Rule 144 regulatory

"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.

Founder Shares technical

"Founder Shares"

Founder shares are the ownership stakes given to the people who start a company, often with extra voting power or protections compared with ordinary shares. For investors, they matter because founders’ control and incentives influence decisions about strategy, hiring, and whether the company sells or stays independent — like a family that keeps majority voting rights in a household decision. High founder ownership can mean stable leadership but also a risk that outside shareholders have less influence.

Conversion technical

"Conversion"

Conversion is the exchange of one type of financial instrument for another, most commonly turning convertible bonds or preferred shares into common stock. It matters to investors because conversion changes the number of outstanding shares and ownership stakes—like trading a coupon for a slice of a company—potentially reducing each existing owner's portion, affecting per-share earnings, voting power and the market value of the stock.
