I tend to agree with you, Dog. Good things ought to be coming. However, our present expectations seems to be based on inference rather than evidence. Those who have done the best DD, IE, biowin, Sorhay, and others, present their case using logical inference based on financial documents. Some conclusions, or explanations, for a payout are positive ... but contradictory in their deductions.
Proof would be a document that reads, "Shareholders of BIOA stock will, after four years, receive payout of $22/share for the purchase of the shares in 2018."
Or, another possibility: "In 2018 BioAmber merged with XXX.co. The legal process took some time due to aaaa. As of <date> all BIOA shares will convert to KKKK at a market value of $22/share."
When we see something like this, we can rest easy. Until we see some direct proof ... the debate will continue.
