MongoDB's shares fell more than 20% after the company issued guidance that fell short of analysts’ expectations. The company reported Q4 fiscal 2026 revenue of about $695.1 million, up 27% year over year, and non‑GAAP earnings of $1.65 a share, both ahead of Wall Street estimates. Full‑year revenue reached roughly $2.46 billion, also up in the mid‑20% range, while the Atlas cloud database business grew about 29% year after year. However, despite these strong results, the stock price fell. CEO CJ Desai stated that the company sees "broad‑based demand" across its products and plans to deliver innovations over the coming years. He also noted that AI should be a tailwind for MongoDB as many customers are using its database as the foundation for new AI‑driven applications.
