Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	1. Organization and Basis of Presentation Description of Business Sonendo, Inc. (the “Company” or “we” and “our”) was incorporated in June 2006 pursuant to the laws of the State of Delaware under the name Dentatek Corporation. In March 2011, the Company changed its name to Sonendo, Inc. The Company is a medical technology company that has developed and is commercializing the GentleWave System to treat tooth decay. The Company’s principal market is the United States (“U.S.”). The Company’s products include the GentleWave System, which is cleared by the U.S. Food and Drug Administration (the “FDA”) for sale in the U.S. and approved by Health Canada in Canada, along with the system’s sterilized, single-use procedure instruments (“PIs”). Basis of Presentation The Company’s financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to Form 10-Q and Article 10 of SEC Regulation S-X on a consistent basis with the Company’s annual financial statements and in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, considered necessary for a fair statement of the Company’s financial information. Accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. The condensed consolidated balance sheet as of December 31, 2023 included herein was derived from the audited financial statements as of that date. The results of operations included in these condensed consolidated financial statements are not necessarily indicative of the results of operations to be expected for the year, any other interim period, or for any other future annual or interim period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed, consolidated, or omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on March 11, 2024. As discussed in Note 3, “Discontinued Operations”, o n March 1, 2024, the Company divested its software segment by selling substantially all assets and liabilities of TDO Software, Inc, its wholly owned subsidiary. The sale met the criteria to be accounted for as a discontinued operation as required by Accounting Standards Codification (“ASC”) 205-20. Accordingly, the financial results of the software business are reported as discontinued operations in the accompanying unaudited Condensed C onsolidated Statements of Operations and Comprehensive Loss for all periods presented. The Company's Condensed Consolidated Statements of Cash Flows include the financial results of the software business for the three months ended March 31, 2024 and 2023. All amounts and disclosure included in the Notes to condensed consolidated financial statements reflect only the Company's continuing operations unless otherwise noted. Liquidity and Going Concern On September 27, 2022, the Company completed a private placement (the “Private Placement”), issuing an aggregate of approximately 23.0 million shares of its common stock at a purchase price of $ 0.95 per share and pre-funded warrants to purchase an aggregate of 43.3 million shares of common stock at a purchase price of $ 0.949 per pre-funded warrant. The pre-funded warrants have an exercise price of $ 0.001 per share of common stock, are immediately exercisable and will remain exercisable until exercised in full. The aggregate net proceeds from the Private Placement, after deducting placement agent fees and other offering expenses, were $ 59.0 million. See Note 6, Stockholders’ Equity, for additional information. As of March 31, 2024, the Company had cash and cash equivalents and short-term investments of $ 33.6 million and $ 23.2 million in principal outstanding under its term loan facility. The Company has a limited operating history, and the revenue and income potential of the Company’s business and market are unproven. The Company has experienced net losses and negative cash flows from operations since its inception and as of March 31, 2024 had an accumulated deficit of $ 436.8 million . During the three months ended March 31, 2024, the Company incurred net losses of $ 12.2 million , used $ 10.7 million of cash and cash equivalents in its continuing operations, and recognized a gain of $ 5.7 million from sale of discontinued operations. The Company will continue to incur significant costs and expenses related to its ongoing operations until it gains market acceptance of its products and achieves a level of revenues adequate to support its operations. The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty. The Company’s ability to continue as a going concern depends on its ability to continue to commercialize its products, achieve and maintain profitable operations, as well as the adherence to conditions of the outstanding term loan as amended in March 2024 (see Note 10). Without additional financing, the Company will have insufficient liquidity to achieve further commercialization of our products and maintain compliance with our loan covenants. Due to these conditions, there is substantial doubt about the Company’s ability to continue as a going concern and, therefore, it may be unable to realize its assets and discharge its liabilities in the normal course of business. The Company will require additional financing in order to fund its future expected negative cash flows. Due to its failure to comply with the continued listing standards set forth in the NYSE’s Listed Company Manual, our common stock was suspended from trading on the NYSE effective at the opening of business Eastern Standard Time on November 22, 2023. The Company commenced trading on the OTCQX on the same day. In April 2024, the Company withdrew its request to appeal and the NYSE and our common stock has been delisted from the NYSE, which may negatively impact the Company’s stockholders and the trading price and liquidity of its common stock. Over-the-counter markets are more limited than the NYSE, and it is likely that there will be significantly less liquidity in the trading of the Company’s common stock. The delisting of the Company’s common stock from the NYSE could have material adverse effects on its business, financial condition and results of operations. The Company has active plans to mitigate these conditions. Specifically, the Company has been taking steps and plans to further reduce negative cash flow through operating expense reductions. The Company is evaluating multiple opportunities, which may include soliciting external investment or seeking strategic partnerships. Additionally, as detailed in Note 3 and Note 10 , the Company closed on the sale of TDO Software, Inc. (“TDO”) and renegotiated its covenant requirements with its lender, among other terms, which resulted in the Company remitting $ 15 million of principal payments on its outstanding borrowings. Its plans are subject to inherent risks and uncertainties and there can be no assurance that its plans can be effectively implemented and, therefore, that the conditions can be effectively mitigated. Effects of the Macroeconomic Environment The Company’s unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2024 reflect the Company’s estimates of the impact of the macroeconomic environment, including the impact of inflation and higher interest rates. The duration and the scope of these conditions cannot be predicted; therefore, the extent to which these conditions will directly or indirectly impact the Company’s business, results of operations and financial condition, is uncertain. The Company is not aware of any specific event or circumstance that would require an update to its estimates, judgments and assumptions or a revision of the carrying value of the Company’s assets or liabilities as of the date of this filing. Operating Segments The Company previously had two operating and reportable segments: Product and Software. Following the divestiture of the software business on March 1, 2024, there were no substantial assets or operations of the software segment. The software segment was reported as Discontinued Operations as of March 31, 2024, and is presented as such for all periods in this report. Emerging Growth Company Status The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to avail itself of this exemption and, therefore, for new or revised accounting standards applicable to public companies, the Company will be subject to an extended transition period until those standards would otherwise apply to private companies.

Accounting Policies [Abstract]
Summary Accounting Policies and Recent Accounting Pronouncements	2. Summary Accounting Policies and Recent Accounting Pronouncements The accounting policies followed by the Company are set forth in Part II, Item 8, Note 2, Summary of Accounting Policies , of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make informed estimates, judgements and assumptions that affect the reported amounts in the unaudited condensed consolidated financial statements and disclosures in the accompanying notes, including estimates of probable losses and expenses, as of the date of the accompanying unaudited condensed consolidated financial statements. Management considers many factors in selecting appropriate financial accounting policies and in developing the estimates and assumptions that are used in the preparation of these unaudited condensed consolidated financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including the expected business and operational changes, the sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and management must select an amount that falls within that range of reasonable estimates. Actual results could differ materially from the estimates and assumptions used in the preparation of the accompanying unaudited condensed consolidated financial statements under different assumptions or conditions. Inventory Inventory consists of finished products, work-in-process and raw materials and is valued at the lower of cost or net realizable value. Cost may include materials, labor and manufacturing overhead. Cost is determined by the first in, first out inventory method. The carrying value of inventory is reviewed for potential impairment whenever indicators suggest that the cost of inventory exceeds the carrying value and management adjusts the inventory to its net realizable value. The Company also periodically evaluates inventory for estimated losses from excess quantities and obsolescence and writes down the cost of inventory to net realizable value at the time such determinations are made. Net realizable value is determined using the estimated selling price, in the ordinary course of business, less estimated costs of completion and disposal. Revenue Recognition Contracts with Customers The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods and services. Specifically, the Company applies the following five core principles to recognize revenue: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, the Company satisfies a performance obligation. Revenue recorded from continuing operations is generated from sales of the GentleWave Console and related PIs and accessories and services on its GentleWave Console. The Company’s products are sold primarily in the United States and Canada directly to customers through its field sales force. Performance Obligations The Company’s performance obligations from continuing operations primarily arise from the manufacture and delivery of the GentleWave System, related PIs and accessories, and to a lesser extent, performance of service contracts on its GentleWave Consoles. Payment terms are typically on open credit terms consistent with industry practice and do not have significant financing components. Consideration may be variable based on volume. The Company considers the individual deliverables in its product offering as separate performance obligations and assesses whether each promised good or service is distinct. The total contract transaction price is determined based on the consideration expected to be received, based on the stated value in contractual arrangements or the estimated cash to be collected in no-contracted arrangements, and is allocated to the identified performance obligations based upon the relative standalone selling prices of the performance obligations. The stand-alone selling price is based on an observable price offered to other comparable customers. The Company estimates the standalone selling price using the market assessment approach considering market conditions and entity-specific factors including, but not limited to, features and functionality of the products and services, geographies, type of customer and market conditions. The Company regularly reviews and updates standalone selling prices as necessary. The consideration the Company receives in exchange for its goods or services is only recognized when it is probable that a significant reversal will not occur. The consideration to which the Company expects to be entitled includes a stated list price, less various forms of variable consideration. The Company estimates related variable consideration at the point of sale, including discounts, product returns, refunds, and other similar obligations. Revenue is recognized over time when the customer simultaneously receives and consumes the benefits provided by the Company’s performance. Revenue is recognized at a point in time if the criteria for recognizing revenue over time are not met, and the Company has transferred control of the goods to the customer. Product revenue is recognized at a point in time when the Company has transferred control to the customer, which is generally when title of the goods transfers to the customer. Sales of extended service contracts are recorded as deferred revenue until such time as the standard warranty expires, which is generally up to two years from the date of sale. Service contract revenue is recognized on a straight-line basis over time consistent with the life of the related service contract in proportion to the costs incurred in fulfilling performance obligations under the service contract. The Company generally does not experience significant returns. If necessary, a provision is recorded for estimated sales returns and allowances and is deducted from gross product revenue to arrive at net product revenue in the period the related revenue is recorded. These estimates are based on historical sales returns and allowances and other known factors. Actual returns and claims in any future period are inherently uncertain and thus may differ from these estimates. If actual or expected future returns and claims are significantly greater or lower than the reserves established, a reduction or increase to revenue will be recorded in the period in which such a determination is made. All non-income government-assessed taxes (sales and use taxes) collected from the Company’s customers and remitted to governmental agencies are recorded in accrued expenses until they are remitted to the government agency. The Company has adopted the practical expedient permitting the direct expensing of costs incurred to obtain contracts where the amortization of such costs would occur over one year or less, and it applied to substantially all the Company’s contracts. Contract liabilities The Company recognizes a contract liability when a customer pays for goods or services for which the Company has not yet transferred control. The balances of the Company’s contract liabilities are as follows: March 31, December 31, 2024 2023 (in thousands) Total contract liabilities - extended service contracts $ 1,048 $ 920 Less: long-term portion 281 302 Contract liabilities – current $ 767 $ 618 Contract liabilities are included within other current liabilities and other long-term liabilities in the accompanying unaudited condensed consolidated balance sheets. Revenue recognized during the three months ended March 31, 2024 and 2023 that was included in the contract liability balance as of December 31, 2023 and 2022 was $ 0.2 million and $ 0.1 million, respectively. Disaggregation of revenue The Company disaggregates revenue from contracts with customers by segment and by the timing of when goods and services are transferred, which depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected. The following table provides information regarding disaggregated revenues and the timing of when goods and services are transferred: Three Months Ended March 31, 2024 2023 (in thousands) Product revenue recognized at a point in time $ 6,730 $ 8,524 Service revenue recognized over time 317 154 Total revenue $ 7,047 $ 8,678 No individual customer accounted for more than 10% of sales for the three months ended March 31, 2024 and 2023. Warranty Reserve The Company provides a standard warranty on its GentleWave Systems for a specified period of time. For the three months ended March 31, 2024 and 2023, GentleWave Systems sold were covered by the warranty for a period of up to two years from the date of sale. Estimated warranty costs are recorded as a liability at the time of delivery with a corresponding provision to cost of sales. Warranty accruals are estimated based on the current product costs, the Company’s historical experience, management’s expectations of future conditions and standard maintenance schedules. The Company evaluates this reserve on a regular basis and makes adjustments as necessary. The following table provides a reconciliation of the change in estimated warranty liabilities for the three months ended March 31, 2024 and 2023: Three Months Ended March 31, 2024 2023 (in thousands) Balance at beginning of period $ 1,269 $ 1,930 Provision for warranties issued 200 195 Warranty costs incurred ( 427 ) ( 368 ) Balance at end of period $ 1,042 $ 1,757 Current portion $ 980 $ 1,335 Non-current portion 62 422 Total $ 1,042 $ 1,757 The warranty liabilities, current and non-current, are included in other current liabilities and other liabilities, respectively, on the unaudited condensed consolidated balance sheets. Recent Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASU”). ASUs not listed below were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s unaudited condensed consolidated financial statements. Accounting Pronouncement Recently Adopted None.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	3. Discontinued Operations On March 1, 2024, the Company entered into an Asset Purchase Agreement by and among TDO, Valsoft Corporation Inc., a Quebec corporation, and Aspire USA LLC, a Delaware limited liability company and affiliate of Valsoft (collectively “Valsoft”), pursuant to which TDO agreed to sell to Valsoft substantially all the assets and liabilities relating to the Company’s software segment. As consideration for the transaction, Valsoft agreed to pay TDO approximately $ 16.0 million, with $ 15.0 million paid on March 1, 2024 and $ 1.0 million due in approximately 12 months. In connection with the transaction, Valsoft agreed to make offers of employment to certain employees of the Business on terms that are comparable to those currently in effect for such employees. The Asset Purchase Agreement contains certain representations, warranties and covenants of each of TDO and Valsoft. Each of TDO and the Valsoft has agreed to indemnify the other for certain losses arising out of breaches of representations and covenants and for certain losses arising out of retained liabilities or assumed liabilities relating to the TDO business, as applicable, subject to customary limitations. The divestiture met the criteria to be accounted for as a discontinued operation as of March 31, 2024. Accordingly, the operating results of the continued and discontinued operations for the three months ended March 31, 2024 are presented in the Condensed Consolidated Statements of Operations and Comprehensive Loss within income from discontinued operations as follows: Three Months Ended March 31, 2024 2023 (in thousands) Revenue $ 1,389 $ 2,046 Cost of sales 510 678 Gross profit 879 1,368 Operating expenses: Selling, general and administrative 679 552 Research and development 476 567 (Loss) income from discontinued operations, net of tax ( 276 ) 249 Other income — 22 Gain on sale of discontinued operations, net of tax 5,703 — Net income from discontinued operations $ 5,427 $ 271 Software is licensed via delivery to the customer or via a service arrangement under which cloud-based access is provided on a subscription basis (software-as-a-service).

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	. Fair Value of Financial Instruments The Company applies fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The Company’s financial instruments consist principally of cash, cash equivalents, short-term investments, accounts receivable, accounts payable, operating lease liabilities, warrant liabilities and a term loan. Fair value is measured as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market. Valuation techniques that are consistent with the market, income or cost approach are used to measure fair value. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels: Level 1 – Observable inputs such as unadjusted quoted prices in active markets that are accessible at the measurement date for identical unrestricted assets or liabilities the Company has the ability to access. Level 2 – Inputs (other than quoted prices included within Level 1) that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3 – Unobservable inputs that are significant to the fair value measurement and reflect the reporting entity’s use of significant management judgment and assumptions when there is little or no market data. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques and significant management judgment or estimation. These include the Black-Scholes option-pricing model which uses inputs such as expected volatility, risk-free interest rate and expected term to determine fair market valuation. Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification at each reporting date. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The Company did not have any transfers of assets and liabilities between the levels of the fair value measurement hierarchy during the periods presented. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, and certain accrued expenses approximate fair value due to the short-term nature of these items. Accordingly, the Company estimates that the recorded amounts approximate fair market value. The following table provides the assets and liabilities measured at fair value on a recurring basis and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such value at March 31, 2024 and December 31, 2023: March 31, 2024 Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) Assets: Cash equivalents: Money market funds $ 17,671 $ 17,671 $ — $ — Total cash equivalents at fair value 17,671 17,671 — — Short-term investments: U.S. treasury securities 5,697 5,697 — — Commercial paper and corporate bonds 9,312 — 9,312 — Total short-term investments at fair value 15,009 5,697 9,312 — Total assets at fair value $ 32,680 $ 23,368 $ 9,312 $ — March 31, 2024 Fair Cost Amounts Recognized in Accumulated Other Comprehensive Loss Unrealized Gains Unrealized Losses (in thousands) Available-for-sale securities: U.S. treasury securities $ 5,697 $ 5,697 $ — $ — Commercial paper and corporate bonds $ 9,312 9,313 1 ( 2 ) Total available-for-sale securities at fair value $ 15,009 $ 15,010 $ 1 $ ( 2 ) December 31, 2023 Fair Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) Assets: Cash equivalents: Money market funds $ 10,761 $ 10,761 $ — $ — Corporate Bonds 1,827 — 1,827 — Total cash equivalents at fair value 12,588 10,761 1,827 — Short-term investments: U.S. treasury securities 14,826 14,826 — — Commercial paper and corporate bonds 13,204 — 13,204 — U.S. government agency bonds 4,743 — 4,743 — Total short-term investments at fair value 32,773 14,826 17,947 — Total assets at fair value $ 45,361 $ 25,587 $ 19,774 $ — December 31, 2023 Fair Cost Amounts Recognized in Accumulated Other Comprehensive Loss Unrealized Gains Unrealized Losses (in thousands) Available-for-sale securities: U.S. Treasury securities $ 14,826 $ 14,820 $ 6 $ — Commercial paper and corporate bonds $ 13,204 $ 13,197 $ 9 $ ( 2 ) U.S. government agency bonds 4,743 4,745 — ( 2 ) Total available-for-sale securities at fair value $ 32,773 $ 32,762 $ 15 $ ( 4 ) Money market funds and U.S. Treasury securities are highly liquid investments and are actively traded. The pricing information on these investment instruments is readily available and can be independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy. Commercial paper, U.S. government agency bonds and corporate bonds are measured at fair value using Level 2 inputs. The Company reviews trading activity and pricing for these investments as of each 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 third party data providers. These inputs represent quoted prices for similar assets in active markets or these inputs have been derived from observable market data. This approach results in the classification of these securities as Level 2 of the fair value hierarchy.

Equity [Abstract]
Stockholders' Equity	6. Stockholders’ Equity Warrants In April 2022, the Company amended its term loan and the warrants previously issued to Perceptive Credit Holdings III, LP (“Perceptive”) and certain of its affiliates to purchase an aggregate of 304,105 shares of its common stock. Such warrants were amended solely to reduce the exercise price of the warrants to $ 12.00 per share. Warrants issued and outstanding at March 31, 2024 and December 31, 2023 included 19,179 warrants with exercise price of $ 10.95 per share and 304,105 warrants with exercise price of $ 12.00 per share in each period. These warrants expire between June 2024 and August 2031 . On September 27, 2022, the Company completed the Private Placement, issuing an aggregate of approximately 23.0 million shares of its common stock at a purchase price of $ 0.95 per share and pre-funded warrants to purchase an aggregate of 43.3 million shares of common stock at a purchase price of $ 0.949 per pre-funded warrant to certain institutional investors and accredited investors (the “Purchasers”). The pre-funded warrants have an exercise price of $ 0.001 per share of common stock, are immediately exercisable and will remain exercisable until exercised in full. The aggregate net proceeds from the Private Placement, after deducting placement agent fees and other offering expenses, were $ 59.0 million. The pre-funded warrants include a provision whereby the exercisability of the warrants may be limited if, upon exercise, the warrant holder or any of its affiliates would beneficially own more than 9.99 % of the Company’s common stock. The threshold is subject to the Purchasers’ rights under the pre-funded warrant to increase or decrease such percentage to any other percentage not in excess of 19.99 % upon at least 61 days’ prior notice from the Purchasers to the Company. As of March 31, 2024, approximately 6.1 million shares have been issued pursuant to the exercise of pre-funded warrants and 24.9 million shares underlying the pre-funded warrants remain outstanding. The pre-funded warrants are classified as equity and are accounted for as a component of additional paid-in capital at the time of issuance. The pre-funded warrants are included in the calculation of basic and diluted loss per share. Pursuant to the terms and conditions of the purchase agreements entered into by the Purchasers, the Company was obligated to file a registration statement with the SEC registering the resale by the Purchasers of the shares of common stock issued to them in the Private Placement and the shares of common stock to be issued to them upon exercise of the pre-funded warrants issued to them in the Private Placement within 45 days of the closing of the Private Placement. On November 4, 2022, the Company filed a registration statement on Form S-3 (File No. 333-268174), as required under the purchase agreements, and the registration statement was declared effective by the SEC on November 16, 2022.

Leases [Abstract]
Leases	8. Leases The Company leases office space under operating leases with expirations ranging from March 2025 to March 2028, some of which include rent escalations or an option to extend the lease for up to three years per renewal. The exercise of lease renewal options is at the sole discretion of the Company. As of March 31, 2024 , the Company has not entered into any new leases that would entitle the Company to significant rights or create additional obligations. The Company determines whether a contract is or contains a lease at the inception of the contract. A contract will be deemed to be or contain a lease if the contract conveys the right to control and direct the use of identified property, plant, or equipment for a period of time in exchange for consideration. The Company generally must also have the right to obtain substantially all of the economic benefits from the use of the property, plant, and equipment. The Company has elected the practical expedient to not separate its lease component from non-lease component for its real estate leases. The Company has elected the practical expedient not to apply the lease recognition requirements to short-term leases with an initial term of 12 months or less. The Company uses either its incremental borrowing rate or the implicit rate in the lease agreement as the basis to calculate the present value of future lease payments at lease commencement. The incremental borrowing rate represents the rate the Company would have to pay to borrow funds on a collateralized basis over a similar term and in a similar economic environment. Future minimum lease payments under these leases are as follows: Lease Amounts (in thousands) 2024 (remaining nine months) $ 937 2025 1,008 2026 892 2027 480 2028 122 Total future minimum lease payments 3,439 Less: Imputed Interest ( 379 ) Present value of operating lease liabilities $ 3,060 Less: Current portion 1,172 Long-term operating lease liabilities $ 1,888 Weighted average remaining lease term in years 3.08 Weighted average discount rate 8.24 % Variable operating lease expenses consist primarily of real estate taxes and insurance. The components of lease expense and related cash flows were as follows: Three Months Ended March 31, 2024 2023 (in thousands) Rent expense $ 356 $ 386 Variable lease costs — 32 Total $ 356 $ 418 Cash paid for operating leases $ 370 $ 376 Three Months Ended March 31, 2024 2023 (in thousands) Cost of sales $ 80 $ 70 Selling, general and administrative 276 348 Total $ 356 $ 418

Debt Disclosure [Abstract]
Term Loan	. Term Loan Perceptive loan On January 13, 2023, the Company entered into Amendment No. 2 (the “Second Amendment”) to the Amended and Restated Credit Agreement and Guaranty by and among the Company, the Subsidiary Guarantors party thereto, the Lenders party thereto and Perceptive (the “Amended Perceptive Loan Agreement”) to replace the existing benchmark rate from the one-month LIBOR with a one-month Secured Overnight Financing Rate (“SOFR”). All other terms remain unchanged on the original agreement. For the three months ended March 31, 2024 and 2023 , the interest rate for amounts borrowed under the Amended Perceptive Loan Agreement was the greater of the one-month SOFR and 2.00 % plus the applicable margin of 9.25 %. On March 1, 2024, the Company entered into Amendment No. 3 (the “Third Amendment”) to the Amended Perceptive Loan Agreement. Pursuant to the Third Amendment, the Company made a one-time $ 15.0 million principal repayment on March 1, 2024, and agreed to make an amortization payment of $ 1.8 million on the outstanding principal on March 31, 2024 and make monthly amortization payments on the outstanding principal each in the amount of $ 0.9 million on each payment date commencing on April 30, 2024 . Accordingly, $ 1.0 million of the unamortized debt issuance costs were expensed. For the three months ended March 31, 2024 and 2023, the effective interest rate of the Amended Perceptive Loan, was 21.22 % and 16.71 %, respectively. As of March 31, 2024 and 2023, the fair value of the Amended Perceptive Loan approximates its carrying amount. Pursuant to the Third Amendment, future principal repayments and the net carrying value of the Perceptive Loan as of March 31, 2024, are as follows: Principal (in thousands) Remaining 9 months of 2024 $ 8,100 2025 10,800 2026 4,300 Total principal payment 23,200 Debt discounts ( 1,489 ) Net carrying value $ 21,711 The Company is permitted to make voluntary prepayments, subject to a scaled prepayment premium that ranges from 7.0 % to 1.0 % of the aggregate principal amount outstanding on such prepayment date for prepayments made after August 23, 2022 and before August 23, 2025. No prepayment premium is required for payments made after August 23, 2025. The Amended Perceptive Loan Agreement contains events of default, including, without limitation, upon: (i) failure to make a payment pursuant to the terms of the agreement; (ii) violation of certain covenants; (iii) payment or other defaults on other indebtedness; (iv) material adverse change in the business or change in control; (v) insolvency; (vi) significant judgments; (vii) incorrectness of representations and warranties; (viii) regulatory matters; and (ix) failure by us to maintain a valid and perfected lien on the collateral securing the borrowing. Based on the Amended Perceptive Loan Agreement, the Company has granted a security interest in substantially all of its assets. The Amended Perceptive Loan Agreement includes financial covenants that require the Company to (i) maintain, at all times, a minimum aggregate balance of $ 3.0 million in cash in one or more controlled accounts, and (ii) pursuant to the Third Amendment, satisfy certain minimum revenue thresholds, measured for the consecutive 12-month periods ending on each calendar quarter-end until June 30, 2026 as follows: For 12-month Period Ending Revenue (in thousands) March 31, 2024 $ 39,000 June 30, 2024 $ 35,500 September 30, 2024 $ 33,000 December 31, 2024 $ 31,500 March 31, 2025 $ 31,000 June 30, 2025 $ 33,000 September 30, 2025 $ 35,935 December 31, 2025 $ 40,160 March 31, 2026 $ 44,950 June 30, 2026 $ 51,500 Pursuant to the Third Amendment, the lender also waived the covenant requiring the absence of any “going concern” or like qualification or exception or any qualification or exception as to the scope of the audit, solely with respect to the fiscal year ending on December 31, 2023 . Failure to satisfy any covenants would constitute an event of default under the Amended Perceptive Loan Agreement. In the event of an event of default, the lender may terminate its commitments and declare all amounts outstanding under the Amended Perceptive Loan Agreement immediately due and payable, together with accrued interest and all fees and other obligations. The amount of such repayment will include payment of any prepayment premium applicable due to the time of such payment. In addition, upon the occurrence and during the continuance of any event of default, the applicable margin will increase by 3.00 % per annum to 12.25 %. Total revenue generated from continuing and discontinued operations for the 12-months period ended March 31, 2024 was $ 41.6 million, and cash and cash equivalents and short term investment balance was $ 33.6 million as of March 31, 2024. As such, the Company was in compliance with all financial covenants and conditions under the Amended Perceptive Loan Agreement as of March 31, 2024.

Income Taxes	11. Income Taxes The Company maintains a full valuation allowance against its net deferred tax assets as of March 31, 2024 based on the current assessment that it is not more likely than not these future benefits will be realized before expiration. No material income tax expense or benefit has been recorded given the valuation allowance position and projected taxable losses in the jurisdictions where the Company files income tax returns. The Company has not experienced any significant increases or decreases to its unrecognized tax benefits since December 31, 2023 and does not expect any within the next 12 months. The Company monitors changes to the tax laws in the states it conducts business and files corporate income tax returns. Utilization of the net operating loss carryforwards may be subject to substantial annual limitation due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as similar state provisions. These ownership changes may limit the amount of net operating loss carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the outstanding stock of a company by certain stockholders or public groups. The Company has not completed an analysis regarding the limitation of net operating loss and R&D credit carryforwards as of March 31, 2024. The Company is subject to U.S. federal and various states income taxes. The federal returns for tax y ears 2021 through 2023 remain open to examination and the state returns remain subject to examination for tax years 2020 through 2023 . Carryforward attributes that were generated in years where the statute of limitations is closed may still be adjusted upon examination by the Internal Revenue Service or other respective tax authorities. All other state jurisdictions remain open to examination.

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make informed estimates, judgements and assumptions that affect the reported amounts in the unaudited condensed consolidated financial statements and disclosures in the accompanying notes, including estimates of probable losses and expenses, as of the date of the accompanying unaudited condensed consolidated financial statements. Management considers many factors in selecting appropriate financial accounting policies and in developing the estimates and assumptions that are used in the preparation of these unaudited condensed consolidated financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including the expected business and operational changes, the sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and management must select an amount that falls within that range of reasonable estimates. Actual results could differ materially from the estimates and assumptions used in the preparation of the accompanying unaudited condensed consolidated financial statements under different assumptions or conditions.
Inventory	Inventory Inventory consists of finished products, work-in-process and raw materials and is valued at the lower of cost or net realizable value. Cost may include materials, labor and manufacturing overhead. Cost is determined by the first in, first out inventory method. The carrying value of inventory is reviewed for potential impairment whenever indicators suggest that the cost of inventory exceeds the carrying value and management adjusts the inventory to its net realizable value. The Company also periodically evaluates inventory for estimated losses from excess quantities and obsolescence and writes down the cost of inventory to net realizable value at the time such determinations are made. Net realizable value is determined using the estimated selling price, in the ordinary course of business, less estimated costs of completion and disposal.
Revenue Recognition	Revenue Recognition Contracts with Customers The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods and services. Specifically, the Company applies the following five core principles to recognize revenue: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, the Company satisfies a performance obligation. Revenue recorded from continuing operations is generated from sales of the GentleWave Console and related PIs and accessories and services on its GentleWave Console. The Company’s products are sold primarily in the United States and Canada directly to customers through its field sales force. Performance Obligations The Company’s performance obligations from continuing operations primarily arise from the manufacture and delivery of the GentleWave System, related PIs and accessories, and to a lesser extent, performance of service contracts on its GentleWave Consoles. Payment terms are typically on open credit terms consistent with industry practice and do not have significant financing components. Consideration may be variable based on volume. The Company considers the individual deliverables in its product offering as separate performance obligations and assesses whether each promised good or service is distinct. The total contract transaction price is determined based on the consideration expected to be received, based on the stated value in contractual arrangements or the estimated cash to be collected in no-contracted arrangements, and is allocated to the identified performance obligations based upon the relative standalone selling prices of the performance obligations. The stand-alone selling price is based on an observable price offered to other comparable customers. The Company estimates the standalone selling price using the market assessment approach considering market conditions and entity-specific factors including, but not limited to, features and functionality of the products and services, geographies, type of customer and market conditions. The Company regularly reviews and updates standalone selling prices as necessary. The consideration the Company receives in exchange for its goods or services is only recognized when it is probable that a significant reversal will not occur. The consideration to which the Company expects to be entitled includes a stated list price, less various forms of variable consideration. The Company estimates related variable consideration at the point of sale, including discounts, product returns, refunds, and other similar obligations. Revenue is recognized over time when the customer simultaneously receives and consumes the benefits provided by the Company’s performance. Revenue is recognized at a point in time if the criteria for recognizing revenue over time are not met, and the Company has transferred control of the goods to the customer. Product revenue is recognized at a point in time when the Company has transferred control to the customer, which is generally when title of the goods transfers to the customer. Sales of extended service contracts are recorded as deferred revenue until such time as the standard warranty expires, which is generally up to two years from the date of sale. Service contract revenue is recognized on a straight-line basis over time consistent with the life of the related service contract in proportion to the costs incurred in fulfilling performance obligations under the service contract. The Company generally does not experience significant returns. If necessary, a provision is recorded for estimated sales returns and allowances and is deducted from gross product revenue to arrive at net product revenue in the period the related revenue is recorded. These estimates are based on historical sales returns and allowances and other known factors. Actual returns and claims in any future period are inherently uncertain and thus may differ from these estimates. If actual or expected future returns and claims are significantly greater or lower than the reserves established, a reduction or increase to revenue will be recorded in the period in which such a determination is made. All non-income government-assessed taxes (sales and use taxes) collected from the Company’s customers and remitted to governmental agencies are recorded in accrued expenses until they are remitted to the government agency. The Company has adopted the practical expedient permitting the direct expensing of costs incurred to obtain contracts where the amortization of such costs would occur over one year or less, and it applied to substantially all the Company’s contracts. Contract liabilities The Company recognizes a contract liability when a customer pays for goods or services for which the Company has not yet transferred control. The balances of the Company’s contract liabilities are as follows: March 31, December 31, 2024 2023 (in thousands) Total contract liabilities - extended service contracts $ 1,048 $ 920 Less: long-term portion 281 302 Contract liabilities – current $ 767 $ 618 Contract liabilities are included within other current liabilities and other long-term liabilities in the accompanying unaudited condensed consolidated balance sheets. Revenue recognized during the three months ended March 31, 2024 and 2023 that was included in the contract liability balance as of December 31, 2023 and 2022 was $ 0.2 million and $ 0.1 million, respectively. Disaggregation of revenue The Company disaggregates revenue from contracts with customers by segment and by the timing of when goods and services are transferred, which depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected. The following table provides information regarding disaggregated revenues and the timing of when goods and services are transferred: Three Months Ended March 31, 2024 2023 (in thousands) Product revenue recognized at a point in time $ 6,730 $ 8,524 Service revenue recognized over time 317 154 Total revenue $ 7,047 $ 8,678 No individual customer accounted for more than 10% of sales for the three months ended March 31, 2024 and 2023.
Warranty Reserve	Warranty Reserve The Company provides a standard warranty on its GentleWave Systems for a specified period of time. For the three months ended March 31, 2024 and 2023, GentleWave Systems sold were covered by the warranty for a period of up to two years from the date of sale. Estimated warranty costs are recorded as a liability at the time of delivery with a corresponding provision to cost of sales. Warranty accruals are estimated based on the current product costs, the Company’s historical experience, management’s expectations of future conditions and standard maintenance schedules. The Company evaluates this reserve on a regular basis and makes adjustments as necessary. The following table provides a reconciliation of the change in estimated warranty liabilities for the three months ended March 31, 2024 and 2023: Three Months Ended March 31, 2024 2023 (in thousands) Balance at beginning of period $ 1,269 $ 1,930 Provision for warranties issued 200 195 Warranty costs incurred ( 427 ) ( 368 ) Balance at end of period $ 1,042 $ 1,757 Current portion $ 980 $ 1,335 Non-current portion 62 422 Total $ 1,042 $ 1,757 The warranty liabilities, current and non-current, are included in other current liabilities and other liabilities, respectively, on the unaudited condensed consolidated balance sheets.
