Maybe 2020.
Most of the new staff ads have very little in the way of shares, whether purchased outright or optioned. As such, IMO, they are not incented to get the ball rolling too fast and maximize share value. Doing so too early only nets them a couple multiples of their salaries per their employment agreements. They will need to go to the shareholders for more share authorization generally {at current prices, they should be able to raise $1.5-$2MM from the new funders once the S-1 is effective [30 day initial review expires next week] and who knows what their plan or burn rate is thereafter, requireing more shares and a 3+ month AGM lead time} and more ESOP-like authorization specifically to reinstate options surrendered and gain even more. Probably need a couple of years of pocket-lining. If they were confident in their abilities to gain a good valuation and a future share price, one would think they would be buying shares at these levels, whether by PPL or in the open market. Either they are as poor as church mice, have no confidence in the future valuation or feel confident in the ability to grant themselves all the shares they'll personally need.
When they come out with the proxy, shareholders should once again submit a question to rescind the preferred authorization. It's clear to me, despite the lawyers saying that it could benefit a buyout, that the preferred authorization is nothing more than a 'poison pill' and I, for one, would welcome the ability to consider any takeover proposal. Enough is enough.
