At last check, if has not been filed. Per SEC guidelines for an extension, a Company has 15 calendar days from the due date to file, which would be by April 15th.
Maybe they shorted their own stock when they new that their partner would be dilluting the PPS and then this way they can get into a share buy back process and release then info with the financials. A sneaky move but could be a very good possibility, if somone was going to sell alot of shares of my company they aquired when i was weak i wouoldnt let them get a high price for them out of spite.
