Again it depends. And I have never in my 27 year Wall St. career had someone ask at what N.I./ share or EPS at which I would exit. Without a relative price exit who gives a crap what the EPS is. For example, it is earning $4 per share; great what is my price exit? Still, way underfollowed and so trading at some crazy discount; let's say something absurd, but for entertainment, 1 time. What the heck would I sell at $4 even if that is a 40 bagger? Now let's say it is still a $4 EPS and trading at 10 times I might consider it depending on what upside I still felt was left.
I am not saying I expect these numbers just trying to illustrate why your question makes no sense.
