Paying the Piper...
Let me predict the future...
Citadel & Regent lead the pack into bankruptcy, essentially taking both companies private by stiffing shareholders and leaving the companies in the hands of the biggest creditors.
Once the "reorganization" is over, the "new" companies operate for a while, keeping a very close eye on expenses. No more cuts, but no help for the overworked, overextended people left on the payroll. They're supposed to be "thankful" that they're still employed.
In a year or so, the new owners "evaluate" the situation. If the returns are good, they think about taking the company public, with the promise of expanding their holdings and "extending our proven track record of good management to even more markets". The new owners use the stock offering to repay themselves for their original investment (plus interest), and hang onto enough stock to retain control of the company.
If returns aren't so good, they think about selling the company because "we're investors, not operators". The selling price will be their original investment (plus interest), and some stock in the new company. The new company will likely be one of the other groups who've either gone, or are, publicly held.
In other words, they'll either eat or be eaten. Thus, the public/private/public/private dance will continue...
