PWC didn't just "put out" the $4.34M, they went through two rigorous bidding processes under the watchful eyes of secured creditors owed $40M, and that was the winning bid for the assets of the company. Then, they put it in a motion to the courts, and it was ordered to happen without objection from anybody, including the secured creditors and other companies who were owed money.
So, the company's hired appraiser said the plant was worth more, and at a time the company was trying to survive and coax some entity with money to toss in and help them do that. Shocking, eh? Too bad it didn't work out.
Ignoring the court documentation in favor of presentation material from an entity that was not involved in the proceedings whatsoever that says a company that did not own BioAmber sold it is a horrible investment strategy. They even state in a disclaimer that it might be BS (paraphrasing, of course). Good luck with that.
I swear I’ll never use the phrase “you can’t make this stuff up” ever again after being on the OTC. Apparently you can.
