Michael J. Berry, chief financial officer of MongoDB (MDB), has filed 81 Form 4 transactions across four companies. The pattern is one-sided: zero open-market purchases and roughly $11.8 million in total sales. His recent activity, all in MDB, shows a cluster of 19 sales on June 16, 2026, ranging from $1,091 to $400,408, with most values between $30,000 and $170,000. Those trades sum to over $1.7 million for that single day. A smaller sale of $6,910 occurred the prior day, June 15.
The June 16 sales are the dominant recent signal. They are open-market sales, code S, and they follow a pattern of routine disposal rather than a single block exit. Berry also had shares withheld to cover tax obligations on October 1, 2026 ($727,200) and July 1, 2026 ($2.38 million), both code F transactions that are automatic and not discretionary. He received a grant on October 12, 2026 (code A, value $0) and made a gift on July 8, 2026 (code G, value $0). There is no purchase activity in the recent window, and the total buy value across all his filings is zero.
The mix of codes matters. The S sales are the only trades where Berry chose to sell into the market. The F transactions are mechanical, tied to tax withholding on vested equity. The A and G entries involve no cash. Across his entire filing history, Berry has never recorded a buy, which makes the selling bias structural rather than episodic. The dollar volume is concentrated in MDB, with the June 16 cluster representing the largest recent discretionary selling event.
