Dwight A. Merriman has filed 109 Form 4 transactions, all in a single company: MongoDB (MDB). The pattern is entirely one-directional. Across all filings, he has reported zero open-market purchases and zero acquisitions. His total sell value is $79,364,133.57, and every one of his 25 most recent trades is an open-market sale (code S).
The recent selling is clustered and substantial. On October 8, 2026, he filed three sales totaling roughly $4.68 million, with the largest single transaction at $3,458,207.44. The next day, October 9, he sold another $377,000. Prior to that, August 17, 2026, was a heavy day: seven separate sales ranging from $36,390.40 to $986,365.54, summing to about $2.71 million.

Merriman has not bought a single share of MDB in any of the 109 filings. His activity is exclusively dispositive, with sales spread across at least five separate trading days in the last four months of the reported window. The dollar values vary widely, from tens of thousands to over three million per transaction, but the direction is consistent. There is no purchase activity to offset the selling, and no option exercises or grants appear in the recent trades. The record shows a seller who has reduced his position in MongoDB repeatedly and in size.
