1. Organization and Capitalization

TransEnterix, Inc. (the “Company”) is a medical device company that is pioneering the use of robotics to improve minimally invasive surgery by addressing the clinical challenges associated with current laparoscopic and robotic options. The Company is focused on the commercialization of its Senhance™ Surgical Robotic System  (the “Senhance System”), a multi-port robotic system that brings the advantages of robotic surgery to patients while enabling surgeons with innovative technology such as haptic feedback and eye sensing camera control. The Company also developed the SurgiBot™ System, a single-port, robotically enhanced laparoscopic surgical platform. 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 Section 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. The SurgiBot System is not available for sale in any market.

The Senhance System is a multi-port robotic surgery system which allows multiple arms to control robotic 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 features three-dimensional high definition (“3DHD”) vision technology. The Senhance System also offers responsible economics to hospitals by offering robotic technology with reusable instruments with minimal additional costs per surgery.

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. In May 2016, the Company implemented a restructuring plan. See Note 14 to the consolidated financial statements for further details regarding the restructuring.

On September 3, 2013, TransEnterix Surgical, Inc. a Delaware corporation (“TransEnterix Surgical”), and SafeStitch Medical, Inc., a Delaware corporation (“SafeStitch”) consummated a merger transaction whereby TransEnterix Surgical merged with a merger subsidiary of SafeStitch, with TransEnterix Surgical as the surviving entity in the merger (the “Merger”). As a result of the Merger, TransEnterix Surgical became a wholly owned subsidiary of SafeStitch. On December 6, 2013, SafeStitch changed its name to TransEnterix, Inc. and increased the authorized shares of common stock from 225,000,000 to 750,000,000, and authorized 25,000,000 shares of preferred stock, par value $0.01 per share.

On September 18, 2015, the Company entered into a Membership Interest Purchase Agreement, (the “Purchase Agreement”) with Sofar S.p.A., (“Sofar”) as seller, Vulcanos S.r.l. (“Vulcanos”), as the acquired company, and TransEnterix International, Inc. (“TransEnterix International”), 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 (the “Closing Date”) 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 (“TransEnterix Italia”). The Senhance Acquisition included all of the assets, employees and contracts related to the Senhance System. See Note 3 for a description of the related transactions.

As used herein, the term “Company” refers to the combination of SafeStitch and TransEnterix Surgical after giving effect to the Merger, and includes TransEnterix International, TransEnterix Italia, TransEnterix Europe S.Á.R.L, TransEnterix Europe S.Á.R.L, Bertrange, Swiss Branch, Lugano and TransEnterix Asia PTE. LTD. after giving effect to the Senhance Acquisition.

The Company operates in one business segment.

2. Summary of Significant Accounting Policies

Basis of Presentation

The Company has prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with the instructions to Form 10-Q and the standards of accounting measurement set forth in the Interim Reporting Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”). Consequently, the Company has not necessarily included in this Form 10-Q all information and footnotes required for audited financial statements. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements in this Form 10-Q contain all adjustments, consisting only of normal recurring adjustments, except as otherwise indicated, necessary for a fair statement of its financial position, results of operations, and cash flows of the Company for all periods presented. The results reported in these condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for any subsequent period or for the entire year. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited financial statements and the notes thereto included in the Company’s latest Annual Report on Form 10-K. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”) have been condensed or omitted in the accompanying interim consolidated financial statements. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. The accompanying Consolidated Financial Statements include the accounts of the Company and its direct and indirect wholly owned subsidiaries, SafeStitch LLC, TransEnterix Surgical, Inc., TransEnterix International, Inc., TransEnterix Italia S.r.l., TransEnterix Europe S.Á.R.L, TransEnterix Europe S.Á.R.L, Bertrange, Swiss Branch, Lugano and TransEnterix Asia PTE. LTD. All inter-company accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include identifiable intangible assets and goodwill, contingent consideration, warrant liabilities, stock compensation expense, restructuring and other charges, excess and obsolete inventory reserves, and deferred tax asset valuation allowances.

Cash and Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments with original maturities of 90 days or less at the time of purchase to be cash equivalents and investments with original maturities of between 91 days and one year to be short-term investments. In order to manage exposure to credit risk, the Company invests in high-quality investments rated at least A2 by Moody’s Investors Service or A by Standard & Poor.

Restricted cash at September 30, 2017 includes $6.0 million in a money market account, held in connection with the Company’s notes payable (see Note 12) and $386,000 in cash accounts held as collateral primarily under the terms of an office operating lease and automobile leases.

Fair Value of Financial Instruments

The carrying values of accounts receivable, interest receivable, accounts payable, and certain accrued expenses at September 30, 2017 and December 31, 2016, approximate their fair values due to the short-term nature of these items. The Company’s notes payable balance also approximates fair value as of September 30, 2017 and December 31, 2016, as the interest rates on the notes payable approximate the rates available to the Company as of these dates.

2. Summary of Significant Accounting Policies (Continued)

Concentrations and Credit Risk

The Company’s principal financial instruments subject to potential concentration of credit risk are cash and cash equivalents and investments held in money market accounts. The Company places cash deposits with a federally insured financial institution. The Company maintains its cash at banks and financial institutions it considers to be of high credit quality; however, the Company’s cash deposits may at times exceed the FDIC insured limit. Balances in excess of federally insured limitations may not be insured. The Company has not experienced losses on these accounts, and management believes that the Company is not exposed to significant risks on such accounts.

The Company’s accounts receivable are derived from net revenue to customers located throughout the world. The Company evaluates its customers’ financial condition and, generally, requires no collateral from its customers. The Company provides reserves for potential credit losses but has not experienced significant losses to date. The Company had six customers who constituted 100% of the Company’s net accounts receivable at September 30, 2017 and three customers who constituted 100% of the Company’s net accounts receivable at December 31, 2016.

Accounts Receivable

Accounts receivable are recorded at net realizable value, which includes an allowance for estimated uncollectable accounts. The allowance for uncollectible accounts was determined based on historical collection experience.

Inventories

Inventories are stated at the lower of cost (determined on a first-in, first-out basis) and net realizable value. Inventory costs include direct materials, direct labor, and normal manufacturing overhead. The Company records reserves, when necessary, to reduce the carrying value of inventory to its net realizable value. Management considers forecast demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. 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. Any inventory on hand at the measurement date in excess of the Company’s current requirements based on anticipated levels of sales is classified as long-term on the Company’s consolidated balance sheets.

Identifiable Intangible Assets and Goodwill

Identifiable intangible assets are recorded at cost, or when acquired as part of a business acquisition, at estimated fair value. Certain intangible assets are amortized over 7 to 10 years. Similar to tangible personal property and equipment, the Company periodically evaluates identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.  

Intellectual property consists of purchased patent rights and developed technology acquired as part of a business acquisition. Amortization of the patent rights is recorded using the straight-line method over the estimated useful life of the patents of 10 years. Amortization of the developed technology is recorded using the straight-line method over the estimated useful life of 7 years. This method approximates the period over which the Company expects to receive the benefit from these assets. See Note 14 for additional information related to the write-off of purchased patents in connection with the restructuring plan executed in May 2016.   

Indefinite-lived intangible assets, such as goodwill, are not amortized. The Company tests the carrying amounts of goodwill for recoverability on an annual basis at December 31 or when events or changes in circumstances indicate evidence a potential impairment exists, using a fair value based test. The Company continues to operate in one segment, which is considered to be the sole reporting unit and therefore, goodwill is tested for impairment at the enterprise level. See Note 9 for additional information related to goodwill impairment recorded during the second quarter of 2016.

2. Summary of Significant Accounting Policies (Continued)

In-Process Research and Development

In-process research and development (“IPR&D”) assets represent the fair value assigned to technologies that were acquired, which at the time of acquisition have not reached technological feasibility and have no alternative future use. IPR&D assets are considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. During the period that the IPR&D assets are considered indefinite-lived, they are tested for impairment on an annual basis, or more frequently if the Company becomes 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 upon regulatory approval, and the Company is 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, the Company 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. The IPR&D assets were acquired on September 21, 2015.

Property and Equipment

Property and equipment consists primarily of machinery, manufacturing equipment, demonstration equipment, computer equipment, furniture, and leasehold improvements, which are recorded at cost.

Depreciation is recorded using the straight-line method over the estimated useful lives of the assets as follows:

Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation and amortization are removed from the accounts and any resulting gain or loss is credited or charged to operations. Repairs and maintenance costs are expensed as incurred.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets for possible impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. To determine the recoverability of its long-lived assets, the Company evaluates the probability that future estimated undiscounted net cash flows will be less than the carrying amount of the assets. If such estimated cash flows are less than the carrying amount of the long-lived assets, then such assets are written down to their fair value. The Company’s estimates of anticipated cash flows and the remaining estimated useful lives of long-lived assets could be reduced in the future, resulting in a reduction to the carrying amount of long-lived assets.

Contingent Consideration

Contingent consideration is recorded as a liability and is the estimate of the fair value of potential milestone payments related to business acquisitions. Contingent consideration is 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 contingent consideration is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations and comprehensive loss.

2. Summary of Significant Accounting Policies (Continued)

Warrant Liabilities

The Company’s Series A Warrants and Series B Warrants (see Note 4) are measured at fair value using a simulation model which takes into account, as of the valuation date, factors including the current exercise price, the expected life of the warrant, the current price of the underlying stock, its expected volatility, holding cost and the risk-free interest rate for the term of the warrant (see Note 13). The warrant derivative liability is revalued at each reporting period and changes in fair value are 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 derivative 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.

Translation of Foreign Currencies

The functional currency of the Company’s operational foreign subsidiaries is Euros. The assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Income and expense items are translated at the average exchange rates prevailing during the period. The cumulative translation effect for a subsidiary using a functional currency other than the U.S. dollar is included in accumulated other comprehensive income or loss as a separate component of stockholders’ equity.

The Company’s intercompany accounts are denominated in the functional currency of the foreign subsidiary. Gains and losses resulting from the remeasurement of intercompany receivables that the Company considers to be of a long-term investment nature are recorded as a cumulative translation adjustment in accumulated other comprehensive income or loss as a separate component of stockholders’ equity, while gains and losses resulting from the remeasurement of intercompany receivables from a foreign subsidiary for which the Company anticipates settlement in the foreseeable future are recorded in the consolidated statements of operations and comprehensive loss. The net gains and losses included in net loss in the consolidated statements of operations and comprehensive loss for the nine months ended September 30, 2017 and 2016 were not significant.

Risk and Uncertainties

The Company is subject to a number of risks similar to other similarly-sized companies in the medical device industry. These risks include, without limitation, the historical lack of profitability; the Company’s ability to raise additional capital; its ability to successfully develop, clinically test and commercialize its products; the timing and outcome of the regulatory review process for its products; changes in the health care and regulatory environments of the United States, Italy, other countries in the European Union, and other countries in which the Company does, or intends, to operate; its ability to attract and retain key management, marketing and scientific personnel; competition from new entrants; its ability to successfully prepare, file, prosecute, maintain, defend and enforce patent claims and other intellectual property rights; its ability to successfully transition from a research and development company to a marketing, sales and distribution company; competition in the market for robotic surgical devices; and its ability to identify and pursue development of additional products.

Revenue Recognition

The Company’s revenue consists of product revenue resulting from the sales of systems, instruments and accessories, and service revenue. The Company recognizes 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. The Company generally recognizes revenue at the following points in time:

12

2. Summary of Significant Accounting Policies (Continued)

The Company’s system sale arrangements contain multiple elements including a system(s), instruments, accessories, and system service. The Company generally delivers 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 accessories, instruments, 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.

The Company’s 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.

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

Research and Development Costs

Research and development expenses primarily consist of engineering, product development and regulatory expenses, incurred in the design, development, testing and enhancement of our products. Research and development costs are expensed as incurred.

Stock-Based Compensation

The Company follows ASC 718 (“Stock Compensation”) and ASC 505-50 (“Equity-Based Payments to Non-employees”), which provide guidance in accounting for share-based awards exchanged for services rendered and requires companies to expense the estimated fair value of these awards over the requisite service period. For awards granted to non-employees, the Company determines the fair value of the stock-based compensation awards granted as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. If the fair value of the equity instruments issued is used, it is measured using the stock price and other measurement assumptions as of the earlier of either (1) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached, or (2) the date at which the counterparty’s performance is complete.

The Company recognizes compensation expense for stock-based awards based on estimated fair values on the date of grant for awards granted to employees. The Company uses the Black-Scholes-Merton option pricing model to determine the fair value of stock options. The fair value of restricted stock units is determined by the market price of the Company’s common stock on the date of grant. The expense associated with stock-based compensation is recognized on a straight-line basis over the requisite service period of each award.

The Company records as expense the fair value of stock-based compensation awards, including stock options and restricted stock units. Compensation expense for stock-based compensation was approximately $5,321,000 and $3,858,000 for the nine months ended September 30, 2017 and 2016, respectively.

The TransEnterix, Inc. 2007 Incentive Compensation Plan (the “Plan”) was originally approved by the Company’s board of directors, or the Board, and adopted by the majority of the Company’s stockholders on November 13, 2007. The Plan has been subsequently amended, and approved by stockholders, as required, to increase the number of shares available under the Plan and to make other changes.  As of May 25, 2017, the date of the Company’s annual meeting of stockholders for 2017, the number of shares of Common Stock authorized under the Plan is 25,940,000.

Income Taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets or liabilities for the temporary differences between financial reporting and tax basis of the Company’s assets and liabilities, and for tax carryforwards at enacted statutory rates in effect for the years in which the asset or liability is expected to be realized. The effect on deferred taxes of a change in tax rates is recognized in income during the period that includes the enactment date. In addition, valuation allowances are established when necessary to reduce deferred tax assets and liabilities to the amounts expected to be realized.

2. Summary of Significant Accounting Policies (Continued)

Segments

The Company operates in one business segment—the research, development and sale of medical device robotics to improve minimally invasive surgery. The Company’s chief operating decision maker (determined to be the Chief Executive Officer) does not manage any part of the Company separately, and the allocation of resources and assessment of performance are based on the Company’s consolidated operating results. Approximately 57% of the Company’s total consolidated assets are located within the U.S. as of September 30, 2017. The remaining assets are mostly located in Europe and are primarily related to the Company’s facility in Italy, and include goodwill, intellectual property, in-process research and development, other current assets, property and equipment, cash, accounts receivable and inventory of $79.0 million at September 30, 2017. Total assets outside of the U.S. excluding goodwill amounted to 43% and 40% of total consolidated assets at September 30, 2017 and December 31, 2016, respectively. All revenues recorded were outside of the U.S.

Impact of Recently Issued Accounting Standards  

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, Simplifying the Test for Goodwill Impairment. Under the new standard, goodwill impairment would be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying value of goodwill. This ASU eliminates existing guidance that requires an entity to determine goodwill impairment by calculating the implied fair value of goodwill by hypothetically assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. This ASU is effective prospectively to annual and interim impairment tests beginning after December 15, 2019, with early adoption permitted. The Company early adopted this ASU as of the beginning of fiscal year 2017. The adoption of this ASU did not have a material impact on the consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) which addresses changes to reduce the presentation diversity of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs, settlement of certain debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, and distributions received from equity method investees.  The guidance becomes effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. An entity that elects early adoption must adopt all of the amendments in the same period. The new standard will be applied retrospectively, but may be applied prospectively if retrospective application would be impracticable.  The Company is currently evaluating the guidance and has not determined the impact this standard may have on its consolidated statement of cash flows.

In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718) – Improvements to Employee Share-Based Payment Accounting. Under ASU 2016-09, the tax effects of stock compensation will be recognized as income tax expense or benefit in the income statement and the tax effects of exercised or vested awards will be treated as discrete items in the reporting period in which they occur. Along with other income tax cash flows, excess tax benefits will be classified as operating activities, and cash paid by an employer when directly withholding shares for tax withholding purposes will be classified as financing activities. Entities may make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current U.S. GAAP) or account for forfeitures when they occur. The threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions. For public companies, ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company adopted this ASU 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.

In February 2016, the FASB issued ASU 2016-02, Leases. The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company currently expects that upon adoption, ROU assets and lease liabilities will be recognized in the balance sheet in amounts that the Company does not expect will have a material impact on the consolidated financial statements based on the Company’s current leases.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP.

2. Summary of Significant Accounting Policies (Continued)

The updated guidance is effective for annual periods beginning after December 15, 2017, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). Due to limited sales, the Company has evaluated its contracts and has concluded that the impact of adopting the standard will have no material impact on its consolidated financial statements and related disclosures.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory (Topic 330). This update requires inventory within the scope of the standard to be measured at the lower of cost and net realizable value. Previous guidance required inventory to be measured at the lower of cost or market (where market was defined as replacement cost, with a ceiling of net realizable value and floor of net realizable value less a normal profit margin). This update is effective for annual and interim periods beginning after December 15, 2016. The Company adopted these provisions in the first quarter of fiscal year 2017 with no material impact on its consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial assets on the balance sheet or the accompanying notes to the financial statements and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company does not believe the adoption of this guidance will have a material impact on its consolidated financial statements or related footnote disclosures.

Except as noted above, there have been no significant changes to our assessment of the impact of recently issued accounting standards included in Note 2 of Notes to Consolidated Financial Statements in our Fiscal 2016 Form 10-K.

3. Acquisition of Senhance Surgical Robotic System

On September 21, 2015, the Company completed the strategic acquisition, through its wholly owned subsidiary TransEnterix International, from Sofar, 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 and changed the name of the acquired company from Vulcanos S.r.l. to TransEnterix Italia S.r.l.

Under the terms of the Purchase Agreement, the consideration consisted of the issuance of 15,543,413 shares of the Company’s common stock (the “Securities Consideration”) and approximately $25.0 million U.S. Dollars and €27.5 million Euro in cash consideration (the “Cash Consideration”). The Securities Consideration was issued in full at the closing of the Senhance Acquisition; the Cash Consideration was or will be paid in four tranches, as follows:

(1) $25.0 million of the Cash Consideration was paid at closing.

(2) On December 30, 2016, the Company entered into an Amendment to the Purchase Agreement (the “Amendment”) to restructure the terms of the second tranche of the Cash Consideration (the “Second Tranche”). Under the Amendment, the Second Tranche was restructured to be paid through the (A) the issuance of 3,722,685 shares of the Company’s common stock with an aggregate fair market value of €5.0 million and (B) the payment of €5.0 million in cash upon the occurrence of either (i) receipt of clearance from the FDA for the Senhance System; or (ii) the Company having cash on hand of at least $50.0 million, or (iii) successfully completing a financing, raising at least $50.0 million in gross proceeds after September 2015, exclusive of any financing proceeds related to the December 2016 purchase agreement between the Company and Lincoln Park Capital Fund, LLC; with payment of simple interest at a rate of 9.0% per annum beginning on December 31, 2016. The Five Million Euro (€ 5.000.000) cash payment began to accrue simple interest at a rate of 9% per annum beginning on December 31, 2016 and will continue to accrue interest until paid in full. Such payment will be due immediately upon the completion of one of the three events identified above, except that the Company may, in its sole discretion, defer payment until December 31, 2017 in the event that any of the three events occurs before December 31, 2017. Prior to December 30, 2016, the second tranche of the Cash Consideration of €10.0 million was payable after the achievement of both of the following milestones (i) the earlier of approval from the FDA for the Senhance System or December 31, 2016, and (ii) the Company having cash on hand of at least $50.0 million, or successfully completing a financing, raising at least $50.0 million in gross proceeds; with payment of simple interest at a rate of 9.0% per annum between the achievement of the first milestone event and the payment date.

3. Acquisition of Senhance Surgical Robotic System (Continued)

(3) The third tranche of the Cash Consideration (the “Third Tranche”) of €15.0 million shall be payable upon achievement of trailing revenues from sales or services contracts of the Senhance System of at least €25.0 million over a calendar quarter.

(4) The fourth tranche of the Cash Consideration of €2.5 million shall be payable by December 31 of each year as reimbursement for certain debt payments made by Sofar under an existing Sofar loan agreement in such year, with payments beginning as of December 31, 2016. As of September 30, 2017 and December 31, 2016, the Company had paid €1.1 million of the fourth tranche.

The Third Tranche will be payable even if the Second Tranche is not then payable. In addition, the Second Tranche and Third Tranche payments will be accelerated in the event that (i) the Company or TransEnterix International is acquired, (ii) the Company significantly reduces or suspends selling efforts of the Senhance System, or (iii) the Company acquires a business that offers alternative products that are directly competitive with the Senhance System. Payments of the fourth tranche of contingent consideration was $395,000 for the three months ended September 30, 2017.

Under the Purchase Agreement, 10% of the Securities Consideration was held in escrow to support Sofar’s representations and warranties under the Purchase Agreement. In accordance with a related escrow agreement, the escrowed shares were released in September 2016. The Company, a subsidiary and Sofar also entered into a Security Agreement, which provided that 10% of the membership interests of TransEnterix Italia had a lien placed thereon by and in favor of Sofar to support the Company’s representations and warranties under the Purchase Agreement. The security interest period was twenty-four months after the closing of the Senhance Acquisition and expired on September 21, 2017.

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.

In connection with the Senhance Acquisition, the Company also entered into a Registration Rights Agreement, dated as of September 21, 2015, with Sofar, pursuant to which the Company 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 the Company 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

The Senhance Acquisition was accounted for as a business combination utilizing the methodology prescribed in ASC 805. The purchase price for the Senhance Acquisition was allocated to the assets acquired and liabilities assumed based on their estimated fair values.

4. Fair Value

The Company holds certain assets and liabilities that are required to be measured at fair value on a recurring basis. These assets and liabilities include available for sale securities classified as cash and cash equivalents, restricted cash, contingent consideration, and warrant liabilities. ASC 820-10 (“Fair Value Measurement Disclosure”) requires the valuation using a three-tiered approach, which requires that fair value measurements be classified and disclosed in one of three tiers. These tiers are: Level 1, defined as quoted prices in active markets for identical assets or liabilities; Level 2, defined as valuations based on observable inputs other than those included in Level 1, such as quoted prices for similar assets and liabilities in active markets, or other inputs that are observable or can be corroborated by observable input data; and Level 3, defined as valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants. The Company did not have any transfers of assets and liabilities between Level 1, Level 2, and Level 3 of the fair value hierarchy during the nine or three months ended September 30, 2017.

16

4. Fair Value (Continued)

For assets and liabilities recorded at fair value, it is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy. Fair value measurements for assets and liabilities where there exists limited or no observable market data and therefore, are based primarily upon estimates, are often calculated based on the economic and competitive environment, the characteristics of the asset or liability and other factors. Therefore, the results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset or liability. Additionally, there may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values. The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.

As prescribed by U.S. GAAP, the Company groups assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. An adjustment to the pricing method used within either Level 1 or Level 2 inputs could generate a fair value measurement that effectively falls in a lower level in the hierarchy.

The determination of where an asset or liability falls in the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures and based on various factors, it is possible that an asset or liability may be classified differently from period to period. However, the Company expects changes in classifications between levels will be rare.

The following are the major categories of assets measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016, using quoted prices in active markets for identical assets (Level 1); significant other observable inputs (Level 2); and significant unobservable inputs (Level 3):

17

4. Fair Value (Continued)

The Company’s financial liabilities include contingent consideration potentially payable to Sofar related to the Senhance Acquisition in September 2015 (see Note 3). This liability is reported as Level 3 as estimated fair value of the contingent consideration related to the acquisition requires significant management judgment or estimation and is calculated using the income approach, using various revenue and cost assumptions and applying a probability to each outcome. The change in fair value of the contingent consideration of $1,226,000 and $1,700,000 for the nine months ended September 30, 2017 and 2016, respectively, was primarily due to the effect of the change in discount rate, passage of time on the fair value measurement and the impact of foreign currency exchange rates. Adjustments associated with the change in fair value of contingent consideration are included in the Company’s consolidated statements of operations and comprehensive loss.

On April 28, 2017, the Company sold 24.9 million units (the “Units”), each consisting of one share of the Company’s common stock, par value $0.001 per share (the “Common Stock”), a Series A warrant to purchase one share of Common Stock with an exercise price of $1.00 per share  (the “Series A Warrants”), and a Series B warrant to purchase 0.75 shares of Common Stock with an exercise price of $1.00 per share (the “Series B Warrants,” together with the Series A Warrants, the “Warrants”), at an offering price of $1.00 per Unit. Each Series A Warrant was exercisable 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 Section 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 (see Note 19). Each Series B Warrant 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.

The fair value of the Series A Warrants of $2.5 million at the date of issuance was estimated using the Black-Scholes Merton model which used the following inputs: term of 1 year, risk free rate of 1.07%, no dividends, volatility of 73.14%, and share price of $0.65 per share based on the trading price of the Company’s common stock. The fair value of the Series B Warrants of $6.2 million at the date of issuance was estimated using the Black-Scholes Merton model which used the following inputs: term of 5 years, risk free rate of 1.81%, no dividends, volatility of 73.14%, and share price of $0.65 per share based on the trading price of the Company’s common stock. The fair value of the Series A Warrants of $11.4 million at September 30, 2017 was estimated using the Black-Scholes Merton model which used the following inputs: term of 7 months, risk free rate of 1.22%, no dividends, volatility of 87.7%, and share price of $1.43 per share based on the trading price of the Company’s common stock. The fair value of the Series B Warrants of $19.7 million at September 30, 2017 was estimated using the Monte Carlo valuation model which used the following inputs: term of 4.57 years, risk free rate of 1.86%, volatility of 87.7%, share price of $1.43 per share based on the trading price of the Company’s common stock, and probability of additional financing in 2018 and 2019 of 100%. The change in fair value of warrants for the nine months ended September 30, 2017 of $25.2 million and three months ended September 30, 2017 of $22.9 million was included in the Company’s consolidated statements of operations and comprehensive loss.

The following table presents quantitative information about the inputs and valuation methodologies used for the Company’s fair value measurements of Contingent consideration classified in Level 3 as of December 31, 2016 and September 30, 2017:

4. Fair Value (Continued)

The following table summarizes the change in fair value, as determined by Level 3 inputs, for all assets and liabilities using unobservable Level 3 inputs for the nine months ended September 30, 2017:

5. Accounts Receivable, Net

The following table presents the components of accounts receivable:

6. Inventories

The components of inventories are as follows:

As disclosed in Note 14, the Company executed a restructuring plan in May 2016 and wrote down inventory related to the SurgiBot System.  The write down of inventory of $2.6 million is included in the accompanying consolidated statement of operations and comprehensive loss for the nine months ended September 30, 2016.  There were no such write-downs for the three and nine month periods ended September 30, 2017.

7. Other Current Assets

The following table presents the components of other current assets:

8. Property and Equipment

Property and equipment consisted of the following:

As disclosed in Note 14, the Company executed a restructuring plan in May 2016 and disposed of certain long-lived assets, primarily equipment and fixtures related to the SurgiBot System.  The disposal of long-lived assets of $1.0 million is included as a component of restructuring and other charges in the accompanying consolidated statement of operations and comprehensive loss for the nine months ended September 30, 2016.  There were no such disposals for the three and nine months ended September 30, 2017.

Depreciation expense was $1,820,000 and $1,498,000 for the nine months ended September 30, 2017 and 2016, respectively. Depreciation expense was $678,000 and $446,000 for the three months ended September 30, 2017 and 2016, respectively.

9. Goodwill, In-Process Research and Development and Intellectual Property

Goodwill

Goodwill of $93.8 million was recorded in connection with the Merger, as described in Note 1, and goodwill of $38.3 million was recorded in connection with the Senhance Acquisition, as described in Note 3. The carrying value of goodwill and the change in the balance for the nine months ended September 30, 2017 is as follows:

20

9. Goodwill, In-Process Research and Development and Intellectual Property (Continued)

Accumulated impairment of goodwill as of September 30, 2017 was $61.8 million.

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 the Company’s one reporting unit may not be recoverable. 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. Prior to adopting ASU 2017-04 as of the beginning of fiscal year 2017, goodwill was tested for impairment 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.

The Company determined the fair value of the reporting unit using a discounted cash flow analysis derived from the Company’s 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, the Company recorded goodwill impairment of $61.8 million during the second quarter of 2016.

The Company 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 the Company’s single reporting unit is less than its carrying amount. Therefore, the two-step goodwill impairment test for the reporting unit was not necessary at December 31, 2016. During the second quarter of 2017, the Company’s stock price experienced a significant decline. The Company performed a Step 1 goodwill impairment test as of the second quarter and determined that no charge to goodwill for impairment was required during the second quarter of 2017. No charge for goodwill impairment was required during the third quarter of 2017.

In-Process Research and Development

As described in Note 3, on September 21, 2015, the Company acquired all of the assets related to the Senhance System and recorded $17.1 million of IPR&D. The estimated fair value of the IPR&D was determined using a probability-weighted income approach, which discounts expected future cash flows to present value. The projected cash flows were based on certain key assumptions, including estimates of future revenue and expenses, taking into account the stage of development of the technology at the acquisition date and the time and resources needed to complete development. The Company used a discount rate of 45% and cash flows that have been probability adjusted to reflect the risks of product commercialization, which the Company believes are appropriate and representative of market participant assumptions.

The carrying value of the Company’s IPR&D assets and the change in the balance for the nine months ended September 30, 2017 is as follows:

21

9. Goodwill, In-Process Research and Development and Intellectual Property (Continued)

Intellectual Property

As described in Note 3, on September 21, 2015, the Company acquired all of the developed technology related to the Senhance System and recorded $48.5 million of intellectual property. The estimated fair value of the intellectual property was determined using a probability-weighted income approach, which discounts expected future cash flows to present value. The projected cash flows were based on certain key assumptions, including estimates of future revenue and expenses, taking into account the stage of development of the technology at the acquisition date and the time and resources needed to complete development. The Company used a discount rate of 45% and cash flows that have been probability adjusted to reflect the risks of product commercialization, which the Company believes are appropriate and representative of market participant assumptions.

In November 2016, the Company agreed to enter into a technology and patents purchase agreement with Sofar to acquire from Sofar certain technology and intellectual property rights related to the Senhance Acquisition, and formerly licensed by the Company.  The acquisition price was $400,000.

As disclosed in Note 14, the Company executed a restructuring plan in May 2016 and wrote-off certain intellectual property consisting of patents related to the SurgiBot System.  The write-off of intellectual property of $1.6 million is included as a component of restructuring and other charges in the accompanying consolidated statements of operations and comprehensive losses for the nine months ended September 30, 2016.  There were no such write offs for the three and nine months ended September 30, 2017.

The components of gross intellectual property, accumulated amortization, and net intellectual property as of September 30, 2017 and December 31, 2016 are as follows:

10. Income Taxes

Income taxes have been accounted for using the liability method in accordance with ASC 740 Income Taxes. The Company computes its interim provision for income taxes by applying the estimated annual effective tax rate method. The Company estimates an annual effective tax rate of 4.1% for the year ending December 31, 2017. This rate does not include the impact of any discrete items.  The Company incurred losses for the nine month periods ended September 30, 2017 and is forecasting additional losses through the year, resulting in an estimated net loss for both financial statement and tax purposes for the year ending December 31, 2017. Due to the Company’s history of losses, there is not sufficient evidence to record a net deferred tax asset associated with the U.S., Luxembourg, and Swiss operations. Accordingly, a full valuation allowance has been recorded related to the net deferred tax asset in those jurisdictions. Deferred tax assets and liabilities related to the TransEnterix Italia subsidiary have been recorded as a component of purchase accounting as of the acquisition date. The deferred tax benefit during the nine months ended September 30, 2017 and 2016, was approximately $2.3 million and $4.7 million, respectively.  

There is no net deferred tax asset recorded in relation to TransEnterix Italia and accordingly no valuation allowance has been recorded in that jurisdiction.

The Company’s effective tax rate for each of the nine month periods ended September 30, 2017 and 2016 was 3.3% and 4.3%, respectively. The effective tax rate for September 30, 2016 includes the tax effect of the Company’s goodwill impairment charge, which is being treated as a discrete item for the quarter ending June 30, 2016.   At September 30, 2017, the Company had no unrecognized tax benefits that would affect the Company’s effective tax rate.

22

11. Accrued Expenses

The following table presents the components of accrued expenses:

12. Notes Payable

On May 10, 2017, the Company and its domestic subsidiaries, as co-borrowers, entered into a Loan and Security Agreement (the “Innovatus Loan Agreement”) with Innovatus Life Sciences Lending Fund I, LP, as Lender and Collateral Agent (the “Lender”).  Under the Innovatus Loan Agreement, the Lender 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, including Senhance Clearance (as defined below). 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 the 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 FDA (“Senhance Clearance”) by May 30, 2018 (each such milestone, an “Interest-Only Milestone”).

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%) (the “Final Fee”); provided, however, that in the event the Company refinances its obligations with the Lender after Senhance Clearance, no Final Fee or Prepayment Fee (as defined below) will be due thereunder; 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 (the “Prepayment Fee”).

23

12. Notes Payable (Continued)

In connection with the funding, the Company paid a facility fee of $170,000 on the date of funding of the first tranche and incurred additional debt issuance costs of approximately $1.2 million, recorded as debt discount.  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 estimated the fair value of the warrants to be $300,000. The value of the warrants was classified as equity and recorded as a discount to the loan.  The debt discount is amortized as interest expense using the effective interest method over the life of the loan.

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 least 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.

The future principal payments under the Innovatus Loan Agreement are as follows:

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 (the “Prior Lenders”), which loan and security agreement, as subsequently amended and restated is referred to as the “SVB Loan Agreement.” The Company recognized a loss of $308,000 on the extinguishment of notes payable for the nine months ended September 30, 2017, which is included in interest expense on the consolidated statements of operations and comprehensive loss. The Company paid $1.3 million in final payment obligations and $255,000 in facility fees under the SVB Loan Agreement upon repayment.

The SVB Loan Agreement was initially entered into on January 17, 2012. In connection with the Merger, the Company assumed and became the borrower under the SVB Loan Agreement.

On August 14, 2015, the Company entered into the First Amendment to the SVB Loan Agreement (the “First Amendment”) with the Prior Lenders. The first tranche of the First Amendment increased the Company’s borrowings at August 14, 2015 from $10,000,000 to $20,000,000. The First Amendment allowed for interest-only payments at 7.5% per annum through April 30, 2016 and had a maturity date of October 1, 2018.

On September 18, 2015, in connection with entry into the Purchase Agreement with Sofar S.p.A. (see Note 3 for a description of the related transactions), the Company and the Prior Lenders entered into the Consent and Second Amendment (the “Second Amendment”) to the SVB Loan Agreement. The Second Amendment modified the period in which the Company could make interest-only payments at 7.5% per annum on the term loans until January 31, 2016. The Second Amendment had a maturity date of July 1, 2018.

In addition, in connection with the borrowings under the SVB Loan Agreement, the Company issued warrants to the Prior Lenders to purchase shares of the Company’s common stock amounting to an aggregate of 430,815 warrants under the SVB Loan Agreement. The warrants expire seven years from their respective issue date.

12. Notes Payable (Continued)

In accordance with ASC 470-50 Debt – Modifications and Extinguishments, it was determined that a debt refinancing of the SVB Loan Agreement on September 26, 2014, was considered to be a debt modification. Accordingly, the Company recorded approximately $129,000 of debt discount, consisting of the $75,000 facility fee and the relative fair value of warrants on the issue date of $54,000. Additionally, approximately $30,000 of legal fees was recorded as a result of the transaction. The debt discount and deferred financing costs were amortized over the life of the new debt agreement using the effective interest method into interest expense, net, until the debt was extinguished in May 2017.

In accordance with ASC 470-50 Debt – Modifications and Extinguishments, it was determined that debt refinancings of the SVB Loan Agreement on August 14, 2015, September 18, 2015, April 19, 2016 and September 7, 2016 were considered to be debt modifications. The Company recorded a debt discount of approximately $210,000 for these amendments. Accordingly, the unamortized debt discount was presented as a reduction of the related debt liability in the Company’s consolidated balance sheet. The debt discount was amortized over the life of the new debt agreement using the effective interest method into interest expense, net, until the debt was extinguished in May 2017.

In connection with the issuance of the notes payable and amendments under the SVB Loan Agreement, TransEnterix Surgical incurred approximately $371,000 in debt issuance costs paid to the Prior Lenders and third parties and $280,000 in debt issuance costs related to issuance of warrants to the Prior Lenders. The unamortized balance of $107,000 as of December 31, 2016, was amortized using the effective interest method, until the debt was extinguished in May 2017. At the time of extinguishment in May 2017, $63,000 of unamortized debt issuance costs were included in the loss on extinguishment of notes payable.

13. Warrants

On March 22, 2013, SafeStitch entered into a stock purchase agreement with approximately 17 investors (the “2013 PIPE Investors”) pursuant to which the 2013 PIPE Investors purchased an aggregate of approximately 2,420,000 shares of common stock at a price of $1.25 per share for aggregate consideration of approximately $3.0 million. Included in this private placement was the issuance of warrants to purchase approximately 1,209,600 common shares, representing one warrant for every two common shares purchased, with an exercise price of $1.65 per share and five year expiration. Among the 2013 PIPE Investors purchasing shares were related parties who purchased 1.28 million shares and received 640,000 warrants. There were approximately 1.2 million warrants outstanding that were assumed as of the Merger. None of these warrants were exercised during the nine months ended September 30, 2017.

On January 17, 2012, TransEnterix Surgical entered into the original Loan Agreement with the Prior Lenders. Pursuant to such agreement, TransEnterix Surgical issued preferred stock warrants to the Prior Lenders on January 17, 2012 and December 21, 2012, respectively, to purchase shares of TransEnterix Surgical preferred stock. The preferred stock warrants expire 10 years from the issue date. The preferred stock warrants were remeasured immediately prior to the Merger. As of the Merger, the preferred stock warrants converted to common stock warrants, adjusted based on a Merger exchange ratio of 1.1533, and the preferred stock warrant liability was reclassified to additional paid-in capital. These warrants are exercisable for an aggregate of approximately 279,588 shares of common stock, with an exercise price of $1.45 per share. During the year ended December 31, 2013, 139,794 of these warrants were exercised in a cashless transaction for 112,766 shares of common stock. None of these warrants were exercised during the nine months ended September 30, 2017.

On September 26, 2014, the Company entered into an amendment to its SVB Loan Agreement with the Prior Lenders. In connection with the first tranche borrowings under such amendment, the Company issued 38,324 common stock warrants to the Prior Lenders to purchase shares of the Company’s common stock, with an exercise price of $4.015 per share. The warrants expire seven years from their respective issue date. The Company concluded that the warrants are considered equity instruments. The warrants were recognized at the relative fair value on the issuance date as a debt discount and will be amortized using the effective interest method from issuance to the maturity of the term loans. None of these warrants were exercised during the nine months ended September 30, 2017.

On August 14, 2015, in connection with an amendment to the SVB Loan Agreement and first tranche borrowings thereunder, the Company issued 112,903 common stock warrants to the Prior Lenders to purchase shares of the Company’s common stock, with an exercise price of $3.10 per share. The warrants expire seven years from their respective issue date. The Company concluded that the warrants are considered equity instruments. The warrants were recognized at the relative fair value on the issuance date as a debt discount and will be amortized using the effective interest method from issuance to the maturity of the note. None of these warrants were exercised during the nine months ended September 30, 2017.

25

13. Warrants (Continued)

On April 28, 2017, the Company sold 24.9 million Units, each consisting of one share of Common Stock, a Series A Warrant to purchase one share of Common Stock with an exercise price of $1.00 per share, and a Series B Warrant to purchase 0.75 shares of Common Stock with an exercise price of $1.00 per share at an offering price of $1.00 per Unit.  Each Series A Warrant may 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 Section 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 (see Note 19).

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 (see Note 19).

The exercise prices and the number of shares issuable upon exercise of each of the 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 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 prices of each of the Warrants. The exercisability of the Warrants may be limited if, upon exercise, the holder or any of its affiliates would beneficially own more than 4.99% of the Common Stock. If, at any time Warrants are outstanding, any fundamental transaction occurs, as described in the 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 Warrant holders. Additionally, in the event of a fundamental transaction, each Warrant holder will have the right to require the Company, or its successor, to repurchase the Warrants for an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of such Warrants. As of September 30, 2017, 5,204,495 and 0 Series A warrants and Series B warrants, respectively, were exercised.   

On May 10, 2017, in connection with the Innovatus Loan Agreement, the Company issued warrants to the Lender to purchase shares of the Company’s common stock.  The warrants are issued on the funding date of each tranche and will expire five (5) years from such issue date. The warrant issued in connection with funding of the first tranche will 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. None of these warrants were exercised as of September 30, 2017.

On September 12, 2017, the Company entered into a service agreement with a third party vendor. In connection with the service agreement, the Company issued 950,000 common stock warrants (“Service Warrants”) to purchase shares of the Company’s common stock, with an exercise price of $1.00 per share. The Service Warrants vest as follow: (a) twenty-five percent (25%) on the date of execution of the services agreement; (b) fifty percent (50%) upon completion of hiring the sales team; and (c) the remaining twenty-five percent (25%) upon achieving cumulative product revenue of $15.0 million. The Service Warrants expire ten years from their issue date. The Company concluded that the Service Warrants are considered equity instruments. The fair value of the Service Warrants on the issuance date was determined using a Black-Scholes Merton model. The initial expense of $0.6 was recognized as of September 30, 2017.  The fair value of the remaining Service Warrants will be updated each reporting period and the expense will be recorded over the service period. None of these warrants were exercised as of September 30, 2017.

14. 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. In May 2016, the Company implemented a restructuring plan.  Under the restructuring plan, the Company reduced headcount, discontinued efforts on the SurgiBot System, and cancelled certain contracts.  The restructuring charges amounted to $5.7 million, of which $2.6 million was included as inventory write down related to restructuring and $3.1 million was included as restructuring and other charges in the consolidated statements of operations and comprehensive loss, during the second quarter of 2016.

The restructuring and other charges of $3.1 million 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 disposal of long-lived assets for the abandonment of certain equipment and tooling directly relating to the SurgiBot System and $1.6 million related to the write-off of intellectual property for certain patents also relating to the SurgiBot System.

15. Equity Line Financing, Controlled Equity Offering and Public Offering of Common Stock

On April 28, 2017, the Company sold 24.9 million 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 a public offering price of $1.00 per unit for aggregate gross proceeds of $24.9 million in an underwritten firm commitment public offering. Net proceeds after issuance costs were $23.2 million, assuming no exercise of the warrants. The closing of the public offering occurred on May 3, 2017.

On December 16, 2016, the Company entered into a purchase agreement (the “LPC Purchase Agreement”) with Lincoln Park Capital Fund, LLC, (“Lincoln Park”), pursuant to which the Company had the right to sell to Lincoln Park up to an aggregate of $25.0 million in shares of the Company’s common stock, (the “Common Stock”), subject to certain limitations and conditions set forth in the LPC Purchase Agreement. The Company issued to Lincoln Park 345,421 shares of Common Stock as commitment shares in consideration for the LPC Purchase Agreement through April 27, 2017. Sales under the LPC Purchase Agreement for the year ended December 31, 2016 were 300,000 shares, with gross proceeds of $412,500 and net proceeds of $392,500. Sales under the LPC Purchase Agreement for the nine months ended September 30, 2017 were 3,972,741 shares, with gross and net proceeds of $5,304,000. Effective April 27, 2017, the Company terminated the LPC Purchase Agreement. The LPC Purchase Agreement provided the Company with an election to terminate the Purchase Agreement for any reason or for no reason by delivering a notice to Lincoln Park, and the Company did not incur any early termination penalties in connection with the termination of the LPC Purchase Agreement.

On February 20, 2015, the Company entered into a Controlled Equity Offering^SM Sales Agreement (the “2015 Sales Agreement”) with Cantor Fitzgerald & Co. (“Cantor”), as sales agent, pursuant to which the Company sold through Cantor, from time to time, up to $25.0 million in shares of common stock in an at-the-market offering. The Company pays Cantor a commission of approximately 3% of the aggregate gross proceeds received from all sales of common stock under the Sales Agreement. Sales under the 2015 Sales Agreement have been fully sold as of February 9, 2016, with cumulative shares of 7,724,488, gross proceeds of $25.0 million and net proceeds of $24.0 million.

On February 9, 2016, the Company entered into a Controlled Equity Offering^SM Sales Agreement (the “2016 Sales Agreement”) with Cantor, as sales agent, pursuant to which the Company can sell through Cantor, from time to time, up to $43.6 million in shares of common stock in an at-the-market offering. The Company pays Cantor a commission of approximately 3% of the aggregate gross proceeds received from all sales of common stock under the 2016 Sales Agreement. The 2016 Sales Agreement was terminated, effective September 10, 2017.

On August 31, 2017, the Company entered into an At-the-Market Equity Offering Sales Agreement (the “2017 Sales Agreement”) with Stifel, Nicolaus & Company, Incorporated (“Stifel”), as sales agent, pursuant to which the Company can sell through Stifel, from time to time, up to $50.0 million in shares of common stock in an at-the-market offering. The Company pays Stifel a commission of approximately 3% of the aggregate gross proceeds received from all sales of common stock under the 2017 Sales Agreement. Unless otherwise terminated earlier, the 2017 Sales Agreement continues until all shares available under the Sales Agreement have been sold (see Note 19).

27

15. Equity Line Financing, Controlled Equity Offering and Public Offering of Common Stock (Continued)

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):

16. Basic and Diluted Net Loss per Share

Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed giving effect to all dilutive potential common shares that were outstanding during the period. Diluted potential common shares consist of incremental shares issuable upon exercise of stock options and warrants and restricted stock units. In computing diluted net loss per share for the three and nine months ended September 30, 2017 and 2016, no adjustment has been made to the weighted average outstanding common shares as the assumed exercise of outstanding options and warrants and restricted stock units would be anti-dilutive.

17. Related Person Transactions

On September 18, 2015, TransEnterix Italia entered into a services agreement for receipt of administrative services from Sofar and payment of rent to Sofar, a stockholder that owned approximately 12.4% and 13.5% of the Company’s common stock at September 30, 2017 and 2016, respectively. Expenses under this agreement were approximately $52,000 and $162,000 for the nine months ended September 30, 2017 and 2016, respectively.

In November 2016, the Company agreed to enter into a technology and patents purchase agreement with Sofar to acquire from Sofar certain technology and intellectual property rights related to the Senhance Acquisition, and formerly licensed by the Company.  The acquisition price was $400,000.

As discussed in Note 3, in September 2015, the Company completed the Senhance Acquisition using a combination of cash, stock and potential post-acquisition milestone payments. On December 30, 2016, the Company entered into an Amendment to the Senhance Acquisition purchase agreement with Sofar 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.  On January 4, 2017, the Company issued to Sofar 3,722,685 shares of the common stock with a fair value of €5.0 million. 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.

18. Commitments and Contingencies

Legal Proceedings  

When determining the estimated probable loss or range of losses, significant judgment is required to be exercised in order to estimate the amount and timing of the loss to be recorded.  Estimating an amount or range of possible losses resulting from litigation proceedings is inherently difficult and requires an extensive degree of judgment, particularly where the matters involve indeterminate claims for monetary damages, are in the early stages of the proceedings, and are subject to appeal.  In addition, because most legal proceedings are resolved over extended periods of time, potential losses are subject to change due to, among other things, new developments, changes in legal strategy, the outcome of intermediate procedural and substantive rulings and other parties’ settlement posture and their evaluation of the strength or weakness of their case against the Company.  For these reasons, the Company is currently unable to predict the ultimate timing or outcome of, or reasonably estimate the possible losses or a range of possible losses resulting from, the matters described below. Based on information currently available, the Company does not believe that any reasonably possible losses arising from currently pending legal matters will be material to the Company’s results of operations or financial condition. However, in light of the inherent uncertainties involved in such matters, an adverse outcome in one or more of these matters could materially and adversely affect the Company’s financial condition, results of operations or cash flows in any particular reporting period.

28

18. Commitments and Contingencies (Continued)

No liability or related charge was recorded to earnings in the Company’s consolidated financial statements for legal contingencies for the nine months ended September 30, 2017 or the year ended December 31, 2016.

On June 2, 2016 a stockholder filed a putative class action complaint, Ashok V. Bankley, individually and on behalf of all others similarly situated vs. TransEnterix, Inc., Todd M. Pope and Joseph P. Slattery , in the United States District Court for the Eastern District of North Carolina (Case No. 5:16-cv-00313-D) (the “Initial Complaint”), against the Company and two of its executive officers on behalf of all persons who purchased or otherwise acquired the Company’s common stock between February 10, 2016 and May 10, 2016.  On August 4, 2016, the defendants filed a motion to dismiss the Initial Complaint for failure to state a claim under the securities laws.   On August 30, 2016, the court appointed Randall Clark, Samir Patel, the Underhill Cemetery Association, and the North Underhill Cemetery Association as the lead plaintiffs in the Initial Complaint, and also provided the plaintiffs an opportunity to amend the Initial Complaint.  On September 26, 2016, the lead plaintiffs filed an Amended Complaint.  Among other things, the Amended Complaint asserted revised claims against the Company and Messrs. Pope and Slattery, and added claims against certain current and former members of the Company’s Board of Directors, and Cantor Fitzgerald & Co., the sales agent under the 2016 Sales Agreement, under which the Company offered and sold, through Cantor, shares of common stock in its 2016 ATM Offering.   The Amended Complaint alleged that the defendants made false and misleading public statements related to the Company's SurgiBot System and its 510(k) application in violation of certain federal securities laws.  The Amended Complaint sought class certification of a class consisting of all persons who purchased or otherwise acquired the Company’s common stock between February 10, 2016 and May 10, 2016, class certification of a subclass of persons who purchased or otherwise acquired the Company’s common stock in connection with the 2016 ATM Offering between February 9, 2016 and April 19, 2016, unspecified monetary damages, costs, and attorneys’ fees.  On November 8, 2016, the defendants moved to dismiss the Amended Complaint, which the lead plaintiffs later opposed.   On September 22, 2017, the court entered an order granting the motions to dismiss.  On October 6, 2017, the court entered final judgment in favor of the defendants dismissing the putative securities class action with prejudice.

On July 8, 2016, a stockholder filed a different putative derivative complaint, captioned Otto Pikal v. Todd M. Pope, et al., in the General Court of Justice, Superior Court Division, Wake County, North Carolina (case number 16CV008930) (the “Pikal Action”), on behalf of the Company against certain of our current officers and directors.  The complaint alleges, among other things, that the defendants breached their fiduciary duties by disseminating false and misleading information to the Company’s shareholders relating to the Company’s SurgiBot System and its 510(k) application in violation of certain federal securities laws and by failing to ensure that the Company maintained adequate internal controls.  The complaint seeks, among other things, unspecified monetary damages and an order directing the Company to take steps to improve its corporate governance and to protect the Company and its stockholders from future wrongdoing such as that alleged in the complaint. On September 29, 2016, the court entered an order staying the Pikal Action pending resolution of the motion to dismiss the Amended Complaint in the Bankley Action.

On March 3, 2017, a different stockholder filed another putative class action complaint on behalf of the Company, captioned Scott Maine vs. Paul LaViolette, et al., in the Court of Justice, Superior Court Division, Wake County, North Carolina (case number 17CV002590) (the “Maine Action”).  The complaint in the Maine Action is substantially similar to the complaint in the Pikal Action, asserting similar claims and seeking similar relief against largely the same group of defendants named in the complaint in the Pikal Action.  On April 11, 2017, the court entered an order staying the Maine Action pending resolution of the motion to dismiss the Amended Complaint in the Bankley Action.

19. Subsequent Events

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the related notes to our consolidated financial statements included in this report. The following discussion contains forward-looking statements. See cautionary note regarding “Forward-Looking Statements” at the beginning of this report.

Overview

TransEnterix, Inc. (the “Company,” “we” or “us”) is a medical device company that is pioneering the use of robotics to improve minimally invasive surgery by addressing the clinical challenges associated with current laparoscopic and robotic options. The Company is focused on the commercialization of its Senhance™ Surgical Robotic System (the “Senhance System”), a multi-port robotic system that brings the advantages of robotic surgery to patients while enabling surgeons with innovative technology such as haptic feedback and eye sensing camera control. The Company also developed the SurgiBot™ System, a single-port, robotically enhanced laparoscopic surgical platform. 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 Section 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. The SurgiBot System is not available for sale in any market.

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 (“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 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. 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.

In May 2016, the Company implemented a restructuring plan. The restructuring plan resulted in: 1) reducing the Company’s workforce; 2) abandoning certain equipment; 3) cancelling certain contracts; 4) writing down inventory related to the SurgiBot System; and 5) writing off certain patents.

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 potentially wide range of clinical applications. Our strategy is to focus on the development and commercialization 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 September 30, 2017, we had an accumulated deficit of $371.5 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.

Recent Events

Debt Refinancing

On May 10, 2017, the Company and its domestic subsidiaries, as co-borrowers, entered into a Loan and Security Agreement (the “Innovatus Loan Agreement”) with Innovatus Life Sciences Lending Fund I, LP, as Lender and Collateral Agent (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, including Senhance Clearance (as defined below). 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 (“Senhance Clearance”) by May 30, 2018 (each such milestone, 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%) (the “Final Fee”); provided, however, that in the event the Company refinances its obligations with the Lender after Senhance Clearance, no Final Fee or Prepayment Fee (as defined below) will be due thereunder; 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 (the “Prepayment Fee”).

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 warrant issued in connection with funding of the first tranche entitles 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 least 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 (the “Underwriting Agreement”) with Stifel, Nicolaus & Company, Incorporated (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 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 first anniversary of the issuance date, unless terminated earlier as provided in the Series A Warrant. Receipt of Section 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 October 25, 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. As of October 25, 2017, Series B Warrants representing approximately 8.8 million shares had been exercised.

The exercise prices and the number of shares issuable upon exercise of each of the 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 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 prices of each of the Warrants. The exercisability of the Warrants may be limited if, upon exercise, the holder or any of its affiliates would beneficially own more than 4.99% of the Common Stock. If, at any time Warrants are outstanding, any fundamental transaction occurs, as described in the 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 Warrant holders. Additionally, in the event of a fundamental transaction, each Warrant holder will have the right to require the Company, or its successor, to repurchase the Warrants for an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of such 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 Warrants, after deducting underwriting discounts and commissions and estimated offering expenses paid by the Company.

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.

Lincoln Park Purchase Agreement

On December 16, 2016, we entered into a purchase agreement (the “LPC Purchase Agreement”) with Lincoln Park Capital Fund, LLC, an Illinois limited liability company (“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, the Company terminated the LPC Purchase Agreement. The LPC Purchase Agreement provided the Company with an election to terminate the Purchase Agreement for any reason or for no reason by delivering a notice to Lincoln Park, and the Company did not incur any early termination penalties in connection with the termination of the LPC Purchase Agreement. Prior to termination, the Company sold shares of its Common Stock to Lincoln Park under the LPC Purchase Agreement for gross proceeds of approximately $5.7 million.

Controlled Equity Offering

On February 9, 2016, we entered into a Controlled Equity Offering SM Sales Agreement (the “2016 Sales Agreement”) with Cantor Fitzgerald & Co. (“Cantor”) under which we can offer and sell, through Cantor, up to approximately $43.6 million in shares of common stock in an at-the market offering (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 (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 (the “2015 ATM Offering”). All sales of shares were made pursuant to an effective shelf registration statement on Form S-3 filed with the SEC. We pay 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 (the “2017 Sales Agreement”) with Stifel, Nicolaus & Company, Incorporated (“Stifel”) under which we can offer and sell, through Stifel, up to approximately $50.0 million in shares of common stock in an at-the-market offering (the “2017 ATM Offering”). All sales of shares were made pursuant to an effective shelf registration statement on Form S-3 filed with the SEC. We pay 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

Amendment to Membership Interest Purchase Agreement

On September 21, 2015, the Company announced that it had entered into a Membership Interest Purchase Agreement, dated September 18, 2015 (the “Purchase Agreement”) with Sofar S.p.A., (the “Seller”), Vulcanos S.r.l., as the acquired company, and TransEnterix International, Inc., a wholly owned subsidiary of the Company (the “Buyer”). The closing of the transactions contemplated by the Purchase Agreement occurred on September 21, 2015 (the “Closing Date”) pursuant to which 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 (“TransEnterix Italia”). 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 (the “Senhance Acquisition”).

Under the terms of the Purchase Agreement, the consideration consisted of the issuance of 15,543,413 shares of the Company’s common stock (the “Securities Consideration”) and approximately $25,000,000 U.S. Dollars and €27,500,000 Euro in cash consideration (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 entered into an amendment to restructure the terms of the Second Tranche of the Cash Consideration (the “Amendment”). 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.

34

The issuance of the Securities Consideration was effected as a private placement of securities under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), and Regulation D promulgated thereunder.

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.  

Results of Operations    

Revenue

Our revenue consisted of product and service revenue resulting from the sale in Europe and Asia of Senhance Systems, instruments and accessories, and related services. 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. Amounts billed in excess of the associated revenue recognized are deferred.

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 three months ended September 30, 2017 decreased to $0.2 million compared to $1.5 million for the three months ended September 30, 2016. The $1.3 million decrease was primarily the result of the revenue recognized on the sale of one Senhance System in the third quarter of 2016.

Product and service revenue for the nine months ended September 30, 2017 increased to $3.7 million compared to $1.5 million for the nine months ended September 30, 2016. The $2.2 million increase was primarily the result of the revenue recognized on the sale of two Senhance Systems during 2017.

Cost of Revenue

Cost of revenue consists primarily of costs related to contract manufacturing, materials, manufacturing overhead and field service costs. We expense all inventory provisions as cost of revenue. 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 revenue 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 three months ended September 30, 2017 decreased to $0.9 million as compared to $1.0 million for the three months ended September 30, 2016. This $0.1 million decrease over the prior year period was the result of decreased sales offset by increased costs for manufacturing overhead.

Cost of revenue for the nine months ended September 30, 2017 increased to $3.2 million as compared to $1.0 for the nine months ended September 30, 2016. This $2.2 million increase over the prior year period was the result of the costs recognized in connection with the sale of two Senhance Systems during 2017 compared to the sale of one Senhance System during 2016 and increased costs for manufacturing overhead.

35

Research and Development

Research and development (“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 three months ended September 30, 2017 decreased 30% to $4.9 million as compared to $7.0 million for the three months ended September 30, 2016. The $2.1 million decrease resulted primarily from decreased contract engineering services, consulting and other outside services of $2.2 million, decreased depreciation of $0.4 million and decreased facility costs of $0.5 million, and decreased other costs of $0.3 million, offset by increased supplies expense of $1.2 million.

R&D expenses for the nine months ended September 30, 2017 decreased 23% to $16.8 million as compared to $21.8 million for the nine months ended September 30, 2016. The $5.0 million decrease resulted primarily from the Company’s decision in 2016 to focus our resources solely on advancing the Senhance platform, resulting in decreased contract engineering services, consulting and other outside services of $2.4 million, decreased personnel related costs of $1.1 million, decreased facility costs of $0.8 million and decreased depreciation of $0.7 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 2017 in support of our Senhance System product launch. We cannot assure you that we will meet our anticipated product launch target for the Senhance System in 2017.

Sales and marketing expenses for the three months ended September 30, 2017 increased 73% to $4.5 million compared to $2.6 million for the three months ended September 30, 2016. The $1.9 million increase was primarily related to increased contract sales force costs of $0.6 million, increased personnel related costs of $0.5 million, increased travel related expenses of $0.5 million and increased other costs of $0.3 million.

Sales and marketing expenses for the nine months ended September 30, 2017 increased 114% to $12.0 million compared to $5.6 million for the nine months ended September 30, 2016. The $6.4 million increase was primarily related to increased personnel related costs of $2.1 million, increased travel related expenses of $0.9 million, increased depreciation expense $0.7 million, increased tradeshow costs of $0.6 million, increased contract sales force costs of $0.6 million, increased demonstration product costs of $0.5 million, increased stock compensation costs of $0.4 million and increased other costs of $0.6 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 three months ended September 30, 2017 of $2.9 million were consistent with general and administrative expenses of $2.8 million for the three months ended September 30, 2016.

General and administrative expenses for the nine months ended September 30, 2017 increased 10% to $8.7 million compared to $7.9 million for the nine months ended September 30, 2016. The $0.8 million increase was primarily due to increased stock compensation costs of $0.5 million and increased personnel costs of $0.5 million, offset by decreased other expenses of $0.2 million.

Amortization of Intangible Assets

Amortization of intangible assets for the three months ended September 30, 2017 increased to $1.8 million compared to $1.7 million for the three months ended September 30, 2016. The $0.1 million increase was primarily the result of the acquisition of patents.

Amortization of intangible assets for the nine months ended September 30, 2017 decreased to $5.1 million compared to $5.3 million for the nine months ended September 30, 2016. The $0.2 million decrease was primarily the result of the write-off of certain patents in May 2016.

36

Change in Fair Value of Contingent Consideration

The change in fair value of contingent consideration in connection with the Senhance Acquisition was $0.8 million for the three months ended September 30, 2017 and $(0.1) million for the three months ended September 30, 2016.  The increase of $0.9 million is primarily related to the effect of the change in discount rate, 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 $1.2 million for the nine months ended September 30, 2017 and $1.7 million for the nine months ended September 30, 2016.  The decrease of $0.5 million is primarily related to the change in the discount rate, passage of time on the fair value measurement and the impact of foreign currency exchange rates.

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 $22.9 million and $25.2 million for the three and nine months ended September 30, 2017, respectively. The increase was primarily the result of our increased stock price at September 30, 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 during the nine month periods ended September 30, 2016.

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.  

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.

Other Expense, Net

Other expense is primarily composed of interest expense on notes payable.

Other expenses for the three months ended September 30, 2017 increased to $0.7 million compared to $0.5 million for the three months ended September 30, 2016. The $0.2 million increase was primarily the result of the loss on the extinguishment of debt and increased interest expense.

Other expense for the nine months ended September 30, 2017 increased to $1.8 million compared to $1.4 million for the nine months ended September 30, 2016. The $0.4 million increase was primarily the result of the loss on the extinguishment of debt and increased interest expense.

37

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 $0.7 million and $1.1 million of income tax benefit for the three months ended September 30, 2017 and 2016, respectively. We recognized $2.3 million and $4.7 million of income tax benefit for the nine months ended September 30, 2017 and 2016, respectively. The Company estimates an annual effective tax rate of 4.1% for the year ending December 31, 2017. The primary difference between the estimated rate of 4.1% and the federal statutory rate of 34% is that a full valuation allowance has been recorded related to the net deferred tax assets in the US, Luxembourg, and Swiss jurisdictions, as well as the lower statutory tax rate in Italy. There is no net deferred tax asset recorded in relation to TransEnterix Italia and accordingly no valuation allowance has been recorded in that jurisdiction.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception we have incurred significant losses and, as of September 30, 2017, we had an accumulated deficit of $371.5 million. We have not yet achieved profitability and we cannot assure investors that we will achieve profitability with our existing capital resources. 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.

As of September 30, 2017, the Company had 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 October 31, 2017, we had $100.0 million available for future financings under such shelf registration statement.  

At October 31, 2017, we had cash, cash equivalents and restricted cash of approximately $100.6 million.
