a variety of reasons, we may decide not to file for patent protection in the United States or in particular foreign countries. In addition, GSK has certain rights to control the filing of patents with respect to Quell in certain foreign countries. Our patent rights underlying our products may not be adequate, and our competitors or customers may design around our proprietary technologies or independently develop similar or alternative technologies or products that are equal or superior to our technology and products without infringing on any of our patent rights. In addition, the patents licensed or issued to us may not provide a competitive advantage. If any of these events were to occur, our ability to compete in the market would be harmed.




Other rights and measures we have taken to protect our intellectual property may not be adequate, which would harm our ability to compete in the market.


In addition to patents, we rely on a combination of trade secrets, copyright and trademark laws, confidentiality, nondisclosure and assignment of invention agreements and other contractual provisions and technical measures to protect our intellectual property rights. We rely on trade secrets to protect the technology and algorithms we use in our customer data processing and warehousing information system. While we currently require employees, consultants and other third parties to enter into confidentiality, non-disclosure or assignment of invention agreements or a combination thereof where appropriate, any of the following could still occur:

the agreements may be breached or not enforced in a particular jurisdiction;
we may have inadequate remedies for any breach;
trade secrets and other proprietary information could be disclosed to our competitors; or
others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or disclose such technologies.

If, for any of the above reasons, our intellectual property is disclosed or misappropriated, it would harm our ability to protect our rights and our competitive position.


We may need to initiate lawsuits to protect or enforce our patents and other intellectual property rights, which could be expensive and, if we lose, could cause us to lose some of our intellectual property rights, which would harm our ability to compete in the market.


We rely on patents to protect a portion of our intellectual property and our competitive position. Patent law relating to the scope of claims in the technology fields in which we operate is still evolving and, consequently, patent positions in the medical device industry are generally uncertain. In order to protect or enforce our patent rights, we may initiate patent litigation against third parties, such as infringement suits or interference proceedings. Litigation may be necessary to:

assert claims of infringement;
enforce our patents;
protect our trade secrets or know-how; or
determine the enforceability, scope and validity of the proprietary rights of others.

Any lawsuits that we initiate could be expensive, take significant time and divert management’s attention from other business concerns. Litigation also puts our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing. Additionally, we may provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially valuable. The occurrence of any of these events could harm our business, our ability to compete in the market or our reputation.


TABLE OF CONTENTS

Claims that our products infringe on the proprietary rights of others could adversely affect our ability to sell our products and increase our costs.


Substantial litigation over intellectual property rights exists in the medical device industry. We expect that our products could be increasingly subject to third-party infringement claims as the number of competitors grows and the functionality of products and technology in different industry segments overlap. Third parties may currently have, or may eventually be issued, patents on which our products or technologies may infringe. Any of these third parties might make a claim of infringement against us. Any litigation regardless of its impact would likely result in the expenditure of significant financial resources and the diversion of management’s time and resources. In addition, litigation in which we are accused of infringement may cause negative publicity, adversely impact prospective customers, cause product shipment delays or require us to develop non-infringing technology, make substantial payments to third parties, or enter into royalty or license agreements, which may not be available on acceptable terms, or at all. If a successful claim of infringement were made against us and we could not develop non-infringing technology or license the infringed or similar technology on a timely and cost-effective basis, our revenues may decrease substantially and we could be exposed to significant liability.




We are subject to federal and state laws prohibiting “kickbacks” and false or fraudulent claims, which, if violated, could subject us to substantial penalties. Additionally, any challenge to or investigation into our practices under these laws could cause adverse publicity and be costly to respond to, and thus could harm our business.


A federal law commonly known as the federal anti-kickback law, and several similar state laws, prohibit the payment of any remuneration that is intended to induce physicians or others either to refer patients or to acquire or arrange for or recommend the acquisition of health care products or services. These laws constrain a medical device company’s sales, marketing and other promotional activities by limiting the kinds of business relationships and financial arrangements, including sales programs we may have with hospitals, physicians or other potential purchasers of medical devices. Other federal and state laws generally prohibit individuals or entities from knowingly presenting, or causing to be presented, claims for payment to Medicare, Medicaid or other third-party payers that are false or fraudulent, or for items or services that were not provided as claimed. From time to time, we may provide coding and billing information as product support to purchasers of our products. Anti-kickback and false claims laws prescribe civil and criminal penalties for noncompliance, which can be quite substantial including exclusion from participation in federal health care programs. A number of states have enacted laws that require pharmaceutical and medical device companies to monitor and report payments, gifts and other remuneration made to physicians and other health care professionals and health care organizations. Some state statutes, such as the one in Massachusetts, impose an outright ban on gifts to physicians. These laws are often referred to as “gift ban” or “aggregate spend” laws and carry substantial fines if they are violated. Similar legislation, known as the Physician Payments Sunshine Act, was enacted by Congress during 2014. In the event that we are found to have violated these laws or determine to settle a claim that we have done so, our business may be materially adversely affected as a result of any payments required to be made, restrictions on our future operations or actions required to be taken, damage to our business reputation or adverse publicity in connection with such a finding or settlement or other adverse effects relating thereto. Additionally, even an unsuccessful challenge or investigation into our practices could cause adverse publicity, and be costly to respond to, and thus could harm our business and results of operations.


If we are found to have violated laws protecting the confidentiality of patient health information, we could be subject to civil or criminal penalties, which could increase our liabilities, damage our reputation and harm our business.


There are a number of federal and state laws protecting the confidentiality of individually identifiable patient health information, including patient records, and restricting the use and disclosure of that protected information. In particular, the U.S. Department of Health and Human Services promulgated patient privacy rules under the Health Insurance Portability and Accountability Act of 1996, or HIPAA. These privacy rules protect medical records and other personal health information by limiting their use and disclosure, giving individuals the right to access, amend and seek accounting of their own health information and limiting most


TABLE OF CONTENTS

use and disclosures of health information to the minimum amount reasonably necessary to accomplish the intended purpose. Although weWe do not believe that we are subject to the HIPAA rules, the exact scope of these rules has not been clearly established. Ifrules. However, if we are found to be in violation of the privacy rules under HIPAA, we could be subject to civil or criminal penalties, which could increase our liabilities and harm our reputation or our business.


The use of our products could result in product liability claims that could be expensive, damage our reputation and harm our business.


Our business exposes us to an inherent risk of potential product liability claims related to the manufacturing, marketing and sale of medical devices. The medical device industry historically has been litigious, and we face financial exposure to product liability claims if the use of our products were to cause or contribute to injury or death. Our products may be susceptible to claims of injury because their use involves the electric stimulation of a patient’s nerves. Although we maintain product liability insurance for our products and other commercial insurance, the coverage limits of these policies may not be adequate to cover future claims. As sales and use of our products increase, weWe may be unable to maintain sufficient product liability or other commercial insurance on acceptable terms or at reasonable costs, and this insurance may not provide us with adequate coverage against potential liabilities. A successful claim brought against us in excess of, or outside of, our insurance coverage could have a material adverse effect on our financial condition and results of operations. A product liability claim, regardless of its merit or eventual outcome, could result in substantial costs to us, a substantial diversion of management attention and adverse publicity. A product liability claim could also harm our reputation and result in a decline in revenues and an increase in expenses.




Our products are complex in design, and defects may not be discovered prior to shipment to customers, which could result in warranty obligations or product liability or other claims, reducing our revenues and increasing our costs and liabilities.


We depend upon third parties for the manufacture of our products or components. Our products, particularly our electrodes, require a significant degree of technical expertise to produce. If these manufacturers fail to produce our products to specification, or if the manufacturers use defective materials or workmanship in the manufacturing process, the reliability and performance of our products will be compromised.

If our products contain defects that cannot be repaired quickly, easily and inexpensively, we may experience:

loss of customer orders and delay in order fulfillment;
damage to our brand reputation;
increased cost of our warranty program due to product repair or replacement;
inability to attract new customers;
diversion of resources from our manufacturing and research and development departments into our service department; and
legal action.

The occurrence of any one or more of the foregoing could harm our reputation and materially reduce our revenues and increase our costs and liabilities.


If we lose any of our officers or key employees, our management and technical expertise could be weakened significantly.


Our success largely depends on the skills, experience, and efforts of our executive officers, including Shai N. Gozani, M.D., Ph.D., our founder, Chairman, President and Chief Executive Officer, Thomas T. Higgins, our Senior Vice President and Chief Financial Officer; and Francis X. McGillin, our Senior Vice President and General Manager Consumer.Chief Commercial Officer. We do not maintain key person life insurance policies covering any of our employees. The loss of any of our executive officers could weaken our management and technical expertise significantly and harm our business.


TABLE OF CONTENTS

If we are unable to recruit, hire and retain skilled and experienced personnel, our ability to manage and expand our business will be harmed, which would impair our future revenues and profitability.


We are a small company with 4842 employees as of December 31, 2015,2018, and our ability to retain our skilled labor force and our success in attracting and hiring new skilled employees will be a critical factor in determining our future performance. We may not be able to meet our future hiring needs or retain existing personnel, particularly given the challenges faced by our business. We will face challenges and risks in hiring, training, managing and retaining engineering and sales and marketing employees. Failure to attract and retain personnel, particularly technical and sales and marketing personnel would materially harm our ability to compete effectively and grow our business.


Failure to develop or enter into relationships to sell products other than our existing products or enhance our existing products could have an adverse effect on our business prospects.


Our future business and financial success will depend, in part, on our ability to effectively market our products, such as Quell and DPNCheck, and enhance these products in response to customer demand. Developing new products and upgrades to existing and future products imposes burdens on our research and development department and our management. This process is costly, and we cannot assure you that we will be able to successfully develop new products or enhance our current products. We also may not be able to enter into relationships with other companies to sell additional products. In addition, as we develop the market for our products, future competitors may develop desirable product features earlier than we do which could make our competitors’ products less expensive or more effective than our products and could render our products obsolete or unmarketable. If our product development efforts are unsuccessful, we will have incurred significant costs without recognizing the expected benefits and our business prospects may suffer.




If we are unable to develop new products or enhance existing products, we may be unable to attract or retain customers.


Our success depends on the successful development, regulatory clearance or approval (if required), introduction and commercialization of new generations of products, treatment systems, and enhancements to and/or simplification of existing products. Quell and DPNCheck must keep pace with, among other things, the products of our competitors. We are making significant investments in long-term growth initiatives. Such initiatives require significant capital commitments, involvement of senior management and other investments on our part, which we may be unable to recover. Our timeline for the development of new products or enhancements may not be achieved and price and profitability targets may not prove feasible. Commercialization of new products may prove challenging, and we may be required to invest more time and money than expected to successfully introduce them. Once introduced, new products may adversely impact orders and sales of our existing products, or make them less desirable or even obsolete. Compliance with regulations, competitive alternatives, and shifting market preferences may also impact the successful implementation of new products or enhancements.


Our ability to successfully develop and introduce new products and product enhancements, and the revenues and costs associated with these efforts, may be affected by our ability to:

properly identify customer needs;
prove feasibility of new products in a timely manner;
educate physicians about the use of new products and procedures;
comply with internal quality assurance systems and processes timely and efficiently;
comply with regulatory requirements relating to our products, and limit the timing and cost of obtaining required regulatory approvals or clearances;
accurately predict and control costs associated with inventory overruns caused by phase-in of new products and phase-out of old products;

TABLE OF CONTENTS

price new products competitively;
manufacture and deliver our products in sufficient volumes on time, and accurately predict and control costs associated with manufacture of the products; and
meet our product development plan and launch timelines.

Even if customers accept new products or product enhancements, the revenues from these products may not be sufficient to offset the significant costs associated with making them available to customers.

Failure to successfully develop, obtain regulatory approval or clearance for, manufacture or introduce new products or to complete these processes in a timely and efficient manner could result in delays that could affect our ability to attract and retain customers, or could cause customers to delay or cancel orders, causing our backlog, revenues and operating results to suffer.


We currently compete, and may in the future need to compete, against other medical device and consumer companies with greater resources, more established distribution channels and other competitive advantages, and the success of these competitors may harm our ability to generate revenues.


We currently do, and in the future may need to, compete directly and indirectly with a number of other companies that may have competitive advantages over us. Our diagnostic devices for nerve testing compete with companies that sell traditional nerve conduction study and electromyography equipment including Cadwell Laboratories, Inc. and Natus Medical Incorporated. These companies enjoy significant competitive advantages, including:

greater resources for product development, sales and marketing;
more established distribution networks;
greater name recognition;
more established relationships with health care professionals, customers and third-party payers; and
additional lines of products and the ability to offer rebates or bundle products to offer discounts or incentives.

As we develop the market for wearable technology for chronic pain, we will likely be faced with competition from other companies that decide and are able to enter the market.market as well as competition from other forms of treatment for chronic pain. Some or all of our future competitors in the diagnostic nerve testing market and the consumer market for pain relief may enjoy competitive advantages such as those described above. If we are unable to compete effectively against existing and future competitors, our sales will decline and our business will be harmed.




Security breaches and other disruptions could compromise our information and expose us to liability, which could cause our business and reputation to suffer.


In the ordinary course of our business, we collect and store sensitive data in our data centers, on our networks, including intellectual property, our proprietary business information, and that of our customers, suppliers and business partners, and personally identifiable information of our employees. The secure processing, maintenance and transmission of this information is critical to our operations. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. Any such breach could compromise our networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, disrupt our operations, damage our reputation, and cause a loss of confidence in our products and services, which could have a material adverse effect on our business, financial condition, results of operations or cash flows.


If future clinical studies or other articles are published, or physician associations or other organizations announce positions that are unfavorable to our products, our sales efforts and revenues may be negatively affected.


Future clinical studies or other articles regarding our existing products or any competing products may be published that either support a claim, or are perceived to support a claim, that a competitor’s product is more


TABLE OF CONTENTS

accurate or effective than our products or that our products are not as accurate or effective as we claim or previous clinical studies have concluded. Additionally, physician associations or other organizations that may be viewed as authoritative or have an economic interest in nerve conduction studies and in related electrodiagnostic procedures or other procedures that may be performed using our products or in neurostimulation therapies using our devices could endorse products or methods that compete with our products or otherwise announce positions that are unfavorable to our products. Any of these events may negatively affect our sales efforts and result in decreased revenues.


As we expand into foreign markets with respect to products other than Quell, we will be affected by new business risks that may adversely impact our financial condition or results of operations.


Foreign markets represented approximately 19%12% and 19%7% of our revenues in 20152018 and 2014,2017, respectively. We are working to expand market penetration, particularly in Asia. Any such expansion will subject us to the possibility of new business risks, including:

failure to fulfill foreign regulatory requirements, if applicable, to market our products;
availability of, and changes in, reimbursement within prevailing foreign health care payment systems;
adapting to the differing business practices and laws in foreign countries;
difficulties in managing foreign relationships and operations, including any relationships that we establish with foreign distributors or sales or marketing agents;
limited protection for intellectual property rights in some countries;
difficulty in collecting accounts receivable and longer collection periods;
costs of enforcing contractual obligations in foreign jurisdictions;
recessions in economies outside of the United States;
political instability and unexpected changes in diplomatic and trade relationships;
currency exchange rate fluctuations; and
potentially adverse tax consequences.

If we are successful in introducing our products other than Quell into foreign markets, we will be affected by these additional business risks, which may adversely impact our financial condition or results of operations. In addition, expansion into foreign markets imposes additional burdens on our executive and administrative personnel, research and sales departments, and general managerial resources. Our efforts to introduce our products other than Quell into foreign markets may not be successful, in which case we may have expended significant resources without realizing the expected benefit.




Our loan and security agreement with a bank, which we refer to as our credit facility, contains financial and operating restrictions that may limit our access to credit. If we fail to comply with covenants in the credit facility, we may be required to repay any indebtedness thereunder, which may have an adverse effect on our liquidity.


Although we have not borrowed any funds under the credit facility, provisions in the credit facility impose restrictions on our ability to, among other things:

incur additional indebtedness;
create liens;
replace certain of our executive officers;
enter into transactions with affiliates;
transfer assets;

TABLE OF CONTENTS

pay dividends or make distributions on, or repurchase, our capital stock; and
merge or consolidate.

In addition, we are required to meet certain financial covenants customary with this type of credit facility, including maintaining a minimum specified tangible net worth. The credit facility also contains other customary covenants, which we may not be able to comply with in the future. Our failure to comply with these covenants may result in the declaration of an event of default and could cause us to be unable to borrow under the credit facility. In addition to preventing additional borrowings under the credit facility, an event of default, if not cured or waived, may result in the acceleration of the maturity of indebtedness outstanding under the credit facility at the time of the default, which would require us to pay all amounts outstanding. If an event of default occurs, we may not be able to cure it within any applicable cure period, if at all. If the maturity of our indebtedness is accelerated, we may not have sufficient funds available for repayment or we may not have the ability to borrow or obtain sufficient funds to replace the accelerated indebtedness on terms acceptable to us, or at all. We have not borrowed any funds under this agreement; however, as of December 31, 2015, $226,731January 24, 2019, $0.2 million of the amounts available under the agreement are restricted to support letters of credit issued in favor of our landlords.


If we sell additional shares, our stock price may decline as a result of the dilution which will occur to existing stockholders.


Until we are profitable, we will need significant additional funds to develop our business and sustain our operations. We sold shares of our common stock, convertible preferred stock and warrants in December and May 2015, June 2014 and June 2013on several occasions, and any additional sales of shares of our common stock or other securities exercisable into our common stock are likely to have a dilutive effect on some or all of our then existing stockholders. Resales of newly issued shares in the open market could also have the effect of lowering our stock price, thereby increasing the number of shares we may need to issue in the future to raise the same dollar amount and consequently further diluting our outstanding shares.


The perceived risk associated with the possible sale of a large number of shares could cause some of our stockholders to sell their stock, thus causing the price of our stock to decline. In addition, actual or anticipated downward pressure on our stock price due to actual or anticipated issuances or sales of stock could cause some institutions or individuals to engage in short sales of our common stock, which may itself cause the price of our stock to decline.


If our stock price declines, we may be unable to raise additional capital. A sustained inability to raise capital could force us to go out of business. Significant declines in the price of our common stock could also impair our ability to attract and retain qualified employees, reduce the liquidity of our common stock and result in the delisting of our common stock from The NASDAQNasdaq Stock Market LLC, or NASDAQ.

Nasdaq.




The trading price of our common stock has been volatile and is likely to be volatile in the future.


The trading price of our common stock has been highly volatile. For the five yeartwo-year period ended December 31, 2015,2018, our stock price has fluctuated from a low of $1.88$0.60 to a high of $99.33,$7.20, as adjusted for stock splits.splits during that time. The market price for our common stock will be affected by a number of factors, including:

the effectiveness of the GSK collaboration, particularly our ability to achieve development and commercialization milestones;
the denial or delay of regulatory clearances or approvals for our products under development or receipt of regulatory approval of competing products;
our ability to accomplish clinical, regulatory and other product development and commercialization milestones and to do so in accordance with our timing estimates;
changes in policies affecting third-party coverage and reimbursement in the United States and other countries;
changes in government regulations and standards affecting the medical device industry and our products;
ability of our products to achieve market success;
the performance of third-party contract manufacturers and component suppliers;

actual or anticipated variations in our results of operations or those of our competitors;
announcements of new products, technological innovations or product advancements by us or our competitors;
developments with respect to patents and other intellectual property rights;
sales of common stock or other securities by us or our stockholders in the future;
additions or departures of key scientific or management personnel;
disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our technologies;
trading volume of our common stock;
regulatory inquiries or developments affecting our products;
changes in earnings estimates or recommendations by securities analysts, failure to obtain or maintain analyst coverage of our common stock or our failure to achieve analyst earnings estimates;
public statements by analysts or clinicians regarding their perceptions of our clinical results or the effectiveness of our products;
decreases in market valuations of medical device companies; and
general market conditions and other factors unrelated to our operating performance or the operating performance of our competitors.

The stock prices of many companies in the medical device industry have experienced wide fluctuations that have often been unrelated to the operating performance of these companies. Periods of volatility in the market price of a company’s securities can result in securities class action litigation against a company. If class action litigation is initiated against us, we may incur substantial costs and our management’s attention may be diverted from our operations, which could significantly harm our business. .

Our recently implemented reverse stock split could adversely affect the market liquidity of our common stock.

On October 30, 2015, our stockholders approved an amendment to our restated certificate of incorporation, as amended, and authorized our Board of Directors, if in their judgment they deemed it necessary, to effect a reverse stock split of our common stock at a ratio


We have, in the range of 1:2past, failed to 1:4. We implemented this reverse stock split on December 1, 2015 with a ratio of 1:4. We cannot predict whether the reverse stock split will increase the market price for our common stock on a sustained basis. The history of similar stock split combinations for companies in like circumstances is varied, and we cannot predict whether:

the market price per share of our common stock after the reverse stock split will rise in proportion to the reduction in the number of shares of our common stock outstanding before the reverse stock split;
the reverse stock split will result in a per share price that will attract brokers and investors who do not trade in lower priced stocks;
the reverse stock split will result in a per share price that will increase our ability to attract and retain employees and other service providers; or
the market price per share will either exceed or remain in excess of the $1.00 minimum bid price as required by NASDAQ, or that we will otherwise meet the requirements of NASDAQ for continued inclusion for trading on The NASDAQ Capital Market.

There can be no assurance that we will be able to comply with thesatisfy certain continued listing standards of The NASDAQ Capital Market.

We cannot assure you that we will be able to comply with the standards that we are required to meet in order to maintain a listing of our common stockrequirements on The NASDAQ Capital Market. In 2015, we received two notices from the Listing Qualifications Department of the NASDAQ Stock Market,Nasdaq and we regained

compliance with respect to both of these notices before the end of fiscal year 2015. If wecould fail to continue to meet all applicable NASDAQ Capital Marketsatisfy those requirements again in the future and NASDAQ determines to delist our common stock, the delistingwhich could substantially decrease trading in our common stock and adversely affect the market liquidity of our common stock; adversely affect our ability to obtain financing on acceptable terms, if at all, for the continuation of our operations; and harm our business. Additionally, the market price of our common stock may decline further and stockholders may lose some or allliquidity and reduce our ability to raise capital.


Currently, our common stock trades on the Nasdaq Capital Market. During 2017 we received notifications from Nasdaq informing us of their investment.

certain listing deficiencies related to the minimum bid price listing requirements. Although we have since cured these deficiencies, it is possible that we could fall out of compliance again in the future. If we fail to maintain compliance with any NASDAQNasdaq listing requirements, we could be delisted and our stock would be considered a penny stock under regulations of the Securities and Exchange Commission, or SEC, and would therefore be subject to rules that impose additional sales practice requirements on broker-dealers who sell our securities. The additional burdens imposed upon broker-dealers by these requirements could discourage broker-dealers from effecting transactions in our common stock, which could severely limit the market liquidity of our common stock and your ability to sell our securities in the secondary market

The low trading volume of our common stock may adversely affect the price of our shares.

Although our common stock is listed on The NASDAQ Capital Market, our common stock has experienced low trading volume. The 50 day average trading volume through December 31, 2015 as reported by NASDAQ was approximately 120,000 shares. Limited trading volume may subject our common stock to greater price volatility and may make it difficult for investors to sell shares at a price that is attractive to them.

Anti-takeover provisions in our organizational documents and Delaware law, and the shareholder rights plan that we previously adopted in 2007, may discourage or prevent a change of control, even if an acquisition would be beneficial to our stockholders, which could affect our stock price adversely and prevent attempts by our stockholders to replace or remove our current management.


Our certificate of incorporation and bylaws contain provisions that could delay or prevent a change of control of our companyCompany or changes in our Board of Directors that our stockholders might consider favorable. Some of these provisions:

authorize the issuance of preferred stock which can be created and issued by the Board of Directors without prior stockholder approval, with rights senior to those of our common stock;
provide for a classified Board of Directors, with each director serving a staggered three-year term;
prohibit our stockholders from filling board vacancies, calling special stockholder meetings, or taking action by written consent;
provide for the removal of a director only with cause and by the affirmative vote of the holders of 75% or more of the shares then entitled to vote at an election of our directors; and
require advance written notice of stockholder proposals and director nominations.

We have also adopted a shareholder rights plan that could make it more difficult for a third party to acquire, or could discourage a third party from acquiring, us or a large block of our common stock. A third party that acquires 15% or more of our common stock could suffer substantial dilution of its ownership interest under the terms of the shareholder rights plan through the issuance of common stock to all stockholders other than the acquiring person.


In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law, which may prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock. These and other provisions in our certificate of incorporation, bylaws and Delaware law could make it more difficult for stockholders or potential acquirers to obtain control of our Board of Directors or initiate actions that are opposed by our then-current Board of Directors, including a merger, tender offer, or proxy contest involving our company.Company. Any delay or prevention of a change of control transaction or changes in our Board of Directors could cause the market price of our common stock to decline.

Chronic pain is a significant public health problem. It is defined by the National Institutes of Health as any pain lasting more than 12 weeks in contrast toweeks. This contrasts with acute pain which is a normal bodily response to injury or trauma. Chronic pain conditions include painful diabetic neuropathy, or PDN,low back pain, arthritis, fibromyalgia, sciatica, musculoskeletalneuropathic pain, cancer pain and many others. Chronic pain may be triggered by an injury or there may be an ongoing cause such as disease or illness. There may also be no clear cause. Pain signals continue to be transmitted in the nervous system over extended periods of time often leading to other health problems. These can include fatigue, sleep disturbance, decreased appetite, and mood changes which cause difficulty in carrying out important activities and contributing to disability and despair. In general, chronic pain cannot be cured. Treatment of chronic pain is focused on reducing pain and improving function. The goal is effective pain management.


Chronic pain is widespread. It affects over 100 million adults in the United States and more than 1.5 billion people worldwide. The global market for pain management drugs and devices alone was valued at $35 billion in 2012. The estimated incremental impact of chronic pain on health care costs in the United States is over $250 billion per year and lost productivity is estimated to exceed $300 billion per year.

The most common approach to chronic pain management is pain medication. This includes over-the-counter drugs (such(OTC) internal and external analgesics as Advil and Motrin), andwell as prescription drugs including anti-convulsants (such as Lyrica and Neurontin) and anti-depressants (such as Cymbalta and Elavil). Topical creams may also be used (such as Zostrix and Bengay). With severe pain, narcotic pain medications, may be prescribed (such as codeine, fentanyl, morphine, and oxycodone).both non-opioid or opioid. The approach to treatment is individualized, drug combinations may be employed, and the results are often hit or miss. Side effects and the potential for addiction are real and the risks are substantial.

Increasingly, restrictions are being imposed on access to prescription opioids. Reflecting the complexity of chronic pain and the difficulty in treating chronic pain,it, we believe that inadequate relief leads 25% to 50% of pain sufferers to turn to the over-the-counter market for supplements orseek alternatives to prescription pain medications. These alternatives include nutraceuticals, acupuncture, chiropractic care, non-prescription medications, topical creams, lotions,analgesics, electrical stimulators, dietary products, braces, sleeves, pads and other items. In total theythese pain relief products and services account for over $4approximately $20 billion in annual spending in the United States on pain relief products.

It has been cleared by the FDA for treatment of chronic intractable pain without a doctor’s prescription. Users of the device have the option of using their smartphones to automatically track and personalize their pain therapy. Quell was launched through two distribution channels: a professional channel using a direct sales force to target podiatrists, pain physicians, primary care physicians, and chiropractors who resell the product, and a direct-to-consumer channel using online marketing and lead generation. After establishing the professional and direct to consumer channels, we expanded distribution to include Amazon e-commerce sales and QVC direct response TV, or DRTV, sales. We are developing other distribution channels for broader access to the retail markets.

DPNCheck revenues for 2015, 2014, and 2013 were approximately $2.3 million, $1.8 million, and $1.3 million, respectively.

Also, the diagnosis and documentation of neuropathy provided by DPNCheck helps clarify the patient health profile which, in turn, may have a direct, positive effect on the Medicare Advantage premium received by the provider. We believe that attractive opportunities exist outside the United States, including Japan where we received regulatory approval and launched DPNCheck with our distribution partner Omron Healthcare in the third quarter of 2014; in China where we recently received regulatory approval and are working with Omron Healthcare toward commercial launch in the second half of 2016; and in Mexico where our distributor Scienta Farma received regulatory approval and initiated sales in the fourth quarter of 2015.

Our products consist of a medical device used in conjunction with a consumable electrode or biosensor. Other accessories and consumables are also available to customers. Our goal for these devices is to build an installed base of active customer accounts and distributors that regularly order aftermarket products to meet their needs. We successfully implemented this model when we started our business with the NC-stat system and applied it to subsequent product generations including ADVANCE. Our recent products, Quell, SENSUS and DPNCheck, conform to this model. Other products in our development pipeline are based on the device plus consumables business model.

Quell revenues of $2.1$10.5 million in 2015 were the largest contributor to total revenue. Quell revenues were $1.8 million, or 14.9%, below the comparable 2017 period. A significant factor contributing to the revenue growth. During 2015, 13,800decline was lower advertising spending during the first three quarters of 2018 leading up to the launch of our next generation wearable technology for chronic pain, Quell devices2.0, in September 2018. DPNCheck revenues of $4.2 million increased by $1.1 million, or 34.3% from 2017. Our legacy products contributed $1.4 million and 14,900 electrode packs with a total invoiced value of $3.1 million were shipped to Quell customers. Approximately $0.5$1.5 million of invoiced Quell shipments was made to new distribution channels where we have insufficient product return history to recognize revenue, and an additional $0.5 million in invoiced Quell shipments constituted either actual or estimate product returns by customers under our right-of-return policy and are excluded from revenue.

SENSUS, our prescription wearable device, posted shipments of about 2,900 devices and 19,800 electrode packs with total revenue of $0.6 million. This is in comparison with approximately 5,800 SENSUS devices and 17,600 electrode packs and total revenue of $0.9 million in 2014. The decline in SENSUS revenue reflects stress in the durable medical equipment distribution channel from the Medicare competitive bidding initiative, as well as sales encroachment from Quell. There were approximately 700 DPNCheck devices plus 159,000 electrodes shipped during 2015 with revenue of $2.3 million compared to approximately 680 DPN devices and 109,500 electrodes with $1.8 million in revenue in 2014. Revenues also include sales from2018 and 2017, respectively.


In 2018 we adopted revenue recognition standard ASU 2014-09 and discontinued revenue deferral under the previously mandated sell-through revenue model. Generally, the new standard results in earlier recognition of revenues. Had we not changed our ADVANCE neurodiagnostic products totaling $2.3revenue recognition policy, revenue in 2018 would have been $0.6 million in the year ended December 31, 2015, compared to $2.8 million in 2014.

Our cost of revenues increased to $4.0 million in 2015, compared to $2.6 million in 2014, primarily580 basis points or 14.5% was due to the increase in orders and shipment volumes during the comparable periods. Gross margin decreased to 45.9% in 2015 compared to 53.4% in 2014. The contraction in gross margin reflects two factors: growing Quell sales which are weighted toward lower margin devices rather than higher margin electrodes, and operating costsincreased weight of our new manufacturing facility. As we build our installed basehigh margin DPNCheck business within total revenue plus improved Quell profitability from shedding high cost distribution channels and from launch of Quell users we expect recurring electrode sales at2.0 which carries higher margins. Also, continued growth in Quell sales will improve manufacturing cost absorption contributing to margin gains.

Research and Development


Research and development expenses for 2015 and 2014 were $3.92018 increased by 46.8% from 2017 due to increased engineering consulting services costs of $1.3 million and $4.1 million, respectively. The decrease of $0.2 million primarily reflects decreased spending of $0.5 million inincreased personnel costs partially offset by increased spending of $0.3 million in consulting fees to develop Quell for launch in June 2015 and in transitioning the engineering focusrelated to Quell enhancementsproduct development and eventuallyto support the next product generation.

Revenues $5,512.8  $5,278.8  $234.0   4.4

Revenues include sales from SENSUS, our wearable therapeutic device for relief of chronic, intractable pain launched in January 2013; DPNCheck, our diagnostic test for diabetic peripheral neuropathy, or DPN, launched in Q4 2011; and our legacy ADVANCE neurodiagnostics business. Overall revenues increased by 4.4% from 2013. Revenue from our newer products, SENSUS and DPNCheck, grew by over 80% in 2014. The ADVANCE business, managed for cash flow and not growth, contracted by 25%. ADVANCE has few direct operating costs.

Revenue from SENSUS devices and consumable electrodes totaled $0.9 million in 2014 versus $0.2 million in 2013. Reflecting expanded distribution through national durable medical equipment suppliers in 2014, we shipped approximately 5,800 SENSUS devices and posted a 350% increase when compared to 1,300 devices shipped in 2013. SENSUS electrode shipments totaled approximately 17,600 in 2014 versus approximately 3,500 in 2013.

Revenue from DPNCheck increased over 40% to $1.8 million in 2014 from $1.3 million in 2013. Our Asia distribution partner, Omron Healthcare, received regulatory approval and launched DPNCheck in Japan during the third quarter of 2014, contributing positively to 2014 revenue. The United States Medicare Advantage business expanded with approximately a 50% growth in tests shipped in 2014 in comparison with 2013. Overall, there were approximately 680 DPNCheck devices and 110,000 tests shipped in 2014 in comparison with 540 devices and 85,000 tests in 2013.

ADVANCE recorded about $2.8 million in 2014 revenue in comparison to $3.8 million in 2013.

We recorded an increase in cost of revenues to $2.6 million in 2014 from $2.2 million in 2013 and a decline in our gross margin to 53.4% of revenues in 2014 from 58.4% of revenues in 2013. The decline in gross margin is primarily attributable to the SENSUS product line which comprised a greater percentage of total revenues in 2014 versus 2013, and has lower margins than our other products. The lower SENSUS margins reflect the high cost structure in the durable medical equipment sales channel which accounts for the majority of our SENSUS sales. The effect of low SENSUS margins was compounded by strong growth in that

The 2015 Equity Offerings resulted in net proceeds of approximately $16.8 million, after redemptions of certain equity instruments and after deducting financial institution discounts and fees, and other offering expenses.

In December 2015, we completed a private equity offering providing for the issuance of (i) 13,800 shares of Series C convertible preferred stock at a price of $1,000 per share, and (ii) warrants to purchase up to 10,823,528 shares of our common stock, at an exercise price of $2.30 per share. The closing of the offering occurred on December 31, 2015. The offering resulted in approximately $6.7 million in net proceeds after deducting placement agent fees and expenses and the redemption of 63,000 shares of Series B convertible preferred stock from the May 2015 public offering.

In May 2015, we completed an underwritten public offering of (i) 147,000 shares of Series B convertible preferred stock at a price of $100 per share, and (ii) five year warrants to purchase up to 3,638,250 shares of our common stock at an exercise price of $5.00 per share.

We believe that these resources, future GSK collaboration milestone payments, and the cash to be generated from expectedfuture product sales will be sufficient to meet our projected operating requirements through the second quarter of 2016.2019. Accordingly, we may need to raise additional funds to support our operating and capital needs in 2020. We continue to face significant challenges and uncertainties and, as a result, our available capital resources may be consumed more rapidly than currently expected due to (a) decreases in sales of our products and the uncertainty of future revenues from new products; (b) changes we may make to the business that affect ongoing operating expenses; (c) changes we may make in our business strategy; (d) regulatory developments affecting our existing products; (e) changes we may make in our research and development spending plans; (f) delays in the timing of achieving GSK milestones; and (f)(g) other items affecting our forecasted level of expenditures and use of cash resources.

However, pursuant to the instructions to Form S-3, we only have the ability to sell shares under the shelf registration statement, during any 12-month period, in an amount less than or equal to one-third of the aggregate market value of our common stock held by non-affiliates. If we raise additional funds by issuing equity or debt securities, either through the sale of securities pursuant to a registration statement or by other means, our existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of our existing stockholders. If we raise additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to our potential products or proprietary technologies, or grant licenses on terms that are not favorable to us. Without additional funds, we may be forced to delay, scale back or eliminate some of our sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue our operations.

Critical Accounting Policies and Estimates


Our financial statements are based on the selection and application of generally accepted accounting principles, which require us to make estimates and assumptions about future events that affect the amounts reported in our financial statements and the accompanying notes. Future events and their effects cannot be determined with certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results could differ significantly from those estimates, and any such differences may be material to our financial statements. We believe that the policies set forth below may involve a higher degree of judgment and complexity in their application than our other accounting policies and represent the critical accounting policies used in the preparation of our financial statements. If different assumptions or conditions were to prevail, the results could be materially different from our reported results. Our significant accounting policies are presented within Note 2 to our Financial Statements.


Revenue Recognition and Accounts Receivable

We recognize revenue


Revenues include product sales, net of estimated returns. Revenue is measured as the amount of consideration the Company expects to receive in exchange for product transferred. Revenue is recognized when the following criteriacontractual performance obligations have been met: persuasive evidencesatisfied and control of an arrangement exists, deliverythe product has occurred and risk of loss has passed, the seller’s pricebeen transferred to the buyer is fixed or determinable,customer. In most cases, the Company has a single performance obligation for product delivery. Product returns are estimated based on historical data and collection is reasonably assured. Revenues associated with our medical devices and

evaluation of current information.

TABLE OF CONTENTS

consumables, including single use nerve specific electrodes and other accessories are generally recognized upon shipment, assuming all other revenue criteria have been met.

Revenue recognition involves judgments, including assessments of expected returns and expected customer relationship periods. We analyze various factors, including a review of specific transactions, its historical product returns, average customer relationship periods, customer usage, customer balances, and market and economic conditions. Changes in judgments or estimates on these factors could materially impact the timing and amount of revenues and costs recognized. Should market or economic conditions deteriorate, our actual return or bad debt experience could exceed its estimate. Certain product sales are made with a 30-day or 60-day right of return. Where we can reasonably estimate future returns, we recognizes revenues upon shipment and record as a reduction of revenue a provision for estimated returns. Where we cannot reasonably estimate future returns, we defer revenues until we gain sufficient experience to estimate returns or until the right of return lapses.


Trade accounts receivable are recorded at the invoiced amount and do not bear interest.


Accounts receivable are recorded net of the allowance for doubtful accounts receivable. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We review our allowance for doubtful accounts and determine the allowance based on an analysis of customer past payment history, product usage activity, and recent communications between us and the customer. Individual customer balances which are past due and over 90 days outstanding are reviewed individually for collectability. Account balances are written-off against the allowance when we feel it is probable the receivable will not be recovered. We do not have any off-balance sheet credit exposure related to our customers.




Inventories


Inventories, consisting primarily of finished goods and purchased components, are stated at the lower of cost or market.net realizable value. Cost is determined using the first-in, first-out method. We write down inventory to its net realizable value for excess or obsolete inventory. Finished goods inventories owned by us, but stored in third party warehouses prior to order fulfillment, are disclosed separately as finished goods on consignment. The realizable value of inventories is based upon the types and levels of inventories held, forecasted demand, pricing, competition, and changes in technology. Our consumablesconsumable electrodes and biosensors have an eighteen to twenty-four month shelf life. Should current market and economic conditions deteriorate, our actual recoveries could be less than our estimates.


Recently Issued or Adopted Accounting Pronouncements


In November 2015,February 2016, the FASB issued Accounting Standards Update No. 2015-17,Balance Sheet Classification of Deferred Taxes(2016-02, Leases (Topic 842) (“ASU 2015-17)2016-02”). ASU 2015-172016-02 requires that deferred income tax liabilitieslessees recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and assets be classified as noncurrent in our balance sheet.lease liability. The standard isprovisions of this guidance are effective for public entities for annual and interim periods beginning after December 15, 2016, with early adoption permitted. ASU 2015-17 has been adopted on a prospective basis by us31, 2018, and for the year ended December 31, 2015, thus resulting in the reclassification of $45,000 of current deferred tax liabilities to noncurrent on the accompanying balance sheet. The prior reporting period was not retrospectively adjusted. The adoption of this guidance had no impact on our results of operations or cash flows.

In August 2014, the FASB issued Accounting Standards Update No. 2014-15,Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern(ASU 2014-15). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances.

We are currently evaluatingexpect to adopt ASU 2016-02, using the provisionsmodified retrospective method, upon its effective date of ASU 2014-15 and assessingJanuary 1, 2019. We anticipate the impact if any, it may have on our financial position, results of operations or cash flows.

In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), a comprehensive new revenue recognition standard that will supersedesuperseded nearly all existing revenue recognition guidance. We adopted this standard effective January 1, 2018, applying the modified retrospective method. Upon adoption, we discontinued revenue deferral under the sell-through model and commenced recording revenue upon delivery to distributors, net of estimated returns. The objectiveimpact of ASU 2014-09 is thatadoption was a company will recognize revenue when it transfers promised

ASU 2014-09 will be effective for the first quarter of 2017. An entity can elect to adopt ASU 2014-09 using one of two methods, either full retrospective adoption to each prior reporting period, or recognizing the cumulative effect of adoption at the date of initial application. We are in the process of evaluating the new standard and do not know the effect, if any, ASU 2014-09 will have on the Consolidated Financial Statements or which adoption method will be used.


ITEM 7A. Quantitative and Qualitative Disclosures about Market Risk


We do not use derivative financial instruments in our investment portfolio and have no foreign exchange contracts. Our financial instruments consist of cash and cash equivalents. We consider investments that, when purchased, have a remaining maturity of 90 days or less to be cash equivalents. The primary objectives of our investment strategy are to preserve principal, maintain proper liquidity to meet operating needs, and maximize yields. To minimize our exposure to an adverse shift in interest rates, we invest mainly in cash equivalents and short-term investments with a maturity of twelve months or less and maintain an average maturity of twelve months or less. We do not believe that a notional or hypothetical 10% change in interest rate percentages would have a material impact on the fair value of our investment portfolio or our interest income.

(1)These amounts include the aggregate grant date fair value for option awards granted during fiscal years 2018 and 2017 computed in accordance with FASB ASC Topic 718. The amount of each grant is set forth below under “Discussion of Summary Compensation Table — Long-Term Incentive Compensation.” A discussion of the assumptions used in determining grant date fair value may be found in Note 3 to our Financial Statements, included elsewhere in this Annual Report on Form 10-K.



Discussion of Summary Compensation Table

The compensation paid to the named executive officers may include salary, cash incentive compensation, and equity incentive compensation. The terms of employment agreements that we have entered into with our named executive officers are described below under “Employment Agreements and Potential Payments upon Termination or Change-in-Control.”

Cash Compensation

We pay our executive officers a base salary which we review and determine annually. As of December 31, 2018, base salaries for our executive officers are Dr. Gozani — $415,000, Mr. Higgins — $325,000, and Mr. McGillin — $357,500.

Bonus Payments

Each executive officer has an annual bonus target which is expressed as a percentage of base salary. For 2018, executive officer bonus targets as a percentage of base salary were as follows: Dr. Gozani — 62.5%; Mr. Higgins — 50%; and Mr. McGillin — 40%.

The Compensation Committee has established a process for annual assessment of corporate performance which is the foundation for decisions regarding bonus payments to executive officers. Metrics are established following approval by this Itemthe Board of Directors of the annual operating budget. These are monitored quarterly during the year and assessed after the end of the year. The Compensation Committee evaluates performance against these metrics and also applies judgment in arriving at an overall corporate performance rating or “factor”. In concept, the management bonus pool is activated by achievement of a single threshold or “gating” metric. Following activation, value is then created within the pool by achievement toward specific performance metrics.

The management pool metrics for 2018 encompassed targets for collaboration milestone attainment, sales revenue, product development, gross margins and Quell user engagement. The Compensation Committee concluded that the gating metric for 2018 had been met; however, there was inadequate progress toward other performance metrics. Consequently, a management bonus pool was not created for 2018.

Long-Term Incentive Compensation

We grant long-term equity incentive awards in the form of stock options and restricted shares to executives as part of our total compensation package. The Compensation Committee awarded in January 2018 the following equity grants comprised of stock options, to our named executive officers under our 2004 Stock Plan in the following amounts: Dr. Gozani — 75,000 options; Mr. Higgins — 37,500 options; and Mr. McGillin — 37,500 options. During 2017 there were no equity grants to the executive officers.

Stock options referred to above have a term of three years and were 100% vested on grant date. Generally, to the extent vested, each stock option is exercisable during the term of the option while the grantee is employed by us and for a period of three months thereafter, unless such termination is upon death or disability, in which case the grantee may continue to exercise the option for a period of 12 months, or for cause, in which case the option terminates immediately. Vesting of stock options is also subject to acceleration in some certain circumstances in connection with a change-in-control as described below in “Employment Agreements and Potential Payments upon Termination or Change-in-Control.”

Management Retention and Incentive Plan

Our board of directors implemented the Management Retention and Incentive Plan, or the MRIP, under which a portion of the consideration payable upon a change of control transaction, as defined in the MRIP, would be paid to our executive officers and certain other key employees. The MRIP was designed to retain these individuals during the critical, early commercialization phases of our diabetes and pain initiatives while providing management with an incentive to rapidly build corporate value potentially leading to a change of control transaction. The MRIP has been structured to work in conjunction with, and not replace, our other incentive programs such as our equity plans, severance arrangements, compensation and bonus plan, and other benefits. The MRIP is designed to provide an appropriate, market-based incentive to our executive officers and key employees which will be containedreduced over time as a result of any future equity grants to participants. Effectively, the MRIP has an embedded self-liquidation feature.



In the event of a change of control transaction, subject to the participant’s continued employment or service with us, the participant shall receive cash consideration equal to a fixed percentage of the value of the change of control transaction to be received by the Corporation or our stockholders, net of expenses. Each participant’s payment shall be reduced by (i) any payments to be made to the participant in the change of control transaction as a result of securities issued pursuant to our definitive proxy statementequity plans, (ii) the value then held by the participant of securities previously issued to the participant under our equity plans; and (iii) the then current value of shares issued to the participant under our equity plans and previously sold by the participant, excluding any founders shares.

Report of Independent Registered Public Accounting Firm


To the Board of Directors and Stockholders of NeuroMetrix, Inc.

In our opinion,


Opinion on the Financial Statements
We have audited the accompanying balance sheets of NeuroMetrix, Inc. (the Company) as of December 31, 2018 and 2017, and the related statements of operations, of changes in stockholders’ equity, and of cash flows for each of the years then ended, and the related notes and schedule (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of NeuroMetrix, Inc. atthe Company as of December 31, 20152018 and December 31, 2014,2017, and the results of its operations and its cash flows for each of the three years in the periodthen ended, December 31, 2015 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related financial statements. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.


Going Concern Uncertainty
The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has suffered recurring losses from operations, and negative cash flows from operating activities and has an accumulated deficit that raise substantial doubt about the Company’sits ability to continue as a going concern. Management’sManagement's plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

TABLE OF CONTENTS

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
We have served as the Company’s auditor since 2017.

1. Description of Business and Basis of Presentation


NeuroMetrix, Inc., or the Company, is a Delaware corporation, was founded in June 1996.commercial stage, innovation driven healthcare company combining neurostimulation and digital medicine to address chronic health conditions including chronic pain, sleep disorders, and diabetes. The Company develops wearable medical technology and point-of-care tests that help patients and physicians better manage chronic pain, nerve diseases, and sleep disorders. The Company marketshas two primary products. Quell® and SENSUS® which are is an over-the-counter wearable therapeutic devices designeddevice for reliefchronic pain. DPNCheck® is a rapid point-of-care test for diabetic neuropathy which is the most common long-term complication of chronic, intractable pain.Type 2 diabetes.

In 2018, the Company entered into a collaboration with GlaxoSmithKline ("GSK"). The GSK collaboration set up a framework for the joint development of the next generation of Quell, was commerciallyrecently launched in the United States duringin September 2018, and the second quarterassignment of 2015.areas of marketing responsibility. The Company also markets DPNCheck®, which is a quantitative nerve conduction test that is used by physicians and health care professionals to evaluate systemic neuropathies such as diabetic peripheral neuropathy, or DPN. The Company’s historical neurodiagnostic business is based oninitial term of the ADVANCETM System which is a comprehensive platform for the performance of traditional nerve conduction studies and invasive electromyography procedures and which is primarily used in physician offices and clinics.

During 2015GSK collaboration runs through 2020. Through December 31, 2018, GSK has paid the Company completed two equity offering which are detailed$14.7 million, committed to future performance milestone payments totaling up to $10.2 million, and agreed to co-fund Quell development costs starting in Note 12 to the financial statements. These financings resulted in proceeds of approximately $19.0 million after redemptions of certain equity instruments, and before fees and expenses. After deducting financial institution discounts and fees, and other expenses of the offerings, the Company realized net proceeds of approximately $16.8 million

2019.


The accompanying financial statements have been prepared on a basis which assumes that the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. The Company has suffered recurring losses from operations and negative cash flows from operating activities. At December 31, 2015,2018, the Company had an accumulated deficit of $163.6$191.0 million. These factors raise substantial doubt about the Company’s ability to continue as a going concern for the one-year period from the date of issuance of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. At December 31, 2018, the Company held cash and cash equivalents of $12.5 million as of December 31, 2015.$6.8 million. The Company believes that these resources, future GSK collaboration milestone payments, and the cash to be generated from expectedfuture product sales will be sufficient to meet its projected operating requirements through 2019. Accordingly, the second quarter of 2016.Company may need to raise additional funds to support its operating and capital needs in 2020. The Company continues to face significant challenges and uncertainties and, as a result, the Company’s available capital resources may be consumed more rapidly than currently expected due to (a) decreases in sales of the Company’s products and the uncertainty of future revenues from new products; (b) changes the Company may make to the business that affect ongoing operating expenses; (c) changes the Company may make in its business strategy; (d) regulatory developments affecting the Company’s existing products; (e) changes the Company may make in its research and development spending plans; (f) delays in the anticipated timing of GSK milestones; and (f)(g) other items affecting the Company’s forecasted level of expenditures and use of cash resources. Accordingly, the Company will need to raise additional funds to support its operating and capital needs in the third quarter of 2016 and beyond. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company intendsmay attempt to obtain additional funding through achievement of milestones under the GSK collaboration, public or private financing, collaborative arrangements with strategic partners, or through additional credit lines or other debt financing sources to increase the funds available to fund operations. However, the Company may not be able to secure such financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity or debt securities to raise additional funds, its existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders. If the Company raises additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products or proprietary technologies, or grant licenses on terms that are not favorable to the Company. Without additional funds, the Company may be forced to delay, scale back or eliminate some of its sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue its operations. If any of these events occurs, the Company’s ability to achieve its development and commercialization goals would be adversely affected.

Certain prior period amounts have been adjusted to reflect the Company's 1-for-4 reverse stock split effected December 2015 (see Note 13, Reverse Stock Split, for further details).

2. Summary of Significant Accounting Policies


Use of Estimates and Assumptions


The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make significant 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 reporting periods. Actual results could differ from those estimates.


The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances and regularly assesses these estimates, but actual results could differ materially from these estimates. Effects of changes in estimates are recorded in the period in which they occur.

2. Summary of Significant Accounting Policies - (continued)



Cash and Cash Equivalents


The Company considers all highly liquid investments with an original maturity of ninety days or less to be cash equivalents. Cash equivalents are recorded at cost which approximates fair value. The Company invests cash primarily in a money market account and other investments which management believes are subject to minimal credit and market risk.


Concentrations of Credit Risk


Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents in bank deposit accounts and trade receivables. The Company invests its funds in highly rated institutions and limits its investment in any individual account so that they do not exceed FDIC limits. The Company has not experienced significant losses related to cash and cash equivalents and does not believe it is exposed to any significant credit risks relating to its cash and cash equivalents.

Forrevenues, for the year ended December 31, 2014 one customer accounted for more than 30% of revenue. For the year ended December 31, 2013, one customer accounted for more than 10% of revenue.

2017.


The Company relies on in-house assembly and threefour third-party manufacturers to manufacture the major portion of its current products and product components. The disruption or termination of the supply of these products or a significant increase in the cost of these products from these sources could have an adverse effect on the Company’s business, financial position, and results of operations.


Inventories


Inventories, consisting primarily of finished goods and purchased components, are stated at the lower of cost or market.net realizable value. Cost is determined using the first-in, first-out method. The Company writes down inventory to its net realizable value for excess or obsolete inventory. Finished goods inventories owned by the Company, but stored in third party warehouses prior to order fulfillment, are disclosed separately as finished goods on consignment.


Fair Value


The carrying amounts of the Company’s accounts receivable, accounts payable, and accrued expenses approximate their fair value at December 31, 20152018 and 20142017 due to the short-term nature of these assets and liabilities. The Company’s cash equivalents and its warrant liability are carried at fair value determined according to the fair value hierarchy described in Note 9.

Revenue Recognition

The Company recognizes revenue when the following criteria have been met: persuasive evidence of an arrangement exists, delivery has occurred and risk of loss has passed, the seller’s price to the buyer is fixed or determinable, and collection is reasonably assured.


Revenue Recognition

TABLE OF CONTENTS


Revenues include product sales, net of estimated returns. Revenue is measured as the amount of consideration the Company expects to receive in exchange for product transferred. Revenue is recognized when contractual performance obligations have been satisfied and control of the product has been transferred to the customer. In most cases, the Company has a single product delivery performance obligation. Accrued product returns are estimated based on historical data and evaluation of current information.

Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), is a comprehensive revenue recognition standard that superseded nearly all existing revenue recognition guidance. The Company adopted this standard effective January 1, 2018, applying the modified retrospective method. Upon adoption, the Company discontinued revenue deferral under the sell-through model and commenced recording revenue upon delivery to distributors, net of estimated returns. Generally, the new standard results in earlier recognition of revenues.

2. Summary of Significant Accounting Policies - (continued)

Revenues associated with the Company’s medical devices and consumables, including single use nerve specific electrodes and other accessories are generally recognized upon shipment, assuming all other revenue criteria have been met.

Revenue recognition involves judgments, including assessments



 Upon adoption of expected returns and expected customer relationship periods. The Company analyzes various factors, including a review of specific transactions, its historical product returns, average customer relationship periods, customer usage, customer balances, and market and economic conditions. Changes in judgments or estimates on these factors could materially impact the timing and amount of revenues and costs recognized. Should market or economic conditions deteriorate, the Company’s actual return or bad debt experience could exceed its estimate. Certain product sales are made with a 30-day or 60-day right of return.

cash flows.


Accounts Receivable


Accounts receivable are recorded net of the allowance for doubtful accounts receivable. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in ourits existing accounts receivable. The Company reviews the allowance for doubtful accounts and determines the allowance based on an analysis of customer past payment history, product usage activity, and recent communications with the customer. Individual customer balances which are past due and over 90 days outstanding are reviewed individually for collectability. Account balances are written-off against the allowance when the Company feels it is probable the receivable will not be recovered. The Company does not have any off-balance sheet credit exposure related to ourits customers.

Allowance for doubtful accounts was $25,000 as of December 31, 2018 and 2017. 


Income Taxes


The Company records income taxes using the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases, and operating loss and tax credit carryforwards. The Company’s financial statements contain certain deferred tax assets, which have arisen primarily as a result of operating losses, as well as other temporary differences between financial and tax accounting. In accordance with the provisions of the Income Taxes topic of the Codification, the Company is required to establish a valuation allowance if the likelihood of realization of the deferred tax assets is reduced based on an evaluation of objective verifiable evidence. Significant management judgment is required in determining the Company’s provision for income taxes, the Company’s deferred tax assets and liabilities and any valuation allowance recorded against those net deferred tax assets. The Company evaluates the weight of all available evidence to determine whether it is more likely than not that some portion or all of the net deferred income tax assets will not be realized.


Utilization of the NOL and research and development credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that have occurred previously or that could occur in the future, as provided by Section 382 of the Internal Revenue Code of 1986, as well as similar state provisions. Ownership changes may limit the amount of NOL and tax credit carryforwards that can be utilized to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. If the Company has experienced a change of control, utilization of its NOL or tax credits carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the NOL or research and development credit carryforwards before utilization. Subsequent ownership changes could further impact the limitation in future years. Further, until a study is completed and any limitation known, no amounts are being presented as an uncertain tax position. A full valuation allowance has been provided against the

Company’s NOL carryforwards and research and development credit carryforwards and, if an adjustment is required, this adjustment would be offset by an adjustment to the valuation allowance. Thus, there would be no impact to the balance sheet or statement of operations if an adjustment were required.


Management performed a two-step evaluation of all tax positions, ensuring that these tax return positions meet the “more likely than not” recognition threshold and can be measured with sufficient precision to determine the benefit recognized in the financial statements. These evaluations provide management with a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements certain tax positions that the Company has taken or expects to take on income tax returns.


Research and Development


Costs incurred in research and development are expensed as incurred. Included in research and development costs are wages, benefits, product design consulting, and other operating costs such as facilities, supplies, and overhead directly related to the Company’s research and development efforts.



NeuroMetrix, Inc. 

Notes to Financial Statements

2. Summary of Significant Accounting Policies - (continued)


Collaboration income

Collaboration income is recognized within Other Income when contractual performance obligations, outside the ordinary activities of the Company, have been satisfied and control has been transferred to a collaboration partner. Collaboration income for each performance obligation is based on relative fair value of the overall transaction price. A deferred collaboration income liability is recorded when payments are received prior to satisfaction of performance obligations. The company recognized $12,255,704 of collaboration income in 2018 and recorded $1,956,522 of deferred collaboration income liability as of December 31, 2018.

Product Warranty Costs


The Company accrues estimated product warranty costs at the time of sale which are included in cost of sales in the statements of operations. The amount of the accrued warranty liability is based on historical information such as past experience, product failure rates, number of units repaired, and estimated cost of material and labor. The liabilities for product warranty costs of $10,484$129,837 and $1,784$127,361 at December 31, 20152018 and 2014,2017, respectively, are included in accrued expenses in the accompanying balance sheets.


Fixed Assets and Long-Lived Assets


Fixed assets are recorded at cost and depreciated using the straight-line method over the estimated useful life of each asset. Expenditures for repairs and maintenance are charged to expense as incurred. On disposal, the related assets and accumulated depreciation are eliminated from the accounts and any resulting gain or loss is included in the Company’s statement of operations. Leasehold improvements are amortized over the shorter of the estimated useful life of the improvement or the remaining term of the lease.


The Company periodically evaluates the recoverability of its fixed assets and other long-lived assets whenever events or changes in circumstances indicate that an event of impairment may have occurred. This periodic review may result in an adjustment of estimated depreciable lives or asset impairment. When indicators of impairment are present, the carrying values of the asset are evaluated in relation to the assets operating performance and future undiscounted cash flows of the underlying assets. If the future undiscounted cash flows are less than their book value, an impairment may exist. The impairment is measured as the difference between the book value and the fair value of the underlying asset. Fair values are based on estimates of the market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk.


Accounting for Stock-Based Compensation


Stock-based compensation cost is generally recognized ratably over the requisite service period. The Company uses the Black-Scholes option pricing model for determining the fair value of its stock options and amortizes its stock-based compensation expense using the straight-line method. The Black-Scholes model requires certain assumptions that involve judgment. Such assumptions are the expected share price volatility, expected life of options, expected annual dividend yield, and risk-free interest rate (See Note 3 — Stock-Based Compensation and Stockholders’ Equity)Compensation).

Net Loss per Common Share

Basic net loss per common share is computed by dividing net loss applicable to common stockholders by the weighted average number of common shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic net

Net Income (Loss) per common share. DilutedCommon Share

Basic and dilutive net lossincome (loss) per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period plus the dilutive effect of the weighted average number of outstanding instruments suchwere as options, warrants, restricted stock, and preferred stock. Because the Company has reported a net loss for all periods presented, diluted loss per common share is the same as basic loss per common share, as the effect of utilizing the fully diluted share count would have reduced the net loss per common share. Therefore, in calculating net lossfollows:

Recently Issued or Adopted Accounting Pronouncements


In November 2015,February 2016, the FASB issued Accounting Standards Update No. 2015-17,Balance Sheet Classification of Deferred Taxes(2016-02, Leases (Topic 842) (“ASU 2015-17)2016-02”). ASU 2015-172016-02 requires that deferred income tax liabilitieslessees recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and assets be classified as noncurrent in the Company’s balance sheet.lease liability. The standard isprovisions of this guidance are effective for public entities for annual and interim periods beginning after December 15, 2016, with early adoption permitted. ASU 2015-17 has been adopted on a prospective basis by the Company31, 2018, and for the year ended December 31, 2015, thus resulting in the reclassification of $45,000 of current deferred tax liabilities to noncurrent on the accompanying consolidated balance sheet. The prior reporting period was not retrospectively adjusted. The adoption of this guidance had no impact on the Company’s results of operations or cash flows.

In August 2014, the FASB issued Accounting Standards Update No. 2014-15,Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern(ASU 2014-15).

The Company is evaluating the provisions of ASU 2014-15 and assessing the impact, if any, it may have on financial position, results of operations or cash flows.

In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance. The objective of ASU 2014-09 is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will be effective for the first quarter of 2017. An entity can elect to adopt ASU 2014-092016-02, using onethe modified retrospective method, upon its effective date of two methods, either full retrospective adoption to each prior reporting period, or recognizingJanuary 1, 2019.

regarded as a compensatory plan. For the years ended December 31, 20152018 and 20142017 the Company issued 15,44322,804 and 3,68111,583 shares of its common stock, respectively, under the Amended and Restated 2010 ESPP and the 2010 ESPP, respectively.ESPP. As of December 31, 2015,2018, there were 19,792127,775 remaining shares to be issued under the Amended and Restated 2010 ESPP.


The Company uses the Black-Scholes option pricing model for determining the fair value of shares of common stock issued or to be issued under the 2010 ESPP and the Amended and Restated 2010 ESPP. The following assumptions are used in determining fair value: The risk-free interest rate assumption is based on the United States Treasury’s constant maturity rate for a six month term (corresponding to the expected option term) on the date the option was granted. The expected dividend yield is zero because the Company does not currently pay dividends nor expects to do so during the expected option term. An expected term of six months is used based on the duration of each plan offering period. The volatility assumption is based on a consideration of stock price volatility over the most recent period of time corresponding to the expected term and is also based on expected future stock price volatility.


The weighted average grant-date fair value of stock options used in the calculation of stock-based compensation expense in the accompanying statement of operations for the years ended December 31, 2015, 2014,2018 and 20132017 is calculated using the following assumptions:

Risk-free interest rate  1.3 – 1.7%   1.4 – 1.8%   1.4 – 1.7%

Risk-free interest rate2.2- 3.0% 1.8- 2.1%
Expected dividend yield
 
Expected option term3 - 5 years
 5 years
Volatility70.0% 70.0%

The risk-free interest rate assumption is based on the United States Treasury’s constant maturity rate for a three or five year term (corresponding to the expected option term) on the date the option was granted. The expected dividend yield is zero as the Company does not currently pay dividends nor expects to do so during the expected option term. The expected option term of three to five years is estimated based on an analysis of actual option exercises. The volatility assumption is based on daily historical volatility during the time period that corresponds to the expected option term and expected future stock price volatility. The pre-vesting forfeiture rate is based on the historical and projected average turnover rate of employees.

Expected to vest options are determined by applying the pre-vesting forfeiture rate to the total outstanding options. Aggregate intrinsic value represents the total pre-tax intrinsic value (the aggregate difference between the closing stock price of the Company’s common stock as of December 31, 2015,2018, as applicable, and the exercise price for the in-the-money options) that would have been received by the option holders if all the in-the-money options had been exercised on December 31, 2015.

The weighted average per share grant-date fair values of options granted during 2015, 2014,2018 and 20132017 was $2.95, $4.24,$1.71 and $4.08,$2.37, respectively.


The aggregate intrinsic value of options issued or exercised during 2015, 2014,2018 and 20132017 was $0.


Total unrecognized stock-based compensation costs related to non-vested stock options was $288,000,$244,422, which related to 214,813494,101 shares with a per share weighted fair value of $11.18$4.08 as of December 31, 2015.2018. This unrecognized cost is expected to be recognized over a weighted average period of approximately 2.12.0 years.

Stock options granted to non-employees are recorded at fair value and adjusted to market over the vesting period. The Company determines fair value using the Black-Scholes option pricing model, an expected term equal to the option term, a risk-free interest rate corresponding to the expected term, a stock price volatility over the most recent period of time corresponding to the expected term and also based on expected future stock price volatility, and a dividend yield of zero. There were no options granted to non-employees during the years ended December 31, 2015, 2014 or 2013.

Beginning in 2010, certain employees have been granted restricted stock. There were no restricted stock grants in 2015 and 2014. During 2013, the Company granted 500 shares of restricted stock. The restricted stock vested based on continued employment. The fair value of restricted stock is calculated based on the closing sale price of the Company’s common stock on the date of issuance.

This amount includes tax benefits of $3.9$2.5 million and $71,000$75,482 attributable to NOL and tax credit carryforwards, respectively, that result from the exercise of employee stock options.

2019.


In accordance with the provisions of the Income Taxes topic of the Codification, the Company has evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets, which are comprised principally of net operating losses. Management has determined that it is more likely than not that the Company will not recognize the benefits of federal and state deferred tax assets and, as a result, a valuation allowance of approximately and $43.8$35.0 million and $38.6$35.3 million has been established at December 31, 20152018 and 2014,2017, respectively. In December 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was enacted and included changes which reduced the federal corporate tax rate to 21% effective January 1, 2018. Deferred income tax assets and liabilities are measured using enacted tax laws and rates applicable to the periods in which differences are expected to reverse. Accordingly, deferred tax assets and liabilities have been remeasured as of December 31, 2017 and the effect of the remeasurement has been reflected in the provision for income taxes for the year ended December 31, 2017. Utilization of the NOL and research and development credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that have occurred previously or that could occur in the future, as provided by Section 382 of the Internal Revenue Code of 1986, as well as similar state provisions. Ownership changes may limit the amount of NOL and tax credit carryforwards that can be utilized to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain

shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. If the Company has experienced a change of control, utilization of its NOL or tax credits carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the NOL or research and development credit carryforwards before utilization. Subsequent ownership changes could further impact the limitation in future years. Further, until a study is completed and any limitation known, no amounts are being presented as an uncertain tax position. A full valuation allowance has been provided against the Company’s NOL carryforwards and research and development credit carryforwards and, if an adjustment is required, this adjustment would be offset by an adjustment to the valuation allowance. Thus, there would be no impact to the balance sheet or statement of operations if an adjustment were required.

The Company has not recorded any amounts for unrecognized tax benefits as of December 31, 2018 or 2017. The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company is subject to examination by federal and state jurisdictions, where applicable. There are currently no pending income tax examinations. The Company’s tax years are still open under statute from December 31, 2015 to the present. Earlier years may be examined to the extent that tax credit or net operating loss carryforwards are used in future periods. The Company’s policy is to record interest and penalties related to income taxes as part of its income tax provision.

Under the Waltham Lease, the landlord was responsible for making certain improvements to the leased space at an agreed upon cost to the landlord. The landlord and the Company mutually agreed to make improvements in excess of the agreed upon landlord cost, and the landlord billed that excess cost to the Company as additional rent. This additional rent of $275,961 was included in the net calculation of lease payments, so that rent expense is recognized on a straight-line basis over the remaining term of occupancy.

9. Fair Value Measurements

The Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (the “Codification”) defines fair value, establishes a framework for measuring fair value in applying generally accepted accounting principles, and expands disclosures about fair value measurements. This Codification topic identifies two kinds of inputs that are used to determine the fair value of assets and liabilities: observable and unobservable. Observable inputs are based on market data or independent sources while unobservable inputs are based on the Company’s own market assumptions. Once inputs have been characterized, this Codification topic requires companies to prioritize the inputs used to measure fair value into one of three broad levels. Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values identified by Level 2 inputs utilize observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. Fair values identified by Level 3 inputs are unobservable data points and are used to measure fair value to the extent that observable inputs are not available. Unobservable inputs reflect the Company’s own assumptions about the assumptions that market participants would use at pricing the asset or liability.


The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis for the periods presented and indicates the fair value hierarchy of the valuation techniques it utilized to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable such as quoted prices, interest rates, and yield curves. Fair values determined by Level 3 inputs are unobservable data points for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability.

The amount of the deemed dividend totaled $8,332,212. As of December 31, 2015, all of the newly issued Series C Preferred Stock were outstanding.

In May 2015, the Company completed an underwritten public offering (the “May 2015 Offering”) of (i) 147,000 shares of Series B Preferred Stock (the “Series B Preferred Stock”) at a price of $100 per share,$2.8 million and (ii) five year warrants to purchase up to 3,638,250 shares of common stock with an exercise price of $5.00 per share. The May 2015 Offering resulted in approximately $14.7$4.0 million in gross proceeds, before deducting underwriting discounts and commission and expenses. In conjunction with the 2015 Offering, approximately $3.2 million of the proceeds were used to repurchase the outstanding Series A-4 preferred shares from the 2014 Offering (described below). Net proceeds from the May 2015 Offering, after deducting underwriting discount and commissions and offering expenses and repurchase of outstanding Series A-4 preferred shares, were approximately $10.1 million.

of 610,929 shares of common stock. During the third quarter of 2015, 28,170 shares of the Series B Preferred Stock were converted into a total of 697,207 shares of common stock. During the fourth quarter of 2015, 24,000 shares of the Series B Preferred Stock were converted into a total of 594,000 shares of common stock and 63,000 shares of the Series B Preferred Stock were repurchased with the proceeds of the December 2015 Offering. As of December 31, 2015, 7,146 shares of the Series B Preferred Stock were outstanding.

The terms and conditions of the Series B Preferred Stock were evaluated based on the guidance of the Derivatives and Hedging topic of the Codification to determine if the conversion feature was an embedded derivative requiring bifurcation. It was concluded that bifurcation was not required because the conversion feature was clearly and closely related to the Series B Preferred Stock. The conversion price at which shares of Series B Preferred Stock were convertible into shares of common stock was determined to be lower than the fair value of common stock at the date of entering into the agreement with the underwriter. This “in-the-money” beneficial conversion feature, or BCF, required separate recognition and measurement of its intrinsic value (i.e., the amount of the increase in value that holders of Series B Preferred Stock would realize upon conversion based on the value of the conversion shares on the date of the underwriting agreement). Because there was not a stated redemption date for the shares of Series B Preferred Stock, the BCF was recognized as a deemed dividend attributable to the Series B Preferred Stock and reflected as an adjustment in the calculation of earnings per share. The amount of the BCF totaled $4,140,446 for the May 2015 Offering.

The Company determined that equity classification was appropriate for the warrants issued in the December 2015 Offering and the May 2015Q1 2017 Offering, following guidance in the Derivatives and Hedging topic of the Codification. In making this equity classification determination, the Company noted the warrants may only be settled in shares of common stock and had no requirements to be settled in registered shares when exercised. The fair value of the 5five year warrants issued in connection with the December 2015 Offering was estimated to be $6.0 million on the offering date using date using a Black-Scholes model with the following assumptions: stock price of $1.98, exercise price of $2.30, expected volatility of 70.9%, risk free interest rate of 1.75%, expected term of five years, and no dividends. The fair value of the 1 year warrants issued in connection with the December 2015 Offering was estimated to be $2.2 million on the offering date using date using a Black-Scholes model with the following assumptions: stock price of $1.98, exercise price of $2.30, expected volatility of 65.7%, risk free interest rate of 0.65%, expected term of one year, and no dividends. The fair value of the warrants issued in connection with the May 2015 Offering was estimated to be $3.2 million on the offering date using utilizing quoted prices (unadjusted) in active markets. The relative fair values were recorded as equity.

In June 2014, the Company entered into a securities purchase agreement (the “2014 Offering”) for the issuance of (i) 166,150 shares of common stock at a price of $8.16 per share, (ii) 2,621.859 shares of Series A-3 Preferred Stock (the “Series A-3 Preferred Stock”) at a price of $1,000 per share, (iii) 4,022.357 shares of Series A-4 Preferred Stock (the “Series A-4 Preferred Stock,” and together with the Series A-3 Preferred Stock, the “Preferred Stock”) at a price of $1,000 per share, and (iv) five year warrants to purchase up to 980,392 shares of common stock with an exercise price of $8.16 per share. The 2014 Offering resulted in approximately $8.0 million in gross proceeds, before deducting expenses. Net proceeds from the 2014 Offering were approximately $7.9 million.

In the 2014 Offering, each share of Preferred Stock had a stated value of $1,000 and was convertible at the option of the holder into the number of shares of common stock determined by dividing the stated value by the conversion price of $8.16, which is subject to adjustment as provided in each applicable Certificate of Designation for the Preferred Stock. The Preferred Stock had no dividend rights, liquidation preference or other preferences over common stock and had no voting rights except as provided in each applicable Certificate of Designation for the Preferred Stock and as required by law. The 2014 Offering BCF measurement was limited by the transaction proceeds which had been allocated to the Preferred Stock. The BCF was recognized as a deemed dividend attributable to the Preferred Stock and reflected as an

adjustment in the calculation of earnings per share in the quarter ended September 30, 2014. The amount of the BCF totaled $2,955,668 for the 2014 Offering.

The Series A-3 Preferred Stock was convertible into an aggregate of 321,306 shares of common stock and the Series A-4 Preferred Stock was convertible into an aggregate of 492,936 shares of common stock. During June 2014, 204 shares of the Series A-3 Preferred Stock were converted into a total of 25,000 shares of common stock. During July 2014, the remaining 2,417.859 shares of the Series A-3 Preferred Stock were converted into 296,306 shares of common stock. During October 2014, 408 shares of the Series A-4 Preferred Stock were converted into a total of 50,000 shares of common stock. During February 2015, 408 shares of the Series A-4 Preferred Stock were converted into a total of 50,000 shares of common stock. During May 2015, the remaining 3,206.357 shares of the Series A-4 Preferred Stock were repurchased by the Company at a price of $1,000 per share. Total consideration of $3.2 million for the repurchase of the Series A-4 convertible preferred stock and warrants was allocated to the convertible preferred stock and warrants based on their relative fair value. A BCF has been recognized as a return of capital from the preferred shareholders to the common shareholders attributable to the repurchase of 3,206.357 Series A-4 preferred stock and related beneficial embedded conversion feature, and is reflected as an adjustment in the calculation of earnings per share.

The Company continues to revalue unexercised warrants from the 2014 Offering at each reporting period over the life of the warrants using the Black-Scholes model and the changes in the fair value of the warrants were recognized in the Company's statement of operations. The warrants issued in connection with the 2014 Offering were within the scope of the Derivatives and Hedging topic of the Codification. This Codification topic requires issuers to classify as liabilities (or assets under certain circumstances) financial instruments which require an issuer to settle in registered shares. As the warrants are required to be settled in registered shares when exercised, the Company reflected the warrants as a liability in the balance sheet.

The fair value of the warrants issued in connection with the 2014 Offering was estimated to be $4.4$3.5 million on the offering date using a Black-Scholes model with the following assumptions: stock price of $8.00,$4.96, exercise price of $8.16,$5.60, expected volatility of 67.48%70.2%, risk free interest rate of 1.64%2.04%, expected term of five5 years, and no dividends.

13. Reverse Stock Split

The Company’s common stock is quoted on the NASDAQ Capital Market under the symbol “NURO.” One of the requirements for continued listing on the NASDAQ Capital Market is maintenance of a minimum closing bid price of $1.00 per share. Because the Company’s common stock had been trading below a price of $1.00 per share, and was subject to delisting from The NASDAQ Stock Market LLC, or NASDAQ as a result, on December 1, 2015, the Company filed a Certificate of Amendment to its Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware, to effect a 1-for-4 reverse stock split of its common stock, or the Reverse Stock Split. This action had previously been approved by the Company’s stockholders at the Company’s special meeting held on October 30, 2015. As a result of the Reverse Stock Split, every four shares of the Company’s pre-reverse split common stock were combined and reclassified into one share of its common stock. No fractional shares were issued in connection with the Reverse Stock Split. Stockholders who otherwise would have been entitled to receive a fractional share in connection with the Reverse Stock Split received a cash payment in lieu thereof. The par value and other terms of the common stock were not affected by the Reverse Stock Split.

The Company’s shares outstanding immediately prior to the Reverse Stock Split totaled 13,785,239, which were adjusted to 3,446,274 shares outstanding as a result of the Reverse Stock Split. The Company’s common stock began trading at its post-Reverse Stock Split price at the beginning of trading on December 2, 2015. Share, per share, and stock option amounts for all periods presented within the financial statements contained in the Annual Report on Form 10-K including the December 31, 2014 Balance Sheet amounts for common stock and additional paid-in capital have been retroactively adjusted to reflect the Reverse Stock Split.

On December 16, 2015, the Company received a letter from NASDAQ indicating that it had regained compliance with the minimum bid price requirement under NASDAQ Listing Rule 5550(a)(2) for continued listing on The NASDAQ Capital Market. The Company’s common stock continues to be listed on NASDAQ.

14. Management Retention and Incentive Plan


The Company has adopted the Management Retention and Incentive Plan (the “Plan”), under which a portion of the consideration payable upon a change in control transaction, as defined in the Plan and its amendments, would be paid in cash to certain executive officers and key employees and recorded as compensation expense within the Statement of Operations during the period in which the change of control transaction occurs. The Plan is structured to work in conjunction with, and not replace, the Company’s other incentive programs and is designed to provide market-based incentives which will be reduced over time by any future equity grants to participants.
