Marketable Securities

The following is a summary of available-for-sale marketable securities, excluding those securities classified within cash and cash equivalents on the consolidated balance sheet as of December 31, 2023 and December 31, 2022 (in thousands):

Marketable securities	$	1,555,403	$	177	$	(10,239)	$	1,545,341

Interest receivable of $15.1 million and $8.1 million is included in Prepaid expenses and other current assets on the consolidated balance sheets as of December 31, 2023 and 2022, respectively. The Company did not recognize an allowance for credit losses against interest receivable as of December 31, 2023 and 2022 because such potential losses were not material.

As of December 31, 2023, the fair values of available-for-sale marketable securities, by remaining contractual maturity, were as follows (in thousands):


Due within one year	$	1,799,542
Due in one year through five years	453,017
Total	$	2,252,559

The Company does not believe that any unrealized losses are attributable to credit-related factors based on its evaluation of available evidence. To determine whether a decline in value is related to credit loss, the Company evaluates, among other factors: the extent to which the fair value is less than the amortized cost basis, changes to the rating of the security by a rating agency and any adverse conditions specifically related to an issuer of a security or its industry. Unrealized gains and losses on marketable securities are presented net of tax.

Accounting Policies [Abstract]

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

Principles of Consolidation

The consolidated financial statements include the accounts of Datadog, Inc. and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Segment Information

The Company has a single operating and reportable segment as well as one business activity, monitoring and providing analytics on companies’ information technology (“IT”) infrastructure. 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. There are no segment managers who are held accountable for operations or results below the consolidated level.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Such estimates include the fair value of marketable securities, the allowance for credit losses, the fair value of acquired assets and assumed liabilities from business combinations, useful lives of property, equipment, software, and finite lived intangibles, stock-based compensation, valuation of long-lived assets and their recoverability, including goodwill, the incremental borrowing rate for operating leases, estimated expected period of benefit for deferred contract costs, fair value of the liability component of the convertible debt, realization of deferred tax assets and uncertain tax positions, revenue recognition and the allocation of overhead costs between cost of revenue and operating expenses. The Company bases its estimates on historical experience and also on assumptions that management considers reasonable. The Company assesses these estimates on a regular basis; however, actual results could materially differ from these estimates.

Foreign Currency Translation

The reporting currency of the Company is the United States dollar (“USD”). The functional currency of the Company is USD, and the functional currency of the Company’s subsidiaries is generally the local currency of the jurisdiction in which the foreign subsidiary is located. The assets and liabilities of the Company’s subsidiaries are translated to USD at exchange rates in effect at the balance sheet date. All income statement accounts are translated at monthly average exchange rates. Resulting foreign currency translation adjustments are recorded directly in accumulated other comprehensive loss as a separate component of stockholders’ equity.

Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in other income, net in the accompanying consolidated statements of operations when realized and have not been material for any of the periods presented.

Revenue Recognition

The Company generates revenue from the sale of subscriptions to customers using its cloud-based platform. The terms of the Company’s subscription agreements are primarily monthly, annual or multi-year. The Company’s customers can enter into (1) a subscription agreement for a committed contractual amount of usage that is apportioned ratably on a monthly basis over the term of the subscription period, (2) a subscription agreement for a committed contractual amount of usage that is delivered as used, or (3) a monthly subscription based on usage. The Company typically bills customers on an annual or multi-year subscription in advance, with any usage in excess of the committed contracted amount billed monthly in arrears. The Company typically bills customers on a monthly plan in arrears. Customers also have the option to purchase additional services priced at rates at or above the stand-alone selling price.

The Company accounts for revenue contracts with customers through the following steps:

(1)identify the contract with a customer;

(2)identify the performance obligations in the contract;

(3)determine the transaction price;

(4)allocate the transaction price to the performance obligations in the contract; and

(5)recognize revenue when or as the Company satisfies a performance obligation.

The Company’s revenue arrangements may include infrastructure monitoring, application performance monitoring, log management, synthetics monitoring, security monitoring, continuous profiling, serverless monitoring, network monitoring, real user monitoring and incident management as well as secondary services including custom metrics in dashboard monitoring, docker container monitoring, and indexed spans. The Company has identified each service as a separate performance obligation.

The transaction price is based on the fixed price for the contracted level of service plus variable consideration for additional optional purchases. Billing periods correspond to the periods over which services are performed and there are no discounts given on the purchase of future services.

The Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on a range of actual prices charged to customers.

Revenue is recognized when control of these services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those services. The Company determined an output method, recognition over time, to be the most appropriate measure of progress because it most faithfully represents when the value of the services is simultaneously received and consumed by the customer, and control is transferred.

For committed contractual amounts of usage, revenue is recognized ratably over the term of the subscription agreement generally beginning on the date that the platform is made available to a customer. For committed contractual amount of usage that is delivered as used, a monthly subscription based on usage, or usage in excess of a ratable subscription, the Company recognizes revenue as the product is used. Subscription revenue excludes sales and other indirect taxes.

The Company applied the practical expedient in Topic 606 and did not evaluate contracts of one year or less for the existence of a significant financing component.

Deferred Revenue and Remaining Performance Obligations

Certain of the Company’s customers pay in advance of satisfaction of performance obligations and other customers with monthly contract terms are billed in arrears on a monthly basis. The Company records contract liabilities to deferred revenue when customers are billed or when the Company receives customer payments in advance of the performance obligations being satisfied on the Company’s contracts.

Remaining performance obligations represent the aggregate amount of the transaction price in contracts allocated to performance obligations not delivered, or partially undelivered, as of the end of the reporting period. Remaining performance obligations include deferred revenue, multi-year contracts with future installment payments and certain unfulfilled orders against accepted customer contracts at the end of any given period.

Convertible Senior Notes

In accounting for the issuance of the Company’s convertible senior notes (the “2025 Notes”), the 2025 Notes were separated into liability and equity components through December 31, 2020. The carrying amounts of the liability component was calculated by measuring the fair value of similar liabilities that do not have associated convertible features. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the respective 2025 Notes. This difference represents the debt discount that is amortized to interest expense over the contractual terms of the 2025 Notes using the effective interest rate method. The equity component was recorded in additional paid-in capital.

In accounting for the debt issuance costs related to the 2025 Notes, the Company allocated the total amount incurred to the liability and equity components of the 2025 Notes in the same proportion as the allocation of the proceeds. Issuance costs attributable to the liability component are being amortized to interest expense over the contractual terms of the 2025 Notes. The issuance costs attributable to the equity component were netted against the equity component in additional paid-in capital.

Cost of Revenue

Cost of revenue consists primarily of costs related to providing subscription services to paying customers, including data center and networking expenses, employee compensation (including stock-based compensation) and other employee-related expenses for customer experience and technical operations staff, payments to outside service providers, payment processing fees, amortization of capitalized internally developed software costs and acquired developed technology, and allocated overhead costs.

Research and Development Costs

Research and development costs are expensed as incurred. Research and development costs consist of employee compensation (including stock-based compensation) and other employee-related expenses, materials and supplies, and allocated overhead costs such as rent and facilities costs.

Sales and Marketing Costs

Sales and marketing costs consist primarily of personnel costs for the Company’s sales and marketing organization, including stock-based compensation and commissions, costs of general marketing and promotional activities, including the free tier and introductory trials of the Company’s products, travel-related expenses, amortization of acquired customer relationships, and allocated overhead costs.

Advertising Costs

Advertising costs are expensed as incurred and were approximately $21.8 million, $25.5 million and $20.8 million for the years ended December 31, 2023, 2022 and 2021, respectively, and are included in sales and marketing expense in the accompanying consolidated statement of operations.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts for financial reporting and the tax bases of assets and liabilities. The deferred assets and liabilities are recorded at the statutorily enacted tax rates anticipated to be in effect when such temporary differences reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. A valuation allowance is established; when based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

The Company engages in transactions in which the tax consequences may be subject to uncertainty. The Company accounts for uncertain tax positions based on an evaluation as to whether it is more likely than not that a tax position will be sustained on audit, including resolution of any related appeals or litigation processes. This evaluation is based on all available evidence and assumes that the appropriate tax authorities have full knowledge of all relevant information concerning the tax position. The Company accounts for uncertain tax positions as non-current tax liabilities or through a reduction of a corresponding deferred tax asset. The tax benefit recognized is based on the largest amount that is greater than 50% likely of being realized upon ultimate settlement. The Company includes potential interest expense and penalties related to its uncertain tax positions in income tax expense.

Stock-Based Compensation

The Company recognizes and measures compensation expense for all stock-based payment awards granted to employees, directors, and nonemployees, including stock options, restricted stock units (“RSUs”), performance-based awards (“PSUs”), and the employee stock purchase plan (the “ESPP”) based on the fair value of the awards on the date of grant. The fair value of each stock option granted is estimated using the Black-Scholes option pricing model. The determination of the grant date fair value using an option-pricing model is affected by the estimated fair value of the Company’s Class A common stock as well as assumptions regarding a number of other complex and subjective variables. These variables include expected stock price volatility over the expected term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate for the expected term of the award and expected dividends. The fair value of RSUs and PSUs is determined by the closing price on the date of grant of the Company’s Class A common stock, as reported on The Nasdaq Global Select Market. The Company estimates the fair value of the rights to acquire stock under the ESPP using the Black-Scholes option pricing model. Stock-based compensation for stock options and RSUs is recognized on a straight-line basis over the requisite service period and account for forfeitures as they occur. Stock-based compensation for PSUs is amortized under the accelerated attribution method and may be adjusted over the vesting period based on interim estimates of performance against pre-set objectives. PSUs will vest upon achievement of specified performance targets and subject to continuous service through the applicable vesting dates. The compensation cost is recognized over the requisite service period when it is probable that the performance condition will be satisfied and the Company accounts for forfeitures as they occur.

The Company also has certain options that have performance-based vesting conditions; stock-based compensation expense for such awards is recognized on a straight-line basis from the time the vesting condition is likely to be met through the time the vesting condition has been achieved.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents consist of money market funds, corporate debt securities, and U.S. government treasury securities.

Marketable Securities

The Company’s marketable securities consist of corporate debt securities, commercial paper, certificates of deposit, U.S. government treasury securities, and U.S. government agency securities. The Company determines the appropriate classification of its marketable securities at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its marketable securities 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 marketable securities within current assets on the consolidated balance sheet.

Available-for-sale securities are recorded at fair value each reporting period. Premiums and discounts are amortized or accreted over the life of the related available-for-sale security as an adjustment to yield using the effective interest method. Interest income is recognized when earned. Unrealized gains and losses on these marketable securities are presented net of tax and reported as a separate component of accumulated other comprehensive loss until realized. Realized gains and losses are determined based on the specific identification method and are reported in Interest income and other income, net in the consolidated statements of operations.

The Company periodically evaluates its marketable securities to assess whether an investment’s fair value is less than its amortized cost basis and if the decline in the fair value is attributable to a credit loss. Declines in fair value judged to be related to credit loss are reported in Interest income and other income, net in the consolidated statements of operations.

Restricted Cash

Restricted cash primarily consists of collateralized letters of credit established in connection with lease agreements for the Company’s facilities. Restricted cash is included in current assets for leases that expire within one year and is included in non-current assets for leases that expire in more than one year from the balance sheet date.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to credit risk primarily consist of cash and cash equivalents, marketable securities and accounts receivable. Cash deposits may, at times, exceed amounts insured by the Federal Deposit Insurance Corporation (“FDIC”) and the Securities Investor Protection Corporation (“SIPC”). The Company has not experienced any losses on its deposits of cash and cash equivalents to date. For accounts receivable, the Company is exposed to credit risk in the event of nonpayment by customers to the extent of the amounts recorded on the accompanying consolidated balance sheets.

Fair Value of Financial Instruments

The accounting guidance for fair value provides a framework for measuring fair value, clarifies the definition of fair value, and expands disclosures regarding fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as follows:

Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

The Company’s financial instruments consist of cash equivalents, marketable securities, accounts receivable, accounts payable and accrued expenses. Cash equivalents are stated at amortized cost, which approximates fair value at the balance sheet dates, due to the short period of time to maturity. Marketable securities are recorded at fair value. Accounts receivable, accounts payable, and accrued expenses are stated at their carrying value, which approximates fair value due to the short time to the expected receipt or payment date.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable includes billed and unbilled receivables. Trade accounts receivable are recorded at invoiced amounts and do not bear interest. The expectation of collectability is based on a review of credit profiles of customers, contractual terms and conditions, current economic trends, and historical payment experience. The Company regularly reviews the adequacy of the allowance for credit losses by considering the age of each outstanding invoice and the collection history to determine the appropriate amount of allowance for credit losses. Accounts receivable deemed uncollectible are charged against the allowance for credit losses when identified.

Unbilled accounts receivable represents revenue recognized on contracts for which billings have not yet been presented to customers because the amounts were earned but not contractually billable as of the balance sheet date, substantially all of which is expected to be billed and collected within one year.

Internal Use Software Development Costs

Internal-Use Software Development Costs

The Company capitalizes qualifying internal-use software development costs related to its cloud platform. The costs consist of personnel costs (including related benefits and stock-based compensation) 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. Capitalization ceases 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.

Capitalized costs are included in property and equipment. These costs are amortized over the estimated useful life of the software, which is two years, on a straight-line basis, which represents the manner in which the expected benefit will be derived. The amortization of costs related to the platform applications is included in cost of revenue and sales and marketing expense based on an allocation between paid customer accounts and free customer accounts not generating revenue.

Property and Equipment, Net

Property and equipment, net is stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful life of the related asset. Expenses that improve an asset or extend its remaining useful life are capitalized. Costs of maintenance or repairs that do not extend the lives of the respective assets are charged to expenses as incurred.

Deferred Contract Costs

Sales commissions earned by the Company’s sales force are considered incremental and recoverable costs of obtaining a contract with a customer. There are no sales commissions earned on renewals. These costs are deferred and then amortized over a period of benefit which is determined to be 4 years. The Company determined the period of benefit by taking into consideration the length of terms in its customer contracts, life of the technology and other factors. Amounts expected to be recognized within one year of the balance sheet date are recorded as deferred contract costs, current; the remaining portion is recorded as deferred contract costs, non-current, in the consolidated balance sheets. Deferred contract costs are periodically analyzed for impairment. Amortization expense is included in sales and marketing expenses in the accompanying consolidated statements of operations.

Business Combinations

When the Company acquires a business, the purchase consideration is allocated to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated respective fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require the Company to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired users, acquired technology, and trade names from a market participant perspective, useful lives and discount rates. The Company’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to other income, net in the consolidated statement of operations.

Accounting for Impairment of Long-Lived Assets (Including Goodwill and Intangibles)

Long-lived assets with finite lives include property and equipment, capitalized development software costs and acquired intangible assets. Long-lived assets are amortized over their estimated useful lives which are as follows:


Computers and equipment			3 years
Furniture and fixtures			5 years
Leasehold improvements			Shorter of lease term or useful life of asset
Capitalized software development costs			2 years
Developed technology			3 years
Customer relationships			4 years

The Company evaluates long lived assets, including acquired intangible assets and capitalized software development costs, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable or the estimated useful life becomes shorter than originally estimated. Recoverability of assets held and used is measured by comparison of the carrying amount of an asset or an asset group to estimated undiscounted future net cash flows expected to be generated by the asset or asset group. If the carrying amount of an asset exceeds these estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the assets exceeds the fair value of the asset or asset group, based on discounted cash flows.

Goodwill is not amortized but rather tested for impairment at least annually on October 1, or more frequently if events or changes in circumstances indicate that goodwill may be impaired. Goodwill impairment is recognized when the quantitative assessment results in the carrying value exceeding the fair value, in which case an impairment charge is recorded to the extent the carrying value exceeds the fair value. The Company did not recognize any impairment of goodwill during the years ended December 31, 2023, 2022 or 2021.

Operating Leases

The Company determines if an arrangement is a lease at inception. Operating lease assets and liabilities are reflected within operating lease assets, operating lease liabilities, current, and operating lease liabilities, non-current, on the consolidated balance sheets. For short-term leases (an initial term of 12 months or less), an operating lease asset and corresponding lease liability are not recorded and the Company records rent expense in its consolidated statements of operations on a straight-line basis over the lease term. Operating lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company generally uses its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The operating lease assets also include any lease payments made and excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for separately.

Net Income (Loss) Per Share Attributable to Common Shareholders

Net Income (Loss) Per Share Attributable to Common Stockholders

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of Class A common stock and Class B common stock (together “common stock”) outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding during the period giving effect to all potentially dilutive securities to the extent they are dilutive. The dilutive effect of potentially dilutive securities is reflected in diluted net income (loss) per share by application of the two-class method. During the periods when the Company is in a net loss position, the net loss attributable to common stockholders was not allocated to the unvested common stock under the two-class method as these securities do not have a contractual obligation to share in the Company’s losses.

Accounting Pronouncements Recently Adopted / Not yet Adopted

Accounting Pronouncements Recently Adopted

In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU No. 2021-08”), which intends to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. It is effective for interim and annual periods beginning after December 15, 2022, with early adoption permitted. The Company early adopted ASU No. 2021-08 on January 1, 2022 on a prospective basis with no material impact on the Company's consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU No. 2023-07”), which intends to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this ASU should be applied retrospectively to all prior

periods presented in the financial statements. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU No. 2023-09”), which intends to increase the transparency of income tax disclosures, particularly the rate reconciliation table and disclosures about income taxes paid. For public business entities, it is effective for annual periods beginning after December 15, 2024, and interim periods beginning after December 15, 2025, with early adoption permitted. The Company has not early adopted ASU No. 2023-09 as of December 31, 2023 and is evaluating its impact.

Net Income (Loss) Per Share

12 Months Ended

Dec. 31, 2023

Earnings Per Share [Abstract]

Net Income (Loss) Per Share

Basic and diluted net income (loss) per common share is presented in conformity with the two-class method required for participating securities. Immediately prior to the consummation of the Company’s IPO in September 2019, all outstanding shares of convertible preferred stock and common stock were converted into shares of Class B common stock. As a result, Class A and Class B common stock are the only outstanding equity in the Company.

Basic and diluted net income (loss) per share is computed using the weighted-average number of common shares of common stock outstanding during the period. The undistributed earnings are allocated based on the contractual participation rights of the Class A and Class B common stock as if the earnings for the year have been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis. Further, as the conversion of Class B common stock is assumed in the computation of the diluted net loss per share of Class A common stock, the undistributed earnings are equal to net loss for that computation.

The following table presents the calculation of basic and diluted net income (loss) per share (in thousands, except per share data):

For the periods presented where the Company was in a loss position, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been anti-dilutive. Potentially dilutive securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows (in thousands):

ASU No. 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share when the instruments may be settled in cash or shares. See Note 2, Basis of

Presentation and Summary of Significant Accounting Policies—Accounting Policies Recently Adopted for more information. During the three months ended December 31, 2023, the conditional conversion feature of the 2025 Notes was not triggered and the 2025 Notes are not convertible, in whole or in part, at the option of the holders between January 1, 2024 through March 31, 2024. The Company uses the if-converted method for calculating any potential dilutive effect of the conversion options embedded in the 2025 Notes on diluted net income per share; however, since the Company is in a net loss position, there was no dilutive effect during any period presented.

The Company entered into Capped Calls in connection with the issuance of the 2025 Notes. The effect of the Capped Calls was also excluded from the calculation of diluted net income per share as the effect of the Capped Calls would have been anti-dilutive. The Capped Calls are expected to partially offset the potential dilution to the Company’s Class A common stock upon any conversion of the 2025 Notes.

Convertible Senior Notes

12 Months Ended

Dec. 31, 2023

Debt Disclosure [Abstract]

Convertible Senior Notes

On June 2, 2020, the Company issued $747.5 million aggregate principal amount of 0.125% convertible senior notes due 2025 (the “2025 Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (“Securities Act”). The total net proceeds from the sale of the 2025 Notes, after deducting the initial purchasers’ discounts and debt issuance costs, were approximately $730.2 million. The 2025 Notes bear interest at a rate of 0.125% per year, payable semiannually in arrears on June 15 and December 15 of each year, beginning on December 15, 2020. The 2025 Notes will mature on June 15, 2025, unless earlier converted, redeemed or repurchased.

Holders may convert their notes at their option at any time prior to the close of business on the business day immediately preceding March 15, 2025 only under the following circumstances:

(1)during any calendar quarter commencing after the calendar quarter ending on September 30, 2020 (and only during such calendar quarter), if the last reported sale price of the Company’s Class A common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

(2)during the five business day period after any ten consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of 2025 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s Class A common stock and the conversion rate on each such trading day;

(3)if the Company calls such 2025 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or

(4)upon the occurrence of specified corporate events, as set forth in the indenture governing the 2025 Notes (“the Indenture”).

On or after March 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes, in integral multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. The conversion rate for the 2025 Notes is initially 10.8338 shares of Class A common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $92.30 per share of Class A common stock), subject to adjustment as set forth in the Indenture. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at the Company’s election. If the Company satisfies its conversion obligation solely in cash or through payment and delivery, as the case may be, of a combination of cash and shares of Class A common stock, the amount of cash and shares of Class A common stock, if any, due upon conversion will be based on a daily conversion value calculated on a proportionate basis for each trading day in a 30 trading day observation period as described in the Indenture. In addition, if specific corporate events occur prior to the applicable maturity date, or if the Company elects to redeem the 2025 Notes, the Company will increase the conversion rate for a holder who elects to convert their notes in connection with such a corporate event or redemption in certain circumstances.

During the three months ended December 31, 2023, the conditional conversion feature of the 2025 Notes was not triggered as the last reported sale price of the Company’s Class A common stock was not greater than or equal to 130% of the conversion price for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the quarter ended December 31, 2023. Therefore the 2025 Notes are not convertible, in whole or in part, at the option of the holders between January 1, 2024 through March 31, 2024. Whether the 2025 Notes will be convertible in future periods will depend on the continued satisfaction of this condition or another conversion condition.

When a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. Since the issuance of the 2025 Notes, the Company received and settled an immaterial amount of conversion notices from the holders in cash. As of December 31, 2023, the 2025 Notes were classified as long-term debt on the Company's consolidated balance sheet.

The Company may redeem for cash all or any portion of the 2025 Notes prior to the 31st scheduled trading day immediately preceding the maturity date, at its option, if the last reported sale price of its Class A common stock was at least 130% of the conversion price 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 a notice of redemption at a redemption price equal to 100% of the principal amount of the 2025 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

In accounting for the issuance of the 2025 Notes, the 2025 Notes were separated into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of similar liabilities that do not have associated convertible features. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the respective 2025 Notes. This difference represents the debt discount that is amortized to interest expense over the contractual terms of the 2025 Notes using the effective interest rate method. The carrying amount of the equity component representing the conversion option was $177.2 million. The equity component was recorded in additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification.

In accounting for the debt issuance costs of $17.3 million related to the 2025 Notes, the Company allocated the total amount incurred to the liability and equity components of the 2025 Notes in the same proportion as the allocation of the proceeds. Issuance costs attributable to the liability component were $13.2 million and will be amortized, along with the debt discount, to interest expense over the contractual term of the 2025 Notes at an effective interest rate of 5.97%. Issuance costs attributable to the equity component were $4.1 million and are netted against the equity component in additional paid-in capital.

On January 1, 2021 the Company adopted ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. As a result of the adoption, the debt conversion option of $177.2 million and debt issuance costs of $4.1 million previously attributable to the equity component are no longer presented in equity. Similarly, the debt discount, that is equal to the carrying value of the embedded conversion feature upon issuance, is no longer amortized into income as interest expense over the life of the instrument. This resulted in a $16.8 million decrease to the opening balance of accumulated deficit, a $173.1 million decrease to the opening balance of additional paid-in capital and a $156.3 million increase to the opening balance of convertible senior notes, net on the consolidated balance sheet.

The net carrying amount of the liability component of the 2025 Notes was as follows (in thousands):


	December 31, 2023		December 31, 2022
Convertible senior notes, net:
Principal	$	747,496	$	747,496
Unamortized debt issuance costs	(5,261)		(8,649)
Net carrying amount	$	742,235	$	738,847

As of December 31, 2023, the total estimated fair value of the 2025 Notes was approximately $1,050.2 million. The fair value was determined based on the closing trading price or quoted market price per $100 of the 2025 Notes as of the last day of trading for the period. The fair value of the 2025 Notes is primarily affected by the trading price of the Company’s Class A common stock and market interest rates.

The following table sets forth the interest expense related to the 2025 Notes for the years ended December 31, 2023, 2022, and 2021 (in thousands):


	Year Ended December 31,
	2023		2022		2021
Contractual interest expense	$	934	$	934	$	934
Amortization of issuance costs	3,388		3,369		3,349
Total	$	4,322	$	4,303	$	4,283

Capped Calls

In connection with the pricing of the 2025 Notes, the Company entered into privately negotiated capped call transactions with certain counterparties (“Capped Calls”). The Capped Calls each have an initial strike price of approximately $92.30 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2025 Notes. The Capped Calls have initial cap prices of $151.04 per share, subject to certain adjustments. The Capped Calls are expected to partially offset the potential dilution to the Company’s Class A common stock upon any conversion of the 2025 Notes, with such offset subject to a cap based on the cap price. The Capped Calls cover, subject to anti-dilution adjustments, approximately 8.1 million shares of the Company’s Class A common stock. For accounting purposes, the Capped Calls are separate transactions, and not part of the 2025 Notes. As these transactions meet certain accounting criteria, the Capped Calls are recorded in stockholders' equity and are not accounted for as derivatives. The cost of $89.6 million incurred to purchase the Capped Calls was recorded as a reduction to additional paid-in capital and will not be remeasured.

The Company considers all highly liquid investments, including money market funds with an original maturity of three months or less at the date of purchase, to be cash equivalents. The Company uses quoted prices in active markets for assets to determine the fair value of its Level 1 investments in money market funds. The Company classifies its commercial paper, corporate debt securities, certificates of deposit, U.S. government treasury securities, and Non-U.S. government securities within Level 2 because they are valued using inputs other than quoted prices that are directly or indirectly observable in the market, including readily available pricing sources for the identical underlying security which may not be actively traded.

In addition to its cash equivalents and marketable securities, the Company measures the fair value of its outstanding convertible senior notes on a quarterly basis for disclosure purposes. The Company considers the fair value of the convertible senior notes to be a Level 2 measurement due to limited trading activity of the convertible senior notes. Refer to Note 8, Convertible Senior Notes, to the consolidated financial statements for further details.

- 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.

Employee Stock Purchase Plan

In September 2019, the Board adopted and approved the 2019 ESPP, which became effective on the date of the final prospectus for the Company’s IPO.

The ESPP is implemented through a series of offerings under which eligible employees are granted purchase rights to purchase shares of the Company’s Class A common stock on specified dates during such offerings. Under the ESPP, the Company may specify offerings with durations of not more than 27 months and may specify shorter purchase periods within each offering. Historically offering periods have been approximately 6 months. On each purchase date, eligible employees will purchase the shares at a price per share equal to 85% of the lesser of (1) the fair market value of the Company’s Class A common stock on the first trading day of the offering period, or (2) the fair market value of the Company’s Class A common stock on the purchase date, as defined in the ESPP.

The Company recognized $16.0 million, $11.2 million, and $7.6 million of stock-based compensation expense related to the ESPP during the years ended December 31, 2023, 2022, and 2021, respectively.

As of December 31, 2023, and 2022, $6.6 million and $6.0 million, respectively has been withheld on behalf of employees for a future purchase under the ESPP due to the timing of payroll deductions.

During the years ended December 31, 2023, 2022, and 2021, the Company issued 517,430, 316,875, and 291,871 shares of Class A common stock under the ESPP. As of December 31, 2023, 17,481,059 shares of Class A common stock remain available for grant under the ESPP.

Total compensation cost related to the ESPP not yet recognized was approximately $6.8 million and $7.1 million as of December 31, 2023 and 2022, respectively. The weighted average period over which this compensation cost will be recognized is 0.4 years as of December 31, 2023 and 2022, respectively.

Certain reclassifications have been made to the components of Tax Rate Reconciliation for the year ending December 31, 2022 and 2021 to conform to the 2023 presentation.

For the year ended December 31, 2023, the Company has evaluated the available evidence supporting the realization of its deferred tax assets, including the amount and timing of future taxable income, and has determined that it is more likely than not that its net deferred tax assets will not be realized in the United States. Due to uncertainties surrounding the realization of the deferred tax assets, the Company recorded a full valuation allowance against substantially all of its net deferred tax assets. When the Company determines that it will be able to realize some portion or all of its deferred tax assets, an adjustment to its valuation allowance on its deferred tax assets would have the effect of increasing net income in the period such determination is made.

The Company is subject to tax laws in the United States and numerous foreign jurisdictions. The United States and many international legislative and regulatory bodies continually propose and enact legislation that could significantly impact how U.S. multinational corporations are taxed. The Company is closely monitoring proposed legislation and its potential impact. For tax years beginning on or after January 1, 2022, the Tax Cuts and Jobs Act of 2017 eliminates the option to deduct research and development expenditures, as defined under IRC Section 174, in the year incurred. Instead, taxpayers are required to amortize such expenditures over five years if incurred in the U.S. and over fifteen years if incurred in a foreign jurisdiction.


	December 31,
	2023		2022
Deferred tax assets:
Net operating losses	$	49,057	$	54,974
U.S. R&D tax credits	46,639		13,841
Stock-based compensation	47,652		48,872
Section 174 capitalization	181,721		76,625
Lease liability	27,004		18,793
Other	21,593		15,494
Total deferred tax assets	$	373,666	$	228,599
Less: valuation allowance	(321,612)		(188,817)
Deferred tax assets, net of valuation allowance	$	52,054	$	39,782
Deferred tax liabilities:
Commissions	(29,782)		(22,182)
Right of use asset	(20,916)		(17,151)
Total deferred tax liabilities	$	(50,698)	$	(39,333)
Deferred tax assets, net	$	1,356	$	449

The Company accounts for income taxes using an asset and liability method and deferred income tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets and liabilities are expected to be realized or settled. The Company’s deferred tax assets and liabilities consist primarily of federal and state net operating loss carryforwards and basis differences for financial reporting and tax purposes of certain assets and liabilities. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based upon the weight of all available evidence, which includes the historical operating performance and the recorded cumulative losses in prior fiscal periods, management does not believe as of December 31, 2023 and 2022 that it is more likely than not that the Company will realize its U.S. deferred tax assets. As a result, a valuation allowance of $321.6 million and $188.8 million has been provided at December 31, 2023 and 2022, respectively. The valuation allowance changed by $132.8 million and $40.2 million at December 31, 2023 and 2022, respectively. Certain reclassifications have been made to the components of deferred tax for the year ending December 31, 2022 to conform to the 2023 presentation.

At December 31, 2023 and 2022, the Company has net operating loss carryforwards for federal tax purposes of approximately $148.9 million and $243.4 million, respectively, which is available to offset federal taxable income. The federal net operating loss carryforwards generated at December 31, 2017 and prior will begin to expire in 2031, if not utilized. Net operating losses generated after December 31, 2017 have an indefinite carryforward period but are subject to an 80% of taxable income limitation after December 31, 2020. The Company has approximately $206.4 million and $92.0 million of post-apportioned net operating loss carryforwards as of December 31, 2023 and 2022, respectively for various state tax purposes. The state net operating loss carryforwards will begin to expire in 2026, if not utilized.

Generally, the utilization of net operating losses may be subject to an annual limitation provided for in the Internal Revenue Code of 1986, as amended, under Section 382 and similar state codes. The Company has prepared an analysis to determine whether its net operating losses may be limited under such provisions. It has been determined that any annual limitation would not result in the expiration of net operating loss carryforwards before utilization.

In general, it is the practice and intention of the Company to reinvest the earnings of its non-U.S. subsidiaries in those operations. Historically, the Company has not made a provision for U.S. income tax with respect to accumulated earnings of foreign subsidiaries where the foreign investment of such earnings is essentially permanent in duration. Generally, such amounts would become subject to U.S. taxation upon the remittance of dividends and under certain other circumstances. The Company has not provided U.S. taxes on unremitted earnings of its foreign subsidiaries as it asserts permanent reinvestment on any accumulated earnings and profits.

Consistent with the provisions of ASC 740, Income Taxes, 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.

The following table shows the changes in the gross amount of unrecognized tax benefits as of December 31, 2023, 2022 and 2021 (in thousands):


	December 31,
	2023		2022		2021
Beginning balance	$	106	$	106	$	532
Increases based on tax positions during the current period	—		—		—
(Decreases) based on tax positions during the current period	(47)		—		(426)
Ending balance	$	59	$	106	$	106

The total amount of unrecognized tax benefits that, if recognized would impact the effective tax rate would be $0.1 million for the year ended December 31, 2023.

The Company’s policy for classifying interest and penalties associated with unrecognized income tax benefits is to include such items in income tax expense. The total amount of interest and penalties associated with unrecognized income tax benefits is $0.1 million and $0.1 million for the years ended December 31, 2023 and 2022.

It is reasonably possible that certain unrecognized tax benefits may increase or decrease within the next 12 months due to tax examination changes, settlement activities, expirations of statute of limitations, or the impact on recognition and measurement considerations related to the results of published tax cases or other similar activities. As such the Company anticipates insignificant changes to unrecognized tax benefits over the next 12 months.

The Company files income tax returns in the U.S. federal jurisdiction, various state jurisdictions and in various international jurisdictions. Tax years 2017 and forward generally remain open for examination for federal and state tax purposes. To the extent utilized in future years’ tax returns, net operating loss carryforwards at December 31, 2023 and 2022 will remain subject to examination until the respective tax year is closed.

Accounting Policies [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

Principles of Consolidation

The consolidated financial statements include the accounts of Datadog, Inc. and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Segment Information

Use of Estimates

Foreign Currency Translation

Revenue Recognition

The Company accounts for revenue contracts with customers through the following steps:

(1)identify the contract with a customer;

(2)identify the performance obligations in the contract;

(3)determine the transaction price;

(4)allocate the transaction price to the performance obligations in the contract; and

(5)recognize revenue when or as the Company satisfies a performance obligation.

The Company applied the practical expedient in Topic 606 and did not evaluate contracts of one year or less for the existence of a significant financing component.

Deferred Revenue and Remaining Performance Obligations

Convertible Senior Notes

On January 1, 2021, the Company adopted ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU No. 2020-06”). As a result of the adoption, the debt conversion option of $177.2 million and debt issuance costs of $4.1 million previously attributable to the equity component are no longer presented in equity. Similarly, the debt discount, that is equal to the carrying value of the embedded conversion feature upon issuance, is no longer amortized into income as interest expense over the life of the instrument. This resulted in a $16.8 million decrease to the opening balance of accumulated deficit, a $173.1 million decrease to the opening balance of additional paid-in capital and a $156.3 million increase to the opening balance of convertible senior notes, net on the consolidated balance sheet.

North America (1)	$	1,487,319	$	1,200,719	$	736,218
International	641,040		474,381		292,566
Total	$	2,128,359	$	1,675,100	$	1,028,784

1)Includes revenue from the United States of $1,411.0 million, $1,134.1 million, and $691.8 million for the years ended December 31, 2023, 2022, and 2021, respectively.

Other than the United States, no other individual country accounted for 10% or more of total revenue for the years ended December 31, 2023, 2022, or 2021.

Accounts Receivable

As of December 31, 2023 and 2022, unbilled accounts receivable of approximately $61.2 million and $60.0 million, respectively, was included in accounts receivable on the Company’s consolidated balance sheets.

During the years ended December 31, 2023 and 2022, the Company charged $5.5 million and $2.7 million, respectively, of accounts receivable deemed uncollectible against the allowance for credit losses.

Deferred Revenue and Remaining Performance Obligations

Revenue recognized during the years ended December 31, 2023, 2022 and 2021 which was included in the deferred revenue balances at the beginning of each respective period, was $525.5 million, $374.6 million, and $206.6 million.

As of December 31, 2023, and 2022, the aggregate transaction price allocated to remaining performance obligations was $1,839.4 million and $1,057.2 million, respectively.
