You'd have to read through that bloody great disclosure document and see if you can find what their debt is and come up with a rough interest figure ,then try and find if they have any tax losses to offset (may be complicated due to merger)-if not just subtract the company tax rate. Then have a look at whether they've given previous figures for the individual entites on depreciation etc... and make an estimate. personally I can't be bothered and will trade it on technicals.
After a quick look it appears CGC (the old business) has very little interest payment and the overall business should have less than 1 mill in D and A. (CGC has moreso than WWTS). The figures quoted for WWTS only go as far as EBIT for some reason so no way of telling their debt/tax situation unless it is mentioned elsewhere.
As I said I have only has a cursory glance at the figures but they appear to paint an incomplete picture to me.
