ITEM 1. BUSINESS

Our Business — An Overview

We are a medical device company focused on the diagnosis and treatment of the neurological complications of diabetes. People with diabetes do not effectively regulate their blood glucose, or sugar, levels leading to chronically high levels of glucose in the blood, called hyperglycemia, and occasionally bouts of low glucose in the blood, called hypoglycemia. The primary reason that glucose levels are not effectively regulated in people with diabetes is that those with the disease do not produce insulin (Type I diabetes) or are resistant to the normal physiological action of insulin (Type II diabetes). Many Type II diabetics eventually require insulin because production of the hormone by their pancreas decreases with time. Type I diabetes usually affects children and teenagers whereas Type II diabetes has typically been a disease of adults over the age of 50. However, over the past decade, Type II diabetes is occurring in younger adults, which can probably be attributed to higher levels of obesity in this age group.

Diabetes is a worldwide epidemic. Recent studies estimate the worldwide prevalence of diabetes to be over 350 million people, of which approximately 90% are of the Type II variety. Within the United States, there are over 25 million people with diabetes and another 80 million people with pre-diabetes, which represents a constellation of conditions such as obesity and high triglyceride levels that are likely to progress to diabetes. In the United States, the annual cost of treating diabetes is over $100 billion. Although there are dangerous acute manifestations of diabetes, the primary burden of the disease is in the long term

TABLE OF CONTENTS

complications of chronic hyperglycemia. These complications include among other things cardiovascular disease, nerve disease and resulting pathological conditions such as foot ulcers and amputation, eye disease leading to blindness, and kidney failure.

The most common long-term complication of diabetes, which affects over 50% of the diabetic population, is nerve disease or diabetic neuropathy. There are different forms of diabetic neuropathy; the most common are diabetic peripheral neuropathy, or DPN, carpal tunnel syndrome, or CTS, and autonomic neuropathy. DPN is a systemic nerve disease that is worse in the feet and lower legs. It may lead to loss of sensation in the feet, severe pain in the feet and legs, and increased risk of falling. DPN is the primary trigger for diabetic foot ulcers which may progress to the point where amputation is required. People with diabetes have a 15% to 25% lifetime risk of developing a foot ulcer and 15% of foot ulcers lead to amputation. Foot ulcers are among the most expensive complications of diabetes, with a typical cost of $5,000 to $50,000 per episode. CTS is caused by focal damage to the median nerve as it passes from the forearm into the hand, through the wrist. When the median nerve is compressed it can lead to symptoms in the hand including pain, numbness, and loss of strength. Autonomic neuropathy is a systemic disease of the autonomic nerves, which regulate the heart, digestion, sexual function, and other essential bodily functions. Damage to these nerves leads to a host of clinical complications that include an increased risk of sudden death, elevated risk of stroke, digestion difficulties and impotence.

Most people with diabetes receive health care attention in primary care settings where physicians have limited access to sophisticated diagnostic tools to detect diabetic neuropathy early and monitor its progress and response to treatment. As a result, they rely primarily on clinical examination of patients which, although it is an important part of the evaluation of a patient with diabetes, has limited sensitivity and specificity and can usually only detect later stage disease where treatment options and efficacy are compromised.

Early detection of DPN is particularly important because there are no treatment options once the nerves have degenerated. At the present time, the most widely used and recommended diagnostic method for DPN is the 5.07/10-g monofilament test. This test assesses the patient’s ability to detect focal pressure application in the foot. The inability to detect a monofilament indicates that the patient lacks adequate sensation to protect their feet from mechanical insults that can lead to foot ulcers; a condition known as loss of protection sensation, or LOPS. Although the monofilament is an important clinical test, it is insensitive to early DPN where interventions may slow or even halt further nerve damage. Nerve conduction studies, or NCS, are objective electrical tests of nerve function. They are considered the gold standard diagnostic method for DPN and can detect mild nerve damage before it is expressed as clinical symptoms. NCS have typically been provided by specialists using expensive equipment and therefore access has been limited, particularly for common conditions such as DPN.

Currently, there are limited treatment options for diabetic neuropathies. There are no approved disease modifying treatments for DPN, although a few pharmacological candidates are in clinical trials. Several large studies have shown that reducing hyperglycemia lowers the risk of developing DPN and decreases its severity. There is also observational data that suggests that reductions in triglyceride levels slows the progression of DPN. Several drugs, such as duloxetine and pregabalin, have been approved to treat the pain associated with DPN, which is referred to as painful diabetic neuropathy. Unfortunately, these drugs, which are also anti-depressants or anti-seizure medications, have systemic effects and are therefore-often associated with side effects. Like DPN, autonomic neuropathies are difficult to manage; however, early identification may allow physicians to lower cardiovascular risk. Mild to moderate CTS is effectively treated with conservative measures such as splinting and local steroid injections. More advanced CTS is usually managed surgically. In either case, it is essential to intervene before extensive nerve degeneration has occurred.

Our Strategy

We believe that there are large and important unmet needs in both the diagnosis and treatment of diabetic neuropathies. As a medical device company with both unique and substantial experience in devices to measure and alter peripheral nerve function, we believe we are in the unique position to address these unmet needs through the development of novel proprietary medical devices. Therefore, we are focused on developing and

TABLE OF CONTENTS

marketing medical devices for the diagnosis and treatment of diabetic neuropathies. We believe that we are the only medical device company with a strategic focus on the diabetic neuropathy market and our goal is to be the dominant player in this field.

Our key business strategies for 2013 by which we intend to advance our objectives in the diabetic neuropathy market include:

Driving Commercial Adoption of Our Proprietary Products for Diabetic Neuropathy in the United States.

Commercializing NC-stat DPNCheck in Select International Markets Using a Distribution
Network.  We are targeting select international markets where we believe that the combination of a high prevalence of diabetes plus support from the local payer system will support NC-stat DPNCheck and, eventually, SENSUS. This includes countries in Western Europe, including Germany and the Netherlands, where we have both CE marking for NC-stat DPNCheck and established distribution, as well as East Asia, including Japan and South Korea. While our resources committed to this effort are modest, we believe that this approach could contribute meaningful revenue in 2013 while positioning us for international growth in subsequent years.

Leveraging a More Efficient Operating Structure with Future Revenue Growth.  During the course of 2012 we modified our operating structure to focus more narrowly on the high-value opportunities for NC-stat DPNCheck and SENSUS that can be pursued via independent distributors and a small commercial operations team. This has reduced our operating expenses and, more significantly, improved our future flexibility to generate increased sales volume without the cost of adding sales representatives and field clinical support. Our

TABLE OF CONTENTS

operating expenses during 2012 totaled $14.0 million and we forecast 2013 operating expenses to be in the range of $11 to $12 million, a reduction of 14% to 21%. We believe we can maintain and leverage this approximate operating expense level over the next several years as our diabetes business grows.

Managing Our Legacy Neurodiagnostics Business to Optimize Cash Flow.  Our historical neurodiagnostics business generated $6.1 million in revenue during 2012 with gross margins exceeding 50%. There are few direct cash operating expenses of our neurodiagnostics business. Two years ago we shifted our strategic focus toward more attractive opportunities in diabetes care and we determined that we would manage this legacy neurodiagnostic business for its cash contribution rather than growth. This decision was primarily due to changes in the reimbursement environment which were challenging and presented few practical alternatives. We see the legacy business continuing to decline as we operate it for cash flow. See “— Legacy Neurodiagnostics Business.”

Our Business Model

We develop and market neurodiagnostic systems which typically consist of a medical device plus single patient-use biosensors or electrodes. Other accessories are also offered to our customers. Our goal for these systems is to build an installed base of active customer accounts and distributors that regularly reorder consumables 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 and, more recently, to the ADVANCE NCS/EMG System. The planning for our diabetes care pipeline, including NC-stat DPNCheck, SENSUS and other products in development, is based on the device plus consumables business model.

Marketed Products

NC-stat DPNCheck

NC-stat DPNCheck is a fast, accurate, and quantitative nerve conduction test that is used to evaluate systemic neuropathies such as 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.

NC-stat 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.

NC-stat DPNCheck is a modified version of our previously marketed NC-stat nerve testing device, and has the same clinical indications with respect to DPN. The modified device has the same functionality with respect to sural nerve testing as the original device; however, the cost of the electronic hand-held unit and the consumable biosensors has been reduced by approximately 50%. More than 1.7 million patient studies have been performed using our NC-stat technology and there have been approximately 6.3 million nerve tests, including nearly 700,000 sural 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.

SENSUS

The SENSUS pain therapy device is a transcutaneous electrical nerve stimulator, or TENS, designed for relief of chronic, intractable pain. We believe that SENSUS will be attractive to endocrinologists, podiatrists, and primary care physicians that are challenged with trying to manage pain in their patients with painful diabetic neuropathy, or PDN. We have used our unique expertise in peripheral nerve stimulation in the development of SENSUS which incorporates several proprietary features for ease of patient use and physician reporting. SENSUS is comprised of: (1) an electronic device with strap that is worn on the upper calf and (2) an electrode which attaches to the device. We provide prescribing physicians with PC-based software that links to the device via a USB connection thereby allowing them to download a record of the patient’s use of the device.

A recent evidence based review by the American Academy of Neurology determined that TENS was a useful modality for managing pain associated with diabetic peripheral neuropathy. Our assessment of currently

TABLE OF CONTENTS

available TENS devices indicated that the devices currently on the market do not meet the needs of patients with PDN because they are not optimized for PDN but are instead targeted at low back pain, sports medicine, and rehabilitation applications. Furthermore, they are difficult to administer and tend to be complicated for clinicians and patients.

Our SENSUS device and electrodes were cleared by the FDA for commercial distribution during 2012. When medically indicated and supported by proper documentation, TENS are generally reimbursed by Medicare and many commercial insurance companies under the DME benefit.

ADVANCE System

Our legacy neurodiagnostics business is based on the ADVANCE NCS/EMG System, or the ADVANCE System, which is a comprehensive platform for the performance of traditional nerve conduction studies and invasive electromyography procedures. The ADVANCE System is comprised of: (1) various types of electrodes and needles, (2) the ADVANCE device and related modules, 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.

Historically, the ADVANCE System has been 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 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.

Products in Development

SENTINEL^TM

SENTINEL is a device under development that is intended to provide sensory enhancement in the feet. It is targeted at patients who have lost sensory perception in the lower extremities, likely as a result of diabetes, and are at greater risk of falling and developing foot ulcers. The objective of this technology is to relay sensory input from the feet through the nervous system to the brain thereby improving balance and more immediate awareness of foot insults. SENTINEL is in the conceptual stages of product development and a target launch date has not been set.

Customers

Our customers include physicians, clinics, hospitals, managed care organizations, retail health businesses, independent distributors in the United States and abroad, and durable medical equipment suppliers. Our NC-stat DPNCheck device was launched in late 2011 and approximately 1,000 devices have been placed with customers through February 15, 2013. These customers include managed care organizations, retail health businesses, endocrinologists, podiatrists and primary care physicians. As of February 15, 2013, we had an installed base of approximately 1,800 active customers using our ADVANCE System. These customers include primary care, internal medicine, orthopedic and hand surgeons, pain medicine physicians, neurologists, physical medicine and rehabilitation, or PM&R, physicians, and neurosurgeons. Our SENSUS device was launched in January 2013 and is being sold to DME suppliers who, in turn, distribute the product along with consumables directly to patients. At December 31, 2012, one customer accounted for 11.5% of accounts receivable. For the years ended December 31, 2012, 2011, and 2010, no single customer accounted for more than 10% of revenue.

Geographic Information

Substantially all of our assets, revenues, and expenses for the years ended December 31, 2012, 2011, and 2010 were located at or derived from operations in the United States. In addition, we have had limited sales through distributors in the United Kingdom, the Netherlands, India, and various other countries. For each of the years ended December 31, 2012, 2011, and 2010, international revenues accounted for approximately 7%, 6%, and 2%, respectively, of our total revenues.

Sales, Marketing, and Distribution

NC-stat DPNCheck, our diagnostic test for DPN, was launched late in 2011 into the United States market for endocrinology and podiatry, followed by market evaluations and/or sales efforts in primary care, retail health, and managed care. While we believe that all of these segments hold potential, we have narrowed our focus to managed care, and specifically Medicare Advantage providers, which we believe represent the most attractive near-term opportunity. The Medicare Advantage market encompasses approximately 15 million covered lives or about 27% of the total Medicare population. We believe that this represents an attainable market in the range of $75 to $150 million. We have a four person senior level commercial operations team led by our Chief Operating Officer that is focused on developing the Medicare Advantage market.

TABLE OF CONTENTS

SENSUS, our therapeutic device for relief of chronic, intractable pain, was launched in January 2013. We believe this product will be attractive to endocrinologists, podiatrists, and primary care physicians that are challenged with trying to manage pain in their patients with diabetes. The prevalence of painful diabetic neuropathy is 16 – 26% of people with diabetes representing a 4 – 6 million patient group. The attainable market potential for SENSUS, we believe, could be 10% of this patient group representing annual revenue in the range of $150 to $200 million. We have seven regional DME distributors in place with 30 sales representatives as of February 15, 2013. Our goal in building national coverage is 100 sales representatives by mid-2013 and 250 sales representatives by the end of 2013. Further, during 2013 we have set a goal of 2,000 patients treated with SENSUS resulting in $1 million in product revenue.

Our installed base of ADVANCE accounts is supported by our customer service department which includes a director and three representatives. We are not actively pursuing new ADVANCE customers. Interest expressed in new ADVANCE systems by potential customers is handled by our customer service department and our marketing department. Internationally, ADVANCE sales and account support is handled by our network of independent distributors who are directed by our European Sales Manager.

Our marketing support for NC-stat DPNCheck and for ADVANCE is provided by our Senior Vice President of Commercial Operations and two marketing staff.

We invest significant effort in technical, clinical, and business practices training for our commercial operations team, marketing staff and independent sales representatives. We also require attendance at periodic sales and product training programs. Promotion and sales of medical devices are highly regulated not only by the FDA, but also by the U.S. Centers for Medicare and Medicaid Services, or CMS, and the Office of Inspector General, or OIG, and, outside the United States, by other international bodies, and are subject to federal and state fraud and abuse enforcement activities. See “— FDA and other Governmental Regulation” below.

Manufacturing and Supply

We perform final assembly and servicing of our new NC-stat DPNCheck and SENSUS devices at our corporate headquarters facility. We rely on an outside contractor for the manufacture and servicing of our ADVANCE device and also for the components that we use in the buildup for NC-stat DPNCheck and SENSUS. We rely on outside contractors for the manufacture of our consumable biosensor/electrodes. With the exception of the biosensors for use with our NC-stat DPNCheck devices, which we acquire from two manufacturers, we do not currently maintain alternative manufacturing sources for our NC-stat DPNCheck, SENSUS or ADVANCE devices, communication hubs, biosensors/electrodes, or any other finished goods products. 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, kitting, packaging, and labeling at our corporate headquarters facility. We believe these manufacturing relationships minimize our capital investment, provide us with manufacturing expertise, and help control costs.

Sunburst EMS, Inc., or Sunburst, has been manufacturing our NC-stat devices since November 2005. We entered into a supply agreement with Sunburst during 2006 for the manufacturing and supply of our neurodiagnostic devices. Sunburst manufactures the current generation of our ADVANCE device as well as the NC-stat DPNCheck and SENSUS subassemblies at a facility in Massachusetts.

Polymer Flexible Circuits, Inc., or Parlex, has been manufacturing our nerve specific electrodes since early 1999. In 2011 Parlex began manufacturing the NC-stat DPNCheck biosensors. In August 2006, we entered into a mutually exclusive manufacturing and supply agreement with Parlex pursuant to which Parlex will manufacture and supply to us, and we will purchase from Parlex, at agreed upon prices per unit, all of our requirements of nerve conduction testing electrodes for resale in the United States. Under the agreement, Parlex has agreed not to manufacture electrodes to be used to measure nerve conduction for any other company during the term of the agreement and, in some cases, for a period of one year thereafter. This agreement will continue indefinitely until terminated by either party upon not less than 18 months prior

written notice to the other party. Parlex manufactures our electrodes at a facility in Massachusetts and also has the ability to perform certain manufacturing steps for our electrodes at a second site located in the United Kingdom.

Katecho, Inc., or Katecho, a full service original equipment manufacturer (OEM) specializing in medical and cosmetic devices manufactures biosensors for use with our NC-stat DPNCheck devices in international markets and initiated manufacturing SENSUS electrodes during 2012 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 European agencies. Our ADVANCE System and NC-stat DPNCheck are cleared for marketing within the United States, Canada, and the European Union. In addition, our SENSUS Pain Management System is cleared for marketing in the United States. 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. Key members of our R&D management team have worked together for over a decade. This team includes the extensive involvement of our founder and Chief Executive Officer who holds both M.D. and Ph.D. degrees. The R&D group consists of 11 people, including two who hold M.D. degrees and three who hold Ph.D. degrees. The group has extensive experience in neurophysiology, biomedical instrumentation, signal processing, biomedical sensors, and information systems. The R&D group works closely with our marketing group and our customers to design new and modified products that are focused on improving clinical outcomes. Our clinical programs are led by our Chief Medical Officer who is a board-certified endocrinologist with extensive diabetes management experience.

Our research and development efforts are primarily focused in the following areas:

In addition to these core areas of research and development focus, we are also exploring additional clinical applications within the diagnosis and treatment of diabetic neuropathy for our core technology and expertise.

Research and development expenses were approximately $3.5 million, $3.9 million, and $5.9 million for the years ended December 31, 2012, 2011, and 2010, respectively.

TABLE OF CONTENTS

Clinical Programs

We maintain a clinical program under the direction of our Chief Medical Officer, who is a board certified endocrinologist with extensive experience in diabetes. Our clinical programs are 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.

Following is a list of external studies involving the use of our products which are currently underway.

Competition

Other than NC-stat DPNCheck, we believe that there is currently no 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 a large 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.

With respect to SENSUS, there are numerous manufactures of transcutaneous electrical nerve stimulation devices. We believe that the largest company is Empi, Inc. which is part of DJO Incorporated. We further believe that most of the current manufacturers are focused on low back pain, sports medicine, and rehabilitation rather than on painful diabetic neuropathy. As a result, we are not aware of any devices that are uniquely optimized for use in treating painful diabetic neuropathy. There are a few companies that claim that

TABLE OF CONTENTS

their devices have specific utility for painful diabetic neuropathy; however, we do not believe that these claims have been widely validated through adequate clinical studies.

There are several companies that sell neurodiagnostic devices. These companies include Cadwell Laboratories, Inc. and Natus Medical Incorporated. Natus Medical Incorporated has substantially greater financial resources than we do. Natus Medical Incorporated and Cadwell Laboratories, Inc. have established reputations as having effective worldwide distribution channels for medical instruments to neurologists and PM&R 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 NC-stat, SENSUS, ADVANCE, and NC-stat DPNCheck 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, 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, 2012, we had 38 issued U.S. patents, one issued foreign patent, and 17 pending patent applications, including nine U.S. applications, five international PCT applications, and three foreign national applications. We have filed a utility patent application for NC-stat DPNCheck and another utility patent application for SENSUS.

Our issued design patents begin to expire in 2015, and our issued utility patents begin to expire in 2017. In particular, seven of our issued U.S. utility patents covering various aspects of our current products will expire on the same date in 2017. Although the patent protection for material aspects of our products covered by the claims of the patents will be 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 marks NEUROMETRIX and NC-stat. We use a trademark for ADVANCE, NC-stat DPNCheck and SENSUS. We hold certain foreign trademark registrations for the marks NEUROMETRIX and NC-stat.

Third-Party Reimbursement

Procedures performed with our neurodiagnostic medical devices including ADVANCE and NC-stat DPNCheck may be paid for by third-party payers, including government health programs, such as Medicare, and private insurance and managed care organizations. The 2013 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 NC-stat DPNCheck device and the ADVANCE System.

We believe that physicians are generally receiving reimbursement under CPT 95905 from Medicare for nerve conduction studies performed 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 NC-stat 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 NC-stat DPNCheck is attractive to Medicare Advantage insurers and risk bearing provider organizations. We are focusing our sales effort for NC-stat DPNCheck on the Medicare Advantage managed care market segment.

We believe that the 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 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 the NC-stat DPNCheck and SENSUS devices and the ADVANCE System 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 Item 1A, “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, the adoption of our products 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:

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 Item 1A, “Risk Factors,” “We are subject to extensive regulation by the FDA which could restrict the sales and marketing of the NC-stat DPNCheck and SENSUS 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

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

TABLE OF CONTENTS

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:

TABLE OF CONTENTS

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 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 NC-stat DPNCheck.

As a transcutaneous electrical nerve stimulator, the SENSUS pain therapy device is a Class II medical device which received 510(k) clearance from the FDA in August 2012. In November 2012 the FDA provided 510(k) clearance for the disposable electrode used in conjunction with the SENSUS device. The intended use of the SENSUS pain management therapeutic system is the symptomatic relief and management of chronic intractable pain.

Manufacturing Facilities

Our facility, and the facility utilized by Sunburst, our contract device manufacturer, 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 manufacturer are in substantial compliance with the QSR. We expect that our facility 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

TABLE OF CONTENTS

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 lead 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 has been such that we have been unable to secure broad coverage among private payers, which is essential to the success of our ADVANCE System product. This experience was reflected in our revenues for the legacy Neurodiagnostics business, which peaked in 2006 at $55.3 million. We reported revenue of $6.1 million, $10.3 million, and $13.9 million in 2012, 2011, and 2010, respectively, for the legacy Neurodiagnostics business.

As we managed our general purpose neurodiagnostic business to improve reimbursement and minimize customer erosion, we increasingly became aware of the unmet medical need for improved diagnostic tools and therapies in the specific area of diabetic neuropathy, or nerve damage caused by diabetes. Diabetes care is one of the fasted growing sectors of health care as discussed above. We believe that our tools and therapies for addressing diabetic neuropathy represent a significant market opportunity. Consequently, in January 2011 we announced a shift to diabetes care as our primary business focus. We also restructured our neurodiagnostics business to consolidate functions and to eliminate our direct sales force. We emphasized our commitment to supporting our neurodiagnostic products and installed base of physician accounts. Our objective for our legacy neurodiagnostics business is to maintain a high standard of product support while managing the business to optimize cash flow.

Employees

As of December 31, 2012, we had a total of 39 employees, 38 of which were full-time employees. Of these employees, 11 were in research and development, 13 in sales and marketing, five in production/distribution, and nine in general and administrative services. One employee holds both M.D. and Ph.D. degrees, two additional employees hold M.D. degrees, and three additional employees hold Ph.D. degrees.

Our employees are not represented by a labor union and are not subject to a collective bargaining agreement. We have never experienced a work stoppage. We believe that we have good relations with our employees.

ITEM 1A. Risk Factors

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

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

We have incurred significant cumulative net losses since our inception. Our net losses for the years ended December 31, 2012, 2011, and 2010 were approximately $10.0 million, $10.0 million, and $16.9 million, respectively, reflecting a decline in revenues. At December 31, 2012, we had an accumulated deficit of approximately $138.6 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.

Two years ago, we shifted our business focus to diabetes care. We cannot assure you that we will be successful in this field or that our initial commercial products for diabetes care, NC-stat DPNCheck and SENSUS, or the products in our development pipeline, will be successful.

Our strategic focus is diabetes care. Our initial diabetes care product, NC-stat DPNCheck which was launched in late 2011, is a fast, accurate, and quantitative nerve conduction test for systemic neuropathies, such as DPN. In January 2013, we launched SENSUS, our pain management therapeutic device for relief of chronic, intractable pain. We also have other products in our development pipeline. Our future prospects are closely tied to our success with our NC-stat DPNCheck and SENSUS devices which, in turn, depends upon market acceptance and growth in future revenues. We cannot assure you that our diabetes care strategy, including the commercialization of our current products and other products in our development pipeline, will be successful. If our diabetes care 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:

If we are unable to expand exposure and penetrate the market for NC-stat DPNCheck and SENSUS, our ability to increase our revenues will be limited and our business prospects will be adversely affected.

We currently rely on sales of the products that comprise the ADVANCE System to generate a substantial portion of our revenues. Any factors that negatively impact our sales of these products could significantly reduce our ability to generate revenues.

We launched the ADVANCE System, our sophisticated nerve conduction testing system, in June 2008. For the year ended December 31, 2012, $6.1 million of our $7.6 million in total revenue was attributed to the ADVANCE System. We continue to derive a substantial portion of our revenues from sales of the products that comprise this system, particularly from electrodes. We expect that sales of ADVANCE System products will constitute more than half of our sales during 2013. Accordingly, our ability to generate revenues in the short-term is dependent on our ability to market and sell the products that comprise the ADVANCE System, particularly electrodes. Our sales of these products may be negatively impacted by many factors, including:

TABLE OF CONTENTS

If any of these events occurs, our ability to generate revenues from the ADVANCE System could be significantly reduced.

If health care providers are unable to obtain sufficient reimbursement or adjustment to capitated premium payments from third-party health care payers related to the use of our products, the adoption of our products and our future product sales will be materially adversely affected.

Widespread adoption of our 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 our 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, 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, cannot be predicted.

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

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

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

TABLE OF CONTENTS

revenue and future profitability. We have made modifications to our devices in the past and may make additional modifications in the future that we believe do not or will not require additional clearances or approvals. If the FDA disagrees, and requires new clearances or approvals for the modifications, we may be required to recall and to stop marketing the modified devices. If any of these events occurs or if the FDA takes other enforcement actions, we may not be able to provide our customers with the products they require on a timely basis, our reputation could be harmed, and we could lose customers and suffer reduced revenues and increased costs.

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

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 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 NC-stat DPNCheck and SENSUS systems, and to fully manufacture 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 entered into exclusive manufacturing and supply agreements with Parlex Polymer Flexible Circuits, Inc. for the manufacture of the biosensors for nerve conduction testing for our domestic market. Katecho, Inc. manufactures biosensors for use with our NC-stat DPNCheck devices in international markets and also manufactures electrodes for SENSUS, and Sunburst EMS, Inc. manufactures electronic boards and other components of our NC-stat DPNCheck and SENSUS

TABLE OF CONTENTS

products, which we assemble at our corporate headquarters facility to produce completed devices. Sunburst EMS, Inc. also manufactures our ADVANCE System monitors, docking stations, and communication hubs.

We have experienced transient inventory shortages on new products 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 products as we expand our markets, we could lose customers, our potential future growth could be limited and our business could be harmed.

In order for us to successfully expand our business within the United States and internationally, our contract manufacturers must be able to provide us with substantial quantities of 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 the manufacturers of our products 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.

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

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

TABLE OF CONTENTS

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

Two years ago we shifted our strategy to focus on diabetes care, specifically unmet medical needs related to diabetic peripheral neuropathy which is the most common complication of diabetes. Since then, we have advanced NC-stat DPNCheck and SENSUS through our product development pipeline to the market. We plan to introduce other new products related to diabetic neuropathy, such as SENTINEL, in future periods. 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 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.

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:

We also 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:

TABLE OF CONTENTS

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:

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-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

TABLE OF CONTENTS

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, has been introduced in Congress each year for the past several years but has not yet been enacted. 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.

In February 2009, we announced that we had reached a resolution with the United States Department of Justice, or DOJ, and the OIG of the United States Department of Health and Human Services regarding the previously-disclosed investigation into certain of our past sales and marketing practices relating to our NC-stat System. As part of the resolution with the DOJ and OIG, we entered into a three-year Deferred Prosecution Agreement with the DOJ and a five-year Corporate Integrity Agreement with the OIG. The Deferred Prosecution Agreement has now expired. However, failure to comply with the terms of the Corporate Integrity Agreement could result in substantial civil or criminal penalties and being excluded from government health care programs, which could materially reduce our sales and adversely affect our financial condition 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. Although we do not believe that we are subject to the HIPAA rules, the exact scope of these rules has not been clearly established. 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 NC-stat and ADVANCE systems, NC-stat DPNCheck, and SENSUS 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 eventual outcome, could result in substantial costs to us, a

TABLE OF CONTENTS

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:

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 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; Krishnamurthy Balachandran, our Senior Vice President and Chief Operating Officer, Neurodiagnostics; Guy Daniello, our Senior Vice President of Information Technology; and Michael Williams, Ph.D., our Senior Vice President of Engineering and Chief Technology Officer. We do not maintain key person life insurance policies covering any of our employees. The loss of any of our 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 39 employees as of December 31, 2012, 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 our business has recently faced. 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 new products, such as NC-stat DPNCheck, SENSUS and the ADVANCE System and upgrade 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,

TABLE OF CONTENTS

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.

We currently compete, and may in the future need to compete, against other medical device companies with potentially 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. We 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:

As we develop the market for diagnosis and treatment of diabetic neuropathy, we may be faced with competition from these companies or others that decide and are able to enter this market. Some or all of our future competitors in the diabetes care market may enjoy competitive advantages such as those described above. If we are unable to compete effectively against existing and future competitors, our sales will decline and our business will be harmed.

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

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

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

Future clinical studies or other articles regarding our existing products or any competing products may be published that either support a claim, or are perceived to support a claim, that a competitor’s product is more 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 could endorse products or methods that compete with our products or otherwise announce positions that are unfavorable to

TABLE OF CONTENTS

our products. We have experienced this with the professional societies representing the neurology community. Any of these events may negatively affect our sales efforts and result in decreased revenues.

As we expand into foreign markets, we will be affected by new business risks that may adversely impact our financial condition or results of operations.

Foreign markets represented approximately 7% of our revenues in 2012. We are working to expand market penetration, particularly in Europe and Asia. Any such expansion will subject us to the possibility of new business risks, including:

If we are successful in introducing our products 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 into foreign markets may not be successful, in which case we may have expended significant resources without realizing the expected benefit.

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

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

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. We may not be able to comply with these covenants in the future. Our failure to comply

TABLE OF CONTENTS

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.

If we choose to acquire or invest in new businesses, products or technologies, instead of developing them ourselves, these acquisitions or investments could disrupt our business and could result in the use of significant amounts of equity, cash or a combination of both.

From time to time we may seek to acquire or invest in businesses, products or technologies, instead of developing them ourselves. Acquisitions and investments involve numerous risks, including:

In addition, any future acquisitions or investments may result in one or more of the following:

Any of these factors could materially harm our stock price, our business, or our operating results.

We may be required to raise additional funds to finance our operations and remain a going concern; 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 $8.7 million as of December 31, 2012. We believe that these resources and the cash to be generated from expected product sales will be sufficient to meet our projected operating requirements for at least the next twelve months. 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

TABLE OF CONTENTS

may make in our business strategy; (d) regulatory developments 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 will need to raise additional funds to support our operating and capital needs beyond the next twelve months. 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 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.

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. Any additional sales of shares of our common stock and 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. Since our public offering in July 2004 through February 1, 2013 our stock price has fluctuated from a low of $2.40 to a high of $1,482.84. The market price for our common stock will be affected by a number of factors, including:

TABLE OF CONTENTS

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.

If we fail to meet all applicable NASDAQ Capital Market requirements and The NASDAQ Stock Market determines to delist our common stock, the delisting could adversely affect the market liquidity of our common stock, impair the value of your investment and harm our business.

Our common stock is currently listed on the NASDAQ Capital Market. In order to maintain that listing, we must satisfy minimum financial and other requirements. On March 22, 2012, we received a notice from the Listing Qualifications Department of the NASDAQ Stock Market indicating that, for the last 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 September 18, 2012, to regain compliance with the minimum bid price requirement. On September 19, 2012, we received a letter from NASDAQ stating that we had been granted a six month extension until March 18, 2013 to regain compliance with the minimum bid price requirement for continued listing on The NASDAQ Capital Market. During this grace period extension, our common stock will continue to be listed on The NASDAQ Stock Market. In order to regain compliance, shares of our common stock must maintain a minimum bid closing price of at least $1.00 per share for a minimum of ten consecutive business days.

In order to regain compliance, shares of the our common stock must maintain a minimum bid closing price of at least $1.00 per share for a minimum of ten consecutive business days. Therefore, on February 15, 2013, we filed a Certificate of Amendment to our Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware, to effect a 1-for-6 reverse stock split of our common stock. This action had previously been approved by our stockholders at a special meeting of stockholders held on December 7, 2012. As a result of the reverse stock split, every six shares of our pre-reverse split common stock were combined and reclassified into one share of our common stock. No fractional shares were issued in connection with the reverse stock split.

If we do not regain compliance by March 18, 2013, NASDAQ will provide written notification to us that our common stock will be delisted. At that time, we may appeal NASDAQ’s delisting determination to a NASDAQ Hearings Panel. While we intend to engage in efforts to regain compliance, and thus maintain our

TABLE OF CONTENTS

listing, we may not be able to regain compliance during the applicable time period set forth above. If we fail 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. The closing bid price of our common stock on the NASDAQ Capital Market was $2.88 on February 1, 2013.

Our recently implemented reverse stock split could adversely affect the market liquidity of our common stock, impair the value of your investment and harm our business.

On December 7, 2012, our stockholders approved a proposed amendment to our restated certificate of incorporation, as amended, and authorized our Board of Directors, if in their judgment they deemed it necessary, to effect a reverse stock split of our common stock at a ratio in the range of 1:2 to 1:6. We implemented this reverse stock split on February 15, 2013 with a ratio of 1:6, however, there are risks associated with this reverse stock split, including that the reverse stock split may not result in a sustained increase in the per share price of our common stock. We cannot predict whether the reverse stock split will increase the market price for our common stock on a sustained basis. The history of similar stock split combinations for companies in like circumstances is varied, and we cannot predict whether:

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

Although our common stock is listed on the NASDAQ Capital Market, our common stock has experienced low trading volume. The 50 day average trading volume through February 1, 2013 as reported by NASDAQ was approximately 13,667 shares. Limited trading volume may subject our common stock to greater price volatility and may make it difficult for investors to sell shares at a price that is attractive to them.

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

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

TABLE OF CONTENTS

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 precludes 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.

Market Information

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion of our financial condition and results of operations in conjunction with our selected financial data, our financial statements, and the accompanying notes to those financial statements included elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. For a description of factors that may cause our actual results to differ materially from those anticipated in these forward-looking statements, please refer to the section titled “Risk Factors”, contained in Item 1A of this Annual Report on Form 10-K.

Overview

We are a medical device company focused on the diagnosis and treatment of the neurological complications of diabetes. People with diabetes do not effectively regulate their blood glucose, or sugar, levels leading to chronically high levels of glucose in the blood, called hyperglycemia, and occasionally bouts of low glucose in the blood, called hypoglycemia. The primary reason that glucose levels are not effectively regulated in people with diabetes is that those with the disease do not produce insulin (Type I diabetes) or are resistant to the normal physiological action of insulin (Type II diabetes). Many Type II diabetics eventually require insulin because production of the hormone by their pancreas decreases with time. Type I diabetes usually affects children and teenagers whereas Type II diabetes has typically been a disease of adults over the age of 50. However, over the past decade, Type II diabetes is occurring in younger adults, which can probably be attributed to higher levels of obesity in this age group.

We believe that there are large and important unmet needs in both the diagnosis and treatment of diabetic neuropathies. As a medical device company with both unique and substantial experience in devices to measure and alter peripheral nerve function, we believe we are in the unique position to address the nerve-related complications of diabetes through the development of novel proprietary medical devices. Therefore, we are focused on developing and marketing medical devices for the diagnosis and treatment of diabetic neuropathies. We believe that we are the only medical device company with a strategic focus on the diabetic neuropathy market and our goal is to be the dominant player in this field.

Since we shifted our strategic focus to the diabetic neuropathy market in 2011, we have launched two products with the potential to change medical practice. NC-stat DPNCheck, our diagnostic test for diabetic peripheral neuropathy has now been on the market for over a year since launch in late 2011. Revenues in 2012 were nearly $1.5M. Importantly, we were able to test product acceptance in several market segments and have now focused on the managed care market as the most attractive near-term revenue opportunity. Within managed care, we are specifically targeting Medicare Advantage. Medicare Advantage providers assume financial responsibility and the associated risks for the health care costs of their patients. For Medicare Advantage providers, NC-stat DPNCheck presents a compelling 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 NC-stat DPNCheck helps clarify the patient health profile which, in turn, has a direct, positive effect on the Medicare Advantage premium received by the provider. The Medicare Advantage market encompasses approximately 15 million covered lives or about 27% of the total Medicare population. We believe that this represents an attainable market in the range of $75 and $150 million. We have a small, senior level commercial operations team focused on developing the Medicare Advantage market.

SENSUS, our therapeutic device for relief of chronic, intractable pain was launched in January 2013. We believe this product will be attractive to endocrinologists, podiatrists, primary care physicians, and other physicians that are challenged with trying to manage pain in their patients with painful diabetic neuropathy. The prevalence of painful diabetic neuropathy is 16 – 26% of people with diabetes representing a 4 – 6 million patient group. The attainable market for SENSUS, we believe, could be 10% of this patient group representing annual potential revenue in the range of $150 – $200 million. SENSUS is a prescription product and our initial challenge is to obtain broad, national physician exposure. We intend to create demand by contracting with a number of independent durable medical equipment (DME) suppliers employing sales representatives who detail physicians. Physician prescriptions will be fulfilled by the DME suppliers who will maintain a stock of SENSUS devices and consumables. We have seven regional DME distributors with 30 sales representatives as of February 15, 2013. Our goal in building national coverage is 100 sales

TABLE OF CONTENTS

representatives by mid-2013 and 250 sales representatives by the end of 2013. Further, during 2013 we have set a goal of 2,000 patients treated with SENSUS resulting in $1 million in product revenue.

During the course of 2012 we modified our operating structure to focus more narrowly on the high-value opportunities for NC-stat DPNCheck and SENSUS that can be pursued via independent distributors plus a small commercial operations team. This has reduced operating expenses and, more significantly, improved our future flexibility to generate increased sales volume without the cost of adding sales representatives and field clinical support. Our operating expenses during 2012 totaled $14.0 million. We forecast 2013 operating expenses to be in the range of $11 to $12 million, a reduction of 14% to 21%. We believe we can maintain and leverage this approximate operating expense level over the next several years as our diabetes business grows.

We continue to manage our historical neurodiagnostics business which is centered on the ADVANCE system. This business generated $6.1 million in revenue during 2012 with gross margins exceeding 50%. There are few direct cash operating expenses of the business. The neurodiagnostic business has been in decline for several years and reimbursement conditions that might lead to reversing the trend are not existent. We see this business as continuing to decline as we operate it for cash flow.

Results of Operations

Comparison of Years Ended December 31, 2012 and December 31, 2011

Revenues

The following table summarizes our revenues:

		Years Ended December 31,
		2012				2011				Change				% Change
		(in thousands)
Revenues		$	7,575.3			$	10,396.8			$	(2,821.5	)			(27.1	)%

Revenues include sales from our initial diabetes product, NC-stat DPNCheck which was commercially launched late in 2011, and our legacy neurodiagnostics business. During the year ended December 31, 2012 we shipped 836 NC-stat DPNCheck devices plus consumable biosensors and recorded revenue from these products of $1,443,000. This compares with NC-stat DPNCheck revenue of $84,800 for the year ended December 31, 2011. Revenues from medical device and consumables sales of our legacy neurodiagnostic products totaled $6.1 million in 2012, compared to $10.3 million in 2011. The $4.2 million reduction in neurodiagnostics revenue reflects the continuing decline of this business which we manage for cash flow and not growth. In addition, neurodiagnostic revenue in 2012 was adversely affected by our discontinuance of service to older NC-stat products linked to our onCall system. While many NC-stat accounts transitioned to the ADVANCE platform, we did experience a drop in testing accounts shortly after we shut down the onCall system.

Cost of Revenues and Gross Margin

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

		Years Ended December 31,
		2012				2011				Change				% Change
		(in thousands)
Cost of revenues		$	3,588.8			$	4,722.1			$	(1,133.3	)			(24.0	)%
Gross profit		$	3,986.5			$	5,674.7			$	(1,688.2	)			(29.7	)

Our cost of revenues decreased $1.1 million to $3.6 million, or 47.4% of revenues, for the year ended December 31, 2012, compared to $4.7 million, or 45.4% of revenues for the year ended December 31, 2011. Included in cost of revenues in 2012 was $234,800 in non-cash charges for excess inventory related to our neurodiagnostics business. Our gross margin percentage of 52.6% of revenues for 2012 decreased from 54.6% of revenues for 2011. The decreased gross margin percentage in 2012 reflected in part discounts and promotions aimed at expanding market penetration, as well as non-cash charges to write-off excess inventory.

Total operating expenses		$	14,008.5			$	15,677.7			$	(1,669.2	)			(10.6	)

Research and Development

Research and development expenses for the years ended December 31, 2012 and 2011 were $3.5 million and $3.9 million, respectively. The comparative results included decreases of $214,100 in technology licenses and fees as we narrowed our product development focus, $192,500 related to intangible asset impairment charges, $120,000 in recruiting costs for new hires in 2011, $58,800 in stock-based compensation, and $54,000 in depreciation and amortization. These decreases were partially offset by a $187,000 increase in personnel costs as we increased headcount to support development of SENSUS and product modifications to NC-stat DPNCheck, plus a $136,300 increase in engineering fees related to these new products.

Sales and Marketing

Sales and marketing expenses decreased to $5.7 million for the year ended December 31, 2012 from $6.7 million for the year ended December 31, 2011. During 2012, we reduced our dependence on field clinical educators to support our neurodiagnostic business and we shifted our NC-stat DPNCheck emphasis toward managed care allowing us to eliminate our endrocrinolgy/podiatry direct sales representatives. Total sales and marketing headcount was reduced by 18 positions as a result. Personnel costs, including compensation, benefits and recruiting costs in 2012 were $967,500 lower than in 2011. This spending reduction was partially offset by an increase of $101,100 for outside consulting support related to international markets and for U.S. distribution channel development for SENSUS.

General and Administrative

General and administrative expenses decreased to $4.7 million for the year ended December 31, 2012 from $5.1 million for the year ended December 31, 2011. Personnel costs were reduced in 2012 with $348,100 attributable to stock compensation and $142,900 attributable to incentive compensation. Insurance costs were reduced by $90,300 due to a lower coverage amount and reduced insurance rates. Bad debt expense and customer credit processing fees were reduced by $98,300. The Company expanded investor outreach and publicity which increased costs by $196,000.

Interest and other income

Interest income was $14,500 and $21,900 for the years ended December 31, 2012 and 2011, respectively. Interest income was earned from investments in cash equivalents.

Comparison of Years Ended December 31, 2011 and December 31, 2010

Revenues

The following table summarizes our revenues:

		Years Ended December 31,
		2011				2010				Change				% Change
		(in thousands)
Revenues		$	10,396.8			$	13,899.7			$	(3,502.9	)			(25.2	)%

TABLE OF CONTENTS

Revenues include sales of medical equipment consisting of sales of the ADVANCE device and, in 2010, the NC-stat device, accessories, extended service agreements, and sales of consumables consisting of various electrodes, which are used with our ADVANCE and NC-stat Systems, and EMG needles which are used with our ADVANCE System. In 2011, revenues also included $85,000 from sales of our initial diabetes product, NC-stat DPNCheck, which was launched in late 2011. Revenues for the year ended December 31, 2011 declined $3.5 million to $10.4 million, compared with $13.9 million for the year ended December 31, 2010, reflecting a 22.7% contraction of our neurodiagnostic installed base that contributed to lower electrodes sales.

Cost of Revenues and Gross Margin

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

		Years Ended December 31,
		2011				2010				Change				% Change
		(in thousands)
Cost of revenues		$	4,722.1			$	7,050.2			$	(2,328.1	)			(33.0	)%
Gross margin		$	5,674.7			$	6,849.5			$	(1,174.8	)			(17.2	)

Our cost of revenues decreased $2.3 million to $4.7 million, or 45.4% of revenues for the year ended December 31, 2011, compared with $7.1 million, or 50.7% of revenues, for the year ended December 31, 2010. This decrease was due primarily to lower neurodiagnostic shipment volume, partially offset by the impact of higher electrode costs, which increased due to lower production volumes, compared with the year ended December 31, 2010. In addition, gross margin for 2010 included inventory charges of $1.8 million related to a strategic change in direction of our business that was announced on January 4, 2011. Our gross margin of 54.6% of revenues for the year ended December 31, 2011 increased from 49.3% of revenues for the same period in 2010. The lower gross margin percentage for 2010 resulted primarily from the inventory charges noted above.

Operating Expenses

Total operating expenses		$	15,677.7			$	24,159.4			$	(8,481.7	)			(35.1	)

Research and Development

Research and development expenses for the years ended December 31, 2011 and 2010 were $3.9 million and $5.9 million, respectively. The comparative results included decreases of $1.1 million in personnel related costs, $411,000 in clinical studies and product development costs, $315,000 in costs of consulting and outside services, $125,000 for licenses and fees, $124,000 for stock-based compensation, $53,000 for amortization of intangible assets, $50,000 for facilities costs, and $39,000 for supplies and equipment costs. These decreases were partially offset by an impairment charge of $192,500 in the second quarter of 2011 to write off the remaining value of intangible assets following our decision to terminate development efforts relating to certain technological and intellectual property assets acquired in 2009, and a $101,000 increase in recruiting costs.

Sales and Marketing

Sales and marketing expenses decreased to $6.7 million for the year ended December 31, 2011 from $11.1 million for the year ended December 31, 2010. Personnel costs decreased $3.4 million and travel and entertainment costs decreased $764,000 reflecting the January 2011 termination of our direct neurodiagnostics sales force in conjunction with a strategic initiative to more efficiently focus on our installed base of active accounts, partially offset by the implementation of a lower cost sales force focused on the endocrinology and

TABLE OF CONTENTS

podiatry markets beginning in the third quarter of 2011. In addition, recruiting costs decreased $276,000, internal meeting costs decreased $135,000, and stock-based compensation decreased $93,000. These decreases were partially offset by increases of $170,000 in advertising and promotions costs and consulting costs of $76,000 largely related to our diabetes initiative.

General and Administrative

General and administrative expenses decreased to $5.1 million for the year ended December 31, 2011 from $7.2 million for the year ended December 31, 2010. This decrease included $625,000 from personnel costs, reflecting reduced headcount, $500,000 from professional fees, $242,000 from insurance costs, $143,000 from supplies and equipment costs, $131,000 from stock-based compensation, $121,000 from taxes, licenses and fees, $105,000 from bad debt expense, $95,000 from facilities costs, $57,000 from consulting and temporary labor costs, and $45,000 from recruiting costs.

Interest and other income

The following table presents a breakdown of our other income and expenses:

		Years Ended December 31,
		2011				2010				Change				% Change

Total other income and expenses		$	21.9			$	298.3			$	(276.4	)			(92.7	)

Interest income was $22,000 for the year ended December 31, 2011 and $54,000 for the year ended December 31, 2010. In addition, in 2010 we received a $244,000 U.S. Qualifying Therapeutic Discovery Project grant under section 48D of the Internal Revenue Code.

Liquidity and Capital Resources

Our principal source of liquidity is our cash and cash equivalents. As of December 31, 2012, cash and cash equivalents totaled $8.7 million. Our ability to generate revenue will largely depend on the success of our diabetes business initiative and our ability to manage our legacy neurodiagnostic business to optimize cash flow. A low level of market interest in NC-stat DPNCheck or SENSUS, an accelerating 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, 2012				December 31, 2011				Change				% Change
		($ in thousands)
Cash and cash equivalents		$	8,699.5			$	10,290.4			$	(1,590.9	)			(15.5	)%

In order to supplement our access to capital, we are party to a Loan and Security Agreement, or the credit facility, with a bank. As of December 31, 2012 the credit facility permitted us to borrow up to $7.5 million on a revolving basis. The credit facility was recently amended on January 28, 2013 and the amount of the credit facility was set at $2.5 million. The amended credit facility was extended, until its new expiry date of January 31, 2014. 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 secured by our cash, accounts receivable, inventory, and equipment. The credit facility includes traditional lending and reporting covenants. These include certain financial covenants applicable to liquidity that are to be maintained by us. As of December 31, 2012, we were in compliance with these covenants and had not borrowed any funds under the credit facility. The amount of $225,000 of the credit facility limit is restricted to support a letter of credit issued in favor of our landlord in connection with the lease of our facilities in Waltham, Massachusetts. Consequently, the amount available for borrowing under the credit facility as of December 31, 2012 was $7,275,000 and was subsequently reduced to $2,275,000 on January 28, 2013, as noted above.

TABLE OF CONTENTS

During the year ended December 31, 2012, our cash and cash equivalents decreased by $1.6 million, primarily due to net cash of $9.2 million used in operating activities, which was largely offset by net proceeds of $7.5 million provided by our public offering in February 2012. In connection with this public offering, we issued 1,421,735 shares of common stock and warrants to purchase 710,868 shares of common stock and received offering proceeds, net of discounts, commissions and expenses, of approximately $7.5 million. In addition, the placement agent for the offering was issued warrants to purchase 71,087 shares of common stock.

In managing our working capital, two of the financial measurements we monitor are days sales outstanding, or DSO, and inventory turnover rate, which are presented in the table below for the years ended December 31, 2012 and 2011:

		Years Ended December 31,
		2012				2011
Days sales outstanding (days)			33				40
Inventory turnover rate (times per year)			3.2				2.4

The improvement in DSO reflects continuing vigilance in managing customer collections and increased up-front payments. The improvement in inventory turnover reflects continuing vigilance in managing inventory balances.

Our operating activities used $9.2 million in the year ended December 31, 2012. The primary driver for the use of cash in our operating activities during 2012 was our net loss of $10.0 million. This net loss included non-cash charges of $319,400 for stock-based compensation, $297,100 for depreciation and amortization, and $234,800 for an excess inventory provision. In addition, cash used in operating activities reflected working capital changes including a $694,300 decrease in inventories, a $530,100 decrease in accrued expenses and compensation, a $371,900 decrease in accounts payable, and a $343,300 decrease in accounts receivable.

During the year ended December 31, 2012, our investing activities included a $229,500 benefit in the release of formerly restricted cash upon the signing of an amendment to our facility lease, partially offset by $107,500 spent for the acquisition of fixed assets.

During the year ended December 31, 2012, our financing activities included $7.5 million in net proceeds from our public offering of equity securities in February 2012.

We held cash and cash equivalents of $8.7 million as of December 31, 2012. We believe that these resources and the cash to be generated from expected product sales will be sufficient to meet our projected operating requirements for at least the next twelve months. We continue to face significant challenges and uncertainties and, as a result, our available capital resources may be consumed more rapidly than currently expected due to (a) decreases in sales of our products and the uncertainty of future revenues from new products; (b) changes we may make to the business that affect ongoing operating expenses; (c) changes we may make in our business strategy; (d) regulatory developments affecting our existing products and delays in the FDA approval process for products under development; (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 will need to raise additional funds to support our operating and capital needs beyond the next twelve months. 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. We have filed a shelf registration statement with the SEC to register 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. Pursuant to the instructions to Form S-3, we currently 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 the common stock held by non-affiliates. If we issue equity or debt securities to raise additional funds, our existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of our existing stockholders. If we raise additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to our potential products or proprietary technologies, or grant licenses on terms that are not favorable to us. Without additional funds, we may be forced to delay, scale back or eliminate some of our sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue our operations. If any of these events occurs, our ability to achieve our development and commercialization goals would be adversely affected.

As of December 31, 2012, we have federal and state net operating loss, or NOL, carryforwards available to offset future taxable income of $89.4 million and $38.0 million, respectively, and federal and state tax credits of $1.0 million and $901,000, respectively, which may be available to reduce future taxable income and the related taxes thereon. The federal NOL’s begin to expire in 2019 and the state NOL’s begin to expire in 2013. The federal and state research and development 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, 2012, we did not have any off-balance sheet financing arrangements.

The following table summarizes our principal contractual obligations as of December 31, 2012 and the effects such obligations are expected to have on our liquidity and cash flows in future periods.

As of December 31, 2012, we have no contractual obligations that extend beyond two years.

Critical Accounting Policies and Estimates

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

Revenue Recognition and Accounts Receivable

We recognize revenue 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.

TABLE OF CONTENTS

Revenues associated with the sale of the ADVANCE devices to customers and distributors are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, product returns are reasonably estimable, and no continuing obligations exist. The revenues from the sale of an ADVANCE communication hub together with access to NeuroMetrix information systems are considered one unit of accounting and deferred and recognized on a straight-line basis over the estimated period of time that we provide the service associated with the information systems of three years. The resulting deferred revenue and deferred costs are presented as separate line items on the accompanying balance sheet. Revenues related to extended service agreements for the devices are recognized ratably over the term of the extended service agreement.

Revenues associated with the sale of the NC-stat DPNCheck devices are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, product returns are reasonably estimable, and no continuing obligations exist.

Revenues also include sales of consumables, including single use nerve specific electrodes, EMG needles, and other accessories. These revenues are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, and product returns are reasonably estimable.

When multiple elements are contained in a single arrangement, we allocate revenue between the elements based on their relative selling prices. We determine selling price using vendor specific objective evidence, or VSOE, if it is available, third-party evidence, or TPE, if VSOE is not available, and best estimate of selling price, or BESP, if neither VSOE nor TPE are available. We generally expect that we will not be able to establish TPE due to the nature of the markets in which we compete, and, as such, we will typically determine selling price using VSOE or if not available, BESP. The objective of BESP is to determine the selling price of a deliverable on a standalone basis. Our determination of BESP involves a weighting of several factors based on the specific facts and circumstances of an arrangement. Specifically, we consider the cost to produce the deliverable, the anticipated margin on that deliverable, the selling price and profit margin for similar parts, our ongoing pricing strategy, the value of any enhancements that have been built into the deliverable, and the characteristics of the varying markets in which the deliverable is sold.

Revenue recognition involves judgments, including assessments of expected returns and expected customer relationship periods. We analyze various factors, including a review of specific transactions, our historical 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 our estimate.

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Certain product sales are made with a 30-day right of return. Since we can reasonably estimate future returns, we recognize revenues associated with product sales that contain a right of return upon shipment and at the same time we record a sales return reserve, which reduces revenue and accounts receivable by the amount of estimated returns.

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 collectibility. 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.

TABLE OF CONTENTS

Inventories

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-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 May 2011, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2011-04, “Fair Value Measurement (Topic 820) — Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS”, or ASU 2011-04. The amendments in ASU 2011-04 result in common fair value measurement and disclosure requirements in GAAP and International Financial Reporting Standards, or IFRS. Consequently, the amendments change the wording used to describe many of the requirements in GAAP for measuring fair value and for disclosing information about fair value measurements. We adopted this new guidance prospectively beginning on January 1, 2012. Adoption has not had a material effect on our financial statements.

In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220) — Presentation of Comprehensive Income”, or ASU No. 2011-05. ASU No. 2011-05 requires that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements, eliminating the option to present other comprehensive income in the statement of changes in equity. Under either choice, items that are reclassified from other comprehensive income to net income are required to be presented on the face of the financial statements where the components of net income and the components of other comprehensive income are presented. In December 2011, the FASB issued ASU No. 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05”, which defers the requirement within ASU No. 2011-05 to present on the face of the financial statements the effects of reclassifications out of accumulated other comprehensive income on the components of net income and other comprehensive income for all periods presented. During the deferral, entities should continue to report reclassifications out of accumulated other comprehensive income consistent with the presentation requirements in effect prior to the issuance of ASU No. 2011-05. We adopted this new guidance retrospectively beginning on January 1, 2012. Adoption has not had a material effect on our financial statements.

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

There have been no changes in or disagreements with accountants on accounting and financial disclosure matters in the last fiscal year.

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. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that 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, 2012 based on the criteria in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway

TABLE OF CONTENTS

Commission (“COSO”). Based on our evaluation under the framework in Internal Control — Integrated Framework issued by the COSO, our management concluded that our internal control over financial reporting was effective as of December 31, 2012.

This Annual Report 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.

(c) Changes in internal control over financial reporting.

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, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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 I, Class II and Class III directors expiring upon the election and qualification of directors at the annual meetings of stockholders to be held in 2014, 2015, and 2013, respectively. Currently:

Our Board of Directors has determined that Dr. Goodman, Dr. Hinkle, Mr. Surgenor, and Ms. Katz 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.

TABLE OF CONTENTS

The Audit Committee currently consists of Mr. Surgenor, Chairman, and 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.

Procedures by which Stockholders may Nominate Directors

There have been no changes to the procedures disclosed in our proxy statement for the 2012 annual meeting of stockholders by which stockholders may nominate directors.

Code of Business Conduct and Ethics

We have adopted a Code of Business Conduct and Ethics that applies to all of our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller and persons performing similar functions. A current copy of the Code of Business Conduct and Ethics is available on our website at http://www.neurometrix.com under the heading “Investor Relations” and subheading “Corporate Governance,” and we intend to disclose on this website any amendment to, or waiver of, any provision of the Code of Business Conduct and Ethics applicable to our directors or executive officers that would otherwise be required to be disclosed under the SEC rules, to the extent permitted, by the NASDAQ rules. A current copy of the Code of Business Conduct and Ethics may also be obtained, without charge, upon written request directed to us at: NeuroMetrix, Inc., 62 Fourth Avenue, Waltham, Massachusetts 02451, Attention: Compliance Officer.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors and executive officers and holders of more than 10% of our common stock (collectively, “Reporting Persons”) to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock. 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, except that 5 Forms 4 were not filed on a timely basis as a result of administrative error for one transaction for each of Krishnamurthy Balachandran, Guy Daniello, Dr. Shai N. Gozani, Thomas T. Higgins, and Dr. Michael Williams in connection with the surrender of restricted shares upon vesting of such restricted shares to pay taxes.

ITEM 11. Executive Compensation

The information required by this Item will be contained in our definitive proxy statement for our 2013 Annual Meeting of Stockholders under the captions “Compensation of Executive Officers” and “Director Compensation Table – 2012” and is incorporated by reference herein.

ITEM 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

PRINCIPAL AND MANAGEMENT STOCKHOLDERS

The following table sets forth certain information concerning beneficial ownership as of February 1, 2013, except as noted below, of our common stock by:

TABLE OF CONTENTS

The number of common shares “beneficially owned” by each stockholder is determined under rules issued by the SEC regarding the beneficial ownership of securities. This information is not necessarily indicative of beneficial ownership for any other purpose. Under these rules, beneficial ownership of common stock includes (1) any shares as to which the person or entity has sole or shared voting power or investment power and (2) any shares as to which the person or entity has the right to acquire beneficial ownership within 60 days after February 1, 2013, including any shares that could be purchased by the exercise of options or warrants on or within 60 days after February 1, 2013. Each stockholder’s percentage ownership is based on 2,140,871 shares of our common stock outstanding as of February 1, 2013 plus the number of shares of common stock that may be acquired by such stockholder upon exercise of options or warrants that are exercisable on or within 60 days after February 1, 2013.

Unless otherwise indicated below, to our knowledge, all persons named in the table have sole voting and investment power with respect to their shares of common stock, except to the extent authority is shared by spouses under community property laws.

Report of Independent Registered Public Accounting Firm

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

In our opinion, the accompanying balance sheets and the related statements of operations, of changes in stockholders’ equity, and of cash flows present fairly, in all material respects, the financial position of NeuroMetrix, Inc. at December 31, 2012 and December 31, 2011, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2012 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(1) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related financial statements. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

1. Description of Business and Basis of Presentation

NeuroMetrix, Inc., or the Company, a Delaware corporation, was founded in June 1996. The Company is a medical device company focused on the diagnosis and treatment of the neurological complications of diabetes. The Company believes that its substantial experience in developing medical devices to stimulate and measure peripheral nerve function uniquely position it to address unmet medical needs related to diabetic neuropathy. Neuropathy is a common and serious, often painful, complication of diabetes that may lead to foot ulcers and limb amputation. The Company has over a decade of experience in neuropathy detection starting with approval in 1998 by the United States Food and Drug Administration, or FDA, of the NC-stat System, a point-of-care device for the performance of general purpose nerve conduction studies. The Company currently markets products for the detection, diagnosis, monitoring and treatment of diabetic neuropathies such as diabetic peripheral neuropathy and median neuropathy (carpal tunnel syndrome).

The Company launched NC-stat DPNCheck in late 2011. NC-stat DPNCheck is a fast, accurate, and quantitative nerve conduction test for diabetic peripheral neuropathy designed to be used at the point of care. Sales efforts for NC-stat DPNCheck are currently targeted at opportunities in the managed care market. In the first quarter of 2013, the Company completed product development and launched the SENSUS pain management system which is designed for relief of chronic, intractable pain. The Company believes this product will be attractive to endocrinologists, podiatrists, primary care and other physicians that are challenged with trying to manage pain in their patients with painful diabetic neuropathy. The Company’s historical neurodiagnostic business is based on the ADVANCE^TM NCS/EMG System, or the ADVANCE System, which is a comprehensive platform for the performance of traditional nerve conduction studies and invasive electromyography procedures and which is primarily used in physician offices and clinics. The ADVANCE System contributes the majority of the Company’s revenues.

The Company held cash and cash equivalents of $8.7 million as of December 31, 2012. The Company believes that these resources and the cash to be generated from expected product sales will be sufficient to meet its projected operating requirements for at least the next twelve months. 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 and delays in the FDA approval process for products under development; (e) changes in the Company’s 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 will need to raise additional funds to support its operating and capital needs beyond the next twelve months. The Company 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, the Company may not be able to secure such financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity or debt securities to raise additional funds, its existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders. If the Company raises additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products or proprietary technologies, or grant licenses on terms that are not favorable to the Company. Without additional funds, the Company may be forced to delay, scale back or eliminate some of its sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue its operations. If any of these events occurs, the Company’s ability to achieve its development and commercialization goals would be adversely affected.

Certain prior period amounts have been adjusted to reflect the Company's 1-for-6 reverse stock split of its common stock completed on February 15, 2013 (see Note 15, Reverse Stock Splits, for further details).

2. Summary of Significant Accounting Policies

Use of Estimates and Assumptions

The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during reporting periods. Actual results could differ from those estimates.

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

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, 2012, one customer accounted for 11.5% of accounts receivable. For the years ended December 31, 2012, 2011, and 2010, no single customer accounted for more than 10% of revenue.

The Company relies on in-house assembly and three 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 purchased components, are stated at the lower of cost or market. 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 financial instruments, which include cash equivalents, accounts receivable, accounts payable, and accrued expenses approximate their fair value at December 31, 2012 and 2011.

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 sale of the ADVANCE devices to customers and distributors are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, product returns are reasonably estimable, and no

continuing obligations exist. The revenues from the sale of an ADVANCE communication hub together with access to NeuroMetrix information systems are considered one unit of accounting and deferred and recognized on a straight-line basis over the estimated period of time that the Company provides the service associated with the information systems of three years. The resulting deferred revenue and deferred costs are presented as separate line items on the accompanying balance sheet. Revenues related to extended service agreements for the devices are recognized ratably over the term of the extended service agreement.

Revenues associated with the sale of the NC-stat DPNCheck devices are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, product returns are reasonably estimable, and no continuing obligations exist.

Revenues also include sales of consumables, including single use nerve specific electrodes, EMG needles, and other accessories. These revenues are recognized upon shipment provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, and product returns are reasonably estimable.

When multiple elements are contained in a single arrangement, the Company allocates revenue between the elements based on their relative selling prices. The Company determines selling price using vendor specific objective evidence, or VSOE, if it is available, third-party evidence, or TPE, if VSOE is not available, and best estimate of selling price, or BESP, if neither VSOE nor TPE are available. The Company generally expects that it will not be able to establish TPE due to the nature of the markets in which it competes, and, as such, it will typically determine selling price using VSOE or if not available, BESP. The objective of BESP is to determine the selling price of a deliverable on a standalone basis. The Company’s determination of BESP involves a weighting of several factors based on the specific facts and circumstances of an arrangement. Specifically, the Company considers the cost to produce the deliverable, the anticipated margin on that deliverable, the selling price and profit margin for similar parts, its ongoing pricing strategy, the value of any enhancements that have been built into the deliverable, and the characteristics of the varying markets in which the deliverable is sold.

Revenue recognition involves judgments, including assessments of expected returns and expected customer relationship periods. The Company analyzes various factors, including a review of specific transactions, its historical returns, average customer relationship periods, customer usage, customer balances, and market and economic conditions. Changes in judgments or estimates on these factors could materially impact the timing and amount of revenues and costs recognized. Should market or economic conditions deteriorate, the Company’s actual return or bad debt experience could exceed its estimate.

Certain product sales are made with a 30-day right of return. Since the Company can reasonably estimate future returns, it recognizes revenues associated with product sales that contain a right of return upon shipment and at the same time it records a sales return reserve, which reduces revenue and accounts receivable by the amount of estimated returns.

Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Accounts receivable on the balance sheet are recorded net of the allowance for doubtful accounts receivable and the reserve for estimated returns. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in its existing accounts receivable. The Company reviews its allowance for doubtful accounts and determines the allowance based on an analysis of customer past payment history, product usage activity, and recent communications between the Company and the customer. Past due balances are reviewed individually for collectibility. 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 its 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 the research and development of the Company’s products 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.

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 $18,629 and $32,308 at December 31, 2012 and 2011, respectively, are included in accrued expenses in the accompanying balance sheets.

2. Summary of Significant Accounting Policies  – (continued)

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 Equity).

Net Loss per Common Share

Basic net loss per common share is computed by dividing net loss 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 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 outstanding instruments such as options, warrants, and restricted 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, the following shares underlying potentially dilutive common stock equivalents were excluded from the calculation of diluted net income per common share because their effect was anti-dilutive for each of the periods presented:

		Years Ended December 31,
		2012				2011				2010
Options			53,999				91,411				89,079
Warrants			741,546				238,413				238,413
Unvested restricted stock			31,699				4,725				1,484
Total			827,244				334,549				328,976

Warrants outstanding at December 31, 2012 were issued in the public offering completed on February 13, 2012 (see Note 14, Public Offering of Common Stock and Warrants, for further details). Warrants outstanding at December 31, 2011 and 2010 were redeemed in March 2012 in exchange for 23,127 shares of common stock.

Advertising and Promotional Costs

Advertising and promotional costs are expensed as incurred. Advertising and promotion expense was $242,000, $426,000, and $256,000 in the years ended December 31, 2012, 2011, and 2010, respectively.

Accumulated Other Comprehensive Items

For the years ended December 31, 2012, 2011, and 2010, 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 the years ended December 31, 2012, 2011, and 2010 were located at or derived from operations in the United States. Revenues from sales outside the United States accounted for approximately 7% of total revenues in 2012, 6% of total revenues in 2011, and 2% of total revenues in 2010.

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.

In late 2011, the Company launched NC-stat DPNCheck, which is a fast, accurate, and quantitative nerve conduction test for the assessment of systemic neuropathies such as DPN. In early 2013 the Company launched SENSUS for the treatment intractable pain, including pain associated with diabetic neuropathy. The future prospects of the Company are closely tied to its success with NC-stat DPNCheck and SENSUS in market acceptance and growth in future revenues.

Recently Issued or Adopted Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2011-04, “Fair Value Measurement (Topic 820) — Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS”, or ASU 2011-04. The amendments in ASU 2011-04 result in common fair value measurement and disclosure requirements in GAAP and International Financial Reporting Standards, or IFRS. Consequently, the amendments change the wording used to describe many of the requirements in GAAP for measuring fair value and for disclosing information about fair value measurements. The Company adopted this new guidance prospectively beginning January 1, 2012. Adoption has not had a material effect on the Company’s financial statements.

In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220) — Presentation of Comprehensive Income”, or ASU No. 2011-05. ASU No. 2011-05 requires that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements, eliminating the option to present other comprehensive income in the statement of changes in equity. Under either choice, items that are reclassified from other comprehensive income to net income are required to be presented on the face of the financial statements where the components of net income and the components of other comprehensive income are presented. In December 2011, the FASB issued ASU No. 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05”, which defers the requirement within ASU No. 2011-05 to present on the face of the financial statements the effects of reclassifications out of accumulated other comprehensive income on the components of net income and other comprehensive income for all periods presented. During the deferral, entities should continue to report reclassifications out of accumulated other comprehensive income consistent

with the presentation requirements in effect prior to the issuance of ASU No. 2011-05. The Company adopted this new guidance retrospectively beginning January 1, 2012. Adoption has not had a material effect on the Company’s financial statements.

3. Stock-Based Compensation and Stockholders’ Equity

Stock-Based Compensation

During 2004, the Company adopted the 2004 Stock Option and Incentive Plan, as amended and restated in 2006, 2008 and 2009. At the Annual Meeting of Stockholders held on May 14, 2012, the stockholders of the Company approved the Company’s Fourth 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 166,667 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, 2012, 276,279 shares of common stock were authorized for issuance under the 2004 Stock Plan, of which 9,272 shares had been issued, 47,907 shares were subject to outstanding options at a weighted average exercise price of $72.06 per share and 176,882 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, 2012, 13,889 shares of common stock were authorized for issuance under the 2009 Inducement Plan, of which no shares had been issued, 2,083 shares were subject to outstanding options at a weighted average exercise price of $9.60 per share, and 11,806 shares were available for future grant.

The exercise price of each stock option issued under the 1996 and 1998 Stock Plans was specified by the Board of Directors at the time of grant. The exercise price of stock options awarded under the 2004 Stock Plan and the 2009 Inducement Plan may not be less than the fair market 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 market 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 10,417 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 6,945 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) 6,945 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. At the Company’s Annual Meeting of Stockholders held on May 14, 2012, the stockholders of the Company approved the Company’s Amended and Restated 2010 Employee Stock Purchase Plan (the “Amended and Restated 2010 ESPP”), which, among other things, increased the number of shares of the Company’s common stock authorized for issuance thereunder by 16,667 shares. 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 market 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, 2012 and 2011 the Company issued 8,895 and 4,090 shares of its common stock, respectively, under the Amended and Restated 2010 ESPP and the 2010 ESPP, respectively. As of December 31, 2012, there were 21,765 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 used in the calculation of stock-based compensation expense in the accompanying statement of operations for the years ended December 31, 2012, 2011, and 2010 is calculated using the following assumptions:

		Years Ended December 31,
		2012				2011				2010
Risk-free interest rate			0.6% – 0.9	%			0.9% – 2.3	%			1.0% – 2.8	%
Expected dividend yield			—				—				—
Expected option term			5 years				5 – 6 years				5 years
Volatility			70.0%				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 and a review of comparable medical device companies. The volatility assumption is based on weekly historical volatility during the time period that corresponds to the expected option term, a review of comparable medical device companies 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, 2012 is presented below:

		Number of Options				Weighted Average Exercise Price				Weighted Average Remaining Contractual Life (in years)				Aggregate Intrinsic Value
Outstanding at December 31, 2011			56,433			$	80.82
Granted			617				4.62
Exercised			—				—
Forfeited			(5,391	)			143.40
Expired			(109	)			81.00
Outstanding at December 31, 2012			51,550				73.38				6.80			$	—

Exercisable at December 31, 2012			40,784				85.62				6.49				—

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, 2012, 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, 2012.

The weighted average per share grant-date fair values of options granted during the years ended December 31, 2012, 2011, and 2010 was $2.67, $11.34, and $28.44, respectively.

The aggregate intrinsic value of options issued or exercised during the years ended December 31, 2012, 2011, and 2010 was $0, $0, and $3,000, respectively.

Total unrecognized stock-based compensation costs related to non-vested stock options was $251,747, which related to 49,043 shares with a per share weighted fair value of $5.16 as of December 31, 2012. This unrecognized cost is expected to be recognized over a weighted average period of approximately 0.6 years.

Stock options granted to non-employees are recorded at fair value and adjusted to market over the vesting period. The Company determines fair value using the Black-Scholes option pricing model, an expected term equal to the option term, a risk-free interest rate corresponding to the expected term, a stock price volatility over the most recent period of time corresponding to the expected term and also based on expected future stock price volatility, and a dividend yield of zero. There were no options granted to non-employees during the year ended December 31, 2012.

Beginning in 2010, certain employees have been granted restricted stock. During 2012, 2011, and 2010, the Company granted 37,167, 3,630, and 2,616 shares of restricted stock, respectively. The fair value of restricted stock is calculated based on the closing sale price of the Company’s common stock on the date of issuance.

A summary of restricted stock activity for the year ended December 31, 2012 is presented below:

		Restricted Shares				Weighted Average Grant Date Fair Value
Restricted shares at December 31, 2011			4,488			$	28.32
