CJ Desai, MongoDB’s CEO, attributed the company’s strong Q3 2026 financial results primarily to the strong performance of its cloud platform, Atlas, which saw a 30% year-over-year increase in revenue.
Based on the company’s Q3 2026 performance, management upwardly revised fiscal 2026 revenue to $2.434 billion to $2.439 billion from the fiscal 2026 sales forecast of $2.25 billion to $2.29 billion that it provided in June. Similarly, the company expects a better performance at the bottom of the income statement. While management had originally forecasted adjusted EPS of $2.94 to $3.12, it now projects adjusted EPS of $4.76 to $4.80.
Is it too late to click the buy button on MongoDB stock?
While they have a higher price tag than they did this morning, MongoDB’s shares are reasonably valued. Priced at 11.8 times trailing sales — a discount to their five-year average sales multiple of 14.7 — MongoDB stock is trading at a discount to its historic sales valuation.
For investors seeking exposure to cloud computing, MongoDB is a valid option; however, those with a lower tolerance for risk may feel more comfortable with a cloud computing exchange-traded fund that includes MongoDB among its holdings.
