MongoDB shares fell 18.5% on Monday after the MongoDB CEO quit. Chirantan “CJ” Desai left to take a senior role at Meta Platforms. He had run the database company for less than a year.
The company announced the change before the market opened on 28 September. Desai left with immediate effect. The board named former chief executive Dev Ittycheria as interim president and CEO.
The board has hired an executive search firm to find a permanent leader. Meanwhile, MongoDB reaffirmed the third-quarter and full-year guidance it gave on 1 September.
A short tenure at the top
Desai joined MongoDB on 10 November 2025. The company hired him from Cloudflare, where he was president of product and engineering. Before that, he was president and chief operating officer at ServiceNow.
His arrival marked the end of Ittycheria’s 11-year run. Over that time, Ittycheria grew annual revenue from about $35 million to more than $2.3 billion. He then stayed on the board as an adviser.
Desai brought more than 25 years of experience in enterprise software. At ServiceNow, he helped the company grow from $1.5 billion to over $10 billion in annualised revenue. The board hoped he could repeat that path.
Now Ittycheria returns to the job he handed over less than 11 months ago. Chair Tom Killalea said the business is strong. He added that there is no better person to lead it in the interim.
How much value the MongoDB CEO exit erased
The shares closed at $334.68, down from $410.44 on Friday, according to Nasdaq data. With about 80.6 million shares outstanding, the fall wiped roughly $6.1 billion off the company’s value.
It was the stock’s second-worst day of 2026. Only a 22.2% drop on 3 March was larger. The slide also came on top of a 13.5% fall on 2 September, the day after the company reported results.
That earlier drop came even though MongoDB raised its full-year outlook. The shares had nearly doubled from their April low before that report. Monday’s news added a leadership question on top.
Over the full year, the stock has been on a roller coaster. It ended 2025 at $419.69 and sank to $225.95 in April. It then rallied to $472.29 in August before this month’s two sharp drops.
The business itself is still growing
The timing is awkward because results were strong. In its second-quarter report, revenue rose 30% to $771.8 million. Desai called it the fastest growth in several years.
Atlas, the cloud database service, drove most of that gain. Atlas-related revenue rose 29% to $565.9 million, or about 73% of the total. Atlas customers passed 69,300, up from about 58,500 a year earlier.
Profitability improved as well. The adjusted operating margin rose to 24% from 15%. Free cash flow nearly doubled to $137.6 million, and the company held $2.4 billion in cash and investments.
On a GAAP basis, the company swung to an operating profit of $28.4 million from a loss a year earlier. Net income came to $40.9 million, or 50 cents a share. Customers paying at least $100,000 a year reached 2,999.
The guidance still stands for now. MongoDB expects $2.99 billion to $3.03 billion in revenue for fiscal 2027. For the third quarter, it forecasts $756 million to $761 million. It also expects adjusted earnings of $6.39 to $6.58 a share for the full year.
Those numbers now rest with a new leader. Still, Ittycheria knows the business well, having built most of its revenue base. That continuity may limit the disruption for customers and staff.
What investors will watch
The key question is strategy. Desai had pushed the company deeper into AI tools, such as vector search. He also launched a managed server that links coding agents to Atlas data. Investors will want to know whether that agenda survives a second MongoDB CEO change in a year.
MongoDB holds an investor day at Nasdaq on 29 September. The meeting now doubles as a first test for the returning leader. Any change in targets would also show up in its next quarterly filing.
More broadly, the move shows how fiercely big tech firms compete for AI talent. For software stocks, it is a reminder that a sudden MongoDB CEO exit can outweigh a strong quarter. Investors tracking AI adoption will watch who the board picks next.
