Not sure I know exactly what you mean, but if you divide the number of shares there are now by the number of shares there will be (1 billion divided by 1.35 billion), you get the relative value of the new shares compared to the old ones - 74%.

And if you divide the # of shares after dilution by the number before (1.35 B divided by 1 , you get the ratio of 1.35 -- multiply it by the number you have now, and buy the difference. And you'll have the same percentage of the company that you have now.

Is that what you mean?
