MongoDB Shares Plunge 13.5% Despite Strong Earnings Beat Due to Atlas Cloud Growth Plateau

MongoDB shares tumbled 13.5% to close at $375.40, wiping out over $4 billion in market value, despite beating Wall Street's second-quarter revenue and profit estimates and raising its full-year guidance. Total revenue reached $771.8 million—up 30% year-over-year against expectations of $735 million—while adjusted earnings of $1.90 per share topped the $1.61 consensus.
The sharp sell-off was triggered by MongoDB’s Atlas cloud database platform, which grew 28.9% year-over-year. While beating the company's own guidance, the figure missed the roughly 30% buyside expectation, marking the fifth consecutive quarter Atlas growth has plateaued near that level. Major Wall Street firms including Barclays, Guggenheim, and Mizuho largely defended the company, maintaining positive ratings and raising price targets while viewing the drop as a valuation reset for high-multiple consumption software.
