Well, if you really did homework, you will see how wrong you are. NQ has almost the lowest forward P/E among its comparable firms( though I doubt there is any one that has a comparable model as opposed to NQ's ).
Plus, as a professional from buy side, what I can say is it's absurd and simply stupid to ignore non-GAAP earnings, which more thoroghly and precisely reflect the quality of the business operation. In many cases, even P/E is not appropriate or credible to evaluate firms of high growth like NQ; PE/G, EV/EBITDA or even P/S can be more suitible
