Datadog, Inc.

As required by Item 402(v) of Regulation S-K, we are providing the following information about the relationship between the compensation actually paid to our Chief Executive Officer and our other named executive officers and certain aspects of our financial performance. Compensation actually paid was calculated for purposes of this disclosure in accordance with the applicable SEC rules and does not reflect the actual amount of compensation earned by or paid to our Chief Executive Officer or our other named executive officers during the applicable years. The compensation committee does not use compensation actually paid as a basis for making compensation decisions. For information concerning how and why our compensation committee arrived at specific compensation decisions for 2025, please refer to “Executive Compensation – Compensation Discussion and Analysis.”

In the table above, grant date fair values are computed in accordance with ASC Topic 718. Stock option grant date fair values reflected in the Summary Compensation Table were estimated using the Black-Scholes option pricing model as of the date of grant. Adjustments have been made using stock option fair values as of each measurement date, which may be either year end or as of each date of vesting, using the stock price and updated assumptions as of the measurement date. Assumptions include expected term, stock price volatility, dividend yield and risk free interest rates. PSU grant date fair values reflected in the Summary Compensation Table were calculated using the stock price as of the date of grant assuming target performance. Adjustments have been made using the stock price and the probable outcome of the performance metric as of each measurement date, which may be either year end or as of each date of vesting. RSU grant date fair values reflected in the Summary Compensation Table were calculated using the stock price as of the date of grant. Adjustments have been made using the stock price as of each measurement date, which may be either year end or as of each date of vesting. The assumptions used in calculating the grant date fair value of the stock options, RSUs and PSUs are set forth in the notes to our audited consolidated financial statements included in our Annual Report on Form 10-K for each applicable year.

Analysis of Information Presented in the Pay-Versus-Performance Table

While our executive compensation program aims to provide incentives that motivate and reward achievement of our key performance goals and align our named executive officers’ interests with those of our stockholders by linking their long-term incentive compensation opportunities to stockholder value creation and their cash incentives to our annual performance, the compensation committee does not specifically select the performance measures that it uses in our executive compensation program to align with compensation actually paid, as calculated in accordance with the applicable SEC rules. Although compensation actually paid may be impacted by the performance metrics we use in our annual cash bonus plan and the design of our PSU awards, given our significant use of long-term incentive compensation, it may fluctuate significantly from year to year.

Relationship between Compensation Actually Paid and Datadog and Peer Group TSR

The following chart shows the relationships between compensation actually paid to Mr. Pomel and the average compensation actually paid to our other named executive officers as a group and the cumulative total shareholder return of our Class A common stock and the Nasdaq Computer Index for each covered fiscal year. We do not currently use total shareholder return of our Class A common stock as a financial performance measure in our executive compensation program.

Compensation Actually Paid and Net Income

The following chart shows the relationship between compensation actually paid to Mr. Pomel and the average compensation actually paid to our other named executive officers as a group and our reported net income (loss) for each covered fiscal year. We do not currently use net income (loss) as a financial performance measure in our executive compensation program.

Compensation Actually Paid and Revenue

The following chart shows the relationship between compensation actually paid to Mr. Pomel and the average compensation actually paid to our other named executive officers as a group and our reported revenue for each covered fiscal year. The growth of annual revenue is a significant performance target in the design of our PSU awards granted in 2025, 2024, 2023 and 2022 and impacts the number of shares underlying those awards that are earned. While PSU awards comprised 50% of the target value of the long-term equity compensation granted to our named executive officers in 2022, compensation actually paid decreased sharply in 2022 as the price of the shares of our Class A common stock decreased during this period. Compensation actually paid, as calculated in accordance with the applicable SEC rules, includes adjusted values to unvested and vested equity awards granted in both prior and the covered fiscal years and generally fluctuates due to our stock price.
