I read that as well, in fact it was mentioned twice in their 10-Q, but they have also mentioned that part of the reason they filed for bankruptcy was to protect the interests of their shareholders. The language definitely exists, however I believe this only points to the imminent demise of ENDRQ as a ticker, not a demise of the stock altogether. Most likely holdings would be transferred to a new ticker once they emerge from bankruptcy.
"All of the Company's existing equity securities, including its shares of common stock and preferred stock, will be cancelled, without receiving any distribution."
The most important part of the statement being EXISTING, this statement was made before the ticker became ENDRQ as well.... and it was absolutely true, END was cancelled, but were the shareholders left out in the cold? Nope.
