VINCIARELLI PATRIZIO 4

What Happened
Patrizio Vinciarelli, a 10% owner of Vicor Corporation (VICR), sold a total of 700 shares in open-market transactions on July 6, 2026 for aggregate proceeds of approximately $211,681. The filing reports two disposals: 500 shares at a weighted-average price of $302.04 (≈ $151,018) and 200 shares at a weighted-average price of $303.31 (≈ $60,663).

Context
As a 10% owner and trustee, Vinciarelli is a significant insider but this transaction involves trust-held shares and a sale under a 10b5-1 plan—both common mechanisms for planned dispositions. Sales do not necessarily signal negative views about the company; they often reflect personal or estate planning needs.
