No.
Should the situation remain as is, there will never be an end. Not in this lifetime, not in a thousand lifetimes.
For it to "end", there will need to be a definitive material corporate event executing on BioAmber Inc.'s shares or some similar verifiable and quantifiable event that supersedes speculative written or verbal statements. This would need to be a watershed event that completely shatters and removes any doubt. That there is still doubt is the most obvious and glaring clue that no watershed event to date has transpired.
An amendment to articles would have or be one such event, for example.
Incidentally, some brokers have communicated to BioAmber Inc. shareholders that they cannot close their positions even if the shareholder wanted to (which must necessarily be requested), as the shares have not yet been deemed worthless, notwithstanding a value of N/A. In other words, value and worth are two different things.
Again, should the situation remain as is, the story will continue forever.
