Key Terms

Form 144, Founder Shares, Grantor Annuity Trust #1, J.P. Morgan Securities LLC

4 terms

Form 144 regulatory

"144: Securities Sold During The Past 3 Months"

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 Shares market

"Founder Shares | Issuer | 180000 | 12/31/2013"

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.

The excerpt names Caroline Cochran and Jacob DeWitte, plus associated Grantor Annuity Trust #1 entities. It also references Founder shares acquired on 12/31/2013 in the transfer history.

Does the filing state how the shares will be sold or who receives proceeds?

The provided excerpt lists a placement agent, J.P. Morgan Securities LLC, and contains numeric cover entries, but it does not state explicit proceeds allocation or the exact sale method in the visible lines.

Are the listed founder shares and transfers part of the same transaction?
