Form 144 regulatory

"lists proposed resale dates and share counts under Rule 144"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

Exercise of options under a registered plan financial

"Exercise of options under a registered plan resulting in sales dated 05/11/2026"

Gross proceeds financial

"monetary figures shown adjacent to sale dates correspond to gross proceeds"

The total amount of cash a company receives from a financing event or sale before any fees, expenses, taxes or deductions are taken out. Investors watch gross proceeds because it shows the raw scale of new capital being raised—think of it as the paycheck amount before withholdings—which helps assess how much funding is available for operations, growth, debt payoff or how much shareholder dilution might occur once costs are removed.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What does VICR's Form 144 filing mean?

It notifies the SEC of proposed resale of restricted or control securities. The filing lists intended sales tied to option exercises on 05/11/2026 and prior reported dispositions; it is a regulatory disclosure of planned transactions, not proof of completed sales.

How many shares and proceeds are shown for the 05/11/2026 entries?

The excerpt shows two exercise-related entries on 05/11/2026 listing 96 and 4,963 shares respectively, with associated gross proceeds reported in the filing lines for those exercises and sales.

Who is named as a seller in the filing excerpt?

The filing lists Quentin Fendelet with addresses and multiple past sale dates: 05/06/2026, 03/02/2026, and 02/23/2026, each with share counts and gross dollar amounts shown in the excerpt.

Does this Form 144 confirm the sales were completed?

No. Form 144 indicates intent to sell or resell under Rule 144 and reports proposed transactions and exercise activity; it does not by itself prove that the listed sales have been completed or that Rule 144 conditions were satisfied.

Are the dollar amounts in the excerpt gross proceeds?

Yes. The lines adjacent to each sale date display monetary figures that correspond to gross proceeds from the reported dispositions, shown for example alongside the 05/06/2026, 03/02/2026, and 02/23/2026 entries.
