It means the Shell got reinstated-no
It means Duncan-Jeffy having paid $600, the state of Nevada renewed the business license of the company. A FINRA requirement to approve a corporate action. A Shell can't be back flipped into by another scam, if the underlying company of the stock doesn't have a business license in a State. That problem has been solved. Our hero Duncan-Jeffy can now put the Shell up for sale.
The state of Nevada could care less about whether the stock associated with a business is a Shell or otherwise.
Neither has the SEC at the speed of a turtle ever dislisted this delinquent scam - even though all conditions have been met for delisting. A Shell or any other form of stock can not be reinstated by the SEC if it has never been delisted. Actually, we should change speed from turtle to snail.
