The Company considers all short-term, highly liquid investments with an original or a remaining maturity at purchase of ninety days or less to be cash equivalents. The Company’s investment portfolio included in cash equivalents is generally comprised of investments that meet high credit quality standards. The Company’s investment portfolio consists of money market accounts and funds. Restricted cash represents amounts pledged as cash security related to the use of credit cards.

The Company estimates the amount of uncollectible accounts receivable at the end of each reporting period based on the aging of the receivable balance, current and historical customer trends, and communications with its customers. Amounts are written off only after considerable collection efforts have been made and the amounts are determined to be uncollectible.

The Company provides an allowance for doubtful accounts based on both historical experience and a specific identification basis. As of December 31, 2023 and January 1, 2023, the allowance for doubtful accounts was $34 thousand and $18 thousand, respectively, in its consolidated balance sheets. Bad debt expense for the years ended December 31, 2023, January 1, 2023, and January 2, 2022 was $24 thousand, $16 thousand, and $62 thousand, respectively.

Due to the terms in contractual agreements with customers, the timing of revenue recognition may differ from the timing of invoicing to customers, and these timing differences result in accounts receivables, contract assets, or contract liabilities on the Company’s consolidated balance sheets.

The Company records a contract asset when revenue is recognized prior to invoicing if the Company does not have the unconditional right to invoice the customer. The Company records a contract liability (deferred revenue) when revenue is recognized subsequent to invoicing and also when consideration is received in advance of satisfying performance obligations. Balances in contract assets are transferred to accounts receivable when the Company has an unconditional right to invoice the customer. Balances in contract liabilities (deferred revenue) are recognized as revenue once the performance obligations are satisfied, as control of goods and services are transferred to the customer, all revenue recognition criteria have been met, and any constraints have been resolved. Payment terms and conditions vary by term of contracts with the customer. The Company's contracts do not include a significant financing component. The Company's invoicing terms provide customers with simplified and predictable ways of purchasing the Company's goods and services and not to facilitate financing arrangements. The timing between invoicing and when payment is due is not significant. The Company defers costs until related revenue is recognized.

The Company had contract assets associated with eFPGA-related professional services revenue of approximately $3.6 million, $2.0 million, and $0.3 million and contract liabilities (reflected as deferred revenue) associated with eFPGA-related professional services revenue of $1.1 million, $0.3 million, and $0.5 million on the consolidated balance sheets at December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. The Company has concluded that none of the costs it has incurred to obtain and fulfill its ASC 606 contracts during the years ended December 31, 2023 and January 1, 2023 met the capitalization criteria and as such, there are no costs deferred nor recognized as assets on the consolidated balance sheets at December 31, 2023, and January 1, 2023.

The current expected credit loss ("CECL") reserve required under ASU 2016-13 "Financial Instruments - Credit Losses - Measurement of Credit Losses on Financial Instruments (Topic 326)" ("ASU 2016-13"), reflects the Company's current estimate of potential credit losses related to its financing receivables. As of January 1, 2023, the Company's CECL reserve was $0. Subsequent changes to the CECL reserve are recognized through a provision for or reversal of current expected credit loss reserve on the Company's consolidated statement of operations. ASU 2016-13 specifies the reserve should be based on relevant information about past events, including historical loss experience, market conditions, and reasonable and supportable macroeconomic forecasts for the duration of each financing receivable. For each financing receivable, the Company performs an annual quantitative assessment of the impact of CECL using a probability-of-default method. This includes estimating the probability that the loan will default before its maturity (probability of default) and the amount of the loss if the loan defaults (loss given default). These two factors result in an expected loss percentage that is applied to the balance of each financing receivable to determine the expected credit loss. The Company adjusts these factors for current conditions, including the financial condition of the borrower, the probability that it will grant the borrower a concession through modification of the loan terms, and reasonable and supportable forecasts of future losses as necessary.

The Company previously classified certain licensed tooling software as leased assets and liabilities under ROU assets and financing lease liabilities pursuant to lease accounting under ASC 842, Leases. Upon further analysis, the Company determined these amounts are intangible assets subject to amortization in accordance with ASC 350, Intangibles, Goodwill, and Other and financed through financing arrangements. As a result, the Company corrected immaterial errors to revise its financial statements as of January 1, 2023, to present $933 thousand as property and equipment, net instead of a right of use asset, and to present $887 thousand as notes payable instead of finance leases. $616 thousand was incorporated into the Company's accumulated amortization for property and equipment balance as of January 1, 2023.

The statements of cash flows have been revised to present non-cash investing and financing activities of $650 thousand and $690 thousand for property and equipment purchased through financing arrangements during the fiscal years ended January 1, 2023 and January 2, 2022, respectively, previously presented as finance lease obligations. Cash payments on notes payable during the fiscal years ended January 1, 2023 and January 2, 2022 were $452 thousand and $378 thousand, respectively, instead of presented as payments of finance lease obligations. Refer to Note 7 for additional information.

The Company has determined the correction of this error did not have a material impact on the Company's financial statements for any of the periods presented.

Leases

The Company accounts for leases under ASC 842 and related ASUs. Under ASC 842, all significant lease arrangements are generally recognized at the lease commencement date. Right-of-use ("ROU") assets and lease liabilities are recorded in the Company's consolidated balance sheet. The Company determines if an arrangement is a lease at inception. When an arrangement is a lease, the Company determines if it is an operating lease or a finance lease. Lease liabilities represent the present value of the Company's future lease payments over the expected lease term, which includes options to extend or terminate the lease when it is reasonably certain those options will be exercised. The present value of a lease liability is determined using the Company's incremental collateralized borrowing rate at lease inception. ROU assets represent the Company's right to control the use of the leased asset during the lease and are recognized in an amount equal to the lease liability for leases with an initial term greater than 12 months. An ROU asset may also include lease payments related to initial direct costs and prepayments and excludes lease incentives. The Company does not apply lease recognition requirements to lease arrangements having terms of twelve months or less. Instead, it recognizes payments in the consolidated statement of operations as rental costs on a straight-line basis over the lease term. The Company has lease agreements which contain lease and non-lease components; non-lease components are generally accounted for separately.

The Company’s ROU assets were approximately $1 million and $0.5 million and lease liabilities were approximately $1.0 million and $0.5 million on the Company’s consolidated balance sheets at December 31, 2023 and January 1, 2023, respectively. See Note 8 for additional information.

Fair Value of Financial Instruments

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market used to measure fair value:

•

Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

•

Level 2 - Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be derived from observable market data. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, foreign exchange rates, and credit ratings.

•

Level 3 - Unobservable inputs that are supported by little or no market activities.

The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The determination of fair value involves the use of appropriate valuation methods and relevant inputs into valuation models. The carrying value of cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximate their fair values due to their relatively short maturities.

The Company's financial assets consisting of an investment in non-marketable equity without a readily determinable fair value are measured under a measurement election alternative to the requirement to carry equity interests at fair value. In the Fiscal Year ended January 2, 2022, the Company recognized revenue from a contractual arrangement with an unaffiliated customer on the sale of eFPGA IP. The eFPGA IP included an eFPGA intellectual property license, know-how, and eFPGA-related professional services. Consideration in the contractual arrangement was comprised of cash and non-cash consideration. Non-cash consideration consisted of shares of common stock in the customer. The customer was, and continues to be, a privately-held company and its common stock is not publicly traded. The Company applied significant judgement to estimate the fair value of the shares as a portion of the total contractual consideration. The Company recognized a $0.3 million non-marketable equity investment on its consolidated balance sheet and a corresponding amount in deferred revenue. This deferred revenue was recognized as revenue during the year ended January 1, 2023.

In determining the fair value of the investment at acquisition of the common stock, the Company applied the Black-Scholes Option Pricing model using a back-solve technique and applied significant judgment to quantify inputs used in the model, in accordance with the AICPA Accounting and Valuation Guide, Valuation of Privately Held Company Equity Securities Issued as Compensation (2013). The Company has neither significant influence nor control over the investee. Post-acquisition, the Company accounts for the non-marketable equity investment under a practical expedient under ASC 321, in which equity investments without a readily determinable fair value are measured to fair value at “cost minus impairment.” Under the “cost minus impairment” method, when the non-marketable equity investment is determined to be impaired on the basis of a qualitative assessment, the carrying value of the non-marketable equity security is adjusted to fair value and is measured at cost, less any impairment. The Company reviews its non-marketable equity investment for impairment periodically. The carrying value of non-marketable equity securities is classified within Level 3 of the fair value hierarchy. Any losses, should they occur, from impairments of non-marketable equity investments are recorded in the statements of operations within interest income and other (expense) income, net. The non-marketable equity investment is classified as a non-current asset on the consolidated balance sheets. There was no impairment assessed as of December 31, 2023 and January 1, 2023. See Note 9 for additional information.

Cost of Revenues

The Company records costs of revenue associated with hardware product revenues, eFPGA IP revenue, and SaaS revenue. Hardware product costs include the cost of materials, contract manufacturing fees, shipping costs, and quality assurance. Hardware product costs also include indirect costs such as warranty, excess and obsolete inventory charges, general overhead costs, and depreciation and amortization of certain capitalized software. eFPGA IP and SaaS costs include costs related to services under contractual agreements over the term of their respective agreements. These costs are primarily comprised of employee salary and benefits and other employee-related costs to perform work on revenue-generating contracts with customers, software tool utilization costs, and contract engineering costs.

Hardware Product Warranty Costs

The Company warrants product hardware against defects in material and workmanship under normal use for twelve months from the date of shipment. The Company’s liability is limited to the cost of repair or replacement of the defective part. The Company does not consider activities related to such warranties to be a separate performance obligation under ASC 606. The terms and conditions of sale generally do not allow for refunds or product returns other than for warranty repairs. The Company does not have significant product warranty-related costs or liabilities for the years ended December 31, 2023, January 1, 2023, and January 2, 2022.

Foreign Currency Transactions

All of the Company’s revenue transactions and inputs to its cost of revenue are denominated in U.S. dollars. The Company conducts sales and marketing activities in various countries outside of the United States. The Company's foreign operations' monetary assets and liabilities are translated into U.S. dollars at current period-end exchange rates and non-monetary assets and related elements of expense are translated using historical exchange rates. The Company's foreign operations' income and expenses are transacted in local foreign currency and translated to U.S. dollars using the average exchange rates in effect during the period. Gains and losses from the foreign currency transactions of the Company's foreign operations are recorded as interest income and other (expense) income, net in the consolidated statements of operations. The impact from foreign currencies was not significant for each of the Fiscal Years ended December 31, 2023, January 1, 2023, and January 2, 2022.

Operating expenses denominated in foreign currencies represented approximately 8%, 12%, and 14% of total operating expenses for the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively. The Company incurred a majority of such foreign currency expenses in India, the United Kingdom, China, Taiwan, and Japan in the Fiscal Years ended December 31, 2023, January 1, 2023, and January 2, 2022. The Company does not use derivative financial instruments to hedge its exposure to fluctuations in foreign currency and therefore, is susceptible to fluctuations in foreign exchange gains or losses in its results of operations in future reporting periods.

Advertising

Advertising and promotion expenses are charged to “selling, general, and administrative” expense in the consolidated statements of operations as incurred. Advertising and promotion expenses were $44 thousand, $40 thousand, and $47 thousand for the years ended December 31, 2023, January 1, 2023, and January 2, 2022, respectively.

The Company grants stock-based compensation under its stock plan (the "Plan") to eligible employees and non-employee directors and grants stock-based compensation under an employee stock purchase plan ("ESPP") for all eligible employees. The Company accounts for stock-based compensation under the provisions of the amended authoritative guidance and related interpretations, which require the measurement and recognition of expense related to the fair value of stock-based compensation awards. The fair value of stock-based compensation awards is measured at the grant date and re-measured upon modification, as appropriate. The Company uses the Black-Scholes option pricing model to estimate the fair value of employee stock options and rights to purchase shares. The fair value of restricted stock awards, restricted stock units, and performance-based restricted stock units is based on the closing price of the Company’s common stock on the date of grant.

Using the Black-Scholes pricing model requires the Company to develop highly subjective assumptions, including the expected term of awards, expected volatility of its stock, expected risk-free interest rate, and expected dividend rate over the term of the award. The expected term of awards is based primarily on the Company's historical experience with similar grants. The expected stock price volatility for both stock options and ESPP shares is based on the historic volatility of the Company's stock, using the daily average of the opening and closing prices, and measured using historical data appropriate for the expected term. The risk-free interest rate assumption approximates the risk-free interest rate of a Treasury Constant Maturity bond with a maturity appropriate for the expected term of stock awards under the Plan or the maturity appropriate for the term of the purchase period for the ESPP Plan. The dividend yield assumption is based on the Company's intent not to issue a dividend under its dividend policy. This fair value is expensed over the requisite service period of the award.

Stock-based compensation expense is measured at the grant date based on the fair value of the award less expected forfeitures, over the requisite service period, which is typically the vesting period. Expected forfeitures are an estimate based on the historical pre-vest cancellation experience and is applied to all share-based awards. Equity compensation awards that contain a service condition are expensed using the straight-line attribution method over the requisite service period. Performance-based awards are expected to vest based on the achievement of a performance goal and are expensed over the estimated vesting period, which is estimated by management. The Company regularly reviews the assumptions used to compute the fair value of its stock-based awards and it revises its assumptions as appropriate. See Notes 11 and 12 for additional information.

The Company's interest income is comprised of interest earned on its money market accounts and financing receivables. As of December 31, 2023, the Company had one note receivable related to the conversion of accounts receivable for a customer. Interest is accrued as earned and is reflected as an increase in the balance of the note receivable, as well as recognized as interest income on the Company's consolidated statement of operations. All accrued and unpaid interest will be due and payable to the Company on the maturity date of the note receivable. Refer to Note 9 for additional information.

As part of the process of preparing the Company's financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it operates. This process involves estimating the Company's actual current tax exposure together with assessing temporary differences resulting from different tax and accounting treatment of items, such as deferred revenue, allowance for doubtful accounts, the impact of equity awards, depreciation and amortization, and employee-related accruals. These differences result in deferred tax assets and liabilities, which are included on the Company's balance sheets. The Company must then assess the likelihood that its deferred tax assets will be recovered from future taxable income. To the extent the Company believes that recovery is not likely, it must establish a valuation allowance. To the extent the Company establishes a valuation allowance or increases this allowance in a period, it must include an expense within the tax provision in the statements of operations.

The Company accounts for uncertainty in income taxes using a two-step approach for recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. The Company classifies the liability for unrecognized tax benefits as current to the extent that it anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for (benefit from) income taxes. Accrued interest and penalties are included within the accrued liabilities in the consolidated balance sheets.

The net income (loss) in the consolidated statements of operations for each of the years ended December 31, 2023, January 1, 2023, and January 2, 2022 is the same as the consolidated comprehensive income (loss).

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash and cash equivalents and accounts receivable. Cash and cash equivalents are maintained with high-quality institutions. The Company’s accounts receivables are denominated in U.S. dollars and are derived primarily from sales to customers located in North America, Europe and Asia Pacific. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. See Note 14 for information regarding concentrations associated with accounts receivable.

The Company depends on a limited number of contract manufacturers, subcontractors, and suppliers for wafer fabrication, assembly, programming and testing of its hardware products and for the supply of programming equipment. These services are typically provided by one supplier for each of the Company’s hardware products. The Company generally purchases these single or limited source services through standard purchase orders. Since the Company relies on independent subcontractors to perform these services, it cannot directly control its product delivery schedules, costs, or quality levels. The Company’s future success also depends on the financial viability of its independent subcontractors.

When the Company acquires a business, it allocates the purchase price to the acquired tangible assets and assumed liabilities, including deferred revenue, liabilities associated with the fair value of contingent consideration, and acquired identifiable intangible assets with finite lives. Any residual purchase price is recorded as goodwill. The allocation of the purchase price requires the Company to make significant estimates in determining the fair values of these acquired assets and assumed liabilities, intangible assets with finite useful lives, and goodwill. These estimates are based on information obtained from management of the acquired companies, the Company's assessment of this information, and historical experience. These estimates can include, but are not limited to, the cash flows that an acquired business is expected to generate in the future, the cash flows that specific assets acquired with that business are expected to generate in the future, the appropriate weighted average cost of capital, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable, and if different estimates were used, the purchase price for the acquisition could be allocated to the acquired assets and assumed liabilities differently from the allocation that the Company has made to the acquired assets and assumed liabilities. In addition, unanticipated events and circumstances may occur that may affect the accuracy or validity of such estimates, and if such events occur, the Company may be required to adjust the value allocated to acquired assets or assumed liabilities and may impact the useful life assigned to intangible assets with finite useful lives, which would impact amortization expense of intangible assets with finite useful lives and results of operations.

The Company recognizes assets acquired (including goodwill and identifiable intangible assets with finite useful lives) and liabilities assumed at fair value on the acquisition date. Subsequent changes to the fair value of such assets acquired and liabilities assumed are recognized in earnings, after the expiration of the measurement period, a period not to exceed 12 months from the acquisition date. Acquisition-related expenses and acquisition-related restructuring costs are recognized in earnings in the period in which they are incurred.
