VICOR (VICR) 10% Owner Patrizio Vinciarelli Sells 20,000 Shares
What Happened
- Patrizio Vinciarelli, reported as a 10% owner (shares held by him as trustee of an irrevocable trust), sold a total of 20,000 VICR shares in open-market transactions on July 1, 2026. The individual sales were executed at prices reported between roughly $344.50 and $366.71; the aggregate proceeds were about $7,133,640 (average ≈ $356.68 per share). All transactions are recorded as dispositions (sales).
Key Details
- Transaction date: July 1, 2026 (Form 4 filed July 6, 2026).
- Total sold: 20,000 shares for total gross proceeds of $7,133,640 (≈ $356.68/share).
- Sale method: Open market (multiple trades; many line items report weighted-average prices with price ranges in footnotes).
- Notable footnotes: F1 — shares held by the Patrizio Vinciarelli Irrevocable Trust for the benefit of his child; F2 — at least one sale was effected pursuant to a Rule 10b5-1 trading plan adopted Feb 26, 2026; other footnotes (F3–F21) disclose weighted-average prices and the per-trade price ranges and an undertaking to provide detail on the number of shares sold at each price upon request.
- Shares owned after transaction: not specified in the provided excerpt of the filing.
- Timeliness: Filing occurred five calendar days after the trades (filed July 6 for July 1 trades), which is outside the typical 2-business-day Form 4 reporting window and may be considered late.
Context
- These are disposals by a 10% owner (significant holder) rather than an executive purchase. Sales executed under a pre-established 10b5-1 plan and held in a trust can be routine or part of pre-arranged liquidity; they do not, by themselves, indicate insider knowledge of company fundamentals.
- Retail investors should view this as a material insider sale (sizeable dollar amount) but not necessarily a negative signal on its own. For a fuller picture, check recent company news, executive transactions, and the filer’s remaining ownership disclosed elsewhere in the full Form 4 or proxy filings.
