What the price assumes
Your guesses, our math
Move the sliders to your own view of PRTA. Starting points are the company's recent numbers (it isn't profitable yet, so the margin starts at a 10% guess).
Sales in 5 years$202M
Profit in 5 years$20M
Price these guesses point to$6.22-26% vs $8.40 todayAbout -5.8% a year, before dividends
What today's price needs: with a 10% margin and a 15x P/E, sales would have to grow about 38% a year for 5 years just to match today's price.
Simple math on your guesses, not a forecast or a price target. Real results depend on many things these sliders leave out.

50 is neutral. Buying by more insiders, top executives and bigger stakes raises it. Selling lowers it; pre-planned sales count less.
