Going concern is an accounting standard requirement and failure to disclose could lead to auditors refusing to sign off on the financials, or potentially lead to investor fraud liabilities. It has nothing to do with forcing tender. Maybe the filler/toxin markets are not so hot anymore, as echoed on cafe pharma boards and earnings (EOLS took a 15% hit couple days ago).
I have the same belief as you. This is why I didn't sell 100% of my position. I only trimmed just enough that if this recovers, I will have broken even on RVNC as a whole; and it if it truly falls through, the impact on my ssa portfolio would be minimal and recoverable via other positions.
