MongoDB Q2 Earnings Raise Outlook, Shares Slip on Atlas

MongoDB Q2 earnings showed stronger revenue and a raised full-year outlook in a press release and Form 8-K on Sept. 1, 2026, but the stock declined after investors focused on a stall in Atlas growth.

Q2 Results and Investor Reaction

For the quarter ended July 31, 2026, MongoDB, Inc. (NASDAQ: MDB) reported fiscal second-quarter revenue of $771.8 million, up 30% year over year. Atlas-related revenue totaled $565.9 million, while Enterprise Advanced and other revenue reached $181.2 million. Subscription revenue was $747.1 million, and services revenue was $24.6 million. The company posted GAAP operating income of $28.4 million, reversing a $65.3 million loss a year earlier. Net income was $40.9 million, or $0.50 diluted earnings per share (EPS), and non-GAAP operating income was $185.9 million.

MongoDB raised its full-year fiscal 2027 revenue guidance to a range of $2.99 billion to $3.03 billion and increased its non-GAAP operating margin outlook, expecting a 250-basis-point expansion. For the third quarter, it projected revenue between $756 million and $761 million and non-GAAP EPS of $1.57 to $1.61.

Shares fell after investors focused on Atlas growth appearing to flatten. The company reported Atlas revenue grew about 29% year over year for the fifth consecutive quarter, a detail that shaped investor reaction despite the overall revenue gains. The filings did not attribute the share decline to any specific cause.

Management linked the raised outlook to continued enterprise demand, Atlas consumption growth, and early adoption of artificial intelligence (AI) workloads. The customer base reached 70,600, driven by a record 2,900 net new customers in the quarter, underscoring demand even as investors concentrated on the pace of Atlas expansion.
