    Condensed Notes to the Consolidated Financial Statements

    (amounts in thousands, except share and per share amounts)

    1. Business overview

    Inogen, Inc. (Company or Inogen) was incorporated in Delaware on November 27, 2001. The Company is a medical technology business that primarily develops, manufactures, and markets innovative portable oxygen concentrators (POCs) used to deliver supplemental long-term oxygen therapy to patients suffering from chronic respiratory conditions. Traditionally, these patients have relied on stationary oxygen concentrator systems for use in the home and oxygen tanks or cylinders for mobile use, which the Company refers to as the delivery model. The tanks and cylinders must be delivered regularly and have a finite amount of oxygen, which requires patients to plan activities outside of their homes around delivery schedules and a finite oxygen supply. Additionally, patients must attach long cumbersome tubing to their stationary concentrators simply to enable mobility within their homes. The Company's proprietary Inogen One® and Inogen Rove systems concentrate the air around the patient to offer a source of supplemental oxygen anytime, anywhere with a battery and can be plugged into an outlet when at home, in a car, or in a public place with outlets available. The Company's Inogen One systems 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 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. (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. Inogen completed the acquisition of New Aera, Inc. (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 (Physio-Assist) and its wholly-owned subsidiary PhysioAssist GmbH.

    2. Basis of presentation and summary of significant 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 (U.S. GAAP).

    The results of operations for the three months ended March 31, 2024 shown in this report are not necessarily indicative of results to be expected for the full year ending December 31, 2024. In the opinion of the Company’s management, the information contained herein reflects all adjustments, consisting of only normal recurring adjustments, necessary for a fair presentation of the Company’s results of operations, financial position, cash flows, and stockholders’ equity. Certain footnote disclosures normally included in annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to Securities and Exchange Commission (SEC) rules and regulations relating to interim financial statements. The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K filed with the SEC on March 1, 2024. Except as further described below, there have been no significant changes in the Company’s accounting policies from those disclosed in its Annual Report on Form 10-K filed with the SEC on March 1, 2024.

    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.

    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 (SSP) and service period of performance obligations, rental asset valuations and write-downs, accounts receivable allowances for bad debts, returns and

    8


     

    adjustments, impairment of goodwill, impairment of long-lived assets, stock-based compensation expense, income taxes, fair value of acquired intangible assets and goodwill, and fair value of earnout liabilities. Actual results could differ from these estimates.

    3. Acquisitions

    On July 10, 2023, the Company entered into a share purchase agreement to acquire Physio-Assist, which is in the business of the design, production, and marketing of medical devices for bronchial decongestion (airway clearance technique) for patients suffering from obstructive respiratory diseases. On September 14, 2023, the Company completed the acquisition of all of the issued and outstanding capital stock of Physio-Assist and its wholly-owned subsidiary PhysioAssist GmbH for a purchase price consisting of $32,250 in cash consideration and the fair value of a potential earnout of $3,178 based on future regulatory clearances.

    A potential earnout payment of either $13,000 (without a clinical trial requirement) or $11,000 (with a required clinical trial less related development costs) is dependent upon the achievement of one of two milestones related to U.S. Food and Drug Administration (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. The fair value of the earnout liability was measured using the probability weighted expected return methodology and was discounted using a rate and probability that appropriately captures the risk associated with the obligation.

    Assets and liabilities of the acquired company were recorded at their estimated fair values at the date of acquisition. The excess purchase price over the fair value of net tangible assets and identifiable intangible assets acquired has been allocated to goodwill. Goodwill represents the expected synergies with the existing business, the acquired assembled workforce, and future cash flows after the acquisition. The fair value assigned to the identifiable intangible assets was determined primarily by using the excess earnings method. The key assumptions included in the excess earnings method included revenue recognized, cost of revenue, and the discount rate.

    The Company's allocation of the purchase price of Physio-Assist is preliminary and any measurement period adjustments that result from the finalization of the purchase price allocation will be recorded retrospectively to the acquisition date. Changes are possible and could change the allocation of the purchase price.

    The following table summarizes the preliminary allocation of the purchase price over the estimated fair value of the assets acquired and liabilities assumed in the acquisition of Physio-Assist:

    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. Medicare's service reimbursement programs represented more than 10% of the Company's total revenue for the three months ended March 31, 2024 and March 31, 2023. One customer represented more than 10% of the Company’s net accounts receivable balance with a net accounts receivable balance of $6,665 as of March 31, 2024, and two customers each represented more than 10% of the Company's net accounts receivable balance with net accounts receivable balances of $8,639 and $4,994, respectively, as of December 31, 2023.

    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 58.4% and 73.8% of rental revenue in the three months ended March 31, 2024 and 2023, respectively, and based on total revenue were 11.2% and 16.6% for the three months ended March 31, 2024 and 2023, respectively. Accounts receivable balances relating to Medicare’s service reimbursement programs (including held and unbilled, net of allowances) amounted to $1,427 or 3.5% of total net accounts receivable as of March 31, 2024 compared to $2,059 or 4.9% of total net accounts receivable as of December 31, 2023.

    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 three months ended March 31, 2024, the Company’s three major vendors accounted for 24.6%, 17.2%, and 10.0%, respectively, of total raw material purchases. For the three months ended March 31, 2023, the Company’s three major vendors accounted for 34.1%, 13.1%, and 7.3%, respectively, of total raw material purchases.

    A portion of revenue is earned from sales outside the United States. Approximately 79.9% and 77.0% of the non-U.S. revenue for the three months ended March 31, 2024 and 2023, respectively, were invoiced in Euros. A breakdown of the Company’s revenue from U.S. and non-U.S. sources for the three months ended March 31, 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 our 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 $1,377 and $1,225 as of March 31, 2024 and December 31, 2023, 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 three months ended March 31, 2024 and 2023, $331 and $1,013, 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 consist of the following:

    7. Loss per share

    Loss per share (EPS) is computed in accordance with ASC 260—Earnings per Share and is calculated using the weighted average number of common shares 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 common shares. Diluted loss per share is calculated using the Company's weighted-average outstanding common shares including the dilutive effect of stock awards as determined under the treasury stock method.

    The computation of EPS is as follows:

    Unvested restricted stock units and restricted stock awards are not included as shares outstanding in the calculation of basic earnings per share.

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 shares during the vesting period; however, such dividends are not paid until the restrictions lapse.
    (2)
    Due to net losses for the three months ended March 31, 2024 and March 31, 2023, diluted loss per share is the same as basic.

    8. 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. As of December 31, 2023, the Company recorded a full valuation allowance of $59,968. As of March 31, 2024, the Company continued to record a valuation allowance against its domestic deferred tax assets.

    The Company accounts for uncertainties in income tax 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.

    9. Stockholders’ equity

    Stock incentive awards

    The Company grants restricted stock units (RSUs) under the 2014 and 2023 Plans (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 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 criteria 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.

    Employee stock purchase plan

     

    The Company’s 2014 Employee Stock Purchase Plan (ESPP) provides for the grant to all eligible employees an option to purchase stock under the ESPP, within the meaning Section 423 of the Internal Revenue Code. The ESPP permits participants to purchase common stock through payroll deductions of up to 15% of their eligible compensation, which includes a participant’s base straight time gross earnings, incentive compensation, bonuses, overtime, and shift premium, but exclusive of payments for equity compensation and other similar compensation. A participant may purchase a maximum of 1,500 shares during a purchase period. Amounts deducted and accumulated by the participant are used to purchase shares of the Company’s common stock at the end of each six-month period. The purchase price of the shares will be 85% of the lower of the fair market value of the Company’s common stock on the first trading day of each offering period or on the exercise date. The offering periods are currently approximately six months in length beginning on the first business day on or after March 1 and September 1 of each year and ending on the first business day on or after September 1 and March 1 approximately six months later.

    As of March 31, 2024, a total of 658,823 shares of common stock were available for sale pursuant to the ESPP.

    The number of shares available for sale under the ESPP is increased annually on the first day of each fiscal year by an amount equal to the least of:

    •
    179,069 shares;
    •
    1.5% of the outstanding shares of the Company’s common stock on the last day of the Company’s immediately preceding fiscal year; or
    •
    such other amount as may be determined by the administrator.

    For 2024, an additional 179,069 shares were added to the ESPP share reserve pursuant to the provision described above.

    Contract liabilities

    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 three months ended March 31, 2024 was primarily driven by $1,448 of revenue recognized that were included in the deferred revenue balances as of December 31, 2023, partially offset by $535 of payments received in advance of satisfying performance obligations. Deferred revenue related to lifetime warranties was $12,402 and $13,315 as of March 31, 2024 and December 31, 2023, respectively, and is classified within deferred revenue - current and deferred revenue - noncurrent in the consolidated balance sheet.

    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 (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 (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

    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.

    19


     

    11. Foreign currency exchange contracts and hedging

    As of March 31, 2024 and March 31, 2023, the Company’s total non-designated and designated derivative contracts had notional amounts totaling approximately $37,425 and $0, respectively, and $8,041 and $2,445, respectively. These contracts were comprised of offsetting contracts with the same counterparty, each expires within one month. During the three months ended March 31, 2024 and 2023, these contracts had, net of tax, an unrealized gain (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 three months ended March 31, 2024, there were no ineffective portions relating to these hedges and the hedges remained effective through their respective settlement dates. During the three months ended March 31, 2023, there were no ineffective portions related to these hedges. As of March 31, 2024, the Company had no designated hedges and four non-designated hedges. As of March 31, 2023, the Company had no designated hedges and one non-designated hedge.

    Critical accounting policies and estimates

    Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements which have been prepared in accordance with generally accepted accounting principles in the United States of America, or U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and related disclosure of contingent assets and liabilities, revenue and expenses at the date of the financial statements. Generally, we base our estimates on historical experience and on various other assumptions in accordance with U.S. GAAP that we believe to be reasonable under the circumstances. Actual results may differ from these estimates and such differences could be material to the financial position and results of operations.

    Critical accounting policies and estimates are those that we consider the most important to the portrayal of our financial condition and results of operations because they require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Our critical accounting policies and estimates include those related to:

    •
    revenue recognition;
    •
    acquisitions and related acquired intangible assets and goodwill; and
    •
    long-lived asset impairment.

    There have been no material changes in our critical accounting policies and estimates in the preparation of our consolidated financial statements during the three months ended March 31, 2024 compared to those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on March 1, 2024.

    Recent accounting pronouncements

    Information about recently adopted and proposed accounting pronouncements, if applicable, is included in Note 2 to our consolidated financial statements in Part I, Item 1 of this Quarterly Report under the heading “Recent Accounting Pronouncements” and is incorporated herein by reference.

    Macroeconomic environment

    The global economy is experiencing increased inflationary pressures. The macroeconomic environment has had significant and potentially will continue to have unexpected adverse effects on businesses and healthcare institutions around the world and has and may continue to negatively impact our consolidated operating results.

    We expect minimal inflated costs related to the acquisition of semiconductor chips to impact our cost of sales revenue throughout 2024. We incurred significant costs associated with acquiring chips on the open market and a portion of these costs increased our inventory given that these components were not yet in finished products that were sold during the period.

    23


     

    We also have experienced, along with most other companies across many industries, the macroeconomic impact of a challenging employment environment related to hiring and retaining employees and wage inflation. We expect that these hiring, retention, and wage inflation challenges, as well as challenges related to maintaining our current workforce, will continue through 2024. These challenges may negatively affect our ability to grow our business and keep our best employees or increase our cost of operations. In response we have implemented more flexible workplace requirements for certain roles, including remote workplace opportunities, but we still expect to be challenged by the macroeconomic employment environment.

    For additional information on risk factors that could impact our results, please refer to the sections entitled "Risk Factors" in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K.

    Overview

    We are a medical technology company that primarily develops, manufactures, and markets innovative portable oxygen therapy solutions for patients with chronic respiratory conditions. Our leading portfolio of innovative POCs is optimized to deliver high output ratio-to-weight, meaningful sound suppression and among the longest run times in the industry so that we can meet the needs of patients across a variety of disease states. We are positioned in the market as both a medical technology company and as a home medical equipment provider that is accredited in all 50 states in the United States with a significant patient, prescriber and provider reach. Our products are sold internationally through distributors and medical equipment companies outside of the United States and through direct patient and prescriber sales, as well as resellers and home medical equipment companies in the United States.

    We derive the majority of our revenue from the sale and rental of our Inogen One and Rove systems and related accessories to patients, insurance carriers, home healthcare providers, resellers, and distributors, including our private label partner. We sell multiple configurations of our Inogen One, Rove and Inogen At Home systems with various batteries, accessories, warranties, power cords, and language settings. Our goal is to design, build, and market oxygen solutions that redefine how long-term oxygen therapy is delivered.

    To accomplish this goal, we intend to:

    •
    Optimize our domestic direct-to-consumer sales and prescriber sales teams and increase productivity. We have a continued focus on the prescriber sales force initiative, which markets directly to physicians through a consistent cadence of contact, gaining the prescription at initiation and maximizing the number of months of billing for long-term oxygen treatment. Also, as part of our growth plans, we expect to continue to expand sales and rental revenue capacity by focusing on increased productivity driven by improved sales management discipline, insights-informed tools, and optimized patient lead generation.
    •
    Expand our domestic home medical equipment (HME) provider and reseller network. We have continued focus on our domestic business-to-business partnerships, including relationships with distributors, key accounts, resellers, our private label partner, and traditional HME providers. We offer patient-preferred, low total cost of ownership products to help providers convert their businesses to a non-delivery POC business model.
    •
    Increase international business-to-business adoption. Although our main growth opportunity remains POC adoption in the United States given what we still believe is a relatively low penetration rate, we believe there is a sizable international market opportunity, particularly in Europe where there is existing oxygen reimbursement for respiratory conditions. In order to take advantage of these international markets, we have partnered with distributors who serve those markets and key customers in them. We additionally have an Inogen base of operations for sales and customer service in the Netherlands, and use a contract manufacturer, Foxconn, located in the Czech Republic to support the majority of our European sales volumes.
    •
    Invest in our oxygen product offerings to develop innovative products and expand clinical evidence. We incurred $6.6 million and $5.3 million in the three months ended March 31, 2024 and 2023, respectively, in research and development expenses, and we intend to continue to make such investments in the foreseeable future.

    We launched the Inogen® Rove 6TM, our latest POC, in December 2022 in the EU and UK. We have also received U.S. Food and Drug Administration (FDA) 510(k) clearance for the Inogen® Rove 4TM . Inogen Rove 6 weighs 4.8 pounds and produces 1,260 ml per minute of oxygen output with very quiet operations at 37 dBA and long battery life at 6 hours and 15 minutes for a single battery and up to 12 hours and 45 minutes for a double battery, as well as improvements to provide ease-of-use and improvements to design in compliance to European Union medical device regulation (MDR) standards. The FDA clearance of Inogen Rove 6 was received June 30, 2023 and launched in the U.S. market in July 2023.

    The Inogen Rove 6 is the first POC with an 8-year expected service life. The 8-year expected service life also extends to the Inogen One G5® systems. We launched the Inogen One G5 in 2019. The Inogen One G5 is similar to the product specifications of the Inogen Rove 6. We estimate that the Inogen Rove 6 and Inogen One G5 are each suitable for over 90% of ambulatory long-term oxygen therapy patients based on our analysis of the patients who have contacted us and their clinical needs.

    24


     

    Inogen Connect, our connectivity platform on our Inogen One G4®, Inogen One G5, and Inogen Rove 6 products in the United States and Canada, is compatible with Apple and Android platforms and includes patient features such as purity status, battery life, product support functions, notification alerts, and remote software updates.

    We plan to also invest in clinical studies to evaluate expected improvements in clinical, economic and patient reported outcomes associated with the use of our products as part of our efforts to drive payor and prescriber advocacy for our products.

    •
    Expand our product offerings and indications for use. We are focused on expanding new products that drive benefits to patients, prescribers, and our customers with a clinically relevant pipeline. These products would include innovations that strengthen our offerings in chronic obstructive pulmonary disease, as well as future innovations that differentiate beyond devices to allow patients and clinicians to better manage respiratory disease with advanced POCs with digital health value added services, expansion of use to hypercapnia, shortness-of-breath, and to other related disease indications.

    Sales revenue

    Our future financial performance will be driven in part by the growth in sales of our POCs, Simeox airway clearance, and, to a lesser extent, sales of batteries, other accessories, and our Inogen At Home stationary oxygen concentrators. We plan to grow our system sales in the coming years through multiple strategies including: improving sales force productivity, hiring additional sales representatives directly, investing in consumer and physician awareness and advocacy through increased sales and marketing efforts, expanding our clinical evidence, expanding our sales infrastructure and efforts outside of the United States, expanding our business-to-business sales through key strategic partnerships, and enhancing our product offerings through additional product launches. While we believe HME providers are still in the process of converting their business model to a non-delivery model through the purchase of POCs, growth has been challenged due to HME restructuring efforts, lack of access to available credit, provider capital expenditure constraints, and risk of potential changes in reimbursement rates.

    Our direct-to-consumer sales processes involve numerous interactions with the individual patient, their physician and the physician’s staff, and includes an in-depth analysis and review of our product, the patient’s diagnosis and prescribed oxygen therapy, including procuring an oxygen prescription. The patient may consider whether to finance the product through an Inogen-approved third party or purchase the equipment. Product is not deployed until both the prescription and payment are secured. Once a full system is deployed, the patient has 30 calendar days to return the product. Approximately 6-11% of consumers who purchase a system return the system during this 30-day return period.

    Our business-to-business efforts are focused on selling to distributors, HME oxygen providers, our private label partner, and resellers who are based inside and outside of the United States. This process involves interactions with various key customer stakeholders including sales, purchasing, product testing, and clinical personnel. Businesses that have patient demand that can be met with our products place purchase orders to secure product deployment. This may be influenced based on outside factors, including the result of tender offerings, changes in insurance plan coverage or reimbursement rates, business restructuring activities toward a non-delivery model, capital constraints, mergers and acquisitions, and overall changes in the net oxygen therapy patient populations. As a result of these factors, product purchases can be subject to changes in demand by customers.

    We sold approximately 33,900 systems in the three months ended March 31, 2024 and 26,900 systems for the same period in 2023. The increase in the current period was primarily due to the result of increased demand from resellers. We continue to focus on optimizing profitability in our direct-to-consumer channel, driving sales productivity with an efficiently scaled sales organization.

    25


     

    Rental revenue

    Our rental process involves numerous interactions with the individual patient, their physician and the physician’s staff. The process includes an in-depth analysis and review of our product, the patient’s diagnosis and prescribed oxygen therapy, and their medical history to confirm the appropriateness of our product for the patient’s oxygen therapy and compliance with Medicare and private payor billing requirements, which often necessitates additional physician evaluation and/or testing for oxygen. Once the product is deployed, the patient receives instruction on product use and may receive a clinical titration from our licensed staff to confirm the product meets the patient’s medical oxygen needs prior to billing. As a result, the period of time from initial contact with a patient to billing can vary significantly and be up to one month or longer. CMS adopted additional changes to the administrative requirements to dispense and bill for oxygen therapy which may have reduced the administrative burden and increased patient access to our products.

    Rental revenue decreased in the three months ended March 31, 2024 compared to the three months ended March 31, 2023, primarily due to a higher rental revenue adjustments and lower average reimbursement rates per patient resulting from the change in mix of payors toward private insurance from Medicare. Medicare reimbursement rates for oxygen therapy have increased annually each January as they are subject to Consumer Price Index adjustments. We plan to add new rental patients on service in future periods through multiple strategies, including expanding our prescriber sales teams, expanding our direct-to-consumer marketing efforts, investing in patient and physician awareness and advocacy, expanding clinical evidence, and securing additional insurance contracts.

    A portion of the rental patient population operates in a capped rental period during which no additional reimbursement is allowed unless additional criteria are met. This capped period begins after month 36 and continues until month 60. The ratio of billable patients to total patients on service is critical to maintaining rental revenue growth as patients on service increase. Medicare has noted a certain percentage of beneficiaries, approximately 25%, based on their review of Medicare claims, reach the 36th month of eligible reimbursement and enter the post-36 month capped rental period. The percentage of capped patients may fluctuate over time as new patients come on service, patients come off service before and during the capped rental period, and existing patients enter the capped rental period.

    We had approximately 51,800 and 45,800 oxygen rental patients as of March 31, 2024 and March 31, 2023, respectively. Management focuses on patients on service as a leading indicator of likely future rental revenue; however, actual rental revenue recognized is subject to a variety of other factors, including billable patients as a percentage of patients on service, reimbursement levels by payor, patient location, the number of capped patients, write-offs for uncollectible balances, and rental revenue adjustments.

    Reimbursement

    We rely significantly on reimbursement from Medicare and private payors, including Medicare Advantage plans and Medicaid, for our rental revenue. For the three months ended March 31, 2024 and 2023, approximately 58.4% and 73.8%, respectively, of our rental revenue was derived from Medicare’s traditional fee-for-service reimbursement programs. For additional discussion of our reliance on third-party reimbursement and the impact of the recent Medicare reimbursement proposals, see the discussion in the subsection entitled "Third-Party Reimbursement" in Item 1 of our Annual Report on Form 10-K and the section entitled “Risk Factors” in our Annual Report on Form 10-K filed with the SEC on March 1, 2024.

    Basis of presentation

    The following describes the line items set forth in our consolidated statements of comprehensive loss.

    Revenue

    We classify our revenue in two main categories: sales revenue and rental revenue. There will be fluctuations in mix between business-to-business sales, direct-to-consumer sales, and rental revenue from period-to-period. Product selling prices and gross margins may fluctuate based on revenue channel mix, as we introduce new products, our product costs change, we have changes in purchase volumes, and as currency variations occur. Additionally, fluctuations in the channel mix could cause variability in our gross margins, as direct-to-consumer sales and rental revenue have higher margins than the business-to-business channels. Quarter-over-quarter results may vary due to seasonality in both the international and domestic markets, as discussed in Item 1. Seasonality and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on March 1, 2024.

    Sales revenue

    Our sales revenue is primarily derived from the sale of our Inogen Rove, Inogen One, and Inogen At Home systems in addition to our related accessories to individual consumers, our private label partner, HME providers, distributors, and resellers. Sales revenue is classified into two areas: business-to-business sales and direct-to-consumer sales. Generally, our direct-to-consumer sales have higher gross margins than our business-to-business sales.

    Our rental revenue is primarily derived from the rental of our Inogen One and Inogen At Home systems to patients through reimbursement from Medicare, private payors, and Medicaid, which typically also includes a patient responsibility component for patient co-insurance and deductibles. We expect that our rental revenue will be impacted by the number of our sales representatives, reimbursement rate changes, the level of and response from potential customers to direct-to-consumer marketing spend, product launches, the number of billable patients and denial rates, and other uncontrollable factors such as changes in the market and competition.

    Cost of revenue

    Cost of sales revenue

    Cost of sales revenue consists primarily of costs incurred in the production process, including component materials, assembly labor and overhead, warranty expense, provisions for slow-moving and obsolete inventory, rework, and delivery costs for items sold. Labor and overhead expenses consist primarily of personnel-related expenses, including wages, bonuses, benefits, and stock-based compensation for manufacturing, logistics, repair, manufacturing engineering, and quality assurance employees and temporary labor. Cost of sales revenue also includes manufacturing freight in, depreciation expense, facilities costs, and materials. Provisions for warranty obligations are included in cost of sales revenue and are provided for at the time of revenue recognition.

    The impact of supply chain disruptions began negatively impacting our cost of sales revenue starting in the third quarter of 2021 and is expected to have minimal impact throughout 2024. The supply chain constraints are primarily associated with semiconductor chips used in our batteries and printed circuit boards which are components of our POCs.

    For these reasons, we expect sales gross margin percentage to fluctuate over time based on the sales channel mix, product mix, and changes in average selling prices and manufacturing cost per unit.

    Cost of rental revenue

    Cost of rental revenue consists primarily of depreciation expense, consumable disposables, logistics costs, and service costs for rental patients, including rework costs, material, labor, and freight.

    Rental gross margin percentage could fluctuate due to changes in depreciation expense, cost to service and maintain the rental fleet as well as the percentage of billable patients as a percentage of patients on service.

    Operating expense

    Research and development

    Our research and development expense consists primarily of personnel-related expenses, including wages, bonuses, benefits, and stock-based compensation for research and development, engineering, and medical affairs employees. It also includes facility costs, laboratory supplies, product development materials, consulting fees, clinical studies costs, and testing costs for new product launches as well as enhancements to existing products. We have made substantial investments in research and development since our inception. Our research and development efforts have focused primarily on development and commercialization of new and existing products.

    We plan to continue to invest in research and development activities to stay at the forefront of patient preference in oxygen therapy, including significant investments in clinical research. We continue to invest in our engineering and technology teams to support our new and enhanced product research and development efforts and manufacturing improvements. We will also focus research and development efforts on broadening our product portfolio.

    Sales and marketing

    Our sales and marketing expense primarily supports our direct-to-consumer sales and rental strategy and consists mainly of personnel-related expenses, including wages, bonuses, commissions, benefits, and stock-based compensation for sales, marketing, customer service, rental intake, and clinical service employees. It also includes expenses for media and advertising, printing, informational kits, dues and fees, credit card/financing fees, recruiting, training, sales promotional activities, travel and entertainment expenses as well as allocated facilities costs.

    Going forward, our plan is to optimize our sales capacity while focusing on increased productivity, improved sales personnel and lead distribution systems, and improved training. We expect to continue to invest in sales and marketing by focusing on increased productivity driven by improved sales management discipline, insights-informed tools, and optimized patient lead generation as well as increasing our rental patient support infrastructure as our patient and customer base increases.

    General and administrative

    Our general and administrative expense consists primarily of personnel-related expenses, including wages, bonuses, benefits, and stock-based compensation for employees in our compliance, finance, medical billing, order intake, regulatory, legal, human resources, and information technology departments as well as facilities costs and board of directors’ expenses, including stock-based compensation. In addition, general and administrative expense includes professional services, such as legal, patent registration and defense costs, insurance, consulting and accounting services, including audit and tax services, and travel and entertainment expenses. General and administrative expense also includes one-time costs, such as restructuring, acquisition expenses, and changes in the fair value of the earnout liability.

    We expect general and administrative expense may increase in absolute dollars as we continue to invest in corporate infrastructure to support our growth including personnel-related expenses, professional services fees, and compliance costs associated with operating as a public company.

    Income taxes

    We account 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 our consolidated financial statements or tax returns. 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.

    We account for uncertainties in income tax 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 accounting for stock-based compensation will increase or decrease our effective tax rate based upon the difference between our stock-based compensation expense and the deductions taken on our U.S. tax return, which depends upon the stock price at the time of employee option exercise or award vesting. We recognize excess tax benefits or deficiencies on a discrete basis, and we anticipate our effective tax rate will vary from year-to-year depending on our stock price in each period.

    Sales revenue increased $7.2 million for the three months ended March 31, 2024 from the three months ended March 31, 2023, an increase of 12.9% from the comparable period. The increase was primarily attributable to higher international and domestic business-to-business sales. We sold approximately 33,900 oxygen systems during the three months ended March 31, 2024 compared to approximately 26,900 oxygen systems sold during the three months ended March 31, 2023, an increase of 26.0%.

    Rental revenue decreased $1.3 million for the three months ended March 31, 2024 from the three months ended March 31, 2023, or a decrease of 8.3% from the comparable period. The decrease in rental revenue was primarily related to higher rental revenue adjustments and a higher mix of lower private-payor reimbursement rates, partially offset by higher patients on service.

    Domestic business-to-business sales increased 31.3% for the three months ended March 31, 2024 compared to the three months ended March 31, 2023 primarily due to the result of increased demand from new customers and resellers.

    International business-to-business sales increased 37.2% for the three months ended March 31, 2024 compared to the three months ended March 31, 2023, primarily due to an increase in sales from our partners in Europe. In the three months ended March 31, 2024, sales in Europe as a percentage of total international sales revenue increased to 88.2% versus 81.8% from the comparative period in 2023.

    Domestic direct-to-consumer sales decreased 15.6% for the three months ended March 31, 2024 compared to the three months ended March 31, 2023, primarily driven by lower volume due to lower sales representative headcount, partially offset by increased average selling prices and increased unit volume per sales representative versus the comparative period in 2023.

    Domestic direct-to-consumer rentals decreased 8.3% for the three months ended March 31, 2024 compared to the three months ended March 31, 2023, primarily related to higher rental revenue adjustments and a higher mix of lower private-payor reimbursement rates.

    Cost of sales revenue increased $1.3 million for the three months ended March 31, 2024 from the three months ended March 31, 2023, an increase of 3.8% from the comparable period, due primarily to an increase in the number of systems sold and partially offset by lower premiums paid for components and lower labor and overhead costs. The first quarter of 2024 included less than $0.1 million of material cost premiums associated with open-market purchases of semiconductor chips used in our batteries and POCs compared to $4.5 million in the first quarter of 2023.

    Cost of rental revenue increased $0.9 million for the three months ended March 31, 2024 from the three months ended March 31, 2023, an increase of 12.7% from the comparable period. The increase in cost of rental revenue was primarily attributable to an increase in total patients on service, which led to increased service and logistics costs. Cost of rental revenue included $3.2 million of rental asset depreciation for the three months ended March 31, 2024 compared to $3.1 million for the three months ended March 31, 2023.

    Gross margin on sales revenue increased to 44.1% for the three months ended March 31, 2024 from 39.2% for the three months ended March 31, 2023. The increase was primarily due to lower material cost premiums associated with open-market purchases of semiconductor chips used in our batteries and POCs, partially offset by a change in sales mix towards increased business-to-business sales. Total worldwide business-to-business sales revenue accounted for 67.4% of total sales revenue in the three months ended March 31, 2024 versus 56.5% in the three months ended March 31, 2023.

    Gross margin on rental revenue decreased to 43.7% for the three months ended March 31, 2024 from 54.1% for the three months ended March 31, 2023, primarily due to lower net revenue per rental patient as a result of a decrease in the percentage of patients billed compared to total patients on service, a higher mix shift of private-payor reimbursement and higher rental revenue adjustments.

    Net loss decreased $5.8 million for the three months ended March 31, 2024 from the three months ended March 31, 2023, or a decrease of 28.4% from the comparable period. The decrease in net loss was primarily related to an increase in sales revenue and lower operating expense and material cost premiums.

    Liquidity and capital resources

    As of March 31, 2024, we had cash and cash equivalents of $107.4 million, which consisted of highly liquid investments with a maturity of three months or less. In addition, we held marketable securities of $12.4 million, which had maturities of greater than three months. For the three months ended March 31, 2024 and 2023, we received $0.4 million and $1.0 million, respectively, in proceeds related to stock option exercises and our employee stock purchase plan.

    Our principal uses of cash for liquidity and capital resources in the three months ended March 31, 2024 consisted of operating activities of $4.7 million as well as cash used in investing activities of $9.4 million for net purchases of marketable securities, and $4.1 million for additional rental equipment and other property, plant and equipment.

    We believe that our current cash, cash equivalents, and marketable securities and the cash to be generated from expected product sales and rentals will be sufficient to meet our projected operating and investing requirements for at least the next twelve months. However, our liquidity assumptions may prove to be incorrect, and we could utilize our available financial resources sooner than we currently expect. Our future funding requirements will depend on many factors, including market acceptance of our products; the cost of our research and development activities; payments from customers; the cost, timing, and outcome of litigation or disputes involving intellectual property rights, our products, employee relations, cyber security incidents, or otherwise; the cost and timing of acquisitions and integration thereof; the cost and timing of regulatory clearances or approvals; the cost and timing of establishing additional sales, marketing, and distribution capabilities; and the effect of competing technological and market developments. In the future, we may acquire businesses or technologies from third parties, and we may decide to raise additional capital through debt or equity financing to the extent we believe this is necessary to successfully complete these acquisitions. Our future capital requirements will also depend on many additional factors, including those set forth in the risk factors included in Item 1A. "Risk Factors" in our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q filed with the SEC.

    If we require additional funds in the future, we may not be able to obtain such funds on acceptable terms, or at all. In the future, we may also attempt to raise additional capital through the sale of equity securities or through equity-linked or debt financing arrangements. If we raise additional funds by issuing equity or equity-linked securities, the ownership of our existing stockholders will be diluted. If we raise additional financing by the incurrence of indebtedness, we will be subject to increased fixed payment obligations and could also be subject to restrictive covenants, such as limitations on our ability to incur additional debt, and other operating restrictions that could adversely impact our ability to conduct our business. Any future indebtedness we incur may result in terms that could be unfavorable to equity investors. There can be no assurances that we will be able to raise additional capital, which would adversely affect our ability to achieve our business objectives. In addition, if our operating performance during the next twelve months is below our expectations, our liquidity and ability to operate our business could be adversely affected.

    Operating activities

    Historically, we derive operating cash flows from cash collected from the sales and rental of our products and services. These cash flows received are partially offset by our use of cash for operating expenses to support the growth of our business.

    Net cash used in operating activities for the three months ended March 31, 2024 consisted primarily of our net loss of $14.6 million, partially offset by non-cash adjustment items such as depreciation of equipment and leasehold improvements and amortization of intangibles of $5.3 million, stock-based compensation expense of $2.4 million, provision for sales returns and doubtful accounts of $2.2 million, net loss on disposal of rental assets and other assets of $1.2 million, and change in fair value of earnout liability of $0.6 million. The net changes in operating assets and liabilities resulted in a net decrease in cash of $1.5 million.

    Net cash used in operating activities for the three months ended March 31, 2023 consisted primarily of our net loss of $20.3 million, partially offset by non-cash adjustment items such as depreciation of equipment and leasehold improvements and amortization of intangibles of $4.1 million, stock-based compensation expense of $3.4 million, provision for sales returns and doubtful accounts of $2.3 million, net loss on disposal of rental assets and other assets of $1.1 million, and provision for inventory obsolescence and other inventory losses of $0.6 million. The net changes in operating assets and liabilities resulted in a net increase in cash of $2.6 million.

    Investing activities

    Net cash used in investing activities generally includes the production and purchase of rental assets, property, plant and equipment, acquisitions, and intangibles to support our expanding business as well as maturities (purchases) of marketable securities.

    For the three months ended March 31, 2024, we invested $12.4 million in the purchase of marketable securities, $4.1 million in the production and purchase of rental assets and other property and equipment, partially offset by $3.0 million we received from maturities of marketable securities.

    For the three months ended March 31, 2023, we invested $10.4 million in the purchase of marketable securities and $6.8 million in the production and purchase of rental assets and other property and equipment.

    We expend significant manufacturing and production expense in connection with the development and production of our oxygen concentrator products and, in connection with our rental business, we incur expense in the deployment and maintenance of rental equipment to our patients. Investments will continue to be required in order to grow our sales and rental revenue and continue to supply and replace rental equipment to our rental patients on service.

    Financing activities

    Historically, we have funded our operations through our sales and rental revenue and the issuance of preferred and common stock.

    For the three months ended March 31, 2024, net cash provided by financing activities consisted of $0.4 million from the proceeds received from purchases under our employee stock purchase program, partially offset by the payment of employment taxes related to the vesting of restricted stock units of $0.1 million.

    For the three months ended March 31, 2023, net cash provided by financing activities consisted of $1.0 million from the proceeds received from stock options that were exercised and purchases under our employee stock purchase program, partially offset by the payment of employment taxes related to the vesting of restricted stock awards and restricted stock units of $0.5 million.

    Sources of funds

    Our net cash used in operating activities in the three months ended March 31, 2024 was $4.7 million compared to net cash used in operating activities of $6.3 million in the three months ended March 31, 2023. As of March 31, 2024, we had cash and cash equivalents of $107.4 million and marketable securities of $12.4 million.

    Use of funds

    Our principal uses of cash are funding our new rental asset deployments and other capital purchases, operations, and other working capital requirements and, from time-to-time, the acquisition of businesses. Over the past several years our cash flows from customer collections have remained consistent and our annual cash provided by operating activities has generally been a significant source of capital to the business.

    32


     

    We may need to raise additional funds to support our investing operations, and such funding may not be available to us on acceptable terms, or at all. If we are unable to raise additional funds when needed, our operations and ability to execute our business strategy could be adversely affected. We may seek to raise additional funds through equity, equity-linked or debt financings. If we raise additional funds through the incurrence of indebtedness, such indebtedness would have rights that are senior to holders of our equity securities and could contain covenants that restrict our operations. Any additional equity financing may be dilutive to our stockholders.

    Non-GAAP financial measures

    EBITDA and Adjusted EBITDA are financial measures that are not calculated in accordance with U.S. GAAP. We define EBITDA as net loss excluding interest income, interest expense, taxes and depreciation and amortization. Adjusted EBITDA also excludes stock-based compensation, change in fair value of earnout liability, acquisition-related expenses, and restructuring-related and other charges. Below, we have provided a reconciliation of EBITDA and Adjusted EBITDA to our net loss, the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP. EBITDA and Adjusted EBITDA should not be considered alternatives to net loss or any other measure of financial performance calculated and presented in accordance with U.S. GAAP. Our EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures of other organizations because other organizations may not calculate EBITDA and Adjusted EBITDA in the same manner as we calculate these measures.

    We include EBITDA and Adjusted EBITDA in this Quarterly Report on Form 10-Q because they are important measures upon which our management assesses our operating performance. We use EBITDA and Adjusted EBITDA as key performance measures because we believe they facilitate operating performance comparisons from period-to-period by excluding potential differences primarily caused by variations in capital structures, tax positions, the impact of depreciation and amortization expense on our fixed assets and intangible assets, the impact of stock-based compensation expense, the impact of the change in fair value of the earnout liability, the impact of acquisition-related expenses, the impact of restructuring-related costs, and impairment charges. Because EBITDA and Adjusted EBITDA facilitate internal comparisons of our historical operating performance on a more consistent basis, we also use EBITDA and Adjusted EBITDA for business planning purposes, to incentivize and compensate our management personnel, and in evaluating acquisition opportunities. In addition, we believe EBITDA and Adjusted EBITDA and similar measures are widely used by investors, securities analysts, ratings agencies, and other parties in evaluating companies in our industry as a measure of financial performance and debt-service capabilities.

    Our uses of EBITDA and Adjusted EBITDA have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results as reported under U.S. GAAP. Some of these limitations are:

    •
    EBITDA and Adjusted EBITDA do not reflect our cash expenditures for capital equipment or other contractual commitments;
    •
    although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and EBITDA and Adjusted EBITDA do not reflect capital expenditure requirements for such replacements;
    •
    EBITDA and Adjusted EBITDA do not reflect changes in, or cash requirements for, our working capital needs;
    •
    Adjusted EBITDA does not include changes in fair value of earnout liability related to our acquisitions;
    •
    Adjusted EBITDA does not include acquisition-related expenses, whether the acquisition was consummated or not pursued;
    •
    Adjusted EBITDA does not include costs associated with workforce reductions and associated costs and other restructuring-related activities; and
    •
    other companies, including companies in our industry, may calculate EBITDA and Adjusted EBITDA measures differently, which reduces their usefulness as a comparative measure.

    In evaluating EBITDA and Adjusted EBITDA, we anticipate that in the future we will incur expenses within these categories similar to this presentation. Our presentation of EBITDA and Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by certain expenses. When evaluating our financial results, EBITDA and Adjusted EBITDA should be considered alongside other financial performance measures, including U.S. GAAP results.

    Item 3. Quantitative and Qualitative Disclosures About Market Risk

    We are exposed to various market risks, including fluctuation in foreign currency exchange rates and interest rates. Market risk is the potential loss arising from adverse changes in market rates and prices. We do not hold or issue financial instruments for trading purposes.

    Foreign currency exchange risk

    The principal market risk we face is foreign currency exchange risk. The majority of our revenue is denominated in U.S. dollars while the majority of our European sales are denominated in Euros. Our results of operations, certain balance sheet balances and cash flows are, therefore, subject to fluctuations due to changes in foreign currency exchange rates. The volatility of exchange rates depends on many factors that we cannot forecast with reliable accuracy. We have experienced and will continue to experience fluctuations in our net income or loss as a result of transaction gains or losses related to revaluing certain current asset and current liability balances that are denominated in currencies other than the functional currency in which they are recorded. The effect of a 10% adverse change in exchange rates on foreign denominated cash, receivables and payables as of March 31, 2024 would not have had a material effect on our financial position, results of operations or cash flows. As our operations in countries outside of the United States grow, our results of operations and cash flows will be subject to fluctuations due to changes in foreign currency exchange rates, which could harm our business in the future.

    We began entering into foreign exchange forward contracts to protect our forecasted U.S. dollar-equivalent earnings from adverse changes in foreign currency exchange rates. These hedging contracts reduce, but will not entirely eliminate, the impact of adverse currency exchange rate movements on revenue, cash, receivables, and payables. We performed a sensitivity analysis assuming a hypothetical 10% adverse movement in foreign exchange rates to the hedging contracts and the underlying exposures described above. As of March 31, 2024, the analysis indicated that these hypothetical market movements would not have a material effect on our financial position, results of operations or cash flows. We estimate prior to any hedging activity that a 10% adverse change in exchange rates on our foreign denominated sales would have resulted in a $2.1 million decline in revenue for the three months ended March 31, 2024. We designate these forward contracts as cash flow hedges for accounting purposes. The fair value of the forward contract is separated into intrinsic and time values. The fair value of forward currency-exchange contracts is sensitive to changes in currency exchange rates. Changes in the time value are coded in other income (expense), net. Changes in the intrinsic value are recorded as a component of accumulated other comprehensive loss and subsequently reclassified into revenue to offset the hedged exposures as they occur.

    Interest rate fluctuation risk

    We had cash and cash equivalents of $107.4 million as of March 31, 2024, which consisted of highly liquid investments with a maturity of three months or less, and $12.4 million of marketable securities with maturity dates of greater than three months. The primary goals of our investment policy are liquidity and capital preservation. We do not enter into investments for trading or speculative purposes. We believe that we do not have any material exposure to changes in the fair value of these assets as a result of changes in interest rates due to the short-term nature of our cash and cash equivalents. Declines in interest rates, however, would reduce future investment income. We considered the historical volatility of short-term interest rates and determined that it was reasonably possible that an adverse change of 100 basis points could be experienced in the near term. A hypothetical 1.00% (100 basis points) increase in interest rates would not have materially impacted the fair value of our marketable securities as of March 31, 2024 and March 31, 2023. If overall interest rates had increased or decreased by 1.00% (100 basis points), our interest income would not have been materially affected during the three months ended March 31, 2024 or March 31, 2023.

    Item 4. Controls 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 Securities Exchange Act of 1934, as amended (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 March 31, 2024. Based upon the evaluation described above, our Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2024, our disclosure controls and procedures were effective at the reasonable assurance level.

    Changes in internal control 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.

    Part II. OTHER INFORMATION

     

    Item 1. Legal Proceedings

    We are party to various legal proceedings and investigations arising in the normal course of business. We carry insurance, subject to specified deductibles under the policies, to protect against losses from certain types of legal claims. At this time, we do not anticipate that any of these other proceedings arising in the normal course of business will have a material adverse effect on our business. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

    Item 1A. Risk Factors

    The significant factors known to us that could materially adversely affect our business, financial condition, or operating results are described in the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on March 1, 2024 and below. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. As of the date of this Quarterly Report on Form 10-Q, there have been no material changes from the risk factors previously disclosed in our 2023 Annual Report on Form 10-K filed with the SEC on March 1, 2024, which are incorporated by reference herein, except as disclosed below.

    We and our vendors and service providers rely on information technology networks and systems, and if we are unable to protect against service interruptions, data corruption, cybersecurity risks, data security incidents and/or network security breaches, our operations could be disrupted, and our business could be negatively affected.

    We rely on information technology networks and systems, certain of which are operated by third parties on which we rely, to process, transmit and store electronic, customer, operational, compliance, and financial information; to coordinate and otherwise operate our business; and to communicate within our company and with customers, suppliers, partners and other third parties. These information technology networks and systems may be susceptible to damage, disruptions or shutdowns, hardware or software failures, power outages, computer viruses, ransomware, and other malware, cybersecurity risks, data security incidents, telecommunication failures, user errors or catastrophic events. Like other companies, we have experienced data security incidents before.

    We have incurred remedial, legal and other costs in connection with this incident. We have insurance coverage in place for certain potential liabilities and costs relating to service interruptions, data corruption, cybersecurity risks, data security incidents and/or network security breaches, but this insurance is limited in amount, subject to a deductible, and may not be adequate to cover us for all costs arising from these incidents.

    If our information technology networks and systems or those provided by our third-party service providers and vendors suffer unauthorized access, severe damage, disruption or shutdown, and our business does not effectively identify or resolve the issues in a timely manner, our operations could be disrupted, we could be subject to regulatory and consumer lawsuits and other proceedings and our business could be negatively affected. For example, Change Healthcare, a division of UnitedHealthcare, experienced a cyberattack in late February 2024 that caused connection issues with our third-party service provider and a delay in rental revenue collections. In addition, cybersecurity risks and data security incidents could lead to potential unauthorized access to or acquisition of confidential information (including personally identifiable information and protected health information), and data loss, corruption, unavailability, or other unauthorized processing. There is no assurance that we will not experience service interruptions, security breaches, cybersecurity risks and data security incidents, or other information technology failures, whether suffered by us or third parties on which we rely, in the future.

    Due to the COVID-19 pandemic and related public health emergency, we allowed an increased number of employees to work remotely, and we continue to do so and expect that this hybrid model of work will continue. As a result, we may have increased cybersecurity or data security risks, due to increased use of home wi-fi networks and virtual private networks, as well as increased disbursement of physical machines. While we implement IT controls to reduce the risk of a cybersecurity and data security breach, there is no guarantee that these measures will be adequate to safeguard all systems with an increased number of employees working remotely.

    The methods used to obtain unauthorized access, disable or degrade service or sabotage systems are constantly evolving and may be difficult to anticipate or to detect for long periods of time. As a result of these types of risks and attacks, we have implemented and periodically review and update systems, processes, and procedures to protect against unauthorized access to or use of data and to prevent data loss. For example, we have increased the security of our systems by requiring all email users to change their passwords following our recent data security incident and sooner than they would have otherwise been required to. We also implemented multi-factor authentication for remote email access and have taken additional steps to further limit access to our systems. However, the ever-evolving threats mean we and our third-party service providers and vendors must continually evaluate and adapt our respective systems and processes and overall security environment. There is no guarantee that these measures will be adequate to safeguard against all data security breaches, system compromises or misuses of data.

    37


     

    The compromise of our technology systems resulting in the loss, disclosure, misappropriation of, or access to, customers’, employees’ or business partners’ information or failure to comply with regulatory or contractual obligations with respect to such information, or the perception that any of these has occurred, could result in legal claims and proceedings, initiated by private parties, investigations or other proceedings by regulatory authorities, and liability or regulatory penalties, disruption to our operations and damage to our reputation, any or all of which could adversely affect our business. The costs to remediate breaches and similar system compromises that do occur could adversely affect our results of operations.

    Any new laws, regulations, other legal obligations or industry standards, or any changed interpretation of existing laws, regulations or other standards may require us to incur additional costs and restrict our business operations. For example, many jurisdictions have enacted laws requiring companies to notify individuals of data security breaches involving certain types of personal data. These mandatory disclosures regarding a security breach could result in negative publicity to us, which may cause our customers to lose confidence in the effectiveness of our data security measures which could adversely affect our business, financial condition and results of operations.
