1. Going private - they don't need a CEO because they go private soon (weeks, not months).
2. Staying public, really looking for a CEO - they really did get caught with their pants down when Miller resigned, and they really are doing a search for a new CEO. That could take months. Wouldn't there be some word out on the street within the industry though? I am not an E&P insider, but there seem to be a few around here - is there any evidence that they're out doing a search? Rumors about who might be considered, etc?
3. Staying public, and have a handpicked guy waiting in the wings - they pushed Miller out, have a succession plan in place, and are waiting for something else (what, I have no idea) before announcing the new CEO.
If this is still a public company at the end of Feb, I'd be surprised if it doesn't have a CEO by then. There is also that March analyst meeting to think about (if that is even still going to happen) - if they are still staying public, they would want the new CEO in place then to meet the Analysts, etc. When would we expect a specific date to be set for that meeting (how much runway do they give people to arrange travel, etc)? No later than the end of Feb?
