Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned domestic and foreign subsidiaries. All intercompany transactions and balances are eliminated upon consolidation. Reclassification Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation. Specifically, change in fair value of financing derivatives, accretion of debt discount, and amortization of deferred financing costs have been aggregated within other operating activities on the Condensed Consolidated Statements of Cash Flows. In addition, principal payments on software license arrangements, revolving line of credit issuance costs, and payments for taxes related to net share settlement of equity awards have been aggregated within other financing activities on the Condensed Consolidated Statements of Cash Flows. Unaudited Interim Financial Information The interim Condensed Consolidated Financial Statements included in this quarterly report have been prepared by the Company and are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("GAAP") have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures contained in this quarterly report comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), for a quarterly report on Form 10-Q and are adequate to make the information presented not misleading. The interim Condensed Consolidated Financial Statements included herein reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods presented. These interim Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2021 (the "2021 10-K"). The Condensed Consolidated Results of Operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2022 or thereafter. All references to June 30, 2022 and 2021 in the Notes to Condensed Consolidated Financial Statements are unaudited. Use of Estimates and Judgments in the Preparation of the Condensed Consolidated Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and the measurement of management's standalone selling price, principal versus agent revenue recognition, determination of performance obligations, determination of transaction price, including the determination of variable consideration and allocation of transaction price to performance obligations, deferred tax assets and liabilities, including the identification and quantification of income tax liabilities due to uncertain tax positions, the valuation and recoverability of goodwill, intangible and other long-lived assets, the determination of appropriate discount rates for lease accounting, the probability of exercising either lease renewal or termination clauses, the assessment of potential loss from contingencies, the fair value determination of contingent consideration from business combinations, financing-related liabilities and warrants, and the valuation of options, performance-based and market-based stock awards. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. The Company evaluates its estimates and assumptions on an ongoing basis. Business Combination In December 2021, the Company and two newly formed, wholly owned subsidiaries of the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Shareablee, Inc. ("Shareablee"), pursuant to which the Company acquired Shareablee (the "Merger"). Total consideration paid or payable by the Company related to the Merger (valued as of the closing date of the Merger) was $31.4 million, which included $5.6 million for the fair value of contingent consideration payable based on the achievement of certain contractual milestones or future revenue performance. The maximum amount of contingent consideration payable under the Merger is $8.6 million. The contingent consideration is classified as a liability due to the fact it will be settled in cash or a variable number of shares of the Company's common stock, par value $0.001 ("Common Stock") (or a combination thereof), and the amount of the payment is not dependent upon the fair value of the Common Stock. The contingent consideration liability is measured at fair value on a recurring basis until the contingency is resolved. The fair value of the contingent consideration liability is estimated using a combination of valuation techniques. One technique is an option pricing model within a Monte Carlo simulation that determines an average projected payment value across numerous iterations. This technique determines projected payments based on simulated revenues derived from an internal forecast, adjusted for a selected revenue volatility and risk premium based on market data for comparable guideline public companies. The other technique is a discounted cash flow model that assumes achievement of the contractual milestones, resulting in payment of the full deferred amount. In both techniques, the projected payments are then discounted back to the valuation date at the Company's cost of debt using a term commensurate with the contractual payment dates. In March 2022, the Company determined sufficient achievement of the milestones had been demonstrated and the full amount of the contingent consideration was reasonably certain to be payable. In April 2022, the contingency was resolved and the full amount was deemed payable, subject to reduction for any pending indemnification claims and other terms set forth in the Merger Agreement. The resolution of this contingency eliminated the option pricing model as a valuation technique, and as a result the fair value was remeasured using only the discounted cash flow model. The Company expects to settle the liability in three installments of $3.7 million, $3.7 million and $1.2 million payable in any combination of cash and Common Stock (at the Company's election) in December 2022, 2023 and 2024, respectively. The estimated fair value of the contingent consideration liability as of June 30, 2022 was $8.0 million. The loss due to change in fair value of $2.4 million for the six months ended June 30, 2022 was classified within general and administrative expense in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The loss due to change in fair value for the three months ended June 30, 2022 was negligible. Refer to Footnote 6 , Fair Value Measurements , for additional information on the fair value of the contingent consideration. Preferred Stock In January 2021, the Company entered into separate Securities Purchase Agreements with each of Charter Communications Holding Company, LLC ("Charter"), Qurate Retail, Inc. ("Qurate") and Pine Investor, LLC ("Pine") (the "Securities Purchase Agreements") for the issuance and sale of shares of Series B Convertible Preferred Stock, par value $0.001 ("Preferred Stock") described in Footnote 4 , Convertible Redeemable Preferred Stock and Stockholders' Equity . The issuance of the Preferred Stock pursuant to the Securities Purchase Agreements (the "Transactions") and related matters were approved by the Company's stockholders on March 9, 2021 and completed on March 10, 2021. The Preferred Stock is contingently redeemable upon certain deemed liquidation events, such as a change in control. Because a deemed liquidation event could constitute a redemption event outside of the Company's control, all shares of Preferred Stock have been presented outside of permanent equity in mezzanine equity on the Condensed Consolidated Balance Sheets. The instrument was initially recognized at fair value net of issuance costs. The Company reassesses whether the Preferred Stock is currently redeemable, or probable to become redeemable in the future, as of each reporting date. If the instrument meets either of these criteria, the Company will accrete the carrying value to the redemption value. The Preferred Stock has not been adjusted to its redemption amount as of June 30, 2022 because a deemed liquidation event is not considered probable. The Preferred Stock includes a change of control put option which allows the holders of the Preferred Stock to require the Company to repurchase such holders' shares in cash in an amount equal to the initial purchase price plus accrued dividends. The change of control put option was determined to be a derivative liability. As of June 30, 2022, the probability of a change of control was determined to be remote and the fair value of the change of control derivative was determined to be negligible. Warrants Liability In June 2019, the Company issued warrants to CVI Investments, Inc. ("CVI") in connection with the private placement described in Footnote 4 , Convertible Redeemable Preferred Stock and Stockholders' Equity . The warrants were determined to be freestanding financial instruments that qualify for liability treatment as a result of net cash settlement features associated with a cap on the issuance of shares, under certain circumstances, or upon a change of control. Changes in the fair value of these instruments are recorded in other income (expense), net in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The fair value of each warrant is estimated utilizing an option pricing model. Significant valuation inputs include the price and expected volatility of the Company's Common Stock, risk-free rate, and the remaining term of the warrants. As of June 30, 2022, the probability of a change of control was determined to be remote and did not require an enhancement to the valuation technique. Loss on Extinguishment of Debt In March 2021, the Company recorded a $9.6 million loss on debt extinguishment related to the payoff of its senior secured convertible notes (the "Notes") and a foreign secured promissory note (the "Secured Term Note"). Loss on extinguishment of debt represents the difference between the carrying value of the Company's debt instruments and any consideration paid to its creditors in the form of cash or shares of the Company's Common Stock on the extinguishment date. These transactions are described in Footnote 5 , Debt . Other Income (Expense), Net Other income (expense), net represents income and expenses incurred that are generally not recurring in nature or are not part of the Company's normal operations. The following is a summary of the significant components of other income (expense), net: Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2022 2021 2022 2021 Change in fair value of warrants liability $ 4,560 $ (6,519) $ 6,995 $ (16,520) Change in fair value of financing derivatives — — — 1,800 Other (3) 11 (5) (62) Total other income (expense), net $ 4,557 $ (6,508) $ 6,990 $ (14,782) Loss Per Share The Company uses the two-class method to calculate net loss per share. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. Under the two-class method, earnings for the period are allocated between common stockholders and participating security holders based on their respective rights to receive dividends as if all undistributed book earnings for the period were distributed. Basic loss per share is computed by dividing total net loss available to common stockholders by the weighted-average number of common shares outstanding for the period. This includes the effect of vested and deferred restricted stock units granted to members of the Company's Board of Directors ("Board") and certain employees. These awards are expected to be settled in shares of Common Stock and generally distributed upon the earlier of the individual's separation from service or a change of control. Diluted loss per share includes the effect of potential common shares, such as the Company's Preferred Stock, Notes, warrants, stock options and restricted stock units, and contingent consideration liability to the extent the effect is dilutive. In periods with a net loss available to common stockholders, the anti-dilutive effect of these potential common shares is excluded and diluted net loss per share is equal to basic net loss per share. The following is a summary of the Common Stock equivalents for the securities outstanding during the respective periods that have been excluded from the computation of diluted net loss per common share, as their effect would be anti-dilutive: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Preferred stock (1) 87,255,753 82,527,609 85,708,361 51,350,512 Warrants 5,457,026 5,457,026 5,457,026 5,457,026 Stock options and restricted stock units 4,461,988 5,247,075 4,566,611 4,435,010 Contingent consideration (2) 4,174,757 — 4,174,757 — Senior secured convertible notes — — — 2,462,981 Total 101,349,524 93,231,710 99,906,755 63,705,529 (1) Includes the effect of potential Common Stock that would be issued to settle unpaid dividends accrued to holders of the Preferred Stock if they elected to convert their shares at the beginning of the period (or at the time of issuance, if later). (2) A contingent consideration liability was recognized as part of the Shareablee acquisition described in Footnote 2 , Summary of Significant Accounting Policies . The liability payments may be settled in any combination of cash or shares of Common Stock (at the Company's election) based on the volume-weighted average trading price of the Common Stock for the ten trading days prior to the date of each payment. Settlement of this liability in Common Stock could potentially dilute basic earnings per share in future periods. The Company calculated a potential anti-dilutive share count based on the expected payments totaling $8.6 million and the $2.06 per share closing price of the Company's Common Stock on the Nasdaq Global Select Market on June 30, 2022. Income Taxes A significant portion of the Company's net operating loss carryforwards are subject to an annual limitation under Section 382 of the Internal Revenue Code. The Company anticipates the Transactions may have triggered further limitations but has not yet reached a final conclusion as to whether an ownership change occurred and to what extent its net operating loss carryforwards are further limited. If an ownership change occurred as a result of the Transactions, the annual limitation under Section 382 may cause a significant portion of the Company's net operating loss carryforwards to expire prior to use. Due to the Company's valuation allowance position in the United States, the required revaluation of its |
