Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of presentation and consolidation The Business Combination was accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Under this method of accounting, the Company is treated as the “acquired” company for financial reporting purposes and Hydrafacial is treated as the accounting acquirer. This determination was primarily based on the following: •the Hydrafacial stockholders as of immediately prior to the effective time of the First Merger considered in the aggregate have the largest minority interest of the voting power in the combined entity after taking into account actual redemptions; •the operations of Hydrafacial prior to the acquisition comprise the only ongoing operations of the post-combination company; •senior management of Hydrafacial comprises the senior management of the post-combination company; •the relative size and valuation of Hydrafacial compared to the Company; and •pursuant to that certain Investor Rights Agreement, dated as of May 4, 2021, by and between the Company and Hydrafacial, Hydrafacial was given the right to designate certain initial members of the board of directors of the Company immediately after giving effect to the transactions contemplated by the Merger Agreement. Consideration was also given to the fact that the Company paid a purchase price consisting of a combination of cash and equity consideration and its stockholders may have a significant amount of voting power, should the Company’s public stockholders be considered in the aggregate. However, based on the aforementioned factors of management, board representation, largest minority stockholder as noted above, and the continuation of the Hydrafacial business as well as its size, it was determined that accounting for the Business Combination as a reverse recapitalization was appropriate. Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Hydrafacial with the acquisition being treated as the equivalent of Hydrafacial issuing stock for the net assets of the Company, accompanied by a recapitalization. The net assets of the Company are stated at historical cost, with no goodwill or other intangible assets recorded. In connection with the Business Combination each share of Hydrafacial common stock outstanding immediately prior to the Business Combination converted into the right to receive 653.109 shares (the “Exchange Ratio”) of Class A Common Stock of the Company. The recapitalization of the number of shares of Class A Common Stock attributable to Hydrafacial is reflected retroactively to the earliest period presented based upon the Exchange Ratio and is utilized for calculating earnings per share in all prior periods presented. The Consolidated Financial Statements in this Annual Report on Form 10-K are presented in accordance with GAAP and include the Company’s consolidated domestic and international subsidiaries. Intercompany accounts and transactions have been eliminated. Use of estimates and assumptions in preparing consolidated financial statements In preparing its consolidated financial statements in conformity with GAAP, the Company makes assumptions, estimates, and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of net sales and expenses during the reported periods. On an ongoing basis, the Company evaluates its estimates, including, among others, those related to revenue related reserves, allowance for estimated credit losses, the realizability of inventory, fair value measurements including common stock, warrant liabilities and earn-out shares liability valuations, useful lives of property and equipment, goodwill and finite-lived intangible assets, accounting for income taxes, stock-based compensation expense and commitments and contingencies. The Company’s estimates are based on historical experience and on its future expectations that are believed to be reasonable. The combination of these factors forms the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from current estimates and those differences may be material. Cash and Cash Equivalents All highly liquid investments, including credit card receivables due from banks, with original maturities of 90 days or less at date of purchase, are reported at fair value and are considered to be cash equivalents. The balances of cash at financial institutions may exceed the federally insured limit. The Company has not experienced any losses in such accounts and believes its cash and cash equivalents are not subject to any significant credit risk. Accounts Receivable Accounts receivable primarily arise out of product purchases by customers from various distribution channels. Typical payment terms provide that customers pay within 30 to 120 days of the invoice. The allowance for estimated credit losses represents management's best estimate of probable credit losses in accounts receivable. The allowance is based upon a number of factors, including the length of time accounts receivable are past due, the Company’s previous loss history, the specific customer’s ability to pay its obligation and any other forward-looking data regarding customers’ ability to pay which may be available. In addition, management considered other qualitative factors, particularly in relation to the volatility in the economies of certain foreign jurisdictions that arose from the COVID-19 pandemic. Receivables are written off against the allowance when management believes that the amount receivable will not be recovered. Inventories Inventories are stated at the lower of cost (determined using the average cost method which approximates the first-in, first-out method) or net realizable value. Obsolete inventory or inventory in excess of management’s estimated usage is written-down to its estimated net realizable value. Inherent in the net realizable value are management’s estimates related to economic trends, future demand for products, and technological obsolescence of our products. Cost is determined using weighted-average costs, and includes all costs incurred to deliver inventory to the Company’s distribution centers including freight, non-refundable taxes, duty, and other landing costs. The Company periodically reviews its inventories and makes a provision as necessary to appropriately value goods that are obsolete, have quality issues, or are damaged. The amount of the provision is equal to the difference between the cost of the inventory and its net realizable value based upon assumptions about product quality, damages, future demand, selling prices, and market conditions. If changes in market conditions result in reductions in the estimated net realizable value of its inventory below its previous estimate, the Company would decrease its basis in the inventory in the period in which it made such a determination. Business Combinations The purchase price of an acquisition is measured as the aggregate of the fair value of the consideration transferred including the acquisition-date fair value of the Company’s previously held equity interests. The purchase price is allocated to the fair values of the tangible and intangible assets acquired and liabilities assumed, with any excess recorded as goodwill. These fair value determinations require judgment and may involve the use of significant estimates and assumptions. The purchase price allocation may be provisional during a measurement period of up to one year to provide reasonable time to obtain the information necessary to identify and measure the assets acquired and liabilities assumed. Any such measurement period adjustments are recognized in the period in which the adjustment amount is determined. Transaction costs associated with the acquisition are expensed as incurred. Goodwill Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the assets acquired and liabilities assumed. Goodwill is not amortized but is evaluated for impairment annually or more frequently if indicators of impairment are present or changes in circumstances suggest that impairment may exist. The Company has one reporting unit and management evaluates the carrying value of the Company’s goodwill annually at the end of its fiscal year or whenever events or changes in circumstances indicate that an impairment may exist. When testing goodwill for impairment, management has the option of first performing a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as the basis to determine if it is necessary to perform a quantitative goodwill impairment test. In performing the qualitative assessment, management considers the extent to which unfavorable events or circumstances identified, such as changes in economic conditions, industry and market conditions or company specific events, could affect the comparison of the reporting unit’s fair value with its carrying amount. If management concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, management is required to perform a quantitative impairment test. Quantitative impairment testing for goodwill is based upon the fair value of a reporting unit as compared to its carrying value. Under a quantitative impairment test, management will make certain judgments and assumptions in allocating assets and liabilities to determine carrying values for our reporting unit. The impairment loss recognized would be the difference between a reporting unit’s carrying value and fair value in an amount not to exceed the carrying value of the reporting unit’s goodwill. Testing goodwill for impairment requires management to estimate fair values of reporting units using significant estimates and assumptions. The assumptions made will impact the outcome and ultimate results of the testing. Management will use industry accepted valuation models and set criteria that are reviewed and approved by various levels of management and, in certain instances, we will engage independent third-party valuation specialists for advice. The key estimates and factors used in the valuation models would include revenue growth rates and profit margins based on our internal forecasts, our specific weighted-average cost of capital used to discount future cash flows, and comparable market multiples for the industry segment, when applicable, as well as our historical operating trends. Certain future events and circumstances, including deterioration of market conditions, higher cost of capital, a decline in actual and expected consumer consumption and demands, could result in changes to these assumptions and judgments. A revision of these assumptions could cause the fair values of the reporting units to fall below their respective carrying values, resulting in a non-cash impairment charge. Such charge could have a material effect on the consolidated financial statements. Intangible Assets Intangible assets are composed of developed technology, customer relationships and trademarks. At initial recognition, intangible assets acquired in a business combination are recognized at their fair value as of the date of acquisition. Following initial recognition, intangible assets are carried at cost less accumulated amortization and impairment losses, if any, and are amortized on a straight-line basis over the estimated useful life of the asset. We assess the impairment of intangible assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If necessary, we will use an industry accepted valuation model to estimate the fair value of the intangible assets. The fair value calculation requires significant judgments in determining both the assets’ estimated cash flows potentially the appropriate discount and royalty rates applied to those cash flows to determine fair value. Variations in economic conditions or a change in general consumer demands, operating results estimates or the application of alternative assumptions could produce significantly different results. If these assumptions differ materially from future results, we may record impairment charges in the future. Property and Equipment Property and equipment is stated at cost less accumulated depreciation. Repair and maintenance costs are expensed as incurred. Depreciation commences when an asset is ready for its intended use. Depreciation is recorded on a straight-line basis over each asset’s estimated useful life. Leasehold improvements are depreciated on a straight-line basis over the lesser of the length of the lease and the estimated useful life of the improvement. Impairment of long-lived Assets Long-lived assets, including intangible assets with finite lives, held for use are evaluated for impairment when the occurrence of events or a change in circumstances indicates that the carrying value of the assets may not be recoverable as measured by comparing their carrying value to the estimated undiscounted future cash flows generated by their use and eventual disposition. Impaired assets are recorded at fair value, determined principally by discounting the future cash flows expected from their use and eventual disposition. Reductions in asset values resulting from impairment valuations are recognized in income in the period that the impairment is determined. Leased Property and Equipment Prior to the adoption of ASU No. 2016-02, Leases (“ASC 842”), the Company recognized rent expense for operating leases on a straight‑line basis (including the effect of reduced or free rent and rent escalations) over the lease term. The difference between the cash paid to the landlord and the amount recognized as rent expense on a straight‑line basis was recognized as an adjustment to deferred rent in the consolidated balance sheets. Cash reimbursements received from landlords for leasehold improvements and other cash payments received from landlords as lease incentives were recorded as an asset and depreciated using the straight‑line method over the lease term as an offset to rent expense. ASC 842 became effective for the Company in the Annual Report on Form 10-K for the fiscal year ended December 31, 2021, with an effective date of January 1, 2021. Subsequent to the adoption of ASC 842 on January 1, 2021, the first day of fiscal 2021, operating and finance lease liabilities are recognized at the lease commencement date based on the present value of the fixed lease payments using the Company’s incremental borrowing rates for its population of leases. The Company uses an incremental borrowing rate to determine the present value of lease payments as the rate implicit in the lease is generally not readily determinable. The Company’s incremental borrowing rate is the rate of interest that it would have to pay to borrow an amount equal to the lease payments, on a collateralized basis and in a similar economic environment over a similar term. The Company determines if an arrangement is or contains a lease at inception. This determination depends on whether the arrangement conveys the right to control the use of an explicitly or implicitly identified asset for a period of time in exchange for consideration. Control of an underlying asset is conveyed if the Company obtains the right to direct the use of and obtains substantially all of the economic benefits from using the underlying asset. As a result of the adoption of the new accounting standard, the Company elected transition-related practical expedients as accounting policies which allowed it to not reassess, as of the adoption date, (1) whether any expired or existing contracts are or contain leases, (2) the classification of any expired or existing leases, and (3) if previously capitalized initial direct costs qualify for capitalization under ASC 842. The Company elected the practical expedient option to not separate lease and non-lease components for all of its leases, and also elected the short-term lease recognition exemption that keeps leases with an initial term of 12 months or less excluded from balance sheet capitalization. This results in recognizing those lease payments in the consolidated statements of operations on a straight-line basis over the lease term. Related operating and finance lease right-of-use assets are recognized based on the initial present value of the fixed lease payments, reduced by cash payments received from landlords as lease incentives, plus any prepaid rent and other direct costs from executing the leases. Amortization of both operating and finance lease right-of-use assets is performed on a straight-line basis and recorded as part of rent expense in cost of goods sold and selling, general and administrative expenses on the consolidated statements of operations. The interest expense amortization component of the finance lease liabilities is recorded within interest expense on the consolidated statements of operations. Convertible Senior Notes On September 14, 2021, the Company issued an aggregate of $750 million in principal amount of its 1.25% Convertible Senior Notes due 2026 (the “Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The Notes were issued pursuant to, and are governed by, an indenture (the “Indenture”), dated as of September 14, 2021, between the Company and U.S. Bank National Association, as trustee (the “Trustee”). The Company accounts for the Notes under Accounting Standards Codification (“ASC”) ASC 470-20 - Debt with Conversion and Other Options and Derivatives and Hedging—Contracts in Entity's Own Equity (“ASU 2020-06”), which the Company early adopted in the first quarter of 2021 concurrent with the issuance of the Notes. The Company records the Notes as a long-term liability at face value net of issuance costs. If any of the conditions to the convertibility of the Notes is satisfied, or the Notes become due within one year, then the Company may be required under applicable accounting standards to reclassify the carrying value of the Notes as a current, rather than a long-term liability. Refer to Note 10—Long-term Debt for further detail. Capped Call Transactions Capped call transactions cover the aggregate number of shares of the Company’s common stock that will initially underlie the Notes, and generally reduce potential dilution to the Company’s common stock upon any conversion of Notes and/or offset any cash payments the Company may make in excess of the principal amount of the converted Notes, as the case may be, with such reduction and/or offset subject to a cap, based on the cap price of the capped call transactions. The Company determined that the freestanding capped call option contracts qualify as equity under the accounting guidance on indexation and equity classification, and recognized the contract by recording an entry to “Additional paid-in capital” (“APIC”) in stockholders’ equity in its Consolidated Balance Sheet. The Company also determined that the capped call option contracts meet the definition of a derivative under ASC 815 — Derivatives and Hedging (“ASC 815”), but are not required to be accounted for as a derivative as they meet the scope exception outlined in ASC 815. The capped call options are recorded in APIC and not remeasured. Issuance Costs Issuance costs related to our Notes offering were capitalized and offset against proceeds from the Notes. Issuance costs consist of legal and other direct costs related to the issuance of the Notes and are amortized to interest expense over the term of the Notes. Refer to Note 10 – Long-term Debt for further detail. Warrant Liabilities During October 2020, in connection with Vesper’s initial public offering, the Company issued 15,333,333 warrants to purchase shares of the Company’s common stock at $11.50 per share (the “Public Warrants”). Simultaneously, with the consummation of Vesper’s initial public offering, the Company issued 9,333,333 warrants to purchase shares of the Company’s common stock at $11.50 per share (the “Private Placement Warrants”), to BLS Investor Group LLC (the “Sponsor”). On November 3, 2021 all of the Public Warrants that were outstanding were redeemed (the “Redemption Date”). As of December 31, 2022 and 2021, no Public Warrants were outstanding and approximately 7 million Private Placement Warrants remain outstanding. As of December 31, 2022 the Private Placement Warrants are measured at fair value using a Monte Carlo simulation because these warrants are not subject to redemption if the reference value of the common stock, as defined, is between $10.00 and $18.00 per share. The Private Placement Warrants are classified as a Level 3 financial instruments as of December 31, 2022. The Private Placement Warrants expire five years after the Business Combination. The Company classified the Public Warrants and currently classifies the Private Placement Warrants as liabilities on its Consolidated Balance Sheets as these instruments are precluded from being indexed to our own stock given the terms allow for a settlement adjustment that does not meet the scope of the fixed-for-fixed exception in ASC 815, Derivatives and Hedging. In certain events outside of the Company’s control, the Private Placement Warrant holders are entitled to receive cash while in certain scenarios the holders of the Company’s common stock are not entitled to receive cash or may receive less than 100% of any proceeds in cash, which precludes these instruments from being classified within equity pursuant to ASC 815-40. The Public and Private Placement Warrants were initially recorded at fair value on the date of the Business Combination and are subsequently adjusted to fair value at each subsequent reporting date. Changes in the fair value of these instruments are recognized within change in fair value of warrant liabilities in the Company’s Consolidated Statements of Comprehensive Income (Loss). Earn-out Shares Liability In addition to the consideration paid at the closing of the Business Combination, the former stockholders of Hydrafacial received contingent consideration in the form of an aggregate of 7.5 million shares of the Company’s Class A Common Stock (the “Earn-out Shares”) as a result of the Company’s completion of the acquisitions of four target businesses, as contemplated by the Merger Agreement, in June and July 2021 that were identified by Hydrafacial. With the closing of these four distributor acquisitions in Australia, France, Germany and Mexico, the 7.5 million Earn-out Shares were earned and subsequently issued on July 15, 2021. The Company accounted for the Earn-out Shares liability as contingent consideration and recorded an Earn-out Shares liability for the Earn-out Shares in accordance with ASC 480 – Distinguishing Liabilities from Equity. The liability was included as part of the consideration transferred in the Business Combination and was recorded at its then current fair value. The Earn-out Shares liability was recorded at fair value and remeasured at the end of each reporting period, with the corresponding gain or loss recorded in the Company’s Consolidated Statements of Comprehensive Income (Loss) as change in the fair value of earn-out shares liability. Revenue Recognition Net sales consist of the sale of products to retail and wholesale customers through e-commerce and distributor sales. The Company generates revenue through manufacturing and selling Hydrafacial Delivery Systems (“Delivery Systems”). In conjunction with the sale of Delivery Systems, the Company also sells its serum solutions and consumables (collectively “Consumables”). Original Consumables are sold solely and exclusively by the Company (and from authorized retailers) and are available for purchase separately from the purchase of Delivery Systems. For both Delivery Systems and Consumables, revenue is recognized upon transfer of control to the customer, which generally takes place at the point of shipment. The Company distributes products to customers both through national and international retailers as well as direct-to-consumers through its e-commerce and store channels. The Company sells to direct customers, including non-corporate customers (such as spas and dermatologist offices), corporate customers, and international distributors. For non-corporate customers, a contract exists when the customer initiates an order by submitting a purchase request. Such requests are accepted by the Company upon issuance of a corresponding invoice. For corporate customers, a contract exists when the customer submits a purchase order and is accepted upon issuance of a subsequent invoice. For distributors, a customer submits an order request which is processed in the system by a sales representative. This is also considered accepted upon the subsequent issuance of an invoice by the Company. For all customers, each invoice is considered a separate contract for accounting purposes. Revenue is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for the sale of its products which is determined based upon the sales price per the invoice or contract. Discounts applied to invoices are not associated with future purchases and solely relate to the product invoiced. As a result, the invoice and transaction price are recorded net of any discounts. The Company’s sales terms for its Delivery Systems allow for the right of return within 30 days, subject to a restocking fee. Estimates for variable consideration, which relate to sales returns associated with Delivery Systems, are based on the expected amount the Company will be entitled to receive, subject to constraint, and is recorded as a reduction against net sales. Sales returns are estimated based on historical sales and returns data and have not significantly impacted net sales because sales returns are not material. Depending on the type of Delivery System that was purchased, the Company offers its customers with a one-year or two-year standard type warranty that provides the customer with the assurance that its Delivery Systems will function as intended. Returns related to warranty have been immaterial. The Company also has a loyalty program that allows members to receive points based on qualifying Consumable purchases that may be redeemed as a discount on future consumable purchases. This customer option is a material right and, accordingly, represents a separate performance obligation to the customer. The related loyalty program deferred revenue included in other accrued expenses on the consolidated balance sheet was approximately $0.8 million and $1.2 million as of December 31, 2021 and 2022, respectively. In addition, during fiscal 2022 the Company provided certain customers with the option to trade-in their existing Delivery System and apply the fair value of their old Delivery System towards the transaction price of the Company’s new Syndeo Delivery System. The Company determined that the trade-in is viewed as a marketing offer due to the fact that it does not constitute the Company’s customary business practice and was not offered at contract inception. Therefore, the trade-in is accounted for under ASC 606 and represents a type of noncash consideration, which the Company measures at its estimated fair value. The estimated fair value represents the estimated selling price, less the cost to refurbish the inventory and the expected margin to be earned on the refurbishment, along with the expected margin to be earned on the selling effort. The estimated selling price is determined based on the Company’s historical experience of reselling refurbished Delivery Systems. The total value of these refurbished Delivery Systems included in inventory as of December 31, 2022 was $8.8 million. Payment terms vary by customer but typically provide for the customer to pay within 30 to 120 days; however, the Company provides an option for qualified customers to pay for Delivery Systems over 12 monthly installments. Therefore, customer payment terms are for 12 months or less and do not include significant financing components. The Company performs credit evaluations of customers and evaluates the need for allowances for potential credit losses based on historical experience, as well as current and expected general economic conditions. Cost of Sales The Company’s cost of sales consists of Delivery Systems and Consumables product costs, including the cost of materials, labor costs, overhead, depreciation and amortization of developed technology, shipping and handling costs, and the costs associated with excess and obsolete inventory. As the Company launches new products and expand presence internationally, the Company expects to incur higher cost of sales as a percentage of sales because we have not yet achieved economies of scale with these items. Selling and Marketing Expense Selling and marketing expense consists of personnel-related expenses, sales commissions, travel costs, and advertising expenses incurred in connection with the sale of our products. The Company intends to continue to invest in sales and marketing capabilities in the future and expect this expense to increase in absolute dollars in future periods as it releases new products, grow our global footprint, and drive consumer demand in the ecosystem. Selling and marketing expense as a percentage of total revenue may fluctuate from period to period based on total revenue and the timing of investments in sales and marketing functions as these investments may vary in scope and scale over future periods. Advertising costs are expensed in the period in which they are incurred. Total advertising costs, included in selling and marketing expenses on the Consolidated Statements of Comprehensive Income (Loss), were $3.8 million, $3.2 million and $3.3 million for each of the three years ending December 31, 2022, 2021, and 2020 respectively. Research and Development Costs Research and development expense primarily consists of personnel-related expenses, tooling and prototype materials, technology investments, and other expenses incurred in connection with the development of new products and internal technologies. The Company expects research and development expenses to increase in absolute dollars in future periods and vary from period to period as a percentage of total revenue, as the Company plans to continue to innovate and invest in new technologies and to enhance existing technologies to fuel future growth as a category creator. General and Administrative Expense General and administrative expense includes personnel-related expenses, professional fees, credit card and wire fees and facilities-related costs primarily for our executive, finance, accounting, legal, human resources, and IT functions. General and administrative expense also includes fees for professional services principally comprising legal, audit, tax and accounting services and insurance. The Company expects to continue to incur additional general and administrative expenses as a result of operating as a public company, including expenses related to compliance and reporting obligations of public companies, and increased costs for insurance, investor relations expenses, and professional services. In addition, the Company expects to continue to incur additional IT expenses as the Company scales and enhances its e-commerce, digital and data utilization capabilities. As a result, the Company expects that our general and administrative expenses will increase in absolute dollars in future periods and vary from period to period as a percentage of revenue. Interest Expense, Net Interest expense consists of interest accrued on the Company’s Convertible Senior Notes and amortization of debt issuance costs relating to the Notes. The Notes mature on October 1, 2026 and accrue interest at a rate of 1.25% per annum. Debt issuance costs are being amortized over the term of the Notes using the effective interest method. If the Notes are repurchased, redeemed, or converted prior to the maturity date, the interest on the Notes would no longer be accrued and the amortization of debt issuance costs would be accelerated. The Company expects interest expense to increase in absolute dollars as the Company grows internationally and obtains more financing to support such growth. Interest expense as a percentage of revenue will fluctuate period to period along with fluctuations in interest rates, which is not related to normal business operations. Interest Income Interest income consists of interest earned from investments in money market funds that the Company classifies as cash equivalents. Interest income as a percentage of revenue will fluctuate period to period along with fluctuations in interest rates, which is not related to normal business operations. Change in Fair Value of Warrant Liabilities In accordance with ASC 815-40 – Contracts in Entity's Own Equity, the Company’s Public and Private Placement Warrants are accounted for as liabilities in the Consolidated Balance Sheets and measured at fair value at inception and on a recurring basis, with changes in fair value presented within change in fair value of warrant liabilities in the Company’s Consolidated Statements of Comprehensive Income (Loss). There were no Public Warrants outstanding as of December 31, 2022. The value of the Private Placement Warrants was determined at year end using the Monte Carlo simulation model. Changes around share price volatility and assumptions and inputs used in the Monte Carlo model can result in an increase or decrease in fair value which can substantially impact the outstanding liability and the change in fair value of warrant liabilities. Changes in fair value of warrant liabilities as a percentage of revenue will fluctuate period to period along with fluctuations in fair value, which is not related to normal business operations. Change in Fair Value of Earn-out Shares Liability In accordance with ASC 480 – Distinguishing Liabilities from Equity, the Company accounted for its Earn-out Shares liability as contingent consideration and recorded an Earn-out Shares liability for the Earn-out Shares. The Earn-out Shares liability was recorded at fair value and remeasured at the end of each reporting period, with the corresponding gain or loss recorded in the Company’s Consolidated Statements of Comprehensive Income (Loss). The Earn-out shares were earned and subsequently issued on July 15, 2021. Foreign Currency Transaction (Gain) Loss, Net Foreign currency transaction gains and losses are generated by settlements of intercompany balances and invoices denominated in other currencies other than the reporting currency. Foreign currency gains and losses as a percentage of revenue will fluctuate period to period along with fluctuations in exchange rates, which is not related to normal business operations. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets (DTA)s and deferred tax liabilities (DTL)s for the expected future tax consequences of events that have been included in the financial statements. Under this method, we determine DTAs and DTLs on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on DTAs and DTLs is recognized in income in the period that includes the enactment date. The Company recognizes DTAs to the extent that it believes these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, carryback potential if permitted under the tax law, and results of recent operations. A valuation allowance is established, when necessary, to reduce deferred tax assets to the amount that is more likely than not to be realized based on currently available evidence. If the Company determines that it would be able to realize our DTAs in the future in excess of the net recorded amount, it would make an adjustment to the DTA valuation allowance, which would reduce the provision for income taxes. The Company would record uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) it determined whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. If any, the Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. Foreign Currency The functional currency for each entity included in these consolidated financial statements that is domiciled outside of the United States is generally the applicable local currency. Assets and liabilities of each foreign entity are translated into U.S. dollars at the exchange rate in effect on the balance sheet date. Net revenue and expenses are translated at the average rate in effect during the period. Unrealized translation gains and losses are recorded as a foreign currency translation adjustment, which is included in other comprehensive income or loss, which is a component of accumulated other comprehensive income or loss included in stockholders’ equity. Transactions between the parent company and its foreign subsidiaries are denominated in US Dollars. Accordingly, amounts due to or from the parent company are remeasured from local currency to its US Dollar equivalent on the balance sheet date. This remeasurement is recorded as a foreign currency transaction gain or loss in the consolidated statements of comprehensive income. Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company primarily maintains its operating cash balance with a major financial institution. At times, cash balances may be in excess of Federal Deposit Insurance Corporation insurance limits. The Company has not experienced any losses in these accounts and does not believe it is exposed to any significant credit risk in this area. Accounts receivable are unsecured and the Company is at risk to the extent such amounts become uncollectible. Concentration of credit risk with respect to accounts receivable is generally mitigated by the Company performing ongoing credit evaluations of its customers. Stock-based Compensation Stock-based compensation is accounted for under FASB ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). The Company accounts for all stock-based compensation transactions using a fair-value method and recognizes the fair value of each award as an expense over the service period. The Company estimates the fair value of stock options granted using the Black-Scholes option-pricing model. The use of the Black-Scholes model requires a number of estimates, including the expected option term, the expected volatility in the price of the Company’s common stock, the risk-free rate of interest and the dividend yield on the Company’s common stock. The fair value of the Company’s restricted stock units is the closing price of the Company’s common stock on the grant date. The fair value of the Company’s performance-based restricted stock units is estimated using a Monte Carlo simulation model. The consolidated financial statements include amounts that are based on the Company’s best estimates and judgments. The Company classifies compensation expense related to these awards in the Consolidated Statements of Comprehensive Income (Loss) based on the department to which the recipient reports. The Company’s policy is to account for forfeitures in period that they occur. Earnings per Share Earnings per share is calculated using the weighted-average number of common and exchangeable shares outstanding during the period. Exchangeable shares are the equivalent of common shares in all material respects. Diluted earnings per share is calculated by dividing net income available to stockholders for the period by the diluted weighted-average number of shares outstanding during the period. Diluted earnings per share reflects the potential dilution from common shares issuable through stock options, performance-based restricted stock units that have satisfied their performance factor, restricted shares, and restricted stock units using the treasury stock method. Fair Value of Financial Instruments 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 Notes that are recorded at historical cost was $567 million as of December 31, 2022, and was determined using the last trade price in active markets. With the exception of the Company’s Notes, the fair value of the Company’s assets and liabilities that are recorded at historical amounts and that qualify as financial instruments under ASC 820, Fair Value Measurement, approximates the carrying amounts represented in the Company’s Consolidated Balance Sheets, primarily due to their short-term nature. New Accounting Pronouncements Not Yet Adopted In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU 2021-08, Business Combinations (Topic 805), which primarily relates to the accounting for contract assets and contract liabilities from contracts with customers in a business combination. The standard will be effective for annual reporting periods beginning after December 31, 2022, including interim reporting periods within those periods, with early adoption permitted. We are currently evaluating the impact of adopting this new accounting guidance on our consolidated financial statements.

The Business Combination was accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Under this method of accounting, the Company is treated as the “acquired” company for financial reporting purposes and Hydrafacial is treated as the accounting acquirer. This determination was primarily based on the following:

•pursuant to that certain Investor Rights Agreement, dated as of May 4, 2021, by and between the Company and Hydrafacial, Hydrafacial was given the right to designate certain initial members of the board of directors of the Company immediately after giving effect to the transactions contemplated by the Merger Agreement.

Consideration was also given to the fact that the Company paid a purchase price consisting of a combination of cash and equity consideration and its stockholders may have a significant amount of voting power, should the Company’s public stockholders be considered in the aggregate. However, based on the aforementioned factors of management, board representation, largest minority stockholder as noted above, and the continuation of the Hydrafacial business as well as its size, it was determined that accounting for the Business Combination as a reverse recapitalization was appropriate.

Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Hydrafacial with the acquisition being treated as the equivalent of Hydrafacial issuing stock for the net assets of the Company, accompanied by a recapitalization. The net assets of the Company are stated at historical cost, with no goodwill or other intangible assets recorded.

In connection with the Business Combination each share of Hydrafacial common stock outstanding immediately prior to the Business Combination converted into the right to receive 653.109 shares (the “Exchange Ratio”) of Class A Common Stock of the Company. The recapitalization of the number of shares of Class A Common Stock attributable to Hydrafacial is reflected retroactively to the earliest period presented based upon the Exchange Ratio and is utilized for calculating earnings per share in all prior periods presented.

In preparing its consolidated financial statements in conformity with GAAP, the Company makes assumptions, estimates, and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of net sales and expenses during the reported periods. On an ongoing basis, the Company evaluates its estimates, including, among others, those related to revenue related reserves, allowance for estimated credit losses, the realizability of inventory, fair value measurements including common stock, warrant liabilities and earn-out shares liability valuations, useful lives of property and equipment, goodwill and finite-lived intangible assets, accounting for income taxes, stock-based compensation expense and commitments and contingencies. The Company’s estimates are based on historical experience and on its future expectations that are believed to be reasonable. The combination of these factors forms the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from current estimates and those differences may be material.

Accounts receivable primarily arise out of product purchases by customers from various distribution channels. Typical payment terms provide that customers pay within 30 to 120 days of the invoice. The allowance for estimated credit losses represents management's best estimate of probable credit losses in accounts receivable. The allowance is based upon a number of factors, including the length of time accounts receivable are past due, the Company’s previous loss history, the specific customer’s ability to pay its obligation and any other forward-looking data regarding customers’ ability to pay which may be available. In addition, management considered other qualitative factors, particularly in relation to the volatility in the economies of certain foreign jurisdictions that arose from the COVID-19 pandemic. Receivables are written off against the allowance when management believes that the amount receivable will not be recovered.

Inventories are stated at the lower of cost (determined using the average cost method which approximates the first-in, first-out method) or net realizable value. Obsolete inventory or inventory in excess of management’s estimated usage is written-down to its estimated net realizable value. Inherent in the net realizable value are management’s estimates related to economic trends, future demand for products, and technological obsolescence of our products. Cost is determined using weighted-average costs, and includes all costs incurred to deliver inventory to the Company’s distribution centers including freight, non-refundable taxes, duty, and other landing costs.

The Company periodically reviews its inventories and makes a provision as necessary to appropriately value goods that are obsolete, have quality issues, or are damaged. The amount of the provision is equal to the difference between the cost of the inventory and its net realizable value based upon assumptions about product quality, damages, future demand, selling prices, and market conditions. If changes in market conditions result in reductions in the estimated net realizable value of its inventory below its previous estimate, the Company would decrease its basis in the inventory in the period in which it made such a determination.

The purchase price of an acquisition is measured as the aggregate of the fair value of the consideration transferred including the acquisition-date fair value of the Company’s previously held equity interests. The purchase price is allocated to the fair values of the tangible and intangible assets acquired and liabilities assumed, with any excess recorded as goodwill. These fair value determinations require judgment and may involve the use of significant estimates and assumptions. The purchase price allocation may be provisional during a measurement period of up to one year to provide reasonable time to obtain the information necessary to identify and measure the assets acquired and liabilities assumed. Any such measurement period adjustments are recognized in the period in which the adjustment amount is determined. Transaction costs associated with the acquisition are expensed as incurred.

Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the assets acquired and liabilities assumed. Goodwill is not amortized but is evaluated for impairment annually or more frequently if indicators of impairment are present or changes in circumstances suggest that impairment may exist. The Company has one reporting unit and management evaluates the carrying value of the Company’s goodwill annually at the end of its fiscal year or whenever events or changes in circumstances indicate that an impairment may exist.

When testing goodwill for impairment, management has the option of first performing a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as the basis to determine if it is necessary to perform a quantitative goodwill impairment test. In performing the qualitative assessment, management considers the extent to which unfavorable events or circumstances identified, such as changes in economic conditions, industry and market conditions or company specific events, could affect the comparison of the reporting unit’s fair value with its carrying amount. If management concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, management is required to perform a quantitative impairment test.

Quantitative impairment testing for goodwill is based upon the fair value of a reporting unit as compared to its carrying value. Under a quantitative impairment test, management will make certain judgments and assumptions in allocating assets and liabilities to determine carrying values for our reporting unit. The impairment loss recognized would be the difference between a reporting unit’s carrying value and fair value in an amount not to exceed the carrying value of the reporting unit’s goodwill.

Testing goodwill for impairment requires management to estimate fair values of reporting units using significant estimates and assumptions. The assumptions made will impact the outcome and ultimate results of the testing. Management will use industry accepted valuation models and set criteria that are reviewed and approved by various levels of management and, in certain instances, we will engage independent third-party valuation specialists for advice.

The key estimates and factors used in the valuation models would include revenue growth rates and profit margins based on our internal forecasts, our specific weighted-average cost of capital used to discount future cash flows, and comparable market multiples for the industry segment, when applicable, as well as our historical operating trends. Certain future events and circumstances, including deterioration of market conditions, higher cost of capital, a decline in actual and expected consumer consumption and demands, could result in changes to these assumptions and judgments. A revision of these assumptions could cause the fair values of the reporting units to fall below their respective carrying values, resulting in a non-cash impairment charge. Such charge could have a material effect on the consolidated financial statements.

Intangible assets are composed of developed technology, customer relationships and trademarks. At initial recognition, intangible assets acquired in a business combination are recognized at their fair value as of the date of acquisition. Following initial recognition, intangible assets are carried at cost less accumulated amortization and impairment losses, if any, and are amortized on a straight-line basis over the estimated useful life of the asset. We assess the impairment of intangible assets whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If necessary, we will use an industry accepted valuation model to estimate the fair value of the intangible assets. The fair value calculation requires significant judgments in determining both the assets’ estimated cash flows potentially the appropriate discount and royalty rates applied to those cash flows to determine fair value. Variations in economic conditions or a change in general consumer demands, operating results estimates or the application of alternative assumptions could produce significantly different results. If these assumptions differ materially from future results, we may record impairment charges in the future.

Property and equipment is stated at cost less accumulated depreciation. Repair and maintenance costs are expensed as incurred. Depreciation commences when an asset is ready for its intended use. Depreciation is recorded on a straight-line basis over each asset’s estimated useful life. Leasehold improvements are depreciated on a straight-line basis over the lesser of the length of the lease and the estimated useful life of the improvement.

Long-lived assets, including intangible assets with finite lives, held for use are evaluated for impairment when the occurrence of events or a change in circumstances indicates that the carrying value of the assets may not be recoverable as measured by comparing their carrying value to the estimated undiscounted future cash flows generated by their use and eventual disposition. Impaired assets are recorded at fair value, determined principally by discounting the future cash flows expected from their use and eventual disposition. Reductions in asset values resulting from impairment valuations are recognized in income in the period that the impairment is determined.

Prior to the adoption of ASU No. 2016-02, Leases (“ASC 842”), the Company recognized rent expense for operating leases on a straight‑line basis (including the effect of reduced or free rent and rent escalations) over the lease term. The difference between the cash paid to the landlord and the amount recognized as rent expense on a straight‑line basis was recognized as an adjustment to deferred rent in the consolidated balance sheets. Cash reimbursements received from landlords for leasehold improvements and other cash payments received from landlords as lease incentives were recorded as an asset and depreciated using the straight‑line method over the lease term as an offset to rent expense.

fiscal 2021, operating and finance lease liabilities are recognized at the lease commencement date based on the present value of the fixed lease payments using the Company’s incremental borrowing rates for its population of leases. The Company uses an incremental borrowing rate to determine the present value of lease payments as the rate implicit in the lease is generally not readily determinable. The Company’s incremental borrowing rate is the rate of interest that it would have to pay to borrow an amount equal to the lease payments, on a collateralized basis and in a similar economic environment over a similar term.

The Company determines if an arrangement is or contains a lease at inception. This determination depends on whether the arrangement conveys the right to control the use of an explicitly or implicitly identified asset for a period of time in exchange for consideration. Control of an underlying asset is conveyed if the Company obtains the right to direct the use of and obtains substantially all of the economic benefits from using the underlying asset.

As a result of the adoption of the new accounting standard, the Company elected transition-related practical expedients as accounting policies which allowed it to not reassess, as of the adoption date, (1) whether any expired or existing contracts are or contain leases, (2) the classification of any expired or existing leases, and (3) if previously capitalized initial direct costs qualify for capitalization under ASC 842. The Company elected the practical expedient option to not separate lease and non-lease components for all of its leases, and also elected the short-term lease recognition exemption that keeps leases with an initial term of 12 months or less excluded from balance sheet capitalization. This results in recognizing those lease payments in the consolidated statements of operations on a straight-line basis over the lease term. Related operating and finance lease right-of-use assets are recognized based on the initial present value of the fixed lease payments, reduced by cash payments received from landlords as lease incentives, plus any prepaid rent and other direct costs from executing the leases. Amortization of both operating and finance lease right-of-use assets is performed on a straight-line basis and recorded as part of rent expense in cost of goods sold and selling, general and administrative expenses on the consolidated statements of operations. The interest expense amortization component of the finance lease liabilities is recorded within interest expense on the consolidated statements of operations.

On September 14, 2021, the Company issued an aggregate of $750 million in principal amount of its 1.25% Convertible Senior Notes due 2026 (the “Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The Notes were issued pursuant to, and are governed by, an indenture (the “Indenture”), dated as of September 14, 2021, between the Company and U.S. Bank National Association, as trustee (the “Trustee”). The Company accounts for the Notes under Accounting Standards Codification (“ASC”) ASC 470-20 - Debt with Conversion and Other Options and Derivatives and Hedging—Contracts in Entity's Own Equity (“ASU 2020-06”), which the Company early adopted in the first quarter of 2021 concurrent with the issuance of the Notes. The Company records the Notes as a long-term liability at face value net of issuance costs. If any of the conditions to the convertibility of the Notes is satisfied, or the Notes become due within one year, then the Company may be required under applicable accounting standards to reclassify the carrying value of the Notes as a current, rather than a long-term liability. Refer to Note 10—Long-term Debt for further detail.

Capped call transactions cover the aggregate number of shares of the Company’s common stock that will initially underlie the Notes, and generally reduce potential dilution to the Company’s common stock upon any conversion of Notes and/or offset any cash payments the Company may make in excess of the principal amount of the converted Notes, as the case may be, with such reduction and/or offset subject to a cap, based on the cap price of the capped call transactions. The Company determined that the freestanding capped call option contracts qualify as equity under the accounting guidance on indexation and equity classification, and recognized the contract by recording an entry to “Additional paid-in capital” (“APIC”) in stockholders’ equity in its Consolidated Balance Sheet. The Company also determined that the capped call option contracts meet the definition of a derivative under ASC 815 — Derivatives and Hedging (“ASC 815”), but are not required to be accounted for as a derivative as they meet the scope exception outlined in ASC 815. The capped call options are recorded in APIC and not remeasured.

Issuance costs related to our Notes offering were capitalized and offset against proceeds from the Notes. Issuance costs consist of legal and other direct costs related to the issuance of the Notes and are amortized to interest expense over the term of the Notes. Refer to Note 10 – Long-term Debt for further detail.

During October 2020, in connection with Vesper’s initial public offering, the Company issued 15,333,333 warrants to purchase shares of the Company’s common stock at $11.50 per share (the “Public Warrants”). Simultaneously, with the consummation of Vesper’s initial public offering, the Company issued 9,333,333 warrants to purchase shares of the Company’s common stock at $11.50 per share (the “Private Placement Warrants”), to BLS Investor Group LLC (the “Sponsor”).

On November 3, 2021 all of the Public Warrants that were outstanding were redeemed (the “Redemption Date”). As of December 31, 2022 and 2021, no Public Warrants were outstanding and approximately 7 million Private Placement Warrants remain outstanding. As of December 31, 2022 the Private Placement Warrants are measured at fair value using a Monte Carlo simulation because these warrants are not subject to redemption if the reference value of the common stock, as defined, is between $10.00 and $18.00 per share. The Private Placement Warrants are classified as a Level 3 financial instruments as of December 31, 2022. The Private Placement Warrants expire five years after the Business Combination.

The Company classified the Public Warrants and currently classifies the Private Placement Warrants as liabilities on its Consolidated Balance Sheets as these instruments are precluded from being indexed to our own stock given the terms allow for a settlement adjustment that does not meet the scope of the fixed-for-fixed exception in ASC 815, Derivatives and Hedging. In certain events outside of the Company’s control, the Private Placement Warrant holders are entitled to receive cash while in certain scenarios the holders of the Company’s common stock are not entitled to receive cash or may receive less than 100% of any proceeds in cash, which precludes these instruments from being classified within equity pursuant to ASC 815-40. The Public and Private Placement Warrants were initially recorded at fair value on the date of the Business Combination and are subsequently adjusted to fair value at each subsequent reporting date. Changes in the fair value of these instruments are recognized within change in fair value of warrant liabilities in the Company’s Consolidated Statements of Comprehensive Income (Loss).

In addition to the consideration paid at the closing of the Business Combination, the former stockholders of Hydrafacial received contingent consideration in the form of an aggregate of 7.5 million shares of the Company’s Class A Common Stock (the “Earn-out Shares”) as a result of the Company’s completion of the acquisitions of four target businesses, as contemplated by the Merger Agreement, in June and July 2021 that were identified by Hydrafacial. With the closing of these four distributor acquisitions in Australia, France, Germany and Mexico, the 7.5 million Earn-out Shares were earned and subsequently issued on July 15, 2021.

The Company accounted for the Earn-out Shares liability as contingent consideration and recorded an Earn-out Shares liability for the Earn-out Shares in accordance with ASC 480 – Distinguishing Liabilities from Equity. The liability was included as part of the consideration transferred in the Business Combination and was recorded at its then current fair value. The Earn-out Shares liability was recorded at fair value and remeasured at the end of each reporting period, with the corresponding gain or loss recorded in the Company’s Consolidated Statements of Comprehensive Income (Loss) as change in the fair value of earn-out shares liability.

Net sales consist of the sale of products to retail and wholesale customers through e-commerce and distributor sales. The Company generates revenue through manufacturing and selling Hydrafacial Delivery Systems (“Delivery Systems”). In conjunction with the sale of Delivery Systems, the Company also sells its serum solutions and consumables (collectively “Consumables”). Original Consumables are sold solely and exclusively by the Company (and from authorized retailers) and are available for purchase separately from the purchase of Delivery Systems. For both Delivery Systems and Consumables, revenue is recognized upon transfer of control to the customer, which generally takes place at the point of shipment.

The Company distributes products to customers both through national and international retailers as well as direct-to-consumers through its e-commerce and store channels. The Company sells to direct customers, including non-corporate customers (such as spas and dermatologist offices), corporate customers, and international distributors. For non-corporate customers, a contract exists when the customer initiates an order by submitting a purchase request. Such requests are accepted by the Company upon issuance of a corresponding invoice. For corporate customers, a contract exists when the customer submits a purchase order and is accepted upon issuance of a subsequent invoice. For distributors, a customer submits an order request which is processed in the system by a sales representative. This is also considered accepted upon the subsequent

Revenue is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for the sale of its products which is determined based upon the sales price per the invoice or contract. Discounts applied to invoices are not associated with future purchases and solely relate to the product invoiced. As a result, the invoice and transaction price are recorded net of any discounts.

The Company’s sales terms for its Delivery Systems allow for the right of return within 30 days, subject to a restocking fee. Estimates for variable consideration, which relate to sales returns associated with Delivery Systems, are based on the expected amount the Company will be entitled to receive, subject to constraint, and is recorded as a reduction against net sales. Sales returns are estimated based on historical sales and returns data and have not significantly impacted net sales because sales returns are not material.

The Company also has a loyalty program that allows members to receive points based on qualifying Consumable purchases that may be redeemed as a discount on future consumable purchases. This customer option is a material right and, accordingly, represents a separate performance obligation to the customer. The related loyalty program deferred revenue included in other accrued expenses on the consolidated balance sheet was approximately $0.8 million and $1.2 million as of December 31, 2021 and 2022, respectively.

In addition, during fiscal 2022 the Company provided certain customers with the option to trade-in their existing Delivery System and apply the fair value of their old Delivery System towards the transaction price of the Company’s new Syndeo Delivery System. The Company determined that the trade-in is viewed as a marketing offer due to the fact that it does not constitute the Company’s customary business practice and was not offered at contract inception. Therefore, the trade-in is accounted for under ASC 606 and represents a type of noncash consideration, which the Company measures at its estimated fair value. The estimated fair value represents the estimated selling price, less the cost to refurbish the inventory and the expected margin to be earned on the refurbishment, along with the expected margin to be earned on the selling effort. The estimated selling price is determined based on the Company’s historical experience of reselling refurbished Delivery Systems. The total value of these refurbished Delivery Systems included in inventory as of December 31, 2022 was $8.8 million.

Payment terms vary by customer but typically provide for the customer to pay within 30 to 120 days; however, the Company provides an option for qualified customers to pay for Delivery Systems over 12 monthly installments. Therefore, customer payment terms are for 12 months or less and do not include significant financing components. The Company performs credit evaluations of customers and evaluates the need for allowances for potential credit losses based on historical experience, as well as current and expected general economic conditions.

The Company’s cost of sales consists of Delivery Systems and Consumables product costs, including the cost of materials, labor costs, overhead, depreciation and amortization of developed technology, shipping and handling costs, and the costs associated with excess and obsolete inventory. As the Company launches new products and expand presence internationally, the Company expects to incur higher cost of sales as a percentage of sales because we have not yet achieved economies of scale with these items.

Selling and marketing expense consists of personnel-related expenses, sales commissions, travel costs, and advertising expenses incurred in connection with the sale of our products. The Company intends to continue to invest in sales and marketing capabilities in the future and expect this expense to increase in absolute dollars in future periods as it releases new products, grow our global footprint, and drive consumer demand in the ecosystem. Selling and marketing expense as a percentage of total revenue may fluctuate from period to period based on total revenue and the timing of investments in sales and marketing functions as these investments may vary in scope and scale over future periods.

Advertising costs are expensed in the period in which they are incurred. Total advertising costs, included in selling and marketing expenses on the Consolidated Statements of Comprehensive Income (Loss), were $3.8 million, $3.2 million and $3.3 million for each of the three years ending December 31, 2022, 2021, and 2020 respectively.

Research and development expense primarily consists of personnel-related expenses, tooling and prototype materials, technology investments, and other expenses incurred in connection with the development of new products and internal technologies. The Company expects research and development expenses to increase in absolute dollars in future periods and vary from period to period as a percentage of total revenue, as the Company plans to continue to innovate and invest in new technologies and to enhance existing technologies to fuel future growth as a category creator.

General and administrative expense includes personnel-related expenses, professional fees, credit card and wire fees and facilities-related costs primarily for our executive, finance, accounting, legal, human resources, and IT functions. General and administrative expense also includes fees for professional services principally comprising legal, audit, tax and accounting services and insurance.

The Company expects to continue to incur additional general and administrative expenses as a result of operating as a public company, including expenses related to compliance and reporting obligations of public companies, and increased costs for insurance, investor relations expenses, and professional services. In addition, the Company expects to continue to incur additional IT expenses as the Company scales and enhances its e-commerce, digital and data utilization capabilities. As a result, the Company expects that our general and administrative expenses will increase in absolute dollars in future periods and vary from period to period as a percentage of revenue.

Interest expense consists of interest accrued on the Company’s Convertible Senior Notes and amortization of debt issuance costs relating to the Notes. The Notes mature on October 1, 2026 and accrue interest at a rate of 1.25% per annum. Debt issuance costs are being amortized over the term of the Notes using the effective interest method. If the Notes are repurchased, redeemed, or converted prior to the maturity date, the interest on the Notes would no longer be accrued and the amortization of debt issuance costs would be accelerated. The Company expects interest expense to increase in absolute dollars as the Company grows internationally and obtains more financing to support such growth. Interest expense as a percentage of revenue will fluctuate period to period along with fluctuations in interest rates, which is not related to normal business operations.

In accordance with ASC 815-40 – Contracts in Entity's Own Equity, the Company’s Public and Private Placement Warrants are accounted for as liabilities in the Consolidated Balance Sheets and measured at fair value at inception and on a recurring basis, with changes in fair value presented within change in fair value of warrant liabilities in the Company’s Consolidated Statements of Comprehensive Income (Loss). There were no Public Warrants outstanding as of December 31, 2022. The value of the Private Placement Warrants was determined at year end using the Monte Carlo simulation model. Changes around share price volatility and assumptions and inputs used in the Monte Carlo model can result in an increase or decrease in fair value which can substantially impact the outstanding liability and the change in fair value of warrant liabilities. Changes in fair value of warrant liabilities as a percentage of revenue will fluctuate period to period along with fluctuations in fair value, which is not related to normal business operations.

In accordance with ASC 480 – Distinguishing Liabilities from Equity, the Company accounted for its Earn-out Shares liability as contingent consideration and recorded an Earn-out Shares liability for the Earn-out Shares. The Earn-out Shares liability was recorded at fair value and remeasured at the end of each reporting period, with the corresponding gain or loss

Foreign currency transaction gains and losses are generated by settlements of intercompany balances and invoices denominated in other currencies other than the reporting currency. Foreign currency gains and losses as a percentage of revenue will fluctuate period to period along with fluctuations in exchange rates, which is not related to normal business operations.

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets (DTA)s and deferred tax liabilities (DTL)s for the expected future tax consequences of events that have been included in the financial statements. Under this method, we determine DTAs and DTLs on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on DTAs and DTLs is recognized in income in the period that includes the enactment date.

The Company recognizes DTAs to the extent that it believes these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, carryback potential if permitted under the tax law, and results of recent operations. A valuation allowance is established, when necessary, to reduce deferred tax assets to the amount that is more likely than not to be realized based on currently available evidence. If the Company determines that it would be able to realize our DTAs in the future in excess of the net recorded amount, it would make an adjustment to the DTA valuation allowance, which would reduce the provision for income taxes.

The Company would record uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) it determined whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. If any, the Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense.

The functional currency for each entity included in these consolidated financial statements that is domiciled outside of the United States is generally the applicable local currency. Assets and liabilities of each foreign entity are translated into U.S. dollars at the exchange rate in effect on the balance sheet date. Net revenue and expenses are translated at the average rate in effect during the period. Unrealized translation gains and losses are recorded as a foreign currency translation adjustment, which is included in other comprehensive income or loss, which is a component of accumulated other comprehensive income or loss included in stockholders’ equity.

Transactions between the parent company and its foreign subsidiaries are denominated in US Dollars. Accordingly, amounts due to or from the parent company are remeasured from local currency to its US Dollar equivalent on the balance sheet date. This remeasurement is recorded as a foreign currency transaction gain or loss in the consolidated statements of comprehensive income.

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company primarily maintains its operating cash balance with a major financial institution. At times, cash balances may be in excess of Federal Deposit Insurance Corporation insurance limits. The Company has not experienced any losses in these accounts and does not believe it is exposed to any significant credit risk in this area. Accounts receivable are unsecured and the Company is at risk to the extent such amounts become uncollectible. Concentration of credit risk with respect to accounts receivable is generally mitigated by the Company performing ongoing credit evaluations of its customers.

Stock-based compensation is accounted for under FASB ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). The Company accounts for all stock-based compensation transactions using a fair-value method and recognizes the fair value of each award as an expense over the service period. The Company estimates the fair value of stock options granted using the Black-Scholes option-pricing model. The use of the Black-Scholes model requires a number of estimates, including the expected option term, the expected volatility in the price of the Company’s common stock, the risk-free rate of interest and the dividend yield on the Company’s common stock. The fair value of the Company’s restricted stock units is the closing price of the Company’s common stock on the grant date. The fair value of the Company’s performance-based restricted stock units is estimated using a Monte Carlo simulation model. The consolidated financial statements include amounts that are based on the Company’s best estimates and judgments. The Company classifies compensation expense related to these awards in the Consolidated Statements of Comprehensive Income (Loss) based on the department to which the recipient reports. The Company’s policy is to account for forfeitures in period that they occur.

Earnings per share is calculated using the weighted-average number of common and exchangeable shares outstanding during the period. Exchangeable shares are the equivalent of common shares in all material respects. Diluted earnings per share is calculated by dividing net income available to stockholders for the period by the diluted weighted-average number of shares outstanding during the period. Diluted earnings per share reflects the potential dilution from common shares issuable through stock options, performance-based restricted stock units that have satisfied their performance factor, restricted shares, and restricted stock units using the treasury stock method.

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:

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy.

The fair value of the Notes that are recorded at historical cost was $567 million as of December 31, 2022, and was determined using the last trade price in active markets. With the exception of the Company’s Notes, the fair value of the Company’s assets and liabilities that are recorded at historical amounts and that qualify as financial instruments under ASC 820, Fair Value Measurement, approximates the carrying amounts represented in the Company’s Consolidated Balance Sheets, primarily due to their short-term nature.

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU 2021-08, Business Combinations (Topic 805), which primarily relates to the accounting for contract assets and contract liabilities from contracts with customers in a business combination. The standard will be effective for annual reporting periods beginning after December 31, 2022, including interim reporting periods within those periods, with early adoption permitted. We are currently evaluating the impact of adopting this new accounting guidance on our consolidated financial statements.
