Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

10b5-1 Sales regulatory

"10b5-1 Sales for THE PER ARTUR BERGMAN REVOCABLE TRUST"

10b5-1 sales are pre-arranged stock-trading plans that let company insiders automatically buy or sell shares according to a fixed schedule or formula, even if they later learn confidential information. Think of it as setting up an automatic thermostat for trades: it creates a clear, documented path that can protect insiders from insider-trading accusations and gives investors a signal about predictable insider activity—though it can also simply be a way for insiders to diversify or raise cash.

Founders Shares financial

"Common | 03/10/2011 | Founders Shares"

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.
