In a direct stock offering/underwritten offering that would be the case, but microcap bios usually have to do private placements/PIPES, in which cash the financing entity gets all the shares and warrants.
Larger bio companies are sometimes able to do direct/underwritten stock offerings, but you don't see that often with micro caps, I guess because the deal is too small to be worth the underwritter's time.
However, the last PYMX financing (April 2011) was underwritten, and in such a deal the underwriters distribute the stock/warrants to their various clients. Prior to that, PYMX did a registered public offering (Nov 2009). If PYMX could do an underwritten or direct offering like these, perhaps Nic might see this as a viable option to raise money after a R/S. But issuing almost 50% additional shares in any type of financing to get a measly $17 mil doesn't seem like something that would be his first choice, especially when he can do a favorable non-dilutive pharma partnership deal that raises a lot more cash, and doesn't risk creating large equity holders who might then demand seats on the BOD, or otherwise undercut his autonomy in running the company.
