Leo certainly believes a deal is at hand, and is hustling to make one. But like everything else, plans fall through. This is one the several risks we take. And a lot of stuff doesn't go to plan. But it's go-time on this, has been since late 2017 when we started cutting expenses and trials/research. There was no bidding war, no "20 BPs lined up to partner with us". It's not that easy and this is not fantasy world. Confirmation bias is not an investor's friend.
By my estimate we should hear about BTD, yes or no, by early November at latest. Deal terms would hinge on that. The early October share sale agreement has those 30 and 90 day clauses in there fits that reason, because of the timeframe he thinks is viable for each.
