As far as the delinquent 10q, perhaps it makes sense for it to be a complete 10q at the moment of possible corporate transformation, in order that the books do not need further modification thereafter.
Anytime a company enters into a major transaction with or involving another party, you want to make sure your books are clean. The fact that the delay is a tax issue, which normally would just be disclosed as a contingent liability and not hold up the 10Q, it seems they are intent on resolving this before the release. But if f this is a large tax obligation in dispute, I doubt it’s resolved within just a few weeks.
