IPMN -- I think the biofuel operation is on autopilot and will continue to make money hand over fist. The loss of the CEO, however, concerns me for the wild cards. I don't know a lot about his day to day role in the technical nature of any of this, but from the very little I sense is that this adds a layer of risk to the growth prospects outside of the biofuel operations but not the biofuel operations themselves.
In the end, IPMN right now is priced as if total death is a 75%+ probability as IPMN, IMO, as part of a diversified portfolio is a screaming fist-pounding buy at this level. Sure, it has risks, but with a forward PE I see as cheap as 1 with really nice growth the risk/reward ratio is off the scale. We'll know more with the next earnings report due in a month which I think will be another quarter of huge sales and earnings, and a move into new 52 week highs wouldn't surprise me at all.
