No way of knowing is the simple answer. Eli Lilly is on a crusade to swipe up as many companies as it can. At one point it was looking to clock in $1-5 Billion of M&A per quarter. ENZC would be a drop in the bucket for them... and if not them someone else.
I do think ENZC would be a great buyout opportunity as-is if someone was just looking for the tech.
