The investigation is substantially over. They found absolutely nothing apparently but the noncash restatements.
The notion that JBII chose to reveal the notice yet lied about it is so laughable my ribs are about to burst. If any company was dumb enough to lie about the content of a Wells Notice the SEC would suspend (or halt) the stock faster than you can say $650 per ton in feedstock.
Notice any suspension or halt? No? Then the SEC was satisifed with JBII's 8k. Therefore, indirectly, the SEC just said to your face they found nothing (or nothing worth pursuing anyway) except the restatements from 2 years ago everybody already knew about.
The investigation is substantially over, and that's all that came out of it. Basically nothing.
