THE COMPANY

Overview

enVVeno Medical Corporation is a medical device company focused on the advancement of innovative bioprosthetic (tissue-based) solutions to improve the standard of care for the treatment of venous disease. Chronic Venous Disease (“CVD”) is the world’s most prevalent chronic disease, impacting approximately 70% of the adult population of the U.S. Chronic Venous Insufficiency (“CVI”), is a large subset of CVD, which most often occurs when valves inside of the veins of the leg become damaged, resulting in the backwards flow of blood (reflux), blood pooling in the lower leg, increased pressure in the veins of the leg (venous hypertension) and in severe cases, venous ulcers that are difficult to heal. The Company is developing a replacement venous valve for patients suffering from severe CVI of the deep venous system of the leg.

The Company first developed the VenoValve®, which was a first-in-class surgical replacement venous valve (the Company received a not-approvable letter from the FDA in response to its PMA application for the VenoValve in August 2025). The Company is now focused on its next-generation, non-surgical venous valve product, called the enVVe® System. The enVVe System consists of the enVVe Valve, enVVe Delivery System, enVVe Nose Cone, the enVVe Delivery System Accessories, and the enVVe Crimping System. The enVVe Valve is a first-in-class, non-surgical, transcatheter based replacement venous valve being developed for the treatment of severe CVI. The enVVe Valve is designed to act as a one-way valve, to help assist in propelling blood up the veins of the leg, and back to the heart and lungs. The Company has completed pre-clinical testing on the enVVe System and has begun discussions with the U.S. Food and Drug Administration (“FDA”) regarding the enVVe pivotal trial.

enVVe is being developed for approval by the FDA. We cannot provide any assurance that enVVe will receive approval from the FDA (see the section entitled “Risk Factors” herein). There are currently no devices approved as surgical or non-surgical replacement venous valves, and there are currently no effective treatments for deep venous CVI caused by incompetent valves.

We develop and manufacture our products in a 14,507 sq. ft. leased manufacturing facility in Irvine, California, which has been ISO 13485-2016 certified for the design, development and manufacturing of tissue based implantable medical devices.

CVI Background

Chronic venous disease (“CVD”) is the world’s most prevalent chronic disease. CVD is clinically classified using a standardized system known as CEAP (clinical, etiological, anatomical, and pathophysiological). The CEAP system consists of seven clinical classifications (C0 to C6) with C4, C5 and C6 being the most severe categories of CVD.

Chronic Venous Insufficiency (“CVI”) is a large subset of CVD and is generally used to describe patients with C4 to C6 CVD. CVI is a debilitating condition that affects the venous system of the leg causing pain, swelling, edema, skin changes, and ulcerations.

The human leg contains three vein systems: the deep vein system, the superficial vein system, and the perforator vein system which connects the deep system to the superficial system. The deep venous system is located below the muscle and facia in the center portion of the leg and is responsible for approximately 90% of the blood flow. In order for blood to return to the heart from the foot, ankle, and lower leg, the calf muscle serves as a pump and pushes the blood up the veins of the leg against gravity and through a series of one-way valves. Each valve is supposed to open as blood passes through, and then close as blood progresses up the veins of the leg to the next valve. CVI occurs when the one-way valves in the veins of the leg fail and become incompetent. When the valves fail, gravity causes the blood to flow backwards and in the wrong direction (reflux). As blood pools in the lower leg, pressure inside the veins increases (venous hypertension). Reflux, and the resulting venous hypertension, causes the leg to swell, resulting in debilitating pain, and in the most severe cases, venous ulcers.

Severe CVI sufferers experience a significantly reduced quality of life. Daily activities such as preparing meals, housework, and personal hygiene (washing and bathing) become difficult due to reduced mobility. For many severe CVI sufferers, intense pain, which frequently occurs at night, prevents them from getting adequate sleep. Severe CVI sufferers are known to miss approximately 40% more workdays than the average worker. A high percentage of venous ulcer patients also experience severe itching, leg swelling, and an odorous discharge. Wound dressing changes, which occur several times a week, can be extremely painful. Venous ulcers from deep venous CVI are very difficult to heal, and a significant percentage of venous ulcers remain unhealed for more than a year. Even if healed, recurrence rates for venous ulcers are known to be high (20% to 40%) within the first year and as high as 60% after five years. Patients with severe CVI often become housebound and experience social isolation due to difficulty with ambulation. As a result, studies have shown that patients with active venous ulcers experience higher rates of anxiety and depression, with reported rates of anxiety of up to 30% and depression up to 40%. Rates of depression caused by venous ulcers among the elderly are even higher, with 48% of elderly venous ulcer patients having severe depressive symptoms.

We estimate that there are approximately 3.5 million patients with severe deep venous CVI in the U.S. including approximately 1.5 million patients that develop venous leg ulcers (C6 patients). The average patient seeking treatment of a venous ulcer spends as much as $30,000 a year on wound care, and the total direct medical costs from venous ulcer sufferers in the U.S. has been estimated to exceed $20 billion a year.

enVVe System

The enVVe System is designed to treat severe deep chronic venous insufficiency (“CVI”) through a minimally invasive, catheter-based approach. The procedure is performed without the need for open surgery or an overnight hospital stay. Built on the clinical foundation of the VenoValve program, the enVVe Valve incorporates design enhancements intended to improve performance, strength and long-term durability. The enVVe System directly addresses prior FDA concerns related to venous valves implanted via open surgical procedures. In addition to eliminating open surgical complications, its transcatheter approach is expected to broaden adoption by appealing to a wider range of implanting physicians including vascular surgeons, interventional radiologists, and interventional cardiologists.

The Company has completed pre-clinical testing on the enVVe System and has begun discussions with the FDA regarding the enVVe pivotal trial, which it expects to begin in 2026.

VenoValve

In March 2021, the Company received FDA investigational device exemption (“IDE”) approval to initiate the SAVVE® (Surgical Anti-reflux Venous Valve Endoprosthesis) U.S. pivotal clinical study evaluating the VenoValve. The prospective, multi-center, single-arm study enrolled 75 patients with severe CVI. An application seeking pre-market approval for the VenoValve was filed in November of 2024. In August of 2025 the Company received a non-approvable letter from the FDA for the VenoValve and a subsequent appeal was unsuccessful.

Most medical devices start out as surgical iterations and transition to less invasive, trans-catheter delivered versions over time. The Company’s strategy was to first develop the VenoValve, and then to transition to enVVe. That strategy remains intact. The enVVe System could not have been developed without the experience gained from the VenoValve. Because the VenoValve was not approved by the FDA, the Company has elected to forego any potential approval and commercialization efforts outside of the U.S. for the VenoValve and to instead focus its resources on bringing enVVe to market.

Data from the SAVVE pivotal study has been presented at vascular conferences throughout the world and has been very well received. Clinicians recognize the need for a replacement venous valve for patients suffering from deep venous CVI and both the short-term and long-term VenoValve efficacy data has been extremely promising for this difficult to treat patient population. Although interest in a surgical replacement venous valve has been strong, clinicians recognize that long-term the large potential market is best served via a trans-catheter delivered iteration of the device. There continues to be significant interest from clinicians wanting to participate in the enVVe pivotal study.

RISK FACTORS

Summary

The risk factors described below are a summary of the principal risk factors associated with an investment in us. These are not the only risks we face. You should carefully consider these risk factors and the other reports and documents filed by us with the SEC.

	●	We have incurred significant losses since our inception, expect to incur significant losses in the future and may never achieve or sustain profitability;
	●	Our estimates of our expenses, ongoing losses, future revenue, capital requirements and our needs for, or ability to obtain, additional financing;
	●	We depend entirely on the successful and timely regulatory approval and commercialization of our current, and any future, product candidates which, similar to the VenoValve, may not receive regulatory approval or, if our current or future product candidates do receive regulatory approval, we may not be able to successfully commercialize them;
	●	The success of our current or future products, if approved, will be determined based on whether surgeons and patients in our target markets accept them;
	●	Failure to scale up the manufacturing process of our current or future product candidates in a timely manner, or at all;
	●	Our ability to retain and recruit key personnel, including the development of a sales and marketing infrastructure;
	●	Reliance on third party suppliers for certain components of our product candidates;
	●	If we successfully develop product candidates, our ability to commercialize and distribute our product candidates in the United States and internationally, depends on our ability to demonstrate the efficacy and financial viability of our products to doctors, hospitals, insurance companies, and other stakeholders;
	●	Changes in external competitive market factors;
	●	Uncertainties in generating sustained revenue or achieving profitability;
	●	Unanticipated working capital or other cash requirements;
	●	Changes in FDA regulations, including testing procedures, for medical devices and related promotional and marketing activities;
	●	Our ability to obtain and maintain intellectual property protection;
	●	Product liability lawsuits against us could cause us to incur substantial liabilities, limit sales of our existing product candidates and limit commercialization of any products that we may develop;
	●	Our ability to maintain the listing of our securities on the Nasdaq Capital Market; and
	●	Changes in our business strategy or an inability to execute our strategy due to unanticipated changes in the medical device industry.

Risks Related to Our Business and Strategy

We have incurred losses since our inception, expect to incur losses in the future and may never achieve or sustain profitability.

We have historically incurred losses and expect to continue incurring losses going forward. Our losses have resulted primarily from our research programs and the development of our product candidates as well as from costs related to general and administrative expenses relating to our operations. Currently, we are not generating revenue from operations, and we expect to incur losses for the foreseeable future as we seek to obtain regulatory approval for our product candidates. Additionally, we expect that our general and administrative expenses will increase due to the additional operational costs associated with our clinical studies, as well as the anticipated expansion of our operations to commercialize our products if we receive FDA approval. We do not expect to generate significant revenue until we are able to commercialize one or more of our product candidates after receiving FDA approval, or if any of our product candidates are licensed or sold, if ever. We may never generate significant revenue or become profitable. Even if we do achieve profitability, we may be unable to sustain or increase profitability on a quarterly or annual basis. Our failure to achieve and subsequently sustain profitability could harm our business, financial condition, results of operations and cash flows.

We currently depend entirely on the successful and timely regulatory approval and commercialization of our current product candidate, and any future product candidates, which may not receive regulatory approval or, if any of our product candidates do receive regulatory approval, we may not be able to successfully commercialize them.

We currently have one product candidate, the enVVe System, and our business presently depends entirely on our success with this product candidate. In order for our product candidate to succeed it needs to be approved by regulatory authorities, which may never happen. Our product candidate is based on technologies that have not been used previously in the manner we propose. Market acceptance of our product candidates will largely depend on our ability to demonstrate their relative safety, efficacy, cost-effectiveness and ease of use. We may not be able to successfully develop and commercialize our product candidate. If we fail to do so, we will not be able to generate substantial revenues, if any.

We are subject to rigorous and extensive regulation by the FDA in the United States and by comparable agencies in other jurisdictions, including the European Medicines Agency, or EMA, in the European Union, or EU. Our product candidate is currently in development, and we have not received FDA approval for it. Our product candidate may not be marketed in the United States until they have been approved by the FDA and may not be marketed in other jurisdictions until they have received approval from the appropriate foreign regulatory agencies. A product candidate requires significant research, development, pre-clinical testing and extensive clinical investigation before submission of any regulatory application for marketing approval. For example, on August 19, 2025, the Company received a not-approvable letter from the FDA in response to its PMA application for the VenoValve. While the enVVe System is different than the VenoValve in that it is a non-surgical, transcatheter based replacement venous valve, the enVVe System may also not receive FDA approval.

Obtaining regulatory approval requires substantial time, effort and financial resources, and we may not be able to obtain approval of any of our product candidates on a timely basis, or at all. The number, size, design and focus of pre-clinical and clinical trials that will be required for approval by the FDA, the EMA or any other foreign regulatory agency varies depending on the device, the disease or condition that the product candidates are designed to address and the regulations applicable to particular products. Pre-clinical and clinical data can be interpreted in different ways, which could delay, limit or preclude regulatory approval. The FDA, the EMA and other foreign regulatory agencies can delay, limit or deny approval of a product for many reasons, including, but not limited to:

	●	a product candidate may not be shown to be safe or effective;
	●	the clinical and other benefits of a product candidate may not outweigh its safety risks;
	●	we may not be able to enroll enough patients to complete our product studies;
	●	clinical trial results may be negative or inconclusive, or adverse medical events may occur during a clinical trial;
	●	trial patients may expire from reasons unrelated to our product, impairing our trials;
	●	the results of clinical trials may not meet the level of statistical significance required by regulatory agencies for approval;
	●	regulatory agencies may interpret data from pre-clinical and clinical trials in different ways than we do;
	●	regulatory agencies may not approve the manufacturing process or determine that the manufacturing is not in accordance with current good manufacturing practices, or cGMPs;
	●	a product candidate may fail to comply with regulatory requirements; and/or
	●	regulatory agencies might change their approval policies or adopt new regulations.

For example, with respect to the VenoValve, the FDA indicated that the favorable rVCSS data generated by the study to show clinical improvement, together with the improvements in pain scores and venous specific quality of life indicators was not sufficient on its own to determine favorability of the benefit risk profile for the VenoValve. The FDA also referenced the use of a hemodynamic measurement that correlates with patient improvement, concerns about bias and the possibility that clinical improvement occurred as a result of the patients being enrolled in a study and safety concerns attributed to the VenoValve open surgical procedure, and that required re-hospitalizations.

If our current and future product candidates are not approved at all or quickly enough to provide net revenues to defray our operating expenses, our business, financial condition, operating results and prospects could be harmed.

If we are unable to successfully raise additional capital, our future clinical trials and product development could be limited and our long-term viability may be threatened.

We have experienced negative operating cash flows since our inception and have funded our operations primarily from proceeds received from sales of our capital stock, and the issuance of convertible and non-convertible notes. We will need to seek additional funds in the future through equity or debt financings, or strategic alliances with third parties, either alone or in combination with equity financings, to complete our product development initiatives. These financings could result in substantial dilution to the holders of our common stock or require contractual or other restrictions on our operations or on alternatives that may be available to us. If we raise additional funds by issuing debt securities, these debt securities could impose significant restrictions on our operations. Any such required financing may not be available in amounts or on terms acceptable to us, and the failure to procure such required financing could have a material and adverse effect on our business, financial condition and results of operations, or threaten our ability to continue as a going concern.

Our present and future capital requirements will be significant and will depend on many factors, including:

	●	the progress and results of our development efforts for our product candidates;
	●	the costs, timing and outcome of regulatory review of our product candidates;
	●	the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims;
	●	the effect of competing technological and market developments;
	●	the cost associated with commercialization of our product candidates once approved by the FDA;
	●	market acceptance of our product candidates;
	●	the rate of progress in establishing coverage and reimbursement arrangements with domestic and international commercial third-party payors and government payors;
	●	the ability to achieve revenue growth and improve gross margins;
	●	the extent to which we acquire or in-license other products and technologies; and
	●	legal, accounting, insurance and other professional and business-related costs.

We may not be able to acquire additional funds on acceptable terms, or at all. If we are unable to raise adequate funds, we may have to liquidate some or all of our assets or delay, reduce the scope of or eliminate some or all of our development programs.

If we do not have, or are not able to obtain, sufficient funds, we may be required to delay development or commercialization of our product candidates. We also may have to reduce the resources devoted to our product candidates or cease operations. Any of these factors could harm our operating results.

We may never be able to generate sufficient revenue from the commercialization of our product candidates to achieve and maintain profitability.

Our ability to operate profitably in the future will depend upon, among other items, our ability to (i) fully develop product candidates, (ii) scale up our business and operational structure, (iii) obtain regulatory approval of product candidates from the FDA and foreign regulators, (iv) market and sell product candidates, (v) successfully gain market acceptance of our product candidates by doctors and patients, and (vi) obtain sufficient and on-time supply of components from our third-party suppliers. If our product candidates are never successfully commercialized, we may never receive a return on our investments in product development, regulatory compliance, manufacturing, and quality assurance, which may cause us to fail to generate revenue and gain economies of scale from such investments.

We only utilize a few suppliers for porcine tissue for our product candidates and the loss of a supplier could have an adverse impact on our business.

We rely on two domestic third-party vendors to supply porcine tissue for our product candidates. Our ability to supply our current and future product candidates commercially, if approved, depends, in part, on our ability to obtain this porcine tissue in accordance with our specifications and with regulatory requirements and in sufficient quantities to meet demand. Our ability to obtain porcine tissue may be affected by matters outside our control, including that these suppliers may cancel our arrangements on short notice or have disruptions to their operations.

If we are required to establish additional or replacement suppliers for the porcine tissue, it may not be accomplished timely and our operations could be disrupted. Even if we are able to find replacement suppliers, the replacement suppliers may need to be qualified and may require additional regulatory authority approval, which could result in further delay. In the event of a supply disruption, our product inventories may be insufficient to supply our customers and the development of any future product candidates would be delayed, limited or prevented, which could have an adverse impact on our business.

We depend upon third-party suppliers for certain components of our product candidates, making us vulnerable to supply problems and price fluctuations, which could harm our business.

We rely on a number of third-party suppliers to provide certain components of our product candidates. We do not have long-term supply agreements with most of our suppliers, and, in many cases, we purchase goods on a purchase order basis. Our suppliers may encounter problems for a variety of reasons, including unanticipated demand from larger customers, failure to follow specific protocols and procedures, failure to comply with applicable regulations, equipment malfunction, quality or yield problems and environmental factors, any of which could delay or impede their ability to meet our demand. Our reliance on these third-party suppliers also subjects us to other risks that could harm our business, including:

	●	interruption of supply resulting from modifications to, or discontinuation of, a supplier’s operations;
	●	delays in product shipments resulting from defects, reliability issues or changes in components from suppliers;
	●	price fluctuations due to a lack of long-term supply arrangements for key components with our suppliers;
	●	errors in manufacturing components, which could negatively impact the effectiveness or safety of our product candidates or cause delays in shipment of our product candidates;
	●	discontinued production of components, which could significantly delay our production and sales and impair operating margins;
	●	inability to obtain adequate supplies in a timely manner or on commercially reasonable terms;
	●	difficulty locating and qualifying alternative suppliers, especially with respect to our sole-source supplies;
	●	delays in production and sales caused by switching components, which may require product redesign and/or new regulatory submissions;
	●	delays due to evaluation and testing of devices from alternative suppliers and corresponding regulatory qualifications;
	●	non-timely delivery of components due to our suppliers supplying products for a range of customers;
	●	the failure of our suppliers to comply with strictly enforced regulatory requirements, which could result in disruption of supply or increased expenses; and
	●	inability of suppliers to fulfill orders and meet requirements due to financial hardships.

In addition, there are a limited number of suppliers and third-party manufacturers that operate under the FDA’s Quality System Regulation, or QSR, requirements, maintain certifications from the International Organization for Standardization that are recognized as harmonized standards in the European Economic Area, or EEA, and that have the necessary expertise and capacity to supply components for our product candidates. As a result, it may be difficult for us to locate manufacturers for our anticipated future needs, and our anticipated growth may strain the ability of our current suppliers to deliver products, materials and components to us. If we are unable to arrange for third-party manufacturing of components for our product candidates, or to do so on commercially reasonable terms, we may not be able to complete development of, market and sell our current or new product candidates. Further, any supply interruption from our suppliers or failure to obtain additional suppliers for any of the components used in our product candidates would limit our ability to manufacture our product candidates. Failure to meet these commitments could result in legal action by our customers, loss of customers or harm to our ability to attract new customers, any of which could have a material and adverse effect on our business, financial condition, results of operations and growth.

If we successfully develop product candidates, which at this time will likely take several years at a minimum, we will have to demonstrate the efficacy and financial viability of our products to doctors, hospitals, insurance companies, and other stakeholders.

There are multiple stakeholders that determine the success of a medical device, including doctors, hospitals, medical insurance companies, and others. Educating these stakeholders on the benefits of product candidates will require a significant commitment by a marketing team and sales organization. Surgeons and hospitals may be slow to change their practices because of familiarity with existing devices and/or treatments, perceived risks arising from the use of new devices, lack of experience using new devices, lack of clinical data supporting the benefits of such devices or the cost of new devices. There may never be widespread adoption of our product candidates by surgeons and hospitals. In addition, medical insurance companies would need to understand the costs and benefits of our product candidates compared to the existing standards of care, if they are to provide reimbursement for the cost of our product candidates and the procedures to implant our product candidates. We may have difficulty and may never achieve the market acceptance that we need from doctors, hospitals, medical insurance companies and others that are necessary for a successful product.

We may be unable to convince hospital facilities to approve the use of our product candidates.

In the United States, in order for surgeons to use our product candidates, the hospital facilities where these surgeons treat patients will typically require that the product candidates receive approval from the facility’s value analysis committee (“VAC”). VACs typically review the comparative effectiveness and cost of medical devices used in the facility. The makeup and evaluation processes for VACs vary considerably, and it can be a lengthy, costly and time-consuming effort to obtain approval by the relevant VAC. For example, even if we have an agreement with a hospital system for the purchase of a product, in most cases, they must obtain VAC approval by each hospital within the system to sell at that particular hospital. Additionally, hospitals typically require separate VAC approval for each specialty in which a product is used, which may result in multiple VAC approval processes within the same hospital even if such product has already been approved for use by a different specialty group. VAC approval is often needed for each different product to be used by the surgeons in that specialty. In addition, hospital facilities and group purchasing organizations, or GPOs, which manage purchasing for multiple facilities, may also require us to enter into a purchasing agreement and satisfy numerous elements of their administrative procurement process, which can also be a lengthy, costly and time-consuming effort. If we do not receive access to hospital facilities in a timely manner, or at all, via these VAC and purchasing contract processes, or otherwise, or if we are unable to secure contracts on commercially reasonable terms in a timely manner, or at all, our costs may increase, our sales may decrease and our operating results may be harmed.

We face significant competition and our business prospects will depend on our ability to develop and commercialize our current product candidates and may also depend on our ability to develop additional product candidates.

The medical device industry is highly competitive and subject to rapid change and technological advancements. New technologies, techniques or products could emerge that might make our products obsolete or offer better combinations of price and performance than the products that we plan to offer. Therefore, it is important to our business that we continue to develop and enhance our product candidate offerings and potentially introduce new product candidates.

Developing new product candidates is expensive and time-consuming. Even if we are successful in developing additional product candidates, the success of any new product candidates or enhancements to existing product candidates will depend on several factors, including our ability to:

	●	properly identify and anticipate surgeon and patient needs;
	●	develop and introduce new product candidates or enhancements in a timely manner;
	●	develop an effective and dedicated sales and marketing team;
	●	avoid infringing upon the intellectual property rights of others;
	●	demonstrate, if required, the safety and efficacy of new product candidates with data from pre-clinical studies and clinical trials;
	●	obtain the necessary regulatory clearances or approvals for new product candidates or enhancements;
	●	be fully FDA-compliant with marketing of new product candidates or modified product candidates;
	●	provide adequate training to potential users of our product candidates; and
	●	receive adequate coverage and reimbursement for procedures performed with our product candidates.

If we are unsuccessful in developing and commercializing additional devices in other areas, our ability to realize our revenue may be impaired.

Existing markets for surgical devices are characterized by rapid technological change and innovation. It is critical to our success that we anticipate changes in technology and customer requirements and physician, hospital and healthcare provider practices. It is also important that we successfully introduce new, enhanced and competitive product candidates to meet our prospective customers’ needs on a timely and cost-effective basis. At the same time, however, we must carefully manage our introduction of new product candidates. If potential customers believe that such product candidates will offer enhanced features or be sold for a more attractive price, they may delay purchases until such product candidates are available. We may also continue to offer older products as we transition to new product candidates, and we may not have sufficient experience managing transitions. If we do not successfully innovate and introduce new technology into our anticipated product lines or successfully manage the transitions of our technology to new product offerings, our revenue, results of operations and business could be adversely impacted.

Our competitors may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, industry standards, distribution reach or customer requirements. We anticipate that we will face strong competition in the future as current or future competitors develop new or improved product candidates and as new companies enter the market with novel technologies.

If we are unable to produce an adequate supply of our product candidates for use in our current and planned clinical trials or for commercialization because of our limited manufacturing resources or our facility is damaged or becomes inoperable, our regulatory, development and commercialization efforts may be delayed.

Our manufacturing resources for our product candidates are limited. We currently manufacture our product candidates for our research and development and clinical trial purposes at our manufacturing facility in Irvine, California. If our existing manufacturing facility experiences a disruption, we would have no other means of manufacturing our product candidates until we are able to restore the manufacturing capability at our current facility or develop alternative manufacturing facilities. Any damage to or destruction of our facilities or our equipment, prolonged power outage or contamination at our facilities would significantly impair our ability to produce our product candidates and prepare our product candidates for clinical trials.

Additionally, to produce our product candidates in the quantities that we anticipate will be required for commercialization, we will have to increase or “scale up” our production process over the current level of production. We may encounter difficulties in scaling up our production, including issues involving yields, controlling and anticipating costs, quality control and assurance, supply and shortages of qualified personnel. If our scaled-up production process is not efficient or results in a product that does not meet quality or other standards, we may be unable to meet market demand and our revenues, business and financial prospects would be adversely affected. Further, third parties with whom we may develop relationships may not have the ability to produce the quantities of the materials we may require for clinical trials or commercial sales or may be unable to do so at prices that allow us to price our products competitively.

Our facility and equipment would be costly to replace and could require substantial lead time to repair or replace. The facility may be harmed or rendered inoperable by natural or man-made disasters, including earthquakes, flooding, fire, vandalism and power outages, which may render it difficult to operate our business for some period of time. While we have taken precautions to safeguard our facilities, any inability to operate our business during such periods could lead to the loss of customers or harm to our reputation. We also possess insurance for damage to our property and the disruption of our business, but this insurance may not be sufficient to cover all of our potential losses and this insurance may not continue to be available to us on acceptable terms, or at all.

We currently have no sales and limited marketing infrastructure and we may not be able to build a sales and marketing infrastructure sufficient for us to commercialize our current product candidate or future product candidates, if approved, and may be unable to do so or may never generate sufficient revenue to achieve or sustain profitability.

In order to commercialize products that are approved by regulatory agencies, we will have to increase our expenditures to undertake development or commercialization activities. If we are unable to successfully execute commercialization activities, we may have to curtail the development of our product candidates, reduce or delay development programs, delay potential commercialization of our product candidates or reduce the scope of any sales or marketing activities.

If it becomes necessary for us to establish a sales and marketing infrastructure, we may not be able to do so or we may not realize a positive return on this investment. We would have to compete with established and well-funded medical device companies to recruit, hire, train and retain sales and marketing personnel. Once hired, the training process is lengthy because it requires significant education of new sales representatives to achieve the level of clinical competency with our products expected by specialists. Upon completion of the training, we expect our sales representatives would typically require lead time in the field to grow their network of accounts and achieve the productivity levels we expect them to reach in any individual territory. If we are unable to attract, motivate, develop and retain a sufficient number of qualified sales personnel, or if our sales representatives do not achieve the productivity levels in the time period we expect them to, our revenue will not grow at the rate we expect and our business, results of operations and financial condition will suffer. Also, to the extent we hire sales personnel from our competitors, we may be required to wait until applicable non-competition provisions have expired before deploying such personnel in restricted territories or incur costs to relocate personnel outside of such territories. Any of these risks may adversely affect our ability to increase sales of our product candidates. If we are unable to expand our sales and marketing capabilities, we may not be able to effectively commercialize our product candidates, which would adversely affect our business, results of operations and financial condition.

Product liability lawsuits against us could cause us to incur substantial liabilities, limit sales of our existing product candidates and limit commercialization of any products that we may develop.

Our business exposes us to the risk of product liability claims that are inherent in the manufacturing, distribution, and sale of medical devices. This risk exists even if a device is cleared or approved for commercial sale by the FDA and manufactured in facilities licensed and regulated by the FDA or an applicable foreign regulatory authority. Manufacturing and marketing of our commercial devices and clinical testing of our product candidates, may expose us to product liability and other tort claims. Furthermore, surgeons may misuse our product candidates or use improper techniques if they are not adequately trained, potentially leading to injury and an increased risk of product liability. If our product candidates are misused or used with improper technique, we may become subject to costly litigation by our customers or their patients. Regardless of the merit or eventual outcome, product liability claims may result in:

	●	significant litigation costs;
	●	decreased demand for our product candidates and any future product candidates that we may develop;
	●	damage to our reputation;
	●	withdrawal of clinical trial participants;
	●	substantial monetary awards to trial participants, patients or other claimants;
	●	loss of revenue; and
	●	the inability to commercialize any product candidates that we may develop.

Although we maintain liability insurance, the coverage limits of our insurance policies may not be adequate, and one or more successful claims brought against us may have a material adverse effect on our business and results of operations. If we are unable to obtain insurance in the future at an acceptable cost or on acceptable terms with adequate coverage, we will be exposed to significant liabilities.

The loss of our executive officers or our inability to attract and retain qualified personnel may adversely affect our business, financial conditions and results of operations.

Our business and operations depend to a significant degree on the skills, efforts and continued services of our executive officers who have critical industry experience and relationships. Although we have entered into employment agreements with our executive officers, they may terminate their employment with us at any time. Accordingly, these executive officers may not remain associated with us. The efforts of these persons will be critical to us as we continue to develop our product candidates and business. We do not carry key person life insurance on any of our management, which would leave our company uncompensated for the loss of any of our executive officers.

Further, competition for highly skilled and qualified personnel is intense. As such, our future viability and ability to achieve sales and profit will also depend on our ability to attract, train, retain and motivate highly qualified personnel in the diverse areas required for continuing our operations. If we were to lose the services one or more of our current executive officers or if we are unable to attract, hire and retain qualified personnel, we may experience difficulties in competing effectively, developing and commercializing our products and implementing our business strategies, which could have a material adverse effect on our business, operations and financial condition.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

The Company has incurred significant operating losses which have generated net operating loss carry-forwards for both federal and state purposes. Other than federal NOL carryforwards generated after 2017, our NOL carryforwards will expire if not used over the next four years. Our ability to realize the benefits of these NOL carryforwards will depend on our ability to generate income.

Further, our ability to realize the benefits of NOL carryforwards are limited because of ownership changes. In general, a corporation that undergoes an “ownership change” (generally defined as a greater than 50% change (by value) in its equity ownership over a rolling three (3) year period) may be subject to limitations on its ability to utilize its NOLs and certain credit carryforwards to offset future taxable income and taxes. We have analyzed the tax impacts of ownership changes that occurred in 2018, 2021, 2023, 2024, and in 2025. While those ownership changes may have resulted in limits to the amount of NOLs that can be used in a given year, these are all post 2017 NOLs and are carried forward indefinitely.

Future changes in our stock ownership, as well as other changes that may be outside of our control, could result in additional ownership changes. Our NOLs and credit carryforwards may also be limited under similar provisions of state law. We have recorded a full valuation allowance related to our NOLs and other deferred tax assets due to the uncertainty of the ultimate realization of the future tax benefits of such assets.

Risks Related to Regulatory Approval and Other Governmental Regulations

Our business and product candidates are subject to extensive governmental regulation and oversight, and our failure to comply with applicable regulatory requirements could harm our business.

Our product candidates and operations are subject to extensive regulation in the United States by the FDA and by regulatory agencies in other countries where we anticipate conducting business activities. The FDA regulates the development, testing, manufacturing, labeling, storage, record-keeping, promotion, marketing, sales, distribution and post-market support and reporting of medical devices in the United States. The regulations to which we are subject are complex and may become more stringent over time. Regulatory changes could result in restrictions on our ability to carry on or expand our operations, higher than anticipated costs or lower than anticipated sales.

In order to conduct a clinical investigation involving human subjects for the purpose of demonstrating the safety and effectiveness of a medical device, a company must, among other things, apply for and obtain Institutional Review Board, or IRB, approval of the proposed investigation. In addition, if the clinical study involves a “significant risk” (as defined by the FDA) to human health, the sponsor of the investigation must submit and obtain FDA approval of an IDE application. Our product candidates are considered significant risk devices requiring IDE approval prior to investigational use. We may not be able to obtain FDA and/or IRB approval to undertake clinical trials in the United States for any new devices we intend to market in the United States in the future. If we do obtain such approvals, we may not be able to conduct studies which comply with the IDE and other regulations governing clinical investigations or the data from any such trials may not support clearance or approval of the investigational device. Failure to obtain such approvals or to comply with such regulations could have a material adverse effect on our business, financial condition and results of operations. It is uncertain whether clinical trials will meet desired endpoints, produce meaningful or useful data and be free of unexpected adverse effects, or that the FDA will accept the validity of foreign clinical study data, and such uncertainty could preclude or delay market clearance or authorizations resulting in significant financial costs and reduced revenue.

The Company received a not-approvable letter from the FDA.

On August 19, 2025, the Company received a not-approvable letter from the FDA in response to its PMA application for the VenoValve. The letter indicated that the FDA completed its review of the VenoValve PMA application and determined that it is unable to approve the PMA for the VenoValve in its current form. In particular, the FDA indicated that the favorable rVCSS data generated by the study to show clinical improvement, together with the improvements in pain scores and venous specific quality of life indicators was not sufficient on its own to determine favorability of the benefit risk profile for the VenoValve. Without a specific hemodynamic measurement that correlates with patient improvement, the FDA raised concerns about bias and the possibility that clinical improvement occurred as a result of the patients being enrolled in a study. The FDA also focused on safety concerns which were attributed to the VenoValve open surgical procedure, and that required re-hospitalizations.

On September 18, 2025, the Company filed a request for supervisory appeal of the not-approvable letter from the Center for Devices and Radiological Health (CDRH) of the FDA received on August 19, 2025, in response to its PMA application for the VenoValve. The FDA provides several internal informal and formal mechanisms to challenge staff decisions, including scientific controversies. One mechanism is a request for supervisory review in which an appeal is made to the next line of supervision. These appeals involve a formal substantive request, an in-person meeting, and a decision. It also often includes multiple interactions even after an initial appeal decision is made. Internal Agency reviews are based on information already in the administrative file.

In October 2025, the Company completed an in-person meeting with the FDA. In addition to representatives from an outside firm specializing in FDA matters and appeals and representatives from the Company, the meeting also included a patient advocate from VenoValve U.S. pivotal study as well as one of the Company’s primary investigators from the trial. Several employees from the FDA attended the meeting including the Director of the Center for Devices and Radiological Health, who elected to hear the appeal and who will be issuing the appeal decision. The FDA meeting provided the Company with the opportunity to put the major adverse events—those tied to the SAVVE study’s safety endpoints—into the proper context. It also allowed the Company to re-emphasize the multiple physician-and patient-reported clinical benefits that comprise the totality of the evidence from the study, supported by firsthand perspectives shared by both the SAVVE study patient and investigator in attendance. Because there are no established industry or regulatory standards to determine the effectiveness for a replacement venous valve, it is necessary for the Company and the Agency to establish a new regulatory pathway for VenoValve effectiveness.

On November 13, 2025, the Company received an unfavorable decision from the FDA in response to its supervisory appeal of the not-approvable letter. The supervisory appeal upheld the review staff decision in the not-approvable letter that the VenoValve did not meet the standard of reasonable assurance of safety and effectiveness.

In light of receiving a not-approvable letter from the FDA and an unfavorable decision from the FDA in response to its supervisory appeal of the not-approvable letter, there can be no assurances that the Company will ever get regulatory approval for the VenoValve or for the enVVe System.

Our product candidates will be subject to extensive governmental regulation in foreign jurisdictions, such as the EEA, and our failure to comply with applicable requirements could cause our business, results of operations and financial condition to suffer.

In the EEA, our product candidates will need to comply with the Essential Requirements set forth in Medical Device Regulation. Compliance with these requirements is a prerequisite to be able to affix a CE mark to a product, without which a product cannot be marketed or sold in the EEA. To demonstrate compliance with the Essential Requirements and obtain the right to affix the CE mark to our product candidates, we must undergo a conformity assessment procedure, which varies according to the type of medical device and its classification. The conformity assessment procedure requires the involvement of a Notified Body, which is an organization designated by a competent authority of an EEA country to conduct conformity assessments. The Notified Body would audit and examine the Technical File and the quality system for the manufacture, design and final inspection of our products. The Notified Body issues a CE Certificate of Conformity following successful completion of a conformity assessment procedure and quality management system audit conducted in relation to the medical device and its manufacturer and their conformity with the Essential Requirements. This Certificate entitles the manufacturer to affix the CE mark to its medical products after having prepared and signed a related EC Declaration of Conformity.

As a general rule, demonstration of conformity of medical products and their manufacturers with the Essential Requirements must be based, among other things, on the evaluation of clinical data supporting the safety and performance of the products during normal conditions of use. Specifically, a manufacturer must demonstrate that the device achieves its intended performance during normal conditions of use and that the known and foreseeable risks, and any adverse events, are minimized and acceptable when weighed against the benefits of its intended performance, and that any claims made about the performance and safety of the device (e.g., product labeling and instructions for use) are supported by suitable evidence. This assessment must be based on clinical data, which can be obtained from (1) clinical studies conducted on the devices being assessed, (2) scientific literature from similar devices whose equivalence with the assessed device can be demonstrated or (3) both clinical studies and scientific literature. However, the pre-approval and post-market clinical requirements are much more rigorous. The conduct of clinical studies in the EEA is governed by detailed regulatory obligations. These may include the requirement of prior authorization by the competent authorities of the country in which the study takes place and the requirement to obtain a positive opinion from a competent Ethics Committee. This process can be expensive and time-consuming.

The FDA regulatory approval, clearance and license process is complex, time-consuming and unpredictable.

In the United States, our product candidates are regulated as medical devices. Before our medical device product candidates may be marketed in the United States, we must submit, and the FDA must approve a PMA application. For the PMA approval process, the FDA must determine that a proposed device is safe and effective for its intended use based, in part, on extensive data, including, but not limited to, technical, pre-clinical, clinical trial, manufacturing and labeling data. In addition, modifications to products that are approved through a PMA application generally require FDA approval. The time required to obtain approval, clearance or license by the FDA to market a new therapy is unpredictable but typically takes years and depends upon many factors, including the substantial discretion of the FDA, especially after the Company received a not-approvable letter from the FDA related to the VenoValve. This timeline may be further extended as a result of the recent reduction in workforce that has taken place within the federal government, including at the FDA.

Our product candidates could fail to receive regulatory approval, clearance or license for many reasons, including the following:

	●	the FDA may disagree with the design or implementation of our clinical trials or study endpoints;
	●	we may be unable to demonstrate to the satisfaction of the FDA that our product candidates are safe and effective for their proposed indications or that our product candidates provide significant clinical benefits;
	●	the results of our clinical trials may not meet the level of statistical significance required by the FDA for approval, clearance or license or may not support approval of a label that could command a price sufficient for us to be profitable;
	●	the FDA may disagree with our interpretation of data from pre-clinical studies or clinical trials;
	●	the opportunity for bias in the clinical trials as a result of the open-label design may not be adequately handled and may cause our trial to fail;
	●	our product candidates may be subject to an FDA advisory committee review, which may be requested at the sole discretion of the FDA, and which may result in unexpected delays or hurdles to approval;
	●	the FDA may determine that the manufacturing processes at our facilities or facilities of third-party manufacturers with which we contract for clinical and commercial supplies are inadequate;
	●	the FDA may determine we cannot continue our clinical trials due to adverse patient reactions including patient deaths for reasons unrelated to our products; and
	●	the approval, clearance or license policies or regulations of the FDA may significantly change in a manner rendering our clinical data insufficient for approval.

Even if we were to obtain approval, clearance or license, the FDA may grant approval, clearance or license contingent on the performance of costly post-marketing clinical trials or may approve our product candidates with a label that does not include the labeling claims necessary or desirable for successful commercialization of our product candidates. Any of the above could materially harm our product candidates’ commercial prospects.

Even if our product candidates are approved by regulatory authorities, if we fail to comply with ongoing regulatory requirements, or if we experience unanticipated problems with our product candidates, our product candidates could be subject to restrictions or withdrawal from the market.

The manufacturing processes, post-approval clinical data and promotional activities of any product candidate for which we obtain marketing approval will be subject to continual review and periodic inspections by the FDA and other regulatory bodies. Even if regulatory approval of our product candidates is granted in the United States or elsewhere, the approval may be subject to limitations on the indicated uses for which the product candidates may be marketed or contain requirements for costly post-marketing testing and surveillance to monitor the safety or effectiveness of the product. Later discovery of previously unknown and unanticipated problems with our product candidates, including but not limited to unanticipated severity or frequency of adverse events, delays or problems with the manufacturer or manufacturing processes, or failure to comply with regulatory requirements, may result in restrictions on such product candidates or manufacturing processes, withdrawal of the product candidates from the market, voluntary or mandatory recall, fines, suspension of regulatory approvals, product seizures, injunctions or the imposition of civil or criminal penalties.

We are required to report certain malfunctions, deaths and serious injuries associated with our products once approved by regulatory bodies, which can result in voluntary corrective actions or agency enforcement actions.

All manufacturers marketing medical devices in the EEA are legally bound to report incidents involving devices they produce or sell to the regulatory agency, or competent authority, in whose jurisdiction the incident occurred. Under the EU Medical Devices Directive (Directive 93/42/EEC), an incident is defined as any malfunction or deterioration in the characteristics and/or performance of a device, as well as any inadequacy in the labeling or the instructions for use which, directly or indirectly, might lead to or might have led to the death of a patient, or user or of other persons or to a serious deterioration in their state of health. In addition, under the EU MDR, the manufacturers are obligated to publish Periodic Safety Update Report (annually for high risk devices) which will be uploaded to EUDAMED and require conformity assessment by Notified Bodies.

Malfunction or misuse of our product candidates could result in future voluntary corrective actions, such as recalls, including corrections (e.g., customer notifications), or agency action, such as inspection or enforcement actions. If malfunctions or misuse do occur, we may be unable to correct the malfunctions adequately or prevent further malfunctions or misuse, in which case we may need to cease manufacture and distribution of the affected products, initiate voluntary recalls, and redesign the products or the instructions for use for those products. Regulatory authorities may also take actions against us, such as ordering recalls, imposing fines, or seizing the affected products. Any corrective action, whether voluntary or involuntary, will require the dedication of our time and capital, may distract management from operating our business, and may harm our business, results of operations and financial condition.

Legislative or regulatory reforms in the United States or the EU may make it more difficult and costly for us to obtain regulatory clearances or approvals for product candidates or to manufacture, market or distribute product candidates after clearance or approval is obtained.

From time to time, legislation is drafted and introduced in the U.S. Congress that could significantly change the statutory provisions governing the regulation of medical devices or the reimbursement thereof. In addition, the FDA regulations and guidance are often revised or reinterpreted by the FDA in ways that may significantly affect our business and our product candidates. For example, as part of the Food and Drug Administration Safety and Innovation Act, or FDASIA, Congress reauthorized the Medical Device User Fee Amendments with various FDA performance goal commitments and enacted several “Medical Device Regulatory Improvements” and miscellaneous reforms, which are further intended to clarify and improve medical device regulation both pre- and post-clearance or approval. Any new statutes, regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of any future products or make it more difficult to manufacture, market or distribute our product candidates or future products. We cannot determine what effect changes in regulations, statutes, legal interpretation or policies, when and if promulgated, enacted or adopted may have on our business in the future. Such changes could, among other things, require:

	●	additional testing prior to obtaining clearance or approval;
	●	changes to manufacturing methods;
	●	recall, replacement or discontinuance of our systems or future products; or
	●	additional record keeping.

Any of these changes could require substantial time and cost and could harm our business and our financial results.

The highly publicized PIP scandal (use of non-medical grade silicone in breast implants) in 2010 led to publishing the first version of EU Medical Device Regulation (MDR) by European Commission in 2012. After 347 amendments by European Parliament in 2014, followed by various versions, the final version of the new EU Medical Device Regulation (MDR 2017/745) was published on May 5, 2017. Notified Bodies are currently not accepting any new CE Mark applications under MDD (Medical Device Directives). All new medical devices, including ours, must undergo assessment under MDR.

The changes from EU Medical Device Directives (MDD) to Medical Device Regulation (MDR) are significant, with stricter clinical requirements and post-market surveillance, shift from pre-approval to Life-cycle approach, centralized EUDAMED database for public transparency (e.g. Periodic Safety Update Reports) and device registration, more device specific requirements (e.g. Common Specifications), legal liability for defective devices, etc. The QMS audit under MDR will be much more rigorous, including audits and assessment of suppliers and device testing. In addition, EU MDR introduces new stakeholders participating during the application review process, which will result in a longer and more burdensome assessment of our new products. The new stakeholders will include Medical Device Coordination Group (MDCG) established by Member States and Expert Panels appointed by European Union.

Further, under either the FDA’s Medical Device Reporting or MDR regulations, we are required to report to the FDA any incident in which our product candidates may have caused or contributed to a death or serious injury or in which our product malfunctioned and, if the malfunction were to recur, would likely cause or contribute to death or serious injury. Any adverse event involving our products could result in future voluntary corrective actions, such as product actions or customer notifications, or regulatory authority actions, such as inspection, mandatory recall or other enforcement action. Repeated product malfunctions may result in a voluntary or involuntary product recall, which could divert managerial and financial resources, impair our ability to manufacture our product candidates in a cost-effective and timely manner and have an adverse effect on our reputation, financial condition and operating results.

Moreover, depending on the corrective action we take to redress a product’s deficiencies or defects, the FDA may require us, or we may decide that we will need, to obtain new approvals or clearances for the device before we may market or distribute the corrected device. Seeking such approvals or clearances may delay our ability to replace the recalled devices in a timely manner. Moreover, if we do not adequately address problems associated with our product candidates, we may face additional regulatory enforcement action, including FDA warning letters, product seizure, injunctions, administrative penalties, withdrawals or clearances or approvals or civil or criminal fines. We may also be required to bear other costs or take other actions that may have a negative impact on our sales as well as face significant adverse publicity or regulatory consequences, which could harm our business, including our ability to market our product candidates in the future.

We are subject to federal, state and foreign healthcare laws and regulations, and a finding of failure to comply with such laws and regulations could have a material and adverse effect on our business.

Our operations are, and will continue to be, directly and indirectly affected by various federal, state or foreign healthcare laws, including, but not limited to, those described below. These laws include:

	●	the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual for, or the purchase, order or recommendation of, any good or service for which payment may be made under federal healthcare programs, such as the Medicare and Medicaid programs. A person or entity does not need to have actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it to have committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act. Violations of the federal Anti-kickback Statute may result in substantial civil or criminal penalties, including criminal fines of up to $25,000, imprisonment of up to five years, civil penalties under the Civil Monetary Penalties Law of up to $50,000 for each violation, plus three times the remuneration involved, civil penalties under the federal False Claims Act of up to $11,000 for each claim submitted, plus three times the amounts paid for such claims and exclusion from participation in the Medicare and Medicaid programs;
	●	the federal False Claims Act, which prohibits, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid or other federal third-party payors that are false or fraudulent. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of the government and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines or settlement. When an entity is determined to have violated the False Claims Act, the government may impose penalties of not less than $5,500 and not more than $11,000, plus three times the amount of the damages that the government sustains due to the submission of a false claim and exclude the entity from participation in Medicare, Medicaid and other federal healthcare programs;
	●	the federal Civil Monetary Penalties Law, which prohibits, among other things, offering or transferring remuneration to a federal healthcare beneficiary that a person knows or should know is likely to influence the beneficiary’s decision to order or receive items or services reimbursable by the government from a particular provider or supplier;
	●	HIPAA, as amended by the HITECH Act, and their respective implementing regulations, which governs the conduct of certain electronic healthcare transactions and protects the security and privacy of protected health information. Failure to comply with the HIPAA privacy and security standards can result in civil monetary penalties up to $50,000 per violation, not to exceed $1.5 million per calendar year for non-compliance of an identical provision, and, in certain circumstances, criminal penalties with fines up to $250,000 per violation and/or imprisonment. State attorneys general can bring a civil action to enjoin a HIPAA violation or to obtain statutory damages up to $25,000 per violation on behalf of residents of his or her state. HIPAA also imposes criminal penalties for fraud against any healthcare benefit program and for obtaining money or property from a healthcare benefit program through false pretenses and provides for broad prosecutorial subpoena authority and authorizes certain property forfeiture upon conviction of a federal healthcare offense. Significantly, the HIPAA provisions apply not only to federal programs, but also to private health benefit programs. HIPAA also broadened the authority of the U.S. Office of Inspector General of the U.S. Department of Health and Human Services to exclude participants from federal healthcare programs;
	●	the federal physician sunshine requirements under the Patient Protection and Affordable Care Act, or PPACA, which requires certain manufacturers of drugs, devices, biologics and medical supplies to report annually to the U.S. Department of Health and Human Services information related to payments and other transfers of value to physicians, which is defined broadly to include other healthcare providers and teaching hospitals and ownership and investment interests held by physicians and their immediate family members. Manufacturers are required to submit reports by the 90^th day of each calendar year. Failure to submit the required information may result in civil monetary penalties up to an aggregate of $150,000 per year (and up to an aggregate of $1 million per year for “knowing failures”) for all payments, transfers of value or ownership or investment interests not reported in an annual submission, and may result in liability under other federal laws or regulations; and
	●	analogous state and foreign law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third- party payor, including commercial insurers; state laws that require device companies to comply with the industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers and other potential referral sources; state laws that require device manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts. Any failure by us to ensure that our employees and agents comply with applicable state and foreign laws and regulations could result in substantial penalties or restrictions on our ability to conduct business in those jurisdictions, and our results of operations and financial condition could be materially and adversely affected.

The risk of our being found in violation of these laws is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available under such laws, it is possible that some of our business activities, including our relationships with surgeons and other healthcare providers, some of whom recommend, purchase and/or prescribe our product candidates, and our distributors, could be subject to challenge under one or more of such laws.

If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we may be subject to penalties, including civil and criminal penalties, damages, fines, disgorgement, exclusion from governmental health care programs and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business.

Regulatory healthcare reform measures and other legislative changes may have a material and adverse effect on business, results of operations and financial condition.

FDA regulations and guidance are often revised or reinterpreted by FDA and such actions may significantly affect our business and our product candidates. Any new regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times for our product candidates. Delays in receipt of, or failure to receive, regulatory approvals for our product candidates would have a material and adverse effect on our business, results of operations and financial condition.

In March 2010, the PPACA was signed into law. Initially it included a deductible 2.3% excise tax on any entity that manufactures or imports medical devices offered for sale in the United States, with limited exceptions. Although this excise tax was permanently repealed on December 20, 2019, it or similar taxes, may be enacted in the future. Other elements of the PPACA remain in force, including comparative effectiveness research, an independent payment advisory board and payment system reforms, including shared savings pilots and other provisions, which may significantly affect the payment for, and the availability of, healthcare services and result in fundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business, results of operations and financial condition.

In addition, other legislative changes have been proposed and adopted in the United States since the PPACA was enacted. On August 2, 2011, the Budget Control Act of 2011 created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to providers up to 2% per fiscal year, which went into effect on April 1, 2013. The 2% reduction in Medicare payments to providers, originally triggered by the Budget Control Act of 2011, has been extended multiple times. Most recently, the Consolidated Appropriations Act, 2023 extended this 2% sequester through fiscal year 2032. On January 2, 2013, the American Taxpayer Relief Act of 2012, or the ATRA, was signed into law which further reduced Medicare payments to certain providers, including hospitals.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our product candidates, if approved, and services or additional pricing pressures.

Our relationships with physician consultants, owners and investors could be subject to additional scrutiny from regulatory enforcement authorities and could subject us to possible administrative, civil or criminal sanctions.

Federal and state laws and regulations impose restrictions on our relationships with physicians who are consultants, owners and investors. We may enter into consulting agreements, license agreements and other agreements with physicians in which we provide cash as compensation. We have or may have other written and oral arrangements with physicians, including for research and development grants and for other purposes.

We could be adversely affected if regulatory agencies were to interpret our financial relationships with these physicians, who may be in a position to influence the ordering of and use of our product candidates for which governmental reimbursement may be available, as being in violation of applicable laws. If our relationships with physicians are found to be in violation of the laws and regulations that apply to us, we may be required to restructure the arrangements and could be subject to administrative, civil and criminal penalties, including exclusion from participation in government healthcare programs, imprisonment, and the curtailment or restructuring of our operations, any of which could negatively impact our ability to operate our business and our results of operations.

Our company and many of our collaborators and potential collaborators are required to comply with the Federal Health Insurance Portability and Accountability Act of 1996, the Health Information Technology for Economic and Clinical Health Act and implementing regulation affecting the transmission, security and privacy of health information, and failure to comply could result in significant penalties.

Numerous federal and state laws and regulations, including the Health Insurance Portability and Accountability Act of 1996, or HIPAA, and the Health Information Technology for Economic and Clinical Health Act, or the HITECH Act, govern the collection, dissemination, security, use and confidentiality of health information that identifies specific patients. HIPAA and the HITECH Act require our surgeon and hospital customers and potential customers to comply with certain standards for the use and disclosure of health information within their companies and with third parties. The Privacy Standards and Security Standards under HIPAA establish a set of standards for the protection of individually identifiable health information by health plans, health care clearinghouses and certain health care providers, referred to as Covered Entities, and the business associates with whom Covered Entities enter into service relationships pursuant to which individually identifiable health information may be exchanged. Notably, whereas HIPAA previously directly regulated only these Covered Entities, the HITECH Act makes certain of HIPAA’s privacy and security standards also directly applicable to Covered Entities’ business associates. As a result, both Covered Entities and business associates are now subject to significant civil and criminal penalties for failure to comply with Privacy Standards and Security Standards.

HIPAA requires Covered Entities (like many of our customers and potential customers) and business associates to develop and maintain policies and procedures with respect to protected health information that is used or disclosed, including the adoption of administrative, physical and technical safeguards to protect such information. The HITECH Act expands the notification requirement for breaches of patient-identifiable health information, restricts certain disclosures and sales of patient-identifiable health information and provides for civil monetary penalties for HIPAA violations. The HITECH Act also increased the civil and criminal penalties that may be imposed against Covered Entities and business associates and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney fees and costs associated with pursuing federal civil actions. Additionally, certain states have adopted comparable privacy and security laws and regulations, some of which may be more stringent than HIPAA.

Any new legislation or regulation in the area of privacy and security of personal information, including personal health information, could also adversely affect our business operations. If we do not comply with existing or new applicable federal or state laws and regulations related to patient health information, we could be subject to criminal or civil sanctions and any resulting liability could adversely affect our financial condition.

In addition, countries around the world have passed or are considering legislation that would impose data breach notification requirements and/or require that companies adopt specific data security requirements. If we experience a data breach that triggers one or more of these laws, we may be subject to breach notification obligations, civil liability and litigation, all of which could also generate negative publicity and have a negative impact on our business.

We are currently, and in the future may be, subject to various governmental regulations related to the manufacturing of product candidates, and we may incur significant expenses to comply with, experience delays in our product commercialization as a result of and be subject to material sanctions if we or our contract manufacturers violate these regulations.

Our manufacturing processes and facility are required to comply with the FDA’s QSR, which covers the procedures and documentation of the design, testing, production, control, quality assurance, labeling, packaging, sterilization, storage, and shipping of product candidates. Although we believe we are compliant with the QSRs, the FDA enforces the QSR through periodic announced or unannounced inspections of manufacturing facilities. We have been, and anticipate in the future being, subject to such inspections, as well as to inspections by other federal and state regulatory agencies. We are required to register our manufacturing facility with the FDA and list all devices that are manufactured. We also operate an International Organization for Standards, or ISO, 13485 certified facility and annual audits are required to maintain that certification. The suppliers of our components are also required to comply with the QSR and are subject to inspections. We have limited ability to ensure that any such third-party manufacturers will take the necessary steps to comply with applicable regulations, which could cause delays in the delivery of our products. Failure to comply with applicable FDA requirements, or later discovery of previously unknown problems with our products or manufacturing processes, including our failure or the failure of one of our third-party manufacturers to take satisfactory corrective action in response to an adverse QSR inspection, can result in, among other things:

	●	administrative or judicially imposed sanctions;
	●	injunctions or the imposition of civil penalties;
	●	recall or seizure of our product candidates;
	●	total or partial suspension of production or distribution;
	●	the FDA’s refusal to grant future clearance or pre-market approval for our product candidates;
	●	withdrawal or suspension of marketing clearances or approvals;
	●	clinical holds;
	●	warning letters;
	●	refusal to permit the import or export of our product candidates; and
	●	criminal prosecution of us or our employees.

Any of these actions, in combination or alone, could prevent us from marketing, distributing, or selling our products and would likely harm our business. In addition, a product defect or regulatory violation could lead to a government-mandated or voluntary recall by us. Regulatory agencies in other countries have similar authority to recall devices because of material deficiencies or defects in design or manufacture that could endanger health. Any recall would divert management attention and financial resources, could expose us to product liability or other claims, including contractual claims from parties to whom we sold products and harm our reputation with customers. A recall involving any of our product candidates would be particularly harmful to our business and financial results and, even if we remedied a particular problem, would have a lasting negative effect on our reputation and demand for our products.

Risks Related to Our Intellectual Property

If we are unable to adequately protect our proprietary technology or obtain and maintain issued patents that are sufficient to protect our product candidates, others could compete against us more directly, which could harm our business, financial condition and results of operations.

Our success may depend in part on our ability to obtain and maintain patents and other intellectual property rights in the United States and elsewhere and protecting our proprietary technologies. If we do not adequately protect our intellectual property and proprietary technologies, competitors may be able to use our technologies and erode or negate any competitive advantage we may have, which could harm our business and ability to achieve profitability.

We have filed patent applications for our products and related intellectual property with the U.S. Patent and Trademark Office and in other jurisdictions. As of the December 31, 2025, we have been granted forty-two (42) patents including nine (9) in the United States and have another twenty-one (21) applications in various stages of review including six (6) in the United States.

Our patents may not have, or our pending patent applications that mature into issued patents may not include, claims with a scope sufficient to protect our products, any additional features we develop for our current products or any new products. Other parties may have developed technologies that may be related or competitive to our products, may have filed or may file patent applications and may have received or may receive patents that overlap or conflict with our patent applications, either by claiming the same methods or devices or by claiming subject matter that could dominate our patent position. The patent positions of medical device companies, including our patent position, may involve complex legal and factual questions, and, therefore, the scope, validity and enforceability of any patent claims that we may obtain cannot be predicted with certainty. Patents, if issued, may be challenged, deemed unenforceable, invalidated or circumvented. Proceedings challenging our patents could result in either loss of the patent or denial of the patent application or loss or reduction in the scope of one or more of the claims of the patent or patent application. In addition, such proceedings may be costly. Thus, any patents that we may own may not provide any protection against competitors.

Furthermore, though an issued patent is presumed valid and enforceable, its issuance is not conclusive as to its validity or its enforceability and it may not provide us with adequate proprietary protection or competitive advantages against competitors with similar products. Competitors may also be able to design around our patents. Other parties may develop and obtain patent protection for more effective technologies, designs or methods. We may not be able to prevent the unauthorized disclosure or use of our technical knowledge or trade secrets by consultants, suppliers, vendors, former employees and current employees. The laws of some foreign countries do not protect our proprietary rights to the same extent as the laws of the United States, and we may encounter significant problems in protecting our proprietary rights in these countries. If any of these developments were to occur, they each could have a negative impact on our business and competitive position.

Our ability to enforce our patent rights depends on our ability to detect infringement. It may be difficult to detect infringers who do not advertise the components that are used in their products. Moreover, it may be difficult or impossible to obtain evidence of infringement in a competitor’s or potential competitor’s product. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded if we were to prevail may not be commercially meaningful.

In addition, proceedings to enforce or defend our patents could put our patents at risk of being invalidated, held unenforceable or interpreted narrowly. Such proceedings could also provoke third parties to assert claims against us, including that some or all of the claims in one or more of our patents are invalid or otherwise unenforceable. If any of our patents covering our products are invalidated or found unenforceable, our financial position and results of operations could be negatively impacted. In addition, if a court found that valid, enforceable patents held by third parties covered one or more of our products, our financial position and results of operations could be harmed.

We rely upon unpatented trade secrets, unpatented know-how and continuing technological innovation to develop and maintain our competitive position, which we will seek to protect, in part, by entering into confidentiality agreements with our employees and our collaborators and consultants. We also have agreements with our employees and selected consultants that obligate them to assign their inventions to us and have non-compete agreements with some, but not all, of our consultants. It is possible that technology relevant to our business will be independently developed by a person that is not a party to such an agreement. Furthermore, if the employees and consultants who are parties to these agreements breach or violate the terms of these agreements, we may not have adequate remedies for any such breach or violation, and we could lose our trade secrets through such breaches or violations. Further, our trade secrets could otherwise become known or be independently discovered by our competitors.

Obtaining and maintaining our patent protection depends on compliance with various procedures, document submission requirements, fee payments and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

The U.S. Patent and Trademark Office, or USPTO, and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payments such as maintenance and annuity fee payments and other provisions during the patent procurement process as well as over the life span of an issued patent. There are situations in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case.

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights and we may be unable to protect our rights to, or use of, our technology.

Our success will depend in part on our ability to operate without infringing the intellectual property and proprietary rights of third parties. Our business, product candidates and methods could infringe the patents or other intellectual property rights of third parties.

The medical device industry is characterized by frequent and extensive litigation regarding patents and other intellectual property rights. Many medical device companies with substantially greater resources than us have employed intellectual property litigation as a way to gain a competitive advantage. We may become involved in litigation, oppositions, reexamination, protest or other potentially adverse intellectual property proceedings as a result of alleged infringement by us of the rights of others or as a result of priority of invention disputes with third parties, either in the United States or internationally. We may also become a party to patent infringement claims and litigation declared by the USPTO to determine the priority of inventions. Third parties may also challenge the validity of any of our issued patents and we may initiate proceedings to enforce our patent rights and prevent others from infringing on our intellectual property rights. Any claims relating to the infringement of third-party proprietary rights or proprietary determinations, even if not meritorious, could result in costly litigation, lengthy governmental proceedings, diversion of our management’s attention and resources, or entrance into royalty or license agreements that are not advantageous to us. In any of these circumstances, we may need to spend significant amounts of money, time and effort defending our position. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations.

Even if we are successful in these proceedings, we may incur substantial costs and divert management time and attention in pursuing these proceedings, which could have a material and adverse effect on us. If we are unable to avoid infringing the intellectual property rights of others, we may be required to seek a license, defend an infringement action or challenge the validity of intellectual property in court or redesign our product candidates.

Risks Related to Ownership of Our Securities

The trading price of our securities has been and is likely to continue to be volatile and could be subject to wide fluctuations in response to a variety of factors.

The trading price of our securities has been and is likely to continue to be volatile and could be subject to wide fluctuations in response to a variety of factors, which include:

	●	whether we achieve our anticipated corporate objectives;
	●	actual or anticipated fluctuations in our financial condition and operating results;
	●	changes in financial or operational estimates or projections;
	●	the development status of our product candidates and when our product candidates receive regulatory approval if at all (for example, receiving a not-approvable letter from the FDA related to any product candidate);
	●	our execution of our sales and marketing, manufacturing and other aspects of our business plan;

	●	performance of third parties on whom we rely to manufacture our product candidate components and product candidates, including their ability to comply with regulatory requirements;
	●	the results of our pre-clinical studies and clinical trials;
	●	results of operations that vary from those of our competitors and the expectations of securities analysts and investors;
	●	our announcement of significant contracts, acquisitions or capital commitments;
	●	announcements by our competitors of competing products or other initiatives;
	●	announcements by third parties of significant claims or proceedings against us;
	●	regulatory and reimbursement developments in the United States and internationally;
	●	future sales of our common stock to meet our business requirements;
	●	product liability claims;
	●	healthcare reform measures in the United States and elsewhere;
	●	receiving a deficiency notice from Nasdaq;
	●	additions or departures of key personnel; and
	●	general economic or political conditions in the United States or elsewhere.

In addition, the stock market in general, and the stock of medical device companies like ours, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the issuer. These market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance.

We have issued a significant number of options and warrants and may continue to do so in the future. The vesting and, if applicable, exercise of these securities and the sale of the shares of common stock issuable thereunder may dilute your percentage ownership interest and may also result in downward pressure on the price of our common stock.

As of the date of this prospectus, we have issued and outstanding options to purchase 181,996 shares of our common stock with a weighted average exercise price of $220.41 and warrants to purchase 177,921 shares of our common stock with a weighted average exercise price of $278.26. Further, we have 38,154 shares available for issuance under our Amended and Restated 2016 Omnibus Incentive Plan.

The number of shares subject to the Plan is automatically adjusted from time to time when the Company issues additional shares of common stock or securities that are convertible or exercisable into shares of common stock (other than pursuant to the Plan) such that shares authorized under the plan after such issuance shall be equal to at least 20% of the issued and outstanding shares of the Company on a fully diluted basis. Because the market for our common stock is thinly traded, the sales and/or the perception that those sales may occur, could adversely affect the market price of our common stock. Furthermore, the mere existence of a significant number of shares of common stock issuable upon vesting and, if applicable, exercise of these securities may be perceived by the market as having a potential dilutive effect, which could lead to a decrease in the price of our common stock.

We will need to raise additional capital to meet our business requirements in the future, and such capital raising may be costly or difficult to obtain and can be expected to dilute current stockholders’ ownership interests.

We will need to raise additional capital in the future. Such additional capital may not be available on reasonable terms or at all. Any future issuance of our equity or equity-backed securities may dilute then-current stockholders’ ownership percentages. If we are unable to obtain required additional capital, we may have to curtail our growth plans or cut back on existing business.

We may incur substantial costs in pursuing future capital financing, including investment banking fees, legal fees, accounting fees, securities law compliance fees, printing and distribution expenses and other costs. We may also be required to recognize non-cash expenses in connection with certain securities we may issue, such as convertible notes, restricted stock, stock options and warrants, which may adversely impact our financial condition.

Future sales or issuances of substantial amounts of our common stock could result in significant dilution.

Any future issuance of our equity or equity-backed securities, including, potentially, the issuance of securities in connection with a merger transaction, may dilute then-current stockholders’ ownership percentages and could also result in a decrease in the fair market value of our equity securities, because our assets would be owned by a larger pool of outstanding equity. As stated above, we intend to conduct additional rounds of financing in the future and we may need to raise additional capital through public or private offerings of our common stock or other securities that are convertible into or exercisable for our common stock. We may also issue securities in connection with hiring or retaining employees and consultants (including stock options issued under an equity incentive plan), as payment to providers of goods and services, in connection with future acquisitions or for other business purposes. Our Board of Directors may at any time authorize the issuance of additional common stock without stockholder approval, subject only to the total number of authorized shares of common stock set forth in our articles of incorporation. The terms of equity securities issued by us in future transactions may be more favorable to new investors, and may include dividend and/or liquidation preferences, superior voting rights and the issuance of warrants or other derivative securities, which may have a further dilutive effect. Also, the future issuance of any such additional shares of common stock or other securities may create downward pressure on the trading price of the common stock. There can be no assurance that any such future issuances will not be at a price (or exercise prices) below the price at which shares of the common stock are then traded on Nasdaq or other then-applicable over-the-counter quotation system or exchange.

Our failure to meet the continued listing requirements of Nasdaq could result in a de-listing of our Common Stock.

While we are currently in compliance with Nasdaq’s continued listing requirements, we have received deficiency notices in the past and there is no guarantee that we will be able to continue to meet the continued listing requirements of Nasdaq. In the event of a deficiency notice, we would expect to take actions to restore our compliance with Nasdaq Marketplace Rules and prevent future non-compliance. However, there can be no assurance we would be able to do so. In the event we are unable to do so, our securities may be delisted from The Nasdaq Stock Market. Such a delisting would likely have a negative effect on the price of our Common Stock and would impair your ability to sell or purchase our Common Stock when you wish to do so.

Provisions of our charter documents or Delaware law could delay or prevent an acquisition of us, even if the acquisition would be beneficial to our stockholders, which could make it more difficult for you to change management.

Provisions in our amended and restated certificate of incorporation and our amended and restated bylaws may discourage, delay or prevent a merger, acquisition or other change in control that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. In addition, these provisions may frustrate or prevent any attempt by our stockholders to replace or remove our current management by making it more difficult to replace or remove our board of directors. These provisions include, but are not limited to:

	●	a classified board of directors so that not all directors are elected at one time;
	●	a prohibition on stockholder action through written consent;
	●	no cumulative voting in the election of directors;
	●	the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a director;
	●	a requirement that special meetings of the stockholders may be called only by our chairman of the board, chief executive officer or president, or by a resolution adopted by a majority of our board of directors;
	●	an advance notice requirement for stockholder proposals and nominations;
	●	the authority of our board of directors to issue preferred stock with such terms as our board of directors may determine; and
	●	a requirement of approval of not less than 50% of all outstanding shares of our capital stock entitled to vote to amend any bylaws by stockholder action, or to amend specific provisions of our amended and restated certificate of incorporation.

In addition, the Delaware General Corporate Law, or DGCL, prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder, generally a person who, together with its affiliates, owns, or within the last three years has owned, 15% or more of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. Accordingly, the DGCL may discourage, delay, or prevent a change in control of our company.

Furthermore, our amended and restated certificate of incorporation specifies that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for most legal actions involving actions brought against us by stockholders. We believe this provision benefits us by providing increased consistency in the application of the DGCL by chancellors particularly experienced in resolving corporate disputes, efficient administration of cases on a more expedited schedule relative to other forums and protection against the burdens of multi-forum litigation. However, the provision may have the effect of discouraging lawsuits against our directors and officers.

We do not anticipate paying any cash dividends on our common stock in the foreseeable future and, as such, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

We have never declared or paid cash dividends on our common stock. We do not anticipate paying any cash dividends on our common stock in the foreseeable future. We currently intend to retain all available funds and any future earnings to fund the development and growth of our business. In addition, and any future loan arrangements we enter into may contain, terms prohibiting or limiting the amount of dividends that may be declared or paid on our common stock. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

USE OF PROCEEDS

We will not receive any proceeds from the resale of our Common Stock by the Selling Stockholders pursuant to this prospectus. However, we will receive the exercise price of any Common Stock issued to the Selling Stockholders upon cash exercise by them of their options. We would expect to use these proceeds, if any, for general working capital purposes. We have agreed to pay the expenses of registration of these shares.

PLAN OF DISTRIBUTION

In this section of the prospectus, the term “Selling Stockholder” means and includes:

●	the persons identified in the table above as the Selling Stockholders;

●	those persons whose identities are not known as of the date hereof but may in the future be eligible to receive options under the 2016 Plan; and

●	any of the donees, pledgees, distributees, transferees or other successors in interest of those persons referenced above who may: (a) receive any of the shares of our common stock offered hereby after the date of this prospectus and (b) offer or sell those shares hereunder.

The shares of our Common Stock offered by this prospectus may be sold from time to time directly by the Selling Stockholders. Alternatively, the Selling Stockholders may from time to time offer such shares through underwriters, brokers, dealers, agents or other intermediaries. The Selling Stockholders as of the date of this prospectus have advised us that there were no underwriting or distribution arrangements entered into with respect to the Common Stock offered hereby. The distribution of the Common Stock by the Selling Stockholders may be effected: in one or more transactions that may take place on The Nasdaq Capital Market (including one or more block transaction) through customary brokerage channels, either through brokers acting as agents for the Selling Stockholders, or through market makers, dealers or underwriters acting as principals who may resell these shares on The Nasdaq Capital Market; in privately-negotiated sales; by a combination of such methods; or by other means. These transactions may be effected at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at other negotiated prices. Usual and customary or specifically negotiated brokerage fees or commissions may be paid by the Selling Stockholders in connection with sales of our Common Stock.

The Selling Stockholders may enter into hedging transactions with broker-dealers in connection with distributions of the shares or otherwise. In such transactions, broker-dealers may engage in short sales of the shares of our Common Stock in the course of hedging the positions they assume with the Selling Stockholders. The Selling Stockholders also may sell shares short and redeliver the shares to close out such short positions. The Selling Stockholders may enter into option or other transactions with broker-dealers which require the delivery to the broker-dealer of shares of our Common Stock. The broker-dealer may then resell or otherwise transfer such shares of Common Stock pursuant to this prospectus.

The Selling Stockholders also may lend or pledge shares of our Common Stock to a broker-dealer. The broker-dealer may sell the shares of Common Stock so lent, or upon a default the broker-dealer may sell the pledged shares of Common Stock pursuant to this prospectus. Any securities covered by this prospectus which qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.

The Selling Stockholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their securities. There is no underwriter or coordinating broker acting in connection with the proposed sale of shares of Common Stock the Selling Stockholders.

Although the shares of Common Stock covered by this prospectus are not currently being underwritten, the Selling Stockholders or their underwriters, brokers, dealers or other agents or other intermediaries, if any, that may participate with the selling security holders in any offering or distribution of Common Stock may be deemed “underwriters” within the meaning of the Securities Act and any profits realized or commissions received by them may be deemed underwriting compensation thereunder.

Under applicable rules and regulations under the Exchange Act, any person engaged in a distribution of shares of the Common Stock offered hereby may not simultaneously engage in market making activities with respect to the Common Stock for a period of up to five days preceding such distribution. The Selling Stockholders will be subject to the applicable provisions of the Exchange Act and the rules and regulations promulgated thereunder, including without limitation Regulation M, which provisions may limit the timing of purchases and sales by the Selling Stockholders.

In order to comply with certain state securities or blue sky laws and regulations, if applicable, the Common Stock offered hereby will be sold in such jurisdictions only through registered or licensed brokers or dealers. In certain states, the Common Stock may not be sold unless they are registered or qualified for sale in such state, or unless an exemption from registration or qualification is available and is obtained.

We will bear all costs, expenses and fees in connection with the registration of the Common Stock offered hereby. However, the Selling Stockholders will bear any brokerage or underwriting commissions and similar selling expenses, if any, attributable to the sale of the shares of Common Stock offered pursuant to this prospectus. We have agreed to indemnify the Selling Stockholders against certain liabilities, including liabilities under the Securities Act, or to contribute to payments to which any of those security holders may be required to make in respect thereof.

There can be no assurance that the Selling Stockholders will sell any or all of the securities offered by them hereby.

DISCLOSURE OF COMMISSION POSITION ON

INDEMNIFICATION FOR SECURITIES LAWS VIOLATIONS

Section 145 of the DGCL inter alia, empowers a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Similar indemnity is authorized for such persons against expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of any such threatened, pending or completed action or suit if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and provided further that (unless a court of competent jurisdiction otherwise provides) such person shall not have been adjudged liable to the corporation. Any such indemnification may be made only as authorized in each specific case upon a determination by the stockholders or disinterested directors or by independent legal counsel in a written opinion that indemnification is proper because the indemnitee has met the applicable standard of conduct.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him under Section 145. We maintain policies insuring our officers and directors against certain liabilities for actions taken in such capacities, including liabilities under the Securities Act.

Section 102(b)(7) of the DGCL permits a corporation to include in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payment of dividends and unlawful stock purchase or redemption) or (iv) for any transaction from which the director derived an improper personal benefit.

Article 10 of the bylaws of the Company contains provisions which are designed to provide mandatory indemnification of directors and officers of the Company to the full extent permitted by law, as now in effect or later amended. The bylaws further provide that, if and to the extent required by the DGCL, an advance payment of expenses to a director or officer of the Company that is entitled to indemnification will only be made upon delivery to the Company of an undertaking, by or on behalf of the director or officer, to repay all amounts so advanced if it is ultimately determined that such director is not entitled to indemnification.

Item 9. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement.

(i) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

II-3

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(5) That every prospectus (i) that is filed pursuant to paragraph (4) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(6) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(7) To respond to requests for information that is incorporated by reference into the joint proxy statement/prospectus pursuant to Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(8) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(c) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
