read the 2Q report, transcripts and articles; see how bad it was. After it tanked 30% on worst case scenario, the stock was STILL PRICED AT 3.10. The sky was absolutely falling on these guys.
Since then it looks like they have pivoted fantastically on mobile, positive break from FB dependence, real money gaming is intriguing and "real" (though still down the road as the UK gaming is just an estimated tiny market, and US is a ways away -- but not that far). They are done wasting cash on bad acquisitions; they have restructured with lay-offs, studio and bad game closing, reducing their huge R&D.
They still have amazing game usage and are expanding outside of the FB platform. Mobile advertising will make them money and get them away from being dependent on virtual goods...
The stock is priced under what it was directly after 2Q apocalypse, guidance and expectations have been drastically reduced, and there is no reason to believe the cash floor is diminishing, protecting the last $1.70 a share or so.
I hate holding major positions through earnings, but I'm doing it this time.
Needham, btw appears to have their finger nicely on the pulse of ZNGA. They were bearish to neutral on ZNGA in early 2012 and then upgraded to buy after 3Q earning (Oct 25th). I think there guy gets it.
