Vicor (VICR) 10% Owner Patrizio Vinciarelli Sells 50,000 Shares

What Happened Patrizio Vinciarelli, a reported 10% owner of Vicor Corporation (VICR), sold a total of 50,000 shares in open-market transactions on March 11, 2026. The sales were executed in multiple lots with reported per-share prices (weighted averages for groups of trades) ranging roughly from $167.75 up to $180.54; total reported proceeds across all lots were about $8.87 million. These transactions are reported as sales (code S).

Vinciarelli holds some of these shares as trustee of the Patrizio Vinciarelli Irrevocable Trust (per the filing). At least one of the sales was made pursuant to a Rule 10b5-1 trading plan established on November 3, 2025. The Form 4 was filed the next day (Mar 12, 2026), which appears timely.

  • Holdings: shares were held in part by the reporting person as Trustee of an irrevocable trust (footnote F1). The filing does not list the total shares owned following these transactions in the material you provided.

Context

  • This is insider selling by a 10% owner (not a routine executive buy signal). Sales under a pre-established 10b5-1 plan are often pre-planned and do not necessarily indicate a change in view about the company.
  • For retail investors: purchases by insiders generally carry more positive interpretive weight than routine sales. These sales were executed across multiple trades and price ranges; the reporting person offered to provide detailed per-price breakdowns on request in the filing footnotes.
