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.

stock grant financial

"Common | 07/24/2024 | stock grant | Tsakos Energy Navigation Limited"

A stock grant is an award of company shares given to an individual, often as part of compensation for employees or executives. It matters to investors because grants can change the number of shares outstanding (dilution) and signal how company leaders are being paid and motivated—think of it like receiving a slice of the company as part of your paycheck, which can affect ownership and future share supply.
