"Filer Information | 144: Filer Information"

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.

Rule 144 notice regulatory

"144: Securities To Be Sold"

A Rule 144 notice is a public filing that an insider or holder of restricted stock submits when they plan to sell shares that aren’t freely tradable yet; it lists how many shares they intend to sell and under what conditions. For investors, it matters because it signals potential insider selling and an upcoming increase in shares available to the market—similar to someone announcing a big garage sale, which can affect supply and price expectations.
