The posted financials show not only profits overall at the locations but that they are covering corporate overhead as well. Yes corporate overhead may be artificially low because of the lack of corporate executive payroll but none the less it is being covered.
I only know that they are making money as a whole per financials etc. It is possible that some are not profitable but based on PRs they have stated that they were cash flow positive and that they had reached a sustainable level of profits. So as a whole and in most situations they are profitable and i assume that they are all so but all that is verifiable is that they are as a whole.
