Accounting Policies [Abstract]  
The Company and Summary of Significant Accounting Policies The Company and Summary of Significant Accounting Policies
SiTime Corporation (the “Company”) was incorporated in the State of Delaware in December 2003. The Company is a leading provider of Precision Timing solutions to the global electronics industry, providing the timing functionality that is needed for electronics to operate reliably and correctly. The Company's products have been designed to address a wide range of applications across a broad array of end markets. The Company operates a fabless business model and leverages its global network of distributors to address the broad set of end markets that it serves.
Basis of Presentation
The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). The consolidated financial statements include all adjustments necessary for a fair presentation of our annual results. The Company’s fiscal year begins on January 1 of the year stated and ends on December 31 of the same year. The Company reports its results on a calendar year basis.
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.
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The significant areas requiring the use of management estimates and assumptions include fair value of assets acquired and liabilities assumed in business combinations and estimate of reserve for excess and obsolete inventories. Actual results could differ materially from such estimates. Management believes that the estimates, and judgments upon which they rely, are reasonable based upon information available to them at the time that these estimates and judgments are made.
Foreign Currency Remeasurement
The Company and its wholly-owned subsidiaries use the U.S. dollar as their functional currency. Foreign currency assets and liabilities are remeasured into U.S. dollars at the end-of-period exchange rates except for non-monetary assets and liabilities, which are measured at historical exchange rates. Revenue and expenses denominated in non-U.S. dollars are remeasured using an average exchange rate in effect for the period. Gains or losses from foreign currency remeasurement and transactions are included in other expense, net. For the years ended December 31, 2025, 2024, and 2023, foreign currency remeasurement and transactions gains and losses resulting in a net charge of $0.2 million, $0.8 million, and $0.1 million, respectively.
Cash and Cash Equivalents
Cash and cash equivalents consist of cash balances in the Company’s bank checking and savings accounts and liquid short-term investments with original maturities of 90 days or less at the date of purchase, readily convertible to known amounts of cash.
Fair Value Measurements
The Company determines fair value measurements used in its consolidated financial statements based upon 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. The fair value hierarchy distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs), and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs).
The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:
Level 1:    Valuations based on quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
Level 2:    Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
Level 3:    Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Cash equivalents
At December 31, 2025 and 2024, highly liquid money market funds of $0.4 million and $0.3 million, respectively, were valued using Level 1, of the fair value hierarchy, quoted prices in active markets for identical assets and are included in cash equivalents.
Short-term investments in held-to-maturity securities
As of December 31, 2025, the Company had purchased Treasury Bills with maturities ranging from 3 to 12 months, which the Company intends to hold until maturity and has classified as held-to-maturity securities. The held-to-maturity securities are recorded at amortized cost totaling $791.6 million including gross accrued interest of $7.8 million. As of December 31, 2025, the fair value and gross unrealized gain on the held-to-maturity securities was $792.1 million and $0.5 million respectively. The carrying value of the Company's investments is reviewed quarterly for changes in circumstances or the occurrence of events that suggests an investment may not be fully recoverable. These Treasury Bills were valued using Level 1 of the fair value hierarchy, quoted prices in active markets for identical assets, and are included in short-term investments.
As of December 31, 2024, the Company had purchased Treasury Bills with maturities ranging from 3 to 6 months, which the Company held until maturity and classified as held-to-maturity securities. The held-to-maturity securities were recorded at amortized cost totaling $412.7 million including gross accrued interest of $4.3 million. As of December 31, 2024, the fair value and gross unrealized gain on the held-to-maturity securities was $412.9 million and $0.2 million respectively. The carrying value of the Company's investments is reviewed quarterly for changes in circumstances or the occurrence of events that suggests an investment may not be fully recoverable. These Treasury Bills were valued using Level 1 of the fair value hierarchy, quoted prices in active markets for identical assets, and are included in short-term investments.
Sales based earnout liability
The estimated fair value of the sales based earnout liability is determined using a Monte Carlo simulation model using significant unobservable fair value inputs and is therefore classified as a Level 3 measurement. The assumptions used in the calculation are based on the revenue projections over the term of the contingent earn-out period, expected volatility, and discount rate. The estimates of fair value are uncertain and changes in any of the estimated inputs used as of the date of this report will result in significant adjustments to the fair value. As of December 31, 2025, the Company used a volatility rate of 20%, risk-free rate ranging from 3.4% to 3.7%, and an expected term ranging from 0.1 years to 2.9 years.
The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial liabilities:
Year Ended December 31,
20252024
Beginning fair value$97,256 $103,461 
Change in the fair value during the year recorded to acquisition related costs4,000 6,049 
Payments made during the period(12,903)(12,254)
Ending fair value$88,353 $97,256 
There were no transfers between Level 1, Level 2, and Level 3 categories during any of the periods presented.
Accounts Receivable and Allowances for Credit Losses
Trade accounts receivable are recorded at the invoiced amount, net of allowances for credit losses. An allowance for credit losses is recorded when it is probable that amounts will not be collected based on historical collection trends, age of outstanding receivables, specific customer circumstances, existing economic conditions and future forecasted information. The Company performs periodic credit evaluations of its customers’ financial condition and generally requires no collateral from its customers. Losses have not been significant in any of the periods presented.
Concentration of Credit Risk
Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, short-term investments and accounts receivable. Substantially all of the Company's cash and cash equivalents balances are in excess of Federal Deposit Insurance Corporation insurance limits with financial institutions. Investment policies have been implemented that limit purchases of marketable debt securities to investment-grade securities.
The Company extends credit based on an evaluation of the customer’s financial condition and collateral is not typically required. The Company primarily sells its products through third-party distributors. Two, three and four distributors directly accounted for 10% or more of the Company’s revenue for the year ended December 31, 2025, 2024 and 2023, respectively. No other distributors accounted for 10% or more of the Company's consolidated revenues for the years ended December 31, 2025, 2024, and 2023.

* Accounts receivable from these customers was below 10%.
Inventories
Inventories are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. The Company reduces excess and obsolete inventories to their estimated net realizable value based on management’s assessment of future demand, historical usage by product, and market conditions. Inventory reserve write-downs, once established, are not released until the related inventory has been sold or scrapped.
Property and Equipment
Property and equipment are recorded at cost, less accumulated depreciation. Depreciation of property and equipment is recognized on a straight-line basis over the estimated useful lives of the respective assets as follows:
Lab and manufacturing equipment
3 to 7 years
Computer equipment3 years
Furniture and fixtures5 years
Leasehold improvementsShorter of remaining lease term or estimated useful lives of the assets
Maintenance and repair costs are charged to expense as incurred, and expenditures that extend the useful lives of assets are capitalized. Upon retirement or sale of the property and equipment, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss is recorded in operating expenses.
Intangible Assets
Purchased intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed using the straight-line method over the estimated useful lives of the respective assets of 3 to 10 years. Acquisition-related in-process research and development represents the fair value of incomplete research and development projects that have not reached technological feasibility as of the date of acquisition. Initially, these assets are not subject to amortization. Assets related to projects that have been completed are transferred to developed technology, which are subject to amortization.
Leases
The Company determines if an arrangement is a lease at inception. Lease classification is evaluated at commencement and, as necessary, at modification. Operating lease related balances are included in right-of-use (“ROU”), assets, accrued expenses and other current liabilities, and other non-current liabilities in the Company’s consolidated balance sheets. The Company currently does not have any finance leases.
Operating lease ROU assets represent the Company's right to use an underlying asset for the lease term and operating lease liabilities represent the present value of the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the incremental borrowing rate of the Company, because the interest rates implicit in most of its leases are not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. Operating lease ROU assets also include adjustments related to lease incentives, prepaid or accrued rent and initial direct lease costs. Operating lease ROU assets are subject to evaluation for impairment or disposal on a basis consistent with other long-lived assets.
Lease terms may include periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company generally uses the base, non-cancelable lease term when determining the lease right-of-use assets and lease liabilities. Operating lease cost is recognized on a straight-line basis over the lease term.
The Company has elected the practical expedient within ASC Topic 842 to account for lease and non-lease components as a single lease component. Additionally, the Company has elected the short-term lease exception for all classes of assets and does not recognize ROU assets and lease liabilities for leases with a term of 12 months or less and recognizes lease payments for short-term leases as expense either straight-line over the lease term or as incurred depending on whether the lease payments are fixed or variable. These elections are applied consistently for all leases. Payments under the Company's lease arrangements are primarily fixed, however, certain lease agreements contain variable payments, which are expensed as incurred and not included in the operating lease ROU assets and liabilities. Variable lease payments are primarily comprised of common area maintenance charges and utility costs.
Business Combinations
The Company applies the provisions of ASC 805, Business Combinations (ASC 805), in accounting for acquisitions. ASC 805 requires that the Company evaluates whether a transaction pertains to an acquisition of assets, or to an acquisition of a business. A business is defined as an integrated set of assets and activities that is capable of being conducted and managed for the purpose of providing a return to investors. Asset acquisitions are accounted for by allocating the cost of the acquisition to the individual assets and liabilities assumed on a relative fair value basis; whereas the acquisition of a business requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed at the acquisition date fair values. Goodwill as of the business acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. The Company also evaluates all contingent consideration arrangements to determine if the arrangements are compensatory in nature. No liability is recognized at the acquisition date for arrangements concluded to be compensatory. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the business acquisition date as well as any contingent consideration, where applicable, the estimates are inherently uncertain and subject to refinement. Estimates and assumptions relevant to the determination of the fair value of the assets acquired and liabilities assumed include, but are not limited to, revenue projections, discount rates, and other assumptions. The approach to estimating an initial contingent consideration associated with the purchase price also uses similar unobservable factors such as revenue projections over the term of the contingent earn-out period, discounted for the period over which the initial contingent consideration is measured and expected volatility. Based upon these assumptions, the initial contingent consideration is then valued using a Monte Carlo simulation. As a result, during the measurement period, which may be up to one year from the business acquisition date, the Company may record certain adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of a business acquisition’s measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations. In the event an acquisition involves an entity with which the Company has a preexisting relationship, the Company will recognize a gain or loss, if any, to settle that relationship as of the acquisition date within the consolidated statement of operations and comprehensive loss. All acquisition-related costs are accounted for as expenses in the period in which they are incurred. Changes in the fair value of contingent consideration arrangements that are not measurement period adjustments are recognized in earnings.
Impairment of Goodwill, Intangible Assets, and Other Long-Lived Assets
Goodwill is evaluated for impairment on an annual basis in the fourth quarter of the Company's fiscal year, and whenever events or changes in circumstances indicate the carrying amount of goodwill may not be recoverable. The Company has elected to first assess qualitative factors to determine whether it is more likely than not that the fair value of its single reporting unit is less than its carrying amount, including goodwill. If the Company determines that it is more likely than not that the fair value is less than its carrying amount, then the quantitative impairment test will be performed. Under the quantitative impairment test, if the carrying amount exceeds its fair value, the Company will recognize an impairment loss in an amount equal to that excess but limited to the total amount of goodwill.
The Company evaluates events and changes in circumstances that could indicate carrying amounts of purchased intangible assets and other long-lived assets may not be recoverable. When such events or changes in circumstances occur, it assesses the recoverability of these assets or asset groups by determining whether or not the carrying amount will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset or asset group, the Company records an impairment loss for the amount by which the carrying amount exceeds the fair value of the asset or asset group.
The Company did not recognize any impairment losses on its goodwill, intangible assets, or other long-lived assets during the years ended December 31, 2025, 2024, and 2023.
Warranty
The Company provides limited lifetime warranty coverage on all of its products by guaranteeing that all timing components from the Company will be free from defects in workmanship and materials and will conform to specifications for the life of the system. This assurance-type warranty is not considered a separate performance obligation, and thus no transaction price is allocated to it. The Company records the warranty costs in cost of revenue in the consolidated statements of operations and comprehensive loss. The warranty reserve is calculated using historical claim information to project future warranty claims activity and is recorded within accrued expenses and other current liabilities and other non-current liabilities on the consolidated balance sheets based on the expected timing of the related payments. To date, the
Company has had negligible warranty claims for any defective products, and hence the warranty reserve balances as of December 31, 2025 and 2024 was not significant for any periods presented.
Income Taxes
Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts in the consolidated financial statements of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards, using enacted tax rates in effect for the year in which the 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 earnings in the period that includes the enactment date. A valuation allowance is provided in order to reduce the deferred tax assets to a level which, more likely than not, will be realized.
While the Company believes it has adequately reserved for its uncertain tax positions, no assurance can be given that the final tax outcome of these matters will not be different. The Company adjusts these reserves in light of changing facts and circumstances, such as the closing of a tax audit. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact the provision for income taxes and the effective tax rate in the period in which such determination is made.
The Company recognizes tax positions in the consolidated financial statements only when it is more likely than not that the position will be sustained upon examination by the relevant taxing authority. Liabilities are established for differences between positions taken in a tax return and amounts recognized in the consolidated financial statements. The Company reports interest and penalties related to uncertain tax positions, if any, in the provision for income taxes in the consolidated statements of operations and comprehensive loss. To the extent that accrued interest and penalties do not ultimately become payable, amounts accrued will be reduced and reflected as a reduction of the overall provision for income taxes in the period that such determination is made.
Revenue Recognition
The Company derives revenue from its product sales primarily to distributors, who in turn sell to original equipment manufacturers or other end customers. The Company recognizes product revenue, at a point in time, upon shipment when it satisfies its performance obligations as evidenced by the transfer of control of its products to customers. The software included in our offerings is embedded in the related products, is not sold separately, and does not provide a separate and distinct benefit to the customer. Accordingly, the Company does not identify such software as a separate performance obligation. The Company measures revenue based on the amount of consideration it expects to be entitled to in exchange for products. Variable consideration is estimated and reflected as an adjustment to the transaction price. Depending on the terms of the contract, variable consideration is estimated using either the expected value approach or the most likely value approach. The Company determines variable consideration, which consists primarily of price adjustments and product returns by estimating the amount of consideration the Company expects to receive from its customers based on historical experience of price adjustments and product returns. Changes to the Company’s estimated variable consideration were not material for the periods presented. Since the Company’s performance obligations relate to contracts with a duration of less than one year, it does not disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period.
The Company’s payment terms vary by contract type and type of customer and generally range from 30 to 60 days from shipment. The Company has also elected to recognize the cost for freight and shipping when control over the products sold passes to customers and revenue is recognized.
As a practical expedient, the Company records the incremental costs of obtaining a contract, consisting primarily of sales commissions, when incurred because the amortization period is one year or less. These costs are recorded within selling, general, and administrative expenses.
Cost of Revenue
Cost of revenue consists of wafers acquired from third-party foundries, assembly, packaging, and test cost of the Company’s products paid to third-party contract manufacturers, and personnel and other costs associated with the manufacturing operations of the Company. Cost of revenue also includes depreciation of production equipment, inventory
write-downs, shipping and handling costs, and allocation of overhead and facility costs. The Company also includes credits for rebates received from third-party contract manufacturers in cost of revenue.
Research and Development Expenses
Research and development costs consist primarily of personnel cost, material cost, and facilities related expenses, incurred in the course of planned research and development of new products. Research and development costs are expensed as incurred.
Non-recurring engineering services
The Company has certain contracts to provide non-recurring engineering (NRE) services for research and development arrangements through 2026, which do not meet the requirement to be accounted for under ASC 606, Revenue from Contracts with Customers. The Company recognizes the payments received under these NRE arrangements as liabilities and recognizes them as an offset to research and development expense as the Company achieves the milestones of the contract. As the progress towards completion occurs, the Company uses an input method based on the ratio of costs incurred to date to total estimated costs of the project. Judgment is required to estimate the remaining effort to complete the project. These estimates are reassessed throughout the term of the arrangement. For the years ended December 31, 2025, 2024, and 2023, the Company recorded $1.8 million, $1.5 million and $3.9 million, respectively as a reduction of research and development expenses in the consolidated statements of operations.
Selling, General and Administrative Expenses
Selling, general and administrative expenses primarily consist of personnel costs, field application engineering support, travel costs, professional and consulting fees, accounting and audit fees, legal, advertising expenses, and allocated overhead costs. Selling, general and administrative costs are expensed as incurred. Advertising expenses were $1.3 million, $1.5 million and $1.6 million, for the years ended December 31, 2025, 2024, and 2023, respectively.
Stock-Based Compensation
The Company grants restricted stock unit awards (“RSUs”) of its own common stock. Compensation expense related to share-based transactions is measured at fair value on the grant date. The Company recognizes share-based compensation expense for awards with only service conditions on a straight-line basis over the requisite service period.
Stock-based compensation expense for performance-based restricted stock unit awards ("PRSU") is recognized when it becomes probable that the performance conditions will be met. Stock-based compensation expense for grants with market conditions is valued using a Monte-Carlo simulation model. The Company amortizes stock-based compensation expense for these grants using the graded-vesting method over the requisite performance period. The Company recognizes the expense related to the multi-year performance based restricted stock unit awards ("MYPSU") on a graded-vesting method over the requisite service period.
The Company recognizes forfeitures as they occur.
Net Loss Per Share Attributable to Common Stockholders
Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock and potentially dilutive securities outstanding for the period. Refer to "Note 3 - Net Loss Per Share" for further discussion regarding potentially dilutive and anti-dilutive securities.
Comprehensive Loss
The Company has no components of other comprehensive loss. Therefore, net loss equals comprehensive loss for all periods presented.
Recent Accounting Pronouncements
Recently issued accounting pronouncements not yet adopted
In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40). The ASU requires the disaggregated disclosure of specific expense categories, including purchases of inventory, employee compensation, depreciation, and amortization, within relevant income statement captions. This ASU also requires disclosure of the total amount of selling expenses along with the definition of selling expenses. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Adoption of this ASU can either be applied prospectively to consolidated financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the consolidated financial statements. Early adoption is also permitted. This ASU will likely result in the required additional disclosures being included in our consolidated financial statements, once adopted. We are currently evaluating the provisions of this ASU.
Recently adopted accounting pronouncements
In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Improvements to Income Tax Disclosures (Topic 740). The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024. The Company adopted this guidance on a prospective basis with no material impact on its consolidated financial statements for its Annual Report on Form 10-K for the fiscal year ended December 31, 2025. Refer "Note 9 - Income Taxes" for further details.

Potential dilutive securities include dilutive common shares from share-based awards attributable to the assumed exercise of vested restricted stock units using the treasury stock method. Under the treasury stock method, potential common shares outstanding are not included in the computation of diluted net income per share if their effect is anti-dilutive.
Anti-dilutive potential shares from share-based awards are excluded from the calculation of diluted earnings per share if either their exercise price exceeded the average market price during the period or the share-based awards were determined to be anti-dilutive based on applying the treasury stock method. During the year ended December 31, 2025, 2024, and 2023 the Company had 819,500, 620,889, and 1,078,089 potential shares from share-based awards that are anti-dilutive, respectively. Anti-dilutive potential shares from share-based awards are excluded from the calculation of diluted loss per share for the years ended December 31, 2025, 2024, and 2023 due to the net losses reported in this period.

Commitments and Contingencies Commitments and Contingencies
Purchase Commitments
The Company purchases components from a variety of suppliers and uses several contract manufacturers to provide manufacturing services for its products. During the normal course of business, in order to manage manufacturing lead times and to help ensure adequate component supply, the Company enters into agreements with the Company’s
contract manufacturers and suppliers that allow them to procure inventory based upon criteria as defined by the Company. A portion of the Company’s reported purchase commitments arising from these agreements consists of firm, non-cancelable purchase commitments. In certain instances, these agreements allow the Company the option to cancel, reschedule, and adjust the Company’s requirements based on its business needs prior to when production starts. However, in situations where the Company is unable to cancel, reschedule, or adjust the purchase commitment due to changing customer demand, excess inventories could result in material inventory provisions. Total future non-cancelable purchase commitments as of December 31, 2025 were as follows:

Total$28,056 
Indemnification
The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify other parties to such agreements with respect to certain matters. Typically, these obligations arise in the context of contracts that the Company has entered into, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations and covenants or terms and conditions related to such matters as the sale and/or delivery of its products, title to assets sold, certain intellectual property claims, defective products, specified environmental matters, and certain income taxes. Further, the Company’s obligations under these agreements may be limited in terms of time, amount, or the scope of its responsibility and in some instances, the Company may have recourse against third parties for certain payments made under these agreements. It is not possible to predict the maximum potential amount of future payments under these agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, the Company has had no material indemnification claims under these agreements.
Legal Matters
From time to time, the Company may be a party to various litigation claims in the normal course of business. Legal fees and other costs associated with such actions are expensed as incurred. The Company assesses, in conjunction with legal counsel, the need to record a liability for litigation and contingencies. Accrual estimates are recorded when and if it is determined that such a liability for litigation and contingencies are both probable and reasonably estimable.

The SiTime Corporation 2019 Stock Incentive Plan (the “2019 Plan”) provides for the grant of incentive stock options, non-statutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights, performance stock awards, and other forms of equity compensation (collectively, “stock awards”), and cash awards, all of which may be granted to employees (including officers), directors, and consultants or affiliates. Awards granted under the 2019 Plan vest at the rate specified by the plan administrator, for restricted stock unit awards primarily within the quarter up to five years. As of December 31, 2025, 2.2 million shares were available for future issuance.
SiTime Corporation 2022 Inducement Award Plan
The SiTime Corporation 2022 Inducement Award Plan (the "2022 Plan"), which initially reserved 250,000 shares of the Company's common stock, provides for the grant of incentive stock options, non-statutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights, and other forms of equity compensation and cash awards, all of which may be granted to employees (including officers). Awards granted under the 2022 Plan vest at the rate specified by the plan administrator, for restricted stock unit awards primarily over one to four years. In February 2023, the Company amended and restated the 2022 Plan to reserve an additional 250,000 shares of the Company's common stock. As of December 31, 2025, 176,524 shares were available for future issuance.
Bonus and Retention Plans
On August 4, 2020, the Compensation Committee of the Board adopted and approved the Executive Bonus and Retention Plan (the "Bonus and Retention Plan"). In January 2023 and March 2024, the Compensation Committee approved target bonus amounts and performance goals for the fiscal year 2023 (the “2023 Goals”) and fiscal year 2024 (the "2024 Goals"), respectively. In February 2025, the Compensation Committee approved target bonus amounts based on the achievement of revenue and individual performance goals for the fiscal year 2025 (the "2025 Goals"). The 2023 Goals, 2024 Goals, and 2025 Goals are based on the achievement of revenue and Non-GAAP operating profit, as well as individual performance goals. The awards for the actual payouts are granted in the quarter following the end of the performance period and vest as per the Compensation Committee approval. The target bonuses were granted based on a fixed dollar amount to be settled in RSUs on the vesting date and hence the awards have been classified as liability-based awards until settled. Such expense is included in the non-cash adjustment within stock-based compensation expense on the consolidated cash flow statements. The liability of $5.9 million for the 2025 Goals was recorded as accrued expenses and other current liabilities in the consolidated balance sheet as of December 31, 2025. Actual payouts ranged from 0% to 45% of target for the 2023 Goals, ranged from 170% to 200% of target for the 2024 Goals and 2025 Goals, in each case based on performance.
In April 2022, the Company adopted a bonus plan for certain employees. The target bonuses are granted based on a fixed dollar amount to be settled in RSUs in the quarter following the end of the performance period. Due to the fixed dollar amount targets, the awards have been classified as liability-based awards until settled. Once settled, these awards are reflected as RSUs granted in the table below. Such expense is included in the non-cash adjustment within stock-based compensation expense on the consolidated cash flow statements and was $3.9 million for the year ended December 31, 2025. The liability of $1.1 million was recorded as accrued expenses and other current liabilities in the consolidated balance sheet as of December 31, 2025.
In February 2022, the Compensation Committee of the Company approved and granted to certain of the Company’s executive officers MYPSUs with vesting based on achievement of stock price targets, which are measured based on the 60-trading day average per share closing price of the Company’s common stock on the Nasdaq Global Market during the performance periods of up to six years from the date of grant, subject to the continued service of the grantee through the vest date. The grant-date fair value of each MYPSU was determined using a Monte Carlo simulation model. The assumptions used in the Monte Carlo simulation included expected volatility of 44.4%, risk free rate of 1.83%, no
expected dividend yield, expected term of six years and possible future stock prices over the performance period based on historical stock and market prices. The Company recognizes the expense related to the MYPSUs on a graded-vesting method over the requisite service period. To date, no MYPSUs have vested.
In February 2023 and March 2023, the Compensation Committee of the Company approved PRSUs for the year 2023 with performance goals based on the achievement of revenue over a one year performance period (the “PRSU 2023 Goals”) and achievement of relative total stockholder return with a two year performance period (the "2023 TSR PRSU Goals"). The grant-date fair value of each PRSU with 2023 TSR PRSU Goals was determined using a Monte Carlo simulation model. The assumptions used in the Monte Carlo simulation included expected volatility of 84.0% and 83.8%, risk free rate of 4.67% and 4.05%, no expected dividend yield, and expected term of 1.9 years and 1.8 years for the awards approved in February 2023 and March 2023, respectively. The Company recognizes the expense related to the PRSUs with PRSU 2023 Goals and PRSUs with 2023 TSR PRSU Goals on a graded-vesting method over the requisite performance period. These grants are included in the PRSU awards granted in the table below.
In March 2024 and August 2024, the Compensation Committee of the Company approved PRSUs for the fiscal year 2024 with performance goals based on the achievement of relative total stockholder return with a two year and a three year performance period (the "2024 TSR PRSU Goals"). The grant-date fair value of each PRSU was determined using Monte Carlo simulation model. The assumptions used in the Monte Carlo simulation for the March 2024 awards included expected volatility of 74.7%, risk free rate of 4.5%, no expected dividend yield and expected term of 2.8 years. The assumptions used in the Monte Carlo simulation for the August 2024 awards included expected volatility ranging from 60.5% to 71.9%, risk free rate ranging from 3.9% to 4.3%, no expected dividend yield and expected term ranging from 1.4 years to 2.4 years. The Company recognizes the expense related to the 2024 TSR PRSU Goals on a graded-vesting method over the requisite performance period. These grants are included in the PRSU awards granted in the table below.
In February 2025, the Compensation Committee of the Company approved PRSUs for the fiscal year 2025 with performance goals based on the achievement of relative total stockholder return with a three year performance period (the "2025 TSR PRSU Goals"). The grant-date fair value of each PRSU was determined using Monte Carlo simulation model. The assumptions used in the Monte Carlo simulation for the awards included expected volatility ranging from 72.6% to 72.9%, risk free rate of 4.3%, no expected dividend yield and expected term of 2.9 years. The Company recognizes the expense related to the 2025 TSR PRSU Goals on a graded-vesting method over the requisite performance period. These grants are included in the PRSU awards granted in the table below.

The difference between the number of RSUs vested and the shares of common stock issued during the year ended December 31, 2025 and 2024 is the result of RSUs withheld in satisfaction of minimum tax withholding obligations associated with the vesting. The weighted-average grant date fair value for RSUs granted for the years ended December 31, 2025, 2024, and 2023 was $186.4, $117.0, and $120.1 per share, respectively. The weighted-average grant date fair value for PRSUs granted for the years ended December 31, 2025 and 2024 was $187.8 and $82.8 per share, respectively. No PRSUs were granted for the year ended December 31, 2023. No MYPSUs were granted for the years ended December 31, 2025, 2024, and 2023. The total grant date fair value, as of the vesting date, of awards vested during the years ended December 31, 2025, 2024, and 2023 were $90.6 million, $80.2 million, and $55.6 million, respectively.

Beginning in 2025 annual reporting period, we adopted ASU 2023-09 prospectively. A reconciliation of the U.S. federal statutory income tax rate to our effective tax rate pursuant to the disclosure requirements of ASU 2023-09 for the year ended December 31, 2025 is as follows:

The reported amount of income tax expense differs from an expected amount based on statutory rates primarily due to the Company’s valuation allowance, the stock-based compensation windfall, and the disallowed executive compensation.

As of December 31, 2025 and 2024, based on the available objective evidence, management believes it is more likely than not that the net deferred tax assets will not be realized. Accordingly, management has applied a full valuation allowance against its net deferred tax assets at December 31, 2025 and 2024.
At December 31, 2025 and 2024, the Company has federal net operating loss carry-forwards of approximately $344.3 million and $250.7 million, respectively, and state net operating loss carry-forwards of approximately $85.1 million and $84.5 million, respectively. At December 31, 2025 and 2024, the Company has net operating loss carryforwards for foreign income tax purposes of approximately $0.2 million and $2.0 million, respectively. These federal, state, and foreign net operating loss carry-forwards will expire beginning in 2028.
At December 31, 2025 and 2024, the Company also has federal research and development tax credit carry-forwards of approximately $3.9 million and $3.9 million, respectively, and state research and development tax credit carry-forwards of approximately $3.6 million and $3.6 million, respectively. The federal tax credits begin to expire in 2025, and the California tax credits carry forward indefinitely.
As of December 31, 2025 and 2024, the Company had $2.5 million and $2.5 million of total unrecognized tax benefits. The Company currently has a full valuation allowance against its net deferred tax assets which would impact the timing of the effective tax rate benefit should any of these uncertain tax positions be favorably settled in the future. If the Company is able to eventually recognize these uncertain tax positions, none of the unrecognized benefit would reduce the Company’s effective tax rate due to full valuation allowance of the Company’s deferred tax assets. The Company’s policy is to record interest and penalties related to unrecognized tax benefits as income tax expense. During the years ended December 31, 2025 and 2024, the Company had immaterial amounts related to the accrual of interest and penalties.
A reconciliation of the beginning and ending unrecognized tax benefit amount is as follows:

The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company is subject to examination by federal, state, local, and foreign jurisdictions, where
applicable. Due to the Company’s net losses, its federal, state and local, and foreign tax returns since inception are subject to audit.

Segment Reporting [Abstract]  
Segment Information and Operations by Geographic Area Segment Information and Operations by Geographic Area
The Company operates in one reportable segment related to the design, development, and sale of silicon timing systems solutions. The chief operating decision maker for the Company is the Chief Executive Officer (the "CEO"). The Company’s CEO reviews operating results on an aggregate basis and manages the Company’s operations as a whole for the purpose of evaluating financial performance and allocating resources. Accordingly, the Company has determined that it has a single reportable and operating segment structure.
The CEO uses aggregate net income to allocate resources (including employees, financial, or capital resources) in the annual budgeting and forecasting process and uses that measure as a basis for evaluating financial performance quarterly by comparing the actuals with historical budgets.
The accounting policies of the Company’s single segment are the same as those described in the summary of significant accounting policies within Note 1 of this Annual Report on Form 10-K. The CEO assesses performance for the Company and decides how to allocate resources based on net income that is also reported on the consolidated income statement as net income (loss). The measure of segment assets is reported on the consolidated balance sheets as total assets.
The table below provides information about the Company’s revenue, significant segment expenses and other segment expenses.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
We have established policies and processes for assessing, identifying, and managing material risks from cybersecurity threats. These policies and processes are intended to protect the confidentiality, integrity, and availability of our critical information systems and our critical data, including intellectual property and confidential information that is proprietary, strategic, or competitive in nature (“Information Systems and Data”).
Our IT management team, with oversight by our board of directors (“Board”) and Audit Committee of the Board (“Audit Committee”), helps identify, assess, and manage risks from cybersecurity threats by monitoring and evaluating threats through our cybersecurity risk management program, which leverages the National Institute of Standards and Technology Cybersecurity Framework.
Our cybersecurity risk management program incorporates a variety of methods to manage and mitigate material risks from cybersecurity threats to our Information Systems and Data, including:
•risk assessments designed to help identify cybersecurity risks to our Information Systems and Data;
•a team principally responsible for managing (1) our cybersecurity risk assessment processes, (2) our security controls, and (3) our response to cybersecurity incidents;
•annual training of our employees at all levels and in all departments regarding cybersecurity awareness and protection of confidential information; and
•a cybersecurity incident response plan that includes procedures for detecting and responding to cybersecurity incidents.
Additionally, our cybersecurity risk management program incorporates a variety of tools and services to assess, identify, and manage material risks from cybersecurity threats, including regular network and endpoint monitoring, vulnerability assessments, and penetration testing.
Our cybersecurity risk management program is integrated in our overall enterprise risk management program. For example, our IT team works with management to prioritize our risk management processes and mitigate cybersecurity threats that are more likely to lead to a material impact on our business.
Our cybersecurity risk management program also seeks to manage cybersecurity risks associated with our use of third-party service providers through risk assessments and imposition of contractual obligations.
For a description of risks from cybersecurity threats that may materially affect the Company and how they may do so, see Item 1A “Risk Factors” in this Annual Report on Form 10-K, including the risk factors entitled “Security breaches, cyberattacks, and other disruptions to information technology systems owned or maintained by us or third parties, such as vendors or suppliers, could disrupt our operations, compromise the confidentiality of private customer data or our intellectual property, and adversely affect our business, reputation, operations, and financial results” and “Our business may be impacted by information technology system failures or network disruptions, and lack of redundancy.”

The Company and Summary of Significant Accounting Policies (Policies)
12 Months Ended
Dec. 31, 2025
Accounting Policies [Abstract]  
Basis of Presentation
Basis of Presentation
The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). The consolidated financial statements include all adjustments necessary for a fair presentation of our annual results. The Company’s fiscal year begins on January 1 of the year stated and ends on December 31 of the same year. The Company reports its results on a calendar year basis.
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.
Use of Estimates
Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The significant areas requiring the use of management estimates and assumptions include fair value of assets acquired and liabilities assumed in business combinations and estimate of reserve for excess and obsolete inventories. Actual results could differ materially from such estimates. Management believes that the estimates, and judgments upon which they rely, are reasonable based upon information available to them at the time that these estimates and judgments are made.
Foreign Currency Remeasurement
Foreign Currency Remeasurement
The Company and its wholly-owned subsidiaries use the U.S. dollar as their functional currency. Foreign currency assets and liabilities are remeasured into U.S. dollars at the end-of-period exchange rates except for non-monetary assets and liabilities, which are measured at historical exchange rates. Revenue and expenses denominated in non-U.S. dollars are remeasured using an average exchange rate in effect for the period. Gains or losses from foreign currency remeasurement and transactions are included in other expense, net.
Cash and Cash Equivalents
Cash and Cash Equivalents
Cash and cash equivalents consist of cash balances in the Company’s bank checking and savings accounts and liquid short-term investments with original maturities of 90 days or less at the date of purchase, readily convertible to known amounts of cash.
Fair Value Measurements
Fair Value Measurements
The Company determines fair value measurements used in its consolidated financial statements based upon 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. The fair value hierarchy distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs), and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs).
The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:
Level 1:    Valuations based on quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
Level 2:    Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
Level 3:    Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Cash equivalents
At December 31, 2025 and 2024, highly liquid money market funds of $0.4 million and $0.3 million, respectively, were valued using Level 1, of the fair value hierarchy, quoted prices in active markets for identical assets and are included in cash equivalents.
Short-term investments in held-to-maturity securities
As of December 31, 2025, the Company had purchased Treasury Bills with maturities ranging from 3 to 12 months, which the Company intends to hold until maturity and has classified as held-to-maturity securities. The held-to-maturity securities are recorded at amortized cost totaling $791.6 million including gross accrued interest of $7.8 million. As of December 31, 2025, the fair value and gross unrealized gain on the held-to-maturity securities was $792.1 million and $0.5 million respectively. The carrying value of the Company's investments is reviewed quarterly for changes in circumstances or the occurrence of events that suggests an investment may not be fully recoverable. These Treasury Bills were valued using Level 1 of the fair value hierarchy, quoted prices in active markets for identical assets, and are included in short-term investments.
As of December 31, 2024, the Company had purchased Treasury Bills with maturities ranging from 3 to 6 months, which the Company held until maturity and classified as held-to-maturity securities. The held-to-maturity securities were recorded at amortized cost totaling $412.7 million including gross accrued interest of $4.3 million. As of December 31, 2024, the fair value and gross unrealized gain on the held-to-maturity securities was $412.9 million and $0.2 million respectively. The carrying value of the Company's investments is reviewed quarterly for changes in circumstances or the occurrence of events that suggests an investment may not be fully recoverable. These Treasury Bills were valued using Level 1 of the fair value hierarchy, quoted prices in active markets for identical assets, and are included in short-term investments.
Sales based earnout liability
The estimated fair value of the sales based earnout liability is determined using a Monte Carlo simulation model using significant unobservable fair value inputs and is therefore classified as a Level 3 measurement. The assumptions used in the calculation are based on the revenue projections over the term of the contingent earn-out period, expected volatility, and discount rate. The estimates of fair value are uncertain and changes in any of the estimated inputs used as of the date of this report will result in significant adjustments to the fair value. As of December 31, 2025, the Company used a volatility rate of 20%, risk-free rate ranging from 3.4% to 3.7%, and an expected term ranging from 0.1 years to 2.9 years.
The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial liabilities:
Year Ended December 31,
20252024
Beginning fair value$97,256 $103,461 
Change in the fair value during the year recorded to acquisition related costs4,000 6,049 
Payments made during the period(12,903)(12,254)
Ending fair value$88,353 $97,256 
There were no transfers between Level 1, Level 2, and Level 3 categories during any of the periods presented.
Accounts Receivable and Allowances for Credit Losses
Accounts Receivable and Allowances for Credit Losses
Trade accounts receivable are recorded at the invoiced amount, net of allowances for credit losses. An allowance for credit losses is recorded when it is probable that amounts will not be collected based on historical collection trends, age of outstanding receivables, specific customer circumstances, existing economic conditions and future forecasted information. The Company performs periodic credit evaluations of its customers’ financial condition and generally requires no collateral from its customers. Losses have not been significant in any of the periods presented.
Concentration of Credit Risk
Concentration of Credit Risk
Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, short-term investments and accounts receivable. Substantially all of the Company's cash and cash equivalents balances are in excess of Federal Deposit Insurance Corporation insurance limits with financial institutions. Investment policies have been implemented that limit purchases of marketable debt securities to investment-grade securities.
The Company extends credit based on an evaluation of the customer’s financial condition and collateral is not typically required. The Company primarily sells its products through third-party distributors.
Inventories
Inventories
Inventories are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or net realizable value. The Company reduces excess and obsolete inventories to their estimated net realizable value based on management’s assessment of future demand, historical usage by product, and market conditions. Inventory reserve write-downs, once established, are not released until the related inventory has been sold or scrapped.
Property and Equipment
Property and Equipment
Property and equipment are recorded at cost, less accumulated depreciation. Depreciation of property and equipment is recognized on a straight-line basis over the estimated useful lives of the respective assets as follows:
Lab and manufacturing equipment
3 to 7 years
Computer equipment3 years
Furniture and fixtures5 years
Leasehold improvementsShorter of remaining lease term or estimated useful lives of the assets
Maintenance and repair costs are charged to expense as incurred, and expenditures that extend the useful lives of assets are capitalized. Upon retirement or sale of the property and equipment, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss is recorded in operating expenses.
Intangible Assets
Intangible Assets
Purchased intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed using the straight-line method over the estimated useful lives of the respective assets of 3 to 10 years. Acquisition-related in-process research and development represents the fair value of incomplete research and development projects that have not reached technological feasibility as of the date of acquisition. Initially, these assets are not subject to amortization. Assets related to projects that have been completed are transferred to developed technology, which are subject to amortization.
Leases
Leases
The Company determines if an arrangement is a lease at inception. Lease classification is evaluated at commencement and, as necessary, at modification. Operating lease related balances are included in right-of-use (“ROU”), assets, accrued expenses and other current liabilities, and other non-current liabilities in the Company’s consolidated balance sheets. The Company currently does not have any finance leases.
Operating lease ROU assets represent the Company's right to use an underlying asset for the lease term and operating lease liabilities represent the present value of the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the incremental borrowing rate of the Company, because the interest rates implicit in most of its leases are not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. Operating lease ROU assets also include adjustments related to lease incentives, prepaid or accrued rent and initial direct lease costs. Operating lease ROU assets are subject to evaluation for impairment or disposal on a basis consistent with other long-lived assets.
Lease terms may include periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company generally uses the base, non-cancelable lease term when determining the lease right-of-use assets and lease liabilities. Operating lease cost is recognized on a straight-line basis over the lease term.
The Company has elected the practical expedient within ASC Topic 842 to account for lease and non-lease components as a single lease component. Additionally, the Company has elected the short-term lease exception for all classes of assets and does not recognize ROU assets and lease liabilities for leases with a term of 12 months or less and recognizes lease payments for short-term leases as expense either straight-line over the lease term or as incurred depending on whether the lease payments are fixed or variable. These elections are applied consistently for all leases. Payments under the Company's lease arrangements are primarily fixed, however, certain lease agreements contain variable payments, which are expensed as incurred and not included in the operating lease ROU assets and liabilities. Variable lease payments are primarily comprised of common area maintenance charges and utility costs.
Business Combinations
Business Combinations
The Company applies the provisions of ASC 805, Business Combinations (ASC 805), in accounting for acquisitions. ASC 805 requires that the Company evaluates whether a transaction pertains to an acquisition of assets, or to an acquisition of a business. A business is defined as an integrated set of assets and activities that is capable of being conducted and managed for the purpose of providing a return to investors. Asset acquisitions are accounted for by allocating the cost of the acquisition to the individual assets and liabilities assumed on a relative fair value basis; whereas the acquisition of a business requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed at the acquisition date fair values. Goodwill as of the business acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. The Company also evaluates all contingent consideration arrangements to determine if the arrangements are compensatory in nature. No liability is recognized at the acquisition date for arrangements concluded to be compensatory. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the business acquisition date as well as any contingent consideration, where applicable, the estimates are inherently uncertain and subject to refinement. Estimates and assumptions relevant to the determination of the fair value of the assets acquired and liabilities assumed include, but are not limited to, revenue projections, discount rates, and other assumptions. The approach to estimating an initial contingent consideration associated with the purchase price also uses similar unobservable factors such as revenue projections over the term of the contingent earn-out period, discounted for the period over which the initial contingent consideration is measured and expected volatility. Based upon these assumptions, the initial contingent consideration is then valued using a Monte Carlo simulation. As a result, during the measurement period, which may be up to one year from the business acquisition date, the Company may record certain adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of a business acquisition’s measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations. In the event an acquisition involves an entity with which the Company has a preexisting relationship, the Company will recognize a gain or loss, if any, to settle that relationship as of the acquisition date within the consolidated statement of operations and comprehensive loss. All acquisition-related costs are accounted for as expenses in the period in which they are incurred. Changes in the fair value of contingent consideration arrangements that are not measurement period adjustments are recognized in earnings.
Impairment of Goodwill, Intangible Assets, and Other Long-Lived Assets
Impairment of Goodwill, Intangible Assets, and Other Long-Lived Assets
Goodwill is evaluated for impairment on an annual basis in the fourth quarter of the Company's fiscal year, and whenever events or changes in circumstances indicate the carrying amount of goodwill may not be recoverable. The Company has elected to first assess qualitative factors to determine whether it is more likely than not that the fair value of its single reporting unit is less than its carrying amount, including goodwill. If the Company determines that it is more likely than not that the fair value is less than its carrying amount, then the quantitative impairment test will be performed. Under the quantitative impairment test, if the carrying amount exceeds its fair value, the Company will recognize an impairment loss in an amount equal to that excess but limited to the total amount of goodwill.
The Company evaluates events and changes in circumstances that could indicate carrying amounts of purchased intangible assets and other long-lived assets may not be recoverable. When such events or changes in circumstances occur, it assesses the recoverability of these assets or asset groups by determining whether or not the carrying amount will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset or asset group, the Company records an impairment loss for the amount by which the carrying amount exceeds the fair value of the asset or asset group.
Warranty
Warranty
The Company provides limited lifetime warranty coverage on all of its products by guaranteeing that all timing components from the Company will be free from defects in workmanship and materials and will conform to specifications for the life of the system. This assurance-type warranty is not considered a separate performance obligation, and thus no transaction price is allocated to it. The Company records the warranty costs in cost of revenue in the consolidated statements of operations and comprehensive loss. The warranty reserve is calculated using historical claim information to project future warranty claims activity and is recorded within accrued expenses and other current liabilities and other non-current liabilities on the consolidated balance sheets based on the expected timing of the related payments.
Income Taxes
Income Taxes
Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts in the consolidated financial statements of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards, using enacted tax rates in effect for the year in which the 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 earnings in the period that includes the enactment date. A valuation allowance is provided in order to reduce the deferred tax assets to a level which, more likely than not, will be realized.
While the Company believes it has adequately reserved for its uncertain tax positions, no assurance can be given that the final tax outcome of these matters will not be different. The Company adjusts these reserves in light of changing facts and circumstances, such as the closing of a tax audit. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will impact the provision for income taxes and the effective tax rate in the period in which such determination is made.
The Company recognizes tax positions in the consolidated financial statements only when it is more likely than not that the position will be sustained upon examination by the relevant taxing authority. Liabilities are established for differences between positions taken in a tax return and amounts recognized in the consolidated financial statements. The Company reports interest and penalties related to uncertain tax positions, if any, in the provision for income taxes in the consolidated statements of operations and comprehensive loss. To the extent that accrued interest and penalties do not ultimately become payable, amounts accrued will be reduced and reflected as a reduction of the overall provision for income taxes in the period that such determination is made.
Revenue Recognition
Revenue Recognition
The Company derives revenue from its product sales primarily to distributors, who in turn sell to original equipment manufacturers or other end customers. The Company recognizes product revenue, at a point in time, upon shipment when it satisfies its performance obligations as evidenced by the transfer of control of its products to customers. The software included in our offerings is embedded in the related products, is not sold separately, and does not provide a separate and distinct benefit to the customer. Accordingly, the Company does not identify such software as a separate performance obligation. The Company measures revenue based on the amount of consideration it expects to be entitled to in exchange for products. Variable consideration is estimated and reflected as an adjustment to the transaction price. Depending on the terms of the contract, variable consideration is estimated using either the expected value approach or the most likely value approach. The Company determines variable consideration, which consists primarily of price adjustments and product returns by estimating the amount of consideration the Company expects to receive from its customers based on historical experience of price adjustments and product returns. Changes to the Company’s estimated variable consideration were not material for the periods presented. Since the Company’s performance obligations relate to contracts with a duration of less than one year, it does not disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period.
The Company’s payment terms vary by contract type and type of customer and generally range from 30 to 60 days from shipment. The Company has also elected to recognize the cost for freight and shipping when control over the products sold passes to customers and revenue is recognized.
As a practical expedient, the Company records the incremental costs of obtaining a contract, consisting primarily of sales commissions, when incurred because the amortization period is one year or less. These costs are recorded within selling, general, and administrative expenses.
Cost of Revenue
Cost of Revenue
Cost of revenue consists of wafers acquired from third-party foundries, assembly, packaging, and test cost of the Company’s products paid to third-party contract manufacturers, and personnel and other costs associated with the manufacturing operations of the Company. Cost of revenue also includes depreciation of production equipment, inventory
write-downs, shipping and handling costs, and allocation of overhead and facility costs. The Company also includes credits for rebates received from third-party contract manufacturers in cost of revenue.
Research and Development Expenses
Research and Development Expenses
Research and development costs consist primarily of personnel cost, material cost, and facilities related expenses, incurred in the course of planned research and development of new products. Research and development costs are expensed as incurred.
Non-recurring engineering services
Non-recurring engineering services
The Company has certain contracts to provide non-recurring engineering (NRE) services for research and development arrangements through 2026, which do not meet the requirement to be accounted for under ASC 606, Revenue from Contracts with Customers. The Company recognizes the payments received under these NRE arrangements as liabilities and recognizes them as an offset to research and development expense as the Company achieves the milestones of the contract. As the progress towards completion occurs, the Company uses an input method based on the ratio of costs incurred to date to total estimated costs of the project. Judgment is required to estimate the remaining effort to complete the project. These estimates are reassessed throughout the term of the arrangement. For the years ended December 31, 2025, 2024, and 2023, the Company recorded $1.8 million, $1.5 million and $3.9 million, respectively as a reduction of research and development expenses in the consolidated statements of operations.
Selling, General and Administrative Expenses
Selling, General and Administrative Expenses
Selling, general and administrative expenses primarily consist of personnel costs, field application engineering support, travel costs, professional and consulting fees, accounting and audit fees, legal, advertising expenses, and allocated overhead costs. Selling, general and administrative costs are expensed as incurred.
Stock-Based Compensation
Stock-Based Compensation
The Company grants restricted stock unit awards (“RSUs”) of its own common stock. Compensation expense related to share-based transactions is measured at fair value on the grant date. The Company recognizes share-based compensation expense for awards with only service conditions on a straight-line basis over the requisite service period.
Stock-based compensation expense for performance-based restricted stock unit awards ("PRSU") is recognized when it becomes probable that the performance conditions will be met. Stock-based compensation expense for grants with market conditions is valued using a Monte-Carlo simulation model. The Company amortizes stock-based compensation expense for these grants using the graded-vesting method over the requisite performance period. The Company recognizes the expense related to the multi-year performance based restricted stock unit awards ("MYPSU") on a graded-vesting method over the requisite service period.
The Company recognizes forfeitures as they occur.
Net Loss Per Share Attributable to Common Stockholders
Net Loss Per Share Attributable to Common Stockholders
Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock and potentially dilutive securities outstanding for the period. Refer to "Note 3 - Net Loss Per Share" for further discussion regarding potentially dilutive and anti-dilutive securities.
Comprehensive Income (Loss)
Comprehensive Loss
The Company has no components of other comprehensive loss. Therefore, net loss equals comprehensive loss for all periods presented.
Recently Accounting Pronouncements
Recent Accounting Pronouncements
Recently issued accounting pronouncements not yet adopted
In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40). The ASU requires the disaggregated disclosure of specific expense categories, including purchases of inventory, employee compensation, depreciation, and amortization, within relevant income statement captions. This ASU also requires disclosure of the total amount of selling expenses along with the definition of selling expenses. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Adoption of this ASU can either be applied prospectively to consolidated financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the consolidated financial statements. Early adoption is also permitted. This ASU will likely result in the required additional disclosures being included in our consolidated financial statements, once adopted. We are currently evaluating the provisions of this ASU.
Recently adopted accounting pronouncements
In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Improvements to Income Tax Disclosures (Topic 740). The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods beginning after December 15, 2024. The Company adopted this guidance on a prospective basis with no material impact on its consolidated financial statements for its Annual Report on Form 10-K for the fiscal year ended December 31, 2025. Refer "Note 9 - Income Taxes" for further details.
