Basis of Presentation

The accompanying condensed 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 condensed 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

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 June 30, 2024 and December 31, 2023, there was no allowance for credit losses. As of June 30, 2024, the Company had four customers accounting for 43%, 33%, 12%and 11% of accounts receivable. As of December 31, 2023, the Company had two customers accounting for 71% and 20% of accounts receivable.

The Company had four customers accounting for 33%, 27%, 20% and 11% of its net revenue for the three months ended June 30, 2024. The Company had four customers accounting for 28%, 27%, 19% and 10% of its net revenue for the six months ended June 30, 2024. The Company had four customers accounting for 35%, 13%, 12% and 11% of its net revenue for the three months ended June 30, 2023. The Company had two customers accounting for 29% and 17% of its net revenue for the six months ended June 30, 2023.

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 Credit Losses

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.

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 liabilities are the only financial instrument that is 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.

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.

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 Common Shares, Convertible Redeemable Preferred Shares, and Derivative Financial Instruments

Warrants for our common shares, convertible redeemable preferred shares, and 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) 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.

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.

Practical Expedients and Exemptions

In accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, we 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.

Contract Balances

The Company receives 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 consolidated balance sheets. Contract assets are recorded when the Company has a conditional right to consideration for our completed performance under the contracts. Accounts receivables are recorded when the right to this consideration becomes unconditional. The Company does not have any material contract assets as of June 30, 2024 and December 31, 2023. During the six month ended June 30, 2024, the Company did not recognize any revenue that was included in the contract liabilities balance as of December 31, 2023.

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.

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 three and six months ended June 30, 2024 were $117,000 and $264,000, respectively. Advertising costs for the three and six months ended June 30, 2023 were $118,000 and $273,000, 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 and six months ended June 30, 2024 and 2023, 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 and six months ended June 30, 2024 and 2023.

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.

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. Net loss is adjusted for any deemed dividends to preferred stockholders to compute income available to common stockholders.

As of June 30, 2024, warrants to purchase 9,793,531 shares of common stock, 260,441 shares of restricted stock, 16 shares of restricted stock issued under an inducement grant and 14 shares underlying restricted stock units, have been excluded from the calculation of net loss per common share because the inclusion would be antidilutive.

As of June 30, 2023, warrants to purchase 37,572 shares of common stock, 69 shares of restricted stock, 18 shares of restricted stock issued under an inducement grant and 36 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 June 30, 2024 and December 31, 2023. 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 condensed 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. As of June 30, 2024 and December 31, 2023, the Company recognized no interest and penalties.

Recently Adopted Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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. The Company adopted this standard on January 1, 2024 using the modified retrospective method by applying the ASU to financial instruments outstanding as of January 1, 2024, with the cumulative effect of adoption recognized at that date through an adjustment to the opening balance of retained earnings. As such, the Company adopted the standard by eliminating any unamortized discount to the Series B Preferred Stock for the beneficial conversion feature. The cumulative effect of ASU 2020-06 adoption adjusted against additional paid-in-capital due to the absence of retained earnings on January 1, 2024 amounted to $116,000.

Recently Issued and Not Yet Adopted Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09 – Income Taxes (Topic 740): Improvements to Income Tax Disclosures” to help investors better understand an entity’s exposure to potential changes in jurisdictional tax legislation and the ensuing risks and opportunities. Furthermore, the Update improves disclosures used to assess income tax information that affects cash flow forecasts and capital allocation decisions. The Update is effective for public business entities for annual periods beginning after December 15, 2024, on a prospective basis. The Company is currently evaluating the impact of the adoption of this standard on our condensed consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” aiming to enhance the transparency and relevance of segment information provided in financial statements. The amendments in this Update require that a public entity disclose significant segment expenses, profit or loss and assets, etc. for each reportable segment, on an annual and interim basis. The Update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of the adoption of this standard on our 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.

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. As of June 30, 2024, the Company had cash and cash equivalents of $6.1 million and reported net cash used in operations of $9.0 million during the six months ended June 30, 2024. 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 attain 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 and private 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 condensed consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.

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 “Convertible Note 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 to purchase up to 140 shares of the Company’s common stock, at an initial exercise price of $14,955.00 per share, 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.

The Convertible Note matured 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 and (b) $13,890.00 (the “Base Conversion Price”). The Base Conversion Price is subject to full ratchet antidilution protection, subject to a floor conversion price of $75.00 per share (the “Floor Price”).

In connection with the Private Placement, the Company issued warrants to the Convertible Note Investor and Maxim to purchase common shares of 140 and 13, respectively (see Note 5 – 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 Convertible Note 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, 2023, the Company recognized $737,000 of interest expense from the amortization of debt discounts and repayment of the convertible note payable in April 2023.

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 13 shares of Common Stock (the “Maxim Warrant”) at an initial exercise price of $14,955.00 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.

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 $37.50, subject to adjustment pursuant to the terms of the Convertible 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 (5th) anniversary of the Maxim Warrant’s date of issuance.

The New Convertible Note contained several embedded conversion features. The Company concluded that those conversion features require bifurcation from the New 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.

On November 28, 2022, the Company entered into a waiver of rights (the “Waiver”) with the New Convertible Note Investor, pursuant to which the New 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 to purchase shares of Common Stock (“Series A Warrants”) and an additional number of Series B warrants to purchase shares of Common Stock (“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 (the “December 2022 Offering”), the Company issued 357 Series A Warrants and 357 Series B Warrants to the New 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. At a Special Meeting of Stockholders held on January 24, 2023, the Company received stockholder approval of the transactions contemplated by the August Purchase Agreement. Additionally, as a result of the December 2022 Offering, the Base Conversion Price was adjusted to the Floor Price.

On February 1, 2023, the holder of the New Convertible Note converted approximately $708,000, a portion of the outstanding principal amount into 450 shares of the Company’s common stock.

On April 11, 2023, the Company paid $1,656,744 to the holder of the New Convertible Note which repaid the entirety of the outstanding balance and included the unpaid principal, interest through the payoff date, and a pre-payment premium of $276,000 which was recorded as a component of loss on debt extinguishment.

September 2023 Short-Term Loan Agreement

On September 8, 2023, the Company entered into that certain Loan and Security Agreement with the Meriwether Group Capital Hero Fund LP (“Meriwether Hero Fund”). Pursuant to the Loan and Security Agreement, the Meriwether Hero Fund agreed to provide the Company with bridge financing in the form of a term loan in the original principal amount of $650,000, which term loan will be senior in priority to the Company’s present and future indebtedness (“Meriwether Loan”). The Meriwether Loan was to mature on November 7, 2023, subject to further extension. In addition, the Company had the right to request additional funding under the Loan and Security Agreement.

Borrowings under the Meriwether Loan bore interest at a rate per annum equal to 18%. On the maturity date, subject to any extension, the Company was obligated to make a payment equal to all unpaid principal and accrued interest. Pursuant to Meriwether Loan, the Company was required to pay to the Meriwether Hero Fund a fully earned, non-refundable, origination fee in the amount of$50,000. The Company was also required to pay to the Meriwether Hero Fund a fully earned, non-refundable, exit fee in the amount of $50,000 due and payable on the maturity date.

The Meriwether Loan also provided that all present and future indebtedness and the obligations of the Company to the Meriwether Hero Fund shall be secured by a first priority security interest in all real and personal property collateral of the Company.

The Meriwether Loan contained customary representations, warranties and affirmative and negative covenants. In addition, the Meriwether Loan contained customary events of default that entitle the Meriwether Hero Fund to cause the Company’s indebtedness under the Meriwether Loan to become immediately due and payable, and to exercise remedies against the Company and the collateral securing the term loan.

On October 10, 2023, the Meriwether Hero Fund, agreed to extend the Meriwether Loan maturity date from November 7, 2023 to December 7, 2023, for a fee of $20,000.

On December 7, 2023, the Company repaid the full amount of the Meriwether Loan, including all fees and accrued interest.

January 2024 Short-Term Loan Agreement

On January 19, 2024, the Company issued promissory notes in the aggregate principal amount of $1,000,000 (the “January 2024 Promissory Notes”) and common stock purchase warrants to purchase up to an aggregate of 66,665 shares (the “January 2024 Warrant Shares”) of the Company’s common stock, at an initial exercise price of $22.23 per share with four accredited investors (each an “Investor” and together the “Investors”). In connection with the January 2024 Promissory Notes, the Company received gross proceeds of $600,000, before fees and other expenses associated with the transaction.

The January 2024 Promissory Note was to mature on the earlier to occur of: (i) July 17, 2024 and (ii) the full or partial exercise of certain Series B Preferred Stock purchase warrants currently held by the Investor, issuable for at least 9,322 shares of the Company’s Series B Convertible Preferred Stock, par value $0.0001 per share (“Series B Preferred Stock”), upon such full or partial exercise. The January 2024 Promissory Notes did not bear interest except upon the occurrence of an Event of Default (as defined in the January 2024 Promissory Notes). The January 2024 Promissory Notes were not convertible into shares of Common Stock or Series B Preferred Stock.

Between the dates of January 26, 2024 and February 2, 2024, the January 2024 Promissory Notes were repaid in full following the exercise of certain of the Company’s Series B Preferred Stock purchase warrants for a total of 29,322 shares of Series B Preferred Stock. The 2024 Promissory Notes were settled via the payment of $667,000 in cash and a $333,000 offset to the amount due by one of the investors from the exercise of 9,322 Series B Preferred Stock purchase warrants.

In connection with the issuance of the January 2024 Warrant Shares (see Note 5 – Fair Value Measurements), the fair value of the warrants and the original issue discount for interest were recorded as debt discounts totaling $1,260,000. The debt discounts were to be amortized to interest expense over the respective term using the effective interest method. In connection with the full repayment of the January 2024 Promissory Notes, the Company recognized $1,260,000 of interest expense in the six months ended June 30, 2024.

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 June 30, 2024 and December 31, 2023 by level within the fair value hierarchy, are as follows:

Warrant Liabilities

The following table includes a summary of changes in fair value of the Company’s warrant liabilities measured at fair value using significant unobservable inputs (Level 3) as of June 30, 2024 and 2023. For June 30, 2024, the fair value of the common warrants was determined using the Black-Scholes Model based on the following key inputs and assumptions: common stock price of $2.57; exercise prices between $3.196 and $1,574.00; expected yield of 0.0%; expected volatility of 143%; risk-free interest rate of 4.52% and expected life between 3.1 and 3.6 years.

During the three months ended June 30, 2024, the Company amended the terms of certain warrant agreements to remove certain exercise price reset, right to reprice and/or share adjustment provisions (“Reset Provisions”) following a reverse split, in addition to other revisions to the warrants. In April 2024, the Company effected the April 2024 Reverse Stock Split thereby removing the Reset Provisions (“Reset Amendment Effective Date”) and in accordance with provisions in certain of the warrants issued warrants to purchase an additional 5,602,693 shares of common stock. Accordingly, the Company remeasured the warrant liability for each of the amended warrants following the Reset Amendment Effective Date and recorded that amount to change in fair value of warrant liabilities with a corresponding increase to warrant liabilities. Following the Reset Amendment Effective Date, such warrants were no longer deemed to be liability warrants but were now classified as equity warrants. In connection with this reclassification the Company reclassed approximately $41.9 million from warrant liabilities to additional paid in capital.

6.	Convertible Redeemable Preferred Stock and Stockholders’ Equity

Series B Preferred Stock, Series B Preferred Stock Warrants

On October 16, 2023, the Company consummated a public offering for an aggregate of 87,000 Series B Units (“Series B Units”). Each Series B Unit consists of one share of the Company’s Series B Preferred Stock and two warrants, each to purchase one share of Series B Preferred Stock (“Series B Preferred Stock Warrant”). Each share of Series B Preferred Stock is convertible at the holder’s option at any time, through a two-year period, into the number of shares of the Company’s common stock determined by dividing the $100 stated value per share of the Series B Preferred Stock by a conversion price of $62.205 per share. Each share of Series B Preferred Stock is convertible into 1 share of common stock, and each Series B Preferred Stock Warrant entitles the holder to purchase one share of Series B Preferred Stock at an initial exercise price of $55 per share. Dividends are paid in additional fully paid and nonassessable Series B Preferred Stock, at a 20% dividend rate, non-cumulative. If any shares of Series B Preferred Stock are outstanding at the end of the two-year period, the holder would be entitled to a cash redemption value equal to the $100 stated value per share. The gross proceeds from the sale of Series B Units were $4,785,000, before broker fees and related expenses of approximately $830,000.

Exercise of Series B Preferred Stock Warrants

On December 5, 2023, the Company executed an Inducement Agreement (the “Inducement Agreement”) with the holders of Series B Preferred Stock Warrants, reducing the exercise price to $35.72 per share of Series B Preferred Stock. Any holder that exercised Series B Preferred Stock Warrants under the Inducement Agreement received a new Common Stock Warrant (“New Common Stock Warrants”) for each Series B Preferred Stock Warrant exercised. Each New Common Stock Warrant entitles the holder to purchase 2 shares of common stock at an initial exercise price of $22.23 per share.

Due to certain price protections included with the New Common Stock Warrants, the warrants did not meet the criteria for equity classification and thus are subject to liability treatment. Total proceeds from the exercise of 61,613 Series B Preferred Stock Warrants of $2,264,000 through December 31, 2023, and the remaining fair value of the Series B Preferred Stock Warrant liability immediately prior to the exercise of $1,628,000 resulted in a total of $3,892,000 recorded for the new 61,613 shares of Series B Preferred Stock, of which $3,322,000 was allocated to the Common Stock Warrants liability based on their fair value and $569,000 was allocated to the Series B Preferred Stock using the residual method of allocation. In connection with this new issuance, the Company has recorded additional discounts to the Series B Preferred Stock for a beneficial conversion feature of $196,000, the Common Stock Warrants of $3,322,000 and issuance costs of $146,000. The Company also accretes to Series B Preferred Stock, against additional paid in capital as a deemed dividend, for the difference between the total proceeds of $35.72 per share of Series B Preferred Stock and the full redemption price of $100 per share. The Company uses the effective interest method to calculate the accretion amount for each period. All 61,613 New Common Stock Warrants issued as a result of the exercise of Series B Preferred Stock Warrants were outstanding as of December 31, 2023.

Issuance costs of $429,000 and $125,000 were expensed on the date of issuance of the Series B Preferred Stock Warrants and the New Common Stock Warrants, respectively as such warrants were recorded at fair value. Total issuance costs expensed from the issuances were charged to Change in fair value of warrant liabilities and amounted to $554,000.

Under the LTIP, 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. At a Special Meeting of Stockholders on January 24, 2023, the Company’s 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. At a Special Meeting of Stockholders on March 15, 2024, the Company’s stockholders further approved an amendment to the LTIP to increase the annual share limit of Common Stock that may be issued only for the 2024 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).

7.	Income Taxes

The Company recorded no provision for income taxes for the three and six months ended June 30, 2024. The Company recorded a provision for income taxes of $2,000 and $2,000 for the three and six months ended June 30, 2023, respectively.

The Company’s effective tax rate was 0.0% for the three and six months ended June 30, 2024 and 2023. The difference between the effective tax rate and the federal statutory tax rate for the three and six months ended June 30, 2024 and 2023 primarily relates to the valuation allowance on the Company’s deferred tax assets.

For interim periods, the Company estimates its annual effective income tax rate and applies the estimated rate to the year-to-date income or loss before income taxes. The Company also computes the tax provision or benefit related to items reported separately and recognizes the items net of their related tax effect in the interim periods in which they occur. 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 June 30, 2024 and December 31, 2023, 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 and six months ended June 30, 2024 and 2023 was calculated on a jurisdiction basis.

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.

The following table reflects our lease assets and our lease liabilities at June 30, 2024 and December 31, 2023 (in thousands):

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.

To date, our operations have been funded through sales of our common and preferred equity, proceeds from the exercise of warrants to purchase common stock, sale of debt instruments, and revenue from the sale of our products. Our condensed consolidated financial statements contemplate the continuation of our business as a going concern. However, we are subject to the risks and uncertainties associated with an emerging business, as noted above we have no established source of capital, and we have incurred recurring losses from operations since inception.

Comparison of the Three and Six Months Ended June 30, 2024 and 2023

Revenue

Revenue for the three months ended June 30, 2024 was $345,000 a decrease of $80,000 or 19% compared to the revenue for the three months ended June 30, 2023 of $425,000. The decrease was a result of lower Consumer Audio Product sales which decreased by $81,000 compared to the three months ended June 30, 2023. The decrease in sales is primarily related to fewer products sold (due in part to a slowdown in spending on consumer electronics.)

Table of Contents

Revenue for the six months ended June 30, 2024 was $600,000 a decrease of $294,000 or 33% compared to the revenue for the six months ended June 30, 2023 of $894,000. The decrease was a result of lower Component revenue which decreased by $167,000 compared to the six months ended June 30, 2023, and lower Consumer Audio Product sales, which decreased by $127,000, compared to the six months ended June 30, 2023. The decrease in overall sales is primarily related to fewer products sold (due in part to a slowdown in spending on consumer electronics.)

Gross Profit and Operating Expenses

Gross Profit (Deficit)

Gross profit for the three months ended June 30, 2024 was $11,000 compared to a gross deficit of ($201,000) for the three months ended June 30, 2023. The gross margin as a percent of sales was 3% for the three months ended June 30, 2024, compared to (47%) for the three months ended June 30, 2023. The improvement in gross profit and gross margin as a percent of sales compared to the prior period is mainly attributable to the fact that the three months ended June 30, 2023 included a $169,000 increase in inventory reserves as a result of certain excess raw materials, primarily attributable to the out of balance inventory associated with longer lead time semiconductor chips, whereas the three months ended June 30, 2024 did not have any increases to inventory reserves.

Gross deficit for the six months ended June 30, 2024 was ($72,000), compared to a gross deficit of ($1,454,000) for the six months ended June 30, 2023. The improvement in gross deficit between periods is mainly attributable to lower cost of revenue of sales. The gross margin as a percent of sales was (12%) for the six months ended June 30, 2024, compared to (163%) for the six months ended June 30, 2023. The improvement in gross deficit and gross margin as a percent of sales compared to the prior period is mainly attributable to the fact that the six months ended June 30, 2023 included a $1.4 million increase in inventory reserves as a result of certain excess raw materials, primarily attributable to the out of balance inventory associated with longer lead time semiconductor chips, whereas the six months ended June 30, 2024 did not have any increases to inventory reserves.

Research and Development

Research and development expenses for the three months ended June 30, 2024 were $1,789,000, a decrease of $144,000, compared to the research and development expenses for the three months ended June 30, 2023 of $1,933,000. The decrease in research and development expenses is primarily related to decreased legal fees and consulting expenses of $77,000 and $68,000, respectively.

Research and development expenses for the six months ended June 30, 2024 were $3,504,000, a decrease of $322,000 compared to the research and development expenses for the six months ended June 30, 2023 of $3,826,000. The decrease in research and development expenses is primarily related to decreased consulting expenses, which includes outside engineering, reduced legal fees and reduced stock based compensation of $165,000, $82,000 and $69,000, respectively.

Sales and Marketing

Sales and marketing expenses for the three months ended June 30, 2024 were $865,000, a decrease of $224,000 compared to the sales and marketing expenses for the three months ended June 30, 2023 of $1,089,000. The decrease in sales and marketing expenses is primarily related to decreased salary and benefit expense of $134,000 and decreased website expenses of $66,000.

Sales and marketing expenses for the six months ended June 30, 2024 were $1,794,000, a decrease of $589,000 compared to the sales and marketing expenses for the six months ended June 30, 2023 of $2,383,000. The decrease in sales and marketing expenses is primarily related to decreased salary and benefit expense of $308,000 and decreased website expenses, consulting expenses and public relations expenses of $138,000, $56,000 and $42,000, respectively.

General and Administrative

General and administrative expenses for the three months ended June 30, 2024 were $2,762,000, an increase of $1,292,000 compared to the general and administrative expenses for the three months ended June 30, 2023 of $1,470,000. The increase in general and administrative expenses is primarily related to increased investor relations expenses of $1,015,000, which includes stock-based compensation charges of $156,000, and increased legal fees and shareholder expenses of $244,000 and $103,000, respectively, offset partially by decreased stock-based compensation expense of $165,000.

Table of Contents

General and administrative expenses for the six months ended June 30, 2024 were $4,193,000, an increase of $1,361,000, compared to the general and administrative expenses for the three months ended June 30, 2023 of $2,832,000. The increase in general and administrative expenses is primarily related to increased investor relations expenses of $1,304,000, which includes stock-based compensation charges of $156,000, and increased legal fees and shareholder expenses of $134,000 and $131,000, respectively, offset partially by decreased stock-based compensation expense of $253,000.

Interest Expense, net

Interest expense, net for the three months ended June 30, 2024 was $4,000, a decrease of $33,000 compared to the interest expense for the three months ended June 30, 2023 of $37,000. Interest expense, net for the six months ended June 30, 2024 was $1,269,000, an increase of $509,000 compared to the interest expense for the six months ended June 30, 2023 of $760,000.

The increase in interest expense, net for the six months ended June 30, 2024, was primarily due to the amortization of debt discounts associated with the January 2024 Promissory Note in the principal amount of $1,000,000 that the Company incurred in January 2024 and repaid in full in January 2024.

Change in Fair Value of Warrant Liability

Change in fair value of warrant liability for the three months ended June 30, 2024 was a loss of $37,255,000, compared to a gain of $246,000 for the three months ended June 30, 2023. The change in fair value of the warrant liability for the three months ended June 30, 2024 was due to the issuance of additional warrants to purchase 5,602,693 shares of common stock and the subsequent valuing of such warrants. The additional warrants were issued as a result of provision in certain of the warrant agreements that was triggered following the Company’s reverse stock split that occurred in April 2024.

Change in fair value of warrant liability for the six months ended June 30, 2024 was a loss of $29,126,000 compared to a gain of $5,850,000 for the six months ended June 30, 2023. The change in fair value of the warrant liability for the six months ended June 30, 2024 was due to the issuance of additional warrants to purchase 5,602,693 shares of common stock and the subsequent valuing of such warrants. The additional warrants were issued as a result of provision in certain of the warrant agreements that was triggered following the Company’s reverse stock split that occurred in April 2024.

Liquidity and Capital Resources

Cash and cash equivalents as of June 30, 2024 were $6,113,000 compared to $411,000, as of December 31, 2023.

We recorded a net loss of $39,958,000 for the six months ended June 30, 2024 and used net cash in operating activities of $9,045,000. We incurred a net loss of $6,247,000 for the six months ended June 30, 2023 and used net cash in operating activities of $9,126,000. Excluding non-cash adjustments, the primary reasons for the increase in the use of net cash from operating activities during the six months ended June 30, 2024, was related to an increase in prepaid expenses and decrease in accounts payable, partially offset by a decrease in inventories.

We have financed our operations to date primarily through the issuance of equity securities, proceeds from the exercise of warrants to purchase common stock and sale of debt instruments. In January 2024, we received gross proceeds of $600,000 from the issuance of promissory notes and common stock purchase warrants to certain accredited investors. In February 2024, we received gross proceeds of approximately $10.0 million from the public offering of 1,025,600 units, with each unit consisting of one share of common stock (or pre-funded warrant in lieu thereof) and one warrant, each to purchase one (1) share of common stock. In March 2024 we received net proceeds of approximately $2.3 million from the issuance of 417,833 shares of common stock, 93,342 pre-funded common stock warrants and the issuance of 511,175 warrants to purchase common stock. On April 19, 2024, we received net proceeds of approximately $591,000 from the issuance of 225,834 shares of common stock and the issuance of 225,834 warrants to purchase common stock. On April 23, 2024, we received net proceeds of approximately $1.6 million from the issuance of 361,904 shares of common stock and the issuance of 542,856 warrants to purchase common stock. On April 30, 2024, we received net proceeds of approximately $2.1 million from the issuance of 418,845 shares of common stock and the issuance of 418,845 warrants to purchase common stock. On May 15, 2024, we received net proceeds of approximately $2.3 million from the issuance of 785,000 shares of common stock and the issuance of 785,000 warrants to purchase common stock. On May 17, 2024, we received net proceeds of approximately $2.1 million from the issuance of 675,000 shares of common stock and the issuance of 675,000 warrants to purchase common stock. We will need to raise additional proceeds via the issuance of equity securities and/or the sale of debt instruments in the fourth quarter of 2024 to fund operations for fiscal year 2025.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

As a smaller reporting company, as defined in Rule 12b-2 of the Exchange Act, we are not required to provide the information required by this Item.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that material information required to be disclosed in our periodic reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission (“SEC”) rules and forms and to ensure that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of our disclosure controls and procedures. Based on the foregoing evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2024, our disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Our management, including our Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), does not expect that our disclosure controls and procedures will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our Company have been detected. These inherent limitations include, but are not limited to, the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Changes in Internal Controls

There were no changes in the Company’s internal control over financial reporting that occurred during the three months ended June 30, 2024 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.
