Jerry, agree that the change of control provision is pretty standard in corporate compensation contracts. Generally, PSUs / RSUs / Options all accelerate and vest in full at a transaction.
The slightly less typical compensation behaviour is the repeated extension and suspension of warrants and options. The Board could (probably rightfully) claim that they want management to make long-term value maximising decisions, not short-term optimisation around personal compensation, and protect shareholders from sudden management-driven dilution.
I can buy those rationale - just about. I’d buy it more if / when we see the journal article publication and how much additional cohort segmentation they may have needed to do to make external control arms like-for-like with the original patient population plus the crossovers under new definitions of GBM.
