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 financial

"This filing is for Founder Shares acquired by Kenneth Duda."

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.

attorney-in-fact regulatory

"as agent and attorney-in-fact for Kenneth Duda"

An attorney-in-fact is the person or entity given legal authority through a power of attorney to act on behalf of another for specific tasks, such as signing documents, voting shares, or handling transactions. For investors, this matters because it lets a trusted representative make timely decisions or complete paperwork when the owner cannot, much like handing keys to someone to run errands on your behalf—so checks on scope and limits of that authority are important.
