NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS For the Three Months Ended March 31, 2022 and 2021 (unaudited) 1. 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. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to Article 10 of Regulation S-X of the Securities Act of 1933, as amended (“Securities Act”). Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated financial statements include all normal and recurring adjustments that the Company believes are necessary to fairly state the Company’s financial position and the results of operations and cash flows. Interim period results are not necessarily indicative of results of operations or cash flows for a full year or any subsequent interim period. The condensed consolidated balance sheet as of December 31, 2021 has been derived from audited consolidated financial statements at that date, but does not include all disclosures required by U.S. GAAP for complete financial statements. 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’ condensed 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 as necessary, and sometimes requires partial payment in advance of shipping. As of March 31, 2022 and December 31, 2021, there was no allowance for doubtful accounts. As of March 31, 2022, the Company had four customers accounting for 34 %, 23 %, 18 % and 10 % of accounts receivable. As of March 31, 2021, the Company had four customers accounting for 33 %, 30 %, 16 % and 11 % of accounts receivable. As of December 31, 2021, the Company had two customers accounting for 35 %, and 27 % of accounts receivable. The Company had three customers accounting for 36 %, 25 % and 16 % of its net revenue for the three months ended March 31, 2022. The Company had five customers accounting for 37 %, 12 %, 12 %, 11 % and 11 % of its net revenue for the three months ended March 31, 2021. 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. 7 Table of Contents WISA TECHNOLOGIES, INC. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS For the Three Months Ended March 31, 2022 and 2021 (unaudited) 1. Summary of Significant Accounting Policies, continued 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. 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 March 31, 2022 and 2021, the Company had capitalized $ 125,000 and $ 0 , respectively, of deferred offering costs in prepaid expenses and other current assets on the condensed consolidated balance sheet. 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. Warrants for Shares of Common Stock and Derivative Financial Instruments Warrants for 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 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. 8 Table of Contents WISA TECHNOLOGIES, INC. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS For the Three Months Ended March 31, 2022 and 2021 (unaudited) 1. Summary of Significant Accounting Policies, continued 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 condensed 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. During the three months ended March 31, 2022 and 2021, net revenue consisted of the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three Months Ended March 31, (in thousands) ​ 2022 ​ 2021 Components ​ $ 301 ​ $ 990 Consumer Audio Products ​ 265 ​ 163 Total ​ $ 566 ​ $ 1,153 ​ 9 Table of Contents WISA TECHNOLOGIES, INC.

Summary of Significant Accounting Policies, continued Contract Balances We receive payments from customers based on a billing schedule as established in our contracts to partially offset prepayments required by our vendors on long lead time materials. Amounts collected prior to the fulfillment of the performance obligation are considered contract liabilities and classified as customer advances within accrued liabilities on the condensed 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 March 31, 2022 and December 31, 2021. (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ 2022 2021 Contract liabilities ​ $ 265 ​ $ — ​ 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 condensed 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. 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. 10 Table of Contents WISA TECHNOLOGIES, INC. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS For the Three Months Ended March 31, 2022 and 2021 (unaudited) 1. Summary of Significant Accounting Policies, continued Advertising Costs Advertising costs are charged to sales and marketing expenses as incurred. Advertising costs for the three months ended March 31, 2022 and 2021 were $ 171,000 and $ 132,000 , 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 three months ended March 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 condensed consolidated statement of operations in other income (expense), net and were not material for the three months ended March 31, 2022 and 2021. Net Loss per Common Share 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 shares of common stock 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 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 three months ended March 31, 2022, warrants to purchase 4,474,303 shares of common stock, 1,568,725 shares of restricted stock, 297,083 shares of restricted stock issued under an inducement grant and 427,391 shares underlying restricted stock units have been excluded from the calculation of net loss per common share because the inclusion would be antidilutive. For the three months ended March 31, 2021, warrants to purchase 5,530,600 shares of common stock, 250,000 shares of convertible preferred stock, 730,869 shares of restricted stock awards and 643,974 shares of restricted stock units have been excluded from the calculation of net loss per common share because the inclusion would be antidilutive. Recently Adopted Accounting Pronouncements. Adoption of ASC 842 The Company adopted FASB’s 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. 11 Table of Contents WISA TECHNOLOGIES, INC. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS For the Three Months Ended March 31, 2022 and 2021 (unaudited) 1. Summary of Significant Accounting Policies, continued 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 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. The effect of the changes made to our consolidated January 1, 2022 balance sheet for the adoption of the new lease standard was as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance as of Adjustments Balance as of ​ ​ December 31, 2021 ​ Due to ASC 842 ​ January 1, 2022 Operating lease right-of-use assets ​ $ — ​ $ 212 ​ $ 212 Property and equipment, net ​ ​ 162 ​ ​ 90 ​ ​ 252 Total assets ​ $ 19,391 ​ $ 302 ​ $ 19,693 Operating lease liabilities, current ​ $ — ​ $ 148 ​ $ 148 Operating lease liabilities, non-current ​ $ — ​ $ 179 ​ $ 179 Deferred rent and lease incentive ​ $ 58 ​ $ ( 58 ) ​ $ — Total liabilities ​ $ 3,014 ​ $ 269 ​ $ 3,283 Accumulated deficit ​ $ ( 212,203 ) ​ $ 33 ​ $ ( 212,170 ) Total stockholders’ equity ​ $ 16,377 ​ $ 33 ​ $ 16,410 Total liabilities and stockholders’ equity ​ $ 19,391 ​ $ 302 ​ $ 19,693 ​ Recently Issued and Not Yet Adopted Accounting Pronouncements In August 2020, the FASB issued ASU 2020-06 “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity”. 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 condensed 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 condensed 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 condensed consolidated financial statements as a result of future adoption. ​ ​ ​ 12 Table of Contents WISA TECHNOLOGIES, INC. NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS For the Three Months Ended March 31, 2022 and 2021 (unaudited) 2. Going Concern The condensed 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 March 31, 2022, the Company had cash and cash equivalents of $ 9.1 million and reported net cash used in operations of $ 4.0 million during the three months ended March 31, 2022. In December 2021, the Company entered into an “at-the-market” sales agreement with Maxim Group LLC (the “Agent”), pursuant to which the Company may sell from time to time, shares of its common stock having an aggregate offering price of up to $ 4.5 million through the Agent. As of March 31, 2022, the Company has not sold any shares of common stock under the ATM Program. 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 by selling additional equity or incurring debt. To date, the Company has funded its operations primarily through sales of its common stock in public markets, sales of common and preferred units prior to its initial public offering (“IPO”), and 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 condensed consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. ​ 3.

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 March 31, 2022 and December 31, 2021 by level within the fair value hierarchy, are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ March 31, 2022 ​ ​ ​ ​ Significant ​ ​ ​ ​ ​ Quoted prices ​ other ​ Significant ​ ​ in active ​ observable ​ unobservable ​ ​ markets ​ inputs ​ inputs ​ (Level 1) (Level 2) (Level 3) Liabilities: ​ ​ ​ ​ ​ ​ Warrant liability ​ $ — ​ $ — ​ $ 8 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ December 31, 2021 ​ ​ ​ ​ Significant ​ ​ ​ ​ ​ Quoted prices ​ other ​ Significant ​ ​ in active ​ observable ​ unobservable ​ ​ markets ​ inputs ​ inputs ​ (Level 1) (Level 2) (Level 3) Liabilities: ​ ​ ​ ​ ​ ​ Warrant liability ​ $ — ​ $ — ​ $ 8 ​ There were no transfers between Level 1, 2 or 3 during the three months ended March 31, 2022 or March 31, 2021. 15 Table of Contents WISA TECHNOLOGIES, INC.

The Company also recognizes the effect of changes in enacted tax laws or rates in the interim periods in which the changes occur. As of March 31, 2022 and December 31, 2021, the Company retains a full valuation allowance on its deferred tax assets. The realization of the Company’s deferred tax assets depends primarily on its ability to generate taxable income in future periods. The amount of deferred tax assets considered realizable in future periods may change as management continues to reassess the underlying factors it uses in estimating future taxable income. The provision for income taxes for the three months ended March 31, 2022 and 2021 was calculated on a jurisdiction basis. ​ 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 condensed consolidated balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term.

Commitments and Contingencies, continued 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 condensed consolidated financial statements. ​ 9.
