MongoDB upgraded to Outperform from Neutral at Mizuho

Mizuho analyst Siti Panigrahi upgraded MongoDB (MDB) to Outperform from Neutral with a price target of $325, up from $290. The firm sees a “compelling” share setup post the company’s fiscal Q4 report. MongoDB’s growth profile “has inflected meaningfully” with fiscal 2026 net customer additions up 60% year-over-year, net revenue retention improving from 118% to 121%, and headcount growing just 1% against 23% revenue growth, which signal the business is “entering a new phase of efficient, durable growth,” the analyst tells investors in a research note. Mizuho also sees AI as a “structural tailwind” for MongoDB, with vibe coding expanding application creation and AI-enabled apps requiring more database workloads per application. It views the company’s fiscal 2027 outlook as conservative.
