To value a Pink, you have use other Pinks. Comparing with Amazon or even George Clooney's sale aren't good comparisons.
But to you question, yes if $20M in sales, I would still use 5X and once more mature, use 2X. It's growth potential especially if it hits $20M in 2017 will command 5X in my estimation, so given no further dilution than now, the PPS could be $100M / 3B shares (factors in ownership structure and debtor dilution). $.033 per share (the high back earlier this year. Now if shareholders ignore the ownership details, it could trade up to 4X that like it is now. That's $.13/.14 possible.
Just need $20M this year. Is it possible? Yes. Is it reasonable? With only $300K for first qtr, it seems a little far-fetched, especially in view of the earlier qtr at $363K (and most of those sales were near the end of the qtr). That's a clear downtrend, not up. But everyone gets to project as they wish. I'm sticking with $2M with an optimistic $600K for second qtr and the rest in the second half.
