The strategy is to strip the company to the bones. Anything that can be sold will be sold (Buildings, furniture, IP). And if the company needs it to operate it will be leased back at a monthly rate. All cash this generates is pulled from the company to the PE firm. If they can they will saddle the company with a debt for the purchase of itself, so they can have the company not only pay that back, but with interest (a leveraged buyout). Some of these assets sold off can easily go to other subsidiaries of the same PE firm.. such as real estate. Assuring their long term profitability.
Add in "cry to any reporter that will listen that your business is 'failing'" and you have the Eddie Lampert (Sears/Kmart) strategy.
