ITEM 1. BUSINESS

Our Business — An Overview

NeuroMetrix is a commercial stage, innovation driven healthcare company combining bioelectrical and digital medicine to address chronic health conditions including chronic pain, sleep disorders, and diabetes. Our business is fully integrated with in-house capabilities spanning product development, manufacturing, regulatory affairs and compliance, sales and marketing, and customer support. We derive revenues from the sale of medical devices and after-market consumable products and accessories. Our products are sold in the United States and selected overseas markets, and are cleared by the U.S. Food and Drug Administration, or FDA, and regulators in foreign jurisdictions where appropriate. We have two principal product lines:

• Wearable neuro-stimulation therapeutic devices

• Point-of-care neuropathy diagnostic tests

Our core expertise in biomedical engineering has been refined over nearly two decades of designing, building and marketing medical devices that stimulate nerves and analyze nerve response for diagnostic and therapeutic purposes. We created the market for point-of-care nerve testing and were first to market with sophisticated, wearable technology for management of chronic pain. We also have an experienced management team and Board of Directors. 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 to acute pain which is a normal bodily response to injury or trauma. Chronic pain conditions include painful diabetic neuropathy, or PDN, arthritis, fibromyalgia, sciatica, musculoskeletal 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.

1

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. Estimated out-of-pocket spending in the United States on chronic pain is $20 billion per year.

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 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.

Reflecting 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 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 for over $4 billion in annual spending in the United States on pain relief products.

High frequency 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, both of which require surgery and have attendant risks. Non-invasive approaches to neuro-stimulation (transcutaneous electrical nerve stimulation, or TENS) have achieved limited efficacy in practice due to device limitations, ineffective dosing and low patient compliance.

Collaboration with GSK Consumer Healthcare

On January 12, 2018, we entered into an Asset Purchase Agreement with Novartis Consumer Health S.A., an affiliate of GlaxoSmithKline, or GSK, pursuant to which we agreed to sell to GSK our Quell technology for markets outside of the United States, including certain patents and related assets. The purchase price for the assets being sold pursuant to the Asset Purchase Agreement is equal to $5 million. NeuroMetrix retains exclusive ownership of Quell technology in the U.S. market. NeuroMetrix and GSK also entered into a Development and Services Agreement on January 12, 2018, pursuant to which we agreed to provide services related to the development, regulatory approval and commercialization of the Quell technology for markets outside of the U.S. Pursuant to the Development and Services Agreement, GSK has agreed to make contingent payments of up to $21.5 million to NeuroMetrix upon the occurrence of certain development and commercialization milestones. In addition, GSK and NeuroMetrix will co-fund development of next-generation Quell technology during an initial period of 2018 through 2020, with subsequent annual renewals by mutual agreement. NeuroMetrix agreed not to compete with GSK with respect to the development and commercialization of the Quell technology and device outside of the U.S. until the tenth anniversary of the date of termination or expiration without renewal of the Development and Services Agreement.

In connection with the Asset Purchase Agreement, NeuroMetrix entered into a Contribution Agreement on December 22, 2017 with Quell Intellectual Property Corp., LLC, a newly formed Delaware limited liability company that was formed as a special purpose entity, and contributed certain intellectual property rights related to the Quell technology. Following the closing of the transactions contemplated by the Contribution Agreement and Asset Purchase Agreement, NeuroMetrix and GSK each now own a 50% interest in Quell Intellectual Property Corp, LLC. Quell Intellectual Property Corp., LLC entered into two exclusive license agreements with NeuroMetrix relating to rights to Quell intellectual property for use in the U.S. and in markets outside the U.S. Under the terms of an Assignment Agreement entered into on January 12, 2018, NeuroMetrix assigned the ex-U.S. license agreement to GSK. We refer herein to these agreements as the GSK Collaboration.

Our Strategy

2

There are large and important unmet medical needs in chronic pain treatment. Prescription pain medications and over-the-counter therapies are often inadequate 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 well positioned to make neuro-stimulation widely 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 four and half years and Quell, our over-the-counter, or OTC, wearable device for pain relief which was launched in the second quarter of 2015 and builds upon the core SENSUS neuro-stimulation technology.

Our primary objective is revenue growth with margin expansion and declining cash consumption. We expect this to be led by the successful market adoption of Quell. We also expect an important contribution to revenue from DPNCheck, our rapid, accurate diagnostic test for diabetic peripheral neuropathy.

Our key business strategies include:

Driving Commercial Adoption of Key Proprietary Products.

• Quell, our OTC wearable device for pain relief, was made commercially available in the United States during the second quarter of 2015. Following commercial launch through the end of 2017, approximately 140,500 Quell devices plus electrodes and accessories were shipped to customers. Quell revenues for the years ended December 31, 2017 and 2016 were approximately $12.4 million and $7.4 million, respectively. Quell utilizes OptiTherapy, our proprietary non-invasive neuro-stimulation technology to provide relief from chronic intractable pain, such as nerve pain due to diabetes, fibromyalgia, arthritic pain, and lower back and leg pain. This advanced wearable device is lightweight and can be worn during the day while active, and at night while sleeping. It has been cleared by the FDA for treatment of chronic pain without a doctor’s prescription. Users of the device have the option of using their smartphones to control pain therapy and to track sleep, activity, gait and therapy parameters. Quell is distributed in the United States via e-commerce, via direct response television, and via select retail merchandisers, and health care professionals. Distribution is supported by television promotion and digital advertising to expand product awareness.

• DPNCheck, our diagnostic test for peripheral neuropathies, was made commercially available in the fourth quarter of 2011. DPNCheck revenues for the years December 31, 2017 and 2016 were approximately $3.1 million and $2.5 million, respectively. Our US 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. We believe that attractive opportunities exist outside the United States including Japan where DPNCheck is marketed by our distribution partner Fukuda Denshi; in China where we initiated sales in 2017 via Omron Beijing Ltd.; and in Mexico where DPNCheck is marketed by Scienta Farma.

Research and Development Innovation for Competitive Advantage  Our research and development, or R&D, team developed 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 responsible for maintaining and expanding Quell’s competitive technological advantage, addressing opportunities to reduce Quell cost of goods sold, 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.

Our Business Model

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 commercial objective is to build an installed base of active, satisfied 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 the ADVANCE system. Our more recently developed products, Quell, SENSUS and DPNCheck, conform to this model.

Primary Marketed Products

Quell

3

Quell is a wearable device for relief of chronic intractable pain, such as nerve pain due to diabetes and lower back problems. It incorporates our OptiTherapy technology, a collection of proprietary approaches designed to optimize the clinical efficacy of nerve stimulation. These include high power electrical stimulation hardware with precise control, algorithms that automatically determine therapeutic stimulation intensity and compensate for nerve desensitization, and automated detection of user sleep and appropriate adjustment of stimulation level. Quell is comprised of (1) an electronic device carried in a neoprene band that is worn on the upper calf and (2) an electrode that attaches to the device and is the interface between the device and the skin. The device is lightweight and can be worn during the day while active, and at night while sleeping. It has been cleared by the FDA for treatment of chronic intractable pain and is available OTC. Users of the device have the option of using their smartphones to control pain therapy and to track sleep and therapy parameters. The device was made commercially available in June 2015. In an independent post-market clinical study of Quell initiated by NeuroMetrix, 81% of subjects reported an improvement in their chronic pain and health, and 67% reported a reduction in their use of pain medications. To encourage persons with chronic pain to try Quell, we offer a 60-day trial period during which the product can be returned for a full refund. To date, product returns have averaged approximately 25%. We estimate, over time, we will see product returns in the range of 20% to 25%, as indicated by the results of the post-market clinical study. The addressable market opportunity for Quell in the United States is estimated to be 19 million chronic pain sufferers. Quell is available via e-commerce, via direct response television, via select retail merchandisers, and via health care professionals. Distribution is supported by television promotion and digital advertising to expand product awareness. Following commercial launch through 2017 approximately 140,500 devices plus consumables and accessories were shipped to customers.

DPNCheck

DPNCheck is a fast, accurate, and quantitative nerve conduction test that is used to evaluate systemic neuropathies such as diabetic peripheral neuropathy, or DPN. It is designed to be used by primary care physicians, endocrinologists, podiatrists and other clinicians at the point-of-care to objectively detect, stage, and monitor DPN. The device measures nerve conduction velocity and response amplitude of the sural nerve, a nerve in the lower leg and ankle. These parameters are widely recognized as sensitive and specific biomarkers of DPN. DPNCheck is comprised of: (1) an electronic hand-held device and (2) a single patient use biosensor. In addition, we provide users with PC-based software that links to the device via a USB connection. This PC software allows physicians to generate reports and manage their sural nerve conduction data.

DPNCheck is a modified version of our previously marketed NC-stat nerve testing device that has the same clinical indications with respect to DPN. The modified device costs less than the original device, but has the same functionality with respect to sural nerve testing. More than 2.7 million patient studies have been performed using our NC-stat technology and there have been approximately 7.3 million nerve tests. It has been the subject of many published studies, including several studies specifically addressing the accuracy and clinical utility of the device in assessment of DPN. DPNCheck shipments commenced in late 2011 and approximately 4,000 devices plus consumables have been placed with customers through December 31, 2017.

ADVANCE System

Our legacy neurodiagnostics business is the ADVANCE System, which is a comprehensive platform for the performance of traditional nerve conduction studies. The ADVANCE System is comprised of: (1) the ADVANCE device and related modules, (2) various types of electrodes, and (3) a communication hub that enables the physician’s office to network their device to their personal computers and our servers for data archiving, report generation, and other network services. The ADVANCE System is most commonly used with proprietary nerve specific electrode arrays. These electrode arrays combine multiple individual electrodes and embedded microelectronic components into a single patient-use disposable unit. We currently market seven different nerve specific electrode arrays but do not actively market the ADVANCE device.

Historically, the ADVANCE System was marketed to a broad range of physician specialties including neurologists, orthopedic surgeons, primary care physicians, and endocrinologists, and utilized for a variety of different clinical indications including assessment of carpal tunnel syndrome, or CTS, low back and leg pain, and DPN. It is most commonly used in the assessment of CTS. Numerous papers have been published on the use of this technology in this clinical application. More than 2.7 million patient studies have been performed using our NC stat technology and there have been approximately 7.3 million nerve tests, including 1.6 million sural nerve tests. As of December 31, 2017, we had an installed base of approximately 300 active customers using our ADVANCE System.

The following chart summarizes our previously marketed products and currently marketed products.

At December 31, 2017, two customers accounted for 66% of accounts receivable and one customer accounted for 19% of revenue.

Geographic Information

Substantially all of our assets, revenues, and expenses for 2017 and 2016 were located in or derived from operations in the United States. In addition, we have had sales through distributors in Europe, Asia, the Middle East, Mexico and various other regions. During 2017 and 2016, international revenues accounted for approximately 7% and 12%, respectively, of our total revenues.

Sales, Marketing, and Distribution

Quell is distributed in the United States via e-commerce including the Company’s website www.quellrelief.com and Amazon, via direct response television including QVC, via retail merchandisers including Target, CVS, Best Buy, Bed Bath and Beyond and others, and via health care professionals. Distribution is supported by television promotion and digital advertising designed to expand product awareness.

Our U.S. sales efforts for DPNCheck 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. We believe that attractive growth opportunities exist outside the United States, including Japan where DPNCheck is sold by our distribution partner Fukuda Denshi; in China where DPNCheck is sold by our distribution partner Omron Beijing Ltd.; and in Mexico where DPNCheck is sold by our distribution partner Scienta Farma.

Our installed base of ADVANCE accounts is supported by our customer service department. We are not actively pursuing new ADVANCE customers. Internationally, ADVANCE sales and account support is handled by our network of independent distributors.

Quell sales and marketing efforts are led by our Senior Vice President and Chief Commercial Officer. Sales and marketing efforts for DPNCheck and ADVANCE are led by our Senior Vice President, General Manager, Diagnostics.

We provide technical, clinical, and business practices training for our commercial employees including sales and marketing, and customer service.

Manufacturing and Supply

We perform final assembly and servicing of our Quell and DPNCheck devices at our manufacturing facility in Massachusetts. The ADVANCE device which is no longer in production but for which we continue to sell accessories, is serviced by us. Outside suppliers provide us the sub-assemblies and components that we use in manufacturing Quell and DPNCheck, as well as our consumable biosensors/electrodes. We maintain alternative suppliers for some but not all of the sub-assemblies and key components. Consumable biosensors/electrodes are manufactured to our specifications by two long standing suppliers. In outsourcing, we target companies that meet FDA, International Organization for Standardization, or ISO, and other quality standards supported by internal policies and procedures. Supplier performance is maintained and managed through a corrective action program ensuring all product requirements are met or exceeded. Following the receipt of products or product components from our third-party manufacturers, we conduct the necessary inspection, final assembly, packaging, and labeling at our manufacturing facility. We believe that our manufacturing relationships minimize our capital investment, provide us with manufacturing expertise, and help control costs.

Sunburst EMS, Inc. has been manufacturing devices and providing sub-assemblies to us since 2005. Sunburst currently manufactures sub-assemblies for Quell and DPNCheck at a facility in Massachusetts.

MC Assembly, Inc., a contract manufacturer, has manufactured sub-assemblies for Quell, at a facility in Massachusetts since 2016.

Johnson Medtech, LLC, or Johnson, has been manufacturing ADVANCE electrodes for us since 1999, currently at a facility in Massachusetts. Johnson is planning to shift production in the first quarter of 2018 to another Johnson facility located in Ohio.

Katecho, Inc., a full service original equipment manufacturer, or OEM, specializing in medical and cosmetic devices, manufactures biosensors for use with our DPNCheck device and electrodes for use with our Quell devices under normal commercial terms contained in our purchase orders. Katecho manufactures electrodes at its facility in Iowa.

We and our third-party manufacturers are registered with the FDA and subject to compliance with FDA quality system regulations. We are also ISO registered and undergo frequent quality system audits by a European agency. Our ADVANCE System and DPNCheck are cleared for marketing within the United States, Canada, and the European Union. DPNCheck is also cleared for marketing in Japan, China and Mexico. Our neuro-stimulation systems for chronic pain, Quell and SENSUS, are cleared for marketing in the United States, Canada,  the European Economic Area, and Australia. Our facility is subject to periodic inspections by regulatory authorities, and may undergo compliance inspections conducted by the FDA and corresponding state agencies. As a registered device manufacturer, we will undergo regularly scheduled FDA quality system inspections. However, additional FDA inspections may occur if deemed necessary by the FDA.

Research and Development

We believe that we have research and development (R&D) capability that is unique to the industry with over two decades of experience in developing diagnostic and therapeutic devices involving the stimulation and measurement of nerve signals for clinical purposes. This group 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 our founder and Chief Executive Officer who holds both M.D. and Ph.D. degrees and who also coordinates the clinical programs that are supported by NeuroMetrix.

R&D efforts currently encompass the following areas:

• Quell Innovation.  Quell utilizes our proprietary wearable intensive nerve stimulation (WINS) technology to provide relief from chronic pain which can encompass lower back problems, fibromyalgia, arthritis, painful diabetic neuropathy

6

and others. Quell is unique among OTC neuro-stimulation products in its clinical indications, technology, personalization and digital health features. Our R&D efforts to date have provided us first-to-market competitive advantage. We anticipate that success will attract competition and that we must continually innovate to maintain a leadership position. Our product development strategy is focused on the annual delivery of new features that enhance usability and biometric tracking. These include form factor changes, electrode improvements and expanding digital health integration. We intend to strengthen our intellectual property position with the development of additional know-how and a growing body of patent applications.

• Cost of Goods Sold (COGS) Improvement.  We have identified specific opportunities to reduce Quell COGS, with both near-term and longer-term initiatives underway. Lower COGS would improve gross margins, thereby providing pricing flexibility, which may be necessary to expand Quell adoption. These COGS initiatives involve R&D support as well as investment in engineering design and equipment.

• 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, in Japan and in Mexico. DPNCheck received regulatory approval in China and Omron Beijing, Ltd has initiated commercial activities in that 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 expect that an expanding body of evidence from clinical studies will continue to build Quell credibility among health care professionals and support our marketing efforts. As an example, in 2015 we 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 was directly relevant to Quell marketing and reinforced the need to continue to build the clinical foundation for Quell. We have underway several small-scale clinical studies to assess efficacy in key pain indications, reduction in prescription opioid use in cancer patients, back pain, and improvements in sleep, among others.

Research and development expenses were approximately $3.5 million and $4.4 million for 2017 and 2016, respectively.

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.

In a study published last year in the Journal of Pain 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 pain interference with sleep and walking ability. Four external studies have been carried out in 2017.

• Quell TENS band for Chemotherapy-Induced Peripheral Neuropathy (CIPN), A Feasibility Study (University of Rochester Medical Center, University of Rochester, Rochester, NY). This open label study is designed to evaluate Quell efficacy, assessed by pain relief and continued device use, in subjects with CIPN. Preliminary results were presented at the American Pain Society meeting May 17-20, 2017, in Pittsburgh, PA. Among subjects completing the first 6 weeks of the study, 73% decided to continue using their Quell device. In addition, statistically significant reductions in pain, tingling, cramping and numbness were observed. A large-scale randomized sham-controlled study is planned in 2018 by the principal investigator at the University of Rochester.

• Quell Opioid Reduction and Pain Relief in Patients with Cancer (Scripps Translational Science Institute, Scripps Health, San Diego, CA). This randomized sham-controlled study is designed to evaluate opioid use reduction in patients with various forms of cancer pain. The study is completed and preliminary results are expected in early 2018.

• Efficacy of the Quell Wearable Device for Chronic Low Back Pain (Brigham and Women's Hospital, Harvard Medical School, Boston, MA). This randomized controlled study is designed to evaluate pain relief and quality of life improvements in subjects with low back pain using Quell compared to control subjects on standard therapy. The study is fully enrolled and data collection is near completion. Study results are expected in 2018.

• Prospective Validation of Quell Sleep/Wake Classification and Periodic Leg Movement Detection (Massachusetts General Hospital, Harvard Medical School, Boston, MA). This study is designed to compare Quell sleep tracking to gold standard polysomnography. The study is fully enrolled and results are expected in early 2018.

7

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

• At the PAINWeek National Conference held September 5-9, 2017, in Las Vegas, NV, two scientific posters were presented.  Results of a poster titled “Ambulatory Stride Variability Measured by a Wearable Device is a Biomarker for Chronic Pain Severity” suggested that automatic Quell gait measurements are an objective biomarker for pain severity. In another poster titled “Self-Reported Weather Sensitivity Stratifies Subjects with Chronic Pain”, Quell users with and without self-reported weather sensitivity showed distinct demographic and clinical characteristics, indicating that subjects with self-reported weather sensitivity express a different chronic pain phenotype than those who report weather insensitivity.

• At the 16^th Annual Pain Medicine Meeting held November 16-18, 2017, in Orlando, FL, two scientific posters were presented. In a poster titled “Will People with Severe Chronic Pain Utilize Wearable Pain Relief Technology?”, analysis of results of demographic and clinical characteristics of Quell users suggested that older adults were as likely to adopt wearable and digital health technology as overall chronic pain sufferers. In another poster titled “Daily Utilization of Surface Neurostimulation is Associated with Reduced Pain Interference with Sleep, Activity and Mood in Subjects with Chronic Pain”, study results suggested that optimal reduction in pain intensity and pain interference with sleep, activity, and mood is most likely achieved with daily device use.

Competition

We believe there is no direct competition to our Quell wearable neuro-stimulation 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 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.

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 for over $4 billion in annual spending in the United States on pain relief products.

High frequency 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 require surgery and have attendant risks. Non-invasive approaches to neuro-stimulation (transcutaneous electrical nerve stimulation, or TENS) have achieved limited efficacy in practice due to device limitations, ineffective dosing and low patient compliance. We believe that our 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 place Quell in a unique neuro-stimulation category. There are numerous manufacturers of transcutaneous electrical nerve stimulation devices including widely marketed over-the-counter TENS such as Sanofi’s IcyHot SmartRelief, Omron PM3030 and 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 physical 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, 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, 2017, we had 38 issued U.S. patents, six issued foreign patents, and 36 patent applications, including 26 U.S. applications, and 25 foreign applications. Our wearable therapeutic products have six issued U.S. utility patents, two issued foreign patents, and three issued U.S. design patents plus 37 utility and design patent applications. The foreign patents for wearable therapeutics have been assigned to GSK under the terms of the GSK Collaboration. For our DPNCheck diagnostic device, seven utility patents were issued that cover the core technology and there are six additional utility patent applications.

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

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, and Wearable Pain Relief Technology. 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 2018 Physicians Fee Schedule published by CMS includes CPT 95905 for nerve conduction studies performed with pre-configured electrode arrays such as are used with the DPNCheck device and the ADVANCE System.

9

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. 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 sales effort for DPNCheck on the Medicare Advantage managed care market segment.

We believe that our 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 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 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 and ADVANCE will depend upon, among other things, our customers receiving, and our potential 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, their adoption and our future product sales will be materially adversely affected.”

FDA and Other Governmental Regulation

FDA Regulation

Our products are medical devices subject to extensive regulation by the 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 on the basis of the amount of risk associated with the medical device and the controls deemed necessary to reasonably ensure their safety and effectiveness:

• Class I, requiring general controls, including labeling, device listing, reporting and, for some products, adherence to good manufacturing practices through the FDA’s quality system regulations and pre-market notification;

• Class II, requiring general controls and special controls, which may include performance standards and post-market surveillance; and

• Class III, requiring general controls and pre-market approval, or PMA, which may include post-approval conditions and post-market surveillance.

Before being introduced into the market, our products must obtain market clearance or approval through the 510(k) pre-market notification process, the de novo review process or the PMA process, unless they qualify for an exemption from these processes. 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.”

510(k) Pre-Market Notification Process

10

To obtain 510(k) clearance, we must submit a pre-market notification demonstrating that the proposed device is substantially equivalent to a legally marketed Class I or II medical device or to a Class III device marketed prior to May 28, 1976 for which the FDA has not required the submission of a PMA application. In some cases, we may be required to perform clinical trials to support a claim of substantial equivalence. If clinical trials are required, we must 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. It generally takes three months from the date of the pre-market notification submission to obtain a final 510(k) decision, but it can be significantly longer.

After a medical device receives 510(k) clearance, 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) clearance or could require de novo classification or PMA. The FDA allows each company to make this determination, but the FDA can review the decision. If the FDA disagrees with a company’s decision not to seek FDA authorization, the FDA may require the company to seek 510(k) clearance or PMA. 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 Review Process

If a previously unclassified new medical device does not qualify for the 510(k) pre-market notification process because there 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 for de novo classification through what is called the de 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 medical device or to a Class III device marketed prior to May 28, 1976 for which the FDA has not required the submission of a PMA application, it has been placed into Class III. After receiving this letter, the company, within 30 days, must submit to the FDA a request for a risk based down classification of the device from Class III to Class I 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 devices for the same intended use. If a product is classified as Class II through the de novo review process, then that device may serve as a predicate device for subsequent 510(k) pre-market notifications.

PMA Process

If a medical device does not qualify for the 510(k) pre-market notification process and is not eligible for clearance through the de novo review process, a company must submit a PMA application. The PMA requires more extensive pre-filing testing than is required in the 510(k) 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 PMA process can take one to three years or longer, from the time the PMA application is filed with the FDA. The PMA process requires the company to prove that the 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 event of modifications to the device, including to its labeling, intended use or indication, or its manufacturing process that affect safety and effectiveness.

Post-Approval Obligations

After a device is placed on the market, numerous regulatory requirements continue to apply. These include:

11

• 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;

• 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 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 which 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 cause inspections by FDA to review a manufacturer’s facilities and their 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 which 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. 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.

Manufacturing Facilities

12

Our facility, and the facilities utilized by Sunburst and MC Assemblies, Inc., our contract sub-assembly 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 accepted by the FDA and we believe that we and our contract manufacturers 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

We were founded in 1996 as a science-based health care company. Our focus had been 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. 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 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-care nerve testing, a market which we created, was met with resistance in some sectors 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 was such that we were unable to secure broad coverage among private payers, which was 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 $55.3 million. We reported revenue for our legacy Neurodiagnostics business of $1.5 million and $2.0 million in 2017 and 2016, respectively. We currently manage this business to optimize cash flow.

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

We have incurred significant cumulative net losses since our inception. Our net losses for the years ended December 31, 2017 and 2016, were approximately $12.9 million and $14.9 million, respectively. At December 31, 2017, we had an accumulated deficit of $191.3 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 the 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 $4.0 million as of December 31, 2017. We believe that these resources, the $5.0 million received in January 2018 under the GSK Collaboration, 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 into the fourth quarter of 2018. However, the timing of GSK milestone achievement and the amount of our future product sales is difficult to predict and actual sales may not be in line with our forecasts.

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 and will be dependent on funding our operations through 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. These circumstances raise substantial doubt about our ability to continue as a going concern. As a result of this uncertainty and the substantial doubt about our ability to continue as a going concern as of December 31, 2017, the report of our independent registered public accounting firm in this Annual Report on Form 10-K for the year ended December 31, 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; (e) changes in our research and development spending plans; and (f) other items affecting our forecasted level of expenditures and use of cash resources. Accordingly, we may need to raise additional funds to support our future operating and capital needs in the fourth quarter of 2018. We may attempt to obtain additional funding through 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 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

15

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 140,500 Quell devices since then. Additionally, DPNCheck, which was launched in 2011, 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. 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 create market demand for Quell through online marketing efforts, direct response television and other retail channels;

• manufacturing issues with Quell or our other products;

• inability to increase adoption of DPNCheck within the Medicare Advantage market;

• unfavorable market response to our product in international 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 for Quell and/or 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 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.

We have recently entered into the GSK Collaboration, and our ability to work together with GSK to achieve the desired results of the collaboration is unproven.

In January 2018, we entered into an Asset Purchase Agreement with GSK, pursuant to which we agreed to sell to GSK our Quell technology for markets outside of the United States, including certain patents and related assets. We retain exclusive ownership of Quell technology in the U.S. market. We and GSK also entered into a Development and Services Agreement on January 12, 2018, pursuant to which we agreed to provide services related to the development, regulatory approval and commercialization of the Quell technology for markets outside of the U.S. We have agreed not to compete with GSK with respect to the development and commercialization of the Quell technology and device outside of the U.S. until the tenth anniversary of the date of termination or expiration without renewal of the Development and Services Agreement.

16

Pursuant to the Development and Services Agreement, GSK has agreed to make contingent payments of up to $21.5 million to us upon the occurrence of certain development and commercialization milestones, plus amounts for co-funded next-generation Quell development. As we have just recently entered into these agreements, we do not have a history of working together with GSK on which we can base the likelihood of success of this collaboration. If we are unable to achieve the anticipated milestones, we will not receive the anticipated contingent payments, and our business could be materially and adversely affected.

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 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, 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.

17

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 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 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, 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, and to fully manufacture devices 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 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 with 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 SENSUS 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 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

18

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 new products, including Quell, during the initial production ramp-up phase. If any materially adverse changes in our relationships with these manufacturers occur, our ability to supply our customers will be severely limited until we are able to engage an alternate manufacturer 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, 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 requests information in connection with an FTC review for compliance of our representations about Quell with Sections 5 and 12 of the FTC Act. We are in the process of producing documents and information in response to the CID. 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.

19

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 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;

• 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 began to expire in 2015, and our issued utility patents 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

20

in 2017. Although the patent protection for material aspects of these products covered by the claims of the patents were lost at that time, we have additional patents and patent applications directed to other novel inventions that will have patent terms extending beyond 2017. 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. 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.

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-

21

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 use and disclosures of health information to the minimum amount reasonably necessary to accomplish the intended purpose. We do not believe that we are subject to the HIPAA rules. 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, we 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

22

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 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.

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 41 employees as of December 31, 2017, 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.

23

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;

• 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 be faced with competition from other companies that decide and are able to enter the 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.

24

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 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 7% and 12% of our revenues in 2017 and 2016, 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.

25

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;

• 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 February 8, 2018, $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 convertible preferred stock and warrants on several occasions, including July 2017, January 2017 and June 2016, 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 Nasdaq Stock Market LLC, or 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 two-year period ended December 31, 2017, our stock price has fluctuated from a low of $1.45 to a high of $18.88, as adjusted for stock 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 announced in January 2018, particularly the achievement of 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;

26

• 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.

There can be no assurance that we will be able to comply with the continued listing standard 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 stock on the Nasdaq Capital Market. On February 2, 2017, we received a notice from the Listing Qualifications Department of the Nasdaq Stock Market indicating that, for the preceding 30 consecutive business days, the bid price for our common stock had closed below the minimum $1.00 per share required for continued inclusion on The Nasdaq Capital Market under Nasdaq Listing Rule 5550(a)(2). The notification letter stated that pursuant to Nasdaq Listing Rule 5810(c)(3)(A) the Company would be afforded 180 calendar days, or until August 1, 2017, to regain compliance with the minimum bid price requirement.

We regained compliance with this requirement on May 25, 2017, after implementing a reverse split of our common stock. If we fail to continue to meet all applicable Nasdaq Capital Market requirements in the future and Nasdaq determines to delist our common stock, the delisting 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 all of their investment.

If we fail to maintain compliance with any Nasdaq 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.

.

27

Anti-takeover provisions in our organizational documents and Delaware law, and the shareholder rights plan that we 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 Company 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. 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.

We do not intend to pay cash dividends.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all available funds and any future earnings for use in the operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future. In addition, the terms of our credit facility preclude us from paying any dividends. As a result, capital appreciation, if any, of our common stock will be our stockholders’ sole source of potential gain for the foreseeable future.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

Our headquarters and engineering activities are located in an approximately 12,000 square foot leased facility in Waltham, Massachusetts and our manufacturing and fulfillment activities are located in a 6,000 square foot leased facility in Woburn, Massachusetts. We believe these facilities will be adequate for our needs during the foreseeable future.

ITEM 3. LEGAL PROCEEDINGS

While we are not currently a party to any material legal proceedings, we could become subject to legal proceedings in the ordinary course of business. We do not expect any such potential items to have a significant impact on our financial position.

ITEM 4. MINE SAFETY DISCLOSURES

Not applicable.

Overview

NeuroMetrix is a commercial stage, innovation driven healthcare company combining bioelectrical and digital medicine to address chronic health conditions including chronic pain, sleep disorders, and diabetes. Our business is fully integrated with in-house capabilities spanning product development, manufacturing, regulatory affairs and compliance, sales and marketing, and customer support. We derive revenues from the sale of medical devices and after-market consumable products and accessories. Our products are sold in the United States and selected overseas markets, and are cleared by the U.S. Food and Drug Administration, or FDA, and regulators in foreign jurisdictions where appropriate. We have two principal product lines:

• Wearable neuro-stimulation therapeutic devices

• Point-of-care neuropathy diagnostic tests

Our core expertise in biomedical engineering has been refined over nearly two decades of designing, building and marketing medical devices that stimulate nerves and analyze nerve response for diagnostic and therapeutic purposes. We created the market for point-of-care nerve testing and were first to market with sophisticated, wearable technology for management of chronic pain. We also have an experienced management team and Board of Directors.

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 to acute pain, which is a normal bodily response to injury or trauma. Chronic pain conditions include painful diabetic neuropathy, or PDN, arthritis, fibromyalgia, sciatica, musculoskeletal 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. Estimated out-of-pocket spending in the United States on chronic pain is $20 billion per year.

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 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.

Reflecting 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 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 for over $4 billion in annual spending in the United States on pain relief products.

High frequency 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

30

signal transmission through the central nervous system. This therapeutic approach is available through deep brain stimulation and through implantable spinal cord stimulation, both of which require surgery and have attendant risks. Non-invasive approaches to neuro-stimulation (transcutaneous electrical nerve stimulation, or TENS) have achieved limited efficacy in practice due to device limitations, ineffective dosing and low patient compliance.

Quell, our OTC wearable device for pain relief, was made commercially available in the United States during the second quarter of 2015. Following commercial launch through the end of 2017, approximately 140,500 Quell devices plus electrodes and accessories were shipped to consumers. Quell utilizes our patented 100% drug-free neuro-stimulation technology to provide relief from chronic intractable pain, such as nerve pain due to diabetes, fibromyalgia, arthritic pain, and lower back and leg pain. This advanced wearable device is lightweight and can be worn during the day while active, and at night while sleeping. It has been cleared by the U.S. Food and Drug Administration (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 control pain therapy and to track sleep, activity, gait and therapy parameters. Quell is distributed in North America via e-commerce, including the Company’s website (www.quellrelief.com) and Amazon, via direct response television including QVC, via retail merchandisers including Target, CVS, Best Buy, Bed Bath and Beyond and others, and via health care professionals such as pain management physician practices and podiatry practices. Distribution is supported by television promotion to expand product awareness.

DPNCheck, our diagnostic test for peripheral neuropathies, was made commercially available in the fourth quarter of 2011. DPNCheck revenues for 2017 and 2016 were approximately $3.1 million and $2.5 million, respectively. 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. We believe that attractive opportunities exist outside the United States, including Japan where DPNCheck is marketed by our distribution partner Fukuda Denshi; in China where we initiated sales in 2017 via OMRON Beijing Ltd.; and in Mexico where DPNCheck is marketed by Scienta Farma.

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 commercial objective 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 more recently developed products, Quell, SENSUS and DPNCheck, conform to this model. Other products in our development pipeline are based on the device plus consumables business model.

Results of Operations

Comparison of Years Ended December 31, 2017 and December 31, 2016

Revenues

The following table summarizes our revenues:

	Years Ended December 31,
	2017		2016		Change		% Change
	(in thousands)
Revenues	$	17,092.3	$	12,027.5	$	5,064.8	42.1	%

During 2017 total revenues increased by approximately $5.1 million, or 42.1%, from 2016.

Quell revenues were approximately $12.4 million and $7.4 million in 2017 and 2016, respectively. This increase of approximately $5.0 million was the largest contributor to overall revenue growth.

During 2017, 80,930 Quell devices and 121,402 electrode reorder packages were shipped to Quell customers. In the comparative period of 2016, we shipped 45,726 Quell devices and 52,658 electrode reorder packages.

31

In 2017, DPNCheck revenue of approximately $3.1 million reflected sales of 647 DPNCheck devices plus 189,050 biosensors. This compared with approximately $2.5 million in revenue in 2016 reflecting sales of 630 DPNCheck devices and 188,925 biosensors.

ADVANCE neurodiagnostic products contributed approximately $1.5 million in revenue for 2017, as compared to approximately $2.0 million in 2016. SENSUS, our prescription wearable device for chronic pain had revenues of approximately $0.1 million in 2017 and 2016.

Cost of Revenues and Gross Profit

The following table summarizes our cost of revenues and gross profit:

	Years Ended December 31,
	2017		2016		Change		% Change
	(in thousands)
Cost of revenues	$	10,235.5	$	7,113.0	$	3,122.5	43.9	%
Gross profit	$	6,856.8	$	4,914.5	$	1,942.3	39.5	%

Our cost of revenues increased to approximately $10.2 million in 2017, compared to approximately $7.1 million in 2016, primarily due to the increase in orders and shipment volumes during the comparable periods. Gross margin decreased to 40.1% in 2017 compared to 40.9% in 2016. The contraction in gross margin conforms to the early stages of our plan for building a business with a high level of recurring revenue from an installed product base of medical devices. It reflects two factors: growing Quell sales which are heavily weighted toward lower margin devices rather than higher margin electrodes, and operating costs of our new manufacturing facility. As we build our installed base of Quell users we expect growth in recurring electrode sales at higher margins. Also, we expect continued growth in Quell sales to improve manufacturing cost absorption, contributing to future margin gains.

Operating Expenses

The following table summarizes our operating expenses:

	Years Ended December 31,
	2017		2016		Change			% Change
	(in thousands)
Operating expenses:
Research and development	$	3,497.6	$	4,394.4	$	(896.8	)	(20.4	)%
Sales and marketing	10,751.9		10,855.4		(103.5		)	(1.0	)%
General and administrative	5,689.9		4,872.7		817.2			16.8	%
Total operating expenses	$	19,939.4	$	20,122.5	$	(183.1	)	(0.9	)%

Research and Development

Research and development expenses for 2017 and 2016 were approximately $3.5 million and $4.4 million, respectively. The decrease of approximately $0.9 million primarily related to decreased spending of $1.2 million in consulting fees used to develop the next product generation of Quell.

Sales and Marketing

Sales and marketing expenses decreased to approximately $10.8 million in 2017 from approximately $10.9 million in 2016. The approximately 0.1 million decrease in spending was primarily attributable to a reduction of approximately $0.5 million in personnel, travel and trade show expenses partially offset by an approximately $0.5 million increase in TV advertising, on-line advertising and paid search.

32

General and Administrative

General and administrative expenses increased by approximately $0.8 million to $5.7 million in 2017 compared to $4.9 million in the prior year. The increase was primarily due to banking and legal related professional fees which increased by approximately $0.8 million.

Interest Income

Interest income was approximately $14,900 and $19,100 during 2017 and 2016, respectively. Interest income was earned from investments in cash equivalents.

Change in fair value of warrant liability

The change in fair value of warrant liability was $0.2 million and $0.3 million during 2017 and 2016, respectively. The lower 2017 change in valuation primarily reflects the effects of the Q3 2017 financing exchange of warrant liability for Series F Preferred Stock of $40,772 (See “Liquidity and Capital Resources”). During 2017, we repurchased and retired all outstanding liability classified warrants.

Net loss per common share applicable to common stockholders, basic and diluted

The net loss per common share applicable to common stockholders, basic and diluted, was $11.60 and $58.21 for 2017 and 2016, respectively.

Net loss per common share applicable to common stockholders in 2017 of $11.60 reflected a deemed dividend attributable to preferred stockholders of $4.0 million, or $2.38 per share, related to our Q1 2017 equity offering; a deemed dividend attributable to preferred stockholders of $2.8 million, or $1.66 per share, related to our Q3 2017 equity offering; and our 2017 net loss reported in our Statement of Operations of $12.9 million, or $7.56 per share. Per share amounts are calculated using 1,701,481 weighted average shares outstanding in 2017.

Net loss per common share applicable to common stockholders in 2016 of $58.21 reflected a deemed dividend attributable to preferred stockholders of $19.8 million, or $33.24 per share, related to our June 2016 equity offering; and our 2016 net loss reported in our Statement of Operations of $14.9 million, or $24.97 per share. Per share amounts are calculated using 597,130 weighted average shares outstanding in 2016.

Liquidity and Capital Resources

Our principal source of liquidity is our cash and cash equivalents. As of December 31, 2017, cash and cash equivalents totaled $4.0 million. Our ability to generate revenue to fund our operations will largely depend on the success of our wearable therapeutic products for chronic pain and our diagnostic products for neuropathy. A low level of market interest in Quell or DPNCheck, an accelerated decline in our neurodiagnostics consumables sales, or unanticipated increases in our operating costs would have an adverse effect on our liquidity and cash generated from operations. The following table sets forth information relating to our cash and cash equivalents:

	December 31, 2017		December 31, 2016		Change		% Change
	(in thousands)
Cash and cash equivalents	$	4,043.7	$	3,949.1	$	94.6	2.4	%

During 2017 our cash and cash equivalents remained essentially unchanged from 2016 reflecting the net proceeds of $12.9 million provided by our 2017 equity offerings, offset by $12.7 million of net cash used in operations and $0.2 million used in investing activities.

33

In the third quarter of 2017, we completed a private equity offering providing for the issuance of 7,000 shares of Series F convertible preferred stock at a price of $1,000 per share and resetting the conversion price of 14,052.93 shares of Series D convertible preferred stock and 7,000 shares of Series E convertible preferred stock to $2.63 per share. This offering resulted in approximately $6.6 million in net proceeds after deducting fees and expenses.

In the first quarter of 2017, we completed a private equity offering providing for the issuance of i) 7,000 shares of Series E convertible preferred stock (the “Series E Preferred Stock”) at a price of $1,000 per share, and (ii) warrants to purchase up to 1,250,000 shares of Common Stock at an exercise price of $5.60 per share. The offerings resulted in approximately $6.3 million in net proceeds after deducting fees and expenses.

The Company is party to a Loan and Security Agreement, or the credit facility, with a bank. As of December 31, 2017 the credit facility permitted the Company to borrow up to $2.5 million on a revolving basis. The credit facility was subsequently amended, most recently on January 17, 2018, and extended until January 15, 2019. Amounts borrowed under the credit facility will bear interest equal to the prime rate plus 0.5%. Any borrowings under the credit facility will be collateralized by the Company’s cash, accounts receivable, inventory, and equipment. The credit facility also includes traditional lending and reporting covenants. These include certain financial covenants applicable to liquidity that are to be maintained by the Company. As of December 31, 2017, the Company was in compliance with these covenants and had not borrowed any funds under the credit facility. However, $0.2 million of the amount under the credit facility is restricted to support letters of credit issued in favor of our facilities landlords. Consequently, the amount available for borrowing under the credit facility as of December 31, 2017 was approximately $2.3 million.

In managing working capital, we focus on two important financial measurements as presented below:

	Years Ended December 31,
	2017	2016
Days sales outstanding (days)	19	23
Inventory turnover rate (times per year)	7.8	6.1

Customer payment terms generally vary from payment-on-order for Quell e-commerce sales to 120 days from invoice date. Both days sales outstanding and inventory turnover improved during 2017.

The following sets forth information relating to sources and uses of our cash:

	Years Ended December 31,
	2017			2016
	(in thousands)
Net cash used in operating activities	$	(12,652.4	)	$	(15,080.3	)
Net cash used in investing activities	(163.1		)	(100.5		)
Net cash provided by financing activities	12,910.0			6,667.0

Our operating activities used approximately $12.7 million for the year ended December 31, 2017 primarily attributable to our net loss of $12.9 million. This loss included non-cash credits of approximately $0.2 million for revaluing outstanding warrants at fair value. In addition, operating activities included increases in accrued expenses of $0.6 million and accrued compensation of $0.5 million, partially offset by increases in prepaid and other current assets of $0.9 million.

During the year ended December 31, 2017, our investing activities reflected $0.2 million spent for the acquisition of fixed assets, primarily related to production system upgrades.

We held cash and cash equivalents of $4.0 million as of December 31, 2017. Under the terms of the GSK Collaboration entered in January 2018, we received payment of $5.0 million, the agreement by GSK to make contingent payments of up to $21.5 million upon the achievement of certain development and commercialization milestones, plus the amounts for co-funded next generation Quell development during an initial period of 2018 through 2020. We believe that these resources and the cash to be generated from expected product sales will be sufficient to meet our projected operating requirements into the fourth quarter of 2018. We continue to face significant challenges and uncertainties and, as a result, our available capital resources

34

may be consumed more rapidly than currently expected due to (a) decreases in sales of our 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; and (f) other items affecting our forecasted level of expenditures and use of cash resources. Accordingly, we may need to raise additional funds to support our operating and capital needs in the fourth quarter of 2018. These factors raise substantial doubt about our 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. We may attempt to obtain additional funding through public or private financing, collaborative arrangements with strategic partners, or through additional credit lines or other debt financing sources. However, we may not be able to secure such financing in a timely manner or on favorable terms, if at all. We filed a shelf registration statement on Form S-3 with the SEC covering shares of our common stock and other securities for sale, giving us the opportunity to raise funding when needed or otherwise considered appropriate at prices and on terms to be determined at the time of any such offerings. 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. If any of these events occurs, our ability to achieve our development and commercialization goals would be adversely affected.

At December 31, 2017, the Company has federal and state net operating loss carryforwards ("NOL") of approximately $145.2 million and $51.6 million, respectively, as well as federal and state tax credits of approximately $1.5 million and $1.1 million, respectively, which may be available to reduce future taxable income and the related taxes theron. The federal NOL's begin to expire in 2019 and the state NOL's begin to expire in 2018. The federal and state R&D credits both begin to expire in 2018. A full valuation allowance has been provided against our 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.

Off-Balance Sheet Arrangements, Contractual Obligations, and Contingent Liabilities and Commitments

As of December 31, 2017, we did not have any off-balance sheet financing arrangements.

The following table summarizes our principal contractual obligations as of December 31, 2017 and the effects such obligations are expected to have on our liquidity and cash flows in future periods.

Contractual Obligations	Total		Payments due in
			Less than 1 year		1 – 3 years		3 – 5 years		More than 5 years
Operating lease obligations	$	2,167,173	$	573,421	$	1,024,811	$	568,941	$	—
Purchase order obligations	4,218,229		4,218,229		—		—		—
Total contractual obligations	$	6,385,402	$	4,791,650	$	1,024,811	$	568,941	$	—

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

35

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 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. Revenues associated with our 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 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 recognize 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 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. The realizable value of inventories is based upon the types and levels of inventories held, forecasted demand, pricing, competition, and changes in technology. Our consumables 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 February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 requires that lessees will need to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. The provisions of this guidance are effective for annual periods beginning after December 31, 2018, and for interim periods therein. The Company is in the process of evaluating the new standard and assessing the impact, if any, ASU 2016-02 will have on the Company’s financial statements.

In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued Accounting Standards Update (“ASU”) No. 2014-9, Revenue from Contracts with Customers (“ASU 2014-9”), a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance. The objective of ASU 2014-9 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. While the Company is still in the process of completing its evaluation of the standard, it believes the most significant impact will be related to the timing of recognition of sales to certain consumer retail distributors. Upon adoption of ASU 2014-09, the Company will no longer be permitted to defer revenue under the sell-through model, but rather, will be required to estimate the effects of returns and allowances provided to distributors and record revenue at the time of sale to the distributor resulting in earlier recognition of revenues. The Company expects to adopt ASU 2014-09, using the full retrospective method, upon its effective date of January

36

1, 2018. The Company anticipates the impact of adoption will be a credit to accumulated deficit of approximately $0.3 million as of January 1, 2018.

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.

ITEM 8. Financial Statements and Supplementary Data

The information required by this item may be found on pages F-1 through F-22 of this Annual Report on Form 10-K.

ITEM 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

ITEM 9A. Controls and Procedures

(a) Evaluation of disclosure controls and procedures.

Our principal executive officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this Form 10-K, have concluded that, based on such evaluation, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

(b) Management’s Report on Internal Control Over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2017 based on the criteria in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on our evaluation under the framework in Internal Control — Integrated Framework (2013) issued by the COSO, our management concluded that our internal control over financial reporting was effective as of December 31, 2017.

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

(c) Changes in internal control over financial reporting.

37

There have been no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B. Other Information

The Company has received a Civil Investigative Demand (“CID”) from the United States Federal Trade Commission (“FTC”). The CID requests 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 is in the process of producing 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.

The Company intends to repurchase, from time to time, warrants to purchase its common stock that are traded on Nasdaq under the symbol NUROW. The Company may expend up to $25,000 in making these purchases on Nasdaq from time to time.

On February 5, 2018, we entered into Amendment No. 10 to our Shareholder Rights Agreement (“Amendment No. 10”) with American Stock Transfer & Trust Company, LLC dated as of March 7, 2007, as amended. Amendment No. 10 extends the term of the Shareholder Rights Agreement by an additional year. The foregoing description of Amendment No. 10 is subject to, and is qualified in its entirety by reference to, the full text of Amendment No. 10, a copy of which is set forth as Exhibit 4.2.10 to this Annual Report on Form 10-K and is incorporated herein by reference

BOARD MATTERS AND CORPORATE GOVERNANCE

Board of Directors

Our amended and restated certificate of incorporation, as amended, provides for a classified board of directors consisting of three staggered classes of directors (Class I, Class II and Class III). The members of each class of our Board of Directors serve for staggered three-year terms, with the terms of our Class II, Class III and Class I directors expiring upon the election and qualification of directors at the annual meetings of stockholders to be held in 2018, 2019, and 2020, respectively. Currently:

• our Class I director is Timothy R. Surgenor;

• our Class II directors are Shai N. Gozani, M.D., Ph.D. and David Van Avermaete; and

• our Class III directors are David E. Goodman, M.D. and Nancy E. Katz.

Our Board of Directors has determined that Dr. Goodman, Mr. Surgenor, Ms. Katz, and Mr. Van Avermaete are independent directors for purposes of the corporate governance rules contained in the Nasdaq Marketplace Rules, or the Nasdaq rules.

Our Board of Directors has an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee.

The Audit Committee currently consists of Mr. Surgenor, Chairman, Dr. Goodman, and Ms. Katz. The Audit Committee operates pursuant to a charter that was approved by our Board of Directors, a copy of which is available on our website at http://www.neurometrix.com under the heading “Investor Relations” and subheading “Corporate Governance”. The purposes of the Audit Committee are to, among other functions, assist the Board of Directors in overseeing the operation of a comprehensive system of internal controls covering the integrity of our financial statements and reports, compliance with laws, regulations and corporate policies, and the qualifications, performance and independence of our registered public accounting firm. Mr. Surgenor, Dr. Goodman, and Ms. Katz are all “independent” as that term is defined in the rules of the SEC and the applicable Nasdaq rules relating to audit committee members. Our Board of Directors has determined that Mr. Surgenor qualifies as an “audit committee financial expert” as such term is defined in the rules of the SEC. The Audit Committee held six meetings during 2017.

Such Reporting Persons are required by regulations of the SEC to furnish us with copies of all such filings. Our records reflect that all reports which were required to be filed pursuant to Section 16(a) of the Exchange Act were filed on a timely basis. We received a written statement from our directors, officers, and 10% stockholders or know from other means that any required Forms 5 were filed or that no Forms 5 were required to be filed.

ITEM 11. Executive Compensation

Directors’ Compensation

As of December 31, 2017, the non-employee members of our Board of Directors were entitled to receive annual cash compensation in the amount of $15,000 for service as a member of our Board of Directors, which is paid following each annual meeting of our stockholders. In addition, these non-employee directors were entitled to receive $2,000 for each board or committee meeting that they attend, provided that they are not entitled to additional compensation for attending committee meetings that occur on the same day as a board meeting which they attend. This cash compensation is in addition to any stock options or other equity compensation that we determine to grant to our directors. Dr. Gozani, the only member of our Board of Directors who is also an employee, is not separately compensated for his service on our Board of Directors.

In addition to the compensation described above, we reimburse all non-employee directors for their reasonable out-of-pocket expenses incurred in attending meetings of our Board of Directors or any committees thereof.

The following table shows compensation information with respect to services rendered to us in all capacities during the fiscal year ended December 31, 2017 for each non-employee member of the Board of Directors.

(1) These amounts include the aggregate grant date fair value for option awards granted during fiscal years 2017 and 2016 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, 2017, base salaries for our executive officers are Dr. Gozani — $415,000, Mr. Higgins — $325,000, and Mr. McGillin — $325,000.

Bonus Payments

Each executive officer has an annual bonus target which is expressed as a percentage of base salary. For 2017, 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 the 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 2017 encompassed targets for new equity funding, strategic collaboration, sales revenue, and product development.

Long-Term Incentive Compensation

43

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. During 2017 there were no equity grants to the executive officers. The Compensation Committee awarded in August 2016 the following equity grants comprised of stock options, to our named executive officers under our 2004 Stock Plan in the following amounts: Dr. Gozani — 25,000 options; Mr. Higgins — 12,500 options; and Mr. McGillin — 12,500 options.

Stock options referred to above have a term of ten years and vest over four years with 25% of the total award vesting after one year and the remainder vesting in equal quarterly installments thereafter. 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 reduced 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 equity 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.

Outstanding Equity Awards at Fiscal Year-End

The table below sets forth information with respect to our named executive officers concerning the outstanding equity awards as of December 31, 2017.

• each of our named executive officers;

• all of our directors and executive officers as a group; and

Private Offering of Convertible Preferred Stock; exchange of Warrants for Convertible Preferred Stock;

In the third quarter of 2017, we completed a private equity offering, or the Q3 2017 Offering, with entities affiliated with Sabby Management, LLC and its affiliates, or Sabby, a principal stockholder, providing for the issuance of (i) 7,000 shares of Series F convertible preferred stock at a price of $1,000 per share and (ii) 3,621 shares of Series F Preferred Stock in exchange for the repurchase and retirement of 4,184,483 warrants to purchase common stock valued by an independent party at $3,622,219. The Q3 2017 Offering also reset the conversion price of 14,052.93 shares of Series D convertible preferred stock and 7,000 shares of Series E convertible preferred stock that were held by Sabby to $2.63 per share. The Q3 2017 Offering resulted in gross proceeds of $7.0 million, and after deducting fees and expenses, net proceeds were $6.6 million. Each share of Series F convertible preferred stock has a stated value of $1,000 and is convertible, at any time at the option of the holder thereof, into a number of shares of our common stock determined by dividing the stated value by the initial conversion price of $2.63, subject to a 4.99% beneficial ownership limitation.

In the first quarter of 2017, we completed a private equity offering, or the Q1 2017 Offering, with Sabby, providing for the issuance of (i) 7,000 shares of Series E convertible preferred stock at a price of $1,000 per share, and (ii) warrants to purchase up to 1,250,000 shares of common stock, par value $0.0001 per share (the “Common Stock”), at an exercise price of $5.60 per share.

The Q1 2017 Offering resulted in gross proceeds of $7.0 million, and after deducting fees and expenses, net proceeds were $6.3 million. Each share of Series E convertible preferred stock has a stated value of $1,000 and is convertible, at any time at the option of the holder thereof, into a number of shares of our common stock determined by dividing the stated value by the adjusted conversion price of $2.63, subject to a 4.99% beneficial ownership limitation.

Private Offering of Convertible Preferred Stock and Warrants; Repurchase of Series C Convertible Preferred Stock

In June 2016, we completed a private equity offering, or the 2016 June Offering, with entities affiliated with Sabby, a principal stockholder, providing for the issuance of (i) 21,300 shares of Series D convertible preferred stock at a price of $1,000 per share, and (ii) warrants to purchase up to 1,475,069 shares of our common stock at an exercise price of $13.52 per share.

The June 2016 Offering resulted in proceeds of $7.5 million. After fees and expenses, net proceeds of the June 2016 Offering were $6.7 million. Each share of Series D convertible preferred stock has a stated value of $1,000 and is convertible, at any time at the option of the holder thereof, into a number of shares of our common stock determined by dividing the stated value by the adjusted conversion price of $2.63, subject to a 4.99% beneficial ownership limitation.

Report of Independent Registered Public Accounting Firm

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

Opinion on the Financial Statements

We have audited the accompanying balance sheet of NeuroMetrix, Inc. (the Company) as of December 31, 2017, and the related statements of operations, changes in stockholders’ equity, and cash flows for the year 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 the Company as of December 31, 2017, and the results of its operations and its cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

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, negative cash flows from operating activities and has an accumulated deficit that raise substantial doubt about its ability to continue as a going concern. Management'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

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

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

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

We have served as the Company’s auditor since 2017.

We conducted our audit of these financial 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 audit provides a reasonable basis for our opinion.

The accompanying financial statements have been prepared assuming 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 that raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Notes to Financial Statements

1. Description of Business and Basis of Presentation

NeuroMetrix, or the Company, is a commercial stage, innovation driven healthcare company combining bioelectrical and digital medicine to address chronic health conditions including chronic pain, sleep disorders, and diabetes. The Company’s lead product is Quell, an over-the-counter wearable therapeutic device for chronic pain. Quell is integrated into a digital health platform that helps patients optimize their therapy and decrease the impact of chronic pain on their quality of life. The Company also markets DPNCheck®, a rapid point-of-care test for diabetic neuropathy, which is the most common long-term complication of Type 2 diabetes. The Company maintains an active research effort. The company is located in Waltham, Massachusetts and was founded as a spinoff from the Harvard-MIT Division of Health Sciences and Technology in 1996.

During 2017 the Company completed two equity offerings, detailed in Note 12 to the financial statements, which resulted in gross proceeds of $14.0 million and realized net proceeds of approximately $12.9 million after deducting fees and expenses.

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, 2017, the Company had an accumulated deficit of $191.3 million. The Company held cash and cash equivalents of $4.0 million as of December 31, 2017. The Company believes that these resources, the $5.0 million received in January 2018 under the GSK Collaboration, as well as certain of the $21.5 million in contingent payments under development and commercialization milestones (Note 15), and the cash to be generated from expected product sales will be sufficient to meet its projected operating requirements into the fourth quarter of 2018. 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; and (f) other items affecting the Company’s forecasted level of expenditures and use of cash resources. Accordingly, the Company may need to raise additional funds to support its operating and capital needs in the fourth quarter of 2018. 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. The Company intends 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.

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.

Notes to Financial Statements

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.

At December 31, 2017 and 2016, two customers accounted for 66% and 41% of accounts receivable, respectively. For the years ended December 31, 2017 and 2016, customers accounting for more than 10% of revenue were 19% and zero of revenues, respectively.

The Company relies on in-house assembly and four 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 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.

Fair Value

The carrying amounts of the Company’s accounts receivable, accounts payable, and accrued expenses approximate their fair value at December 31, 2017 and 2016 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. Revenues associated with the Company’s medical devices and consumables are generally recognized upon shipment, assuming all other revenue recognition criteria have been met. Revenue associated with shipments made to distributors who have the right to return any unsold product is recognized once the product is sold by the distributor to the end customer (i.e. under a sell-through model), assuming all other revenue recognition criteria have been met. Cash received prior to all the conditions for revenue recognition being met is recorded as deferred revenue.

As of December 31, 2017, the total value of shipments made to sell-through distributors but not yet sold through to end customers totaled $3,010,734. Of this total, $2,190,703 was recorded as a reduction to accounts receivable and $820,031 was recorded in deferred revenue, as cash had been received. As of December 31, 2016, the total value of shipments that had been made to sell-through distributors but have not yet been sold through to end customers totaled $1,247,545. Of this total, $619,309 was recorded as a reduction to accounts receivable and $628,236 was recorded in deferred revenue, as cash had been received. Related costs of goods sold of $2,106,988 and $910,595 have been deferred and recorded in prepaid expenses and other current assets as of December 31, 2017 and 2016, respectively.

2. Summary of Significant Accounting Policies - (continued)

Revenue recognition involves judgments, including assessments of expected returns from customers who have the right to return product for any reason under 30-day or 60-day rights of return. Where the Company can reasonably estimate future returns, it recognizes revenues and records as a reduction of revenue a provision for estimated returns. The Company analyzes various factors, including its historical product returns in arriving at this judgment. Changes in judgments or estimates could materially impact the timing and amount of revenues and costs recognized. The provision for expected returns recorded as accrued expense was $666,375 and $488,200 as of December 31, 2017 and 2016, respectively.

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 our 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 our customers.

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.

Notes to Financial Statements

2. Summary of Significant Accounting Policies - (continued)

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 $127,361 and $45,879 at December 31, 2017 and 2016, 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).

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 loss per common share. Diluted net 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 such 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 loss per share amounts, shares underlying the following potentially dilutive weighted average number of common stock equivalents were excluded from the calculation of diluted net loss per common share because their effect was anti-dilutive for each of the periods presented:

	Years Ended December 31,

Warrants	2,742,266	2,848,791

Advertising and Promotional Costs

Advertising and promotional costs are expensed as incurred. Advertising and promotion expense were approximately $6,851,000 and $6,311,000, in 2017 and 2016, respectively.

Accumulated Other Comprehensive Items

For 2017 and 2016, the Company had no components of other comprehensive income or loss other than net loss.

Segments

The Company operates in one segment for the sale of medical equipment and consumables. Substantially all of the Company’s assets, revenues, and expenses for 2017 and 2016, were located at or derived from operations in the United States. Revenues from sales outside the United States accounted for approximately 7% and 12% of total revenues in 2017 and 2016, respectively.

Risks and Uncertainties

The Company is subject to risks common to companies in the medical device industry, including, but not limited to, development by the Company or its competitors of new technological innovations, dependence on key personnel, customers’ reimbursement from third-party payers, protection of proprietary technology, and compliance with regulations of the FDA and other governmental agencies.

Recently Issued or Adopted Accounting Pronouncements

In February 2016, the FASB issued Accounting Standards Update No. 2016-2, Leases (Topic 842) (“ASU 2016-2”). ASU 2016-2 requires that lessees will need to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. The provisions of this guidance are effective for annual periods beginning after December 31, 2018, and for interim periods therein. The Company is in the process of evaluating the new standard and assessing the impact, if any, ASU 2016-2 will have on the Company’s Financial Statements.

In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued Accounting Standards Update (“ASU”) No. 2014-9, Revenue from Contracts with Customers (“ASU 2014-9”), a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance. The objective of ASU 2014-9 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. While the Company is still in the process of completing its evaluation of the standard, it believes the most significant impact will be related to the timing of recognition of sales to certain consumer retail distributors. Upon adoption of ASU 2014-09, the Company will no longer be permitted to defer revenue under the sell-through model, but rather, will be required to estimate the effects of returns and allowances provided to distributors and record revenue at the time of sale to the distributor resulting in earlier recognition of revenues. The Company expects to adopt ASU 2014-09, using the full retrospective method, upon its effective date of January 1, 2018. The Company anticipates the impact of adoption will be a credit to accumulated deficit of approximately $0.3 million as of January 1, 2018.

3. Stock-Based Compensation

During 2004, the Company adopted the 2004 Stock Option and Incentive Plan, as amended and restated most recently in 2016. At the Annual Meeting of Stockholders held on May 2, 2017, the stockholders of the Company approved the Company’s Ninth Amended and Restated 2004 Stock Option and Incentive Plan (the “2004 Stock Plan”), which, among other things, increased the number of shares of the Company’s common stock authorized for issuance thereunder by 600,000 shares. The 2004 Stock Plan, among other things, provides for granting of incentive and nonqualified stock option and stock bonus awards to officers, employees and outside consultants. Outstanding options under the 2004 Stock Plan generally vest over three or four years and terminate 10 years after the grant date, or earlier if the option holder is no longer an executive officer, employee,

consultant, advisor or director, as applicable, of the Company. As of December 31, 2017, 728,946 shares of common stock were authorized for issuance under the 2004 Stock Plan, of which 30,162 shares had been issued, 80,537 shares were subject to outstanding options at a weighted average exercise price of $19.32 per share and 618,247 shares were available for future grant.

During May 2009, the Company adopted the 2009 Non-Qualified Inducement Stock Plan (the “2009 Inducement Plan”). The 2009 Inducement Plan is intended to encourage and enable employees, including prospective employees, of the Company upon whose judgment, initiative, and efforts the Company largely depends for the successful conduct of its business to acquire a proprietary interest in the Company. The 2009 Inducement Plan, among other things, provides for the granting of awards, including non-qualified stock options, restricted stock, and unrestricted stock. As of December 31, 2017, 12,500 shares of common stock were authorized for issuance and were available for future grant under the 2009 Inducement Plan.

The exercise price of stock options awarded under the 2004 Stock Plan and the 2009 Inducement Plan may not be less than the fair value of the common stock on the date of the option grant. For holders of more than 10% of the Company’s total combined voting power of all classes of stock, incentive stock options may not be granted at less than 110% of the fair value of the Company’s common stock at the date of grant and for a term not to exceed five years.

In June 2004, the Company adopted the 2004 Employee Stock Purchase Plan (the “2004 ESPP”). All of the Company’s employees who had been employed by the Company for at least 60 days and whose customary employment is for more than 20 hours per week and for more than five months in any calendar year were eligible to participate and any employee who owned 5% or more of the voting power or value of the Company’s stock was not eligible to participate. The 2004 ESPP authorized the issuance of up to a total of 326 shares of the Company’s common stock to participating employees.

In May 2010, the Company adopted the 2010 Employee Stock Purchase Plan (the “2010 ESPP”). The 2010 ESPP initially authorized the issuance of up to a total of 217 shares, of the Company’s common stock to participating employees plus an annual increase on the first day of each of the Company’s fiscal years beginning in 2011, equal to the lesser of (i) 521 shares, (ii) 1 percent of the shares of common stock outstanding on the last day of the immediately preceding fiscal year, or (iii) such lesser number of shares as is determined by the Board. All of the Company’s full-time employees and certain part-time employees are eligible to participate in the Amended and Restated 2010 ESPP. For part-time employees to be eligible, they must have customary employment of more than five months in any calendar year and more than 20 hours per week. Employees who, after exercising their rights to purchase shares under the Amended and Restated 2010 ESPP, would own shares representing 5% or more of the voting power of the Company’s common stock, are ineligible to participate.

Under the Amended and Restated 2010 ESPP, participating employees can authorize the Company to withhold up to 10% of their earnings during consecutive six-month payment periods for the purchase of the shares. At the conclusion of each period, participating employees can purchase shares at 85% of the lower of their fair value at the beginning or end of the period. The Amended and Restated 2010 ESPP is regarded as a compensatory plan. For the years ended December 31, 2017 and 2016 the Company issued 11,583 and 4,375 shares of its common stock, respectively, under the Amended and Restated 2010 ESPP. As of December 31, 2017, there were 58 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, 2017 and 2016 is calculated using the following assumptions:

Expected dividend yield	—		—
Expected option term	5 years		5 years
Volatility	70.0	%	70.0	%

The risk-free interest rate assumption is based on the United States Treasury’s constant maturity rate for a 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 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.

A summary of option activity for the year ended December 31, 2017 is presented below:

	Number of Options		Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value
Outstanding at December 31, 2016	97,891		$	37.95
Granted	6,488		2.37

Exercisable at December 31, 2017	25,388		37.26		8.3	—

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, 2017, 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, 2017.

The weighted average per share grant-date fair values of options granted during 2017 and 2016 was $2.37 and $6.80, respectively.

The aggregate intrinsic value of options issued or exercised during 2017 and 2016 was $0.

Total unrecognized stock-based compensation costs related to non-vested stock options was $335,405, which related to 80,537 shares with a per share weighted fair value of $19.32 as of December 31, 2017. This unrecognized cost is expected to be recognized over a weighted average period of approximately 2.6 years.

Cash received from option exercises and purchases under the 2004 ESPP and the 2010 ESPP for 2017 and 2016, was $20,768 and $28,538, respectively. The Company issues new shares upon option exercises, purchases under the Company’s ESPPs, and vesting of restricted stock.

The Company recorded stock-based compensation expense of $209,691 and $225,408 for 2017 and 2016, respectively.

At December 31, 2017, the Company has federal and state net operating loss carryforwards (“NOL”) of $145.2 million and $51.6 million, respectively, as well as federal and state tax credits of $1.5 million and $1.1 million, respectively, which may be available to reduce future taxable income and the related taxes thereon. This amount includes tax benefits of $2.6 million and $71,238 attributable to NOL and tax credit carryforwards, respectively, that result from the exercise of employee stock options. The tax benefit of these items will be recorded as a credit to additional paid-in capital upon realization of the deferred tax asset or reduction in income taxes payable. The federal NOLs begin to expire in 2019 and the state NOLs begin to expire in 2018. The federal and state research and development credits both begin to expire in 2018.

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 $35.3 million and $49.3 million has been established at December 31, 2017 and 2016, respectively. In 2017, the valuation allowance decreased primarily due to the impact of the change in statutory rates on the Company’s net operating losses. 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, 2017 or 2016. 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, 2014 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.

8. Commitments and Contingencies

Operating Leases

In August 2014, the Company entered into a 5-year operating lease agreement with one5-year extension option for manufacturing and order fulfillment facilities in Woburn, Massachusetts (the “Woburn Lease”). The Woburn Lease commenced December 15, 2014 and has a monthly base rent of $7,815. In September 2014, the Company entered into a 7-year operating lease agreement with one5-year extension option for its corporate office and product development activities in Waltham, Massachusetts (the “Waltham Lease”). The term of the Waltham Lease commenced on February 20, 2015 and includes fixed payment obligations that escalate over the initial lease term. Average monthly base rent under the 7-year lease is approximately $37,788. These payment obligations will be accrued and recognized over the term of occupancy such that rent expense is recognized on a straight-line basis. 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.

Future minimum lease payments under non-cancellable operating leases as of December 31, 2017 are as follows:

2018	573,421
2019	549,403
2020	475,408
2021	487,379
2022	81,562
Total minimum lease payments	$	2,167,173

Total recorded rent expense was $670,860 and $581,928, for 2017 and 2016, respectively. The Company records rent expense on its facility lease on a straight-line basis over the lease term.

Other Commitments

At December 31, 2017, other commitments, comprised of purchase orders, totaled approximately $4,218,229.

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

Notes to Financial Statements

9. Fair Value Measurements - (continued)

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.

Due to the lack of market quotes relating to our common stock warrants, the fair value of the common stock warrants was determined at December 31, 2016 using the Black-Scholes model, which is based on Level 3 inputs. As of December 31, 2016, inputs used in the Black-Scholes model are presented below. The assumptions used may change as the underlying sources of

10. Retirement Plan

The Company has established a 401(k) defined contribution savings plan for its employees who meet certain service period and age requirements. Contributions are permitted up to the maximum allowed under the Internal Revenue Code of each covered employee’s salary. The savings plan permits the Company to contribute at its discretion. In 2017 and 2016 the Company made no contributions to the plan.

11. Credit Facility

The Company is party to a Loan and Security Agreement, or the Credit Facility, with a bank. As of December 31, 2017, the Credit Facility permitted the Company to borrow up to $2.5 million on a revolving basis. The Credit Facility was subsequently amended, most recently on January 17, 2018 and extended until January 15, 2019. Amounts borrowed under the Credit Facility will bear interest equal to the prime rate plus 0.5%. Any borrowings under the Credit Facility will be collateralized by the Company’s cash, accounts receivable, inventory, and equipment. The Credit Facility also includes traditional lending and reporting covenants. These include certain financial covenants applicable to liquidity that are to be maintained by the Company. As of December 31, 2017, the Company was in compliance with these covenants and had not borrowed any funds under the Credit Facility. However, $0.2 million of the amount under the Credit Facility is restricted to support letters of credit issued in favor of our facilities landlords. Consequently, the amount available for borrowing under the Credit Facility as of December 31, 2017 was approximately $2.3 million.

12. Stockholder's Equity - (continued)

2017 activity

In 2017, the Company entered into agreements with respect to a private equity offering (the “Q3 2017 Offering”) with an institutional investor and its affiliates (collectively the “Investor”). In the Q3 2017 Offering, the Company issued 7,000 shares of Series F convertible preferred stock (the “Series F Preferred Stock”) at a price of $1,000 per share. The Q3 2017 Offering also reset the conversion price of 14,052.93 shares of Series D convertible preferred stock and 7,000 shares of Series E convertible preferred stock that were held by the Investor to $2.63 per share. The Q3 2017 Offering resulted in gross proceeds of $7.0 million, and after deducting fees and expenses, net proceeds were $6.6 million. In the third quarter of 2017, the Company also entered into an exchange agreement pursuant to which it issued the Investor 3,621 shares of Series F Preferred Stock in exchange for the repurchase and retirement of 4,184,483 warrants to purchase common stock valued by an independent party at $3,622,219.

Also in 2017, the Company completed a private equity offering (the “Q1 2017 Offering”) with the Investor and issued (i) 7,000 shares of Series E convertible preferred stock (the “Series E Preferred Stock”) at a price of $1,000 per share, and (ii) warrants to purchase up to 1,250,000 shares of common stock, par value $0.0001 per share (the “Common Stock”), at an exercise price of $5.60 per share. As a part of this offering, the Company reset (i) the conversion price of 19,458.90 shares of Series D convertible preferred stock that were held by the Investor to $5.60 per share, and (ii) the exercise price of warrants to purchase up to 2,934,484 shares of Common Stock that were held by the Investor to $5.60 per share. The Q1 2017 Offering resulted in gross proceeds of 7.0 million, and after deducting fees and expenses, net proceeds were $6.3 million.

Each share of Series D Preferred Stock, Series E Preferred Stock, and Series F Preferred Stock (collectively the "Preferred Stock") have a stated value of $1,000 and is 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 $2.63, which is subject to adjustment as provided in the Certificate of Designation for the Preferred Stock. The Preferred Stock has no dividend rights, liquidation preference or other preferences over Common Stock and has no voting rights except as provided in the Certificate of Designation for the Preferred Stock and as required by law.

The Q3 2017 Offering and the Q1 2017 Offering were accounted for as extinguishments of the Investor’s equity holdings in recognition of the revisions of certain preexisting equity instruments and the significant transfer of value in excess of the funding received by the Company. Under the extinguishment model, a deemed dividend was recognized within additional paid in capital which represented the fair value of issued Preferred Stock plus the incremental fair value of repricing the Preferred Stock held by the Investor, less the fair value of the consideration transferred, less the carrying value of the outstanding Preferred Stock, and warrants to purchase Common Stock. The amount of the deemed dividend totaled $2.8 million and $4.0 million for the Q3 2017 Offering and the Q1 2017 Offering, respectively.

The Company determined that equity classification was appropriate for the warrants issued in the Q1 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 five year warrants was estimated to be $3.5 million on the offering date using a Black-Scholes model with the following assumptions: stock price of $4.96, exercise price of $5.60, expected volatility of 70.2%, risk free interest rate of 2.04%, expected term of five years, and no dividends.

During 2017, 3,149.72 shares of the Series D Preferred Stock were converted into a total of 859,077 shares of common stock. As of December 31, 2017, 14,052.93 shares of Series D Preferred Stock remained outstanding. During 2017, 2,693.95 shares of the Series F Preferred Stock were converted into a total of 974,163 shares of common stock. As of December 31, 2017, 7,927.05 shares of Series F Preferred Stock remained outstanding.

As a part of this offering, the Company redeemed 13,800 shares of Series C convertible preferred stock (the “Series C Preferred Stock”) issued in the December 2015 Offering that were held by the Investor. Accordingly, the June 2016 Offering resulted in gross proceeds of $7.5 million, and after deducting fees and expenses, net proceeds were $6.7 million.

Each share of Series D Preferred Stock had a stated value of $1,000 and is 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 $14.44, which is subject to adjustment as provided in the Certificate of Designation for the Series D Preferred Stock.

The June 2016 Offering was accounted for as a modification of the Investor’s Series C Preferred Stock. Under the modification model, a deemed dividend was recognized within retained earnings which represented the fair value of consideration transferred plus the fair value of repurchased Series C Preferred Stock, less the fair value of the newly issued Series D Preferred Stock and warrants. The amount of the deemed dividend totaled $19.8 million.
