It's probably a lot of work, the past 2 CEOs have been unpopular and according to their last 10Q the company is broke.
And the current 10-Q is past-due. They filed an NT to get an extra 5 days for filing, but those 5 days have come and gone.
Either they just can't comply with securities regulations, or they just don't care. I think the pump and dump, and resulting SEC suspension, in ALTO clearly demonstrates that.
