These forward-looking statements include, but are not limited to, statements concerning the following:
•our expectations regarding our revenue, expenses and other operating results;
•our ability to acquire new customers and successfully retain existing customers;
•our ability to increase usage of our platform and upsell and cross sell additional products;

You should not rely on forward-looking statements as predictions of future events. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties and other factors described under the header “Risk Factors” and elsewhere in this Quarterly Report on Form 10-Q. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained herein. The results, events and circumstances reflected in the forward-looking statements may not be achieved or occur, and actual results, events or circumstances could differ materially from those described in the forward-looking statements.
The forward-looking statements made in this Quarterly Report on Form 10-Q relate only to events as of the date on which the statements are made, and we undertake no obligation to update them to reflect events or circumstances after the date of this Quarterly Report on Form 10-Q or to reflect new information or the occurrence of unanticipated events, except as required by law.

DATADOG, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
1. Organization and Description of Business
Description of Business
Datadog, Inc. (“Datadog” or the “Company”) was incorporated in the State of Delaware on June 4, 2010. The Company is the monitoring and analytics platform for developers, IT operations teams and business users in the cloud age. The Company’s SaaS platform integrates and automates infrastructure monitoring, application performance monitoring, log management and security monitoring to provide unified, real-time observability of its customers’ entire technology stack. The Company is headquartered in New York City and has various other global office locations.
2. Basis of Presentation and Summary of Significant Accounting Policies
Unaudited Interim Condensed Consolidated Financial Information
The unaudited condensed consolidated financial statements include the accounts of Datadog, Inc. and its wholly-owned subsidiaries, and have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and following the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted. These financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair statement of the Company’s financial information. These interim results are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2021 or for any other interim period or for any other future year. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as filed with the SEC on March 1, 2021 (the “Annual Report”).
Basis of Presentation
The accompanying condensed consolidated financial statements have been prepared in accordance with GAAP.
Principles of Consolidation
The condensed consolidated financial statements include the accounts of Datadog, Inc. and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed 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.
Accounting Pronouncements Recently Adopted
In August 2020, the Financial Accounting Standards Board ("FASB") issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU No. 2020-06”), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity's own equity. Among other changes, ASU No. 2020-06 removes from GAAP the liability and equity separation model for
9

convertible instruments with a cash conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such convertible debt instruments. Similarly, the debt discount, that is equal to the carrying value of the embedded conversion feature upon issuance, will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. Among other potential impacts, this change is expected to reduce reported interest expense, increase reported net income and result in a reclassification of certain conversion feature balance sheet amounts from stockholders’ equity to liabilities. Additionally, ASU No. 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share and include the effect of share settlement for instruments that may be settled in cash or shares, except for certain liability-classified share-based payment awards. ASU No. 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020 and can be adopted on either a fully retrospective or modified retrospective basis. The Company early adopted ASU No. 2020-06 on January 1, 2021, using the modified retrospective basis. Adoption 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 condensed consolidated balance sheet.

3. Marketable Securities
The following is a summary of available-for-sale marketable securities, excluding those securities classified within cash and cash equivalents on the condensed consolidated balance sheets as of September 30, 2021 and December 31, 2020 (in thousands):

As of September 30, 2021, the fair values of available-for-sale marketable securities, by remaining contractual maturity, were as follows (in thousands):
Due within one year$678,149 
Due in one year through five years502,011 
Total$1,180,160 
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.

4. Fair Value Measurements
The following tables present information about the Company’s financial assets and liabilities that have been measured at fair value on a recurring basis as of September 30, 2021 and December 31, 2020, and indicate the fair value hierarchy of the valuation inputs utilized to determine such fair value (in thousands):

Total financial assets$181,743 $1,317,727 $— $1,499,470 
The Company classifies its highly liquid money market funds within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets. The Company classifies its commercial paper, corporate debt securities, certificates of deposit and U.S. government treasury 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 7, Convertible Senior Notes, to the condensed consolidated financial statements for further details.

Depreciation and amortization expense was approximately $3.7 million and $10.7 million for the three and nine months ended September 30, 2020, respectively.
6. Acquisitions, Intangible Assets and Goodwill
2021 Acquisitions
In April 2021, the Company entered into a Stock Purchase Agreement whereby the Company acquired all of the issued and outstanding shares of a SaaS based security platform company. The consideration was approximately $219.4 million, comprising cash and Class A common stock. The acquisition was accounted for as a business combination in accordance with ASC 805, Business Combinations, and accordingly, the total fair value of the purchase consideration was allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values on the acquisition date. The total preliminary purchase price allocated to intangible assets and goodwill was $12.0 million and $204.3 million, respectively. The resulting goodwill is not deductible for income tax purposes. Intangible assets consisted of developed technology in the amount of $8.7 million and customer relationships in the amount of $3.3 million. The useful life for developed technology and customer relationships are three and four years, respectively. Additionally, there was a one-time severance charge of $1.3 million recorded on the acquisition date.

The purchase price allocation is preliminary. The Company continues to collect information with regard to its estimates and assumptions, including potential liabilities and contingencies. The Company will record adjustments to the fair value of the assets acquired, liabilities assumed and goodwill within the 12 month measurement period, if necessary. Goodwill resulted primarily from the expectation of enhancing the Company's current application security tools. Pro forma results of operations for this acquisition have not been presented because they were not material to the condensed consolidated results of operations.

7. 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
13

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 September 30, 2021, the conditional conversion feature of the 2025 Notes was triggered as 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 quarter ended September 30, 2021 was greater than or equal to 130% of the conversion price on each applicable trading day. Therefore the 2025 Notes are convertible, in whole or in part, at the option of the holders between October 1, 2021 through December 31, 2021. Whether the 2025 Notes will be convertible following such period will depend on the continued satisfaction of this condition or another conversion condition in the future.

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. As of September 30, 2021, the 2025 Notes were classified as long-term debt on the Company's condensed consolidated balance sheet.
The Company may not redeem the 2025 Notes prior to June 20, 2023. On or after June 20, 2023, and prior to the 31st scheduled trading day immediately preceding the maturity date, the Company may redeem for cash all or any portion of the 2025 Notes, 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 through December 31, 2020. 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 was amortized to interest expense 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.
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 to interest expense
14

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 condensed consolidated balance sheet.

As of September 30, 2021, the total estimated fair value of the 2025 Notes was approximately $1,237.1 million. The fair value was determined based on the closing trading 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.
