Value depends on EESO's proprietory formula. Not on current PPS. Even though this is not a drug company but its similar business model evaluation. Also EESO is like a startup company so any sale of the company has to take into accoutn potential fututre earnings..not current PPS. PPS in pink sheet can be way off. Like CNOA..their EPS is 35 cents yearly but trading at 28 cent. Does that mean they gonna sell at 28 cents on buyout, NO. Stock usually 10-15 times their earnings. but it can trade like less than 1 multiple of earnings. So how can evaulate a companies value just based on PPS?
