Rule 144 regulatory

"notice of proposed sale under Rule 144 for resale of securities"

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.

Option Granted financial

"Option Granted - 02/20/2018 and Option Granted - 09/01/2016"

Broker of record market

"Fidelity Brokerage Services LLC listed with an address as broker"

A broker of record is the single broker or firm officially authorized to manage an investor’s account, execute trades and receive related communications and fees on behalf of that account. It matters because whoever holds that designation controls who handles orders, gets paid for advice or commissions, and can access account information—similar to choosing a primary agent to handle your taxes or a primary doctor to coordinate care, which affects costs and how decisions are made.
