I wouldn't be able to say, but an educated guess would say, unlikely. The fact they are struggling to get investment would suggest not. Generally clubs don't make profit, so dividends would be minimal. The value would be in getting a PL club on the cheap (FSG got LFC for a comparative pittance and would likely sell it for £3billion if they put it up for sale tomorrow). The problem for Everton is there entire existence is dependent on Sky money. Strip that out and they make £56m revenue a year. Staff costs last year were nearly 3 times that (£159m). TV money is about 5-10 million per club in the championship, so a huge drop. So, if relegation came along they would need to offload most of their playing staff.
So, an investor would have to consider
1. A team that has been hovering over relegation for 3 seasons running
2. Has piss poor revenue streams
3. Is dependent on TV money
4. Has an expensive and ineffective squad
5. A 'relegation specialist' in charge
6. Massive debts
7. An incomplete stadium
8. Is embroiled with dubious lenders
9. Is in direct competition with a behemoth of the game
10. Is awaiting more point deductions next season
11. Has failed FFP (P&S) 3 seasons running and looking good for a 4th.
12. Hasn't made a profit in 8 years
It would be a lousy investor who looked at that and thought 'bargain!'. It just requires one bad season to completely wipe the value of the club out and incur massive, massive, loses.
