Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures As required by Rule 13a-15 under the Exchange Act, we have carried out an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Report. This evaluation was carried out under the supervision and with the participation of our management, including our principal executive officer and principal financial officer. Based on their evaluation as of December 31, 2022, the end of the period covered by this Report, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective at a reasonable assurance level to ensure that the information required to be disclosed in reports filed or submitted under the Exchange Act, including this Report, was recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and was accumulated and communicated to management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Management’s Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting (as defined in Rule 13a-15(f) ender the Exchange Act) includes those policies and procedures that: (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements. 16 Table of Contents Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Management (with the participation of the CEO and CFO) conducted an evaluation of the effectiveness of Company’s internal control over financial reporting based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that Company’s internal control over financial reporting was effective as of December 31, 2022. This Report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm because as a smaller reporting company we are not subject to Section 404(b) of the Sarbanes-Oxley Act of 2002. Changes in Internal Control over Financial Reporting There were no changes in our internal controls over financial reporting during the three months ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect our internal controls over financial reporting.

The Retention Plan incentivizes certain management level employees to remain intact through and shortly following a potential “Change of Control” (as defined in the Retention Plan). The Retention Plan provides that certain managers are eligible to receive a lump sum cash amount under the Retention Plan, subject to applicable income and employment tax withholding, with such amount to be determined by the Committee in its sole discretion (the “Retention Bonus Amount”). Each Manager’s Retention Bonus Amount is payable (if at all) on the earlier of the six-month anniversary of the date of a Change of Control or at the time of such Manager’s involuntary termination other than for “Cause” (as defined in the Retention Plan) or termination for “Good Reason” (as defined in the Retention Plan). The Retention Plan will terminate upon the earlier of June 30, 2023 if a Change of Control has not occurred by such date or upon the payment of all Retention Bonus Amounts. Pursuant to such authority and the Retention Plan, on September 1, 2022, the Committee also approved aggregate Retention Bonus Amounts of $1,250,000. Among the managers deemed by the Committee to be eligible for such payments, the Committee approved Retention Bonus Amounts for the following Company named executive officers: Brett Moyer, Chief Executive Officer, $300,000; George Oliva, Chief Financial Officer, $200,000; and Gary Williams, Chief Accounting Officer and Vice President of Finance, $75,000. Equity Incentive Plans 2018 Long-Term Stock Incentive Plan of the Company (the “LTIP”) On January 30, 2018, the Board approved the establishment of the LTIP. The LTIP is intended to enable the Company to continue to attract able directors, employees, and consultants and to provide a means whereby those individuals upon whom the responsibilities rest for successful administration and management of the Company, and whose present and potential contributions are of importance, can acquire and maintain Common Stock ownership, thereby strengthening their concern for the Company’s welfare. The aggregate maximum number of shares of Common Stock (including shares underlying options) that may be issued under the LTIP pursuant to awards of Restricted Shares or Options will be limited to 15% of the outstanding shares of Common Stock, which calculation shall be made on the first trading day of each new fiscal year; provided that, in any year no more than 8% of the Common Stock or derivative securitization with Common Stock underlying 8% of the Common Stock may be issued in any fiscal year. For fiscal year 2022, up to 108,373 shares of Common Stock were available for participants under the LTIP. For fiscal year 2021, up to 23,746 shares of Common Stock were initially available for participants under the LTIP. The number of shares of Common Stock that are the subject of awards under the LTIP which are forfeited or terminated, are settled in cash in lieu of shares of Common Stock or in a manner such that all or some of the shares covered by an award are not issued to a participant or are exchanged for awards that do not involve shares will again 28 Table of Contents immediately become available to be issued pursuant to awards granted under the LTIP. If shares of Common Stock are withheld from payment of an award to satisfy tax obligations with respect to the award, those shares of Common Stock will be treated as shares that have been issued under the LTIP and will not again be available for issuance under the LTIP. The January 2018 Restricted Stock Grant and the LTIP were approved by a majority of the Company’s stockholders on January 31, 2018. At a special meeting of our stockholders held on January 24, 2023, our stockholders approved certain amendments to the LTIP to: (i) increase the annual share limit of Common Stock that may be issued in any single fiscal year only for the 2023 fiscal year under the LTIP from 8% of the shares of Common Stock outstanding to 15% of the shares of Common Stock outstanding (which amount equates to the maximum amount that may be issued in the aggregate under the LTIP); and (ii) permit immediately quarterly calculations based on the number of shares of Common Stock outstanding as of the first trading day of each fiscal quarter, rather than solely as of the first trading day of the fiscal year. 2020 Stock Incentive Plan (the “2020 Plan”) On July 27, 2020, the Board approved the establishment of the 2020 Plan and the reservation of an aggregate of 650,000 shares of Common Stock authorized for issuance under the 2020 Plan, subject to stockholder approval, which was obtained on October 20, 2020. The 2020 Plan authorizes the grant of equity-based compensation to the Company’s senior managers, employees, directors, consultants, professionals and service providers in the form of stock options, restricted stock and RSUs. All options granted under the 2020 Plan will be considered non-qualified stock options. The purpose of the 2020 Plan is to attract and retain senior managers, employees, directors, consultants, professionals and service providers who provide services to the Company, provided that such services are bona fide services that are not of a capital-raising nature during this period of unprecedented uncertainty and volatility in the COVID-19 environment and its impact on the value of the Company’s equity and grants. As of December 31, 2022, no options or restricted stock awards have been granted under the 2020 Plan while an aggregate of 121 RSUs have been issued under the 2020 Plan of which 2,161 remained unvested at December 31, 2022. Technical Team Retention Plan of 2022 (the “2022 Plan”) On June 21, 2022, the Board of Directors adopted the Company’s Technical Team Retention Plan of 2022 (the “2022 Plan”) and the reservation of an aggregate of 5,000 shares of the Company’s common stock authorized for issuance under the 2022 Plan, subject to stockholder approval. The 2022 Plan authorizes the grant of equity-based compensation, to the Company’s key managers, employees, consultants who provide technical and engineering and related services to the Company, in the form of restricted stock and restricted stock units. On August 19, 2022, the Company held the 2022 Annual Meeting of Stockholders and approved the adoption of the 2022 Plan and the reservation of an aggregate of 5,000 shares of the Company’s common stock. On September 19, 2022, the Company granted, an aggregate of 3,700 restricted stock units to managers, employees, consultants. Each restricted stock unit represents the right to receive one share of the Company’s common stock under the 2022 Plan. As of December 31, 2022, no options or restricted stock awards have been granted under the 2022 Plan while an aggregate of 3,700 RSUs have been issued under the 2022 Plan of which 3,700 remained unvested at December 31, 2022. ​ 29 Table of Contents DIRECTOR COMPENSATION The table below sets forth the compensation paid to our directors during the fiscal year ended December 31, 2022.

Related Person Transaction Policy Our Audit Committee considers and approves or disapproves any related person transaction as required by Nasdaq regulations. The Company’s written policies and procedures on related party transactions cover any transaction, arrangement or relationship or series of similar transactions, arrangements or relationships (including any indebtedness or guarantee of indebtedness) in which: (i) the Company (or any subsidiary) is a participant; (ii) any related party has or will have a direct or indirect interest; and (iii) the aggregate amount involved (including any interest payable with respect to indebtedness) will or may be expected to exceed $120,000, except that there is no $120,000 threshold for members of the Audit Committee. A related party is any: (i) person who is or was (since the beginning of the two fiscal years preceding the last fiscal year, even if they do not presently serve in that role) an executive officer, director or nominee for election as a director; (ii) greater than five percent (5%) beneficial owner of the Company’s common stock or any other class of the Company’s voting equity securities; or (iii) immediate family member of any of the foregoing. An immediate family member includes a person’s spouse, parents, stepparents, children, stepchildren, siblings, mothers- and fathers-in-law, sons- and daughters-in-law, and brothers- and sisters-in-law and any person (other than a tenant or employee) sharing the same household as such person. In determining whether to approve or ratify a related party transaction, the Audit Committee, or disinterested directors, as applicable, will take into account, among other factors it deems appropriate: (i) whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances; (ii) the nature and extent of the related party’s interest in the transaction; (iii) the material terms of the transactions; (iv) the importance of the transaction both to the Company and to the related party; (v) in the case of a transaction involving an executive officer or director, whether the transaction would interfere with the performance of such person’s duties to the Company; and (vi) in the case of a transaction involving a non-employee director or a nominee for election as a non-employee director (or their immediate family member), whether the transaction would disqualify the director or nominee from being deemed an “independent” director, as defined by Nasdaq, and whether the transaction would disqualify the individual from serving on the Audit Committee or the Compensation Committee or other committees of the Board under applicable Nasdaq and other regulatory requirements. The Audit Committee only approves those related party transactions that are on terms comparable to, or more beneficial to us than, those that could be obtained in arm’s length dealings with an unrelated third party. 35 Table of Contents Director Independence See “ Corporate Governance—Director Independence .” Item 14.

Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated balance sheets of WiSA Technologies, Inc. (a Delaware corporation) and its subsidiaries (the “Company”) as of December 31, 2022 and 2021, the related consolidated statements of operations, convertible preferred stock and stockholders’ equity(deficit), 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 “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America. Going Concern Uncertainty The accompanying consolidated financial statements have been prepared assuming that WiSA Technologies, Inc. and its subsidiaries will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company’s recurring losses from operations, a net capital deficiency, available cash and cash used in operations raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. ​ We have served as the Company’s auditor since 2016. ​ /s/ BPM LLP ​ San Jose, California ​ March 16, 2023 ​ ​ ​ ​ ​ F-1 Table of Contents WISA TECHNOLOGIES, INC.

Business and Summary of Significant Accounting Policies WiSA Technologies, Inc formerly known as Summit Wireless Technologies, Inc. (together with its subsidiaries also referred to herein as “we”, “us”, “our”, or the “Company”) was originally formed as a limited liability company in Delaware on July 23, 2010. Our business is to deliver the best-in-class immersive wireless sound technology for intelligent devices and next generation home entertainment systems through the sale of module components to audio companies as well as audio products to resellers and consumers. NASDAQ Notifications On June 23, 2022, the Company received a written notification (the “Notice”) from the Listing Qualifications Department of the Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that it was not in compliance with the minimum bid price requirement for continued listing on the Nasdaq Capital Market, as set forth under Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”), because the closing bid price of the Company’s common stock was below $ 1.00 per share for the previous thirty (30) consecutive business days. Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company was granted 180 calendar days from the date of the Notice, or until December 20, 2022 (the “Compliance Period”), to regain compliance with the Minimum Bid Price Requirement. The Company’s Common Stock failed to regain compliance with the Minimum Bid Price Requirement as of December 20, 2022. On December 19, 2022, the Company requested an extension of an additional 180 days in which to regain compliance with the Minimum Bid Price Requirement. On December 21, 2022, the Company received notice (the “Second Notice”) from Nasdaq indicating that, while the Company has not regained compliance with the Minimum Bid Price Requirement, Staff has determined that the Company is eligible for an additional 180-day period, or until June 20, 2023 (the “Second Compliance Period”), to regain compliance. On January 18, 2023, the Company received notice (the “January 18 Letter”) from the Nasdaq that it had determined that as of January 18, 2023, the Company’s Common Stock had a closing bid price of $ 0.10 or less for ten consecutive trading days triggering application of Listing Rule 5810(c)(3)(A)(iii) (the “Low Priced Stocks Rule”). On February 13, 2023, the Company received notice (the “February 13 Letter”) from Nasdaq that it had determined that the Company had cured its bid price deficiency and now complies with the Minimum Bid Price Requirement, as the closing bid price of the Company’s common stock was at least $ 1.00 per share for at least a minimum of 10 consecutive business days. The Company also believes that it is also in compliance with the Low Priced Stocks Rule. On December 21, 2022, the Company received a letter from Nasdaq notifying the Company that it had determined that the Company did not comply with Listing Rule 5635(d) because the Company’s December 2022 public offering did not meet Nasdaq’s definition of a public offering under Listing Rule IM-5635-3. Nasdaq’s determination was based on the significant discount to the “Minimum Price,” as defined in Nasdaq rules. The Company had requested a hearing before a Nasdaq panel to appeal the January 18 Letter and to address all outstanding matters, including compliance with the Minimum Bid Price Requirement, the Low Priced Stocks Rule and Nasdaq Listing Rule 5635(d), which hearing is scheduled for March 9, 2023. As a result of the February 13 Letter, the Company only need to address its compliance with the Nasdaq Listing Rule 5635(d) in the hearing. While the appeal process is pending, the suspension of trading of the Company’s Common Stock will be stayed and our Common Stock will continue to trade on Nasdaq until the hearing process concludes and the Panel issues a written decision.

Business and Summary of Significant Accounting Policies, continued Strategic Advisor During the third quarter of 2022, the Company retained a strategic advisor to explore strategic opportunities specifically involving the Company’s intellectual property. Potential strategic opportunities that may be explored or evaluated as part of this process include the potential for capital raising transactions, an acquisition, sale of assets, including substantially all of the Company’s assets, merger, business combination, partnership, joint venture, licensing and/or another strategic alternative. Despite the Company’s efforts to identify and evaluate potential strategic transactions, the process may not result in any definitive offer to consummate a strategic transaction, or, if we receive such a definitive offer, the terms may not be as favorable as anticipated or may not result in the execution or approval of a definitive agreement. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include all adjustments necessary for the fair presentation of the Company’s financial position, results of operations and cash flows for the periods presented. The consolidated financial statements reflect the accounts of WISA Technologies, Inc. and its wholly-owned subsidiaries, WISA Technologies Korea, LTD, a Korean limited company, which was established in September 2022, and WiSA, LLC, a Delaware limited liability company. All intercompany balances and transactions are eliminated. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Reclassification Certain reclassifications have been made to prior periods’ consolidated financial statements to conform to the current period presentation. These reclassifications did not result in any change in previously reported net loss, total assets or stockholders’ equity. Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. Cash and cash equivalents are deposited in demand and money market accounts at one financial institution. At times, such deposits may be in excess of insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. The Company’s accounts receivable are derived from revenue earned from customers located throughout the world. The Company performs credit evaluations of its customers’ financial condition and may, in certain circumstances, require full or partial payment in advance of shipping. As of December 31, 2022 and December 31, 2021, there was no allowance for doubtful accounts. As of December 31, 2022, the Company had two customers accounting for 62 % and 12 % of accounts receivable. As of December 31, 2021, the Company had two customers accounting for 35 % and 27 % of accounts receivable. The Company had four customers accounting for 19 %, 18 %, 11 % and 10 % of its net revenue for the year ended December 31, 2022. The Company had three customers accounting for 27 %, 17 % and 14 % of its net revenue for the year ended December 31, 2021. F-7 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 1. Business and Summary of Significant Accounting Policies, continued The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, rapid technological change, continued acceptance of the Company’s products, competition from substitute products and larger companies, protection of proprietary technology, strategic relationships and dependence on key individuals. The Company relies on sole-source suppliers to manufacture some of the components used in its product. The Company’s manufacturers and suppliers may encounter problems during manufacturing due to a variety of reasons, any of which could delay or impede their ability to meet demand. The Company is heavily dependent on a single contractor in China for assembly and testing of its products, a single contractor in Japan for the production of its transmit semiconductor chip and a single contractor in China for the production of its receive semiconductor chip. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at the invoice amount and are generally not interest bearing. The Company reviews its trade receivables aging to identify specific customers with known disputes or collection issues. The Company exercises judgment when determining the adequacy of these reserves as it evaluates historical bad debt trends and changes to customers’ financial conditions. Uncollectible receivables are recorded as bad debt expense when all efforts to collect have been exhausted and recoveries are recognized when they are received. As of December 31, 2022 and 2021, there was no allowance for doubtful accounts. Fair Value of Financial Instruments Carrying amounts of certain of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued liabilities approximate fair value due to their relatively short maturities. The carrying value of the Company’s borrowings and capital lease liabilities approximates fair value based upon borrowing rates currently available to the Company for loans and capital leases with similar terms. The Company’s Warrant liability and Derivative liability are the only financial instruments that are adjusted to fair value on a recurring basis. Inventories Inventories, principally purchased components, are stated at the lower of cost or net realizable value. Cost is determined using an average cost, which approximates actual cost on a first-in, first-out basis. Inventory in excess of salable amounts and inventory which is considered obsolete based upon changes in existing technology is written off. 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 the new cost basis. Deferred Offering Costs Deferred offering costs, consisting of legal, accounting and filing fees relating to public offerings, are capitalized. The deferred offering costs will be offset against public offering proceeds upon the effectiveness of an offering. In the event that an offering is terminated, deferred offering costs will be expensed. As of December 31, 2022 and 2021, the Company had capitalized $ 206,000 and $ 83,000 , respectively, of deferred offering costs in prepaid expenses and other current assets on the consolidated balance sheet. F-8 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 1. Business and Summary of Significant Accounting Policies, continued Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation of property and equipment is computed using the straight-line method over their estimated useful lives of two to five years . Leasehold improvements and assets acquired under capital lease are amortized on a straight-line basis over the shorter of the useful life or term of the lease. Upon retirement or sale, the cost and related accumulated depreciation are removed from the balance sheet and the resulting gain or loss is reflected in operations. Maintenance and repairs are charged to operations as incurred. Intangible Assets Intangible assets consisted of trademarks and are presented at cost, net of accumulated amortization. The intangible assets are amortized using the straight-line method over their estimated useful lives of three years , which approximates the economic benefit. If our underlying assumptions regarding the estimated useful life of an intangible asset change, then the amortization period, amortization expense and the carrying value for such asset would be adjusted accordingly. Impairment of Long-Lived Assets The Company evaluates its long-lived assets for indicators of possible impairment by comparison of the carrying amounts to future net undiscounted cash flows expected to be generated by such assets when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Should an impairment exist, the impairment loss would be measured based on the excess carrying value of the asset over the asset’s fair value or discounted estimates of future cash flows. The Company has not identified any such impairment losses to date. Convertible Financial Instruments The Company bifurcates conversion options and warrants from their host instruments and accounts for them as freestanding derivative financial instruments if certain criteria are met. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument. An exception to this rule is when the host instrument is deemed to be conventional, as that term is described under applicable U.S. GAAP. When the Company has determined that the embedded conversion options and warrants should be bifurcated from their host instruments, discounts are recorded for the intrinsic value of conversion options embedded in the instruments based upon the differences between the fair value of the underlying common stock at the commitment date of the transaction and the effective conversion price embedded in the instrument. Debt discounts under these arrangements are amortized to interest expense using the interest method over the earlier of the term of the related debt or their earliest date of redemption. F-9 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 1. Business and Summary of Significant Accounting Policies, continued Warrants for Common Shares and Derivative Financial Instruments Warrants for our shares of common stock and other derivative financial instruments are classified as equity if the contracts (1) require physical settlement or net-share settlement or (2) give the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). Contracts which (1) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the control of the Company), (2) give the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement), or (3) that contain reset provisions that do not qualify for the scope exception are classified as equity or liabilities. The Company assesses classification of its warrants for shares of common stock and other derivatives at each reporting date to determine whether a change in classification between equity and liabilities is required. In an equity-classified freestanding financial instrument, as of the date that a down round feature is triggered, the Company measures the fair value of the instrument without the down round feature (that is, before the strike price is reduced) and the fair value of the financial instrument with a strike price that reflects the adjustment from the down round. The incremental difference in the fair value is recorded a deemed dividend. As the Company has an accumulated deficit, the deemed dividend is recorded as a reduction of additional paid-in capital in the consolidated balance sheet. The Company increases the net loss available to common stockholders by the amount of the deemed dividend. Product Warranty The Company's products are generally subject to a one year warranty, which provides for the repair, rework, or replacement of products (at the Company's option) that fail to perform within the stated specification. The Company has assessed its historical claims and, to date, product warranty claims have not been significant. The Company will continue to assess if there should be a warranty accrual going forward. Revenue Recognition The Company generates revenue primarily from two product categories which include the sale of Consumer Audio Products as well as the sale of Components The Company applies the following five steps: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied. The Company considers customer purchase orders to be the contracts with a customer. Revenues, net of expected discounts, are recognized when the performance obligations of the contract with the customer are satisfied and when control of the promised goods are transferred to the customer, typically when products, which have been determined to be the only distinct performance obligations, are shipped to the customer. Expected costs of assurance warranties and claims are recognized as expense. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by us from a customer and deposited with the relevant government authority, are excluded from revenue. Our revenue arrangements do not contain significant financing components. Sales to certain distributors are made under arrangements which provide the distributors with price adjustments, price protection, stock rotation and other allowances under certain circumstances. The Company does not provide its customers with a contractual right of return. However, the Company accepts limited returns on a case-by-case basis. These returns, adjustments and other allowances are accounted for as variable consideration. We estimate these amounts based on the expected amount to be provided to customers and reduce revenue recognized. We believe that there will not be significant changes to our estimates of variable consideration. If a customer pays consideration, or the Company has a right to an amount of consideration that is unconditional before we transfer a good or service to the customer, those amounts are classified as contract liabilities which are included in other current liabilities when the payment is made or it is due, whichever is earlier.

Amounts collected prior to the fulfillment of the performance obligation are considered contract liabilities and classified as customer advances within accrued liabilities on the consolidated balance sheets. Contract assets are recorded when we have a conditional right to consideration for our completed performance under the contracts. Accounts receivables are recorded when the right to this consideration becomes unconditional. We do not have any material contract assets as of December 31, 2022 and 2021. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ December 31, (in thousands) 2022 2021 Contract liabilities ​ $ 44 ​ $ — ​ Revenue by Geographic Area In general, revenue disaggregated by geography (See Note 10) is aligned according to the nature and economic characteristics of our business and provides meaningful disaggregation of our results of operations. Since we operate in one segment, all financial segment and product line information can be found in the consolidated financial statements. Practical Expedients and Exemptions As part of our adoption of Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, we elected to use the following practical expedients: (i) not to adjust the promised amount of consideration for the effects of a significant financing component when we expect, at contract inception, that the period between our transfer of a promised product or service to a customer and when the customer pays for that product or service will be one year or less; (ii) to expense costs as incurred for costs to obtain a contract when the amortization period would have been one year or less; (iii) not to assess whether promised goods or services are performance obligations if they are immaterial in the context of the contract with the customer. In addition, we do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. ​ F-11 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 1. Business and Summary of Significant Accounting Policies, continued Stock-Based Compensation The Company measures and recognizes the compensation expense for restricted stock units and restricted stock awards granted to employees and directors based on the fair value of the award on the grant date. Restricted stock units give an employee an interest in Company stock but they have no tangible value until vesting is complete. Restricted stock units and restricted stock awards are equity classified and measured at the fair market value of the underlying stock at the grant date and recognized as expense over the related service or performance period. The Company elected to account for forfeitures as they occur. The fair value of stock awards is based on the quoted price of our common stock on the grant date. Compensation cost for restricted stock units and restricted stock awards is recognized using the straight-line method over the requisite service period. Research and Development Research and development costs are charged to operations as incurred and includes salaries, consulting expenses and an allocation of facility costs. Advertising Costs Advertising costs are charged to sales and marketing expenses as incurred. Advertising costs for the years ended December 31, 2022 and 2021 are $ 1,440,000 and $ 688,000 , respectively. Comprehensive Loss Comprehensive loss represents the changes in equity of an enterprise, other than those resulting from stockholder transactions. Accordingly, comprehensive loss may include certain changes in equity that are excluded from net loss. For the years ended December 31, 2022 and 2021, the Company’s comprehensive loss is the same as its net loss. Foreign Currency The financial position and results of operations of the Company’s foreign operations are measured using currencies other than the U.S. dollar as their functional currencies. Accordingly, for these operations all assets and liabilities are translated into U.S. dollars at the current exchange rates as of the respective balance sheet date. Expense items are translated using the weighted average exchange rates prevailing during the period. Cumulative gains and losses from the translation of these operations’ financial statements are reported as a separate component of stockholders’ equity, while foreign currency transaction gains or losses, resulting from re-measuring local currency to the U.S. dollar are recorded in the consolidated statements of operations in other expense, net and were not material for the years ended December 31, 2022 and 2021. Reverse Stock Split On January 26, 2023 the Company announced that its Board of Directors had approved a 1-for-100 reverse split (the "Reverse Stock Split") of its common stock that became effective that date. The common stock began trading on a split-adjusted basis on January 27, 2023 under the new CUSIP number 86633R302. All common stock share numbers, warrants to purchase common stock, prices and exercise prices have been retroactively adjusted to reflect the Reverse Stock Split. The par value of the common stock was not adjusted for the Reverse Stock Split. Net Loss per Common Share Basic and diluted net loss per common share is presented in conformity with the two-class method required for participating securities. The Company considers all series of convertible preferred stock to be participating securities. Under the two-class method, the net loss attributable to common stockholders is not allocated to the convertible preferred stock as the holders of the convertible preferred stock do not have a contractual obligation to share in the losses of the Company. Under the two-class method, net income would be attributed to common stockholders and participating securities based on their participation rights. ​ F-12 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 1. Business and Summary of Significant Accounting Policies, continued Basic net loss per common share 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 common share is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares and potentially dilutive common share equivalents outstanding for the period determined using the treasury-stock and if-converted methods. For purposes of the diluted net loss per common share calculation, Series A 8% Senior Convertible Preferred Stock, (“Series A Preferred Stock”), warrants exercisable for common stock, restricted stock units and shares issuable upon the conversion of convertible notes payable are considered to be potentially dilutive securities. For the year ended December 31, 2022, warrants to purchase 1,253,115 shares of common stock, 14,107 shares of restricted stock, 2,778 shares of restricted stock issued under an inducement grant and 5,861 shares underlying restricted stock units have been excluded from the calculation of net loss per common share because the inclusion would be antidilutive. Income Taxes Deferred taxes are provided on the liability method whereby deferred tax assets are recognized for deductible temporary differences, and operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is “more-likely-than-not” that some portion or all of the deferred tax assets will not be realized. The Company has recognized valuation allowances against its deferred tax assets as of December 31, 2022 and 2021. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. The Company uses a comprehensive model for recognizing, measuring, presenting, and disclosing in the consolidated financial statements tax positions taken or expected to be taken on a tax return. A tax position is recognized as a benefit only if it is “more-likely-than-not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50 % likely of being realized on examination. For tax positions not meeting the “more-likely-than-not” test, no tax benefit is recorded. The Company recognizes interest accrued and penalties related to unrecognized tax benefits in tax expense. During the years ended December 31, 2022 and 2021, the Company recognized no interest and penalties. Recently Adopted Accounting Pronouncements Adoption of Accounting Standards Codification (“ASC”) 842 The Company adopted Financial Accounting Standards Board’s (“FASB”) Accounting Standards Update (“ASU”) No. 2016-02, Leases (“Topic 842”), as of January 1, 2022, using the modified retrospective approach. The modified retrospective approach provides a method for recording existing leases at the beginning of the period of adoption. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification and the Company elected the hindsight practical expedient to determine the lease term for existing leases. Adoption of the new standard resulted in the recording of operating lease right-of-use assets of $ 212,000 and lease liabilities of $ 327,000 , as of January 1, 2022. In addition, the new standard resulted in the recording of an additional $ 90,000 of property and equipment and the reversal of $ 58,000 of deferred rent and lease incentive and an increase in shareholders’ equity of $ 33,000 as required under the new standard. The standard did not have an impact on our consolidated results of operations or cash flows. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. ​ F-13 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 1.

This ASU simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument and more convertible preferred stock as a single equity instrument with no separate accounting for embedded conversion features. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for the exception. The ASU also simplifies the diluted earnings per share (EPS) calculation in certain areas. As an emerging growth company, the Company is allowed to adopt the accounting pronouncement at the same time as non-public business entities. As a result, the Company will adopt the update for its fiscal year beginning after December 15, 2023. The Company is evaluating the impact of this standard on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, as amended, which requires the early recognition of credit losses on financing receivables and other financial assets in scope. ASU 2016-13 requires the use of a transition model that will result in the earlier recognition of allowances for losses. The new standard is effective for fiscal years beginning after December 15, 2022. Management is currently evaluating the new standard and its possible impact on the Company’s consolidated financial statements. We have reviewed other recent accounting pronouncements and concluded they are either not applicable to the business, or no material effect is expected on the consolidated financial statements as a result of future adoption. ​ ​ F-14 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 2. Going Concern The consolidated financial statements of the Company have been prepared on a going concern basis, which contemplates the realization of assets and the discharge of liabilities in the normal course of business. The Company has incurred net operating losses each year since inception. As of December 31, 2022, the Company had cash and cash equivalents of $ 2.9 million and reported net cash used in operations of $ 17.5 million during the year ended December 31, 2022. The Company expects operating losses to continue in the foreseeable future because of additional costs and expenses related to research and development activities, plans to expand its product portfolio, and increase its market share. The Company’s ability to transition to attaining profitable operations is dependent upon achieving a level of revenues adequate to support its cost structure. ​ Based on current operating levels, the Company will need to raise additional funds in the next 12 months by selling additional equity or incurring debt. To date, the Company has funded its operations primarily through sales of its securities in public markets, proceeds from the exercise of warrants to purchase common stock and the sale of convertible notes. Additionally, future capital requirements will depend on many factors, including the rate of revenue growth, the selling price of the Company’s products, the expansion of sales and marketing activities, the timing and extent of spending on research and development efforts and the continuing market acceptance of the Company’s products. These factors raise substantial doubt about the Company’s ability to continue as a going concern for the twelve months from the date of this report. Management of the Company intends to raise additional funds through the issuance of equity securities or debt. There can be no assurance that, in the event the Company requires additional financing, such financing will be available at terms acceptable to the Company, if at all. Failure to generate sufficient cash flows from operations, raise additional capital and reduce discretionary spending could have a material adverse effect on the Company’s ability to achieve its intended business objectives. As a result, the substantial doubt about the Company’s ability to continue as a going concern has not been alleviated. The accompanying consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. ​ 3.

Borrowings Convertible Promissory Note On August 15, 2022, the Company entered into a Securities Purchase Agreement (the “August Purchase Agreement”), by and between the Company and an institutional investor (the “Investor”), pursuant to which the Company agreed to issue to the Investor a senior secured convertible note in the principal amount of $ 3,600,000 (the “Convertible Note”) and a warrant (the “ August Warrant”) to purchase up to 20,970 shares of the Company’s common stock, at an exercise price of $ 99.70 per share (the “Exercise Price”), in consideration for $ 3,000,000 . Pursuant to the August Purchase Agreement, upon the closing of the private placement, pursuant to which Maxim Group LLC (“Maxim”) acted as placement agent (the “Private Placement”), the Company received gross proceeds of $ 3,000,000 . After the deduction of banker fees, commitment fees and other expenses associated with the transaction, the Company received net proceeds of $ 2,483,000 . The Company used the net proceeds primarily for working capital and general corporate purposes. ​ F-16 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 4. Borrowings, continued The Convertible Note matures on August 15, 2024, does not bear interest and ranks senior to the Company’s existing and future indebtedness and is secured to the extent and as provided in the Security Agreements. The Convertible Note is convertible in whole or in part at the option of the Convertible Note Investor into shares of Common stock (the “Conversion Shares”) at the Conversion Price (as defined below) at any time following the date of issuance of the Convertible Note. The Convertible Note defines “Conversion Price” as equal to the lesser of (a) 90 % of the average of the five lowest daily VWAPs (as defined in the Convertible Note) during the previous twenty trading days prior to delivery to the Company of the Convertible Note Investor’s applicable notice of conversion (the “Conversion Notice”) and(b) $ 92.60 (the “Base Conversion Price”). The Base Conversion Price is subject to full ratchet antidilution protection, subject to a floor conversion price of $ 0.50 per share (the “Floor Price”), a limitation required by the rules and regulations of Nasdaq, and certain exceptions upon any subsequent transaction at a price lower than the Base Conversion Price then in effect and standard adjustments in the event of stock dividends, stock splits, combinations or similar events; provided that in the event the Conversion Price equals the Floor Price, the Company is required to pay the Convertible Note Investor a cash amount determined pursuant to a formula in the Convertible Note, and provided further that the Floor Price will not apply in the event that the Company obtains Stockholder Approval (as defined in the August Purchase Agreement) in accordance with Nasdaq rules. At any time after the closing date of the Private Placement, in the event that the Company issues or sells any shares of common stock or common stock Equivalents (as defined in the Convertible Note), subject to certain exceptions, at an effective price per share lower than the Base Conversion Price then in effect or without consideration, then the Base Conversion Price shall be reduced to the price per share paid for such shares of common stock or common stock Equivalents. Additionally, upon three days ’ written notice to the holder after receipt of a Conversion Notice, in lieu of delivering Conversion Shares, the Company has the right to pay the Convertible Note Investor in cash an amount equal to 105 % of the portion of the outstanding principal amount stated in such Conversion Notice. Further, at the Convertible Note Investor’s option, the Convertible Note is convertible into shares of common stock or redeemable for 103 % of the portion of the outstanding principal amount to be converted in the event that any transaction causes the Conversion Price to be lower than the Floor Price. Subject to certain exceptions, commencing on the Conversion Trigger Date and for a nine-month period after such date, the Convertible Note Investor may convert only up to an aggregate of $ 250,000 in outstanding principal amount during any calendar month, provided, that if Stockholder Approval has been obtained, the Convertible Note is in default at the time or the Company meets certain capitalization conditions, such conversion limitation would not apply. The obligations and performance of the Company under the Convertible Note and the August Purchase Agreement are secured by: (a) a senior lien granted pursuant to security agreements between the Convertible Note Investor and the Company, on (a) all of the assets of the Company (b) a senior lien granted pursuant to trademark security agreements between the Convertible Note Investor and the Company; (c) a senior lien granted pursuant to a patent security agreement between the Convertible Note Investor and the Company on all of the patent assets of the Company; and (d) a pledge of certain securities pursuant to a pledge agreement between the Convertible Note Investor, the Company (such agreements listed in (a)-(d) above, collectively, the “Security Agreements”). The payment and performance obligations of the Company under the Convertible Note and the August Purchase Agreement are guaranteed pursuant to a guaranty by the Company in favor of the Convertible Note Investor. In connection with the Private Placement, the Company issued warrants to the Convertible Note Investor and Maxim to purchase common shares of 20,970 and 1,944 , respectively (see Note 6 – Fair Value Measurements). The sum of the fair value of the warrants, the original issue discount for interest, issuance costs and the derivative liability for the embedded conversion feature for the August 2022 Notes were recorded as debt discounts totaling $ 2,509,000 to be amortized to interest expense over the respective term using the effective interest method. During the year ended December 31, 2022, the Company recognized $ 879,000 of interest expense from the amortization of debt discounts. As of December 31, 2022 the net unamortized debt discounts totaled $ 1,630,000 , and the net carrying value of the convertible note payable was $ 457,000 . In connection with the Private Placement, the Company entered into a placement agency agreement with Maxim (the “Placement Agency Agreement”), and agreed to issue to Maxim, a warrant to purchase up to an aggregate of 1,944 shares of Common Stock (the “Maxim Warrant”) at an exercise price of $ 99.70 per share, which is exercisable at any time on or after the six-month anniversary of the closing date of the Private Placement and will expire on the fifth ( 5 th ) anniversary of its date of issuance. ​ F-17 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 4. Borrowings, continued Effective August 24, 2022, the Company and the Investor agreed to amend Section 3.1(b) of the Convertible Note to provide that the Conversion Price could not be lower than the Floor Price until stockholder approval has been obtained, after which stockholder approval the Floor Price may be reduced to no lower than $ 0.25 , subject to adjustment pursuant to the terms of the August 2022 Note. The changes were effected by cancellation of the Convertible Note and the issuance of a replacement senior secured convertible note (the “New Convertible Note”) to the Investor. The New Convertible Note contains identical terms as the Convertible Note, except for the amendment to the Section 3.1(b). On November 21, 2022, the Company and Maxim entered into an agreement to amend the Maxim Warrant (the “Maxim Warrant Amendment”). Specifically, the Maxim Warrant Amendment sets forth certain circumstances in which the lock up restrictions to which the Maxim Warrant is subject would not apply. The Maxim Warrant Amendment also clarifies certain limitations with respect to demand registration rights, and provides that Maxim’s piggy-back registration rights expire on the fifth ( 5 th) anniversary of the Maxim Warrant’s date of issuance. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Convertible ​ Promissory Note ​ ​ December 31, 2022 ​ December 31, 2021 Convertible note payable ​ $ 2,089 ​ $ — Debt discount ​ ( 1,632 ) ​ — Net total ​ $ 457 ​ $ — ​ The August 2022 Note contains several embedded conversion features. The Company concluded that those conversion features require bifurcation from the Convertible Note and subsequent accounting in the same manner as a freestanding derivative. The Company recognized a derivative liability of $ 286,000 upon execution of the note agreement and such amount was included in the $ 2,509,000 of debt discounts noted above. Subsequent changes in the fair value of these conversion features are measured at each reporting period and recognized in the consolidated statement of operations. The Company recognized expense of $ 47,000 as the change in the fair value of the derivative liability during the year ended December 31, 2022, and the balance of the derivative liability as of December 31, 2022 is $ 333,000 . On November 28, 2022, the Company entered into a waiver of rights (the “Waiver”) with the Convertible Note Investor, pursuant to which the Convertible Note Investor agreed to waive certain prohibitions under the August Purchase Agreement with respect to the offering of units in December 2022 in exchange for the issuance by the Company, on the closing date of such offering, of an additional number of Series A Warrants and an additional number of Series B Warrants equal to the quotient obtained by dividing $ 750,000 by the public offering price for the units sold in the offering (such Warrants, the “Waiver Warrants”). In connection with the public offering the Company consummated on December 1, 2022 (“December 2022 Offering”), the Company issued 53,572 Series A Warrants and 53,572 Series B Warrants to the Convertible Note Investor (See Note 6). The Company’s obligation to issue shares of common stock underlying the Waiver Warrants is expressly conditioned upon stockholder approval of all of the transactions contemplated by the August Purchase Agreement (See Note 11 – Subsequent Events for additional information.) Additionally, as a result of the December 2022 Offering, the Base Conversion Price was adjusted to the Floor Price. ​ F-18 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 4. Borrowings, continued Payroll Protection Program Note Agreement On May 3, 2020, we received a loan (the “PPP Loan”) from Wells Fargo Bank, National Association in the aggregate amount of $ 847,000 , pursuant to the Paycheck Protection Program (the “PPP”) under Division A, Title I of the Coronavirus Aid, Relief, and Economic Security Act, which was enacted on March 27, 2020. The PPP Loan was funded on May 7, 2020. The PPP Loan, which is in the form of a PPP promissory note and agreement, dated May 3, 2020 (the “PPP Note Agreement”), had a maturity date of May 3, 2022 and bore interest at a rate of 1.00 % per annum. Pursuant to a change in guidance by the U.S. Small Business Administration, the initial monthly payment date of the PPP Note Agreement was deferred from November 1, 2020 to August 18, 2021. The PPP Loan could be prepaid by us at any time prior to maturity with no prepayment penalties. During the third quarter of 2021, the Company received full loan forgiveness for obligations related to the PPP Loan. The Company accounted for the PPP Loan as debt, and the loan forgiveness was accounted for as a debt extinguishment. The amount of loan and interest forgiven totaling $ 859,000 , was recognized as a gain upon debt extinguishment and was reported in the accompanying consolidated statements of operations for the year ended December 31, 2021. ​ ​ 5. Fair Value Measurements The Company measures the fair value of financial instruments using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Each level of input has different levels of subjectivity and difficulty involved in determining fair value. ● Level 1 – Inputs used to measure fair value are unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date. Therefore, determining fair value for Level 1 investments generally does not require significant judgment, and the estimation is not difficult. ● Level 2 – Pricing is provided by third-party sources of market information obtained through investment advisors. The Company does not adjust for or apply any additional assumptions or estimates to the pricing information received from its advisors. ● Level 3 – Inputs used to measure fair value are unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The determination of fair value for Level 3 instruments involves the most management judgment and subjectivity. The Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2022 and 2021 by level within the fair value hierarchy, are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ December 31, 2022 ​ ​ ​ Significant ​ ​ ​ ​ Quoted prices ​ other ​ Significant ​ ​ in active ​ observable ​ unobservable ​ ​ markets ​ inputs ​ inputs ​ (Level 1) (Level 2) (Level 3) Liabilities: ​ ​ ​ Derivative liability ​ $ — ​ $ — ​ $ 333 Warrant liabilities ​ $ — ​ $ — ​ $ 8,945 ​ ​ F-19 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 5.

Derivative Liability As described previously in Note 4, the conversion provisions embedded in the Convertible Note require bifurcation and measurement at fair value as a derivative. The fair value was calculated using a Monte Carlo simulation to create a distribution of potential market capitalizations and share prices for the Company on a weekly basis over the assumed period, given the various scenarios. The average value of the Convertible Note was discounted to the valuation date to determine a calibrated discount rate so that the fair value of the Convertible Note was $ 3 million. The value of the Convertible Note was compared with the value of a hypothetical note with no conversion rights in order to determine the fair value of the conversion feature. As of December 31, 2021, the Company did no t have a derivative liability. The Series A Preferred Stock was exchanged for common stock and warrants during the year ended December 31, 2021, thereby eliminating the conversion feature which gave rise to the derivative. Prior to the exchange, the Company had measured the fair value of the derivative by estimating the fair value of the Series A Preferred Stock as if conversion occurred at the end of the reporting period. The Company calculated the value of the conversion feature using the Fixed Conversion Price of the Series A Preferred Stock, as adjusted to 95 % of the volume weighted average price of the common stock for the previous ten trading days constrained by the specified floor price of $ 30.00 . The changes in the fair value of the derivative liability for the years ended December 31, 2022 and 2021 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ For the year ended December 31, (in thousands) 2022 2021 ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ — ​ $ 387 Additions ​ 286 ​ — Change in fair value ​ 47 ​ ( 387 ) Ending balance ​ $ 333 ​ $ — ​ The changes in fair value of the derivative liability are recorded in change in fair value of derivative liability in the consolidated statements of operations. ​ F-20 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 5.

Convertible Preferred Stock and Stockholders’ Equity Series A 8 % Senior Convertible Preferred Stock On April 18, 2019, we entered into a Securities Purchase Agreement, dated as of April 18, 2019, with an investor (the “Preferred Investor”) (the “Preferred SPA”), pursuant to which we issued 250,000 shares of our Series A 8 % Senior Convertible Preferred Stock, par value $ 0.0001 per share (the “Series A Preferred Stock”). In connection with the Preferred SPA, the Company also issued to the Preferred Investor a warrant to purchase 128 shares of our common stock. On June 4, 2021, the Company and the Preferred Investor entered into an exchange agreement pursuant to which the Company exchanged with the Preferred Investor, all outstanding shares of Series A Preferred Stock, for 250,000 shares of common stock and warrants to purchase up to 1,875 shares of common stock. In connection with exchange agreement the Company recorded a deemed dividend of $ 1,192,000 . Immediately following the exchange, the Company no longer had a derivative liability or any preferred stock outstanding. On August 31, 2022, the Company filed an Elimination of Certificate of Designations of the Preferences, Rights and Limitations of the Series A 8 % Senior Convertible Preferred Stock (the “Series A Elimination Certificate”) in order to eliminate and cancel all designations, rights, preferences and limitations of the shares of the Series A 8 % Preferred Stock. Prior to the filing of the Series A Elimination Certificate, none of the 1,250,000 authorized shares of Series A Preferred Stock were issued and outstanding , and no shares of Series A Preferred Stock were to be issued subject to the Series A Certificate of Designations. The Series A Elimination Certificate became effective upon its filing with the Secretary of State of the State of Delaware.

The Company primarily considered such factors as the Company’s history of operating losses; the nature of the Company’s deferred tax assets and the timing, likelihood and amount, if any, of future taxable income during the periods in which those temporary differences and carryforwards become deductible. At present, the Company does not believe that it is “more-likely-than-not” that the deferred tax assets will be realized; accordingly, a full valuation allowance was maintained, and no deferred tax assets were shown in the accompanying consolidated balance sheets. The valuation allowance increased by $ 5,198,000 and $ 3,115,000 during the years ended December 31, 2022 and 2021, respectively. On March 27, 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The CARES Act includes provisions relating to refundable payroll tax credits, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to the tax depreciation methods for qualified improvement property. On December 21, 2020, the U.S. Congress passed the Consolidation Appropriations Act, 2021 (the “CAA Act”). The tax provisions under the CARES Act and CAA Act, do not have a material impact on the consolidated financial statements given the existence of a full valuation allowance. The CARES Act established the Paycheck Protection Program (the “PPP Loan”). Under the terms of the CARES Act, PPP loan recipients can apply for and be granted forgiveness for all or a portion of the loan granted under the PPP Loan. On May 3, 2020, the Company received the PPP loan from Wells Fargo Bank. During the third quarter of 2021, the full amount of the PPP Loan was forgiven. The CARES Act specifically requires taxpayers to exclude canceled indebtedness from gross income, and, accordingly, the debt forgiveness amount was treated as nontaxable. On June 29, 2020, California Assembly Bill 85 (“AB 85”) was signed into law, which suspends the use of California net operating losses and limits the use of California research tax credits for tax years beginning in 2020 and before 2023. However, on February 9, 2022 California Senate Bill 113 (“SB 113”) was signed into law and removed the limitation on the net operating losses and credits for the 2022 year and allows, after taxable years beginning on or after January 1, 2022, the ability to utilize net operating losses and credits. These changes did not have a significant impact on the consolidated financial statements. ​ F-30 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 7. Income Taxes, continued As of December 31, 2022, the Company had federal net operating loss carryforwards of $ 61,968,000 . The federal net operating loss carryforwards will carryforward indefinitely but are subject to the 80 % taxable income limitation. As of December 31, 2022, the Company had state net operating loss carryforwards of $ 60,756,000 which will begin to expire in 2038. Utilization of the Company’s net operating losses and credit carryforwards may be subject to annual limitations in the event of a Section 382 ownership change. Such future limitations could result in the expiration of net operating losses and credit carryforwards before utilization as a result of such an ownership change. Provision for income taxes for the years ended December 31, 2022 and 2021 differed from the amounts computed by applying the statutory federal income tax rate of 21 % to the loss before provision for income taxes as a result of the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ 2022 2021 Effective tax rate reconciliation: ​ Income tax provision at statutory rate 21.0 % 21.0 % State taxes, net of federal benefit — — ​ Other permanent differences 3.5 ( 8.0 ) ​ Change in valuation allowance ( 24.5 ) ( 20.2 ) ​ Provision for income taxes — % — % ​ Tax positions are evaluated in a two-step process. The Company first determines whether it is “more-likely-than-not” that a tax position will be sustained upon examination. If a tax position meets the “more-likely-than-not” recognition threshold it is then measured to determine the amount of benefit to recognize in the consolidated financial statements. The tax position is measured as the largest amount of benefit that is greater than 50 % likely of being realized upon ultimate settlement. The aggregate changes in the balance of gross unrecognized tax benefits, which excludes interest and penalties, for the years ended December 31, 2022 and 2021 is zero . The Company has not incurred any material tax interest or penalties as of December 31, 2022. The Company does not anticipate any significant change within 12 months of this reporting date of its uncertain tax positions. The Company is subject to taxation in the United States and various state jurisdictions. There are no ongoing examinations by taxing authorities at this time. The Company’s various tax years 2018 through 2022 remain open for examination by the federal and state authorities for three and four years , respectively, from the date of utilization of any net operating loss carryforwards. The Company recognizes interest and penalties related to uncertain tax positions in the provision for income taxes. As of December 31, 2022 and 2021, the Company has not accrued any penalties or interest related to uncertain tax positions. ​ ​ ​ 8. Commitments and Contingencies Operating Leases The Company leases office space under a non-cancellable operating lease that expires in January 2024 and has an option to renew this lease, with renewal rates to be negotiated. Operating lease rentals are expensed on a straight-line basis over the life of the lease beginning on the date we take possession of the property. At lease inception, we determine the lease term by assuming the exercise of those renewal options that are reasonably assured. The exercise of lease renewal options is at our sole discretion. The lease term is used to determine whether a lease is financing or operating and is used to calculate straight-line rent expense. Additionally, the depreciable life of leasehold improvements is limited by the expected lease term. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheets; we recognize lease expense for these leases on a straight-line basis over the lease term.

Management Team Retention Bonus On September 1, 2022, the “Company adopted its Management Team Retention Bonus Plan (the “Retention Plan”), to incentivize certain management level employees (the “Managers”) to remain intact through and shortly following a potential “Change of Control” (as defined in the Retention Plan). The aggregate Retention Plan bonus amounts for all Managers is $ 1,250,000 . The Retention Plan provides that each Manager is eligible to receive a lump sum cash amount under the Retention Plan, on the earlier of the six-month anniversary of the date of a Change of Control or at the time of such Manager’s involuntary termination other than for “Cause” (as defined in the Retention Plan) or termination for “Good Reason” (as defined in the Retention Plan). The Retention Plan will terminate upon the earlier of June 30, 2023 if a Change of Control has not occurred by such date or upon the payment of all Retention Bonus Amounts. As of December 31, 2022, no accrual has been made under the Retention Plan. Contingencies In the normal course of business, the Company may become involved in legal proceedings. The Company will accrue a liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When only a range of a possible loss can be established, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. The accrual for a litigation loss contingency might include, for example, estimates of potential damages, outside legal fees and other directly related costs expected to be incurred. The Company’s management does not believe that any such matters, individually or in the aggregate, will have a materially adverse effect on the Company’s consolidated financial statements. ​ F-33 Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the years ended December 31, 2022 and 2021 9.
