Form 144 regulatory

"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.

Option Granted financial

"Option Granted - 11/29/2021"

Class A market

"Class A | 04/08/2026 | Option Granted"

Class A denotes a specific group of a company’s shares that carry a particular set of rights—most commonly different voting power or dividend priority compared with other share classes. Think of it like different seats on a bus where some seats let you steer and others only ride: knowing whether a share is Class A tells investors how much influence they have over company decisions and how returns might be distributed, which affects control and value.

Cash financial
