most probably half of the stash is in the hands of Evan Inc.
1-2.8%
How can this be, if he got all the stash at the premine ?
He didn't. I don't know where you heard that.
A simple compound-interest calculation puts it close to 50%. Start with 100% of the stash when there were 2 million coins (the premine). Then apply the 45% interest on the mining and re-capitalize it until you reach 7 million coins or so.
