Michael J. Berry, chief financial officer of MongoDB (MDB), has filed 90 Form 4 transactions across four companies, with a total sell value of $11.83 million and zero open-market purchases. The recent pattern is heavily weighted toward sales of MDB stock. On June 16, 2026 alone, Berry executed 16 separate "S" transactions, ranging from $1,091 to $400,408, with combined proceeds exceeding $1.9 million. The prior day, June 15, brought four more sales totaling roughly $489,000. These trades are small in individual size but frequent, suggesting a systematic disposition of shares rather than a single block sale.
The most recent filings include a gift of MDB shares on July 8, 2026, valued at $0, and a "F" transaction on July 1, 2026, where shares worth $2.38 million were withheld to cover tax obligations. That withholding is automatic and tied to equity vesting, not a discretionary sale. Berry also received a grant of HubSpot (HUBS) stock on June 16, 2026, valued at $0, which is compensation rather than a purchase.
Across all 90 filings, Berry has never bought shares on the open market. His activity consists entirely of sales, tax withholdings, grants, and gifts. The recent concentration of MDB sales in mid-June 2026, combined with the absence of any purchases, shows a consistent seller bias. The dollar values are moderate for a CFO, and the transactions are spread across many small lots, which is typical of a pre-arranged trading plan. No purchases have been recorded in the recent window, and the total buy value across all companies remains zero.
