Only part of that is attributed to share holders and it is all about profit. Rotman;s is a mature business that will not demand a high valuation multiple. So .5x to 1x revenue is not out of the norm unless they are pulling in crazy profits.
Look at it this way, even at 10% net which is high for the industry that is say $3.5M net income, puts EPS at .003 so 10x puts it at .03
Now if they are at the industry norm around 4% that's EPS of .0014 which at 20x is .025
And that is ignoring that combined with VYST it may show a loss, and that is ignoring the minority interest adjustment which will make EPS lower
