You are correct, but the gist of the matter is that IPIX has no current streams of revenue nor ever has - though that could be changing in the near future if B proves effective against CV19.
They also have grant money expectations soon, but in the end no steady stream of revenues - YET.
When they do start coming, I have worked up dividend expectations and they are quite astounding should B and K perform and capture even very conservative portions of the major revenue streams in which they will be competing. Shocking dividends that would make me a rich man yearly with no need of ever selling stock.
