I talked with Dr. Prather on the phone the other day, he is a very helpful and friendly guy. Pluristem does not intend to do another reverse split as they believe that their product will be in phase 2 clinical trials after a year (phase 1 safety trials will take ~1 year to complete). If the stock does fall under a dollar nasdaq will give them 6 months to get back over a dollar, and if necessary, give another 6 month extension. By then, the investment community will have seen the huge potential of this company and it will no longer be a concern. Furthermore, pluristem is considering licensing their 3d bioreactor for expansion of various types of cells, like blood cells for leukemia patients, for example. This would provide an extra stream of revenue. Lastly, the company has a grant pending from the Israeli government which they have already approved but not given yet (working through the red tape I guess).
Dr. Prather actually called me, on his own dime so he is not elusive and I do believe this company believes in what they do and that they can help people.
If anyone wants a copy of their presentation they gave at the noble conference, feel free to email me at jeff at toastyaroma dot com
