All the science is great and plenty of speculation about how it could change the world and make millions for shareholders, but IMO the bottom line is, until they do deals it's just not going to re-rate. It's been years since they did a deal, so at the moment it looks like a lab doing great tech, chasing improvement after improvement, generation after generation of products, but taking nothing commercial. If valuations, for the most part, are done on sustainable cash flows, then how do you value this, apart from spec comparisons to others that have done deals?

I love the science, am fascinated by it, and have been in this stock for a decade or so, made good money from time-to-time so am happy, but it has never realised it's potential because they can't get a signature on the bottom line. Hopefully all that will change - one day ?
