In the case of the UK water companies the parent fund was often involved in getting or making the loan e.g.
Water company does a debt bond issue, parent owning fund takes a % of the issue (enough so that the bond issue is a success at a good price), parent fund extracts all the funds raised as a dividend, and sells the % of the issue it own too
Right, so the “parent” posts a profit, and it comes (either tomorrow or next year) from revenue earned by the “child” that borrowed, trading revenue tomorrow (going to lenders) in exchange for cash today (going to “parents’” owners).
Without getting into the weeds, my point was that in order for owners to end up with cash in their pocket, the business has to earn a profit, at some point. And that profit must come from revenue (higher prices for customers) minus expenses (lower quantity/quality for customers).
You can insert a lender in there to shift when those cash flow changes happen, but the money must come from customers, eventually.
Barring any research and development that results in technology that will allow for lower expenses and/or increased production, but I do not think that is the case here.
No the business doesn’t have to make a profit it just needs enough revenue to service the debt
Of course what happens is many business geared this was don’t make a profit, fail their banking covenants, interest on the bond rises and eventually they go bust leaving lenders out of pocket

All while extracting management fees etc too
