Insights

Securities Attorney

Form 144 records a proposed resale of common shares via a brokerage on Nasdaq.

The filing is a regulatory notice of an intended resale: it lists the broker (Fidelity Brokerage Services LLC), the market (NASDAQ), and an intended date (05/05/2026). A Form 144 itself does not confirm completed sales.

Because the excerpt includes multiple historical restricted stock vesting entries with discrete share counts, subsequent trade reports or Form 4/5 filings would confirm actual dispositions; this filing only notifies the SEC of intent to sell.

Form 144 regulatory

"144: Securities To Be Sold"

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.

Restricted Stock Vesting financial

"08/01/2018 | Restricted Stock Vesting | Issuer"

Restricted stock vesting is the timetable and conditions under which shares granted to employees or insiders become fully owned and can be sold, typically requiring continued work or meeting performance goals. It matters to investors because large blocks of shares can become tradable at once, which can change share supply and price, and because vesting aligns insiders’ incentives with the company’s long‑term performance—think of it like a timed unlock that both rewards and locks in key people.
