When a CEO leaves a business/company unless its to retire or take a dream job it normally means thing are not good. So in that case i would say its bad news.
Sadly for us we have been run badly for some time now.
You can look at it many, many ways, without knowing the reality behind the actual facts.
A CEO can be forced out because of job requirements, and other senior appointments (Sir Les) that then make the job less appealing, or Beard too expensive for the job needed.
All conjecture and speculation.
