Financial Trends -- 8/10

Revenue re-accelerating at scale. Growth bottomed at ~13% in FQ2 FY25 and re-accelerated to +27% by FQ4 FY26, driven by Atlas strength and large multiyear EA deals. FY27 consensus estimates reflect management guidance of 16-18% growth, which is conservative given the beat-and-raise pattern (FY26 actual beat initial guide by $190M).

Atlas re-accelerated from +24% to +30%. Atlas (72-75% of revenue) re-accelerated from a trough of +24% in FQ4 FY25 to +30% in FQ3 FY26, driven by improving workload cohorts, upmarket strength, and broad-based consumption growth. Management attributed this to core pre-AI demand, with AI contribution described as "still early."

Massive operating leverage. Non-GAAP operating margin expanded from 7% (FQ1 FY25) to 23% (FQ4 FY26) -- a 16-point improvement in 8 quarters. GAAP margins improved from -22% to near breakeven. The gap between GAAP and non-GAAP is almost entirely SBC ($574M in FY26), which is the key concern. Management targets 100-200bps average annual margin expansion per their Investor Day framework.

FCF inflection -- $115M to $493M (+330% YoY). FCF margin expanded from 5.7% (FY25) to 20.0% (FY26). FCF conversion exceeded 100% of non-GAAP net income. This was driven by strong operating profit growth and improving working capital. Management has committed 100% of FCF to share buybacks via the $1B repurchase program.

Healthy customer expansion across all cohorts. Total customers grew +20% YoY (54,500 to 65,200), accelerating from +14% a year ago. $100K+ customers grew +17% YoY. $1M+ ARR customers grew +26% YoY (320 to 402), confirming upmarket traction. Net ARR expansion improved from a 118% trough in FQ4 FY25 to 121% in FQ4 FY26.

SBC is $574M (23% of revenue) -- the GAAP/non-GAAP bridge is almost entirely stock comp. While SBC as a percentage of revenue is declining (from 28% to 22%), the absolute level keeps GAAP net income negative (-$71M in FY26). Gross margins compressed ~200-300bps from FY24 peaks as Atlas (slightly lower margin) grows as a share of the mix. This is structural but manageable -- Atlas margins are improving YoY.

Final Score: 8.0 / 10. MongoDB is a high-quality growth compounder with improving unit economics. Revenue re-accelerated to +27% at $2.5B scale, non-GAAP margins expanded from 7% to 23%, and FCF inflected from $115M to $493M. The score is penalized modestly for the GAAP/SBC gap ($574M, 23% of revenue) and structural gross margin compression from Atlas mix shift. All customer metrics are improving and the beat-and-raise management pattern suggests FY27 consensus estimates (16-18% growth) are beatable.
