PART I.

Overview

We are a medical device company committed to providing highly effective, non-invasive and cost-effective treatments for both oncological and non-oncological skin conditions. We use a proprietary low-energy X-ray technology known as superficial radiation therapy (SRT), which is a result of over a decade of dedicated research and development. We have successfully incorporated SRT into our portfolio of treatment devices: the SRT-100^TM, SRT-100+^TM and SRT-100 Vision^TM. To date, SRT technology has been used to effectively and safely treat oncological and non-oncological skin conditions in thousands of patients around the world. With the introduction of Sculptura™, we are branching out into cancer treatment that goes far beyond skin and will provide a revolutionary treatment option for patients around the world.

We were organized in 2010 as Sensus Healthcare, LLC, a Delaware limited liability company (the “Company”), was formed on May 7, 2010, to design, manufacture and market proprietary medical devices specializing in the treatment of non-melanoma skin cancers and other skin conditions, such as keloids, with superficial radiation therapy.company. In June 2010, Sensus Healthcare, LLC,January 2016, we completed a Florida limited liability company (“Sensus (FL)”) acquired all the assets associated with our primary product, the SRT-100, from Topex, Inc. for $1.3 million. Following this acquisition, we relaunched the SRT-100 under the Sensus Healthcare brand. In December 2011, we merged with Sensus (FL), with the Delaware limited liability company surviving the merger for the purpose of changing our domicile from Florida to Delaware. On January 1, 2016, Sensus Healthcare, LLC converted into a Delaware corporationcorporate conversion pursuant to a statutory conversion and we changed our name towhich Sensus Healthcare, Inc. As a result ofsucceeded to the corporate conversion, all holders of unitsbusiness of Sensus Healthcare, LLC became holders of common stock of Sensus Healthcare, Inc. Holders of warrantsLLC. In 2016 we completed an initial public offering and options to purchase units of Sensus Healthcare, LLC became holders of warrantsin 2018 we opened a subsidiary in Israel. The Company operates as one segment from its corporate headquarters located in Boca Raton, Florida.

SRT-100

The SRT-100 is a photon x-ray low energy superficial radiotherapy system that provides patients an alternative to surgery for treating non-melanoma skin cancers, including basal cell and squamous cell skin cancers and other skin conditions such as keloids. The SRT-100 is especially effective in treating primary lesions that would otherwise be difficult or require extensive surgery involving sensitive areas of the head and neck regions, such as the fold in the nose, eyelids, lips, corner of the mouth, and the lining of the ear, that would otherwise lead to a less than desirable cosmetic outcome. Superficial radiation therapy treatment procedures do not require the use of anesthetics and eliminates the need for skin grafting. TheWe believe that the SRT-100 provides healthcare providers and patients with a safe, virtually painless, and substantially non-scarring treatment option for non-melanoma skin cancer and other skin conditions, such as keloids. It allows dermatologists to retain non-melanoma skin cancer patients, rather than referring them to specialists, while offering radiation oncologists an alternative to costly linear accelerator–based treatments with a process that is less invasive, more time-efficient, and improves practice economics. Our revenue is primarily derived from sales of our SRT-100 product line.

Corporate Conversion

On January 1, 2016, we converted from a Florida limited liability company to a Delaware corporation. The purpose of the corporate conversion was to reorganize our corporate structure in advance of our initial public offering, or IPO, so that we would be a corporation rather than a limited liability company and so that our existing investors own our common stock rather than equity interests in a limited liability company. References elsewhere in this Annual Report on Form 10-K to our capitalization and other matters pertaining to our equity and shares prior to the corporate conversion relate to the capitalization and equity and shares of Sensus Healthcare, LLC, and after the corporate conversion, to Sensus Healthcare, Inc.

Initial Public Offering

On June 8, 2016, we completed an IPO of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of their over-allotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Act pursuant to a registration statement on Form S-1, as amended (File No. 333-209451), which was declared effective by the SEC on June 2, 2016. The registration statement registered an aggregate of 2,300,000 units, including 300,000 units to cover the over-allotment option. The offering commenced on June 2, 2016 and did not terminate before all of the units in the IPO that were registered in the registration statement were sold. Northland Securities, Inc. and Neidiger, Tucker, Bruner, Inc. acted as joint book-running managers for the offering.

We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 million and other offering expenses of approximately $1.4 million.

Our Products and Services 

SRT-100 

We offer the SRT-100 product family, which we anticipate will be complemented by additional models and options in the future. Our technology is based on several key needs and requirements, including the need for a dedicated and cost-effective device for the treatment of skin cancer, keloids, and other skin conditions. The SRT-100 provides the following clinical and functional advantages:

SRT-100 Vision

The SRT-100 Vision provides customers with additional options compared to the SRT-100 base model. These additional options allow for dedicated treatment planning and full treatment progression documentation in a patient’s record. The SRT-100 Vision provides the user with a unique superficial radiation therapy-tailored treatment planning application that integrates the embedded high frequency ultrasound imaging module, volumetric tumor analysis, beam margins planning, and comprehensive dosimetry parameters. This allows the user to precisely and more accurately plan and prescribe the patient-specific treatment course to maximize patient outcomes and workflow efficiency. The SRT-100 Vision also offers a comprehensive control console and workflow management control console that provides full record and verify treatment tracing, operator-level access and functional control, audio-visual patient and treated lesion monitoring, and advanced dosimetry setting and tracing.

SRT-100 Plus

In 2018, we announced U.S. Food and Drug Administration, or FDA, clearance of our SRT-100+. The SRT-100+ offers all the same features as the SRT-100, with the addition of:

Sculptura

In February 2019, we announced FDA clearance of our Sculptura product, which is our proprietary modulated robotic brachytherapy radiation oncology system that provides targeted directional anisotropic radiation therapy (ART) and brachytherapy that uses patented Beam Sculpting™ capabilities to treat various cancers during surgery. This system has the potential to give surgeons and radiation oncologists at hospitals and cancer centers the ability to eliminate weeks of post-operative radiation treatments that patients typically must undergo after surgery and also result in similar or better outcomes to current radiation treatments today, with significantly less collateral damage. Sculptura has several exclusive features, including 3D Beam Sculpting™, respiratory motion tracking, embedded image guidance and treatment area illumination.

Sentinel service program

We offer the Sentinel service program, which provides our customers comprehensive protection for their SRT-100 and SRT-100 Vision systems at an annual price of approximately 10% of the system’s list price.systems. The Sentinel service program covers all parts and labor for the period of the contract and one annual preventive maintenance session that includes cooling system maintenance, high voltagehigh-voltage loop maintenance, filters and system cleaning, and system touch-ups, should they be required during the preventative maintenance session.

Through our Sentinel service program, weWe also provide turn-keyturnkey pre-and post-sale services that include the following:

Consumables

We sell disposable lead shielding replacements, disposable radiation safety items, such as aprons and eye shields, and disposable applicator tips, which are used to treat various sized lesions and different areas of the body.

Competition

The medical device industry is highly competitive and subject to rapid technological change and is significantly affected by new product introductions and market activities of other participants. Our currently marketed products, and any future products we commercialize, will compete against healthcare providers who use traditional surgical treatment options, such as Mohs surgery, as well as medical device companies that offer other treatment options for the conditions our products are designed to treat. As of December 31, 2016,2019, we havehad three primary medical device company competitors:

Xstrahl Medical is an engineering company focusedprimarily focuses on industrialclinical and research x-ray therapy devices.devices and solutions. We believe most of Xstrahl Medical’s installed base is comprised of legacy orthovoltage machines made up of higher energy devices located in Europe.

Both Xoft and Elekta offer products that are considered Electronic Brachytherapy (“eBx”) devices. Due to this classification, both companies may face challenges in the U.S. and certain other international markets where laws and regulations require that a radiation oncologist, medical physicist, or radiation therapist be involved with every treatment. Additionally, the CPT® Editorial Panel has established two new treatment delivery codes for eBx for 2016, including a specific skin code. Based on typical treatment practices, it appears that bothBoth eBx products also have more limited capabilities than our products as to the size of lesions that can be treated as well as the energy levels that can be used, and require expensive consumables. Furthermore, eBx products have very limited clinical studies.

Many of our current and potential competitors have significantly greater financial, technical, marketing and other resources than we do and may be able to devote greater resources to the development, promotion, sale and support of their products. Our competitors may also have more extensive customer bases and broader customer relationships than we do, including relationships with our potential customers. In addition, many of these companies and healthcare providers have longer operating histories and greater brand recognition than we do. Because of the size of the skin cancer treatment marketmarkets and the high growth profile of the segmentsproducts in which we compete, we anticipate thatother companies willmay dedicate significant resources to developing competing products. Additionally, we may also face competition from smaller companies that have developed or are developing similar technologies for our addressable markets. We believe that the principal competitive factors in our markets include:

We may be unable to compete effectively against our competitors in regard to any one or allmore of these factors.areas. Our ability to compete effectively will depend on the acceptance of our products by dermatologists, radiation oncologists, hospitals and patients, and our ability to achieve better clinical outcomes than products developed by our existing or future competitors. In addition, certain of our competitors could use their superior financial resources to develop products that have features or clinical outcomes similar or superior to our products, which would harm our ability to successfully compete.

Sales and Marketing

We focus mainly on two primary markets, private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multi-tier sales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multi-tier sales model uses a direct sales force (currently 18 people)in the U.S., as well as international dealers and distributors.

Our dermatology market sales are directed by Stephen Cohen, our Executive Vice President, Strategic Initiatives and Dermatology, capitalizing on his prior experience in executive capacities at Technicare (now Johnson & Johnson), Diasonics, and Xoft. Our direct sales force for radiation oncology is led by Richard Golin, our Executive Vice President of Sales, Oncology and Dermatology, who has prior experience in sales at Toshiba Medical Systems, Siemens, and Hologic. We plan to continue selling and marketing our products to both the dermatology and radiation oncology markets concurrently.

Dermatology Market

Private dermatology practices in the U.S. represent the point of entry for most non-melanoma skin cancer patients. We believe the SRT-100 offers dermatologists a competitive advantage by allowing them to retain patients for the treatment of non-melanoma skin cancer, rather than referring them out to specialists for Mohs surgery or other radiation procedures. In addition to non-melanoma skin cancers, our FDA-approved indications include, among others, keloids, Kaposi’s Sarcoma, Actinic Keratosis, Metatypic Carcinoma, Cutaneous Appendage Carcinoma and other malignant skin tumors. Our SRT-100 is currently being used by over 100 U.S. dermatology practices in the treatment of keloids. Since our clearance in China in July 2017, it is also being used to treat keloids in China. We are continuing to drive our research and development to expand our indications into new areas of treatment.treatment, including psoriasis.

Radiation Oncology Market

For licensed radiation oncologists in the U.S., we believe the SRT-100 offers a simpler, faster method of treatment with a better overall patient experience. Our SRT-100 system offers oncologists the ability to free up more expensive radiation equipment, such as linear accelerators, for more complex procedures while providing patients with effective, non-invasive treatment options for non-melanoma skin cancer. Our Sculptura system has the potential to give surgeons and radiation oncologists at hospitals and cancer centers the ability to eliminate weeks of post-operative radiation treatments that patients have to undergo after surgery and also result in similar or better outcomes to current radiation treatments today, with much less collateral damage. Sculptura has several exclusive features, including 3D Beam Sculpting™ and respiratory motion tracking to the embedded image guidance and treatment area illumination.

Other Markets

As of December 31, 2016, weWe also believe that both plastic and general surgery markets present growth opportunities for our product offerings. With FDA clearance to treat keloids through superficial radiation therapy, many plastic surgeons are recognizing the opportunity to be able to provide an effective treatment solution for this benign tumor. Additionally, we believe that plastic surgeons view the non-melanoma skin cancer market as a growth opportunity that can supplement their existing services. We believe there is an opportunity to also provide superficial radiation therapy in a prophylactic manner for various surgical procedures to reduce the formation of keloids. Within the new healthcare reform environment, superficial radiation therapy can provide hospitals and surgery centers with a direct measurable impact on clinical outcomes for certain procedures, including joint replacement procedures, bypass surgery, and OBGYN/C-section procedures, among others.

Global Focus

As of December 31, 2016,2019, we havehad an installed base of over 270471 units in 1718 countries. Our customer list includes leading cancer centers, dermatology practices, hospitals and plastic surgery clinics, which we believe further validates our targeted marketing approach led by our direct sales teams and our global distribution partners.

Manufacturing and Supply

We currently use a third partyparties located in the U.S. to manufacture our products. In July 2010, we entered into a manufacturing agreement with RbM Services, LLC (“RbM”) pursuant to which RbM agreed to manufacture our SRT-100 products based on an annual 12-month sales forecast and rolling six-month sales forecast. Weproducts. Under this agreement, we pay a fixed price per unit, under the terms of this agreement, subject to annual adjustments due to changes in the costscost of materials. The initial term of this agreement was three years with successive one-year renewals thereafter. We continue to do business with RbM, although we or RbM may terminate the agreement withupon 90 days’ written notice or upon at least 60 days’ notice prior to the end of each additional one-year renewal period. We believe our third party manufacturer meets FDA, International Organization for Standardization, or ISO, and other quality standards. We maintain internal policies, procedures and supplier management processes to ensure that our third party manufacturer is meeting applicable quality standards. To date, we have not experienced any difficulty in locating and obtaining the materials necessary to meet the demand for our products, and we believe manufacturing capacity is sufficient to meet global market demand for our products for the foreseeable future.

We believe this third party manufacturing relationship initially allowed us to work with a supplier that has well-developed specific competencies while minimizing our capital investment, controlling costs and shortening cycle times, all of which we believe allowed us to compete with our competitors. However, we are in the process of adding other third party manufacturers and exploring the possibility of reducing our reliance on third party manufacturers by bringing certain manufacturing functions in-house, which could include the acquisition of equipment and other fixed assets or the acquisition or lease of a manufacturing facility.

We have a single preferred supplier for the x-ray tubes and other major components used in our products. We believe our preferred supplier has asuppliers have superior product;products; however, we also believe that the products of alternate suppliers would be adequate for our products. WeAlthough we generally do not have a contractual relationship with our preferred supplier; however,suppliers, we do not anticipate any material disruptions to our supply of x-ray tubes. Adequate x-ray tubesmajor components. We believe that adequate supplies of major components are readily accessible from alternate suppliers.

Intellectual Property

We actively seek to protect the intellectual property that we believe is important to our business, including seeking and maintaining patents that cover our products. We also rely on trademarks to build and maintain the integrity of our brand.

We own two issued U.S. patents, which expire in 2025.patents. Our patents pertain to technology in the specialized field of superficial radiotherapy treatment. The following patents were issued between August 2007 and September 2008 and were assigned to us when we acquired the technology from Topex. Topex:

We also rely on trade secrets and other unpatented proprietary rights to develop and maintain our competitive position. We seek to protect our unpatented proprietary rights through a variety of methods, including confidentiality agreements with employees, consultants and others who may have access to our proprietary information. We also require our employees to execute invention assignment agreements with respect to inventions arising from their employment.

We acquired the photon x-ray low energy or superficial x-ray therapy system, dubbed the SRT-100 and developed a next generation system — the SRT-100 Vision, which are each designed specifically to treat skin cancer and keloids as an alternative to surgery. Since first introduced in May 2007 by Topex, over 200,000 patients have been successfully treated with the SRT-100 system. The treatment of keloids has now begun at several sites throughout the world, including the U.S. and China. We are in the process of authoring and preparing additional forward-looking patents.

No patents or trademarks may ever be issued or be registered fromas a result of our pending or future applications for such intellectual property. Even if any such patents or trademarks are respectivelyultimately issued or registered, they, or any of our other intellectual property, may not provide us with any meaningful protection or competitive advantage. Our intellectual property could be challenged, invalidated, circumvented, infringed or misappropriated. In addition, third parties have claimed, and in the future may claim, that we, our customers, licensees or other parties indemnified by us are infringing upon their intellectual property rights.

Government Regulation

Our business is subject to extensive federal, state, local and foreign laws and regulations, including those relating to the protection of the environment, health and safety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of subjective interpretations. In addition, these laws and their interpretations are subject to change, or new laws may be enacted. Both federal and state governmental agencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that we have structured our business operations and relationships with our customers and suppliers to comply with all applicable legal requirements. However, it is possible that governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations that are most relevant to our business. For the years ended December 31, 20162019 and 2015,2018, we incurred approximately $697,000$1,576,000 and $330,000,$1,039,000, respectively, in expenses related to regulatory compliance and quality standards.

U.S. Food and Drug Administration (FDA)FDA Regulation of Medical Devices

The Federal Food, Drug and Cosmetic Act, or FDCA, and FDA regulations establish a comprehensive system for the regulation of medical devices intended for human use. Our products include medical devices that are subject to these, as well as other federal, state, and local laws and regulations. FDA is responsible for the overall enforcement of quality, regulatory and statutory requirements governing medical devices. Our regulated medical devices include our SRT-100SRT product line.line and Sculptura.

FDA classifies medical devices into one of three classes — Class I, Class II, or Class III — depending on their level of risk and the types of controls that are necessary to assure device safety and effectiveness. The class assignment determines the type of premarketing submission or application, if any, that will be required before marketing in the U.S. Our devices are Class II devices under the FDA’s classification system.

Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially distributed in the U.S. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA. With the enactment of the Food and Drug Administration Safety and Innovation Act, or the FDASIA, the availability of a de novopathway was facilitated for certain low- to moderate-risk devices that do not qualify for the 510(k) pathway due to the absence of a predicate device.

510(k) pathway

As of December 31, 2016,2019, all of our products arewere subject to the 510(k) requirement or are exempt from the 510(k) requirement. Three 510(k) clearances were issued to Sensus in 2019 for the Sculptura system and related components for the balloon applicator and treatment planning software. We have previously received FDA 510(k) clearances for our SRT-100, SRT-100 Vision, and SRT-100+ products.

The 510(k) review process compares a new device to aan existing legally marketed device. Through the 510(k) process, the FDA determines whether athe new medical device is “substantially equivalent” to athe existing legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed new device: (a) has the same intended use as the predicate device; (b) has the same or similar technological characteristics;characteristics as the predicate device; (c) thehas supporting information submitted in the 510(k) demonstratesapplication demonstrating that the proposed device is as safe and effective as the predicate device; and (d) the proposed device does not raise different questions of safety and effectiveness than the predicate device.

To obtain 510(k) clearance, we must submit a 510(k) application containing sufficient information and data to demonstrate that our proposed device is substantially equivalent to a legally marketed predicate device. This data generally includes non-clinical performance testing (e.g., software validation, bench testing electrical safety testing), but may also include clinical data. Typically, it takes approximately four months for the FDA to complete its review of a 510(k) submission; however, it can take significantly longer, and clearance is never assured. During its review of a 510(k), submission, the FDA may request additional information, including clinical data, which may significantly prolong the review process. After completing its review of a 510(k), submission, the FDA may issue an order, in the form of a letter, that finds the device to be either (1) substantially equivalent and states thatto the predicate device and can be marketed in the U.S., or (2) not substantially equivalent to the predicate device and states that device cannot be marketed in the U.S. Depending upon the reasons forthat the FDA finds the new device to not be substantially equivalent finding,to the predicate device, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization. A new medical device for which there is no substantially equivalent device is automatically designated a Class III device. Depending on the nature of the new device, the manufacturer may askrequest the FDA to make a risk-based determination of the new device and to reclassify it inas a Class I or Class II.II device. This process is referred to as the de novo process. If the FDA agrees, the new device will be reassigned to the appropriate other class. If the FDA does not agree, the manufacturer will have tomust submit a PMA. We have received FDA clearances for our SRT-100 and SRT-100 Vision.PMA prior to commercialization.

After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a major change in its intended use, including significant modifications to any of our products, requires submission and clearance of a new 510(k). clearance. The FDA relies on each manufacturer to make and document this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. We have made and plan to continue to make minor product enhancements that we believe do not require new 510(k) clearances. However, we expect to confer with the FDA on planned changes that may require a special, abbreviated or traditional 510(k) submission. If the FDA disagrees with our determination regarding whether a new 510(k) clearance was required for these modifications, we may need to cease marketing or recall the modified device. The FDA may also subject us to other enforcement actions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.

Premarket approval pathway

As of December 31, 2016,2019, we dodid not market any devices that arewere subject to PMA requirements. Unlike the comparative standard of the 510(k) pathway, the PMA approval process requires an independent demonstration of the safety and effectiveness of a device.device before the device can be commercialized. PMA is the most stringent type of device marketing application required by FDA. PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the device is safe and effective for its intended use(s).use. A PMA application generally includes extensive information about the device, including the results of clinical testing conducted onwith the device and a detailed description of the manufacturing process.

After a PMA application is accepted for review, the FDA begins an in-depth review of the submitted information. FDA regulations provide 180 days to review the PMA and make a determination; however, in reality, the review time is normallytypically longer (e.g., 1 – 3 years). During this review period, the FDA may request additional information or clarification of information already provided. Also during the review period, an advisory panel of experts from outside of the FDA may be convened to review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that the device is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the manufacturing facility to ensure compliance with the Quality System Regulation, or QSR, which imposes comprehensive development, testing, control, documentation and other quality assurance requirements for the design and manufacturing of a medical device.

Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information is needed), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A company may not market a device subject to PMA review cannot be marketed until the FDA issues an order approving the PMA. As part of a PMA approval, the FDA may impose post-approval conditions intended to ensure the continued safety and effectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinical data. Failure to comply with the conditions of approval can result in materially adverse enforcement action, including withdrawal of the approval.

Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before being implemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’s time for review of a PMA supplement vary depending on the nature of the modification.

Clinical trials

Clinical trials of medical devices in the U.S. are governed by the FDA’s Investigational Device Exemption regulation, in accordance with 21 CFR, Part 812. This regulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial, submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control the disposition of the investigational device, submit required reports, etc.

Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing, mitigating or treating disease or otherwise preventing impairment of human health) require FDA and Institutional Review Board approval prior to starting the trial. FDA approval is obtained through submission of an Investigational Device Exemption application. Clinical trials of non-significant risk devices (i.e. devices that do not meet the regulatory definition of a significant risk device) only require Institutional Review Board approval before starting. The clinical trial sponsor is responsible for making the initial determination of whether a clinical study is significant risk or non-significant risk; however, a reviewing Institutional Review Board or the FDA may review this decision and disagree with the determination.

An Investigational Device Exemption application must be supported by appropriate data, such as performance data, animal and laboratory testing results, showing that it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of an Investigational Device Exemption will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it on hold or terminate it if, among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.

As noted above, the FDA may require a company to collect clinical data on a device in the postmarketpost-market setting. The collection of such data may be required as a condition of PMA approval. FDA also has the authority to order, via a letter, a postmarketpost-market surveillance study, in accordance with 21 CFR, Part 822, for certain devices at any time after they have been cleared or approved. We do not expect to launch clinical trials subject to the Investigational Device Exemption regulations for future products. Also, our products are not currently subject to any required postmarket

post-market surveillance studies.

Pervasive and continuing FDA regulation

After a device is entered into commerce in the U.S., regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply. These include:

The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcement action by FDA, which may include, but is not limited to, the following sanctions:

We are subject to unannounced establishment inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance with applicable state public health regulations. These inspections may include our suppliers’ facilities.

International

International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. In order to market our products in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries.regulations. The time required to obtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ. The European Union/European Economic Area, or EU/EEA, requires a CE conformity mark in order to market medical devices. Many other countries, such as Australia, India, New Zealand, Pakistan and Sri Lanka, accept CE or FDA clearance or approval, although others, such as China, Brazil, Canada and Japan require separate regulatory filings.

In the EEA, our devices are required to comply with the essential requirements of the EU Medical Devices Directive (93/42/EEC). Compliance with these requirements entitles us to affix the CE marking of conformity to our medical devices, without which they cannot be commercialized in the EEA. To demonstrate compliance with the essential requirements and obtain the right to affix the CE marking of conformity we must undergo a conformity assessment procedure, which varies according to the type of medical device and its classification. Except for low risk medical devices (Class I), where the manufacturer can issue an EC Declaration of Conformity based on a self-assessment of the conformity of its products with the essential requirements of the Medical Devices Directive, a conformity assessment procedure requires the intervention of a Notified Body, which is an organization accredited by a Member State of the EEA to conduct conformity assessments. The Notified Body would typically audit and examine the quality system for the manufacture, design and final inspection of our devices before issuing a certification demonstrating compliance with the essential requirements. Based on this certification we can draw up an EC Declaration of Conformity which allows us to affix the CE mark to our products.

Further, the advertising and promotion of our products in the EEA is subject to the laws of individual EEA Member States implementing the EU Medical Devices Directive, Directive 2006/114/EC concerning misleading and comparative advertising, and Directive 2005/29/EC on unfair commercial practices, as well as other EEA Member State laws governing the advertising and promotion of medical devices. These laws may limit or restrict the advertising and promotion of our products to the general public and may impose limitations on our promotional activities with healthcare professionals.

We have obtained approval to sell our products in Australia, Canada, China, Europe, China,India, Israel, Mexico, Russia, South Africa, South Korea, and RussiaTaiwan, and we are currently seeking approval in several other counties.countries.

Sales and Marketing Commercial Compliance

Federal anti-kickback laws and regulations prohibit, 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, or the purchase, order or recommendation of, any good or service paid for under federal healthcare programs such as the Medicare and Medicaid programs. Possible sanctions for violation of these anti-kickback laws include monetary fines, civil and criminal penalties, exclusion from Medicare and Medicaid programs and forfeiture of amounts collected in violation of such prohibitions.

In addition, federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government, or knowingly making, or causing to be made, a false statement to get a false claim paid. Off-label promotion has been pursued as a violation of the federal false claims laws. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although surgeons are permitted to use medical devices for indications other than those cleared or approved by FDA based on their medical judgment, we are prohibited from promoting products for such off-label uses. Additionally, the majority of states in which we market our products have similar anti-kickback, false claims, anti-fee splitting and self-referral laws, which may apply to items or services reimbursed by any third party payor, including commercial insurers, and violations may result in substantial civil and criminal penalties.

To enforce compliance with the federal laws, the U.S. Department of Justice, or DOJ, has increased its scrutiny of interactions between healthcare companies and healthcare providers which has led to an unprecedented level of investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing with investigations can be time- and resource-consuming. Additionally, if a healthcare company settles an investigation with the DOJ or other law enforcement agencies, the company may be required to agree to additional compliance and reporting requirements as part of a consent decree or corporate integrity agreement.

The U.S. and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry, including increased U.S. government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever a governmental authority concludes that we are not in compliance with applicable laws or regulations, that authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain or seize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees and can recommend criminal prosecution. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of devices we distribute.

Additionally, the commercial compliance environment is continually evolving in the healthcare industry as some states, including California, Massachusetts and Vermont, mandate implementation of corporate compliance programs, along with the tracking and reporting of gifts, compensation and other remuneration to physicians. The Affordable Care Act also imposes reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed to prescribers and other healthcare providers. Device manufacturers are also required to report and disclose any investment interests held by physicians and their family members during the preceding calendar year. Failure to submit required information may result in civil monetary penalties of 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. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictions with different compliance or reporting requirements increases the possibility that a healthcare company may run afoul of one or more of the requirements.

Healthcare Fraud and Abuse

Healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursed under Medicare, Medicaid or most other federally funded healthcare programs. The federal Anti-Kickback Statute prohibits unlawful inducements for the referral of business reimbursable under federally funded healthcare programs, such as remuneration provided to physicians to induce them to use certain tissue products or medical devices reimbursable by Medicare or Medicaid. The Anti-Kickback Statute is subject to evolving interpretations. For example, the government has enforced the Anti-Kickback Statute to reach large settlements with healthcare companies based on sham consultant arrangements with physicians. The majority of states also have anti-kickback laws which establish similar prohibitions that may apply to items or services reimbursed by any third party payor, including commercial insurers. Further, recently enacted amendments to the Affordable Care Act, among other things, amend the intent requirement of the federal anti-kickback and criminal healthcare fraud statutes. A person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act provides that 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 statutes. If a governmental authority were to conclude that we are not in compliance with applicable laws and regulations, we and our officers and employees could be subject to severe criminal and civil penalties including, for example, exclusion from participation as a supplier of product to beneficiaries covered by Medicare or Medicaid. In addition to the Anti-Kickback Statute, the federal physician self-referral statute, commonly known as the Stark Law, prohibits physicians who have a financial relationship with an entity, including an investment, ownership or compensation relationship, from referring Medicare patients for designated health services, which include clinical pathology services, unless an exception applies. Similarly, entities may not bill Medicare or any other party for services furnished pursuant to a prohibited referral. Many states have their own self-referral laws as well, which in some cases apply to all third party payors, not just Medicare and Medicaid. If a governmental authority were to conclude that we are not in compliance with the Stark Law or state self-referral laws and regulations, our pathology laboratory business could be subject to severe financial consequences, including the obligation to refund amounts billed to third party payors in violation of such laws, civil penalties and potentially also exclusion from participation in government healthcare programs like Medicare and Medicaid. The Stark Law often is enforced through lawsuits brought under the Federal False Claims Act, violations of which trigger significant monetary penalties and treble damages.

Additionally, the civil False Claims Act prohibits knowingly presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S. government. Actions under the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of the government. Violations of the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the False Claims Act, and the accompanying threat of significant liability, in its investigations of healthcare providers and suppliers throughout the country for a wide variety of Medicare billing practices, and has obtained multi-million and multi-billion dollar settlements in addition to individual criminal convictions. Given the significant size of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ and suppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws.

Health Information Privacy

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their respective implementing regulations, impose requirements on certain covered healthcare providers, health plans and healthcare clearinghouses, known as covered entities, as well as their business associates that perform services for them that involve individually identifiable health information. The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards with respect to the use and disclosure of protected health information by covered entities and their business associates, in addition to setting standards to protect the confidentiality, integrity and security of protected health information.

We have implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and security regulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, we are required to comply with both federal privacy and security regulations and varying state privacy and security laws. In addition, for healthcare data transfers from other countries relating to citizens of those countries, we must comply with the laws of those other countries. The federal privacy regulations restrict our ability to use or disclose patient identifiable laboratory data, without patient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policy purposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties for wrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines and penalties. If we do not comply with existing or new laws and regulations related to protecting the privacy and security of health information, we could be subject to monetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may be subject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, we could incur damages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other private personal information. If we were to experience a breach of protected health information, we could be subject to significant adverse publicity in addition to possible enforcement sanctions and civil damages lawsuits. Finally, we may be required to incur additional costs related to ongoing HIPAA compliance as may be necessary to address evolving interpretations and enforcement of HIPAA and other health information privacy and security laws, the enactment of new laws or regulations, emerging cybersecurity threats and other factors.

Research and Development

Research and development costs relate to our products under development and quality and regulatory costs and are expensed as incurred. During the years ended December 31, 20162019 and 2015,2018, we incurred research and development expense of approximately $1.8$6.4 million and $1.5$6.3 million, respectively. We expectMost of the amountincrease in R&D spending in 2019 was related to the final development and production ramp-up of our researchSculptura™, a modulated robotic brachytherapy radiation oncology system that provides targeted directional anisotropic radiation therapy (ART) and development, or R&D, expense to increase asbrachytherapy, for which we continue to innovatefiled a 510(k) application with the U.S. Food and introduce new productsDrug Administration (FDA) in December 2017 and technologies.received FDA clearance in February 2019.

Employees

As of December 31, 2016,2019, we had 3753 employees, allincluding 46 in the U.S. and seven in Israel. None of our employees areis represented by a labor union or covered by a collective bargaining agreement. We consider our relationship with our employees to be good.

An investment in our common stock contains a high degree of risk. You should consider carefully the risks and uncertainties described below before making an investment decision. Our business could be harmed if any of these risks, as well as other risks not currently known to us or that we currently deem immaterial, materialize. The trading price of our common stock could decline due to the occurrence of any of these risks, and you may lose all or part of your investment. In assessing the risks described below, you should also refer to the other information contained in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes and schedules, and other filings with the SEC. This Annual Report on Form 10-K also contains forward-looking statements that involve risks and uncertainties that could cause our actual results to differ materially from those discussed in this Annual Report on Form 10-K. These risks and uncertainties include the following:

Risks Related to our Business

We have a history of net losses. If we do not consistently achieve profitability, our financial condition and the value of our common stock could suffer.

We have a history of net losses. Our historical losses from inception through December 31, 20162019 totaled approximately $7.8$15.2 million. If our revenue grows more slowly than currently anticipated, or if operating expenses are higher than expected, we may be unable to consistently achieve profitability, our financial condition will suffer, and the value of our common stock could decline. Even if we are successful increasing our sales, we may incur losses in the foreseeable future as we continue to research and develop and seek regulatory approvals for our products. If sales revenue from any of our currently cleared products or any additional products that receive marketing clearance from the FDA or approval from other regulatory authorities in the future is insufficient, or if our product development is delayed, we may be unable to achieve profitability. Furthermore, even if we are able to achieve profitability, we may be unable to sustain or increase such profitability on a quarterly or annual basis, which would significantly reduce the value of our common stock.

If third-party payors do not provide coverage and adequate reimbursement for the use of our products, it is unlikely that our products will be widely used, and our revenue will be negatively impacted.

In the U.S., the commercial success of our existing products and any future products will depend, in part, on the extent to which governmental payors at the federal and state levels, including Medicare and Medicaid, private health insurers and other third-party payors provide coverage for and establish adequate reimbursement levels for procedures using our products. The existence of coverage and adequate reimbursement for our products and related procedures by government and private payors is critical to market acceptance of our existing and future products. Neither hospitals nor physicians are likely to use our products if they do not receive adequate reimbursement payments for the procedures using our products.

Some private payors in the U.S. may base their reimbursement policies on the coverage decisions determined by the Center of Medicare and Medical Services, or CMS, which administers the Medicare program and works in partnership with state governments to administer the Medicaid program. Others may adopt different coverage or reimbursement policies for procedures performed using our products, while some governmental programs, such as Medicaid, have reimbursement policies that vary from state to state, some of which may not pay for our products in an amount that supports our selling price, if at all. A Medicare national or local coverage decision denying coverage for any of the procedures performed with our products could result in private and other third-party payors also denying coverage. Medicare (part(Part B) and a number of private insurers in the U.S. currently cover and pay for both non-melanoma skin cancer and keloid treatments using the SRT-100. A withdrawal, or even contemplation of a withdrawal, by CMS, Medicaid or private payors of reimbursements, or any other unfavorable coverage or reimbursement decisions by government programs or private payors, could have a material adverse effect on our business.

Reimbursement systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtained on a country-by-country basis. In many international markets, a product must be approved for reimbursement before it can be cleared for sale in that country. Further, many international markets have government-managed healthcare systems that control reimbursement for new devices and procedures. In most markets there are private insurance systems as well as government-managed systems. Our products may not be considered cost-effective by international third-party payors or governments managing healthcare systems. Furthermore, reimbursement may not be available or, if available, third-party payors’ reimbursement policies may adversely affect our ability to sell our products profitably. If sufficient coverage and reimbursement are not available for our current or future products, in either the U.S. or internationally, the demand for our products and, consequently, our revenues will be adversely affected.

Substantially all of our revenue is generated from the sale of our SRT-100 and related products, and any decline in the sales of these products or failure to gain market acceptance of these products will negatively impact our business, financial condition and results of operations.

We have focused heavily on the development and commercialization of a limited number of products for the treatment of non-melanoma skin cancer and other skin conditions with superficial radiotherapy. From our inception in 2010 through December 31, 2016, substantially all2019, most of our revenue has been derived from sales of our SRT-100 product line and related services and ancillary products. WeAlthough we intend to introduce new products, we expect substantially allmost of our 2020 revenue to be derived from or related to sales of our SRT-100 product line for the foreseeable future. Besides differentiated or enhanced versions of the SRT-100 and ancillary products, we are not currently developing or otherwise investing in any other product.line. If we are unable to achieve and maintain significantly greater market acceptance of superficial radiotherapy for treatment of non-melanoma skin cancer and other skin conditions, or if we do not achieve sustained positive cash flow, then we will be severely constrained in our ability to fund our operations. In addition, if we are unable to market our SRT-100 product line and ancillary products as a result of a quality problem, shortage of components required to for assembly, failure to maintain or obtain regulatory approvals, unexpected or serious complications or other unforeseen negative effects related tofrom the use of the SRT-100 product line and ancillary products, we would lose our only source of revenue, and our business, financial condition and results of operations will be adversely affected.

We may be unable to manufacture our products in quantities sufficient to meet existing demand levels, which would hinder our ability to effectively commercialize our products and increase revenues.

The manufacture of medical devices requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls, from us and our key suppliers, to scale up the production process to manufacture sufficient quantities at high volume and with satisfactory production yields. Manufacturers of medical devices often encounter difficulties in production, particularly when scaling up initial production. These problems include difficulties with production costs and yields, quality control and assurance, and shortages of qualified personnel, as well as compliance with strictly enforced federal, state and foreign regulations.

In July 2010, we entered into a manufacturing agreement with an unrelated third partyRbM for the manufacturing and production of the SRT-100 in accordance with our specifications. We continue to do business with the manufacturerRbM pursuant to this agreement, although we or the manufacturerRbM may terminate the agreement withupon 90 days’ written notice or upon at least 60 days’days��� notice prior to the end of each additional one-year renewal period. As discussed elsewhere in this Annual Report on Form 10-K, we are in the process of adding another contract manufacturer and are exploring the possibility of using a portion of the proceeds of our IPO to begin reducing our reliance on third party manufacturers by bringing certain manufacturing capabilities in-house. However, if eventually implemented, our plan to bring the manufacturing function in-house may not be successful and we may be unable to maintain a relationship with our current manufacturer or establish a relationship with another manufacturer on favorable terms, if at all.

Consequently, we may not, with our third party suppliers, be able to continue to efficiently manufacture our products in sufficient quantities to meet projected demand or to establish sufficient worldwide inventory to fully support our distribution network. Any of these results could cause us to be unable to effectively commercialize our products or increase revenue, adversely affecting our business, financial condition, results of operations and the value of our common stock.

We have a single preferred supplier for the x-ray tubes and other major components used in our products and the loss of this preferred supplier could adversely affect us.

We have a single preferred suppliersuppliers for the x-ray tubes and other major components used in our products, althoughproducts. Although other suppliers exist in the market.market, we believe that our preferred supplier’s products are of a superior quality. The loss of thisthese preferred supplier,suppliers, or their inability to supply us or our third party manufacturer with adequate components could hinder our ability to effectively produce our products to meet existing demand levels, especially if we were unable to timely procure x-ray tubesthem from another supplierother suppliers in the market, which could adversely affect our ability to commercialize our products and increase our revenues.

We may be unable to retain and develop our U.S. sales force and non-U.S. distributors, which would adversely affect our ability to meet our revenue targets and other goals.

As we launch products, increase current sales efforts and expand into new geographies,geographic areas, we will need to retain, grow and develop our direct sales personnel, distributors and agents. There is significant competition for sales personnel experienced in relevant medical device sales. In addition, the training process is lengthy because it requires significant education for new sales representatives to achieve an acceptable level of clinical competency with our products. Upon completion of training, sales representatives typically require lead time in the field to develop or expand 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 the sales representatives do not achieve the productivity levels expected, our revenue will not grow as expected, and our financial performance will suffer.

In addition, we may not succeed in entering into and maintaining productive arrangements with an adequate number of distributors outside of the U.S. that are sufficiently committed to selling our products in international markets. The establishment and maintenance of a distribution network is expensive and time consuming. Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as we expect them to, commit the necessary resources to effectively market and sell our products, or ultimately succeed in selling our products. Moreover, if our sales force and distributors are unable to attract and retain new customers, we may be unable to achieve our expected growth, and our business could suffer.

Furthermore, some of our distributors may market or sell the products of our competitors. In these cases, the competitors may have the ability to influence the products that our distributors choose to market and sell, for example, by offering higher commission payments, or by convincing the distributors to terminate their relationships with us, carry fewer of our products or reduce their sales and marketing efforts for our products. Any of the foregoing would hinder our ability to meet our revenue targets and other goals.

The future worldwide demand for our current products and our future products is uncertain. Our current products and our future products may not be accepted by hospitals, physicians or patients, and may not become commercially successful.

Physicians and hospitals may not perceive the benefits of our products and may be reluctant or unwilling to adopt our products as a treatment option, particularly in light of existing treatment options, such as Mohs surgery or high dose rate brachytherapy. Additionally, physicians and hospitals may not be aware of the significant advances in technology associated with superficial radiation therapy compared to older technology that was previously used with orthovoltage. While we believe that our products are an efficient and less invasive alternative to other treatments of non-melanoma skin cancer and other skin conditions, physicians who are accustomed to using other modalities to treat patients with either non-melanoma skin cancer, keloids or other skin conditions may be reluctant to adopt broad use of our superficial radiotherapy products.

We must grow markets for our products through physician education and awareness programs. Publication in peer-reviewed medical journals of results from studies using our products will be an important consideration in their adoption by physicians and in reimbursement decisions of third-party payors. The process of publication in leading medical journals is subject to a peer-review process. Peer reviewers may not consider the results of studies of our products and any future products sufficiently novel or worthy of publication. Failure to have studies of our products published in peer reviewed journals may adversely affect adoption of our products.

Educating physicians and hospitals on the benefits of our products and advancements in superficial radiation technology requires a significant commitment by our marketing team and sales organization. Our products may not become widely accepted by physicians and hospitals. If we are unable to educate physicians and hospitals about the advantages of our products, do not achieve significantly greater market acceptance of our products, do not gain momentum in our sales activities, or fail to significantly grow our market share, we will be unable to grow our revenue, and our business and financial condition will be adversely affected.

We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are able to develop and market products that are more effective, less costly, easier to use or otherwise more attractive than any of our products, our business will be adversely impacted.

The medical device industry is highly competitive and subject to technological change. In the arena for technology and products for use in the treatment of non-melanoma skin cancer and other skin conditions, we have three primary competitors, one of which operates in the superficial radiotherapy space largely in the European market, and the other two of which operate in the brachytherapy space in both the U.S. and internationally. While we believe our SRT-100 and related products currently have certain competitive advantages over the products offered by these competitors, our success depends, in part, upon our ability to maintain this competitive position. If these competitors improve their existing products, develop new products, or expand their operations, we may be unable to maintain our competitive advantages over these competitors.

Furthermore, new competitors, including companies larger than us, may enter the market in the future and may offer products with similar or alternative functionalities. These companies may enjoy several advantages relative to us, including:

Hospitals, physicians and investors may not view our products as competitive with other products that are marketed and sold by new competitors, including much larger and more established companies. Our competitors may develop and patent processes or products earlier than we do, obtain regulatory clearance or approvals for competing products more rapidly than us or develop more effective, more convenient or less expensive products or technologies that render our technology or products obsolete or less competitive. If our existing or new competitors are more successful than us in any of these matters, our business may be harmed.

Our customers are concentrated in the U.S. and China, and economic difficulties or changes in the purchasing policies or patterns of our customers in these countries could have a significant impact on our business and operating results.

Substantially allmost of our 20162019 and 20152018 sales were made to customers located in the U.S. However in previous years significant sales were made to customers located in Israel and China. For the years ended December 31, 20162019 and 2015,2018, approximately 11%3% and 14%1%, respectively, of our product sales were to Chinese customers and approximately 4% and 1%, respectively to Israeli customers, with substantiallya substantial portion of the remainder of our sales to customers in the U.S. Additionally, a single customer in the U.S. accounted for approximately 68% and 71% of revenues for the years ended December 31, 2019 and 2018, respectively. Because of our geographic and customer concentrations, our revenue could fluctuate significantly due to changes in economic conditions, the use of competitive products, or the loss of, reduction of business with, or less favorable terms within, these countries.countries or this customer. A reduction or delay in orders for our products from these countries and this customer could materially harm our business and results of operations.operations, including any adverse impact of the coronavirus epidemic

Our future success depends on our ability to develop, receive regulatory approval for, and introduce new products or product enhancements that will be accepted by the market in a timely manner, and if we do not do so, our results of operations will suffer.

It is important to our business that we continue to build a pipeline of product offerings for the treatment of non-melanoma skin cancer and other skin conditions to remain competitive. Consequently, our success will depend in part on our ability to develop and introduce new products. However, we may be unable to successfully maintain our regulatory clearance for existing products, or develop, obtain and maintain regulatory clearance or approval for product enhancements, or new products, or these products may not be accepted by physicians or the payors who financially support many of the procedures performed with our products.

The success of any new product offering or enhancement to an existing product will depend on several factors, including our ability to:

If we do not develop new products or product enhancements and obtain regulatory approval in time to meet market demand, if there is insufficient demand for these products or enhancements, or if competitors introduce new products with enhanced functionalities that are superior to those of ours, then our results of operations will suffer.

Our products may become obsolete prior to the end of their anticipated useful lives, and we may be required to dispose of existing inventory or write off the value or accelerate the depreciation of the these assets, each which would materially and adversely impact our results of operations.

We focus on continual product innovation and product improvement. While we believe this provides a competitive edge, it also results in thecreates a risk that our products will become obsolete prior to the end of their anticipated useful lives. If we introduce new products or next-generation products prior to the end of the useful life of a prior generation, we may be required to dispose of existing inventory, or write off the value of the these assets, each of which would materially and adversely impact our results of operations.

Our success is dependent in large part on our being an early re-entrant into the market for our proprietary superficial radiotherapy systems, and if one or more competitors join us in the market, our marketing efforts and ability to compete would be materially and adversely affected.

Our success is dependent in large part on our being an early re-entrant into the market for our proprietary superficial radiotherapy systems. If one or more competitors join us in the market, the increased competition would require us to devote substantial additional resources to our marketing efforts, and our ability to compete may be severely impaired.

Our international operations subject us to certain operating risks, which could adversely impact our results of operations and financial condition.

The sale and shipment of our products across international borders, as well as the purchase of components from international sources, subjects us to U.S. and foreign governmental trade, import and export, and customs regulations and laws. Compliance with these regulations and laws is costly and exposes us to penalties for non-compliance. Other laws and regulations that can significantly impact us include various anti-bribery laws, including the U.S. Foreign Corrupt Practices Act, and anti-boycott laws, as well as export control laws. Any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways that include, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of export privileges, seizure of shipments, restrictions on certain business activities and exclusion or debarment from government contracting. Also, the failure to comply with applicable legal and regulatory obligations could result in the disruption of our shipping and sales activities. Any of the foregoing would adversely impact our results of operations and financial condition.

Our international operations and our international distributors expose us to risks inherent in operating in foreign jurisdictions. These risks include, without limitation:

If any of these events or circumstances were to occur, our sales in foreign countries would be harmed and our results of operations would suffer.

Our U.S. business could be adversely affected by changesongoing disruptions in international trade regulation.

The U.S. presidential administration that came to power in January 2017Both the Trump Administration and certain members of the U.S. Congress have indicated that they may seek to impose importation tariffs on products from certain countries such as China and Mexico and/or to impose additional taxes on imported goods generally. Certain countries have publicly stated that they would respond in-kind to any such action by the U.S. The Trump Administration recently imposed tariffs on solar panels and washing machines. Any future escalation of protectionist trade measures could increase the prices of products, components and supplies that we source internationally, as well as adversely affect our ability to sell our products in foreign markets. In addition, the Trump Administration will appointhas appointed and employemployed many new public officials into positions of authority in the U.S. Federal government dealing with the healthcare industries that may potentially have a negative impact on the prices and the regulatory pathways for certain healthcare products such as those developed, marketed and sold by us. Such changes in the regulatory pathways could adversely affect and or delay our ability to market and sell our products in the U.S. and internationally.

Our operating results may vary significantly from quarter to quarter, which may negatively impact the value of our securities.

Our quarterly revenues and results of operations may fluctuate due to the following reasons, among others:

Because of these and other related or similar factors, it is likely that in some future period our operating results will not meet expectations. Failure to meet or exceed analyst expectations could cause a decrease in the trading price of our securities.

We may be unable to attract and retain highly qualified personnel, which could adversely and materially affect our competitive position.

Our future success depends on our ability to attract and retain our executive officers and other key employees. We may be unable to attract or retain qualified management and other key personnel in the future due to the intense competition for qualified personnel among companies in the medical device business and related industries, particularly in the South Florida area where we are headquartered. The medical device industry has experienced a high rate of turnover of management personnel in recent years. Consequently, we could have difficulty attracting or retaining experienced personnel and may be required to spend significant time and expend significant financial resources in our employee recruitment and retention efforts. Many of the other medical device companies with which we compete for qualified personnel have greater financial and other resources and risk profiles different from ours. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than that which we may offer. If we are unable to attract and retain the necessary personnel to accomplish our business objectives, we may have difficulty implementing our business strategy and achieving our business objectives.

Product liability claims could damage our reputation and adversely affect our business.

The design, manufacture and marketing of medical devices each carry an inherent risk of product liability claims and other damage claims. In addition to the exposure we may have for defective products, physicians may misuse our products or use improper techniques, regardless of how well trained, potentially leading to injury and an increased risk of product liability. A product liability or other damages claim, product recall or product misuse could require us to spend significant time and money in litigation, regardless of the ultimate outcome, or to pay significant damages and could seriously harm our business.

We maintain liability insurance coverage that management believes to be reasonable based on our business and operations; however, our insurance may not be sufficient to cover all claims made against us. Our insurance policies generally must be renewed on an annual basis. We may be unable to maintain or increase insurance on acceptable terms or at reasonable costs. A successful claim brought against us in excess, or outside of, our insurance coverage could seriously harm our financial condition or results of operations.

We may be required to obtain additional funds in the future, and these funds may not be available on acceptable terms or at all.

Our operations have consumed substantial amounts of cash since inception, and we anticipate that our expenses will increase as we continue to grow our business. We may need to seek additional capital in the future. Our growth will depend, in part, on our ability to develop variations of the SRT-100 and other products, and related technology complementary to our products. Our existing financial resources, including our existing revolving line of credit, may not allow us to conduct all of the activities that we believe would be beneficial for our future growth.

We may need to seek funds in the future. Our existing revolving line of credit restricts our ability to incur certain indebtedness or permit certain encumbrances on our assets without the prior written consent of the lender. If we are unable to raise funds on favorable terms, or at all, we may not be able to support our commercialization efforts or increase our research and development activities or meet our debt and other contractual obligations, and the growth of our business may be negatively impacted. As a result, we may be unable to compete effectively.

Our cash requirements in the future may be significantly different from our current estimates and depend on many factors, including:

We may be unable to raise funds on favorable terms, or at all, and either case would materially and adversely affect our ability to implement our strategy and meet our goals.

To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders’the ownership interestinterests of our existing stockholders will be diluted, anddiluted. Moreover, the terms of newly issued securities may include liquidation or other preferences that adversely affect common stockholders’ rights. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring additional debt, making capital expenditures or declaring distributions or dividends. If we raise additional funds through collaboration and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or products or grant licenses on terms that are not favorable to us. Any of these events could adversely affect our ability to declare dividends on our common stock and to achieve our product development and commercialization goals and have a material adverse effect on our business, financial condition and results of operations.

Our revolving credit facility imposes substantial restrictions on us, some of which could hinder our ability to conduct our operations effectively or otherwise in accordance with our business plan.

In March 2013, we entered into a $3.0 millionOur revolving credit facility which was amended in March 2015 to extend the facility and to reduce the facility to $1.5 million. The maximum borrowing is limited by our eligible borrowing base, equal to 80% of eligible accounts receivable as defined in the facility agreement. On September 21, 2016, a second amendment to the credit facility extended the facility through September 21, 2017, increased the maximum borrowing to $2.0 million and expanded the eligible accounts receivable to include certain international receivables.

Under the facility agreement, we must pay monthly interest at a rate of the Prime Rate plus 0.75%, and must pay any outstanding principal and interest on or before the maturity date,. The facility is secured by all of our assets and limits the amount of additional indebtedness, restricts the sale, disposition or transfer of our assets and requires the maintenance of a certain monthly adjusted quick ratio restrictive covenant and minimum quarterly EBITDA restrictive covenant, as defined in the agreement. We were not in compliance with certain of these financial covenants as of October 31, 2015 and November 30, 2015, but we received a formal waiver from the bank in February 2016 for our noncompliance. We were in compliance as of December 31, 2016.

Additionally, the facility agreement contains a number of negative covenants that require us to seek the lender’s prior written consent in order to conduct certain activities. For example, we may not, without the prior written consent of the lender:

In the event we wish to conduct any of the foregoing activities and the lender refuses to provide its prior written consent, our ability to conduct our operations effectively and in accordance with our business plan could be materially and adversely affected.

We did not have any amounts outstanding under the revolving credit facility as of December 31, 2016.

If we fail to properly manage our anticipated growth, our business could suffer.

Our strategy involves substantial growth. If we experience periods of rapid growth and expansion, our limited personnel, operational infrastructure and other resources could be significantly strained. In particular, the possible internalization of manufacturing, and continued expansion of our direct sales force in the U.S. will require significant management, financial and other supporting resources. In addition, in order to manage expanding operations, we will need to continue to improve our operational and management controls, reporting and information technology systems and financial internal control procedures. If we are unable to manage our growth effectively, it may be difficult for us to execute our business strategy and our operating results and business could suffer. Any failure by us to manage our growth effectively could have an adverse effect on our ability to achieve our goals. To achieve our revenue goals, we must successfully increase production output to meet projected customer demand. We may be unable to increase output on the timeline anticipated, if at all. Also, we may in the future experience difficulties with production yields and quality control, component supply, and shortages of qualified personnel, among other problems. These problems could result in delays in product availability and increases in expenses. Any delay or increased expense could adversely affect our ability to increase revenues.

Cost-containment efforts of our customers, purchasing groups and governmental organizations could have a material adverse effect on our sales and profitability.

In an effort to reduce costs, many hospitals or physicians within the U.S. and abroad are members of group purchasing organizations and integrated delivery networks. Group purchasing organizations and integrated delivery networks negotiate pricing arrangements with medical device companies and distributors and offer the negotiated prices to affiliated hospitals, physicians and other members. Group purchasing organizations and integrated delivery networks typically award contracts on a category-by-category basis through a competitive bidding process. Bids are generally solicited from multiple providers with the intention of driving down pricing or reducing the number of vendors. Due to the highly competitive nature of the group purchasing organizationsorganizations’ and integrated delivery networksnetworks’ contracting processes, we may be unable to obtain or maintain contract positions with major group purchasing organizations and integrated delivery networks. Furthermore, the increasing leverage of organized buying groups may reduce market prices for our products, thereby reducing our profitability.

While having a contract with a group purchasing organizations or integrated delivery networks for a given product category can facilitate sales to members of that group purchasing organizations or integrated delivery networks, expected sales levels may not be achieved, as sales are typically made pursuant to purchase orders. Even when a provider is the sole contracted supplier of a group purchasing organization or integrated delivery network for a certain product category, members of the group purchasing organization or integrated delivery network generally are free to purchase from other suppliers. Furthermore, group purchasing organizations and integrated delivery networks contracts typically are terminable without cause by the group purchasing organizations or integrated delivery networks upon 60 to 90 days’ notice. Accordingly, even if we obtain contracts with any group purchasing organizations or integrated delivery networks, the members of these groups may choose to purchase from our competitors due to the price or quality offered by competitors, which could result in a decline in our sales and profitability.

We depend on information technology systems to operate our business and a cyber-attack or other breach of these systems could have a material adverse effect on our business.

We rely on information technology systems to process, transmit and store electronic information in our day-to-day operations. Our information technology systems could be vulnerable to a cyber-attack, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption. Any successful attacks could result in the theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information or disrupt our operations. Cyber-attacks are becoming more sophisticated and frequent, and our systems could be the target of malware and other cyber-attacks. We have invested in our systems and the protection of our data to reduce the risk of an intrusion or interruption, and we monitor our systems on an ongoing basis for any current or potential threats.

However, these measures and efforts may not prevent interruptions or breakdowns, and we may otherwise fail to maintain or protect our information technology systems and data integrity effectively. Furthermore, we may fail to anticipate, plan for or manage significant disruptions to our systems. If any of the foregoing were to occur, our competitive position could be harmed, we could lose existing customers, have difficulty preventing, detecting and controlling fraud, have disputes with customers, specialist physicians and other healthcare professionals, have regulatory sanctions or penalties imposed, incur expenses or lose revenues as a result of a data breach or theft of intellectual property or suffer other adverse consequences, any of which could have a material adverse effect on our business, results of operations, financial condition or cash flows.

The medical technology industry has experienced a significant amount of consolidation, resulting in companies with greater market presence. Health care systems and other health care companies are also consolidating, resulting in greater purchasing power for the combined companies. As a result, the disruption in the healthcare industry caused by consolidation may lead to further competition among medical device suppliers to provide goods and services, which could adversely affect our future revenues and operating income.

We may engage in acquisitions, mergers, strategic alliances, and joint ventures that could result in final results that are different than expected.

In the normal course of business, we engage in discussions relating to possible acquisitions, equity investments, mergers, strategic alliances, and joint ventures. Such transactions are accompanied by a number of risks, including the use of significant amounts of cash, potentially dilutive issuances of equity securities, incurrence of debt on potentially unfavorable terms as well as impairment expenses related to goodwill and amortization expenses related to other intangible assets, the possibility that we may pay too much cash or issue too many of our shares as the purchase price for an acquisition relative to the economic benefits that we ultimately derive from such acquisition, and various potential difficulties involved in integrating acquired businesses into our operations.

If we do not realize the expected benefits of such transactions, our financial position, results of operations, cash flows and stock price could be negatively impacted.

Risks Related to our Regulatory Environment

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

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

Additionally, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and applicable implementing regulations, impose certain requirements relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization on entities subject to the law, such as health plans, clearinghouses, and healthcare providers and their business associates. Internationally, substantially every jurisdiction in which we operate has established its own data security and privacy legal framework with which we must comply, including the Data Protection Directive 95/46/EC and national implementation of the Directive in the member states of the European Union.

Many states have also adopted laws similar to each of the above federal laws, such as anti-kickback and false claims laws, which may be broader in scope and apply to items or services reimbursed by any third-party payor, including commercial insurers, as well as laws that restrict our marketing activities with healthcare professionals and entities, and require us to track and report payments and other transfers of value, including consulting fees, provided to healthcare professionals and entities. Some states mandate implementation of compliance programs to ensure compliance with these laws. Additionally, certain states require a certificate of need prior to the installation of a radiation device, such as the SRT-100. We are also subject to foreign fraud and abuse laws, which vary by country.

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 administrative, civil and criminal penalties, damages, fines, disgorgement, individual imprisonment, contractual damages, reputational harm, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations. Any of the foregoing could adversely affect our ability to operate our business and our financial results.

Our products are subject to extensive governmental regulation that could make it more expensive and time consuming for us to introduce new or improved products.

Our products must comply with regulatory requirements imposed by the U.S. Food and Drug Administration, the U.S. Department of Health and Human Services and other governmental agencies in the U.S., and similar agencies in foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinical testing procedures, sampling activities, an extensive agency review process, and other costly and time-consuming procedures. It often takes several years to satisfy these requirements, depending on the complexity and novelty of the product. If we execute on our plans to move our manufacturing function in-house, we will also be subject to additional licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, fire hazard control, and disposal of hazardous or potential hazardous substances. Some of the most important requirements applicable or potentially applicable to us include:

Additionally, due to the nature of our products as radiation producing medical devices, we are also subject to certain state laws and regulations related to the sale of our products. Although we have taken steps intended to ensure our compliancefully comply with such state laws and regulations, our failure to fully comply with these requirements could result in fines or penalties and could also adversely affect our ability to sell our products.

Government regulation may impede our ability to the manufacture our existing and future products. Government regulation also could delay the marketing of new products for a considerable period of time and impose costly procedures on activities. The U.S. Food and Drug Administration and other regulatory agencies may not clear or approve any future products on a timely basis, if at all. Any delay in obtaining, or failure to obtain, these approvals could negatively impact the marketing of any future products and reduce our product revenues. Regulatory bodies may review products once they are on the market and determine that they do not satisfy applicable regulatory requirements. Failure to comply with requisite requirements may lead to European Economic Area regulatory bodies ordering the suspension or withdrawal of products from the European Economic Area market or, as discussed below, notified bodies withdrawing certificates of conformity for devices or the underlying quality systems.

Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our technologies, which could harm our business. We could also be subject to new international, federal, state or local regulations that could affect our research and development programs and harm our business in unforeseen ways.

Product deficiencies could result in field actions, recalls, substantial costs or write-downs; thesewhich could lead to the delay or termination of ongoing trials, if any, and harm our reputation, business or financial results.

Our products are subject to various regulatory guidelines and involve complex technologies. The U.S. Food and Drug Administration and similar foreign governmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture that could affect patient safety. Manufacturers may, under their own initiative, conduct a product notification or recall to inform physicians of changes to instructions for use or if a deficiency in a device is found or suspected.

Identified quality problems, such as failure of critical components, or the failure of third parties to supply us with sufficient conforming quantities of these products or components, could impact the availability of our products in the marketplace or lead to adverse clinical events. In addition, product improvements or product redundancies could result in scrapping or expensive rework of products, and our business, financial condition or results of operations could suffer as a result. Product complaints, quality issues and necessary corrective and preventative actions could result in communications to customers or patients, field actions, require the scrapping, rework, recall or replacement of products, result in substantial costs or write-offs, or harm our business reputation and financial results. Further, these events could adversely affect our relationships with our customers or affect our reputation, which could materially adversely affect our earnings, results and financial viability.

A future field action or recall announcement could harm our reputation with customers, negatively affect our sales, and subject us to U.S. Food and Drug Administration (or similar governmental authority) enforcement actions. Moreover, depending on the corrective action we take to redress a product’s deficiencies or defects, the U.S. Food and Drug Administration (or similar governmental authority) may require, or we may decide, that we will need to obtain new approvals or clearances for the product before we market or distribute the corrected product. Seeking these approvals or clearances may delay our ability to replace the recalled products in a timely manner. If we do not adequately address problems associated with our products, we may face additional regulatory enforcement action, including U.S. Food and Drug Administration (or similar governmental authority) warning letters, product seizures, injunctions, administrative penalties, or civil or criminal fines.

Any identified quality issue can both harm our business reputation and result in substantial costs and write-offs, which in either case could materially harm our business and financial results.

The off-label use or misuse of our products may harm our imagereputation in the marketplace, result in injuries that lead to costly product liability suits, or result in costly investigations and regulatory agency sanctions under certain circumstances.

The products we currently market in the U.S. have been cleared by the U.S. Food and Drug Administration for specific indications. Our clinical support staff and marketing and sales force have been trained not to promote our products for uses outside of the cleared indications for use, known as “off-label uses.” However, if a physician uses our products outside the scope of the cleared indications, there may be increased risk of injury to patients. Furthermore, the use of our products for indications other than those cleared by the U.S. Food and Drug Administration may not effectively treat the conditions associated with the off-label use, which could harm our reputation in the marketplace among physicians and patients, adversely affecting our operations.

If the U.S. Food and Drug Administration determines that our promotional materials or training constitute promotion of an off-label or other improper use, it could request that we modify our training or promotional materials, or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, a warning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our business activities to constitute promotion of an off-label use, which could result in significant penalties, including, but not limited to, criminal, civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs, and the curtailment of our operations. Any of these events could significantly harm our business and results of operations.

The advertising and promotion of our products is subject to European Economic Area Member States governing the advertising and promotion of medical devices. In addition, voluntary European Union and national Codes of Conduct provide guidelines on the advertising and promotion of our products to the general public and may impose limitations on promotional activities with healthcare professionals. These regulations or codes may limit our ability to affectively market our products, or we could run afoul of the requirements imposed by these regulations, causing reputational harm, imposing potentially substantial costs, and adversely affecting our operations as a result.

We are required to comply with medical device reporting requirements and must report certain malfunctions, deaths, and serious injuries associated with our products, which can result in voluntary corrective actions or agency enforcement actions.

Under the U.S. Food and Drug Administration medical device reporting regulations (21 CFR 803), medical device manufacturers are required to submit information to the U.S. Food and Drug Administration when they receive a report or become aware that a device has or may have caused or contributed to a death or serious injury or has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medical devices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell (MEDDEV 2.12-1) to the Competent Authority in whose jurisdiction the incident occurred through the European Vigilance process.

If an event subject to medical device reporting requirements occurs, we will need to comply with the reporting requirements, which would adversely affect our reputation and subject us to actions by regulatory authorities, such as ordering recalls, imposing fines, or seizing the affected products. Furthermore, any corrective action, whether voluntary or involuntary, will require the dedication of time and capital and will distract management from operating our business. Any of the foregoing would further harm our reputation and financial results.

Healthcare policy changesmaychanges may have a material adverse effect on our business.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, included, among other things, a deductible 2.3% excise tax on any entity that manufactures or imports medical devices offered for sale in the U.S., with limited exceptions, effective January 1, 2013. This excise tax imposesimposed a significant increase in the tax burden on the medical device industry, and if our efforts to offset theindustry. This excise tax are unsuccessful, the increased tax burden could have an adverse effect on our results of operations and cash flows. However, this excise tax has recently been suspended for 2016 and 2017. The tax remains uncertain for future years.was repealed in 2018. Other elements of this Act,law, including comparative effectiveness research, an independent payment advisory board, payment system reforms including shared savings pilots and other provisions, may significantly affect the payment for, and the availability of, healthcare services and may result in fundamental changes to federal healthcare reimbursement programs, any of which may materially affect numerous aspects of our business.

Other healthcare reform measures may result in more rigorous coverage criteria and in additional downward pressure on the reimbursement received for procedures utilizing our products. In addition, other legislative changes have been proposed and adopted since the Actlaw discussed above was enacted that may adversely affect our revenues. These changes include aggregate reductionsChanges to Medicare payments to providers of up to 2% per year effective April 2013 which, due to subsequent legislative amendments to the statute, will stay in effect through 2024 unless additional Congressional action is taken. Additionally, in 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, reduced Medicare payments to several providers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These newexisting laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on our business and financial operations. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to increase revenue, attain profitability, or commercialize our devices. In addition, other legislative changes may be enacted or existing regulations, guidance or interpretations may be changed, each of which may adversely affect our operations.

In addition, the requirements or restrictions imposed on us or our products may change, either as a result of administratively adopted policies or regulations or as a result of the enactment of new laws. Moreover, there have been recent public announcements by members of the U.S. Congress, President Trump and his administration regarding their plans to repeal and replace the Affordable Care Act, Medicare, and Medicaid. Although we cannot predict the ultimate content or timing of any healthcare reform legislation, potential changes resulting from any amendment, repeal or replacement of these programs, including any reduction in the future availability of healthcare insurance benefits, could adversely affect our business and future results of operations.

Risks Related to our Intellectual Property

If our patents and other intellectual property rights do not adequately protect our products, we may lose market share to competitors and be unable to operate our business profitably.

Our success significantly depends significantly on our ability to protect our proprietary rights to the technologies used in our products. We rely on the patent protection of two U.S. patents and two foreign patents which we have acquired, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure, confidentiality and other contractual restrictions to protect our proprietary technology. We also have patent applications currently pending and in the process of being submitted. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitive advantage. For example, some or all of our pending patent applications or any future pending applications may be unsuccessful. The U.S. Patent and Trademark Office may deny or require significant narrowing of claims in our pending patent applications or future patent applications, and patents issued as a result of these patent applications, if any, may not provide us with significant commercial protection or be issued in a form that is advantageous to us. We could also incur substantial costs in proceedings before the U.S. Patent and Trademark Office. These proceedings could result in adverse decisions as to the priority of our inventions and the narrowing or invalidation of claims in our issued patents. Third parties may successfully challenge our issued patents and those that may be issued in the future, which would render these patents invalidated or unenforceable, and which could limit our ability to stop competitors from marketing and selling related products. In addition, our pending patent applications include claims to aspects of our products and procedures that are not currently protected by issued patents, and third parties may successfully patent those aspects before us or otherwise challenge our rights to these aspects.

Both the patent application process and the process of managing patent disputes can be time consuming and expensive. Competitors may be able to design around our patents or develop products that provide outcomes that are comparable to our products. Although we have entered into confidentiality agreements and intellectual property assignment agreements with certain of our employees, consultants and advisors in order to protect our intellectual property and other proprietary technology, these agreements may not be enforceable or may not provide meaningful protection for trade secrets or other proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements. In addition, we have not sought patent protection in all countries where we sell our products. If we fail to timely file a patent application in any such country or major market, we may be precluded from doing so at a later date. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories in which we have patent protection that may not be sufficient to terminate infringing activities. Furthermore, the laws of some foreign countries may not protect intellectual property rights to the same extent as the laws of the U.S., if at all.

In the event a competitor infringes upon one of our patents or other intellectual property rights, enforcing those patents and rights may be difficult and time consuming. Even if successful, litigation to defend our patents against challenges or to enforce our intellectual property rights could be expensive and time consuming and could divert management’s attention from managing our business. Moreover, we may not have sufficient resources to defend our patents against challenges or to enforce our intellectual property rights, any of which would adversely affect our ability to compete and our business operations as a result.

If our trademarks or trade names are not adequately protected, then we may be unable to build name recognition in our markets of interest and our business may be adversely affected.

Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to infringe other marks. We may be unable to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in markets of interest. If our trademarks are challenged, infringed upon, circumvented, or declared generic or infringing, or if we are unable to establish name recognition based on our trademarks and trade names, then we may be unable to compete effectively and our business may be adversely affected.

The medical device industry is characterized by extensive patent litigation, and if we become subject to litigation, it could be costly, result in the diversion of management’s attention, require us to pay significant damages or royalty payments, or prevent us from marketing and selling our existing or future products.

The medical device industry is characterized by extensive litigation and administrative proceedings over patent and other intellectual property rights. Determining whether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. Our competitors may assert that their products, the components of those products, the methods of using those products, or the methods we employ in processing those products are covered by U.S. or foreign patents held by them. In addition, they may claim that their patents have priority over us because their patents were issued first. Because patent applications can take many years to issue, our products that currently do not infringe on existing issued patents may later infringe on patents that are pending now or in the future. Our products might also inadvertently infringe on currently issued patents. As the number of participants in the market for skin cancer and general oncology devices and treatments increases, the possibility of patent infringement claims against us increases. Any infringement claims, litigation or other proceedings would place a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation.

A larger more established company could allege that we infringed its patent, and that we owe royalty payments on sales of certain products as a result. Any claim against us, even without merit, may cause us to incur substantial costs, and could place a significant strain on our financial resources, divert the attention of management from the core business and harm our reputation. If the appropriate authority upholds the company’s patent as valid and enforceable and finds that we infringed on the patent, we could be required to pay substantial damages, including treble, or triple, damages and royalties if an infringement is found to be willful, and we could be prevented from selling our products unless we obtain a license or are able to redesign our products to avoid infringement. A license may not be available on reasonable terms, if at all, and we may be unable to redesign products in a way that would not infringe those patents. If we fail to obtain any required licenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable to commercialize one or more of our products, either of which could have a significant adverse effect on our business, financial condition and results of operations.

Any potential intellectual property litigation also could force us to do one or more of the following:

Any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.

We may indemnify our customers and international distributors with respect to infringement by our products of the proprietary rights of third parties. Third parties may assert infringement claims against customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf of customers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of customers or distributors or may be required to obtain licenses for the products they use, each which would adversely affect our operations. If we cannot obtain all necessary licenses on commercially reasonable terms, customers may be forced to stop using our products, which would materially and adversely affect our business.

We may be subject to damages resulting from claims that we, our employees or independent distributors have wrongfully used or disclosed alleged trade secrets of competitors or are in breach of non-competition or non-solicitation agreements with our competitors.

Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors. Many of our independent distributors sell, or in the past have sold, products of competitors. We may be subject to claims that we, our employees or independent distributors have inadvertently or otherwise used or disclosed the trade secrets or other proprietary information of our competitors. In addition, we have been and may in the future be subject to claims that we caused an employee or independent distributor to break the terms of his or her non-competition agreement or non-solicitation agreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management. If we fail in defending these claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products, which could have an adverse effect on our business, financial condition and results of operations.

Adverse outcomes in litigation or similar proceedings could adversely impact our business.

We currently are, and may in the future be, named as a party to litigation or other similar legal proceedings. Adverse outcomes in any or all of these proceedings could result in monetary damages or injunctive relief that could adversely affect our ability to continue conducting our business. While our management does not believe any of the proceedings currently pending against us are material to our business such matters are subject to inherent uncertainties and management’s view of these matters may change in the future. If an unfavorable final outcome in any such matter becomes probable and reasonably estimable, our financial condition could be materially and adversely affected.

Risks Related to the Ownership of our Securities

Limited trading activity for shares of our common stock and warrants may contribute to price volatility.

While our common stock and warrants are listed and traded on the Nasdaq Capital Market, there has been limited trading activity in our securities. The average daily trading volume of our common stock since the shares began trading on July 26, 2016 through December 31, 2016 was approximately 2,000 shares. Due to the limited trading activity of our securities, relativity small trades may have a significant impact on the price of our securities.

With two exceptions, we have never declared or paid cash dividends on our common stock and do not anticipate paying dividends in the foreseeable future. As a result, you must rely on price appreciation of our common stock for a return on your investment in the foreseeable future. 

Except for a required tax distribution in 2014, in the aggregate amount of $45,421, and a one-time payment in the aggregate amount of approximately $2.6 million paid to former holders of our units with a preferred return in 2016, we have never declared or paid cash dividends on our common stock. We currently expect to retain our funds and future earnings to support the operation, growth and development of our business. We do not anticipate paying any cash dividends on our common stock in the foreseeable future. As a result, a return on your investment in the near future will occur only if our share price appreciates. Our securities prices may not appreciate in value or maintain the prices at which you purchased our securities, and in either case, you may not realize a return on investment or could lose all or part of your investment in our securities.

Furthermore, any future determination to declare cash dividends will be made at the discretion of our board of directors and will be subject to compliance with applicable laws and covenants under any future credit facilities, which may restrict or limit our ability to pay dividends. For example, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent of the lender, provided that we may pay dividends solely in common stock. Also, the form, frequency and amount of dividends will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. We may not pay dividends as a result of any of the foregoing, and in these cases, you will need to rely on price appreciation of our common stock for a return on your investment.

TheGeneral stock market volatility could result in significant declines in the trading price of our securities, may be volatile, and you could lose all or a substantial part of your investment. 

Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our securities. In addition, limited trading volume of our securities may contribute to its future volatility. Price declines in our securities could result from general market and economic conditions, some of which are beyond our control, and a variety of other factors, including any of the risk factors described in this Annual Report on Form 10-K. These broad market and industry factors may harm the market price of our securities, regardless of our operating performance, and could cause you to lose all or part of your investment in our securities since you might be unable to sell your securities at or above the price you paid. Factors that could cause fluctuations in the market price of our securities include the following:

In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

We are both an “emerging growth company” and a “smaller reporting company”company,” and the reduced reporting requirements applicable to emerging growth companies and smaller reporting companies may make our common stock less attractive to investors. 

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies but not to “emerging growth companies,” including, but not limited to:

We will remain an emerging growth company until the earlier of (1) December 31, 2021, (2) the last day of the year in which (a) we have total annual gross revenue of at least $1 billion, or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30^th, and (3) the date on which we have issued more than $1 billion in non-convertible debt during the prior three-year period. Investors may find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as a result of any choices to reduce future disclosure, there may be a less active trading market for our common stock and the price of our common stock may be more volatile.

Under the Jumpstart Our Business Startups Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

We are a “smaller reporting company,” meaning that our outstanding common stock held by nonaffiliates had a value of less than$75than$250 million at the end of our most recently completed second fiscal quarter. Thus, even if we are no longer an emerging growth company, as a smaller reporting company, we could take advantage of certain reduced governance and disclosure requirements, including not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting. As aresult,aresult, investors and others may be less comfortable with the effectiveness of our internal controls and the risk that materialweaknessesmaterialweaknesses or other deficiencies in internal controls go undetected may increase. In addition, as a smaller reporting company, we takeadvantagetakeadvantage of our ability to provide certain other less comprehensive disclosures in our SEC filings, including, among other things, providing onlytwoonlytwo years of audited financial statements in annual reports and simplified executive compensation disclosures. Consequently, it may be morechallengingmorechallenging for investors to analyze our results of operations and financial prospects, as the information we provide to stockholders may bedifferentbedifferent from what one might receive from other public companies in which one hold 5holds shares.

Our executive officers, directors and principal stockholders may exert control over us and may exercise influence over matters subject to stockholder approval. 

Our executive officers and directors, together with their respective affiliates, beneficially owned approximately 41%30% of our outstanding common stock as of December 31, 2016.February 5, 2020. Accordingly, these stockholders, if they act together, may exercise substantial influence over matters requiring stockholder approval, including the election of directors and approval of corporate transactions, such as a merger. This concentration of ownership could have the effect of delaying or preventing a change in control or otherwise discourage a potential acquirer from attempting to obtain control over us, which in turn could have a material adverse effect on the market value of our common stock.

If securities or industry analysts do not publish research or publish unfavorable or inaccurate research about our business, the price of our securities and trading volume could decline. 

The trading market for our securities will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. We may be unable to attract or sustain coverage by well-regarded securities and industry analysts. If either none or only a limited number of securities or industry analysts cover us or our business, or if these securities or industry analysts are not widely respected within the general investment community, the trading price for our securities would be materially and negatively impacted. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who cover us or our business downgrade our securities or publish inaccurate or unfavorable research about us or our business, the price of our securities would likely decline. If one or more of these analysts cease coverage of us or our business, or fail to publish reports on us or our business regularly, demand for our securities could decrease, which might cause the price of our securities and trading volume to decline.

Our certificate of incorporation, our bylaws and Delaware law contain provisions that could discourage another company from acquiring us and may prevent attempts by our stockholders to replace or remove our current directors and management. 

Provisions of Delaware law (where we are incorporated), our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your stock. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or remove our board of directors. These provisions include:

In addition, we are subject to Section 203 of the Delaware General Corporation Law, which may have an anti-takeover effect with respect to transactions not approved in advance by our board of directors, including discouraging takeover attempts that could have resulted in a premium over the market price for shares of our common stock.

These provisions will apply even if a takeover offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that our board of directors determines is not in our and our stockholders’ best interests and could also affect the price that some investors are willing to pay for our common stock.

Our certificate of incorporation will provideprovides that the Court of Chancery of the State of Delaware will beis the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees. 

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage these lawsuits against us and our directors, officers and other employees. If a court were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the action in other jurisdictions, which could harm our business and financial condition.

If we fail to maintain proper and effective internal controls, our ability to produce accurate and timely financial statements could be impaired and investors’ views of us or our business could be harmed, resulting in a decrease in value of our common stock. 

As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in our internal controls. In addition, beginning with our annual report on Form 10-K for our year ending December 31, 2017 to be filed in 2018, we will beare required to furnish a report by management on the effectiveness of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act. We are in the process of designing, implementing and testing the internal control over financial reporting required to comply with this obligation, which process is time-consuming, costly and complicated. In addition, our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting beginning with our annual report on Form 10-K following the date on which we are no longer an emerging growth company, which may be up to five full years following the date of our IPO, or the date we are no longer qualify as a smaller reporting company. Our compliance with Section 404 of the Sarbanes-Oxley Act will require us to incur substantial accounting expense and expend significant management efforts. If we are unable to comply with the requirements of Section 404 in a timely manner, or we or our independent registered public accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our common stock could decline and we could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities, which would require additional financial and management resources.

Our ability to implement our business plan successfully and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. We expect that we will need to continue to improve existing, and implement new, operational and financial systems, procedures and controls to manage our business effectively. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, may cause our operations to suffer and we may be unable to conclude that our internal control over financial reporting is effective and to obtain an unqualified report on internal controls from our auditors when required under Section 404 of the Sarbanes-Oxley Act. Moreover, we may not implement and maintain adequate controls over our financial processes and reporting in the future. Even if we were to conclude, and, when required, our auditors were to concur, that our internal control over financial reporting provided reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, because of our inherent limitations, internal control over financial reporting may not prevent or detect fraud or misstatements or omissions.

Our operations may be impaired if our information technology systems fail to perform adequately or if we are the subject of a data breach or cyberattack.

Our information technology systems are critically important to operating our business efficiently. We rely on our information technology systems to manage our business data, communications, employee information, and other business processes. We outsource certain business process functions to third-party providers and similarly rely on these third parties to maintain and store confidential information on their systems. The failure of these information technology systems to perform as we anticipate could disrupt our business and could result in transaction errors, processing inefficiencies, and the loss of sales and customers, causing our business and results of operations to suffer.

Although we protect our information technology systems, we have experienced varying degrees of cyber-incidents in the normal conduct of our business, including viruses, worms, phishing and other malicious activities. Although there have been no serious consequences to date, such breaches could result in unauthorized access to information including customer, supplier, employee, or other company confidential data. We do carry insurance against these risks, perform penetration tests from time to time, and design our business processes to attempt to mitigate the risk of such breaches. However, our efforts to mitigate these risks may be unsuccessful for security breaches not to occur. Moreover, the development and maintenance of these measures requires continuous monitoring as technologies change and efforts to overcome security measures evolve. We have experienced, and expect to continue to experience, cyber security threats and incidents, none of which has been material to us to date. However, a successful breach or attack could have a material negative impact on our operations and subject us to consequences such as direct costs associated with incident response.

PART II.

Common Stock Market Prices

Our common stock trades on the Nasdaq Capital Market under the symbol “SRTS.” We had a total of 11141 stockholders of record as of February 28, 2017.March 2, 2020. The following table presents the range of high and low closing sales prices reported on the Nasdaq Capital Market.

Dividends

We have notnever declared or paid any dividend on our common stock. Following the completion of our initial public offering, we paid a cash dividend of approximately $2.6 million to former holders of our limited liability company units with a preferred return. We anticipate that for the foreseeable future all earnings will be retained for use in our business and no cashwe do not expect to pay dividends will be paid to stockholders. Any future payment of cash dividends in the future on the Company’sour common stock will be dependent upon our financial condition, results of operations, current and anticipated cash requirements, plans for expansion, as well as other factors that theour Board of Directors deems relevant. Additionally, certain contractual agreements and provisions of Delaware law impose restrictions on our ability to pay dividends. For example, our current revolving line of credit restricts our ability to pay dividends or make any distributions or payments or redeem, retire or purchase any capital stock without the prior written consent of the lender, provided that we may pay dividends solely in common stock.stock without prior consent. Additionally, Section 170(a) of the Delaware General Corporation Law (“DGCL”) only permits dividends to be declaredpaid out of two legally available sources: (1) out of surplus, or (2) if there is no surplus, out of net profits for the year in which the dividend is declared or the preceding year (so-called “nimble dividends”). However, dividends may not be declared out of net profits if “the capital of the corporation, computed in accordance with sections 154 and 244 of the DGCL, shall have been diminished by depreciation in the value of its property, or by losses, or otherwise, to an amount less than the aggregate amount of the capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets.” Contractual obligations and applicable law will restrict our ability to declare and pay dividends in the future.

Use of Proceeds from the Sale of Registered Securities

In June 2016, we completed an initial public offering, or IPO, of units consisting of one share of common stock and one warrant to purchase one share of common stock. In connection with the IPO, we issued 2,300,000 units of our common stock at a price of $5.50 per unit, including 300,000 units pursuant to the underwriters’ full exercise of their over-allotment option for an aggregate offering price of $12.65 million. The offer and sale of all of the securities in the IPO were registered under the Securities Act pursuant to a registration statement on Form S-1, as amended (File No. 333-209451), which was declared effective by the SEC on June 2, 2016.

We received total net proceeds from the IPO of approximately $10.5 million after deducting underwriting discounts and commissions of approximately $0.9 million and other offering expenses of approximately $1.4 million. We used approximately $2.6M for the payment of dividends to former preferred investors and approximately $0.5M in operating activities.

The remaining proceeds from the IPO have been invested in highly-liquid money market funds and debt securities with maturities of 18 months or less. There has been no material change in the planned use of proceeds from our IPO as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act on June 2, 2016.

Unregistered Sales of Securities

There were no unregistered sales of securities during the year ended December 31, 2016.2019.

Purchases of Equity Securities by the Registrant and Affiliated Purchasers

We did not repurchase any shares of our common stock during the year ended December 31, 2016.None.

Throughout this section, Sensus Healthcare, Inc. is referred to as “Company,” “we,” “us,” or “our.”

CAUTION CONCERNING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K, including this MD&A section, contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, among others, statements about our beliefs, plans, objectives, goals, expectations, estimates and intentions that are subject to significant risks and uncertainties and are subject to change based on various factors, many of which are beyond our control. The words “may,” “could,” “should,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “intend,” “plan,” “target,” “goal,” and similar expressions are intended to identify forward-looking statements.

All forward-looking statements, by their nature, are subject to risks and uncertainties. Our actual future results may differ materially from those set forth in our forward-looking statements. Please see the Introductory Note andItem 1A Risk Factors of this Annual Report for a discussion of factors that could cause our actual results to differ materially from those in the forward-looking statements.

However, other factors besides those listed inItem 1A Risk Factors or discussed in this Annual Report also could adversely affect our results, and you should not consider any such list of factors to be a complete set of all potential risks or uncertainties. Any forward-looking statements made by us or on our behalf speak only as of the date they are made. We do not undertake to update any forward-looking statement, except as required by applicable law.

Overview

As discussed elsewhere in this Report, we seek to achieve consistent profitability. However, we face a number of uncertainties in 2020 that could impact our ability to achieve this goal. These include ongoing international trade issues and the coronavirus epidemic. Either of these matters could adversely affect our ability to do business in a number of countries and geographic regions, including China.

In order to achieve profitability, we are continuing to reduce expenses, although we are maintaining and, in some cases, increasing certain expenses that we deem important to our future growth and profitability. For example, we intend to maintain an appropriate level of research and development expenses.

Components of our results of operations

We manage our business globally within one reportable segment, which is consistent with how our management reviews our business, prioritizes investment and resource allocation decisions and assesses operating performance.

Additional disclosures have been included within Note 1 – Organization and customer acceptance becomes certain.Summary of Significant Accounting Policies of the consolidated financial statements.

Deferred revenue consists of payments from customers for separately priced service contracts, sales pending regulatory approval and deposits on products.

We provide warranties, generally one year, in conjunction with the sale of our product. These warranties are short term in nature and entitle the customer to repair, replacement, or modification of a defective product subject to the terms of the respective warranty. We record an estimate of future warranty claims at the time we recognize revenue from the sale of the product based upon management’s estimate of the future claims rate.

Shipping and handling costs are expensed as incurred and are included in cost of sales.

Cost of sales

Since 2010, we have used a third party manufacturer for the production and manufacture of our main products, the SRT-100 product line, in accordance with our product specifications. Cost of sales consists primarily of direct material, direct labor, overhead, depreciation and amortization. A significant portion of our cost of sales consists of costs paid to our third party manufacturer.

Gross profit

Gross profit

We calculate gross profit as net revenue less cost of sales. Our gross profit has been and will continue to be affected by a variety of factors, including average selling price, manufacturing costs, production volumes, product reliability and the implementation over time of cost-reduction strategies. Our gross profit may fluctuate from quarter to quarter.

Selling and marketing

We focus on two primary markets - private dermatology practices and radiation oncologists in both private and hospital settings. We currently employ a multi-tier sales strategy in an attempt to optimize geographic coverage and focus on what we perceive to be our key markets. This multi-tier sales model uses a direct salesforce in the U.S. and international dealers and distributors. We expect the amount of our sales

General and marketing expense to increase as we continue to expand our sales force and marketing activities.administrative

General and administrative

General and administrative expense or G&A, consists primarily of salaries, employee benefits, bonuses, and related costs for personnel who support our general operations such as executive management, finance, accounting and administrative functions, as well as legal and other professional fees, director and officer insurance and other public company expenses.

Research and development

Research and development costs relate to products under development by us and quality and regulatory costs and are expensed as incurred. We expect the amount of our research and development, or R&D, expense to increase as we continue to innovate and introduce new products and technologies.

Other income (expense)

Other income (expense) primarily consists of interest earned on cash balances and investments less interest payments made pursuant to our secured credit facility with Silicon Valley Bank. Our interest expense will fluctuate in future periods to the extent we incur additional, or pay down, indebtedness.

Income taxes

Until December 31, 2015, the Company waswe were organized as a limited liability corporation (LLC) that had elected to be taxed as a pass-through entity and accordingly, we did not recognize a federal or state income tax provision. Beginning in 2016, as a result of theour conversion from an LLC to a Delaware corporation, we began recording a provision for income tax (benefit) expense, which consists of income taxes in jurisdictions in which we conduct business. We are taxed at the rates applicable within each jurisdiction in which we operate or generate revenue. The composite income tax rate, tax provisions, deferred tax assets and deferred tax liabilities will vary according to the jurisdiction in which profits arise. Tax laws are complex and subject to different interpretations by management and the respective governmental taxing authorities, and require us to exercise judgment in determining our income tax provision, our deferred tax assets and liabilities and the valuation allowance recorded against our net deferred tax assets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation allowance is established when it is more likely than not that the future realization of all or some of the deferred tax assets will not be achieved.

On December 22, 2017, the United States enacted new federal tax reform legislation, resulting in significant changes from the prior tax law. The new tax law reduced the federal corporate income tax rate to 21% from 35%, effective January 1, 2018. Our federal income tax expense for periods beginning in 2018 was based on the new rate. The new tax law also permits immediate deduction of 100% of the costs of qualified property that have been incurred and the property placed in service during the period from September 27, 2017 to December 31, 2022. This provision will begin to phase out by 20% per year beginning January 1, 2023 and will be completely phased out as of January 1, 2027.

Our subsidiary in Israel is taxed on its taxable income. The current corporate tax rate in Israel is 23%.

Inflation

Inflation has not had a material impact on net sales, revenues or income from continuing operations for our two most recent years as a result of historically low levels of inflation.

Significant trends and uncertainties impacting our business

Many third party payors follow coverage decisions and payment amounts determined by the Centers for Medicare and Medicaid Services, or CMS, which administers the U.S. Medicare program, in setting their coverage and reimbursement policies. Effective January 1, 2015 and 2016, the total reimbursement for an episode of care remained similar to the reimbursement in prior years.

Liquidity and Capital Resources

Overview

Overview

In general terms, liquidity is a measurement of our ability to meet our cash needs. For the years ended December 31, 2019 and 2018, a significant source of funding has been from cash flows from financing activities, including the exercise of investor warrants during 2019 and our public offering in 2018. We believe that proceeds from exercises of warrants, our public offerings, our borrowing capacity and our access to capital resources are sufficient to meet our anticipated operating capital and funding requirements for the next 12 months from the issuance date of this annual report. Our liquidity position and capital requirements may be impacted by a number of factors, including the following:

Our primary short-term capital needs, which are subject to change, include expenditures related to:

We regularly evaluate our cash requirements for current operations, commitments, capital requirements and business development transactions, and we may elect to raise additional funds for these purposes in the future. As of December 31, 2016, we had approximately $11.5 million in cash, cash equivalents and short-term corporate bonds as well as a $3.0 million line of credit which serve as a source of liquidity for our cash needs.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with generally accepted accounting principles in the U.S., or GAAP. We have identified certain accounting policies as critical to understanding our financial condition and results of our operations. For a detailed discussion on the application of these and other accounting policies, see the notes to our financial statements included in this Annual Report on Form 10-K.

JOBS Act

We qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act. For as long as we are an “emerging growth company,” we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, reduced disclosure obligations relating to the presentation of financial statements in Management’s Discussion and Analysis of Financial Condition and Results of Operations, exemptions from the requirements of holding advisory “say-on-pay” votes on executive compensation and stockholder advisory votes on golden parachute compensation. We have availed ourselves of the reduced reporting obligations and executive compensation disclosure in this Annual Report on Form 10-K, and expect to continue to avail ourselves of the reduced reporting obligations available to emerging growth companies in future filings.

In addition, an emerging growth company can delay its adoption of certain accounting standards until those standards would otherwise apply to private companies. However, we have chosen to “opt out” of such extended transition period, and as a result, we plan to comply with any new or revised accounting standards on the relevant dates on which non-emerging growth companies must adopt such standards. Section 107 of the JOBS Act provides that our decision to opt out of the extended transition period for complying with new or revised accounting standards is irrevocable.
