NEW YORK, Aug. 05, 2021 (GLOBE NEWSWIRE) -- Datadog, Inc. (NASDAQ:DDOG), the monitoring and security platform for cloud applications, today announced financial results for its second quarter ended June 30, 2021.

"We had a strong second quarter, with revenue growth accelerating to 67% year-over-year and 18% quarter-over-quarter. We saw broad-based strength across customer segments and products," said Olivier Pomel, co-founder and CEO of Datadog. "Our high growth at scale demonstrates that we continue to be a trusted partner in our customers' digital transformation and cloud migration journeys."

Pomel added, "We continue to expand the features and functionality of our cloud native end-to-end observability platform. Meanwhile, we are just getting started on our journey to break down silos between DevOps and Security teams with our Cloud Security Platform."

Second Quarter 2021 Financial Highlights:

• Revenue was $233.5 million, an increase of 67% year-over-year.

• GAAP operating loss was $(9.9) million; GAAP operating margin was (4)%.

• Non-GAAP operating income was $30.9 million; non-GAAP operating margin was 13%.

• GAAP net loss per diluted share was $(0.03); non-GAAP net income per diluted share was $0.09.

• Operating cash flow was $51.7 million, with free cash flow of $42.3 million.

• Cash, cash equivalents, restricted cash, and marketable securities were $1.4 billion as of June 30, 2021.

Second Quarter & Recent Business Highlights:

• As of June 30, 2021, we had 1,610 customers with ARR of $100,000 or more, an increase of 59% from 1,015 as of June 30, 2020.

• Announced the launch of the Datadog Cloud Security Platform, adding full-stack security context to Datadog's deep observability capabilities. This new offering enables organizations to use a single platform to correlate security insights with monitoring data across infrastructure, network and application tiers, providing Security teams with the visibility they need to understand and respond to potential threats faster. The Cloud Security Platform includes Cloud Security Posture Management, Cloud Workload Security, Security Monitoring, and Application Security (in beta), as well as Unified Observability and Security Reporting capabilities.

• Cloud Security Posture Management (CSPM) and Cloud Workload Security (CWS) became generally available. Cloud Security Posture Management (CSPM) makes it easy to track whether production environments comply with industry standards. Cloud Workload Security (CWS) detects threats to production workloads by monitoring file and process activity across environments to help catch host and infrastructure-based attacks.

• Announced the beta launch of CI Visibility, a way to bring production level visibility earlier into the development process by shifting left and bringing observability throughout the CI/CD pipeline.

• Announced support for application monitoring with AWS App Runner, joining Amazon Web Services (AWS) as a Launch Partner for the new fully managed service. This new functionality will help engineering and product teams scale, deploy, and monitor their apps without the burden of managing their own infrastructure.

• Announced the general availability of Datadog’s AWS Lambda extension. This feature enables engineering teams to send their metrics, traces, and logs securely to Datadog with minimal overhead to their business-critical serverless applications.

• Announced our integration with the Salesforce platform. This new integration provides Salesforce admins and security teams with the ability to detect and respond to suspicious behavior through visibility into user, platform and API activity.

• Achieved Amazon Web Services (AWS) Government Competency status. This designation reflects Datadog's deep experience working with government customers to deliver mission-critical workloads and applications on AWS.

• Announced availability on the Google Cloud Marketplace. Google Cloud customers can now purchase Datadog with just a few clicks on the Google Cloud Marketplace, allowing them to quickly and easily monitor the health of their applications and infrastructure across their Google Cloud and hybrid cloud environments.

• Delivered numerous product innovations, including cross-browser testing in Synthetics; support for Android, iOS, and cross-platform frameworks like React Native in mobile RUM; automatic detection of faulty deployments in APM; and anomaly detection in Security Monitoring.

Third Quarter and Full Year 2021 Outlook:

Based on information as of today, August 5, 2021, Datadog is providing the following guidance:

• Third Quarter 2021 Outlook:

  • Revenue between $246 million and $248 million.

  • Non-GAAP operating income between $18 million and $20 million.

  • Non-GAAP net income per share between $0.05 and $0.06, assuming approximately 344 million weighted average diluted shares outstanding.

• Full Year 2021 Outlook:

  • Revenue between $938 million and $944 million.

  • Non-GAAP operating income between $87 million and $93 million.

  • Non-GAAP net income per share between $0.26 and $0.28, assuming approximately 344 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 (sales and marketing, research and development, 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, and free cash flow. 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 (sales and marketing, research and development, 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) non-cash benefit related to tax adjustment; (4) employer payroll taxes on employee stock transactions; and (5) amortization of issuance costs. Datadog defines free cash flow as Net cash provided by operating activities, minus capital expenditures and minus capitalized software development costs. 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.

Non-cash benefit related to tax adjustment. Datadog recorded a contingent payroll tax liability in conjunction with a common stock repurchase transaction in 2016. In 2020, the period of limitations for assessing the contingent Federal payroll tax liability expired and the Company was legally released from being the primary obligor, and recognized a benefit in the consolidated statement of operations. Datadog does not believe this is reflective of on-going results and therefore adjusted for this benefit.

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.

Amortization of issuance costs. In May 2020, Datadog issued $747.5M of convertible senior notes due 2025, which bear interest at an annual fixed rate of 0.125%. 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 management reviews cash flows generated from operations after taking into consideration capital expenditures and the capitalization of software development costs due to the fact that these expenditures are considered to be a necessary component of ongoing operations.

Operating Metrics

Datadog’s number of customers with ARR of $100,000 or more and number of customers with ARR of $1 million or more are 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. 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 is defined as the revenue run-rate of subscription agreements from all customers for the last month of the period, including committed amounts and any additional usage. ARR and MRR should be viewed independently of revenue as they are operating metrics and are not intended to be replacements or forecasts of revenue.
