Datadog 10-Qquarter ended 2026-09-30

Executive Summary

Datadog sells cloud-monitoring and security software to businesses, earning subscription revenue tied largely to usage. It is expanding an AI-powered platform spanning more than 20 products, aiming to grow as customers add workloads and adopt more tools. Q3 revenue grew 35%, and operating income reached $74.7M as spending grew more slowly than sales. Broader product adoption supports that strategy, but declining usage from the largest customer shows why investors should distinguish durable customer expansion from volatile AI-related demand.

What's Happening in the Business

Existing customers supplied ≈70% of revenue growth, with new customers contributing the rest. The customer base reached ≈33,500, up 4.7%, while customers generating at least $0.100M in annual recurring revenue increased 20% to ≈4,860. Those larger customers now represent 91% of annual recurring revenue, making deeper enterprise relationships more important than customer-count growth alone.

Cross-selling is gaining traction: 41% of customers used at least six products, vs 31% a year earlier. Trailing 12-month dollar-based net retention—spending by existing customers relative to a year earlier—was in the low-120% range, primarily reflecting higher usage.

AI-native customers contributed a high-single-digit percentage-point share of company revenue growth. However, the largest customer reduced usage during Q3, and management cautioned that this could moderate growth. The quarter’s growth slightly exceeded the nine-month pace, but that customer’s behavior introduces uncertainty into the outlook.

Datadog continues investing in engineering, infrastructure, sales and international expansion, particularly Europe and Asia-Pacific. R&D rose 22% to $492M in Q3, slower than revenue, helping operating profitability improve without a retreat from product investment.

Key Financial Highlights

• Gross margin: Q3 was unchanged at 80%; nine-month margin declined to 79% from 80%. Additional cloud-hosting and software costs contributed $52.1M to Q3 cost growth, showing the infrastructure expense accompanying higher usage.
• Stock-based compensation: Operating expense was $237M in Q3, +18%, and $654M over nine months, +20%. This noncash expense helps explain the cash-flow/earnings gap but carries dilution: outstanding shares rose 2.4% from year-end to 361M.
• Liquidity: Cash and marketable securities totaled $5.23B against convertible notes with $1.00B principal due in 2029. The liquidity cushion supports continued investment without immediate refinancing pressure.
• Contract visibility and commitments: Remaining performance obligations reached $3.85B, +11% from year-end, with substantially all expected to become revenue within 24 months; usage-based drawdown timing remains uncertain. Uncommenced leases add $321M of payments—equivalent to 34% of nine-month operating cash flow, although payable over future lease terms.

Risk Assessment

• Customer concentration and usage: The largest customer’s usage reduction could outweigh expansion elsewhere, while short subscription terms allow customers to optimize spending or decline renewal.
• Security and service reliability: The 2025 unauthorized access to source-code repositories illustrates trust risk, while reliance on third-party hosting exposes multiple products to outages, capacity constraints and costly migrations.
• Product execution and competition: Maintaining more than 1,000 integrations while expanding AI and security products requires sustained investment; cloud providers, open-source tools and customer-built alternatives could limit adoption or pricing.
• Dilution and control: Equity compensation and possible convertible-note share settlement can dilute investors, while Class B holders’ ≈41% voting power limits Class A shareholders’ influence.

What to Watch

• Largest-customer usage: It declined during Q3 despite strong AI-native cohort growth. Stabilization would support more durable expansion; further reductions could moderate company growth.
• Multi-product enterprise adoption: Six-product adoption reached 41%. Further adoption and growth in large customers would validate the broader platform strategy; weaker retention would challenge it.
• Sustainable operating profitability: Q3 improved much more than the nine-month result. Subsequent filings should show whether revenue continues outgrowing personnel and hosting costs without weakening customer expansion.
