Accounting Policies [Abstract] |
Description of Business | Description of Business Airgain, Inc. was incorporated in the State of California on March 20, 1995; and reincorporated in the State of Delaware on August 17, 2016. Airgain, Inc. together with its subsidiaries are herein referred to as the “Company,” “we,” or “our.” The Company is a leading provider of connectivity solutions including embedded components, external antennas, and integrated systems that enable wireless networking in the consumer, enterprise, and automotive markets. The Company’s headquarters is in San Diego, California.
Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding financial reporting. The consolidated financial statements include the accounts of the Company and our wholly owned subsidiary. All intercompany transactions and investments have been eliminated in consolidation.
Segment Information | Segment Information The Company’s operations are located primarily in the United States and most of its assets are located in San Diego, California and Plymouth, Minnesota. The Company operates in one segment related to providing connectivity solutions – embedded components, external antennas, and integrated systems. The Company’s chief operating decision-maker is our chief executive officer, who reviews operating results on an aggregate consolidated basis for purposes of regularly making operating decisions, allocation of resources and assessing performance as a single operating segment.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash Equivalents | Cash Equivalents Cash equivalents are comprised of short-term, highly liquid investments with maturities of 90 days or less at the date of purchase. The cash balances may, at times, exceed federally insured limits. Accounts are guaranteed by the Federal Deposit Insurance Corporation (FDIC) up to $250,000.
Trade Accounts Receivable | Trade Accounts Receivable We perform ongoing credit evaluations of our customers and assess each customer’s credit worthiness. The policy for determining when receivables are past due or delinquent is based on the contractual terms agreed upon. We monitor collections and payments from our customers and analyze for an allowance for credit losses. The allowance for credit losses is based upon applying an expected credit loss rate to receivables based on the historical loss rate and is adjusted for current conditions, including any specific customer collection issues identified, and economic conditions forecast. Delinquent account balances are written off after management has determined that the likelihood of collection is remote. An allowance for doubtful accounts is established when, in the opinion of management, collection of the account is doubtful.
Inventory | Inventory As of April 2022, all of the Company’s products are manufactured by third parties that retain ownership of the inventory until title is transferred to the customer at the shipping point. In some situations, the Company retains ownership of inventory which is held in third-party contract manufacturing facilities. In certain instances, shipping terms are delivery-at-place and the Company is responsible for arranging transportation and delivery of goods ready for unloading at the named place. In those instances, the Company bears all risk involved in bringing the goods to the named place and records the related inventory in transit to the customer as inventory on the accompanying consolidated balance sheets. In the second quarter of 2022, we closed our facility located in Scottsdale, Arizona where certain of our products were previously manufactured. Inventory is stated at the lower of cost or net realizable value. For items manufactured by our CMs, cost is determined using the weighted average cost method. For items manufactured by third parties, cost is determined using the first-in, first-out method (FIFO). Any adjustments to reduce the cost of inventories to their net realizable value are recognized in earnings in the current period. Write downs for excess and obsolete inventories are estimated based on product life cycles, quality issues, and historical experience. In some instances, the Company holds consigned inventories at its CMs’ locations due to actual or pending customers’ orders. The Company recognized the consigned inventory as an asset in its financial statements
Property and Equipment | Property and Equipment Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, generally three to ten years. The estimated useful lives for leasehold improvements are determined as either the estimated useful life of the asset or the lease term, whichever is shorter. Repairs and maintenance are expensed as incurred. Property and equipment are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. When assets are disposed of (or otherwise sold), the cost and related accumulated depreciation are removed from the accounts and any gain or loss on the disposal of property and equipment is classified as other expense (income) in the Company's consolidated statement of operations.
Goodwill | Goodwill Goodwill represents the excess of cost over fair value of net assets acquired. We account for our goodwill under the authoritative guidance ASC 350 for goodwill and other intangible assets and the provisions of ASU 2017-04, Simplifying the Test for Goodwill Impairment, which we early adopted in fiscal year 2020. Goodwill is not amortized but is tested for impairment annually as of December 31 or more frequently if events or changes in circumstances indicate that our goodwill might be impaired. Such circumstances may include, but not limited to (1) a decline in microeconomic conditions, (2) a significant decline in our financial performance or (3) a significant decline in the price of our common stock for a sustained period of time. We consider the aggregation of the relevant qualitative factors, and conclude whether it is more likely than not that the fair value of our reporting unit is less than the carrying value. If we conclude that it is more likely than not that the fair value of our reporting unit is less than the carrying value, we perform a quantitative impairment test. The quantitative impairment test compares the fair value of the reporting unit to its carrying amount, including goodwill. If the fair value of the reporting unit exceeds the carrying amount of the net assets assigned to that reporting unit, goodwill is not considered impaired. However, if the fair value of the reporting unit is lower than the carrying amount of the net assets assigned to the reporting unit, an impairment charge is recognized equal to the excess of the carrying amount over the fair value. The impairment charge is limited to the goodwill amount of the reporting unit. Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. For the market approach of valuation, we may use the guideline public company method. Under this method we utilize information from comparable publicly traded companies with similar operating and investment characteristics as the reporting unit to derive an indication of value. For the income approach of valuation, we use a discounted cash flow methodology to derive an indication of value, which required management to make estimates and assumptions related to forecasted revenues, gross profit margins, operating income margins, working capital cash flow, income tax rates, EBITDA, perpetual growth rates, and long-term discount rates, among others. In addition, we make certain judgments and assumptions in determining our reporting unit. We base our fair value estimates on assumptions we believe to be reasonable but that are unpredictable and inherently uncertain. Actual future results may differ from those estimates.
Intangibles | Intangibles The Company’s identifiable finite-lived intangible assets are comprised of acquired intangibles, developed technologies, customer relationships and non-compete agreements. The cost of the market-related intangible assets with finite lives is amortized on a straight-line basis over the assets’ respective estimated useful lives. We assess potential impairments to our intangible assets in accordance with the authoritative guidance for impairment or disposal of long-lived assets (ASC 360) when events or changes in circumstances indicate that the carrying value may not be recoverable. We assess the impairment of long-lived and intangible assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. As a first step, we consider factors, which may include the following, but are not limited to: (1) significant underperformance relative to historical or projected future operating results; (2) significant negative industry or economic trends; or (3) a significant decline in our stock price for a sustained period. If this assessment indicates that the carrying value of the assets may not be recoverable, the Company is required to perform the second step to test the asset group for recoverability. This recoverability test compares the future undiscounted cash flows expected from the use of the asset group to its carrying value. If the carrying value is more than the undiscounted future cash flows, the Company is required perform a third step to determine the fair value of the asset group and compare fair value against the carrying value. Any excess carrying value over the fair value needs to be recognized as an impairment loss. Determining the recoverability of long-lived or intangible assets is judgmental in nature and involves the use of significant estimates and assumptions. These estimates and assumptions include revenue growth rates and operating margins used to calculate projected future cash flows and the future market value of our asset group. In addition, we make certain judgments and assumptions in determining our asset group. We base our recoverability estimates on assumptions we believe to be reasonable but that are unpredictable and inherently uncertain. Actual future results may differ from those estimates.
Revenue Recognition | Revenue Recognition Under ASC Topic 606 “Revenue from Contracts with Customers”, the Company recognize revenue when, or as the control of the promised goods or services is transferred to the customers in an amount that reflects the consideration the Company expects to be entitled in exchange for those goods or services. In applying this core principle, the Company performs the following five-steps only when it is probable that substantially all of the consideration that it will be entitled in exchange for the goods or services that will be transferred to the customer: (i) identify the contract(s) with the customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligation(s) in the contract and (v) recognize revenue when or as the entity satisfies performance obligations. A performance obligation is at a point in time, except if it meets any of the three criteria, which will require recognition of revenue over time: • the customer simultaneously receives and consumes the benefit provided by the entity’s performance as the entity performs • the entity’s performance creates or enhances an asset (for example, work in process) that the customer controls as the asset is created or enhanced, and • the entity's performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. Most of the Company's revenue is generated from product sales and the revenue is recognized at a point-in-time when control is transferred to the customer. Each purchase order, along with existing customer agreements, when applicable, represents a contract from a customer and each product sold represents a distinct performance obligation. Revenue is recognized when control is transferred to the customer at a point in time either when the product is shipped to or received by the customer, based on the terms of the specific agreement with the customer, and the Company has an enforceable right to payment for the product. The Company allocates the transaction price, which is generally the quoted price per terms of the contract and the consideration the Company expects to receive, to each performance obligation. The Company offers return rights and/or pricing credits under certain circumstances. We estimate product returns based on historical sales and return trends and record against revenue and corresponding refund liability. A portion of the Company's revenue is recognized over time, including: data subscription, test services or custom design services. Revenue from data subscription plans relate to purchased asset trackers with activated data lines, through a third-party service provider. Data subscription plan revenues are recognized monthly based on the fee stated in the contract, as the customer is simultaneously receiving and consuming the benefits provided throughout the Company's monthly performance obligation. Test service revenues are recognized monthly based on the fee stated in the contract for obligations over time on assets that the customer controls. Design service fees are paid in advance; the prepayments are deferred revenues and are recorded as contract liabilities. Most of the design service fees are recognized based on the Company's achievement of milestones. The Company's performance for the design services does not create an asset with an alternative use to the Company and the Company has an enforceable right to payment for performance completed to date. We recognize from the contract liabilities as milestones are achieved over service periods ranging from three (3) to eighteen (18) months. The Company's contracts with customers do not typically include extended payment terms. Payment terms may vary by contract and type of customer and generally range from 30 to 90 days from delivery. The Company provides assurance-type warranties on all product sales ranging from one to two years. The estimated warranty costs are accrued for at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure. The Company has opted to not disclose the portion of revenues allocated to partially unsatisfied performance obligations, which represent products to be shipped within 12 months under open customer purchase orders, at the end of the current reporting period as allowed under ASC 606. The Company has also elected to record sales commissions when incurred, pursuant to the practical expedient under ASC 340, Other Assets and Deferred Costs, as the period over which the sales commission asset that would have been recognized is less than one year.
Shipping and Transportation Costs | Shipping and Transportation Costs Shipping and other transportation costs expensed as incurred were $0.4 million and $0.5 million for the years ended December 31, 2023 and 2022, respectively. These costs are included in sales and marketing expenses in the accompanying consolidated statements of operations.
Research and Development Costs | Research and Development Costs Research and development costs are expensed as incurred.
Advertising Costs | Advertising Costs Advertising costs are expensed as incurred and were $0.3 million and $0.5 million for the years ended December 31, 2023 and 2022, respectively. These costs are included in sales and marketing expenses in the accompanying consolidated statements of operations.
Income Taxes | Income Taxes The Company records income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. 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. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. When applicable a valuation allowance is established to reduce any deferred tax asset when we determine that it is more likely than not that some portion of the deferred tax asset will not be realized. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest related to unrecognized tax benefits in interest expense and penalties in general and administrative expenses.
Stock-Based Compensation | Stock-Based Compensation We recognize compensation costs related to stock options and restricted stock units granted to employees and directors based on the estimated fair value of the awards on the date of grant. We estimate the option grant fair values, and the resulting stock-based compensation expense, using the Black-Scholes option-pricing model. The grant date fair value of stock-based awards are expensed on a straight-line basis over the requisite service period of the entire reward. The Company recognizes forfeitures when incurred. The assumptions used in the Black-Scholes option-pricing model are as follows: • Fair value of our common stock. The Company’s common stock is valued by reference to the publicly traded price of our common stock. • Expected term. The expected term represents the period of time stock-based awards are expected to be outstanding. • Expected weighted average volatility. From 2018 through 2021, the Company estimated expected volatility using our historical share prices along with volatilities of the selected comparable companies. Beginning 2022, we estimated expected volatility using solely our historical share price volatilities. • Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected term. • Expected dividend. The expected dividend is assumed to be zero as the Company has never paid dividends and have no current plans to pay any dividends.
Fair Value Measurements | Fair Value Measurements The carrying values of the Company’s financial instruments, including cash, trade accounts receivable, accounts payable, accrued liabilities and deferred purchase price obligations approximate their fair values due to the short maturity of these instruments. Fair value measurements are market-based measurements, not entity-specific measurements. Therefore, fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. The Company follows a three-level hierarchy to prioritize the inputs used in the valuation techniques to derive fair values. The basis for fair value measurements for each level within the hierarchy is described below: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable in active markets.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements | Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. This standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. The Company adopted this standard in the first quarter of fiscal 2023; it did not have a material impact on our financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 clarifies classification of franchise taxes, the enacted changes in tax laws or rates and the accounting for transactions that result in a step-up in the tax basis of goodwill. This standard eliminates certain exceptions to the guidance in Topic 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This update is effective for public entities for annual reporting periods and interim periods within those years beginning after December 15, 2020. The adoption of ASU 2019-12 had no impact on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” ASU No. 2023-07 require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity's chief operating decision maker (CODM), amounts and descriptions of other reportable segments, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. The ASU is applicable to entities with a single reportable segment. This ASU is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The ASU should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact of the ASU on our disclosures within the consolidated financial statements. As the amendments apply to the Company's reportable segment disclosures only, the Company does not expect adoption to have a material impact on its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." ASU No. 2023-09 requires expanded disaggregated information about a reporting entity’s effective tax rate reconciliation as well as disclosure of income taxes paid by jurisdiction. The amendments in ASU are effective for fiscal years beginning after December 15, 2024 with early adoption permitted. Retrospective application of the amendments are permitted. The Company will evaluate the ASU to determine its impact on the Company’s disclosures. As the amendments apply to income tax disclosures only, the Company does not expect adoption to have a material impact on its consolidated financial statements. We have assessed all other ASUs issued but not yet adopted and concluded that those not disclosed are not relevant to the Company or are not expected to have a material impact.
