Key Highlights

  • Q2 2026 Revenue rose 36% to $1.12 billion and non-GAAP EPS was $0.65, both ahead of consensus, while customers with $100,000+ ARR grew 23% to about 4,720.
  • Q3 revenue guidance of $1.135 billion to $1.145 billion implied under 2% sequential growth, and the stock fell about 17% from near $292.
  • The shares closed at $230.27 on Sep 15; CPO Yanbing Li sold 12,700 shares on Sep 11 under a 10b5-1 plan.
  • Full-year 2026 guidance was raised to revenue of $4.45 billion to $4.47 billion and non-GAAP EPS of $2.50 to $2.54, even as the free Cash Flow Margin slipped to about 25% from about 29%.

Datadog, Inc. (NASDAQ:DDOG) shares are struggling to recover because investors focused on the company's outlook more than on its strong second-quarter results. On Aug 6, 2026, the cloud monitoring and security company reported revenue up 36% to $1.12 billion and raised its full-year forecast. But its third-quarter revenue guidance of $1.135 billion to $1.145 billion sat only slightly above the quarter just reported, suggesting sequential growth of less than 2% at the midpoint. The stock fell about 17%, from near $292 before the report to the mid-$230s.

Six weeks later, the shares have yet to regain that ground. The stock closed at $230.27 on Sep 15. Several days earlier, Chief Product Officer Yanbing Li sold 12,700 shares at a weighted average price of $221.26, a price below the immediate post-earnings level.

The pressure appears to reflect a combination of factors rather than a single problem: the modest sequential guidance, a lower free cash flow margin and valuation concerns after a strong run in the shares earlier in 2026. None of these points to a sudden deterioration in the business, but together they have given investors reasons to wait for more evidence before paying the prices seen before the report.

The Quarter Behind the Selloff

The headline numbers were strong. Datadog's revenue of $1.12 billion beat the roughly $1.08 billion consensus, and non-GAAP Earnings of $0.65 per share topped the $0.58 estimate. Non-GAAP Operating Income was $257 million, a 23% margin, while GAAP operating income was only about $5 million. GAAP Net Income came to $0.12 per diluted share, with stock-based compensation accounting for most of the gap between the two measures.

Customer growth also remained healthy. The number of customers generating $100,000 or more in annual Recurring Revenue rose 23% to about 4,720 from about 3,850 a year earlier. Operating Cash Flow was $316 million and free cash flow was $279 million, and the company ended the quarter with about $5.0 billion in cash and equivalents. Chief Executive Olivier Pomel described it as "a strong quarter" in the company's release.

Why the Guidance Disappointed

For the third quarter, Datadog guided to revenue of $1.135 billion to $1.145 billion, non-GAAP operating income of $260 million to $270 million and non-GAAP EPS of $0.63 to $0.65. The EPS range is flat to slightly below the second quarter's $0.65. For the full year, the company raised its outlook to revenue of $4.45 billion to $4.47 billion, non-GAAP operating income of $1.01 billion to $1.03 billion and non-GAAP EPS of $2.50 to $2.54.

Datadog has often beaten its own quarterly revenue guidance in the past, so the third-quarter range may prove cautious. Still, investors who had pushed the stock higher were looking for a stronger signal of acceleration. The free cash flow margin also slipped to about 25% from about 29% in the prior comparison, adding to concerns about margins. An earlier downgrade by Bernstein over the possibility of slower growth in core observability Demand also weighed on sentiment.

Insider Selling in Context

Li's Sep 11 sale was made under a Rule 10b5-1 trading plan adopted on June 12, 2026. Such plans let executives schedule sales in advance, which reduces the risk of trading on inside information, so the sale does not necessarily signal a view on the stock. Li still held about 250,446 shares directly after the transaction. Reports compiled from SEC filings show that other Datadog executives, including the chief technology officer, also sold shares in early September. Routine, preplanned insider sales are common at large technology companies whose executives receive much of their pay in stock.

Datadog's Platform and the AI Opportunity

Datadog sells a cloud-based platform that lets engineering teams monitor infrastructure, applications, logs and security in a single place. Its model is usage-based, so revenue grows as customers move more workloads to the cloud and send more data through the platform. That model has benefited from the build-out of AI applications, which generate large volumes of data that need monitoring. Many large customers use several Datadog products at once, spanning infrastructure monitoring, application performance monitoring, log management and security, and expanding spending within existing accounts has long been a central part of the company's growth.

The company is also expanding into AI tools of its own. At its DASH 2026 conference, it launched more than 100 capabilities, including autonomous Bits AI agents, AI Guard and Bits Agent Builder. It also acquired Adaptive ML and was named a Leader in the Gartner Magic Quadrant for Observability Platforms for the sixth consecutive year, according to the release.

Competition and Risks

Datadog competes with observability and security vendors such as Dynatrace (NYSE:DT), Elastic (NYSE:ESTC), Grafana Labs and Cisco's (NASDAQ:CSCO) Splunk, as well as with the native monitoring tools offered by Amazon Web Services (NASDAQ:AMZN), Microsoft Azure (NASDAQ:MSFT) and Google Cloud (NASDAQ:GOOGL). Open-source alternatives and customer efforts to cut monitoring costs can pressure pricing.

Key risks include slower cloud spending, customers optimizing their usage, and exposure to fast-growing AI-native companies whose spending can change quickly. Stock-based compensation keeps GAAP profits thin, and continued insider selling, even when preplanned, can weigh on sentiment. The stock's valuation also leaves limited room for guidance that only meets expectations.

The Metrics That Could Reverse the Slide

The next major test is Datadog's third-quarter 2026 report, which is expected in early November based on the company's usual calendar, although a date had not been confirmed in the materials reviewed. Investors will focus on whether revenue lands well above the $1.135 billion to $1.145 billion guidance, whether growth in large customers holds above 20%, and whether free cash flow margins stabilize.

Commentary on AI-driven usage, adoption of the Bits AI products announced at DASH and the company's first outlook for 2027 will also be important in determining whether the shares can regain the ground lost after the August report.
