Stockholders' Equity Note [Abstract]

Stockholders’ Deficit

Common stock

The Company’s amended and restated certificate of incorporation authorizes the issuance of Class A common stock, Class B common stock, and Class C common stock. Holders of Class A common stock, Class B common stock, and Class C common stock are entitled to dividends on a pro rata basis, when, as, and if declared by the Company’s Board of Directors, subject to the rights of the holders of the Company’s preferred stock. Holders of Class A common stock are entitled to one vote per share, holders of Class B common stock are entitled to 10 votes per share, and holders of Class C common stock are entitled to zero votes per share.

As of June 30, 2024, the Company had authorized 2,400.0 million shares of Class A common stock, 475.0 million shares of Class B common stock, and 800.0 million shares of Class C common stock, each at par value of $0.00001. Holders of Class B common stock voluntarily converted 0.3 million and 1.0 million shares during the three and six months ended June 30, 2024, respectively, and 0.5 million and 1.0 million shares into an equivalent number of shares of Class A common stock during the three and six months ended June 30, 2023, respectively.

As of June 30, 2024, 238.9 million shares of Class A common stock, 79.8 million shares of Class B common stock, and no shares of Class C common stock were issued and outstanding. As of December 31, 2023, 256.0 million shares of Class A common stock, 80.7 million shares of Class B common stock, and no shares of Class C common stock were issued and outstanding. Class A shares issued and outstanding as of June 30, 2024 and December 31, 2023 exclude unvested restricted stock awards granted to certain executives. Class A shares issued and outstanding also exclude 8.3 million unvested restricted stock awards granted to one of the Company's co-founders as of June 30, 2024 and December 31, 2023, respectively. See "Co-Founder Grant" section below for further details.

Preferred stock

The Company's Board of Directors will have the authority, without further action by the Company's stockholders, to issue up to 240.0 million shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time-to-time by the Board of Directors.

Stock repurchase program

In February 2022, the Board of Directors authorized the Company to repurchase up to $1.2 billion of the Company's outstanding shares of Class A common stock. In July 2023, the Board of Directors further authorized the repurchase of up to an additional $1.2 billion of the outstanding shares of our Class A common stock. The Company completed the February 2022 authorization of $1.2 billion during the three months ended March 31, 2024 and continued stock repurchases under the July 2023 authorization. Share repurchases will be made from time-to-time in private transactions or open market purchases, as permitted by securities laws and other legal requirements and will be subject to a review of the circumstances in place at that time, including prevailing market prices. The program does not obligate the Company to repurchase any specific number of shares and may be discontinued at any time.

During the three and six months ended June 30, 2024, the Company repurchased and subsequently retired 11.3 million and 22.4 million shares of its Class A common stock, respectively, for an aggregate amount of $262.2 million and $543.8 million, respectively. During the three and six months ended June 30, 2023, the Company repurchased and subsequently retired 6.9 million and 15.0 million shares of its Class A common stock, respectively, for an aggregate amount of $155.2 million and $331.7 million, respectively. During the three and six months ended June 30, 2024 and 2023, included in the cost of treasury stock acquired pursuant to common share repurchases, is the 1% excise tax imposed as part of the Inflation Reduction Act.

Equity incentive plans

Under the 2018 Plan, the Company may grant stock-based awards to purchase or directly issue shares of common stock to employees, directors, and consultants. Options are granted at a price per share equal to the fair market value of the Company's common stock at the date of grant. Options granted are exercisable over a maximum term of 10 years from the date of grant and generally vest over a period of four years. RSUs and RSAs are also granted under the 2018 Plan. The 2018 Plan will terminate 10 years after the later of (i) its adoption or (ii) the most recent stockholder-approved increase in the number of shares reserved under the 2018 Plan, unless terminated earlier by the Company's Board of Directors. The 2018 Plan was adopted on March 22, 2018.

In connection with the acquisition of DocSend, the Company assumed unvested stock options and an immaterial number of unvested RSUs that had been granted under DocSend's 2013 Stock Plan and DocSend's 2015 Stock Option and Grant Plan.

As of June 30, 2024, there were 35.7 million stock-based awards issued and outstanding and 117.3 million shares available for issuance under the Dropbox Equity Incentive Plans, Dropbox Sign's 2011 Equity Incentive Plan, DocSend's 2013 Stock Plan and DocSend's 2015 Stock Option and Grant Plan (collectively, the "Plans").

Stock option and restricted stock activity for the Plans was as follows for the six months ended June 30, 2024:


		Options outstanding						Restricted stock outstanding
	Number of shares available for issuance under the Plans	Number of shares outstanding under the Plans	Weighted- average exercise price per share		Weighted- average remaining contractual term (In years)	Aggregate intrinsic value		Number of shares outstanding under the Plans	Weighted- average grant date fair value per share

The following table summarizes information about the pre-tax intrinsic value of options exercised during the three and six months ended June 30, 2024 and 2023:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Intrinsic value of options exercised	$	0.2	$	1.3	$	0.4	$	2.2

As of June 30, 2024, unamortized stock-based compensation related to unvested stock options, restricted stock awards (excluding the Co-Founder Grant), and RSUs was $822.1 million. The weighted-average period over which such compensation expense will be recognized if the requisite service is provided is approximately 2.8 years as of June 30, 2024.

Co-Founder Grant

In December 2017, the Board of Directors approved the Company's Co-Founder Grant, consisting of 10.3 million shares of Class A common stock in the form of RSAs which were granted to Drew Houston, the Company’s co-founder and Chief Executive Officer. This Co-Founder Grant has service-based, market-based, and performance-based vesting conditions. The Co-Founder Grant is excluded from Class A common stock issued and outstanding until the satisfaction of these vesting conditions. The Co-Founder Grant also provides the holder with certain stockholder rights, such as the right to vote the shares with the other holders of Class A common stock and a right to cumulative declared dividends.

The Co-Founder Grant is eligible to vest over the ten-year period following the date the Company’s shares of Class A common stock commenced trading on the Nasdaq Global Select Market in connection with the Company’s IPO. The Co-Founder Grant is comprised of nine tranches that are eligible to vest based on the achievement of stock price goals, each of which are referred to as a Stock Price Target, measured over a consecutive thirty-day trading period during the Performance Period. The Performance Period began on January 1, 2019.

During the first four years of the Performance Period, no more than 20% of the shares subject to the Co-Founder Grant would be eligible to vest in any calendar year. After the first four years, all shares are eligible to vest based on the achievement of the Stock Price Targets.

The first tranche of the Co-Founder Grant, or 2.1 million shares of Class A common stock, vested in the fourth quarter of 2021. The stock-based compensation expense for Mr. Houston's Co-Founder Grant is recognized utilizing the accelerated attribution method over the requisite service period identified as the derived service period over which the market conditions are expected to be achieved, and is not reversed if the market conditions are not satisfied. Therefore no incremental stock-based compensation was recognized upon vesting of these RSAs.

The Company recognized stock-based compensation expense related to the Co-Founder Grant of $0.7 million and $1.8 million during the three and six months ended June 30, 2024, respectively, and $2.0 and $4.2 during the three and six months ended June 30, 2023, respectively. As of June 30, 2024, unamortized stock-based compensation expense related to the Co-Founder Grant was $0.6 million.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of the Business and Summary of Significant Accounting Policies

Business

Dropbox, Inc. (the “Company” or “Dropbox”) helps keep life organized and work moving. The Company was incorporated in May 2007 as Evenflow, Inc., a Delaware corporation, and changed its name to Dropbox, Inc. in October 2009. The Company is headquartered in San Francisco, California.

Basis of presentation and consolidation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the United States of America generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the SEC regarding interim financial reporting. The accompanying unaudited condensed consolidated financial statements include the accounts of Dropbox and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

The condensed consolidated balance sheet as of December 31, 2023 included herein was derived from the audited financial statements as of that date. The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the balance sheets, statements of operations, statements of comprehensive income, statements of stockholders' deficit and the statements of cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ended December 31, 2024 or any future period.

The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2023, included in the Company's Annual Report on Form 10-K on file with the SEC ("Annual Report").

Use of estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the Company’s condensed consolidated financial statements and accompanying notes. These estimates are based on information available as of the date of the condensed consolidated financial statements. Management evaluates these estimates and assumptions on a regular basis. Actual results may differ materially from these estimates.

The Company’s most significant estimates and judgments are related to the valuation of right-of-use and other lease related property and equipment assets as well as income taxes.

The Company reviews the useful lives of long-lived assets on an ongoing basis, and effective January 1, 2024, the Company changed the estimate of the useful lives of certain infrastructure server and component assets, which are included in property and equipment, net and are depreciated through cost of revenue, from four to five years. The Company has extended the economic life of these assets in light of recent technological advancements. The effect of this change in estimate during the three months ended June 30, 2024 was a reduction in depreciation expense of $9.0 million, and a benefit to net income of $7.1 million or $0.02 per basic and diluted share. The effect of this change in estimate during the six months ended June 30, 2024 was a reduction in depreciation expense of $19.4 million, and a benefit to net income of $15.2 million or $0.05 per basic and diluted share. The Company estimates that this change in estimate will have a favorable impact to cost of revenue in fiscal year 2024 of approximately $30.5 million. The impact from the change in the Company's estimate was calculated based on assets that existed as of the effective date of the change and applying the revised estimated useful lives prospectively.

Financial information about segments and geographic areas

The Company manages its operations and allocates resources as a single operating segment. Further, the Company manages, monitors, and reports its financials as a single reporting segment. The Company’s chief operating decision-maker is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance, and allocating resources. See Note 14 "Geographic Areas" to the Company's condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for information regarding the Company’s long-lived assets and revenue by geography.

Foreign currency transactions

The assets and liabilities of the Company’s foreign subsidiaries are translated from their respective functional currencies into U.S. dollars at the exchange rates in effect at the balance sheet date. Revenue and expense amounts are translated at the average exchange rate for the period. Foreign currency translation gains and losses are recorded in other comprehensive income, net of tax.

Gains and losses realized from foreign currency transactions (those transactions denominated in currencies other than the foreign subsidiaries’ functional currency) are included in other income (loss), net. Monetary assets and liabilities are remeasured using foreign currency exchange rates at the end of the period, and non-monetary assets are remeasured based on historical exchange rates. Foreign currency transaction gains or losses were immaterial during the three and six months ended June 30, 2024 and 2023, respectively.

Revenue recognition

The Company derives its revenue from subscription fees from customers for access to its platform. The Company’s policy is to exclude sales and other indirect taxes when measuring the transaction price of its subscription agreements. The Company accounts for revenue contracts with customers through the following steps:

•Identification of the contract, or contracts, with a customer

•Identification of the performance obligations in the contract

•Determination of the transaction price

•Allocation of the transaction price to the performance obligations in the contract

•Recognition of revenue when, or as, the Company satisfies a performance obligation

The Company’s subscription agreements are generally non-cancelable and have monthly or annual contractual terms with a small percentage having multi-year contractual terms. Revenue is recognized ratably over the related contractual term beginning on the date that the platform is made available to a customer. Access to the platform represents a series of distinct services as the Company continually provides access to, and fulfills its obligation to the end customer over the subscription term. The series of distinct services represents a single performance obligation that is satisfied over time. The Company recognizes revenue ratably because the customer receives and consumes the benefits of the platform throughout the contract period.

The Company bills in advance for monthly contracts and typically bills annually in advance for contracts with terms of one year or longer. The Company also recognizes an immaterial amount of contract assets, or unbilled receivables, primarily related to consideration for services completed but not billed at the reporting date. Unbilled receivables are classified as receivables when the Company has the right to invoice the customer.

The Company records contract liabilities when cash payments are received or due in advance of performance to deferred revenue. Deferred revenue primarily relates to the advance consideration received from the customer.

The price of subscriptions is generally fixed at contract inception and therefore, the Company’s contracts do not contain a significant amount of variable consideration. As a result, the amount of revenue recognized in the periods presented from performance obligations satisfied (or partially satisfied) in previous periods was not material.

The Company recognized $348.4 million and $555.5 million of revenue during the three and six months ended June 30, 2024, respectively, and recognized $341.9 million and $536.7 million of revenue during the three and six months ended June 30, 2023, respectively, that was included in the deferred revenue balances at the beginning of their respective periods.

As of June 30, 2024, future estimated revenue related to performance obligations that were unsatisfied or partially unsatisfied was $818.3 million. The substantial majority of the unsatisfied performance obligations will be satisfied over the next twelve months.

Stock-based compensation

The Company has primarily granted restricted stock units (“RSUs”) to its employees and members of the Board of Directors under the 2008 Equity Incentive Plan (“2008 Plan”), the 2017 Equity Incentive Plan (“2017 Plan”), and the 2018 Equity Incentive Plan (“2018 Plan” and together with the 2008 Plan and 2017 Plan, the "Dropbox Equity Incentive Plans”). Since August 2015, the Company has granted RSUs, which have a service based vesting condition over a four-year period vesting quarterly, as the only stock-based awards to its employees, with the exception of restricted stock awards ("RSAs") granted to its co-founder and certain executives, and has not granted any stock options to employees under the Dropbox Equity Incentive Plans. The Company recognizes compensation expense associated with RSUs on a straight-line basis over the requisite service period and accounts for forfeitures in the period in which they occur.

The Board of Directors determines the fair value of each share of underlying common stock based on the closing price of the Company's Class A common stock as reported on the Nasdaq Global Select Market on the date of the grant.

In December 2017, the Board of Directors approved the Company’s Co-Founder Grant, consisting of 10.3 million shares of Class A Common Stock in the form of RSAs which were granted to Drew Houston, the Company’s co-founder and Chief Executive Officer. This Co-Founder Grant has service-based, market-based, and performance-based vesting conditions. The Co-Founder Grant is excluded from Class A common stock issued and outstanding until the satisfaction of these vesting conditions. The Company estimated the grant date fair value of the Co-Founder Grant using a model based on multiple stock price paths developed through the use of a Monte Carlo simulation that incorporates into the valuation the possibility that certain stock price targets may not be satisfied. The first tranche of the Co-Founder Grant vested in the fourth quarter of 2021. The stock-based compensation expense for the Co-Founder Grant is recognized utilizing the accelerated attribution method over the requisite service period identified as the derived service period over which the market conditions are expected to be achieved, and is not reversed if the market conditions are not satisfied. Therefore no incremental stock-based compensation was recognized upon vesting of these RSAs. See Note 11, "Stockholders' Deficit" to the Company's condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for further information.

Cost of revenue

Cost of revenue consists primarily of expenses associated with the storage, delivery, and distribution of the Company’s platform for both paying users and free users. These costs, which are referred to as infrastructure costs, include depreciation of servers located in co-location facilities that the Company leases and operates, rent and facilities expense for those datacenters, network and bandwidth costs, support and maintenance costs for infrastructure equipment, and payments to third-party datacenter service providers. Cost of revenue also includes salaries, bonuses, benefits, travel-related expenses, and stock-based compensation, which are referred to as employee-related costs, for employees whose primary responsibilities relate to supporting the Company’s infrastructure and delivering user support. Other non-employee costs included in cost of revenue include credit card fees related to processing customer transactions and allocated overhead, such as facilities, including rent, utilities, depreciation on leasehold improvements and other equipment shared by all departments, and shared information technology costs. In addition, cost of revenue includes amortization of developed technologies, professional fees related to user support initiatives, and property taxes related to the datacenters.

Reduction in Workforce

On April 27, 2023, the Company announced a reduction of its global workforce by approximately 16% to streamline its team structure in support of its long-term growth and profitability objectives. During the three and six months ended June 30, 2023, the Company incurred $37.5 million in charges in connection with the reduction in workforce, primarily consisting of cash expenditures for severance payments, employee benefits and related costs.

These severance charges are included within the Company's condensed consolidated statements of operations for the three and six months ended June 30, 2023 as follows:


	Severance and Related Costs
Cost of revenue	$	2.7
Research and development	27.0
Sales and marketing	6.3
General and administrative	1.5
Total Charges	$	37.5

Cash and cash equivalents

Cash consists primarily of cash on deposit with banks and includes amounts in transit from payment processors for credit and debit card transactions, which typically settle within five business days. Cash equivalents include highly liquid investments purchased with an original maturity date of 90 days or less from the date of purchase.

The Company monitors its credit risk by considering factors such as historical experience, credit ratings, current economic conditions, and reasonable and supportable forecasts.

Short-term investments

The Company’s short-term investments are primarily comprised of corporate notes and obligations, U.S. Treasury securities, certificates of deposit, asset-backed securities, commercial paper, U.S. agency obligations, foreign government securities, supranational securities, and municipal securities. The Company determines the appropriate classification of its short-term investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its short-term investments as available-for-sale securities as the Company may sell these securities at any time for use in its current operations or for other purposes, even prior to maturity. As a result, the Company classifies its short-term investments, including securities with stated maturities beyond twelve months, within current assets in the condensed consolidated balance sheets.

The Company's short-term investments are recorded at fair value each reporting period. Unrealized gains and losses on these short-term investments are reported as a separate component of accumulated other comprehensive loss in the condensed consolidated balance sheets until realized. Unrealized gains and losses for any short-term investments that management intends to sell or it is more likely than not that management will be required to sell prior to their anticipated recovery are recorded in other income (loss), net. The Company segments its portfolio based on the underlying risk profiles of the securities and has a zero-loss expectation for U.S. treasury and U.S. government agency securities. The Company regularly reviews the securities in an unrealized loss position and evaluates the current expected credit loss by considering factors such as credit ratings, issuer-specific factors, current economic conditions, and reasonable and supportable forecasts. The Company did not record any material credit losses during the three and six months ended June 30, 2024. As of June 30, 2024 and December 31, 2023, no allowance for credit losses in short-term investments was recorded.

Concentrations of credit risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, accounts receivable, and short-term investments. Although the Company deposits its cash and cash equivalents with multiple well-established financial institutions, the deposits, at times, may exceed federally insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents and management believes that the institutions where the Company has deposits are financially stable and, accordingly, minimal credit risk exists.

Trade accounts receivable are typically unsecured and are derived from revenue earned from customers located around the world. Two distribution partners accounted for 11% and 47% of total trade and other receivables, net as of June 30, 2024. Two distribution partners accounted for 11% and 43% of total trade and other receivables, net as of December 31, 2023. No customer accounted for more than 10% of the Company’s revenue in the periods presented.

Deferred commissions, net

Deferred commissions, net is stated as gross deferred commissions less accumulated amortization. Deferred commissions are considered to be incremental and recoverable costs of obtaining a contract with a customer such as sales commissions earned by the Company’s sales force including related payroll taxes and revenue share earned by strategic partners. These amounts have been capitalized as deferred commissions within prepaid and other current assets and other assets on the condensed consolidated balance sheets. The Company deferred incremental costs of obtaining a contract of $7.9 million and $15.5 million during the three and six months ended June 30, 2024, respectively and $6.2 million and $12.3 million during the three and six months ended June 30, 2023, respectively.

Deferred commissions, net included in prepaid and other current assets were $23.7 million and $23.4 million as of June 30, 2024 and December 31, 2023, respectively. Deferred commissions, net included in other assets were $22.3 million and $22.0 million as of June 30, 2024 and December 31, 2023, respectively.

Commissions related to new contracts are typically deferred and amortized over a period of benefit of five years. The period of benefit was estimated by considering factors such as historical customer attrition rates, the useful life of the Company’s technology, and the impact of competition in its industry. Commissions that are commensurate with renewal contracts are typically amortized over one year. Amortization of deferred commissions was $7.4 million and $14.9 million for the three and six months ended June 30, 2024, respectively and $10.1 million and $20.8 million for the three and six months ended June 30, 2023, respectively. Amortization of deferred commissions costs are included in sales and marketing expense in the accompanying condensed consolidated statements of operations. There was no impairment loss in relation to the deferred costs for any period presented.

Property and equipment, net

Equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful life of the related asset, which is generally three to seven years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the term of the related lease.

The following table presents the estimated useful lives of property and equipment:


Property and equipment						Useful life
Datacenter and other computer equipment						3 to 5 years
Office equipment and other						3 to 7 years
Leasehold improvements						Lesser of estimated useful life or remaining lease term

Lease obligations

The Company leases office space, datacenters, and equipment under non-cancelable finance and operating leases with various expiration dates through 2036. The Company determines if an arrangement contains a lease at inception.

Operating lease right-of-use assets and lease liabilities are recognized at the present value of the future lease payments at commencement date. The interest rate implicit in the Company’s operating leases is not readily determinable, and therefore an incremental borrowing rate is estimated to determine the present value of future payments. The estimated incremental borrowing rate factors in a hypothetical interest rate on a collateralized basis with similar terms, payments, and economic environments. Operating lease right-of-use assets also include any prepaid lease payments and lease incentives.

Certain of the operating lease agreements contain rent concession, rent escalation, and option to renew provisions. Rent concession and rent escalation provisions are considered in determining the single lease cost to be recorded over the lease term. Single lease cost is recognized on a straight-line basis over the lease term commencing on the date the Company has the right to use the leased property. The lease terms may include options to extend or terminate the lease. The Company generally uses the base, non-cancelable, lease term when recognizing the lease assets and liabilities, unless it is reasonably certain that the option will be exercised.

In addition, certain operating lease agreements contain tenant improvement allowances from its landlords. These allowances are accounted for as lease incentives and decrease the Company's right-of-use asset and reduce single lease cost over the lease term.

As part of the Company's Virtual First strategy, Dropbox has retained a portion of its office space for in-person collaboration while the remainder will be subleased. The Company did not recognize any impairment charges during the three and six months ended June 30, 2024, respectively, compared to $2.2 million of impairment charges during the three and six months ended June 30, 2023, respectively, related to right-of-use assets and other lease related property and equipment assets. See Note 8 "Leases" to our condensed consolidated financial statements included elsewhere in the Quarterly Report on Form 10-Q for further information.

The Company leases certain equipment from various third parties, through equipment finance leases. These leases either include a bargain purchase option, a full transfer of ownership at the completion of the lease term, or the terms of the leases are at least 75 percent of the useful lives of the assets and are therefore classified as finance leases. These leases are capitalized in property and equipment, net and the related amortization of assets under finance leases is included in depreciation and amortization expense. Initial asset values and finance lease obligations are based on the present value of future minimum lease payments.

The Company’s finance lease agreements may contain lease and non-lease components. The non-lease components include payments for support on infrastructure equipment obtained via finance leases, which when not significant in relation to the overall agreement, are combined with the lease components and accounted for together as a single lease component.

Business combinations

The Company uses best estimates and assumptions, including but not limited to, future expected cash flows, expected asset lives, and discount rates, to assign a fair value to the tangible and intangible assets acquired and liabilities assumed in business combinations as of the acquisition date. These estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed may be recorded, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s condensed consolidated statements of operations.

Long-lived assets, including goodwill and other acquired intangible assets, net

The Company evaluates the recoverability of its property and equipment and finite-lived intangible assets for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. The evaluation is performed at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review determines that the carrying amount of specific property and equipment or intangible assets is not recoverable, the carrying amount of such assets is reduced to its fair value.

The Company reviews goodwill for impairment at least annually in the fourth quarter, or more frequently if events or changes in circumstances would more likely than not reduce the fair value of its single reporting unit below its carrying value.

The Company has not recorded impairment charges on goodwill or intangible assets for the periods presented in these condensed consolidated financial statements.

The Company did not recognize any impairment charges during the three and six months ended June 30, 2024, respectively. The Company recognized impairment charges of $2.2 million during the three and six months ended June 30, 2023, respectively, related to right-of-use assets and other lease related property and equipment assets.

Acquired property and equipment and finite-lived intangible assets are amortized over their useful lives. The Company evaluates the estimated remaining useful life of these assets when events or changes in circumstances warrant a revision to the remaining period of depreciation or amortization. If the Company revises the estimated useful life assumption for any asset, the remaining unamortized balance is amortized or depreciated over the revised estimated useful life on a prospective basis. In the

first quarter of 2024, the Company changed the estimate of the useful lives of certain infrastructure server and component assets from four to five years. See "Use of estimates" within Note 1 above for further information.

Income taxes

Deferred income tax balances reflect the effects of temporary differences between the financial reporting and tax bases of the Company’s assets and liabilities using enacted tax rates expected to apply when taxes are actually paid or recovered. In addition, deferred tax assets are recorded for net operating loss and credit carryforwards.

A valuation allowance is provided against deferred tax assets unless it is more likely than not that they will be realized based on all available positive and negative evidence. Such evidence includes, but is not limited to, recent cumulative earnings or losses, expectations of future taxable income by taxing jurisdiction, and the carry-forward periods available for the utilization of deferred tax assets.

The Company uses a two-step approach to recognizing and measuring uncertain income tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit. The second step is to measure the tax benefit as the largest amount, which is more than 50% likely of being realized upon ultimate settlement. The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense.

Although the Company believes that it has adequately reserved for its uncertain tax positions, it can provide no assurance that the final tax outcome of these matters will not be materially different. The Company evaluates its uncertain tax positions on a regular basis and evaluations are based on a number of factors, including changes in facts and circumstances, changes in tax law, correspondence with tax authorities during the course of an audit, and effective settlement of audit issues.

To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made and could have a material impact on the Company’s financial condition and results of operations.

The Tax Cuts and Jobs Act of 2017 ("TCJA") subjects a U.S. shareholder to current tax on global intangible low-taxed income ("GILTI") earned by foreign subsidiaries. The Company accounts for GILTI as a period cost as incurred.

Fair value measurement

The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value measurements for assets and liabilities, the Company considers the principal or most advantageous market in which it would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as risks inherent in valuation techniques, transfer restrictions, and credit risk. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

Recently issued accounting pronouncements not yet adopted

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosure of incremental segment information on an annual and interim basis. The amendments are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. This change requires application on a fully retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of this standard on the Company's consolidated financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance income tax disclosures primarily through changes in rate reconciliation and income taxes paid disclosures. The amendments in ASU 2023-09 are effective for annual periods beginning after December 15, 2024 on a prospective basis. Early adoption is permitted. The Company is currently evaluating the impact of this standard on the Company's consolidated financial statement disclosures.

Goodwill

Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired.Goodwill amounts are not amortized, but tested for impairment on an annual basis.

Net income per share

The Company computes net income per share using the two-class method required for multiple classes of common stock and participating securities. The rights, including the liquidation and dividend rights, of the Class A common stock and Class B common stock are substantially identical, other than voting rights. Accordingly, the Class A common stock and Class B common stock share equally in the Company’s net income and losses.

Fair Value Disclosures [Abstract]

Fair Value Measurements

The Company measures its financial instruments at fair value each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

The following table presents information about the Company’s financial instruments that are measured at fair value on a recurring basis using the input categories discussed in Note 1:

The Company had no transfers between levels of the fair value hierarchy during the periods presented.

The carrying amounts of certain financial instruments, including cash held in banks, accounts receivable and accounts payable approximate fair value due to their short-term maturities and are excluded from the fair value table above.

The Company had $695.8 million in aggregate principal amount of 0% convertible senior notes due in 2026 (the "2026 Notes"), and $693.3 million in aggregate principal amount of 0% convertible senior notes due in 2028 (the "2028 Notes" and together with the 2026 Notes, the "Notes"), outstanding as of June 30, 2024. Refer to Note 7 "Debt" for further details on the 2026 Notes and 2028 Notes.

The estimated fair value of the 2026 Notes and the 2028 Notes, based on a market approach as of June 30, 2024 was approximately $648.3 million and $627.4 million, respectively. The Notes were categorized as Level 2 instruments as the estimated fair value was determined based on the estimated or actual bids and offers of the Notes in an over-the-counter market on the last business day of the period.

Trading Arrangements, by Individual
Material Terms of Trading Arrangement		On May 15, 2024, Tim Regan, our Chief Financial Officer, adopted a Rule 10b5-1 trading arrangement providing for the sale from time-to-time of an aggregate of up to 125,000 shares of our Class A common stock, although we expect the total number of such shares sold will ultimately be less than this amount due to withholding for applicable taxes. The trading arrangement is intended to satisfy the affirmative defense in Rule 10b5-1(c). The duration of the trading arrangement is until September 2, 2025, or earlier if all transactions under the trading arrangement are completed.

Net Income Per Share

6 Months Ended

Jun. 30, 2024

Earnings Per Share [Abstract]

Net Income Per Share

Basic net income per share is computed by dividing net income attributable to common stockholders by the weighted-average number of shares of the Class A and Class B common stock outstanding.

Diluted net income per share is computed by dividing net income attributable to common stockholders by the weighted-average number of diluted common shares outstanding. The computation of the diluted net income per share of Class A common stock assumes the conversion of the Company's Class B common stock to Class A common stock, while the diluted net income per share of Class B common stock does not assume the conversion of those shares to Class A common stock. The dilutive effect of potentially dilutive common shares is reflected in diluted earnings per share by application of the if-converted method for the 2026 Notes and the 2028 Notes, and by application of the treasury stock method for the Company's other potentially dilutive securities.

The numerators and denominators of the basic and diluted EPS computations for the Company's common stock are calculated as follows (in millions, except for per share amounts):

Unrealized losses on short-term investments have not been recorded into income because management does not intend to sell nor will be required to sell these securities prior to their anticipated recovery, and for which the decline in fair value is largely due to changes in interest rates. The credit ratings associated with the corporate notes and obligations are mostly unchanged, are highly rated and the issuers continue to make timely principal and interest payments.

The Company recorded interest income from its cash, cash equivalents, and short-term investments of $9.5 million and $21.5 million during the three and six months ended June 30, 2024, respectively and $7.4 million and $14.6 million during the three and six months ended June 30, 2023, respectively.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2024
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company computed the year-to-date income tax provision by applying the estimated annual effective tax rate to the year-to-date pre-tax income and adjusting for discrete tax items in the period. The Company's provision for income taxes was $23.1 million and $41.9 million for the three and six months ended June 30, 2024, respectively, and $15.8 million and $34.4 million for the three and six months ended June 30, 2023, respectively. For the three and six months ended June 30, 2024, and June 30, 2023, the difference between the U.S. statutory rate and the Company's effective tax rate was primarily due to jurisdictional mix of earnings, tax credits, and state income taxes. The Company periodically evaluates the realizability of its net deferred tax assets based on all available evidence, both positive and negative. The realization of net deferred tax assets is dependent on the Company's ability to generate sufficient future taxable income during periods prior to the expiration of tax attributes to fully utilize these assets. As of June 30, 2024, the Company continues to maintain valuation allowances against its deferred tax assets in certain states and one foreign jurisdiction. The Company is subject to income tax audits in the U.S. and foreign jurisdictions. The Company records liabilities related to uncertain tax positions and believes that it has provided adequate reserves for income tax uncertainties in all open tax years. Unrecognized tax benefits increased by $11.6 million during the six months ended June 30, 2024. The increase was primarily driven by a gross increase in unrecognized tax benefits related to tax positions taken in the period of approximately $11.4 million, of which $8.7 million, if recognized, would affect the Company's effective tax rate and $2.7 million would result in adjustment to deferred tax assets with corresponding adjustments to the valuation allowance. It is reasonably possible that there could be changes to the amount of uncertain tax positions due to activities of the taxing authorities, settlement of audit issues, reassessment of existing uncertain tax positions, or the expiration of applicable statutes of limitations; however, the Company is not able to estimate the impact of these items at this time. The Organization for Economic Cooperation and Development (“OECD”) and many countries have proposed to reallocate some portion of profits of large multinational companies with global revenues exceeding EUR20 billion to markets where sales arise (“Pillar One”), as well as enact a global minimum tax rate of at least 15% for multinationals with global revenue exceeding EUR750 million (“Pillar Two”), and many countries are considering or have begun to adopt these proposals. In December 2022, the Council of the European Union (“EU”) formally adopted the EU Minimum Tax Directive, which would require member states to adopt Pillar Two into their domestic law effective for fiscal years starting on or after December 31, 2023. Ireland and certain jurisdictions in which the Company operates have enacted legislation to implement Pillar Two. Other countries are actively considering changes to their tax laws to adopt certain parts of the OECD’s proposals.

The Company will continue to monitor and reflect the impact of such legislative changes in future financial statements as appropriate.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal matters From time-to-time, the Company is a party to a variety of claims, lawsuits, investigations, inquiries, and proceedings which arise in the ordinary course of business, including claims of alleged infringement of intellectual property rights, regulatory matters, and commercial disputes. The Company records a liability when it believes that it is probable that a loss will be incurred and the amount of loss or range of loss can be reasonably estimated. In its opinion, resolution of pending matters is not likely to have a material adverse impact on its consolidated results of operations, cash flows, or its financial position. Given the unpredictable nature of legal proceedings, the Company bases its estimate on the information available at the time of the assessment. As additional information becomes available, the Company reassesses the potential liability and may revise the estimate. Indemnification The Company’s arrangements generally include certain provisions for indemnifying customers against liabilities if its products or services infringe a third party’s intellectual property rights. It is not possible to determine the maximum potential amount under these indemnification obligations due to the limited history of prior indemnification claims. Other commitments Other commitments include payments to third-party vendors for services related to the Company’s infrastructure, infrastructure warranty contracts, and asset retirement obligations for office modifications. There have been no material changes in the Company's other commitments, as disclosed in the Annual Report.

Debt Disclosure [Abstract]

Debt

Revolving credit facility

In February 2018, the Company entered into an amendment to the revolving credit facility to, among other things, permit the Company to make certain investments, enter into an unsecured standby letter of credit facility and increase its standby letter of credit sublimit to $187.5 million. The Company increased its borrowing capacity under the revolving credit facility from $600.0 million to $725.0 million. In February 2021, the Company amended the revolving credit facility to decrease its borrowing capacity under the revolving credit facility from $725.0 million to $500.0 million, the letter of credit sublimit from $187.5 million to $65.0 million and extended the term of the agreement through February 2026. The Company may from time-to-time request increases in its borrowing capacity under the revolving credit facility of up to $250.0 million, provided no event of default has occurred or is continuing or would result from such increase. In conjunction with the February 2021 amendment, the Company paid upfront issuance fees of $1.7 million, which are being amortized over the remaining term of the agreement, and wrote-off $0.2 million in unamortized deferred debt issuance costs. In March 2023, the Company amended the revolving credit facility to update its borrowing benchmark from LIBOR to SOFR, with a fixed credit spread adjustment of 0.10%. In conjunction with the March 2023 amendment, the Company incurred upfront issuance fees of $0.1 million, which are being amortized over the remaining term of the agreement.

Pursuant to the terms of the revolving credit facility, the Company may issue letters of credit under the revolving credit facility, which reduce the total amount available for borrowing. Pursuant to the terms of the revolving credit facility, the Company is required to pay an annual commitment fee that accrues at a rate of 0.20% per annum on the unused portion of the borrowing commitments under the revolving credit facility. In addition, the Company is required to pay a fee in connection with letters of credit issued under the revolving credit facility, which accrues at a rate of 1.375% per annum on the amount of such letters of credit outstanding. There is an additional fronting fee of 0.125% per annum multiplied by the average aggregate

daily maximum amount available under all letters of credit. Borrowings under the revolving credit facility bear interest, at the Company’s option, at an annual rate based on credit spread adjusted SOFR plus a spread of 1.375% or at an alternative base rate plus a spread of 0.375%.

The revolving credit facility contains customary conditions to borrowing, events of default and covenants, including covenants that restrict the Company’s ability to incur indebtedness, grant liens, make distributions to holders of the Company or its subsidiaries’ equity interests, make investments, or engage in transactions with its affiliates. In addition, the revolving credit facility contains financial covenants, including a consolidated leverage ratio incurrence covenant and a minimum liquidity balance of $100.0 million, which includes any available borrowing capacity. The Company was in compliance with the covenants of the revolving credit facility as of June 30, 2024 and December 31, 2023, respectively.

The Company had an aggregate of $30.4 million of letters of credit outstanding under the revolving credit facility as of June 30, 2024, and the Company’s total available borrowing capacity under the revolving credit facility was $469.6 million as of June 30, 2024. The Company’s letters of credit have final expiration dates through 2036.

Convertible senior notes

During the first quarter of 2021, the Company issued $695.8 million aggregate principal amount of the 2026 Notes. Additionally, during the first quarter of 2021, the Company issued $693.3 million aggregate principal amount of the 2028 Notes. The Notes were issued in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. The net proceeds from the sale of the Notes were approximately $1.4 billion after deducting offering and issuance costs related to the Notes.

The Notes of each series do not bear regular interest. The Notes of each series may bear special interest as the remedy relating to the Company’s failure to comply with certain of its reporting obligations. The Company has complied with these reporting obligations from the issuance date through June 30, 2024. The 2026 Notes will mature on March 1, 2026, and the 2028 Notes will mature on March 1, 2028, in each case, unless earlier converted, redeemed or repurchased.

The initial conversion rate for the 2026 Notes is 26.1458 shares of the Company’s Class A common stock per $1,000 principal amount of such Note, which is equivalent to an initial conversion price of approximately $38.25 per share. The initial conversion rate for the 2028 Notes is 28.2889 shares of Class A common stock per $1,000 principal amount of such Notes, which is equivalent to an initial conversion price of approximately $35.35 per share. The conversion rate for each series of Notes will be subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid special interest. In addition, upon the occurrence of a make-whole fundamental change (as defined in the relevant indentures governing the Notes) or a notice of redemption, the Company will, in certain circumstances, increase the conversion rate of the relevant series of Notes by a number of additional shares for a holder that elects to convert all or a portion of its Notes of such series in connection with such make-whole fundamental change or who elects to convert such Notes that are subject to such notice of redemption. The conversion rate for the 2026 Notes and the 2028 Notes shall not exceed 43.1406 shares per $1,000 principal amount of such Notes, subject to certain customary anti-dilution adjustments (as defined in the relevant indentures governing the Notes). There have been no changes to the initial conversion price of the Notes since issuance as of June 30, 2024.

Upon conversion, the principal portion of the Notes of the applicable series being converted will be settled in cash, and any amount in excess of the principal portion of such Notes will be settled in cash or shares of the Company’s Class A common stock or any combination thereof at the Company’s option. The if-converted value of the 2026 Notes and the 2028 Notes was below the principal value of the respective Notes as of June 30, 2024. In addition, during the three and six months ended June 30, 2024 the conditions allowing holders of the Notes to convert during the following fiscal quarter were not met.

Prior to the close of business on the business day immediately preceding December 1, 2025, in the case of the 2026 Notes, and prior to the close of business on the business day immediately preceding December 1, 2027, in the case of the 2028 Notes, the Notes of the applicable series will be convertible only under the following circumstances: (1) during any calendar quarter commencing after June 30, 2021 (and only during such calendar quarter), if the last reported sale price of the Class A common stock for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading day period ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the relevant series of Notes on each applicable trading day; (2) during the five business day period after any five consecutive trading day period in which, for each trading day of that period, the trading price per $1,000 principal amount of 2026 Notes or

2028 Notes, as applicable, for such trading day was less than 98% of the product of the last reported sale price of the Class A common stock and the conversion rate for such series of Notes on each such trading day; (3) if the Company calls any or all of the Notes for redemption, such Notes of the applicable series called for redemption may be converted at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate transactions.

On or after December 1, 2025, in the case of the 2026 Notes, and on or after December 1, 2027, in the case of the 2028 Notes, until the close of business on the second scheduled trading day immediately preceding the relevant maturity date, holders of the relevant series of Notes may convert all or a portion of their Notes of such series regardless of the foregoing conditions.

The Company may redeem for cash all or any part of the Notes, at its option, on or after March 6, 2024, in the case of the 2026 Notes, and on or after March 6, 2025, in the case of the 2028 Notes, if the last reported sale price of its Class A common stock has been at least 130% of the conversion price for the relevant series of Notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the series of Notes to be redeemed, plus any accrued and unpaid special interest to, but excluding, the redemption date. No sinking fund is provided for the Notes.

Upon the occurrence of a fundamental change (as defined in the relevant indentures governing the Notes) prior to the relevant maturity date, holders of the relevant series of Notes may require the Company to repurchase all or a portion of the Notes of such series for cash at a price equal to 100% of the principal amount of the series of Notes to be repurchased, plus any accrued and unpaid special interest to, but excluding, the fundamental change repurchase date. Additionally, and upon events of default (as defined in the relevant indentures governing the Notes), the maturity of the Notes may be accelerated.

The Notes are the Company’s general unsecured obligations and will rank senior in right of payment to any existing and future indebtedness that is contractually subordinated to the Notes; rank equal in right of payment with the Company’s existing and future senior unsecured indebtedness that is not so subordinated; effectively rank junior in right of payment to any of the Company’s existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness; and be structurally subordinated to all indebtedness and other liabilities (including trade payables) of subsidiaries of the Company.

In accounting for the Notes, issuance costs of $11.0 million and $11.0 million for the 2026 Notes and the 2028 Notes, respectively, were deducted from the carrying value of the Notes in the consolidated balance sheet. Issuance costs will be recognized as interest expense over the five-year term and seven-year term for the 2026 Notes and the 2028 Notes, respectively.

The following is a summary of the Notes as of June 30, 2024 and December 31, 2023.

During the six months ended June 30, 2024 and 2023, the Company recognized $1.1 million and $1.1 million in interest expense for the 2026 Notes and $0.8 million and $0.8 million in interest expense for the 2028 Notes, respectively, with such interest expense solely consisting of amortization of issuance costs.

Convertible Note Hedges and Warrants

Concurrent with the offering of the Notes, the Company entered into convertible note hedge transactions with certain counterparties whereby the Company had the option to purchase a total of approximately 18.2 million shares for note hedges expiring in March 2026 (the “2026 Note Hedges”) and 19.6 million shares for note hedges expiring in March 2028 (the “2028 Note Hedges”, together with the 2026 Note Hedges, the “Note Hedges”), respectively, of its Class A common stock at a price of approximately $38.25 and $35.35 per share, respectively. The aggregate cost of the convertible note hedge transactions was $265.3 million.

The Note Hedges, or a portion thereof, are exercisable upon conversion of the Notes and the satisfaction of certain conditions set forth in the Note Hedges. Additionally, the Note Hedges may be terminated and early settled upon the occurrence of certain events, including certain merger events, events of default, and upon a fundamental change (as defined in the relevant indentures for the Notes). The Note Hedges are settleable in cash, shares or a combination of cash and shares, at the option of the Company, and the settlement alternative will be the same as the settlement alternative of the conversion spread for the respective Notes.

The convertible note hedge transactions are expected generally to reduce the potential dilution to the Class A common stock upon conversion of the relevant series of Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of such converted Notes, as the case may be, in the event that the market price per share of the Class A common stock, as measured under the terms of the convertible note hedge transactions, is greater than the applicable strike price of those convertible note hedge transactions. As of June 30, 2024, the Company’s stock price was below the exercise price of the respective Note Hedges.

In addition, the Company sold warrants to certain counterparties whereby the holders of the warrants had the option to purchase a total of approximately 18.1 million shares of Class A common stock underlying such warrants expiring in 2026 (the “2026 Warrants”) and 20.1 million shares of Class A common stock underlying such warrants expiring in 2028 (the “2028 Warrants”, together with the 2026 Warrants, the “Warrants”), respectively, at an initial strike price of $46.36 and $46.36 per share, respectively. The Company received aggregate cash proceeds of $202.9 million from the sale of these Warrants.

If the market price per share of the Company’s Class A common stock, as measured under the terms of the Warrants, exceeds the strike price of the Warrants, the Warrants could have a dilutive effect, unless the Company elects, subject to certain conditions, to settle the Warrants in cash. The Warrants are only exercisable on the applicable expiration dates in accordance with the terms of the Warrants. Subject to the other terms of the Warrants, the first expiration date applicable to the 2026 Warrants and to the 2028 Warrants is June 1, 2026, and June 1, 2028, respectively, and the final expiration date applicable to the 2026 Warrants and 2028 Warrants is August 10, 2026 and August 10, 2028, respectively. As of June 30, 2024, the Company’s Class A common stock price was below the exercise price of the Warrants.

Taken together, the purchase of the Note Hedges and the sale of the Warrants are intended to reduce potential dilution from the conversion of the 2026 Notes and the 2028 Notes, and to effectively increase the overall conversion price from $38.25 per share to $46.36 per share and from $35.35 per share to $46.36 for the 2026 Notes and the 2028 Notes, respectively.

The Note Hedges and the Warrants are equity-classified instruments as a result of being indexed to the Company’s Class A common stock and meeting certain equity classification criteria, and the instruments will not be remeasured in subsequent periods as long as the instruments continue to meet these accounting criteria. The premium paid for the Note Hedges has been included as a net reduction to additional paid-in capital within stockholders’ deficit, and the premium received for the Warrants has been included as a net increase to additional paid-in capital within stockholders' deficit.

Leases [Abstract]

Leases

The Company has operating leases for corporate offices and datacenters, and finance leases for infrastructure and office equipment. The Company’s leases have remaining lease terms of under 1 year to 12 years, some of which include options to extend the leases for up to 5 years.

The Company also has subleases for several floors of its corporate offices. The Company classifies its subleases as operating leases. The subleases have remaining lease terms of 1 year to 9 years, some of which include options to extend the sublease for up to approximately 4 years. Sublease income, which is recorded as a reduction of rental expense, was $3.5 million and $7.0 million during the three and six months ended June 30, 2024, respectively, and $3.8 million and $8.2 million during the three and six months ended June 30, 2023, respectively.

Total future sublease rent payments, net	63.4

In 2017, the Company signed a 15 year lease agreement for office space in San Francisco, California, to serve as its corporate headquarters which commenced in 2018. The Company's obligations under the lease are supported by a $17.5 million letter of credit, which reduced the Company's borrowing capacity under the revolving credit facility. As of June 30, 2024, the Company's remaining minimum obligation under the lease for its headquarters was $179.5 million.

In the fourth quarter of 2020, the Company announced a Virtual First work model pursuant to which remote work has become the primary experience for all of its employees. As part of the Virtual First strategy, the Company retained a portion of its office space to be used for the Company’s team collaboration use and a portion was marketed for sublease. In connection with these changes, the Company evaluated certain of its right-of-use assets and other lease related property and equipment assets including leasehold improvements, furniture and fixtures, and computer equipment for impairment under ASC 360.

As part of this analysis, the Company reassessed its real estate asset groups and estimated the fair value of the office space to be subleased using current market conditions. Where the carrying value of the individual asset groups exceeded their fair value, an impairment charge was recognized for the difference.

During the three and six months ended June 30, 2024, the Company did not recognize any impairment charges, compared to $2.2 million during the three and six months ended June 30, 2023, related to right-of-use assets and other lease related property and equipment assets.

In the fourth quarter of 2023, the Company executed an amendment to the lease ("the lease amendment") for its San Francisco, California corporate headquarters, whereby the Company has already or will surrender to the landlord approximately 165,000 square feet of office space and pay an aggregate of $79.0 million in termination payments. The termination fees occur in three tranches: approximately 52,000 square feet and $28.1 million paid in October 2023 upon the execution of the lease amendment, 54,000 square feet and $14.9 million paid in June 2024, and the remaining 59,000 feet and $36.0 million paid in January 2025.

As of June 30, 2024, the Company had $76.2 million in commitments for leases that have not yet commenced, and therefore is not included in the right-of-use asset or lease liability. These leases will commence in 2025, with lease terms of 7 years .
