(1) Under the Tax Cuts and Jobs Act of 2017, research and development costs are no longer fully deductible and are required to be capitalized and amortized for U.S. tax purposes effective January 1, 2022. The mandatory capitalization requirement increases our gross deferred tax assets, which are fully offset by the valuation allowance.

In assessing the realizability of deferred tax assets, the Company evaluates all available positive and negative evidence by considering whether it is more likely than not that some portion or all of the deferred tax assets will not be recognized. The ultimate realization of deferred tax assets is dependent upon future taxable income, future reversals of existing taxable temporary difference, taxable income in carryback years and tax-planning strategies. The Company believes it is more likely than not that the deferred tax assets in the U.S. will not be realized; accordingly, a valuation allowance has been established against our U.S. deferred tax assets. The net change in the valuation allowance for the years ended December 31, 2023 and December 31, 2022 was an increase of $26.5 million and an increase of $80.3 million, respectively.

As of December 31, 2023 and 2022, the Company has a net operating loss carryforward of $871.3 million and $827.6 million for federal tax purposes, respectively, and $817.5 million and $770.0 million for state tax purposes, respectively. If not utilized, these losses will expire beginning in 2024 for state tax purposes. However, beginning in tax year 2018 and forward, the Federal law has changed such that net operating losses generated after December 31, 2017 may be carried forward indefinitely. Accordingly, $168.2 million of the federal net operating losses will begin to expire in 2032. However, $703.1 million of the federal net operating losses will not expire.

As of December 31, 2023 and 2022, the Company has a credit carryforward of $4.3 million and $2.0 million for federal tax purposes, respectively, and $1.0 million and $1.0 million for state tax purposes, respectively. If not utilized, these credits will expire beginning in 2041 for federal tax purposes and do not expire for state tax purposes.

The Tax Reform Act of 1986 limits the use of net operating losses and tax credit carryforwards in certain situations where changes occur in the stock ownership of a company. During 2019, the Company analyzed whether any of the reported net operating losses would be limited because of these rules. Based on the analysis the Company believes $3.3 million of the Federal and $2.1 million of California net operating losses will not be available to offset future taxable income because of the limitation. The reported net operating losses have been adjusted based on this analysis.

The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company is subject to examination by federal, state and local, jurisdictions, where applicable. As of December 31, 2023 and 2022, all years generally remain open to examination. Additionally, net operating loss

carryforwards are subject to examination by the Internal Revenue Service and the California Franchise Tax Board for up to three and four years, respectively, after utilization.

Uncertain Income Tax Positions

The following table reflects the changes to the Company's unrecognized tax benefits (in thousands):


	December 31,
	2023		2022
Unrecognized tax benefits beginning balance	$	1,525	$	—
Increases related to current year tax positions	531		563
Increases related to prior year tax positions	622		962
Unrecognized tax benefits ending balance	$	2,678	$	1,525

As of December 31, 2023 and 2022, the Company had unrecognized tax benefits of $2.7 million and $1.5 million, respectively, none of which, if recognized, would favorably impact the Company’s effective tax rate. The unrecognized tax benefits relate to federal and state research and development credits. The Company's policy is to include interest and penalties as a component to the statement of operations, however there were no associated interest and penalties during the years ended December 31, 2023 and 2022. The Company estimates that there will be no material changes in its uncertain tax positions in the next 12 months.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of expenses during the reporting period. Significant items subject to such estimates and assumptions include those related to revenue recognition, including the returns reserve, standalone selling price related to consignment revenue transactions, valuation of inventory, software development costs, stock-based compensation, incremental borrowing rates related to lease liability, valuation of deferred taxes, and other contingencies. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ from those estimates.

Net Loss per Share Attributable to Common Stockholders

The Company follows the two-class method when computing net loss per common share when shares are issued that meet the definition of participating securities. The two-class method determines net loss per common share for each class of common stock and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income (loss) available or attributable to common stockholders for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed.

The Company’s convertible senior notes are participating securities as they give the holders the right to receive dividends if dividends or distributions declared to the common stockholders is equal to or greater than the last reported sale price of the Company’s common stock on the trading day immediately preceding the ex-dividend date for such dividend or distribution as if the instruments had been converted into shares of common stock. No undistributed earnings were allocated to the participating securities as the contingent event is not satisfied as of the reporting date.

For periods in which the Company reports net losses, diluted net loss per common share attributable to common stockholders is the same as basic net loss per common share attributable to common stockholders, because potentially dilutive common shares and assumed conversion of the convertible senior notes are not assumed to have been issued within the calculation, if their effect is anti-dilutive.

Segments

The Company has one operating segment and one reportable segment as its chief operating decision maker, who is its Chief Executive Officer, reviews financial information on a consolidated basis for purposes of allocating resources and evaluating financial performance. All long-lived assets are located in the United States and substantially all revenue is attributed to consignors and buyers based in the United States.

Revenue Recognition

The Company generates revenue from the sale of pre-owned luxury goods through its online marketplace and retail stores. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that include products and services that are capable of being distinct and accounted for as separate performance obligations as described below. The transaction price requires an allocation across consignment services, sales of Company-owned inventory, and shipping services. Estimation is required in the determination of the services' stand-alone selling price (“SSP”).

Consignment Revenue

The Company provides a service to sell pre-owned luxury goods on behalf of consignors to buyers through its online marketplace and retail stores. The Company retains a percentage of the proceeds received as payment for its consignment service, which the Company refers to as its take rate. SSP is estimated using observable stand-alone consignment sales which are conducted without shipping services. The Company reports consignment revenue on a net basis as an agent and not the gross amount collected from the buyer. Title to the consigned goods remains with the consignor until transferred to the buyer upon purchase of the consigned goods and expiration of the allotted return period. The Company does not take title of consigned goods at any time except in certain cases where returned goods become Company-owned inventory.

The Company recognizes consignment revenue upon purchase of the consigned good by the buyer as its performance obligation of providing consignment services to the consignor is satisfied at that point. Consignment revenue is recognized net of estimated returns, cancellations, buyer incentives and adjustments. The Company recognizes a returns reserve based on historical experience, which is recorded in other accrued and current liabilities on the balance sheets (see Note 5). Sales tax assessed by governmental authorities is excluded from revenue.

Certain transactions provide consignors with a material right resulting from the tiered consignor commission plan. Under this plan, the amount an individual consignor receives for future sales of consigned goods may be dependent on previous consignment sales for that consignor within his/her consignment period. Accordingly, in certain consignment transactions, a small portion of the Company’s consignment revenue is allocated to such material right using the portfolio method and recorded as deferred revenue, which is recorded in other accrued and current liabilities on the balance sheets. The impact of the deferral has not been material to the financial statements.

The Company also generates subscription revenue from monthly memberships allowing buyers early access to shop for luxury goods. The buyers receive the early access and other benefits over the term of the subscription period, which represents a single stand-ready performance obligation. Therefore, the subscription fees paid by the buyer are recognized over the monthly subscription period. Subscription revenue was not material in 2023, 2022, and 2021.

Direct Revenue

The Company generates direct revenue from the sale of Company-owned inventory. The Company recognizes direct revenue on a gross basis upon shipment of the purchased good to the buyer as the Company acts as the principal in the transaction. SSP is estimated using observable stand-alone sales of Company-owned inventory which are conducted without shipping services, when available, or a market assessment approach. Direct revenue is recognized net of estimated returns, buyer incentives and adjustments. Sales tax assessed by governmental authorities is excluded from revenue. Cost of direct revenue is also recognized upon shipment to the buyer in an amount equal to that paid to the consignor from the original consignment sale, an amount equal to that paid as a direct purchase from a third party, or the lower of cost of the inventory purchased and its net realizable value.

Shipping Services Revenue

The Company provides a service to ship purchased items to buyers and a service to ship items from buyers back to the Company. The Company determines itself to be the principal in this arrangement. The Company charges a fee to buyers

for this service and has elected to treat shipping and handling activities performed as a separate performance obligation. For shipping services revenue, the Company's SSP is estimated using a market approach considering external and internal data points on the stand-alone sales price of the shipping service. All outbound shipping and handling costs for buyers are accounted for as cost of shipping services and recognized as the shipping activity occurs. The Company also generates shipping services revenue from the shipping fees for consigned products returned by buyers to the Company within policy. The Company recognizes shipping revenue and associated costs over time as the shipping activity occurs, which is generally one to three days after shipment.

Incentives

Incentives, which include platform-wide discounts and buyer incentives, may periodically be offered to buyers. Platform-wide discounts are made available to all buyers on the online marketplace. Buyer incentives apply to specific buyers and consist of coupons or promotions that offer credits in connection with purchases on the Company’s platform, and do not impact the commissions paid to consignors. These are treated as a reduction of consignment revenue and direct revenue. Additionally, the Company periodically offers commission exceptions to the standard consignment rates to consignors to optimize its supply. These are treated as a reduction of consignment revenue at the time of sale. The Company may offer a certain type of buyer incentive in the form of site credits to buyers on current transactions to be applied towards future transactions, which are included in other accrued and current liabilities on the balance sheets.

Contract Liabilities

The Company’s contractual liabilities primarily consist of deferred revenue for material rights primarily related to the tiered consignor commission plan, which are recognized as revenue using a portfolio approach based on the pattern of exercise, and certain buyer incentives. Contract liabilities are recorded in other accrued and current liabilities on the balance sheets and are generally expected to be recognized within one year. Contract liabilities were immaterial as of December 31, 2023 and December 31, 2022.

Cost of Revenue

Cost of consignment revenue consist of credit card fees, packaging, customer service personnel-related costs, website hosting services, and consignor inventory adjustments relating to lost or damaged products. Cost of direct revenue consists of the cost of goods sold, credit card fees, packaging, customer service personnel-related costs, website hosting services, and inventory adjustments. Cost of shipping services revenue consists of the outbound shipping and handling costs to deliver purchased items to buyers, the shipping costs for consigned products returned by buyers to the Company within policy, and an allocation of the credit card fees associated with the shipping fee charged.

Marketing

Marketing expense is comprised of the cost of acquiring new consignors and buyers for our online platform and physical stores, including the cost of television, digital and direct mail advertising. Marketing expense also includes personnel-related costs, including stock-based compensation, of employees engaged in these activities. Advertising costs are expensed as incurred and were $48.4 million, $49.0 million, and $46.2 million in 2023, 2022, and 2021, respectively.

Operations and Technology

Operations and technology expense is comprised of costs associated with the authentication, merchandising and fulfillment of goods sold through our online marketplace and retail stores, as well as general information technology expense. The principal component of operations and technology expense is personnel-related costs, including stock-based compensation, of employees engaged in these activities. Operations and technology expense also includes allocated facility and overhead costs, costs related to our retail stores, facility supplies, inbound consignment shipping costs, and depreciation of hardware and equipment, as well as research and development expense for technology associated with managing and improving our operations. In 2023, 2022, and 2021, the Company capitalized proprietary software developments costs of $13.3 million, $15.6 million, and $12.7 million, respectively. As such, operations and technology expense also includes amortization of capitalized technology development costs, which is taken on straight-line basis over three years once the technology is ready for its intended use.

Selling, General and Administrative

Selling, general and administrative expense is principally comprised of the personnel-related costs for employees involved in sales, finance and administration, and includes stock-based compensation expense. Selling, general and

administrative expense also includes allocated facility and overhead costs and professional services, including accounting and legal advisors.

Stock-based Compensation

The Company incurs stock-based compensation expense from stock options, restricted stock units (“RSUs”), performance based restricted stock units (“PSUs”) subject to performance or market conditions, and employee stock purchase plan (“ESPP”) purchase rights. Stock-based compensation expense related to employees and nonemployees is measured based on the grant-date fair value of the awards. The Company estimates the fair value of stock options granted and the purchase rights issued under the ESPP using the Black-Scholes option pricing model. The fair value of RSUs is estimated based on the fair market value of the Company’s common stock on the date of grant, which is determined based on the closing price of the Company’s common stock. Compensation expense is recognized in the statements of operations over the period during which the employee is required to perform services in exchange for the award (the vesting period of the applicable award) using the straight-line method for awards with only a service condition.

To determine the grant-date fair value of the Company's stock-based payment awards for PSUs subject to performance conditions, the quoted stock price on the date of grant is used. The stock-based compensation expense for PSUs with performance conditions is recognized based on the estimated number of shares that the Company expects will vest and is adjusted on a quarterly basis using the estimated achievement of financial performance targets. For PSUs subject to market conditions, the grant-date fair value is determined using the Monte Carlo simulation model which utilizes multiple input variables to estimate the probability that market conditions will be achieved. These variables include the Company's expected stock price volatility over the expected term of the award, the risk-free interest rate for the expected term of the award, and expected dividends. For PSUs with market conditions, the stock-based compensation expense is recognized on a tranche by tranche basis over the requisite service period using the fair value derived from the Monte Carlo simulation model. The compensation expense will be recognized regardless of whether the market condition is ever satisfied, provided the requisite service period is satisfied. For all awards, the Company accounts for forfeitures as they occur.

Cash, Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be cash equivalents. Cash equivalents primarily consist of investments in short-term money market funds.

Restricted cash consists of cash deposited with a financial institution as collateral for the Company’s letters of credit for its facility leases and the Company’s credit cards. The Company had $14.9 million and $0 in restricted cash as of December 31, 2023 and 2022, respectively.

The following table provides a reconciliation of cash, cash equivalents and restricted cash for the year ended December 31, 2023 that sum to the total of the same amounts shown in the statements of cash flows (in thousands):


	December 31, 2023		December 31, 2022		December 31, 2021
Cash and cash equivalents	$	175,709	$	293,793	$	418,171
Restricted cash	14,914		—		—
Total cash, cash equivalents and restricted cash	$	190,623	$	293,793	$	418,171

Accounts Receivable

Accounts receivables are recorded at the amounts billed to buyers and do not bear interest. Accounts receivables result from credit card transactions, the majority of which are settled within two business days.

Inventory, Net

Inventory consists of finished goods arising from goods returned after the title has transferred from the buyer to the Company as well as finished goods from direct purchases from vendors and consignors. The cost of inventory is an amount equal to that paid to the consignor or vendors. Inventory is valued at the lower of cost and net realizable value using the specific identification method and the Company records provisions, as appropriate, to write down obsolete and excess inventory to estimated net realizable value. After the inventory value is reduced, adjustments are not made to increase it from the estimated net realizable value. Additionally, inventory is recorded net of an allowance for shrinkage which represents the risk of physical loss of inventory. Provisions for inventory shrinkage are estimated based on historical

experience and are adjusted based upon physical inventory counts. Provisions to write down inventory to net realizable value and provisions for inventory shrinkage were $9.8 million and $4.1 million during the year end December 31, 2023 and 2022, respectively.

Return reserves, which reduce revenue and cost of sales, are estimated using historical experience. Liabilities for return allowances are included in other accrued and current liabilities on the balance sheets and were $22.2 million as of December 31, 2023 and 2022. Included in inventory on the Company’s balance sheets are assets totaling $5.2 million and $6.1 million as of December 31, 2023 and 2022, respectively, for the rights to recover products from customers associated with its liabilities for return reserves.

Property and Equipment, Net

Property and equipment, net is recorded at cost less accumulated depreciation and amortization. Depreciation and amortization are recorded on a straight-line basis over the estimated useful lives of the respective assets. Repair and maintenance costs are expensed as incurred.

The estimated useful lives of our assets are as follows:


Proprietary software			3 years
Furniture and equipment			3-5 years
Vehicles			5 years
Leasehold improvements			Shorter of lease term or estimated useful life

Software Development Costs

Proprietary software includes the costs of developing the Company’s internal proprietary business platform and automation projects. The Company capitalizes qualifying proprietary software development costs that are incurred during the application development stage. Capitalization of costs begins when two criteria are met: (1) the preliminary project stage is completed and (2) it is probable that the software will be completed and used for its intended function. Such costs are capitalized in the period incurred. Capitalization ceases and amortization begins when the software is substantially complete and ready for its intended use, including the completion of all significant testing. Costs related to preliminary project activities and post-implementation operating activities are expensed as incurred.

Impairment of Long-lived Assets

The carrying amounts of long-lived assets, including right-of-use assets, property and equipment, net and capitalized proprietary software, are periodically reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable or that the useful life is shorter than originally estimated. Recoverability of assets to be held and used is measured by comparing the carrying amount of assets to future undiscounted net cash flows the assets are expected to generate over their remaining life.

If the assets are considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired assets. If the useful life is shorter than originally estimated, the Company amortizes the remaining carrying value over the revised shorter useful life.

Leases

Contracts that have been determined to convey the right to use an identified asset are evaluated for classification as an operating or finance lease. For the Company’s operating leases, the Company records a lease liability based on the present value of the lease payments at lease inception, using the applicable incremental borrowing rate. The Company estimates the incremental borrowing rate by developing its own synthetic credit rating, corresponding yield curve, and the terms of each lease at the lease commencement date. The corresponding right-of-use asset is recorded based on the corresponding lease liability at lease inception, adjusted for payments made to the lessor at or before the commencement date, initial direct costs incurred and any tenant incentives allowed for under the lease. The Company does not include optional renewal terms or early termination provisions unless the Company is reasonably certain such options would be

exercised at the inception of the lease. Operating lease right-of-use assets, current portion of operating lease liabilities, and operating lease liabilities, net of current portion are included on the Company’s balance sheet.

The Company has elected the practical expedients that allows for the combination of lease components and non-lease components and to record short-term leases as lease expense on a straight-line basis on the statements of operations. Variable lease payments are recorded as expense as they are incurred.

The Company has finance leases for vehicles and equipment, and the amounts of finance lease right-of-use assets and finance lease liabilities have been immaterial to date.

Convertible Senior Notes, Net

Prior to the adoption of ASU 2020-06 on January 1, 2022, convertible debt instruments that may be settled in cash or other assets, or partially in cash, upon conversion, were separately accounted for as long-term debt and equity components (or conversion feature). The debt component represented the Company’s contractual obligation to pay principal and interest and the equity component represented the Company’s option to convert the debt security into equity of the Company or the equivalent amount of cash. Upon issuance, the Company allocated the debt component on the basis of the estimated fair value of a similar liability that does not have an associated convertible feature and the remaining proceeds are allocated to the equity component. The bifurcation of the debt and equity components resulted in a debt discount for the aforementioned notes. The Company uses the effective interest method to amortize the debt discount to interest expense over the amortization period which is the expected life of the debt. Following the adoption of ASU 2020-06, there is no bifurcation of the liability and equity components of the 3.00% Convertible Senior Notes due 2025 (the “2025 Notes”) and the 1.00% Convertible Senior Notes due 2028 (the “2028 Notes” and, together with the 2025 Notes, the “Notes”), and the entire principal of the Notes are accounted for as long-term debt.

Capped Call Transactions

In June 2020 and March 2021, in connection with the issuance of its convertible senior notes, the Company entered into Capped Call Transactions (see Note 7). The Capped Call Transactions are expected generally to reduce the potential dilution to the holders of the Company’s common stock upon any conversion of the convertible senior notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted convertible senior notes, with such reduction and/or offset subject to a cap based on the cap price. The capped calls are classified in stockholders’ equity as a reduction to additional paid-in capital and are not subsequently remeasured as long as the conditions for equity classification continue to be met. The Company monitors the conditions for equity classification, which continue to be met as of December 31, 2023.

Debt Issuance Costs

Debt issuance costs, which consist of direct incremental legal, consulting, banking and accounting fees related to the anticipated debt offering, are amortized to interest expense over the estimated life of the related debt based on the effective interest method. The Company presents debt issuance costs on the balance sheets as a direct deduction from the associated debt. The Company adopted ASU 2020-06 as of January 1, 2022 using the modified retrospective method. Prior to the adoption of ASU 2020-06 on January 1, 2022, a portion of debt issuance costs incurred in connection with the convertible senior notes issued in June 2020 and March 2021 was allocated to the equity component and was recorded as a reduction to additional paid in capital and was not amortized to interest expense over the estimated life of the related debt. Following the adoption of ASU 2020-06, the debt issuance costs previously allocated to the equity component of both series of Notes were reclassified to debt. As such, all of the debt issuance costs are recorded as a direct deduction from the related principal debt amounts on the balance sheet, and are all amortized to interest expense over the estimated remaining life of the related debt.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

The effect on deferred tax assets and liabilities of a change in tax rates is recognized in loss in the period of enactment. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

Concentrations of Credit Risks

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, restricted cash and accounts receivable. At times, such amount may exceed federally-insured limits. The Company is monitoring ongoing events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or other companies in the financial services industry or the financial services industry generally. The Company reduces credit risk by placing its cash, cash equivalents, restricted cash and investments with major financial institutions with high credit ratings within the United States. The Company has not experienced any realized losses on cash, cash equivalents and restricted cash to date; however, no assurances can be provided.

As of December 31, 2023 and December 31, 2022, there were no customers that represented 10% or more of the Company’s accounts receivable balance and there were no customers that individually exceeded 10% of the Company’s total revenue for each of the years ended December 31, 2023, 2022, and 2021.

Recently Issued Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures. This new guidance is designed to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker. Additionally, public entities with a single reportable segment must provide all the disclosures required by ASU 2023-07, as well as all existing segment disclosures in accordance with Accounting Standards Codification 280. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis. Early adoption is permitted. The Company expects the adoption of the standard to result in additional segment footnote disclosures. The Company does not expect the adoption of this guidance to have a material impact on our financial statements.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. This new guidance is designed to enhance the transparency and decision usefulness of income tax disclosures. The amendments of this update are related to the rate reconciliation and income taxes paid, requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently assessing the impact that adopting this new accounting standard will have on its financial statements.

Share-Based Payment Arrangement [Abstract]

Share-based Compensation Plans

2019 Equity Incentive Plan

In connection with the Company’s initial public offering, the Company adopted the 2019 Equity Incentive Plan (the “2019 Plan”). The 2019 Plan allows the Company to grant stock options, stock appreciation rights, restricted stock, restricted stock units and performance awards to participants. Subject to the terms and conditions of the 2019 Plan, the initial number of shares authorized for grants under the 2019 Plan is 8,000,000. These available shares increase annually by

an amount equal to the lesser of 8,000,000 shares, 5% of the number of shares of the Company’s common stock outstanding on the immediately preceding December 31, or the number of shares determined by the Company’s board of directors.

The Company’s board of directors approved an increase of shares available for grant under the 2019 Plan by 4,465,083 shares on May 5, 2021, by 4,648,003 shares on February 23, 2022, and by 4,954,409 shares on February 13, 2023.

Activity under the Company’s stock option plan is set forth below:


	Number of Options	Weighted- Average Exercise Price Per Share	Weighted- Average Remaining Contractual Life (years)	Aggregate Intrinsic Value (in thousands)
Balances at December 31, 2022	1,754,776	8.21	4.0	$	1
Options granted	—	—
Options exercised	(8,511)	2.28
Options cancelled	(626,589)	9.04
Balances at December 31, 2023	1,119,676	7.79	4.2	15
Options vested and exercisable— December 31, 2023	1,119,676	7.79	4.2	15

There were no stock options granted in 2023 and in 2022. There was no aggregate intrinsic value of options exercised for the year ended December 31, 2023. The aggregate intrinsic value of options exercised for the years ended December 31, 2022 and 2021 was $5.3 million and $20.5 million, respectively. The aggregate intrinsic value of options exercised is the difference between the fair value of the underlying common stock on the date of exercise and the exercise price for in-the-money stock options.

In February 2022, the Company granted PSUs with financial performance targets to certain employees of the Company. The number of units issued will depend on the achievement of financial metrics relative to the approved performance targets, and can range from 0% to 150% of the target amount. The PSUs are subject to continuous service with the Company and will vest after approximately three years. The PSUs are measured using the fair value at the date of grant. The compensation expense associated with PSUs is recognized based on the estimated number of shares that the Company expects will vest and may be adjusted based on interim estimates of performance against the performance condition. During the year ended December 31, 2023, the Company has not recognized stock-based compensation expense as attainment of financial performance targets is not considered probable.

In March 2023, the Company granted PSUs under the 2019 Plan subject to the achievement of both market and service conditions to certain employees of the Company. The number of units vested will depend on the achievement of approved market conditions and continuous service with the Company. The PSUs are eligible to vest in three tranches over a five-year performance period. The PSUs are measured using the Monte Carlo simulation to obtain the fair value at the date of grant based on the probability that the market conditions will be met. The compensation expense associated with the PSUs is based on the fair value and is recognized over the requisite service period. The compensation expense will be recognized regardless of whether the market condition is ever satisfied, provided the requisite service period is satisfied.

Inducement Grants

In March 2023, the Company granted stock-based awards outside of the 2019 Plan to the Company’s new Chief Executive Officer and the Chief Technology and Product Officer. These awards were granted as inducements material to their commencement of employment and entry into offer letters with the Company, in accordance with Nasdaq Listing Rule 5635(c)(4).

The inducement pool consisted of a total of 3,075,000 shares of the Company's common stock, which includes (a) 1,500,000 shares of PSUs granted to the Chief Executive Officer that are eligible to vest based on market and service conditions in four tranches over a five-year performance period and (b) 1,575,000 shares of RSUs (1,250,000 RSUs to the Chief Executive Officer and 325,000 RSUs to the Chief Technology and Product Officer) generally subject to the same terms and conditions as grants that are made under the 2019 Plan. As of December 31, 2023, the unrecognized expense for the PSUs is $1.3 million and the unrecognized expense for RSUs is $2.0 million.

RSUs

A summary of RSU activity for the year ended December 31, 2023 is as follows:


	Number of Shares	Restricted Stock Units Weighted- Average Grant Date Fair Value		Aggregate Intrinsic Value (in thousands)
Unvested December 31, 2022	11,369,021	$	8.39	$	14,178
Granted	10,863,664	1.62
Vested	(5,098,002)	7.51
Forfeited	(4,439,507)	5.19
Unvested December 31, 2023	12,695,176	$	4.07	$	25,517

Included in the table above for the year ended December 31, 2023 are approximately 1,998,000 PSUs granted and no PSUs forfeited. The weighted average grant date fair value per share of the PSUs granted in the year ended December 31, 2023 was $1.63.

The total fair value as of the respective vesting dates of RSUs that vested during the year ended December 31, 2023 was $9.5 million.

Employee Stock Purchase Plan

In connection with the Company’s initial public offering, the Company adopted the Employee Stock Purchase Plan (the “ESPP”). The Employee Stock Purchase Plan permits employees to purchase shares of common stock during six-month offering periods at a purchase price equal to the lesser of (1) 85% of the fair market value of a share of common stock on the first business day of such offering period and (2) 85% of the fair market value of a share of common stock on the last business day of such offering period. The initial number of shares of common stock that could be issued under the employee stock purchase plan was 1,750,000 shares. These available shares increase by an amount equal to the lesser of 1,750,000 shares, 1% of the number of shares of common stock outstanding on the immediately preceding December 31, or the number of shares determined by the Company’s board of directors.

The Company's board of directors approved an increase in the shares available for grant under the ESPP by 893,016 shares on May 5, 2021, by 929,601 shares on February 23, 2022, and by 990,882 shares on February 13, 2023.

During the years ended December 31, 2023, 2022 and 2021, employees purchased 865,676, 610,877, and 199,289 shares, respectively, at an average price of $1.02, $2.29 and $11.74, respectively.

As of December 31, 2023, the Company had an immaterial amount of unrecognized stock-based compensation cost related to purchase rights under the employee stock purchase plan.

Stock-based Compensation

In determining the fair value of the stock-based awards, the Company uses the Black-Scholes option-pricing model and assumptions discussed below.

Fair Value of Common Stock— The fair value of the shares of common stock has historically been determined by the Company’s board of directors as there was no public market for the common stock. Subsequent to our IPO, the fair value per share of common stock is the closing price of the Company’s common stock as reported on the applicable grant date.

Expected Term —The expected term represents the period that the Company’s stock options are expected to be outstanding and is determined using the simplified method (based on the mid-point between the vesting date and the end of the contractual term) as the Company has concluded that its stock option exercise history does not provide a reasonable basis upon which to estimate expected term.

Volatility —Because the Company was privately held and did not have an active trading market for its common stock for a sufficient period of time, the expected volatility was estimated based on the average volatility for comparable publicly-traded companies, over a period equal to the expected term of the stock option grants.

Risk-free Rate —The risk-free rate assumption is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of the option.

Dividends —The Company has never paid dividends on its common stock and does not anticipate paying dividends on common stock. Therefore, the Company uses an expected dividend yield of zero.

The following assumptions were used to estimate the fair value of stock options granted in 2019, as there were no stock options granted in 2023, 2022 and 2021:


			Year Ended December 31, 2019
Expected term (in years)			5.0 – 6.1
Expected volatility			44.2% – 47.8%
Average risk-free rate			1.9% – 2.6%
Dividend yield			—

As of December 31, 2023, the Company had approximately $40.3 million of unrecognized stock-based compensation expense related to RSUs and PSUs, which the Company expects to recognize over the remaining weighted-average vesting period of approximately 2.1 years. As of December 31, 2023, the Company had no unrecognized stock-based compensation expense related to options.

Total stock-based compensation expense by function was as follows (in thousands):


	Year Ended December 31,
	2023		2022		2021
Marketing	$	1,550	$	2,209	$	2,557
Operations and technology	12,534		19,822		21,395
Selling, general and administrative	20,189		24,107		24,850
Total	$	34,273	$	46,138	$	48,802

During the year ended December 31, 2022, the Company recognized compensation expense of $1.0 million within selling, general and administrative associated with the modification of certain outstanding equity awards pursuant to the terms of the transition and separation agreement the Company entered into with its founder, Julie Wainwright, in connection with her resignation as Chief Executive Officer on June 6, 2022.

During the years ended December 31, 2023, 2022 and 2021, the Company capitalized $0.8 million, $1.6 million, and $1.4 million of stock-based compensation expense to proprietary software, respectively.

Contingencies

From time to time, the Company is subject to, and it is presently involved in, litigation and other legal proceedings and from time to time, the Company receives inquiries from government agencies. Accounting for contingencies requires the Company to use judgment related to both the likelihood of a loss and the estimate of the amount or range of loss. The Company records a loss contingency when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Company discloses material contingencies when a loss is not probable but reasonably possible.

On November 14, 2018, Chanel, Inc. sued the Company in the U.S. District Court for the Southern District of New York. The Complaint alleged federal and state law claims of trademark infringement, unfair competition, and false advertising. On February 1, 2019, Chanel, Inc. filed its First Amended Complaint that included substantially similar claims against the Company. On March 4, 2019, the Company filed a Motion to Dismiss the First Amended Complaint, which was granted in part and dismissed in part on March 30, 2020. The surviving claims against the Company include trademark infringement under 15 U.S.C. § 1114, false advertising under 15 U.S.C. § 1125, and unfair competition under New York common law. On May 29, 2020, the Company filed its Answer to the Amended Complaint. On November 3, 2020, the Company sought leave to amend its Answer to assert counterclaims against Chanel, Inc. for violations of the Sherman Act, 15 U.S.C. §§ 1 & 2, the Donnelly Act, N.Y. Gen. Bus. Law. § 340, and New York common law. The motion for leave to amend was granted on February 24, 2021. On February 25, 2021, the Company filed its First Amended Answer, Affirmative Defenses and Counterclaims against Chanel. The Company’s Counterclaims allege violations of the Sherman Act, 15 U.S.C. §§ 1 & 2, the Donnelly Act, N.Y. Gen. Bus. Law. § 340, and New York common law. On March 18, 2021, Chanel moved to dismiss the Company’s Counterclaims and moved to strike the Company’s unclean hands affirmative defense. Decisions on Chanel’s motion to dismiss and motion strike are pending. The parties agreed to a stay in April 2021 to engage in settlement discussions. After several mediation sessions, the parties were unable to reach a resolution, and the stay was lifted in November 2021. Chanel then sought a partial stay of discovery on the Company's counterclaims and unclean hands defense while Chanel's motion to dismiss and strike those claims are pending, and on March 10, 2022, the Court granted Chanel's request. The parties have continued to engage in fact discovery regarding Chanel's counterfeiting and false advertising claims against the Company. Fact discovery was scheduled to be completed by August 15, 2023. However, on July 19, 2023, the Court ordered a stay of the case at the parties’ request to enable the parties to attempt mediation again. The parties are working to schedule mediation in the first half of 2024. The final outcome of this litigation, including our liability, if any, with respect to Chanel’s claims, is uncertain. An unfavorable outcome in this or similar litigation could adversely affect the Company’s business and could lead to other similar lawsuits. The Company is not able to predict or reasonably estimate the ultimate outcome or possible losses relating to this claim.

Beginning on September 10, 2019, purported shareholder class action complaints were filed against the Company, its officers and directors and the underwriters of its IPO in the San Mateo Superior Court, Marin County Superior Court, and the United States District Court for the Northern District of California. On July 27, 2021, the Company reached an agreement in principle to settle the shareholder class action. On November 5, 2021, plaintiff filed the executed stipulation of settlement and motion for preliminary approval of the settlement with the federal court. On March 24, 2022, the court entered an order preliminarily approving the settlement. On July 28, 2022, the court entered an order finally approving the settlement and dismissing the case. The financial terms of the stipulation of settlement provide that the Company will pay $11.0 million within thirty (30) days of the later of preliminary approval of the settlement or plaintiff’s counsel providing

payment instructions. The Company paid the settlement amount on March 29, 2022 with available resources and recorded approximately $11.0 million for the year ended December 31, 2021 under our Operating expenses as a Legal settlement. One of the plaintiffs in the Marin County case opted out of the federal settlement and is pursuing the claim in Marin County Superior Court. The stay of the state court case has been lifted, and the opt out plaintiff filed an amended complaint on October 31, 2022 alleging putative class claims under the Securities Act of 1933 (the “Securities Act”) on behalf of the two shareholders who opted out of the settlement and those who purchased stock from November 21, 2019 through March 9, 2020, based on purported new revelations. The claims are for alleged violations of Sections 11 and 15 of the Securities Act. On February 23, 2024, plaintiff filed a motion for class certification, which has been set for hearing on May 28, 2024. While the Company intends to defend vigorously against this litigation, there can be no assurance that the Company will be successful in its defense.

Leases [Abstract]

Leases

The Company leases its corporate offices, retail spaces and authentication centers under various noncancelable operating leases with terms ranging from one year to fifteen years.

The Company recorded operating lease costs of $22.8 million and $29.0 million for the years ended December 31, 2023 and 2022, respectively. The Company incurred $5.2 million and $5.6 million of variable lease costs for the years ended December 31, 2023 and 2022, respectively, which is comprised primarily of the Company’s proportionate share of operating expenses, property taxes and insurance.

Due to the office and store closures in the year ended December 31, 2023, the Company reviewed its right-of-use assets for impairment. Impairment losses are measured and recorded for the excess of carrying value over its fair value, estimated based on expected future cash flows using discount rate and other quantitative and qualitative factors. As a result, the Company recorded $31.1 million related to the impairment of certain office and store right-of-use assets during the year ended December 31, 2023. The impairment charges are included in restructuring in the statements of operations.

During the year ended December 31, 2023, the Company entered into agreements to amend certain of its operating leases. The lease for the Company's corporate headquarters in San Francisco, CA was amended to remove one floor of leased space, and the lease for the Company's offices in New York, NY, was amended to remove two floors of leased space. Additionally, the Company terminated the operating leases for retail locations in Austin, TX, Atlanta, GA, and

Miami, FL. The Company treated the lease termination amendments as lease modifications for accounting purposes as of the applicable effective dates of such terminations which resulted in a decrease of $7.7 million to the related lease liabilities, and a decrease of $1.4 million to the related right-of-use assets for the year ended December 31, 2023. The Company recorded a net gain on the lease terminations of $0.7 million during the year ended December 31, 2023. The net gain on lease terminations is included in restructuring in the statement of operations.

Debt Disclosure [Abstract]

Convertible Senior Notes, Net

In June 2020, the Company issued an aggregate principal of $172.5 million of its 2025 Notes, pursuant to an indenture between the Company and U.S. Bank National Association, as trustee, in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The 2025 Notes include $22.5 million in aggregate principal amount of the 2025 Notes sold to the initial purchasers resulting from the exercise in full of their option to purchase additional Notes. The 2025 Notes will mature on June 15, 2025, unless earlier redeemed or repurchased by the Company or converted.

The Company received net proceeds from the 2025 Notes offering of approximately $165.8 million, after deducting the initial purchasers’ discount and commission and offering expenses. The Company used approximately $22.5 million of the net proceeds from the 2025 Notes offering to fund the net cost of entering into the capped call transactions described below. The Company intends to use the remainder of the net proceeds for general corporate purposes.

In March 2021, the Company issued an aggregate principal of $287.5 million of its 2028 Notes, pursuant to an indenture between the Company and U.S. Bank National Association, as trustee, in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The 2028 Notes include $37.5 million in aggregate principal amount of the 2028 Notes sold to the initial purchasers resulting from the exercise in full of their option to purchase additional Notes. The 2028 Notes will mature on March 1, 2028, unless earlier redeemed or repurchased by the Company or converted.

The Company received net proceeds from the 2028 Notes offering of approximately $278.1 million, after deducting the initial purchasers’ discount and commission and offering expenses. The Company used approximately $33.7 million of the net proceeds from the 2028 Notes offering to fund the net cost of entering into the capped call transactions described below. The Company intends to use the remainder of the net proceeds for general corporate purposes.

The 2025 Notes accrue interest at a rate of 3.00% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on December 15, 2020. The initial conversion rate applicable to the 2025 Notes is 56.2635 shares of common stock per $1,000 principal amount of 2025 Notes (which is equivalent to an initial conversion price of approximately $17.77 per share of the Company’s common stock). The 2028 Notes accrue interest at a rate of 1.00% per annum, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on September 1, 2021. The initial conversion rate applicable to the 2028 Notes is 31.4465 shares of common stock per $1,000 principal amount of 2028 Notes (which is equivalent to an initial conversion price of approximately $31.80 per share of the Company’s common stock). The conversion rate is subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. In addition, upon the occurrence of a corporate event, the Company will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its Notes in connection with such corporate event.

The 2025 Notes will be redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or after June 20, 2023, and the 2028 Notes will be redeemable, in whole or in part, at the Company's option at any time, and from time to time, on or after March 5, 2025, in each case if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately before the date the Company sends the related redemption notice. In addition, calling any Note for redemption will constitute a make-whole fundamental change with respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted after it is called for redemption.

Prior to March 15, 2025, in the case of the 2025 Notes, and December 1, 2027, in the case of the 2028 Notes, the applicable Notes will be convertible only under the following circumstances:

•During any calendar quarter (and only during such calendar quarter), if, the last reported sale price per share of the Company’s common stock exceeds 130% of the applicable conversion price on each applicable trading day for at least 20 trading days (whether or not consecutive) in the period of the 30 consecutive trading day period ending on, and including, the last trading day of the immediately preceding calendar quarter;

•During the five business day period after any five consecutive trading day period in which, for each day of that period, the trading price per $1,000 principal amount of Notes for such trading day was less

than 98% of the product of the last reported sale price of the Company’s common stock and the applicable conversion rate on such trading day;

•Upon the occurrence of specified corporate transactions; or

•If the Company calls any notes for redemption.

On and after March 15, 2025, in the case of the 2025 Notes, and December 1, 2027, in the case of the 2028 Notes, until the close of business on the scheduled trading day immediately preceding the maturity date, holders may convert all or a portion of their Notes, in multiples of $1,000 principal amount, at any time, regardless of the foregoing circumstances. Upon conversion, the Notes will be settled, at the Company’s election, in cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock. It is the Company’s current intent to settle conversions of the 2025 Notes and the 2028 Notes through combination settlement, which involves repayment of the principal portion in cash and any excess of the conversion value over the principal amount in shares of its common stock. The conditions allowing holders of either the 2025 Notes or the 2028 Notes to convert were not met as of December 31, 2023.

The Notes are unsecured and unsubordinated obligations of the Company and will rank senior in right of payment to any of future indebtedness of the Company that is expressly subordinated in right of payment to the Notes; rank equal in right of payment to any existing and future unsecured indebtedness of the Company that is not so subordinated; be effectively subordinated in right of payment to any secured indebtedness of the Company to the extent of the value of the assets securing such indebtedness; and be structurally subordinated to all existing and future indebtedness and other liabilities and obligations incurred by future subsidiaries of the Company.

If bankruptcy, insolvency, or reorganization occurs with respect to the Company (and not solely with respect to a significant subsidiary of the Company), then the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any person. If an event of default (other than bankruptcy, insolvency, or reorganization with respect to the Company and not solely with respect to a significant subsidiary of the Company) occurs and is continuing, then, with the exception of certain reporting events of default, the trustee, by notice to the Company, or noteholders of at least 25% of the aggregate principal amount of 2025 Notes or 2028 Notes, as applicable, then outstanding, by notice to us and the trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the 2025 Notes or 2028 Notes, as applicable, the outstanding to become due and payable immediately.

Prior to the adoption of ASU 2020-06 on January 1, 2022 and in accounting for the issuance of the 2025 Notes and the 2028 Notes, the Company separately accounted for the liability and equity components of the Notes. The debt discount was recorded to equity and was amortized to the debt liability over the life of the Notes using the effective interest method. The equity component was not remeasured as long as it continued to meet the conditions for equity classification.

In connection with the issuance of the 2025 and 2028 Notes, the Company incurred approximately $6.7 million and $9.4 million of debt issuance costs, respectively, which primarily consisted of initial purchasers’ discounts and legal and other professional fees. Prior to the adoption of ASU 2020-06 on January 1, 2022, the Company allocated these costs to the liability and equity components based on the allocation of the proceeds. The portion of these costs allocated to the equity component was recorded as a reduction to additional paid-in capital. The portion of these costs initially allocated to the liability component was recorded as a reduction in the carrying value of the debt on the balance sheets and was amortized to interest expense using the effective interest method over the expected life of the Notes.

On January 1, 2022, the Company adopted ASU 2020-06 based on a modified retrospective transition method. Upon adoption, the Company recorded a cumulative effect of $13.4 million as a reduction to accumulated deficit and a reduction to additional paid in capital of $112.1 million related to amounts attributable to the value of the conversion options that had previously been recorded in equity. Under such transition, prior period information for both the 2025 and 2028 Notes has not been retrospectively adjusted.

In accounting for the 2025 Notes after the adoption of ASU 2020-06, the 2025 Notes are accounted for as a single liability, and the carrying amount of the Notes is $170.6 million as of December 31, 2023, with principal of $172.5 million, net of unamortized issuance costs of $1.9 million. The 2025 Notes were classified as long term liabilities as of December 31, 2023. The issuance costs related to the 2025 Notes are being amortized to interest expense over the expected life of the 2025 Notes or approximately its five-year term at an effective interest rate of 3.74%. In accounting for the 2028 Notes after the adoption of ASU 2020-06, the 2028 Notes are accounted for as a single liability, and the carrying amount of the Notes is $281.9 million as of December 31, 2023, with principal of $287.5 million, net of unamortized issuance costs of

$5.6 million. The 2028 Notes were classified as long term liabilities as of December 31, 2023. The issuance costs related to the 2028 Notes are being amortized to interest expense over the expected life of the 2028 Notes or approximately its seven-year term at an effective interest rate of 1.45%.

Capped Call Transactions with Respect to the 2025 Notes and 2028 Notes

In connection with the issuance of the 2025 Notes and 2028 Notes, including the initial purchasers’ exercise of the option to purchase additional Notes, the Company entered into capped call transactions with respect to its common stock with certain financial institutions (collectively, the “Counterparties”). The Company paid an aggregate amount of approximately $22.5 million to the Counterparties in connection with the 2025 capped call transactions (the “2025 Capped Calls”) and $33.7 million to the Counterparties in connection with the 2028 capped call transactions and (the “2028 Capped Calls” and, together with the 2025 Capped Calls, the “Capped Calls”). The 2025 Capped Calls and 2028 Capped Calls cover approximately 9,705,454 shares and 9,040,869 shares of the Company’s common stock at a strike price that corresponds to the initial conversion price of the 2025 Notes and the 2028 Notes, respectively. The 2025 Capped Calls and the 2028 Capped Calls are subject to anti-dilution adjustments that are intended to be substantially identical to those in the 2025 Notes and the 2028 Notes, as applicable, and are exercisable upon conversion of the 2025 Notes or the 2028 Notes, as applicable. The Capped Calls are subject to adjustment upon the occurrence of specified extraordinary events affecting the Company, including merger events, tender offer and announcement events. In addition, the Capped Calls are subject to certain specified additional disruption events that may give rise to a termination of the Capped Calls, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings and hedging disruptions. The 2025 Capped Calls settle in components commencing on April 16, 2025 with the last component scheduled to expire on June 12, 2025. The 2028 Capped Calls settle in components commencing on December 31, 2027 with the last component scheduled to expire on February 28, 2028.

The cap price of the 2025 Capped Call is initially $27.88 per share, which represents a premium of 100.0% over the closing price of the Company’s common stock of $13.94 per share on June 10, 2020, and is subject to certain adjustments under the terms of the capped call transactions. The cap price of the 2028 Capped Call is initially $48.00 per share, which represents a premium of 100.0% over the closing price of the Company’s common stock of $24.00 per share on March 3, 2021, and is subject to certain adjustments under the terms of the capped call transactions. The Company expects to receive from the Counterparties a number of shares of the Company’s common stock or, at the Company’s election (subject to certain conditions), cash, with an aggregate market value (or, in the case of cash settlement, in an amount) approximately equal to the product of such excess times the number of shares of the Company’s common stock relating to the 2025 Capped Call and 2028 Capped Call being exercised.

These Capped Call instruments meet the conditions outlined in ASC 815-40 to be classified in stockholders’ equity, are not accounted for as derivatives, and are not subsequently remeasured as long as the conditions for equity classification continue to be met. The Company recorded a reduction to additional paid-in capital of approximately $22.5 million and $33.7 million related to the premium payments for the 2025 Capped Call and 2028 Capped Call transactions.

Fair Value Measurement

12 Months Ended

Dec. 31, 2023

Fair Value Disclosures [Abstract]

Fair Value Measurement

Assets and liabilities recorded at fair value on a recurring basis on the balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

Level 1—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

There were no transfers between Level 1, Level 2 or Level 3 of the fair value hierarchy during the periods presented.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

As of December 31, 2023 and December 31, 2022, the Company’s cash equivalents solely consisted of money market funds, which amounted to $124.8 million and $18.1 million, respectively. Money market funds are measured at net asset value per share.

Fair Value Measurements of Other Financial Instruments

The following table presents the carrying amounts and estimated fair values of the financial instruments that are not recorded at fair value on the balance sheets (in millions):


	December 31, 2023
	Net Carrying Amount		Estimated Fair Value
2025 Convertible senior notes	$	170.6	$	128.2
2028 Convertible senior notes	$	281.9	$	100.0

The principal amounts of the 2025 Notes and the 2028 Notes are $172.5 million and $287.5 million, respectively. The difference between the principal amounts of the convertible senior notes and their respective net carrying amounts are the unamortized debt issuance costs.

As of December 31, 2023, the fair value of the 2025 Notes and 2028 Notes, which differs from their carrying value is determined based on the quoted bid prices of the Notes in an over-the counter market using the latest trading information of the reporting period.

- Definition

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