There is no evidence that someone (entity) purchased all the shares in the shelf registration - unless any offer was filed as delayed, then, it would have been filed as continuous, which most likely would have impacted the PPS even more. Lastly, any offer through a Shelf Registration must be filed (2) days before the offering - most likely a Form S-3, and would also be filed in the 8-K. Lastly, if Pluristem received a guarantee of $80 million, why would they have a need to offer 9 million shares recently - this would make no sense!
