PROSPECTUS SUMMARY

The following summary highlights selected information contained elsewhere in or incorporated by reference in this prospectus. This summary is not complete and does not contain all of the information that should be considered before investing in our Securities. Potential investors should read the entire prospectus carefully, including the more detailed information regarding our business provided in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (the “Form 10-K”) incorporated herein by reference, the risks of purchasing our Securities discussed under the “Risk Factors” section of the Form 10-K, and our financial statements and the accompanying notes to the financial statements incorporated herein by reference.

Our Company

We are leveraging experience with pre-clinical enhanced ultrasound devices to develop technology for increasing the capabilities of clinical diagnostic ultrasound, to broaden patient access to the safe diagnosis and treatment of a number of significant medical conditions in circumstances where expensive X-ray computed tomography (“CT”) and magnetic resonance imaging (“MRI”) technology is unavailable or impractical.

In 2010, we began marketing and selling our Nexus 128 system, which combined light-based thermoacoustics and ultrasound to address the imaging needs of researchers studying disease models in pre-clinical applications. Building on this expertise in thermoacoustics, we have developed a next-generation technology platform — Thermo Acoustic Enhanced Ultrasound, or TAEUS — which is intended to enhance the capability of clinical ultrasound technology and support the diagnosis and treatment of a number of significant medical conditions that currently require the use of expensive CT or MRI imaging or where imaging is not practical using existing technology.

We ceased production of our Nexus 128 system as of January 1, 2019 and stopped providing service support and parts for all existing Nexus 128 systems as of July 1, 2019 in order to focus our resources on the development of our TAEUS technology.

Image below: An illustration of a typical cart-based ultrasound system (left) with ENDRA’s first-generation technology (right).

Unlike the near-infrared light pulses used in our legacy Nexus 128 system, our TAEUS technology uses radio frequency, or RF, pulses to stimulate tissues, using a small fraction (less than 1%) of the energy that would be transmitted into the body during an MRI scan. The use of RF energy allows our TAEUS technology to penetrate deep into tissue, enabling the imaging of human anatomy at depths equivalent to those of conventional ultrasound. The RF pulses are absorbed by tissue and converted into ultrasound signals, which are detected by an external ultrasound receiver and a digital acquisition system that is part of the TAEUS system. The detected ultrasound is processed into images using our proprietary algorithms and displayed to complement conventional gray-scale ultrasound images. The TAEUS imaging process is illustrated below:

We believe that our TAEUS technology has the potential to add a number of new capabilities to conventional ultrasound and thereby enhance the utility of both existing and new ultrasound systems and extend the use of ultrasound technology to circumstances that either require the use of expensive CT or MRI imaging systems or where imaging is not practical using existing technology.

Our TAEUS platform is not intended to replace CT or MRI systems, both of which are versatile imaging technologies with capabilities and uses beyond the focus of our business. However, they are also expensive, with a CT system costing approximately $1 million and an MRI system costing up to $3 million. In addition, and in contrast to ultrasound systems, due to their limited number and the fact that they are usually fixed-in-place at major medical facilities, CT or MRI systems are frequently inaccessible to patients.

2

To demonstrate the capabilities of our TAEUS platform, we have conducted various internal ex-vivo laboratory experiments and limited internal in-vivo large animal studies. In our ex-vivo and in-vivo testing, we have demonstrated that the TAEUS platform has the following capabilities and potential clinical applications:

●

Tissue Composition: Our TAEUS technology enables ultrasound to distinguish fat from lean tissue. This capability would enable the use of TAEUS-enhanced ultrasound for the early identification, staging and monitoring of NAFLD, a precursor to nonalcoholic steatohepatitis (“NASH”), liver fibrosis, cirrhosis and liver cancer.

●

Temperature Monitoring: Our TAEUS technology enables traditional ultrasound to visualize changes in tissue temperature, in real time. This capability would enable the use of TAEUS-enhanced ultrasound to guide thermoablative therapy, which uses heat or cold to remove tissue, such as in the treatment of cardiac atrial fibrillation, or removal of cancerous liver and kidney lesions, with greater accuracy.

●

Vascular Imaging: Our TAEUS technology enables ultrasound to view blood vessels from any angle, using only a saline solution contrasting agent, unlike Doppler ultrasound, which requires precise viewing angles. This capability would enable the use of TAEUS-enhanced ultrasound to easily identify arterial plaque or malformed vessels.

●

Tissue Perfusion: Our TAEUS technology enables ultrasound to image blood flow at the capillary level in a region, organ or tissue. This capability could be used to assist physicians in characterizing microvasculature fluid flows symptomatic of damaged tissue, such as internal bleeding from trauma, or diseased tissue, such as certain cancers.

To further test the capability of our TAEUS platform to distinguish tissue composition in conjunction with an NAFLD application, we engaged the Centre for Imaging Technology Commercialization (“CIMTEC”), a contract research organization, to initiate human studies. In October 2018, we received an Investigational Testing Authorization from Health Canada to commence the first human studies with our TAEUS clinical system targeting NAFLD, guiding our algorithm development, and comparing our technology to MRI. The feasibility study, the first of several planned human studies, is being conducted in collaboration with Robarts Research Institute in London, Canada. We reported our completion of this study on September 26, 2019. The data collected from the study, including additional usability inputs, was included in our TAEUS liver device technical file submission for device CE Mark, which we submitted in December 2019.

Ultrasound systems are more broadly available to patients than either CT or MRI systems. There are an estimated one million ultrasound systems globally in use today generating over 400 million annual diagnostic ultrasound procedures. Sales of ultrasound diagnostic equipment were approximately $4.4 billion globally in 2017 and an estimated 30,000 to 50,000 new and replacement ultrasound systems are sold into the market annually. Ultrasound systems are relatively inexpensive compared to CT and MRI systems, with smaller portable ultrasound systems costing as little as $10,000 and new cart-based ultrasound systems costing between $75,000 and $200,000. These numbers cover all types of diagnostic ultrasound procedures, including systems intended for cardiology, prenatal and abdominal use. However, we do not intend to address low-cost, portable ultrasound systems and systems focused on applications, such as prenatal care, where we believe our TAEUS technology will not substantially impact patient care. Accordingly, we define our addressable market for one or more of our TAEUS applications at approximately 365,000 cart-based ultrasound systems currently in use throughout the world.

Many ultrasound systems are designed to be moved by an operator from room to room, or closer to patients. CT and MRI systems are stationary systems, requiring the patient to travel to a medical center; there are only about 32,000 CT systems and 16,000 MRI systems located in the United States. Ultrasound technology does not present the same safety concerns as CT and MRI technology, since ultrasound does not emit ionizing radiation and ultrasound contrast agents are considered to be generally safe. The ultrasound’s imaging capabilities, however, are more limited compared to CT and MRI technologies, which are able to measure tissue temperature during thermal ablation surgery or quantify fat to diagnose early stage liver disease.

After approval, our TAEUS technology can be added as an accessory to existing ultrasound systems, helping to improve clinical decision-making on the front lines of patient care, without requiring new clinical workflows or large capital investments. We are also developing TAEUS for incorporation into new ultrasound systems, primarily through our collaboration with GE Healthcare, described more fully below.

3

Because of the large number of traditional ultrasound systems currently in global use, we are first developing our TAEUS technology for sale as an aftermarket accessory that works with existing ultrasound systems. Because our TAEUS technology is designed to enhance the utility of, not replace, conventional ultrasound, we believe healthcare providers will be able to increase the utilization of, and generate new revenue from, their existing ultrasound systems once we obtain required regulatory approval for specific applications. Based on our design work and our understanding of the ultrasound accessory market, we intend to price our initial NAFLD TAEUS application at a price point approximating $50,000, which may enable purchasers to recoup their investment by performing a relatively small number of additional ultrasound procedures. We further believe that clinicians will be attracted to our technology because it will enable them to perform more procedures with existing ultrasound equipment, thereby retaining more imaging patients in their clinics rather than referring patients out to a regional medical center for a CT or MRI scan.

Each of our TAEUS platform applications will require regulatory approvals before we are able to sell or license the application. Based on certain factors, such as the installed base of ultrasound systems, availability of other imaging technologies, such as CT and MRI, economic strength and applicable regulatory requirements, we intend to seek initial approval of our applications for sale in the European Union, followed by the United States and China.

The first TAEUS application we intend to commercialize is our NAFLD TAEUS application. Our initial target market for this application is the European Union. We believe that our NAFLD TAEUS application will qualify for sale in the European Union as a Class IIa medical device. As a result, we will be required to obtain a CE mark for our NAFLD TAEUS application before we can sell the application in the European Union. To this end, we have contracted with medical device contract engineering firms to perform the commercial product engineering for our NAFLD TAEUS application. Existing regulations would not require us to conduct a clinical trial to obtain a CE mark for this application. Nonetheless, for commercial reasons and to support our CE mark application we have contracted CIMTEC to conduct human studies to demonstrate our NAFLD TAEUS application’s ability to distinguish fat from lean tissue. In December 2019, we submitted a technical file for a CE mark for our TAEUS liver device.

While we are seeking a CE mark for our NAFLD TAEUS application, we are also preparing to expand our sales, marketing and customer support capabilities, so that we can commence initial sales of the application in the European Union once we have received this regulatory approval. Following receipt of such CE mark and placement of initial systems with researchers and universities, we plan to conduct one or more clinical studies to further demonstrate this product’s capabilities.

Simultaneously with the process of obtaining a CE mark for our NAFLD TAEUS application, we intend to prepare for submission to the U.S. Food and Drug Administration, or the FDA, an application under the Food, Drug and Cosmetic Act, or the FD&C Act, to sell our NAFLD TAEUS application in the U.S. We anticipate that the application, as well as those for our other TAEUS applications, will be submitted for approval under Section 510(k) of the FD&C Act. We expect that our initial FDA clearance will allow us to sell the NAFLD TAEUS application in the U.S. with general imaging claims. However, we will need to obtain additional FDA clearances to be able to make diagnostic claims for fatty tissue content determination. Accordingly, to support our commercialization efforts we expect that, following receipt of our initial FDA clearance, we will submit one or more additional applications to the FDA, each of which will need to include additional clinical trial data, so that following receipt of the necessary clearances we may make those diagnostic claims.

Collaboration with GE Healthcare

In April 2016, we entered into a Collaborative Research Agreement with General Electric Company, acting through its GE Healthcare business unit and the GE Global Research Center, or GE Healthcare. Under the terms of the agreement, GE Healthcare has agreed to assist us in our efforts to commercialize our TAEUS technology for use in a fatty liver application by, among other things, providing equipment and technical advice, and facilitating introductions to GE Healthcare clinical ultrasound customers. In return for this assistance, we have agreed to afford GE Healthcare certain rights of first offer with respect to manufacturing and licensing rights for the target application. More specifically, we have agreed that, prior to commercially releasing our NAFLD TAEUS application, we will offer to negotiate an exclusive ultrasound manufacturer relationship with GE Healthcare for a period of at least one year of commercial sales. The commercial sales would involve, within our sole discretion, either our Company commercially selling GE Healthcare ultrasound systems as the exclusive ultrasound system with our TAEUS fatty liver application embedded, or GE Healthcare being the exclusive ultrasound manufacturer to sell ultrasound systems with our TAEUS fatty liver application embedded. The agreement is subject to termination by either party upon not less than 60 days’ notice.

On January 13, 2020, we and GE Healthcare entered into an amendment to our agreement, extending its term to January 14, 2021 and modifying certain rights of first offer held by GE Healthcare. We are in discussions with GE Healthcare regarding further extending this term.

Recent Developments

Private Placement of Series A Preferred Stock, Common Stock and Warrants

On December 11, 2019, we closed the First Private Placement, in which we sold 6,338.49 shares of its Series A Preferred Stock and 0.9 million shares of Common Stock, along with Series A Warrants exercisable for an aggregate of 8.2 million shares of Common Stock, to accredited investors (the “Series A Investors”) for approximately $7.9 million of gross proceeds. The First Private Placement was made pursuant to a Securities Purchase Agreement (the “Series A Purchase Agreement”), dated as of December 5, 2019. The closing consisted of (i) the issuance of 5,809.09 shares of Series A Preferred Stock, approximately 0.8 million shares of Common Stock and Series A Warrants exercisable for an aggregate of approximately 7.5 million shares of Common Stock to Series A Investors party to the Series A Purchase Agreement as of December 5, 2019 and (ii) the issuance of 529.40 shares of Series A Preferred Stock, approximately 0.1 million shares of Common Stock and Series A Warrants exercisable for an aggregate of approximately 0.7 million shares of Common Stock to Investors who joined as parties to the Series A Purchase Agreement as of December 10, 2019. Pursuant to the Series A Purchase Agreement, each Investor elected whether to receive shares of Series A Preferred Stock or shares of Common Stock in the First Private Placement. We used a portion of the net proceeds from the First Private Placement to repay certain outstanding convertible notes due April 2020 and plan to use remaining net proceeds for working capital and general corporate purposes.

In connection with the closing of the First Private Placement, we filed a Certificate of Designations of Series A Convertible Preferred Stock (the “Series A Certificate of Designations”) with the Secretary of State of the State of Delaware setting forth the rights and preferences of the Series A Preferred Stock. Each share of Series A Preferred Stock has a $1,000 issue price (the “Series A Issue Price”). Dividends accrue on the Series A Issue Price at a rate of 6.0% per annum and are payable to holders of Series A Preferred Stock as, when and if declared by our Board of Directors. Shares of Series A Preferred Stock, including accrued but unpaid dividends, are convertible into Common Stock at a conversion price of $0.87 per share of Common Stock. The conversion price is subject to proportional adjustment for certain transactions relating to our capital stock, including stock splits, stock dividends and similar transactions. Holders of Series A Preferred Stock are entitled to a liquidation preference in the event of any liquidation, dissolution or winding up of the Company based on their shares’ aggregate Series A Issue Price and accrued and unpaid dividends. Holders may convert their shares of Series A Preferred Stock into Common Stock at any time and we have the right to cause each holder to convert their shares of Series A Preferred Stock in the event that (i) the average of the daily volume-weighted average price of Common Stock over any 10 consecutive trading days is greater than $1.74 (as adjusted for stock splits, stock dividends and similar transactions) and (ii) there is then an effective registration statement registering under the Securities Act of 1933, as amended (the “Securities Act”), the resale of the shares of Common Stock issuable upon such conversion of Series A Preferred Stock (together, the “Series A Forced Conversion Conditions”). Holders of shares of Series A Preferred Stock vote with the holders of Common Stock and are entitled to a number of votes equal to the number of shares of Common Stock into which such holder’s shares of Series A Preferred Stock are then convertible.

Each Series A Warrant entitles the holder to purchase a share of Common Stock for an exercise price per share equal to $0.87. The Series A Warrants are exercisable commencing immediately upon issuance and expire on the date five years after the date of the closing of the First Private Placement (the “Series A Closing Date”), unless earlier terminated pursuant to the terms of the Series A Warrant. If, during the term of the Series A Warrants, the Series A Forced Conversion Conditions are met, we may deliver notice thereof to the holders of the Series A Warrants and, after a 30-day period following such notice, any unexercised Series A Warrants will be forfeited. The Series A Warrants provide for cashless exercise in the event there is no effective registration statement registering under the Securities Act the resale of the shares of Common Stock issuable upon exercise of such Series A Warrants.

The Series A Purchase Agreement includes customary representations, warranties and covenants. In connection with the First Private Placement, we paid to Lake Street, the placement agent, a commission of 8.0% of the gross proceeds from the First Private Placement, agreed to reimburse up to $35,000 of Lake Street’s expenses and issued to Lake Street and its designees warrants exercisable for 327,606 shares of Common Stock (the “Series A Placement Agent Warrant”). The terms of the Series A Placement Agent Warrant are the same as those of the Series A Warrants.

Pursuant to the Series A Purchase Agreement, the Company, the Investors and Lake Street entered into a registration rights agreement (the “Registration Rights Agreement”) pursuant to which we agreed to file a registration statement (the “Registration Statement”) within 30 days of the Series A Closing Date covering the resale of the shares of Common Stock issuable upon conversion of the Series A Preferred Stock, the shares of Common Stock issued at the closing of the First Private Placement, and the shares of Common Stock issuable upon exercise of the Series A Warrants and the Placement Agent Warrant (collectively, the “Series A Registrable Securities”). Pursuant to the Registration Rights Agreement, we have agreed to use our commercially reasonable efforts to cause the Registration Statement to become effective as soon as practicable after filing and to remain effective until the earlier of the date that (i) all of the Series A Registrable Securities have been sold or (ii) the Series A Registrable Securities may be sold without restriction by each holder pursuant to Rule 144 under the Securities Act.

Private Placement of Series B Preferred Stock and Warrants

On December 23, 2019, we closed the Second Private Placement, in which we sold 351.711 shares of Series B Preferred Stock, along with Series B Warrants exercisable for an aggregate of 426,316 shares of Common Stock, to accredited investors (the “Series B Investors”) for approximately $405,000 of gross proceeds. The Second Private Placement was made pursuant to a Securities Purchase Agreement (the “Series B Purchase Agreement”), dated as of December 19, 2019. We plan to use the net proceeds from the Second Private Placement for working capital and general corporate purposes.

In connection with the closing of the Second Private Placement, we filed a Certificate of Designations of Series B Convertible Preferred Stock (the “Series B Certificate of Designations”) with the Secretary of State of the State of Delaware setting forth the rights and preferences of the Series B Preferred Stock. The Series B Preferred Stock has substantially the same rights and preferences as Series A Preferred Stock, except for a different conversion price and trading price of Common Stock at which the Series B Preferred Stock becomes subject to automatic conversion. Each share of Series B Preferred Stock has a $1,000 issue price (the “Series B Issue Price”). Dividends accrue on the Series B Issue Price at a rate of 6.0% per annum and are payable to holders of Series B Preferred Stock as, when and if declared by our Board of Directors. Shares of Series B Preferred Stock, including accrued but unpaid dividends, are convertible into Common Stock at a conversion price of $0.99 per share of Common Stock. The conversion price is subject to proportional adjustment for certain transactions relating to our capital stock, including stock splits, stock dividends and similar transactions. Holders of Series B Preferred Stock are entitled to a liquidation preference in the event of any liquidation, dissolution or winding up of the Company based on their shares’ aggregate Series B Issue Price and accrued and unpaid dividends. Such liquidation preference of Series B Preferred Stock holders is on a pari passu basis with holders of Series A Preferred Stock. Holders may convert their shares of Series B Preferred Stock into Common Stock at any time and we have the right to cause each holder to convert their shares of Series B Preferred Stock in the event that (i) the average of the daily volume-weighted average price of Common Stock over any 10 consecutive trading days is greater than $1.98 (as adjusted for stock splits, stock dividends and similar transactions) and (ii) there is then an effective registration statement registering under the Securities Act the resale of the shares of Common Stock issuable upon such conversion of Series B Preferred Stock (together, the “Series B Forced Conversion Conditions”). Holders of shares of Series B Preferred Stock vote with the holders of Common Stock, and with any other shares of preferred stock that vote with the Common Stock, and are entitled to a number of votes equal to the number of shares of Common Stock into which such holder’s shares of Series B Preferred Stock are then convertible.

Each Series B Warrant entitles the holder to purchase shares of Common Stock for an exercise price per share equal to $0.99. The Series B Warrants are exercisable commencing immediately upon issuance and expire on the date five years after the date of the closing of the Second Private Placement (the “Series B Closing Date”), unless earlier terminated pursuant to the terms of the Series B Warrant. If, during the term of the Series B Warrants, the Series B Forced Conversion Conditions are met, we may deliver notice thereof to the holders of the Series B Warrants and, after a 30-day period following such notice, any unexercised Series B Warrants will be forfeited. The Series B Warrants provide for cashless exercise in the event there is no effective registration statement registering under the Securities Act the resale of the shares of Common Stock issuable upon exercise of such Series B Warrants.

The Series B Purchase Agreement includes customary representations, warranties and covenants. In connection with the closing of the Second Private Placement, we paid to Lake Street, the placement agent, a commission of approximately 8.0% of the gross proceeds from the Second Private Placement and issued to Lake Street and its designees warrants exercisable for 14,211 shares of Common Stock (the “Series B Placement Agent Warrant”). The terms of the Series B Placement Agent Warrant are the same as those of the Series B Warrants.

Pursuant to the Series B Purchase Agreement, the Series B Investors became parties to the Registration Rights Agreement, pursuant to which we agreed to file the Registration Statement within 30 days of the Series A Closing Date covering the resale of the shares of Common Stock issuable upon conversion of the Series B Preferred Stock, the shares of Common Stock issuable upon exercise of the Series B Warrants and the Series B Placement Agent Warrant and the Series A Registrable Securities. The Registration Rights Agreement is summarized above in this “Recent Developments” section.

Risks Related to Our Business

An investment in our Securities involves a high degree of risk. You should carefully consider the risks summarized below. These risks are discussed more fully in the “Risk Factors” section of our Form 10-K incorporated herein by reference. These risks include, but are not limited to, the following:

●

We have a history of operating losses, and we may never achieve or maintain profitability.

●

Our efforts may never result in the successful development of commercial applications based on our TAEUS technology.

●

If we fail to obtain and maintain necessary regulatory clearances or approvals for our TAEUS applications, or if clearances or approvals for future applications and indications are delayed or not issued, our commercial operations will be harmed.

●

Our limited commercial experience makes it difficult to evaluate our current business, predict our future results or forecast our financial performance and growth.

●

We are depending on third parties to design, manufacture and seek regulatory approval of our TAEUS applications. If any third party fails to successfully design, manufacture and gain regulatory approval of our TAEUS applications, our business will be materially harmed.

●

Competition in the medical imaging market is intense and we may be unable to successfully compete.

●

If we are unable to secure additional financing on favorable terms, or at all, to meet our future capital needs, we will be unable to complete fully our current business plan.

●

We intend to market our TAEUS applications, if approved, globally, in which case we will be subject to the risks of doing business outside of the United States.

●

If we are unable to protect our intellectual property, then our financial condition, results of operations and the value of our technology and products could be adversely affected.

Implications of Being an Emerging Growth Company

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) and, for as long as we continue to be an “emerging growth company,” we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies,” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We could be an “emerging growth company” until December 31, 2022, or until the earliest of (i) the last day of the first fiscal year in which our annual gross revenues exceed $1.07 billion, (ii) the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which would occur if the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, or (iii) the date on which we have issued more than $1 billion in non-convertible debt during the preceding three-year period. We are choosing to “opt out” of the extended transition periods available under the JOBS Act for complying with new or revised accounting standards, but intend to take advantage of the other exemptions discussed above.

We are also currently considered a “smaller reporting company,” which generally means that we have a public float of less than $250 million. If we are still considered a “smaller reporting company” at such time as we cease to be an “emerging growth company,” we will be subject to increased disclosure requirements. However, the disclosure requirements will still be less than they would be if we were not considered either an “emerging growth company” or a “smaller reporting company.” Specifically, similar to “emerging growth companies,” “smaller reporting companies” are able to provide simplified executive compensation disclosures in their filings; are exempt from the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring that independent registered public accounting firms provide an attestation report on the effectiveness of internal control over financial reporting; and have certain other decreased disclosure obligations in their SEC filings, including, among other things, being required to provide only two years of audited financial statements in annual reports.

RISK FACTORS

An investment in the Securities involves a high degree of risk. You should carefully consider all of the information set forth in this prospectus and the documents incorporated by reference herein and, in particular, the risks set forth under the section captioned “Risk Factors” contained in our Form 10-K, before deciding to invest in the Securities. The risks and uncertainties we have described this prospectus and in any document incorporated herein are not the only ones we face, but are considered to be the most material.If additional risks and uncertainties that are not presently known to us or that we currently deem immaterial later materialize, then our business, prospects, results of operations and financial condition could be materially adversely affected. In that event, the trading price of our securities could decline, and you may lose all or part of your investment in our securities.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference contain “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, that are intended to be covered by the “safe harbor” created by those sections. Forward-looking statements, which are based on certain assumptions and describe our future plans, strategies and expectations, can generally be identified by the use of forward-looking terms such as “believe,” “expect,” “may,” “will,” “should,” “would,” “could,” “seek,” “intend,” “plan,” “goal,” “project,” “estimate,” “anticipate,” “strategy”, “future”, “likely” or other comparable terms and references to future periods. All statements other than statements of historical facts included in this prospectus and the documents incorporated by reference regarding our strategies, prospects, financial condition, operations, costs, plans and objectives are forward-looking statements. Examples of forward-looking statements include, among others, statements we make regarding expectations for revenues, cash flows and financial performance, the anticipated results of our development efforts and the timing for receipt of required regulatory approvals and product launches.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results and financial condition may differ materially from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the following:

●

our limited commercial experience, limited cash and history of losses;

●

our ability to obtain adequate financing to fund our business operations in the future;

●

our ability to achieve profitability;

●

our ability to develop a commercially feasible application based on our TAEUS technology;

●

market acceptance of our technology;

●

results of our human studies, which may be negative or inconclusive;

●

our ability to find and maintain development partners;

●

our reliance on collaborations and strategic alliances and licensing arrangements;

10

●

the amount and nature of competition in our industry;

●

our ability to protect our intellectual property;

●

potential changes in the healthcare industry or third-party reimbursement practices;

●

delays and changes in regulatory requirements, policy and guidelines including potential delays in submitting required regulatory applications for CE mark certification or FDA approval;

●

our ability to obtain CE mark certification and secure required FDA and other governmental approvals for our TAEUS applications;

●

our ability to maintain compliance with Nasdaq listing standards;

●

our ability to comply with regulation by various federal, state, local and foreign governmental agencies and to maintain necessary regulatory clearances or approvals; and

●

the other risks and uncertainties described in the Risk Factors section of our Form 10-K and in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section in our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2019.

Any forward-looking statement made by us in this prospectus is based only on information currently available to us and speaks only as of the date on which it is made. We undertake no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise. We anticipate that subsequent events and developments will cause our views to change. You should read this prospectus and the documents referenced in this prospectus and filed as exhibits to the registration statement, of which this prospectus is a part, completely and with the understanding that our actual future results may be materially different from what we expect. Our forward-looking statements do not reflect the potential impact of any future acquisitions, merger, dispositions, joint ventures or investments we may undertake. We qualify all of our forward-looking statements by these cautionary statements.

11

USE OF PROCEEDS

We will not receive any proceeds from the sale of Common Stock by the Selling Stockholders. To the extent we receive proceeds from the exercise of Series A Warrants and Series B Warrants held by the Selling Stockholders, we will use those proceeds for working capital and other general corporate purposes.

We have agreed to bear the expenses (other than selling commissions or any legal expenses incurred by any Selling Stockholder) in connection with the registration of the shares of our Common Stock being offered for resale hereunder by the Selling Stockholders.

See “Plan of Distribution” elsewhere in this prospectus for more information.

DETERMINATION OF OFFERING PRICE

The Selling Stockholders will determine at what price they may sell the offered Common Stock, and such sales may be made at prevailing market prices or at privately negotiated prices. See “Plan of Distribution” below for more information.

The Selling Stockholders identified in the table below may from time to time offer and sell under this prospectus any or all of the shares of Common Stock covered hereby described under the column “Shares of Common Stock Registered Hereby” in such table below.

Certain Selling Stockholders may be deemed to be “underwriters” as defined in the Securities Act. Any profits realized by such Selling Stockholders may be deemed to be underwriting discounts and commissions under the Securities Act.

The table below has been prepared based upon the information furnished to us by the Selling Stockholders and/or our transfer agent as of the date of this prospectus. The Selling Stockholders identified below may have converted, sold, transferred or otherwise disposed of some or all of their Series A Preferred Stock, Series A Warrants, Series B Preferred Stock, Series B Warrants or underlying Common Stock since the date on which the information in the following table is presented in transactions exempt from or not subject to the registration requirements of the Securities Act. Information concerning the Selling Stockholders may change from time to time and, if necessary, we will amend or supplement this prospectus accordingly. We cannot give an estimate as to the number of shares of Common Stock that will actually be held by the Selling Stockholders upon termination of this offering because the Selling Stockholders may offer some or all of their Common Stock, as applicable, under the offering contemplated by this prospectus or may acquire additional shares of Common Stock. The aggregate total number of shares of Common Stock that may be sold hereunder will not exceed the number of shares of Common Stock offered hereby. Please read the section entitled “Plan of Distribution” in this prospectus.

The following table sets forth the name of each Selling Stockholder, the number of shares of our Common Stock beneficially owned by such Selling Stockholder before this offering, the number of shares of Common Stock to be offered for such Selling Stockholder’s account and (if one percent or more) the percentage of Common Stock to be beneficially owned by such Selling Stockholder after completion of the offering. The number of shares of Common Stock owned are those beneficially owned, as determined under the rules of the SEC, and such information is not necessarily indicative of beneficial ownership for any other purpose. Under such rules, the Selling Stockholders’ beneficial ownership includes any shares of our Common Stock as to which a person has sole or shared voting power or dispositive power and any shares of Common Stock which the person has the right to acquire within 60 days after December 31, 2019 (as used in this section, the “Determination Date”), through the conversion or exercise of any option, warrant or right or other security (including upon the conversion of the Series A Preferred Stock and Series B Preferred Stock and exercise of the Series A Warrants and Series B Warrants), or pursuant to the automatic termination of a power of attorney or revocation of a trust, discretionary account or similar arrangement, and such shares are deemed to be beneficially owned and outstanding for computing the share ownership and percentage of the person holding such options, warrants or other rights, but are not deemed outstanding for computing the percentage of any other person. Except where we had knowledge of such ownership, the number presented in this column may not include shares held in street name or through other entities over which the Selling Stockholders have voting and dispositive power.

Unless otherwise set forth below, based upon information furnished to us by the Selling Stockholders, (a) the persons and entities named in the table have sole voting and sole dispositive power with respect to the shares set forth opposite the Selling Stockholder’s name, subject to community property laws, where applicable, (b) no Selling Stockholder had any position, office or other material relationship within the past three years with us or with any of our predecessors or affiliates, and (c) no Selling Stockholder is a broker-dealer or an affiliate of a broker-dealer. The number of shares of Common Stock shown as beneficially owned before the offering is based on information furnished to us or otherwise based on information available to us at the timing of the filing of the registration statement of which this prospectus forms a part.

PLAN OF DISTRIBUTION

The Selling Stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of Common Stock or interests in shares of Common Stock received after the date of this prospectus from a Selling Stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of Common Stock or interests in shares of Common Stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The Selling Stockholders may use any one or more of the following methods when disposing of shares or interests therein:

●

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

●

block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

●

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

●

an exchange distribution in accordance with the rules of the applicable exchange;

●

privately negotiated transactions;

●

short sales effected after the date the registration statement of which this prospectus is a part is declared effective by the SEC;

●

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

●

broker-dealers may agree with the Selling Stockholders to sell a specified number of such shares at a stipulated price per share;

●

a combination of any such methods of sale; and

●

any other method permitted by applicable law.

The Selling Stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of Selling Stockholders to include the pledgee, transferee or other successors in interest as Selling Stockholders under this prospectus. The Selling Stockholders also may transfer the shares of Common Stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

34

In connection with the sale of the Securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the Securities in the course of hedging the positions they assume. The Selling Stockholders may also sell shares of our Common Stock short and deliver the Securities to close out their short positions, or loan or pledge the Securities to broker-dealers that in turn may sell the Securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the Selling Stockholders from the sale of the Securities offered by them will be the purchase price of the Securities less discounts or commissions, if any. Each of the Selling Stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of Securities to be made directly or through agents. We will not receive any of the proceeds from this offering, although we will receive the exercise price of any exercised Series A Warrants or Series B Warrants paid to us by the Selling Stockholders or their transferees, which will be used for working capital and general corporate purposes.

The Selling Stockholders also may resell all or a portion of the Securities in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule.

The Selling Stockholders and any underwriters, broker-dealers or agents that participate in the sale of the Securities or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the Securities may be underwriting discounts and commissions under the Securities Act. Selling Stockholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the shares of our Common Stock to be sold, the names of the Selling Stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the Securities may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the Securities may not be sold unless they been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the Selling Stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of Securities in the market and to the activities of the Selling Stockholders and their affiliates. In addition, to the extent applicable, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the Selling Stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the Securities against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the Selling Stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the Securities offered by this prospectus.

We have agreed with the Selling Stockholders to use commercially reasonable efforts to keep the registration statement of which this prospectus is a part effective until the earlier of (1) such time as all of the Securities covered by this prospectus have been sold or (2) the date on which all of the Securities may be sold without restriction pursuant to Rule 144 of the Securities Act.

We have 60,000,000 shares of capital stock authorized under our Certificate of Incorporation, consisting of 50,000,000 shares of common stock with a par value of $0.0001 per share (“Common Stock”) and 10,000,000 shares of preferred stock with a par value of $0.0001 per share (“Preferred Stock”), of which 10,000 shares have been designated Series A Convertible Preferred Stock and 1,000 shares have been designated Series B Convertible Preferred Stock. As of December 31, 2019, we had 8,420,401 shares of Common Stock issued and outstanding held of record by 41 stockholders, 6,338.490 shares of Series A Preferred Stock issued and outstanding held of record by 144 stockholders and 351.712 shares of Series B Preferred Stock issued and outstanding held of record by seven stockholders. Our authorized but unissued shares of Common Stock and Preferred Stock are available for issuance without further action by our stockholders, unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded.

Common Stock

The holders of outstanding shares of Common Stock are entitled to such dividends as may be declared by our board of directors out of funds legally available for such purpose. The shares of Common Stock are neither redeemable nor convertible. Holders of Common Stock have no preemptive or subscription rights to purchase any of our securities.

Each holder of our Common Stock is entitled to one vote for each such share outstanding in the holder’s name. No holder of Common Stock is entitled to cumulate votes in voting for directors.

In the event of our liquidation, dissolution or winding up, the holders of our Common Stock are entitled to receive pro rata our assets, which are legally available for distribution, after payments of all debts and other liabilities. All of the outstanding shares of our Common Stock are fully paid and non-assessable.

Our shares of Common Stock are listed on the Nasdaq Capital Market under the symbol “NDRA.”

Preferred Stock

Our board of directors has the authority, without further action by the stockholders, to issue up to 10,000,000 shares of Preferred Stock in one or more series and to fix the designations, powers, rights, preferences, qualifications, limitations and restrictions thereof. These designations, powers, rights and preferences could include voting rights, dividend rights, dissolution rights, conversion rights, exchange rights, redemption rights, liquidation preferences, and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of Common Stock. The issuance of Preferred Stock could adversely affect the voting power of holders of Common Stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of Preferred Stock could have the effect of delaying, deferring or preventing change in our control or other corporate action.

Series A Convertible Preferred Stock. Each share of Series A Preferred Stock has a Series A Issue Price of $1,000. Dividends accrue on the Series A Issue Price at a rate of 6.0% per annum and are payable to holders of Series A Preferred Stock as, when and if declared by our Board of Directors.

36

Shares of Series A Preferred Stock, including accrued but unpaid dividends, are convertible into Common Stock at a conversion price of $0.87 per share of Common Stock. The conversion price is subject to proportional adjustment for certain transactions relating to our capital stock, including stock splits, stock dividends and similar transactions. Holders may convert their shares of Series A Preferred Stock into Common Stock at any time and we have the right to cause each holder to convert their shares of Series A Preferred Stock in the event that (i) the average of the daily volume-weighted average price of Common Stock over any 10 consecutive trading days is greater than $1.74 (as adjusted for stock splits, stock dividends and similar transactions) and (ii) there is then an effective registration statement registering under the Securities Act the resale of the shares of Common Stock issuable upon such conversion of Series A Preferred Stock.

Holders of Series A Preferred Stock are entitled to a liquidation preference in the event of any liquidation, dissolution or winding up of the Company based on their shares’ aggregate Series A Issue Price and accrued and unpaid dividends.

Holders of shares of Series A Preferred Stock vote with the holders of Common Stock and are entitled to a number of votes equal to the number of shares of Common Stock into which such holder’s shares of Series A Preferred Stock are then convertible.

Series B Convertible Preferred Stock. Each share of Series B Preferred Stock has a Series B Issue Price of $1,000. Dividends accrue on the Series B Issue Price at a rate of 6.0% per annum and are payable to holders of Series B Preferred Stock as, when and if declared by our Board of Directors.

Shares of Series B Preferred Stock, including accrued but unpaid dividends, are convertible into Common Stock at a conversion price of $0.99 per share of Common Stock. The conversion price is subject to proportional adjustment for certain transactions relating to our capital stock, including stock splits, stock dividends and similar transactions. Holders may convert their shares of Series B Preferred Stock into Common Stock at any time and we have the right to cause each holder to convert their shares of Series B Preferred Stock in the event that (i) the average of the daily volume-weighted average price of Common Stock over any 10 consecutive trading days is greater than $1.98 (as adjusted for stock splits, stock dividends and similar transactions) and (ii) there is then an effective registration statement registering under the Securities Act the resale of the shares of Common Stock issuable upon such conversion of Series B Preferred Stock.

Holders of Series B Preferred Stock are entitled to a liquidation preference in the event of any liquidation, dissolution or winding up of the Company based on their shares’ aggregate Series B Issue Price and accrued and unpaid dividends.  Such liquidation preference of Series B Preferred Stock holders is on a pari passu basis with holders of Series A Preferred Stock.

Holders of shares of Series B Preferred Stock vote with the holders of Common Stock, and with any other shares of preferred stock that vote with the Common Stock, and are entitled to a number of votes equal to the number of shares of Common Stock into which such holder’s shares of Series B Preferred Stock are then convertible.

Stock Options and Warrants

As of December 31, 2019, we had reserved the following shares of Common Stock for issuance pursuant to stock options, warrants and equity plans:

●

1,932,000 shares of Common Stock issuable upon the exercise of outstanding warrants issued in our initial public offering listed on the Nasdaq Capital Market under the symbol “NDRAW,” at an exercise price of $6.25 per share;

●

2,606,566 shares of Common Stock issuable upon the exercise of outstanding unregistered warrants, at a weighted average exercise price of $2.83 per share;

●

3,413,728 shares of our Common Stock issuable upon the exercise of outstanding stock options issued pursuant to our Incentive Plan at a weighted average exercise price of $1.80 per share; and

●

1,109,532 shares of our Common Stock reserved for future issuance under our Incentive Plan.

37

Other Convertible Securities

On July 26, 2019, we issued $2.59 million aggregate principal amount of 10.0% Senior Secured Convertible Notes due 2020 (the “Notes”) sold in a private placement.

Each Note bears interest at a rate of 10% per annum until maturity on April 26, 2020 (the “Maturity Date”). Interest will be paid in arrears on the outstanding principal amount on the three month anniversary of the issuance of the Notes and each three month period thereafter and on the Maturity Date.

Holders of Notes (“Noteholders”) are entitled to convert principal and accrued, unpaid interest on the Notes into shares of Common Stock. As of December 31, 2019, the Notes were convertible into 371,517 shares of Common Stock at a conversion price per share equal to $1.49 and we had additionally reserved an estimated 6,426 shares that may be issued in respect of accrued and unpaid interest upon conversion of such Notes.

The Notes provide for customary events of default. In the case of an event of default with respect to the Notes, each Noteholder may declare its Note to be due and payable immediately without further action or notice. If an event of default occurs and is continuing, interest on the Notes will automatically be increased to 18% until the default is cured.

GE Healthcare Right

In April 2016, we entered into a Collaborative Research Agreement with General Electric Company, acting through its GE Healthcare business unit and the GE Global Research Center, or GE Healthcare. The agreement provides that prior to selling any equity interests in our company to a healthcare device manufacturer, we will first offer to negotiate in good faith to sell such equity interests to GE Healthcare.

Anti-Takeover Effects of Certain Provisions of Delaware Law and Our Charter Documents

The following is a summary of certain provisions of Delaware law, our Certificate of Incorporation and our bylaws. This summary does not purport to be complete and is qualified in its entirety by reference to the corporate law of Delaware and our Certificate of Incorporation and bylaws.

Effect of Delaware Anti-Takeover Statute. We are subject to Section 203 of the Delaware General Corporation Law, an anti-takeover law. In general, Section 203 prohibits a Delaware corporation from engaging in any business combination (as defined below) with any interested stockholder (as defined below) for a period of three years following the date that the stockholder became an interested stockholder, unless:

●

prior to that date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

●

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares of voting stock outstanding (but not the voting stock owned by the interested stockholder) those shares owned by persons who are directors and officers and by excluding employee stock plans in which employee participants do not have the right to determine whether shares held subject to the plan will be tendered in a tender or exchange offer; or

●

on or subsequent to that date, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

38

Section 203 defines “business combination” to include the following:

●

any merger or consolidation involving the corporation and the interested stockholder;

●

any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;

●

subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

●

subject to limited exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or

●

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation, or who beneficially owns 15% or more of the outstanding voting stock of the corporation at any time within a three-year period immediately prior to the date of determining whether such person is an interested stockholder, and any entity or person affiliated with or controlling or controlled by any of these entities or persons.

Our Charter Documents. Our charter documents include provisions that may have the effect of discouraging, delaying or preventing a change in control or an unsolicited acquisition proposal that a stockholder might consider favorable, including a proposal that might result in the payment of a premium over the market price for the shares held by our stockholders. Certain of these provisions are summarized in the following paragraphs.

Effects of authorized but unissued common stock. One of the effects of the existence of authorized but unissued common stock may be to enable our board of directors to make more difficult or to discourage an attempt to obtain control of our Company by means of a merger, tender offer, proxy contest or otherwise, and thereby to protect the continuity of management. If, in the due exercise of its fiduciary obligations, the board of directors were to determine that a takeover proposal was not in our best interest, such shares could be issued by the board of directors without stockholder approval in one or more transactions that might prevent or render more difficult or costly the completion of the takeover transaction by diluting the voting or other rights of the proposed acquirer or insurgent stockholder group, by putting a substantial voting block in institutional or other hands that might undertake to support the position of the incumbent board of directors, by effecting an acquisition that might complicate or preclude the takeover, or otherwise.

Cumulative Voting. Our Certificate of Incorporation does not provide for cumulative voting in the election of directors, which would allow holders of less than a majority of the stock to elect some directors.

Vacancies. Our Certificate of Incorporation provides that all vacancies may be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum.

Special Meeting of Stockholders. A special meeting of stockholders may only be called by the Chairman of the board of directors, the President, the Chief Executive Officer, or the board of directors at any time and for any purpose or purposes as shall be stated in the notice of the meeting, or by request of the holders of record of at least 20% of the outstanding shares of common stock. This provision could prevent stockholders from calling a special meeting because, unless certain significant stockholders were to join with them, they might not obtain the percentage necessary to request the meeting. Therefore, stockholders holding less than 20% of the issued and outstanding common stock, without the assistance of management, may be unable to propose a vote on any transaction that would delay, defer or prevent a change of control, even if the transaction were in the best interests of our stockholders.
