The SEC filing was just a compliance item to keep a 3 year old warrant issuance from expiring. Those warrants generate cash for the company and when looking at fully diluted numbers which were just reported are already baked in, so they will not be diluting when when exercised.
The registration statement filed today is merely a renewal of an outstanding registration statement covering the issuance of shares underlying warrants (exercisable at per share prices of $1.43 and greater) that were issued 3 years ago and remain outstanding. The underlying shares were previously registered but the registration statement is expiring under SEC rules and needs to be refreshed.
