PharmaCyte Biotech Inc (PMCB)

[Triple9]

After the $PMCB S-3 was filed I started looking into the reasons other pre-clinical biotechs filed S-3.

What I found was an interesting pattern. In two cases I found S-3s filed after a partnership was announced:

And in one case I found an S-3 filed before a partnership was announced:

Now S-3s are filed for various reasons of course, I just thought it was interesting as these are all biotechs.

It didn't take me very long to find these and I'm sure there must be dozens of other examples out there. Anyone know of other examples?
