CONVERTIBLE NOTES AND NOTE PAYABLE

8. CONVERTIBLE NOTES AND NOTE PAYABLE

2020 Convertible Notes

In May 2020, the Company issued a convertible promissory note (“May Note”) to a Lender in exchange for $25,000 in cash proceeds. The May Note had an annual interest rate of 5% and a maturity date of May 15, 2022. All unpaid interest and principal are due and payable upon request of the Lender on or after the May Note’s maturity date.

In June 2020, the Company issued a promissory note, the SNAP June 2020 Note, to a Lender in exchange for $15,000 in cash proceeds. This note has an annual interest rate of 5% and a maturity date of June 26, 2022, if not converted earlier pursuant to conversion terms and change in control events as described below. All unpaid interest and principal are due and payable upon request of the Lender on or after the SNAP June 2020 Note’s maturity date.

The outstanding principal balance and unpaid accrued interest of the May Note and SNAP June 2020 Note are convertible pursuant to the following terms (“May Note Conversion Feature,” “SNAP June 2020 Note Conversion Feature,” collectively, “Conversion Features”): automatic conversion into equity shares in the next equity financing round (“May Note Qualified Financing,” “SNAP June 2020 Note Qualified Financing,” collectively, “Qualified Financing”) at a conversion price equal to either (a) the lowest cash price per share paid by investors in such qualified financing (which will reflect at least a 20% discount to the price per share paid by other investors purchasing securities in additional closings), or (b) if there are no additional closings, 0.80 times the price per share paid by investors purchasing equity securities in the Qualified Financing. The May Note Qualified Financing shall be at least $40,000, which includes the conversion of the May Note but excludes any other indebtedness. The SNAP June 2020 Note Qualified Financing shall be at least $30,000, which excludes the conversion of the SNAP June 2020 Note and any other indebtedness.

Furthermore, upon a change of control event, the Company shall settle both the May Note and SNAP June 2020 Note in cash, pursuant to the following terms (“Redemption Features”):

— 200% of the then outstanding principal amount of the respective note plus any unpaid accrued interest on the original principal of such note; and

— 100% of the then outstanding principal amount of the respective note plus any unpaid accrued interest on the original principal of such note, provided that if the change of control transaction closes between the Company and the Lender or an affiliate of the Lender.

The Company evaluated whether the Convertible Notes contain embedded features that meet the definition of derivatives under ASC 815, Derivatives and Hedging. The Conversion Features qualify as derivatives as they continuously reset as the underlying stock price increases or decreases so as to provide a variable number of shares for a fixed value of equity to the holders at any conversion date. As such, the Conversion Features were bifurcated and

accounted for as a derivative liability to be remeasured at the end of each reporting period. The Company recorded the bifurcated Conversion Features initially at fair value with the residual value being allocated to the Convertible Notes as a debt discount. The fair value of the Conversion Features upon issuance in May 2020 and June 2020, were $4,060 and $2,460, respectively, and were recorded as a derivative liability on the Company’s Consolidated Balance Sheet. The Redemption Features of the Convertible Notes do not meet the definition of derivatives. Therefore, the Redemption Features are not bifurcated.

The Company evaluated whether the Convertible Notes contain embedded features that meet the definition of derivatives under ASC 815, Derivatives and Hedging. The Company determined that certain conversion features met criteria to be bifurcated as derivative liabilities to be remeasured at the end of each reporting period. The Company recorded the bifurcated conversion features initially at fair value with the residual value being allocated to the convertible notes as a debt discount. The redemption features of the May Note and SNAP June 2020 Note do not meet the definition of derivatives. Therefore, the redemption features are not bifurcated.

The total amount of debt discount at issuance for the May Note and SNAP June 2020 Note was $4,175 and $2,529, respectively. The Company amortized the aggregate debt discount using the effective interest method. The Company recognized total interest expense of $2,015 associated with the SNAP June 2020 Note for the year ended December 31, 2021, out of which $1,265 relates to the amortization of the debt discount. The Company recognized total interest expense of $1,724 associated with the May Note and SNAP June 2020 Note for the year ended December 31, 2020, out of which $1,050 relates to the amortization of the debt discount. The debt discount related to the SNAP June 2020 Note is amortized over the life of the instrument, beginning at note issuance and ending on June 26, 2022, the date of maturity.

The May Note contains a conversion feature in which outstanding principal and any unpaid accrued interest automatically converts into equity securities. This conversion occurs when the Company issues and sells equity securities in a bona fide equity financing with total proceeds to the Company totaling more than $40,000, including the face value of the May Note before the May Note’s maturity date (“May Note Qualified Financing”). The SNAP June 2020 Note contains a similar conversion feature, differing where total proceeds must exceed $30,000, excluding the face value of the SNAP June 2020 Note (“SNAP June 2020 Note Qualified Financing”).

In August 2020, the Company issued Series D-3A Preferred Stock (“Series D-3A”) for proceeds in aggregate of approximately $40,300. The Series D-3A financing meets the definition of the May Note Qualified Financing. As a result, the May Note, with then outstanding principal balance of $25,000 and accrued unpaid interest of $288, were automatically converted into 766,293 shares of Series D-3A resulting in an extinguishment of the outstanding principal balance and accrued net of unamortized discount of $21,268, extinguishing the derivative liability at fair value of $5,360 at the acquisition price of Series D-3A of $30,652. In connection with the extinguishment, the Company recognized a loss of $3,775 on the consolidated statements of operations and comprehensive loss. The Series D-3A financing did not meet the definition of the SNAP June 2020 Note Qualified Financing and, as such, the SNAP June 2020 Note remained outstanding as of December 31, 2021, and December 31, 2020.

The following table summarizes the unamortized debt discount, fair value of conversion feature, and accrued interest as of December 31, 2021 and 2020, and fair value remeasurement for the years ended December 31, 2021 and 2020:

	December 31, 2021		December 31, 2020
Unamortized debt discount	$	657	$	1,942
Fair value of conversion feature	$	3,488	$	2,380
Accrued interest	$	1,136	$	395

				December 31, 2021				December 31, 2020
		Remeasurement of conversion feature – gain/(loss)		$	(1,108	)		$	80

Accrued interest is included in accrued liabilities as of December 31, 2021, and other non-current liabilities as of December 31, 2020, on the consolidated balance sheets to reflect the classification of the SNAP June 2020 Note as short-term in nature on December 31, 2021 and long-term in nature as of December 31, 2020. The Company recorded the remeasurement of derivative liabilities in other expense, net on the consolidated statements of operations and comprehensive loss.

SVB March 2021 Note

In March 2021, the Company entered into a loan and security agreement with a commercial bank to borrow $30,000 along with the issuance of warrants to purchase 127,570 shares of the Company’s common stock. The warrant’s allocated fair value was $2,316 at issuance. The SVB March 2021 Note also contains a final payment provision of $1,050. The warrants were recognized as a debt discount at issuance and recorded as a reduction of the debt balance under a relative fair value approach. The Company recorded the final payment as an increase to the principal balance and debt discount for the entire payment amount. The Company is amortizing the discounts on an effective interest basis over the period from issuance through the Early Maturity Date (as defined below).

The loan bears interest at an annual rate equal to the greater of 9% or 5.75% above the Prime Rate. As of December 31, 2021, the interest rate was 9%. Payments are interest-only for the first twelve months and are fully amortizable thereafter. The Company recorded interest expense in the consolidated statements of operations and comprehensive loss for the year ended December 31, 2021 of $4,508, of which $233 remained unpaid as accrued interest.

The term loan amortization date is April 1, 2022, with an opportunity for a six-month extension if certain performance milestones are met. The total amount of debt discount at issuance was $3,532. As of December 31, 2021, the unamortized debt discount totaled $1,086. The maturity date of the loan is April 26, 2022 (“Early Maturity Date”), with an opportunity for extension to September 2024 or March 2025 if certain performance milestones are met, including the conversion of the SNAP June 2020 Note. Accordingly, the Company has classified the entire note payable balance as short-term as of December 31, 2021.

SCI June 2021 Note

In June 2021, the Company entered into a loan and security agreement with a lender to obtain credit extensions to the Company. Extensions may be requested in $5,000 increments up to a total commitment amount of $15,000. The Company drew an initial $5,000 on June 14, 2021 and the remaining $10,000 on December 1, 2021. The SCI June 2021 Note also contains a final payment provision of 3.5% on each draw or $525 in total. Additionally, warrants were issued alongside the convertible note to purchase 63,785 shares of SoundHound’s common stock. The warrant’s allocated fair value was $1,527 at issuance. The Company recorded the final payment as an increase to the principal balance and debt discount for the entire payment amount upon each draw.

As the warrants and discounts of $2,150 are directly attributable to the total commitment of $15,000, the Company has presented its unamortized debt issuance cost associated with this convertible note as a current asset, recorded as debt issuance cost on the consolidated balance sheets. The Company is amortizing the cost on a straight-line basis from the issuance date through the early maturity date of June 26, 2022. The Company recorded $1,018 in interest expense related to the debt discounts during the year ended December 31, 2021. As of December 31, 2021, the unamortized debt discount totaled $1,132.

The loan bears interest at an annual rate equal to the greater of 9% or 5.75% above the Prime Rate. As of December 31, 2021, the interest rate is 9%. Payments are interest-only for the first twelve months and are fully amortizing thereafter. The Company incurred and paid $329 in stated interest in the consolidated statements of operations and comprehensive loss for the year ended December 31, 2021.

The loan amortization date is June 1, 2022, with an opportunity for a six-month extension if certain performance milestones are met. The maturity date of the loan is the earlier of May 2025 or when the SNAP June 2020 Note is either paid in full or matures on June 26, 2022. Upon mutual consent of the Company and its Agent, the outstanding principal amount of term loan advances may be converted into equity securities that are issued by SoundHound in an Initial Public Offering (“IPO”) or by a Special Purpose Acquisition Company (“SPAC”) during a private placement sale of SoundHound’s equity securities that closes substantially concurrently with the closing of a SPAC acquisition. If conversion occurs in connection with an IPO, the conversion of the principal amount shall be into the same class and series of equity securities for the initial price per security to the public sold in the IPO. If conversion occurs in connection with a SPAC, the conversion of principal amount shall be into the equity securities purchased by other investors in the SPAC at the same share price and upon the same terms. As of December 31, 2021, the Company has classified the SCI June 2021 Note as a current liability on its consolidated balance sheet.

The below table summarizes the Company’s debt balances as of December 31, 2021 and 2020:

Summary of Significant Accounting Policies

Note 3 — Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”).

Emerging Growth Company Status

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, (the “Securities Act”), as modified by the Jumpstart our Business Startups Act of 2012, (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of financial statement in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statement. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company has $235,295 of cash held outside of the Trust Account as of December 31, 2021 and no cash held outside of the Trust Account as of December 31, 2020. The Company did not have any cash equivalents as of December 31, 2021 and 2020.

Marketable Securities Held in Trust Account

At December 31, 2021, the Company had $133,010,583 in the Trust Account which may be utilized for Business Combination. As of December 31, 2021, the assets held in the Trust Account were invested in Treasury Securities consisting of money market funds.

Fair Value Measurements

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

• Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets;

• Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

• Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

The fair value of the Company’s certain assets and liabilities, which qualify as financial instruments under ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheet. The fair values of cash and cash equivalents, prepaid expenses, accounts payable and accrued expenses, and due to related party are estimated to approximate the carrying values as of December 31, 2021 due to the short maturities of such instruments.

The Company’s warrant liability and the fair value of its Representative Shares are based on valuation models utilizing management judgment and pricing inputs from observable and unobservable markets with less volume and transaction frequency than active markets. Significant deviations from these estimates and inputs could result in a material change in fair value. The fair value of the warrant liability and the fair value of its Representative Shares are classified as Level 3. See Note 7 for additional information on assets, liabilities and Representative Shares measured at fair value.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. At December 31, 2021 and 2020, the Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

Common Stock Subject to Possible Redemption

The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock feature certain redemption rights that is considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of the Company’s balance sheet.

Net Income (Loss) Per Common Share

The Company complies with accounting and disclosure requirements of FASB ASC 260, Earnings Per Share. The statements of operations include a presentation of income (loss) per redeemable Public Share and income (loss) per founder non-redeemable share following the two-class method of income (loss) per share. In order to determine the net income (loss) attributable to both the public redeemable shares and founder non-redeemable shares, the Company first considered the total income (loss) allocable to both sets of shares. This is calculated using the total net income (loss) less any dividends paid. For purposes of calculating net income (loss) per share, any remeasurement of the accretion to redemption value of the common stock subject to possible redemption was considered to be dividends

paid to the public stockholders. Subsequent to calculating the total income (loss) allocable to both sets of shares, the Company split the amount to be allocated using a ratio of 72.8% for the Public Shares and 27.2% for the founder non-redeemable shares for the year ended December 31, 2021, reflective of the respective participation rights.

The earnings per share presented in the statements of operations is based on the following:

	For the year ended December 31, 2021
Net loss	$	(981,884	)
Accretion of temporary equity to redemption value		(13,376,606	)
Net loss including accretion of temporary equity to redemption value	$	(14,358,490	)

	For the year ended December 31, 2021
	Redeemable			Non-redeemable
Basic and diluted net loss per share:
Numerator:
Allocation of net loss including accretion of temporary equity	$	(10,451,084	)	$	(3,907,406	)
Accretion of temporary equity to redemption value		13,376,606			—
Allocation of net income (loss)	$	2,925,522		$	(3,907,406	)

Denominator:
Weighted-average shares outstanding		10,589,315			3,959,088
Basic and diluted net income (loss) per share	$	0.28		$	(0.99	)

No shares of the Company were issued or outstanding in 2020 and, as a result, Earnings Per Share does not exist for 2020.

In connection with the underwriters’ partial exercise of their over-allotment option on March 19, 2021, 325,000 Founder Shares were no longer subject to forfeiture. These shares were excluded from the calculation of weighted average shares outstanding until they were no longer subject to forfeiture.

As of December 31, 2021, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common stock and then share in the Company’s earnings. As a result, diluted income (loss) per share is the same as basic income (loss) per share for the periods presented.

Offering Costs associated with the Initial Public Offering

The Company complies with the requirements of the ASC 340-10-S99-1 and SEC Staff Accounting Bulletin (“SAB”) Topic 5A - “Expenses of Offering”. Offering costs consist principally of professional and registration fees incurred through the balance sheet date that are related to the IPO and were charged to stockholders’ equity upon the completion of the IPO. Accordingly, as of March 15, 2021, offering costs in the aggregate of $4,849,810 have been charged to stockholders’ equity (consisting of $2,400,000 of underwriting discount and $2,449,810 of other offering costs).

On March 19, 2021, the underwriters partially exercised the over-allotment option to purchase 1,300,000 Public Units, generating an aggregate of gross proceeds of $13,000,000, and incurred additional transaction costs of $260,000 in underwriting discount.

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. Derivative instruments are recorded at fair value on the grant date and re-valued at each reporting date, with changes in the fair value reported in the statements of operations. Derivative assets and liabilities are classified on the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within 12 months of the balance sheet date. The Company has determined the warrants are a derivative instrument.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2021 and 2020, respectively. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations, cash flows and/or search for a target company, the specific impact is not readily determinable as of the date of the financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Recently Adopted Accounting Standards

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 (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity-linked contracts to qualify for scope exception, and it simplifies the diluted earnings per share calculation in certain areas. The Company adopted ASU 2020-06 on January 1, 2021. Adoption of the ASU did not impact the Company’s financial position, results of operations or cash flows.

Summary of Significant Accounting Policies

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Significant Accounting Policies

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding annual financial reporting. Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative U.S. GAAP included in the Accounting Standards Codification (“ASC”), and Accounting Standards Update (“ASU”) issued by the Financial Accounting Standards Board (“FASB”).

Principles of Consolidation

The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Reclassification

Certain prior period balances have been reclassified to conform to the current year presentation. Such changes include the presentation change on the consolidated statements of operations and comprehensive loss from a two-step presentation to a one-step presentation, as well as reclassifications or combinations of certain accounts on the consolidated balance sheets.

These reclassifications had no impact on total assets, total liabilities, net loss or comprehensive loss or accumulated deficit in the previously reported consolidated financial statements for the year ended December 31, 2020.

Foreign Currency

The functional currency of SoundHound, Inc. and its subsidiaries is the U.S. dollar. Foreign currency denominated transactions are converted into U.S. dollars at the average rates of exchange prevailing during the period. Assets and liabilities denominated in foreign currency are remeasured into U.S. dollars at current exchange rates at the balance sheet date for monetary assets and liabilities and at historical exchange rates for non-monetary assets and liabilities. During the years ended December 31, 2021 and 2020, the Company recognized net losses/(gains) related to foreign currency transactions and remeasurements of $501 and ($18), respectively, in the consolidated statements of operations as other expense, net.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported and disclosures in the consolidated financial statements and accompanying notes. Such estimates include revenue recognition, allowance for doubtful accounts, accrued liabilities, derivative and warrant liabilities, calculation of the incremental borrowing rate, financial instruments recorded at fair value on a recurring basis, valuation of deferred tax assets and uncertain tax positions and the fair value of common stock and other assumptions used to measure stock-based compensation expense. The Company bases its estimates on historical experience, the current economic environment, and on assumptions it believes are reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from changes in the economic environment will be reflected in the financial statements in future periods. Actual results could differ materially from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of 90 days or less from the date of purchase to be cash equivalents. The Company’s cash equivalents consist of mutual funds, commercial paper and certificates of deposit. The deposits exceed federally insured limits.

Restricted Cash Equivalents

The Company’s restricted cash equivalents were established according to the requirements under the leases for the Company’s corporate headquarters, data center and sales office, and are subject to certain restrictions under the leases. All amounts in restricted cash equivalents as of December 31, 2021 and 2020 represent funds held in certificates of deposit, have original maturities of six months to one year and are recorded at cost plus accrued interest, which approximates fair value as of December 31, 2021 and 2020. Restricted cash equivalents are classified as current or non-current on the consolidated balance sheets based on the remaining term of the restriction.

Accounts Receivable, Net

Accounts receivable consist of current trade receivables due from customers recorded at invoiced amounts, net of allowance for doubtful accounts. Accounts receivable do not bear interest and the Company generally does not require collateral or other security in support of accounts receivable.

The Company has established an allowance for doubtful accounts and evaluates the collectability of its accounts receivable based on known collection risks and historical experience. Uncollectible receivables are written off when all efforts to collect have been exhausted and recoveries are recognized when received. The allowance for doubtful accounts as of December 31, 2021 and December 31, 2020 was $109.

Property and Equipment, Net

Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is provided using the straight-line method over the estimated useful lives of the respective assets.

The estimated useful lives of the Company’s property and equipment are as follows:

		Computer equipment		3 – 4 years
		Software		3 years
		Furniture and fixtures		5 years
		Leasehold improvements		Lesser of useful life or the term of the lease

Maintenance and repairs that do not extend the life or improve the asset are expensed as incurred.

Impairment of Long-Lived Assets

The Company evaluates property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. An impairment loss is recognized when the total of estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition is less than its carrying amount. Impairment, if any, would be assessed using discounted cash flows or other appropriate measures of fair value. Through December 31, 2021, there have been no such impairments.

Segment Information

The Company has determined that the Chief Executive Officer is its chief operating decision maker. The Company’s Chief Executive Officer reviews financial information on a consolidated basis for purposes of allocating resources and evaluating financial performance. Accordingly, the Company has determined that it operates as a single reportable segment.

The Company’s property and equipment is primarily located in the United States. As of December 31, 2021, the Company’s property and equipment is located in the United States, except for 11.7% of assets located in Canada and 1.7% in other foreign jurisdictions. As of December 31, 2020, all property and equipment were located in the United States.

Emerging Growth Company Status

The Company is an emerging growth company (“EGC”) as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”) and may take advantage of reduced reporting requirements that are otherwise applicable to public companies. Section 107 of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with those standards. This means that when a standard is issued or revised and it has different application dates for public and nonpublic companies, the Company has the option to adopt the new or revised standard at the time nonpublic companies adopt the new or revised standard and can do so until such time that the Company either (i) irrevocably elects to “opt out” of such extended transition period or (ii) no longer qualifies as an emerging growth company. The Company has elected to use the extended transition period for complying with new or revised accounting standards unless the Company otherwise early adopts select standards.

Concentrations of Credit Risk and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to potential significant concentrations of credit risk consist principally of cash and cash equivalents. The Company regularly monitors its credit risk exposure and takes steps to mitigate the likelihood of these exposures resulting in actual loss.

As of December 31, 2021, accounts receivable balances due from five customers collectively totaled 86% of the Company’s consolidated accounts receivable balance. As of December 31, 2020, accounts receivable balances due from two customers collectively totaled 87% of the Company’s consolidated accounts receivable balance.

For the year ended December 31, 2021, the Company had three customers that accounted for 61% of revenue and two customers that accounted for 43% of revenue for the year ended December 31, 2020.

Equity Issuance Costs

The Company capitalizes certain legal, professional, accounting and other third-party fees that are directly associated with in-process equity financings, including the Business Combination, as deferred offering costs until such financings are consummated. After consummation of the financing, these costs are recorded as

a reduction of the proceeds received from the equity financing. If a planned equity financing is abandoned, the deferred offering costs are expensed immediately as a charge to operating expenses in the consolidated statements of operations and comprehensive loss.

Additionally, certain transaction costs incurred in connection with the pending merger agreement, which are direct and incremental to the proposed merger, will be deferred and recorded as a component of other non-current assets within the consolidated balance sheets and will offset cash proceeds from the Business Combination if successful. The Company had $1,264 of deferred offering costs recorded as of December 31, 2021. The Company had not incurred deferred offering costs as of December 31, 2020.

Revenue Recognition

The Company recognizes revenue under Accounting Standards Codification Topic 606 (“ASC 606”), Revenue from Contracts with Customers, when a customer obtains control of promised goods or services in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps:

(i) Identification of the contract(s) with a customer;

(ii) Identification of the performance obligations in the contract;

(iii) Determination of the transaction price, including the constraint on variable consideration;

(iv) Allocation of the transaction price to the performance obligations in the contract;

(v) Recognition of revenue when, or as, performance obligations are satisfied.

Contracts are accounted for when both parties have approved and committed to the contract, the rights of the parties and payment terms are identifiable, the contract has commercial substance and collectability of consideration is probable. Any payments received from customers that do not meet criteria for having a contract are recorded as deposit liabilities on the consolidated balance sheet.

Under ASC 606, assuming all other revenue recognition criteria have been met, the Company will recognize revenue for arrangements upon the transfer of control of the Company’s performance obligations to its customers. A performance obligation is a promise in a contract to transfer a distinct good or service to a customer and is the unit of account in ASC 606. Revenues are recognized when control of the promised goods or services are transferred to a customer in an amount that reflects the consideration that the Company expects to receive in exchange for those services. The Company currently generates its revenues through the following performance obligations: (1) hosted services, (2) professional services and (3) monetization.

Research and Development

The Company’s research and development costs are expensed as incurred. These costs include salaries and other personnel related expenses, contractor fees, facility costs, supplies, and depreciation of equipment associated with the design and development of new products prior to the establishment of their technological feasibility.

Warrants

The Company determines whether to classify contracts, such as warrants, that may be settled in its own stock as equity of the entity or as a liability. An equity-linked financial instrument must be considered indexed to the Company’s own stock to qualify for equity classification. The Company classifies warrants as liabilities for any contracts that may require a transfer of assets.

The warrants are considered freestanding instruments that qualify as liabilities under ASC Topic 480, Distinguishing Liabilities from Equity, as the Company is committed to issuing an instrument that ultimately may require a transfer of assets. The warrant liability is accounted for at fair value and remeasured at each reporting date. Accordingly, the Company classifies the warrants as a liability at their fair value and adjusts the instruments to fair value at each balance sheet date until the warrants are exercised or expired. Any change in the fair value of the warrants is recognized as other expense, net in the consolidated statements of operations and comprehensive loss.

Income Taxes

The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. A valuation allowance is established when, in management’s estimate, it is more-likely-than-not that the deferred tax asset will not be realized. The Company adopted a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. The Company records a liability for the difference between the benefit recognized and measured and the tax position taken or expected to be taken on the Company’s tax return.

The Company classifies interest and penalties related to uncertain tax positions in income tax expense, if applicable. There were no interest expenses or penalties related to unrecognized tax benefits recorded through the years ended December 31, 2021 and 2020.

Stock-Based Compensation

The Company measures and records the expense related to stock-based payment awards based on the fair value of those awards as determined on the date of grant. The Company recognizes stock-based compensation expense over the requisite service period of the individual grant, generally equal to the vesting period, and uses the straight-line method to recognize stock-based compensation. The Company uses the Black-Scholes-Merton (“Black- Scholes”) option-pricing model to determine the fair value of stock options. The Black-Scholes option-pricing model requires the use of highly subjective and complex assumptions to determine the fair value of stock options, including the option’s expected term and the price volatility of the underlying stock. The Company calculates the fair value of options granted by using the Black-Scholes option-pricing model with the following assumptions:

Expected Volatility — The Company estimates volatility for option grants by evaluating the average historical volatility of a peer group of companies for the period immediately preceding the option grant for a term that is approximately equal to the option’s expected term.

Expected Term — The expected term of the Company’s options represents the period that the stock-based awards are expected to be outstanding. The Company has elected to use the midpoint between the stock options’ vesting term and contractual expiration period to compute the expected term, as the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior.

Risk-Free Interest Rate — The risk-free interest rate is based on the implied yield currently available on U.S. Treasury zero-coupon issues with a term that is equal to the options’ expected term at the grant date.

Dividend Yield — The Company has not declared or paid dividends to date and does not anticipate declaring dividends. As such, the dividend yield has been estimated to be zero.

Fair Value Measurements

The Company defines fair value as the exchange price that would be received from an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The Company follows a three-level valuation hierarchy for disclosure of fair value measurements as follows:

• Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date.

• Level 2 — Inputs (other than quoted market prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

• Level 3 — Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

The Company’s derivative liabilities and warrants are measured at fair value on a recurring basis and are classified as Level 3 liabilities. The Company records subsequent adjustments to reflect the increase or decrease in estimated fair value at each reporting date on the consolidated statements of operations and comprehensive loss.

Redeemable Convertible Preferred Stock

The Company’s shares of redeemable convertible preferred stock (“Preferred Stock”) do not have a mandatory redemption date and are assessed at issuance for classification and redemption features requiring bifurcation. The Company presents as temporary equity any stock which (i) the Company undertakes to redeem at a fixed or determinable price on the fixed or determinable date or dates; (ii) is redeemable at the option of the holders, or (iii) has conditions for redemption which are not solely within the control of the Company. The Company’s Preferred Stock is redeemable upon a deemed liquidation event which the Company determined is not solely within its control and thus has classified shares of Preferred Stock as temporary equity until such time as the conditions are removed or lapse. Because the occurrence of a deemed liquidation event is not currently probable, the carrying values of the shares of Preferred Stock are not being accreted to their redemption values. Subsequent adjustments to the carrying values of the shares of Preferred Stock would be made only when a deemed liquidation event becomes probable.

Convertible Notes and Derivative Liabilities

The Company evaluates its convertible notes, and other contracts, if any, to determine if those contracts or embedded components of those contracts qualify as derivatives requiring bifurcation. The Company accounts for conversion features that meet the criteria for bifurcation as liabilities at fair value and adjusts the derivative instruments to fair value at each reporting period. The conversion features qualify as derivatives, as they continuously reset as the underlying stock price increases or decreases to provide a fixed value of equity to the holders at any conversion date. The conversion features are subject to remeasurement at each balance sheet date until exercised, and any change in fair value is recognized as a component of other expense, net in the consolidated statements of operations and comprehensive loss. The fair value of the conversion features has been estimated using a probability-weighted discount model with and without the conversion feature (see Note 9 for additional information).

The Company holds its convertible notes at amortized cost and amortizes the associated debt discount created from bifurcated derivatives and issuance costs under the effective interest or straight-line method until maturity or early conversion pursuant to the contractual terms of the arrangement.

Net Loss Per Share

Basic net loss per share attributable to common stockholders 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 share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common stock and potentially dilutive securities outstanding for the period. For purposes of the diluted net loss per share calculation, Preferred Stock, stock options, warrants and convertible notes are considered to be potentially dilutive securities. See Note 15 for further information.

Accordingly, in periods in which the Company reports a net loss, diluted net loss per share is the same as basic net loss per share, since dilutive common stock is not assumed to have been issued if their effect is anti-dilutive.

Recent Accounting Pronouncement — Adopted

From time to time, new accounting pronouncements, or Accounting Standards Updates, are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s financial position or results of operations upon adoption.

Leases

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (“Topic 842”) and subsequent amendments to the initial guidance: ASU 2017-13, ASU 2018-10, ASU 2018-11, ASU 2018-20 and ASU 2019-01 (collectively, “Topic 842”). Topic 842 aims to increase transparency and comparability among organizations by requiring lessees to recognize leases with a term greater than 12 months as a right-of-use (“ROU”) asset and corresponding lease liabilities on the balance sheet, regardless of lease classification, and requiring disclosure of key information about leasing arrangements. The lease liability should be initially measured at the present value of the remaining contractual lease payments. Subsequently, the ROU assets will be amortized generally on a straight-line basis over the lease term, and the lease liability will bear interest expense and be reduced for lease payments. Topic 842 is effective for the Company for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. A modified retrospective application is required with an option to not restate comparative periods in the period of adoption. The Company adopted Topic 842 on January 1, 2021 using the modified retrospective approach, and financial information for the comparative period was not updated.

In addition, the Company elected the transition package of three practical expedients which allow companies not to reassess (i) whether agreements contain leases, (ii) the classification of leases, and (iii) the capitalization of initial direct costs. Further, the Company elected to separate lease and non-lease components for the building asset class and elected to not separate lease and non-lease components for the equipment asset class. The Company also made an accounting policy election to recognize lease expense for leases with a term of 12 months or less on a straight-line basis over the lease term and recognize no ROU or lease liability for those leases.

The Company’s lease portfolio consists primarily of real estate assets and computer equipment. Some of these leases also require the Company to pay maintenance, utilities, taxes, insurance, and other operating expenses associated with the leased space. Based upon the nature of the items leased and the structure of the leases, the Company’s leases classified as operating leases continue to be classified as operating leases and capital leases will be accounted for as financing leases under the new accounting standard.

As a result of the adoption of the new lease accounting guidance, the Company recognized on January 1, 2021:

• Operating lease liabilities of approximately $11,428, which represent the present value of the remaining lease payments, as of the date of adoption, discounted using the Company’s incremental borrowing rate on a lease-by-lease basis, and

• Operating lease ROU assets of approximately $9,848 which represent the operating lease liabilities of $11,428, adjusted for (1) deferred rent of approximately $827, (2) lease incentives or tenant improvement allowance of $1,098 and (3) prepaid rent of $345.

• The Company additionally recharacterized its capital leases as finance leases. However, there was no quantitative impact to capital leases upon transitioning to the new standard.

The adoption of the new lease accounting standard did not have any other material impact on the Company’s consolidated balance sheet and did not impact the Company’s operating results and cash flows. See Leases in Note 13 for further information, including further discussion on the impact of adoption and changes in accounting policies relating to leases.

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 (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. ASU 2020-06 also removes certain settlement conditions that are required for equity-linked contracts to qualify for scope exception, and it simplifies the diluted earnings per share calculation in certain areas. The Company adopted ASU 2020-06 on January 1, 2021. Adoption of ASU 2020-06 did not impact the Company’s financial position, results of operations or cash flows as the Company does not have any instruments with cash or beneficial conversion features. Further, updates from ASU 2020-06 to Contracts in an Entity’s Own Equity does not impact the Company’s debt instruments as of December 31, 2021.

Recent Accounting Pronouncement — Not Yet Adopted

In October 2021, the FASB issued ASU 2021-08 Business Combinations (“ASC 805”) Accounting for Contract Assets and Contract Liabilities from Contracts with Customers guidance requiring entities to apply ASC 606 to recognize and measure contract assets and contract liabilities in a business combination. Under current U.S. GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers and other similar contracts that are accounted for in accordance with ASC 606, at fair value on the acquisition date. Under the new guidance the acquirer will recognize contract assets and contract liabilities at the same amounts recorded by the acquiree. The modifications improve comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of, and after a business combination. The amendment is effective for the Company in fiscal years beginning after December 15, 2023. Early adoption of the amendment is permitted. The Company anticipates that it will not have a material impact on its consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13 to update the methodology used to measure current expected credit losses (“CECL”). This ASU applies to financial assets measured at amortized cost, including loans, held-to-maturity debt securities, net investments in leases, and trade accounts receivable as well as certain off-balance sheet credit exposures, such as loan commitments. This ASU replaces the current incurred loss impairment methodology with a methodology to reflect CECL and requires consideration of a broader range of reasonable and supportable information to explain credit loss estimates. The guidance must be adopted using a modified retrospective transition method through a cumulative-effect adjustment to retained earnings/(deficit) in the period of adoption. In November 2019, the FASB issued ASU 2019-10, Financial Instruments — Credit Losses (“Topic 326”), Targeted Transition Relief, which amends the transition guidance for ASU 2016-13. The ASU provides entities with the option to irrevocably elect the fair value option in Subtopic 825-10 on

an instrument-by-instrument basis. ASU 2019-10 and ASU 2016-13 are effective for years beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact the standard will have on the Company’s consolidated financial statements.

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (“Topic 740”) (“ASU 2019-12”). ASU 2019-12 eliminates the need for an organization to analyze whether the following apply in a given period (1) exception to the incremental approach for intra-period tax allocation (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments and (3) exceptions in interim period income tax accounting for year-to-date losses that exceed anticipated losses. ASU 2019-12 also is designed to improve financial statement preparers’ application of income tax-related guidance and simplify U.S. GAAP for (1) franchise taxes that are partially based on income, (2) transactions with a government that result in a step-up in the tax basis of goodwill, (3) separate financial statements of legal entities that are not subject to tax, and (4) enacted changes in tax laws in interim periods. The amendments in ASU 2019-12 are effective for the Company in fiscal years beginning after December 15, 2021. Early adoption of the amendments is permitted. An entity that elects early adoption must adopt all the amendments in the same period. Adoption of ASU 2019-12 is not expected to result in any material changes to the way the tax provision is prepared and is not expected to have a material impact on the Company’s consolidated financial statements.

Stock Incentive Plan [Line Items]

STOCK INCENTIVE PLAN

12. STOCK INCENTIVE PLAN

The Board of Directors has authorized and in April 2016 adopted the 2016 Equity Incentive Plan (the “2016 Plan”) as a successor and continuation of the 2006 Plan (collectively, the “Plans”). Under the Plans, the Board of Directors may grant awards of options and restricted stock, as well as stock appreciation rights and other stock awards. During the year ended December 31, 2021, the Company amended the 2016 Plan to increase the number of shares of common stock reserved for issuance under the Plans by 1,200,000 to an aggregate of 8,701,460.

The 2016 Plan provides for incentive stock options to be granted to employees at an exercise price not less than 100% of the fair value at the grant date as determined by the Board of Directors, unless the optionee is a 10% stockholder, in which case the option price will not be less than 110% of such fair market value. Options granted generally have a maximum term of 10 years from grant date, are exercisable upon vesting unless otherwise designated for early exercise by the Board of Directors at the time of grant, and generally vest over a four-year period, with a 25% cliff vesting after one year and then ratably on a monthly basis for the remaining three years.

Option Activity

Stock option activity under the Plans is as follows for the years ended December 31, 2021 and 2020:

	Shares Available for Grant		Outstanding Stock Options		Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Term (Years)	Average Intrinsic Value
Outstanding, January 1, 2020	378,010		4,276,480		$	10.35	6.44	$	33,785

Options exercisable as of December 31, 2021			3,322,160			12.23	5.32		125,517

Options exercised early are subject to the vesting provisions mentioned above, and any unvested shares are subject to repurchase at the original price upon termination of employment, death, or disability. There were no option exercises during the year ended December 31, 2021 and 2020 that were subject to repurchase.

The total fair value of options vested was approximately $5,358 and $5,400, during the years ended December 31, 2021 and 2020, respectively.

The following table summarizes information with respect to stock options outstanding and exercisable as of December 31, 2021:

	Options Outstanding		Options Exercisable
Range of Exercise Prices Per Share	Shares Outstanding	Weighted Average Remaining Contractual Life (Years)	Shares Outstanding	Weighted Average Remaining Contractual Life (Years)

	5,475,283	6.78	3,322,160	5.32

During the years ended December 31, 2021 and 2020, the Company’s stock compensation expense was $6,322 and $5,897, respectively. As of December 31, 2021, the unamortized expense related to outstanding awards was $25,572. The weighted average remaining amortization period over which the balance as of December 31, 2021 is to be amortized is 3.12 years. No income tax benefit was recognized for this compensation expense in the Consolidated Statement of Operations and Comprehensive Loss, as the Company does not anticipate realizing any such benefit in the future.

Employee Stock-Based Compensation

For the purpose of determining the estimated fair value of share-based payment awards issued in the form of stock options, the Company uses the Black-Scholes option-pricing model as permitted under the provisions for share-based payment awards.

The assumptions under the Black-Scholes option-pricing model and the weighted average calculated fair value of the options granted to employees as of December 31, 2021 and 2020 are as follows:

	December 31, 2021			December 31, 2020
Fair value of common stock	$	40.83		$	20.37
Dividend yield		0	%		0	%
Expected volatility		42	%		44	%
Expected term (years)		6.01			5.92
Risk free interest rate		1.14	%		0.64	%

Stock-based compensation is classified in the following operating expense accounts on the consolidated statements of operations and comprehensive loss for the years ended December 31, 2021 and 2020:

	December 31, 2021		December 31, 2020
Research and development	$	4,434	$	3,605
Sales and marketing		509		414
General and administrative		1,379		1,878
Total	$	6,322	$	5,897

Executive Options

The Company historically issued option awards to key personnel with contractual expirations of 5 to 10 years. Certain individuals had not exercised their options prior to expiration. As a result of the expiration of unexercised but fully vested options awards, the Company issued new options for the same quantity previously granted, but with an exercise price set to the then fair value of common stock determined in accordance with a board approved 409A.

Furthermore, in an effort to make the holders whole, the Company entered into a change in control bonus Letter Agreement with each individual. Pursuant to the agreement, each individual is entitled to an additional lump sum payment capped at the difference between the original aggregate exercise price and the new aggregate exercise price upon a change in control transaction as defined in the Company’s 2016 Equity Incentive Plan, provided that such a transaction also constitutes a “Liquidation Transaction” as defined in the Company’s Certificate of Incorporation.

The maximum change in control bonus for executive award holders is $5,837 and remains unamortized as of December 31, 2021.

Warrants [Line Items]
WARRANTS	7. WARRANTS In connection with the issuance of promissory notes in September 2010 and March 2011, the Company issued detachable warrants to purchase 76,180 and 25,394 shares of Series B Preferred Stock (“Series B Warrants”), respectively, at $1.97 per share to the lenders, which were immediately exercisable. The warrants have a ten-year expiration date from the applicable closing date of September 2020 and March 2021. The remaining warrants were exercised during the year ended December 31, 2020 and, therefore, were no longer outstanding as of December 31, 2020. In connection with the issuance of the April 2013 Note and November 2013 Note, the Company issued detachable warrants to purchase 44,708 and 89,418 shares of Series C Preferred Stock (“Series C Warrants”), respectively, at $6.71 per share to the lenders, which were immediately exercisable. In December 2021, all outstanding 134,126 shares of warrants related to April 2013 Note and November 2013 were net exercised, leading to a net issuance of 116,150 shares of Series C Preferred Stock. This resulted into $3,812 recorded as other expense, net within the consolidated statements of operations and comprehensive loss for the change in the fair value of the warrant liability immediately before exercise. As of December 31, 2021 and 2020, the fair value of the warrant liability was $0 and $2,004, respectively. In connection with the issuance of the Company’s 2021 note payable (“SVB March 2021 Note”) and 2021 Convertible Note (“SCI June 2021 Note”), the Company issued detachable warrants to purchase 127,570 and 63,785 shares of common stock, respectively, with an exercise price of $20.37 per share to the lenders, which were immediately exercisable. The Company recorded the warrants initially at fair value (see Note 9 for additional information) as paid-in-capital on the consolidated balance sheets based on the allocation of its relative fair value of the debt proceeds. See Note 9 for additional information on the fair value calculation. The fair value in relation to the SVB March 2021 Note was allocated to the notes as a discount. The fair value in relation to the SCI June 2021 Note was capitalized as an asset, as the underlying debt bears similarity to a revolving commitment. As the warrants were classified as equity, they are not subject to remeasurement at the end of each reporting period. The initial allocated fair value of the warrants as of March 31, 2021 and June 14, 2021 was $2,316 and $1,527, respectively. The warrants have a ten-year expiration date from the applicable closing date of March 2031 and June 2031, respectively.

The Company’s consolidated financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has reviewed the relevant conditions and events surrounding its ability to continue as a going concern including among others: historical losses, projected future results, including the effects of COVID-19, cash requirements for the upcoming year, funding capacity, net working capital, total stockholders’ deficit and future access to capital. On November 15, 2021, the Company entered into a definitive merger agreement with Archimedes Tech SPAC Partners Co. (the “Business Combination” or the “Merger”). The transaction is expected to deliver between $111,000 and $244,000 of gross proceeds with an expected closing date during the second quarter of 2022. Management believes the Company’s sources of liquidity will be sufficient to fund the Company’s planned operations and existing obligations within one year after the date that the consolidated financial statements are issued. In the event that the Company does not achieve profitability and financing objectives in its current operating plan, management has the ability and commitment to reduce operating expenses as necessary. The Company’s long-term success is dependent upon its ability to successfully raise additional capital, market its existing services, increase revenues, and, ultimately, to achieve profitable operations. The consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. Other Risk and Uncertainties During the two-year period ended December 31, 2021, and subsequently afterward, the Company continued to experience the results of the worldwide COVID-19 pandemic. The COVID-19 outbreak in the United States has caused business disruption through mandated and voluntary closings of businesses and shelter in place orders. In response, the U.S. Government enacted the CARES Act, which includes significant provisions to provide relief and assistance to affected organizations. While the disruption is currently expected to be temporary, there is considerable uncertainty around potential future closings, shelter in place orders, containment of the recent COVID-19 variants, and the ultimate impact of the CARES Act and other government initiatives. The COVID-19 pandemic and its resulting economic and other effects could result in significant adverse effects on our customers’ cash flow and their ability to manufacture, distribute, and sell products incorporating our voice-enabling technologies. This in turn may cause customers to be less able to pay invoices for royalties, licensing fees and usage fees, or may result in a reduction in the royalties, licensing fees and usage fees that the Company earns which are often based on the number of units sold or distributed by customers. This reduction could cause adverse effects on the business, results of operations, financial condition, cash flows and ability to raise operating capital. In addition, any depression or recession resulting from the COVID-19 pandemic may adversely change consumer behavior and demand, including products sold by customers, which may result in a significant reduction in our revenue, results of operations and financial condition. To date, this matter has not negatively impacted the Company. However, the financial impact and duration cannot be reasonably estimated at this time.

Common stock, subject to possible redemption	13,300,000
Description of warrant	Each whole warrant entitles the holder to purchase one common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of an initial Business Combination. The warrants will expire on the fifth anniversary of the completion of an initial Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.However, no warrants will be exercisable for cash unless the Company has an effective and current registration statement covering the shares of common stock issuable upon exercise of the warrants and a current prospectus relating to such shares of common stock. Notwithstanding the foregoing, if a registration statement covering the shares of common stock issuable upon exercise of the Public Warrants is not effective within 90 days following the consummation of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis. In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value”(defined below) by (y) the fair market value. The “fair market value” for this purpose will mean the average reported last sale price of the shares of common stock for the 5 trading days ending on the trading day prior to the date of exercise.
Warrant redemption, description	The Company may call the warrants for redemption (excluding the Private Warrants and any warrants underlying additional units issued to the Sponsor, initial stockholders, officers, directors or their affiliates in payment of Working Capital Loans made to the Company), in whole and not in part, at a price of $0.01 per warrant,• at any time after the warrants become exercisable,• upon not less than 30 days’ prior written notice of redemption to each warrant holder,• If, and only if, the reported last sale price of the shares of common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations), for any 20 trading days within a 30 trading day period commencing after the warrants become exercisable and ending on the third business day prior to the notice of redemption to warrant holders; and• if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants.In addition, if (x) the Company issues additional shares of common stock or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors, and in the case of any such issuance to the Sponsor, initial stockholders or their affiliates, without taking into account any Founder Shares held by them prior to such issuance), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (z) the Market Value is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the greater of (i) the Market Value or (ii) the price at which the Company issues the additional shares of common stock or equity-linked securities, and the $18.00 redemption trigger price will be adjusted to 180% of this amount.

Restatement of Prior Period Financial Statements

Note 2 — Restatement of Prior Period Financial Statements

Redeemable Equity Instruments

As a result of recent guidance to Special Purpose Acquisition Companies by the Securities and Exchange Commission (the “SEC”) regarding redeemable equity instruments, the Company revisited its application of ASC 480-10-S99 on the Company’s financial statements. The Company had previously classified a portion of its Public Subunits (and the underlying shares of common stock) in permanent equity. Subsequent to the re-evaluation, the Company’s management concluded that all of its Public Subunits should be classified as temporary equity. The identified errors impacted the Company’s Form 8-K filing on March 19, 2021 containing the IPO balance sheet as of March 15, 2021 (the “Closing Form 8-K), Form 10-Q filing on July 27, 2021 containing financial statements as of March 31, 2021, Form 10-Q filing on August 27, 2021 containing financial statements as of June 30, 2021, and Form 10-Q filing on November 15, 2021 containing financial statements as of September 30, 2021 (collectively, the “Prior Period Financial Statements”). In accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” and SEC Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements;” the Company evaluated the errors and has determined that the related impacts were material to the Prior Period Financial Statements. Accordingly, the Company has corrected such material errors by restating its Prior Period Financial Statements and classified all Public Subunits as temporary. The Company will also correct previously reported financial information for such material errors in future filings, as applicable.

Classification of Private Warrants & Fair Value of Representative Shares

On April 12, 2021, the Staff of the SEC issued a statement entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies.” In the statement, the SEC Staff, among other things, highlighted potential accounting implications of certain terms that are common in warrants issued in connection with the initial public offerings of special purpose acquisition companies such as the Company. As a result of the Staff statement and in light of evolving views as to certain provisions commonly included in warrants issued by special purpose acquisition companies, the Company re-evaluated the accounting for its Public Warrants and Private Warrants under ASC 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity, and concluded that the Private Warrants do not meet the criteria to be classified in stockholders’ equity, since the Private Warrants meet the definition of a derivative under ASC 815-40. Additionally, the Company’s management re-evaluated the fair value of the Representative Shares and concluded that the fair value the Company had previously used for the Representative Shares were incorrect and needs to be restated. The identified errors impacted the Prior Period Financial Statements. In accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” and SEC Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements,” the Company evaluated the errors and has determined that the related impacts were qualitatively immaterial to the Prior Period Financial Statements but, in consideration that the Company is restating its Prior Period Financial Statements to address the misclassification of redeemable equity instruments, the Company concluded that it should restate the identified errors related to the classification of Private Warrants and the fair value of Representative Shares as well.

In August 2020, the Company issued 454,545 shares of Series D-3A Preferred Stock at $33.00 per share for net cash proceeds of $15,000. Collectively, with the conversion of the May Note, the Company received total proceeds of approximately $40,300. This issuance met the condition of the May Note Qualified Financing. As a result, the May Note converted into 766,293 shares of Series D-3A Preferred Stock (Note 8).

In September 2020, the Company entered into a stock exchange agreement (“Exchange Agreement”) with the holders of Series D-3A Preferred Stock (the “D-3A Investors”) pursuant to which the D-3A investors exchanged all 1,220,838 shares of Series D-3A Preferred Stock for an equivalent number of shares of Series D-3 Preferred Stock. In connection with the Exchange Agreement, due to the difference in the fair value of Series D-3A and Series D-3 Preferred Stock, the Company recognized a deemed dividend of $3,182 during the year ended December 31, 2020.

In November 2020, the Company issued 25,000 shares of Series D-3 Preferred Stock for net cash proceeds of approximately $1,000.

In November 2020, the Series B Warrants were exercised in full resulting in the issuance of 101,574 shares of Series B Preferred Stock at $1.97 per share for net cash proceeds of approximately $200.

In December 2021, all outstanding 134,126 shares of Series C Warrants issued with April 2013 Note and November 2013 Note were net share settled, resulting in the issuance of 116,150 Series C Preferred Stock. Refer to Note 7 — Warrants for additional detail. As a result of the exercise, $5,816 was recorded in Preferred Stock.

The holders of the Company’s Series A, Series B, Series C, Series C-1, Series D, Series D-1, Series D-2, Series D-3 and Series D-3A Preferred Stock (collectively, “Preferred Stock”) have the following rights, preferences and privileges:

Dividends

The holders of shares of Series A, Series B, Series C, Series C-1, Series D, Series D-1, Series D-3 and Series D-3A Preferred Stock are entitled to receive dividends (“Senior Preferred Dividends”), on a pari passu basis, prior and in preference to any declaration or payment of any dividend on the common stock of the Company, at the rate of $0.11824, $0.15752, $0.5368, $1.6104, $2.08504, $2.64, $3.20 and $2.64 per share, respectively, per annum, on each outstanding share, adjusted for certain events, such as stock splits, stock dividends, reclassification and the like, payable quarterly when, as and if declared by the Board of Directors (“Board”) of the Company.

After the payment or setting aside of payment of the Senior Preferred Dividends, the holders of shares of Series D-2 Preferred Stock are entitled to receive dividends (“Junior Preferred Dividends”), prior and in preference to any declaration or payment of any dividend (other than dividends on common stock payable in common stock) on the common stock of the Company, at the rate of $2.64 per share, per annum, on each outstanding share, adjusted for certain events, such as stock splits, stock dividends, reclassification and the like, payable quarterly when, as and if declared by the Board. Such dividends shall not be cumulative.

After the payment or setting aside for payment of the Senior Preferred Dividends and the Junior Preferred Dividends, any additional dividends declared or paid in any fiscal year shall be distributed among the holders of Preferred Stock and common stock then outstanding pro rata based on the number of shares of common stock then held by each holder (assuming conversion of all such Preferred Stock into common stock at the then-effective conversion price as defined in the amended and restated certificate of incorporation). No dividends have been declared during the years ended December 31, 2021, and December 31, 2020.

Upon the completion of the liquidation preferences above, the remaining assets of the Company available for distribution to stockholders will be distributed among the holders of the Preferred Stock and the common stock pro rata based on the number of shares of common stock held by each (assuming conversion of all such Preferred Stock into common stock ) until the holders of Series D-3, Series D-1, Series D-2, Series D-3A, Series D, Series C-1, Series C, Series B and Series A Preferred Stock have received an aggregate of $40.00, $33.00, $33.00, $33.00, $26.063, $20.13, $6.71, $4.922 and $3.695 per share, respectively, adjustable for certain events, such as stock splits, stock dividends, reclassification and the like, for each share of respective Series of Preferred

Stock then held by them (including amounts paid pursuant to the liquidation preferences above). Thereafter, the holders of the common stock will receive all of the remaining assets of the Company pro rata based on the number of shares of common stock held by each.

Note 7 — Fair Value Measurements

Non-Recurring Fair Value Measurement

The following table presents information about the Company’s Representative Shares that were measured at fair value on a non-recurring basis as of January 13, 2021 and indicates the fair value hierarchy of the valuation techniques the Company utilized to determine such fair value.

	January 13, 2021		Quoted Prices In Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Other Unobservable Inputs (Level 3)
Stockholders’ Equity:
Representative Shares	$	2,024,463	$	—	$	—	$	2,024,463
	$	2,024,463	$	—	$	—	$	2,024,463

The estimated fair value of the Representative Shares on January 13, 2021, the date the Representative Shares were issued, was determined using Level 3 inputs. Inherent in a Monte-Carlo simulation model utilizing the probability weighted expected return method are assumptions related to the expected stock-price volatility (pre-merger), the risk-free interest rate, and the expected restricted term. The Company estimates the volatility of its common stock based on management’s understanding of the volatility associated with instruments of other similar entities. The risk-free interest rate is based on the U.S. Treasury Constant Maturity similar to the expected restricted term of the Representative Shares. The expected restricted term of the Representative Shares is simulated based on management assumptions regarding the timing and likelihood of completing the IPO and a business combination. The dividend rate is based on the historical rate, which the Company anticipates to remain at zero. The assumptions used in calculating the estimated fair values represent the Company’s best estimate. However, inherent uncertainties are involved. If factors or assumptions change, the estimated fair values could be materially different.

The key inputs into the Monte Carlo simulation model for the Representative Shares were as follows at January 13, 2021:

Input	January 13, 2021
Restricted term (years)		1.11
Expected volatility		12.5	%
Risk-free interest rate		0.12	%
Stock price	$	9.37
Dividend yield		0	%

Recurring Fair Value Measurement

The following table presents information about the Company’s assets and liabilities that were measured at fair value on a recurring basis as of December 31, 2021 and indicates the fair value hierarchy of the valuation techniques the Company utilized to determine such fair value.

	December 31, 2021		Quoted Prices In Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Other Unobservable Inputs (Level 3)
Assets:
U.S. Mutual Fund held in Trust Account	$	133,010,583	$	133,010,583	$	—	$	—

Warrant Liability	$	247,514	$	—	$	—	$	247,514
	$	247,514	$	—	$	—	$	247,514

The estimated fair value of the warrant liability on March 15, 2021 and December 31, 2021 is determined using Level 3 inputs. Inherent in a Monte-Carlo simulation model are assumptions related to expected stock-price volatility (pre-merger and post-merger), expected term, dividend yield and risk-free interest rate. The Company estimates the volatility of its common stock based on management’s understanding of the volatility associated with instruments of other similar entities. The risk-free interest rate is based on the U.S. Treasury Constant Maturity similar to the expected remaining life of the warrants. The expected life of the warrants is simulated based on management assumptions regarding the timing and likelihood of completing a business combination. The dividend rate is based on the historical rate, which the Company anticipates to remain at zero. The assumptions used in calculating the estimated fair values represent the Company’s best estimate. However, inherent uncertainties are involved. If factors or assumptions change, the estimated fair values could be materially different.

The key inputs into the Monte Carlo simulation model for the warrant liability were as follows at March 15, 2021:

Input	March 15, 2021
Expected term (years)		5.99
Expected volatility		24.3	%
Risk-free interest rate		1.06	%
Stock price	$	9.36
Dividend yield		0	%
Exercise price	$	11.5

The key inputs into the Monte Carlo simulation model for the warrant liability were as follows at December 31, 2021:

Input	December 31, 2021
Expected term (years)		5.30
Expected volatility		19.5	%
Risk-free interest rate		1.29	%
Stock price	$	9.58
Dividend yield		0	%
Exercise price	$	11.5

The following table sets forth a summary of the changes in the fair value of the warrant liability for the year ended December 31, 2021:

	Warrant Liability
Fair value as of December 31, 2020	$	—
Initial fair value of warrant liability upon issuance at IPO		270,307

	Fair Value Measurements as of December 31, 2021

Liabilities:
Derivative liability		—		—		(2,380	)
Warrant liability		—		—		(2,004	)
Total	$	35,856	$	—	$	(4,384	)

The fair values of the warrants were determined based on significant inputs not observable in the market, which represent Level 3 measurements within the fair value hierarchy.

In order to determine the fair value of the warrants, the Company utilized a Black-Scholes option-pricing model. Estimates and assumptions impacting the fair value measurement include the fair value of the underlying shares, the remaining contractual or expected term of the warrants, risk-free interest rate, expected dividend yield and expected volatility of the price of the underlying stock on an as-converted basis.

The Company considered the probability of a deemed liquidation event in determining the remaining expected term of the warrants, which was used as an input to the model. The Company lacks Company-specific historical and implied volatility information of its stock since there is currently no market. Therefore, it estimated its expected stock volatility based on the historical volatility of publicly traded guideline companies for a term equal to the remaining contractual or expected term of the warrants. The risk-free interest rate was determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the remaining contractual or expected term of the warrants. The Company estimated no expected dividend yield based on the fact that the Company has never paid or declared dividends and does not intend to do so in the foreseeable future.

Series B Warrants (September 2010 and March 2011)

The Company revalued its Series B Warrants as of its exercise date in November 2020, resulting in an increase in fair value of approximately $269, which was recorded as a component of other expense, net, in the accompanying consolidated statements of operations and comprehensive loss, with a corresponding increase to the warrant liability on the consolidated balance sheets.

The Company determined the fair value per share of the underlying Series B Preferred Stock by taking into consideration the most recent sales of its Preferred Stock, results obtained from third party valuations and additional factors that are deemed relevant. As a private company, specific historical and implied volatility information of its stock is not available. Therefore, the Company estimates its expected stock price volatility based on the historical volatility of publicly traded peer companies for a term equal to the expected term of

the Series B Warrants. This risk-free interest rate is determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the expected term of the Series B Warrants. The Company estimated a 0% expected dividend yield based on the fact that the Company has never paid or declared dividends and does not intend to do so in the foreseeable future. In November 2020, the Series B Warrants were exercised in full resulting in the issuance of 101,574 Series B Preferred Stock at $1.97 per share in exchange for $200 and a decrease in the corresponding warrant liability of $1,931 representing its intrinsic value on the date of exercise. Therefore, the warrants were not subsequently revalued as of December 31, 2021 or 2020.

Series C Warrants (April 2013 and November 2013)

The Company revalued its Series C Warrants as of December 31, 2020 resulting in an increase in fair value of approximately $318, which was recorded as a component of other expense, net, in the accompanying consolidated statements of operations and comprehensive loss, with a corresponding increase to the warrant liability on the consolidated balance sheet.

In December 2021, Series C Warrants were fully exercised. Immediately prior to their exercise, the Company revalued the warrants to their intrinsic value, resulting in a change in fair value of $3,812. This change in fair value was recorded as a component of other expense, net, in the accompanying consolidated statements of operations and comprehensive loss. The warrants were recorded as Series C Preferred Stock at their fair value of $5,816 upon net share settlement.

The aggregate fair value of the Series C Warrants as of December 31, 2021 and 2020 was approximately $0 and $2,004, respectively.

The Company determined the fair value of the April 2013 Series C Warrants using the Black-Scholes option-pricing model using the following assumptions:

	December 31, 2020
Expected dividend rate	0	%
Risk-free interest rate	0.14	%
Expected volatility	48	%
Expected term (in years)	2.16

The Company determined the fair value of the November 2013 Series C Warrants using the Black-Scholes option-pricing model and the following assumptions:

	December 31, 2020
Expected dividend rate	0	%
Risk-free interest rate	0.16	%
Expected volatility	47	%
Expected term (in years)	2.87

Common Stock Warrants (SVB March 2021 Note and SCI June 2021 Note)

The Company issued common stock warrants in connection with the SVB March 2021 Note and SCI June 2021 Note (See Note 8 for additional information). The SVB March 2021 Note and SCI June 2021 Note warrants were recorded based on the allocation of its relative fair of the debt proceeds of $2,316 and $1,527, respectively. The warrants were classified as equity instruments at inception with a corresponding discount recorded at issuance

against the outstanding notes in connection with the SVB March 2021 Note or as an asset in connection with the SCI June 2021 Note. The common stock warrants are not subject to remeasurement at each subsequent balance sheet date due to their classification as equity instruments as they are considered indexed to the Company’s stock. As of December 31, 2021, none of these warrants have been exercised. The SVB March 2021 Note warrants expire in March 2031 and the SCI June 2021 Note warrants expire in June 2031.

The Company determined the fair value of the SVB March 2021 Note and SCI June 2021 Note common stock warrants at issuance using the Black-Scholes option-pricing model using the following assumptions, respectively:

SVB March 2021 Note Common Stock Warrants
Expected dividend rate	0	%
Risk-free interest rate	1.74	%
Expected volatility	47	%
Expected term (in years)	10.00

SCI June 2021 Note Common Stock Warrants
Expected dividend rate	0	%
Risk-free interest rate	1.51	%
Expected volatility	47	%
Expected term (in years)	10.00

Derivative Liability (SNAP June 2020 Note)

To determine the fair value of the embedded derivative associated with the SNAP June 2020 Note, the Company utilized the income approach model using the With and Without method. Using the With and Without method, the Company modeled expected cash flows to the noteholder under Next Equity Financing, Change in Control, SPAC/Private Investment in Public Equity, and IPO scenarios. The value of the Embedded Derivatives was determined as the differential value from the perspective of the With and Without Method. The Company utilized the following assumptions at the valuation date:

	December 31, 2021		December 31, 2020
Probability of Next Equity Financing	3	%	65	%
Probability of SPAC/PIPE	95	%	33	%
Probability of IPO	2	%	2	%
	100	%	100	%
Weighted average term (years)	0.27		0.26
Weighted average discount rate	25.00	%	8.63	%

The significant unobservable inputs used in the fair value measurement of the derivative liability are the remaining expected term, the discount rate, and the probability of financing for each scenario. Significant increases (decreases) in the term would result in significantly lower (higher) fair value measurements. Significant increases (decreases) in the discount rate would result in significantly lower (higher) fair value measurements.

The following table sets forth a summary of changes in fair value of the Company’s derivative liability and warrant liability for which fair value was determined by Level 3 inputs:

	Derivative Liability			Warrant Liability
Balance as of January 1, 2020	$	—		$	3,348
Initial fair value of derivative liability		6,481			—
Extinguishment of derivative liability		(5,360	)		—
Exercise of warrants		—			(1,931	)
Change in fair value		1,259			587

Change in fair value		1,108			3,812
Exercise of warrants		—			(5,816	)
Balance as of December 31, 2021	$	3,488		$	—

There were no transfers of financial instruments between the three levels of the fair value hierarchy for the years ended December 31, 2021 and 2020. The Company had no other financial assets or liabilities that were required to be measured at fair value on a recurring basis.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

As of December 31, 2021, the Company has $366,866 of U.S. federal net operating loss carryovers, which do not expire, and no state net operating loss carryovers available to offset future taxable income.

In assessing the realization of the deferred tax assets, management considers whether it is more likely than not that some portion of all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the year ended December 31, 2021, the change in the valuation allowance was $210,982.

A reconciliation of the federal income tax rate to the Company’s effective tax rate at December 31, 2021 is as follows:

Statutory federal income tax rate	21.00	%
State taxes, net of federal tax benefit	0.00	%
Permanent Book/Tax Differences	0.49	%
Change in valuation allowance	(21.49	)%
Income tax provision	—	%

The Company files income tax returns in the U.S. federal jurisdiction in various state and local jurisdictions and is subject to examination by the various taxing authorities.

The Company has incurred net pre-tax losses in the United States only for all periods presented. The Company recorded an income tax expense of $456 and $738 for the years ended December 31, 2021 and 2020, which reflects withholding tax paid on the U.S. books for sales in Korea and estimated 2021 income tax related to foreign subsidiaries.

The benefit from income taxes differs from the amount expected by applying the federal statutory rate to the loss before taxes as follows:

	2021		2020
Federal statutory income tax rate	21.00	%	21.00	%
State income tax rate, net of federal benefit	2.56	%	1.63	%
Foreign withholding and income tax	-0.49	%	-0.99	%

Non-deductible permanent expenses	-1.26	%	-4.61	%
Other	-0.95	%	-0.09	%
	-0.58	%	-0.99	%

Deferred income tax reflects the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The categories that give rise to significant components of the deferred tax assets are as follows:

	2021			2020
Deferred tax assets:
Net operating loss carryforwards	$	70,808		$	54,527
Research and development credits		10,650			9,035

Right-of-use assets		(2,461	)		—
Gross deferred tax liabilities		(2,461	)		(78	)
Net deferred tax assets	$	2,168		$	2,282

Based on available objective evidence, management believes it is more-likely-than-not that the federal and state deferred tax assets will not be fully realized due to the Company’s cumulative losses. Accordingly, the Company has provided a valuation allowance on deferred tax assets in excess of deferred tax liabilities against its federal and state deferred tax assets as of December 31, 2021 and 2020. The valuation allowance increased by $17,934 and by $15,265 for the year ended December 31, 2021 and 2020, respectively.

The Company is not asserting permanent reinvestment of its unrepatriated foreign earnings under APB23. Management has analyzed the unrepatriated foreign earnings balances and determined that the following balances exist according to U.S. GAAP as of December 31, 2021: $972 in Canada, $0 in China, $5,681 in Germany, $159 in Japan and $0 in Korea. Based on the U.S. income tax treaties with Japan and Germany, the Company is entitled to a reduced 0% withholding rate on dividends from the Japanese and German subsidiaries (respectively). Under the U.S. income tax treaty with Canada, the withholding tax rate on dividends is reduced to 5%. Based on the unrepatriated earnings balance of $972, the effective tax liability is approximately $49. Management deems this amount to be immaterial to the financials.

As of December 31, 2021, the Company had net operating loss carry forwards of approximately $301,503 and $102,925 available to reduce future taxable income, if any, for both federal and state income tax purposes, respectively. Additionally, as of December 31, 2021, the Company had Germany net operating loss carryforwards of $3,383. The federal and state net operating loss carry forwards will start to expire in 2025 and 2028, respectively, with the exception of $212,867 in federal net operating loss carryforwards, which can be carried forward indefinitely. The Germany net operating losses can be carried forward indefinitely.

The Company also had federal and state research and development credit carry forwards of approximately $8,900 and $7,993, respectively, at December 31, 2021. The federal credits will expire starting in 2029 if not utilized. State research and development tax credits will carry forward indefinitely.

Under Sections 382 and 383 of the Internal Revenue Code of 1986 and similar state tax laws, if a corporation undergoes an ownership change, the utilization of net operating loss carryforwards and other tax attributes could be subject to an annual limitation. The annual limitation may result in the expiration of the net operating loss carryforwards and credits carryforwards before utilization. The Company has not undertaken a study to determine if ownership change has occurred as defined under IRC Section 382. In the event the Company previously experienced an ownership change, or should experience an ownership change in the future, the amount of net operating losses and research and development credit carryovers, which are reserved by a full deferred tax asset valuation allowance, could be limited and may expire unutilized.

As of December 31, 2021, the Company has not filed its 2019 Germany income tax return. Accordingly, the Company has recognized $474 of interest and penalties expected to be owed with the late filing of the 2019 Germany income tax return, which have been included as other expense in the Company’s statement of operations with its consolidated financial statements.

The Company’s tax years 2006 to 2021 will remain open for examination by the federal and state authorities for three and four years, respectively, from the date of utilization of any net operating loss credits.

On March 27, 2020 and December 27, 2020, the United States enacted the Coronavirus Aid, Relief, and Economic Security (CARES) Act and the Consolidated Appropriation Act (CAA), respectively, as a result of the Coronavirus pandemic, which contain among other things, numerous income tax provisions. Some of these tax provisions are expected to be effective retroactively for years ending before the date of enactment. The company has evaluated the current legislation and at this time, does not anticipate the CARES Act or the CCA to have a material impact on its financial statements.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Private Placement [Abstract]

Private Placement

Note 5 — Private Placement

Simultaneously with the closing of the IPO, the Sponsor and EarlyBirdCapital purchased an aggregate of 390,000 Private Units at a price of $10.00 per Private Unit in a private placement (the “Private Placement”), generating gross proceeds of $3,900,000.

On March 19, 2021, simultaneous with the exercise of the over-allotment option, the Sponsor and EarlyBirdCapital purchased an aggregate of 26,000 additional Private Units, at a purchase price of $10.00 per Private Unit, generating gross proceeds to the Company of $260,000.

The Private Units (and underlying Private Subunits, Private Shares, and Private Warrants) are identical to the Public Units except that the Private Warrants included in the Private Units: (i) will not be redeemable by the Company and (ii) may be exercised for cash or on a cashless basis, so long as they are held by the initial purchasers or any of their permitted transferees. If the Private Warrants are held by holders other than the initial purchasers or any of their permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by the holders on the same basis as the Public Warrants.

The Company’s initial stockholders have agreed (A) to vote the Private Shares contained in the Private Subunits in favor of any proposed Business Combination, (B) not to convert any Private Subunits in connection with a stockholder vote to approve a proposed initial Business Combination or sell any Private Shares to the Company in a tender offer in connection with a proposed initial Business Combination and (C) that the Private Subunits shall not participate in any liquidating distribution from the Trust Account upon winding up if a Business Combination is not consummated. In the event of a liquidation prior to the initial Business Combination, the Private Units will likely be worthless.

Founder Shares

On January 4, 2021, the Sponsor paid $25,000, or approximately $0.009 per share, to cover certain offering costs in consideration for 2,875,000 shares of common stock, par value $0.0001 (the “Founder Shares”). Up to 375,000 Founder Shares are subject to forfeiture by the Sponsor depending on the extent to which the underwriters’ over-allotment option is exercised. On March 10, 2021, the Company effected a stock dividend of 0.2 shares for each founder share outstanding, resulting in an aggregate of 3,450,000 founder shares outstanding and held by the Sponsor and the Company’s directors (up to 450,000 of which are subject to forfeiture by the Sponsor if the underwriters’ over-allotment option is not exercised in full). On March 19, 2021, the underwriters partially exercised the over-allotment option to purchase 1,300,000 Public Units. As a result, 125,000 founder shares were forfeited.

On the date of the IPO, the Founder Shares were placed into an escrow account maintained in New York, New York by Continental Stock Transfer& Trust Company, acting as escrow agent. Subject to certain limited exceptions, these shares will not be transferred, assigned, sold or released from escrow (subject to certain limited exceptions) for a period ending on (1) with respect to 50% of the founder shares, the earlier of one year after the date of the consummation of the Company’s initial Business Combination and the date on which the closing price of the Company’s shares of common stock equals or exceeds $12.50 per share (as adjusted for share splits, share capitalizations, reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period commencing after Company’s initial Business Combination and (2) with respect to the remaining 50% of the founder shares, one year after the date of Company’s consummation of the initial Business Combination, or earlier, in either case, if, subsequent to the initial Business Combination, the Company consummates a liquidation, merger, stock exchange or other similar transaction which results in all of the stockholders having the right to exchange their shares of common stock for cash, securities or other property.

Promissory Note — Related Party

On January 4, 2021, the Sponsor agreed to loan the Company up to $300,000 to be used for a portion of the expenses of the IPO (the “Promissory Note”). These loans were non-interest bearing, unsecured and were due at the earlier of March 31, 2021 or the closing of the IPO.

On February 1, 2021, the Sponsor funded to the Company $100,000 pursuant to the Promissory Note. On February 10, 2021, the Sponsor funded to the Company an additional $25,000 pursuant to the Promissory Note, for an aggregate amount of $125,000. On March 15, 2021, the Promissory Note in an aggregate amount of $125,000 was fully repaid by the Company to the Sponsor.

Related Party Loans

In order to meet the working capital needs following the consummation of the IPO if the funds not held in the Trust Account are insufficient, the Sponsor, initial stockholders, officers, directors and their affiliates may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion (“Working Capital Loans”). Each Working Capital Loan would be evidenced by a promissory note. The notes would either be paid upon consummation of the initial Business Combination, without interest, or, at the holder’s discretion, up to $1,500,000 of the notes may be converted into units at a price of $10.00 per unit. The units would consist of (i) one subunit, which consists of one share of common stock and one-quarter of one warrant, and (ii) one-quarter of one warrant, where the common stock and warrants would be identical to the common stock and warrants included in the Private Units. In the event that the initial Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay such loaned amounts, but no other proceeds from the Trust Account would be used for such repayment.

REVENUE RECOGNITION

3. REVENUE RECOGNITION

Revenue Recognition

The Company recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenues are generally recognized upon the transfer of control of promised products or services provided to customers, reflecting the amount of consideration the Company expects to receive for those products or services. The Company enters into contracts that can include various products or services, which are generally capable of being distinct and accounted for as separate performance obligations.

The Company derives its revenue primarily from the following performance obligations: (1) hosted services, (2) professional services and (3) monetization. Revenue is reported net of applicable sales and use taxes that are passed through to customers.

The Company’s arrangements with customers may contain multiple obligations. Individual services are accounted for separately if they are distinct — that is, if a service is separately identifiable from other items in the contract and a customer can benefit from it in its own or with other resources that are readily available to the customer.

The Company has the following performance obligations in contracts with customers:

Hosted Services

Hosted services, along with non-distinct customization, integration, maintenance and support professional services, allow customers to access the Houndify platform over the contract period without taking possession of the software. The contract terms of hosted services range from one year to twenty years.

The Company has determined that the hosted services arrangements are a single performance obligation comprised of a series of distinct services, since each day of providing access to hosted services is substantially the same and the customer simultaneously receives and consumes the benefits as access is provided. These services are provided either on a usage basis (i.e., variable consideration) or on a fixed fee subscription basis. The Company recognizes revenue as each distinct service period is performed (i.e., recognized as incurred).

Hosted services generally include up-front services to develop and/or customize the Houndify application to each customer’s specification. Judgement is required to determine whether these professional services are

distinct from the hosted services. In making this determination, factors such as the degree of integration, the customers’ ability to start using the software prior to customization, and the availability of these services from other independent vendors are considered.

In instances where the Company concluded that the up-front services are not distinct performance obligations, revenue for these activities is recognized over the period which the hosted services are provided and is included within hosted services revenue.

Professional Services

Revenue from distinct professional services, such as non-integrated development services, is either recognized over time based upon the progress towards completion of the project, or at a point in time at project completion. The Company assesses distinct professional services to determine whether the transfer of control is over-time or at a point in time. The Company considers three criteria in making their assessment including (1) the customer simultaneously receives and consumes the benefits; (2) the Company’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced; or (3) the Company’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. If none of the criteria are met, revenue is determined to be recognized at a point in time.

For distinct professional services determined to be recognized over-time, measuring the stage of completion of a project requires significant judgement and estimates, including actual efforts spent in relation to estimated total costs and percentage of completion based on input and output measures. During the year ended December 31, 2021, $2,446 of professional service revenue was recognized over time, with the remaining $4,696 recognized at a point in time when the performance obligation was completed and control of the service was transferred to the customer. During the year ended December 31, 2020, $2,194 of professional service revenue was recognized over time, with the remaining $886 recognized at a point in time when the performance obligation was completed and control of the service was transferred to the customer.

Monetization

Monetization revenues are primarily derived from advertising payments associated with ad impressions placed on the SoundHound music identification application. The Company derives an immaterial amount of revenue from, sales commissions earned from song purchases facilitated by the SoundHound app and App store fees paid for ads-free downloads of the SoundHound music identification app. The amount of revenue is based on actual monetization generated or usage, which represent a variable consideration with constrained estimates. Therefore, the Company recognizes the related revenues at a point in time when advertisements are placed, when commissions are paid or when the SoundHound application is downloaded. The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether the Company is acting as a principal or an agent in the transaction. The Company has determined that it does not act as the principal in monetization arrangements because it does not control the transfer of the service and it does not set the price. Based on these factors, the Company reports revenue on a net basis.

When a contract has multiple performance obligations, the transaction price is allocated to each performance obligation based on its relative estimated standalone selling price (“SSP”). Judgments are required to determine the SSP for each distinct performance obligation. SSP is determined by maximizing observable inputs from pricing of standalone sales, when possible. Since prices vary from customer to customer based on customer relationship, volume discount and contract type, in instances where the SSP is not directly observable, the Company estimates SSP by considering the following factors:

• Costs of developing and supplying each performance obligation

• Industry standards

• Major product groupings

• Gross margin objectives and pricing practices, such as contractually stated prices, discounts offered, and applicable price lists

These factors may vary over time, depending upon the unique facts and circumstances related to each deliverable. If the facts and circumstances underlying the factors considered change or should future facts and circumstances lead the Company to consider additional factors, the Company’s best estimate of SSP may also change.

For the years ended December 31, 2021 and 2020, revenues under each performance obligation were:

	December 31,
	2021		2020
Hosted services	$	12,764	$	8,563

For the years ended December 31, 2021 and 2020, the disaggregated revenue by recognition pattern is as follows:

	December 31,
	2021		2020
Over time revenue	$	15,210	$	10,757
Point-in-time		5,987		2,260
Total	$	21,197	$	13,017

The Company also disaggregates revenue by service type. This disaggregation consists of Product Royalties, Service Subscriptions and Monetization. Product Royalties revenue is derived from Houndified Products, which are voice-enabled tangible products across the automotive and consumer electronics industries. Revenue from Product Royalties is based on volume, usage, or life of the products, which are driven by number of devices, users, or unit of time. Service Subscription revenue is generated through Houndified Services, which include customer services, food ordering, content, appointments, and voice commerce. Subscription revenue is derived from monthly fees based on usage-based revenue, revenue per query or revenue per user. Both Houndified Products and Houndified Services may include professional services that develop and customize the Houndify

platform to fit customers’ specific needs. Revenue from Monetization is generated from the SoundHound music identification app and is primarily attributable to user ad impression revenue. For the years ended December 31, 2021 and 2020, the disaggregated revenue by service type is as follows:

	December 31,
	2021		2020
Product Royalties	$	18,356	$	10,372
Service Subscriptions		1,550		1,271
Monetization		1,291		1,374
Total	$	21,197	$	13,017

Contract Balances

The Company performs its obligations under a contract with a customer by licensing access to software or providing services in exchange for consideration from the customer. The timing of the Company’s performance often differs from the timing of the customer’s payment, which results in the recognition of a receivable, a contract asset or a contract liability.

As of December 31, 2021 and 2020, the Company had contract assets included in prepaid expenses and other current assets of $54 and $43, respectively, in the consolidated balance sheets. The Company did not record any asset impairment charges related to contract assets during the year ended December 31, 2021.

Revenue recognized for the years ended December 31, 2021 and 2020 that was included in the deferred revenues balances at the beginning of the reporting period was $14,945 and $7,503, respectively. The significant decrease in deferred revenue as of December 31, 2021 compared to the beginning of the reporting period is primarily due to recognition of $4,346 revenue related to a one-time contract modification to reduce the scope of the Company’s performance obligation, in addition to satisfying its servicing performance obligations for other contracts. As of December 31, 2021, the aggregate amount of the transaction price allocated to the remaining performance obligations related to customer contracts that were unsatisfied or partially unsatisfied was $31,323. Given the applicable contract terms, $8,034 is expected to be recognized as revenue within one year and $14,858 is expected to be recognized between two to five years, with the remainder of $8,431 recognized after five years. This amount does not include contracts to which the customer is not committed, contracts for which the Company recognizes revenue equal to the amount the Company has the right to invoice for services performed, or future sales-based or usage-based royalty payments in exchange for access to the Company’s hosted services. This amount is subject to change due to future revaluations of variable consideration, terminations, other contract modifications or currency adjustments. The estimated timing of the recognition of remaining unsatisfied performance obligations is subject to change and is affected by changes to scope, changes in timing of delivery of products and services, or contract modifications.

The Company’s long-term contracts do not have significant financing components, as there is generally payment and performance in each year of the contract. If there is a period of one year or longer between the transfer of promised services and payment, it is generally for reasons other than financing and, thus, the Company does not adjust the transaction price for financing components.

The Company elected the practical expedient to not adjust promised amounts of consideration for the effects of a significant financing component if the Company expects, at contract inception, that the period between when the Company transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less.

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Commitments and Contingencies	Note 8 — Commitments and Contingencies Registration Rights The holders of the Founder Shares and Representative Shares (as defined below) issued and outstanding on the date of the IPO, as well as the holders of the Private Units and any units the Sponsor, officers, directors or their affiliates may be issued in payment of Working Capital Loans made to the Company (and all underlying securities), will be entitled to registration rights pursuant to an agreement signed on March 10, 2021. The holders of a majority of these securities are entitled to make up to two demands that the Company use its best efforts to register such securities. The holders of the majority of the Founder Shares can elect to exercise these registration rights at any time commencing three months prior to the date on which these shares of common stock are to be released from escrow. The holders of a majority of the Representative Shares, Private Units and units issued to the Sponsor, officers, directors or their affiliates in payment of Working Capital Loans made to the Company (or underlying securities) can elect to exercise these registration rights at any time after the Company consummates a Business Combination. Notwithstanding anything to the contrary, EarlyBirdCapital may only make a demand on one occasion and only during the five-year period beginning on March 10, 2021. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the consummation of a Business Combination; provided, however, that EarlyBirdCapital may participate in a “piggy-back” registration only during the seven-year period beginning on the effective date of the registration statement. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriters Agreement EarlyBirdCapital and I-Bankers Securities, Inc. (the “Underwriters”) have a 45-day option from the date of the IPO to purchase up to an additional 1,800,000 Public Units to cover over-allotments, if any. The Underwriters were entitled to a cash underwriting discount of two percent (2%) of the gross proceeds of the IPO, or $2,400,000 (or up to $2,760,000 if the underwriters’ over-allotment is exercised in full). On March 15, 2021, the Company paid, in aggregate, a fixed underwriting discount of $2,400,000. On March 19, 2021, the Underwriters partially exercised the over-allotment option to purchase 1,300,000 Public Units and were, in aggregate, paid a fixed underwriting discount of $260,000. EarlyBirdCapital will have the right of first refusal for a period commencing from the consummation of the IPO until the consummation of the initial Business Combination (or the liquidation of the Trust Account in the event that the Company fails to consummate the initial Business Combination within the Combination Period) to act as book running manager, placement agent and/or arranger for all financings where the Company seeks to raise equity, equity-linked, debt or mezzanine financings relating to or in connection with the initial Business Combination. In addition, under certain circumstances EarlyBirdCapital will be granted, for a period of one year from the closing of the IPO, the right to act as lead underwriter for the next U.S. registered public offering of securities, undertaken by any of the Company’s officers, for the purpose of raising capital and placing 90% or more of the proceeds in a trust or escrow account to be used to acquire one or more operating businesses in the technology industry that have not been identified at the time of the IPO. Business Combination Marketing Agreement The Company has engaged EarlyBirdCapital as an advisor in connection with the Business Combination to assist the Company in holding meetings with its stockholders to discuss the potential Business Combination and the target business’ attributes, introduce the Company to potential investors that are interested in purchasing the Company’s securities in connection with the initial Business Combination, assist the Company in obtaining stockholder approval for the Business Combination and assist the Company with its press releases and public filings in connection with the Business Combination. The Company will pay EarlyBirdCapital a cash fee for such services upon the consummation of its initial Business Combination in an amount equal to 3.5% of the gross proceeds of the IPO (exclusive of any applicable finders’ fees which will become payable); provided that up to 30% of the fee may be allocated at the Company’s sole discretion to other FINRA members (including, with EarlyBirdCapital’s prior consent which shall not be unreasonably withheld, companies affiliated with the Company or its officers or directors) that assist the Company in identifying or consummating an initial Business Combination. Representative Shares On January 13, 2021, the Company has issued to EarlyBirdCapital and its designees an aggregate of 350,000 representative shares at a purchase price of $0.0001 per share (the “Representative Shares”). The fair value of the Representative Shares was determined to be $2,024,463 (See Note 7). On March 10, 2021, the Company effected a stock dividend of 0.2 shares of common stock for every share of common stock outstanding, resulting in an additional 70,000 representative shares issued to EarlyBirdCapital for no consideration and an aggregate of 420,000 representative shares outstanding. The holders of the Representative Shares have agreed not to transfer, assign or sell any such shares without the Company’s prior consent until the completion of the initial Business Combination. In addition, the holders of the Representative Shares have agreed (i) to waive their conversion rights (or right to participate in any tender offer) with respect to such shares in connection with the completion of the initial Business Combination and (ii) to waive their rights to liquidating distributions from the Trust Account with respect to such shares if the Company fails to complete its initial Business Combination within the Combination Period. The Representative Shares have been deemed compensation by FINRA and are therefore subject to a lock-up for a period of 180 days immediately following March 10, 2021 pursuant to Rule 5110(g)(1) of the FINRA Manual. Pursuant to FINRA Rule 5110(g)(1), these securities will not be sold during the IPO, or sold, transferred, assigned, pledged, or hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the economic disposition of the securities by any person for a period of 180 days immediately following the March 10, 2021 or commencement of sales of the IPO, except to any underwriter and selected dealer participating in the IPO and their bona fide officers or partners, provided that all securities so transferred remain subject to the lock-up restriction above for the remainder of the time period. Business Combination Legal Services Agreement The Company has entered into an agreement with its legal counsel, Loeb & Loeb (“Loeb”), whereby the Company is required to pay a total of $250,000 in retainer fees to Loeb for services related to the initial Business Combination upon the completion of certain milestones. The balance of any additional legal fees incurred related to the initial Business Combination will be due at the closing of the SPAC Merger. As of December 31, 2021, the Company had paid a total of $50,000 of retainer fees to Loeb. Consulting Agreement On March 16, 2021, the Company entered into a consulting agreement with Dr. Julia, a director of the Company, pursuant to which Dr. Julia agreed to introduce to the Company one or more potential candidates for the Company to pursue regarding a potential business combination in exchange for a single consulting fee equal to 1.0% of the enterprise value of the target company paid in cash, not to exceed 2.0% of the Trust Account, payable concurrent with the closing of the business combination with the target introduced by Dr. Julia. On November 15, 2021, the Company entered into a Merger Agreement with SoundHound Inc., which Dr. Julia had introduced to the Company. Pursuant to the consulting agreement, upon the closing of the Business Combination, Dr. Julia will be entitled to a finder’s fee of $2.66 million.

Commitments and Contingencies	6. COMMITMENTS AND CONTINGENCIES Contracts In August 2021, the Company entered into an exclusive agreement with a cloud service provider to host its voice artificial intelligence platform pursuant to which the Company committed to pay $100,000 in cloud costs over a seven-year period contingent upon the successful completion of the Business Combination. Letters of Credit In conjunction with entering an 89-month lease in 2017 for the Santa Clara, California, facility, the Company agreed to issue a letter of credit for $1,656 to the landlord as a lease guarantee. The Company has cash equivalents deposited with a commercial bank as collateral against the letter of credit. The letter of credit was initially issued for a term of twelve months and is automatically renewed every twelve months for the entire term of the lease. If an event of default occurs, the landlord may draw upon the letter of credit. The letter of credit is reduced by $230 at the beginning of the 25th month of the lease, and annually thereafter, upon request of the Company. However, if during the period of the lease the Company’s tangible net worth is equal to or greater than $100,000, or the Company completes an initial public offering for the sale of its stock on a U.S. stock exchange for a total market capitalization of $300,000 or more, then the letter of credit will be reduced to $230. As of December 31, 2021, the Company’s letter of credit requirement was $1,196 with $460 recorded as current restricted cash equivalents as the Company did not request a $230 reduction during the year ended. As of December 31, 2020, the Company’s letter of credit requirement was $1,196 with $230 recorded as current restricted cash equivalents. Additionally, in conjunction with entering a five-year lease in 2015 for the San Francisco, California, facility, the Company agreed to issue a letter of credit for $94 as security for the Company’s performance of the provisions of the lease agreement. As of December 31, 2021, the restriction on cash expired. Legal Proceedings From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues contingent liabilities when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. In the opinion of management, there are no pending claims for which the outcome is expected to result in a material adverse effect on the financial position, results of operations or cash flows of the Company. Other Matters The Company has not historically collected U.S. state or local sales and use tax, or other similar taxes, in any jurisdiction. On June 21, 2018, the U.S. Supreme Court decided, in South Dakota v. Wayfair, Inc., that state and local jurisdiction may, in certain circumstances, enforce sales and use tax collection obligations on remote vendors that have no physical presence in such jurisdiction. A number of states have already begun, or have positioned themselves to begin, requiring sales and use tax collection from remote vendors. The details and effective dates of these collection requirements vary from state to state. The Company continues to analyze potential sales tax exposure using a state-by-state assessment, and estimated and recorded a liability as of December 31, 2021 and 2020, in accordance with ASC 450, Contingencies, of $1,105 and $829, respectively.

Note 1 — Organization and Business Operations

Organization and General

Archimedes Tech SPAC Partners Co. (the “Company”) is a blank check company formed under the laws of the State of Delaware on September 15, 2020. The Company was formed for the purpose of entering into a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar Business Combination with one or more businesses or entities (the “Business Combination”). The Company’s focus will be on the artificial intelligence, cloud services and automotive technology sectors. However, the Company is not limited to the technology industry, or these sectors therein, and the Company may pursue a Business Combination opportunity in any business or industry it chooses, and it may pursue a company with operations or opportunities outside of the United States.

The Company has selected December 31 as its fiscal year end.

As of December 31, 2021, the Company had not commenced any revenue-generating operations. All activity for the period from September 15, 2020 (inception) through December 31, 2021 relates to the Company’s formation, the initial public offering (the “IPO”) described below, and, since the closing of the IPO, the search for a prospective initial Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the IPO and will recognize changes in the fair value of warrant liability as other income or expense, as applicable.

On November 15, 2021, the Company entered into a definitive merger agreement with SoundHound Inc., a voice artificial intelligence company, pursuant to which the two companies agreed to consummate a Business Combination (the “Merger Agreement”). The total consideration to be paid by the Company to SoundHound Inc. is $2 billion in equity of the Company, with outstanding SoundHound Inc. stock options and warrants included on a net exercise basis. In connection with the Business Combination, certain accredited investors committed to purchase 11.1 million shares of Class A common stock of the combined company at a price of $10.00 per share, for total gross proceeds of $111 million, in a private placement that is scheduled to close concurrently with the Business Combination.

The Company’s sponsor is Archimedes Tech SPAC Sponsors LLC, a Delaware limited liability company (the “Sponsor”).

References to the Company’s “initial stockholders” refer to the Company’s stockholders prior to the IPO, excluding the holders of the Representative Shares (See Note 8).

Financing

The registration statement for the Company’s IPO was declared effective on March 10, 2021 (the “Effective Date”). As discussed in Note 4, on March 15, 2021, the Company consummated the IPO of 12,000,000 units, (the “Public Units”), at $10.00 per Public Unit, generating gross proceeds of $120,000,000.

Each Public Unit consists of (i) one subunit (the “Public Subunit”), which consists of one share of common stock (the “Public Share”) and one-quarter of one redeemable warrant, and (ii) one-quarter of one redeemable warrant (collectively, the redeemable warrants included in the Public Units and Public Subunits, the “Public Warrants”); each whole Public Warrant will be exercisable to purchase one share of common stock at a price of $11.50 per share.

Simultaneously with the closing of the IPO, the Company consummated the sale of 390,000 private units (the “Private Units”) at a price of $10.00 per Private Unit in a private placement (the “Private Placement”) to the Sponsor and EarlyBirdCapital, Inc. (“EarlyBirdCapital”), generating gross proceeds of $3,900,000, which is discussed in Note 5. Each Private Unit consists of (i) one subunit (the “Private Subunits”), which consists of one share of common stock (the “Private Shares”) and one-quarter of one redeemable warrant, and (ii) one-quarter of one redeemable warrant (collectively, the redeemable warrants included in the Private Units and Private Subunits, the “Private Warrants”).

Transaction costs amounted to $4,849,810 consisting of $2,400,000 of underwriting discount and $2,449,810 of other offering costs.

The Company granted the underwriters in the IPO a 45-day option to purchase up to 1,800,000 additional Public Units to cover over-allotments, if any. On March 19, 2021, the underwriters partially exercised the over-allotment option to purchase 1,300,000 Public Units, generating an aggregate of gross proceeds of $13,000,000, and incurred transaction costs of $260,000 in underwriting discount. In connection with the underwriters’ exercise of their over-allotment option, the Company also consummated the sale of an additional 26,000 Private Units at $10.00 per Private Unit to the Sponsor and EarlyBirdCapital, generating gross proceeds of $260,000.

Trust Account

Following the closing of the IPO on March 15, 2021 and the underwriters’ partial exercise of over-allotment option on March 19, 2021, $133,000,000 from the net proceeds of the sale of the Public Units in the IPO and the sale of the Private Units was placed in a trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee (the “Trust Account”). The funds held in the Trust Account is and will be invested only in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations, so that the Company is not deemed to be an investment company under the Investment Company Act. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Company to pay its income or other tax obligations, the proceeds will not be released from the Trust Account until the earlier of the completion of a Business Combination or the redemption of 100% of the outstanding Public Subunits if the Company has not completed a Business Combination in the required time period. The proceeds held in the Trust Account may be used as consideration to pay the sellers of a target business with which the Company completes a Business Combination. Any amounts not paid as consideration to the sellers of the target business may be used to finance operations of the target business.

Initial Business Combination

The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the value of the assets held in the Trust Account (excluding taxes payable on the interest earned on the Trust Account) at the time of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to complete a Business Combination successfully.

The shares of common stock subject to redemption are recorded at a redemption value and classified as temporary equity upon the completion of the IPO, in accordance with Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” In such case, the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the issued and outstanding shares voted are voted in favor of the Business Combination.

The Company will continue in existence only until 18 months from the closing of the IPO (the “Combination Period”). However, if the Company is unable to complete the initial Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up and (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the outstanding Public Subunits, at a per-subunit price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including any interest not previously released to the Company (net of taxes payable), divided by the number of then outstanding Public Subunits, which redemption will completely extinguish public stockholders’ rights as holders of Public Subunits (including the right to receive further liquidation distributions, if any), subject to applicable law. Public stockholders will also forfeit the one-quarter of one warrant included in the Public Subunits being redeemed. As promptly as

reasonably possible following such redemption, subject to the approval of the remaining stockholders and its board of directors, the Company will dissolve and liquidate, subject to its obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

A public stockholder will be entitled to receive funds from the Trust Account (including interest earned on his, her or its portion of the Trust Account to the extent not previously released to the Company) only in the event of (i) the redemption of 100% of the outstanding Public Subunits if the Company has not completed a Business Combination in the required time period, (ii) if that public stockholder converts such Public Subunits, or sells such Public Subunits to the Company in a tender offer, in connection with a Business Combination which the Company consummates or (iii) the Company seeks to amend any provisions of its amended and restated certificate of incorporation that would affect the public stockholders’ ability to convert or sell their Public Subunits to the Company in connection with a Business Combination or affect the substance or timing of the Company’s obligation to redeem 100% of the Public Subunits if the Company does not complete a Business Combination within the Combination Period. This redemption right shall apply in the event of the approval of any such amendment to the Company’s amended and restated certificate of incorporation, whether proposed by the Sponsor, initial stockholders, executive officers, directors or any other person. In no other circumstances will a public stockholder have any right or interest of any kind to or in the Trust Account.

The Sponsor, initial stockholders, officers and directors have agreed (1) to vote any shares of common stock owned by them in favor of any proposed Business Combination, (2) not to convert any shares in connection with a stockholder vote to approve a proposed initial Business Combination and (3) not to sell any shares in any tender in connection with a proposed initial Business Combination.

The Sponsor has agreed that it will be liable to ensure that the proceeds in the Trust Account are not reduced below $10.00 per Public Subunit by the claims of target businesses or claims of vendors or other entities that are owed money by the Company for services rendered or contracted for or products sold to the Company, but the Company cannot assure that it will be able to satisfy its indemnification obligations if it is required to do so. The Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believes that the Sponsor’s only assets are securities of the Company. Therefore, the Company believes it is unlikely that the Sponsor will be able to satisfy its indemnification obligations if it is required to do so.

Liquidity and Going Concern

As of December 31, 2021, the Company had cash outside the Trust Account of $235,295 available for its working capital needs. All remaining cash and securities were held in the Trust Account and is generally unavailable for the Company’s use prior to an initial Business Combination and is restricted for use either in a Business Combination or to redeem Public Subunits. As of December 31, 2021, none of the amount on deposit in the Trust Account was available to be withdrawn as described above.

Prior to the completion of the IPO, the Company’s liquidity needs had been satisfied through receipt of $25,000 from the sale of Founder Shares (see Note 6), advances from the Sponsor in an aggregate amount of $125,000 under an unsecured promissory note, which were repaid upon the closing of the IPO (see Note 6). Subsequent to the consummation of the IPO and Private Placement, the Company’s liquidity needs have been satisfied through the net proceeds from the IPO and Private Placement held outside of the Trust Account.

In addition, in order to finance transaction costs in connection with a Business Combination, the Company’s Sponsor, initial stockholders, officers, directors and their affiliates may, but are not obligated to, provide the Company Working Capital Loans, as defined below (see Note 6). To date, there were no amounts outstanding under any Working Capital Loans.

The Company anticipates that the $235,295 outside of the Trust account as of December 31, 2021 will not be sufficient to allow the Company to operate for at least the next 12 months, assuming that a Business Combination is not consummated during that time. Furthermore, if the Company is not able to consummate a Business Combination by September 15, 2022, it will trigger the Company’s automatic winding up, liquidation and dissolution. These conditions raise substantial doubt about the Company’s ability to continue as a going concern.

Stockholders' Equity

Note 9 — Stockholders’ Equity

Preferred Stock — The Company is authorized to issue 1,000,000 shares of preferred stock at par value of $0.0001 per share. As of December 31, 2021, there were no shares of preferred stock issued or outstanding.

Common Stock — The Company is authorized to issue 100,000,000 shares of common stock with a par value of $0.0001 per share. At December 31, 2021, there were 4,161,000 shares of common stock issued and outstanding, excluding 13,300,000 shares of common stock subject to possible redemption.

Public Warrants

Each whole warrant entitles the holder to purchase one common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of an initial Business Combination. The warrants will expire on the fifth anniversary of the completion of an initial Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

However, no warrants will be exercisable for cash unless the Company has an effective and current registration statement covering the shares of common stock issuable upon exercise of the warrants and a current prospectus relating to such shares of common stock. Notwithstanding the foregoing, if a registration statement covering the shares of common stock issuable upon exercise of the Public Warrants is not effective within 90 days following the consummation of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis. In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value”(defined below) by (y) the fair market value. The “fair market value” for this purpose will mean the average reported last sale price of the shares of common stock for the 5 trading days ending on the trading day prior to the date of exercise.

The Company may call the warrants for redemption (excluding the Private Warrants and any warrants underlying additional units issued to the Sponsor, initial stockholders, officers, directors or their affiliates in payment of Working Capital Loans made to the Company), in whole and not in part, at a price of $0.01 per warrant,

• at any time after the warrants become exercisable,

• upon not less than 30 days’ prior written notice of redemption to each warrant holder,

• If, and only if, the reported last sale price of the shares of common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations and recapitalizations), for any 20 trading days within a 30 trading day period commencing after the warrants become exercisable and ending on the third business day prior to the notice of redemption to warrant holders; and

• if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants.

In addition, if (x) the Company issues additional shares of common stock or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors, and in the case of any such issuance to the Sponsor, initial stockholders or their affiliates, without taking into account any Founder Shares held by them prior to such issuance), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (z) the Market Value is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the greater of (i) the Market Value or (ii) the price at which the Company issues the additional shares of common stock or equity-linked securities, and the $18.00 redemption trigger price will be adjusted to 180% of this amount.

The entire disclosure for shareholders' equity comprised of portions attributable to the parent entity and noncontrolling interest, including other comprehensive income. Includes, but is not limited to, balances of common stock, preferred stock, additional paid-in capital, other capital and retained earnings, accumulated balance for each classification of other comprehensive income and amount of comprehensive income.
