Financially Ubisoft is the studio that has been doing the best this generation after Activision.
EA owns part of the voting but Ubisoft has been aware of that for a long time and put some protection around. A nice chunk of Ubisoft stock is in the hands of the Guilmaut brothers too ( the CEO is one of them).
The company is currently valued at 2.7B Euros too, which is little over 4 Billion dollars.
To make a successfull offer EA would have to offer a substantial premium over that.....
It would be tough for EA to convince Ubisoft shareholders that they can do a better job managing the company than the current Ubisoft management does.
Ubisoft stock price has gone up over 240% over the last 2 years.
By comparison EA stock price has been flat over the same period, and the same for Take Two.
