MongoDB Q2 Fiscal 2027 Earnings: 30% Revenue Growth Drives Margin Expansion

MongoDB (NASDAQ: MDB) reported fiscal Q2 2027 revenue of $771.8 million, up 30% year over year, and GAAP diluted EPS of $0.50, compared with a $0.58 loss a year earlier. The central development was operating leverage: MongoDB reached GAAP operating profitability while free cash flow rose to $137.6 million from $69.9 million. The results cover the quarter ended July 31, 2026, and were released on September 1, 2026.

Core Financial Results

Subscription revenue increased 31% to $747.1 million, while services revenue rose 29% to $24.6 million. Management described the overall 30% revenue increase as MongoDB’s highest growth rate in several years.

Profitability improved because revenue grew considerably faster than costs. Total cost of revenue increased about 18%, and operating expenses rose about 12%, compared with 30% revenue growth. The following figures are in U.S. dollars, with amounts in millions except per-share data.

This was MongoDB’s third consecutive quarter of GAAP EPS profitability. The large difference between GAAP and non-GAAP results remains important, however, because the non-GAAP calculation excludes substantial stock-based compensation and related expenses.

Business and Segment Performance

Growth was distributed across both of MongoDB’s primary subscription categories. Atlas remained the larger business, but Enterprise Advanced and other revenue grew at the faster rate during the quarter.

Management attributed the performance to core enterprise workloads and early momentum from AI use cases across both Atlas and Enterprise Advanced. During the quarter, MongoDB also made Search and Vector Search generally available in Enterprise Advanced and introduced additional AI retrieval and agent-connectivity capabilities for Atlas. The company did not quantify the revenue contribution from AI use cases.

Growth was also geographically broad. Revenue increased approximately 31% in the Americas, 31% in EMEA, and 26% in Asia Pacific.

MongoDB ended the quarter with more than 70,600 customers, up approximately 18% from more than 59,900 a year earlier. Atlas customers increased to more than 69,300 from more than 58,500, while customers generating at least $100,000 in annualized recurring revenue rose about 17% to 2,999.

Remaining performance obligations reached $1.52 billion, up 91%, while current RPO increased 73% to $797.3 million. These figures indicate substantial growth in contracted commitments, although RPO includes items with different delivery and payment timelines.

Profitability, Cash Flow, and the Balance Sheet

Gross margin expansion and slower operating-expense growth produced the quarter’s operating leverage. Sales and marketing expense increased only about 4%, while research and development rose about 18% and general and administrative expense increased about 25%. In aggregate, operating expenses grew well below revenue.

Stock-based compensation remained a major part of the GAAP-to-non-GAAP difference. MongoDB recorded $148.9 million of stock-based compensation expense in its cash flow statement, while the non-GAAP operating-income reconciliation included $153.4 million of expenses associated with stock-based compensation and related items.

Operating cash flow exceeded GAAP net income partly because stock-based compensation is a noncash expense. That benefit was partially offset by a $69.3 million use of cash from accounts receivable during the quarter. After $2.5 million of capital expenditures and $1.8 million of finance lease principal payments, free cash flow was $137.6 million.

MongoDB finished the quarter with $2.4 billion in cash, cash equivalents, short-term investments, and restricted cash. The company repurchased approximately $100.0 million of common stock during the quarter and $200.3 million during the first six months of fiscal 2027.

Fiscal 2027 Guidance

MongoDB raised its full-year fiscal 2027 guidance and said the increase for the second half was mainly attributable to Atlas. The release did not provide the previous numerical ranges, so the size of the revision cannot be calculated from the supplied information.

The latest guidance includes the following ranges:

The Q3 outlook calls for a GAAP operating loss despite substantial expected non-GAAP operating income. The company’s reconciliation identifies $162.7 million of expected stock-based compensation-related expenses as the largest adjustment between those measures.

Risks Investors Need to Monitor

• Dependence on Atlas performance: Management said the full-year guidance increase for the second half was mainly due to Atlas. Changes in customer usage, renewals, or expansion could therefore affect the revised outlook.
• Persistent GAAP and non-GAAP divergence: MongoDB achieved GAAP operating profitability in Q2, but its Q3 guidance returns to a GAAP operating loss. Stock-based compensation remains the principal reason reported and adjusted profitability differ materially.
• Execution on AI investments: Management cited early momentum from AI use cases and launched several related products, but it did not quantify AI revenue. MongoDB also acknowledged that the AI data-infrastructure market could develop differently than expected or favor competing architectures.
• RPO conversion timing: RPO grew much faster than quarterly revenue, but it includes multi-year commitments and unfulfilled orders. Its growth should not be interpreted as an equivalent near-term revenue increase.

Summary

MongoDB’s fiscal Q2 2027 results combined 30% revenue growth with wider margins, GAAP operating profitability, and nearly doubled free cash flow. Atlas and Enterprise Advanced both contributed, while revenue growth outpaced cost and operating-expense increases. The main issues to watch are Atlas execution behind the raised full-year outlook, the expected return to a Q3 GAAP operating loss, and whether early AI momentum develops into a measurable source of durable growth.
