MongoDB shares drop 30% post-earnings on slower Atlas growth and cautious FY27 outlook despite strong Q4 results.

MongoDB's stock fell 30% after its earnings report showed a slowdown in Atlas growth and cautious revenue guidance for FY27, despite a 26.75% year-over-year revenue increase to $695.1 million in Q4 FY26 and improved operating margins. The company projects 16–18% revenue growth and a slower 22% growth in Atlas for the next fiscal year, tempering near-term expectations. However, the analyst maintains a 'buy' rating, citing attractive risk-reward and potential upside from MongoDB's strategic positioning in AI, which is not yet a significant revenue driver but may boost future growth.
