DDOG — Q4 FY25 Earnings Review (Atlas)

Date: 2026-04-03 Quarter: Q4 FY25 (Dec-2025) Earnings Date: 2026-02-10 Market cap: $41.9B | EV/TTM Rev: 11.2x | Revenue growth: 29.2% YoY

Verdict

Datadog delivered its best quarter in two years — $953M revenue at 29.2% YoY growth, accelerating for the fourth consecutive quarter, with record bookings of $1.63B (+37% YoY) and record FCF of $291M. The non-AI-native re-acceleration from 20% to 23% in Q4 is the most important signal in the report: this is not a one-dimensional AI story. FY26 guidance of 4.06B4.10B looks deliberately conservative given the structural 4.3% beat pattern and record bookings pipeline. The stock is mispriced at 11.2x EV/TTM Revenue with accelerating 29% growth.

Conviction: 4/5. Q1 FY26 is the catalyst — a 4%+ beat would imply ~31% YoY growth, the first 30%+ quarter since Q1 FY23. Not 5/5 because of largest-customer concentration opacity and SBC at 22% of revenue growing faster than the topline.

Qualification Gate

Criterion Threshold DDOG Q4 FY25 Verdict
Revenue YoY growth >30% (>40% preferred) 29.2% (accelerating, 4th straight quarter) Borderline PASS — trajectory points to 30%+ in Q1 FY26
Gross margin >60% (>70% preferred) 80.4% GAAP / 81.4% Non-GAAP PASS
Revenue per quarter >$50M $953.2M PASS
Data availability 4+ quarters in DB 16 quarters PASS
Share dilution <10% annual 1.3% (360.9M -> 365.5M) PASS
GAAP profitability trajectory Improving or positive FY25 GAAP net income $108M (+120% YoY) PASS

Gate result: PASS. Revenue at 29.2% is 0.8pp below the 30% hard threshold but every leading indicator — bookings, customer adds, NRR, AI adoption — points to imminent crossover. Applying the structural beat pattern to Q1 FY26 guide yields ~31% YoY.

Six-Factor Score

Factor Rating Detail
Growth Strong 29.2% YoY Q4 FY25, accelerating 4 consecutive quarters from 24.6% trough. FY25 $3.43B (+28% YoY). FY26 guide $4.08B midpoint (19%), but structural beats suggest 24-26% actual.
Trajectory Accelerating YoY: 24.6% -> 28.1% -> 28.4% -> 29.2%. Bookings +37% outpacing revenue by 8pp — classic bullish leading divergence. $1M+ customer growth at 31% YoY, also ahead of revenue.
Margins High GAAP GM 80.4%, Non-GAAP GM 81.4%, Non-GAAP op margin 24.1%, FCF margin 30.5% (Q4). Rule of 40: 60 (Q4 — 29.2% + 30.5%). TTM FCF $915M at 27% margin.
Dominance Dominant #1 observability platform. 120% NRR. 84% multi-product adoption. 48% Fortune 500 as customers. 14/20 top AI companies. Forrester Wave Leader. No layoffs in company history. S&P 500 member.
Valuation Fair EV/TTM Rev 11.2x at 29% growth (0.38x growth-adjusted). EV/TTM FCF 42x. Non-GAAP P/E 58x. Below 2-year average (~15-16x revenue). Cheaper than CRWD (18.8x, 22% growth).
Special Present (1) Bookings +37% YoY = strongest forward indicator. (2) Structural 4.3% beat pattern on 8 consecutive quarters. (3) FY26 guide de-risks largest customer — any stabilization is free upside. (4) Agentic AI tailwind (MCP server 11x QoQ, AI SRE 2,000+ customers in month 1).

Prior Beliefs / Updated Beliefs

Context: This is Atlas's first earnings-review for DDOG. "Prior Beliefs" are constructed from Q3 FY25 results, Q4 FY25 guidance (912M916M midpoint), and the established beat pattern.

Prior Beliefs (Pre-Q4 FY25)

  1. Revenue: Expected ~$950-955M based on structural 4.3% beat on $914M guide midpoint. Growth of ~28-29% YoY (continuing Q3's 28.4% trajectory).
  2. Gross margin: Expected ~80-81% GAAP — stable trend.
  3. Non-GAAP operating margin: Expected 23-24%, consistent with Q3's 23%.
  4. FCF: Expected $240-260M, seasonal Q4 strength.
  5. Customer growth: Expected $100K+ at ~4,100-4,200 (continued 15-17% YoY cadence). $1M+ at ~570-585 (~28-30% YoY cadence).
  6. NRR: Expected 118-120%, with mild concern about deflationary pressure.
  7. FY26 guidance: Expected ~3.9B4.0B (17-19% YoY) given conservative management posture.

Updated Beliefs

Metric Expected Actual Verdict
Revenue $950-955M $953.2M (+29.2% YoY) In-line — structural beat intact at 4.3%
Gross margin [GAAP] ~80-81% 80.4% In-line
Non-GAAP op margin 23-24% 24.1% In-line, top of range
FCF $240-260M $291M (30.5%) Beat — record, well above expectations
$100K+ customers 4,100-4,200 4,310 (+19% YoY) Beat — net adds accelerating (250 vs. 210 in Q3)
$1M+ customers 570-585 603 (+31% YoY) Beat — 31% growth, fastest rate in available history
NRR 118-120% ~120% In-line — stable, refuting near-term deflationary thesis
FY26 guide $3.9-4.0B 4.06B4.10B ($4.08B mid) Beat — higher than expected
Bookings No expectation (new disclosure) $1.63B (+37% YoY, record) Positive surprise — first disclosure, 8pp ahead of revenue
Non-AI-native growth 20-22% (stable) 23% (accel from 20%) Positive surprise — broad-based re-acceleration confirmed
AI metrics Growth expected 5,500+ AI customers, 650 AI-native, 19 at $1M+, AI SRE 2,000+ in 1 month Positive surprise — product velocity faster than expected

Delta Assessment

Three things surprised me:

  1. Bookings disclosure and magnitude. 1.63Bat + 3710M TCV and 2 deals >$100M TCV show enterprise deal size expansion. This is a durable bookings backlog that de-risks H1 FY26 revenue.

  2. Non-AI-native re-acceleration. Growth in the non-AI customer base jumped from 20% to 23% in one quarter. Management raised this unprompted in prepared remarks — they wanted the market to see it. This rebuts the narrative that DDOG is a one-trick AI pony. The base business is genuinely re-accelerating, likely driven by cloud migration resumption and multi-product expansion within existing accounts.

  3. Customer cohort acceleration. $1M+ customers grew 31% YoY — accelerating sharply from 17% in Q4 FY24. $100K+ net adds hit 250, the highest quarterly add in the dataset. Both cohorts are growing faster than revenue, which means upmarket traction is pulling the average deal size higher. This is the opposite of what a deflationary-architecture narrative predicts.

What did NOT surprise me: Revenue was dead-in-line with the beat pattern. Margins were stable. NRR held. These are signs of consistency, not inertia — the model is predictable and compounding.

Leading Indicators

Bullish Divergence — Confirmed and Widening

Indicator Value vs. Revenue (29.2%) Direction Quarters Sustained
Bookings +37% YoY ($1.63B record) +7.8pp ahead New disclosure — first data point 1 (new)
$1M+ ARR customers +31% YoY (603) +1.8pp ahead Accelerating (was +17% in Q4 FY24) 4+ quarters of acceleration
$100K+ ARR customer net adds 250/quarter Accelerating (210 in Q3, 120 in Q4 FY24) Accelerating 3 quarters
NRR ~120% Stable Stable — refutes deflationary thesis At least 1 (first disclosure)
AI SRE agent adoption 2,000+ in month 1 N/A (new product) New product signal 1 (new)
MCP server tool calls 11x QoQ N/A (new product) Parabolic early adoption 1 (new)

Assessment: Bookings growing 37% vs. revenue 29% is an 8pp gap — a classic leading indicator of sustained revenue acceleration or at minimum revenue growth holding in the high-20s for the next 2-3 quarters.

No Bearish Divergence Detected

Nothing in the leading indicators suggests deceleration. The non-AI-native growth re-acceleration from 20% to 23% is especially important — the base business is accelerating independently of the AI narrative.

Scuttlebutt Findings

Scuttlebutt was conducted on 2026-04-02 (see stages/scuttlebutt/DDOG/2026-04-02.md for full sourcing).

Valuation Context

Metric Current ~1Y Ago (est.) Peer Median (est.) Assessment
EV/TTM Revenue 11.2x ~16x ~8-10x (DT/observability) Fair — premium to point observability, discount to historical
EV/TTM Gross Profit 14.0x ~20x ~12-14x Fair
EV/TTM FCF 42.0x ~60-70x ~35-45x Fair
P/E Non-GAAP (TTM) 58x ~70-80x ~40-50x Slightly rich — improving as earnings grow
Market cap $41.9B ~$45-50B -- Down ~15% from 1Y ago despite acceleration

Growth-adjusted: EV/Rev / Growth% = 0.38. Rule of 40 (Q4) = 60. PEG = 2.0. Stock at lowest multiple in 2+ years while growth at highest in 2 years. Market pricing the 19% FY26 guide, not the ~25% likely actual.

Platform & Secular Position

Secular tailwinds: Cloud migration (48% Fortune 500 at <$500K median — expansion runway), AI/agentic computing (5,500+ AI customers, MCP server 11x QoQ), security convergence (Cloud SIEM, Bits AI Security).

Platform assessment: True platform. Three pillars each >$1B ARR. 20+ products. 84% multi-product. 800+ integrations, OTel, MCP server.

TAM: Observability ~2.9B(2025)−> 6.9B (2031). Realistic TAM $15-20B. Penetration ~15-20%.

Key Risks

  1. Largest customer concentration. One account influencing 3-4pp of full-year growth. CFO modeled FY26 around its unpredictability.
  2. SBC growth outpacing revenue. $751M (22% of revenue), growing 32% YoY vs. 28% revenue growth. GAAP op margin -1.3% FY25.
  3. Pricing friction. Host-based HWM billing, custom metrics surcharges, dual log billing. Opens door for Grafana/SigNoz.
  4. AWS native tools. Goldman flagged as most dangerous competitive vector. Good enough and cheaper with zero integration friction.
  5. FY26 guidance deceleration optics. 19% midpoint guide changes the growth narrative on the surface.

Key Catalysts

  1. Q1 FY26 earnings (May 2026). A 4%+ beat on 956M−> 997M -> ~31% YoY. Re-rating catalyst.
  2. AI monetization crystallization. Quantified AI-specific ARR disclosure would crystallize the narrative.
  3. NRR stability through H1 FY26. Decisive metric for both Goldman bear and Morgan Stanley bull.
  4. Largest customer stabilization. FY26 guide zeros out upside — any positive surprise is free.
  5. Bookings conversion. $1.63B record bookings (+37%) should convert over next 2-3 quarters.
