• Operating cash flow was $200 million, with free cash flow of $165 million.
• Cash, cash equivalents, and marketable securities were $3.9 billion as of June 30, 2025.

1) The three months ended June 30, 2025 are adjusted for M&A transaction costs of $1.4 million, and these adjustments are applied prospectively, as these costs were not material to the consolidated results of operations in the prior periods.

Second Quarter & Recent Business Highlights:

• As of June 30, 2025, we had about 3,850 customers with ARR of $100,000 or more, an increase of 14% from about 3,390 as of June 30, 2024.
• Launched its full range of products and services on the Amazon Web Services' Asia-Pacific (Sydney) Region, adding to existing locations in North America, Asia, and Europe.
• Named a Leader in the Gartner Magic Quadrant for Observability Platforms, 2025. This is the fifth consecutive year Gartner has positioned Datadog as a Leader in the Magic Quadrant.
• Joined the S&P 500 Index. The S&P 500 is widely regarded as the best single gauge of large-cap U.S. equities, tracking the stock performance of 500 leading US companies.
• Announced Datadog has ranked on the Forbes Global 2000 and Forbes Global 2000 United States Lists for 2025. Datadog's addition recognizes the company's global impact and financial strength.
• Introduced three new AI agents, Bits AI SRE, Bits AI Dev Agent and Bits AI Security Analyst agent, which perform interactive investigations and asynchronous code fixes for operations, development and security teams.
• Announced Archive Search, Flex Frozen, and CloudPrem in the log management suite, which are designed to help organizations optimize logging costs at scale and meet the stringent data retention, auditability, and data residency requirements of regulated industries.
• Launched the Internal Developer Portal, the first and only developer portal built on live observability data.
• Announced Code Security, Bits AI Security Analyst, and Workload Protection, to detect and remediate critical security risks across customers’ AI environments — from development to production — as Datadog further invests to secure its customers’ cloud and AI applications.
• Announced AI Agent Monitoring, LLM Experiments, and AI Agents Console, to give organizations end-to-end visibility, rigorous testing capabilities, and centralized governance of both in-house and third-party AI agents.
• Unveiled the first two launches from Datadog AI Research, Toto and BOOM. Toto is an open-weights model that is trained with observability data sourced exclusively from Datadog’s own internal telemetry metrics, which achieves state-of-the-art performance by a wide margin compared to all other existing time series foundation models. BOOM introduces a time series benchmark that focuses specifically on observability metrics, which contain their own challenging and unique characteristics compared to other time series.
• Announced Datadog is advancing toward Federal Risk and Authorization Management Program (FedRAMP) High authorization, which will ultimately enable federal agencies to more effectively monitor, secure, and optimize their critical applications and infrastructure while adhering to stringent compliance frameworks.

Third Quarter and Full Year 2025 Outlook:

Based on information as of today, August 7, 2025, Datadog is providing the following guidance:

• Third Quarter 2025 Outlook:
  • Revenue between $847 million and $851 million.
  • Non-GAAP operating income between $176 million and $180 million.
  • Non-GAAP net income per share between $0.44 and $0.46, assuming approximately 364 million weighted average diluted shares outstanding.
• Full Year 2025 Outlook:
  • Revenue between $3.312 billion and $3.322 billion.
  • Non-GAAP operating income between $684 million and $694 million.
  • Non-GAAP net income per share between $1.80 and $1.83, assuming approximately 364 million weighted average diluted shares outstanding.

Datadog has not reconciled its expectations as to non-GAAP operating income, or as to non-GAAP net income per share, to their most directly comparable GAAP measure as a result of uncertainty regarding, and the potential variability of, reconciling items such as stock-based compensation and employer payroll taxes on equity incentive plans. Accordingly, reconciliation is not available without unreasonable effort, although it is important to note that these factors could be material to Datadog’s results computed in accordance with GAAP.

About Non-GAAP Financial Measures

Datadog discloses the following non-GAAP financial measures in this release and the earnings call referencing this press release: non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses (research and development, sales and marketing and general and administrative), non-GAAP operating income (loss), non-GAAP operating margin, non-GAAP net income (loss), non-GAAP net income (loss) per diluted share, non-GAAP net income (loss) per basic share, free cash flow and free cash flow margin. Datadog uses each of these non-GAAP financial measures internally to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, for short- and long-term operating plans, and to evaluate Datadog’s financial performance. Datadog believes they are useful to investors, as a supplement to GAAP measures, in evaluating its operational performance, as further discussed below. Datadog’s non-GAAP financial measures may not provide information that is directly comparable to that provided by other companies in its industry, as other companies in its industry may calculate non-GAAP financial results differently, particularly related to non-recurring and unusual items. In addition, there are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies and exclude expenses that may have a material impact on Datadog’s reported financial results.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. A reconciliation of the historical non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included below in this press release.

Datadog defines non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses (research and development, sales and marketing and general and administrative), non-GAAP operating income (loss), non-GAAP operating margin and non-GAAP net income (loss) as the respective GAAP balances, adjusted for, as applicable: (1) stock-based compensation expense; (2) the amortization of acquired intangibles; (3) employer payroll taxes on employee stock transactions; (4) M&A transaction costs; (5) amortization of issuance costs; and (6) an assumed provision for income taxes based on our long-term projected tax rate. Non-GAAP financial measures prior to April 1, 2025 have not been adjusted for M&A transaction costs, as such costs were not material to our results of operations in such prior periods. Our estimated long-term projected tax rate is subject to change for a variety of reasons, including the rapidly evolving global tax environment, significant changes in Datadog's geographic earnings mix, or other changes to our strategy or business operations. We will re-evaluate our long-term projected tax rate as appropriate. Datadog defines free cash flow as net cash provided by operating activities, minus capital expenditures and minus capitalized software development costs, if any. Investors are encouraged to review the reconciliation of these historical non-GAAP financial measures to their most directly comparable GAAP financial measures.

Management believes these non-GAAP financial measures are useful to investors and others in assessing Datadog’s operating performance due to the following factors:

Stock-based compensation. Datadog utilizes stock-based compensation to attract and retain employees. It is principally aimed at aligning their interests with those of its stockholders and at long-term retention, rather than to address operational performance for any particular period. As a result, stock-based compensation expenses vary for reasons that are generally unrelated to financial and operational performance in any particular period.

Amortization of acquired intangibles. Datadog views amortization of acquired intangible assets as items arising from pre-acquisition activities determined at the time of an acquisition. While these intangible assets are evaluated for impairment regularly, amortization of the cost of acquired intangibles is an expense that is not typically affected by operations during any particular period.

Employer payroll taxes on employee stock transactions. Datadog excludes employer payroll tax expense on equity incentive plans as these expenses are tied to the exercise or vesting of underlying equity awards and the price of Datadog’s common stock at the time of vesting or exercise. As a result, these taxes may vary in any particular period independent of the financial and operating performance of Datadog’s business.

M&A transaction costs. Datadog views acquisition-related expenses, such as transaction costs, as costs that are not necessarily reflective of operational performance during a period. In particular, Datadog believes the consideration of measures that exclude such expenses can assist in the comparison of operational performance in different periods which may or may not include such expenses.

Amortization of issuance costs. In June 2020 and December 2024, Datadog issued $747.5 million of 0.125% convertible senior notes due 2025 and $1.0 billion of 0% convertible senior notes due 2029, respectively. Debt issuance costs, which reduce the carrying value of the convertible debt instrument, are amortized as interest expense over the term. The expense for the amortization of debt issuance costs is a non-cash item, and we believe the exclusion of this interest expense will provide for a more useful comparison of our operational performance in different periods.

Additionally, Datadog’s management believes that the non-GAAP financial measure free cash flow is meaningful to investors because it is a measure of liquidity that provides useful information in understanding and evaluating the strength of our liquidity and future ability to generate cash that can be used for strategic opportunities or investing in our business. Free cash flow represents net cash provided by operating activities, reduced by capital expenditures and capitalized software development costs, if any. The reduction of capital expenditures and amounts capitalized for software development facilitates comparisons of Datadog's liquidity on a period-to-period basis and excludes items that management does not consider to be indicative of our liquidity.

Operating Metrics

Datadog’s number of customers with ARR of $100,000 or more is based on the ARR of each customer, as of the last month of the quarter.

We define the number of customers as the number of accounts with a unique account identifier for which we have an active subscription in the period indicated. Users of our free trials or tier are not included in our customer count. A single organization with multiple divisions, segments or subsidiaries is generally counted as a single customer. However, in some cases where they have separate billing terms, we may count separate divisions, segments or subsidiaries as multiple customers.

We define ARR as the annualized revenue run-rate of subscription agreements from all customers at a point in time. We calculate ARR by taking the monthly recurring revenue, or MRR, and multiplying it by 12. MRR for each month is calculated by aggregating, for all customers during that month, monthly revenue from committed contractual amounts, additional usage, usage from subscriptions for a committed contractual amount of usage that is delivered as used, and monthly subscriptions. ARR and MRR should be viewed independently of revenue, and do not represent our revenue under GAAP on a monthly or annualized basis, as they are operating metrics that can be impacted by contract start and end dates and renewal rates. ARR and MRR are not intended to be replacements or forecasts of revenue.
