Shares of MongoDB (NASDAQ: MDB) slumped out of the gate on Wednesday, plunging as much as 14.6%. As of 11:02 a.m. ET, the stock was still down 10.8%.

The catalyst that drove the database-as-a-service (DBaaS) provider lower was its quarterly financial report. While the results were better than expected, investors wanted more.

Too much is never enough

For its fiscal 2027 second quarter (ended July 31), MongoDB delivered revenue of $772 million, up 30% year over year, showing that its strategy to tap into the booming demand for artificial intelligence (AI) is paying off. As a result, the company delivered adjusted earnings per share (EPS) of $1.90, which rose 90%.

For context, analysts' consensus estimates were looking for revenue of $734 million and adjusted EPS of $1.61, so MongoDB surpassed both benchmarks with room to spare.

MongoDB continued to attract new users, adding 2,900 net new customers to the company's database-as-a-service solution -- Atlas -- bringing the total to 70,600, up 18% year over year.

The company also continues to generate plenty of cash, with operating cash flow of $141.9 million and free cash flow of $137.6 million, both up 97%.

The AI wildcard

Over the past few years, MongoDB has pivoted to adapt its offerings to focus on the accelerating adoption of AI. That strategy is paying off, as customers deploying AI on its Atlas database now account for 30% of the company's annual recurring revenue. Customers are using the secure Atlas environment to build AI applications, while also allowing AI agents to tap into complex data sets.

As a result of the company's robust performance, management increased its full-year guidance. MongoDB is now forecasting revenue of $3 billion and adjusted EPS of $6.49, or growth of 22% and 31%, respectively, at the midpoint of its guidance.

MongoDB stock isn't cheap, selling for 63 times forward earnings and 53 times next year's expected earnings. Investors found it hard to justify a premium of that magnitude with low-double-digit growth -- which helps explain today's sell-off.
