Insights
CEO sold 20,000 Vicor shares under a pre-set 10b5‑1 plan while retaining a very large stake.
Patrizio Vinciarelli, Vicor’s Chairman, CEO, and more‑than‑10% owner, reported open‑market sales totaling 20,000 common shares on June 17, 2026. Sale prices, disclosed as weighted averages, span from roughly $321.54 to $338.21 per share across multiple transaction blocks.
The report shows he continues to hold 8,567,790 shares directly and 167,125 shares indirectly as trustee of an irrevocable trust for his child. Relative to these reported holdings, the sale size appears small, suggesting a routine liquidity event rather than a major change in exposure.
The footnotes state that the trades occurred pursuant to a Rule 10b5‑1 trading plan adopted on February 26, 2026. Such plans are established in advance and executed automatically, so the timing of these sales typically carries less informational weight than fully discretionary trades. No derivative exercises or new option grants are reported in this filing.

Rule 10b5-1 trading plan regulatory
"This sale was effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on February 26, 2026."
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
weighted average price financial
"The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions..."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
Irrevocable Trust financial
"These shares are held by the reporting person as Trustee of the Patrizio Vinciarelli Irrevocable Trust U/A Dated 12/21/2012..."
An irrevocable trust is a legal arrangement where an owner transfers assets into a separate entity managed by a trustee and gives up the power to modify or reclaim those assets. For investors it matters because putting stock or other holdings into such a trust can change who controls and benefits from the assets, affect taxes and creditor protection, and influence how easy it is to sell or value those holdings—like placing valuables in a locked safe overseen by someone else.
open-market sale financial
"transaction_action": "open-market sale","transaction_code_description": "Sale in open market or private transaction""
An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

FAQ
Were the June 17, 2026 VICR insider sales made under a Rule 10b5-1 trading plan?
Yes. A footnote states the sale was effected under a Rule 10b5‑1 trading plan adopted on February 26, 2026. Such pre‑arranged plans execute trades automatically based on preset instructions, which can make the timing less indicative of the insider’s short‑term market view.
What indirect VICR holdings does the CEO report on this Form 4?
The filing reports 167,125 shares held indirectly as trustee of the Patrizio Vinciarelli Irrevocable Trust U/A dated December 21, 2012. The trust was established for the benefit of his child, and these shares are listed separately from his direct common stock ownership.
Does this VICR Form 4 include any option exercises or derivative transactions?
