You don't need additional capital beyond operational maintenance expenses if you aren't expanding, but you do need the existing capital, and that means that either (1) the existing investors need to have their standards for profitability met, or (2) someone else who is interested in operating the assets without those profit demands needs to be willing to purchase the existing capital from the current owners before they decide that their profit requirements won't be met and sell it to someone with a desire to use it for something other than its current insufficiently-profitable use.
