What does VICR's Form 144 for 50,000 shares mean?

It notifies the SEC of a proposed resale of 50,000 shares of Common Stock. The form signals an insider intends to sell shares under applicable resale rules rather than reporting a new grant or company issuance.

Who executed the 10b5-1 sales listed in the filing for VICR?

The excerpt identifies Patrizio Vinciarelli as the seller for multiple 10b5-1 transactions, with individual sales recorded on dates including 03/12/2026 and 03/11/2026.

How many shares did Patrizio Vinciarelli sell in the March 2026 trades?

The filing shows multiple March 2026 entries of 50,000 shares each on several dates. Each listed trade includes an associated dollar amount reflecting gross proceeds for that trade.

Do the listed dollar amounts represent proceeds from the sales?

Yes; each trade row pairs a share count with a dollar figure (for example, 50,000 shares with $8,372,990.00), which are presented as the trade amounts in the excerpt.

Does this Form 144 change VICR's outstanding share count or company actions?
