Income Tax Disclosure [Text Block] |
12. Income Taxes
The components for the income tax expense are as follows for the years ended December 31 (in thousands):
The United States and foreign components of loss from operations before taxes are as follows for the years ended December 31 (in thousands):
Significant components of the Company’s deferred tax assets consist of the following at December 31 (in thousands):
At December 31, 2023 and 2022, the Company has provided a full valuation allowance against its net deferred assets in the U.S., Canada, Italy, Luxembourg, Switzerland, and Taiwan tax jurisdictions, since realization of these benefits is not more likely than not. The valuation allowance increased approximately $15.8 million from the prior year. At December 31, 2023, the Company had U.S. federal net operating loss carryforwards of $446.7 million, of which $253 million are expected to expire unused under the limitations imposed by Internal Revenue Code Section 382. Of the total amount of Federal NOLs (notwithstanding the 382 limitation), $254.5 million begin to expire in 2027, while the remaining $192.2 million carry forward indefinitely. At December 31, 2023, the Company had U.S. state net operating loss carryforwards of $336.3 million, of which $199 million are expected to expire unused under the state tax law equivalents of Internal Revenue Code Section 382. Of this amount (notwithstanding the 382 limitations), $323.0 million of state NOLs begin to expire in 2024, while the remaining $13.3 million carry forward indefinitely. At December 31, 2023, the Company had federal research credit carryforwards in the amount of $11.7 million. These carryforwards begin to expire in 2027. However, under the limitations of Internal Revenue Code Section 383, it is expected that $8.8 million of this carryforward will expire unused. The utilization of the federal net operating loss carryforwards and credit carryforwards will depend on the Company’s ability to generate sufficient taxable income prior to the expiration of the carryforwards.
At December 31, 2023, the Company had foreign operating loss carryforwards in Italy of approximately $25.0 million, which can be carried forward indefinitely; foreign operating loss carryforwards in Luxembourg of approximately $95.6 million, which will begin to expire in 2034; foreign operating loss carryforwards in Switzerland of approximately $135.3 million, which begin to expire in 2024, and foreign operating loss carryforwards in Canada of approximately $1.4 million, which begin to expire in 2040.
The Company has evaluated its tax positions to consider whether it has any unrecognized tax benefits. As of December 31, 2023, the Company had gross unrecognized tax benefits of approximately $0.7 million. Of the total, none would reduce the Company’s effective tax rate if recognized. The Company does not anticipate a significant change in total unrecognized tax benefits or the Company’s effective tax rate due to the settlement of audits or the expiration of statutes of limitations within the next twelve months. Furthermore, the Company does not expect any cash settlement with the taxing authorities as a result of these unrecognized tax benefits as the Company has sufficient unutilized carryforward attributes to offset the tax impact of these adjustments.
The following is a tabular reconciliation of the Company’s change in gross unrecognized tax positions at December 31 (in thousands):
The Company recognizes interest and penalties related to uncertain tax positions in the provision for income taxes. As of December 31, 2023 and 2022, the Company had no accrued interest or penalties related to uncertain tax positions.
The Company has analyzed its filing positions in all significant federal, state, and foreign jurisdictions where it is required to file income tax returns, as well as open tax years in these jurisdictions. With few exceptions, the Company is no longer subject to United States Federal, state, and local tax examinations by tax authorities for years before 2020, although carryforward attributes that were generated prior to 2020 may still be adjusted upon examination by the taxing authorities if they either have been or will be used in a future period. No income tax returns are currently under examination by taxing authorities.
Taxes computed at the then-current statutory federal income tax rate of 21% are reconciled to the provision for income taxes as follows for the years ended December 31:

13. Stock-Based Compensation
Incentive Compensation Plan Information
On June 6, 2023, at the 2023 Annual Meeting of Stockholders, the Company’s stockholders voted to approve an amendment and restatement of the Company’s Incentive Compensation Plan (“the Plan”) to increase the number of shares reserved for issuance under the Plan by 22,000,000 shares. As of December 31, 2023, there were 54,072,307 shares authorized for issuance, and 22,185,899 shares available for future issuance under the Plan. To date all equity awards under the Plan have consisted of nonqualified stock options, incentive stock options, restricted stock units and stock awards.
Under the Plan, which is administered by the Compensation Committee, the Company may grant stock options, stock appreciation rights, restricted stock units, restricted stock or stock awards to employees, officers, non-employee directors, consultants, and vendors. The exercise price of stock options or stock appreciation rights may not be less than the fair market value of the Company’s shares at the date of grant. Additionally, no stock options or stock appreciation rights granted under the Plan may have a term exceeding ten years.
Stock Options
The following table summarizes the Company’s stock option activity, including grants to non-employees, for the year ended December 31, 2023:
The weighted-average grant date fair value of stock options was $0.59 during the years ended December 31, 2023 and 2022. The aggregate intrinsic value of stock options exercised under the Company’s stock plans was not material during the years ended December 31, 2023 and 2022.
The following table summarizes information about stock options outstanding at December 31, 2023:
The fair value of options granted were estimated using the Black-Scholes-Merton option pricing model based on the assumptions in the table below:
Restricted Stock Units
The following is a summary of the restricted stock unit activity, including performance restricted stock units, for the year ended December 31, 2023:
Performance Restricted Stock Units
In 2023 and 2022, the Company granted performance-based restricted stock units (“PRSUs”). The number of shares earnable under the 2023 and 2022 awards were based on achieving certain operational targets by December 31, 2023 (for the PRSUs granted in 2023) and October 1, 2023 (for the PRSUs granted in 2022), respectively. In February 2024, the Board determined that the operational targets for PRSU awards granted in 2023 were 50% achieved and as a result, the 2023 PRSUs were 50% earned and remain subject to three-year time-based vesting requirements. The other 50% of the 2023 PRSUs were forfeited. The operational targets were achieved for the PRUSs granted in 2022, therefore the 2022 PRSUs were fully earned and remain subject to three-year time-based vesting requirements.
Stock-based Compensation Expense
The following table summarizes non-cash stock-based compensation expense by award type for the years ended December 31, 2023, and 2022:
As of December 31, 2023, the unrecognized stock-based compensation expense related to unvested stock options was approximately $1.6 million, which is expected to be recognized over an estimated weighted-average period of 1.4 years. As of December 31, 2023, the unrecognized stock-based compensation expense related to unvested restricted stock units and performance restricted stock units was approximately $4.4 million, which is expected to be recognized over a weighted average period of approximately 1.2 years. |

Significant Accounting Policies [Text Block] |
Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and include the accounts of the Company and its direct and indirect wholly owned subsidiaries.
Going Concern The Company's consolidated financial statements are prepared using U.S. GAAP applicable to a going concern, which contemplate the realization of assets and liquidation of liabilities in the normal course of business. The Company had an accumulated deficit of $939.4 million and working capital of $23.8 million as of December 31, 2023. The Company has not established sufficient sales revenues to cover its operating costs and requires additional capital to proceed with its operating plan. The ability of the Company to continue as a going concern is dependent on the Company obtaining adequate capital to fund operating losses until it becomes profitable.
The Company will need to obtain additional financing to proceed with its business plan. Management's plan to obtain additional resources for the Company may include additional sales of equity, traditional financing, such as loans, entry into a strategic collaboration, entry into an out-licensing arrangement or provision of additional distribution rights in some or all of our markets. However, management cannot provide any assurance that the Company will be successful in accomplishing any or all of its plans. The ability to successfully resolve these factors raise substantial doubt about the Company’s ability to meet its existing obligations, and to continue as a going concern within one year from the date that these financial statements are issued. The consolidated financial statements of the Company do not include any adjustments that may result from the outcome of these aforementioned uncertainties.
Principles of Consolidation and Foreign Currency Considerations The accompanying consolidated financial statements include the accounts of the Company and its direct and indirect wholly owned subsidiaries, Asensus Surgical US, Inc., Asensus International, Inc., Asensus Surgical Italia S.r.l., Asensus Surgical Europe S.à r.l., Asensus Surgical Taiwan Ltd., Asensus Surgical Japan K.K., Asensus Surgical Israel Ltd., Asensus Surgical Netherlands B.V., and Asensus Surgical Canada, Inc. All inter-company accounts and transactions have been eliminated in consolidation.
The functional currency of the Company’s operational foreign subsidiaries is predominantly the Euro. 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 loss as a separate component of stockholders’ equity which was $0.6 million and $1.9 million as of December 31, 2023 and 2022, respectively.
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 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 years ended December 31, 2023 and 2022 were not material.
Risk and Uncertainties The Company is subject to 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, obtain regulatory clearance for and commercialize its products and products in development; negative impacts on the Company's operations caused by the hostilities in the Middle East and other geopolitical factors; the success of its market development efforts; the timing and outcome of the regulatory review process for its products; changes in the healthcare regulatory environments of the United States, the European Union, Japan, Taiwan and other countries in which the Company operates or intends to operate; its ability to attract and retain key management, marketing and scientific personnel; 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 and digital surgical devices; and its ability to identify and pursue development of additional products.
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 impairment considerations for long-lived assets, fair value estimates related to contingent consideration, stock compensation expense, revenue recognition, short-term investments, changes in inventory reserves, inventory classification between current and non-current, measurement of lease liabilities and corresponding right-of-use (“ROU”) assets, and deferred tax asset valuation allowances.
Cash and Cash Equivalents, Restricted Cash, and Investments The Company considers all highly liquid investments with original maturities of 90 days or less at the time of purchase to be cash equivalents.
Restricted cash as of December 31, 2023 and 2022 includes $1.6 million and $1.1 million, respectively, in cash accounts held as collateral primarily under the terms of office operating leases, credit cards, and automobile leases, and a guarantee required by the government of a country for a 2019 VAT refund.
The Company’s investments as of December 31, 2023 consisted of corporate bonds that were classified as available-for-sale. Investments classified as available-for-sale are measured at fair value, and net unrealized gains and losses are recorded as a component of accumulated other comprehensive loss on the consolidated balance sheets until realized. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity computed under the effective interest method. Such amortization and accretion are included in interest expense, net. There were no gross realized gains or loss for the years ended December 31, 2023 and 2022.
Investments with remaining maturities at date of purchase greater than 90 days and remaining maturities as of the reporting period less than one year are classified as short-term investments. Investments with remaining maturities greater than one year are classified as long-term investments.
There have been no credit losses for the years ended December 31, 2023 and 2022, and no allowance for credit losses as of December 31, 2023 and 2022. Factors considered in determining whether a credit loss exists include credit ratings and other qualitative factors for each security type in the portfolio.
Fair Value Measurements The Company measures the fair value of money market funds, certain U.S. treasury securities, and equity investments with readily determinable value based on quoted prices in active markets for identical assets as Level 1 securities. Marketable securities measured at fair value using Level 2 inputs are primarily comprised of commercial paper and corporate notes and bonds without readily determinable value. The Company reviews trading activity and pricing for these investments as of the measurement date. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities obtained from various third-party data providers. These inputs either represent quoted prices for similar assets in active markets or have been derived from observable market data. This approach results in the Level 2 classification of these securities within the fair value hierarchy. The Company measures contingent consideration at fair value using a Monte-Carlo simulation utilizing Level 3 inputs. These inputs include the probability of achieving each of the potential milestones, revenue volatility, and an estimated discount rate associated with the risks of the expected cash flows attributable to the achievement of various milestones.
Concentrations and Credit Risk The Company’s principal financial instruments subject to potential concentration of credit risk are cash and cash equivalents (including restricted cash), and investments, including amounts held in money market funds, commercial paper, and corporate bonds. 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 domestic cash deposits may at times exceed the Federal Deposit Insurance Corporation’s 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. Investments are stated at their estimated fair values, based on quoted market prices for the same or similar instruments. The counterparties to the agreements relating to the Company’s investments consist of various major corporations, financial institutions, and government agencies of high credit standing.
The Company’s accounts receivable are derived from sales and leases to customers located throughout the world. The Company evaluates its customers’ financial condition and, generally, requires no collateral from its customers. The Company had one customer that accounted for 83% and 69% of the Company’s net accounts receivable as of December 31, 2023 and December 31, 2022, respectively. The Company had two customers that accounted for 33% and 19% of revenue in 2023, and one customer who accounted for 47% of revenue in 2022, respectively.
Accounts Receivable Accounts receivable are recorded at net realizable value, which includes an allowance for expected credit losses. The allowance for expected credit losses is based on the Company’s assessment of collectability of customer accounts. The Company regularly reviews the allowance by considering factors such as historical experience, credit quality, the age of the accounts receivable balances, and current and future economic conditions that may affect a customer’s ability to pay. The allowance for expected credit losses was $1.6 million as of December 31, 2023 and 2022.
Inventories Inventories are stated at the lower of cost (determined on a first-in, first-out basis) or 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 historical consumption and 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. The Company's classification of long-term inventory requires it to estimate the portion of on hand inventory that can be realized over the upcoming twelve months.
Definite-Lived Intangible Assets - Intellectual Property Intellectual property consists of purchased patent rights and developed technology acquired as part of a business acquisition. Developed technology includes reclassified in-process research and development (“IPR&D”) assets related to (i) the Senhance System acquired in 2015 and reclassified in 2017 and (ii) a 2018 acquisition and reclassified in 2020. 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.
The Company periodically evaluates intellectual property for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. To determine the recoverability, 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 assets, then such assets are written down to their fair value. No impairment of intellectual property was identified during the years ended December 31, 2023 and 2022.
Property and Equipment Property and equipment consists primarily of operating lease Senhance System assets, machinery, manufacturing equipment, demonstration equipment, computer equipment, furniture, and leasehold improvements, which are recorded at cost less accumulated depreciation. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets as follows:
The Company reviews its property and equipment 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.
During the years ended December 31, 2023 and 2022, the Company recorded a non-cash asset impairment charge of $0.4 million and $1.4 million, respectively, to reduce the carrying value of property and equipment to its estimated fair value. The property and equipment impairment is associated with returned Senhance Systems under operating leases and Senhance Systems currently under operating leases that are not expected to generate future cash flows sufficient to recover their net book value. The fair value was estimated based on the discounted cash flows expected to be produced by the property and equipment. The impairment was recorded in property and equipment impairment on the consolidated statements of operations and comprehensive loss.
Operating Leases The Company has operating leases for its corporate office buildings, vehicles, and machinery and equipment. At inception, the Company determines whether an agreement represents a lease, and at commencement, it evaluates each lease agreement to determine whether the lease constitutes an operating or financing lease.
The Company accounts for lease components and non-lease components as a single component. Non-lease components consist of common area maintenance payments for most real estate leases, which are determined based on costs incurred by the lessor. Many of the Company’s leases include base rental periods coupled with options to renew or terminate the lease, generally at the Company’s discretion. In evaluating the lease term, the Company considers whether renewal is reasonably certain. To the extent a significant economic incentive exists to renew the lease, the option is included within the lease term. Based on the Company’s leases, renewal options generally do not provide a significant economic incentive and are therefore excluded from the lease term. While its operating leases range from one year to ten years, some may include options to extend the lease generally between one year and six years, and some may include options to terminate the leases within one year.
The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes the appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Operating lease expense is recognized on a straight-line basis over the lease term, subject to any changes in the lease or expectations regarding the terms.
Implementation Costs in a Cloud Computing Arrangement The Company capitalizes qualified implementation costs incurred in a hosting arrangement that is a service contract. These capitalized implementation costs are recorded within other current and long-term assets, and are generally amortized over the fixed, non-cancellable term of the associated hosting arrangement on a straight-line basis and included within operating expenses.
Employee Retention Tax Credit Receivable The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) included an Employee Retention Tax Credit (“ERTC”) provision designed to encourage employers to keep employees on their payroll. The ERTC is a refundable tax credit against certain payroll taxes paid by employers for eligible wages. During the year ended December 31, 2021, the Company submitted an ERTC refund for $1.3 million and recorded the amount into Other Income (Expense) on the consolidated statements of operations and comprehensive loss. The Company received $0.7 million of the ERTC refund during the year ended December 31, 2022 and received the remaining $0.6 million during the year ended December 31, 2023.
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 Monte-Carlo simulation utilizing significant unobservable inputs including the probability of achieving each of the potential milestones, future Euro-to-USD exchange rates, revenue volatility 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 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.
On September 21, 2015, the Company completed the strategic acquisition, through its wholly owned subsidiary TransEnterix International, from Sofar S.p.A., an Italian company (“Sofar”), an Italian company, 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. Under the terms of the Purchase Agreement, as amended in 2016, as of December 31, 2023, the Company has accrued $2.2 million of estimated fair value of remaining contingent consideration related to a milestone of €15.0 million which 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 or in the event that (i) the Company or Asensus 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. In 2022, Sofar assigned its right to receive the contingent payment to Three Heads Investment S.r.l.
Warrant Liabilities The Company’s warrants (see “Note 14 – Equity Offerings,”) are measured at fair value using a Black-Scholes-Merton model option-pricing 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 stock price volatility, the expected dividend yield which is assumed to be zero since The Company has not paid and does not anticipate paying cash dividends on its shares of common stock and the risk-free interest rate is based on U.S. Treasury rates whose term is consistent with the term of the warrant (see “Note 6 – Fair Value,”). The warrant liability is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations and comprehensive loss.
Revenue Recognition The Company’s revenue consists of product revenue resulting from the sale of Senhance Systems, Senhance System components, and instruments and accessories. Service revenue consists of revenue related to Senhance System service agreements. Lease revenue consists of revenue generated from utilizing the Senhance System, instruments and accessories, and servicing of the Senhance System under operating lease agreements. The Company accounts for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. The Company's revenues are measured based on considerations specified in the contract with each customer, net of any sales incentives and taxes collected from customers that are remitted to government authorities. The Company’s Senhance System sale arrangements could include a five-year service period; the first year of service is generally free and included in the Senhance System sale arrangement with an option to purchase the remaining four years at a stated service price.
The Company’s Senhance System sale arrangements generally contain multiple products and services. For these consolidated sale arrangements, the Company accounts for individual products and services as separate performance obligations if they are distinct, which is if a product or service is separately identifiable from other items in the consolidated package, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company’s Senhance System sale arrangements may include a combination of the following performance obligations: system(s), system components, instruments, accessories, and system services.
For arrangements that contain multiple performance obligations, revenue is allocated to each performance obligation based on its relative estimated standalone selling price. When available, standalone selling prices are based on observable prices at which the Company separately sells the products or services.
The Company recognizes revenues when or as the performance obligations are satisfied by transferring control of the product or service to a customer. The Company generally recognizes revenue for the performance obligations as follows:
The Company invoices its customers based on the billing schedules in its sales arrangements. Payments are generally due 30 to 60 days from the date of invoice. Contract assets for the periods presented primarily represent the difference between the revenue that was recognized based on the relative selling price of the related performance obligations and the contractual billing terms in the arrangements and are included in accounts receivable.
In connection with assets recognized from the costs to obtain a contract with a customer, the Company determined that the sales incentive programs for its sales team do not meet the requirements to be capitalized as the Company does not expect to generate future economic benefits from the related revenue from the initial sales transaction and such costs are expensed as incurred.
Senhance System Leasing The Company enters into lease arrangements with certain qualified customers. Revenue related to arrangements including lease elements are allocated to lease and non-lease elements based on their relative standalone selling prices. Lease elements generally include a Senhance System, while non-lease elements generally include instruments, accessories, and services. For some lease arrangements, the customers are provided with the right to purchase the leased Senhance System at some point during and/or at the end of the lease term. In some arrangements lease payments are based on the usage of the Senhance System. For the years ended December 31, 2023 and 2022, variable lease revenue related to usage-based arrangements was not material.
In determining whether a transaction should be classified as a sales-type, operating, or direct financing lease, the Company considers the following terms at lease commencement: (1) whether title of the Senhance System transfers automatically or for a nominal fee by the end of the lease term, (2) whether the present value of the minimum lease payments equals or exceeds substantially all of the fair value of the leased Senhance System, (3) whether the lease term is for the major part of the remaining economic life of the leased System, (4) whether the lease grants the lessee an option to purchase the leased Senhance System that the lessee is reasonably certain to exercise, and (5) whether the underlying Senhance System is of such a specialized nature that it is expected to have no alternative use to the Company at the end of the lease term. All such arrangements through December 31, 2023 are classified as operating leases. Revenue related to lease elements from operating lease arrangements is generally recognized on a straight-line basis over the lease term or based upon Senhance System usage. As of December 31, 2023, future minimum lease payments due from customers was $2.2 million, which is expected to be received over the next one to two years.
Cost of Revenue Cost of revenue consists of contract manufacturing, materials, labor and manufacturing overhead incurred internally to produce the products. Depreciation expense related to leased systems is included in the cost of revenue. Shipping and handling costs incurred by the Company are included in the cost of revenue. We expense all inventory obsolescence provisions as cost of revenue.
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 recognizes expenses for share-based awards exchanged for services rendered equal to the estimated fair value of these awards over the requisite service period. The Company recognizes as expense, the grant-date fair value of stock options and other stock-based compensation issued to employees and non-employee directors over the requisite service periods, which are typically the vesting periods. The Company uses the Black-Scholes-Merton model to estimate the fair value of stock options. The volatility assumption used in the Black-Scholes-Merton model is based on the Company’s historical volatility. The expected term of options granted has been determined based upon the simplified method, because the Company does not have sufficient historical information regarding its options to derive the expected term. Under this approach, the expected term is the mid-point between the weighted average of vesting period and the contractual term. The risk-free interest rate is based on U.S. Treasury rates whose term is consistent with the expected life of the stock options. The Company has not paid and does not anticipate paying cash dividends on its shares of common stock; therefore, the expected dividend yield is assumed to be zero. The Company estimates forfeitures based on its historical experience and adjusts the estimated forfeiture rate based upon actual experience. For performance-based restricted stock awards with performance conditions, we begin recognizing compensation expense when it becomes probable that the performance condition will be attained.
The fair value of restricted stock units is determined by the market price of the Company’s common stock on the date of grant. See “Note 13 – Stock-Based Compensation,” for a detailed discussion of the Company’s stock plans and stock-based compensation expense.
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. The Company has elected to account for global intangible low-taxed income (“GILTI”) as a period expense in the year the tax is incurred.
The Company recognizes the financial statement benefit of an income tax position only after determining that the relevant taxing authority would more likely than not sustain the position following audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority. The Company recognizes interest accrued related to unrecognized tax benefits and penalties in the provision for income taxes.
Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require application of significant judgment. The Company is subject to U.S. federal and various state, local and foreign jurisdictions. Due to the Company’s net operating loss carryforwards, the Company may be subject to examination by authorities for all previously filed income tax returns.
Comprehensive Loss Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources.
Segments The Company operates in one business segment—the research, development and sale of medical device robotics to improve MIS. 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.
Impact of Recently Issued Accounting Standards In November 2023, the FASB issued Accounting Standards Update, or ASU, No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU looks to provide improvements to the segment disclosure by providing users with more decision-useful information about reportable segments in a public entity. The main provisions require a company to disclose, on an annual and interim basis, significant expenses included within each reported measure of segment profit or loss, an amount for other segment items by reportable segment and a description of its composition. It also requires all annual disclosures about a reportable segments’ profit or loss and assets to be reported on an interim basis.
The ASU is to be applied retrospectively to all prior periods presented in the financial statements with an effective date for all public entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this ASU.
In December 2023, the FASB issues ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU looks to enhance the transparency and decision usefulness of income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The main provisions to the rate reconciliation disclosure require public entities on an annual basis to: disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The main provisions to the income taxes paid disclosure require that all entities disclose on an annual basis: the amount of income taxes paid disaggregated by federal, state and foreign taxes and the amount of income taxes paid disaggregated by individual jurisdictions in which income taxes paid meets a quantitative threshold. This ASU also requires all entities to disclose: income (loss) from continuing operations before income tax expense (benefit) disaggregated between domestic and foreign and income tax expense (benefit) from continuing operations disaggregated by federal, state and foreign.
This ASU is to be applied on a prospective basis with an effective date for all public entities for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this ASU. |

Earnings Per Share [Text Block] |
15. 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 potential dilutive common shares that were outstanding during the period. Potential dilutive common shares consist of incremental shares issuable upon exercise of stock options, restricted stock units, and warrants. No adjustments have been made to the weighted average outstanding common shares figures for the years ended December 31, 2023 or 2022 as the assumed exercise of outstanding options, warrants and restricted stock units would be anti-dilutive.
Potential common shares not included in calculating diluted net loss per share are as follows:

14. Equity Offerings
Equity financing transactions for the years ended December 31, 2023 and 2022, include:
2022 At-The-Market Offering
On March 18, 2022, the Company entered into a Controlled Equity Offering Sales Agreement (the “2022 Sales Agreement”) with Cantor Fitzgerald & Co. and Oppenheimer & Co. Inc., collectively, “the Agents”. The Company commenced an at-the-market offering (the “2022 ATM Offering”) pursuant to which the Company could offer and sell, from time to time, at its option, shares of its common stock for an aggregate offering price of up to $100.0 million. The aggregate compensation payable to the Agents was 3.0% of the aggregate gross proceeds from each sale of the Company’s common stock. No shares were sold under the 2022 ATM Offering in 2022.
The following table presents details about common stock issued pursuant to the 2022 ATM Offering (in thousands, except share and per share amounts):
2023 Registered Equity Offering
On July 27, 2023, the Company sold, in a registered direct offering, an aggregate of 23,809,524 shares of common stock, and warrants to purchase 23,809,524 of the Company’s common stock shares at an exercise price of $0.42 per common share (the “warrants”), for an aggregate purchase price of $10.0 million. The warrants are exercisable at any time on or after the date of issuance and will expire five years after the date of issuance. Based on the assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480 – Distinguishing Liabilities from Equity and ASC 815 – Derivatives and Hedging, the Company determined that warrants did not meet the requirements for equity classification. Accordingly, the warrants were recorded as a liability on the Company’s balance sheet at their initial estimated fair value on the date of issuance. For additional information regarding the fair value of warrant liabilities, please refer to Note 4 – Fair Value Measurements.
The Company allocated $7.1 million of the aggregate proceeds to warrants based on their estimated fair value, with the residual amount of $2.9 million allocated to common stock. Offering related issuance costs were approximately $1.0 million and consisted primarily of placement agent’s fees and legal expenses. Issuance costs were allocated to common stock and warrant liability proportionally to the allocation of the purchase price. During the year ended December 31, 2023, the Company recorded $0.7 million of other expense, net, in the consolidated statement of operations related to issuance costs allocated to warrant liabilities. |

Fair Value Disclosures [Text Block] |
The following are categories of assets and liabilities measured at fair value on a recurring basis using quoted prices in active markets for identical assets (Level 1); significant other observable inputs (Level 2); and significant unobservable inputs (Level 3):
(1) Includes investments that are readily convertible to cash with original maturities of 90 days or less.
The carrying values of accounts receivable, prepaid expenses, employee retention tax credit receivables, other current assets, accounts payable, accrued employee compensation and benefits, accrued expenses, deferred revenue, and other current liabilities as of December 31, 2023 and December 31, 2022, approximate to their fair values due to the short-term nature of these items and are considered to be Level 1.
The Company’s financial liabilities consisted of contingent consideration payable to Three Heads Investment S.r.l., related to the Company’s 2015 acquisition of the Senhance Surgical System from an assignor to Three Heads Investment S.r.l. (the “Senhance Acquisition”). Adjustments associated with the change in fair value of contingent consideration are 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 for contingent consideration utilizing a Monte-Carlo simulation as of December 31, 2023 and December 31, 2022:
The following table presents the long-term portion of the contingent consideration for the year ended December 31, 2023 and summarizes the change in fair value, as determined by Level 3 inputs for the contingent consideration for the year ended December 31, 2023 and 2022:
Warrant Liabilities
During 2023, the Company recorded warrant liabilities related to common stock warrants issued in the registered direct offering in July 2023 (for additional information about the offering, please refer to Note 14 -Equity Offerings).

Adjustments associated with changes in fair value of the warrant liabilities are included in the Company’s consolidated statements of operations and comprehensive loss. The following table summarizes changes in estimated fair value of the warrant liabilities for the warrants issued in July 2023 as of December 31, 2023:
The fair value of the warrant liabilities were estimated using the Black-Scholes option pricing model, which is based on unobservable inputs and is designated as Level 3 in the fair value hierarchy. The following table summarizes the assumptions used in determining fair value of warrant liabilities:

Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||
Basis of Accounting, Policy [Policy Text Block] |
Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and include the accounts of the Company and its direct and indirect wholly owned subsidiaries.
|
||||||||||||||||||||||||||||||||||||
Substantial Doubt about Going Concern [Policy Text Block] |
Going Concern The Company's consolidated financial statements are prepared using U.S. GAAP applicable to a going concern, which contemplate the realization of assets and liquidation of liabilities in the normal course of business. The Company had an accumulated deficit of $939.4 million and working capital of $23.8 million as of December 31, 2023. The Company has not established sufficient sales revenues to cover its operating costs and requires additional capital to proceed with its operating plan. The ability of the Company to continue as a going concern is dependent on the Company obtaining adequate capital to fund operating losses until it becomes profitable.
The Company will need to obtain additional financing to proceed with its business plan. Management's plan to obtain additional resources for the Company may include additional sales of equity, traditional financing, such as loans, entry into a strategic collaboration, entry into an out-licensing arrangement or provision of additional distribution rights in some or all of our markets. However, management cannot provide any assurance that the Company will be successful in accomplishing any or all of its plans. The ability to successfully resolve these factors raise substantial doubt about the Company’s ability to meet its existing obligations, and to continue as a going concern within one year from the date that these financial statements are issued. The consolidated financial statements of the Company do not include any adjustments that may result from the outcome of these aforementioned uncertainties.
|
||||||||||||||||||||||||||||||||||||
Consolidation, Policy [Policy Text Block] |
Principles of Consolidation and Foreign Currency Considerations The accompanying consolidated financial statements include the accounts of the Company and its direct and indirect wholly owned subsidiaries, Asensus Surgical US, Inc., Asensus International, Inc., Asensus Surgical Italia S.r.l., Asensus Surgical Europe S.à r.l., Asensus Surgical Taiwan Ltd., Asensus Surgical Japan K.K., Asensus Surgical Israel Ltd., Asensus Surgical Netherlands B.V., and Asensus Surgical Canada, Inc. All inter-company accounts and transactions have been eliminated in consolidation.
The functional currency of the Company’s operational foreign subsidiaries is predominantly the Euro. 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 loss as a separate component of stockholders’ equity which was $0.6 million and $1.9 million as of December 31, 2023 and 2022, respectively.
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 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 years ended December 31, 2023 and 2022 were not material.
|
||||||||||||||||||||||||||||||||||||
Risk And Uncertainties, Policy [Policy Text Block] |
Risk and Uncertainties The Company is subject to 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, obtain regulatory clearance for and commercialize its products and products in development; negative impacts on the Company's operations caused by the hostilities in the Middle East and other geopolitical factors; the success of its market development efforts; the timing and outcome of the regulatory review process for its products; changes in the healthcare regulatory environments of the United States, the European Union, Japan, Taiwan and other countries in which the Company operates or intends to operate; its ability to attract and retain key management, marketing and scientific personnel; 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 and digital surgical devices; and its ability to identify and pursue development of additional products.
|
||||||||||||||||||||||||||||||||||||
Use of Estimates, Policy [Policy Text Block] |
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 impairment considerations for long-lived assets, fair value estimates related to contingent consideration, stock compensation expense, revenue recognition, short-term investments, changes in inventory reserves, inventory classification between current and non-current, measurement of lease liabilities and corresponding right-of-use (“ROU”) assets, and deferred tax asset valuation allowances.
|
||||||||||||||||||||||||||||||||||||
Cash and Cash Equivalents, Restricted Cash, and Investments, Policy [Policy Text Block] |
Cash and Cash Equivalents, Restricted Cash, and Investments The Company considers all highly liquid investments with original maturities of 90 days or less at the time of purchase to be cash equivalents.
Restricted cash as of December 31, 2023 and 2022 includes $1.6 million and $1.1 million, respectively, in cash accounts held as collateral primarily under the terms of office operating leases, credit cards, and automobile leases, and a guarantee required by the government of a country for a 2019 VAT refund.
The Company’s investments as of December 31, 2023 consisted of corporate bonds that were classified as available-for-sale. Investments classified as available-for-sale are measured at fair value, and net unrealized gains and losses are recorded as a component of accumulated other comprehensive loss on the consolidated balance sheets until realized. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity computed under the effective interest method. Such amortization and accretion are included in interest expense, net. There were no gross realized gains or loss for the years ended December 31, 2023 and 2022.
Investments with remaining maturities at date of purchase greater than 90 days and remaining maturities as of the reporting period less than one year are classified as short-term investments. Investments with remaining maturities greater than one year are classified as long-term investments.
There have been no credit losses for the years ended December 31, 2023 and 2022, and no allowance for credit losses as of December 31, 2023 and 2022. Factors considered in determining whether a credit loss exists include credit ratings and other qualitative factors for each security type in the portfolio.
|
||||||||||||||||||||||||||||||||||||
Fair Value Measurement, Policy [Policy Text Block] |
Fair Value Measurements The Company measures the fair value of money market funds, certain U.S. treasury securities, and equity investments with readily determinable value based on quoted prices in active markets for identical assets as Level 1 securities. Marketable securities measured at fair value using Level 2 inputs are primarily comprised of commercial paper and corporate notes and bonds without readily determinable value. The Company reviews trading activity and pricing for these investments as of the measurement date. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities obtained from various third-party data providers. These inputs either represent quoted prices for similar assets in active markets or have been derived from observable market data. This approach results in the Level 2 classification of these securities within the fair value hierarchy. The Company measures contingent consideration at fair value using a Monte-Carlo simulation utilizing Level 3 inputs. These inputs include the probability of achieving each of the potential milestones, revenue volatility, and an estimated discount rate associated with the risks of the expected cash flows attributable to the achievement of various milestones.
|
||||||||||||||||||||||||||||||||||||
Concentration Risk, Credit Risk, Policy [Policy Text Block] |
Concentrations and Credit Risk The Company’s principal financial instruments subject to potential concentration of credit risk are cash and cash equivalents (including restricted cash), and investments, including amounts held in money market funds, commercial paper, and corporate bonds. 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 domestic cash deposits may at times exceed the Federal Deposit Insurance Corporation’s 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. Investments are stated at their estimated fair values, based on quoted market prices for the same or similar instruments. The counterparties to the agreements relating to the Company’s investments consist of various major corporations, financial institutions, and government agencies of high credit standing.
The Company’s accounts receivable are derived from sales and leases to customers located throughout the world. The Company evaluates its customers’ financial condition and, generally, requires no collateral from its customers. The Company had one customer that accounted for 83% and 69% of the Company’s net accounts receivable as of December 31, 2023 and December 31, 2022, respectively. The Company had two customers that accounted for 33% and 19% of revenue in 2023, and one customer who accounted for 47% of revenue in 2022, respectively.
|
||||||||||||||||||||||||||||||||||||
Receivable [Policy Text Block] |
Accounts Receivable Accounts receivable are recorded at net realizable value, which includes an allowance for expected credit losses. The allowance for expected credit losses is based on the Company’s assessment of collectability of customer accounts. The Company regularly reviews the allowance by considering factors such as historical experience, credit quality, the age of the accounts receivable balances, and current and future economic conditions that may affect a customer’s ability to pay. The allowance for expected credit losses was $1.6 million as of December 31, 2023 and 2022.
|
||||||||||||||||||||||||||||||||||||
Inventory, Policy [Policy Text Block] |
Inventories Inventories are stated at the lower of cost (determined on a first-in, first-out basis) or 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 historical consumption and 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. The Company's classification of long-term inventory requires it to estimate the portion of on hand inventory that can be realized over the upcoming twelve months.
|
||||||||||||||||||||||||||||||||||||
Goodwill and Intangible Assets, Policy [Policy Text Block] |
Definite-Lived Intangible Assets - Intellectual Property Intellectual property consists of purchased patent rights and developed technology acquired as part of a business acquisition. Developed technology includes reclassified in-process research and development (“IPR&D”) assets related to (i) the Senhance System acquired in 2015 and reclassified in 2017 and (ii) a 2018 acquisition and reclassified in 2020. 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.
The Company periodically evaluates intellectual property for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. To determine the recoverability, 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 assets, then such assets are written down to their fair value. No impairment of intellectual property was identified during the years ended December 31, 2023 and 2022.
|
||||||||||||||||||||||||||||||||||||
Property, Plant and Equipment, Policy [Policy Text Block] |
Property and Equipment Property and equipment consists primarily of operating lease Senhance System assets, machinery, manufacturing equipment, demonstration equipment, computer equipment, furniture, and leasehold improvements, which are recorded at cost less accumulated depreciation. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets as follows:
The Company reviews its property and equipment 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.
During the years ended December 31, 2023 and 2022, the Company recorded a non-cash asset impairment charge of $0.4 million and $1.4 million, respectively, to reduce the carrying value of property and equipment to its estimated fair value. The property and equipment impairment is associated with returned Senhance Systems under operating leases and Senhance Systems currently under operating leases that are not expected to generate future cash flows sufficient to recover their net book value. The fair value was estimated based on the discounted cash flows expected to be produced by the property and equipment. The impairment was recorded in property and equipment impairment on the consolidated statements of operations and comprehensive loss.
|
||||||||||||||||||||||||||||||||||||
Lessee, Leases [Policy Text Block] |
Operating Leases The Company has operating leases for its corporate office buildings, vehicles, and machinery and equipment. At inception, the Company determines whether an agreement represents a lease, and at commencement, it evaluates each lease agreement to determine whether the lease constitutes an operating or financing lease.
The Company accounts for lease components and non-lease components as a single component. Non-lease components consist of common area maintenance payments for most real estate leases, which are determined based on costs incurred by the lessor. Many of the Company’s leases include base rental periods coupled with options to renew or terminate the lease, generally at the Company’s discretion. In evaluating the lease term, the Company considers whether renewal is reasonably certain. To the extent a significant economic incentive exists to renew the lease, the option is included within the lease term. Based on the Company’s leases, renewal options generally do not provide a significant economic incentive and are therefore excluded from the lease term. While its operating leases range from one year to ten years, some may include options to extend the lease generally between one year and six years, and some may include options to terminate the leases within one year.
The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes the appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Operating lease expense is recognized on a straight-line basis over the lease term, subject to any changes in the lease or expectations regarding the terms.
|
||||||||||||||||||||||||||||||||||||
Capitalization of Internal Costs, Policy [Policy Text Block] |
Implementation Costs in a Cloud Computing Arrangement The Company capitalizes qualified implementation costs incurred in a hosting arrangement that is a service contract. These capitalized implementation costs are recorded within other current and long-term assets, and are generally amortized over the fixed, non-cancellable term of the associated hosting arrangement on a straight-line basis and included within operating expenses.
|
||||||||||||||||||||||||||||||||||||
Employer Retention Tax Credit, Policy [Policy Text Block] |
Employee Retention Tax Credit Receivable The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) included an Employee Retention Tax Credit (“ERTC”) provision designed to encourage employers to keep employees on their payroll. The ERTC is a refundable tax credit against certain payroll taxes paid by employers for eligible wages. During the year ended December 31, 2021, the Company submitted an ERTC refund for $1.3 million and recorded the amount into Other Income (Expense) on the consolidated statements of operations and comprehensive loss. The Company received $0.7 million of the ERTC refund during the year ended December 31, 2022 and received the remaining $0.6 million during the year ended December 31, 2023.
|
||||||||||||||||||||||||||||||||||||
Contingent Consideration [Policy Text Block] |
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 Monte-Carlo simulation utilizing significant unobservable inputs including the probability of achieving each of the potential milestones, future Euro-to-USD exchange rates, revenue volatility 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 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.
On September 21, 2015, the Company completed the strategic acquisition, through its wholly owned subsidiary TransEnterix International, from Sofar S.p.A., an Italian company (“Sofar”), an Italian company, 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. Under the terms of the Purchase Agreement, as amended in 2016, as of December 31, 2023, the Company has accrued $2.2 million of estimated fair value of remaining contingent consideration related to a milestone of €15.0 million which 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 or in the event that (i) the Company or Asensus 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. In 2022, Sofar assigned its right to receive the contingent payment to Three Heads Investment S.r.l.
|
||||||||||||||||||||||||||||||||||||
Warrant Liabilities [Policy Text Block] |
Warrant Liabilities The Company’s warrants (see “Note 14 – Equity Offerings,”) are measured at fair value using a Black-Scholes-Merton model option-pricing 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 stock price volatility, the expected dividend yield which is assumed to be zero since The Company has not paid and does not anticipate paying cash dividends on its shares of common stock and the risk-free interest rate is based on U.S. Treasury rates whose term is consistent with the term of the warrant (see “Note 6 – Fair Value,”). The warrant liability is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations and comprehensive loss.
|
||||||||||||||||||||||||||||||||||||
Revenue [Policy Text Block] |
Revenue Recognition The Company’s revenue consists of product revenue resulting from the sale of Senhance Systems, Senhance System components, and instruments and accessories. Service revenue consists of revenue related to Senhance System service agreements. Lease revenue consists of revenue generated from utilizing the Senhance System, instruments and accessories, and servicing of the Senhance System under operating lease agreements. The Company accounts for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. The Company's revenues are measured based on considerations specified in the contract with each customer, net of any sales incentives and taxes collected from customers that are remitted to government authorities. The Company’s Senhance System sale arrangements could include a five-year service period; the first year of service is generally free and included in the Senhance System sale arrangement with an option to purchase the remaining four years at a stated service price.
The Company’s Senhance System sale arrangements generally contain multiple products and services. For these consolidated sale arrangements, the Company accounts for individual products and services as separate performance obligations if they are distinct, which is if a product or service is separately identifiable from other items in the consolidated package, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company’s Senhance System sale arrangements may include a combination of the following performance obligations: system(s), system components, instruments, accessories, and system services.
For arrangements that contain multiple performance obligations, revenue is allocated to each performance obligation based on its relative estimated standalone selling price. When available, standalone selling prices are based on observable prices at which the Company separately sells the products or services.
The Company recognizes revenues when or as the performance obligations are satisfied by transferring control of the product or service to a customer. The Company generally recognizes revenue for the performance obligations as follows:
The Company invoices its customers based on the billing schedules in its sales arrangements. Payments are generally due 30 to 60 days from the date of invoice. Contract assets for the periods presented primarily represent the difference between the revenue that was recognized based on the relative selling price of the related performance obligations and the contractual billing terms in the arrangements and are included in accounts receivable.
In connection with assets recognized from the costs to obtain a contract with a customer, the Company determined that the sales incentive programs for its sales team do not meet the requirements to be capitalized as the Company does not expect to generate future economic benefits from the related revenue from the initial sales transaction and such costs are expensed as incurred.

Lessor, Leases [Policy Text Block] |
Senhance System Leasing The Company enters into lease arrangements with certain qualified customers. Revenue related to arrangements including lease elements are allocated to lease and non-lease elements based on their relative standalone selling prices. Lease elements generally include a Senhance System, while non-lease elements generally include instruments, accessories, and services. For some lease arrangements, the customers are provided with the right to purchase the leased Senhance System at some point during and/or at the end of the lease term. In some arrangements lease payments are based on the usage of the Senhance System. For the years ended December 31, 2023 and 2022, variable lease revenue related to usage-based arrangements was not material.
In determining whether a transaction should be classified as a sales-type, operating, or direct financing lease, the Company considers the following terms at lease commencement: (1) whether title of the Senhance System transfers automatically or for a nominal fee by the end of the lease term, (2) whether the present value of the minimum lease payments equals or exceeds substantially all of the fair value of the leased Senhance System, (3) whether the lease term is for the major part of the remaining economic life of the leased System, (4) whether the lease grants the lessee an option to purchase the leased Senhance System that the lessee is reasonably certain to exercise, and (5) whether the underlying Senhance System is of such a specialized nature that it is expected to have no alternative use to the Company at the end of the lease term. All such arrangements through December 31, 2023 are classified as operating leases. Revenue related to lease elements from operating lease arrangements is generally recognized on a straight-line basis over the lease term or based upon Senhance System usage. As of December 31, 2023, future minimum lease payments due from customers was $2.2 million, which is expected to be received over the next one to two years.

Cost of Goods and Service [Policy Text Block] |
Cost of Revenue Cost of revenue consists of contract manufacturing, materials, labor and manufacturing overhead incurred internally to produce the products. Depreciation expense related to leased systems is included in the cost of revenue. Shipping and handling costs incurred by the Company are included in the cost of revenue. We expense all inventory obsolescence provisions as cost of revenue.

Research and Development Expense, Policy [Policy Text Block] |
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.

||||||||||||||||||||||||||||||||||||
Share-Based Payment Arrangement [Policy Text Block] |
Stock-Based Compensation The Company recognizes expenses for share-based awards exchanged for services rendered equal to the estimated fair value of these awards over the requisite service period. The Company recognizes as expense, the grant-date fair value of stock options and other stock-based compensation issued to employees and non-employee directors over the requisite service periods, which are typically the vesting periods. The Company uses the Black-Scholes-Merton model to estimate the fair value of stock options. The volatility assumption used in the Black-Scholes-Merton model is based on the Company’s historical volatility. The expected term of options granted has been determined based upon the simplified method, because the Company does not have sufficient historical information regarding its options to derive the expected term. Under this approach, the expected term is the mid-point between the weighted average of vesting period and the contractual term. The risk-free interest rate is based on U.S. Treasury rates whose term is consistent with the expected life of the stock options. The Company has not paid and does not anticipate paying cash dividends on its shares of common stock; therefore, the expected dividend yield is assumed to be zero. The Company estimates forfeitures based on its historical experience and adjusts the estimated forfeiture rate based upon actual experience. For performance-based restricted stock awards with performance conditions, we begin recognizing compensation expense when it becomes probable that the performance condition will be attained.
The fair value of restricted stock units is determined by the market price of the Company’s common stock on the date of grant. See “Note 13 – Stock-Based Compensation,” for a detailed discussion of the Company’s stock plans and stock-based compensation expense.

||||||||||||||||||||||||||||||||||||
Income Tax, Policy [Policy Text Block] |
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. The Company has elected to account for global intangible low-taxed income (“GILTI”) as a period expense in the year the tax is incurred.
The Company recognizes the financial statement benefit of an income tax position only after determining that the relevant taxing authority would more likely than not sustain the position following audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority. The Company recognizes interest accrued related to unrecognized tax benefits and penalties in the provision for income taxes.
Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require application of significant judgment. The Company is subject to U.S. federal and various state, local and foreign jurisdictions. Due to the Company’s net operating loss carryforwards, the Company may be subject to examination by authorities for all previously filed income tax returns.

Segment Reporting, Policy [Policy Text Block] |
Segments The Company operates in one business segment—the research, development and sale of medical device robotics to improve MIS. 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.

New Accounting Pronouncements, Policy [Policy Text Block] |
Impact of Recently Issued Accounting Standards In November 2023, the FASB issued Accounting Standards Update, or ASU, No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU looks to provide improvements to the segment disclosure by providing users with more decision-useful information about reportable segments in a public entity. The main provisions require a company to disclose, on an annual and interim basis, significant expenses included within each reported measure of segment profit or loss, an amount for other segment items by reportable segment and a description of its composition. It also requires all annual disclosures about a reportable segments’ profit or loss and assets to be reported on an interim basis.
The ASU is to be applied retrospectively to all prior periods presented in the financial statements with an effective date for all public entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this ASU.
In December 2023, the FASB issues ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU looks to enhance the transparency and decision usefulness of income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The main provisions to the rate reconciliation disclosure require public entities on an annual basis to: disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The main provisions to the income taxes paid disclosure require that all entities disclose on an annual basis: the amount of income taxes paid disaggregated by federal, state and foreign taxes and the amount of income taxes paid disaggregated by individual jurisdictions in which income taxes paid meets a quantitative threshold. This ASU also requires all entities to disclose: income (loss) from continuing operations before income tax expense (benefit) disaggregated between domestic and foreign and income tax expense (benefit) from continuing operations disaggregated by federal, state and foreign.
This ASU is to be applied on a prospective basis with an effective date for all public entities for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this ASU. |
