Yaya, the vote to authorize additional shares will not affect any PE calculation. Only when those shares are used to grant additonal employee options or when some of them may be sold to raise money do they get counted in the float.
If authorized and approved, they are not tradeble until Wave does something with them. Much in the same way Wave previously had 75 million shares outstanding. Just prior to the last funding in April, there was around 52million shareoutstanding. Add up all the shares that were used for the funding and that is the new number of shares outstanding, with 75 million shares still the number of total authorized shares.
But, to answer your question, I think the $40 package could carry a margin of 50-70%, not unlike other software from other well known vendors. Wave can go from zero, to decent numbers n a short period of time, as TPM's begin to ramp up with hockey stick adoption curves. I know you know all this, but it bears repeating for any new investors that are reading.
