PART I

Overview

TransEnterix is a medical device company that is digitizing the interface between the surgeon and the patient to improve minimally invasive surgery by addressing the clinical and economic challenges associated with current laparoscopic and robotic options in today's value-based healthcare environment. The Company is focused on the commercialization of the Senhance™ Surgical System, which digitizes laparoscopic minimally invasive surgery. The system allows for robotic precision, haptic feedback, surgeon camera control via eye sensing and improved ergonomics while offering responsible economics.

The Senhance System has been granted a CE Mark in Europe for laparoscopic abdominal and pelvic surgery, as well as limited thoracic operations excluding cardiac and vascular surgery. In April 2017, the Company submitted a 510(k) application to the FDA for the Senhance System. On October 13, 2017, the Company received 510(k) clearance from the FDA for use in laparoscopic colorectal and gynecologic surgery.  These indications cover 23 procedures, including benign and oncologic procedures.  We anticipate expanding the indications for use in the middle of 2018. The Senhance System is available for sale in the U.S., the EU and select other countries.

The Senhance System is a multi-port robotic surgery system which allows multiple robotic arms to control instruments and a camera. The system features advanced technology to enable surgeons with haptic feedback and the ability to move the camera via eye movement. The system replicates laparoscopic motion that is familiar to experienced surgeons, and integrates three-dimensional high definition, or 3DHD, vision technology. The Senhance System also offers responsible economics to hospitals by offering robotic technology with reusable instruments thereby reducing additional costs per surgery when compared to other robotic solutions.

The Company has also developed the SurgiBot™ System, a single-port, robotically enhanced laparoscopic surgical platform. On December 18, 2017, the Company announced that it had entered into an agreement with Great Belief International Limited, or GBIL, to advance the SurgiBot System towards global commercialization.  The agreement transfers ownership of the SurgiBot System assets, while the Company retains the option to distribute or co-distribute the SurgiBot System outside of China. Upon completion of the transfer of all SurgiBot System assets, GBIL will have the SurgiBot System manufactured in China and obtain Chinese regulatory clearance from the China Food and Drug Administration, or CFDA, while entering into a nationwide distribution agreement with China National Scientific and Instruments and Materials Company, or CSIMC, for the Chinese market.  The agreement provides the Company with proceeds of at least $29 million, of which $7.5 million was received in December 2017. An additional $7.5 million is expected to be received by March 31, 2018, which includes a $3.0 million equity investment at $2.33 per share. The remaining $14 million, representing minimum royalties, will be paid beginning at the earlier of receipt of Chinese regulatory approval or five years.

We believe that future outcomes of minimally invasive surgery will be enhanced through our combination of more advanced tools and robotic functionality, which are designed to: (i) empower surgeons with improved precision, dexterity and visualization; (ii) improve patient satisfaction and enable a desirable post-operative recovery; and (iii) provide a cost-effective robotic system, compared to existing alternatives today, for a wide range of clinical applications. Our strategy is to focus on the development and commercialization of the Senhance System.

The Company operates in one business segment. Please see the disclosure in Note 2 “Summary of Significant Accounting Policies – Segments” in the Notes to our Consolidated Financial Statements in Item 8 of this Annual Report regarding our business operations in the U.S. and elsewhere.

Market Overview

Over the past two decades, laparoscopic surgery has emerged as a minimally invasive alternative to open surgery. In laparoscopic surgery, multiple incisions are necessary to provide surgical access ports. Carbon dioxide gas insufflation is then used to create room in the body cavity, and long rigid instruments are introduced through ports placed in the incisions to perform surgical tasks. Millions of laparoscopic surgical procedures across a broad range of clinical applications are now performed each year worldwide, though many surgeries are still performed in an open fashion.

While laparoscopy has improved the invasive nature of many previously open procedures, it still has many limitations. Traditional, or rigid, laparoscopy still requires multiple incisions to achieve the visualization and instrument triangulation required to perform successful surgery. Rigid laparoscopy also creates physical challenges by forcing the surgeon’s hands and arms into awkward angles, requiring the surgeon to hold instruments in fixed positions for long periods of time, and requiring an assistant to stabilize and move a laparoscopic camera. Another challenge associated with rigid laparoscopic surgery is the creation of a cumbersome and potentially tissue-damaging fulcrum at the patient’s abdominal wall where instruments are manipulated. Nearly all laparoscopic instruments are rigid instruments that lack internal articulation to enhance dexterity in complex tasks. Most laparoscopic surgeries are performed with two-dimensional (2-D) visualization of the operative field, making depth perception difficult.

1

Despite such limitations, traditional laparoscopy remains the prevalent technique in minimally invasive surgery. We believe that robotic devices that replicate laparoscopic motion are more comfortable for surgeons to adopt, thereby increasing the opportunity to enhance traditional surgical methods with robotics. Our Senhance System mimics laparoscopic surgery.

Robotic and computer controlled assistance have developed as technologies that offer the potential to improve upon many aspects of the laparoscopic surgical experience. Hundreds of thousands of robotic-assisted surgical procedures are now performed each year worldwide, but they still represent a small fraction of the total laparoscopic procedures performed. While initial widespread adoption of robotic-assisted surgery was focused on urologic and gynecologic procedures that were primarily performed in an open fashion prior to robotics, recently developed robotic approaches have been applied to many other clinical applications, particularly in general surgery. Despite recent advances, we believe there remain many limitations associated with current robotic-assisted surgery systems used in connection with laparoscopic surgeries.

Product Overview

We are addressing the challenges in laparoscopy and robotic-assisted surgery with innovative products and product candidates that leverage the best features of both approaches to minimally invasive surgery.

Senhance System

On September 18, 2015, the Company entered into a Membership Interest Purchase Agreement, or the Purchase Agreement, with Sofar S.p.A., or Sofar, as seller, Vulcanos S.r.l., as the acquired company, and TransEnterix International, Inc., a direct, wholly owned subsidiary of the Company which was incorporated in September 2015, as buyer. The closing of the transactions occurred on September 21, 2015  pursuant to which the Company acquired all of the membership interests of Vulcanos from Sofar (now known as the Senhance Acquisition), and changed the name of Vulcanos to TransEnterix Italia S.r.l. For a description of the Senhance Acquisition and related transactions, see the disclosure titled “Senhance Acquisition and Related Transactions” under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Annual Report.

The Senhance System is a multi-port robotic surgery system which allows up to four arms to control robotic instruments and a camera. The system builds on the success of laparoscopy by enhancing the traditional features that surgeons have come to expect from existing products and by addressing some of the limitations associated with robotic surgery systems for laparoscopic procedures. The Senhance System also offers responsible economics to hospitals by offering robotic technology with reusable instruments with minimal additional costs per surgery when compared to laparoscopy. The Senhance System has been granted a CE Mark in Europe for laparoscopic abdominal and pelvic surgery, as well as limited thoracic operations excluding cardiac and vascular surgery. In April 2017, the Company submitted a 510(k) application to the FDA for the Senhance System. On October 13, 2017, the Company received 510(k) clearance from the FDA for use in laparoscopic colorectal and gynecologic surgery.  The Senhance System is available for sale in the U.S., the EU and select other countries.

Key features of the Senhance System are:

The Senhance System is manufactured for us by third party contract manufacturers. We or our manufacturers acquire raw materials and components of the Senhance System from vendors, some of which are sole suppliers. We believe our relationships with our vendors and manufacturing contractors are good. We further believe that we have the manufacturing and inventory reserves to meet our anticipated Senhance System sales for the foreseeable future. We are currently taking steps to develop redundant manufacturing and supply alternatives.

2

SurgiBot System

The SurgiBot System is designed to utilize flexible instruments through articulating channels controlled directly by the surgeon, with robotic assistance, while the surgeon remains patient-side within the sterile field. In June 2015, the Company submitted a 510(k) application to the FDA for the SurgiBot System. On April 19, 2016, the FDA notified the Company that the SurgiBot System did not meet the criteria for substantial equivalence based on the data and information submitted by TransEnterix in the 510(k) submission. Following the FDA determination, in May 2016, the Company implemented a restructuring plan.  The restructuring plan:  (1) reduced the Company’s workforce; (2) abandoned certain equipment related to the SurgiBot System; (3) cancelled contracts related to the SurgiBot System; (4) wrote down inventory related to the SurgiBot System; and (5) wrote off certain patents.  After interactions with the FDA, the Company determined that a new 510(k) application would need to be submitted in order to obtain clearance for the SurgiBot System.

Please see “Business - Overview” in this Item 1 of this Annual Report for a description of the 2017 agreement regarding the sale of the SurgiBot System assets.  

Products in Development

We are working to expand our portfolio of surgical instruments, accessories and other products to compliment the Senhance System.  We are currently focused on the development and regulatory clearance for advanced energy instruments, articulating instruments and 3 mm instruments for the Senhance System.  

Revenues

In the year ended December 31, 2017, we had six customers in Europe, one customer in the U.S., and one customer in Asia, who accounted for 61%, 18%, and 21% of our revenue. In the year ended December 31, 2016, we had one European customer, Humanitas Hospital in Milan, Italy, who accounted for 100% of our revenue. In the year ended December 31, 2015, the Company had no revenue. The Company is not dependent on current customers. Please see the disclosure in Note 2 “Summary of Significant Accounting Policies – Segments” in the Notes to our Consolidated Financial Statements in Item 8 of this Annual Report regarding the geographic locations of our revenues and assets in the U.S. and elsewhere.

Business Strategy

Our current strategy is to focus our resources on the commercialization of the Senhance System.

We believe that:

Sales and Marketing

We have recruited a sales and marketing team and have initiated commercialization of the Senhance System in the United States, Europe, the Middle East, Africa and limited countries in Asia.  We utilize distributors in a number of jurisdictions where we do not sell directly. Our distribution agreements typically provide exclusivity in a specific territory or jurisdiction.

We have initiated a Clinical Leadership Program with leading surgical centers in Europe and the United States to utilize the Senhance System. We believe the program helps improve our visibility and provides more widespread opportunity for observation of robotic surgery with the Senhance System. In addition, in December 2016 we opened a European training and research and development center in Milan, Italy, and in November 2017 we opened a training and research and development center at the Institute for Surgical Advancement at Florida Hospital Orlando.

Research and Development

During the fiscal years ended December 31, 2017, 2016 and 2015, we incurred research and development expenses of approximately       $22.0 million, $29.3 million and $29.7 million, respectively. In 2017, such expenses primarily related to the Senhance System development, including the preparation and submission of regulatory filings with the FDA.  In 2016, such expenses primarily related to the SurgiBot System development and the Senhance System development, including the preparation and submission of regulatory filings. In 2015, such expenses primarily related to the SurgiBot System development, including the preparation and submission of regulatory filings. We fund our research and development expenses primarily from proceeds raised from equity and debt financing transactions. We expect to continue to use equity and debt financing transactions to fund our research and development activities. No customers are obligated to pay any material portion of such research and development expenses.

Intellectual Property

We believe that our intellectual property and expertise is an important competitive resource. Our experienced research and development team has created a substantial portfolio of intellectual property, including patents, patent applications, trade secrets and proprietary know-how. We maintain an active program of intellectual property protection, both to assure that the proprietary technology developed by us is appropriately protected and, where necessary, to assure that there is no infringement of our proprietary technology by competitive technologies.

The following summarizes our current patent and patent application portfolio.

The Company’s patent portfolio includes 24 United States patents and 68 patents issued outside the United States, and more than 90 patent applications filed in the United States and abroad. We own all right, title and interest in approximately 140 of our patents and patent applications, and the rest are exclusively licensed to us.  We have granted a security interest to our intellectual property, including patents and patent applications to the Lender under our existing loan agreement.  See “Item 7 – Management’s Discussion and Analysis and Results of Operations – Debt Refinancing” for a description of our existing loan agreement.  

Several of our issued patents resulted from filings related to the Senhance System.  These include 5 United States patents, and 33 patents outside the United States. The earliest to expire US patents within this part of our portfolio will remain in force until 2030, and the earliest to expire non-US patents will expire in 2027.  The patent applications include over 75 that relate to the Senhance System or other aspects of robotic-assisted surgery. We intend to continue to seek further patent and other intellectual property protection in the United States and internationally, where available and when appropriate, as we continue our product development efforts.

Some of our issued patents and pending applications for the Senhance System, as well as associated technology and know-how, are exclusively licensed to TransEnterix Italia from the European Union. The license agreement with the European Union has a term which runs until the final licensed patent expires, unless the agreement is terminated earlier by mutual consent of the parties or for breach. The Company is currently in compliance with the terms of this license agreement.

Competition

Our industry is highly competitive, subject to change and significantly affected by new product introductions and other activities of industry participants. Many of our competitors have significantly greater financial and human resources than we do and have established reputations with our target customers, as well as worldwide distribution channels that are more established and developed than ours.

There are many competitive offerings in the field of minimally invasive surgery. Several companies have launched devices that enable reduced incision or single incision laparoscopic surgery with or without robotic assistance. Our surgical competitors include, but are not limited to: Johnson & Johnson, Medtronic plc, Applied Medical and Intuitive Surgical.

In addition to surgical device manufacturer competitors, there are many products and therapies that are designed to reduce the need for or attractiveness of surgical intervention. These products and therapies may impact the overall volume of surgical procedures and negatively impact our business.

Our ability to compete may be affected by the failure to fully educate physicians in the use of our products and products in development, or by the level of physician expertise. This may have the effect of making our products less attractive. Among currently available surgical robotic systems, we expect the Senhance System to differentiate on the basis of overall attractiveness to laparoscopic surgeons due to its ability to provide robotic benefits while leveraging their laparoscopic training and experience lower per procedure costs when compared to other robotic systems on the market today; and we expect the Senhance System to differentiate, in most cases, its ability to provide the surgeon with tactile feedback. Several medical device companies are actively engaged in research and development of robotic systems or other medical devices and tools used in minimally invasive surgery procedures. We cannot predict the basis upon which we will compete with new products marketed by others.

Government Regulation of our Product Development Activities

The U.S. government and foreign governments regulate the medical device industry through various agencies, including but not limited to, the U.S. FDA, which administers the Federal Food, Drug and Cosmetic Act, or the FDCA. The design, testing, manufacturing, storage, labeling, distribution, advertising, and marketing of medical devices are subject to extensive regulation by federal, state and local governmental authorities in the United States, including the FDA, and by similar agencies in other countries, including the European Union. Any device product that we develop must receive all requisite regulatory approvals or clearances, as the case may be, before it may be marketed in a particular country.

Device Development, Marketing Clearance and Approval

Medical devices are subject to varying levels of pre-market regulatory requirements. The FDA classifies medical devices into one of three classes: (i) Class I devices are relatively simple and can be manufactured and distributed with general controls; (ii) Class II devices are somewhat more complex and receive greater scrutiny from the FDA and have heightened regulatory requirements; and (iii) Class III devices are new, high risk devices, and frequently are permanently implantable or help sustain life and generally require a Pre-Market Approval, or PMA, by the FDA.

In the United States, a company generally can obtain permission to distribute a new medical device in one of two ways. The first applies to any device that is substantially equivalent to a device first marketed prior to May 1976, or to another device marketed after that date, but which was substantially equivalent to a pre-May 1976 device. These devices are either Class I or Class II devices. To obtain FDA clearance to distribute the medical device, a company generally must submit a 510(k) notification, and receive an FDA order finding substantial equivalence to a predicate device (pre-May 1976 device or post-May 1976 device that was substantially equivalent to a pre-May 1976 device) and permitting commercial distribution of that medical device for its intended use. A 510(k) notification must provide information supporting a claim of substantial equivalence to a single medical device, the predicate device. If clinical data from human experience are required to support the 510(k) notification, these data must be gathered in compliance with investigational device exemption, or IDE, regulations for investigations performed in the United States. The 510(k) process is normally used for products of the type that we are developing and propose to market and sell. The FDA review process for premarket notifications submitted pursuant to Section 510(k) of the FDCA takes, pursuant to statutory requirements, 90 days, but it can take substantially longer if the FDA has questions regarding the regulatory submission. It is possible for 510(k) clearance procedures to take from six to eighteen months, depending on the concerns raised by the FDA and the complexity of the device. There is no guarantee that the FDA will “clear” a medical device for marketing, in which case the device cannot be distributed in the United States. There is also no guarantee that the FDA will deem the applicable device subject to the 510(k) process, as opposed to the more time-consuming, resource-intensive and problematic PMA process described below.

The second, more comprehensive, approval process applies to a new device that is not substantially equivalent to a pre-1976 product or that is to be used in supporting or sustaining life or preventing impairment. These devices are normally Class III devices. For example, most implantable devices are subject to the approval process as a Class III device. Two steps of FDA approval are generally required before a company can market a product in the United States that is subject to approval, as opposed to clearance, as a Class III device. First, a company must comply with IDE regulations in connection with any human clinical investigation of the device. These regulations permit a company to undertake a clinical study of a “non-significant risk” device without formal FDA approval. Prior express FDA approval is required if the device is a significant risk device. Second, the FDA must approve the company’s PMA application, which contains, among other things, clinical information acquired under the IDE. Additionally, devices subject to PMA approval may be subject to a panel review to obtain marketing approval and are required to pass a factory inspection in accordance with the current “good manufacturing practices” standards in order to obtain approval. The FDA will approve the PMA application if it finds there is reasonable assurance that the device is safe and effective for its intended use. The PMA process takes substantially longer than the 510(k) process, approximately one to two years or more.

However, in some instances the FDA may find that a device is new and not substantially equivalent to a predicate device but is also not a high risk device as is generally the case with Class III PMA devices. In these instances FDA may allow a device to be down classified from Class III to Class I or II. The de novo classification option is an alternate pathway to classify novel devices of low to moderate risk that had automatically been placed in Class III after receiving a “not substantially equivalent,” or NSE, determination in response to a 510(k) notification. The regulations have also been amended to allow a sponsor to submit a de novo classification request to the FDA for novel low to moderate risk devices without first being required to submit a 510(k) application. These types of applications are referred to as “Evaluation of Automatic Class III Designation” or “de novo.” In instances where a device is deemed not substantially equivalent to a Class II predicate device, the candidate device may be filed as a de novo application which may lead to delays in regulatory decisions by the FDA. FDA review of a de novo application may lead the FDA to identify the device as either a Class I or II device and worthy of either an exempt or 510(k) regulatory pathway.

The Company believes the Senhance System and many related products are Class II devices as evidenced by the Company’s recently cleared 510(k) premarket notification. The Company intends to further develop the product line by adding additional instrumentation

5

and accessories for use with the Senhance System.  At this time, the Company believes that the items under development are Class II devices subject to 510(k) premarket notification. The FDA might find that the 510(k) submission does not provide the evidence required to prove that the additional instruments or accessories for use with the Senhance System are substantially equivalent to marketed Class II devices. If that were to occur, the Company would be required to undertake the more complex and costly PMA process or perhaps be considered for a de novo reclassification. For either the 510(k), de novo, or the PMA process, the FDA could require the Company to conduct clinical trials, which would take more time, cost more money and pose other risks and uncertainties.

Clinical studies conducted in the U.S. or used in any U.S. application on an unapproved medical device require approval from the FDA prior to initiation. Even when a clinical study has been approved by the FDA or deemed approved, the study is subject to factors beyond a manufacturer’s control, including, but not limited to, the fact that the institutional review board, or IRB, at a specified clinical site might not approve the study, might decline to renew approval, or might suspend or terminate the study before its completion. There is no assurance that a clinical study at any given site will progress as anticipated. In addition, there can be no assurance that the clinical study will provide sufficient evidence to assure the FDA that the product is safe and effective, a prerequisite for FDA approval of a PMA, or substantially equivalent in terms of safety and effectiveness to a predicate device, a prerequisite for clearance under Section 510(k). Even if the FDA approves or clears a device, it may limit its intended uses in such a way that manufacturing and distribution of the device may not be commercially feasible.

After clearance or approval to market is given, the FDA and foreign regulatory agencies, upon the occurrence of certain serious adverse events, are authorized under various circumstances to withdraw the clearance or approval of the device, or require changes to a device, its manufacturing process or its labeling or require additional proof that regulatory requirements have been met.

A manufacturer of a device approved through the PMA process is not permitted to make changes to the device which affect its safety or effectiveness without first submitting a supplement application to its PMA and obtaining FDA approval for that supplement, prior to marketing the modified device. In some instances, the FDA may require clinical trials to support a supplement application. A manufacturer of a device cleared through the 510(k) process must submit an additional premarket notification if it intends to make a change or modification in the device that could significantly affect the safety or effectiveness of the device, such as a significant change or modification in design, material, chemical composition, energy source, labeling or manufacturing process. Any change in the intended uses of a PMA device or a 510(k) device requires an approval supplement or new cleared premarket notification. Exported devices are subject to the regulatory requirements of each country to which the device is exported, as well as certain FDA export requirements.

Continuing FDA Regulation

After a device is placed on the market, numerous FDA and other regulatory requirements continue to apply. These include:

We are required to, and have, registered with the FDA as a medical device manufacturer. We must obtain all necessary permits and licenses to operate our business in all regions in which we do business. As manufacturers, we and our suppliers are subject to announced and unannounced inspections by the FDA to determine our compliance with the Quality System Regulation, or QSR, and other regulations.

In Europe, we need to comply with the requirements of the Medical Devices Directive, or MDD, and appropriately affix the CE Mark on our products to attest to such compliance. Our products marketed in the EU meet the “Essential Requirements” of the MDD relating to safety and performance. We have undergone verification of our regulatory compliance, or conformity assessment, by a notified body duly authorized by an EU country and must continue to do so as new products and changes to the products arise. The level of scrutiny of such

6

assessment depends on the regulatory class of the product. We are subject to continued surveillance by our notified body and will be required to report any serious adverse incidents to the appropriate authorities. We also must comply with additional requirements of individual countries in which our products are marketed. In the European Community, we are required to maintain certain quality system certifications in order to sell products. These regulations require us or our manufacturers to manufacture products and maintain documents in a prescribed manner with respect to design, manufacturing, testing, labeling and control activities.  As manufacturers, we and our suppliers are subject to announced and unannounced inspections by the European Notified Bodies.

Impact of Regulation

Failure to comply with the applicable regulatory requirements can result in enforcement action by the FDA and other international regulatory bodies, which may include, among other things, any of the following sanctions:

Further, the levels of revenues and profitability of medical device companies like us may be affected by the continuing efforts of government and third party payors to contain or reduce the costs of health care through various means. For example, in certain foreign markets, pricing or profitability of products is subject to governmental control. In the United States, there have been, and we expect that there will continue to be, a number of federal and state proposals to implement similar governmental controls.

Therefore, we cannot assure you that any of our products will be considered cost effective, or that, following any commercialization of our products, coverage and reimbursement will be available or sufficient to allow us to manufacture and sell them competitively and profitably.

Health Care Regulation

Our business activities are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which we conduct our business. Such laws include, without limitation, state and federal anti-kickback, fraud and abuse, false claims, privacy and security and physician payment transparency laws. If our operations are found to be in violation of any of such laws that apply to us, we may be subject to penalties, including, without limitation, civil and criminal penalties, damages, fines, the curtailment or restructuring of our operations, exclusion from participation in federal and state healthcare programs and imprisonment, any of which could adversely affect our ability to operate our business and our financial results.

In the United States, there have been, and we expect there to continue to be, a number of legislative and regulatory initiatives, at both the federal and state government levels, to change the healthcare system in ways that, if approved, could affect our ability to sell our products profitably. At the current time, our products are not defined as durable medical equipment. Non-DME devices used in surgical procedures are normally paid directly by the hospital or health care provider and not reimbursed separately by third-party payors. Instead, the hospital or health care provider is reimbursed based on the procedure performed and the inpatient or outpatient stay. As a result, these types of devices are subject to intense price competition that can place a small manufacturer at a competitive disadvantage as hospitals, ambulatory surgery centers and health care providers attempt to negotiate lower prices for products such as the ones we develop and sell.

In March 2010, the Patient Protection and Affordable Care Act (the “Affordable Care Act”) and the reconciliation law known as Health Care and Education Reconciliation Act (the “Reconciliation Act,” and, with the Affordable Care Act, the “2010 Health Care Reform Legislation”) were enacted into law. The constitutionality of the 2010 Health Care Reform Legislation was confirmed twice by the Supreme Court of the United States. Both Congressional leaders and President Trump have announced plans to repeal or modify the 2010 Health Care Reform Legislation.  At this time the Company is not certain as to the impact of federal health care legislation on its business.

The 2010 Health Care Reform Legislation subjects manufacturers of medical devices to an excise tax of 2.3% on certain U.S. sales of medical devices beginning in January 2013. This excise tax was suspended in December 2015 for two years, and again in January 2018 for an additional two years. If eventually implemented, this excise tax will likely increase our expenses in the future.

Further, the 2010 Health Care Reform Legislation includes the Open Payments Act (formerly referred to as the Physician Payments Sunshine Act), which, in conjunction with its implementing regulations, requires certain manufacturers of certain drugs, biologics, and devices that are reimbursed by Medicare, Medicaid and the Children’s Health Insurance Program to report annually certain payments or “transfers of value” provided to physicians and teaching hospitals and to report annually ownership and investment interests held by physicians and their immediate family members during the preceding calendar year. We have provided reports under the Open Payments Act to the Centers for Medicare & Medicaid Services since 2014. The failure to report appropriate data accurately, timely, and completely could subject us to significant financial penalties. Other countries and several states currently have similar laws and more may enact similar legislation.

International Regulation and Potential Impact

Through the Senhance Acquisition, the Company has expanded into international markets and intends to pursue continued expansion. Some of these markets maintain unique regulatory requirements outside of or in addition to those of the U.S. FDA and the European Union. The Senhance System is CE marked, which allows us to offer the product for sale in a number of jurisdictions, including select countries in Europe, the Middle East and Asia.  Due to the variations in regulatory requirements within territories, the Company may be required to perform additional safety or clinical testing or fulfill additional agency requirements for specific territories. The Company may also be required to apply for registration using third parties within those territories and may be dependent upon the third parties’ successful regulatory processes to file, register and list the product applications and associated labeling, which could lead to significant investments and resource use. These additional requirements may result in delays in international registrations and commercialization of our products in certain countries.

In addition, we are utilizing distributors and sales agents in various territories throughout Europe, the Middle East and Africa, and need to ensure that our activities, and the activities of our distributors and sales agents, are compliant with local law and U.S. laws governing the sales of medical devices.  The laws governing the registration, approval, clearance and sales of medical devices, such as the Senhance System, in multiple jurisdictions are complex, and the failure to comply with such laws in any given jurisdiction could subject us to financial penalties or suspension or termination of our ability to sell our products in the applicable jurisdiction.  

Employees

As of December 31, 2017, we had 121 employees, including 119 full time employees. The Company considers its relationships with its employees to be good.

We are currently highly dependent on the commercial success of a single product, the Senhance System.  We cannot give any assurance that the Senhance System can be successfully commercialized.  

We are currently highly dependent on the commercial success of the Senhance System, which is FDA cleared and CE marked. We began our selling efforts for the Senhance System in the fourth quarter of 2015 in Europe and in the fourth quarter of 2017 in the United States.  We have had limited commercial success to date.  We are still in the process of establishing our commercial infrastructure in the U.S.  We cannot assure you that we will be able to successfully commercialize the Senhance System, for a number of reasons, including, without limitation, failure in our sales and marketing efforts, the long sales cycle associated with the purchase of capital equipment, or the potential introduction by our competitors of more clinically effective or cost-effective alternatives.  Failure to successfully commercialize the Senhance System would have a material and adverse effect on our business.

The sales cycle for the Senhance System is lengthy and unpredictable, which will make it difficult for us to forecast revenue and increase the magnitude of quarterly fluctuations in our operating results.

Purchase of a surgical robotic system such as the Senhance System represents a capital purchase by hospitals and other potential customers.  The capital purchase nature of the transaction, the complexity of our product, the relative newness of surgical robotics and the competitive landscape requires us to spend substantial time and effort to assist potential customers in evaluating our robotic systems. We must communicate with multiple surgeons, administrative staff and executives within each potential customer in order to receive all approvals on behalf of such organizations. We may face difficulty identifying and establishing contact with such decision makers. Even after initial acceptance, the negotiation and documentation processes can be lengthy. Additionally, our customers may have strict limitations on spending depending on the current economic climate or trends in healthcare management.

We are also expanding the potential market for robotic surgical systems with our focus on laparoscopic surgery.  Such expansion requires a different sales and marketing approach than a focus on open procedures.  We expect our sales cycle to range between four to six quarters per sale.  Each sale could take longer. Any delay in completing sales in a particular quarter could cause our operating results to fall below expectations. We also expect such a lengthy sales cycle makes it more difficult for us to accurately forecast revenue in future periods and may cause revenues and operating results to vary significantly in future periods.  

Although we have expanded our commercial organization, we currently have limited marketing, sales and distribution capabilities. We are distributing our products through direct sales in the U.S. and select countries in Europe, and elsewhere through the use of independent contractor and distribution agreements with companies possessing established sales and marketing operations in the medical device industry.  There can be no assurance that we will be successful in building our sales capabilities. To the extent that we enter into distribution, co-promotion or other arrangements, our product revenue is likely to be lower than if we directly market or sell our products. In addition, any revenue we receive will depend in whole or in part upon the efforts of such third parties, which may not be successful and are generally not within our control. If we are unable to enter into such arrangements on acceptable terms or at all, we may not be able to successfully commercialize our products. If we are not successful in commercializing our existing and future products, either on our own or through collaborations with one or more third parties, our future product revenue will suffer and we may incur significant additional losses.

We have procedures in place to require our distributors and sales agents to comply with applicable laws and regulations governing the sales of medical devices in the jurisdictions where they operate.  Failure to meet such requirements could subject us to financial penalties or the suspension or termination of the ability to sell our products in such jurisdiction.  

The surgical robotics industry is increasingly competitive, which can negatively impact our commercial opportunities.

The life sciences industry is highly competitive, and we face significant competition from many medical device companies that are researching and marketing products designed to address minimally invasive and robotic-assisted surgery, including new entrants in the competitive market. We are currently commercializing the Senhance System in the U.S. with FDA 510(k) clearance, in Europe which accepts a CE Mark, the Middle East and selected countries in Asia and face significant competition in such markets.  Many of our competitors, including Intuitive Surgical, have significantly greater financial, manufacturing, marketing and product development resources than we do. Some of the medical device companies we compete with or expect to compete with include Johnson & Johnson, Medtronic plc, Applied Medical, Intuitive Surgical, Verb Surgical, Titan Medical and a number of minimally invasive surgical device and robotic surgical device manufacturers and providers of products and therapies that are designed to reduce the need for or attractiveness of surgical intervention. In addition, many other universities and private and public research institutions are or may become active in research involving surgical devices for minimally invasive and robotic-assisted surgery.

We are also expanding the potential market for robotic surgical systems with our focus on laparoscopic surgery.  Such expansion may lead to additional competition with companies with sufficiently higher resources than ours.

9

We believe that our ability to successfully compete will depend on, among other things:

If our competitors market products that are more effective, safer, easier to use or less expensive than our products or future products, or that reach the market sooner than our products, we may not achieve commercial success. In addition, the medical device industry is characterized by rapid technological change. It may be difficult for us to stay abreast of the rapid changes in each technology. If we fail to stay at the forefront of technological change, we may be unable to compete effectively. Technological advances or products developed by our competitors may render our technologies or products obsolete or less competitive.

We anticipate that the highly competitive surgical robotics environment can lead our competitors to attempt to slow or derail our commercial progress.  We are using our best efforts to enter the commercial markets effectively and efficiently while maintaining compliance with all regulatory and legal requirements.  Responding to the actions of our competitors will require the attention of our management and may distract the management team from its focus on our commercial operations and lead to increased costs of commercialization, which could have a negative impact on our financial position.

Fluctuations in foreign currency exchange rates may adversely affect our financial results.

We conduct operations in several different countries, including the U.S. and throughout Europe, and portions of our revenues, expenses, assets and liabilities are denominated in U.S. dollars, Euros, and other currencies. Since our consolidated financial statements are presented in U.S. dollars, we must translate revenues, income and expenses, as well as assets and liabilities, into U.S. dollars at exchange rates in effect during or at the end of each reporting period. We have not historically hedged our exposure to foreign currency fluctuations.  Accordingly, increases or decreases in the value of the U.S. dollar against the Euro and other currencies could materially affect our net operating revenues, operating income and the value of balance sheet items denominated in foreign currencies.

Our global operations expose us to additional risks and challenges associated with conducting business internationally.

The international expansion of our business may expose us to risks inherent in conducting foreign operations. These risks include:

10

The risks that we face in our international operations may continue to intensify as we further develop and expand our international operations.

As we ramp up our manufacturing capabilities we face risks arising from sole suppliers of components and our ability to meet delivery schedules for sales of our products.

The Senhance System is manufactured for us under contract by a third party manufacturer. We or our manufacturer acquire raw materials and components of the Senhance System from vendors, some of which are sole suppliers. Although we believe that we have the manufacturing and inventory reserves to meet our anticipated Senhance System sales for the foreseeable future, we are currently taking steps to develop redundant manufacturing and supply alternatives. We cannot assure you that we will be successful in developing these redundant supply and manufacturing capabilities. If we are not successful, our business operations could suffer.

Because our design, development and manufacturing capabilities are limited, we may rely on third parties to design, develop, manufacture or supply some of our products. An inability to find additional or alternate sources for these services and products could materially and adversely affect our financial condition and results of operations.

We have used third-party design and development sources to assist in the design and development of our medical device products. In the future, we may choose to use additional third-party sources for the design and development of our products. If these design and development partners are unable to provide their services in the timeframe or to the performance level that we require, we may not be able to establish a contract and obtain a sufficient alternative supply from another supplier on a timely basis and in the manner that we require.

Our products require precise, high quality manufacturing. We and our contract manufacturers will be subject to ongoing periodic unannounced inspection by the FDA and non-U.S. regulatory authorities to ensure strict compliance with the quality systems regulations, current “good manufacturing practices” and other applicable government regulations and corresponding standards. If we or our contract manufacturers fail to achieve and maintain high manufacturing standards in compliance with QSR, we may experience manufacturing errors resulting in patient injury or death, product recalls or withdrawals, delays or interruptions of production or failures in product testing or delivery, delay or prevention of filing or approval of marketing applications for our products, cost overruns or other problems that could seriously harm our business.

Any performance failure by us or on the part of our design and development partners or contract manufacturers could delay product development or regulatory clearance or approval of our products, or commercialization of our products and future products, depriving us of potential product revenue and resulting in additional losses. In addition, our dependence on any third party for design, development or manufacturing could adversely affect our future profit margins. Our ability to replace any then-existing manufacturer may be difficult because the number of potential manufacturers is limited and, in the case of Class III devices, the FDA must approve any replacement manufacturer before manufacturing can begin. It may be difficult or impossible for us to identify and engage a replacement manufacturer on acceptable terms in a timely manner, or at all.

11

Our stock price has been volatile and may experience additional fluctuation in the future.

The market price of our common stock has been, and may continue to be, highly volatile, and such volatility could cause the market price of our common stock to decrease and could cause you to lose some or all of your investment in our common stock.  During the two year period ended December 31, 2017, the market price of our common stock fluctuated from a high of $6.10 per share to a low of $0.45 per share. The market price of our common stock may continue to fluctuate significantly in response to numerous factors, some of which are beyond our control, such as:

Further, the stock market in general, and the market for medical device companies in particular, can experience extreme price and volume fluctuations. Market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in the value of our common stock and the loss of some or all of your investment.

We have a history of operating losses, and we may not be able to achieve or sustain profitability.

We have a limited operating history. We are not profitable and have incurred losses since our inception.   Our net loss for the year ended December 31, 2017 was $144.8 million, and our accumulated deficit as of December 31, 2017 was $447.6 million.  We believe that our existing cash and cash equivalents, together with cash received from sales of our products, will be sufficient to meet our anticipated cash needs for at least the next 12 months.  

We expect to continue to incur losses for the foreseeable future. We will continue to incur research and development and general and administrative expenses related to our operations, and expect to increase our sales and marketing expenses as we increase our sales and marketing activities for the Senhance System in jurisdictions where FDA clearance and CE marking provides authorization for commercial activities.  If our product candidates fail in development or do not gain regulatory clearance or approval, or if our products do not achieve market acceptance, we may never become profitable. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods.

We will require substantial additional funding in the future, which may not be available to us on acceptable terms, or at all.

We do not anticipate that the net proceeds of equity financings in 2017 will be sufficient to support development of our products and product candidates and provide us with the necessary resources to commercialize the Senhance System and other products through the lengthy sales cycle. While we are currently focused on commercialization of our Senhance System, we intend to advance multiple additional products through clinical and pre-clinical development in the future. We believe we will need to raise substantial additional capital in order to continue our operations and achieve our business objectives.

We have an effective shelf registration statement. As of December 31, 2017, we had $100 million available for future financings under such shelf registration statement.  Such capacity will expire in May 2020.  We cannot assure you that we will be successful in obtaining such additional financing on terms acceptable to the Company or at all.

12

Our future funding requirements will depend on many factors, including, but not limited to:

Until we generate a sufficient amount of revenue to finance our cash requirements, which may never occur, we expect to finance future cash needs primarily through public or private equity offerings, debt financings or strategic collaborations. We do not know whether additional funding will be available on acceptable terms, or at all. If we are not able to secure additional funding when needed, we may have to delay, reduce the scope of or eliminate one or more of our research and development programs. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution; and debt financing, if available, may involve restrictive covenants that limit our operations. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our products or grant licenses on terms that may not be favorable to us.

Our stockholders have experienced dilution of their percentage ownership of our stock and may experience additional dilution in the future.

We have raised significant capital through the issuance of our common stock and warrants and anticipate that we will need to raise substantial additional capital in order to continue our operations and achieve our business objectives. We have an effective shelf registration statement under which we have the current ability to raise up to $100 million through the issuance of equity or debt securities.  We cannot assure you that we will be able to sell shares or other securities in any offering at a price per share that is equal to or greater than the price per share paid by investors in previous offerings, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price per share in previous offerings. The future issuance of the Company’s equity securities will further dilute the ownership of our outstanding common stock.  The market price of our common stock has been, and may continue to be, highly volatile, and such volatility could cause the market price of our common stock to decrease and could cause you to lose some or all of your investment in our common stock.

Sales by stockholders of substantial amounts of our shares of common stock, the issuance of new shares of common stock by us or the perception that these sales may occur in the future could materially and adversely affect the market price of our common stock.

As of December 31, 2017, our directors, executive officers, principal stockholders and affiliated entities beneficially owned, in the aggregate, approximately 25% of our outstanding voting securities. As a result, if some or all of them acted together, they would have the ability to exert substantial influence over the election of our board of directors and the outcome of issues requiring approval by our stockholders. This concentration of ownership may also have the effect of delaying or preventing a change in control of the Company that may be favored by other stockholders. This could prevent transactions in which stockholders might otherwise recover a premium for their shares over current market prices.

13

The exercise of our outstanding options and warrants will dilute stockholders and could decrease our stock price.

The existence of our outstanding options and warrants, including the outstanding Series B Warrants, may adversely affect our stock price due to sales of a large number of shares or the perception that such sales could occur. These factors also could make it more difficult to raise funds through future offerings of common stock or warrants, and could adversely impact the terms under which we could obtain additional equity capital. Exercise of outstanding options and warrants, or any future issuance of additional shares of common stock or other equity securities, including but not limited to options, warrants or other derivative securities convertible into our common stock, may result in significant dilution to our stockholders and may decrease our stock price.

If we default on our existing indebtedness, such default would affect our financial condition.

We are party with Innovatus Life Sciences Lending Fund I, LP, or the Lender, and jointly and severally liable with certain of our U.S. subsidiaries for $14.0 million of outstanding debt under term loans issued under our Loan and Security Agreement, or the Innovatus Loan Agreement. The maturity date of the outstanding term loan is May 10, 2021.  If we were to become unable to pay, when due, the principal of, interest on, or other amounts due in respect of, our indebtedness, our financial condition would be adversely affected.  Further, under the Innovatus Loan Agreement, we are subject to certain restrictive covenants that, among other things, subject to exceptions, restrict the Company’s ability to do the following things: declare dividends or redeem or repurchase equity interests; incur additional liens; make loans and investments; incur additional indebtedness; engage in mergers, acquisitions, and asset sales; transact with affiliates; undergo a change in control; add or change business locations; and engage in businesses that are not related to its existing business. If we breach any of these restrictive covenants or are unable to pay our indebtedness under the Innovatus Loan Agreement when due, this could result in a default under the Innovatus Loan Agreement. In such event, the Lender may elect (after the expiration of any applicable notice or grace periods) to declare all outstanding borrowings, together with accrued and unpaid interest and other amounts payable under the Innovatus Loan Agreement, to be immediately due and payable. Any such occurrence would have an adverse impact on our financial condition. The Company’s obligations under the Innovatus Loan Agreement are secured by a security interest in all of the assets of the Company and its current and future domestic and material foreign subsidiaries, including a security interest in the intellectual property.  

We issued 24,900,000 Series A Warrants and 24,900,000 Series B Warrants in May 2017; the outstanding warrants must be revalued each reporting period.  In addition, we owe contingent consideration to Sofar under the Purchase Agreement that is also revalued each reporting period.  Such assessments involve the use of estimates that could later be found to differ materially from actual results.

On April 28, 2017, we sold 24.9 million units, each consisting of one share of common stock, a Series A warrant to purchase one share of common stock, and a Series B warrant to purchase 0.75 shares of common stock, at a public offering price of $1.00 per unit for aggregate gross proceeds of $24.9 million in an underwritten firm commitment public offering.  As of December 31, 2017, all Series A warrants were exercised. At December 31, 2017, Series B Warrants to acquire 9.8 million shares of common stock were outstanding. The outstanding Series B Warrants contain provisions, often referred to as “down-round protection” that may lead to adjustment of the exercise price and number of underlying warrant shares with respect to future issuances by the Company of its securities, including its common stock or convertible securities or debt securities.  In addition, the third tranche of the contingent consideration to be paid to Sofar under the Purchase Agreement remains outstanding, to be paid if the designated milestone is met.  

The Series B Warrants and the contingent consideration are each recorded as a liability on our financial statements, and we are required to revalue each of the outstanding Series B Warrants and the contingent consideration at each reporting period.  Such revaluations necessarily involve the use of estimates, assumptions, probabilities and application of complex accounting principles.  Actual value at the time the Series B Warrants are exercised or the contingent consideration paid could vary significantly from the value assigned to such liabilities on a quarterly basis. We cannot assure you that the revaluation of the Series B Warrants and contingent consideration will equal the value in the future, and know that the actual value could be significantly different, which could have a material adverse effect on us.  

We sold our SurgiBot System assets in 2017, and we may not obtain the royalty income we anticipate from such sale.

In December 2017, we transferred ownership of the SurgiBot System assets to GBIL. The agreements provide rights to the purchaser to manufacture, or have manufactured, the SurgiBot System in China, and provides exclusive distribution rights to the Chinese market.  The agreement provides us with minimum royalties of $14 million over a future five-year period.  If the buyer is not successful in gaining Chinese regulatory approval or marketing the SurgiBot System, we will only receive such minimum royalties, decreasing the return on the funds expended in the development of the SurgiBot System.  

14

Our commercial success depends significantly on our ability to operate without infringing the patents and other proprietary rights of third parties.

Other entities may have or obtain patents or proprietary rights that could limit our ability to manufacture, use, sell, offer for sale or import products or impair our competitive position. In addition, to the extent that a third party develops new technology that covers our products, we may be required to obtain licenses to that technology, which licenses may not be available or may not be available on commercially reasonable terms, if at all. If licenses are not available to us on acceptable terms, we will not be able to market the affected products or conduct the desired activities, unless we challenge the validity, enforceability or infringement of the third-party patent or circumvent the third-party patent, which would be costly and would require significant time and attention of our management. Third parties may have or obtain valid and enforceable patents or proprietary rights that could block us from developing products using our technology. Our failure to obtain a license to any technology that we require may materially harm our business, financial condition and results of operations.

If we become involved in patent litigation or other proceedings related to a determination of rights, we could incur substantial costs and expenses, substantial liability for damages or be required to stop our product development and commercialization efforts, any of which could materially adversely affect our liquidity, business prospects and results of operations.

Third parties may sue us for infringing their patent rights. Likewise, we may need to resort to litigation to enforce a patent issued or licensed to us or to determine the scope and validity of proprietary rights of others. In addition, a third party may claim that we have improperly obtained or used its confidential or proprietary information. Furthermore, in connection with our third-party license agreements, we generally have agreed to indemnify the licensor for costs incurred in connection with litigation relating to intellectual property rights. The cost to us of any litigation or other proceeding relating to intellectual property rights, even if resolved in our favor, could be substantial, and the litigation would divert our management’s efforts. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. Uncertainties resulting from the initiation and continuation of any litigation could limit our ability to continue our operations.

If any parties successfully claim that our creation or use of proprietary technologies infringes upon their intellectual property rights, we might be forced to pay damages, potentially including treble damages, if we are found to have willfully infringed on such parties’ patent rights. In addition to any damages we might have to pay, a court could require us to stop the infringing activity or obtain a license. Any license required under any patent may not be made available on commercially acceptable terms, if at all. In addition, such licenses are likely to be non-exclusive and, therefore, our competitors may have access to the same technology licensed to us. If we fail to obtain a required license and are unable to design around a patent, we may be unable to effectively market some of our technology and products, which could limit our ability to generate revenues or achieve profitability and possibly prevent us from generating revenue sufficient to sustain our operations.

For our Senhance System, we rely on our license from the European Union, and any loss of our rights under such license agreement, or failure to properly prosecute, maintain or enforce the patent applications underlying such license agreement, could materially adversely affect our business prospects for the Senhance System.

Some of the patents and patent applications in our patent portfolio related to the Senhance System are licensed to TransEnterix Italia under a license agreement with the European Union. Presently, we rely on such licensed technology for our Senhance System products and may license additional technology from the European Union or other third parties in the future. The EU license agreement gives us rights for the commercial exploitation of the licensed patents, patent applications and know-how, subject to certain provisions of the license agreement. Failure to comply with these provisions could result in the loss of our rights under the EU license agreement. Our inability to rely on these patents and patent applications which are the basis of certain aspects of our Senhance System technology would have an adverse effect on our business.

Further, our success will depend in part on the ability of us, the European Union and other third-party licensors to obtain, maintain and enforce patent protection for our licensed intellectual property and, in particular, those patents to which we have secured exclusive rights. We, the European Union or other third-party licensors may not successfully prosecute the patent applications which are licensed to us, may fail to maintain these patents, and may determine not to pursue litigation against other companies that are infringing these patents, or may pursue such litigation less aggressively than necessary to obtain an acceptable outcome from any such litigation. Without protection for the intellectual property we have licensed, other companies might be able to offer substantially identical products for sale, which could materially adversely affect our competitive business position, business prospects and results of operations.

If we or our licensors are unable to protect the confidentiality of our proprietary information and know-how, the value of our technology and products could be adversely affected.

In addition to patent protection, we also rely on other proprietary rights, including protection of trade secrets, know-how and confidential and proprietary information. To maintain the confidentiality of trade secrets and proprietary information, we will seek to

15

enter into confidentiality agreements with our employees, consultants and collaborators upon the commencement of their relationships with us. These agreements generally require that all confidential information developed by the individual or made known to the individual by us during the course of the individual’s relationship with us be kept confidential and not disclosed to third parties. Our agreements with employees also generally provide and will generally provide that any inventions conceived by the individual in the course of rendering services to us shall be our exclusive property. However, we may not obtain these agreements in all circumstances, and individuals with whom we have these agreements may not comply with their terms. In the event of unauthorized use or disclosure of our trade secrets or proprietary information, these agreements, even if obtained, may not provide meaningful protection, particularly for our trade secrets or other confidential information. To the extent that our employees, consultants or contractors use technology or know-how owned by third parties in their work for us, disputes may arise between us and those third parties as to the rights in related inventions. Adequate remedies may not exist in the event of unauthorized use or disclosure of our confidential information. The disclosure of our trade secrets would impair our competitive position and may materially harm our business, financial condition and results of operations.

If we are unable to obtain and enforce patent protection for our products, our business could be materially harmed.

Our success depends, in part, on our ability to protect proprietary methods and technologies that we develop or license under the patent and other intellectual property laws of the United States and other countries, so that we can prevent others from unlawfully using our inventions and proprietary information. However, we may not hold proprietary rights to some patents required for us to commercialize our proposed products. Because certain U.S. patent applications are confidential until patents issue, such as applications filed prior to November 29, 2000, or applications filed after such date which will not be filed in foreign countries, third parties may have filed patent applications for technology covered by our pending patent applications without our being aware of those applications, and our patent applications may not have priority over those applications. For this and other reasons, we or our third-party collaborators may be unable to secure desired patent rights, thereby losing desired exclusivity. If licenses are not available to us on acceptable terms, we will not be able to market the affected products or conduct the desired activities, unless we challenge the validity, enforceability or infringement of the third-party patent or otherwise circumvent the third-party patent.

Our strategy depends on our ability to promptly identify and seek patent protection for our discoveries. In addition, we may rely on third-party collaborators to file patent applications relating to proprietary technology that we develop jointly during certain collaborations. The process of obtaining patent protection is expensive and time-consuming. If our present or future collaborators fail to file and prosecute all necessary and desirable patent applications at a reasonable cost and in a timely manner, our business will be adversely affected. Despite our efforts and the efforts of our collaborators to protect our proprietary rights, unauthorized parties may be able to develop and use information that we regard as proprietary.

The issuance of a patent provides a presumption, but does not guarantee that it is valid. Any patents we have obtained, or obtain in the future, may be challenged or potentially circumvented. Moreover, the United States Patent and Trademark Office, or the USPTO, may commence interference proceedings involving our patents or patent applications. Any such challenge to our patents or patent applications would be costly, would require significant time and attention of our management and could have a material adverse effect on our business. In addition, future court decisions may introduce uncertainty in the enforceability or scope of any patent, including those owned by medical device companies.

Our pending patent applications may not result in issued patents. The patent position of medical device companies, including ours, is generally uncertain and involves complex legal and factual considerations. The standards that the USPTO and its foreign counterparts use to grant patents are not always applied predictably or uniformly and can change. There is also no uniform, worldwide policy regarding the subject matter and scope of claims granted or allowable in medical device patents. Accordingly, we do not know the degree of future protection for our proprietary rights or the breadth of claims that will be allowed in any patents issued to us or to others. The legal systems of certain countries do not favor the aggressive enforcement of patents, and the laws of foreign countries may not protect our rights to the same extent as the laws of the United States. Therefore, the enforceability or scope of our owned or licensed patents in the United States or in foreign countries cannot be predicted with certainty, and, as a result, any patents that we own or license may not provide sufficient protection against competitors. We may not be able to obtain or maintain patent protection for our pending patent applications, those we may file in the future, or those we may license from third parties.

We cannot assure you that any patents that will issue, that may issue or that may be licensed to us will be enforceable or valid or will not expire prior to the commercialization of our products, thus allowing others to more effectively compete with us. Therefore, any patents that we own or license may not adequately protect our future products.

16

Even if we obtain regulatory clearances or approvals for our products, the terms thereof and ongoing regulation of our products may limit how we manufacture and market our products, which could materially impair our ability to generate anticipated revenues.

Once regulatory clearance or approval has been granted, the cleared or approved product and its manufacturer are subject to continual review. Any cleared or approved product may be promoted only for its indicated uses. In addition, if the FDA or other non-U.S. regulatory authorities clear or approve any of our products, the labeling, packaging, adverse event reporting, storage, advertising and promotion for the product will be subject to extensive regulatory requirements. We and any outsourced manufacturers of our products are also required to comply with the FDA’s Quality System Regulation, or similar requirements of non-U.S. regulatory authorities which includes requirements relating to quality control and quality assurance, as well as the corresponding maintenance of records and documentation as well as other quality system requirements and regulations from non-U.S. regulatory authorities. Further, regulatory agencies must approve our manufacturing facilities for Class III devices before they can be used to manufacture our products, and all manufacturing facilities are subject to ongoing regulatory inspection. If we fail to comply with the regulatory requirements of the FDA, either before or after clearance or approval, or other non-U.S. regulatory authorities, or if previously unknown problems with our products, manufacturers or manufacturing processes are discovered, we could be subject to administrative or judicially imposed sanctions, including:

Any of these sanctions could have a material adverse effect on our reputation, business, results of operations and financial condition. Furthermore, our key component suppliers may not currently be or may not continue to be in compliance with all applicable regulatory requirements, which could result in our failure to produce our products on a timely basis and in the required quantities, if at all.

In addition, the FDA and other non-U.S. regulatory authorities may change their policies and additional regulations may be enacted that could prevent or delay regulatory clearance or approval of our products. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are not able to maintain regulatory compliance, we would likely not be permitted to market our future products and we may not achieve or sustain profitability.

17

The regulatory approval and clearance processes are expensive, time-consuming and uncertain and may prevent us from obtaining approvals or clearances, as the case may be, for the commercialization of some or all of our products.

Regulatory approval of a PMA, PMA supplement or clearance pursuant to a 510(k) premarket notification is not guaranteed, and the approval or clearance process, as the case may be, is expensive, uncertain and may, especially in the case of the PMA application, take several years. The FDA also has substantial discretion in the medical device clearance process or approval process. Despite the time and expense exerted, failure can occur at any stage, and we could encounter problems that cause us to repeat or perform additional development, standardized testing, pre-clinical studies and clinical trials. The number of pre-clinical studies and clinical trials that will be required for FDA clearance or approval varies depending on the medical device candidate, the disease or condition that the medical device candidate is designed to address, and the regulations applicable to any particular medical device candidate. The FDA or other non-U.S. regulatory authorities can delay, limit or deny clearance or approval of a medical device candidate for many reasons, including:

The laws governing the regulatory approval or clearance pathways in jurisdictions outside of the United States are complex.  We need to ensure that our activities, and the activities of our distributors and agents, comply with such laws.  If we do not comply with such laws, we may not be able to sell our products, including the Senhance System, in all jurisdictions we have targeted, which could have an adverse effect on our business operations and financial condition.  

Once our products are cleared or approved, modifications to our products may require new 510(k) clearances, premarket approvals or new or amended CE Certificates of Conformity, and may require us to cease marketing or recall the modified products until clearances, approvals or the relevant CE Certificates of Conformity are obtained.

Any modification to a 510(k)-cleared device that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, design, or manufacture, requires a new 510(k) clearance or, possibly, a PMA. The FDA requires every manufacturer to make this determination in the first instance, but the FDA may review such determinations. The FDA may not agree with our decisions regarding whether new clearances or approvals are necessary. If the FDA disagrees with our determinations for any future changes, or prior changes to previously marketed products, as the case may be, we may be required to cease marketing or to recall the modified products until we obtain clearance or approval, and we may be subject to significant regulatory fines or penalties.

Furthermore, the FDA’s ongoing review of the 510(k) program may make it more difficult for us to make modifications to our products, either by imposing more strict requirements on when a new 510(k) for a modification to a previously cleared product must be submitted, or applying more onerous review criteria to such submissions. In October 2017, the FDA issued guidance documents addressing when to submit a new 510(k) due to modifications to 510(k) cleared products and the criteria for evaluating substantial equivalence. The interpretation of the guidance document by the FDA staff could lead to instances where the FDA disagrees with the Company’s decision regarding a change, and could result in warning letters and other enforcement actions.

Even after clearance or approval for our products is obtained, we are subject to extensive post-market regulation by the FDA. Our failure to meet strict regulatory requirements could require us to pay fines, incur other costs or even close our facilities.

Even after we have obtained the proper regulatory clearance or approval to market a product, the FDA has the power to require us to conduct post-market studies. These studies can be very expensive and time-consuming to conduct. Failure to complete such studies in a timely manner could result in the revocation of clearance or approval and the recall or withdrawal of the product, which could prevent us from generating sales from that product in the United States. The FDA has broad enforcement powers, and any regulatory enforcement actions or inquiries, or other increased scrutiny on us, could dissuade some surgeons from using our products and adversely affect our reputation and the perceived safety and efficacy of our products.

18

We are also required to comply with the FDA’s QSR, which covers the methods used in, and the facilities and controls used for, the design, manufacture, quality assurance, labeling, packaging, sterilization, storage, shipping, installation and servicing of our marketed products. The FDA enforces the QSR through periodic announced and unannounced inspections of manufacturing facilities. In addition, in the future, regulatory authorities and/or customers may require specific packaging of sterile products, which could increase our costs and the price of our products. Later discovery of previously unknown problems with our products, including unanticipated adverse events or adverse events of unanticipated severity or frequency, manufacturing problems, or failure to comply with regulatory requirements such as QSR, may result in changes to labeling, restrictions on such products or manufacturing processes, withdrawal of the products from the market, voluntary or mandatory recalls, a requirement to repair, replace or refund the cost of any medical device we manufacture or distribute, fines, suspension of regulatory approvals, product seizures, injunctions or the imposition of civil or criminal penalties which would adversely affect our business, operating results and prospects.

If one of our products, or a malfunction of one of our products, causes or contributes to a death or a serious injury, we will be subject to medical device reporting regulations, which can result in voluntary corrective actions or agency enforcement actions.

Under the FDA’s medical device reporting, or MDR, regulations, we are required to report to the FDA any incident in which our product may have caused or contributed to a death or serious injury or in which our product malfunctioned and, if the malfunction were to recur, would likely cause or contribute to death or serious injury. Repeated product malfunctions may result in a voluntary or involuntary product recall, which could divert managerial and financial resources, impair our ability to manufacture our products in a cost-effective and timely manner, and have an adverse effect on our reputation, results of operations and financial condition. We are also required to follow detailed recordkeeping requirements for all firm-initiated medical device corrections and removals, and to report such corrective and removal actions to the FDA if they are carried out in response to a risk to health and have not otherwise been reported under the MDR regulations.

All manufacturers bringing medical devices to market in the European Economic Area, or EEA, are legally bound to report any incident that led or might have led to the death or serious deterioration in the state of health of a patient, user or other person, and which the manufacturer’s device is suspected to have caused, to the competent authority in whose jurisdiction the incident occurred. In such case, the manufacturer must file an initial report with the relevant competent authority, which would be followed by further evaluation or investigation of the incident and a final report indicating whether further action is required.  Any adverse event involving our products could result in future voluntary corrective actions, such as recalls or customer notifications, or agency action, such as inspection or enforcement action. Adverse events involving our products have been reported to us in the past, and we cannot guarantee that they will not occur in the future. Any corrective action, whether voluntary or involuntary, will require the dedication of our time and capital, distract management from operating our business and may harm our reputation and financial results.

A recall of our products, either voluntarily or at the direction of the FDA or another governmental authority, or the discovery of serious safety issues with our products, could have a significant adverse impact on us.

The FDA and similar foreign governmental authorities such as the competent authorities of the EEA countries have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture or in the event that a product poses an unacceptable risk to health. Manufacturers may, under their own initiative, recall a product if any material deficiency in a device is found. A government-mandated or voluntary recall by us or one of our distributors could occur as a result of an unacceptable risk to health, component failures, manufacturing errors, design or labeling defects or other deficiencies and issues.

Any future recalls of any of our products would divert managerial and financial resources and could have an adverse effect on our reputation, results of operations and financial condition, which could impair our ability to produce our products in a cost-effective and timely manner in order to meet our customers’ demands. We may also be required to bear other costs or take other actions that may have a negative impact on our future sales and our ability to generate profits.

U.S. legislative or FDA regulatory reforms may make it more difficult and costly for us to obtain regulatory approval of our product candidates and to manufacture, market and distribute our products after approval is obtained.

Legislative changes could significantly alter the statutory provisions governing the regulatory approval, manufacture and marketing of regulated products. In addition, FDA regulations and guidance could be revised or reinterpreted by the FDA in ways that could significantly affect our business and our products. Any new regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of future products. It is impossible to predict whether legislative changes will be enacted or FDA regulations, guidance or interpretations changed, and what the impact of such changes, if any, may be.

19

Even if we receive regulatory clearance or approval to market our products, the market may not be receptive to our products, which could undermine our financial viability.

Even if our products obtain regulatory clearance or approval, resulting products may not gain market acceptance among physicians, patients, health care payors and/or the medical community. We have experienced minimal sales of our Senhance System, to date. We believe that the degree of market acceptance will depend on a number of factors, including:

If applicable, availability of coverage and reimbursement from government and other third-party payors can also impact the acceptance of our product offerings.

If we fail to attract and retain key management and professional personnel, we may be unable to successfully commercialize or develop our products.

We will need to effectively manage our operational, sales and marketing, development and other resources in order to successfully pursue our commercialization and research and development efforts for our existing and future products. Our success depends on our continued ability to attract, retain and motivate highly qualified personnel.   If we are not successful in retaining and recruiting highly qualified personnel, our business may be harmed as a result.

We may be subject, directly or indirectly, to federal and state anti-kickback, fraud and abuse, false claims, privacy and security and physician payment transparency laws. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.

Our business activities are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which we conduct our business. Such laws include, without limitation, state and federal anti-kickback, fraud and abuse, false claims, privacy and security and physician payment transparency laws. If our operations are found to be in violation of any of such laws that apply to us, we may be subject to penalties, including, without limitation, civil and criminal penalties, damages, fines, the curtailment or restructuring of our operations, exclusion from participation in federal and state healthcare programs and imprisonment, any of which could adversely affect our ability to operate our business and our financial results.

Current legislation and future legislative or regulatory reform of the health care system may affect our ability to sell our products profitably.

In the United States, there have been, and we expect there to continue to be, a number of legislative and regulatory initiatives, at both the federal and state government levels, to change the healthcare system in ways that, if approved, could affect our ability to sell our products profitably. While many of the proposed policy changes require congressional approval to implement, we cannot assure you that reimbursement payments under governmental and private third-party payor programs to health care providers will remain at levels comparable to present levels or will be sufficient to cover the costs allocable to patients eligible for reimbursement under these programs. Any changes that lower reimbursement rates under Medicare, Medicaid or private payor programs could negatively affect our business.

To the extent that any of our products are deemed to be durable medical equipment, or DME, they may be subject to distribution under Medicare’s Competitive Acquisition regulations, which could adversely affect the amount that we can seek from payors. Non‑DME devices used in surgical procedures are normally paid directly by the hospital or health care provider and not reimbursed separately by third-party payors. As a result, these types of devices are subject to intense price competition that can place a small manufacturer at a competitive disadvantage as hospitals and health care providers attempt to negotiate lower prices for products such as the ones we develop and sell.

20

With the continued uncertainty regarding the status of the 2010 Health Care Reform Legislation, at this time, the Company is not certain as to the impact of federal health care legislation on its business.  

The 2010 Health Care Reform Legislation subjects manufacturers of medical devices to an excise tax of 2.3% on certain U.S. sales of medical devices beginning in January 2013. This excise tax was suspended in December 2017 for two additional years, however, if eventually implemented, this excise tax will likely increase our expenses in the future.

Further, the 2010 Health Care Reform Legislation includes the Open Payments Act (formerly referred to as the Physician Payments Sunshine Act), which, in conjunction with its implementing regulations, requires certain manufacturers of certain drugs, biologics, and devices that are reimbursed by Medicare, Medicaid and the Children’s Health Insurance Program to report annually certain payments or “transfers of value” provided to physicians and teaching hospitals and to report annually ownership and investment interests held by physicians and their immediate family members during the preceding calendar year. We provided reports under the Open Payments Act to the Centers for Medicare & Medicaid Services, or CMS. The failure to report appropriate data accurately, timely, and completely could subject us to significant financial penalties. Other countries and several states currently have similar laws and more may enact similar legislation.

We are unable to predict what additional legislation or regulation relating to the health care industry or third-party coverage and reimbursement may be enacted in the future or what effect such legislation or regulation would have on our business. Any cost containment measures or other health care system reforms that are adopted could have a material and adverse effect on our ability to commercialize our existing and future products successfully.

Because our design, development and manufacturing capabilities are limited, we may rely on third parties to design, develop, manufacture or supply some of our products. An inability to find additional or alternate sources for these services and products could materially and adversely affect our financial condition and results of operations.

We have used third-party design and development sources to assist in the design and development of our medical device products. In the future, we may choose to use additional third-party sources for the design and development of our products. If these design and development partners are unable to provide their services in the timeframe or to the performance level that we require, we may not be able to establish a contract and obtain a sufficient alternative supply from another supplier on a timely basis and in the manner that we require.

Our products require precise, high quality manufacturing. We and our contract manufacturers will be subject to ongoing periodic unannounced inspection by the FDA and non-U.S. regulatory authorities to ensure strict compliance with the quality systems regulations, current “good manufacturing practices” and other applicable government regulations and corresponding standards. If we or our contract manufacturers fail to achieve and maintain high manufacturing standards in compliance with QSR, we may experience manufacturing errors resulting in patient injury or death, product recalls or withdrawals, delays or interruptions of production or failures in product testing or delivery, delay or prevention of filing or approval of marketing applications for our products, cost overruns or other problems that could seriously harm our business.

Any performance failure by us or on the part of our design and development partners or contract manufacturers could delay product development or regulatory clearance or approval of our products, or commercialization of our products and future products, depriving us of potential product revenue and resulting in additional losses. In addition, our dependence on any third party for design, development or manufacturing could adversely affect our future profit margins. Our ability to replace any then-existing manufacturer may be difficult because the number of potential manufacturers is limited and, in the case of Class III devices, the FDA must approve any replacement manufacturer before manufacturing can begin. It may be difficult or impossible for us to identify and engage a replacement manufacturer on acceptable terms in a timely manner, or at all.

We may become subject to potential product liability claims, and we may be required to pay damages that exceed our insurance coverage.

Our business exposes us to potential product liability claims that are inherent in the design, testing, manufacture, sale and distribution of our products and each of our product candidates that we are seeking to introduce to the market. Surgical medical devices involve significant risks of serious complications, including bleeding, nerve injury, paralysis, infection, and even death. Any product liability claim brought against us, with or without merit, could result in the increase of our product liability insurance rates or in our inability to secure coverage in the future on commercially reasonable terms, if at all. In addition, if our product liability insurance proves to be inadequate to pay a damage award, we may have to pay the excess of this award out of our cash reserves, which could significantly harm our financial condition. If longer-term patient results and experience indicate that our products or any component of a product causes tissue damage, motor impairment or other adverse effects, we could be subject to significant liability. A product liability claim, even one without merit, could harm our reputation in the industry, lead to significant legal fees, and result in the diversion of management’s attention from managing our business.

The bid prices represent inter-dealer transactions, without adjustments for retail mark-ups, mark-downs or commissions and may not necessarily represent actual transactions.

As of March 1, 2018, there were approximately 228 record holders of our common stock (counting all shares held in single nominee registration as one stockholder).

We paid no dividends or made any other distributions in respect of our common stock during our fiscal years ended December 31, 2017, 2016 and 2015, and we have no plans to pay any dividends or make any other distributions in the future. In addition, the terms of the Innovatus Loan Agreement prohibit the Company from paying any dividends without the consent of the Lender.

Securities Authorized for Issuance Under Equity Compensation Plans.

The Company currently has one equity compensation plan under which it makes awards, the TransEnterix, Inc. Amended and Restated Incentive Compensation Plan, (the “Plan”). The Plan was originally approved by the Board of Directors and adopted by the majority of our stockholders on November 13, 2007, and amended and restated and approved by the Board of Directors and approved by the majority of our stockholders on May 7, 2015 to increase the number of shares of common stock authorized under the Plan to 11,940,000 shares, and to make other changes. The Plan was amended on June 8, 2016 to increase the number of shares reserved for issuance under the Plan to 18,940,000 shares. The Plan was amended on May 25, 2017 to increase the number of shares reserved for issuance under the Plan to 25,940,000 shares. The Plan is used for plan-based awards for officers, other employees, consultants, advisors and non-employee directors. In connection with the 2013 merger transaction with SafeStitch Medical, Inc., or the Merger, we assumed all of the options that were issued and outstanding immediately prior to the Merger as issued by TransEnterix Surgical, and adjusted based on the Merger at the exchange ratio, which are now exercisable for approximately 1,203,825 shares of common stock. Such options were granted under the TransEnterix, Inc. 2006 Stock Plan (the “2006 Plan”) which was assumed by the Company in the Merger. The 2006 Plan is maintained solely for the purpose of the stock options granted under such 2006 Plan that remain outstanding; no future awards are authorized to be made under the 2006 Plan.

Overview

TransEnterix is a medical device company that is digitizing the interface between the surgeon and the patient to improve minimally invasive surgery by addressing the clinical and economic challenges associated with current laparoscopic and robotic options in today's value-based healthcare environment. The Company is focused on the commercialization of the Senhance™ Surgical System, which digitizes laparoscopic minimally invasive surgery. The system allows for robotic precision, haptic feedback, surgeon camera control via eye sensing and improved ergonomics while offering responsible economics.

The Senhance System has been granted a CE Mark in Europe for laparoscopic abdominal and pelvic surgery, as well as limited thoracic operations excluding cardiac and vascular surgery. In April 2017, the Company submitted a 510(k) application to the FDA for the Senhance System. On October 13, 2017, the Company received 510(k) clearance from the FDA for use in laparoscopic colorectal and gynecologic surgery.  These indications cover 23 procedures, including benign and oncologic procedures.  We anticipate expanding the indications for use in the middle of 2018. The Senhance System is available for sale in the U.S., the EU and select other countries.

The Senhance System is a multi-port robotic surgery system which allows multiple robotic arms to control instruments and a camera. The system features advanced technology to enable surgeons with haptic feedback and the ability to move the camera via eye movement. The system replicates laparoscopic motion that is familiar to experienced surgeons, and integrates three-dimensional high definition vision technology. The Senhance System also offers responsible economics to hospitals by offering robotic technology with reusable instruments thereby reducing additional costs per surgery when compared to other robotic solutions.

The Company has also developed the SurgiBot System, a single-port, robotically enhanced laparoscopic surgical platform. On December 18, 2017, the Company announced that it had entered into an agreement with Great Belief International Limited, or GBIL, to advance the SurgiBot System towards global commercialization.  The agreement transfers ownership of the SurgiBot System assets, while the Company retains the option to distribute or co-distribute the SurgiBot System outside of China. Upon completion of the transfer of all SurgiBot System assets, GBIL will have the SurgiBot System manufactured in China and obtain Chinese regulatory clearance from the China Food and Drug Administration, or CFDA, while entering into a nationwide distribution agreement with China National Scientific and Instruments and Materials Company, or CSIMC, for the Chinese market.  The agreement provides the Company with proceeds of at least $29 million, of which $7.5 million was received in December 2017. An additional $7.5 million is expected to be received by March 31, 2018, including a $3.0 million equity investment at $2.33 per share. The remaining $14 million, representing minimum royalties, will be paid beginning at the earlier of receipt of Chinese regulatory approval or five years.

We believe that future outcomes of minimally invasive surgery will be enhanced through our combination of more advanced tools and robotic functionality, which are designed to: (i) empower surgeons with improved precision, dexterity and visualization; (ii) improve patient satisfaction and enable a desirable post-operative recovery; and (iii) provide a cost-effective robotic system, compared to existing alternatives today, for a wide range of clinical applications. Our strategy is to focus on the commercialization and further development of the Senhance System.

From our inception, we devoted a substantial percentage of our resources to research and development and start-up activities, consisting primarily of product design and development, clinical studies, manufacturing, recruiting qualified personnel and raising capital.

Since inception, we have been unprofitable. As of December 31, 2017, we had an accumulated deficit of $447.6 million.

We expect to continue to invest in research and development and sales and marketing and increase selling, general and administrative expenses as we grow. As a result, we will need to generate significant revenue in order to achieve profitability.

We operate in one business segment.

Debt Refinancing

On May 10, 2017, the Company and its domestic subsidiaries, as co-borrowers, entered into a Loan and Security Agreement, or the Innovatus Loan Agreement with Innovatus Life Sciences Lending Fund I, LP, as Lender and Collateral Agent, or the Lender.  Under the Innovatus Loan Agreement, the Lender has agreed to make certain term loans in the aggregate principal amount of up to $17,000,000. Funding of the first $14,000,000 tranche occurred on May 10, 2017. The Company will be eligible to draw on the second tranche of $3,000,000 upon achievement of certain milestones. So long as the Company meets each Interest-Only Milestone (as defined below), the Company is entitled to make interest-only payments for up to twenty-four (24) months. At the end of the interest-only period, the Company will be required to repay the term loans over a two-year period, based on a twenty-four (24) month amortization schedule, with a final maturity date occurring on the fourth anniversary of the initial funding date.  However, the interest-only period will end if the Company fails to meet any Interest-Only Milestone. Commencing on the first day of the month following such failure to achieve an Interest-Only Milestone, the Company will be required to repay the term loans over a two year period, based on a twenty-four (24) month amortization schedule.  The Interest-Only Milestones require the Company to (i) achieve certain twelve month revenue targets, measured quarterly, commencing with quarter ending March 31, 2018, (ii) meet a minimum capital raising threshold through the sale and issuance of equity securities during the period from April 10, 2017 through May 31, 2018 and (iii) obtain clearance for commercialization of the Senhance System by the U.S. Food and Drug Administration, or the Senhance Clearance, by May 30, 2018.  Each such milestone is referred to as an Interest-Only Milestone. In connection with its entrance into the Innovatus Loan Agreement, the Company repaid its existing credit facility with Silicon Valley Bank and Oxford Finance LLC under the SVB Loan Agreement.

The term loans bear interest at a fixed rate equal to 11% per annum, of which 2.5% can be paid in-kind and added to the outstanding principal amount of the term loans until the earlier of (i) the first anniversary following the funding date and (ii) the Company’s failure to achieve an Interest-Only Milestone.  The Company will be required to repay the term loans if they are accelerated following an event of default.  In addition, the Company is permitted to prepay the term loans in full at any time upon five (5) business days’ written notice to the Lender.  Upon the earliest to occur of the maturity date, acceleration of the term loan, or prepayment of the term loan, the Company is required to make a final payment equal to the total term loan commitment multiplied by four percent (4%); provided, however, that in the event the Company refinances its obligations with the Lender after Senhance Clearance, no final fee or prepayment fee described below will be due; and provided, further, that if the Company elects to refinance its obligations prior to the funding of the second tranche, the final fee with respect to the second tranche shall be paid in full on the date of such refinancing. Any prepayment of the term loans in full, whether mandatory or voluntary, must include (i) the final fee, (ii) interest at the default rate (which is the rate otherwise applicable plus five percent (5%)) with respect to any amounts past due, (iii) the Lender’s expenses and all other obligations that are due and payable to the Lender and (iv) a prepayment fee of three percent (3%) if the term loan is paid in full on or before the first anniversary of the effective date, two percent (2%) if paid off after the first anniversary but on or before the second anniversary of the effective date and one percent (1%) if paid off after the second anniversary but on or before the third anniversary of the effective date.

In connection with the funding, the Company paid a facility fee of $170,000 on the date of funding of the first tranche.  In addition, the Company issued warrants to the Lender to purchase shares of the Company’s common stock.  Additional warrants will be issued on the funding date of each subsequent tranche and will expire five (5) years from such issue date. The warrants issued in connection with funding of the first tranche entitle the Lender to purchase up to 1,244,746 shares of the Company’s common stock at an exercise price of $1.00 per share.

The Company’s obligations under the Innovatus Loan Agreement are secured by a security interest in all of the assets of the Company and its current and future domestic and material foreign subsidiaries, including a security interest in the intellectual property.  The Innovatus Loan Agreement contains customary representations and covenants that, subject to exceptions, restrict the Company’s ability to do the following things: declare dividends or redeem or repurchase equity interests; incur additional liens; make loans and investments; incur additional indebtedness; engage in mergers, acquisitions, and asset sales; transact with affiliates; undergo a change in control; add or change business locations; and engage in businesses that are not related to its existing business. Under the terms of the Innovatus Loan Agreement, the Company is required to maintain minimum unrestricted cash in an amount equal to (x) six million dollars ($6,000,000) at all times prior to Senhance Clearance; and (y) at all times thereafter, the lesser of (i) $6,000,000, (ii) the Company’s trailing three (3) months’ cash used to fund operating activities, as determined as of the most recent month end and (iii) the then outstanding principal amount of the term loans, together with accrued but unpaid interest.

Public Offering of Units

On April 28, 2017, we entered into an underwriting agreement with Stifel, Nicolaus & Company, Incorporated, or the Underwriter, relating to an underwritten public offering of an aggregate of 24,900,000 Units, each consisting of one share of the Company’s Common Stock, a Series A Warrant to purchase one share of Common Stock and a Series B Warrant to purchase 0.75 shares of Common Stock at an offering price to the public of $1.00 per Unit. Certain of the Company’s officers, directors and existing stockholders purchased approximately $2.5 million of Units in the public offering. The closing of the public offering occurred on May 3, 2017.

Each Series A Warrant had an initial exercise price of $1.00 per share and was able to be exercised at any time beginning on the date of issuance, and from time to time thereafter, through and including the first anniversary of the issuance date, unless terminated earlier as provided in the Series A Warrant. Receipt of 510(k) clearance for the Senhance System on October 13, 2017, triggered the acceleration of the expiration date of the Series A Warrants to October 31, 2017.  As of December 31, 2017, all of the Series A Warrants had been exercised.

Each Series B Warrant has an initial exercise price of $1.00 per share and may be exercised at any time beginning on the date of issuance and from time to time thereafter through and including the fifth anniversary of the issuance date, or by May 3, 2022. As of December 31, 2017, Series B Warrants representing approximately 8.9 million shares had been exercised.

The exercise prices and the number of shares issuable upon exercise of the outstanding Series B Warrants are subject to adjustment upon the occurrence of certain events, including, but not limited to, stock splits or dividends, business combinations, sale of assets, similar recapitalization transactions, or other similar transactions. The Series B Warrants are subject to adjustment in the event that the Company issues or is deemed to issue shares of common stock for less than the then applicable exercise price of the Series B Warrants. The exercisability of the Series B Warrants may be limited if, upon exercise, the holder or any of its affiliates would beneficially own more than 4.99% of our common stock. If, at any time Series B Warrants are outstanding, any fundamental transaction occurs, as described in the Series B Warrants and generally including any consolidation or merger into another corporation, the consummation of a transaction whereby another entity acquires more than 50% of the Company’s outstanding voting stock, or the sale of all or substantially all of its assets, the successor entity must assume in writing all of the obligations to the Series B Warrant holders. Additionally, in the event of a fundamental transaction, each Series B Warrant holder will have the right to require the Company, or its successor, to repurchase the Series B Warrants for an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of such Series B Warrants.

The underwriting agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended, other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the underwriting agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties.

The net proceeds to the Company from the offering were approximately $23.2 million, prior to any exercise of the Series A Warrants or Series B Warrants, after deducting underwriting discounts and commissions and estimated offering expenses paid by the Company. The net proceeds to the Company from the exercise of all of the Series A Warrants and the Series B Warrants exercised prior to December 31, 2017 were approximately $33.6 million.

The Units were issued pursuant to a prospectus supplement dated April 28, 2017 and an accompanying base prospectus dated June 22, 2016 that form a part of the registration statement on Form S-3 that the Company filed with the SEC on November 7, 2014 and was declared effective on December 19, 2014 (File No. 333-199998), and post-effectively amended pursuant to Post-Effective Amendment No. 1 on Form S-3, as filed with the SEC on March 8, 2016 and declared effective on June 22, 2016 and a related registration statement filed pursuant to Rule 462(b) promulgated under the Securities Act of 1933.

On December 15, 2017, we filed a registration statement on Form S-3 (File No. 333-222103) to register shares of common stock underlying outstanding Series B Warrants previously issued as part of the Company’s May 3, 2017 public offering.  The new registration statement replaced the registration statement on Form S-3 that expired on December 19, 2017 with respect to these securities.  On January 26, 2018, we filed an Amendment No. 1 to such registration statement on Form S-3 to update the information, in the registration statement.  The registration statement covers up to 9,579,884 shares of common stock underlying the outstanding Series B Warrants.  This registration statement on Form S-3 was declared effective on January 29, 2018.

Lincoln Park Purchase Agreement

On December 16, 2016, we entered into a purchase agreement, or the LPC Purchase Agreement, with Lincoln Park Capital Fund, LLC, an Illinois limited liability company, or Lincoln Park, pursuant to which we had the right to sell to Lincoln Park up to an aggregate of $25,000,000 in shares of our common stock, subject to certain limitations and conditions set forth in the LPC Purchase Agreement.  Effective April 27, 2017, we terminated the LPC Purchase Agreement. The LPC Purchase Agreement provided us with an election to terminate the Purchase Agreement for any reason or for no reason by delivering a notice to Lincoln Park, and we did not incur any early termination penalties in connection with the termination of the LPC Purchase Agreement. Prior to termination, we sold shares of our common stock to Lincoln Park under the LPC Purchase Agreement for gross proceeds of approximately $5.7 million.

At-the-Market Offerings

On February 9, 2016, we entered into a Controlled Equity Offering SM Sales Agreement, or the “2016 Sales Agreement, with Cantor Fitzgerald & Co., or Cantor, under which we could offer and sell, through Cantor, up to approximately $43.6 million in shares of common stock in an at-the market offering, or the 2016 ATM Offering. The 2016 Sales Agreement was terminated, effective September 10, 2017. On February 20, 2015, we had entered into a Controlled Equity Offering SM Sales Agreement, or the 2015 Sales Agreement, with Cantor, as sales agent, pursuant to which we offered and sold, through Cantor, $25.0 million in shares of common stock in an at-the-market offering from February 2015 through February 2016, or the 2015 ATM Offering. All sales of shares under these offerings were made pursuant to an effective shelf registration statement on Form S-3 filed with the SEC. We paid Cantor a commission of approximately 3% of the aggregate gross proceeds received from all sales of common stock under the 2015 Sales Agreement and the 2016 Sales Agreement.

On August 31, 2017, we entered into an At-the-Market Equity Offering Sales Agreement, or the 2017 Sales Agreement, with Stifel, Nicolaus & Company, Incorporated, or Stifel, under which we could offer and sell, through Stifel, up to approximately $50.0 million in shares of common stock in an at-the-market offering, or the 2017 ATM Offering.

We paid Stifel a commission of approximately 3% of the aggregate gross proceeds received from all sales of common stock under the 2017 Sales Agreement. As of October 31, 2017, the 2017 ATM Offering was completed.

The following table summarizes the total sales under the 2015 Sales Agreement, 2016 Sales Agreement and 2017 Sales Agreement for the periods indicated (in thousands, except per share amounts):

Senhance Acquisition and Related Transactions

Membership Interest Purchase Agreement and Amendment

On September 21, 2015, the Company announced that it had entered into a Membership Interest Purchase Agreement, dated September 18, 2015 with Sofar S.p.A., as the Seller, Vulcanos S.r.l., as the acquired company, and TransEnterix International, Inc., a wholly owned subsidiary of the Company as the Buyer. The closing of the transactions contemplated by the Purchase Agreement occurred on September 21, 2015.  The Buyer acquired all of the membership interests of the acquired company from the Seller, and changed the name of the acquired company to TransEnterix Italia S.r.l. On the closing date, pursuant to the Purchase Agreement, the Company completed the strategic acquisition from Sofar S.p.A. of all of the assets, employees and contracts related to the advanced robotic system for minimally invasive laparoscopic surgery now known as the Senhance System, or the Senhance Acquisition.

29

Under the terms of the Purchase Agreement, the consideration consisted of the issuance of 15,543,413 shares of the Company’s common stock, or the Securities Consideration, and approximately $25,000,000 U.S. Dollars and €27,500,000 Euro in cash consideration, or the Cash Consideration. The Securities Consideration was issued in full at closing of the acquisition; the Cash Consideration was or will be paid in four tranches, with US $25,000,000 paid at closing and the remaining Cash Consideration of €27,500,000 to be paid in three additional tranches based on achievement of negotiated milestones. On December 30, 2016, the Company and Sofar entered into an Amendment to the Purchase Agreement to restructure the terms of the second tranche of the Cash Consideration. Under the Amendment, the second tranche was restructured to reduce the contingent cash consideration by €5.0 million in exchange for the issuance of 3,722,685 shares of the Company’s common stock with an aggregate fair market value of €5.0 million, which were issued on January 4, 2017. The price per share was $1.404 and was calculated based on the average of the closing prices of the Company’s common stock on ten consecutive trading days ending one day before the execution of the Amendment. 

The issuance of the initial Securities Consideration was effected as a private placement of securities under Section 4(a)(2) of the Securities Act, and Regulation D promulgated thereunder.  The issuance of the additional shares in January 2017 was made under an existing shelf registration statement on Form S-3.

As of December 31, 2017, the Company has paid all Cash Consideration due under the second tranche and €1.8 million due under the fourth tranche.

The Purchase Agreement contains customary representations and warranties of the parties and the parties have customary indemnification obligations, which are subject to certain limitations described further in the Purchase Agreement.

Registration Rights and Lock-Up Agreements

In connection with the Senhance Acquisition, we also entered into a Registration Rights Agreement, dated as of September 21, 2015, with the Seller, pursuant to which we agreed to register the Securities Consideration shares for resale following the end of the lock-up periods described below. The resale Registration Statement has been filed and is effective.

In connection with the Senhance Acquisition, Sofar entered into a Lock-Up Agreement with us pursuant to which Sofar agreed, subject to certain exceptions, not to sell, transfer or otherwise convey any of the Securities Consideration over a two-year period following the Closing Date. As of September 21, 2017, all of the Securities Consideration was released from the lock-up restrictions and is eligible to be resold under the effective resale registration statement.  

2015 Public Offering

On June 11, 2015, we sold 16,666,667 shares of common stock at a public offering price of $3.00 per share for aggregate gross proceeds of $50.0 million in an underwritten firm commitment public offering. We granted the underwriters an option, exercisable for 30 days, to purchase up to an additional 2,500,000 shares of common stock to cover over-allotments. The common stock was offered and sold pursuant to our shelf registration statement on Form S-3 (File No. 333-199998) registering an aggregate of $100.0 million of our designated securities. The closing of the public offering occurred on June 17, 2015. On July 10, 2015, the underwriters exercised a portion of their over-allotment option to acquire an additional 2,075,000 shares at the public offering price of $3.00 per share for aggregate additional gross proceeds of $6.2 million. The purchase of the over-allotment shares closed on July 15, 2015. Total proceeds were $52.2 million, net of issuance costs of $4.0 million.

Results of Operations

Our results of operations include the operations of TransEnterix Italia from the Senhance Acquisition date of September 21, 2015 forward.

Revenue

In 2017, our revenue consisted of product and service revenue resulting from a total of four Senhance Systems: Europe (two), Asia (one) and the United States (one), and related instruments, accessories and services. In 2016, our revenue consisted of product and service revenue resulting from the sale in Europe of a Senhance System, instruments and accessories, and related services. We recognize revenue when persuasive evidence that an arrangement exists, delivery has occurred or service has been rendered, the price is fixed or determinable, and collectability is reasonably assured. Amounts billed in excess of the associated revenue recognized are deferred.

30

We expect to experience some unevenness in the number and trend, and average selling price, of units sold on a quarterly basis given the early stage of commercialization of our products.

Product and service revenue for the year ended December 31, 2017 increased to $7.1 million compared to $1.5 million for the year ended December 31, 2016. The $5.6 million increase was the result of the revenue recognized on the sale of four Senhance Systems, net of deferred revenue.

Product and service revenue for the year ended December 31, 2016 increased to $1.5 million compared to $0 for the year ended December 31, 2015. The $1.5 million increase was the result of the revenue recognized on the sale of one Senhance System, net of deferred revenue, during the third quarter of 2016.

Cost of Revenue

Cost of revenues consists primarily of costs related to contract manufacturing, materials, and manufacturing overhead. We expense all inventory provisions as cost of revenues. The manufacturing overhead costs include the cost of quality assurance, material procurement, inventory control, facilities, equipment depreciation and operations supervision and management. We expect overhead costs as a percentage of revenues to become less significant as our production volume increases. We expect cost of revenues to increase in absolute dollars to the extent our revenues grow and as we continue to invest in our operational infrastructure to support anticipated growth.

Cost of revenue for the year ended December 31, 2017 increased to $6.7 million as compared to $1.1 million for the year ended December 31, 2016. This increase over the prior year period was the result of increased sales and costs for manufacturing overhead and field service.

Cost of revenue for the year ended December 31, 2016 increased to $1.1 million as compared to $0 for the year ended December 31, 2015. This increase over the prior year period was the result of the costs recognized in connection with the sale of one Senhance System during the third quarter of 2016. The $1.1 million cost of revenue primarily represents the fair value of the Senhance System determined using the acquisition method of accounting at the Senhance Acquisition date.

Research and Development

Research and development, or R&D expenses primarily consist of engineering, product development and regulatory expenses incurred in the design, development, testing and enhancement of our products and legal services associated with our efforts to obtain and maintain broad protection for the intellectual property related to our products. In future periods, we expect R&D expenses to remain consistent or be modestly lower as we continue to transition our investments into commercial activities. R&D expenses are expensed as incurred.

R&D expenses for the year ended December 31, 2017 decreased 25% to $22.0 million as compared to $29.3 million for the year ended December 31, 2016. The $7.3 million decrease resulted primarily from decreased personnel costs of $4.0 million, decreased supplies expense of $1.9 million, decreased contract engineering services, consulting and other outside services of $2.0 million and decreased other costs of $0.1 million, offset by increased stock compensation costs of $0.7 million

R&D expenses for the year ended December 31, 2016 decreased 1% to $29.3 million as compared to $29.7 million for the year ended December 31, 2015. The $0.4 million decrease resulted primarily from decreased supplies expense of $3.7 million and decreased contract engineering services, consulting and other outside services of $3.6 million, offset by increased preclinical lab expense of $3.8 million, increased facility costs of $0.9 million, increased stock compensation costs of $0.8 million, increased travel related expenses of $0.5 million, increased other costs of $0.6 million and increased personnel related costs of $0.3 million.

Sales and Marketing

Sales and marketing expenses include costs for sales and marketing personnel, travel, demonstration product, market development, physician training, tradeshows, marketing clinical studies and consulting expenses. We expect sales and marketing expenses to increase significantly in 2018 in support of our Senhance System commercialization.

Sales and marketing expenses for the year ended December 31, 2017 increased 90% to $17.5 million compared to $9.2 million for the year ended December 31, 2016. The $8.3 million increase was primarily related to increased personnel related costs of $3.0 million, increased consulting and outside service costs of $1.8 million, increased depreciation expense $1.0 million, increased travel related expenses of $0.8 million, increased stock compensation costs of $0.5 million, increased demonstration product costs of $0.5 million, increased tradeshow costs of $0.4 million and increased other costs of $0.3 million, as we increased our U.S. sales and marketing team following receipt of 510(k) clearance for the Senhance System.

31

Sales and marketing expenses for the year ended December 31, 2016 increased 217% to $9.2 million compared to $2.9 million for the year ended December 31, 2015. The $6.3 million increase was primarily related to increased personnel related costs of $2.6 million, increased travel related expenses of $1.0 million, increased consulting costs of $0.9 million, increased tradeshow costs of $0.5 million, increased stock compensation costs of $0.5 million, increased other costs of $0.6 million and increased depreciation expense of $0.2 million.

General and Administrative

General and administrative expenses consist of personnel costs related to the executive, finance and human resource functions, as well as professional service fees, legal fees, accounting fees, insurance costs, and general corporate expenses. In future periods, we expect general and administrative expenses to increase to support our sales, marketing, and research and development efforts.

General and administrative expenses for the year ended December 31, 2017 increased 14% to $12.3 million compared to $10.8 million for the year ended December 31, 2016. The $1.5 million increase was primarily due to increased stock compensation costs of $0.7 million, increased personnel costs of $0.5 million and increased other costs of $1.0 million offset by decreased legal, accounting, and investor relation fees and other public company costs of $0.7 million.

General and administrative expenses for the year ended December 31, 2016 increased 38% to $10.8 million compared to $7.8 million for the year ended December 31, 2015. The $3.0 million increase was primarily due to increased legal, accounting, and investor relation fees and other public company costs of $1.8 million, increased stock compensation costs of $0.5 million, increased personnel costs of $0.4 million, and increased other costs of $0.3 million.

Amortization of Intangible Assets

Amortization of intangible assets for the year ended December 31, 2017 increased to $7.9 million compared to $7.0 million for the year ended December 31, 2016. The $0.9 million increase was primarily the result of amortization of developed technology related to the acquisition of the Senhance System on September 21, 2015 and the amortization of in-process research and development transferred to intellectual property in October 2017.

Amortization of intangible assets for the year ended December 31, 2016 increased to $7.0 million compared to $2.2 million for the year ended December 31, 2015. The $4.8 million increase was primarily the result of amortization of developed technology related to the acquisition of the Senhance System on September 21, 2015.

Change in Fair Value of Contingent Consideration

The change in fair value of contingent consideration in connection with the Senhance Acquisition was $2.0 million for the year ended December 31, 2017 primarily related to the change in expected timelines for the achievement of milestones, the effect of the passage of time on the fair value measurement and the impact of foreign currency exchange rates.  

The change in fair value of contingent consideration in connection with the Senhance Acquisition was $0.5 million for the year ended December 31, 2016 primarily related to the Amendment to the Purchase Agreement for the second tranche, the change in expected timelines for the achievement of milestones, the effect of the passage of time on the fair value measurement and the impact of foreign currency exchange rates.  

Issuance costs for Warrants

Issuance costs of $0.6 million were allocated to the Series A Warrants and Series B Warrants issued in April 2017.

Inventory write-down related to restructuring

On April 19, 2016, the FDA notified the Company that the SurgiBot System did not meet the criteria for substantial equivalence based on the data submitted in the 510(k) submission. As a result, we reprioritized our near-term regulatory efforts to the 510(k) submission for the Senhance System. Consequently, in May 2016, the Company implemented a restructuring plan.  Under this plan, we recorded a $2.6 million write-down of inventory related to the SurgiBot System.

32

Restructuring and other charges

Under the restructuring plan executed in May 2016, we recorded $3.1 million in restructuring and other charges. The restructuring charges included: (i) $0.5 million to be paid in cash, of which $0.4 million related to employee severance costs and $0.1 million related to cancellation of certain contracts; and (ii) $2.6 million for other non-cash charges, of which $1.0 million related to the write-off of long-lived assets for the abandonment of certain equipment and tooling and $1.6 million related to the write-off of intellectual property for certain patents.

Goodwill impairment

The Company performs an annual impairment test of goodwill at December 31, or more frequently if events or changes in circumstances indicate that the carrying value of our one reporting unit may not be recoverable. During the second quarter of 2016, we were notified by the FDA that the SurgiBot System did not meet the criteria for substantial equivalency, negatively impacting our market capitalization, and warranting an interim two-step quantitative impairment test.  Based on the impairment test, we recorded goodwill impairment of $61.8 million during the second quarter of 2016.  No charge for goodwill impairment was required as of December 31, 2017.

Acquisition Related Costs

Acquisition related costs consist primarily of legal, accounting and other professional fees related to the Senhance Acquisition. We incurred $4.2 million of acquisition-related expenses for the year ended December 31, 2015.

Change in Fair Value of Warrant Liabilities

The change in fair value of Series A Warrants and Series B Warrants issued in April 2017 was $83.7 million for the year ended December 31, 2017. The increase was primarily the result of our increased stock price at the time the warrants were exercised and increased stock price for the remaining outstanding warrants at December 31, 2017.

Interest Expense, Net

Interest expense for the year ended December 31, 2017 increased to $2.1 million compared to $1.9 million for the year ended December 31, 2016. The $0.2 million increase was primarily related to the increase in interest rate on refinanced notes payable.

Interest expense for the year ended December 31, 2016 increased to $1.9 million compared to $1.6 million for the year ended December 31, 2015. The $0.3 million increase was primarily related to the increase in notes payable of approximately $10.0 million in August 2015.

Income Tax Benefit

Income tax benefit consists primarily of taxes related to the amortization of purchase accounting intangibles in connection with the Italian taxing jurisdiction for TransEnterix Italia as a result of the acquisition of the Senhance System. We recognized $3.3 million, $5.5 million and $1.0 million of income tax benefit for the year ended December 31, 2017, 2016 and 2015, respectively.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception we have incurred significant losses and, as of December 31, 2017, we had an accumulated deficit of $447.6 million. We have not yet achieved profitability and we cannot assure investors that we will achieve profitability with our existing capital resources. As of December 31, 2017, the Company's cash and restricted cash balance was approximately $97.6 million. We believe that our existing cash and cash equivalents, together with cash received from sales of our products, will be sufficient to fund operations through at least the next 12 months. We expect to continue to fund sales and marketing, research and development and general and administrative expenses at similar to current or higher levels and, as a result, we will need to generate significant revenues to achieve profitability. Our principal sources of cash to date have been proceeds from public offerings of common stock, private placements of common and preferred stock, incurrence of debt and the sale of equity securities held as investments.

33

We currently have one effective shelf registration statement on file with the SEC, which registers up to $150.0 million of debt securities, common stock, preferred stock, or warrants, or any combination thereof for future financing transactions.  The shelf registration statement was declared effective by the SEC on May 19, 2017. We have raised $50.0 million in gross proceeds and approximately $48.5 in net proceeds under such shelf registration statement through the sale of all the shares available under the 2017 ATM Offering. As of December 31, 2017, we had $100.0 million available for future financings under such shelf registration statement.  

At December 31, 2017, we had cash and cash equivalents, excluding restricted cash, of approximately $91.2 million.

Consolidated Cash Flow Data

Operating Activities

For the year ended December 31, 2017, cash used in operating activities of $39.8 million consisted of net loss of $144.8 million offset by cash provided by working capital of $3.4 million and non-cash items of $101.6 million. The non-cash items primarily consisted of $83.7 million change in fair value of warrant liabilities, $7.1 million of stock-based compensation expense, $2.5 million of depreciation, $7.9 million of amortization, and $2.0 million change in fair value of contingent consideration, offset by $3.3 million deferred income tax benefit. The increase in cash from changes in working capital included $2.1 million increase in accrued expenses, $7.5 million increase for cash received for the sale of the SurgiBot assets and $1.1 million increase for deferred revenue, offset by $3.0 million increase in inventories, $0.5 million decrease in accounts payable, $3.3 million increase in other current and long term assets and $0.4 million increase in accounts receivable.

For the year ended December 31, 2016, cash used in operating activities of $52.4 million consisted of net loss of $120.0 million and cash used for working capital of $8.5 million, offset by non-cash items of $76.1 million. The non-cash items primarily consisted of $61.8 million goodwill impairment, $2.6 million inventory write-down related to restructuring, $2.6 million non-cash restructuring and other charges, $5.0 million of stock-based compensation expense, $1.9 million of depreciation, $7.1 million of amortization, and $0.5 million change in fair value of contingent consideration, offset by $5.6 million deferred income tax benefit. The decrease in cash from changes in working capital included $6.6 million increase in inventories, $0.4 million decrease in accounts payable, $1.5 million increase in other current and long term assets and $1.0 million increase in accounts receivable, offset by  $1.1 million increase in accrued expenses.

For the year ended December 31, 2015, cash used in operating activities of $38.8 million consisted of net loss of $46.9 million, offset by non-cash items of $5.5 million and cash provided by working capital of $2.6 million. The non-cash items primarily consisted of $3.3 million of stock-based compensation expense, $1.3 million of depreciation, and $2.3 million of amortization, offset by $1.0 million deferred income tax benefit and $0.4 million change in fair value of contingent consideration. The increase in cash from changes in working capital included $1.9 million increase in inventories and $2.0 million increase in other current and long term assets. These amounts were partially offset by $1.1 million increase in accounts payable, $5.4 million increase in accrued expenses and $0.1 million decrease in accounts receivable.

Investing Activities

For the year ended December 31, 2017, net cash used in investing activities was $2.0 million. This amount reflected the purchases of property and equipment and intellectual property.

For the year ended December 31, 2016, net cash used in investing activities was $1.4 million. This amount reflected the purchases of property and equipment.

34

For the year ended December 31, 2015, net cash used in investing activities was $26.2 million. This amount reflected the $25.0 million payment for the Senhance Acquisition and $1.2 million paid for the purchases of property and equipment.

Financing Activities

For the year ended December 31, 2017, net cash provided by financing activities was $104.4 million. This amount was primarily related to $77.6 million in proceeds from the issuance of common stock and warrants, net of issuance costs, $13.0 million in proceeds from the issuance of debt and $34.5 million proceeds from the exercise of warrants, partially offset by $13.3 million in payments of debt and $7.2 million in payments of contingent consideration.

For the year ended December 31, 2016, net cash provided by financing activities was $49.9 million. This amount was primarily related to $58.0 million in proceeds from the issuance of common stock, net of issuance costs, partially offset by $6.9 million in payments of debt and $1.2 million in payments of contingent consideration.

For the year ended December 31, 2015, net cash provided by financing activities was $68.4 million. This amount was primarily related $58.3 million in proceeds from the issuance of common stock, net of issuance costs, and $9.9 million proceeds from the issuance of debt, and $0.2 million proceeds from the issuance of stock options and warrants.

Operating Capital and Capital Expenditure Requirements

We believe that our existing cash and cash equivalents, together with cash received from sales of our products, will be sufficient to meet our anticipated cash needs through at least the next 12 months. We intend to spend substantial amounts on commercial activities, on research and development activities, including product development, regulatory and compliance, clinical studies in support of our future product offerings, the enhancement and protection of our intellectual property, on notes payable payments as they come due, and on contingent consideration payments in connection with the acquisition of the Senhance System. We will need to obtain additional financing to pursue our business strategy, to respond to new competitive pressures or to take advantage of opportunities that may arise. To meet our capital needs, we are considering multiple alternatives, including, but not limited to, additional equity financings, debt financings, strategic collaborations and other funding transactions. There can be no assurance that we will be able to complete any such transaction on acceptable terms or otherwise. If we are unable to obtain the necessary capital, we will need to pursue a plan to license or sell our assets, seek to be acquired by another entity, cease operations and/or seek bankruptcy protection.

Cash and cash equivalents held by our foreign subsidiaries totaled $1.8 million at December 31, 2017, including restricted cash. We do not intend or currently foresee a need to repatriate cash and cash equivalents held by our foreign subsidiary. If these funds are needed in the U.S., we believe that the potential U.S. tax impact to repatriate these funds would be immaterial.

Innovatus Loan Agreement

On May 10, 2017, the Company and its domestic subsidiaries, as co-borrowers, entered into the Innovatus Loan Agreement with Innovatus Life Sciences Lending Fund I, LP, as Lender and Collateral Agent.  Please see the description of the Innovatus Loan Agreement above in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations‑Debt Refinancing.  

SVB Loan Agreement

In connection with its entrance into the Innovatus Loan Agreement on May 10, 2017, the Company repaid its existing credit facility with Silicon Valley Bank and Oxford Finance LLC, or the Prior Lenders, under the SVB Loan Agreement, , initially entered into in January 2012, as subsequently amended or amended and restated, or, collectively, the SVB Loan Agreement. A number of the amendments related to the Senhance Acquisition or the growth of our business in non-U.S. jurisdictions. Under the SVB Loan Agreement, our current borrowing capacity was $20.0 million, all of which was borrowed under term loans. We had periods of interest-only payments during the SVB Loan Agreement, and had been making principal payments since January 2016. The maturity date of the term loans was July 1, 2018.

In connection with the entry into the Innovatus Loan Agreement, we were obligated to pay final payment and facility fees under the SVB Loan Agreement. The final payment fee obligation was $1.3 million.

35

Contractual Obligations and Commercial Commitments

The following table summarizes our contractual obligations as of December 31, 2017 (in millions):

Long-term debt obligations include future payments under the Innovatus Loan Agreement.

Operating lease amounts include future minimum lease payments under all our non-cancelable operating leases with an initial term in excess of one year. We rent office space in North Carolina under an operating lease which expires in 2018, with options to extend the lease through 2021. We also rent space for a warehouse facility in North Carolina which expired in January 2018. In Italy, we rent space for research and development and demonstration facilities under an operating lease which expires in 2022. This table does not include obligations for any lease extensions.

License, supply and third party vendor agreements include agreements assumed as part of the Senhance Acquisition and other third party vendor agreements.

Off-Balance Sheet Arrangements

As of December 31, 2017, we did not have any off-balance sheet arrangements.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations set forth above under the headings “Results of Operations” and “Liquidity and Capital Resources” have been prepared in accordance with U.S. GAAP and should be read in conjunction with our financial statements and notes thereto appearing in Item 8 of this Annual Report. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our critical accounting policies and estimates, including identifiable intangible assets and goodwill, in-process research and development, contingent consideration, warrant liabilities, stock-based compensation, inventory, and revenue recognition. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. A more detailed discussion on the application of these and other accounting policies can be found in Note 2 in the Notes to the Financial Statements set forth in our financial statements for the years ended December 31, 2017, 2016, and 2015 which are included as Item 8 of this Annual Report. Actual results may differ from these estimates under different assumptions and conditions.

While all accounting policies impact the financial statements, certain policies may be viewed as critical. Critical accounting policies are those that are both most important to the portrayal of financial condition and results of operations and that require management’s most subjective or complex judgments and estimates. Our management believes the policies that fall within this category are the policies on accounting for identifiable intangible assets and goodwill, in-process research and development, contingent consideration, warrants liabilities, stock-based compensation, inventory and revenue recognition.

Identifiable Intangible Assets and Goodwill

Identifiable intangible assets consist of purchased patent rights recorded at cost and developed technology acquired as part of a business acquisition recorded at estimated fair value. Intangible assets are amortized over 5 to 10 years. We periodically evaluate identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. 

36

Indefinite-lived intangible assets, such as goodwill, are not amortized. We test the carrying amounts of goodwill for recoverability on an annual basis or when events or changes in circumstances indicate evidence of potential impairment exists by performing either a qualitative evaluation or a two-step quantitative test. The qualitative evaluation is an assessment of factors, including industry, market and general economic conditions, market value, and future projections to determine whether it is more likely than not that the fair value of a reporting unit is less than it’s carrying amount, including goodwill. Prior to the adoption of Accounting Standards Update (“ASU”) 2017-14, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), as of the beginning of fiscal year 2017, in certain instances, we elected to bypass this qualitative assessment and perform a two-step quantitative test. The quantitative goodwill impairment test was performed using a two-step approach. In the first step, the fair value of the reporting unit was determined and compared to the reporting unit's carrying value, including goodwill. If the fair value of the reporting unit was less than its carrying value, the second step of the goodwill impairment test was performed to measure the amount of impairment, if any. In the second step, the fair value of the reporting unit was allocated to the assets and liabilities of the reporting unit as if it had been acquired in a business combination and the purchase price was equivalent to the fair value of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to its assets and liabilities was referred to as the implied fair value of goodwill. The implied fair value of the reporting unit's goodwill was then compared to the actual carrying value of goodwill. If the implied fair value of goodwill was less than the carrying value of goodwill, an impairment loss was recognized for the difference. ASU 2017-04 removes Step 2 of the goodwill impairment test.

During the second quarter of 2016, the FDA notified the Company that the SurgiBot System did not meet the criteria for substantial equivalency, negatively impacting the Company’s market capitalization, and warranting an interim two-step quantitative impairment test.  We determined the fair value of our reporting unit using a discounted cash flow analysis derived from our long-term plans.  The fair value of the reporting unit was corroborated using market prices for TransEnterix, Inc.  The inputs used to determine the fair values were classified as Level 3 in the fair value hierarchy. Based on the impairment test, we recorded goodwill impairment of $61.8 million during the second quarter of 2016.  We performed a qualitative assessment during the annual impairment review for fiscal 2016 as of December 31, 2016 and concluded that it is not more likely than not that the fair value of our single reporting unit was less than its carrying amount. Therefore, the two-step goodwill impairment test for the reporting unit was not necessary as of December 31, 2016.

During the second quarter of 2017, our stock price experienced a significant decline and as of June 30, 2017 we performed a Step 1 goodwill impairment test as of the second quarter.  Our analysis included utilizing our market capitalization with a control premium. To determine the appropriate control premium, we considered recent merger and acquisition transaction activity of comparable public healthcare equipment companies.  Based on this analysis, we determined a control premium range of approximately 19% to 46%, and selected the mid-range of approximately 32.5%.  After applying a 32.5% control premium, our market value exceeded our carrying value by 13%. Based on this analysis, we determined that no charge to goodwill for impairment was required during the second quarter of 2017. As of December 31, 2017, we elected to bypass the qualitative assessment and calculated the fair value of our reporting unit, which exceeded the carrying amount. Accordingly, no charge for goodwill impairment was required as of December 31, 2017.

A significant amount of judgment is involved in determining if an indicator of goodwill impairment has occurred. Such indicators may include, among others: a significant decline in expected future cash flows; a sustained, significant decline in the Company's stock price and market capitalization; a significant adverse change in legal factors or in the business climate; adverse assessment or action by a regulator; and unanticipated competition. Key assumptions used in the annual goodwill impairment test are highly judgmental and include: selection of comparable companies and amount of control premium. Any change in these indicators or key assumptions could have a significant negative impact on the Company's financial condition, impact the goodwill impairment analysis or cause the Company to perform a goodwill impairment analysis more frequently than once per year.

In-Process Research and Development

In-process research and development, or IPR&D, assets are considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. IPR&D assets represent the fair value assigned to technologies that we acquire, which at the time of acquisition have not reached technological feasibility and have no alternative future use. During the period that the assets are considered indefinite-lived, they are tested for impairment on an annual basis, or more frequently if we become aware of any events occurring or changes in circumstances that indicate that the fair value of the IPR&D assets are less than their carrying amounts. If and when development is complete, which generally occurs when we have regulatory approval and are able to commercialize products associated with the IPR&D assets, these assets are then deemed definite-lived and are amortized based on their estimated useful lives at that point in time. If development is terminated or abandoned, we may have a full or partial impairment charge related to the IPR&D assets, calculated as the excess of carrying value of the IPR&D assets over fair value.

37

Contingent Consideration

Contingent consideration is recorded as a liability and measured at fair value using a discounted cash flow model utilizing significant unobservable inputs including the probability of achieving each of the potential milestones and an estimated discount rate associated with the risks of the expected cash flows attributable to the various milestones. Significant increases or decreases in any of the probabilities of success or changes in expected timelines for achievement of any of these milestones would result in a significantly higher or lower fair value of these milestones, respectively, and commensurate changes to the associated liability. The fair value of the contingent consideration at each reporting date will be updated by reflecting the changes in fair value in our statements of operations and comprehensive loss.

Warrant Liabilities

For the Series A Warrants and Series B Warrants, the warrants are recorded as liabilities and are revalued at each reporting period. The change in fair value is recognized in the consolidated statements of operations and comprehensive loss. The selection of the appropriate valuation model and the inputs and assumptions that are required to determine the valuation requires significant judgment and requires management to make estimates and assumptions that affect the reported amount of the related liability and reported amounts of the change in fair value. Actual results could differ from those estimates, and changes in these estimates are recorded when known. As the warrant liability is required to be measured at fair value at each reporting date, it is reasonably possible that these estimates and assumptions could change in the near term.    

Stock-Based Compensation

We recognize as expense, the grant-date fair value of stock options and other stock based compensation issued to employees and non-employee directors over the requisite service periods, which are typically the vesting periods. We use the Black-Scholes-Merton model to estimate the fair value of our stock-based payments. The volatility assumption used in the Black-Scholes-Merton model is based on the calculated historical volatility based on an analysis of reported data for a peer group of companies as well as the Company’s historical volatility. The expected term of options granted by us has been determined based upon the simplified method, because we do not have sufficient historical information regarding our options to derive the expected term. Under this approach, the expected term is the mid-point between the weighted average of vesting period and the contractual term. The risk-free interest rate is based on U.S. Treasury rates whose term is consistent with the expected life of the stock options. We have not paid and do not anticipate paying cash dividends on our shares of common stock; therefore, the expected dividend yield is assumed to be zero. We estimate forfeitures based on our historical experience and adjust the estimated forfeiture rate based upon actual experience. We adopted ASU 2016-09, Compensation – Stock Compensation (Topic 718) – Improvements to Employee Share-Based Payment Accounting as of the beginning of fiscal year 2017 and did not elect to account for forfeitures when they occur, but will continue to estimate the number of awards that are expected to vest. The adoption of this ASU did not have a material impact on the consolidated financial statements.

Inventory

Inventory, which includes material, labor and overhead costs, is stated at the lower of cost, determined on a first-in, first-out basis, or net realizable value. We record reserves, when necessary, to reduce the carrying value of inventory to its net realizable value. At the point of loss recognition, a new, lower-cost basis for that inventory is established, and any subsequent improvements in facts and circumstances do not result in the restoration or increase in that newly established cost basis.

Revenue Recognition

Our revenue consists of product revenue resulting from the sales of systems, instruments and accessories, and service revenue. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or service has been rendered, the price is fixed or determinable, and collectability is reasonably assured. Revenue is presented net of taxes collected from customers that are remitted to government authorities. We generally recognize revenue at the following points in time:

38

Our system sale arrangements contain multiple elements including a system(s), instruments, accessories, and system service. We generally deliver all of the elements, other than service, within days of entering into the system sale arrangement. Each of these elements is a separate unit of accounting. System instruments, accessories and service are also sold on a stand-alone basis.

For multiple-element arrangements, revenue is allocated to each unit of accounting based on their relative selling prices. Relative selling prices are based first on vendor specific objective evidence of fair value (“VSOE”), then on third-party evidence of selling price (“TPE”) when VSOE does not exist, and then on management's best estimate of the selling price (“BESP”) when VSOE and TPE do not exist.

Our system sale arrangements generally include a one-year period of free service, and the right for the customer to purchase service annually thereafter. The revenue allocated to the free service period is deferred and recognized ratably over the free service period. Deferred revenue was primarily comprised of deferred revenue related to service contracts for the periods presented.

Because we have neither VSOE nor TPE for our systems, the allocation of revenue is based on BESP for the systems sold. The objective of BESP is to determine the price at which we would transact a sale, had the product been sold on a stand-alone basis. We determine BESP for our systems by considering multiple factors, including, but not limited to, features and functionality of the system, geographies, type of customer, and market conditions. We regularly review BESP and maintain internal controls over establishing and updating these estimates.

Recent Accounting Pronouncements

See “Note 2. Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” of this Annual Report for a full description of recent accounting pronouncements including the respective expected dates of adoption and effects on our Consolidated Balance Sheets and Consolidated Statements of Operations and Comprehensive Loss.

General

We have limited exposure to market risks from instruments that may impact the Balance Sheets, Statements of Operations and Comprehensive Loss, and Statements of Cash Flows. Such exposure is due primarily to changing interest rates and foreign currency exchange rates.

Interest Rates

The primary objective for our investment activities is to preserve principal while maximizing yields without significantly increasing risk. This is accomplished by investing excess cash in money market funds and Treasury securities. As of December 31, 2017, approximately 100% of the investment portfolio was in cash equivalents with very short term maturities and therefore not subject to any significant interest rate fluctuations.

Foreign Currency Exchange Rate Risk

We conduct operations in several different countries, including the U.S. and throughout Europe, and portions of our revenues, expenses, assets and liabilities are denominated in U.S. dollars, Euros or other currencies. Since our consolidated financial statements are presented in U.S. dollars, we must translate revenues, income and expenses, as well as assets and liabilities, into U.S. dollars at exchange rates in effect during or at the end of each reporting period. We have not historically hedged our exposure to foreign currency fluctuations.  Accordingly, increases or decreases in the value of the U.S. dollar against the Euro and other currencies could materially affect our net operating revenues, operating income and the value of balance sheet items denominated in foreign currencies.

During the year ended December 31, 2017, 82% of our revenue and approximately 39% of our expenses were denominated in currencies other than the U.S. dollar, most notably the Euro. Based on actual results over the past year, a hypothetical 10% increase or decrease in the U.S. dollar against the Euro would have increased or decreased revenue by approximately $0.6 million and operating expenses by approximately $2.4 million.

Opinion on Internal Control over Financial Reporting

We have audited TransEnterix, Inc.’s (the “Company’s”) internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO criteria”). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets of the Company and subsidiaries as of December 31, 2017 and 2016, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2017, and the related notes and our report dated March 8, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Item 9A, “Management’s Report on Internal Control over Financial Reporting”. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit of internal control over financial reporting in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
