INDEX TO FINANCIAL STATEMENTS ​ Page Report of Independent Registered Public Accounting Firm (PCAOB ID 42 ) 42 Financial Statements: ​ Balance Sheets 44 Statements of Income and Comprehensive Income 45 Statements of Stockholders’ Equity 46 Statements of Cash Flows 47 Notes to Financial Statements 48 ​ ​ ​ ​ ​ ​ ​ ​ 41 Table of Contents ​ REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Stockholders and the Board of Directors of Everspin Technologies, Inc. Opinion on the Financial Statements ​ We have audited the accompanying balance sheets of Everspin Technologies, Inc. (the Company) as of December 31, 2022 and 2021, the related statements of income and comprehensive income, stockholders’ equity, and cash flows for each of the two years in the period ended December 31, 2022, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for the years then ended, in conformity with U.S. generally accepted accounting principles. ​ Basis for Opinion ​ These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. ​ We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. ​ Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. ​ Critical Audit Matter ​ The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosures to which it relates. ​ ​ 42 Table of Contents Accounting for Inventory ​ ​ ​ ​ ​ ​ Description of the Matter ​ As discussed in Note 2 to the financial statements, Inventory is valued at the lower of cost or net realizable value using the first-in, first-out method. At December 31, 2022 the Company’s inventory balance was $6.7 million. ​ Auditing the Company's accounting for inventory was challenging and complex primarily due to the high volume of transactions and multiple data sources involved in the initiation, processing, and recording of inventory transactions. The data sources include information received from the Company’s several third-party suppliers involved in the manufacturing process. ​ How We Addressed the Matter in Our Audit ​ To test the Company’s accounting for inventory, we performed audit procedures that included, among others, performing physical observation and direct confirmations of inventory held at third-party suppliers, and testing a sample of inventory transactions and manufacturing costs incurred during the year to evaluate the cost of inventory. ​ /s/ Ernst & Young LLP We have served as the Company’s auditor since 2008.

Notes to Financial Statements 1. Organization and Operations Everspin Technologies, Inc. (the Company) was incorporated in Delaware on May 16, 2008. The Company’s magnetoresistive random access memory (MRAM) solutions offer the persistence of non-volatile memory with the speed and endurance of random access memory (RAM) and enable the protection of mission critical data particularly in the event of power interruption or failure. The Company’s MRAM solutions allow its customers in key markets, such as industrial, medical, automotive/transportation, aerospace, and data center, to design high performance, power-efficient and reliable systems without the need for bulky batteries or capacitors. 2. Summary of Significant Accounting Policies Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates, including those related to revenue recognition, fair value of assets and liabilities, inventory net realizable value, product warranty reserves, deferred tax assets and related valuation allowances, and stock-based compensation. The Company believes its estimates and assumptions are reasonable; however, actual results may differ from the Company’s estimates. Segments The Company’s chief operating decision maker is its Chief Executive Officer who reviews financial information for purposes of allocating resources and evaluating financial performance for the entire Company. As a result, the Company has single operating and reportable segment. Cash and Cash Equivalents The Company considers all highly liquid, short-term investments with maturity dates of 90 days or less at the date of purchase to be cash equivalents. The Company’s cash equivalents consist solely of money market funds. Accounts Receivable, Net Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company generally does not require collateral or other security in support of accounts receivable. Allowances would be provided for individual accounts receivable when the Company becomes aware of a customer’s inability to meet its financial obligations, such as in the case of bankruptcy, deterioration in the customer’s operating results or change in financial position. If circumstances related to customers change, estimates of the recoverability of receivables would be further adjusted. The Company also considers a number of factors in evaluating the sufficiency of its allowance for doubtful accounts, including the length of time receivables are past due, significant one-time events, creditworthiness of customers and historical experience. Account balances would be charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company’s evaluation determined that no material allowance for doubtful accounts was necessary at December 31, 2022 and 2021. The unbilled accounts receivable is an estimate of consideration to which the Company expects to be entitled for uses of the Company’s intellectual property. Certain customers report on a lagged basis and actual information is not available timely. The estimates recorded are based on historical trends in the customer’s usage and current market conditions. At December 31, 2022 and 2021, the unbilled accounts receivable balance was $ 551,000 and $ 450,000 , respectively. ​ The Company establishes an allowance for product returns. The Company analyzes historical returns, current economic trends and changes in customer demand and acceptance of products when evaluating the adequacy of sales returns. Returns are processed as credits on future purchases and, as a result, the allowance is recorded against the 48 Table of Contents balance of trade accounts receivable. In addition, the Company from time to time may establish an allowance for estimated price adjustments related to its distributor agreements. The Company estimates credits to distributors based on the historical rate of credits provided to distributors relative to sales and evaluation of current market conditions. At December 31, 2022 and 2021, the allowance for product returns and price adjustments was $ 384,000 and $ 397,000 , respectively. Accounts receivable, net consisted of the following (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ 2022 ​ 2021 Trade accounts receivable ​ $ 10,498 ​ $ 8,140 Unbilled accounts receivable ​ ​ 551 ​ ​ 450 Allowance for product returns and price adjustments ​ ​ ( 384 ) ​ ​ ( 397 ) Accounts receivable, net ​ $ 10,665 ​ $ 8,193 ​ Concentration of Credit Risk Financial instruments that potentially expose the Company to a concentration of credit risk consist principally of cash and cash equivalents that are held by a financial institution in the United States and accounts receivable. Amounts on deposit with a financial institution may at times exceed federally insured limits. The Company maintains its cash accounts with high credit quality financial institutions and accordingly, minimal credit risk exists with respect to the financial institutions. Significant customers are those which represent more than 10% of the Company’s total revenue or net accounts receivable balance at each respective balance sheet date. For the purposes of this disclosure, the Company defines “customer” as the entity that is purchasing the products or licenses directly from the Company, which includes the distributors of the Company’s products in addition to end customers that the Company sells to directly. For each significant customer, revenue as a percentage of total revenue and accounts receivable as a percentage of total accounts receivable, net are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenue ​ Accounts Receivable ​ Year Ended December 31, ​ December 31, Customers 2022 2021 2022 2021 Customer A 18 % 22 % ​ 30 % 54 % Customer B 15 % * % ​ 18 % * % Customer C 11 % * % ​ * % * % * Less than 10% Inventory Inventory is valued at the lower of cost, using the first-in, first-out or net realizable value. The carrying value of inventory is adjusted for excess and obsolescence based on the Company’s evaluation which takes into consideration historical and expected future demand, the effect new products may have on the sale of existing products, technological obsolescence, and other factors including inventory age and shipment. At the point of loss recognition, a new lower cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in that new cost basis. Fair Value of Financial Instruments Fair value is defined as 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. The framework for measuring fair value provides a three-tier hierarchy prioritizing inputs to valuation techniques used in measuring fair value as follows: Level 1 — Observable inputs such as quoted prices for identical assets or liabilities in active markets; 49 Table of Contents Level 2 — Inputs, other than quoted prices for identical assets or liabilities in active markets, which are observable either directly or indirectly; and Level 3 — Unobservable inputs in which there is little or no market data requiring the reporting entity to develop its own assumptions. The carrying value of accounts receivable, accounts payable, and other accruals readily convertible into cash approximate fair value because of the short-term nature of the instruments. As of December 31, 2022, based on Level 2 inputs and the borrowing rates available to the Company for loans with similar terms and consideration of the Company’s credit risk, the carrying value of the Company’s variable interest rate debt, excluding unamortized debt issuance costs, approximates fair value. The Company’s financial instruments consist of Level 1 assets and a Level 3 liability. Where quoted prices are available in an active market, securities are classified as Level 1. Level 1 assets consist of highly liquid money market funds that are included in cash equivalents. The Company’s Level 3 liability consists of warrants issued in connection with the 2019 Credit Facility (as defined in Note 6). The change in the fair value of the warrant liability during the year ended December 31, 2022 was immaterial. The following tables sets forth the fair value of the Company’s financial assets and liabilities measured at fair value on a recurring basis (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2022 ​ Level 1 Level 2 Level 3 Total Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ Money market funds ​ $ 26,812 $ — $ — $ 26,812 Total assets measured at fair value ​ $ 26,812 $ — $ — $ 26,812 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ Warrant liability ​ $ — $ — $ 27 $ 27 Total liabilities measured at fair value ​ $ — $ — $ 27 $ 27 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ Level 1 Level 2 Level 3 Total Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ Money market funds ​ $ 21,508 $ — $ — $ 21,508 Total assets measured at fair value ​ $ 21,508 $ — $ — $ 21,508 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ Warrant liability ​ $ — $ — $ 50 $ 50 Total liabilities measured at fair value ​ $ — $ — $ 50 $ 50 ​ Property and Equipment Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation begins at the time the asset is placed in service. Maintenance and repairs are charged to operations as incurred. Depreciation is computed using the straight-line method over the following estimated useful lives of the assets: ​ ​ ​ ​ ​ Useful Lives Computer and network equipment ​ 2 years Manufacturing equipment ​ 2 – 7 years Furniture and fixtures ​ 7 years Software ​ 3 years Leasehold improvements ​ Lesser of useful life of the asset or the remaining lease term ​ Costs incurred to develop software for internal use during the application development phase are capitalized and amortized over such software’s estimated useful life. Costs related to the design or maintenance of internal-use software are included in operating expenses as incurred. Upon sale or retirement of assets, the cost and related accumulated depreciation are removed from the balance sheet and any resulting gain or loss is reflected in operations. Amortization expense of assets acquired through finance leases is included in the statements of income and comprehensive income. 50 Table of Contents Impairment of Long-lived Assets The Company evaluates its long-lived assets, including property and equipment, at the asset group level, for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. If such events or changes in circumstances occur, for purposes of this assessment, long-lived assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability of these assets is measured by comparison of the carrying amount of each asset group to the future undiscounted cash flows the asset group is expected to generate over its remaining life. If the asset group is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. There have been no impairments of the Company’s long-lived assets during either of the periods presented. Leases The Company leases office, lab, manufacturing space and equipment in various locations with initial lease terms of up to seven years . These leases require monthly lease payments that may be subject to annual increases throughout the lease term. The terms of these leases also include renewal options at the election of the Company to renew or extend the lease for a range of an additional two to five years . These optional periods have not been considered in the determination of the right-of-use-assets (ROU) or lease liabilities associated with these leases as the Company did not consider it reasonably certain it would exercise the options. The Company determines if an arrangement is a lease at inception. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The classification of the Company’s leases as operating or finance leases along with the initial measurement and recognition of the associated ROU assets and lease liabilities is performed at the lease commencement date. The measurement of lease liabilities is based on the present value of future lease payments over the lease term. The Company uses its incremental borrowing rate, based on the information available at commencement date, to determine the present value of lease payments when its leases do not provide an implicit rate. The Company uses the implicit rate when readily determinable. The ROU asset is based on the measurement of the lease liability, includes any lease payments made prior to or on lease commencement and excludes lease incentives and initial direct costs incurred, as applicable. Lease expense for the Company’s operating leases is recognized on a straight-line basis over the lease term. Amortization expense for ROU assets associated with finance leases is recognized on a straight-line basis over the shorter of the useful life of the asset or the lease term and interest expense associated with finance leases is recognized on the balance of the lease liability using the effective interest method based on the estimated incremental borrowing rate. The Company has lease agreements with lease and non-lease components. The Company has elected to not separate lease and non-lease components for any leases involving real estate and office equipment classes of assets and, as a result, accounts for the lease and non-lease components as a single lease component. The Company has elected to separate lease and non-lease components for any leases involving manufacturing facility classes of assets. Further, the Company elected the short-term lease exception policy, permitting it to not apply the recognition requirements of this standard to leases with terms of 12 months or less (short-term leases) for all classes of assets. As of December 31, 2022, the Company did not have any short-term leases. Operating leases are included in right-of-use assets, lease liabilities, and lease liabilities, net of current portion in the Company’s balance sheet. Finance leases are immaterial. Debt Issuance Costs The Company defers and amortizes issuance costs, underwriting fees, end of term payments, and related expenses incurred in connection with the issuance of debt instruments using the effective interest method over the terms of the respective instruments. Debt issuance costs are reflected as a direct reduction of the carrying amount of the related debt liability. 51 Table of Contents Revenue Recognition The Company recognizes revenue when a customer obtains control of the promised products or services, in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue is recognized net of allowances for returns and price adjustments, and any taxes imposed on specific revenue-producing transactions, which are subsequently remitted to governmental authorities. Nature of Products and Services The Company’s revenue is derived from the sale of MRAM-based products in discrete unit form, licenses of and royalties on its MRAM and magnetic sensor technology, the sale of backend foundry services and design services to third parties. Sales of products in discrete unit form are recognized at a point in time, revenue related to licensing agreements is recognized when the Company has delivered control of the technology, revenue related to royalty agreements is recognized in the period in which sales generated from products sold using the Company’s technology occurs, sales of backend foundry services are recognized over time, and design services to third parties are recognized either at a point in time or over time, depending on the nature of the services. Product Revenue For products sold in their discrete form, the Company either sells its products directly to original equipment manufacturers (OEMs), original design manufacturers (ODMs) and contract manufacturers (CMs), or through a network of distributors, who in turn sell to those customers. For sales directly to OEMs, ODMs and CMs, revenue is recognized when the OEM, ODM or CM obtains control of the product, which occurs at a point in time, generally upon shipment to the customer. Contracts for sales of products are generally less than one year. From time to time, the Company may provide distributors with price adjustments subsequent to the delivery of product to them and such amounts are dependent on the end customer and product sales price. Price adjustments can be based on a variety of factors, including customer, product, quantity, geography, and competitive differentiation. Price protection rights grant distributors the right to a credit in the event of declines in the price of the Company’s products. Under these circumstances, the Company remits back to the distributor a portion of their original purchase price after the resale transaction is completed in the form of a credit against the distributors’ outstanding accounts receivable balance. The credits are on a per unit basis and are not given to the distributor until the distributor provides information regarding the sale to their end customer. The Company estimates these credits and record such estimates in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of an allowance for price adjustments for amounts due to distributors. The Company estimates credits to distributors based on the historical rate of credits provided to distributors relative to sales and evaluation of current market conditions. Revenue on shipments to distributors is recorded when control of the products has been transferred to the distributor. The Company estimates the amount of our product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized. The Company estimates its product return liability by analyzing its historical returns, current economic trends and changes in customer demand and acceptance of products. The Company has received insignificant returns to date and believes that returns of its products will continue to be minimal. Upon the transfer of control, generally at shipment, the Company records a trade receivable for the selling price as there is a legally enforceable obligation of the distributor to pay for the product delivered, an allowance is recorded for the estimated discount that will be provided to the distributor, and the net of these amounts is recorded as revenue on the statements of income and comprehensive income. License Revenue For licenses of technology, recognition of revenue is dependent upon whether the Company has delivered rights to the technology, and whether there are future performance obligations under the contract. In some instances, the license agreements call for future events or activities to occur in order for milestones amounts to become due from the customer. The terms of such agreements include payment to the Company of one or more of the following: non-refundable upfront fees; and royalties on net sales of licensed products. Historically, these license agreements have not included other future performance obligations for the Company once the license has been transferred to the customer. 52 Table of Contents Revenue from non-refundable upfront payments is recognized when the license is transferred to the customer and the Company has no other performance obligations. The Company entered into a contractual agreement with a customer in 2021 for the development of a RAD-Hard product, consisting of a technology license, a design license agreement and development contract, and a separate contractual agreement with a customer in 2022 for the development of a strategic radiation hardened field programmable gate array product, consisting of a technology license to provide design and development services under the contractual agreement. The Company applies a five-step approach in determining the amount and timing of revenue to be recognized: (1) identifying the contract with a customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligations in the contract; and (5) recognizing revenue when the performance obligation is satisfied. ​ The Company concluded these contractual arrangements represent one arrangement and evaluated its promises to the customer and whether the performance obligations granted under the arrangement were distinct. The licenses provided to the customer are not transferable, are of limited value without the promised development services, and the customer cannot benefit from the license agreements without the specific obligated services in the development subcontract, as there is strong interdependency between the licenses and the development subcontract. Accordingly, the Company determined the licenses were not distinct within the context of the contract and combined the license with other performance obligations. ​ As a result, the Company is recognizing revenue related to the performance obligations over the duration of the contract using the input method based on costs incurred to date relative to the total expected costs of the contract over the contract period. ​ Patents In an effort to monetize on its intellectual property, the Company may sell patents to customers. The performance obligations are satisfied at the point in time at which the customer obtains control of the patents. Royalties Revenue from sales-based royalties from licenses of the Company’s technology are recognized at the later of when (1) the sale occurs or (2) the performance obligation to which some or all of the sales-based royalty has been allocated is satisfied (in whole or in part). The Company will record an unbilled receivable (within accounts receivable, net) for the portion of sales-based royalties that have been earned, but not invoiced at the end of each reporting period. Other Revenue For certain revenue streams, the Company recognizes revenue based on the pattern of transfer of the services. The Company uses the input method of measuring costs incurred to date compared to total estimated costs to be incurred under the contract as this method most faithfully depicts its performance. The Company will record an unbilled receivable (within accounts receivable, net) for the portion of the work that has been completed but not invoiced at the end of each reporting period. At the inception of each agreement that includes milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price by using the most likely amount method. If it is probable that a significant reversal of cumulative revenue would not occur, the associated milestone value is included in the transaction price. At the end of each subsequent reporting period, the Company re-evaluates the probability or achievement of each such milestone and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment. 53 Table of Contents Product Warranty The Company generally sells products with a limited warranty of product quality and a limited indemnification of customers against intellectual property infringement claims related to the Company’s products. The Company accrues for known warranty and indemnification issues if a loss is probable and can be reasonably estimated and accrues for estimated losses incurred for unidentified issues based on historical experience. A warranty liability was not recorded at December 31, 2022 and 2021, as the estimated future warranty costs were not material based on the Company’s historical experience. Research and Development Research and development expenses are incurred in support of internal development programs or as part of the Company’s joint development agreement with GLOBALFOUNDRIES (see Note 10). Research and development expenses include personnel-related costs (including stock-based compensation), circuit design costs, purchases of materials and laboratory supplies, fabrication and packaging of experimental integrated circuit products, depreciation of research and development related capital equipment and overhead and are expensed as incurred. Stock-based Compensation Stock-based compensation arrangements include stock option grants and restricted stock unit (RSU) awards under the Company’s equity incentive plans, as well as shares issued under the Company’s Employee Stock Purchase Plan (ESPP), through which employees may purchase the Company’s common stock at a discount to the market price. The Company measures its stock option grants based on the estimated fair value of the options as of the grant date using the Black-Scholes option-pricing model. Stock-based compensation expense is recognized over the requisite service period using the straight-line method. The Company accounts for forfeitures as they occur. Expected volatility. The Company determines the expected stock price volatility based on the historical volatility of its common stock and the historical volatilities of a peer group. Industry peers consist of several public companies in the technology industry similar in size, stage of life cycle and financial leverage. If circumstances change such that the identified companies are no longer similar, the Company will revise its peer group to substitute more suitable companies in this calculation. Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield with a maturity equal to the expected term of the option in effect at the time of grant. Expected term. The expected term represents the period that the stock-based awards are expected to be outstanding. The Company used the simplified method to determine the expected term, which is calculated as the average of the time to vesting and the contractual life of the options. Dividend yield. The Company has never paid dividends on its common stock and is prohibited from paying dividends on its common stock. Therefore, the Company used an expected dividend yield of zero. Income Taxes The Company uses the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company must then assess the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The Company recognizes benefits of uncertain tax positions if it is more likely than not that such positions will be sustained upon examination based solely on their technical merits, as the largest amount of benefit that is more likely than not to be realized upon the ultimate settlement. The Company’s policy is to recognize interest and penalties related to the underpayment of income taxes as a component of income tax expense or benefit. 54 Table of Contents Net Income per Common Share Basic net income per common share is calculated by dividing the net income by the weighted-average number of shares of common stock outstanding for the period less shares subject to repurchase, without consideration of potentially dilutive securities. Diluted earnings per share is calculated using the treasury stock method by dividing net income by the total weighted average shares of common stock outstanding in addition to the potential impact of dilutive securities including restricted stock units, warrants, and options. In periods with a net loss, diluted net loss per common share is the same as basic net loss per common share since the effect of potentially dilutive securities is anti-dilutive. Recently Issued Pronouncements In June 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. As the Company is a smaller reporting company, ASU 2016-13 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2022, and requires a cumulative effect adjustment to the balance sheet as of the beginning of the first reporting period in which the guidance is effective. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements Financial Instruments-Credit Losses (Topic 326). ASU No. 2019-04 provides narrow-scope amendments to help apply ASU No. 2016-13, and is effective with the adoption of ASU No. 2016-13. The Company is evaluating the impact of the adoption of ASU 2016-13 and ASU No. 2019-04 on its financial statements. ​ Subsequent Events ​ The Company evaluated events after December 31, 2022, and through the date the financial statements were issued, and determined any events or transactions occurring during this period that would require recognition or disclosure are appropriately addressed in these financial statements. ​ 3.

Two of the patents were assigned to the customer in September 2021, and the remaining three patents were assigned to the customer in October 2021. Control is transferred when the patents are assigned to the customer. As a result, all $ 5.25 million of patent revenue was recognized during the year ended December 31, 2021, related to the patent sales. There were no patent sales for the year ended December 31, 2022. The Company licenses its intellectual property and is entitled to consideration based on the customer’s sales. The Company makes estimates in instances when the customer reports sales on a lagged basis and actual information is not available timely. The estimates are based on historical trends in the customer’s activity and current market conditions. In the year ended December 31, 2022, the Company recognized $ 0.3 million of royalty revenue related to activity occurring in the year ended December 31, 2021. In the year ended December 31, 2021, the Company recognized $ 0.8 million of royalty revenue related to activity occurring in the year ended December 31, 2020. This is a change in estimate and is based on actual information received from the customer. The amounts are reported in licensing, royalty, patent and other revenue in the statements of income and comprehensive income. The Company recognizes revenue in three geographic regions: Asia-Pacific (APAC); North America; and Europe, Middle East and Africa (EMEA). We recognize revenue by geography based on the region in which our products are sold, and not to where the end products in which they are assembled are shipped. Our revenue by region for the periods indicated was as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ 2022 2021 APAC ​ $ 35,631 ​ $ 32,327 North America ​ ​ 14,533 ​ ​ 15,813 EMEA ​ ​ 9,821 ​ ​ 7,006 Total revenue ​ $ 59,985 ​ $ 55,146 ​ ​ ​ 4.

The Company does not share in the rights to future revenues or royalties. The total arrangements are for $ 6.5 million in consideration. ​ The Company concluded these contractual arrangements represent one arrangement and evaluated its promises to the customer and whether the performance obligations granted under the arrangement were distinct. The licenses provided to the customer are not transferable, are of limited value without the promised development services, and the customer cannot benefit from the license agreements without the specific obligated services in the development subcontract, as there is strong interdependency between the licenses and the development subcontract. Accordingly, the Company determined the licenses were not distinct within the context of the contract and combined the license with other performance obligations. The total transaction price of $ 6.5 million was allocated to the single performance obligation. The Company recognizes revenue related to the performance obligations over time using the input method based on costs incurred to date relative to the total expected costs of the contract and began recognizing revenue in the second quarter of 2021 over the contract period. This method depicts performance under the contract and requires the Company to make estimates about the future costs expected to be incurred to perform under the contact, including labor and material costs. ​ As of December 31, 2022, the Company has billed $ 5.8 million for the performance under the RAD-Hard 1 contractual agreements. Under the input method of recognition, the Company has recognized $ 1.7 million in revenue for the year ending December 31, 2022, and $ 5.0 million in revenue since inception of the contractual agreements. As a result, the Company has recorded $ 0.8 million in deferred revenue as of December 31, 2022. The Company expects to 57 Table of Contents recognize the remaining $ 1.5 million of the transaction price as services are performed throughout the contractual period and performance is expected to be complete in the year ended December 31, 2024. ​ During the year ended December 31, 2022, the Company executed a contractual arrangement with a customer for the development of a strategic radiation hardened field programmable gate array product, consisting of a technology license to provide design and development services under the contractual agreement (RAD-Hard 2). The Company does not share in the rights to future revenues or royalties. The total arrangement is for $ 6.5 million in consideration and services are expected to be performed through the year ended December 31, 2024, subject to certain termination and extension provisions defined in the arrangement. The accounting for this contract follows the same revenue recognition as the RAD-Hard 1 contractual agreements. For the year ended December 31, 2022, the Company has billed $ 0.3 million for the performance under the RAD-Hard 2 contractual agreement. Under the input method of recognition, the Company has recognized $ 0.3 million in revenue for the year ending December 31, 2022. As a result, the Company does no t have a deferred revenue balance as of December 31, 2022 related to the RAD-Hard 2 contractual agreement. ​ 5. Commitments and Contingencies Leases Operating leases consist of fabrication, lab, and office space expiring at various dates through 2029.

Lease costs for the Company’s finance lease were immaterial for the years ended December 31, 2022 and 2021. 58 Table of Contents Legal Proceedings From time to time, the Company may become involved in legal proceedings arising from the ordinary course of its business. Management is currently not aware of any matters that it expects will have a material adverse effect on the financial position, results of operations or cash flows of the Company. Indemnifications In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to such agreements, the Company may indemnify, hold harmless and defend an indemnified party for losses suffered or incurred by the indemnified party. Some of the provisions will limit losses to those arising from third party actions. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential amount of future payments the Company could be required to make under these provisions is not determinable. The Company has never incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. The Company has also entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted by Delaware corporate law. The Company currently has directors’ and officers’ insurance. 6. Debt In May 2017, we executed the 2017 Credit Facility with SVB for a $ 12.0 million term loan, which we subsequently amended in January 2019 and June 2019. In August 2019, the 2019 Credit Facility amended and restated the 2017 Credit Facility, providing for a Line of Credit and the 2019 Term Loan with SVB to refinance in full the outstanding principal balance of $ 8.0 million under the 2017 Credit Facility. ​ In July 2020, we executed the first amendment to the 2019 Credit Facility with SVB. The amendment, among other things, extended the initial 12-month interest-only period for the term loan to a 16-month interest-only period and lowered the floor interest rate. The floor interest rates for 2019 Term Loan and the Line of Credit Facility were reduced from 4.75 % and 6.75 % to 3.75 % and 4.75 %, respectively. The amended Line of Credit allows for a maximum draw of $ 5.0 million, subject to a formula borrowing base, has a two-year term and bears interest at a floating rate equal to the WSJ prime rate plus 1.5 %, per annum, subject to a floor of 4.75 %. As of December 31, 2022, the interest rate was 9.00 %. The Line of Credit required a commitment fee of 1.6 % of the maximum availability of the Line of Credit, which was paid in August 2019 upon closing, and was accounted for as a debt discount. The Line of Credit also provides for a termination fee equal to 1 % of the maximum availability under the Line of Credit, which is due in case of a termination of the Line of Credit prior to the scheduled maturity date, and an unused facility fee equal to 0.125 % per annum of the average unused portion of the Line of Credit, which is expensed as incurred. Currently, $ 4.0 million remains available under the Line of Credit, subject to borrowing base availability. As of December 31, 2022, the effective interest rate under the Line of Credit was 9.36 % and the outstanding balance was $ 1.0 million. The Line of Credit was set to mature on August 5, 2022. The third amendment entered into on July 22, 2022, extended the maturity date of the Line of Credit to August 5, 2023. ​ The amended 2019 Term Loan provides for a $ 6.0 million term loan. The amended 2019 Term Loan has a term of 46 months , and a 16-month interest-only period followed by 30 months of equal principal payments of $ 200,000 per month, plus accrued interest. The 2019 Term Loan bears interest at a floating rate equal to the WSJ prime rate minus 0.75 %, subject to a floor of 3.75 %. As of December 31, 2022, the interest rate was 6.75 %. A final payment of 7 % of the original principal amount of the 2019 Term Loan must be made when the 2019 Term Loan is prepaid or repaid, whether at maturity or as a result of a prepayment or acceleration or otherwise. The additional payment, which is accounted for as a debt discount, is being accreted using the effective interest method. The 2019 Term Loan has a prepayment fee equal to 2 % of the total commitment, which is due only if the 2019 Term Loan is prepaid prior to the scheduled maturity date for any reason. As of December 31, 2022, the effective interest rate under the 2019 Term Loan was 6.94 % and the outstanding balance was $ 1.6 million. The 2019 Term Loan matures on June 1, 2023. Collateral for the 2019 Credit Facility includes all of our assets except for intellectual property. We are required to comply with certain covenants under the 2019 Credit Facility, including requirements to maintain a minimum cash balance and availability under the Line of Credit, and restrictions on certain actions without the consent of the lender, 59 Table of Contents such as limitations on our ability to engage in mergers or acquisitions, sell assets, incur indebtedness, or grant liens or negative pledges on our assets, make loans or make other investments.

Stock-Based Compensation 2016 Employee Incentive Plan The Company’s board of directors adopted the 2016 Equity Incentive Plan (the 2016 Plan) on April 25, 2016, which was subsequently approved on September 20, 2016 by the Company’s stockholders. The 2016 Plan became effective on October 7, 2016, the date the Company’s S-8 registration statement relating to the 2016 Plan was declared effective by the SEC. The Company’s 2016 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based stock awards, and other forms of equity compensation to employees, directors, and consultants. In addition, the Company’s 2016 Plan provides for the grant of performance cash awards to employees, directors, and consultants. The maximum number of shares of common stock that may be issued under the Company’s 2016 Plan was initially 500,000 subject to an automatic increase on January 1 of each year, beginning on January 1, 2017, and continuing through and including January 1, 2026, by 3 % of the total number of shares of capital stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by the Company’s board of directors. On May 20, 2021, the Company’s stockholders approved an amendment to the 2016 Plan to increase the total number of authorized shares of common stock available for grant thereunder by an additional 550,000 shares. At December 31, 2022, of the 3,261,836 shares of common stock reserved and available for grant under the 2016 Plan, 689,472 shares of common stock remain available for grant under the 2016 Plan. 2008 Employee Incentive Plan The 2008 Equity Incentive Plan (the 2008 Plan) provided for the issuance of incentive stock options (ISO), nonqualified stock options, and other stock compensation awards. Due to the adoption of the 2016 Plan, no further grants will be made under the Company’s 2008 Plan. However, any outstanding stock awards granted under the 2008 Plan will remain outstanding, subject to the terms of the Company’s 2008 Plan and the applicable stock award agreements, until such outstanding stock awards that are stock options are exercised or until they terminate or expire by their terms, or until such stock awards are fully settled, terminated, or forfeited.

Joint Development Agreement Since October 17, 2014, the Company has participated in a joint development agreement (JDA) with GLOBALFOUNDRIES Inc. (GF), a semiconductor foundry, for the joint development of Spin-transfer Torque MRAM (STT-MRAM) technology to produce a family of discrete and embedded MRAM technologies. The term of the agreement is until the completion, termination, or expiration of the last statement of work entered into pursuant to the joint development agreement. The agreement was extended on December 31, 2019 to include a new phase of support for 12nm MRAM development. Under the current JDA extension terms, each party licenses its relevant intellectual property to the other party. For certain jointly developed works, the parties have agreed to follow an invention allocation procedure to determine ownership. In addition, GF possesses the exclusive right to manufacture the Company’s discrete and embedded STT-MRAM devices developed pursuant to the agreement until the earlier of three years after the qualification of the MRAM device for a particular technology node or four years after the completion of the relevant statement of work under which the device was developed. For the same exclusivity period associated with the relevant device, GF agreed not to license intellectual property developed in connection with the JDA to named competitors of the Company. Generally, unless otherwise specified in the agreement or a statement of work, the Company and GF share project costs, which do not include personnel or production qualification costs, under the JDA. If GF manufactures, sells, or transfers to customers wafers containing production quantified STT-MRAM devices that utilize certain design information, GF will be required to pay the Company a royalty. 63 Table of Contents 11.

Management must use judgment in assessing the potential need for a valuation allowance, which requires an evaluation of both negative and positive evidence. The weight given to the potential effect of negative and positive evidence should be commensurate with the extent to which it can be objectively verified. In determining the need for and amount of the valuation allowance, if any, the Company assesses the likelihood that it will be able to recover its deferred tax assets using historical levels of income, estimates of future income and tax planning strategies. As a result of historical cumulative losses, the Company determined that, based on all available evidence, there was substantial uncertainty as to whether it will recover recorded net deferred taxes in future periods. Accordingly, the Company recorded a valuation allowance against all of its net deferred tax assets as of December 31, 2022 and 2021. The net valuation allowance decreased by $ 1.7 million in 2022. As of December 31, 2022, the Company has federal net operating loss carryforwards of approximately $ 119.9 million, of which $ 79.1 million will expire in 2028 through 2037 if not utilized, and $ 40.8 million that will carryover indefinitely. In addition, the Company has state net operating loss carryforwards of approximately $ 50.3 million, of which $ 47.5 million will expire in 2028 through 2041 if not utilized, and $ 2.8 million that will carryover indefinitely. The Tax Reform Act of 1986 (the Act) provides for a limitation on the annual use of net operating loss carryforwards following certain ownership changes (as defined by the Act and codified under Section 382 of the U.S. Internal Revenue Code of 1986, as amended (the Code)) that could limit the Company’s ability to utilize these carryforwards. Further, a portion of the carryforwards may expire before utilized to reduce future income tax liabilities as a result of the annual limitation. The Company experienced an ownership change in October 2016 and as a result, $ 43.8 million ($ 9.2 million tax effected) of the federal NOLs are expected to expire unutilized due to limitation under 65 Table of Contents Section 382 of the Code. The NOLs expected to expire unutilized are included in the NOL carryforward amounts disclosed, subject to a valuation allowance. The Company files income tax returns in the U.S. federal and various state jurisdictions. The Company is generally subject to U.S. federal and state income tax examination for all tax years beginning in 2008, due to the net operating losses that are carried forward. ​ A summary of changes in the Company’s gross unrecognized tax benefits for the years ended December 31, 2022 and 2021 was as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ ​ 2022 2021 Unrecognized tax expense, beginning of the year ​ $ 105 ​ $ 104 Decrease related to prior year tax positions ​ ​ ( 16 ) ​ ​ ( 12 ) Increase related to current year tax positions ​ ​ 16 ​ ​ 13 Unrecognized tax expense, end of year ​ $ 105 ​ $ 105 ​ The total balance of unrecognized tax benefits as of December 31, 2022 would impact the effective tax rate, if recognized. ​ The Company's policy is to recognize interest and penalties accrued on any unrecognized tax benefit as a component of income tax expense. The Company has accrued penalties and interest of $ 155,000 , as of both December 31, 2022 and 2021. ​ 13.
