4 terms

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.

pro rata distribution financial

"The reported transaction was a pro rata distribution from Atlas Crest"

A pro rata distribution is when a company or organization shares out money, assets, or benefits evenly among all eligible people based on their size or share. For example, if a company makes a profit and distributes it to shareholders, each person gets a portion proportional to how many shares they own. It ensures everyone gets their fair part based on their ownership or stake.

warrants financial

"Warrants | Pershing Advisor Solutions 95 CHRISTOPHER COLUMBUS DR"

Warrants are special documents that give you the right to buy a company's stock at a set price before a certain date. They are often used as a way for companies to attract investors or raise money, and their value can increase if the company's stock price goes up.

Account Stakeholder financial

"Achill Holdings LLC account in which Michael G. Spellacy is an authorized individual and Account Stakeholder."
