ITEM 9A. CONTRO LS AND PROCEDURES
Evaluation of disclosure controls and procedures
The Company maintains a system of disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, which are designed to provide reasonable assurance that information required to be disclosed in the reports that the Company files or submits under the Exchange Act, is recorded, processed, summarized and reported accurately and completely within the time periods specified in the SEC’s rules and forms. These disclosure controls and procedures include, among other processes, controls and procedures designed to ensure that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Due to inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Further, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions over time, or that the degree of compliance with the policies and procedures may deteriorate. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2025. Based upon the evaluation described above, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2025, our disclosure controls and procedures were effective at the reasonable assurance level.
Changes in internal controls over financial reporting
There has been no change in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or 15d-15 that occurred during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Limitations on effectiveness of controls
In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Because of the inherent limitations in any control system, misstatements due to error or fraud may occur and not be detected.
Management’s report on internal control over financial reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our management, including our Chief Executive Officer and Chief Financial Officer, conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), or COSO. Based on our evaluation under the COSO framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2025 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. GAAP.
The effectiveness of our internal control over financial reporting as of December 31, 2025 has been audited by our independent registered public accounting firm, Deloitte & Touche LLP, as stated in their report, which appears herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the stockholders and the Board of Directors of Inogen, Inc.
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Inogen, Inc. and subsidiaries (the “Company”) as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated February 27, 2026, expressed an unqualified opinion on those financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the stockholders and the Board of Directors of Inogen, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Inogen, Inc. and subsidiaries (the “Company”) as of December 31, 2025 and 2024, the related consolidated statements of comprehensive loss, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2026, expressed an unqualified opinion on the Company's internal control over financial reporting.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Sales Revenue (Amounts Deferred for Lifetime Warranty) – Refer to Note 2 to the financial statements
Critical Audit Matter Description
The Company offers a lifetime warranty for direct-to-consumer sales of its oxygen concentrators. For a fixed price, the Company agrees to provide a fully functional oxygen concentrator for the remaining life of the patient. Lifetime warranties are only offered to patients upon the initial sale of oxygen concentrators directly from the Company and are non-transferable. Lifetime warranties are considered to be a distinct performance obligation that are accounted for separately from its sale of oxygen concentrators with a standard warranty of three years.
The revenue is allocated to the distinct lifetime warranty performance obligation based on a relative stand-alone selling price (SSP) method. The Company has vendor-specific objective evidence of the selling price for its equipment. To determine the selling price of the lifetime warranty, the Company uses its best estimate of the SSP for the distinct performance obligation as the lifetime warranty is neither separately priced nor is the selling price available through third-party evidence. To estimate the selling price associated with the lifetime warranties, management considers the profit margins of service revenue, the average estimated cost of lifetime warranties and the price of extended warranties. Revenue from the distinct lifetime warranty is deferred after the delivery of the equipment and recognized based on an estimated mortality rate over five years, which is the estimated performance period of the contract based on the average patient life expectancy. Total deferred revenue related to the lifetime warranty performance obligation totaled $6.8 million at December 31, 2025.
F- 2
Determining the estimated SSP requires significant judgment by management, which is informed by considering Company specific and external data. The service period used to amortize the deferred revenue also requires significant management judgment as the Company has limited patient data and the determination of patient life expectancy is subjective in nature. Given the lack of stand-alone transactions together with the limited amount of data available for such offering, performing audit procedures to evaluate the estimated SSP and the service period for lifetime warranty required high degree of auditor judgment and an increased extent of effort.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to management’s judgments regarding the stand-alone selling price and deferred revenue service period included the following, among others:
• We tested the effectiveness of controls over deferred revenue for the lifetime warranty, including controls over the underlying data utilized and the selection of the stand-alone selling price and the deferred revenue service period.
• We evaluated the methodology used by management to develop the stand-alone selling price and independently estimated the stand-alone selling price selected by management. In performing these procedures, we compared the stand-alone selling price selected by management to the independent estimate, which utilized external evidence of similar term extended warranties for oxygen concentrators and the Company’s profit margins.
• We evaluated the reasonableness of the deferred revenue service period by comparing to patient average life expectancy in medical and other industry publications. We further evaluated the realization of deferred revenue by evaluating the appropriateness of the underlying mortality data.

Notes to the Consolidat ed F inancial Statements
(amounts in thousands, except share and per share amounts)
1. Nature of business
Inogen, Inc. or the Company, is a medical technology business that primarily focuses on respiratory health. The Company develops, manufactures, and markets innovative respiratory health products, including portable oxygen concentrators, or POCs, used to deliver supplemental long-term oxygen therapy to patients suffering from chronic respiratory conditions and the Simeox ® product for airway clearance treatment. In addition, we have started distributing the Inogen Voxi ® 5 stationary oxygen concentrator as well as the Aurora ® continuous positive airway pressure, or CPAP, masks in the United States. The Company’s proprietary Inogen One ® and Inogen Rove ® systems concentrate the air around the patient to offer a source of supplemental oxygen 24 hours a day, seven days a week with a battery and can be plugged into an outlet when at home, in a car, or in a public place with outlets available. While often used together with stationary oxygen concentrators and oxygen compressed gas tanks, the Company's POCs are designed to reduce the patient’s reliance on stationary concentrators and scheduled deliveries of tanks with a finite supply of oxygen, thereby improving patient quality of life and fostering mobility. The Company's Simeox product is a technology-enabled airway clearance and mucus management device predominantly aimed at serving patients requiring airway clearance, such as those with bronchiectasis – a condition characterized by damaged and widened bronchi that can occur in patients with cystic fibrosis, chronic obstructive pulmonary disease, or COPD, or other chronic respiratory diseases. The Voxi 5 stationary oxygen concentrator is used to provide continuous, long-term oxygen therapy to patients who need supplemental oxygen at home or in clinical settings. The Aurora CPAP masks are used to deliver CPAP therapy through a separate device primarily for treating obstructive sleep apnea, or OSA.
The Company was incorporated in Delaware on November 27, 2001. On February 14, 2014, the Company completed an initial public offering of common stock and began trading on the Nasdaq Global Select Market, trading under the ticker symbol “INGN”.
The Company incorporated Inogen Europe Holding B.V., a Dutch limited liability company, on April 13, 2017 . On May 4, 2017, Inogen Europe Holding B.V. acquired all issued and outstanding capital stock of MedSupport Systems B.V., or MedSupport, and began operating under the name Inogen Europe B.V. The Company merged Inogen Europe Holding B.V. and Inogen Europe B.V. on December 28, 2018. Inogen Europe B.V. is the remaining legal entity. The Company completed the acquisition of New Aera, Inc., or New Aera, on August 9, 2019. On September 14, 2023 , the Company completed the acquisition of all of the issued and outstanding capital stock of Physio-Assist SAS, or Physio-Assist, and its wholly-owned subsidiary PhysioAssist GmbH.
On January 25, 2025, the Company entered into a Strategic Collaboration Agreement, or the Collaboration Agreement, with Jiangsu Yuyue Medical Equipment & Supply Co., Ltd., or Yuwell. The collaboration with Yuwell has broadened the Company's product portfolio through distribution of certain respiratory products in the United States and select other territories, expanded and enhanced the Company's innovation pipeline through research and development collaboration, and is working to accelerate the entry of the Company's brand into the Chinese market. Pursuant to the Collaboration Agreement, the Company has started to distribute certain products supplied by Yuwell in the United States and specified countries and Yuwell has agreed to distribute certain products supplied by the Company in specified countries in the Asia-Pacific region.
2. Summary of s ignificant accounting policies
Basis of presentation
The consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP.
Basis of consolidation
The consolidated financial statements include the accounts of Inogen, Inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
F- 9
Accounting estimates
The preparation of consolidated 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 disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases these estimates and assumptions upon historical experience, existing and known circumstances, authoritative accounting pronouncements and other factors that management believes to be reasonable. Significant areas requiring the use of management estimates relate to revenue recognition, warranty reserves and expense, determining the stand-alone selling price, or Standalone Selling Price (SSP), and service period of performance obligations, rental asset valuations and write-downs, accounts receivable allowances for credit losses, returns and adjustments, impairment of goodwill, impairment of long-lived assets, stock-based compensation expense, income taxes, fair value of acquired intangible assets, goodwill, and financing receivable. Actual results could differ from these estimates.
Reclassifications
Certain reclassifications have been made to prior years’ financial statements to conform to current period financial statements’ presentation with no effect on previously reported results of operations, financial position, cash flows, or stockholders’ equity. These changes consisted of reclassifications to certain line items in the accompanying consolidated balance sheets and did not change total assets, liabilities or stockholders' equity as previously reported.
Revenue
The Company generates revenue primarily from sales and rentals of its products. The Company’s products consist primarily of its proprietary line of oxygen concentrators, and related accessories. Other revenue, which is included in sales revenue on the statements of comprehensive loss, primarily comes from service contracts, replacement parts and freight revenue for product shipments.
Sales revenue
Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue from product sales is generally recognized upon shipment of the product but is deferred for certain transactions when control has not yet transferred to the customer.
The Company’s product is generally sold with a right of return and the Company may provide other incentives, which are accounted for as variable consideration when estimating the amount of revenue to recognize. Returns and incentives are estimated at the time sales revenue is recognized. The provision for estimated returns is calculated based on historical data and future expectations. Sales revenue incentives within the Company’s contracts are estimated based on the most likely amounts expected on the related sales transactions and recorded as a reduction to revenue at the time of sale in accordance with the terms of the contract. Accordingly, revenue is recognized net of allowances for estimated returns and incentives.
For a fixed price, the Company also offers a lifetime warranty for direct-to-consumer sales for its oxygen concentrators. Lifetime warranties are only offered to patients upon the initial sale of oxygen concentrators directly from the Company and are non-transferable. Lifetime warranties are considered to be a distinct performance obligation that are accounted for separately from its sale of oxygen concentrators with a standard warranty of three years .
The revenue is allocated to the distinct lifetime warranty performance obligation based on a relative SSP method. The Company has vendor-specific objective evidence of the selling price for its equipment. To determine the selling price of the lifetime warranty, the Company uses its best estimate of the SSP for the distinct performance obligation as the lifetime warranty is neither separately priced nor is the selling price available through third-party evidence. To calculate the selling price associated with the lifetime warranties, management considers the profit margins of service revenue, the average estimated cost of lifetime warranties and the price of external and internal extended warranties. Revenue from the distinct lifetime warranty is deferred after the delivery of the equipment and recognized based on an estimated mortality rate over five years, which is the estimated performance period of the contract based on the average patient life expectancy.
Revenue from the sale of the Company’s repair services is recognized when the performance obligations are satisfied and collection of the receivables is probable. Other revenue from the sale of replacement parts is generally recognized when product is shipped to customers.
Freight revenue consists of fees associated with the deployment of products internationally and domestically when expedited freight options are requested or when minimum order quantities are not met. Freight revenue is generally recognized upon shipment of the product but is deferred if control has not yet transferred to the customer. Shipping and handling costs for sold products and rental assets shipped to the Company’s customers are included on the consolidated statements of comprehensive loss as part of cost of sales revenue and cost of rental revenue, respectively.
F- 10
The payment terms and conditions of customer contracts vary by customer type and the products and services offered. For certain products or services and customer types, the Company requires payment before the products or services are delivered to the customer. The timing of sales revenue recognition, billing and cash collection results in billed accounts receivable and deferred revenue in the consolidated balance sheets.
Contract liabilities primarily consist of deferred revenue related to lifetime warranties on direct-to-consumer sales revenue when cash payments are received in advance of services performed under the contract. The contract with the customer states the final terms of the sale, including the description, quantity, and price of each product or service purchase. The decrease in deferred revenue related to lifetime warranties for the years ended December 31, 2025 and December 31, 2024 was primarily driven by $ 4,238 and $ 5,088 , respectively, of revenues recognized that were included in the deferred revenue balances, partially offset by $ 1,136 and $ 1,695 , respectively, of payments received in advance of satisfying performance obligations. Deferred revenue related to lifetime warranties was $ 6,820 and $ 9,922 as of December 31, 2025 and December 31, 2024, respectively, and is classified within deferred revenue – current and noncurrent deferred revenue in the consolidated balance sheets.
The Company elected to apply the practical expedient in accordance with Accounting Standards Codification (ASC) 606— Revenue Recognition and did not evaluate contracts of one year or less for the existence of a significant financing component. The Company does not expect any revenue to be recognized over a multi-year period with the exception of revenue related to lifetime warranties.
The Company’s sales revenue is primarily derived from the sale of its oxygen concentrator products to individual consumers, home medical equipment providers, distributors, the Company’s private label partner and resellers worldwide. Sales revenue is classified into two areas: U.S. sales and international sales. The following table sets forth the Company’s sales revenue disaggregated by geographic region:

Rental revenue
The Company recognizes equipment rental revenue over the non-cancelable lease term, which is one month, less estimated adjustments, in accordance with Accounting Standards Codification (ASC) 842— Leases . The Company has separate contracts with each patient that are not subject to a master lease agreement with any third-party payor. The Company evaluates the individual lease contracts at lease inception and the start of each monthly renewal period to determine if it is reasonably certain that the monthly renewal option and the bargain renewal option associated with the potential capped free rental period would be exercised. Historically, the exercise of the monthly renewal and bargain renewal option is not reasonably certain at lease inception and at most subsequent monthly lease renewal periods. If the Company determines that the reasonably certain threshold for an individual patient is met at lease inception or at a monthly lease renewal period, such determination would impact the bargain renewal period for an individual lease. The Company would first consider the lease classification issue (sales-type lease or operating lease) and then appropriately recognize or defer rental revenue over the lease term, which may include a portion of the capped rental period. The Company has no t deferred any amounts associated with the capped rental period as of December 31, 2025 and December 31, 2024. Amounts related to the capped rental period have not been material in the periods presented.
The lease term begins on the date products are shipped to patients and are recorded at amounts estimated to be received under reimbursement arrangements with third-party payors, including Medicare, private payors, and Medicaid. Due to the nature of the industry and the reimbursement environment in which the Company operates, certain estimates are required to record net revenue and accounts receivable at their net realizable values. Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain payors may result in adjustments to amounts originally recorded. Such adjustments are typically identified and recorded at the point of cash application, claim denial or account review. The Company adjusts revenue for historical trends on revenue adjustments due to timely filings, deaths, hospice, and other types of analyzable adjustments on a monthly basis to record rental revenue at the expected collectible amounts. Accounts receivable is reduced by an allowance for credit losses which provides for those accounts from which payment is not expected to be received although product was delivered and revenue was earned. The determination that an account is uncollectible, and the ultimate write-off of that account occurs once collection is considered to be highly unlikely, and it is written-off and charged to the allowance at that time. Amounts billed but not earned due to the timing of the billing cycle are deferred and recognized in revenue on a straight-line basis over the monthly billing period. For example, if the first day of the billing period does not fall on the first of the month, then a portion of the monthly billing period will fall in the subsequent month and the related revenue and cost would be deferred based on the service days in the following month.
F- 11
The lease agreements generally contain lease and non-lease components. Non-lease components primarily include payments for supplies. The Company elected the practical expedient to treat the lease and non-lease components as a single lease component.
Rental revenue is recognized as earned, less estimated adjustments. Revenue not billed at the end of the period is reviewed for the likelihood of collections and accrued. The rental revenue stream is not guaranteed, and payment will cease if the patient no longer needs oxygen or returns the equipment. Revenue recognized is at full estimated allowable amounts; transfers to secondary insurances or patient responsibility have no net effect on revenue. Rental revenue is earned for that entire month if the patient is on service on the first day of the 30 -day period commencing on the recurring date of service for a particular claim, regardless of whether there is a change in condition or death after that date.
Included in rental revenue are unbilled amounts for which the revenue recognition criteria had been met as of period-end but were not yet billed to the payor. The estimate of net unbilled rental revenue recognized is based on historical trends and estimates of future collectability. In addition, the Company estimates potential future adjustments and write-offs of these unbilled amounts and includes these estimates in the allowance for adjustments and write-offs of rental revenue which is netted against gross receivables.
Product Warranty
The Company generally provides a warranty against defects in material and workmanship. The Company provides a three-year, five-year or lifetime warranty on Inogen One and Rove systems and a three-year and lifetime warranty on Inogen At Home systems sold. The Company only offers a lifetime warranty for direct-to-consumer sales of its oxygen concentrators. For a fixed price, the Company agrees to provide a fully functional oxygen concentrator for the remaining life of the patient. Lifetime warranties are only offered to patients upon the initial sale of oxygen concentrators directly from the Company and are non-transferable. The Company’s products are subject to regulatory and quality standards. The Company establishes an accrued liability for the estimated warranty costs at the time of revenue recognition, with a corresponding provision to cost of goods sold. The Company evaluates the liability each reporting period. Warranty costs are primarily estimated based on product return rates, historical warranty repair costs incurred and historical failure rates. The Company may make further adjustments to the warranty reserve when deemed appropriate, giving additional consideration to length of time the product version has been sold and future expectations of performance based on new features and capabilities. Actual warranty costs could differ materially from the estimated amounts.
Fair value accounting
ASC 820 — Fair Value Measurements and Disclosures creates a single definition of fair value, establishes a framework for measuring fair value in U.S. GAAP and expands disclosures about fair value measurements. ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement, and states that a fair value measurement is to estimate the price at which an orderly transaction to sell an asset or to transfer the liability would take place between market participants at the measurement date under current market conditions. Assets and liabilities adjusted to fair value in the balance sheet are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Level inputs, as defined by ASC 820, are as follows:
Level input
Input definition
Level 1
Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date.
Level 2
Inputs, other than quoted prices included in Level 1, that are observable for the asset or liability through corroboration with market data at the measurement date.
Level 3
Unobservable inputs that reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date.
The Company’s financial instruments consist of cash and cash equivalents, marketable securities, financing receivable, accounts receivable, accounts payable and accrued expenses. The carrying values of its financial instruments approximate fair value based on their short-term nature.
F- 12
Fair value of financial instruments
The Company obtained the fair value of its available-for-sale investments, which are not in active markets, from a third-party professional pricing service using quoted market prices for identical or comparable instruments, rather than direct observations of quoted prices in active markets. The Company's professional pricing service gathers observable inputs for all of its fixed income securities from a variety of industry data providers (e.g., large custodial institutions) and other third-party sources. Once the observable inputs are gathered, all data points are considered, and the fair value is determined. The Company validates the quoted market prices provided by its primary pricing service by comparing their assessment of the fair values against the fair values provided by its investment managers. The Company's investment managers use similar techniques to its professional pricing service to derive pricing as described above. As all significant inputs were observable, derived from observable information in the marketplace or supported by observable levels at which transactions are executed in the marketplace, the Company has classified its marketable securities within Level 2 of the fair value hierarchy.

Fair value of derivative instruments and hedging activities
The Company transacts business in foreign currencies and has international sales and expenses denominated in foreign currencies, subjecting the Company to foreign currency risk. The Company has entered into foreign currency forward contracts, generally with maturities of twelve months or less, to reduce the volatility of cash flows, primarily related to forecasted revenue denominated in certain foreign currencies. These contracts allow the Company to sell Euros in exchange for U.S. dollars at specified contract rates. Forward contracts are used to hedge forecasted sales over specific months. Changes in the fair value of these forward contracts designed as cash flow and balance sheet hedges are recorded as a component of accumulated other comprehensive income within stockholders’ equity and are recognized in the consolidated statements of comprehensive loss during the period which approximates the time the corresponding sales occur. The Company may also enter into foreign exchange contracts that are not designated as hedging instruments for financial accounting purposes. These contracts are generally entered into to offset the gains and losses on certain asset and liability balances until the expected time of repayment. Accordingly, any gains or losses resulting from changes in the fair value of the non-designated contracts are reported in other income (expense), net in the consolidated statements of comprehensive loss. The gains and losses on these contracts generally offset the gains and losses associated with the underlying foreign currency-denominated balances, which are also reported in other income (expense), net.
The Company records the assets or liabilities associated with derivative instruments and hedging activities at fair value based on Level 2 inputs in other current assets or other current liabilities, respectively, in the consolidated balance sheets. The Company had a related payable of $ 373 and a receivable of $ 351 as of December 31, 2025 and December 31, 2024, respectively.
The Company documents the hedging relationship and its risk management objective and strategy for undertaking the hedge, the hedging instrument, the hedged transaction, the nature of the risk being hedged, how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed prospectively and retrospectively, and a description of the method used to measure ineffectiveness. The Company assesses hedge effectiveness and ineffectiveness at a minimum quarterly but may assess it monthly. For derivative instruments that are designed and qualify as part of a cash flow hedging relationship, the effective portion of the gain or loss on the derivative is reported in other comprehensive loss and reclassified into earnings in the same periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current period earnings.
The Company will discontinue hedge accounting prospectively when it determines that the derivative is no longer effective in offsetting cash flows attributable to the hedge risk. The cash flow hedge is de-designated because a forecasted transaction is not probable of occurring, or management determines to remove the designation of the cash flow hedge. In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company continues to carry the derivative at its fair value on the balance sheets and recognizes any subsequent changes in the fair value in earnings. When it is probable that a forecasted transaction will not occur, the Company will discontinue hedge accounting and recognize immediately in earnings gains and losses that were accumulated in other comprehensive loss related to the hedging relationship.

Comprehensive income (loss) is the total net earnings and all other non-owner changes in equity. Except for net loss and unrealized gains and losses on cash flow hedges, the Company does not have any transactions or other economic events that qualify as comprehensive income (loss).
Fair value of earnout liability
The earnout liability will be adjusted to fair value at each reporting date until settled. At the end of each reporting period after the acquisition date, the arrangement is remeasured at its fair value, with changes in fair value recorded in earnings. Changes in fair value will be recognized in general and administrative expense.
The Company has obligations to pay up to $ 13,000 and $ 31,400 in earnout payments for the Physio-Assist acquisition and the New Aera acquisition, respectively, in cash if certain future financial and regulatory results are met. The earnout liabilities were valued using Level 3 inputs.
The fair value of the New Aera earnout was determined historically by employing a Monte Carlo simulation in a risk-neutral framework. The underlying simulated variable includes recognized revenue. The recognized revenue volatility estimate was based on a study of historical asset volatility for a set of comparable public companies. The model included other assumptions including the market price of risk, which was calculated as the weighted average cost of capital less the long-term risk-free rate. The earnout period for recognized revenue is each calendar year beginning with calendar year 2019 and ending on the calendar year in which the earnout consideration equals the earnout cap. As a result of the earnout requirements not expected to be met for New Aera due to the asset disposal, the Company considered the fair value measurement of the earnout liability to be $ 0 as of December 31, 2024 and 2023. Additional information on the loss on disposal of intangible asset contained later in this Note in Long-lived assets .
The fair value of the Physio-Assist earnout was valued using a probability weighted expected return methodology and was discounted using a rate and probability that appropriately captures the risk associated with the achievement of one of two milestones related to FDA De Novo authorization or 510(k) clearance for the Simeox Airway Clearance System within four years of the date of the closing of the transaction. Significant increases or decreases in these inputs could result in a significant impact on our fair value measurement. In December 2024 , the Company received FDA 510(k) clearance of its Simeox 200 device. Upon clearance, the Company became obligated to make the $ 13,000 cash earnout milestone payment. The payment was made within ten business days following the date clearance was received.
The reconciliation of the earnout liabilities measured and carried at fair value on a recurring basis is as follows:

Cash, cash equivalents, marketable securities and restricted cash
The Company considers all short-term highly liquid investments with a maturity of three months or less to be cash equivalents. Restricted cash is considered to be legally restricted as to withdrawal or usage. The Company's restricted cash is a legally restricted deposit held as a compensating balance against its corporate credit card balances. The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Company's consolidated balance sheet that are shown in aggregate in the accompanying consolidated statement of cash flows:

The Company’s marketable debt securities are classified and accounted for as available-for-sale. Cash equivalents are recorded at cost plus accrued interest, which is considered adjusted cost, and approximates fair value. Marketable debt securities are included in cash equivalents and marketable securities based on the maturity date of the security.
The Company considers investments with maturities greater than three months, but less than 18 months, to be marketable securities. Investments are reported at fair value with realized gains or losses reported in other income (expense), net.
F- 15
The Company reviews its investments to identify and evaluate investments that have an indication of possible impairment. Factors considered in determining whether a loss is temporary include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the investee, and the Company's intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. Expected credit losses are declines in fair value that are not expected to recover and are charged to other income (expense), net.
Accounts receivable
Accounts receivable are customer obligations due under normal sales and rental terms. The Company performs credit evaluations of the customers’ financial condition and generally does not require collateral. The allowance for doubtful accounts is maintained at a level that, in management’s opinion, is adequate to absorb potential losses related to accounts receivable and is based upon the Company’s continuous evaluation of the collectability of outstanding balances. Management’s evaluation takes into consideration such factors as past credit loss experience, economic conditions and information about specific receivables. The Company’s evaluation also considers the age and composition of the outstanding amounts in determining their net realizable value.
The allowance for credit losses is based on estimates, and ultimate losses may vary from current estimates. As adjustments to these estimates become necessary, they are reported in general and administrative expense for sales revenue in the periods in which they become known. The allowance is increased by credit losses, net of recoveries, and is reduced by direct write-offs.
The Company generally does not allow returns from providers for reasons not covered under its standard warranty. Therefore, provision for returns applies primarily to direct-to-consumer sales. This reserve is calculated primarily based on actual historical return rates under the Company’s 30-day return program and is applied to the related sales revenue for the last month of the quarter reported.
The Company also records an estimate for rental revenue adjustments which is recorded as a reduction of rental revenue and net rental accounts receivable balances. These adjustments result from contractual adjustments, audit adjustments, untimely claims filings, or billings not paid due to another provider performing same or similar functions for the patient in the same period, all of which prevent billed revenue from becoming realizable. The reserve is based on historical revenue adjustments as a percentage of rental revenue billed and unbilled during the related period.
When recording the allowance for credit losses for sales revenue, the credit loss expense account (general and administrative expense account) is charged and when recording allowance for sales returns, the sales returns account (contra sales revenue account) is charged.
The Company consistently applies its allowance estimation methodology from period-to-period. The Company’s best estimate is made on an accrual basis and adjusted in future periods as required. Any adjustments to the prior period estimates are included in the current period. As additional information becomes known, the Company adjusts its assumptions accordingly to change its estimate of accounts receivable. For the years ended December 31, 2025 and December 31, 2024 , the Company had increases of $ 1,242 and $ 2,127 , respectively, in the net rental revenue related to prior years.
Net accounts receivable (gross accounts receivable, net of allowances) balance concentrations by major category as of December 31, 2025 and December 31, 2024 were as follows:

Concentration of credit risk
Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents, marketable securities, financing receivable and accounts receivable. At times, cash account balances may be in excess of the amounts insured by the Federal Deposit Insurance Corporation. However, management believes the risk of loss to be minimal. The Company performs periodic evaluations of the relative credit standing of these institutions and has not experienced any losses on its cash and cash equivalents to date. The Company has also entered into hedging relationships with a single counterparty to offset the forecasted Euro-based revenues. The credit risk has been reduced due to a net settlement arrangement whereby the Company is allowed to net settle transactions with a single net amount payable by one party to the other.
Financing receivable
The Company's credit terms are predominately short term in nature from delivery of the product or invoicing. However, in certain circumstances, the Company offers extended payment terms to customers who have not met the payment terms of their original contract. In addition, certain customers may not comply with formal payment terms specified in their written agreements with us. When the period between the transfer of control of the products and payment is expected to be greater than one year, the Company will adjust the promised amount of consideration for the effects of a significant financing component. When contracts contain a significant financing component in which the Company is effectively financing the customer, a portion of the transaction price is recognized as interest income rather than revenue using a discount rate that reflects the rate that would be used in a separate financing transaction between the Company and the customer. The Company exercises judgment to determine an appropriate interest rate considering the customer’s credit characteristics and current economic conditions.
Based on an agreement reached on December 31, 2024 with a customer, the Company agreed to a revised payment schedule through 2028 for $ 7,500 in outstanding net accounts receivables related to prior year sales. As a result, the receivable was reclassified to a financing receivable. The related net accounts receivable as of December 31, 2023 was $ 8,639 for this customer. The current and noncurrent financing receivable related to this agreement was $ 1,473 and $ 3,274 as of December 31, 2025, respectively, and $ 1,751 and $ 4,747 as of December 31, 2024, respectively, and are classified within prepaid expenses and other current assets and other assets - noncurrent in the consolidated balance sheets.
Concentration of customers and vendors
The Company primarily sells its products to traditional home medical equipment providers, distributors, and resellers in the United States and in foreign countries on a credit basis. The Company also sells its products direct-to-consumers primarily on a prepayment basis. No customer represented more than 10% of the Company's net accounts receivable balance as of December 31, 2025 . One customer represented more than 10% of the Company's net accounts receivable balance with a net accounts receivable balance of $ 3,288 as of December 31, 2024.
F- 17
The Company also rents products directly to consumers for insurance reimbursement, which resulted in a customer concentration relating to Medicare’s service reimbursement programs. Medicare’s service reimbursement programs accounted for 61.9 %, 56.3 % and 67.7 % of rental revenue in 2025, 2024 and 2023 , respectively, and based on total revenue were 9.5 %, 9.5 % and 13.7 % for 2025, 2024 and 2023 , respectively. Accounts receivable balances relating to Medicare’s service reimbursement programs (including held and unbilled, net of allowances) amounted to $ 1,394 , or 3.6 %, of total net accounts receivable as of December 31, 2025 compared to $ 1,107 , or 4.8 %, of total net accounts receivable as of December 31, 2024.
The Company currently purchases raw materials from a limited number of vendors, which resulted in a concentration of three major vendors. The three major vendors supply the Company with raw materials used to manufacture the Company’s products. For the year ended December 31, 2025 , the Company’s three major vendors accounted for 17.9 %, 12.1 % and 10.5 %, respectively, of total raw material purchases. For the year ended December 31, 2024 , the Company’s three major vendors accounted for 19.6 %, 18.4 % and 10.2 %, respectively, of total raw material purchases.
A portion of revenue is earned from sales outside the United States. Approximately 78.2 %, 77.2 % and 77.7 % of the international revenue for the years ended December 31, 2025, 2024 and 2023, respectively, were invoiced in Euros. A breakdown of the Company’s revenue from U.S. and international sources for the years ended December 31, 2025, 2024 and 2023, respectively, is as follows:

Inventories
Inventories are stated at the lower of cost and net realizable value, using the first-in, first-out (FIFO) method. The Company records adjustments to inventory for potentially excess, obsolete, slow-moving or impaired items, and losses on firm purchase commitments as a component of cost of sales in the consolidated statements of comprehensive loss. The Company recorded noncurrent inventory related to inventories that are expected to be realized or consumed after one year of $ 966 and $ 1,291 as of December 31, 2025 and 2024, respectively. Noncurrent inventories are primarily related to raw materials purchased in bulk to support long-term expected repairs to reduce costs and are classified in other assets. During the years ended December 31, 2025, 2024 and 2023 , $ 1,899 , $ 562 and $ 2,187 , respectively, of inventory was transferred to rental equipment and was considered a noncash transaction in the production and purchase of rental equipment on the consolidated statements of cash flows. Inventories that are considered current as of December 31, 2025 were $ 14,945 of raw material and work-in progress and $ 11,024 of finished goods.
Property and equipment
Property and equipment are stated at cost. Depreciation and amortization are calculated using the straight-line method over the assets’ estimated useful lives as follows:
Rental equipment
1.5 - 8 years
Manufacturing equipment and tooling
3 - 5 years
Computer equipment and software
2 - 3 years
Furniture and equipment
5 years
Leasehold improvements
Lesser of estimated useful life or remaining lease term
Expenditures for additions, improvements and replacements are capitalized and depreciated to a salvage value of $ 0 . Repair and maintenance costs on rental equipment are included in cost of rental revenue on the consolidated statements of comprehensive loss. Repair and maintenance expense, which includes labor, parts and freight, for rental equipment was $ 7,071 , $ 6,413 and $ 5,143 for the years ended December 31, 2025, 2024 and 2023, respectively.
Included within property and equipment is construction in process, primarily related to the design and engineering of tooling, jigs and other machinery. In addition, this item also includes computer software or development costs that have been purchased but have not completed the final configuration process for implementation into the Company’s systems. These items have not been placed in service; therefore, no depreciation or amortization was recognized for these items in the respective periods.
Depreciation and amortization expense related to rental equipment and other property and equipment are summarized below for the years ended December 31, 2025, 2024 and 2023, respectively.

Long-lived assets
The Company accounts for the impairment and disposition of long-lived assets in accordance with ASC 360 — Property, Plant, and Equipment . Long-lived assets are reviewed for indicators of impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. No impairments were recorded for the years ended December 31, 2025 and 2024.
Goodwill and other identifiable intangible assets
Goodwill represents the excess acquisition cost over the fair value of the net tangible and intangible assets acquired. Goodwill is not amortized and is tested for impairment on an annual basis as of October 1 or whenever an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit or asset below its carrying amount. If the carrying amount of goodwill exceeds the implied estimated fair value, an impairment charge to current operations is recorded to reduce the carrying value to the implied estimated fair value.
The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value is less than its carrying amount. If, based on a review of qualitative factors, it is more likely than not that the fair value is less than its carrying amount, the Company will use a quantitative approach, and calculate the fair value and compare it to its carrying amount. If the fair value exceeds the carrying amount, there is no indication of impairment. If the carrying amount exceeds the fair value, an impairment loss is recorded equal to the difference.
Finite-lived intangible assets are amortized over their useful lives and are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Technology and customer relationships are amortized using the straight-line method.
Business combinations
The results of operations of the businesses acquired by the Company are included as of the acquisition date. The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated to goodwill. The Company may adjust the preliminary purchase price allocation, as necessary, for up to one year after the acquisition closing date if it obtains more information regarding asset valuations and liabilities assumed. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.
Leases
The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (ROU) assets, operating lease liability – current, and operating lease liability – noncurrent on the consolidated balance sheets.
F- 19
ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments as the rate implicit in each lease is generally not readily determinable. The operating lease ROU asset also includes any lease payments made to the lessor at or before the commencement date and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
The Company has lease agreements with lease and non-lease components. The Company elected the practical expedient to treat the lease and non-lease components as a single lease component. Additionally, the Company elected the practical expedient to not record leases with an initial term of twelve months or less on the consolidated balance sheets.
Loss contingencies
The Company is involved in various lawsuits, claims, investigations, and proceedings that arise in the ordinary course of business. The Company records a liability when it believes that it is both probable that a loss has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. The Company reviews at least quarterly and adjusts accordingly to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information.
Research and development
Research and development costs are expensed as incurred.
Advertising costs
Advertising costs, which were approximately $ 29,143 , $ 32,176 and $ 27,120 during the years ended December 31, 2025, 2024 and 2023 , respectively, are expensed as incurred, excluding the production costs of direct response advertising. Advertising costs are included in sales and marketing expense in the accompanying consolidated statements of comprehensive loss.
Restructuring charges
Restructuring costs include workforce reductions, termination benefits, office downsizing, centralizing manufacturing activities, and equipment relocation. Key assumptions used in calculating the restructuring costs include the terms of, and payments under, agreements to terminate certain contractual obligations and the timing of reductions in workforce.
Income taxes
The Company accounts for income taxes in accordance with ASC 740 — Income Taxes . Under ASC 740, income taxes are recognized for the amount of taxes payable or refundable for the current period and deferred tax liabilities and assets are recognized for the future tax consequences of transactions that have been recognized in the Company’s consolidated financial statements or tax returns. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided when it is more likely than not that some portion, or all, of the deferred tax asset will not be realized.
The Company accounts for uncertainties in income taxes in accordance with ASC 740-10 — Accounting for Uncertainty in Income Taxes . ASC 740-10 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This accounting standard also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
The Company recognizes interest and penalties on taxes, if any, within its income tax provision on its consolidated statements of comprehensive loss.
Accounting for stock-based compensation
The Company accounts for its stock-based compensation in accordance with ASC 718 — Compensation—Stock Compensation , which establishes accounting for share-based awards, exchanged for employee services and requires companies to expense the estimated fair value of these awards over the requisite employee service period. Stock–based compensation cost for stock options and employee stock purchase plan are determined at the grant date using the Black-Scholes option pricing model. Stock-based compensation cost for stock incentive awards is based on the number of shares ultimately expected to vest, estimated at each reporting date based on management’s expectations regarding the relevant performance criteria. The value of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the employee’s requisite service period.
F- 20
As part of the provisions of ASC 718, the Company is required to estimate potential forfeitures of stock grants and adjust compensation cost recorded accordingly. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of stock compensation expense to be recognized in future periods.
Foreign currency
The functional currency of the Company’s international subsidiaries is the local currency. The financial statements of the subsidiaries are translated to U.S. dollars using month-end exchange rates for assets and liabilities and average exchange rates for revenue, cost of revenue, operating expense and provision for income taxes. Translation gains and losses are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity. Foreign exchange transaction gains and losses resulting from the conversion of the transaction currency to functional currency are reflected as a component of foreign currency exchange gains or losses in other income (expense), net in the consolidated statements of comprehensive loss.
Collaboration Agreement
The Company evaluates the agreement with its collaboration partner to determine whether it is within the scope of ASC 808 — Collaborative Arrangements . The arrangement is within the scope of ASC 808 if it involves joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. This evaluation is performed throughout the life of the arrangement based on any changes in the roles and responsibilities of the parties under the arrangement. For collaboration arrangements within the scope of ASC 808 that contain multiple elements, the Company identifies the various transactions with the counterparty and determines if any unit of account is more reflective of a transaction with a customer and therefore should be accounted for within the scope of ASC 606. For transactions that are accounted for pursuant to ASC 808, an appropriate method of recognition and presentation is determined and consistently applied. If transactions that are accounted for pursuant to ASC 606, the Company applies its revenue recognition policies.
For transactions accounted for as collaborative arrangements under ASC 808, payments to and from collaboration partners associated with multiple activities in a collaboration arrangement are classified based on the nature of each separate activity. Payments associated with development activities performed are recorded as research and development expense when owed to collaboration partners, or as a reduction of research and development expense when due from collaboration partners. Payments associated with commercialization activities performed are recorded as general and administrative expense when owed to collaboration partners, or as a reduction of general and administrative expense when due from collaboration partners. At the end of each reporting period, the Company records a net amount due to or from collaboration partners for activities performed by the parties under the collaboration.
Loss per share
Loss per share, or EPS, is computed in accordance with ASC 260 — Earnings per Share and is calculated using the weighted-average number of shares of common stock outstanding during each period. Diluted EPS assumes the conversion, exercise or issuance of all potential common stock equivalents (which can include dilution of outstanding stock options, restricted stock units and restricted stock awards) unless the effect is to reduce a loss or increase the income per share. For purposes of this calculation, common stock subject to repurchase by the Company, options, and other dilutive awards are considered to be common stock equivalents and are only included in the calculation of diluted loss per share when their effect is dilutive.
Basic loss per share is calculated using the Company’s weighted-average outstanding shares of common stock. Diluted loss per share is calculated using the Company’s weighted-average outstanding shares of common stock including the dilutive effect of stock awards as determined under the treasury stock method.

(1) Unvested restricted stock units and restricted stock awards are not included as shares outstanding in the calculation of basic earnings per share. Vested restricted stock units and restricted stock awards are included in basic earnings per share if all vesting and performance criteria have been met. Performance-based restricted stock units and restricted stock awards are included in the number of shares used to calculate diluted earnings per share as long as all applicable performance criteria are met, and their effect is dilutive. Restricted stock awards are eligible to receive all dividends declared on the Company’s common stock during the vesting period; however, such dividends are not paid until the restrictions lapse.

Recently issued accounting pronouncements not yet adopted
In November 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses . Subsequently, in January 2025, the FASB issued ASU No. 2025-01 Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date . The new guidance requires public companies to disaggregate key expense categories such as inventory purchases, employee compensation and depreciation in their financial statements. This aims to improve investor insights into company performance. As clarified by ASU 2025-01, the guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact, if any, the adoption will have on its financial position and results of operations.
In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software . This standard is intended to improve the operability and application of guidance related to capitalized software development costs. The guidance is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the effect of the new guidance but does not expect it to have a material impact on the Company’s consolidated financial statements presentation or results of operations.
In November 2025, the FASB issued ASU No. 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements, which amends certain aspects of the hedge accounting guidance.

As a result of a decrease in Company’s public stock price that caused the Company's market capitalization to fall below its carrying amount (stockholders' equity) during July 2023 and noted by management to be more than temporary as the quarter progressed, a quantitative analysis was required to be performed during the quarter ended September 30, 2023. The Company used a discounted cash flow analysis based on Level 3 inputs and determined that the goodwill carrying amount exceeded its fair value and, as such, an impairment charge of $ 32,894 was incurred in the quarter ended September 30, 2023. Accumulated impairment losses were $ 32,894 as of December 31, 2025, 2024 and 2023.

5. Leases
The Company has entered into operating leases primarily for commercial buildings. These leases have terms which range from three years to 11 years, some of which include options to extend the leases for up to five years . Rent expense, including short-term lease cost, was $ 3,877 , $ 4,227 , and $ 4,017 for the years ended December 31, 2025, 2024 and 2023, respectively. Operating lease right-of-use assets and liabilities commencing after January 1, 2019 are recognized at commencement date based on the present value of lease payments over the lease term. The operating leases do not contain material residual value guarantees or material restrictive covenants.
In July 2023, the Company entered into an Assignment and Assumption of Lease Agreement in which a third party, referred to as the Assignee, assumed the rights, title, and interest in the lease, including assumption of lease payments. As inducement for the Assignee to enter into the agreement, the Company paid an incentive of $ 395 , provided for four months of free rent for the period October 1, 2023 through January 31, 2024, and conveyed ownership of certain items of the facility's furniture and equipment. Commencing February 1, 2024 and ending May 31, 2031, the Assignee assumed responsibility for the monthly lease payments. Notwithstanding the Assignee's assumption of lease payments, the Company remains the primary obligor under the lease to the landlord. The Assignee gained control to the facility on September 29, 2023, and related sublease income was not material.
Lease payments assumed by the Assignee are:

The Company operates in several taxing jurisdictions, including U.S. federal, multiple U.S. states, Netherlands, France and Germany. The statute of limitations has expired for all tax years prior to 2022 for federal and prior to 2018 for various state tax purposes. The statute of limitations has expired for all tax years prior to 2023 for France, prior to 2022 for Germany, and prior to 2021 for Netherlands purposes. However, the net operating loss generated on the Company’s federal and state tax returns in prior years may be subject to adjustments by the federal and state tax authorities.
As of December 31, 2025 , the Company had $ 138,741 , $ 82,286 and $ 19,102 of federal, state and foreign net operating loss carryforwards, respectively. Federal net operating loss carryforwards of $ 130,945 have an indefinite life while the remaining federal and state net operating loss carryforwards begin to expire in 2033 and 2028 , respectively, if not utilized. Foreign net operating loss carryforwards of $ 19,102 also have an indefinite life. As of December 31, 2025 , the Company had federal and California research and development credit carryforwards of $ 8,074 and $ 4,654 , respectively. The federal credit will begin to expire in 2026 ; the California credit has indefinite carryforward. As of December 31, 2025, the Company had a federal foreign tax credit carryforward of $ 774 . The federal credit will begin to expire in 2027 .
Utilization of the Company’s net operating loss and tax credit carryforwards may be subject to annual limitations arising from ownership change limitations provided by the Internal Revenue Code and similar state and foreign provisions. Such annual limitations could result in the expiration of the net operating loss and tax credit carryforwards before their utilization.
On July 4, 2025, the One Big Beautiful Bill Act , or OBBBA, was enacted into law. The OBBBA provides for significant U.S. tax law changes and modifications. The impacts of the new legislation are immaterial and included in the consolidated financial statements as of and for the period ended December 31, 2025.
The Company recognizes deferred tax assets to the extent it believes these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. The amount of deferred tax assets considered realizable is subject to adjustment in future periods if estimates of future taxable income are reduced. As of December 31, 2025 and 2024, the Company determined that net deferred tax assets are not more likely than not realizable based on cumulative three-year pretax losses and recorded a full valuation allowance. The Company’s valuation allowance may increase or decrease during the next 12 months based on future operating results. The increase in valuation allowance of $ 3,941 is attributable to losses generated in the current year.
As of December 31, 2025, unremitted earnings of the subsidiaries outside of the United States were approximatel y $ 7,301 , on which no deferred tax liability has been recorded. The Company’s intention is to indefinitely reinvest these earnings outside the United States. Upon distribution of those earnings in the form of a dividend or otherwise, the Company would be subject to both state income taxes and withholding taxes payable to various foreign countries. The amounts of such tax liabilities that might be payable upon repatriation of foreign earnings are not material.
The Company recognizes interest and penalties on taxes, within its income tax provision on its consolidated statements of comprehensive loss.
Included in the balance of unrecognized tax benefits as of December 31, 2025, 2024 and 2023 , were $ 3,133 , $ 2,922 and $ 2,778 , respectively, of tax benefits that, if recognized, would affect the effective tax rate.

7. Stockholders’ equity

Preferred stock
Pursuant to the amended and restated certificate of incorporation filed by the Company in connection with the completion of its initial public offering, the Company’s board of directors is authorized to issue up to 10,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, redemption rights, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of common stock. The issuance of preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing change in the Company’s control or other corporate action.

The Company grants restricted stock units, or RSUs, and restricted stock awards, or RSAs, under the 2014 and 2023 Plans and made one inducement grant of RSUs in 2024, or Stock Awards. The Stock Awards vest either based solely on the satisfaction of time-based service conditions or on the satisfaction of time-based service conditions combined with performance criteria. Stock Awards are subject to forfeiture if the holder’s services to the Company terminate before vesting.
Stock Awards granted with only time-based service vesting conditions generally vest over three-year and four-year service periods, as defined in the terms of each award. Stock Awards that vest based on the satisfaction of time-based service conditions combined with performance criteria generally vest over a three-year service and performance period, based on performance and/or market conditions established at the time of the award. The portion of the Stock Award that is earned may equal or be more or less than the targeted number of shares subject to the Stock Award depending on whether the performance criteria are met.

(1) Outstanding restricted stock units and restricted stock awards are based on the maximum payout of the targeted number of shares.
As of December 31, 2025 , the unrecognized compensation cost related to unvested employee restricted stock units was $ 9,515 , excluding estimated forfeitures. This amount is expected to be recognized over a weighted average period of 1.9 years.
Employee stock purchase plan
The Company’s 2014 Employee Stock Purchase Plan, or ESPP, provides all eligible employees the option to purchase shares of the Company’s common stock at a discount through payroll deductions. The expense recognized for shares purchased under the ESPP is equal to the 15 % discount the employee receives. As of December 31, 2025 , a total of 624,415 shares of common stock were available for future purchase under the ESPP. In 2025 , an additional 179,069 shares of common stock were reserved for issuance pursuant to future ESPP purchases as a result of the annual evergreen increase under the ESPP.

S tock-based compensation expense was calculated based on awards of stock options, restricted stock units and restricted stock awards expected to vest based on the Company’s historical award cancellations. The employee stock-based compensation expense recognized for the years ended December 31, 2025, 2024 and 2023 has been reduced for estimate forfeitures of restricted stock at a rate of 10.3 %, 8.3 % and 5.3 %, respectively. ASC 718 – Compensation-Stock Compensation requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
For the years ended December 31, 2025, 2024 and 2023, respectively, stock-based compensation expense recognized under ASC 718, included in cost of revenue, research and development expense, sales and marketing expense, and general and administrative expense was as follows:

Valuation assumptions
The employee stock-based compensation expense is recognized under ASC 718. Stock-based compensation cost for stock awards is based on the number of shares ultimately expected to vest, estimated at each reporting date based on management’s expectations regarding the relevant performance criteria. The value of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the employee’s requisite service period for stock awards with a time-based service condition and on a graded vesting basis over the employee’s requisite service period for stock awards with performance and time-based service conditions.
Stock-based compensation cost for the employee stock purchase plan is determined at the grant date using the Black-Scholes option pricing model. During the years ended December 31, 2025, 2024 and 2023, the Company did not grant any stock option awards.
The following table displays the assumptions that have been applied to estimate the fair value of the Company’s shares to be issued under the ESPP using the Black-Scholes option pricing model.

For the years ended December 31, 2025 and 2024, the Company granted certain RSU awards based on achievement of the market condition total shareholder return, or TSR, relative to an objectively selected group of industry peers over a three-year period, with payouts ranging from zero to 200 percent of the target award. The fair value of the TSR component of the awards was $ 12.59 and $ 6.94 per share for the 2025 and 2024 awards, respectively, determined on the grant date using a Monte Carlo simulation model based on the following assumptions:

8. Commitments and contingencies
Purchase obligations
The Company had approximately $ 62,163 of outstanding purchase orders due within one year with its outside vendors and suppliers as of December 31, 2025 . The Company has $ 427 and $ 672 accrued within accounts payable and other accrued expenses in the consolidated balance sheet as of December 31, 2025 and 2024, respectively, related to estimated losses for firm commitment contractual obligations under these agreements. Losses on these firm commitment contractual obligations are recognized based upon the terms of the respective agreement and similar factors considered for the write-down of inventory, including expected sales requirements as determined by internal sales forecasts.

During the year ended December 31, 2023, the Company recorded $ 5,014 of changes in estimates related to preexisting warranties due to data and information that became available during that year. The changes in estimates were primarily due to the increased cost to repair for all products stemming from the current year inflationary environment and increased product failure rates.
Legislation and HIPAA
The healthcare industry is subject to numerous laws and regulations of federal, state and local governments. These laws and regulations include, but are not necessarily limited to, matters such as licensure, accreditation, government healthcare program participation requirements, reimbursement for patient services, and Medicare and Medicaid fraud and abuse. Compliance with government laws and regulations can be subject to future government review and interpretation as well as regulatory actions unknown or unasserted at this time. The Health Insurance Portability and Accountability Act of 1996, or HIPAA, was enacted to ensure health insurance portability, reduce healthcare fraud and abuse, guarantee security and privacy of health information, and enforce standards for health information. The Health Information Technology for Economic and Clinical Health Act, or the HITECH Act, in part, imposes notification requirements of certain security breaches relating to protected health information. The Company is not aware of any pending claims against it under the HIPAA and HITECH regulations that are applicable to the Company’s business.
Legal proceedings
On March 3, 2023, APT Electronics Inc., or APT, filed a lawsuit in the Superior Court of the State of California, County of Orange against the Company, or the APT Action. APT alleged that the Company failed to pay APT for all services, inventory, and materials due to it in connection with the parties’ prior supply arrangement. APT sought damages, pre-judgment interest, costs, and attorneys’ fees.
The parties reached a mutually agreeable settlement in August 2025. The Company paid $ 1,750 to APT on August 26, 2025, finalizing the payment of this settlement and incurred $ 668 in legal settlement costs, both classified within general and administrative expense. Based on the parties’ request, the court dismissed the APT Action with prejudice on August 27, 2025. Although the Company came to a settlement agreement to remove the risk of uncertain legal and financial obligations going forward, the Company in no way assumed or admitted any wrongdoing.
The Company is party to various legal proceedings and investigations arising in the normal course of business. The Company carries insurance, subject to specified deductibles under the policies, to protect against losses from certain types of legal claims. At this time, the Company does not anticipate that any of these other proceedings arising in the normal course of business will have a material adverse effect on the Company’s business. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors.

9. Restructuring charges
For the years ended December 31, 2025 and December 31, 2024, the Company had no restructuring costs. The Company incurred $ 3,426 of restructuring costs during the year ended December 31, 2023, primarily in connection with the Company's cost reduction initiatives, which were recorded within general and administrative expense in the consolidated statements of comprehensive loss. The restructuring charges consisted primarily of severance and termination benefits. Other related costs consisted of targeted workforce reductions, office downsizing, centralizing manufacturing activities, and equipment relocation. The Company had $ 0 of accrued liabilities related to restructuring charges as of December 31, 2025 and 2024.
10. Foreign currency exchange contracts and hedging
As of December 31, 2025 , the Company’s total non-designated and designated derivative contracts had notional amounts totaling approximately $ 42,714 and $ 0 , respectively. As of December 31, 2024 , the Company’s total non-designated and designated derivative contracts had notional amounts totaling approximately $ 46,288 and $ 0 , respectively. These contracts were comprised of offsetting contracts with the same counterparty, each expires within one to two months . During the years ended December 31, 2025 , 2024 and 2023 these contracts had, net of tax, an unrealized gain or loss of $ 0 .
The nonperformance risk of the Company and the counterparty did not have a material impact on the fair value of the derivatives. During the years ended December 31, 2025, 2024 and 2023 , there were no ineffective portions relating to these hedges and the hedges remained effective through their respective settlement dates. As of December 31, 2025 , the Company had no designated hedges and four non-designed hedges. As of December 31, 2024 , the Company had no designated hedges and five non-designated hedges.
11. Segments
Operating segments are defined as components of an enterprise engaging in business activities for which separate financial information is available that is regularly evaluated by the Group’s chief operating decision makers, or CODM. Based on the criteria established by ASC 280 Segment Reporting , the Company’s CODM has been identified as the executive leadership team, or ELT, which includes the Chief Executive Officer and the Chief Financial Officer . The ELT reviews a monthly executive reporting package based on consolidated results of the Company when making decisions about allocating resources and assessing performance. The Company derives revenues from customers through the development, manufacturing, marketing, sales, and rental of respiratory products. The Company considered the following when assessing its segment determination: the similar nature of the Company’s products and services that are included together in the oxygen therapy and respiratory care markets; the consistent production processes used to manufacture the Company’s products; the same channels used to distribute and sell the Company’s products; and the products align and qualify as respiratory durable medical equipment per the regulatory definition. Therefore, the Company determined that it operates and reports in only one operating and reportable segment. The CODM assesses performance for the one operating and reportable segment and decides how to allocate resources based on the segment profit or loss measure and adjusted EBITDA. The measure of segment assets is reported on the balance sheet as “total assets.” The CODM determined that the Company’s segment profit or loss measure that is most consistent with GAAP measurement principles is net loss to evaluate income and loss generated from segment assets (return on assets). Net Loss for the Company’s one operating and reportable segment is reported on the consolidated statements of comprehensive loss. The Company evaluated the monthly executive reporting package and did not identify any significant or other expenses for disclosure that are not already presented on the consolidated statements of comprehensive loss.
12. Subsequent Event
On February 20, 2026, subsequent to the balance sheet date of December 31, 2025, the Company’s Board of Directors authorized a share repurchase program under which the Company may repurchase up to $ 30.0 million of its outstanding common stock. The repurchase program expires on either December 31, 2027 , or once the maximum authorized dollar amount has been utilized, whichever occurs first. Repurchases under the program may be made from time to time through open market purchases at prevailing market prices, in compliance with Rule 10b-18 under the Exchange Act, including through Rule 10b5-1 trading plans. The share repurchase program does not obligate the Company to make any repurchases and may be modified, suspended, or terminated by the Company at any time without prior notice. The amount and timing of repurchases are subject to a variety of factors including liquidity, share price, market conditions, and legal requirements.
