Notes to Unaudited Financial Statements

June 30, 2020

1. Business and Basis of Presentation

Our Business-An Overview

NeuroMetrix, Inc., or the Company, is a leading developer and manufacturer of diagnostic and therapeutic neurostimulation based medical devices that are used throughout the world. The Company has three FDA cleared commercial products. DPNCheck® is a point-of-care test that is used to evaluate peripheral neuropathies. ADVANCE^™ is a point-of-care device that provides nerve conduction studies as an aid in diagnosing and evaluating patients suspected of having focal or systemic neuropathies. Quell^® 2.0 is a wearable, mobile app enabled, neurostimulation device indicated for symptomatic relief and management of chronic pain and is available OTC. The Company maintains an active, industry-leading R&D program.

The accompanying financial statements have been prepared on a basis which assumes that the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. The Company has reported recurring losses from operations and negative cash flows from operating activities. At June 30, 2020, the Company had an accumulated deficit of $196.3 million. These factors raise substantial doubt about the Company’s ability to continue as a going concern for the one-year period from the date of issuance of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company held cash and cash equivalents of $5.4 million as of June 30, 2020. The Company believes that these resources and the cash to be generated from future product sales will be sufficient to meet its projected operating requirements into the third quarter of 2021. Accordingly, the Company will need to raise additional funds to support its operating and capital needs in the third quarter of 2021 and beyond.

The Company continues to face significant challenges and uncertainties. Among these uncertainties is the future effect on the Company's business of the COVID-19 pandemic which, in late first quarter of 2020 and throughout the second quarter of 2020, depressed sales of the Company's products. 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, including decreases in customer orders related to the COVID-19 pandemic, and the uncertainty of future revenues from new products; (b) the effect of the COVID-19 pandemic on the Company's ability to obtain parts and materials from the Company's suppliers while continuing to staff critical production and fulfillment functions; (c) changes the Company may make to the business that affect ongoing operating expenses; (d) changes the Company may make in its business strategy; (e) regulatory developments affecting the Company’s existing products; (f) changes the Company may make in its research and development spending plans; and (g) other items affecting the Company’s forecasted level of expenditures and use of cash resources.

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 funding 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.

Unaudited Interim Financial Statements

The accompanying unaudited balance sheet as of June 30, 2020, unaudited statements of operations, changes in stockholders' equity and cash flows for the quarters and six months ended June 30, 2020 and 2019 have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. The accompanying balance sheet as of December 31, 2019 has been derived from audited financial statements prepared at that date, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the financial statements include all normal and recurring adjustments considered necessary for a fair presentation of the Company’s financial position and operating results. Operating results for the six months endedJune 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020 or any other period. These financial statements and notes should be read in conjunction with the financial statements for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission, or the SEC, on January 28, 2020 (File No. 001-33351), or the Company’s 2019 Form 10-K.

Revenues

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

Accounts receivable are recorded net of the allowance for doubtful accounts, which represents the Company’s best estimate of credit losses. Allowance for doubtful accounts was $70,000 as of June 30, 2020 and December 31, 2019.

Three customers accounted for 42% and one customer accounted for 20% of total revenues in the quarter and six months ended June 30, 2020, respectively. Two customers accounted for 31% and one customer accounted for 20% of total revenues in the quarter and six months ended June 30, 2019, respectively. Four customers accounted for 89% and two customers accounted for 62% of accounts receivable as of June 30, 2020 and December 31, 2019, respectively.

Collaboration income

Collaboration income is recognized within Other income when contractual performance obligations, outside the ordinary activities of the Company, have been satisfied and control has been transferred to a collaboration partner. Collaboration income for each performance obligation is based on the fair value of such performance obligation relative to the total fair value of all performance obligations multiplied by the overall transaction price. A deferred collaboration income liability is recorded when payments are received prior to satisfaction of performance obligations. A collaboration receivable is recorded when amounts are owed to the Company under the collaboration agreements and related support services. The Company recognized Collaboration income net of costs, within Other income in the Statement of Operations of zero and $1,381,818, for the quarters ended June 30, 2020 and 2019, respectively. The Company recognized Collaboration income net of costs, within Other income in the Statement of Operations of zero and $7,116,667, for the six months ended June 30, 2020 and 2019, respectively.

Stock-based Compensation

Total compensation cost related to non-vested awards not yet recognized at June 30, 2020 was $270,740. The total compensation costs are expected to be recognized over a weighted-average period of 0.5 years.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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.

8. Fair Value Measurements

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

9. Credit Facility and Paycheck Protection Program Loan

The Company's Loan and Security Agreement (the “Credit Facility”) with a bank expired April 30, 2020 and was not renewed. The Credit Facility had previously supported letters of credit in the amount of $226,731 issued in favor of the Company's landlords. These letters of credit remain outstanding and are secured by the Company's cash balances.

On April 28, 2020, the Company received a loan of $773,200 from a bank under the U.S. Small Business Administration (“SBA”) Paycheck Protection Program (the “PPP”) of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The Company planned to use the proceeds from the loan for covered payroll costs, rent and utilities in accordance with the relevant terms and conditions of the CARES Act. On May 6, 2020, following the issuance of new guidance from the SBA regarding specific eligibility requirements under the PPP, the Company initiated the immediate repayment of the full amount of the loan to the bank.

The settlement has been entered by the United States District Court for the District of Massachusetts.

Item 2. 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 financial statements and the accompanying notes to those financial statements included elsewhere in this Quarterly Report on Form 10-Q. 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 below section of this Quarterly Report on Form 10-Q titled “Cautionary Note Regarding Forward-Looking Statements.” Unless the context otherwise requires, all references to “we”, “us”, the “Company”, or “NeuroMetrix” in this Quarterly Report on Form 10-Q refer to NeuroMetrix, Inc.

Overview

NeuroMetrix develops and commercializes health care products that utilize non-invasive neurostimulation and digital medicine. Our core expertise in biomedical engineering has been refined over two decades of designing, building and marketing medical devices that stimulate nerves and analyze nerve response for diagnostic and therapeutic purposes. We created the market for point-of-care nerve testing and were first to market with sophisticated wearable technology for symptomatic relief of chronic pain. Our business is fully integrated with in-house capabilities spanning research and development, manufacturing, regulatory affairs and compliance, sales and marketing, product fulfillment and customer support. We derive revenues from the sale of medical devices and after-market consumable products and accessories. Our products are sold in the United States and select overseas markets. They are cleared by the U.S. Food and Drug Administration (FDA) and regulators in foreign jurisdictions where appropriate. We have two principal product lines:

•Point-of-care neuropathy diagnostic tests

•Wearable neurostimulation devices

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

Early detection of DPN is important because there are no treatment options once the nerves have degenerated. Today’s diagnostic methods for DPN range from a simple monofilament test for lack of sensory perception in the feet to a nerve conduction study performed by a specialist. Our DPNCheck technology provides a rapid, low cost, quantitative test for peripheral nerve disease, including DPN. It addresses an important medical need and is particularly effective in screening large populations. DPNCheck has been validated in numerous clinical studies. We anticipated DPNCheck revenue growth in 2020; however, the effects of the COVID-19 pandemic on DPNCheck revenues are not yet capable of a clear assessment. We are investing R&D resources in the next generation technology to enhance the user experience, improve manufacturing, and restrict the potential use of non-compliant biosensors. Release of the new DPNCheck, forecast for late 2020 or early 2021, may also provide the opportunity for customer upgrades and expansion of product margins.

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

Chronic pain affects over 100 million adults in the United States and more than 1.5 billion people worldwide. The estimated incremental impact of chronic pain on health care costs in the United States is over $250 billion per year and lost productivity is estimated to exceed $300 billion per year. The most common approach to chronic pain management is pain medication. This includes over-the-counter (OTC) internal and external analgesics as well as prescription pain medications, both non-opioid and opioid. The approach to treatment is individualized, drug combinations may be employed, and the results are often inadequate. Side effects, including the potential for addiction, are substantial. Increasingly, restrictions are being imposed on access to prescription opioids. Reflecting the complexity of chronic pain and the difficulty in treating it, we believe that inadequate relief leads 25% to 50% of pain sufferers to seek alternatives to prescription pain medications. These alternatives include nutraceuticals, acupuncture, chiropractic care, non-prescription analgesics, electrical stimulators, braces, sleeves, pads and other items. In total, these pain relief products and services account for approximately $20 billion in annual out-of-pocket spending in the United States.

Nerve stimulation is a long-established category of treatment for chronic pain. This treatment approach is available through implantable spinal cord stimulation requiring surgery with its attendant risks. Non-invasive approaches involving transcutaneous electrical nerve stimulation (TENS) have achieved limited efficacy in practice due to device limitations, ineffective dosing and low patient adherence.

Quell, our app-enabled wearable technology for chronic pain, is designed to address many TENS limitations. Over the past year we have restructured the Quell commercial model to achieve a positive net operating contribution after direct costs. Success in our continued efforts should position us to crossover to a net positive contribution during 2020. Most of our sales are direct-to-consumer via our e-commerce platform, www.QuellRelief.com.

When we are confident that we have secured this core commercial model, including efficient ad spending, our objective will turn to growth. This could encompass greater ad promotion in order to more rapidly expand the Quell user population, and it could include additional applications for the technology and, potentially, other markets.

Our GlaxoSmithKline (GSK) collaboration on Quell continues to be productive as we support GSK’s progress toward launch in markets outside the U.S. This collaboration was initiated in early 2018 and has delivered approximately $20.5 million to us in development milestones plus additional co-funded R&D.

Both DPNCheck and Quell are sophisticated neurotechnology products that are unique in their markets. Our goal for both products is the same: to optimize market positioning and financial performance for the benefit of our shareholders. It is possible that at a point in the future either of the product lines could be monetized, in whole or in part. For example, we may consider following the model we employed in selling to GSK rights to the Quell technology for markets outside the U.S.

Liquidity and Capital Resources

Our principal source of liquidity is cash and cash equivalents of $5.4 million at June 30, 2020. Funding for our operations largely depends on revenues from the sale of our commercial products. A low level of market interest in Quell or DPNCheck, a decline in our consumables sales, unanticipated increases in our operating costs, and the continuing effects of the COVID-19 pandemic could have an adverse effect on our liquidity and cash.

	June 30, 2020		December 31, 2019		Change		% Change
	(in thousands)
Cash and cash equivalents	$	5,435.0	$	3,126.2	$	2,308.8	73.9	%

During the six months endedJune 30, 2020, our cash and cash equivalents increased by $2.3 million reflecting net proceeds of $4.1 million from common stock sales under our ATM program partially offset by $1.8 million cash used in operating activities.

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

	Quarters Ended June 30,		Year Ended December 31,
	2020	2019	2019
Days sales outstanding (days)	26	33	27
Inventory turnover rate (times per year)	1.7	5.5	3.5

Days sales outstanding (DSO) reflect customer payment terms which vary from payment on order to 60 days from invoice date. DSO was reduced during the quarter ended June 30, 2020 due to increased collection and lower receivables with terms.

The inventory turnover rate of 1.7 in the second quarter of 2020 reflected lower sales due to the impact of COVID-19. The inventory turnover rate during the quarter ended June 30, 2019 of 5.5 includes the effects of a $1.9 million inventory provision recorded in that quarter. Excluding this provision, the turnover rate was 1.1 during the quarter ended June 30, 2019.

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

	Six Months Ended June 30,
	2020			2019
	(in thousands)
Net cash used in operating activities (excluding collaboration income)	$	(1,831.8	)	$	(6,582.4	)
Net cash provided by collaboration income	—			4,760.1
Net cash used in operating activities	(1,831.8		)	(1,822.3		)
Net cash used in investing activities	$	(10.5	)	—
Net cash provided by financing activities	4,151.0			—
Net cash (used) provided	$	2,308.7		$	(1,822.3	)

During the six months ended June 30, 2020, our operating activities consumed $1.8 million of cash offset by $4.2 million in net proceeds from sales of common stock.

We have reported recurring losses from operations and negative cash flows from operating activities. These factors raise substantial doubt about our ability to continue as a going concern for the one-year period from the date of issuance of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. We held cash and cash equivalents of $5.4 million as of June 30, 2020. We believe that these resources and the cash to be generated from future product sales will be sufficient to meet our projected operating requirements into the third quarter of 2021. Accordingly, we will need to raise additional funds to support our operating and capital needs in the third quarter of 2021 and beyond.

We continue to face significant challenges and uncertainties. Among these uncertainties is the future effect on the Company's business of the COVID-19 pandemic which, in late first quarter of 2020 and throughout the second quarter of 2020, depressed sales of the Company's products. As a result, our available capital resources may be consumed more rapidly than currently expected due to (a) decreases in sales of our products, including decreases in customer orders related to the COVID-19 pandemic, and the uncertainty of future revenues from new products; (b) the effect of the COVID-19 pandemic on our ability to obtain parts and materials from our suppliers while continuing to staff critical production and fulfillment functions, (c) changes we may make to the business that affect ongoing operating expenses; (d) changes we may make in our business strategy; (e) regulatory developments affecting our existing products; (f) changes we may make in our research and development spending plans; and (g) other items affecting our forecasted level of expenditures and use of cash resources. We may attempt to obtain additional funding through public or private financing, collaborative arrangements with strategic partners, or through additional credit lines or other debt financing sources. However, we may not be able to secure such funding in a timely manner or on favorable terms, if at all. We filed a shelf registration statement on Form S-3 with the SEC covering shares of our common stock and other securities for sale, giving us the opportunity to raise funding when needed or otherwise considered appropriate at prices and on terms to be determined at the time of any such offerings. Pursuant to the instructions to Form S-3, we have the ability to sell shares under the shelf registration statement, during any 12-month period, in an amount less than or equal to one-third of the aggregate market value of our common stock held by non-affiliates. If we raise additional funds by issuing equity or debt securities, either through the sale of securities pursuant to a registration statement or by other means, our existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of our existing stockholders. If we raise additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to our potential products or proprietary technologies, or grant licenses on terms that are not favorable to us. Without additional funds, we may be forced to delay, scale back or eliminate some of our sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue our operations. If any of these events occurs, our ability to achieve our development and commercialization goals would be adversely affected. 

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

As of June 30, 2020, we did not have any off-balance sheet financing arrangements.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 required that lessees recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. We adopted ASU 2016-02, using the modified retrospective method, upon its effective date of January 1, 2019. The impact of adoption was an increase to long-term assets and total liabilities of approximately $1.9 million as of January 1, 2019.

Cautionary Note Regarding Forward-Looking Statements

The statements contained in this Quarterly Report on Form 10-Q, including under the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other sections of this Quarterly Report, include forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, including, without limitation, statements regarding our or our management’s expectations, hopes, beliefs, intentions or strategies regarding the future, such as our estimates regarding anticipated operating losses, future revenues and projected expenses, the effect of the COVID-19 pandemic on our operating capabilities, our future liquidity and our expectations regarding our needs for and ability to raise additional capital; our ability to manage our expenses effectively and raise the funds needed to continue our business; our belief that there are unmet needs for the management of chronic pain and in the diagnosis and treatment of diabetic neuropathy; our expectations surrounding Quell and DPNCheck; our expected timing and our plans to develop and commercialize our products; our ability to meet our proposed timelines for the commercial availability of our products; our ability to obtain and maintain regulatory approval of our existing products and any future products we may develop; regulatory and legislative developments in the United States and foreign countries; the performance of our third-party manufacturers; our ability to obtain and maintain intellectual property protection for our products; the successful development of our sales and marketing capabilities; the size and growth of the potential markets for our products and our ability to serve those markets; our estimate of our customer returns of our products; the rate and degree of market acceptance of any future products; our reliance on key scientific management or personnel; the payment and reimbursement methods used by private or government third party payers; and other factors discussed elsewhere in this Quarterly Report on Form 10-Q. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “plan” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. The forward-looking statements contained in this quarterly report are based on our current expectations and beliefs concerning future developments and their potential effects on us. There can be no assurance that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those factors described in the section titled “Risk Factors” in our Annual Report on Form 10-K. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

Item 3. 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 4. 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 June 30, 2020, 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)Changes in Internal Controls. There were no changes in our internal control over financial reporting, identified in connection with the evaluation of such internal control that occurred during the quarter ended June 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

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

Item 1A. Risk Factors

There have been no material changes in the risk factors described in “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2019 other than the updated risk factors noted below.

Our financial condition and results of operations could be adversely affected by the ongoing coronavirus outbreak.

Any outbreak of contagious diseases, such as COVID-19, or other adverse public health developments, could have a material and adverse effect on our business operations. Such adverse effects could include disruptions or restrictions on the ability of our customers, distributors and suppliers to maintain normal business activities. It could also affect the ability of our personnel to perform their normal responsibilities and could result in temporary closures of our facilities. Beginning in the first quarter of 2020, our volume of product orders has been adversely impacted by COVID-19, which has had an adverse effect on our revenues.

As COVID-19 continues to affect individuals and businesses around the globe, we will likely continue to experience disruptions that could severely impact our business, including:

• restrictions on the conduct of our business imposed by governmental regulators;

• diversion or prioritization of healthcare resources away from diagnostic testing which uses our medical devices by physician clinics, hospitals, home testing services and other healthcare providers;

• supply chain disruption, including delays in fulfillment or cancellations of purchase orders by our parts and services suppliers which would hamper our manufacturing capabilities;

• limitations on employee resources that would otherwise be focused on our business activities, including because of sickness of employees or their families or requirements imposed on employees to avoid contact with large groups of people; and

• disruption in our distribution channels, including shipping providers and distributors.

Our results of operations could continue to be adversely affected to the extent that COVID-19 or any other epidemic harms our business or the economy in general either domestically or in any other region in which we do business. The extent to which COVID-19 affects our operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak, new information that may emerge concerning the severity of COVID-19 and the actions to contain COVID-19 or treat its impact, among others, which could have an adverse effect on our business and financial condition.

Item 3.    Defaults Upon Senior Securities

Business and Basis of Presentation

Our Business-An Overview

NeuroMetrix, Inc., or the Company, is a leading developer and manufacturer of diagnostic and therapeutic neurostimulation based medical devices that are used throughout the world. The Company has three FDA cleared commercial products. DPNCheck® is a point-of-care test that is used to evaluate peripheral neuropathies. ADVANCE^™ is a point-of-care device that provides nerve conduction studies as an aid in diagnosing and evaluating patients suspected of having focal or systemic neuropathies. Quell^® 2.0 is a wearable, mobile app enabled, neurostimulation device indicated for symptomatic relief and management of chronic pain and is available OTC. The Company maintains an active, industry-leading R&D program.

The accompanying financial statements have been prepared on a basis which assumes that the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business. The Company has reported recurring losses from operations and negative cash flows from operating activities. At June 30, 2020, the Company had an accumulated deficit of $196.3 million. These factors raise substantial doubt about the Company’s ability to continue as a going concern for the one-year period from the date of issuance of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company held cash and cash equivalents of $5.4 million as of June 30, 2020. The Company believes that these resources and the cash to be generated from future product sales will be sufficient to meet its projected operating requirements into the third quarter of 2021. Accordingly, the Company will need to raise additional funds to support its operating and capital needs in the third quarter of 2021 and beyond.

The Company continues to face significant challenges and uncertainties. Among these uncertainties is the future effect on the Company's business of the COVID-19 pandemic which, in late first quarter of 2020 and throughout the second quarter of 2020, depressed sales of the Company's products. 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, including decreases in customer orders related to the COVID-19 pandemic, and the uncertainty of future revenues from new products; (b) the effect of the COVID-19 pandemic on the Company's ability to obtain parts and materials from the Company's suppliers while continuing to staff critical production and fulfillment functions; (c) changes the Company may make to the business that affect ongoing operating expenses; (d) changes the Company may make in its business strategy; (e) regulatory developments affecting the Company’s existing products; (f) changes the Company may make in its research and development spending plans; and (g) other items affecting the Company’s forecasted level of expenditures and use of cash resources.

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 funding 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.

Unaudited Interim Financial Statements

The accompanying unaudited balance sheet as of June 30, 2020, unaudited statements of operations, changes in stockholders' equity and cash flows for the quarters and six months ended June 30, 2020 and 2019 have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. The accompanying balance sheet as of December 31, 2019 has been derived from audited financial statements prepared at that date, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the financial statements include all normal and recurring adjustments considered necessary for a fair presentation of the Company’s financial position and operating results. Operating results for the six months endedJune 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020 or any other period. These financial statements and notes should be read in conjunction with the financial statements for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission, or the SEC, on January 28, 2020 (File No. 001-33351), or the Company’s 2019 Form 10-K.

Revenues

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

Accounts receivable are recorded net of the allowance for doubtful accounts, which represents the Company’s best estimate of credit losses. Allowance for doubtful accounts was $70,000 as of June 30, 2020 and December 31, 2019.

Three customers accounted for 42% and one customer accounted for 20% of total revenues in the quarter and six months ended June 30, 2020, respectively. Two customers accounted for 31% and one customer accounted for 20% of total revenues in the quarter and six months ended June 30, 2019, respectively. Four customers accounted for 89% and two customers accounted for 62% of accounts receivable as of June 30, 2020 and December 31, 2019, respectively.

Collaboration income

Collaboration income is recognized within Other income when contractual performance obligations, outside the ordinary activities of the Company, have been satisfied and control has been transferred to a collaboration partner. Collaboration income for each performance obligation is based on the fair value of such performance obligation relative to the total fair value of all performance obligations multiplied by the overall transaction price. A deferred collaboration income liability is recorded when payments are received prior to satisfaction of performance obligations. A collaboration receivable is recorded when amounts are owed to the Company under the collaboration agreements and related support services. The Company recognized Collaboration income net of costs, within Other income in the Statement of Operations of zero and $1,381,818, for the quarters ended June 30, 2020 and 2019, respectively. The Company recognized Collaboration income net of costs, within Other income in the Statement of Operations of zero and $7,116,667, for the six months ended June 30, 2020 and 2019, respectively.

Stock-based Compensation

Total compensation cost related to non-vested awards not yet recognized at June 30, 2020 was $270,740. The total compensation costs are expected to be recognized over a weighted-average period of 0.5 years.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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.

Fair Value Measurements

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

Unaudited Interim Financial Statements

Unaudited Interim Financial Statements

The accompanying unaudited balance sheet as of June 30, 2020, unaudited statements of operations, changes in stockholders' equity and cash flows for the quarters and six months ended June 30, 2020 and 2019 have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. The accompanying balance sheet as of December 31, 2019 has been derived from audited financial statements prepared at that date, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the financial statements include all normal and recurring adjustments considered necessary for a fair presentation of the Company’s financial position and operating results. Operating results for the six months endedJune 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020 or any other period. These financial statements and notes should be read in conjunction with the financial statements for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission, or the SEC, on January 28, 2020 (File No. 001-33351), or the Company’s 2019 Form 10-K.

Revenues

Revenues

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

Accounts receivable are recorded net of the allowance for doubtful accounts, which represents the Company’s best estimate of credit losses. Allowance for doubtful accounts was $70,000 as of June 30, 2020 and December 31, 2019.

Three customers accounted for 42% and one customer accounted for 20% of total revenues in the quarter and six months ended June 30, 2020, respectively. Two customers accounted for 31% and one customer accounted for 20% of total revenues in the quarter and six months ended June 30, 2019, respectively. Four customers accounted for 89% and two customers accounted for 62% of accounts receivable as of June 30, 2020 and December 31, 2019, respectively.

Collaboration income

Collaboration income is recognized within Other income when contractual performance obligations, outside the ordinary activities of the Company, have been satisfied and control has been transferred to a collaboration partner. Collaboration income for each performance obligation is based on the fair value of such performance obligation relative to the total fair value of all performance obligations multiplied by the overall transaction price. A deferred collaboration income liability is recorded when payments are received prior to satisfaction of performance obligations. A collaboration receivable is recorded when amounts are owed to the Company under the collaboration agreements and related support services. The Company recognized Collaboration income net of costs, within Other income in the Statement of Operations of zero and $1,381,818, for the quarters ended June 30, 2020 and 2019, respectively. The Company recognized Collaboration income net of costs, within Other income in the Statement of Operations of zero and $7,116,667, for the six months ended June 30, 2020 and 2019, respectively.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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.
