I think both. Totally a guess, obviously, but I think Aruda may have thought, "Damn! That thing I worked on is actually working!" It seemed to have happened so fast, that I think you're point is correct.
I'm not sure I understand your point. Menon did not give up shares for a piece of K revenues.
Menon parted with 1/2 of his shares (approximately) AND 1/2 of his royalty on K revenues.
My view is that Menon had other options, but chose to go with the deal as announced to allow CTIX to proceed with business uninterrupted. I think Menon made a huge personal sacrifice for the benefit of the company and shareholders.
I would say that the Aruda deal tells us one thing for sure. Dr. M believes in "K". If he didn't believe, he could have tried to structured the deal to be more heavily weighted toward "K" results. The dispute was over one drug and the settlement was for half of Dr. M's ownership in the entire company. Could you see a large Pharma inking that deal? I believe it was also motivated by a desire to remove a possible roadblock to future deals prior to uplisting plans.
