Insights
Vicor’s CEO sold 20,000 shares under a pre-planned Rule 10b5-1 program, while retaining a very large position.
Patrizio Vinciarelli, Vicor’s Chairman, CEO and a more-than-10% holder, reported selling 20,000 common shares on June 25, 2026 in 15 open-market trades. Reported prices span the low-to-mid $300 range, with individual weighted-average prices up to about $342.51 per share.
The filing states the sales were made pursuant to a Rule 10b5-1 trading plan adopted on February 26, 2026. Such plans are pre-arranged and executed automatically, which generally indicates a structured diversification or liquidity program rather than ad hoc timing decisions.
Following these transactions, Vinciarelli still holds 8,467,090 shares directly and 167,125 shares indirectly as trustee of an irrevocable trust. In proportion to these reported holdings, the 20,000 shares sold appear modest, so the disclosure mainly updates investors on incremental, planned selling activity rather than signaling a major change in insider ownership.

Rule 10b5-1 trading plan financial
"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."
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.
open-market sale financial
"transaction_action: open-market sale"
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.
irrevocable trust financial
"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.
