Form 144 regulatory

"Form 144 notice for proposed sale of restricted or control securities"

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.

Founder Stock financial

"Securities To Be Sold listing shows 'Founder Stock' class"

Revocable Trust legal

"Seller identified as 'James Henry Litinsky Revocable Trust' in the filing"

A revocable trust is a legal arrangement where the person who creates it keeps control and can change or cancel the trust at any time, while naming who will manage and receive the assets later. Think of it like a flexible folder for your investments and property that can be relabeled or reworked as circumstances change; it matters to investors because it determines how ownership is recorded, how easily assets transfer on incapacity or death, and whether holdings bypass public probate proceedings.
