The initial stage, the SISP, was directed more to a financial buyer to take over BioAmber as a whole, including staff and management. It's very clear there was no interest retaining personnel, most likely management, and BioAmber's corporate structure. A financial buyer only want to buy a company and flip it 5 years down the road for a profit.
In the strategic scenario we are in now, the buyer wants the assets because they believe it will create a competitive advantage. They'll typically purchase at premium.
All we are waiting for is an offical number and judging from the document forensics work that has been done here, its a 9 digit number.
