Leases [Abstract]

Leases

Note 3: Leases

The Company adopted FASB ASC Topic 842, Leases (ASC 842) on January 1, 2019 and used the effective date of January 1, 2019 as its date of initial application. The primary impact upon adoption of the standard relates to the recognition of new right-of-use (“ROU”) assets and lease liabilities on the Company’s balance sheet for its office and operating leases and providing significant new disclosures about its leasing activities. On adoption, the Company recognized additional operating lease liabilities of approximately $8.7 million based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases and ROU assets of approximately $7.4 million.

The standard also provides practical expedients for an entity’s ongoing accounting. The Company elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company did not recognize ROU assets or lease liabilities, and this included not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for all of its leases.

The Company has an operating lease for office space for its corporate headquarters in Seattle, Washington. It also has operating leases for office space in Mississauga, Canada and Wichita, Kansas. The Company recognizes our operating lease agreements in accordance with ASC 842 and recognizes rent expense on a straight-line basis over the lease term with any lease incentives amortized as a reduction of rent expense over the lease term.

The Company’s lease agreement with respect to office space in Seattle, Washington, as amended, expires on March 31, 2025. The Company has the option to terminate the lease in March 2023, subject to satisfaction of certain conditions, including a payment of a termination fee of approximately $671,000. In addition, as part of the agreement, the lessor paid towards the cost of certain leasehold improvements (“landlord contribution”) of which the Company could use approximately $180,000 of unused landlord contribution as a credit against any payment obligation under the lease. In the second quarter of 2019, the Company requested the $180,000 landlord contribution from the lessor as a reimbursement towards certain leasehold improvements and received those funds in the third quarter of 2019. In the first quarter of 2018, the lessor paid $373,000 towards certain leasehold improvements which the Company accounted for as a lease incentive and is amortizing as a reduction of rent expense over the lease term. Additionally, in April 2018, the lessor refunded the previously provided security deposit and the Company provided a letter of credit to the lessor in the amount of $575,000, which will be reduced by $100,000 annually starting in April 2019. The letter of credit was collateralized by a $575,000 certificate of deposit, which was restricted in use and is included in other assets in the Company’s Condensed Consolidated Balance Sheet as of March 31, 2019. On April 2, 2019, the Company was no longer required to collateralize the letter of credit and the certificate of deposit matured. Additionally, in the third quarter of 2020, the Company concluded that exercising its option to terminate this office lease in March 2023 had met the reasonably certain threshold and as such, the Company remeasured its ROU asset and liability associated with this lease as of September 30, 2020 based on the expected termination fee payment of approximately $671,000 and a lease termination date of March 2023. In September 2022, we provided notice to the landlord exercising our option to terminate the lease. We are required to make payment of approximately $671,000 on or before the termination date. In December 2022, we procured alternative office space in the Seattle, Washington area, which our commencement date is April 1, 2023. The remaining lease obligation is classified within lease liability, current on our Consolidated Balance Sheet.

The Company’s lease agreement with respect to office space in Mississauga, Canada commenced in November 2016, with a lease term of 60 months, and expired on November 30, 2021. The Company has subsequently entered into a month-to-month lease and for disclosure purposes, we have selected the short-term lease election. We exercised our intent to exit the lease in February 2023. We do not plan to secure new office space in Canada.

The Company commenced a new lease for an office space in Wichita, Kansas in June 2020 which continues for a period of 66 months with an option to extend the term for two additional periods of three years each. The Company has the option to terminate the lease pursuant to certain terms as specified in the lease without any termination fees if notice is provided.

Lease cost recognized in the Company’s Consolidated Statements of Operations and other information is summarized as follows:

	Years Ended December 31,
(In Thousands)	2021			2022
Operating lease cost	$	1,862		$	1,943

Stockholders' Equity

Note 6: Stockholders' Equity

(a) Common Stock and Authorized Capital

The authorized capital stock of the Company consists of 1,000,000 shares of undesignated preferred stock and 125,000,000 shares of Class B common stock. The Company’s board of directors has the authority to issue up to 1,000,000 shares of preferred stock, $0.01 par value in one or more series and has the authority to designate rights, privileges and restrictions of each such series, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series.

The Company has two classes of authorized common stock: Class A common stock and Class B common stock. Except with respect to voting rights, the Class A and Class B shares have identical rights. Each share of Class A common stock is entitled to twenty-five votes per share, and each share of Class B common stock is entitled to one vote per share. Each share of Class A common stock is convertible at the holder’s option into one share of Class B common stock.

In accordance with the stockholders’ agreement signed by the founding Class A common stockholders, the following provisions survived the Company’s initial public offering: Class A stockholders other than Russell C. Horowitz may only sell, assign or transfer their Class A stock to existing Class A stockholders or to the Company and in the event of transfers of Class A stock not expressly permitted by the stockholders’ agreement, such shares of Class A stock shall be converted into shares of Class B common stock.

In November 2014, the Company’s board of directors authorized a new share repurchase program (the “2014 Repurchase Program”), which supersedes and replaces any prior repurchase programs. Under the 2014 Repurchase Program, the Company is authorized to repurchase up to 3 million shares of the Company’s Class B common stock in the aggregate through open market and privately negotiated transactions, at such times and in such amounts as the Company deems appropriate. Repurchases may also be made under a Rule 10b5-1 plan, which would permit shares to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, capital availability, and other market conditions. The 2014 Repurchase Program does not have an expiration date and may be expanded, limited or terminated at any time without prior notice. The Company has made no repurchases under the 2014 Repurchase Program for the years ended December 31, 2021 and 2022. During the year ended December 31, 2020, a joint and equal tender from the Company and Edenbrook Capital LLC (an existing shareholder of the Company) (the "Offer") was completed for 10 million shares of the Company's Class B common stock at $2.15 per share, of which the Company's share of the repurchase totaled approximately $10.8 million for 5 million shares, which was not pursuant to the 2014 Repurchase Program. Shares repurchased but not yet retired by the Company are classified as treasury stock on the Consolidated Balance Sheet before retirement. Retirement of treasury stock results in reductions to common stock and additional paid-in capital.

In November 2018, the Company acquired 100% of the outstanding stock of Callcap for consideration of approximately $25 million in cash at closing and approximately 3.4 million shares of Class B common stock to be issued over the four year period following the acquisition date. The issuance of the shares for 2021 and 2022 have been deferred and will issue in 2023 as a result of conditional events occurring as specified in terms of the acquisition. In 2022, we paid $1.5 million in cash and agreed to transfer $335,000 in cash and/or equipment before November 2023 in exchange for settling our contractual obligation to issue 1.34 million of such shares. The cash consideration was recognized as a financing activity on our Consolidated Statements of Cash Flow.

In December 2019, the Company acquired 100% of the outstanding stock of Sonar for consideration of approximately $8.5 million in cash at closing and approximately 1.0 million shares of Class B common stock to be issued over the three-year period following the acquisition date, which have been issued in their entirely. The Company also agreed to issue up to approximately 389,000 shares of Class B common stock based upon the achievement of certain financial target goals by Sonar in 2020 which were not achieved. In 2023, the Company authorized a minority interest stock incentive plan, Sonar Technology Stock Incentive Plan, for the Sonar subsidiary which allows for grants of stock options, restricted stock units and restricted stock awards by Sonar to eligible participants at the discretion of the Plan’s Administrative Committee. The Plan authorizes up to 30% of Sonar’s current authorized shares may be issued with respect to awards granted under the plan.

(b) Stock Option Plan

The Company’s stock incentive plan (the “2021 Plan”), which was established in 2021, allows for grants of stock options, restricted stock units and restricted stock awards to eligible participants and such options may be designated as incentive or non-qualified stock options at the discretion of the 2021 Plan’s Administrative Committee. Prior to the 2021 Plan, the Company granted stock-based awards under its 2012 Stock Incentive Plan (the “2012 Plan”). No further awards were made under the 2012 Plan after December 31, 2021. The 2021 Plan authorizes up to 3,500,000 shares of Class B common stock that may be issued with respect to awards granted under the 2021 Plan, and provides that the total number of shares of Class B common stock for which options designated as incentive stock options may be granted shall not exceed 3,500,000 shares. Annual increases to each of these share limits are to be added on the first day of each fiscal year beginning on January 1, 2022 equal to 3% of the

outstanding common stock (including for this purpose any shares of common stock issuable upon conversion of any outstanding capital stock of the Company) or in the case of incentive stock options, the lesser of (i) 2,000,000 shares of Class B common stock, or (ii) 3% of the outstanding common stock (including for this purpose any shares of common stock issuable upon conversion of any outstanding capital stock of the Company), or (iii) such number as determined by the Company’s board of directors. As a result of this provision, the authorized number of shares available under the 2021 Plan was increased by 1,261,566 and 1,294,725 on January 1, 2022 and 2023, respectively, bringing the aggregate authorized number of shares available under the 2021 Plan to 6,056,291. The Company may issue new shares or reissue treasury shares for stock option exercises and restricted stock grants. Generally, stock options have 10-year terms and vest 25% each year either annually or quarterly, over a 4-year period and restricted stock awards and units vest 25% each year annually over a 4-year period.

The Company did not grant any options with exercise prices less than the then current market value during 2021 and 2022.

The Company measures stock-based compensation cost at the grant date based on the fair value of the award and recognizes it as expense over the vesting or service period, as applicable, of the stock award using the straight-line method. The Company accounts for forfeitures as they occur. Stock-based compensation has been included in the same lines as compensation paid to the same employees in the Consolidated Statements of Operations.

Stock-based compensation expense was included in the following operating expense categories:

	Years ended December 31,
(In Thousands)	2021		2022
Service costs	$	49	$	171
Sales and marketing		870		796
Product development		296		293
General and administrative		1,459		1,386
Total stock-based compensation	$	2,674	$	2,646

For the years ended December 31, 2021 and 2022, the income tax benefit related to stock-based compensation included in net loss was $0 for all periods due to the valuation allowance recorded on the deferred tax assets.

The Company uses the Black-Scholes option pricing model to estimate the per share fair value of stock option grants with time-based vesting. The Black-Scholes model relies on a number of key assumptions to calculate estimated fair values. For years ended December 31, 2021 and 2022, the expected life of each award granted was determined based on historical experience with similar awards, giving consideration to contractual terms, anticipated exercise patterns, and vesting schedules. Expected volatility is based on historical volatility levels of the Company’s Class B common stock and the expected volatility of companies in similar industries that have similar vesting and contractual terms. The risk-free interest rate is based on the implied yield currently available on U.S. Treasury issues with terms approximately equal to the expected life of the option. The Company uses an expected annual dividend yield in consideration of the Company’s common stock dividend payments, which we consider to be zero.

The following assumptions were used in determining the fair value of time-vested stock options granted for the periods indicated:

	Years Ended December 31,
	2021	2022
Expected life (in years)	4.00-6.25	4.00-6.25
Risk-free interest rate	0.64% - 1.35%	2.41% - 4.30%
Expected volatility	50% - 59%	51% - 63%
Weighted average expected volatility	55%	55%

Stock option, restricted stock award, and restricted stock unit activity during the period is as follows:

	Options and Restricted Stock available for grant (in thousands)			Number of options outstanding (in thousands)			Weighted average exercise price of options		Weighted average remaining contractual term (in years)		Aggregate intrinsic value (in thousands)
Balance at December 31, 2021		16,116			3,601		$	3.43		6.46	$	360
Increase to pool January 1, 2022		1,262			—
Options granted		(739	)		739		$	2.08
Restricted stock granted		(636	)		—
Restricted stock forfeited		22			—
Options exercised		2			(2	)	$	1.66
Options expired		439			(439	)	$	3.69
Options forfeited		133			(133	)	$	3.14
Balance at December 31, 2022		16,599			3,766		$	3.14		6.67	$	10
Options exercisable at December 31, 2022					2,113		$	3.74		5.00	$	3

Information related to stock compensation activity during the period indicated is as follows:

	Years Ended December 31,
	2021		2022
Weighted average fair value of options granted	$	1.21	$	1.06
Intrinsic value of options exercised (in thousands)	$	71	$	-
Total grant date fair value of restricted stock vested (in thousands)	$	1,786	$	1,321

At December 31, 2022, there was $1.9 million of unrecognized stock option compensation expense related to non-vested awards, which is expected to be recognized over a weighted average period of 2.8 years.

During the year ended December 31, 2022, gross proceeds recognized from the exercise of stock options was $3,000.

Restricted stock awards and restricted stock unit activity during the period is as follows:

	Shares/ Units (In Thousands)			Weighted Average Grant Date Fair Value
Unvested at December 31, 2021		1,518		$	2.80
Granted		636			2.06
Vested		(492	)		2.68
Forfeited		(22	)		3.66
Unvested at December 31, 2022		1,640			2.53

Restricted stock awards and restricted stock units are generally measured at fair value on the date of grant based on the number of awards granted and the quoted price of the Company’s common stock. Restricted stock awards and restricted stock units are expensed on a straight-line basis over the vesting or service period, as applicable, and forfeitures are recognized as they occur. Restricted stock units entitle the holder to receive one share of the Company’s Class B common stock upon satisfaction of certain service conditions.

At December 31, 2022, there was $2.2 million of unrecognized restricted stock compensation expense related to non-vested restricted stock, which is expected to be recognized over a weighted average period of 2.7 years.

On March 8, 2013, the Company’s board of directors adopted and in May 2013 the stockholders approved the 2014 Employee Stock Purchase Plan (“2014 ESPP”), which became effective on January 1, 2014. The Company authorized an aggregate of 225,000 shares of Class B common stock for issuance under the plan to participating employees. The 2014 ESPP provides eligible employees the opportunity to purchase the Company’s Class B common stock at a price equal to 95% of the closing price on the last business day of each purchase periods. The 2014 ESPP permits eligible employees to purchase amounts up to 15% of their compensation in the purchase period, and no employee is permitted to purchase stock worth more than $25,000 in any calendar year, valued as of the first day of each purchase period. During the year ended December 31, 2021, 29,854 shares were purchased at prices ranging from $2.44 to $2.91 per share. During the year ended December 31, 2022, 18,721 shares were purchased at prices ranging from $1.25 to $2.18 per share.

Accounting Policies [Abstract]

Description of Business and Summary of Significant Accounting Policies and Practices

Note 1: Description of Business and Summary of Significant Accounting Policies and Practices

(a) Description of Business and Basis of Presentation

Marchex, Inc. (the “Company”) was incorporated in the state of Delaware on January 17, 2003. The Company is a conversational analytics and solutions company that helps businesses connect, drive, measure, and convert callers into customers, and connects the voice of the customer to their business. We deliver data insights and incorporate AI-powered functionality that drives insights and solutions to help companies find, engage and support their customers across voice and text-based communication channels.

Divestiture

In October 2020, the Company sold its interests in certain assets related to its Local Leads Platform, Call Marketplace and other assets not related to core conversational analytics and sales engagement solutions. In connection with the divestiture, the Company entered into an administrative support services agreement with the related party purchaser pursuant to which the Company will provide services to the related party purchaser for a support service fee. See Note 10: Divestiture Support Services Agreement of the Notes to the Consolidated Financial Statements for further discussion.

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). The preparation of our Consolidated Financial Statements requires management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period, including the effects of COVID-19. The Company has used estimates related to several financial statement amounts, including revenues, allowance for doubtful accounts, allowance for advertiser credits, useful lives for property and equipment and intangible assets, valuation of intangible assets, the fair value of stock options awards, the impairment of goodwill, and the valuation allowance for deferred tax assets. Actual results could differ from those estimates.

Our Company consolidates all entities that we control by ownership of a majority voting interest. All inter-company transactions and balances have been eliminated in consolidation. Certain reclassifications have been made to the Consolidated Financial Statements in the prior periods to conform to the current period presentation.

Additionally, there are situations in which U.S. GAAP requires consolidation even though the usual condition of consolidation (ownership of a majority voting interest) does not apply. Generally, this occurs when an entity holds an interest in another business enterprise that was achieved through arrangements that do not involve voting interests, which results in a disproportionate relationship between such entity's voting interests in, and its exposure to the economic risks and potential rewards of, the other business enterprise. This disproportionate relationship results in what is known as a variable interest, and the entity in which we have the variable interest is referred to as a "VIE." An enterprise must consolidate a VIE if it is determined to be the primary beneficiary of the VIE. The primary beneficiary has both (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance and (2) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.

We held a remaining interest in the related party purchaser of our divested operations until we disposed of our interest in the third quarter of 2021. We determined during the period of holding an interest we were not the primary beneficiary. Our variable interests in this VIE primarily relate to the issuance of a 10% equity interest in the related party purchaser; contingent consideration related to the transaction; and an administrative support services arrangement. Refer to Note 10: Divestiture Support Services Agreement. Although this financial arrangement resulted in our holding variable interests in this related party entity, it did not empower us to direct the strategic and operational activities of the VIE that most significantly impact the VIE’s economic performance. Our Company's investment related to this VIE totaled $341,000 as of December 31, 2020, representing our maximum exposure to

loss. In the third quarter of 2021, we sold our equity interest for proceeds of $400,000. The Company's investment related to this VIE was not individually significant to the Company's Consolidated Financial Statements.

(b) Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. Cash equivalents consist primarily of money market funds.

The Company had the following financial instruments as of December 31, 2021 and 2022: cash and cash equivalents, accounts receivable, and accounts payable and accrued liabilities. The carrying value of these financial instruments approximates their fair value based on the liquidity of these financial instruments and their short-term nature. Further, these financial instruments are considered at Level 1 fair value with observable inputs that reflect quoted prices for identical assets or liabilities in active markets. The following table provides information about the fair value of our cash and cash equivalents balance:

	Years Ended December 31,
(In Thousands)	2021		2022
Level 1 Assets:
Cash	$	10,725	$	9,020
Money market funds		16,361		11,454
Total cash and cash equivalents	$	27,086	$	20,474

In addition, the Company has acquisition-related liabilities which are recorded at fair value. The fair value was estimated by applying the income approach, which is based on significant inputs that are not observable in the market (Level 3 inputs), such as the discount rate and the probability of meeting targeted financial goals.

Assets, liabilities, and operations of foreign subsidiaries are recorded based on the functional currency of the entity. For a majority of our foreign operations, the functional currency is the U.S. dollar. Assets and liabilities denominated in other than the functional currency is remeasured each month with the remeasurement gain or loss recorded in interest income and other, net in the Consolidated Statements of Operations.

(d) Accounts Receivable

Accounts receivable are recorded at the invoiced amount and do not bear interest. Accounts receivable balances are presented net of allowance for doubtful accounts and allowance for advertiser credits.

Allowance for Doubtful Accounts

The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in existing accounts receivable. The Company determines the allowance based on analysis of historical bad debts, advertiser concentrations, advertiser creditworthiness and current economic trends. Past due balances over 90 days and specific other balances are reviewed individually for collectability. The Company reviews the allowance for collectability quarterly. Account balances are written off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.

The allowance for doubtful accounts activity for the periods indicated is as follows:

(e) Property and Equipment

Property and equipment are stated at cost. Depreciation on computers and other related equipment, purchased and internally developed software, and furniture and fixtures are calculated on the straight-line method over the estimated useful lives of the assets, generally averaging three years. Leasehold improvements are amortized straight-line over the shorter of the lease term or estimated useful lives of the assets generally ranging from five to eight years.

We capitalize certain software development costs incurred in connection with developing or obtaining computer software for internal use when both the preliminary project stage is completed, and it is probable that the software will be used as intended. Capitalized software costs include (i) external direct costs of materials and services utilized in developing computer software, (ii) compensation and related benefits for employees who are directly associated with the software projects. Capitalized software costs are amortized on a straight-line basis when placed into service over the estimated useful life of the software, generally averaging three years. We capitalized software development costs of $1.0 million and $1.4 million for the year ended December 31, 2021 and 2022, respectively.

(f) Goodwill

Goodwill represents the excess of the purchase price over the fair value of identifiable assets acquired and liabilities assumed in business combinations accounted for under the purchase method, net of recognized impairment.

Goodwill acquired in a purchase business combination is not amortized, but instead tested for impairment at least annually, and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. As of the year ended December 31, 2021 and 2022, the Company had $17.6 million, respectively, of goodwill on its balance sheet, net of recognized impairment.

(g) Impairment or Disposal of Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds fair value. Assets to be disposed of would be separately presented on the balance sheet and reported at the lower of their carrying amount or fair value less costs to sell, and no longer depreciated.

(h) Revenue Recognition

We generate the majority of our revenues from core analytics and solutions services. Customers typically receive the benefit of the Company’s services as they are performed and substantially all the Company’s revenue is recognized over time as the services are performed.

Revenue is recognized when a customer obtains control of services in an amount that reflects the consideration the Company expects to receive in exchange for those services. The Company measures revenue based on the consideration specified in the customer arrangement, and revenue is recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct service or product to the customer. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as the customer receives the benefit of the performance obligation.

The Company’s call analytics technology platform provides data and insights that can measure the performance of mobile, online and offline advertising for customers and small business resellers. The Company generates revenue from the Company’s call analytics technology platform when advertisers pay the Company a fee for call, text, or other communication related data element they receive from calls or texts or for each phone number tracked based on a pre-negotiated rate. Revenue is recognized as services are provided over time, which is generally measured by the delivery of each call/text or call/text related data element or each phone number tracked.

The majority of the Company’s customers are invoiced on a monthly basis following the month of the delivery of services and are required to make payments under standard credit terms. The Company establishes an allowance for advertiser credits, which is included in accrued expense and other current liabilities in the balance sheet, using its best estimate of the amount of expected future reductions in advertisers’ payment obligations related to delivered services based on analysis of historical credits. The balance associated with the allowance for advertiser credits in the Company’s Consolidated Balance Sheet was $157,000 and $84,000 as of December 31, 2021 and 2022, respectively. Customer payments received in advance of revenue recognition are also contract liabilities and are recorded as deferred revenue. The deferred revenue balance in the Company’s Consolidated Balance Sheet as of December 31, 2021 and 2022, was $2.0 million and $1.4 million, respectively. During the year ended December 31, 2021 and 2022, revenue recognized that was included in the contract liabilities balances at the beginning of the period was $1.4 million and $1.1 million, respectively.

The majority of the Company’s total revenue is derived from contracts that include consideration that is variable in nature. The variable elements of these contracts primarily include the number of transactions (for example, the number qualified phone calls). For contracts with an effective term greater than one year, the Company applies the standard’s practical expedient that permits the exclusion of disclosure of the value of unsatisfied performance obligations for these contracts as the Company’s right to consideration corresponds directly to the value provided to the customer for services completed to date and all future variable consideration is allocated to wholly unsatisfied performance obligations. A term for purposes of these contracts has been estimated at 24 months. In addition, the Company applies the standard’s optional exemption to disclose information about performance obligations for contracts that have original expected terms of one year or less.

For arrangements that include multiple performance obligations, the transaction price from the arrangement is allocated to each respective performance obligation based on its relative standalone selling price and recognized when revenue recognition criteria for each performance obligation are met. The standalone selling price for each performance obligation is established based on the sales price at which the Company would sell a promised good or service separately to a customer or the estimated standalone selling price.

The Company’s incremental direct costs of obtaining a contract, which consist primarily of sales commissions, are generally deferred and amortized to sales and marketing expense over the estimated life of the relevant customer relationship of approximately 24 months and are subject to being monitored every period to reflect any significant change in assumptions. In addition, the deferred contract cost asset is assessed for impairment on a periodic basis. The Company’s contract acquisition costs are included in other assets, net in the balance sheet. The Company is applying the standard’s practical expedient permitting expensing of costs to obtain a contract when the expected amortization period is one year or less, which typically results in expensing commissions paid to acquire certain contracts. As of December 31, 2021 and 2022, the Company had $128,000 and $167,000 of net deferred contract costs, respectively, and the accumulated amortization associated with these costs was $1.2 million and $1.5 million for the year ended December 31, 2021 and 2022, respectively.

(i) Service Costs

Our service costs represent the cost of providing our services to our customers. These costs primarily consist of telecommunication costs, including the use of phone numbers relating to our services; colocation service charges of our network equipment; bandwidth and software license fees; network operations; and payroll and related expenses of personnel, including stock based compensation.

(j) Advertising Expenses

Advertising costs are expensed as incurred and include mobile and online advertising and related outside marketing activities, including sponsorships and trade shows. Such costs are included in sales and marketing. Advertising costs were approximately $1.4 million and $928,000 for the years ended December 31, 2021 and 2022 respectively.

(k) Product Development

Product development costs consist primarily of expenses incurred by the Company in the research and development, creation, and enhancement of the Company’s products and services. Research and development costs are expensed as incurred and include compensation and related expenses, costs of computer hardware and software, and costs incurred in developing features and functionality of the services. For the periods presented, substantially all of the product development expenses are research and development. Product development costs are expensed as incurred or capitalized into property and equipment in accordance with FASB ASC Topic 350, Intangibles – Goodwill and Other. FASB ASC Topic 350 requires that cost incurred in the preliminary project and post-implementation stages of an internal use software project be expensed as incurred and that certain costs incurred in the application development stage of a project be capitalized.

(l) Income Taxes

The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. 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 law is recognized in results of operations in the period that includes the enactment date.

(m) Stock-Based Compensation

The Company measures stock-based compensation cost at the grant date based on the fair value of the award and recognizes it as expense, over the vesting or service period, as applicable, of the stock award using the straight-line method. The Company accounts for forfeitures as they occur.

(n) Concentrations

The Company maintains substantially all of its cash and cash equivalents with two financial institutions and are all considered at Level 1 fair value with observable inputs that reflect quoted prices for identical assets or liabilities in active markets.

The Company had no customers that represented more than 10% of consolidated revenue for the year ended December 31, 2021 and 2022.

The Company has one customer that represents more than 10% of consolidated accounts receivable. The outstanding receivable balance for this customer is as follows:

	At December 31,
(In Percentages)	2021			2022
Customer A		11	%		28	%

(o) Net Income (Loss) Per Share

The Company computes net income (loss) per share of Class A and Class B common stock using the two class method. Under the provisions of the two class method, basic net income (loss) per share is computed by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the year. Diluted net income (loss) per share is computed by dividing net income (loss) applicable to common stockholders by the weighted average number of common and dilutive common equivalent shares outstanding during the period. The computation of the diluted net income (loss) per share of Class B common stock assumes the conversion of Class A common stock to Class B common stock, while the diluted net income (loss) per share of Class A common stock does not assume the conversion of those shares.

In accordance with the two class method, the undistributed earnings (losses) for each year are allocated based on the contractual participation rights of the Class A and Class B common shares and the restricted shares as if the earnings for the year had been distributed. Considering the terms of the Company’s charter which provides that, if and when dividends are declared on its common stock in accordance with Delaware General Corporation Law, equivalent dividends shall be paid with respect to the shares of Class A common stock and Class B common stock and that both classes of common stock have identical dividend rights and would share equally in the Company’s net assets in the event of liquidation, the Company has allocated undistributed earnings (losses) on a proportionate basis. See Note 6: Stockholders' Equity of the Notes to Consolidated Financial Statements for further discussion.

Instruments granted in unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities prior to vesting. As such, the Company’s restricted stock awards are considered participating securities for purposes of calculating earnings per share. Under the two class method, dividends paid on unvested restricted stock are allocated to these participating securities and therefore impact the calculation of amounts allocated to common stock.

The following table presents the computation of basic net loss per share for the periods ended:

	Years Ended December 31,
	2021						2022
(In Thousands, Except Per Share Amounts)	Class A			Class B			Class A			Class B

Diluted net loss applicable to common stockholders:	$	(466	)	$	(4,390	)	$	(889	)	$	(8,245	)

Denominator:
Weighted average number of shares outstanding used to calculate basic net loss per share		4,661			39,256			4,661			38,560
Conversion of Class A to Class B common shares outstanding		—			4,661			—			4,661
Weighted average number of shares outstanding used to calculate diluted net loss per share		4,661			43,917			4,661			43,221
Diluted net loss per share applicable to common stockholders	$	(0.10	)	$	(0.10	)	$	(0.19	)	$	(0.19	)

The computation of diluted net loss per share excludes the following because their effect would be anti-dilutive (in thousands):

•

For the years ended December 31, 2021 and 2022, outstanding options to acquire 3,601 and 3,766 shares, respectively, of Class B common stock.

•

For the years ended December 31, 2021 and 2022, 965 and 1,105 shares of unvested Class B restricted common shares, respectively.

•

For the years ended December 31, 2021 and 2022, 553 and 535 restricted stock units, respectively.

(p) Guarantees

FASB ASC Topic 460, Guarantees provides accounting guidance surrounding liability recognition and disclosure requirements related to guarantees. In the ordinary course of business, the Company is not subject to potential obligations under guarantees that fall within the scope of FASB ASC Topic 460 except for standard indemnification provisions that are contained within many of the Company’s agreements, and give rise only to the disclosure requirements prescribed by FASB ASC Topic 460.

In certain agreements, the Company has agreed to indemnification provisions of varying scope and terms with customers, vendors and other parties with respect to certain matters, including, but not limited to, losses arising out of the Company’s breach of agreements or representations and warranties made by the Company, services to be provided by the Company and intellectual property infringement claims made by third parties. As a result of these provisions, the Company may from time to time provide certain levels of financial support to contract parties to seek to minimize the impact of any associated litigation in which they may be involved. To date, there have been no known events or circumstances that have resulted in any material costs related to these indemnification provisions and no liabilities therefore have been recorded in the accompanying Consolidated Financial Statements. However, the maximum potential amount of the future payments the Company could be required to make under these indemnification provisions could be material.

(q) Recent Accounting Pronouncement Not Yet Effective

To date, there have been no recent accounting pronouncements not yet effective that are expected to have a material impact on our Consolidated Financial Statements.

Divestiture Support Services Agreement

Note 10: Divestiture Support Services Agreement

In October 2020, the Company sold certain assets related to its Local Leads Platform, Call Marketplace and other assets not related to core conversational analytics. The purchaser is a related party controlled by a shareholder and officers of the Company.

The Company received cash consideration at closing of approximately $2.3 million. No gain or loss on the sale of discontinued operations was recognized in the Consolidated Statement of Operations as it was sold to a related party. The net consideration received from the sale was recognized in the Company’s Consolidated Statements of Stockholder’s Equity. The sale also included (i) contingent consideration based on the achievement of certain revenue and thresholds from the Call Marketplace, Local Leads Platform and the purchaser’s total business; (ii) certain contingent sales transaction consideration; (iii) shares of Class B common stock in the purchaser equal to the issuance of a 10% equity interest; and (iv) the cancellation of Company stock options for 1.5 million shares currently held by two officers of the Company who were involved in the transaction.

In connection with the closing, the Company also entered into an administrative support services agreement with the related party purchaser pursuant to which the Company will provide services to the related party purchaser for a support services fee, with certain guaranteed payments to the Company in the first year and in the second year following closing. Support services fees related to this arrangement totaled $6.4 million for the year ended December 31, 2022 and $6.6 million for the year ended December 31, 2021 and are included in the Company’s Consolidated Statements of Operations, net of the related expenses, within Service costs, Sales and marketing, Product development, and General and administrative. As of December 31, 2022 and 2021, the net amount due from the purchaser of $663,000 and $630,000, respectively, is included in the Company’s Consolidated Balance Sheet within Prepaid expenses and other current assets.

In preparing our December 31, 2022 financial statements, we determined that our December 31, 2021 gross deferred tax balances related to intangible assets, stock-based compensation, state net operating losses, goodwill, and the corresponding valuation allowance were misstated by approximately $3.0 million. The net amount and impact are zero. We evaluated the materiality of the adjustment and concluded that its impact was not material on our financial statements taken as a whole and did not affect our balance sheet, statement of operations, stockholders’ equity or cash flows, for any periods presented. We have elected to present an “as reported” and “as adjusted” for the year ended December 31, 2021 in the tables above.

As of December 31, 2022, the Company’s federal and state NOL carryforwards were approximately $170.1 million and $58.8 million, respectively. Of the total federal net operating losses reported, we have accumulated $47 million with an indefinite life as of December 31, 2022. The remaining federal net operating losses and the state net operating losses will begin to expire in 2027 and 2028, respectively, for income tax purposes. As of December 31, 2022, the Company’s federal research and development credit carryforwards were $6.3 million, which will start expiring in 2029.

The Tax Reform Act of 1986 limits the use of NOL and tax credit carryforwards in certain situations where changes occur in the stock ownership of a company. The Company is not aware that any such change has occurred related to these specific tax attributes, or that the utilization of the carryforwards is limited such that these NOL or tax credit carryforwards will likely never be utilized. Accordingly, the Company has included these federal NOL and tax credit carryforwards in its deferred tax assets (subject to valuation allowance).

The Company has recorded a deferred tax asset for stock-based compensation recorded on unexercised non-qualified stock options and certain restricted shares and restricted share units. The ultimate realization of this asset is dependent upon the fair value of the Company’s stock when the options are exercised and when restricted shares or restricted share units vest, and generation of sufficient taxable income to realize the benefit of the related tax deduction.

The Tax Cuts and Jobs Act contained a provision which requires the capitalization of Section 174 costs incurred in years beginning on or after January 1, 2022. Section 174 costs are expenditures which represent research and development costs that are incident to the development or improvement of a product, process, formula,

invention, computer software, or technique. This provision changes the treatment of Section 174 costs such that the expenditures are no longer allowed as an immediate deduction but rather must be capitalized and amortized. We have included the impact of this provision, which results in a deferred tax asset of approximately $1.1 million as of December 31, 2022.

At December 31, 2021 and 2022, the Company recorded a valuation allowance of $49.6 million, and $51.8 million, respectively, against its federal, state, city and foreign net deferred tax assets, as it believes it is more likely than not that these benefits will not be realized. The net change in the total valuation allowance for each of the years ended December 31, 2021 and 2022 was $9.8 million and $2.2 million, respectively.

The Company regularly reviews deferred tax assets to assess whether it is more likely than not that the deferred tax assets will be realized and, if necessary, establishes a valuation allowance for portions of such assets to reduce the carrying value. In assessing whether it is more likely than not that the Company’s deferred tax assets will be realized, factors considered included: historical taxable income, historical trends related to customer usage rates, projected revenues and expenses, macroeconomic conditions, issues facing the industry, existing contracts, the Company’s ability to project future results and any appreciation of its other assets. The Company incurred taxable losses from 2016 through 2022. Based on the level of historical taxable losses and the uncertainty of projections for future taxable income over the periods for which the deferred tax assets are deductible, with the exception of certain insignificant foreign deferred tax assets, the Company concluded that it is not more likely than not that the gross deferred tax assets will be realized.

From time to time, various state, federal and other jurisdictional tax authorities undertake audits of the Company and its filings. In evaluating the exposure associated with various tax filing positions, the Company on occasion accrues charges for uncertain positions. Resolution of uncertain tax positions will impact the Company’s effective tax rate when settled. The Company does not have any significant interest or penalty accruals. The provision for income taxes includes the impact of contingency provisions and changes to contingencies that are considered appropriate. The following table summarizes activity related to tax contingencies from January 1, 2021 to December 31, 2022 which are recorded as an offset to deferred tax assets (in thousands):

(In Thousands)
Gross tax contingencies—January 1, 2021	$	1,365
Gross increases to current period tax positions		72
Gross decreases to tax positions associated with prior periods		(55	)
Gross tax contingencies—December 31, 2021		1,382

Note 4: Commitments and Contingencies

(a) Commitments

The Company has commitments for future payments related to office facilities leases and other contractual obligations. The Company leases its office facilities under operating lease agreements in accordance with ASC 842 and recognizes rent expense on a straight-line basis over the lease term with any lease incentive amortized as a reduction of rent expense over the lease term. Other contractual obligations primarily relate to minimum contractual payments due to outside service providers.

Future minimum payments are approximately as follows:

(In Thousands)	Facilities operating leases		Other contractual obligations		Total
2023		1,540		2,502		4,042
2024		562		196		758

2027 and thereafter		380		—		380
Total minimum payments	$	3,448	$	2,698	$	6,146
(1) For additional information regarding the Company's facilities operating leases, see Note 3. Leases of the Notes to Consolidated Financial Statements for further discussion.

(b) Contingencies

The Company from time to time is a party to disputes and legal and administrative proceedings arising from the ordinary course of business. We could become in the future subject to legal proceedings, governmental investigations, and claims in the ordinary course of business, including employment claims, contract-related claims, and claims of alleged infringement of third-party patents, trademarks, and other intellectual property rights. Such claims, even if not meritorious, could force us to expend significant financial and managerial resources and could be material.

In some agreements to which the Company is a party to, the Company has agreed to indemnification provisions of varying scope and terms with customers, vendors and other parties with respect to certain matters, including, but not limited to, losses arising out of the Company’s breach of agreements or representations and warranties made by the Company, services to be provided by the Company and intellectual property infringement claims made by third parties. To date, there have been no known events or circumstances that have resulted in any material costs related to these indemnification provisions. However, the maximum potential amount of the future payments the Company could be required to make under these indemnification provisions could be material.

On October 21, 2022, the Shareholder Representatives for the former shareholders of Telmetrics, Inc. filed litigation against the Company in the U.S. District Court for the District of Delaware. The plaintiffs are asserting claims under a share purchase agreement and escrow agreement regarding entitlement to an earnout of up to $3 million and $1 million that was placed in escrow to secure indemnification obligations. On March 1, 2023, the Company filed a motion to compel arbitration and/or dismiss this litigation. On March 22, 2023, the plantiffs filed an amended complaint also seeking substantial punitive damages. While we believe we have meritorious defenses to

this lawsuit and are vigorously defending against it, litigation is inherently uncertain and we cannot currently predict the ultimate outcome of this matter.

While any litigation contains an element of uncertainty, the Company is not aware of any legal proceedings or claims which are pending that the Company believes, based on current knowledge, will have, individually or taken together, a material adverse effect on the Company’s financial condition, results of operations or liquidity.

The variable elements of these contracts primarily include the number of transactions (for example, the number qualified phone calls). For contracts with an effective term greater than one year, the Company applies the standard’s practical expedient that permits the exclusion of disclosure of the value of unsatisfied performance obligations for these contracts as the Company’s right to consideration corresponds directly to the value provided to the customer for services completed to date and all future variable consideration is allocated to wholly unsatisfied performance obligations. A term for purposes of these contracts has been estimated at 24 months. In addition, the Company applies the standard’s optional exemption to disclose information about performance obligations for contracts that have original expected terms of one year or less

Debt Instruments [Abstract]

CARES Act Loans and Foreign Wage Subsidy

Note 11: CARES Act Loans and Foreign Wage Subsidy

During the second quarter of 2020, the Company secured $5.3 million in promissory notes to bank lenders pursuant to government loan programs (collectively, the “Loans”). At December 31, 2020, the remaining balance was $5.1 million. The difference relates to the business operations divested in October 2020. The Loans were made under, and are subject to the terms and conditions of, the CARES Act and are administered by the U.S. Small Business Administration (“SBA”). The terms of the Loans were two years with maturity dates in the second quarter of 2022 and they contained a fixed annual interest rate of 1%. In the third quarter of 2021, we were legally released from our obligation as our application was approved by the SBA. We recognized a gain on extinguishment of $5.2 million in the 2021 Consolidated Statement of Operations. It is possible that the SBA could subsequently audit the forgiven Loans. The Company believes it was eligible to receive the Loans, calculated the loan amounts correctly, spent loan proceeds on allowable uses and is entitled to loan forgiveness. The Company will retain its financial documents relating to the Loans for six years as required.

In addition, under a foreign wage subsidy program in response to the COVID-19 pandemic, a subsidiary received approximately $444,000 and $10,000 in funding during the year ended December 31, 2021 and 2022, respectively, that were treated as reductions of payroll expenses.

Debt Instrument, Description		The terms of the Loans were two years with maturity dates in the second quarter of 2022 and they contained a fixed annual interest rate of 1%. In the third quarter of 2021, we were legally released from our obligation as our application was approved by the SBA. We recognized a gain on extinguishment of $5.2 million in the 2021 Consolidated Statement of Operations. It is possible that the SBA could subsequently audit the forgiven Loans. The Company believes it was eligible to receive the Loans, calculated the loan amounts correctly, spent loan proceeds on allowable uses and is entitled to loan forgiveness. The Company will retain its financial documents relating to the Loans for six years as required.
