Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Business Combination The Business Combination was accounted for as a reverse recapitalization in accordance with 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. 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. Accounts Receivable Accounts receivable primarily arise out of product purchases by customers and from various distribution channels. Typical payment terms provide that customers pay within less than a year 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, and other qualitative factors. 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. During the quarter ended December 31, 2023, the Company determined with respect to Syndeo devices, to market and sell Syndeo 3.0 devices exclusively, and as such, the Company designated all Syndeo 1.0 and 2.0 builds on-hand as obsolete, resulting in an inventory write-down of $19.6 million during the year ended December 31, 2023. Refer to Note 18 – Restructuring Charges for further detail. 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 and 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. Leased Property and Equipment Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. 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 excludes right-of-use assets and lease liabilities for leases with an initial term of 12 months or less from the balance sheet,and combines lease and non-lease components for property leases, which primarily relate to ancillary expenses such as common area maintenance expenses, property taxes, property insurance, and management fees. The Company determines if an arrangement is a lease at inception by assessing whether it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Renewal and termination options are included in the lease term when it is reasonably certain that the Company will exercise the option. Certain of these leases include escalation clauses that adjust rental expense to reflect changes in price indices, as well as renewal and termination options. Operating lease costs are recognized on a straight-line basis over the lease term. Impairment of Long-lived Assets Long-lived assets, including intangible assets with finite lives and right-of-use assets, 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. 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, 2023 and 2022, no Public Warrants were outstanding and approximately 7 million Private Placement Warrants remain outstanding. As of December 31, 2023 and 2022, the Private Placement Warrants are measured at fair value using a Monte Carlo simulation model 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, 2023 and 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. 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 202 6 (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 ad opted 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 9— 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 Sheets. 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 using the effective interest method. Refer to Note 9 – Long-term Debt for further detail. 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 its patented hydradermabrasion delivery systems (“Delivery Systems”). In conjunction with the sale of Delivery Systems, the Company also sells single-use tips, solutions, and serums used to provide a Hydrafacial treatment (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 and the estimated fair market value of any non-cash consideration, if applicable. 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 generally 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 two 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 Sheets was approximately $1 million as of December 31, 2023 and 2022. In addition, during the fiscal years 2023 and 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 a Syndeo device, the Company’s current generation Delivery System (“Syndeo”). 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 Company recognized revenue based on the estimated fair value of such Delivery Systems for the fiscal years ended 2023 and 2022 of approximately $17 million and $9 million, respectively. Payment terms vary by customer but typically provide for the customer to pay within less than a year; however, the Company provides options for qualified customers through third party financing companies, generally without recourse to the Company, or through internal financing to pay for Delivery Systems over 12 monthly installments or less. Under certain limited arrangements, which are not material, the customer’s receivable balance is with recourse whereby we are responsible for repaying the financing company should the customer default. 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 does not evaluate contracts of one year or less for the existence of a significant financing component. 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. Selling and Marketing Expense Selling and marketing expense consists of personnel-related expenses, sales commissions, travel costs, training, and advertising expenses incurred in connection with the sale of our products. Advertising costs are expensed in the period in which they are incurred. Total advertising costs were $2.3 million, $3.8 million and $3.2 million for the years ending December 31, 2023, 2022, and 2021 respectively. Research and Development Expense 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. General and Administrative Expense General and administrative expenses include personnel-related expenses, professional fees, credit card and wire fees and facilities-related costs primarily for our executive, corporate affairs, finance, accounting, legal, human resources, and information technology (“IT”) functions. General and administrative expense also includes fees for professional services principally comprising legal, audit, tax and accounting services and insurance. Interest Expense Interest expense primarily consists of interest accrued on the Company’s 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 for the portion of the Notes which are repurchased, redeemed, or converted. Interest Income Interest income consists of interest earned from investments in money market funds that the Company classifies as cash equivalents. 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, 2023 and 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. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets (“DTAs”) and deferred tax liabilities (“DTLs”) for the expected future tax consequences of events that have been included in the financial statements. Under this method, it determines 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 records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) it determines 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 Compan |
