MongoDB — FQ1 FY2027 Earnings Preview

FQ1 FY2027 = Quarter ended April 30, 2026  ·  Reports Thursday, May 28, 2026 AMC (conference call 5:00 pm ET)  ·  Prepared May 21, 2026  ·  FYE Jan 31  ·  7 days out

MongoDB reports FQ1 FY2027 (quarter ended April 30, 2026) next Thursday, May 28 AMC. The setup is unusually constructive: Q4 FY26 print blew through every guide range (revenue $695M vs $664M high = $31M / +4.7% beat), Atlas growth re-accelerated to +29% YoY, total RPO doubled to $1.47B, and new CEO CJ Desai (first full quarter) delivered an FY27 outlook that calls for +16-18% revenue growth, +100bps margin expansion, and Atlas at +21-23%. The market has rewarded the print and outlook — stock sits at $329 (vs $213 12-month low). The Q1 print is now about confirmation that the new CEO regime can execute and that the Voyage AI / agentic AI thesis is monetizing as Atlas consumption expands.

Bull case: The story has structurally improved. Atlas is 72% of revenue and growing +29%, with consumption holding up across diverse customer cohorts. $100K+ ARR customers up to 2,799 (+17%); $1M+ customers at 402 (+26%). 44% of Atlas $100K+ customers now leverage 2+ platform features (vs 36% YoY) — "platform" attach is the real durable growth signal. Voyage AI (acquired Feb 2025) doubled vector-search customer count YoY; embedded models are the agentic-AI memory layer that competitors lack. RPO at $1.47B (+97% YoY) locked in by multi-year EA deals — visibility is materially better than at any prior point. FY27 revenue guide of +16-18% implies the consumption base is durable and Atlas can continue to outgrow. Above-Rule-of-40 performance in Q4 with 23% op margin proves the operating model scales.

Bear case: The Q4 beat was partly driven by multi-year EA deal duration (CFO Berry explicitly flagged "higher-than-expected multiyear EA deals" as a working-capital driver). FY27 non-Atlas guide of "low-to-mid single digit growth" implies the EA acceleration is being modeled to decelerate sharply. Atlas +21-23% FY27 guide vs Q4 actual +29% bakes in deceleration. New CEO transition risk remains — CJ Desai is one quarter in. Op margin guide of 19.5% implies sequential deceleration vs Q4 23% as investments ramp (Japan, US Federal, EA feature parity, marketing). Stock at $329 trades at ~14x EV/Sales on FY27 — a premium to hyperscaler database peers (Databricks private at lower multiple). AI native customer base remains "early" and not yet meaningful — the AI monetization narrative is still aspiration, not contribution.

What's at stake: Confirmation that (a) Q1 lands at or above the $664M / $1.19 high end of guide, (b) Atlas grows at or above +26% as guided, (c) the FY27 envelope is reaffirmed (especially the non-Atlas low-to-mid single-digit growth that anchors the back half), (d) new customer adds / $100K+ cohort continues the L4Q trajectory, and (e) management quantifies AI / Voyage contribution. A clean print likely takes the stock back toward $370 (52-wk high); a Q1 miss or Atlas decel below +25% likely re-tests the $280-$300 zone.

Guidance set on Q4 FY26 earnings call, March 3, 2026. Consensus sits at the high end of Q1 EPS and revenue guides — small beats baked in.

Revenue growth accelerated from +12.8% in Q2 FY25 to +26.7% in Q4 FY26 — exiting FY26 at a 14pt higher rate. Atlas customer count grew +34% YoY (47.7K → 63.9K). Op margin doubled from 11% to 23% over 7 quarters. FCF inflection from -$4M Q2 FY25 to +$177M Q4 FY26 reflects operating leverage and EA cash collection. Every cell links to its Daloopa source page.

What happened in FY26: Atlas growth decelerated through Q4 FY25 to +24% (post-COVID consumption normalization), then re-accelerated quarter-by-quarter through FY26: +26 → +29 → +30 → +29%. Atlas now sits at 72% of total revenue (up from 70% YoY) and Q4 FY26 print was the strongest in 7 quarters.

Why it re-accelerated: Three drivers per management commentary — (1) consumption stabilization across the customer base, including the AI native cohort that had been a headwind; (2) platform attach — 44% of Atlas $100K+ customers now use 2+ features (vector search, Atlas Search, Charts, Stream Processing), up from 36% YoY; (3) upmarket motion — $1M+ ARR customers up +26% YoY to 402, with this cohort growing ARR faster than the customer count itself.

Voyage AI (acquired February 2025 for ~$220M) is the strategic acceleration vector: vector search customer count nearly doubled YoY, embedded model usage doubled since the acquisition closed. Voyage gives MongoDB the proprietary embedding-model layer that competitors lack — relevant for agentic AI memory workloads.

The Q1 FY27 setup: Management guided Atlas to ~+26% in Q1 (vs Q4 +29%) and +21-23% for the full year. The Q1 guide implies some moderation from the Q4 peak but remains well above the FY26 average. The +21-23% FY27 Atlas guide is conservative given Q4 exit-rate; investors will look for management to suggest upside. Any Atlas print >+27% would be received very positively.

Watch list:

• Net new Atlas customer adds — Q4 added 3,100 (53.1K → 63.9K = ~10K added in FY26)
• Atlas as % of total revenue — sustained move above 73% confirms mix shift
• $1M+ ARR customer additions — 402 today; pace of additions = upmarket health
• Platform attach rate — 44% today; trend toward 50% = ARR durability
• Voyage / vector search disclosure — any quantified ARR contribution
• AI native cohort commentary — when does this move from "not meaningful" to material?

The cleanest read on MDB's FY27 setup is that non-Atlas (EA/Community Server) revenue is being modeled to decelerate sharply. Berry's commentary: "low to mid-single-digit growth in fiscal '27" for non-Atlas. Compare to FY26 actual where non-Atlas grew low-double-digits driven by multi-year EA deal duration impact.

What is multi-year EA duration? When a customer signs a 3-year EA contract, MongoDB recognizes a larger upfront license revenue chunk than a 1-year contract (term licenses). In FY26, MDB benefited from "higher-than-expected multiyear EA deals" — which Berry flagged as a working-capital tailwind for cash collection. This created a YoY tailwind in non-Atlas revenue that won't repeat at the same magnitude in FY27 (the comp is now harder).

What it means for the print: Q4 FY26 revenue beat was driven partly by EA deal closures. Q1 FY27 has a slightly tougher non-Atlas comp. If non-Atlas grows mid-single-digit in Q1 as guided, the total revenue beat will need to come from Atlas execution (Atlas +27%+ in Q1 = clean beat). If non-Atlas surprises with another multi-year EA cluster, that is upside; if non-Atlas declines, it would indicate the FY26 strength was deal-timing rather than secular demand.

RPO is the key signal: RPO grew from $748M end-FY25 to $1.47B end-FY26 = +97% YoY. This is the locked-in backlog from multi-year EA deals. Continued RPO growth in Q1 confirms durable deal pipeline; deceleration to flat or down RPO would be a meaningful bear datapoint.

Key takeaway: MDB has crushed both top-line and EPS consensus every quarter for the trailing 8. Revenue beat magnitudes accelerated through FY26 (+4% Q1 → +6.7% Q2 → +6.3% Q3 → +10.5% Q4) reflecting both Atlas consumption acceleration and multi-year EA deal closures. EPS beats have averaged +42% L4Q — driven by operating margin upside on revenue strength. A repeat of L4Q average revenue beat (+6.9%) on $664M consensus implies a print of ~$710M. A repeat of EPS beat magnitude (+43%) on $1.18 consensus implies ~$1.69. Both would be record-breaking; even a fraction of historical beat magnitude maintains the streak comfortably.

Bull Catalysts

Bear Risks

1. Q1 revenue vs $659-$664M guide: Street is at ~$664M (high end). $670M+ is a clean beat; below $664M would be first revenue miss in 8 quarters.

2. Q1 non-GAAP EPS vs $1.15-$1.19 guide: Street is at $1.18 — near the high end. Margin upside has driven historical EPS beats — repeat would put EPS above $1.25.

3. Atlas revenue growth YoY: Guided ~+26%. Q4 FY26 was +29%. Anything below +25% breaks the acceleration story; +28%+ is bullish reaffirmation.

4. Non-Atlas revenue trajectory: Guided low-mid single digit growth in Q1. Watch for sequential context — is the EA pull-forward fully digested?

5. FY27 guidance reaffirmation: $2.86-$2.90B revenue, $5.75-$5.93 EPS, 19.5% op margin, +21-23% Atlas. Any nudge to low end = bearish; reaffirmation or raise = bullish.

6. Atlas customer count net adds: Q4 added ~3,100 (60.8K → 63.9K). Q1 trajectory tells consumption signup velocity.

7. $100K+ customer cohort growth: 2,799 customers / +17% YoY in Q4. Watch for continued acceleration toward 2,900-2,950.

8. $1M+ ARR customer count: 402 customers / +26% YoY in Q4. The upmarket cohort drives ARR durability.

9. Platform attach rate (multi-feature customers): 44% of $100K+ Atlas customers in Q4. Trajectory toward 50% = real platform thesis.

10. RPO and current RPO disclosure: Total RPO $1.47B at end-FY26 (+97%). Continued growth confirms multi-year deal pipeline.

11. Voyage AI / vector search commentary: Vector customer count, embedded model usage, any quantified ARR contribution. First quantification = positive.

12. Op margin vs ~16.5% Q1 guide: Investment cycle in Japan / Federal / EA feature parity. Margin upside = revenue overdelivery.

13. New CEO Desai's commentary tone: First Q with him at the helm post the Q4 full quarter. Looking for substance and confidence in customer commentary.

14. FCF / OCF cadence: Q4 FCF was $177M. FY27 guide commits 100% of FCF to buyback + RSU tax. Cadence implies $300-400M Q1 FCF potential.

15. Macro / tariff framing: MDB has been silent on macro. Any introduction of caution language would be first time.
