Accounting Policies [Abstract]
Nature of Business and Significant Accounting Policies	Nature of Business and Significant Accounting Policies Inseego Corp. (the “Company”, “Inseego”, “We” or “Our”) is a leader in the design and development of fixed and mobile wireless products as well as cloud solutions for businesses, consumers, and governments around the globe. Our products and solutions are powered by our key wireless innovations in mobile and FWA technologies, including a suite of products employing the 5G NR standards, and purpose-built SaaS cloud platforms. Inseego is a Delaware corporation formed in 2016 and is the successor to Novatel Wireless, Inc., a Delaware corporation formed in 1996, resulting from an internal reorganization that was completed in November 2016. The Company’s principal executive office is located at 9710 Scranton Road, Suite 200, San Diego, CA 92121. The Company’s corporate offices are also located at 9710 Scranton Road, Suite 200, San Diego CA 92121 and its sales and engineering offices are located throughout the world. Inseego’s common stock trades on the NASDAQ Global Select Market under the trading symbol “INSG.” Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Basis of presentation The consolidated financial statements of Inseego Corp. present information in accordance with generally accepted accounting principles in the U.S. (“GAAP”), have been prepared pursuant to the rules and regulations of the SEC and, in the opinion of management, present fairly the consolidated financial position, results of operations and cash flows of the Company and its wholly-owned subsidiaries for the periods presented. Reclassifications Certain amounts recorded in the prior period consolidated financial statements have been reclassified to conform to the current period financial statement presentation. These reclassifications had no effect on previously reported operating results. During 2023 the Company has reclassified revenue on the Consolidated Statement of Operations. Historically, the Company classified revenues from products and services into two categories, IoT & Mobile Solutions and Enterprise SaaS Solutions. The Company is now classifying revenues from products and services into the following two categories: Product Revenue, which consists of our Mobile Solutions and Fixed Wireless Access Solutions, and Services and Other. See Revenue Recognition below for a description of these groupings. Additionally, during 2023 the Company reclassified all depreciation and amortization expense previously recorded in the operating expense line items of research and development, sales and marketing, and general and administrative expenses on the Consolidated Statement of Operations into a separate line labeled Depreciation and amortization. All prior periods have been reclassified to conform to the current period presentation for these changes. Reverse Stock Split On January 24, 2024, the Company completed a 1-for-10 reverse stock split of its issued and outstanding common stock (the “Reverse Stock Split”). As a result of the Reverse Stock Split, each share of common stock issued and outstanding immediately prior to January 24th were automatically converted into one-tenth (1/10) of a share of common stock. The Reverse Stock Split affected all common stockholders uniformly and did not alter any stockholder's percentage interest in the Company's equity, except to the extent that the Reverse Stock Split would result in a stockholder owning a fractional share. No fractional shares were issued in connection with the Reverse Stock Split. Stockholders who otherwise would be entitled to receive a fractional share instead were entitled to receive cash in lieu of such fractional share. The Reverse Stock Split did not change the par value of the common stock or the authorized number of shares of common stock. All outstanding convertible notes entitling their holders to purchase or obtain or convert into shares of our common stock were adjusted, as required by the terms of these securities. All common share and per-share amounts in this Form 10-K have been retroactively restated to reflect the effect of the Reverse Stock Split. Segment Information The Company has one reportable segment. The Chief Executive Officer, who is also the Chief Operating Decision Maker, does not manage any part of the Company separately, and the allocation of resources and assessment of performance is based solely on the Company’s consolidated operations and financial results. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent liabilities. Actual results could differ materially from these estimates. Estimates are assessed each period and updated to reflect current information. Significant estimates include revenue recognition, capitalized software costs, allowance for credit losses, provision for excess and obsolete inventory, accrued liabilities related to our contract manufacturers, valuation of tangible and intangible long-lived assets, valuation of goodwill, valuation of derivatives, accruals relating to litigation, income taxes and share-based compensation expense. Risks and Uncertainties We may be affected by various macroeconomic factors and the current and future conditions in the global financial markets. The global credit and financial markets have recently experienced volatility and disruptions, including diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, rising interest rates, inflation, increases in unemployment rates and uncertainty about economic stability. The inflationary pressures impacting the global supply chain could potentially increase the cost of revenues in the current and future years. The ongoing inflation challenges could adversely impact future revenues, gross margins and financial results. Furthermore, a global semiconductor supply shortage continues to have wide-ranging impacts across the technology industry. While the shortage has not materially impacted the Company’s operations and financial results, it may negatively impact the Company’s customers and the supply of materials needed for testing and production timeline. The Company’s suppliers, contract manufacturers, and customers are all taking actions to reduce the impact of the semiconductor shortage; however, if the shortage persists, the impact on operations and financial results could be material. Liquidity As of December 31, 2023, the Company had available cash and cash equivalents totaling $7.5 million, working capital of $2.3 million, and $3.2 million of availability to borrow under its secured asset-backed Credit Facility (as defined below). The Company has a history of operating and net losses and overall usage of cash from operating and investing activities. The Company’s management believes that its cash and cash equivalents on-hand, together with anticipated cash flows from operations, expected availability under its secured asset-backed Credit Facility, and anticipated savings from ongoing cost reduction efforts, will be sufficient to meet its cash flow needs for the next twelve months from the filing date of this report. The Company’s ability to attain profitable operations and generate positive cash flow is dependent upon achieving a level and mix of revenues adequate to support its evolving cost structure. If events or circumstances occur such that the Company does not meet its operating plan as expected, or if the Company becomes obligated to pay unforeseen expenditures as a result of potential litigation or otherwise, the Company may be required to raise capital, reduce planned research and development activities, incur additional restructuring charges or reduce other operating expenses and capital expenditures, which could have an adverse impact on the Company’s ability to achieve its intended business objectives. The Company’s Credit Facility has a maturity date of December 31, 2024. The Company’s convertible 2025 Notes (as defined below) have a principal balance of $161.9 million and matures on May 1, 2025. The Company’s intention is to restructure or refinance the Credit Facility and the 2025 Notes, however there can be no assurance that any required or desired restructuring or financing will be available on terms favorable to the Company, or at all. See Note 5 – Debt for more information on the Credit Facility and the 2025 Notes. Cash, Cash Equivalents, and Restricted Cash Cash and cash equivalents include highly liquid investments with original maturities of three months or less. The Company’s cash and cash equivalents are generally held with large financial institutions worldwide to reduce the amount of exposure to credit risk. Cash and cash equivalents are recorded at market value, which approximates cost. There are no cash equivalents as of December 31, 2023 or December 31, 2022. Gains and losses associated with the Company’s foreign currency denominated demand deposits are recorded as a component of other income, net, in the consolidated statements of operations. Restricted cash held in escrow as of December 31, 2021 was released during 2022 and we no longer have any restricted cash on our balance sheet as of December 31, 2023 and December 31, 2022. Revenue Recognition The Company’s products and services primarily include intelligent mobile hotspots, wireless routers for IoT applications, USB modems, integrated telematics and mobile tracking hardware devices, which are supported by applications software and cloud services designed to enable customers to easily analyze data insights and configure and manage their hardware. The Company classifies its revenues from the sale of its products and services into two categories, Product Revenue, which consists of our Mobile Solutions and Fixed Wireless Access Solutions, and Services and Other. See geographic disaggregation information in Note 12 – Geographic Information and Concentrations of Risk . Mobile solutions: Our Mobile wireless product portfolio consists of intelligent mobile broadband solutions, HD quality VoLTE products, 4G mobile solutions and an advanced 5G portfolio of mobile products. Our mobile broadband solutions, sold under the MiFi brand, are actively used by millions of end users annually to provide secure and convenient high-speed access to corporate, public and personal information through the Internet and enterprise networks. Our mobile portfolio includes cloud offerings with Inseego Connect for device management, and 5G SD EDGE for secure networking enabling corporate managed mobile remote workforce. Fixed wireless access solutions: O ur Fixed Wireless Solutions product portfolio consists of indoor, outdoor and industrial wireless broadband solutions. Our Fixed Wireless solutions, sold under the Wavemaker and Skyus brands, are sold by wireless operators such as T-Mobile, U.S. Cellular and Verizon Wireless along with distribution and channel partners. Services and other: Services and other primarily consists of various subscription offerings within the Company’s telematics platforms, which provide fleet vehicle, aviation ground vehicle and asset tracking and performance information, and other telematics applications; services performed under our Inseego Subscribe SaaS application, which provides managed the selection, deployment, and spend of customers’ wireless assets; and non-recurring engineering services provided to our customers. Revenue Recognition Criteria The Company follows Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) (as amended, “ASC 606”), which provides guidance on recognizing revenue, including a five-step model to determine when revenue recognition is appropriate. The standard requires that an entity recognize revenue to depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company recognizes revenue upon transfer of control of products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company determines revenue recognition according to the following five steps: (i) identification of the contract, or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when, or as, performance obligations are satisfied. Substantially all of our product revenues are recognized at a point in time, while substantially all of our service and other revenues are recognized over time. Customer Contracts The Company routinely enters into a variety of agreements with customers, including quality agreements, pricing agreements and master supply agreements which outline the general commercial terms and conditions under which the Company does business with a specific customer, including shipping terms and pricing for the products and services that the Company offers. The Company also sells to some customers solely based on purchase orders. The Company has concluded, for the vast majority of its revenues, that its contracts with customers are either a purchase order or the combination of a purchase order with a master supply agreement. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Performance Obligations The Company’s performance obligations are established when a customer submits a purchase order notification (in writing, electronically or verbally) for goods and services, and the Company accepts the order. The Company identifies performance obligations as the delivery of the requested product or service in appropriate quantities and to the location specified in the customer’s contract and/or purchase order. The Company generally recognizes revenue upon the satisfaction of these criteria when control of the product or service has been transferred to the customer at which time the Company has an unconditional right to receive payment. The Company’s prices are fixed and have no history of being affected by contingent events that could impact the transaction price. The Company does not offer price concessions and does not accept payment that is less than the price stated upon acceptance of a customer purchase order. The Company enters into contracts that may include various combinations of products and services which are generally capable of being distinct and accounted for as separate performance obligations. Hardware. Hardware revenue from the sale of the Company’s devices is recognized when the Company transfers control to the customer, typically at the time when the product is delivered, shipped or installed, at which time, title passes to the customer and there are no further performance obligations with regards to the hardware device. The Company also considered the performance obligations in its customer master supply agreements and determined that, for the majority of its revenue, the Company generally satisfies performance obligations at a point in time upon delivery of the product to the customer. Maintenance and support services revenue. Periodically, the Company sells separately-priced warranty contracts that extend beyond the Company’s base warranty period. The separately priced service contracts range from 12 to 36 months. The Company typically receives payment at the inception of the contract and recognizes revenue as earned on a straight-line basis over the term of the contract. The Company’s estimated allowances for product warranties can vary from actual results and the Company may have to record additional charges to cost of revenue. Within cost of revenue, the Company records an estimate to reflect its standard warranty obligation to end users to provide for replacement of a defective product. The standard obligation period for most regions is 12 months. Factors that affect the warranty obligation include product failure rates, material usage, and service delivery costs incurred in correcting product failures. SaaS and other services. SaaS subscription revenue is recognized over time on a ratable basis over the contract term beginning on the date that its service is made available to the customer. Subscription periods range from monthly to multi-year, with the majority of contracts being one Our telematics services include devices which collect and transmit information from vehicles or other assets. The Company’s customers have an option to purchase the monitoring device or lease it over the term of the contract. If the customer purchases the hardware device, the Company recognizes the revenue at a point in time as discussed above. Because the Company’s rental asset contracts qualify as operating leases under Accounting Standards Codification (“ASC”) 842, Leases , and the contracts also include services to operate and maintain the underlying asset, the Company has elected to combine the lease and non-lease components because the service is the predominant element in the eyes of the customer and the pattern of service delivery is the same for both elements. The Company recognizes revenue ratably over time throughout the term of the contract. Professional services revenue. From time to time, the Company enters into special engineering design service agreements. Revenues from engineering design services are designed to meet specifications of a particular product, and therefore do not create an asset with an alternative use. The Company recognizes revenue based on the achievement of certain applicable milestones and the amount of payment the Company believes it is entitled to at the time. Multiple performance obligations. The Company’s contracts with customers may include commitments to transfer multiple products and services to a customer. When hardware, software and services are sold in various combinations, judgment is required to determine whether each performance obligation is considered distinct and accounted for separately, or not distinct and accounted for together with other performance obligations. The Company considered the performance obligations in its customer master supply agreements and determined that, for the majority of its revenue, the Company generally satisfies performance obligations at a point in time upon delivery of the product to the customer. In instances where the software elements included within hardware for various products are considered to be functioning together with non-software elements to provide the tangible product’s essential functionality, these arrangements are accounted for as a single distinct performance obligation. Judgment is required to determine the stand-alone selling price (“SSP”) for each distinct performance obligation. When available, the Company uses observable inputs to determine SSP. In instances where SSP is not directly observable, such as when the Company does not sell the product or service separately, it determines the SSP based on a cost-plus model as market and other observable inputs are seldom present based on the proprietary nature of the Company’s products. Contract Assets The Company capitalizes sales commissions earned by its sales force as contract acquisition costs if such costs are significant and both incremental and recoverable. Any capitalized sales commissions are either deferred and amortized over a period of benefit exceeding one year or are expensed as incurred if the period of benefit is one year or less. There were no contract assets related to customer acquisition costs as of December 31, 2023 or 2022 since the Company’s customer contracts are predominantly hardware sales that are immediately recognized as revenue upon either shipment or delivery, and therefore the related contract acquisition costs are also immediately recognized. Sales commissions are included in sales and marketing expense as incurred. Sales commissions associated with SaaS offerings are not material. Contract Liabilities Timing of revenue recognition may differ from the timing of invoicing to customers. If customers are invoiced for subscription services in advance of the service period, then deferred revenue is recorded. Contract liabilities are also recorded when the Company collects payments in advance of performing the services. As of December 31, 2023 and 2022, the Company had contract liabilities comprised of $5.6 million and $5.1 million of short-term deferred revenue included within accrued expenses and other current liabilities and $1.7 million and $0.6 million of long-term deferred revenue included within other long-term liabilities on the consolidated balance sheets, respectively. Cost of Revenues Cost of revenues includes the costs associated with the manufacturing of our portfolio of hardware devices, as well as direct personnel costs for employees and contractors, depreciation and amortization, and other period adjustments related to costs of inventories sold or for sale or use in manufacturing. Shipping and Handling Charges Fees charged to customers for shipping and handling of products are included in product revenues, and costs for shipping and handling of products are included as a component of sales and marketing expense. Shipping and handling costs were approximately $1.0 million and $2.3 million for the years ended December 31, 2023 and December 31, 2022, respectively. Taxes Collected from Customers Taxes collected on the value of transaction revenue are excluded from product and services revenues and cost of sales and are accrued in current liabilities until remitted to governmental authorities. Accounts Receivable and Allowance for Expected Credit Losses Accounts receivable are customer obligations generally due under normal trade terms for the industry. Credit terms are granted and periodically revised based on evaluations of the customer’s financial condition. The Company performs ongoing credit evaluations of its customers. The Company’s payment terms are generally net 30 days from invoice date and could go up to 90 days for large carrier customers. The Company recognizes an allowance for credit losses at the time a receivable is recorded based on its estimate of expected credit losses and adjusts this estimate over the life of the receivable as needed. The Company evaluates the aggregation and risk characteristics of a receivable pool and develops loss rates that reflect historical collections, current forecasts of future economic conditions over the time horizon the Company is exposed to credit risk, and payment terms or conditions that may materially affect future forecasts. As needed, amounts are written-off when determined to be uncollectible. As of December 31, 2023 and 2022, the Company reported $22.6 million and $25.3 million, respectively, of accounts receivable, net of allowances of $1.1 million and $0.5 million, respectively. Inventories and Provision for Excess and Obsolete Inventory Inventories are stated at the lower of cost (first-in, first-out method) or net realizable value. Inbound shipping and handling costs are classified as a component of cost of revenues in the consolidated statements of operations. The Company reviews the components of its inventory and its inventory purchase commitments on a regular basis for excess and obsolete inventory based on estimated future usage and sales. Write-downs in inventory value or losses on inventory purchase commitments depend on various items, including factors related to customer demand, economic and competitive conditions, technological advances or new product introductions by the Company or its customers that vary from its current expectations. Whenever inventory is written down, a new cost basis is established and the inventory is not subsequently written up if market conditions improve. Intangible Assets other than Goodwill Intangible assets include purchased finite-lived and indefinite-lived intangible assets resulting from previous acquisitions, along with the costs of non-exclusive and perpetual worldwide software technology licenses and capitalized software development costs for both internal and external use. Finite-lived intangible assets are amortized on a straight-line basis over the estimated useful lives of the assets, which range fr om two definite-lived intangible assets, including in-process capitalized software development costs, are not amortized; however, they are tested for impairment annually, and between annual tests, if certain events occur indicating that the carrying amounts may be impaired. Software Development Costs for External Use Software development costs for external use are expensed as incurred until technological feasibility has been established, at which time those costs are capitalized as intangible assets until the software is available for general release to customers. Capitalized software development costs are amortized on a straight-line basis over the estimated economic life. The straight-line recognition method approximates the manner in which the expected benefit will be derived. Costs incurred to enhance existing software or after the software is available for general release to customers are expensed in the period they are incurred and included in research and development expense in the consolidated statements of operations. At each balance sheet date, the unamortized capitalized software development cost for external use is compared to its net realizable value by analyzing critical inputs such as expected future lifetime revenue. The amount by which unamortized software costs exceed the net realizable value, if any, is recognized as a charge to amortization expense in the period it is determined. Software Development Costs for Internal Use Costs incurred in the preliminary stages of development are expensed as incurred and included in research and development expense in the consolidated statements of operations. Once an application has reached the development stage, internal and external costs, if direct and incremental, are capitalized. Capitalization ceases upon completion of all substantial testing performed to ensure the product is ready for its intended use. The Company also capitalizes costs related to specific upgrades and enhancements of internal-use software when it is probable that the expenditures will result in additional functionality. Maintenance and training costs are expensed as incurred. Capitalized internal-use software costs are recorded as intangible assets and are amortized on a straight-line basis to general and administrative expense in the consolidated statement of operations over the estimated useful life of the software. The Company tests these assets for impairment whenever events or circumstances occur that could impact their recoverability. Valuation of Indefinite-Lived Intangible Assets The Company performs an annual impairment review of indefinite-lived assets during the fourth quarter of each year, and more frequently if the Company believes indicators of impairment exist. To review for impairment, the Company first assesses qualitative factors to determine whether events or circumstances lead to a determination that it is more likely than not that the fair value of the asset is less than its carrying amount. The Company’s qualitative assessment is based on various macroeconomic, industry-specific, and company specific factors. These factors include: (i) industry or economic trends; (ii) current, historical, or projected financial performance, and; (iii) the Company’s market capitalization. After assessing the totality of events and circumstances, if the Company determines that it is not more likely than not that the fair value of the asset is less than its carrying amount, then no further assessment is performed. If the Company determines that it is more likely than not that the fair value of the asset is less than its carrying amount, then the Company calculates the fair value of the asset and compares the fair value to the asset’s carrying value. An impairment charge is recognized if the asset’s estimated fair value is less than it’s carrying value. The Company did not record any impairment losses related to indefinite-lived intangible assets during the years ended December 31, 2023 and 2022. Goodwill Goodwill represents the excess purchase price over estimated fair value of net assets of businesses acquired in a business combination. Goodwill is tested for impairment during the fourth quarter of each year, and more frequently if the Company believes indicators of impairment exist. Valuation of Goodwill Goodwill is tested for impairment at the reporting unit level by first assessing qualitative factors to determine whether events or circumstances lead to a determination that it is more likely than not that the fair value of the Company’s reporting unit is less than its carrying amount. The Company’s qualitative assessment is based on various macroeconomic, industry-specific, and company specific factors. These factors include: (i) industry or economic trends; (ii) current, historical, or projected financial performance, and; (iii) the Company’s market capitalization. After assessing the totality of events and circumstances, if the Company determines that it is not more likely than not that the fair value of the Company’s reporting unit is less than its carrying amount, no further assessment is performed. If the Company determines that it is more likely than not that the fair value of the Company’s reporting unit is less than its carrying amount, the Company calculates the fair value of the reporting unit and compares the fair value to the reporting unit’s carrying amount. An impairment charge is recognized if the fair value of the business (reporting unit) is less than its carrying value. The Company has identified two reporting units for the purpose of goodwill impairment testing, Ctrack and Inseego North America (“INA”), and performed a qualitative test for goodwill impairment of the two reporting units during the fourth fiscal quarter. Based upon the results of qualitative testing, the Company believed that it was more-likely-than not that the fair value of these reporting units were greater than their respective carrying values. For the years ended December 31, 2023 and 2022, the Company recorded no impairment loss related to goodwill. Long-Lived Assets The Company periodically evaluates the carrying value of the unamortized balances of its long-lived assets, including property, plant and equipment and rental assets, to determine whether impairment of these assets has occurred or whether a revision to the related amortization periods should be made. If the carrying value of the long-lived asset group exceeds the estimated future undiscounted cash flows, an impairment loss is recorded based on the amount by which the asset group’s carrying amount exceeds its fair value. Fair value is determined based on an evaluation of the assets’ associated discounted future cash flows or appraised value . For the years ended December 31, 2023 and 2022, the Company had no impairment loss related to long-lived assets, except for the impairment of the capitalized software development costs for internal and external use, described further Note 3 – Goodwill and Other Intangible Assets . Property, Plant and Equipment Property, plant and equipment are initially stated at cost and depreciated using the straight-line method. Land is not depreciated. Buildings are depreciated over 50 years. Leasehold improvements are depreciated over the shorter of the related remaining lease period or useful life, not to exceed 5 years. Product tooling is depreciated over 13 months. Computer equipment, purchased software, vehicles, production equipment, and furniture and fixtures, are depreciated over lives ranging from 2 to 7 years. Amortization of equipment under finance leases is included in depreciation expense. Expenditures for repairs and maintenance are expensed as incurred. Expenditures for major renewals and betterment that extend the

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company’s only financial instrument measured at fair value on a recurring basis is its interest make-whole payment derivative liability on its 2025 Notes (see Note 5 – Debt ). The fair value of that liability was zero as of both December 31, 2023 and 2022. The fair value of the interest make-whole payment derivative liability was determined using a Monte Carlo model with the following key assumptions: December 31, 2023 December 31, 2022 Volatility 77 % 50 % Stock price $2.20 per share $8.40 per share Credit spread 92.20 % 56.52 % Term 1.34 years 2.34 years Dividend yield — % — % Risk-free rate 4.60 % 4.35 % The estimated fair value of the interest make-whole derivative liability at December 31, 2023 and December 31, 2022 was determined using assumptions which include an implied credit spread rate for notes with a similar term, the expected volatility and dividend yield of the Company’s common stock and the risk-free interest rate. During the years ended December 31, 2023 and 2022, there were no conversions of the 3.25% convertible senior notes due 2025 (the “2025 Notes”) into shares of the Company’s common stock. During the year ended December 31, 2023, there was no change in the fair value of the interest make-whole liability. For the year ended December 31, 2022, the Company recorded a $0.9 million gain as a result of the changes in fair value of the interest make-whole liability within other income (expense), net on the consolidated statement of operations. Other Financial Instruments The carrying values of the Company’s other financial assets and liabilities approximate their fair values because of their short-term nature, with the exception of the 2025 Notes. The 2025 Notes are carried at amortized cost, adjusted for changes in fair value of the embedded derivative.

Debt

Debt Disclosure [Abstract]
Debt	Debt Convertible Notes 2025 Notes In May 2020, the Company completed both a registered public offering, and a privately negotiated exchange agreement, that resulted in the issuance of the 2025 Notes. After taking into account exchanges and redemptions occurring in prior periods, the outstanding principal balance of the 2025 Notes was $161.9 million as of both December 31, 2023 and December 31, 2022 . The 2025 Notes were issued under an indenture, dated May 12, 2020 (the “Base Indenture”), between the Company and Wilmington Trust, National Association, as trustee (the “Trustee”), as supplemented by the first supplemental indenture, dated May 12, 2020 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and the Trustee. The 2025 Notes will mature on May 1, 2025, unless earlier repurchased, redeemed or converted. The 2025 Notes are senior unsecured obligations of the Company and bear interest at an annual rate of 3.25%, payable semi-annually in arrears on May 1 and November 1 of each year. Holders of the 2025 Notes may convert the 2025 Notes into shares of the Company’s common stock (together with cash in lieu of any fractional share), at their option, at any time until the close of business on the scheduled trading day immediately before the maturity date. Upon conversion of the 2025 Notes, the Company will deliver for each $1,000 principal amount of 2025 Notes converted a number of shares of the Company’s common stock (together with cash in lieu of any fractional share), equal to the conversion rate. The initial conversion rate for the 2025 Notes is 7.92896 shares of common stock per $1,000 principal amount of 2025 Notes, which represents an initial conversion price of approximately $126.12 per share, and is subject to adjustment upon the occurrence of certain events, including, but not limited to, certain stock dividends, splits and combinations, the issuance of certain rights, options or warrants to holders of the common stock, certain distributions of assets, debt securities, capital stock or other property to holders of the common stock, cash dividends on the common stock and certain Company tender or exchange offers. If a fundamental change (as defined in the Indenture) occurs at any time prior to the maturity date, then the noteholders may require the Company to repurchase their 2025 Notes at a cash repurchase price equal to the principal amount of the 2025 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. If a make-whole fundamental change (as defined in the Indenture) occurs, then the Company will in certain circumstances increase the conversion rate for a specified period of time. The 2025 Notes will be redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or after May 6, 2023 through the last scheduled trading day before the maturity date, at a cash redemption price equal to the principal amount of the 2025 Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, as long as the last reported sale price per share of the common stock exceeds 130% of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (ii) the trading day immediately before the date the Company sends such notice. The Indenture contains customary events of default. If an event of default (other than certain events of bankruptcy, insolvency or reorganization involving the Company) occurs and is continuing, the Trustee, by notice to the Company, or the holders of the 2025 Notes representing at least 25% in aggregate principal amount of the outstanding 2025 Notes, by notice to the Company and the Trustee, may declare 100% of the principal of, and all accrued and unpaid interest on, all of the then outstanding 2025 Notes to be due and payable immediately. Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving the Company, 100% of the principal of, and all accrued and unpaid interest on, all of the then outstanding 2025 Notes will automatically become immediately due and payable. Notwithstanding the foregoing, the Indenture provides that, to the extent the Company elects, the sole remedy for an event of default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture will, for the first 360 days after such event of default, consist exclusively of the right to receive additional interest on the 2025 Notes. Interest make-whole payment The 2025 Notes also include an interest make-whole payment feature whereby if the last reported sale price of the Company’s common stock for each of the five The Company has determined that this feature is an embedded derivative and has recognized the fair value of this derivative as a liability in the consolidated balance sheets, with subsequent changes to fair value to be recorded at each reporting period on the consolidated statement of operations in other income, net. See Note 4 – Fair Value Measurements , for more information on this derivative liability. As of December 31, 2023 and 2022, $161.9 million of principal of the 2025 Notes was outstanding, $80.4 million of which were held by related parties. Assuming no repurchases or conversions of the 2025 Notes prior to May 1, 2025, the entire principal balance of $161.9 million of the 2025 Notes is due on May 1, 2025. The 2025 Notes consist of the following (in thousands): December 31, 2023 2022 Principal $ 161,898 $ 161,898 Add: fair value of embedded derivative — — Less: unamortized debt discount (1,106) (1,933) Less: unamortized issuance costs (880) (1,538) Net carrying amount $ 159,912 $ 158,427 The effective interest rate of the liability component of the 2025 Notes was 4.17% for the twelve months ended December 31, 2023 and 2022. The following table sets forth total interest expense recognized related to the 2025 Notes (in thousands): Year Ended December 31, 2023 2022 Contractual interest expense $ 5,262 $ 5,262 Amortization of debt discount 828 828 Amortization of debt issuance costs 659 659 Total interest expense $ 6,749 $ 6,749 The contractual interest expense on the 2025 Notes recorded within interest expense, net on the consolidated statements of operations attributable to related parties was $2.6 million and $2.6 million in the years ended December 31, 2023 and 2022, respectively. As of both December 31, 2023 and 2022, accrued interest due to related parties of $0.4 million was included within accrued expenses and other current liabilities on the consolidated balance sheets. Asset-Backed Revolving Credit Facility On August 5, 2022, the Company entered into a Loan and Security Agreement (the “Credit Agreement”), by and among Siena Lending Group LLC, as lender (“Lender”), Inseego Wireless, Inc., a Delaware corporation (“Inseego Wireless”), a subsidiary of the Company, and Inseego North America LLC, an Oregon limited liability company, an indirect subsidiary of the Company, as borrowers (together with Inseego Wireless, the “Borrowers”), and the Company, as guarantor (together with the Borrowers, the “Loan Parties”) as subsequently amended (see Note 13 – Subsequent Events for further information on the most recent amendment) . The Credit Agreement establishes a secured asset-backed revolving credit facility which is comprised of a maximum $50 million revolving credit facility (“Credit Facility”), with a minimum borrowing amount for interest calculations of $4.5 million upon execution of the Credit Agreement. The Credit Facility matures on December 31, 2024. Availability under the Credit Facility is determined monthly by a borrowing base comprised of a percentage of eligible accounts receivable and eligible inventory of the Borrowers. Outstanding amounts exceeding the borrowing base must be repaid immediately. The Borrowers’ obligations under the Credit Agreement are guaranteed by the Company. The Loan Parties’ obligations under the Credit Agreement are secured by a continuing security interest in all property of each Loan Party, subject to certain Excluded Collateral (as defined in the Credit Agreement). Borrowings under the Credit Facility may take the form of base rate (“Base Rate”) loans or Secured Overnight Financing Rate (“SOFR”) loans. SOFR loans will bear interest at a rate per annum equal to Term SOFR (as defined in the Credit Agreement as the Term SOFR Reference Rate for a term of one month on the day) plus the Applicable Margin (as defined in the Credit Agreement), with a Term SOFR floor of 1%. Base Rate loans will bear interest at a rate per annum equal to the Applicable Margin plus the greatest of (a) the per annum rate of interest which is identified as the “Prime Rate” and normally published in the Money Rates section of The Wall Street Journal, (b) the sum of the Federal Funds Rate (as defined in the Credit Agreement) plus 0.5% and (c) 3.50% per annum. The Applicable Margin varies depending on the average outstanding amount for a preceding month. If the average outstanding amount for a preceding month is less than $15 million, the Applicable Margin will be 2.50% for Base Rate loans and 3.50% for SOFR loans. If the average outstanding amount for a preceding month is between $15 million and $25 million, the Applicable Margin will be 3.00% for Base Rate loans and 4.00% for SOFR loans. If the average outstanding amount for a preceding month is greater than $25 million, the Applicable Margin will be 4.5% for Base Rate loans and 5.50% for SOFR loans. The Company pays monthly fees of 0.4% per annum on the unused portion of the Credit Facility. The Credit Agreement contains a financial covenant whereby the Loan Parties shall not permit the consolidated Liquidity (as defined in the Amended Credit Agreement) to be less than $8 million at any time (the “Liquidity Covenant”). The Credit Agreement also contains certain customary covenants, which include, but are not limited to, restrictions on indebtedness, liens, fundamental changes, restricted payments, asset sales, and investments, and places limits on various other payments. The Company determined that the term “Eligible Accounts”, as defined in the Credit Agreement would have excluded certain balances used in the determination of eligible collateral upon which the Company’s borrowing base is calculated and that exclusion would have resulted in a violation of the Liquidity Covenant as of December 31, 2022. Accordingly, to clarify this matter and others, the Loan Parties agreed to amend the Credit Agreement (as amended, the “Amended Credit Agreement”) to modify and clarify the definitions of “Eligible Accounts”, “Permitted Indebtedness” and also “Eligible Inventory.” The Amended Credit Agreement was entered into on February 25, 2023 with an effective date of December 15, 2022. The Company was in compliance with the financial covenants of the Amended Credit Agreement as of December 31, 2023. On May 2, 2023, (1) two related parties (the “Participants”) collectively purchased a $4.0 million last-out subordinated participation interest in the Amended Credit Agreement (the “Participation Interest”) from the Lender, and (2) the Borrowers entered into an amendment to the Amended Credit Agreement which increased the borrowing base under the Credit Facility by $4.0 million, increased the minimum borrowing amount for interest calculations to $8.5 million, and modified certain covenants. In connection with the purchase of the Participation Interest, we agreed to pay the Participants an aggregate exit fee ranging from 7.5% to 12.5% of the amount of the Participation Interest, payable upon the earlier to occur of (a) the maturity date of the Credit Facility, (b) termination of the Lender’s commitment to make revolving loans prior to the scheduled maturity date of the Credit Facility, and (c) the early redemption of the Participation Interest, as applicable. Further, the purchase of the Participation Interest granted an option for the Participants to purchase the subject revolving loan or to redeem its Participation Interest under certain circumstances. The Participants are each affiliates of beneficial holders of greater than five percent of our outstanding common stock. Accretion of the exit fee attributable to related parties recorded within interest expense, net on the consolidated statements of operations was $0.2 million for the year ended December 31, 2023. Upon execution of the Credit Agreement on August 5, 2022, the Company paid $1.1 million of debt issuance costs, which are being amortized to interest expense throughout the term of the agreement. Amortization expense of $0.5 million and $0.2 million related to debt issuance cost was recognized for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023 and 2022, there were $0.5 million and $0.9 million of unamortized debt issuance costs on the Credit Facility included within prepaid expenses and other and other assets on the consolidated balance sheets, respectively. As of December 31, 2023, the Company had outstanding borrowings of $4.1 million and availability of $3.2 million. The Company’s policy is to classify outstanding borrowings as long-term so long as such borrowings are not expected to exceed the borrowing base over the 12 months subsequent to the balance sheet date, in which case, any excess borrowings would be classified as short-term. The effective interest rate of the average outstanding balance of the Credit Facility was 54.5%, which includes 14.4% related to amortization of original issuance costs, and 17.7%, which includes 8.5% related to amortization of original issuance costs, for the twelve months ended December 31, 2023 and 2022, respectively. The higher interest rates relate to the fact that there is a minimum borrowing amount for interest calculations under the Credit Facility. The following table sets forth total interest expense recognized related to the Credit Facility (in thousands): Year Ended December 31, 2023 2022 Contractual interest expense $ 861 $ 211 Amortization of debt issuance costs 466 194 Total interest expense $ 1,327 $ 405

The Company also recognizes federal, state and foreign deferred tax liabilities or assets based on the Company’s estimate of future tax effects attributable to temporary differences and carryforwards. The Company records a valuation allowance to reduce any deferred tax assets by the amount of any tax benefits that, based on available evidence and judgment, are not expected to be realized. The Company assesses whether a valuation allowance should be recorded against its deferred tax assets based on the consideration of all available evidence, using a “more likely than not” realization standard. The four sources of taxable income that must be considered in determining whether deferred tax assets will be realized are: (1) future reversals of existing taxable temporary differences (i.e., offset of gross deferred tax assets against gross deferred tax liabilities); (2) taxable income in prior carryback years, if carryback is permitted under the applicable tax law; (3) tax planning strategies; and (4) future taxable income exclusive of reversing temporary differences and carryforwards. During the years ended December 31, 2023 and 2022, the Company recognized valuation allowances of $10.1 million, and $13.6 million, respectively, related to its deferred tax assets created in those respective years for entities with historical losses and full valuation allowances. Based on the Company’s current position on valuation allowance, no net income tax benefits resulted in the Company’s consolidated statements of operations from the operating losses created during those years. Beginning January 1, 2022, we are required to capitalize certain research and development expenditures in accordance with Section 174 of the Internal Revenue Code, as amended by the Tax Cuts and Jobs Act of 2017, instead of expensing such expenditures, as previously allowed. Amortization of such capitalized expenditures are allowed over a 5-year period if incurred domestically or a 15-year period if incurred outside the United States. The (benefit) provision for income taxes reconciles to the amount computed by applying the statutory federal income tax rate of 21% in 2023 and 2022 to loss before income taxes as follows (in thousands): Year Ended December 31, 2023 2022 Federal tax benefit, at statutory rate $ (9,154) $ (14,371) State benefit, net of federal benefit 711 (370) Foreign tax rate difference 148 (259) Valuation allowance against future tax benefits 9,727 13,564 Research and development credits (760) (2,222) Share-based compensation 1,622 1,010 Non-deductible officers compensation — 108 True-up of prior year provisions (1,474) 2,123 Other 65 (48) (Benefit) Provision for income taxes $ 885 $ (465) At December 31, 2023, the Company had U.S. federal net operating loss carryforwards (“NOLs”) related to tax years 2021 and prior of approximately $405.1 million. Approximately $106.9 million of these NOLs have no expiration date. The remainder will begin to expire in 2024, unless previously utilized. Some of these NOLs may be limited by either past or future changes in control events. The Company has California NOLs at December 31, 2023 of approximately $64.2 million, which begin to expire in 2028, unless previously utilized, and foreign NOLs for its active foreign subsidiaries of approximately $25.5 million, which generally have no expiration date. At December 31, 2023, the Company had federal research and development tax credit carryforwards, net of unrecognized tax benefits, of approximately $10.9 million, which begin to expire in 2026, unless previously utilized, and California research and development tax credit carryforwards, net of unrecognized tax benefits, of approximately $10.9 million, which have no expiration date. Pursuant to Internal Revenue Code (“IRC”) Sections 382 and 383, annual use of the Company’s net operating loss and research and development credit carryforwards may be limited in the event a cumulative change in ownership of more than 50% occurs within a rolling three-year period. An analysis was performed for the period through December 31, 2023 and did not identify any events of cumulative change in ownership during the review period. The Company will continue monitoring any future changes in stock ownership. It is the Company’s intention to reinvest undistributed earnings of its foreign subsidiaries and thereby indefinitely postpone their remittance. Accordingly, no provision has been made for foreign withholding taxes on U.S. income taxes which may become payable if undistributed earnings of the foreign subsidiary were paid as dividends to the Company. On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which includes modifications to the limitation on business interest expense and net operating loss provisions, and provides a payment delay of employer payroll taxes during 2020 after the date of enactment. Payments of approximately $1.4 million of employer payroll taxes otherwise due in 2020, were delayed with 50% due and paid by December 31, 2021 and the remaining 50% in February 2023. The CARES Act did not have a material impact on the Company’s consolidated financial statements. The Company follows the accounting guidance related to financial statement recognition, measurement and disclosure of uncertain tax positions. The Company recognizes the impact of an uncertain income tax position on an income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. No income tax benefit was recognized during the years ended December 31, 2023 and 2022. At December 31, 2023 and 2022, the Company did not have interest expense related to uncertain tax positions or a liability for unrecognized tax benefits. The Company does not expect changes to its uncertain tax position in the next twelve months. A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows (in thousands): Balance at December 31, 2021 $ 41,629 Increases related to current and prior year tax positions 1,286 Balance at December 31, 2022 42,915 Increases related to current and prior year tax positions 506 Decreases from lapses of statute of limitations and prior year tax positions (30,782) Balance at December 31, 2023 $ 12,639 There are no tax benefits that, if recognized, would affect the effective tax rate that are included in the balances of unrecognized tax benefits at December 31, 2023. The Company and its subsidiaries file U.S., state and foreign income tax returns in jurisdictions with various statutes of limitations. The Company’s tax returns are subject to examination by federal, state and foreign taxing authorities. The Company’s federal and state tax returns are subject to examination for the years beginning in 2020 and 2019, respectively. Net operating loss carryforwards arising prior to these years are also open to examination, if and when utilized. The Company believes appropriate provisions for all outstanding issues have been made for all jurisdictions and all open years. However, because audit outcomes and the timing of audit settlements are subject to significant uncertainty, the Company’s current estimate of the total amounts of unrecognized tax benefits could increase or decrease for all open years. On August 16, 2022, Congress passed, and the President signed into law, the Inflation Reduction Act of 2022 (the “IRA”), which includes certain business tax provisions. The IRA provides for excise taxes on corporate stock buy-backs and a minimum tax on corporate financial statement income in excess of $1.0 billion. These new provisions became effective January 1, 2023. The Company does not expect the IRA to have a material impact on the Company’s effective tax rate or income tax expense for the year ending December 31, 2023.

Preferred Stock and Common Stock	Preferred Stock and Common Stock Preferred Stock The Company has a total of 2,000,000 shares of preferred stock authorized for issuance at a par value of $0.001 per share, 150,000 of which have been designated Series D Preferred Stock and 39,500 of which have been designated Series E Preferred Stock. As of December 31, 2023, the Company had 25,000 shares of Series E preferred stock issued and outstanding. Each share of Series E Preferred Stock entitles the holder thereof to receive, when and if declared by the Company out of assets legally available therefor, cumulative cash dividends at an annual rate of 9.00% payable quarterly in arrears on January 1 April 1, July 1 and October 1 of each year, beginning on October 1, 2019. If dividends are not declared and paid in any quarter, or if such dividends are declared but holders of the Series E Preferred Stock elect not to receive them in cash, the quarterly dividend will be deemed to accrue and will be added to the Series E Base Amount (as defined below). The Series E Preferred Stock has no voting rights unless otherwise required by law. The Series E Preferred Stock is perpetual and has no maturity date. However, the Company may, at its option, redeem shares of the Series E Preferred Stock, in whole or in part, on or after July 1, 2022, at a price equal to 110% of the Series E Base Amount plus (without duplication) any accrued and unpaid dividends. The “Series E Base Amount” means $1,000 per share, plus any accrued but unpaid dividends, whether or not declared by the Company’s board of directors, subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Series E Preferred Stock. In the event of a liquidation, dissolution or winding up of the Company, the holders of the Series E Preferred Stock will be entitled to receive, after satisfaction of liabilities to creditors and subject to the rights of holders of any senior securities, but before any distribution of assets is made to holders of common stock or any other junior securities, the Series E Base Amount plus (without duplication) any accrued and unpaid dividends. Dividends declared, but not paid, related to the Series E Preferred Stock resulted in $10.1 million and $7.1 million of dividends accrued, approximating $404.93 and $285.29 per preferred share, as of December 31, 2023 and 2022, respectively. Common Stock As of December 31, 2023, the Company had 150,000,000 shares of $0.001 par value common stock authorized for issuance and 11,878,557 shares issued and outstanding. In January 2021, the Company entered into an Equity Distribution Agreement with Canaccord Genuity LLC (the “Agent”), pursuant to which the Company may offer and sell, from time to time, through or to the Agent, up to $40.0 million of shares of its common stock (the “ATM Offering”). There were no sales under the ATM during the year ended December 31, 2022. During the year ended December 31, 2023 the Company sold 803,596 shares of common stock, at an average price of $7.54 per share, for net proceeds of $5.9 million, after deducting underwriter fees and discounts. Effective as of November 2, 2023, the Equity Distribution Agreement was terminated by the Company, and there will be no further sales under the ATM Offering.

The Compensation Committee of the Board of Directors administers the plans. Under the 2018 Plan, shares of common stock may be issued upon the exercise of stock options, in the form of restricted stock, or in settlement of RSUs or other awards, including awards with alternative vesting schedules such as performance-based criteria. The 2018 Plan authorizes 3,275,309 shares, of which 910,076 remain available for future grants. During the year ended December 31, 2023 and 2022, the Board of Directors of the Company approved and the Company granted RSUs to eligible employees under the 2018 Plan, previously named the Amended and Restated 2009 Omnibus Incentive Compensation Plan (the “2018 Plan”), as annual bonus payments. During the years ended December 31, 2023 and 2022, the total charges related to bonus payments were $1.2 million and $8.8 million, respectively.

Restricted Stock Units Pursuant to the 2018 Plan and the 2015 Plan, the Company may issue RSUs that, upon satisfaction of vesting conditions, allow recipients to receive common stock. Issuances of such awards reduce common stock available under the 2018 Plan and 2015 Plan for stock incentive awards.

Earnings Per Share [Abstract]
Loss per Share	Loss per Share Basic EPS excludes dilution and is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock using the treasury stock method. Potentially dilutive securities (consisting primarily of the convertible notes calculated using the if-converted and treasury stock method and warrants, stock options and RSUs calculated using the treasury stock method) are excluded from the diluted EPS computation in loss periods and when the applicable exercise price is greater than the market price on the period end date as their effect would be anti-dilutive. The calculation of basic and diluted earnings per share was as follows (in thousands, except share and per share data): Year Ended December 31, 2023 2022 Net loss attributable to common stockholders $ (49,176) $ (70,705) Weighted-average common shares outstanding * 11,372,069 10,726,933 Basic and diluted net loss per share $ (4.32) $ (6.59) (*) Adjusted retroactively for reverse stock split that occurred on January 24, 2024, see Note 1 The following is a summary of outstanding potential shares of common stock that have been excluded from the computation of diluted net loss per share attributable to common stockholders because their inclusion would have been anti-dilutive: Year Ended December 31, (in thousands) 2023 2022 Convertible notes 1,291 1,409 Non-qualified stock options 546 813 Restricted stock units 203 118 Employee Stock Purchase Plan 25 43 Total 2,065 2,383

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Noncancellable Purchase Obligations The Company typically enters into commitments with its contract manufacturers that require future purchases of goods or services in the upcoming three to four quarters following the balance sheet date. Such commitments are noncancellable (“noncancellable purchase obligations). As of December 31, 2023, future payments under these noncancellable purchase obligations were approximately $33.9 million. Legal The Company is, from time to time, party to various legal proceedings arising in the ordinary course of business. The Company is regularly required to directly or indirectly participate in other U.S. patent infringement actions pursuant to its contractual indemnification obligations to certain customers. Based on an evaluation of these matters the Company currently believes that liabilities arising from, or sums paid in settlement of these existing matters, if any, would not have a material adverse effect on its consolidated results of operations or financial condition. Indemnification In the normal course of business, the Company periodically enters into agreements that require the Company to indemnify and defend its customers for, among other things, claims alleging that the Company’s products infringe upon third-party patents or other intellectual property rights. The Company’s maximum exposure under these indemnification provisions cannot be estimated but the Company does not believe that there are any matters individually or collectively that would have a material adverse effect on its consolidated results of operations or financial condition.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Basis of presentation	Basis of presentation The consolidated financial statements of Inseego Corp. present information in accordance with generally accepted accounting principles in the U.S. (“GAAP”), have been prepared pursuant to the rules and regulations of the SEC and, in the opinion of management, present fairly the consolidated financial position, results of operations and cash flows of the Company and its wholly-owned subsidiaries for the periods presented.
Reclassifications	Reclassifications Certain amounts recorded in the prior period consolidated financial statements have been reclassified to conform to the current period financial statement presentation. These reclassifications had no effect on previously reported operating results.
Segment Information	Segment Information
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent liabilities. Actual results could differ materially from these estimates. Estimates are assessed each period and updated to reflect current information. Significant estimates include revenue recognition, capitalized software costs, allowance for credit losses, provision for excess and obsolete inventory, accrued liabilities related to our contract manufacturers, valuation of tangible and intangible long-lived assets, valuation of goodwill, valuation of derivatives, accruals relating to litigation, income taxes and share-based compensation expense.
Risks and Uncertainties	Risks and Uncertainties We may be affected by various macroeconomic factors and the current and future conditions in the global financial markets. The global credit and financial markets have recently experienced volatility and disruptions, including diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, rising interest rates, inflation, increases in unemployment rates and uncertainty about economic stability. The inflationary pressures impacting the global supply chain could potentially increase the cost of revenues in the current and future years. The ongoing inflation challenges could adversely impact future revenues, gross margins and financial results. Furthermore, a global semiconductor supply shortage continues to have wide-ranging impacts across the technology industry. While the shortage has not materially impacted the Company’s operations and financial results, it may negatively impact the Company’s customers and the supply of materials needed for testing and production timeline. The Company’s suppliers, contract manufacturers, and customers are all taking actions to reduce the impact of the semiconductor shortage; however, if the shortage persists, the impact on operations and financial results could be material.

Revenue Recognition	Revenue Recognition The Company’s products and services primarily include intelligent mobile hotspots, wireless routers for IoT applications, USB modems, integrated telematics and mobile tracking hardware devices, which are supported by applications software and cloud services designed to enable customers to easily analyze data insights and configure and manage their hardware. The Company classifies its revenues from the sale of its products and services into two categories, Product Revenue, which consists of our Mobile Solutions and Fixed Wireless Access Solutions, and Services and Other. See geographic disaggregation information in Note 12 – Geographic Information and Concentrations of Risk . Mobile solutions: Our Mobile wireless product portfolio consists of intelligent mobile broadband solutions, HD quality VoLTE products, 4G mobile solutions and an advanced 5G portfolio of mobile products. Our mobile broadband solutions, sold under the MiFi brand, are actively used by millions of end users annually to provide secure and convenient high-speed access to corporate, public and personal information through the Internet and enterprise networks. Our mobile portfolio includes cloud offerings with Inseego Connect for device management, and 5G SD EDGE for secure networking enabling corporate managed mobile remote workforce. Fixed wireless access solutions: O ur Fixed Wireless Solutions product portfolio consists of indoor, outdoor and industrial wireless broadband solutions. Our Fixed Wireless solutions, sold under the Wavemaker and Skyus brands, are sold by wireless operators such as T-Mobile, U.S. Cellular and Verizon Wireless along with distribution and channel partners. Services and other: Services and other primarily consists of various subscription offerings within the Company’s telematics platforms, which provide fleet vehicle, aviation ground vehicle and asset tracking and performance information, and other telematics applications; services performed under our Inseego Subscribe SaaS application, which provides managed the selection, deployment, and spend of customers’ wireless assets; and non-recurring engineering services provided to our customers. Revenue Recognition Criteria The Company follows Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) (as amended, “ASC 606”), which provides guidance on recognizing revenue, including a five-step model to determine when revenue recognition is appropriate. The standard requires that an entity recognize revenue to depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company recognizes revenue upon transfer of control of products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company determines revenue recognition according to the following five steps: (i) identification of the contract, or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when, or as, performance obligations are satisfied. Substantially all of our product revenues are recognized at a point in time, while substantially all of our service and other revenues are recognized over time. Customer Contracts The Company routinely enters into a variety of agreements with customers, including quality agreements, pricing agreements and master supply agreements which outline the general commercial terms and conditions under which the Company does business with a specific customer, including shipping terms and pricing for the products and services that the Company offers. The Company also sells to some customers solely based on purchase orders. The Company has concluded, for the vast majority of its revenues, that its contracts with customers are either a purchase order or the combination of a purchase order with a master supply agreement. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Performance Obligations The Company’s performance obligations are established when a customer submits a purchase order notification (in writing, electronically or verbally) for goods and services, and the Company accepts the order. The Company identifies performance obligations as the delivery of the requested product or service in appropriate quantities and to the location specified in the customer’s contract and/or purchase order. The Company generally recognizes revenue upon the satisfaction of these criteria when control of the product or service has been transferred to the customer at which time the Company has an unconditional right to receive payment. The Company’s prices are fixed and have no history of being affected by contingent events that could impact the transaction price. The Company does not offer price concessions and does not accept payment that is less than the price stated upon acceptance of a customer purchase order. The Company enters into contracts that may include various combinations of products and services which are generally capable of being distinct and accounted for as separate performance obligations. Hardware. Hardware revenue from the sale of the Company’s devices is recognized when the Company transfers control to the customer, typically at the time when the product is delivered, shipped or installed, at which time, title passes to the customer and there are no further performance obligations with regards to the hardware device. The Company also considered the performance obligations in its customer master supply agreements and determined that, for the majority of its revenue, the Company generally satisfies performance obligations at a point in time upon delivery of the product to the customer. Maintenance and support services revenue. Periodically, the Company sells separately-priced warranty contracts that extend beyond the Company’s base warranty period. The separately priced service contracts range from 12 to 36 months. The Company typically receives payment at the inception of the contract and recognizes revenue as earned on a straight-line basis over the term of the contract. The Company’s estimated allowances for product warranties can vary from actual results and the Company may have to record additional charges to cost of revenue. Within cost of revenue, the Company records an estimate to reflect its standard warranty obligation to end users to provide for replacement of a defective product. The standard obligation period for most regions is 12 months. Factors that affect the warranty obligation include product failure rates, material usage, and service delivery costs incurred in correcting product failures. SaaS and other services. SaaS subscription revenue is recognized over time on a ratable basis over the contract term beginning on the date that its service is made available to the customer. Subscription periods range from monthly to multi-year, with the majority of contracts being one Our telematics services include devices which collect and transmit information from vehicles or other assets. The Company’s customers have an option to purchase the monitoring device or lease it over the term of the contract. If the customer purchases the hardware device, the Company recognizes the revenue at a point in time as discussed above. Because the Company’s rental asset contracts qualify as operating leases under Accounting Standards Codification (“ASC”) 842, Leases , and the contracts also include services to operate and maintain the underlying asset, the Company has elected to combine the lease and non-lease components because the service is the predominant element in the eyes of the customer and the pattern of service delivery is the same for both elements. The Company recognizes revenue ratably over time throughout the term of the contract. Professional services revenue. From time to time, the Company enters into special engineering design service agreements. Revenues from engineering design services are designed to meet specifications of a particular product, and therefore do not create an asset with an alternative use. The Company recognizes revenue based on the achievement of certain applicable milestones and the amount of payment the Company believes it is entitled to at the time. Multiple performance obligations. The Company’s contracts with customers may include commitments to transfer multiple products and services to a customer. When hardware, software and services are sold in various combinations, judgment is required to determine whether each performance obligation is considered distinct and accounted for separately, or not distinct and accounted for together with other performance obligations. The Company considered the performance obligations in its customer master supply agreements and determined that, for the majority of its revenue, the Company generally satisfies performance obligations at a point in time upon delivery of the product to the customer. In instances where the software elements included within hardware for various products are considered to be functioning together with non-software elements to provide the tangible product’s essential functionality, these arrangements are accounted for as a single distinct performance obligation. Judgment is required to determine the stand-alone selling price (“SSP”) for each distinct performance obligation. When available, the Company uses observable inputs to determine SSP. In instances where SSP is not directly observable, such as when the Company does not sell the product or service separately, it determines the SSP based on a cost-plus model as market and other observable inputs are seldom present based on the proprietary nature of the Company’s products. Contract Assets The Company capitalizes sales commissions earned by its sales force as contract acquisition costs if such costs are significant and both incremental and recoverable. Any capitalized sales commissions are either deferred and amortized over a period of benefit exceeding one year or are expensed as incurred if the period of benefit is one year or less. There were no contract assets related to customer acquisition costs as of December 31, 2023 or 2022 since the Company’s customer contracts are predominantly hardware sales that are immediately recognized as revenue upon either shipment or delivery, and therefore the related contract acquisition costs are also immediately recognized. Sales commissions are included in sales and marketing expense as incurred. Sales commissions associated with SaaS offerings are not material. Contract Liabilities Timing of revenue recognition may differ from the timing of invoicing to customers. If customers are invoiced for subscription services in advance of the service period, then deferred revenue is recorded. Contract liabilities are also recorded when the Company collects payments in advance of performing the services. As of December 31, 2023 and 2022, the Company had contract liabilities comprised of $5.6 million and $5.1 million of short-term deferred revenue included within accrued expenses and other current liabilities and $1.7 million and $0.6 million of long-term deferred revenue included within other long-term liabilities on the consolidated balance sheets, respectively. Cost of Revenues Cost of revenues includes the costs associated with the manufacturing of our portfolio of hardware devices, as well as direct personnel costs for employees and contractors, depreciation and amortization, and other period adjustments related to costs of inventories sold or for sale or use in manufacturing. Shipping and Handling Charges Fees charged to customers for shipping and handling of products are included in product revenues, and costs for shipping and handling of products are included as a component of sales and marketing expense. Shipping and handling costs were approximately $1.0 million and $2.3 million for the years ended December 31, 2023 and December 31, 2022, respectively. Taxes Collected from Customers
Accounts Receivable	Accounts receivable are customer obligations generally due under normal trade terms for the industry. Credit terms are granted and periodically revised based on evaluations of the customer’s financial condition. The Company performs ongoing credit evaluations of its customers. The Company’s payment terms are generally net 30 days from invoice date and could go up to 90 days for large carrier customers.
Allowance for Expected Credit Losses	The Company recognizes an allowance for credit losses at the time a receivable is recorded based on its estimate of expected credit losses and adjusts this estimate over the life of the receivable as needed. The Company evaluates the aggregation and risk characteristics of a receivable pool and develops loss rates that reflect historical collections, current forecasts of future economic conditions over the time horizon the Company is exposed to credit risk, and payment terms or conditions that may materially affect future forecasts. As needed, amounts are written-off when determined to be uncollectible.
Inventories and Provision for Excess and Obsolete Inventory	Inventories and Provision for Excess and Obsolete Inventory Inventories are stated at the lower of cost (first-in, first-out method) or net realizable value. Inbound shipping and handling costs are classified as a component of cost of revenues in the consolidated statements of operations. The Company reviews the components of its inventory and its inventory purchase commitments on a regular basis for excess and obsolete inventory based on estimated future usage and sales. Write-downs in inventory value or losses on inventory purchase commitments depend on various items, including factors related to customer demand, economic and competitive conditions, technological advances or new product introductions by the Company or its customers that vary from its current expectations. Whenever inventory is written down, a new cost basis is established and the inventory is not subsequently written up if market conditions improve.
Intangible Assets	Intangible Assets other than Goodwill Intangible assets include purchased finite-lived and indefinite-lived intangible assets resulting from previous acquisitions, along with the costs of non-exclusive and perpetual worldwide software technology licenses and capitalized software development costs for both internal and external use. Finite-lived intangible assets are amortized on a straight-line basis over the estimated useful lives of the assets, which range fr om two definite-lived intangible assets, including in-process capitalized software development costs, are not amortized; however, they are tested for impairment annually, and between annual tests, if certain events occur indicating that the carrying amounts may be impaired. Software Development Costs for External Use Software development costs for external use are expensed as incurred until technological feasibility has been established, at which time those costs are capitalized as intangible assets until the software is available for general release to customers. Capitalized software development costs are amortized on a straight-line basis over the estimated economic life. The straight-line recognition method approximates the manner in which the expected benefit will be derived. Costs incurred to enhance existing software or after the software is available for general release to customers are expensed in the period they are incurred and included in research and development expense in the consolidated statements of operations. At each balance sheet date, the unamortized capitalized software development cost for external use is compared to its net realizable value by analyzing critical inputs such as expected future lifetime revenue. The amount by which unamortized software costs exceed the net realizable value, if any, is recognized as a charge to amortization expense in the period it is determined. Software Development Costs for Internal Use Costs incurred in the preliminary stages of development are expensed as incurred and included in research and development expense in the consolidated statements of operations. Once an application has reached the development stage, internal and external costs, if direct and incremental, are capitalized. Capitalization ceases upon completion of all substantial testing performed to ensure the product is ready for its intended use. The Company also capitalizes costs related to specific upgrades and enhancements of internal-use software when it is probable that the expenditures will result in additional functionality. Maintenance and training costs are expensed as incurred. Capitalized internal-use software costs are recorded as intangible assets and are amortized on a straight-line basis to general and administrative expense in the consolidated statement of operations over the estimated useful life of the software. The Company tests these assets for impairment whenever events or circumstances occur that could impact their recoverability. Valuation of Indefinite-Lived Intangible Assets
Goodwill	Goodwill Goodwill represents the excess purchase price over estimated fair value of net assets of businesses acquired in a business combination. Goodwill is tested for impairment during the fourth quarter of each year, and more frequently if the Company believes indicators of impairment exist. Valuation of Goodwill
Long-Lived Assets	Long-Lived Assets The Company periodically evaluates the carrying value of the unamortized balances of its long-lived assets, including property, plant and equipment and rental assets, to determine whether impairment of these assets has occurred or whether a revision to the related amortization periods should be made. If the carrying value of the long-lived asset group exceeds the estimated future undiscounted cash flows, an impairment loss is recorded based on the amount by which the asset group’s carrying amount exceeds its fair value. Fair value is determined based on an evaluation of the assets’ associated discounted future cash flows or appraised value . For the years ended December 31, 2023 and 2022, the Company had no impairment loss related to long-lived assets, except for the impairment of the capitalized software development costs for internal and external use, described further Note 3 – Goodwill and Other Intangible Assets . Property, Plant and Equipment Property, plant and equipment are initially stated at cost and depreciated using the straight-line method. Land is not depreciated. Buildings are depreciated over 50 years. Leasehold improvements are depreciated over the shorter of the related remaining lease period or useful life, not to exceed 5 years. Product tooling is depreciated over 13 months. Computer equipment, purchased software, vehicles, production equipment, and furniture and fixtures, are depreciated over lives ranging from 2 to 7 years. Amortization of equipment under finance leases is included in depreciation expense. Expenditures for repairs and maintenance are expensed as incurred. Expenditures for major renewals and betterment that extend the useful lives of existing property, plant and equipment are capitalized and depreciated. Upon retirement or disposition of property, plant and equipment, any resulting gain or loss is recognized in other income (expense), net, in the consolidated statements of operations. Rental Assets three
Convertible Debt Instruments	Convertible Debt Instruments The Company evaluates embedded features within convertible debt that will be settled in shares upon conversion under ASC 815, Derivatives and Hedging (“ASC 815”) to determine whether the embedded feature(s) should be bifurcated from the host instrument and accounted for as a derivative at fair value with changes in fair value recorded in earnings. If an embedded derivative is bifurcated from share-settled convertible debt, then the Company records the debt component at cost less a debt discount equal to the bifurcated derivative’s fair value. The Company amortizes the debt discount over the life of the debt instrument as additional non-cash interest expense utilizing the effective interest method. The convertible debt and the derivative liability are presented in total on the consolidated balance sheet. The derivative liability is remeasured at each reporting period with changes in fair value recorded in the consolidated statements of operations within other income (expense), net.
Derivative Financial Instruments	Derivative Financial Instruments The Company evaluates stock warrants, debt instruments and other contracts to determine if those contracts or embedded components of those contracts qualify as derivative financial instruments to be separately accounted for under the relevant sections of ASC 815. The result of this accounting treatment could be that the fair value of a financial instrument is classified as a derivative financial instrument and is marked-to-market at each balance sheet date and recorded as an asset or liability. In the event that the fair value is recorded as an asset or liability, the change in fair value is recorded in the consolidated statements of operations as other income or other expense. Upon conversion, exercise or expiration of a derivative financial instrument, the instrument is marked to fair value.
Research and Development	Research and Development Research and development expense consists primarily of personnel costs for our engineers engaged in the design and development of our products, software and technologies, project material costs, services, depreciation and amortization. Such costs are charged to research and development expense as they are incurred, to the extent not capitalized as software development costs for external or internal use.
Lease Accounting	Lease Accounting Lessee Arrangements The Company determines if an arrangement contains a lease at inception. The Company primarily leases office space, automobiles and equipment. Certain of the Company’s leases contain provisions that provide for one or more options to renew at the Company’s sole discretion. Certain real estate leases also include executory costs such as common area maintenance. The Company accounts for lease and non-lease components, including common area maintenance, as a single lease component as a practical expedient election. None of the Company’s operating lease agreements contain any material residual value guarantees or material restrictive covenants. Right-of-use (“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. ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The lease term includes the base non-cancelable term, and any renewal options that are reasonably certain to be exercised at the commencement date. The Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. ROU assets also include any lease prepayments made and exclude lease incentives. Rental expense related to operating leases is recognized on a straight-line basis over the lease term. The Company has elected the practical expedient to exclude any short-term lease, defined as a lease with an original term of 12 months or less, from the provisions of ASC 842, Leases . Variable lease payments that do not depend on an index or rate are excluded from the measurement of ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. The Company has elected not to present short-term leases on the consolidated balance sheet as these leases have a lease term of 12 months or less at lease inception and do not contain purchase options or renewal terms that the Company is reasonably certain to exercise. Lessor Arrangements The Company serves as lessor for certain monitoring device leases and classifies such arrangements as operating leases. Accordingly, the Company carries rental devices at historical cost less accumulated depreciation and impairment, if any. The Company combines the lease and the non-lease components under these arrangements because the service is the predominant element from the customer’s perspective and the pattern of service delivery is the same for both elements. The Company accounts for the combined component as a single performance obligation under ASC 606.
Foreign Currency Transactions and Translation	Foreign Currency Transactions Foreign currency transactions are transactions denominated in a currency other than a subsidiary’s functional currency. A change in the exchange rate between a subsidiary’s functional currency and the currency in which a transaction is denominated increases or decreases the expected amount of functional currency cash flows upon settlement of the transaction. Such increase or decrease is reported by the Company as a foreign currency transaction gain or loss within Other income (expense), net, in the consolidated statements of operations. We recognize foreign currency transaction gains and losses primarily on intercompany transactions between certain subsidiaries in foreign countries. Based upon historical experience, the Company anticipates repayment of these transactions in the foreseeable future and recognizes realized and unrealized gains and losses on these transactions in the period in which they occur. Foreign Currency Translation Assets and liabilities of the Company’s international subsidiaries in which the local currency is the functional currency are translated into U.S. Dollars at period-end exchange rates. Income and expenses are translated into U.S. Dollars at the average exchange rates during the period. The resulting translation adjustments are included in the Company’s consolidated balance sheets as a component of accumulated other comprehensive loss.
Income Taxes	Income Taxes The Company recognizes federal, state and foreign current tax liabilities or assets based on its estimate of taxes payable to or refundable by tax authorities in the current fiscal year. The Company also recognizes federal, state and foreign deferred tax liabilities or assets based on the Company’s estimate of future tax effects attributable to temporary differences and carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more likely than not that some portion of the deferred tax asset will not be realized. The Company evaluates deferred income taxes on a quarterly basis to determine if valuation allowances are required by considering available evidence. If the Company is unable to generate sufficient future taxable income in certain tax jurisdictions, or if there is a material change in the actual effective tax rates or time period within which the underlying temporary differences become taxable or deductible, the Company could be required to increase its valuation allowance against its deferred tax assets which could result in an increase in the Company’s effective tax rate and an adverse impact on operating results. The Company will continue to evaluate the necessity of the valuation allowance based on the remaining deferred tax assets. The Company recognizes the impact of an uncertain income tax position on an income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Uncertain tax positions are recognized in the first subsequent financial reporting period in which that threshold is met or from changes in circumstances such as the expiration of applicable statutes of limitations. The Company’s policy is to include interest and penalties related to such positions as a component of income tax expense.
Litigation	Litigation The Company is, from time to time, party to various legal proceedings arising in the ordinary course of business. The Company records a loss when information indicates that a loss is both probable and reasonably estimable. Where a liability is probable and there is a range of estimated loss with no best estimate in the range, the Company records the minimum estimated liability related to the claim. As additional information becomes available, the Company revises its estimates, if necessary. The Company expenses litigation costs as incurred.
Share-Based Compensation	Share-Based Compensation The Company has granted stock options and restricted stock units (“RSUs”) to employees, non-employee consultants and non-employee members of our Board of Directors. The Company also has an employee stock purchase plan (“ESPP”) for eligible employees. The Company measures the compensation cost associated with all share-based payments based on grant date fair values. The fair value of each stock option and stock purchase right is estimated on the date of grant using an option pricing model that meets certain requirements. The Company generally uses the Black-Scholes option pricing model to estimate the fair value of its stock options and stock purchase rights. The determination of the fair value of share-based payment awards utilizing the Black-Scholes model is affected by the Company’s stock price and a number of assumptions, including expected volatility, expected term, risk-free interest rate and expected dividends. For grants of stock options, the Company uses a blend of historical and implied volatility for traded options on its stock in order to estimate the expected volatility assumption required in the Black-Scholes model. The Company’s use of a blended volatility estimate in computing the expected volatility assumption for stock options is based on its belief that while the implied volatility is representative of expected future volatility, the historical volatility over the expected term of the award is also an indicator of expected future volatility. Due to the short duration of stock purchase rights under the Company’s ESPP, the Company utilizes a blended volatility estimate that consists of implied volatility and historical volatility in order to estimate the expected volatility assumption of the Black-Scholes model. The expected term of stock options granted is estimated using historical experience. The risk-free interest rate assumption is based on observed interest rates appropriate for the expected terms of the Company’s stock options and stock purchase rights. The dividend yield assumption is based on the Company’s history and expectation of no dividend payouts. The Company estimates forfeitures at the time of grant and revises these estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company estimates its forfeiture rate assumption for all types of share-based compensation awards based on historical forfeiture rates related to each category of award. Compensation cost associated with grants of restricted stock units are measured at fair value, which has historically been the closing price of the Company’s common stock on the date of grant. The Company recognizes share-based compensation expense over the requisite service period of each individual award, which generally equals the vesting period, using the straight-line method for awards that contain only service conditions. For awards that contain performance conditions, the Company recognizes the share-based compensation expense on a straight-line basis for each vesting tranche, when achievement of that tranche is considered probable.

Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). A fair value measurement reflects the assumptions market participants would use in pricing an asset or liability based on the best available information. These assumptions include the risk inherent in a particular valuation technique (such as a pricing model) and the risks inherent in the inputs to the model. The Company classifies inputs to measure fair value using a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The categorization of financial instruments within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is prioritized into three levels and is defined as follows: Level 1: Pricing inputs are based on quoted market prices for identical assets or liabilities in active markets (e.g., NYSE or NASDAQ). Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Pricing inputs include benchmark yields, trade data, reported trades and broker dealer quotes, two-sided markets and industry and economic events, yield to maturity, Municipal Securities Rule Making Board reported trades and vendor trading platform data. Level 2 includes those financial instruments that are valued using various pricing services and broker pricing information including Electronic Communication Networks and broker feeds. Level 3 : Pricing inputs include significant inputs that are generally less observable from objective sources, including the Company’s own assumptions.
Comprehensive Loss	Comprehensive Loss Comprehensive loss consists of two components: net loss and other comprehensive loss. Other comprehensive loss refers to losses that are recorded as an element of stockholders’ deficit and are excluded from net loss. The Company’s other comprehensive loss is currently composed of foreign currency translation adjustments.
Recently Adopted Accounting Pronouncements and Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40)- Accounting For Convertible Instruments and Contracts in an Entity's Own Equity . The ASU simplifies accounting for convertible instruments by removing major separation models required under current GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for it. The ASU also simplifies the diluted net income per share calculation in certain areas. The guidance is effective for annual and interim periods beginning after December 15, 2021. The Company adopted the ASU in the first quarter of 2022 and there was no impact to the consolidated financial statements. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). The ASU addresses issuer’s accounting for certain modifications or exchanges of freestanding equity-classified written call options. The ASU is effective for annual and interim periods beginning after December 15, 2021. The Company adopted the ASU in the first quarter of 2022 and there was no impact to the consolidated financial statements. In September 2022, the FASB issued ASU No. 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50). The ASU requires disclosure of the key terms of outstanding supplier finance programs and a rollforward of the related obligations. The ASU does not affect the recognition, measurement or financial statement presentation of supplier finance program obligations. The ASU is effective for annual and interim periods beginning after December 15, 2022, except for the rollforward requirement, which is effective for annual periods beginning after December 15, 2023. The Company adopted the ASU in the first quarter of 2023 and there was no impact to the consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative . The FASB issued the standard to introduce changes to US GAAP that originate in either SEC Regulation S-X or S-K, which are rules about the form and content of financial reports. The provisions of the standard are contingent when the SEC removes the related disclosure provisions from Regulation S-X and S-K. The company does not expect the provisions of the standard to have a material impact on the Company's financial statements and related disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires that an entity report segment information in accordance with Topic 280, Segment Reporting. The amendment in the ASU is intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of the new standard on its consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures
