Multiple hirings in the last few months (keeping an eye on Linkedin) including recent hires in Florida and Chicago. Looks like they are moving towards cell production locally and they are talking about share consolidation to possibly move up to a Nasdaq or Nyse listing. I don't think you bother moving up to a senior exchange if you're not progressing, what would be the point? Things must be happening in the background, maybe improved cell. Some of their newer hires are involved in R&D.
