SpongeBob, it means that the old accounting firm has found something in the filing which, if they sign off, could get them in trouble, so they won't sign off. In other words, they're covering their ass. They're responsible for the accuracy of that 10K.
If this is true then I predicted this. SPNG will announce that the accountant will not sign off, due to the firing (the real reason is that the numbers don't add up). Then SPNG will announce that Deloite is taking over the audit but that of course it will be several weeks before the 10K comes. 10K never comes and SPNG is a pinkie. At least it won't be under a penny, thanks to the R/S.
Look at the bright side, if the 10K is late (and they will turn out a 10K) that just means they are late, they get an 'E' and they aren't going to get to uplist to the NASDAQ, which I suspected that wasn't their goal anyway (probably got an offer and are selling the company).
No uplist means no RS is needed or called for. Not the end of the world as some are trying to hype and scream.
