Key Terms

Form 144, Class A, Founders Shares

3 terms

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.

Class A financial

"Class A | Fidelity Brokerage Services LLC"

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.

Founders Shares financial

"Founders Shares | Issuer | 04/20/2021"

Founders shares are a special block of a company’s stock originally given to the people who started the business; they often carry extra voting power or favorable terms compared with regular shares. For investors, these shares matter because they concentrate control and influence how future funding, ownership dilution, and decision-making will play out—think of founders shares as the steering wheel that can steer a company’s direction even as more passengers (investors) climb aboard.
