What Happened

• Dwight A. Merriman, a MongoDB (MDB) director, sold a total of 16,000 shares of MongoDB common stock in a series of open-market transactions executed July 14–16, 2026. The individual trade prices reported range around the low $300s (weighted-average prices and per-trade prices shown), with aggregate proceeds of approximately $5,180,466. The trades were reported as sales (transaction code S) and were made pursuant to a Rule 10b5-1 trading plan.

Key Details

• Dates: primary transactions on July 14, 2026 (multiple lots) and July 16, 2026 (multiple lots); Form 4 filed July 16, 2026.
• Shares sold: 16,000 total; aggregate proceeds ≈ $5.18 million.
• Price detail: individual reported trade prices in the filing include per-trade prices from about $316.52 up to ~$333.42; several footnotes state weighted-average ranges across multiple executions (examples include ~$316.28–316.90, ~$327.28–328.23, and ~$333.20–334.00).
• Ownership after transaction: not specified in the excerpt provided.
• Notable footnotes: F1 confirms the trades were executed under a Rule 10b5-1 plan; other footnotes note weighted-average pricing ranges and that some shares are held in entities (the Dwight A. Merriman Charitable Foundation and a 2012 family trust) over which Merriman has voting/investment power (the foundation shares are reported as having no pecuniary interest).
• Timeliness: The Form 4 was filed two days after the primary transaction date (filed July 16 for transactions reported July 14), consistent with typical Form 4 filing timing.

Context

• These were open-market sales executed under a pre-established 10b5-1 plan, which is a common mechanism for officers/directors to sell shares on a predetermined schedule and does not itself indicate current sentiment. For retail investors, purchases can be a stronger signal of insider confidence; sales are often routine (liquidity, diversification, tax planning) but should be considered alongside other data and filings.
