MongoDB Stock Plunges on Weak Guidance, Despite Q4 Earnings, Revenue Beat

MongoDB shares plunged 23.7% following its fourth quarter fiscal 2026 earnings report, as investors reacted negatively to the company’s first quarter guidance despite beating current quarter expectations.

The database software company reported adjusted earnings per share of $1.65 for the fourth quarter ended January 31, 2026, surpassing the analyst consensus of $1.48 by $0.17. Revenue reached $695.1 million, exceeding the $670.06 million estimate and representing a 27% increase YoY. Atlas-related revenue climbed 29% YoY to $502.6 million.

However, MongoDB’s guidance for the first quarter of fiscal 2027 disappointed investors. The company projected adjusted EPS of $1.15 to $1.19, with a midpoint of $1.17 falling short of the $1.21 consensus. First quarter revenue guidance of $659 million to $664 million, with a midpoint of $661.5 million, came in slightly below the $662.5 million analyst estimate.

For fiscal 2027, MongoDB forecasts adjusted EPS of $5.75 to $5.93, with a midpoint of $5.84 exceeding the $5.70 consensus. Full-year revenue guidance of $2.86 billion to $2.90 billion, with a midpoint of $2.88 billion, came in just below the $2.9 billion estimate.

"We delivered strong fourth quarter results driven by our continued go-to-market execution and the broad-based demand we are seeing across our product lines," said CJ Desai, President and Chief Executive Officer of MongoDB. "At the same time, we significantly outperformed on operating margin, achieving a rule of 40 performance."

MongoDB added 2,700 customers during the quarter, bringing its total customer count to over 65,200 as of January 31, 2026. The company reported 2,799 customers generating over $100,000 in annualized recurring revenue.
